Description

Technical Field

[0001] This utility model relates to the field of visual labeling machine technology, specifically to a fully automatic visual labeling machine. Background Technology

[0002] In today's diversified and fiercely competitive market environment, the standardization and accuracy of product labeling play a crucial role in product circulation, sales, and brand image building. Among these methods, affixing labels to both sides of the product is a common and widely demanded labeling method.

[0003] Currently, most double-sided labeling machines on the market are designed for products without adhesive layers. For these products, double-sided labeling requires the machine to precisely affix two labels with adhesive layers to the front and back of the product. However, more and more products with built-in adhesive layers are emerging in the market, and the labeling process for these differs significantly from that of products without adhesive layers. During the production process, products with built-in adhesive layers typically have a release liner covering their surface to protect the adhesive layer from contamination or accidental adhesion during storage and transportation. Before labeling, this release liner must be peeled off to expose a clean, intact adhesive layer on the product surface, and then the label without adhesive layer can be accurately affixed to that position. Existing double-sided labeling machines, because they were not designed with this special labeling requirement for products with built-in adhesive layers in mind, struggle to meet the requirements of release liner peeling and subsequent precise labeling, and therefore, most cannot be directly applied to labeling these products.

[0004] Currently, labeling products with self-adhesive layers mainly relies on manual labor or semi-automatic labeling machines. The process requires significant human intervention, such as in the peeling of the release liner, making fully automated production impossible. Manual labeling is inefficient and, in large-scale production environments, struggles to meet the high-speed, continuous production pace, leading to extended production cycles and impacting product delivery times. Furthermore, prolonged, high-intensity labeling work causes operator fatigue, increasing labor intensity and negatively impacting their health. Fatigue can also lead to errors, compromising the accuracy of manual labeling.

[0005] Therefore, in order to meet the double-sided labeling requirements of products with self-adhesive layers, improve production efficiency, ensure labeling accuracy, and reduce production costs, it is necessary to develop a fully automatic vision labeling machine. Utility Model Content

[0006] (a) Technical problems to be solved This invention provides a fully automatic visual labeling machine, which can at least solve the technical problem of how to improve the production efficiency and labeling accuracy of products with self-adhesive layers.

The first label feeding device and the second label feeding device are both mounted on the frame. The first label feeding device is located on one side of the first visual labeling device, and the second label feeding device is located on one side of the second visual labeling device. The product feeding device is used to transfer products one by one to the conveyor line.

The flip plate drive mechanism is mounted on the frame and is connected to the flip plate for transmission. The flip plate drive mechanism is used to drive the flip plate to rotate around its own rotation axis so that each limiting groove alternately docks with the conveyor line to dock the limiting groove for product input or output.

[0010] Furthermore, both the aforementioned first visual labeling device and second visual labeling device include: The first and second inspection mechanisms are both located on the frame. The first inspection mechanism is located above the conveyor line and is used to inspect the position of the product adhesive layer on the conveyor line. The second inspection mechanism is located on one side of the conveyor line and is used to inspect the position of the label. The bonding mechanism, located on the frame, is used to grab the front label or the back label of the product and transfer it to the second testing mechanism for testing. Then, based on the testing results of the first and second testing mechanisms, the front label or the back label of the product is aligned and pressed onto the adhesive layer on the front or back of the product.

[0011] Furthermore, the aforementioned first inspection mechanism is also used to inspect the quality of product labeling on the conveyor line. Both the first visual labeling device and the second visual labeling device also include a third inspection mechanism. The third inspection mechanism is located on the frame, above the conveyor line, upstream of the first inspection mechanism, and is used to inspect whether there are any defects in the appearance of the products on the conveyor line. The fully automatic vision labeling machine also includes a defective product unloading device, which is mounted on the frame and located on one side of the conveyor line. The defective product unloading device is used to remove unqualified products from the conveyor line based on the detection results of the first and third detection mechanisms.

[0012] Furthermore, the aforementioned fully automatic visual labeling machine also includes two roller pressing devices, both of which are mounted on the frame and located downstream of the first and second visual labeling devices, respectively. The two roller pressing devices are used to press the front and back of the product, respectively.

[0013] Further configuration: the aforementioned roller pressing device includes a lifting mechanism, a bidirectional displacement mechanism, and two pressure rollers. The lifting mechanism is mounted on the frame, and the bidirectional displacement mechanism is mounted on the output end of the lifting mechanism. The output end of the bidirectional displacement mechanism is rotatably connected to the two pressure rollers. The lifting mechanism is used to drive the two pressure rollers to move toward or away from the product on the conveyor line, while the bidirectional displacement mechanism is used to drive the two pressure rollers to move toward or away from each other.

[0014] Further configuration: the aforementioned conveyor line includes a conveyor belt and at least two limiting plates. Both the conveyor belt and the limiting plates are mounted on the frame.

The device includes a material carrier plate, a pneumatic component, a connecting rod, and a first lifting mechanism. Two material carrier plates are provided, each sliding vertically within a storage trough. The first lifting mechanism is mounted on a storage rack. The connecting rod slides between the two material carrier plates. The pneumatic component is located at the output end of the first lifting mechanism and is connected to the connecting rod via a transmission mechanism. The pneumatic component drives the connecting rod to slide away from one of the material carrier plates and engage with the other. The first lifting mechanism drives the lifting motion of the material carrier plate engaged with the connecting rod, and the material carrier plates drive the lifting motion of the products within the corresponding storage troughs. The machine includes a rotating mechanism, a second lifting mechanism, and two adsorption fixtures. The rotating mechanism is mounted on the frame, and the second lifting mechanism is located at the output end of the rotating mechanism. The output end of the second lifting mechanism is connected to the two adsorption fixtures. The adsorption fixtures are used to adsorb or release products. The rotating mechanism is used to drive the adsorption fixtures to alternately face the conveyor line and the storage tank connected to it.

[0017] (III) Beneficial Effects Compared with the prior art, the fully automatic visual labeling machine provided by this utility model has the following beneficial effects: When using the fully automatic visual labeling machine provided by this utility model, firstly, the product feeding device transfers the products to be labeled one by one to the conveyor line, with the front of the product facing up. At the same time, the first label feeding device and the second label feeding device place the front label and the back label of the product in designated positions, respectively. Then, the conveyor line transports the product to the first film-peeling device, which peels off the release paper on the front of the product to expose the adhesive layer. Next, the conveyor line transports the product to the first visual labeling device, which picks up the front label and affixes it to the adhesive layer on the front of the product, completing the front labeling. Subsequently, the conveyor line transports the product to the flipping device, which flips the product so that the back side faces up. Then, the conveyor line transports the product sequentially to the second film-peeling device and the second visual labeling device, which repeat the above operation to affix the back label to the adhesive layer on the back of the product, completing the back labeling. Finally, the unloading device transfers the finished product out of the conveyor line. As can be seen, this utility model achieves fully automated production of double-sided labeling of products with self-adhesive layers through the coordinated operation of various devices, which greatly improves production efficiency, reduces manual intervention, reduces labor intensity, and at the same time ensures labeling accuracy and product quality.

[0020] 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.

[0021] This utility model provides a fully automatic visual labeling machine to solve the problem of how to improve the production efficiency and labeling accuracy of products 12 with self-adhesive layers.

[0022] See Figure 1 As shown, Figure 1 The above view shows the fully automatic visual labeling machine in the embodiment. The fully automatic visual labeling machine includes a frame 1, a conveyor line 2, a product feeding device 3, a first film tearing device 4, a first visual labeling device 5, a flipping device 6, a second film tearing device 7, a second visual labeling device 8, a feeding device 9, a first label feeding device 10, and a second label feeding device 11.

[0023] Conveyor line 2 is installed on frame 1 and is used to transport product 12.

[0024] The product feeding device 3, the first film-tearing device 4, the first visual labeling device 5, the flipping device 6, the second film-tearing device 7, the second visual labeling device 8, and the unloading device 9 are all installed on the frame 1 and arranged sequentially along the conveying direction of the conveyor line 2.

[0025] The first label feeding device 10 and the second label feeding device 11 are both mounted on the frame 1. The first label feeding device 10 is located on one side of the first visual labeling device 5. The second label feeding device 11 is located on one side of the second visual labeling device 8.

[0026] The product loading device 3 is used to transfer products 12 one by one onto the conveyor line 2. The first film-peeling device 4 and the second film-peeling device 7 are used to peel the release paper from the front and back of the product 12, respectively, to expose the adhesive layers on the front and back of the product 12. The first label loading device 10 and the second label loading device 11 are used to supply labels to be affixed to the front and back of the product 12, respectively. The first visual labeling device 5 is used to affix the front label of the product 12 to the adhesive layer on the front of the product 12. The flipping device 6 is used to flip the product 12 so that the back of the product 12 faces upwards. The second visual labeling device 8 is used to affix the back label of the product 12 to the adhesive layer on the back of the product 12. The unloading device 9 is used to transfer the finished product out of the conveyor line 2.

[0027] When using the fully automatic visual labeling machine described above, firstly, the product feeding device 3 transfers the products 12 to be labeled one by one onto the conveyor line 2, with the front of the product 12 facing upwards. Simultaneously, the first label feeding device 10 and the second label feeding device 11 place the front label of the product 12 and the back label of the product 12 in designated positions, respectively. Then, the conveyor line 2 conveys the product 12 to the first film-peeling device 4, which peels off the release paper from the front of the product 12 to expose the adhesive layer. Next, the conveyor line 2 conveys the product 12 to the first visual labeling device 5, which picks up the front label of the product 12 and affixes it to the adhesive layer, completing the front labeling of the product 12. Subsequently, the conveyor line 2 conveys the product 12 to the flipping device 6, which flips the product 12 so that the back of the product 12 faces upwards. Next, conveyor line 2 sequentially transports product 12 to the second film-peeling device 7 and the second visual labeling device 8. The second film-peeling device 7 and the second visual labeling device 8 repeat the above operation, affixing the reverse label of product 12 to the adhesive layer on the reverse side of product 12, completing the reverse labeling of product 12. Finally, the unloading device 9 transfers the finished product out of conveyor line 2. It can be seen that this utility model, through the coordinated operation of various devices, realizes fully automated production of double-sided labeling of product 12 with its own adhesive layer, greatly improving production efficiency, reducing manual intervention, reducing labor intensity, and ensuring labeling accuracy and product 12 quality.

[0028] The first label feeding device 10 and the second label feeding device 11 mentioned above can use existing label peeling devices, which can automatically peel the labels off the label strip and realize automatic label feeding.

[0029] See Figure 2and Figure 3 As shown, Figure 2 This is a schematic diagram of the structure of the frame, conveyor line, product feeding device, first film peeling device, first visual labeling device, and flipping device in the embodiment. Figure 3 This is a schematic diagram of the frame, conveyor line, and first film-tearing device in one embodiment. In one implementation of the first film-tearing device 4 and the second film-tearing device 7, both include a tape unwinding roller 41, an unwinding drive mechanism 42, a tape take-up roller 43, a take-up drive mechanism 44, an adhesive roller 45, and an adhesive application drive mechanism 46. The tape unwinding roller 41 is rotatably mounted on the frame 1 and is used to load a roll of tape 47. The unwinding drive mechanism 42 is mounted on the frame 1 by screwing or welding, and its output end is connected to the tape unwinding roller 41 by screwing or welding. The unwinding drive mechanism 42 drives the tape unwinding roller 41 to rotate and unwind the tape 47. The tape take-up roller 43 is rotatably mounted on the frame 1, and the take-up drive mechanism 44 is mounted on the frame 1 by screwing or welding, and its output end is connected to the tape take-up roller 43 by screwing or welding. The winding drive mechanism 44 drives the tape winding wheel 43 to rotate and wind the tape 47. The applicator roller 45 is located above the conveyor line 2 and is used for the tape 47 to pass over. The applicator drive mechanism 46 is mounted on the frame 1 by means of screwing or welding, and its output end is rotatably connected to the applicator roller 45. The applicator drive mechanism 46 drives the applicator roller 45 to move toward or away from the product 12 on the conveyor line 2. Thus, during film removal, the unwinding drive mechanism 42 drives the tape unwinding wheel 41 to rotate and unwind the tape 47, the winding drive mechanism 44 drives the tape winding wheel 43 to rotate and wind the tape 47, and the adhesive application drive mechanism 46 drives the adhesive application roller 45 to move towards the conveyor line 2. Simultaneously, the conveyor line 2 conveys the product 12, and the adhesive application roller 45 presses the tape 47 onto the starting end of the release paper of the product 12. As the product 12 moves with the conveyor line 2, the release paper of the product 12 is peeled off by the tape 47 that bypasses the adhesive application roller 45 and is wound up together with the tape 47 onto the tape winding wheel 43. It can be seen that this film removal device, through the unwinding and winding of the tape 47, the movement of the adhesive application roller 45, and the conveying action of the conveyor line 2, can accurately and efficiently peel off the release paper from the surface of the product 12, ensuring that the release paper is peeled off cleanly and completely, providing a good foundation for subsequent labeling operations.

[0030] Both the unwinding drive mechanism 42 and the rewinding drive mechanism 44 described above can use existing rotary drive mechanisms such as rotary motors or electric motors. The adhesive application drive mechanism 46 described above can use one or two existing linear displacement drive mechanisms such as telescopic cylinders or telescopic poles to drive the displacement of the adhesive application roller 45.

[0031] See Figure 2 and Figure 4 As shown, Figure 4This is a schematic diagram of the frame, conveyor line, and flipping device in one embodiment. In one implementation of the flipping device 6, the flipping device 6 includes a flipping plate 61 and a flipping plate driving mechanism 62. The conveyor line 2 has a clearance channel 21. The flipping plate 61 is rotatably connected to the frame 1 and located within the clearance channel 21. The rotation axis of the flipping plate 61 extends horizontally and is perpendicular to the conveying direction of the conveyor line 2. The flipping plate 61 has at least two limiting slots 611 for inserting a single product 12. The at least two limiting slots 611 are evenly spaced in a ring around the rotation axis of the flipping plate 61. The flipping plate driving mechanism 62 is mounted on the frame 1 by screwing or welding, and its output end is connected to the flipping plate 61 by screwing or welding. The flipping plate driving mechanism 62 drives the flipping plate 61 to rotate around its own rotation axis, so that each limiting slot 611 alternately engages with the conveyor line 2, allowing the product 12 to be input into or output from the engaged limiting slot 611. Thus, after the product 12 is labeled on the front, the flipping plate drive mechanism 62 drives the flipping plate 61 to rotate, so that the opening of one of the limiting grooves 611 aligns with the conveyor line 2 and faces the first visual labeling device 5. The conveyor line 2 can then input the product 12 located at the first visual labeling device 5 into the limiting groove 611. Subsequently, the flipping plate drive mechanism 62 drives the flipping plate 61 to rotate, so that the opening of one of the limiting grooves 611 aligns with the conveyor line 2 and faces the second film-tearing device 7. The conveyor line 2 can then output the product 12 from the limiting groove 611 and transport it to the second film-tearing device 7, achieving flipping. It can be seen that this flipping device 6, through the rotation of the flipping plate 61 and the design of the limiting grooves 611, can continuously and simultaneously flip several products 12, further improving production efficiency.

[0032] The aforementioned flip-plate drive mechanism 62 can use existing rotary motors or other rotary drive mechanisms.

[0033] See Figure 2As shown, in one embodiment of the first visual labeling device 5 and the second visual labeling device 8, both the first visual labeling device 5 and the second visual labeling device 8 include a first detection mechanism 51, a second detection mechanism 52, and a bonding mechanism 53. The first detection mechanism 51 and the second detection mechanism 52 are both mounted on the frame 1 by means of screwing or welding. The first detection mechanism 51 is located above the conveyor line 2 and is used to detect the position of the adhesive layer of the product 12 on the conveyor line 2. The second detection mechanism 52 is located on one side of the conveyor line 2 and is used to detect the position of the label. The bonding mechanism 53 is mounted on the frame 1 by means of screwing or welding. The bonding mechanism 53 is used to pick up the front label or the back label of the product 12 and transfer it to the second detection mechanism 52 for detection. Then, based on the detection results of the first detection mechanism 51 and the second detection mechanism 52, it aligns and presses the front label or the back label of the product 12 onto the adhesive layer of the front or back of the product 12. In this way, the visual labeling device can accurately locate the adhesive layer position and label position of the product 12 through the first detection mechanism 51 and the second detection mechanism 52. Combined with the bonding mechanism 53, the label can be accurately bonded to the adhesive layer of the product 12, ensuring that the label and the adhesive layer of the product 12 are completely overlapped, which greatly improves the accuracy and consistency of labeling and effectively avoids the positional deviation of labeling.

[0034] The first inspection mechanism 51 and the second inspection mechanism 52 mentioned above can use existing visual inspection mechanisms such as CCD cameras, which can quickly and accurately collect the position information of the workpiece. The bonding mechanism 53 mentioned above can be combined with existing three-axis moving mechanisms or robotic arms and other automated equipment with existing gripping heads such as negative pressure suction cups, which can accurately adsorb and grip the label and transfer it to any position.

[0035] See Figure 2As shown, based on the above embodiment, the first detection mechanism 51 is also used to detect the quality of product 12 affixing on the conveyor line 2. Both the first visual labeling device 5 and the second visual labeling device 8 also include a third detection mechanism 54. The third detection mechanism 54 is mounted on the frame 1 by screwing or welding, and is located above the conveyor line 2. The third detection mechanism 54 is located upstream of the first detection mechanism 51 and is used to detect whether there are defects in the appearance of the product 12 on the conveyor line 2. The fully automatic visual labeling machine also includes a defective product unloading device 13. The defective product unloading device 13 is mounted on the frame 1 and located on one side of the conveyor line 2. The defective product unloading device 13 is used to remove unqualified products 12 from the conveyor line 2 based on the detection results of the first detection mechanism 51 and the third detection mechanism 54. Thus, before labeling, the product 12 is first inspected by a third inspection agency 54 to check for defects in its appearance (e.g., whether dust or other stains adhere to the surface of the product 12, especially the adhesive layer). After inspection, the product 12 is conveyed to the area below the first inspection agency 51 via the conveyor line 2. If the third inspection agency 54 passes the inspection, the first inspection agency 51, the second inspection agency 52, and the bonding mechanism 53 work together to accurately bond the label to the adhesive layer of the product 12. After labeling, the first inspection agency 51 checks the bonding quality of the product 12 (e.g., whether the label is accurately positioned, whether it is flat, and whether there are any defects such as air bubbles). If the first inspection agency 51 and / or the third inspection agency 54 fail the inspection, the defective product unloading device 13 can promptly remove the defective product 12, further ensuring the final labeling quality of the product 12, improving the pass rate of the product 12, and reducing the processing costs of subsequent processes.

[0036] The aforementioned third inspection mechanism 54 can use existing visual inspection mechanisms such as CCD cameras to quickly and accurately collect appearance defects of the workpiece. In addition, corresponding light sources can be set in the inspection areas of the aforementioned first inspection mechanism 51, second inspection mechanism 52 and third inspection mechanism 54, which can effectively improve the inspection accuracy of the first inspection mechanism 51, second inspection mechanism 52 and third inspection mechanism 54.

[0037] The aforementioned defective product unloading device 13 can be combined with existing three-axis moving mechanisms or robotic arms and other automated equipment with existing negative pressure suction cups and other gripping heads to accurately pick up defective products 12 from the conveyor line 2 and transfer them to the designated storage location for defective products. For example... Figure 5 As shown, Figure 5 The diagram shows the structure of the frame, conveyor line, defective product unloading device and roller pressing device in this embodiment. In this embodiment, the defective product unloading device 13 is formed by a combination of a rotary cylinder, a lifting cylinder and a negative pressure suction cup.

[0038] See Figure 1As shown, based on any of the above embodiments, the fully automatic visual labeling machine further includes two roller pressing devices 14. Both roller pressing devices 14 are mounted on the frame 1 and are located downstream of the first visual labeling device 5 and the second visual labeling device 8, respectively. The two roller pressing devices 14 are used to press the front and back sides of the product 12, respectively. Thus, the roller pressing devices 14 further compact the label, allowing it to better adhere to the surface of the product 12, enhancing the adhesion, preventing the label from falling off during use, and improving the overall quality and service life of the product 12.

[0039] See Figure 2 and Figure 5 As shown, in one embodiment of the roller pressing device 14, the roller pressing device 14 includes a lifting mechanism 141, a bidirectional displacement mechanism 142, and two pressure rollers 143. The lifting mechanism 141 is mounted on the frame 1 by means of screwing or welding. The bidirectional displacement mechanism 142 is mounted on the output end of the lifting mechanism 141 by means of screwing or welding. The output end of the bidirectional displacement mechanism 142 is rotatably connected to the two pressure rollers 143. The lifting mechanism 141 drives the two pressure rollers 143 to move towards or away from the product 12 on the conveyor line 2, and the bidirectional displacement mechanism 142 drives the two pressure rollers 143 to move towards or away from each other. Thus, during the rolling process, the conveyor line 2 transports the product 12 to below the pressure roller 143; then, the lifting mechanism 141 drives the two pressure rollers 143 to move towards the product 12, so that the pressure rollers 143 abut against the front or back of the product 12; next, the bidirectional displacement mechanism 142 drives the two pressure rollers 143 to reciprocate towards and away from each other, thereby causing the two pressure rollers 143 to roll back and forth on the front or back of the product 12, thus firmly affixing the label to the front or back of the product 12. Furthermore, this structural design of the rolling device 14 allows for flexible adjustment of the rolling position of the pressure rollers 143 according to the size and shape of the product 12, achieving precise rolling of different products 12 and improving the versatility and adaptability of the equipment.

[0040] The aforementioned lifting mechanism 141 can use existing linear displacement drive mechanisms such as telescopic cylinders or telescopic poles, and the aforementioned bidirectional displacement mechanism 142 can use existing bidirectional displacement drive mechanisms such as rotary motor-gear rack and pinion or rotary motor-bidirectional lead screw and nut.

[0041] See Figure 3As shown, in one embodiment of the conveyor line 2, the conveyor line 2 includes a conveyor belt 22 and at least two limiting plates 23. The conveyor belt 22 and the limiting plates 23 are both mounted on the frame 1 by screwing or welding. The conveyor belt 22 carries and conveys the product 12. The limiting plates 23 are symmetrically distributed on both sides of the conveyor belt 22. A limiting channel 24 for limiting the product 12 is formed between the conveyor belt 22 and the at least two limiting plates 23. The conveyor belt 22 has multiple evenly distributed suction holes 221, which communicate with the limiting channel 24. The suction holes 221 are used to adsorb and position the product 12 within the limiting channel 24. Thus, through the action of the limiting plates 23 and the suction holes 221, the conveyor line 2 can accurately limit the position of the product 12, preventing the product 12 from shifting or shaking during conveying, ensuring the positioning accuracy of the product 12 in each process, and providing a strong guarantee for accurate labeling.

[0042] The conveyor belt 22 described above can use an existing motor roller-belt mechanism. The adsorption holes 221 described above can be connected to external vacuum adsorption equipment or other equipment to provide adsorption force.

[0043] See Figure 2 and Figure 6 As shown, Figure 6This is a perspective view of the product loading device in one embodiment. The product loading device 3 includes a storage rack 31, a storage rack drive mechanism 32, a carrier plate 33, a pneumatic component 34, a connecting rod 35, a first lifting mechanism 36, a rotating mechanism 37, a second lifting mechanism 38, and two suction fixtures 39. The storage rack 31 has two storage troughs 311 for stacking and accommodating products 12. The storage rack drive mechanism 32 is mounted on the frame 1 by screwing or welding, and its output end is connected to the storage rack 31 by screwing or welding. The storage rack drive mechanism 32 drives the storage rack 31 to move relative to the conveyor line 2, so that one of the storage troughs 311 aligns with the conveyor line 2. There are two carrier plates 33, which are vertically slidably connected to the two storage troughs 311. The first lifting mechanism 36 is mounted on the storage rack 31 by screwing or welding. A connecting rod 35 is slidably connected between two carrier plates 33. A pneumatic component 34 is mounted on the output end of the first lifting mechanism 36 via screwing or welding, and is connected to the connecting rod 35 for transmission. The pneumatic component 34 drives the connecting rod 35 to slide away from one of the carrier plates 33 and engage with the other carrier plate 33. The first lifting mechanism 36 drives the carrier plate 33 engaged with the connecting rod 35 to move up and down, and the carrier plate 33 drives the product 12 in the corresponding storage tank 311 to move up and down. A rotating mechanism 37 is mounted on the frame 1 via screwing or welding, and a second lifting mechanism 38 is mounted on the output end of the rotating mechanism 37 via screwing or welding. The output end of the second lifting mechanism 38 is connected to two adsorption fixtures 39 via screwing or welding. The adsorption fixtures 39 are used to adsorb or release the product 12. The rotating mechanism 37 drives the adsorption fixtures 39 to alternately face the conveyor line 2 and its docked storage tank 311. The second lifting mechanism 38 is used to drive the adsorption fixture 39 to move up and down toward the conveyor line 2 or the storage tank 311 that are in the opposite position.Thus, when product 12 is loaded, firstly, the storage rack drive mechanism 32 drives the storage rack 31 to move relative to the conveyor line 2, so that one of the storage troughs 311 connects with the conveyor line 2; simultaneously, the pneumatic component 34 drives the connecting rod 35 to insert into the corresponding loading plate 33 of the storage trough 311, and the first lifting mechanism 36 drives the loading plate 33 to rise, which in turn lifts the product 12 in the storage trough 311, moving the uppermost product 12 in the storage trough 311 to the opening of the storage trough 311; then, the rotating mechanism 37 drives the two adsorption fixtures 39 to rotate, so that the two adsorption fixtures 39 are respectively positioned opposite the conveyor line 2 and the storage trough 311; next, the second lifting mechanism 38 drives the two adsorption fixtures 39 to descend toward the conveyor line 2 and the storage trough 311, respectively, and the adsorption fixtures 39 adsorb the storage trough 311. Product 12 at the opening of the trough; then, the second lifting mechanism 38 drives the two adsorption fixtures 39 to rise, and the rotating mechanism 37 drives the two adsorption fixtures 39 to rotate, changing the position of the two adsorption fixtures 39 and transferring the product 12 adsorbed by the adsorption fixtures 39 to the top of the conveyor line 2. At the same time, the first lifting mechanism 36 drives the above-mentioned material plate 33 to rise by the height of one product 12, and moves the uppermost product 12 in the storage tank 311 to the opening of the storage tank 311 again; then, the second lifting mechanism 38 drives the two adsorption fixtures 39 to fall again. The adsorption fixture 39 opposite to the position of the conveyor line 2 releases the product 12 it adsorbs and places the product 12 on the conveyor line 2. The other adsorption fixture 39 adsorbs the product 12 at the opening of the storage tank 311. This process is repeated continuously to transfer the product 12 to the conveyor line 2 one by one. It can be seen that the product feeding device 3 achieves automatic and orderly feeding of product 12 through the coordinated work of multiple mechanisms. It can quickly and accurately transfer product 12 from storage tank 311 to conveyor line 2 one by one, improve feeding efficiency, reduce manual operation, and ensure the continuity of production.

[0044] The two storage tanks 311 can centrally store products 12 of the same specification or type. When the current storage tank 311 facing the conveyor line 2 is empty, other spare storage tanks 311 can be switched to the conveyor line 2 via the storage rack drive mechanism 32, ensuring production continuity while facilitating the filling of empty storage tanks 311. The two storage tanks 311 can also independently store products 12 of different specifications or types. When switching to bonding tasks of other specifications or types of workpieces, the storage rack drive mechanism 32 can connect the corresponding storage tank 311 to the conveyor line 2 for rapid switching of product 12 loading. This avoids production interruptions caused by specification switching in traditional equipment and further improves equipment versatility and production flexibility, meeting diversified production needs. Furthermore, the number of storage tanks 311 can be one or more. If only one is set up, there is no need to set up the storage rack drive mechanism 32, pneumatic component 34 and connecting rod 35. The storage rack 31 can be directly installed on the frame 1 and positioned opposite the conveyor line 2, while the first lifting mechanism 36 can be directly connected to the carrying plate 33. If more than two are set up, the number of carrying plates 33, pneumatic component 34, connecting rod 35 and first lifting mechanism 36 needs to be increased accordingly.

[0045] The aforementioned storage rack drive mechanism 32 and first lifting mechanism 36 can use existing linear displacement drive mechanisms such as servo motor-screw-nut linear modules or servo motor-rack and pinion linear modules. The aforementioned pneumatic component 34 can use existing pneumatic pumps or cylinders, etc., to pneumatically drive the connecting rod 35 to slide between the two carrier plates 33, allowing the connecting rod 35 to disengage from one carrier plate 33 and engage with the other. The aforementioned rotating mechanism 37 can use existing indexing rotary cylinders or rotary motors, etc. The aforementioned second lifting mechanism 38 can use existing telescopic cylinders or telescopic poles, etc., for linear displacement drive mechanisms. The aforementioned suction fixture 39 can use existing negative pressure suction cups or other suction gripping heads.

[0046] See Figure 1 As shown, in one embodiment of the feeding device 9, the feeding device 9 includes a feeding conveyor belt 91 and a palletizing mechanism 92. The feeding conveyor belt 91 is mounted on the frame 1 and is used to receive and transport finished products. The palletizing mechanism 92 is mounted on the frame 1 and located on one side of the conveyor line 2. The palletizing mechanism 92 is used to grab finished products on the conveyor line 2 and stack them on the feeding conveyor belt 91. It can be seen that the feeding device 9, through the cooperation of the feeding conveyor belt 91 and the palletizing mechanism 92, realizes the automatic feeding and palletizing of the product 12, enabling the labeled product 12 to be stacked and transported in an orderly manner, facilitating subsequent packaging and transportation, improving production efficiency, and reducing labor costs.

[0047] The aforementioned unloading conveyor belt 91 can use existing servo motor-belt conveyor mechanisms or servo motor-conveyor chain mechanisms. The aforementioned palletizing mechanism 92 can be combined with existing two-axis moving mechanisms, three-axis moving mechanisms, or robotic arms and other automated equipment with existing negative pressure suction cups and other gripping heads, which can accurately adsorb and grip finished products on the conveyor line 2 and transfer and stack them onto the unloading conveyor belt 91.
