Description

Technical Field

[0001] The utility model relates to the technical field of liquid crystal screen production, and particularly refers to an equidistant conveyor line for liquid crystal screen production. Background Art

[0002] At present, in the automated production process of liquid crystal display modules, the stability and positioning accuracy of the blanking and conveying link directly affect the product yield; traditional conveyor lines generally adopt a roller conveying structure, which realizes the translation of materials by driving the rotation of a roller group by a motor. However, this method has the problem of offset caused by vibration. Specifically, the unevenness of the roller surface or the gap of the transmission mechanism is likely to cause periodic vibration, resulting in relative displacement between the glass and the housing. Especially for the installed liquid crystal display module, once the glass substrate installed on the housing is offset, it will affect subsequent processing and increase the defective rate. Summary of the Utility Model

[0003] The purpose of the utility model is to provide an equidistant conveyor line for liquid crystal screen production to overcome the deficiencies of the prior art.

[0004] To achieve the above purpose, the technical solution adopted by the utility model is: an equidistant conveyor line for liquid crystal screen production, comprising an equidistant conveying table, a plurality of blanking tables evenly spaced and arranged in a straight line on the equidistant conveying table, a slide rail assembly horizontally arranged on the equidistant conveying table and passing through a plurality of blanking tables, a plurality of lifting assemblies slidably arranged on the slide rail assembly and corresponding to the number and spacing of the blanking tables, a plurality of connecting rods horizontally placed for connecting adjacent lifting assemblies, and a linear module for driving one of the lifting assemblies to translate.

[0005] Avoidance grooves in a cross shape are arranged on each of the blanking tables.

[0006] The lifting assembly includes a sliding seat slidably arranged on the slide rail assembly, a lifting cylinder vertically arranged on the sliding seat, and a lifting plate horizontally arranged at the driving end of the lifting cylinder and in a cross shape.

[0007] Preferably, a plurality of evenly distributed vacuum suction cups are arranged on the lifting plate.

[0008] Preferably, positioning blocks are arranged at both ends of the lifting plate; the distance between the two positioning blocks is slightly larger than the size of the product.

[0009] Preferably, multiple pairs of threaded holes evenly spaced along the length direction of the lifting plate are respectively arranged at both ends of the lifting plate; through holes corresponding to any pair of threaded holes are respectively arranged at both ends of the positioning block; the positioning block is fixedly connected to the end of the lifting plate by bolts passing through the through holes and any pair of threaded holes.

[0010] Preferably, the through hole is elongated and placed along the length of the lifting plate; the length of the through hole is not less than the spacing between adjacent threaded holes.

[0011] Preferably, a guide frame is provided on the slide below the lifting plate; guide rods passing through the guide frame are respectively provided at both ends of the bottom of the lifting plate; the lifting cylinder is located between the two guide rods.

[0012] Preferably, the material unloading platform is equipped with a sensor for detecting whether there is a product.

[0013] Preferably, the slide rail assembly includes two horizontally and parallelly placed guide rails and a slider slidably disposed on the guide rails;

[0014] The linear module is positioned between two guide rails;

[0015] The bottom ends of the slide block are connected to the sliders on the two guide rails by the riser blocks, and the slide block is higher than the linear module.

[0016] Due to the application of the above technical solution, compared with the prior art, this utility model achieves the following significant beneficial effects through the coordinated design of the Feng-shaped clearance groove and the lifting component, as well as the linkage-type mechanical synchronization mechanism:

[0017] 1. Zero-vibration precision conveying: The lifting assembly completely lifts the outer shell off the unloading table through the lifting cylinder. During the translation process, the workpiece has zero contact with the conveying surface, which completely avoids the inherent vibration sources of roller conveyors (such as transmission chain vibration and uneven roller surface), ensuring that the glass installed on the outer shell has no risk of displacement and improving positional stability.

[0018] 2. Breakthrough in equidistant synchronization accuracy: The multi-lifting components are rigidly connected by connecting rods, and only a single linear module is needed to drive the synchronous translation of the entire workstation, resulting in small mechanical synchronization errors;

[0019] 3. Anti-deflection structure innovation: The "Feng" shaped lifting plate is embedded in the corresponding "Feng" shaped clearance groove on the unloading platform. During the lifting process, the longitudinal main groove and the transverse branch groove constrain the freedom of the shell displacement, preventing the workpiece from rotating horizontally or tilting to the side. It is especially suitable for the anti-tipping requirements of irregularly shaped glass shells. Attached Figure Description

[0026] The following further elaborates on the present utility model in conjunction with the attached drawings and specific embodiments.

[0027] Attached Figure 1-3 The equally spaced conveying line for liquid crystal screen production described in the present utility model includes an equally spaced conveying table 1, five blanking tables 2 evenly spaced and arranged in a straight line on the equally spaced conveying table 1, a slide rail assembly 3 horizontally arranged on the equally spaced conveying table 1 and passing through multiple blanking tables 2, five jacking components 4 slidably arranged on the slide rail assembly 3 and corresponding to the spacing of the blanking tables 2, four connecting rods 5 horizontally placed for connecting adjacent jacking components 4 respectively, and a linear module 6 for driving one of the jacking components 4 to translate;

[0028] The spacing between adjacent blanking tables 2 is greater than the overall length of the jacking component 4, and a cross-shaped avoidance groove 21 is provided on each blanking table 2;

[0029] The jacking component 4 includes a slide seat 41 slidably arranged on the slide rail assembly 3, a jacking cylinder 42 vertically arranged on the slide seat 41, and a cross-shaped jacking plate 43 horizontally arranged at the driving end of the jacking cylinder 42;

[0030] During operation: Since the five jacking components 4 are slidably arranged on the slide rail assembly 3 and connected by four connecting rods 5, they can be synchronously translated by the drive of the linear module 6, and under the drive of the blanking jacking cylinder 42, the outer shells on the blanking table 2 can be simultaneously lifted through the avoidance groove 21 by the jacking plate 43, moved to the next blanking table 2 and then simultaneously lowered, realizing equally spaced conveying. Compared with the existing roller conveying line, it not only has high precision but also smooth conveying, avoiding the deviation of the glass installed on the outer shell due to vibration during the conveying process.

[0031] Furthermore, as Figure 4As shown, the lifting plate 43 is provided with a plurality of evenly distributed vacuum suction cups 44; when the lifting plate 43 lifts the product 7 from the unloading table 2, the vacuum suction cups 44 can firmly adhere the product 7 to the lifting plate 43, so as to avoid the product 7 from shifting its position during the lifting or translation process and improve the conveying accuracy.

[0032] Furthermore, such as Figure 4 As shown, positioning blocks 45 are provided at both ends of the lifting plate 43; the distance between the two positioning blocks 45 is slightly larger than the size of the product 7; when the lifting plate 43 lifts the product 7 from the unloading table 2, the two positioning blocks 45 can position the product 7, further preventing the product 7 from shifting position during translation and ensuring conveying accuracy.

[0033] Furthermore, such as Figure 4 As shown, the lifting plate 43 has multiple pairs of threaded holes 431 evenly spaced along its length at both ends; the positioning block 45 has through holes 451 corresponding to any pair of threaded holes 431 at both ends; the positioning block 45 can be connected and fixed to the end of the lifting plate 43 by bolts passing through the through holes 451 and any pair of threaded holes 431; the through holes 451 are elongated and placed along the length of the lifting plate 43; the length of the through holes 451 is not less than the spacing between adjacent threaded holes 431; in this application, the positioning block 45 can be adjusted in two stages by cooperating with the threaded holes 431 through its elongated shape, whereby selecting different threaded holes 431 can achieve coarse adjustment, and the elongated shape can achieve fine adjustment within a small range, thereby adapting to products 7 of different sizes.

[0034] Furthermore, such as Figure 4 As shown, a guide frame 46 is provided on the slide block 41 below the lifting plate 43; guide rods 47 passing through the guide frame 46 are respectively provided at both ends of the bottom of the lifting plate 43; the lifting cylinder 42 is located between the two guide rods 47; by providing guide rods 47 at the bottom of the lifting plate, this application enables the lifting cylinder 42 to drive the lifting plate 43 to rise and fall, so that the rising and falling is more stable.

[0035] Furthermore, such as Figure 3 As shown, the unloading table 2 is equipped with a sensor 22 for detecting whether there is a product 7, which facilitates automated control; the sensor can be an optical sensor that does not contact the product 7, such as an infrared sensor; or it can be a contact sensor, such as a pressure sensor.

[0036] Furthermore, such as Figure 3 As shown, the slide rail assembly 3 includes two horizontally and parallelly placed guide rails 31 and a slider 32 slidably disposed on the guide rails 31;

[0037] The linear module 6 is positioned between two guide rails 31, which makes the force more even when the lifting assembly 4 is driven to move horizontally.

[0038] The bottom ends of the slide block 41 are connected to the sliders 32 on the two guide rails 31 via the riser blocks 48, and the slide block 41 is higher than the linear module 6.

[0039] The drive end of the linear module 6 is connected to the bottom of the slide 41 of one of the lifting components 4;

[0040] During operation: The linear module 6 drives the slide 41 of one of the lifting components 4 to translate. Under the action of the connecting rod, the five lifting components 4 are translated synchronously. At the same time, during the translation process, since the slide 41 is higher than the linear module 6, interference between the other lifting components 4 and the linear module 6 is avoided.

[0041] The above are merely specific application examples of this utility model and do not constitute any limitation on the scope of protection of this utility model. All technical solutions formed by equivalent transformations or equivalent substitutions fall within the scope of protection of this utility model.
