[0003] In the Chinese utility model patent "A PCB board welding carrier convenient for placing and taking PCB boards" with the existing publication number CN215499804U, "When the PCB board needs to be placed in the carrier, turn on the motor 21 to drive the rotating rod 27 to rotate, and the sliding block 24 slides to rotate the rotating plate, and the connecting block and the lifting plate 23 move upward. When the top of the lifting plate 23 is flush with the top of the carrier body 1, turn off the motor 21, place the PCB board on the lifting plate 23, turn on the motor 21 again, reset the lifting plate 23, and turn off the motor 21 again to complete the lifting." When taking and placing the PCB board, the motor needs to be started multiple times, which is more troublesome. Utility Model Content

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] See also Figure 1-3 The utility model provides a technical solution: a welding carrier that is convenient for taking and placing PCB boards, comprising:

[0031] like Figure 1 The base 1 shown;

[0032] like Figure 1 The two groups of concave plates 4 shown are slidably disposed between the inner walls of the base 1 on both sides, and are used to place the PCB board, so as to facilitate the positioning of the PCB board and ensure that the PCB board can move vertically into and out of the inner groove of the base 1 along the concave plates 4;

[0033] like Figure 2The lifting assembly shown includes a connecting rod 1 8 and a connecting rod 2 10. The connecting rod 1 8 is rotatably connected to the concave plate 4. Two groups of symmetrically arranged fixing seats 13 are fixedly connected to the bottom of the base 1 and the concave plate 4. A rotating shaft 1 9 is rotatably installed between the two groups of fixing seats 13 on the base 1. A rotating shaft 2 11 is rotatably installed between the two groups of fixing seats 13 on the concave plate 4. The free end of the connecting rod 1 8 is rotatably matched with the rotating shaft 1 9. The free end of the connecting rod 2 10 is rotatably matched with the rotating shaft 2 11. The connecting rod 1 8 and the connecting rod 2 10 are rotatably connected via the rotating shaft 3 14. When the rotating shaft 3 14 on both sides of the base 1 move relative to each other, the angle between the driving connecting rod 1 8 and the connecting rod 2 10 increases, pushing the concave plate 4 to move vertically upward; otherwise, the concave plate 4 is pushed to move vertically downward. This allows the PCB board placed on the concave plate 4 to enter and exit the groove of the base 1, making it easy to take and place the PCB board.

[0034] like Figure 2 The driving mechanism shown includes an L-shaped pull rod 3, a connecting rod 12, a fixed rod 7 and a spring 6. One end of the connecting rod 12 is fixedly connected to the vertical end of the pull rod 3. The horizontal end of the L-shaped pull rod 3 and the other end of the connecting rod 12 are respectively fixedly connected to two sets of rotating shafts 3 14 on the same side. The fixed rod 7 passes through the vertical end of the pull rod 3 and is fixedly connected to the base 1. The spring 6 is sleeved on the fixed rod 7. The fixed rod 7 is fixedly sleeved with a buffer plate 2. One end of the spring 6 is fixedly connected to the buffer plate 2, one end of the spring 6 is fixedly connected to the fixed rod 7, and the other end of the spring 6 is fixedly connected to the pull rod 3. The vertical ends of the pull rods 3 on both sides are pulled relatively close to each other, and the rotating shafts 3 14 are pulled toward each other through the horizontal end of the pull rod 3 and the connecting rod 12. Under the action of the connecting rod, the concave plate 4 is pushed up, and the spring 6 is stretched. When the pull rod 3 is released, under the reset action of the spring 6, the rotating shafts 3 14 on both sides move in opposite directions, and under the action of the connecting rod, the concave plate 4 is driven to descend. Compared with the prior art, in this embodiment, when taking and placing the PCB board, it is sufficient to operate the pull rod 3 once to move it closer, and a slide groove 102 is provided on the base 1, and the vertical end of the pull rod 3 passes through the slide groove 102. The pull rods 3 on both sides can be moved relatively closer by single-handed operation, which is convenient to operate.

[0035] Specifically, Figure 1 As shown, both ends of the concave plate 4 are fixedly connected to the limiting posts 5 , and the base 1 is provided with movable grooves 101 which are slidably matched with the limiting posts 5 to prevent the concave plate 4 from separating from the base 1 .

[0036] Working principle: when in use, one hand operates the pull rods 3 on both sides to move relatively close, and the horizontal end of the pull rod 3 and the connecting rod 12 are used to pull the rotating shaft three 14 to move toward each other, driving the angle between the connecting rod one 8 and the connecting rod two 10 to increase, pushing the concave plate 4 to move vertically upward, pushing the concave plate 4 to rise, and placing the PCB board on the concave plate 4. At this time, the spring 6 is stretched; after that, when the pull rod 3 is released, the rotating shaft three 14 on both sides moves in opposite directions under the reset action of the spring 6, and the concave plate 4 is driven to descend under the action of the connecting rod, and the PCB board is smoothly placed in the groove of the base 1. The pull rods 3 on both sides are operated once with one hand and then the PCB board is placed to complete the taking and placing of the PCB board in the groove of the base 1. The operation is simple and convenient.

[0037] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
