Description

Technical Field

[0001] This utility model relates to the field of glass product processing equipment, and in particular to a cup body positioning and fixing device for welding glass cups. Background Technology

[0002] A glass with a handle is a common everyday item, typically consisting of a body and a handle. To ensure the integrity and aesthetics of the glass, the handle needs to be joined to the body using a welding process. During welding, the glass body and handle are heated to a molten state, then precisely aligned and secured to ensure the finished product has good sealing properties and structural strength. However, due to the special nature of glass, the welding process demands high precision in positioning and securing; even slight errors can affect the weld quality.

[0003] Existing glass welding equipment typically includes a worktable for holding the glass and a welding device for heating. Since the top of the glass usually has a spout, and the handle needs to be located behind the spout, the glass's placement angle must be limited during welding to ensure that the relative position of the handle and the spout meets design requirements.

[0004] Existing equipment typically achieves this by manually adjusting the position of the cup, but this method has significant limitations. First, manual alignment requires operators to have a high level of experience and skill, and complete alignment often takes a long time. Second, if the cup tilts or shifts during the welding process, it will lead to inaccurate welding positions, which in turn affects the welding quality and may even result in scrap.

[0023] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0024] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0025] This embodiment mainly describes the structure of the glass welding machine, as follows:

[0026] A glass body positioning and fixing device for welding glass cups, such as Figures 1-6As shown, the assembly includes a welding machine 1, a welding torch 2, a mounting frame 3, a placement frame 4, a motor 5, a fixing rod 6, a first connecting frame 7, a pressure sensor 8, a first elastic element 9, a contact wheel 10, a controller 11, and a reset mechanism. The welding machine 1 is equipped with an electric lead screw, which allows the molten handle to approach the cup body for splicing. A movable welding torch 2 is located at the rear end of the welding machine 1. The mounting frame 3 is connected to the left side of the welding machine 1. The motor 5 is mounted at the bottom of the mounting frame 3. The placement frame 4 is rotatably connected to the mounting frame 3. The output shaft of the motor 5 passes through the top plate of the mounting frame 3 and is fixedly connected to the placement frame 4. A fixing rod 6 is connected to the mounting frame 3. A first connecting frame 7 is slidably connected to the top of the mounting bracket 6. A first elastic element 9 is fitted onto one end of the first connecting frame 7 connected to the fixed rod 6. The upper end of the first elastic element 9 is connected to the first connecting frame 7, and the lower end is connected to the fixed rod 6. A contact wheel 10 is slidably connected to the other end. A pressure sensor 8 is mounted on the top of the contact wheel 10, located inside the first connecting frame 7. When the first connecting frame 7 is at the top, the first elastic element 9 is in a stretched state. A controller 11 is mounted on the mounting bracket 3, connected by wires to the motor 5 and the pressure sensor 8. A reset mechanism for moving the first connecting frame 7 is provided on the mounting bracket 3. When the contact wheel 10 contacts the cup body, if it is not aligned with the cup body notch, the contact wheel 10 will slide upwards within the first connecting frame 7. The pressure sensor 8 will then contact the first connecting frame 7 and send a signal to the controller 11. The controller 11 will start the motor 5, driving the mounting bracket 4 to rotate until the cup body notch aligns with the contact wheel 10. The contact wheel 10 will then fall, the pressure sensor 8 will stop sending signals, and the motor 5 will stop.

[0027] like Figures 3-6 As shown, the reset mechanism includes a base 12, a movable plate 13, a gear 14, a first rack 15, a second rack 16, a follower assembly, a guide rod 21, and a second elastic element 22. The base 12 is connected to the fixed rod 6. The movable plate 13 is slidably connected to the base 12, and a "protrusion" is provided at the bottom of the movable plate 13 to ensure that the movable plate 13 will not detach from the base 12. The gear 14 is rotatably connected to the right side of the movable plate 13. The first rack 15 is connected to the left side of the first connecting frame 7. The guide rod 21 is slidably connected to the movable plate 13. The follower assembly is connected to the rear end of the guide rod 21. The second rack 16 is connected to the front end of the follower assembly. Both the first rack 15 and the second rack 16 mesh with the gear 14. The first rack 15 is located in front of the gear 14, and the second rack 16 is located on top of the gear 14. The second elastic element 22 is sleeved on the guide rod 21. One end of the second elastic element 22 is connected to the movable plate 13, and the other end is connected to the follower assembly.

[0028] like Figure 4 and Figure 5As shown, the follower assembly includes a second connecting frame 17, a movable plate 18, a limiting plate 19, and a lever 20. The second connecting frame 17 is connected to the guide rod 21, and the end of the second elastic element 22 is connected to the second connecting frame 17. The movable plate 18 is rotatably connected to the bottom rear end of the second connecting frame 17, and the limiting plate 19 is connected to the rear side of the bottom rear end of the second connecting frame 17. The limiting plate 19 and the movable plate 18 are in a limiting engagement. The left end of the welding torch 2 is connected to the lever 20, which is in a pressing engagement with the movable plate 18. When the welding torch 2 moves backward, the lever 20 contacts the movable plate 18, which pulls the second connecting frame 17 backward through the movable plate 18, causing the second rack 16 and the gear 14 to move, thereby resetting the first connecting frame 7.

[0029] like Figure 1 As shown, it also includes a baffle 23. The baffle 23 is connected to the lower side of the first connecting frame 7 to isolate the high temperature during the welding process and protect other components.

[0030] like Figure 1 As shown, it also includes a handle 24. The top of the first connecting frame 7 is connected to the handle 24, which makes it easy for the staff to manually adjust the position of the first connecting frame 7.

[0031] like Figure 2 As shown, it also includes a fastening pad 25. The inner side of the placement rack 4 is connected to the fastening pad 25 to fix the cup body and prevent it from sliding during rotation.

[0032] like Figure 2 As shown, it also includes a sponge pad 26. The outer ring of the contact wheel 10 is fitted with a sponge pad 26 to increase the friction between the contact wheel 10 and the cup body, ensuring that the contact wheel 10 can accurately detect the cup body notch.

[0033] like Figure 5 As shown, it also includes a roller 27. The left front end of the lever 20 is rotatably connected to the roller 27. When the lever 20 contacts the movable plate 18, the roller 27 reduces the friction and makes the movement smoother.

[0034] The worker places the glass cup in the middle of the placement rack 4 and fixes the handle to the right end of the welding machine 1. Then, the moving plate 13 is pulled to the left, sliding on the base 12 and moving the follower assembly and gear 14. At this time, the first elastic element 9 rebounds, pulling the first connecting frame 7 downwards along the fixed rod 6, causing the pressure sensor 8 and contact wheel 10 to move downwards until the contact wheel 10 contacts the cup. If the contact wheel 10 is not aligned with the cup notch, it will slide upwards within the first connecting frame 7, causing the pressure sensor 8 to contact the first connecting frame 7 and sending a compression signal to the controller 11. Upon receiving the signal, the controller 11 starts the motor 5, which drives the placement rack 4 to rotate, causing the cup to rotate until the cup notch aligns with the contact wheel 10. At this point, the contact wheel 10 falls, the pressure sensor 8 disengages from the first connecting frame 7, stops sending signals, and the motor 5 shuts off, indicating that the cup is aligned and the outlet is facing away from the handle to be welded.

[0035] Next, the welding torch 2 moves forward to heat the cup body and handle. During the heating process, the operator pushes the moving plate 13 to the right, and the gear 14 on the moving plate 13 meshes with the first rack 15, driving the relevant components to move. After the heating time is reached, the welding torch 2 moves backward to reset, simultaneously driving the lever 20 to move backward. Since the limiting plate 19 restricts the rearward rotation of the movable plate 18, when the lever 20 contacts the movable plate 18, the movable plate 18 pulls the second connecting frame 17 backward, which in turn pulls the second rack 16 backward, causing the gear 14 to rotate counterclockwise. The rotation of the gear 14 pushes the first rack 15 upward, causing the first connecting frame 7 to slide upward, stretching the first elastic element 9, and causing the contact wheel 10 to disengage from the cup body. At the same time, the second elastic element 22 is stretched, and the guide rod 21 slides within the moving plate 13, maintaining the movement state of the reset mechanism and ensuring that the first connecting frame 7 can be reset smoothly.

[0036] Subsequently, welding machine 1, driven by an electric lead screw, brings the melted handle closer to the cup body, completing the splicing. The worker removes the welded glass, places a new cup body inside, and pulls the moving plate 13 again. At this moment, the second elastic element 22 rebounds, causing the second connecting frame 17 to reset. The first elastic element 9 also rebounds, pushing the first connecting frame 7 downwards, causing the contact wheel 10 to re-engage with the cup body, initiating a new round of notch alignment and welding. This process is repeated continuously, achieving efficient welding operations.

[0037] When fixing the cup, the fastening rubber pad 25 inside the placement frame 4 ensures a stable connection of the cup and rotates with the motor 5; the baffle 23 is used to isolate the high temperature during the welding process; the handle 24 can assist the first connecting frame 7 in resetting or temporarily adjusting the position of the glass; the sponge pad 26 increases the contact effect between the contact wheel 10 and the cup, ensuring detection accuracy. In addition, when the second connecting frame 17 is pulled out, the lever 20 moves with the welding gun 2 and will still contact the movable plate 18. At this time, the roller 27 contacts the movable plate 18, reducing friction and making the movement smoother. Although the movable plate 18 can rotate forward, the design of the roller 27 effectively reduces the frictional resistance during contact, ensuring the stability and reliability of the device operation.
