Description

Technical Field

[0001] The utility model belongs to the field of optical glass production, and specifically relates to an optical glass strip weighing, labeling and stacking device, which is used for automatic weighing, labeling and stacking operations after continuous long strips of optical glass blanks are divided into finished optical glass strips. Background Art

[0002] During the optical glass production process, batch materials undergo melting, forming, and annealing to produce continuous, long billets. These billets are then pulled out of the annealing furnace's mesh belt and split into finished optical glass strips. These are then stacked and palletized, and then sent in batches for subsequent inspection and packaging. To meet lean production requirements such as furnace output statistics, production process traceability, and on-site material mixing prevention, the strips are weighed and labeled after they are split and before they are palletized. Data such as the glass brand, furnace number, production date, and weight are integrated into a barcode. The corresponding characters and barcode are printed onto labels and affixed to the surface of the glass strips, allowing subsequent processes to retrieve product information by scanning the barcode. Furthermore, to facilitate online quality monitoring, on-site sampling of the strips is performed at specific intervals during the production process. These samples, such as bubble samples for bubble indicator monitoring and streak samples for streak indicator monitoring, are removed from the palletizing process before palletizing. On-site inspectors remove these samples from the sample storage area and submit them for inspection on a timely basis. In the traditional production process, the splitting and cutting of optical glass strips is done manually. After the operator completes the splitting and cutting of the strips online, they then carry out tasks such as weighing, labeling, sampling, and stacking as required. With the promotion of production process automation, the splitting and cutting of optical glass strips has gradually been automatically completed by dedicated mechanical equipment. Therefore, there is an urgent need for a supporting device to replace the manual weighing, labeling, sampling, and stacking tasks after the strips are split. The invention patent with application number CN202410083417 discloses a glass stacking device that can realize the automatic glass stacking process, but it does not have functions such as automatic weighing, labeling, and sampling, and cannot fully meet the lean production needs of optical glass strips.

DETAILED DESCRIPTION

[0018] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0019] In the embodiments, methods, principles and circuits well known to those skilled in the art, such as serial communication technology and robotic arm palletizing control, are not described in detail in order to highlight the main purpose of the present invention.

[0020] like Figure 1 As shown, an embodiment of the optical glass strip weighing, labeling and palletizing device provided by the present invention includes a frame 1, a positioning unit, a weighing unit, a labeling unit, a palletizing unit and a control unit.

[0021] The positioning unit consists of a feed table 6, unpowered rollers 7, and a clamping member 2. A predetermined number of unpowered rollers 7 are evenly distributed in grooves at one end of the feed table 6, with the upper edges of their cylindrical surfaces flush with the upper surface of the feed table 6. The clamping member 2 comprises a clamping cylinder, a workpiece clamping plate, and a rodless cylinder. The rodless cylinder is mounted on the feed table 6, the clamping cylinder is mounted on a slide formed by the rodless cylinders, and the workpiece clamping plate is mounted on connecting rods on either side of the clamping cylinder. Under the control of the control unit, the clamping member 2 can grip the workpiece 6 and slide along the surfaces of the feed table 6 and unpowered rollers 7.

[0022] The weighing unit includes an electronic scale 3, a lifting cylinder 4, and a top plate 5. The lifting cylinder 4 is vertically mounted on the frame 1. The electronic scale 3 is mounted on the output shaft of the lifting cylinder 4 via a horizontal support plate. There are generally three top plates 5, which are vertically mounted on the weighing plate of the electronic scale 3. The vertical surface of the top plate 5 is parallel to the axis of the unpowered roller 7 and is located in the middle of the gap between the unpowered rollers 7.

[0023] The labeling unit includes a label printer 9, a labeling cylinder 13, and a label suction cup 12. The label printer 9 is mounted on the side of the frame 1, the labeling cylinder 13 is mounted on the label printer 9, and the label suction cup 12 is mounted on the output shaft of the labeling cylinder 13 and located near the label outlet of the label printer 9. After the label 11 printed with characters and barcodes is sent out from the label outlet by the label paper feed drive wheel assembly 10 inside the label printer 9, it can be sensed by the sensor installed in the label suction cup 12 and adsorbed on the surface of the label suction cup 12.

[0024] like Figure 1 and Figure 2As shown, the palletizing unit includes a robotic arm 14, a workpiece suction cup 15, a sample tray 8, and a finished product tray (not shown). The robotic arm 14 and finished product tray are fixed around the frame 1 at specific coordinates, with their relative positions ensuring the normal arm span of the robotic arm 14. The workpiece suction cup 15 is mounted on the rotating shaft at the end of the robotic arm 14. The sample tray 8 is mounted on one side of the frame, above the labeling unit. The sample tray 8 has a notch perpendicular to the label suction cup 12. During labeling, the labeling cylinder 13 drives the label suction cup 12 to extend from below the notch of the sample tray 8. The sample tray 8 is sequentially provided with areas for placing bubble samples 801, stripe samples 802, and abnormal items 803. In some embodiments, the sample tray 8 is also equipped with a barcode scanner 804.

[0025] In some embodiments, the palletizing unit further comprises Figure 3 The partition feeder shown is composed of a bracket 16, a stepper motor 17, a ball screw 18, a slide 19, a connecting rod 20, a partition support 21, a handwheel 22, a bidirectional screw 23, a telescopic plate 24, etc. The stepper motor 17 and the ball screw 18 are installed on the bracket 16, the slide 19 is connected to the ball screw 18, the partition support 21 is connected to the slide 19 through the connecting rod 20, the handwheel 22 is connected to one end of the bidirectional screw 23, and two telescopic plates 24 are installed on the bidirectional screw 23 and on both sides of the partition support 21. A photoelectric sensor 25 is installed on the top of one of the telescopic plates.

[0026] Combined with Figures 1 to Figure 3 , the specific implementation of the embodiment of the utility model is as follows:

[0027] After the optical glass strip is cut and broken, it is pushed to a fixed position on the feed table. When the control unit receives a signal indicating the workpiece is in place, the positioning unit activates. The clamping cylinder in clamping element 2 drives the workpiece clamping plates to clamp the strip from both sides. A slide composed of rodless cylinders slides the workpiece along the surface of the feed table 6 and unpowered roller 7 until it is above the top plate 5. At this point, the weighing unit activates, and lifting cylinder 4 actuates, driving electronic scale 3 upward. Top plate 5, mounted on the weighing plate of electronic scale 3, extends from under unpowered roller 7, lifting the strip and maintaining this position for several seconds. After this, lifting cylinder 4 lowers electronic scale 3 and top plate 5 to their initial positions. Electronic scale 3 transmits the weight data to the control unit via a serial communication line. The control unit then responds with different control outputs based on whether the weighing signal is normal or not. When the control unit receives a signal indicating a normal weighing, the labeling unit begins to print a label 11 corresponding to the current time, glass brand, and weighed weight. Label 11, printed with characters and a barcode, is ejected from the label outlet and attached to the label suction cup 12 for later use. Simultaneously, the palletizing unit begins to operate. Robot arm 14 drives workpiece suction cup 15 to pick up the strip from unpowered roller 7, transfer the strip, and position it above label suction cup 12 at the corner of sample tray 8. This position signal is then sent to the control unit. When the control unit receives a signal indicating a workpiece has reached the labeling position, it controls the labeling cylinder 13 to momentarily lift label suction cup 12, applying label 11 to the lower surface of the strip. If the control unit does not receive a normal weighing signal after a set delay, it instructs robot arm 14 to place the strip as an abnormal item 803 onto sample tray 8, completing the single palletizing process.

[0028] In the above process, for the strip workpiece that has completed normal weighing and labeling, the robot arm 14 and the workpiece suction cup 15 continue to transfer it to the top of the barcode scanner 804 installed in the sample stacker 8. The barcode scanner 804 transmits the scanned code information to the control unit and compares it with the label print content. If the scanned code verification is correct, it enters the subsequent stacking process. Otherwise, the strip workpiece will be placed on the sample stacker 8 as an abnormal part 803, and the single stacking process ends.

[0029] After the workpiece enters the palletizing process, the control unit determines whether the strip workpiece belongs to the sample that should be extracted, such as a bubble sample for detecting the bubble index inside the glass or a stripe sample for detecting the stripe index inside the glass, based on the pre-set sampling cycle. If it coincides with the bubble sampling cycle, the corresponding workpiece is placed on the sample pallet 8 by the robotic arm 14 as a bubble sample 801; if it coincides with the stripe sampling cycle, it is placed on the sample pallet 8 as a stripe sample 802; if it does not belong to a sample, the strip is placed on the finished product pallet for stacking and stacking according to the conventional palletizing procedure set inside the robotic arm.

[0030] In some embodiments, when glass strips are placed on the finished pallet for stacking, a paper partition with a thickness of 2-3 mm and similar to the length and width of the strips and similar to the thickness of the strips is placed between the upper and lower stacked strips to avoid collision damage. The partitions are stacked in batches on the partition support 21 of the partition feeder, between two telescopic plates 24. The handwheel 22 drives the bidirectional screw 23 to rotate, and the distance between the telescopic plates 24 is adjusted to adapt to the width of the partitions. After the partition feed is started, the stepper motor 17 drives the partition support 21 to rise through the ball screw 18, slide 19 and connecting rod 20 until the surface of the upper partition reaches the sensing area of ​​the photoelectric sensor 25. During operation, after the robot arm 14 places the strips on the finished pallet, it runs to the top of the partitions stacked in the partition feeder. The workpiece suction cup 15 picks up a partition, and after the height is corrected according to the previous stacking coordinates, the partition is placed on the upper surface of the previous strip workpiece on the finished pallet, and the single stacking process is completed.

[0031] After a single palletizing process is completed, the robot arm 14 returns to its initial position and waits for the next process to begin.

[0032] During the operation of the embodiment, when anomalies occur in weighing, labeling, code scanning, partition feeding, etc., the control unit issues an abnormality alarm and notifies on-site personnel to deal with it in time; when bubble samples 801, streak samples 802 or abnormal parts 803 are placed on the sample tray 8, the control unit issues a prompt alarm and notifies on-site personnel to extract them in time.

[0033] The embodiment of the utility model can complete the automatic weighing, labeling, code scanning verification, sampling, and stacking of optical glass strips during the production process, meeting the lean production needs of optical glass strips in terms of furnace output statistics, production process traceability, and on-site material mixing prevention.
