Detailed Description

The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that any combination of the embodiments or technical features described below can be used to form a new embodiment without conflict.

Referring to fig. 1, the present embodiment discloses a method for rejecting damaged mask pieces, which is performed on the device for rejecting damaged mask pieces shown in fig. 2 to 5, and can automatically detect whether a mask output by a mask production line is damaged or not, and reject the damaged mask, thereby improving the production efficiency of the mask and ensuring the quality of the output mask.

Step S1: receiving detection data sent by detection equipment arranged at the tail end of a production line in real time;

when gauze mask transported to terminal position on the gauze mask production line and passed through the check out test set of bad piece remove device of gauze mask, check out test set can shoot the gauze mask of transporting on the production line through the camera 1 who installs in the terminal top of production line in order to obtain outward appearance surface data to the light beam that sends through backlight 2 shines on camera 1 through the damaged department of gauze mask in order to obtain interval detection data. The detection device transmits detection data such as appearance surface data and spacing detection data to the controller for processing.

The detection equipment comprises a camera 1 which is installed above the tail end of the mask production line through a fixed seat, the detection direction of the camera 1 faces downwards and is perpendicular to the transportation direction of the mask, and the shooting view field of the camera 1 is adjusted before the detection equipment is put into use, so that the mask produced through the mask production line can be completely shot; when the mask passes through the camera 1, the camera 1 shoots the mask, the camera 1 transmits the shot picture to a controller connected with the camera 1, and the controller processes the shot picture to obtain mask appearance surface data, wherein in the embodiment, the appearance surface data comprises mask width, mask length, mask appearance shape and the like; and then the controller compares the appearance surface data with pre-recorded mask size data, so as to judge whether the mask appearance meets the set standard.

In addition, the detection equipment also comprises a backlight source 2 which is arranged below the tail end of the production line and is opposite to the position of the camera 1, and the light emitting surface of the backlight source 2 faces upwards, so that the light emitted by the backlight source 2 can irradiate on the mask; correspondingly, the camera 1 can also receive the light emitted by the backlight 2, so as to obtain the distance detection data from the backlight 2 to the camera 1, and transmit the distance detection data to the controller, so as to judge that the mask is damaged: if the gauze mask is complete qualified gauze mask, the light beam that backlight 2 sent then can be sheltered from by the gauze mask, camera 1 then can't acquire interval detection data, if damaged appears in arbitrary position of gauze mask, the light that backlight 2 sent then can see through gauze mask damage department shine on camera 1, consequently, if camera 1 received interval detection data when the gauze mask process, then can judge that this gauze mask appears damaged and mark as nonconforming product.

Step S2: and judging whether the mask meets the set standard or not according to the detection data.

Firstly, calling detection data, judging whether the distance detection data is received or not when the mask passes through the detection equipment, if so, indicating that the mask is damaged, and then calibrating the mask as an unqualified product; if not, judging whether the detected data such as the mask size, the mask appearance and the like are in accordance with the preset mask size standard or not according to the appearance surface data, namely judging that the mask is an unqualified product if the data are not in accordance with the preset mask size standard, and executing the step S3; if the mask is qualified, the mask can be transported through the mask production line continuously, and finally output from the tail end of the production line.

Step S3: when judging that gauze mask quality is unqualified, generate and reject the instruction to on will rejecting the instruction and sending to the removing devices 4 who installs on the production line end, control removing devices 4 with perpendicular to production line on the angle of gauze mask direction of transportation push down, will not conform to the gauze mask of setting for the standard and push down until the gauze mask breaks away from the production line, the gauze mask drops in collection box 3 this moment.

The removing device 4 on the mask production line is located in front of the camera 1 in the mask conveying direction, the mask reaches the removing device 4 after being shot by the camera 1 in the mask conveying process, and if the detecting equipment detects that the mask is unqualified, the controller controls the removing device 4 to press the mask downwards to enable the mask to leave the mask production line; if the quality of the mask is qualified, the rejecting device 4 does not work when the mask is transported to the rejecting device 4, and the mask is still transported through a mask production line until the mask is transported out from the mask output part at the tail end of the production line.

The removing device 4 comprises a first pushing plate 41 and a driving device, in this embodiment, the driving device is a linear push rod motor 42, a fixed end of the linear push rod motor 42 is erected right above the end of the mask production line through a first bracket 45, a movable end of the linear push rod motor 42 penetrates through an opening on the first bracket 45 and is connected with the first pushing plate 41, so that the first pushing plate 41 can be erected right above the mask production line, when the linear push rod motor 42 is driven, the movable end of the linear push rod motor 42 drives the first push plate 41 to move up and down in a reciprocating manner at an angle perpendicular to the mask conveying direction, that is, the linear push rod motor 42 can drive the first pushing plate 41 to ascend or to press down, and the mask on the mask production line can be pressed down in the process of pressing down the first pushing plate 41, so that the mask is separated from the production line to achieve the effect of removing the mask.

And a recovery box 3 is arranged below the mask production line at the position facing the first pushing plate 41, and after the mask is pressed down by the first pushing plate 41, the mask can fall into the recovery box 3 to be collected.

Guide rods 43 are fixed on two sides of the first pushing plate 41 respectively, the guide rods 43 are perpendicular to the surface of the first pushing plate 41, openings are formed in positions, corresponding to the guide rods 43, of the first support 45, bearings 44 are arranged at the openings, rods of the guide rods 43 penetrate through the bearings 44 and extend to the upper portion of the first support 45, so that when the first pushing plate 41 moves up and down, the guide rods 43 limit the movement track of the first pushing plate 41, the first pushing plate 41 is not deviated, the first pushing plate 41 and a mask on a mask production line are always kept in a parallel state, and the movement stability of the first pushing plate 41 is improved.

In order to avoid the influence of the movement of the first pushing plate 41 on the normal operation of the mask production line, a pressing piece transmission assembly for transporting the mask is arranged at the tail end of the mask production line. The pressing piece transmission assembly comprises four transmission rings, each transmission ring is driven by a rotating shaft and a motor, and each transmission ring can rotate around the rotating shaft under the drive of the motor. The four transmission rings comprise a first transmission ring 7, a second transmission ring 8, a third transmission ring 9 and a fourth transmission ring 10, wherein the first transmission ring 7 and the second transmission ring 8 are sequentially arranged up and down, and the lower surface of the first transmission ring 7 and the upper surface of the second transmission ring 8 are stacked up and down and are positioned on the same side of the mask production line; similarly, the third transmission ring 9 and the fourth transmission ring 10 are stacked up and down and positioned at the other side of the mask production line; the transmission ring of gauze mask production line both sides piles up the department and can be used for the both ends of centre gripping gauze mask respectively, can centre gripping gauze mask transport when four transmission ring synchronous rotation. Meanwhile, the width of the transmission rings is smaller, and the distance between the transmission rings on two sides in the mask production line is larger than the length of the first pushing plate 41, so that the influence of the first pushing plate 41 touching the transmission rings when being pressed down on the normal operation of the mask production line can be avoided.

A conveyor belt 6 is arranged right below the mask output end at the tail end of the mask production line and is used for conveying masks output from the mask production line; and a certain gap is formed between the front end of the conveyor belt 6 and the backlight source 2, and the gap is larger than the width of the first pushing plate 41, so that when the abnormal mask is pressed down by the first pushing plate 41, the first pushing plate 41 does not touch the backlight source 2 and the conveyor belt 6.

The second pushing device 5 is arranged at the tail end of the mask production line, and the structure of the second pushing device 5 is the same as that of the first pushing plate 41, but the installation positions are different. The second pushing device 5 comprises a second pushing plate 51 and a driving device, the second pushing plate 51 is erected at the tail end of the mask production line at the mask output end through a second bracket 52 and is positioned in front of the rejecting device 4 in the mask conveying direction; the driving device is connected with the second pushing plate 51 and drives the second pushing plate 51 to move up and down in a reciprocating mode at an angle perpendicular to the conveying direction of the masks on the production line, so that the masks output by the mask production line are pressed down onto the conveying belt 6 through the second pushing plate 51, and the masks can be orderly arranged on the conveying belt 6 to be conveyed.

Because gauze mask transport speed is very fast on the gauze mask production line, in order to improve rejecting device 4 and second pusher 5's agility first pushing plate 41 with second pushing plate 51 all is equipped with a plurality of through-holes on the surface, and a plurality of through-holes can reduce first pushing plate 41 and second pushing plate 51's weight for rejecting device 4 and second pusher 5's motion is more quick more.
