Description

Technical Field

[0001] The utility model belongs to the technical field of glass substrate processing equipment, and particularly relates to an edge grinding positioning mechanism. Background Technique

[0002] In the production process of glass substrates, the ITO edges of the glass substrates are too sharp, which causes damage to the subsequent pin insertion process and has a certain impact on the safety of operators. At the same time, the pin insertion yield is improved. Therefore, a set of equipment is designed to process the ITO edges of glass substrates, that is, a diamond grinding wheel is used to grind the glass substrates to achieve the desired effect. This equipment can grind the glass substrates used in the liquid crystal and other electronic industries, and can perform two-sided (four-sided) grinding at one time.

[0003] After retrieval, the patent publication number CN208528712U discloses a glass edge grinding positioning mechanism, which includes a base, a processing platform, and an edge grinding head. A processing platform is installed at the top of one side of the base, a lifting assembly is installed on the other side of the base, a glass supporting wheel is installed on the top of the processing platform, and a limiting plate is fixed on the top of the processing platform at one end of the lifting assembly; a positioning seat is movably installed on the top of the lifting assembly, a hinge seat is fixed on the top of the positioning seat, a grinding arm is hinged on the hinge seat through a hinge shaft, and an edge grinding head is installed on the grinding arm. An adjusting arm is hinged on the positioning seat on one side of the grinding arm, an adjusting groove is provided on the adjusting arm, an adjusting bolt is provided in the adjusting groove, and the adjusting bolt is meshed with the grinding arm; an angular scale is installed on the top of the positioning seat on the other side of the grinding arm, and a scale groove is provided along the arc length direction on the angular scale. After adopting the above scheme, the structure of the utility model is reasonable and the adjustment effect is good.

[0004] In the actual production process, there are certain errors in the previous process of cutting glass substrates, which will cause changes in the edge grinding amount during the subsequent process of grinding glass substrates, easily cause ITO edge collapse of glass substrates, and cause damage to diamond grinding wheels. Therefore, we propose an edge grinding positioning mechanism to solve the existing problems. Content of the Utility Model

An output belt, a first edge grinding platform and a first grinding head mechanism are arranged below the first blanking arm. A second grinding head mechanism and a second edge grinding platform are installed at the rear of the other side of the top of the frame, and the second grinding head mechanism is located on one side of the second edge grinding platform.

[0008] Further, support feet and rollers are installed at the bottom end of the frame, and the rollers are located on one side of the support feet.

[0012] Further, a servo motor is arranged at the front end of the clamping cylinder.

[0013] By means of the above technical solution, the present utility model provides an edge grinding positioning mechanism, which has at least the following beneficial effects: through the coordinated setting of a series of structures, the present utility model uses a cylinder to limit the front stop bar of the glass substrate, drives the rear stop bar to push forward through the torque mode of the servo motor, the rear stop bar contacts the glass substrate, and feeds back through the torque. After detecting that the torque reaches, the actual position of the rear stop bar is accurately positioned. At the same time, the clamping cylinder clamps the driving screw rod to achieve real-time and accurate positioning of the glass substrate. Therefore, the present utility model can solve the influence of the error of the glass substrate on the edge grinding amount, resulting in chipping of the ITO of the glass substrate and damage to the diamond grinding wheel, and has strong practicability.

Both the first blanking arm 1 and the second blanking arm 2 can be set on the touch screen according to the blanking direction. Below the first blanking arm 1, there are a discharge belt 4, a first edge grinding platform 3, and a first grinding head mechanism 5. The discharge belt 4 is driven by a motor to convey the edge-ground glass substrate to connect with downstream equipment. At the rear end of the other side of the top end of the frame 9, a second grinding head mechanism 6 and a second edge grinding platform 7 are installed, and the second grinding head mechanism 6 is located on one side of the second edge grinding platform 7. Both the first grinding head mechanism 5 and the second grinding head mechanism 6 adopt double grinding heads for grinding.

Adsorption plates 701 are provided on both the first edge grinding platform 3 and the second edge grinding platform 7. Both the first edge grinding platform 3 and the second edge grinding platform 7 use vacuum adsorption for the glass substrate. After positioning, they are driven by a servo motor to move in the X-axis direction. On one side of the upper surface of the adsorption plate 701, there is a rear stop bar 704. At the rear end of the adsorption plate 701, there is a front stop bar 705. At the front end of the adsorption plate 701, there is a clamping cylinder 702.
