Description

Technical Field

[0001] The present invention relates to the field of lithium battery manufacturing, and particularly to a rubber plug feeding and hole selection device and method thereof. Background Art

[0002] In the prior art, the equipment for manufacturing lithium batteries such as lithium batteries, aluminum electrolytic lithium batteries, and super lithium batteries is an assembly machine. For example, the Chinese utility model patent: Patent No. ZL201920221009.3, titled "An Automatic Lithium Battery Assembly Machine", discloses an assembly machine capable of automatically producing and assembling lithium batteries. The rubber plug transfer device of the existing assembly machine rotates the rubber plug to transfer it from the feeding station, the detection station, and the assembly to the outer shell station in sequence. When reaching the detection station, a probe is inserted downward into the rubber plug hole to detect whether the position of the rubber plug is accurate (the accurate position of the rubber plug is for the lead to extend from the rubber plug hole when installing the product subsequently). When the rubber plug is placed accurately, the probe can be normally inserted into the rubber plug hole. When the rubber plug is placed inaccurately, the probe cannot be inserted into the rubber plug hole. The disadvantage of this detection method is that the probe may scratch the rubber plug when colliding with it. Summary of the Invention

A plurality of rubber plug limiting sleeves are installed on the disc. The rubber plug feeding mechanism drives the rubber plug into the rubber plug limiting sleeve. The disc rotates to make the rubber plug limiting sleeve pass through the hole position detection mechanism and the rubber plug rotation and position adjustment mechanism. The hole position detection mechanism detects the hole position of the rubber plug in the rubber plug limiting sleeve, and the rubber plug rotation and position adjustment mechanism drives the rubber plug to rotate and adjust the position according to the detection result.

[0005] As a preferred solution of the present invention, the hole position detection mechanism is a CCD camera or a photoelectric inductor.

[0006] As a preferred solution of the present invention, the rubber plug rotation and position adjustment mechanism includes a roller, a roller motor, a moving plate, and a moving power component. The roller motor drives the roller to rotate. The roller motor is installed on the moving plate. The moving power component drives the moving plate to move forward to make the roller approach the rubber plug, and the roller drives the rubber plug to rotate.

[0007] As a preferred solution of the present invention, the rubber plug limiting sleeve includes a sleeve body and a rotating shaft.

The bottom end of the pressing rod extends directly above the discharge hole.

[0009] As a preferred embodiment of the present invention, when the opening and closing block moves up, the two movable pieces move inward to block the discharge hole. When the opening and closing block moves down, the two movable pieces move outward to open the discharge hole. The discharge hole is vertically arranged. The rubber stopper stopper is further provided with a horizontally arranged feeding groove, and the feeding groove communicates with the discharge hole. The pressing rod extends into the feeding groove, and the vibrating bowl drives the rubber stopper to enter the feeding groove.

[0010] As a preferred embodiment of the present invention, a linear bearing is installed inside the lifting block. The upper part of the pressing rod passes through the linear bearing. The upper end of the spring abuts against the linear bearing and the lower end abuts against the limiting piece.

[0022] The following further describes the detailed embodiment of the present invention in conjunction with the accompanying drawings:

[0023] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the indicated position or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0024] In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] Such as Figures 1 to 3As shown in the figure, a rubber stopper feeding and hole selection device includes a disk 1, a rubber stopper limiting sleeve 2, a rubber stopper feeding mechanism 3, a hole position detection mechanism 4, and a rubber stopper rotation and position adjustment mechanism 5. A plurality of rubber stopper limiting sleeves 2 are installed on the disk 1, and the rubber stopper limiting sleeves 2 are arranged circumferentially around the central axis of the disk. The rubber stopper feeding mechanism drives the rubber stoppers into the rubber stopper limiting sleeves. The rotation of the disk causes the rubber stopper limiting sleeves to pass through the hole position detection mechanism and the rubber stopper rotation and position adjustment mechanism. The disk 1 is driven by a divider to rotate and index, which is a prior art. The rotation of the disk 1 causes the rubber stoppers to lean against the hole position detection mechanism 4 and the rubber stopper rotation and position adjustment mechanism. The hole position detection mechanism 4 is located above, and the hole position detection mechanism 4 detects the hole positions of the rubber stoppers in the rubber stopper limiting sleeves. The rubber stopper rotation and position adjustment mechanism 5 drives the rotation and position adjustment of the rubber stopper 6 according to the detection results.

[0026] Specifically, the hole position detection mechanism 4 is a CCD camera or a photoelectric sensor. The hole position detection mechanism 4 identifies the hole positions of the rubber stoppers and sends an adjustment signal to the rubber stopper rotation and position adjustment mechanism 5.

[0027] As Figure 3 shown in the figure, the rubber stopper rotation and position adjustment mechanism 5 includes a roller 21, a roller motor 52, a moving plate 53, and a moving power member. The moving power member can be a cylinder, an oil cylinder, or a servo electric cylinder, and its function is to move the moving plate 53. The roller motor 52 drives the roller 21 to rotate. The roller motor 52 is installed on the moving plate 53. The moving power member drives the moving plate 53 to move forward so that the roller 21 approaches the rubber stopper. After the roller frictionally contacts the rubber stopper limiting sleeve 2, the rotation of the roller 21 can drive the rotation of the rubber stopper 6.

[0028] As Figure 4 shown in the figure, the rubber stopper limiting sleeve 2 includes a sleeve body 21 and a rotating shaft 22. A groove 23 for placing the rubber stopper is provided at the center of the sleeve body 21. An annular groove is provided on the outer peripheral side of the sleeve body 21. The rotating shaft 22 is connected to the lower part of the sleeve body 21, and the rotating shaft 22 is rotatably connected to the disk 1.

A support seat 32 is installed above the fixing plate 31, and a lifting block 33 is slidably installed in front of the support seat 32. The lifting power member drives the lifting block 33 to move up and down. A pressing rod 34 is movably sleeved in the lifting block 33. A limiting piece 35 is installed around the pressing rod 34. The spring 36 is sleeved on the pressing rod 34. When the lifting block 33 moves down, the pressing rod 34 is driven to move down by the spring 36. A fixing connection is made between the lower part of the pressing rod 34 and the opening and closing block 37. A connecting piece 38 is hinged to each of the left and right sides of the opening and closing block 37. A rubber stopper stopper 310 is installed in front of the fixing plate 31. The rubber stopper stopper 310 is located above the disk. The rubber stopper stopper 310 is provided with a discharge hole 311 for a single rubber stopper to pass through, that is, the aperture of the discharge hole 311 is slightly larger than the outer diameter of the rubber stopper 6. The vibrating disk 7 drives the rubber stopper 6 to enter the discharge hole 311 from the side. A movable piece 39 is slidably installed on each of the left and right sides of the rubber stopper stopper 310. The left connecting piece 38 is hinged to the left movable piece 39, and the right connecting piece 38 is hinged to the right movable piece 39. The bottom end of the pressing rod 34 extends directly above the discharge hole 311.

[0030] Specifically, the pressing rod 34 and the opening and closing block 37 are in interference fit. When the pressing rod 34 moves, the opening and closing block 37 also moves. When the opening and closing block 37 moves up, the two movable pieces 39 move inwards to block the discharge hole 311. When the opening and closing block 37 moves down, the two movable pieces 39 move outwards to open the discharge hole 11. The movable piece 39 includes a blocking piece part 391 and a hinged part 392 which are integrally connected. The blocking piece part 391 is located inside the rubber stopper stopper 310. The blocking piece part 391 is used to block the discharge hole. The hinged part 392 is connected above the blocking piece part 391. The hinged part 392 extends out of the rubber stopper stopper 310. The hinged part 392 is provided with a hinge hole. The hinged part 392 is hinged to the connecting piece 8 through a hinge shaft inserted into the hinge hole and the connecting piece.

[0031] Specifically, the discharge hole 311 is vertically arranged. The rubber stopper stopper 310 is further provided with a horizontally arranged feeding groove 312. The feeding groove 312 communicates with the discharge hole 311. The pressing rod 34 extends into the feeding groove 312. The vibrating disk can orderly drive the rubber stopper into the feeding groove 312 through the side opening of the feeding groove 312. A linear bearing 313 is installed inside the lifting block 33. The upper part of the pressing rod 34 passes through the linear bearing 312. The upper end of the spring 36 abuts against the linear bearing 33 while the lower end abuts against the limiting piece 35. A limiting ring 314 is fixedly installed above the pressing rod 34. The outer diameter of the limiting ring 314 is larger than the inner hole of the lifting block 33 to prevent the pressing rod from coming out. A slide rail 315 is vertically installed in front of the support seat 32. The slide rail 315 is slidably connected to a slider 316. The slider 316 is fixedly installed on the lifting block 33. The lifting block 33 is slidably installed in front of the support seat 32 through the cooperation of the slide rail 315 and the slider 316. In addition, the lifting power member is a cylinder or an oil cylinder or a servo electric cylinder or a cam swing arm mechanism.
