DETAILED DESCRIPTION

[0025] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0026] refer to Figure 1-Figure 9 , including a machine 1, the top of the machine 1 is connected with a grab arm 2 through a vertical beam for transverse sliding, the grab arm 2 transports the mobile phone cover plate on the surface of the upper and lower material belts 3 to the surface of the support assembly 6, the support assembly 6 slides longitudinally on the top of the machine 1 and transports the cover plate to the position of the side swing coating mechanism 9, the side swing coating mechanism 9 is arranged between two groups of placement plates 4, the placement plates 4 are fixed on the top of the machine 1, the inner side of the placement plates 4 is movably connected with two groups of film material rollers, and the film material rollers are rotatably arranged between the placement plates 4 through the film feeding mechanism 5; The film feeding mechanism 5 includes a main tooth 52 and a secondary tooth 53, which mesh with each other. The main tooth 52 is fixed to the output shaft of the servo motor 51. Two sets of film material rollers are respectively connected with the output shaft of the servo motor 51 and the driving shaft 56. The driving shaft 56 is connected with the secondary tooth 53 through a transmission belt assembly 55. The secondary tooth 53 is movably arranged on the surface of the placement plate 4 through a separation assembly 57, and the movable circle center of the secondary tooth 53 coincides with the axis center of the driving shaft 56. The side-swing coating mechanism 9 includes an electric cylinder 91, a re-pressing assembly 98 and a swing plate 99. The two sides of the swing plate 99 are movably arranged between the two groups of placement plates 4 through a rotating pin, and the rotating pin is located at one end of the side of the swing plate 99. The other end of the side of the swing plate 99 is connected to the electric cylinder 91 through a push rod 96. The electric cylinder 91 drives the swing plate 99 to swing between the two groups of placement plates 4.

[0027] In this embodiment, first, the mobile phone cover will be driven from the upper and lower material belts 3 to the bottom of the grabbing arm 2. The upper and lower material belts 3 can be composed of a conveyor belt. At this time, the grabbing arm 2 moves downward to grab the mobile phone cover. The grabbing can be achieved by a suction cup or a clamp. Under the lateral movement of the grabbing arm 2, the mobile phone cover is brought to the surface of the support assembly 6, and is brought by the support assembly 6 to the position of the side swing coating mechanism 9 in the placement plate 4 for coating. After the coating is completed, the support assembly 6 retreats, and the grabbing arm 2 grabs the mobile phone cover to the surface of the upper and lower material belts 3 again to realize unloading. Two groups of film rollers are arranged on the inner side of the placement plate 4, respectively realizing film feeding and waste collection, and the servo motor 51 can directly drive a single group of film rollers to rotate, and at the same time, the main teeth 52 are fixed on the output shaft of the servo motor 51, and the meshing effect of the main teeth 52 and the auxiliary teeth 53 can realize that the auxiliary teeth 53 drive the driving shaft 56 to rotate through the transmission belt assembly 55, and the driving shaft 56 is connected to the other group of film rollers, thereby achieving better transmission synchronization, ensuring the tension of the film and the feeding and collection, and effectively improving practicality; Furthermore, the separation component 57 can drive the auxiliary teeth 53 to move on the surface of the placement plate 4, so that the auxiliary teeth 53 can be separated from the main teeth 52. At the same time, the rotation center of the separation component 57 coincides with the axis of the driving shaft 56, which effectively ensures the tensioning effect of the transmission belt component 55. When the auxiliary teeth 53 are separated from the main teeth 52, the transmission of the servo motor 51 will only drive a single group of film rollers to rotate, and cooperate with the subsequent flipping of 99 to prevent the film from being damaged due to excessive force caused by the rotation of 99. It is worth noting here that a single group of film rollers that are disconnected from the output shaft of the servo motor 51 can be connected to the placement plate 4 by setting a damping sleeve to ensure that the film roller will not rotate on its own. After the support assembly 6 drives the mobile phone cover to align with the side swing coating mechanism 9, the electric cylinder 91 can directly drive 99 to flip between the two sets of placement plates 4. At this time, the end of the film will also rotate, so that the end of the film is aligned with the end of the collecting cover. This effect is helpful for monitoring the monitoring equipment, thereby effectively ensuring the docking accuracy.

[0028] refer to Figure 2 and Figure 3 The support platform assembly 6 includes a sliding platform 61 and a flap support platform 62. The bottom of one side of the flap support platform 62 is rotatably arranged above the sliding platform 61 through an axle pin. An inclined groove 63 is provided at the bottom of the flap support platform 62. A support rod 64 is provided at a horizontal position of the placement plate 4 near the inclined groove 63. A first monitoring device 7 is fixedly connected to a horizontal position of one side of the sliding platform 61 near the top of the flap support platform 62.

[0029] In this embodiment, the mobile phone cover is brought to the surface of the flip-plate support 62 by the grabbing arm 2. Here, the surface of the flip-plate support 62 can also be provided with an external suction device to ensure the accurate fit and stability of the mobile phone cover and the flip-plate support 62. Subsequently, the sliding table 61 is longitudinally moved on the top of the machine 1 by the servo transmission component, driving the mobile phone cover to move; A bevel groove 63 is provided on the bottom surface of the flap support 62, and a support rod 64 is provided at a horizontal height position close to the bevel groove 63 of the mounting plate 4. When the bevel groove 63 contacts the support rod 64, the continuous driving effect will cause the flap support 62 to be pushed by the support rod 64 and flipped on the top of the sliding platform 61, thereby driving the mobile phone cover to flip. At this time, the end of the mobile phone cover will change its angular position, so as to facilitate the first monitoring device 7 to monitor and observe, and facilitate the subsequent docking with the end of the film, thereby improving the docking accuracy of the automation equipment and effectively ensuring the coating quality.

[0030] refer to Figure 5 , Figure 8 and Fig. 9 The output end of the electric cylinder 91 is fixedly connected with a pull rod 92, a foot plate rod 93 is fixed on the surface of the pull rod 92, a slider 94 is telescopically slidable on one side of the foot plate rod 93, and a resisting spring 95 is also arranged between the foot plate rod 93 and the slider 94. One side of the slider 94 is movably connected with the shaft hole at the bottom of the push rod 96 through an axle pin, and the top of the push rod 96 is movably connected with the swing plate 99 through the shaft hole, and a limited sliding groove is provided at the position of the placement plate 4 near the slider 94.

[0031] In this embodiment, after the support assembly 6 drives the mobile phone cover to move to the specified position, the electric cylinder 91 is driven to pull the foot rod 93 to one side through the pull rod 92. The output between the foot rod 93 and the slider 94 is through-slidingly connected, but a resistance spring 95 is also arranged between the foot rod 93 and the slider 94. In this way, under the elastic action of the resistance spring 95, the slider 94 is effectively driven to displace on the side of the placement plate 4. At this time, the movement of the slider 94 will push the bottom of the push rod 96, and the top of the push rod 96 will push 99, and 99 will be limited to rotate between the care placement plates 4, so that 99 will flip over, thereby realizing the flipping of the end of the film and aligning it with the end of the mobile phone cover. This alignment effect is monitored by the second monitoring device 8. If the alignment effect is not ideal, actual compensation can be made by controlling the movement of the support assembly 6.

[0032] refer to Figure 8 and Fig. 9The re-pressing assembly 98 includes a docking block 981, a pull plate 982 and a side foot plate 983. The docking block 981 and the side foot plate 983 are respectively movably connected to the two sides of the pull plate 982 through axle pins. The side foot plate 983 and the pull plate 982 are movably connected at one side of the axle pin at the movably connected position. The film coating roller 985 is located above the end position of the swing plate 99. The top of the side foot plate 983 is elastically connected to the placement plate 4 through a tension spring 984. The top of the placement plate 4 is also fixedly provided with a second monitoring device 8 near the film coating roller 985. The placement plate 4 is also provided with a limiting slide groove near the movable position of the side foot plate 983 and the pull plate 982. A clamping block 97 is fixedly connected to one side of the pull rod 92. The docking block 981 is slidably arranged on the side of the placement plate 4, and the docking block 981 and the clamping block 97 are aligned with each other.

[0033] In this embodiment, after the mobile phone cover is completely aligned with the film, the continuous pulling of the pull rod 92 can drive the card block 97 to engage with the docking block 981, and the slider 94 is restricted by the side groove of the placement plate 4 and cannot move. The movement effect of the pull rod 92 and the foot plate rod 93 is converted into squeezing the resistance spring 95 to cause it to elastically deform. During the elastic deformation of the resistance spring 95, the force of the docking block 981 occurs in the displacement of the side of the placement plate 4. One side of the docking block 981 is movably connected to the pull plate 982. The pull plate 982 is forced to pull the side foot plate 983 to move downward on the side of the placement plate 4, and synchronously drives the coating roller 985 to align with the end position of the film, thereby facilitating the subsequent coating operation and preventing the film from separating or detaching from the mobile phone cover. The side foot plate 983 will pull the tension spring 984 during the downward movement, and the deformation of the tension spring 984 provides an upward pulling force to the side foot plate 983, so that during the resetting process of the pull rod 92, the side foot plate 983 can also drive the laminating roller 985 to normally reset upward.

[0034] refer to Figure 5 One side of the swing plate 99 and the bottom of the side are movably connected with guide rollers through side plates. The other side of the swing plate 99 is in an inclined shape. The films on the surfaces of the two groups of film material rollers are connected to each other and bypass the upper and lower end surfaces of the swing plate 99 respectively.

[0035] In this embodiment, the setting of the guide roller effectively prevents the film from being stretched or damaged by the shear force during the flipping process of 99, and the film passes through the upper and lower end surfaces of 99 and separates at one side of 99, thereby unfolding the film adhesion position, which is also the position where it docks with the end of the mobile phone cover.

[0036] refer to Figure 5 and Figure 7The transmission belt assembly 55 is connected to the driving shaft 56 and the swing shaft 54 ​​through the pulleys on both sides. The auxiliary teeth 53 are located below one side of the main teeth 52, and the auxiliary teeth 53 are fixed on the surface of the swing shaft 54. A separation assembly 57 is also provided on one side of the transmission belt assembly 55. The separation assembly 57 includes a connecting plate 571 and a sliding groove 572. The sliding groove 572 is provided at the bottom of the connecting plate 571. A push block 573 is slidably provided in the sliding groove 572. The push block 573 moves up and down on one side of the placement plate 4 through an electric rod. The top of the connecting plate 571 is movably connected to the driving shaft 56 and the swing shaft 54 ​​through shaft holes on both sides. An arc groove 58 is provided on the surface of the placement plate 4 near the swing shaft 54. The center of the arc groove 58 coincides with the center of the driving shaft 56. The push block 573 drives the connecting plate 571 to rotate with the driving shaft 56 as the center and is provided on the side of the placement plate 4.

[0037] In this embodiment, the two film rollers arranged between the two sets of placement plates 4 are rotated by the film feeding mechanism 5 to realize the feeding of the film. Specifically, after being driven, the servo motor 51 can directly drive a single set of film rollers to rotate to reel up the waste film. At the same time, under the meshing of the main teeth 52, the auxiliary teeth 53 are forced to drive the swing shaft 54 ​​to rotate. One side of the swing shaft 54 ​​directly drives the driving shaft 56 to rotate through the transmission belt assembly 55, thereby realizing the control of the unloading operation of another set of film rollers, achieving a higher degree of synchronization as a whole, and preventing the occurrence of loose film and the like. In the above-mentioned 99 flipping process, the flipping effect will pull the film. At this time, in order to prevent the film from being damaged by tension, it is necessary to realize the unwinding operation of the winding film material roller, and the end positions of the swing shaft 54 ​​and the driving shaft 56 are movably connected with the connecting plate 571. The connecting plate 571 can not only provide a good supporting tension for the transmission belt assembly 55, but also a sliding groove 572 is provided at the bottom of the connecting plate 571. The sliding groove 572 is slidably connected to the push block 573, and the push block 573 is realized by the electric rod at the bottom. Move, so that when the push block 573 moves downward, the connecting plate 571 as a whole can be pulled. At this time, the connecting plate 571 as a whole swings with the active shaft 56 as the center, driving the swing shaft 54 ​​to slide in the arc groove 58, and at the same time, the auxiliary tooth 53 will be separated from the main tooth 52, so that the servo motor 51 can be reversed to realize the discharge operation, and the other set of film rollers and the placement plate 4 can be prevented from rotating by damping sleeves and other equipment. The flipping of 99 pulls the two sets of rollers to realize the discharge, thereby preventing the film from being strained.

[0038] Working principle: First, the upper and lower material belts 3 transport the mobile phone cover to the bottom of the grabbing arm 2, the upper and lower material belts 3 grab the mobile phone cover, and bring the mobile phone cover to the surface of the flip-plate support 62, the sliding platform 61 is driven by the servo transmission component to move longitudinally, so that the flip-plate support 62 drives the mobile phone cover to move to a position close to the two sets of placement plates 4, because the placement plate 4 is close to the horizontal height position of the inclined groove 63 at the bottom of the flip-plate support 62, the support rod 64 is pushed by the support rod 64 on the inclined groove 63, and the flip-plate support 62 as a whole drives the mobile phone cover to flip at a small angle; Then the electric cylinder 91 on the side of the placement plate 4 is driven, and the electric cylinder 91 directly drives the foot plate rod 93 and the block 97 to move under the connection of the pull rod 92. On the one hand, the foot plate rod 93 is elastically telescopically connected to the slider 94 through the resistance spring 95, so that the slider 94 will be pushed first under the elastic resistance, thereby driving the push rod 96 to move downward. The top of the push rod 96 is movably connected to 99, and the bottom of the push rod 99 is subjected to the thrust of the push rod 96, so that 99 swings with one end and the rotation position of the placement plate 4 as the center of the circle, driving the film to align with the mobile phone cover in the inclined state. At this time, the first monitoring device 7 and the second monitoring device 8 are used for monitoring. If alignment is not possible, the alignment effect can be changed by driving the actual position of the flap support 62. Before 99 flips over, the film feeding mechanism 5 on the side of the placement plate 4 will be started, wherein the bottom of the push block 573 in the separation component 57 is provided with an electric rod, and the push block 573 is pulled downward and slides inside the sliding groove 572 at the same time, so that the connecting plate 571 as a whole swings around the driving shaft 56 as the center, thereby driving the auxiliary teeth 53 on the surface of the swing shaft 54 ​​to separate from the main teeth 52 on the output shaft of the servo motor 51, and then the servo motor 51 can be reversed to realize the discharge operation of the film material roller, so that the reversal of 99 will not damage the film; After the film is aligned with the mobile phone cover, the pull rod 92 is continuously pulled by the electric cylinder 91, so that the foot rod 93 continuously pushes the slider 94. The slider 94 is restricted by the side slide groove of the placement plate 4, so that the resistance spring 95 is elastically deformed and effectively stabilized 99 under the action of the elastic force. At the same time, the block 97 will be engaged with the docking block 981 in the re-pressing component 98, so that the docking block 981 moves. The same as the function of the push rod 96, the docking block 981 will drive the side foot plate 983 to move downward through the pull plate 982, so that the coating roller 985 is aligned with the top of the film. At this time, the sliding table 61 moves in the opposite direction, and the servo motor 51 also rewinds the film material roller again, so that the film is separated from the waste material, and is pressed against the surface of the mobile phone cover by the coating roller 985, until the flap support 62 completely returns to a horizontal state, completing the whole set of coating operations; Finally, under the elastic action of the tension spring 984, the side foot plate 983 and the coating roller 985 are pulled back to their original positions, and the grabbing arm 2 grabs the coated mobile phone cover and returns it to the surface of the upper and lower material belts 3 to realize unloading.

[0039] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
