Description

Technical Field

[0001] This utility model relates to the technical field of welding equipment, and in particular to welding equipment for batteries and PCM boards. Background Technology

[0002] A crucial step in the production of existing steel-cased pouch batteries involves welding the PCM board to the battery tabs. However, current laser welding processes for the steel-cased pouch battery and PCM board involve manually placing the PCM board into the placement slot of a battery fixture before welding it to the battery tabs. This manual process is inefficient, lacks reliable positioning, reduces PCM welding precision, leads to inconsistent production output, and ultimately compromises product quality.

[0003] To overcome the above-mentioned shortcomings, welding equipment with automatic feeding of battery PCM has appeared on the market, but it still has the shortcoming that its production efficiency cannot meet the actual needs.

[0004] Therefore, there is an urgent need to provide welding equipment for batteries and PCM boards to overcome the above-mentioned defects. Summary of the Invention

[0005] The main purpose of this invention is to provide welding equipment for batteries and PCM boards, which effectively improves production efficiency and quality.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: The battery-PCM board welding equipment includes: a fixed frame; a PCM loading and positioning and carrier positioning interaction mechanism mounted on the track module of the fixed frame; a battery front-facing photo and scanning binding mechanism horizontally suspended above the track module, which uses a CCD to capture the battery's front position, confirms the battery's positional deviation on the carrier, and scans the carrier's QR code for binding; a battery positive and negative electrode photo component suspended above the track module to acquire the battery's positive and negative electrode positions; a PCM loading gripper mechanism mounted on the fixed frame that, based on the data from the battery positive and negative electrode photo component, places the PCM board's positive and negative electrode pads onto the battery's positive and negative electrodes; a welding gripper mechanism suspended above the track module that, based on the data from the battery positive and negative electrode photo component, corrects the welding gripper position using the X and Y axes and presses the PCM board's positive and negative electrode pads onto the battery's positive and negative electrodes; and a PCM welding mechanism located beside the welding gripper mechanism that, based on a laser ranging component, laser-connects the PCM board's positive and negative electrode pads to the battery's positive and negative electrodes for corresponding welding.

[0007] Preferably, the track module includes at least two tracks, each track is equipped with a corresponding PCM loading and positioning and carrier positioning interaction mechanism, and the two tracks run alternately.

[0008] Preferably, each of the tracks is parallel and installed along the Y-axis, and the X-axis slide rails of the battery front-facing photographing and scanning binding mechanism, the welding claw mechanism, and the PCM feeding claw mechanism are all suspended above each of the tracks.

[0009] Preferably, the Z-axis module of the PCM welding mechanism is located between the welding gripper mechanism and the PCM loading gripper mechanism, the welding body is mounted on the Z-axis module, and the laser ranging component is mounted on one side of the welding body.

[0010] Preferably, the welding gripper mechanism includes: an X-axis module mounted on the fixed frame, a set of Y-axis modules slidably mounted on the X-axis module, welding grippers respectively mounted on the Y-axis modules, and a slag cleaning module mounted on one side of the welding grippers for cleaning welding slag.

[0016] This utility model discloses a battery and PCM board welding equipment. The PCM board and carrier are manually placed in the PCM loading and positioning interaction mechanism. A track module sequentially transports the PCM loading and positioning interaction mechanism to the battery front-facing photographing and scanning binding mechanism. The mechanism photographs the battery's front position, confirms the battery's positional deviation on the carrier, and scans the QR code on the carrier for binding. The PCM loading gripper mechanism places the positive and negative electrode pads of the PCM board onto the positive and negative electrodes of the battery. The welding gripper mechanism corrects the position of the welding gripper and presses the pads firmly using a battery positive and negative electrode position photographing component.

[0027] Please see Figures 1 to 4The battery-PCM board welding equipment of this embodiment is characterized by comprising: a fixed frame 1; a PCM loading, positioning, and carrier positioning interaction mechanism 2 disposed on the track module A of the fixed frame 1; a battery front-facing photographing and scanning binding mechanism 3 laterally suspended above the track module A, which uses a CCD to photograph the front position of the battery, confirms the battery's positional deviation on the carrier, and scans the carrier's QR code for binding; a battery positive and negative electrode photographing component 4 suspended above the track module A to obtain the positions of the battery's positive and negative electrodes; and a PCM board positive and negative electrode pads placed on the battery's positive and negative electrodes using the data from the battery positive and negative electrode photographing component 4, disposed on the fixed frame 1. The system includes: a PCM loading gripper mechanism 5 suspended above the track module A; a welding gripper mechanism 6 that uses data from the battery positive and negative electrode photography component 4 to correct the position of the welding gripper along the X and Y axes and presses the positive and negative electrode pads of the PCM board to the positive and negative electrodes of the battery; a PCM welding mechanism 7 located beside the welding gripper mechanism 6 that uses the laser ranging component 73 to weld the positive and negative electrode pads of the PCM board to the positive and negative electrodes of the battery using laser corresponding welding; a PCM tray 8 mounted on the fixed frame 1 and located beside the track module A and the battery front-facing photography and scanning binding mechanism 3; and a recycling box 9 mounted on the fixed frame 1 for recycling waste. It should be noted that a controller is installed on the fixed frame 1. The controller is communicatively connected to the PCM loading and positioning and carrier positioning interaction mechanism 2, the battery front-facing photographing and scanning binding mechanism 3, the battery positive and negative electrode photographing component 4, the PCM loading gripper mechanism 5, the welding clamping claw mechanism 6, and the PCM welding mechanism 7. Based on the received information, the controller issues corresponding instructions to the mechanisms / components at the corresponding production stations. The specific control method is based on existing technology and is therefore not described in detail here. During production, the material on the PCM tray 8 is manually placed onto the PCM loading and positioning and carrier positioning interaction mechanism 2 for positioning.

[0028] In a preferred embodiment, the track module A includes at least two tracks, each equipped with a corresponding PCM loading and positioning and carrier positioning interaction mechanism 2. The two tracks operate alternately. Specifically, each track is parallel and mounted along the Y-axis. The X-axis slide rails of the battery front-facing photographing and scanning binding mechanism 3, the welding claw mechanism 6, and the PCM loading gripper mechanism 5 are all suspended above each track. The PCM loading and positioning and carrier positioning interaction mechanism 2 moves along the tracks, sequentially moving to the corresponding production station. In this embodiment, the two tracks operate alternately, effectively improving production efficiency.

[0029] In a preferred embodiment, the Z-axis module 71 of the PCM welding mechanism 7 is located between the welding gripper mechanism 6 and the PCM loading gripper mechanism 5. The welding body 72 is mounted on the Z-axis module 71, and the laser ranging component 73 is mounted on one side of the welding body 73. Specifically, the laser ranging component 73 uses a laser ranging sensor to detect the height of the positive and negative terminals of the battery and transmits the detection data to the Z-axis module 71 for correcting the welding position of the welding body 73.

[0030] In this embodiment, the imaging body of the battery positive and negative electrode imaging component 4 is mounted on the X-axis slide rail of the battery positive and negative electrode imaging component 4. The X-axis slide rail is located above each of the tracks. The imaging body slides to the corresponding track according to the actual production situation and obtains the position of the battery positive and negative electrodes by CCD imaging. The PCM loading gripper mechanism 5 clamps the PCM board from the PCM positioning platform of the PCM loading positioning and carrier positioning interaction mechanism 2. After PCM positioning CCD imaging, the positive and negative electrode pads of the PCM board are placed on the positive and negative electrodes of the battery according to the data of the battery positive and negative electrode imaging component 4.

[0031] The welding gripper mechanism 6 in this embodiment includes: an X-axis module 61 mounted on the fixed frame 1; a set of Y-axis modules 62 slidably mounted on the X-axis module 61; welding grippers 63 respectively mounted on the Y-axis modules 62; and a slag cleaning module 64 mounted on one side of the welding grippers 63 for cleaning welding slag. Specifically, the slag cleaning module 64 includes: a brush a2 driven by a drive module a1 and mounted on one side of the welding grippers 63 for rotating and cleaning welding slag on the welding grippers 63; and a vacuum extraction pipe a3 connected at one end to a vacuum generator and penetrating through a welding slag recovery plate b1 and located on one side of the welding grippers 63. Specifically, the X-axis module 61 and the Y-axis module 62 adjust the position of the welding claw 63 according to the data of the battery positive and negative electrode imaging component 4, and drive the cylinder to drive the welding claw to press the welding pad. After the PCM welding mechanism 7 performs the welding operation, the drive module a1 drives the brush a3 to rotate and clean the welding slag on the welding claw 63. Simultaneously, the vacuum generator draws a vacuum and removes the welding slag that falls onto the welding slag recovery plate b1 during the cleaning process through the vacuum extraction pipe a3, thereby avoiding the influence of welding slag on the welding quality and further improving welding efficiency and welding quality.

[0032] As can be seen from the above description, the structural design of this utility model effectively improves production efficiency while promptly cleaning welding slag, thus avoiding the impact of welding slag on production efficiency and quality.
