Description

Technical Field

[0001] The present invention relates to the field of welding technology, and in particular to a welding device for battery assembly. Background Art

[0002] Assembled batteries refer to third-party batteries and high-imitation batteries that are not produced by the company and are spliced ​​together with domestic protection boards and domestic battery cells. The difference between assembled batteries and original batteries should be that the original batteries are directly produced by the equipment manufacturer or directly matched with the designated manufacturers, while assembled batteries should be other assembled batteries produced by some manufacturers in accordance with corresponding standards. When assembling the batteries, rolling mill pressure welding is usually used to achieve the pressure welding assembly of the batteries. Therefore, welding equipment is required when assembling the batteries.

[0003] At present, the welding device used in battery assembly needs to flexibly move up and down to achieve pressure welding when pressure welding the battery. However, the existing welding device cannot stably guarantee high welding precision, which makes the welding of battery assembly easy to deviate, and other functions cannot be produced during the pressure welding process, resulting in poor practicality of the welding device.

[0004] The existing welding device cannot clamp and fix the battery when it is lifted and lowered for pressure welding. It is necessary to set up a fixing mechanism to clamp the battery to ensure the stability of the battery, which makes the structure of the welding device more complicated. It is not convenient to open the battery after welding in time to realize automatic unloading. In addition, the lack of protection during unloading makes it easy for the battery to fall in multiple directions.

[0005] Since sparks or welding debris are easily generated during pressure welding of batteries, existing welding devices are unable to shield the welding area during the pressure welding process, which may easily cause accidental injuries to construction workers and pose a safety hazard.

[0006] Therefore, we propose a novel welding device for battery assembly. Summary of the invention

An L-shaped groove 22 is opened inside the device body 1, and the L-shaped groove 22 is connected to one side of the groove wall of the protective groove 8. A concave groove 23 is opened on one side of the upper end of the device body 1, and a No. 1 connecting groove 24 and a No. 2 connecting groove 25 are opened on the other side of the upper end of the device body 1.

[0045] The welding structure 6 includes a telescopic rod No. 61 and a fixed rod No. 69. One end of the telescopic rod No. 61 is fixedly connected to a movable plate 62. The movable plate 62 is located in the device frame 3 to realize lifting and lowering limit. One side of the outer surface of the movable plate 62 is fixedly connected to two semicircular plates 63.

The two semicircular plates 63 are respectively slidably connected to the device frame 3 through two semicircular grooves 41 to prevent the welding structure 6 from tilting or offsetting when it is lifted or lowered.

The two groups of spotlights 68 are set to be installed at an angle, and the pressure welding head 67 is located between the two groups of spotlights 68, which increases the visual clarity during welding and reduces the welding blind area.

The tilted No. 1 slide bar 611 is limited by the No. 1 fixed rod 69, and the end of the No. 1 slide bar 611 away from the mobile frame 64 is fixedly connected with a push plate 612. The position of the push plate 612 corresponds to the position of the welding frame 10. The push plate 612 follows the tilt of the No. 1 slide bar 611 to push the battery to realize automatic loading and unloading operations.

[0048] The use steps of the present invention are as follows: when the welding device for battery assembly is in use, when the device body 1 welds the battery, the telescopic rod 61 is controlled to extend and retract through the telescopic device 5, driving the movable plate 62 to move, and when the movable plate 62 moves, the semicircular plate 63 slides in the semicircular groove 41, so that the welding device can stably ensure the high precision of welding, and avoid the deviation of pressure welding when welding the battery. After the pressure welding is completed, the upward height of the movable plate 62 increases, which can drive the No. 1 slide bar 611 located on the outer surface of the No. 1 fixed rod 69 to rotate and tilt it, thereby driving the push plate 612 to push the battery on the welding frame 10 to realize automatic loading, so that the practicality of the welding device during pressure welding is enhanced, and the front and rear moving areas of the pressure welding head 67 belong to the welding area, and the spotlight 68 is set to be installed at an angle, so that the welding blind area of ​​the welding device is reduced and the welding accuracy is improved.

[0049] Example 2: The existing welding device cannot clamp and fix the battery when the battery is lifted and lowered for pressure welding. It is necessary to set up an additional fixing mechanism to clamp the battery to ensure the stability of the battery. This results in a more complicated structure of the welding device, which is not convenient for timely opening the battery after welding to realize automatic unloading. In addition, the lack of protection during unloading makes it easy for the battery to fall in multiple directions. This problem is solved by the following solution.

[0050] See also Figure 1 , Figure 5 and Figure 7 , combined with the embodiment, the basis is different in that the fixing structure 7 includes a connecting rod 71 and two No. 2 fixing rods 74, the outer front of the connecting rod 71 is sleeved and fixedly connected with a slide tube 72, the slide tube 72 is slidably connected to the device body 1 driven by the connecting rod 71, the slide tube 72 passes through and is slidably connected to the device body 1 through the conveying groove 2, so that the clamping stability of the clamping plate 75 is stronger, and the outer surface of the slide tube 72 is rotatably connected with No. 2 slide rods 73 on both sides, and the No. 2 slide rod 73 follows the tilt adjustment under the lifting action of the slide tube 72, and the two No. 2 slide rods 73 are fixedly connected to the ends away from the slide tube 72 with clamping plates 75, and the clamping plates 75 clamp the battery along the tilt angle.

[0051] The two No. 1 limiting plates 77 are both penetrated and slidably connected to the welding frame 10, and the two No. 1 limiting plates 77 are slidably connected to the two No. 2 sliding bars 73 through the two No. 1 sliding grooves 76 that pass through the upper and lower ends of the two No. 2 sliding bars 73. The No. 1 limiting plates 77 are used to increase the stability of the connection with the No. 1 limiting plate 77. The top of the outer surface of the connecting rod 71 is fixedly connected to two No. 1 limiting plates 77. The No. 1 limiting plates 77 are used to protect the batteries during unloading to prevent the movable batteries from tipping over in multiple directions under the thrust of the pushing plate 612, thereby falling into the non-specified area. The two No. 1 limiting plates 77 are both penetrated and slidably connected to the welding frame 10, and the two No. 1 limiting plates 77 are slidably connected to the two No. 2 sliding bars 73 through the two No. 1 sliding grooves 76.

[0052] The use steps of the present invention are as follows: when the present battery assembly welding device is in use, when adjusting the welding height, the movable plate 62 moves downward to drive the connecting rod 71 to move downward, and when moving downward, the second slide bar 73 is pulled to an inclined angle, so that the clamping plate 75 can be pushed to clamp and fix the battery, and there is no need to set up a fixing mechanism to clamp the battery. The stability of the battery can be ensured by the force of the pressure welding process. The structure is simple and compact. When the movable plate 62 moves upward, the connecting rod 71 drives the slide tube 72 to move upward, and drives the second slide bar 73 in the opposite direction, so that the clamping plate 75 opens the battery to be movable, and then the thrust of the push plate 612 makes it easy for the welding device to open the welded battery in time to realize automatic unloading, and when unloading, the slide tube 72 moves upward to drive the first limit plate 77 located in the hidden groove 101 to move upward, so that the first limit plate 77 and the second limit plate 103 are spliced, which can protect the battery from falling in multiple directions, so that the battery can fall into the specified area along the inclined surface 102, thereby increasing the stability of the welding device in unloading the battery.

[0053] Example 3: When pressure welding a battery, sparks or welding debris are likely to occur during welding. The existing welding device cannot shield the welding area during the pressure welding process, which may easily cause accidental injuries to construction workers and pose a safety hazard. The following solution is used to solve this problem.

One end of 93 is rotatably connected to a pulley 95 to reduce the pushing resistance of the device. A No. 2 slide groove 96 is opened on the top of the outer surface of the tripod 93.

The inclined surface 102 is used for the battery to fall on the inclined surface 102 under the thrust of the push plate 612, and to move along the inclined surface 102. The inclined surface 102 falls into the designated area. At this time, the No. 1 limit plate 77 protects the battery that has separated from the clamping plate 75 to prevent the battery from tipping over in multiple directions and falling out of the designated area under the action of thrust. The end of the inclined surface 102 away from the device body 1 is the designated area. Two No. 2 limit plates 103 are fixedly connected to the other side of the upper end of the welding frame 10. The No. 2 limit plate 103 has the same function as the No. 1 limit plate 77, which increases the stability of the battery during automatic loading and unloading. The positions of the two No. 2 limit plates 103 correspond to the positions of the two No. 1 limit plates 77 respectively.

[0057] The use steps of the present invention are as follows: when the welding device for battery assembly is in use, when the movable plate 62 moves downward, the third slide bar 91 is driven to tilt, thereby pushing the tripod 93 to move forward, and when moving forward, the concave baffle 97 is supported to move upward, and the concave baffle 97 is moved upward to wrap the welding area, so that the welding device can shield the welding area during the pressure welding process, thereby avoiding accidental injuries to construction personnel and reducing safety hazards. When the movable plate 62 moves upward, the tripod 93 is driven to move backward, and the concave baffle 97 is driven to fall in time to facilitate observation of the welding situation. When the tripod 93 moves, the L-shaped plate 94 is located in the L-shaped groove 22 and slides. The pulley 95 is slidably connected to the device body 1 through the L-shaped groove 22, thereby increasing the flexibility and stability of the connection between the devices. When the concave baffle 97 is supported, the balanced thrust between the fourth slide bar 98 and the spring column 99 can ensure that the concave baffle 97 moves smoothly, thereby increasing the stability of the device.
