Then, the positional relationship between the upper and lower covers is locked by laser welding. The current welding method is relatively simple and requires workers to frequently change and flip the covers. During the welding process, the welding trajectory is difficult to control, and there is a possibility of incomplete welding.

[0003] Therefore, a laser welding device for the top and bottom covers is still needed to solve the above problems. Utility Model Content

The two ends of the second fixing member are slidably connected to the vertically arranged second slide rail, and the first slide rail is connected to the second fixing member. The second driving member is used to drive the laser light source to move in the Z-axis.

[0013] The feeding station and welding station are equipped with a third slide rail and a fixed seat that slides to connect the third slide rail. The fixed seat is also connected to a third driving component, which is used to drive the fixed seat to move along the third slide rail in the Y direction.

[0014] In one embodiment, a pre-pressing component is further included, the pre-pressing component comprising a pressing part and a linear module, the pressing part being connected to the movable end of the linear module, and the bottom of the pressing part being annular and the top having an outwardly flared through opening for abutting against the end cap and the housing, and avoiding the laser's preset trajectory on the end cap.

[0026] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided to make the present invention more comprehensive and complete, and to fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore repeated descriptions of them will be omitted.

[0027] The terms used to describe position and direction in this utility model are illustrated with the accompanying drawings, but changes can be made as needed, and all such changes are included within the scope of protection of this utility model.

[0028] Reference Figure 1-5This utility model provides a laser welding device for upper and lower covers, comprising: a laser source 1, wherein the laser source 1 is connected to the top of the frame; a corresponding loading station 2, which is provided with an actuator for picking up / placing the end cover to be welded; a corresponding welding station 3, which is used to weld the actuator end cover and the housing according to a preset trajectory; and a rotating assembly 4, which includes a rotating disk 41 and a driving component 42, the rotating shaft of the driving component 42 being coaxially connected to the rotating disk 41; the loading station 2 and the welding station 3 being located on different sides of the top surface of the rotating disk 41; and a blocking component on the rotating disk 41 between the loading station 2 and the welding station 3, which is used to switch the corresponding loading station 2 and the welding station 3 during rotation.

[0029] Located on the rotating disk 41, below the laser source 1, are the corresponding welding stations 3 and the corresponding loading station 2 at the worker's end. During operation, the worker first places the housing and upper cover or the housing and lower cover assembly on the corresponding fixture at the loading station 2. Then, under the conveying of the rotating disk 41, the placed housing and upper cover or housing and lower cover assembly are rotated to the welding station 3. Then, the laser source 1 heats the edge of the upper cover or lower cover by following a preset trajectory, so that the upper cover and lower cover are welded to different positions of the housing. The worker does not need to weld the upper cover of one actuator, then flip it over to weld the other side, and then put the next actuator to be welded. Each corresponding welding station 3 is equipped with two sets of placement bases, on which the assembled actuators can be placed in sequence. Then, under the action of the rotating disk 41, the assembled actuators are sent to the welding station 3 in sequence for welding with the laser source 1, reducing the frequency of workers flipping individual actuators and improving the production rhythm.

[0030] In one embodiment, the laser source 1 is connected to the top of the welding station 3 via a moving module. The moving module includes an X-axis module 5 and a Z-axis module 6. The X-axis module 5 includes a first slide rail 51, a first fixing member 52, and a first driving member 53. The two ends of the first fixing member 52 are slidably connected to the first slide rail 51. The laser source 1 is connected to the first fixing member 52. The first driving member 53 is used to drive the first fixing member 52 to move along the first slide rail 51 in the X direction.

[0031] The Z-axis module 6 includes a second slide rail 61, a second fixing member 62, and a second driving member 63. The two ends of the second fixing member 62 are slidably connected to the vertically arranged second slide rail 61. The first slide rail 51 is connected to the second fixing member 62. The second driving member 63 is used to drive the laser light source 1 to move in the Z-axis.

[0032] The loading station 2 and welding station 3 are equipped with a third slide rail 7 and a fixed seat that slidably connects to the third slide rail 7. The fixed seat is also connected to a third driving component 81, which drives the fixed seat to move along the third slide rail 7 in the Y direction. Through the cooperation of the X-axis module 5 and Z-axis module 6, which can move in coordination with each other, the laser light source 1 can freely follow a preset welding trajectory, traversing a dense path on the upper or lower cover, effectively avoiding missed or incorrect welding and improving the welding quality of the product.

[0033] In one embodiment, a pre-pressure component 9 is further included. The pre-pressure component 9 includes a pressing part 91 and a linear module 92. The pressing part 91 is connected to the movable end of the linear module 92. The bottom of the pressing part 91 is annular, and the top has an outwardly flared through-hole for abutting against the end cap and the housing, and avoiding the laser's predetermined trajectory on the end cap. The bottom of the pressing part 91 abuts against the end cap and the housing, keeping them in a tight fit. During laser welding, it provides downward pressure to ensure the upper and lower caps fit tightly against the housing and avoids the laser welding trajectory. The outwardly flared through-hole at the top acts as a beam convergence point, preventing small deviations in the beam from directly hitting other parts of the housing, thus providing more stable protection.

[0034] In one embodiment, the rotating assembly 4 is provided with fixed seats corresponding to the opposite loading station 2 and the opposite welding station 3. The fixed seats include a first fixed seat 82 and a second fixed seat 83. The first fixed seat 82 includes a placement groove for vertically placing the actuator. The opening shape of the placement groove matches the overlapping surface shape of the bottom shell of the actuator. The second fixed seat 83 includes a first holding part and a second holding part 832 that can be separated from or brought close together. When the first holding part and the second holding part 832 are close together, they form a clamping groove that can hold the bottom stepped surface of the lower edge of the actuator. The first fixed seat 82 is used to place a structure where the actuator is larger at one end and smaller at the other. The second fixed seat 83, with the first holding part and the second holding part 832, can stably clamp irregularly shaped shell structures, clamping the structures on both sides and exposing the top of the structure to be welded. The first fixed seat 82 and the second fixed seat 83 can stably fit between shells and upper and lower covers with different fixing requirements, achieving a good clamping effect and initiating a good welding effect.

[0035] In one embodiment, the first clamping part 831 and the second clamping part 832 are connected by a drive telescopic member 84. The moving end of the drive telescopic member 84 is connected to the first clamping part 831, and the fixed end is connected to the second clamping part 832. The drive telescopic member 84 can be an electric telescopic rod or a pneumatic telescopic rod, which drives the first clamping part 831 and the second clamping part 832 to automatically clamp and fix them by means of electricity or pneumatics.

[0036] In one embodiment, the bottom shaft of the rotating disk 41 is connected to a drive motor via a reducer 43. The reducer 43 amplifies the torque output by the motor, enabling the rotating disk 41 to rotate stably.

[0037] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and alterations to the above embodiments within the scope of the present invention without departing from the principles and spirit of the present invention, and all such changes should fall within the protection scope of the claims of the present invention.
