[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0035] Please see Figure 1-12 In this embodiment of the present invention, an automatic punching, film-applying, and packaging equipment for injection molding includes a workbench 1 and a work frame 2 disposed on one side of the workbench 1. The workbench 1 is provided with a feeding conveying mechanism for feeding and conveying shell materials. A first shell material clamping and conveying mechanism is disposed on one side of the feeding conveying mechanism to clamp the transported shell materials. A shell material film-applying mechanism and a shell material punching mechanism are also disposed on one side of the feeding conveying mechanism. A shell material wrapping mechanism is disposed on one side of the shell material punching mechanism to wrap and apply film to the punched shell materials. A second shell material clamping and conveying mechanism is disposed on one side of the shell material wrapping mechanism to clamp and convey the shell materials internally for wrapping and applying film. A third shell material clamping and conveying mechanism is disposed on one side of the second shell material clamping and conveying mechanism to cooperate in clamping and conveying the shell materials. The mechanism includes a material plate (not shown in the figure) below the third shell material clamping and conveying mechanism for centralized storage of the shell materials it clamps and conveys. The material plate is horizontally mounted on the work frame 2. The top of the work frame 2 is equipped with a four-sided pressing mechanism for clamping, adsorbing and conveying the material plate and the shell materials placed on it. A carton positioning mechanism is provided on one side of the bottom of the work frame 2. A carton 54 is placed on the carton positioning mechanism for storing the material plate that carries the shell materials. A sponge pulling and cutting mechanism for placing sponge pads into the carton 54 is provided above the carton positioning mechanism. The material plate and the shell materials carried by the material plate can be transported into the carton 54 through the four-sided pressing mechanism. When the material plate and shell materials are placed into the carton 54 in batches, the sponge cut by the sponge pulling and cutting mechanism can be used as a separator.
[0036] Based on the cooperation between the above-mentioned institutions, the following working principle can be derived:
[0037] Since the shell material is used in Bluetooth headsets, it is divided into an upper shell material and a lower shell material. The upper and lower shell materials are transported in batches to the shell material laminating mechanism and the shell material punching mechanism via a feeding conveyor. The first shell material clamping and transporting mechanism clamps and transports the upper shell material into the shell material laminating mechanism for lamination. After lamination, the upper shell material is pushed out from inside the laminating mechanism and slides off the worktable 1. The lower shell material is transported to the shell material punching mechanism via a second shell material clamping and transporting mechanism for punching. After punching, the second shell material clamping and transporting mechanism clamps and transports the punched lower shell material to the shell material wrapping mechanism. The internal mechanism performs wrapping and film application. The wrapped and film-applied lower shell material is then clamped and transported by the third shell material clamping and transporting mechanism to the material board on the work frame 2 for centralized placement. Once the material board is full of wrapped and film-applied lower shells, the four-sided pressing mechanism clamps and absorbs the material board and transports it to the inside of the carton 54 placed above the carton positioning mechanism. When the material board is placed inside the carton 54, the sponge is cut into sponge pads by the sponge pulling and cutting mechanism. The sponge pads fall into the inside of the carton and are laid flat on the material board so that the lower shell material at the bottom will not be pressed when the next batch of material boards is stacked. Finally, the lower shell material can be packaged in the carton 54.
[0038] The feeding and conveying mechanism includes a conveyor belt 3 mounted on a workbench 1. A material channel baffle 13 for segmented transport of shell materials is mounted across one side of the conveyor belt 3. A shell material positioning baffle 14 for positioning and blocking the segmented transport of shell materials is located at the end of the conveyor belt surface, allowing the subsequent first and second shell material clamping and transporting mechanisms to clamp and transport the positioned shell materials. The feeding and conveying mechanism also includes a shell material clamping and adjusting mechanism for directional adjustment of the shell materials transported above it. This shell material clamping and adjusting mechanism includes a crossbeam. The system includes a second fixed frame 8 on the conveyor belt 3 and a first sensor 12 near the second fixed frame 8 that senses the shell material being conveyed above the conveyor belt 3. The second fixed frame 8 is equipped with a first cylinder 9 that moves horizontally at its top, and a second cylinder 10 that extends vertically below the first cylinder 9. A second cylinder gripper 11, which moves synchronously with the second cylinder 10 and clamps and rotates the shell material being conveyed above the conveyor belt 3, is located on one side of the second cylinder 10. This allows the shell material to be conveyed through the conveyor belt 3 and discharged from the first sensor 12. As the shell material passes by, the first sensor 12 senses it. When the direction of the detected shell material is inconsistent with that of the other shell materials, the first sensor 12 sends a signal to the conveyor belt 3, the first cylinder 9, the second cylinder 10, and the second cylinder gripper 11. At this time, the conveyor belt 3 stops running, and the first cylinder 9, along with the second cylinder 10 and the second cylinder gripper 11, moves to above the shell material whose direction needs to be adjusted. The second cylinder 10 then moves the second cylinder gripper 11 downwards until the second cylinder gripper 11 clamps the shell material. After that, the second cylinder 10... The second cylinder gripper 11 is driven to rise, separating the shell material from the conveyor belt 3. During the rising process, the second cylinder gripper 11 rotates to adjust the orientation of the gripped shell material. After the orientation adjustment, the shell material is lowered by the second cylinder gripper 11 along with the second cylinder 10 until the shell material is completely flat on the conveyor belt 3. At this time, the second cylinder gripper 11 releases the shell material, and at the same time, the first cylinder 9, the second cylinder 10, and the second cylinder gripper 11 reset, and the conveyor belt 3 continues to run, thereby causing the shell material to flow in a uniform direction to the material channel baffle 13 at its rear end.
[0039] The first shell material clamping and conveying mechanism includes a fifth fixed frame (not shown in the figure) disposed on one side of the feeding conveying mechanism and vertically fixed on the workbench 1. The fifth fixed frame is provided with a sixteenth cylinder (not shown in the figure) that moves horizontally at its top end. The sixteenth cylinder is provided with a sixth cylinder gripper (not shown in the figure) that moves vertically at its bottom end. The sixth cylinder gripper is parallel to the conveyor belt 3. When the shell material transported on the conveyor belt 3 is blocked and limited by the material channel baffle 13, the sixteenth cylinder and the sixth cylinder gripper move to the conveyor belt 3 and clamp the shell material at the material channel baffle 13 to the shell material film-coating mechanism for shell material film coating.
[0040] The shell material coating mechanism includes a first support platform 22 disposed on one side of the feeding conveyor and fixed on the workbench 1, a film roll support frame 27 disposed on one side of the first support platform 22, and a film roll 28 wrapped with packaging film disposed on the film roll support frame 27. The first support platform 22 is provided with a fourth moving frame 23 that moves horizontally above it, and the fourth moving frame 23 is provided with a shell material placement platform 24 that moves synchronously with it and is used to place the shell material to be coated. At the two ends of the other side above the first support platform 22, there are respectively a third cylinder gripper 26 for pulling the packaging film wrapped on the film roll 28 and a fourth cylinder gripper 31 for clamping and limiting the pulled packaging film. The third cylinder gripper 26 is provided with a fifth cylinder 29 for moving it above the first support platform 22.
[0041] The shell film application mechanism also includes a third fixed frame 15 disposed on one side of the film roll support frame 27, and the third fixed frame 15 is provided with a third movable frame 16 that moves horizontally at its top, and the third movable frame 16 is provided with a movable platform 17 that moves up and down on one side of it, and the movable platform 17 is provided with a first film cutter 18 and a film pressing block 19 that move synchronously with it and are located on both sides below it.
[0042] Then, when the shell material is clamped and placed on the shell material placement platform 24 by the first shell material clamping and conveying mechanism, the film roll 28 unwinds the wrapped packaging film, so that one end of the packaging film passes through the middle of the fourth cylinder gripper 31. At this time, the fifth cylinder 29 drives the third cylinder gripper 26 to move to one side of the fourth cylinder gripper 31 and clamp the packaging film that has passed through the fourth cylinder gripper 31. Then, the fifth cylinder 29 resets it and pulls the packaging film. After the third cylinder gripper 26 is reset, the fourth cylinder gripper 31 will continue to clamp and limit the packaging film that has passed through the middle, so that the packaging film is horizontally mounted on the first support platform 22. At this time, the fourth moving frame 23, along with The shell material placement platform 24, on which the shell material is placed, moves to below the packing film. At this time, the third moving frame 16, together with the moving platform 17, moves to above the packing film. The moving platform 17, together with the first film cutter 18 and the film pressing block 19, moves downward, causing the first film cutter 18 to cut the packing film. The cut packing film is pressed onto the shell material by the film pressing block 19. When the film pressing block 19 presses the packing film onto the shell material, it also clamps the shell material. At this time, the moving platform 17 rises and resets, causing the shell material with the film to rise. Then, the third moving frame 16 transports the shell material with the film held by the moving platform 17 out of the shell material film application mechanism for subsequent rounds of shell material film application.
[0043] A fourth cylinder 21 is provided between the third movable frame 16 and the third fixed frame 15, and the fourth cylinder 21 is located on one side of the third fixed frame 15. The fourth cylinder 21 is driven to move the third movable frame 16 and the movable platform 17. A third cylinder 20 is provided between the movable platform 17 and the third movable frame 16, and the third cylinder 20 is located on the third movable frame 16. The third cylinder 20 is driven to move the movable platform 17 up and down on the third movable frame 16.
[0044] The shell punching mechanism includes a third support platform 40 located on one side of the feeding conveyor mechanism and on the worktable 1. A second shell placement fixture 43 is mounted on the third support platform 40 for placing the shell material. Ninth cylinders 44 are mounted on both sides of the third support platform 40, and one end of each ninth cylinder 44 drives a punch 45 to clamp the shell material placed on the second shell placement fixture 43. An eighth cylinder 41 is located at the bottom of the third support platform 40, and the eighth cylinder 41 drives a pin 42 that penetrates the second shell placement fixture 43. The second shell placement fixture 43 is connected to a waste discharge pipe 46. Therefore, when… When the second shell material clamping and transporting mechanism clamps and transports the shell material transported on the feeding conveyor to the second shell material placement fixture 43, the ninth cylinder 44 drives the punch 45 to approach the side of the second shell material placement fixture 43 until the punch 45 clamps the shell material on the second shell material placement fixture 43. At this time, the eighth cylinder 41 drives the ejector pin 42 to move upward and penetrate the second shell material placement fixture 43, thereby penetrating the shell material on the second shell material placement fixture 43, thus realizing the punching of the shell material. After the shell material is punched, each component is reset. The waste material generated by punching will fall into the waste discharge pipe 46 at the same time as the components are reset, and then be discharged through the waste discharge pipe 46.
[0045] The second shell material clamping and transporting mechanism includes a first fixed frame 6 disposed on one side of the feeding conveying mechanism and vertically located on the worktable 1. The first fixed frame 6 is provided with a first cylinder gripper 7 that moves horizontally at its top and clamps the shell material. By moving the first cylinder gripper 7 on the first fixed frame 6, the shell material conveyed on the feeding conveying mechanism can be clamped and transported to the shell material punching mechanism for punching. The punched shell material is also clamped and transported by the mechanism to the shell material wrapping mechanism for wrapping and film application.
[0046] The shell wrapping mechanism includes a second support platform 32 disposed on one side of the shell punching mechanism and fixed on the worktable 1. The second support platform 32 is provided with a turntable 35 that rotates on both sides of its surface. The turntable 35 is provided with a first shell placement fixture 36 that moves synchronously with it and places the punched shell. A film traction column 33 that pulls the packaging film is provided on the side away from the turntable 35. A film cutter moving frame (not shown in the figure) is provided on one side of the second support platform 32. The film cutter moving frame is provided with a second film cutter 39 that cuts the film on both sides inside. The second support platform 32 is provided with a seventeenth cylinder (not shown in the figure) that drives the film cutter moving frame to move horizontally at its top. Thus, when the film cutter moving frame moves from the outside of the second support platform 32 to the top of the second support platform 32, the second film cutter 39 can pass through the first shell placement fixture 36 together.
[0047] Then, when the punched shell material is clamped and transported to the first shell material placement fixture 36 by the second shell material clamping and transporting mechanism, the packaging film is pulled to the side of the first shell material placement fixture 36 by the film material traction column 33 and attached to the outer periphery of the shell material. At this time, the turntable 35 rotates together with the second shell material placement fixture 36, so that the packaging film attached to the outer periphery of the shell material is wrapped around the outer periphery of the shell material. After the turntable 35 rotates to a specified number of revolutions, the seventeenth cylinder drives the film cutter moving frame to move from the outside of the second support platform 32 to the top of the second support platform 32, so that the second film cutter 39 passes through the first shell material placement fixture 36 and cuts the packaging film, so that the packaging film can be wrapped around the outer periphery of the shell material. At this time, the seventeenth cylinder drives the film cutter moving frame to reset, and then the shell material wrapped with film is clamped and transported to the work frame 2 by the third shell material clamping and transporting mechanism.
[0048] A first motor 34 is provided between the turntable 35 and the second support platform 32, and the first motor 34 is located at the bottom of the second support platform 32. The first motor 34 is connected to the turntable 35 for driving, thereby driving the turntable 35 to rotate on the second support platform 32. A second sensor 38 and a sensing plate 37 are also provided between the turntable 35 and the second support platform 32. The sensing plate 37 is vertically located on the side of the turntable 35 and moves in the same direction as the turntable 35. The second sensor 38 is located on the side away from the turntable 35 and is provided on the second support platform 32. Thus, the rotation of the turntable 35 can drive the sensing plate 37 to pass through the inside of the second sensor 38, so that the second sensor 38 can sense the passing sensing plate 37 and calculate the number of rotations of the turntable 35.
[0049] The third shell material clamping and transporting mechanism includes a second connecting frame 62 disposed on one side of the shell material wrapping mechanism and fixed to the inner side of the work frame 2. The second connecting frame 62 is provided with a fifth moving frame 63 that moves horizontally on one side. The fifth moving frame 63 is disposed on a fifteenth cylinder 64 that moves synchronously thereto. The fifteenth cylinder 64 drives and connects to a sixth moving frame 65. The sixth moving frame 65 is vertically located on the side of the fifth moving frame 63. The sixth moving frame 65 is provided with a fifth cylinder gripper 66 that moves synchronously thereto. Thus, the shell material after wrapping and coating can be clamped and transported sequentially to the material plate of the work frame 1 through the fifth cylinder gripper 66.
[0050] The four-sided pressing mechanism includes a first movable frame 4 movably disposed inside the working frame 2 and a second movable frame 5 movably disposed on one side of the first movable frame 4. A first connecting frame 47, which moves synchronously with the bottom of the second movable frame 5, is provided at the bottom of the first connecting frame 47. A tenth cylinder 48 is provided at the bottom of the first connecting frame 47, and the tenth cylinder 48 drives a first pressure plate 49. An eleventh cylinder 50 is vertically disposed at each of the four corners of the surface of the first pressure plate 49, and a suction cup 51 for adsorbing the material plate is driven at the bottom of the eleventh cylinder 50. The first pressure plate 49 also has a twelfth cylinder 52 distributed on its side, and one side of the twelfth cylinder 52 drives... A second pressure plate 53 is provided, and the second pressure plate 53 is vertically located on the side of the first pressure plate 49. When the coated shell material is stacked on top of the material plate, the first moving frame 4 will move the second moving frame 5 to the top of the material plate. At this time, the second moving frame 5 drives the first connecting frame 47 and the first pressure plate 49 to press on the shell material. Then, the eleventh cylinder 50 at the four corners of the first pressure plate 49 drives the suction cup 51 to move downward and adsorb the four corners of the material plate. At the same time, the twelfth cylinder 52 drives the second pressure plate 53 to close to the side of the material plate, thereby clamping and transporting the material plate and shell material from the work frame 2 and transporting them into the carton 54 for packaging.
[0051] The carton positioning mechanism includes a carton clamping frame 56 located at the bottom of the work frame 2 and a thirteenth cylinder 55 that drives the carton clamping frame 56 to open and close. The carton 54 is placed between the carton clamping frames 56. The carton positioning mechanism also includes a fourth fixing frame 57 located at both the left and right ends of one side of the carton clamping frame 56. A second motor 58 is located on one side of the top of the fourth fixing frame 57. The second motor 58 drives a rotating shaft 59 that rotates on one side of the top of the carton 54. A third pressure plate 60 that rotates synchronously with the rotating shaft 59 is obliquely located on one side of the rotating shaft 59. The third pressure plate 60 is located on one side of the top of the carton 54. The second motor 58 drives the third pressure plate 60 to swing towards the top of the carton 54, thereby folding the carton 54 towards its top and packing the material board and shell material inside the carton 54.
[0052] The sponge cutting mechanism includes a sponge roll 67 rolled inside the work frame 2 and wound with sponge, a seventh movable frame 68 horizontally mounted above the carton positioning mechanism, a sponge cutter (not shown in the figure) for cutting the sponge on the side away from the seventh movable frame 68, and a guide roller 70 located above the sponge roll 67. At both ends of one side of the seventh movable frame 68, there are sixth cylinder grippers 69 that move synchronously with it. When the sponge roll 67 unwinds the sponge and the unwinding sponge is guided by the guide roller 70, the seventh movable frame 68 drives the sixth cylinder grippers 69 to clamp the guided sponge and simultaneously reset it, so that the sponge is horizontally mounted above the carton 54. At this time, the sponge cutter is driven to cut the sponge, thereby forming a sponge pad. The sponge pad falls into the carton 54 so that it will not press down on the bottom shell material when the next batch of material boards is stacked.
