[0020] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0021] Reference Figure 1-3The utility model provides a scribing and breaking device for a glass substrate, comprising: a frame 1, a scribing mechanism 4, a first glass carrying platform 2, a second glass carrying platform 3, a first vacuuming mechanism and a second vacuuming mechanism;

[0022] The first glass carrier 2 and the second glass carrier 3 are sequentially arranged on the frame 1 at intervals along the moving direction of the glass, and the second glass carrier 3 can rotate downstream in the moving direction of the glass relative to the first glass carrier 2 to break the glass or rotate upstream in the moving direction of the glass to reset the glass; the first glass carrier 2 and the second glass carrier 3 are both provided with vacuum adsorption holes for vacuum adsorption of the glass, the vacuum adsorption hole of the first glass carrier 2 is connected to the first vacuum pumping mechanism, and the vacuum adsorption hole of the second glass carrier 3 is connected to the second vacuum pumping mechanism;

[0023] The marking mechanism 4 is arranged on the frame 1 between the first glass loading platform 2 and the second glass loading platform 3, and the marking mechanism 4 can move closer to the glass placed on the first glass loading platform 2 and the second glass loading platform 3 relative to the frame 1 to mark or move away from the glass placed on the first glass loading platform 2 and the second glass loading platform 3 to reset.

[0024] In a specific implementation, when the glass substrate is moved onto the first glass loading platform 2 and the second glass loading platform 3, the first vacuum pumping mechanism and the second vacuum pumping mechanism work to adsorb and fix the glass substrate onto the first glass loading platform 2 and the second glass loading platform 3;

[0025] Next, the scribing mechanism 4 approaches the glass substrate and scribes the glass substrate, such as Figure 1 As shown;

[0026] When the scribing is completed, the scribing mechanism 4 is reset, and the second glass carrier 3 is rotated downstream in the moving direction of the glass to a predetermined angle to break the glass. The glass bait generated by breaking the glass is adsorbed on the second glass carrier 3. Figure 2 As shown;

[0027] When the breaking is completed, the second vacuum mechanism is closed, and the second glass carrying platform 3 continues to rotate downstream in the moving direction of the glass, and the glass bait on the second glass carrying platform 3 falls naturally due to the action of gravity. Figure 3 As shown;

[0028] When the glass bait on the second glass carrying platform 3 falls off, the second glass carrying platform 3 rotates upstream in the moving direction of the glass to reset, and the first vacuuming mechanism is closed.

[0029] The utility model can realize continuous and efficient scribing and breaking operations of glass substrates, reduce the generation of incomplete breaking and fragments, and improve production efficiency. At the same time, the device has a simple structure, convenient operation, and low maintenance cost, and can be widely used in various types of precision cutting machines.

[0030] In order to improve the scribing effect and the breaking effect, in the present embodiment, the interval between the first glass carrying platform 2 and the second glass carrying platform 3 conforms to a preset interval distance range.

[0031] In this embodiment, a controller is further included, and the scribing mechanism 4, the first glass carrying platform 2, the second glass carrying platform 3, the first vacuuming mechanism and the second vacuuming mechanism are electrically connected to the controller respectively.

[0032] With such arrangement, the controller can control the scribing mechanism 4, the first glass carrying platform 2, the second glass carrying platform 3, the first vacuuming mechanism and the second vacuuming mechanism to automatically scribing and breaking the glass substrate.

[0033] Specifically, when the glass substrate moves to the first glass supporting platform 2 and the second glass supporting platform 3, the controller controls the first vacuum pumping mechanism and the second vacuum pumping mechanism to work so that the glass substrate is adsorbed and fixed on the first glass supporting platform 2 and the second glass supporting platform 3; then, the scribing mechanism 4 is controlled to move so that the scribing mechanism 4 approaches the glass substrate and scribes the glass substrate; when the scribing is completed, the controller controls the scribing mechanism 4 to reset, and controls the second glass supporting platform 3 to rotate to a predetermined angle downstream in the moving direction of the glass to break the glass, and the glass bait generated by the breaking is adsorbed on the second glass supporting platform 3; when the breaking is completed, the controller turns off the second vacuum pumping mechanism, and controls the second glass supporting platform 3 to continue to rotate downstream in the moving direction of the glass, and the glass bait on the second glass supporting platform 3 falls naturally due to the action of gravity; when the glass bait on the second glass supporting platform 3 falls, the controller controls the second glass supporting platform 3 to rotate upstream in the moving direction of the glass to reset, and turns off the first vacuum pumping mechanism.

[0034] In a further embodiment, the first glass carrying platform 2 and the second glass carrying platform 3 are both provided with glass presence sensors for sensing the glass presence status, and the glass presence sensors are both electrically connected to the controller.

[0035] In this way, when the glass presence sensors on the first glass supporting platform 2 and the second glass supporting platform 3 both sense the glass substrate, the glass presence sensors transmit the sensed presence status to the controller, so that the controller can control the scribing mechanism 4, the first glass supporting platform 2, the second glass supporting platform 3, the first vacuuming mechanism and the second vacuuming mechanism to automatically scribing and breaking the glass substrate in time.

[0036] In this embodiment, a bait collection box for collecting broken glass baits is provided on the frame 1 on the side of the second glass carrying platform 3 away from the first glass carrying platform 2 .

[0037] In a specific implementation, when the second glass supporting platform 3 is rotated to a certain angle, the second vacuum mechanism is closed, and the broken glass bait automatically falls into the bait collection box under the action of gravity.

[0038] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
