Description

Technical Field

[0001] This utility model relates to the field of transfer technology, and in particular to a vacuum-assisted positioning device for manual transfer. Background Technology

[0002] In mass production, ensuring precise placement of multiple sheets on the same surface of a product is crucial for guaranteeing product quality, especially when multiple sheets are simultaneously and accurately attached. Existing technologies commonly employ transfer bonding to achieve precise positioning and adhesion between the sheets and the product. A typical solution is the auxiliary fixture for manual transfer disclosed in utility model patent publication number CN218256783U. This type of auxiliary fixture mainly consists of a vacuum generating platform, an annular flexible film, and a transfer fixture plate. The vacuum generating platform has multiple adsorption holes arranged in an array on its surface, while the lower end of the transfer fixture plate has a corresponding vacuum groove. The core function of the annular flexible film is to block the unused adsorption holes on the platform when the transfer fixture plate docks with the vacuum generating platform, ensuring that only the adsorption holes corresponding to the vacuum grooves on the transfer fixture plate remain open, thereby achieving effective vacuum docking between the transfer fixture plate and the vacuum generating platform. Meanwhile, the transfer fixture plate is also equipped with positioning grooves for positioning the sheet, and the positioning grooves have multiple holes that communicate with the vacuum tank. When the sheet is placed upside down in the positioning groove, the adsorption force generated by the holes can stably adsorb the sheet, preventing the sheet from failing to position due to the surface adhesive layer sticking to the operator's hand. In addition, the product positioning posts on the transfer fixture plate can accurately position the product, so that after the product is positioned, it can accurately align and bond with the sheet in the positioning groove. After bonding is completed, the vacuum mechanism can be turned off, and the product and sheet can be easily removed, ultimately achieving precise bonding between the two. However, in actual production applications, this technical solution has significant limitations: when production demands change and require changing the appropriate transfer fixture plate according to different product specifications or sheet materials, the fixed shape and size of the annular flexible film cannot synchronously adapt to different vacuum tank positions and adsorption hole shielding requirements with the change of transfer fixture plate. This necessitates replacing the corresponding annular flexible film every time the fixture is changed. This not only increases the operational steps and time costs of fixture replacement, reducing production efficiency, but also increases consumable costs due to the frequent replacement of the annular flexible film, making it difficult to meet the efficient and flexible process requirements of mass production. Therefore, it is necessary to propose an improved technical solution to address these problems. Utility Model Content

[0003] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.

Through the flexible cooperation between the gas-blocking cap and the first adsorption hole, only the gas-blocking cap corresponding to the first adsorption hole needs to be removed according to the position of the air intake groove of different transfer fixture plates. This eliminates the need to replace the entire blocking component, simplifying the fixture replacement operation, saving replacement time, and improving production efficiency. At the same time, the gas-blocking cap can be reused, avoiding the waste of consumable costs caused by frequent replacement of the annular flexible film. In addition, the transfer fixture plate docks with the adsorption platform through a flexible closed-loop gasket, which not only ensures the airtightness of the docking point but also eliminates the need to customize suitable annular flexible films for different fixtures.

Detailed Implementation

[0017] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] Please see Figure 1-6 In this embodiment of the invention, a vacuum-assisted positioning device for manual transfer includes an adsorption platform 10, a vacuum pump 20, a transfer fixture plate 30, and multiple gas-blocking caps 40. An air extraction chamber 11 is provided inside the adsorption platform 10, and the vacuum pump 20 is connected to the air extraction chamber 11. Multiple first adsorption holes 12 are arranged in an array on the adsorption platform 10, and the gas-blocking caps 40 are connected to the first adsorption holes 12 to provide airtight sealing. An air extraction groove 31 is provided at the lower end of the transfer fixture plate 30, and at least one air extraction groove 31 is provided at the upper end of the transfer fixture plate 30. The sheet positioning groove 32 and the transfer fixture plate 30 are also provided with multiple product positioning posts 33. Multiple second adsorption holes 34 connected to the air suction groove 31 are opened in the sheet positioning groove 32. Flexible closed-loop pads 35 are also provided around the sheet positioning groove 32 at the upper and lower ends of the transfer fixture plate 30. The transfer fixture plate 30 is connected to the adsorption platform 10 through the flexible closed-loop pads 35. The first adsorption hole 12 on the adsorption platform 10 corresponding to the air suction groove 31 is removed with the air blocking cap 40, so that the air suction groove 31 is connected to the air extraction chamber 11 through the first adsorption hole 12 of the removed air blocking cap 40.

[0019] When the manual transfer vacuum-assisted positioning device is working, firstly, according to the position of the suction groove 31 at the lower end of the transfer fixture plate 30, the gas-blocking cap 40 of the first suction hole 12 in the corresponding area on the adsorption platform 10 is removed. The remaining unused first suction holes 12 are then airtightly blocked by the gas-blocking cap 40. Then, the transfer fixture plate 30 is connected to the adsorption platform 10 through the flexible closed-loop gaskets 35 set around the sheet positioning groove 32 at its upper and lower ends to ensure the airtightness of the connection. Next, the vacuum pump 20 is started, and the vacuum pump 20 evacuates the air extraction chamber 11 inside the adsorption platform 10. 1. By removing the first suction hole 12 of the air-blocking cap 40 and connecting it with the suction groove 31 of the transfer fixture plate 30, a negative pressure is formed in the suction groove 31. This negative pressure acts on the sheet placed in the sheet positioning groove 32 through the second suction hole 34 in the sheet positioning groove 32, stably adsorbing and positioning the sheet. Then, the product is positioned by the product positioning post 33 on the transfer fixture plate 30, so that the product and the sheet in the sheet positioning groove 32 are precisely aligned. After the bonding is completed, the vacuum pump 20 is turned off, the negative pressure disappears, and the bonded product and sheet can be easily removed, realizing the entire transfer positioning operation.

[0020] Therefore, this device effectively solves the problem of frequent replacement of the annular flexible film required for changing fixtures in the prior art. Through the flexible cooperation between the gas-blocking cap 40 and the first adsorption hole 12, the gas-blocking cap 40 corresponding to the first adsorption hole 12 can be removed according to the position of the air suction groove 31 of different transfer fixture plates 30, without replacing the entire blocking component. This simplifies the operation steps of fixture replacement, saves replacement time, and improves production efficiency. At the same time, the gas-blocking cap 40 can be reused, avoiding the waste of consumable costs caused by frequent replacement of the annular flexible film. In addition, the transfer fixture plate 30 is connected to the adsorption platform 10 through the flexible closed-loop gasket 35, which can ensure the airtightness of the connection point and eliminate the need to customize the annular flexible film for different fixtures. This improves the adaptability of the device to different specifications of products and sheets, reduces the equipment debugging cost and operation complexity in mass production, and better meets the needs of efficient and flexible mass production.

[0021] Please see Figure 3-4 Based on the above technical solution, it is further proposed that the gas-blocking cap 40 is made of metal material. The gas-blocking cap 40 has a sheet-like part 41 and a pin part 42 axially formed at the lower end of the sheet-like part 41. The pin part 42 is used to insert into the first adsorption hole 12. The sheet-like part 41 abuts against the first adsorption hole 12. A silicone sheet 43 is also attached to the lower end of the sheet-like part 41 and surrounds the pin part 42. The sheet-like part 41 provides airtight blocking for the first adsorption hole 12 through the silicone sheet 43. The gas-blocking cap 40 is made of metal. Its structure, consisting of a sheet-like portion 41 and an axially formed pin portion 42, utilizes the rigidity of the metal to ensure the overall structural strength and durability of the gas-blocking cap 40, extending the service life of the component. Furthermore, the precise insertion and engagement of the pin portion 42 with the first adsorption hole 12 enables rapid positioning and installation of the gas-blocking cap 40 on the adsorption platform 10, improving operational convenience. Simultaneously, the silicone sheet 43, which is attached to the lower end of the sheet-like portion 41 and surrounds the pin portion 42, can tightly adhere to the surface of the adsorption platform 10 and the edge of the first adsorption hole 12 through the elastic deformation of the silicone material when the sheet-like portion 41 abuts against the first adsorption hole 12. This enhances the airtightness of the gas-blocking cap 40 against the first adsorption hole 12, effectively preventing insufficient negative pressure due to gas leakage during vacuuming. This ensures the stability of the transfer fixture plate 30 in adsorbing and positioning the sheet, guaranteeing the accuracy of the product-sheet bonding. The combination of the metal material and the silicone sheet 43 also ensures the reliability of the component for repeated use, reducing maintenance costs during long-term use.

[0022] Please see Figure 1-3Based on the above technical solution, the adsorption platform 10 is further proposed to include a profile support 13, a panel 14 mounted on the profile support 13, and a grooved plate 15 welded to the lower end of the panel 14. A first adsorption hole 12 is formed on the panel 14, and an air extraction chamber 11 is formed between the panel 14 and the grooved plate 15. An air pipe connector 16 is also provided at the lower end of the grooved plate 15. A vacuum pump 20 is mounted on the profile support 13 and connected to the air pipe connector 16. Both the panel 14 and the grooved plate 15 are made of stainless steel, and the flexible closed-loop pad 35 is made of magnetic material. The adsorption platform 10 adopts a combined structure of profile support 13, stainless steel panel 14, and slotted plate 15. The profile support 13 provides stable support for the whole structure. Specifically, it includes a frame structure made of aluminum profiles, four aluminum profiles connected at the four corners of the frame structure as table corners, and I-shaped structures made of aluminum profiles connecting the four table corners. The I-shaped structures can also be used to fix the vacuum pump 20. The overall design ensures the structural stability of the device during operation. The stainless steel panel 14 and slotted plate 15 not only have excellent structural strength and wear resistance, which can extend the service life of the device, but can also form a tight seal through welding. The well-sealed vacuum chamber 11, together with the air pipe connector 16 and the vacuum pump 20, further ensures the airtightness during the vacuuming process and avoids the adsorption effect being affected by chamber leakage. At the same time, the flexible closed-loop pad 35 made of magnetic material can quickly adhere to the stainless steel panel 14, which simplifies the docking operation between the transfer fixture plate 30 and the adsorption platform 10, and enhances the sealing of the docking point through magnetic attraction, ensuring stable negative pressure. Compared with the traditional fixing method, the magnetic docking makes it easier to pick up and put down the transfer fixture plate 30 and adjust its position, further improving the convenience of operation and better adapting to the adaptability requirements of small-batch production.

[0023] Please see Figure 6 Based on the above technical solutions, it is further proposed that the flexible closed-loop pad 35 can also be made of silicone material. Through the elastic deformation of the silicone material, it can be tightly attached to the adsorption platform 10, which can not only ensure the airtightness of the docking point to stabilize the negative pressure adsorption effect, but also have good durability and facilitate the transfer of the fixture plate 30 for placement and removal. At the same time, the cost is low and it is suitable for mass production needs.

[0024] Please see Figure 5-6Based on the above technical solution, the sheet positioning groove 32 is further proposed to be a long strip structure, with multiple second adsorption holes 34 evenly arranged laterally in the sheet positioning groove 32. This can form a uniform and stable adsorption force on the long strip sheet, avoiding the sheet from shifting due to uneven adsorption force and ensuring the positioning accuracy of the long strip sheet. Multiple sheet positioning grooves 32 are provided, and the multiple sheet positioning grooves 32 are arranged longitudinally, which can realize the synchronous positioning of multiple sets of sheets by the same transfer fixture plate 30, increase the sheet processing capacity of a single transfer operation, and improve production efficiency. Four product positioning posts 33 are provided, and the four product positioning posts 33 are respectively set at the four corners of the transfer fixture plate 30. They can position the product from all four edges, effectively limiting the displacement of the product during the bonding process, ensuring precise docking between the product and multiple sets of sheets, and further improving the overall transfer bonding accuracy and consistency.

[0025] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
