Description

Technical Field

[0001] The utility model relates to the technical field of electrode processing, in particular to a large vacuum suction cup workbench. Background Art

[0002] The PICP lower electrode is an important part of the dry engraving machine in the dry engraving process of the liquid crystal panel. According to the different sizes of the PICP lower electrode, the PICP lower electrode can be divided into G4.5, G5, G5.5, G6, G6.5, G7, G8, G8.5, G10, and G10.5. The electrode size of the small era is about 0.7-0.9m, and the electrode size of the large era can reach 3-3.5m. The PICP lower electrode is a flat-plate component. During conventional processing, in order to ensure the processing accuracy, the component needs to be clamped and fixed. Usually, multiple screw clamps are used to fix the parts on the work surface of the machine tool, or multiple small vacuum suction cups are used to fix them together. This not only has low loading and unloading efficiency, but also if electrodes of different eras need to be processed, the required work surface will be different due to the different positions of the positioning holes, and the on-site operation will be very troublesome.

[0003] Therefore, it is necessary to provide a large vacuum suction cup workbench to solve the above problems. Utility Model Content

[0004] In order to overcome the above-mentioned shortcomings, the purpose of the utility model is to provide a large vacuum suction cup workbench with a simple structure, suitable for processing electrodes of different sizes, high loading and unloading efficiency, and improved electrode processing efficiency.

[0006] Furthermore, the vacuum vent is opened along the length direction of the suction cup base, and one end is connected to the vacuum generating mechanism, and the other end is blocked by a sealing plug. The vacuum vent is arranged along the length direction of the suction cup base to expand the surface adsorption area. When working, one end of the vacuum vent is blocked, and the other end is connected to the vacuum generating mechanism. It should be noted that in some embodiments, the sealing plug is specifically a rubber plug to ensure that no external air enters the vacuum vent through the blocked gap, thereby avoiding vacuum loss, and the vacuum generating mechanism specifically adopts a vacuum pump or a negative pressure generator.

[0007] Furthermore, the plurality of longitudinal through holes are located on the same straight line parallel to the width direction of the suction cup base. By arranging the longitudinal through holes, the air pressure in each vacuum vent hole in the suction cup base is kept consistent.

[0008] Furthermore, at least one of the two sides of the suction cup base in the length direction is horizontally provided with a fixing hole extending to the inside, and the fixing hole is connected to the longitudinal through hole close to it. By providing the fixing hole, it is convenient to block the fixing hole before vacuuming the vacuum vent hole, thereby ensuring that the external air does not enter the vacuum vent hole from the longitudinal through hole, ensuring that the product can be adsorbed on the surface of the suction cup base, and at the same time, it is convenient for the staff to operate to block it.

[0009] Furthermore, the suction cup base is provided with a plurality of threaded connection holes penetrating therethrough in the height direction, and the suction cup base and the machine tool workbench are connected by locking bolts passing through the threaded connection holes. By providing the threaded connection holes, the suction cup base can be fixed on the machine tool workbench, which is convenient for processing the electrode adsorbed on the suction cup base. The suction cup base can be quickly disassembled and installed, and the loading and unloading efficiency of the suction cup base is improved. It should be noted that the threaded connection holes and the vacuum vent holes are arranged in a staggered manner.

[0010] Furthermore, the upper surface of the suction cup base is provided with a plurality of positioning threaded holes, and each of the positioning threaded holes is correspondingly connected to a limiting plate, which can position the electrode to be processed placed on the suction cup base to ensure the subsequent processing accuracy of the electrode.

[0011] Furthermore, a cooling water channel is horizontally laid on the suction cup base between the vacuum vent hole and the bottom thereof.

[0012] Furthermore, the cooling water channel is arranged in an S-shaped continuous bend.

[0019] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0020] See attached Figures 1 to 3 As shown, a large vacuum suction cup workbench in this embodiment is detachably mounted on a machine tool workbench, and includes a plurality of horizontally spliced ​​suction cup bases 1, and a plurality of the suction cup bases 1 are pre-spliced ​​or disassembled to meet the processing requirements of electrodes of different sizes, and the vacuum vents 3 on two adjacent suction cup bases 1 correspond to each other one by one, and a silicone sealing strip is provided in the gap between the connection sides to ensure that there will be no leakage and vacuum loss during the subsequent vacuum adsorption process;

[0021] A plurality of vacuum vent holes 3 are arranged side by side inside the suction cup base 1, and both ends of the vacuum vent holes 3 extend to the side of the suction cup base 1. By providing a plurality of vacuum vent holes 3, the surface area of ​​the suction cup base 1 for adsorbing the product is expanded, thereby ensuring the stability of adsorption of the electrode to be processed. When in use, one end of the vacuum vent hole 3 is blocked, and the other end is connected to a vacuum generating mechanism, which is convenient for the operator to operate;

[0022] Two adjacent vacuum vent holes 3 are connected through a longitudinal through hole 4, and a plurality of vacuum vent holes 3 arranged in parallel are connected through the longitudinal through hole 4, so that the air pressure in each vacuum vent hole 3 is kept the same, thereby ensuring that the adsorption force at each adsorption hole 6 on the suction cup body is consistent, ensuring the stability of the adsorption of the electrode to be processed, and preventing the electrode from falling off the suction cup base 1;

[0023] The surface of the suction cup base 1 is provided with a plurality of adsorption holes 6 which can be connected downward to the vacuum vent hole 3. The vacuum generating mechanism evacuates the vacuum vent hole 3 to form a negative pressure state between the vacuum vent hole 3 and the inside of the adsorption hole 6, thereby adsorbing the product to be processed on the adsorption hole 6. In some embodiments, the diameter of the adsorption hole 6 is 4 mm.

[0024] The vacuum vent 3 is opened along the length direction of the suction cup base 1, and one end of the upper end is connected to the vacuum generating mechanism, and the other end is blocked by a sealing plug. The vacuum vent 3 is arranged along the length direction of the suction cup base 1 to expand the surface adsorption area. When working, one end of the vacuum vent 3 is blocked, and the other end is connected to the vacuum generating mechanism. It should be noted that in some embodiments, the sealing plug is specifically a rubber plug to ensure that no external air enters the vacuum vent 3 through the blocked gap, thereby avoiding vacuum loss, and the vacuum generating mechanism specifically adopts a vacuum pump or a negative pressure generator.

[0025] In some embodiments, twelve vacuum vent holes 3 are arranged in parallel, and specifically, the diameter of each vacuum vent hole 3 is 16 mm.

[0026] The plurality of longitudinal through holes 4 are located on the same straight line parallel to the width direction of the suction cup base 1. By providing the longitudinal through holes 4, the air pressure in each vacuum vent hole 3 in the suction cup base 1 is kept consistent.

[0027] In some embodiments, two adjacent vacuum vent holes 3 are connected via two longitudinal through holes 4 respectively arranged at the head and tail thereof, and the aperture of the longitudinal through hole 4 is 16 mm, which is consistent with the aperture size of the vacuum vent hole 3 .

[0028] It should be noted that the relative positions of the plurality of longitudinal through holes 4 are not limited, as long as the longitudinal through hole 4 connects two adjacent vacuum vent holes 3 so that the air pressure in each vacuum vent hole 3 remains the same, thereby ensuring that the adsorption force of each adsorption point on the suction cup base 1 is consistent.

[0029] At least one of the two sides of the suction cup base 1 in the length direction is horizontally provided with a fixing hole extending to the inside, and the fixing hole is connected to the longitudinal through hole 4 close thereto. By providing the fixing hole, it is convenient to block the fixing hole before vacuuming the vacuum vent hole 3, thereby ensuring that no external air enters the vacuum vent hole 3 from the longitudinal through hole 4, ensuring that the product can be adsorbed on the surface of the suction cup base 1, and also convenient for the staff to operate to block it.

[0030] In some embodiments, the fixing hole is only provided on one side of the suction cup base 1 and is only connected to the longitudinal through hole 4 closest to this side. It is only necessary to block the fixing hole on this side so that vacuum loss will not occur due to air leakage during the subsequent vacuuming process.

[0031] The suction cup base 1 is provided with a plurality of threaded connection holes 5 penetrating therethrough in the height direction, and the suction cup base 1 and the machine tool workbench are connected by locking bolts passing through the threaded connection holes 5. By providing the threaded connection holes 5, the suction cup base 1 can be fixed on the machine tool workbench, which is convenient for processing the electrode adsorbed on the suction cup base 1. The suction cup base 1 can be quickly disassembled and installed, and the loading and unloading efficiency of the suction cup base 1 is improved. It should be noted that the threaded connection holes 5 and the vacuum vent holes 3 are arranged in a staggered manner.

[0032] In some embodiments, the threaded connection hole 5 has a diameter of 18 mm and is perpendicular to the adsorption surface on the suction cup base 1 .

[0033] The upper surface of the suction cup base 1 is provided with a plurality of positioning threaded holes 7, and a stop plate is connected to each of the positioning threaded holes 7. The stop plate can position the electrode to be processed placed on the suction cup base 1 to ensure the subsequent processing accuracy of the electrode.

[0034] A cooling water channel 8 is horizontally laid on the suction cup base 1 between the vacuum vent hole 3 and its bottom. In some embodiments, a plurality of cooling water channels 8 are arranged parallel to the adsorption surface of the suction cup base 1, and each cooling water channel 8 is respectively provided with a water inlet end and a water outlet end, and the water inlet end and the water outlet end respectively extend out of the side edge in the width direction of the suction cup base 1, so as to facilitate the circulation of water in the cooling water channel 8.

[0035] The cooling water channel 8 is arranged in an S-shaped continuous bend.

[0036] Working principle: When processing a larger PICP electrode, the staff will lay three sucker bases 1 together to form a 3300*3732mm adsorption table. The vacuum vents 3 on two adjacent sucker bodies 1 correspond to each other, and a silicone seal is set in the gap between the connecting sides to ensure that there will be no leakage and vacuum loss during the subsequent vacuum adsorption process. Block one end of the vacuum vent 3, connect the other end to the vacuum generating mechanism, and block the end of the longitudinal through hole connected to the sucker base. When the vacuum generating mechanism is working, negative pressure can be formed in the channel of the vacuum vent. The electrode placed on the adsorption surface of the sucker base can be adsorbed by using the negative pressure and through the adsorption hole, so as to achieve the purpose of fixing the component.

[0037] The above implementation modes are only for illustrating the technical concept and features of the utility model, and their purpose is to allow people familiar with this technology to understand the content of the utility model and implement it. It cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
