Description

Technical Field

[0001] This utility model belongs to the field of electronic glass substrate product packaging technology, and relates to a bearing tooling for improving the packaging accuracy of glass substrates. Background Technology

[0002] The current method of packaging glass substrates involves loading products into horizontal packaging boxes, which are then placed on a support station. Distance sensors are installed on the "right" and "back" sides of the support station. After the packaging box is placed on the support station, the distance sensors use infrared sensors to mark the end face of the packaging box support platform, measure the distance, and upload the measurement data to the robot's program. The robot automatically determines the position and corrects the placement of the substrate based on the data. However, since the placement position of the packaging box cannot be fixed, there are errors in the robot's measurement data. This situation leads to a certain probability of deviation in the placement accuracy at different positions, which does not meet the packaging process requirements. If manual inspection is required, it is necessary to enter the mechanical equipment, which poses a significant safety hazard. Utility Model Content

[0003] The purpose of this invention is to solve the technical problem of large errors in the placement of packaging boxes when packaging glass substrates in the prior art, and to provide a load-bearing tooling that improves the packaging accuracy of glass substrates.

[0004] In a first aspect, the present invention discloses a bearing fixture for improving the packaging accuracy of glass substrates, comprising an original bracket with a rear limiter, wherein telescopic cylinders are provided on both sides of the original bracket and on the front side opposite to the rear limiter; a plurality of distance sensors are provided on the original bracket; and the telescopic cylinders and distance sensors are all connected to a control system.

[0005] Further improvements are made in the following aspects: The telescopic cylinder includes two layers of telescopic cylinders arranged on the original bracket, with each layer having several telescopic cylinders.

[0006] The telescopic cylinder is bolted to the original bracket via its outer casing.

[0007] The distance sensor includes distance sensors respectively disposed on both sides and at the rear of the original bracket.

[0008] The control system is a PLC control system.

[0009] The piston rod of the telescopic cylinder is equipped with a roller at its free end.

[0010] The rollers are made of rubber.

[0011] The surface of the original bracket is provided with an antistatic coating, and the surface roughness of the antistatic coating is ≤0.8μm.

[0012] A pressure sensor is installed at the free end of the piston rod of the telescopic cylinder, and the pressure sensor is connected to the control system.

[0013] The distance sensor is a laser triangulation distance sensor.

[0014] Compared with the prior art, the present invention has the following beneficial effects: This utility model discloses a load-bearing fixture for improving the packaging accuracy of glass substrates. It utilizes telescopic cylinders on both sides and the front of the original bracket to form a three-way cooperative clamping structure, combined with a rear limiting device, to achieve omnidirectional position fixation of the horizontal packaging box, effectively solving the problem of placement deviation caused by box displacement in traditional fixtures. Multiple sets of distance sensors are linked with the cylinder control system to monitor changes in the packaging box's position in real time and dynamically adjust the cylinder extension and retraction, reducing the fluctuation range of sensor measurement data and significantly improving the reliability of position detection. The robotic arm's placement position is locked in spatial coordinates by the packaging box fixed by the cylinders.

[0015] Furthermore, by integrating cylinder action logic and sensor data streams through the PLC control system, the time for fixing and calibrating the packaging box is reduced to within 2 seconds, increasing the overall packaging cycle time by 40% and reducing the substrate breakage rate caused by positional errors. The upper and lower double-layer cylinder layout design supports compatible loading of packaging boxes of different thicknesses, and the roller structure reduces friction loss with the box body, making the tooling applicable to packaging containers with thicknesses ranging from 3-15mm.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings: Example 1 See Figure 1 This invention discloses a load-bearing fixture for improving the packaging accuracy of glass substrates. It is characterized by comprising an original bracket 1 with a rear limit 5, telescopic cylinders 2 on both sides and the front side opposite the rear limit 5 of the original bracket 1, the telescopic cylinders 2 being bolted to the original bracket 1 through their housings, and rollers made of rubber being provided at the free end of the piston rod of the telescopic cylinders 2; several distance sensors 3 are provided on the original bracket 1; and the telescopic cylinders 2 and the distance sensors 3 are connected to a control system, such as a PLC control system. By integrating the cylinder action logic and sensor data stream through the PLC control system, the time for fixing and calibrating the packaging box is shortened to within 2 seconds, increasing the overall packaging cycle time by 40%, while reducing the substrate breakage rate due to positional errors. The upper and lower double-layer cylinder layout design supports compatible loading of packaging boxes of different thicknesses, and the roller structure reduces frictional loss with the box, making the fixture applicable to packaging containers with thicknesses ranging from 3-15mm.

[0026] The telescopic cylinder 2 includes two layers of telescopic cylinders mounted on the original bracket 1, with each layer containing several telescopic cylinders. The distance sensor 3 includes distance sensors respectively mounted on both sides and at the rear of the original bracket 1. The surface of the original bracket 1 is coated with an antistatic coating with a surface roughness ≤0.8μm. A pressure sensor is mounted on the free end of the piston rod of the telescopic cylinder 2, and the pressure sensor is connected to the control system. The distance sensor 3 is a laser triangulation distance sensor.

[0027] This utility model discloses a load-bearing fixture for improving the packaging accuracy of glass substrates. It utilizes telescopic cylinders on both sides and the front of the original bracket to form a three-way cooperative clamping structure, combined with a rear limiting device, to achieve omnidirectional position fixation of the horizontal packaging box, effectively solving the problem of placement deviation caused by box displacement in traditional fixtures. Multiple sets of distance sensors are linked with the cylinder control system to monitor changes in the packaging box's position in real time and dynamically adjust the cylinder extension and retraction, reducing the fluctuation range of sensor measurement data and significantly improving the reliability of position detection. The robotic arm's placement position is locked in spatial coordinates by the packaging box fixed by the cylinders.

[0028] Example 2 This utility model embodiment includes an original bracket 1, a telescopic cylinder 2, and a distance sensor 3. The telescopic cylinder can fix the horizontal packaging box in the same position, and the distance sensor can correct and fine-tune it, avoiding the reduction of the plate placement accuracy caused by the processing size difference of the horizontal packaging box, and greatly optimizing the plate placement accuracy of the robot arm.

[0029] See Figure 1 The original bracket 1, which is the packaging box bearing station, has a large margin in the rear and left and right positions due to the large limit at the rear of the bracket. Therefore, the placement position of the packaging box cannot be fixed. The error of the placement plate is large after measuring the data by the distance sensor alone. Therefore, it is necessary to use a telescopic cylinder to fix the overall position of the packaging box. The telescopic cylinder 2 is a key improvement in this utility model. It is installed on the "left", "right", and "front" sides of the original bracket, with a total of 12 cylinders (considering the weight of the packaging box itself, the telescopic cylinders are arranged in two layers, with 6 cylinders per layer, and the contact position is the side skirt of the packaging box). The telescopic cylinders, along with the outer stainless steel shell, are bolted to the bracket. The telescopic movement of the cylinders is controlled by a PLC program, and the telescopic amount can be controlled manually. The telescopic shaft of the cylinder is connected to the outer rollers (the number of rollers can be customized), and the rollers are made of rubber, so they will not damage the box body during the process of pushing the packaging box. During initial use, the operator can adjust the telescopic amount of the cylinders themselves. After adjusting to the optimal position, the data can be saved in the PLC program. Subsequent use can be completed with one-button operation without the need to repeatedly set the telescopic cylinder data.

[0030] Distance sensors 3 are installed on the right side (1), left side (1), and rear (2) to detect the distance data of the horizontal packaging box support platform. The detected distance data is uploaded to the packaging robot's PLC program, and the packaging robot automatically positions the packaging box and corrects the placement of the plate. Although the packaging box is positioned by a telescopic cylinder, there are differences in the processing dimensions of the packaging box itself, so distance sensors are needed for fine-tuning and correction.

[0031] See Figure 2 For horizontal packaging boxes 4, the glass substrate must be placed on the support platform of the packaging box, and the packaging process requires that no corner of the glass substrate may extend beyond the edge of the support platform.

[0032] See Figure 3 The diagram shows the horizontal packaging box 4 placed at the support station. Personnel use a hand-operated hydraulic cart to place the packaging box at any position on the support platform. After placement, the left and right telescopic cylinders push the packaging box to a fixed position and lock it in the left and right directions.

[0033] See Figure 4 This diagram illustrates the placement of a horizontally packaged box at the support station. The telescopic cylinder at the "front" of the box pushes it until it is fully aligned with and locked against the limiting device at the rear support station. Once all cylinders are locked, the box is secured and the product can be collected.

[0034] The original horizontal packaging box placement position of the bearing station device was not fixed, and the distance sensor measurement data fluctuated greatly and had errors. The existing device adds a telescopic cylinder to fix the horizontal packaging box, and the robot arm places the plate in a fixed position, which greatly improves the plate placement accuracy.

[0035] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
