By opening the first electric cylinder and allowing the first limit block to enter the first limit groove, the turntable can be limited and fixed, so that the workpiece in the first placement groove can be quickly moved to the front of the workpiece in the second placement groove, facilitating the laser welding machine to weld the parts where the two workpieces fit together. The above-mentioned prior art solution has the following shortcomings: in this device, since one workpiece is vertically inserted into the interior of the first placement groove and the other workpiece is horizontally inserted into the interior of the second placement groove, when the adjacent surfaces of the two workpieces are welded, due to the presence of a pressure block at the top of the workpiece located in the second placement groove, it is difficult to directly take the complete welded workpiece from the two placement grooves, so there is room for improvement.

[0022] See also Figures 1-4 The utility model provides an embodiment of a laser welding machine conveying device, comprising a base 1, fixed columns 7 are installed on both sides of the top of the base 1, and the outside of the fixed columns 7 is sleeved with a conveying disc 2, and the side walls of the two conveying discs 2 are abutted against each other, and the bottom ends of the two conveying discs 2 are connected with a transmission component 9, and the top of the conveying disc 2 is evenly spaced and annularly distributed with multiple fixed plates 3, and the side of the fixed plate 3 close to the fixed column 7 is opened with a through hole 4, and one side of the fixed plate 3 is provided with a limit component 5;

[0023] The limiting assembly 5 includes two hinged plates 504 mounted on one side of the fixed plate 3 in an upper and lower arrangement. A rotating plate 501 is rotatably connected between the two hinged plates 504. Two springs 502 are mounted on the inner side of the rotating plate 501, and one end of each spring 502 is connected to one side of the fixed plate 3. Two buffer rings 503 are mounted on the side of the fixed plate 3 close to the rotating plate 501. The buffer rings 503 are sleeved on the outside of the springs 502, and the outer sides of the buffer rings 503 abut against the inner wall of the rotating plate 501.

[0024] The rotating plate 501 and the fixed plate 3 form a U-shaped structure when viewed from above, and the length of the rotating plate 501 is smaller than the bending length of the fixed plate 3;

[0025] Specifically, such as Figure 1 、 Figure 4 As shown, when in use, the outward flipping capability of the limit assembly 5 is utilized so that when the two workpieces are welded, the two fixing plates 3 generate a pushing force on the workpieces so as to directly push the workpieces to the outside of the conveying tray 2 to realize automatic unloading of the workpieces;

[0026] The limiting assembly 5 is located on the side of the fixed plate 3 close to the rotation direction of the conveyor disc 2, and a docking mechanism 8 is connected between the two fixed columns 7 to push the workpieces on the inner sides of the two opposite fixed plates 3 closer to each other for welding;

[0027] The docking mechanism 8 includes a fixing tube 1 801 respectively mounted on the two fixing columns 7, and one end of each fixing tube 801 is penetrated by a piston rod 1 802, the bottom ends of each fixing tube 801 are penetrated by the interior of the fixing column 7 and extend to the bottom end of the base 1, and the bottom ends of the two fixing tubes 801 are connected to a fixing tube 2 803, one end of the fixing tube 2 803 is penetrated by a piston rod 2 804, and one end of the piston rod 2 804 is mounted with an electric telescopic rod 805, and one end of the electric telescopic rod 805 is connected to the bottom end of the base 1 through a mounting block;

[0028] The first fixed pipe 801 and the second fixed pipe 803 are connected to each other and filled with lubricating oil. The cross section of the first fixed pipe 801 is L-shaped, and the cross section of the second fixed pipe 803 is T-shaped.

[0029] The piston rod 802 is retracted along the axial direction of the fixed column 7, and the height of the piston rod 802 is adapted to the height of the through hole 4.

[0030] Specifically, such as Figure 1 、 Figure 3 As shown, when in use, the lubricating oil inside the fixed tube 1 801 and the fixed tube 2 803 is used as a driving force to adjust the position of the piston rod 1 802, and the adjustment lengths of the two piston rods 1 802 are synchronized and consistent;

[0031] A conveyor belt 6 is installed on one side of the top of the base 1, and the conveyor belt 6 is located below the opposing sides of the two conveyor discs 2. The bottom ends of the two conveyor discs 2 are connected to a transmission assembly 9;

[0032] The transmission assembly 9 includes a gear ring 901 mounted on the bottom ends of the two conveyor trays 2, and a transmission gear 902 is meshed on one side of the gear ring 901. The two transmission gears 902 mesh with each other. A motor 904 is mounted on the bottom end of the base 1, and the output end of the motor 904 extends to the top end of the base 1 and is mounted with a driving gear 903. The outer side of the driving gear 903 meshes with the outer side of the gear ring 901 on one side, and the two gear rings 901 have the same angular velocity.

[0033] Specifically, such as Figure 1 、 Figure 2 and Figure 3 As shown, when in use, the transmission gear 902 is utilized to facilitate the two conveyor discs 2 to rotate differently and in opposite directions, thereby facilitating the docking of the two workpieces and facilitating subsequent unloading.

[0034] Working Principle: When using the present invention, first, two groups of workpieces to be welded are placed on the left and right sets of fixed plates 3 respectively, and combined with the corresponding limiting components 5 on each fixed plate 3, the rotating plate 501 cooperates with the fixed plate 3 to achieve the fixation of the workpieces, so that multiple workpieces can be fixed on the left and right conveyor trays 2 respectively;

[0035] Secondly, the motor 904 is started to rotate the driving gear 903, thereby rotating the gear ring 901 on one side, and utilizing the transmission effect of the transmission gear 902 to rotate the gear ring 901 on the other side, so that the two conveyor plates 2 rotate in the same direction, so as to facilitate the rotation and docking of the left and right groups of workpieces. When the two workpieces move to the point of abutment, the motor 904 is stopped, and the electric telescopic rod 805 is started to extend, so that the piston rod 804 pushes the lubricating oil inside the fixed tube 803 to move inward, so that the lubricating oil inside the piston rod 1 802 pushes the piston rod 1 802 closer to the direction of the workpiece, so that the piston rod 1 802 pushes the workpiece, so that the two workpieces abut each other and facilitate welding.

[0036] Finally, when welding is completed, the electric telescopic rod 805 is started to reset, so that the piston rod 2 804 is reset, thereby resetting the lubricating oil inside the fixed tube 1 801, and under the action of external pressure, the piston rod 1 802 is reset, and the motor 904 is started to rotate, so that the two conveyor discs 2 continue to rotate. Since the workpiece forms a whole, the fixed plate 3 cannot drive the workpiece to move with one conveyor disc 2 during the rotation process, so that the left and right fixed plates 3 form a driving force on the workpiece, so that the workpiece pushes the rotating plate 501 away, so that the spring 502 is extended, and then the workpiece is moved to the conveyor belt 6. Under the continuous transmission of the conveyor belt 6, the welded workpiece is unloaded outward.
