DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments 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 creative work are within the scope of protection of the present invention.

[0031] An automatic welding device for a new energy vehicle battery case includes a workbench 1, characterized in that the welding device also includes: a welding mechanism, the welding mechanism includes two welding guns 2, the welding guns 2 are used to weld the case 38, and the welding mechanism is connected to the reciprocating motion mechanism; a grinding mechanism, the grinding mechanism includes two grinding heads 24, the grinding heads 24 are used to grind the welded case 38, and the side of the grinding heads 24 close to the case 38 is arc-shaped; a dust removal mechanism, the dust removal mechanism includes a water outlet pipe 26, the water outlet pipe 26 is used to spray water mist under the grinding heads 24 to avoid dust generation, and can also cool the surrounding environment; a collecting mechanism, the collecting mechanism is used to collect welding slag generated during welding.

[0032] Specifically, there are two welding guns 2 and two grinding heads 24, which are arranged in the height direction, so as to weld and grind the upper and lower sides of the box body 38, thereby improving the welding efficiency; Figure 2 , Figure 8 As shown, the side of the grinding head 24 away from the rotating shaft 23 is arc-shaped, that is, the arc-shaped surface contacts the box 38, so that when the box 38 rotates, the grinding head 24 can contact the edge of the box 38 in time, and the grinding head 24 can also make a smooth transition. At the same time, the edge of the box 38 is also rounded, so the grinding head 24 can grind smoothly during the rotation of the box 38. In addition, two winding reels 17 are provided on the workbench 1, and welding wire is wound on the winding reels 17 to provide welding wire to the welding gun 2.

[0033] The welding mechanism also includes a sliding frame 3, which is fixedly connected to the two welding guns 2. The sliding frame 3 is slidably installed on the workbench 1, and a return spring 3 is arranged between the sliding frame 3 and the workbench 1. The sliding frame 3 is connected to the reciprocating motion component. A collecting shell 4 is arranged below the welding gun 2, and the collecting shell 4 is fixedly connected to the workbench 1. The collecting shell 4 is used to collect welding slag generated during welding.

[0034] Specifically, when the reciprocating assembly drives the sliding frame 3 to move, the sliding frame 3 will drive the welding gun 2 to move, and adjust the distance between the welding gun 2 and the box 38. On the one hand, it can adapt to boxes 38 of different sizes, and on the other hand, it can smoothly complete the welding. During the movement of the sliding frame 3, the reset spring 3 will generate elastic force due to deformation, and the function of the reset spring 3 is to assist the reset of the sliding frame 3.

[0035] A slope 6 and a through hole 5 are provided at the bottom of the collecting shell 4 . The through hole 5 is connected to the collecting mechanism. The height of one end of the slope 6 close to the through hole 5 is lower than the height of the other end of the slope 6 away from the through hole 5 .

[0036] Specifically, Figure 7As shown, with the through hole 1 5 as the left side, the height of the left side of the inclined surface 6 is less than the height of the right side, so that when the welding slag falls into the inclined surface 6, the welding slag will automatically fall into the through hole 1 5 due to the effect of the inclined surface 6.

[0037] The grinding mechanism also includes two rotating shafts 23, which are fixedly connected to two grinding heads 24 respectively. The rotating shafts 23 are installed on a sliding frame 41, and the sliding frame 41 is slidably installed on the workbench 1. A reset spring 4 is arranged between the sliding frame 41 and the workbench 1. A recovery basket 25 is arranged below the grinding head 24. The recovery basket 25 is used to collect waste chips generated by grinding. The recovery basket 25 is connected to the dust removal mechanism, and the grinding head 24 is connected through a power source.

[0038] Specifically, Figure 8 As shown, the power source includes a motor 20 fixedly mounted on a sliding frame 41, the output shaft of the motor 20 is connected to one end of a belt assembly 21, the other end of the belt assembly 21 is connected to a rotating shaft rotatably mounted on the sliding frame 41, a belt assembly 22 is connected to the rotating shaft, and both ends of the belt assembly 22 are respectively connected to two rotating shafts 23. The rotating shaft 23 can slide on the sliding frame 41, and the rotating shaft 23 can rotate on the sliding frame 41, which can be realized in the form of a spline cylinder, such as the spline cylinder is rotatably mounted on the sliding frame 41, and the rotating shaft 23 and the spline cylinder form a spline match, which belongs to the prior art and can be realized by those skilled in the art.

[0039] The reason why the grinding mechanism is not driven by a reciprocating mechanism is that during the grinding process, a certain pressure is required between the grinding head 24 and the box 38 to increase the friction, so the movement of the sliding frame 41 can only be driven by the rotation of the box 38, which can provide a certain pressure.

[0040] The reciprocating motion mechanism includes a moving table 14 slidably mounted on the workbench 1, one side of the moving table 14 is fixedly connected to the sliding rod 13, and the other side of the moving table 14 is connected to a plurality of linearly arranged driving teeth 15, the driving teeth 15 are slidably matched with the driving block 16, the driving block 16 is fixedly mounted on the sliding frame 3, and a U-shaped groove is provided on the sliding rod 13, and the U-shaped groove is connected to the rotating component.

[0041] The rotating assembly includes a driving gear 9, which is rotatably mounted on the workbench 1 and fixedly connected to the output shaft of the motor 7. The driving gear 9 is respectively meshed with the driven gear 10 and the driven gear 2 11. The driven gear 2 11 is rotatably mounted on the workbench 1. The protrusions arranged on the driven gear 2 11 are slidably engaged with the U-shaped groove. The loading platform 12 is coaxially connected to the upper part of the driven gear 2 11. The driven gear 10 is rotatably mounted on the workbench 1, and a rotating disk 39 is coaxially fixedly connected to the lower part of the driven gear 10, and a through hole 3 42 is arranged on the rotating disk 39.

[0042] Specifically, Figure 5 As shown, the diameter of the rotating disk 39 is larger than that of the driven gear 10, and the through hole 3 42 is located on the outside of the driven gear 10. At the same time, a feed port is provided on the workbench 1, and the feed port is located directly below the through hole 1 5, that is, the welding slag will enter the feed port through the through hole 1 5, and when the through hole 3 42 rotates to coincide with the feed port, the welding slag will enter the through hole 3 42.

[0043] The collecting mechanism includes a feed pipe 18, one end of which is fixedly connected to a through hole 3 42, the other end of which is slidably matched with one end of a feed pipe 2 19, the other end of which is connected to a slider 28, the slider 28 is slidably mounted on a collecting box 27, and the collecting box 27 is provided with two through holes 29, the slider 28 is provided with a plurality of linearly arranged driving teeth 2 30, the driving teeth 2 30 and the collecting box 27 are connected to the dust removal mechanism.

[0044] Specifically, Figure 1 , Figure 3 As shown, the collection box 27 is fixedly mounted on the water tank 34 .

[0045] The dust removal mechanism also includes a water tank 34, which is connected to one end of the water outlet pipe 26, and the other end of the water outlet pipe 26 is connected to the recovery basket 25. A piston plate is slidably arranged inside the water tank 34, and the piston plate is fixedly connected to a piston rod 32. The piston rod 32 slides with the water tank 34, and a driving block 2 31 is fixedly installed on the piston rod 32. A reset spring 1 33 is arranged between the driving block 2 31 and the water tank 34, and the driving block 2 31 slides with the driving tooth 2 30.

[0046] Specifically, Figure 9 As shown, the cross-section of the driving tooth 2 30 is an isosceles trapezoid. The driving tooth 2 30 moves horizontally relative to the driving block 2 31, and can reciprocate to drive the driving block 2 31 to rise and fall, thereby driving the piston plate to rise or fall through the piston rod 32, so that the water in the water tank 34 is pressed into the water outlet pipe 26, and then sprayed into the recovery basket 25 through the water outlet pipe 26. A plurality of small holes can be set on one end of the water outlet pipe 26 close to the recovery basket 25, so as to spray water mist to better complete the dust removal.

[0047] A cross 40 is fixedly installed on the workbench 1. The cross 40 is slidably matched with the clamping rod 35. A return spring 2 36 is provided between the clamping rod 35 and the cross 40. The clamping rod 35 is fixedly connected to a clamping plate 37 located below the cross 40. The clamping plate 37 is used to clamp the box body 38.

[0048] Working principle: When welding the box 38, pull the clamping rod 35 upwards, so that the clamping rod 35 drives the clamping plate 37 to move upwards, and then place the box 38 on the stage 12, and release the clamping rod 35 at the same time, so that the clamping plate 37 moves downwards and presses the upper end surface of the box 38 under the action of the return spring 2 36, that is, the box 38 is clamped by the clamping plate 37 and the stage 12. The return spring 2 36 can be set with a corresponding elastic modulus according to actual needs and a suitable return spring 2 36 can be selected to improve the stability of clamping.

[0049] Start the motor 17 fixed on the motor base 8, the motor base 8 is fixedly connected to the workbench 1, and the driving gear 9 fixedly connected to the output shaft of the motor 17 will rotate. The rotation of the driving gear 9 causes the driven gear 10 and the driven gear 2 11 to rotate. When the driven gear 2 11 rotates, the driven gear 2 11 drives the stage 12 to rotate together, so that the box 38 on the stage 12 rotates, and the clamping plate 37 also rotates at this time. When the driven gear 2 11 rotates, the boss below the driven gear 2 11 moves through the U-shaped groove drive 13, that is, the sliding rod 13 drives the moving stage 14 to move horizontally on 1, so that the driving tooth 15 with an isosceles trapezoidal cross section on the moving stage 14 slides relative to the driving block 16 in turn. When the hypotenuse of the isosceles trapezoid contacts the driving block 16, the driving block 16 will slide back and forth in the vertical direction, and the driving block 16 is perpendicular to the sliding direction of the moving stage 14.

[0050] During the movement of the driving block 16, the 3 fixedly connected to the driving block 16 will move the 2 reciprocatingly, so that during the rotation of the box 38, the welding gun 2 adjusts the distance between the box 38 in real time and completes the welding. The welding slag generated during the welding process will fall into the collection shell 4 and move to the through hole 15 through the inclined surface 6.

[0051] In addition, during the rotation of the box 38, the box 38 and the contacting grinding head 24 slide relative to each other, so that the welding seam is ground by the grinding head 24. During the grinding process of the grinding head 24, the motor 20 can be started, and the motor 20 drives the belt assembly 1 21 and the belt assembly 22 to move, so that the belt assembly 22 drives the rotating shaft 23 and the grinding head 24 to rotate, and the grinding is completed. The waste chips generated by the grinding will fall into the recovery basket 25.

[0052] During the rotation of the driven gear 10, the driven gear 10 drives the rotating disk 39 to rotate, and the through hole 3 42 on the rotating disk 39 will intermittently overlap with the discharge port on 1. When the through hole 3 42 overlaps with the discharge port, the welding slag in the through hole 1 5 will enter the through hole 3 42 through the discharge port, and the through hole 3 42 is connected with the discharge pipe 1 18, so the welding slag will enter the discharge pipe 2 19 through the discharge pipe 1 18, and finally fall onto the collection box 27 through the slider 28, and fall into the through hole 2 29 under the action of the slider 28 to complete the recovery. Since the discharge pipe 1 18 and the discharge pipe 2 19 are inclined with respect to the ground, the welding slag entering the discharge pipe 1 18 can enter the discharge pipe 2 19 by gravity.

[0053] During the horizontal movement of the slider 28 along the collecting box 27 (since the rotating disk 39 makes a circular motion, the feeding tube 18 connected to the rotating disk 39 will drive the feeding tube 2 19 to move, and during the rotation of the feeding tube 2 19 relative to the slider 28, the slider 28 is driven to move horizontally), the driving tooth 2 30 on the slider 28 will move horizontally relative to the driving block 2 31. When the inclined surfaces on both sides of the driving tooth 2 30 slide relative to the driving block 2 31, the driving block 2 31 will reciprocate and rise and fall. During the descent of the driving block 2 31, the driving block 2 31 drives the piston plate to move downward, thereby pressing the water in the water tank 34 into the water outlet pipe 26 through the piston plate, and spraying water mist through the end of the water outlet pipe 26 close to the recovery basket 25, thereby achieving the purpose of dust removal.

Under the concept of the present invention, the technical features in the above embodiments or different embodiments may also be combined, the steps may be implemented in any order, and there are many other changes in different aspects of the present invention as above, which are not provided in detail for the sake of simplicity. Although the present invention has been described in detail with reference to the above embodiments, a person of ordinary skill in the art should understand that the technical solutions described in the above embodiments may still be modified, or some of the technical features may be replaced by equivalents.
