Description

Technical Field

[0001] This application relates to the field of PCB board transfer technology, and in particular to a PCB board transfer device. Background Technology

[0002] PCB, or Printed Circuit Board, is an important electronic component. It serves as the support for electronic components and the carrier for their electrical interconnections. In the PCB manufacturing process, copper plating and pickling are two key steps, typically requiring the transfer of PCBs between different production lines. As PCBs become increasingly dense and thinner, the requirements for protection and efficiency during PCB transfer are becoming increasingly stringent.

[0003] In related technologies, the following methods are generally used in the transfer process between PCB board processes: 1. Manual handling, where operators directly carry the PCB boards by hand, which is highly flexible; 2. Using simple trolleys for transfer, such as using ordinary flatbed trolleys to stack multiple PCB boards for transfer, which has a lower cost; 3. Using automated conveyor belt systems, which achieve continuous transfer through conveyor belts, which is highly efficient.

[0004] In practical use, it was found that manual handling and simple trolleys lacked effective measures to fix and protect PCB boards, which could easily lead to products colliding or stacking, making it difficult to meet the quality requirements of PCB boards; conveyor belt transportation could not meet the requirement that PCB boards need to be vertically inserted after electroplating, and the equipment was complex and had high maintenance costs. Utility Model Content

[0005] In order to improve the quality of PCB boards and meet the vertical insertion requirements after PCB board electroplating, this application provides a PCB board transfer device, which solves the problem of mutual collision and stacking of PCB boards during the transfer process, meets the vertical insertion requirements after PCB board electroplating, and improves the transfer quality of PCB boards.

[0006] The PCB board transfer device provided in this application adopts the following technical solution: A PCB board transfer device includes a box with an open top and multiple rollers at the bottom. A transfer groove is provided on the top of the box, and limit plates are provided on opposite side walls of the transfer groove. A slot is provided on the side of the two limit plates that are close to each other in the vertical direction. Multiple slots are provided at equal intervals along the horizontal direction of the limit plates, and the two edges of the PCB board are inserted into the slots.

[0007] By adopting the above technical solution, the PCB board edge is positioned by the slot, so that each PCB board is independently fixed and maintains a gap with the adjacent PCB boards, which effectively reduces the problem of mutual collision and stacking of PCB boards during transportation and improves the transportation quality of PCB boards. At the same time, the vertical insertion of PCB boards into the slot is conducive to meeting the processing requirements after PCB board electroplating and has low cost. By pushing the box, the entire device can be moved smoothly by the rollers to complete the PCB board transportation process.

[0008] Optionally, a wastewater collection tank is provided at the bottom of the box, the wastewater collection tank is connected to the transfer tank, a support plate is provided on the inner wall of the wastewater collection tank, the PCB board is located on the top of the support plate, and multiple through holes are provided on the support plate.

[0009] By adopting the above technical solution, the support plate provides support for the PCB board, and the residual wastewater attached to the surface of the PCB board flows into the wastewater collection tank through the through holes, reducing the accumulation at the bottom of the PCB board and also enabling unified cleaning of the wastewater in the wastewater collection tank.

[0010] Optionally, a drain pipe is connected to the outer wall of the wastewater collection tank, and a control valve is installed on the drain pipe.

[0011] By adopting the above technical solution, the opening and closing of the drain pipe is controlled by a control valve. Operators can flexibly open the control valve according to the amount of wastewater in the wastewater collection tank, which facilitates direct and directional discharge of wastewater without the need to move the tank, effectively reducing the intensity of operation.

[0012] Optionally, a handle is provided on the side wall of the box.

[0013] By adopting the above technical solution, the box can be pushed by holding the handle. Compared with directly pushing the top and edge of the box, it is easier for the operator to apply horizontal pushing force, and the pushing process is time-saving and labor-saving.

[0014] Optionally, baffles are provided on the top of both sides of the box, with the two baffles located on both sides of the handle.

[0015] By adopting the above technical solution, the baffle can reduce the possibility of other operators coming into contact with the PCB board from above the housing, thereby reducing the risk to personnel and deformation of the PCB board, which helps to improve the operational safety of the device.

[0016] Optionally, a storage box is provided on the side wall of the box, and the storage box is located below the handle.

[0017] By adopting the above technical solution, the storage box is convenient for storing some auxiliary tools, which can be easily accessed by operators during the pushing process without having to go back and forth to retrieve them, thus improving work efficiency.

[0018] Optionally, the roller is configured as a swivel wheel, and a braking device is installed on the swivel wheel.

[0019] By adopting the above technical solution, the casters will automatically adjust the orientation of the box according to the direction of the force, so that the box moves smoothly. At the same time, the braking device can temporarily or permanently fix the device, improving the mobility of the device.

[0020] Optionally, a rubber plate is provided on the limiting plate.

[0021] By adopting the above technical solution, when the operator inserts the two sides of the PCB board into the slot of the limiting plate, the inner wall of the rubber plate undergoes slight elastic deformation due to the compression of the PCB board, so that the inner wall of the slot fits tightly with the edge of the PCB board, which can reduce the relative sliding between the PCB board and the slot and make the placement of the PCB board more stable.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. By positioning the PCB board edges through slots, each PCB board is independently fixed and maintains a gap with adjacent PCB boards, effectively reducing the problem of PCB boards colliding and stacking during transportation and improving the quality of PCB boards; at the same time, the vertical insertion of PCB boards into the slots is beneficial to meeting the processing requirements after PCB board electroplating and is low in cost; by pushing the box, the entire device can be moved smoothly by the rollers to complete the PCB board transportation process. 2. The support plate provides support for the PCB board. Residual wastewater adhering to the surface of the PCB board flows into the wastewater collection tank through the through holes, reducing the accumulation at the bottom of the PCB board and also enabling unified cleaning of the wastewater in the wastewater collection tank; 3. When the operator inserts the two sides of the PCB board into the slots of the limiting plate, the inner wall of the rubber undergoes slight elastic deformation due to the compression of the PCB board, which makes the inner wall of the slot fit tightly with the edge of the PCB board, reducing the relative sliding between the PCB board and the slot, and making the placement of the PCB board more stable.

[0025] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0026] This application discloses a PCB board transfer device, referring to... Figure 1 and Figure 2 The device includes a box 1, which is rectangular in shape and has an open top. Rollers 2 are installed at the four corners of the bottom of the box 1 for easy movement. A transfer groove 3 for accommodating PCB boards is provided inside the upper part of the box 1. Limiting plates 4 are fixedly connected to the opposite side walls of the transfer groove 3 and extend along the height direction of the box 1. A slot 5 is provided vertically on the side of the two limiting plates 4 that are close to each other. Multiple slots 5 are provided at equal intervals along the horizontal direction of the limiting plates 4. In this embodiment, there are a total of 15 slots 5, which can insert 15 PCB boards at one time.

[0027] After the operator vertically inserts the electroplated PCB board into the slot 5, the position of the PCB board is fixed by the slot 5 on the limiting plate 4, and the limiting plate 4 between adjacent slots 5 ensures that each PCB board maintains a distance, effectively reducing the problem of PCB boards colliding and overlapping; the vertical insertion method is adapted to the process requirements of the electroplated PCB board; 15 PCB boards can be transferred at a time, which effectively improves the transfer efficiency; this structure is simple, reliable, and low in cost, and also effectively improves the transfer quality of PCB boards.

[0028] Reference Figure 1 and Figure 2 The lower part of the box 1 has a wastewater collection tank 6, which is located below the transfer tank 3 and is connected to the transfer tank 3. A support plate 7 is fixed to the inner wall of the box 1 by welding. The support plate 7 is perpendicular to the limiting plate 4, and the limiting plate 4 and the PCB board are located above the support plate 7. The support plate 7 separates the transfer tank 3 and the wastewater collection tank 6. The support plate 7 has multiple through holes 8. After the PCB board is positioned by inserting it into the slots 5 on both sides, the bottom of the PCB board abuts against the top of the support plate 7. The support plate 7 provides vertical support for the PCB board. At the same time, the wastewater on the PCB board after electroplating flows into the wastewater collection tank 6 through the through holes 8, which facilitates centralized treatment of wastewater.

[0029] Reference Figure 1 and Figure 2 A drain pipe 9 is connected to the bottom of the side wall of the housing 1. The drain pipe 9 is connected to the wastewater collection tank 6. A control valve 10 is installed on the drain pipe 9. When it is necessary to clean the wastewater collection tank 6, the control valve 10 is opened to discharge the wastewater in the wastewater collection tank 6 from the drain pipe 9, thereby reducing the impact of wastewater on the PCB board.

[0030] Reference Figure 1A handle 11 is inclinedly provided on the outer side wall of the box 1. The handle 11 is U-shaped and both ends of the handle 11 are welded and fixed to the side wall of the box 1. By holding the handle 11, the operator can maintain a natural standing posture, which makes it easy to push the box 1 to different production lines.

[0031] Reference Figure 1 Both sides of the top of the housing 1 are welded and fixed with baffles 12, and the handle 11 is located between the baffles 12. The height of the baffles 12 is greater than the height of the PCB board outside the housing 1. The baffles 12 protect the sides of the PCB board, preventing operators from accidentally touching the PCB board, reducing the risk of hand cuts or PCB board deformation, and improving operational safety. A storage box 13 is welded and fixed to the outer wall of the housing 1. The storage box 13 is located below the handle 11, which is convenient for placing recording tools, etc.

[0032] Reference Figure 1 and Figure 2 The rollers 2 are omnidirectional wheels equipped with brakes, ensuring that the housing 1 remains stationary after being moved to a designated position, facilitating the handling of PCB boards by operators. Rubber plates 14 are fixedly connected to the adjacent sides of the two limiting plates 4. The rubber plates 14 and limiting plates 4 are integrally formed, and the slots 5 extend laterally onto the rubber plates, allowing the edges of the PCB board to make flexible contact with the inner wall of the slots 5, which helps reduce scratches or wear on the edges of the PCB board.

[0033] The implementation principle of the PCB board transfer device disclosed in this application is as follows: the operator vertically inserts the electroplated PCB board into the slot 5 in the box 1, and fixes the PCB board through the slot 5. The limiting plate 4 between adjacent slots 5 keeps the multiple PCB boards at an appropriate distance, effectively reducing the mutual collision and stacking problems of PCB boards during the transfer process. After the PCB board is electroplated, the wastewater on the board falls into the wastewater collection tank 6 through the through hole 8, which facilitates the subsequent unified discharge of wastewater and effectively solves the problem of water dripping from the PCB board after electroplating.

[0034] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
