Description

TECHNICAL FIELD

[0001] The utility model relates to a circuit board placing rack. BACKGROUND

[0002] Printed circuit board is also called PCB (Printed Circuit Board), which is mainly composed of pads, vias, mounting holes, wires, components, connectors, fillings and electrical boundaries. The development of electronic industry, especially the development of microelectronic technology, makes the application of integrated circuits more and more extensive. Therefore, the circuit board plays an important role in electronic equipment. Its stability directly affects the performance of electronic equipment. Thus, new requirements are constantly put forward for the manufacturing process and precision of the circuit board.

[0003] The types of printed circuit board have developed from single-sided and double-sided boards to multi-layer boards, rigid and flexible boards, and the printed lines are becoming thinner and thinner. However, the most widely used are single-sided and double-sided printed circuit boards.

[0004] During the manufacturing process of printed circuit board, it needs to go through multiple processes. After each process, the circuit board needs to be placed and stored temporarily to prepare for the next process of processing and manufacturing. That is, it needs to be able to temporarily store and transport the circuit board, and the circuit board needs to be dried after processing. Currently, the stability of the circuit board during transportation is poor. Generally, only the bottom is clamped, and the top of the circuit board is easy to shake and collide with the adjacent one, causing damage. Therefore, it needs to be improved. UTILITY MODEL CONTENT

[0005] In view of the shortcomings of the prior art, the technical problem to be solved by the utility model is to provide a circuit board placing rack which is not only reasonable in structure, but also stable and convenient.

[0006] In order to solve the above technical problems, the technical scheme of the utility model is as follows: a circuit board placing rack, comprising a plug-in seat, a plurality of plug-in slots for plugging in circuit boards are recessed on the plug-in seat at intervals along the length direction, side pressing assemblies are symmetrically arranged on both sides of the plug-in slot, the side pressing assembly comprises a turnover block, a rotating rod is transversely arranged and rotatably connected in the turnover block, a connecting rod is fixedly arranged on the rotating rod, a top plate is hingedly connected to the end of the connecting rod, a torsion spring is coaxially sleeved on the rotating rod to make the connecting rod turn over and close to each other to clamp the circuit board, the two ends of the torsion spring abut against the turnover block, and the lower end of the turnover block is rotatably connected to the plug-in seat; a positioning groove is recessed inward at two opposite ends of the plug-in seat to cooperate with the plug-in locking of the supporting frame.

[0007] Further, the lower end of the turnover block is rotatably connected to the fixed block through a longitudinally extending rotating shaft, and the fixed block is fixedly connected to the plug-in seat.

[0008] Furthermore, both the rotating shaft and the fixing block have transverse through-holes for inserting and limiting the pin shaft laterally.

[0009] Furthermore, the slot is provided with longitudinally symmetrical clamping plates, and several springs are arranged in an array between the clamping plates and the inner wall of the slot. The top of each clamping plate extends out of the slot and extends in an arc shape in opposite directions to form a flared mouth.

[0010] Furthermore, the inner sides of the clamping plate and the inner sides of the top plate are both padded with soft pads to facilitate contact with the circuit board.

[0011] Furthermore, the receiving frame is provided with several bearings at intervals to support the plug-in seat. Each bearing protrudes towards the other and has a longitudinal groove at two opposite corners. A T-shaped plug is slidably connected in the longitudinal groove to cooperate with the insertion of the positioning groove.

[0012] Furthermore, each of the two longitudinal top ends of the connector is fixed with a lifting handle, and each lifting handle is provided with a gripping groove for easy holding. The upper end of the support is recessed with a limiting groove for supporting the lifting handle.

[0013] Compared with the prior art, the present invention has the following advantages: by setting the side pressure component in conjunction with the clamping plate, a stable temporary storage and transportation environment for the circuit board can be provided, effectively avoiding the problem of the circuit board shaking at the top and colliding with adjacent components, thus preventing damage from bumps and knocks.

[0014] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. Attached Figure Description
