完整代码如下：

<template>
  <cu-form ref="form" :model="form">
    <cu-form-item label="设备号" prop="imei" required>
      <el-autocomplete v-model="form.imei" :fetch-suggestions="querySearch" @select="handleSelect"></el-autocomplete>
    </cu-form-item>
    <cu-form-item label="安装时间">
      <view class="uni-date">{{ form.installTime }}</view>
    </cu-form-item>
    <cu-form-item label="安装地点">
      <span class="flex1 text-right text-cut">{{ form.address }}</span>
    </cu-form-item>
  </cu-form>
</template>

<script>
  import { ref } from 'vue'
  import { queryDevices } from '@/api/device'
  export default {
    setup() {
      const form = ref({
        imei: '',
        installTime: '',
        address: ''
      })

      const querySearch = async (queryString, cb) => {
        const res = await queryDevices({ keyword: queryString })
        const options = res.data.map(item => ({ value: item.imei, label: item.imei }))
        cb(options)
      }

      const handleSelect = (item) => {
        form.imei = item.value
      }

      return {
        form,
        querySearch,
        handleSelect
      }
    }
  }
</script>

其中，我们使用了Vue 3的composition API，并引入了一个queryDevices方法来异步获取设备列表，然后将其转化为el-autocomplete组件可以接受的格式。当用户在el-autocomplete组件中输入关键字时，会通过querySearch方法异步获取匹配的设备列表并显示在下拉选项中。当用户选中某个选项时，会触发handleSelect方法将选中的设备号赋值给form.imei。同时，我们使用了element-ui中的el-autocomplete组件来替换原来的input标签，实现了模糊搜索的输入框。
