DETAILED DESCRIPTION

[0018] 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.

[0019] In order to solve the problems of inaccurate welding temperature control, which may easily lead to glass deformation or cracks; coloring substances may be introduced during the welding process, affecting the transparency and aesthetics of the product; manual operation is inefficient and difficult to ensure consistency; and the technical requirements for operators are high, which increases the training cost. Please refer to Figure 1-Figure 8 , this embodiment provides the following technical solutions: A stain-resistant double-layer glass handle welding machine comprises a base 1, a handle rotating frame 2 and a cup body rotating frame 3. The handle rotating frame 2 and the cup body rotating frame 3 are both mounted on the base 1, and the handle rotating frame 2 and the cup body rotating frame 3 are controlled to rotate synchronously by a transmission component 4. The cup body rotating frame 3 drives the glass cups 5 to move one by one by using an intermittent rotation method. Correspondingly, the handle rotating frame 2 controls the glass handles 6 to move one by one to a position aligned with the glass cups 5. At the same time, the connection between the glass handles 6 and the glass cups 5 is heated to achieve welding.

[0020] Specifically, a first fixed platform 11 is provided at a position of the base 1 close to the handle rotating frame 2, and a second fixed platform 12 is provided at a position of the base 1 close to the cup body rotating frame 3. One end of the first fixed platform 11 is fixedly connected to one end of the second fixed platform 12. The first fixed platform 11 and the second fixed platform 12 are respectively used to support the rotation of the handle rotating frame 2 and the cup body rotating frame 3, and fix the positions of the handle rotating frame 2 and the cup body rotating frame 3. A preheating box 13 is provided on one side of the first fixed platform 11. The preheating box 13 is used to preheat the connecting end of the glass handle 6. The preheating box 13 is provided with a preheating groove 131 according to the welding position of the glass handle 6. An infrared heating lamp tube or an infrared heating plate is provided in the preheating groove 131. When the glass handle 6 is displaced, the welding end moves in the preheating groove 131 to preheat it. The glass handle 6 is thicker than the glass cup 5. Preheating in advance can make the heating more uniform. Accordingly, a cooling box 14 is arranged on one side of the second fixed platform 12. The cooling box 14 and the preheating box 13 are staggered, and a laser welding joint 15 is arranged at one end of the preheating box 13 close to the cooling box 14. The heating position of the laser welding joint 15 corresponds to the connection between the glass cup 5 and the glass handle 6. The laser welding joint 15 heats the glass cup 5 and the glass handle 6 at the same time. During the laser heating process, the contact part between the handle and the cup body softens and fuses to form a firm connection. The first fixed platform 11, the second fixed platform 12, the handle rotating frame 2 and the cup body rotating frame 3 are all made of high-temperature resistant ceramic materials, which have excellent heat insulation and anti-pollution properties, and can effectively prevent the adhesion of dyeing substances during the welding process. The cooling box 14 is used to cool the glass cup 5 after welding. The cooling box 14 adopts water cooling or air cooling. The structure of the air cooling is the same as the cooling component in a handle welding device for glass cup manufacturing disclosed in Chinese patent publication number CN111825317A. The cooling box 14 is an inverted L-shaped structure. The side of the glass cup 5 close to the glass handle 6 after welding is rotated into the cooling box 14 to cool it.

[0021] In addition, a conical truncated cone 111 is fixedly connected to the upper surface of the first fixed platform 11. When the glass handle 6 is installed, the lower end of the glass handle 6 contacts the conical truncated cone 111 to limit the installation height of the glass handle 6. When the glass handle 6 is aligned with the glass cup 5, the glass handle 6 extends from the conical truncated cone 111. The conical truncated cone 111 does not limit the glass handle 6 after welding, so as to prevent the glass handle 6 from being installed loosely before cooling in the early stage of welding. The glass handle 6 after welding does not contact the conical truncated cone 111, which can improve its stability during movement. A limiting circular plate 112 is provided on the upper surface of the conical truncated cone 111, and a protrusion 113 is fixedly connected to the limiting circular plate 112 on the side close to the second fixed platform 12.

[0022] The handle rotating frame 2 includes a hexagonal rotating frame 21 and a movable clamp 22. The lower end of the hexagonal rotating frame 21 is fixedly connected with a first rotating shaft 211. The first rotating shaft 211 penetrates the limiting circular plate 112, the conical truncated cone 111 and the first fixed platform 11, and is movably connected with the first fixed platform 11 through a bearing. Support rods 212 and guide rods 213 are evenly distributed on the side wall of the hexagonal rotating frame 21. The movable clamp 22 includes a movable frame 221, a clamp body 222 and a moving wheel 223. The movable frame 221 is provided with holes matching the support rod 212 and the guide rod 213. The movable frame 221 is sleeved with the support rod 212 and the guide rod 213. The support rod 212 A supporting spring 214 is sleeved on the upper part. Under the action of the supporting spring 214, the movable frame 221 is pushed to fit the side wall of the hexagonal rotating frame 21. The lower end of the movable frame 221 is movably connected with a moving wheel 223. The moving wheel 223 contacts the limiting circular plate 112, and the moving wheel 223 moves along the edge of the limiting circular plate 112. Therefore, when the hexagonal rotating frame 21 drives the movable clamp 22 to move to the position corresponding to the protrusion 113, the protrusion 113 pushes the moving wheel 223 outward, driving the movable frame 221 to move away from the hexagonal rotating frame 21, the supporting spring 214 contracts, and the clamp body 222 drives the clamped glass handle 6 to move to a position aligned with the glass cup 5.

[0023] like Figure 8 As shown, six workstations are arranged on the hexagonal rotating frame 21, which are respectively denoted as workstations AF, wherein workstations A and B are used for installing the glass handle 6, workstation C plays a conveying role, and workstations D and E are used for preheating the glass handle 6. When the glass handle 6 moves to workstation F, the glass handle 6 is pushed out by the action of the protrusion 113, so that the glass handle 6 contacts the side wall of the glass cup 5.

[0024] More specifically, the clamp body 222 includes a micro motor 2221, a main shaft 2222 and a clamping block 2223. The main shaft 2222 is movably connected to the movable frame 221. One end of the main shaft 2222 is connected to the micro motor 2221. The clamping blocks 2223 are symmetrically arranged at both ends of the main shaft 2222. When working, the micro motor 2221 drives the main shaft 2222 to rotate, thereby controlling the rotation of the clamping block 2223. The opposite side of the clamping block 2223 is an inclined structure. When the rotating clamping block 2223 rotates the side close to the glass handle 6 to contact the glass handle 6, the glass handle 6 is clamped. The glass handle 6 is held fixed, on the contrary, when the clamping block 2223 rotates the farthest side to be close to the glass handle 6, the clamping block 2223 cannot form a clamping force on the glass handle 6, thereby controlling the glass handle 6 to relax. A groove is provided on the main shaft 2222 for positioning the glass handle 6. The clamping block 2223 is made of elastic rubber material to provide a stable clamping force. The micro motor 2221 is controlled by the PLC system. After the glass handle 6 is installed, the clamping state is maintained during this period before the welding is completed. When the welding is completed, the micro motor 2221 is controlled to release the clamping of the glass handle 6.

[0025] The cup body rotating frame 3 includes a tray 31, an intermittent rotating disk 32, a driving motor 33 and a dial 34. The lower end of the tray 31 is fixedly connected to a second rotating shaft 311, the second rotating shaft 311 passes through the second fixed platform 12, and the second rotating shaft 311 is provided with an intermittent rotating disk 32 on the lower surface of the second fixed platform 12. The output end of the driving motor 33 is fixedly connected to the dial 34, and the dial 34 rotates under the control of the driving motor 33. When the lever 341 on the dial 34 rotates into the slot 321 of the intermittent rotating disk 32, the intermittent rotating disk 32 is driven to rotate. Because the intermittent rotating disk 32 is provided with a limiting slot 322 matching the dial 34, the rotation angle of the intermittent rotating disk 32 is fixed. Cup holders 312 are equidistantly arranged on the upper surface of the tray 31, and a handle slot 3121 is provided on one side of the cup holder 312. The handle slot 3121 is provided with an expansion slot near the connection position of the glass handle 6 to facilitate the welding of the glass handle 6.

[0026] like Figure 8 As shown, six cup holders 312 are arranged on the tray 31, which are respectively marked as stations a to f, wherein station a is used to install the glass 5, station b is a welding station, the glass 5 after welding is rotated to station ce, and the glass 5 after welding is cooled by the cooling box 14, and station f is used to remove the cooled glass 5, thereby completing the continuous welding process of the glass 5 and the glass handle 6.

[0027] The transmission assembly 4 includes a first gear 41 connected to the second rotating shaft 311, a second gear 42 connected to the first rotating shaft 211, and a transmission gear 43 arranged between the first gear 41 and the second gear 42. Two transmission gears 43 are provided, and the first gear 41 and the second gear 42 are connected by two transmission gears 43, so that the first gear 41 and the second gear 42 rotate towards each other by the same angle, and the installed glass cup 5 and the glass handle 6 are aligned one by one, and the first gear 41, the second gear 42 and the transmission gear 43 are transmitted to realize the linkage between the handle rotating frame 2 and the cup body rotating frame 3.

[0028] Working process: at station a of the cup body rotating frame 3, the glass cup 5 is placed in the cup holder 312. The handle groove 3121 on the cup holder 312 provides a precise alignment position for the subsequent welding of the glass handle 6. At stations A and B of the handle rotating frame 2, the glass handle 6 is clamped and fixed by the fixture body 222. The micro motor 2221 in the fixture body 222 drives the main shaft 2222 to rotate, so that the clamping block 2223 clamps the glass handle 6. The driving motor 33 drives the dial 34 to rotate, and controls the intermittent rotation of the intermittent rotating disk 32 to rotate intermittently, driving the hexagonal rotating frame 21 to rotate intermittently. With the rotation of the hexagonal rotating frame 21, the glass handle 6 passes through stations C, D and E in turn. At stations D and E, the connecting end of the glass handle 6 enters the preheating groove 131 of the preheating box 13, and is evenly preheated by the infrared heating lamp. When the glass cup 5 on the cup body rotating frame 3 rotates to station b, the glass handle 6 moves to the convex When the protrusion 113 is in the corresponding position, the protrusion 113 pushes out the moving wheel 223 of the movable clamp 22, pushing the movable frame 221 to move outward, so that the glass handle 6 extends out from the conical cone 111 and is precisely aligned with the side wall of the glass cup 5. At station b, the laser welding head 15 is aligned with the connection between the glass handle 6 and the glass cup 5, and heats both at the same time. The laser beam softens and fuses the connection area to form a strong connection. After the welding is completed, the cup body rotating frame 3 continues to rotate, and the welded glass cup 5 is brought into station c, station d and station e in turn. During this process, the side of the glass cup 5 close to the glass handle 6 enters the cooling box 14, and is quickly cooled by water cooling or air cooling to eliminate thermal stress and consolidate the connection strength. The glass cup 5 after welding is completed and cooled is rotated to station f, and the operator takes it out of the cup holder 312 to complete the entire welding process. The material is continuously loaded at stations A, B and a, so that uninterrupted glass can be welded.
