Abstract
Description
Technical Field
[0001] This article belongs to the technical field of automatic labeling machines, specifically an automatic adjustment and correction labeling machine for contact lens outer packaging cups Background Art
[0002] Contact lenses are lenses that attach directly to the tear layer on the surface of the cornea. They alter the eye's refractive power to correct myopia, hyperopia, astigmatism, and treat certain eye diseases. They come in three types: rigid, semi-rigid, and soft, depending on the hardness of the material. After production and processing, they must be stored in PP outer packaging cups. However, as medical devices, regulations require that each lens label be adhered to the top surface of the PP cup. Before the PP cups are finally boxed, a labeling machine is used to apply the corresponding lens parameters and specifications.
[0003] However, due to the material of the stickers themselves, the stickers are all pasted in rolls on the adhesive backing roll. The stickers are drawn out one by one through a discharging machine to facilitate automatic pasting. In the existing automatic pasting process, a fixed small robotic arm is used to remove the stickers from the adhesive backing and press them down to the top cover of the PP cup.
[0004] However, if you remove the sticker directly in this way, the sticker will shift during the process of removing the sticker due to the vibration of the robot arm and the adhesive damping on the backing. These shifted positions are usually irregular, which will cause the sticker to shift during the pasting process of the robot arm. Because the PP cup itself is small in size and each PP cup needs to be pasted, the sticker is completely covered on the surface of the PP cup. The content of the sticker is also large and dense, and the sticker shift cannot be avoided by shrinking the sticker. Therefore, when the sticker shifts, it will leak from the top surface of the PP cup to form a corner, thus resulting in defective products. Utility Model Content
[0005] In order to solve the above problems, this paper proposes an automatic adjustment and correction labeling machine for contact lens outer packaging cups. The labeling machine is a disc automatic circulation labeling machine. The upper surface of the base of the labeling machine is provided with a tooling turntable. The outside of the tooling turntable in the middle of the labeling machine is provided with a feeding component, a discharging component and a labeling component. The labeling machine is arranged between the feeding component and the discharging component. The labeling component includes a sticker discharging machine, a sticker position camera and a multi-axis robotic arm. The sticker discharging machine is horizontally arranged on the left side of the horizontal center line of the tooling turntable. The right end of the sticker discharging machine is provided with a lead-out plate. The lead-out plate is arranged above the upper surface of the tooling turntable. There is a gap between the lead-out plate and the left side of the tooling turntable. A sticker position camera is provided below the gap between the lead-out plate and the tooling turntable. The sticker position camera is vertically upwardly arranged on the surface of the base A multi-axis robotic arm is provided above the sticker position camera, and the multi-axis robotic arm is provided on the outside of the tooling turntable, and the axial direction of the multi-axis robotic arm is fixedly provided on the upper surface of the base, and the clamping claws of the multi-axis robotic arm move horizontally in parallel between the lead-out plate and the right side of the tooling turntable. By additionally adding a labeling component capable of controlling the label position on the outside of the existing automated turntable labeling machine, a sticker position camera and a multi-axis robotic arm are provided between the sticker discharging machine and the adjacent tooling turntable, and the position of the sticker taken out by the multi-axis robotic arm is directly determined by the sticker position camera based on the clamping claw of the robotic arm, and the position of the sticker is linked and adjusted by the robotic arm, so as to ensure that the position of the sticker is accurately pasted to the upper surface of the contact lens cup body, and the sticker will not be skewed, thereby improving the overall automated pasting accuracy.
[0006] The base is in the shape of a horizontal rectangular table top, and a tooling turntable is provided on the right side of the horizontal axis of the upper surface of the base. The shape of the tooling turntable is a circular turntable, and a plurality of positioning grooves are provided in a circular and equidistant manner on the outer edge of the upper surface of the tooling turntable. The shape of the positioning grooves is nested with the outer packaging cup. By using a tooling table that rotates in equidistant sections, the positioning grooves above the tooling table can be rotated in sections at fixed angles, thereby realizing cyclic automated production and efficient automated operation.
[0007] A feed conveyor is provided vertically in the front of the tooling turntable, and a discharging conveyor is provided vertically in the right side of the tooling turntable. A feeder is provided on the left side of the feed conveyor, and a discharging machine is provided on the right side of the discharging conveyor. Both the feeder and the discharging machine are rotating and translational material picking arms, and the front ends of the feeder and the discharging machine are vertically provided with vacuum suction heads. By respectively arranging the feeding assembly and the discharging assembly on the front side and the right side of the tooling turntable, automatic feeding and discharging in the form of a conveyor belt can be realized, and automatic clamping feeding and discharging into the tooling turntable can also be realized through the feeder and the discharging machine, thereby realizing the automatic operation of the entire tooling turntable.
[0008] A sticker discharging machine is horizontally provided on the left side of the tooling turntable. The sticker discharging machine is a self-winding sticker machine. A material roll is provided on the upper left side of the sticker discharging machine, and a waste roll is provided below the material roll of the sticker discharging machine. A lead-out plate is provided horizontally on the right side of the waste pipe of the sticker discharging machine. The material roll is cyclically connected to the waste roll through the lead-out plate. The sticker discharging machine arranged on the left side of the tooling turntable realizes self-discharging and self-retracting stickers, and can also lead out the corresponding stickers separately through the lead-out plate, which is convenient for the multi-axis robot arm to perform planar suction. A gap is also provided between the lead-out plate and the tooling turntable to facilitate camera detection.
[0009] The sticker position camera is a flat angle camera. The lens of the sticker position camera is vertically installed between the sticker discharger and the tooling table. The sticker camera is connected to the multi-axis robotic arm through a wire. By setting the sticker position camera below the sticker discharger and the tooling turntable, the position of the removed stickers can be detected from bottom to top, so that the multi-axis robotic arm can be controlled in conjunction to perform automatic adjustments to ensure the accuracy of sticker pasting.
[0010] The multi-axis robotic arm is a linkage-controlled robotic arm. A flat suction head is provided at the end of the multi-axis robotic arm. The bottom area of the flat suction head is larger than the area of the sticker. The multi-axis robotic arm vacuum-sucks the top surface of the sticker through the flat suction head. The color depth of the flat suction head is greater than the color depth of the bottom surface of the sticker. The multi-axis robotic arm can realize multi-angle automatic adjustment after the sticker is taken up, and the flat suction head can conveniently clamp the flat flexible material such as the sticker in a flat manner. The dark-colored flat suction head can effectively improve the detection effect of the sticker by the camera, and can accurately detect the offset angle of the sticker.
[0011] Beneficial effects:
[0012] By adding an additional labeling component that can control the label position on the outside of the existing automated turntable labeling machine, a sticker position camera and a multi-axis robotic arm are set between the sticker discharging machine and the adjacent tooling turntable. The sticker position camera directly determines the position of the sticker taken out by the multi-axis robotic arm based on the gripper of the robotic arm, and then the robotic arm is linked to make adjustments, thereby ensuring that the sticker is accurately positioned on the upper surface of the contact lens cup body without being skewed, thereby improving the overall automated pasting accuracy.
[0013] By using a tooling table that rotates in equidistant segments, the positioning slots above the tooling table can be rotated in segments at fixed angles, thereby realizing cyclic automated production and efficient automated operation.
[0014] By arranging the feeding assembly and the discharging assembly on the front side and the right side of the tooling turntable respectively, automatic feeding and discharging can be achieved through the conveyor belt. In addition, the feeding machine and the discharging machine can be used to realize automatic clamping feeding and discharging into the tooling turntable, thereby realizing the automatic operation of the entire tooling turntable.
[0015] The sticker discharger set on the left side of the tooling turntable can realize the self-discharging and self-collecting of stickers, and can also lead out the corresponding stickers individually through the lead-out plate, which is convenient for the multi-axis robot arm to carry out flat suction. There is also a gap between the lead-out plate and the tooling turntable to facilitate camera detection.
[0016] By setting a sticker position camera below the sticker discharging machine and the tooling turntable, the position of the removed stickers can be detected from bottom to top, so that the multi-axis robotic arm can be controlled to perform automatic adjustments to ensure the accuracy of sticker pasting.
[0017] The multi-axis robotic arm can realize multi-angle automatic adjustment after sticker picking, and the flat suction head can easily clamp flat flexible materials such as stickers. The dark flat suction head can also effectively improve the detection effect of stickers by the camera and accurately detect the offset angle of the sticker. BRIEF DESCRIPTION OF THE DRAWINGS
