Description

Technical Field

[0001] This invention relates to the field of automotive parts manufacturing technology, and in particular to an automatic resin plate magnetic labeling device and process. Background Technology

[0002] Among existing technologies, sun visors are becoming increasingly popular with consumers due to their advantages such as better applicability, driven by the electrification, intelligentization, and connectivity of new energy vehicles and the ever-evolving customer demands. Traditional sun visors have certain shortcomings in terms of function and practical application. For example, the vanity mirrors on sun visors are not large enough, and the lighting methods and scenarios are relatively limited, failing to adequately meet the needs of drivers and passengers.

[0003] To meet the aforementioned technical requirements, an innovative soft-cover cosmetic mirror sun visor has been designed and developed. During the manufacturing process of the mirror cover, the inner lining needs to be magnetically controlled, thus the production process typically involves multiple steps, including cutting and bonding. However, current production processes may result in unevenness and instability in the product, leading to defects and inconsistencies. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides an automatic magnetic labeling device and process for resin boards that meets the needs of large-scale production and reliably ensures stable and consistent product quality.

[0005] To achieve the above objectives, the present invention provides an automatic magnetic labeling device for resin boards, wherein the resin board has multiple pre-formed holes on its surface, and the magnetic labeling device includes:

[0006] A resin board feeding mechanism is used to sequentially transport resin boards from the resin board hopper to a distant location.

[0007] Multiple magnet pressing assemblies, each corresponding to a pre-drilled hole on a resin plate, the magnet pressing assembly includes a magnet chamber, a magnet pushing mechanism and a pressing head, the magnet chamber is used to store magnets, the magnet pushing mechanism is used to push magnets from the magnet chamber to the pressing position corresponding to the pre-drilled hole, and the pressing head is used to press the magnet pushed to the predetermined pressing position into the pre-drilled hole of the resin plate;

[0008] A double-sided labeling device includes a front labeling mechanism, a back labeling mechanism, and a flipping mechanism. The front labeling mechanism is located at the end of a resin board feeding mechanism and is used to label the front side of the resin board. The flipping mechanism is located between the front labeling mechanism and the back labeling mechanism and is used to flip the resin board after front labeling and convey it to the back labeling mechanism. The back labeling mechanism is located on the other side of the flipping mechanism and is used to label the back side of the resin board.

[0009] The labeling covers at least the surface of the magnet pressed into the pre-drilled hole and the area surrounding the opening of the pre-drilled hole.

[0010] To sequentially push resin boards one by one, the resin board pushing mechanism includes a guide platform, a first push plate, a first push cylinder, and a stop plate. The first push cylinder is located at the starting end of the guide platform; the first push plate is located at the power output end of the first push cylinder and is configured to push the resin boards sequentially from the resin board hopper to the end of the guide platform under the drive of the first push cylinder; the stop plate is located at the end of the guide platform and is used to position and stop the resin board at a predetermined magnetic pressing position, so that each pre-made hole on the resin board corresponds to a magnetic pressing assembly.

[0011] To ensure accurate magnet pressing, each magnet pushing mechanism includes a magnetic guide plate, a second pushing plate, a second pushing cylinder, and a third pushing cylinder. The magnetic guide plate is located at the end of the guide platform and above the predetermined stopping position of the resin plate. The bottom surface of the magnetic guide plate has a magnetic feeding channel adapted to the width of the magnet, which connects the magnet chamber and the pre-formed hole. The second pushing plate is located at the power output end of the second pushing cylinder and is configured to push the magnets sequentially from the magnet chamber through the magnetic feeding channel to the predetermined pressing position under the drive of the second pushing cylinder. The upper surface of the magnetic guide plate has a pressing port communicating with the pre-formed hole. The pressing head is located directly above the pressing port and is configured to press the magnet pushed to the predetermined pressing position into the corresponding pre-formed hole under the drive of the third pushing cylinder.

[0012] To avoid incorrect pushing and pressing, a magnetic pole sensor is installed below the discharge port of the magnet bin. The magnetic pole sensor is used to detect whether the magnetic pole of the magnet currently being fed into the magnet bin is consistent with the magnetic pole required for the current pre-made hole, and outputs an alarm signal when they are inconsistent.

[0013] To prevent the magnet from becoming misaligned during the pushing process, the width of the magnet delivery channel is adapted to the width of the second push plate, and the free end of the second push plate is provided with a locking position adapted to the shape of the magnet.

[0014] To reduce the attraction and stretching of the magnet by the magnetic head resetting after the magnet is pressed in, the opening area of ​​the magnetic pressing port is smaller than the opening area of ​​the pre-made hole, and a magnetic baffle is provided inside the magnetic pressing port. The magnetic head is provided with a notch that matches the magnetic baffle.

[0015] To allow for uncontrolled movement of the magnets within the magnet compartment, a guide rod is provided on the side of the magnet compartment. A spring and a magnetic pressure plate are threaded through the guide rod. One end of the spring is fixed to the top of the guide rod, and the other end abuts against the upper surface of the magnetic pressure plate. The magnetic pressure plate extends into the magnet compartment from the side opposite to the guide rod and is configured to press down on the magnets located inside the magnet compartment under the elastic action of the spring.

[0016] For efficient label application, the front labeling mechanism includes a conveyor belt, a first drive motor, a film roll, a film roll recovery belt, a tension roller assembly, and a label pressing roller. The conveyor belt is located at the end of the resin plate feeding mechanism. The label is a transparent adhesive tape prepared in the shape of a label and adhered to the film roll. The tension roller assembly has a head steel plate angled to the conveyor belt. The film roll passes through the tension roller assembly and the head steel plate and then connects to the film roll recovery belt. The first drive motor drives the tension roller assembly and the film roll so that the label reaches the end of the head steel plate and is peeled off from the film roll and adhered to the surface of the magnet in the pre-made hole and the area around the opening of the pre-made hole. The label pressing roller is located at the end of the conveyor belt and has a clearance fit with the conveyor belt. The structure of the back labeling mechanism is the same as that of the front labeling mechanism.

[0017] To achieve simple and effective flipping of the resin board, the flipping mechanism includes a second drive motor and a flipping wheel. The flipping wheel is fixedly connected to the power output end of the second drive motor, and multiple wheel grooves are evenly distributed on the circumferential surface of the flipping wheel.

[0018] On the other hand, the present invention also provides an automatic magnetic labeling process for resin boards, which uses the automatic magnetic labeling device for resin boards described in the above scheme and is prepared according to the following steps:

[0019] A) The resin plates are sequentially transported from the resin plate hopper to the predetermined magnetization position via the resin plate feeding mechanism. The specific steps are as follows:

[0020] ① The first propulsion cylinder drives the first propulsion plate to push the resin board away from the resin board hopper and into the guide platform;

[0021] ② The first pusher plate performs a reciprocating pushing motion, sequentially pushing the resin plate to the end of the guide platform;

[0022] ③ The stop plate extends to position and fix the resin plate at the end of the guide table at the predetermined magnetic position.

[0023] B) For each pre-drilled hole on the resin plate, press-fitting is performed using the corresponding magnetic pressing assembly. The specific steps are as follows:

[0024] ① The magnetic pole sensor determines whether the magnetic pole of the magnet being fed into the magnet bin is consistent with the magnetic pole required for the current press-fit pre-formed hole, and outputs an alarm signal when they are inconsistent;

[0025] ②The second propulsion cylinder drives the second propulsion plate to advance through the bayonet position and lock the magnet;

[0026] ③ The second pusher plate continues to advance, pushing the magnet along the magnetization channel to the predetermined magnetization position;

[0027] ④ Driven by the third propulsion cylinder, the pressing head is aligned with the pressing port and lowered to press the magnet into the pre-made hole;

[0028] ⑤ The magnetic head resets, the stop plate retracts, and the first push plate pushes the resin plate that has completed magnetic pressing to the front labeling mechanism.

[0029] C) Use the front labeling mechanism to apply the first label to the front of the resin board to cover the pressed magnet. The specific steps are: ① The conveyor belt transports the resin board with the pressed magnet to the bottom of the head steel plate.

[0030] ② The first drive motor drives the film roll and tension roller assembly to peel the film roll off the film roll;

[0031] ③ The tensioning roller group guides the conveyor belt to the location of the pre-made hole in the resin plate through the head steel plate;

[0032] ④ After the label reaches the far end of the steel plate, peel it off the tape and stick it to the magnet surface and the area around the pre-made hole opening to fix the magnet.

[0033] ⑤ The label roller presses the resin plate that has been labeled on the conveyor belt;

[0034] D) The resin board that has completed its first labeling is flipped using a resin board flipping mechanism. The specific steps are as follows:

[0035] ① The second drive motor drives the tilting wheel to rotate;

[0036] ②The resin plate with the label applied slides into the groove of the turning wheel;

[0037] ③ As the rotating wheel rotates, the resin board is flipped to face one side;

[0038] ④ The second drive motor continues to rotate, conveying the flipped resin board to the reverse labeling mechanism;

[0039] E) Use the reverse labeling mechanism to apply a second label to the reverse side of the resin board, completing the automatic magnetic labeling process of the resin board.

[0040] The automatic magnetic labeling device and process for resin boards designed in this invention achieves efficient resin board conveying, magnetic application, and labeling through mechanical structure design. It can meet the needs of large-scale production and, while achieving mass production, reliably ensures stable and consistent product quality by reducing human intervention, thus lowering the possibility of product quality problems. Its unique magnetic structure design ensures a more secure magnet fixation and a superior labeling effect, further improving the quality of the finished resin board. The device and method also have the flexibility to adapt to the production of resin boards of different specifications, enhancing the applicability of the production line and making it widely applicable to different production needs.

[0052] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0053] Example 1.

[0054] like Figure 1-10 As shown, in one aspect, this embodiment provides an automatic magnetic labeling device for resin boards, wherein the resin board has multiple pre-made holes on its surface, and the magnetic labeling device includes:

[0055] The resin board feeding mechanism 10 is used to sequentially transport resin boards from the resin board hopper 4 to the far end.

[0056] Multiple magnet pressing assemblies 20, each magnet pressing assembly 20 corresponding to a pre-made hole on a resin plate. Each magnet pressing assembly 20 includes a magnet chamber 1, a magnet pushing mechanism 2, and a pressing head 3. The magnet chamber 1 is used to store magnets, the magnet pushing mechanism 2 is used to push the magnets from the magnet chamber 1 to the pressing position corresponding to the pre-made hole, and the pressing head 3 is used to press the magnets pushed to the predetermined pressing position into the pre-made hole of the resin plate.

[0057] A double-sided labeling device includes a front labeling mechanism 30, a back labeling mechanism 40, and a flipping mechanism 50. The front labeling mechanism 30 is located at the end of the resin board feeding mechanism 10 and is used to label the front side of the resin board. The flipping mechanism 50 is located between the front labeling mechanism 30 and the back labeling mechanism 40 and is used to flip the resin board after front labeling and convey it to the back labeling mechanism 40. The back labeling mechanism 40 is located on the other side of the flipping mechanism 50 and is used to label the back side of the resin board.

[0058] The labeling covers at least the surface of the magnet pressed into the pre-drilled hole and the area surrounding the opening of the pre-drilled hole.

[0059] Figure 10 shows the resin board 100 provided in this embodiment, which has multiple pre-drilled holes 200 on its surface. During operation, the resin board hopper 4 stores the resin board 100, and the magnet hopper 1 stores the magnets 300. The resin board pushing mechanism 10 sequentially transports the resin boards 100 from the resin board hopper 4 to the magnet pressing assembly 20. Then, the magnet pushing mechanism 2 pushes the magnets 300 from the magnet hopper 1 to the pressing positions corresponding to the pre-drilled holes 200. Next, the pressing head 3 presses the magnets 300 pushed to the predetermined pressing positions into the pre-drilled holes 200 of the resin board 100. In this embodiment, multiple notches are spaced apart on the inner side of the pre-drilled holes 200 so that when the magnets 300 are pressed into the pre-drilled holes 200, they form a local interference fit with the resin board 100, ensuring a tight fit. To ensure the tightness of the assembly between the magnet 300 and the resin plate 100, and to prevent the magnet 300 from being crushed due to excessive pressing force from the magnetic head 3, multiple magnet pressing components 20 are used to simultaneously press the magnets into multiple pre-drilled holes 200. Then, a front labeling mechanism 30 is used to apply a label 400 to the front of the resin plate 100. A flipping mechanism 50 flips the resin plate 100 after front labeling and transfers it to a back labeling mechanism 40, which applies a label to the back of the resin plate. This label 400 covers the pressed magnet 300 and the area around the opening of the pre-drilled hole 200, preventing the magnets 300 from overlapping and detaching from the pre-drilled hole 200 during subsequent processing. This process ensures that the magnets 300 will not tilt or fail due to adsorption force in the subsequent use of the finished magnetic soft cover made from the resin plate 100, reducing human intervention, reliably guaranteeing product quality consistency, and lowering the possibility of product quality problems.

[0060] Additionally, in this embodiment, as Figure 3 As shown, the automatic magnetic labeling device for resin boards can be set up in multiple sets according to the actual number of resin boards required for the magnetic soft cover of the sunshade, such as... Figure 3 The automatic magnetic labeling device for resin boards shown is configured with two synchronous lines, one above the other, to achieve simultaneous production of two resin boards of different specifications.

[0061] Specifically, in this embodiment, as Figure 4 As shown, in order to sequentially push the resin plates 100 one by one, the resin plate pushing mechanism 10 includes a guide platform 11, a first pushing plate 12, a first pushing cylinder 13, and a stop plate 14. The first pushing cylinder 13 is located at the starting end of the guide platform 11; the first pushing plate 12 is located at the power output end of the first pushing cylinder 13 and is configured to push the resin plates from the resin plate hopper 4 sequentially to the end of the guide platform 11 under the drive of the first pushing cylinder 13; the stop plate 14 is located at the end of the guide platform 11 and is used to position and stop the resin plates at a predetermined magnetic pressing position so that each pre-made hole on the resin plate corresponds to a magnet pressing assembly 20.

[0062] At work, such as Figure 4 As shown, the guide platform 11 is set at the outlet of the resin board hopper 4, providing a flat surface for the falling resin board 100 so that the resin board 100 can slide smoothly. The first push plate 12 is configured at the power output end of the first push cylinder 13. Then, driven by the first push cylinder 13, the first push plate 12 pushes the resin board 100 one by one from the outlet of the resin board hopper 4 to the end of the guide platform 11, that is, the area where the stop plate 14 is located. It should be noted that in this embodiment, the stop plate 14 is a motor-driven retractable stop plate. Specifically, the hole position sensor 80 (generally red) on the guide platform 11 When the external photoelectric sensor detects that the resin plate 100 (pre-drilled hole 200) has reached the predetermined magnetic pressing position, the stop plate 14 is automatically raised to block the resin plate 100. Then, the magnet pressing assembly 20 corresponding to each pre-drilled hole is activated to press the magnet 300. After the magnet 300 is pressed, the stop plate 14 retracts, and the first push plate 12 pushes the resin plate 100 forward, so that the pressed resin plate 100 automatically enters the double-sided labeling device for the labeling process. The resin plates without pressed magnets continue to move to the magnetic pressing position under the drive of the first push plate 12, and the stop plate 14 continues to rise, repeating the above action steps. This integrated production line design helps to reduce interruptions in the production process and improve overall manufacturing efficiency.

[0063] In this embodiment, as Figure 6 As shown, to ensure the accuracy of magnet pressing, each magnet pushing mechanism 2 includes a magnetic guide plate 21, a second pushing plate 22, a second pushing cylinder 23, and a third pushing cylinder 24. The magnetic guide plate 21 is located at the end of the guide platform 11 and above the predetermined stopping position of the resin plate. The bottom surface of the magnetic guide plate 21 is provided with a magnet feeding channel 25 adapted to the width of the magnet. The magnet feeding channel 25 is used to connect the magnet chamber 1 and the pre-made hole. The second pushing plate 22 is located at the power output end of the second pushing cylinder 23 and is configured to push the magnets from the magnet chamber 1 one by one through the magnet feeding channel 25 to the predetermined pressing position under the drive of the second pushing cylinder 23. The upper surface of the magnetic guide plate 21 is provided with a pressing port 211 communicating with the pre-made hole. The pressing head 3 is located directly above the pressing port 211 and is configured to press the magnet pushed to the predetermined pressing position into the corresponding pre-made hole under the drive of the third pushing cylinder 24.

[0064] At work, such as Figure 6As shown, when the resin plate 100 is pushed to the predetermined magnetic pressing position, the magnetic guide plate 21 is set at the end of the guide table 11 and above the stopping position (magnetic pressing position) of the resin plate 100, so that the magnetic delivery channel 25 connects the magnet chamber 1 and the pre-made hole 200 reaching the magnetic pressing position. Then, the second propulsion cylinder 23 moves to drive the second propulsion plate 22 forward (in the area where the resin plate 100 is located), pushing the magnet 200 out of the magnet chamber 1. The pushed-out magnet 300 is attracted to the magnetic guide plate 21. The resin plate 100 is pushed upwards along the magnetization channel 25 by the second pusher plate 22 until it reaches the pre-drilled hole 200 and stops (at the extreme position at the end of the magnetization channel 25). Then, the third pusher cylinder 24 actuates, driving the pressing head 3 to pass through the pressing port 21 and press down, pressing the magnet 300 into the pre-drilled hole 200. After the pressing head 3 resets, the stop plate 14 retracts, and the first pusher plate 12 actuates to push the magnetized resin plate 100 to the front labeling mechanism, completing the magnetization process of the resin plate 100. In summary, through the coordinated action of the first pusher plate 12, the second pusher plate 22, and the third pusher cylinder 24, continuous pushing of the resin plate 100 and continuous pressing of the magnet 300 are achieved. This uninterrupted workflow improves production efficiency, reduces production cycle time, and reduces dependence on operators.

[0065] In some embodiments, such as Figure 8 As shown, to avoid incorrect pushing and pressing, a magnetic pole sensor 26 is installed below the discharge port of the magnet chamber 1. The magnetic pole sensor 26 is used to detect whether the magnetic pole of the magnet currently being fed into the magnet chamber 1 matches the magnetic pole required for the current pre-drilled hole, and outputs an alarm signal when there is a mismatch. In this embodiment, by setting up the magnetic pole sensor 26, the magnetic pole status of the magnet currently being fed into the magnet chamber 1 can be detected in real time. If the magnetic pole of the currently being fed into the magnet is detected to be inconsistent with the magnetic pole required for the current pre-drilled hole, the magnetic pole sensor 26 will immediately output an alarm signal. This helps on-site personnel to promptly detect potential errors or abnormalities and take corresponding measures to avoid incorrect pushing and pressing, thus preventing the manufacture of products that do not meet specifications.

[0066] In some embodiments, such as Figure 5 and Figure 7As shown, to prevent the magnet from becoming misaligned during the pushing process, the width of the magnetizing channel 25 is adapted to the width of the second pusher plate 22, and the free end of the second pusher plate 22 is provided with a locking position 221 adapted to the shape of the magnet. In specific implementation, the second pusher cylinder 23 drives the second pusher plate 22 to advance and lock the magnet 300 through the locking position 221. Then, the second pusher plate 22 pushes the magnet 300 to the predetermined pressing position along the magnetizing channel 25 adapted to it. This structure, through the pre-fixation of the magnet 300 by the locking position 221, avoids the magnet 300 from tilting or deviating during the pushing process, ensuring that it enters the pressing position according to the predetermined trajectory. In addition, in this embodiment, to ensure the durability of the mechanism, the second pusher plate 22 is made of high-strength spring steel, and its thickness is slightly less than the thickness of the magnet 300, ensuring smooth pushing action.

[0067] In some embodiments, such as Figure 4 and Figure 6 As shown, in order to reduce the attraction and stretching of the magnet by the magnetic head 3 after the magnet is pressed in, the opening area of ​​the magnetic pressing port 211 is smaller than the opening area of ​​the pre-made hole, and a magnetic blocking rib 212 is provided in the magnetic pressing port 211. The magnetic head 3 has a notch that matches the magnetic blocking rib 212. In specific implementation, when the magnet 300 is pressed into the corresponding pre-drilled hole 200 by the pressing head 3, it may flip or shift due to adsorption. Or, during the pressing process, the magnet 300 may be adsorbed onto the pressing head 3 and may be adsorbed away when the pressing head 3 resets. However, by utilizing the structural design that the opening area of ​​the pressing port 211 is smaller than the opening area of ​​the pre-drilled hole 200, the adsorption effect of the pressing head 3 on the magnet 300 can be reduced. At the same time, the magnetic baffle 212 set in the pressing port 211 makes the pressing port 211 form a double hole, and the pressing head 3 is adapted to form a double head, which can further reduce the adsorption effect of the pressing head 3 on the magnet 300. This reduces the adsorption and stretching of the magnet 300 by the pressing head 3 when it resets after the magnet 300 is pressed in. The magnetic baffle 212 also assists in the pressing of the magnet 300 and the separation of the magnet 300 when the pressing head 3 resets.

[0068] In some embodiments, such as Figure 4 heat exchange Figure 6As shown, to prevent uncontrolled movement of the magnets within the storage chamber, a guide rod 60 is provided on the side of the magnet storage chamber 1. A spring 61 and a magnetic pressing plate 62 are threaded onto the guide rod 60. One end of the spring 61 is fixed to the top of the guide rod 60, and the other end abuts against the upper surface of the magnetic pressing plate 62. The magnetic pressing plate 62 extends into the magnet storage chamber 1 from the side opposite to the guide rod 60 and is configured to press down on the magnets located in the magnet storage chamber 1 under the elastic action of the spring 61. With this structural design, the guide rod 60 and the connected spring 61 and magnetic pressing plate 62 form a guiding and fixing mechanism. That is, as the amount of magnetic material in the magnet storage chamber 1 decreases, the magnetic pressing plate 62, under the elastic action of the spring 61, can continuously press down on the magnets located in the magnet storage chamber 1 to a certain extent, ensuring the relative stability of the magnets' positions and preventing unnecessary movement or deviation within the storage chamber, thus reducing the potential negative impact of uncontrolled movement on the system. In addition, in this embodiment, a low-position sensor 70 is also provided at the bottom of the magnet compartment 1. When the magnet in the magnet compartment 1 reaches the low position, the low-position sensor 70 detects and alarms, reminding the operator to add magnets in time to ensure that the equipment continues to produce automatically without stopping.

[0069] In some embodiments, such as Figure 2 As shown, for efficient label application, the front labeling mechanism 30 includes a conveyor belt 31, a first drive motor 32, a film roll 33, a film roll recycling belt 34, a tension roller assembly 35, and a label pressing roller 36. The conveyor belt 31 is located at the end of the resin plate feeding mechanism 10. The label is a transparent adhesive tape prepared in the shape of a label and adhered to the film roll 33. The tension roller assembly 35 has a head steel plate 37 that is angled to the conveyor belt 31. The film roll 33 passes through the tension roller assembly 35 and the head steel plate 37 and then connects to the film roll recycling belt 34. The first drive motor 32 drives the tension roller assembly 35 and the film roll 33 so that the label reaches the end of the head steel plate 37 and is peeled off from the film roll 33 and adhered to the surface of the magnet in the pre-made hole and the surrounding area of ​​the pre-made hole opening. The label pressing roller 36 is located at the end of the conveyor belt 31 and is clearance-fitted with the conveyor belt 31. The structure of the back labeling mechanism 40 is the same as that of the front labeling mechanism 30.

[0070] In practice, the conveyor belt 31 is positioned at the end of the guide platform 11 and slightly below its horizontal plane to ensure that the magnetized resin plate 100 smoothly enters the conveyor belt 31. The conveyor belt 31 then transports the resin plate 100 with the magnet 300 pressed onto it to below the head steel plate 37. At this point, the infrared detection device 500 located on the belt senses the resin plate 100 as it is transmitted to the infrared sensing area. The first drive motor 32 then drives the film roll 33 and the tension roller assembly 35 to peel the film roll 33 off. The tension roller assembly 35 then guides the film roll through the head steel plate 37 to the location of the pre-drilled hole 200 on the resin plate 100. Since the head steel plate 37 is angled relative to the conveyor belt 31... After the tape reaches the turning point at the far end of the head steel plate 37 (the end closest to the resin plate 100), the label 400 is gradually peeled off from the tape and gradually adhered to the surface of the magnet 300 and the area around the opening of the pre-drilled hole 200 as the resin plate 100 moves forward, thereby further fixing the magnet 300 to the resin plate 100. As the conveyor belt 31 runs, the labeled resin plate 100 is transported to the area where the label roller 36 is located. In this embodiment, the label roller 36 is set to a free-rolling state, and the gap between its roller surface and the conveyor belt 31 is slightly smaller than the thickness of the resin plate 100, so that when the resin plate 100 passes through the label roller 36, the label 400 can be pressed firmly in a free-adhered state, ensuring that there are no air bubbles inside after the label 400 is firmly adhered. In addition, in this embodiment, an infrared detection device 600 can also be set at the end of the conveyor belt 31 to sense whether there are any missing or crooked labels 400 on the surface of the resin plate 100; if there is a defect, an alarm signal is output to help the operator find the problem in time. In this embodiment, the structure of the reverse labeling mechanism 40 is the same as that of the front labeling mechanism 30, and their working principle and steps are the same, so they will not be described again here.

[0071] In some embodiments, such as Figure 2 and Figure 9 As shown, to achieve simple and effective resin board flipping, the flipping mechanism 50 includes a second drive motor 51 and a flipping wheel 52. The flipping wheel 52 is fixedly connected to the power output end of the second drive motor 51, and multiple grooves 53 are evenly distributed on the circumferential surface of the flipping wheel 52. In specific implementation, after the resin board 100 is labeled on the front side, it is conveyed by the conveyor belt 31 into the groove 53 of the flipping wheel 52. The flipping wheel 52 rotates continuously through the second drive motor 51, flipping the resin board 100 so that it falls onto the conveyor belt of the reverse labeling mechanism 40 and continues to be conveyed forward to achieve double-sided labeling. The flipping mechanism with this structure is relatively simple and easy to implement and maintain.

[0072] On the other hand, this embodiment also provides an automatic magnetic labeling process for resin boards, which uses the automatic magnetic labeling device for resin boards described in the above scheme and is prepared according to the following steps:

[0073] A) The resin plates are sequentially transported from the resin plate hopper to the predetermined magnetization position via the resin plate feeding mechanism. The specific steps are as follows:

[0074] ① The first propulsion cylinder drives the first propulsion plate to push the resin board away from the resin board hopper and into the guide platform;

[0075] ② The first pusher plate performs a reciprocating pushing motion, sequentially pushing the resin plate to the end of the guide platform;

[0076] ③ The stop plate extends to position and fix the resin plate at the end of the guide table at the predetermined magnetic position.

[0077] B) For each pre-drilled hole on the resin plate, press-fitting is performed using the corresponding magnetic pressing assembly. The specific steps are as follows:

[0078] ① The magnetic pole sensor determines whether the magnetic pole of the magnet being fed into the magnet bin is consistent with the magnetic pole required for the current press-fit pre-formed hole, and outputs an alarm signal when they are inconsistent;

[0079] ②The second propulsion cylinder drives the second propulsion plate to advance through the bayonet position and lock the magnet;

[0080] ③ The second pusher plate continues to advance, pushing the magnet along the magnetization channel to the predetermined magnetization position;

[0081] ④ Driven by the third propulsion cylinder, the pressing head is aligned with the pressing port and lowered to press the magnet into the pre-made hole;

[0082] ⑤ The magnetic head resets, the stop plate retracts, and the first push plate pushes the resin plate that has completed magnetic pressing to the front labeling mechanism.

[0083] C) Use the front labeling mechanism to apply the first label to the front of the resin board to cover the pressed magnet. The specific steps are: ① The conveyor belt transports the resin board with the pressed magnet to the bottom of the head steel plate.

[0084] ② The first drive motor drives the film roll and tension roller assembly to peel the film roll off the film roll;

[0085] ③ The tensioning roller group guides the conveyor belt to the location of the pre-made hole in the resin plate through the head steel plate;

[0086] ④ After the label reaches the far end of the steel plate, peel it off the tape and stick it to the magnet surface and the area around the pre-made hole opening to fix the magnet.

[0087] ⑤ The label roller presses the resin plate that has been labeled on the conveyor belt;

[0088] D) The resin board that has completed its first labeling is flipped using a resin board flipping mechanism. The specific steps are as follows:

[0089] ① The second drive motor drives the tilting wheel to rotate;

[0090] ②The resin plate with the label applied slides into the groove of the turning wheel;

[0091] ③ As the rotating wheel rotates, the resin board is flipped to face one side;

[0092] ④ The second drive motor continues to rotate, conveying the flipped resin board to the reverse labeling mechanism;

[0093] E) Use the reverse labeling mechanism to apply a second label to the reverse side of the resin board, completing the automatic magnetic labeling process of the resin board.

[0094] The automatic resin board magnetic labeling device and process provided in this embodiment achieves efficient resin board conveying, magnetic labeling, and labeling through mechanical structure design. It can meet the needs of large-scale production and, while achieving mass production, reliably ensures stable and consistent product quality by reducing human intervention, thus reducing the possibility of product quality problems.
