Description

Technical Field

[0001] The present invention relates to the technical field of laser spot welding machines, and in particular to a laser spot welding machine for mold processing. Background Art

[0002] As modern manufacturing continues to demand more precision machining, the demand for welding technology in the mold processing field is also increasing. Laser spot welding technology, as an efficient and precise welding method, is widely used in the connection and repair of metal materials. Traditional mold welding methods often rely on mechanical clamping and manual adjustment, resulting in cumbersome operations. The welding quality is significantly affected by human factors. In addition, in hot working environments, welders are exposed to high temperatures, strong light, and exhaust gases, which can easily cause physical harm.

[0003] Currently, there are some automated laser spot welding equipment on the market. These devices use automatic control systems to achieve precise control of the welding position, thereby improving welding quality and production efficiency. However, existing equipment still has some shortcomings. For example, most existing welding equipment does not have integrated shielding gas injection and exhaust gas treatment functions. If these exhaust gases are not effectively treated, they will not only threaten the health of operators but also pollute the environment. At the same time, the strong light, ultraviolet light, and infrared rays generated during welding can easily cause visual damage to operators during the welding process, especially when looking directly at the weld point. The risk is greater if protective measures are not taken. Summary of the Invention

At the same time, strong light, ultraviolet rays and infrared rays are generated during welding, and the operators are prone to visual damage during the welding process, especially when looking directly at the welding point.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0065] Example 1

[0066] like Figure 1~Figure 2 As shown, this embodiment proposes:

[0067] A laser spot welding machine for mold processing, comprising:

[0068] A workbench 1 is provided with a mounting frame 2 fixed to the rear side of the top wall of the workbench 1, a No. 1 electric slide rail 3 is fixed to the top wall of the mounting frame 2, a vertical plate 4 is fixed to the top wall of the slider of the No. 1 electric slide rail 3, a No. 2 electric slide rail 5 is fixed to the side wall of the vertical plate 4, a crossbeam 6 is fixed to the side wall of the slider of the No. 2 electric slide rail 5, a laser spot welding machine body 7 is fixed to the front end of the crossbeam 6, a protective cover 8 is provided on the outer side of the welding head of the laser spot welding machine body 7, four universal wheels 15 are symmetrically installed on the bottom wall of the workbench 1, and liftable support legs 16 are symmetrically installed on the bottom wall of the workbench 1;

[0069] The gas jet collecting assembly 9 is installed on the outside of the protective cover 8. The gas jet collecting assembly 9 is used to spray protective gas to the welding position of the laser spot welding machine body 7 and collect the exhaust gas generated by welding;

[0070] Eye protection assembly 10, the eye protection assembly 10 is fixed to the front side of the laser spot welding machine body 7;

[0071] A translation lifting assembly 11 is fixed to the front side of the top wall of the workbench 1, and a clamping assembly 12 is installed on the top of the translation lifting assembly 11 through a rotating assembly 13;

[0072] The purification component 14 is installed inside the workbench 1 and is connected to the air jet collection component 9 .

[0073] In this embodiment, the laser spot welding machine body 7 is driven to move left and right and to lift by the No. 1 electric slide 3 and the No. 2 electric slide 5, so that the laser spot welding machine body 7 can perform welding operations on the corresponding positions of the mold. The universal wheels 15 can facilitate the movement of the device. The liftable support legs 16 can prop up the device when the device does not need to be moved to ensure that the position of the device is fixed. The jet gas collection component 9 is used to cooperate with the protective cover to spray protective gas to the welding position of the laser spot welding machine body 7 to ensure the welding quality and collect the exhaust gas generated by welding to avoid the operator from inhaling the exhaust gas and causing physical damage. Injury, the eye protection component 10 is used to block the welding position of the laser spot welding machine body 7, so that the operator can observe the welding position and stop the machine in time when there is a problem with the welding, avoiding damage to the operator's eyesight caused by looking directly at the welding position. The translation and lifting component 11 is used to control the forward and backward and upward movement of the clamping component 12. In conjunction with the No. 1 electric slide 3 and the No. 2 electric slide 5 and the rotating component 13, it can realize all-round spot welding operation on the welding surface of the mold. The rotating component 13 is able to drive the clamping component 12 to rotate, and then drive the mold to rotate, so that the laser spot welding machine body 7 can weld the specified position of the mold. The clamping component 12 is convenient for clamping and fixing the mold to be processed, and the purification component 14 is able to purify the exhaust gas generated by welding to avoid harmful substances contained in the exhaust gas from endangering human health and the environment.

[0074] Example 2

[0075] like Figures 3 to 7 As shown, based on the same concept as the above embodiment 1, this embodiment further proposes:

[0076] The air jet collection assembly 9 includes an air intake mechanism 91, which is mounted on the side wall of the protective cover 8, and an air collection cover 92 is fixed to the bottom wall of the air intake mechanism 91;

[0077] Both sides of the gas collecting hood 92 are fixedly connected with vertical pipes 93;

[0078] The top of the two vertical pipes 93 are fixed with a suction mechanism 94, and the rear sides of the tops of the two vertical pipes 93 are fixedly connected to the same air outlet tee pipe 97;

[0079] The bottom end of the air outlet three-way pipe 97 is connected to the purification component 14 through a metal hose.

[0080] The air intake mechanism 91 includes an outer ring pipe 911 , which is fixed to the outer wall of the protective cover 8 , and an inner ring pipe 912 is fixed to the inner wall of the outer ring pipe 911 via a plurality of connecting pipes 913 ;

[0081] The inner ring tube 912 is fixed on the inner side wall of the protective cover 8, and a plurality of nozzles 914 are symmetrically fixedly connected to the bottom wall of the inner ring tube 912.

[0082] The air extraction mechanism 94 includes a housing 941 , which is fixed to the top wall of the vertical pipe 93 , and a vertical shaft 942 is rotatably mounted on the bottom wall of the housing 941 ;

[0083] The top of the vertical shaft 942 passes through the bottom wall of the housing 941 through a leak-proof bearing and extends into the housing 941. The vertical shaft 942 is located in the housing 941 and has blades 943 symmetrically fixed on the shaft. The bottom of the vertical shaft 942 extends into the vertical tube 93. The bottom end of the vertical shaft 942 is fixed with an exhaust fan blade 944.

[0084] One side of the housing 941 is fixedly connected to an air intake tee 95, and the other side of the housing 941 is connected to the interior of the outer ring pipe 911 through a conduit 96;

[0085] The rear end of the air inlet tee pipe 95 is connected to an external protective gas tank through a metal hose.

[0086] The eye protection assembly 10 includes an L-shaped bracket 101, which is fixed to the front wall of the laser spot welding machine body 7. The bottom end of the bracket 101 is fixed with an arc-shaped mounting frame 102;

[0087] A light shielding mirror 103 is installed in the mounting frame 102 .

[0088] In this embodiment, the gas jet collection assembly 9 is used to cooperate with the protective cover to spray shielding gas at the welding position of the laser spot welding machine body 7, thereby ensuring welding quality and collecting exhaust gas generated by welding to prevent the operator from inhaling exhaust gas and causing physical damage. During the electric welding process, shielding gas (such as carbon dioxide, argon, etc.) is continuously introduced into the housing 941 through the air inlet tee 95 from an external shielding gas tank. After entering the housing 941, the high-speed airflow impacts the blades 943, thereby driving the vertical shaft 942 to rotate. The shielding gas then enters the outer ring pipe 911 through the conduit 96, enters the inner ring pipe 912 through the connecting pipe 913, and is ejected through the nozzle 914, forming a shielding gas curtain at the spot welding position to ensure welding quality. At the same time, the rotation of the vertical shaft 942 drives the exhaust fan blades 944 to rotate, drawing the exhaust gas generated during the welding process into the vertical pipe 93 and introducing it into the purification assembly 14 through the air outlet tee 97 for purification.

[0089] The sunshade 103 provided in the eye protection assembly 10 is a fixed dark glass or an automatically dimming liquid crystal lens, which can effectively filter the strong light, ultraviolet rays, infrared rays, etc. generated during the welding process, making it convenient for the operator to observe the welding position and to stop the machine in time when there is a problem with the welding.

[0090] Example 3

[0091] like Figures 8 and 9 As shown, based on the same concept as the above embodiment 1, this embodiment further proposes:

[0092] The translation and lifting assembly 11 includes a U-shaped seat 111, a screw 112 is rotatably installed between the inner side walls of the U-shaped seat 111, a No. 1 motor 113 is fixed to the front side wall of the U-shaped seat 111, and a guide rail 114 is fixed to the bottom wall of the inner cavity of the U-shaped seat 111;

[0093] A matching sliding block 115 is slidably mounted on the top of the guide rail 114;

[0094] A mounting block 116 is fixed to the top wall of the sliding block 115;

[0095] A horizontal plate 1110 is installed above the mounting block 116;

[0096] The bottom wall of the horizontal plate 1110 is connected to the top of the mounting block 116 via a telescopic rod 117;

[0097] A horizontal shaft 118 is rotatably mounted in the mounting block 116 , and a driving motor for driving the horizontal shaft 118 to rotate is mounted in the mounting block 116 ;

[0098] Eccentric disks 119 are fixed to both ends of the horizontal shaft 118 , and the top of the eccentric disk 119 is in contact with the bottom wall of the horizontal plate 1110 .

[0099] The clamping assembly 12 includes a U-shaped plate 121 , and a U-shaped frame 122 is slidably passed through both sides of the U-shaped plate 121 ;

[0100] A U-shaped frame 122 is located at one end of the U-shaped plate 121 and is fixed with a clamping plate 123. A threaded knob 124 is screwed through the side wall of the U-shaped frame 122.

[0101] One end of the threaded knob 124 is rotatably mounted on the side wall of the U-shaped plate 121;

[0102] A triangular groove 125 is defined at the clamping end of the clamping plate 123 .

[0103] The rotating assembly 13 includes a mounting shaft 131 and a second motor 134 , and a worm gear 132 is fixed to the shaft of the mounting shaft 131 ;

[0104] The worm wheel 132 is meshingly connected with a worm 133;

[0105] One end of the worm 133 is fixedly connected to the power shaft of the second motor 134 .

[0106] A cavity 17 and a motor slot 18 are provided in the horizontal plate 1110. The mounting shaft 131 and the worm 133 are both rotatably mounted in the cavity 17. The second motor 134 is fixed in the motor slot 18. The top end of the mounting shaft 131 passes through the top wall of the cavity 17 through a bearing and is fixedly connected to the center position of the bottom wall of the U-shaped plate 121. The power shaft of the second motor 134 passes through the side wall of the cavity 17 through a bearing and is fixedly connected to one end of the worm 133.

[0107] In this embodiment, the translation and lifting assembly 11 is used to control the forward and backward and upward and downward movement of the clamping assembly 12, and cooperates with the No. 1 electric slide 3 and the No. 2 electric slide 5 and the rotating assembly 13 to realize the all-round spot welding operation of the welding surface of the mold. When using the translation and lifting assembly 11, the No. 1 motor 113 is controlled to work, and the No. 1 motor 113 drives the screw 112 to rotate. During the rotation of the screw 112, the mounting block 116 is driven to move forward and backward along the guide rail 114. When it is necessary to control the upper clamping assembly 12 to move up and down, the driving motor is controlled to drive the horizontal shaft 118 to rotate. During the rotation of the horizontal shaft 118, the eccentric disk 119 is driven to rotate. The horizontal plate 1110 is attached to the surface of the eccentric disk 119 under the action of gravity. As the eccentric disk 119 rotates, the horizontal plate 1110 will move up and down, thereby controlling the clamping assembly 12 to move up and down.

[0108] The rotating assembly 13 drives the clamping assembly 12, which in turn drives the mold, facilitating the laser spot welding machine body 7 to weld the designated location on the mold. To control the rotation of the clamping assembly 12, the second motor 134 is activated. This motor 134, via the worm 133 and worm gear 132, drives the mounting shaft 131, which in turn drives the clamping assembly 12 above it.

[0109] The clamping assembly 12 facilitates the clamping and securing of the mold to be processed. To clamp the mold, place the mold with its welding surface facing upward on the top wall of the U-shaped plate 121. The threaded knob 124 is then rotated. This rotation drives the U-shaped frame 122 toward the inside of the U-shaped plate 121, allowing the two clamping plates 123 to clamp the side walls of the mold. The triangular grooves 125 on the clamping plates 123 can also clamp cylindrical molds.

[0110] Example 4

[0111] like Figures 10 to 12 As shown, based on the same concept as the above embodiment 1, this embodiment further proposes:

[0112] The purification component 14 includes a housing 141 , one end of the housing 141 is fixedly connected to an air inlet pipe 142 , and the other end of the housing 141 is fixedly connected to an air outlet pipe 143 ;

[0113] The air inlet pipe 142 is connected to the bottom end of the air outlet tee pipe 97 through a metal hose, and the air outlet pipe 143 is connected to the external environment;

[0114] A cover plate 144 is mounted on the top wall of the housing 141 via a buckle 145 , a partition plate 1412 is fixed to the inner wall of the housing 141 , and a filter plate 1411 is fixed on the partition plate 1412 ;

[0115] A collection frame 147 is fixed to the left side of the bottom wall of the cover plate 144 via a connecting rod 146, and a mounting base 148 is fixed to the right side of the top wall of the cover plate 144;

[0116] One side of the collection frame 147 is in contact with the partition 1412, and the top wall of the collection frame 147 is inclined;

[0117] The side wall of the mounting seat 148 is provided with a mounting groove 19, in which a filter element 149 is installed. A threaded cover 1410 is screwed to the left end of the mounting groove 19.

[0118] A through slot 20 is formed on the side wall of the threaded cover 1410 at positions corresponding to the filter plate 1411 and the filter element 149 .

[0119] In this embodiment, the purification assembly 14 is provided to purify the exhaust gas generated by welding, preventing harmful substances contained in the exhaust gas from endangering human health and the environment. After the exhaust gas enters the housing 141 through the air inlet pipe 142, it will first be initially filtered by the filter plate 1411 to remove large particulate matter in the exhaust gas. It will then undergo a secondary process through the filter element 149 to recover harmful gases in the exhaust gas. The type of filter element 149 can be selected according to the exhaust gas generated by different welding materials. The threaded cover 1410 is provided to cooperate with the mounting groove 19 to facilitate the removal and replacement of the filter element 149. At the same time, when the cover plate 144 is pulled upward during the replacement of the filter element 149, the side wall of the collection frame 147 can scrape off impurities accumulated on the filter plate 1411.
