When the base plate to be welded moves to the bottom of the grabbing table, the moving rail drives the grabbing table to move horizontally with the grabbing table, and then the moving rail drives the grabbing table to sink, so that the grabbing table contacts and grabs the base plate to be welded, and moves the base plate to be welded to the bottom of the mechanical claw. The mechanical claw grabs the electronic component connected to the base plate to be welded. Driven by the moving rail, the grabbing table fits the base plate to be welded with the outer side of the electronic component. At this time, the welding wire position of the welding gun contacts the fitting part of the base plate to be welded and the electronic component. By starting the welding gun, the base plate to be welded is The electronic components are welded and fixed; the specific welding process is as follows: the welding gun spot-welds the fitting, then the mechanical claw releases the fixation of the electronic components, and then the moving rail drives the bottom plate to be welded to move horizontally as a whole, so that one side of the fitting is completely welded to ensure stable welding of the two; then the moving rail drives the grabbing table and the welded finished product to move above the second conveyor belt, and the finished product is placed above the second conveyor belt, and the finished product is transported outward through the second conveyor belt. Through this setting, the function of fully automatic welding of the bottom plate of the thermal protector and the electronic components is realized without manual assistance and operation, which greatly reduces the required human resources.

[0009] Preferably, the grabbing table includes a servo motor, the bottom output end of the servo motor is fixedly connected to a center box, the bottom of the center box is installed with an optical camera, and the bottom of the center box is fixedly connected to a suction plate capable of grabbing the base plate to be welded on one side. In order to further improve the accuracy and automation of the welding process, when the base plate to be welded moves to the bottom of the grabbing table, the placement position of the base plate to be welded is observed by the optical camera, and the center box is driven to rotate by the servo motor. At the same time, the moving rail also drives the grabbing table as a whole to move, so that the grabbing table and the base plate to be welded are aligned, and then the moving rail drives the grabbing table as a whole to sink, and the edge of the base plate to be welded is adsorbed and fixed by the suction plate, so that the same position of the base plate to be welded can be accurately grasped each time. In this way, when the base plate to be welded is moved When it moves to under the welding gun and the mechanical claw, it can ensure that each welding position is in the predetermined place, which improves the welding quality and accuracy. At the same time, the base plate to be welded on the conveyor belt can also be placed in disorder, reducing the pre-processing and placement links of the base plate to be welded; at the same time, since the servo motor can drive the center box to rotate, when the welding gun welds the electronic components and one side of the base plate to be welded, the servo motor can drive the entire center box, the base plate to be welded and the electronic components to rotate, and at the same time, cooperate with the movement of the moving rail to move the other side of the fitting place of the base plate to be welded and the electronic components close to the welding gun, so that secondary welding can be performed; the number of welding sides can be increased according to the needs of the welded parts.

After welding is completed, the movable rail will drive the finished product to move to the top of the recycling bin, and the movable rail will drive the finished product to swing at the same time. Since the electronic components are welded above the base plate to be welded, if the welding is not firm enough, the electronic components will fall off during the swinging process and fall into the recycling bin. Since the base plate to be welded is flat, the laser rangefinder at the end of the adsorption plate will emit a measuring laser. When the electronic components fall off, the measured value will change, so as to know whether the electronic components on the base plate to be welded are detached; after detachment is found, the base plate to be welded is directly put into another recycling bin.

The bottom plate 2 to be welded is moved to the bottom of the mechanical claw 9. The mechanical claw 9 grabs the electronic components connected to the bottom plate 2 to be welded. Driven by the moving rail 4, the grabbing platform 3 fits the bottom plate 2 to be welded with the outer side of the electronic components. At this time, the welding wire position of the welding gun 21 contacts the bonding position of the bottom plate 2 to be welded and the electronic components. The moving rail 4 then drives the grabbing table 3 and the welded finished product to move above the conveyor belt 2 5, places the finished product above the conveyor belt 2 5, and transports the finished product outward through the conveyor belt 2 5. Through this arrangement, the function of fully automatic welding of the thermal protector bottom plate and the electronic components is realized without manual assistance and operation, which greatly reduces the required human resources.

[0031] The grabbing platform 3 includes a servo motor 11, a central box 12 is fixedly connected to the bottom output end of the servo motor 11, an optical camera 13 is installed at the bottom of the central box 12, and a suction plate 14 capable of grabbing the bottom plate 2 to be welded is fixedly connected to one side of the bottom of the central box 12;

[0032] During operation, in order to further improve the accuracy and automation of the welding process, when the base plate 2 to be welded moves to under the grabbing platform 3, the placement position of the base plate 2 to be welded is observed by the optical camera 13, and the central box 12 is driven to rotate by the servo motor 11. At the same time, the moving rail 4 also drives the grabbing platform 3 to move as a whole, so that the grabbing platform 3 and the base plate 2 to be welded are aligned. Then, the moving rail 4 drives the grabbing platform 3 to sink as a whole, and the edge of the base plate 2 to be welded is adsorbed and fixed by the adsorption plate 14, so that the same position of the base plate 2 to be welded can be accurately grasped each time. In this way, when the base plate 2 to be welded is moved under the welding gun 21 and the mechanical claw 9, it can be ensured that the welding position each time is in the predetermined place, which improves While improving the welding quality and accuracy, the base plate 2 to be welded on the conveyor belt 1 can also be placed in disorder, reducing the pre-processing and placement steps of the base plate 2 to be welded; at the same time, since the servo motor 11 can drive the central box 12 to rotate, when the welding gun 21 welds the electronic component and one side of the base plate 2 to be welded, the servo motor 11 can drive the entire central box 12, the base plate 2 to be welded and the electronic component to rotate, and at the same time, cooperate with the movement of the moving rail 4 to move the other side of the fitting of the base plate 2 to be welded and the electronic component close to the welding gun 21, so that secondary welding can be performed; the number of welding sides can be increased according to the needs of the welded parts. Through this arrangement, a further stable welding function of the base plate 2 to be welded and the electronic components is achieved.

[0034] During operation, after welding is completed, the moving rail 4 will drive the finished product to move to the top of the recycling box 6, and the moving rail 4 will drive the finished product to swing. Since the electronic components are welded above the base plate 2 to be welded, if the welding is not strong enough, the electronic components will fall during the swinging process and fall into the recycling box 6. Since the base plate 2 to be welded is flat, the laser rangefinder 15 at the end of the adsorption plate 14 will emit a measuring laser. When the electronic components fall, the measured value will change, so as to know whether the electronic components on the base plate 2 to be welded are detached; after finding the detachment, the base plate 2 to be welded is directly placed in another recycling box 6. Through this detection setting, defective products such as cold welding can be effectively reduced.

[0035] The bottom of the central box 12 is provided with a notch, the optical camera 13 is installed at the bottom of the notch, the adsorption plate 14 is away from the notch, and the horizontal height of the adsorption plate 14 is lower than the optical camera 1;

[0036] During operation, the setting of the notch allows the optical camera 13 to be higher than the adsorption plate 14, so that when the adsorption plate 14 is attached to the bottom plate 2 to be welded, the optical camera 13 still keeps a distance from the conveyor belt 1 to reduce damage.

[0038] When working, magnetic force is generated by energizing the electromagnet, thereby adsorbing the base plate 2 to be welded, and then completing the grasping and transfer of the base plate 2 to be welded. When the base plate 2 to be welded is not made of metal that can be magnetized, suction is generated by a vacuum pump and transmitted to the adsorption hole 19 through the transmission tube 16, thereby grasping the base plate 2 to be welded, thereby realizing the function of grasping base plates 2 to be welded of various materials.

[0039] A connecting platform 17 is fixedly connected to one side of the bottom of the central box 12 near the adsorption plate 14, and a docking strip 18 is clamped at the end of the connecting platform 17. Two symmetrically arranged electric wheels 22 are installed in the middle of the adsorption plate 14. The electric wheels 22 are arranged in an elliptical shape, and the bottom of the electric wheels 22 is exposed below the adsorption plate 14;

[0040] During operation, after the base plate 2 to be welded is adsorbed on the bottom of the adsorption plate 14, the electric wheel 22 is started to rotate, and the elliptical electric wheel 22 will periodically rub the base plate 2 to be welded, thereby dragging the base plate 2 to be welded toward the connecting platform 17, so that one edge of the base plate 2 to be welded is bonded to the docking strip 18, thereby further positioning the captured base plate 2 to be welded, so that during the bonding process with the electronic components, the accuracy of the docking can be guaranteed, and the quality of the welding can also be guaranteed. At the same time, the docking strip 18 can be replaced, and docking strips 18 of different shapes can adapt to base plates 2 to be welded of different shapes.

[0041] The top surface of the conveyor belt 1 is provided with two deflection strips 7 for guiding the bottom plate 2 to be welded, and the conveyor belt 2 5 is provided with a central concave shape;

[0042] During operation, the deflection strip 7 is arranged to guide the bottom plate 2 to be welded on the conveyor belt 1 to move toward the center, so as to facilitate the grabbing process of the grabbing platform 3.

[0043] The movable rail 4 is composed of three electric slide rails, which are arranged vertically in pairs, and a horizontally arranged bracket is fixedly connected between the moving end of the vertically arranged electric slide rail and the servo motor 11;

[0044] During operation, the three electric slide rails are connected in pairs, realizing the arbitrary movement process of the grabbing platform 3 in the space. One grabbing platform 3 is waiting to grab the base plate 2 to be welded, and the other grabbing platform 3 is performing welding operations. They work in turns to improve work efficiency. The laser rangefinder 15 can detect the distance between the two in real time to ensure that they do not affect each other.

[0045] The welding gun 21 is arranged in an inclined manner, and an electric telescopic rod 20 for controlling the movement of the welding gun 21 is fixedly connected to the top of the welding gun 21, and a driving platform 10 for fixing the electric telescopic rod 20 is arranged on one side of the electric telescopic rod 20, and the driving platform 10 and the welding gun 21 are connected by a flexible metal tube;

[0046] During operation, the tilted welding gun 21 allows the welding wire to more conveniently contact the joint between the base plate 2 to be welded and the electronic component. At the same time, the electric telescopic rod 20 can control the movement of the welding gun 21, so that the welding wire of the welding gun 21 can be joined after the base plate 2 to be welded and the electronic component are joined, thereby reducing the mutual influence between the parts.

[0047] The top of the mechanical claw 9 is fixedly connected with an electric telescopic rod 8 for driving the mechanical claw 9 to move up and down. The claw body of the mechanical claw 9 is hollow, and the hollow part of the claw body is fixedly connected with an exhaust fan. The output end of the exhaust fan is connected with an exhaust pipe 23, and the outer side of the exhaust pipe 23 is connected to the outer shell of the electric telescopic rod 8.

[0048] During operation, the mechanical claw 9 is controlled to rise by shortening the electric telescopic rod 8 to obtain electronic components from above, and the electronic components are sent to the mechanical claw 9 using transportation equipment. Then the mechanical claw 9 drives the electronic components to sink and overlap with the top surface of the base plate 2 to be welded and wait for welding. The exhaust fan is started during the welding process to absorb the smoke generated during welding and transfer it outward through the exhaust pipe 23 to maintain a healthy welding environment.

[0049] During operation, the base plate 2 to be welded is placed on the conveyor belt 1, and the conveyor belt 1 is used to transport the base plate 2 to be welded. When the base plate 2 to be welded moves to the bottom of the grabbing platform 3, the moving rail 4 drives the grabbing platform 3 to move horizontally with the grabbing platform 3, and then the moving rail 4 drives the grabbing platform 3 to sink, so that the grabbing platform 3 contacts with the base plate 2 to be welded and grabs the base plate 2 to be welded, and moves the base plate 2 to the bottom of the mechanical claw 9. The mechanical claw 9 grabs the electronic components connected to the base plate 2 to be welded. Driven by the moving rail 4, the grabbing platform 3 fits the base plate 2 to be welded with the outer side of the electronic components. At this time, the welding wire position of the welding gun 21 contacts the fitting position of the base plate 2 to be welded and the electronic components. The welding process is as follows: the welding gun 21 spot welds the joint, and then the mechanical claw 9 releases the fixation of the electronic component, and then the moving rail 4 drives the whole of the welding bottom plate 2 to move horizontally, so that one side of the joint is completely welded to ensure the stable welding of the two; then the moving rail 4 drives the grabbing table 3 and the welded finished product to move above the conveyor belt 2 5, and the finished product is placed above the conveyor belt 2 5, and the finished product is transported outward through the conveyor belt 2 5. Through this setting, the function of fully automatic welding of the thermal protector bottom plate and the electronic component is realized without manual assistance and operation, which greatly reduces the required human resources;

[0050] In order to further improve the accuracy and automation of the welding process, when the base plate 2 to be welded moves to the bottom of the grabbing table 3, the placement position of the base plate 2 to be welded is observed by the optical camera 13, and the central box 12 is driven to rotate by the servo motor 11. At the same time, the moving rail 4 also drives the grabbing table 3 to move as a whole, so that the grabbing table 3 and the base plate 2 to be welded are aligned. Then the moving rail 4 drives the grabbing table 3 to sink as a whole, and the edge of the base plate 2 to be welded is adsorbed and fixed by the adsorption plate 14, so that the same position of the base plate 2 to be welded can be accurately grasped each time. In this way, when the base plate 2 to be welded is moved under the welding gun 21 and the mechanical claw 9, it can be ensured that the welding position is in the predetermined place each time, which improves the welding accuracy. While improving quality and accuracy, the base plate 2 to be welded on the conveyor belt 1 can also be placed in disorder, reducing the pre-processing and placement links of the base plate 2 to be welded; at the same time, since the servo motor 11 can drive the central box 12 to rotate, when the welding gun 21 welds the electronic component and one side of the base plate 2 to be welded, the servo motor 11 can drive the entire central box 12, the base plate 2 to be welded and the electronic component to rotate, and at the same time cooperate with the movement of the moving rail 4 to move the other side of the fitting of the base plate 2 to be welded and the electronic component close to the welding gun 21, so that secondary welding can be performed; the number of welding sides can be increased according to the needs of the welded parts, and through this setting, a further stable welding function of the base plate 2 to be welded and the electronic components is achieved;

[0051] When welding is completed, the moving rail 4 will drive the finished product to move to the top of the recycling box 6, and the moving rail 4 will drive the finished product to swing. Since the electronic components are welded on the top of the base plate 2 to be welded, if the welding is not strong enough, the electronic components will fall off during the swinging process and fall into the recycling box 6. Since the base plate 2 to be welded is flat, the laser rangefinder 15 at the end of the adsorption plate 14 will emit a measuring laser. When the electronic components fall off, the measured value will change, so as to know whether the electronic components on the base plate 2 to be welded are detached; after the detachment is found, the base plate 2 to be welded is directly put into another recycling box 6. Through this detection setting, defective products such as cold welding can be effectively reduced;

[0052] The notch groove is set so that the optical camera 13 is higher than the adsorption plate 14, so that when the adsorption plate 14 is attached to the bottom plate 2 to be welded, the optical camera 13 still keeps a distance from the conveyor belt 1 to reduce damage;

[0053] By energizing the electromagnet to generate magnetic force, the base plate 2 to be welded is adsorbed, thereby completing the grasping and transfer of the base plate 2 to be welded. When the base plate 2 to be welded is not a metal material that can be magnetized, the vacuum pump generates suction force, which is transferred to the adsorption hole 19 through the transmission tube 16, so that the base plate 2 to be welded is grasped, thereby realizing the function of grasping base plates 2 to be welded of various materials;

[0054] After the base plate 2 to be welded is adsorbed on the bottom of the adsorption plate 14, the electric wheel 22 is started to rotate, and the elliptical electric wheel 22 will periodically rub the base plate 2 to be welded, thereby dragging the base plate 2 to be welded toward the connection platform 17, so that one edge of the base plate 2 to be welded is fitted with the docking strip 18, thereby further positioning the captured base plate 2 to be welded, so that in the process of fitting with the electronic components, the accuracy of the docking can be guaranteed, and the quality of welding can also be guaranteed. At the same time, the docking strip 18 can be replaced, and docking strips 18 of different shapes can adapt to base plates 2 to be welded in different shapes;

[0055] The deflection strip 7 is provided to guide the bottom plate 2 to be welded on the conveyor belt 1 to move closer to the center, so as to facilitate the grabbing process of the grabbing platform 3;

[0056] The three electric slide rails are connected in pairs, which realizes the arbitrary movement process of the grabbing platform 3 in the space. One grabbing platform 3 is waiting to grab the bottom plate 2 to be welded, and the other grabbing platform 3 is performing welding operation. They work in turns to improve work efficiency. The laser rangefinder 15 can detect the distance between the two in real time to ensure that they do not affect each other.

[0057] The tilted welding gun 21 can make the welding wire contact the joint of the base plate 2 to be welded and the electronic component more conveniently. At the same time, the electric telescopic rod 20 can control the movement of the welding gun 21, so that the welding wire of the welding gun 21 can be joined after the base plate 2 to be welded and the electronic component are joined, thereby reducing the mutual influence between the parts;

[0058] The mechanical claw 9 is controlled to rise by shortening the electric telescopic rod 8 to obtain electronic components from above. The electronic components are sent to the mechanical claw 9 using transportation equipment. Then the mechanical claw 9 drives the electronic components to sink and overlap with the top surface of the base plate 2 to be welded and wait for welding. The exhaust fan is started during the welding process to absorb the smoke generated during welding and transfer it outward through the exhaust pipe 23 to maintain a healthy welding environment.
