The process flow of the TFT-LCD cutting production line is shown in FIG. 13, in the cutting process, a cutting line is left on the surface when a cutter wheel of a cutting machine passes through the glass substrate, and cracks are generated in the glass substrate; in the breaking process, the breaking machine applies a suitable pressure from the back of the glass substrate corresponding to the position of the cutting line, so as to increase the stress perpendicular to the end of the crack of the glass substrate, accelerate the crack propagation, and shorten the time for completely separating the glass substrate, as shown in fig. 14. Among them, breakage is a key process of the TFT-LCD glass cutting line, which determines whether the panel can be completely separated.

As will be readily understood, in order to ensure the stability of the transfer of the panels, the transfer platen 3 has to be designed with a sufficient length in the Y direction to achieve a stable support of the panels, which causes the following problems: when the transfer platen 3 sucks the panel Y to move to the position just before contacting the breaking platen 5, since the breaking position of the panel is generally set at the middle of the panel, the transfer platen 3 still needs to move further to the breaking platen 5 side, and at this time, since the transfer platen 3 is placed in the transfer gap 21 and the sucking panel and the breaking platen 5 are at the same level, if the notch 52 is not provided, the transfer platen 3 cannot move further to the breaking platen 5 side. Therefore, the end of the breaking platen 5 close to the supporting platen 2 needs to be provided with a notch 52 to avoid the movement of the transfer platen 3, so that the cutting line of the panel can be positioned between the adsorption platen and the breaking platen 5.

s0, adjusting the upper surfaces of the supporting bedplate 2, the conveying bedplate 3 and the breaking bedplate 5 to be the same horizontal plane, and enabling the conveying bedplate 3 to be completely positioned in the conveying gap 21 to wait for receiving materials;

s2, releasing vacuum and blowing air by the support bedplate 2;
s3, the first Z-direction linear driving pair 44 acts to drive the conveying bedplate 3Z to rise upwards until the panel is higher than the upper surface of the supporting bedplate 2;
s4, the first Y-direction linear driving pair 43 acts to drive the conveying platen 3 to move close to the breaking platen 5 along the conveying gap 21 until the cutting line on the panel is positioned between the supporting panel and the breaking section plate;
s5, the first Z-direction linear driving pair 44 acts to drive the conveying platen 3Z to descend downwards until the panel falls on the supporting platen 2 and the breaking platen 5;
s6, releasing vacuum by the transfer platen 3, and generating vacuum by the support platen 2 and the breaking platen 5 to adsorb and fix the panel;
and S7, the second Y-direction linear driving pair 63, the second Z-direction linear driving pair 69 and the rotary driving pair 66 move in a combined manner to control the panel part adsorbed by the breaking-off platen 5 to be forcedly separated from the panel part adsorbed by the supporting platen 2, so that the breaking-off of the panel is completed.
According to the panel breaking mechanism of the embodiment, the panel breaking table plate 5 is controlled to move along a target path, so that on one hand, the extrusion of the panels on two side surfaces of a cutting line can be avoided, the phenomena of point breaking, pit breaking and the like are avoided, and the quality of the section is ensured; on the other hand, the frame glue between the panels can be completely separated through displacement, so that the interference on sorting, carrying and detection is avoided. In addition, the structure does not need to apply fracture pressure on the back, and can avoid damage to the glass substrate, particularly the terminal part of the substrate, so that the structure can be suitable for breaking the thin panel.
The principle of the present embodiment is explained in detail below:
when the panel is broken off, the breaking-off type required by the manufacturer can be divided into two step sections shown in fig. 7 and 8, and the flush section is a special case that the length of the step section is zero, so that the step section can be analyzed.
The analysis was performed by taking the step cross section shown in FIG. 7 as an example.
In fig. 9, a point O represents a center point of the rotation axis of the breaking-off platen 5, a point a represents a virtual intersection point of the passing point O perpendicular to the upper surface of the breaking-off platen 5, a point B represents a contact point of the panel with the edge of the breaking-off platen 5, and points C, D, E, and F represent four contact points sequentially distributed from bottom to top at the cutting line before the panel is separated. Wherein, the line segments OA and AB are determined by the structural size of the breaking platen 5, and the values are fixed, such that OA = a and AB = b; the line segment BC is determined by the typesetting of the panel, the numerical value is not fixed, and BC = c.
The movement of the breaking platen 5 is divided into clockwise rotation and counterclockwise rotation.
I. As shown in fig. 10, in order to ensure that the panels are not in contact with each other during clockwise rotation, the panel adsorbed on the break-off platen 5 side needs to be rotated by an angle DCD ' clockwise with point C as a rotation center, the point D ' is moved to point D ', the point E ' is moved to point E ', the point F ' is moved to point F ', and the point O ' is moved to point O '. In the rotating process, D and D ' on the panel are on a circle with the C point as the center and the CD as the radius, E and E ' are on a circle with the C point as the center and the CE as the radius, and F ' are on a circle with the C point as the center and the CF as the radius.
As shown in fig. 11, the moving breaking platen 5 is selected as a combined motion study object, and the structure of the breaking platen 5 is simplified for the convenience of analysis, and only points O, C, and a remain. The AC rotates clockwise by an angle alpha by taking the point O as a rotation center, the point C moves to the point C ', the point A moves to the point A ', the perpendicular line passing through the point C ' and serving as the AC is intersected with the point H, the extension line of the CA is intersected with the point A ' C ' at the point G, and the extension line of the OA is intersected with the point A ' C ' at the point K.
As can be easily understood, the rotating motion of the breaking-off platen 5 moves the point C to the point C ', the height running distance along the vertical direction is C ' H, and the moving distance along the horizontal direction is CH, so that in order to keep the point position of the point C after the combined motion of the breaking-off platen 5 unchanged, the breaking-off platen 5 needs to move downwards by the distance C ' H along the vertical direction, and move by the distance CH towards the side of the supporting platen 2 along the horizontal direction.
Given OA '= OA = a, AB = b, BC = c, angle COC' = CGC '= AOA' = α, let angle AOG = β, then:
wherein
Therefore, it is not only easy to use
Substituting β into the above relationships for CH and C' H, the expressions for a, b, C, and α are obtained. Namely: when the breaking-off table plate 5 rotates by alpha, the vertical downward movement is carried out by a distance C' H, and the horizontal movement is carried out by a distance CH close to the supporting table plate 2 side, so that the position of the C point is unchanged during rotation, and the breaking-off of the panel is completed.
As shown in fig. 12, in order to ensure that the panels are not in contact with each other during counterclockwise rotation, the panel adsorbed on the break-off table plate 5 side needs to be rotated counterclockwise by an angle EFE 'with the point F as a rotation center, the point C is moved to the point C', the point D is moved to the point D ', and the point E is moved to the point E'. In the rotating process, C and C ' on the panel are on a circle with the F point as the center and CF as the radius, D and D ' are on a circle with the F point as the center and DF as the radius, and E ' are on a circle with the F point as the center and EF as the radius.
The moving breaking platen 5 is still selected as the study object of the combined movement, and the specific analysis process is similar to the clockwise rotation analysis in the step I, and is not described in detail here.
The snapping operation of the step section and the panel flat section shown in fig. 8 can be performed using both clockwise rotation and counterclockwise rotation with reference to the above analysis process.

Further, the two sets of visual alignment assemblies 7 are distributed along the X direction and driven toward and away from each other.
Specifically, a bidirectional screw pair 72 is installed on the gantry 71, the two sets of vision alignment assemblies 7 are respectively installed on two moving blocks of the bidirectional screw pair 72, and the screw rotates to drive the two moving blocks to approach or separate from each other, so that the two sets of vision alignment assemblies 7 are driven to approach or separate from each other.
In specific implementation, the distance between the two sets of visual alignment assemblies 7 is adjusted, so that the positioning requirements of panels with different sizes can be met.

Specifically, the communication holes X on the support platen 2 are arranged in the direction, and the communication holes 82Y on the transfer platen 3 and the breaking platen 5 are arranged in the direction. Of course, as an alternative embodiment, the communication holes 82 on the support platen 2 may be arranged in the Y-direction, and the communication holes 82 on the transfer platen 3 and the breaking platen 5 may be arranged in the X-direction.
