Description

Technical Field

[0002] Circuit board manufacturing refers to the process of processing copper-clad laminates into electronic substrates with specific circuit functions through processes such as cutting, drilling, etching, and soldering. Its core objective is to ensure that the circuit board surface is undamaged and that the circuits have good conductivity in a high-precision, high-efficiency production process to meet the high reliability requirements of electronic devices. In the circuit board manufacturing process, transfer devices are responsible for the safe and efficient transfer of semi-finished or finished circuit boards between different processes. Their performance directly affects production efficiency and product quality.

[0003] Traditional circuit board transfer devices have the following limitations: circuit boards are directly stacked, the bottom board is deformed due to gravity, the surface is easily scratched by sharp corners, multi-layer circuit boards are adhered by electrostatic adsorption, and separation can easily cause edge damage or component detachment. The lack of layered or compartmentalized structure results in low space utilization and cannot avoid stacking risks. To address these issues, we provide a transfer device for circuit board processing to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a transfer device for circuit board processing. Through the cooperation of the transfer mechanism and the limiting mechanism, it solves the problems of the existing transfer devices, such as the direct stacking of circuit boards, deformation of the bottom plate due to gravity, easy scratches on the surface by sharp corners, and easy edge damage or component falling off when separating multi-layer circuit boards due to electrostatic adsorption and adhesion.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0006] This utility model relates to a transfer device for circuit board processing, comprising an RGV vehicle, a transfer mechanism on the top of the RGV vehicle, a limiting mechanism on one side of the transfer mechanism, the transfer mechanism comprising a transfer frame fixedly connected to the top of the RGV vehicle, a transfer plate disposed on one side of the transfer frame, an electric pulley disposed inside the transfer plate, and an extension plate fixedly connected to one side of the transfer plate, the limiting mechanism comprising a vertical plate disposed on the top of the RGV vehicle, a positioning plate disposed on one side of the vertical plate, and a limiting plate fixedly connected to the bottom of the transfer plate.

[0007] The present invention is further configured such that a first hydraulic cylinder is fixedly connected inside the transfer frame, and an electromagnet is fixedly connected to the output end of the first hydraulic cylinder.

[0008] The present invention is further configured such that twelve extension plates are arranged in a group on one side inside the transfer frame, and there are a total of eight groups of extension plates.

[0009] The present invention is further configured such that a vertical rod is fixedly connected to one side of the extension plate, and a movable through groove adapted to the extension plate is provided on the side of the transfer frame near the transfer plate.

[0010] The present invention is further configured such that a sliding rod is slidably connected inside the extension plate, and a spring is slidably connected to the surface of the sliding rod, and the spring is disposed between the upper and lower extension plates.

[0013] The present invention has the following beneficial effects.

[0014] 1. This utility model effectively avoids the problem of circuit board deformation caused by direct stacking during transportation by forming independent partition layers through multi-layer transfer plates and extension plates in the transfer mechanism. The extension plates use magnetic blocks and electromagnets to press and fix the circuit boards, which can accommodate circuit boards of different thicknesses and ensure that each layer of circuit boards remains stable during transportation. In addition, the transfer plates and limiting plates are made of anti-static materials, reducing the risk of adhesion caused by electrostatic adsorption, thereby protecting the surface and edges of the circuit boards from damage and improving transportation safety and product quality.

[0015] 2. This utility model achieves precise positioning of the circuit board by driving the positioning plate to move through the second hydraulic cylinder in the limiting mechanism, ensuring that it does not deviate during dynamic transportation. The limiting plate cooperates with the bottom of the transfer plate to further prevent the circuit board from sliding or tilting. At the same time, the design of the slide bar and spring allows the extension plate to automatically reset after the electromagnet is de-energized, simplifying the operation process. The electric pulley allows the circuit board to move smoothly, reducing the risk of friction and scratches. The overall design takes into account both efficiency and safety, solving the problems of circuit board damage and inaccurate positioning in traditional transfer devices.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0024] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Example 1

[0026] Please see Figures 1-5 This utility model is a transfer device for circuit board processing, including an RGV cart 1, a transfer mechanism 2 on the top of the RGV cart 1, and a limiting mechanism 3 on one side of the transfer mechanism 2. The transfer mechanism 2 includes a transfer frame 201 fixedly connected to the top of the RGV cart 1, a transfer plate 202 on one side of the transfer frame 201, an electric pulley 203 inside the transfer plate 202, and an extension plate 204 fixedly connected to one side of the transfer plate 202. The limiting mechanism 3 includes a vertical plate 301 on the top of the RGV cart 1, a positioning plate 302 on one side of the vertical plate 301, and a limiting plate 303 fixedly connected to the bottom of the transfer plate 202. The transfer plate 202, the electric pulley 203, the positioning plate 302, and the limiting plate 303 are all made of thermoplastic elastomer antistatic material.

[0027] Specifically: Through the setting of the transfer mechanism 2, the multi-layer transfer plate 202 and the extension plate 204 form an independent separation layer, avoiding the direct stacking of circuit boards and deformation due to pressure. The extension plate 204 is fixed by the magnetic block 7 and the electromagnet 5, and the spacing can be adjusted to accommodate circuit boards of different thicknesses. Through the setting of the limiting mechanism 3, the second hydraulic cylinder 11 drives the positioning plate 302 to move and limit the circuit board to ensure that the position does not shift during transportation. The limiting plate 303 cooperates with the bottom of the transfer plate 202 to prevent the circuit board from sliding or tilting during dynamic transportation. The transfer mechanism 2 realizes efficient and flexible layered transportation, and the limiting mechanism 3 provides precise positioning and protection, jointly solving the problems of stacking deformation, scratches and adhesion in traditional transfer, and improving the yield and efficiency of circuit board processing.

[0028] Example 2

[0029] Please see Figures 1-5 Based on embodiment 1, a first hydraulic cylinder 4 is fixedly connected inside the transfer frame 201, and an electromagnet 5 is fixedly connected to the output end of the first hydraulic cylinder 4. Twelve extension plates 204 are arranged in a group on one side inside the transfer frame 201, with a total of eight groups of extension plates 204. A connecting plate 6 is fixedly connected between the top two extension plates 204, and a magnetic block 7 is fixedly connected to the bottom of the connecting plate 6. A vertical rod 8 is fixedly connected to one side of the extension plate 204. A movable through groove adapted to the extension plate 204 is opened on the side of the transfer frame 201 near the transfer plate 202. A sliding rod 9 is slidably connected inside the extension plate 204, and a spring 10 is slidably connected to the surface of the sliding rod 9. The spring 10 is arranged between the upper and lower extension plates 204. A sliding groove adapted to the electric pulley 203 is opened inside the transfer plate 202. The electric pulley 203 is movably connected inside the sliding groove through a bearing. A second hydraulic cylinder 11 is fixedly connected to one side of the vertical plate 301, and the output end of the second hydraulic cylinder 11 is fixedly connected to the positioning plate 302.

[0030] Specifically: The first hydraulic cylinder 4 is used to push the electromagnet 5 to move up and down. The connecting plate 6 and the magnetic block 7 are connected. The magnetic block 7 is made of ferromagnetic material. When the electromagnet 5 is energized, it generates magnetic force to attract the magnetic block 7. After the magnetic block 7 is magnetically attracted and fixed by the electromagnet 5, the connecting plate 6 can drive the extension plate 204 to move downward. The vertical rod 8 is used to fix the vertically arranged extension plate 204 together. The sliding rod 9 and the spring 10 are used. After the electromagnet 5 is de-energized, the magnetic block 7 loses its magnetic attraction. Under the reset action of the spring 10, the extension plate 204 is reset upward. The sliding rod 9 makes the extension plate 204 move up and down vertically. The sliding groove is used to place the electric pulley 203 inside the transfer plate 202. The drive motor of the electric pulley 203 is also set inside the sliding groove. The pulleys are synchronously driven by a synchronous belt. The second hydraulic cylinder 11 is used to push the positioning plate 302 to move and adjust the position of the positioning plate 302.

[0031] The working principle of this utility model is as follows: the position of the positioning plate 302 is adjusted according to the size of the circuit board, the second hydraulic cylinder 11 drives the positioning plate 302 to move to the designated position, the circuit board material to be transferred is placed on the surface of the electric pulley 203 in sequence, the electric pulley 203 drives the circuit board to move towards the positioning plate 302, and the drive motor of the electric pulley 203 is stopped when the circuit board contacts the positioning plate 302.

[0032] Then, the first hydraulic cylinder 4 drives the electromagnet 5 to move towards the magnetic block 7. After the electromagnet 5 contacts the magnetic block 7, it is energized. At this time, the electromagnet 5 attracts the magnetic block 7. Then, the first hydraulic cylinder 4 retracts, driving the connecting plate 6 to move downward. The connecting plate 6 drives the extension plate 204 to move downward. The extension plate 204 drives the transfer plate 202 to move downward. The transfer plate 202 moves downward as a whole. When the limiting plate 303 at the bottom of the transfer plate 202 contacts the surface of the circuit board, the circuit board is limited. At this time, the RGV car 1 moves the circuit board to the transfer position according to the track. Then, the electromagnet 5 is de-energized. At this time, the magnetic block 7 is separated from the electromagnet 5. Under the reset action of the spring 10, the transfer plate 202 is reset upward, and the limitation on the circuit board is released. At this time, the electric pulley 203 can reverse to move the circuit board out of the transfer frame 201.

[0033] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
