Description

Technical Field

[0001] This utility model relates to the field of aluminum cup spraying technology, and in particular to a tooling for aluminum cup spraying. Background Technology

[0002] Aluminum cups, as a common daily necessity, are widely used in the market due to their lightweight, good thermal conductivity, and high plasticity. To enhance the aesthetics, corrosion resistance, and added value of aluminum cups, the spraying process has become a crucial step in their production. By spraying various colors of paint or functional coatings onto the surface of the aluminum cup, not only can it be given a rich and varied appearance, but its resistance to wear and chemical corrosion can also be improved. And to achieve the ideal spraying effect, the fixture used to hold the aluminum cup plays a vital role.

[0003] In existing placement fixtures, some designs are quite complex, increasing manufacturing costs and making loading, unloading, and maintenance difficult. Furthermore, some existing fixtures use simple clamps to hold the aluminum cups in place, but these clamps are prone to uneven clamping force, causing the aluminum cups to wobble or shift during spraying, resulting in uneven coating. Moreover, when dealing with aluminum cups of different sizes, the position and dimensions of the clamps often need to be changed or adjusted, indicating poor adaptability and potentially impacting production efficiency.

[0010] In a preferred embodiment, the tray has a groove whose shape corresponds to the shape of the bottom of the aluminum cup, so that the bottom of the aluminum cup can be placed in the groove, and the other end of the through hole is located in the groove.

[0011] In a preferred embodiment, the system further includes a spraying mechanism, which is mounted on the conveying mechanism to form a spraying area.

[0016] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0017] This embodiment provides a tooling for spraying aluminum cups, such as... Figures 1 to 10 As shown, the device includes a base 21, a connecting rod 22, and a tray 23. One end of the connecting rod 22 is rotatably mounted on the base 21 around its own axis, and the axis of the connecting rod 22 coincides with the axis of the base 21. The other end of the connecting rod 22 is connected to the tray 23. The aluminum cup 3 is placed on the tray 23, which is provided with an adsorption part for adsorbing the aluminum cup 3 onto the tray 23. The base 21 is mounted on the conveying mechanism 1, which is used for spraying and conveying the aluminum cup 3.

[0018] Specifically, one end of the connecting rod 22 is rotatably mounted on the base 21 around its own axis, causing the aluminum cup 3 on the tray 23 to be in a dynamic rotating state during the spraying process. This allows for more uniform spraying of the aluminum cup 3, improving spraying quality and enhancing the appearance of the sprayed aluminum cup 3. Furthermore, the tray 23 is equipped with an adsorption part that firmly holds the aluminum cup 3 onto the tray 23, ensuring that the aluminum cup 3 does not shift during spraying and guaranteeing smooth spraying. The conveying mechanism 1 continuously and stably conveys the aluminum cup 3, improving production efficiency. This embodiment uses a tooling consisting of the base 21, connecting rod 22, and tray 23, as... Figure 1 As shown, the structure is simple, which helps to reduce manufacturing and subsequent loading, unloading, and maintenance costs.

[0019] like Figures 4 to 6 , Figure 8As shown, this embodiment also includes an adsorption plate 14, a suction nozzle 15, and a vacuum pump (not shown in the figure). The adsorption plate 14 is fixedly mounted on the conveying mechanism 1. The adsorption plate 14 has a plurality of mounting holes 16 along the conveying direction of the conveying mechanism 1. The suction nozzle 15 is fixed in the mounting holes 16. The suction port of the vacuum pump is connected to the suction nozzle 15. The connecting rod 22 has an axial through hole 24, one end of which extends through the base 21, and the other end of the through hole 24 extends through the tray 23 to form the adsorption part; The adsorption plate 14 is located below the base 21. When the conveying mechanism 1 conveys the base 21, connecting rod 22, tray 23 and aluminum cup 3 to the adsorption plate 14, the position of the through hole 24 corresponds to the position of the suction nozzle 15 of the adsorption plate 14. The suction nozzle 15 generates suction in the through hole 24 to adsorb the aluminum cup 3 onto the tray 23.

[0020] The vacuum pump used in this embodiment can continuously and stably provide negative pressure, generating a uniform and stable suction force at the adsorption plate 14 through the connected suction nozzle 15. This embodiment uses multiple suction nozzles 15 to facilitate the simultaneous adsorption and positioning of multiple aluminum cups 3, with each nozzle 15 corresponding to a specific fixture.

[0021] Furthermore, in this embodiment, suction is only generated in the area of ​​the adsorption plate 14 to adsorb the aluminum cup 3 onto the tooling, while other areas of the conveying mechanism 1 do not generate suction, making the structure of the entire device simpler and helping to reduce production and maintenance costs.

[0022] The conveying mechanism 1 in this embodiment can automatically convey the base 21, connecting rod 22, tray 23, and aluminum cup 3 onto the suction plate 14, achieving rapid positioning of the aluminum cup 3 and greatly improving production efficiency. Compared with traditional mechanical clamping and positioning devices, the entire device has a simpler structure, eliminating the need for complex clamps and transmission mechanisms, making subsequent maintenance more convenient and improving reliability and service life. Using suction to position the aluminum cup 3 avoids damage such as clamp marks on the surface of the aluminum cup 3 caused by traditional mechanical clamping and positioning methods, ensuring the integrity and aesthetics of the aluminum cup 3 surface. The suction method for adsorbing the aluminum cup 3 has strong adaptability to the material and shape of the aluminum cup 3, improving the versatility and flexibility of production.

[0023] like Figures 1 to 3 , Figure 7 and Figure 8 As shown, this embodiment also includes a bearing housing 26, a transmission wheel 61, a transmission belt 62, and a first motor 63; The bearing seat 26 is fixedly mounted on the conveying mechanism 1. The base 21, connecting rod 22, and tray 23 are rotatably mounted on the bearing seat 26. The axis of the bearing seat 26 coincides with the axis of the connecting rod 22. One end of the through hole 24 extends through the bearing seat 26. Two drive wheels 61 and a first motor 63 are mounted on the conveying mechanism 1. The output end of the first motor 63 is connected to one of the drive wheels 61. The drive belt 62 is sleeved on the two drive wheels 61, and the transmission direction of the drive belt 62 is consistent with the conveying direction of the conveying mechanism 1. The drive belt 62 is used to abut against the base 21 to drive the aluminum cup 3 to rotate around the axis of the connecting rod 22.

[0024] In this embodiment, the first motor 63, in conjunction with the transmission wheel 61 and the transmission belt 62, drives the entire fixture to rotate around its own axis on the bearing seat 26, resulting in more uniform spraying and improved spraying quality. The base 21 of the fixture can be cylindrical to facilitate power transmission when the transmission belt 62 contacts the base. Patterned grooves 25 can be formed on the outer circumference of the base 21 to increase friction between the base 21 and the transmission belt 62, ensuring smooth spraying operations. The structure is simple. Of course, other driving methods can be used in other embodiments, such as directly installing a rotating motor at the bottom of the base 21 to drive the base 21, connecting rod 22, and tray 23 to rotate on the bearing seat 26. However, this is not a limitation, and users can configure it according to their actual needs.

[0025] like Figure 8 As shown, the conveying mechanism 1 in this embodiment includes a roller 11, a sprocket, a chain 12, a flap 13, and a second motor; Two rollers 11 are arranged parallel to each other, and each roller 11 has a sprocket at both ends (not shown in the figure). Two chains 12 are respectively arranged parallel to the sprockets of the two rollers 11. A flap 13 is mounted between the two chains 12 to form a chain 12 type conveyor belt. A bearing seat 26 is fixedly mounted on the flap 13. One end of the through hole 24 extends through the flap 13. An adsorption plate 14 is arranged between the two chains 12 and located below the flap 13. The output end of the second motor is rotatably connected to the rollers 11 (not shown in the figure) and is used to drive the bearing seat 26, base 21, connecting rod 22 and tray 23 on the flap 13 to rotate.

[0026] In this embodiment, the conveying mechanism 1 adopts a chain 12 type conveyor belt, which helps to improve the rigidity and strength of the entire conveying mechanism 1, enabling it to adapt to long-term, high-intensity production operation and ensuring production continuity. At the same time, the operation mode of the chain 12 type conveyor belt makes the flip plate 13 more stable during movement, which can stably convey the aluminum cup 3 and ensure the coating quality.

[0027] Specifically, due to the light weight of the aluminum cup 3, when the flip plate 13, together with the bearing seat 26, tooling, and aluminum cup 3, moves onto the adsorption plate 14, a strict vacuum seal is not required between the suction nozzle 15 of the adsorption plate 14 and the through hole 24 at the bottom of the flip plate 13. The position of the through hole 24 only needs to correspond to the position of the suction nozzle 15 of the adsorption plate 14, while there can be a certain gap between the through hole 24 at the bottom of the flip plate 13 and the suction nozzle 15. At this time, the suction nozzle 15 can generate suction in the through hole 24 to adsorb the aluminum cup 3 onto the tray 23. While ensuring the adsorption and positioning of the aluminum cup 3, the bottom of the flip plate 13 will not interfere with the adsorption plate 14 or the nozzle 45, ensuring the smooth progress of subsequent spraying. The structure is simple and the design is ingenious.

[0028] like Figure 8 As shown, the conveying mechanism 1 in this embodiment can be mounted on the frame 5, wherein the frame 5 can adopt a cuboid structure for easy manufacturing and installation. The entire conveying mechanism 1 can be set on the upper part of the frame 5, and the lower part of the frame 5 reserves rotation space for tooling, resulting in a simple structure. Of course, the first motor 63 and the transmission wheel 61 in this embodiment can also be mounted on the frame 5.

[0029] like Figure 1 and Figure 2 As shown, the diameter of the tray 23 in this embodiment is smaller than the diameter of the top opening of the aluminum cup 3, so that the aluminum cup 3 can be placed on the tray 23 through the top opening.

[0030] Since the diameter of tray 23 is smaller than the diameter of the top opening of aluminum cup 3, the operator can easily and quickly place aluminum cup 3 onto tray 23 through the top opening. This placement method allows for spraying of the outer surface of aluminum cup 3 in the subsequent spraying process, and the structure is simple.

[0031] like Figure 1 and Figure 3 As shown, the tray 23 of this embodiment has a groove 25. The shape of the groove 25 corresponds to the shape of the bottom of the aluminum cup 3 so that the bottom of the aluminum cup 3 can be placed in the groove 25, and the other end of the through hole 24 is located in the groove 25.

[0032] Since the shape of the groove 25 of the tray 23 corresponds to the shape of the bottom of the aluminum cup 3, the operator can easily and quickly place the bottom of the aluminum cup 3 in the groove 25. This placement method allows for spraying the inner surface of the aluminum cup 3 in the subsequent spraying process, and the structure is simple.

[0033] like Figure 8 and Figure 9 As shown, this embodiment also includes a spraying mechanism 4, which is disposed on the conveying mechanism 1 to form a spraying area 10. The spraying mechanism 4 includes a first turntable 41, a second turntable 42, a first cylinder 43, a second cylinder 44, and a nozzle 45. The first turntable 41 is horizontally set, the first cylinder 43 is set on the first turntable 41 and the output end of the first cylinder 43 is horizontally set, the second cylinder 44 is set on the output end of the first cylinder 43 and the output end of the second cylinder 44 is vertically set, the second turntable 42 is vertically set on the output end of the second cylinder 44, and the nozzle 45 is set on the second turntable 42.

[0034] The first turntable 41, the second turntable 42, the first cylinder 43, and the second cylinder 44 enable the nozzle 45 to have multi-dimensional and multi-angle adjustment capabilities, adapting to aluminum cups 3 of different specifications and improving coating quality and flexibility. The first turntable 41 can be fixedly mounted on the frame 5 using screws or other methods, resulting in a simple structure that is easy to install and remove.

[0035] like Figure 8 and Figure 10 As shown, this embodiment also includes a first cross clamp 46, a second cross clamp 47, a first adjusting rod 48, and a second adjusting rod 49; The first cross clamp 46 is disposed on the second turntable 42. One end of the first adjusting rod 48 passes through the first cross clamp 46, and the other end of the first adjusting rod 48 is provided with a second cross clamp 47. One end of the second adjusting rod 49 passes through the second cross clamp 47, and the nozzle 45 is disposed at the other end of the second adjusting rod 49. The first adjusting rod 48 is horizontally disposed, and the second adjusting rod 49 is vertically disposed.

[0036] This embodiment, by adding a first cross clamp 46, a second cross clamp 47, a first adjusting rod 48, and a second adjusting rod 49, can effectively extend the movement distance of the nozzle 45. For example, when spraying the inner surface of the aluminum cup 3, the nozzle 45 needs to be at a higher position than the outer surface of the aluminum cup 3. The positions of the first adjusting rod 48 and the second adjusting rod 49 are adjusted by the first cross clamp 46 and the second cross clamp 47, so that the nozzle 45 can meet the positional requirements such as spraying height and angle. The structure is simple.

[0037] In this embodiment, each flap 13 can be equipped with multiple tooling fixtures as needed. In this embodiment, two tooling fixtures are provided, such as... Figure 4 , Figure 5 and Figure 8As shown, correspondingly, two sets of spraying mechanisms 4 are provided, one set for spraying the outer surface of the aluminum cup 3 and the other set for spraying the inner surface of the aluminum cup 3. Of course, the two sets of spraying mechanisms 4 can be configured with the same structure or with differences. That is, both sets can be equipped with the first cross chuck 46, the second cross chuck 47, the first adjusting rod 48 and the second adjusting rod 49, or neither set can be equipped with the first cross chuck 46, the second cross chuck 47, the first adjusting rod 48 and the second adjusting rod 49, or only one set can be equipped with the first cross chuck 46, the second cross chuck 47, the first adjusting rod 48 and the second adjusting rod 49. Users can set it according to actual needs. Of course, in order to prevent the spraying mechanisms 4 from interfering with each other during spraying, a mask can also be set in the spraying area 10 to separate the two sets of spraying mechanisms 4 from the two toolings and the aluminum cup 3 on the flip plate 13.

[0038] The working process of this embodiment is as follows: The operator places the aluminum cup 3 onto the tray 23 of the fixture through the top opening or directly places the bottom of the aluminum cup 3 into the groove 25 of the tray 23. The second motor drives the chain 12 to move the flip plate 13 and the fixture to the suction plate 14 of the spraying area 10. At this time, the second motor stops, and the through hole 24 of the fixture corresponds to the suction nozzle 15 of the suction plate 14. The vacuum pump, in conjunction with the suction nozzle 15, generates suction in the through hole 24 to adsorb the aluminum cup 3 onto the tray 23. At the same time, the first motor 63, in conjunction with the transmission wheel 61 and the transmission belt 62, drives the base 21, connecting rod 22, tray 23 and aluminum cup 3 to rotate around the axis of the bearing seat 26. The spraying mechanism 4 performs spraying operations on the outer or inner surface of the aluminum cup 3. After the spraying operation is completed, the second motor starts again, and the chain 12 drives the flip plate 13 and the sprayed aluminum cup 3 to flow out of the spraying area 10.

[0039] The directional terms used in this specification are defined relative to the structures shown in the accompanying drawings. They are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive.

[0040] The above description is only a preferred embodiment of this utility model and is not intended to limit the design of this case. All equivalent changes made based on the key design of this case shall fall within the protection scope of this case.
