[0066] Embodiment 1

[0067] Reference Figure 1 , Figure 2 , Figure 5As shown, the present invention discloses an automatic assembly line for capacitors 110, including an assembly line body 10, on which a plurality of positioning fixtures 11 are placed, and the assembly line body 10 is provided with a plurality of intercepting positioning mechanisms 12 along its transmission direction. Specifically, the assembly line body 10 is composed of a chain and a sprocket, and the transmission of the chain is driven by rotating the sprocket. The positioning fixtures 11 are placed on the two chains and can move horizontally with the transmission of the chains. The assembly line body 10 comprises a first assembly line body 101 and a second assembly line body 102 which are arranged parallel to each other, and a first conveying mechanism 103 and a second conveying mechanism 104 of the positioning fixture 11 are respectively arranged at both ends of the assembly line body, wherein the first assembly line body 101 is provided with a detection component, and the detection component comprises a first sensor and a second sensor, the first sensor is arranged in the middle of the first assembly line body 101, and is used to detect whether the housing 1101 on the positioning fixture 11 is placed in place, and the second sensor is arranged on a side of the first assembly line body 101 close to the first conveying mechanism 103, when it is detected that the positioning fixture 11 moves to the leftmost end of the first assembly line body 101, the first conveying mechanism 103 moves the positioning fixture 11 from the first assembly line body 101 to the second assembly line body 102, and the first conveying mechanism 103 moves the positioning fixture 11 from the first assembly line body 101 to the second assembly line body 102, and the second conveying mechanism 104 moves the positioning fixture 11 from the first assembly line body 101 to the second assembly line body 102. The first conveying mechanism 103 and the second conveying mechanism 104 respectively include a slide rail 1041, a conveyor belt 1042, a moving cylinder 1043 and a buffer cylinder 1044. The positioning fixture 11 moves from the assembly line body 10 on one side to the conveyor belt 1042. The moving cylinder 1043 pushes the tray to move on the slide rail 1041, and then the positioning fixture 11 is pushed from the conveyor belt 1042 to the assembly line body 10 on the other side by rotating the transmission belt in the opposite direction. Buffer cylinders 1044 are provided at both ends of the slide rail 1041 along the length and on the side of the conveyor belt 1042 away from the assembly line body 10 to buffer the impact during movement. The first conveying mechanism 103 and the second conveying mechanism 104 make the first assembly line body 101 and the second assembly line body 102 form a closed-loop transmission, saving logistics manpower and space.

[0068] Reference Figure 4 As shown, the positioning fixture 11 includes a base plate 111, a guide rail 112 is installed on the base plate 111, two positioning blocks 113 are slidably arranged on the guide rail 112, and an adjustable fixing mechanism is arranged on one side of the positioning block 113, the adjusting mechanism includes a fixing block 114 fixed on the base plate 111 and a latch 115 fixed on one end face of a slider 722, a plurality of through holes are opened on the fixing block 114, and the distance between the two sliders 722 can be adjusted by adjusting the two through holes fixed by the latch 115 at different positions to meet the fixation of the housing 1101 of different sizes.

[0069] Reference Figure 2 , Figure 3As shown, the intercepting and positioning mechanism 12 is arranged between the two chains, and the intercepting and positioning mechanism 12 includes a lifting cylinder 121. The piston rod of the lifting cylinder 121 is provided with a roller 123 that can roll along the moving direction of the positioning fixture 11. In the initial state, the piston rod of the lifting cylinder 121 pushes the roller 123 upward. When the positioning fixture 11 is transmitted on the two chains, the roller 123 intercepts the positioning fixture 11, so that the positioning fixture 11 will not move with the transmission of the assembly line body 10. Each mechanism on the assembly line body 10 performs an installation operation on the shell on the positioning fixture 11. After the installation operation is completed, the piston rod of the lifting cylinder 121 retracts downward, and the positioning fixture 11 enters the installation of the next mechanism with the transmission of the assembly line body 10. The intercepting and positioning mechanism 12 can temporarily fix the positioning fixture 11, so that each mechanism can install the shell 1101 on the positioning fixture 11.

The first feeding mechanism 21 moves the lower positioning sleeve 1102 to a specified position, and the lower positioning sleeve 1102 is moved to the core fixing plate 23 by the first picking robot 22, and then moved from the core fixing plate 23 to the shell 1101. Specifically, the first feeding mechanism 21 includes a first vertical conveyor belt 211 and a first horizontal conveyor belt 212. The upper positioning sleeve 1103 rises vertically upward from the first vertical conveyor belt 211, and then slides to the first horizontal conveyor belt 212. On the flat conveyor belt 212, it is conveyed to the side close to the first picking robot 22 through the first horizontal conveyor belt 212. The first picking robot 22 includes a first suction cup 221 and a second suction cup 222. The upper positioning sleeve 1103 is fixed by the first suction cup 221 and moved to the centering plate 23 for fixing. The centering plate 23 is composed of two clamping blocks. The two clamping blocks clamp the lower positioning sleeve 1102 for positioning to avoid the upper positioning sleeve 1103 and the housing 1101 being misaligned and unable to be installed in the housing 1101. The second suction cup 222 sucks the lower positioning sleeve 1102 onto the shell on the positioning fixture 11, so that the lower positioning sleeve 1102 is moved into the housing 1101. Among them, the size of the lower positioning sleeve 1102 is adjusted according to the size of the housing 1101, and the first vertical conveyor belt 211 and the first horizontal conveyor belt 212 can be suitable for lower positioning sleeves 1102 of different sizes.

Specifically, the second feeding mechanism 51 includes a second vertical conveyor belt 511 and a second horizontal conveyor belt 512. The upper positioning sleeve is conveyed from the second vertical conveyor belt 511 to the second horizontal conveyor belt 512.

Furthermore, the glue-spraying assembly 52 includes a turntable 521, on which four stepped fixtures 522 are arranged. The use of a circular fixture with steps can be fixed according to different sizes of the upper positioning sleeve 1103. A detection flip mechanism 524 and an automatic glue dispenser 523 are respectively arranged near the turntable 521. The detection flip mechanism 524 includes a rotating motor 5241, a clamping claw 5242 and a first detection CCD (not shown in the figure). Specifically, the second picking manipulator 53 places the upper positioning sleeve 1103 in the empty stepped fixture 522, and the turntable 521 rotates through a station to move the upper positioning sleeve 1103. The detection flipping mechanism 524 is moved to the detection flipping mechanism 524, and the first detection CCD (not shown in the figure) is used to check whether the upper positioning sleeve 1103 is facing up. If it is not facing up, the upper positioning sleeve 1103 is clamped by the clamping claw 5242 and the rotating motor 5241 drives the clamping claw 5242 to drive the upper positioning sleeve 1103 to rotate, so that the upper positioning sleeve 1103 is facing up and transferred to the next workstation. The transport robot 54 clamps the upper positioning sleeve 1103 and adjusts the height. The automatic glue dispensing machine 523 applies glue to both sides of the upper positioning sleeve 1103. Finally, the transport robot 54 moves the upper positioning sleeve 1103 to the upper end of the shell 1101 and fixes it.

[0072] Furthermore, the second assembly line body 102 is provided with a lower locating sleeve clamping mechanism 30 and a lower locating sleeve detection mechanism 40 between the lower locating sleeve mounting mechanism 20 and the upper locating sleeve mounting mechanism 50. Specifically, the lower locating sleeve clamping mechanism 30 includes a first clamping cylinder 301 and a first pressure plate 302. The first pressure plate 302 is fixed on the piston rod of the first clamping cylinder 301. The first clamping cylinder 301 pushes the first pressure plate 302 to clamp the lower locating sleeve 1102 on the bottom of the outer shell 1101; the lower locating sleeve detection mechanism 40 includes a second detection CCD. The lower locating sleeve 1102 is clamped on the outer shell 1101 by the lower locating sleeve clamping mechanism 30, and the second detection CCD detects whether it is clamped.

Specifically, the pressing detection mechanism 61 includes a third detection CCD, a second pressing cylinder 611 and a second pressure plate 612. The piston rod of the second pressing cylinder 611 The second pressure plate 612 is fixed, and the second clamping cylinder 611 pushes the second pressure plate 612 downward. The third detection CCD (not shown in the figure) is set on the second pressure plate 612. After the second pressure plate 612 presses down the upper positioning sleeve 1103, the third detection CCD (not shown in the figure) detects the outer shell 1101 equipped with the upper positioning sleeve 1103. If the third detection CCD detects that it is a defective product, the third picking robot 63 clamps the upper positioning sleeve 1103 connected to the outer shell 1101 and the lower positioning sleeve 1102, removes it from the positioning fixture 11, and places it on the defective product conveyor belt 1042.

[0074] Reference Figure 2 As shown, the labeling mechanism 90 is used to label the outer shell 1101, and includes a labeling machine and a label pressing cylinder. The labeling machine labels the outer shell 1101, and presses the label on the outer shell 1101 through the label pressing cylinder. The labeling machine labels the outer shell 1101 one by one, and the label pressing cylinder further presses the label on the outer shell 1101, thereby further pressing the label.
