Description

TECHNICAL FIELD

[0001] The present application relates to the field of photovoltaic glass unloading, in particular to a device for unloading photovoltaic embossed glass. BACKGROUND

[0002] In the production process of photovoltaic embossed glass, the glass is cut into different sizes of rectangular plates after forming, and is transported to the rear end station for stacking and packaging through the glass conveying line.

[0003] There are various ways of stacking and packaging, and no matter which way of stacking is used, the glass plates horizontally placed on the main line need to be vertically placed on the L-shaped frame. At present, mainstream manufacturers are equipped with 6-axis robots and their auxiliary equipment to realize the full-automatic grabbing and stacking of the glass plates on the production line. According to the situation of each manufacturer, the use of robots to stack the glass is divided into two types: down grabbing and up grabbing.

[0004] However, since the upper surface of the photovoltaic embossed glass is a smooth surface (i.e. the light-receiving surface, front surface), and the lower surface is an embossed surface (i.e. the back surface), in actual production, if the robot grabs the glass from the smooth surface, it will be more difficult to clean the suction cup marks left by the embossed surface, which will result in the product not meeting the customer's aesthetic requirements for photovoltaic glass. Therefore, when unloading the photovoltaic embossed glass, the glass is grabbed from the back surface, i.e. the glass is grabbed from the bottom.

[0005] The down grabbing method in the prior art is divided into the following two ways:

[0006] The first way is to configure a down taking plate station beside the main line roller (photovoltaic embossed glass plate conveying roller), the photovoltaic embossed glass plates transported by the main line roller are conveyed to the down taking plate station through the overpass roller, then the robot grabs the photovoltaic embossed glass plates from the bottom up, and then the photovoltaic embossed glass plates are stacked and packaged.

[0007] The other way is to install a 45-degree plate turning machine on the main line roller (photovoltaic embossed glass plate conveying roller), when the photovoltaic embossed glass plates transported on the main line roller reach the position of the plate turning machine, the plate turning machine turns the glass up by 45 degrees, the suction cup of the robot sucks the back surface of the photovoltaic embossed glass plate from the position of the included angle space, then the photovoltaic embossed glass plate is grabbed out obliquely, and then the photovoltaic embossed glass plate is stacked and packaged.

[0008] Although the down taking plate station method is the most common and mature, it requires more space and cannot be used when the workshop space is small and the space beside the main line roller is insufficient. The plate turning machine method requires high performance of the equipment, and because the photovoltaic embossed glass plate needs to be kept at 45 degrees on the plate turning machine without falling, a vacuum suction cup is needed to adsorb the photovoltaic embossed glass plate on the plate turning machine. The whole equipment structure is complex, the reliability is low, the efficiency is low, and the land occupation is large. Summary of the Invention

[0009] The present invention aims to overcome the shortcomings of the prior art by providing a sheet-cutting device for photovoltaic patterned glass.

[0010] This application provides the following technical solution:

[0011] A device for unloading photovoltaic patterned glass includes a glass sheet conveying roller conveyor on which photovoltaic glass sheets are transported. A frame is provided on one side of the glass sheet conveying roller conveyor. The device is characterized by: vertically distributed linear reciprocating components on the frame; corresponding glass brackets connected to the linear reciprocating components; inductive switches corresponding to the photovoltaic glass sheets mounted on both sides of the glass sheet conveying roller conveyor on one side of the frame via brackets; a retractable glass blocking component on the glass sheet conveying roller conveyor on the other side of the frame; and a control module that forms an electrical signal connection and control mechanism with the linear reciprocating components, inductive switches, and retractable glass blocking component.

[0012] On the other side of the glass sheet conveyor roller, there are unloading robots distributed opposite to the frame.

[0013] Based on the above technical solutions, the following further technical solutions are also possible:

[0014] The linear reciprocating assembly includes a pair of longitudinal slide rails distributed on the frame, a servo motor and a reducer combination as a drive mechanism at the bottom of the frame, a lower pulley on the output shaft of the reducer, an upper pulley correspondingly on the top of the frame, and a corresponding transmission belt on the upper and lower pulleys.

[0015] A corresponding slider is provided on the longitudinal slide rail, one end of the glass bracket is connected to the slider, and the transmission belt is connected to the glass bracket.

[0016] The glass bracket includes a crossbeam spanning a linear reciprocating assembly, a set of first cantilever arms on the crossbeam, and a second cantilever arm connected to one end of each first cantilever arm. The first cantilever arms and the second cantilever arms are not in the same horizontal plane.

[0017] The drive belt has an open-loop structure, and its two ends are connected together by toothed clamps, L-clamps and bolts. The other side of the toothed clamps and L-clamps is connected to the glass bracket.

[0018] Both ends of the frame are equipped with limiting plates that correspond to and cooperate with the linear reciprocating components.

[0019] The second cantilever is staggered with the rollers on the glass plate conveyor.

[0020] The retractable glass blocking assembly includes a longitudinal telescopic device on the roller frame below the rollers of the glass plate conveying roller. A blocking plate distributed along the width direction of the glass plate conveying roller is installed on the output shaft of the longitudinal telescopic device. The upper end of the blocking plate can extend longitudinally out of the glass plate conveying roller or retract downward into the glass plate conveying roller.

[0021] Advantages of the invention:

[0022] This invention features a simple structure, low manufacturing cost, and advantages such as low failure rate, high stability, and ease of maintenance. Its compact structure requires less workshop space than a lower-level pick-up platform, making it suitable for space-constrained production conditions. It boasts high operating efficiency, reducing the need for robots and saving on equipment investment and space usage. It quickly and accurately lifts photovoltaic glass panels from the glass panel conveyor rollers, allowing the suction cups on the industrial robot arm to easily adhere to the back of the photovoltaic glass panel, facilitating subsequent stacking and packaging operations. This ensures that no suction cup marks are left on the smooth surface of the photovoltaic glass panel during the picking process. Attached Figure Description

[0028] like Figures 1-5 As shown, a sheet-unloading device for photovoltaic patterned glass includes a glass sheet conveying roller 7 on which a photovoltaic glass sheet 8 is transported. A frame 1 is provided on one side of the glass sheet conveying roller 7. Vertically distributed linear reciprocating components 2 are provided on the frame 1 facing the glass sheet conveying roller 7.

[0029] The linear reciprocating assembly 2 includes a pair of longitudinal slide rails 2a, on which corresponding sliding blocks 2b are provided. A servo motor 15 and a reducer 14 are mounted on a base plate 1a at the bottom of the frame 1 as a drive mechanism. The output shaft of the reducer 14 is connected to the base plate 1a via two self-aligning bearings 1b to evenly distribute the radial load. A lower pulley 16a is connected to the output shaft.

[0030] A set of lifting feet 1c is connected to the base plate 1a at the bottom of the frame 1. A pair of support feet 1d are also connected to the frame 1 above the base plate 1a. One end of each support foot 1d has an elongated hole 1e, within which a locking bolt is installed to connect and engage with the frame 1. The support feet 1d form a triangular support for the frame 1. Furthermore, the lifting feet and the elongated hole allow for some adjustment of the frame's posture, enabling the frame to be stably installed even on uneven ground.

[0031] An upper pulley 16 is connected to the top of the frame 1. Corresponding drive belts 16c are mounted on the upper pulley 16 and the lower pulley 16a. The drive belt 16c is a circular arc tooth synchronous belt with an open-loop structure. At the open loop, the two ends of the drive belt 16c are connected together by a pair of toothed clamps 20 and L-shaped clamps 19, along with bolts, to form a closed-loop structure. The L-shaped clamps 19 are L-shaped. The toothed clamps 20 and L-shaped clamps 19 employ a tension adjustment design. The two L-shaped clamps 19 are connected by two bolts, allowing for adjustment of the tension of the synchronous belt 8 while simultaneously ensuring force balance. The other side of the toothed clamps 20 and L-shaped clamps 19 is connected to the glass bracket 3.

[0032] The glass bracket 3 includes a crossbeam 3a that spans the linear reciprocating assembly 2. One side of the crossbeam 3a is connected to the toothed clamp 20 and the L-clamp 19, thereby driving the glass bracket 3 to move up and down along the longitudinal slide rail through the linear reciprocating assembly 2.

[0033] A set of horizontally extending first cantilever 3b is provided on the crossbeam 3a. Each of the extended ends of the first cantilever 3b has a downwardly extending bend 13b, making the first cantilever 3b an L-shaped structure. A second cantilever 3c is connected to the lower end of the bend 13b, and the second cantilever 3c is staggered with the rollers 7a on the glass plate conveyor 7. Thus, when the glass support 3 is in the start position, the first cantilever 3b rests on the upper surface of the support of the glass plate conveyor 7, while the second cantilever 3c extends downwards below the rollers of the glass plate conveyor 7. Therefore, when the glass plate conveyor 7 is locating and transferring the photovoltaic glass plate 8, the second cantilever 3c will be located below the photovoltaic glass plate 8.

[0034] The axis of the second cantilever 3c is in the same direction as the axis of the first cantilever 3b. The second cantilever 3c is located in the horizontal plane below the first cantilever 3b, so that the first cantilever 3b and the second cantilever 3c are distributed in a stepped manner. Both ends of the slider 2b are provided with limiting buffer blocks 2c, and the frame 1 at both ends of the longitudinal slide rail 2a is provided with limiting plates 2d that correspond to and cooperate with the limiting buffer blocks 2c. A reinforcing tie rod 1f is provided on the back of the frame 1.

[0035] On both sides of the glass plate conveying roller 7 on one side of the frame 1, there are induction switches 4 that correspond to and cooperate with the photovoltaic glass plate 8 via brackets 4a. The induction switches 4 are photoelectric induction switches.

[0036] A retractable glass blocking assembly is provided on the glass conveyor roller 7 on the other side of the frame 1. The glass blocking assembly includes a longitudinal telescopic device, such as a cylinder (not shown in the figure), located on the roller frame below the rollers of the glass conveyor roller 7. A blocking plate 5 is mounted on the output shaft of the longitudinal telescopic device, distributed along the width direction of the glass conveyor roller 7 and located between two adjacent rollers. This allows the blocking plate 5 to extend out of the glass conveyor roller 7 under the control of the telescopic device, blocking the photovoltaic glass panel 8 transferred there by the glass conveyor roller 7, and accurately lifting the photovoltaic glass panel 8 when the glass support 3 is raised.

[0037] The control box of the glass plate conveyor roller 7 is equipped with a control module that forms an electrical signal connection and control mechanism with the linear reciprocating assembly, the induction switch 4, and the retractable glass blocking assembly.

[0038] On the other side of the glass plate conveying roller, there is a glass unloading robot 21 distributed opposite to the frame 1.

[0039] Work process:

[0040] First, the control module controls the combination of servo motor and reducer as the drive mechanism to drive the glass bracket to the starting position. Then, the control module sends a signal to the controller of the glass plate conveying roller, and the glass plate conveying roller starts to transfer the photovoltaic glass plate.

[0041] When the photovoltaic glass panel enters the detection area of ​​the inductive switch, the inductive switch sends an electrical signal to the control module and begins a countdown for the longitudinal telescopic device. When the countdown ends, the photovoltaic glass panel is just above the glass bracket, and at the same time, the longitudinal telescopic device raises a blocking plate to limit the movement of the photovoltaic glass panel.

[0042] Simultaneously, the control module sends signals to both the controller and drive mechanism of the glass plate conveyor rollers to stop the glass plate conveyor rollers. The drive mechanism then lifts the glass support, vertically detaching the photovoltaic glass plate from the glass plate conveyor rollers. Simultaneously, the longitudinal extension / retraction causes the blocking plate to retract.

[0043] Then, when the glass support is raised to the top, the control module sends a signal to the industrial robot located on the opposite side of the support. The suction cup on the robotic arm of the unloading robot 21 picks up the photovoltaic glass panel from below. Then the glass support is raised and lowered, so that the photovoltaic glass panel is removed from the glass support. At the same time, the robotic arm of the unloading robot 21 flips and moves to the stacking and packaging station, releases the photovoltaic glass panel and stacks it on the glass placement rack. After a certain number of photovoltaic glass panels are reached, the glass placement rack is moved to the next station for packaging.

[0044] When the robotic arm of the next film robot starts to rotate and move, it will also send an electrical signal to the control module. At this time, the control module will control the servo motor in the drive mechanism to reverse and drive the glass bracket to descend to the starting position again. At the same time, the control module will send a signal to the controller of the glass plate conveying roller again, and the glass plate conveying roller will start to transfer the photovoltaic glass plate again.

[0045] If several of these devices and corresponding industrial robots are installed on both sides of a long glass plate conveying roller, the glass plate unloading operation can be carried out without stopping the glass plate conveying roller by having each combination work alternately.
