Description

Technical Field

[0001] This utility model relates to the technical field of PCB board processing, and in particular to an electroplating hanger for PCB board processing. Background Technology

[0002] In the electroplating process of PCB board processing, electroplating racks are used to support and fix the PCB board so that it can complete the plating process in the electroplating solution. Existing electroplating racks have many shortcomings. The fixing structure mostly uses metal parts to directly clamp the PCB board, which can easily cause scratches and indentations on the edges of the PCB board, seriously affecting the electroplating quality. In addition, the position of the fixing seat is not adjustable, so it cannot be adapted to PCB boards of different sizes. A single fixing seat can only fix one PCB board, resulting in low electroplating efficiency and difficulty in meeting the needs of mass production of PCB boards.

[0003] To address the aforementioned issues, an electroplating hanger for PCB board processing is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide an electroplating rack for PCB board processing, so as to solve the problem of the existing electroplating racks for PCB board processing mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an electroplating hanger for PCB board processing, comprising a hanger frame, a cross, a fixing seat, a slot, a first bolt, a stop post, a first silicone pad, and a second silicone pad; The inner wall of the hanging frame is welded with a cross, and each of the four sets of rods of the cross is equipped with a set of fixing seats. The fixing seats are provided with slots for placing the edge of the PCB board. The fixing seats are equipped with first bolts, and the inner wall of the slots is connected to a stop post. The stop post is provided with a first silicone pad, and the end of the first bolt is provided with a second silicone pad, which cooperates with the first silicone pad to provide buffer protection for both sides of the PCB board edge.

[0006] Preferably, the device also includes a mounting bracket and a second bolt. The mounting bracket is provided on the top of the bracket frame, and the second bolt is mounted on the mounting bracket. The second bolt is used to fix the mounting bracket to the external equipment.

[0007] Preferably, the fixing seat is provided with a through hole, and the horizontal and vertical rods of the cross are both inserted into the corresponding through holes, so that the fixing seat can move along the rods of the cross to adjust its position.

[0008] Preferably, it also includes a third bolt and a third silicone pad. The third bolt is installed on both sides of the fixing seat, and the end of the third bolt is provided with a third silicone pad. The end of the third bolt abuts against the rod of the cross through the third silicone pad, thereby locking and fixing the fixing seat from both sides.

[0009] Preferably, the first silicone pad, the second silicone pad, and the third silicone pad are all made of silicone material that is resistant to electroplating solution corrosion, and the surface is provided with anti-slip texture.

[0010] Preferably, there are two mounting brackets, symmetrically arranged on both sides of the top of the bracket frame, and each mounting bracket is provided with two second bolts to enhance the stability of the mounting.

[0011] Preferably, the fixing seat has slots on both sides, and each slot is equipped with a first bolt, a stop post, a first silicone pad and a second silicone pad, so that a single fixing seat can fix two PCB boards at the same time, thereby enabling the bracket frame to fix two sets of PCB boards at one time.

[0012] Compared with the prior art, the beneficial effects of this utility model are: The first, second, and third silicone pads are all made of silicone material that is resistant to electroplating solution corrosion and has anti-slip textures on the surface. This prevents metal parts from directly contacting the PCB board and causing scratches or indentations, effectively protecting the surface quality of the PCB board and the service life of the bracket components. At the same time, the anti-slip textures enhance the stability of the fixation and prevent the PCB board and the mounting base from shifting. The mounting base is installed on the cross-shaped rod through the through hole and can move freely along the rod. It is locked in place from both sides by the third bolt. The spacing of the mounting base can be flexibly adjusted according to the PCB board of different sizes, and it is compatible with the electroplating process of various PCB boards, which significantly improves the versatility of the bracket. The mounting base has slots on both sides, and two PCB boards can be clamped simultaneously in the slots on both sides of a single mounting base, enabling simultaneous processing of two boards. Compared with traditional single-slot brackets, the electroplating processing efficiency is significantly improved. Attached Figure Description

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0016] Example like Figure 1-4 As shown, an electroplating hanger for PCB board processing includes a hanger frame 1, a cross 2, a fixing seat 3, a slot 4, a first bolt 5, a support post 6, a first silicone pad 7, a second silicone pad 8, a hanging seat 9, and a second bolt 10.

[0017] It should be noted that in this embodiment, a cross 2 is welded to the inner wall of the bracket frame 1. A set of fixing seats 3 is installed on each of the four sets of rods of the cross 2. The fixing seats 3 have slots 4 for placing the edge of the PCB board. The first bolt 5 is installed. The inner wall of the slot 4 is connected to the abutment 6. The abutment 6 is provided with a first silicone pad 7. The end of the first bolt 5 is provided with a second silicone pad 8. The two work together to buffer and clamp the edge of the PCB board. Two hanging seats 9 are symmetrically arranged on the top of the bracket frame 1. Each hanging seat 9 is equipped with two second bolts 10 to fix the hanging seat 9 to the external electroplating equipment and enhance the hanging stability. The fixing seats 3 are provided with through holes 11. The horizontal and vertical rods of the cross 2 pass through the through holes 11, so that the fixing seats 3 can move along the rods of the cross 2 to adjust the position.

[0018] like Figure 3 , 4 As shown, based on Embodiment 1, it further includes a third bolt 12, a third silicone pad 13, and optimizes the slot structure of the fixing seat 3.

[0019] It should be noted that in this embodiment, the fixing seat 3 is equipped with a third bolt 12 on both sides, and a third silicone pad 13 is provided at the end of the third bolt 12. When the third bolt 12 is tightened, the third silicone pad 13 presses against the rod of the cross 2, locking the fixing seat 3 from both sides to prevent it from shifting during the electroplating process. The fixing seat 3 is provided with slots 4 on both sides, and each slot 4 is equipped with a first bolt 5, abutment 6, first silicone pad 7 and second silicone pad 8. A single fixing seat 3 can fix two PCB boards at the same time, so that the bracket frame 1 can fix two sets of PCB boards at one time, improving the electroplating processing efficiency. The first silicone pad 7, the second silicone pad 8 and the third silicone pad 13 are all made of silicone material that is resistant to electroplating solution corrosion, and the surface is provided with anti-slip texture, which not only avoids electroplating solution corrosion, but also enhances the anti-slip fixing effect on the PCB board and the fixing seat.

[0020] The first bolt 5 is threaded into the corresponding threaded hole on the fixing seat 3. The depth of insertion into the groove 4 can be adjusted by rotation to clamp or loosen the PCB board. The second bolt 10 passes through the mounting hole of the bracket seat 9 and is threaded into the threaded interface of the external electroplating equipment to fix the bracket. The third bolt 12 is threaded into the corresponding threaded hole on the fixing seat 3. Rotation can drive the third silicone pad or 13 to press against and disengage from the cross 2 rod to lock and unlock the fixing seat. All parts of the device are made of materials resistant to electroplating solution corrosion. The bracket frame 1, cross 2, first bolt 5, second bolt 10, third bolt 12 and bracket seat 9 are made of 304 or 316L stainless steel. The fixing seat 3 is made of high-strength aluminum alloy anodized material. The first silicone pad 7, second silicone pad 8 and third silicone pad 13 are made of fluorosilicone. The above materials can withstand the corrosion of conventional electroplating solutions, avoid component corrosion and contamination of the PCB board or affect service life, and ensure the stability of the electroplating process.

[0021] Working principle of this utility model: Refer to the instruction manual appendix Figure 1-4 The fixing seat 3 is sleeved on the rod of the cross 2 through the through hole 11. It can be moved along the rod to a suitable position. The edge of the PCB board is placed into the slot 4 of the fixing seat 3. After adjustment, the third bolts 12 on both sides of the fixing seat 3 are tightened so that the third silicone pad 13 presses against the rod of the cross 2. The fixing seat 3 is locked from both sides to ensure its position is stable. The abutment 6 on the inner wall of slot 4 contacts one side of the PCB board through the first silicone pad 7. Tighten the first bolt 5 so that the second silicone pad 8 at the end contacts the other side of the PCB board. The first silicone pad 7 and the second silicone pad 8 cooperate to buffer and clamp the edge of the PCB board from both sides, so as to avoid damage to the PCB board and fix it firmly. The double slots of a single fixing seat 3 can clamp two PCB boards at the same time, so as to realize the synchronous processing of dual boards. The bracket is fixed to the external electroplating equipment by means of the bracket 9 at the top of the bracket frame 1 and the second bolt 10. The two symmetrical brackets 9 are each equipped with two second bolts 10 to enhance the stability of the bracket and prevent the bracket from shaking during the electroplating process. The first, second, and third silicone pads 13 are made of silicone material that is resistant to electroplating solution corrosion. The anti-slip texture on the surface not only prevents the electroplating solution from corroding the components, but also enhances the anti-slip fixing force on the PCB board and the anti-slip locking force on the fixing seat 3, ensuring that the PCB board is not damaged during clamping and electroplating.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
