[0002] PCBs, also known as printed circuit boards, are the carriers for electrical connections of electronic components and are one of the important components in the electronics industry. Currently, PCBs are generally dried using hot air drying ovens. Inside the oven, PCBs are lifted and moved using clamping devices. However, assembling and removing PCBs from these devices still primarily relies on manual operation by workers, resulting in high labor intensity, low efficiency, and significant safety hazards.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A clamp opening device for drying PCB board includes a base plate and a lifting drive mechanism for driving the base plate to reciprocate in a vertical direction. Several sets of pressing blocks are movably arranged on the base plate. The pressing blocks are fixedly connected to a movable plate through connecting rods. An opening and closing drive mechanism is installed on the movable plate for driving the movable plate to reciprocate in a horizontal direction, so that the movable plate drives the pressing blocks to reciprocate.

[0006] As a further improvement to the above technical solution:

[0007] Several sets of positioning plates are fixedly disposed on the substrate, and positioning slots are formed on the positioning plates.

[0008] The pressing block is slidably connected to the substrate via a sliding connection mechanism, which includes a slide rail fixedly disposed on the substrate and a slider fixedly disposed on the pressing block.

[0011] Compared with the prior art, the advantages of this utility model are:

[0012] This utility model discloses a clamp opening device for PCB board drying, comprising a base plate and a lifting drive mechanism. A pressing block is movably disposed on the base plate and is fixedly connected to a movable plate via a connecting rod. An opening and closing drive mechanism is provided between the movable plate and the base plate. The lifting drive mechanism drives the base plate to descend so that the pressing block descends to face the clamp on the crossbeam. The opening and closing drive mechanism drives the movable plate to move away from the base plate, thereby moving the pressing block closer to the clamp. The pressing block abuts against the clamp and opens the clamp, making it easy to place the PCB board at the clamp opening or remove the PCB board from the clamp. It occupies little space, can adapt to automated operations in narrow areas, reduces manual operation links, reduces the labor intensity of workers, and can effectively improve production efficiency and safety.

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] like Figures 1 to 6 As shown, the PCB board drying clamp opening device of this embodiment includes a base plate 1 and a lifting drive mechanism 2 for driving the base plate 1 to reciprocate in the vertical direction. Several sets of pressing blocks 3 are movably arranged on the base plate 1. The pressing blocks 3 are fixedly connected to the movable plate 5 through the connecting rod 4. The movable plate 5 is equipped with an opening and closing drive mechanism 6 for driving the movable plate 5 to reciprocate in the horizontal direction, so that the movable plate 5 drives the pressing blocks 3 to reciprocate. The PCB board drying clamp opening device includes a base plate 1 and a lifting drive mechanism 2. A pressing block 3 is movably disposed on the base plate 1. The pressing block 3 is fixedly connected to a movable plate 5 via a connecting rod 4. An opening and closing drive mechanism 6 is disposed between the movable plate 5 and the base plate 1. The lifting drive mechanism 2 drives the base plate 1 to descend so that the pressing block 3 descends to face the clamp 100 on the crossbeam 200. The opening and closing drive mechanism 6 drives the movable plate 5 to move away from the base plate 1, thereby driving the pressing block 3 to move closer to the clamp 100. The pressing block 3 abuts against the clamp 100 and opens the clamp 100, making it easy to place the PCB board at the opening of the clamp 100 or remove the PCB board from the clamp 100. It occupies little space, can adapt to automated operations in narrow areas, reduces manual operation links, reduces the labor intensity of workers, and can effectively improve production efficiency and safety.

[0023] Preferably, a plurality of positioning plates 7 are fixedly disposed on the substrate 1, and the positioning plates 7 are provided with positioning slots 701. In this embodiment, as shown... Figure 6 As shown, during the lifting and lowering process of the base plate 1, the positioning slot 701 on the positioning plate 7 mainly serves to center and calibrate the crossbeam 200 to ensure that the clamp 100 on the crossbeam 200 is aligned with the position of the pressing block 3, thus ensuring the stability of the pressing block 3 moving and opening the clamp 100.

[0024] Preferably, the pressing block 3 is slidably connected to the base plate 1 via a sliding connection mechanism 8. The sliding connection mechanism 8 includes a slide rail 801 fixedly disposed on the base plate 1 and a slider 802 fixedly disposed on the pressing block 3. In this embodiment, the sliding connection mechanism 8 adopts the form of slider 802 slidingly connected to slide rail 801, which has the advantages of simple structure, convenient and quick assembly and disassembly, long service life, and low cost. The slide rail 801 is installed on the base plate 1, and the slider 802 is installed on the pressing block 3. The pressing block 3 is slidably connected to the base plate 1. The rigid structure and precision machining of the slide rail 801 can ensure that the pressing block 3 moves along a fixed trajectory on the base plate 1, avoiding the pressing block 3 from deviating during reciprocating movement.

[0025] Preferably, a guide mechanism 9 is provided between the base plate 1 and the movable plate 5. The guide mechanism 9 includes a guide post 901 fixedly disposed on the base plate 1 and a guide sleeve 902 fixedly disposed on the movable plate 5. The guide post 901 passes through the guide sleeve 902. In this embodiment, the outer wall of the guide post 901 is tightly fitted with the inner wall of the guide sleeve 902 to ensure that the movable plate 5 moves relative to the base plate 1 along the axial direction of the guide post 901, effectively resisting radial loads and preventing the movable plate 5 from swaying during reciprocating movement.

[0026] Preferably, the lifting drive mechanism 2 includes a first telescopic cylinder 201, the cylinder body of which is fixedly installed inside the PCB board drying oven, and the piston rod of which is fixedly connected to the base plate 1; the opening and closing drive mechanism 6 includes a second telescopic cylinder 601, the cylinder body of which is fixedly installed on the movable plate 5, and the piston rod of which is fixedly connected to the base plate 1. In this embodiment, both the lifting drive mechanism 2 and the opening and closing drive mechanism 6 adopt the form of telescopic cylinders, which has the advantages of simple and compact structure, small space occupation, and convenient and quick assembly and disassembly. In other embodiments, the lifting drive mechanism 2 and the opening and closing drive mechanism 6 can also adopt components with reciprocating movement functions such as gear and rack transmission mechanism, screw transmission mechanism, electric cylinder, and hydraulic cylinder, and are not limited to this embodiment.

[0027] In practical applications, such as Figure 6As shown, in the initial state, the base plate 1 is located above the crossbeam 200. When a set of crossbeams 200 are in place, the first telescopic cylinder 201 drives the base plate 1 to descend. The positioning slot 701 on the positioning plate 7 serves to center and calibrate the crossbeam 200 to ensure that the clamp 100 on the crossbeam 200 is aligned with the position of the pressing block 3. Then, the second telescopic cylinder 601 extends, and the cylinder body and the movable plate 5 of the second telescopic cylinder 601 move away from the base plate 1. The movable plate 5 drives the pressing block 3 to move through the connecting rod 4, thereby causing the pressing block 3 to abut against the clamp 100 and open the clamp 100. The robotic arm places the PCB board at the opening of the clamp 100. Then, the second telescopic cylinder 601 retracts, and the cylinder body and movable plate 5 of the second telescopic cylinder 601 move closer to the substrate 1. The movable plate 5 drives the pressing block 3 to move through the connecting rod 4, thereby releasing the pressing block 3 from the clamp 100, and allowing the clamp 100 to hold the PCB board. The first telescopic cylinder 201 drives the substrate 1 to rise, and the substrate 1 is positioned above the crossbeam 200, waiting for the next set of crossbeams 200 to arrive. The above is a single complete working process of the clamp opening device for drying PCB boards of this utility model.

[0028] The above description is merely a preferred embodiment of this utility model, and the protection scope of this utility model is not limited to the above embodiments. For those skilled in the art, improvements and modifications obtained without departing from the technical concept of this utility model should also be considered within the protection scope of this utility model.
