Description

Technical Field

[0001] The present invention relates to the technical field of feeding devices, and particularly relates to a sheet feeding device for an operation panel. Background Art

[0002] An operation panel sheet is a thin and soft sheet made of plastic, adhesive, rubber or other materials. In the related art, a suction cup is usually used to grasp the film. However, during the process of the suction cup grasping the film, there is a situation where at least two layers of films are grasped at one time. Therefore, it is necessary to separate at least two layers of films grasped by the suction cup to meet the actual production needs.

[0003] The Chinese patent document with the authorization announcement number CN114056934B discloses a double suction cup mechanism for a loading machine. The mechanism includes a support frame, a guide rail assembly, a first suction cup device, a second suction cup device and a conveying device; the first suction cup device and the second suction cup device move along the guide rail assembly under the action of the conveying device; a first-level telescopic mechanism is arranged in the second suction cup device; a two-level telescopic mechanism is arranged in the first suction cup device; the first suction cup device forms a height difference with the second suction cup device under the action of the two-level telescopic mechanism, so that after the first suction cup device passes through the inside of the second suction cup device, it works simultaneously with the first suction cup device in different areas. The two-level telescopic mechanism includes a first telescopic component and a second telescopic component, and the second telescopic component is connected below the first telescopic component.

[0004] When the existing suction cup grasping device separates at least two layers of films, it usually uses the method of air blowing or brushing the edges with a brush. When the two layers of films are attached tightly and the edges close to the brush are in a flush state, since there is no gap between the two layers of films, classification cannot be carried out by air blowing. And since the edges are in a flush state, the brush cannot apply a large peeling force to the lower film. Therefore, the brush cannot ensure effective separation of the two layers of films. Summary of the Invention

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

[0006] An operation panel sheet loading device includes a workbench, a lifting table capable of lifting relative to the workbench, a suction cup assembly arranged above the lifting table, a blowing assembly arranged in front of the lifting table, and a brush member arranged on the right side of the lifting table. A fixing assembly for pressing the sheet on the lifting table is arranged on the right side of the lifting table. The lifting table includes a left support plate, a right support plate, and a driving assembly. One side of the left support plate and the right support plate close to each other is hinged. The driving assembly includes two lifting ends respectively connected to the bottoms of the left support plate and the right support plate. The suction cup assembly includes suction cup one, suction cup two, and suction cup three, and they are distributed from left to right. The sheets are neatly stacked on the lifting table. 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, and the right end of the sheet spreads out. The brush member is located above the right end of the sheet. Suction cup two and suction cup three descend and adhere 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 that, the fixing assembly presses the sheet located on the lifting table. Finally, suction cup one, suction cup two, and suction cup three rise simultaneously and transport the sheet to the processing line.

[0007] The effect is as follows: By using suction cup one to fix the left end of the sheet, then the right support plate rotates relative to the left support plate, making the right half of the sheet in an inclined state. Such an inclined action causes the right end of the sheet to spread out, facilitating the separation of multiple layers of sheets. Then, suction cup two and suction cup three descend and contact the inclined part of the sheet. After contact, suction cup three first rises to the same height as suction cup two, causing the sheet between suction cup two and suction cup three 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, relative sliding will occur between the adhered sheet and the sucked sheet, making it easy to have a gap between them. Subsequently, the blowing assembly blows air into these gaps, making it easier to separate the two sheets. Moreover, when the two sheets slide relative to each other, the right end of the adhered sheet will further slide to the right relative to the sucked sheet. Then, suction cup two and suction cup three rise synchronously. When the right end of the sheet passes by the brush member, the adhered sheet is more easily peeled off by the brush member. When suction cup one, suction cup two, and suction cup three are all 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 rotating 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 rotating 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 descend accordingly. During the descent, 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 movement seat, the transverse movement seat is slidably installed on the truss left and right, and three groups of telescopic components are installed on the transverse movement seat, and the bottom ends of the three groups of telescopic components are respectively connected to suction cup one, suction cup two and suction cup three. 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, so that the right side of the sheet is tilted, and then suction cups two and three descend in turn to 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 cups two and 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 cups one, two and 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 two hinged parts are provided on the top of the suction cup two and the suction cup three, 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, and the inclination adjustment of the suction cup two and the suction cup three can be achieved by controlling the length change of the telescopic drive component, 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 shift 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 for 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 arc sleeve is provided at the right end of the bottom surface of the left support plate, and an arc slide matched with the arc sleeve is provided at the left end of the bottom surface of the right support plate, and the center of the arc slide is located in the plane where the top surface of the left support plate is located.

[0014] Preferably, the fixing assembly includes a pressure rod and an arc driving member for controlling the movement of the pressure rod. During the process of suction cup two and suction cup three descending relative to suction cup one, the pressure rod is located at the upper right corner of the sheet. When suction cup two and suction cup three rise to the same height as suction cup one, the arc driving member drives the pressure rod to press on the inclined part of the sheet. During the process of suction cup two and suction cup three descending relative to suction cup one, the pressure rod is located at the upper right corner of the sheet. This position ensures that during the contact between the suction cup and the sheet, the pressure rod avoids the suction cup and the sheet to avoid interference. When suction cup two and suction cup three descend to the same height as suction cup one, the arc driving member is started to drive 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 of the state of the right end of the sheet being staggered due to gravity sliding. When suction cup one presses on the sheet again, the arc driving member again controls the pressure rod to move in the direction 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 to the sheet material and the right support plate is greater than 85°.

[0016] Preferably, a rubber layer is provided at the portion where the pressing rod contacts the sheet material. The design of the rubber layer increases the friction between the pressing rod and the sheet material, ensuring that the pressing rod can firmly press on the sheet material. At the same time, the softness of the rubber layer can also prevent damage to the sheet material and protect the integrity of the sheet material. After the pressing rod presses the sheet material, the first suction cup, the second suction cup, and the third suction cup rise synchronously, stably lift the sheet material, and move it to the right above the processing line. Subsequently, the suction cup assembly releases the sheet material and places it on the processing line to complete the entire loading process.

[0017] Adopting the above technical solution, the beneficial effects of the present invention are as follows: 1. After the sheet material is placed on the lifting table, the left end of the sheet material is fixed by using the first suction cup, and the right support plate rotates relative to the left support plate, causing the right half of the sheet material to tilt downward. Since the sheet materials are stacked together, the bending radii of the sheet materials at different heights are different, resulting in the right ends of the sheet materials being able to spread apart from each other and arranged in a stepped shape, thus facilitating the separation of multiple layers of sheet materials. 2. The second suction cup and the third suction cup descend and come into contact with the inclined portion of the sheet material. After that, the third suction cup will first rise to the same height as the second suction cup, causing the sheet material between the second suction cup and the third suction cup to arch upward. If there are other sheet materials adhered to the bottom of the sucked sheet material, during the arching process, due to the certain thickness of the sheet material itself, relative sliding will occur between the adhered sheet material and the sucked sheet material, making it easy to form a gap between them. Subsequently, the blowing component will blow air into these gaps, making it easier to separate the two sheet materials. Moreover, when the two sheet materials slide relative to each other, the right end of the adhered sheet material will further slide to the right relative to the sucked sheet material. After that, when the second suction cup and the third suction cup rise to the height of the first suction cup, all the suction cups rise synchronously. When the right end of the sheet material passes by the brush member, the adhered sheet material will be more easily peeled off by the brush member, effectively separating multiple layers of thin films. 3. When the second suction cup and the third suction cup descend, control the second suction cup and the third suction cup to rotate so that the inclination angles of the second suction cup and the third suction cup are the same as the inclination angle of the sheet material, which can ensure that the second suction cup and the third suction cup are in close contact with the sheet material. When the second suction cup and the third suction cup rise to the same height as the first suction cup, the second suction cup and the third suction cup return to the horizontal state. When all the suction cups rise to the maximum height, the sliding drive source controls the third suction cup to slide away from the second suction cup, flattening the sheet material between the second suction cup and the third suction cup, so that when the sheet material is placed on the processing line, the sheet material remains in a flattened state.

[0027] 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.

[0028] like Figure 1 As shown, an operating panel sheet feeding 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. 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 toward 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.

[0029] The brush member 5 is rotatably mounted on the workbench 1 and is located above the right end of the lifting table 2. A driving source for driving its self-rotation is provided inside the brush member 5. When the suction cup assembly 3 drives the sheet to rise to the position of the brush member 5, the brush member 5 rotates, and the bristles of the brush member 5 come into contact with the surface of the sheet. The adhered sheet is separated by the frictional force generated by the rotation, thereby peeling the multi-layer sheet.

[0030] The blowing assembly 4 has a blowing end, and the blowing end is located in front of the lifting table 2. When the suction cup assembly 3 drives the sheet to rise to the position of the brush member 5, the blowing end blows air on the sheet, thereby peeling the multi-layer sheet through the air flow.

[0031] In addition, the blowing end of the blowing assembly 4 can also be set to be adjustable in angle to adapt to sheets with different inclinations and improve the blowing effect. The blowing assembly 4 can include a blower (not shown in the figure) and a wind guiding pipe. The air flow generated by the blower blows towards the sheet through the wind guiding pipe, and the end of the wind guiding pipe is set as an adjustable blowing end. By adjusting the angle of the blowing end, the blowing direction can be made to match the height of the sheet transportation, thereby better achieving the blowing and peeling effect.

[0032] In addition, in order to improve the automation degree and operation convenience of the device, a control system can also be set up to uniformly control the operation of each component. The control system can include sensors, a controller, and actuators. The sensors are used to detect the states of the lifting table 2, the suction cup assembly 3, the blowing assembly 4, and the brush member 5. The controller issues control instructions according to the signals of the sensors, and the actuators receive the control instructions and perform corresponding actions. Through the control system, the automatic operation of the device can be achieved, manual operation can be reduced, and the work efficiency can be improved.

[0033] During specific implementation, the structures and parameters of each component can be appropriately adjusted and optimized according to actual requirements and process requirements to meet the production requirements. For example, according to parameters such as the material, size, and thickness of the sheet, parameters such as the suction force of the suction cup assembly 3, the lifting speed of the lifting table 2, and the blowing intensity of the blowing assembly 4 can be adjusted to obtain the best effect.

[0034] Such as Figures 1-8As shown, the lifting platform 2 includes a left support plate 21, a right support plate 22 and a driving assembly. An arc sleeve 211 is provided at the right end of the bottom surface of the left support plate 21, and an arc slide 221 matched with the arc sleeve 211 is provided at the left end of the bottom surface of the right support plate 22, 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 is tilted, so that the right half of the sheet is tilted, 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.

[0035] 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 24 are respectively located below the left support plate 21 and the right support plate 22, and the screw 1 23 and the screw 24 pass through the workbench 1 and mesh 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 rotationally connected to the bottom surface of the left support plate 21, the top end of the screw 24 is rotationally 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 installed in the slide groove, so as to 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 can 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. Thereafter, 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, which is convenient for the brush member 5 to move the edge of the sheet.

[0036] The suction cup assembly 3 includes a first suction cup 31, a second suction cup 32, a third suction cup 33, a truss 34 and a transverse moving seat 35. The number of the first suction cup 31, the second suction cup 32 and the third suction cup 33 is two each. The truss 34 is located above the lifting table 2. The transverse moving seat 35 is slidably mounted on the truss 34 in the left-right direction. A traveling mechanism capable of traveling along the truss 34 is mounted on the transverse moving seat 35. The traveling mechanism is preferably a rack and pinion mechanism controlled by a servo motor. Three sets of telescopic assemblies 36 are mounted on the transverse moving seat 35 in the left-right direction. The bottom ends of the three sets of telescopic assemblies 36 are respectively connected to the first suction cup 31, the second suction cup 32 and the third suction cup 33, so as to control the lifting of the first suction cup 31, the second suction cup 32 and the third suction cup 33. When the left support plate 21 rises to an appropriate height, the first suction cup 31 descends, so as to press the left end of the sheet material. Then the right support plate 22 inclines, so that the right half of the sheet material inclines. The second suction cup 32 and the third suction cup 33 descend to contact the inclined part of the sheet material. Then the third suction cup 33 first rises to the same height as the second suction cup 32, so that the sheet material between the second suction cup 32 and the third suction cup 33 arches upward. If there is an adhered sheet material at the bottom of the sucked sheet material, during the arching process, due to the thickness of the sheet material itself, there will be relative sliding between the adhered sheet material and the sucked sheet material, making it easy for the two to have a gap. The blowing assembly 4 blows air into the gap so that the two sheet materials can be separated. And the relative sliding of the two sheet materials will cause the right end of the adhered sheet material to slide further to the right relative to the sucked sheet material. Then 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 first suction cup 31, the second suction cup 32 and the third suction cup 33 rise synchronously. When the right end of the sheet material passes through the brush member 5, the adhered sheet material is more easily peeled off by the brush member 5, and then moves to the right to place the sheet material on the processing line.

[0037] The telescopic assembly 36 is composed of a fixed cylinder and a sliding rod. The fixed cylinder is mounted on the transverse moving seat 35. The sliding rod is coaxially and slidably mounted in the fixed cylinder. A driving source for controlling the extending length of the sliding rod is arranged in the fixed cylinder. The bottom end of the sliding rod is connected to the suction cup.

[0038] In order to make the second suction cup 32 and the third suction cup 33 fit the inclined sheet material, an angle control assembly is installed between the second suction cup 32 and the third suction cup 33 and the telescopic assembly 36. The angle control assembly includes a telescopic driving member 37. Two hinge parts are arranged at the top of each of the second suction cup 32 and the third suction cup 33. One of the hinge parts is hinged to the bottom end of the sliding rod. The telescopic driving member 37 is installed between the other hinge part and the sliding rod. By controlling the length of the telescopic driving member 37, the second suction cup 32 and the third suction cup 33 are inclined, so that the slope of the bottom surface of the second suction cup 32 and the third suction cup 33 is the same as the slope of the inclined part of the sheet material, so that the second suction cup 32 and the third suction cup 33 can fit the sheet material.

[0039] In order to enable the sheet to be flattened approximately when being transported to the right and avoid excessive wrinkles, a sliding drive source 38 (preferably an electric telescopic rod) for controlling the telescopic assembly 36 connected to the third suction cup 33 to slide rightward relative to the second suction cup 32 is installed on the transverse movement seat 35. The fixed cylinder of the telescopic assembly 36 connected to the third suction cup 33 is slidably installed on the transverse movement seat 35 in the left-right direction, and the drive end of the sliding drive source 38 is connected to this fixed cylinder, so as to control the third suction cup 33 to slide rightward relative to the second suction cup 32. After the first suction cup 31, the second suction cup 32 and the third suction cup 33 are at the same height, the telescopic drive member 37 contracts to rotate and reset the second suction cup 32 and the third suction cup 33. At this time, the second suction cup 32 moves rightward relative to the first suction cup 31. Therefore, the sheet between the first suction cup 31 and the second suction cup 32 is flattened. After the first suction cup 31, the second suction cup 32 and the third suction cup 33 rise to the maximum height, the rear sliding drive source 38 controls the third suction cup 33 to slide rightward relative to the second suction cup 32, so as to flatten the sheet between the second suction cup 32 and the third suction cup 33, thereby keeping the sheet in a flattened state during sheet feeding.

[0040] In order to prevent the stacked sheets from sliding relative to each other after the first suction cup 31 rises, resulting in the right ends of the sheets no longer being staggered, a fixing assembly 6 for pressing the sheets on the lifting table 2 is provided to the right of the lifting table 2; The fixing assembly 6 includes a pressing rod 61 and an arc drive member 62 (the arc drive member 62 is preferably an electric rotating arm). The arc drive member 62 is installed above the workbench 1, and the pressing rod 61 is fixedly installed on the moving end of the arc drive member 62. During the process of the second suction cup 32 and the third suction cup 33 descending relative to the first suction cup 31, the pressing rod 61 is located above the right of the sheet, so as to make way for the suction cup and the sheet. When the second suction cup 32 and the third suction cup 33 rise to the same height as the first suction cup 31, the arc drive member 62 drives the pressing rod 61 to move towards the sheet, and the movement direction of the pressing rod 61 when it is about to press on the sheet is substantially perpendicular to the inclined part of the sheet. Finally, the pressing rod 61 presses on the inclined part of the sheet, and a rubber layer is provided at the part where the pressing rod 61 contacts the sheet. When the pressing rod 61 presses on the sheet, the included angle between the pressure direction applied by the pressing rod 61 to the sheet and the right support plate 22 is greater than 85°, so as to prevent the state change of the right ends being staggered caused by the sheet slipping. When the first suction cup 31 presses on the sheet again, the arc drive member 62 drives the pressing rod 61 to move away from the sheet, so as to make way.

[0041] The working steps are as follows: As Figure 2 shown, Step 1: Stack the sheets neatly on the lifting table 2, and the lifting table 2 rises to a certain height; As 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; Step 3, the suction cup 3 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 blowing assembly 4 blows air in the gap; like Figure 5 As shown, in step 4, the suction cup 2 32 and the suction cup 3 33 rise synchronously, and after the suction cup 1 31, the suction cup 2 32 and the suction cup 3 33 are at the same height, the telescopic driving 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, and the sheet between the suction cup 1 31 and the suction cup 2 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 state; like Figure 6 As shown, in step five, the suction cup 1 31, the suction cup 2 32 and the suction cup 3 33 continue to rise, and when the right end of the sheet passes through the brush member 5, the adhered sheet is peeled off by the brush member 5, and 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 cup 2 32 and the suction cup 3 33 is flattened; 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.

[0042] Working principle: When working, first of all, the sheets on the operation panel need to be neatly stacked on the lifting platform 2, and then, by rotating the driving source, the lead screw 1 23 and the lead screw 2 24 rotate synchronously, so as to ensure that the left support plate 21 and the right support plate 22 can synchronously maintain their own horizontal state and rise. When the left support plate 21 rises to a suitable height, the suction cup 1 31 will descend, thereby pressing the left end of the sheet. Subsequently, the lead screw 24 starts to rotate in the opposite direction, causing the right support plate 22 to descend and tilt, so that the right half of the sheet is bent, so that the right ends of the sheets are staggered with each other, which makes it convenient for the brush part 5 to move the edge of the sheet. Then, the suction cup 2 32 and the suction cup 3 33 descend, contact the inclined part of the sheet, and lift the sheet by suction. The suction cup 3 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 relative sliding will occur between the adhered sheet and the sucked sheet, which may cause the two to When the first suction cup 31, the second suction cup 32 and the third suction cup 33 are at the same height, the pressure rod 61 will press on the inclined part of the sheet to prevent the sheet from slipping and causing the right end to change. Finally, the first suction cup 31, the second suction cup 32 and the third suction cup 33 rise synchronously. When the right end of the sheet passes through the brush member 5, the adhered sheet is more easily brushed. The brush member 5 is peeled off to further ensure the separation effect of the sheets. 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 discharging. Therefore, this method can effectively solve the problem that it is difficult to separate multi-layer films in related technologies.

[0043] In summary, the present invention realizes effective separation and flattening of multi-layer sheets by adopting the above technical scheme, solves the problem of difficulty in separating multi-layer films in related technologies, and improves the efficiency and accuracy of panel sheet feeding.

A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
