[0002] Televisions are the most common household appliances. To avoid taking up too much space, televisions are typically mounted on a wall-mounted panel. Television panels are generally made of thin metal sheets, and due to their small thickness, they are often connected using rivet screws. The rivet process is usually completed on a rivet machine, but with a single rivet, multiple rivet screws are typically needed on a television panel. This requires multiple positioning and rivet processes, affecting assembly accuracy and reducing efficiency. Utility Model Content

[0026] like Figure 1-3 As shown, the present invention provides a riveting device for a television panel, comprising:

[0027] Two conveyor belts 1 are arranged in parallel along the horizontal direction, forming a perforated groove 16 between them. The front and rear sides of the TV panel 2 are placed on the two conveyor belts 1 and move to the right at a uniform speed. Side baffles 15 are provided on the front and rear sides of the conveyor belts 1 to limit the TV panel 2.

[0028] The screw feeding mechanism is located above the left side of the conveyor belt 1. The screw feeding mechanism includes a vertically arranged feeding pipe 5. The feeding pipe 5 is matched with the distribution position of the through hole 21 on the TV panel 2. The press screws 6 are stacked and arranged in the feeding pipe 5. The feeding pipe 5 is fixed by the bracket 51. A base plate 7 is provided at the lower opening of the feeding pipe 5. A first side push cylinder 71 is connected to one side of the base plate 7. A side push block 8 is provided on the outside of the feeding pipe 5. The side push block 8 is connected to the second side push cylinder 81. A side opening 52 is correspondingly machined on the side wall of the feeding pipe 5. The distance between the side push block 8 and the base plate 7 is greater than the length of one press screw 6 and less than the length of two press screws 6.

[0029] The first limiting plate 4 is located to the right of the screw feeding mechanism and inside the through groove 16. The lower part of the first limiting plate 4 is connected to the first lifting cylinder 41.

[0030] The guide plate 3 is located below the screw feeding mechanism. The guide plate 3 has guide holes 31 machined on it, which correspond one-to-one with the feeding pipe 5. The upper part of the guide holes 31 is chamfered. The front and rear ends of the guide plate 3 are connected to the side baffles 15. The distance between the guide plate 3 and the conveyor belt 1 is greater than the thickness of the TV panel 2.

[0031] The lower mold 9 is located below the right side of the conveyor belt 1. The upper part of the lower mold 9 has an inner hole 91, which is matched with the through hole 21. The depth of the inner hole 91 is greater than the length of the rivet screw 6. The front and rear width of the lower mold 9 is less than the width of the through groove 16. The lower mold 9 can move up and down.

[0032] The second limiting plate 10 is located on the right side of the lower mold 9. The lower part of the second limiting plate 10 is connected to the second lifting cylinder 101. The front and rear widths of the first limiting plate 4 and the second limiting plate 10 are both smaller than the width of the through groove 16.

[0033] The upper mold 13 is located directly above the lower mold 9. The lower part of the upper mold 13 is provided with a stamping rod 14 corresponding to the position of the inner hole 91. A pressure block 11 is provided between the stamping rods 14. The pressure block 11 is connected to the upper mold 13 through an elastic telescopic rod 12.

[0034] The device feeds rivet screws into the through holes on the TV panel through a screw feeding mechanism. Then, the lower and upper dies work together to rivet the rivet screws to the TV panel, completing the rivet process of the TV panel and rivet screws online, resulting in high assembly efficiency.

[0035] In practical use, for ease of understanding of this utility model, it will be described in conjunction with the accompanying drawings;

[0036] like Figure 5 The TV panel 2 shown has four through holes 21 punched out. The solution in this embodiment is used to rivet the rivet screws 6 to the through holes 21 for fixation.

[0037] During operation, the TV panels are placed at intervals on the conveyor belt and move at a constant speed from left to right. The initial positions of the first and second limiting plates are both higher than the conveyor belt. When the TV panel moves to the first limiting plate, the through holes on the TV panel, the guide holes on the guide plate, and the feeding pipe positions correspond one-to-one. The second side-push cylinder drives the side-push block to extend into the feeding pipe along its side opening. The side-push block presses against the second rivet screw from bottom to top for limiting. Then, the first side-push cylinder drives the base plate to move laterally, causing the lowest rivet screw in the feeding pipe to fall onto the guide plate and then along the guide hole into the through hole of the TV panel. The base plate then resets, the side-push block exits the feeding pipe, and the rivet screw in the feeding pipe falls onto the base plate for support. Next, the first lifting cylinder drives the first limiting plate to move downwards, with the pressure... The TV panel with the rivet screw continues to move to the right with the conveyor belt. When the TV panel moves out of the first limit plate, the first limit plate moves up and resets. The TV panel moves to the second limit plate, and the lower die moves up until it lifts the TV panel until it is no longer in contact with the conveyor belt. The lower part of the press-fit screw in the through hole extends into the inner hole of the lower die. Then the upper die moves down, and the pressure block presses the TV panel first. The elastic telescopic rod elastically contracts, and the stamping rod cooperates with the lower die to complete the riveting and fixing of the press-fit screw to the TV panel. The upper end of the press-fit screw is pressed into the upper edge of the through hole. After the riveting is completed, the upper and lower dies reset in sequence, and the TV panel is placed back on the conveyor belt. The second lifting cylinder drives the second limit block to move down, and the riveted TV panel moves to the right with the conveyor belt and is discharged. When the TV panel moves out of the second limit plate, the second limit plate moves up and resets.

[0038] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
