Description

Technical Field

[0001] The invention relates to the field of film peeling and film sticking automation equipment technology, in particular to an integrated film peeling and film sticking automation equipment. Background Art

[0002] At present, some of the double-sided tapes are pasted on the workpiece manually. As we all know, manual work is inefficient and the consistency of work quality is not ideal. However, for most manufacturers that have introduced semi-automatic equipment or automated equipment, they can realize automatic film tearing and automatic film pasting. Take the glass panel as an example. Usually, the surface of the glass panel is covered with a protective film. If you need to paste double-sided tape on the surface of the glass panel, you need to tear off the protective film on the glass panel first, and then prepare the double-sided tape to be pasted, paste the double-sided tape on the glass panel after removing the protective film, and then tear off the protective film of the double-sided tape.

[0003] In the whole process, step one: generally a film-tearing device is needed to tear off the protective film on the glass panel. The glass panels with the protective film torn off are carried one by one on various carriers. These carriers are stacked together in a stack. Some of the glass panels with the protective film torn off are arranged at intervals on the material tray. In this way, the automatic protective film-tearing process of the glass panel is completed. Step two: film-sticking equipment is also needed. The film-sticking equipment automatically sticks double-sided tape on the glass panel. The glass panel with the protective film torn off obtained in step one is loaded as a workpiece to the film-sticking station of the film-sticking equipment. After the double-sided tape is stuck on the glass panel, the glass panel with the double-sided tape is unloaded. Usually, the material is circulated in the form of "carriers stacked in a stack" or "arranged at intervals on the material tray". Step 3: A film-tearing device is also required. The glass panels covered with double-sided tape obtained in step 2 are loaded onto the film-tearing device one by one, and the protective film on the double-sided tape surface of the glass panels covered with double-sided tape is torn off. Then, the glass panels with double-sided tape are circulated in the same manner of "stacked carriers" or "arranged at intervals on a material tray".

[0004] Although this type of automated operation method can use automated film tearing equipment to complete automatic film tearing and automated film sticking equipment to achieve automatic film sticking, there are still many links that require manual participation, especially between film tearing equipment-film sticking equipment-film tearing equipment. The material turnover leads to repeated loading and unloading, and the transfer of material piles between different equipment. On the one hand, it will take up a lot of time, resulting in a longer entire operation cycle and affecting the overall operation efficiency. On the other hand, repeated loading, unloading and turnover will inevitably require repeated positioning and correction, which increases the difficulty of positioning and is not conducive to the overall operation accuracy and quality. On the other hand, multiple devices need to be dispersed in the workshop, which occupies a large space, is not conducive to workshop management, and undoubtedly increases the operating and management costs of manufacturers.

[0005] Therefore, it is necessary to study a new technical solution to solve the above problems. Summary of the invention

[0006] In view of this, the present invention aims at the deficiencies in the prior art, and its main purpose is to provide an integrated automated film peeling and sticking equipment, which arranges each workstation in sequence along the circular conveyor track through the arrangement of a circular conveyor track, and utilizes a plurality of jigs to move to each workstation along the circular conveyor track. Therefore, after the workpiece loading device loads the workpiece to the jig at the loading station, the workpiece on the same jig can automatically operate in each device through each workstation in sequence along the circular conveyor track until it is automatically unloaded at the unloading station through the unloading device, thereby realizing integrated fully automated operation, eliminating the repeated loading and unloading and material turnover in traditional technology, having a high degree of automation, and better meeting the requirements of accurate workpiece delivery, which is beneficial to improving operation accuracy and quality.

[0007] To achieve the above purpose, the present invention adopts the following technical solutions:

[0008] An integrated film peeling and pasting automated equipment comprises a frame and a circular conveying track arranged on the frame, wherein a plurality of jigs for placing workpieces are arranged on the circular conveying track; a workpiece loading station, a workpiece protective film angle starting station, a workpiece protective film stripping station, a workpiece cleaning station, a workpiece double-sided adhesive pasting station, a double-sided adhesive protective film angle starting station, a double-sided adhesive protective film stripping station and a material unloading station are arranged in sequence along the circular conveying track; and the jigs are driven by a conveying drive device to move to each station along the circular conveying track;

[0009] In addition, the frame is equipped with a workpiece loading device, a workpiece protective film angle raising device, a workpiece protective film peeling device, a workpiece cleaning device, a workpiece double-sided tape sticking device, a double-sided tape protective film angle raising device, a double-sided tape protective film peeling device and a unloading device in sequence corresponding to each workstation.

[0010] Compared with the prior art, the present invention has obvious advantages and beneficial effects. Specifically, it can be seen from the above technical scheme that: it arranges each workstation in sequence along the circular conveyor track through the arrangement of a circular conveyor track, and uses a number of jigs to move to each workstation along the circular conveyor track. Therefore, after the workpiece loading device loads the workpiece to the jig at the loading station, the workpiece on the same jig can automatically operate in each device through each workstation in sequence along the circular conveyor track until it is automatically unloaded at the unloading station through the unloading device, realizing integrated fully automated operation, eliminating repeated loading and unloading and material turnover in traditional technology, with a high degree of automation, and can better meet the requirements of accurate workpiece transportation, which is beneficial to improving operation accuracy and quality.

[0032] An integrated automatic film peeling and sticking equipment comprises a frame and an annular conveying track arranged on the frame, wherein a plurality of jigs for placing workpieces are arranged on the annular conveying track; a workpiece loading station 1, a workpiece protective film angle raising station 2, a workpiece protective film stripping station 3, a workpiece cleaning station 4, a workpiece double-sided adhesive sticking station 5, a double-sided adhesive protective film angle raising station 6, a double-sided adhesive protective film stripping station 7 and a material unloading station 8 are arranged in sequence along the annular conveying track; the jigs are driven by a conveying driving device to move to each station along the annular conveying track; and a workpiece loading device 1', a workpiece protective film angle raising device 2' (used for angle raising the protective film on the workpiece), a workpiece protective film stripping device 3', a workpiece cleaning device 4', a workpiece double-sided adhesive sticking device 5', a double-sided adhesive protective film angle raising device 6', a double-sided adhesive protective film stripping device 7' and a material unloading device 8' are arranged in sequence on the frame corresponding to each station.

[0033] Next, the following steps are introduced in order:

[0034] 1. A workpiece with a protective film (such as glass) is automatically sent to a jig at a workpiece loading station 1 by a workpiece loading device 1' (also referred to as a loading robot). Before the workpiece is transported to the jig, the movable limiting portion of the jig is slightly away from the jig to facilitate the placement of the workpiece. After the workpiece is placed on the jig, the movable limiting portion of the jig moves toward the jig. The workpiece is positioned along the XY direction against the reference edge under the action of the V-shaped limiting surface, so that the workpiece is accurately and reliably positioned on the jig.

[0035] 2. Subsequently, the jig moves along the circular conveying track to the workpiece protective film angle starting station 2, and the movable vacuum pumping assembly arranged on the side of the workpiece protective film angle starting station 2 starts to work, and the vacuum pumping joint moves toward the side of the jig until the second interface hole is connected to the first interface hole, and the jig fixes the glass by vacuum adsorption; the protective film on the glass is angled by the workpiece protective film angle starting device 2', and the protective film angle starting device can usually be used to fold the protective film after angle starting, so as to facilitate better positioning and clamping when the protective film is subsequently peeled off. The side of the scraper of the workpiece protective film angle starting device 2' needs to be treated with non-adhesive. For example, corrugated paper can be pasted on the side of the scraper, so that the double-sided tape is easy to fall off, solving the problem of the double-sided tape sticking to the side of the scraper. When the jig needs to move from the workpiece protective film angle starting station 2 to the workpiece protective film peeling station 3, the movable vacuum pumping assembly first controls the vacuum pumping joint to separate from the side of the jig;

[0036] 3. Subsequently, the fixture moves along the circular conveyor track to the workpiece protective film stripping station 3, and the movable vacuum pumping assembly arranged beside the workpiece protective film stripping station 3 starts to work, so that the fixture vacuum absorbs and fixes the glass, and then the workpiece protective film stripping device 3' (the workpiece protective film stripping device 3' usually includes a clamping jaw 301' and a driving device 302' that controls the XYZ three-axis movement of the clamping jaw 301', such as Fig.16 As shown in the figure, the protective film on the glass is completely peeled off. When the waste glue is peeled and moved to the vacuum waste barrel, the optical fiber is used to detect whether there is peeling. If there is peeling, it means that the protective film on the glass is peeled off successfully, and the glass is sent to the next station, i.e., the workpiece cleaning station 4, as an OK product. If there is no peeling, it means that the protective film on the glass is not peeled off successfully, and the glass will pass through the subsequent stations as an NG product according to the normal process, but no corresponding operation is required at the corresponding station until the unloading device 8' directly transfers the NG product to the unqualified product output device.

[0037] 4. Similarly, when the jig needs to move from the workpiece protective film stripping station 3 toward the workpiece cleaning station 4, the movable vacuum pumping assembly first controls the vacuum pumping joint to separate from the side of the jig; then, the jig moves along the circular conveying track to the workpiece cleaning station 4, and the movable vacuum pumping assembly arranged beside the workpiece cleaning station 4 starts to work, so that the jig vacuum absorbs and fixes the glass, and then the workpiece cleaning device 4' wet-cleans the glass surface (specifically, the surface after the protective film is stripped), and the dripping head of the workpiece cleaning device 4' will regularly wet the wiping cloth 40 2', the cleaning transfer module 401' of the workpiece cleaning device 4' drives the cleaning roller pressing cylinder 403' and the wiping cloth 402' to move horizontally along the conveying direction of the workpiece cleaning station 4 at a right angle to the current fixture, so as to repeatedly wipe the glass surface. The cleaning roller pressing cylinder 403' can control the lifting and lowering of the wiping cloth to ensure the contact pressure between the wiping cloth and the glass surface. At the same time, the wiping cloth retracting and releasing motor 404' of the workpiece cleaning device 4' can also control the displacement of the wiping cloth to change the position of the wiping cloth to wipe the surface of the current glass (such as Fig.17 shown).

[0038] 5. Similarly, when the jig needs to move from the workpiece cleaning station 4 to the workpiece double-sided adhesive station 5, the movable vacuum pumping assembly first controls the vacuum pumping joint to separate from the side of the jig; then, the jig moves along the circular conveying track to the workpiece double-sided adhesive station 5, and the movable vacuum pumping assembly arranged beside the workpiece double-sided adhesive station 5 starts to work, so that the jig vacuum absorbs and fixes the glass; the workpiece double-sided adhesive device 5' includes a film transfer module 501', a stripping knife cylinder 502', a film roller pressing cylinder 503', and a film winding and unwinding motor 504'. The film transfer module 501' drives the stripping knife cylinder, the film roller pressing cylinder, and the film winding and unwinding motor to move horizontally, and the direction of translation is perpendicular to the conveying direction of the workpiece double-sided tape sticking station 5 where the current fixture is located; the stripping knife cylinder drives the stripping knife to remove the double-sided tape with a protective film, and then under the action of the film roller pressing cylinder, the film roller is pressed downward toward the double-sided tape with a protective film, so that the double-sided tape with a protective film is gradually attached to the upper surface of the glass. After the attachment work is completed, the entire workpiece double-sided tape sticking device 5' is translated away from the fixture (such as Fig.18 shown).

[0039] 6. Similarly, when the jig needs to move from the workpiece double-sided tape sticking station 5 toward the double-sided tape protective film angle starting station 6, the movable vacuum pumping component first controls the vacuum pumping joint to separate from the side of the jig; then, the jig moves along the circular conveying track to the double-sided tape protective film angle starting station 6, and the movable vacuum pumping component arranged on the side of the double-sided tape protective film angle starting station 6 starts to work, so that the jig vacuum absorbs and fixes the glass; the protective film on the double-sided tape is angled by the double-sided tape protective film angle starting device 6', and the double-sided tape protective film angle starting device 6' can usually also be used to fold the protective film after the angle is raised, so as to facilitate better positioning and clamping when the protective film is subsequently peeled off. Here, a boss is provided at the bottom of the scraper for angle raising (in actual production, the boss may be a boss structure formed when the scraper is manufactured. Preferably, a gasket may be pasted at the rear of the bottom of the scraper away from the blade according to the actual thickness of the double-sided adhesive, so that the gasket is in a boss shape relative to the bottom of the blade. The thickness of the gasket (or the distance between the bottom surface of the gasket and the bottom surface of the blade after the gasket is pasted) is the thickness value of the double-sided adhesive, and the thickness of the boss is the thickness value of the double-sided adhesive. Since the distance between the upper surface of the glass and the upper surface of the double-sided adhesive is constant, and the distance between the bottom surface of the gasket and the bottom surface of the blade is constant, the bottom surface of the gasket is against the upper surface of the glass, so that the blade uses the glass surface as a height reference surface. In this way, the blade of the scraper can operate directly against the protective film on the double-sided adhesive and the portion between the double-sided adhesive to raise the protective film. The success rate of angle raising is high. It is feasible and reliable to peel off the protective film at a fixed distance with the glass surface as the reference surface.

[0040] 7. Similarly, when the jig needs to move from the double-sided adhesive film cornering station 6 toward the double-sided adhesive film stripping station 7, the movable vacuum pumping component first controls the vacuum pumping joint to separate from the side of the jig; then, the jig moves along the circular conveying track to the double-sided adhesive film stripping station 7, and the movable vacuum pumping component arranged on the side of the double-sided adhesive film stripping station 7 starts to work, so that the jig vacuum absorbs and fixes the glass; then the double-sided adhesive film stripping device 7' completely strips off and removes the protective film on the double-sided adhesive. In the middle of the protective film stripping, the height measuring cylinder is used to drive the height detection probe reference column to contact the upper surface of the glass (the double-sided adhesive does not completely cover the glass, and usually there is an area around the glass where no double-sided adhesive is attached), and the height probe measures the thickness of the double-sided adhesive film.

[0041] 8. Similarly, when the jig needs to move from the double-sided adhesive protective film peeling station 7 to the unloading station 8, the movable vacuum assembly first controls the vacuum joint to detach from the side of the jig; then, the jig moves along the circular conveyor track to the unloading station 8. At this time, the movable limit part of the jig opens away from the jig, which is convenient for the unloading device 8' (also referred to as the unloading manipulator) to take the workpiece out of the jig. After the aforementioned height probe measures the thickness of the double-sided adhesive film, the thickness that meets the standard is a good product (also called OK product), and the thickness that does not meet the standard is a defective product (also called NG product). The inspection result of the current workpiece has been fed back to the main control system of the equipment in real time. Therefore, the main control system can control the unloading device 8' to transfer the good product to the good product output device and the defective product to the defective product output device according to the inspection result. The good product output device and the defective product output device usually use a belt output line.

[0042] like Figures 3 to 6 As shown, the annular conveying track includes an annular track base 10, an annular conveying belt 20, a conveying drive device 30, a plurality of fixtures 40 and a fixture limiting assembly 50; wherein:

[0043] The annular track base 10 is arranged in an annular shape. The annular track base 10 is provided with an annular guide rail 11 extending along the annular track base 10. Here, the annular guide rail 11 is a convex guide rail protruding from the top of the annular track base 10. The annular guide rail 11 has more than two straight guide rail sections 111, and adjacent straight guide rail sections 111 are connected by arc-shaped guide rail sections 112.

[0044] The annular conveyor belt 20 is located on the inner side of the annular guide rail 11 and extends in the same direction along the annular guide rail 11. The jig 40 is connected to the annular conveyor belt 20. Preferably, the jig 40 is connected to the outer side of the annular conveyor belt 20, so that the annular conveyor belt 20 moves more smoothly along the driving pulley 31 and the driven pulley 32. The jig 40 is adapted to the annular guide rail 11 and is slidably arranged along the annular guide rail 11. The conveying drive device 30 drives the annular conveyor belt 20 to move along the extension direction of the annular guide rail 11, so that the jig 40 moves along the annular guide rail 11. Preferably, the conveying drive device 30 is a motor, and the motor is driven and connected to the driving pulley 31. The annular conveyor belt 20 is sleeved on the driving pulley 31. There are more than one driven pulley 32 spaced apart along the annular conveying extension direction, and the annular conveyor belt 20 is sleeved on the driven pulley 32 in sequence. The driving pulley 31 and the driven pulley 32 are respectively arranged corresponding to the arc-shaped guide rail section 112. In this embodiment, the annular guide rail 11 has four straight guide rail sections 111, so four arcuate guide rail sections 112 are required for connection. Pulley mounting plates 113 are respectively provided on the inner side of the annular track base 10 corresponding to the four arcuate guide rail sections 112, and the driving pulley 31 and the driven pulley 32 are respectively installed on the pulley mounting plates 113.

[0045] The jig limit assembly 50 includes a stop drive device 51 and a swing mechanism, the swing mechanism has a stop portion 531, and the jig 40 is provided with a stop groove 41, where the stop groove 41 is provided on the outside of the jig 40, and the swing mechanism is located on the outside of the annular guide rail 11; in the first state, the stop drive device 51 drives the swing mechanism to swing toward the jig 40 until the stop portion 531 is limited in the stop groove 41; in the second state, the stop drive device 51 drives the swing mechanism to swing away from the jig 40 so that the stop portion 531 escapes from the stop groove 41; in this way, combined with the start and stop of the conveying drive device 30 and the jig limit assembly 50, the jig 40 is dually controlled to ensure that the sliding and pause state control of the jig 40 is accurate and reliable. Usually, multiple stop portions 531 are provided on the same straight guide rail section 111 to meet the needs of multiple workstations. Multiple stop parts 531 are all connected to the same rotating shaft, and the stop driving device 51 drives the rotating shaft to rotate so that the stop part 531 swings accordingly with the rotating shaft. The stop driving device 51 can be a cylinder, which is arranged at the bottom of the annular track base 10, and the piston rod of the cylinder extends forward. The swing mechanism includes a first swing rod 52 and a second swing rod 53, the upper end of the first swing rod 52 is connected to the rotating shaft, and the lower end of the second swing rod 53 is connected to the rotating shaft 54, the piston rod is hinged to the lower end of the first swing rod 52, and the stop part 531 is arranged at the upper end of the second swing rod 53. By arranging the cylinder at the bottom of the annular track base 10, the rotating shaft 54 ​​and the swing mechanism at the outside of the annular track base 10, the fixture 40 at the top of the annular track base 10, and the annular conveyor belt 20 at the inside of the annular track base 10, the structural design is ingenious, reasonable and very compact. In this way, the entire annular conveyor track occupies a small space, which is conducive to the application of this type of annular conveyor track in automation equipment.

[0046] An annular conveyor belt positioning groove 12 is provided on the inner side of the annular track base 10, and the annular conveyor belt 20 passes through the annular conveyor belt positioning groove 12. An L-shaped positioning frame extends from the inner side of the annular track base 10, and the L-shaped positioning frame has a transverse portion 131 and a vertical portion 132 connected to the inner end of the transverse portion 131, and the annular conveyor belt positioning groove 12 is formed between the upper side of the transverse portion 131 and the outer side of the vertical portion 132.

[0047] Furthermore, the bottom of the fixture 40 is connected to two sets of guide wheels 42 on the left and right spacing surfaces, respectively, and the two sets of guide wheels 42 are respectively located on the left and right sides of the annular guide rail 11. The setting of the guide wheels 42, on the one hand, plays the role of combining the fixture 40 with the annular guide rail 11 to position and prevent left and right deviation, and on the other hand, the guide wheels 42 are conducive to improving the smoothness of the sliding of the fixture 40 along the annular guide rail 11 to avoid jamming.

[0048] Main reference Figures 7 to 9As shown, the jig 40 includes a jig body and a fixed limiting portion 401. The frame corresponding to the workpiece loading station 1, the workpiece protective film angle starting station 2, the workpiece protective film stripping station 3, the workpiece cleaning station 4, the workpiece double-sided adhesive sticking station 5, the double-sided adhesive protective film angle starting station 6, the double-sided adhesive protective film stripping station 7 and the unloading station 8 are all provided with movable limiting portions and control components for controlling the movable limiting portion 402 to selectively move toward or away from the jig body; wherein: a workpiece placement position 101 is provided on the top of the jig body; the movable limiting portion 402 and the fixed limiting portion are spaced around the workpiece placement position 101, and the fixed limiting portion 30 is fixed relative to the jig body. The fixture body is quadrilateral, the fixed limiting portion 30 is respectively provided on two adjacent sides of the fixture body to limit the two adjacent sides of the workpiece placement position 101, the movable limiting portion 402 has a V-shaped limiting surface 4021, and the V-shaped limiting surface 4021 is provided corresponding to the other two adjacent sides of the workpiece placement position 101. Preferably, the V-shaped limiting surface 4021 is provided at an angle of 90 degrees. In this embodiment, the fixture body is rectangular.

[0049] In this embodiment, the top of the jig body is provided with a plurality of vacuum adsorption holes 21 in the workpiece placement position 101, and a vacuum interface is provided on the side of the jig body. The top of the jig body is a plane, on which sheets such as diaphragms and glass sheets can be placed. The jig body is slidably arranged along an annular guide rail 11, and the control components are arranged at intervals along the annular guide rail 11 at more than two, and each control component is connected to a movable limit portion 402. When the movable fixture slides on the annular guide rail 11, the workpiece 403 can be clamped or unlocked accordingly according to the requirements of different workstations so that the workpiece 403 can be automatically picked up and placed.

[0050] The control component includes a base 60, a reset elastic member 70, a pushed member 80, a pushing member 90 and a lifting drive device 91. The reset elastic member 70 is connected between the base 60 and the movable limiting portion 402. The reset elastic member 70 provides a reset elastic force for the movable limiting portion 402 to move toward the fixture body along a set direction; the movable limiting portion 402 is connected to the pushed member 80, and the lifting drive device 91 drives the pushing member 90 to move up and down. The pushing member 90 has a linkage surface 901, and the linkage surface 901 is gradually arranged to rise toward the set direction. The lifting drive device 91 is preferably a cylinder, the piston rod of the cylinder is vertically extended upward, and the pushing member 90 is connected to the outer end of the piston rod. When the piston rod of the cylinder drives the pushing member 90 to move upward, the linkage surface 901 pushes the pushed member 80 to move away from the fixture body (also in the opposite direction of the set direction), so that the movable limiting part 402 moves away from the fixture body together with the pushing member 90, thereby releasing the clamping of the workpiece on the fixture body, and the workpiece can be taken out at this time. At this time, the reset elastic member 70 (pressure spring) is in a compressed energy storage state, and when the next workpiece is placed on the workpiece placement position 101 of the fixture body, the piston rod of the cylinder retracts into the cylinder body to drive the push member 90 to move downward, and the linkage surface 901 is separated from the push member 80, releasing the restriction on the push member 80. At this time, the push member 80 moves toward the fixture body under the reset elastic force of the reset elastic member 70. At the same time, the movable limit part 402 also moves toward the fixture body along a set direction with the push member 80 until the movable limit part 402 is tightly against the fixture body. In this way, the movable limit part 402 and the fixed limit part 30 form a clamping and positioning of the workpiece around the workpiece. The movable limit part 402 and the fixture body are kept in a constant clamping state, which is conducive to the consideration of the stability of the clamping of the workpiece.

[0051] The movable limit part 402 is connected with a slider 4022, and the base 60 is provided with a slide rail 61 extending along the set direction, and the slider 4022 is slidably arranged along the slide rail 61; the push member 80 is connected to the slider 4022. The base 60 is provided with a travel stopper 62, and the travel stopper 62 is located between the slider 4022 and the fixture body. The base 60 has a mounting portion 63 extending upward, and the reset elastic member 70 is connected between the slider 4022 and the mounting portion 63. Usually, a guide rod can be provided on the mounting portion 63, and a spring can be sleeved on the guide rod, and a through hole is provided on the slider 4022. When the slider 4022 is displaced, the through hole and the guide rod are matched, so that the slider 4022 is displaced along the guide rod. Combined with the matching of the guide rod and the through hole, and the matching of the slider 4022 and the slide rail 61, the displacement direction of the slider 4022 is double guided and positioned to ensure that the displacement action is accurate and reliable. The guide rod may also be connected to the slider 4022, and the through hole may be provided on the mounting portion 63, which is equivalent to exchanging the setting positions of the guide rod and the through hole.

[0052] The pushed member 80 has a round wheel portion 81, and the round wheel portion 81 has a circumferential surface for the linkage surface 901 to squeeze and push. The round wheel portion 81 can rotate around its own circle center, so that the cooperation between the pushing member 90 and the pushed member 80 is smoother and the jamming phenomenon is avoided. If a set direction is defined as the forward direction, the axial direction of the round wheel portion 81 is the left and right direction, and the linkage surface 901 is arranged on the rear side of the pushing member 90.

[0063] The moving seat 30' is connected to an XYZ three-axis driving device 40'. In this embodiment, the XYZ three-axis driving device 40' includes a Z-axis lifting driving device 41', an X-axis translation driving device 42', an X-axis translation slide 43, a Y-axis translation driving device 44 and a Y-axis translation slide 45; the Y-axis translation driving device 44 drives the Y-axis translation slide 45 to translate along the Y-axis, the X-axis translation driving device 42' is installed on the Y-axis translation slide 45, the X-axis translation driving device 42' drives the X-axis translation slide 43 to translate along the X-axis, the Z-axis lifting driving device 41' is installed on the X-axis translation slide 43, and the Z-axis lifting driving device 41' drives the moving seat 30' to lift and lower along the Z-axis.

[0064] During operation, the XYZ three-axis drive device 40' controls the scraper 21' to lift a corner of the protective film corresponding to the corner of the workpiece (for example, the workpiece surface has a layer of protective film), and then the upper clamp 23' is clamped on the upper side of the protective film, so that the scraper 21' and the upper clamp 23' clamp the protective film, and then, under the control of the XYZ three-axis drive device 40', the film tearing operation is achieved.

[0065] The design focus of the present invention is that it mainly arranges each workstation along the circular conveyor track in sequence through the arrangement of a circular conveyor track, and utilizes a plurality of jigs to move to each workstation along the circular conveyor track. Therefore, after the workpiece loading device 1' loads the workpiece to the jig at the loading station, the workpiece on the same jig can automatically operate in each device along the circular conveyor track through each workstation in sequence until it is automatically unloaded at the unloading station 8 through the unloading device 8', thereby realizing integrated fully automated operation, eliminating repeated loading and unloading and material turnover in traditional technology, having a high degree of automation, and better meeting the requirements of accurate workpiece delivery, which is beneficial to improving operation accuracy and quality.

[0066] Secondly, the structural design of the circular conveyor track is ingenious. Through the arrangement of a circular track base, a circular conveyor belt, a conveying drive device, several jigs and a jig limit assembly, the jig can be conveyed along a circular path and can be paused as needed. With the help of the start and stop of the conveying drive device and the jig limit assembly, the jig is dually controlled to ensure that the sliding and pause state control of the jig is accurate and reliable. Therefore, when used on automated equipment, it can better meet the requirements of accurate workpiece delivery.

[0067] Furthermore, the jig is provided with a plurality of vacuum adsorption holes, and the side of the jig has a first interface hole connected to the vacuum adsorption hole; the frame is provided with movable vacuum pumping components corresponding to the workpiece protective film cornering station 2, the workpiece protective film stripping station 3, the workpiece cleaning station 4, the workpiece double-sided tape sticking station 5, the double-sided tape protective film cornering station 6, and the double-sided tape protective film stripping station 7; when the jig moves to the corresponding station along the track, the movable vacuum pumping component of the corresponding station is used to quickly connect with the jig to form a vacuum interface, so that the jig has vacuum adsorption capacity at the corresponding station, thereby meeting the need for vacuum adsorption of the workpiece when the jig slides to the corresponding station along the track.

[0068] In addition, by providing movable limiting parts and control components that control the movable limiting parts to selectively move toward or away from the fixture body on the corresponding workpiece loading station 1, workpiece protective film angle starting station 2, workpiece protective film stripping station 3, workpiece cleaning station 4, workpiece double-sided adhesive sticking station 5, double-sided adhesive protective film angle starting station 6, double-sided adhesive protective film stripping station 7 and unloading station 8 on the frame, the workpiece can be clamped and positioned or unlocked so that the workpiece can be automatically taken and placed. The structural design of the control component is ingenious and reasonable, so that the movable limiting part and the fixture body are always clamped, which is conducive to the stable clamping of the workpiece. At the same time, for the vacuum adsorbed workpiece, the clamping and positioning of the workpiece by the movable limiting part and the fixed limiting part plays a role in assisting the vacuum adsorption positioning, avoiding the problem of unsatisfactory workpiece positioning when the vacuum adsorption positioning is unstable, ensuring reliable and accurate positioning of the workpiece, which is conducive to improving the workpiece processing quality and processing accuracy, and can meet the needs of automated processing of workpieces with high processing quality and processing accuracy requirements.

[0069] In addition, the structural design of the mounting seat and the scraper assembly allows the scraper assembly to be installed at an adjustable angle relative to the mounting seat, so that the working angle of the scraper can be adjusted as needed to meet the angle requirements of different workpieces, improve the versatility of the angle mechanism, and be suitable for promotion and application. At the same time, the pressure spring is set to form an elastic contact between the scraper and the workpiece to avoid hard collision, and the workpiece will not be damaged while ensuring the contact strength.
