Description

Technical Field

[0001] This patent application relates to the field of glass vertical transmission automated production lines in the liquid crystal panel industry, and in particular to a glass carrier clamping technology. Background Art

[0002] With the large-scale production of various LCD panel companies, there are more and more glass vertical transmission automated production lines, and the stability requirements for the glass loading and unloading tools on the automated production lines are also more stringent. A reliable clamping device is urgently needed to ensure the stability of the glass loading and unloading tools on the automated production lines.

[0003] The panel workshop has a high degree of automation. The ordinary glass carrier clamping device is driven by a single cylinder. The movement trajectory of the clamping actuator is a straight line. It does not have the ability to adaptively align at a certain angle and has a low fault tolerance. Due to the differences in the position and external dimensions of each glass carrier, the glass carrier clamping will be unstable, causing the line to stop, which in turn leads to reduced utilization rate and yield.

[0004] Therefore, a reliable clamping device is needed to ensure the stability of the glass upper and lower tools on the automated production line, and meet the requirements of high fault tolerance, simple clamping action, smooth clamping, and fast clamping speed. Utility Model Content

[0007] Furthermore, the guide unit includes a positioning guide wheel, a positioning guide wheel bracket, a guide rail mounting plate, a limit plate, a slider mounting block, a transverse spring, and a spring mounting seat; the positioning guide wheel is mounted at the end of the positioning guide wheel bracket, the positioning guide wheel bracket is connected to the slider mounting block, the limit plate is mounted at the end of the slider mounting block, the spring mounting seat is mounted at the end of the guide rail mounting plate, and the transverse spring is clamped between the limit plate and the step hole of the spring mounting seat. The step of the limit plate and the guide rail mounting plate limits the initial compression of the transverse spring to ensure that the transverse spring does not fall out.

[0008] Furthermore, the clamping unit includes an clamping guide wheel, an clamping guide wheel bracket, a guide wheel mounting plate, a rotating bracket, a longitudinal spring, and a guide rail slider; the clamping guide wheel is installed on the clamping guide wheel bracket, the clamping guide wheel bracket is connected to the guide wheel mounting plate, the guide wheel mounting plate is connected to the rotating bracket, the rotating bracket is connected to the rotating bracket seat through a connecting shaft, the longitudinal spring is clamped between the step hole of the rotating bracket and the rotating bracket seat, and the guide rail slider is installed on the guide rail mounting plate.

[0010] Furthermore, the guide unit is connected to the guide wheel mounting plate via a guide rail mounting plate, thereby ensuring the rotational synchronization between the guide unit and the clamping unit.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] As attached Figure 1 As shown in FIG. 4 , the carrier 200 is loaded and unloaded by opening the carrier glass clamp 200-2, and the glass is clamped by closing the carrier glass clamp 200-2; the clamping mechanism is connected to the pneumatic slide 116, and the pneumatic slide 116 is installed on the mechanism fixing plate 108; the clamping structure includes a rotating bracket seat 113, a guide unit, and an unclamping unit, wherein the unclamping unit and the guide unit are connected to the pneumatic slide 116 via the rotating bracket seat 113.

[0019] In the guide unit, the positioning guide wheel 101 is installed at the end of the positioning guide wheel bracket 102, the positioning guide wheel bracket 102 is connected to the slider mounting block 105, the limit plate 104 is installed at the end of the slider mounting block 105, the spring mounting seat 107 is installed at the end of the guide rail mounting plate 103, and the transverse spring 106 is stuck between the step hole of the limit plate 104 and the spring mounting seat 107; when the pneumatic slide 116 drives the mechanism forward, when the positioning guide wheel 101 contacts the low-tight load guide block 200-1, the slider mounting block 105 will drive the positioning guide wheel 101, the positioning guide wheel bracket 102, and the limit plate 104 to squeeze the transverse spring 106 and move backward; the step of the limit plate 104 and the guide rail mounting plate 103 limits the initial compression of the transverse spring 106 to ensure that the transverse spring 106 does not fall out;

[0020] In the clamping unit, the clamping guide wheel 109 is installed on the clamping guide wheel bracket 110, the clamping guide wheel bracket 110 is connected to the guide wheel mounting plate 111, the guide wheel mounting plate 111 is connected to the rotating bracket 112, the rotating bracket 112 is connected to the rotating bracket seat 113 through the connecting shaft, and the longitudinal spring 115 is stuck between the step hole of the rotating bracket 112 and the rotating bracket seat 113; when the pneumatic slide 116 drives the mechanism forward, the clamping guide wheel 109 contacts and opens the carrier glass clamp 200-2 to a specified angle; if there is a slight positioning error, the rotating bracket 112 can achieve a certain angle rotation by compressing the longitudinal spring 115, thereby ensuring the correct opening of the carrier glass clamp 200-2; the cover plate 114 is installed on the upper rear part of the rotating bracket seat 113 to limit the initial compression amount of the longitudinal spring 115 to ensure that the longitudinal spring 115 does not fall out;

[0022] During normal operation, the pneumatic slide 116 moves to drive the upper mechanism forward, the positioning guide wheel 101 contacts and presses against the carrier guide block 200-1, and at the same time, the clamping guide wheel 109 contacts and opens the carrier glass clamp 200-2 to a specified angle, ensuring that the downstream equipment can remove the glass from the glass carrier; if there is a certain error in the positioning of the carrier 200 and the clamping device, the transverse spring 106 and the longitudinal spring 116 are compressed during the process of the positioning guide wheel 101 contacting and pressing against the carrier guide block 200-1, which can realize the rotation of the rotating bracket 112 at a certain angle, thereby ensuring that the clamping guide wheel 109 correctly contacts and opens the carrier glass clamp 200-2 to a specified angle.
