Description

Technical Field

[0001] This utility model relates to the field of automated coating equipment technology, and more specifically, to a magnetic quick-release vacuum adhesive suction device. Background Technology

[0002] With the development of processing and manufacturing technology, coating is being used more and more widely in various industries. At the same time, the requirements for coating process capabilities are becoming increasingly stringent, as are the requirements for equipment maintenance, placing higher demands on design. The vacuum suction device in the old module primarily aims to remove excess residual adhesive from the atomizing cap to prevent paint cracking and adhesive breakage during the next spraying. However, it is difficult to maintain, requiring the unscrewing of four screws and then prying it open with a screwdriver. This process is very time-consuming and easily damages the vacuum suction module. Furthermore, the lack of an internal filter allows glue particles to enter the vacuum generator through the air tube, contaminating it. Therefore, the old vacuum suction module has defects. Disassembly efficiency is low: it requires removing four screws and prying it open with tools, which is time-consuming and easily damages the device. Vacuum generator contamination: the lack of a filter design allows glue particles (particle size > 5μm) to directly enter the vacuum generator, increasing the pump failure rate. Insufficient positioning accuracy: repeated disassembly and reassembly cause positioning deviations, leading to misalignment between the nozzle and the atomizing cap, reducing the residual glue removal rate.

[0003] Existing technology has inherent flaws and needs improvement. Utility Model Content

[0021] like Figures 1-4 As shown: A magnetic quick-release vacuum adhesive removal device includes a vacuum suction cavity 1, a vacuum section 2, and a vacuum suction cup cover 3. The vacuum section 2 is disposed inside the vacuum suction cavity 1, and the vacuum suction cup cover 3 is disposed on the vacuum section 2 and connected to the vacuum suction cavity 1. The vacuum suction cavity 1 includes a suction pipe connector 11, a handle position 12, and a positioning hole 13. The suction pipe connector 11 is disposed on one side of the vacuum suction cavity 1. The handle position 12 is installed on the vacuum suction cavity 1 on one side of the vacuum section 2. A positioning block is extended from one side of the vacuum suction cavity 1, and the positioning hole 13 is installed on the positioning block.

[0022] It should be noted that the vacuum suction chamber 1 is designed with a suction pipe connector 11, which is connected to the vacuum generator at the other end. This is used to draw a vacuum inside the vacuum suction chamber 1 to remove residual adhesive from the atomizing cap. The vacuum suction chamber 1 is also designed with a handle 12 and a positioning hole 13, which facilitate the disassembly of the vacuum suction cup cover 3 and the positioning and installation of the vacuum suction chamber 1, respectively. Furthermore, the vacuum suction chamber 1 is designed with a septum plate 21 to prevent residual adhesive from being accidentally sucked into the box-type vacuum suction generator. Inside the septum plate 21 are a sealing ring 23 and an adhesive collection cup 22, which are used to seal the vacuum suction chamber 1 and collect residual adhesive. Above that are magnets, which are symmetrically distributed and are used to magnetically fix the vacuum suction cup cover 3, making it easy to disassemble and clean the empty vacuum cup inside. The vacuum suction cup cover 3 is designed with 4 magnetic suction holes, as well as a buffer pad 34 and a buffer pressure plate 32. Furthermore, this includes using a magnetic fixing structure and increasing the number of urethane cushioning openings. A filter device is installed inside the vacuum suction chamber to prevent particles from entering the vacuum generator through the vacuum suction pipe connector. When maintenance is required, the glue collection cup 22 can be directly removed and automatically sucked in and fixed when placed down, which is very convenient and quick, improves maintenance efficiency, and prevents glue particles from entering the vacuum generator, significantly improving equipment maintainability and coating quality stability. Furthermore, the vacuum generator includes a vacuum mounting plate, a three-way valve, a generator, and a solenoid valve. One side of the vacuum mounting plate is disposed in the vacuum suction cavity, and the three-way valve and the generator are respectively mounted on the other side of the vacuum mounting plate. One end of the suction pipe connector is connected to the vacuum suction cavity, and the other end is connected to one end of the three-way valve. The solenoid valve is installed on the other end of the three-way valve. The bottom end of the three-way valve is connected to one end of the generator through a first pipe, and the other end of the generator is connected through a second pipe. It should be noted that the equipment connects to the air source through the generator, and works with the three-way valve and the suction pipe connector to evacuate the vacuum suction chamber to form a vacuum chamber. The solenoid valve is used to control the opening or closing of the three-way valve, so that the vacuum suction chamber can draw in and allow gas to enter, allowing it to suction glue or allow air to enter under vacuum conditions. The glue suction part can then be removed to remove residual glue.

[0023] Furthermore, the vacuum mounting plate is designed as an L-shaped plate, and the air pipe connector is designed as an L-shaped angle valve.

[0024] Preferably, the vacuum cup lid 3 includes a vacuum cover plate 31, a buffer plate 32 and a plurality of magnets 33. The lower end of the vacuum cover plate 31 is equipped with a plurality of magnets 33 and the buffer plate 32 is installed on the vacuum cover plate 31.

[0026] Preferably, the vacuum cover plate 31 also has four buffer port installation positions, with embedded urethane buffer pads 34, which are located below the buffer pressure plate 32.

[0027] It should be noted that the buffer pad 34 has high elasticity and strong resistance to compression deformation, which can eliminate vacuum suction force and separation resistance.

[0028] Preferably, multiple columns of magnets 33 are embedded in the vacuum cover plate 31, the assembled buffer port, and the buffer pressure plate 32.

[0029] It should be noted that the magnet provides static holding force, while the adhesive buffer provides dynamic sealing compensation, forming a magnetic attraction-elasticity synergistic sealing system.

[0030] Preferably, a locking groove is provided inside the vacuum suction cavity 1, and a locking protrusion is provided at the lower end of the vacuum cover plate 31.

[0031] It should be noted that the locking groove and the locking protrusion are installed opposite each other, and multiple suction holes are installed in the locking groove. The multiple suction holes work in conjunction with multiple magnets 33; they are fixed with epoxy resin adhesive. Furthermore, at least four suction holes and multiple magnets 33 are provided; when the distance between the vacuum cover plate 31 and the vacuum suction cavity 1 is ≤3mm, they automatically adsorb, with a separation force ≥80N, forming a magnetic suction fixing system to improve positioning accuracy.

[0032] Preferably, the vacuum section 2 includes a septum plate 21, a glue collection cup 22, and a sealing ring 23. The septum plate 21 is disposed inside the vacuum suction cavity 1, the glue collection cup 22 is disposed inside the septum plate 21, and the sealing ring 23 is installed on the septum plate 21.

[0033] It should be noted that the glue collection cup 22 is designed with a sealing ring 23 and a glue separator 21 in the middle to prevent residual glue from being accidentally sucked into the box-type vacuum generator. The glue collection cup 22 is used to collect residual glue. The sealing ring 23 and the glue separator 21 form a filter module.

[0034] Preferably, the vacuum suction cavity 1 has multiple handle positions 12, which are respectively located on both sides of the vacuum suction cavity 1.

[0036] Preferably, the depth of the hand-grabbing position 12 is set to 15mm, and the width is set to 5-20mm.

[0037] It should be noted that the width matches the curve of an adult thumb pad, conforming to ergonomics, and the hand-taking position 12 and the positioning hole 13 form a positioning structure.

[0038] Furthermore, the working process of its vacuum residual adhesive removal device is as follows: Installation: Hold the vacuum cover and magnetically align it with the four holes of the vacuum suction chamber 1, and the magnetic attraction will automatically lock it; Adhesive collection: Residual adhesive passes through the buffer port → adhesive collection cup cover → adhesive collection cup 22, and the adhesive separation plate 21 blocks the adhesive particles from rising; Disassembly: Lift the upper handle 12, the urethane buffer port is instantly depressurized, and the magnetic attraction separates the adhesive; Maintenance and cleaning: Pour out the residual adhesive from the adhesive collection cup 22 → clean with thinner → directly reinstall.
