Description

Technical Field

[0001] The present invention relates to the technical field of battery manufacturing equipment, and in particular to a deviation rectifying device and a bus bar welding integrated machine. Background Art

[0002] Before the battery strings are welded to the bus bar, deviation rectification needs to be carried out to ensure that the positions to be welded (welding head ends) on each column of battery strings are aligned with the final welding station. Furthermore, when the bus bar arrives, the battery strings and the bus bar can be quickly welded together. The welding integrated machines in the prior art cannot carry out deviation rectification on the battery strings, thus affecting the welding accuracy between the battery strings and the bus bar.

[0003] Based on the above problems, it is particularly important to propose a device capable of carrying out deviation rectification on the battery strings.

[0058] The present invention will be further described in detail below through specific embodiments in combination with the accompanying drawings.

[0059] The specific structure is as Figure 1 - Figure 4 shown. In this embodiment, the up and down in Figure 1 are used as up and down, the left and right are used as left and right, the direction perpendicular to the paper surface and into the paper is the front, and the direction perpendicular to the paper surface and out of the paper is the back.

[0060] A deviation rectifying device provided in this embodiment includes: a deviation rectifying mechanism 100 and an extraction mechanism 200 for extracting a battery string; the deviation rectifying mechanism 100 includes a mounting base 110, at least one set of first deviation rectifying driving components 120 and at least two sets of second deviation rectifying driving components 130 provided on the mounting base 110; the extraction mechanism 200 is connected to the mounting base 110; at least one set of first deviation rectifying driving components 120 is in transmission connection with the extraction mechanism 200 and can drive the extraction mechanism 200 to move relative to the mounting base 110 in the left - right direction; at least two sets of second deviation rectifying driving components 130 are in transmission connection with the extraction mechanism 200, and at least two sets of second deviation rectifying driving components 130 cooperate with each other and can drive the extraction mechanism 200 to move relative to the mounting base 110 in the front - back direction and / or rotate on a horizontal plane relative to the mounting base 110. It should be noted here that in this embodiment, the left - right direction of the deviation rectifying device corresponds to the length direction of the product to be deviation - rectified (battery string), and the front - back direction of the deviation rectifying device corresponds to the width direction of the product to be deviation - rectified (battery string).

[0061] The deviation rectifying device provided in this embodiment includes a deviation rectifying mechanism 100 and an extraction mechanism 200. Among them, the deviation rectifying mechanism 100 includes a mounting base 110, at least one set of first deviation rectifying driving components 120 and at least two sets of second deviation rectifying driving components 130. The output ends of the first deviation rectifying driving components 120 and the second deviation rectifying driving components 130 are in transmission connection with the extraction mechanism 200. Thus, under the driving action of the first deviation rectifying driving components 120, the extraction mechanism 200 can move in the left - right direction to adjust the position of the battery string thereon in the left - right direction; under the combined driving action of the second deviation rectifying driving components 130, the extraction mechanism 200 can move in the front - back direction to adjust the position of the battery string thereon in the front - back direction. At the same time, at least two sets of second deviation rectifying driving mechanisms cooperate to drive the extraction mechanism 200 to rotate a certain angle to adjust the angle of the battery string thereon.

[0062] The deviation rectifying device provided in this embodiment can adjust the left - right position, front - back position, and the angle on the horizontal plane of the extraction mechanism 200, and the extraction mechanism 200 synchronously drives the battery string to adjust the left - right position, front - back position, and the angle on the horizontal plane, so that the welding position of the battery string is aligned with the final welding station, thereby ensuring the position accuracy of the battery string. And when the bus bar arrives, it can also quickly weld the battery string and the bus bar, improving the welding efficiency.

[0063] In this embodiment, the extraction mechanism 200 can adopt a mechanical clamping method or a vacuum adsorption method, both of which can meet the requirements for extracting the battery string. Considering that mechanical clamping may cause certain damage to the battery string, the vacuum adsorption method is preferably adopted in this embodiment. Specifically, the extraction mechanism 200 includes a long strip-shaped fixing plate 210 corresponding to the shape of the battery string for easy extraction. A plurality of adsorption components 220, such as suction heads or suction cups, are arranged at intervals on the fixing plate 210. The adsorption component 220 is connected to an external vacuum device through a pipeline. Thus, the adsorption of the battery string can be realized, so that the deviation rectifying mechanism 100 can drive the extraction mechanism 200 to move to adjust the position of the extraction mechanism 200 and the battery string adsorbed thereon.

[0064] It should be noted that the deviation rectifying mechanism 100 in this embodiment includes at least one set of first deviation rectifying driving components 120 and at least two sets of second deviation rectifying driving components 130. When one set of first deviation rectifying driving components 120 is provided, this set of first deviation rectifying driving components 120 can drive the extraction mechanism 200 to move in the left-right direction. When multiple sets of first deviation rectifying driving components 120 are provided, the output ends of the multiple sets of first deviation rectifying driving components 120 are coordinated with the extraction mechanism 200 in the same way (providing the same magnitude and direction of force to the extraction mechanism 200, such as arranged in rows, etc.), and the multiple sets move synchronously. Thus, it can also meet the requirement of driving the extraction mechanism 200 to move in the left-right direction. Similarly, when two sets of second deviation rectifying driving components 130 are provided, when the two sets of second deviation rectifying driving components 130 drive the extraction mechanism 200 in the same direction, the extraction mechanism 200 can move in the front-back direction. When the two sets of second deviation rectifying driving components 130 drive the extraction mechanism 200 in opposite directions, due to the generated torque, the extraction mechanism 200 can rotate a certain angle. Preferably, the two sets of second deviation rectifying driving components 130 are respectively arranged at positions near the left and right ends of the extraction mechanism 200. At this time, since the left-right direction corresponds to the length direction of the product to be deviation rectified (battery string), when the second deviation rectifying driving components 130 at the left and right ends cooperate in driving, they can synchronously drive the left and right ends of the extraction mechanism 200, improving the synchronous accuracy of left-right deviation rectification. And when the second deviation rectifying driving components 130 at the left and right ends cooperate, they can increase the rotational torque, facilitating the adjustment of the angle in the horizontal plane. When multiple sets of second deviation rectifying driving components 130 are provided, the principle is similar to that of the multiple sets of first deviation rectifying driving components 120 above. In addition, the multiple sets of second deviation rectifying driving components 130 are divided into two parts (for example, two rows, where each part can include multiple sets), and the two parts of second deviation rectifying driving components 130 move synchronously. When the two parts of second deviation rectifying driving components 130 drive the extraction mechanism 200 in the same direction, the extraction mechanism 200 moves in the front-back direction. When the two parts of second deviation rectifying driving components 130 drive the extraction mechanism 200 in opposite directions, the extraction mechanism 200 rotates. Preferably, the two parts of second deviation rectifying driving components 130 are respectively arranged at positions near the left and right ends of the extraction mechanism 200. Specifically, reference can be made to the above scheme with two sets, which will not be elaborated here.

[0065] In an alternative technical solution of this embodiment, the deviation rectifying mechanism 100 includes multiple sets of guiding seats 140 respectively used in cooperation with the first deviation rectifying driving components 120 and the second deviation rectifying driving components 130. The guiding seats 140 are fixedly connected to the extraction mechanism 200. The guiding seats 140 are provided with guiding grooves, and guiding components 150 are arranged at the output ends of the first deviation rectifying driving components 120 and the second deviation rectifying driving components 130, and the guiding components 150 are matched with the guiding grooves.

[0066] In the optional technical solution of this embodiment, the guiding component 150 includes an eccentric shaft 151 and a follower 152. The follower 152 is placed at the output end of the eccentric shaft 151, and the input end of the eccentric shaft 151 is used for driving connection with the corresponding first deviation rectifying driving component 120 or the second deviation rectifying driving component 130; the cross-section of the guiding groove is set to the shape of a long hole, and the length dimension of the guiding groove is greater than the outer diameter of the follower 152, and the width dimension of the guiding groove is equal to the outer diameter of the follower 152; the first deviation rectifying driving component 120 can squeeze the side wall in the width direction of the corresponding first guiding groove 141 through the follower 152 in the guiding component 150, and drive the extraction mechanism 200 to move in the left-right direction through the guiding seat 140 used in cooperation with the first deviation rectifying driving component 120; the second deviation rectifying driving component 130 can squeeze the side wall in the width direction of the corresponding second guiding groove 142 through the follower 152 in the guiding component 150, and drive the extraction mechanism 200 to move in the front-back direction or rotate on the horizontal plane through the guiding seat 140 used in cooperation with the second deviation rectifying driving component 130.

[0067] Specifically, both the first deviation rectifying driving component 120 and the second deviation rectifying driving component 130 include a driving motor and the guiding component 150, where the guiding component 150 includes an eccentric shaft 151 and a follower 152. The output shaft of the driving motor (actually referring to the driving motor rotating shaft) is in driving connection with the eccentric shaft 151, and the follower 152 is in driving connection with the eccentric shaft 151. Thus, the driving motor can drive the eccentric shaft 151 to rotate, and the eccentric shaft 151 can drive the follower 152 to sway. Further, the deviation rectifying mechanism 100 further includes a guiding seat 140. The guiding seat 140 is fixedly installed on the extraction mechanism 200 (the guiding seat 140 is fixedly connected with the fixing plate 210), and a guiding groove is formed on the guiding seat 140, and the follower 152 is clamped in the corresponding guiding groove.

[0068] Further, the guiding groove adopts the shape of a long hole (or a rounded rectangle), and the length dimension of the guiding groove is greater than the outer diameter of the follower 152. In order to improve the precision and reduce the impact, it is necessary to design the width dimension of the guiding groove to be equal to the outer diameter of the follower 152 and meet certain tolerance requirements. In this way, when the driving motor drives the eccentric shaft 151 to rotate, the eccentric shaft 151 drives the follower 152 to sway, and the follower 152 can squeeze the side wall in the width direction of the guiding groove, and the guiding seat 140 transmits the power to the extraction mechanism 200 to drive the extraction mechanism 200 to move; in addition, since the length dimension of the guiding groove is greater than the outer diameter of the follower 152, the follower 152 has a certain floating amount in the length direction of the guiding groove, and when the driving motor drives the eccentric shaft 151 and the follower 152 to rotate, it can ensure that the length direction of the guiding groove does not limit the movement of the follower 152.

[0069] It should be noted that the first deviation rectifying drive assembly 120 can drive the extraction mechanism 200 to move in the left - right direction. Thus, the width direction of the first guide groove 141 used in cooperation with the first deviation rectifying drive assembly 120 is along the left - right direction, and the length direction is along the front - back direction. In this way, the first deviation rectifying drive assembly 120 can drive the guide seat 140 to move in the left - right direction through the eccentric shaft 151 and the follower 152, so as to adjust the left - right position of the extraction mechanism 200. Similarly, the second deviation rectifying drive assembly 130 can drive the extraction mechanism 200 to move in the front - back direction. Thus, the width direction of the second guide groove 142 used in cooperation with the second deviation rectifying drive assembly 130 is along the front - back direction, and the length direction is along the left - right direction. In this way, two groups or two parts (each part includes multiple groups) of the second deviation rectifying drive assembly 130 can drive the guide seat 140 to move in the front - back direction or rotate on the horizontal plane through the eccentric shaft 151 and the follower 152. When the acting force directions of the two groups or two parts of the second deviation rectifying drive assembly 130 are the same, the extraction mechanism 200 is subjected to the same - direction force and moves in the front - back direction to adjust the front - back position of the extraction mechanism 200. When the acting force directions of the two groups or two parts of the second deviation rectifying drive assembly 130 are opposite, the extraction mechanism 200 is subjected to the reverse force and the extraction mechanism 200 rotates to adjust the angle of the extraction mechanism 200 on the horizontal plane. It should be noted that the two groups or two parts of the second deviation rectifying drive assembly 130 are arranged at intervals. Thus, when the acting force is in the reverse direction, a torque that causes the extraction mechanism 200 to rotate is generated to drive the extraction mechanism 200 to rotate.

[0070] In an alternative technical solution of this embodiment, the extraction mechanism 200 and the mounting seat 110 are connected through a linkage assembly 160; the linkage assembly 160 includes a first guiding member 161, a second guiding member 162, and a rotation - connecting member 163. The first guiding member 161 is fixedly connected to the mounting seat 110, and the second guiding member 162 is slidably connected to the first guiding member 161; the first guiding member 161 is arranged along the front - back direction, and the second guiding member 162 is arranged along the left - right direction, or the first guiding member 161 is arranged along the left - right direction, and the second guiding member 162 is arranged along the front - back direction; a sliding seat is arranged between the second guiding member 162 and the rotation - connecting member 163. The sliding seat is slidably connected to the second guiding member 162. The first end of the rotation - connecting member 163 is connected to the sliding seat, and the second end is connected to the extraction mechanism 200.

[0071] It should be noted that after the extraction mechanism 200 is subjected to an acting force, it needs to move in the left - right direction, move in the front - back direction, and also change the angle on the horizontal plane. Thus, the deviation rectifying mechanism 100 in this embodiment further includes a linkage assembly 160. The linkage assembly 160 is connected between the extraction mechanism 200 and the mounting seat 110 to provide connection and guiding functions for the position adjustment of the extraction mechanism 200.

[0072] Specifically, the linkage component 160 includes a first guiding member 161 (preferably a guide rail), a second guiding member 162 (preferably a guide rail), and a rotating connection member 163. Among them, the first guiding member 161 is disposed at the bottom of the mounting base 110. The second guiding member 162 is slidably connected to the first guiding member 161 through a slider. The rotating connection member 163 is slidably connected to the second guiding member 162 through a sliding seat. Specifically, the rotating connection member 163 includes a rotating shaft and a bearing seat. The bearing seat is fixedly connected to the fixing plate 210 of the extraction mechanism 200. One end of the rotating shaft is rotatably connected to the bearing seat, and the other end is rotatably connected to the sliding seat. The sliding seat is slidably connected to the second guiding member 162, so that the extraction mechanism 200 connected to the rotating connection member 163 can not only move in the front-back direction relative to the second guiding member 162, but also rotate around the rotating shaft. Moreover, the first guiding member 161 is disposed in the left-right direction or the front-back direction, the second guiding member 162 is disposed in the front-back direction or the left-right direction, and the first guiding member 161 and the second guiding member 162 are arranged perpendicular to each other. Based on this, when the extraction mechanism 200 is subjected to a force in the left-right direction, it can move along the guiding member disposed in the left-right direction. When the extraction mechanism 200 is subjected to a force in the front-back direction, it can move along the guiding member disposed in the front-back direction. When subjected to a torque, it can rotate a certain angle on the horizontal plane through the rotating connection member 163. Thus, through the coordinated use of the first guiding member 161, the second guiding member 162, and the rotating connection member 163, it can provide guidance for the extraction mechanism 200 in the left-right direction, the front-back direction, and the angle switching, so as to ensure that the movement position of the extraction mechanism 200 is more stable and accurate.

[0073] Preferably in this embodiment, referring to Figure 1 、 2 , two sets of linkage components 160 are connected between the extraction mechanism 200 and the mounting base 110. Two sets or two parts (each part includes multiple groups) of the second deviation correction driving components 130 are respectively located on the left and right sides of the first deviation correction driving component 120. The two sets of linkage components 160 are located on the left and right sides of the guiding seat 140 that cooperates with the first deviation correction driving component 120. And the two sets or two parts (each part includes multiple groups) of guiding seats 140 that cooperate with the two sets or two parts of the second deviation correction driving components 130 are located on the left and right sides of the two sets of linkage components 160. Thus, when the extraction mechanism 200 is subjected to a force or a torque, it can move or rotate stably and accurately, and further realize the deviation correction process of the extraction mechanism 200 and the battery string thereon.

[0074] In an alternative technical solution of this embodiment, the deviation rectifying device includes a lifting mechanism 300, and the lifting mechanism 300 includes a lifting driving member 310, a lifting guiding member 320, and a lifting connecting member 330; the lifting connecting member 330 is slidably connected to the lifting guiding member 320, the lifting connecting member 330 is drivingly connected to the output end of the lifting driving member 310, and the mounting seat 110 is connected to the lifting connecting member 330; the lifting driving member 310 can drive the lifting connecting member 330 and the deviation rectifying mechanism 100 to move in the up and down direction relative to the lifting guiding member 320.

[0075] Preferably, the lifting driving member 310 can adopt a combination of a motor and a screw rod, or can also adopt a cylinder, etc., the lifting guiding member 320 adopts a guide rail, the lifting connecting member 330 can adopt a plate-like structure, and the mounting seat 110 in the deviation rectifying mechanism 100 is fixedly connected to the lifting connecting member 330. Thus, the lifting driving member 310 can drive the lifting connecting member 330, the deviation rectifying mechanism 100, and the extraction mechanism 200 to move up and down, so as to facilitate the extraction process of the battery string. It should be noted here that a set of deviation rectifying mechanism 100 and extraction mechanism 200 can be provided at the bottom of the lifting connecting member 330, and of course, multiple sets of deviation rectifying mechanisms 100 and extraction mechanisms 200 arranged at intervals can also be provided to facilitate deviation rectification of multiple sets of battery strings at one time.

[0076] In an alternative technical solution of this embodiment, the deviation rectifying device includes a translation mechanism 400, and the translation mechanism 400 includes a translation driving member 410, a translation guiding member 420, and a translation connecting member 430; the translation guiding member 420 is connected to the lifting connecting member 330, the translation connecting member 430 is slidably connected to the translation guiding member 420, the translation connecting member 430 is connected to the output end of the translation driving member 410, and the mounting seat 110 in the deviation rectifying mechanism 100 is connected to the translation connecting member 430; the translation driving member 410 can drive the translation connecting member 430 and the deviation rectifying mechanism 100 to move in the front and back direction relative to the translation guiding member 420 to adjust the front and back position of the deviation rectifying mechanism 100.

[0077] In an alternative technical solution of this embodiment, a limiting structure 331 for restricting the moving range of the translation connecting member 430 is provided on the lifting connecting member 330.

[0078] In the optional technical solution of this embodiment, the correction device includes multiple groups of correction mechanisms 100, multiple groups of extraction mechanisms 200, multiple groups of translation connection components 430, multiple groups of translation drive components 410 and one or more groups of translation guide components 420; one or more groups of translation guide components 420 are connected to the lifting connection components 330, multiple groups of translation connection components 430 are correspondingly slidably connected to one or more groups of translation guide components 420, the output ends of multiple groups of translation drive components 410 are respectively connected to multiple groups of translation connection components 430, the mounting seats 110 in multiple groups of correction mechanisms 100 are respectively connected to multiple groups of translation connection components 430, and multiple groups of extraction mechanisms 200 are respectively connected to multiple groups of correction mechanisms 100; multiple groups of translation drive components 410 can respectively drive multiple groups of correction mechanisms 100 to move in the front and rear directions relative to one or more groups of translation guide components 420 to adjust the front and rear distance between two adjacent groups of correction mechanisms 100 and two adjacent groups of extraction mechanisms 200.

[0079] Taking into account that the battery string replacement requires adjustment of the position or spacing of the battery strings in the front-to-back direction (multiple groups of battery strings are arranged along the front-to-back direction, and when the battery strings are replaced, the front-to-back spacing between adjacent battery strings needs to be adjusted), the extraction mechanism 200 and the correction mechanism 100 need to be able to move in the front-to-back direction (multiple groups of battery strings are arranged along the front-to-back direction). Therefore, a translation mechanism 400 is added in this embodiment.

[0080] Specifically, the translation mechanism 400 includes a translation drive component 410, a translation guide component 420 and a translation connecting component 430, wherein the translation drive component 410 adopts a combination of a motor and a screw rod, and can also adopt a cylinder (preferably), and the translation guide component 420 is preferably a guide rail, which is arranged along the front and back direction, and the mounting seat 110 in the correction mechanism 100 is connected to the translation connecting component 430. Thus, the translation drive component 410 can drive the translation connecting component 430 together with the correction mechanism 100 and the extraction mechanism 200 to move along the translation guide component 420, thereby facilitating the adjustment of the distance between two adjacent groups of correction mechanisms 100 and the extraction mechanisms 200 connected thereto, so as to facilitate battery replacement.

[0081] When there is one set each of the deviation rectifying mechanism 100 and the extraction mechanism 200, there is also one set of the translation mechanism 400, that is, it includes one set of translation connection members 430, one set of translation driving members 410 and one set of translation guiding members 420. Thus, the translation driving member 410 can drive the translation connection member 430, the deviation rectifying mechanism 100 and the extraction mechanism 200 to move synchronously in the front-back direction to adjust the front-back position of the extraction mechanism 200 and the battery string thereon. When the deviation rectifying mechanism 100 and the extraction mechanism 200 are provided in multiple sets, multiple sets of translation connection members 430 and multiple sets of translation driving members 410 are required, and the translation guiding members 420 can be provided in one set or multiple sets. Specifically, when one set of translation guiding members 420 is provided, multiple sets of translation connection members 430 are all slidably connected to this set of translation guiding members 420. Under the driving action of multiple sets of translation driving members 410, multiple sets of deviation rectifying mechanisms 100 and multiple sets of extraction mechanisms 200 can all move in the front-back direction along the corresponding translation connection members 430, so as to adjust the distance between adjacent two sets of extraction mechanisms 200, which is convenient for battery string type replacement; when multiple sets of translation guiding members 420 are provided, they correspond one by one to multiple sets of translation connection members 430. Under the driving action of multiple sets of translation driving members 410, multiple sets of deviation rectifying mechanisms 100 and multiple sets of extraction mechanisms 200 can all move in the front-back direction along the corresponding translation connection members to adjust the front-back position between adjacent two sets of extraction mechanisms 200, thus facilitating the replacement of the battery string.

[0082] Further, a limiting structure 331 (positioning bar) is provided on the lifting connection member 330. Correspondingly, a positioning groove is opened on the translation connection member 430, and the positioning bar and the positioning groove are used in cooperation. When the translation connection member 430 moves in the front-back direction and the positioning bar reaches the limit position of the positioning groove, it is restricted, so that the translation connection member 430 cannot move continuously. Thus, the adjustment distance of the deviation rectifying mechanism 100 and the extraction mechanism 200 in the front-back direction is limited, effectively preventing phenomena such as adjacent extraction mechanisms 200 contacting each other or the translation connection member 430 disengaging from the translation guiding member 420 due to mistakes, and improving the safety and stability of equipment use. In addition, the limiting structure 331 can also be provided on the front and rear sides of the translation connection member 430. When the translation connection member 430 moves back and forth and touches the limiting structure 331 on the front side or the rear side, it stops moving. Thus, the adjustment distance of the deviation rectifying mechanism 100 and the extraction mechanism 200 in the front-back direction is limited, effectively preventing phenomena such as adjacent extraction mechanisms 200 contacting each other or the translation connection member 430 disengaging from the translation guiding member 420 due to mistakes, and improving the safety and stability of equipment use.

[0083] In an optional technical solution of this embodiment, the deviation correction device includes a detection mechanism 500 for detecting the position to be welded; the detection mechanism 500 includes a detection component 530 for detecting whether the welding strip head reaches the welding station.

[0084] In this embodiment, a detection mechanism 500 is also added, which can detect whether the battery string welding head has reached the welding station through the detection mechanism 500, so as to correct the battery string. Specifically, the correction mechanism 100 includes a detection component 530, which uses a CCD camera or a position sensor, preferably a CCD camera. The CCD camera is connected to the control device of the equipment, and other actuators are also connected to the control device. Therefore, when the CCD camera detects that the welding head has not reached the welding station, it transmits the situation to the control device in the form of a signal. The control device analyzes and judges the situation and issues an instruction to the actuator to control the correction mechanism 100 to adjust the position of the extraction mechanism 200 and the battery string thereon, so as to improve the position accuracy of the battery string, thereby improving the welding accuracy between the battery string and the busbar.

[0085] Furthermore, the detection mechanism 500 also includes a detection drive component 510 and a detection guide component 520, wherein the detection drive component 510 can be a combination of a motor and a screw rod, or a cylinder, etc., and the detection guide component 520 is arranged along the left and right directions, preferably a guide rail. Thus, the detection component 530 moves along the detection guide component 520 under the driving action of the detection drive component 510 to adjust the left and right position of the detection component 530 to facilitate position detection of the battery string welding head.

[0086] Furthermore, limit members are provided at both ends of the detection guide member 520 to limit the movement range of the detection member 530 .

[0087] The working principle of the deviation correction device provided in this embodiment is as follows:

[0088] When the support base carrying the battery string is in place and calibrated, the position of the battery string on the support base is photographed by a CCD camera, and the control device calculates the coordinate difference between the position of the battery string and the preset position (the final welding station), and feeds back the correction distance to the correction mechanism 100; and controls the lifting mechanism 300 to start, driving the extraction mechanism 200 to descend to extract the battery string, and then rise, and then the first correction drive component 120 and / or the second correction drive component 130 are started to drive the extraction mechanism 200 and the battery string thereon to move in the left and right directions and the front and back directions to adjust the position, and can also drive the extraction mechanism 200 to rotate a certain angle in the horizontal plane, so that the welding head of the battery string is finally opposite to the welding station, so as to improve the welding accuracy between the battery string and the bus bar.

[0089] A bus bar welding all-in-one machine provided in this embodiment includes the above-mentioned deviation rectifying device. Therefore, the technical advantages and effects achieved by this bus bar welding all-in-one machine include those achieved by the above-mentioned deviation rectifying device, which will not be elaborated here.
