Description

Technical Field

[0001] The utility model relates to the field of coating carriers, and particularly relates to a coating carrier with anti-fooling function in the plate feeding direction. Background Technique

[0002] Since copper has excellent electrical conductivity and good physical properties, it is selected as the conductive material for printed circuit boards (PCBs). However, the surface of fresh copper is prone to oxidation, and when exposed to air, a firm and very thin oxide layer (copper oxide and cuprous oxide) is easily formed on its surface. This oxide layer often causes solder joint failures, affecting reliability and service life. Therefore, anti-oxidation protection measures must be adopted on the copper conductors of PCBs, that is, a weldable coating (plating) layer that both covers and is heat-resistant is applied to the fresh copper surface for protection. This is the origin of the surface coating (plating) layer of PCBs.

[0003] In the use of existing coating carriers, new employees often make mistakes in the plate feeding direction at the coating section loading station. Slightly, it will cause coating errors in the coating section and result in board scrapping. Seriously, it will knock the spray heads in the coating section out of alignment. Currently, the entrance of the coating section equipment is not anti-fooling. When employees feed the board in the wrong direction or feed the B side when producing the A side, it cannot be controlled, resulting in incorrect coating positions of the boards and scrapping. Moreover, feeding the board in the wrong direction will cause the risk of damaging the equipment spray heads.

[0004] Therefore, it is necessary to invent a coating carrier with anti-fooling function in the plate feeding direction to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a coating carrier with anti-fooling function in the plate feeding direction, which can effectively solve the above technical problems.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A coating carrier with anti-fooling function in the plate feeding direction, including a bearing plate. Mounting seats are arranged in a row and bolted to the upper and lower parts of the inner cavity of the bearing plate. A driving block is slidably connected to the center of the inner side of the mounting seat. Electric cylinders are bolted to the upper and lower parts of the inner cavity of the bearing plate, and the telescopic ends of the electric cylinders are bolted to the outer sides of the driving blocks. Driving grooves are opened on both sides of the inner cavity of the mounting seat. A linkage gear is rotatably connected to the middle of the inner cavity of the driving groove through a bearing. A first toothed plate is bolted to the outer side of the driving block and passes through the driving groove. Sliding grooves are opened on both sides of the mounting seat. A slider is slidably connected to the inner side of the sliding groove. A second toothed plate is bolted to the inner side of the slider and passes through the driving groove. A first contact plate is arranged in a row on the left side of the inner cavity of the bearing plate, and a second contact plate is arranged in a row on the right side of the inner cavity of the bearing plate. Link rods are hinged to the outer sides of the first contact plate and the second contact plate, and the other ends of the link rods are hinged to the tops of the sliders.

[0007] Preferably, shells are bolted to both the upper and lower sides of the left side of the first contact plate. Springs are bolted to the inner sides of the shells, and contact blocks are bolted to the other ends of the springs. The springs use their own elastic force to push the contact blocks to move towards the inside of the first contact plate. Since protrusions are designed on both the front and rear sides of the contact blocks, the contact blocks can quickly reset after displacement.

[0008] Preferably, pressure plates are bolted to both the upper and lower sides of the inner cavity of the shell, and the outer sides of the contact blocks are slidably connected to the inner side of the first contact plate. The contact blocks contact one side of the PCB board and move outwards until they squeeze the pressure plates. According to the design of the shape of the PCB board and the cooperation of the anti-fooling structure, only when the PCB board is correctly placed on the carrier plate can pressure be generated on the pressure plates during the detection process, so that the PCB board can perform normal coating operations.

[0009] Preferably, anti-fooling inserts are bolted to both the upper and lower sides of the inner side of the second contact plate. The positions and sizes of the anti-fooling inserts are designed according to the actual shape of the PCB board. They can not only push the PCB board between the first contact plate and the second contact plate to prevent the position of the PCB board from shifting during the coating process, but also assist the detection component in detecting whether the PCB board is correctly placed.

[0010] Preferably, detection lights are arranged and bolted to the top of the inner cavity of the carrier plate. When the pressure plate fails to detect pressure data after the detection component runs, it is determined that the placement surface of the PCB board is incorrect, and a red light is lit to warn the staff. When the pressure plate normally senses pressure data, a green light is lit.

[0011] Preferably, a PCB board is placed inside the first contact plate and the second contact plate. The PCB board is the object for the coating device to spray the coating. The anti-fooling component and the detection component are designed according to the actual shape of this PCB board.

[0012] Preferably, the inner sides of the first toothed plate and the second toothed plate are both meshed with the surface of the linkage gear. After the first toothed plate moves vertically, it drives the linkage gear to rotate, and then the second toothed plate is driven to move in the opposite direction.

[0013] In the above technical solution, the technical effects and advantages provided by the present utility model are as follows:

[0014] 1. By components such as the mounting seat, driving block, electric cylinder, driving groove, linkage gear, and first toothed plate, it is convenient to directly move the carrier to the coating device for operation, convenient for quickly loading and regularizing the PCB board, capable of quickly aligning and positioning the PCB board, and can simultaneously position and detect multiple PCB boards, improving the processing efficiency;

[0015] 2. Through components such as the first contact plate, the second contact plate, the housing, the spring, the contact block, the pressure plate, and the anti-fooling insert, when the PCB board is placed incorrectly, the inner cavity of the PCB board faces the first contact plate. Therefore, after being pushed into the inside of the first contact plate, the contact block cannot be pushed normally, and then the device emits a red light alarm through the detection lamp to remind the staff to place it again, improving the continuous detection efficiency of the device.

Detailed Embodiment

[0023] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the following will further introduce the present utility model in detail in conjunction with the drawings.

[0024] The present utility model provides as Figures 1-4A coating carrier for preventing anti-fooling in the feeding direction, including a carrier plate 1. Mounting seats 2 are arranged and bolted up and down inside the carrier plate 1. A driving block 3 is slidably connected to the center inside the mounting seat 2. Electric cylinders 4 are bolted up and down inside the carrier plate 1, and the telescopic ends of the electric cylinders 4 are bolted to the outside of the driving block 3. Driving grooves 5 are formed on both sides inside the mounting seat 2. A linkage gear 6 is rotatably connected to the middle of the driving groove 5 through a bearing. A first toothed plate 7 is bolted to the outside of the driving block 3 and passes through the driving groove 5. Sliding grooves 8 are formed on both sides of the mounting seat 2. A slider 9 is slidably connected to the inside of the sliding groove 8. A second toothed plate 10 is bolted to the inside of the slider 9 and passes through the driving groove 5. A first contact plate 11 is arranged in a row on the left side inside the carrier plate 1. A second contact plate 12 is arranged in a row on the right side inside the carrier plate 1. Link rods 13 are hinged to the outside of the first contact plate 11 and the second contact plate 12, and the other ends of the link rods 13 are hinged to the top of the slider 9.

[0025] On the upper and lower sides of the left side of the first contact plate 11, a housing 14 is bolted. Springs 15 are bolted to the inside of the housing 14, and the other ends of the springs 15 are bolted to a contact block 16. The spring 15 pushes the contact block 16 to move inward towards the first contact plate 11 through its own elastic force. And since protrusions are designed on the front and rear sides of the contact block 16, the contact block 16 can quickly reset after displacement.

[0026] Pressure plates 17 are bolted to the upper and lower sides inside the housing 14. The outside of the contact block 16 is slidably connected to the inside of the first contact plate 11. The contact block 16 contacts one side of the PCB board 20 and moves outward until it squeezes the pressure plate 17. According to the design of the shape of the PCB board 20 and the cooperation of the anti-fooling structure, only when the PCB board 20 is correctly placed on the carrier plate 1 can pressure be generated on the pressure plate 17 during the detection process, so that the PCB board 20 can perform normal coating operations.

[0027] Anti-fooling inserts 18 are bolted to the upper and lower sides inside the second contact plate 12. The position and size of the anti-fooling inserts are designed according to the actual shape of the PCB board 20. It can not only push the PCB board 20 between the first contact plate 11 and the second contact plate 12 to prevent the position of the PCB board 20 from shifting during the coating process, but also assist the detection component to detect whether the PCB board 20 is placed correctly.

[0028] Detection lights 19 are bolted in a row on the top inside the carrier plate 1. When the detection component runs and no pressure data can be detected on the pressure plate 17, it is determined that the placement surface of the PCB board 20 is incorrect, and a red light is lit to give a warning to the staff. When the pressure plate 17 normally senses pressure data, a green light is lit.

[0029] The inner sides of the first contact plate 11 and the second contact plate 12 are provided with a PCB board 20. The PCB board 20 is the object to be coated by the coating device. The anti-fooling component and the detection component are designed according to the actual shape of the PCB board 20.

[0030] The inner sides of the first toothed plate 7 and the second toothed plate 10 are both meshed with the surface of the linkage gear 6. After the first toothed plate 7 moves vertically, it drives the linkage gear 6 to rotate, and then the second toothed plate 10 is driven to move in the opposite direction.

[0031] Refer to the attached instructions Figures 1-4 , working principle: Through components such as the mounting seat 2, the driving block 3, the electric cylinder 4, the driving groove 5, the linkage gear 6, and the first toothed plate 7, during the use of the device, first place the PCB board 20 between the first contact plate 11 and the second contact plate 12, and then start the electric cylinder 4 to make the electric cylinder 4 push the driving block 3 to move horizontally in the driving groove 5. When the driving block 3 moves outward, it will drive the first toothed plate 7 to move outward. The movement of the first toothed plate 7 will drive the linkage gear 6 to rotate. The rotation of the linkage gear 6 will drive the second toothed plate 10 to move horizontally, and then drive the slider 9 to move in the sliding groove 8, so that the slider 9 drives the first contact plate 11 and the second contact plate 12 to move horizontally towards each other through the connecting rod 13, fixing the PCB board 20, enabling the PCB board 20 to be correctly placed at a position on the carrier plate 1, facilitating directly moving the carrier to the coating device for operation, facilitating rapid board loading and regularization of the PCB board 20, being able to quickly align and position the PCB board 20, and being able to simultaneously position and detect multiple PCB boards 20, improving the processing efficiency. Through components such as the first contact plate 11, the second contact plate 12, the housing 14, the spring 15, the contact block 16, the pressure plate 17, and the anti-fooling insert 18, during the use of the device, the connecting rod 13 pushes the first contact plate 11 and the second contact plate 12 to move to both sides. Here, it should be noted that due to the limited internal space of the carrier plate 1, the first contact plate 11 and the second contact plate 12 on both sides of the inner cavity of the carrier plate 1 are fixed, while other first contact plates 11 and second contact plates 12 are all driven by the connecting rod 13. When the PCB board 20 is pushed by the contact plate and is pushed into the inner side of the first contact plate 11, if the placement direction is correct, the left side of the PCB board 20 will squeeze the contact block 16 and make the contact block 16 move outward until it contacts the pressure plate 17. This is the correct operation process. When the PCB board 20 is placed incorrectly, the inner cavity of the PCB board 20 faces the first contact plate 11. Therefore, after being pushed into the inner side of the first contact plate 11, it cannot normally push the contact block 16, and then the device emits a red light alarm through the detection lamp 19 to remind the staff to place it again, improving the continuous detection efficiency of the device.

[0032] Only some exemplary embodiments of the present utility model have been described by way of illustration. Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present utility model. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present utility model.
