[0028] A disc-shaped sheet battery parts positioning and assembly machine, such as Figure 1 , Figure 7 , Figure 8As shown, it relates to an assembly machine for quickly positioning and assembling disc-shaped sheet battery parts 14 such as current collecting plates or current collecting sheets. Its structure mainly consists of a machine base 1, a bracket 2 installed on the machine base, a magnetic suspension track 10 installed on the machine base and located on one side of the bracket, a battery assembly trolley 12 that slides along the magnetic suspension track, a main shaft 3 vertically rotatedly installed in the bracket 2, an upper turntable 4 and a lower turntable 5 serially fixed on the main shaft, and a driving mechanism 6 installed in the machine base 1 and driving the main shaft 3 to drive the upper and lower turntables to rotate synchronously.

[0029] Among them, the machine base 1 is a rectangular frame structure formed by welding and fixing multiple steel rods and multiple steel plates to each other; the bracket 2 is a gate-shaped frame fixed to the top surface of the machine base 1, a slip ring assembly 31 is provided on the top of the main shaft 3, and a bearing seat 32 constituting the main shaft rotation installation is provided between the main shaft 3 and the top of the bracket 2, that is, between the top cross bar of the gate-shaped frame, and a shaft sleeve 33 constituting the main shaft rotation installation is provided between the main shaft 3 and the machine base 1.

[0030] The driving mechanism 6 includes a driving motor 61, a speed reducer 62 and a dividing and indexing rotary divider 63, and a gear set 64 meshing with the dividing and indexing rotary divider for power transmission is provided between the dividing and indexing rotary divider and the main shaft 3; thus, the power transmission process of the entire driving mechanism 6 is as follows: the driving motor 61 drives the pulley 65 to rotate, and the pulley transmits the power to the speed reducer 62 through the connected belt 66, and the speed reducer transmits the power to the dividing and indexing rotary divider 63 through the torque limiter 67 and the gear, and finally the dividing and indexing rotary divider transmits the power to the main shaft 3 through the gear set 64 meshing with each other, thereby driving the main shaft to form a dividing and indexing rotation.

[0031] The upper turntable 4 and the lower turntable 5 are both circular disks. In this embodiment, the outer diameter of the upper turntable 4 is larger than the outer diameter of the lower turntable 5 .

[0032] The lower turntable 5 is provided with a plurality of assembly holes 51 which are evenly distributed around the main shaft 3. Figure 3 As shown in the figure, six circumferentially evenly distributed circular holes are set on the lower turntable 5 as assembly holes 51, and the six assembly holes can respectively correspond to the indexing rotation of the lower turntable 5, that is, they are evenly divided into six angles and rotated in sequence. A nested and fixed guide sleeve 52 is provided in each assembly hole 51, and a plurality of circumferentially evenly distributed push block components 7 are provided on the periphery of each assembly hole. Figure 4 The figure shows that three push block assemblies 7 are evenly distributed around the circumference.

[0033] The upper turntable 4 is provided with a plurality of adsorption components 9 evenly distributed around the circumference with the main axis 3 as the center. The plurality of adsorption components form a one-to-one correspondence with the plurality of assembly holes 51, so the adsorption components 9 of this embodiment are also provided with corresponding six. Each adsorption component 9 can rise and reset or fall to adsorb the disc-shaped sheet battery part 14 and rotate and adjust to form a positioning with the assembly hole 51.

[0034] The adsorption assembly 9 includes a suction head 91 connected to an external air source, a suction nozzle 92 installed at the bottom of the suction head, a servo motor 94 arranged at the top of the suction head 91, and an electric cylinder 93 on one side of the suction head 91. The suction force of the suction nozzle 92 is provided by the air source external to the suction head 91. The servo motor 94 can drive the suction head 91 and the suction nozzle 92 to rotate synchronously, and the electric cylinder 93 can drive the suction head 91 and the suction nozzle 92 to move up and down synchronously.

[0035] Of course, this embodiment mainly uses the servo motor 94 and the electric cylinder 93, but in actual applications, the servo motor 94 and the electric cylinder 93 are different types of driving sources, so other driving sources that can reflect the functions of the servo motor 94 and the electric cylinder 93 can also be used.

[0036] The structures of the three push block assemblies 7 are exactly the same. Each push block assembly 7 includes a push mechanism 13 and a clamping block 71 installed in front of the push mechanism. The push mechanism 13 is fixed to the top surface of the lower turntable 5 through a cylinder plate, and can drive the clamping block 71 to translate inward or outward. In this way, when the disc-shaped sheet battery part 14 is placed between the three push block assemblies 7, the push mechanisms 13 of the three push block assemblies drive the clamping block 71 to translate inward synchronously, so that the outer circumference of the disc-shaped sheet battery part 14 can be pushed and contacted, thereby forming a quick alignment with the assembly hole 51.

[0037] At the same time, the bottom surface of the lower turntable 5 is also provided with a plurality of blocking components 8 surrounding the outer periphery of the assembly hole 51. Figure 5 , Figure 6 As shown, two relatively arranged blocking assemblies 8 are provided on the bottom surface of the lower turntable 5, and each blocking assembly includes a push mechanism 13 and a baffle 81 installed in front of the push mechanism. The push mechanism is fixed to the bottom surface of the lower turntable 5 through a cylinder plate, and can drive the baffle 81 to translate inward or outward; in this way, when the push mechanisms 13 of the two blocking assemblies 8 drive the baffle 81 to translate inward synchronously, it will directly block the bottom of the assembly hole 51, that is, block the bottom of the guide sleeve 52, or translate outward synchronously and leave the bottom of the assembly hole 51, that is, leave the bottom of the guide sleeve 52.

[0038] Moreover, the working state of the blocking component 8 is usually that when the adsorption component 9 has not adsorbed the disc-shaped sheet battery part 14, the baffles 81 of the two blocking components 8 will synchronously move inward to cover the bottom of the assembly hole 51. The purpose is to prevent the placed disc-shaped sheet battery part 14 from falling directly from the guide 52 when it is just in the positioning and centering; but when the adsorption component 9 descends to adsorb the disc-shaped sheet battery part 14, the baffles 81 of the two blocking components 8 will synchronously move outward to leave the bottom of the assembly hole 51, so as to rotate and adjust the disc-shaped sheet battery part 14 to form a positioning with the guide sleeve 52 in the assembly hole 51, and can continue to push the disc-shaped sheet battery part 14 through the guide sleeve 52 to form a mating assembly with the battery on the battery assembly cart 12.

[0039] The horizontal push mechanism 13 involved in the push block assembly 7 and the blocking assembly 8 usually adopts a horizontal push cylinder, and can also adopt other driving structures capable of horizontal push such as a horizontal push electric cylinder.

[0040] The positioning structure between the disc-shaped sheet battery part 14 and the guide sleeve 52 is that a plurality of positioning ribs 521 are provided on the inner circumferential wall of the guide sleeve 52, and each positioning rib is extended axially along the guide sleeve 52, and a plurality of positioning notches 141 are correspondingly provided on the outer circumference of the disc-shaped sheet battery part 14; the adsorption component 9 descends to adsorb the disc-shaped sheet battery part 14, and rotates to adjust the positions of the plurality of positioning notches 141 of the disc-shaped sheet battery part and the plurality of positioning ribs 521 of the guide sleeve 52 to correspond one to one, so that the disc-shaped sheet battery part 14 can be positioned and assembled in the guide sleeve 52, and at this time, the disc-shaped sheet battery part 14 can continue to be pushed down by the adsorption component 9 and directly pass through the guide sleeve 52.

[0041] In addition, a visual inspection module 11, that is, a CCD visual inspection system, is provided on the top of the base 1. The visual inspection module 11 is opposite to the assembly hole 51. For example, in the present embodiment, it is opposite to the bottom of the assembly hole 51, and is used to detect whether the disc-shaped sheet battery part 14 is positioned and assembled in the guide sleeve 52. For example, if it is detected that the disc-shaped sheet battery part 14 and the guide sleeve 52 are not positioned and assembled, the visual signal will be fed back to the adsorption component 9, and then the disc-shaped sheet battery part 14 will be driven by the adsorption component 9 to rotate and adjust to form a position with the guide sleeve 52 in the assembly hole 51.

[0042] The utility model uses a manipulator to place a disc-shaped sheet battery part 14 between a plurality of push block assemblies 8, which can be synchronously pushed inward by the plurality of push block assemblies to contact and align with the assembly hole 51, and then the adsorption assembly 9 corresponding to the assembly hole will cooperate to descend, and adsorb the disc-shaped sheet battery part 14 and rotate it to form a positioning with the guide sleeve 52 in the assembly hole 51, and then push the disc-shaped sheet battery part 14 to pass through the guide sleeve 52 and form a matching assembly with the battery on the battery assembly trolley 12; therefore, the assembly of the disc-shaped sheet battery part 14 can be completed continuously and efficiently by only driving the synchronous indexing rotation of the upper and lower turntables with the main shaft 3, and it can ensure that the battery structure achieves the advantages of high precision and high quality after assembly.

[0043] The above description is only a specific embodiment of the present invention. Those skilled in the art should understand that any structural design equivalent to this embodiment should be included in the protection scope of the present invention.
