[0027] The following detailed description, in conjunction with the accompanying drawings, will further illustrate this application. Detailed Implementation

[0028] To better understand the above-mentioned objectives, features, and advantages of the embodiments of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the features in the embodiments of this application can be combined with each other.

[0029] The following description sets forth numerous specific details to provide a thorough understanding of the embodiments of this utility model. The described embodiments are only a portion, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of the embodiments of this utility model.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which embodiments of this invention pertain. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention.

[0031] The present application will be specifically described below through specific embodiments.

[0032] Please see Figures 1 to 5 This application provides a release paper tearing device 100, including a worktable 10, an adsorption mechanism 20, a rotation mechanism 30, and an execution mechanism 40. The worktable 10 includes a support plate 11 for supporting a workpiece with release paper, and the support plate 11 has a through groove 111. The adsorption mechanism 20 includes a vacuum nozzle 21 and a vacuum generator 22, the vacuum generator 22 being connected to the vacuum nozzle 21. The vacuum nozzle 21 passes through the through groove 111 and protrudes from the support plate 11, away from the surface of the adsorption mechanism 20. The rotation mechanism 30 includes a fixing member 31 and a bearing base 36, located on the same side of the support plate 11. The fixing member 31 is used to fix the vacuum nozzle 21 and is rotatably connected to the bearing base 36. The execution mechanism 40 is located on the side of the fixing member 31 away from the support plate 11. The execution mechanism 40 is used to push the fixing member 31 to make the vacuum nozzle 21 contact and adsorb the release paper.

[0033] In this embodiment, there are four vacuum nozzles 21, each equipped with a vacuum generator 22, which enhances the suction force of the adsorption mechanism 20, prevents vacuum breakage during film removal, and ensures stable operation of the device. This is just an example; this application does not impose any special limitation on the number of vacuum nozzles 21, and the number of vacuum nozzles 21 can be designed according to actual needs.

[0034] In some embodiments, a support platform 112 is provided on the surface of the support plate 11 facing away from the adsorption mechanism 20, and a positioning element 113 is provided on the surface of the support platform 112 facing away from the support plate 11. The support platform 112 has a through hole 114, which communicates with a through groove 111 to expose the through groove 111. The positioning element 113 is arranged around the through hole 114. The support platform 112 is used to place the workpiece with release paper, and the positioning element 113 is used to engage with the edge of the workpiece to fix the workpiece to the support platform 112, reducing the probability of the workpiece moving during the process of tearing the release paper.

[0035] In this embodiment, the support platform 112 can be made of flexible materials such as thermoplastic polyurethane elastomer, which can prevent damage to the workpiece. There are five positioning elements 113, distributed around the through hole 114, which facilitates more stable fixation of the workpiece. This is just an example; the application does not impose a specific limitation on the number of positioning elements 113. The positioning elements 113 can be designed and distributed according to the shape and size of the workpiece.

[0036] In some embodiments, the rotating mechanism 30 further includes a limiting member 33, which passes through and is fixed to the side of the fixing member 31 facing the actuator 40. The limiting member 33 is configured to abut against the actuator 40 when the fixing member 31 rotates to limit the rotation angle of the fixing member 31, thereby reducing equipment malfunctions such as interference with the movement of the actuator 40 due to excessive rotation of the fixing member 31. In this embodiment, there are two limiting members 33, which can more effectively limit the rotation angle and amplitude of the fixing member 31. This is just an example, and this application does not impose any special limitation on the number of limiting members 33.

[0037] In some embodiments, the rotating mechanism 30 further includes an elastic member 35, which abuts against the fixing member 31 and the support plate 11. The elastic member 35 abuts against the fixing member 31 and the support plate 11, causing the elastic member 35 to be in a compressed state and storing elastic potential energy. When the fixing member 31 loses the force of the actuator 40, the elastic member 35 can provide a thrust to the fixing member 31 in the direction of the actuator 40.

[0038] In some embodiments, the rotating mechanism 30 further includes a guide shaft 34, which is fixedly connected to the fixing member 31 and movably passes through the support plate 11. An elastic member 35 is sleeved on the guide shaft 34. The guide shaft 34 guides the elastic member 35, allowing its opposite ends to abut against the fixing member 31 and the support plate 11. Simultaneously, the guide shaft 34 also limits the rotation angle of the fixing member 31.

[0039] In some embodiments, the fixing member 31 includes a first fixing block 311 and a second fixing block 312, which are connected and form a step between them. The first fixing block 311 protrudes from the through slot 111, and the second fixing block 312 is fixedly connected to the guide shaft 34. The stepped design of the fixing member 31 provides suitable space for the elastic member 35 and the guide shaft 34 to rotate with the fixing member 31, reducing the probability that the space between the fixing member 31 and the support plate 11 is insufficient for the elastic member 35 and the guide shaft 34 to move. A limiting member 33 is detachably connected to the second fixing block 312, and a portion of the limiting member 33 protrudes from the surface of the second fixing block 312 facing the actuator 40.

[0040] In some embodiments, the rotating mechanism 30 further includes a rotating shaft 32, which is rotatably connected to the bearing base 36 and fixedly connected to the fixing member 31. This arrangement allows the fixing member 31 to rotate relative to the bearing base 36 around the rotating shaft 32. In this embodiment, one end of the rotating shaft 32 is located within the first fixing block 311, and the opposite end of the rotating shaft 32 protrudes from the first fixing block 311. The rotating shaft 32 protruding from the first fixing block 311 is rotatably connected to the bearing base 36.

[0041] In some embodiments, the rotating mechanism 30 further includes a stop screw 37, which passes through the first fixed block 311 and engages with the rotating shaft 32, so that the rotating shaft 32 located in the first fixed block 311 does not rotate relative to the first fixed block 311.

[0042] In some embodiments, the rotating mechanism 30 further includes a bushing 38 and a fastener 39, which are located on the same side of the support plate 11 as the actuator 40. The bushing 38 is embedded in the bearing base 36 and sleeved on the rotating shaft 32. The rotating shaft 32, which protrudes from the first fixing block 311, and the bearing base 36 are tightly fixed by the fastener 39, and the bushing 38 provides lubrication for the rotating shaft 32 during rotation relative to the bearing base 36.

[0043] In some embodiments, the actuator 40 includes a cylinder 41 for abutting against the fixing member 31. The cylinder 41 includes a cylinder body 411 and a piston rod 412, which is movably inserted into the cylinder body 411 and reciprocates. When the piston rod 412 is in the extended state, it can abut against the fixing member 31 to position the vacuum nozzle 21 on the fixing member 31 parallel to the support plate 11.

[0044] In some embodiments, the actuator 40 further includes a support base 42, which is located on the same side of the support plate 11 as the rotating mechanism 30, and the cylinder 41 is located on the surface of the support base 42, which is used to support the cylinder 41.

[0045] In some embodiments, the actuator 40 further includes a sensor 43, and the cylinder 41 further includes a piston. The piston is fixedly connected to the piston rod 412, and the piston rod 412 drives the piston to reciprocate within the cylinder body 411. The sensor 43 may be disposed on the outer wall of the cylinder 41, and the sensor 43 is used to monitor the position of the piston in the cylinder 41 to achieve precise control and adjustment of the positions of the piston and the piston rod 412.

[0046] In some embodiments, the release liner device 100 further includes a pressure gauge 50 connected to a vacuum generator 22. The pressure gauge 50 is used to adjust and display the vacuum value provided by the vacuum generator 22. If the value of the pressure gauge 50 does not reach the preset value, the release liner device 100 will not operate, thus providing a systemic foolproof function.

[0047] In some embodiments, the release paper tearing device 100 further includes a solenoid valve 60 connected to the cylinder 41. The solenoid valve 60 controls the time and distance of the extension or retraction movement of the piston rod 412 of the cylinder 41, thereby driving the vacuum nozzle 21 on the fixing member 31 to move. In some embodiments, a bearing base 36 is mounted on the surface of the solenoid valve 60.

[0048] In some embodiments, the release liner device 100 further includes a control mechanism 70, which is electrically connected to the solenoid valve 60 and the sensor 43. The control mechanism 70 controls the solenoid valve 60 and the sensor 43, generates control information, and transmits the control information to the solenoid valve 60 and the sensor 43. Since the solenoid valve 60 can control the extension or retraction time of the piston rod 412 of the cylinder 41, and the sensor 43 can monitor the position of the piston in the cylinder 41, the control mechanism 70 can be used to control the operating time of the actuator 40, that is, effectively control the film-tearing action time of the release liner device 100 after the vacuum degree reaches a preset value. In this embodiment, the control mechanism 70 can be a programmable logic controller.

[0049] In some embodiments, the workbench 10 further includes a base plate 14 disposed opposite to the support plate 11, a first support frame 12 disposed opposite to the support plate 11, and a second support frame 13 disposed opposite to the support plate 11. The support plate 11, the first support frame 12, the second support frame 13, and the base plate 14 are arranged to form a closed hexahedral box structure.

[0050] In some embodiments, the first support frame 12 is provided with a first button 81, which is used to control the vacuum generator 22 to turn on or off. The second support frame 13 is provided with a second button 82 and a third button 83, which can reset the cylinder 41 by pressing the second button 82 and the third button 83 simultaneously.

[0051] Working principle of the release paper tearing device 100: In the initial state, the piston rod 412 of the cylinder 41 is extended, and the piston rod 412 abuts against the fixing member 31, so that the vacuum suction nozzle 21 on the fixing member 31 is in a position parallel to the support plate 11, and the elastic member 35 abuts between the fixing member 31 and the support plate 11. After the workpiece with release paper is placed on the positioning member 113, the button of the vacuum generator 22 is pressed, so that the vacuum suction nozzle 21 sucks up the release paper. Subsequently, the piston rod 412 of the cylinder 41 retracts, and the piston rod 412 leaves the surface of the fixing member 31. After the fixing member 31 loses the force of the piston rod 412, on the one hand, due to its own weight, the fixing member 31 rotates in the direction of the cylinder 41. On the other hand, the elastic member 35 gives the fixing member 31 a pushing force in the direction of the cylinder 41, so that the fixing member 31 rotates around the rotating shaft 32 in the direction of the cylinder 41. Since the vacuum nozzle 21 is fixedly connected to the fixing member 31, the vacuum nozzle 21 also rotates towards the cylinder 41, peeling the release paper from the workpiece during the rotation. After the release paper is peeled off, the workpiece can be picked up by a robot or manually. Press the first button 81 of the vacuum generator 22 to turn off the vacuum generator 22. The vacuum nozzle 21 no longer generates suction, and the release paper separates from the vacuum nozzle 21. At this time, the release paper can be placed in the designated position by a robot or manually. Then, press the second button 82 and the third button 83 simultaneously with both hands to reset the cylinder 41.

[0052] The above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions to the technical solutions of this application should not depart from the spirit and scope of the technical solutions of this application.
