[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0025] Referring to Figures 1-4 , an embodiment provided by the present utility model: a hot riveting device for a PCB circuit board, including an operating table 1. A bracket 2 is fixedly connected to the rear side of the top of the operating table 1. A cylinder 3 is installed on the front side of the bottom of the bracket 2. The bottom driving end of the cylinder 3 is fixedly connected to a hot riveting plate 4. A limiting groove 5 is provided in the middle of the top of the operating table 1. The shape and size of the limiting groove 5 are adapted to the PCB circuit board, which is conducive to positioning and fixing the position of the circuit board, improving the processing stability, avoiding deviation. A threaded rod 17 is provided in the middle of the limiting groove 5. The top end of the threaded rod 17 is fixedly connected to a cross support frame 6, which is made of metal, conducive to conducting heat to the circuit board, accelerating the cooling after hot riveting, and improving the efficiency. The cross support frame 6 is slidably connected to the inner wall of the limiting groove 5. The outer wall of the threaded rod 17 is threadedly connected to a sleeve 7. The cross support frame 6 plays a limiting role, so that the threaded rod 17 moves in the vertical direction during the rotation of the sleeve 7. The top end of the sleeve 7 is rotatably connected to the rear side of the bottom of the operating table 1. A driven pulley 11 is fixedly connected to the outer wall of the sleeve 7. A rotating shaft 8 is rotatably connected to the front side of the bottom of the operating table 1. The top end of the rotating shaft 8 is fixedly connected to a dial rod 9. A driving pulley 10 is fixedly connected to the outside of the rotating shaft 8. The driving pulley 10 is connected to the driven pulley 11 through a belt. The bottom end of the rotating shaft 8 is connected to a motor 12. A bottom cover 14 is fixedly connected to the bottom side of the operating table 1. The motor 12 is installed inside the bottom cover 14. The PCB circuit board and the plastic parts are sequentially placed in the limiting groove 5 and placed on the cross support frame 6. At this time, the cross support frame 6 is hidden in the cross groove 13. Then, the cylinder 3 drives the hot riveting plate 4 to move down for hot riveting processing. After completion, the motor 12 drives the rotating shaft 8 to rotate, driving the driving pulley 10 to rotate. Through belt transmission, the driven pulley 11 and the sleeve 7 rotate accordingly. Due to the limitation of the cross support frame 6, the threaded rod 17 moves upward until the cross support frame 6 pushes the finished product out of the inside of the limiting groove 5. At this time, the lower half of the cross support frame 6 is located inside the limiting groove 5, and the upper half is located above the limiting groove 5, facilitating the dial rod 9 to dial the processed finished product driven by the rotating shaft 8, so that the processed finished product of the PCB circuit board slides out along the inclined plane 15, completing automatic discharging, without manual contact, avoiding scalding, and improving safety.

[0026] The lever 9 is crescent-shaped, which is convenient for shifting and avoids displacement of the circuit board during the process and failure of the shifting. The right side of the bottom cover 14 is fixedly connected with a slope 15, which is conducive to the slow drop of the PCB circuit board to avoid damage. The top and front and back sides of the slope 15 are fixedly connected with a shielding plate 16 to play a shielding and protective role to prevent the finished product from falling. The slope 15 is made of smooth stainless steel to reduce friction. A cross groove 13 is provided inside the limit groove 5. The cross groove 13 is adapted to the cross support frame 6 and can accommodate the cross support frame 6, so that the cross support frame 6 will not protrude during the hot riveting process, thereby affecting the processing.

[0027] Working principle: First, place the PCB circuit board and plastic parts into the limit groove 5 in turn and place them on the cross support frame 6. At this time, the cross support frame 6 is hidden in the cross groove 13. Then the cylinder 3 drives the hot riveting plate 4 to move down for hot riveting. After completion, the motor 12 drives the rotating shaft 8 to rotate, driving the active pulley 10 to rotate. Through the belt transmission, the driven pulley 11 and the sleeve 7 follow the rotation. Due to the limitation of the cross support frame 6, the threaded rod 17 moves upward until the cross support frame 6 pushes the finished product out of the limit groove 5. At the same time, the lever 9 drives the finished product under the drive of the rotating shaft 8, so that the finished PCB circuit board slides out along the inclined surface 15, completing automatic discharging without manual contact, avoiding burns and improving safety.

[0028] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
