[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model are clearly and completely described. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts fall within the protection scope of the present utility model.

[0026] Refer to Figures 1-6 , a positioning device for flexible circuit board processing, comprising: two electroplating racks 1, arranged in parallel, for placing the flexible circuit board 3, providing a stable support platform for the flexible circuit board 3, ensuring the position of the circuit board is fixed during processing and not prone to deviation; a connecting rod 2, arranged between the two electroplating racks 1, for adjusting the distance between the two electroplating racks 1, enabling flexible adjustment of the distance between the two electroplating racks 1 through adjustment, meeting the processing requirements of flexible circuit boards 3 of different sizes, and after positioning the flexible circuit board 3, the flexible circuit board 3 can be stretched and flattened by adjusting the distance between the two electroplating racks 1; a flexible circuit board 3, arranged between the two electroplating racks 1, as the processing object, its flexible characteristics enable it to adapt to different shapes and bending requirements during electroplating or other processing; several positioning seats 4, respectively connected to the two electroplating racks 1, arranged symmetrically, the positioning seats 4 are used to position the flexible circuit board 3 on the two electroplating racks 1, capable of firmly positioning the flexible circuit board 3 at a predetermined position, preventing movement or deformation during processing; the positioning seats 4 are arranged to be movable on the electroplating racks 1, for adjusting the position of the positioning seats 4 on the flexible circuit board 3, allowing the position of the positioning seats 4 to be adjusted according to the specific size and shape of the flexible circuit board 3, improving the versatility and flexibility of the device.

[0027] The positioning seat 4 includes: a control groove 401 opened on the positioning seat 4; a control board 402 connected in the control groove 401 and configured to rotate within the control groove 401; a positioning head 403 connected to the control board 402 for positioning the flexible circuit board 3; a limiting seat 404 installed on the control board 402, one end of the limiting seat 404 being in contact with the inner wall of the control groove 401 and configured to be movable on the control board 402 to limit the position of the control board 402 within the control groove 401; an elastic member 406 with one end connected to the control board 402 and the other end connected to the limiting seat 404, the elastic member 406 being used to provide a restoring force for the initial position of the limiting seat 404; when the control board 402 is in the initial position, the elastic action of the elastic member 406 can abut the limiting seat 404 against the inner wall of the control groove 401 to stably position the control board 402 within the control groove 401. When the control board 402 is rotated, the limiting seat 404 is squeezed by the inner wall of the control groove 401 and moves. After the control board 402 rotates 90 degrees, the limiting seat 404 abuts against the other inner wall of the control groove 401 again to stably position the control board 402 again. The elastic member 406 is made of a stainless steel spring or can also be made of elastic rubber; a handle 405 installed on the control board 402 to facilitate the operator to manually adjust the position of the control board 402, simplifying the operation process; a moving block 407 connected to the positioning seat 4, with a moving groove 103 opened on the electroplating rack 1, and the moving block 407 being connected in the moving groove 103, enabling the positioning seat 4 to move smoothly on the electroplating rack 1 while maintaining a stable positioning effect.

[0028] The electroplating rack 1 includes: a hanging plate 101 installed on the electroplating rack 1 for hanging the electroplating rack 1 in the electroplating bath; a positioning groove 102 opened on the electroplating rack 1 for placing the flexible circuit board 3. The hanging plate 101 facilitates hanging the electroplating rack 1 in the electroplating bath, while the positioning groove 102 provides an accurate placement position for the flexible circuit board 3, ensuring the consistency of processing.

[0029] The connecting rod 2 includes: two adjusting grooves 201 respectively opened at both ends of the connecting rod 2; two adjusting rods 202 respectively connected in the two adjusting grooves 201, with two electroplating racks 1 respectively connected to the two adjusting rods 202. The two adjusting rods 202 are configured to move closer to or away from each other simultaneously for adjusting the distance between the two electroplating racks 1; a control wheel 204 installed on the connecting rod 2; two lead screws 203 respectively connected to both sides of the control wheel 204, with one end of each of the two lead screws 203 respectively connected to the two adjusting rods 202. The lead screws 203 are used to control the movement of the adjusting rods 202 within the adjusting grooves 201, achieving precise adjustment of the distance between the two electroplating racks 1. By rotating the control wheel 204 to drive the lead screws 203 to move, the movement of the adjusting rods 202 within the adjusting grooves 201 is controlled, with simple operation and high adjustment accuracy.

[0030] During use, place the flexible circuit board 3 in the positioning groove 102 of the electroplating rack 1 to ensure the accurate and stable position of the circuit board. According to the size and shape of the flexible circuit board 3, adjust the position of the positioning seat 4 on the electroplating rack 1 to make the positioning seat 4 symmetrical and adaptable to the circuit board. Rotate the control board 402 through the handle 405 to align the positioning head 403 with the positioning points on the flexible circuit board 3. When the control board 402 rotates to an appropriate position, the limiting seat 404 will abut against the inner wall of the control groove 401 under the action of the elastic member 406 to stabilize the position of the control board 402. Repeat the above steps to adjust all the positioning seats 4 to ensure that the flexible circuit board 3 is firmly positioned on the two electroplating racks 1. If it is necessary to adjust the flatness or stretching degree of the flexible circuit board 3, rotate the control wheel 204 on the connecting rod 2. The rotation of the control wheel 204 will drive the movement of the lead screw 203 and control the movement of the adjusting rod 202 in the adjusting groove 201. By adjusting the distance between the two electroplating racks 1, the flexible circuit board 3 can be stretched and flattened to meet the processing requirements. After ensuring that the flexible circuit board 3 has been stably positioned and the flatness meets the requirements, start the electroplating or other processing operations. During the processing, the positioning seat 4 will keep the position of the flexible circuit board 3 fixed to prevent movement or deformation. After the processing is completed, rotate the control wheel 204 to restore the two electroplating racks 1 to the initial distance, loosen the handle 405 on the positioning seat 4, turn the control board 402 back to the initial position, take out the processed flexible circuit board 3, and clean the electroplating rack 1 and the positioning seat 4 to prepare for the next processing.

[0031] In summary, compared with the prior art, the following beneficial effects are achieved:

[0032] The flexible circuit board 3 is firmly positioned on the two electroplating racks 1 through the positioning seat 4, ensuring that the position of the circuit board is fixed during the entire electroplating process and is not prone to deviation. The positioning seat 4 is set to be movable on the electroplating rack 1, allowing the position of the positioning seat 4 to be adjusted according to the specific size and shape of the flexible circuit board 3, achieving rapid and accurate positioning of circuit boards of different sizes and improving production efficiency.

[0033] By adjusting the connecting rod 2, the distance between the two electroplating racks 1 can be controlled to meet the processing requirements of flexible circuit boards 3 of different sizes, and the circuit board can also be flattened during positioning. The mobility and adjustability of the positioning seat 4 also enable the device to flexibly handle circuit boards of various shapes and sizes, improving the versatility and flexibility of the device.
