Description

Technical Field

[0001] This invention relates to the field of optoelectronic display substrate processing technology, and in particular to a quick-change substrate carrier device for optoelectronic display manufacturing. Background Technology

[0002] In the precision lamination, bonding, and module manufacturing process of optoelectronic display substrates, the substrate support fixture is a core key piece of equipment that ensures the stability of substrate processing positioning, processing accuracy, and product yield. It directly determines the overall production quality of subsequent lamination processes and module assembly of optoelectronic substrates.

[0003] Currently, most traditional optoelectronic substrate support fixtures adopt a structure design that combines pure mechanical rigid support with manual bolt locking. When loading and placing the substrate, manual repositioning and calibration and individual bolt tightening are required. The substrate changeover and disassembly process is cumbersome and time-consuming, resulting in low efficiency. This cannot meet the production requirements of modern optoelectronic display production lines for rapid changeover and continuous batch processing. The traditional rigid bolt locking and rigid clamping structure has concentrated contact stress, which can easily cause damage such as edge crushing, corner breakage, indentation, and hidden cracks to the glass optoelectronic substrate, resulting in a high scrap rate. Furthermore, the rigid clamping structure cannot achieve buffering and adaptive yielding. During processing, equipment vibration and downward impact can easily cause slight offset and shaking of the substrate, resulting in poor positioning and alignment accuracy, which seriously affects the dimensional accuracy and process consistency of the substrate lamination process. Summary of the Invention

[0004] This invention provides a quick-change substrate carrier device for optoelectronic display manufacturing, which solves the problems of cumbersome substrate carrier fixture changes, low positioning accuracy, easy board damage, and poor protection effect.

[0007] As a further improvement of the present invention: the lifting assembly includes multiple top rods, two bases and two support plates. The ends of multiple transmission rods away from the piston plate are respectively hinged to one end of multiple top rods. The four top rods are connected in pairs and hinged together. The ends of the two sets of top rods are hinged to the inner walls of the two bases. One side of the two bases is respectively fixed to the bottom of the two support plates.

[0008] As a further improvement of the present invention: the lifting assembly further includes a storage trough, a buffer pad and two slots. The storage trough is opened on one side of the base and is used to receive the settled substrate for bottom support and positioning. The buffer pad is fixedly installed on the inner wall of the bottom of the storage trough. The two slots are symmetrically opened on one side of the storage trough, and two support plates are slidably disposed on the inner walls of the two slots respectively.

[0009] As a further improvement of the present invention: the substrate bearing centering clamping assembly includes two hollow cylinders, two pressure plates, two crossbars and two positioning plates. The two hollow cylinders are respectively fixedly disposed on both sides of the base. The two pressure plates are respectively movably embedded in the inner walls of the two hollow cylinders. One end of the two crossbars is respectively fixedly connected to the two pressure plates, and the other end of the two crossbars is respectively fixedly connected to the two positioning plates.

[0010] As a further improvement of the present invention: the substrate bearing centering clamping assembly further includes two second return springs and two rubber pads. The two second return springs are respectively movably sleeved on the outer surface of the two crossbars, and their two ends respectively abut against the inner wall of the hollow cylinder and one side of the pressure plate. The two rubber pads are respectively fixedly installed on the opposite side of the two positioning plates.

[0011] As a further improvement of the present invention: a first guide hose is installed on the outer surface of a plurality of first cylinders, the piston plate divides the inside of the cylinder into a front air chamber and a rear air chamber that are independent of each other, and the other end of the plurality of first guide hoses is connected to the front air chamber of the plurality of cylinders respectively, for conveying the compressed gas to the inside of the cylinder to drive the piston plate to move.

[0012] As a further improvement of the present invention: the cylinders are arranged in pairs, and the rear air chambers of the two sets of cylinders are interconnected by connecting pipes. The outer surfaces of the two connecting pipes are each equipped with a second guide hose, and the other ends of the two second guide hoses are respectively connected to one end of the two hollow cylinders, for collecting the pressurized gas at the rear of the cylinders and transporting it to the centering and clamping position to provide clamping power.

[0015] Compared with the prior art, the advantages and positive effects of the present invention are as follows: This invention uses a single cylinder pressing down as the sole power input for the entire device, eliminating the need for an external high-pressure air source, independent electrical control switches, and redundant auxiliary drive components. Through the pure mechanical-pneumatic integrated linkage of the pneumatic transmission linkage unit and the substrate bearing centering clamping assembly, multiple processes such as substrate lifting and quick-change loading, automatic sinking and positioning, and flexible automatic centering clamping on both sides can be completed simultaneously with a single pressing action. The actions are triggered synchronously, eliminating the need for manual step-by-step operation and precise pre-assembly, simplifying the substrate loading and unloading process. At the same time, the compressibility of gas itself enables flexible buffering of force and adaptive clamping and retraction throughout the process, completely abandoning the traditional rigid clamping and hard contact fixing method, and avoiding problems such as edge chipping, crushing, breakage, and hidden cracks that occur during the clamping and pressing of optoelectronic substrates.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Please see Figure 1 - Figure 8 This invention provides a quick-change substrate carrier device for optoelectronic display manufacturing, including a frame 1, a cylinder 101, a processing pressure box 102, and a pressing processing module 103. A pneumatic transmission linkage unit is provided on one side of the bottom of the frame 1. The pneumatic transmission linkage unit includes multiple first cylinders 3, multiple second cylinders 301, multiple buffer springs 302, and a base 303. The multiple first cylinders 3 are fixedly installed on the inner wall of the bottom of the frame 1, and the multiple second cylinders 301 are movably embedded in the inner wall of the multiple first cylinders 3. The multiple first cylinders 3 and the multiple second cylinders 301 are elastically connected by buffer springs 302. The top of the multiple second cylinders 301 is fixedly installed on the bottom of the base 303. A substrate carrier centering clamping assembly is provided on one side of the base 303. The substrate lifting and quick-change positioning is achieved through mechanical linkage of the pneumatic transmission linkage assembly.

[0027] In use, the operator first places the optoelectronic substrate to be processed directly on the upper part of the support plate 207. The support plate 207 is normally in a raised position, and the substrate can be quickly loaded and pre-assembled without the need for precise manual alignment. After the equipment is started, the cylinder 101 at the top of the frame 1 extends and drives the processing pressure box 102 and the internal pressing processing module 103 to press down simultaneously. The bottom of the processing pressure box 102 first contacts the extrusion base 303 and is subjected to downward force. The base 303 presses down and drives the second cylinder 301 to retract into the first cylinder 3 to compress the buffer spring 302, compressing the sealed air inside the first cylinder 3 to form a compressed air source. The compressed gas is delivered to the cylinder 201 through the first guide hose 304 to drive the piston plate 202 to move. The movement of the piston plate 202 drives the transmission rod 203 and the push rod 205 to move in conjunction.

[0028] like Figure 1 - Figure 8 As shown, in one embodiment, the pneumatic transmission linkage unit further includes two connecting plates 2, multiple cylinders 201, multiple piston plates 202, multiple transmission rods 203, multiple first return springs 204, and a lifting assembly. The two connecting plates 2 are symmetrically fixedly arranged at the bottom of the base 303. The multiple cylinders 201 are respectively fixedly arranged on opposite sides of the two connecting plates 2. The multiple piston plates 202 are respectively movably embedded in the inner wall of the multiple cylinders 201. One side of the multiple piston plates 202 is respectively fixedly arranged at one end of the multiple transmission rods 203. The multiple first return springs 204 are respectively fixedly arranged on one side of the multiple piston plates 202 and one side of the inner wall of the multiple cylinders 201. Through the hinged linkage transmission structure of multiple sets of top rods 205, the horizontal thrust of the piston plates 202 is converted into the vertical lifting and lowering pull of the support plate 207, realizing the smooth lifting and extension movement of the support plate 207, and completing the switching between the high-position feeding and low-position sinking processing positions of the substrate.

[0029] like Figure 1 - Figure 8 As shown, in one embodiment, the lifting assembly includes multiple push rods 205, two bases 206, and two support plates 207. The ends of multiple transmission rods 203 away from the piston plate 202 are respectively hinged to one end of the multiple push rods 205. The four push rods 205 are connected in pairs and are correspondingly hinged together. The ends of the two sets of push rods 205 are hinged to the inner walls of the two bases 206. One side of the two bases 206 is respectively fixed to the bottom of the two support plates 207. The piston plate 202 forms independent front and rear air chambers through a sealed sliding fit inside the cylinder 201. With the cooperation of the first return spring 204, the piston plate 202 is guided to move and automatically rebounds and resets after processing, ensuring stable and smooth mechanical transmission without jamming.

[0030] Furthermore, the lifting assembly also includes a storage trough 208, a buffer pad 209, and two slots 210. The storage trough 208 is located on one side of the base 303 and is used to receive the settled substrate and provide bottom support and positioning. The buffer pad 209 is fixedly installed on the inner wall of the bottom of the storage trough 208. The two slots 210 are symmetrically located on one side of the storage trough 208. Two support plates 207 are slidably disposed on the inner walls of the two slots 210. The slots 210 limit and guide the vertical sliding of the support plates 207. Together with the buffer pad 209, the bottom of the settled substrate is flexibly buffered and supported to avoid hard collision damage to the substrate and improve the stability of substrate processing and placement.

[0031] like Figure 1 - Figure 8 As shown, in one embodiment, the substrate bearing centering clamping assembly includes two hollow cylinders 4, two pressure plates 401, two crossbars 402, and two positioning plates 403. The two hollow cylinders 4 are respectively fixedly disposed on both sides of the base 303. The two pressure plates 401 are respectively movably embedded in the inner walls of the two hollow cylinders 4. One end of the two crossbars 402 is fixedly connected to the two pressure plates 401, and the other end of the two crossbars 402 is fixedly connected to the two positioning plates 403. The sealed air intake inside the hollow cylinders 4 pushes the pressure plates 401 to slide horizontally, causing the crossbars 402 and the positioning plates 403 to move synchronously relative to each other, thereby realizing the automatic centering, bonding, positioning, and clamping action of the two sides of the substrate.

[0032] Furthermore, the substrate bearing centering clamping assembly also includes two second return springs 405 and two rubber pads 404. The two second return springs 405 are respectively movably sleeved on the outer surface of the two crossbars 402, and their two ends respectively abut against the inner wall of the hollow cylinder 4 and one side of the pressure plate 401. The two rubber pads 404 are respectively fixedly installed on the opposite side of the two positioning plates 403. The second return springs 405 realize automatic rebound and release after clamping. The rubber pads 404 flexibly contact the side of the substrate to prevent the substrate from chipping, breaking, or being crushed and damaged due to rigid clamping, thus achieving a flexible buffer clamping protection effect.

[0033] like Figure 1 - Figure 8 As shown, in one embodiment, a plurality of first cylinders 3 are each equipped with a first guide hose 304 on their outer surfaces. The piston plate 202 divides the interior of the cylinder 201 into independent front and rear air chambers. The other ends of the plurality of first guide hoses 304 are respectively connected to the front air chambers of the plurality of cylinders 201 to deliver the compressed gas to the interior of the cylinder 201 to drive the piston plate 202 to move. Through the independent air chamber sealing guide structure, the precise air supply transmission of the compressed gas is realized, ensuring that the mechanical lifting action and the air pressure supply are synchronized and linked, without the need for an additional external air source and electrical control.

[0034] like Figure 1 - Figure 8 As shown, in one embodiment, multiple cylinders 201 are arranged in pairs, and the rear air chambers of the two sets of cylinders 201 are interconnected by connecting pipes 406. The outer surfaces of the two connecting pipes 406 are each equipped with a second guide hose 407. The other end of the two second guide hoses 407 is connected to one end of the two hollow cylinders 4 respectively, which is used to collect the pressurized gas on the rear side of the cylinders 201 and deliver it to the centering and clamping position to provide clamping power. The left and right sides of the base 303 are provided with sliding grooves 408. The two positioning plates 403 are slidably embedded in the inner walls of the two sliding grooves 408 respectively. The sliding grooves 408 precisely guide and limit the clamping and sliding of the positioning plates 403, ensuring that the two positioning plates 403 move synchronously and are accurately aligned without deviation or jamming.

[0035] like Figure 1 - Figure 8 As shown, in one embodiment, cylinder 101 is fixedly installed on one side of the top of frame 1, and the output end of cylinder 101 is fixedly connected to one side of processing pressure box 102. Pressing processing module 103 is fixedly installed on one side of the inner wall of processing pressure box 102. The single cylinder 101 presses down as the only power input of the whole device, driving the processing pressure box 102 and pressing processing module 103 to press down stably, providing the original pressing power for subsequent pneumatic linkage transmission, substrate sinking and positioning, and automatic centering and clamping.

[0036] Working principle: When in use, the substrate to be processed is first placed on the upper side of the two support plates 207. In the initial state, the support plates 207 are in a high position, which makes it easy to place the substrate directly without precise alignment, thus realizing fast loading and fast board changing. When processing the substrate, the output end of the cylinder 101 on the frame 1 drives the processing pressure box 102 to press down as a whole, and the pressing processing module 103 is pressed down accordingly. During the pressing process of the pressure box 102, it first contacts and presses down the base 303, applying pressure to the base 303, thereby causing multiple second cylinders 301 to slide into the inner wall of multiple first cylinders 3 simultaneously. While compressing the buffer spring 302, it squeezes the gas inside the first cylinder 3. The pressurized gas is delivered to the front position inside the four cylinders 201 through multiple first guide hoses 304 respectively. The piston plate 202 divides the inside of the cylinder 201 into two independent air chambers. After the air enters, the air pressure pushes the piston plate 202 to move directionally to the side away from the transmission rod 203. The movement of multiple piston plates 202 simultaneously pulls multiple transmission rods 203 to move. Then, through the hinged transmission of multiple top rods 205, it drives the two support plates 207 to move downward synchronously. The support plates 207 slide down and retract along the slot 210, causing the substrate placed on the support plates 207 to fall synchronously into the storage slot 208. The buffer pad 209 stably supports and positions the bottom of the substrate. While multiple piston plates 202 move backward for mechanical transmission, they simultaneously compress the gas in the rear air chamber inside the cylinder 201. The rear chambers of the two cylinders 201 on the same side are connected to each other through connecting pipes 406. The pressurized gas is transported through the two connecting pipes 406 and two second guide hoses 407 to the hollow cylinders 4 fixed on both sides of the base 303. After the gas enters the hollow cylinders 4, it pushes the two pressure plates 401 to slide relative to each other, causing the crossbar 402 and the positioning plate 403 to move synchronously towards each other. This allows the rubber pads 404 on the inner side of the positioning plates 403 on both sides to flexibly fit and clamp the left and right sides of the substrate, completing the automatic centering and lateral flexible limiting of the substrate. Then, the substrate can be stably processed by the pressing processing module 103. After processing, the cylinder 101 drives the processing pressure box 102 to move upward to release the pressure. Each spring rebounds and resets synchronously, the air pressure flows back to relieve the pressure, and the support plate 207 rises again to lift the substrate, completing a single processing cycle.

[0037] In summary, this invention uses the cylinder 101 as the sole power source, eliminating the need for additional electrical control switches, external air sources, and additional drive mechanisms. The entire system relies on a purely mechanical linkage combined with integrated pneumatic transmission to complete two core actions in a single pressing motion: the automatic placement of the substrate by the support plate 207 and the automatic centering and flexible clamping of the positioning plate 403 driven by pneumatic pressure. The process is interconnected and orderly, with synchronous triggering that eliminates the need for manual step-by-step operation. Furthermore, the compressibility of gas itself replaces the traditional purely mechanical rigid limit structure, allowing for flexible buffering and adaptive yielding during the pressing and clamping processes. This effectively avoids defects such as edge chipping, cracking, and breakage caused by rigid pressure, vibration, and start-stop inertia during substrate processing, significantly improving the yield rate of brittle substrates. At the same time, the support plate 207 is normally positioned at a high level, eliminating the need for precise alignment and locking of the substrate. After processing, the substrate is automatically lifted and unloaded, making loading, unloading, and removal convenient and enabling rapid substrate replacement.
