Description

TECHNICAL FIELD

[0001] The utility model relates to cup cover processing equipment technical field, concretely relates to a cup cover automatic label sticking manipulator. BACKGROUND

[0002] The cup cover is a component for covering the cup mouth, and is commonly used in beverage cups, vacuum cups and other containers. The main functions include spilling prevention, heat preservation, dust prevention, etc. Cup cover labeling is an important means for brand promotion, information transmission, compliance management and user experience improvement. Through labeling, enterprises can better meet market demand, enhance product competitiveness, and provide users with more comprehensive product information and use guidance. At present, after the cup cover is processed by injection molding, the cup cover needs to be labeled.

[0003] For example, in the Figure 7 structure diagram of a cup cover automatic label sticking manipulator in the prior art, a displacement mechanism is provided, a connecting plate is installed at the bottom end of the displacement mechanism, a rotating shaft in a vertical state is rotatably installed on the connecting plate, an installation block is fixedly installed at the bottom of the rotating shaft, a motor one for driving the rotating shaft to rotate is fixedly installed on the connecting plate, a negative pressure suction cup for negative pressure positioning of the signboard is fixedly installed at the free end of the installation block. When in use, the motor one, the displacement mechanism and the negative pressure suction cup are used to transfer the signboard in the external signboard storage box to the external glue spraying mechanism, spray glue on the signboard sticking surface through the external glue spraying mechanism, and then transfer the signboard to the injection molding machine. The motor one, the displacement mechanism and the negative pressure suction cup are used to paste the signboard sprayed with glue on the surface of the cup cover to achieve the labeling effect of the cup cover.

DETAILED DESCRIPTION

[0033] In order to make the purpose, technical scheme and advantage of the utility model embodiment more clear, the technical scheme in the utility model embodiment is described clearly and completely, obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiment. Based on the embodiment in the utility model, all other embodiments obtained by the person skilled in the art without making the creative labor are within the protection scope of the utility model.

[0034] Embodiment one

[0035] To solve the technical problems in the background art, the following cup cover automatic labeling mechanical hand is given:

[0036] In combination Figures 1-6 The utility model provides a cup cover automatic labeling mechanical hand, including:

[0037] Displacement mechanism 1, the bottom of displacement mechanism 1 is installed with connecting plate 2, displacement mechanism 1 is used for the horizontal direction and vertical direction displacement of connecting plate 2 to displacement mechanism 1,

[0038] Mounting block 3, connecting plate 2 is rotatably installed with the vertical shaft 21 of vertical shape, and the mounting block 3 is fixedly installed at the bottom of the vertical shaft 21, and the connecting plate 2 is fixedly installed with the motor one 22 for driving the vertical shaft 21 to rotate, and the free end of the mounting block 3 is fixedly installed with the negative pressure suction disc 31 for the negative pressure positioning of the signboard 32, and the negative pressure suction disc 31 is connected with the external negative pressure pump;

[0039] Guide rail 4, it is fixedly installed at the top of mounting block 3, and the both ends of guide rail 4 extend to the both sides of mounting block 3 respectively, and the sliding block 41 is slidably connected on the guide rail 4, and the connecting mechanism 5 is installed on the sliding block 41 and above the negative pressure suction disc 31, and the other end of the connecting mechanism 5 is installed with the fixed block 6, and the vertical glue roller 61 is rotatably installed on the fixed block 6, and the glue roller 61 is connected with the glue supply end of the external glue supply equipment, when the sliding block 41 displaces along the guide rail 4, the glue roller 61 can be contacted with the side of the signboard 32 away from the negative pressure suction disc 31;

[0040] Drive mechanism 7, it is installed on the mounting block 3 and is connected with the sliding block 41, and the drive mechanism 7 is used for making the sliding block 41 slide or stop sliding along the guide rail 4.

[0041] In use, the displacement mechanism 1 moves the connecting plate 2, and the motor 22 rotates the shaft 21 on the connecting plate 2, so that the negative pressure suction cup 31 faces the external storage box used to store the sign 32. At this time, the displacement mechanism 1 moves the mounting block 3 closer to the storage box, so that the negative pressure suction cup 31 comes into contact with the sign 32 inside the storage box. With the cooperation of the external negative pressure pump, the negative pressure suction cup 31 can be used to position the sign 32 inside the storage box under negative pressure. Then, with the cooperation of the motor 22 and the displacement mechanism 1, the sign 32 is moved towards the injection molding machine. During this process, the glue application roller 61 is coated with glue by the external glue supply equipment. The adhesive is supplied to the surface, and the sliding block 41 slides along the guide rail 4 via the drive mechanism 7. This causes the adhesive roller 61 to move via the connecting mechanism 5 and the fixing block 6. During this process, the adhesive roller 61 contacts the side of the label 32 away from the negative pressure suction cup 31, thereby achieving the effect of applying adhesive to the adhesive roller 61 on the adhesive surface of the label 32. This replaces the method of transferring the label 32 to an external adhesive spraying mechanism for adhesive spraying. During the labeling operation of the label 32 to the cup lid, it is not necessary to control the robot arm to stop and spray adhesive on the label 32, thereby shortening the time required for labeling the cup lid and improving work efficiency.

[0047] Example 3

[0048] like Figures 1-6 As shown, based on the above embodiments, this embodiment further provides the following:

[0049] In this embodiment, the connecting mechanism 5 includes a horizontally oriented connecting column 51 fixedly mounted on the sliding block 41.

By setting the scale 512, when the threaded rod 3 53 is rotated to make the connecting shell 52 move outside the connecting post 51, the end of the connecting shell 52 and the scale 512 change. Thus, according to the scale 512, the distance that the worker moves through the connecting shell 52 outside the connecting post 51 corresponds to the distance that the worker moves through the connecting shell 52, which makes it convenient for the worker to adjust the position of the roller 611 according to the thickness of the sign 32.

[0051] In the embodiment, the fixed block 6 is fixedly installed with a mounting column 8 on the side away from the mounting block 3, the bottom of the mounting column 8 extends to the lower side of the roller 611 and is fixedly installed with an open-top collecting box 81 directly below the roller 611, the bottom of the collecting box 81 is fixedly installed with a discharging valve in communication with the inside of the collecting box 81, through the arrangement of the collecting box 81, when the glue in the roller 611 flows to the sponge sleeve 615 and the glue on the sponge sleeve 615 seeps outwards, the glue drips down the sponge sleeve 615 and falls into the collecting box 81, achieving the effect of collecting the glue seeping outwards on the sponge sleeve 615, through the design of the discharging valve, the glue collected in the collecting box 81 can be conveniently treated.

[0052] In the embodiment, the two ends of the guide rail 4 extending to the outside of the mounting block 3 are inclined in the direction of the connecting plate 2, through the arrangement of the two ends of the guide rail 4 extending to the outside of the mounting block 3 being inclined in the direction of the connecting plate 2, when the sliding block 41 slides along the guide rail 4 to the end of the guide rail 4 through the driving mechanism 7, the roller 611 rotates around the end of the housing 72 and approaches the mounting block 3, so that the roller 611 is located at the outside of the negative pressure suction disc 31, achieving the effect of giving way.
