[0031] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0032] See also Figure 1 and Figure 2 , the positioning device provided in the embodiment of the present application is now described. The positioning device provided in the embodiment of the present application includes a mounting frame 1, a positioning mechanism and a lifting assembly 2. The mounting frame 1 is provided with a clamping position 11 for positioning the workpiece. The positioning mechanism is arranged on the periphery of the clamping position 11, and the positioning mechanism is used to position the workpiece at the clamping position 11 in the horizontal direction. A first workstation is provided in the vertical direction between the positioning mechanism and an external picking device for picking up the workpiece. The lifting assembly 2 is arranged at the clamping position 11 and can move in the vertical direction. The lifting assembly 2 is used to carry the workpiece at the first workstation.

[0033] The workpiece in the embodiment of the present application may be a battery to be processed, or may be other workpiece to be welded.

[0034] The positioning mechanism may be a plurality of positioning posts arranged on the edge of the clamping position 11 of the mounting frame 1 , and the workpiece abuts against the positioning posts to achieve positioning of the workpiece.

[0035] The jacking assembly 2 may include a jacking plate, a first jacking drive, and a second jacking drive. The jacking plate is mounted on the mounting frame 1 and positioned at the clamping position 11. The first and second jacking drives are positioned on opposite sides of the mounting frame 1. The first and second jacking drives 21 and 21 are respectively connected to the sides of the jacking plate to drive the jacking plate to move vertically. The first and second jacking drives 21 and 21 may be electric cylinders, pneumatic cylinders, or linear motors.

[0036] The lifting assembly 2 of the positioning device of the embodiment of the present application moves vertically to the first station. The external pickup device places the battery to be processed onto the lifting assembly 2. The lifting assembly 2 then moves vertically downward to between the positioning mechanisms, which then position the battery to be processed. The first station is vertically located between the positioning mechanism and the external pickup device used to pick up the workpiece. When the external pickup device releases the battery to be processed, it will not spatially interfere with the positioning mechanism. This prevents the external pickup device and the positioning mechanism from colliding due to spatial interference, thereby reducing the loss rate of the positioning device.

[0037] Preferably, a through hole is provided at the clamping position 11, and the jacking assembly 2 includes a jacking drive 21 and a lifting platform 22, the lifting platform 22 is used to carry the workpiece, the jacking drive 21 is located below the mounting frame 1, and the jacking drive 21 is transmission-connected to the lifting platform 22 to drive the lifting platform 22 to move in the vertical direction in the through hole.

[0038] The lifting drive 21 can be a pneumatic cylinder, electric cylinder, or linear motor. The drive shaft of the lifting drive 21 is connected to the center of the lifting platform 22 to prevent the center of gravity of the lifting platform 22 from shifting. The lifting drive 21 is positioned below the mounting frame 1 to improve space utilization. A through hole provided at the clamping position 11 facilitates the lowering of the lifting platform 22 below the mounting frame 1, allowing the lifting drive 21 to adjust the lifting height of the lifting platform 22 and prevent interference between the workpiece and the welding device.

[0039] Preferably, see Figure 2 The lifting drive component 21 includes a translation drive part 211, a sliding part 212, and a lifting part 213. The translation drive part 211 is transmission-connected to the sliding part 212 to drive the sliding part 212 to move horizontally. A lifting inclined surface 2121 is provided on the sliding part 212. The lifting part 213 slides on the lifting inclined surface 2121 on the sliding part 212, and the lifting part 213 is connected to the lifting platform 22.

[0040] When the sliding portion 212 moves horizontally, the lifting portion 213 can slide on the lifting inclined surface 2121 of the sliding portion 212 in the inclined direction of the lifting inclined surface 2121, thereby achieving the vertical lifting of the lifting platform 22. In this embodiment of the application, the driving direction of the translation drive portion 211 is different from the moving direction of the lifting platform 22, which can save space for the lifting drive member 21 and make the lifting drive member 21 suitable for smaller positioning devices.

[0041] The translation driving unit 211 may specifically be a pneumatic cylinder, an electric cylinder or a linear motor.

[0042] The lifting drive member 21 may further include a guide limit portion, which is connected to the lifting platform 22 and the mounting frame 1 respectively, so that the lifting platform 22 moves in the through hole at the clamping position 11 along the vertical direction.

[0043] The guide limiting portion can be a guide rod or a linear bearing.

[0044] The lifting platform 22 includes a first bearing sub-section 221, an elastic sub-section 222 and a second bearing sub-section 223. The first bearing sub-section 221 is used to bear the workpiece, the second bearing sub-section 223 is connected to the lifting drive component, and the elastic sub-section 222 is arranged between the first bearing sub-section 221 and the second bearing sub-section 223.

[0045] The elastic secondary portion 222 may be made of elastic silicone or a spring. The elastic secondary portion 222 can prevent the workpiece from falling to the first bearing secondary portion 221 due to gravity and causing damage to the workpiece, thereby reducing the damage rate of the workpiece.

[0046] The second secondary bearing portion 223 may be connected to the lifting portion 213 of the lifting driving member 21 .

[0047] The positioning mechanism includes a first positioning component 3 and a second positioning component 4. The first positioning component 3 is arranged at the periphery of the clamping position 11 along the first direction, and the first positioning component 3 is used to position the workpiece along the first direction. The second positioning component 4 is arranged at the periphery of the clamping position 11 along the second direction, and the second positioning component 4 is used to position the workpiece along the second direction. The first direction is perpendicular to the second direction.

[0048] The first direction and the second direction are both horizontal directions. The first positioning component 3 and the second positioning component 4 respectively position the workpiece from two horizontal directions, thereby improving the welding accuracy of the workpiece and improving the product yield.

[0049] The first positioning assembly 3 may include a first pushing member and a second pushing member, which are relatively arranged at the periphery of the clamping position 11. The first pushing member and the second pushing member approach each other along the first direction to push two opposite sides of the workpiece, thereby positioning the workpiece along the horizontal direction.

[0050] The first pusher may include a first horizontal driving portion and a first pushing portion, wherein the first horizontal driving portion is in transmission connection with the first pushing portion to drive the first pushing portion to move in the first direction. The first horizontal driving portion may be a pneumatic cylinder, an electric cylinder, or a linear motor, and the second pusher may have the same structure as the first pusher.

[0051] The second positioning component 4 can adopt the same structure as the first positioning component 3 .

[0052] Preferably, see Figure 1 and Figure 3 The first positioning assembly 3 includes a first driving member 31 and two first positioning members 32 arranged relatively along the first direction on the mounting frame 1. The first driving member 31 is transmission-connected to one of the first positioning members 32 to drive one of the first positioning members 32 to move along the first direction to approach or move away from the other first positioning member 32.

[0053] Of the two first positioning members 32 , the one not connected to the first driving member 31 is a reference member for positioning in the first direction, and the reference member can ensure consistency in multiple positioning operations.

[0054] The first driving member 31 drives one of the first positioning members 32 to approach the other first positioning member 32 along the first direction to position the workpiece; the first driving member 31 drives one of the first positioning members 32 to move away from the other first positioning member 32 along the first direction to release the workpiece.

[0055] The second positioning component 4 can adopt the same structure as the first positioning component 3 .

[0056] The first positioning member 32 includes a first positioning portion 321 and a first elastic follower portion 322. The first elastic follower portion 322 is slidably arranged along the second direction on the side of the first positioning portion 321 close to the workpiece. The first driving member 31 is transmission-connected to the first positioning portion 321 of one of the first positioning members 32 to drive one of the first positioning members 32 to move along the first direction to approach or move away from the other first positioning member 32.

[0057] When the first positioning assembly 3 positions the workpiece along the first direction and the second positioning assembly 4 positions the workpiece along the second direction, the stationary first positioning assembly 3 will wear the side of the moving workpiece, resulting in an increased damage rate of the workpiece and affecting product quality.

[0058] When the second positioning assembly 4 positions the workpiece along the second direction, the first elastic follower 322 in contact with the side surface of the workpiece can slide along the second direction with the workpiece to prevent the first positioning member 32 from wearing the side surface of the workpiece.

[0059] The first elastic follower 322 may be a deformable plate made of an elastic material. After the first elastic follower 322 is no longer in contact with the workpiece, the first elastic follower 322 may be restored to its original position by deforming.

[0060] The first elastic follower portion 322 includes a contact sub-portion 3221 and an elastic reset sub-portion 3222. The contact sub-portion 3221 is slidably arranged along the second direction on the side of the first positioning portion 321 close to the workpiece. The elastic reset sub-portion 3222 is arranged at the end of the sliding path of the contact sub-portion 3221. The elastic reset sub-portion 3222 is connected to the first positioning portion 321 and the contact sub-portion 3221.

[0061] The abutment sub-portion 3221 is a slidable plate that contacts the workpiece. After the first positioning assembly 3 positions the workpiece in a first direction, the second positioning assembly 4 then positions the workpiece in a second direction. The abutment sub-portion 3221 moves with the workpiece in the second direction, compressing the elastic return sub-portion 3222. After the workpiece is positioned, machining is performed. After machining is complete, the second positioning assembly 4 resets to release the workpiece, and the elastic return sub-portion 3222 recovers its deformation, returning the abutment sub-portion 3221 to its original position.

[0062] The first positioning member 32 further includes a guide portion, which is mounted on the first positioning portion 321 and connected to the first elastic follower portion 322 to guide the first elastic follower portion 322 to slide along the second direction.

[0063] The guide portion includes a guide rail and a slider. The guide rail is mounted on the first positioning portion 321 . The slider is slidably mounted on the guide rail. The abutting secondary portion 3221 of the first elastic follower portion 322 is connected to the slider.

[0064] The guide portion can prevent the first elastic follower 322 from deviating from the second direction when sliding.

[0065] An embodiment of the present application also provides a laser processing device, including the above-mentioned positioning device.

[0066] Since the laser processing equipment of the embodiment of the present application includes the positioning device in any of the above embodiments, it has the beneficial effects brought by the positioning device in any of the above embodiments, which will not be repeated here.

[0067] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
