Especially for products with a concave structure, after the film is mounted on the concave surface, the relevant tear film is even more difficult to tear off.

[0003] As a matter of fact, whether it is torn off by a robot or by hand, it is easy to touch the product and damage it, and it is also easy to touch the mounted film, making the mounted film also easy to be damaged, and it is also easy to be moved, making the mounting position not accurate enough, resulting in a high defective rate of product film.

[0036] The film conveying device is arranged at the right rear part of the upper end surface of the machine platform, including a material rack, a release plate component installed on the upper part of the material rack for releasing the strip-shaped incoming material with a plurality of films uniformly adhered to the upper end surface along the length direction, a material guide rod component installed in the middle part of the material rack, and a winding plate component A installed at the lower part of the material rack for winding up the strip-shaped waste material;

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

[0039] The front-to-back moving mechanism B is arranged at the right middle part of the upper end surface of the machine table along the front-to-back direction; the film taking platform is mounted on the front-to-back moving mechanism B;

[0040] When the forward and backward moving mechanism B drives the film taking platform to move backward, and the strip-shaped incoming material is released forward and rotated backward under the tension of the release disk component and the winding disk component A, and when the first vacuum suction nozzle sucks the film transported to the upper end surface of the film taking platform, the film is peeled off from the strip-shaped incoming material.

[0041] The beneficial effects of the present invention are:

[0042] First, in the specific implementation of the concave film laminating machine provided by the present application, the present application adopts the three-dimensional moving mechanism A to control the film taking suction head to move to the third position, so that the upper film tearing front part and the film sheet at the bottom sucked by the first vacuum suction nozzle are driven and attached to the preset position on the product surface. The three-dimensional moving mechanism A can control the left and right, front and back, and up and down movements of the film taking suction head, so that the upper film tearing front part and the film sheet at the bottom sucked by the first vacuum suction nozzle can move flexibly, and can be moved to the required position within a certain moving range to attach the film sheet to the matching position on the upper surface of the product, so that the present application has good flexibility and applicability, and can greatly improve the efficiency and speed of product film laminating.

[0043] Second, when the upper tear film is torn off, the present application pre-bends the rear portion of the upper tear film backward and upward to shape it and adsorb it so that it is tilted. Subsequently, it is convenient to pull the rear portion that is bent backward and upward to shape and tilt it to tear it off. In this process, whether it is pulled and torn off by a robot or directly by hand, it is not easy to touch the product, it is not easy to damage the product, and it is not easy to touch the mounted film, so that the mounted film is not easy to be damaged, and it is not easy to be moved, so that the mounting position will be very accurate, so that the defective rate of product film is low. Especially for the concave surface of the product with a concave surface on the upper surface, the present application is more suitable. During operation, the rear portion of the upper tear film can be bent backward and upward to shape and tilt it so that it is exposed outside the upper part of the relevant concave surface. At this time, it is pulled and torn off, and it is also not easy to touch the product and the film.

[0044] Thirdly, by setting the film pressing device, after the film is attached to the preset position on the upper surface of the product, the upper layer of tearing 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 tearing film, and the three-dimensional moving mechanism A can be used to evacuate the film taking suction head. Then, the front-to-back moving mechanism A can be used to control the pressing head component to move back and forth to above the product and face the front part of the upper layer of tearing film and the bottom of the film in the up and down directions, and then the lifting mechanism can be used to drive the pressing head component to descend the preset stroke to press the film to the upper surface of the product. In this way, it is not easy to be torn off together with the film, so that the film can be attached more stably and reliably, and its fixing is also more stable.

[0045] Fourthly, when the lifting mechanism is used to drive the pressure block of the pressure head component to descend a preset stroke to press the diaphragm to the upper surface of the product, due to the provision of the pressure relief member, the pressure block will not rigidly press the diaphragm downward to the upper surface of the product. The pressure relief member is used to buffer the downward pressure, which can well protect the diaphragm and the product from being damaged, so that the present application is more reliable in use.

[0046] Fifth, by setting the pressure sensor, the force with which the diaphragm is pressed down can be detected in real time, so that the pressure strength data can be controlled, so that the diaphragm and the product are not easily damaged. By setting the pressure-relieving spring C, the pressure sensor can be well protected and is not easily damaged by hard force in the up and down directions.

[0047] Sixth point, for the tearing off of the upper layer of tearing film, the present application is provided with the tearing film device. After the film is pressed and fixed to the upper surface of the product, the front-rear moving mechanism A and the lifting mechanism are used to drive the pressure head component to move away from the jig table. Then, the left-right moving mechanism can be used to control the jig table to move to the left by a preset stroke so that the jig table is located directly below the tearing film device. At this time, the three-dimensional moving mechanism B of the tearing film device can be used to control its openable and closable jaws to move toward the rear of the upper layer of tearing film, so as to clamp the rear of the upper layer of tearing film with the openable and closable jaws, and in the process of the three-dimensional moving mechanism B controlling its upward movement, the upper layer of tearing film is torn off from the upper part of the film. In this way, the upper layer of tearing film is torn off by mechanical automation, so that the tearing efficiency is high.

[0086] The concave surface laminating machine 1000 according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

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

[0088] Among them, the fixture table 20 is arranged at the right front part of the upper end surface of the machine 10, and is used to fix the product 2000; the film removal platform 30 is arranged at the right middle part of the upper end surface of the machine 10, and when in use, the film will be pre-set on it; the film removal device 40; the film removal device 40 is arranged on the side of the film removal platform 30, including a three-dimensional moving mechanism A401 that can move left and right, front and back, and up and down, and a film removal suction head 402 arranged on the three-dimensional moving mechanism A401; the film removal suction head 402 is formed into a step shape, so that it has a first vacuum suction nozzle 4021 located at the front and a second vacuum suction nozzle 4022 located at the rear with a height higher than the first vacuum suction nozzle 4021. For details, please refer to Figure 2 and Figure 3As shown; the top film device 50 is arranged beside the film taking platform 30, including a support member 501, a lifting member 502 arranged at the rear of the support member 501, and a top block 503 arranged at the upper part of the lifting member 502 with an initial height equal to or lower than the height of the support member 501. For details, please refer to Figure 4 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 is attached to the upper surface of the upper film tearing front part preset on the film taking platform 30 to suck the upper film tearing front part and the film sheet at the bottom thereof;

[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 suction nozzle 4021 is lifted by the supporting member 501, and the second vacuum suction nozzle 4022 is located directly above the top block 503; the lifting member 502 is used to control the top block 503 to push up the rear part of the upper film tearing layer, so that the rear part of the upper film tearing layer is tilted up and fixed to the lower bottom surface of the second vacuum suction nozzle 4022 and is sucked by the second vacuum suction nozzle 4022;

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

[0092] Based on the above, it can be clearly seen that when the present application is implemented specifically, it is mainly used as a concave film laminating machine 1000.

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

[0094] First, the film taking suction head 402 is controlled to move to the first position through the three-dimensional moving mechanism A401, so that the first vacuum suction nozzle 4021 is attached to the upper surface of the upper film tearing front part of the film pre-set on the film taking platform 30, so as to suck the upper film tearing front part and the film sheet adhered to its bottom.

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

[0096] Thereafter, the lifting member 502 is used to control the top block 503 to push up the rear part of the upper tear film, so that the rear part of the upper tear film is curled up and shaped and adheres to the lower bottom surface of the second vacuum suction nozzle 4022 and is sucked by the second vacuum suction nozzle 4022. In this way, the rear part of the upper tear film is bent backward and upward to be shaped.

[0097] Then, the three-dimensional moving mechanism A401 controls the film taking suction head 402 to move to the third position, so that the upper film tearing front part and the bottom film sheet sucked by the first vacuum suction nozzle 4021 are 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 tear film rear portion, which is bent upward and backward for shaping, can be torn away from the attached film by using a robot or manually pulling the upper tear film rear portion.

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

[0100] On the one hand, the present application adopts the three-dimensional moving mechanism A401 to control the film removing suction head 402 to move to the third position, so that the upper film tearing front part and the film sheet at the bottom sucked by the first vacuum suction nozzle 4021 are driven and attached to the preset position on the surface of the product 2000. The three-dimensional moving mechanism A401 can control the left and right, front and back, and up and down movements of the film removing suction head 402, so that the upper film tearing front part and the film sheet at the bottom sucked by the first vacuum suction nozzle 4021 can move flexibly, and can be moved to the required position within a certain moving range to attach the film sheet to the matching position on the upper surface of the product 2000, so that the present application has good flexibility and applicability, and can greatly improve the efficiency and speed of film sticking of the product 2000.

[0101] On the other hand, when tearing off the upper tear film, the present application pre-bends the rear portion thereof backward and upward to shape it and adsorb it so that it is lifted up. Subsequently, it is convenient to pull the lifted rear portion that is bent backward and upward to shape it to be pulled up to tear it off. In this process, no matter whether a robot is used or the rear portion is directly pulled and torn off by hand, it is not easy to touch the product 2000, it is not easy to damage the product 2000, and it is not easy to touch the mounted film sheet, so that the mounted film sheet is not easy to be damaged and not easy to be shifted, so that the mounting position is very precise, so that the defective rate of the film of the product 2000 is low.

[0102] Moreover, the present application is more applicable, especially when it is necessary to apply film to the concave surface of the product 2000 with a concave surface on the upper surface. During operation, the rear part of the upper tear film can be bent backward and upward to be shaped and lifted up to be exposed outside the upper part of the relevant concave surface. At this time, it is pulled and torn off, and it is also not easy to touch the product 2000 and the film.

[0103] Furthermore, through the above-mentioned optimized design, the overall structure of the present application is highly practical and has good use effect.

[0104] Further, in the specific implementation, specific, reference Figure 5 , Figure 6 and Figure 7 As shown, according to one embodiment of the present invention, the present application further comprises a lamination device 60;

[0105] The laminating device 60 is mounted on the upper part of the fixture table 20, and includes a fixed frame 601, a front-to-back moving mechanism A602 disposed on the fixed frame 601, a lifting mechanism 603 disposed on the front-to-back moving mechanism A602, and a pressing head component 604 disposed 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 to above the product 2000 and faces the front part of the upper tear film and the bottom film in the up and down directions, 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 the preset position on the upper surface of the product 2000, the upper surface of the film still retains the upper tear film. At this time, the first vacuum nozzle 4021 and the second vacuum nozzle 4022 can release the vacuum to loosen the upper tear film, and the three-dimensional moving mechanism A401 can be used to evacuate the film taking suction head 402. Then, the front-to-back moving mechanism A602 can be used to control the pressing head component 604 to move back and forth to above the product 2000 and face the front part of the upper tear film and the bottom of the film in the up and down directions, and then the lifting mechanism 603 can be used to drive the pressing head component 604 to descend the preset stroke to press the film to the upper surface of the product 2000.

[0108] Subsequently, when the film is pressed and fixed and is not easy to fall off the surface of the product 2000, a robot or manual pulling can be used to pull the rear part of the upper tear film that is bent backward and upward to tear it off from the attached film.

[0109] In this way, the film is not easily torn off, so that the film is more stably and reliably mounted and its fixing is more firmly established.

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

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

[0112] Therefore, when the lifting mechanism 603 is used to drive the pressure block 6043 of the pressure head component 604 to descend a preset stroke to press the diaphragm to the upper surface of the product 2000, due to the provision of the pressure relief member, the pressure block 6043 will not rigidly press the diaphragm downward to the upper surface of the product 2000. The pressure relief member is used to buffer the downward pressure, so that the diaphragm and the product 2000 can be well protected and are not easily damaged, so that the present application is more reliable in use.

[0113] And preferably, in this technical solution, continue to control Figure 6 and Figure 7 As shown, according to one embodiment of the present invention, the pressure head component 604 further includes a left supporting plate 6044, a right supporting 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 fixedly mounted on the left and right sides of the lower bottom surface of the upper connecting plate 6041 in the vertical direction; the left support plate 6044 has a left bracket 60441 at the bottom thereof for supporting the left end of the lower connecting plate 6042; the right support plate 6045 has a right bracket 60451 at the bottom thereof for supporting the right end of the lower connecting plate 6042;

[0115] In addition, the left slide rail 6046 is vertically fixed on the right end surface of the left support plate 6044, and a compression spring A6050 is fixed between the bottom of the left slide rail 6046 and the left end of the lower connecting plate 6042; the right slide rail 6047 is vertically fixed on the left end surface of the right support plate 6045, and a compression spring B6051 is fixed between the bottom of the right slide rail 6047 and the right end of the lower connecting plate 6042; the compression spring A6050 and the compression spring B6051 constitute the compression component, and they are both kept in a natural state at the beginning.

[0116] Based on this, in the present application, the left slider 6048 and the right slider 6049 are correspondingly mounted in the left slide rail 6046 and the right slide rail 6047 and can slide up and down, and the bottoms thereof are connected to the upper end surface of the lower connecting plate 6042 .

[0117] In this regard, it is clear that

[0118] On the one hand, since the left support plate 6044 has a left bracket 60441 at the bottom for supporting the left end of the lower connecting plate 6042, and the right support plate 6045 has a right bracket 60451 at the bottom for supporting the right end of the lower connecting plate 6042, the lower connecting plate 6042 is initially supported by the left bracket 60441 and the right bracket 60451, so that the compression relief spring A6050 and the compression relief spring B6051 can remain in a natural state without being pulled down by the lower connecting plate 6042, so that they can both maintain elastic force well and have a long service life.

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

[0120] Furthermore, through the above-mentioned optimization design, the overall use effect of the present application can be effectively improved.

[0121] Furthermore, in the specific implementation, we should 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] Among them, a fixing groove A60421 is opened downwardly in the middle of the upper end surface of the lower connecting plate 6042, and a fixing groove B60411 is opened upwardly in the middle of the lower bottom surface of the upper connecting plate 6041 and is opposite to the fixing groove A60421; the pressure sensor 6053 is fixed in the fixing groove A60421, and the pressure relief spring C6052 is naturally arranged between the top of the pressure sensor 6053 and the lower bottom surface of the upper connecting plate 6041, and the upper end of the pressure relief spring C6052 is connected to a connecting block 60521 inserted into the fixing groove B60411.

[0123] From this, it can be clearly seen that by providing the pressure sensor 6053, the force with which the diaphragm is pressed down can be detected in real time, so that the downward pressure strength data can be controlled, so that the diaphragm and the product 2000 are not easily crushed. By providing the pressure-relieving spring C6052, the pressure sensor 6053 can be well protected and is not easily damaged by hard force in the up and down directions.

[0124] In addition, in the specific implementation, the control Figure 1 As shown, according to one embodiment of the present invention, the present application further includes a CCD photographing component 70 for photographing and positioning the film sucked by the first vacuum nozzle 4021;

[0125] The CCD camera component 70 is disposed upward on the upper end surface of the machine 10 and is located beside the film taking platform 30; based on this, Figure 2 and Figure 3 As shown, the film removal device 40 described in the present application also includes a circumferential rotating component 403 which is arranged on the three-dimensional moving mechanism A401 and can move left and right, front and back, and up and down under the control of the three-dimensional moving mechanism, and the film removal suction head 402 is arranged at the bottom of the circumferential rotating component 403.

[0126] In this regard, it should be explained that after the first vacuum suction nozzle 4021 sucks the upper film tearing front part and the film sheet at the bottom, the three-dimensional moving mechanism A401 is also used to drive the film taking suction head 402 to move to the top of the CCD shooting component 70, so that the film sheet sucked by the first vacuum suction nozzle 4021 can be photographed and positioned by the CCD shooting component 70, and 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, front and back, and up and down for a suitable stroke, so as to finally realize that the upper film tearing front part and the film sheet at the bottom sucked by the first vacuum suction nozzle 4021 are driven and attached to the preset position on the upper surface of the product 2000.

[0127] In this way, the film mounting position can be made more accurate, so that the film mounting yield can be greatly improved.

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

[0129] A left-right moving mechanism 80; the left-right moving mechanism 80 is arranged in the left-right direction on the front of the upper end of the machine table 10, and the fixture table 20 is arranged thereon;

[0130] The film-tearing device 90 is disposed at the left front portion of the upper end surface of the machine platform 10, and includes a three-dimensional moving mechanism B901 that can move left and right, front and back, and up and down, and an openable and closable clamping claw 902 disposed on the three-dimensional moving mechanism B901;

[0131] The openable and closable clamping jaw 902 is used to clamp the rear portion of the upper tear film when the left-right moving mechanism 80 controls the jig table 20 to move to the left by a preset stroke so that the jig table 20 is located directly below it, so as to tear the upper tear film off from the upper portion of the film sheet.

[0132] Therefore, it can be clearly seen that for the tearing off of the upper layer of tearing film, the present application is provided with the tearing film device 90. After the film is pressed and fixed to the upper surface of the product 2000, the front-rear moving mechanism A602 and the lifting mechanism 603 are used to drive the pressure head component 604 to move away from the jig table 20. Then, the left-right moving mechanism 80 can be used to control the jig table 20 to move to the left by a preset stroke so that the jig table 20 is located directly below the tearing film device 90. At this time, the three-dimensional moving mechanism B901 of the tearing film device 90 can be used to control its openable and closable jaws 902 to move toward the rear part of the upper layer of tearing film, so as to clamp the rear part of the upper layer of tearing film with the openable and closable jaws 902, and in the process of the three-dimensional moving mechanism B901 controlling its upward movement, the upper layer of tearing film is torn off from the upper part of the film.

[0133] In this way, the upper film can be torn off by mechanical automation, so that the film tearing efficiency is high.

[0134] Again, in the specific implementation, Figure 1 As shown, according to one embodiment of the present invention, the present application further comprises a waste collection box 100 with an open top for collecting the upper torn film;

[0135] Wherein, the waste collection box 100 is arranged at the left middle part of the upper end surface of the machine platform 10;

[0136] Therefore, under the control of the three-dimensional moving mechanism B901, the openable and closable clamping jaws 902 can be driven to the top of the waste collection box 100. At this time, when the clamped upper layer of tear film is released, the clamped upper layer of tear film can be naturally dropped into the waste collection box 100 so that the upper layer of tear film can be torn off and collected.

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

[0138] Among them, the film conveying device 110 is arranged at the right rear part of the upper end surface of the machine 10, including a material rack 1101, a release disk component 1102 installed on the upper part of the material rack 1101 for releasing the strip-shaped incoming material with multiple films evenly adhered to the upper end surface along the length direction, a material guide rod component 1103 installed in the middle part of the material rack 1101 and a winding disk component A1104 installed at the lower part of the material rack 1101 for winding up the strip-shaped waste material; the release disk component 1102 and the winding disk component A1104 are both equipped with a driving part for driving their autonomous rotation.

[0139] In addition, the bottom of the film taking platform 30 is hollowed out, and the strip-shaped incoming material released forward is guided by the material guide rod component 1103, passes through the upper end surface of the film taking platform 30 from back to front, and rotates from the front side of the film taking platform 30 downward and then backward from the bottom of the film taking platform 30 to the winding disk component A1104.

[0140] Therefore, it is clear that when the present application is used in practice, the release disk component 1102 and the winding disk component A1104 are rotated in opposite directions to realize that the incoming strip material is slowly released forward and the waste strip material is slowly wound backward. In this process, multiple films transported forward will be sucked in and used one by one.

[0141] Specifically, each time when the film located at the front is transported to the preset position on the upper end 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 the first position, so that the first vacuum suction nozzle 4021 is in contact with the upper surface of the front part of the upper layer of film tearing of the film preset on the film taking platform 30, so as to absorb the front part of the upper layer of film tearing and the film sheet adhered to its bottom, and then gradually realize the steps of bending backward and upward to shape and curling the rear part of the upper layer of film tearing, mounting of the film sheet, film pressing, tearing off of the upper layer of film tearing and collection of the upper layer of film in subsequent processes.

[0142] Therefore, the present application can be used to continuously attach multiple films to the preset positions on the surfaces of multiple products 2000 that need to be attached. After each entire process flow is completed, the product 2000 fixed on the fixture table 20 can be replaced, so that the present application can perform assembly-line-style automated film conveying operations, automated film taking operations, automated film top operations, automated film pressing operations, and automated film tearing operations, so that the operations of the present application have strong continuity and sustainability, which can indeed greatly improve the overall film sticking efficiency and speed.

[0143] Preferably, in this technical solution, continue to control Figure 1 and Fig. 9 As shown, according to one embodiment of the present invention, the present 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 arranged at the right middle part of the upper end surface of the machine 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 disk component 1102 and the winding disk component A1104 always keep the strip material released forward and rotated backward taut, and when the first vacuum suction nozzle 4021 sucks the film conveyed to the upper end surface of the film taking platform 30 and keeps it still, it can be achieved that the film and the strip material can be naturally separated.

[0146] In this regard, it is clear that by adding the forward and backward moving mechanism B120, it is possible to assist in peeling off the film, so that the film removal suction head 402 can remove the film more easily when sucking the film.

[0147] It should be added that in the specific implementation, it is still necessary to refer to Figure 1 and Fig. 9 As shown, according to the concave film laminating machine 1000 provided in an embodiment of the present invention, the present application also 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 , flush with the film taking platform 30 , and is adjacent to the film taking platform 30 and arranged at the rear of the film taking platform 30 .

[0149] From this, it can be clearly seen that the principle of peeling off the film in the present 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 lower bottom surface of the strip material passing thereon and the winding disk component A1104 always keeps the strip material rotating backward taut, and when the first vacuum suction nozzle 4021 adsorbs the film conveyed to the upper end surface of the film taking platform 30 and keeps it still, it can be achieved that the film and the strip material can be naturally peeled off.

[0150] Obviously, for the above operation process, the part of the strip-like incoming material that is released forward and not rotated is partially adsorbed by the vacuum adsorption plate 130, so that it is not easily displaced by the upward suction of the first vacuum suction nozzle 4021. After the film sucked by the first vacuum suction nozzle 4021 is peeled off from the strip-like incoming material, the vacuum adsorption plate 130 can release the vacuum so as not to adsorb the part of the strip-like incoming material that is released forward and not rotated, so that the strip-like incoming material continues to be conveyed forward and the next film is conveyed to the upper end surface of the film taking platform 30 to prepare for the suction and peeling of the next film. At this time, the vacuum adsorption plate 130 can be used to adsorb the part of the strip-like incoming material that is released forward and not rotated again, so as to assist in the peeling of the corresponding next film.

[0151] Therefore, through the above-mentioned optimized design, the reliability of the present application is improved.

[0152] It is further necessary to add that Figure 1 and Fig. 9 As shown, in a specific implementation, according to the concave film laminating machine 1000 provided in an embodiment of the present invention, the upper surface of the strip-shaped incoming material is also provided with an upper protective film for isolating and protecting a plurality of the films. Based on this, the film laminating conveying device 110 described in the present application also includes a winding disk component B1105 for winding up the protective film. The winding disk component B1105 is fixed on the material rack 1101 and is located on the upper part of the release disk component 1102, and the winding disk component B1105 also has a driving member for driving its autonomous rotation.

[0153] During implementation, as long as the end of the incoming strip material is allowed to bypass the front lower part of the film taking platform 30 and is rotated and fixed to the winding disk component A1104, and the end of the protective film is fixed to the winding disk component B1105, and the winding disk component A1104 and the winding disk component B1105 are kept in the opposite direction of rotation to the release disk component 1102, the formed strip waste material can be wound up and the protective film can be torn off and wound up.

[0154] In this way, the film conveying device 110 described in the present application is powerful and has strong adaptability, and can also tear off and reel up the protective film. Of course, for the strip material without the protective film, the reel component B1105 is not used.

[0155] It is further necessary to add that, in a specific implementation, according to the concave film laminating machine 1000 provided in an embodiment of the present invention, a plurality of the jig tables 20 can be arranged on the left-right moving mechanism 80 to facilitate the corresponding fixing of a plurality of products 2000, so that the film laminating and film tearing can be performed synchronously on the plurality of products 2000 in a cross-wise manner, so as to make the overall operation effect of the present application higher.

[0156] Furthermore, in the technical solution of the present application, the three-dimensional moving mechanism A401, the three-dimensional moving mechanism B901, the circumferential rotating member 403, the openable and closable clamping jaws 902, the first vacuum suction nozzle 4021, the second vacuum suction nozzle 4022, the release disk member 1102, the winding disk member A1104, the winding disk member B1105 and the vacuum adsorption plate 130 are all common structural parts in the prior art, which can be directly purchased and assembled on the market for use. The lifting member 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 parts, cylinder-driven linear modules or screw-driven linear modules, which are also common in the prior art, so their details will not be described in detail here.

[0157] Other embodiments and the like are not described here by way of example.

[0158] To summarize, the concave film laminating machine 1000 provided by the present application, during specific implementation, adopts the three-dimensional moving mechanism A401 to control the film taking suction head 402 to move to the third position, so that the upper film tearing front part and the film sheet at the bottom sucked by the first vacuum suction nozzle 4021 are driven and attached to the preset position on the surface of the product 2000. The three-dimensional moving mechanism A401 can control the left and right, front and back, and up and down movement of the film taking suction head 402, so that the upper film tearing front part and the film sheet at the bottom sucked by the first vacuum suction nozzle 4021 can move flexibly, and can be moved to the required position within a certain moving range to attach the film sheet to the matching position on the upper surface of the product 2000, so that the present application has good flexibility and applicability, and can greatly improve the film laminating efficiency and speed of the product 2000.

[0159] Furthermore, when the upper tear film is to be torn off, the present application pre-bends the rear portion of the upper tear film backward and upward to shape it and adsorb it so that it is tilted. Subsequently, it is convenient to pull the rear portion that is bent backward and upward to shape and tilt it to tear it off. In this process, whether it is pulled and torn off by a robot or directly by hand, it is not easy to touch the product 2000, it is not easy to damage the product 2000, and it is not easy to touch the attached film, so that the attached film is not easy to be damaged, and it is not easy to be moved, so that the attachment position will be very accurate, so that the defective rate of the product 2000 is low. In particular, when it is necessary to attach a film to the concave surface of the product 2000 with a concave surface on the upper surface, the present application is more suitable. During operation, the rear portion of the upper tear film can be bent backward and upward to shape and tilt it so that it is exposed outside the upper part of the relevant concave surface. At this time, it is pulled and torn off, and it is also not easy to touch the product 2000 and the film.

[0160] In addition, by setting up the film pressing device 60, after the film is attached to the preset position on the upper surface of the product 2000, the upper layer of tear 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 tear film, and the three-dimensional moving mechanism A401 can be used to evacuate the film taking suction head 402, and then the front-to-back moving mechanism A602 can be used to control the pressing head component 604 to move forward and backward to above the product 2000 and face the front part of the upper layer of tear film and the bottom of the film in the up and down directions, and then the lifting mechanism 603 can be used to drive the pressing head component 604 to descend the preset stroke to press the film to the upper surface of the product 2000. In this way, it is not easy to be torn off together with the film, so that the film can be attached more stably and reliably, and its fixing is also more stable.

[0161] Furthermore, when the lifting mechanism 603 is used to drive the pressure block 6043 of the pressure head component 604 to descend a preset stroke to press the diaphragm to the upper surface of the product 2000, due to the provision of the pressure relief member, the pressure block 6043 will not rigidly press the diaphragm downward to the upper surface of the product 2000. The pressure relief member is used to buffer the downward pressure, which can well protect the diaphragm and the product 2000 from being damaged, so that the present application is more reliable in use.

[0162] Again, by setting the pressure sensor 6053, the force with which the diaphragm is pressed down can be detected in real time, so that the pressure strength data can be controlled, so that the diaphragm and the product 2000 are not easily damaged. By setting the pressure-relieving spring C6052, the pressure sensor 6053 can be well protected and is not easily damaged by hard force in the up and down directions.

[0163] At the same time, for the tearing off of the upper layer of tearing film, the present application is provided with the tearing film device 90. After the film is pressed and fixed to the upper surface of the product 2000, the front-rear moving mechanism A602 and the lifting mechanism 603 are used to drive the pressure head component 604 to move away from the jig table 20. Then, the left-right moving mechanism 80 can be used to control the jig table 20 to move to the left by a preset stroke so that the jig table 20 is located directly below the tearing film device 90. At this time, the three-dimensional moving mechanism B901 of the tearing film device 90 can be used to control its openable and closable jaws 902 to move toward the rear part of the upper layer of tearing film, so as to clamp the rear part of the upper layer of tearing film with the openable and closable jaws 902, and in the process of the three-dimensional moving mechanism B901 controlling its upward movement, the upper layer of tearing film is torn off from the upper part of the film. In this way, the upper layer of tearing film can be torn off by mechanical automation, so that the tearing efficiency is high.

[0164] Furthermore, the concave film laminating machine 1000 provided by the present application is indeed extremely practical and has excellent use effect, which makes the present application bound to have a good market promotion value, and the present application is bound to be very popular and will be effectively popularized.
