Description

Technical Field

[0001] The utility model relates to the field of battery production, in particular to a wiping material receiving base module. Background Art

[0002] In the production process of square shell batteries, after injecting liquid into the batteries by an injector, it is necessary to wipe off the excess electrolyte at the injection port with a wiping paper tape. At present, the paper tape receiving base of the existing square shell battery injector does not fix the paper tape, but only serves as a simple support for the paper tape. After the wiping paper tape is cut by a cutting scissors, the paper tape of an appropriate length falls onto the receiving base, and then the mechanical gripper grabs the paper tape and moves it to the injection port of the battery cell for wiping. However, in the process of the mechanical gripper grabbing the paper tape on the receiving base, the paper tape is likely to fall off and the mechanical hand fails to grab the paper tape, which greatly increases the process time and results in low efficiency.

[0029] The following will clearly and completely describe the concept, specific structure and technical effects generated by the present utility model in combination with the embodiments and the drawings, so as to fully understand the purpose, features and effects of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, other embodiments obtained by those skilled in the art without creative efforts shall fall within the scope of protection of the present utility model. In addition, all the connection / connection relationships involved in the patent do not simply refer to the direct connection of components, but refer to the more optimal connection structure that can be formed by adding or reducing connection accessories according to the specific implementation situation. Each technical feature in the creation of the present utility model can be combined interactively on the premise of not conflicting with each other. Refer to Figures 1-9 .

[0030] Specifically refer to Figure 1 , Figure 2 , Figure 3 , the present utility model provides:

[0031] A wiping material receiving base module, comprising a guide rail mounting plate 1, a guide rail device 11 and a driving device are arranged on the guide rail mounting plate 1, a material receiving base main body 2 is arranged on the guide rail device 11, an output end of the driving device is connected to the material receiving base main body 2 and is used for driving the material receiving base main body 2 to move along a guiding direction of the guide rail device 11, a middle mounting hole 20 is formed in a middle position of the material receiving base main body 2, a compression spring 91 and a push rod 92 are arranged in the middle mounting hole 20, one end of the push rod 92 extends outside the middle mounting hole 20, a first clamping jaw 31 and a second clamping jaw 32 are respectively hinged to two sides of the material receiving base main body 2, a first connecting rod is hinged to one end of the first clamping jaw 31 far away from its clamping part, a second connecting rod is hinged to one end of the second clamping jaw 32 far away from its clamping part, a free end of the first connecting rod and a free end of the second connecting rod are hinged through a sliding pin, a sliding pin guiding groove for guiding the sliding pin is arranged on the material receiving base main body 2, a pull rod 6 is arranged on a side part of the material receiving base main body 2, a tension spring 7 is arranged between the pull rod 6 and the sliding pin, and a cam 33 is arranged at one end of the first clamping jaw 31 and / or the second clamping jaw 32 far away from its clamping part.

[0032] When the present utility model is specifically applied, in the initial state, the first jaw 31 and the second jaw 32 are kept in a clamped state under the pulling force of the tension spring 7. After starting to work, first, the entire wiping and material receiving base module reaches the material receiving station, and the driving device drives the entire material receiving base body 2 together with other components mounted on the material receiving base body 2 to rise along the guiding direction of the guide rail device 11. When the rising reaches the preset height, the cam 33 will touch a preset stopper on the device. Under the action of the stopper, the first jaw 31 and the second jaw 32 will overcome the pulling force of the tension spring 7 and open. At this time, the cut paper tape is placed at the position between the first jaw 31 and the second jaw 32. After the paper tape is in place, the driving device drives the material receiving base body 2 to descend. During the descending process, the cam 33 separates from the stopper, and the first jaw 31 and the second jaw 32 contract under the pulling force of the tension spring 7 and clamp the paper tape to prevent the paper tape from falling during subsequent movement. Further, the wiping and material receiving base module carries the paper tape to the wiping station. At this time, the driving device drives the material receiving base body 2 to rise. When the rising reaches the preset height, the cam 33 will touch a preset stopper on the device. Under the action of the stopper, the first jaw 31 and the second jaw 32 will overcome the pulling force of the tension spring 7 and open. At this time, the manipulator for gripping the paper tape will descend to grip the paper tape. During the descending process of the manipulator, the corresponding part of the manipulator will press against the ejector rod 92, so that the ejector rod 92 compresses the compression spring 91 downward. When the compression spring 91 is compressed, the ejector rod 92 is completely pushed into the middle mounting hole 20. At this time, the middle part of the paper tape is pressed downward, and the periphery of the paper tape warps up. In this case, it is convenient for the manipulator to grip the paper tape, and the paper tape can be easily gripped by the manipulator, avoiding the situation that the manipulator cannot grip the paper tape, effectively saving time and improving production efficiency.

[0033] In this embodiment, the cam 33 is arranged at one end of the first jaw 31 far from its clamping part. The first jaw 31 has an extended mounting part at one end far from its clamping part, and the cam 33 is arranged at the extended mounting part.
