Description

Technical Field

[0001] The utility model relates to the technical field of glass, in particular to an automatic glass loading and unloading device for a glass strength testing machine. Background Art

[0002] At present, the output of the photovoltaic glass industry has increased sharply. In order to monitor product quality, a large number of glass strength tests need to be carried out using strength detection equipment such as four-point bending testing machines, mechanical load testing machines, hail testing machines, etc. When conducting glass strength tests, glass loading and unloading operations are required. The traditional method is to manually carry the glass and place it on the test platform. Since the glass test platforms of general detection equipment are relatively high (generally higher than 1.5 m) and the tested glass is mainly semi-tempered thin glass with a thickness of 2.0 mm or less, there are potential safety hazards of glass breakage and injury during manual handling. Moreover, the photovoltaic glass has a large size (the mainstream size specification is above 2272 mm * 1128 mm * 2.0 mm), requiring two people to carry it, and the manual handling efficiency is low due to frequent strength test experiments.

[0003] In the prior art, there are also glass loading devices, most of which are not suitable for stably placing the test glass on the test platform and cannot meet the requirements of both loading and unloading at the same time. For example, a glass loading device disclosed in Chinese Patent CN215710054U has: a rotating assembly, a suction cup swing arm assembly, and a conveyor line; it can adsorb and rotate the glass and convey the glass for loading, with high working efficiency. During the swinging process of the glass adsorption assembly, the angle of the adsorption assembly can be changed to meet the usage requirements of glass with different placement angles; however, it cannot stably place the test glass on the test platform.

[0028] The suction cup is fixed to the lower end of the telescopic rod through a suction cup holder. A distance sensor is arranged on the suction cup holder. By sensing the distance between the suction cup and the glass through the distance sensor, the control is simple. Furthermore, a handrail 11 is arranged on one side of the chassis where the swing support link assembly is located, and a controller 12 is arranged on the handrail.

[0029] A preferred specific embodiment of the present utility model is:

[0030] The automatic glass loading and unloading device of the glass strength testing machine includes a controller, a chassis (frame, steering wheels *4, brackets *4), a suction cup group (suction cups *8, spring telescopic rods *8, suction cup holders, distance sensors), swing arms *4, a motor, a vacuum pump, etc.

[0031] The controller has a built-in program and can control the operation of the instrument by selecting the upper and lower sheets and setting parameters such as the number of suction cups used, the moving speed, the lowering height of the suction cups, and the number of stacked sheets; it is also possible to determine whether to set the controller according to the specific usage situation.

[0032] There are 4 steering wheels and 4 brackets under the chassis. The steering wheels are used to move the instrument, and the brackets are used to fix the instrument. When moving the instrument, the brackets need to be retracted, and when fixing the instrument, the brackets are screwed down again;

[0033] The suction cup group consists of a suction cup holder, suction cups, spring telescopic rods, positioning sliders, and distance sensors. The suction cup holder is composed of 2 mounting seats, 2 main slide rails, 4 secondary slide rails, and 16 positioning sliders. The two main slide rails are placed in parallel and fixed at both ends on the two mounting seats. The secondary slide rails are connected to the main slide rails through the positioning sliders. The secondary slide rails are perpendicular to the main slide rails and can move along the main slide rails depending on the positioning sliders; the spring telescopic rods are connected to the secondary slide rails through the positioning sliders under the slide rails and can move along the secondary slide rails depending on the positioning sliders. One spring telescopic rod is connected to each end of each secondary slide rail, for a total of 8 spring telescopic rods; one suction cup is fixed at the bottom of each spring telescopic rod, for a total of 8 suction cups. The distance sensor is fixed downward in the middle of the suction cup holder, and the bottom of the sensor is slightly higher than the bottom of the suction cups.

[0034] The two front swing arms are parallel to each other, one end is connected to the motor, and the other end is connected to the mounting seat. One end of the two rear swing arms is connected to the base, and the other end is connected to another mounting seat. The motor drives the front swing arms to rotate, thereby driving the movement of the suction cup group and the rotation of the rear swing arms.

[0035] The vacuum pump is connected to the 8 suction cups through an air pipe to provide suction for the suction cups.

[0036] The specific process flow is as follows:

[0037] Preparation work:

[0038] Move the device of this patent beside the glass strength testing machine, adjust the distance between the machine and the testing machine to ensure that the position of the suction cups corresponds to the position of the testing platform of the testing machine when the suction cups fall, and fix the brackets;

[0039] Place the tray on the other side of the machine to ensure that the position of the suction cups corresponds to the position of the glass on the tray when the suction cups fall; 3. Adjust the position of the suction cups according to the position of the testing platform of the testing machine and the glass pattern;

[0040] Start working:

[0041] Connect the power cord, turn on the main power, motor power, compressor power, and vacuum pump power of the instrument, select the upper and lower sheets, and input the number of suction cups used, the running speed, the lowering height of the suction cups, and the number of stacked sheets;

[0042] Test the upper sheet:

[0043] The motor rotates forward, driving the steering rod to rotate clockwise. The suction cup rotates to the glass surface on the tray (a spring is built into the suction cup telescopic rod to prevent the glass from being broken). After the distance sensor senses that the distance to the glass reaches the initially set distance, it stops moving (the sensor is shorter than the suction cup, and the sensor will only send a signal to stop moving when the suction cup telescopic rod shortens to a certain extent); the suction cup is activated to adsorb the glass;

[0044] The motor rotates in reverse, driving the steering rod to rotate counterclockwise. The suction cup telescopic rod returns to its original length, and then the suction cup drives the glass to rotate above the production line;

[0045] After reaching the set height, air enters the suction cup, and the glass falls onto the test bench;

[0046] After the test is completed, the glass is unloaded:

[0047] The motor rotates in reverse, driving the steering rod to rotate counterclockwise. The suction cup rotates to the glass surface on the test bench. After the distance sensor senses that the distance to the glass reaches the initially set distance, it stops moving (the sensor is shorter than the suction cup, and the sensor will only send a signal to stop moving when the suction cup telescopic rod shortens to a certain extent); the suction cup is activated to adsorb the glass;

[0048] The motor rotates forward, driving the steering rod to rotate clockwise. The suction cup telescopic rod returns to its original length, and then the suction cup drives the glass to rotate above the tray;

[0049] After reaching the set height, air enters the suction cup, and the glass falls onto the tray.

[0050] This device has the following advantages: 1) Simple operation, saving manpower; 2) Automated mechanical work, high efficiency; 3) This device can be flexibly moved to adapt to different strength testing equipment and be used in conjunction with it, with simple operation; 4) Low safety hazards.

[0051] The above is only an illustration of the preferred embodiments of the present invention. The above technical features can be arbitrarily combined to form multiple embodiment schemes of the present invention.

Obviously, the specific implementation of the present invention is not limited by the above methods. As long as various non-substantive improvements are made by adopting the concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
