[0026]In summary, this application includes at least one of the following beneficial technical effects: When the film-tearing action is performed, the adsorption film-tearing component is mounted on the moving module, and the peeling action is performed by the moving module, which can move in three directions: X-axis, Y-axis, and Z-axis. Based on the multi-axis linkage spatial composite motion, the optimal peeling angle during manual tearing can be dynamically simulated, so that the vertical upward tearing force originally concentrated on the local area of the button bracket is transformed into a shearing peeling force along the surface of the bracket. This reduces the local stress concentration of the button bracket at the moment of peeling and reduces the risk of deformation and breakage caused by uneven force in one direction. At the same time, the second adsorption component in the adsorption film-tearing component can also ensure stable holding when the button bracket is pressed onto the product.

Abstract
Description
Technical Field
[0001] This application relates to the field of button bracket processing technology, and in particular to a device for removing the release film from a button bracket. Background Technology
[0002] In the manufacturing of consumer electronics, automotive electronics and other products, components such as buttons and touch modules are often fixed by adhesive brackets or foam. When these auxiliary materials are received, their adhesive surfaces are usually covered with a release film (or release liner) to prevent contamination and premature adhesion.
[0003] The prior art relates to a release film separation device, which includes a pre-separation device, comprising: a support mechanism including a support platform for supporting a protective film; the protective film including a laminated film body and a release film; a separation mechanism including a separation element configured to extend from one side of the protective film's pre-separation edge between the film body and the release film to separate the film body and the release film's pre-separation edge; and a film-tearing device configured to completely separate the release film from the film body after the pre-separation edge of the film body and the release film has separated; the film-tearing device includes: a first robot configured to grasp the film body from the support platform and move the protective film to the film-tearing mechanism; and the film-tearing mechanism configured to grasp the release film of the protective film grasped by the first robot and move relative to the first robot to completely separate the release film from the film body.
[0004] Existing film-tearing equipment has difficulty controlling the deformation of the button bracket during the film-tearing operation. In particular, when the release film ear is warped or misaligned, the conventional straight-line film-tearing action is prone to failure to grasp the ear or deformation and damage to the button bracket due to concentrated force. Summary of the Invention
[0005] This application provides a button bracket release film removal device, which can solve the problem that existing film removal devices often cause the film ear to fail to be picked up or the button bracket to be deformed and damaged due to concentrated force when performing the film removal operation.
[0006] The technical solution of this application is as follows: a button bracket release film removal device, used to remove the release film on the button bracket and transfer it to the bonding process, including: A tearing device, comprising a moving module and an adsorption tearing assembly for adsorbing the button bracket and clamping the release film ear, wherein the adsorption tearing assembly is mounted on the moving end of the moving module, and the moving module is configured to drive the adsorption tearing assembly to move along the X, Y and Z axes to move and adjust the adsorption tearing assembly to a preset turning position. After the button bracket is installed, drive the adsorption and peeling film assembly away from the button bracket and peel off the release film along a peeling direction that is obtuse relative to the surface of the button bracket; The translation and flipping assembly includes a flipping clamp and a translation cylinder. The flipping clamp is mounted on the drive shaft of the translation cylinder and is located below the tearing device. The translation cylinder is configured to drive the flipping clamp to move closer to or away from the turning station. The translation and flipping assembly is configured to clamp the button bracket and approach the tearing device in a second posture with the release film facing away from the tearing device until it reaches the turning station. Flip the button bracket and adjust it to the first position where the release film faces the tearing device, so that the adsorption tearing component can clamp the release film ear.
[0007] By adopting the above solution, the traditional method of directly pulling and tearing the release film is changed to first having the release film ear firmly clamped by the adsorption tearing component, and then cooperating with the moving module to drive the adsorption tearing component to perform displacement operations on the X, Y and Z axes at the peeling angle of a human hand. A peeling angle is formed between the release film and the button bracket, so that the tearing force is converted into shear peeling force along the surface of the button bracket. This reduces the deformation or damage to the button bracket caused by uneven force during the film tearing process due to vertical tension in a single direction.
[0008] In one embodiment of this application, the moving module includes an X-axis linear moving module, a Y-axis linear moving module, and a Z-axis linear moving module. The Z-axis linear moving module is fixedly mounted on the moving end of the X-axis linear moving module, the X-axis linear moving module is fixedly mounted on the moving end of the Y-axis linear moving module, and the adsorption and tearing film assembly is disposed on the moving end of the Z-axis linear moving module.
[0009] By adopting the above solution, and by setting up X-axis, Y-axis and Z-axis linear moving modules, the three together construct a three-dimensional Cartesian coordinate system driving platform, which enables the adsorption and film-tearing assembly mounted on the moving end of the Z-axis linear moving module to have three-dimensional spatial movement capabilities. This allows the adsorption and film-tearing assembly to be accurately moved to the preset turning station and the subsequent station where the bracket is pressed onto the product, in order to adapt to the positioning deviation of button brackets of different specifications or different loading positions.
[0010] In one embodiment of this application, the adsorption-tear film assembly includes: A fixing frame is fixedly mounted on the moving end of the Z-axis linear moving module; The first adsorption element is fixedly assembled on the fixed frame and is used to adsorb and fix the button bracket. A clamping component is fixedly assembled on the fixed frame and located on the side of the first adsorption component away from the Z-axis linear moving module, for clamping the release membrane ear.
[0011] By adopting the above scheme, in the initial stage of the action of the clamping component to clamp the release membrane ear, the first adsorption component intervenes first and presses the button bracket onto the flip clamping component. At this time, the first adsorption component and the flip clamping component below form a coordinated upper and lower fixation of the button bracket, which reduces the traction force generated on the bracket at the moment the clamping component contacts and clamps the membrane ear, prevents the button bracket from undergoing slight displacement or local tilting during the clamping process, and ensures the stability of the membrane ear clamping process.
[0012] In one embodiment of this application, the first adsorption element includes: An adsorption cylinder is fixedly mounted on the fixed frame in a vertical direction and located on the side close to the clamping component; An adsorption rod, one end of which is coaxially and fixedly connected to the drive shaft of the adsorption cylinder; The first adsorption nozzle is disposed on the adsorption rod, and the adsorption cylinder is configured to drive the first adsorption nozzle to press down onto the surface of the release film and adsorb, so as to secure the button bracket.
[0013] By adopting the above solution and setting the first suction nozzle, not only does it provide auxiliary clamping and fixing for the button bracket after it is switched from the second posture to the first posture, but it also provides suction and fastening force for the button bracket when it is moved close to the product in the first posture and fastened to the product.
[0014] In one embodiment of this application, the clamping element includes: A gripping cylinder is fixedly mounted on the fixed frame in a vertical direction. A movable claw is fixedly connected to the drive shaft of the gripping cylinder. One end of the movable claw is deflected toward the first adsorption member and extends to form a curved movable gripping part. A fixing strip, one end of which is fixedly mounted on the fixing frame in a vertical direction; A deflecting claw, one end of which is rotatably connected to the other end face of the fixing strip, and the other end of which is deflected toward the first adsorption member and extends to form a curved deflecting gripping part. A pad is provided on one end face of the deflecting claw near the movable claw. The deflecting claw has an arc-shaped surface on the side near the movable claw, and the movable claw has an arc-shaped mating block on the side near the deflecting claw. The arc-shaped mating block is adapted to the shape of the arc-shaped surface.
[0015] By adopting the above scheme, when the gripping cylinder drives the movable claw to extend and retract linearly, the arc-shaped mating block on the side of the movable claw slides and squeezes relative to the arc-shaped surface on the deflection claw, forcing the deflection claw connected to the rotation to deflect, thereby causing the two curved gripping parts at the ends of the movable claw and the deflection claw to come closer to each other. When the deflection claw grips the release film ear, it will first perform an arc-shaped sweeping motion. Once the release film ear is tilted upward, the arc-shaped sweeping deflection claw can press down the tilted ear. Thus, the gripping cylinder can pre-process the tilted ear using only a single linear motion.
[0016] In one embodiment of this application, the flipping clamp includes: A connecting frame is fixedly mounted on the drive shaft of the translation cylinder. The moving end of the X-axis linear moving module is also provided with a Z-axis translation moving module. The translation cylinder is arranged along the Y-axis direction and is mounted on the Z-axis translation moving module. A tilting cylinder, which is fixedly mounted on the connecting frame; A gripper cylinder is fixedly mounted on the drive shaft of the flipping cylinder. The drive shaft of the gripper cylinder is provided with two gripping plates. The two gripping plates move closer or further apart under the drive of the gripper cylinder to grip or release the button bracket.
[0017] By adopting the above scheme, the gripper cylinder drives two gripping plates to horizontally clamp the button bracket from both sides, realizing the basic mechanical fixation of the bracket; the flipping cylinder provides the required rotational freedom of the button bracket in the clamped state; the linear translation stroke of the translation cylinder and the rotational action of the flipping cylinder constitute a spatial compound motion, which enables the button bracket to smoothly and accurately switch between the first posture and the second posture in terms of spatial position and angle, so that the button bracket can maintain a stable predetermined posture at the turning station, so that the adsorption film tearing assembly can perform the film ear gripping operation.
[0018] In one embodiment of this application, the flipping clamp further includes a second adsorption member disposed between the two clamping pieces. The second adsorption member includes an air pump and a second adsorption nozzle. The second adsorption nozzle is connected to the air pump and generates a negative pressure on the surface of the button fixture to assist in adsorbing the button fixture.
[0019] By adopting the above scheme, the clamping plate achieves side mechanical clamping, and the first adsorption nozzle performs auxiliary adsorption on the bottom center area of the button bracket. The mechanical clamping restricts the degree of freedom of the button bracket in the X / Y horizontal direction. At the same time, the vacuum adsorption reduces the vertical deflection or hollow deformation that is easily generated in the center area of the button bracket when subjected to vertical film tearing force, thereby improving the overall rigidity of the button bracket under stress conditions.
[0020] In one embodiment of this application, the second adsorption element further includes: A guide nozzle is coaxially disposed outside the second adsorption nozzle. Multiple guide holes are symmetrically arranged on both sides of the guide nozzle. The guide nozzle is connected to the air pump through a control pipeline. A solenoid valve and a throttle valve are provided on the control pipeline. The clamping plate has multiple flow guide grooves, which are spaced apart along the width direction of the clamping plate.
[0021] By adopting the above scheme, before the action of clamping the membrane ear, the solenoid valve is turned on and the throttle valve restricts the air flow. The guide air nozzle draws air through the guide hole, thereby guiding the airflow above the release film through the membrane ear and assisting in flattening the upturned membrane ear downwards. During the adsorption and transfer of the button bracket, the solenoid valve is turned off, and the air pump's suction capacity is concentrated on the internal second adsorption air nozzle. The second adsorption air nozzle is used to seal and adsorb the workpiece under negative pressure. By switching between two different working modes through timing control, the device achieves the functions of airflow-assisted flattening of the release film membrane ear and anti-detachment fixation of the button bracket.
[0022] In one embodiment of this application, a frame is also included, with a visual inspection camera on one side of the frame, a bracket mounting area on one side of the frame, and a material tray stacking area arranged at intervals along the X-axis on the other side of the frame.
[0023] By adopting the above solution and setting up a vision inspection camera, the positional angle of the button bracket is obtained online, thereby further improving the clamping accuracy of the clamping parts on the release film ear. The translation cylinder not only provides Y-axis displacement for the button bracket when tearing the film, but also enables the device to perform automated feeding, realizing a seamless assembly line operation of automatic feeding, visual positioning correction, film tearing and finished product unloading of the button bracket.
[0024] In one embodiment of this application, the frame includes a vertically arranged and hollow placement rack in the material tray stacking area. The placement rack is provided with an electric lifting platform that moves vertically, and multiple button brackets to be processed are stacked on the electric lifting platform in the vertical direction.
[0025] By adopting the above solution and using the step-by-step lifting control of the electric lifting platform, the stacked button brackets are exposed layer by layer for grabbing by the translation cylinder, which extends the single loading cycle of the equipment and ensures the continuous operation capability of the automated production line.
[0026] In summary, this application includes at least one of the following beneficial technical effects: When the film-tearing action is performed, the adsorption film-tearing component is mounted on the moving module, and the peeling action is performed by the moving module, which can move in three directions: X-axis, Y-axis, and Z-axis. Based on the multi-axis linkage spatial composite motion, the optimal peeling angle during manual tearing can be dynamically simulated, so that the vertical upward tearing force originally concentrated on the local area of the button bracket is transformed into a shearing peeling force along the surface of the bracket. This reduces the local stress concentration of the button bracket at the moment of peeling and reduces the risk of deformation and breakage caused by uneven force in one direction. At the same time, the second adsorption component in the adsorption film-tearing component can also ensure stable holding when the button bracket is pressed onto the product.
[0027] By setting two clamping plates on both sides of the button bracket and a second adsorption nozzle at the bottom, the lateral clamping force and bottom adsorption force are provided, thereby effectively improving the overall rigidity of the flexible bracket. In addition, a guide nozzle is set coaxially around the second adsorption nozzle. Before tearing the film, the throttle valve limits the flow of air, which, together with the guide groove on the clamping plate, helps to blow the upturned film ear downward without interfering with the mechanical action. When fixation is required, the solenoid valve cuts off the flow, and the vacuum negative pressure is concentrated in the central second adsorption nozzle to form a high-pressure lock. By using a single power source and air distribution, the device can pre-treat the release film ear while improving the stability of the button bracket during clamping.
[0028] Before the gripper moves down to grip the membrane ear, the second suction nozzle presses down first, forming a coordinated clamping action with the flipping gripper below, reducing the traction micro-movements on the support at the moment of contact between the grippers. At the same time, the arc-shaped surface of the deflecting claw and the arc-shaped mating block of the movable claw squeeze and engage with each other, transforming the single linear motion of the gripping cylinder into a composite motion of the deflecting claw sweeping around the axis and contracting to clamp. This sweeping motion enables the deflecting claw not only to have a gripping function, but also to actively press down and clamp the randomly tilted membrane ear, thereby improving the success rate of the membrane ear gripping process.

[0031] The following is in conjunction with the appendix Figures 1-10 The release film removal device for the button bracket provided in this application is described in further detail.
[0032] The button bracket release film removal device provided in this application embodiment is used to remove the release film on the button bracket and transfer it to the bonding process, including a removal device and a translation and flipping assembly. Example
[0033] The tearing device 1 includes a moving module 11 and an adsorption tearing assembly 12 for adsorbing the button bracket and clamping the release film ear. The adsorption tearing assembly 12 is mounted on the moving end of the moving module 11. The moving module 11 is configured to drive the adsorption tearing assembly 12 to move along the X, Y and Z axes to move and adjust the adsorption tearing assembly 12 to a preset turning position. After the button holder is pressed onto the product to be assembled, the adsorption and film-peeling assembly 12 is driven away from the button holder and the release film is peeled off along a peeling direction at an obtuse angle relative to the surface of the button holder.
[0034] In this embodiment, the turning station refers to a preset spatial position located below the tearing device 1 and reachable by the translational flipping component 2. At this position, after the flipping clamping component 21 flips the button bracket to the first posture, the adsorption tearing component 12 descends along the Z-axis to clamp the release film ear.
[0035] The translation and flipping assembly 2 includes a flipping clamping member 21 and a translation cylinder 22. The flipping clamping member 21 is mounted on the drive shaft of the translation cylinder 22 and is located below the tearing device 1. The translation cylinder 22 is configured to drive the flipping clamping member 21 to approach or move away from the turning station. The translation and flipping assembly 2 is configured to clamp the button bracket and approach the tearing device 1 in a second posture with the release film facing away from the tearing device 1 until it reaches the turning station. The button bracket is flipped and adjusted to the first position where the release film faces the tearing device 1, so that the adsorption tearing assembly 12 can clamp the release film ear.
[0036] In this embodiment, the translation cylinder 22 and the flipping cylinder 212 in the flipping clamping component 21 are controlled in a time-series linkage by the main control PLC of the equipment. When the clamping component clamps the film ear and fastens the button bracket to the product, the movement of the moving module 11 is controlled to keep the release film and the button bracket dynamically at a preset peel angle of 100° to 135°, so that the destructive tearing force in the vertical direction is directly converted into shear peeling force along the surface of the substrate, ensuring structural stability.
[0037] The moving module 11 includes an X-axis linear moving module 111, a Y-axis linear moving module 112, and a Z-axis linear moving module 113. The Z-axis linear moving module 113 is fixedly mounted on the moving end of the X-axis linear moving module 111, the X-axis linear moving module 111 is fixedly mounted on the moving end of the Y-axis linear moving module 112, and the adsorption and tearing film assembly 12 is disposed on the moving end of the Z-axis linear moving module 113.
[0038] In this embodiment, the X-axis, Y-axis and Z-axis linear motion module 113 preferably adopts a transmission mechanism in which a servo motor drives a ball screw and a linear guide rail. The specific assembly method is common knowledge to those skilled in the art, so it will not be described in detail here.
[0039] The adsorption and tear film assembly 12 includes: a fixing frame 121, a first adsorption member 122, and a clamping member 123. The fixing frame 121 is fixedly mounted on the moving end of the Z-axis linear moving module 113. The first adsorption member 122 is fixedly mounted on the fixing frame 121 and is used to adsorb and fix the button bracket. The clamping member 123 is fixedly mounted on the fixing frame 121 and is located on the side of the first adsorption member 122 away from the Z-axis linear moving module 113, and is used to clamp the release film ear.
[0040] The first adsorption component 122 includes an adsorption cylinder 1221, an adsorption rod 1222, and a first adsorption nozzle 1223. The adsorption cylinder 1221 is fixedly mounted on the fixing frame 121 in a vertical direction and is located on the side close to the clamping component 123. One end of the adsorption rod 1222 is coaxially fixedly connected to the drive shaft of the adsorption cylinder 1221. The first adsorption nozzle 1223 is disposed on the adsorption rod 1222. The adsorption cylinder 1221 is configured to drive the first adsorption nozzle 1223 to press down onto the surface of the release film and adsorb, so as to fasten the button bracket.
[0041] In this embodiment, the adsorption cylinder 1221 is a pneumatic micro cylinder, and a precision pressure reducing valve is provided in its control air circuit to precisely adjust the output thrust. The bottom contact surface of the first adsorption nozzle 1223 is preferably covered with a flexible buffer antistatic material such as polyurethane or silicone. When the flexible first adsorption nozzle 1223 is pressed down on the edge of the non-functional area of the button bracket, the linear contact area can not only evenly distribute the downward load and avoid local stress concentration of the bracket to produce indentations, but also use elastic deformation to finely adjust and compensate for the thickness tolerance of the material surface.
[0042] The clamping component 123 includes a clamping cylinder 1231, a fixing bar 1234, and a deflecting claw 1235. The clamping cylinder 1231 is fixedly mounted on the fixing frame 121 in a vertical direction. A movable claw 1232 is fixedly connected to the drive shaft of the clamping cylinder 1231. One end of the movable claw 1232 is deflected and extended toward the first adsorption component 122 to form a curved movable clamping part 1233. One end of the fixing bar 1234 is fixedly mounted on the fixing frame 121 in a vertical direction. One end of the deflecting claw 1235 is rotatably connected to the fixing bar 1234. On the other end face of 234, the other end of the deflecting claw 1235 is deflected and extended toward the first adsorption member 122 to form a curved deflecting gripping part 1236. A pad 1237 is provided on one end face of the deflecting claw 1235 near the movable claw 1232. An arc-shaped surface 1238 is provided on the side of the deflecting claw 1235 near the movable claw 1232. An arc-shaped mating block 1239 is provided on the side of the movable claw 1232 near the deflecting claw 1235. The shape of the arc-shaped mating block 1239 is adapted to the arc-shaped surface 1238.
[0043] In this embodiment, the deflection claw 1235 can be rotatably connected to the other end face of the fixing bar 1234 via a hinge, and the pad 1237 is disposed on the other side of the deflection end face away from the hinge, so that the deflection claw 1235 plays a supporting role when gripping the membrane ear.
[0044] The flip clamping component 21 includes: a connecting frame 211, a flip cylinder 212, and a gripper cylinder 213. The moving end of the X-axis linear moving module 111 is also provided with a Z-axis translation moving module 23. The translation cylinder 22 is arranged along the Y-axis direction and is mounted on the Z-axis translation moving module 23. The flip cylinder 212 is fixedly mounted on the connecting frame 211. The gripper cylinder 213 is fixedly mounted on the drive shaft of the flip cylinder 212. Two gripping pieces 2131 are provided on the drive shaft of the gripper cylinder 213. The two gripping pieces 2131 move closer or further away from each other under the drive of the gripper cylinder 213 to grip or release the button bracket.
[0045] In this embodiment, the gripper cylinder 213 is a parallel opening and closing pneumatic finger, and the inner shape of the gripping piece 2131 is similar to the outer contour of the button bracket to achieve seamless mechanical fixation on the side.
[0046] The tilting cylinder 212 is preferably a rack and pinion rotary cylinder to provide precise angular tilting torque.
[0047] The flip clamping member 21 also includes a second adsorption member 214, which is disposed between two clamping pieces 2131. The second adsorption member 214 includes an air pump and a second adsorption nozzle 2141. The second adsorption nozzle 2141 is connected to the air pump and generates negative pressure on the surface of the button fixture to assist in adsorbing the button fixture.
[0048] In this embodiment, the second adsorption nozzle 2141 is a wear-resistant and anti-static vacuum suction cup, which is positioned directly opposite the central geometric area or easily deformable and weak area on the back of the button bracket. In addition to relying on the clamping piece 2131 to rigidly limit the edge of the bracket horizontally, a vacuum is generated by the air pump (the negative pressure value can be -60kPa to -85kPa) to generate a vertical adsorption force to resist the upward bending tendency of the central area of the bracket.
[0049] It also includes a frame, on one side of which is a vision inspection camera 3, on one side of which is a bracket mounting area 5, and on the other side of which is a material tray stacking area 4 arranged at intervals along the X-axis.
[0050] In this embodiment, the visual inspection camera 3 adopts an industrial CCD or CMOS area array camera, and a ring light source can also be set on the frame. The visual inspection camera 3, together with the ring light source, captures the feature contour of the button bracket, calculates the position deviation (X / Y offset and angle θ deviation) through image algorithm, and sends the correction data to the PLC in real time to dynamically correct the grasping coordinates of the moving module.
[0051] The frame includes a vertically arranged and hollow placement rack 6 in the material tray stacking area 4. The placement rack 6 is equipped with an electric lifting platform that moves vertically. Multiple button brackets to be processed are stacked on the electric lifting platform in the vertical direction.
[0052] In this embodiment, the electric lifting platform includes a stepper motor, a lifting platform, a lifting screw, and a material sensing photoelectric sensor. When the top layer of button brackets on the placement rack 6 is picked up and removed, the photoelectric sensor detects that there is no material at the current picking height and immediately sends a signal to the PLC. The PLC controls the stepper motor to drive the screw to rotate precisely, causing the lifting platform to lift upwards by a distance exactly equal to the thickness of a single button bracket (or the thickness of the material tray). This specific structured plane is laid out as a column-type three-dimensional storage, ensuring that the stacked materials can always maintain a uniform standard picking height at the top layer. Example
[0053] Example 2 has a structure that is basically the same as Example 1. The difference is that, in order to further improve the ability to flatten the upturned membrane ear, the second adsorption component 214 also includes a guide air nozzle 2142. The guide air nozzle 2142 is coaxially arranged outside the second adsorption air nozzle 2141. Multiple guide holes 2143 are symmetrically arranged on both sides of the guide air nozzle 2142. The guide air nozzle 2142 is connected to the air pump through a control pipeline. The control pipeline is equipped with a solenoid valve and a throttle valve. Multiple guide grooves 2132 are opened on the clamping plate 2131. The multiple guide grooves 2132 are arranged at intervals along the width direction of the clamping plate 2131.
[0054] In this embodiment, the control pipeline is a three-way pipeline, and the solenoid valve can be a two-position two-way solenoid valve. The specific implementation method for realizing the timing function is as follows: the main vacuum pipe led out from the air pump is connected to a pneumatic three-way connector, and the main channel of the pneumatic three-way connector is directly connected to the central second adsorption nozzle 2141; the side channel of the three-way connector is connected to the two-position two-way solenoid valve and the throttle valve in sequence, and then connected to the external guide nozzle 2142.
[0055] Before clamping the diaphragm ear, the solenoid valve is energized and turned on. After the bypass air passage is restricted by the manually adjusted throttle valve, external air is drawn through the guide hole 2143 and the non-interfering guide groove 2132 on the clamping plate 2131 to form a weak downward fluid guide airflow to help flatten the upturned diaphragm ear. Moreover, due to the presence of the throttle valve, the vacuum level in the main channel will not drop sharply, thus preventing workpiece displacement. When holding the button bracket, the solenoid valve is de-energized to cut off the side flow channel, and the negative pressure suction force of the air source system is concentrated on the second adsorption nozzle 2141 of the main channel, forming a negative pressure vacuum lock on the center of the button bracket. This structure based on a three-way circuit achieves seamless switching between two modes of timing: diaphragm-assisted pneumatic flattening and workpiece anti-pull-out holding, under a single negative pressure power source.
[0056] In summary, by using a three-dimensional high-precision module with a timing coordination of holding / clamping, a spatial dynamic composite motion peeling mechanism, and a mechanical-pneumatic dual-modal coupling holding based on a three-way flow-limiting pipeline, not only is the deformation and fracture of weak button supports under external force reduced, but also the mechanical sweeping guidance and fluid dynamics-guided airflow improve the high fault tolerance rate for defective release films and enhance the stability of the equipment in unmanned production lines.
[0057] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
