Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of glass transportation, and particularly relates to a wafer glass alignment device. BACKGROUND

[0002] Glass plates often need to be transported by a glass plate transportation device in the production process. For example, a glass substrate conveying device and production system disclosed in Chinese patent CN221026327U can realize bidirectional transmission of glass substrates, thereby improving the transportation efficiency of glass plates.

[0003] However, when the glass plates are wafer glasses with notches, the notches on each wafer glass need to be aligned after transportation, so as to facilitate subsequent automated processing of the glass plates. The existing alignment method for the notches on each wafer glass is to align the notches by manual arrangement. This alignment method is time-consuming and labor-intensive, and reduces the subsequent wafer glass processing efficiency. CONTENT OF THE UTILITY MODEL

[0004] One technical problem to be solved by the present disclosure is that it is time-consuming and labor-intensive to align the notches on the wafer glasses.

[0005] To solve the above technical problem, the present disclosure provides a wafer glass alignment device for aligning wafer glasses with notches, which comprises:

[0006] a support frame, a plurality of mounting slots are formed in the support frame and are arranged at intervals along a first direction, and the mounting slots are used for mounting the wafer glasses; and

[0007] a rotating shaft, the rotating shaft is arranged at the bottom of the mounting slot and extends along the first direction, and the rotating shaft can rotate along the axis direction thereof;

[0008] The rotating shaft is rotated to drive the wafer glasses to rotate, and the notches of each wafer glass are clamped on the rotating shaft under the action of gravity.

[0009] In some embodiments, the diameter of the rotating shaft is smaller than the maximum width of the entrance end of the notch on the wafer glass.

[0010] In some embodiments, the wafer glass alignment device is further provided with a monitoring assembly, the monitoring assembly is arranged on the support frame, and the monitoring assembly is used for monitoring whether the notches on each wafer glass are aligned along the first direction.

[0011] In some embodiments, when the notches on each wafer glass are aligned along the first direction, a detection gap extending along the first direction is formed between the rotating shaft and the notches of each wafer glass.

[0012] The monitoring assembly comprises signal transceiving elements and reflective baffles, which are arranged on the support frame in the first direction.

[0013] The signal emitted by the signal transceiving elements can reach the reflective baffles through the detection gap.

[0014] In some embodiments, the support frame comprises:

[0015] a frame body;

[0016] a base fixed on the top of the frame body;

[0017] a cover arranged on the top of the base and movably connected with the base, the cover having a first position in which the cover covers the base and a second position in which the cover exposes the wafer glass, and a mounting groove being arranged between the base and the cover.

[0018] In some embodiments, a plurality of first grooves are arranged on the base in the first direction;

[0019] a plurality of second grooves are arranged on the cover in the first direction, the first grooves and the second grooves corresponding to each other and forming the mounting groove when the cover is in the first position.

[0020] In some embodiments, a first hinge seat is arranged on the outer side wall of the base;

[0021] a second hinge seat is arranged on the outer side wall of the cover and opposite to the first hinge seat, the first hinge seat and the second hinge seat being hingedly connected through a hinge shaft, and the cover being rotatable about the hinge shaft to switch between the first position and the second position.

[0024] In some embodiments, the wafer glass alignment device further comprises a second driving member, the second driving member driving the rotating shaft to rotate.

[0025] The wafer glass alignment device is further provided with a control assembly, the control assembly being electrically connected with the second driving member and the first driving member of the wafer glass alignment device, respectively.

[0026] By the technical solution, the rotating shaft of the wafer glass alignment device can rotate along the axis direction of the rotating shaft, and the rotating shaft rotates to drive the wafer glass to rotate, and the notch of each wafer glass is clamped on the rotating shaft under the action of gravity. That is to say, when the rotating shaft rotates, the rotating shaft contacts the outer edge of the wafer, and drives the wafer to rotate in the mounting groove. When the notch on the wafer rotates to be close to the rotating shaft, the notch is clamped on the rotating shaft. Since the notch of the wafer glass is clamped on the rotating shaft, the force exerted by the rotating shaft on the wafer cannot make the wafer rotate again. Finally, under the action of the rotating shaft, the notches of the wafer glasses are aligned in the first direction. Then the wafer glasses can be taken out of the mounting groove by the mechanical hand or other transportation equipment and transported to the next wafer glass processing procedure. The wafer glass alignment device improves the alignment efficiency of the notch on the wafer glass, and greatly reduces the labor cost of aligning the wafer glass. BRIEF DESCRIPTION OF DRAWINGS

[0039] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0040] It should be noted that on the existing production line for notched circular glass sheets 7, when the circular glass sheets 7 are produced and transported to the next process via a conveyor, the notches on each sheet are uneven. Therefore, manual alignment of the notches on each sheet is required, which significantly reduces the production and processing efficiency of the circular glass sheets 7 and increases labor costs. Furthermore, some special circular glass sheets 7 need to be produced in an ultra-clean environment and cannot come into contact with the human body. Contact with the human body could lead to contamination of the circular glass sheets 7, ultimately resulting in a reduction in the quality of the finished product.

[0041] Therefore, see appendix Figs. 1 to 3 As shown, this application discloses a circular glass alignment device for aligning circular glass sheets 7 with notches. The device includes a support frame 1 and a rotating shaft 6. The support frame 1 has multiple notches along a first direction (as shown in the attached diagram). Fig. 2 The mounting slots are spaced apart in the X direction (center), and are used to mount the circular glass pieces 7. A rotating shaft 6 is located at the bottom of the mounting slots and extends along the first direction. The rotating shaft 6 can rotate along its own axis. The rotation of the rotating shaft 6 actuates the circular glass pieces 7, causing the notches of each circular glass piece 7 to engage with the rotating shaft 6 under gravity.

[0042] Specifically, after the production of the wafer glass 7, the wafer glass 7 is transported to the wafer glass aligning device by the conveying device, and then each wafer glass 7 can be installed in the installation slot by the mechanical hand or the like. Since the rotating shaft 6 can rotate along the axis direction of the rotating shaft 6 in the embodiment, and the rotating shaft 6 rotates to drive the wafer glass 7 to rotate, and the notch of each wafer glass 7 is clamped on the rotating shaft 6 under the action of gravity. That is to say, when the rotating shaft 6 rotates, the rotating shaft 6 contacts the outer edge of the wafer glass 7, and drives the wafer glass 7 to rotate in the installation slot. When the notch on the wafer glass 7 rotates to be close to the rotating shaft 6, the notch is clamped on the rotating shaft 6. Since the notch of the wafer glass 7 is clamped on the rotating shaft 6, the force exerted by the rotating shaft 6 on the wafer glass 7 cannot make the wafer glass 7 rotate again. Finally, under the action of the rotating shaft 6, the notch of each wafer glass 7 is aligned in the first direction. Then the mechanical hand or other conveying equipment can take out each wafer glass 7 from the installation slot and transport it to the next wafer glass 7 processing procedure. The wafer glass aligning device of the embodiment improves the alignment efficiency of the notch on the wafer glass 7, and greatly reduces the labor cost of aligning the wafer glass 7.

[0043] In some embodiments, the diameter of the rotating shaft 6 is less than the maximum width of the entrance end of the notch on the wafer glass 7.

[0044] Specifically, in the embodiment, if the diameter of the rotating shaft 6 is greater than the maximum width of the entrance end of the notch on the wafer glass 7, it can cause the notch on the wafer glass 7 to be unable to be clamped on the rotating shaft 6, and finally cause the notches on each wafer glass 7 to be unable to be aligned in the first direction. That is to say, if the diameter of the rotating shaft 6 is greater than the maximum width of the entrance end of the notch on the wafer glass 7, when the rotating shaft 6 drives the wafer glass 7 to rotate, when the notch on the wafer glass 7 is close to the rotating shaft 6, since the maximum width of the entrance end of the notch is too small, the notch cannot be clamped on the rotating shaft 6, and the wafer glass 7 continues to rotate under the action of the rotating shaft 6. Therefore, the notches of each wafer glass 7 cannot be aligned in the first direction.

[0045] In some embodiments, the wafer glass aligning device is further provided with a monitoring assembly 9, and the monitoring assembly 9 is arranged on the support frame 1. The monitoring assembly 9 is used to monitor whether the notch on each wafer glass 7 is aligned in the first direction.

[0046] It can be understood that when the wafer glass 7 is aligned on the wafer glass alignment device, the operator or other equipment needs to know that the notch on each wafer glass 7 is aligned, so the wafer glass alignment device needs to have a judging function after the notch on the wafer glass 7 is aligned in the first direction, so as to facilitate the wafer glass 7 to enter the next processing process, thereby improving the production efficiency of the wafer glass 7. In the embodiment, the monitoring assembly 9 can judge whether the notch on each wafer glass 7 is aligned in the first direction. When the monitoring assembly 9 monitors that the notch on each wafer glass 7 is aligned in the first direction, the monitoring assembly 9 can send an alignment signal to other parts of the wafer glass alignment device, so that the operator or other equipment performs the next step operation on the aligned wafer glass 7.

[0047] In some embodiments, when the notch on each wafer glass 7 is aligned in the first direction, a detection gap 8 extending in the first direction is formed between the rotating shaft 6 and the notch of each wafer glass 7; the monitoring assembly 9 comprises a signal transceiver element 10 and a reflective baffle 11, which are arranged on the support frame 1 in the first direction; wherein the signal emitted by the signal transceiver element 10 can reach the reflective baffle 11 through the detection gap 8.

[0048] Specifically, since the notch has a certain depth in the radial direction of the wafer glass 7, when the notch is clamped on the rotating shaft 6, there is a certain gap between the notch and the rotating shaft 6, and the gaps are aligned in the first direction, thereby forming the detection gap 8. In the embodiment, when the notch on each wafer glass 7 is aligned in the first direction, after the signal transceiver element 10 emits a signal, the signal is transmitted to the reflective baffle 11 through the detection gap 8, and is reflected back to the signal transceiver element 10 through the reflective baffle 11, and when the signal transceiver element 10 receives the signal, an alignment signal is sent to other parts. In some specific embodiments, the signal transceiver element at least comprises a light transceiver and a sound wave transceiver.

[0049] As shown in the accompanying drawings, Fig. 1 The support frame 1 comprises a frame body 2, a base 3 and a gland 4. The base 3 is fixed on the top of the frame body 2, and the gland 4 is arranged on the top of the base 3 and movably connected with the base 3. The gland 4 has a first position covering the base 3 and a second position opening the wafer glass 7, and a mounting groove is arranged between the base 3 and the gland 4.

[0050] In this embodiment, the frame 2 is fixed to the ground by anchor bolts 12. Furthermore, the height of the frame 2 can be adjusted by adjusting the height of the anchor bolts 12 to facilitate the coordination of the circular glass alignment device with other devices. In this embodiment, the base 3 and the pressure cover 4 are movably connected. When the pressure cover 4 is in the first position, it covers the base 3 and encloses the circular glass 7 in the mounting groove, thus protecting and fixing the circular glass 7 and preventing it from shifting in the height direction of the support frame 1 (as shown in the attached figure) under the action of the rotating shaft 6. Fig. 2 It moves upwards in the Z direction. When the cover 4 is in the second position, the cover 4 is open, and the circular glass 7 can be taken out from the mounting groove.

[0051] In actual operation, the pressure cap 4 is first moved to the second position. Then, each round glass piece 7 is placed into its respective mounting slot using a robotic arm or other equipment, and the pressure cap 4 is moved to the second position to protect the glass. Subsequently, the rotating shaft 6 is activated. After the monitoring component 9 issues an alignment signal, the pressure cap 4 is moved to the first position, and each round glass piece 7 is transported to the next processing step using a robotic arm or other transport equipment.

[0052] In some embodiments, the base 3 is provided with a plurality of first grooves spaced apart along a first direction; the cover 4 is provided with a plurality of second grooves spaced apart along a first direction. When the cover 4 is in a first position, the first grooves and the second grooves correspond one-to-one and surround each other to form an installation groove.

[0053] In this embodiment, the bottom of each first groove is penetrated by the rotating shaft 6. When the actual disc alignment device is working, the disc glass 7 is first placed into the first groove. Under the action of gravity, the disc glass 7 contacts the outer surface of the rotating shaft 6. When the rotating shaft 6 rotates, the disc glass 7 rotates and the notch engages with the rotating shaft 6. In a specific embodiment, both the first and second grooves are semi-circular. The semi-circular design of the first groove facilitates the placement of the disc glass 7 and prevents wear between the disc glass 7 and the first groove. Similarly, the semi-circular design of the second groove prevents wear between the second groove and the disc glass 7 after the pressure cap 4 is placed on the base 3. Furthermore, it is worth mentioning that the coefficient of friction of the inner walls of the first and second grooves should be minimized to prevent the disc glass 7 from being damaged by the inner walls of the first and second grooves when rotating within the mounting groove.

[0054] As attached Fig. 3 As shown, a first hinge seat 13 is provided on the outer side wall of the base 3; a second hinge seat 14 is provided on the outer side wall of the cover 4 opposite to the first hinge seat 13. The first hinge seat 13 and the second hinge seat 14 are hinged together by a hinge shaft 15. The cover 4 can rotate around the hinge shaft 15 to switch between a first position and a second position.

[0055] Specifically, the hinge shaft 15 is arranged between the first hinge base 13 and the second hinge base 14, and extends along a first direction, and the end of the hinge shaft 15 is fixed on the first hinge base 13 and the second hinge base 14 through a copper sleeve. When an external force along the height direction is applied to the pressing cover 4, the pressing cover 4 rotates around the hinge shaft 15 and moves to a second position, at which the pressing cover 4 opens the circular glass 7 in the mounting groove, i.e., the circular glass 7 can be taken out of the mounting groove. When an external force in the direction opposite to the height direction is applied to the pressing cover 4, the pressing cover 4 rotates around the hinge shaft 15 and moves to a first position to cover the base 3 so as to protect the circular glass 7, avoiding damage of the circular glass 7 caused by external force when the circular glass alignment device is working.

[0056] In some embodiments, the circular glass alignment device further comprises a first driving member arranged between the base 3 and the pressing cover 4, and the first driving member drives the pressing cover 4 to switch between the first position and the second position.

[0057] Specifically, the first driving member can apply an external force along the height direction or in the direction opposite to the height direction to the pressing cover 4 to switch the pressing cover 4 between the first position and the second position. In some embodiments, the first driving member is electrically connected with the monitoring assembly 9, and when the monitoring assembly 9 monitors that the notch on each circular glass 7 is aligned along the first direction, the monitoring assembly 9 sends an alignment signal, and the first driving member drives the pressing cover 4 to move from the first position to the second position according to the alignment signal, at which the pressing cover 4 is opened and the circular glass 7 can be taken out of the mounting groove.

[0058] In some embodiments, the first driving member comprises a pneumatic cylinder 17 fixed on the support frame 1, and a piston rod 19 of the pneumatic cylinder 17 extends along the height direction of the support frame 1, and the piston rod 19 is hinged to the pressing cover 4. In other embodiments, the end of the piston rod 19 is further provided with a floating joint 16, which is self-inclined and has a buffering effect, thereby avoiding the problem of excessive internal stress on the piston rod 19 when the inclination angle between the piston rod 19 and the pressing cover 4 is too large. Of course, the first driving member can also be a linear motor, and the output end of the linear motor is connected with the pressing cover 4.

[0059] In some embodiments, the circular glass alignment device further comprises a second driving member 5 driving the rotating shaft 6 to rotate, and the circular glass alignment device is further provided with a control assembly 18 electrically connected with at least the second driving member 5 and the first driving member of the circular glass alignment device.

[0060] Specifically, the second driving member 5 is an electric motor, the rotating shaft 6 is connected with the output end of the electric motor to drive the rotating shaft 6 to rotate, and the end of the rotating shaft 6 away from the electric motor is fixed on the support frame 1 through a check ring. In the embodiment, the wafer glass aligning device further comprises a power supply and a power supply switch, and the control assembly 18 comprises a control panel and control buttons, and the control panel is connected with the first driving member, the second driving member 5, the monitoring assembly 9, the power supply and the power supply switch respectively. The control buttons are arranged on the control panel and are used for being controlled by an operator, that is, the operator can control the rotating shaft 6, the air cylinder 17 and the wafer glass aligning device to be turned on and turned off through the control buttons. In addition, in some embodiments, the monitoring assembly is electrically connected with the control panel, that is, after the monitoring assembly sends an alignment signal to the control panel, the control panel controls the second driving member 5 to stop working.

[0061] In summary, the wafer glass aligning device provided by the application can rotate the rotating shaft 6 to rotate the wafer glass 7, and make the gaps of the wafer glasses 7 be clamped on the rotating shaft 6 under the action of gravity, so that the gaps of the wafer glasses 7 are finally aligned in the first direction, the alignment efficiency of the gaps of the wafer glasses 7 is improved, and the labor cost is greatly reduced. In addition, the monitoring assembly 9 is arranged in the application, that is, when the gaps of the wafer glasses 7 are aligned in the first direction, the monitoring assembly 9 can monitor the alignment of the gaps of the wafer glasses 7 through the detection gap 8, and then send an alignment signal, so as to facilitate the next processing procedure of the wafer glasses 7. Finally, the movable connection between the gland nut 4 and the base 3 in the embodiment facilitates the taking out and installation of the wafer glasses 7.
