Description

Technical Field

[0001] The present invention relates to the technical field of wear resistance detection devices, and particularly to a release film wear resistance detection device and a use method thereof. Background Art

[0002] A release film refers to a film with a distinguishable surface energy. After the release film comes into contact with a specific material under limited conditions, it has no stickiness or slight stickiness. Usually, in order to increase the release force of the plastic film, the plastic film will be subjected to plasma treatment, fluorine treatment, or coating with a silicone release agent on the surface layer of the film material, such as PET, PE, OPP, etc.; so that it can exhibit a very light and stable release force for various different organic pressure-sensitive adhesives (such as hot melt adhesives, acrylic adhesives, and rubber-based pressure-sensitive adhesives). The wear resistance of the release film determines the service life of the release film, and better wear resistance can adapt to a variety of different working environments and intensities.

[0003] For example, the invention with the publication number CN101750275B discloses a release film detection device, which is characterized by including a bracket, a stage, and an actuator. The stage is used to place the release film to be tested, and the actuator is arranged on the aforementioned bracket and can move relative to the aforementioned stage to act on the surface of the release film to be tested. Compared with the prior art, the advantages of the present invention are: using a dedicated device to apply a quantitative force to the surface of the release film instead of manually rubbing back and forth in an indefinite amount, so that the subsequent force measurement results have unity and standardization, and eliminating the influence of human factors on the performance detection results of the release film. The overall structure is simple, easy to manufacture, and easy to operate.

[0004] The above technical solution still has the following problems in the use process:

[0005] When the above technical solution detects the wear resistance of the release film, it reciprocally rubs the release film through the bottom end of each actuator to achieve the detection purpose. However, after the friction of the release film is completed, it is necessary to manually take out the release film and observe the friction marks on its surface, so the detection efficiency is relatively low;

[0006] When observing the friction marks on the surface of the release film, it is necessary to align the release film with the light source so as to clearly observe the friction marks on the surface of the release film. The staff's long-term alignment with the light source affects the staff's eyesight;

[0007] In the above technical solution, the release film is directly reciprocally rubbed through the bottom end of the actuator, the friction is not comprehensive enough, and the friction force cannot be adjusted. Therefore, the wear resistance under different forces cannot be tested, and the wear resistance detection is not comprehensive enough.

[0008] In view of the above problems, the present invention document proposes a release film wear resistance detection device and a use method thereof. Summary of the Invention

[0009] The present invention provides a device for detecting the wear resistance of a release film and a method for using the same, which solves the disadvantages in the prior art that the wear resistance under different forces cannot be tested, and it is necessary to manually observe the friction marks on the surface of the release film, resulting in low detection efficiency.

[0010] The present invention provides the following technical solutions:

[0011] A device for detecting the wear resistance of a release film, comprising: a workbench, a fixing column fixedly connected to the top of the workbench, a rotating disc rotatably sleeved on the outer wall of the fixing column, a placing plate fixedly connected to the top of the fixing column, and a camera fixedly connected to one side of the placing plate;

[0012] The workbench is provided with a hydraulic channel and a sliding groove, and the hydraulic channel is communicated with the sliding groove. A circular groove is provided on the top of the workbench;

[0013] A placing structure, arranged in the rotating disc, for automatically clamping the release film to be detected, facilitating the subsequent all-round friction of the release film;

[0014] A friction structure, arranged on one side of the top of the workbench, for all-round friction of the release film clamped inside the placing structure;

[0015] A photographing structure, arranged in the hydraulic channel, for vertically placing the placing structure, facilitating the subsequent photographing of the frictioned release film by the camera, and the friction structure can be used to drive the photographing structure.

[0016] In a possible design, the placing structure includes a plurality of rotating shafts fixedly connected in the rotating disc, a rotating plate rotatably sleeved on the outer wall of the rotating shaft, two torsion springs sleeved on the outer wall of the rotating shaft, one end of the two torsion springs close to each other is fixedly connected to both sides of the rotating plate respectively, the end of the torsion spring far from the rotating plate is fixedly connected to the rotating disc, a U-shaped plate is fixedly connected to the end of the rotating plate far from the fixing column, a placing rack for placing the release film is rotatably connected inside the U-shaped plate, a first through hole and a placing groove are communicated inside the placing rack, a notch for putting the release film is arranged on one side of the placing rack, and the notch is communicated with the placing groove;

[0017] A pressing ring for clamping the release film is slidably connected in the placement groove. Both sides of the top of the pressing ring are fixedly connected with tension springs, and the top ends of the tension springs are fixedly connected with the storage rack through bumps. Trapezoidal blocks are slidably penetrated through both sides of the storage rack, and one inclined surface of the trapezoidal block is matched with the pressing ring. The release film to be detected is placed into the placement groove from the notch on one side of the storage rack. When the cushion block moves upward, the cushion block extends into the first through hole to preliminarily limit the storage rack to prevent the storage rack from rotating. The cushion block drives the L-shaped plate to move upward. The cooperation between the L-shaped plate and one inclined surface of the trapezoidal block drives the trapezoidal block to be extruded into the placement groove. The other inclined surface of the trapezoidal block is matched with the pressing ring, and at this time, the pressing ring can clamp the release film in the placement groove.

[0018] In a possible design, the friction structure includes a transmission box fixedly connected to one side of the top of the workbench. A bidirectional lead screw is rotatably connected in the transmission box. Two moving plates are slidably connected in the transmission box, and the two moving plates are respectively located on the positive and negative thread sections of the bidirectional lead screw. One ends of the two moving plates are respectively fixedly connected with a cushion block and a connecting block, and the connecting block is located above the cushion block. A first friction disc is arranged at the bottom of the connecting block. The cushion block is slidably matched with the first through hole. The cushion block is slidably connected in the sliding groove. L-shaped plates are fixedly connected to both sides of the cushion block. The L-shaped plates are matched with the other inclined surface of the trapezoidal block. A pressure sensor is fixedly embedded at the top of the cushion block. A second friction disc is rotatably connected in the first friction disc. The motor is started to drive the bidirectional lead screw to rotate. The bidirectional lead screw drives the cushion block and the first friction disc to move towards the middle. The cooperation between the L-shaped plate and the trapezoidal block can clamp the release film in the placement groove. As the first friction disc and the cushion block approach each other, when the first friction disc and the cushion block simultaneously touch the release film, the pressure sensor senses the pressure. The pressure value of the first friction disc on the release film can be detected through the pressure sensor, and thus the wear resistance of the release film can be detected under different pressures.

[0019] In a possible design, the photographing structure includes a first piston plate hermetically and slidably connected inside one end of a hydraulic passage. The top of the first piston plate is fixedly connected to the same first magnet through a plurality of round rods. The bottom of the rotating disk is fixedly connected to a plurality of L-shaped limiting rods corresponding to the storage rack. An iron weight block cooperating with the first magnet is arranged inside the L-shaped limiting rod. The top of the iron weight block is connected to one end of the rotating plate away from the storage rack through a pull rope. A second piston plate is hermetically and slidably connected inside the other end of the hydraulic passage. The top of the second piston plate is fixedly connected to a connecting rod fixedly connected to the bottom of the cushion block. The rotating disk can make the iron weight block rotate synchronously with the U-shaped plate through the L-shaped limiting rod. When the iron weight block is above the first magnet, the first magnet generates a magnetic suction force on the iron weight block. When the cushion block moves upward, it drives the second piston plate to move upward. The first piston plate drives the iron weight block to move downward through the first magnet. The iron weight block pulls the rotating plate and the U-shaped plate to rotate 90° through the pull rope. At this time, the release film in the storage rack is just aligned with the camera, and the camera photographs the friction marks on the surface of the release film.

[0020] In a possible design, a driving motor is fixedly connected inside the connecting block. The output shaft of the driving motor is fixedly connected to a rotating shaft. The bottom end of the rotating shaft rotatably penetrates through the connecting block and is fixedly connected to a second friction disk. And the first friction disk is rotatably sleeved on the outer wall of the rotating shaft. The second friction disk is rotatably connected inside the first friction disk. A first gear is fixedly sleeved on the outer wall of the rotating shaft. Second gears meshing with the first gear are rotatably connected to both sides of the bottom of the connecting block. A toothed ring meshing with the second gear is fixedly connected to the top of the first friction disk. The driving motor drives the rotating shaft and the second friction disk to rotate. The rotating shaft drives the first friction disk to rotate through the cooperation of the first gear, the second gear and the toothed ring. The rotating directions of the first friction disk and the second friction disk are opposite, so that the wear resistance of the release film can be detected more comprehensively.

[0021] In a possible design, an airbag is fixedly connected to the inner wall of the bottom of the circular groove. A lifting disk is slidably connected inside the circular groove. And the bottom of the lifting disk is adhesively connected to the top of the airbag. Springs are fixedly connected to the inner walls of the two mutually separated sides of the circular groove through bumps. And the top ends of the springs are fixedly connected to the bottom of the lifting disk. The top of the lifting disk is fixedly connected to the same arc-shaped cover through a plurality of round rods. And the arc-shaped cover cooperates with the L-shaped limiting rod. An exhaust pipe extending above the workbench is fixedly connected to one side of the airbag. The storage rack drives the release film to rotate onto the arc-shaped cover. When the L-shaped limiting rod rotates, it squeezes the arc-shaped cover and the lifting disk downward. The lifting disk discharges the gas in the airbag into the placement groove through the exhaust pipe and the air outlet groove, so that the release film can be blown out of the placement groove. The staff puts the next release film into the placement groove and continues the next round of detection, with high detection efficiency.

[0022] In a possible design, a relief groove for making way for the exhaust pipe is provided inside the U-shaped plate. An air outlet groove communicating with the placement groove is provided on one side of the placement rack close to the fixed column, and the air outlet groove is matched with the exhaust pipe. When the rotating disk drives the rotating plate, the U-shaped plate and the placement rack to rotate, the relief groove can make way for the exhaust pipe. When the L-shaped limiting rod rotates above the arc-shaped cover, the exhaust pipe is just aligned with the air outlet groove from the air outlet, and then the gas in the airbag is discharged into the placement groove through the exhaust pipe and the air outlet groove, so as to blow the release film out of the placement groove.

[0023] In a possible design, second magnets are fixedly connected to the inner walls of the mutually remote sides of the U-shaped plate, third magnets are fixedly connected to both sides of the placement rack, and the second magnets are matched with the third magnets. A plurality of stoppers for braking the rotating plate are fixedly connected inside the rotating disk. The rotating plate can be reset under the torsion of the torsion spring, and the stopper can limit the rotating plate. In addition, the cooperation of the second magnet and the third magnet can keep the placement rack in a horizontal state, which is convenient for putting the release film into the placement groove and for inserting the first friction disk and the cushion block into the placement groove and the first through hole respectively for friction.

[0024] In a possible design, an electric push rod is fixedly connected to the top of the fixed column. A Z-shaped rod is slidably penetrated through the placement plate, and one end of the Z-shaped rod is fixedly connected to the output shaft of the electric push rod. The other end of the Z-shaped rod is fixedly connected with a suction cup for adsorbing the placement rack. By driving the Z-shaped rod to reciprocate through the electric push rod, the Z-shaped rod can generate adsorption on one side of the placement rack through the suction cup. Then, when the Z-shaped rod reciprocates, it can drive the placement rack to reciprocate and rotate by a certain angle, so that the camera can take pictures of the release film at different angles, and thus a relatively clear picture can be obtained, which is convenient for the later staff to easily detect the wear resistance of the release film through the picture.

[0025] The usage method of the release film wear resistance detection device described above includes the following steps:

[0026] S1. Put the release film to be detected into the placement groove from one side of the placement rack, and drive the rotating disk to rotate through the driving structure (here, the driving structure can be that the rotating motor drives the rotating disk to rotate through the meshing of the bevel gear and the bevel gear ring, which is not limited here). When the placement rack moves between the first friction disk and the cushion block, start the motor to drive the bidirectional lead screw to rotate. The bidirectional lead screw drives the cushion block and the first friction disk to move towards the middle. When the cushion block moves upward, the cushion block extends into the first through hole to preliminarily limit the placement rack to prevent the placement rack from rotating. The cushion block drives the L-shaped plate to move upward. The L-shaped plate cooperates with the inclined surface on one side of the trapezoidal block to squeeze the trapezoidal block into the placement groove. The inclined surface on the other side of the trapezoidal block cooperates with the pressing ring. At this time, the pressing ring can clamp the release film in the placement groove.

[0027] S2. As the first friction disc and the cushion block approach each other, when the first friction disc and the cushion block simultaneously touch the release film, the pressure sensor senses the pressure. The pressure value of the first friction disc on the release film can be detected through the pressure sensor. Furthermore, the wear resistance of the release film can be detected under different pressures. Then, start the drive motor to drive the rotating shaft and the second friction disc to rotate. The rotating shaft drives the first friction disc to rotate through the cooperation of the first gear, the second gear, and the toothed ring. The rotation directions of the first friction disc and the second friction disc are opposite, so that the wear resistance of the release film can be detected more comprehensively.

[0028] S3. After the friction of the release film is completed, the storage rack for the release film rotates above the first magnet. The rotating disc moves the iron-bearing weight above the first magnet through the L-shaped limiting rod corresponding to the storage rack. The first magnet generates a magnetic attraction force on the iron-bearing weight. Then, the bidirectional lead screw rotates again to clamp the next release film. The cushion block drives the second piston plate to move upward through the connecting rod. The first piston plate drives the iron-bearing weight to move downward through the first magnet. The iron-bearing weight drives the rotating plate and the U-shaped plate to rotate 90° through the pull rope. At this time, the release film in the storage rack just aligns with the camera. The side of the release film in the storage rack away from the camera aligns with the external light source. The camera takes pictures of the friction marks on the surface of the release film.

[0029] S4. The electric push rod drives the Z-shaped rod to move reciprocally. The Z-shaped rod can adsorb one side of the storage rack through the suction cup. Then, when the Z-shaped rod moves reciprocally, it can drive the storage rack to rotate reciprocally by a certain angle, so that the camera can take pictures of the release film at different angles, and a clearer picture can be obtained, which is convenient for the later staff to detect the wear resistance of the release film through the picture.

[0030] S5. After the camera finishes taking pictures, the rotating plate and the U-shaped plate reset under the torque of the torsion spring. The storage rack continues to drive the release film to rotate and moves above the circular groove. The L-shaped limiting rod corresponding to the storage rack squeezes the arc-shaped cover and the lifting disc in the circular groove downward during rotation. The lifting disc discharges the gas in the airbag into the placement groove through the exhaust pipe and the air outlet groove, so that the release film can be blown out of the placement groove. The staff puts the next release film into the placement groove and continues the next round of detection, with high detection efficiency.

[0031] It should be understood that the above general description and the following detailed description are only exemplary and do not limit the present invention.

[0032] In the present invention, a bidirectional lead screw is rotatably connected inside the transmission box. Two moving plates are slidably connected inside the transmission box. One end of each of the two moving plates is fixedly connected to a cushion block and a connecting block respectively. A first friction disc is provided at the bottom of the connecting block. L-shaped plates are fixedly connected to both sides of the cushion block. The L-shaped plates are matched with the other inclined surface of the trapezoidal block. A pressure sensor is fixedly embedded at the top of the cushion block. The bidirectional lead screw drives the cushion block and the first friction disc to move towards the middle. The cooperation between the L-shaped plates and the trapezoidal block can clamp the release film in the placement groove. When the first friction disc and the cushion block touch the release film at the same time, the pressure sensor senses the pressure. The pressure sensor can detect the pressure value of the first friction disc on the release film, and thus the wear resistance of the release film can be detected under different pressures;

[0033] In the present invention, a first magnet is fixedly connected to the top of the first piston plate. A plurality of L-shaped limiting rods are fixedly connected to the bottom of the rotating disc. An iron weight is provided inside the L-shaped limiting rod. The top of the iron weight is connected to one end of the rotating plate through a pull rope. The other end of the hydraulic passage is hermetically and slidably connected with a second piston plate. A connecting rod fixedly connected to the bottom of the cushion block is fixedly connected to the top of the second piston plate. The rotating disc can make the iron weight and the U-shaped plate rotate synchronously through the L-shaped limiting rods. The first magnet generates a magnetic attraction force on the iron weight. The cushion block drives the second piston plate to move upward. The first piston plate drives the iron weight to move downward through the first magnet. The iron weight pulls the rotating plate and the U-shaped plate to rotate 90° through the pull rope. At this time, the release film in the storage rack is just aligned with the camera, and the camera takes pictures of the friction marks on the surface of the release film;

[0034] In the present invention, the output shaft of the drive motor is fixedly connected to a rotating shaft. A second friction disc is fixedly connected to the bottom end of the rotating shaft. The first friction disc is rotatably sleeved on the outer wall of the rotating shaft. A first gear is fixedly sleeved on the outer wall of the rotating shaft. Second gears meshing with the first gear are rotatably connected to both sides of the bottom of the connecting block. A toothed ring meshing with the second gear is fixedly connected to the top of the first friction disc. The drive motor drives the rotating shaft and the second friction disc to rotate. The rotating shaft drives the first friction disc to rotate through the cooperation of the first gear, the second gear and the toothed ring. The first friction disc and the second friction disc rotate in opposite directions, and thus the wear resistance of the release film can be detected more comprehensively;

[0035] In the present invention, an airbag is fixedly connected to the inner wall of the bottom of the circular groove. A lifting plate is slidably connected in the circular groove, and the bottom of the lifting plate is adhesively connected to the top of the airbag. An arc-shaped cover is fixedly connected to the top of the lifting plate. One side of the airbag is fixedly connected to an exhaust pipe extending above the workbench; when the L-shaped limiting rod rotates, it squeezes the arc-shaped cover and the lifting plate downward. The lifting plate discharges the gas in the airbag into the placement groove through the exhaust pipe and the air outlet groove, so as to be able to blow the release film out of the placement groove. The staff puts the next release film into the placement groove and continues the next round of detection, with high detection efficiency.

[0036] In the present invention, by driving the cushion block and the first friction disc to approach each other through the bidirectional lead screw, not only can the release film be clamped for later friction, but also the pressure value of the first friction disc on the release film can be detected through the pressure sensor, so as to be able to detect the wear resistance of the release film under different pressures. In addition, when the cushion block moves upward, the U-shaped plate and the placing rack can be rotated by 90°, so that the camera can take pictures of the friction marks on the release film from different angles.

The other end of the Z-shaped rod 50 is fixedly connected with a suction cup 51 for adsorbing the placing rack 8. By driving the Z-shaped rod 50 to reciprocate through the electric push rod 49, the Z-shaped rod 50 can adsorb one side of the placing rack 8 through the suction cup 51. Then, when the Z-shaped rod 50 reciprocates, it can drive the placing rack 8 to rotate reciprocally by a certain angle, so that the camera 37 can take pictures of the release film at different angles, and thus a relatively clear picture can be obtained, which is convenient for the later staff to easily detect the wear resistance of the release film through the picture.

[0075] A method for using a device for detecting the wear resistance of a release film includes the following steps:

[0076] S1. Place the release film to be detected into the placing groove 10 from one side of the placing rack 8, and drive the rotating disk 3 to rotate through the driving structure (here, the driving structure can be that the rotating motor drives the rotating disk 3 to rotate through the meshing of the bevel gear and the bevel gear ring 27, which is not limited here). When the placing rack 8 moves between the first friction disk 21 and the cushion block 17, start the motor to drive the bidirectional lead screw 14 to rotate. The bidirectional lead screw 14 drives the cushion block 17 and the first friction disk 21 to move towards the middle. When the cushion block 17 moves upward, the cushion block 17 extends into the first through hole 9 to preliminarily limit the placing rack 8 to prevent the placing rack 8 from rotating. The cushion block 17 drives the L-shaped plate 18 to move upward. The L-shaped plate 18 cooperates with the inclined surface on one side of the trapezoidal block 12 to squeeze the trapezoidal block 12 into the placing groove 10. The inclined surface on the other side of the trapezoidal block 12 cooperates with the pressing ring 52. At this time, the pressing ring 52 can clamp the release film in the placing groove 10.

[0077] S2. As the first friction disk 21 and the cushion block 17 approach each other, when the first friction disk 21 and the cushion block 17 touch the release film at the same time, the pressure sensor 19 senses the pressure. Through the pressure sensor 19, the pressure value of the first friction disk 21 on the release film can be detected, and thus the wear resistance of the release film can be detected under different pressures. Start the driving motor 24 to drive the rotating shaft 22 and the second friction disk 23 to rotate. The rotating shaft 22 drives the first friction disk 21 to rotate through the cooperation of the first gear 25, the second gear 26 and the gear ring 27. The rotating directions of the first friction disk 21 and the second friction disk 23 are opposite, so as to more comprehensively detect the wear resistance of the release film.

[0078] S3. After the friction on the release film ends, the storage rack 8 for the release film rotates above the first magnet 30. The rotating disk 3 moves the iron weight 32 above the first magnet 30 through the L-shaped limiting rod 31 corresponding to the storage rack 8. The first magnet 30 generates a magnetic attraction force on the iron weight 32. Then, the bidirectional lead screw 14 rotates again to clamp the next release film. The spacer block 17 drives the second piston plate 34 to move upward through the connecting rod 35. The first piston plate 29 drives the iron weight 32 to move downward through the first magnet 30. The iron weight 32 drives the rotating plate 5 and the U-shaped plate 7 to rotate 90° through the pull rope 33. At this time, the release film in the storage rack 8 is just aligned with the camera 37. The side of the release film in the storage rack 8 away from the camera 37 is aligned with the external light source. The camera 37 takes pictures of the friction marks on the surface of the release film.

[0079] S4. The electric push rod 49 drives the Z-shaped rod 50 to reciprocate. The Z-shaped rod 50 can adsorb one side of the storage rack 8 through the suction cup 51. Then, when the Z-shaped rod 50 reciprocates, it can drive the storage rack 8 to reciprocate and rotate by a certain angle, so that the camera 37 can take pictures of the release film at different angles, and thus a clearer picture can be obtained, which is convenient for the later staff to detect the wear resistance of the release film through the picture.

[0080] S5. After the camera 37 finishes taking pictures, the rotating plate 5 and the U-shaped plate 7 reset under the torsion force of the torsion spring 6. The storage rack 8 continues to drive the release film to rotate and moves above the circular groove. The L-shaped limiting rod 31 corresponding to the storage rack 8 squeezes the arc-shaped cover 40 and the lifting disk 39 downward when rotating. The lifting disk 39 discharges the gas in the airbag 42 into the placement groove 10 through the exhaust pipe 43 and the air outlet groove 48, and then can blow the release film out of the placement groove 10. The staff puts the next release film into the placement groove 10 to continue the next round of detection, and the detection efficiency is high.

[0081] However, as is well known to those skilled in the art, the working principles and wiring methods of the electric push rod 49, the camera 37, the drive motor 24, and the pressure sensor 19 are common knowledge, and they all belong to conventional means or well-known common sense, so they will not be elaborated here. Those skilled in the art can make any selection according to their needs or convenience.

When the holding rack moves to between the first friction disk and the pad, start the motor to drive the bidirectional screw to rotate, and the bidirectional screw drives the pad and the first friction disk to move toward the middle. When the pad moves up, the pad extends into the first through hole to preliminarily limit the holding rack to prevent the holding rack from rotating. The pad drives the L-shaped plate to move up, and the L-shaped plate cooperates with the inclined surface on one side of the trapezoidal block to squeeze the trapezoidal block into the placement groove. The inclined surface on the other side of the trapezoidal block cooperates with the pressure ring. At this time, the pressure ring can clamp the release film in the placement groove; S2. As the first friction disc and the pad block approach each other, when the first friction disc and the pad block touch the release film at the same time, the pressure sensor senses the pressure. The pressure value of the first friction disc on the release film can be detected by the pressure sensor, so that the wear resistance of the release film can be tested under different pressures. The driving motor is started to drive the rotating shaft and the second friction disc to rotate. The rotating shaft drives the first friction disc to rotate through the cooperation of the first gear, the second gear and the gear ring. The first friction disc and the second friction disc rotate in opposite directions, so that the wear resistance of the release film can be tested more comprehensively. S3. When the friction of the release film is finished, the holding rack for the release film rotates to the top of the first magnet, and the rotating disk moves the iron load-bearing block to the top of the first magnet through the L-shaped limiting rod corresponding to the holding rack. The first magnet generates magnetic attraction on the iron load-bearing block, and then the bidirectional screw rotates again to clamp the next release film. The cushion block drives the second piston plate to move up through the connecting rod, and the first piston plate drives the iron load-bearing block to move down through the first magnet. The iron load-bearing block pulls the rotating plate and the U-shaped plate to rotate 90° through the pull rope. At this time, the release film in the holding rack is just aligned with the camera, and the side of the release film in the holding rack away from the camera is aligned with the external light source, and the friction marks on the surface of the release film are photographed by the camera; S4. Drive the Z-shaped rod to reciprocate through the electric push rod. The Z-shaped rod can adsorb one side of the storage rack through the suction cup. Then, when the Z-shaped rod reciprocates, it can drive the storage rack to rotate reciprocally by a certain angle, so that the camera can take pictures of the release film at different angles, and thus a relatively clear picture can be obtained, which is convenient for the later staff to detect the wear resistance of the release film through the picture; S5. After the camera finishes taking pictures, the rotating plate and the U-shaped plate reset under the torsion of the torsion spring. The storage rack continues to drive the release film to rotate and moves above the circular groove. The L-shaped limiting rod corresponding to the storage rack squeezes the arc-shaped cover and the lifting disc in the circular groove downward when rotating. The lifting disc discharges the gas in the airbag into the placement groove through the exhaust pipe and the air outlet groove, and then the release film can be blown out of the placement groove. The staff puts the next release film into the placement groove and continues the next round of detection.
