Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic cells, in particular to a glass horizontal correction device for a glass loading machine. Background Art

[0002] At present, glass trays in the photovoltaic industry usually adopt recycling and reuse to reduce costs. After being used multiple times, some trays are deformed or otherwise damaged, and it is easy to cause the four corners of the trays not to be on the same horizontal plane. When abnormal trays are used in the workshop for production, it often occurs that the glass is not horizontal due to the non-horizontal tray, which affects the normal adsorption and grasping of the glass loading machine, resulting in vacuum alarms of the glass loading machine or the glass falling during the elevation process, affecting production capacity and increasing losses. Otherwise, it is only possible to manually add pads at the bottom of the tray to keep the glass horizontal for normal production. This manual adjustment method is neither safe nor easy to adjust in place, resulting in a great waste of costs.

[0003] The four corners of traditional wooden trays are formed by stacking wooden blocks, with low horizontal accuracy. When recycled for the second time, they are easily deformed and damaged at the four corners and uneven in horizontal position due to being soaked by rain, dragged and bumped, etc. Most glass manufacturers in the industry use wooden trays, and there will be uneven levels of the entire tray of glass during component production. This problem urgently needs to be solved. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is: in order to overcome the deficiencies of the prior art, the utility model provides a glass horizontal correction device for a glass loading machine, which uses a photoelectric sensor in cooperation with a lifting motor to detect the horizontal degree of the glass surface by the photoelectric sensor when sucking the glass, and then adjusts the heights of the four corners of the bottom tray through the lifting motor according to the signal of the photoelectric sensor, so as to horizontally correct the glass located at the top.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a glass horizontal correction device for a glass loading machine, used for adjusting the heights of the four corners of the bottom of the tray. A plurality of glasses are stacked in the tray, and it includes a robotic arm, a distance detection photoelectric mechanism, and a photoelectric type deviation rectifier; a suction cup device is fixed at the lower end of the robotic arm; the distance detection photoelectric mechanism is fixed on the lower end surface of the robotic arm and is respectively arranged corresponding to the four corners of the topmost glass. The distance detection photoelectric mechanism includes a distance detection photoelectric probe and a photoelectric sensor. The distance detection photoelectric probe detects the photoelectric distance between it and the glass and transmits the signal of the photoelectric distance to the photoelectric sensor; the photoelectric type deviation rectifier is respectively arranged at the installation positions below the four corners of the glass. The photoelectric type deviation rectifier includes a lifting motor and a signal receiving sensor. The output end of the lifting motor supports the tray, and the signal receiving sensor controls the height difference between the output end of the lifting motor and the installation position after receiving the signal of the photoelectric sensor.

[0006] In the above solution, to address the problem of the four corners of the pallet being deformed, the glass to be loaded at the top is used as the reference for horizontal detection. When the top glass is not horizontal, the photoelectric type alignment device below is actuated to adjust the height of the four corners, achieving the horizontal state of the top glass. This can effectively adapt to and adjust wooden pallets or recycled pallets for four-corner error correction and leveling. The adjustment process is convenient and fast, applicable to the adjustment of different pallets, and has high loading compatibility.

[0007] Furthermore, the glass horizontal correction device includes a vertically arranged working base, and the robotic arm is arranged on the working base. The working base provides a supporting and mounting structure for the robotic arm.

[0008] Furthermore, the glass horizontal correction device includes at least two alignment devices. Each alignment device includes an alignment column and an alignment cylinder fixed on the alignment column. Among the at least two alignment devices, there are a first alignment device and a second alignment device. The alignment column of the first alignment device is fixed on the working base, and the output direction of the alignment cylinder of this device is parallel to the glass plane and the output end points to the side of the pallet. The output direction of the alignment cylinder of the second alignment device is in the same plane as and perpendicular to the output direction of the alignment cylinder of the first alignment device. Through the action of the alignment devices, the pallet can be pushed into place in the horizontal direction, facilitating the alignment of the pallet with a skewed loading position.

[0009] Even further, the glass horizontal correction device includes a mounting base. The working base is fixed on the mounting base, and the alignment column of the second alignment cylinder and the lifting motor of the photoelectric alignment device are both fixed on the mounting base.

[0010] Furthermore, the suction cup device includes a suction cup fixing frame. A number of telescopic cylinders are arranged on the suction cup fixing frame, and a vacuum suction cup is fixed at the output end of the telescopic cylinder. The vacuum suction cup is connected to a vacuum pump through a vacuum tube in an air path.

[0011] Even further, telescopic cylinders are respectively arranged on the suction cup fixing frame corresponding to the glass, and a vacuum suction cup is fixed at the output end of each telescopic cylinder.

[0012] Even more further, a vacuum degree sensor is also provided on the vacuum suction cup. The vacuum degree sensor detects the levelness of the vacuum suction cup. The suction cup device is responsible for pressing down to grab, transfer, and release the glass. During this process, if the glass cannot be horizontally sucked, there is a risk of dropping. Therefore, the vacuum degree sensor is designed to monitor in real time.

[0013] Preferably, the glass horizontal correction device includes an intelligent control system. The photoelectric sensor, signal receiving sensor, and vacuum degree sensor are respectively connected to the intelligent control system by signals. After the signal of the photoelectric sensor is transmitted to the intelligent control system, it is converted into an action signal corresponding to the photoelectric type rectifier by the intelligent control system, and this action signal is transmitted to the signal receiving sensor. The intelligent control system receives the signal of the vacuum degree sensor and provides an alarm indication when the vacuum chuck is not horizontal.

[0014] The beneficial effects of the present utility model are as follows. A glass horizontal correction device supporting a glass loading machine provided by the present utility model has a reasonable structural design. By using the distance detection photoelectric mechanism to detect the distance between the distance detection photoelectric probe and the uppermost glass, and cooperating with the photoelectric rectifier, the heights of the four corners of the bottom tray can be adjusted respectively to correct the levelness of the uppermost glass, effectively solving the four-corner error of the tray, effectively ensuring the levelness of loading, improving the compatibility of the machines supporting the glass loading machine, and enabling the tray to be recycled twice, thus reducing production costs.

[0018] Now, the present utility model will be further described in detail in conjunction with the drawings. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present utility model in a schematic manner. Therefore, they only show the components related to the present utility model. Directions and references (such as up, down, left, right, etc.) can only be used to assist in the description of the features in the drawings. Therefore, the following detailed description is not adopted in a restrictive sense, and the scope of the claimed subject matter is only defined by the appended claims and their equivalent forms.

[0019] As Figure 1 shown, a glass horizontal correction device supporting a glass loading machine is the optimal embodiment of the present utility model, which is used to adjust the heights of the four corners of the bottom of the tray. The tray usually uses a wooden tray or a recycled tray twice, and there are problems such as deformation of the four corners and uneven horizontal positions. The glass to be loaded is stacked in the tray, and the robotic arm 2 sucks the glass from top to bottom in turn and then loads it.

[0020] The glass horizontal correction device provided in this embodiment includes a mounting base 7, a working base 1, and a robotic arm 2. The working base 1 is vertically fixed on the mounting base 7, and the robotic arm 2 is disposed on the working base 1. A suction cup device is provided on the lower end surface of the robotic arm 2.

[0021] Specifically, the suction cup device includes a suction cup fixing frame. A plurality of telescopic cylinders are spaced apart on the suction cup fixing frame. A vacuum suction cup is fixed to the output end of the telescopic cylinder. The vacuum suction cup is connected to the vacuum pump through a vacuum tube in an air path. Telescopic cylinders are respectively provided corresponding to the glass on the suction cup fixing frame, and a vacuum suction cup is fixed to the output end of each telescopic cylinder. A vacuum sensor is further provided on the vacuum suction cup. The vacuum sensor detects the level of the vacuum suction cup. The suction cup device is responsible for pressing down to grasp, transfer, and release the glass. During this process, if the glass cannot be horizontally sucked, there is a risk of dropping. Therefore, a vacuum sensor is designed to monitor the level of the glass in real time, thereby reducing the dropping risk during the feeding process.

[0022] Based on the feeding of the above suction cup device, this embodiment further provides optoelectronic alignment devices 5 respectively at positions below the four corners of the glass, and a distance detection optoelectronic 6 mechanism is designed on the lower end surface of the robotic arm 2. In this embodiment, the distance detection optoelectronic 6 mechanism is fixed on the lower end surface of the suction cup fixing frame and is also provided corresponding to the four corners of the glass respectively, the same as the optoelectronic alignment device 5.

[0023] Specifically, each distance detection optoelectronic 6 mechanism includes a distance detection optoelectronic 6 probe and an optoelectronic sensor. The distance detection optoelectronic 6 probe detects the optoelectronic distance between it and the glass and transmits the signal of the optoelectronic distance to the optoelectronic sensor. The optoelectronic alignment devices 5 are respectively provided at the installation positions below the four corners of the glass. The optoelectronic alignment device 5 includes a lifting motor and a signal receiving sensor. After receiving the signal of the optoelectronic sensor, the signal receiving sensor controls the output end of the lifting motor to adjust the height difference from the installation position. The output end of the lifting motor is used to support the tray. When it is necessary to calibrate and adjust the level of the tray, the lifting motor is lifted or lowered for adjustment, so that the distances between the glass and the four corner distance detection optoelectronics 6 become the same value, that is, the glass is relatively in a horizontal position.

[0024] In the horizontal direction, the position adjustment of the tray is carried out by a rectifying device. The glass horizontal correction device includes two rectifying devices, namely the first rectifying device 3 and the second rectifying device 4. Each rectifying device includes a rectifying column and a rectifying cylinder fixed on the rectifying column. The rectifying column of the first rectifying device 3 is fixed on the working base 1, and the output direction of the rectifying cylinder of this rectifying device is arranged parallel to the glass plane and the output end points to the side of the tray. The rectifying column of the second rectifying cylinder and the lifting motor of the photoelectric deviation corrector are both fixed on the mounting base 7. The output direction of the rectifying cylinder of the second rectifying device 4 is in the same plane as and perpendicular to the output direction of the rectifying cylinder of the first rectifying device 3. Through the action of the rectifying device, the tray can be pushed in place horizontally, facilitating the rectification of the tray with offset during loading.

[0025] Receiving the sensor signal, processing the signal and correspondingly controlling the action of the lifting motor are realized through the intelligent control system. The photoelectric sensor, the signal receiving sensor and the vacuum degree sensor are respectively signal-connected to the intelligent control system. After the signal of the photoelectric sensor is transmitted to the intelligent control system, the intelligent control system converts it into the action signal of the corresponding photoelectric deviation corrector 5 and transmits this action signal to the signal receiving sensor. During this process, the model of the vacuum degree sensor at the position of the vacuum chuck is also received by the intelligent control system, and an alarm indication is provided when the vacuum chuck is not horizontal, ensuring the horizontality of the glass sucked by the vacuum chuck during the working process and avoiding damage caused by dropping during the transfer process.

[0026] A glass horizontal correction device supporting a glass loading machine designed in this way, aiming at the problem of four-corner deformation of the tray, uses the glass to be loaded at the uppermost position as the reference for horizontal detection. When the uppermost glass is not horizontal, the height of the four corners is adjusted by the action of the photoelectric deviation corrector 5 below. After the uppermost glass is horizontal, the vacuum chuck is used to suck and load the material. Then, the operation is continued for the next piece of glass. Through the cooperation of the distance detection photoelectric sensor 6 and the photoelectric deviation corrector 5, each piece of glass to be loaded is adjusted to be horizontal before the loading operation, which can avoid the interference caused by the non-horizontal caused by the deformation of the tray body. At the same time, since the detection reference for loading is the glass at the uppermost position, different tray shapes and models can be compatible, effectively correcting the four-corner error and leveling different trays. The adjustment process is convenient and fast, the loading compatibility is high, the tray can be recycled multiple times, and the service life is long, achieving the effect of cost reduction and energy saving.

[0027] Inspired by the above ideal embodiments according to the present invention, through the above description, relevant staff can completely make various changes and modifications within the scope not deviating from the technical idea of this invention. The technical scope of this invention is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
