[0001] The utility model relates to welding equipment related technical field especially cup handle welding machine. BACKGROUND

[0002] In the field of metal cup manufacturing, the welding of cup handles is a key process link. Traditional welding methods usually use manual operation or simple mechanical equipment, and these methods have many shortcomings in practical application. First, the traditional welding method is easy to cause scratches on the surface of the metal cup, especially during clamping and alignment, as there is a lack of precise control means, the scratch problem is difficult to avoid. Secondly, uneven heat distribution during welding may cause the appearance of flower shell on the surface of the metal cup, affecting the appearance quality and service life of the product. In addition, the existing equipment has low alignment accuracy of the cup handle and the cup during welding, which easily leads to welding position deviation, thereby affecting the welding strength and aesthetics. These problems not only reduce the production efficiency, but also increase the product failure rate, which is difficult to meet the demand of modern manufacturing industry for high-precision and high-quality production. Therefore, a cup handle welding equipment capable of precise alignment, stable welding and avoiding surface damage is urgently needed to solve the above technical problems and improve the overall production level. SUMMARY

[0003] The utility model aims at providing cup handle welding machine to overcome the deficiencies in prior art.

[0004] In order to achieve the above-mentioned purpose, the utility model provides the following technical scheme:

[0005] A cup handle welding machine, comprising a machine table, a base plate, a water cup jig and a sliding system, a handle jig and a lifting system, a high-frequency heating system and an alignment clamping system. Among them:

[0006] The base plate is fixedly arranged on the machine table and serves as the installation basis of the equipment, and the sliding rail system and the cylinder seat are arranged on the base plate for supporting and guiding the movement of other functional components. Further, the sliding rail system on the base plate is composed of a pair of sliding rails, bearings are arranged on the sliding rails, and the bearings are fixedly connected with the bottom of the water cup jig, so as to realize the sliding movement of the water cup jig in the horizontal direction.

[0007] In particular, the water cup jig is used to load the cup to be welded, and the horizontal movement of the water cup jig is controlled by the horizontal sliding cylinder. The horizontal sliding cylinder is fixed on the base plate through the cylinder seat, the piston rod of the horizontal sliding cylinder is fixedly connected with the water cup jig, and the water cup jig is driven to move horizontally along the sliding rails when the horizontal sliding cylinder is started.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0021] The present invention will now be described in detail with reference to the embodiments shown in the accompanying drawings:

[0022] A cup handle welding machine, combined with Figs. 1 to 3 The structure shown is described in detail below. This device, through optimized structural design and welding methods, achieves precise alignment and smooth welding of the metal cup handle, while avoiding scratches or chipping on the cup surface during welding.

[0023] like Fig. 1As shown, the cup handle welding machine of this utility model includes a machine base, a base plate 1, a cup fixture 2 and a sliding system, a handle fixture 9 and a lifting system, a high-frequency heating system, and a positioning and clamping system. The base plate 1 is fixedly mounted on the machine base, serving as the installation foundation for the entire device. A pair of slide rails 4 are provided on the base plate 1, with bearings 3 sliding on the slide rails 4. The bearings 3 are fixedly connected to the bottom of the cup fixture 2. The cup fixture 2 is used to load the cup to be welded and is moved left and right by a horizontal sliding cylinder 6. The horizontal sliding cylinder 6 is fixed to the base plate 1 by a cylinder seat 5, and its piston rod is fixedly connected to the cup fixture 2. When started, it drives the cup fixture 2 to move left and right along the slide rails 4. The stroke range of the horizontal sliding cylinder 6 is designed according to actual welding requirements to ensure that the cup fixture 2 can accurately reach the welding position.

[0024] The operating table is located on the rear side of the substrate 1, and a lifting handle fixture 9 is mounted on its top. The lifting handle fixture 9 is controlled to move up and down by a lifting cylinder 15, the bottom of which is fixedly connected to the handle fixture 9. The bottom of the handle fixture 9 has an inwardly recessed handle-shaped groove with a negative pressure channel connected to an external negative pressure pump for adsorbing and fixing the cup handle 16. The shape of the handle-shaped groove matches the shape of the cup handle 16 to ensure that the cup handle 16 remains stable and does not shift during adsorption. The movement of the lifting cylinder 15 is controlled by a program to ensure that the timing of the up and down movement of the handle fixture 9 during the welding process is accurate.

[0025] The high-frequency heating system includes a high-frequency heating tube 13 and a positioning heating plate 7. For example... Fig. 2 As shown, the high-frequency heating tube 13 is embedded in the receiving groove of the alignment heating plate 7, which is fixedly mounted on the base plate 1. One side of the alignment heating plate 7 has an alignment port 14 for the cup's tab to pass through. (The tab mentioned throughout refers to the end of the cup that needs to be heated, which, after heating, can be molten and heat-bonded to the handle.) After the tab ends pass through the alignment port 14, they undergo localized high-frequency heating on the high-frequency heating tube 13 to achieve a heat-melt bonding connection. The power and frequency of the high-frequency heating tube 13 are optimized to heat only the tab ends, avoiding energy waste and material property changes caused by overall heating. The heating time, power, and frequency have all been experimentally verified to meet the welding requirements of different materials.

[0026] The alignment and clamping system includes an alignment stage, an alignment cylinder 10, front and rear pressing cylinders 11, and a pressing plate 12. For example... Fig. 3As shown, the alignment platform is located on the rear side of the cup fixture 2. An alignment cylinder 10 and a front-to-back pressing cylinder 11 are mounted on the alignment platform. The alignment cylinder 10 is arranged front-to-back, and its piston rod has a tab alignment block 8 fixed to its front end for adjusting the tab position to ensure precise alignment between the tab and the high-frequency heating tube 13. The shape and size of the tab alignment block 8 are optimized to accommodate tabs of different sizes. The piston rod of the front-to-back pressing cylinder 11 passes through the alignment platform, and a pressing plate 12 is fixed to its front end. After the tab alignment is completed, the pressing plate 12 moves forward to stably clamp the cup in conjunction with the cup fixture 2. The pressing plate 12 is made of a wear-resistant material with appropriate elasticity to reduce pressure concentration on the cup body and prevent scratches or damage to the cup surface due to mechanical contact.

[0027] The working process of this utility model is as follows: S1 Place the cup to be welded on the cup fixture 2; S2 Activate the alignment cylinder 10, whose piston rod pushes the electrode alignment block 8 forward to adjust the electrode position and complete the alignment; S3 Activate the front and rear pressing cylinder 11, whose piston rod pushes the pressing plate 12 forward to press one end of the cup, cooperating with the cup fixture 2 to achieve stable clamping of the cup; S4 Activate the horizontal sliding cylinder 6, driving the cup fixture 2 to move towards the alignment heating plate 7, and after the electrode end passes through the alignment port 14, it is subjected to high-frequency heating on the high-frequency heating tube 13; S5 After heating is completed, the horizontal sliding cylinder 6 drives the cup fixture 2 back to below the handle fixture 9; S6 Activate the lifting cylinder 15, driving the handle fixture 9 to move downward, and heat-melt glue the cup handle 16 to the electrode of the cup. In this embodiment, the material of the cup handle 16 is plastic. Note that after the cup handle and the cup are connected, the handle fixture 9 will release the suction of the cup handle to facilitate the cup handle to detach from the handle fixture 9.

[0028] This invention ensures precise alignment of the electrode tabs and the high-frequency heating tube 13 through the cooperation of the electrode tab alignment block 8 and the alignment cylinder 10, improving welding efficiency and quality. The clamping design of the front and rear pressing cylinders 11 and the pressing plate 12 prevents the cup from shifting during welding, ensuring a stable and reliable welding process. The high-frequency heating tube 13 only locally heats the end of the electrode tab, avoiding energy waste and material property changes caused by overall heating. The negative pressure channel design of the handle fixture 9 is optimized to ensure uniform distribution of adsorption force, preventing the cup handle 16 from deforming or falling off during adsorption. The entire welding process is completed collaboratively by the cylinder and slide rail system, which is simple to operate and suitable for mass production. The sequence and speed of cylinder action are controlled by a program to ensure coordinated operation between components, improving the automation level and work efficiency of the equipment.

[0029] The cup handle welding machine ensures precise alignment between the electrode lugs and the high-frequency heating tube through the cooperation of the electrode lug alignment block and the alignment cylinder, thereby improving welding efficiency and quality. The shape and size of the electrode lug alignment block have been optimized to accommodate electrode lugs of different sizes.

[0030] In particular, the clamping design of the front and rear pressing cylinders and the pressing plate prevents the cup from shifting during welding, ensuring a smooth and reliable welding process. The pressing plate is made of a wear-resistant material with appropriate elasticity to reduce pressure concentration on the cup body and prevent scratches or damage to the cup surface due to mechanical contact.

[0031] Furthermore, the high-frequency heating tube only heats the tip of the electrode locally, avoiding energy waste and material property changes caused by overall heating. The heating time, power, and frequency of the high-frequency heating tube have all been experimentally verified to meet the welding requirements of different materials.

[0032] In particular, the negative pressure adsorption of the cup handle and the stable clamping design prevent scratches or damage to the cup surface caused by mechanical contact. The negative pressure channel design of the handle fixture has been optimized to ensure even distribution of adsorption force and prevent the cup handle from deforming or falling off during the adsorption process.

[0033] This invention significantly improves the efficiency and quality of cup handle welding by optimizing the structural design and workflow, while effectively protecting the cup surface and meeting actual production needs. The modular design of the equipment facilitates maintenance and upgrades, reducing production costs and ease of use. In summary, this invention, through improvements to the equipment structure and welding method, solves the problems of easily scratching the cup surface and low welding efficiency in existing technologies when welding cup handles to metal cups, achieving the goals of precise alignment and stable welding, and possesses high practicality and promotional value.

[0034] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered within the scope of this specification. For those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
