Description

Technical Field

[0001] This utility model relates to the field of nickel-gold plating technology for circuit boards, and specifically to a clamping structure for nickel-gold plating of circuit boards. Background Technology

[0002] A circuit board, also known as a printed circuit board, is a substrate used to support and connect electronic components. It is made of an insulating substrate material with conductive tracks, holes, and metallized holes. These components are used to connect electronic components such as resistors, capacitors, diodes, transistors, and integrated circuits.

[0003] In the prior art, a clamping table is used to repair nickel-gold plating on circuit boards. The top of the circuit board is placed on a support plate on the clamping table, and then a support rod is used to support the bottom of the circuit board. The support rod is fixed to the clamping table with bolts, thereby achieving the effect of clamping and fixing the circuit board.

[0004] However, when the circuit board is clamped and fixed on the clamping table, the lack of support and fixing on both sides of the circuit board causes lateral displacement of the circuit board during nickel-gold plating, thus affecting the stability of the nickel-gold plating process. Utility Model Content

[0005] The purpose of this utility model is to provide a nickel-gold plating clamping structure for circuit boards, so as to solve the technical problem that when circuit boards are clamped and fixed on the clamping table in the prior art, the two sides of the circuit board lack a supporting and fixing function, which causes the circuit board to shift laterally during nickel-gold plating, thereby affecting the stability of the nickel-gold plating process.

[0006] The technical problem to be solved by this utility model can be achieved through the following technical solution:

[0007] The circuit board nickel-gold plating clamping structure includes:

[0008] The workbench has two sets of side plates fixedly connected to its top, with the two sets of side plates located on both sides of the workbench.

[0009] A support plate is provided on the top of the workbench. The two sides of the support plate are respectively hinged to the side plates. A support groove is provided on the side end of the support plate. A support plate is slidably connected to the inner wall of the support plate.

[0010] A support plate is provided on the top of the workbench. A screw is fixedly connected to the side end of the support plate, and a suction cup is fixedly connected to the end of the support plate away from the screw. An adjustment hole is provided through the side end of the support plate, and the screw is threaded to the inner wall of the adjustment hole. An air hole is provided through the suction cup.

[0011] As a further embodiment of this utility model: two sets of support columns are provided between the support plate and the workbench. The two sets of support columns are located on both sides of the support plate, the bottom end of the support column is fixedly connected to the workbench, and the top end of the support column is abutting and connected to the support plate.

[0012] As a further embodiment of this utility model: slide seats are fixedly connected to both ends of the support plate, a support groove is provided at one end of the support plate near the side plate, a sliding groove is provided inside the support plate, and the slide seat is slidably connected to the inner wall of the sliding groove.

[0013] As a further embodiment of this utility model: the inner wall of the groove is engaged with the slide block.

[0014] As a further embodiment of this utility model: a fixing hole is provided inside the slide block, and a bolt is threadedly connected to the inner wall of the fixing hole, with the side end of the bolt abutting against the support plate.

[0015] As a further embodiment of this utility model, the cross-section of the supporting groove is triangular.

[0016] As a further embodiment of this utility model: the workbench is fixedly connected to a support frame for supporting the support plate, and the two sets of support frames are located on both sides of the workbench respectively.

[0017] As a further embodiment of this utility model: a rotating groove is provided inside the side plate, and a rotating seat is rotatably connected to the inner wall of the rotating groove, and the side end of the rotating seat is fixedly connected to the support plate.

[0018] As a further embodiment of this utility model: the rotating seat has a positioning groove through the side plate, and the positioning seat is connected to the inner wall of the positioning groove.

[0019] As a further embodiment of this utility model: a connecting rod is fixedly connected to the side end of the positioning seat, a connecting plate is fixedly connected to the side end of the connecting rod, a spring is provided between the connecting plate and the side plate, the two ends of the spring are fixedly connected to the connecting plate and the side plate respectively, and a fixing groove is provided on the side end of the side plate.

[0020] The beneficial effects of this utility model are:

[0021] 1. Hold one end of the circuit board against the inner wall of the support groove, then slide the support plate along the inner wall of the support plate to hold the circuit board. The side end of the circuit board and the side end of the support plate are also held together, thereby achieving three-dimensional positioning of the circuit board. Then, rotate the screw, which moves along the inner wall of the adjustment hole. The screw, along with the support plate, holds the side end of the circuit board. When the screw stops rotating, the threaded connection between the screw and the inner wall of the adjustment hole provides a fixing effect, which is transmitted to the circuit board through the support plate. This achieves the holding and fixing of the circuit board around its perimeter, preventing the circuit board from shifting during nickel-gold plating.

[0022] 2. Rubber pads can be attached to the inner wall of the support groove to prevent wear on the edges of the circuit board when the support plate supports it. When the suction cup fixed to the side of the support plate supports the circuit board, the air between the suction cup and the circuit board is discharged through the air hole, thereby achieving the effect of suction cup adsorbing the circuit board. At the same time, the suction cup is plastic, which can prevent the support plate from wearing on the circuit board when it supports it. Attached Figure Description

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0035] like Figures 1-9 As shown, the circuit board nickel-gold plated clamping structure includes: a worktable 1, a support plate 3, and a support plate 8.

[0036] Two sets of side plates 7 are fixedly connected to the top of the workbench 1, and the two sets of side plates 7 are located on both sides of the workbench 1. The support plate 3 is set on the top of the workbench 1, and the two sides of the support plate 3 are hinged to the side plates 7 respectively. The side end of the support plate 3 has a support groove 12. The inner wall of the support plate 3 is slidably connected to a support plate 10. The support plate 8 is set on the top of the workbench 1, and the side end of the support plate 8 is fixedly connected to a screw 5. The end of the support plate 8 away from the screw 5 is fixedly connected to a suction cup 9. The side end of the support plate 3 has a through-hole 13. The screw 5 is threaded to the inner wall of the adjustment hole 13. The suction cup 9 has an air hole 14 through its interior. One end of the circuit board is held against the inner wall of the support groove 12, and then the support plate 10 slides along the inner wall of the support plate 3 to hold the circuit board. The side end of the circuit board is held against the side end of the support plate 3, thereby achieving positioning of the circuit board in three directions. Then, the screw 5 is rotated and moves along the inner wall of the adjustment hole 13. The screw 5, along with the support plate 8, holds the side end of the circuit board. When the screw 5 stops rotating, the threaded connection between the screw 5 and the inner wall of the adjustment hole 13 provides a fixing effect, which is transmitted to the circuit board through the support plate 8, thereby achieving the holding and fixing of the circuit board around the perimeter, and preventing the circuit board from shifting during nickel-gold plating.

[0037] A rubber pad can be attached to the inner wall of the support groove 12 to prevent the support plate 3 from abrading the edges of the circuit board. When the suction cup 9 fixed to the side of the support plate 8 abrades the circuit board, the air between the suction cup 9 and the circuit board is discharged from the air hole 14, thereby achieving the effect of suction cup 9 adsorbing the circuit board. At the same time, the suction cup 9 is plastic, which can prevent the support plate 8 from abrading the circuit board when it abrades the circuit board.

[0038] In some specific implementations, two sets of support columns 2 are provided between the support plate 3 and the workbench 1. The two sets of support columns 2 are located on both sides of the support plate 3. The bottom end of the support column 2 is fixedly connected to the workbench 1, and the top end of the support column 2 is abutted to the support plate 3. When the support plate 3 and the workbench 1 are placed parallel to each other, and then the circuit board is installed on the support plate 3, the support column 2 abuts against the bottom end of the support plate 3, and the support column 2 provides support for the support plate 3, thereby ensuring that the support plate 3 and the workbench 1 are parallel.

[0039] In some specific embodiments, the support plate 10 is fixedly connected to slide blocks 15 at both ends. The support plate 10 has a support groove 12 at one end near the side plate 7. The support plate 3 has a sliding groove 11 inside. The slide block 15 is slidably connected to the inner wall of the sliding groove 11. The inner wall of the sliding groove 11 is engaged with the slide block 15. When the support plate 10 supports the circuit board, the circuit board and the inner wall of the support groove 12 support each other. The support plate 10 slides along the inner wall of the sliding groove 11 with the slide block 15. The engagement of the inner wall of the sliding groove 11 with the slide block 15 provides a limiting support for the support plate 10.

[0040] In some specific implementations, the slide block 15 has a fixing hole 16 inside, and a bolt 4 is threadedly connected to the inner wall of the fixing hole 16. The side end of the bolt 4 is abutted and connected to the support plate 3. When the support plate 10 abuts against the circuit board, the bolt 4 is rotated and threaded into the fixing hole 16. When the bolt 4 and the support plate 3 abut against each other, the slide block 15 is fixed.

[0041] In some specific embodiments, the cross-section of the abutment groove 12 is triangular. The shape of the abutment groove 12 can ensure that the inner wall of the abutment groove 12 can abut against the upper and lower edges of the circuit board, thereby avoiding the phenomenon of the circuit board shifting in the direction of the vertical axis of the support plate 10.

[0042] In some specific implementations, the workbench 1 is fixedly connected to a support frame 6 for supporting the support plate 3. Two sets of support frames 6 are located on both sides of the workbench 1. When the circuit board is installed on the support plate 3, the support plate 3 is rotated. The two ends of the support plate 3 rotate along the axis of the side plate 7. The support plate 3 rotates with the circuit board to the support frame 6, and the support frame 6 supports the support plate 3.

[0043] In some specific embodiments, a rotating groove 17 is provided inside the side plate 7, and a rotating seat 18 is rotatably connected to the inner wall of the rotating groove 17. The side end of the rotating seat 18 is fixedly connected to the support plate 3. The rotating seat 18 passes through the side plate 7 and has a positioning groove 19. A positioning seat 20 is abutted against the inner wall of the positioning groove 19. A connecting rod 21 is fixedly connected to the side end of the positioning seat 20, and a connecting plate 23 is fixedly connected to the side end of the connecting rod 21. A spring 22 is provided between the connecting plate 23 and the side plate 7. The two ends of the spring 22 are fixedly connected to the connecting plate 23 and the side plate 7, respectively. A fixing groove 24 is provided on the side end of the side plate 7. When the support plate 3 rotates, the support plate 3 carries the rotating seat 18 along the rotating groove. When the inner wall of 17 rotates, and the support plate 3 and the side plate 7 abut against each other, the positioning seat 20 passes through the inner wall of the fixing groove 24 and the positioning groove 19 and abuts against each other. The positioning seat 20 abuts against the rotating seat 18 and thus positions the support plate 3. The spring 22 pulls the connecting rod 21 by pulling the connecting plate 23. The connecting rod 21 transmits the elastic tension of the spring 22 to the positioning seat 20, thereby ensuring that the positioning seat 20 always abuts against the inner wall of the positioning groove 19. When the support plate 3 is reset, the abutment of the positioning seat 20 against the inner wall of the positioning groove 19 is released. Then, when the support plate 3 and the support column 2 abut against each other, the positioning seat 20 passes through the positioning groove 19 opened in the side plate 7 and the inner wall of the positioning groove 19 opened in the rotating seat 18 and abuts against each other.

[0044] The foregoing has described several embodiments of this utility model in detail, but these embodiments are not limited thereto and should not be considered as limiting the scope of this utility model. All equivalent changes and improvements made within the scope of the claims of this utility model should still fall within the patent coverage of this utility model.
