[0037] like Figures 1 to 3 As shown, in this embodiment, both ends of the pressure cover 8 are provided with limit pressure blocks 10 for floating downward, and the limit pressure blocks 10 cooperate with the positioning groove 5. The limit pressure blocks 10 have the effect of floating downward, so when the pressure cover 8 is pressed on the positioning seat 4, the two limit pressure blocks 10 will press the two ends of the capacitive stylus, so that the capacitive stylus is firmly fixed in the positioning groove 5, and the positioning and fixing are realized.

[0038] like Figures 1 to 3 As shown, in this embodiment, both ends of the front side of the pressure cover 8 are provided with floating buckles 11, and the floating buckles 11 cooperate with the positioning blocks 12 provided at the front end of the positioning seat 4, and the middle part of the pressure cover 8 is provided with a clearance notch 13 that cooperates with the component positioning mechanism 7;

Through the cooperation between the sensing sheet 15 and the sensor 16, it can be detected whether the rotating seat 2 returns to the original position, so as to better control it.

[0042] like Figures 1 to 10 As shown, the working principle of the present invention is:

[0043] The operator places the capacitive pen product in the positioning groove 5, and makes the left end of the capacitive pen product contact with the limit block, and the right end is on the U-shaped groove block 623, and then moves the elastic breaking block 625 to move the U-shaped groove block 623 to the left, thereby preliminarily fixing the capacitive pen product in the positioning groove 5, and then presses down the pressure cover 8 and locks the floating buckle 11 to achieve complete fixation of the capacitive pen product;

[0044] Then the staff takes the parts and places them at the welding position of the capacitive pen product. At the same time, the soft flat cable connected to the parts is combed to the right, and then the limit pressing plate 723 is turned down to limit the parts. Then the embossed handle 715 is pulled and rotated, and after alignment, it is released so that the fixing plate 714 presses the front end of the parts. Since the parts fit the contour of the capacitive pen product, the parts can be closely attached to the capacitive pen product and firmly fixed.

[0045] After the components are fixed, the limiting pressure plate 723 is turned up, and after the flexible flat cable is arranged, the flexible flat cable is pulled backward and upward to expose the right welding point of the component, and then the flexible flat cable is clamped by the upper fixing block 93 and the lower fixing block 92 to complete the welding preparation work;

[0046] Finally, welding work is performed on the components and capacitive pen products using welding equipment.

[0047] Although the embodiments of the present invention are described with practical solutions, they do not constitute limitations on the meaning of the present invention. For those skilled in the art, it is obvious to modify the implementation scheme and combine it with other solutions based on this description.
