At the same time, the sticker is prone to sticking to the workbench during affixing, which makes it impossible to affix the nameplate normally, thus affecting the efficiency of affixing. Summary of the Invention

[0005] The present invention aims to overcome the defects in the prior art and provide a photovoltaic nameplate sticker anti-sticking transmission device and its usage method that can adjust the sticker height and prevent the sticker from sticking.

[0006] To achieve the above-mentioned objectives, the present invention adopts the following technical solution: a photovoltaic nameplate sticker anti-sticking transmission device, comprising a support component and a lifting component for adjusting the height of the support component; the top of the support component is provided with a grid plate for placing stickers, and the bottom of the grid plate is equipped with a wheel conveying mechanism for driving the stickers; the lifting component is provided with a lifting mechanism for controlling the lifting and lowering of the wheel conveying mechanism; the lifting mechanism includes a cylinder and a push plate connected to the output end of the cylinder, the push plate being connected to the wheel conveying mechanism; the lifting component includes a support column and a limiting slider slidably connected to the support column, the limiting slider being connected to the support component; a limiting member for limiting the lifting and lowering of the support component is provided between the lifting component and the support component; photoelectric sensors for detecting nameplate stickers are provided at both opposite ends of the wheel conveying mechanism.

[0011] As a preferred embodiment of the present invention, a piston rod is provided on the output end of the cylinder, and the top end of the piston rod is connected to the push plate.

[0012] In a preferred embodiment of the present invention, the limiting slider is connected to the lifting platform, and a support groove is formed on the support column to cooperate with the limiting slider, and the support groove is set along the height direction of the support column.

[0013] As a preferred embodiment of the present invention, the limiting member includes a bolt connected to the lifting platform, a nut fitted on the bolt, a connecting plate connected to the bolt at the top of the support column, the nut being located below the connecting plate and abutting against the connecting plate.

[0015] A method for using a photovoltaic nameplate sticker anti-adhesion transmission device includes the following steps:

[0017] 2. The lifting mechanism is activated, pushing the wheel set conveyor mechanism to rise to the designated working position and conveying the nameplate sticker forward;

[0018] 3. After the photoelectric sensor at the tail of the wheel conveyor detects the nameplate sticker, the wheel conveyor stops, the lifting mechanism drives the wheel conveyor back to its original position, the nameplate sticker falls onto the grid plate and is attracted away, a new sticker is placed on the grid plate, and the above steps are repeated.

[0019] 4. When the nameplate sticker transmission height is not suitable, adjust the limit component to ensure that the height of the wheel set conveyor mechanism meets the transmission height of the nameplate sticker.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. The stickers are conveyed through a wheel conveyor mechanism, which prevents the stickers from sticking to the grid plate, ensuring stable sticker delivery.

[0030] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0031] like Figures 1-6 As shown, a photovoltaic nameplate sticker anti-sticking transmission device includes a support assembly 3 and a lifting assembly 4 for adjusting the height of the support assembly 3.

By adjusting the lifting component 4, the height of the support component 3 and the adjusting mechanism 2 can be raised synchronously. At the same time, the limiting component 404 is connected between the support component 3 and the lifting component 4. During the lifting process of the support component 3, the limiting component 404 limits the lifting height of the support component 3 to prevent the support component 3 from being raised too high.

[0033] The stickers are conveyed by the wheel conveyor mechanism 1, which prevents the stickers from sticking to the grid plate 301, ensuring stable sticker delivery.

At the same time, the height of the wheel conveyor mechanism 1 is adjusted by the lifting mechanism 2, causing relative movement with the grid plate 301, which can prevent the stickers from sticking to the support component 3. This ensures that the height of the entire device meets the requirements for sticker labeling and improves labeling efficiency.

[0034] The wheel conveyor mechanism 1 includes several synchronously rotating shafts 102 and a drive motor 104 that drives the several rotating shafts 102 to rotate.

Furthermore, the pulleys 1021 are located at the outer end of the bearings 1023 and are located outside the mounting bracket 101. The pulleys 1021 are double grooved pulleys. Two adjacent pulleys 1021 are connected by the synchronous belt 1022, thereby realizing the connection of all pulleys 1021 and thus realizing the synchronous rotation of all rotating shafts 102.

[0039] A drive pulley 1041 is connected to the output end of the drive motor 104. A synchronous belt 1022 that drives several pulleys 1021 to rotate synchronously is also connected between the drive pulley 1041 and the pulley 1021.

The push plate slider 2021 plays a limiting role on the push plate 202, restricting the four degrees of freedom of the push plate 202: left, right, and front and back.

[0044] The limiting slider 402 is connected to the lifting platform 303, and a support groove 4011 is formed on the support column 401 to cooperate with the limiting slider 402.

The nut 4042 is located below the connecting plate 403. When the support assembly 3 moves upward, the bolt 4041 and the nut 4042 move synchronously. When the support assembly 3 rises to a certain height, the nut 4042 abuts against the connecting plate 403, thereby limiting the support assembly 3 from rising further, thus achieving the limitation of the lifting height of the support assembly 3.
