[0031] See Figures 1 to 8, this embodiment provides a back cover pressing mechanism, including a conveying component 1, a pre-pressing component 2 and a rolling component 3. The conveying component 1 is capable of conveying the product covered with the back cover backward along the first direction. When the product and the back cover are pressed tightly, the side close to the edge of the conveying component 1 requires a greater pressing force, and the pressing is performed separately by the pre-pressing component 2, which has a better pressing effect and higher efficiency. The pre-pressing component 2 is arranged on the conveying component 1 according to the position where the product and the back cover need to be pressed, that is, the pre-pressing component 2 is arranged on one side of the conveying component 1 along the first direction (the left or right side of the conveying component 1). When the product covered with the back cover is conveyed on the conveying component 1, it will be close to one side edge of the conveying component 1 (the left or right side of the conveying component 1), and the pre-pressing component 2 is arranged on this side edge of the conveying component 1.

[0032] The rolling assembly 3 is also provided on the conveying assembly 1 and is located behind the pre-pressing assembly 2 along the conveying direction. The product covered with the back cover is pre-pressed by the pre-pressing assembly 2 and then conveyed to the rolling assembly 3 to press the product and other positions of the back cover that need to be pressed, that is, the rolling assembly 3 can further press the product and the back cover. The rolling assembly 3 is movably provided on the conveying assembly 1 in the vertical direction through the rolling bracket 7 and can be fastened by fasteners, that is, the height of the rolling assembly 3 relative to the conveying assembly 1 is adjustable, so that this embodiment can be applied to products of different models. In other words, the rolling bracket 7 is movably provided on the conveying assembly 1 in the vertical direction, and the rolling assembly 3 is provided on the rolling bracket 7. After the height of the rolling assembly 3 is adjusted, it can be fastened by fasteners. For example, the fasteners are screws, and the lifting and lowering of the rolling assembly 3 on the conveying assembly 1 can be adjusted by manually adjusting the tightness of the screws. The rolling assembly 3 includes multiple roller drive members 32 and roller units 31 arranged along a second direction. The roller drive members 32 are arranged in a one-to-one correspondence with the roller units 31, and the driving ends of the roller drive members 32 are transmission-connected to the roller units 31. The roller drive members 32 are used to drive the roller units 31 to move in a vertical direction. The roller units 31 are used to further compress the product covered with the back cover. The roller units 31 can be adjusted in height by the roller drive members 32. By adjusting the height of the roller units 31 in different positions, the position of different smart card models can be avoided. Each roller unit 31 fills the conveying assembly 1 along the second direction to avoid some positions that cannot be compressed and improve the applicability of this embodiment for products of different models (different sizes). The first direction is perpendicular to the second direction, and the second direction is a horizontal direction perpendicular to the first direction. The first direction is also the conveying direction (the length direction of the conveying assembly 1), and the second direction is also the width direction of the conveying assembly 1.

[0033] The height of the roller unit 31 can be adjusted by manually adjusting the roller drive 32, or by integrating a PLC controller into the rear cover pressing mechanism and electrically connecting the PLC controller to the roller drive 32. By inputting different product models and sizes into the PLC controller, the corresponding roller drive 32 is controlled to operate, thereby adjusting the height of the roller unit 31. All methods for adjusting the height of the roller unit 31 can be achieved using technical means known in the art.

[0034] In this embodiment, the pre-pressing assembly 2 is first used to pre-press the product and the back cover at locations requiring greater assembly force. The product, covered with the back cover, is then conveyed along a first direction to the rolling assembly 3 by the conveying assembly 1. The rolling assembly 3 then presses the product and the back cover at other locations, achieving a good pressing effect and high efficiency. The height of the rolling assembly 3 can be adjusted to accommodate different product models. The rolling assembly 3 includes a plurality of roller drive members 32 and roller units 31 arranged along a second direction. The roller drive members 32 can drive the roller units 31 to move vertically. By adjusting the height of individual roller units 31 to avoid the position of the smart card, the height of different roller units 31 can be adjusted for different product models. This solution replaces manual labor with equipment, reducing labor intensity and labor costs. A single device can be used to press different product models, reducing production costs. There is no need to replace equipment or parts when processing different products, improving pressing efficiency and being suitable for products of different sizes.

[0035] In one embodiment, Figure 6 As shown, a buffer unit 33 is provided between the driving end of the roller driving member 32 and the roller unit 31 and is connected to each other through the buffer unit 33. The roller unit 31 includes a roller frame 311 and a roller 312. The roller 312 is arranged on the roller frame 311 in a rolling manner along the conveying direction of the product (that is, the axis of the roller 312 is arranged along the second direction). The buffer unit 33 includes an elastic member, a connecting block 331 and a sliding rod 332. The connecting block 331 is connected to the driving end of the roller driving member 32. The roller frame 311 is movably arranged on the rolling bracket 7 in the vertical direction. The first end of the sliding rod 332 passes through the connecting block 331 and is connected to the roller frame 311. The sliding rod 332 and the connecting block 331 can move relative to each other in the vertical direction. The second end of the sliding rod 332 is a limiting end for limiting the second end of the sliding rod 332 from escaping from the connecting block 331. The elastic member is sleeved on the sliding rod 332, and the two ends of the elastic member are respectively against the opposite sides of the roller frame 311 and the connecting block 331.

[0036] The roller drive member 32 can be a pneumatic cylinder, with the driving end of the roller drive member 32 facing downward. The buffer unit 33 connects the driving end of the roller drive member 32 to the roller unit 31. The buffer unit 33 is used to provide a buffer when the roller unit 31 contacts the product covered with the back cover, thereby compressing the product and the back cover tightly while preventing damage to the product.

[0037] The roller unit 31 includes a roller frame 311 and rollers 312. The rollers 312 can be rubber rollers, which prevent damage to the product when pressing it. The rollers 312 rotate in the same direction as the product is conveyed. While pressing the product against the back cover, they convert sliding friction with the product into rolling friction, further preventing damage to the product.

[0038] The buffer unit 33 comprises an elastic member, a connecting block 331, and a sliding rod 332. The bottom end of the sliding rod 332 passes through the connecting block 331 and is connected to the top of the roller frame 311. The sliding rod 332 is able to move vertically relative to the connecting block 331. The top end of the sliding rod 332 is located above the top of the connecting block 331 and can only move upward above the connecting block 331; it cannot pass through the connecting block 331 and move downward. The elastic member, which can be a spring, is mounted on the outer sidewall of the sliding rod 332. The top end of the elastic member abuts the bottom of the connecting block 331, while the bottom end abuts the top of the roller frame 311. The buffer unit 33 has a simple structure and provides excellent buffering effect. When products pass through the roller unit 31, they press upward against the roller 312 and roller frame 311, causing the sliding rod 332 to move upward relative to the connecting block 331. This compresses the elastic member, thus providing a buffering effect. The elastic member generates a downward reaction force, preventing the slide bar 332 from moving upward. After the product passes, the slide bar 332 returns to its original position under the elastic force of the elastic member. In this embodiment, when buffering, the connecting block 331 does not move upward with the slide bar 332, and thus does not affect the roller drive member 32.

[0039] In one embodiment, Figures 6 to 8 As shown, the connecting block 331 is provided with a stepped hole 331a extending vertically therethrough. The slide rod 332 passes through the connecting block 331 through the stepped hole 331a. A step 332a is provided on the outer wall of the second end of the slide rod 332, and the step 332a fits within the stepped hole 331a. When the slide rod 332 is reset, the bottom end surface of the step 332a along the axial direction of the slide rod 332 abuts against the inner bottom wall of the stepped hole 331a, preventing the slide rod 332 from moving further downward and dislodging from the connecting block 331. The top of the connecting block 331 is provided with a stepped hole 331a extending through the thickness thereof. The slide rod 332 fits within the stepped hole 331a. The top end of the slide rod 332 is formed into a step 332a, and the size and shape of the step 332a are the same as those of the stepped hole 331a. The above structure is simple, easy to manufacture, and effectively limits the position of the slide rod 332.

[0040] In one embodiment, Figures 1 to 4 As shown, the rear cover pressing mechanism also includes a positioning assembly 5, which includes a positioning drive 51 and a positioning member 52. The positioning member 52 is arranged on the driving end of the positioning drive 51, and the positioning drive 51 is used to drive the positioning member 52 to move along the second direction. When the product covered with the rear cover is placed on the conveying assembly 1, the position and posture may not necessarily match those of this embodiment, so the pressing effect may be poor due to the poor posture of the product. The positioning drive 51 drives the positioning member 52 to move along the second direction, and the positioning member 52 is arranged along the first direction. The positioning assembly 5 can be arranged on the same side of the conveying assembly 1 as the pre-pressing assembly 2, or on the opposite side. When arranged on the same side, the positioning member 52 is used to pull the product to position it; when arranged on the opposite side, it is used to push the product to position it. The positioning effect is best when the positioning assembly 5 is arranged on the opposite side of the conveying assembly 1. The positioning is performed while the positioning is performed, so as to avoid the posture of the product changing again after positioning and then being conveyed, which affects the pressing effect.

[0041] In one embodiment, Figure 1 As shown, the rear cover pressing mechanism further includes a support frame 4, and the transmission assembly 1 is arranged on the support frame 4. The arrangement of the support frame 4 can prevent the influence of external factors such as dust on the device. In addition, universal wheels can be arranged at the bottom of the support frame 4 to facilitate the movement of the device, thereby improving its applicability to the environment.

[0042] In one embodiment, Figures 1 to 5 As shown, the preloading assembly 2 includes a preloading driver 21 and a pressing member 22. The pressing member 22 is disposed on the driving end of the preloading driver 21, and the preloading driver 21 is used to drive the pressing member 22 to move in a vertical direction. The driving end of the preloading driver 21 can be disposed vertically or slightly tilted, and the specific angle can be set according to the product model and requirements.

[0043] In one embodiment, Figure 5 As shown, the inner side of the pressing member 22 is arc-shaped, that is, the side of the pressing member 22 close to the product along the first direction is arc-shaped, and the pressing member 22 can be a rubber pressing member 22. While being able to press the back cover and the product, it also prevents the pressing member 22 from causing damage to the product.

[0044] In one embodiment, Figures 1 to 4 As shown, the roller units 31 are closely arranged along the second direction, which increases the density of the roller units 31 , that is, reduces the spacing between adjacent rollers 312 , thereby improving the pressing effect between the back cover and the product.

[0045] In one embodiment, the transmission assembly 1 includes a transmission drive member, a load-bearing belt and a rotating roller. The driving end of the transmission drive member is transmission-connected to the rotating roller, and the load-bearing belt is sheathed on the outer circumference of the rotating roller.

[0046] In one embodiment, Figures 1 to 4 As shown, the conveyor assembly 1 is provided with guide assemblies 6 on both sides thereof along the first direction. The guide assemblies 6 include a plurality of guide rollers 61 arranged vertically and arranged along the first direction. The axes of the guide rollers 61 are arranged vertically to guide and cushion the edges of the passing products.

[0047] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical principles disclosed in the present invention are intended to be covered by the claims of the present invention.
