Description

Technical Field

[0001] This invention relates to the field of film application equipment technology, and more particularly to a concave film application machine. Background Technology

[0002] In existing technologies, when applying films to the surface of a product, a peel-off film is applied to its upper surface. After the film is applied and pressed in place, the peel-off film on its upper surface needs to be peeled off. Since the peel-off film is almost in contact with the upper surface of the product, it is difficult to peel off the film, especially for products with concave structures, where the peel-off film is even more difficult to peel off after the film is applied to the concave surface.

[0003] As is the current situation, whether using a robotic arm or manual peeling, it is easy to touch the product and damage it. It is also easy to touch the film being applied, making the film easily damaged and displaced, resulting in inaccurate application and a high defect rate in product film application.

[0004] In response, the inventor of this patent, drawing on work experience, deeply considered the problems encountered in his work, reviewed a large amount of scientific research data and literature, and gradually conceived and designed this application through a novelty search to solve the relevant technical problems. Summary of the Invention

[0005] This invention aims to at least partially solve one of the technical problems in related technologies. Therefore, the object of this invention is to provide a concave laminating machine.

[0006] To achieve one of the above objectives, a concave laminating machine according to an embodiment of the present invention is used to apply a film to the surface of a product. The film includes an upper peelable film and a film sheet adhered to the front of the underside of the upper peelable film, comprising:

[0007] Machine tool;

[0008] Fixture table; the fixture table is located on the upper right front part of the machine table and is used to fix the product.

[0009] Film-taking platform; the film-taking platform is located at the right middle part of the upper surface of the machine platform;

[0010] A film-taking device; the film-taking device is located beside the film-taking platform and includes a three-dimensional moving mechanism A that can move left and right, forward and backward, and up and down, and a film-taking suction head located on the three-dimensional moving mechanism A; the film-taking suction head is formed in a stepped shape so that it has a first vacuum nozzle located at the front and a second vacuum nozzle located at the rear with a height higher than the first vacuum nozzle.

[0011] A top film device; the top film device is located beside the film taking platform and includes a support member, a lifting member located at the rear of the support member, and a top block located on the upper part of the lifting member with an initial height equal to or lower than the height of the support member;

[0012] When the three-dimensional moving mechanism A controls the film-taking suction head to move to the first position, the first vacuum nozzle adheres to the upper surface of the pre-set upper tear film front part on the film-taking platform to pick up the film sheet at the front part of the upper tear film and its bottom.

[0013] When the three-dimensional moving mechanism A controls the film-taking suction head to move to the second position, the lower surface of the film sucked by the first vacuum nozzle is lifted by the supporting member, and the second vacuum nozzle is located directly above the top block; the lifting member is used to control the top block to push the upper tear film back part, so that the upper tear film back part is tilted upward and shaped and fits against the bottom surface of the second vacuum nozzle and is sucked by the second vacuum nozzle;

[0014] When the three-dimensional moving mechanism A controls the film-taking suction head to move to the third position, the film sheet at the front of the upper tear film and the bottom of the film sheet sucked by the first vacuum nozzle are driven and attached to the product surface.

[0015] In addition, the concave laminating machine according to the above embodiments of the present invention may also have the following additional technical features:

[0016] According to one embodiment of the present invention, it further includes a film pressing device;

[0017] The pressing device is mounted on the upper part of the fixture platform and includes a fixed frame, a front-to-back moving mechanism A mounted on the fixed frame, a lifting mechanism mounted on the front-to-back moving mechanism A, and a pressing head component mounted at the bottom of the lifting mechanism.

[0018] When the forward and backward moving mechanism A controls the pressure head component to move forward and backward to above the product and face the upper film front and the bottom film in the vertical direction, the lifting mechanism can drive the pressure head component to descend a preset stroke to press the film onto the product surface.

[0019] According to one embodiment of the present invention, the pressure head component includes an upper connecting plate, a lower connecting plate, a pressure-relieving member, and a pressure block for pressing the diaphragm;

[0020] The upper connecting plate is fixed to the bottom of the lifting mechanism, and the pressure-relieving component is fixed vertically between the lower bottom surface of the upper connecting plate and the upper top surface of the lower connecting plate; the pressure block is fixed to the bottom of the lower connecting plate.

[0021] According to one embodiment of the present invention, the pressure head component further includes a left support plate, a right support plate, a left slide rail, a right slide rail, a left slider, and a right slider;

[0022] The left support plate and the right support plate are vertically fixed to the left and right sides of the bottom surface of the upper connecting plate; the lower part of the left support plate has a left support groove for supporting the left end of the lower connecting plate; the lower part of the right support plate has a right support groove for supporting the right end of the lower connecting plate.

[0023] The left slide rail is vertically fixed to the right end face of the left support plate, and a pressure-relieving spring A is fixed between its bottom and the left end of the lower connecting plate; the right slide rail is vertically fixed to the left end face of the right support plate, and a pressure-relieving spring B is fixed between its bottom and the right end of the lower connecting plate; the pressure-relieving spring A and the pressure-relieving spring B constitute the pressure-relieving component;

[0024] The left and right sliders are respectively slidably mounted in the left and right slide rails, and their bottoms are connected to the upper surface of the lower connecting plate.

[0025] According to one embodiment of the present invention, the pressure head component further includes a pressure relief spring C and a pressure sensor for detecting the pressure under the diaphragm;

[0026] The lower connecting plate has a downward-facing locking groove A at the center of its upper upper surface, and the upper connecting plate has an upward-facing locking groove B directly opposite the locking groove A at the center of its lower bottom surface. The pressure sensor is locked in the locking groove A, and the pressure relief spring C is naturally positioned between the top of the pressure sensor and the lower bottom surface of the upper connecting plate. The upper end of the pressure relief spring C is connected to a connecting block that is inserted into the locking groove B.

[0027] According to one embodiment of the present invention, it further includes a CCD imaging component for photographing and positioning the diaphragm sucked up by the first vacuum nozzle;

[0028] The CCD imaging component is positioned upwards on the upper surface of the machine platform and located beside the film-taking platform; the film-taking device also includes a circumferential rotating component located on the three-dimensional moving mechanism A, which can move left and right, forward and backward, and up and down under the control of the three-dimensional moving mechanism, and the film-taking suction head is located at the bottom of the circumferential rotating component.

[0029] According to one embodiment of the present invention, it further includes:

[0030] A left-right moving mechanism; the left-right moving mechanism is located at the front of the upper end of the machine platform along the left-right direction, and the fixture platform is provided on it;

[0031] A film-tearing device; the film-tearing device is located on the left front part of the upper surface of the machine platform, including a three-dimensional moving mechanism B that can move left and right, forward and backward, and up and down, and an openable and closable gripper located on the three-dimensional moving mechanism B;

[0032] The openable gripper is used to grip the rear part of the upper tear film when the left and right moving mechanism controls the fixture table to move to the left by a preset stroke so that the fixture table is directly below it, so as to tear the upper tear film from the upper part of the film.

[0033] According to one embodiment of the invention, it further includes a waste collection box with an open upper portion for collecting the upper film tear;

[0034] The waste collection box is located at the left center of the upper surface of the machine platform; under the control of the three-dimensional moving mechanism B, the openable gripper can be moved to directly above the waste collection box so as to drop the upper film it grips into the waste collection box.

[0035] According to one embodiment of the present invention, it further includes a film conveying device for forward conveying the film to the upper surface of the film taking platform;

[0036] The film-coating conveying device is located on the right rear part of the upper surface of the machine platform, including a material rack, a release disc component installed on the upper part of the material rack for releasing forward a strip of incoming material on which multiple films are uniformly adhered along the length direction on the upper surface, a guide rod component installed in the middle of the material rack, and a winding disc component A installed at the lower part of the material rack for winding up the strip of waste material.

[0037] The bottom of the film-taking platform is hollowed out. The strip of material released forward is guided by the guide rod component, passes from back to front over the upper surface of the film-taking platform, and then rotates from the front side of the film-taking platform downward and then backward from the bottom of the film-taking platform to the winding reel component A.

[0038] According to one embodiment of the present invention, it further includes a forward and backward movement mechanism B for assisting in peeling off the film;

[0039] The forward and backward moving mechanism B is located in the middle right of the upper surface of the machine platform along the forward and backward direction; the film taking platform is mounted on the forward and backward moving mechanism B;

[0040] When the forward and backward moving mechanism B drives the film taking platform to move backward, and the release disc component and the take-up disc component A tighten the strip material that is released forward and rotated backward, and when the first vacuum nozzle sucks up the film conveyed to the upper surface of the film taking platform, the film peels off from the strip material.

[0041] The beneficial effects of this invention are:

[0042] Firstly, in specific implementation, the concave film applicator provided in this application uses the three-dimensional moving mechanism A to control the film-taking suction head to move to the third position, so that the film sheet at the front and bottom of the upper peelable film picked up by the first vacuum nozzle is driven and applied to the preset position on the product surface. The three-dimensional moving mechanism A can control the film-taking suction head to move left and right, forward and backward, and up and down, so that the film sheet at the front and bottom of the upper peelable film picked up by the first vacuum nozzle can move flexibly. Within a certain range of movement, it can be moved to the required position to apply the film sheet to the appropriate position on the upper surface of the product. This makes the application flexible and applicable, and can greatly improve the efficiency and speed of product film application.

[0043] Secondly, when peeling off the upper film, this application pre-bends and shapes its rear part upwards and backwards, causing it to curl up. Subsequently, even when pulling off the curled rear part, this process, whether using a robotic arm or manual pulling, minimizes contact with the product, preventing damage and also minimizing contact with the applied film. This ensures the film is less likely to be damaged or displaced, resulting in precise placement and a low defect rate. This application is particularly suitable for products with concave surfaces on their upper surfaces. During operation, the rear part of the upper film is bent and curled upwards and backwards, protruding above the relevant concave surface. Pulling it off at this point also minimizes contact with the product and the film.

[0044] Thirdly, by setting the film pressing device, after the film is applied to a preset position on the upper surface of the product, the upper layer of the peeling film is still retained on its upper surface. At this time, the first vacuum nozzle and the second vacuum nozzle can release the vacuum to loosen the upper layer of the peeling film, and the film taking head can be removed by the three-dimensional moving mechanism A. Then, the pressing head component can be controlled by the forward and backward moving mechanism A to move forward and backward to above the product and face the front and bottom of the upper layer of the peeling film in the vertical direction. Then, the lifting mechanism can be used to drive the pressing head component to descend a preset stroke to press the film onto the upper surface of the product. In this way, it is not easy for the film to be torn off together, making the film application more stable and reliable, and its fixation more secure.

[0045] Fourthly, when the lifting mechanism drives the pressure block of the pressure head component to descend a preset stroke to press the diaphragm onto the upper surface of the product, the pressure buffer component prevents the pressure block from forcibly pressing the diaphragm onto the upper surface of the product. The pressure buffer component buffers the downward pressure, which can effectively protect the diaphragm and the product from being crushed, thus making the application more reliable in use.

[0046] Fifthly, by setting the pressure sensor, the downward pressure of the diaphragm can be detected in real time, making the downward pressure data controllable, so that the diaphragm and the product are not easily damaged. By setting the pressure relief spring C, the pressure sensor is well protected and is not easily damaged by hard pushing in the vertical direction.

[0047] Sixthly, regarding the tearing of the upper film, this application provides a film-tearing device. After the film is pressed and fixed to the upper surface of the product, the front-to-back moving mechanism A and the lifting mechanism drive the pressure head component to move away from the fixture table. Then, the left-to-right moving mechanism controls the fixture table to move to the left by a preset stroke until the fixture table is directly below the film-tearing device. At this time, the three-dimensional moving mechanism B of the film-tearing device controls its openable and closable jaws to move towards the rear of the upper film, so as to use the openable and closable jaws to grip the rear of the upper film. During the upward movement controlled by the three-dimensional moving mechanism B, the upper film is torn off from the upper part of the film. In this way, the tearing of the upper film is carried out by mechanical automation, resulting in high film-tearing efficiency.

[0086] The concave film applicator 1000 of the present invention will now be described in detail with reference to the accompanying drawings.

[0087] Reference Figures 1 to 9 As shown, the concave film applicator 1000 provided according to an embodiment of the present invention is used to apply film to the surface of product 2000. The film application includes an upper peel film and a film sheet adhered to the front of the bottom surface of the upper peel film. The lower surface of the film sheet has an adhesive surface. Based on this, the present application includes a machine base 10, a fixture table 20, a film taking platform 30, and a film taking device 40.

[0088] The fixture platform 20 is located on the front right side of the upper end face of the machine base 10 for fixing the product 2000; the film-taking platform 30 is located on the middle right side of the upper end face of the machine base 10, and the film is pre-placed on it during use; the film-taking device 40 is located beside the film-taking platform 30 and includes a three-dimensional moving mechanism A401 that can move left and right, forward and backward, and up and down, and a film-taking suction head 402 located on the three-dimensional moving mechanism A401; the film-taking suction head 402 is formed in a stepped shape so that it has a first vacuum nozzle 4021 located at the front and a second vacuum nozzle 4022 located at the rear with a height higher than the first vacuum nozzle 4021. Specifically, refer to Figure 2 and Figure 3As shown; the top film device 50 is located beside the film-taking platform 30, and includes a support member 501, a lifting member 502 located at the rear of the support member 501, and a top block 503 located on the upper part of the lifting member 502 with an initial height equal to or lower than the height of the support member 501. Specifically, refer to Figure 4 As shown.

[0089] When the three-dimensional moving mechanism A401 controls the film-taking suction head 402 to move to the first position, the first vacuum suction nozzle 4021 adheres to the upper surface of the pre-set upper layer tear film front part on the film-taking platform 30 to pick up the film sheet of the upper layer tear film front part and its bottom.

[0090] When the three-dimensional moving mechanism A401 controls the film-taking suction head 402 to move to the second position, the lower surface of the film sucked by the first vacuum nozzle 4021 is lifted by the support member 501, and the second vacuum nozzle 4022 is located directly above the top block 503; the lifting member 502 is used to control the top block 503 to push the upper layer of the torn film back part, so that the upper layer of the torn film back part is tilted upward and shaped and adheres to the lower surface of the second vacuum nozzle 4022 and is sucked by the second vacuum nozzle 4022;

[0091] When the three-dimensional moving mechanism A401 controls the film-taking suction head 402 to move to the third position, the film sheet at the front and bottom of the upper film-tearing part picked up by the first vacuum nozzle 4021 is driven and attached to the upper surface of the product 2000.

[0092] Based on the above, it is clear that this application is mainly used as a concave laminating machine 1000 in specific implementation.

[0093] Specifically, when applying this application, the film is pre-installed on the film-receiving platform 30. Based on this, the general working principle of this application is as follows:

[0094] First, the three-dimensional moving mechanism A401 controls the film-taking suction head 402 to move to the first position, so that the first vacuum nozzle 4021 adheres to the upper surface of the upper peeling front part of the film pre-placed on the film-taking platform 30, so as to pick up the upper peeling front part and the film sheet adhered to its bottom.

[0095] Then, the three-dimensional moving mechanism A401 controls the membrane suction head 402 to move to the second position, so that the lower surface of the membrane sucked by the first vacuum nozzle 4021 is lifted by the support member 501. At this time, the second vacuum nozzle 4022 will be located directly above the top block 503.

[0096] Subsequently, the lifting member 502 controls the top block 503 to push the rear part of the upper tear film upward, so that the rear part of the upper tear film is tilted upward and shaped to fit the bottom surface of the second vacuum nozzle 4022 and be sucked up by the second vacuum nozzle 4022. In this way, the rear part of the upper tear film is bent and shaped backward and upward.

[0097] Then, the film-taking suction head 402 is controlled to move to the third position by the three-dimensional moving mechanism A401, so that the film sheet at the front and bottom of the upper film peeling part picked up by the first vacuum nozzle 4021 is driven and attached to the preset position on the upper surface of the product 2000.

[0098] Finally, after the film is attached to the preset position on the upper surface of the product 2000, the upper film, which has been bent and shaped backward and upward, can be pulled apart by a robotic arm or manually to separate it from the attached film.

[0099] Clearly, the use of this application will have the following technical effects:

[0100] On the one hand, this application uses the three-dimensional moving mechanism A401 to control the film-taking suction head 402 to move to the third position, so that the film sheet at the front and bottom of the upper peelable film picked up by the first vacuum nozzle 4021 is driven and applied to the preset position on the surface of the product 2000. The three-dimensional moving mechanism A401 can control the film-taking suction head 402 to move left and right, back and forth and up and down, so that the film sheet at the front and bottom of the upper peelable film picked up by the first vacuum nozzle 4021 can move flexibly. Within a certain range of movement, it can be moved to the required position to apply the film sheet to the appropriate position on the upper surface of the product 2000. This makes the application flexible and applicable, and can greatly improve the film application efficiency and speed of the product 2000.

[0101] On the other hand, when peeling off the upper film, this application pre-bends and shapes its rear part upwards and backwards and allows it to be adsorbed, so that it is raised. Subsequently, even if the rear part that is bent and raised upwards and backwards is pulled to peel it off, this process, whether using a robotic arm or directly using manual hand to pull and peel off its rear part, is unlikely to touch the product 2000, is unlikely to damage the product 2000, and is also unlikely to touch the film to be applied, so that the film to be applied is not likely to be damaged or displaced, so that the application position is very accurate, resulting in a low defect rate of film application on the product 2000.

[0102] Furthermore, this application is particularly suitable for applying a film to the concave surface of a product 2000 with a concave upper surface. During operation, the upper film can be bent and shaped to be exposed on the upper part of the relevant concave surface after being peeled off. At this time, it is not easy to touch the product 2000 and the film when it is pulled off.

[0103] Furthermore, through the above-mentioned optimized design, the whole constituted by this application is highly practical and has a good effect in use.

[0104] Furthermore, in specific implementation, in particular, in comparison... Figure 5 , Figure 6 and Figure 7 As shown, according to one embodiment of the present invention, this application also includes a film pressing device 60;

[0105] The pressing device 60 is mounted on the upper part of the fixture table 20 and includes a fixed frame 601, a front and rear moving mechanism A602 provided on the fixed frame 601, a lifting mechanism 603 provided on the front and rear moving mechanism A602, and a pressing head component 604 provided at the bottom of the lifting mechanism 603.

[0106] When the forward and backward moving mechanism A602 controls the pressing head component 604 to move forward and backward above the product 2000 and face the upper film front and the bottom film in the vertical direction, the lifting mechanism 603 can drive the pressing head component 604 to descend a preset stroke to press the film onto the surface of the product 2000.

[0107] Therefore, by setting the film pressing device 60, after the film is attached to a preset position on the upper surface of the product 2000, the upper layer of the film is still retained on its upper surface. At this time, the first vacuum nozzle 4021 and the second vacuum nozzle 4022 can release the vacuum to loosen the upper layer of the film, and the film taking head 402 can be removed by the three-dimensional moving mechanism A401. Then, the pressing head component 604 can be moved back and forth to above the product 2000 and directly facing the front and bottom of the upper layer of the film in the vertical direction by the forward and backward moving mechanism A602. Then, the lifting mechanism 603 can be used to drive the pressing head component 604 to descend a preset stroke to press the film onto the upper surface of the product 2000.

[0108] Subsequently, when the film is pressed and fixed and does not easily detach from the surface of product 2000, a robotic arm or manual pull can be used to separate the upper film, which has been bent and shaped backward and upward, from the attached film.

[0109] In this way, the membrane is less likely to be torn off along with the film, making the film more stable and reliable to install, and its fixation is more secure.

[0110] Preferably, in this technical solution, compared with Figure 6 and Figure 7 As shown, according to an embodiment of the present invention, the pressure head component 604 includes an upper connecting plate 6041, a lower connecting plate 6042, a pressure relief member, and a pressure block 6043 for pressing and fixing the diaphragm.

[0111] The upper connecting plate 6041 is fixedly disposed at the bottom of the lifting mechanism 603, the pressure relief member is fixedly disposed vertically between the lower bottom surface of the upper connecting plate 6041 and the upper end surface of the lower connecting plate 6042, and the pressure block 6043 is fixedly disposed at the bottom of the lower connecting plate 6042.

[0112] Therefore, when the lifting mechanism 603 drives the pressure block 6043 of the pressure head component 604 to descend a preset stroke to press the diaphragm onto the upper surface of the product 2000, the pressure buffer component prevents the pressure block 6043 from forcibly pressing the diaphragm onto the upper surface of the product 2000. The pressure buffer component buffers the downward pressure, effectively protecting the diaphragm and the product 2000 from damage, thus improving the reliability of this application.

[0113] Furthermore, preferably, in this technical solution, the comparison continues. Figure 6 and Figure 7 As shown, according to one embodiment of the present invention, the pressure head component 604 further includes a left support plate 6044, a right support plate 6045, a left slide rail 6046, a right slide rail 6047, a left slider 6048, and a right slider 6049;

[0114] The left support plate 6044 and the right support plate 6045 are vertically fixed on the left and right sides of the lower bottom surface of the upper connecting plate 6041; the lower part of the left support plate 6044 has a left support groove 60441 for supporting the left end of the lower connecting plate 6042; the lower part of the right support plate 6045 has a right support groove 60451 for supporting the right end of the lower connecting plate 6042.

[0115] Furthermore, the left slide rail 6046 is vertically fixed to the right end face of the left support plate 6044, and a pressure-relieving spring A6050 is fixed between its bottom and the left end of the lower connecting plate 6042; the right slide rail 6047 is vertically fixed to the left end face of the right support plate 6045, and a pressure-relieving spring B6051 is fixed between its bottom and the right end of the lower connecting plate 6042; the pressure-relieving spring A6050 and the pressure-relieving spring B6051 constitute the pressure-relieving component, and both remain in a natural state initially.

[0116] Based on this, in this application, the left slider 6048 and the right slider 6049 are respectively slidably mounted in the left slide rail 6046 and the right slide rail 6047, and their bottoms are connected to the upper surface of the lower connecting plate 6042.

[0117] In this regard, it is clear that

[0118] On the one hand, since the lower part of the left support plate 6044 has a left support groove 60441 for supporting the left end of the lower connecting plate 6042, and the lower part of the right support plate 6045 has a right support groove 60451 for supporting the right end of the lower connecting plate 6042, the lower connecting plate 6042 is initially supported by the left support groove 60441 and the right support groove 60451, so that the pressure relief spring A6050 and the pressure relief spring B6051 can remain in their natural state and not be pulled down by the lower connecting plate 6042, so that they can maintain their elasticity well and have a long service life.

[0119] On the other hand, when the left slider 6048 and the right slider 6049 are respectively slidably mounted in the left slide rail 6046 and the right slide rail 6047, and their bottoms are connected to the upper surface of the lower connecting plate 6042, the lower connecting plate 6042 can only move in the vertical direction when it drives the pressure block 6043 to move up and down, so that it can play a good vertical guiding role, and the pressure block 6043 is not easy to shift circumferentially during the vertical movement.

[0120] Furthermore, through the above-mentioned optimized design, the overall performance of this application can be effectively improved.

[0121] Furthermore, in specific implementation, it is still necessary to refer to... Figure 6 and Figure 7 As shown, according to one embodiment of the present invention, the pressure head component 604 further includes a pressure relief spring C6052 and a pressure sensor 6053 for detecting the pressure under the diaphragm;

[0122] The lower connecting plate 6042 has a downward-facing locking groove A60421 on the upper surface, and the upper connecting plate 6041 has an upward-facing locking groove B60411 on the lower surface, directly opposite the locking groove A60421. The pressure sensor 6053 is locked in the locking groove A60421. The pressure relief spring C6052 is naturally positioned between the top of the pressure sensor 6053 and the lower surface of the upper connecting plate 6041, and the upper end of the pressure relief spring C6052 is connected to a connecting block 60521 that is inserted into the locking groove B60411.

[0123] Therefore, it can be clearly seen that by setting the pressure sensor 6053, the downward pressure of the diaphragm can be detected in real time, making the downward pressure data controllable, so that the diaphragm and product 2000 are not easily damaged. By setting the pressure relief spring C6052, the pressure sensor 6053 is well protected and is not easily damaged by hard pushing in the vertical direction.

[0124] Furthermore, in specific implementation, in accordance with Figure 1 As shown, according to an embodiment of the present invention, this application further includes a CCD imaging component 70 for photographing and positioning the diaphragm picked up by the first vacuum nozzle 4021;

[0125] The CCD imaging component 70 is positioned upwards on the upper surface of the machine base 10 and located beside the film-taking platform 30; based on this, the comparison... Figure 2 and Figure 3 As shown, the film-taking device 40 of this application further includes a circumferential rotating component 403 disposed on the three-dimensional moving mechanism A401, which can move left and right, forward and backward and up and down under the control of the three-dimensional moving mechanism, and the film-taking suction head 402 is disposed at the bottom of the circumferential rotating component 403.

[0126] In this regard, it should be noted that after the first vacuum nozzle 4021 picks up the film at the front and bottom of the upper peel film, the three-dimensional moving mechanism A401 is used to move the film-taking suction head 402 to directly above the CCD imaging component 70, so that the CCD imaging component 70 can take pictures and position the film picked up by the first vacuum nozzle 4021. Then, according to its positioning position, the three-dimensional moving mechanism A401 can be used to control the circumferential rotating component 403 to rotate circumferentially to a suitable angle, and then drive the film-taking suction head 402 to move left and right, back and forth, and up and down for a suitable stroke, so as to finally achieve that the film at the front and bottom of the upper peel film picked up by the first vacuum nozzle 4021 is moved and attached to a preset position on the upper surface of the product 2000.

[0127] This allows for more accurate film placement, significantly improving the film application yield.

[0128] Furthermore, in this technical solution, compared with... Figure 1 and Figure 8 As shown, according to one embodiment of the present invention, this application further includes:

[0129] Left-right moving mechanism 80; the left-right moving mechanism 80 is arranged in the left-right direction at the front of the upper end of the machine base 10, and the fixture table 20 is provided on it.

[0130] Film tearing device 90; The film tearing device 90 is located on the left front part of the upper end face of the machine base 10, and includes a three-dimensional moving mechanism B901 that can move left and right, forward and backward, and up and down, and an openable gripper 902 located on the three-dimensional moving mechanism B901.

[0131] The openable gripper 902 is used to grip the rear part of the upper tear film when the jig table 20 is moved to the left by a preset stroke controlled by the left and right moving mechanism 80 so that the jig table 20 is directly below it, so as to tear the upper tear film from the upper part of the film.

[0132] Therefore, it is clear that for the tearing of the upper film, this application provides the film tearing device 90. After the film is pressed and fixed to the upper surface of the product 2000, the front-to-back moving mechanism A602 and the lifting mechanism 603 drive the pressure head component 604 to move away from the fixture table 20. Then, the left-to-right moving mechanism 80 controls the fixture table 20 to move to the left by a preset stroke so that the fixture table 20 is directly below the film tearing device 90. At this time, the three-dimensional moving mechanism B901 of the film tearing device 90 can be used to control its openable and closable gripper 902 to move towards the rear of the upper film, so as to use the openable and closable gripper 902 to grip the rear of the upper film. During the upward movement controlled by the three-dimensional moving mechanism B901, the upper film is torn off from the upper part of the film.

[0133] Thus, even if the upper film is torn off using a mechanical and automated operation, the film tearing efficiency is high.

[0134] Secondly, in specific implementation, refer to Figure 1 As shown, according to one embodiment of the present invention, this application also includes a waste collection box 100 with an open upper portion for collecting the upper film tear.

[0135] The waste collection box 100 is located at the left middle part of the upper end face of the machine base 10;

[0136] Therefore, under the control of the three-dimensional moving mechanism B901, the openable gripper 902 can be moved to directly above the waste collection box 100. At this time, when it releases the upper film it has gripped, the upper film it has gripped can be naturally dropped into the waste collection box 100 so that the upper film is torn off and collected.

[0137] Furthermore, in specific implementation, in accordance with... Figure 1 and Figure 9 As shown, according to an embodiment of the present invention, this application further includes a film conveying device 110 for conveying the film forward to the upper surface of the film taking platform 30;

[0138] The film-applying conveying device 110 is located on the right rear part of the upper end face of the machine base 10, and includes a material rack 1101, a release disc component 1102 installed on the upper part of the material rack 1101 for releasing forward a strip of material with multiple films uniformly adhered to its upper end face along the length direction, a guide rod component 1103 installed in the middle of the material rack 1101, and a winding disc component A1104 installed at the lower part of the material rack 1101 for winding up the strip of waste material; both the release disc component 1102 and the winding disc component A1104 are equipped with a drive component to drive their autonomous rotation.

[0139] Furthermore, the bottom of the film-taking platform 30 is hollowed out. The strip material released forward is guided by the guide rod component 1103, passes from back to front over the upper surface of the film-taking platform 30, and then rotates from the front side of the film-taking platform 30 downward and backward from the bottom of the film-taking platform 30 to the winding reel component A1104.

[0140] Therefore, it can be clearly understood that in the specific application of this application, the release disc component 1102 and the winding disc component A1104 are rotated in opposite directions to realize that the strip material is slowly released forward and the strip waste material is slowly wound backward. During this process, multiple films conveyed forward will be picked up and used one by one.

[0141] Specifically, each time the film at the foremost position is transported to a preset position on the upper surface of the film-taking platform 30, the three-dimensional moving mechanism A401 can be used to control the film-taking suction head 402 to move to a first position, so that the first vacuum nozzle 4021 fits against the upper surface of the pre-placed upper peelable film of the film on the film-taking platform 30, so as to pick up the upper peelable film and the film sheet adhered to its bottom, and then gradually realize the subsequent processes such as bending and shaping the rear of the upper peelable film, film application, film pressing, peeling off the upper peelable film, and collecting the upper peelable film.

[0142] Therefore, this application allows for the continuous application of multiple films to the preset positions on the upper surface of multiple products 2000. After each complete process, the products 2000 fixed on the fixture table 20 can be replaced, enabling automated film application and conveying, automated film removal, automated film application, automated film pressing, and automated film peeling operations in a production line manner. As a result, this application has strong operational continuity and can significantly improve the overall film application efficiency and speed.

[0143] Preferably, in this technical solution, the comparison continues. Figure 1 and Figure 9 As shown, according to one embodiment of the present invention, this application further includes a forward and backward moving mechanism B120 for assisting in peeling off the film;

[0144] The front-to-back moving mechanism B120 is located in the middle right of the upper end face of the machine base 10 along the front-to-back direction; the film taking platform 30 is mounted on the front-to-back moving mechanism B120.

[0145] When the forward and backward moving mechanism B120 drives the film taking platform 30 to move backward, and the release disc component 1102 and the take-up disc component A1104 keep the forward-released and backward-rotating strip material taut, and when the first vacuum nozzle 4021 sucks up the film conveyed to the upper surface of the film taking platform 30 and keeps it stationary, the film can be naturally separated from the strip material.

[0146] Therefore, it is clear that by adding the forward and backward moving mechanism B120, it is possible to assist in peeling off the film, making it easier for the film-removing suction head 402 to pick up the film.

[0147] It should be added that, in specific implementation, it is still necessary to refer to... Figure 1 and Figure 9 As shown, the concave film applicator 1000 provided according to an embodiment of the present invention further includes a vacuum adsorption plate 130 for assisting in peeling off the film.

[0148] The vacuum adsorption plate 130 is horizontally fixed on the material rack 1101 and is flush with the film taking platform 30, and is located at the rear of the film taking platform 30 adjacent to it.

[0149] Therefore, it can be clearly stated that the principle of peeling off the film in this application can be optimized as follows: when the forward and backward moving mechanism B120 drives the film taking platform 30 to move backward, and the vacuum adsorption plate 130 adsorbs the bottom surface of the strip material passing over it and the winding reel component A1104 keeps the strip material rotating backward taut, and when the first vacuum nozzle 4021 holds the film conveyed to the upper surface of the film taking platform 30 and keeps it stationary, the film can be naturally peeled off from the strip material.

[0150] Obviously, in the above operation process, the portion of the strip material that is released forward and not rotated is adsorbed by the vacuum adsorption plate 130, making it less likely to be displaced by the upward suction of the first vacuum nozzle 4021. After the film adsorbed by the first vacuum nozzle 4021 is separated from the strip material, the vacuum adsorption plate 130 can release the vacuum so as not to adsorb the portion of the strip material that is released forward and not rotated, so that the strip material can continue to be conveyed forward and the next film can be conveyed to the upper surface of the film taking platform 30 for the adsorption and peeling of the next film. At this time, the vacuum adsorption plate 130 can be used again to adsorb the portion of the strip material that is released forward and not rotated, so as to assist in the peeling of the corresponding next film.

[0151] Therefore, through the above-mentioned optimized design, this application achieves better reliability in use.

[0152] It should be added that, still in comparison Figure 1 and Figure 9 As shown, in a specific implementation, according to the concave laminating machine 1000 provided in the embodiment of the present invention, the upper surface of the strip material is further provided with an upper protective film for isolating and protecting the multiple films. Based on this, the laminating conveying device 110 of the present application also includes a winding reel component B1105 for winding the protective film. The winding reel component B1105 is fixed on the material rack 1101 and located on the upper part of the release disc component 1102. The winding reel component B1105 also has its own drive component for driving its autonomous rotation.

[0153] In practice, as long as the end of the strip material passes around the lower front part of the film-taking platform 30 and is rotated and fixed to the winding reel component A1104, and the end of the protective film is fixed to the winding reel component B1105, and the winding reel component A1104 and the winding reel component B1105 both maintain the opposite rotation direction to the release reel component 1102, the generated strip waste material can be wound up and the protective film can be torn off and wound up.

[0154] In this way, even though the film conveying device 110 described in this application is powerful and adaptable, it can also tear off and rewind the protective film. Of course, the winding reel component B1105 is not used for strip materials without the protective film.

[0155] Furthermore, in specific implementation, according to the concave film applicator 1000 provided in the embodiment of the present invention, multiple fixture tables 20 can be provided on the left and right moving mechanism 80 to correspondingly fix multiple products 2000, so that multiple products 2000 can be simultaneously applied and removed in a cross manner, thereby improving the overall operation efficiency of this application.

[0156] Furthermore, in the technical solution of this application, the three-dimensional moving mechanism A401, the three-dimensional moving mechanism B901, the circumferential rotating component 403, the openable gripper 902, the first vacuum nozzle 4021, the second vacuum nozzle 4022, the release disc component 1102, the take-up disc component A1104, the take-up disc component B1105, and the vacuum adsorption plate 130 are all common structural components in the prior art, which can be directly purchased and assembled on the market. The lifting component 502, the front and rear moving mechanism A602, the lifting mechanism 603, the left and right moving mechanism 80, and the front and rear moving mechanism B120 are all cylinder drive components, cylinder transmission linear modules, or screw transmission linear modules, etc., which are also common in the prior art. Therefore, their details are not described in detail here.

[0157] Other embodiments are not described here.

[0158] In summary, the concave film applicator 1000 provided in this application, in specific implementation, uses the three-dimensional moving mechanism A401 to control the film-taking suction head 402 to move to the third position, so that the film sheet at the front and bottom of the upper peelable film picked up by the first vacuum nozzle 4021 is driven and applied to the preset position on the surface of the product 2000. The three-dimensional moving mechanism A401 can control the film-taking suction head 402 to move left and right, back and forth, and up and down, so that the film sheet at the front and bottom of the upper peelable film picked up by the first vacuum nozzle 4021 can move flexibly. Within a certain range of movement, it can be moved to the required position to apply the film sheet to the appropriate position on the upper surface of the product 2000. This makes the application flexible and applicable, and can greatly improve the film application efficiency and speed of the product 2000.

[0159] Furthermore, when peeling off the upper film, this application pre-bends and shapes its rear portion upwards and backwards, causing it to curl up. Subsequently, even when pulling off the curled rear portion, this process, whether using a robotic arm or manual pulling, minimizes the risk of touching or damaging the product 2000, and also minimizes the risk of damaging or displacing the applied film. This ensures precise placement and a low defect rate for the film on the product 2000. This application is particularly suitable for applying film to the concave surface of the product 2000, where the upper film can be bent and curled upwards and exposed above the concave surface. Pulling off the film at this point also minimizes the risk of touching the product 2000 and the film.

[0160] Furthermore, by setting the film pressing device 60, after the film is applied to a preset position on the upper surface of the product 2000, the upper layer of the peeling film is still retained on its upper surface. At this time, the first vacuum nozzle 4021 and the second vacuum nozzle 4022 can release the vacuum to loosen the upper layer of the peeling film, and the film taking head 402 can be removed by the three-dimensional moving mechanism A401. Then, the pressing head component 604 can be moved back and forth to above the product 2000 and directly facing the front and bottom of the upper layer of the peeling film in the vertical direction by the forward and backward moving mechanism A602. Then, the lifting mechanism 603 can be used to drive the pressing head component 604 to descend a preset stroke to press the film onto the upper surface of the product 2000. In this way, it is not easy for the film to be torn off together, making the film application more stable and reliable, and its fixation more secure.

[0161] Furthermore, when the lifting mechanism 603 drives the pressure block 6043 of the pressure head component 604 to descend a preset stroke to press the diaphragm onto the upper surface of the product 2000, the pressure buffer component prevents the pressure block 6043 from forcibly pressing the diaphragm onto the upper surface of the product 2000. The pressure buffer component buffers the downward pressure, effectively protecting the diaphragm and the product 2000 from damage, thus improving the reliability of this application.

[0162] Furthermore, by setting the pressure sensor 6053, the downward pressure of the diaphragm can be detected in real time, making the downward pressure data controllable, so that the diaphragm and product 2000 are not easily damaged. By setting the pressure relief spring C6052, the pressure sensor 6053 is well protected and is not easily damaged by hard pushing in the vertical direction.

[0163] Meanwhile, for the tearing of the upper film, this application provides a film-tearing device 90. After the film is pressed and fixed to the upper surface of the product 2000, the front-to-back moving mechanism A602 and the lifting mechanism 603 drive the pressure head component 604 to move away from the fixture table 20. Then, the left-to-right moving mechanism 80 controls the fixture table 20 to move to the left by a preset stroke until the fixture table 20 is directly below the film-tearing device 90. At this time, the three-dimensional moving mechanism B901 of the film-tearing device 90 controls its openable and closable gripper 902 to move towards the rear of the upper film, so as to use the openable and closable gripper 902 to grasp the rear of the upper film. During the upward movement controlled by the three-dimensional moving mechanism B901, the upper film is torn off from the upper part of the film. In this way, the tearing of the upper film is carried out by mechanical automation, resulting in high film-tearing efficiency.

[0164] Furthermore, the concave film applicator 1000 provided in this application is indeed highly practical and has excellent performance, which makes this application inherently valuable for market promotion and will certainly be very popular and effectively popularized.
