Description

Technical Field

[0001] The utility model relates to the technical field of adsorption platforms, and particularly relates to a vacuum adsorption workbench surface structure. Background Art

[0002] An adsorption platform is a common device, mainly used to adsorb and fix PCB / FPC boards during the printing process to ensure the printing accuracy and quality. The adsorption platform usually adopts the vacuum adsorption method. By setting micropores on the platform, the negative pressure generated by a vacuum pump or a negative pressure fan is used to adsorb the board on the platform.

[0003] There are mainly two structures for the existing adsorption platforms. One is to process a cavity on a flat plate, and then paste a resin plate on the surface for sealing. At the same time, the resin plate surface has micropores to play the role of adsorption holes. The other is to use aluminum alloy bonded with glue to form a three-dimensional cavity and the main structure, and the whole is made of all-aluminum alloy material.

[0004] There are some problems with the existing adsorption platforms. For the first structure, the resin plate is pasted on, and the sealing performance is not good, resulting in unstable negative pressure. After long-term use, the resin plate discolors and is not beautiful, and the processing difficulty of the cavity bottom plate is large and the cost is high. Although the second structure solves the problems of sealing performance and processing difficulty, it has a large volume, high cost, insufficient product consistency, and cannot withstand high temperatures. Therefore, according to the technical defects, we propose a vacuum adsorption workbench surface structure that can solve the above problems. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a vacuum adsorption workbench surface structure to solve the following technical problems:

[0006] 1. The technical problem that the poor sealing of the pasted resin plate leads to unstable negative pressure;

[0007] 2. The technical problem that the resin plate discolors and is not beautiful after long-term use;

[0008] 3. The technical problem that the processing difficulty of the cavity bottom plate is large and the cost is high;

[0009] 4. The technical problem that the existing adsorption platform has a large volume and high cost;

[0010] 5. The technical problem that the existing adsorption platform has insufficient product consistency;

[0011] 6. The technical problem that the existing adsorption platform cannot withstand high temperatures.

[0012] The purpose of the utility model can be realized by the following technical solutions:

[0013] A vacuum adsorption workbench structure includes an intermediate vacuum adsorption platform. On both sides of the intermediate vacuum adsorption platform, a left vacuum adsorption platform and a right vacuum adsorption platform are fixedly installed respectively. An on-board detection sensor is fixedly installed on the intermediate vacuum adsorption platform. A brush is fixedly installed on the intermediate vacuum adsorption platform. A connecting column is fixedly installed on the intermediate vacuum adsorption platform. A right vacuum adsorption platform cavity is arranged inside the right vacuum adsorption platform. A right vacuum adsorption platform sealing plate is fixedly installed on the bottom surface of the right vacuum adsorption platform. A vacuum adsorption pipeline joint is fixedly installed on one side of the right vacuum adsorption platform sealing plate away from the right vacuum adsorption platform cavity. An adsorption pipeline is threadedly installed on the side of the vacuum adsorption pipeline joint away from the right vacuum adsorption platform sealing plate.

[0014] As a further solution of the present utility model: A sealing ring is installed between the vacuum adsorption pipeline joint and the right vacuum adsorption platform sealing plate.

[0015] As a further solution of the present utility model: The brush is fixedly installed on the right vacuum adsorption platform cavity.

[0016] As a further solution of the present utility model: The internal structures of the left vacuum adsorption platform and the right vacuum adsorption platform are the same.

[0017] As a further solution of the present utility model: The left vacuum adsorption platform, the intermediate vacuum adsorption platform and the right vacuum adsorption platform form a complete vacuum adsorption platform.

[0018] The beneficial effects of the present utility model: The vacuum adsorption platform of the present utility model is divided into a left vacuum adsorption platform, an intermediate vacuum adsorption platform and a right vacuum adsorption platform. The negative pressure in each area can be controlled separately, so that more printing media can be processed at the same time, improving the work efficiency, meeting the requirements of modern high-speed inkjet printers, solving the problem of low work efficiency in the prior art, ensuring that the negative pressure is more stable and reliable, and having a wide adaptability. This structure not only solves the problems of poor sealing and unstable negative pressure in the prior art, but also can adjust the negative pressure of each area according to actual needs, improving the flexibility and stability of use.

[0019] The vacuum adsorption platform of the present utility model is made of aluminum alloy material. Compared with the resin plate in the prior art, the aluminum alloy material is more heat-resistant, not easy to change color, more beautiful, and has a longer service life. It also improves the stability and durability of the equipment, and reduces the manufacturing cost of the equipment, solving the problems of discoloration and short service life of the resin plate in the prior art.

[0020] The vacuum adsorption platform of the present utility model has a simple structure, is convenient to process, and has a low cost. Compared with the three-dimensional cavity and main structure in the prior art, the production cost is greatly reduced, and the market competitiveness of the product is improved.

[0021] By optimizing the design and layout of the equipment, the volume of the equipment is made smaller, the cost is lower, and at the same time, the product consistency of the equipment is improved.

[0022] Using high-temperature resistant materials enables the equipment to work normally in high-temperature environments, solving the problem that the existing adsorption platforms cannot withstand high temperatures. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0029] Please refer to Figure 1 - Figure 3As shown in the figure, the utility model is a vacuum adsorption workbench surface structure, including an intermediate vacuum adsorption platform 2. On both sides of the intermediate vacuum adsorption platform 2, a left vacuum adsorption platform 1 and a right vacuum adsorption platform 3 are respectively and fixedly installed. An on-board detection sensor 4 is fixedly installed on the intermediate vacuum adsorption platform 2, which is used to detect whether there is a plate placed on the platform, so as to automatically control the opening and closing of the negative pressure, improve the automation degree and working efficiency of the equipment. The left vacuum adsorption platform 1, the intermediate vacuum adsorption platform 2 and the right vacuum adsorption platform 3 form a complete vacuum adsorption platform. The vacuum adsorption platform uses an aluminum alloy flat plate as the main structure, which has good high-temperature resistance and can adapt to more working environments. Its front side is processed with micropores, and its back side is processed with cavities. By combining with another aluminum plate, cavities are formed, and the middle is sealed with sealant. The negative pressures of the left vacuum adsorption platform 1, the intermediate vacuum adsorption platform 2 and the right vacuum adsorption platform 3 in the vacuum adsorption platform can be controlled separately, ensuring that the negative pressure is more stable and reliable, with a wide adaptability. In this way, more printing media can be processed at the same time, improving the working efficiency and meeting the requirements of modern high-speed inkjet printers, solving the problem of low working efficiency in the prior art. This structural design can effectively solve the problem that the resin plate adhesion sealability is not good, resulting in unstable negative pressure, and at the same time avoid the problem that the resin plate discolors and is not beautiful after long-term use. Moreover, the negative pressure of each area can be adjusted according to actual needs, improving the flexibility and stability of use. The vacuum adsorption platform is installed on the workbench bottom plate through a connecting column. A brush 3-5 is fixedly installed on the intermediate vacuum adsorption platform 2. A connecting column is fixedly installed on the intermediate vacuum adsorption platform 2. A right vacuum adsorption platform cavity 3-1 is arranged inside the right vacuum adsorption platform 3.

An adsorption pipeline 5 is threadedly installed on the side of the vacuum adsorption pipeline joint 3-3 away from the right vacuum adsorption platform sealing plate 3-2. The length of the adsorption pipeline 5 is determined according to the actual use situation, and the material of the adsorption pipeline 5 is telescopic PVC.

[0030] A sealing ring 3-4 is installed between the vacuum adsorption pipeline joint 3-3 and the right vacuum adsorption platform sealing plate 3-2. By using the vacuum adsorption pipeline joint 3-3 and the sealing ring 3-4, the sealing performance and stability of the adsorption pipeline 5 are ensured, thereby ensuring the stability of the negative pressure and solving the problems of large processing difficulty and high cost of the cavity bottom plate.

[0031] The brush 3-5 is fixedly installed on the right vacuum adsorption platform cavity 3-1, and the brush 3-5 plays a role in dust prevention and light shielding.

[0033] The working principle of the present utility model:

[0034] Step 1: The aluminum alloy flat plate serves as the main structure. Micro-holes are processed on the front surface of the aluminum alloy flat plate, and cavities are processed on the back surface of the aluminum alloy flat plate.

[0035] Step 2: Select another aluminum alloy plate, combine it with the aluminum alloy flat plate in the first step to form a cavity, and apply sealant at the joint to ensure the airtightness of the cavity.

[0036] Step 3: Divide the vacuum adsorption platform into three modules: the left vacuum adsorption platform 1, the middle vacuum adsorption platform 2, and the right vacuum adsorption platform 3. Install a vacuum adsorption pipeline joint 3-3 and a brush 3-5 on the back of each module.

[0038] Step 5: Install an adsorption pipeline 5 on the vacuum adsorption platform.

[0039] Step 6: A plate detection sensor 4 is installed on the middle vacuum adsorption platform 2.

[0040] Step 7: When the plate detection sensor 4 on the vacuum adsorption platform is triggered and senses that there is a plate on the workbench surface, the side clamps inside the workbench are in place, triggering the vacuum adsorption fan, and generating negative pressure on the workbench surface through the adsorption pipeline 5.

[0041] Step 8: When the work is completed, the vacuum adsorption fan stops working, and the adsorption work is completed.
