[0029] The embodiments of the present utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present utility model are described in detail below.

[0030] Reference below Figure 1-Figure 5 A glass substrate lifting mechanism 100 according to an embodiment of the present invention is described.

[0031] The glass substrate lifting mechanism 100 includes: a base assembly 10, a lifting assembly 20, a driving assembly 30 and a lifting assembly 40. The base assembly 10 is used to install the driving assembly 30 and the lifting assembly 40. The lifting assembly 20 is used to support the glass substrate. The lifting assembly 20 performs a lifting movement in the height direction under the action of the driving assembly 30 and the lifting assembly 40 to lift the glass substrate.

[0032] like Figure 1-Figure 3 As shown, the driving assembly 30 is disposed on the base assembly 10, and the driving assembly 30 is in transmission connection with the lifting assembly 20 and is used to drive the lifting assembly 20 to perform lifting motion. Specifically, the driving assembly 30 is disposed on the base assembly 10, and the driving assembly 30 is in transmission connection with the lifting assembly 20. Then, under the drive of the driving assembly 30, the lifting assembly 20 performs lifting motion, thereby performing a lifting operation on the glass substrate.

[0033] Combination Figure 1-Figure 4 As shown, the lifting assembly 40 includes: a plurality of connection seats 41, a plurality of lifting members 42 and a plurality of transmission members 43. The plurality of connection seats 41 are arranged at intervals on the base assembly 10. The upper ends of the lifting members 42 are fixedly connected to the jacking assembly 20 and the lower ends of the lifting members 42 pass through the connection seats 41. Any transmission member 43 is sandwiched between two adjacent connection seats 41 and is synchronously connected to the two adjacent lifting members 42. Specifically, the plurality of connection seats 41 are fixedly connected to the base assembly 10, the plurality of lifting members 42 correspond to the plurality of connection seats 41 one by one, the plurality of lifting members 42 extend in the height direction, the upper ends of the lifting members 42 are fixedly connected to the jacking assembly 20 so that the lifting members 42 move synchronously with the jacking assembly 20 in the height direction, and the lower ends of the lifting members 42 pass through the connection seats 41.

[0034] One end of the transmission member 43 is transmission-connected to the lifting member 42 in one of the connection seats 41, and the other end of the transmission member 43 is transmission-connected to the lifting member 42 in another adjacent connection seat 41. The transmission member 43 is kept horizontal due to the limit of the connection seat 41 on the transmission member 43. When the lifting member 42 moves along the height direction with the jacking assembly 20, the transmission member 43 makes the lifting member 42 transmission-connected to the transmission member 43 move synchronously, thereby ensuring the level of the jacking assembly 20 and preventing the glass substrate from sliding or breaking due to asynchronous lifting.

[0035] like Figure 1 As shown, a plurality of connection seats 41 are arranged at intervals from each other, and the connecting lines of the plurality of connection seats 41 form a closed polygon, so that various parts of the lifting assembly 20 can move up and down synchronously to keep the glass substrate level.

[0036] Thus, the driving assembly 30 drives the lifting assembly 20 to perform lifting motion, and the lifting member 42 moves with the lifting assembly 20. The transmission member 43 located between adjacent lifting members 42 enables each lifting member 42 to move synchronously, ensuring that the lifting assembly 20 horizontally supports the glass substrate, thereby preventing the glass substrate from sliding or breaking due to asynchronous lifting.

[0037] like Figure 1-Figure 4 As shown, the lifting member 42 is provided with a rack 421 and the rack 421 extends in the height direction, and gears are provided at both ends of the transmission member 43 and are respectively connected to two adjacent racks 421 in synchronous transmission. Specifically, the rack 421 extends in the height direction on the lifting member 42, and the transmission member 43 of the drive assembly 30 is perpendicular to the lifting member 42, and the transmission member 43 is arranged horizontally. Gears are provided at both ends of the transmission member 43, and the gears at both ends are respectively engaged with two adjacent racks 421, so that the two lifting members 42 move synchronously, ensuring that the lifting assembly 20 connected to the lifting member 42 horizontally supports the glass substrate, and preventing the lifting of various parts of the glass substrate from being asynchronous, causing sliding or fragmentation.

[0038] Furthermore, the lifting member 42 further includes: a connecting platform 422, which is arranged above the rack 421, and the connecting platform 422 is in contact with and fixedly connected to the lifting assembly 20. Specifically, the connecting platform 422 is located above the rack 421, that is, the lower end of the connecting platform 422 is fixedly connected to the rack 421, so that the rack 421 and the connecting platform 422 move up and down synchronously. The upper surface of the connecting platform 422 is flush with the upper surface of the driving assembly 30. The upper surface of the connecting platform 422 is fixedly connected to the lower end of the lifting assembly 20. When the driving assembly 30 drives the lifting assembly 20 to move in the height direction, the connecting platform 422 moves together with the lifting assembly 20, and then drives the rack 421 to move in the height direction, and the transmission member 43 connected between two adjacent racks 421 makes the adjacent racks 421 move synchronously, thereby ensuring that the lifting assembly 20 horizontally supports the glass substrate, and preventing the glass substrate from being raised and lowered asynchronously at various positions, causing sliding or fragmentation.

[0039] In some embodiments, a slideway is provided in the connection seat 41, and the rack 421 is provided on the slideway and moves up and down along the slideway under the drive of the driving assembly 30. Specifically, the slideway extends in the height direction, the rack 421 passes through the slideway and moves up and down along the slideway in the height direction, and the slideway limits the movement direction of the rack 421 to the height direction, and the two ends of the lifting member 42 are respectively inserted into the slideway and are transmission-connected with the racks 421 in the two connection seats 41, so that the two racks 421 move synchronously, thereby ensuring that the lifting assembly 20 horizontally supports the glass substrate, and preventing the glass substrate from being lifted and lowered asynchronously at various positions, causing sliding or fragmentation.

[0040] according to Figure 2-Figure 5As shown, the lifting assembly 20 includes: a first frame 21 and a plurality of mounting rods 22, the first frame 21 is fixedly connected to the lifting member 42, and the plurality of mounting rods 22 extend along the first direction and are spaced apart on the first frame 21 along the second direction. That is, the lower end of the first frame 21 is connected to the driving assembly 30, and the driving assembly 30 drives the first frame 21 to perform lifting and lowering motion along the height direction. The plurality of mounting rods 22 extend along the first direction, and the plurality of mounting rods 22 are spaced apart along the second direction, the first direction and the second direction are perpendicular, and the intervals between the plurality of mounting rods 22 can be adjusted to adjust the positions of the plurality of mounting rods 22 according to the size of the glass substrate, so as to ensure that the mounting rods 22 horizontally support the glass substrate.

[0041] Reference Figure 2-Figure 4 As shown, the lifting assembly 20 includes: a plurality of support members 23, the plurality of support members 23 are arranged at intervals from each other, the plurality of support members 23 are respectively arranged at intervals on a plurality of mounting rods 22, and the plurality of support members 23 are used to support the glass substrate. In other words, a plurality of support members 23 are arranged at intervals along the first direction on any mounting rod 22, the plurality of support members 23 are evenly spaced along the first direction, the lower end of the support member 23 is detachably connected to the mounting rod 22, so that the position of the support member 23 can be adjusted according to the size of the glass substrate, and the upper end of the support member 23 abuts against the glass substrate to support the glass substrate.

[0042] Furthermore, the support member 23 extends in the height direction, and the size of the support member 23 in the height direction is adjustable, so that the overall height of the lifting assembly 20 can be adjusted to adapt to various working conditions and expand the scope of application. The lengths of the multiple support members 23 are consistent so that the upper ends of the support members 23 are flush and horizontally support the glass substrate.

[0043] Furthermore, a contact piece is disposed at the upper end of the support piece 23 , and the contact piece may be made of an antistatic material. The contact piece is in direct contact with the lower end of the glass substrate, and the antistatic material may prevent static electricity from being generated between the support piece 23 and the glass substrate.

[0044] In some embodiments, the mounting rod 22 is provided with a groove, the groove extends along the first direction, the groove is a T-shaped groove and the groove is provided with an opening facing upward, and the support member 23 is connected to the groove. In other words, the glass substrate lifting mechanism 100 further includes: a fastening screw, the fastening screw includes a limiting portion and a connecting portion, the limiting portion is limitedly matched with the groove, the connecting portion passes through the opening and is fixedly connected to the lower end of the support member 23, and the connecting portion is detachably connected to the support member 23, so that the support member 23 is fixedly connected to different positions of the mounting rod 22 according to the size of the glass substrate.

[0045] like Figure 4As shown, the driving assembly 30 includes: a driving member 31 and a driving platform 32. The driving member 31 is arranged on the base assembly 10. The upper side of the driving platform 32 is fixedly connected to the lifting assembly 20. The driving member 31 and the driving platform 32 are in transmission connection. The driving member 31 drives the driving platform 32 to move so that the lifting assembly 20 performs a lifting movement. In other words, the upper side of the driving platform 32 is fixedly connected to the lower end of the first frame 21, and the upper surface of the driving platform 32 is flush with the upper surface of the connecting platform 422, so as to ensure the level of the first frame 21, thereby ensuring the horizontal support of the glass substrate. The driving platform 32 is located at the geometric center point of the lifting assembly 20 in the horizontal direction. The driving member 31 drives the driving platform 32 to perform lifting movement in the height direction, so that the lifting assembly 20 moves in the height direction, driving the lifting member 42 connected to the lifting assembly 20 to move up and down. Due to the setting of the transmission member 43, the displacement of each lifting member 42 in the height direction is consistent, ensuring that the upper surface of the lifting assembly 20 is flush, thereby horizontally supporting the glass substrate and ensuring that the glass substrate remains horizontal during the lifting and lowering process of the lifting assembly 20 (lifting is moving upward in the height direction, and lowering is moving downward in the height direction).

[0046] In some embodiments, the glass substrate lifting mechanism 100 further includes: a sensor, which is disposed on the lifting assembly 20, and is electrically connected to the driving assembly 30, and is used to detect whether there is a glass substrate on the lifting assembly 20. Specifically, the sensor can be disposed on the support 23, and the sensor can detect whether there is a glass substrate placed on the support 23. When the sensor detects that there is a glass substrate, the driving assembly 30 receives a signal from the sensor and controls the driving member 31 to drive the lifting rod assembly to lift or lower, thereby lifting or lowering the glass substrate.

[0047] Combination Figure 1-Figure 4 As shown, the base assembly 10 includes: a base 11 and an adjustment seat 12. The upper side of the base 11 is connected to a connection seat 41 and a driving assembly 30, and the lower side is connected to the adjustment seat 12. The adjustment seat 12 can adjust the height of the base 11. In other words, the lower side of the connection seat 41 is fixedly connected to the upper side of the base 11. The base 11 provides a mounting point for the driving assembly 30 and the lifting assembly 40. The connection seats 41 are arranged at intervals on the base 11, and the driving assembly 30 is fixed to the base 11. The upper side of the base 11 is connected to the adjustment seat 12. The height of the adjustment seat 12 is adjustable, thereby adjusting the height of the base 11, and expanding the application range of the glass substrate lifting mechanism 100.
