Description

Technical Field

[0001] The present invention relates to the technical field of feeding devices, and in particular to an operating panel sheet feeding device. Background Art

[0002] The operating panel sheet is a thin and soft sheet made of plastic, adhesive, rubber or other materials. In related technologies, a suction cup is usually used to grab the film. However, in the process of the suction cup grabbing the film, there is a situation where at least two layers of film are grabbed at one time. Therefore, it is necessary to separate the at least two layers of film grabbed by the suction cup to meet actual production needs.

[0003] A Chinese patent document with authorization publication number CN114056934B discloses a dual-suction cup mechanism for a loader. The mechanism includes a support frame, a guide rail assembly, a first suction cup device, a second suction cup device, and a conveyor. The first and second suction cup devices move along the guide rail assembly under the action of the conveyor. The second suction cup device is provided with a first-stage telescopic mechanism. The first suction cup device is provided with a two-stage telescopic mechanism. The two-stage telescopic mechanism creates a height difference between the first suction cup device and the second suction cup device, allowing the first suction cup device to pass through the second suction cup device and operate simultaneously in a different area from the first suction cup device. The two-stage telescopic mechanism includes a first telescopic assembly and a second telescopic assembly, with the second telescopic assembly connected below the first telescopic assembly.

[0004] When existing suction cup gripping devices separate at least two layers of film, they usually use air blowing or brushing to achieve this. When the two layers of film are tightly attached and the side close to the brush is flush, there is no gap between the two layers of film, so they cannot be separated by air blowing. And because the edges are flush, the brush cannot exert a large peeling force on the film below, so the brush cannot guarantee that the two layers of film can be effectively separated. Summary of the Invention

[0005] The present invention provides an operation panel sheet material feeding device, aiming to solve the problem in the related art that it is difficult to separate two layers of thin films.

[0006] The invention relates to an operation panel sheet material feeding device, comprising a workbench, a lifting platform capable of rising and falling relative to the workbench, a suction cup assembly arranged above the lifting platform, a blowing assembly arranged in front of the lifting platform and a brush member arranged on the right side of the lifting platform, a fixing assembly for pressing the sheet material on the lifting platform is arranged on the right side of the lifting platform, the lifting platform comprises a left support plate, a right support plate and a driving assembly, the left support plate and the right support plate are hinged at one side close to each other, the driving assembly comprises two lifting ends respectively connected to the bottom of the left support plate and the right support plate, the suction cup assembly comprises a suction cup 1, a suction cup 2 and Suction cup three, and distributed from left to right, the sheets are neatly stacked on the lifting platform, then the left support plate and the right support plate rise synchronously, suction cup one descends and presses on the left end of the sheet, the left support plate stops lifting, the right support plate tilts downward, the right end of the sheet spreads out, and the brush part is above the right end of the sheet, suction cup two and suction cup three descend and stick to the inclined part of the sheet, then, suction cup two and suction cup three rise to the same height as suction cup one, after which the fixed component presses the sheet on the lifting platform, finally, suction cup one, suction cup two and suction cup three rise at the same time and transport the sheet to the processing line.

[0007] The effect is: by using suction cup one to fix the left end of the sheet, and then rotating the right support plate relative to the left support plate, the right half of the sheet is tilted. This tilting action allows the right end of the sheet to spread out, thereby facilitating the separation of multi-layer sheets. Then, suction cup two and suction cup three will descend and contact the inclined part of the sheet. After contact, suction cup three will first rise to the same height as suction cup two, so that the sheet between suction cup two and suction cup three will arch upward. If there are other sheets adhered to the bottom of the sucked sheet, during the arching process, since the sheet itself has a certain thickness, relative sliding will occur between the adhered sheet and the sucked sheet, which makes it easy for a gap to appear between the two. Subsequently, the blowing component will blow air into these gaps, making the two sheets easier to separate. Moreover, when the two sheets slide relative to each other, the right end of the adhered sheet will slide further to the right relative to the sucked sheet. After that, suction cup two and suction cup three will rise synchronously. When the right end of the sheet passes through the brush part, the adhered sheet will be more easily peeled off by the brush part. When suction cup one, suction cup two and suction cup three are at the same height, they rise synchronously and then move to the right to place the sheet on the processing line.

[0008] Preferably, the driving assembly includes screw 1, screw 2 and a rotation driving source for driving screw 1 and screw 2 to rotate respectively, screw 1 and screw 2 are both engaged with the workbench, the top of screw 1 is rotatably connected to the left support plate, the top of screw 2 is rotatably connected to a hinge, and the other end of the hinge is slidably connected to the right support plate. Through the rotation driving source, screw 1 and screw 2 can achieve synchronous rotation, thereby driving the left support plate and the right support plate to maintain a horizontal state and rise at the same time in a coordinated manner. When the left support plate reaches a predetermined height, the suction cup 1 will move downward, tightly clamping the left end of the sheet between the suction cup and the left support plate, and then, the screw 2 starts to rotate in the opposite direction, causing the hinge to drop accordingly. During the descending process, the hinge will slide in the slide groove, causing the right end of the right support plate to gradually tilt downward. This action causes the right half of the sheet to tilt and bend, causing the right ends of the sheet to stagger with each other, so that the brush part can easily move the edge of the sheet.

[0009] Preferably, the suction cup assembly also includes a truss and a transverse seat, the transverse seat is slidably installed on the truss left and right, and three groups of telescopic components are installed on the transverse seat, and the bottom ends of the three groups of telescopic components are connected to suction cup one, suction cup two and suction cup three respectively. When the left support plate is lifted to a preset height, suction cup one descends and presses on the left end of the sheet. Subsequently, the right support plate is tilted, thereby causing the right side of the sheet to tilt. Immediately afterwards, suction cup two and suction cup three descend in turn, and achieve contact and adsorption with the inclined part of the sheet. At this stage, suction cup three first rises to the same height as suction cup two, causing the sheet part between suction cup two and suction cup three to arch upward. If there are other sheets adhering to the bottom of the sheet During the arching process, since the sheet itself has a certain thickness, there will be relative sliding between the adhered sheet and the sucked sheet, resulting in a gap between the two. At this time, the blowing component blows air on the gap, effectively prompting the two sheets to separate. In addition, due to the relative sliding between the sheets, the right side of the adhered sheet slides further to the right relative to the sucked sheet. Subsequently, suction cup two and suction cup three rise synchronously. When the right side of the sheet passes through the brush assembly, the adhered sheet is more easily peeled off by the brush assembly. Finally, when suction cup one, suction cup two and suction cup three reach the same height, they will rise synchronously and move to the right to place the sheet on the processing line.

[0010] Preferably, an angle control component is installed between the suction cup two and the suction cup three and the telescopic component, which is used to control the rotation of the suction cup two and the suction cup three when the suction cup two and the suction cup three descend, so that the inclination of the suction cup two and the suction cup three is the same as the inclination of the sheet.

[0011] Preferably, the angle control component is a telescopic drive component, and the top of the suction cup two and the suction cup three are each provided with two hinged parts, one of which is hinged to the telescopic component, and the telescopic drive component is installed between the other hinged part and the telescopic component. When the suction cup two and the suction cup three rise to the same height as the suction cup one, the suction cup two and the suction cup three return to a horizontal state. By controlling the length change of the telescopic drive component, the inclination adjustment of the suction cup two and the suction cup three can be achieved, so that the bottom surface inclination of the suction cup two and the suction cup three is consistent with the inclination of the inclined part on the sheet. When the bottom surface inclination of the two suction cups matches the inclination of the inclined part of the sheet, it can ensure that the suction cup two and the suction cup three are in close contact with the sheet, thereby ensuring the accuracy and reliability of the operation.

[0012] Preferably, the transverse seat is equipped with a sliding drive source for controlling the telescopic assembly connected to suction cup three to slide to the right relative to suction cup two. When suction cup one, suction cup two and suction cup three are at the same height, the telescopic drive component drives suction cup two and suction cup three to rotate and reset. At this time, suction cup two moves to the right relative to suction cup one, so that the sheet between suction cup one and suction cup two is flattened. Then the sliding drive source controls suction cup three to slide in the direction away from suction cup two, so that the sheet between suction cup two and suction cup three is flattened, so that the sheet remains flat when it is placed on the processing line.

[0013] Preferably, an arcuate sleeve is provided at the right end of the bottom surface of the left support plate, and an arcuate slide matched with the arcuate sleeve is provided at the left end of the bottom surface of the right support plate, and the center of the arcuate slide is located in the plane where the top surface of the left support plate is located.

[0014] When the suction cup 2 and the suction cup 3 are lowered relative to the suction cup 1, the arc driving member drives the pressure rod to press on the inclined part of the sheet. When the suction cup 2 and the suction cup 3 are lowered relative to the suction cup 1, the pressure rod is located at the upper right side of the sheet. This position ensures that the pressure rod avoids the suction cup and the sheet to avoid interference during the contact between the suction cup and the sheet. When the suction cup 2 and the suction cup 3 are lowered to the same height as the suction cup 1, the arc driving member is started and drives the pressure rod to move in the direction of the sheet, so that the pressure rod can accurately press on the inclined part of the sheet, thereby effectively avoiding the change in the state of the right end of the sheet being staggered due to gravity sliding. When the suction cup 1 is pressed on the sheet again, the arc driving member again controls the pressure rod to move away from the sheet, thereby completing the giving way, ensuring the smoothness of the entire process and the stability of the sheet.

[0015] Preferably, when the pressure rod is pressed on the sheet material, the angle between the direction of pressure applied by the pressure rod on the sheet material and the right support plate is greater than 85°.

[0016] Preferably, a rubber layer is provided on the portion where the pressure rod contacts the sheet. The design of the rubber layer increases the friction between the pressure rod and the sheet, ensuring that the pressure rod can be firmly pressed on the sheet. At the same time, the softness of the rubber layer can also avoid damage to the sheet, protecting the integrity of the sheet. After the pressure rod presses the sheet, suction cup one, suction cup two and suction cup three rise synchronously, lifting the sheet stably and moving it to the right above the processing line. Subsequently, the suction cup assembly releases the sheet and places it on the processing line, completing the entire loading process.

[0017] By adopting the above technical solution, the beneficial effects of the present invention are:

[0018] 1. After the sheet is placed on the lifting platform, the left end of the sheet is fixed by using a suction cup. The right support plate rotates relative to the left support plate, causing the right half of the sheet to tilt downward. Since the sheets are stacked together, the bending radius of sheets at different heights is different, causing the right ends of the sheets to spread out from each other and be arranged in a stepped manner, thereby facilitating the separation of multiple layers of sheets.

[0019] 2. After the suction cups 2 and 3 descend and come into contact with the inclined part of the sheet, the suction cup 3 will first rise to the same height as the suction cup 2, causing the sheet between the suction cups 2 and 3 to arch upward. If there are other sheets adhered to the bottom of the sucked sheet, during the arching process, due to the certain thickness of the sheet itself, the adhered sheet and the sucked sheet will slide relative to each other, which makes it easy for a gap to appear between the two. Subsequently, the blowing component will blow air into these gaps, making it easier for the two sheets to separate. Moreover, when the two sheets slide relative to each other, the right end of the adhered sheet will slide further to the right relative to the sucked sheet. Afterwards, after the suction cups 2 and 3 rise to the height of the suction cup 1, all the suction cups rise synchronously. When the right end of the sheet passes through the brush part, the adhered sheet will be more easily peeled off by the brush part, which can effectively separate multi-layer films.

[0020] 3. When suction cups 2 and 3 descend, control the rotation of suction cups 2 and 3 so that their inclination is the same as that of the sheet, ensuring that suction cups 2 and 3 fit tightly against the sheet. When suction cups 2 and 3 rise to the same height as suction cup 1, suction cups 2 and 3 return to a horizontal state. When all suction cups rise to their maximum height, the sliding drive source controls suction cup 3 to slide away from suction cup 2, flattening the sheet between suction cups 2 and 3. This keeps the sheet flat when it is placed on the processing line. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0032] like Figure 1 As shown, an operating panel sheet loading device includes a workbench 1, a lifting platform 2, a suction cup assembly 3, a blowing assembly 4 and a brush member 5. The lifting platform 2 is installed above the workbench 1, and the lifting platform 2 can move up and down relative to the workbench 1. A plurality of limit rods are fixedly installed on the top of the workbench 1, and the limit rods are arranged around the outer edge of the lifting platform 2 to prevent the sheets on the lifting platform 2 from falling. The sheets are first neatly stacked on the lifting platform 2, and then the lifting platform 2 rises to a certain height, the suction cup assembly 3 moves downward to contact the topmost sheet, and then the suction cup assembly 3 rises to lift the sheet, and the blowing assembly 4 blows air to the sheet. At the same time, the brush member 5 rotates to move the right end of the sheet, so that the sticky sheets are brushed off to prevent the sheets from sticking together.

[0033] The brush member 5 is rotatably mounted on the workbench 1 and is located above the right end of the lifting platform 2. A driving source for driving its rotation is provided inside the brush member 5. When the suction cup assembly 3 carries the sheet material to the position of the brush member 5, the brush member 5 rotates, and the bristles of the brush member 5 contact the surface of the sheet material. The friction force generated by the rotation separates the adhered sheets, thereby peeling off the multi-layer sheets.

[0034] The blowing assembly 4 has a blowing end, which is located in front of the lifting platform 2. When the suction cup assembly 3 brings the sheet material up to the position of the brush member 5, the blowing end blows air on the sheet material, thereby peeling off the multi-layer sheet material through the airflow.

[0035] In addition, the blowing end of the blowing component 4 can also be set to an adjustable angle to adapt to sheets with different inclinations and improve the blowing effect. The blowing component 4 may include a hair dryer (not shown in the figure) and an air guide duct. The airflow generated by the hair dryer is blown toward the sheet through the air guide duct. The end of the air guide duct is set to a blowing end with an adjustable angle. By adjusting the angle of the blowing end, the blowing direction can be matched with the height of the sheet transportation, thereby better achieving the effect of blowing and peeling.

[0036] In addition, in order to improve the degree of automation and operational convenience of the device, a control system can be set up to uniformly control the operation of each component. The control system can include sensors, controllers and actuators. The sensors are used to detect the status of the lifting platform 2, suction cup assembly 3, blowing assembly 4 and brush assembly 5. The controller sends control instructions according to the signal of the sensor, and the actuator receives the control instructions and performs corresponding actions. Through the control system, the automatic operation of the device can be realized, manual operation can be reduced, and work efficiency can be improved.

[0037] During specific implementation, the structure and parameters of each component can be appropriately adjusted and optimized according to actual needs and process requirements to meet production requirements. For example, the suction force of the suction cup assembly 3, the lifting speed of the lifting platform 2 and the blowing intensity of the blowing assembly 4 can be adjusted according to parameters such as the material, size and thickness of the sheet to obtain the best effect.

[0038] like Figures 1-8As shown, the lifting platform 2 includes a left support plate 21, a right support plate 22 and a driving assembly. The right end of the bottom surface of the left support plate 21 is provided with an arc sleeve 211, and the left end of the bottom surface of the right support plate 22 is provided with an arc slide 221 adapted to the arc sleeve 211, and the center of the arc slide 221 is located in the plane where the top surface of the left support plate 21 is located. The arc slide 221 is slidably installed in the arc sleeve 211, so that the left support plate 21 and the right support plate 22 are hinged. The driving assembly is used to drive the left support plate 21 and the right support plate 22 to rise and fall respectively. When the left support plate 21 and the right support plate 22 are not at the same height, the right support plate 22 tilts, thereby tilting the right half of the sheet, so that the right end of the sheet is no longer flush, so that the right ends of the sheet are staggered with each other.

[0039] The driving assembly includes a screw 1 23, a screw 24 and a rotation driving source (preferably a motor, not shown in the figure). The screw 1 23 and the screw 2 24 are respectively located below the left support plate 21 and the right support plate 22, and the screw 1 23 and the screw 2 24 pass through the workbench 1 and engage with the workbench 1. There are two rotation driving sources, which are respectively connected to the bottom ends of the screw 1 23 and the screw 2 24, so as to control the rotation of the screw 1 23 and the screw 2 24. The top end of the screw 1 23 is rotatably connected to the bottom surface of the left support plate 21, and the top end of the screw 2 24 is rotatably connected to a hinge 241. The other end of the hinge 241 is provided with a slider. The bottom surface of the right support plate 22 is provided with a slide groove along the left and right directions. The slider is slidably fitted in the slide groove, so that The hinge 241 can slide relative to the right support plate 22. When the left support plate 21 and the right support plate 22 need to maintain a horizontal state and rise, the rotating drive source causes the screw 1 23 and the screw 2 24 to rotate synchronously, so that the left support plate 21 and the right support plate 22 maintain their own horizontal state and rise synchronously. When the left support plate 21 rises to a suitable height, the suction cup assembly 3 moves downward so that the left end of the sheet is clamped between the suction cup and the left support plate 21. After that, the screw 24 rotates in the opposite direction, so that the hinge 241 descends. The hinge 241 descends and slides in the slide groove, so that the right end of the right support plate 22 gradually tilts downward, so that the right half of the sheet is bent, and the right ends of the sheet are staggered with each other, which is convenient for the brush part 5 to move the edge of the sheet.

[0040] The suction cup assembly 3 includes suction cup 1 31, suction cup 2 32, suction cup 33, truss 34 and transverse movement seat 35. The number of suction cup 1 31, suction cup 2 32 and suction cup 33 is two. The truss 34 is located above the lifting platform 2. The transverse movement seat 35 is slidably installed on the truss 34 along the left and right directions. The transverse movement seat 35 is equipped with a walking mechanism that can walk along the truss 34. The walking mechanism is preferably a gear rack mechanism controlled by a servo motor. Three groups of telescopic components 36 are installed on the transverse movement seat 35 along the left and right directions. The bottom ends of the three groups of telescopic components 36 are connected to suction cup 1 31, suction cup 2 32 and suction cup 3 33 respectively, so as to control the lifting and lowering of suction cup 1 31, suction cup 2 32 and suction cup 3 33. When the left support plate 21 rises to a suitable height, suction cup 1 31 descends, thereby pressing the left end of the sheet. Then the right support plate 22 tilts, thereby causing the right half of the sheet to tilt, and suction cup 2 32 and suction cup 3 33 descend and align with the sheet The inclined parts of the materials come into contact with each other, and then the suction cup three 33 rises to the same height as the suction cup two 32, so that the sheet between the suction cup two 32 and the suction cup three 33 arches upward. If there is a sheet adhered to the bottom of the sheet being sucked, during the arching process, due to the thickness of the sheet itself, the adhered sheet and the sheet being sucked will slide relative to each other, making it easy for a gap to appear between the two. The blowing component 4 blows air in the gap to separate the two sheets, and the relative sliding of the two sheets will cause the right end of the adhered sheet to slide further to the right relative to the sheet being sucked, and then the suction cup two 32 and the suction cup three 33 rise synchronously. After the suction cup one 31, the suction cup two 32 and the suction cup three 33 are at the same height, the suction cup one 31, the suction cup two 32 and the suction cup three 33 rise synchronously. When the right end of the sheet passes through the brush part 5, the adhered sheet is more easily peeled off by the brush part 5, and then moves to the right to place the sheet on the processing line.

[0041] The telescopic assembly 36 consists of a fixed cylinder and a sliding rod. The fixed cylinder is installed on the transverse seat 35, and the sliding rod is coaxially slidably installed in the fixed cylinder. A driving source for controlling the extension length of the sliding rod is provided in the fixed cylinder, and the bottom end of the sliding rod is connected to the suction cup.

[0042] In order to make suction cup 2 32 and suction cup 3 33 fit the inclined sheet, an angle control assembly is installed between suction cup 2 32 and suction cup 3 33 and telescopic assembly 36, and the angle control assembly includes a telescopic drive member 37. Two hinged parts are provided on the top of suction cup 2 32 and suction cup 3 33, one of which is hinged to the bottom end of the slide rod, and the telescopic drive member 37 is installed between the other hinged part and the slide rod. By controlling the length of the telescopic drive member 37, suction cup 2 32 and suction cup 3 33 can be tilted, so that the slope of the bottom surface of suction cup 2 32 and suction cup 3 33 is the same as the slope of the inclined part of the sheet, so that suction cup 2 32 and suction cup 3 33 can fit the sheet.

[0043] In order to make the sheet material roughly flattened when being transported to the right and avoid excessive wrinkles, a sliding drive source 38 (preferably an electric telescopic rod) is installed on the transverse shift seat 35 for controlling the telescopic assembly 36 connected to the suction cup 3 33 to slide to the right relative to the suction cup 2 32. The fixed cylinder of the telescopic assembly 36 connected to the suction cup 3 33 is slidably installed on the transverse shift seat 35 along the left and right directions. The driving end of the sliding drive source 38 is connected to the fixed cylinder, thereby controlling the suction cup 3 33 to slide to the right relative to the suction cup 2 32. When the suction cups 1 31 and 32 are moved to the right, the suction cup 3 33 is moved to the right relative to the suction cup 2 32. After the suction cup 2 32 and the suction cup 3 33 are at the same height, the telescopic drive member 37 contracts to rotate and reset the suction cup 2 32 and the suction cup 3 33. At this time, the suction cup 2 32 moves to the right relative to the suction cup 1 31. Therefore, the sheet between the suction cup 1 31 and the suction cup 2 32 is flattened. When the suction cup 1 31, the suction cup 2 32 and the suction cup 3 33 rise to the maximum height, the rear sliding drive source 38 controls the suction cup 3 33 to slide to the right relative to the suction cup 2 32, so that the sheet between the suction cup 2 32 and the suction cup 3 33 is flattened, thereby keeping the sheet flat when unloading.

[0044] In order to prevent the stacked sheets from sliding relative to each other after the suction cup 31 rises, causing the right ends of the sheets to no longer be staggered, a fixing component 6 for pressing the sheets on the lifting platform 2 is provided on the right side of the lifting platform 2;

[0045] The fixing assembly 6 includes a pressure rod 61 and an arc driving member 62 (the arc driving member 62 is preferably an electric rotating arm). The arc driving member 62 is installed above the workbench 1, and the pressure rod 61 is fixedly installed on the moving end of the arc driving member 62. When the suction cup 2 32 and the suction cup 3 33 are lowered relative to the suction cup 1 31, the pressure rod 61 is located at the upper right of the sheet, thereby making way for the suction cup and the sheet. When the suction cup 2 32 and the suction cup 3 33 rise to the same height as the suction cup 1 31, the arc driving member 62 drives the pressure rod 61 to move in the direction close to the sheet. The pressure rod 61 is moved, and the movement direction of the pressure rod 61 when it is about to press onto the sheet is basically perpendicular to the inclined part of the sheet, so that the pressure rod 61 is finally pressed on the inclined part of the sheet, and a rubber layer is provided on the part where the pressure rod 61 contacts the sheet. When the pressure rod 61 is pressed on the sheet, the angle between the pressure direction applied by the pressure rod 61 to the sheet and the right support plate 22 is greater than 85°, thereby avoiding the change in the state of the right end being staggered due to the sheet slipping. When the suction cup 31 is pressed on the sheet again, the arc drive member 62 drives the pressure rod 61 to move away from the sheet, thereby making way.

[0046] The working steps are as follows:

[0047] like Figure 2 As shown, in step 1, the sheets are neatly stacked on the lifting platform 2, and the lifting platform 2 is raised to a certain height;

[0048] like Figure 3 and Figure 4As shown, in step 2, the suction cup 1 31 descends to press the left end of the sheet, and then the right support plate 22 tilts to tilt the right half of the sheet, and the suction cups 2 32 and 33 descend to contact the inclined part of the sheet;

[0049] Step 3: The suction cup 3 33 is first raised to the same height as the suction cup 2 32 , so that the sheet between the suction cup 2 32 and the suction cup 3 33 is arched upward, and the blowing assembly 4 blows air into the gap;

[0050] like Figure 5 As shown, in step 4, the second suction cup 32 and the third suction cup 33 rise synchronously. After the first suction cup 31, the second suction cup 32 and the third suction cup 33 are at the same height, the telescopic driving member 37 contracts to rotate the second suction cup 32 and the third suction cup 33 to reset. At this time, the second suction cup 32 moves to the right relative to the first suction cup 31, and the sheet between the first suction cup 31 and the second suction cup 32 is flattened. The pressure rod 61 presses on the inclined part of the sheet to prevent the sheet from slipping and causing the right end to change its staggered state.

[0051] like Figure 6 As shown, in step five, the suction cups 1 31 , 2 32 , and 3 33 continue to rise. When the right end of the sheet passes the brush 5 , the adhered sheet is peeled off by the brush 5 . Finally, the sliding drive source 38 controls the suction cup 3 33 to slide rightward relative to the suction cup 2 32 , so that the sheet between the suction cups 2 32 and 33 is leveled.

[0052] Step 6: Suction cup 1 31 , suction cup 2 32 and suction cup 3 33 rise synchronously and move to the right to place the sheet on the processing line.

[0053] The suction cup 33 first rises to the same height as the suction cup 2 32, so that the sheet between the suction cup 2 32 and the suction cup 3 33 arches upward, and the adhered sheet and the sucked sheet will slide relative to each other, which may cause the two to move. There is a gap. At this time, the blowing component 4 will blow air into the gap, so that the two sheets can be separated. After that, the suction cup 2 32 and the suction cup 3 33 rise synchronously. When the suction cup 1 31, the suction cup 2 32 and the suction cup 3 33 are all at the same height, the pressure rod 61 will press on the inclined part of the sheet, so as to prevent the sheet from slipping and causing the right end to change. Finally, the suction cup 1 31, the suction cup 2 32 and the suction cup 3 33 rise synchronously. When the right end of the sheet passes through the brush part 5, the adhered sheet is more easily brushed. The brush member 5 is peeled off to further ensure the separation effect of the sheet. After rising to the maximum height, the telescopic drive member 37 contracts, so that the inclined state of the suction cup 2 32 and the suction cup 3 33 is restored to the horizontal state, and the sliding drive source 38 controls the suction cup 3 33 to slide to the right relative to the suction cup 2 32, so that the sheet between the suction cup 2 32 and the suction cup 3 33 is flattened, so that the sheet can be kept flat when unloading. Therefore, this method can effectively solve the problem that it is difficult to separate multi-layer films in related technologies.

[0054] In summary, the present invention realizes the effective separation and flattening of multi-layer sheets by adopting the above technical solution, solves the problem of difficulty in separating multi-layer films in related technologies, and improves the efficiency and accuracy of panel sheet loading.
