Description

Technical Field

[0001] This utility model relates to the field of battery technology, and in particular to a cap centering mechanism. Background Technology

[0002] In the battery manufacturing process, some parts need to be assembled, such as Figure 1 As shown, during assembly, the cap 100 needs to be placed into the center hole of the top cover 200. In order to prevent the cap 100 from rubbing against the top cover 200 during the process of placing the cap 100 into the center hole 201 of the top cover 200, accurate positioning is required. Traditional equipment mostly uses a suction nozzle to pick up the cap 100 and then place the cap 100 into the center hole 201 of the top cover 200. The head of the suction nozzle is made of a flexible material and will swing slightly, making it difficult for this traditional structure to ensure that the cap 100 is accurately placed into the center hole 201 of the top cover 200. Utility Model Content

[0003] The purpose of this invention is to provide a cap centering mechanism with accurate positioning.

[0004] To achieve the above objectives, the technical solution of this utility model is:

[0005] This utility model is a cap centering mechanism, including a fixed base, a cylinder, a pressure rod, a shift fork, a nozzle rod, a sleeve assembly, multiple centering grippers, multiple return springs, and a suction nozzle;

[0006] The fixed base is installed on the machine tool, the cylinder body of the cylinder is installed on the fixed base, the upper part of the nozzle rod is movably inserted into the guide hole of the fixed base, the piston rod end of the cylinder is connected to one side of the shift fork through the pressure rod, the other side of the shift fork is movably sleeved on the middle part of the nozzle rod and connected to the sleeve assembly, the sleeve assembly is movably sleeved on the middle part of the nozzle rod, the lower part of the sleeve assembly abuts against the outside of multiple centering jaws, the upper ends of the multiple centering jaws are respectively hinged to the outer wall of the lower part of the nozzle rod, the lower ends of the centering jaws extend downward and are located outside the suction nozzle, the upper end of the suction nozzle is fixed to the lower end of the nozzle rod, and multiple return springs are respectively installed in the spring holes of the lower part of the nozzle rod, the outer ends of the return springs extend out of the outer wall of the nozzle rod and abut against the middle part of the centering jaws.

[0007] The sleeve assembly includes a sleeve, two gun rings, and a buffer pad; the sleeve is movably sleeved on the middle of the air nozzle rod, the lower part of the inner wall of the sleeve abuts against the outer side of multiple centering jaws, and one gun ring, the buffer pad, and the other gun ring are sequentially fixedly sleeved on the upper part of the sleeve.

[0008] The buffer pad is a rubber pad.

[0009] The upper end of the centering gripper has a hemispherical boss, which is movably fitted into a spherical groove on the outer wall of the nozzle rod. With the above solution, this utility model includes a fixed base, a cylinder, a pressure rod, a shift fork, a nozzle rod, a sleeve assembly, multiple centering grippers, multiple return springs, and a suction nozzle. During operation, the suction nozzle picks up the cap, and then the cylinder drives the shift fork downwards via the pressure rod. The shift fork drives the sleeve assembly downwards along the nozzle rod. The lower part of the sleeve assembly slides against the outside of the multiple centering grippers and drives the multiple centering grippers to retract inwards. The lower part of the multiple centering grippers clamps the outer circle of the cap, accurately positioning the cap, thus providing the advantage of accurate positioning.

[0010] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Attached Figure Description

[0013] Figure 3 This is a cross-sectional view of the present invention. Detailed Implementation

[0014] like Figure 2 , Figure 3 As shown, this utility model is a cap centering mechanism, including a fixed base 1, a cylinder 2, a pressure rod 3, a shift fork 4, a nozzle rod 5, a sleeve assembly 6, multiple centering grippers 7, multiple return springs 8, and a suction nozzle 9.

[0015] The fixed base 1 is mounted on the machine tool (not shown in the figure). The cylinder body of the cylinder 2 is mounted on the fixed base 1. The upper part of the nozzle rod 5 is movably inserted into the guide hole 11 of the fixed base 1. The piston rod end of the cylinder 2 is connected to one side of the shift fork 4 through the pressure rod 3. The other side of the shift fork 4 is movably sleeved on the middle part of the nozzle rod 5 and connected to the sleeve assembly 6. The sleeve assembly 6 is movably sleeved on the middle part of the nozzle rod 5. The lower part of the sleeve assembly 6 abuts against the outside of the multiple centering jaws 7. The upper ends are respectively hinged to the outer wall of the lower part of the air nozzle rod 5. In this embodiment, there are three centering claws 7, which are equally spaced and spaced apart. The lower end of the centering claw 7 extends downward and is located outside the suction nozzle 9. The upper end of the suction nozzle 9 is fixed to the lower end of the air nozzle rod 5. The middle part of the air nozzle rod 5 has an air passage 51, which is connected to an air source. Multiple return springs 8 are respectively installed in the spring hole 52 at the lower part of the air nozzle rod 5. The outer end of the return spring 8 extends out of the outer wall of the air nozzle rod 5 and abuts against the middle part of the centering claw 7.
