[0025] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0026] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0027] The following is a detailed description of a tape winding device according to an embodiment of this application, with reference to the accompanying drawings.

[0028] like Figures 1 to 7 As shown, the material strip winding device according to an embodiment of this application includes: a base 10 and a feeding device 20, a conveying device 30 and a pressing device 40 disposed on the base 10.

[0029] Specifically, the feeding device 20 includes a support unit 21 for supporting and positioning the workpiece, an unwinding unit 22 for providing the material strip, a clutch unit 23 for controlling the initial end of the material strip to adhere to the workpiece, and a cutting unit 24 for cutting the material strip connected to the workpiece; the pressing device 40 is used to press the workpiece against the support unit 21, and at least one of the pressing device 40 and the support unit 21 drives the workpiece to rotate so as to wind the material strip around the workpiece; the conveying device 30 is used to convey the workpiece to the support unit 21 or to remove the workpiece from the support unit 21.

[0030] In some embodiments, such as Figures 1 to 7 As shown, the tape winding device according to an embodiment of this application is mainly used for winding tape for lenses. The tape winding device mainly includes a base 10, with a feeding device 20, a conveying device 30, and a pressing device 40 mounted on the upper side of the base 10. The feeding device 20, conveying device 30, and pressing device 40 are sequentially distributed along a first direction, which can be the length direction of the base 10. The feeding device 20 includes a supporting unit 21, an unwinding unit 22, a clutch unit 23, and a cutting unit 24. The supporting unit 21 is used to support and position the workpiece (e.g., a lens); the pressing device 40 can press and fix the workpiece onto the supporting unit 21 and, in cooperation with the supporting unit 21, can drive the workpiece to rotate around its own axis. The unwinding unit 22 is located on the side of the supporting unit 21 away from the pressing device 40, and it can provide tape for winding the workpiece; the clutch unit 23 is located between the unwinding unit 22 and the supporting unit 21, and can control the starting end of the tape to adhere to the outer peripheral surface of the workpiece. When the strip is applied to the outer circumference of the workpiece, the strip is wound around the workpiece as the workpiece rotates under the combined drive of the pressing device 40 and the support unit 21. The cutting unit 24 is located beside the support unit 21. After the workpiece has finished wrapping the strip, the cutting unit 24 can cut the strip connected to the workpiece.

[0031] When the tape winding device according to the embodiment of this application is in use, firstly, the conveying device 30 conveys the workpiece to be wound to the carrying unit 21; then, the pressing device 40 presses and fixes the workpiece to the carrying unit 21; then, the clutch unit 23 attaches the starting end of the tape (i.e., adhesive tape) to the outer circumferential surface of the workpiece; then, under the action of the carrying unit 21 and the pressing device 40, the workpiece is driven to rotate around its axis, and the tape is wound onto the workpiece as the workpiece rotates; after winding is completed, the cutting unit 24 cuts the tape between the clutch unit 23 and the workpiece; then, the conveying device 30 removes the wound workpiece from the carrying unit 21, and the next recycling operation can be carried out.

[0032] Therefore, the material strip winding equipment provided in this embodiment can realize the automated operation of the workpiece material strip winding process through the coordinated action of the feeding device 20, the conveying device 30 and the pressing device 40, which significantly improves production efficiency. At the same time, the fully automated process greatly reduces human intervention, effectively reduces the risk of contamination by dust, fingerprints and other impurities, improves the cleanliness and reliability of optical lenses, and eliminates individual differences caused by manual operation, ensuring a high degree of consistency in the winding effect of each workpiece.

[0033] In some specific embodiments of this application, the pressing device 40 includes: a first moving component 41 disposed on the base 10; a pressing component 42 provided with a pressing member 421, the pressing member 421 being configured to be rotatable; the pressing component 42 is disposed on the first moving component 41, the first moving component 41 being used to drive the pressing component 42 to move between a first position and a second position; in the first position, the pressing component 42 is offset from the support unit 21 in the vertical direction; in the second position, the pressing member 421 is directly opposite the support unit 21, and the pressing component 42 can drive the pressing member 421 to move downward to press the workpiece against the support unit 21.

[0034] Specifically, such as Figure 6 As shown, the pressing device 40 includes a first moving component 41 and a pressing component 42. The first moving component 41 can be a pneumatic slide, and its base is fixedly connected to the base 10. The pressing component 42 includes a pressing drive (e.g., a pneumatic slide), a mounting base, and a pressing component 421. The pressing drive is vertically arranged, its base is fixed to the slider of the first moving component 41, the mounting base is fixed to the slider of the pressing drive, and the pressing component 421 is rotatably connected to the lower side of the mounting base.

[0035] The first moving component 41 drives the pressing component 42 to move along a first direction between a first position and a second position. The first position can be a clearance position, and the second position can be a mating position. When the pressing component 42 is in the first position, the pressing component 42 is offset from the bearing unit 21 in the vertical direction; when the pressing component 42 is in the second position, the pressing member 421 is directly facing the bearing unit 21 and its rotation axis is coaxial with the workpiece axis. At this time, the pressing drive component drives the pressing member 421 to move downward, thereby pressing the workpiece tightly against the bearing unit 21.

[0036] In this embodiment, the first moving component 41 drives the pressing component 42 to move between the first position and the second position, thereby achieving effective avoidance of the pressing component 42, which facilitates the workpiece loading or unloading operation of the conveying device 30.

[0037] According to one embodiment of this application, the feeding device 20 includes: a connecting seat 25 disposed on the base 10, the bearing unit 21 and the cutting unit 24 disposed on the connecting seat 25; a movable seat 26 movably disposed on the connecting seat 25 between a third position and a fourth position, the unwinding unit 22 and the clutch unit 23 disposed on the movable seat 26; a first driving member disposed on the connecting seat 25, the output end of the first driving member being connected to the movable seat 26; in the third position, the clutch unit 23 allows the material strip to adhere to the workpiece on the bearing unit 21; in the fourth position, the clutch unit 23 allows the material strip at the corresponding position to be spaced apart from the workpiece on the bearing unit 21.

[0038] In other words, such as Figure 3 and Figure 4 As shown, the feeding device 20 also includes a connecting seat 25, a movable seat 26, and a first driving member. The connecting seat 25 is located on the upper side of the base 10, and the movable seat 26 is movably located on the upper side of the connecting seat 25 in a first direction via a guide rail slider structure. The first driving member (e.g., a cylinder) is fixedly connected to the connecting seat 25, and its output end is fixedly connected to the movable seat 26, thereby driving the movable seat 26 to move between a third position and a fourth position in the first direction. When the movable seat 26 is in the third position, the clutch unit 23 applies the material strip to the outer peripheral surface of the workpiece carried by the carrying unit 21; when the movable seat 26 is in the fourth position, the clutch unit 23 separates the material strip at the corresponding position from the workpiece carried by the carrying unit 21.

[0039] In this embodiment, the working state of the clutch unit 23 can be switched by controlling the moving seat 26 to move between the third and fourth positions. At the same time, since the unwinding unit 22 and the clutch unit 23 are integrated into the moving seat 26, the tension of the material strip can remain stable during the switching of the working state of the clutch unit 23, avoiding slack or stretching deformation, and there is no need to set up a complex tension control structure.

[0040] In some specific embodiments of this application, the unwinding unit 22 includes: a rotating shaft 221, which is rotatably disposed on the movable seat 26 about its axis; an unwinding reel 222, which is disposed on the rotating shaft 221 and is used to mount the strip material; and a detection element 223, which is disposed on the movable seat 26 and is used to detect the rotation state of the unwinding reel 222.

[0041] In other words, such as Figure 3As shown, the unwinding unit 22 mainly includes a rotating shaft 221, an unwinding reel 222, and a detection element 223. The rotating shaft 221 can be a damping shaft, rotatably mounted on the upper side of the movable seat 26 around its axis. The unwinding reel 222 includes a first reel body and a second reel body. The first reel body is fixedly connected to the rotating shaft 221, and its upper side is provided with multiple tensioning blocks distributed circumferentially. These tensioning blocks can elastically float radially along the first reel body, thereby abutting against the inner wall surface of the center hole of the strip roll to fix the strip roll. The second reel body is coaxially sleeved on the rotating shaft 221 and detachably connected (e.g., fastened with screws). The second reel body is located above and spaced apart from the first reel body, and by cooperating with the first reel body, it can restrict the axial position of the strip roll.

[0042] The detection element 223 can be a photoelectric sensor, and the unwinding reel 222 has a detection hole corresponding to the photoelectric sensor. The rotation state of the unwinding reel 222 can be detected by the photoelectric sensor. Since the rotation of the unwinding reel 222 is passively driven by the traction force generated when the workpiece winds the strip, when the strip breaks abnormally or runs out, the traction force is interrupted, and the unwinding reel 222 will stop rotating. Therefore, by detecting the state of the unwinding reel 222, it is possible to determine whether the strip is abnormal, thus facilitating rapid fault identification and corresponding measures.

[0043] like Figure 3 As shown in some optional examples of this application, the unwinding unit 22 is also equipped with a damping adjustment assembly 224 for adjusting the rotational damping of the rotating shaft 221. The damping adjustment assembly 224 includes a stud, a spring, and a damping block arranged radially along the rotating shaft 221. The damping block is movably embedded in the movable seat 26 and in radial contact with the rotating shaft 221. The stud is threadedly connected to the movable seat 26, and the spring abuts against the stud and the damping block. By turning the stud, its preload on the spring can be adjusted, thereby changing the pressure exerted by the damping block on the rotating shaft 221, achieving stepless adjustment of the rotational damping. This structure can adjust the damping of the rotating shaft 221 to a reasonable range according to actual working conditions, ensuring that the unwound strip maintains appropriate tension while avoiding excessive tension that could cause strip deformation or breakage.

[0044] In some specific embodiments of this application, the feeding device 20 further includes a pressing unit 27, which is disposed on the connecting seat 25 and is configured to press the material strip tightly against the surface of the workpiece when the workpiece is wound with the material strip.

[0045] Specifically, such as Figure 3 and Figure 4As shown, the feeding device 20 is equipped with a pressing unit 27, which is located beside the bearing unit 21 and above the connecting seat 25. During the workpiece rotation and winding process, the pressing unit 27 can continuously press the material strip tightly against the workpiece surface to avoid gaps between the material strip and the workpiece, ensuring the sealing and stability of the winding. After the material strip is cut, the workpiece is driven to continue rotating, and the pressing unit 27 presses the end of the material strip tightly against the workpiece surface, making the tail end flat and fixed, thereby effectively preventing the tail end from lifting and causing the entire material strip to loosen, ensuring the long-term stability and reliability of the wound material strip.

[0046] According to one embodiment of this application, the pressing unit 27 includes: a second moving component disposed on the connecting seat 25, and having a first movable seat 271 movable between a fifth position and a sixth position; a first swing arm 272 rotatably disposed on the first movable seat 271; a first pressing wheel 273 and a first elastic element 274, the first pressing wheel 273 rotatably disposed on the first swing arm 272, and the first elastic element 274 disposed between the first movable seat 271 and the first swing arm 272; in the fifth position, the first pressing wheel 273 can be spaced apart from the workpiece on the bearing unit 21; in the sixth position, the first pressing wheel 273 can press the material strip tightly onto the workpiece on the bearing unit 21.

[0047] In other words, such as Figure 4 As shown, the pressing unit 27 mainly includes a second moving component, a first swing arm 272, and a first pressing wheel 273. The second moving component is a pneumatic slide structure, fixedly connected to the upper side of the connecting seat 25. A first movable seat 271 is fixedly connected to the slider of the second moving component. The first swing arm 272 is rotatably mounted on the first movable seat 271 about an axis extending in the height direction of the base 10. The first pressing wheel 273 is rotatably mounted on the first swing arm 272 about its axis. A first elastic element 274 (e.g., a tension spring) is provided between the first swing arm 272 and the first movable seat 271. The first end of the first elastic element 274 is attached to the first swing arm 272, and the second end of the first elastic element 274 is attached to the first movable seat 271. The driving structure of the second moving component can drive the first movable seat 271 to move between a fifth position and a sixth position, wherein the fifth position is away from the bearing unit 21, and the sixth position is close to the bearing unit 21.

[0048] When the first movable seat 271 is in the fifth position, the first pressure roller 273 is spaced apart from the workpiece mounting position on the bearing unit 21, which facilitates the loading and unloading of the workpiece; when the first movable seat 271 is in the sixth position, the first pressure roller 273 contacts the material strip on the outer periphery of the workpiece on the bearing unit 21, and the first pressure roller 273 presses the material strip tightly onto the surface of the workpiece under the action of the first elastic element 274, and rotates synchronously with the workpiece.

[0049] In this embodiment, the first elastic element 274 provides a buffering effect to the clamping force of the first pressure roller 273, which can prevent excessive pressure from causing damage to the strip or deformation of the workpiece, and ensure that the strip and the workpiece are closely attached. At the same time, the rotatable first pressure roller 273 reduces the friction during the winding process, reduces strip wear, and ensures the sealing performance of the strip.

[0050] In some specific embodiments of this application, the feeding device 20 further includes: a limiting unit, the limiting unit being disposed on the connecting seat 25, the limiting unit having a limiting member 28 movable between a seventh position and an eighth position; in the seventh position, the limiting member 28 is spaced apart on the upper side of the carrying unit 21, the limiting member 28 cooperating with the carrying unit 21 to limit the position of the material strip in the workpiece axial direction; in the eighth position, the limiting member 28 can avoid the workpiece on the carrying unit 21.

[0051] Specifically, such as Figure 4 and Figure 5 As shown, the feeding device 20 is equipped with a limiting unit located beside the bearing unit 21. The limiting unit includes a second driving member, a first support, and a limiting member 28. The second driving member is fixedly connected to the connecting seat 25, the first support is fixedly connected to the output end of the second driving member, and the limiting member 28 is fixedly connected to the first support. The second driving member can drive the limiting member 28 to move between a seventh position and an eighth position along a direction perpendicular to the workpiece rotation axis. The seventh position is close to the workpiece rotation axis, and the eighth position is away from the workpiece rotation axis.

[0052] When the limiting member 28 is in the seventh position, it is located above the bearing unit 21 and the clutch unit 23, forming an axial limiting space between the limiting member 28 and the upper surface of the bearing unit 21. During the strip winding process, the limiting member 28 and the bearing unit 21 restrict the axial displacement of the strip on the workpiece, ensuring accurate strip winding position and preventing the strip from shifting after cutting, thus ensuring the quality of strip winding. When the limiting member 28 is in the eighth position, it can avoid the workpiece on the bearing unit 21, facilitating the loading or unloading of the workpiece.

[0053] According to one embodiment of this application, the feeding device 20 further includes a clamping unit 29, which is disposed on the movable seat 26 and located between the clutch unit 23 and the unwinding unit 22, and is configured to clamp and fix the material strip before the cutting unit 24 cuts the material strip.

[0054] In other words, a clamping unit 29 is provided between the clutch unit 23 and the unwinding unit 22. The clamping unit 29 can be a pneumatic gripper. The clamping unit 29 is fixedly connected to the movable seat 26, and the strip provided by the unwinding unit 22 passes between the two clamping arms of the clamping unit 29. When the workpiece needs to be cut after being wound with the strip a predetermined number of times, the clamping unit 29 first clamps and fixes the strip between the clutch unit 23 and the unwinding unit 22, and then the cutting unit 24 cuts the strip connected to the workpiece. This can prevent the strip from being pulled during the cutting process and causing the unwinding unit 22 to unwind, ensuring that the strip provided by the unwinding unit 22 is always in a taut state.

[0055] In this embodiment, the clamping unit 29 simplifies the structure of the cutting unit. For example, the cutting unit 24 may include a third driving member and a blade body. The third driving member is fixedly connected to the connecting seat 25, and the blade body is fixedly connected to the output end of the third driving member. Cutting can be achieved by driving the blade body close to the strip between the workpiece and the clutch unit 23.

[0056] In some specific embodiments of this application, the clutch unit 23 includes: a second pressure roller 231, which is rotatably disposed on the movable seat 26, and is used to separate or adhere the material strip to the workpiece; a second swing arm 232 and a clamping roller 233, which are rotatably disposed on the movable seat 26 and the clamping roller 233 are rotatably disposed on the second swing arm 232; and a second elastic element 234, which is disposed between the second swing arm 232 and the movable seat 26, and the second pressure roller 231 and the clamping roller 233 cooperate to clamp the material strip.

[0057] Specifically, such as Figure 4 and Figure 5 As shown, the clutch unit 23 includes a second pressure roller 231, a second swing arm 232, and a clamping roller 233. A second support and a fixed shaft are provided on the upper side of the movable seat 26. The second pressure roller 231 is rotatably mounted on the second support about its axis. The second swing arm 232 is rotatably sleeved on the fixed shaft. The clamping roller 233 is rotatably mounted on the second swing arm 232 about its axis. A second elastic element 234 (e.g., a tension spring) is provided between the second swing arm 232 and the second support. The first end of the second elastic element 234 is attached to the second swing arm 232, and the second end is attached to the second support. The second elastic element 234 can provide a clamping force to the clamping roller 233 that tends towards the second pressure roller 231, so that the clamping roller 233 cooperates with the second pressure roller 231 to clamp the material strip passing between them.

[0058] In this embodiment, rotating the second swing arm 232 can increase the gap between the clamping wheel 233 and the second pressure wheel 231, thereby facilitating the threading of the material strip; after releasing the second swing arm 232, the elastic force of the second elastic member 234 causes the clamping wheel 233 and the second pressure wheel 231 to cooperate and clamp the material strip.

[0059] In some optional examples of this application, a plurality of reversing wheels that cooperate with the material strip are provided between the clamping unit 29 and the unwinding unit 22. The reversing wheels are rotatably mounted on the movable seat 26 about their axes. In addition, the outer periphery of the reversing wheels and the clamping wheels are provided with annular grooves corresponding to the material strip, thereby restricting the position of the material strip in the height direction and preventing it from deviating.

[0060] According to one embodiment of this application, the feeding device 20 further includes an air blowing member 261, which is disposed on the movable seat 26. The air blowing member 261 is used to blow the free end of the material strip toward the second pressure roller 231 so that the material strip adheres to the outer peripheral surface of the second pressure roller 231.

[0061] In other words, such as Figure 4 As shown, an air blowing component 261 is fixedly connected to the upper side of the movable seat 26. The air blowing component 261 is located beside the second pressure roller 231, and its air blowing port faces the outer peripheral surface of the second pressure roller 231. The airflow blown out by the air blowing component 261 can blow the material strip towards the outer peripheral surface of the second pressure roller 231 and make it adhere, which can effectively prevent the starting end of the material strip from sagging or wrinkling, thereby ensuring the winding quality of the material strip.

[0062] In some specific embodiments of this application, the bearing unit 21 includes a workpiece support 211, which is rotatably disposed on the base 10 about its axis; the bearing unit 21 also includes a first driving mechanism 212, which is disposed on the base 10 and whose output end is connected to the workpiece support 211; and / or, the pressing assembly 42 is provided with a second driving mechanism, the output end of which is connected to the pressing member 421.

[0063] Specifically, such as Figure 3 As shown, the supporting unit 21 includes a workpiece support 211. A third support is fixedly connected to the upper side of the connecting seat 25. The workpiece support 211 is rotatably mounted on the third support around its axis, and its upper side is provided with a contour groove adapted to the shape of the workpiece to support and position the workpiece. When winding the material strip, the workpiece can be driven to rotate by the supporting unit 21 and / or the pressing device 40. That is to say, the structure of the supporting unit 21 and the pressing assembly 42 includes, but is not limited to, the following two cases: In the first scenario, the supporting unit 21 also includes a first driving mechanism 212 (e.g., a motor). The first driving mechanism 212 is fixedly connected to the connecting seat 25, and its output end is fixedly connected to the workpiece support 211. When the material strip is wound, the workpiece support 211 rotates actively, and the pressing part 421 rotates passively. In the second scenario, the pressing assembly 42 also includes a second drive mechanism (e.g., a motor). The second drive mechanism is fixed to the mounting base, and its output end is fixedly connected to the pressing member 421. When the material strip is wound, the pressing member 421 rotates actively, and the workpiece support member 211 rotates passively.

[0064] According to one embodiment of this application, the material strip winding device further includes: a body 50, a base 10 disposed within the body 50, and a feeding device 20 movably disposed on the base 10 between a ninth position and a tenth position; in the ninth position, the feeding device 20 is located within the body 50; in the tenth position, at least a portion of the feeding device 20 is located outside the body 50.

[0065] Specifically, such as Figure 1 and Figure 2 As shown, the strip winding equipment includes a body 50, with an openable protective door on one side of the body 50 in the first direction. A base 10 is fixedly connected to a mounting bracket inside the body 50. The connecting seat 25 of the feeding device 20 is movably disposed on the upper side of the base 10 between the ninth and tenth positions along the first direction. In the ninth position, the feeding device 20 is close to the pressing device 40 and located inside the body 50. In this position, the feeding device 20 works in conjunction with the conveying device 30 and the pressing device 40 to achieve automated winding of the workpiece strip. In the tenth position, the feeding device 20 is away from the pressing device 40 and at least partially located outside the body 50, thus facilitating the installation and replacement of the strip.

[0066] In this embodiment, the body 50 can effectively isolate external dust and impurities, further ensuring the cleanliness of optical workpieces and improving product quality; the feeding device 20 can be movably set in different positions, facilitating the installation and replacement of the feed strip.

[0067] It should be noted that the feeding device 20 can be driven by the drive structure to move between the ninth and tenth positions, or it can be pulled manually. When no drive structure is set, the connecting seat 25 is fixedly connected to the side near the protective door. When replacing, open the protective door and pull the handle to pull the feeding device 20 to the tenth position.

[0068] In some optional examples of this application, the upper side of the base 10 is provided with a first limiting seat and a second limiting seat distributed at intervals along a first direction, and the feeding device 20 moves between the first limiting seat and the second limiting seat. When the feeding device 20 is in the ninth position, the connecting seat 25 abuts against the first limiting seat; when the feeding device 20 is in the tenth position, the connecting seat 25 abuts against the second limiting seat.

[0069] In this example, the first limiting seat ensures that the feeding device 20 moves accurately to the ninth position, and the second limiting seat effectively prevents the feeding device 20 from detaching from the base 10.

[0070] According to some embodiments of this application, a locking unit is provided between the feeding device 20 and the base 10, the locking unit being used to lock the feeding device 20 in the ninth position.

[0071] In this embodiment, the feeding device 20 is switched between the ninth and tenth positions by manual pushing and pulling. At this time, a locking unit is provided between the feeding device 20 and the base 10. The locking unit adopts a pin cylinder, the cylinder body of which is fixed to the base 10, and the connecting seat 25 is provided with a corresponding pin hole. When the feeding device 20 is in the ninth position, the pin of the pin cylinder extends out and is inserted into the pin hole to ensure that the feeding device 20 is locked in the working state and prevents displacement.

[0072] In some specific embodiments of this application, the material strip winding device further includes: a feeding transfer unit 60, which is disposed on the base 10, and has a first material tray 61 movable between the feeding position and the first transfer position; the first material tray 61 is used to receive the workpiece at the feeding position and transfer it to the first transfer position to provide the workpiece to the conveying device 30; and / or, an unloading transfer unit 70, which is disposed on the base 10, and has a second material tray 71 movable between the second transfer position and the unloading position; the second material tray 71 is used to receive the workpiece moved away by the conveying device 30 at the second transfer position and transfer it to the unloading position.

[0073] In other words, such as Figure 2As shown, a loading transfer unit 60 is provided on the upper side of the base 10. The loading transfer unit 60 includes a third moving component and a first material tray 61. The third moving component can be a pneumatic slide, and its base is fixedly connected to the base 10. The first material tray 61 is fixedly connected to the slider of the third moving component. The third moving component can drive the first material tray 61 to move between the loading position and the first transfer position along a second direction (e.g., the width direction of the base 10). When the first material tray 61 is in the loading position, it can receive workpieces from the loading device that are to be wound with the material strip; when the first material tray 61 is in the first transfer position, it can provide workpieces to be wound with the material strip to the conveying device 30.

[0074] The upper side of the base 10 is also provided with an unloading transfer unit 70, which includes a fourth moving component and a second material tray 71. The fourth moving component can be a pneumatic slide, and its base is fixedly connected to the base 10. The second material tray 71 is fixedly connected to the slider of the fourth moving component, and can be driven by the fourth moving component to move between the second transfer position and the unloading position along a second direction. When the second material tray 71 is in the second transfer position, it can receive the workpiece with completed material strip winding that has been moved away by the conveying device 30. When the second material tray 71 is in the unloading position, it is located outside the machine body 50, facilitating the removal of the workpiece with completed material strip winding.

[0075] In this embodiment, by setting up a loading transfer unit 60 and an unloading transfer unit 70, a buffer station can be formed between the handling device 30 and the upstream and downstream devices, so that the handling device 30 can pick up and place workpieces at a fixed transfer position without waiting for external loading or unloading, thereby significantly improving the automated continuous operation capability and shortening the production cycle.

[0076] According to one embodiment of this application, the material strip winding device further includes: a barcode scanning unit 80, which is disposed on the base 10 and is used to scan the workpiece on the first material tray 61 located at the first transfer position; and / or a vision guidance unit 90, which is disposed on the base 10 and is used to photograph and position the workpiece on the first material tray 61 located at the first transfer position.

[0077] Specifically, such as Figure 2As shown, a barcode scanning unit 80 and a vision guidance unit 90 are located on the upper side of the base 10, both situated beside the first transfer position. The barcode scanning unit 80 scans the identification information (such as product model and production batch) on the workpiece located at the first transfer position and transmits this information to the control system for product traceability management. The vision guidance unit 90 photographs the workpiece located at the first transfer position to obtain its location information and transmits this information to the control system. The control system then adjusts the picking and placing position of the handling device 30 accordingly to ensure that the handling device 30 accurately picks up the workpiece.

[0078] According to one embodiment of this application, the handling device 30 includes: a robotic arm 31, the robotic arm 31 being disposed on the base 10, the robotic arm 31 having two pick-and-place units 32, one of which is capable of removing the workpiece from the bearing unit 21, and the other of which is capable of transporting the workpiece to the bearing unit 21.

[0079] Specifically, such as Figure 7 As shown, the conveying device 30 includes a robotic arm 31, which can be a four-axis robotic arm 31. A third motor 311 is located at the end of the robotic arm 31, and a mounting plate is fixedly connected to the output end of the third motor 311. Two pick-and-place units 32 are provided on the mounting plate. One of the two pick-and-place units 32 can remove the wound workpiece from the carrier unit 21, and the other can transport the workpiece to be wound onto the carrier unit 21. Each pick-and-place unit 32 includes a picking assembly, the number of which is the same as the number of carrier units 21 in the feeding device 20. The picking assembly includes a vertically arranged fourth drive member 321 (e.g., a cylinder) and a suction cup 322 located at the output end of the fourth drive member 321. The fourth drive member 321 controls the up-and-down movement of the suction cup 322 to facilitate the picking and placing of workpieces.

[0080] In this embodiment, the third motor 311 drives the mounting plate to rotate, enabling the position switching of the two pick-and-place units 32, allowing them to alternately align with the support unit 21 of the feeding device 20. During operation, one pick-and-place unit 32 removes the workpiece that has been wound on the support unit 21; then, it drives the mounting plate to rotate, causing the other pick-and-place unit 32 to align with the support unit 21 and transport the workpiece to be processed to the support unit 21. This allows for synchronous pick-and-place operations, effectively improving production efficiency.

[0081] In an optional example of this application, such as Figure 3 and Figure 3 As shown, the feeding device 20 is equipped with two bearing units 21, and the other units of the feeding device 20 are also equipped with two units. The number of pressing devices 40 corresponds to the number of feeding devices 20, so as to realize parallel operation of two stations.

[0082] In some specific embodiments of this application, the material strip winding device includes two feeding devices 20 and a pressing device 40 corresponding one-to-one with the carrying unit 21.

[0083] Specifically, such as Figure 2 As shown, the material strip winding equipment is equipped with two feeding devices 20, which are arranged at intervals along the second direction. The number of pressing devices 40 matches the number of carrying units 21 of the feeding devices 20. The two feeding devices 20 can operate independently. When one device is changing or maintaining the material strip, the other device can still continue to operate, thereby avoiding equipment downtime and ensuring production continuity.

[0084] In summary, the tape winding equipment provided in this embodiment, through the coordinated action of the feeding device 20, the conveying device 30, and the pressing device 40, can realize the automated operation of the workpiece tape winding process, significantly improving production efficiency. At the same time, the fully automated process greatly reduces manual intervention, effectively reduces the risk of contamination by dust, fingerprints, and other impurities, improves the cleanliness and reliability of optical lenses, and eliminates individual differences caused by manual operation, ensuring a high degree of consistency in the winding effect of each workpiece.
