Description

Technical Field

[0001] The utility model relates to the field of appearance detection, in particular to an oiling device for roller appearance detection. Background Art

[0002] The appearance inspection of rollers requires 100% inspection. Currently, a deep vision appearance inspection machine is used to inspect the appearance of rollers.

[0003] Rollers need to be oiled before appearance inspection. The existing roller oiling is carried out by placing the rollers on a double-speed chain conveyor and spraying oil on the rollers with a flat nozzle. The flat nozzle spraying oil will cause uneven oiling on the outer diameter surface of some rollers, and there will be excess oil or no oil on the outer diameter surface of the roller, especially for rollers with large taper angles and large aspect ratios. The outer diameter surface of the roller is unevenly oiled, and the nozzle cannot clean the dirt on the outer diameter surface of the roller when spraying. When the appearance inspection machine is inspecting, if the outer diameter surface of the roller has too much oil, no oil, or there is dirt on the outer diameter surface of the roller, misjudgment will occur, affecting the inspection quality and efficiency, and increasing the rework and repair rate of defective products.

[0004] Based on the above technical problems, the present application provides an oiling device for roller appearance inspection. Utility Model Content

[0005] The utility model aims to provide an oiling device for roller appearance inspection, which solves the problem that the existing roller is unevenly oiled and has no function of cleaning dirt, resulting in a high number of misjudgments by the appearance inspection machine.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an oiling device for roller appearance inspection, including a device body, the device body including a cross beam plate, two supporting longitudinal plates vertically and correspondingly arranged at the bottom end of the cross beam plate, an installation cavity is formed between the two supporting longitudinal plates, a sponge block is arranged in the installation cavity, an oil groove is opened on the cross beam plate, and the oil groove corresponds to the top of the sponge block.

[0007] Preferably, the sponge block consists of a first sponge block and a second sponge block stacked up and down, thereby extending the oiling time.

[0008] Preferably, gauze is provided between the first sponge block and the second sponge block to reduce the speed of oil seepage and prolong the oil application time.

[0009] Preferably, a height-adjustable sponge fixing mechanism is provided on the inner side of the supporting longitudinal plate, which has an adjustment function.

[0010] Furthermore, the supporting mechanism includes a through slot vertically opened on the supporting longitudinal plate, a fixing strip arranged on the inner side of the through slot, a gasket arranged on the outer side of the supporting longitudinal plate, and a locking bolt passing through the through slot; the gasket and the fixing strip are fixed by the locking bolt; both sides of the first sponge block and the second sponge block are provided with a slot matching with the fixing strip; the angle of the fixing strip can be adjusted to make the angle of the sponge block adjustable.

[0011] Furthermore, magnets are provided at the bottom ends of the two supporting longitudinal plates, so that the oiling device can be quickly fixed.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] 1. The utility model adds a device body before each station inspection of the appearance inspection machine. When the roller passes through, the outer diameter surface of the roller contacts the first sponge block, so that the bottom end of the first sponge block applies oil to the outer diameter surface of the roller, so that the oil is evenly applied to the outer diameter surface of the roller, and the excess oil on the outer surface of the roller is wiped off. At the same time, the dirt on the outer diameter surface of the roller is wiped off to ensure the cleanliness of the roller, reduce the misjudgment rate of the appearance inspection machine, and improve the pass rate and production efficiency.

[0014] 2. The utility model provides a through groove, and can adjust the position and angle of the fixing strip according to the roller taper angle and aspect ratio, so that the first sponge block is in contact with the outer diameter surface of the roller, ensuring that the oil is evenly applied to the outer diameter surface of the roller.

[0015] 3. The first sponge block and the second sponge block of the utility model are stacked, so that the oil in the upper second sponge block can slowly seep into the lower first sponge block, which can extend the time for the first sponge block to be oiled;

[0016] A layer of gauze is laid between the first sponge block and the second sponge block. Since the fiber structure of the gauze can effectively prevent the penetration of water, the water will be absorbed by the fibers when passing through the gauze, thereby slowing down the flow rate of the water, extending the wiping time of the first sponge block, and avoiding excessive oiling of the roller surface.

DETAILED DESCRIPTION

[0022] See also Figures 1 to 4 A roller appearance inspection oiling device includes a device body, the device body includes a cross beam plate 1, two supporting longitudinal plates 2 vertically and correspondingly arranged at the bottom end of the cross beam plate 1, a mounting cavity 3 is formed between the two supporting longitudinal plates 2, a sponge block is arranged in the mounting cavity 3, an oil groove 5 is opened on the cross beam plate 1, and the oil groove 5 corresponds to the top of the sponge block.

[0023] The sponge block is composed of a first sponge block 4 and a second sponge block 6 stacked up and down.

[0024] Gauze 7 is arranged between the first sponge block 4 and the second sponge block 6 .

[0025] A height-adjustable sponge fixing mechanism is arranged on the inner side of the supporting longitudinal plate 2 .

[0026] The supporting mechanism includes a through slot 8 vertically opened on the supporting longitudinal plate 2, a fixing strip 9 arranged on the inner side of the through slot 8, a gasket 10 arranged on the outer side of the supporting longitudinal plate 2, and a locking bolt 11 passing through the through slot 8; the gasket 10 and the fixing strip 9 are fixed by the locking bolt 11; both sides of the first sponge block 4 and the second sponge block 6 are provided with a card slot 12 that matches the fixing strip 9.

[0027] Magnets 13 are disposed at the bottom ends of the two supporting longitudinal plates 2 .

[0028] The working principle of the utility model is:

[0029] The double-speed chain conveyor 14 transports the roller 17 to each station of the appearance inspection machine for inspection. The device body is arranged before the inspection of each station of the appearance inspection machine. The sponge block is located above the roller 17 transported by the double-speed chain conveyor 14, so that the sponge block can oil the passing roller 17.

[0030] The specific working process of the utility model device body is:

[0031] The symmetrically arranged supporting longitudinal plates 2 support and fix the cross beam plate 1. The two supporting longitudinal plates 2 and the cross beam plate 1 form a U-shaped frame. The sponge block is installed in the installation cavity 3. When the roller 17 to be tested is transported on the double-speed chain conveyor 14, the bottom end of the roller 15 on the double-speed chain contacts the bottom end of the inner side of the guide rail 16, and the roller 15 rotates, so that the roller 17 also rotates during transportation, which can ensure that the outer diameter surface of the roller 17 contacts the sponge block, so that the bottom end of the sponge block oils the outer diameter surface of the roller 17, and the oil is evenly applied to the outer diameter surface of the roller 17, and the excess oil on the outer surface of the roller 17 is wiped off. At the same time, the dirt on the outer diameter surface of the roller 17 is wiped off to ensure the cleanliness of the roller 17, reduce the misjudgment rate of the appearance inspection machine, and improve the pass rate and production efficiency.

[0032] The first sponge block 4 and the second sponge block 6 of the utility model are stacked. When the oil passes through the stacked second sponge block 6 and the first sponge block 4, it needs to overcome more resistance. These resistances come from the air resistance and capillary action in the gaps between the sponge blocks. These resistances increase the flow resistance of the oil, resulting in a decrease in the seepage speed, which can extend the time for the first sponge block 4 to apply oil;

[0033] The utility model lays a layer of gauze 7 between the first sponge block 4 and the second sponge block 6. Since the fiber structure of the gauze 7 can effectively prevent the penetration of water, the water will be absorbed by the fibers when passing through the gauze 7, thereby slowing down the flow rate of the water, which can further reduce the speed of the oil in the second sponge block 6 to seep downward, prolong the wiping time of the first sponge block 4, and avoid excessive oiling of the surface of the roller 17.

[0034] The working principle of the support mechanism of the utility model is:

[0035] The utility model uses bolts 11 and washers 10 to position the fixing strip 9, and the slots 12 on both sides of the first sponge block 4 and the second sponge block 6 are snapped onto the fixing strip 9, so that the first sponge block 4 and the second sponge block 6 can be installed. By opening the through slot 8, the position and angle of the fixing strip 9 can be adjusted, so that the position and angle of the first sponge block 4 and the second sponge block 6 can be adjusted, and the position and angle of the fixing strip 9 can be further adjusted according to the cone angle and the aspect ratio of the roller 17. The angle adjustment range of the fixing strip 9 is 2-4°, so that the first sponge block 4 is in contact with the outer diameter surface of the roller 17, ensuring that the oil is evenly applied to the outer diameter surface of the roller 17.

[0036] The utility model provides an oil groove 5 on the cross beam plate 1, and the oil groove 5 is convenient for adding oil to ensure the humidity of the sponge block (the humidity of the sponge block is 70%).

[0037] The utility model is provided with a magnet 13 at the bottom end of the supporting longitudinal plate 2, and the device body can be adsorbed on the machine tool under the action of magnetic force, so that the device body can be quickly adjusted and installed.

[0038] The roller 17 of the present invention passes through the direction of the sponge block. The length of the sponge block of the present invention is twice the circumference of the roller 17 , and the width of the sponge block is greater than the length of the roller 17 .

[0039] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
