[0027] A welding pressure head assembly provided in an embodiment of the present invention can be applied to backlight module FPC welding, including a pressure head 6 and a lifting power unit and a pressure head horizontal adjustment device 5, wherein the pressure head horizontal adjustment device 5 specifically includes an X-axis support seat 510, an X-axis adjustment seat 511, an X-axis adjustment micrometer 512, an X-axis rotation axis 513, an X-axis compression spring, and a Y-axis support seat 520, a Y-axis adjustment seat 521, a Y-axis adjustment micrometer 522, a Y-axis rotation axis 523 and a Y-axis compression spring 524, wherein a first horizontal through groove is provided at the bottom of the X-axis support seat 510, the X-axis adjustment seat 511 is hinged in the first horizontal through groove through the X-axis rotation axis 513, the two ends of the X-axis compression spring are respectively connected to the X-axis adjustment seat 511 and the inner top of the first horizontal through groove, and the X-axis adjustment micrometer 512 is used to adjust the X-axis adjustment seat 51 1 rotates around the X-direction rotation axis 513 under the support of the X-direction compression spring 514, and the lifting end of the lifting power unit is fixedly connected to the X-direction support seat 510; the Y-direction support seat 520 is fixed to the bottom of the X-direction adjustment seat 511, and a second horizontal through groove is provided at the bottom of the Y-direction support seat 520, and the second horizontal through groove is perpendicular to the first horizontal through groove. The Y-direction adjustment seat 521 is hinged in the second horizontal through groove through the Y-direction rotation axis 523, and the two ends of the Y-direction compression spring are respectively connected to the Y-direction adjustment seat 521 and the inner top of the second horizontal through groove. The Y-direction adjustment micrometer 522 is used to adjust the Y-direction adjustment seat 521 to rotate around the Y-direction rotation axis 523 under the support of the Y-direction compression spring 524, and the pressure head 6 is fixed to the bottom of the Y-direction adjustment seat 521, wherein a pressure head fixing plate 9 is provided at the bottom of the Y-direction adjustment seat 521, and the pressure head 6 is installed on the pressure head fixing plate 9. When the horizontal position of the pressure head 6 needs to be adjusted, by screwing the X-direction adjusting micrometer 512, the X-direction adjusting seat 511 will rotate and then drive the Y-direction supporting seat 520 to rotate, thereby driving the pressure head 6 to rotate around the X-direction rotating axis 513, and by screwing the Y-direction adjusting micrometer 522, the Y-direction adjusting seat 521 will rotate around the Y-direction rotating axis 523, thereby driving the pressure head 6 to rotate, that is, the X-direction adjusting micrometer 512 and the Y-direction adjusting micrometer 522 can be used to adjust the horizontality of the pressure head. The traditional screw adjustment method requires at least three screws to achieve the horizontality adjustment. The welding pressure head assembly only needs to adjust the horizontality through the X-direction adjusting micrometer 512 and the Y-direction adjusting micrometer 522, thereby improving the adjustment efficiency and indirectly improving the utilization rate. In addition, the micrometer has a scale, which can improve the accuracy of the horizontal adjustment.

[0028] Specifically, a plurality of X-direction compression springs are provided in the first horizontal through slot, and a plurality of Y-direction compression springs are provided in the second horizontal through slot. The accompanying drawings take two X-direction compression springs and a Y-direction compression spring as examples for illustration. By using a plurality of compression springs, the deflection problem can be prevented.

[0029] The welding pressure head assembly provided in this embodiment also includes a pulse power supply connecting device, one end of which is fixed directly below the horizontal adjustment device, and the other end is fixed on the lifting power part, and is divided into two channels, positive and negative. The pulse power supply connecting device specifically includes an elastic copper sheet 8 and a cable fixing plate 7. The cable fixing plate 7 is fixed on the lifting power part. One end of the elastic copper sheet 8 is fixed to the cable fixing plate 7, and the other end is connected to the pressure head fixing plate 9.

[0030] During actual production, the welding product is moved to the bottom of the pressure head 6, and the lifting power unit drives the pressure head 6 to press down. After the pressure head 6 contacts the product, the pulse current is transmitted to the surface of the pressure head 6 through the pulse power supply connection device, causing the bottom surface of the pressure head 6 to heat up. After the temperature reaches the set temperature and the temperature is maintained for a set time, the pulse power supply is turned off and the heating stops. After the surface of the pressure head 6 cools down to the solidification point of tin, the lifting power unit drives the pressure head 6 to rise, and the product soldering process is completed.

[0031] Specifically, the lifting power unit includes a Z-axis driving device 2 and a pressure cylinder 4. The Z-axis driving device 2 is used to drive the pressure cylinder 4 to rise and fall. The telescopic end of the pressure cylinder 4 is fixedly connected to the X-axis support seat 510, that is, the lifting power unit controls the height position of the pressure cylinder 4, and the pressure cylinder 4 provides the pressure during welding, so that the welding height and pressure can be accurately controlled during the welding process, thereby improving the product yield.

[0032] In order to ensure the stable lifting of the pressure cylinder 4, it also includes a mounting base plate 1 and a lifting fixed plate 3. The lifting fixed plate 3 is connected to the mounting base plate 1 for sliding up and down. The fixed end of the Z-axis driving device 2 is fixed on the mounting base plate 1. The telescopic end of the Z-axis driving device 2 is fixedly connected to the lifting fixed plate 3. The fixed end of the pressure cylinder 4 is installed on the lifting fixed plate 3. The lifting fixed plate 3 and the mounting base plate 1 can be connected for sliding up and down through a slide rail, so it can guide the pressure cylinder 4.

[0033] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0034] The above is a detailed introduction to a welding pressure head assembly provided by the present invention. This article uses specific examples to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method of the present invention and its core idea. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the present invention, the present invention can also be improved and modified in a number of ways, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
