Description

Technical Field

[0001] This utility model belongs to the field of glass size detection technology, and relates to a carrier glass size detection and positioning device. Background Technology

[0002] A carrier glass size detection and positioning device is an automated equipment applied in glass production, processing and quality inspection. Its core function is to achieve precise positioning of carrier glass through mechanical, pneumatic and optical technologies, and to cooperate with the detection system to complete the measurement and judgment of glass dimensions (such as length, width, diagonal, aperture, contour, etc.).

[0003] For example, patent (CN218895747U) discloses a positioning fixture for glass size detection, including a worktable, a fixed frame fixedly installed on the top of the worktable, a first sliding groove opened inside the fixed frame, a positioning slider disposed inside the fixed frame, the positioning slider being slidably connected to the first sliding groove, a motor disposed on one side of the fixed frame, a lead screw fixedly connected to the output end of the motor, the lead screw passing through the positioning slider, and the lead screw being threadedly connected to the positioning slider; this positioning fixture can fix a glass sample between a positioning baffle and a fixed baffle without deviation, and can detect the size of the glass sample by the distance between a laser size measuring instrument and a distance measuring plate.

[0004] However, in actual use, this positioning fixture requires the glass to be positioned on two sets of suction cups first. Then, a baffle on one side is used to push the glass to a fixed baffle on the other side. However, the device does not have a bidirectional pre-positioning mechanism for the glass before it is placed on the suction cups. This may cause the glass to deviate at an angle after being positioned with the suction cups, which may result in the glass not being able to effectively fit with the baffle and the fixed baffle, leading to measurement errors. In addition, the distance between the two sets of suction cups is fixed. When dealing with glass of different sizes, the two sets of suction cups cannot adjust the layout, which may result in poor glass positioning stability, thus requiring improvement. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a carrier glass size detection and positioning device.

[0006] The present invention discloses a carrier glass size detection and positioning device, comprising a detection platform, a support plate installed below the detection platform, an mounting plate installed inside the detection platform, a limiting groove provided in the mounting plate, slider A and slider B slidably installed in the limiting groove, a guide rod installed below slider A and slider B, a vertical plate A installed on slider A, a connecting rod installed above slider A and slider B, a suction cup installed above the connecting rod, slider B being connected to the vertical plate B via a pre-pressing mechanism, a rotating plate rotatably installed inside the detection platform, a guide groove provided in the rotating plate, a worm gear installed below the rotating plate, a worm engaging on one side of the worm gear, and a motor installed on the support plate.

[0007] The preload mechanism includes a slide rod, a side plate, a vertical plate B, and a spring. The slide rod is slidably disposed inside the slider B. The side plate is installed at one end of the slide rod, the vertical plate B is installed at the other end of the slide rod, and the spring is sleeved on the slide rod.

[0008] The worm gear is installed at the output end of the motor, and the guide rod is set in the guide groove.

[0009] Indicator blocks are installed on both sides of the vertical plate A and the vertical plate B, and scale grooves are provided on the mounting plate.

[0010] One end of the spring is connected to the side plate, and the other end of the spring is mounted on the slider B. The spring drives the vertical plate B to tend to move closer to the slider B.

[0011] An electric push rod is installed inside the mounting plate, and a bearing plate is installed at the output end of the electric push rod. Ball bearings are rolled on the bearing plate.

[0012] The number of electric push rods and bearing plates are four sets, and they are symmetrically distributed on the mounting plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] I. In this utility model, the synchronous displacement of multiple suction cups along the limiting groove is achieved by motor drive, thereby allowing the suction cup layout to be quickly adjusted according to the size characteristics of glass of different specifications, effectively improving the applicability of the equipment. At the same time, through the pre-pressing mechanism of slider B, the combined effect of spring buffer and slide rod guidance is used to achieve bidirectional synchronous pre-positioning of the length and width of the glass plate with different side lengths. With the help of the scale groove and indicator block on the detection table, the visual measurement of the length and width of the glass can be completed first, without the need for special measuring tools.

[0015] II. In this utility model, by setting an electric push rod, a support plate, and ball bearings, it is convenient for operators to quickly adjust the glass position to the detection position before glass inspection, avoiding angular deviation of the glass placement. The ball bearings evenly distributed on the support plate replace sliding friction with rolling friction, greatly reducing the resistance to glass movement. The electric push rod drives the support plate to descend smoothly in the vertical direction, so that the glass fits with the suction cup below, significantly improving the efficiency and positioning accuracy of the inspection process.

[0022] Example

[0023] like Figures 1-5 As shown, the system includes a testing platform 1, a support plate 2 installed below the testing platform 1, an installation plate 3 installed inside the testing platform 1, a limit groove 4 provided in the installation plate 3, sliders A5 and B6 slidably installed in the limit groove 4, a guide rod 7 installed below sliders A5 and B6, a vertical plate A8 installed on slider A5, a connecting rod 9 installed above sliders A5 and B6, a suction cup 10 installed above the connecting rod 9, slider B6 connected to a vertical plate B13 via a pre-pressing mechanism, a rotating plate 17 rotatably installed inside the testing platform 1, a guide groove 18 provided in the rotating plate 17, a worm gear 19 installed below the rotating plate 17, a worm 20 meshing on one side of the worm gear 19, and a motor 21 installed on the support plate 2.

[0024] The pre-compression mechanism includes a slide rod 11, a side plate 12, a vertical plate B13, and a spring 14. The slide rod 11 is slidably mounted inside the slider B6. The side plate 12 is mounted on one end of the slide rod 11, and the vertical plate B13 is mounted on the other end of the slide rod 11. The spring 14 is sleeved on the slide rod 11. Through the pre-compression mechanism of the slider B6, the combined effect of the spring 14's buffering and the slide rod 11's guiding action enables bidirectional synchronous pre-positioning of the length and width of glass plates with different side lengths.

[0025] The worm gear 20 is installed at the output end of the motor 21, and the guide rod 7 is set in the guide groove 18. When the motor 21 is started, it drives the worm gear 20 to rotate, which in turn drives the rotating plate 17 to rotate due to the meshing action between the worm gear 19 and the worm wheel 19. Under the mechanical coupling action between the guide groove 18 and the guide rod 7, each guide rod 7 and the upper sliders A5 and B6 are forced to slide inward synchronously along the limiting groove 4.

[0026] Indicator blocks 15 are installed on both sides of vertical plates A8 and B13, and scale grooves 16 are provided on the mounting plate 3. During the pre-positioning process, the length and width dimensions of the glass can be recorded in advance with the help of the indicator blocks 15 and scale grooves 16.

[0027] One end of spring 14 is connected to side plate 12, and the other end of spring 14 is mounted on slider B6. Spring 14 drives vertical plate B13 to tend to move closer to slider B6. After the positioning work is completed, spring 14 can quickly drive vertical plate A8 to achieve a reset effect.

[0028] An electric push rod 22 is installed inside the mounting plate 3. A support plate 23 is installed at the output end of the electric push rod 22. Ball bearings 24 are rolled on the support plate 23. When the electric push rod 22 is activated, it drives the support plate 23 to rise. Then, the glass plate can be placed on the support plate 23. At this time, the ball bearings 24 on the support plate 23 can replace sliding friction through rolling friction.

[0029] There are four sets of electric push rods 22 and four sets of support plates 23, which are symmetrically distributed on the mounting plate 3. This effectively improves the stability of the glass sliding above and prevents the glass from falling and causing economic losses.

[0030] Working principle: During operation, the electric push rod 22 is first activated, causing the support plate 23 to rise. Then, the glass plate can be placed on the support plate 23. At this time, the ball bearings 24 on the support plate 23 can replace sliding friction with rolling friction, significantly reducing the resistance to glass movement. This allows the operator to quickly adjust the glass position to the detection position. During this process, the long side of the glass is kept perpendicular to the vertical plate B13, and the short side is kept perpendicular to the vertical plate A8. Then, the motor 21 is activated, driving the worm gear 20 to rotate. The meshing action with the worm wheel 19 drives the rotating plate 17 to rotate, thereby causing the guide groove 18 to adjust its position. Under the mechanical coupling between the guide groove 18 and the guide rod 7, each guide rod 7 and the upper sliders A5 and B6 are forced to move synchronously along... When the limiting groove 4 slides inward, the slider B6 will cause the vertical plate B13 to first contact the long side of the glass. At this time, the slider B6 will continue to slide along the limiting groove 4. Since the glass blocks the vertical plate B13, the slider B6 will slide along the sliding rod 11 and simultaneously compress the spring 14 until the vertical plate A8 is attached to the short side of the glass. This not only allows for the centering and pre-positioning of the glass, but also allows the indicator block 15 and the scale groove 16 to record the length and width dimensions of the glass first. After the calibration is completed, the electric push rod 22 is activated and the carrier plate 23 is lowered. At the same time, the upper carrier glass is lowered until the glass is attached to the suction cup 10 below, thus achieving the positioning of the carrier glass. This allows for the measurement of other dimensions and avoids errors caused by glass movement during the measurement process.
