Description

Technical Field

[0001] The utility model relates to the technical field of laser welding, in particular to a laser welding device with temperature feedback. Background Art

[0002] Laser welding uses high-energy laser pulses to locally heat a small area of ​​the material. The energy of the laser radiation diffuses into the interior of the material through heat conduction, melting the material to form a specific molten pool. It is a new type of welding method, mainly for the welding of thin-walled materials and precision parts. It can realize spot welding, butt welding, lap welding, sealing welding, etc. It has a high aspect ratio, a small weld width, a small heat-affected zone, small deformation, fast welding speed, smooth and beautiful welds, no post-welding treatment or only simple treatment, high weld quality, no pores, can be precisely controlled, small focus spot, high positioning accuracy, and easy automation. Therefore, temperature control is crucial for laser welding.

[0003] For example, a Chinese utility model patent with announcement number CN218016400U discloses a laser welding device with temperature feedback. In the above prior art, although the laser welding device with temperature feedback can accurately control the temperature of the laser focused on the circuit board so that the circuit board is always within the appropriate laser welding temperature, it is only suitable for temperature feedback of the solder joint. When it is necessary to detect the temperature around the solder joint, the temperature feedback module cannot change the angle and cannot detect the temperature around the solder joint. When it is necessary to know how much temperature will affect the area around the product solder joint, the precise temperature cannot be detected. Moreover, when laser welding is performed on products of different shapes, the temperature feedback module that cannot change the angle is likely to be blocked by the protruding part of the product, resulting in the inability to detect the temperature of the solder joint. Therefore, it is necessary to design a laser welding device that can perform temperature detection and feedback on any place where detection is required for laser welding products.

[0011] As a further improvement of the above solution, the fixing component includes first fixing columns fixedly installed on both sides of the first fixing ring, threaded blocks fixedly installed at one ends of the two first fixing columns, and threaded sleeves threadedly sleeved on each threaded block. One ends of the two first fixing columns penetrate through both sides of the first fixing block and extend to the outside thereof, and one side of each of the two threaded sleeves is in contact with the outer surface of the first fixing block.

[0012] Through the above technical solutions, when the angle and position of the infrared temperature sensor are adjusted, rotating the threaded sleeve to squeeze the surface of the first fixing block can fix the infrared temperature sensor.

[0014] Through the above technical solution, when there is no need to perform temperature detection around the welding point, the second fixing column cooperates with the extrusion plate to achieve the effect of quickly positioning the center of the welding point.

[0015] As a further improvement of the above scheme, the outer surface fixing sleeve of the infrared temperature sensor is provided with a second fixing ring, and the positioning assembly includes second fixing columns fixedly installed on both sides of the second fixing ring and two elastic extrusion plates fixedly installed inside each limiting groove, each two adjacent extrusion plates are adapted to the adjacent second fixing columns, and one end of the two second fixing columns are fixedly installed with a limiting block.

[0016] Through the above technical solution, by pushing the second fixing ring of the infrared temperature sensor and allowing the second fixing column to be stuck between the two extrusion plates, the effect of quickly positioning the center of the welding point can be achieved.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0024] Next, in combination with the accompanying drawings and specific embodiments, the present utility model will be further described. It should be noted that, on the premise of no conflict, the following-described embodiments or technical features can be arbitrarily combined to form new embodiments.

[0025] Please refer to Figure 1-Figure 3 A laser welding device with temperature feedback according to this embodiment includes a control console 1. A laser component 2 is provided on one side of the control console 1. A laser welding head 3 is installed on one side of the laser component 2. A temperature detection component for detecting the temperature of the welding position of the laser welding head 3 is provided on one side of the laser welding head 3. Fixing components for fixing the temperature detection component at any angle are provided on both sides of the temperature detection component. A positioning component for quickly positioning the center welding point of the laser welding head 3 is sleeved on the laser welding head 3.

[0026] Refer to Figure 1 and Figure 3 The temperature detection component includes an infrared temperature sensor 401 provided on one side of the laser welding head 3 and a first fixing ring 402 fixedly sleeved on the infrared temperature sensor 401. A first sliding ring 7 with a first sliding groove is fixedly sleeved on the laser welding head 3. The infrared temperature sensor 401 transmits the detected temperature to the central control system of the control console 1. A first sliding block 8 is slidably installed inside the first sliding groove. A first fixing block 9 arranged in a "C" shape is fixedly installed on one side of the first sliding block 8. The infrared temperature sensor 401 is arranged inside the first fixing block 9. The fixing component includes first fixing columns 501 fixedly installed on both sides of the first fixing ring 402, threaded blocks 502 fixedly installed at one ends of the two first fixing columns 501, and threaded sleeves 503 threadedly sleeved on each threaded block 502. One ends of the two first fixing columns 501 penetrate through both sides of the first fixing block 9 and extend to the outside. One sides of the two threaded sleeves 503 are in contact with the outer surface of the first fixing block 9. Sliding the first sliding block 8 can make the infrared temperature sensor 401 rotate around the laser welding head 3, facilitating detection at any angle. When the angle and position of the infrared temperature sensor 401 are adjusted, rotating the threaded sleeve 503 to squeeze the surface of the first fixing block 9 can fix the infrared temperature sensor 401.

[0027] Refer to Figure 1 and Figure 3A second sliding ring 10 with a second sliding groove is fixedly sleeved on the laser welding head 3, a second sliding block 11 is slidably installed inside the second sliding groove, a second fixed block 12 is fixedly installed on one side of the second sliding block 11, and limiting grooves are provided on both sides of the second fixed block 12. A second fixing ring 13 is fixedly sleeved on the outer surface of the infrared temperature sensor 401, and the positioning component includes second fixing columns 601 fixedly installed on both sides of the second fixing ring 13 and two elastic extrusion plates 602 fixedly installed inside each limiting groove, every two adjacent extrusion plates 602 are adapted to the adjacent second fixing columns 601, and one end of the two second fixing columns 601 is fixedly installed with a limiting block 14. When there is no need to detect the temperature around the welding point, the second fixing ring 13 of the infrared temperature sensor 401 is pushed to allow the second fixing column 601 to be stuck between the two extrusion plates 602, so as to achieve the effect of quickly positioning the center of the welding point.

[0028] The implementation principle of a laser welding device with temperature feedback in the embodiment of the present application is as follows: when it is necessary to detect the temperature around the welding point, slide the first sliding block 8 and move around the circumferential surface of the laser welding head 3. The sliding of the first sliding block 8 and the first sliding groove is stuck after all, and needs to be rotated and adjusted by manpower. The movement and vibration of the machine cannot make the first sliding block 8 move by itself. After finding the position, the angle of the infrared temperature sensor 401 is changed by rotating the first fixed column 501. After the position and angle of the infrared temperature sensor 401 are adjusted, the threaded sleeve 503 is rotated to cooperate with the threaded block 502 to squeeze the two sides of the first fixed block 9, so that the infrared temperature sensor 401 has a fixing effect. The product needs to be fixed. This method can be used to adjust the angle position for temperature detection at any point. The infrared temperature sensor 401 will transmit the detected temperature to the central control system of the console 1. When there is no need to detect the temperature at positions other than the welding points, it is only necessary to loosen the threaded sleeve 503, rotate the second sliding block 11 to the position corresponding to the infrared temperature sensor 401, and push the second fixing ring 13 to clamp the second fixing column 601 between the two extrusion plates 602. The infrared temperature sensor 401 can be fixed at an angle. This angle is the center of the welding point set in advance, so that the center point can be quickly located. The center point is also the position with the most detection, which can reduce the trouble of the staff's work.

[0029] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
