Description

Technical Field

[0001] This utility model belongs to the field of hanging rack technology, specifically relating to a hanging rack for circuit board production. Background Technology

[0002] During the manufacturing process of circuit boards, electroplating is often required. This process typically involves mounting the circuit board on a rack and then immersing it in an electroplating solution.

[0003] Most existing circuit board hangers use clips to clamp and fix the circuit board. For example, Chinese patent application number 202120936922.9 discloses a vertical circuit board hanger, which has the problem that the clamping method remains unchanged and the fixation stability is poor. Utility Model Content

[0004] The purpose of this invention is to provide a circuit board manufacturing rack to solve the problems mentioned in the background art. The circuit board manufacturing rack provided by this invention is characterized by its ease of fixing circuit boards and good stability.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hanging bracket for circuit board production, comprising a frame, a lower clamping part connected to the lower end of the frame, an adjustable upper clamping part provided at the upper end of the frame, the upper clamping part comprising an upper clamping block, a plurality of upper locking blocks connected to the bottom of the upper clamping block, the upper locking blocks being provided with upper locking grooves, the lower clamping part comprising a lower clamping block, a lower locking block corresponding to the upper locking block connected above the lower clamping block, the lower locking block being provided with lower locking grooves.

[0006] To guide the sliding of the upper clamping block, two mounting blocks are connected to the upper end of the frame, and guide rods are connected to the lower part of the mounting blocks. The upper clamping block is slidably connected to the guide rods.

[0007] To limit the sliding stroke of the upper clamping block and prevent it from slipping, and also to adjust the restoring force of the spring, a limit nut is threadedly connected to the lower end of the guide rod.

[0008] In order to make the upper clamping block act on the upper end of the circuit board and cooperate with the lower clamping block to achieve a stable clamping of the circuit board, a spring is further sleeved on the guide rod, and the spring is located between the mounting block and the upper clamping block.

[0009] To facilitate lifting the upper clamping block upwards, a handle is further attached to the top of the upper clamping block.

[0010] In order to position the circuit board during placement and ensure that the upper slot can be accurately locked onto the upper part of the circuit board, the lower end of the upper block is provided with an extension on the rear side of the upper slot.

[0011] To facilitate the quick insertion of the circuit board, the front side of the upper slot and both sides of the lower slot are further provided with bevels.

[0012] To facilitate the adjustment of the position of the lower clamping block and thus make it suitable for circuit boards of different specifications to a certain extent, the lower end of the frame is further provided with two waist grooves, and the lower clamping block is connected to the frame by bolts passing through the waist grooves.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model supports the lower end of the circuit board by using a lower clamping block, limits the lower end of the circuit board by using a lower slot, and limits the upper end of the circuit board by using an adjustable upper clamping part.

It has the characteristics of simple fixing method and good fixing effect.

[0015] 2. This utility model utilizes the restoring force of the spring to act on the upper clamping block, so that the upper clamping block acts on the upper end of the circuit board, and cooperates with the lower clamping block to achieve a stable clamping of the circuit board.

[0016] 3. The lower end of the upper card block of this utility model is provided with an extension at the rear side of the upper card slot. When placing the circuit board, the extension is used to position the circuit board to ensure that the upper card slot can be accurately locked on the upper end of the circuit board.

[0017] 4. The lower end of the frame of this utility model is provided with two waist grooves. The lower clamping block is connected to the frame by bolts passing through the waist grooves, which facilitates the adjustment of the position of the lower clamping block, so that it can be used for circuit boards of different specifications to a certain extent.

Compared with the prior art of fixing the circuit board with clamps, this utility model only needs to move the upper clamping part 2 upward to put the lower end of the circuit board into the lower slot 33, and then reset the upper clamping part 2 to complete the fixing of the circuit board. It has the characteristics of simple fixing method and good fixing effect.

[0027] Specifically, the upper end of the frame 1 is connected to two mounting blocks 101, and the lower part of the mounting blocks 101 is connected to a guide rod 102. The upper clamping block 21 is slidably connected to the guide rod 102.

[0028] By adopting the above technical solution, the sliding of the upper clamping block 21 is guided.

[0029] Specifically, the lower end of the guide rod 102 is threadedly connected to a limit nut 103.

[0030] By adopting the above technical solution, the sliding stroke of the upper clamping block 21 is limited to prevent the upper clamping block 21 from slipping out, and it can also be used to adjust the restoring force of the spring 4.

[0031] Specifically, a spring 4 is fitted on the guide rod 102, and the spring 4 is located between the mounting block 101 and the upper clamping block 21.

[0032] By adopting the above technical solution, the restoring force of the spring 4 acts on the upper clamping block 21, so that the upper clamping block 21 acts on the upper end of the circuit board, and cooperates with the lower clamping block 31 to achieve a stable clamping of the circuit board.

[0033] Specifically, a handle 25 is connected to the top of the upper clamping block 21.

[0034] By adopting the above technical solution, it is easy to lift the upper clamping block 21 upward.

[0035] Example 2

[0036] The difference between this embodiment and embodiment 1 is that, specifically, the lower end of the upper card block 22 is provided with an extension 23 located on the rear side of the upper card slot 24.

[0037] By adopting the above technical solution, when placing the circuit board, the extension 23 positions the circuit board, ensuring that the upper slot 24 can be accurately locked onto the upper end of the circuit board.

[0043] By adopting the above technical solution, it is easy to adjust the position of the lower clamping block 31, so that it can be applied to circuit boards of different specifications to a certain extent.

[0044] In summary, this invention supports the lower end of the circuit board using the lower clamping block 31, limits the lower end of the circuit board using the lower slot 33, and limits the upper end of the circuit board using the adjustable upper clamping part 2. Compared with the prior art method of fixing the circuit board with clamps, this invention only requires moving the upper clamping part 2 upwards to place the lower end of the circuit board into the lower slot 33, and then resetting the upper clamping part 2 to complete the fixing of the circuit board. It has the advantages of simple fixing method and good fixing effect. This invention utilizes the restoring force of the spring 4 to act on the upper clamping block 21, so that the upper clamping block 21 acts on the upper end of the circuit board, and cooperates with the lower clamping block 31 to achieve a stable clamping of the circuit board. The lower end of the upper slot 22 of this invention has an extension part 23 located behind the upper slot 24. When placing the circuit board, the extension part 23 positions the circuit board to ensure that the upper slot 24 can accurately clamp the upper end of the circuit board.
