Technical Field

[0001] The present invention belongs to the technical field of battery production, and in particular relates to a full-automatic terminal welding device and a working method of the full-automatic terminal welding device. Background Art

[0002] Battery terminals are important components that connect batteries to external circuits. They are usually located on the positive and negative poles of the battery and are used to transmit current and maintain circuit connection. Terminals are usually designed to be firmly connected to the battery casing to ensure that they will not loosen or disconnect during use. Welding is one of the methods for fixing terminals.

[0003] After the vibration plate or other conveying device transfers the terminal to the placement rack, the required terminal is clamped by a clamp assembly. Since there is a certain distance between the two terminals of the battery and the terminals in the placement rack are in close contact with each other, the clamp assembly can only clamp the terminal once for welding, resulting in a slow welding speed of the terminal and affecting the welding efficiency of the terminal. Summary of the invention

[0004] The present invention aims to solve the problem that the clamp assembly in the prior art can only perform clamping welding once to adapt to the installation distance of the battery terminal, and proposes the following technical solution:

[0008] After the clamp bottom plate moves upward to the placement rack position, the moving slider drives the clamping piece to move into the placement rack to clamp the terminals, and automatically resets after clamping to disperse the terminals. The terminals are moved at a fixed distance using the different lengths of the moving slide slots so that they are at the top of the two battery poles. After the clamp bottom plate moves downward, welding can be carried out.

[0009] As a preferred embodiment of the above technical solution, a moving cavity of corresponding length is arranged on the top of the moving slide groove, a driving slider is arranged inside the moving cavity, the driving slider is fixed to the moving slider by magnetic adsorption, and a first gas injection channel and a second gas injection channel are respectively arranged at both ends of the moving cavity, the first gas injection channel and the second gas injection channel are connected to an external gas supply device through a pipeline, and air is injected into the moving cavity through the first gas injection channel or the second gas injection channel, and the driving slider is pushed by the airflow to move inside the moving cavity to provide power for the moving slider.

[0011] As a preferred embodiment of the above technical solution, a sealing piston is provided at a through-hole in the middle of the movable slider, and a first elastic block is provided between the sealing plug and the movable slider.

[0012] As a preferred embodiment of the above technical solution, the clamp assembly also includes an air injection pipe, the exhaust pipe is located on one side of the second air injection channel, the air injection pipe passes through the movable cavity and the movable slide groove, and a second baffle is arranged at the bottom of the air injection pipe.

[0015] As a preferred embodiment of the above technical solution, the two connecting frames have different lengths and are fitted to each other.

[0016] A working method of a fully automatic terminal welding device comprises the following steps:

[0017] S1, terminal clamping;

[0025] 2. The folding ring is expanded by gas injection. The two clamping pieces move toward each other as the folding ring expands to clamp the terminal in the middle. After the sealing piston closes the gas channel, the clamping piece keeps clamping the terminal for subsequent moving and welding work.

[0026] 3. The change in air pressure is used to push the piston to move so that the gas channel is opened, and the gas escaping from the gas injection pipe enters the gas channel to complete the clamping work of the clamping part.

The gas no longer enters the gas channel, thereby achieving the release of the terminal by the clamping member. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0036] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments and the accompanying drawings of the specification.

[0037] Example

[0038] Figure 1-Figure 4 A fully automatic terminal welding device, comprising:

[0039] In the placing rack diagram: 10, the placing rack diagram: 10 is arranged at the end of the vibration plate track, and the placing rack diagram: 10 is used to carry the terminals transported by the vibration plate track;

[0040] A clamp assembly, the clamp assembly comprising a clamp bottom plate 20 that reciprocates in the vertical direction, two movable slide grooves 30 of different lengths are provided at the bottom of the clamp bottom plate 20, a movable slide block 40 that reciprocates is provided inside the movable slide groove 30, and a clamping member 60 for clamping a terminal is provided at the bottom of the movable slide block 40;

[0041] After the clamp base plate 20 moves upward to the placement rack position 10, the moving slider 40 drives the clamping member 60 to move to the placement rack position 10 to clamp the terminals, and automatically resets after clamping to disperse the terminals. The different lengths of the moving slide grooves 30 are used to move the terminals at a fixed distance so that they are at the top of the two battery poles. After the clamp base plate 20 moves down, welding can be carried out.

[0042] A moving cavity 51 of corresponding length is arranged on the top of the moving slide 30, and a driving slider 52 is arranged inside the moving cavity 51. The driving slider 52 is fixed to the moving slider 40 by magnetic adsorption, and a first gas injection channel 53 and a second gas injection channel 54 are respectively arranged at both ends of the moving cavity 51. The first gas injection channel 53 and the second gas injection channel 54 are connected to an external gas supply device through a pipeline. Air is injected into the moving cavity 51 through the first gas injection channel 53 or the second gas injection channel 54, and the driving slider 52 is pushed by the airflow to move inside the moving cavity 51 to provide power for the moving slider 40.

[0043] When the battery terminals need to be welded, the external power device drives the clamp base plate 20 to move upward to the placement frame: 10 position, and then the external gas supply device injects gas into the first gas injection channel 53 through the pipeline, and the driving slider 52 moves in the moving cavity 51 under the push of the gas. Because the driving slider 52 and the moving slider 40 are magnetically adsorbed and fixed, the moving slider 40 moves inside the moving slide 30 accordingly. When the driving slider 52 moves to the position of the second gas injection channel 54, the external gas supply device stops injecting gas into the first gas injection channel 53, and the corresponding moving slider 40 moves the clamping member 60 to the placement frame. In the frame diagram: 10, the clamping member 60 then clamps the corresponding terminal. After the clamping member 60 clamps and fixes the terminal, the external gas supply device injects gas into the second gas injection channel 54 through the pipeline, and the driving slider 52 is quickly reset under the push of the gas. The moving slider 40 then drives the clamping member 60 to reset and disperse the terminals. The different lengths of the moving slide grooves 30 are used to move the terminals at a fixed distance so that they are at the top of the two battery poles, thereby automatically placing the terminals. Subsequently, the external power device drives the fixture bottom plate 20 to move downward so that the terminals are in contact with the corresponding battery poles, and a welding gun can be used to weld the two terminals at the same time.

[0044] The driving slider 52 is pushed to move back and forth in the moving cavity 51 under the pushing action of the gas. The moving slider 40 extends the clamping member 60 into the placement frame 10 along with the driving slider 52 to clamp the terminal. In addition, the moving slide grooves 30 of different lengths are used to return the terminals at a fixed distance, so that the automatically arranged terminals directly contact the corresponding battery poles after moving down, which can make the terminals more convenient and quick to adjust, thereby improving the welding efficiency of the terminals.

[0045] A working method of a fully automatic terminal welding device comprises the following steps:

[0046] S1, terminal clamping;

[0047] After the fixture bottom plate 20 moves upward to the position 10 in the placement rack, the moving slider 40 drives the clamping member 60 to move to the placement rack 10, and the two clamping members 60 clamp the corresponding terminals;

[0048] S2, terminal positioning;

[0049] The moving slider 40 drives the clamping member 60 to reset and disperse the terminals, and the terminals are moved at a fixed distance by utilizing the different lengths of the moving slide grooves 30 so that the terminals are located at the tops of the two battery poles;

[0050] S3, terminal welding;

[0051] The fixture bottom plate 20 is moved downward to make the terminals contact with the corresponding battery poles, and then a welding gun is used to weld the two terminals simultaneously.

[0052] Figure 4 and Figure 7 In the figure, the clamping member 60 includes a connecting frame 61, which is fixedly connected to the corresponding moving slider 40. A gas channel 62 is arranged inside the connecting frame 61, and the gas channel 62 is connected to the middle of the moving slider 40. Two clamping plates 63 that move toward or in opposite directions are arranged between the connecting frames 61, and a folding ring 64 is arranged between the clamping plates 63 and the corresponding mounting plates.

[0053] A sealing piston 65 is provided at a through-hole in the middle of the movable slider 40 , and a first elastic block 66 is provided between the sealing plug and the movable slider 40 .

[0054] After the sealing piston 65 is opened, the first elastic block 66 is compressed and deformed, and the gas can enter the gas channel 62 from the middle of the movable slider 40. The gas filling causes the folding ring 64 to expand and push the clamping piece 63. The two clamping pieces 63 move toward each other to clamp the terminal in the middle. After the gas injection is completed, the first elastic block 66 pushes the sealing piston 65 to reset and close the gas channel 62 to prevent the gas from escaping and causing the clamping member 60 to be unable to maintain the clamping action on the terminal. When the clamping of the terminal needs to be disconnected, the sealing piston 65 is pushed to open and no more gas is injected. The folding ring 64 can drive the clamping piece 63 to shrink and leave the terminal position.

[0055] The folding ring 64 is expanded by gas injection, and the two clamping pieces 63 move toward each other as the folding ring 64 expands to clamp the middle terminal. After the sealing piston 65 closes the gas channel 62, the clamping member 60 keeps clamping the terminal for subsequent movement and welding.

[0056] Figure 4 and Figure 5 In the figure, the fixture assembly also includes an air injection pipe 71, the exhaust pipe 73 is located on one side of the second air injection channel 54, the air injection pipe 71 passes through the movable cavity 51 and the movable slide groove 30, and a second baffle 72 is provided at the bottom of the air injection pipe 71, and the second baffle 72 is made of iron.

[0057] A pushing piston 75 is disposed inside the gas injection pipe 71 and the exhaust pipe 73 . A second elastic block 76 is disposed between the pushing piston 75 and the gas injection pipe 71 or the exhaust pipe 73 . A pushing block 77 is disposed at the bottom of the pushing piston 75 .

[0058] When the clamping member 60 is extended into the placement rack (Figure 10), the moving slider 40 pushes the second baffle 72 away from the pushing block 77 position, increasing the air flow injected into the first gas injection channel 53, and the pushing piston 75 in the gas injection tube 71 is pushed by the gradually increasing pressure to open the gas injection tube 71, and the second elastic block 76 is compressed and deformed accordingly, and the movable cavity 51 is connected to the movable slide groove 30, and the pushing piston 75 drives the pushing block 77 to move to open the sealing piston 65, and the gas continues to enter the gas channel 62 through the gas injection tube 71 so that the clamping member 60 clamps the terminal. After stopping the injection of gas, the second elastic block 76 drives the pushing piston 75 to reset and close the gas injection tube 71. When the clamping member 60 is reset, the second baffle 72 returns to the bottom of the pushing block 77 with the movement of the moving slider 40. When the air flow injected into the second gas injection channel 54 increases, the second baffle 72 blocks the bottom of the pushing block 77, and the gas injection tube 71 remains in a closed state.

[0059] The change in gas pressure is used to push the piston 75 to move so that the gas channel 62 is opened, and the gas escaping from the gas injection pipe 71 enters the gas channel 62 to complete the clamping work of the clamping member 60.

[0060] Figure 4 and Figure 6 In the embodiment, the fixture assembly further comprises an exhaust pipe 73 , which is located at one side of the first gas injection channel 53 , and both ends of the exhaust pipe 73 pass through the movable cavity 51 and the movable slide groove 30 , and a first baffle 74 is provided at the bottom of the gas injection pipe 71 .

[0061] A pushing piston 75 is disposed inside the gas injection pipe 71 and the exhaust pipe 73 . A second elastic block 76 is disposed between the pushing piston 75 and the gas injection pipe 71 or the exhaust pipe 73 . A pushing block 77 is disposed at the bottom of the pushing piston 75 .

[0062] After the clamping member 60 is reset, the sliding block 40 pushes the first baffle 74 away from the pushing block 77 position. After the terminal welding is completed, the air flow injected into the second gas injection channel 54 is increased, and the pushing piston 75 in the exhaust pipe 73 is pushed by the gradually increasing pressure to open the exhaust pipe 73, and the second elastic block 76 is compressed and deformed accordingly, and the movable cavity 51 is connected to the movable slide groove 30, and the pushing piston 75 drives the pushing block 77 to move to open the sealing piston 65, and the gas diffuses outward from the bottom of the exhaust pipe 73. Because the gas does not enter the gas channel 62, the clamping member 60 no longer clamps the terminal. After the gas injection is stopped, the second elastic block 76 drives the pushing piston 75 to reset and close the exhaust pipe 73. When the clamping member 60 extends into the placement rack (Figure 10), the first baffle 74 returns to the bottom of the pushing block 77 with the movement of the moving slider 40. When the air flow injected into the first gas injection channel 53 increases, the first baffle 74 blocks the bottom of the pushing block 77, and the exhaust pipe 73 remains closed.

[0063] The change in gas pressure is used to push the piston 75 to move so that the gas channel 62 is opened, and the gas escaping from the exhaust pipe 73 diffuses to other directions. The gas no longer enters the gas channel 62, thereby achieving the release of the terminal by the clamping member 60.

[0064] Figure 2-Figure 4 In the embodiment, the two connecting frames 61 have different lengths, and the two connecting frames 61 are fitted together.

[0065] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
