Description

Technical Field

[0001] This utility model belongs to the field of glass substrate production technology, and specifically relates to a glass substrate packaging box position correction device. Background Technology

[0002] As a core material in display panel manufacturing, the precise positioning of glass substrates during transportation directly impacts production yield and operational efficiency. In automated production lines, packaging boxes need to be accurately transported to designated workstations via conveyor systems. However, due to factors such as equipment vibration and inertial impact, packaging boxes often experience positional deviations. Traditional mechanical straightening devices often employ rigid pushing methods, which can easily lead to micro-cracks in the glass substrate due to stress concentration. Furthermore, the straightening process carries the risk of jamming, causing fluctuations in production cycle time and a decrease in yield. Utility Model Content

[0003] To address the problems of high risk of microcracks in glass substrates and easy jamming during the straightening process caused by rigid contact in existing packaging box straightening devices, a new glass substrate packaging box position straightening device is proposed. This device achieves flexible contact with the sidewalls through an array of guide rollers, and uses an arc-shaped transition structure to complete gradual position correction. This eliminates the risk of hard collisions while improving the smoothness of straightening and positioning accuracy. The present invention provides the following technical solution:

[0004] A glass substrate packaging box position correction device includes a mounting frame erected on a conveying device. Two correction components are symmetrically arranged on the mounting frame. Each correction component includes a lifting drive device mounted and connected to the mounting frame. A mounting plate is fixedly connected to the lower end of the lifting drive device. A rotation drive device is mounted on the mounting plate. A guide plate is fixedly connected to the lower end of the rotation drive device. The guide plate includes a straight section and an arc section. Guide rollers are rotatably connected to the guide plate. The guide rollers are arranged in an array along the straight section and the arc section. The guide rollers protrude laterally from the guide plate.

[0005] Preferably, the mounting bracket is equipped with a transverse drive device and a bearing seat, a lead screw is rotatably connected to the bearing seat, the output end of the transverse drive device is connected to the lead screw, a lead screw nut is rotatably connected to the lead screw, the lead screw nut is provided with a clearance hole and a threaded hole for threaded connection of the lead screw, the mounting bracket is provided with a clearance groove, the lifting drive device is mounted and fixed on the lead screw nut, and its output end passes through the clearance hole and clearance groove and is connected to the mounting plate.

[0006] Preferably, there are two leadscrew nuts arranged symmetrically about the leadscrew, and the thread directions on the left and right sides of the leadscrew are opposite.

[0007] Preferably, a guide seat is fixedly connected to the mounting bracket, and a guide hole is provided on the lower side of the lead screw nut, the guide hole being slidably connected to the guide seat.

[0008] Preferably, the screw hole and the guide hole are respectively located on the front and rear sides of the lead screw nut.

[0009] Preferably, the guide plate is rotatably connected to the guide roller about a vertical axis.

[0010] Preferably, the output end of the lifting drive device is connected to the centroid of the mounting plate, and a balance block for balancing the torque of the rotary drive device is fixed on the mounting plate. The balance block and the rotary drive device are arranged symmetrically about the centroid of the mounting plate.

[0011] Preferably, the mounting plate is elliptical, and the rotation drive device is installed at the edge of the mounting plate.

[0012] Preferably, the mounting frame is provided with a movable base for connecting the conveying device, and the mounting frame is lockably slidably connected to the movable base.

[0013] Preferably, the mounting bracket is provided with a locking hole, and a bolt is passed through the locking hole and then pressed against the movable base to achieve locking.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. By densely arranging rotatable guide rollers in the straight and curved sections of the guide plate, the contact surface of the packaging box sidewall is transformed from rigid contact to flexible rolling friction, effectively dispersing contact stress and eliminating the potential for micro-cracks in the glass substrate caused by traditional mechanical pushing. The curved transition section guides the packaging box to achieve non-abrupt position correction, which, combined with the precise centering of the straight section, makes the correction process both smooth and accurate, significantly reducing the risk of jamming and improving the stability of the production line cycle time;

[0016] 2. The screw and nut transmission system with double thread reverse design, together with the transverse drive device, realizes the equal speed and opposite movement of the two sides of the correction components, ensuring that the correction action is strictly symmetrical, eliminating the position deviation that may be caused by single-sided drive. Combined with the vertical guide design of the clearance groove and clearance hole, the movement trajectory of the lifting drive device is free from interference and blockage, which significantly improves the stability of equipment operation and long-term reliability.

[0017] 3. The independent guide seat and the guide hole of the lead screw nut form a double support, which improves the stability of the movement of the lead screw nut, and thus improves the stability of the lateral movement of the guide roller. Attached Figure Description

Detailed Implementation

[0022] The directional terms mentioned in the following embodiments, such as "up", "down", "left", and "right", are only for reference to the accompanying drawings. Therefore, the directional terms used are for illustration and not for limiting the invention of this utility model.

[0023] like Figure 1-3 As shown, a glass substrate packaging box position correction device includes a mounting frame 2 mounted on a conveying device 1. Two correction components 3 are symmetrically arranged on the mounting frame 2. Each correction component 3 includes a lifting drive device 31 mounted and connected to the mounting frame 2. A mounting plate 32 is fixedly connected to the lower end of the lifting drive device 31. A rotary drive device 33 is mounted on the mounting plate 32. A guide plate 34 is fixedly connected to the lower end of the rotary drive device 33. The guide plate 34 includes a straight section 341 and an arc-shaped section 342. A guide roller 35 is rotatably connected to the guide plate 34 around a vertical axis. The guide roller 35 is arranged in an array along the straight section 341 and the arc-shaped section 342. The guide roller 35 protrudes laterally from the guide plate 34. The arrayed guide roller 35 structure achieves flexible contact with the side wall of the packaging box, effectively reducing the risk of hidden cracks in the glass substrate caused by hard impact. At the same time, the arc-shaped section 342 provides a gradual guiding transition, and then the straight section 341 achieves correction, significantly improving the smoothness and efficiency of position correction.

[0024] Specifically, the lifting drive device 31 uses a cylinder, and the rotary drive device 33 uses a servo motor.

[0025] Furthermore, a transverse drive device 4 and a bearing 5 are mounted on the mounting frame 2. A lead screw 6 is rotatably connected to the bearing 5. The output end of the transverse drive device 4 is connected to the lead screw 6. A lead screw nut 7 is rotatably connected to the lead screw 6. There are two lead screw nuts 7 symmetrically arranged about the left and right sides of the lead screw 6. The thread directions on the left and right sides of the lead screw 6 are opposite. The lead screw nut 7 is provided with a clearance hole and a threaded hole for threaded connection of the lead screw 6. The mounting frame 2 is provided with a clearance groove 9, which runs vertically through the mounting frame 2 to ensure that the vertical movement of the lifting drive device 31 is not affected by lateral displacement. The lifting drive device 31 is mounted and fixed on the lead screw nut 7, and its output end passes through the clearance hole and clearance groove 9 and is connected to the mounting plate 32, so that the two side alignment components 3 can move synchronously in opposite directions and move in opposite directions at the same speed, realizing automatic centering and effectively improving the stability of equipment operation.

[0026] Furthermore, a guide seat 8 is fixedly connected to the mounting bracket 2, and a guide hole is provided on the lower side of the lead screw nut 7. The guide hole is slidably connected to the guide seat 8. The guide seat 8 can provide guidance and support, effectively disperse the lateral force, and prevent the lead screw 6 from bearing radial load and deviating to the side. At the same time, the gap between the guide hole and the guide seat 8 is controlled within 0.1mm to ensure that the movement trajectory of the alignment component 3 is accurate and controllable.

[0027] Furthermore, the screw hole and guide hole are respectively located on the front and rear sides of the lead screw nut 7, providing stable support for the lead screw nut 7, improving the smoothness and stability of the movement of the lead screw nut 7, and extending the service life of key transmission components.

[0028] Furthermore, the output end of the lifting drive device 31 is connected to the centroid of the mounting plate 32. A balance block 10 for balancing the torque of the rotary drive device 33 is fixed on the mounting plate 32. The balance block 10 and the rotary drive device 33 are symmetrically arranged about the centroid of the mounting plate 32 to eliminate eccentric loads and make the output torque of the rotary drive device 33 act stably on the guide plate 34, significantly improving the action response speed.

[0029] Furthermore, to save external space and to reserve sufficient configuration space for the balance block 10, the mounting plate 32 is set to an elliptical shape, and the rotary drive device 33 is installed at the edge of the mounting plate 32, which improves the compactness of the structure.

[0030] Furthermore, a movable base 11 for connecting the conveying device 1 is provided under the mounting frame 2. The mounting frame 2 is slidably connected to the movable base 11. The mounting frame 2 is provided with locking holes. After the bolt passes through the locking holes, it is locked to the movable base 11, so that the equipment has a lateral position adjustment function. The working position can be quickly adjusted according to the packaging boxes of glass substrates of different specifications. The bolts and locking holes can be used to lock the position, ensuring that the equipment is positioned stably and reliably during operation.

[0031] In use, the lower conveyor 1 carries the packaging box from front to back. The guide rollers 35 of the arc-shaped parts 342 on both sides first contact the packaging box. Under the reaction force, the packaging box moves towards the middle. Then, when passing through the straight part 341, the guide rollers 35 on both sides can be moved towards the packaging box by the transverse drive device 4 and enter a state similar to clamping the packaging box. At this time, under the action of the conveyor 1, the packaging box can still move forward and the packaging box has been corrected. Then, the guide rollers 35 on both sides are removed by the transverse drive device 4, so that packaging boxes of different sizes can be corrected uniformly. In order to avoid excessive compression of the packaging box, a distance sensor is provided on the guide plate 34. The transverse drive device 4 is controlled by the information identified by the distance sensor through an existing mature controller. The specific circuit and control logic are existing mature technologies and are not the focus of this solution, so they will not be described in detail.
