Description

Technical Field

[0001] The invention relates to the field of welding, and in particular to welding equipment for producing thermos cups. Background Art

[0002] As people's living standards continue to improve, the demand for thermos cups is growing. As a container that can maintain temperature for a long time, thermos cups are widely used in daily life, outdoor travel and other scenarios. In the production process of thermos cups, welding is one of the key links; but in the existing welding equipment, it is inconvenient to position the thermos cup material during the production process, which makes the angle control inaccurate, easily leading to deviations in the welding position, uneven welding quality, and it is difficult to ensure that each thermos cup material meets the same quality standards when welding. The stability during the welding operation is poor, and the thermos cup is prone to irregular shaking, which not only affects the welding effect, but may also lead to frequent welding errors, thereby reducing production efficiency, poor versatility, and difficult to adapt to different specifications. Thermos cups with different grids and shapes have great limitations; and during the welding process, the welding process may not be smooth enough due to the lack of effective limit flip control. The welding positions required for the thermos cups are different, and the rotating surface of the thermos cups needs to be flipped manually, or the welding head needs to be controlled and adjusted, making it difficult to handle the welding position of the thermos cup material, and the efficiency is relatively low. In the prior art, during the process of feeding argon, the method of feeding argon is not flexible and accurate enough, and it is difficult to make real-time and accurate adjustments according to actual welding needs, resulting in the failure to fully exert the protective effect of argon in some complex welding scenarios, resulting in waste after the argon is fed, affecting the overall use and welding effect.

[0003] For example: the Chinese utility model patent (application number: CN210549090U) discloses a "welding device for thermos cup production", and its specification discloses: the use of stainless steel thermos cups is very widespread nowadays, and the production of stainless steel thermos cups requires welding equipment. The welding equipment currently on the market has the characteristics of stable positioning, etc., but the welding equipment is inconvenient to move, and cannot weld the cup body and the cup head at the same time, resulting in excessive loss of manpower and time; the above patent can prove the defects of the existing technology.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] In the scheme of this application:

[0021] 1. In order to solve the problems of poor stability during welding and poor efficiency of human-controlled rotation and flipping in the prior art, the present application starts the transmission rope winding rod to rotate by setting a first driving motor, so that the rope winding rod reels the nylon sandpaper rope to apply tension to the first limit plate, and then drives the output end of the cylinder to push the fixed frame downward. At this time, the first limit plate applies force on the surface of the thermos cup body to position it. During the process of applying pressure on the first limit plate, the first transmission rod can be driven to rotate by the output end of the second driving motor, so that the first transmission rod can drive the fitted thermos cup body to rotate, so that the thermos cup body can rotate under the welding head, so that the welding head can conveniently weld a circle of the thermos cup body. In order to avoid manual rotation and affect the welding efficiency, after the welding is completed, the first driving motor cancels the rotation of the output shaft so that the first limit plate is pushed away from each other by the magnetic force of the first magnetic block, and then the first limit plate can drive the nylon sandpaper rope to be in a stretched state. At this time, the nylon sandpaper rope can be affected by the stretching and fit with the surface of the thermos cup body. At the same time, the driving cylinder can apply a certain pressure to ensure the fitting effect of the nylon sandpaper rope. At this time, the transmission roller cooperates with the transmission of the transmission equipment to drive the thermos cup body to rotate, so that the welding point part of the thermos cup body can be polished by the nylon sandpaper rope, thereby realizing the effect of rotating the thermos cup body after limiting, and improving the smoothness of the thermos cup body welding process;

[0022] 2. In order to solve the problem of inconvenience in sealing after argon is fed and waste of argon in the prior art, the present application drives the support rod to rotate through the output end of the stepper motor, and the support rod drives the second transmission rod to flip through the cooperation of the pulley and the transmission belt. At this time, the second transmission rod is driven to flip and is parallel to the transmission equipment. Then, the through slot in the open state can transfer the thermos cup body into the welding equipment body, and then the sealing plate is driven by the output shaft of the second transmission rod to flip the sealing plate again, so that the sealing plate can flip and be parallel to the through slot. At this time, the sealing gasket can fit the surface of the welding equipment body to improve the sealing effect of the through slot. After the through slot is closed, one end of the three-way valve can be opened and unfolded. At this time, the vacuum pump in the conveying assembly can drive argon into the welding equipment body, so that the welding equipment body in the sealed state can better and more evenly feed out argon, thereby achieving the effect of protecting argon, thereby avoiding unsatisfactory volatilization effect after argon is fed, resulting in waste and affecting the overall use and welding effect.

[0023] 3. The winding rods and gears are arranged to cooperate with each other, so that when the output shaft of the first driving motor drives one of the winding rods to rotate, the winding rod directly driven can drive the gear to mesh. At this time, the two winding rods can present a state of opposite rotation directions. When the rotation directions of the winding rods are different, the nylon sandpaper rope can uniformly drive the first limit plates to approach and move away from each other, so that the nylon sandpaper rope is straightened when the two first limit plates move away from each other, thereby polishing the surface of the thermos cup body, solving the problem in the prior art that the thermos cup body needs to be manually transported to the polishing equipment for processing after welding, which affects the overall welding process efficiency;

[0024] 4. The positioning plate is limited by the cooperation of the positioning rod and the second magnetic block. When the first driving motor cancels the transmission force, the first limiting plate can be sleeved on the surface of the positioning rod through the positioning plate. The positioning plate can support the first limiting plate. When the first driving motor cancels the transmission force, the second magnetic block on the surface of the support block can be magnetically attracted to the second magnetic block on the surface of the positioning plate, so that the positioning plate can slide on the surface of the positioning rod, so that after the first limiting plate is welded to the thermos cup body, the first limiting plate can be unfolded while maintaining stability.

[0025] 5. Through the cooperation between the provided protective plate and the first magnetic block, when the first limit plate applies pressure to position the thermos cup body, the protective plate can block the splashing impurities welded on both sides of the nylon sandpaper rope, so as to prevent the impurities from splashing onto the surface of the nylon sandpaper rope and damaging the nylon sandpaper rope. At the same time, while protecting the nylon sandpaper rope, the protective plate can cooperate with the repulsive magnetic force of the first magnetic block's surfaces approaching each other to assist in pushing the first limit plate, so that the first limit plate has sufficient power to move, thereby protecting the nylon sandpaper rope, preventing the nylon sandpaper rope from being directly contacted by impurities or high temperature generated during the welding of the thermos cup body, thereby improving the service life and saving costs.

[0040] As described in the background technology, the existing welding equipment makes it inconvenient to position the insulation cup material during the production process, resulting in inaccurate angle control, which can easily lead to deviations in the welding position and uneven welding quality. It is difficult to ensure that each insulation cup material meets the same quality standards when welding, which is not conducive to the welding quality of the insulation cup.

[0041] In order to solve this technical problem, the present invention provides a welding device for producing thermos cups, which is applied to ensure limiting when welding the thermos cups, so that the welding quality is guaranteed.

[0042] Specifically, please refer to Figure 1 - Figure 8 A welding device for producing thermos cups, comprising a welding device body 1, a through slot 2, a transmission device 3, and a welding operation device 4.

[0043] The welding assembly includes a baffle plate 5, which is arranged on the upper surface of the transmission device 3, a transmission roller 6 is rotatably connected to the lower surface of the baffle plate 5, a first support plate 7 is fixedly connected to one side surface of the baffle plate 5, and the upper side of the first support plate 7 away from the baffle plate 5 is a chamfered surface, a first mounting plate 8 is fixedly connected to the surface of the baffle plate 5, a driving cylinder 9 is fixedly connected to the upper surface of the first mounting plate 8, a fixing frame 10 is fixedly connected to the output end of the driving cylinder 9, first limiting plates 15 are arranged on both sides of the fixing frame 10, second limiting plates 17 are arranged on both sides of the first limiting plate 15, and the lower surfaces of the first limiting plate 15 and the second limiting plate 17 are rotatably connected to the first transmission rod 19;

[0044] The welding assembly also includes a first drive motor 11, which is fixedly connected to the outer surface of the fixed frame 10. The surface of the fixed frame 10 is rotatably connected to two rope winding rods 12. The surface of the rope winding rod 12, the output end of the first drive motor 11 is fixedly connected to one of the rope winding rods 12, and the ends of the two rope winding rods 12 away from the first drive motor 11 are fixedly connected to gears 13. A nylon sandpaper rope 14 is wound around the surface of the rope winding rod 12, and the end of the nylon sandpaper rope 14 away from the fixed frame 10 is fixedly connected to the first limiting plate 15.

[0045] The present invention provides a welding device for producing thermos cups. The first driving motor 11 is set to start the transmission rope winding rod 12 to rotate, so that the rope winding rod 12 reels in the nylon sandpaper rope 14 to apply tension to the first limit plate 15, and then drives the output end of the cylinder 9 to push the fixing frame 10 to move downward. At this time, the first limit plate 15 applies force on the surface of the thermos cup to position it.

At this time, the transmission roller 6 cooperates with the transmission of the transmission equipment 3 to drive the thermos cup to rotate, so that the welding point of the thermos cup can be polished by the nylon sandpaper rope 14, thereby realizing the effect of rotating the thermos cup after limiting it, and improving the smoothness of the thermos cup welding process.

[0046] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

[0047] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0048] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0049] Example 1, please refer to Figure 1 - Figure 7, a welding device for producing thermos cups, wherein the welding assembly includes a baffle 5, the baffle 5 is arranged on the upper surface of the transmission device 3, a transmission roller 6 is rotatably connected to the lower surface of the baffle 5, a first support plate 7 is fixedly connected to one side surface of the baffle 5, the upper side of the first support plate 7 away from the baffle 5 is a chamfered surface, a first mounting plate 8 is fixedly connected to the surface of the baffle 5, a driving cylinder 9 is fixedly connected to the upper surface of the first mounting plate 8, a fixing frame 10 is fixedly connected to the output end of the driving cylinder 9, first limiting plates 15 are arranged on both sides of the fixing frame 10, second limiting plates 17 are arranged on both sides of the first limiting plate 15, and first transmission rods 19 are rotatably connected to the lower surfaces of the first limiting plate 15 and the second limiting plate 17;

[0050] The welding assembly also includes a first drive motor 11, the first drive motor 11 is fixedly connected to the outer surface of the fixing frame 10, the surface of the fixing frame 10 is rotatably connected to two rope winding rods 12, the surface of the rope winding rod 12, the output end of the first drive motor 11 is fixedly connected to one of the rope winding rods 12, the ends of the two rope winding rods 12 away from the first drive motor 11 are fixedly connected to a gear 13, the surface of the rope winding rod 12 is wound with a nylon sandpaper rope 14, the end of the nylon sandpaper rope 14 away from the fixing frame 10 is fixedly connected to a first limiting plate 15, the two first limiting plates 15 are fixedly connected to a protective plate 16 on the side close to each other, and the surface of the protective plate 16 is fixedly connected to a first magnetic block 161; during the welding process of the thermos cup, the thermos cup can be placed on the The surface of the operating transmission device 3, and then the thermos cup is moved to the operating welding device body 1 through the transmission of the transmission device 3. At the same time, after the thermos cup is moved into the welding device body 1, the thermos cup can be moved to the side of the baffle 5 through the transmission of the transmission device 3. When the thermos cup reaches the side of the baffle 5 and continues to be subjected to the transmission force, the thermos cup can be pushed to the surface of the first support plate 7 through the transmission force of the transmission device 3, and because the side surface of the first support plate 7 close to the thermos cup is a beveled surface, the arc surface of the thermos cup can be better slid to the surface of the first support plate 7 through the beveled surface when rolling. After the thermos cup is placed on the surface of the first support plate 7, the output end of the driving cylinder 9 can be started to move downward. During the process of starting the driving cylinder 9 The first drive motor 11 can be started at the same time. At this time, the first drive motor 11 drives the rope winding rod 12 to cooperate with the gear 13 to rotate. Then, the two rope winding rods 12 rotate in opposite directions, so that the first limit plates 15 that are far away from each other in the initial state are pulled closer to each other by the nylon sandpaper rope 14. Then, the output end of the driving cylinder 9 applies pressure to push the fixed frame 10 to move downward. In the process of the fixed frame 10 moving downward, the position of the first limit plate 15 and the second limit plate 17 can be driven to move. As the first limit plate 15 and the second limit plate 17 move downward, the first transmission rod 19 can fit with the surface of the thermos cup. Then, the first limit plate 15, the second limit plate 17, and the first transmission rod 19 can perform positioning and limiting work on the thermos cup, and then the welding of the welding operation equipment 4 is completed. The part can be moved down to operate the welding part of the surface of the thermos cup. After the welding process starts, the output shaft of the second drive motor 20 is started to drive the first transmission rod 19 to rotate. At this time, the first transmission rod 19 located below the first limit plate 15 rotates, which can make the thermos cup rotate by the transmission force. At the same time, because the thermos cup is placed on the surface of the first support plate 7, the thermos cup and the surface of the transmission roller 6 are in contact with each other, and the transmission roller 6 is in contact with the transmission surface of the transmission device 3, so that when the transmission roller 6 is rotated by the transmission force of the transmission device 3, the contacted thermos cup is rotated by the rotation force, so that the thermos cup is placed on the surface of the first support plate 7 and rotates, so that the transmission roller 6 and the first transmission rod 19 uniformly drive the thermos cup to rotate.When the thermos cup is limited, it can be rotated by the transmission force, and the stability of the thermos cup during rotation is improved to avoid shaking that affects the welding point. As the thermos cup rotates during welding, the welding part of the welding operation equipment 4 of the welding equipment body 1 can cooperate with the rotating thermos cup to continuously perform welding operations. Since the welding part of the welding operation equipment 4 is located on the side of the thermos cup, the thermos cup can be rotated away from the baffle 5 during the rotation process, and the debris or sputtered impurities generated by the welding can be guided. By rotating the thermos cup to continuously perform welding operations, the thermos cup can be avoided from being welded. The need for manual flipping or the need to pause the welding equipment body 1 leads to poor overall welding continuity of the welding equipment body 1, affecting the overall welding efficiency and quality. After the welding work is completed, the fixed frame 10 can be driven to move by moving the output end of the driving cylinder 9 upward. At this time, during the upward movement of the fixed frame 10, the first limit plate 15, the second limit plate 17, and the first transmission rod 19 are canceled. The force clamping of the thermos cup, and then the first drive motor 11 cancels the transmission force of the output shaft. At this time, the first drive motor 11 cancels the transmission force so that the rope winding rod 12 is canceled. The reeling force of the nylon sandpaper rope 14 is applied, and the surface of the nylon sandpaper rope 14 is wound with wool velvet for polishing. Then, the repelling magnetic force of the two first magnetic blocks 161 pushes the first limit plate 15 away from each other. During the movement of the first limit plate 15 under the influence of the first magnetic block 161, the nylon sandpaper rope 14 is pulled from the surface of the rope winding rod 12 and gradually unfolded. When the nylon sandpaper rope 14 is gradually unfolded and straightened by the pulling force of the first limit plate 15, the fixed frame 10 can be pushed down again by the driving force of the output end of the driving cylinder 9, so that the nylon sandpaper rope 14 can be reeled in and out of the rope winding rod 12. The surface of the paper rope 14 can be closely fitted with the surface of the thermos cup. At this time, by winding the matching wool fleece, the nylon sandpaper rope 14 can be better polished when it is fitted with the thermos cup after welding. At this time, the transmission roller 6 cooperates with the transmission device 3 to drive the rotating thermos cup, which can rotate by itself and polish the surface of the nylon sandpaper rope 14. At this time, the welding point on the surface of the thermos cup can be directly polished by the nylon sandpaper rope 14, so that after welding, the polishing process can be carried out, reducing the tediousness of manual handling to the special polishing equipment, and improving the overall efficiency.

[0051] Example 2, please refer to Figure 4 - Figure 6 , the welding equipment for producing a thermos cup provided in Example 1 is further optimized, specifically, as Figure 5 As shown, the positioning assembly includes a second limit plate 17, both sides of the second limit plate 17 are fixedly connected with a rotating rod, the second limit plate 17 is rotatably connected to the first limit plate 15 through the rotating rod, and torsion springs 18 are arranged on both sides of the second limit plate 17, the torsion springs 18 are sleeved on the surface of the rotating rod, and the two ends of the torsion spring 18 are respectively fixedly connected to the first limit plate 15 and the second limit plate 17;

[0052] The positioning assembly also includes a buffer spring 21, which is evenly fixedly connected to the upper surface of the first limit plate 15. The top of the buffer spring 21 away from the first limit plate 15 is fixedly connected to a second mounting plate 22, and both sides of the surface of the second mounting plate 22 are fixedly connected to positioning plates 23. Both sides of the surface of the fixing frame 10 are fixedly connected to two second support plates 24, and the side of the second support plate 24 away from the fixing frame 10 is fixedly connected to a support block 25. The number of the support blocks 25 is four, and the support blocks 25 are distributed in pairs. A positioning rod 26 is fixedly connected between the facing surfaces of the two support blocks 25, and both ends of the positioning rod 26 A second magnetic block 27 is fixedly connected to the surface of the positioning plate 23, a stepper motor 28 is fixedly connected to the inner wall of the welding equipment body 1, and a support rod 29 is fixedly connected to the output end of the stepper motor 28, and the support rod 29 is fixedly connected to the baffle 5; when the first limit plate 15 is driven to move downward by the fixing frame 10, it contacts the surface of the thermos cup through the first transmission rod 19. At the same time, due to the different diameters of the thermos cup during the welding process, when the second limit plate 17 is driven to move downward by the first limit plate 15, the second limit plate 17 at this time cooperates with the torsion spring 18 through the rotating rod, so that the second limit plate 17 is in the process of moving downward and contacting the thermos cup. In the embodiment, the torsion force of the torsion spring 18 can be used to apply pressure after the thermos cup with a smaller diameter is fitted, and when the thermos cup with a larger diameter is pressed and positioned, the thermos cup can be pressed against the surface of the second limit plate 17, and then the second limit plate 17 cooperates with the rotating rod and the torsion spring 18 to adapt and flip. When the second limit plate 17 remains in contact with the thermos cup, the torsion force of the torsion spring 18 is used again to ensure that the first transmission rod 19 is always in close contact with the thermos cup, so as to ensure that the positioning adaptability of the thermos cup is improved. At the same time, the driving cylinder 9 is elastically buffered by the buffer spring 21 in the process of pushing the fixing frame 10 and the first limit plate 15 downward. The first limit plate 15 and the second limit plate 17 can be prevented from directly colliding with the thermos cup when pushed by the driving cylinder 9, thereby improving the buffering effect. After the welding and polishing of the thermos cup are completed, the stepper motor 28 can be started to drive the support rod 29 to rotate. At this time, the support rod 29 can drive the baffle 5 to flip 180 degrees, so that the baffle 5 drives the processed thermos cup to flip, and then cancel the positioning limit of the thermos cup, so that the thermos cup can fall to the surface of the transmission equipment 3 and be transported out of the welding equipment body 1, which is beneficial to improve the adaptability and positioning stability of the first limit plate 15 and the second limit plate 17 to the thermos cup.

[0053] Example 3, please refer to Figure 6 - Figure 8 , the welding equipment for producing a thermos cup provided in Example 1 or 2 is further optimized, specifically, as Figure 1 and Figure 2 as well as Figure 8The sealing assembly includes a sealing plate 30, which is symmetrically arranged on the surface of the through groove 2. The upper surface of the sealing plate 30 is fixedly connected to the second transmission rod 31, and a sealing pad 32 is fixedly connected to one side of the sealing plate 30. The second transmission rod 31 and the two end surfaces of the support rod 29 are fixedly connected to pulleys 33. The number of pulleys 33 is eight and they are in pairs, and the number of pulleys 33 located on the support rod 29 is four. The surface of the pulley 33 is driven by a transmission belt 34. A conduit 35 is fixedly connected to one side of the upper surface of the welding equipment body 1. The top of the conduit 35 is fixedly connected to a three-way valve 36. The two ends of the three-way valve 36 away from the conduit 35 are respectively fixedly connected to the conveying Component 37, the conveying component 37 is composed of a vacuum pump and a blower; in the process of the stepper motor 28 driving the support rod 29 to flip, the support rod 29 can cooperate with the pulley 33 and the transmission belt 34 to drive the second transmission rod 31 to flip, and the second transmission rod 31 can drive the sealing plate 30 to flip and be parallel to the transmission device 3 when rotating, and then the sealing plate 30 can cancel the closed state of fitting to the surface of the welding equipment body 1, and then open the end of the three-way valve 36 connected to the blower in the conveying component 37, and then start the blower in the conveying component 37 to generate suction force, and then the blower can introduce the opening outside the welding equipment body 1 into the welding equipment body 1, and the outside is passed When the conduit 35 is introduced into the welding equipment body 1, the heat in the welding equipment body 1 can be squeezed out through the opened through slot 2, and then the heat inside the welding equipment body 1 is reduced and the temperature is lowered, so that the thermos cup is cooled and the heating of the welding point is reduced, so as to cooperate with the nylon sandpaper rope 14 to polish the welding point of the thermos cup, and avoid the heating or overheating of the welding point to affect the service life of the nylon sandpaper rope 14. At the same time, when the welding equipment body 1 needs to weld a new thermos cup again, the thermos cup is transmitted by the transmission device 3 into the welding equipment body 1, and the stepper motor 28 drives the support rod 29 to flip and reset to drive the baffle 5 to the initial state. At this time, when the baffle 5 is reset and flipped, it can make The sealing plate 30 is flipped over to be in a state of being in contact with the welding equipment body 1. At this time, the two sealing plates 30 are in conjunction with the sealing gasket 32 ​​to be in contact with the surface of the welding equipment body 1, so that the welding equipment body 1 can be in a closed state with the sealing plate 30 and the sealing gasket 32 ​​at this time, and then the three-way valve 36 can be opened and one end connected to the vacuum pump in the conveying component 37 can be opened. At this time, the vacuum pump will cooperate with the argon storage device to introduce the argon into the welding equipment body 1 through the conduit 35, so that the welding equipment body 1 can be adapted to seal when feeding argon, avoiding the waste of argon, and making better and more uniform use of argon, which is beneficial to ensuring the quality of the thermos cup during welding and reducing the waste of argon during use.

[0054] The use process of the welding equipment for producing thermos cups provided by the present invention is as follows:

[0055] During the welding process of the thermos cup, the thermos cup can be first placed on the surface of the operating transmission device 3, and then the thermos cup can be moved to the operating welding device body 1 through the transmission of the transmission device 3. At the same time, after the thermos cup is moved into the welding device body 1, the thermos cup can be moved to the side of the baffle 5 through the transmission of the transmission device 3. When the thermos cup reaches the side of the baffle 5 and continues to be subjected to the transmission force, the thermos cup can be pushed to the surface of the first support plate 7 through the transmission force of the transmission device 3. Since the side surface of the first support plate 7 close to the thermos cup is a beveled surface, the arc surface of the thermos cup can be better slid to the surface of the first support plate 7 through the beveled surface when rolling. After the thermos cup is placed on the surface of the first support plate 7, the drive can be started at this time. The output end of the cylinder 9 moves downward, and the first drive motor 11 can be started at the same time during the process of driving the cylinder 9 to start. At this time, the first drive motor 11 drives the rope winding rod 12 to cooperate with the gear 13 to rotate, and then the two rope winding rods 12 rotate in opposite directions, so that the first limit plates 15 that are far away from each other in the initial state are pulled closer to each other by the nylon sandpaper rope 14, and then the output end of the driving cylinder 9 applies pressure to push the fixed frame 10 to move downward. In the process of the fixed frame 10 moving downward, the position of the first limit plate 15 and the second limit plate 17 can be driven to move. As the first limit plate 15 and the second limit plate 17 move downward, the first transmission rod 19 can fit with the surface of the thermos cup, and then the first limit plate 15, the second limit plate 17 and the first transmission rod 19 can The cup is positioned and limited, and then the welding part of the welding operation equipment 4 can be moved down to operate the welding part of the surface of the thermos cup. After the welding operation process starts, the output shaft of the second drive motor 20 is started to drive the first transmission rod 19 to rotate. At this time, the first transmission rod 19 located below the first limiting plate 15 rotates, which can make the thermos cup rotate by the transmission force. At the same time, because the thermos cup is placed on the surface of the first support plate 7, the thermos cup and the surface of the transmission roller 6 are in contact with each other, and the transmission roller 6 is in contact with the transmission surface of the transmission device 3, so that when the transmission roller 6 is rotated by the transmission force of the transmission device 3, the contacted thermos cup can be rotated by the rotational force, so that the thermos cup is placed on the surface of the first support plate 7. The transmission roller 6 and the first transmission rod 19 uniformly transmit the rotation of the thermos cup, so that the thermos cup can be rotated by the transmission force when it is limited, and the stability of the thermos cup during rotation is improved to avoid shaking that affects the welding point. As the thermos cup rotates during welding, the welding point of the welding operation equipment 4 of the welding equipment body 1 can cooperate with the rotating thermos cup to continuously perform welding operations, and because the welding point of the welding operation equipment 4 is located on the side of the thermos cup, the thermos cup can be rotated away from the baffle 5 during the rotation process, and the debris or sputtered impurities generated by the welding can be guided. By rotating the thermos cup to continuously perform welding operations, it is avoided that the thermos cup needs to be manually turned over or the welding equipment body 1 needs to be paused during welding, resulting in poor overall welding continuity of the welding equipment body 1.The overall welding efficiency and quality are affected. After the welding work is completed, the fixed frame 10 can be driven to move by moving the output end of the driving cylinder 9 upward. During the upward movement of the fixed frame 10, the first limit plate 15, the second limit plate 17, and the first transmission rod 19 are canceled. The force clamping of the thermos cup, then the first drive motor 11 cancels the transmission force of the output shaft. At this time, the first drive motor 11 cancels the transmission force so that the rope winding rod 12 cancels the winding force on the nylon sandpaper rope 14, and the surface of the nylon sandpaper rope 14 is wrapped with wool velvet for polishing. Then, the repulsive magnetic force of the two first magnetic blocks 161 pushes the first limit plate 15 away from each other. During the movement of the first limit plate 15 by the first magnetic block 161, the nylon sandpaper rope 14 can be pulled from the rope winding rod 12. The surface of the nylon sandpaper rope 14 is gradually unwound and stretched out. When the nylon sandpaper rope 14 is gradually unwound and stretched out by the pulling force of the first limit plate 15, the fixed frame 10 can be pushed down again by the driving force of the output end of the driving cylinder 9, so that the surface of the nylon sandpaper rope 14 can be closely fitted with the surface of the thermos cup. At this time, the nylon sandpaper rope 14 can be better polished when it is fitted with the thermos cup after welding by winding the matching wool fleece. At this time, the driving roller 6 cooperates with the transmission device 3 to drive the rotating thermos cup, which can rotate by itself and polish the surface of the nylon sandpaper rope 14. At this time, the welding point on the surface of the thermos cup can be directly polished by the nylon sandpaper rope 14, so that after welding is completed, the polishing process can be carried out, reducing the tediousness of manual handling to the special polishing equipment, thereby improving the overall efficiency.

[0056] When the first limit plate 15 is driven by the fixing frame 10 to move downward, it contacts the surface of the thermos cup through the first transmission rod 19. At the same time, due to the different diameters of the thermos cups during the welding process, when the second limit plate 17 is driven by the first limit plate 15 to move downward, the second limit plate 17 cooperates with the torsion spring 18 through the rotating rod, so that when the second limit plate 17 moves downward to fit the thermos cup, it can apply pressure through the torsion force of the torsion spring 18 after fitting with the thermos cup with a smaller diameter, and when the thermos cup with a larger diameter is pressed and positioned, the thermos cup can be against the surface of the second limit plate 17, and then the second limit plate 17 cooperates with the rotating rod and the torsion spring 18 to flip over. When the second limit plate 17 remains in contact with the thermos cup, the torsion force of the torsion spring 18 is used again to ensure that the first transmission rod 19 is always in close contact with the thermos cup. To ensure that the positioning adaptability of the thermos cup is improved, at the same time, when the driving cylinder 9 pushes the fixing frame 10 and the first limit plate 15 to move downward, the elastic buffering of the buffer spring 21 can prevent the first limit plate 15 and the second limit plate 17 from directly contacting the thermos cup when being pushed by the driving cylinder 9, thereby improving the buffering effect. After the thermos cup is welded and polished, the stepper motor 28 can be started to drive the support rod 29 to rotate. At this time, the support rod 29 can drive the baffle plate 5 to flip 180 degrees, so that the baffle plate 5 drives the processed thermos cup to flip, and then cancels the positioning limit of the thermos cup, so that the thermos cup can fall to the surface of the transmission equipment 3 and be transported out of the welding equipment body 1, which is conducive to improving the adaptability and positioning stability of the first limit plate 15 and the second limit plate 17 to the thermos cup;

[0057] In the process of the stepper motor 28 driving the support rod 29 to flip, the support rod 29 can cooperate with the pulley 33 and the transmission belt 34 to drive the second transmission rod 31 to flip. At this time, the second transmission rod 31 can drive the sealing plate 30 to flip and be parallel to the transmission device 3 when rotating. Then the sealing plate 30 can cancel the closed state of fitting to the surface of the welding equipment body 1, and then open the end of the three-way valve 36 connected to the blower in the conveying assembly 37, and then start the blower in the conveying assembly 37 to generate suction force, and then the blower can introduce the opening outside the welding equipment body 1 into the welding equipment body 1, and when the outside is introduced into the welding equipment body 1 through the conduit 35, the heat in the welding equipment body 1 can be squeezed out through the opened through groove 2, and then the heat inside the welding equipment body 1 is reduced and the temperature is lowered, so that the thermos cup is cooled and the heating of the welding point is reduced, so as to cooperate with the nylon sandpaper rope 14 to polish the welding point of the thermos cup to avoid heating or overheating of the welding point affecting the nylon sandpaper rope 14. Service life. At the same time, when the welding equipment body 1 needs to weld a new thermos cup again, the thermos cup is transmitted by the transmission equipment 3 into the welding equipment body 1. At this time, the stepper motor 28 drives the support rod 29 to flip and reset to drive the baffle 5 to the initial state. At this time, when the baffle 5 is reset and flipped, the sealing plate 30 can be flipped to a state of being in contact with the welding equipment body 1. At this time, the two sealing plates 30 are both matched with the sealing gasket 32 ​​to fit the surface of the welding equipment body 1, so that the welding equipment body 1 can be matched with the sealing plate 30 and the sealing gasket 32 ​​to be in a closed state. Then the three-way valve 36 can be opened and one end of the vacuum pump connected to the conveying component 37 can be opened. At this time, the vacuum pump will cooperate with the argon storage device to introduce the argon into the welding equipment body 1 through the conduit 35, so that the welding equipment body 1 can be adapted to seal when feeding argon, avoiding the waste of argon, and making better and more uniform use of argon, which is beneficial to ensuring the quality of the thermos cup welding and reducing the waste of argon during use.
