Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] like Figures 1 to 15As shown, an embodiment of the present invention provides a button battery laser ring welding device, including a machine platform 1, a finished product unloading linear module 2 is fixedly installed in the middle position of the top of the machine platform 1, a loading linear module 3 is fixedly installed on the rear side of the top of the machine platform 1, a loading linear module 3 is slidably installed on the top of the loading linear module 3, a fork line positioning fixture 5 is fixedly installed on the top of the loading linear module 3, a positioning groove 6 is placed on the top of the fork line positioning fixture 5, a grasping robot 8 is fixedly installed on the top of the machine platform 1, a laser height adjustment module 10 is fixedly installed on the front side of the top of the machine platform 1, a laser angle adjustment module 11 is fixedly installed on the right side of the laser height adjustment module 10, a laser welder 12 (also including a laser welding camera) is fixedly installed on the right end of the laser angle adjustment module 11, a fixing frame 13 is fixedly installed on the top of the machine platform 1, a pressing module 14 is fixedly installed on the top of the fixing frame 13, and the bottom end of the pressing module 14 is movable A lifting mechanism 15 is installed, and a cover plate pressing positioning mechanism 16 is fixedly installed at the bottom end of the lifting mechanism 15, a positioning fixture moving module 17 is fixedly installed on the top of the machine platform 1, a moving platform 18 is slidably installed on the top of the positioning fixture moving module 17, a composite shell positioning mechanism 19 is installed on the top of the moving platform 18, a rotating cylinder 20 is fixedly installed at the bottom of the moving platform 18, a positioning lifting mechanism 21 is fixedly installed on the back of the moving platform 18, a cover plate positioning mechanism 22 located above the composite shell positioning mechanism 19 is fixedly installed on the front of the positioning lifting mechanism 21, a positioning plate 23 is fixedly installed on the top of the cover plate positioning mechanism 22, a cover plate positioning block 24 is fixedly installed on the top of the positioning plate 23, a vertical shaft 25 is movably installed on the top of the composite shell positioning mechanism 19, and the top end of the vertical shaft 25 extends upward to the inside of the positioning plate 23, and the output shaft of the rotating cylinder 20 is fixedly connected to the vertical shaft 25.

[0040] The device is composed of two sets of identical equipment for improving work efficiency. Here, a set of equipment is taken as an example to explain the work process. The staff places the button battery composite shell together with the cover plate in the positioning groove 6 in the fork line positioning fixture 5, and then the loading linear module 3 transports the loading platform 4 to the appropriate position. The grasping robot 8 rotates and controls the three-grab component 9 at the same time. The button battery composite shell and the cover plate in the positioning groove 6 are grasped by the three-grab component 9 and placed at the end position of the vertical axis 25 in the cover plate positioning block 24. Then, the positioning fixture moving module 17 drives the moving platform 18 to move, so that the cover plate positioning block 24 on one side is vertically aligned with the cover plate pressing positioning mechanism 16. Then, under the action of the pressing module 14, the lifting mechanism 15 drives the cover plate pressing positioning mechanism 16 to move downward together, and the cover plate pressing positioning mechanism 16 is driven by the lifting mechanism 15 to move downward together. The cover plate located at the top of the button battery composite shell inside the cover plate positioning block 24 is contacted and pressed down by the internal spring elastic force. At the same time, the positioning lifting mechanism 21 drives the cover plate positioning mechanism 22, the positioning plate 23 and the cover plate positioning block 24 to move downward together, and the vertical shaft 25 remains unchanged, so that the connection position between the button battery composite shell and the cover plate is gradually exposed, and then the vertical shaft 25 is driven to rotate by the rotating cylinder 20, thereby driving the button battery composite shell and the cover plate to rotate together. At this time, the laser welder 12 is used to perform a ring welding operation on the connection position between the button battery composite shell and the cover plate; then, the positioning fixture moving module 17 drives the moving platform 18 to move to the other side to continue the ring welding operation, and the welded side is grasped by the grasping robot 8 to place the finished product on the finished product unloading linear module 2, and transported out through the finished product unloading linear module 2, and the operation is repeated in this way.

[0041] Among them, a positioning groove 6 and a grabbing groove 7 are opened on the top of the fork line positioning fixture 5. There are three grabbing grooves 7 and they are evenly distributed around the positioning groove 6. The number and position distribution of the grabbing grooves 7 correspond to the three-grabbing components 9. The positioning groove 6 is used to place the button battery composite shell and cover plate.

[0042] Since the grasping groove 17 and the three-grasp assembly 9 are designed to correspond to each other, when the three-grasp assembly 9 grasps the button battery composite shell and the cover plate inside the positioning groove 6, due to the design of the grasping groove 17, the three-grasp assembly 9 can enter the interior of the grasping groove 17, and then increase the grasping area of ​​the button battery composite shell and the cover plate combination, thereby improving the stability of the three-grasp assembly 9 during grasping.

[0043] Among them, a three-grasp assembly 9 is fixedly installed at the bottom end of the grasping robot 8, and the position of the three-grasp assembly 9 corresponds to the position of the grasping slot 7. The three-grasp assembly 9 is used to clamp the button battery composite shell and the cover plate.

[0044] Since the number and angle of the three-claw assembly 9 and the grasping groove 7 correspond to each other, the three-claw assembly 9 extends into the interior of the grasping groove 7 under the cooperation of the three-claw assembly 9 and the grasping groove 7, thereby increasing the contact area of ​​the button battery composite shell and the cover plate combination in the positioning groove 6 and improving the stability during grasping.

[0045] A guide column 26 is fixedly mounted at the bottom end of the cover plate positioning mechanism 22 , and the bottom end of the guide column 26 passes through the composite shell positioning mechanism 19 downward. There are three guide columns 26 , which are evenly distributed around the vertical axis 25 .

[0046] Due to the design of the guide column 26, when the positioning and lifting mechanism 21 drives the cover positioning mechanism 22, the positioning plate 23 and the cover positioning block 24 to move downward, the guide column 26 moves downward together. The guide column 26 can play a good limiting role in the downward movement, thereby ensuring the stability of the movement.

[0047] Among them, an inclined groove 27 is opened at the end of the cover positioning block 24, and three grabbing grooves 28 are opened on the top of the positioning plate 23. The grabbing grooves 28 are located between adjacent cover positioning blocks 24, and the number and position of the grabbing grooves 28 correspond to the three grabbing components 9.

[0048] Due to the inclined design of the inclined groove 27, the circumference of the top opening position of the cover positioning block 24 is larger, so when the button battery composite shell and the cover are placed on the inner side of the three cover positioning blocks 24, the fault tolerance rate is higher, which facilitates the combination of the button battery composite shell and the cover to smoothly enter and contact with the top of the vertical axis 25.

[0049] Among them, a finished product unloading mechanism 29 is arranged at the right end of the machine 1, a finished product loading platform 31 is arranged on the left side of the finished product unloading mechanism 29, a vertical linear module 30 located on the left side of the finished product loading platform 31 is arranged on the left side of the finished product unloading mechanism 29, and a horizontal linear module 32 located above the finished product loading platform 31 is arranged on the left side of the finished product unloading mechanism 29.

[0050] Since the finished product unloading mechanism 29 is designed as an intelligent storage equipment commonly used by button battery processing companies, the empty finished product loading platform 31 inside the finished product unloading mechanism 29 can replace the full finished product loading platform 31 through the horizontal linear module 32, and the full finished product loading platform 31 can be transported downward by utilizing the vertical linear module 30 and finally stored at the bottom of the finished product unloading mechanism 29 for taking out by the staff.

[0051] Among them, a spring component is arranged inside the cover plate pressing down positioning mechanism 16 to realize the extension and retraction operation of the pressure head at the bottom end of the cover plate pressing down positioning mechanism 16.

[0052] The spring assembly refers to a simple mechanism with a spring commonly seen on the market, which belongs to the common prior art. Through the setting of the spring assembly, the pressure head of the cover plate pressing down positioning mechanism 16 can be lifted up and down. After contacting the cover plate, the spring assembly will bear the excess descending distance of the lifting mechanism 15 to prevent the cover plate from being damaged due to excessive squeezing.

[0053] The fixing frame 13 and the cover plate pressing down positioning mechanism 16 are aligned with the same longitudinal vertical line, and the corresponding positions are maintained, so that the positioning is achieved while the welding operation is performed.

[0054] The fixing frame 13 and the cover plate pressing and positioning mechanism 16 are aligned with the same longitudinal vertical line, which can ensure the position accuracy of laser welding.

[0055] When the cover plate positioning block 24 is driven by the positioning and lifting mechanism 21 to move downward, the bottom horizontal position of the inclined slot 27 is finally located in the middle and lower part of the button battery composite shell and does not separate from the button battery composite shell.

[0056] Since the horizontal position of the bottom end of the inclined groove 27 is finally located in the lower middle part of the button battery composite shell and does not separate from the button battery composite shell, it can not only effectively limit the button battery composite shell to prevent its position shift, but also expose the connection position between the button battery composite shell and the cover plate to facilitate laser welding operations.

[0057] Among them, the depth value of the positioning groove 6 in the fork line positioning fixture 5 is greater than the depth value of the grabbing groove 1 7 in the fork line positioning fixture 5, and there is a height difference between the grabbing groove 1 7 and the positioning groove 6.

[0058] Due to the height difference between the grabbing groove 7 and the positioning groove 6, the positioning groove 6 can be used to limit the combination of the button battery composite shell and the cover plate. At the same time, the grabbing groove 7 facilitates the grabbing operation of the button battery composite shell and the cover plate combination.

[0059] Working principle and usage process:

[0060] The staff places the button battery composite shell and the cover plate in the positioning groove 6 in the fork line positioning fixture 5, and then the loading linear module 3 transports the loading platform 4 to the appropriate position, and then the grasping robot 8 rotates and controls the three-grasping component 9 at the same time, and the button battery composite shell and the cover plate in the positioning groove 6 are grasped by the three-grasping component 9, and placed at the end position of the vertical axis 25 in the cover plate positioning block 24, and then the positioning fixture moving module 17 drives the moving platform 18 to move, so that the cover plate positioning block 24 on one side is vertically aligned with the cover plate pressing positioning mechanism 16, and then under the action of the pressing module 14, the lifting mechanism 15 drives the cover plate pressing positioning mechanism 16 to move downward together, and the cover plate located at the top of the button battery composite shell inside the cover plate positioning block 24 is contacted by the cover plate pressing positioning mechanism 16 and pressed down by the internal spring elastic force, and at the same time, the positioning lifting mechanism 21 drives the cover plate positioning mechanism 22 and the positioning plate 23 and the cover plate positioning block 24 move downward together, and the vertical shaft 25 remains unchanged, so that the connection position between the button battery composite shell and the cover plate is gradually exposed, and then the vertical shaft 25 is driven to rotate by the rotating cylinder 20, thereby driving the button battery composite shell and the cover plate to rotate together, and at this time, the laser welder 12 performs a ring welding operation on the connection position between the button battery composite shell and the cover plate; and then the positioning fixture moving module 17 drives the moving table 18 to move to the other side to continue the ring welding operation, and the welded side is grabbed by the grabbing robot 8 to take out the finished product and place it on the finished product unloading linear module 2, and transported out by the finished product unloading linear module 2, and such a reciprocating cycle operation is performed.
