Abstract
Description
Technical Field
[0001] The utility model relates to a PCB board electroplating hanger, in particular to an electroplating hanger with a floating clamping point positioning function. Background Art
[0002] In the prior art PCB plating hangers, the clamp of a hanger is usually only suitable for clamping PCB boards within a specified thickness range, and cannot achieve compatibility with thin boards and thick boards. At the same time, the structural design of the existing hanger also has the following disadvantages: the rotating chuck is a fixed structure, and the fixed clamping point is a flat structure. When rotating and clamping, it cannot achieve compatibility when clamping thin boards (0.06mm) and thick boards (1.5mm). In addition, when rotating the clamping plate, the movement trajectory of the rotating clamping point is an arc shape, which will cause the board to warp due to internal friction. Therefore, it is difficult for the existing PCB plating hanger to prevent the board from bending and deformation after being placed. Utility Model Content

[0017] The present invention will be described in more detail below with reference to the accompanying drawings and embodiments.
[0018] The utility model discloses an electroplating hanger with a floating clamping point positioning function, combined with Figures 1 to 5 As shown, it includes a square frame 1, the frame 1 includes two left and right side frames 10, the two side frames 10 are respectively provided with a floating clamping point mechanism 2, the floating clamping point mechanism 2 includes two arms 20 and a rotating rod 21, the first ends of the two arms 20 are respectively fixed to the upper and lower ends of the frame 1, the rotating rod 21 is rotatably connected between the second ends of the two arms 20, and at least one conical fixed clamping point 11 is fixed on the side frame 10, and the end of the conical fixed clamping point 11 A through hole 101 is used to pass through the edge position of the PCB board 100. A pressure plate 22 is fixed on the rotating rod 21. At least one columnar active clamping point 23 is provided on the pressure plate 22. The columnar active clamping point 23 corresponds to the conical fixed clamping point 11 one by one. When the rotating rod 21 rotates at a preset angle, the columnar active clamping point 23 is pressed on the end of the conical fixed clamping point 11, and the PCB board 100 is clamped by the columnar active clamping point 23 and the conical fixed clamping point 11.
[0019] In the above structure, the frame 1 is a whole frame of the hanger, which is in a square frame shape, and the left and right side frames 10 are respectively provided with floating clamping point mechanisms 2. When the rotating rod 21 is rotated to a preset angle, the pressing plate 22 drives the columnar active clamping point 23 to be pressed against the end of the conical fixed clamping point 11. Since the end of the conical fixed clamping point 11 passes through the through hole 101 at the edge of the PCB board 100, the PCB board 100 can be mounted by using the cooperation of the columnar active clamping point 23 and the conical fixed clamping point 11. 00 reinforcement, compared with the structure of the plane clamp in the prior art, the end-to-end matching mode of the columnar movable clamping point 23 and the conical fixed clamping point 11 in the utility model can be compatible with clamping PCB boards of various thicknesses. At the same time, because the position of the conical fixed clamping point 11 is fixed and the conical fixed clamping point 11 can pass through the through hole 101 at the edge of the PCB board 100, it avoids generating additional stress when clamping the PCB board, thereby preventing the PCB board from warping and deformation, which is helpful to improve the quality of the electroplating process.
[0020] In this embodiment, when the rotating rod 21 rotates to a preset angle, the rotating rod 21 should be locked in the rotated position. Figure 2 The frame body 1 is provided with a locking mechanism 3, and the locking mechanism 3 is used to lock the rotating rod 21 at the preset angle position after the rotating rod 21 rotates at the preset angle.
[0021] Furthermore, the locking mechanism 3 includes a lever 30 and a lever lock 31, wherein the first end of the lever 30 is fixedly connected to the rotating rod 21, the second end of the lever 30 extends toward the side of the rotating rod 21, and the lever lock 31 is used to lock the second end of the lever 30. The lever 30 may be a strip lever, and the lever lock 31 may be a self-locking elastic lock.
[0022] As a preferred embodiment, a torsion spring 24 is sleeved on the rotating rod 21, and the torsion spring 24 is used to drive the rotating rod 21 to rotate so that the columnar active clamping point 23 is away from the conical fixed clamping point 11. In practical applications, when the electroplating process is completed and the PCB board is ready to be removed, the locking function of the lever lock 31 on the lever 30 can be contacted, and at this time, the torsion spring 24 can be used to drive the rotating rod 21 to rotate in the opposite direction by a preset angle, so that the columnar active clamping point 23 is automatically opened relative to the conical fixed clamping point 11.
[0023] Regarding the preferred structure of the columnar active clamping point 23, in this embodiment, combined with Figures 3 to 5 As shown, the columnar movable clamping point 23 includes a clamping point support 230, a clamping point body 231 and a soft rubber sleeve 232. The first end of the clamping point body 231 is inserted into the clamping point support 230, and the clamping point body 231 and the clamping point support 230 are hinged by a pin 233. The soft rubber sleeve 232 is sleeved on the outside of the clamping point body 231 and the clamping point support 230. Based on the above structural setting, there is a movable margin between the clamping point body 231 and the clamping point support 230, which can avoid the rigid contact between the columnar movable clamping point 23 and the conical fixed clamping point 11. Among them, the soft rubber sleeve 232 can play an insulating role and limit the movable margin of the clamping point body 231.
[0024] In order to assist in clamping the PCB board, in the present embodiment, an auxiliary stop block 12 is fixed on the side frame 10 adjacent to the conical fixing clamping point 11, an auxiliary clamping plate 25 is fixed on the rotating rod 21, and a pressing head 26 corresponding to the auxiliary stop block 12 is provided on the auxiliary clamping plate 25. When the rotating rod 21 rotates at a preset angle, the pressing head 26 and the auxiliary stop block 12 clamp the PCB board 100.
[0025] It should be noted here that the present invention is not limited to the above structural details in practical applications, that is, any equivalent clamping structure that can achieve the above floating clamping point positioning function belongs to the protection scope of the present invention.
[0026] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions or improvements made within the technical scope of the present invention should be included in the scope of protection of the present invention.
