Technical Field

[0001] The utility model relates to the technical field of battery cup liquid filling machines, in particular to a double stroke disengagement auxiliary mechanism. Background Art

[0002] A battery cup filling machine is a device used in the battery production process to inject electrolyte into the battery casing (cup). This type of equipment is very important in the battery manufacturing industry, especially for the production of grooved cylindrical batteries and similar models.

[0003] In a grooved cylindrical battery cup filling machine, when the upper cup is separated from the lower tray, the seal on the cup can lift some batteries. To prevent this, a mechanism is typically added to assist in battery disengagement. Conventional mechanisms use a pneumatic cylinder to directly drive a blade to assist in battery disengagement. However, this cylinder-driven disengagement mechanism takes up a lot of space, making it inconvenient to layout. Therefore, a dual-stroke disengagement assist mechanism was proposed to address this issue. Utility Model Content

[0004] In order to make up for the above shortcomings, the utility model provides a double-stroke disengagement auxiliary mechanism, which aims to improve the existing technology in which the cylinder directly drives the insert to achieve the function of assisting battery disengagement. However, the disengagement mechanism directly driven by the cylinder occupies a large space in the front and back, which is inconvenient for the layout of the mechanism.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions: a double-stroke disengagement auxiliary mechanism, comprising a workbench, the surface of the workbench is fixedly connected to two groups of symmetrically arranged long guide rails, the surface of the long guide rails is slidably connected to a movable seat, the surfaces of the two groups of movable seats are fixedly connected to a C-shaped frame, the surface of the C-shaped frame is fixedly connected to a plug, the surface of the workbench is provided with a drive assembly, the drive assembly comprises a rack 1, the rack 1 is fixedly connected to the bottom surface of the C-shaped frame, the surface of the workbench is fixedly connected to a tooth plate 2, and a gear is meshed between the rack 1 and the tooth plate 2.

[0007] The surface of the workbench is fixedly connected to a short guide rail, the surface of the short guide rail is slidably connected to a mounting seat, the surface of the mounting seat is fixedly connected to an L-shaped plate, one end of the L-shaped plate is provided with a mounting groove, and the gear is rotatably connected to the inside of the mounting groove.

[0008] As a further description of the above technical solution:

[0012] As a further description of the above technical solution:

[0013] The bottom surface of the movable seat is provided with a groove, and the shape of the groove is consistent with the shape of the long guide rail.

[0014] As a further description of the above technical solution:

[0016] The utility model has the following beneficial effects:

[0017] 1.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Reference Figure 1 - Figure 2 The utility model provides an embodiment: a double stroke disengagement auxiliary mechanism, comprising a workbench 1, wherein the bottom surface of the workbench 1 is fixedly connected with two groups of symmetrically arranged support legs 2, and a reinforcement rod 21 is fixedly connected between the two groups of support legs 2. The support legs 2 are connected together by the reinforcement rod 21, thereby enhancing the structural stability and load-bearing capacity of the workbench 1. The surface of the workbench 1 is fixedly connected with two groups of symmetrically arranged long guide rails 3, and the surface of the long guide rails 3 is slidably connected with a moving seat 4. The long guide rails 3 are guide rails for the moving seat 4 to move along the length direction of the workbench 1. The bottom surface of the moving seat 4 is provided with a groove, and the shape of the groove is consistent with the shape of the long guide rails 3. The shape of the groove matches the long guide rails 3 to ensure the stable movement of the moving seat 4 on the long guide rails 3. The surfaces of the two groups of moving seats 4 are fixedly connected with C-shaped frames 5, and the surface of the C-shaped frames 5 is fixedly connected with inserts 6. There are multiple groups of inserts 6, and the array is distributed on the surface of the C-shaped frame 5. The movement of the C-shaped frame 5 drives the multiple groups of inserts 6 to move synchronously. When the upper cup is separated from the lower tray, the inserts 6 are stuck on both sides of the battery rolling groove to prevent the battery from being lifted up by the sealing ring on the cup.

[0026] Reference Figure 1 - Figure 3 The surface of the workbench 1 is provided with a driving assembly 7, which includes a rack 1 71. The rack 1 71 is fixedly connected to the bottom surface of the C-shaped frame 5. The rack 1 71 is used to transmit the power for the movement of the C-shaped frame 5. The surface of the workbench 1 is fixedly connected to a rack 2 72. A gear 73 is engaged between the rack 1 71 and the rack 2 72. When the gear 73 rotates, the movement directions of the rack 1 71 and the rack 2 72 are opposite. The surface of the workbench 1 is fixedly connected to a short guide rail 74. The surface of the short guide rail 74 is slidably connected to a mounting seat 75. The bottom surface of the mounting seat 75 is provided with a groove, and the shape of the groove is consistent with the shape of the short guide rail 74. The short guide rail 74 is a guide rail for the mounting seat 75 to move in the vertical direction. The bottom of the mounting seat 75 is also provided with a groove to ensure the stable movement of the mounting seat 75 on the short guide rail 74.

[0027] Reference Figure 1 - Figure 3An L-shaped plate 76 is fixedly connected to the surface of the mounting base 75. A mounting slot 77 is defined at one end of the L-shaped plate 76. Gear 73 is rotatably connected to the interior of the mounting slot 77. The mounting slot 77 on the L-shaped plate 76 is used to secure gear 73, ensuring its stable rotation. A cylinder 78 is fixedly connected to the surface of the workbench 1. The output end of the cylinder 78 is fixedly connected to the other end of the L-shaped plate 76. The cylinder 78 is used to drive the L-shaped plate 76 to move. The position of the second rack 72 is fixed. Through the meshing relationship with the second rack 72, the gear 73 rotates during the movement, thereby extending the first rack 71 and achieving a stroke that doubles the cylinder 78.

[0028] Working Principle: When cylinder 78 receives a control signal, the piston inside it begins to move, pushing L-shaped plate 76 in the specified direction along short guide rail 74. Because L-shaped plate 76 is fixedly connected to gear 73, gear 73 rotates accordingly. Gear 73 meshes with rack 2 72, causing rack 1 71, driven by C-shaped frame 5, to move along long guide rail 3.

[0029] Due to the meshing relationship between rack 1 71 and rack 2 72, during the rotation of gear 73, rack 1 71 moves twice as far as the piston of cylinder 78, increasing the travel distance of C-shaped frame 5 and achieving a double stroke effect. When C-shaped frame 5 moves, the insert 6 fixed to its surface also moves synchronously, ensuring that when the upper cup and lower tray are separated, the insert 6 can be accurately locked on both sides of the battery rolling groove, preventing the battery from being lifted by the sealing ring of the cup.

[0030] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
