Description

Technical Field

[0001] This utility model belongs to the field of storage battery manufacturing technology, and in particular relates to a device for unscrewing the rubber cap of a storage battery. Background Technology

[0002] The battery cover has an adhesive reservoir inside, and the corresponding battery compartment has a protruding edge; the top surface of the battery cover also has a sealing cap for dispensing adhesive; after the battery compartment cover sealing process is completed, the sealing cap on the assembled battery cover needs to be removed before the battery terminals can be placed in that position and the subsequent installation process can be completed.

[0003] For example, Chinese invention CN117457999A discloses an automatic screw-off frame for sealing caps used in battery cover potting. The rotating screw-off assembly includes a reciprocating telescopic cylinder, a rack, and a rotating gear. The rotating gear is rotatably connected to a lifting platform. The telescopic end of the reciprocating telescopic cylinder is fixedly connected to the rack. The rotating gear meshes with the rack for transmission. A cap sleeve is connected to the bottom of the rotating gear. The rotating screw-off assembly controls the cap sleeve to rotate and screws it off.

[0004] However, the existing two rotating cap screwing assemblies are driven by a rack and pinion, which makes it very inconvenient to adjust the distance between the two rotating cap screwing assemblies in actual use. This makes it difficult to flexibly adapt to different models of batteries, resulting in poor universality and flexibility of the battery cap screwing device. Utility Model Content

[0005] The purpose of this invention is to provide a battery cap screwing device that uses a lead screw to drive two cap screwing components to move synchronously, thereby adjusting their spacing. This solves the problem that existing cap screwing devices cannot flexibly adapt to different battery models, resulting in poor versatility and flexibility of use.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a battery cap screwing device, comprising a screwing mechanism, which includes a lifting platform slidably connected to two screwing assemblies and a lead screw rotatably connected to it. Each screwing assembly includes a sliding seat, which is fixedly connected to a nut that engages with the lead screw, used to synchronously drive the two screwing assemblies to move towards or away from each other via the rotation of the lead screw, thereby adjusting the spacing. The sliding seat is rotatably connected to a rotating shaft and fixedly connected to a telescopic cylinder. The rotating shaft is fixedly connected to a driven gear, and a sleeve adapted to the cap is fixedly connected to the lower end of the rotating shaft. The telescopic cylinder has a rack fixedly connected to its telescopic end, meshing with the driven gear. The telescopic cylinder's telescopic movement drives the rotating shaft to rotate via the rack.

[0008] As a preferred embodiment of this utility model, the sliding seat is rotatably connected to a roller corresponding to the position of the driven gear, and the roller abuts against the back side of the rack to ensure the stability of the meshing between the rack and the driven gear.

[0009] As a preferred embodiment of this utility model, the roller is an H-shaped grooved roller, and the groove width of the H-shaped grooved roller is adapted to the width of the rack.

[0010] As a preferred embodiment of this utility model, the rotating shaft has a through hole penetrating the sleeve, the sliding seat is fixedly connected to a cylinder, and the telescopic end of the cylinder is fixedly connected to a push rod that is clearance-fitted with the through hole, which is used to push out the rubber cap stuck in the sleeve.

[0011] As a preferred embodiment of this utility model, both ends of the lead screw are connected to rotating handles.

[0012] This utility model has the following beneficial effects:

[0013] This utility model has two screw cap assemblies slidably connected to a lifting platform. The screw rotation synchronously drives the two screw cap assemblies to move towards or away from each other, thereby flexibly adjusting the distance between the two sleeves according to the model and size of the battery. This allows for the screwing off of battery caps of different models or sizes, effectively improving the overall versatility and flexibility of use.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0025] Please see Figure 1 and 2 As shown, this utility model is a battery cap screwing device, which includes the same frame, automatic conveying roller and positioning component as the prior art. The frame, automatic conveying roller and positioning component are not shown. The difference is in the screwing mechanism.

[0026] like Figure 3 and 4 As shown, the cap-tightening mechanism includes a lifting platform 1, which is slidably connected to the frame and moves vertically via a cylinder on the frame. The lifting platform 1 is slidably connected to two cap-tightening assemblies 2 via a guide rail slider assembly, and to a lead screw 101 rotatably connected via a bearing seat. The lead screw 101 has threads extending from the middle to both ends in opposite directions, and both ends of the lead screw 101 are connected to a rotating handle 102 for easy rotation.

[0027] The screw cap assembly 2 includes a sliding seat 201, which is slidably connected to the guide rail on the side of the lifting platform 1 via a slider. The sliding seat 201 is fixedly connected to a nut 202 that cooperates with the lead screw 101, which is used to synchronously drive the two screw cap assemblies 2 to move towards each other or away from each other by rotating the lead screw 101, thereby adjusting the spacing.

[0028] The sliding seat 201 has a connecting plate fixedly connected to the side, which is arranged vertically. The two connecting plates are rotatably connected by a vertically arranged rotating shaft 3 through a bearing seat. The sliding seat 201 also has a telescopic cylinder 4 fixedly connected to the side. The rotating shaft 3 is fixedly connected to a driven gear 301. The lower end of the rotating shaft 3 is fixedly connected to a sleeve 302 that matches the rubber cap.

[0029] The telescopic cylinder 4 has a rack 401 fixedly connected to its telescopic end, which meshes with the driven gear 301. The telescopic cylinder 4 moves the rack 401 through its telescopic movement. The rack 401 meshes with the driven gear 301 to drive the rotating shaft 3 to rotate, and then the sleeve 302 rotates to unscrew the cap on the battery cover.

[0030] In a preferred embodiment, the sliding seat 201 is rotatably connected to a roller 203 corresponding to the position of the driven gear 301, and the roller 203 abuts against the back side of the rack 401 to ensure the stability of the meshing between the rack 401 and the driven gear 301. Furthermore, the roller 203 is an H-shaped grooved wheel, and the groove width of the H-shaped grooved wheel is adapted to the width of the rack 401, thereby providing support and limiting for the rack 401, thus restricting the position of the rack 401 in both the horizontal and vertical directions, effectively improving the stability of the rack 401 during movement.

[0031] At the same time, such as Figure 5 As shown, the rotating shaft 3 has a through hole that passes through the sleeve 302, making the rotating shaft 3 a tubular structure as a whole. The sliding seat 201 is fixedly connected to the cylinder 5 by the mounting bracket. The telescopic end of the cylinder 5 is fixedly connected to the push rod 501 that is clearance-fitted with the through hole.

[0032] The cylinder 5 drives the push rod 501 to move downward, so that the push rod 501 extends into the sleeve 302. The push rod 501 pushes out the rubber cap stuck in the sleeve 302, avoiding the rubber cap remaining in the sleeve 302 and affecting the next rubber cap unscrewing operation, thus ensuring the overall reliability of use.
