[0050] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0051] The above and other technical contents, features and effects of the present invention will be clearly presented in the following detailed description of the embodiments with reference to the accompanying drawings. The directional terms mentioned in the following embodiments, such as up, down, left, right, front or back, etc., are only the directions of the reference drawings. Therefore, the directional terms used are used to illustrate and not to limit the present invention. In addition, in all embodiments, the same reference numerals represent the same elements.

[0052] Embodiment 1

[0053] Reference Figure 1 As shown, a clamping and positioning module comprises:

[0054] A first positioning assembly includes a passive component 501 and a reset component elastically connected to the passive component 501, and the passive component 501 moves along a first direction under the action of an external force;

[0055] The second positioning component is hinged to the first positioning component. When the passive component 501 moves along the first direction under the action of external force, the first positioning component drives the second positioning component to move along the second direction at the same time, and there is an angle between the first direction and the second direction.

[0056] The present embodiment provides a clamping and positioning module, which is generally provided in pairs. The two clamping and positioning modules are provided on opposite sides of the product. When an external force acts on the passive component 501, the passive component 501 will retreat along the first direction and squeeze the reset component. At the same time, the passive component 501 drives the second positioning component to open along the second direction. When the external force no longer acts on the passive component 501, the reset component is reset. At the same time, the passive component 501 drives the second positioning component to gather along the second direction, thereby positioning the product from the side of the product with stable accuracy and reduced load on the product.

[0057] In this embodiment, the first positioning assembly also includes an opening plate 502, the passive component 501 is arranged on the opening plate 502, and the reset assembly includes a check block 505 and at least one elastic element 504, one end of the elastic element 504 abuts the check block 505, and the other end of the elastic element 504 abuts the opening plate 502.

[0058] Among them, the passive component 501 can be adopted as follows Figure 1 The roller shown in FIG. 50 is a rectangular plate. The shape of the check block 505 is a rectangle.

[0059] The elastic element 504 can be a spring, and one end of the elastic element 504 outside the opening plate 502 is a fixed end, that is, one end of the elastic element 504 abuts against the check block 505 and cannot be pushed, so the elastic force generated by compression will push the opening plate 502. There are two elastic elements 504, and the parameters of the two elastic elements 504 are the same. The selection of two elastic elements 504 can withstand a larger load. At the same time, since the force between the two elastic elements 504 is balanced, the stability of the reset component can be improved; and since the use of two elastic elements 504 can better withstand loads and vibrations, the service life of the reset component will be relatively longer. Of course, when one of the elastic elements 504 fails and cannot work, the other elastic element 504 can also work normally.

[0060] In order to describe the relationship between the various parts and components, a local coordinate system is established with the center point of the first positioning component as the coordinate origin, with the length direction of the open plate 502 as the X-axis direction, and the width direction of the open plate 502 as the Y-axis direction. It can be understood that the first direction is the X-axis direction, and the second direction is the Y-axis direction. Figure 1 The directions of the arrows.

[0061] In this embodiment, the reset assembly further includes at least one first sliding unit 503 disposed at the bottom of the opening plate 502, and the first sliding unit 503 is disposed along the first direction, i.e., the X-axis direction; the first sliding unit 503 includes a first guide rail and a first slider sliding along the first guide rail, and the first guide rail is disposed along the first direction, i.e., the X-axis direction. Figure 1 As shown, there are two first sliding units 503, and the two first sliding units 503 are respectively arranged on both sides of the bottom of the opening plate 502. Preferably, the two first sliding units 503 are symmetrically arranged with respect to the central axis of the opening plate 502, which can ensure that the opening plate 502 can remain stable during the movement along the first direction without deflection.

[0062] In this embodiment, if Figure 1 As shown, the second positioning assembly includes a connecting plate 506 and a side opening plate 507, and the two sides of the connecting plate 506 are rotatably connected to the opening plate 502 and the side opening plate 507, respectively, and the side opening plate 507 is hinged to the opening plate 502. Among them, one side of the connecting plate 506 is bolted to the opening plate 502, and the other side of the connecting plate 506 is bolted to the side opening plate 507, and the connecting plate 506 is arranged at an angle to the opening plate 502 and the side opening plate 507. It should be noted that those skilled in the art can adjust the position of the connecting plate 506 on the opening plate 502 and the side opening plate 507 as needed, for example, the connecting plate 506 is arranged parallel to the opening plate 502 and the side opening plate 507.

[0063] In this embodiment, at least one second sliding unit 508 is provided at the bottom of the side opening plate 507, and the second sliding unit 508 is arranged along the second direction, namely, the Y-axis direction; the second sliding unit 508 includes a second guide rail and a second slider sliding along the second guide rail, and the second guide rail is arranged along the second direction, namely, the Y-axis direction, which can ensure that the side opening plate 507 can remain stable during the movement along the second direction without deflection.

[0064] Furthermore, combined with Figure 2 and Figure 3 The clamping and positioning module also includes a first auxiliary positioning member connected to the first positioning assembly, and the first auxiliary positioning member moves along the first direction with the passive member 501 under the action of an external force. Specifically, this embodiment is described by clamping and positioning a square battery cell 900. Since the battery cell 900 is to be subjected to a tab ultrasonic welding process, the battery cell 900 mainly includes a top cover and a winding core, and the first auxiliary positioning member is a first positioning plate 602 or a second positioning plate 603. Figure 4 As shown, the first positioning plate 602 includes a main body 6021, which is provided with two first notches 6022 for avoiding the poles (i.e., the positive pole and the negative pole) of the battery cell 900 and a second notch 6023 for avoiding the explosion-proof valve of the battery cell 900, and is used to clamp the top cover of the battery cell 900. Figure 5 As shown, the second positioning plate 603 is a plate member in a trapezoidal shape, which is used to clamp the bottom of the winding core of the battery cell 900. Of course, the second positioning plate 603 can also be a plate member in a rectangular shape, and the length of the side of the plate member close to the battery cell 900 can be designed according to the length of the winding core of the battery cell 900 to be clamped. It can be understood that when it is necessary to clamp and correct the battery cells 900 of different sizes, the first auxiliary positioning member and / or the second auxiliary positioning member can be replaced.

[0065] It should be noted that when the clamping and positioning module clamps and positions other products, the structural form of the first auxiliary positioning member can be designed according to the structural characteristics of the product.

[0066] Furthermore, the clamping and positioning module also includes a second auxiliary positioning member 601 connected to the second positioning assembly, and the second auxiliary positioning member 601 moves along the second direction with the second positioning assembly. Specifically, the second auxiliary positioning member 601 includes a first connecting member 6011 and a second connecting member 6012 that are bent, wherein the first connecting member 6011 is connected to the second positioning assembly. The second auxiliary positioning member 601 is used to clamp the side of the battery cell 900, and the first auxiliary positioning member and the second auxiliary positioning member 601 position the top, bottom, left, and right of the battery cell 900, which can ensure the stability and accuracy of the product during the processing; and generally, the first auxiliary positioning member and the second auxiliary positioning member 601 are used for four-side positioning, which is suitable for workpieces of various shapes, including circular and polygonal shapes.

[0067] In this embodiment, the clamping and positioning module is made of non-metallic insulating material to prevent the battery cell 900 from being scratched during the alignment process. In addition, the clamping and positioning module has a moderate gripping force and does not affect the performance of the battery cell 900 itself.

[0068] The working principle of this embodiment is as follows:

[0069] Two clamping and positioning modules are arranged on opposite sides of the battery cell 900 .

[0070] An external force is applied to the passive component 501, that is, the passive component 501 is squeezed and retreats in the first direction, driving the opening plate 502 to retreat in the first direction, and at the same time squeezing the elastic element 504, the elastic element 504 is compressed, and the check block 505 resists the elastic element 504 to prevent it from retreating further. The retreat force of the opening plate 502 is converted into a force in the second direction of the side opening plate 507 through the connecting plate 506, and the side opening plate 507 is opened in the second direction, that is, the distance between the side opening plate 507 and the opening plate 502 increases. At the same time, the first positioning component drives the first auxiliary positioning component to open in the first direction, and the second positioning component drives the second auxiliary positioning component 601 to open in the second direction, and a position for placing the battery cell 900 is vacated between the two clamping positioning modules.

[0071] The external force on the passive component 501 is removed, that is, the passive component 501 is no longer squeezed, and the elastic element 504 returns to its original shape. The elastic element 504 drives the opening plate 502 to move forward in the first direction. At the same time, during the forward movement of the opening plate 502, the force is converted into the second direction of the side opening plate 507 through the connecting plate 506. The side opening plate 507 gathers along the second direction, toward the opening plate 502, that is, the distance between the side opening plate 507 and the opening plate 502 is reduced, and the first positioning component drives the first auxiliary positioning component to gather along the first direction toward the center of the battery cell 900, and the second positioning component drives the second auxiliary positioning component 601 to gather along the second direction toward the center of the battery cell 900, thereby realizing the upper, lower, left and right positioning of the battery cell 900.

[0072] Embodiment 2

[0073] like Figure 6 As shown, this embodiment provides a positioning mechanism, including:

[0074] The transplanting mechanism includes a shift fork 400, and the shift fork 400 is connected to a lifting drive source;

[0075] The clamping and positioning module 500 provided in the first embodiment;

[0076] The shift fork 400 is configured to descend, squeeze, clamp, and hold the passive component 501 on the positioning module 500 under the control of the lifting drive source, so that the passive component 501 moves along the first direction.

[0077] This embodiment provides a positioning mechanism, which cooperates with the clamping positioning module 500 when placing the battery cell 900 through the transplanting mechanism to achieve synchronous positioning of the battery cell 900, shorten the positioning time of the battery cell 900, and improve the positioning efficiency of the positioning mechanism.

[0078] In this embodiment, if Figure 7 As shown, the transplanting mechanism also includes a first mounting plate 701, a connecting seat 702, a second mounting plate 703 and a connecting column 704; the first mounting plate 701 and the second mounting plate 703 are arranged in parallel; one end of the connecting column 704 abuts the first mounting plate 701, and the other end of the connecting column 704 abuts the second mounting plate 703; the connecting seat 702 includes a first connecting portion and a second connecting portion arranged on both sides of the first connecting portion, wherein the first connecting portion and the second mounting plate 703 are fixedly connected, and the second connecting portion is located on both sides of the second mounting plate 703.

[0079] In this embodiment, the transplanting mechanism further includes a manipulator 300 connected to a lifting drive source, and the fork 400 is fixed to the manipulator 300. The lifting drive source can be a linear motion module such as an electric cylinder or a pneumatic cylinder, which can be selected and adjusted by those skilled in the art as needed.

[0080] Specifically, the manipulator 300 includes a lift seat 301 that can be raised and lowered and is arranged at the second connection part of the connection seat 702, and a clamp 302 that is slidably connected to the lift seat 301; the clamp 302 is located on the side opposite to the product to be positioned, and the fork 400 is located on the other side opposite to the product to be positioned. Among them, the lift seat 301 can be connected to the movable part of a linear motion module such as a cylinder, so as to realize the descent of the lifting and transplanting mechanism. After the fork 40 reaches the extreme position, the manipulator 300 also reaches the specified position at the same time, and the manipulator 300 cannot continue to descend. In order to avoid the fork 400 being in place and the battery cell 900 grasped by the manipulator 300 being too far away from the product placement area, the manipulator 300 can be lowered twice through the lift seat 301, and the clamp 302 gently places the battery cell 900 in the product placement area.

[0081] Furthermore, the transplanting mechanism also includes a rotary drive source 100 and a horizontal drive source 200 connected to the output end of the rotary drive source 100, and the horizontal drive source 200 has a movable part for connecting the manipulator 300. Among them, the action part of the rotary drive source 100 is connected to the first mounting plate 701, and the horizontal drive source 200 is arranged between the first mounting plate 701 and the first connecting part of the connecting seat 702. It should be noted that the main reason for the rotary drive source 100 to be arranged in the transplanting mechanism is that the direction of the battery cell 900 when it comes from the previous process is not consistent, and it needs to be adjusted according to the incoming direction of the battery cell 900 so that the manipulator 300 can grab the battery cell 900. The rotary drive source 100 can adopt a rotary cylinder, and the horizontal drive source 200 can adopt a linear module, which can be selected and adjusted by those skilled in the art according to needs.

[0082] In this embodiment, the shift fork 400 is fixed to both sides of the second mounting plate 703, and the manipulator 300 is located on one side opposite to the second mounting plate 703, and the shift fork 400 is located on the other side opposite to the second mounting plate 703. The shift fork 400 includes a support rod 401, and an extrusion portion 402 is provided at the end of the support rod 401. The extrusion portion 402 has a mating surface for extruding the passive component 501. Since the passive component 501 adopts a roller, the mating surface of the extrusion portion 402 is an inclined surface. When the shift fork 400 extrudes the passive component 501, the passive component 501 moves on the inclined surface profile of the extrusion portion 402.

[0083] In this embodiment, combined with Figure 6 and Fig.10 The positioning mechanism also includes a support frame 509 with a product placement area and positioning devices respectively arranged on both sides of the product placement area; the positioning device includes a positioning seat 604 with a positioning hole 605 and a positioning pin 606 arranged on the positioning seat 604. The positioning seat 604 and the support frame 509 adopt a sliding fit. Specifically, a guide rail is arranged at the bottom of the positioning seat 604, and a slide groove is correspondingly arranged on the support frame 509. The guide rail moves in the slide groove to facilitate the adjustment of the position of the positioning device. When the positioning device is adjusted to a suitable position, the positioning hole 605 of the positioning seat 604 can be passed through by bolts and connected with the support frame 509. Among them, the two positioning devices are arranged on one side opposite to the product placement area, and the two clamping positioning modules 500 are arranged on the other side opposite to the product placement area. It can be understood that the two positioning devices and the two clamping positioning modules 500 are arranged around the product placement area.

[0084] Furthermore, if Fig.10 As shown, both sides of the positioning seat 604 extend toward the product placement area to form an extension portion 6041 , and the extension portion 6041 can support a portion of the battery cell 900 .

[0085] Furthermore, if Figure 6As shown, the positioning mechanism further includes a base 800 that supports the support frame 509 .

[0086] The working principle of this embodiment is as follows:

[0087] Combination Figure 8 and Fig. 9 , the manipulator 300 descends, the passive component 501 is squeezed and retreats in the first direction, driving the opening plate 502 to retreat in the first direction, and at the same time squeezing the elastic element 504. The elastic element 504 is compressed, and the check block 505 resists the elastic element 504 to prevent it from retreating further. The retreat force of the opening plate 502 is converted into a force in the second direction of the side opening plate 507 through the connecting plate 506. The side opening plate 507 opens in the second direction, that is, the distance between the side opening plate 507 and the opening plate 502 increases. At the same time, the first positioning component drives the first auxiliary positioning component to open in the first direction, and the second positioning component drives the second auxiliary positioning component 601 to open in the second direction. A space for placing the battery cell 900 is vacated between the two clamping and positioning modules 500. At this time, the clamping and positioning module 500 is in the first state, such as Fig. 9 shown.

[0088] The manipulator 300 rises, the passive component 501 is no longer squeezed, and the elastic element 504 returns to its original shape. The elastic element 504 drives the opening plate 502 to move forward in the first direction. At the same time, the opening plate 502 moves forward and is converted into a force in the second direction of the side opening plate 507 through the connecting plate 506. The side opening plate 507 gathers along the second direction, toward the opening plate 502, that is, the distance between the side opening plate 507 and the opening plate 502 is reduced. The first positioning component drives the first auxiliary positioning component to gather along the first direction toward the center of the battery cell 900, and the second positioning component drives the second auxiliary positioning component 601 to gather along the second direction toward the center of the battery cell 900. At this time, the clamping positioning module 500 is in the second state (not shown in the figure), thereby realizing the upper, lower, left and right positioning of the battery cell 900.

[0089] As can be seen from the above, under the control of the transplanting mechanism, the positioning mechanism rotates and rises, moves smoothly and accurately, and realizes reliable positioning and clamping of the battery cell 900 in preparation for welding. The accuracy of positioning directly affects the accuracy of reaching the welding position. If the positioning is inaccurate, it is difficult to ensure the welding quality. Therefore, the positioning mechanism provided in this embodiment cooperates with the clamping and positioning module 500 when placing the battery cell 900 through the transplanting mechanism to ensure the positioning accuracy. The design of the clamping and positioning module 500 is equally important to ensure that the battery cell 900 is clamped but not damaged.

[0090] It should be noted that this embodiment is described by positioning the battery cell 900, and the positioning mechanism provided in this embodiment is also applicable to positioning other products.

[0091] In the description of the embodiments of the present utility model, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set" and "connection" should be understood in a broad sense, for example, it can be connected, detachably connected, or integrally connected; it can be mechanically connected or electrically connected; it can be directly connected, or indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0092] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the invention of the utility model.
