Description

Technical Field

[0001] This utility model belongs to the field of welding machine technology, and in particular relates to a welding machine with a guiding and buffering function. Background Technology

[0002] Currently, smart mattresses are modern mattress products designed specifically for human sleep habits, integrating various high-quality and healthy sleep materials through scientific combination. However, in the manufacturing of mattress airbags, the molds for making the airbags are usually placed on a welding machine, and then the airbags are produced through welding. However, in existing welding machines, when the lower mold is transported to the area below the upper mold for pressing, the lower mold is not positioned and guided during the transport process. This results in the lower mold not aligning with the upper mold when it moves to the area below the upper mold. Consequently, when the upper mold presses against the lower mold, it is prone to severe damage, affecting the mold's lifespan. Utility Model Content

[0003] To overcome the shortcomings of the prior art, this utility model provides the following technical solution: a welding machine with a guiding and buffering function, including a frame; a processing table is provided on one side of the frame, and an upper mold and a lower mold are respectively provided on the frame and the processing table, and a transmission component for driving the lower mold to move below the upper mold is also provided at the bottom of the processing table; a guiding and buffering component is installed on both the processing table and the frame, and when the transmission component drives the lower mold to move, the guiding and buffering component provides guidance and buffering for the movement of the lower mold.

[0004] Optionally, the guide buffer assembly includes a guide rod installed at the lower end of the lower mold, a first guide wheel installed on the processing table, and a second guide wheel installed on the frame. The guide rod slides in sequence with the rims of the first guide wheel and the second guide wheel.

[0005] Optionally, the second guide wheel structure is the same as the first guide wheel structure.

[0006] Optionally, the guide rod has inclined surfaces at both ends, and the inclination angle of the inclined surfaces matches the rim end face of the first guide wheel or the second guide wheel.

[0007] Optionally, the guide rod can be polygonal in shape.

[0008] Optionally, the guide buffer assembly also includes a first connecting plate mounted on the processing table. There are several first connecting plates, which are detachably connected to the processing table. Each first connecting plate is equipped with a first guide wheel.

[0009] Optionally, the guide buffer assembly also includes a second connecting plate mounted on the frame. There are several second connecting plates, which are detachably connected to the frame. Each second connecting plate is equipped with a second guide wheel.

[0010] Optionally, each first connecting plate or second connecting plate is equipped with two first guide wheels or two second guide wheels.

[0011] Optionally, the guide buffer assembly also includes a second push cylinder mounted on the frame, and a second connecting plate mounted on the output end of the second push cylinder.

[0012] Optionally, the transmission assembly includes a drive unit installed in the processing table, a rotating shaft on the output end of the drive unit, a robotic arm rotatably mounted on the rotating shaft, and a connecting shaft rotatably connected to one end of the robotic arm; symmetrical supports are provided on the processing table, a movable table is slidably mounted on the supports, a fixed plate is provided on the movable table, a lower mold is mounted on the fixed plate, the connecting shaft is located on the lower surface of the movable table, and guide rods are symmetrically fixed on the lower surface of the movable table.

[0013] In summary, compared with existing technologies, the beneficial effects of this solution are as follows: (1) This application drives the first guide wheel to rotate by friction between the guide rod and the rim of the first guide wheel, thereby providing a driving force for the guide rod, increasing the speed of the moving table and improving welding efficiency. At the same time, the guide rod is located inside the rim, and the two ends of the rim guide and limit the guide rod, thereby making the guide rod more stable during movement and preventing the guide rod from derailing from the rim. (2) Under the action of the second push cylinder, the present application moves downward, thereby playing a buffering role, reducing the upper mold's pressure on the lower mold, thereby reducing the wear and damage of the lower mold, extending the service life of the upper and lower molds, and also achieving a better stamping effect. (3) The present application has inclined surfaces at both ends of the guide rod, and the inclination angle of the inclined surfaces matches the end face of the rim of the guide wheel. This allows the guide rod to be inserted into the end face of the rim of the guide wheel, ensuring that the guide rod is not easily dislodged from the rim of the guide wheel. At the same time, it also ensures the stability of the moving table, ensuring that the lower mold can be accurately moved below the upper mold, which facilitates the pressing effect between the upper and lower molds, reduces the damage to the lower mold, and thus extends the service life of the mold.

[0016] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0017] refer to Figure 1-6 A welding machine with a guiding and buffering function includes a frame 1, a processing table 2, a mold device, a transmission component 6, and a guiding and buffering component. The processing table 2 is fixedly installed on one side of the frame 1 and can be connected together by bolts. The mold device includes an upper mold 3 and a lower mold 4. A first push cylinder 5 is installed on the frame 1. The first push cylinder 5 can be a pneumatic cylinder or a hydraulic cylinder, which is existing technology. Its working principle is the same as that of the hydraulic cylinder in the prior art, so it will not be described in detail. The upper mold 3 is mounted on the output end of the first push cylinder 5, and the lower mold 4 is mounted on the processing table 2. The bottom of the processing table 2 is also equipped with a transmission component 6 for driving the lower mold 4 to move below the upper mold 3. The guide and buffer components are respectively mounted on the processing table 2 and the frame 1, and are located below the lower mold 4 to provide guidance and buffering when the lower mold moves. The airbag is placed on the lower mold 4, and then the transmission component 6 is driven to move the lower mold 4 below the upper mold 3. Then the first push cylinder 5 is driven to move the upper mold 3 down. Then the airbag is prepared by welding and pressing. The transmission component 6 is driven again to make the lower mold 4 return to the processing table 2, and the worker takes out the prepared airbag.

[0018] refer to Figure 4 A first support plate 7 is provided on the output end of the first push cylinder 5, and a second support plate 8 is installed on the lower end of the first support plate 7. The upper mold 3 is installed on the lower surface of the second support plate 8. A plurality of support rods 9 are provided on the frame 1, and a guide ring 10 corresponding to the plurality of support rods 9 is provided on the first support plate 7. The guide ring 10 is sleeved on the support rods 9. Under the action of the support rods 9, the stability and accuracy of the downward movement of the upper mold 3 are improved.

[0019] refer to Figure 2-3The transmission assembly 6 includes a drive component 11, a rotating shaft 12, a robotic arm 13, and a connecting shaft 14. The drive component 11 is installed inside the processing table 2. The drive component 11 can use existing technologies such as motors and reducers, so it will not be described in detail. The rotating shaft 12 is located on the output end of the drive component 11. The robotic arm 13 is rotatably connected to the rotating shaft 12. One end of the connecting shaft 14 is fixed to the lower surface of the lower mold 4, and the other end of the robotic arm 13 is rotatably connected to the connecting shaft 14. The drive component 11 drives the rotating shaft 12 to rotate, and the rotating shaft 12 drives the robotic arm 13 to rotate. While rotating, the robotic arm 13 pushes the upper mold 3 to move.

[0020] refer to Figure 2-6 A support frame 15 is symmetrically mounted on the processing table 2. A movable stage 16 is slidably mounted on the support frame 15. A fixed plate 17 is mounted on the movable stage 16. The lower mold 4 is mounted on the fixed plate 17. The connecting shaft 14 is fixedly mounted on the lower surface of the movable stage 16. Specifically, the guide buffer assembly includes a first connecting plate 18, a first guide wheel 19, and a guide rod 20. The first connecting plates 18 are symmetrically arranged on two supports 15. There are several first connecting plates 18, which are evenly distributed on the supports 15. Each first connecting plate 18 is equipped with a first guide wheel 19. The guide rods 20 are symmetrically mounted on the lower surface of the movable stage 16, and the guide rods 20 are opposite to the first connecting plates 18. The guide rods 20 are located inside the rim of the first guide wheel 19 and slide in cooperation with the rim. When the guide rod 20 moves, the guide rod 20 rubs against the rim of the first guide wheel 19, driving the first guide wheel 19 to rotate. This allows the first guide wheel 19 to provide a pushing force to the guide rod 20, increasing the speed of the movable stage 16 and improving welding efficiency. Meanwhile, the guide rod 20 is located inside the wheel rim, and the two ends of the wheel rim will guide and limit the guide rod 20, so that the guide rod 20 is more stable during movement, and also prevents the guide rod 20 from derailing from the wheel rim.

[0021] refer to Figure 2-6The guide buffer assembly also includes a second connecting plate 21, a second guide wheel 22, and a second push cylinder 23. The second connecting plate 21 is symmetrically fixed on the frame 1, and the second connecting plate 21 and the first connecting plate 18 are on the same horizontal plane. The second guide wheel 22 is installed on the second connecting plate 21, and the structure of the second guide wheel 22 is the same as that of the first guide wheel 19. The second push cylinder 23 is fixed on the frame 1 and is bolted to the frame 1 to facilitate disassembly and maintenance of the second push cylinder 23. The number of second push cylinders 23 is the same as the number of second connecting plates 21. The output end of the second push cylinder 23 is connected to the second connecting plate 21. The second push cylinder 23 is a pneumatic cylinder or a hydraulic cylinder, which is existing technology. Its working principle is the same as that of hydraulic cylinders in existing technology, so it will not be described in detail. During the movement of the moving table 16, the guide rod 20 moves from the first guide wheel 19 to the second guide wheel 22, thus smoothly transferring the lower mold 4 from the processing table 2 to below the upper mold 3, facilitating the processing of the lower mold 4 by the upper mold 3 and improving accuracy. Furthermore, when the upper mold 3 presses against the lower mold 4, it exerts a downward force on the second connecting plate 21. The second connecting plate 21, under the action of the second push cylinder 23, moves downward, thus acting as a buffer, reducing the pressure exerted by the upper mold 3 on the lower mold 4, thereby reducing wear and damage to the lower mold 4, extending the service life of both the upper and lower molds, and achieving a better stamping effect.

[0022] The guide rod 20 has a polygonal shape, which allows it to better fit with the rim end face of the guide wheel, making the movement of the moving table 16 more stable.

[0023] The guide rod 20 has inclined surfaces 24 at both ends, and the inclination angle of the inclined surfaces 24 matches the rim end face of the guide wheel. This allows the guide rod 20 to be engaged into the rim end face of the guide wheel, ensuring that the guide rod 20 is not easily dislodged from the rim of the guide wheel. At the same time, it also ensures the stability of the moving table 16, ensuring that the lower mold 4 can be accurately moved below the upper mold 3, facilitating the pressing effect between the upper mold 3 and the lower mold 4, reducing the possibility of damage to the lower mold 4, and thus extending the service life of the mold.

[0024] refer to Figure 6 Each of the first connecting plate 18 or the second connecting plate 21 is equipped with two first guide wheels 19 or two second guide wheels 22. The two first guide wheels 19 or the two second guide wheels 22 cooperate with the guide rod 20 to roll. This makes the movement of the guide rod 20 more stable on the first guide wheels 19 or the second guide wheels 22.

[0025] The first connecting plate 18 or the second connecting plate 21 is detachably connected to the processing table 2 or the frame 1. The connection method can be bolts or clips, and is not limited in this application. By detaching, the spacing between adjacent first connecting plates 18 or second connecting plates 21 can be adjusted, thereby accommodating moving tables 16 of different lengths and improving the applicability of the equipment.

[0026] Finally, it should be noted that the connection and fixing of each part of the welding machine with guiding and buffering function of this utility model can be achieved by conventional mechanical connection structure. The control system and connection method required between multiple electrical components and driving components can also be achieved by conventional means and can be equipped with corresponding sensors and detectors. As long as the beneficial effect or the specific actions in the above work can be achieved, it can be implemented.
