[0029] Embodiment

[0030] As Figures 1-3 shown, a spark-proof device for a welding robot proposed by the present utility model includes a welding base 1. A welding head 3 is provided at the bottom of the welding base 1. It further includes a mounting base 2 which is fixedly installed on the outer side of the bottom of the welding base 1. A protective plate 4 is movably installed at the bottom of the mounting base 2. A flame retardant coating is applied to one side of the protective plate 4 close to the welding head 3, which further improves the protection effect of the protective plate 4 and at the same time increases the service life of the protective plate 4.

[0031] Wherein, an installation groove 201 for installing the protective plate 4 is formed at the bottom of the mounting base 2. A plurality of groups of protective plates 4 are provided and are arranged in a ring in the installation groove 201. A plurality of pressing plates 5 for disassembling the protective plate 4 are provided on the outer side of the mounting base 2.

[0032] In addition, a rectangular box 14 is fixedly installed in the installation groove 201. A moving plate 16 is slidably installed in the rectangular box 14. Two sets of limit blocks 21 are fixedly installed on one side of the moving plate 16 close to the pressing plate 5. Connecting plates 15 are fixedly installed on one side of the pressing plate 5 close to the mounting base 2. One end of the connecting plate 15 passes through the mounting base 2 and is fixedly connected to the rectangular box 14 and the moving plate 16. Hold the pressing plate 5 to press the moving plate 16 with the connecting plate 15, so that the moving plate 16 moves to the side away from the pressing plate 5, preparing for the subsequent installation of the protection plate 4.

[0033] Finally, an extension rod 13 is fixedly installed at the top of the protection plate 4. A fixing rod 19 is fixedly installed at the top of the extension rod 13. One end of the fixing rod 19 is slidably installed in the rectangular box 14. Two convex blocks 20 are fixedly installed at the top of both sides of the fixing rod 19. The convex blocks 20 are respectively located at the top of the two sets of limit blocks 21. A telescopic rod 18 is fixedly connected between the side of the moving plate 16 away from the pressing plate 5 and the rectangular box 14. A second spring 17 is fixedly connected between the side of the moving plate 16 away from the pressing plate 5 and the rectangular box 14. The second spring 17 is sleeved outside the telescopic rod 18. Insert the extension rod 13 into the installation groove 201 so that the fixing rod 19 enters the rectangular box 14, making the convex block 20 move above the limit block 21. Release the pressing plate 5. Under the combined action of the second spring 17 and the telescopic rod 18, the moving plate 16 moves towards the side close to the fixing rod 19, making the limit block 21 fixedly installed on the moving plate 16 catch at the bottom of the convex block 20, realizing relative fixation with the fixing rod 19, so that the protection plate 4 is fixedly installed at the bottom of the mounting base 2, realizing the ability to quickly disassemble a single protection plate 4, facilitating the maintenance and replacement of the protection plate 4, and improving the practicability of the device.

[0034] In this embodiment, an arc-shaped frame 6 is slidably installed at the bottom of the protection plate 4. Multiple rubber pads 10 are fixedly installed at the bottom of the arc-shaped frame 6. A transparent flame retardant plate 11 is fixedly installed in the arc-shaped frame 6. The transparent flame retardant plate 11 is made of polycarbonate material. An installation cavity 401 is provided in the protection plate 4. A fixing plate 8 is fixedly installed in the installation cavity 401. Two round rods 7 are slidably installed on the fixing plate 8. The arc-shaped frame 6 is fixedly installed between the ends of the two round rods 7 extending out of the protection plate 4. The welding seat 1 moves downward, so that the welding head 3 welds the welded product. Before the welding head 3 contacts the welded product, the arc-shaped frame 6 first contacts the welded product, reducing the collision between the protection plate 4 and the welded product and increasing the service life of the protection plate 4.

[0035] Among them, baffles 12 are fixedly installed at one end of the round rod 7 located inside the installation cavity 401 and on a part of the rod body located below the fixing plate 8. The baffle 12 prevents the round rod 7 from detaching from the installation cavity 401. A first spring 9 is fixedly connected between the fixing plate 8 and the bottom of the installation cavity 401. The first spring 9 is sleeved outside the round rod 7 respectively. When the arc-shaped frame 6 is squeezed, the round rod 7 moves upward, driving the first spring 9 to be compressed. When the top of the arc-shaped frame 6 moves to contact the bottom of the protection plate 4, the welding head 3 welds the surface of the welded product. The arc-shaped frame 6, the transparent flame-retardant plate 11, and the protection plate 4 cooperate with each other, so that while achieving the purpose of preventing spark splashing, it also avoids the complete occlusion of the welding head 3 by the protection plate 4, facilitating the staff to observe the welding situation, so that problems can be discovered in time and the quality of the welded product can be improved.

[0036] Working principle: During the installation of the present utility model, first hold down the pressing plate 5, insert the extension rod 13 fixedly installed on the top of the protection plate 4 into the installation groove 201, so that the fixing rod 19 fixedly installed on the top of the extension rod 13 enters the rectangular box 14, and the convex block 20 fixedly installed on the top of the fixing rod 19 moves above the limit block 21. Release the pressing plate 5. Under the combined action of the second spring 17 and the telescopic rod 18, the moving plate 16 moves towards the side close to the fixing rod 19, so that the limit block 21 fixedly installed on the moving plate 16 is stuck at the bottom of the convex block 20, realizing relative fixation with the fixing rod 19, thereby fixedly installing the protection plate 4 at the bottom of the mounting seat 2. When it is necessary to disassemble the protection plate 4, just press the pressing plate 5 of the corresponding protection plate 4, and the protection plate 4 can be removed, realizing the ability to quickly disassemble a single protection plate 4, facilitating the maintenance and replacement of the protection plate 4, and improving the practicability of the device;

[0037] During the welding process, the welding seat 1 moves downward, so that the welding head 3 welds the welded product. Before the welding head 3 contacts the welded product, the arc-shaped frame 6 first contacts the welded product, reducing the collision between the protection plate 4 and the welded product, increasing the service life of the protection plate 4, making the arc-shaped frame 6 be squeezed, making the round rod 7 move upward, driving the first spring 9 to be compressed. When the top of the arc-shaped frame 6 moves to contact the bottom of the protection plate 4, the welding head 3 welds the surface of the welded product. The arc-shaped frame 6, the transparent flame-retardant plate 11, and the protection plate 4 cooperate with each other, so that while achieving the purpose of preventing spark splashing, it also avoids the complete occlusion of the welding head 3 by the protection plate 4, facilitating the staff to observe the welding situation, so that problems can be discovered in time and the quality of the welded product can be improved.

[0038] The above specific embodiments are only several alternative embodiments of the present utility model. Based on the technical solution of the present utility model and the relevant revelations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
