[0027] In order to more clearly understand the technical means of the present invention and implement it according to the contents of the specification, the specific implementation methods of the present invention are further described in detail below in conjunction with the drawings and examples. The following examples are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0028] like Figures 1 to 4 As shown, the present invention discloses an automatic film wrapping device, which can be used to attach protective films to products such as mobile phones, tablets, etc., and the protective film serves as a protection for the products during transportation. The device includes a frame 1, a film pasting platform 2 arranged on the frame 1, a lifting component 3 and a clamping component 4 arranged below the film pasting platform 2, and a pre-pressing component 5 and a flipping component 6 arranged on the side of the film pasting platform 2.

[0029] A plurality of vacuum adsorption holes are provided on the upper surface of the film pasting platform 2, and the vacuum adsorption holes are connected to the negative pressure device. When the protective film is placed on the film pasting platform 2, the negative pressure device is started to adsorb the protective film on the film pasting platform 2 through the vacuum adsorption holes to prevent the protective film from being displaced and ensure the quality of the film pasting.

[0030] Furthermore, the film-sticking platform 2 is also provided with a positioning groove for positioning and placing the product, and the positioning groove is defined by limiting blocks arranged at the four corners of the film-sticking platform 2, and the inner side walls relative to each limiting block are respectively in contact with the corresponding angular outer side walls of the product.

[0031] like Figure 5The lifting assembly 3 includes a lifting drive 31 and a rolling member 32 that rises and falls with the lifting drive 31. The clamping assembly 4 is arranged at the lifting output end of the lifting assembly 3, including a clamping member 41 and a clamping drive 42 that drives the clamping member 41 to clamp the product; the clamping drive 42 is fixedly arranged on the output end of the lifting drive 31, and the clamping drive 42 has two output ends extending along the width direction of the product, and the two output ends are respectively connected to the two groups of clamping members 41 through two groups of clamping arms 43. The clamping drive 42 can be two independent clamping cylinders or a double-stroke cylinder.

[0032] The film-sticking platform 2 is provided with lifting channels on both sides, and the rolling member 32 and the clamping member 41 move up and down along the lifting channels under the drive of the lifting driving member 31. The clamping member 41 and the rolling member 32 are arranged up and down, and the clamping member 41 includes a bearing platform 411 and an arc surface 412 respectively located on both sides. The bearing platforms 411 on both sides are used to support both sides of the protective film before the protective film is attached, and the arc surface 412 matches the outer side wall of the product. The arc surface 412 is lifted to the corresponding height of the side of the product under the drive of the lifting driving member 31, and then driven by the clamping driving member 42, when the two groups of arc surfaces 412 move relatively and abut against the two side walls of the product to form a clamping state, the arc surface 412 covers the upper end surface of the product along the side wall of the product; so that the two groups of arc surfaces 412 can better press and attach the protective film to the upper end surface of the product.

[0033] During operation, the protective film is attached to the film sticking platform 2, and the carrying platform 411 cooperates with the film sticking platform 2 to support the protective film. The product is placed horizontally on the protective film on the film sticking platform 2, and the jacking drive 31 is started. The jacking drive 31 drives the rolling part 32 to move upward and push up the protective films on both sides of the film sticking platform 2, so that the protective films on both sides of the product are folded upward. Under the continuous push of the jacking drive 31, the rolling part 32 rolls the protective film and sticks it to both sides of the product. At this time, the clamping drive 42 is started, and the clamping parts 41 on both sides move relatively, and the arc surface 412 abuts and fits against the outer wall of the product to clamp the product, and the protective film is crimped and attached to the upper end surface of the product through the arc surface 412, so that the protective film on the upper end surface can better cover the protective films on the two side walls in the subsequent rolling and sticking process.

[0034] Specifically, the rolling member 32 includes a clamping roller 321 , and the clamping roller 321 is connected to the output end of the jacking driving member 31 through a jacking arm 33 .

[0035] Furthermore, the clamping roller 321 is connected to the lifting arm 33 through a swing rod mechanism. Specifically, the swing rod mechanism includes swing rods connected to both ends of the clamping roller 321, and a hinge shaft penetrating the middle of the two sets of swing rods and hingedly connected to the lifting arm 33. The other ends of the two sets of swing rods are connected through a spring seat, and the spring seat is connected to the lifting arm 33 through an elastic member 34, and cooperates with the travel limit groove on the swing rod. Under the elastic reset action of the elastic member 34, the clamping roller 321 is kept in contact with the two side walls of the product. Through the swing rod mechanism structure, the reliability of the clamping roller 321 contacting the two side walls of the product is improved.

[0036] The flip assembly 6 is arranged on one side of the product, including an adsorption plate 61 located at one end of the product and a flip driving member 62 that drives the adsorption plate 61 to flip along a flip center. The adsorption plate 61 is connected to the output end of the flip driving member 62. A cavity is arranged inside the adsorption plate 61, and the cavity is connected to an external device through a venting joint. The venting joint includes a vacuum joint and a vacuum breaking joint. The cavity is evacuated through the vacuum joint to form a vacuum or ventilated through the vacuum breaking joint to break the vacuum. The adsorption plate 61 has a vacuum adsorption hole, and a groove 611 is arranged on the surface of the adsorption plate 61. When the protective film is attached to the film attaching platform 2, the protective film on the upper end surface of the product is adsorbed in the groove 611.

[0037] Furthermore, the groove 611 is defined by the adsorption plate 61 and the mounting plates on both sides of the adsorption plate 61. The mounting plates on both sides have travel grooves. By adjusting the fasteners at different positions of the travel grooves, the groove 611 can be adjusted to different lengths, widths and shapes.

[0038] The adsorption plate 61 is provided with a film sticking roller 63 at one end close to the flipping center, and the film sticking roller 63 is rotatably connected to the adsorption plate 61. Driven by the flipping driving member 62, the adsorption plate 61 flips to various angles through the rotation center. When the adsorption plate 61 flips to the film sticking angle, the adsorption plate 61 moves along the length direction of the product and drives the film sticking roller 63 to roll and stick the protective film along one end of the product to the other end. The flipping driving member 62 is a flipping motor, and the adsorption plate 61 is connected to the output shaft of the flipping motor through a reducer.

[0039] Furthermore, the film-laminating roller 63 and the adsorption plate 61 are connected by the above-mentioned rocker mechanism, the hinge axis of the rocker mechanism is passed through the middle of the two groups of rockers and is hingedly connected to the adsorption plate 61, the spring seat is connected to the adsorption plate 61 by the elastic member 34, and cooperates with the travel limit groove on the rocker, under the elastic reset action of the elastic member 34, the film-laminating roller 63 is kept in contact with the upper end surface of the product and pressed against each other, so as to improve the reliability of the contact between the film-laminating roller 63 and the upper end surface of the product.

[0040] In the following description, the length direction of the product is the X direction, the direction on the horizontal plane perpendicular to the X direction is the Y direction, and the direction perpendicular to the horizontal plane is the Z direction. The above directions are only used to illustrate the setting directions of relevant components or parts in this device and are not used to limit the directions.

[0041] An X-axis linear module 7 with a travel along the X direction is provided on one side of the product, and the flip motor is fixedly arranged at the output end of the X-axis linear module 7. Under the drive of the X-axis linear module 7, the adsorption plate 61 and the film-sticking roller 63 are driven to move along the X direction and roll the film. In this embodiment, the drive of the X-axis linear module 7 can be a linear motor, and the connection between the linear motor and the flip assembly 6 can adopt a screw structure commonly used in the art.

[0042] In order to prevent the protective film from being deformed and torn during the rolling and laminating process, which affects the laminating accuracy of the protective film, especially the protective film has a narrower section along the laminating direction, which is relatively fragile due to its small area and is more likely to be deformed and torn during the rolling and laminating process. In this embodiment, a pre-pressing component 5 is provided above the head end of the laminating platform 2, and the pre-pressing component 5 includes a pre-pressing roller 51 that can move along the Y and Z directions; first, after the adsorption plate 61 is flipped to the pre-pressing angle, the pre-pressing roller 51 moves to the head end of the product, and rolls and attaches the protective film to the head end of the product to complete the pre-pressing of the protective film at the head end of the product, prevent the protective film from being deformed and torn during the subsequent rolling and laminating process, and also play a positioning role for the protective film.

[0043] Specifically, Figure 6 As shown, the pre-pressing assembly 5 also includes a Y-axis linear module 52 with an output end stroke along the Y direction and a Z-axis linear module 53 with an output end stroke along the Z direction, and the pre-pressing roller 51 is hingedly connected to the output end of the Z-axis linear module 53.

[0044] After the pre-pressing of the protective film is completed, the flipping motor flips the adsorption plate 61 to the film sticking angle, and the film sticking roller 63 completes the rolling film sticking on the upper end surface of the product. Finally, the flipping motor flips the adsorption plate 61 to the film pressing angle, and the film sticking roller 63 continues to roll the protective film to the end of the product. At this time, the protective film is folded downward, and the film sealing assembly 8 arranged at the end finally seals the protective film.

[0045] Specifically, Figure 7The film sealing assembly 8 includes a film sealing roller 81 and a film sealing driving member 82 for driving the film sealing roller 81 to move relative to the product. The film sealing driving member 82 includes two sets of slide cylinders with different strokes. The large-stroke slide cylinder is fixedly arranged on the frame 1, and the small-stroke slide cylinder is arranged at the output end of the large-stroke slide cylinder. The film sealing roller 81 is connected to the output end of the small-stroke slide cylinder through a hinge. Under the driving action of the large-stroke slide cylinder, the film sealing roller 81 moves to the end of the product, and the small-stroke slide cylinder drives to roll the downward folded protective film to the lower end surface of the product and complete the protective film sealing. In order to ensure the firmness of the film sealing, the film sealing roller 81 rolls the protective film back and forth multiple times through the pneumatic stroke of the small-stroke slide cylinder, and the two sets of slide cylinders are combined to shorten the stroke time.

[0046] The pre-pressing roller 51 and the film sealing roller 81 are both connected to corresponding structures through the above-mentioned rocker mechanism, which will not be described in detail here.

[0047] The film sticking platform 2 is fixed on the support platform 11 of the frame 1 . A through slot 12 is provided in the middle of the support platform 11 . The lifting channel and the operating spaces at both ends of the product are connected to the through slot 12 .

[0048] It can be seen from this embodiment that the device can not only attach the protective film along the side wall direction of the product, but also attach the protective film along the end direction of the product.

[0049] The film sticking angle, pre-pressing angle and film pressing angle of the adsorption plate 61 are all determined by setting.

[0050] In addition, the protective film used in this embodiment is as follows Figure 8 As shown, it includes A film 01 for attaching to the lower end surface and two side walls of the product, B film 02 for attaching to the upper end surface of the product, and C film 03 and D film 04 for attaching to the two ends of the product, wherein C film 03 is the connecting section of A film 01 and B film 02, and C film 03 has a notch 031, which is a narrow section of the protective film, and D film 04 is connected to the free end of B film 02. When attaching the film, place the product on A film 01, then fold the two sides of A film 01 upwards, attach C film 03 to the end, attach B film 02 to the upper end surface, and then press the end of D film 04 to A film 01 along the end, and press the entire protective film together to complete the attachment of the entire protective film.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the technical principles of the present invention, and these improvements and modifications should also be regarded as within the scope of protection of the present invention.
