Description

Technical Field

[0001] The utility model relates to the field of hot pressing mechanisms for electric cores, in particular to a fixing mechanism for a hot pressing trace-eliminating film. Background Art

[0002] At present, more and more battery cell processes require hot pressing processes, and the padding press plate is the current mainstream structure. The padding press plate is composed of multiple plates, and there is a certain gap between the plates. When the battery cell is directly placed in the padding press plate, the gap between the plates is likely to cause indentations on the surface of the battery cell. In order to solve the indentation problem, a piece of anti-marking film is placed between the battery cell and the padding press plate. Therefore, the anti-marking film has become a consumable used in the battery cell hot pressing process.

[0003] In the existing hot pressing mechanism, a tensioning mechanism needs to be provided at both ends of the first mark-eliminating film, which makes the first mark-eliminating film in a tensioned state for a long time, causing the first mark-eliminating film to wear quickly and have a short life. In addition, to replace the first mark-eliminating film, the two ends of the first mark-eliminating film need to be removed from the tensioning mechanism, and the removal and replacement steps are time-consuming. Therefore, extending the service life of the mark-eliminating film, extending the replacement time of the mark-eliminating film, simplifying the replacement process of the mark-eliminating film, and shortening the replacement time of the mark-eliminating film can improve the production efficiency of the battery cell.

[0029] The following will clearly and completely describe the concept, specific structure and technical effects of the utility model in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the utility model. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the formation of a better connection structure by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the creation of the utility model can be combined interchangeably without conflicting with each other.

[0030] Reference Figure 1-Figure 3 A fixing mechanism for a hot-pressed mark-eliminating film comprises: a material seat 1; a material placement position 2, which is arranged on the material seat 1 and is used for placing a mark-eliminating film 3 and a battery cell 4; a lifting group 5, which is arranged in the material seat 1 and can be used to lift the mark-eliminating film 3 and the battery cell 4 placed on the material seat 1; a guide rod 6, which is arranged above the material seat 1 and can be used to guide the mark-eliminating film 3 to move on the material seat 1.

[0031] In the prior art, since the mark-eliminating film has a certain flexibility, when setting the fixing mechanism of the hot-pressed mark-eliminating film, in order to form a first grasping space between the first mark-eliminating film and the first battery cell when the first lifting group lifts the first battery cell, so that the first material-cutting gripper can grasp the first battery cell; therefore, a tensioning mechanism is set to constrain the free ends of both sides of the first mark-eliminating film. It is a subjective belief of those skilled in the art that a tensioning mechanism must be set to form the first grasping space, which has a certain technical bias;

[0032] However, although the trace-eliminating film is flexible, it also has elasticity and a certain degree of rigidity. Therefore, the setting of the tensioning mechanism is cancelled, and the hot pressing effect of the first battery cell will not be affected at all. When the lifting group 5 lifts the battery cell 4, a grabbing space A can be formed between the battery cell 4 and the trace-eliminating film 3 for the material grabbing clamp to grab. Instead, the tensioning mechanism for tensioning the trace-eliminating film is cancelled, so that the trace-eliminating film can be prevented from being in a taut state for a long time, thereby extending the service life of the trace-eliminating film. When the lifting group descends, the trace-eliminating film is flattened by the ductility of the film itself. And the tensioning mechanism for tensioning the trace-eliminating film is cancelled, and the two ends of the trace-eliminating film are in an unconstrained state. When the trace-eliminating film needs to be replaced, it only needs to be pulled out from between the material seat and the guide rod. The replacement of the trace-eliminating film is simple and the replacement time is short.

[0033] Furthermore, the guide rod 6 includes a left guide rod 61 arranged on the left side of the material placement position 2 and a right guide rod 62 arranged on the right side of the material placement position 2. The minimum distance from the left guide rod 61 to the right guide rod 62 is less than the width / length of the battery cell 4 to ensure that there is enough distance between the guide rods 6 for hot pressing of the battery cell 4.

[0034] Specifically, the lifting group 5 includes a lifting block 51 and a driving member 52;

[0035] The output end of the driving member 52 is arranged toward the material placement position 2;

[0036] The lifting block 51 is arranged on the output end of the driving member 52;

[0037] The length of the lifting block 51 is the same as that of the material holder 1 , and the battery cell 4 can be lifted stably.

[0038] More specifically, when the driving member 52 retracts, the upper surface of the top material block 51 and the upper surface of the material seat 1 are arranged at the same horizontal plane, so as to avoid indentations on the surface of the battery cell 4 due to the unevenness of the upper surface of the top material block 51 and the upper surface of the material seat 1 when the battery cell 4 is hot pressed.

[0039] More specifically, a mark-eliminating film fixing part 511 is provided on the lifting block 51 to prevent the mark-eliminating film 3 from being displaced when the driving part 52 is extended and retracted, thereby preventing indentations from appearing on the surface of the battery cell 4 when the battery cell 4 is hot-pressed.

[0040] More specifically, the trace-eliminating film fixing piece 511 is arranged along the length direction of the lifting block 51 , and is used to fix the trace-eliminating film 3 on the material placement position 2 .

[0041] More specifically, the ejecting block 51 is disposed in the middle of the material seat 1 , and the distance from the ejecting block 51 to the left guide rod 61 is the same as the distance from the ejecting block 51 to the right guide rod 62 .

[0042] Specifically, the width of the lifting block 51 is smaller than the width / length of the battery cell 4 , so when the battery cell 4 is lifted up, a grasping space A for the unloading grasping clamp to grasp the battery cell 4 can be formed.

[0043] Furthermore, guide rod fixing groups for fixing the leading and trailing ends of the guide rod 6 are provided on both sides of the material seat 1 .

[0044] Specifically, the guide rod 6 is rotatably arranged on the guide rod fixing group; more specifically, the head and tail ends of the guide rod 6 can be connected to the guide rod fixing group through bearings. At this time, the guide rod 6 also has the function of pulling the material.

[0045] The above is a specific description of the preferred implementation of the utility model, but the invention of the utility model is not limited to the described embodiments. Technical personnel familiar with the field can also make various equivalent deformations or substitutions without violating the spirit of the utility model. These equivalent deformations or substitutions are all included in the scope defined by the claims of this application.
