Description

Technical Field

[0001] The utility model relates to the technical field of liquid crystal screen panel production, and particularly refers to a feeding device for liquid crystal screen panel production. Background Art

[0002] With the rapid development of technology, liquid crystal screens, as the core components for information display, are increasingly widely used in fields such as smart phones, tablet computers, televisions, computer monitors, and in-vehicle displays, and the market demand continues to grow. However, in the production and manufacturing process of liquid crystal screen panels, the feeding link, as the starting point of the entire production process, its efficiency and automation level directly affect the overall efficiency and cost control of subsequent processing and assembly.

[0003] Currently, the production of liquid crystal screen panels generally adopts a combination of automation and semi-automation. However, in this basic and crucial step of feeding, there are still many challenges. Traditionally, liquid crystal glass substrates (i.e., the raw materials for liquid crystal screen panels) are stored in special cassettes in a stacked form. To prevent damage caused by mutual friction between the glasses, partition boards are carefully arranged between each layer of glass for separation. However, from this initial state to the formal processing on the production line, a series of preprocessing operations need to be carried out on each piece of glass, including but not limited to scanning codes (to record glass information such as batches, specifications, etc.), labeling (for easy tracking and management), and safely and accurately transporting the glass to the designated position on the production line (i.e., feeding).

[0004] Analysis of the current situation and problems:

[0005] 1. Strong dependence on manual labor: Currently, the above-mentioned preprocessing and feeding operations mainly rely on manual labor. Workers need to manually take out the glass from the cassette, scan the code and label each piece one by one, and carefully place the glass at the entrance of the automated or semi-automated production line. This highly manual labor-dependent method is not only inefficient, but also with the expansion of production scale, the demand for skilled workers increases sharply;

[0006] 2. High labor intensity and prone to errors: Liquid crystal glass substrates are usually heavy and have different sizes. Long-term manual operations cause a large physical burden on workers, and are prone to operation errors due to fatigue, such as glass breakage, wrong label pasting, etc., thus affecting product quality and production safety;

[0007] 3. Difficult recruitment and rising costs: With the changes in the labor market and the transformation of the employment concept of the younger generation, it is increasingly difficult to recruit workers with high skills and willing to engage in repetitive physical labor. This not only leads to an increase in labor costs, but also exacerbates production instability and supply chain risks;

[0008] 4. Low degree of automation: Although there are many highly automated devices and technologies in the entire production process of liquid crystal screen panels, the automation process in the feeding link is relatively lagging, becoming a bottleneck restricting the improvement of overall production efficiency.

[0058] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0059] Attached Figure 1-3 The feeding device for producing liquid crystal screen panels according to the present invention includes a machine platform 1, an automatic feeding mechanism 2, a first transfer manipulator 3, a calibration mechanism 4, a second transfer manipulator 5, a first translation and conveying mechanism 6, a scanning code mechanism 7, a third transfer manipulator 8, a second translation and conveying mechanism 9, and a labeling mechanism 10, which are respectively arranged on the machine platform 1;

[0060] The first transfer manipulator 3, the first translation and conveying mechanism 6 and the second translation and conveying mechanism 9 are placed in parallel; the second transfer manipulator 5 and the third transfer manipulator 8 are placed in parallel and are perpendicular to the first translation and conveying mechanism 6;

[0061] The automatic feeding mechanism 2 and the calibration mechanism 4 are located below the first transfer robot 3;

[0062] The calibration mechanism 4 and the first horizontal conveying mechanism 6 are located below the second transfer robot 5;

[0063] The first horizontal conveying mechanism 6 and the second horizontal conveying mechanism 9 are located below the third transfer robot 8;

[0064] The code scanning mechanism 7 straddles above the first horizontal conveying mechanism 6 and is located between the second transfer robot 5 and the third transfer robot 8;

[0065] The labeling mechanism 10 is arranged at one end of the second horizontal conveying mechanism 9;

[0066] During operation: The automatic feeding mechanism 2 automatically receives the materials from the existing feeding device or the AGV material vehicle; when the automatic feeding mechanism 2 receives the materials, the first transfer robot 3 automatically grabs the liquid crystal glass substrate 14 from the automatic feeding mechanism 2 and places it on the calibration mechanism 4 for calibration, then the second transfer robot 5 automatically places the calibrated liquid crystal glass substrate 14 on the calibration mechanism 4 on the first horizontal conveying mechanism 6, and then the first horizontal conveying mechanism 6 automatically places the calibrated liquid crystal glass substrate 14 on the code scanning mechanism 7 for code scanning first, and then sends it to the third transfer robot 8, and then the third transfer robot 8 automatically places the code-scanned liquid crystal glass substrate 14 on the second horizontal conveying mechanism 9, and finally the second horizontal conveying mechanism 9 automatically places the code-scanned liquid crystal glass substrate 14 on the labeling mechanism 10 for labeling first, and finally sends it to the loading waiting station, completing the pre-treatment work such as calibration, code scanning and labeling before loading. The degree of automation is high, which not only greatly improves the loading efficiency, but also reduces the labor cost and error rate.

[0067] Further, as Figure 1 and Figure 4 shown, the automatic feeding mechanism 2 includes a feeding station 21 and a recycling station 22 arranged side by side, and conveyor lines 23 respectively arranged on the feeding station 21 and the recycling station 22; among them, the material box 13 storing the liquid crystal glass substrate 14 will be conveyed to the conveyor line 23 of the feeding station 21, and the empty material box 13 will flow out through the conveyor line 23 of the recycling station 22; the conveying direction of the conveyor line 23 is perpendicular to the first transfer robot 3; the recycling station 22 and the calibration mechanism 4 are located on both sides of the feeding station 21;

[0068] As Figure 6As shown in the figure, the first transfer robot 3 includes a first transfer bracket 31, a double-slide single-drive linear module 32 horizontally arranged, first lifting modules vertically arranged on the double-drive ends of the double-slide single-drive linear module 32 respectively, a first vacuum suction nozzle assembly A36 and a first vacuum suction nozzle assembly B34 arranged on the drive ends of the two first lifting modules respectively; a clamping jaw assembly 37 for grasping empty boxes is further arranged on the first vacuum suction nozzle assembly A36;

[0069] At the initial position: The first vacuum suction nozzle assembly A36 and the first vacuum suction nozzle assembly B34 are respectively located directly above the recycling station 22 and the feeding station 21;

[0070] When the feeding station 21 receives the incoming material, the first lifting module B33 drives the first vacuum suction nozzle assembly B34 to descend to suck the liquid crystal glass substrate 14 from the material box 13 and rise back to the initial position; then the double-slide single-drive linear module 32 simultaneously drives the two first lifting modules to translate to the right until the first vacuum suction nozzle assembly A36 and the first vacuum suction nozzle assembly B34 are respectively located directly above the feeding station 21 and the calibration mechanism 4. Then the first lifting module B33 drives the first vacuum suction nozzle assembly B34 to descend and place the liquid crystal glass substrate 14 on the calibration mechanism 4. At the same time, the first lifting module A35 drives the first vacuum suction nozzle assembly A36 to descend to suck the partition from the material box 13; when the first vacuum suction nozzle assembly A36 and the first vacuum suction nozzle assembly B34 both rise back to the initial position, the double-slide single-drive linear module 32 simultaneously drives the two first lifting modules to translate to the left back to the initial position; then the first lifting module B33 continues to drive the first vacuum suction nozzle assembly B34 to descend to suck the liquid crystal glass substrate 14 from the material box 13, and at the same time, the first lifting module A35 drives the first vacuum suction nozzle assembly A36 to descend and place the partition into the empty material box 13 on the conveyor line 23 of the recycling station 22; when the first vacuum suction nozzle assembly A36 and the first vacuum suction nozzle assembly B34 both rise back to the initial position, the double-slide single-drive linear module 32 continues to drive the two first lifting modules to translate to the right simultaneously, and cycles in turn until all the multiple liquid crystal glass substrates 14 stacked in the material box 13 on the conveyor line of the feeding station 21 are taken out; at this time, the conveyor line 23 of the recycling station 22 first flows the material box 13 containing the partition to the existing feeding device or the AGV material vehicle, and the first vacuum suction nozzle assembly A36 is just located directly above the feeding station 21. Since the clamping jaw assembly 37 is arranged on the first vacuum suction nozzle assembly A36, under the drive of the double-slide single-drive linear module 32 and the first lifting module A35, the empty box is grasped from the feeding station 21 by the clamping jaw assembly 37 and placed on the recycling station 22. Finally, the feeding station 21 continues to receive the incoming material from the existing feeding device or the AGV material vehicle and continues to cycle the above work.

[0071] Further, as Figure 7As shown, the gripper assembly 37 includes gripper cylinders 371 respectively arranged on both sides of the first vacuum suction nozzle assembly A36, and grippers 372 respectively arranged at the driving ends of the two gripper cylinders 371 for grasping empty boxes.

[0072] Furthermore, as Figure 4-5 shown, the conveyor lines 23 at the feeding station 21 and the recycling station 22 both adopt rolling conveyor lines; positioning components 24 for positioning the material boxes 13 are arranged on the rolling conveyor lines;

[0073] The positioning components 24 include a tail crotch 241 arranged at the end of the rolling conveyor line, positioning plates 242 respectively arranged on both sides of the rolling conveyor line, a movable frame 243 slidably arranged at the bottom of the rolling conveyor line, a plurality of connecting pieces 244 located between adjacent rollers for connecting the positioning plates 242 and the movable frame 243, and a cylinder group 245 arranged at the bottom of the rolling conveyor line for driving the movable frame 243 to make the two positioning plates 242 approach or move away synchronously;

[0074] After a material box 13 is placed on the rolling conveyor line, the rolling conveyor line first drives the material box 13 to move towards the end, positions it through the tail crotch 241, and then simultaneously drives the two movable frames 243 by the cylinder group 245 to drive the positioning plates 242 on both sides to clamp the material box 13, facilitating the first transfer manipulator 3 to grasp the liquid crystal glass substrate 14 or place the partition plate.

[0075] Furthermore, as Figure 3-4 shown, the feeding station 21 and the recycling station 22 are also provided with a feeding lifting component 25 for driving the conveyor line 23 to lift; a hollow part 16 facilitating the lifting of the conveyor lines at the feeding station 21 and the recycling station 22 is arranged on the side of the machine table 1; by setting the above structure in the present utility model, it is convenient to dock with the existing feeding device or AGV material vehicle to realize material receiving and feeding.

[0076] Furthermore, as Figure 4 shown, the feeding lifting component 25 includes a square bracket 251, guide rail components 252 respectively vertically arranged on both sides of the square bracket 251, a lifting frame 253 slidably arranged on the two guide rail components 252, a lead screw 254 vertically arranged on the square bracket 251 and located between the two guide rail components 252 for driving the lifting frame 253 to lift, and a servo drive module 255 arranged at the bottom of the square bracket 251 for driving the lead screw 254; the conveyor line 23 is horizontally arranged on the lifting frame 253;

[0077] When the feeding station 21 needs to receive materials or the recycling station 22 needs to send materials, the servo drive module 255 drives the lead screw 254 to drive the lifting frame 253 to descend until the conveyor line 23 is at the same height as the existing feeding device or the AGV material vehicle. At this time, the existing feeding device or the AGV material vehicle transports the material box 13 storing the liquid crystal glass substrate 14 onto the conveyor line 23 at the feeding station 21, or the conveyor line 23 at the recycling station 22 transports the material box 13 with partitions placed thereon to the existing feeding device or the AGV material vehicle.

[0078] Further, as Figure 8 shown, the calibration mechanism 4 includes a calibration table 41, a calibration station 42 provided on the calibration table 41 that can adsorb the liquid crystal glass substrate 14, an X-axis calibration component 43 for calibrating the liquid crystal glass substrate 14 in the X-axis direction on the calibration station 42, and a Y-axis calibration component 44 for calibrating the liquid crystal glass substrate 14 in the Y-axis direction on the calibration station 42;

[0079] After the first transfer manipulator 3 grabs the liquid crystal glass substrate 14 from the feeding station 21 and places it on the calibration station 42, the calibration station 42 first adsorbs the liquid crystal glass substrate 14, and then performs position calibration through the X-axis calibration component 43 and the Y-axis calibration component 44 respectively, thereby improving the feeding accuracy.

[0080] Further, as Figure 9 shown, the X-axis calibration component 43 and the Y-axis calibration component 44 are arranged below the calibration table 41 and are placed in a crosswise manner. They both include a calibration base 441, two guide rail components 442 arranged in parallel on the calibration base 441, two main sliders 443 slidably arranged on the two guide rail components 442, a double-headed lead screw 444 arranged on the calibration base 441 and located between the two guide rail components 442 for driving the two main sliders 443 to approach or move away synchronously, a servo drive module 445 for driving the double-headed lead screw 444 to rotate, and calibration columns 446 vertically arranged on the main sliders 443 and located around the calibration station 42;

[0081] In the initial state: the calibration columns 446 around the calibration station 42 are in an open state;

[0082] After the calibration station 42 adsorbs the liquid crystal glass substrate 14, the servo drive module 445 of the X-axis calibration component 43 and the Y-axis calibration component 44 drives the double-headed lead screw 444 to rotate, so that the two main sliders 443 drive the calibration columns 446 to approach simultaneously, and perform position calibration on the liquid crystal glass substrate 14 on the calibration station 42.

[0083] Further, as Figure 8 shown, there are two calibration columns 446 on each side of the calibration station 42, which can effectively prevent the liquid crystal glass substrate 14 from tilting.

[0084] Furthermore, as Figure 9 shown, the double-headed threaded lead screw 444 can be a single lead screw with opposite helix directions at both ends, or it can be two lead screws with opposite helix directions connected by a coupling.

[0085] Furthermore, the servo drive modules in the feeding lifting assembly 25, the X-axis calibration assembly 43, and the Y-axis calibration assembly 44 can directly use servo motors, or can use the structure of a servo motor and a belt drive.

[0086] Furthermore, as Figure 11 shown, the second transfer manipulator 5 and the third transfer manipulator 8 are the same, and both include a transfer gantry 51, an X-axis linear module 52 group horizontally arranged on the transfer gantry 51, a second lifting module 53 vertically arranged on the driving end of the X-axis linear module 52 group, and a second vacuum suction nozzle assembly 54 arranged on the driving end of the second lifting module 53;

[0087] During operation: Driven by the X-axis linear module 52 group and the second lifting module 53, the corrected liquid crystal glass substrate 14 is placed on the first translation conveying mechanism 6 by using the second vacuum suction nozzle assembly 54, or the scanned liquid crystal glass substrate 14 is placed on the second translation conveying mechanism 9.

[0088] Furthermore, the first lifting module and the second lifting module 53 can adopt the driving method of a servo electric cylinder, or can use the driving method of a cylinder.

[0089] Furthermore, as Figure 12 shown, the first translation conveying mechanism 6 and the second translation conveying mechanism 9 have the same structure, and both include a servo sliding table module 61, a translation table 62 horizontally arranged on the driving end of the servo sliding table module 61, and a translation station 63 arranged on the translation table 62 that can adsorb the liquid crystal glass substrate 14;

[0090] During operation: First, the liquid crystal glass substrate 14 is adsorbed by the translation station 63, and then the translation table 62 is driven by the servo sliding table module 61 to drive the liquid crystal glass substrate 14 to translate, completing the scanning or labeling process.

[0091] Furthermore, as Figure 14 shown, the second translation conveying mechanism 9 further includes an extended translation component 91 arranged on the driving end of the servo sliding table module 61 for driving the translation table 62 to move vertically;

[0092] During operation: The translation table 62 can be driven by the extended translation component 91 to translate a certain distance outside the machine table 1, facilitating the docking with the existing liquid crystal screen panel production equipment.

[0093] Furthermore, the extended translation component 91 can be a servo linear module or a cylinder module.

[0094] Further, as shown in Figure 8 and Figure 12 , sensors 12 for detecting whether there is material feeding are provided on both the calibration station 42 and the translation station 63.

[0095] Further, as shown in Figure 13 , the code scanning mechanism 7 includes a code scanning gantry 71, an X-axis linear module 72 horizontally arranged on the code scanning gantry 71, and a vision component 73 vertically arranged on the driving end of the X-axis linear module 72;

[0096] After the first translation and conveying mechanism 6 drives the liquid crystal glass substrate 14 to be placed below the code scanning mechanism 7, the vision component 73 is driven by the X-axis linear module 72 to perform scanning, which is convenient for recording glass information such as batch, specification, etc.

[0097] Further, as shown in Figure 15 , the labeling mechanism 10 includes a printer (not shown in the figure), an XYZ three-axis linear module 101 arranged at the outlet of the printer, and a label vacuum suction nozzle 102 vertically arranged at the driving end of the XYZ three-axis linear module 101;

[0098] After the third transfer robot 8 places the code-scanned liquid crystal glass substrate 14 on the second translation and conveying mechanism 9, the position of the liquid crystal glass substrate 14 is exactly at the labeling station at this time. Then, the XYZ three-axis linear module 101 drives the label vacuum suction nozzle 102 to suck the label from the printer and stick it on the set position of the liquid crystal glass substrate 14.

[0099] Embodiment 2:

[0100] As shown in Figure 1-15 , on the basis of Embodiment 1, in order to further improve the production efficiency, the feeding station 21 and the recycling station 22 of the automatic feeding mechanism 2 can store two material boxes 13 at a time. At the same time, the calibration mechanism 4, the first translation and conveying mechanism 6, and the second translation and conveying mechanism 9 all adopt double stations, and the first transfer robot 3, the second transfer robot 5, and the third transfer robot 8 can suck two liquid crystal glass substrates 14 at a time;

[0101] The two material boxes 13 stored on the feeding station 21 and the recycling station 22 are placed along the vertical direction of the first transfer robot 3; the two stations of the first translation and conveying mechanism 6 and the second translation and conveying mechanism 9 are symmetrically arranged along the conveying direction;

[0102] As shown in Figure 4-5As shown, the positioning assembly 24 further includes a middle baffle 246 vertically arranged between two adjacent rollers in the middle of the roller conveyor line, and a lifting cylinder 247 vertically arranged at the bottom of the roller conveyor line for driving the middle baffle 246 to lift. During operation: when the first cartridge 13 is positioned by the tail baffle, the lifting cylinder 247 will drive the middle baffle 246 to rise to position the second cartridge 13.

[0103] Since the calibration mechanism 4 adopts a dual-station design, a pair of calibration columns 446 in the X-axis direction cannot simultaneously perform position calibration on two liquid crystal glass substrates 14, as Figure 8-10 shown. Therefore, two slave sliders 431 are slidably arranged at the bottom of the calibration table 41 of the X-axis calibration assembly 43; both of the slave sliders 431 are connected to the main slider 443 through a connecting rod 432 passing through the other slave slider 431; an inner calibration column 433 protruding from the tabletop of the calibration table 41 is arranged on the slave slider 431.

[0104] When the X-axis calibration assembly 43 is working: the servo drive module 445 drives the double-headed threaded lead screw 444 to rotate, so that the two main sliders 443 drive the calibration columns 446 to approach simultaneously. Since the two slave sliders 431 are connected to the respective opposite main sliders 443 through the connecting rod 432, the two slave sliders 431 move away simultaneously, realizing dual-station calibration, which has the advantages of compact structure and synchronous movement.

[0105] Embodiment Three:

[0106] As Figure 16 shown, on the basis of Embodiment Two, it further includes a manual feeding mechanism 11 arranged on the machine table 1 and at one end of the first translation conveying mechanism 6.

[0107] The manual feeding mechanism 11 includes a material table 111 slidably arranged on the machine table 1, a translation cylinder 112 arranged on the machine table 1 for driving the material table 111 to approach or move away from the first translation conveying mechanism 6, an XYZ three-axis linear module 113 arranged above the material table 111, and a third vacuum suction nozzle assembly 114 vertically arranged at the driving end of the XYZ three-axis linear module 113.

[0108] The material table 111 is provided with a loading station and an unloading station; the loading station is used for stacking and storing the trays 15 with liquid crystal glass substrates 14, and the unloading station is used for stacking empty trays 15.

[0109] The XYZ three-axis linear module 113 is used to drive the third vacuum suction nozzle assembly 114 to suck the liquid crystal glass substrate 14 from the tray 15 at the loading station and place it on the first translation conveying mechanism 6, and at the same time place the empty tray 15 from the loading station at the unloading station.

[0110] For some small or a small number of liquid crystal glass substrates 14, they can be placed in the tray 15. During operation: The staff places the stacked material boxes 13 at the loading station, and then the translation cylinder 112 drives the material table 111 to move to the end of the first translation conveying mechanism 6. Then, the XYZ three-axis linear module 113 drives the third vacuum suction nozzle assembly 114 to suck the liquid crystal glass substrate 14 from the tray 15 at the loading station and place it on the first translation conveying mechanism 6. If barcode scanning is required, it is driven to the barcode scanning mechanism 7 by the first translation conveying mechanism 6 for barcode scanning, and then returns to below the third transfer manipulator 8. The barcode-scanned liquid crystal glass substrate 14 is placed on the second translation conveying mechanism 9 by the third transfer manipulator 8 to continue the subsequent labeling process; if barcode scanning is not required, the liquid crystal glass substrate 14 is directly placed on the second translation conveying mechanism 9 by the third transfer manipulator 8 to continue the subsequent labeling process; when the liquid crystal glass substrate 14 in the uppermost tray 15 at the loading station is taken out, the XYZ three-axis linear module 113 drives the third vacuum suction nozzle assembly 114 to place the empty tray 15 at the uppermost layer of the loading station at the unloading station and continue loading until all the liquid crystal glass substrates 14 in the tray 15 at the loading station are taken out. At this time, the translation cylinder 112 drives the material table 111 to move to the edge of the machine table 1 and gives an alarm reminder, facilitating manual removal of the empty tray 15 from the unloading station and replenishing the tray 15 with liquid crystal glass substrates 14 at the loading station.

[0111] The above is only a specific application example of the present invention, and does not constitute any limitation to the protection scope of the present invention. Any technical solutions formed by equivalent transformation or equivalent substitution fall within the scope of the protection of the present invention.
