Description

Technical Field

[0001] The utility model relates to the technical field of transfer equipment, in particular to a vacuum continuous transfer device. Background Art

[0002] Transfer printing technology is widely used in modern industrial production and decoration. In the electronics manufacturing industry, it can transfer fine circuit patterns to circuit boards to ensure stable performance of electronic equipment. In furniture decoration, various exquisite wood grains and stone patterns are perfectly presented on the surface of the board with the help of transfer printing technology, enhancing the aesthetics and added value of the product.

[0003] The transfer material and the workpiece are not tightly fitted, which can easily lead to unclear transfer patterns, bubbles or defects, etc. The transfer efficiency is low, making it difficult to achieve continuous large-scale production. In addition, the transfer effect is not ideal for workpieces with special shapes or curved surfaces, and it cannot adapt well to diverse transfer needs.

[0004] In addition, during the transfer process, due to the lack of advanced environmental control mechanisms, it is difficult to achieve precise environmental control requirements. Dust particles suspended in the air may randomly adhere to the transfer material or workpiece surface, forming bumps or flaws. Moisture, a common impurity, can destroy the chemical stability of the transfer material if its content exceeds the standard, leading to color deviation, blurred patterns, and other problems, seriously affecting the transfer quality.

[0005] Therefore, the utility model proposes a vacuum continuous transfer device. Utility Model Content

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] like Figure 1-4 As shown, the utility model provides a technical solution: a vacuum continuous transfer device, comprising:

[0038] A bottom plate 13 is provided with a support and limiting frame 15 on the top of the bottom plate 13, a support plate 151 is provided on the inner side of the support and limiting frame 15, a hydraulic push rod 131 and a connecting rod 132 are provided between the support and limiting frame 15 and the bottom plate 13, a vacuum chamber 1 is slidably connected between the support and limiting frame 15 and the support plate 151, a top plate 11 and a drive motor 12 are provided on the top of the vacuum chamber 1, an output end of the drive motor 12 passes through the top plate 11 and is connected to the rotating shaft 41, under the action of the drive motor 12, power is provided for the rotation of the rotating shaft 41, and the rotating shaft 41 is driven to rotate by the drive motor 12, so that the transfer head 44 is subsequently rotated to the top of the clamping and fixing mechanism 3 to transfer the mold;

[0039] The fixed plate 14 is arranged on one side of the bottom plate 13. A vacuum pump 141 is provided on the fixed plate 14. The input end of the vacuum pump 141 is fixedly connected to a connecting pipe 142, and the connecting pipe 142 is fixedly connected to the vacuum chamber 1;

[0040] A connecting plate 16 is provided on the other side of the bottom plate 13. An electric push rod 2 is provided on the side of the connecting plate 16 located on the vacuum chamber 1. A sealing guard plate 21 is provided on the side of the electric push rod 2 close to the vacuum chamber 1. A sealing ring 22 is provided on the sealing guard plate 21. A sliding limit groove 23 is provided on the side of the sealing ring 22 close to the vacuum chamber 1. A sliding limit rod 24 and a clamping fixing seat 25 are slidably connected to the sliding limit groove 23. A clamping fixing mechanism 3 is provided on the clamping fixing seat 25.

[0041] The transfer assembly 4 is composed of a rotating shaft 41 rotatably connected between the top plate 11 and the hydraulic push rod 131, a mounting frame 42, a transfer fixing frame 43 and a transfer head 44. There are three transfer fixing frames 43 in total, and the bottoms of the three transfer fixing frames 43 are respectively connected to the corresponding transfer heads 44. Through the setting of the vacuum pump 141, the vacuum pump 141 discharges the air in the vacuum chamber 1 through the connecting pipe 142, so that during the transfer process of the mold, the vacuum chamber 1 is in a vacuum environment, avoiding the presence of air in the vacuum chamber 1 and dust adhering to the air, which causes pollution during the model transfer process and leads to unsatisfactory transfer effect.

[0042] A step further, such as Figure 2 - Figure 4As shown: the connecting plate 16 is an L-shaped structure, the electric push rod 2 is connected to the vertical end of the connecting plate 16, the length and width of the sealing guard plate 21 and the sealing ring 22 are greater than the length and width of the opening of the vacuum chamber 1, and the clamping fixed seat 25 is slidably connected to the sliding limit groove 23 through the sliding limit rod 24. The clamping fixed seat 25 is located directly below one of the transfer heads 44. Further, under the action of the electric push rod 2, the sealing guard plate 21 is controlled to fit and separate from the vacuum chamber 1. When placing materials, the electric push rod 2 is controlled to move the clamping fixing mechanism 3 out of the inner position of the vacuum chamber 1. At this time, under the action of the clamping fixing mechanism 3, it is used to control the installation of the material. After the installation is completed, the electric push rod is controlled The rod 2 fits the sealing guard plate 21 with the vacuum chamber 1, and further, under the action of the sealing ring 22, the connection between the sealing guard plate 21 and the vacuum chamber 1 is fit and sealed to prevent air from entering the interior of the vacuum chamber 1 through the opening of the vacuum chamber 1 when the vacuum pump 141 is turned on, thereby improving the practicality of the device. Under the action of the sliding limit groove 23, the sliding limit rod 24 is limited to prevent the sliding limit rod 24 from separating from the sliding limit groove 23 during use. Further, when the vacuum chamber 1 slides downward in the sliding limit groove 23, sliding space is reserved for the sliding limit rod 24 to prevent the vacuum chamber 1 from being stuck under the action of the sliding limit rod 24, resulting in the vacuum chamber 1 being unable to move downward.

[0043] The above solution still has the problem that the hydraulic push rod 131 is driven to rotate when the rotating shaft 41 rotates. Figure 3 As shown: In this solution, the output end of the driving motor 12 passes through the top plate 11 and is connected to the rotating shaft 41. The top of the hydraulic push rod 131 is rotatably connected to the bottom of the rotating shaft 41. Since the hydraulic push rod 131 is rotatably connected to the bottom of the rotating shaft 41, when the rotating shaft 41 rotates, the hydraulic push rod 131 will not rotate accordingly, thereby avoiding the rotating shaft 41 driving the hydraulic push rod 131 to rotate, causing damage to the hydraulic push rod 131.

[0044] The above solution still has the problem of installing the support plate 151. Figure 3 As shown: In this solution, there are three connecting rods 132, and the three connecting rods 132 are distributed in a ring shape, and the angles between two adjacent connecting rods 132 are equal. Under the action of the connecting rods 132, the bottom of the support plate 151 is auxiliary supported, so that a certain distance is reserved between the support plate 151 and the bottom plate 13, reserving space for the hydraulic push rod 131 to extend and retract.

[0045] Working principle:

[0046] like Figure 1-4As shown, first place the device at the specified position. After the installation is completed, control the electric push rod 2 to drive the clamping and fixing mechanism 3 to move out of the vacuum chamber 1. At this time, place the mold on the clamping and fixing mechanism 3 for clamping and fixing. After the fixing is completed, control the electric push rod 2 to fit the sealing guard plate 21 with the surface wall of the vacuum chamber 1. At this time, turn on the vacuum pump 141 and extract the air in the vacuum chamber 1 through the connecting pipe 142 to form a vacuum environment inside the vacuum chamber 1. At this time, turn on the drive motor 12 to drive the rotating shaft 41 to rotate, so that the three transfer heads 44 rotate in turn to the top of the material. When the transfer head 44 is directly above the material, turn on the hydraulic push rod 131 to drive the rotating shaft 41 to move downward, so that the transfer head 44 fits with the top of the material to complete the transfer.

[0047] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
