[0027] Please refer to Figure 4 , the positioning assembly 30 comprises a bearing plate 31, a material carrying member 32, a plurality of clamping driving members 33 and a plurality of clamping members 34. The bearing plate 31 is drivingly connected with the material moving driving member 20, the material carrying member 32 is arranged on the bearing plate 31, the material carrying member 32 is provided with a plurality of first half grooves 321 on both sides along the X-axis direction, the plurality of clamping driving members 33 are connected with the bearing plate 31 and arranged on both sides of the material carrying member 32 along the X-axis direction, the plurality of clamping members 34 are arranged on both sides of the material carrying member 32 along the X-axis direction, and the plurality of clamping members 34 are drivingly connected with the corresponding clamping driving members 33. Each clamping member 34 is provided with a second half groove 341 corresponding to the first half groove 321, and the first half groove 321 and the second half groove 341 are used to cooperatively accommodate the first workpiece 200, and the material carrying member 32 is used to carry the second workpiece 300.

[0028] The bearing plate 31 is a plate structure to provide stable support for the load piece 32, the plurality of clamping driving pieces 33 and the like. The load piece 32 can be a block structure to support the second workpiece 300, the clamping driving piece 33 can be a telescopic motor or the like, and the number of the clamping driving piece 33 can be two, four or the like, which are arranged on both sides of the load piece 32.

The first half slot 321 and the second half slot 341 are both parts of a circular through hole, and when the first half slot 321 and the corresponding second half slot 341 are combined, a complete circular through hole is formed to position the first workpiece 200. The number and position of the first half slot 321 and the second half slot 341 correspond to the number and position of the first workpiece 200 to be actually installed on the second workpiece 300, and the actual situation is specific, which is not limited here.

[0029] It can be understood that the positioning accuracy of the first workpiece 200 is related to the size of the circular through hole for accommodating the first workpiece 200, that is, the larger the tolerance between the size of the circular through hole for accommodating the first workpiece 200 and the size of the first workpiece 200, the lower the positioning accuracy, but it is easy to install and disassemble the first workpiece 200; the smaller the tolerance between the size of the circular through hole for accommodating the first workpiece 200 and the size of the first workpiece 200, the higher the positioning accuracy, but it is difficult to install and disassemble the first workpiece 200. In the embodiment, the circular through hole for positioning the first workpiece 200 is divided into the first half slot 321 and the second half slot 341, before the first workpiece 200 is installed, the clamping driving piece 33 drives the clamping piece 34 to approach the load piece 32, and the second half slot 341 approaches the first half slot 321 but does not completely connect, at this time, it is convenient to install the first workpiece 200. After the first workpiece 200 is installed, the clamping driving piece 33 drives the clamping piece 34 to drive the clamping piece 34 to abut the load piece 32, so that the second half slot 341 and the first half slot 321 completely connect, at this time, the clamping piece 34 cooperates with the load piece 32 to clamp the first workpiece 200 through the first half slot 321 and the second half slot 341, and the positioning accuracy of the first workpiece 200 is high. When disassembling, the clamping driving piece 33 drives the clamping piece 34 away from the load piece 32, the positioning assembly 30 has high positioning accuracy for the first workpiece 200, and it is convenient to install and disassemble the first workpiece 200.

[0030] The welding assembly 40 is arranged in the processing bin 12, and includes a welding machine 41 arranged above the material moving driving member 20 along the Z-axis direction, which is used for welding the first workpiece 200 and the second workpiece 300. The welding machine 41 can be a laser welding machine or the like. When the material moving driving member 20 drives the positioning assembly 30 to move to the processing bin 12 and makes the welding machine 41 correspond to the connecting position of the first workpiece 200 and the second workpiece 300, the welding machine 41 can weld the first workpiece 200 and the second workpiece 300. After the welding is completed, the material moving driving member 20 can move the positioning assembly 30, the first workpiece 200 and the second workpiece 300 out of the processing bin 12. It can be understood that the welding machine 41 can be connected with an adjusting structure to adjust the output position of the welding machine 41 and then weld the first workpiece 200 and the second workpiece 300.

[0031] The welding device 100 provided by the embodiment of the present application can accurately position the first workpiece 200. When the first workpiece 200 is positioned, the clamping driving member 33 drives the clamping member 34 to approach the material carrying member 32, so that the second half groove 341 on the clamping member 34 approaches the corresponding first half groove 321. At this time, the clamping member 34 does not contact the material carrying member 32, the size of the groove structure combined by the first half groove 321 and the second half groove 341 is greater than the size of the first workpiece 200, and the first workpiece 200 is conveniently placed. After the first workpiece 200 is placed, the clamping driving member 33 drives the clamping member 34 to abut against the material carrying member 32, the first half groove 321 and the second half groove 341 are combined into a complete groove structure, and the positioning accuracy of the first workpiece 200 is improved. Then, the second workpiece 300 is placed on the material carrying member 32 and is clamped with the first workpiece 200. The material moving driving member 20 drives the positioning assembly 30, the first workpiece 200 and the second workpiece 300 to move to the processing bin 12, and makes the connecting position of the first workpiece 200 and the second workpiece 300 correspond to the welding machine 41, and the welding machine 41 automatically welds. After the welding is completed, the material moving driving member 20 drives the positioning assembly 30, the first workpiece 200 and the second workpiece 300 to move out of the processing bin 12, and the clamping driving member 33 drives the clamping member 34 to move away from the material carrying member 32, so that the first workpiece 200 and the second workpiece 300 after the welding are conveniently taken out. The welding device 100 provided by the embodiment of the present application has high positioning accuracy for the first workpiece 200, can automatically weld through the welding machine 41, has high welding accuracy, and has high work efficiency.

[0032] In some embodiments, please refer to Figure 1 , Figure 2 and Figure 3The welding assembly 40 further comprises a transverse driving member 42 extending along the X-axis direction, the transverse driving member 42 is drivingly connected with the welding machine 41, and the transverse driving member 42 is configured to drive the welding machine 41 to move along the X-axis direction. The transverse driving member 42 can be a linear module or other driving member. By arranging the transverse driving member 42, the welding machine 41 can be driven to freely move along the X-axis direction. It can be understood that the material moving driving member 20 can drive the first workpiece 200 and the second workpiece 300 to freely move along the Y-axis direction by the positioning assembly 30. By cooperation of the material moving driving member 20 and the transverse driving member 42, the welding machine 41 can weld all the positions to be welded of the first workpiece 200 and the second workpiece 300 in the X-Y plane.

[0033] In some embodiments, referring to Figure 2 and Figure 3 The welding assembly 40 further comprises a longitudinal driving member 43 drivingly connected with the transverse driving member 42, and the longitudinal driving member 43 is further drivingly connected with the welding machine 41. The longitudinal driving member 43 is configured to drive the welding machine 41 to move along the Z-axis direction. The longitudinal driving member 43 can be a lifting cylinder, a lifting motor or other driving member. The longitudinal driving member 43 drives the welding machine 41 to move along the Z-axis direction, so that the distance between the welding machine 41 and the workpiece can be more accurately controlled. During the welding process, the distance between the welding machine 41 and the workpiece has a great influence on the welding quality. If the distance is too close, the welding machine 41 can be damaged or the first workpiece 200 and the second workpiece 300 can be excessively melted. If the distance is too far, the welding can not be firm, and the welding can be loose. By accurate control of the longitudinal driving member 43, the welding machine 41 can always be kept at the optimal welding distance, so as to improve the welding quality and reduce the welding defects. During the production process, for different welding tasks, the welding machine 41 can quickly adjust the position by the transverse driving member 42 and the longitudinal driving member 43, so that the time for re-adjusting the machine or replacing the positioning assembly 30 is reduced, and the production efficiency is improved.

[0034] In some embodiments, referring to Figure 1 , Figure 2 and Figure 3The welding assembly 40 further comprises a detector 44 drivingly connected with the longitudinal driving member 43, the detector 44 being configured to detect the first workpiece 200 and the second workpiece 300. The detector 44 can be a camera, a CCD (Charge-Coupled Device) camera, etc. When the first workpiece 200 and the second workpiece 300 move to below the transverse driving member 42, the transverse driving member 42 can drive the detector 44 to acquire images of the first workpiece 200 and the second workpiece 300, and send the images to a processor, a computer, etc. to compare the acquired images with standard position images to determine whether the assembly of the first workpiece 200 and the second workpiece 300 is qualified. If yes, welding is performed. If not, the first workpiece 200 and the second workpiece 300 are moved out of the processing chamber 12 by the material moving driving member 20, and an operator checks. In the embodiment, the machine table 10 can further be connected with an alarm 123, etc. The alarm 123 is electrically connected with the detector 44. When the detector 44 detects that the positions of the first workpiece 200 and the second workpiece 300 are incorrect, the alarm 123 can send a signal to remind the operator to check. The detector 44 can also detect the first workpiece 200 and the second workpiece 300 after welding. The detector 44 acquires images of the first workpiece 200 and the second workpiece 300 after welding, and compares the images with standard welding images. If not qualified, the alarm 123 sends a signal to remind the operator to check.

[0035] In some embodiments, referring to Figure 2 and Figure 3 Each clamping member 34 is provided with a limiting protrusion 342 arranged towards the material carrying member 32. The material carrying member 32 is provided with a limiting recess 322 matched with the limiting protrusion 342. The limiting protrusion 342 is configured to be inserted into the corresponding limiting recess 322 to limit the clamping member 34. The limiting protrusion 342 can be arranged on both sides of the clamping member 34 along the Y-axis direction, and has a strip-shaped or plate-shaped structure. The limiting recess 322 can be correspondingly arranged on both sides of the material carrying member 32 along the Y-axis direction, and has a structure matched with the limiting protrusion 342. When the clamping driving member 33 drives the clamping member 34 to move towards the material carrying member 32, the limiting protrusion 342 slides along the limiting recess 322 to limit the clamping member 34 in the Z-axis direction.

[0036] In some embodiments, referring to Figure 3 and Figure 4The positioning assembly 30 further comprises a pressing member 35, which is arranged on the side of the second workpiece 300 away from the carrier 32, and is used to press the second workpiece 300. The pressing member 35 can be a plate structure or a special-shaped mechanism. The second workpiece 300 and the first workpiece 200 are clamped to each other before welding, and the second workpiece 300 can be positioned in the X-Y plane through the mechanism of the second workpiece 300 and the first workpiece 200. By arranging the pressing member 35, the second workpiece 300 can be effectively pressed in the Z-axis direction during the welding process, thereby improving the stability of the position of the second workpiece 300 in the Z-axis direction and being beneficial to improve the welding effect. It can be understood that when the pressing member 35 is arranged on the second workpiece 300, the pressing member 35 avoids the position of the first workpiece 200 and the second workpiece 300, thereby avoiding affecting the welding.

[0037] In some embodiments, referring to Figure 3 and Figure 4 , a plurality of positioning holes 301 are arranged on the second workpiece 300, a plurality of positioning pins 36 corresponding to the positioning holes 301 are arranged on the side of the carrier 32 for carrying the second workpiece 300, and a plurality of clamping holes 351 corresponding to the positioning pins 36 are arranged on the pressing member 35. Each positioning pin 36 is inserted into the corresponding positioning hole 301 and clamping hole 351 to position the second workpiece 300 and the pressing member 35. The positioning holes 301 on the second workpiece 300 can be two, three, four, etc., the number of positioning pins 36 can be two, three, four, etc., the number of clamping holes 351 can be two, three, four, etc., and the positions of the positioning holes 301, the positioning pins 36 and the clamping holes 351 correspond to each other. In this way, when the second workpiece 300 is installed, the second workpiece 300 can be positioned by inserting the positioning pin 36 into the corresponding positioning hole 301, so as to avoid displacement of the second workpiece 300 during the material moving process. The pressing member 35 can be positioned by inserting the positioning pin 36 into the corresponding clamping hole 351, so as to avoid displacement of the pressing member 35 during the material moving process.

[0038] In some embodiments, referring to Figure 3 and Figure 4The end of the positioning pin 36 away from the carrier 32 is provided with a clamping groove 361, the clamping hole 351 includes a penetrating portion 3511 and a clamping portion 3512 connected along the Y-axis direction, the positioning pin 36 is inserted into the pressing piece 35 through the penetrating portion 3511, and the clamping portion 3512 cooperates with the clamping groove 361 to clampingly fix the pressing piece 35 and the positioning pin 36. The clamping groove 361 on the positioning pin 36 can be symmetrically provided with two, and the groove bottom of each clamping groove 361 extends along the Y-axis direction. The structure of the penetrating portion 3511 is matched with the cross-sectional structure of the positioning pin 36, and the structure of the clamping portion 3512 is matched with the cross-sectional structure of the position where the clamping groove 361 is located. In this way, when the pressing piece 35 is installed, the penetrating portion 3511 is opposite to the positioning pin 36, so that the positioning pin 36 penetrates through the penetrating portion 3511, and when the clamping portion 3512 is opposite to the clamping groove 361, the pressing piece 35 is slid along the Y-axis direction, so that the side edge of the clamping portion 3512 abuts against the groove bottom of the clamping groove 361. At this time, the clamping groove 361 clampingly fixes the pressing piece 35, so that the pressing piece 35 can be limited in the Z-axis direction, thereby improving the stability of the pressing piece 35 pressing the second workpiece 300.

[0039] In some embodiments, referring to Figure 3 and Figure 4 , the pressing piece 35 is provided with a plurality of elastic portions 352 arranged towards the second workpiece 300, and the plurality of elastic portions 352 are used to elastically abut against the second workpiece 300 when the pressing piece 35 is clamped in the clamping groove 361 of the positioning pin 36. The elastic portion 352 can be formed by bending a part of the structure of the pressing piece 35, which has elasticity, or the elastic portion 352 is a spring structure connected to the body of the pressing piece 35, and the number of the elastic portion 352 can be four, six, eight, etc. By arranging a plurality of elastic portions 352, the second workpiece 300 can be elastically abutted by the plurality of elastic portions 352 when the pressing piece 35 is clamped in the clamping groove 361, thereby further improving the stability of the pressing of the second workpiece 300.

[0040] In some embodiments, referring to Figure 1 and Figure 3 , the machining bin 12 is provided with an inlet 121 corresponding to the material moving driving piece 20, and the inlet 121 is provided with a light curtain 122 for shielding the light of the inlet 121. The inlet 121 provided on the machining bin 12 facilitates the moving in and out of the first workpiece 200 and the second workpiece 300, but strong light, electric arc and other dangerous factors may be generated during the welding process. The arrangement of the light curtain 122 can effectively block these strong light, preventing it from causing harm to the eyes of the operator. The light curtain 122 can also prevent sparks, splashes and other things generated during the welding process from flying out of the inlet 121, causing burns or other injuries to the operator.

[0041] In some embodiments, referring to Figure 1The welding device 100 is further provided with a safety grating 124 arranged close to the feeding port 121. The safety grating 124 can improve the safety of the welding device 100.

[0042] The working process of the welding device 100 provided by the embodiment of the present application is as follows:

[0043] Firstly, the first workpiece 200 is placed in the space formed by the first half groove 321 on the two sides of the loading member 32 and the second half groove 341 of the clamping member 34, and the clamping driving member 33 drives the clamping member 34 to firmly clamp and position the first workpiece 200. At the same time, the second workpiece 300 is placed on the loading member 32, and the positioning pin 36 on the loading member 32 and the positioning hole 301 on the second workpiece 300 are matched to preliminarily position the second workpiece 300. Then, the pressing member 35 is arranged on the side of the second workpiece 300 away from the loading member 32 by matching the clamping hole 351 on the pressing member 35 with the positioning pin 36, and the second workpiece 300 is further fixed. When the clamping hole 351 on the pressing member 35 is clamped in the clamping groove 361 of the positioning pin 36, the elastic part 352 on the pressing member 35 elastically abuts against the second workpiece 300, so that the second workpiece 300 can be kept stable during the welding process.

[0044] Then, the positioning assembly 30 carrying the first workpiece 200 and the second workpiece 300 is moved into the processing bin 12 along the Y-axis direction by the material moving drive, and the first workpiece 200 and the second workpiece 300 are moved below the transverse driving member 42. Before welding, the detector 44 of the welding assembly 40 can move in the X-Z plane under the driving of the transverse driving member 42 and the longitudinal driving member 43 to detect the first workpiece 200 and the second workpiece 300, so as to ensure that the first workpiece 200 and the second workpiece 300 meet the welding requirements. Then, the welding machine 41 can move flexibly in the X-Z plane under the joint action of the transverse driving member 42 and the longitudinal driving member 43, and reaches the appropriate welding position to weld the first workpiece 200 and the second workpiece 300. The light shield curtain 122 is used to shield the strong light generated during the welding process, and the safety grating 124 is arranged close to the feeding port 121 to prevent personnel from accidentally approaching the feeding port 121 and causing injury, so as to ensure the safe operation of the welding process.

[0045] After the welding is completed, the positioning assembly 30 carrying the first workpiece 200 and the second workpiece 300 is moved out of the processing bin 12 by the material moving drive 20. It can be understood that the material moving drive 20 can be provided with two, and the positioning assembly 30 is correspondingly provided with two. When one of the material moving drives 20 moves the positioning assembly 30 carrying the first workpiece 200 and the second workpiece 300 into the processing bin 12, the operating personnel can assemble the first workpiece 200 and the second workpiece 300 on the other positioning assembly 30. The two groups of material moving drives 20 and positioning assemblies 30 work alternately, which can further improve the welding efficiency.
