Description

[0002] With the rapid development of mobile phones, laptops, electric vehicles, power tools, etc., secondary batteries with high energy density, high cycle life and high safety performance have been widely used and developed. There is an urgent need for secondary batteries with larger capacity, better durability and longer battery life.

[0003] The existing secondary batteries need to be clamped and fixed in the process of processing and forming. At present, the clamping mechanism of the clamp fully utilizes the reaction force of the elastic element in the clamp to clamp and fix the secondary battery after the external cylinder top is extended at the upper and lower material positions; however, during the handling process of the clamp, due to vibration, gravity and other reasons, it is very easy to cause the position of the bearing top on the bearing guide plate to deviate, causing the clamp to loosen. After the clamp is loosened, the positioning of the battery cell in the clamp will be displaced, and the position of the battery cell injection port and the battery cell injection nozzle will be misaligned, causing injection spray, affecting the processing and forming efficiency of the secondary battery. Therefore, how to improve the clamping stability of the clamp is an urgent problem to be solved. Utility Model Content

[0049] In the embodiments of this application, please refer to Figures 1 to 8 The present application provides a layer clamp 100 , which includes: a fixing seat 110 , a clamping unit 120 , a driving unit 130 and a locking unit 140 .

[0050] Specifically, the clamping unit 120 is disposed on the fixing seat 110 , and includes a first clamping member 121 and a second clamping member 122 , and a receiving cavity 123 between the first clamping member 121 and the second clamping member 122 , wherein the receiving cavity 123 is used to receive the single battery 200 . The above-mentioned driving unit 130 includes: a driving member 131 and a transmission unit 132, the driving member 131 is movably connected to the transmission unit 132, and the transmission unit 132 is transmission-connected to the first clamping member 121 and / or the second clamping member 122, that is, the transmission unit 132 can be transmission-connected to the first clamping member 121 to control the first clamping member 121 to approach or move away from the second clamping member 122; the transmission unit 132 can also be transmission-connected to the second clamping member 122 to control the second clamping member 122 to approach or move away from the first clamping member 121; the transmission unit 132 can also be transmission-connected to the first clamping member 121 and the second clamping member 122 respectively to control the first clamping member 121 and the second clamping member 122 to approach or move away from each other.

[0051] In the present application, the driving member 131 moves relative to the transmission unit 132, so that the transmission unit 132 drives the first clamping member 121 and the second clamping member 122 to move closer or farther. The locking unit 140 is selectively connected to the driving member 131, and the locking unit 140 is used to fix the relative position relationship between the driving member 131 and the transmission unit 132.

[0052] It can be understood that the driving member 131 in the present application uses the transmission unit 132 to control the first clamping member 121 and the second clamping member 122 to move away from each other, so that the space of the receiving cavity 123 between the first clamping member 121 and the second clamping member 122 is increased, which is convenient for putting in or taking out the single battery 200; the driving member 131 uses the transmission unit 132 to control the first clamping member 121 and the second clamping member 122 to move closer, so as to clamp and fix the single battery 200 located in the receiving cavity 123, thereby facilitating the processing of the single battery 200, and at the same time In the present application, a locking unit 140 is also provided for fixing the relative position relationship between the driving member 131 and the transmission unit 132, and further fixing the relative position relationship between the first clamping member 121 and the second clamping member 122, so as to eliminate the loosening problem of the first clamping member 121 and the second clamping member 122 caused by vibration, gravity and other reasons during the transportation of the layer clamp 100, ensure the overall clamping and fixing effect of the layer clamp 100, improve the clamping stability of the layer clamp 100, and finally improve the processing efficiency of the single cell 200.

[0053] In one embodiment, please refer to Figure 3 and Figure 8The above-mentioned driving member 131 has a rotating shaft portion 1312, and the driving member 131 is rotatably connected to the fixed seat 110 through the rotating shaft portion 1312 to facilitate the transmission connection between the driving member 131 and the transmission unit 132, thereby facilitating the driving member 131 to drive the transmission unit 132 to move, and finally facilitating the overall control of the layer clamp 100.

[0054] In one embodiment, the above-mentioned laminate clamp 100 has a first direction Z, a second direction Y and a third direction X that intersect each other. Preferably, the above-mentioned laminate clamp 100 has a first direction Z, a second direction Y and a third direction X that are perpendicular to each other. Here, "perpendicular" refers to a state where the angle formed by a straight line and a straight line, a straight line and a plane, or a plane and a plane is 89° to 91°.

[0055] For details, please refer to Figures 5 to 8 The driving member 131 has an inclined wall 1311 , which is inclined relative to the first direction Z, and the inclined wall 1311 is movably connected to the transmission unit 132 .

[0056] Furthermore, the above-mentioned transmission unit 132 includes: a follower 1321 and an elastic element 1322, the above-mentioned follower 1321 is arranged on the first clamping member 121, and the follower 1321 is movably connected to the inclined wall 1311; the elastic element 1322 abuts between the first clamping member 121 and the fixed seat 110; under the action of the driving member 131 and the elastic element 1322, a relative displacement occurs between the follower 1321 and the inclined wall 1311 to drive the first clamping member 121 and the second clamping member 122 to move closer or farther away.

[0057] The follower 1321 may be a roller, but is not limited thereto.

[0058] The elastic element may be any one of a spring, an elastic sheet or an elastic ball, but is not limited thereto.

[0059] It can be understood that the layer clamp 100 has two states: clamping and loosening. When the layer clamp 100 is in the clamping state, the first clamping member 121 and the second clamping member 122 clamp and fix the single battery 200 located in the receiving cavity 123; when the layer clamp 100 is in the loosening state, the first clamping member 121 and the second clamping member 122 loosen the single battery 200 located in the receiving cavity 123.

[0060] The driving member 131 can rotate clockwise or counterclockwise relative to the fixing base 110 .

[0061] When it is necessary to convert the layer clamp 100 from the loose state to the clamping state, the staff controls the driving member 131 to rotate clockwise, so that a relative displacement occurs between the follower 1321 and the inclined wall 1311, and the follower 1321 moves along the direction E, driving the first clamping member 121 to move synchronously along the direction E, so as to control the first clamping member 121 to approach the second clamping member 122, so that the first clamping member 121 and the second clamping member 122 cooperate to clamp the single battery 200 located in the receiving cavity 123, and at the same time, the elastic element 1322 abutting between the first clamping member 121 and the fixing seat 110 is compressed due to the relative displacement of the first clamping member 121, thereby generating a restoring elastic force;

[0062] When it is necessary to convert the layer clamp 100 from the clamping state to the loosening state, the staff controls the driving member 131 to rotate counterclockwise, the driving member 131 eliminates the force of the follower 1321, and at the same time, the reset elastic force of the elastic element 1322 drives the first clamping member 121 to move along the direction D, so that the first clamping member 121 is away from the second clamping member 122, so that the first clamping member 121 and the second clamping member 122 loosen the single battery 200 located in the receiving cavity 123, and at the same time synchronously drive the follower 1321 to move along the direction D, and the follower 1321 is reset.

[0063] For further information, please refer to Figure 6 to Figure 7 The above-mentioned inclined wall 1311 includes: a first inclined wall 13111 and a second inclined wall 13112, the first inclined wall 13111 and the second inclined wall 13112 are arranged at intervals in the second direction Y, and the follower 1321 is movably connected to the first inclined wall 13111 and the second inclined wall 13112 respectively.

[0064] Along the first direction Z, the distance between the first inclined wall 13111 and the first clamping part 121 in the third direction X becomes smaller, that is, the first inclined wall 13111 is inclined toward the direction close to the first clamping part 121; the distance between the second inclined wall 13112 and the first clamping part 121 in the third direction X becomes larger, that is, the second inclined wall 13112 is inclined toward the direction away from the first clamping part 121, that is, the inclination directions of the first inclined wall 13111 and the second inclined wall 13112 are opposite.

[0065] Among them, the above-mentioned first inclined wall 13111 and the second inclined wall 13112 can be a plane wall or an arc-shaped wall, but are not limited to this. No specific limitation is made in this application and can be specifically selected according to actual circumstances.

[0066] It can be understood that in the present application, multiple followers 1321 are respectively movably connected with multiple different inclined walls 13112, so as to facilitate the transmission connection between the driving member 131 and the followers 1321, and then facilitate the driving member 131 to control the first clamping member 121 and the second clamping member 122 to approach or move away, thereby improving the control efficiency of the driving member 131. At the same time, the present application reduces the distance between the first inclined wall 13111 and the first clamping member 121, that is, the first inclined wall 13111 is arranged in a direction close to the first clamping member 121, and increases the distance between the second inclined wall 13112 and the first clamping member 121, that is, the second inclined wall 13112 is arranged in a direction away from the first clamping member 121, so that when the driving member 131 rotates clockwise, the first clamping member 121 and the second clamping member 122 are close to each other, and when the driving member 131 rotates counterclockwise, the first clamping member 121 and the second clamping member 122 are moved away from each other, thereby further facilitating the control of the driving member 131.

[0067] It should be understood that the present application is not limited to reducing the distance between the first inclined wall 13111 and the first clamping part 121, that is, the first inclined wall 13111 is inclined in the direction close to the first clamping part 121, and the distance between the second inclined wall 13112 and the first clamping part 121 is increased, that is, the second inclined wall 13112 is inclined in the direction away from the first clamping part 121, and other inclination methods, for example, along the first direction Z, the distance between the first inclined wall 13111 and the first clamping part 121 in the third direction X is increased, that is, the first inclined wall 13111 is inclined in the direction away from the first clamping part 121, and the distance between the second inclined wall 13112 and the first clamping part 121 in the third direction X is reduced, that is, the second inclined wall 13112 is inclined in the direction close to the first clamping part 121. The first inclined wall 13111 and the first clamp 121 are arranged to be inclined, or the distance between the first inclined wall 13111 and the first clamp 121 in the third direction X, and the distance between the second inclined wall 13112 and the first clamp 121 in the third direction X are synchronously increased, that is, the first inclined wall 13111 and the second inclined wall 13112 are both arranged to be inclined away from the first clamp 121, or the distance between the first inclined wall 13111 and the first clamp 121 in the third direction X, and the distance between the second inclined wall 13112 and the first clamp 121 in the third direction X are synchronously decreased, that is, the first inclined wall 13111 and the second inclined wall 13112 are both arranged to be inclined toward the first clamp 121, etc., which can also realize the overall control of the layer clamp 100 by the driving member 131, and should also be regarded as an embodiment of the present application.

[0068] At the same time, the driving unit 130 in the present application is not limited to the above-mentioned mechanical structure. Other mechanical mechanisms, for example, adopting automatic control, directly adopting a cylinder, motor or electromagnet and other drivers for the driving unit 130, and the power output end of the driver is connected to the first clamping part 121 by transmission, and the first clamping part 121 and the second clamping part 122 can also be controlled to move closer or farther away, thereby achieving the effect in the present application, which should also be regarded as an embodiment of the present application.

[0069] For further information, please refer to Figure 5 The locking unit 140 includes a locking member 141 and a locking groove 142 which are arranged opposite to each other. The locking member 141 is arranged on the fixing seat 110 , and the locking groove 142 is opened on the driving member 131 .

[0070] Specifically, under the action of the driving member 131, the transmission unit 132 and the inclined wall 1311 are relatively displaced, so that the transmission unit 132 drives the first clamping member 121 and the second clamping member 122 to move closer or farther away, and the locking member 141 can be selectively located in the locking groove 142, so that the driving member 131 is locked by utilizing the cooperation between the locking member 141 and the locking groove 142, thereby realizing the overall locking of the layer clamp 100, ensuring the clamping stability of the layer clamp 100, and ultimately improving the processing efficiency of the single cell 200.

[0071] For further information, please refer again Figure 5 In one embodiment, the above-mentioned locking groove 142 includes: a first locking groove 1421 and a second locking groove 1422, and the first locking groove 1421 and the second locking groove 1422 are spaced apart in the first direction Z; under the action of the driving member 131, the locking member 141 can be optionally arranged in the first locking groove 1421 or the second locking groove 1422.

[0072] There are two first locking grooves 1421 and two second locking grooves 1422 , and the two first locking grooves 1421 are arranged at intervals in the second direction Y, and the two second locking grooves 142 are arranged at intervals in the second direction Y.

[0073] Two locking members 141 are provided, and the two locking members 141 are arranged in the second direction Y at an interval.

[0074] It can be understood that the layer clamp 100 has two states: clamping and loosening. When the layer clamp 100 is switched between the loosening state and the clamping state, the relative position relationship between the first clamping member 121 and the second clamping member 122 needs to be adjusted.

[0075] Specifically, when it is necessary to convert the layer clamp 100 from a loose state to a clamping state, the staff controls the driving member 131 to rotate clockwise, so that relative displacement occurs between the follower 1321 and the first inclined wall 13111, and between the follower 1321 and the second inclined wall 13112. The follower 1321 moves along the direction E, driving the first clamping member 121 to move synchronously along the direction E, so as to control the first clamping member 121 to approach the second clamping member 122, so that the first clamping member 121 and the second clamping member 122 cooperate to clamp the single battery 200 located in the accommodating cavity 123. At the same time, the elastic element 1322 abutting between the first clamping member 121 and the fixing seat 110 is compressed due to the relative displacement of the first clamping member 121, thereby generating a reset elastic force.

[0076] When the layer clamp 100 is in a clamping state, the locking member 141 close to the first inclined wall 13111 in the second direction Y is located in the second locking groove 1422, and the locking member 141 close to the second inclined wall 13112 in the second direction Y is located in the first locking groove 1421, so as to limit the locking member 141, and then limit and fix the driving member 131, and finally fix the relative position relationship between the first clamping member 121 and the second clamping member 122, so that the first clamping member 121 and the second clamping member 122 can clamp and fix the single battery 200, thereby ensuring the clamping stability of the layer clamp 100 and finally improving the processing efficiency of the single battery 200.

[0077] When it is necessary to convert the layer clamp 100 from the clamping state to the loosening state, the staff controls the driving member 131 to rotate counterclockwise, the driving member 131 eliminates the force of the follower 1321, and at the same time, the reset elastic force of the elastic element 1322 drives the first clamping member 121 to move along the direction D, so that the first clamping member 121 is away from the second clamping member 122, so that the first clamping member 121 and the second clamping member 122 loosen the single battery 200 located in the accommodating cavity 123, and at the same time, relative displacement occurs between the follower 1321 and the first inclined wall 13111, and between the follower 1321 and the second inclined wall 13112, so as to drive the follower 1321 to move along the direction D, and the follower 1321 is reset.

[0078] When the layer clamp 100 is in a loose state, the locking member 141 close to the first inclined wall 13111 in the second direction Y is located in the first locking groove 1421, and the locking member 141 close to the second inclined wall 13112 in the second direction Y is located in the second locking groove 1422, so as to limit the locking member 141 and then limit and fix the driving member 131, and finally realize the fixation of the relative position relationship between the first clamping member 121 and the second clamping member 122, so as to facilitate the taking and placing of the single battery 200.

[0079] In the present application, a first locking groove 1421 and a second locking groove 1422 are provided, so that the locking member 141 is respectively provided in the first locking groove 1421 and the second locking groove 1422, so that different states of the layer clamp 100 can be locked, further ensuring the overall clamping and fixing effect of the layer clamp 100, and improving the clamping stability of the layer clamp 100.

[0080] In one embodiment, please refer to Figures 1 to 3 The above-mentioned clamping units 120 are provided in multiple groups, and the multiple groups of clamping units 120 are arranged in the third direction X.

[0081] The driving unit 130 further includes a connecting member 133 , which extends along the third direction X, and the first clamping member 121 of each clamping unit 120 is fixedly connected to the connecting member 133 .

[0082] Among them, the connecting member 133 can be provided with one or more, and there is no specific limitation in this application, and it can be selected according to the actual situation.

[0083] It can be understood that the present application sets up multiple clamping units 120 so that the layer clamp 100 can synchronously clamp and fix multiple single cells 200, thereby improving the clamping effect of the layer clamp 100.
