The second slider 102 is provided with a top block 104, which slides on the two horizontal surfaces of the upper end of the second slider 102 to control the up and down movement of the top block 104.

[0051] Reference manual attached Figure 7-10 As shown, the backplate machine also includes a backplate storage rack 5 and a storage and pushing device 9;

[0052] The back panel storage rack 5 includes a back panel storage trough 51. A horizontally movable limiting plate 53 is provided below the back panel storage trough 51. The limiting plate 53 is threadedly connected to a rocker arm 52. By rotating the rocker arm 52, the limiting plate 53 is controlled to move horizontally, thereby limiting the back panel and preventing the back panel from tipping over.

[0053] The material pushing device 9 is located below the back plate storage rack 5, and the material pushing device 9 includes a pushing motor 91 and a back plate pushing block 92 connected to the pushing motor 91. The back plate pushing block 92 is used to push the bottom back plate of the back plate storage groove 51 to one side.

[0054] Specifically, the receiving and pushing device 12 includes:

[0055] Material receiving guide rail 121 is disposed on the frame 1;

[0056] The first receiving slider 122 slides on the receiving guide rail 121.

[0057] A first receiving motor 123 is disposed on a first receiving slider 122. A second receiving slider 124 is disposed on the first receiving slider 122. The first receiving motor 123 is used to control the second receiving slider 124 to move on the first receiving slider 122.

[0058] The second receiving motor 125 is mounted on the second receiving slider 124. The second receiving slider 124 is also provided with a back plate fixing frame 126. The second receiving motor 125 is connected to the back plate fixing frame 126. The second receiving motor 125 is used to control the back plate fixing frame 126 to rotate on the second receiving slider 124. The back plate fixing frame 126 is used to receive the back plate pushed by the material storage and pushing device 9 and move the back plate to the material distribution device 7 for processing.

[0059] The receiving and pushing device 12 can receive the back plate delivered by the storage and pushing device 9, and deliver the back plate to the material distribution device 7 between the pressing device 4 and the lifting device 10 for the installation of hardware accessories. After the hardware accessories are installed, they are delivered to the next mechanism.

[0060] Specifically, the backplate machine also includes a finished product conveying device 6, which is disposed on one side of the receiving and pushing device 12. The finished product conveying device 6 includes:

[0061] Conveyor belt 63;

[0062] Third cylinder 62;

[0063] The receiving tray 61 is inclined in the direction of conveying the conveyor belt 63, and the receiving tray 61 is connected to the third cylinder 62. When the finished product back plate falls onto the receiving tray 61, the finished product back plate can slide onto the conveyor belt 63 because the receiving tray 61 is in an inclined state.

[0064] Working principle: Hardware parts are fed into the material distribution device 7 and onto the turntable 71 via the hardware parts vibrating plate and the linear vibrating guide rail 21. The turntable 71 has 4-8 hardware parts fixed stations 72 (the number of stations depends on the product shape). One hardware part is conveyed from the linear vibrating guide rail 21 to the hardware parts fixed station 72 on the turntable 71. The hardware parts fixed station 72 rotates to be directly below the pressing device 4. At the same time, the rivets in the rivet vibrating plate are fed into the chuck in the rivet cavity 47 on the pressing device 4 via the rivet guide rail 31. There is a sensor control device on both the hardware parts linear vibrating track 21 and the rivet track 31, and only one product can be fed at a time.

[0065] Multiple back panels are placed into the back panel storage rack 5. The storage and pushing device 9 is activated to push one back panel onto the receiving and pushing device 12. After the back panel fixing bracket 126 locks the back panel in place, the receiving and pushing device 126 pushes the back panel to the right and then towards the distributing device 7, delivering the back panel below the pressing device 4. At the same time, the lifting device 10 pushes upward and the pressing device 4 presses down, riveting the hardware accessories on the hardware accessory fixing station 72 onto the back panel. When the first hardware accessory is riveted, both the back panel fixing bracket 126 on the receiving and pushing device 12 and the hardware accessory fixing station 72 on the turntable 71 automatically rotate. The rotation allows the hardware on the second hardware fixing station 72 to align with the position on the back plate where the second hardware needs to be installed for installation and fixing. When all the work at the hardware fixing stations is completed, the receiving and pushing device 12 automatically returns to its initial position, and the finished product conveying device 6 extends behind the receiving and pushing device 12. At the same time, the storage and pushing device 9 pushes out an unfinished back plate and pushes the finished back plate onto the finished product conveying device 6. The finished product conveying device 6 then returns to its original position. The receiving plate 61 of the finished product conveying device 6 is inclined, so the finished back plate slides directly onto the conveyor belt 63, and the conveyor belt delivers the finished product into the basket.

[0066] Each step of the above actions is performed according to the microcomputer control program to deliver the hardware accessories. The backplate is pushed out to the receiving and pushing device 12 and then sent to the distributing device 7. At the same time, the lifting device 10 lifts up and the pressing device 4 presses down to attach the hardware accessories, completing the first hardware product. The backplate fixing frame 126 will then retract and rotate to the second workstation. The distributing device 7 will simultaneously rotate and send the second hardware product to the lifting device 10 for lifting up and the pressing device 4 for pressing down. This process continues until the hardware accessories are attached to the backplate. The receiving and pushing device 12 pushes out the backplate and simultaneously pushes the attached backplate onto the finished product conveying device 6. Each workstation is equipped with a sensor. The next action will only proceed after the previous action has been accurately detected and completed by the sensor. If a product is not delivered, the control microcomputer will issue an error alarm and stop the next action.

[0067] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0068] This technical solution provides an automatic back panel installation machine for picture frame hardware accessories, including a frame, a material distribution device, a hardware accessory conveying device, a pressing device, a rivet conveying device, an upper lifting device, and a receiving and pushing device.
