It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the described embodiments of the invention, are within the scope of the invention.

In the prior art, generally, a conveying module is used to respectively discharge a qualified plate and an unqualified plate which are exposed on a conveying module and place the qualified plate and the unqualified plate in different carriers, so that the number of the carriers is increased to increase the occupied space of equipment, and the carriers in different positions increase the stroke of the conveying module for conveying the plates.

Based on the above technical problem, an embodiment of the present invention provides a blanking device for plate exposure, in which a stopping module 60 is installed on a conveying assembly, and a stopping module 60 and a blocking plate 230 are respectively used to stop an unqualified plate b2 and a qualified plate b1 at different positions on the conveying assembly, so that the conveying module 30 is staggered and stacked after moving the plates b at different positions onto a carrier 10, and the unqualified plate b2 can be conveniently taken out of the plates b stacked on the carrier 10; in addition, in the embodiment of the invention, the blanking of the plate can be completed by only using one carrier 10, so that the occupied space of the equipment is reduced, the carrying requirement of the carrying module 30 is reduced, and the blanking efficiency of the blanking device is further improved.

First, a blanking device for plate exposure according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

Specifically, as shown in fig. 1, the blanking device for exposing a plate according to the embodiment of the present invention includes a carrier 10, a conveying module 20, a carrying module 30, and a stopping module 60, wherein the carrier 10 is used for accommodating a plate b after exposure; the conveying module 20 is disposed adjacent to the carrier 10 and is used for conveying the exposed plate b, the conveying module 20 includes a baffle 230 and a conveying component, the baffle 230 is located at the end of the conveying component to stop the exposed plate conveyed on the conveying component; the carrying module 30 is located above the transferring module 20 and is used for picking up and moving the plate material on the transferring module 20 to the carrier 10; the stopping module 60 is installed on the conveying assembly near the baffle 230, and is used for stopping the unqualified exposed plate conveyed on the conveying assembly, so that the unqualified exposed plate is moved to the carrier 10 and then stacked with the qualified exposed plate in a staggered manner.

That is, the conveying module 30 is located above the conveying assembly, and the conveying module 30 picks up the sheet material b from the same position on the conveying assembly each time, and when the position of the sheet material b on the conveying assembly is different, the sheet material b placed on the carrier 10 is displaced, that is, the sheet material b1 which is stacked in a staggered manner is displaced from the unqualified sheet material b2 shown in fig. 2.

It should be understood that: after the plates on the conveying assembly are stopped by the stopping module, the position of the plates on the conveying assembly is different from the position of the plates on the conveying assembly stopped by the baffle 230, and the larger the difference between the plates stopped by the two modes is, the larger the dislocation distance between the plates on the carrier 10 is, and the dislocation distance can be set according to specific situations, which is not limited in the embodiment of the present invention.

It should be noted that: the sheet passes through the exposure and then has unqualified sheet, but the unqualified sheet accounts for extremely low proportion of the total sheet, so that the qualified sheet and the unqualified sheet stacked in a staggered way on the carrier 10 are easy to distinguish.

In one embodiment, as shown in fig. 1, the conveying assembly includes a base 210, a first driving assembly 220 and a roller 240, the first driving assembly 220 is fixedly installed on the base 210, the roller 240 is connected to the first driving assembly 220, the plate is placed on the roller 240, and the plate moves along with the roller 240 under the driving force of the first driving assembly 220. The first drive assembly 220 is preferably, but not limited to, a motor drive.

In an embodiment, as shown in fig. 3, the stopping module 60 includes a second driving assembly 610, a blocking lever 630 and a fixing bracket 620, the fixing bracket 620 is fixedly connected to the base 210, the second driving assembly 610 is fixedly mounted on the fixing bracket 620, the blocking lever 630 is mounted on the second driving assembly 610, the blocking lever 630 is located between adjacent rollers 240, and the blocking lever 630 reciprocates in a vertical direction under the driving force of the second driving assembly 610, so that the blocking lever 630 moves above or below the rollers 240. The second driving assembly 610 is preferably driven by a cylinder, but is not limited thereto.

That is, the fixing bracket 620 is located below the rollers 240 and fixedly connected to the base 210, and the stopper 630 moves to above the rollers 240 through the gap between adjacent rollers 240 under the driving force of the second driving unit 610 to block the plate conveyed on the rollers 240.

The stopping module 60 further includes a sensor, when the exposure machine detects an unqualified plate, the exposure machine sends a signal to the sensor, and the sensor uses the second driving component 610 to drive the stop lever 630 to move upwards to stop the unqualified plate based on the signal, so that the position of the unqualified plate carried to the carrier 10 is different from that of the qualified plate.

In an embodiment, as shown in fig. 4, the carrier 10 includes a first carrying surface 110 and a second carrying surface 120 that are integrally formed, the first carrying surface 110 and the second carrying surface 120 form a containing groove for placing the plates, and a plurality of the plates are stacked on the first carrying surface 110; wherein an angle between the first and second carrier surfaces 110 and 120 is an obtuse angle.

That is, after the plurality of plates are placed in the accommodating groove, the first carrying surface 110 is stressed, and the plurality of plates form a certain inclination angle with the horizontal direction. The range of the inclination angle is preferably less than 70 ° and greater than 45 °, and the range of the inclination angle enables the first carrying surface 110 and the second carrying surface 120 of the carrier 10 to be stressed uniformly and prevents the bottom plate from being damaged when the carrier 10 carries a large number of plates.

Further, an angle a is formed between the first and second carrier surfaces 110 and 120, and the angle a is greater than 90 ° and less than 120 °.

That is, the carrier 10 with the angle range makes the pressure of the first carrying surface 110 and the second carrying surface 10 for carrying the plate material more uniform. Conversely, when the angle is greater than 120 °, the first carrying surface 110 will carry a larger pressure, which reduces the stability of the carrier 10 when receiving a large batch of plates.
