Description

Technical Field

[0001] The utility model belongs to the technical field of automation equipment, and in particular relates to an oil suction device. Background Art

[0002] During the production of mobile phone screens, the screens are often subjected to stress tests. During the stress test, developer is sprayed onto the screen. Therefore, the developer needs to be recovered or wiped clean after the test.

[0003] Currently, conventional methods for removing developer are mainly wiping and transferring to a cleaning machine for cleaning. The wiping removal method is prone to scratching the product. In addition, since laser code binding is required immediately after the stress test is completed, the transfer cleaning machine does not meet the subsequent process requirements. At the same time, both wiping removal and transfer cleaning machines will result in waste of developer. Utility Model Content

[0004] The purpose of the utility model is to provide an oil suction device to solve the technical problems described in the background technology.

[0005] The oil suction device includes a frame and an oil collecting bottle. The frame is equipped with an oil suction station. The oil suction station is provided with an oil suction groove for covering the surface of the product. The outer periphery of the oil suction groove is provided with a dust-free cloth pressure plate covering the outer periphery of the product to form a vacuum cavity between the oil suction groove and the product surface. The oil suction groove is connected to the oil collecting bottle through a vacuum pipe, and the vacuum pipe is provided with a vacuum generator.

[0006] According to the technical solution, the utility model can achieve the following beneficial effects:

[0007] 1. Because the outer periphery of the oil suction tank is provided with a dust-free cloth pressing plate that covers and presses against the outer periphery of the product, a vacuum cavity is formed between the oil suction tank and the product surface. Therefore, when the vacuum generator evacuates the oil suction tank through the vacuum pipe, the air outside the product enters the oil suction tank from the outer periphery of the product through the gap of the dust-free cloth pressing plate, so that the oil suction tank can stably and efficiently absorb the developer covering all parts of the product surface.

[0008] 2. Since there is no need to contact the product surface when absorbing the developer on the product surface, there will be no scratches on the product surface. At the same time, there is no need to use liquid to clean the product, so it will not affect the subsequent process requirements;

[0009] 3. Since the oil suction tank is connected to the oil collecting bottle through a vacuum pipe, the developer on the surface of the product can be recovered when it is sucked, thereby avoiding waste of developer.

[0010] In order to further optimize the above technical solution, it can be optionally combined with one or more of the following implementation methods without conflict.

[0011] In some embodiments, the frame is installed with a lifting cylinder, which drives a lifting platform. The oil suction station is located on the lifting platform. The lifting cylinder is used to drive the lifting platform to drive the dust-free cloth pressing plate to press the periphery of the product.

[0012] According to the technical solution, after the product is placed in the position corresponding to the oil absorption station, the lifting cylinder drives the lifting platform to drive the dust-free cloth pressure plate to press against the periphery of the product to fix the product, so that the oil absorption tank can absorb the developer on the surface of the product more stably.

[0013] In some embodiments, at least two oil suction stations are provided on the lifting platform; according to the technical solution, it is possible to simultaneously absorb the developer from multiple products, thereby further improving efficiency.

[0014] In some embodiments, the oil suction station is provided with a photoelectric detection device for detecting whether the dust-free cloth pressing plate is aligned with the periphery of the product;

[0015] According to the technical solution, the lifting cylinder can drive the lifting platform more stably and accurately to drive the dust-free cloth pressure plate to press on the periphery of the product. At the same time, it can avoid damage caused by the dust-free cloth pressure plate being misplaced and pressed on the periphery of the product.

[0016] In some embodiments, an oil suction device further includes a transverse screw module, the transverse screw module being used to drive the frame to move laterally until the dust-free cloth pressing plate is aligned with the periphery of the product;

[0017] According to the technical solution, when the product is transferred to the top or bottom of the oil suction station, the frame is driven by the transverse screw module to move horizontally until the dust-free cloth pressure plate is aligned with the periphery of the product. Therefore, when the utility model is applied to an automated production line, the lifting cylinder can stably and accurately drive the lifting platform to drive the dust-free cloth pressure plate to be pressed against the periphery of the product.

[0018] In some embodiments, an oil suction device further comprises a conveying line, the conveying line being located above the oil suction station, the conveying line supporting both sides of the product and being used to transport the product to above the oil suction station;

[0019] According to the technical solution, after the conveyor line transfers the product to the top of the oil absorption station, the developer on the surface of the product can droop down into the oil absorption tank by its own weight, thereby enabling the oil absorption tank to absorb the developer more efficiently.

[0020] In some embodiments, a limiter is provided above the conveyor line for limiting the rise of the product;

[0021] According to the technical solution, when the lifting cylinder drives the lifting platform to drive the dust-free cloth pressure plate to rise and press on the periphery of the product, the limiter restricts the product from rising, so that the dust-free cloth pressure plate can stably cover the periphery of the product.

[0028] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail with reference to the accompanying drawings. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessary confusion of the concept of the present invention.

[0029] like Figures 1 to 3 As shown, this specific embodiment provides an oil suction device, which includes a transverse screw module 13, an oil collecting bottle 2 and a conveying line 4.

[0030] The transverse screw module 13 drives the frame 1, which is equipped with a lifting cylinder 11. This cylinder drives the lifting platform 12, which is equipped with at least two oil suction stations 3. Each station 3 is equipped with an oil suction trough 31 and a detection photoelectric device 34. The trough 31 is designed to cover the surface of the product 5. A dust-free cloth pressure plate 32 is installed on the outer periphery of the trough 31, which presses against the outer periphery of the product 5. When the trough 31 is applied to the surface of the product 5, a vacuum chamber 33 is formed between the trough 31 and the surface of the product 5. The detection photoelectric device 34 is used to detect whether the dust-free cloth pressure plate 32 is aligned with the outer periphery of the product 5. The trough 31 is connected to the oil collection bottle 2 via a vacuum pipe 21, which is equipped with a vacuum generator 22.

[0031] The conveyor line 4 is located above the oil suction station 3 . The conveyor line 4 carries both sides of the product 5 and is used to transport the product 5 to above the oil suction station 3 . A limiter 41 is provided above the conveyor line 4 to limit the rise of the product 5 .

[0032] The following is a working description of the oil suction device described in this specific embodiment.

[0033] The conveyor line 4 transfers the product 5 to the top of the oil absorption station 3; thereafter, the detection photoelectric 34 searches for the position of the product 5, and the transverse screw module 13 drives the frame 1 to move horizontally until the dust-free cloth pressure plate 32 is aligned with the outer periphery of the product 5; thereafter, the lifting cylinder 11 drives the lifting platform 12 to drive the dust-free cloth pressure plate 32 to rise and press it on the outer periphery of the product 5, and the limiter 41 limits the rise of the product 5. At this time, the oil absorption groove 31 and the surface of the product 5 form a vacuum cavity 33; thereafter, the vacuum generator 22 vacuums the oil absorption groove 31 through the vacuum pipe 21. At this time, the air around the product 5 enters the oil absorption groove 31 from the outer periphery of the product 5 through the gap of the dust-free cloth pressure plate 32, so that the oil absorption groove 31 can absorb the developer covering all parts of the surface of the product 5, and the developer is input into the oil collecting bottle 2 through the vacuum pipe 21 for recovery. After the developer on the product surface is absorbed, the lifting cylinder 11 drives the lifting platform 12 to drive the dust-free cloth pressing plate 32 to descend and reset. At this time, the dust-free cloth pressing plate 32 is separated from the product 5; thereafter, the conveyor line 4 sends the product 5 away.

[0034] In addition, when the vacuum generator 22 evacuates the oil suction tank 31 through the vacuum pipe 21, the vacuum generator 22 can atomize the developer, and then the atomized developer can be turned back into liquid through the oil collecting bottle 2, which is provided with an exhaust pipe.
