[0025] 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.

[0026] like Figures 1 to 3 As shown, the utility model discloses an automatic film wrapping device, which can be used to attach protective film 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-applying platform 2 arranged on the frame 1, a lifting component 3 and a clamping component 4 arranged below the film-applying platform 2, and a pre-pressing component 5 and a flipping component 6 arranged on the side of the film-applying platform 2.

[0027] The upper surface of the film-sticking platform 2 is provided with a plurality of vacuum adsorption holes, which are connected to the negative pressure device. When the protective film is placed on the film-sticking platform 2, the negative pressure device is started to adsorb the protective film on the film-sticking platform 2 through the vacuum adsorption holes to prevent the protective film from being displaced and ensure the quality of the film-sticking.

[0028] Furthermore, the film-sticking platform 2 is also provided with a positioning groove for positioning and placing the product. The positioning groove is defined by limiting blocks 21 provided at the four corners of the film-sticking platform 2. The inner side walls relative to each limiting block 21 are respectively in contact with the corresponding outer side walls of the product.

[0029] like Figures 4 to 6The lifting assembly 3 includes a lifting drive 31 and a rolling element 32 that rises and falls with the lifting drive 31. The clamping assembly 4 is disposed at the lifting output end of the lifting assembly 3 and includes a clamping member 41 and a clamping drive 42 that drives the clamping member 41 to clamp the product. The clamping drive 42 is fixed to the output end of the lifting drive 31 and has two output ends extending along the width of the product. The two output ends are respectively connected to the two sets of clamping members 41 via two sets of clamping arms 43. The clamping drive 42 can be two independent clamping cylinders or a two-stroke cylinder.

[0030] The film-applying 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 drive member 31. The clamping member 41 and the rolling member 32 are arranged one above the other, and the clamping member 41 includes a bearing platform 411 and an arcuate surface 412 located on both sides, respectively. The bearing platforms 411 on both sides are used to support both sides of the protective film before the protective film is attached. The arcuate surface 412 matches the outer wall of the product. The arcuate surface 412 is lifted to the clamping height under the drive of the lifting drive member 31. Then, driven by the clamping drive member 42, when the two sets of arcuate surfaces 412 move relative to each other and abut against the two side walls of the product to form a clamping state, the arcuate surface 412 wraps along the side wall of the product to the upper end surface of the product; so that the two sets of arcuate surfaces 412 can better pressurize and attach the protective film to the upper end surface of the product.

[0031] 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 the protective films on both sides of the film sticking platform 2 upward, 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 relative to each other. The arc surface 412 abuts and fits against the outer wall of the product to clamp the product, and the protective film is pressed 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.

[0032] Specifically, the rolling member 32 includes a clamping roller 321 , and the clamping roller 321 is connected to the output end of the jacking drive member 31 through a jacking arm 33 .

[0033] Furthermore, the clamping roller 321 is connected to the lifting arm 33 via a rocker mechanism 34. Specifically, the rocker mechanism 34 includes rocker rods 341 connected to each end of the clamping roller 321, a hinged shaft extending through the middle of the two sets of rocker rods 341 and hingedly connected to the lifting arm 33. The other ends of the two sets of rocker rods are connected by a spring seat 342, which is connected to the lifting arm 33 via an elastic member 343. The spring seat 342 cooperates with the travel limit groove on the rocker rod 341. The elastic return action of the elastic member 343 maintains the clamping roller 321 in tight contact with the two side walls of the product. This rocker mechanism 34 improves the reliability of the contact between the clamping roller 321 and the two side walls of the product.

[0034] like Figure 7 The flip assembly 5 is arranged on one side of the product and includes an adsorption plate 51 located at one end of the product and a flip driving member 52 that drives the adsorption plate 51 to flip along a flip center. The adsorption plate 51 is transmission-connected to the output end of the flip driving member 52. A cavity is provided in the adsorption plate 51, and the cavity is connected to an external device through a vent joint. The vent 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 51 has vacuum adsorption holes, and a groove 511 is provided on the surface of the adsorption plate 51. When the protective film is attached to the film-applying platform 2, the protective film on the upper end surface of the product is adsorbed in the groove 511.

[0035] Furthermore, the groove 511 is defined by the adsorption plate 51 and the mounting plates 54 on either side of the plate 51. Each mounting plate 54 has a travel groove 55. Adjusting the fasteners at different positions in the travel groove 55 allows the groove 511 to be adjusted to different lengths, widths, and shapes. The protective film's length is defined as the direction from the front end toward the rear end of the product, while the direction extending along the product's side walls is defined as the film's width. In this embodiment, the travel groove 55 extends in the film's width direction. Adjusting the fasteners at different positions in the travel groove 55 allows the groove 511's width to be adjusted locally.

[0036] A film-applying roller 53 is installed at one end of the suction plate 51, near the flipping center. This roller is connected to the suction plate 51 via a hinged shaft. Driven by a flipping driver 52, the suction plate 51 flips to various angles around a rotational center. Once the suction plate 51 reaches the film-applying angle, it moves along the length of the product, driving the film-applying roller 53 to roll the protective film from one end of the product to the other. The flipping driver 52 is a flipping motor, the output shaft of which is equipped with a reducer. The suction plate 51 is connected to the reducer via a flipping arm.

[0037] Furthermore, the film-laminating roller 53 is also connected to the adsorption plate 51 through a rocker mechanism 34, wherein the hinge axis of the rocker mechanism 34 is passed through the middle of the two sets of rockers 341 and is hingedly connected to the adsorption plate 51, and the spring seat 342 is connected to the adsorption plate 51 through an elastic member 343, and cooperates with the travel limit groove on the rocker 341. Under the elastic reset action of the elastic member 343, the film-laminating roller 53 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 53 and the upper end surface of the product.

[0038] An X-axis linear module 6 is located on one side of the product, extending from the leading end toward the trailing end. The flipping motor is fixed to the output end of the X-axis linear module 6. Driven by the X-axis linear module 6, it drives the suction plate 51 and film-applying roller 53 along the leading end toward the trailing end of the product, rolling and applying the film. In this embodiment, the X-axis linear module is driven by a linear motor, and the connection between the linear motor and the flipping assembly 5 utilizes a lead screw structure commonly used in the art.

[0039] 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 .

[0040] The film sticking angle and the film pressing angle of the adsorption plate 51 are both determined by setting.

[0041] In this embodiment, a detection component 7 is further provided on one side of the film-sticking platform 2 for detecting the quality of the product protective film. If the detection result is NG, the product information is recorded and uploaded.

[0042] 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 ordinary technicians in this technical field can make several improvements and modifications without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
