Description

Technical Field

[0001] The invention relates to the field of semiconductor technology, and in particular to an automatic winding and unwinding device. Background Art

[0002] In modern electronic manufacturing, roll-to-roll technology is widely used, especially in the production process involving flexible circuits and display technologies. COF (Chip On Film) technology has become a key process in display manufacturing and other electronic products due to its advantages in improving circuit density and flexibility. In these applications, COF tapes are usually transported and handled in roll form.

[0003] In the traditional production process, the processing of COF tapes usually requires manual intervention. Specifically, during production, the COF tapes need to be pulled out from the tray, tested or otherwise processed, and then recycled back into the tray. In addition, the protective film on the original COF tape needs to be recycled into a tray first, and a new tray of protective film tape needs to be used for synchronous recycling when the COF is collected. This method not only increases costs, but also increases the time for manual loading and unloading of the tray, affecting production efficiency.

[0004] BACKGROUND OF THE INVENTION The above information disclosed is only for understanding the background of the inventive concept and may contain information that does not constitute the prior art. Summary of the invention

[0005] Based on this, it is necessary to provide an automatic winding and unwinding device to address the above problems.

[0006] An automatic winding and unwinding device, comprising:

[0007] frame;

[0008] A material discharging tray, which is arranged on the frame and used for winding the stacked material strips and protective films;

[0009] A material receiving tray, wherein the material discharging tray is arranged on the frame;

[0010] A material belt guide mechanism, wherein the material belt guide mechanism is used for winding the supply belt, one end of the material belt is wound around the unwinding tray, and the other end of the material belt is connected to the receiving tray after winding through the material belt guide mechanism and is rewound around the receiving tray;

[0011] A protective film guiding mechanism is used for winding the protective film, one end of the protective film is wound on the discharge tray and stacked with the material tape, and the other end of the protective film is connected to the receiving tray after being wound through the protective film guiding mechanism and is stacked again with the material tape.

[0012] The above automatic winding and unwinding equipment can at least achieve the following beneficial effects:

[0013] The unwinding tray of the automatic unwinding and rewinding equipment releases the protective film and the material tape, and after the protective film and the material tape are peeled off, they go to two different conveying routes. The material tape can be guided by the material tape guide mechanism, and can be recycled and wound on the receiving tray again after completing the inspection or other processing. The protective film can be guided by the protective film guide mechanism and re-stacked and wound on the receiving tray together with the material tape, that is, the protective film can be recycled. Through the unique guiding design, the automatic unwinding and rewinding equipment can efficiently separate and recycle the material tape and the protective film. The protective film can be rewound and recycled synchronously with the material tape after use, avoiding waste, realizing the recycling of materials, and significantly reducing the cost of production materials. The automatic unwinding and rewinding equipment realizes the automatic unwinding and rewinding process of the material tape and the protective film. The automated operation process reduces the time of loading and unloading, allowing the production line to operate at a higher speed, which not only reduces labor costs, but also reduces the operating errors caused by human factors, and improves the stability and reliability of the production line. At the same time, the equipment can replace the material tape and the protective film without stopping the machine, further improving production efficiency.

[0014] In some embodiments, the number of the material belt guide mechanisms is set to two, one material belt guide mechanism is used to guide the material belt released from the material discharge tray, and the other material belt guide mechanism is used to guide the material belt to the material receiving tray, each of the material belt guide mechanisms includes a fixed plate, a guide rail, a guide seat, a first guide wheel and a second guide wheel arranged on the frame, the first guide wheel is rotatably arranged on the fixed plate, the guide rail is arranged on the fixed plate, the guide seat is slidably arranged on the guide rail, the second guide wheel is rotatably arranged on the guide seat, the guide seat can slide along the guide rail and drive the second guide wheel to approach or move away from the first guide wheel, and the second guide wheel can move to a first position and a second position driven by the guide seat; in the first position, the material belt is clamped between the outer circumference of the first guide wheel and the outer circumference of the second guide wheel; in the second position, the outer circumference of the first guide wheel and the outer circumference of the second guide wheel are arranged at intervals, so as to allow the material belt to be taken and placed between the outer circumference of the first guide wheel and the outer circumference of the second guide wheel. This design achieves more accurate and flexible material belt guiding and control by setting a fixed plate, a guide rail, a guide seat, a first guide wheel and a second guide wheel in each material belt guiding mechanism. The first guide wheel is rotatably arranged on the fixed plate, and the guide seat is slidably arranged on the guide rail, and drives the second guide wheel to approach or move away from the first guide wheel. The guide seat can slide along the guide rail, so that the second guide wheel can move to the first position and the second position driven by the guide seat. In the first position, the material belt is clamped between the outer peripheral surfaces of the first guide wheel and the second guide wheel, ensuring the stable transmission and precise positioning of the material belt. In the second position, the outer peripheral surfaces of the first guide wheel and the second guide wheel are spaced apart, providing a convenient space for taking and placing the material belt. This design not only improves the stability and accuracy of the material belt during transmission, but also simplifies the loading and unloading operations of the material belt, and improves the operating efficiency and flexibility of the overall equipment.

[0015] In some embodiments, the material belt guide mechanism further includes an elastic member, one end of which is fixed to the fixed plate, and the other end of which is fixed to the guide seat, and the elastic member is used to provide a pulling force to make the guide seat slide in the direction close to the first guide wheel. In this embodiment, two material belt guide mechanisms are provided, one of which is used to guide the material belt released from the material discharge tray, and the other is used to guide the material belt to the material receiving tray. One end of the elastic member is fixed to the fixed plate, and the other end is fixed to the guide seat, providing a continuous pulling mechanism. This pulling force causes the guide seat to slide naturally in the direction close to the first guide wheel. This design ensures that during the material belt transmission process, the guide seat is always maintained in a position that is conducive to the stable transmission of the material belt, and the material belt can always be maintained between the first guide wheel and the second guide wheel during the transmission process, thereby reducing the potential error caused by the loosening or deviation of the material belt. In addition, the use of elastic members can also absorb and alleviate the vibration or impact that may occur during the transmission process, thereby improving the durability and reliability of the entire system. This not only improves the accuracy and stability of the material belt guiding, but also simplifies the adjustment and maintenance process of the equipment, making the operation more efficient and convenient.

[0016] In some embodiments, the material belt guiding mechanism also includes an operating member provided on the guide seat, and the operating member is used for operating to drive the guide seat to slide on the guide rail. By providing the operating member on the guide seat, convenient control of the guide seat sliding on the guide rail is achieved. The operating member is mounted on the guide seat and is designed to manually or automatically adjust the position of the guide seat. By operating the operating member, the user can easily adjust the position of the guide seat on the guide rail and adjust the distance between the first guide wheel and the second guide wheel. This design is particularly suitable for production environments that require frequent replacement of material belts or adjustment of material belt paths. By simplifying the operating process, the adjustment time is reduced and the production efficiency is improved.

[0017] In some embodiments, the automatic winding and unwinding device also includes a material belt tensioning mechanism disposed on the frame and located below the material belt guiding mechanism, the material belt tensioning mechanism includes a first slide rail, a first slider, and a first tensioning wheel, the first slide rail is vertically disposed on the frame, the first slider is slidably disposed on the first slide rail, the first tensioning wheel is rotatably disposed on the first slider, the side of the first tensioning wheel facing away from the material belt guiding mechanism is used for the material belt to abut and wind, and the first slider and the first tensioning wheel can have a tendency to slide downward along the first slide rail under the action of gravity to tension the material belt. The material belt tensioning mechanism includes a first slide rail vertically disposed on the frame, a first slider slidably disposed on the slide rail, and a first tensioning wheel rotatably disposed on the slider. The design of the first tensioning wheel allows the side of the first tensioning wheel facing away from the material belt guiding mechanism to abut and wind the material belt, thereby providing the necessary tensioning force during the material belt transmission process. Since the first slider and the first tensioning wheel have a tendency to slide down along the first slide rail under the action of gravity, this natural gravity-driven mechanism effectively provides continuous tension for the material belt, ensuring the stability and consistency of the material belt during transmission. This design can automatically adjust the tension of the material belt, reduce the need for human intervention, and improve the automation and operating efficiency of the system. At the same time, this design also helps prevent the material belt from loosening or slipping, extending the service life of the equipment and reducing maintenance costs.

[0018] In some embodiments, the material belt tensioning mechanism further includes a first pulley, a first traction rope and a first counterweight. The first pulley is arranged on the frame and is not lower than the first tensioning wheel in the height direction. The first traction rope is wound and abuts against the side of the first pulley facing away from the ground. One end of the first traction rope is fixed to the first slider, and the other end of the first traction rope is connected to the first counterweight. The pulling force of the first traction rope on the first slider can offset part of the gravity of the first slider and the first tensioning wheel and achieve balance. The weight of the first counterweight is set to be able to change under external operation to adjust the pulling force of the first traction rope on the first slider, thereby adjusting the tension of the first tensioning wheel on the material belt. The material belt tensioning mechanism further enhances the precise control and flexible adjustment of the material belt tension by introducing the first pulley, the first traction rope and the first counterweight. The first pulley is arranged on the frame, and its position is higher than or equal to the first tensioning wheel in the height direction to ensure that the traction rope can be wound smoothly and provide appropriate tension. One end of the first traction rope is fixed to the first slider, and the other end is connected to the first counterweight. The traction rope passes through the side of the pulley facing away from the ground, and the mechanical advantage of the pulley is used to change the traction direction. With this design, the tension applied by the first traction rope on the first slider can partially offset the gravity of the slider and the tensioning wheel, so that the system reaches a dynamic balance. This state of balance allows external operators to change the tension of the traction rope by adjusting the weight of the first counterweight block, thereby flexibly adjusting the tension applied by the first tensioning wheel to the material belt. This adjustability enables the equipment to adapt to different operating conditions and material belt characteristics, ensuring that the appropriate tension of the material belt can be maintained in various situations, and improving the operating accuracy and adaptability of the equipment. In addition, by adjusting the first counterweight block, the system can respond and adjust quickly, reducing adjustment time and complexity, and improving production efficiency and reliability.

[0019] In some embodiments, the material belt tensioning mechanism further includes two first limiters respectively arranged at both ends of the first slide rail, and the first limiters are used to abut against the first slider to limit the sliding stroke of the first slider. The material belt tensioning mechanism further enhances the control of the sliding stroke of the first slider by adding two first limiters respectively arranged at both ends of the first slide rail. The main function of the first limiter is to abut against the first slider to limit its sliding range on the first slide rail. This design helps to prevent the first slider from exceeding the predetermined range of motion and ensure that the material belt tensioning mechanism operates within a safe and effective operating range. By setting the first limiter, the system can avoid potential mechanical damage or uncontrolled material belt tension caused by excessive sliding of the first slider. This not only improves the safety and reliability of the equipment, but also reduces the maintenance requirements caused by excessive wear or accidental collision. In addition, the design of the first limiter can also be adjusted according to specific application requirements to adapt to different material belt specifications and tension requirements, thereby enhancing the flexibility and adaptability of the system.

[0020] In some embodiments, the material belt tensioning mechanism further includes a first photoelectric component provided on the frame, the first photoelectric component is provided on the frame and is not lower than the first tensioning wheel in the height direction, and the first photoelectric component is used to detect the position of the first slider on the first slide rail to determine the height position of the first tensioning wheel. The material belt tensioning mechanism further improves the monitoring and control capabilities of the position of the first slider by introducing the first photoelectric component. The first photoelectric component is installed on the frame, and its position is not lower than the first tensioning wheel in the height direction. It can detect the specific position of the first slider on the first slide rail in real time, so as to determine the height position of the first tensioning wheel. By using the first photoelectric component, the system can accurately monitor the position change of the first slider, which is crucial to maintaining the appropriate tension of the material belt. The first photoelectric component can send a signal when the first slider reaches a predetermined position, prompting the operator or the automatic control system to make necessary adjustments. This real-time monitoring capability helps to improve the automation and response speed of the system, ensuring that the optimal tensioning state can be maintained under various operating conditions.

[0021] In some embodiments, the material belt tensioning mechanism further includes a sensor assembly and a reflector plate provided on the frame, the sensor assembly and the reflector plate are respectively provided on opposite sides of the first slide rail, the material belt can pass between the sensor assembly and the reflector plate, the sensor assembly is used to emit light to the reflector plate, and the reflector plate is used to reflect the light to the sensor assembly, so as to determine whether the material belt passes between the sensor assembly and the reflector plate by whether the light is blocked by the material belt. The material belt tensioning mechanism realizes effective monitoring of the material belt position by introducing the sensor assembly and the reflector plate. The sensor assembly and the reflector plate are respectively installed on opposite sides of the first slide rail to form an optical path detection system. The material belt can pass between the sensor assembly and the reflector plate, the sensor assembly will emit light to the reflector plate, and the reflector plate is responsible for reflecting the light back to the sensor assembly. The core function of this design is to determine whether the material belt passes normally between the sensor assembly and the reflector plate by detecting whether the light is blocked by the material belt. When the material strip blocks the light, the sensor component detects the interruption of light and determines the position and status of the material strip. This information can be used to monitor the operation of the material strip in real time to ensure that the material strip moves on the correct track. The advantage of this system is that its non-contact detection method reduces physical interference with the material strip while providing high-precision and high-reliability monitoring capabilities. Through this photoelectric detection method, the system can quickly respond to abnormal conditions of the material strip, such as deviation from the track or breakage, thereby improving the safety and efficiency of the production line. In addition, this design is highly flexible and can be adjusted according to different material strip widths and materials.

[0022] In some embodiments, the number of the material strip tensioning mechanisms is set to be multiple and corresponds one-to-one with the material strip guiding mechanisms.

[0023] In some embodiments, the protective film guide mechanism is arranged below the discharge tray, and the protective film guide mechanism includes a second slide rail, a second slider, a second tensioning wheel and a plurality of transfer rollers arranged vertically on the frame, the second slider is slidably arranged on the second slide rail, the second tensioning wheel is rotatably arranged on the second slider, the protective film is connected to the receiving tray after passing through the second tensioning wheel and a plurality of transfer rollers, the side of the second tensioning wheel facing away from the discharge tray is used for the protective film to abut against and be wound, and the second slider and the second tensioning wheel can have a tendency to slide downward along the second slide rail under the action of gravity to tension the protective film. The second slider can slide on the second slide rail, allowing the system to automatically adjust the position as needed. The second tensioning wheel is rotatably mounted on the second slider to adjust the tension of the protective film. After passing through the second tensioning wheel and a plurality of transfer rollers, the protective film is finally connected to the receiving tray. Such a path design ensures that the protective film remains stable and controlled during the entire transmission process. It is particularly noteworthy that the side of the second tensioning wheel facing away from the discharge tray is specially designed for the abutment and winding of the protective film. The second slider and the second tensioning wheel have a tendency to slide down along the second slide rail under the action of gravity. This design uses gravity to naturally provide continuous tension for the protective film. In this way, the protective film can be firmly maintained on the predetermined path, reducing the possibility of deviation and wrinkles, and no additional power device is required, thereby simplifying the structure and reducing energy consumption. This automated tensioning mechanism not only improves the stability of the protective film transmission, but also reduces the need for manual adjustment and improves production efficiency.

[0024] In some embodiments, the protective film guide mechanism further includes a second pulley, a second traction rope and a second counterweight, the second pulley is arranged on the frame and is not lower than the second tensioning wheel in the height direction, the second traction rope is wound around and abuts against the side of the second pulley facing away from the ground, one end of the second traction rope is fixed to the second slider, and the other end of the second traction rope is connected to the second counterweight, the pulling force of the second traction rope on the second slider can offset part of the gravity of the second slider and the second tensioning wheel and achieve balance, and the weight of the second counterweight is set to be able to change under external operation to adjust the pulling force of the second traction rope on the second slider, thereby adjusting the tension of the second tensioning wheel on the protective film. The protective film guide mechanism adds a second pulley, a second traction rope and a second counterweight to achieve more precise tension control. The combination of these components provides a dynamic balancing mechanism that can adjust the tension of the protective film according to actual needs. The working principle of the system is to use the second traction rope to apply tension to the second slider to offset part of the gravity generated by the second slider and the second tensioning wheel. This tension allows the tension of the protective film to be accurately controlled and adjusted. Of particular importance is that the weight of the second counterweight is adjustable. This feature allows the user to change the weight of the counterweight under external operation, thereby adjusting the tension applied by the second traction rope to the second slider. By changing the weight of the counterweight, the user can flexibly adjust the tension of the second tensioning wheel on the protective film to meet the needs of different materials or process conditions. This design provides a simple and effective way to control the tension of the protective film, ensuring the stability and consistency of the protective film during transmission, which not only improves the flexibility of operation, but also enhances the ability to control production quality.

[0025] In some embodiments, the protective film guiding mechanism further includes two second limiters respectively arranged at both ends of the second slide rail, and the second limiters are used to abut against the second slider to limit the sliding stroke of the second slider. In order to further enhance the stability and safety of the protective film guiding mechanism, the system adds two second limiters respectively arranged at both ends of the second slide rail. The main function of these limiters is to limit the sliding stroke of the second slider. Specifically, the second limiter prevents the slider from sliding beyond a predetermined range by physical contact with the second slider. This design not only protects the equipment from mechanical damage that may be caused by excessive sliding, but also ensures that the protective film remains on the correct path during transmission, preventing uneven film tension or film offset problems caused by slider position offset. By setting these limiters, the system can provide a reliable stopping mechanism when the slider reaches the stroke limit, thereby avoiding potential operational errors or unexpected situations. This mechanical limiting method is simple and effective, and can achieve precise management of slider movement without the need for complex electronic control.

[0026] In some embodiments, the protective film guide mechanism further includes a second photoelectric component provided on the frame, the second photoelectric component is provided on the frame and is not lower than the second tensioning wheel in the height direction, and the second photoelectric component is used to detect the position of the second slider on the second slide rail to determine the height position of the second tensioning wheel. Through photoelectric sensing technology, the second photoelectric component can monitor the position change of the second slider in real time. This monitoring is crucial for determining the height position of the second tensioning wheel, because the position of the slider directly affects the height of the tensioning wheel and the corresponding film tensioning force. The advantages of this detection method are its non-contact and high precision. The photoelectric component can quickly and accurately obtain the position data of the slider and transmit this information to the control system. With these data, the system can dynamically adjust the operating parameters to maintain the optimal tension state of the protective film. In addition, the introduction of the second photoelectric component can also be used in the automation control process, for example, when the slider position is detected to deviate from the preset range, an alarm or automatic adjustment mechanism is triggered. This not only improves the intelligence of the system, but also enhances the safety and reliability of operation.

[0027] In some embodiments, the automatic unwinding and rewinding device further comprises a driving device arranged on the frame, and the driving device comprises a support, a motor seat, a motor, a coupling, a locking nut, a washer, a bearing, a bearing seat, a rotating shaft, a flat key and a locking sleeve.

The bearing is arranged on the bearing seat, and the bearing is sleeved on the rotating shaft, which can be locked on the rotating shaft by the locking nut and the washer. The flat key is embedded in the keyway of the rotating shaft and is used to clamp the discharge tray or the receiving tray to prevent the discharge tray or the receiving tray from slipping relative to the rotating shaft. The locking sleeve can be sleeved and fixed on the rotating shaft and fix the discharge tray or the receiving tray on the rotating shaft to prevent the discharge tray or the receiving tray from slipping along the axial direction of the rotating shaft.

The protective film 920 can be guided by the protective film guide mechanism 500 and re-stacked and wound on the receiving tray 300 together with the material tape 910, that is, the protective film 920 can be recycled. Through the unique guiding design, the automatic unwinding and rewinding device 10 can efficiently separate and recycle the material tape 910 and the protective film 920.

At the same time, the device can replace the material belt 910 and the protective film 920 without stopping the machine, further improving production efficiency.

The guide seat 430 can slide along the guide rail 420 and drive the first guide wheel 442 to approach or move away from the first guide wheel 441. The first guide wheel 442 can move to a first position and a second position under the drive of the guide seat 430. In the first position, the material belt 910 is clamped between the outer peripheral surface of the first guide wheel 441 and the outer peripheral surface of the first guide wheel 442. In the second position, the outer peripheral surface of the first guide wheel 441 and the outer peripheral surface of the first guide wheel 442 are arranged at intervals, so that the material belt 910 can be taken and placed between the outer peripheral surface of the first guide wheel 441 and the outer peripheral surface of the first guide wheel 442. In this embodiment, two material belt guide mechanisms 400 are arranged, one of which is used to guide the material belt 910 released from the material discharge tray 200, and the other is used to guide the material belt 910 to the material receiving tray 300. This design realizes more accurate and flexible guiding and control of the material belt 910 by setting a fixed plate 410, a guide rail 420, a guide seat 430, a first guide wheel 441 and a first guide wheel 442 in each material belt guiding mechanism 400. The first guide wheel 441 is rotatably arranged on the fixed plate 410, and the guide seat 430 is slidably arranged on the guide rail 420, and drives the first guide wheel 442 to approach or move away from the first guide wheel 441. The guide seat 430 can slide along the guide rail 420, so that the first guide wheel 442 can move to the first position and the second position under the drive of the guide seat 430. In the first position, the material belt 910 is clamped between the outer peripheral surfaces of the first guide wheel 441 and the first guide wheel 442, ensuring the stable transmission and precise positioning of the material belt 910. In the second position, the outer peripheral surfaces of the first guide wheel 441 and the first guide wheel 442 are arranged at intervals, providing a convenient space for taking and placing the material belt 910. This design not only improves the stability and accuracy of the material belt 910 during transmission, but also simplifies the loading and unloading operations of the material belt 910, thereby improving the operating efficiency and flexibility of the overall equipment.

[0045] More specifically, if Figure 6 As shown, in some embodiments, the material belt guide mechanism 400 further includes an elastic member 450, one end of which is fixed to the fixed plate 410, and the other end of which is fixed to the guide seat 430, and the elastic member 450 is used to provide a pulling force to make the guide seat 430 slide in the direction close to the first guide wheel 441. One end of the elastic member 450 is fixed to the fixed plate 410, and the other end is fixed to the guide seat 430, providing a continuous pulling mechanism. This pulling force causes the guide seat 430 to slide naturally in the direction close to the first guide wheel 441. This design ensures that during the transmission of the material belt 910, the guide seat 430 is always maintained in a position that is conducive to the stable transmission of the material belt 910, and the material belt 910 can always be maintained between the first guide wheel 441 and the first guide wheel 442 during the transmission process, thereby reducing the potential error caused by the relaxation or deviation of the material belt 910. In addition, the use of the elastic member 450 can also absorb and alleviate the vibration or impact that may occur during the transmission process, thereby improving the durability and reliability of the entire system. This not only improves the accuracy and stability of the material belt 910 guidance, but also simplifies the adjustment and maintenance process of the equipment, making the operation more efficient and convenient.

[0046] More specifically, if Figure 6 As shown, in some embodiments, the material belt guiding mechanism 400 also includes an operating member 460 disposed on the guide seat 430, and the operating member 460 is used for operation to drive the guide seat 430 to slide on the guide rail 420. By arranging the operating member 460 on the guide seat, convenient control of the guide seat 430 sliding on the guide rail 420 is achieved. The operating member 460 is installed on the guide seat 430 and is designed to manually or automatically adjust the position of the guide seat 430. By operating the operating member 460, the user can easily adjust the position of the guide seat 430 on the guide rail 420 and adjust the distance between the first guide wheel 441 and the second guide wheel 442. This design is particularly suitable for production environments that require frequent replacement of material belts or adjustment of material belt paths. By simplifying the operating process, the adjustment time is reduced and the production efficiency is improved.

[0047] See also Figure 4 , Figure 5 and Figure 7In some embodiments, the automatic unwinding and rewinding device 10 also includes a material belt tensioning mechanism 600 arranged on the frame 100 and located below the material belt guiding mechanism 400, and the material belt tensioning mechanism 600 includes a first slide rail 611, a first slider 612, and a first tensioning wheel 613. The first slide rail 611 is vertically arranged on the frame 100, the first slider 612 is slidably arranged on the first slide rail 611, and the first tensioning wheel 613 is rotatably arranged on the first slider 612. The side of the first tensioning wheel 613 facing away from the material belt guiding mechanism 400 is used for the material belt 910 to abut and be wound around, and the first slider 612 and the first tensioning wheel 613 can have a tendency to slide downward along the first slide rail 611 under the action of gravity to tension the material belt 910. The material belt tensioning mechanism 600 includes a first slide rail 611 vertically arranged on the frame 100, a first slider 612 slidably arranged on the slide rail, and a first tensioning wheel 613 rotatably arranged on the slider. The first tensioning wheel 613 is designed so that the side of the first tensioning wheel 613 facing away from the material belt guide mechanism 400 can be provided for the material belt 910 to abut and be wound, thereby providing the necessary tensioning force during the transmission of the material belt 910. Since the first slider 612 and the first tensioning wheel 613 have a tendency to slide downward along the first slide rail 611 under the action of gravity, this natural gravity-driven mechanism effectively provides continuous tensioning force for the material belt 910, ensuring the stability and consistency of the material belt 910 during the transmission process. Through this design, the tension of the material belt 910 can be automatically adjusted, reducing the need for human intervention, and improving the automation and operation efficiency of the system. At the same time, this design also helps to prevent the material belt 910 from loosening or slipping, extending the service life of the equipment and reducing maintenance costs.

[0048] Specifically, Figure 4 , Figure 5 and Figure 7As shown, in some embodiments, the material belt tensioning mechanism 600 also includes a first pulley 614, a first traction rope 615 and a first counterweight 616, the first pulley 614 is arranged on the frame 100 and is not lower than the first tensioning wheel 613 in the height direction, the first traction rope 615 is wound around and abuts against the side of the first pulley 614 facing away from the ground, one end of the first traction rope 615 is fixed to the first slider 612, and the other end of the first traction rope 615 is connected to the first counterweight 616, the pulling force of the first traction rope 615 on the first slider 612 can offset part of the gravity of the first slider 612 and the first tensioning wheel 613 and achieve balance, and the weight of the first counterweight 616 is set to be able to change under external operation to adjust the pulling force of the first traction rope 615 on the first slider 612, thereby adjusting the tensioning force of the first tensioning wheel 613 on the material belt 910. The material belt tensioning mechanism 600 further enhances the precise control and flexible adjustment of the tension of the material belt 910 by introducing the first pulley 614, the first traction rope 615 and the first counterweight 616. The first pulley 614 is arranged on the frame 100, and its position is higher than or equal to the first tensioning wheel 613 in the height direction to ensure that the traction rope can be smoothly wound and provide appropriate tension. One end of the first traction rope 615 is fixed on the first slider 612, and the other end is connected to the first counterweight 616. The traction rope passes through the side of the pulley facing away from the ground, and the mechanical advantage of the pulley is used to change the traction direction. Through this design, the tension applied by the first traction rope 615 on the first slider 612 can partially offset the gravity of the slider and the tensioning wheel, so that the system reaches a dynamic balance. This equilibrium state allows an external operator to change the tension of the traction rope by adjusting the weight of the first counterweight 616, thereby flexibly adjusting the tension applied by the first tensioning wheel 613 to the material belt 910. This adjustability enables the device to adapt to different operating conditions and characteristics of the material strip 910, ensuring that the appropriate tension of the material strip 910 can be maintained under various conditions, thereby improving the operating accuracy and adaptability of the device. In addition, by adjusting the first counterweight 616, the system can respond and adjust quickly, reducing adjustment time and complexity, and improving production efficiency and reliability.

[0049] More specifically, if Figure 4 , Figure 5 and Figure 7As shown, in some embodiments, the strip tensioning mechanism 600 further includes two first limiters 617 respectively disposed at both ends of the first slide rail 611, and the first limiters 617 are used to abut against the first slider 612 to limit the sliding stroke of the first slider 612. The strip tensioning mechanism 600 further enhances the control of the sliding stroke of the first slider 612 by adding two first limiters 617 respectively disposed at both ends of the first slide rail 611. The main function of the first limiter 617 is to abut against the first slider 612 to limit its sliding range on the first slide rail 611. This design helps prevent the first slider 612 from exceeding the predetermined range of motion and ensures that the strip tensioning mechanism 600 operates within a safe and effective operating range. By providing the first limiter 617, the system can avoid potential mechanical damage or uncontrolled tension of the strip 910 caused by excessive sliding of the first slider 612. This not only improves the safety and reliability of the equipment, but also reduces the maintenance requirements caused by excessive wear or accidental collision. In addition, the design of the first limiter 617 can be adjusted according to specific application requirements to adapt to different material strip 910 specifications and tension requirements, thereby enhancing the flexibility and adaptability of the system.

[0050] More specifically, if Figure 4 , Figure 5 and Figure 7 As shown, in some embodiments, the material belt tensioning mechanism 600 further includes a first photoelectric component 710 disposed on the frame 100, the first photoelectric component 710 is disposed on the frame 100 and is not lower than the first tensioning wheel 613 in the height direction, and the first photoelectric component 710 is used to detect the position of the first slider 612 on the first slide rail 611 to determine the height position of the first tensioning wheel 613. The material belt tensioning mechanism 600 further improves the monitoring and control capabilities of the position of the first slider 612 by introducing the first photoelectric component 710. The first photoelectric component 710 is installed on the frame 100, and its position is not lower than the first tensioning wheel 613 in the height direction. It can detect the specific position of the first slider 612 on the first slide rail 611 in real time, so as to determine the height position of the first tensioning wheel 613. By using the first photoelectric component 710, the system can accurately monitor the position change of the first slider 612, which is essential for maintaining the appropriate tension of the material belt 910. The first photoelectric component 710 can send a signal when the first slider 612 reaches a predetermined position, prompting the operator or the automatic control system to make necessary adjustments. This real-time monitoring capability helps to improve the automation and response speed of the system, ensuring that the optimal tensioning state can be maintained under various operating conditions.

[0051] More specifically, if Figure 4 , Figure 5 and Figure 7As shown, in some embodiments, the material belt tensioning mechanism 600 further includes a sensor assembly 618 and a reflector 619 disposed on the frame 100, the sensor assembly 618 and the reflector 619 are respectively disposed on opposite sides of the first slide rail 611, the material belt 910 can pass between the sensor assembly 618 and the reflector 619, the sensor assembly 618 is used to emit light to the reflector 619, and the reflector 619 is used to reflect the light to the sensor assembly 618, so as to determine whether the material belt 910 passes between the sensor assembly 618 and the reflector 619 by whether the light is blocked by the material belt 910. The material belt tensioning mechanism 600 effectively monitors the position of the material belt 910 by introducing the sensor assembly 618 and the reflector 619. The sensor assembly 618 and the reflector 619 are respectively mounted on opposite sides of the first slide rail 611 to form an optical path detection system. The material strip 910 can pass between the sensor assembly 618 and the reflector 619. The sensor assembly 618 will emit light to the reflector 619, and the reflector 619 is responsible for reflecting the light back to the sensor assembly 618. The core function of this design is to determine whether the material strip 910 passes between the sensor assembly 618 and the reflector 619 normally by detecting whether the light is blocked by the material strip 910. When the material strip 910 blocks the light, the sensor assembly 618 will detect the interruption of the light and thus determine the position and state of the material strip 910. This information can be used to monitor the operation of the material strip 910 in real time to ensure that the material strip 910 moves on the correct track. The advantage of this system is that its non-contact detection method reduces physical interference with the material strip 910, while providing high-precision and high-reliability monitoring capabilities. Through this photoelectric detection method, the system can quickly respond to abnormal conditions of the material strip 910, such as deviation from the track or breakage, thereby improving the safety and efficiency of the production line. In addition, this design is highly flexible and can be adjusted according to different widths and materials of the strip 910 .

[0052] More specifically, if Figure 4 and Figure 5 As shown, in some embodiments, the number of the material strip tensioning mechanisms 600 is set to be multiple and corresponds one-to-one with the material strip guiding mechanisms 400 .

[0053] See also Figure 2 and Figure 8In some embodiments, the protective film guide mechanism 500 is disposed below the discharge tray 200, and the protective film guide mechanism 500 includes a second slide rail 521, a second slider 522, a second tensioning wheel 523 and a plurality of transfer rollers 510 vertically disposed on the frame 100, the second slider 522 is slidably disposed on the second slide rail 521, the second tensioning wheel 523 is rotatably disposed on the second slider 522, the protective film 920 is wound around the second tensioning wheel 523 and the plurality of transfer rollers 510 before being connected to the receiving tray 300, the side of the second tensioning wheel 523 facing away from the discharge tray 200 is used for the protective film 920 to abut against and be wound around, the second slider 522 and the second tensioning wheel 523 can have a tendency to slide downward along the second slide rail 521 under the action of gravity to tension the protective film 920. The second slider 522 can slide on the second slide rail 521, allowing the system to automatically adjust the position as needed. The second tensioning wheel 523 is rotatably mounted on the second slider 522 to adjust the tension of the protective film 920. After passing through the second tensioning wheel 523 and a plurality of transfer rollers 510, the protective film 920 is finally connected to the receiving tray 300. Such a path design ensures that the protective film 920 remains stable and controlled during the entire transmission process. It is particularly noteworthy that the side of the second tensioning wheel 523 facing away from the discharge tray 200 is specially designed for the abutment and winding of the protective film 920, and the second slider 522 and the second tensioning wheel 523 have a tendency to slide downward along the second slide rail 521 under the action of gravity. This design uses gravity to naturally provide continuous tension for the protective film 920. In this way, the protective film 920 can be firmly maintained on the predetermined path, reducing the possibility of deviation and wrinkles, and no additional power device is required, thereby simplifying the structure and reducing energy consumption. This automated tensioning mechanism not only improves the stability of the transmission of the protective film 920, but also reduces the need for manual adjustment and improves production efficiency.

[0054] Specifically, Figure 8As shown, in some embodiments, the protective film guiding mechanism 500 also includes a second pulley 524, a second traction rope 525 and a second counterweight 526, the second pulley 524 is arranged on the frame 100 and is not lower than the second tensioning wheel 523 in the height direction, the second traction rope 525 is wound around and abuts against the side of the second pulley 524 facing away from the ground, one end of the second traction rope 525 is fixed to the second slider 522, and the other end of the second traction rope 525 is connected to the second counterweight 526, the pulling force of the second traction rope 525 on the second slider 522 can offset part of the gravity of the second slider 522 and the second tensioning wheel 523 and achieve balance, and the weight of the second counterweight 526 is set to be able to change under external operation to adjust the pulling force of the second traction rope 525 on the second slider 522, thereby adjusting the tensioning force of the second tensioning wheel 523 on the protective film 920. The protective film guide mechanism 500 adds a second pulley 524, a second traction rope 525, and a second counterweight 526 to achieve more precise tension control. The combination of these components provides a dynamic balancing mechanism that can adjust the tension of the protective film 920 according to actual needs. The working principle of the system is to use the second traction rope 525 to apply tension to the second slider 522 to offset part of the gravity generated by the second slider 522 and the second tensioning wheel 523. This tension allows the tension of the protective film 920 to be accurately controlled and adjusted. It is particularly important that the weight of the second counterweight 526 is adjustable. This feature allows the user to change the weight of the counterweight under external operation, thereby adjusting the tension applied by the second traction rope 525 to the second slider 522. By changing the weight of the counterweight, the user can flexibly adjust the tension of the second tensioning wheel 523 on the protective film 920 to meet the needs of different materials or process conditions. This design provides a simple and effective method to control the tension of the protective film 920, ensuring the stability and consistency of the protective film 920 during the transmission process, which not only improves the flexibility of operation but also enhances the control ability of production quality.

[0055] More specifically, if Figure 8As shown, in some embodiments, the protective film guide mechanism 500 also includes two second limiters 527 respectively arranged at both ends of the second slide rail 521, and the second limiters 527 are used to abut against the second slider 522 to limit the sliding stroke of the second slider 522. In order to further enhance the stability and safety of the protective film guide mechanism 500, the system adds two second limiters 527 respectively arranged at both ends of the second slide rail 521. The main function of these limiters is to limit the sliding stroke of the second slider 522. Specifically, the second limiter 527 prevents the slider from sliding beyond a predetermined range by physical contact with the second slider 522. This design can not only protect the device from mechanical damage that may be caused by excessive sliding, but also ensure that the protective film 920 remains on the correct path during transmission, preventing uneven film tension or film offset problems caused by the offset of the slider position. By setting these limiters, the system can provide a reliable stopping mechanism when the slider reaches the stroke limit, thereby avoiding potential operating errors or unexpected situations. This mechanical limit method is simple and effective, and can achieve precise management of the slider movement without the need for complex electronic control.

[0056] More specifically, if Figure 8 As shown, in some embodiments, the protective film guide mechanism 500 further includes a second photoelectric component 720 disposed on the frame 100, the second photoelectric component 720 is disposed on the frame 100 and is not lower than the second tensioning wheel 523 in the height direction, and the second photoelectric component 720 is used to detect the position of the second slider 522 on the second slide rail 521 to determine the height position of the second tensioning wheel 523. Through photoelectric sensing technology, the second photoelectric component 720 can monitor the position change of the second slider 522 in real time. This monitoring is crucial for determining the height position of the second tensioning wheel 523, because the position of the slider directly affects the height of the tensioning wheel and the corresponding film tensioning force. The advantages of this detection method are its non-contact and high precision. The photoelectric component can quickly and accurately obtain the position data of the slider and transmit this information to the control system. Through these data, the system can dynamically adjust the operating parameters to maintain the optimal tension state of the protective film 920. In addition, the introduction of the second photoelectric component 720 can also be used in an automated control process, for example, when the slider position is detected to deviate from a preset range, an alarm or automatic adjustment mechanism is triggered. This not only improves the intelligence of the system, but also enhances the safety and reliability of operation.

The flat key 891 is embedded in the keyway of the rotating shaft 890 and is used to clamp the discharge tray 200 or the receiving tray 300 to prevent the discharge tray 200 or the receiving tray 300 from rotating and slipping relative to the rotating shaft 890. The locking sleeve 892 can be sleeved and fixed on the rotating shaft 890 and fix the discharge tray 200 or the receiving tray 300 on the rotating shaft 890 to prevent the discharge tray 200 or the receiving tray 300 from slipping along the axial direction of the rotating shaft 890.
