Description

Technical Field

[0001] The utility model relates to a welding machine, more specifically, it relates to a battery welding machine. Background Art

[0002] Laser welding is an efficient and precise welding method that uses a high-energy-density laser beam as a heat source. It is suitable for precision welding. During laser welding, the laser radiation heats the workpiece surface, and the surface energy diffuses inward through heat conduction to melt the workpiece. Therefore, the application of laser welding technology in battery welding requires that the electrode sheet and the battery fit tightly. After the battery is injected with electrolyte and initially packaged, it needs to be welded to complete the overall package. During welding, impurities need to be prevented from entering the battery. Therefore, laser welding is used as the welding method. However, laser welding melts the workpiece at high temperature, which may over-penetrate and damage the battery casing, causing electrolyte leakage or even explosion, thereby causing harm to the environment and workers. Therefore, a battery welding machine is needed, which can prevent electrolyte leakage or explosion after over-penetration of the battery casing, which may harm the environment and workers.

[0003] In view of the above reasons, how to prevent the electrolyte from leaking or exploding after the battery casing is over-punctured, which may harm the environment and personnel, is exactly the problem considered by the present application. Utility Model Content

[0004] In view of the shortcomings of the prior art, a battery welding machine is provided, which can prevent the electrolyte from leaking or exploding after the battery shell is over-pierced, thereby preventing the environment and workers from being harmed.

[0005] To achieve the above-mentioned purpose, the following technical solution is provided: a battery welding machine, comprising a first isolation chamber, a laser welding head is installed in the first isolation chamber, the first isolation chamber is fixedly connected to an isolation plate, the isolation plate is connected to a second isolation chamber, a storage mechanism is installed in the second isolation chamber, the storage mechanism comprises a plurality of clamps for fixing batteries, a channel connecting the first isolation chamber 1 and the second isolation chamber is provided at the bottom of the isolation plate, a track is fixedly connected to the bottom of the second isolation chamber, and the track is slidably connected to a moving mechanism for driving the clamps to move back and forth between the first isolation chamber and the second isolation chamber.

[0006] In summary, the above technical solution has the following beneficial effects: the initially packaged battery can be placed in the clamping member, and the clamping member can clamp the outermost metal shell of the battery, so that the welding seam can be reduced and the subsequent laser welding is convenient. A plurality of clamping members can be arranged on the storage mechanism, and by arranging a certain clamping member at the bottom of the storage mechanism, the clamping member can be connected to the moving mechanism, and the moving mechanism can move along the track, so the moving mechanism can move the clamping member at the bottom of the storage mechanism back and forth between the first isolation chamber and the second isolation chamber alone;

[0007] When in use, the storage mechanism is first taken out from the second isolation chamber, and then a plurality of pre-processed batteries are placed in the clamping member, and the parts to be welded are exposed. The clamping member moved to the inside of the first isolation chamber is sent to the welding part of the laser welding head via the moving mechanism for welding.

[0008] When the next battery needs to be welded, the clamp is moved back to its original position by the moving mechanism, and then the storage mechanism is controlled to place another clamp in the moving mechanism. The moving mechanism can be used again to move the clamp to the welding position of the laser welding head, so that multiple welding can be performed directly inside, which can reduce the number of times the second isolation chamber is opened and improve welding efficiency.

[0009] Since batteries prone to explosion usually contain more electrolyte inside, and the batteries themselves are more fragile and expensive, an isolation plate is used to isolate the welded battery from the battery to be welded by means of the first isolation chamber and the second isolation chamber to reduce the losses caused by the explosion. Since the first isolation chamber is to be welded, the explosion-proof performance of the first isolation chamber and the isolation plate needs to be as high as possible, and they cooperate with each other to control the explosion inside the first isolation chamber. In addition, if no explosion occurs, the first isolation chamber can concentrate the leaked electrolyte to prevent the electrolyte from turbulent flow and difficult to handle and cause harm, thereby preventing the electrolyte from over-penetrating the battery casing or causing an explosion that harms the environment and personnel.

[0010] The utility model isolates the welding environment through the isolation plate, the first isolation chamber and the second isolation chamber in the instrument, and replaces the storage mechanism when the next battery needs to be welded. Since the welding operation is always inside the first isolation chamber, it can achieve the purpose of preventing the electrolyte or explosion caused by the over-penetration of the battery shell from endangering the environment and workers.

[0023] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. The same parts are represented by the same reference numerals. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the accompanying drawings, and the words "bottom surface" and "top surface", "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.

[0024] Reference Figure 1-4 As shown, a battery welding machine includes a first isolation chamber 1, a laser welding head 11 is installed in the first isolation chamber 1, the first isolation chamber 1 is fixedly connected to an isolation plate 12, the isolation plate 12 is connected to a second isolation chamber 2, a storage mechanism 3 is installed in the second isolation chamber 2, the storage mechanism 3 includes a plurality of clamps 31 for fixing batteries, a channel 13 connecting the first isolation chamber 1 and the second isolation chamber 2 is provided at the bottom of the isolation plate 12, a track 14 passing through the channel 13 and fixedly connected to the first isolation chamber 1 is fixedly connected at the bottom of the second isolation chamber 2, and the track 14 is slidably connected to a moving mechanism 4 for driving the clamps 31 to move back and forth between the first isolation chamber 1 and the second isolation chamber 2;

[0025] The preliminarily packaged battery can be placed in the clamping member 31, and the clamping member 31 can clamp the outermost metal shell of the battery, so that the welding seam can be reduced and the subsequent laser welding is convenient. A plurality of clamping members 31 can be arranged on the storage mechanism 3. By arranging a certain clamping member 31 at the bottom of the storage mechanism 3, the clamping member 31 can be connected to the moving mechanism 4, and the moving mechanism 4 can move along the track 14, so the moving mechanism 4 can move the clamping member 31 at the bottom of the storage mechanism 3 back and forth between the first isolation chamber 1 and the second isolation chamber 2 alone;

[0026] When in use, the storage mechanism 3 is first taken out from the second isolation chamber 2, and then a plurality of pre-processed batteries are placed in the clamping member 31, and the parts to be welded are exposed. The clamping member 31 moved to the inside of the first isolation chamber 1 is sent to the welding position of the laser welding head 11 via the moving mechanism 4 for welding.

[0027] When the next battery needs to be welded, the clamping member 31 is moved back to the original position by the moving mechanism 4, and then the storage mechanism 3 is controlled to place another clamping member 31 in the moving mechanism 4. The moving mechanism 4 is used again to move the clamping member 31 to the welding position of the laser welding head 11, so that multiple welding can be performed directly inside, which can reduce the number of times the second isolation chamber 2 is opened and improve welding efficiency;

[0028] Since batteries prone to explosion usually contain more electrolyte inside, and the batteries themselves are more fragile and expensive, an isolation plate 12 is used to isolate the welded battery from the battery to be welded by the first isolation chamber 1 and the second isolation chamber 2 to reduce the losses caused by the explosion. Since the first isolation chamber 1 is to be welded, the explosion-proof performance of the first isolation chamber 1 and the isolation plate 12 needs to be as high as possible, and they cooperate with each other to control the explosion inside the first isolation chamber 1. In addition, if no explosion occurs, the first isolation chamber 1 can concentrate the leaked electrolyte to prevent the electrolyte from turbulently flowing and difficult to handle and causing harm, thereby preventing the electrolyte from leaking or causing an explosion after the battery casing is over-pierced, which may harm the environment and personnel.

[0029] The utility model isolates the welding environment through the isolation plate 12, the first isolation chamber 1 and the second isolation chamber 2 in the instrument, and replaces it through the storage mechanism 3 when the next battery needs to be welded. Since the welding operation is always inside the first isolation chamber 1, it can achieve the purpose of preventing the electrolyte or the explosion caused by the over-penetration of the battery shell from endangering the environment and workers.

[0030] Furthermore, the second isolation chamber 2 includes a fixed housing 21 fixedly connected to the isolation plate 12 and a movable housing 22 slidably connected to both the isolation plate 12 and the fixed housing 21;

[0031] The storage mechanism 3 further includes a transmission shaft 32 rotatably connected to the mobile housing 22, the transmission shaft 32 is fixedly connected to a turntable 33, the turntable 33 is provided with a plurality of receiving grooves 34 for receiving the clamping member 31, the plurality of receiving grooves 34 are distributed in an annular array with the axis center line of the transmission shaft 32 as the rotation center, and the receiving grooves 34 are slidably connected to a mobile base 35 fixedly connected to the clamping member 31;

[0032] The movable base 35 is provided with a notch 351 on one side facing the transmission shaft 32, and the clamping member 31 is fixedly connected with an arc-shaped groove 352 for placing the battery on the side facing the notch 351, and the cross-sectional width of the notch 351 is smaller than the width of the widest part of the cross-sectional width of the arc-shaped groove 352;

[0033] The fixed housing 21 is also rotatably connected to a connecting shaft 211 on the side away from the first isolation chamber 1, and a first motor 212 is connected to the side of the connecting shaft 211 away from the first isolation chamber 1. A protruding piece 213 in the shape of an "I" is fixedly connected to the side of the connecting shaft 211 close to the first isolation chamber 1, and a groove 321 for inserting and accommodating the protruding piece 213 is provided on the side of the transmission shaft 32 away from the first isolation chamber 1;

[0034] In order to facilitate the placement of batteries, a movable housing 22 is provided, which drives the turntable 33 to move so that the turntable 33 can expose part of the receiving groove 34. The exposed receiving groove 34 can be switched by rotating the turntable 33, and then the battery placed in the arc groove 352 can be replaced. Due to the interference of the protruding piece 213, the side of the movable housing 22 will interfere with the protruding piece 213, so that it cannot be completely separated from the fixed housing 21, which can prevent the staff from being unable to align the groove 321 with the protruding piece 213 after the replacement is completed, thereby reducing the working efficiency.

[0035] In addition, when installing the battery, the part of the battery that needs to be welded will not be accommodated in the arc groove 352, but will be exposed from the notch 351, so that when the clamping member 31 is driven to move by the moving mechanism 4, the part of the battery that needs to be welded is always exposed vertically upward, which is convenient for subsequent welding;

[0036] Starting the first motor 212 can drive the transmission shaft 32 to rotate, and the first motor 212 is arranged on the outside of the second isolation chamber 2, and the transmission shaft 32 is arranged on the inside of the second isolation chamber 2. If the transmission shaft 32 is directly connected to the first motor 212, the fixed shell 21 needs to be additionally provided with a through hole for the transmission shaft 32 to extend out, and the through hole may connect the inside and outside of the instrument. In this way, if a battery explosion or electrolyte leakage occurs in the second isolation chamber 2, the first motor 212 will be damaged through the through hole or the safety of the surrounding environment will be endangered. Therefore, the protrusion 213 and the groove 321 are plugged in. In this way, on the one hand, after the turntable 33 rotates one circle, it will not affect the separation of the movable shell 22 and the fixed shell 21. On the other hand, the connecting shaft 211 does not need to be separated from the fixed shell 21, and only the connection between the fixed shell 21 and the movable shell 22 needs to be sealed, thereby reducing the complexity of the structure and further enhancing the isolation effect of the second isolation chamber 2 inside and outside.

[0037] Further, the moving mechanism 4 includes a threaded rod 41 rotatably connected to the fixed housing 21, a second motor 42 is connected to the side of the threaded rod 41 away from the first isolation chamber 1, a threaded sleeve 43 slidably connected to the fixed housing 21 is threadedly connected to the side of the threaded rod 41 facing the first isolation chamber 1, the threaded sleeve 43 is in a rectangular shape, and a first resistance member 44 for resisting the front side of the clamping member 31 and a second resistance member 45 for resisting the rear side of the clamping member 31 are fixedly connected above the threaded sleeve 43;

[0038] The track 14 extends to one end of the first isolation chamber 1 away from the second isolation chamber 2, and the laser welding head 11 is arranged above the track 14 and the welding point is arranged in the middle of the first isolation chamber 1;

[0039] The first abutment member 44 and the second abutment member 45 have the same width. The rotary disk 33 is provided with a plurality of through slots 331 which are provided below the corresponding receiving slots 34 and are used for the first abutment member 44 to pass through. The cross-sectional width of the through slots 331 is the same as the width of the first abutment member 44.

[0040] Starting the second motor 42 can drive the threaded rod 41 to rotate, and the threaded sleeve 43 is in a rectangular shape, so the threaded sleeve 43 cannot rotate, and the rotation of the threaded rod 41 can drive the threaded sleeve 43 to move, so the first abutment 44 can drive the clamping member 31 to enter the first isolation chamber 1, and the second abutment 45 can drive the clamping member 31 to leave the first isolation chamber 1;

[0041] When the clamping member 31 is resisted by the first resisting member 44 and moves toward the inside of the first isolation chamber 1, since the laser welding head 11 is arranged above the track 14 and the welding point is arranged in the middle of the first isolation chamber 1, it will not contact the welding point at the beginning. At this time, time can be left for checking whether the battery is leaking. Continuing to move can make the welded part of the battery be under the laser welding head 11. At this time, the laser welding head 11 starts to work and can weld the battery shell. Then the clamping member 31 continues to move to smoothly weld the battery shell. The entire operation is set inside the first isolation chamber 1. Therefore, on the one hand, dust can be isolated to prevent dust from entering the battery during welding. On the other hand, if the battery shell is over-pierced and the electrolyte leaks or an explosion occurs, the first isolation chamber 1 can isolate the internal and external environments, thereby preventing harm to the environment and staff.

[0042] Furthermore, the first isolation chamber 1 is also fixedly connected to a control mechanism electrically connected to both the first motor 212 and the second motor 42, the control mechanism is electrically connected to a display screen 15 and a plurality of buttons 16 fixedly connected to the first isolation chamber 1, and the first isolation chamber 1 is also provided with an observation window 17 for observing the interior of the first isolation chamber 1.

[0043] Furthermore, a plurality of ventilation holes 18 are provided on the top of the first isolation chamber 1 .

[0044] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
