[0033] According to the assembly device provided in the application, the first feeding mechanism 100 comprises a clamping assembly 110 and a positioning assembly 120, at least part of the clamping assembly 110 is movably arranged along a predetermined track to clamp the first workpiece and place the first workpiece on the positioning assembly 120, the positioning assembly 120 is provided with a positioning part 121, at least part of the first workpiece is attached to the positioning part 121, and then the first workpiece is positioned; the second feeding mechanism 200 is arranged on the side of the first feeding mechanism 100, and the position of the second feeding mechanism 200 is movably arranged to convey the second workpiece; the first transfer mechanism 300 is movably arranged between the first feeding mechanism 100 and the second feeding mechanism 200, and the first transfer mechanism 300 is used to clamp the first workpiece in the positioning assembly 120 and place the first workpiece to the first predetermined mounting position on the second workpiece; the third feeding mechanism 400 is arranged on the side of the second feeding mechanism 200 away from the first feeding mechanism 100, and the third feeding mechanism 400 is used to convey the third workpiece; the second transfer mechanism 500 is movably arranged between the second feeding mechanism 200 and the third feeding mechanism 400, and the second transfer mechanism 500 is used to suck the third workpiece and mount the third workpiece to the second predetermined mounting position on the second workpiece, so that the first workpiece and the second workpiece are connected through the third workpiece. Through the automatic operation of the first feeding mechanism 100 and the second feeding mechanism 200, the automatic feeding of the first workpiece and the second workpiece is realized, the positioning part 121 on the positioning assembly 120 ensures the accurate position of the first workpiece during clamping and placing, and the automatic transfer and mounting of the first transfer mechanism 300 and the second transfer mechanism 500 can accurately mount the first workpiece and the third workpiece to the predetermined position on the second workpiece, greatly reducing the assembly error and improving the overall quality of the product.

[0034] Because the positions of the second feeding mechanism 200 and the first transfer mechanism 300 are movably arranged, the assembly requirements of different workpieces can be met, even if the specifications of the workpieces change in the production line, the flexibility can be adjusted to maintain the continuity and efficiency of the assembly. Automatic feeding and assembly reduce the dependence on manpower, reduce labor costs, and also avoid potential problems caused by improper manual operation, such as assembly errors and damaged workpieces.

[0035] As Figure 3As shown, the first feeding mechanism 100 further comprises a conveying platform 130 for conveying the material frame 600, and a first lifting assembly 140 arranged at the end of the conveying platform 130. The first lifting assembly 140 comprises a first supporting component 141 movably arranged in the vertical direction. After the conveying platform 130 conveys the material frame 600 to the first supporting component 141, the first supporting component 141 drives the material frame 600 to move to a clamping position, and the clamping assembly 110 clamps the first workpiece at the clamping position. By arranging the conveying platform 130 and the first lifting assembly 140, the automatic conveying and positioning of the ignition coil material frame 600 are realized, which greatly improves the automation degree of the assembly line, reduces manual intervention, and improves the efficiency of the production line. The first supporting component 141 can be accurately moved in the vertical direction, ensuring that the material frame 600 is accurately conveyed to the clamping position of the clamping assembly 110, which helps to improve the assembly accuracy, reduce assembly errors, and thus improve product quality. The movable design of the first supporting component 141 enables the feeding mechanism to adapt to assembly lines of different heights, increasing the flexibility of operation and facilitating coordination with other equipment of the production line.

[0036] In specific implementation, as shown in the drawings, Figure 5 As shown, the conveying platform 130 comprises a plurality of conveying rollers 131 rotatably arranged around their own axes to convey the material frame 600. The first lifting assembly 140 further comprises a first lifting bracket 142 arranged at the end of the plurality of conveying rollers 131, and a first lifting slide rail 143 arranged on the first lifting bracket 142 and extending in the height direction of the first lifting bracket 142. The first supporting component 141 is arranged on the first lifting slide rail 143 and slidably arranged along the extension direction of the first lifting slide rail 143. The first lifting assembly 140 can automatically lift and lower the first supporting component 141, thereby realizing the height adjustment of the material frame 600 to accurately align the working position of the ignition coil automatic feeding system. This avoids the labor intensity of manually carrying the material frame 600 and reduces human errors during operation. The plurality of conveying rollers 131 are rotatably arranged around their own axes to ensure the stability of the material frame 600 during conveying, reduce wear and noise, and improve the continuity and efficiency of work. The first supporting component 141 is slidably arranged along the extension direction of the first lifting slide rail 143, which cooperates with the first lifting slide rail 143 extending in the height direction of the first lifting bracket 142 to realize the precise vertical positioning of the material frame 600, ensuring the accuracy of the ignition coil during secondary positioning. By adjusting the position of the first supporting component 141 on the first lifting slide rail 143 and the height of the first lifting bracket 142, the system can adapt to material frames 600 of different sizes and shapes, improving the assembly adaptability of various ignition coil models.

The setting of the transition position makes the first workpiece have an intermediate carrying step between clamping and placing, which not only improves the continuity of operation, but also ensures the smooth transition between the material frame 600 and the first feeding mechanism 100, reducing the collision between equipment or operation errors caused by directly moving the material frame. The movable design of the first clamping assembly 150 along the horizontal direction and the setting of the carrying plate 160 optimize the spatial layout of the production line, so that the material frame 600 can be moved to the carrying plate without interfering with the operation of other equipment, improving the smoothness of the production process and the space utilization efficiency.

Through the relative arrangement of the third clamping piece 171 and the fourth clamping piece 172, the second clamping assembly 170 can accurately control the clamping force and position of the frame 600, avoiding the shaking or falling of the frame 600 during movement, thereby ensuring the stability and safety of the feeding process. The introduction of the second lifting assembly 180 makes the feeding and discharging operation of the frame 600 fully automated without manual intervention. When the second supporting part 181 is in the supporting position, it is in precise butt joint with the carrying plate 160, and the second clamping assembly 170 can smoothly place the frame 600 on the carrying plate 160, realizing the automatic discharging of the empty frame.

[0053] As shown in Figure 9 , it is the working process of the assembly equipment of the present application, mainly divided into ignition coil automatic feeding process, first robot assembly system and second robot assembly system;

[0054] Specifically, the AGV distributes the materials (ignition coils), the material frame is horizontally conveyed to the position by the roller way, the material frame is raised to the material taking position by the lifting mechanism, the system judges the type of the ignition coil to be installed, the 3D vision system 1 moves to the position, the 3D vision takes a picture and guides the SCARA robot to grab and place in the positioning assembly, the positioning assembly is stretched out, waiting for the first assembly robot to grab the ignition coil from the positioning assembly; the positioning assembly is retracted;

[0055] At the same time, the engine is conveyed to the position by the plate chain conveying line; the engine model is read through the MES system; at this time, the engine model is read through the MES system, and it is determined which type of bolt to be used;

[0056] The 3D vision system 2 positions the installation hole position coordinates of the engine, at this time, the first assembly robot grabs the ignition coil from the positioning assembly and places it in the installation hole; waiting for the second assembly robot to fix it with a bolt; after the engine is installed with 6 ignition coils, it is released;
