Description

Technical Field

[0001] This invention relates to the field of circuit board technology, and more specifically to a PCB board loading and clamping device. Background Technology

[0002] PCB (Printed Circuit Board) is an important electronic component. It serves as the support for electronic components and the carrier for their electrical interconnection. Because it is manufactured using electronic printing techniques, it is called a "printed" circuit board.

[0003] During the production and storage of PCBs, corresponding material frames are needed to separate and store the PCB boards. Since PCBs are generally thin sheet structures, there is a certain gap between the material placement space of the existing PCB material frames and the PCB boards. The PCB boards are prone to shaking when placed in the gap, which can cause damage to the PCB boards. At the same time, the existing material frames cannot hold the PCB boards firmly, making it difficult to place the thin sheet structure of the PCB boards relatively stably in the material frames. Summary of the Invention

[0004] To solve the above-mentioned technical problems, a PCB board loading and clamping device is provided.

[0005] To achieve the above objectives, the following solution is provided: A PCB board loading and clamping device includes a material frame and several clamping components. Several supporting horizontal plates and clamping rails are installed on both sides of the material frame. The supporting horizontal plates are fixedly installed on the sides of the material frame, and the clamping rails are fixedly installed on the sides of the material frame via the supporting horizontal plates. The clamping rails on the left and right sides of the material frame correspond one-to-one. Clamping components are installed on the sides of the clamping rails and are movably installed on the supporting horizontal plates. Each clamping component includes a drive rod and several clamping modules. The drive rod is slidably installed on the supporting horizontal plates and drives... Several clamping modules are installed on the rod. The clamping modules are installed between the drive rod and the support cross plate. The clamping module includes a fixed seat, a connecting rod, a clamping block and an elastic element. The fixed seat is fixedly installed on the drive rod. The fixed seat is rotatably connected to one end of the connecting rod through a rotating shaft. The other end of the connecting rod is rotatably connected to the clamping block through a rotating shaft. The end of the clamping block away from the connecting rod is rotatably connected to the support cross plate through a rotating shaft. The clamping block is inserted into the rail. The end of the clamping block is connected to one end of the elastic element. The other end of the elastic element is connected to the support cross plate, and the connection part between the elastic element and the support cross plate is located on the side of the rail away from the clamping block.

[0006] Furthermore, the support plate is evenly provided with several sliding grooves, and the drive rod is inserted into the sliding grooves.

[0007] Furthermore, the rail has an opening on the side near the clamping block, and the clamping block is inserted into the rail along the opening.

[0008] Furthermore, a pressure block is installed on the top of the drive rod.

[0009] Furthermore, a card plate is provided at the bottom of the material frame, and several card slots are evenly opened on the card plate, the positions of which are adapted to the card rail.

[0010] Furthermore, the slot has a "V" shaped structure.

[0011] Furthermore, a guide plate is provided on the top of the rail.

[0012] Furthermore, the elastic element is a spring.

[0013] The working principle and advantages of this invention are as follows: This PCB board loading and clamping device places the PCB in the rails on both sides of the material frame, and then uses the clamping plate at the bottom of the material frame to initially position the PCB. Subsequently, the clamping module installed on the side of the rail clamps the PCB and fixes it in the rail, which can prevent the PCB from shaking in the rail and reduce the possibility of damage to the PCB due to shaking and impact with the material frame. It can also firmly fix the PCB in the material frame and effectively prevent the PCB from falling off the rail. Attached Figure Description

[0020] The following detailed explanation illustrates the specific implementation methods:

[0021] like Figures 1 to 4 As shown:

[0022] A PCB board loading and clamping device includes a material frame 1 and several clamping components 2. The material frame 1 is used to load PCB boards, and the clamping components 2 are used to clamp and fix the PCB boards in the material frame 1. Multiple support plates 13 are horizontally mounted on both sides of the material frame 1. The support plates 13 are used to mount the clamping components 2 and rails 14. The rails 14 are vertically fixed on the support plates 13 on both sides of the material frame 1. The rails 14 on both sides of the material frame correspond one-to-one, allowing the PCB board to be smoothly placed between the two rails 14. The clamping components 2 are mounted on one side of the rails 14, with one rail 14 corresponding to one clamping component 2. The clamping components 2 include a drive rod 22 and multiple clamping modules mounted on the drive rod 22. Located between the support plate 13 and the drive rod 22, the drive rod 22 is slidably installed at each support plate 13, allowing the drive rod 22 to move up and down on the side of the material frame 1. The clamping module consists of a fixed base 23, a connecting rod 24, a clamping block 25, and an elastic element 26. The fixed base 23 is fixedly installed on the drive rod 22 and is used to install the connecting rod 24. One end of the connecting rod 24 is rotatably installed on the fixed base 23, and the other end of the connecting rod 24 is rotatably connected to the clamping block 25, so that when the drive rod 22 presses down, it can drive the clamping block 25 to move through the connecting rod 24. The elastic element 26 is installed between the clamping block 25 and the support plate 13. Under the action of the elastic element 26, the clamping block 25 is pushed and pulled into the rail 14.

[0023] A number of sliding grooves 16 are evenly arranged on the support plate 13. The drive rod 22 is inserted into the sliding groove 16, and the sliding groove 16 is used for the directional movement of the drive rod 22.

[0024] An opening 17 is provided on the side of the rail 14 near the clamping block 25. The opening 17 allows the clamping block 25 to be smoothly inserted into the rail 14, so that the clamping block 25 can hold the PCB board in the rail 14.

[0025] The top of the drive rod 22 is equipped with a pressure block 21 for connection with the corresponding drive device. The drive device adopts existing mechanical drive devices, such as cylinders, hydraulic cylinders, push rods, etc. Users can configure them as needed, which will not be described again. The drive device presses the pressure block, thereby pressing the drive rod 22 to move.

[0026] The bottom of the material frame 1 is provided with a card plate 11, and several card slots 12 are evenly opened on the card plate 11. The card slots 12 are positioned to match the card rails 14. The card slots 12 have a "V" shaped structure, so that the PCB board is positioned by the card rails 14 on both sides of the material frame 1 and the card slots 12 of the card plate 11 at the bottom of the material frame 1.

[0027] The top of the rail 14 is provided with a guide plate 15, which makes it easier to insert the PCB board into the slot 12.

[0028] Elastic components are commonly used elastic mechanisms such as springs that can extend and retract.

[0029] The specific implementation process is as follows:

[0030] When using this PCB board loading clamping device, the corresponding driving device first presses down the pressure block 21, and then pushes down the driving rod 22. During the downward pressing process, the driving rod 22 drives the connecting rod 24 to move through the fixed seat 23. The connecting rod 24 drives the clamping block 25 to swing, so that the clamping block 25 separates from the rail 14 from the opening 17 at the rail 14. The elastic member 26 is stretched inward. Then, the PCB board can be inserted into the rail 14 through the guide plate 15 at the top of the rail 14, so that the bottom of the PCB board enters the corresponding slot 12. Then, the driving device releases the corresponding clamping module, and the corresponding clamping module is reset under the elastic force of the elastic member 26, so that the clamping block 25 clamps the PCB board in the rail 14 under the action of the elastic member 26.

[0031] This PCB board loading and clamping device places the PCB board in the rails 14 on both sides of the material frame 1. The PCB board is initially positioned by the clamping plate 11 at the bottom of the material frame 1. Then, the clamping module installed on the side of the rail 14 clamps and fixes the PCB board in the rail 14. This prevents the PCB board from shaking in the rail 14, reduces the possibility of damage to the PCB board due to shaking and impact with the material frame 1, and firmly fixes the PCB board in the material frame 1, effectively preventing the PCB board from falling off the rail 14.
