Description

Technical Field

[0001] The utility model belongs to the technical field of lithium battery production, and specifically relates to a battery core positioning device. Background Art

[0002] In the production process of lithium batteries, the positioning of the battery cell is a crucial link. It involves accurately placing the battery cell in the predetermined position to ensure that the subsequent process steps can proceed smoothly. The accuracy of the battery cell positioning directly affects the performance and safety of the lithium battery.

[0003] At present, the existing battery cell positioning devices mostly use spring clamps to achieve the positioning and limiting of the battery cells. A complete production line (i.e., flow pulling) often has multiple workstations, and correspondingly, multiple tooling fixtures are also required to ensure the precise positioning of the battery cells in each link. In order to ensure that these fixtures can achieve a high degree of consistency in the positioning of the battery cells, it is currently mainly dependent on manual positioning, adjustment and installation of each fixture. Since the fixture itself has many parts, the installation and debugging process is not only time-consuming and labor-intensive, but it is also difficult to ensure that the positioning accuracy of each fixture can reach the ideal state. This inconsistency may cause the battery cells to shift in position during the subsequent production process, which in turn affects the performance and quality of the lithium battery.

[0027] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. The described embodiment is a contact part embodiment of the utility model, not all embodiments.

[0028] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention.

[0029] Example 1

[0030] Please refer to the attached Figure 1-2, this embodiment provides a battery cell positioning device, including a battery cell positioning jig 1 and a positioning module 2. The battery cell positioning jig 1 is used to place and position the battery cell. The battery cell positioning jig 1 is block-shaped, which can be assembled by means of a flow puller, a connecting seat, etc. The positioning module 2 is used to position the battery cell on the battery cell positioning jig 1. A placement plate 101 for placing the battery cell is provided on one side of the battery cell positioning jig 1. It can be understood that a plurality of placement plates 101 can be provided, and a plurality of battery cells can be placed on one battery cell positioning jig 1. The positioning module 2 is provided on one side of the battery cell positioning jig 1, and the portion of the positioning module 2 responsible for positioning is opposite to the placement plate 101 on the battery cell positioning jig 1.

[0031] Specifically, the positioning module 2 includes a fixing frame 201, and a first driving member 202 and a second driving member 204 are arranged on the side of the fixing frame 201 facing the placement plate 101. The heights of the first driving member 202 and the second driving member 204 on the fixing frame 201 are set according to actual conditions. For the convenience of explanation, the direction from left to right of the battery cell on the placement plate 101 is the first direction, and the direction from front to back of the battery cell on the placement plate 101 is the second direction. The first driving member 202 is transmission-connected with a first positioning member 203, and the first driving member 202 can drive the battery cell on the placement plate 101 to move along the first direction through the first positioning member 203.

[0032] The first driving member 202 may be a cylinder, a gear rack, a screw guide rail, a chain, etc., and this application does not make any specific restrictions, as long as it can drive the positioning member to move. Taking a cylinder as an example, the output end of the cylinder is connected to a first positioning member 203, and the first positioning member 203 is driven to move by the extension and contraction of the cylinder, so as to drive the battery cell to move from left to right on the placement plate 101, and place the battery cell in a suitable position.

[0033] The second driving member 204 is connected to the second positioning member 205 by transmission. The second driving member 204 can drive the battery cell on the placement plate 101 to move along the second direction through the second positioning member 205. The second driving member 204 can be a cylinder, a gear rack, a screw guide rail, a chain, etc., which is not specifically limited in this application, and only needs to drive the positioning member to move. The second driving member 204 takes the screw guide rail as an example. The guide rail is arranged along the second direction. The second positioning member 205 is arranged on the moving block in the screw guide rail. Through the rotation of the screw rod, the moving block is driven to move along the direction of the guide rail, and then the second positioning member 205 drives the battery cell to move from the front to the back, and the battery cell is moved to a suitable position in the front and back direction to complete the positioning. The design method of the screw guide rail makes the adjustment method more precise. It can be understood that the second driving member 204 is a cylinder, and the output end of the cylinder is connected to the second positioning member 205. The battery cell is positioned by the telescopic movement of the cylinder. This setting is more convenient and quick. The first direction and the second direction are perpendicular.

[0034] During use, an external mobile device places the battery cell on the placement plate 101. At this time, the positioning module 2 positions the battery cell in the front, back, left and right directions. The battery cell is positioned in the left and right directions by the first driving member 202, and is positioned in the front and back directions by the second driving member 204.

[0035] By setting the positioning module 2 to perform secondary positioning on the battery cell, the consistency of the positioning position of each battery cell can be enhanced. The battery cell can be placed more accurately at the predetermined position on the production line, thereby ensuring the smooth progress of subsequent production steps. Compared with the traditional self-positioning tooling method, the newly designed positioning module 2 greatly reduces the number of parts required on the tooling fixture, which not only simplifies the structure of the fixture, but also reduces the complexity of manufacturing and installation. By reducing the number of parts, the production cost can be reduced, and the time and energy investment in manual installation can be reduced, thereby reducing the cost of manual installation. At the same time, the introduction of the positioning module 2 also improves the overall consistency of the product. Due to the high precision and stability of the positioning module 2, the positioning error of the battery cell is effectively controlled, which further reduces the product defective rate caused by the tooling positioning error.

[0036] Example 2

[0037] The difference between Example 2 and Example 1 is that this example further optimizes the cell positioning device. Figure 3 As shown, further, the battery cell positioning fixture 1 also includes a pressing plate 102. The pressing plate 102 and the placement plate 101 are arranged on the same surface. The pressing plate 102 is transmission-connected with a rotating drive member 103. The rotating drive member 103 drives the pressing plate 102 to swing to limit the battery cell on the placement plate 101. Among them, the pressing plate 102 is used to fix the battery cell after the placement plate 101 is adjusted to prevent it from shifting during the subsequent flow process. The rotating drive member 103 can be a driving device such as a motor or a rotating cylinder. When the battery cell is placed on the placement plate 101 for positioning, the pressing plate 102 is on both sides of the positioning plate. After the positioning module 2 positions the battery cell, the pressing plate 102 rotates under the drive of the rotating drive member 103 to limit the battery cell.

[0038] Preferably, at least two pressing plates 102 are provided, and at least two pressing plates 102 are respectively provided on both sides of the placement plate 101 to limit the two sides of the battery cell in the placement plate 101. By providing multiple pressing plates 102, the two sides of the battery cell can be limited to make it less likely to move. Among them, one rotating drive member 103 can control one pressing plate 102, or one rotating drive member 103 can control multiple pressing plates 102, which is not specifically limited in this embodiment.

[0039] In some embodiments, the rotary drive member 103 is a rotary follower, and an air pipe interface 103a is provided on the rotary follower. The rotary follower has high flexibility and reliability, and the rotary follower can be arranged on the lower side of the placement plate 101, and the air pipe interface 103a is arranged on the outer side of the battery cell positioning fixture 1, so as to facilitate the subsequent air path connection.

[0040] Preferably, a third driving member 3 is also provided on the fixed frame 201, and an air outlet 301 is connected to the output end of the third driving member 3. The third driving member 3 can drive the air outlet 301 to move in the direction of the trachea interface 103a, so that the air outlet 301 is connected to the trachea interface 103a. It is understandable that the third driving member 3 can be a cylinder, a screw guide rail, a gear rack, etc. Taking the cylinder as an example, the cylinder is arranged on the fixed frame 201, and the driving end thereof is connected to the air outlet 301. When the cylinder is extended, it can drive the air outlet 301 to dock with the trachea interface 103a on the battery cell positioning fixture 1, so that the rotary follower can rotate, and then drive the pressure plate 102 to rotate, position the battery cell or release the battery cell, increase the degree of automation of the equipment, and also avoid accidental contact of the rotary driving member 103, thereby improving the stability of the equipment.

[0041] In some embodiments, a limit block 101a for limiting the position of the battery cell in the first direction or the second direction is placed on one side of the placement plate 101. The limit block 101a can limit the battery cell to improve the positioning efficiency, and it can be set on the front, back, left, and right sides of the placement plate 101. The specific design position depends on the actual situation and is not limited in this embodiment.

[0042] Example 3

[0043] The difference between Example 3 and Example 1 is that this example further optimizes the cell positioning device. Figure 1 As shown, further, a fourth driving member 4 is included, and the driving end of the fourth driving member 4 is connected to the first driving member 202 and / or the second driving member 204 to drive the first driving member 202 and / or the second driving member 204 to move along the height direction of the battery cell positioning fixture 1. The fourth driving member 4 can be a cylinder, a screw guide rail, a gear rack, etc., which can drive the first driving member 202 or the second driving member 204 to move along the height direction of the battery cell positioning fixture 1, so that the battery cell positioning device can adapt to battery cell positioning fixtures 1 of different heights, thereby improving the universality of the equipment. It can be understood that it can drive the first driving member 202 and the second driving member 204 to move in the height direction at the same time; it can also drive the first driving member 202 or the second driving member 204 to move in the height direction alone, and the specific setting method is not limited.

[0044] Example 4

[0045] The difference between Example 4 and Example 1 is that this example further optimizes the positioning member in the battery cell positioning device. Figure 1-2 As shown, further, the first positioning member 203 is a first positioning plate, which is respectively arranged on both sides of the first driving member 202, and the first driving member 202 drives the first positioning plates to move closer to or farther from each other. The first driving member 202 can drive at least two first positioning plates to move closer to or farther from each other, thereby improving the efficiency of positioning, which can be positioned in the left-right direction or in the front-back direction.

[0046] In some embodiments, a positioning block 203a is disposed on one end of the first positioning plate facing away from the first driving member 202. The positioning block 203a is in a rectangular parallelepiped shape, so that the first positioning plate can be in a fixture shape, thereby improving the efficiency of positioning.

[0047] In some embodiments, an adjustment member 203b is provided on one side of the first positioning plate, and the adjustment member 203b is adjusted to make the first positioning plate closer to or farther away from the first driving member 202. The adjustment member 203b may be a bolt, and the distance between the first positioning plate and the first driving member 202 is adjusted by rotating the bolt, thereby expanding the spacing between at least two first positioning plates, so that the first positioning plates can accommodate cells of different widths or lengths.

[0048] In the present invention, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "fix" and the like 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 a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0050] In addition, the terms "horizontal", "vertical", "overhanging" and the like do not mean that the components are required to be absolutely horizontal or overhanging, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0051] In the present utility model, unless otherwise clearly specified and limited, the first feature being above or below the second feature may include the first and second features being in direct contact, or may include the first and second features not being in direct contact but being in contact through another feature between them. Moreover, the first feature being above, above, and above the second feature includes the first feature being directly above and obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. The first feature being below, below, and below the second feature includes the first feature being directly below and obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.
