Description

Technical Field

[0001] The utility model relates to the technical field of welding, in particular to a laser welding machine with CCD detection. Background Art

[0002] CCD refers to charge coupled device, which is an image sensor widely used in machine vision and image acquisition systems. It can not only provide high-precision image data, but also realize the automation and intelligence of the welding process, provide high-precision image data, and ensure the accuracy and reliability of welding. Laser welding machine is an advanced welding equipment that uses high-energy laser pulses to locally heat the surface of the welding material. It is a thermal processing process that converts the laser beam into a high-energy heat source to melt and weld the workpiece surface.

[0003] After searching, the laser welding machine disclosed in the Chinese patent with application number CN202222188337.2 is aimed at the laser welding of aluminum shell batteries. The tolerance of the aluminum shell batteries themselves is relatively large, and there is a cumulative tolerance in the stacking of aluminum shell batteries. The original technology is to weld through pre-set coordinates. The tolerance of each battery is inconsistent, and there is a risk of welding deviation during welding; at the same time, there is a risk of batteries being placed upside down in the battery stack, and welding after the batteries are placed upside down is prone to fire. Therefore, a three-axis drive mechanism and a visual mechanism are provided, which can accurately visually position the battery pack during welding to avoid welding deviation. At the same time, the visual mechanism can detect the positive and negative pole directions of the battery to avoid welding of the upside-down batteries.

[0004] During the use of the above-mentioned laser welding machine, since the CCD camera is fixedly installed on the laser welding machine, when the laser welding machine is in use, the CCD camera may be damaged due to long-term use and debris flying, thereby requiring the CCD camera to be repaired. The above-mentioned CCD camera is relatively complicated to fix and is not convenient for disassembly, which makes the disassembly of the CCD camera waste working time and delay the work progress, thereby easily reducing work efficiency.

A fixing plate 14 is fixedly connected to the top of the CCD detection machine body 13. A bolt 15 is threadedly connected to the right end of the fixing plate 14. The square groove 4 is engaged with the rear end of the fixing plate 14, thereby improving the installation stability of the CCD detection machine body 13. The bidirectional screw rod 6 is conducive to driving the two clamping plates 7 to move closer to and away from each other. The slide groove 8 is convenient for limiting the moving clamping plate 7, thereby improving the stability of the movement of the clamping plate 7. The spring 10 and the pushing block 11 are convenient for improving the tightness of the fixing plate 14 installed in the square groove 4.

[0032] As attached Figure 2As shown, a hydraulic cylinder 16 is fixedly installed at the right end of the processing table 1, and a connecting rod 17 is fixedly connected to the output end of the hydraulic cylinder 16, and a movable plate 18 is fixedly connected to the other end of the connecting rod 17. The output end of the hydraulic cylinder 16 drives the movement of the connecting rod 17 and the movable plate 18, so that the cleaning brush 26 can be adjusted forward and backward according to the position of the workpiece to be welded.

[0033] As attached Figure 1 As shown, two limit grooves 19 are provided inside the movable plate 18, and a connecting plate 20 is slidably connected inside the two limit grooves 19. The right end of the connecting plate 20 is threadedly connected to a threaded rod 21, and the bottom end of the threaded rod 21 is rotatably connected to the bottom end of the movable plate 18.

[0035] Working principle: When the laser welding head 3 needs to be disassembled, first tighten the bolt 15 to disengage the bolt 15 from the right side of the fixing plate 14, so that the fixing plate 14 can be released from the limit, and then turn the knob 12 to facilitate the knob 12 to drive the bidirectional screw 6 to rotate, so that when the bidirectional screw 6 rotates, the clamping plates 7 at both ends are driven to move away from each other, so that the clamping plates 7 on both sides are away from the two sides of the CCD detection machine body 13, and then the CCD detection machine body 13 is taken and moved upward to facilitate the fixing plate 14 to disengage from the inside of the square groove 4, so as to facilitate the disassembly of the CCD detection machine body 13, which is conducive to timely maintenance of the CCD detection machine body 13. The operation is reversed during installation. When the workpiece is placed on the surface of the processing table 1 for welding and the dust on the workpiece surface needs to be cleaned, the hydraulic cylinder 16 is first opened according to the position of the workpiece, and the extension of the output end of the hydraulic cylinder 16 is extended. , which is convenient for driving the connecting rod 17 to move, thereby pushing the movable plate 18 to move forward and backward on the right end of the processing table 1, thereby indirectly driving the front and rear position of the cleaning brush 26 to be adjusted according to the position of the workpiece, and when the height needs to be adjusted, the threaded rod 21 is rotated so that the threaded rod 21 drives the connecting plate 20 to slide inside the limiting groove 19 under the action of the thread, thereby facilitating the connecting plate 20 to move up and down, which is beneficial to indirectly driving the height position of the cleaning brush 26 to be adjusted. After the adjustment, the motor 22 is turned on, and the rotation of the output end of the motor 22 drives the eccentric wheel 1 23 to rotate, so that when the eccentric wheel 1 23 rotates, the rotating rod 24 is driven to rotate in the direction of the eccentric wheel 1 23, and then the eccentric wheel 25 is pulled to rotate, so that when the eccentric wheel 25 rotates, it drives the cleaning brush 26 to rotate and clean the surface of the workpiece, which is beneficial to improve the cleaning quality.
