[0020] The technical solution and technical effects of the present invention are further described in detail below in conjunction with the accompanying drawings of the present invention.

[0021] It should be noted that, in the description of the present invention, the terms "above", "below", "left", "right" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention. In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be directly connected, or indirectly connected through an intermediate medium, or it can be the internal connection of two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] like Figure 1 and Figure 2 As shown, the utility model provides a conveying and straightening device, which includes a belt conveying mechanism 10 and a pushing member 20; the conveying mechanism conveys along the Y direction, including a plurality of synchronous belts 11 arranged at intervals along the X direction; two straightening stations 40 are provided on the conveying surface of the conveying mechanism at intervals along the X direction, and each straightening station 40 is provided with a pushing member 20 around it, and each pushing member 20 can move toward its corresponding straightening station 40, and the pushing member 20 located at one end of the straightening station 40 and adjacent to the loading end of the belt conveying mechanism 10 can be raised and lowered, wherein the X direction is perpendicular to the Y direction.

[0023] When in use, the pusher 20 (i.e. located near the feeding end of the belt conveyor mechanism 10) Figure 1 The lowest pusher 20 in the conveying mechanism descends to a position below the conveying surface of the synchronous belt 11. The pusher 20 is interspersed between the synchronous belts 11. Two glass plates 50 arranged side by side along the X direction are conveyed from the loading end of the belt conveyor mechanism 10 to the two straightening stations 40. The pusher 20 adjacent to the loading end of the belt conveyor mechanism 10 rises to a position above the conveying surface of the synchronous belt 11. The pushers 20 around the two straightening stations 40 move toward the glass plates 50 and push the glass plates 50 to a preset position so that the glass plates 50 are straightened.

[0024] In the present invention, the belt conveying mechanism 10 also includes a transmission shaft 12 and a motor. The motor is connected to the transmission shaft, and the transmission shaft 12 is connected to all the synchronous belts 11, so that the motor can drive all the synchronous belts 11 to rotate at the same time. The lifting and lowering action of the pusher 20 can be controlled by a cylinder, and the horizontal pushing of the glass plate 50 by the pusher 20 can be controlled by an electric cylinder and / or a cylinder. The horizontal movement stroke of the pusher 20 can be set as needed to be compatible with glass plates of different sizes. It should be noted that the conveying and straightening device provided by the present invention is suitable for straightening glass plates of smaller sizes, such as glass plates used for balcony photovoltaic modules. Balcony photovoltaics is a photovoltaic system installed on a balcony. The photovoltaic modules used for balcony photovoltaics are usually only half the size of traditional photovoltaic modules or smaller.

[0025] In the present invention, the pushing member 20 can be in point contact or surface contact with the glass plate 50. Preferably, the pushing member 20 is a roller 21 that can rotate horizontally. The roller 21 is in point contact with the glass plate 50, and when it contacts the glass plate 50 and causes relative displacement, the friction force generated by the rotation of the roller 21 is smaller, which is conducive to the glass plate 50 being quickly pushed to the preset position.

[0026] like Figure 3 As shown, in the present invention, each straightening station 40 is provided with two rollers 21 at one Y-direction end and one or two rollers 21 at the other Y-direction end. Along the Y-direction, the roller 21 at one Y-direction end of each straightening station 40 is on either side of or between the roller 21 at the other Y-direction end. The rollers 21 at both ends of the straightening station 40 correspond to the long sides of the glass sheet 50. Two straightening stations 40 are each provided with two rollers 21 at their adjacent ends, and two straightening stations 40 are each provided with one roller 21 at their distal ends. Along the X-direction, one roller 21 at one X-direction end of each straightening station 40 is located between the two rollers 21 at the other X-direction end. This allows the rollers 21 surrounding the glass sheet 50 to adjust its angle in real time as it is pushed, facilitating accurate pushing of the glass sheet 50 to the preset position.

[0027] Furthermore, when in the initial position, the four rollers 21 between the two straightening stations 40 are arranged linearly in the Y direction, wherein the two rollers 21 in the middle correspond to one straightening station 40, and the two rollers 21 at both ends correspond to another straightening station 40. On the one hand, the force on one side of the glass plate 50 can be balanced, and on the other hand, the space occupied by the conveying straightening device in the X direction can be reduced.

[0028] In the present invention, a vertical limit switch 13 is provided at each straightening station 40 along the Y direction. The vertical limit switch 13 located at each straightening station 40 is used to detect whether the glass plate 50 enters the straightening station 40 .

[0029] In the present invention, the conveying and straightening device also includes a fork transport mechanism 30 arranged at the discharge end of the belt conveyor mechanism 10. The fork transport mechanism 30 is docked with the belt conveyor mechanism 10 and is used to fork-transport the glass plate 50 located at the straightening station 40, and transport the straightened glass plate 50 to the next station. The glass plate 50 is transported by fork transport, and the transportation accuracy is high, which can ensure that the glass plate 50 is transported to the designated position.

[0030] Specifically, the fork transport mechanism 30 includes a moving plate 31, a lifting plate 32, and fork tines 33. The moving plate 31 can move along the Y direction. The lifting plate 32 is liftably connected to both ends of the moving plate 31. The fork tines 33 are fixed to the lifting plate 32 and can extend below the straightening station 40. In this embodiment, lifting drive members 34 are provided at both ends of the moving plate 31. The driving ends of the lifting drive members 34 are fixed to the lifting plate 32. Preferably, the lifting drive members 34 are screw transmission members. A motor is provided on the moving plate 31, and the motor is simultaneously driven by the two screw transmission members.

[0031] In the present invention, a pusher 20 located at one end of the straightening station 40 and adjacent to the fork conveyor mechanism 30 is mounted on a lifting plate 32. This pusher 20 is positioned higher than the fork tines 33. This pusher 20 moves with the lifting plate 32, preventing interference with the fork conveyor mechanism 30 during operation when the pusher 20 is positioned elsewhere. A cylinder is also mounted on the lifting plate 32 to drive this pusher 20 to straighten the glass sheet 50. Other pushers 20 are mounted on the bracket on which the timing belt 11 is mounted.

[0032] The above disclosure is only a preferred embodiment of the present invention, and it is certainly not intended to limit the scope of the rights of the present invention. A person skilled in the art can understand that all or part of the processes of the above embodiment and equivalent changes made in accordance with the claims of the present invention are still within the scope of the present invention.
