Technical Field

[0001] The utility model relates to the technical field of PCB coating, in particular to a product positioning structure of a coating device. Background Technique

[0002] PCB (printed circuit board) coating is a crucial link in the electronic manufacturing process. By coating a protective material on the surface of the PCB, it can effectively prevent the corrosion and damage of the circuit by the external environment, improve the service life and reliability of electronic products. The coating materials usually include silicone, polyurethane, acrylic, etc. These materials have good insulation, moisture-proof and anti-corrosion properties. Therefore, the coating process is particularly important for PCBs with dense electronic components.

[0003] At present, there are various PCB coating devices on the market, but their positioning structures generally have some defects. The positioning structure usually requires dozens of rotating buckles to be set in the coating area of each PCB. The traditional buckle design is at the edge position of the PCB to prevent the product from falling during the coating process. Although this design can effectively fix the PCB, the operation is complex, which greatly affects the operation efficiency, and it is also easy to collide with the valve head during the coating process, affecting the coating operation.

[0004] Therefore, a product positioning structure of a coating device is needed to solve the above technical defects. Content of the Utility Model

[0006] To achieve the above purpose, the utility model provides the following technical scheme: A product positioning structure of a coating device, including a base and a PCB board. The PCB board is placed above the base. A set of vertical rods is arranged at the outer four corners of the base. Rod sleeves are respectively sleeved outside the vertical rods. A clamping groove is welded on one side of the rod sleeve. A cover plate is clamped in the clamping groove. The cover plate covers above the PCB board. Four groups of positioning holes are arranged at the edge of the cover plate. Positioning blocks are arranged at the inner four corners of the base. The positioning blocks are respectively located at the positioning holes. Flap pieces are fixed at the top ends of the positioning blocks.

[0010] Preferably, a handle is fixedly connected between the same-side rod sleeves, and two groups of handles are provided.

[0011] Preferably, an installation piece is welded at the front-end opening inside the base. Fixed blocks and spring blocks are arranged on the inner wall of the installation piece. Side blocks are respectively welded on both sides inside the base. A return spring is fixedly connected to the side block. One side of the return spring is fixedly connected to a rack. Four groups of racks are provided. The lower half of the positioning block is located inside the base and is fixedly sleeved with a semi-gear.

[0012] Preferably, four groups of semi-gears are provided, and the racks and the semi-gears are respectively meshed and connected.

[0013] Preferably, a connecting rod is fixedly connected to the rack. A pulling rope is fixedly connected to one side of the connecting rod. The bottom end of the pulling rope is connected to a moving block. The moving block is located between two groups of installation pieces. Two groups of grooves are arranged on both sides of the outer wall of the moving block. The grooves are in interference fit with the fixed blocks and the spring blocks. An operating block is welded at the front end of the moving block.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows: The product positioning structure of this coating device not only realizes that it is not necessary to equip each group of mold grooves with a set of buckles, greatly improves the operation efficiency, realizes the function of facilitating rapid loading and unloading, but also realizes the reduction of operation steps;

[0015] (1) By providing a PCB board, a cover plate, mold grooves, a baffle, positioning holes, and positioning blocks, before the coating operation starts, first place the PCB board on the base so that it is located between four groups of positioning blocks, and then push the cover plate downward so that six groups of mold grooves cover the PCB board. Pull the operating block, and through the linkage operation, the four groups of positioning blocks rotate simultaneously, and the baffle rotates 90° from parallel to the positioning hole to block the positioning hole, so that the PCB board is fixed under the cover plate and cannot move. When the machine performs coating, the PCB board will not shift. After the coating is completed, rotate the positioning block with one key to release the fixation. Only four groups of positioning blocks are needed to fix the PCB board, and it is not necessary to equip each group of mold grooves with a set of buckles, greatly improving the operation efficiency;

During operation, the operating block is pulled outward, so that the spring block is squeezed out of the groove by friction and clamped with the fixed block. The distance that the moving block moves outward is converted into horizontal movement of the connecting rod by the pulling of the pull rope, thereby driving the positioning block to engage and rotate 90° through the rack. The baffles at the four groups of positioning blocks are rotated and buckled above the positioning holes, realizing one-key clamping. After coating is completed, the operating block is pushed back. Under the reset spring, the half gear drives the positioning block to rotate, and the baffle is opened, so that the cover plate can be lifted upward. The four groups of positioning blocks can be clamped and loosened with one key through linkage, without the need to move the positioning blocks one by one, thereby reducing the number of operating steps.

Positioning blocks 6 are provided at the four corners inside the base 5. The positioning blocks 6 are respectively located at the positioning holes 12. Flap 11 is fixed at the top of each positioning block 6. A groove 14 matching the area to be coated of the PCB board 7 is provided inside the cover plate 13;

[0025] Specifically, as Figure 1 and Figure 2 shown, before the coating operation starts, first place the PCB board 7 on the base 5 so that it is located between the four sets of positioning blocks 6. Then push the cover plate 13 downward so that the six sets of grooves 14 cover above the PCB board 7. Pull the operation block 8, and through the linkage operation, the four sets of positioning blocks 6 rotate simultaneously. The flap 11 rotates 90° from being parallel to the positioning hole 12 and catches the positioning hole 12, so that the PCB board 7 is fixed under the cover plate 13 and cannot move. When the machine performs coating, the PCB board 7 will not shift. After the coating is completed, rotate the positioning block 6 with one key to release the fixation. Only four sets of positioning blocks 6 are needed to fix the PCB board 7, and it is not necessary to equip a set of buckles for each set of grooves 14.

[0026] Embodiment 2: The flap 11 is a rhombus piece, the positioning hole 12 is a semi-circular groove, the clamping groove 4 is "L"-shaped. A magnetic attraction ring 10 is bonded around the top of the sleeve 3. Magnetic attraction blocks 1 are provided at the top of each vertical rod 2. The magnetic attraction block 1 and the magnetic attraction ring 10 can be magnetically attracted and fitted. A handle 9 is fixedly connected between the sleeves 3 on the same side. Two sets of handles 9 are provided;

[0027] Specifically, as Figure 1 and Figure 2 shown, after the coating operation is completed, push the operation block 8 into the base 5, and the four sets of positioning blocks 6 rotate to release the clamping with the positioning hole 12. Then hold the two handles 9 and lift the sleeve 3 from the vertical rod 2. The flap 11 at the top of the sleeve 3 is magnetically fixed to the magnetic attraction block 1, and then the PCB board 7 can be taken away and a new set of PCB boards 7 can be placed.

[0028] Embodiment 3: An installation piece 15 is welded at the front-end opening inside the base 5. A fixing block 16 and a spring block 17 are arranged on the inner wall of the installation piece 15. Side blocks 23 are respectively welded on both sides inside the base 5. A return spring 22 is fixedly connected to the side block 23. A rack 20 is fixedly connected to one side of the return spring 22. Four groups of racks 20 are provided. The lower half of the positioning block 6 is located inside the base 5 and is fixedly sleeved with a half gear 21. A total of four groups of half gears 21 are provided. The racks 20 and the half gears 21 are respectively meshed and connected. A connecting rod 19 is fixedly connected to the rack 20. A pulling rope 18 is fixedly connected to one side of the connecting rod 19. The bottom end of the pulling rope 18 is connected to a moving block 24. The moving block 24 is located between the two installation pieces 15. Two groups of grooves 25 are arranged on both sides of the outer wall of the moving block 24. The grooves 25 are in interference fit with the fixing block 16 and the spring block 17. An operation block 8 is welded at the front end of the moving block 24;

[0029] Specifically, as Figure 1 , Figure 3 and Figure 4 shown, a linkage mechanism for synchronously rotating the four positioning blocks 6 is arranged inside the base 5. During operation, the operation block 8 is pulled outwards, so that the spring block 17 is extruded by the frictional force and disengages from the groove 25 and is clamped with the fixing block 16. The distance that the moving block 24 moves outwards is converted into the horizontal movement of the connecting rod 19 through the pulling of the pulling rope 18, so as to drive the positioning block 6 to meshingly rotate by 90° through the rack 20. The retaining pieces 11 at the four positioning blocks 6 rotate and buckle above the positioning holes 12, realizing one-key clamping. After coating, the operation block 8 is pushed back. Under the reset spring action of the return spring 22, the half gear 21 drives the positioning block 6 to rotate back, and the retaining piece 11 opens, so that the cover plate 13 can be lifted upwards. Through the linkage, one-key clamping and loosening of the four positioning blocks 6 are realized, and there is no need to dial the positioning blocks 6 one by one.

[0030] Working principle: Before the coating operation starts, place the PCB board 7 on the base 5 so that it is located between the four groups of positioning blocks 6. Then, push the cover plate 13 downward so that the six groups of groove patterns 14 cover above the PCB board 7. Pull the operation block 8, so that the spring block 17 is extruded by the frictional force and disengages from the groove 25, and is clamped with the fixed block 16. The distance that the moving block 24 moves outward is converted into the horizontal movement of the connecting rod 19 through the pulling of the pull rope 18. Thus, the positioning block 6 is driven by the rack 20 to mesh and rotate by 90°. The retaining pieces 11 at the four groups of positioning blocks 6 rotate and buckle above the positioning holes 12, realizing one-key clamping, so that the PCB board 7 is fixed under the cover plate 13 and cannot move. When the machine performs coating, the PCB board 7 will not shift. After the coating operation is completed, push the operation block 8 into the base 5. Under the reset spring of the return spring 22, the semi-gear 21 drives the positioning block 6 to rotate back, the retaining piece 11 opens, and the four groups of positioning blocks 6 rotate to release the clamping with the positioning holes 12. Then, hold the two handlebars 9 and lift the rod sleeve 3 from the vertical rod 2, and the cover plate 13 can be lifted upward. The retaining piece 11 at the top of the rod sleeve 3 is magnetically fixed with the magnetic attraction block 1, and the PCB board 7 can be taken away and a new group of PCB boards 7 can be placed.
