Description

[0002] Currently, mobile phone charger casings are fitted with a protective film at the factory. This film application is typically done manually using a film-applying mold. Considering the high labor costs, many manufacturers are developing film-applying mechanisms, such as the one described in application number CN202220884982.5, titled "A Film-Applying Machine." This machine uses a hot-melt sealing method, where the packaging film is wrapped around the product as it enters the film-applying area, and then cut using a heat-sealing die and cutter. This method leaves heat-sealing marks on the casing surface, which is unsightly and affects usability. Therefore, there is a need to develop a film-applying mechanism capable of applying a ring-shaped film to mobile phone charger casings. Summary of the Invention

[0041] The present invention will now be described in detail with reference to the accompanying drawings. Figures 1 to 11 As shown.

[0042] Example: See Figure 1 , Figure 2 A membrane covering mechanism, comprising:

[0043] Protective film supply mechanism 1, used to provide an annular protective film;

[0044] The protective film fixing mechanism 2 is provided with a front adsorption block 11, which is connected to an air extraction device (not shown in the figure, this is prior art). The upper surface of the front adsorption block 11 is provided with multiple adsorption holes.

[0045] The protective film adsorption mechanism 3 is connected to a transfer mechanism, which is used to transfer the protective film to the front adsorption block 11 and cooperate with the front adsorption block 11 to shape the protective film.

[0046] The linear conveyor mechanism 4 is used to push the object forward to the adsorption block 11 and attach it to the protective film.

[0047] When this technical solution is in operation: the protective film supply mechanism 1 delivers the annular protective film to the loading station; the transfer mechanism drives the protective film adsorption mechanism 3 to move above the loading station, the protective film adsorption mechanism 3 adsorbs the protective film, and then transfers it through the transfer mechanism, so that the protective film is located above the front adsorption block 11. Under the action of the air extraction device, the surface of the front adsorption block 11 is kept under negative pressure, the lower end face of the annular protective film is adsorbed on the front adsorption block 11, and at the same time the upper end face of the protective film is adsorbed by the protective film adsorption mechanism 3, and the protective film is shaped; finally, the linear conveying mechanism 4 moves to push the object that needs to be covered with the protective film, such as a shell, to the front adsorption block 11, and the object passes through the protective film and is covered with the protective film. The protective film supply mechanism 1 can be based on existing technology, such as application number CN202011285098.1, entitled: A film material conveying mechanism; the annular protective film is conveyed to the loading position through the feeding mechanism and the cutting mechanism 13; for example, the feeding mechanism conveys the protective film to the loading position, and then the cutting mechanism 13 operates to cut off the protective film at the front end to form an annular protective film.

[0048] See Figure 7 , Figure 8 Furthermore, it also includes: a membrane support mechanism, which includes a rear support platform assembly 5. The support platform assembly 5 includes a rear support bracket and a support platform connected to the rear support bracket. The support platform is located behind the front adsorption block 11, and a support module abuts against the top of the support platform. See [reference needed]. Figure 11 The front end of the support module is pointed, preferably tapered; the transfer mechanism is connected to a clamping component for holding the support module.

[0049] During operation, the protective film is fitted onto the object. When the object is inserted into the protective film, the opening diameter of the protective film needs to correspond to the size of the object. Since the protective film is flexible, it is difficult to keep it from wobbling on the left and right sides. To solve this problem, this technical solution sets up a film-supporting mechanism. The film-supporting block 8 is initially set on the support platform, and the support module is set opposite to the annular protective film shaped on the front adsorption block 11. When the linear conveying mechanism 4 conveys the object forward, the object will first abut against the support module, pushing the film-supporting block 8 forward. The film-supporting block 8 transitions from the support platform to the front adsorption block 11. Since the front end of the film-supporting block 8 is pointed, it can be designed as a cone. The front end smoothly inserts into the protective film and gradually enters the protective film. At the same time, the rear end of the film-supporting block 8 expands the protective film. Then, the object enters the protective film along the film-supporting block 8 and pushes the film-supporting block 8 out, and the object fits onto the protective film. In the specific design, the size of the rear end of the support module can be equal to or slightly larger than the size of the object, that is, the cross-section of the support module can cover the cross-section of the object. After the object is covered with film, it can be transferred by a robot or manually. At this time, the linear conveying mechanism 4 resets, the transfer mechanism drives the clamping assembly to move to the vicinity of the support module, and then the clamping assembly moves to clamp the support module. At the same time, the protective film adsorption mechanism 3 also comes to the protective film feeding position and adsorbs the annular protective film. Then, the transfer mechanism resets, the clamping assembly drives the film support block 8 to move to the support platform, and the protective film adsorption mechanism 3 transfers the new protective film to the front adsorption block 11.

[0050] Only then can Figure 5 , Figure 6 Furthermore, the transfer mechanism includes a base plate 62, which is provided with a transversely arranged transverse guide rail 63 and a transverse slider 67. The upper end of the transverse slider 67 is connected to a longitudinally arranged slide plate 64. Vertical plates 65 are respectively connected to both sides of the slide plate 64. The upper end of the vertical plate 65 extends backward to provide a receiving part 66. The vertical plate 65 or the slide plate 64 is connected to a transverse linear module 61. The receiving part 66 on one side is fixedly connected to the adsorption mechanism 3 on the protective film. The clamping assembly includes two pushing cylinders 10, which are respectively connected to the receiving parts 66 on both sides. The protective film supply mechanism 1 is located at the front end of the base plate 62.

[0051] In this technical solution, the transfer mechanism is connected to both the clamping assembly and the adsorption mechanism 3 on the protective film. The transverse linear module 61 of the transfer mechanism can be a transverse cylinder, and the push rod of the transverse cylinder is fixedly connected to one of the vertical plates 65. The transverse cylinder drives the vertical plate 65 to move laterally. With the cooperation of the transverse slider 67 and the transverse guide rail 63, the vertical plates 65 on both sides move smoothly. At the same time, it drives the clamping assembly and the adsorption mechanism 3 on the protective film to move together, resulting in a smooth operation that saves cost and time. When the clamping assembly moves forward, it is in the open clamping state. Secondly, by using clamps to drive the membrane support block 8 to move, the position of the membrane support block 8 can be adjusted. For example, the clamps on both sides can push and clamp the support module in sequence.

[0052] See Figure 1 , Figure 2 , Figure 7 , Figure 8 Furthermore, the rear support includes a lifting mechanism 51, which is connected to a bidirectional cylinder 52. Both push rods of the bidirectional cylinder 52 are connected to clamping arms 55, and the upper end of the clamping arms 55 is connected to a pad block 56. The upper end face of the bidirectional cylinder 52 is connected to a fixing plate 53, and the upper end of the fixing plate 53 is provided with a rear suction block 54, which is the support platform. The upper end face of the support platform abuts against a guide cylinder 6.

[0053] Preferably, the lifting mechanism 51 includes a base plate 511, a vertically arranged support plate 512 connected to the base plate 511, a vertical cylinder 515 connected to one side of the support plate 512, a vertical guide rail 516 and a vertical slider 514 slidably connected to the vertical guide rail 516 connected to the other side of the support plate 512, a vertical lifting plate 513 connected to the vertical slider 514, an intermediate block 517 connected to the upper end of the vertical lifting plate 513, the intermediate block 517 being fixedly connected to the push rod of the vertical cylinder 515; and a receiving block 518 connected to the middle of the vertical lifting plate 513.

[0054] The rear support is equipped with a lifting mechanism 51, which can adjust the height of the support platform so that the end face of the support platform is flush with the end face of the front adsorption block. The guide cylinder 6 is initially fixed to the rear adsorption block 54 after being adsorbed by the rear adsorption block 54, and then further fixed and positioned by the bidirectional cylinder 52 and the clamping arm 55. After the guide cylinder 6 is set, when the membrane support block 8 moves backward by the clamping assembly, the rear end of the membrane support block 8 is inserted into the front end of the guide cylinder 6, and then the clamping assembly is released. When the object is conveyed by the linear conveyor mechanism 4, it is first inserted into the rear end of the guide cylinder 6, then abuts against the membrane support block 8 and moves forward together. The guide cylinder 6 adjusts the consistency between the object and the support module to avoid misalignment between the object and the membrane support block 8, which would lead to failure of the membrane covering. Preferably, the rear end opening of the guide cylinder 6 is trumpet-shaped and the front end is cylindrical to facilitate the insertion of the object. The object can be a charger shell, etc. The upper end face of the rear adsorption block 54 is provided with an adsorption hole, and the side is connected to an air extraction hole and connected to an air extraction device through the air extraction hole. This is existing technology and will not be described in detail.

[0055] See Figure 9 , Figure 10 Furthermore, the protective film fixing mechanism 2 includes a front bracket, which is equipped with a lifting mechanism 51, and the lifting mechanism 51 is connected to the front adsorption block 11.

[0056] The lifting mechanism can adopt the same structure as the rear bracket. The lifting mechanism 51 drives the front adsorption block 11 to rise and fall, and adjusts the height of the front adsorption block 11 at the same time.

[0057] See Figure 1 , Figure 2 , Figure 5 , Figure 6 Furthermore, the protective film supply mechanism 1 includes a frame 11, which is provided with a protective film unwinding mechanism 12 and a cutting mechanism 13; a protective film temporary storage frame 14 and an object temporary storage box 15 are connected in sequence to the front side of the frame 11; one of the vertical plates 65 of the transfer mechanism is connected to a suction cup assembly 9 for adsorbing objects.

[0058] Both the protective film unwinding mechanism 12 and the cutting mechanism 13 can adopt existing technologies, which will not be described in detail here. The protective film enters the protective film temporary storage frame 14 through the protective film unwinding mechanism 12, and is then cut by the cutting mechanism 13. At this time, the protective film temporary storage frame 14 is the protective film loading position, and the transfer mechanism drives the suction mechanism 3 on the protective film to pick up the material here. Secondly, in order to facilitate the removal of the object covered with the protective film, this technical solution also provides a suction cup assembly 9. When the object is covered with the protective film, the driving vertical plate 65 of the transfer mechanism moves backward, so that the suction cup assembly 9 is above the object and adsorbs it; then, when the transfer mechanism moves forward, it simultaneously drives the suction cup assembly 9 to move, and the suction cup assembly 9 adsorbs the object and brings it to the object temporary storage box 15.

[0059] See Figures 1 to 6 Furthermore, the protective film adsorption mechanism 3 includes an adsorption lifting mechanism 31 connected to the vertical plate 65, and a horizontal telescopic mechanism 32 at the upper end of the adsorption lifting mechanism 31, which is connected to an upper adsorption block 34.

[0060] The protective film adsorption mechanism 3 needs to pick up the protective film and also assist in shaping it; a lifting mechanism and a horizontal telescopic mechanism 32 are set to assist in adjusting the position of the upper adsorption block 34 so that the upper adsorption block 34 can work better. At this time, the upper adsorption block 34 can be a plastic block with adsorption or adhesive force.

[0061] Preferably, the adsorption lifting mechanism 31 includes an adsorption vertical cylinder 515, the upper end of which is connected to a horizontal support plate. The horizontal telescopic mechanism 32 includes an adsorption longitudinal cylinder connected to the horizontal support plate, and the push rod of the adsorption longitudinal cylinder is fixedly connected to the front adsorption block 11.

[0062] Preferably, the outer side of the vertical adsorption cylinder 515 is connected to a vertical guide rail 516 and a vertical slider 514. The vertical slider 514 is connected to a vertical base plate, and the vertical base plate is fixedly connected to a horizontal support plate 512. The upper end of the vertical adsorption cylinder is connected to a horizontal slider, and the horizontal slider is connected to a bearing plate 33. The bearing plate 33 is connected to the front adsorption fixing block.

[0063] In this technical solution, the vertical adsorption cylinder 515 and the longitudinal adsorption cylinder are used as the main body of the lifting mechanism and the horizontal telescopic mechanism 32, which is simple in structure and easy to implement. Secondly, in order to keep the whole stable during adjustment, components such as the vertical slider 514 and the horizontal slider are set to assist its smooth movement.

[0064] See Figure 5 Furthermore, the suction cup assembly 9 is connected to the vertical plate 65 via a lifting cylinder 93; the upper end of the push rod of the lifting cylinder 93 is connected to a connecting plate 94, and the adsorption assembly includes an adsorption seat 92 and a suction cup 91 connected to the adsorption seat 92, with the adsorption seat 92 fixed to one end of the connecting plate 94.

[0065] Since the adsorption assembly is only used to transfer objects covered with protective films, only a lifting cylinder 93 connected to it is provided; the lifting cylinder 93 drives the suction cup assembly 9 to adjust the height, which facilitates the adsorption and release of objects. In use, the adsorption seat 92 is connected to the air extraction device, and the objects are adsorbed by the suction cup 91.

[0066] See Figure 1 , Figure 2 Furthermore, the film-covering mechanism also includes an auxiliary positioning mechanism 7. The auxiliary positioning structure includes an auxiliary support 72, which is connected to an auxiliary lifting mechanism 71. The auxiliary lifting mechanism 71 is connected to an auxiliary positioning plate 73. The upper end of the auxiliary positioning plate 73 is connected to a lower bidirectional cylinder 74. The upper end of the lower bidirectional cylinder 74 is connected to an upper bidirectional cylinder 75. The push rods of the two layers of the lower bidirectional cylinder 74 are connected to a support arm 76. The push rod of the upper bidirectional cylinder 75 is connected to an adjusting clamping arm 77. The upper end of the upper bidirectional cylinder 75 is connected to a bearing block.

[0067] The auxiliary positioning mechanism 7 is used to position the object. In practical applications, the object is transferred to the auxiliary positioning mechanism 7 by other conveying devices, such as a robotic arm. The auxiliary positioning mechanism 7 is located behind the protective film fixing mechanism 2. When the object is transferred to the carrier block, the upper bidirectional cylinder 75 is activated, and the two adjusting clamping arms 77 clamp the object and adjust its position. Then, the linear conveying mechanism 4 is activated to clamp the object first and then push the object forward to enter the protective film fixing mechanism 2 for film application.

[0068] Furthermore, the linear conveying mechanism 4 includes a multi-stage cylinder assembly 41 and a clamp 42. The multi-stage cylinder assembly 41 drives the clamp 42 to move, and the clamp 42 is used to hold objects.

[0069] Of course, the linear conveyor mechanism 4 can also use a single-stage long cylinder; multi-stage cylinders can be used with cylinders of different precision; when controlling the movement of the fixture, the cylinder with low precision and long stroke is used first, and when applying the film, the cylinder with high precision and short stroke is used. This can improve efficiency and avoid vibration caused by high speed during film application, which would affect the success rate of film application. The fixture clamps the rear end of the corresponding object; this is existing technology and will not be described in detail.

[0070] The above description is only a preferred embodiment of the present invention. For those skilled in the art, there will be changes in the specific implementation and application scope based on the ideas of the present invention. The content of this specification should not be construed as a limitation of the present invention.
