Description

Technical Field

[0001] The utility model relates to the technical field of tempered glass production, in particular to a fragment detection device for tempered glass production. Background Art

[0002] Tempered glass is a kind of prestressed glass. In order to improve the strength of glass, compressive stress is usually formed on the surface of glass by chemical or physical methods. Tempered glass has the characteristics of high strength, good safety, high temperature resistance, good light transmittance, easy cleaning and processing, so it is widely used in construction, home, automobile and other fields.

[0003] During the production process of tempered glass, due to factors such as raw materials, processes or equipment, damage or cracks may occur in the tempered glass plate, resulting in local fragments. These fragments will affect the final quality of the product. Manual detection is difficult and easily affected by the detection environment and manual experience. The detection efficiency is low and the labor intensity is high. To this end, we propose a fragment detection device for tempered glass production. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the existing defects and provide a broken glass detection device for tempered glass production, which can greatly improve the detection efficiency through automatic detection, reduce the labor intensity of the staff, thereby improving the work efficiency, and can effectively solve the problems in the background technology.

[0006] As a preferred technical solution of the utility model, the driving mechanism includes a reduction motor arranged on the side surface of the base plate, the output shaft of the reduction motor passes through the slide groove and is connected to the driving screw through a coupling, and the driving screw is threadedly connected to the screw hole opened on the side surface of the sliding seat.

[0007] As a preferred technical solution of the utility model, screw holes are provided on the upper surfaces of both ends of the sliding seat, and fixing bolts for fixing the sliding frame are threadedly connected to the inner threads of the screw holes.

[0008] As a preferred technical solution of the utility model, two wheel frames are symmetrically installed on both sides of the side surface of the mounting seat, rollers are rotatably arranged on the wheel frames, and a wheel groove matching the side edge of the tempered glass is opened in the middle of the outer surface of the roller.

[0009] As a preferred technical solution of the utility model, the end surface of the sliding frame is provided with a mounting groove, the mounting seat is slidably arranged in the mounting groove, and a spring is arranged between the inner surface of the mounting groove and the mounting seat.

[0010] As a preferred technical solution of the utility model, two mounting plates are symmetrically arranged on the two side surfaces of the base plate, a ranging sensor is arranged on the side surface of the mounting plate facing the sliding seat, and a positioning plate corresponding to the ranging sensor is installed on the side surface of the sliding seat facing the mounting plate.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows: the produced tempered glass is conveyed to the top of the bottom plate by the external conveying roller, and is detected by the infrared signal transmitter and the infrared signal receiver on both sides of the tempered glass, and the infrared signal transmitter and the infrared signal receiver are arranged on the same horizontal straight line. When there are no broken pieces or cracks in the tempered glass, the infrared signal emitted by the infrared signal transmitter is transmitted straight through the tempered glass to the infrared signal receiver and received by it; when there are broken pieces or cracks in the tempered glass, the infrared signal emitted by the infrared signal transmitter will be refracted, so that the infrared signal receiver cannot receive its signal. The external controller determines the quality of the tempered glass and the alarm prompts the staff to manually inspect the tempered glass. Automatic inspection can greatly improve the inspection efficiency and reduce the labor intensity of the staff, thereby improving the work efficiency. The driving mechanism drives the sliding seat and the sliding frame to move, thereby driving the mounting seat and the infrared signal transmitter and the infrared signal receiver to move along the length direction of the tempered glass. When broken pieces or cracks are detected in the tempered glass, the conveying roller is stopped, and the infrared signal transmitter and the infrared signal receiver are moved along the tempered glass for re-inspection, thereby improving the accuracy of the inspection result.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-5 The utility model provides a technical solution: a broken fragment detection device for tempered glass production, comprising a bottom plate 1 arranged under a tempered glass conveying roller, a side surface of the bottom plate 1 is provided with a slide groove 2 penetrating both sides of the bottom plate 1, a sliding seat 3 is slidably arranged in the slide groove 2, and a driving mechanism for driving the sliding seat 3 to slide in the slide groove 2 is arranged on the bottom plate 1, both end side surfaces of the sliding seat 3 are provided with grooves, an L-shaped sliding frame 7 is slidably arranged in the groove, and mounting seats 8 are arranged on opposite sides of the two sliding frames 7, one of the mounting seats 8 is provided with an infrared signal transmitter 9 on the side facing the middle of the bottom plate 1, and the other mounting seat 8 is provided with an infrared signal receiver 10 matching the infrared signal transmitter 9 on the side facing the middle of the bottom plate 1, and the infrared signal transmitter 9 and the infrared signal receiver 10 are arranged on the same horizontal straight line. In the production process, the tempered glass is smoothly conveyed to the top of the bottom plate 1 by the external conveying roller, and when the produced tempered glass passes before the infrared signal transmitter 9 and the infrared signal receiver 10, the infrared signal transmitter 9 will send an infrared signal. If there are no broken pieces, cracks or other defects inside the tempered glass, the infrared signal will be transmitted in a straight line, directly penetrate the glass and be received by the infrared signal receiver 10 on the opposite side. This unobstructed signal transmission indicates that the quality of the glass is intact.

[0020] If there are broken pieces, cracks or other discontinuous areas inside the tempered glass, the propagation path of the infrared signal will be affected. These defects will cause the infrared signal to be refracted or scattered, making it impossible for the signal that should have been transmitted in a straight line to be received normally by the receiver. Once the infrared signal receiver 10 is unable to receive the signal from the transmitter, an external controller such as a PLC controller or a single-chip microcomputer will immediately make a judgment and trigger an alarm such as a speaker, a buzzer or a flashing light to remind the staff. The staff will immediately notice it and can perform manual quality inspection on the corresponding tempered glass. In this way, problematic tempered glass can be quickly identified, thereby avoiding the low efficiency and easy missed inspection problems of traditional manual visual inspection.

[0021] This automatic detection method not only greatly improves the detection efficiency and reduces the labor intensity of the staff, but also ensures the quality of tempered glass and improves the overall work efficiency. In modern and automated production lines, this infrared signal detection system has become an indispensable part, providing a strong quality guarantee for the production of tempered glass.

[0022] The driving mechanism drives the sliding seat 3 and the sliding frame 7, the mounting seat 8, the infrared signal transmitter 9 and the infrared signal receiver 10 to move accurately and stably along the length direction of the tempered glass; in the production of tempered glass, the infrared signal transmitter 9 and the infrared signal receiver 10 are key devices for detecting defects such as broken pieces and cracks. They transmit and receive infrared signals and analyze the changes in the signals to determine whether there are abnormalities inside the glass.

[0023] Once the infrared signal transmitter 9 and the infrared signal receiver 10 find defects such as broken pieces or cracks inside the tempered glass during the inspection process, they will quickly feed back this information to the external controller. After receiving the signal, the controller will immediately respond and stop the operation of the conveyor roller. At this time, the tempered glass on the production line will temporarily stop moving forward to prepare for subsequent re-inspection.

[0024] Then the driving mechanism is started, and the mounting seat 8, the infrared signal transmitter 9 and the infrared signal receiver 10 are driven to re-check along the length direction of the tempered glass through the sliding seat 3 and the sliding frame 7. During this process, the equipment will conduct a second inspection on the abnormal area detected before to ensure the accuracy of the inspection results.

[0025] This re-inspection mechanism can not only effectively avoid missed inspections and false inspections, but also significantly improve the accuracy of the inspection results. This is of great significance for ensuring the quality of tempered glass, improving product competitiveness, and safeguarding the interests of consumers. At the same time, this automated and intelligent inspection method also reduces the need for manual intervention and improves production efficiency.

[0026] One of the preferred technical solutions for the driving mechanism includes a reduction motor 4 arranged on the side surface of the base plate 1, the output shaft of the reduction motor 4 penetrates into the slide groove 2 and is connected to the driving screw 5 through a coupling, the driving screw 5 is threadedly connected to the screw hole opened on the side surface of the sliding seat 3, and the driving screw 5 is driven by the reduction motor 4 to rotate, so that the sliding seat 3 slides in the slide groove 2, thereby driving the infrared signal transmitter 9 and the infrared signal receiver 10 to re-inspect along the length direction of the tempered glass. The structure is simple and easy to maintain and operate.

[0027] According to a preferred technical solution, screw holes are provided on the upper surfaces of both ends of the sliding seat 3, and fixing bolts 6 for fixing the sliding frame 7 are threadedly connected to the screw holes. The sliding frame 7 can slide back and forth in the groove on the sliding seat 3, so as to be adjusted according to tempered glass of different widths to be suitable for the detection of tempered glass of different specifications, which greatly improves the universality. After being adjusted into place, it is fixed by the fixing bolts 6 to ensure the stability of the detection process.

[0028] An optional technical solution is that two wheel frames 11 are symmetrically installed on both sides of the side surface of the mounting seat 8, and rollers 12 are rotatably arranged on the wheel frames 11. A wheel groove 13 matching the side edge of the tempered glass is opened in the middle of the outer surface of the roller 12. When the tempered glass is being conveyed or the mounting seat 8 is moved by the driving mechanism, the roller 12 is stuck on the edges of both sides of the tempered glass through the wheel groove 13, thereby ensuring that the infrared signal transmitter 9 and the infrared signal receiver 10 are flush with the tempered glass, thereby ensuring the accuracy of the detection result.

[0029] Further optionally, a mounting groove 14 is provided on the end face of the sliding frame 7, and the mounting seat 8 is slidably arranged in the mounting groove, and a spring 15 is arranged between the inner surface of the mounting groove 14 and the mounting seat 8. The mounting seat 8 can be pressed against the tempered glass under the pressure of the spring 15, so that the roller 12 is pressed against the outside of the tempered glass, further ensuring the stability of the detection process.

[0030] The number of infrared signal transmitters 9 and infrared signal receivers 10 is no less than three groups, and no less than three groups of infrared signal transmitters 9 and infrared signal receivers 10 are evenly arranged from top to bottom, which can detect different thickness positions of tempered glass. It is also suitable for fragment detection of tempered glass of different thicknesses, further improving universality.

[0031] According to a preferred technical solution, two mounting plates 17 are symmetrically arranged on both side surfaces of the bottom plate 1, and a distance sensor 18 is arranged on one side surface of the mounting plate 17 facing the sliding seat 3. A positioning plate 16 corresponding to the distance sensor 18 is installed on one side surface of the sliding seat 3 facing the mounting plate 17. The distance sensor 18 can detect the moving distance of the sliding seat 3 through the positioning plate 16, and transmit the detected distance change value to an external controller, and the external controller analyzes and compares the distance values ​​detected by the two distance sensors 18, so as to determine whether the sliding seat 3 is offset during the movement and whether the connection line between the infrared signal transmitter 9 and the infrared signal receiver 10 is perpendicular to the side of the tempered glass. When it is determined that it is not perpendicular, the staff can be reminded to make adjustments in time through an alarm to ensure the accuracy of the detection result.

[0032] The controller used in the present application is preferably a Mitsubishi FX2N series PLC controller, and the methods of controlling the reduction motor 4, the infrared signal transmitter 9, the infrared signal receiver 10, the distance sensor 18, the driver of the external conveying roller and the alarm, etc. are all commonly used methods in the prior art; the PLC controller, the reduction motor 4, the infrared signal transmitter 9, the infrared signal receiver 10, the distance sensor 18, the driver of the external conveying roller and the alarm, etc. used in the present application are all common electronic components on the market, and their specific structures, working principles and circuit connections, etc. are all well-known technologies and will not be described in detail here.

Although the embodiments of the present utility model have been shown and described, it is understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present utility model, and the scope of the present utility model is defined by the attached claims and their equivalents.
