Description

Technical Field

[0001] This utility model relates to a rotating adsorption platform. Background Technology

[0002] In the processing of large-area printed circuit board products, the rotary adsorption platform, as the placement carrier, plays a crucial role in the processing quality. Currently, common rotary adsorption platforms mainly use a rotary joint connected to an air pipe for vacuum adsorption to fix the printed circuit board products.

[0003] This traditional adsorption method has some significant drawbacks in practical applications. First, the small orifice diameter of the pipe limits the gas flow rate. When adsorbing large-area printed circuit boards, the limited flow rate makes it difficult to establish a sufficiently strong adsorption force in a short time, thus affecting processing efficiency.

[0004] Secondly, insufficient product flatness leads to poor sealing. Large-area printed boards may experience localized unevenness during production and transportation. In such cases, traditional rotary adsorption platforms struggle to maintain a tight fit to the product surface, resulting in air leakage. This leakage not only reduces adsorption capacity but can also cause the printed board to shift during processing, affecting processing accuracy and quality.

[0005] Furthermore, as the size of printed circuit board products continues to increase, the requirements for adsorption platforms are also becoming more stringent. Low-flow-rate pipelines and poor sealing cannot meet the demands of large-scale, high-precision processing. To address these issues, existing rotary adsorption platforms need to be improved and innovated to enhance their adsorption capacity, stability, and adaptability, thus meeting the processing requirements of printed circuit board products of different specifications. Utility Model Content

[0006] The purpose of this invention is to provide a rotary adsorption platform that solves the problems of poor adsorption capacity and insufficient flatness of large-area printed circuit board products placed on it in existing rotary adsorption platforms.

[0007] The objective of this utility model is achieved through the following technical solution:

[0008] A rotary adsorption platform includes a linear module with a module connecting plate. The module connecting plate has a first channel forming an adsorption port on its upper surface. The module connecting plate can move back and forth on a predetermined track of the linear module. A rotary motor is mounted on the module connecting plate, and the rotary motor has an adsorption main structure with an adsorption platform. The adsorption main structure has a sealing tube communicating with the adsorption holes on the adsorption platform. The lower end of the sealing tube communicates with the adsorption port on the module connecting plate, and the sealing tube is the largest negative pressure channel on the adsorption main structure.

[0009] As a further improvement of one embodiment of the present invention, the adsorption main structure is composed of an adsorption platform, an adsorption platform fixing plate, a motor connecting plate and a sealing tube from top to bottom.

[0010] As a further improvement of one embodiment of this utility model, the bottom of the adsorption platform is provided with a plurality of spaced adsorption notches, each of which is connected to a plurality of adsorption holes; the upper surface of the adsorption platform fixing plate is provided with a platform inlet notch connected to the adsorption notch; the adsorption platform fixing plate is provided with a first negative pressure channel connected to the platform inlet notch; the motor connecting plate is provided with a second negative pressure channel connected to the first negative pressure channel; and the sealing tube has a third negative pressure channel; the diameter of the third negative pressure channel is larger than the diameter of the second negative pressure channel, and the diameter of the second negative pressure channel is larger than the diameter of the first negative pressure channel.

[0011] As a further improvement of one embodiment of the present invention, the platform inlet is provided with a support column for supporting the adsorption platform.

[0012] As a further improvement of one embodiment of the present invention, the adsorption platform, the adsorption platform fixing plate, the motor connecting plate and the sealing tube are centrally located, and the first negative pressure channel, the second negative pressure channel and the third negative pressure channel are vertical channels and are coaxially arranged.

[0013] As a further improvement of one embodiment of the present invention, a sealing ring is provided between the lower end of the sealing tube and the module connecting plate.

[0014] As a further improvement of one embodiment of the present invention, the bottom of the adsorption platform fixing plate is provided with a weight reduction groove, which avoids the platform inlet and the first negative pressure channel.

[0015] The above technical solution has the following beneficial effects: by modifying the adsorption channel on the rotating adsorption platform and expanding the pore size of the sealing tube, the cross-sectional area of ​​the adsorption pipe is increased, thereby increasing the flow rate, improving the adsorption performance, and increasing the adaptability to uneven products.

Example

[0034] See Figures 1-3 As shown, a rotary adsorption platform includes a linear module 9, which provides a stable linear motion track for the entire device. A module connecting plate 7 is provided on the linear module 9, and the module connecting plate 7 can move back and forth on the predetermined track of the linear module 9 to meet processing requirements at different positions. The module connecting plate 7 has a first channel, which forms an adsorption port on the upper end face of the module connecting plate 7.

[0035] A rotary motor 6 is installed on the module connecting plate 7 to provide rotational power for the adsorption main structure, accommodating processing operations at different angles. The rotary motor 6 houses the adsorption main structure, which has a sealing tube 5 communicating with the adsorption holes on the adsorption platform. The lower end of the sealing tube 5 communicates with the adsorption port on the module connecting plate 7, ensuring the transmission of negative pressure. The sealing tube 5 is the largest negative pressure channel on the adsorption main structure, enabling rapid and effective transmission of negative pressure and enhancing adsorption force. Product 1 can be placed on the adsorption platform 2 for adsorption and fixation.

[0036] The main adsorption structure consists of, from top to bottom, an adsorption platform 2, an adsorption platform fixing plate 3, a motor connecting plate 4, and a sealing tube 5. The adsorption platform 2 directly contacts the product 1, and its surface adsorption holes generate uniform adsorption force, fixing the large-area printed circuit board product. The adsorption platform fixing plate 3 provides stable support for the adsorption platform 2, ensuring it does not deform or shift during operation. The motor connecting plate 4 connects the rotary motor 6 and the main adsorption structure, enabling the main adsorption structure to rotate precisely under the drive of the rotary motor 6. The sealing tube 5, as the largest negative pressure channel on the main adsorption structure, is responsible for transferring negative pressure from the module connecting plate 7 to the adsorption platform 2, ensuring efficient transmission of adsorption force. All parts of the main adsorption structure work together to provide reliable adsorption and fixing functions for the processing of large-area printed circuit board products.

[0037] Specifically, the bottom of the adsorption platform 2 is provided with several spaced adsorption notches 21. Each adsorption notch 21 is connected to several adsorption holes 22. When performing adsorption and fixing processing of large-area printed board products, the adsorption force can be generated quickly and evenly through the cooperation of these adsorption holes 22 and adsorption notches 21, ensuring that all parts of the product can be firmly fixed on the adsorption platform.

[0038] The upper surface of the adsorption platform fixing plate 3 is provided with a platform inlet notch 31 that communicates with the adsorption notch 21. The adsorption platform fixing plate 3 is also provided with a first negative pressure channel 32 that communicates with the platform inlet notch 31. This platform inlet notch 31 acts as a transfer station, transmitting the adsorption force in the first negative pressure channel 32 to the adsorption notch 21 and the adsorption hole 22.

[0039] The motor connecting plate 4 is provided with a second negative pressure channel 41 that communicates with the first negative pressure channel 32. The motor connecting plate 4 not only serves to connect the rotary motor 6 and the adsorption main structure, but its second negative pressure channel 41 is also used for the entire negative pressure transmission.

[0040] The sealing tube 5 has a third negative pressure channel 51. It is worth noting that the diameter of the third negative pressure channel 51 is larger than the diameter of the second negative pressure channel 41, and the diameter of the second negative pressure channel 41 is larger than the diameter of the first negative pressure channel 32.

[0041] In use, the first channel on the module connecting plate 7 connects to an external vacuum pump. When the vacuum pump is activated, the vacuum force sequentially passes through the first channel, the third negative pressure channel 51, the second negative pressure channel 41, the first negative pressure channel 32, the platform inlet notch 31, and the adsorption notch 21, acting on the adsorption holes 22 of the adsorption platform. This provides a stable and reliable adsorption and fixation function for the processing of large-area printed circuit board products. The progressively decreasing hole diameter helps to increase the adsorption force within the adsorption holes 22, increasing adaptability to uneven product surfaces. Through this progressively interconnected negative pressure channel design with rationally varying diameters, all parts of the adsorption main structure achieve efficient transmission and utilization of adsorption force.

[0042] To improve the stability of negative pressure transmission, a sealing ring 8 is provided between the lower end of the sealing tube 5 and the module connecting plate 7. The sealing ring 8 effectively fills the tiny gap between the sealing tube 5 and the module connecting plate 7, preventing leakage of negative pressure during transmission. When the device is running, strong negative pressure is transmitted through the sealing tube 5 to the adsorption port on the module connecting plate 7. Without the sealing effect of the sealing ring 8, the negative pressure might leak out from the connection point, thereby reducing the adsorption force and affecting the adsorption and fixation effect on the product. The sealing ring 8 is typically made of a material with good elasticity and sealing properties, capable of adapting to different working conditions and ensuring stable sealing performance under various circumstances.

[0043] Furthermore, support columns 33 are provided on the platform inlet 31 of the adsorption platform fixing plate 3 to support the adsorption platform 2. These columns provide stable support for the adsorption platform 2, ensuring that the adsorption platform remains stable during operation. When adsorbing and fixing large-area printed board products, the support columns 33 can bear the weight of the adsorption platform 2 and the product, preventing the adsorption platform from deforming or tilting due to uneven stress. At the same time, the presence of the support columns also helps to improve the stability and reliability of the entire adsorption structure.

[0044] Preferably, the bottom of the adsorption platform fixing plate 3 is provided with weight-reducing grooves 34. These weight-reducing grooves 34 are deliberately designed to avoid the platform inlet notch 31 and the first negative pressure channel 32, ensuring unobstructed transmission of adsorption force and preventing any adverse effects on the adsorption function. The application of weight-reducing grooves 34 effectively reduces the overall weight of the adsorption platform fixing plate, making the entire rotary adsorption platform more lightweight and flexible during operation, reducing the burden on the drive components, and improving the operating efficiency and stability of the equipment.

[0045] In this embodiment, the adsorption platform 2, the adsorption platform fixing plate 3, the motor connecting plate 4, and the sealing tube 5 are centrally located. This layout makes the entire adsorption structure more compact and stable, which is beneficial to improving the transfer efficiency of adsorption force. At the same time, the central location also makes the equipment more balanced during operation, reducing vibration and noise caused by the shift of the center of gravity.

[0046] The first negative pressure channel 32, the second negative pressure channel 41, and the third negative pressure channel 51 are vertical channels and coaxially arranged. This design has several advantages. First, the vertical channels ensure smoother negative pressure transmission, reducing energy loss. Second, the coaxial arrangement makes the connection between the channels tighter, further improving the transmission effect of adsorption force. In addition, this design also facilitates the installation and maintenance of the equipment and reduces production costs.

[0047] This invention relates to a rotary adsorption platform primarily used for the adsorption and fixation of large-area printed circuit board products. In practical applications, traditional rotary adsorption platforms often suffer from insufficient adsorption force and poor sealing, affecting the processing accuracy and quality of the products. To address these issues, this invention modifies the adsorption channel on the rotary adsorption platform. By enlarging the orifice diameter of the sealing tube (several times larger than before), the cross-sectional area of ​​the adsorption channel is significantly increased. This results in a substantial increase in gas flow rate and enhanced adsorption performance. When the product is placed on the adsorption platform, the strong adsorption force ensures stable fixation during processing, preventing displacement or shaking. This not only improves processing accuracy but also guarantees product quality consistency, increases adaptability to uneven product surfaces, and provides greater compatibility with varying product flatness.
