[0058] Working principle of the present invention:

[0059] like Figure 1 As shown, the circulating conveyor line can be fully seen, and the loading assembly, the pressing assembly, the welding assembly, and the unloading assembly are arranged in sequence along the conveying direction of the circulating conveyor line. Among them, in this embodiment, the first conveyor line 1 corresponding to the loading assembly is provided with an unlocking mechanism, and the second conveyor line 2 and the third conveyor line 3 corresponding to the unloading assembly are provided with unlocking mechanisms.

[0060] In this embodiment, Figure 2 As shown in the figure, the three parallel arrows from left to right in the figure are the conveying direction of the first conveyor line 1, the conveying direction of the second conveyor line 2, and the conveying direction of the third conveyor line 3, respectively. Figure 2 The arrow direction of the first Y-axis moving mechanism 6 on the upper middle side is the conveying direction of the moving end of the first Y-axis moving mechanism 6. Figure 2 The arrow direction of the second Y-axis moving mechanism 7 on the lower middle side is the conveying direction of the moving end of the second Y-axis moving mechanism 7, that is, the fixture base 8 can be transferred from the first conveyor line 1 to the second Y-axis moving mechanism 7, and the second Y-axis moving mechanism 7 can transfer the fixture base 8 to one end of the second conveyor line 2 or one end of the third conveyor line 3. The second conveyor line 2 and the third conveyor line 3 both transfer the fixture base 8 toward the direction of the first Y-axis moving mechanism 6. Finally, the first Y-axis moving mechanism 6 can transfer the fixture base 8 back to the first conveyor line 1 to form a circular conveyor line. In this embodiment, the conveying direction of the first conveyor line 1, the conveying direction of the second conveyor line 2, and the conveying direction of the third conveyor line 3 are all in the Y-axis direction (that is, Figure 2 The conveying direction of the first Y-axis moving mechanism 6 and the conveying direction of the second Y-axis moving mechanism 7 are both in the X-axis direction (i.e. Figure 2 left and right directions). Figure 2 The dotted box on the middle right is an enlarged schematic diagram.

[0061] In this embodiment, the X-axis feeding mechanism 13 can drive the Z-axis feeding mechanism 14 to move along the X-axis direction, and the Z-axis feeding mechanism 14 can drive the feeding clamp 15 to move along the Z-axis direction. Figure 3In the direction of up and down lifting, the X-axis loading mechanism 13 is located above the first conveyor line 1. Therefore, the external battery core module 50 can be clamped by the loading claw 15 to the mold unit corresponding to the clamp base 8 on the first conveyor line 1. Along the direction of the circulating conveyor line, the adjacent clamp bases 8 can be detachably connected. In this embodiment, the front and rear ends of the clamp base 8 are respectively provided with a connecting groove and a connecting cam. The connecting groove of the clamp base 8 is through in the X-axis direction, and the connecting cam is buckled into or detached from the connecting groove along the X-axis direction to achieve detachable connection. When the connecting cam is buckled into the connecting groove, the first conveyor line 1, the second conveyor line 2, and the third conveyor line 3 are all transported in the Y-axis direction, so that the connection between the connecting cam and the connecting groove is not affected. At the same time, the front and rear adjacent (Y-axis direction) clamp bases 8 can be driven to move, and the first Y-axis moving mechanism 6 and The second Y-axis moving mechanism 7 conveys the fixture base 8 for single conveying, so the connected cam can be directly buckled into or out of the connected groove along the X-axis direction to realize the switching of the fixture base 8 between the first conveyor line 1 and the second conveyor line 2 and the third conveyor line 3. Each fixture base 8 is provided with a mold unit, and each mold unit can clamp a battery module 50. The first locking mechanism 9 and the second locking mechanism 10 of the mold unit can select a clamping arm. The two clamping arms are connected by a spring to keep the battery module 50 clamped to prevent loosening. When the battery module 50 needs to be placed between the two clamping arms, the unlocking mechanism is driven to pull the two clamping arms apart, and the battery module 50 is placed between the two clamping arms. After the unlocking mechanism is closed, the two clamping arms keep the battery module 50 clamped, and the loading of the battery module 50 is completed. Both clamping arms are slidably matched with the fixture base 8 to improve the movement accuracy of the opening and closing actions of the two clamping arms, making the structure more compact. The mold unit in this embodiment is detachable or placed on the mold base, so the jacking structure can drive the mold unit in the corresponding position to rise to the pre-welding position, and perform pre-welding after being fixed by a welding fixture. In this embodiment, the welding template 35 is provided with a welding area and welding fixtures on both sides of the welding area, so the two welding templates 35 can clamp different battery modules 50 at the same time, and the laser welding unit 40 can adjust the position through the welding X-axis moving unit 38 and the welding Z-axis moving unit 39, and weld different battery molds in turn, thereby reducing the welding interval time and improving the welding efficiency. In addition, a rangefinder 46 is also provided to detect the poles and other structures of the battery module 50, through the ranging X-axis moving unit 44. The ranging Y-axis moving unit 45 detects the two battery modules 50. In this embodiment, there are two welding templates 35 and two ranging components, and it is not limited to two welding templates 35 and two ranging components.

[0062] In this embodiment, a second driving mechanism 5 is arranged between the second conveyor line 2 and the third conveyor line 3. The linear moving unit of the second driving mechanism 5 can be a linear module. The linear moving unit moves forward and backward along the Y-axis direction. The second connecting member 42 may include a telescopic member. In this embodiment, the telescopic member can be a telescopic cylinder, a linear module or a double-headed telescopic cylinder. According to the specific situation, a double-headed telescopic cylinder can be arranged to drive the second connecting member 42 to simultaneously drive the second conveyor line 2 and the third conveyor line 3, so that the second connecting member 42 moves left and right along the X-axis direction, thereby realizing telescoping toward the second conveyor line 2 or the third conveyor line 3, so that the left and right ends of the second connecting member 42 can be connected to the connecting groove 41, and the left and right ends of the second connecting member 42 can be provided with driving cams. When the driving cam at the left end of the second connecting member 42 is matched and connected with the connecting groove 41, the linear moving unit is controlled to drive the second connecting member 42 to move along the Y-axis direction. At this time, the driving cam of the second connecting member 42 drives the clamp base 8 on the second conveyor line 2 to move along the Y-axis direction through the connecting groove 41, thereby driving the clamp base 8 on the second conveyor line 2 to move. Similarly, when the driving cam at the right end of the second connecting member 42 is matched and connected with the connecting groove 41, the linear moving unit is controlled to drive the second connecting member 42 to move along the Y-axis direction. At this time, the driving cam of the second connecting member 42 drives the clamp base 8 on the third conveyor line 3 to move along the Y-axis direction through the connecting groove 41, so as to drive the clamp base 8 on the third conveyor line 3 to move. When the clamp base 8 of the second conveyor line 2 and the clamp base 8 of the third conveyor line 3 both need to move forward, the second connecting member 42 and the connecting groove 41 on the clamp base 8 of the second conveyor line 2 and the third conveyor line 3 can be driven by the telescopic cylinder or the linear module. 3, the connecting groove 41 on the clamp base 8 is alternately connected and driven to connect the time of alternating welding on the two welding templates 35, so that the time of conveying and welding is more compact and coordinated, which greatly improves the overall processing efficiency. Finally, the unloading assembly above the second conveyor line 2 and the third conveyor line 3 is used for unloading. The X-axis unloading mechanism 17 and the Z-axis unloading mechanism 18 can prompt the unloading jaw 19 to unload the processed battery cell module 50. Similarly, unlocking mechanisms are correspondingly arranged on both sides of the second conveyor line 2 and the third conveyor line 3 below the unloading assembly to control the opening and closing of the mold unit to realize the transfer of the battery cell module 50.

[0063] In this embodiment, the unlocking member 48 and the fastener 49 are both L-shaped. The unlocking member 48 and the fastener 49 can move mutually along the Y-axis direction, but can abut or engage each other in the X-axis direction. The unlocking telescopic element 47 can be a cylinder, and the fastener 49 is pulled by the unlocking member 48, so that the first locking mechanism 9 and the second locking mechanism 10 are separated from each other. That is, the unlocking member 48 and the fastener 49 are in an inverted structure, but do not affect the relative movement of the unlocking member 48 and the fastener 49 in the Y-axis direction, and only limit the unlocking member 48 to pull the fastener 49 to move in the X-axis direction, so that the mold unit opens and releases the battery module 50.

[0064] Specifically, the lifting unit 36 ​​can select a telescopic structure such as a cylinder or an electric push rod. The telescopic end of the lifting unit 36 ​​is set upward, and the lifting block 37 is connected to the telescopic end of the lifting unit 36. The second conveyor line 2 and the third conveyor line 3 are both provided with corresponding lifting structures. In this embodiment, the corresponding lifting structure is located directly below the welding area of ​​the welding template 35 to ensure that the lifting block 37 drives the battery cell module 50 on the mold unit to the welding fixture for clamping. The lifting structure can also be set to directly drive the mold unit and the battery cell module 50 to rise together to the welding fixture for clamping and positioning. The specific setting is designed according to actual needs.

[0065] Fig.11 The dotted line portion on the left side is an enlarged structural diagram of the second connecting member 42 .

[0066] In this embodiment, the opening and closing drive unit 29 is composed of a double cylinder, and the two telescopic ends of the double cylinder respectively drive the first correction left arm 30 and the second correction left arm to move, that is, the opening and closing drive unit 29 can control the first correction left arm 30 and the second correction left arm to move closer to each other to clamp the battery module 50 on one side, or the opening and closing drive unit 29 controls the first correction left arm 30 and the second correction left arm to move away from each other to release the battery module 50. Specifically, the first correction left arm 30 and the second correction right arm 31 are arranged at an angle on opposite sides, that is, the first correction left arm 30 and the second correction right arm 31 form guide openings at both ends close to the battery module 50, so as to facilitate guiding and clamping the battery module 50. Figure 7 As shown, the guide opening increases from left to right. Accordingly, the first correction moving mechanism 33 can be selected from a linear slider and a cylinder, the first correction moving mechanism 33 can drive the first correction left arm 30 and the second correction right arm 31 to move toward or away from the battery module 50 at the same time, and the second correction moving mechanism 34 can drive the second correction arm 32 to move toward or away from the battery module 50.

[0067] The first positioning lifting unit 23, the first positioning telescopic unit 24 and the first positioning block 25 are arranged directly below the first correction left arm 30 and the second correction right arm 31. The second positioning lifting unit 26, the second positioning telescopic unit 27 and the second positioning block 28 are arranged directly below the second correction arm 32. The first positioning block 25 and the second positioning block 28 are arranged opposite to each other and have the same shape. They are both stepped structures and can also be L-shaped structures. The first positioning lifting unit 23 can adjust the vertical height of the first positioning block 25, and the second positioning lifting unit 26 can adjust the vertical height of the second positioning block 28. The first positioning telescopic unit 24 and the second positioning telescopic unit 27 are used to adjust the positions of the first positioning block 25 and the second positioning block 28 in the X-axis direction, respectively. The first positioning telescopic unit 24 is used to adjust the positioning position of the first positioning block 25 relative to the battery module 50, and the second positioning telescopic unit 27 is used to adjust the positioning position of the second positioning block 28 relative to the battery module 50.
