Description

Technical Field

[0001] This application relates to the technical field of glass manufacturing. Specifically, it relates to a glass positioning mechanism and a glass edging machine. Background Art

[0002] When edging glass, the glass is usually placed on a grinding platform and fixed by negative pressure adsorption or pressing, and then edging is carried out. When grinding a group of glasses, in order to ensure the grinding accuracy, the glass needs to be positioned. There are two positioning methods. One is manual positioning, which has low positioning accuracy. The other is to use a detector to detect the position of the edging head in real time, which has a high cost.

[0003] In some existing devices (for example: the authorized announcement number is: CN 210103760U, and the name is a glass positioning device), a glass positioning device is provided. By fixedly arranging the guide rail, after the rotating shaft is installed and fixed to the cross beam and then cooperates with the guide rail, the driving device is connected to the rotating shaft and drives the rotating shaft to slide along the guide rail, so as to realize the displacement of the positioning device. At the same time, the mounting plate is used to arrange the driving cylinder, and the driving cylinder drives the positioning rod to offset in the up and down positions. The outer end of the positioning rod contacts the glass and applies pressure, so as to realize the positioning of the glass. When positioning the next group of glasses, in order to facilitate the placement of the glass, the positioning rod needs to be moved. After the glass is placed, the positioning rod moves slowly again to determine the positioning position. Therefore, this setting method results in low positioning efficiency.

[0025] Such as Figure 1 and Figure 2As shown, a glass positioning mechanism provided by an embodiment includes: a mounting structure 10, a positioning component 20, and a limiting component 30. The mounting structure 10 includes a first mounting plate 11 and a second mounting plate 12. The positioning component 20 is disposed on the first mounting plate 11, and the positioning component 20 includes a first positioning structure 21 and a second positioning structure 22. The limiting component 30 is located between the first mounting plate 11 and the second mounting plate 12. The limiting component 30 includes a first limiting structure 31 and a second limiting structure 32. The first limiting structure 31 cooperates with the first positioning structure 21, and the second limiting structure 32 cooperates with the second positioning structure 22.

[0026] Applying the technical solution of this embodiment, the glass positioning mechanism includes a mounting structure 10, a positioning component 20, and a limiting component 30. The mounting structure 10 includes a first mounting plate 11 and a second mounting plate 12. The positioning component 20 is disposed on the first mounting plate 11. The positioning component 20 includes a first positioning structure 21 and a second positioning structure 22. The limiting component 30 is located between the first mounting plate 11 and the second mounting plate 12. This setting makes the mechanism structure compact. The limiting component 30 includes a first limiting structure 31 and a second limiting structure 32. The first limiting structure 31 cooperates with the first positioning structure 21, and the second limiting structure 32 cooperates with the second positioning structure 22. According to the size of the glass, first adjust the first limiting structure 31 and the second limiting structure 32, and then adjust the first positioning structure 21 and the second positioning structure 22, so that the first positioning structure 21 abuts against the first limiting structure 31, and the second positioning structure 22 abuts against the second limiting structure 32. At this time, the positioning position can be determined. When positioning the next group of glasses, the first positioning structure 21 and the second positioning structure 22 can be quickly adjusted to the positioning position, and the first positioning structure 21 and the second positioning structure 22 abut against the outer wall of the glass, realizing the accurate positioning of the glass. The technical solution of this embodiment effectively solves the problem of low positioning efficiency in the prior art when positioning glass.

[0027] As Figure 1 shown, in some embodiments, the first limiting structure 31 includes a first mounting seat 311 and a first limiting bolt 312. The first mounting seat 311 is disposed on the first mounting plate 11. The first mounting seat 311 has a first threaded hole. The first limiting bolt 312 is inserted into the first threaded hole. The first limiting bolt 312 is in threaded cooperation with the first threaded hole. By rotating the first limiting bolt 312, the length of the first limiting bolt 312 exposed from the first threaded hole can be adjusted, and thus the corresponding adaptation to glasses of different sizes can be achieved.

[0028] As Figure 1As shown, in some embodiments, the first positioning structure 21 includes a first driving cylinder 211, a first connecting plate 212, and two groups of first positioning columns 213. The first driving cylinder 211 is disposed on the first mounting plate 11. The push rod of the first driving cylinder 211 is connected to the first end of the first connecting plate 212. The first driving cylinder 211 pushes the first connecting plate 212 to move along the first direction. The two groups of first positioning columns 213 are both connected to the second end of the first connecting plate 212. The first connecting plate 212 drives the two groups of first positioning columns 213 to move to position glass of different sizes. The first connecting plate 212 abuts against the first limit bolt 312 to limit the first connecting plate 212. It should be noted that the first mounting plate 11 is a rectangular plate. The first direction is the length direction of the first mounting plate 11, and the second direction is the width direction of the first mounting plate 11.

[0029] As Figure 1 shown, in some embodiments, the second limiting structure 32 includes a second mounting seat 321 and second limit bolts 322. The second mounting seat 321 has two second threaded holes. There are two groups of second limit bolts 322, and they are arranged in one-to-one correspondence with the two second threaded holes. The second limit bolts 322 are in threaded cooperation with the second threaded holes. By rotating the second limit bolts 322, the length of the second limit bolts 322 exposed from the second threaded holes can be adjusted, so as to adapt to glass of different sizes accordingly. The two groups of second limit bolts 322 are respectively located on both sides of the second mounting seat 321, so that the two groups of second limit bolts 322 can respectively limit the two groups of oppositely arranged second connecting plates 222.

[0030] As Figure 1 shown, in some embodiments, the second positioning structure 22 includes a second driving cylinder 221, two groups of second connecting plates 222, and four groups of second positioning columns 223. The second driving cylinder 221 is a two-way cylinder. The second driving cylinder 221 has two groups of push rods arranged in opposite directions. The two groups of push rods are respectively connected to the first ends of the two groups of second connecting plates 222 in one-to-one correspondence. The two groups of push rods push the two groups of second connecting plates 222 to move closer to or away from each other. Two groups of second positioning columns 223 are provided at the second end of each group of second connecting plates 222. The second positioning columns 223 move synchronously with the movement of the second connecting plates 222, and the positioning of glass of different sizes can be achieved.

[0031] As Figure 1 shown, in some embodiments, the second mounting seat 321 is disposed on the second driving cylinder 221. The two groups of second limit bolts 322 are respectively arranged in one-to-one correspondence with the two groups of second connecting plates 222. The two groups of second limit bolts 322 respectively abut against the two groups of second connecting plates 222 to limit the second connecting plates 222.

[0032] AsFigure 2 As shown, in some embodiments, the mounting structure 10 further includes four sets of lifting columns 14. The first ends of the four sets of lifting columns 14 are connected to the first mounting plate 11, and the second ends are connected to the second mounting plate 12. This arrangement provides a spacing distance between the first mounting plate 11 and the second mounting plate 12, forming a placement space for placing the positioning component 20 and the limiting component 30. At the same time, the lifting columns 14 drive the second mounting plate 12 and the glass stage 13 to lift, such that the height of the portions of the first positioning post 213 and the second positioning post 223 that protrude from the second mounting plate 12 is lower than the height of the glass stage 13, preventing interference with the edging machine during glass edging. The lifting columns 14 are electric push rods or cylinders.

[0033] It should be noted that the second mounting plate 12 is provided with a first long hole 121 along a first direction. The first positioning post 213 is movably inserted into the first long hole 121 and is located on one side in the width direction of the glass stage 13. The second mounting plate 12 is provided with a second long hole 122 along a second direction. The second positioning posts 223 are movably inserted into the second long hole 122, and the four sets of second positioning posts 223 are located on both sides in the length direction of the glass stage 13 in pairs. At the same time, this arrangement also facilitates the insertion of the glass from the other side in the width direction of the glass stage 13.

[0034] In some embodiments, the positioning component 20 further includes three displacement sensors and a controller. The three displacement sensors are respectively arranged corresponding to the first positioning structure 21 and the second positioning structure 22. The three displacement sensors are electrically connected to the controller, and both the three displacement sensors and the controller are arranged on the first mounting plate 11. The three displacement sensors can respectively detect the displacements of the first connecting plate 212 and the two second connecting plates 222 and transmit the detection signals to the controller, which is a PLC controller. The controller is electrically connected to both the first driving cylinder and the second driving cylinder, and the controller controls the first driving cylinder and the second driving cylinder according to the detection signals to further ensure the positioning accuracy.

[0035] As Figure 2 As shown, in some embodiments, the mounting structure 10 further includes a glass stage 13. The glass stage 13 is arranged on the second mounting plate 12. The glass stage 13 has a plurality of negative pressure adsorption holes, which can adsorb the glass on the glass stage 13. The glass stage 13 is communicated with an external negative pressure generating device for providing negative pressure.

[0036] The working process of the glass positioning mechanism is as follows: A set of glass is placed on the glass stage 13. At this time, the first positioning post 213 and the second positioning post 223 abut against the circumferential outer side of the glass. After positioning the glass to the accurate position, adjust the first limit bolt 312 and the second limit bolt 322 so that the first limit bolt 312 and the second limit bolt 322 respectively abut against the first connecting plate 212 and the second connecting plate 222. When positioning the next set of glass, for the convenience of placing the glass, the first positioning post 213 and the second positioning post 223 move. After the glass is placed on the glass stage 13, quickly move the first positioning post 213 and the second positioning post 223 again so that the first positioning post 213 and the second positioning post 223 respectively abut against the first limit bolt 312 and the second limit bolt 322. At this time, the positioning of the glass can be achieved. After the positioning is completed, the glass stage 13 firmly adsorbs the glass through negative pressure, and the lifting column 14 drives the second mounting plate 12 to lift and lower to prepare for edge grinding.

[0037] This embodiment also provides a glass edge grinding machine. The glass edge grinding machine includes a glass positioning mechanism. The glass edge grinding machine also includes a grinding table, a support frame, and an edge grinding head. The glass positioning mechanism is arranged on the grinding table. The glass positioning mechanism can achieve precise positioning of the glass placement position. At the same time, the glass stage 13 adsorbs the glass. The support frame is arranged on the grinding table, and the edge grinding head is arranged on the support frame and faces the glass positioning mechanism. The edge grinding head performs edge grinding on the glass.
