Description

Technical Field

[0001] The invention relates to the technical field of liquid crystal glass processing, in particular to a slide mechanism capable of adjusting the distance between slide plates online and an anti-eccentric wear traction roller device. Background Art

[0002] During the LCD glass substrate forming process, fixed and floating traction rollers are used to clamp the substrates within a high-temperature annealing furnace. These rollers are mounted on the fixed and floating ends of the slide mechanism via a pair of parallel long rollers. The floating end of the slide applies pressure to the fixed end through a counterweight linkage mechanism. The floating end of the slide mechanism slides along the cross-guide rails of the slide mechanism via a slide plate. A gap exists between the cross-guide rails and the retaining frame. However, due to the cantilever effect of the long rollers, the fixed and floating ends of the slide mechanism are subjected to force, which in turn applies force to the cross-guide rails and retaining frame. However, these forces can cause slight wear and deformation on the cross-guide rails and retaining frame, leading to deformation of the slide mechanism and changes in the spacing between the slide plates. Ultimately, the long rollers mounted at the front are no longer parallel, resulting in inconsistent wear on the fixed and floating traction rollers and uneven wear, resulting in uneven wear.

[0003] However, during routine maintenance work, the long roller needs to be withdrawn from the annealing furnace. At this time, the counterweight connecting rod must be opened, so personnel cannot measure and adjust the slide mechanism. Only when the process is in normal production will the counterweight connecting rod exert pressure on the slide. At this time, the long roller extends into the high-temperature furnace body and the slide mechanism is near the furnace body. Therefore, under the influence of high temperature, the deformation of the slide cannot be measured and adjusted. Summary of the Invention

[0009] Preferably, a threshold value is preset in the controller;

[0025] 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.

[0026] Reference Figure 1 The present invention proposes a slide mechanism capable of adjusting the distance between slides online, comprising: a base plate 1, a first slide 5, a second slide 6 and a controller 7;

[0027] The base plate 1 is symmetrically provided with a first support plate 2 and a second support plate 3 at both ends in the first horizontal direction. Guide rail mounting grooves are provided on opposite sides of the first support plate 2 and the second support plate 3. A cross ball guide rail 4 is installed in each guide rail mounting groove.

[0028] A first slide 5 and a second slide 6 are installed on the base plate 1 in parallel and spaced apart along a second horizontal direction perpendicular to the first horizontal direction. The first slide 5 is fixedly connected to the base plate 1. Both ends of the second slide 6 in the first horizontal direction are slidably connected to the cross ball guide 4. The second slide 6 is connected to a counterweight connecting rod mechanism. A first distance sensor is installed between the first end of the first slide 5 and the first end of the second slide 6. A second distance sensor is installed between the second end of the first slide 5 and the second end of the second slide 6.

[0029] The second support plate 3 is provided with a plurality of through holes spaced and evenly spaced along the second horizontal direction. The through holes penetrate the second support plate 3 along the first horizontal direction, and each through hole is connected to the guide rail mounting groove. A supporting rod for abutting against the cross ball guide rail 4 is slidably connected in each through hole, and each supporting rod is connected to a driving mechanism.

[0030] The first distance sensor, the second distance sensor and the driving mechanism are respectively connected to the controller 7;

[0031] The first distance sensor is used to measure a first distance between the first end of the first slide 5 and the first end of the second slide 6; the second distance sensor is used to measure a second distance between the second end of the first slide 5 and the second end of the second slide 6; the controller 7 is used to control multiple driving mechanisms to coordinate actions according to the first distance and the second distance to adjust the distance between the first slide 5 and the second slide 6.

[0032] The present invention can perform online detection of the deformation of the first slide 5 and the second slide 6 of the slide mechanism through the first distance sensor and the second distance sensor during the production of liquid crystal glass, and control multiple driving mechanisms to perform coordinated actions online in real time to adjust the distance between the first slide 5 and the second slide 6 according to the first distance between the first end of the first slide 5 and the first end of the second slide 6, thereby avoiding changes in the distance between the first slide 5 and the second slide 6, thereby avoiding the problem of eccentric wear caused by inconsistent wear of the fixed traction roller and the floating traction roller due to misalignment of a pair of long rollers installed at the front ends of the first slide 5 and the second slide 6, thereby ensuring the stability of the liquid crystal glass substrate forming process.

[0033] In order to adjust the distance between the first slide 5 and the second slide 6, in one specific embodiment, the number of through holes is five and the number of driving mechanisms is also five.

[0034] The five driving mechanisms in the second horizontal direction are a first driving mechanism, a second driving mechanism, a third driving mechanism, a fourth driving mechanism and a fifth driving mechanism;

[0035] A threshold is preset in the controller 7. When the difference between the first spacing and the second spacing exceeds the threshold, the controller 7 determines the deformation amount and deformation direction of the slide mechanism based on the positive or negative value of the difference between the first spacing and the second spacing, and gives signals to the first drive mechanism, the second drive mechanism, the third drive mechanism, the fourth drive mechanism and the fifth drive mechanism respectively, and adjusts the abutment pressure applied by each abutment link driven by the first drive mechanism, the second drive mechanism, the third drive mechanism, the fourth drive mechanism and the fifth drive mechanism on the cross ball guide rail 4.

[0036] In a further embodiment, when the difference between the first spacing and the second spacing is less than the threshold value X, the controller 7 gives a signal indicating the current status of the first drive mechanism, the second drive mechanism, the third drive mechanism, the fourth drive mechanism, and the fifth drive mechanism, and the automatic adjustment ends;

[0037] When the difference between the first spacing and the second spacing is greater than the threshold value X, and the first spacing is greater than the second spacing, the controller 7 determines that the slide mechanism has undergone an outward eight deformation; when it is determined that the slide mechanism has undergone an outward eight deformation, the controller 7 gives the first drive mechanism, the second drive mechanism, the fourth drive mechanism and the fifth drive mechanism a signal to increase the active stroke and gives the third drive mechanism a signal to reduce the active stroke; the first drive mechanism, the second drive mechanism, the fourth drive mechanism and the fifth drive mechanism increase the active stroke according to the received signal, so that the abutting pressure of the abutting connecting rod connected to the first drive mechanism, the second drive mechanism, the fourth drive mechanism and the fifth drive mechanism on the cross ball guide rail increases; the third drive mechanism reduces the active stroke according to the received signal, so that the abutting pressure of the abutting connecting rod connected to the third drive mechanism on the cross ball guide rail is reduced, thereby applying pressure to the cross ball guide rail 4 to resist the deformation force;

[0038] When the difference between the first spacing and the second spacing is greater than the threshold value X, and the first spacing is smaller than the second spacing, the controller 7 determines that the slide mechanism has undergone an inward-facing deformation; when it is determined that the slide mechanism has undergone an inward-facing deformation, the controller 7 gives the first drive mechanism, the second drive mechanism, the fourth drive mechanism and the fifth drive mechanism a signal to reduce the active stroke and gives the third drive mechanism a signal to increase the active stroke; the first drive mechanism, the second drive mechanism, the fourth drive mechanism and the fifth drive mechanism reduce the active stroke according to the received signal, so that the abutment pressure of the abutment connecting rod connected to the first drive mechanism, the second drive mechanism, the fourth drive mechanism and the fifth drive mechanism on the cross ball guide rail is reduced; the third drive mechanism increases the active stroke according to the received signal, so that the abutment pressure of the abutment connecting rod connected to the third drive mechanism on the cross ball guide rail is increased, thereby applying pressure to the cross ball guide rail 4 to counteract the deformation force.

[0039] Of course, in a specific embodiment, the number of driving mechanisms may also be other, such as 3 or 7.

[0040] In other embodiments, the number of driving mechanisms may also be another even number, and the two driving mechanisms in the middle may be regarded as one driving mechanism to operate.

[0041] Reference Figure 2 and Figure 3 In this embodiment, the driving mechanism is a cylinder, and the five driving mechanisms are respectively the first cylinder 8, the second cylinder 9, the third cylinder 10, the fourth cylinder 11 and the fifth cylinder 12. The front end of the piston rod of the cylinder is coaxially fixed with the corresponding abutting connecting rod, and each cylinder is connected to an electric damper actuator, namely the first electric damper actuator, the second electric damper actuator, the third electric damper actuator, the fourth electric damper actuator and the fifth electric damper actuator.

[0042] During the specific operation of this embodiment, a threshold is preset in the controller 7. When the difference between the first spacing and the second spacing exceeds the threshold, the controller 7 determines the deformation amount and deformation direction of the slide mechanism according to the positive or negative difference between the first spacing and the second spacing, and gives signals to the first electric air valve actuator, the second electric air valve actuator, the third electric air valve actuator, the fourth electric air valve actuator and the fifth electric air valve actuator respectively, and adjusts the air intake volume of the first cylinder 8, the second cylinder 9, the third cylinder 10, the fourth cylinder 11 and the fifth cylinder 12, thereby adjusting the pressure of each cylinder, thereby adjusting the abutment pressure applied by each abutment link connected to each cylinder to the cross ball guide rail 4.

[0043] When the difference between the first spacing and the second spacing is less than the threshold value X, the controller 7 sends a signal to the first electric damper actuator, the second electric damper actuator, the third electric damper actuator, the fourth electric damper actuator, and the fifth electric damper actuator to maintain the current airflow size, and the pressure of the first cylinder 8, the second cylinder 9, the third cylinder 10, the fourth cylinder 11, and the fifth cylinder 12 is maintained, and the automatic adjustment ends;

[0044] like Figure 2 As shown, when the difference between the first spacing and the second spacing is greater than the threshold value X, and the first spacing is greater than the second spacing, the controller 7 determines that the slide mechanism has undergone an outward eight deformation. At this time, the controller 7 sends a signal to the first electric damper actuator, the second electric damper actuator, the fourth electric damper actuator, and the fifth electric damper actuator to increase the airflow, and sends a signal to the third electric damper actuator to reduce the airflow. The pressure of the first cylinder 8, the second cylinder 9, the fourth cylinder 11, and the fifth cylinder 12 increases, and the pressure of the third cylinder decreases, thereby applying pressure to the cross ball guide 4 to resist the deformation force;

[0045] like Figure 3 As shown, when the difference between the first spacing and the second spacing is greater than the threshold value X, and the first spacing is smaller than the second spacing, the controller 7 determines that the slide mechanism has undergone an inward eight deformation, and the controller 7 gives the first electric air valve actuator, the second electric air valve actuator, the fourth electric air valve actuator and the fifth electric air valve a signal to reduce the airflow, and gives the third electric air valve actuator a signal to increase the airflow, the pressure of the first cylinder 8, the second cylinder 9, the fourth cylinder 11 and the fifth cylinder 12 decreases, and the pressure of the third cylinder increases, thereby applying pressure to the cross ball guide rail 4 to counteract the deformation force.

[0046] In other embodiments, the driving mechanism may also be other driving mechanisms such as an electric push rod, a cam connecting rod, etc.

[0047] In this embodiment, both the first distance sensor and the second distance sensor are high-precision contact digital sensors.

[0048] In this embodiment, a linear guide rail is further included and arranged along the second horizontal direction, and the bottom of the base plate 1 is slidably connected to the linear guide rail.

[0049] like Figure 4 As shown, the present invention also proposes an anti-biased wear traction roller device, including any one of the above-mentioned slide mechanisms capable of online adjusting the distance between slide plates.

[0050] In this embodiment, since the anti-biased wear traction roller device includes the slide mechanism structure of the calcining machine with the slide spacing adjustable online as described in any of the above embodiments, it has all the beneficial effects of the slide mechanism with the slide spacing adjustable online, which will not be described in detail here.

[0051] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
