[0040] Referring to Figures 1 to 3 The formation clamp of the first aspect embodiment of the present application comprises a pushing component 100, a layer plate component 300, a first transmission assembly 400 and a second transmission assembly 500.
[0041] The layer plate component 300 is arranged in multiple, each layer plate component 300 is arranged in the first direction, and the pushing component 100 can move each layer plate component 300 in the first direction to press and clamp the battery cell; the first transmission assembly 400 is arranged on each layer plate component 300, and the layer plate component 300 can drive the first transmission assembly 400 to move synchronously when it moves in the first direction; the second transmission assembly 500 is movably arranged on each layer plate component 300, and the first transmission assembly 400 can act on the adjacent second transmission assembly 500 downstream in the first direction when it moves; the second transmission assembly 500 is provided with a probe assembly 600, and the second transmission assembly 500 drives the probe assembly 600 to move close to the battery cell.
[0042] It can be understood that the layer plate components 300 are arranged in the first direction, and there is a space between adjacent layer plate components 300 for placing the battery cell. The pushing component 100 acts on one end of the queue of layer plate components 300, and when the pushing component 100 moves towards the layer plate components 300, the layer plate components 300 are sequentially stressed and gradually move in the first direction and sequentially move towards each other, so that the adjacent layer plate components 300 can press and clamp the battery cell. After the pushing component 100 is moved to the position, the battery cell can be formed under the clamping action of high pressure. The driving power source for driving the pushing component 100 to move is the driving force, and through the setting of the first transmission assembly 400 and the second transmission assembly 500, the first transmission assembly 400 follows the layer plate components 300, and the first transmission assembly 400 drives the second transmission assembly 500 on the downstream adjacent layer plate components 300, and the probe assembly 600 is arranged on the second transmission assembly 500 to follow, so that the probe assembly 600 can move close to the battery cell and the conductive sheet. In the process of moving the adjacent layer plate components 300 to clamp the battery cell, the first transmission assembly 400 and the second transmission assembly 500 are also synchronized, so that the probe assembly 600 can contact the conductive sheet after the adjacent layer plate components 300 are moved to the position, so that the battery cell can be powered on, thereby realizing the effect of the two actions of clamping the battery cell and the probe assembly 600 moving close to the battery cell through linkage by one driving power source.
[0043] In some embodiments, the formation clamp further comprises a rack and a guide component arranged in the first direction, and the pushing component 100, the layer plate component 300 and the guide component are arranged on the rack. In order to limit the movement direction of the pushing component 100 and the layer plate component 300, a guide component such as a guide rod, a guide groove or the like can be arranged on the rack to guide the movement of the pushing component 100 and the layer plate component 300, thereby ensuring the movement accuracy.
[0044] Referring to Figures 1 to 3 The formation clamp of the first aspect embodiment of the present application simplifies the overall structure of the clamp by arranging the first transmission assembly 400 and the second transmission assembly 500 on each layer plate component 300, and driving the second transmission assembly 500 of the downstream adjacent layer plate component 300 to move, so that the probe assembly 600 arranged on the second transmission assembly 500 can move close to the battery cell to power on the battery cell.
[0045] It should be noted that the first transmission assembly 400 is fixedly arranged on the layer plate component 300, and the second transmission assembly 500 is movably arranged on the layer plate component 300, so the specific structural design of the second transmission assembly 500 can have multiple ways to meet the linkage setting mode. In some embodiments of the present application, referring to Figure 2The second transmission assembly 500 comprises a support 510 and a movable element 520, the movable element 520 and the probe assembly 600 are arranged on the support 510, and the movable element 520 can be pushed by the first transmission assembly 400 to drive the support 510 and the probe assembly 600 to move.
[0046] It can be understood that the support 510 serves as a bearing base, the probe assembly 600 is fixedly arranged on the support 510, and the movable element 520 is fixedly connected with the support 510 to be synchronously movable, the movable element 520 is movably arranged on the layer plate component 300 and is movable under the driving of the first transmission assembly 400, so that the probe assembly 600 moves close to the battery cell and the conductive sheet, and the battery cell is powered after the probe assembly 600 contacts the conductive sheet.
[0047] In some embodiments, the movable element 520 can be movable in a rolling or sliding manner, when the movable element 520 is a sliding element, the sliding element is slidably arranged on the layer plate component 300 and slides on the layer plate component 300 under the driving of the first transmission assembly 400 to move the probe assembly 600 close to the battery cell, and the corresponding technical effects can also be achieved.
[0048] In order to make the movable element 520 move more smoothly and reduce the friction force during movement, in some embodiments of the present application, referring to Figure 2 The first transmission assembly 400 comprises a roller transmission element, and the movable element 520 comprises a roller body, the roller transmission element can push the roller body to move when the roller transmission element moves, and the roller body rolls to drive the support 510 and the probe assembly 600 to move.
[0049] It can be understood that, by setting the movable element 520 to move in a rolling manner, the roller body rolls and moves relative to the layer plate component 300 under the driving of the roller transmission element, so that the probe assembly 600 moves close to the battery cell.
[0050] In some embodiments, when the movable element 520 comprises a roller body, the support 510 is a roller support 510, the roller body is rotatably arranged on the roller support 510, and the probe assembly 600 is arranged on the roller support 510, the roller body moves under the pushing of the roller transmission element, so as to drive the probe assembly 600 to move.
[0051] In some embodiments of the present application, referring to Figure 2, the rolling surface 410 is formed on the roller transmission member for pushing the roller body to roll, and the roller body is driven and moves along the rolling surface 410. It can be understood that the rolling surface 410 formed on the roller transmission member is used to guide and act on the roller body, so that the rolling surface 410 can act on and push the roller body when the layer plate component 300 moves, and the roller body of the adjacent layer plate component 300 moves along the rolling surface 410 of the roller transmission member, and the probe assembly 600 moves close to the battery and the conductive sheet.
[0052] In some embodiments, the rolling surface 410 is a plane, a curved surface or an arc surface, and the like, which is adaptively adjusted under the premise of being able to smoothly push the roller body.
[0053] In order to better push the roller body and make the roller body roll smoothly on the rolling surface 410, in some embodiments of the present application, with reference to Figure 2 , the rolling surface 410 is arranged at a preset angle with the first direction. It can be understood that by arranging the rolling surface 410 at an angle with the pushing direction of the pushing component 100, the roller transmission member can more smoothly push the rollers of the adjacent layer plate during the movement of the pushing component 100, and the rollers of the adjacent layer plate component 300 move along the rolling surface 410 of the roller transmission member.
[0054] In some embodiments, the roller transmission member can be a plate member or a strip-shaped structural member, etc., which is bent to form an outer end and an inner end. The inner end is arranged on the layer plate component 300, the outer end is formed with the rolling surface 410, and a bent portion for transition is arranged between the inner end and the outer end, so that the roller transmission member can push the roller body to move without affecting the clamping of the battery by the adjacent layer plate component 300.
[0055] After the end of the battery formation process, in order to reduce the adjustment time of the formation clamp, in some embodiments of the present application, with reference to Figure 2 , the layer plate component 300 is provided with an elastic member 700, which is used to provide an elastic force acting on the support 510, so that the support 510 can be reset.
[0056] It can be understood that when the pushing component 100 pushes each layer plate component 300, the support 510 and the probe assembly 600 will move towards the battery and the conductive sheet. After the pushing force of the pushing component 100 acting on the layer plate component 300 disappears, the support 510 will move away from the battery and be reset by the arrangement of the elastic member 700. By adjusting the elastic force provided by the elastic member, the support 510 will be reset to a suitable preset position such as the initial position, thereby reducing the adjustment time of the formation clamp, and the probe assembly 600 can be used for the next formation process, improving the production efficiency.
[0057] In some embodiments, the elastic member 700 can be a spring, which provides appropriate elastic force by acting on the support 510 through one or more springs. Specifically, one end of the spring can be arranged on the layer plate member 300, and the other end can be arranged on the support 510, so that the spring can be reliably installed.
[0058] In order to ensure that the pressure is concentrated on the position of the battery cell, to apply pressure to battery cells of different specifications, and to better fix the battery cell, in some embodiments of the present application, referring to Figure 3 , the formation clamp further comprises a waistcoat assembly 800 arranged on the layer plate member 300 and used for placing the battery cell.
[0059] It can be understood that when the waistcoat assembly 800 is arranged on the layer plate member, the battery cell is located in the waistcoat assembly 800, and the clamping action of the adjacent layer plate member concentrates the pressure on the position of the battery cell through the waistcoat assembly 800, thereby ensuring the concentration of the pressure. By adaptively adjusting the structure of the waistcoat assembly 800, pressure can be applied to battery cells of different specifications.
[0060] In some embodiments, part of the battery cell is small in volume and cannot be directly placed on a large-area layer plate. Based on this, the battery cell can be fixed by the arrangement of the waistcoat assembly 800.
[0061] In some embodiments, the battery cell waistcoat assembly 800 comprises a battery cell pressing plate, a battery cell fixing assembly, and a battery cell base. The battery cell is arranged on the battery cell base, the battery cell fixing assembly fixes the battery cell, and the battery cell fixing assembly arranged on the battery cell base can be used to supply power to the battery cell. The flexible gasket is arranged on the battery cell pressing plate and protrudes from the surface of the battery cell pressing plate. In this way, the pressure can be concentrated on the position of the battery cell.
[0062] It should be noted that in order to provide high-pressure clamping action on the battery cell to enable the battery cell to be formed in a clamped state, in some embodiments of the present application, referring to Figure 1 , the formation clamp further comprises a driving member 200 for driving the pushing member 100 to move in the first direction. Based on the driving force provided by the driving member 200 as a power source, the clamp composed of the pushing member 100 and the plurality of layer plate members 300 can clamp the battery cell, so that the battery cell can be formed under the clamping action of high pressure.
[0063] In some embodiments, the driving member 200 can be integrally arranged on the formation clamp to enable the driving member 100 to be driven conveniently. In other embodiments, the driving member 200 can be arranged on the formation device, and the formation clamp can be used by means of an external power source, which can also achieve the corresponding technical effects.

It can be understood that the screw rod 220 is driven to rotate through the rotation of the driving member 210 to drive the pushing component 100 to move, so that the pushing component 100 can move in the first direction. In other embodiments, the transmission of the screw rod 220 can not be limited, such as directly driving the pushing plate to move close to the layer plate through the linear driving member 210, and only the linear motion of the pushing component 100 is required. In some embodiments, the pushing component 100 is a pressing plate. In other embodiments, the pushing component 100 can be a structure with other structural forms which is convenient for stable pressure, and can realize the function of pressing each layer plate component 300.
[0065] The formation device in the second aspect of the present application can be a device for forming an electric core, and comprises the formation clamp in the first aspect of the present application. The formation clamp can realize the two actions of pressing the electric core and the probe close to the electric core through one power source, and has the effect of simplifying the structure. Therefore, the formation device with the formation clamp has lower energy consumption, simpler structure, and is more conducive to the preparation of the electric core.

The formation device has the formation clamp in the first aspect of the present application, and thus can also make the structure of the production line more simple.
[0067] It can be understood that the formation device in the second aspect of the present application and the production line in the third aspect of the present application both have the technical effects of the formation clamp in the first aspect of the present application, and thus will not be described again.
[0068] The technical features of the above-described embodiments can be combined arbitrarily. In order to make the description simple, all possible combinations of the technical features in the above-described embodiments are not described, but as long as the combinations of the technical features do not exist contradictory, they should be considered as the scope of the present application.
