[0023] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0024] refer to Figure 1 As shown in the figure, this utility model embodiment provides an SMT template single-machine automatic loading and unloading device, including a frame 1, a fixed plate 2, a movable plate 3, and a spacing adjustment mechanism 4.

[0025] The frame 1 serves to support other components. The fixed plate 2 is set on one side of the frame 1, and the movable plate 3 is set inside the frame 1. The movable plate 3 is parallel to the fixed plate 2. The top and bottom of the frame 1 are equipped with slide rails 11, and the upper and lower ends of the movable plate 3 are slidably engaged with the slide rails 11.

[0026] The lower end of the frame 1 is provided with a spacing adjustment mechanism 4, which is connected to the lower end of the movable plate 3.

[0027] refer to Figure 2 As shown, the spacing adjustment mechanism 4 includes a lead screw 41, a nut 42, and a handle 43. The two ends of the lead screw 41 are rotatably supported in the frame 1 by bearing seats and are located below the lower end of the movable plate 3. The nut 42 is mounted on the lead screw 41 and threadedly engaged with it. The nut 42 is fixedly connected to the lower end of the movable plate 3. The handle 43 is located at one end of the lead screw 41. By rotating the handle 43, the lead screw 41 can be driven to rotate, thereby causing the nut 42 to move along the axis of the lead screw 41. The nut 42 drives the movable plate 3 to move together, thereby changing the spacing between the movable plate 3 and the fixed plate 2.

[0028] The fixed plate 2 has a first partition 21 on the side facing the movable plate 3. There are multiple first partitions 21, which are distributed at intervals along the height direction of the fixed plate 2. A first slot is formed between two adjacent first partitions 21.

[0029] refer to Figure 3 As shown, a first arc-shaped protrusion 22 is provided on the upper side of the first spacer 21. There are multiple first arc-shaped protrusions 22, which are distributed at intervals along the length direction of the first spacer 21.

[0030] The inner side of the movable plate 3 is provided with a second partition 31. There are multiple second partitions 31, which are distributed at intervals along the height direction of the movable plate 3. A second slot is formed between two adjacent second partitions 31. The height spacing of the second slot is the same as the height spacing of the first slot.

[0031] refer to Figure 4 As shown, a second arc-shaped protrusion 32 is provided on the upper side of the second spacer 31. There are multiple second arc-shaped protrusions 32, which are distributed at intervals along the length direction of the second spacer 31.

[0032] When the PCB board is placed between the fixed plate 2 and the movable plate 3, both ends of the PCB board are respectively locked in the first slot and the second slot, and the lower side of the PCB board is supported on the first arc-shaped boss 22 and the second arc-shaped boss 32. The arrangement of the first arc-shaped boss 22 and the second arc-shaped boss 32 greatly reduces the contact area between the PCB board and the first spacer 21 and the second spacer 31, thereby reducing friction. This makes it easier to push the PCB board into the first slot and the second slot, and also makes it easier to push the PCB board out of the first slot and the second slot.

[0033] The corresponding fixing plate 2 in the first slot is provided with a third arc-shaped protrusion 23. There are multiple third arc-shaped protrusions 23, which are distributed at intervals along the length direction of the first slot.

[0034] The corresponding movable plate 3 in the second slot is provided with a fourth arc-shaped protrusion 33. There are multiple fourth arc-shaped protrusions 33, which are distributed at intervals along the length of the second slot.

[0035] The third arc-shaped boss 23 and the fourth arc-shaped boss 33 can reduce the contact area between the two ends of the PCB board and the fixed plate 2 and the movable plate 3, thereby reducing friction. This makes it easier to push the PCB board into the first slot and the second slot, and also makes it easier to push the PCB board out of the first slot and the second slot.

[0036] The fixed plate 2 has baffles 24 on both sides in the width direction. The baffles 24 are vertically arranged, and their two ends are rotatably connected to the upper and lower ends of the fixed plate 2, respectively. A first limiting block 25 is provided on the inner side of the upper or lower end of the fixed plate 2 near the edge, and a second limiting block 26 is provided on the outer side near the edge. Alternatively, the first limiting block 25 can be provided on the inner side of both the upper and lower ends of the fixed plate 2 near the edge, and the second limiting block 26 can be provided on the outer side near the edge. A first magnetic element is provided on the first limiting block 25. The second limiting block 26 is equipped with a second magnetic component, and the upper or lower end of the baffle 24 is equipped with a metal component or a magnetic component. Alternatively, both the upper and lower ends of the baffle 24 can be equipped with metal components or magnetic components. When a PCB board is loaded inside the frame 1 for transport, rotating the baffle 24 inwards causes the first magnetic component on the first limiting block 25 to attract the metal component or magnetic component on the baffle 24, firmly holding the baffle 24 in place. The baffle 24 blocks both ends of the first slot, preventing the PCB board from slipping out during transport. Rotating the baffle 24 outwards causes the metal component or magnetic component on the baffle 24 to attract the second magnetic component, firmly holding the baffle 24 in place. At this point, the PCB board can be pushed out of the first and second slots. In this embodiment, the magnetic component can be a magnet.

[0037] The upper end of the frame 1 is provided with a lifting ring 12. The number of lifting rings 12 can be multiple, which facilitates the lifting and transportation of the frame 1.

[0038] Support legs 13 are provided at the four corners of the bottom of frame 1. The support legs 13 are designed to facilitate forklift lifting and transportation.

[0039] The above description is merely a preferred embodiment of this utility model and does not constitute any limitation on this utility model. Any person skilled in the art can make many possible variations and modifications to the technical solution of this utility model, or modify it into equivalent embodiments, without departing from the scope of the technical solution of this utility model. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technology of this utility model without departing from the scope of the technical solution of this utility model shall fall within the protection scope of this technical solution.
