Description

Technical Field

[0001] This utility model relates to the field of photovoltaic glass coating production technology, specifically to an automatic height adjustment device for coating rollers in photovoltaic glass coating production. Background Technology

[0002] Solar photovoltaic (PV) cells are used to directly convert sunlight into electrical energy. In a solar PV cell, photovoltaic glass is the outermost layer on the front side, directly exposed to sunlight, utilizing its extremely high transmittance (>91.5%) to provide light energy to the cell. Photovoltaic glass coatings can effectively increase the solar transmittance of the glass surface (an increase of >2.0%), thereby improving the conversion efficiency and output power of the PV cell.

[0003] Current photovoltaic glass coating uses a roller coating process, where the coating solution is applied to the photovoltaic glass surface by the reverse rotation of the coating roller. The heights of the pressure roller and the coating roller are fixed. However, variations in the thickness of the photovoltaic glass (2.0mm thickness: 0.15mm tolerance) can cause the glass to fall below the coating roller, leading to constantly changing friction and related problems and defects. Coating operators manually adjust the heights of the pressure roller and coating roller based on experience, which is clearly untimely and requires repeated adjustments and confirmations. Utility Model Content

[0004] In order to solve the problems in the prior art, this utility model provides an automatic height adjustment device for coating rollers in photovoltaic glass coating production.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] An automatic height adjustment device for coating rollers in photovoltaic glass coating production includes a conveyor belt and a pressure roller and a coating roller located above the conveyor belt. With the conveying direction of the conveyor belt as the front-to-back direction, the coating roller is located behind the pressure roller. The photovoltaic glass is conveyed by the conveyor belt and passes under the pressure roller and the coating roller in sequence. The pressure roller is provided with pressure roller bearing seats at both ends, and the pressure roller bearing seats are installed on the slide rail frame to realize the sliding connection in the vertical direction.

[0007] A mounting bracket is provided above the pressure roller, and a clamping cylinder is provided on the mounting bracket. The piston end of the clamping cylinder is connected downward to the pressure roller bearing seat. At the same time, a height detection mechanism is also provided on the mounting bracket, which is used to detect the height of the pressure roller.

[0008] The coating roller is provided with coating roller bearing seats at both ends, and the coating roller bearing seats are installed on the coating roller lifting mechanism;

[0009] It also includes a controller, with the height detection mechanism connected to the signal input terminal of the controller, and the signal output terminal of the controller connected to the coating roller lifting mechanism.

[0010] Furthermore, the height detection mechanism includes several sets of dial indicators arranged along the axial direction of the pressure roller. The dial indicators are mounted on a mounting bracket, and the detection head of the dial indicator is in contact with the upper side of the pressure roller.

[0011] Furthermore, the slide rail frame includes two slide rails arranged opposite each other, both of which extend in the vertical direction; the pressure roller bearing seat is located between the two slide rails and slides in cooperation with the two slide rails.

[0012] Furthermore, the coating roller lifting mechanism includes a ball screw arranged in the vertical direction and a motor that is connected to the ball screw for transmission; a support threadedly connected to the ball screw is sleeved on the ball screw, and the support is fixedly connected to the coating roller bearing seat.

[0016] Furthermore, a photoelectric switch is provided at the entrance of the conveyor belt, and the photoelectric switch is connected to the signal input terminal of the controller.

[0017] The beneficial effects of this utility model are:

[0018] With this invention, when the photovoltaic glass reaches directly below the pressure roller, the pressing cylinder automatically presses down, causing the pressure roller to press the photovoltaic glass firmly. After the pressing cylinder presses down, the height detection mechanism detects changes in the thickness of the photovoltaic glass. If an abnormal thickness is detected, the height detection mechanism transmits the detected abnormal signal to the controller. After receiving the abnormal signal, the controller processes the signal and controls the coating roller lifting mechanism to start, automatically adjusting the height of the coating roller.

[0019] This utility model also includes a buzzer alarm. If the height detection mechanism detects that the thickness of the photovoltaic glass is abnormally large and exceeds the normal range, it will send an alarm signal to the buzzer alarm, causing the buzzer alarm to sound and flash, reminding the staff to handle the situation. It can monitor online in real time, is low-cost, simple and effective. Attached Figure Description

To better illustrate this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings. Detailed Implementation

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0029] like Figures 1 to 3 As shown, this embodiment provides an automatic height adjustment device for coating rollers in photovoltaic glass coating production, including a conveyor belt 5 and a pressure roller 1 and a coating roller 2 located above the conveyor belt 5. With the conveying direction of the conveyor belt as the front-to-back direction, the coating roller 2 is located behind the pressure roller 1; the photovoltaic glass 4 is conveyed by the conveyor belt 5 and passes under the pressure roller 4 and the coating roller 2 in sequence.

[0030] The pressure roller 1 has pressure roller bearings 63 at both ends, which are located in pressure roller bearing seats 61. The pressure roller bearing seats 61 are mounted on the slide rail frame 6. In this embodiment, the slide rail frame 6 includes two slide rails 62 arranged opposite each other, both of which extend in the vertical direction, and the upper ends of the two slide rails 62 are connected by a top plate. The pressure roller bearing seats 61 are located between the two slide rails and slide vertically with the two slide rails 62.

[0031] A mounting bracket 11 is provided above the pressure roller 1, and a clamping cylinder 14 is mounted on the mounting bracket 11. The piston end of the clamping cylinder 14 is connected downward to the pressure roller bearing seat. At the same time, a height detection mechanism is also provided on the mounting bracket, which is used to detect the height of the pressure roller 1.

[0032] In this embodiment, the height detection mechanism includes several sets of dial gauges 13 arranged along the axial direction of the pressure roller 1. The dial gauges 13 are mounted on the mounting bracket 11, and the detection head of the dial gauges 13 is in contact with the upper side of the pressure roller 1.

[0033] The coating roller 2 has coating roller bearing seats 21 at both ends. The coating roller bearing seats 21 are installed on the coating roller lifting mechanism, which can adjust the height of the coating roller 2.

[0034] In this embodiment, the coating roller lifting mechanism includes a ball screw 23 arranged in the vertical direction and a servo motor 24 that is connected to the ball screw 23 for transmission; a support 22 that is threadedly connected to the ball screw 23 is sleeved on the ball screw 23, and the support 22 is fixedly connected to the coating roller bearing seat 21; a lifting guide rail in the vertical direction is also provided in cooperation with the support 22, and the support and the lifting guide rail are slidably connected.

[0035] The servo motor 24 starts, which drives the ball screw 23 to rotate, thereby driving the support 22 to rise and fall, ensuring the automatic lifting effect of the coating roller.

[0036] It also includes a controller 15 and a buzzer alarm 12, both of which are mounted on the mounting bracket 11. The height detection mechanism is connected to the signal input terminal of the controller 15, and the signal output terminal of the controller 15 is connected to the coating roller lifting mechanism and the buzzer alarm 12, respectively.

[0037] A photoelectric switch 3 is installed at the entrance of the conveyor belt, and the photoelectric switch 3 is connected to the signal input terminal of the controller 15.

[0038] The working principle of this utility model is as follows:

[0039] During use, the photovoltaic glass 4 is placed on the conveyor belt 5 for transmission. First, the photovoltaic glass 4 is identified and detected by the photoelectric switch 3. The photoelectric switch 3 transmits the signal to the controller 15. The controller 15 sends a signal to the pressing cylinder 14. When the photovoltaic glass 4 reaches directly below the pressure roller 1, the pressing cylinder 14 automatically presses down, so that the pressure roller 1 presses the photovoltaic glass 4.

[0040] After the pressing cylinder 14 presses down, the dial indicator 13 will detect changes in the thickness of the photovoltaic glass 4. If an abnormal thickness of the photovoltaic glass 4 is detected, the dial indicator 13 will transmit the detected abnormal signal to the controller 15. After receiving the abnormal signal, the controller 15 processes the signal and then starts the servo motor 24. The servo motor 24 drives the ball screw 23 to rotate, which in turn drives the support 22 to rise and fall, ensuring the automatic lifting and lowering effect of the coating roller.

[0041] If the controller 15 processes the signal and finds that the thickness of the photovoltaic glass is abnormally beyond the normal range, it will send an alarm signal to the buzzer 12, causing the buzzer 12 to sound and flash, reminding the staff to handle the situation.
