[0028] In order to facilitate the understanding of the present application, the present application will be described more fully below with reference to the accompanying drawings. Preferred embodiments of the present application are shown in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0029] It should be noted that when an element is referred to as "provided on" another element, it can be directly on the other element or there can be a middle element. When an element is referred to as "connected" to another element, it can be directly connected to the other element or there can be a middle element.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terminology used in the specification of the present application herein is only for the purpose of describing specific embodiments and is not intended to limit the present application.

[0031] As Figures 1 to 7As shown, the welding strip clamping and correcting mechanism disclosed in the present application comprises a base, a lifting driving element 200, a jaw set 300, a limiting element 400, a pressing element 500 and a plurality of strip pressing elements 600.

[0032] Specifically, the lifting driving element 200 and the jaw set 300 are arranged on the base, the limiting element 400 is slidably arranged on the base, the limiting element 400 and the pressing element 500 are connected with the driving end of the lifting driving element 200, the base is provided with a plurality of grooves, the sliding ends of the plurality of strip pressing elements 600 are correspondingly and elastically arranged in the plurality of grooves, the plurality of strip pressing elements 600 and the plurality of jaws 320 of the jaw set 300 are correspondingly and spacedly arranged along the first direction, along the gravity direction, the plurality of limiting grooves A of the limiting element 400 and the plurality of jaws 320 are correspondingly arranged, the pressing end of the pressing element 500 is arranged opposite to the plurality of strip pressing elements 600, and the first direction is perpendicular to the gravity direction.

[0033] In the strip clamping process of the welding strip clamping and correcting mechanism, the lifting driving element 200 drives the limiting element 400 and the pressing element 500 to move along the gravity direction by a first distance, the pressing end of the pressing element 500 is in hard contact with the plurality of strip pressing elements 600, the plurality of limiting grooves A of the limiting element 400 are in limiting cooperation with the plurality of jaws 320, so that the plurality of jaws 320 are all in the open state and correspondingly opposite to the plurality of welding strips on the strip carrier table, the plurality of strip pressing elements 600 correspondingly press the flattened sections of the plurality of welding strips on the strip carrier table, thereby avoiding the welding strip flattened section from rotating due to its own stress after deformation, so that the strip pressing element 600 corrects the welding strip, then the lifting driving element 200 drives the limiting element 400 and the pressing element 500 to move along the direction opposite to the gravity direction by the first distance, the plurality of limiting grooves A of the limiting element 400 are away from the plurality of jaws 320, and the plurality of jaws 320 are in the closed state and clamp the welding strip.

[0034] The above structure drives the limiting element 400 and the pressing element 500 by the lifting driving element 200, so that before the jaw set 300 clamps the plurality of welding strips, the plurality of welding strips are first corrected and adjusted by the plurality of strip pressing elements 600, to ensure that the flattened sections of the plurality of welding strips do not overturn, and the flattened surfaces of the flattened sections of the plurality of welding strips clamped by the plurality of jaws 320 correspondingly have consistent directions, so that the battery string prepared by the welding strip will not scratch the battery sheet in the lamination process.

[0035] In an alternative scheme, the lifting drive 200 can be an electric cylinder which can drive the limiting member 400 and the pressing member 500 to move by any distance. In another alternative scheme, the lifting drive 200 can include two double-stroke cylinders which are arranged at two ends of the base, and the limiting member 400 and the pressing member 500 are connected with the driving ends of the two double-stroke cylinders. In the above structure, the double-stroke cylinders can not only realize the reciprocating movement of the limiting member 400 and the pressing member 500 by different distances, but also ensure the smooth movement of the limiting member 400 and the pressing member 500 when the two double-stroke cylinders are simultaneously driven.

[0036] In the embodiment of the present application, the jaw group 300 can include a mounting seat 310 and a plurality of jaws 320. Specifically, the mounting seat 310 is arranged on the base, and the plurality of jaws 320 are arranged in an array and hingedly arranged on the mounting seat 310, so as to simultaneously clamp a plurality of solder strips.

[0037] In a further technical scheme, a plurality of bending protrusions 330 can be arranged in an array on the mounting seat 310. Specifically, the plurality of pressing members 600, the plurality of bending protrusions 330 and the plurality of jaws 320 are arranged in a one-to-one correspondence and in sequence along the first direction. The bending protrusions 330 are used to bend the solder strips before the plurality of battery pieces and the plurality of solder strips are welded, so that a part of the solder strip can extend into the back surface of the adjacent battery piece during the lamination.

[0038] After the solder strip clamping and correcting mechanism places the solder strips on the lamination table, the lifting drive 200 drives the limiting member 400 and the pressing member 500 to move along the gravity direction by a second distance which is smaller than the first distance. The plurality of pressing members 600 are correspondingly pressed on the flattened sections of the plurality of solder strips, and elastically contract in the direction opposite to the gravity direction when the solder strip clamping and correcting mechanism is lowered and contacts the lamination table. The plurality of bending protrusions 330 move to contact and bend the plurality of solder strips in a one-to-one correspondence. At this time, the limiting member 400 is in contact with the plurality of jaws 320, so that the plurality of jaws 320 are all in a half-open state, thereby preventing the solder strip clamping and correcting mechanism from lifting the solder strips and causing the solder strips to be skewed or misaligned when the solder strip clamping and correcting mechanism is withdrawn.

[0039] In addition, the lamination table can carry a plurality of battery pieces and solder strips to form a to-be-welded battery string. By driving the plurality of battery pieces to move close to each other, the battery string can meet the requirements of the string type. At the same time, the front and rear sections of the solder strips can be respectively overlapped on the front surfaces and back surfaces of the adjacent two battery pieces, so as to facilitate the whole-string welding by the welding head. The lamination table is a prior art, and its specific structure will not be described in detail here.

Specifically, one end of the belt pressing rod 610 is slidably arranged in the groove, the other end of the belt pressing rod 610 extends out of the base, and the first spring 620 is sleeved on one end of the belt pressing rod 610. In the direction of gravity, the two ends of the first spring 620 are elastically contacted with the boss of one end of the belt pressing rod 610 and the inner wall of the groove, respectively.

[0041] Of course, the belt pressing member 600 can be a flexible deformation belt pressing member 600, such as a silica gel belt pressing member 600, a sponge belt pressing member 600, etc., and the present application does not make any limitation thereto.

[0042] In the embodiment of the present application, the base can include a first base plate 110 and a second base plate 120.

[0043] In a further technical solution, the welding belt clamping and correcting mechanism can further include a connecting block 700 and an adjusting screw rod seat 800. The first base plate 110 is provided with a threaded hole, the second base plate 120 is provided with a strip-shaped hole, a screw is threadedly connected with the threaded hole and the strip-shaped hole, the connecting block 700 is arranged on the second base plate 120, and the adjusting screw rod seat 800 is arranged on the second base plate 120. The adjusting screw rod seat 800 and the connecting block 700 are threadedly connected.

[0044] By rotating the adjusting screw rod to make it away from or close to the connecting block 700, the first base plate 110 and the second base plate 120 can be relatively displaced, so as to adjust the clamping position of the jaw group 300, thereby facilitating the preparation of battery strings of different string types.

[0045] In the embodiment of the present application, the jaw 320 can include a second spring, a first sub-jaw 320 and a second sub-jaw 320. Specifically, the first sub-jaw 320 and the second sub-jaw 320 are both rotatably arranged on the mounting seat 310, the first sub-jaw 320 and the second sub-jaw 320 are hingedly connected, and the two ends of the second spring are elastically contacted with one end of the first sub-jaw 320 and the second sub-jaw 320 close to the limiting member 400, respectively.

[0046] As shown in Figure 8 The present application also discloses a welding belt conveying device. The disclosed welding belt conveying device includes a support 910, a telescopic driving member 920, a welding belt clamping jaw and the welding belt clamping and correcting mechanism described above. Specifically, the telescopic driving member 920 and the welding belt clamping jaw are both arranged on the support 910, and the base is connected with the driving end of the telescopic driving member 920.

[0047] In the process of the welding strip carrying device clamping the welding strip, the welding strip clamping jaw clamps the adjacent front and rear sections of the flattened section, the lifting driving element 200 drives the limiting element 400 and the pressing element 500 to move in the direction opposite to the gravity direction by a first distance, the plurality of limiting grooves A of the limiting element 400 are away from the plurality of clamping jaws 320, the plurality of clamping jaws 320 are in the closed state and clamp the welding strip, and the pressing element 500 is also away from the plurality of pressing elements 600, and the plurality of pressing elements 600 are in elastic contact with the flattened sections of the plurality of welding strips.

[0048] After the welding strip carrying device places the welding strip, the clamping jaws of the welding strip clamping jaw are all in the open state, the lifting driving element 200 drives the limiting element 400 and the pressing element 500 to move in the direction opposite to the gravity direction by a second distance, the second distance is less than the first distance, the telescopic driving element 920 drives the welding strip clamping and correcting mechanism to descend, the plurality of pressing elements 600 are correspondingly pressed on the plurality of flattened sections of the welding strip, and the plurality of pressing elements 600 are elastically contracted in the direction opposite to the gravity direction due to the abutting of the pressing element 600 and the tablet table, and the plurality of bending protrusions 330 are moved to be in contact with and bent with the plurality of welding strips one by one.
