Description

Technical Field

[0002] In the existing solid-state hard disk dynamic labeling process, according to the process requirements, some memory sticks need to be labeled on the front and some memory sticks need to be labeled on the back, while the existing automatic labeling production line can only cope with one labeling process and has low adaptability.

[0003] Furthermore, due to the extremely limited space in the production line, it is difficult to design a production line that can label both sides of the memory sticks.

[0004] Therefore, there is an urgent need for a labeling production line with wide applicability and small size that can solve the above problems. Summary of the invention

[0005] The object of the present invention is to provide a loading and conveying device and an automatic labeling production line. When labeling a memory stick, the loading and conveying device can choose whether to flip the memory stick 180 degrees according to the labeling requirements. It has wide applicability, and when flipping is not needed, the flip loading table can be rotated and folded, occupying a small volume.

[0006] In order to achieve the above-mentioned purpose, the present invention discloses a loading and conveying device, including a material transmission mechanism, a flip loading platform and a fixed loading platform, wherein the fixed loading platform is provided with a first material clamp which can be moved to a first position or is located at the first position, the flip loading platform includes a rotating frame rotatably mounted on a frame along a vertically arranged first rotating axis, a sliding frame slidably mounted on the rotating frame along a vertical direction, a second material clamp rotatably mounted on the sliding frame along a horizontally arranged second rotating axis, a flip driving part driving the second material clamp to rotate along the second rotating axis, and a lifting driving part driving the sliding frame to rise and fall along the rotating frame, the rotating frame drives the second material clamp to rotate between a first position and a second position, and the second material clamp is suspended on the sliding frame and can be lifted and lowered between a first horizontal height where the first material clamp is located and a second horizontal height higher than the first horizontal height under the drive of the lifting driving part, the flip driving part can drive the second material clamp to flip 180 degrees at the second horizontal height, and its flipping area is higher than the first horizontal height, and the material transmission mechanism grabs the material and moves the material from a material taking platform to the first position.

[0007] Compared with the prior art, the present invention can choose whether to flip the memory stick 180 degrees when labeling the memory stick according to the labeling requirements, and has wide applicability. If flipping is required, the flip loading platform is rotated to the first position, and the positioning surface of the second material clamp is set upward. The material transmission mechanism can move the material from a material picking platform to the second material clamp, and the flip driving part can drive the second material clamp to flip 180 degrees and drop to the first horizontal height to place the material on the first material clamp. When flipping is not required, the flip loading platform is rotated to the second position, and the material transmission mechanism directly moves the material from a material picking platform to the second material clamp, that is, the flip loading platform can be rotated and folded when idle, occupying a small volume and convenient to fold.

[0008] Preferably, the fixed loading platform further comprises a moving mechanism, and the moving mechanism drives the first material clamp to move between the first position and the third position. This solution makes the first position and the second position a transfer position.

[0009] Preferably, the second material clamp and the first material clamp both include a clamp body and a limiting groove formed on the bottom surface of the clamp body, and a vacuum hole connected to a vacuum pipe is formed at the bottom of the limiting groove, and the material can be installed in the limiting groove and adsorbed on the bottom of the limiting groove.

[0010] Preferably, the rotating frame is provided with an air-avoiding positioning groove for the vacuum tube to pass through.

[0011] Preferably, the flip driving unit can drive the second material clamp to flip 180 degrees at the second horizontal height, and its flipping area is higher than the first horizontal height.

[0012] Preferably, the material transmission mechanism includes a nozzle robot, the nozzle robot sucks electronic products and moves between the third position and the loading station through a three-dimensional manipulator; the nozzle robot includes a grabbing frame, a first nozzle driving unit installed on the grabbing frame, a first grabbing group, and a second grabbing group, the first grabbing group is slidably installed on the grabbing frame along the X direction and can move relative to the second grabbing group, the first nozzle driving unit drives the first grabbing group to move on the grabbing frame relative to the second grabbing group, the first grabbing group and the second grabbing group are provided with one or more suction cups for sucking electronic products, and when the first grabbing group or the second grabbing group has multiple suction cups, the multiple suction cups are arranged along the Y direction perpendicular to the X direction, and the suction cups are arranged toward the Z direction, and the X direction, Y direction, and Z direction are perpendicular to each other. This solution enables the nozzle robot to adjust the distance between the first grabbing group and the second grabbing group according to the placement size of the material on the loading platform and the material fixture, further increasing the applicability of material transportation and high transportation efficiency.

[0013] Specifically, the nozzle robot further includes a second nozzle driving unit, the second grabbing group is slidably mounted on the grabbing frame in a direction parallel to the first grabbing group, and the second nozzle driving unit drives the second grabbing group to slide along the grabbing frame. This solution enables the nozzle robot to adjust the positions of the first grabbing group and the second grabbing group respectively, so that the conveying center line of the nozzle robot remains unchanged and is easy to control.

[0014] More specifically, the first gripping group and the second gripping group each include a sliding rail, three fixed blocks slidably mounted on the sliding rail at a certain interval, a rotating shaft arranged along the sliding rail, and a rotating driving part driving the rotating shaft to rotate. A suction cup is arranged on each fixed block, a slider is arranged on the fixed block, and three slide grooves corresponding to the fixed block and for the slider to slide are arranged on the rotating shaft. The slide groove corresponding to the middle fixed block is a groove circumferentially around the rotating shaft, and the slide grooves corresponding to the two fixed blocks on both sides are spiral grooves around the rotating shaft, and the spiral directions of the spiral grooves are opposite. This solution enables the nozzle robot to adjust the relative positions of the suction cups in each group.

[0015] The present invention also discloses an automatic labeling production line, comprising a production transmission line, a material clamp arranged on the production transmission line and carrying materials, a loading station and a labeling station arranged in sequence along the conveying direction of the production transmission line, a loading and conveying device arranged at a position corresponding to the loading station, and a labeling machine arranged at a position corresponding to the labeling station, the loading and conveying device is as described above and is adjacent to the loading station, the material conveying mechanism also moves the material from the first material clamp to the loading station, the labeling machine comprises a label printer, a label conveying device and a label grabbing mechanism, the label printer prints labels, the label conveying device and the label grabbing mechanism grab the printed labels and convey them to the materials at the labeling station to complete labeling.

[0016] Preferably, the labeling machine includes a label printer, a label conveying device and a label grabbing mechanism. The label conveying device includes a driving mechanism and a conveyor belt. The driving mechanism includes a driving unit and a plurality of driving rollers. The conveyor belt is formed by a plurality of transmission line bodies arranged side by side at a certain interval. Each of the transmission line bodies bypasses the driving roller and is connected end to end. A through groove is formed between adjacent transmission line bodies. The driving unit drives the driving roller to rotate, and a plurality of driving rollers drive the transmission line bodies to rotate synchronously. One end of the conveyor belt is connected to the label printer and conveys the label. The label grabbing mechanism grabs the label from the end of the conveyor belt and conveys the label to the labeling station through a three-dimensional manipulator. In this solution, the labeling machine uses a conveyor belt to convey labels, which effectively shortens the distance that the three-dimensional manipulator conveys the label. It is small in size and high in efficiency. Using a transmission line body to convey labels reduces the stickiness between the label and the conveyor belt, and prevents the label from sticking to the conveyor belt and being unable to be removed.

[0017] Specifically, the drive roller is provided with a plurality of annular receiving grooves corresponding to the transmission line body along its axial direction, and the transmission line body is installed in the annular receiving grooves. This solution increases the friction between the transmission line body and the drive roller to prevent slipping. Of course, the friction between the transmission line body and the drive roller can be increased by increasing the friction coefficient between the drive roller (the surface of the annular receiving groove) and the transmission line body (for example, by means of materials, coatings, patterns, etc.).

[0018] More specifically, the transmission line body is a round wire or a flat wire. The round wire can reduce the stickiness between the transmission line body and the back of the label. When the label is carried on the transmission line body with the front side facing up, the round wire can reduce the contact area between the back of the label with the adhesive layer and the transmission line body, making it easier to peel off the label when taking the material. The cross section of the round wire can be circular, elliptical or special-shaped arc (such as gourd shape).

[0019] Preferably, the top of the protrusion is flat.

[0020] Preferably, the top of the protrusion is arc-shaped, which further reduces the adhesion between the label and the conveyor belt.

[0021] Preferably, the conveyor belt is made of polytetrafluoroethylene to prevent the label from being too tightly attached to the conveyor belt, thereby facilitating separation of the label from the conveyor belt.

[0022] More preferably, the labeling machine further comprises a material taking station arranged at the end of the conveyor belt and a lifting top plate installed at the material taking station, the lifting top plate is provided with a plurality of top blocks corresponding to the positions of the through grooves and capable of passing through the through grooves from bottom to top, the lifting top plate can be lifted and lowered under the drive of a lifting drive unit so that the top blocks pass through the through grooves and lift up the labels on the conveyor belt. The lifting top plate enables the lifting top plate to be lifted upward and the labels to be lifted from the conveyor belt when taking materials, so that the labels and the conveyor belt are separated, and the conveyor belt can continue to run at this time, further improving the conveying efficiency of the labels.

[0023] Specifically, at least one vacuum hole connected to the vacuum pipe is formed on the upper surface of each of the top blocks, and the top block pushes the label and can absorb the label through the vacuum hole. When the lifting top plate pushes the label upward, the label is absorbed while pushing, so as to prevent the label from being pushed up during the operation of the conveyor belt, so that the label bounces off the lifting top plate.

[0024] Specifically, a detector for detecting labels is provided at a position corresponding to the material taking station, and the detector detects whether the material taking station has a label.

[0025] Specifically, the label conveying device also includes a belt pressing plate, which is located above the conveyor belt and at a position corresponding to the material picking station and has a certain gap with the upper surface of the conveyor belt. A slot hole is provided on the belt pressing plate for the top block to pass through. The belt pressing plate prevents the conveyor belt from being pulled when the top block label is detached from the conveyor belt.

[0026] Specifically, the label conveying device further comprises a support plate, which is arranged in the conveyor belt and supports the body of the conveyor belt, and a clearance groove is provided at a position of the support plate corresponding to the material taking station.

The loading station 401 and the dividing station 402 are arranged side by side. In this scheme, the mobile frame 412 slides in the horizontal direction relative to the mounting frame 411. Of course, there can also be a certain height difference or a certain angle between the loading station 401 and the dividing station 402.
