[0065] In order to make the purpose, technical scheme and advantages of the present application clearer, the embodiments of the present application will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiment is only one embodiment of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0066] "Embodiment" referred to herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present application. In the description of the embodiment of the present application, it should be understood that the terms "first", "second" and "third" etc. are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features. Thus, the features defined as "first", "second" and "third" etc. may include one or more of the features explicitly or implicitly. Moreover, the terms "first", "second" and "third" etc. are used to distinguish similar objects, and do not have to be used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiment of the present application described here can be implemented in an order other than illustrated or described here. In addition, the terms "including" and "for" and any of their variations are intended to cover non-exclusive inclusions.

[0067] like Figure 1 As shown, the present embodiment provides a linear material clamping device, including a pair of clamping mechanisms capable of moving toward each other, the clamping mechanism including a first clamping arm 12 and a second clamping arm 13, the first clamping arm 12 is provided with a first clamping surface, the second clamping arm 13 is provided with a second clamping surface, the first clamping surface and the second clamping surface are arranged opposite to each other, and the first clamping arm 12 and the second clamping arm 13 can be driven by a driving component 14 to move toward each other, so as to clamp the material between the first clamping surface and the second clamping surface. In one scenario of the present application, it is necessary to clamp long strips of material. The following is an example of a long strip of welding ribbon required in the production process of a battery cell. Usually, a battery cell needs to weld multiple areas at one time, so multiple welding ribbons need to be fed at the same time. Since multiple welding ribbons are fed at one time at the same time, the first clamping surface and the second clamping surface have space in the length direction to accommodate multiple welding ribbons at the same time.

[0068] like Figure 2-4As shown, in the equipment for producing battery cells, the space prepared for the mechanism for clamping the welding strip is limited, and the clamping mechanism is arranged above the welding strip. When clamping the welding strip, the first clamping arm 12 and the second clamping arm 13 need to be moved to the upper and lower sides of the welding strip respectively, and then the welding strip is clamped. Therefore, the first clamping arm 12 and the second clamping arm 13 are improved in this embodiment. Specifically, a plurality of first clamping jaws 121 are provided on the first clamping arm 12, and a plurality of second clamping jaws 131 and a plurality of first clamping jaw through holes 132 are provided on the second clamping arm 13. The plurality of first clamping jaws 121 can simultaneously pass through the plurality of first clamping jaw through holes 132 to realize the installation of the first clamping arm 12 and the second clamping arm 13, thereby realizing the synchronous movement of the first clamping arm 12 and the second clamping arm 13. At the same time, the second clamping jaw 131 is L-shaped, including a connecting portion 131A and a clamping portion 131B, and the second clamping surface is arranged on the end surface of the clamping portion 131B opposite to the first clamping surface, wherein the first clamping jaw 121 passes through the first clamping jaw through hole 132 and cooperates with the clamping portion 131B to clamp the welding strip.

[0069] like Figure 3 , 5 As shown, the second clamping arm 13 is movably mounted on the base 11, and a mounting portion 20 is provided at one end portion of the second clamping arm 13, and the mounting portion 20 includes at least one second guide groove 201, and the base 11 is provided with a mounting hole assembled with the second guide groove 201, and the second pin shaft 202 passes through the second guide groove 201 and is installed in the mounting hole on the base 11, and a third limiting portion 24 is provided at the other end of the second clamping arm 13 away from the mounting portion 20, and the third limiting portion 24 includes at least one limiting groove that can be adjusted in the horizontal direction, and the other end of the second clamping arm 13 is mounted on the base 11 by passing the pin shaft through the limiting groove. As a result, the second clamping arm 13 is movably mounted between the base 11, so that the second clamping arm 13 can realize reciprocating movement along the first direction on the base 11, and because the third limiting portion 24 has a hollow limiting groove, when the limiting groove abuts against the pin shaft and is maintained, the movement of the second clamping arm 13 in the first direction is terminated, thereby determining the end point of the first driving stroke. In order to further ensure the stability of the end point of the first driving stroke, a fourth limiting portion 25 is further provided on the base 11. The fourth limiting portion 25 includes an adjusting screw arranged at the far end of the base 11. One end of the adjusting screw abuts against a limiting block 241 fixedly mounted on the third limiting portion 24. The second clamping arm 13 is controlled at the end point of the first driving stroke by controlling the displacement of the adjusting screw toward the limiting block 241. Thus, through the coordinated action of the third limiting portion 24 and the fourth limiting portion 25, the second clamping arm 13 is precisely controllable at the end point position of the first driving stroke.

[0070] like Figure 3As shown, a pusher assembly 15 is installed at the output end of the driving assembly 14, and the pusher assembly 15 includes a guide portion 151 that is at least inclined, and a stop portion 16 is arranged on the first clamping arm 12, and the stop portion 16 can be a structure with a rolling or sliding contact surface such as a bearing and a cam, and the end surface of the guide portion 151 can contact the end surface of the stop portion 16. In this embodiment, the driving assembly 14 drives the pusher assembly 15 to move in a first direction. At this time, the inclined guide portion 151 can drive the stop portion 16 to drive the first clamping arm 12 to move in a second direction, and then when the driving assembly 14 drives the pusher assembly 15 to cause the guide portion 151 and the stop portion 16 to relative displace, the first clamping surface and the second clamping surface move toward each other in the second direction, thereby driving the first clamping jaw 121 and the clamping portion 131B to move toward each other to clamp the welding strip.

[0071] In order to achieve the first clamping arm 12 and the second clamping arm 13 being close to the welding strip at the same time and being respectively located on both sides of the welding strip, in this embodiment, a first limiting portion 18 is provided on the second clamping arm 13, and a second limiting portion 19 is provided on the pushing assembly 15. In this example, the second limiting portion 19 is a limiting groove, and the first limiting portion 18 is set to be L-shaped, one end of which is fixedly connected to the second clamping arm 13, and the other end is arranged in the limiting groove of the second limiting portion. When the driving assembly 14 drives the pushing assembly 15 to move along the first direction for the first driving stroke, the first The limiting portion 18 and the second limiting portion 19 are in contact and maintained, and the first clamp arm 12 and the second clamp arm 13 are synchronously moved along the first direction for a first distance. Thereafter, the driving component 14 drives the pushing component 15 to continue to move along the first direction for a second driving stroke. Since the second clamp arm 13 has been restricted in movement in the first direction by the third limiting portion 24 and the fourth limiting portion 25, the pushing component 15 can continue to drive the first clamp arm 12 and the second clamp arm 13 to move toward each other under the cooperation of the guide portion 151 and the stop portion 16, thereby completing the clamping of the welding strip.

[0072] In order to accurately control the moving path of the pusher assembly 15, a first guide groove 152 is provided on the pusher assembly 15, and a mounting hole assembled with the first guide groove 152 is provided on the base 11. The first pin shaft 153 passes through the first guide groove 152 and is installed on the base 11. The first pin shaft 153 and the first guide groove 152 can move relative to each other. The first guide groove 152 and the first pin shaft 153 provide motion guidance for the movement of the pusher assembly 15 in the first direction, ensuring that the pusher assembly 15 can move along a preset path in the first direction. In order to ensure the movement stability of the pusher assembly 15 in the first direction, the number of the first guide grooves 152 can be set to multiple, or set to an open concave groove, and the design of the movement stability of the pusher assembly 15 is achieved through the cooperation of rollers, bearings and other mechanisms with rolling cooperation and the concave grooves.

[0073] like Figure 4 As shown, a first reset mechanism 17 is provided on the first clamp arm 12, and the first reset mechanism 17 drives the first clamp arm 12 and the second clamp arm 13 to move in opposite directions, and is used to release the welding strip after the first clamping jaw 121 and the clamping portion 131B complete the positioning work of clamping the welding strip. A first clamping jaw mounting hole 122 is provided on the first clamp arm 12, and a third elastic reset mechanism 123 is provided in the first clamping jaw mounting hole 122. One end of the first clamping jaw 121 passes through the first clamping jaw mounting hole 122, and the other end abuts against the end surface of the third elastic reset mechanism 123. The third elastic reset mechanism 123 can provide a buffering force when clamping materials. In this embodiment, the first reset mechanism 17 and the third elastic reset mechanism 123 can be elastic mechanisms such as springs, spring sheets, elastic rubbers, and reset airbags.

[0074] like Figure 6 As shown, the second clamping arm 13 is further provided with a second reset mechanism 21 . In this embodiment, the second reset mechanism 21 can be a spring, a spring, an elastic rubber, a reset airbag or other elastic mechanism.

[0075] like Figure 6-7 As shown, an eccentric shaft fixing seat 22 is fixedly installed on the base 11, and a guide shaft 23 is arranged on the eccentric shaft fixing seat 22. Both ends of the guide shaft 23 pass through the two side plates of the eccentric shaft fixing seat 22 respectively to achieve fixation. An eccentric shaft guiding mechanism 154 is arranged at one end of the pushing assembly 15, and the eccentric shaft guiding mechanism 154 is slidably installed on the guide shaft 23. In this embodiment, two guide shafts 23 are provided, and the eccentric shaft guiding mechanism 154 is provided as an internal hollow frame, and through holes are respectively arranged at the top and the bottom. A pair of guide shafts 23 pass through the through holes of the eccentric shaft guiding mechanism 154 and are fixed on the two side plates of the eccentric shaft fixing seat 22 respectively, thereby realizing the installation of the eccentric shaft guiding mechanism 154 and the eccentric shaft fixing seat 22, and the eccentric shaft guiding mechanism 154 is slidably installed with a pair of guide shafts 23, so that the sliding of the eccentric shaft guiding mechanism 154 on the guide shaft 23 can be realized.

[0076] The driving assembly 14 includes a driving mechanism 141. In this embodiment, the driving mechanism 141 is a motor. The driving mechanism 141 is installed on the base 11. An eccentric shaft 142 is installed at the output end of the driving mechanism 141. The other end of the eccentric shaft 142 is connected to the pushing assembly 15. The eccentric shaft 142 is installed in a hollow frame of an eccentric shaft guide mechanism 154. Driven by the driving mechanism 141, the eccentric shaft 142 performs eccentric motion in the hollow frame of the guide mechanism 154, and can then drive the eccentric shaft guide mechanism 154 to reciprocate on the guide shaft 23, thereby driving the pushing assembly 15 to reciprocate in the first direction.

[0077] In combination with the scenario of clamping and positioning the long strip welding ribbon during the production process of the battery cell, the specific working principle of this embodiment is as follows: in the initial state, the first clamp arm 12 and the second clamp arm 13 are in a state of being separated, and there is a clamping space for clamping the welding ribbon between the first clamp jaw 121 and the clamping portion 131B. First, the driving component 14 drives the eccentric shaft 142 to move the eccentric shaft guide mechanism 154 along the first direction, thereby driving the pushing component 15 to drive the first clamp arm 12 and the second clamp arm 13 to approach the welding ribbon at the same time, and move the welding ribbon to the clamping space between the first clamp jaw 121 and the clamping portion 131B. Subsequently, the driving component 14 continues to The eccentric shaft 142 is continuously driven to apply a force to the eccentric shaft guide mechanism 154 to move in the first direction. After the first clamp arm 12 and the second clamp arm 13 move to the end point in the first direction, the first clamp arm 12 and the second clamp arm 13 are driven to move toward each other through the cooperation of the guide portion 151 and the stop portion 16, so that the first clamp jaw 121 and the clamping portion 131B apply a clamping force to the material. At the same time, multiple groups of first clamp jaws 121 and multiple groups of second clamp jaws 131 can move at the same time to clamp and position multiple welding strips. The entire mechanism is cleverly designed in structure and stable in operation. It can also clamp other wire-bound materials and has strong versatility.

[0078] like Figure 8 As shown, the present embodiment further provides a clamping device for linear materials, comprising: a lifting assembly 26, a base 11, a first clamping arm 12 and a second clamping arm 13, the base 11 is mounted on the lifting assembly 26, and a driving assembly 14 is also mounted on the base 11, the driving assembly 14 can drive the first clamping arm 12 and the second clamping arm 13 to perform two different driving strokes, the lifting assembly 26 can drive the driving assembly 14 to reciprocate in a second direction intersecting with the first direction; the lifting assembly 26 first drives the driving assembly 14 to approach the welding strip in the second direction, in the present embodiment, the lifting assembly 26 moves downward gradually to approach the welding strip, and makes the first clamping jaw 121 and the clamping portion 131B respectively located on the upper and lower sides of the welding strip in the three-dimensional space in the second direction, and at this time the welding strip does not enter the clamping space formed by the first clamping jaw 121 and the clamping portion 131B. In the first driving stroke, the driving component 14 drives the first clamp arm 12 and the second clamp arm 13 to move along the first direction until the welding strip is located in the clamping space between the first clamp jaw 121 and the clamping portion 131B, so that the first clamp jaw 121 and the clamping portion 131B are respectively located on both sides of the welding strip. In the second driving stroke, the driving component 14 continues to drive the first clamp arm 12 and the second clamp arm 13 to move toward each other along the second direction intersecting with the first direction, providing clamping force for the first clamp jaw 121 and the clamping portion 131B, thereby completing the clamping and fixation of the welding strip.

[0079] The above embodiments are only for illustrating the technical concept and features of the present application, and their purpose is to enable people familiar with this technology to understand the content of the present application and implement it accordingly, and they cannot be used to limit the scope of protection of the present application. For those skilled in the art, it is obvious that the present application is not limited to the details of the above exemplary embodiments, and the present application can be implemented in other specific forms without departing from the spirit or basic features of the present application. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive.
