[0036] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation modes.

[0037] Example 1, as Figure 1 and Figure 2 shown, a lithium battery cap automatic assembly and welding device includes a plurality of bases 1, a first blanking component 2 is fixedly connected to the upper ends of the plurality of bases 1, a matching component 3 is fixedly connected to the left side of the first blanking component 2, a transmission component 5 is fixedly connected to the upper right side of the matching component 3, a second blanking component 4 is fixedly connected to the upper left rear of the first blanking component 2, and a transportation component 6 is fixedly connected to the upper left side of the matching component 3.

[0038] During the implementation of this embodiment, the operator needs to place a collection box on the left side of the cooperation component 3, turn on the control system inside the first blanking component 2, and then adjust the control system inside the first blanking component 2 to control the start of the power sources inside the transmission component 5 and the transportation component 6. Further, the operator needs to stand at the rear of the connection between the first blanking component 2 and the cooperation component 3 and prepare to put the lithium battery housing into the transmission component 5. Subsequently, the components inside the transmission component 5 will cooperate with each other through the structure, and then clamp the lithium battery housing put by the operator. During the process of clamping the lithium battery housing, the transmission component 5 will drive the lithium battery housing to rotate. Thus, when passing through the second blanking component 4, an appropriate amount of positive and negative electrode materials will be put in. Further, when the transmission component 5 drives the lithium battery housing to rotate to the cooperation component 3, the components inside the cooperation component 3 will cooperate with each other to push the battery cap to the lithium battery. Further, the transmission component 5 will drive the lithium battery with the cap to be transported to the right side of the transportation component 6. At this time, the transportation component 6 will correct and transport the lithium battery rotated and transported by the transmission component 5, and then weld the lithium battery through the welding component inside the cooperation component 3.

[0039] By setting up the cooperation between the first blanking component 2 and the second blanking component 4, the inside of the lithium battery housing placed by the operator can be automatically filled, so as to ensure that the filling of each battery housing meets the standard. Further, by setting up the cooperation among the cooperation component 3, the second blanking component 4 and the transmission component 5, while adding an appropriate amount of filling materials to the lithium battery housing, the lithium battery cap can be stably installed on the upper part of the lithium battery housing, so as to facilitate the welding of the two.

[0040] Specifically, in order to achieve the purpose of clamping the lithium battery housing while filling the positive and negative electrode materials inside the lithium battery housing, please refer to Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 、and Figure 10 As shown in, the first blanking component 2 includes a first support platform 21. The front part of the upper end of the first support platform 21 is fixedly connected with a first support plate 22. The upper end of the first support plate 22 is fixedly connected with a conveying component 23. The right side of the rear part of the upper end of the first support plate 22 is fixedly connected with a control end 24. The conveying component 23 includes a first support leg 231. The upper end of the first support leg 231 is fixedly connected with a vibrating feeding tray 232. The front side of the upper part of the outer surface of the vibrating feeding tray 232 is fixedly connected with a first transmission track 233. The left end of the first transmission track 233 is fixedly connected with a second transmission track 234. A first groove 235 is opened on the left side of the second transmission track 234.

[0041] During the implementation of this embodiment, control data is sent from the control terminal 24 to the vibrating feeding tray 232, which can then start the vibrating feeding tray 232. Subsequently, the battery cap is oriented in the correct direction and vibrated into the inner cavity of the first transfer track 233. Then, through the cooperation between the first transfer track 233 and the second transfer track 234, the lithium battery cap can be transported into the inner cavity of the first groove 235, so as to install it on the lithium battery housing containing the positive and negative electrode materials.

[0042] It should be noted that the above-mentioned control terminal 24 is a mature technical means in existing control devices. The present invention utilizes its controllable functions and will not elaborate on its structure and principle.

[0043] Furthermore, the above-mentioned vibrating feeding tray 232 is a mature technical means in existing control devices. The present invention utilizes its function of automatically and orderly orienting disordered workpieces through vibration and accurately transporting them to the next process to achieve automatic feeding, and will not elaborate on its structure and principle.

[0044] Further, please refer to Figure 5 As shown, the second blanking component 4 includes four second support legs 41. The bottoms of the four second support legs 41 are fixedly connected to the left rear part of the upper end of the first support platform 21. The upper ends of the four second support legs 41 are fixedly connected to a second support plate 42. A sorting groove 43 is fixedly connected to the upper end of the second support plate 42. A blanking groove 44 is fixedly connected to the bottom of the sorting groove 43. An infrared detection end 45 is fixedly connected to the bottom of the front end of the blanking groove 44. A blanking pipe 46 communicating with the bottom inner cavity of the blanking groove 44 is fixedly connected to the rear side of the infrared detection end 45. The bottom end of the blanking pipe 46 is matched with the upper end of the transfer component 5.

[0045] During the further implementation process, by adding a certain amount of positive and negative electrode materials into the inner cavity of the sorting groove 43, through the cooperation with the blanking groove 44, the filling materials in the inner cavity of the sorting groove 43 can be stacked in the front part of the inner cavity of the blanking groove 44. Then, through the cooperation between the infrared detection end 45 and the solenoid valve installed inside the blanking pipe 46, the filling materials in the front part of the inner cavity of the blanking groove 44 can be quantitatively put into the inner cavity of the lithium battery housing, thus avoiding friction and damage caused by external forces such as vibration, and improving the service life and safety of the battery pack.

[0046] It should be further noted that the above-mentioned external detection end 45 is a mature technical means in existing detection devices. The present invention utilizes its detectable functions and will not elaborate on its structure and principle.

[0047] Further, the electronic valve mentioned above is a conventional design in the prior art. When the infrared detection end 45 detects the upper end of the transmission component 5, it will send data to the solenoid valve in the inner cavity of the feeding pipe 46. Then, after receiving the data, the solenoid valve will open, thereby filling the inner cavity of the lithium battery shell with materials. The operating principle of the solenoid valve will not be elaborated too much in this solution.

[0048] Further, please refer to Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown in, the matching component 3 includes a second support platform 31. The right side of the second support platform 31 is fixedly connected to the left side of the first support platform 21. The left side of the upper end of the second support platform 31 is fixedly connected to a welding robot arm 32. The right side of the upper end of the second support platform 31 is fixedly connected to a matching block 33. A pushing plate 34 is slidably connected to the inner surface of the matching block 33. A first connecting rod 35 is slidably connected to the front side of the pushing plate 34. The middle part of the first connecting rod 35 is rotatably connected to an ear 36. The rear end of the ear 36 is fixedly connected to the front end of the second support platform 31. A second groove 37 is formed in the right part of the front side of the second support platform 31. The bottom of the first connecting rod 35 is slidably connected to a sliding rod 38. A fixing ring 310 is fixedly connected to the outer surface of the sliding rod 38. A first spring 39 is fixedly connected to the front side of the fixing ring 310. The transmission component 5 includes a motor 51. The output end of the motor 51 is fixedly connected to a transmission column 52 through a coupling. A matching ring 53 is fixedly connected to the bottom of the outer surface of the transmission column 52. The upper part of the outer surface of the transmission column 52 is rotatably connected to a support pipe 54. The bottom end of the support pipe 54 is fixedly connected to the right side of the upper end of the second support platform 31. The front part of the outer surface of the matching ring 53 is matched with the sliding rod 38. The upper end of the transmission column 52 is fixedly connected to a rotating component 55. The rotating component 55 includes a detection plate 551. A U-shaped plate 552 is fixedly connected to the middle part of the upper end of the support pipe 54. The bottom end of the detection plate 551 is fixedly connected to a matching disc 553. A matching part 554 is rotatably connected to the inner cavity of the matching disc 553. The middle part of the bottom end of the matching disc 553 is fixedly connected to the upper end of the transmission column 52.

[0049] During the implementation process, when the motor 51 starts, it will drive the matching ring 53 to rotate through the cooperation of the coupling and the transmission column 52. Further, when the matching ring 53 rotates, through the arc groove formed on the outer surface, the sliding rod 38 can be driven to slide forward. While the sliding rod 38 slides forward, through the linkage cooperation among the first connecting rod 35, the ear 36, and the pushing plate 34, the lithium battery cap in the inner cavity of the first groove 235 can be pushed to the upper part of the lithium battery filled with filling materials;

[0050] After the mating ring 53 pushes the fixing ring 310 to a certain stroke, the spring 1 39 will, through its own resilience, drive the sliding rod 38 fixedly connected to the inner surface of the fixing ring 310 to slide backward. Then, through the cooperation of the connecting rod 1 35, the lug 36 and the pushing plate 34, the pushing plate 34 is retracted, so that the pushing plate 34 can continuously push the lithium battery cap, thereby realizing automated production and improving production efficiency.

[0051] Furthermore, during the implementation process, when the push plate 34 pushes the lithium battery cap onto the lithium battery shell, the motor 51 will drive the mating disk 553 to rotate through the transmission column 52, so that the several mating parts 554 in the circular array around the mating disk 553 can clamp the lithium battery shell placed by the operator, so that when transporting close to the transport component 6, the U-shaped plate 552 is disengaged from the limit and the clamping of the lithium battery shell is released.

[0052] It should be further explained that the detection board 551 and the infrared detection end 45 cooperate with each other, and the detection board 551 is a conventional design in the prior art. The present invention mainly utilizes the detection function of the detection board 551, and its structure and principle will not be elaborated.

A blanking block is provided on the right part of the positioning blanking plate 62 at the rear, and the middle parts of the upper ends of the two positioning blanking plates 62 are fixedly connected to a clamping component 63 set in a mirror image. The right sides of the upper ends of the two positioning blanking plates 62 are fixedly connected to a blocking component 65 set in a mirror image, and the bottoms of the two blocking components 65 are fixedly connected to a pumping component 64.

[0054] Furthermore, during the implementation process, a blanking block is provided on the right side of the positioning blanking plate 62 at the rear, and the blanking block can cooperate with the outer surface of the lithium battery so that the lithium battery can be stopped by the blanking block and slide to the upper end of the conveyor belt 61. Subsequently, the lithium battery shells are grouped by two blocking components 65, so that the subsequent welding robot arm 32 can perform continuous welding during welding. Furthermore, the lithium battery can be clamped by providing two clamping components 63, thereby avoiding unnecessary shaking of the lithium battery shell during the welding process of the welding robot arm 32, thereby ensuring production quality. Subsequently, the welded lithium battery will fall into the collection box placed by the operator on the left and wait for collection.

[0055] Further, it should be noted that: the conveyor belt 61 mentioned above is a conventional design in the prior art. The conveyor belt 61 is composed of two rotating wheels, a transmission belt and a micro motor. One of the rotating wheels is fixedly connected to the coupling at the output end of the micro motor, and the transmission belt is wound around the outer surfaces of the two transmission wheels. When the micro motor starts, it will drive the transmission wheels to rotate, so that the transmission belt can transport the lithium battery.

An electric telescopic rod 642 is fixedly connected to the front side of the fixed block 641. A fixing plate 643 is fixedly connected to the output end of the electric telescopic rod 642. A fixed rod 644 is fixedly connected to the upper side of the fixing plate 643. Plug heads 645 are fixedly connected to both the left and right sides of the fixed rod 644. The two plug heads 645 on the same side are both slidable in the inner cavities of the connecting pipe one 636 and the connecting pipe two 654.

[0057] In the process of this embodiment, when the electric telescopic rod 642 starts, it will drive the fixed rod 644 to slide in the inner cavities of the connecting pipe one 636 and the connecting pipe two 654 through the fixing plate 643 fixedly connected to the output end, and group the lithium battery housings by squeezing and pumping the hydraulic oil in the inner cavities of the housing one 631 and the housing two 651. At the same time of grouping, the clamping plate 635 welds the lithium battery housing and the cap through the cooperation of the sliding plate 632 and the two spring columns 634, so that the parallelization of the production process can be realized, and the production efficiency can be significantly improved.
