Description

Technical Field

[0001] The invention relates to the field of welding equipment, and in particular to a galvanometer laser welding equipment. Background Art

[0002] Laser uses the principle of radiation excitation light amplification to produce a monochromatic, highly directional, bright light beam that is focused by transmission or reflectors to obtain a high-density power energy beam. It can be used as a heat source for welding, cutting and material surface treatment. Laser welding (LW) is an efficient and precise welding method that uses a high-energy-density laser beam as a heat source. According to the working properties of the laser generator, lasers are divided into solid, liquid, gas, semiconductor and other lasers; according to the effect of the laser on the workpiece and the output energy of the laser, laser welding can be divided into continuous laser welding and pulsed laser welding; according to the power density of the spot on the workpiece after the laser is focused, laser welding can be divided into heat transfer welding (penetration welding) and deep fusion welding (keyhole welding, perforation welding, keyhole welding).

[0003] In order to expand the application scope of laser welding, improve the quality of laser welding, increase the thickness of welded parts and avoid the limitations of simple laser welding, a new welding process has emerged: laser hybrid welding. The advantages of laser hybrid welding are: the energy utilization rate is improved, the absorption rate of the laser by the parent material is very low when it is in solid state, and the absorption rate of the laser by the laser after melting is increased to 50-100%; the penetration depth is greatly increased. Under the action of the arc, the parent material melts to form a molten pool, and the laser acts on the bottom of the arc. In addition, the absorption rate of the liquid metal to the laser beam is high, so the penetration depth of laser hybrid welding is greater than that of simple laser welding; the arc is very stable. For example, when TIG or MIG welding is used alone, the welding arc is sometimes unstable, especially under low current conditions. When the welding speed is increased to a certain value, it will cause arc drift. When laser hybrid welding is used, the plasma generated by the laser helps to stabilize the arc; improve the adaptability of the gap of the butt joint during laser welding, reduce the assembly accuracy of laser welding, and achieve high efficiency.

[0004] However, in the current technology, composite welding requires the welding head to move continuously according to the welding route, which can easily lead to many problems such as uneven welding trajectory and unstable welding quality. At the same time, there are safety hazards in manual loading. Summary of the invention

[0005] The object of the present invention is to provide a galvanometer laser welding device which can at least solve one of the above problems.

[0006] According to one aspect of the present invention, a galvanometer laser welding device is provided, comprising a body and a feeding device, a suction conveying device, a handling device, a pressing device, a dust collecting device and a galvanometer welding device which are sequentially arranged on the body along a product conveying direction, wherein the suction conveying device, the feeding device, the handling device, the pressing device and the galvanometer welding device are sequentially arranged along a conveying direction of a product to be welded, and the dust collecting device is arranged on the top of the pressing device;

[0007] The feeding device is configured to input the product to be welded;

[0008] The suction and conveying device is configured to suck the product to be welded at the feeding device and convey it to the handling device;

[0009] The handling device is configured to convey the products to be welded to the pressing device;

[0010] The pressing device is configured to press the product to be welded at the handling device;

[0011] The galvanometer welding device is configured to laser weld the products to be welded;

[0012] The dust collecting device is configured to suck away and collect welding slag and smoke generated when the galvanometer welding device is working.

[0013] The feeding device includes a belt conveyor line and a positioning mechanism. The extension direction of the belt conveyor line is perpendicular to the conveying direction of the products to be welded, and is used to carry and continuously convey the products to be welded. The positioning mechanism cooperates with the products to be welded and is used to limit the positions of the products to be welded.

[0014] Therefore, the present invention provides a galvanometer laser welding device with a completely new structure, and the working principle of the galvanometer laser welding device is as follows:

[0015] a. The products to be welded are fed into the loading station under the operation of the feeding device;

[0016] b. The suction and conveying device sucks the products to be welded from the feeding device and conveys them to the handling device;

[0017] c. The handling device transports the products to be welded to the pressing device, which is also the welding station;

[0018] d. The pressing device presses the products to be welded on the handling device;

[0019] e. The galvanometer welding device works to perform laser welding on the products to be welded;

[0020] f. The dust collection device works synchronously to absorb the welding slag and smoke generated during welding and centrally treat them;

[0021] g. Cutting the materials.

[0022] It can be seen that the galvanometer laser welding equipment of the present invention realizes the automation of loading, transportation, and galvanometer laser welding. Automatic loading and transportation can effectively overcome the safety risks of manual loading and are highly efficient. When welding a complete weld with the galvanometer, the galvanometer does not need to be moved, and the welding is completely done by the laser itself, which can overcome the problems of uneven trajectory and unstable welding quality. More importantly, a pressing device and a dust collection device are provided at the welding station. The pressing device can press down and compact the product during welding to prevent the product from softening and rebounding during welding. The dust collection device can absorb the welding slag, smoke, etc. generated during welding to avoid interference and effectively keep the working environment clean.

DETAILED DESCRIPTION

[0051] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0052] Figures 1 to 15 A galvanometer laser welding device according to an embodiment of the present invention is schematically shown.

[0053] like Figures 1 to 15 As shown, the galvanometer laser welding device includes a body 1 and a feeding device 2, a suction conveying device 3, a handling device 4, a pressing device 5, a dust collecting device 6 and a galvanometer welding device 7 arranged on the body 1. The suction conveying device 3, the feeding device 2, the handling device 4, the pressing device 5 and the galvanometer welding device 7 are arranged in sequence along the conveying direction of the product 10 to be welded, and the dust collecting device 6 is arranged on the top of the pressing device 5;

[0054] The feeding device 2 is configured to input the product 10 to be welded;

[0055] The suction and conveying device 3 is configured to suck the product 10 to be welded at the feeding device 2 and convey it to the handling device 4;

[0056] The transport device 4 is configured to transport the product 10 to be welded to the pressing device 5;

[0057] The pressing device 5 is configured to press the product 10 to be welded at the handling device 4;

[0058] The galvanometer welding device 7 is configured to perform laser welding on the product 10 to be welded;

[0059] The dust collecting device 6 is configured to absorb and collect welding slag and smoke generated when the galvanometer welding device 7 is working.

[0060] like Figure 3~4 As shown, the feeding device 2 includes a belt conveyor line 21 and a positioning mechanism 22. The extension direction of the belt conveyor line 21 is perpendicular to the conveying direction of the product 10 to be welded, and is used to carry and continuously convey the product 10 to be welded. The belt conveyor line 21 of this embodiment includes two parallel and spaced circular rotating belts, as well as a motor, a transmission gear and other structures. The positioning mechanism 22 cooperates with the product 10 to be welded, and is used to limit the position of the product 10 to be welded. The positioning mechanism 22 of this embodiment includes a mounting block, a second driving member 221 mounted on the mounting block, and a positioning block 222 connected to the driving end of the second driving member 221. The mounting block is installed between the two circular rotating belts and is located below the belt plane. The second driving member 221 is a telescopic cylinder that can drive the positioning block 222 to extend upward, thereby achieving the limitation of the product 10 to be welded.

[0061] like Figures 5 and 6As shown, the suction and conveying device 3 includes a suction mechanism 31 and a first multi-axis driving mechanism 32. The first multi-axis driving mechanism 32 is installed on the machine body 1, and the suction mechanism 31 is installed on the first multi-axis driving mechanism 32; the suction mechanism 31 includes a first mounting frame 311 and a plurality of suction components 312 mounted on the first mounting frame 311 and matched with the product 10 to be welded. The suction component 312 of this embodiment includes at least one group of suction cup groups, and each group of suction cup groups includes at least one suction cup. The first multi-axis driving mechanism 32 is a three-axis driving module, which can be specifically composed of a linear motor, a slider guide and other structures. Therefore, the multi-axis driving mechanism is used to drive the suction mechanism 31, so that automatic loading can be realized, and the loading speed is fast and the efficiency is high.

[0062] The product 10 to be welded in this embodiment is a 3C electronic product such as a battery panel with positive and negative poles.

[0063] like Figure 7 and Figure 8 As shown, the transport device 4 includes a single-axis drive mechanism 41, a linear guide 42, a slider, a third mounting plate 43 and a positioning fixture 44. The linear guide 42 is installed on the machine body 1 and is located between the feeding device 2 and the pressing device 5. The pressing device 5 is located at the end of the linear guide 42. The positioning fixture 44 is installed on the third mounting plate 43, and the third mounting plate 43 is slidably mounted on the linear guide 42 through a slider. The single-axis drive mechanism 41 is connected to the third mounting plate 43 by power. The single-axis drive mechanism 41 of this embodiment can be a linear motor. The positioning fixture 44 is provided with a plurality of limit grooves 441 that match the product 10 to be welded. There are multiple limit grooves 441, and multiple products 10 to be welded can be transported at the same time, which has high production efficiency. Therefore, the handling device 4 can realize automatic transportation of the product 10 to be welded, and its specific working principle is: after the product 10 to be welded is placed in the limiting groove 441 of the positioning fixture 44, the single-axis drive mechanism 41 works, driving the positioning fixture 44 and the product 10 to be welded thereon to slide along the linear guide rail 42 to the welding station.

[0064] like Figures 9 to 14As shown, the pressing device 5 includes a second mounting frame 51, a first driving member 52 and a pressing plate 53. The second mounting frame 51 can be movably mounted on the machine body 1, the first driving member 52 is mounted on the machine body 1 and the driving end is connected to the second mounting frame 51, and the pressing plate 53 is mounted on the upper end of the second mounting frame 51. The pressing plate 53 is located above the positioning fixture 44 and can press the product to be welded 10 on the positioning fixture 44 under the drive of the first driving member 52. The first driving member 52 of this embodiment is a telescopic cylinder. Therefore, the working principle of the pressing device 5 is as follows: under the drive of the first driving member 52, the second mounting frame 51 can be raised and lowered in the height direction, driving the pressing plate 53 to press the product to be welded 10 placed in the positioning fixture 44 downward, which can effectively prevent the product from softening and rebounding after being heated, which can not only ensure the product quality, but also facilitate the welding work.

[0065] The second mounting frame 51 includes a first mounting plate 511, a second mounting plate 512, a guide rod 513 and a sleeve 514. The first mounting plate 511 and the second mounting plate 512 are respectively mounted on the two ends of the guide rod 513 and are respectively located above and below the transport device 4. The driving end of the first driving member 52 is connected to the second mounting plate 512. The guide rod 513 is movably mounted on the body 1 through the sleeve 514. Specifically, the sleeve 514 is mounted on the upper end table panel of the body 1, and the guide rod 513 is mounted in the sleeve 514. The pressing plate 53 is mounted on the bottom of the first mounting plate 511. The pressing plate 53 is provided with welding holes 531 corresponding to the welding parts of the product 10 to be welded. The welding parts of the product 10 to be welded in this embodiment are positive and negative electrodes, that is, one product 10 to be welded needs to correspond to two welding holes 531. The first mounting plate 511 is provided with through holes 511a corresponding to the number of products 10 to be welded. The through holes 511a in this embodiment are larger than the welding holes 531. Therefore, in the initial state, there is a certain distance between the pressing plate 53 and the surface of the machine body 1, and the distance is sufficient for the transport device 4 to pass through. When the transport device 4 drives the welding product to the welding station, the first driving member 52 drives the second mounting plate 512 to move downward, and the guide rod 513 moves downward relative to the sleeve 514, thereby driving the first mounting plate 511 and the pressing plate 53 installed on the first mounting plate 511 to move downward together, pressing the product to be welded 10 to the positioning fixture 44.

[0066] The dust collecting device 6 includes a fixed seat 61, an exhaust pipe 62 and an exhaust chamber 63. The fixed seat 61, the exhaust pipe 62 and the exhaust chamber 63 are all installed on the first mounting plate 511. The exhaust chamber 63 is installed on the edge of the through hole 511a and the corresponding cover is arranged on the outer periphery of each welding hole 531. The fixed seat 61 is arranged on the side of the exhaust chamber 63 and is connected with each exhaust chamber 63. One end of the exhaust pipe 62 is connected with the fixed seat 61, and the other end is connected to the external exhaust device. Therefore, the principle of the dust collecting device 6 is as follows: during welding, the welding slag and smoke generated are collected in the exhaust chamber 63, and the external exhaust device exhausts air to suck out the welding slag and smoke through the exhaust pipe 62; the fixed seat 61 plays a gathering role and a fixing role of the exhaust pipe 62.

[0067] The pressing device 5 further comprises a metal welding block 54, which is embedded in each welding hole 531 and has a through hole 541 in the middle for the laser to pass through. Thus, the metal welding block 54 can play a role.

[0068] The bottom of the pressing plate 53 is provided with a limiting protrusion 532 which matches with the product 10 to be welded, thereby playing a role of positioning and limiting.

[0069] like Fig.15 As shown, the galvanometer welding device 7 of this embodiment includes a galvanometer welding module 71 and a second multi-axis driving mechanism 72. The second multi-axis driving mechanism 72 is installed on the body 1, and the galvanometer welding module 71 is installed on the second multi-axis driving mechanism 72. The galvanometer welding module 71 of this embodiment is composed of modules such as a galvanometer laser welding head and an optical path. The specific structure can refer to the relevant description of commercially available galvanometer welding equipment. The second multi-axis driving mechanism 72 of this embodiment is a three-axis driving module, which can be specifically composed of a linear motor, a slider guide rail and other structures. Therefore, a multi-axis driving mechanism is used to drive the galvanometer welding module 71 to achieve position adjustment of the galvanometer welding module 71, which has a wide range of applications, a high degree of automation, and is precise and efficient.

[0070] The transport device 4, the pressing device 5 and the integration device of this embodiment are all two groups, and the two groups of transport devices 4, the pressing device 5 and the integration device are symmetrically arranged on the left and right sides along the conveying direction of the products to be welded 10, with the center line of the length direction of the machine body 1 as the center. Therefore, multiple products to be welded 10 can be processed at the same time, greatly improving production efficiency.

[0071] The present invention provides a galvanometer laser welding device with a completely new structure, and the working principle of the galvanometer laser welding device is as follows:

[0072] a. Feeding: The product 10 to be welded is continuously fed into the loading station under the operation of the feeding device 2 and is limited by the positioning mechanism 22;

[0073] b. Loading: The suction and conveying device 3 sucks a plurality of products 10 to be welded from the feeding device 2 at one time and conveys them to the positioning fixture 44 of the handling device 4;

[0074] c. Transportation: The handling device 4 transports the product 10 to be welded to the bottom of the pressing plate 53 of the pressing device 5, that is, the welding station;

[0075] d. Pressing: The pressing device 5 works, driving the pressing plate 53 to press down, and pressing the product 10 to be welded in the positioning fixture 44 of the conveying device 4;

[0076] e. Welding: The galvanometer welding device 7 works to perform laser welding on the product 10 to be welded;

[0077] f. Dust collection: The dust collection device 6 works synchronously during welding to absorb the welding slag and smoke generated during welding and centrally process them;

[0078] g. Unloading: Unloading is done manually or by a robot.

[0079] The galvanometer laser welding equipment of the present invention realizes the automation of loading, transportation, and galvanometer laser welding. Automatic loading and transportation can effectively overcome the safety risks of manual loading and are highly efficient. When welding a complete weld seam, the galvanometer does not need to be moved, and the laser is completely welded by itself, which can overcome the problems of uneven trajectory and unstable welding quality. More importantly, a pressing device 5 and a dust collecting device 6 are provided at the welding station. The pressing device 5 can press down and compact the product during welding to prevent the product from softening and rebounding during welding. The dust collecting device 6 can absorb the welding slag, smoke, etc. generated during welding to avoid interference and effectively keep the working environment clean.
