[0002] In the semiconductor industry, wafer cassettes serve as crucial containers for carrying wafers, and their labeling process is of paramount importance. Wafer cassettes come in various shapes, including round and square, and during production, labels must be affixed to their surfaces to identify relevant information such as specifications, applicable wafer size, production date, batch number, and unique identifier. This facilitates production management, quality traceability, and logistics tracking.
[0003] Traditional small businesses typically use manual labeling, which is inefficient and cannot meet the needs of large-scale production. At the same time, it is difficult to guarantee accuracy and consistency, and problems such as missing labels, incorrect labels, and inconsistent label positions are prone to occur.
[0004] Large enterprises mostly use robotic arms to automate labeling. Automated labeling is a significant improvement over manual labeling and can increase labeling efficiency. However, automated labeling equipment is expensive, and for some small and medium-sized enterprises, the investment and maintenance costs are high. In addition, the debugging and operation of the equipment require professional technicians, which also limits its widespread application to some extent. Utility Model Content

Detailed Implementation
[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figure 1-9 The labeling device for a plastic tank in this embodiment includes a middle frame 1, on which a double belt conveyor 2 is installed for conveying boxes; at least three sets of limiting components are installed on the inner side of the middle frame 1 for limiting the boxes; a stacking component is installed on the right side of the middle frame 1, and a transfer component is installed on the top. The cooperation between the transfer component and the stacking component is used to stack the labeled boxes.
[0026] like Figure 7-9The transfer assembly includes two sets of mounting plates 26 fixed on the central frame 1 at the middle section of the double belt conveyor 2. Linear modules 27 are mounted on each mounting plate 26. The moving ends of the linear modules 27 are respectively fixed with a first moving plate 28 and a second moving plate 29 that slide against the corresponding mounting plate 26. The linear modules 27 can drive the first moving plate 28 and the second moving plate 29 to move. A downward-pushing cylinder 30 is mounted on both the first moving plate 28 and the second moving plate 29. The pushing end of the downward-pushing cylinder 30 on the first moving plate 28 is fixed with a convex plate 32, and the downward-pushing cylinder on the second moving plate 29... The push end of the 30 is fixed with a circular plate 31. Both the circular plate 31 and the convex plate 32 are equipped with multiple suction cup devices 33. The convex plate 32 has five suction cup devices 33, four on the left and one on the right. The four suction cup devices on the left are used to adsorb and stick the label to the box body, and the one on the right side is used to balance the box body and prevent one end from tilting up when pressing the label to improve stability. The circular plate 31 has six suction cup devices 33 distributed in a circle to fit the box body. The lower top cylinder 30 can drive the circular plate 31 and the convex plate 32 to move up and down, thereby driving the suction cup devices 33 to move up and down, thus completing the label picking, labeling and unloading process.
[0027] To further explain, a slotted photoelectric sensor 36 is installed on the top of the circular plate 31, and a sleeve post 34 is inserted through the center to limit the movement. A pressure block 35 is fixed at the bottom of the sleeve post 34, and a trigger plate 37 that can trigger the slotted photoelectric sensor 36 is fixed at the top. When the pressure block 35 contacts the plastic slot, the sleeve post 34 rises, and the trigger plate 37 enters the slotted photoelectric sensor 36, triggering the sensor to send a signal, which facilitates the control of the corresponding lower cylinder to retract. This allows the suction cup device to adhere to the box in the optimal position for adsorption, thereby avoiding the occurrence of falling due to insufficient suction during the adsorption process.
[0028] Among them, such as Figure 6 A left platform 3 is fixed on the left side of the middle frame 1, and a support platform 23 is fixed on the left platform 3. A side-push cylinder 24 is installed on the top of the support platform 23. A suction block 25 for receiving external labels is fixed to the piston rod of the side-push cylinder 24. Multiple small protrusions are formed on the suction block 25. The suction block 25 can absorb the label. The side-push cylinder 24 can push the suction block 25 to receive the label sent from the outside. Then, the label is absorbed and transferred to the box body for pasting by the adsorption device on the convex plate 32. The small protrusions can reduce the contact area with the label, making it easier to absorb and remove the label.
[0029] like Figure 5The limiting assembly includes three inner plates 12 fixed on the middle frame 1 and located inside the double belt conveyor 2. An upper cylinder 13 is fixed to the bottom of the inner plate 12. The piston rod of the upper cylinder 13 is fixed to a concave upper plate 14. A stop post 15 is fixed to the top of the protruding end of the upper plate 14. The upper cylinder 13 can drive the upper plate 14 to move up and down, thereby driving the stop post 15 to move up and down. When the box is being conveyed, the stop post rises in advance. When the stop post can move the box to the designated position, a pre-waiting area, a bonding area, and a feeding area are formed.
[0030] like Figure 4 A support plate 16 is fixed on the inner side of the middle section of the middle frame 1, between the two sets of limiting components on the left. Two sets of guide posts 18 are fixed on the top of the support plate 16, and a push cylinder 17 is fixed between the guide posts 18. The piston rod of the push cylinder 17 is fixed with a push plate 19 that slides with the guide posts 18. The push cylinder 17 can drive the push plate 19 to move along the guide posts 18. A platform 20 is fixed on the top of the push plate 19. A rotary motor 21 is installed at the bottom of the platform 20. A turntable 22 is fixed on the shaft end of the rotary motor 21. The turntable 22 and the suction block 25 are located on the same axis. The operation of the push cylinder drives the turntable to lift through the push plate, thereby lifting the box in the bonding area and separating it from the double belt conveyor. The turntable 22 is rotated by the rotary motor 21 as needed to adjust the angle of the box for labeling, thereby ensuring consistent labeling position and labeling stability.
[0031] like Figure 3 The stacking assembly includes a right platform 4 fixed to the right side of the central frame 1. Two sets of columns 5 are mounted on the right platform 4. A base plate 6 is fixed between the bottoms of the columns 5, and a top plate 8 is fixed between the tops of the columns 5. A screw nut 7 is rotatably installed between the top plate 8 and the base plate 6. A belt drive device 9 is also installed on the right platform 4. One of the pulleys of the belt drive device 9 is fixed to the nut of the screw nut 7. The belt drive device 9 can drive the screw nut 7 to rotate, thereby driving the top plate 8 to move up and down to realize the stacking of the boxes.
[0032] To further explain, a support platform 10 is fixed to the top of the right platform 4. An opening adapted to the top plate 8 is provided on the platform surface of the support platform 10. Six columns 11 are fixed to the top of the support platform 10 around the opening. The columns 11 can limit the stacked boxes and prevent them from tipping over.
[0033] The working principle of the above embodiments is as follows:
[0034] After the equipment starts, the boxes are conveyed on the central frame by a double belt conveyor. During the conveying process, the upper cylinder drives the upper plate to move up and down, which in turn raises and lowers the baffles. The baffles rise in advance, blocking the boxes in sequence at designated positions, forming a pre-waiting area, a bonding area, and a unloading area, thus achieving orderly stopping of the boxes. In the labeling preparation stage, the side-push cylinder on the top of the support platform on the left platform pushes the suction block to move, receiving the labels sent from the outside. Multiple small protrusions on the suction block reduce the contact area with the labels, making it easier to pick up the labels later. The push cylinder on the inner side of the middle section of the central frame is activated. The push plate drives the platform to rise along the guide column, causing the turntable to lift the box and separate it from the double belt conveyor. According to the labeling requirements, the rotary motor drives the turntable to rotate, adjusting the box to the appropriate angle to ensure accurate labeling. Then, the linear module on the mounting plate drives the first moving plate to move. When it moves above the suction block, the lowering cylinder on the first moving plate pushes the convex plate downwards. The suction cup device on the convex plate picks up the label on the suction block, and the suction block stops running. Afterwards, the linear module drives the first moving plate to move above the box in the bonding area, and the lower... The top cylinder pushes the convex plate down again, affixing the label to the box. At this time, a suction cup device on the right side of the convex plate balances the box, preventing one end of the box from tilting up when the label is applied, ensuring labeling stability. After labeling, the box is conveyed to the unloading area. The linear module drives the second moving plate to move above the box in the unloading area. The bottom cylinder pushes the circular plate down. When the pressure block at the bottom of the circular plate contacts the box, the sleeve rises, causing the trigger plate to enter the slotted photoelectric sensor. The sensor sends a signal to control the bottom cylinder to stop descending. At this time, the circular plate... The six suction cups arranged in a circle fit perfectly against the box and attach to it. Then, the linear module moves the second moving plate to the top of the stacking assembly's support platform. The bottom cylinder lowers the circular plate, and the suction cups release the box, placing it at the opening of the support platform. During the stacking process, the belt drive on the right platform drives the lead screw nut to rotate, causing the top plate to move up and down along the columns. This, in conjunction with the suction cups, completes the layer-by-layer stacking of the boxes. The six columns on the top of the support platform are distributed around the opening, which limits the stacked boxes and prevents them from tipping over.
[0035] Through the coordinated operation of its various components, the equipment achieves an automated workflow for conveying, limiting, labeling, and stacking boxes.
[0036] The entire workflow is now complete, and anything not described in detail in this specification is existing technology known to those skilled in the art.
