[0002] Circuit boards provide a stable mounting platform for various electronic components and can provide accurate signal paths between electronic components.

[0003] Electroplating is a crucial step in circuit board manufacturing. During this process, workers need to transfer circuit boards multiple times between various electroplating tanks. To electroplat multiple circuit boards at once, they are typically placed in a hanging basket for electroplating. However, as shown in the hanging basket for circuit board electroplating disclosed in application number 201721847564.4, this basket can only hold circuit boards of one specification, and the redundant outer shell affects the contact between the electroplating solution and the circuit board. Therefore, improvements are needed. Utility Model Content

[0026] Reference Figures 1-3 According to an embodiment of the present invention, a fixture for electroplating circuit boards includes a frame 11 and a support plate 12. The frame 11 is provided with a through-groove 13. A first sliding groove 14 is provided on the left and right sides of the through-groove 13. The first sliding groove 14 is distributed vertically at equal distances and is through-groove. The support plate 12 is provided with multiple sliding grooves arranged vertically and inserted into the first sliding grooves 14. The fixture also includes a layout mechanism for locking the support plate 12 relative to the front and rear positions of the frame 11. In addition, multiple pressure plates 15 are slidably connected to the support plate 12 from left to right. The fixture also includes a locking mechanism for controlling the gap between the pressure plates 15.

[0027] The operator needs to place the circuit board between the pressure plates 15, and then clamp each pressure plate 15 using the locking mechanism to hold the circuit board between the pressure plates 15. At this time, the circuit board is installed and fixed on the support plate 12. Then, the operator inserts the support plate 12 into the first slide groove 14, and arranges the support plate 12 vertically in the receiving groove 13 according to the vertical height of the circuit board and the support plate 12, so as to install as many circuit boards as possible on the frame 11. Then, the operator uses the layout mechanism to lock the support plate 12 in the frame 11. After that, the external transfer device can transfer the circuit board electroplating fixture to each electroplating tank through the hanging ring provided on the frame 11 for electroplating.

[0028] In this embodiment, the layout mechanism includes a sliding plate 16 that is slidably connected to the left side of the frame 11. Abutment plates 17 are integrally formed at the front and rear edges of the right side of the sliding plate 16. The two abutment plates 17 are located on the front and rear sides of the frame 11, respectively. A bolt 19 is rotatably connected to the left side of the frame 11 and is threaded to the sliding plate 16. In addition, an elastic layer 18 is provided on the right side of the abutment plate 17, and the elastic layer 18 can press against the left side of the support plate 12.

[0029] That is, the operator can rotate the first bolt 19 and cause the slide plate 16, the abutment plate 17 and the elastic layer 18 to move to the right, so that the elastic layer 18 pushes the bearing plate 12 to the right and clamps the bearing plate 12.

[0030] The locking mechanism includes a threaded hole 20 located on the right side of the receiving groove 13. Multiple threaded holes 20 are arranged vertically, and the threaded holes 20 are offset vertically from the first slide groove 14. A second bolt 21 is screwed into the threaded hole 20 on the upper side of the first slide groove 14 on which the bearing plate 12 is mounted, and the left end of the second bolt 21 abuts against the rightmost pressure plate 15.

[0031] That is, the operator can rotate the threaded hole 20 and move it to the left, so that the threaded hole 20 pushes the rightmost pressure plate 15 to the left, thereby clamping the circuit board between the pressure plates 15.

[0032] In a second embodiment of the circuit board electroplating fixture, in order to allow the spacing between the pressure plates 15 to automatically recover when the operator unscrews the second bolt 21 to the right, so as to facilitate the operator in placing or removing the circuit board, springs 22 are respectively provided on the front and rear sides of the right side of the pressure plate 15. In order to prevent the springs 22 from affecting the minimum distance between the pressure plates 15 and thus affecting the clamping force on the circuit board, slots are respectively provided on the front and rear sides of the right side of the pressure plate 15, and the springs 22 are placed in the slots.

[0033] In addition, the support plate 12 is provided with a plurality of through-holes to facilitate the rapid contact between the electroplating solution and the circuit board when it is immersed in the electroplating bath, and to facilitate the rapid flow of the electroplating solution when the circuit board electroplating fixture is lifted upward.

[0034] The above description is only a specific embodiment of the present utility model, but the technical features of the present utility model are not limited thereto. Any changes or modifications made by those skilled in the art within the scope of the present utility model are covered by the patent scope of the present utility model.
