Description

Technical Field

[0001] The utility model mainly relates to the technical field of glass sheet production and processing, and specifically relates to a feeding mechanism for small glass sheets. Background Technique

[0002] With the development of technology and the Internet, electronic products have become essential communication and entertainment tools for people. Almost all electronic products have electronic display screens, and small glass sheets are important components of electronic display screens. In the traditional production and processing process of glass sheets, the process of the glass sheet entering the next process from one process includes manually feeding the glass sheet. Manual feeding requires workers to directly touch the glass sheet with their hands, which easily causes damage to the surface of the glass sheet and has a low feeding efficiency.

[0003] In the prior art, a telescopic cylinder is used to lower the height of the clamping jaw to grab the glass sheet above the substrate, and a pneumatic slide table and a rotary cylinder are used to drive the telescopic cylinder and the clamping jaw to move synchronously to complete the automatic feeding of the glass sheet. The surface of the glass sheet is not easily damaged and the feeding efficiency is relatively high. However, all three driving structures are arranged above the horizontal plane of the glass sheet bin, and a relatively large fixing part is required to connect and reinforce with the substrate, resulting in a heavy overall mechanism that is not easy to move and assemble. Moreover, the clamping jaw grabs the glass sheet from top to bottom, and the vision above the glass sheet is blocked during the grabbing process, and the staff cannot observe the grabbing situation in real time. Content of the Utility Model

[0004] Aiming at the above problems existing in the prior art, the purpose of the utility model is to provide a feeding mechanism for small glass sheets, in which the fixing part between the slide rail and the substrate is small, the overall weight is light, and the clamping jaw can horizontally move to grab the glass sheet.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: A feeding mechanism for small glass sheets, including a substrate, a slide rail is arranged on the substrate, a pneumatic slide table is arranged on the slide rail, a driving cylinder is arranged at one end of the slide rail, the driving cylinder is connected with the pneumatic slide table to drive the pneumatic slide table to slide along the slide rail, a rotary cylinder is arranged on the pneumatic slide table, the pneumatic slide table is located on the side wall of the slide rail, a connecting plate is arranged between the pneumatic slide table and the slide rail, a slider is arranged on the connecting plate and extends into the slide rail, a housing is arranged at the output end of the rotary cylinder, an electric clamping jaw is arranged at one end of the housing, and a telescopic electric cylinder is arranged at the other end. The electric clamping jaw is provided with a glass sheet bin on one side along the direction of the slide rail, and a detection device and a waste bin are arranged on the other side.

[0006] Preferably, a chute that fits the slider is formed on the top and bottom surfaces of the slide rail. Two identical chutes are formed on one side surface of the slide rail. The connecting plate is fixed on the pneumatic slide table. The number of sliders is two. Any one of the sliders is of an L-shaped structure, and the two ends of the L-shape are respectively clamped on the two adjacent chutes. A fixing member is provided between the slide rail and the substrate. Through the structural setting of the chute and the slider, the pneumatic slide table is slidably clamped on the slide rail along the direction of the chute.

[0007] Further, an adjusting frame is provided between the chutes on the top and bottom surfaces of the slide rail. The adjusting frame is fixedly connected to the inner side wall of the slide rail by threads. The sliding range of the slider in the slide rail can be limited by the thread connection with adjustable distance between the adjusting frame and the inner side wall of the slide rail.

[0008] Preferably, the housing is a hollow housing with both ends communicating. The output end of the telescopic electric cylinder is located inside the housing. The driving motor of the electric gripper is located inside the housing and is fixedly connected to the output end of the telescopic electric cylinder. The electric gripper is driven by the telescopic electric cylinder to perform telescopic movement independently.

[0009] Preferably, a rotating plate is provided between the housing and the rotary cylinder. The rotating plate is an L-shaped plate. The two outer walls perpendicular to each other of the rotating plate are respectively connected to the housing and the output end of the rotary cylinder. The rotating plate avoids direct contact between the housing and the output end of the rotary cylinder, thereby preventing damage to the electric gripper inside the housing.

[0010] Preferably, the glass sheet magazine is located on the substrate. A plurality of glass sheet slots are evenly distributed in a linear array on the glass sheet magazine. A glass sheet is provided on any one of the glass sheet slots. The glass sheet is perpendicular to the substrate. The glass sheets are vertically arranged on the substrate at equal intervals through the glass sheet magazine, so as to facilitate the electric gripper to grasp.

[0011] Preferably, an induction end is provided on the housing. The detection device is a CCD camera. The detection device detects the integrity of the surface of the glass sheet and the horizontal position of the induction end. The waste bin is fixed on one side of the detection device. The state of the glass sheet is detected by the detection device to select whether to perform further feeding and conveying, or to discard the material under the cooperation of the induction end.

[0012] Compared with the prior art, the present utility model has the following beneficial effects:

[0013] Through the structural setting between the pneumatic slide table and the slide rail, the electric gripper is horizontally arranged on one side of the glass sheet magazine to move and pick up materials in the horizontal direction. The distance from the substrate is relatively close, the requirement for the size of the fixing member between the slide rail and the substrate is low, the overall mechanism has a low height, a stable center of gravity and a low weight, is easy to install and move. During the material picking process, there is no obstruction at the connection between the electric gripper and the glass sheet, and it is easy to observe the clamping state;

[0014] The glass sheet in the jaw is detected through the induction end on the surface of the housing and the detection device on the substrate. According to the detection result, the jaw is loosened above the waste bin to discard the material, or the telescopic cylinder and the rotary cylinder connected to the electric jaw are activated to drive the electric jaw to move vertically and rotate, so that the electric jaw can load the material alone. The pneumatic slide table does not need to move. The structure has a high degree of automation and low power requirements for the telescopic cylinder and the rotary cylinder, and the working energy efficiency is relatively high.

[0025] The technical solution of the present invention will be further described below in conjunction with the drawings and through specific implementation manners.

[0026] An embodiment of the utility model provides a small glass sheet feeding mechanism, in which the fixing part between the slide rail and the substrate is small, the overall weight is light, and the clamping jaw can horizontally move to grasp the glass sheet.

[0027] As Figures 1 to 3 shown, a small glass sheet feeding mechanism includes a substrate 1, a slide rail 2 is arranged on the substrate 1, a pneumatic slide table 3 is arranged on the slide rail 2, a driving cylinder 8 is arranged at one end of the slide rail 2, the driving cylinder 8 is a mechanical rodless cylinder, and it does not have a piston rod outside. The piston device is built into the slide rail 2, and the externally loaded pneumatic slide table 3 is connected to the piston to drive the pneumatic slide table 3 to slide along the slide rail 2. A rotary cylinder 4 is arranged on the pneumatic slide table 3. The pneumatic slide table 3 is located on the side wall of the slide rail 2. A connecting plate 18 is arranged between the pneumatic slide table 3 and the slide rail 2. A slider 19 is arranged inside the slide rail 2 on the connecting plate 18. A housing 5 is arranged at the output end of the rotary cylinder 4. A rotating plate 15 is also arranged between the housing 5 and the rotary cylinder 4. The rotating plate 15 is an L-shaped plate. The two outer walls perpendicular to each other of the rotating plate 15 are respectively connected to the housing 5 and the output end of the rotary cylinder 4. An electric gripper 6 is arranged at one end of the housing 5, and a telescopic electric cylinder 16 is arranged at the other end. A glass sheet storage bin 7 is arranged on one side of the electric gripper 6 along the right direction of the slide rail 2, and a detection device 9 and a waste bin 10 are arranged in sequence on the left side.

[0028] A total of four chutes that fit the slider 19 are formed on the surface of the slide rail 2. Two chutes are distributed along the path of the slide rail 2 on the top and bottom surfaces, and two chutes are distributed along the path of the slide rail 2 on the inner side surface. The connecting plate 18 is fixed on the pneumatic slide table 3. The number of the sliders 19 is two. Any one of the sliders 19 is an L-shaped structure, and the two ends of the L-shape are respectively clamped on the two adjacent chutes. A fixing part 14 is fixedly connected between the slide rail 2 and the substrate 1. The height of the fixing part 14 just supports the connecting plate 18 above the substrate 1. An adjusting frame 11 is arranged between the chutes on the top and bottom surfaces of the slide rail 2. The adjusting frame 11 is an I-shaped structure. One outer wall of the adjusting frame 11 is fixedly connected to the inner side wall of the slide rail 2 by threads, and the distance between the adjusting frame 11 and the inner side wall of the slide rail 2 is adjusted by threads.

[0029] The housing 5 is a hollow housing with both ends communicating. The output end of the telescopic electric cylinder 16 is located inside the housing 5. The driving motor of the electric gripper 6 is located inside the housing 5 and is fixedly connected to the output end of the telescopic electric cylinder 16. The telescopic movement of the telescopic electric cylinder 16 drives the electric gripper 6 to move synchronously.

[0030] The glass sheet silo 7 is located on the substrate 1. A plurality of glass sheet slots 12 are evenly distributed in a linear array along the direction of the slide rail 2 on the glass sheet silo 7. A glass sheet 13 is arranged on any one of the glass sheet slots 12. The plurality of glass sheets 13 are equally spaced and perpendicular to the substrate 1. The electric gripper 6 slides along the slide rail 2 to accurately grip the glass sheet 13 at a fixed distance.

[0031] As Figure 4 shown, an induction end 17 is arranged on the outer wall of the housing 5. The detection device 9 is a CCD camera. The electric gripper 6 grips the glass sheet 13 and slides and rotates it until the glass sheet 13 is horizontal above the detection device 9. The detection device 9 detects the integrity of the surface of the glass sheet 13 and the horizontal position of the induction end 17. The waste bin 10 is fixed on the outer wall of the detection device 9 on the outer side facing away.

[0032] The implementation principle of the embodiment of the present application is as follows: When this feeding mechanism is used, first adjust the adjusting frame 11 by screwing according to the distribution of the glass sheets 13 in the glass sheet silo 7, so that the position of the adjusting frame 11 after adjustment is exactly the same as that of the rightmost glass sheet 13 in the glass sheet silo 7. At this time, the state of the mechanism is as Figure 1 shown; start the mechanism. Driven by the driving cylinder 8, the electric gripper 6 slides to the front of the glass sheet silo 7 along the slide rail 2, and moves equidistantly according to the distance between the glass sheet slots 12 to accurately grip the glass sheet 13 at the nearest end. After gripping, it slides to the left and rotates until the glass sheet 13 is exactly horizontal above the detection device 9. After the detection device 9 detects the glass sheet 13, it further slides to the left to above the waste bin 10. At this time, the state of the mechanism is as Figure 4 shown. Follow-up processes are carried out according to the detection results of the detection device 9. If the glass sheet 13 fails to pass the detection, the electric gripper 6 is directly released to make the glass sheet 13 fall into the waste bin 10. If it passes the detection, the rotary cylinder 4 drives the electric gripper 6 to further turn until the glass sheet 13 is located above the telescopic electric cylinder 16, and the telescopic electric cylinder 16 drives the electric gripper 6 to move upward to lift the glass sheet 13 to the next process; repeat the above process until all the glass sheets 13 in the glass sheet silo 7 are completely transported. At this time, the slider 19 abuts against the adjusting frame 11 and cannot slide, and the mechanism stops working.
