[0003] But the existing SMT patch mounting clamping device has the following problems when using:

[0004] The existing patch mounting clamping device is difficult to adjust to the appropriate height quickly and accurately according to different patch mounting requirements when using, which not only reduces the production efficiency, but also may cause the patch mounting position to deviate due to inappropriate height, affecting product quality. In terms of stability, the device is driven by double-headed screw during operation, and may shake and deviate during sliding, so that the accuracy of the position cannot be guaranteed when clamping the patch, thereby affecting the precision and reliability of patch installation, increasing the rate of defective products. In addition, the clamping plate on the existing clamping device is only attracted by magnet, and the temperature in the workshop may fluctuate in actual production environment.
