[0024] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0025] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0026] In the present invention, unless otherwise specified, directional words such as "up, down, top, bottom" are usually used with reference to the directions shown in the drawings, or with reference to the components themselves in the vertical, perpendicular or gravity direction; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above directional words are not used to limit the present invention.

[0027] Obviously, the embodiments described above are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0028] In order to solve the problem of high battery core welding cost in the prior art, the utility model provides a welding mechanism.

[0029] like Figures 1 to 5 As shown, the welding mechanism includes a first transmission assembly 10, a lifting assembly 20, a welding assembly 30 and a first stop assembly 40. The first transmission assembly 10 is used to transmit the battery cell positioning carrier assembly 100, and the first transmission assembly 10 has a feed end and a discharge end. The lifting assembly 20 is arranged near the discharge end of the first transmission assembly 10 and can receive the battery cell positioning carrier assembly 100, and the lifting assembly 20 has an ascending position and a descending position. The welding assembly 30 is arranged above the lifting assembly 20 and can move in a direction close to or away from the lifting assembly 20. The first stop assembly 40 is located on the side of the lifting assembly 20 away from the first transmission assembly 10, and the first stop assembly 40 has a first stop state and a first avoidance state. When the lifting assembly 20 moves from the descending position to the ascending position, the welding assembly 30 moves toward the lifting assembly 20 and welds the battery cell positioning carrier assembly 100 on the lifting assembly 20. When the lifting assembly 20 moves from the raised position to the lowered position, the first stop assembly 40 switches from the first stop state to the first avoidance state.

[0030] By setting a first stop assembly 40 at the discharge end of the first transmission assembly 10 to stop the battery cell positioning carrier assembly 100 that needs to be welded, the battery cell positioning carrier assembly 100 is stopped by the first stop assembly 40 when it moves from the feed end to the discharge end, and the jacking assembly 20 moves from the lowered position to the raised position to drive the battery cell positioning carrier assembly 100 to move upward while the welding assembly 30 approaches the battery cell positioning carrier assembly 100 to complete welding, and then the jacking assembly 20 switches to the lowered position, and the first stop assembly 40 switches to the first avoidance state, so that the battery cell positioning carrier assembly after welding is completed. 100 output, one battery cell positioning carrier assembly 100 is welded at a time, and there is no need to rely on the visual recognition device in the prior art to identify the positions of multiple battery cells, thereby reducing the cost of the entire welding mechanism. In the prior art, the wires of small battery cells are thin and difficult to position, and they need to be manually positioned before welding to ensure the welding quality. However, the battery cell 103 of the present application is located on the battery cell positioning carrier assembly 100, and the positioning of the battery cell 103 has been completed and does not require manual positioning. The welding assembly 30 can directly weld the battery cell 103 after the battery cell positioning carrier assembly 100 is lifted by the lifting assembly 20.

[0031] It should be noted that the downstream in this application refers to Figure 2 The upstream is relatively close to the right side of the figure. Figure 2 It is relatively close to the left side of the figure.

[0032] In this embodiment, the first stop assembly 40 is a stop cylinder and is located downstream of the welding assembly 30. When the first stop assembly 40 switches to the first stop state, the first stop assembly 40 moves in the vertical direction close to the first transmission assembly 10, and finally a portion of the first stop assembly 40 extends, and the height of its top end is higher than the battery cell positioning carrier assembly 100, thereby stopping the battery cell positioning carrier assembly 100 when the battery cell positioning carrier assembly 100 reaches this position to prevent the battery cell positioning carrier assembly 100 from flowing out without welding; when the first stop assembly 40 switches to the first avoidance state, the first stop assembly 40 moves in the vertical downward direction, and the top end of the first stop assembly 40 is lower than the battery cell positioning carrier assembly 100, thereby avoiding the battery cell positioning carrier assembly 100 when the battery cell positioning carrier assembly 100 flows out.

[0033] In this embodiment, the first transmission assembly 10 includes multiple conveying sections connected in sequence, and the welding mechanism also includes multiple secondary stop assemblies. Each conveying section is respectively provided with at least one different secondary stop assembly, and the secondary stop assembly is used to stop the battery cell positioning carrier assembly 100 on the corresponding conveying section.

[0034] Specifically, there are multiple cell positioning carrier assemblies 100. By providing multiple different secondary stop assemblies on the conveying section, each corresponding to the multiple cell positioning carrier assemblies 100, an effective stopping function can be achieved. Preferably, when the jacking assembly 20 is in the lowered position, the top of the jacking assembly 20 is parallel to the bottom of the conveying section, thereby avoiding the cell positioning carrier assemblies 100.

[0035] like Figures 2 to 3 As shown, multiple sequentially connected conveying sections include a first conveying section 11 and a second conveying section 12. The lifting assembly 20 is located near the end of the first conveying section 11 away from the second conveying section 12. The secondary stop assembly includes a second stop assembly 50 and a third stop assembly 60. The second stop assembly 50 is located at the end of the first conveying section 11 away from the second conveying section 12 and has a second stop state and a second avoidance state. The third stop assembly 60 is located at the end of the second conveying section 12 near the first conveying section 11 and has a third stop state and a third avoidance state.

[0036] Specifically, the second conveying section 12, the first conveying section 11, and the lifting assembly 20 are arranged in sequence. The second stop assembly 50 is arranged at the beginning of the first conveying section 11 and is located near the lifting assembly 20. The third stop assembly 60 is arranged on the second conveying section 12 and is located near the end of the first conveying section 11. There are two second stop assemblies 50, one on each side of the first conveying section 11, and one third stop assembly 60, which is located on one side of the second conveying section 12. The second stop assembly 50 and the third stop assembly 60 are arranged on the top surface of the first transmission assembly 10 to stop or squeeze the battery cell positioning carrier assembly 100. Preferably, when the lifting assembly 20 is in the lowered position, the lifting assembly 20 is flush with the bottom of the first conveying section 11. In this embodiment, the third stop assembly 60 is arranged on one side of the second conveying section 12 and is located upstream of the welding assembly 30. The third stop assembly 60 is a cylinder, and the cylinder has an output end. When the third stop assembly 60 is in the third stop state, the output end of the cylinder extends and cooperates with the other side of the second conveying section 12 to squeeze and position the battery cell positioning carrier assembly 100; when the third stop assembly 60 is in the third avoidance state, the output end of the third stop assembly 60 is retracted, and the battery cell positioning carrier assembly 100 can move on the second conveying section 12.

[0037] like Figure 5 As shown, the second stop assembly 50 includes a second driving member 51 and a second stop member 52, which are drivably connected to each other and are L-shaped. When the second stop assembly 50 is in the second stop state, the two second driving members 51 actuate to cause the two second stop members 52 to abut against each other. The connecting section of the second stop member 52 is connected to the second driving member 51, and the length of the bent section is half the width of the first conveying section 11, thereby stopping the battery cell positioning carrier assembly 100. The third stop assembly 60 includes a third driving member 61 and a third stop member 62, which are drivably connected to each other. When the third stop assembly 60 is in the third stop state, the third driving member 61 actuates to drive the third stop member 62 to abut against the battery cell positioning carrier assembly 100. The third stop member 62 is connected to the side wall of the second conveying section 12, thereby clamping and positioning the battery cell positioning carrier assembly 100.

[0038] Optionally, the second driving member 51 and the third driving member 61 are cylinders or motors.

[0039] In this embodiment, the second stop member 52 is an L-shaped stop plate, the second driving member 51 is a clamping cylinder, and there are two second driving members 51 and the second stop members 52, which are correspondingly arranged on both sides of the second conveying section 12 and located upstream of the welding assembly 30. When the second stop assembly 50 is in the second stop state, the two second driving members 51 drive the two second stop members 52 to move along the width direction of the first conveying section 11 to achieve the two second stop members 52 approaching each other and forming an approximately U-shaped stop structure to stop the battery cell positioning carrier assembly 100; when the second stop assembly 50 is in the second avoidance state, the two second driving members 51 drive the two second stop members 52 away from each other, so that there is no obstacle in the middle position of the first conveying section 11, so that the battery cell positioning carrier assembly 100 passes through the first conveying section 11.

[0040] like Figures 1 to 3 As shown, the welding mechanism further includes a detection assembly 70 , which is signal-connected to the lifting assembly 20 , the second stop assembly 50 , and the third stop assembly 60 , respectively.

[0041] Specifically, the detection component 70 can detect the position of the battery cell positioning carrier component 100 in real time and drive the lifting component 20, the second stop component 50, and the third stop component 60 to operate. Optionally, the detection component 70 is an infrared detection component.

[0042] like Figure 1 and Figure 3 As shown, the detection assembly 70 includes a first detection portion 71, a second detection portion 72, and a third detection portion 73. The first detection portion 71 is provided corresponding to the lifting assembly 20, and the first detection portion 71 is respectively connected to the lifting assembly 20 and the second stop assembly 50 by signals. The second detection portion 72 is provided corresponding to the end of the first conveying section 11 close to the lifting assembly 20, and the second detection portion 72 is respectively connected to the second stop assembly 50 and the third stop assembly 60 by signals. The third detection portion 73 is provided corresponding to the end of the second conveying section 12 close to the first conveying end, and the third detection portion 73 is connected to the third stop assembly 60 by signals.

[0043] Specifically, when the lifting assembly 20 is in the lowered position and the first detection unit 71 detects the cell positioning carrier assembly 100, the cell positioning carrier assembly 100 is stopped by the first stop assembly 40. At this point, the first detection unit 71 drives the lifting assembly 20 upward, lifting the cell positioning carrier assembly 100, and the welding assembly 30 welds the cell positioning carrier assembly 100. Simultaneously, the second stop assembly 50 stops incoming material from the rear. When the second and third detection units 72 and 73 detect the cell positioning carrier assembly 100, they drive the third stop assembly 60 to stop the cell positioning carrier assembly 100.

[0044] In this embodiment, when the first detection part 71 detects the battery cell positioning carrier assembly 100, the second stop assembly 50 switches from the second avoidance state to the second stop state; and / or when the second detection part 72 and the third detection part 73 both detect the battery cell positioning carrier assembly 100, the third stop assembly 60 switches from the third avoidance state to the third stop state.

[0045] Specifically, the welding mechanism in the present application can simultaneously detect multiple battery cell positioning carrier assemblies 100. When there are multiple battery cell positioning carrier assemblies 100, when the first detection part 71 detects the battery cell positioning carrier assembly 100, the first detection part 71 drives the second stop assembly 50 to operate, thereby ensuring that there is only one battery cell positioning carrier assembly 100 at the position of the jacking assembly 20. When the second detection part 72 and the third detection part 73 simultaneously detect the battery cell positioning carrier assembly 100, the third detection part 73 drives the third stop assembly 60 to operate to clamp the battery cell positioning carrier assembly 100 at the position of the third stop assembly 60 to prevent multiple battery cell positioning carrier assemblies 100 from being squeezed between each other, especially when the jacking assembly 20 has lifted the battery cell positioning carrier assembly 100 for welding by the welding assembly 30, the third stop assembly 60 can prevent multiple battery cell positioning carrier assemblies 100 from squeezing the second stop member 52, causing the second stop assembly 50 to be unable to open.

[0046] In this embodiment, the welding assembly 30 is signal-connected to the first stopping assembly 40 .

[0047] Specifically, after completing welding, the welding assembly 30 sends a signal to the first stop assembly 40 , so that the first stop assembly 40 avoids the battery cell positioning carrier assembly 100 after welding.

[0048] like Figures 1 to 4 As shown, the welding mechanism further includes a second transmission assembly 80, which is located at one end of the first stop assembly 40 away from the lifting assembly 20, and the first transmission assembly 10 and the second transmission assembly 80 are located in the same straight line.

[0049] Specifically, the first transmission assembly 10 and the second transmission assembly 80 both include a belt 110 and a fourth driving member 120 . The fourth driving member 120 is driven and connected to the belt 110 . The battery cell positioning carrier assembly 100 is connected to the belt 110 to achieve movement of the battery cell positioning carrier assembly 100 .

[0050] In this embodiment, when the first detection unit 71 detects the battery cell positioning carrier assembly 100, the first detection unit 71 drives the second stop assembly 50 to stop the incoming material from the rear; because the battery cell positioning carrier assembly 100 is still stopped by the first stop assembly 40 and cannot leave, the jacking assembly 20 is actuated to lift the entire battery cell positioning carrier assembly 100, and the welding assembly 30 approaches the battery cell positioning carrier assembly 100 for welding; after welding is completed, the welding assembly 30 sends a signal to the jacking assembly 20 and the first stop assembly 40, and at this time, the jacking assembly 20 and the first stop assembly 40 are both lowered; The battery cell positioning carrier assembly 100 that has completed welding falls and flows out through the belt 110. After the battery cell positioning carrier assembly 100 that has completed welding flows out, the first detection unit 71 detects that there is no battery cell positioning carrier assembly 100 to be welded at this position, that is, there is no material. The first detection unit 71 drives the second stop assembly 50 to switch from the second stop state to the second avoidance state. The stopped battery cell positioning carrier assembly 100 to be welded flows to the top of the jacking assembly 20. At this time, the first detection unit 71 detects that there is material, thereby driving the second stop assembly 50 to switch from the second avoidance state to the second stop state.

[0051] Furthermore, the first stop assembly 40 is equipped with a timing sensor. Upon receiving a signal from the welding assembly 30, the first stop assembly 40 descends. After the timing expires, the first stop assembly 40 switches from the first avoidance state to the first stop state. When the second detection unit 72 detects that there is no material at the corresponding position, the second detection unit 72 drives the third stop assembly 60 to switch to the third avoidance state, allowing the battery cell positioning carrier assembly 100 to flow downward to the front side of the second stop assembly 50.

[0052] like Figures 1 to 4 As shown, the welding mechanism further includes a clamping assembly 90 , which is disposed at one end of the second transmission assembly 80 close to the first stop assembly 40 , and at least a portion of the clamping assembly 90 is movably disposed above the first stop assembly 40 .

[0053] Specifically, the clamping assembly 90 is arranged on the second transmission assembly 80. When the lifting assembly 20 lifts the battery cell positioning carrier assembly 100, the clamping assembly 90 is used to clamp the battery cell positioning carrier assembly 100 to prevent the battery cell positioning carrier assembly 100 from shaking during welding and affecting the welding effect.

[0054] like Figures 1 to 2 As shown, the clamping assembly 90 includes a clamping cylinder 91 and at least two clamping plates 92. The clamping cylinder 91 is mounted on the second transmission assembly 80. The two clamping plates 92 are spaced apart and positioned above the first stop assembly 40 along the width direction of the second transmission assembly 80. The clamping cylinder 91 is drivingly connected to the two clamping plates 92 and drives the two clamping plates 92 to move toward or away from each other.

[0055] Specifically, the clamping assembly 90 further includes a bracket 93 , which is connected to the second transmission assembly 80 . The clamping cylinder 91 avoids the battery cell positioning carrier assembly 100 and drives the two clamps 92 to move closer or further away, thereby clamping the battery cell positioning carrier assembly 100 .

[0056] like Figure 5 As shown, the battery cell positioning carrier assembly 100 includes a mounting plate 101 , a positioning member 102 , a battery cell 103 and a wire 104 .

[0057] Specifically, the positioning member 102 is detachably connected to the mounting plate 101. The positioning member 102 is provided with a positioning groove and a positioning hole for positioning the battery cell 103 and the wire 104. The wire 104 and the battery cell 103 are welded together during welding by the welding assembly 30. The size of the positioning member 102 is smaller than that of the mounting plate 101. When multiple battery cell positioning carrier assemblies 100 are arranged in sequence, the mounting plates 101 of the multiple battery cell positioning carrier assemblies 100 abut against each other. When the battery cell positioning carrier assemblies 100 are stopped or clamped, the second stopper 52 or the third stopper 62 abuts against the positioning member 102 to complete the stop. At least two clamping plates 92 abut against both sides of the positioning member 102 to clamp the positioning member 102, thereby avoiding stopping or clamping the battery cell positioning carrier assemblies 100 and interference between adjacent battery cell positioning carrier assemblies 100.

[0058] From the above description, it can be seen that the above embodiment of the present invention achieves the following technical effects: by setting a welding mechanism including a first transmission assembly 10, a lifting assembly 20, a welding assembly 30 and a first stop assembly 40, the first transmission assembly 10 is used to transmit the battery cell positioning carrier assembly 100, and the first transmission assembly 10 has a feeding end and a discharging end, the lifting assembly 20 is arranged near the discharging end of the first transmission assembly 10 and can receive the battery cell positioning carrier assembly 100, and the lifting assembly 20 has an ascending position and a descending position, and the welding assembly 30 is arranged on the lifting assembly 20 The first stop assembly 40 is located on the side of the jacking assembly 20 away from the first transmission assembly 10, and the first stop assembly 40 has a first stop state and a first avoidance state. When the jacking assembly 20 moves from the lowering position to the rising position, the welding assembly 30 moves toward the jacking assembly 20 and welds the battery cell positioning carrier assembly 100 on the jacking assembly 20. When the jacking assembly 20 moves from the rising position to the lowering position, the first stop assembly 40 switches from the first stop state to the first avoidance state. The first stop assembly 40 is set at the discharge end of the first transmission assembly 10 to stop the battery cell positioning carrier assembly 100 that needs to be welded. When the battery cell positioning carrier assembly 100 moves from the feed end to the discharge end, it is stopped by the first stop assembly 40. The jacking assembly 20 moves from the lowered position to the raised position to drive the battery cell positioning carrier assembly 100 to move upward. At the same time, the welding assembly 30 approaches the battery cell positioning carrier assembly 100 to complete the welding. Then the jacking assembly 20 switches to the lowered position, and the first stop assembly 40 switches to the first avoidance state, so that the battery cell positioning carrier assembly 100 after welding is completed. 0 output, one battery cell positioning carrier assembly 100 is welded at a time, and there is no need to rely on the visual recognition device in the prior art to identify the positions of multiple battery cells, thereby reducing the cost of the entire welding mechanism. In the prior art, the wires of small battery cells are thin and difficult to position, and they need to be manually positioned before welding to ensure the welding quality. However, the battery cell 103 of the present application is located on the battery cell positioning carrier assembly 100, and the positioning of the battery cell 103 has been completed and does not require manual positioning. The welding assembly 30 can directly weld the battery cell 103 after the battery cell positioning carrier assembly 100 is lifted by the lifting assembly 20.
