Description

Technical Field

[0001] This invention relates to the field of automated equipment design technology, and in particular to automated film-tearing equipment. Background Technology

[0002] With the rapid development of the smart wearable device market, smartwatches, as one of the most important categories, have experienced rapid growth in recent years. During the manufacturing process of smartwatches, the surface of the product's body (such as the watch face and frame) is usually covered with a release film or protective film to prevent scratches or contamination during transportation and assembly. Before subsequent assembly and bonding processes, this release film needs to be removed to facilitate further processing.

[0003] Currently, the primary method for removing the release film from the surface of smartwatches is manual peeling. Operators use their fingers or simple tools to peel off the edges of the release film and then remove the entire sheet from the product surface. However, this manual peeling method has several drawbacks: Firstly, it requires a large workforce, is labor-intensive and inefficient, and the peeling speed is greatly affected by the operator's skill level, making it difficult to maintain stable production efficiency. Secondly, during manual peeling, fingers directly contact the product surface, easily leaving fingerprints, dust, and other contaminants, affecting the product's cleanliness and subsequent assembly quality. Furthermore, because smartwatches are relatively delicate and fragile, uneven force during manual peeling can easily damage the product, leading to a decrease in product yield.

[0004] Therefore, finding a technical solution that can solve the above-mentioned technical problems has become an important research topic for those skilled in the art. Summary of the Invention

[0040] The automated film-tearing equipment of the present invention, through the systematic coordination of a feeding device, a first linear drive module, a positioning platform, a fixture disassembly and assembly device, an adsorption device, a film-tearing device, and a unloading device, fully realizes the automated operation of the entire process from fixture feeding, separation of the fixture parts, removal of the release film, to fixture part resetting and product unloading. Specifically, the feeding device grabs the fixture containing the product from the transfer conveyor belt and places it on the positioning platform. Then, the first linear drive module drives the positioning platform to the station of the fixture disassembly and assembly device. During this process, the adsorption device first adsorbs and fixes the flip cover of the product, so that the flip cover maintains a stable posture in subsequent operations. Then, the fixture disassembly and assembly device disassembles the upper part of the fixture, thereby separating the flip cover from the machine body and providing unobstructed operating space for the film-tearing device. Next, the first linear drive module drives the positioning platform back to the film-tearing station, and the film-tearing device moves to the product... Above the machine body, the edge of the release film is clamped and torn off. Simultaneously, the positioning platform rotates around its axis under the drive of the rotary drive component, allowing the release film to be completely removed during continuous rotation. After tearing, the first linear drive module moves the positioning platform to the fixture disassembly and assembly device. The fixture disassembly and assembly device reinstalls the upper section onto the lower section, and the adsorption device releases the flip cover to reposition it by the upper section. Subsequently, the feeding device picks up the fixture containing the torn product and returns it to the transfer conveyor belt, where the unloading device transfers it to the unloading conveyor belt, thus completing the entire film tearing process. This automated process completely replaces the traditional manual film tearing operation, effectively solving the technical problems of low efficiency and high labor intensity in existing technologies, which make it difficult to control stable production efficiency.

Detailed Implementation

[0050] This invention discloses an automated film-tearing device to solve the technical problems of low efficiency and high labor intensity of manual film tearing in the prior art, which makes it difficult to control the production efficiency stably.

[0051] To enable those skilled in the art to better understand the present invention, the invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are merely some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0052] Please see Figures 1 to 7 An automated film-tearing device provided in this embodiment of the invention includes a frame 1, a first linear drive module 4, a feeding device 3, a transfer conveyor belt 2, a discharging device 10, a discharging conveyor belt 11, a film-tearing device 8, a positioning platform 5, an adsorption device 6, and a fixture disassembly and assembly device 7.

[0053] The transfer conveyor belt 2 is installed on the frame 1, and the transfer conveyor belt 2 is used to transport the jig containing the product to the feeding device 3;

[0054] The feeding device 3 is installed on the frame 1, and the feeding device 3 is used to grab the jigs with products loaded on the transfer conveyor belt 2;

[0055] The first linear drive module 4 is mounted on the frame 1. The first linear drive module 4 is connected to a mounting plate 13. The positioning platform 5 is mounted on the mounting plate 13, and the positioning platform 5 is connected to a rotary drive component 12 mounted on the mounting plate 13. The rotary drive component 12 is used to drive the positioning platform 5 to rotate around its axis. The positioning platform 5 is used to receive a jig containing products transferred from the loading device 3.

[0056] The fixture disassembly and assembly device 7 is installed at the end of the first linear drive module 4. The fixture disassembly and assembly device 7 is used to disassemble and assemble the fixture. It should be noted that the fixture is for positioning a smartwatch product, and it includes an upper part, a lower part, and a spring-loaded latch. The upper part is used to position the flip cover (i.e., the dial cover) of the smartwatch product, and it has a top positioning hole on its top and a side positioning hole on its side. The lower part is used to position the body (i.e., the main body of the watch case) of the smartwatch product. The upper part is detachably mounted to the top of the lower part via the spring-loaded latch. Specifically, the lower part is provided with a spring-loaded latch, which can elastically deform under external force, thereby fastening and fixing the upper part to the lower part. When an unlocking force is applied to the spring-loaded latch, the latch releases the lock on the upper part, allowing the upper part to separate from the lower part. The specific structure of the above-described fixture is prior art. Those skilled in the art should understand that any fixture with the above structure can be applied to the fixture disassembly and assembly device 7 of this embodiment.

[0057] The adsorption device 6 is installed on the mounting plate 13, and the adsorption device 6 is used to adsorb and fix the flip cover of the product.

[0058] The film-tearing device 8 is mounted on the frame 1 and located on one side of the first linear drive module 4. The film-tearing device 8 is used to tear off the release film on the body of the product.

[0059] The feeding device 10 is installed on the frame 1, and the feeding conveyor belt 11 is connected to the discharge end of the transfer conveyor belt 2. The feeding device 10 is located on one side of the discharge end of the transfer conveyor belt 2. The feeding device 10 is used to transfer the fixture containing the film-torn product from the transfer conveyor belt 2 to the feeding conveyor belt 11.

[0060] The automated film-tearing equipment in this embodiment, through the systematic coordination of the feeding device 3, the first linear drive module 4, the positioning platform 5, the fixture disassembly and assembly device 7, the adsorption device 6, the film-tearing device 8, and the unloading device 10, fully realizes the automated operation of the entire process from fixture feeding, separation of the fixture parts, removal of the release film, to fixture part resetting and product unloading. Specifically, the feeding device 3 grabs the fixture with the product loaded on the transfer conveyor belt 2 and places it on the positioning platform 5. Then, the first linear drive module 4 drives the positioning platform 5 to move to the station where the fixture disassembly and assembly device 7 is located. During this process, the adsorption device 6 first adsorbs and fixes the flip cover of the product, so that the flip cover maintains a stable posture in subsequent operations. Then, the fixture disassembly and assembly device 7 disassembles the upper part of the fixture, thereby separating the flip cover from the machine body and providing unobstructed operating space for the film-tearing device 8. Next, the first linear drive module 4 drives the positioning platform 5 back to the film-tearing station, and the film-tearing device 8 moves to the product machine. Above the product, the edge of the release film is clamped and torn off. Simultaneously, the positioning platform 5 rotates around its axis under the drive of the rotary drive 12, so that the release film is completely torn off during continuous rotation. After the film is torn off, the first linear drive module 4 moves the positioning platform 5 to the fixture disassembly and assembly device 7. The fixture disassembly and assembly device 7 reinstalls the upper part to the lower part, and the adsorption device 6 releases the flip cover so that it is repositioned by the upper part. Then, the feeding device 3 picks up the fixture containing the torn product and returns it to the transfer conveyor belt 2, and the unloading device 10 transfers it to the unloading conveyor belt 11, thus completing the entire film tearing process. The above automated process completely replaces the traditional manual film tearing operation, effectively solving the technical problem that the low efficiency and high labor intensity of manual film tearing make it difficult to control the production efficiency stably.

[0061] Furthermore, the film-tearing device 8 in this embodiment includes a six-axis robot 801, and the execution end of the six-axis robot 801 is connected to a film-tearing assembly 802;

[0062] The film-peeling assembly 802 includes a mounting frame 803, a vacuum nozzle 807, and a film-peeling clamp 806 for cooperating with the vacuum nozzle 807 to clamp and fix the release film.

[0063] The vacuum nozzle 807 is connected to the mounting bracket 803;

[0064] A first horizontal cylinder 804 is connected to the mounting bracket 803. The first horizontal cylinder 804 is connected to a first lifting cylinder 805. The first lifting cylinder 805 is connected to the film-tearing clamp 806. The first horizontal cylinder 804 is used to drive the film-tearing clamp 806 to move towards the vacuum nozzle 807. The first lifting cylinder 805 is used to drive the film-tearing clamp 806 to rise and fall.

[0065] It should be noted that in the above design, through the multi-degree-of-freedom motion of the six-axis robot 801, the film-tearing assembly 802 can approach the release film on the surface of the product body in any posture, adapting to the film-tearing angle requirements of different product models; the vacuum nozzle 807 is used to adsorb the surface of the release film, and the first horizontal cylinder 804 drives the film-tearing clamp 806 to move towards the vacuum nozzle 807, cooperating with the vacuum nozzle 807 to clamp and fix the edge of the release film, and cooperating with the movement of the six-axis robot 801 to tear the release film into an initial opening. The above structure achieves reliable clamping and controllable tearing of the release film edge, which facilitates the subsequent positioning platform 5 to smoothly tear off the entire annular release film when rotating.

[0066] Furthermore, in this embodiment, a vision inspection device 14 is also installed on the mounting plate 13. The vision inspection device 14 is specifically used to detect the position of the release film on the product, thereby providing precise position guidance for the six-axis robot 801 and ensuring that the film-tearing assembly 802 can accurately clamp the release film.

[0067] Furthermore, in this embodiment, a pressing device 15 is also installed on the mounting plate 13, which is used to press the product on the fixture.

[0068] The pressing device 15 includes a second horizontal cylinder, a third horizontal cylinder, a second lifting cylinder, and a pressing plate 1501;

[0069] The second horizontal cylinder is mounted on the mounting plate 13. The third horizontal cylinder is connected to the second horizontal cylinder. The second horizontal cylinder is used to drive the third horizontal cylinder to move towards the positioning platform 5. The second lifting cylinder is connected to the third horizontal cylinder. The third horizontal cylinder is used to drive the second lifting cylinder to move towards the positioning platform 5. The pressure plate 1501 is connected to the second lifting cylinder. The second lifting cylinder is used to drive the pressure plate 1501 to descend to press against the product.

[0070] It should be noted that, through the above design, when the film-tearing operation is performed, the second and third horizontal cylinders act sequentially to move the pressure plate 1501 above the product body. The second lifting cylinder drives the pressure plate 1501 to descend and press against the product body, thereby applying a stable clamping force to the product body during the film-tearing process. This prevents the product body from shifting or tilting in the fixture due to the film-tearing tension, ensuring the stability of the product posture during the film-tearing process and further improving the film-tearing accuracy and product safety.

[0071] Furthermore, the positioning platform 5 in this embodiment includes a base, a clamping cylinder, and a placement plate 501;

[0072] The base is connected to the rotary drive 12. The clamping cylinder and the placement plate 501 are both mounted on the base. The clamping cylinder is connected to a pair of clamping plates 502. The clamping cylinder is used to drive the pair of clamping plates 502 to move closer to each other to clamp and fix the fixture placed on the placement plate 501.

[0073] It should be noted that, through the above design, after the feeding device 3 places the fixture containing the product on the placement plate 501, the clamping cylinder drives a pair of clamping plates 502 to move closer to each other and clamp and fix the fixture. This ensures that the relative position between the fixture and the positioning platform 5 remains unchanged during the subsequent rotational film tearing and transfer process, preventing the fixture from shaking or shifting under the drive of the rotational drive 12. This ensures that the film tearing device 8 can accurately act on the release film on the product body, improving the repeatability and positioning accuracy of the film tearing action.

[0074] Furthermore, the adsorption device 6 in this embodiment includes a second linear drive module, a lifting drive module, and a rotation drive module;

[0075] The second linear drive module is mounted on the mounting plate 13. The lifting drive module is connected to the second linear drive module. The second linear drive module is used to drive the lifting drive module to move along the direction of the positioning platform 5. The rotary drive module is connected to the lifting drive module. The lifting drive module is used to drive the rotary drive module to move up and down. The rotary drive module is connected to an adsorption plate 601. The rotary drive module is used to drive the adsorption plate 601 to rotate.

[0076] It should be noted that, through the above design, the second linear drive module can horizontally move the adsorption plate 601 above the flip cover, the lifting drive module drives the adsorption plate 601 to descend and adhere to the surface of the flip cover for adsorption, and the rotation drive module can drive the adsorption plate 601 to rotate after the flip cover is adsorbed and fixed, so as to rotate the flip cover to a predetermined angle, which facilitates the jig disassembly and assembly device 7 to pick up and put the upper part from a specific position, or to assist the flip cover to reset at a specific angle after the film is peeled off. The above-mentioned multi-degree-of-freedom adsorption device 6 can flexibly adapt to the flip cover shape and disassembly and assembly angle requirements of different product specifications, improving the versatility and operational flexibility of the equipment.

[0077] Furthermore, the fixture disassembly and assembly device 7 in this embodiment includes a base 701, a first lifting drive 714, a mounting base 702, an upper clamping assembly, an unlocking assembly, and a pair of horizontal clamping assemblies.

[0078] The base 701 is mounted on the frame 1, the first lifting drive 714 is mounted on the base 701, the mounting seat 702 is connected to the first lifting drive 714, the first lifting drive 714 is used to drive the mounting seat 702 to move in the vertical direction, and the horizontal clamping assembly, the upper pressing assembly and the unlocking assembly are all mounted on the mounting seat 702.

[0079] The pair of horizontal clamping components are used to clamp and fix the opposite sides of the upper part, the upper pressing component is used to press against the top of the upper part, and the unlocking component is used to trigger the elastic lock to unlock the upper part and the lower part.

[0080] It should be noted that, through the above design, when the positioning platform 5 carrying the fixture moves to the station where the fixture disassembly and assembly device 7 is located, the first lifting drive component 714 drives the mounting base 702 to descend to a suitable height. A pair of horizontal clamping components clamp and fix the upper part of the fixture from both sides, and the upper pressing component presses against the top of the upper part from above. The unlocking component triggers the elastic lock to unlock the upper part from the lower part. Under the above multiple clamping and positioning actions, the upper part is firmly held. After unlocking, the first lifting drive component 714 drives the mounting base 702 to rise, which can remove the upper part together with the flip cover from the lower part, realizing the stable separation of the upper part and the lower part. This creates conditions for the subsequent film-tearing operation. At the same time, after the film is torn off, the upper part can be accurately reinstalled onto the lower part, ensuring the complete reset of the fixture.

[0081] Specifically, the horizontal clamping assembly includes a fourth horizontal cylinder 703 and a gripper 704; the fourth horizontal cylinder 703 is mounted on the mounting base 702, and the gripper 704 is connected to the fourth horizontal cylinder 703. The fourth horizontal cylinder 703 is used to drive the gripper 704 to move horizontally so that it moves closer to or away from the gripper 704 in another horizontal clamping assembly; the inner side of the gripper 704 is provided with a first positioning pin 705 for inserting into the side positioning hole of the upper part;

[0082] The upper clamping assembly includes a clamping part 706; the bottom surface of the clamping part 706 is provided with a downwardly extending second positioning pin 707, which is used to insert into the top positioning hole of the upper part.

[0083] The unlocking assembly includes a third lifting cylinder 712 and an unlocking pressure column 713; the third lifting cylinder 712 is mounted on the mounting base 702, and the unlocking pressure column 713 is connected to the third lifting cylinder 712. The third lifting cylinder 712 is used to drive the unlocking pressure column 713 to move vertically to abut against the elastic latch, thereby unlocking the elastic latch.

[0084] It should be noted that, through the above design, the insertion and engagement of the first positioning pin 705 with the side positioning hole and the insertion and engagement of the second positioning pin 707 with the top positioning hole achieves double precise positioning of the upper part, ensuring that the upper part will not shift position during disassembly and installation; the unlocking pressure column 713 moves vertically under the drive of the lifting cylinder, and unlocks by abutting the elastic lock. The action is direct and reliable, and will not damage other parts of the fixture, ensuring the accuracy and repeatability of the fixture disassembly and assembly process.

[0085] Furthermore, a visual alignment device 9 is also installed on the frame 1 in this embodiment;

[0086] The visual alignment device 9 includes a detection camera and a detection light source.

[0087] It should be noted that, through the above design, after the release film is removed by the film-tearing device 8, the adsorption device 6 adsorbs and fixes the flip cover. The first linear drive module 4 drives the positioning platform 5 to move again to the work station where the fixture disassembly and assembly device 7 is located. At this time, the vision alignment device 9 performs image acquisition and recognition on the installation position of the lower part of the fixture for installing the upper part, and at the same time detects the relative position of the flip cover and the upper part, thereby guiding the flip cover to align with the upper part in a precise posture. Then, the fixture disassembly and assembly device 7 reinstalls the upper part to the lower part, and then the adsorption device 6 places the product flip cover on the upper part.

[0088] The guiding function of the aforementioned visual alignment device 9 effectively compensates for the slight positional shift that may occur during the adsorption and rotation of the flip cover, ensuring that the flip cover can be accurately placed in the upper part. This avoids misalignment between the flip cover and the upper part due to misalignment, ensuring the accuracy and reliability of the fixture reset, thereby guaranteeing the positioning accuracy of the product in the fixture and providing a qualified product posture for subsequent processes.

[0089] Furthermore, the jig disassembly and assembly device 7 in this embodiment also includes a second lifting drive 708 and a pair of light-blocking components;

[0090] The second lifting drive component 708 is mounted on the mounting base 702, and the second lifting drive component 708 is connected to a connecting plate 709. A pair of the light-blocking components are mounted on the connecting plate 709.

[0091] The light-blocking assembly includes a fifth horizontal cylinder 710 and a light-blocking plate 711;

[0092] The fifth horizontal cylinder 710 is installed on the connecting plate 709. The light-blocking plate 711 is connected to the fifth horizontal cylinder 710. The fifth horizontal cylinder 710 is used to drive the light-blocking plate 711 to move horizontally so that it is close to or away from the light-blocking plate 711 in another light-blocking assembly. The inner side of the light-blocking plate 711 is recessed to form a groove. When the two light-blocking plates 711 are driven to come close to each other and fit together, the two grooves form a through hole that matches the shape of the flip cover of the product.

[0093] It should be noted that, through the above design, when the vision alignment device 9 performs photographic inspection on the product body, the second lifting drive component 708 drives the light-blocking component to descend to a suitable height, and the two fifth horizontal cylinders 710 drive the two light-blocking plates 711 to approach and fit together, so that the through hole is just fitted on the outside of the flip cover, thereby blocking the influence of external stray light on the inspection area. At the same time, the through hole matches the shape of the flip cover, so as not to affect the inspection camera's imaging of the release film on the body. This improves the inspection accuracy and stability of the vision alignment device 9 in complex lighting environments.

[0094] Furthermore, a waste collection box is also installed on the frame 1 in this embodiment;

[0095] The waste collection box is located on one side of the film-tearing device 8 to collect the torn release film.

[0096] It should be noted that, through the above design, the release film torn off the product body surface by the film tearing device 8 is directly placed into the waste collection bin, realizing the centralized collection of waste, avoiding the release film being scattered in the work area or contaminating subsequent processes as the product flows, ensuring the cleanliness of the internal environment of the equipment, and also facilitating the operator to clean up waste regularly, thus improving the maintenance convenience of the equipment.

[0097] Furthermore, in this embodiment, the feeding device 3 can be a multi-axis robot, and the unloading device 10 can be a multi-axis robot. Their specific structures are existing technologies, and this embodiment will not elaborate on them further. Designers can make reasonable choices according to actual needs.

[0098] Furthermore, in this embodiment, the rotary drive component 12 can be a servo motor, the linear drive module can be an electric cylinder or a pneumatic cylinder, the rotary drive module can be a servo motor, the lifting drive component is a pneumatic cylinder, and the lifting drive module is a pneumatic cylinder.

[0099] The above is a detailed description of the specific structure of the automated film-tearing device provided by the present invention. The following is a further explanation of the device using a specific workflow:

[0100] First, the fixture containing the product to be peeled is conveyed to the loading station by the transfer conveyor belt 2. The loading device 3 grabs the fixture containing the product from the transfer conveyor belt 2 and places it on the positioning platform 5. The positioning platform 5 is equipped with a clamping cylinder. After the fixture is placed in place, the clamping cylinder drives a pair of clamping plates 502 to move closer together to clamp and fix the fixture, ensuring that the fixture remains stable during subsequent transfer and rotation.

[0101] Next, the first linear drive module 4 drives the mounting plate 13 and the positioning platform 5 mounted on it to move in a straight line, moving the positioning platform 5 to the workstation of the fixture assembly / disassembly device 7. During this process, the adsorption device 6 operates: the second linear drive module moves the adsorption plate 601 horizontally to the top of the product flip cover, and the lifting drive module drives the adsorption plate 601 to descend to fit the surface of the flip cover. The flip cover is adsorbed and fixed by vacuum adsorption, so that the flip cover maintains a stable posture in subsequent operations.

[0102] After the adsorption device 6 adsorbs and fixes the flip cover, the fixture disassembly and assembly device 7 performs the disassembly operation of the upper part of the fixture. The first lifting drive 714 of the fixture disassembly and assembly device 7 drives the mounting base 702 to descend to a suitable height. The fourth horizontal cylinders 703 of a pair of horizontal clamping components drive their respective grippers 704 to move from both sides to the middle. The first positioning pins 705 on the inner side of the grippers 704 are inserted into the positioning holes on the side of the upper part, clamping and fixing the two sides of the upper part. At the same time, the upper pressing component presses against the top of the upper part from above. The second positioning pins 707 on the bottom surface of the pressing part 706 are inserted into the top positioning holes of the upper part, achieving double precise positioning of the upper part. Subsequently, the third lifting cylinder 712 of the unlocking component drives the unlocking pressure column 713 to move vertically. The unlocking pressure column 713 presses down against the elastic lock on the lower part of the fixture, causing the elastic lock to deform elastically and release the lock on the upper part. At this time, the first lifting drive component 714 drives the mounting base 702 to rise. Since the upper part has been firmly held by the horizontal clamping component and the upper pressing component, the upper part will be removed from the lower part when the mounting base 702 rises, so that the product body is completely exposed and provides unobstructed operating space for the film tearing device 8.

[0103] After the upper section is disassembled, the first linear drive module 4 actuates again, driving the positioning platform 5 to move from the fixture disassembly and assembly device 7 back to the film-tearing station. The film-tearing device 8 begins to perform the film-tearing operation: the film-tearing device 8 includes a six-axis robot 801, which drives the film-tearing assembly 802 to move above the product body. The vacuum nozzle 807 of the film-tearing assembly 802 first adsorbs the surface of the release film on the product body. Then, the first horizontal cylinder 804 drives the film-tearing clamp 806 to move towards the vacuum nozzle 807, cooperating with the vacuum nozzle 807 to clamp and fix the edge of the release film, and cooperating with the movement of the six-axis robot 801 to tear an initial opening in the release film.

[0104] After the edge of the release film is torn open, the rotary drive component 12 connected to the positioning platform 5 starts working, driving the positioning platform 5 to rotate at a constant speed around its axis. The fixture and product body mounted on the positioning platform 5 rotate synchronously. During the rotation of the positioning platform 5, the six-axis robot 801 drives the film-tearing assembly 802 to keep the release film clamped and fixed. The release film is gradually and completely peeled off from the surface of the product body during continuous rotation. During the film-tearing process, the pressing device 15 operates synchronously: the second horizontal cylinder and the third horizontal cylinder operate in sequence, moving the pressing plate 1501 above the product body. The second lifting cylinder drives the pressing plate 1501 to descend and press against the product body, thereby applying a stable pressing force to the product body under the action of the film-tearing tension, preventing the product body from shifting or tilting in the fixture.

[0105] After the release film is completely torn off, the film-tearing device 8 transfers the torn release film to the waste collection bin for centralized collection of waste. Subsequently, the first linear drive module 4 drives the positioning platform 5 to the station of the fixture disassembly and assembly device 7 to prepare for the resetting and installation of the fixture components.

[0106] Before the upper part of the fixture is reset, the vision alignment device 9 performs an alignment detection operation. The vision alignment device 9 includes a detection camera and a detection light source. The detection camera, in conjunction with the detection light source, acquires and identifies images of the mounting position of the upper part on the lower part of the fixture, while simultaneously detecting the relative position between the flip cover and the upper part. The control system calculates the relative positional deviation between the flip cover and the upper part based on the detection results of the vision alignment device 9, and accordingly controls the rotation drive module and lifting drive module of the adsorption device 6 to adjust the angle and height of the flip cover, thereby guiding the flip cover to align precisely with the upper part. Subsequently, the fixture disassembly and assembly device 7 reinstalls the upper part onto the lower part, and then the adsorption device 6 releases the flip cover, accurately placing the product flip cover into the upper part, completing the precise reset of the flip cover and the upper part.

[0107] During the aforementioned visual alignment process, the light-blocking components of the fixture assembly / disassembly device 7 operate synchronously: the second lifting drive 708 drives the connecting plate 709 and the light-blocking components mounted on it to descend to a suitable height; the two fifth horizontal cylinders 710 respectively drive the two light-blocking plates 711 to approach and fit together; the grooves on the inner sides of the two light-blocking plates 711 are spliced ​​together to form a through hole that matches the shape of the flip cover; the through hole fits precisely on the outside of the flip cover, thereby blocking the influence of stray light from the outside on the detection area; at the same time, the through hole matches the shape of the flip cover, without affecting the imaging of the lower part installation position and the flip cover by the detection camera, thereby improving the detection accuracy and stability of the visual alignment device 9 in complex lighting environments.

[0108] After the flip cover and upper section have completed their reset, the first linear drive module 4 drives the positioning platform 5 back to the loading station. The clamping cylinder drives a pair of clamping plates 502 to move away from each other, releasing the clamping force on the fixture. The loading device 3 picks up the fixture containing the film-torn product from the positioning platform 5 and places it back onto the transfer conveyor belt 2. The transfer conveyor belt 2 transports the fixture to the discharge end. The unloading device 10 transfers the fixture from the discharge end of the transfer conveyor belt 2 to the unloading conveyor belt 11, which then transports the film-torn product to the subsequent process.

[0109] Thus, the automated film-peeling equipment in this embodiment has completed a full product film-peeling cycle. Under the unified and coordinated control of the control system, each of the above processes is executed automatically in sequence, operating continuously in a cycle. This achieves fully automated film-peeling operations from jig loading, jig clamping and positioning, flip-top adsorption and fixation, separation of parts on the jig, removal of the release film, waste collection, visual alignment guidance, jig part reset, flip-top release and positioning, to product unloading. It completely replaces traditional manual film-peeling operations, effectively improving film-peeling efficiency, reducing labor intensity, and ensuring the stability of film-peeling quality.

[0110] The above provides a detailed description of an automated film-tearing device provided by the present invention. For those skilled in the art, based on the ideas of the embodiments of the present invention, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of the present invention.
