Description

Technical Field

[0001] The invention relates to the field of circuit board processing, in particular to a circuit board plug-in rack. Background Art

[0002] Printed circuit boards are important electronic components and are the supporting parts of electrical components. The production of circuit boards generally has the following processes: computer drilling - machine grinding - copper deposition - circuit pattern transfer - electroplating - etching - corrosion inspection - solder mask ink - characters - shape - V-CUT - testing - anti-oxidation - inspection - packaging - shipment, etc. When the circuit board is transported between various processes, it is necessary to fix the circuit board on the plug-in board rack. Patent application number: CN202321913932.6 discloses a circuit board plug-in board rack, including a support plate, the upper end of the support plate is evenly fixed with a support card slot, one side of the upper end of the support plate is also fixed with a positioning plate, the positioning plate is evenly fixed with a positioning card slot, and the other side of the upper end of the support plate is also provided with a limit plate. The circuit board to be placed is fixed on the plug-in board rack, the bottom of the circuit board is separated by the support card slot on the support plate, and the edge on one side of the circuit board is separated by the positioning card slot on the positioning plate. However, after this type of plug-in board rack is used, the circuit board is fixed on the plug-in board rack, there is no misalignment between the circuit boards, and it is very difficult to remove the circuit board.

[0003] The present invention is proposed in view of the deficiencies in the prior art. Summary of the invention

[0004] The purpose of the present invention is to overcome the above-mentioned disadvantages of the prior art and provide a circuit board plug-in rack.

[0005] The present invention can be implemented by the following technical solutions:

[0006] The cam is provided with a plurality of support plates, the support plates having two ends respectively connected to the support plates, the support plates having a plurality of support plates respectively connected to the support plates, and the support plates are provided with a plurality of support plates respectively connected to the support plates. When the circuit board is fixed, the circuit board is placed between the two positioning rods, and the bottom of the circuit board is supported by the support plate. After the circuit board is placed, the handle at the end of the screw is turned. Since the screw is threadedly connected to the threaded tube, the bottom of the limit plate is set on the card block and is slidably connected with the card block. When the screw rotates, the threaded tube moves in the direction of the screw, and the card block moves in the direction of the screw. When the card block moves, the card block pushes each limit plate to move, and the limit plate pushes the circuit board to move. The limit plate fixes the circuit board on the positioning rods to fix each circuit board. After the circuit board is transferred to the next process, the screw is rotated in the opposite direction, the limit plate moves, and the limit plate is separated from the circuit board, and the circuit board is removed from between the positioning rods. Moreover, since the support plate is tilted, after the circuit board is placed on the support plate, there is a height difference between the tops of adjacent circuit boards, which is convenient for fingers to hold the circuit board from both sides of the circuit board and remove the circuit board.

[0007] Preferably, a plurality of sliding rods are fixed on the clamping block, and the sliding rods pass through the base and are slidably connected to the base.

[0008] Preferably, a handle is fixed on the support plate, so as to facilitate the transfer of the plug-in board rack.

[0009] Compared with the prior art, the present invention has the following advantages:

[0010] The support plate is tilted, and after the circuit boards are placed on the support plate, there is a height difference between the tops of adjacent circuit boards, which makes it convenient for fingers to hold and remove the circuit boards from both sides of the circuit boards.
