Description

Technical Field

[0001] This application relates to the field of assistive devices, and in particular to a novel circuit board plating copper angled insertion basket rack. Background Technology

[0002] The copper plating basket is mainly used in the PCB copper plating process. The copper plating basket fixes the circuit board in the electroplating tank, ensuring that the electroplating solution evenly covers the copper layer surface and achieves uniform deposition of copper foil on the circuit board.

[0003] In related technologies, the copper plating baskets used in PCB copper plating processes typically employ vertical sub-basket placement racks, meaning the copper plating baskets are vertically oriented and the PCB boards are vertically suspended on the copper plating basket placement racks.

[0004] However, when placing small-hole PCBs (hole diameter ≤ 0.25MM) using the aforementioned vertical sub-basket placement rack, air bubbles are easily trapped in the PCBs, resulting in no copper inside the holes and non-conductive conductive holes. This leads to low-quality PCBs, waste of chemicals, and increased processing costs, so there is still room for improvement. Summary of the Invention

[0005] The purpose of this application is to provide a novel PCB plating copper slanted insert basket placement rack to avoid the problem of non-conductive conductive holes with bubble-like structures on the PCB, thereby improving the plating copper quality of the PCB and saving costs.

[0006] To achieve the objectives of this application, the technical solution adopted is as follows: A novel PCB plating inclined insertion basket rack includes a support frame and a fixing frame for supporting the PCB board. The fixing frame is disposed on the support frame. The support frame is provided with a first slot, and the fixing frame is provided with a second slot. The first slot and the second slot are staggered. The first slot and the second slot respectively abut against the opposite two sides of the PCB board. When the PCB board is placed on the support frame, the PCB board is inclined to the ground.

[0007] Furthermore, the angle between the PCB board placed on the support frame and the projection of the PCB board in the vertical direction is in the range of 4-8 degrees.

[0008] Furthermore, the support frame is provided with a side frame, and the side frame has an inclined slot. The complementary angle of the inclined angle formed between the inclined slot and the ground is equal to the angle between the PCB board placed on the support frame and the projection of the PCB board in the vertical direction. When the PCB board is placed on the support frame, the inclined slot abuts against the side of the PCB board. The side frame is used to fix the side of the PCB board placed on the support frame.

[0009] Furthermore, two fixing brackets are provided, and the two fixing brackets are respectively fixed on both sides of the support frame. The fixing brackets are used to fix the top of the PCB board placed on the support frame.

[0010] Furthermore, a connecting rod is fixed on the support frame, the side frame is hinged to the support frame, the side frame and the connecting rod are fixedly connected by a connecting collar, a first connecting post is fixed on the connecting rod, one end of the connecting collar is sleeved on the first connecting post, a second connecting post is fixed on the side frame, and rotating the side frame allows the other end of the connecting collar to be sleeved on the second connecting post, thereby fixing the side frame and the connecting rod.

[0011] Furthermore, the fixing frame includes two vertical rods, two connecting rods, and a horizontal rod. The two ends of the horizontal rod are fixedly connected to one end of each of the two connecting rods, and the other ends of each of the two connecting rods are rotatably connected to one end of each of the two vertical rods. The other ends of the two vertical rods are fixedly connected to the support frame. The second slot is opened at the bottom of the horizontal rod. A fixing component is provided on the connecting rod, and the connecting rod and the vertical rod are fixed together by the fixing component.

[0012] Furthermore, the fixing component includes a rotating ring and a fixing collar. The rotating ring is fixed to one end of the connecting rod near the vertical rod. The rotating ring is rotatably connected to the vertical rod. Rotation of the rotating ring allows the connecting rod to rotate relative to the vertical rod. A limiting rod is fixed on the rotating ring. One end of the fixing collar is sleeved on the limiting rod, and the other end of the fixing collar is used to sleeve on a limiting rod on the rotating ring of another connecting rod of the fixing frame to fix the rotating ring to the vertical rod.

[0013] Furthermore, the support frame includes a vertical bracket and a horizontal frame, the vertical bracket is vertically fixed to the horizontal frame, the first slot is opened on the horizontal frame, and the vertical rod is fixed to the vertical bracket.

[0014] Furthermore, the width of the side frame ranges from 2 to 5 cm.

[0015] Furthermore, a pull rod is fixed to the connecting rod.

[0016] The beneficial effects of this application are: This application utilizes a support frame and a fixing frame. The support frame has a first slot, and the fixing frame has a second slot. The first and second slots are staggered. The PCB board is placed on the support frame, and the first and second slots abut against the opposite sides of the PCB board. The PCB board is tilted relative to the ground. After the PCB board is placed, the upper and lower ends of the PCB board are tilted at a certain angle to the vertical direction, which facilitates the escape of air bubbles from the small holes. This avoids the problem of non-conductive conductive holes caused by air bubbles in the PCB board. For small-hole PCB boards (hole diameter ≤ 0.25MM), this application greatly reduces the defect rate of copper-free holes caused by air bubbles, improves product quality and production efficiency, and has a simple structure, uses affordable materials, is highly efficient and practical, easy to operate, and has strong promotion potential.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Unless otherwise defined, the technical or scientific terms used herein should have the ordinary meaning understood by those skilled in the art to which this application pertains. The terms "comprising" and similar expressions used herein mean that the element or object preceding the word covers the element or object listed following the word and its equivalents, but does not exclude other elements or objects.

[0023] This embodiment provides a novel circuit board plating copper slanted insertion basket placement rack. In this embodiment, refer to... Figure 1 and Figure 2 This novel PCB plating inclined insertion basket rack includes a support frame 1 and a fixing frame 2 for supporting the PCB board. The support frame 1 includes four vertical supports 101 and two horizontal frames 102. The four vertical supports 101 are vertically fixed to both ends of one side of each horizontal frame 102. There are two fixing frames 2, which are arranged in parallel. One fixing frame 2 is fixed to the vertical support 101 on one of the horizontal frames 102, and the other fixing frame 2 is fixed to the vertical support 101 on the other horizontal frame 102. A first slot 3 is provided at the top of the horizontal frame 102, and a second slot 4 is provided at the bottom of the fixing frame 2. The first slot 3 and the second slot 4 are staggered. The PCB board is placed on the horizontal frame 102, with the bottom edge of the PCB board receiving in the first slot 3 and the top edge of the PCB board receiving in the second slot 4. The first slot 3 abuts against the bottom edge of the PCB board, and the second slot 4 abuts against the top edge of the PCB board. The first slot 3 and the second slot 4 together limit the position of the PCB board. When the PCB board is placed on the horizontal frame 102, the PCB board is tilted to the ground, and the angle between the PCB board placed on the horizontal frame 102 and the projection of the PCB board in the vertical direction is 4-8 degrees.

[0024] The novel PCB copper plating inclined insertion basket placement rack of this application tilts the PCB board at a certain angle to the vertical direction after the PCB board is placed. This facilitates the escape of air bubbles from the small holes, thus avoiding the problem of non-conductive conductive holes caused by air bubbles. For small-hole PCB boards (hole diameter ≤ 0.25MM), this application significantly reduces the defect rate of copper-free holes caused by air bubbles, improves product quality and production efficiency, and has a simple structure, uses economical materials, is highly efficient and practical, easy to operate, and has strong applicability. It also saves on chemical reagents, thereby reducing processing costs.

[0025] Furthermore, a side frame 5 is hinged between the two vertical supports 101 on each horizontal frame 102. The side frame 5 has an angled slot 6, the complementary angle of which is equal to the angle between the PCB board placed on the horizontal frame 102 and its projection in the vertical direction. When the two side frames 5 are vertical, the distance between them is greater than the width of the PCB board. When the operator places the PCB board, the side frame 5 rotates to a vertical position, at which point the side frame 5 does not contact the side of the PCB board, thus eliminating any obstruction to the PCB board placement. After the PCB board is placed on the horizontal frame 102, the operator rotates the side frame 5 so that the wall of the angled slot 6 abuts against the side of the PCB board, at which point the side frame 5 is tilted. The side frame 5 fixes the side of the PCB board placed on the horizontal frame 102, and the fixing bracket 2 fixes the top of the PCB board placed on the horizontal frame 102, thereby enhancing the stability of the PCB board. The width of the side frame 5 ranges from 2 to 5 cm. By setting a reasonable width for the side frame 5, the occupancy area of ​​the PCB board can be reduced while ensuring the fixing effect of the side frame 5, which is conducive to the uniform deposition of copper foil.

[0026] Furthermore, a connecting rod 8 is horizontally fixed between the vertical support 101 on one horizontal frame 102 and the vertical support 101 on the other horizontal frame 102. Since the side frame 5 is hinged to the vertical support 101, the side frame 5 can rotate relative to the vertical support 101. Because each placement rack needs to hold a large number of PCB boards, the operator can rotate and adjust the side frame 5 when placing the PCB boards, so that the side frame 5 does not obstruct the placement of the PCB boards, thereby improving placement efficiency. A first connecting post 9 is fixed on the connecting rod 8, and a second connecting post 10 is fixed on the side of the side frame 5 near the vertical frame. The first connecting post 9 and the second connecting post 10 are arranged parallel to each other. The side frame 5 and the connecting rod 8 are fixedly connected by a connecting collar 11. One end of the connecting collar 11 is fitted onto the first connecting post 9. By rotating the side frame 5, the second connecting post 10 is brought closer to the first connecting post 9, allowing the other end of the connecting collar 11 to be fitted onto the second connecting post 10. The connecting collar 11 limits the first and second connecting posts 9 and 10, thus fixing the side frame 5 to the connecting rod 8. At this time, the angled slot 6 of the side frame 5 abuts against the side of the PCB board, limiting and fixing the side of the PCB board. When placing the PCB board, the side frame 5 can rotate to reserve placement space, making it less likely for the PCB board to bump against the side frame 5 when the operator places the PCB board. After the PCB board is placed, the side frame 5 can be fixed by the connecting collar 11, thereby improving the practicality and flexibility of the placement rack. A pull rod 7 is also fixed on the connecting rod 8. When the placement rack is needed to place the PCB board, the operator can pull the pull rod 7 to move the placement rack, facilitating its transfer.

[0027] Specifically, refer to Figure 3 and Figure 4 The fixing frame 2 includes two vertical rods 21, two connecting rods 22, and a horizontal rod 23. The two ends of the horizontal rod 23 are respectively fixed perpendicularly to one end of each of the two connecting rods 22. The other ends of each of the two connecting rods 22 are rotatably connected to one end of each of the two vertical rods 21. The other ends of each of the two vertical rods 21 are respectively fixedly connected to two vertical supports 101. A second slot 4 is opened at the bottom of the horizontal rod 23. A fixing component 12 is provided on the connecting rod 22, and the connecting rod 22 and the vertical rod 21 are fixed together by the fixing component 12. The fixing component 12 includes a rotating ring 121 and a fixing collar 122. The rotating ring 121 is circularly arranged, and its sidewall is fixed to the end of the connecting rod 22 near the vertical rod 21. A limiting post 13 is fixed to the sidewall of the vertical rod 21, and the rotating ring 121 is sleeved on the limiting post 13, with the rotating ring 121 rotatably connected to the limiting post 13. Rotating the swivel 121 allows the connecting rod 22 to rotate relative to the vertical rod 21. A limiting rod 14 is fixed on the swivel 121. One end of the fixed collar 122 is sleeved on the limiting rod 14. The connecting rods 22 on the two fixed frames 2 rotate towards each other, so that the limiting rod 14 of the swivel 121 on the connecting rod 22 is in a vertical state, so that the other end of the fixed collar 122 can be sleeved on the limiting rod 14 on the swivel 121 of the connecting rod 22 of the other fixed frame 2, thereby achieving the fixation between the swivel 121 and the vertical rod 21, thus keeping the connecting rod 22 and the vertical rod 21 fixed.

[0028] The working principle of this application is as follows: When copper plating is required on the PCB board, the operator removes the connecting collar 11 and the fixing collar 122 from the placement rack. Simply apply force to pull the connecting collar 11 off the first connecting post 9 and the second connecting post 10, and apply force to pull the fixing collar 122 off the limiting rod 14 of the rotating ring 121. Then, rotate the connecting rod 22 relative to the vertical rod 21, causing the two horizontal bars 23 of the two fixing frames 2 to move away from each other and rotate to the outside of the vertical rod 21. Next, rotate the side frames 5 to a vertical position. At this point, the PCB board can be placed above the placement rack, aligned with the horizontal frame 102, without being obstructed by the fixing frames 2 and the side frames 5.

[0029] When the PCB board is placed on the horizontal frame 102, the first slot 3 abuts against the bottom edge of the PCB board, limiting the PCB board's position. The operator then rotates the side frame 5 so that it rotates closer to the side of the PCB board until the wall of the inclined slot 6 of the side frame 5 abuts against the side of the PCB board. Then, the two ends of the connecting collar 11 are respectively fitted onto the first connecting post 9 and the second connecting post 10, limiting the first connecting post 9 and the second connecting post 10, thus fixing the side frame 5 to the connecting rod 8. Next, the connecting rod 22 is rotated so that the horizontal bar 23 rotates to the top of the PCB board and abuts against the top of the PCB board. Then, the fixing collar 122 is fitted onto the limiting post 13 of the vertical bar 21 and the limiting rod 14 of the rotating ring 121, thereby fixing the rotating ring 121 to the vertical bar 21, thus keeping the connecting rod 22 and the vertical bar 21 fixed. At this time, the side frame 5 fixes the side of the PCB board placed on the horizontal frame 102, and the fixing bracket 2 fixes the top of the PCB board placed on the horizontal frame 102, thus ensuring the stability of the PCB board.

[0030] After the PCB board is placed on the mounting rack and secured, the rack is placed in the electroplating tank for copper plating. Because the top and bottom ends of the PCB board are tilted at a certain angle to the vertical direction, it facilitates the escape of air bubbles from the small holes, thus avoiding the problem of non-conductive conductive holes caused by air bubbles. For small-hole PCB boards (hole diameter ≤ 0.25mm), this application significantly reduces the rate of copper-free defects caused by air bubbles, improves product quality and production efficiency, and features a simple structure, economical materials, high efficiency and practicality, and ease of operation, making it highly applicable. It also saves on chemical reagents, thereby reducing processing costs.
