Description

Technical Field

[0001] The present invention belongs to the field of display panel production, and more specifically, relates to a carrier logistics transfer device and a transfer method. Background Art

[0002] During the production process of display panels, finished product inspection is a critical step in ensuring product quality. This is especially true for display panel equipment. This often requires placing the display panel on a test bench, connecting the screen's conductive terminals to the equipment's test terminals, powering the screen, switching the display, capturing an image with a camera, and processing the image with an algorithm to obtain the test results. After the test is complete, the terminals are manually disconnected, the product is removed, and marked as conforming. This process is repeated before testing the next panel, taking approximately three minutes to complete.

[0003] In the above test links, a key step is to efficiently place the display panel on the test carrier. This process involves the logistics transfer of the display panel. The display panel needs to be moved and transported by a transfer carrier during the display panel transfer and transportation process. In the actual testing process, the carrier logistics transfer device also needs to balance the incoming material speed and the time consumed by the test, striving for maximum work efficiency, minimum logistics cost and material cost.

[0004] Therefore, it is necessary to develop a new type of carrier logistics transfer device that can realize the reuse of carriers and the efficient implementation of testing work, and assist in completing the finished product testing of display panels with lower time and equipment costs. Summary of the Invention

[0005] In response to the shortcomings of the prior art, the purpose of the present invention is to provide a carrier logistics transfer device and transfer method, which makes comprehensive improvements in the layout design of the transportation device and the design of structural components, and combines with a matching transfer method to assist in completing the finished product inspection of display panels with lower time and equipment costs.

[0006] To achieve the above-mentioned purpose, the present invention provides a carrier logistics transfer device, which can transfer display panels to be inspected to the inspection station set on the operating table, and includes a guide rail module, an inspection station, a feeding mover, a carrier return mover, a loading and unloading module and a discharging module, wherein:

[0007] The feed mover is slidably connected to one side of the guide rail module and is used to transport the carrier carrying the display panel to be inspected.

[0008] The carrier return flow is connected to the other side of the guide rail module and is used to recycle empty carriers.

[0016] In the above invention concept, the clamping parts included in the jig discharge sub-module are specifically forks, which are similar in shape to the forks of a forklift and can fork up the carrier from the bottom, or the clamping plates arranged relatively are driven by the clamping cylinders. The clamping plates open and close under the drive of the clamping cylinders, and can achieve the clamping or loosening of the two sides of the carrier.

[0017] Furthermore, the discharging module further includes a splitting submodule for separating the inspected display panel from the carrier, wherein:

[0018] The split sub-module includes a status detection module, a drive mechanism, and a cover-opening ejector. The drive mechanism is fixedly connected to the cover-opening ejector.

[0022] The discharging mover includes a base and a support plate. The base is slidably connected to the second linear motor module. The support plate is set on the base. The support plate is used to carry the carrier and is smaller than the carrier so that the carrier can extend out of the support plate.

[0023] Furthermore, the loading and unloading module includes a rotating shaft and at least two transplanting mechanical arms, and the at least two transplanting mechanical arms are vertically arranged around the rotating shaft, wherein:

[0033] The discharging movable element moves to the splitting sub-module so that the splitting sub-module can split the inspected display panel and the carrier.

[0034] In general, the above technical solutions conceived by the present invention have the following technical advantages compared with the existing technology:

[0035] 1. The device of the present invention is provided with a guide rail module, an inspection station, a feeding mover, a carrier return mover, a loading and unloading module and a discharging module, all of which are arranged around the guide rail module. The feeding mover and the carrier return mover are respectively arranged on both sides of the guide rail module, the discharging module is arranged at one end of the guide rail module, and the loading and unloading module is arranged on the guide rail module. The feeding mover transports the carrier carrying the display panel to be inspected, the carrier return mover is used to recover the empty carrier, the discharging module is used to separate the inspected display panel from the carrier, and is also used to separate the separated The inspection display panel is transferred to the next workstation, and the empty carrier after separation is transferred to the carrier return rotor. The loading and unloading module is used to transfer the carrier transported by the feeding rotor to the inspection station, and simultaneously transfer the carrier that has completed the inspection at the inspection station to the discharging module. The positions of the feeding rotor, carrier return rotor, loading and unloading module and discharging module are reasonably designed, and the division of labor of each part is clear, each part performs its duties, cooperates with each other, and has complete functions, which can fundamentally realize the overall assembly line operation of feeding, inspection, and carrier recovery.

[0036] 2. In the present invention, multiple inspection stations are arranged along both sides of the guide rail module, the feeding mover and the carrier return mover are respectively arranged on both sides of the guide rail module and can move back and forth along the guide rail module, the discharging module is arranged at one end of the guide rail module, and the loading and unloading modules are arranged on the guide rail module and can move along the guide rail module. The arrangement of each functional module makes one end of the guide rail module the carrier feeding end, which is also the empty carrier recovery end, and the other end of the guide rail module is the product and fixture discharging end. Such an overall layout forms a compact setting of space and function, and the compact structural design can help to achieve efficient execution of inspection work.

[0037] 3. The discharging module specifically includes a jig discharging sub-module, a product discharging sub-module, a discharging mover and a splitting sub-module. The jig discharging sub-module is used to transfer the combination of the display panel that has completed the inspection and the carrier that carries the display panel to the discharging mover. The discharging mover transports it along the guide rail module to the splitting sub-module. The splitting sub-module disassembles the buckles on the carrier to release the display panel that has completed the inspection. The product discharging sub-module is used to transfer the released display panel to the next workstation to complete the discharging. The current workstation is an empty carrier. The jig discharging sub-module is then used to transfer the current empty carrier to the carrier return flow circuit for the carrier return flow circuit to recycle the carrier, thereby enabling the carrier to be reused, reducing the number of carriers and reducing equipment costs. The overall structure of the discharge module is set at the discharge end of the product and the fixture. The fixture discharge sub-module and the product discharge sub-module are arranged relatively to each other, on both sides of the guide rail module respectively. The discharge mover and the splitting sub-module are arranged adjacent to each other. The structural subdivision makes the realization of various functions better connected, the design is ingenious, and the working efficiency is high.

[0038] 4. In the method of the present invention, first, the loading and unloading module and the feeding mover carrying the display panel carrier to be inspected are moved to the test station. Then, the two transfer robotic arms of the loading and unloading module can work simultaneously. One transfer robotic arm can pick up the carrier loaded with the display panel to be inspected on the feeding mover, and the other transfer robotic arm can synchronously pick up the carrier loaded with the inspected display panel on the test station. Then, the loading and unloading module rotates, and the two transfer robotic arms can each rotate 90 degrees. One transfer robotic arm puts the carrier loaded with the display panel to be inspected into the test station, and the other transfer robotic arm puts the carrier loaded with the display panel to be inspected into the test station. A transfer robot arm synchronously hands over the carrier of the inspected display panel to the discharging module. Then, the discharging module accepts the carrier of the inspected display panel and splits it. After splitting, the empty carrier and the inspected display panel are discharged separately, and the empty carrier is transferred to the carrier return flow circuit, and the carrier return flow circuit carrying the empty carrier moves to the loading and recycling end. The above work process is highly efficient, the process connection is reasonable and compact, and it realizes the recovery of the carrier and the inspection of the actual panel at the same time, which can assist in completing the finished product inspection of the display panel with lower time and equipment costs.

[0063] Figure 1aThis is a three-dimensional diagram of the display panel finished product inspection system structure of the present invention, in which the carrier logistics transfer device is a part, which can transfer the display panel to be inspected to the inspection station 400 set on the operating table 100. The display panel to be inspected is carried by the carrier. In order to observe clearly, Figure 1a The loading and unloading modules and the carrier return flow circuit are not shown, and due to the large number of components, some modules or structures are not marked with reference numerals. Figure 1b This is a top view of the structure diagram of the display panel finished product detection system in the present invention, which is a color rendering top view, showing the loading and unloading module and the carrier return flow circuit. The specific structure of the loading and unloading module can be found in Figure 4 Combining the two figures, we can see that the display panel finished product inspection system includes an operating table 100. The operating table 100 has a smooth surface and a frame-shaped bottom to support the operating table. The carrier logistics transfer device is set on the operating table 100, and the inspection station 400 is also set on the operating table 100. The inspection station 400 has an even number of stations, which are symmetrically arranged on both sides of the guide rail module 200 and are close to the guide rail module 200. Figure 1a and Figure 1b In the embodiment shown in , the number of detection stations 400 is 8, which are symmetrically arranged on both sides of the operating table, with 4 detection stations 400 on one side. In fact, the number of detection stations is not limited to 8, but can be 2 to 20 according to the actual engineering needs, and can be flexibly set. The detection station 400 has a circuit structure that can be used to light up the display panel to be detected. A specific structure thereof can refer to the patent application with application number 202310841220.6. The focus of the present invention application is on the carrier logistics transfer device, and the detection station 400 is not described in detail here.

[0064] Figure 2 This is a schematic diagram of the main structure of the carrier logistics transfer device in an embodiment of the present invention. Figure 3 This is a schematic diagram of the main structure of the carrier logistics transfer device product and the fixture discharge end in an embodiment of the present invention. Figure 3 yes Figure 2 The enlarged view of the partial cutout at the discharge end is used to more clearly show the main structure of the discharge end. Figure 2 and Figure 3 The loading and unloading modules are not shown. Figure 1a 、 Figure 1b 、 Figure 2 and Figure 3It can be seen that in one embodiment, the carrier logistics transfer device of the present invention includes a guide rail module 200, an inspection station 400, a feeding mover 500, a carrier return mover 600, a loading and unloading module 300 and a discharging module, wherein the feeding mover 500 is slidably connected to one side of the guide rail module 200 for conveying the carrier carrying the display panel to be inspected, and the carrier return mover 600 is slidably connected to the other side of the guide rail module 200 for recovering the empty carrier (after the display panel to be inspected is inspected, it is transferred to the next station, the current carrier is an empty carrier). The discharge module is set at one end of the guide rail module 200, and is used to separate the inspected display panel and the carrier, and is also used to transfer the separated inspected display panel to the next station, and transfer the empty carrier after separation to the carrier return flow element 600. The loading and unloading module 300 is set along the guide rail module 200, and is used to transfer the carrier transported by the feeding mover to the inspection station 400, and simultaneously transfer the carrier that has completed inspection at the inspection station 400 to the discharge module. The guide rail module 200 is set on the operating table 100, and preferably, it can be set near the center line of the operating table 100. The inspection stations 400 are arranged symmetrically on both sides of the guide rail module 200. The inspection station 400, the feeding mover 500, the carrier return mover 600, the loading and unloading module 300 and the discharging module are all arranged around the guide rail module 200. One end of the guide rail module 200 is the carrier feeding end, which is also the empty carrier recovery end. The other end of the guide rail module is the discharging end of the product and the fixture.

[0065] In one embodiment, the guide rail module 200 includes a second linear motor module 201 and a first linear motor module 202, Figure 1a 、 Figure 1b 、 Figure 2 and Figure 3It can be seen that the second linear motor module 201 and the first linear motor module 202 are arranged adjacent to each other and side by side. The feed mover 500, the discharge mover 1000 and the loading and unloading module 300 are all arranged on the first linear motor module, and the carrier return mover 600 is arranged on the second linear motor module. The first and second linear motor modules are purchased from the market and are mature products. The linear motor mainly consists of a stator, a mover, a sensor, a support structure and other auxiliary components such as a cooling system and a controller. The stator is the fixed part of the linear motor and is usually composed of an iron core and a winding. The iron core is mostly made of silicon steel sheets, and the winding is wound with wire and fixed on the iron core. The stator contains at least two electromagnets, which can be arranged according to different working methods. The main function of the stator is to generate a magnetic field and a basic, unchanging electromagnetic force. The mover or moving part is the output part of the linear motor, which is responsible for converting electrical energy into linear motion. The mover is generally composed of an iron core and a winding, and can be moved linearly through a guide rail or a guide frame. The mover is typically fixed to the load and moves at different positions and speeds based on information from the stator and sensors. Sensors monitor the motor's position, speed, and load, providing information about the motor to the controller. Based on sensor feedback, the controller adjusts the motor's current, position, and speed, achieving real-time control of the motor. Sensor types include photoelectric sensors, Hall sensors, and magnetic field sensors. The support structure, used to support and secure the linear motor and other modules, is typically composed of high-precision mechanical components such as guide rails, sliders, and bearings to ensure high-precision linear motion. Figure 1a 、 Figure 1b 、 Figure 2 and Figure 3 In the figure, the stator part of the linear motor is set under its supporting structure and cannot be observed for the time being. The mover is set on the guide rail of the supporting structure and can realize reciprocating movement.

[0066] Figure 4 This is a schematic diagram of the loading and unloading module structure in an embodiment of the present invention, which is a three-dimensional solid diagram rendered in color. Figure 5 yes Figure 4 The structural diagram of a single transplanting robot arm in the loading and unloading module is a color-rendered 3D solid diagram. Figure 4 and Figure 5It can be seen that in one embodiment of the present invention, the loading and unloading module 300 includes a rotating shaft 320, a first transplanting robot arm 310, and a second transplanting robot arm 330. The first transplanting robot arm 310 and the second transplanting robot arm 330 are connected to the rotating shaft 320 through an adapter plate. The rotating shaft 320 is connected to a rotating driving member, such as a rotating cylinder or a rotating motor. The driving member drives the first transplanting robot arm 310 and the second transplanting robot arm 330 to rotate through some structures such as adapter plates or directly connected to the rotating shaft. The first transplanting robot arm 310 and the second transplanting robot arm 330 have the same or similar structures. The first transplanting robot arm 310 and the second transplanting robot arm 330 are arranged on the same transition connecting plate. The center of the transition connecting plate is connected to the rotating shaft 320, and four connection stations are arranged in four directions along the circumference. The four connection stations are distributed at 90° intervals in the circumference. Therefore, in this embodiment, the first transplanting robot arm 310 and the second transplanting robot arm 330 are located on the same circumference and are 90° apart on the circumference.

[0067] Depend on Figure 5 It can be seen that the first transplanting robot arm 310 includes a rotating arm Z-axis 314, a clamping cylinder 311 and a clamping plate 312, which are the core components of the first transplanting robot arm and the second transplanting robot arm. It also includes some adaptive connection structures or support structures made to meet the needs of the project, and also includes an ion rod 313. Among them, the rotating arm Z-axis 314 is connected to the rotating shaft 320 through an adapter plate, the clamping cylinder 311 is connected to the rotating arm Z-axis 314, and the clamping plate 312 is connected to both sides of the clamping cylinder 311, and can be opened and closed under the drive of the clamping cylinder 311. The specific structure of the clamping plate can be designed to adapt to the needs of the project. It can be a whole piece or multiple pieces connected together. The clamping plate has a clamping end that directly contacts the side wall of the carrier. The clamping end is, for example, annular. Its specific structure is not the focus of discussion in the present invention application. Both the clamping principle and the clamping structure can be achieved by the existing technology. The claw cylinder 311 can drive the claw plate 312 to open or close relatively. When it is necessary to clamp a carrier, the claw cylinder drives the claw plate to open and move to the carrier. The carrier to be clamped is located in the middle of the relatively arranged claw plates 312. After alignment, the claw cylinder 311 drives the claw plates 312 to move relatively and close to clamp the carrier. The ion rod 313 is arranged above the claw plate 312 and aligned with the carrier station. It can be used to eliminate static electricity, remove dust and descaling for the display panel to be inspected. The rotating arm Z axis 314 is a Z axis module purchased from the market. It is used to drive the claw cylinder 311 and the claw plate 312 to move as a whole on the Z axis after being driven to adapt to the height of the carrier to be clamped. The first transplanting robot arm 310 also has some connecting plates, which are not listed one by one here. They are mainly provided for the convenience of transfer or connection.

[0068] Figure 6This is a schematic diagram of the feed mover structure in an embodiment of the present invention, which is a three-dimensional solid diagram rendered in color. Figure 9 This is a schematic diagram of the carrier return rotor structure in an embodiment of the present invention. It is a color-rendered three-dimensional solid diagram. As can be seen from the figure, in one embodiment of the present invention, the feed mover 500 includes a vertical connecting plate 501, a feed rotary cylinder 502, and a feed carrier station disc 503. The vertical connecting plate 501 is slidably connected to the first linear motor module 202. A horizontal plate is provided on the top surface of the vertical connecting plate 501. The feed rotary cylinder 502 is provided on the horizontal plate. A feed carrier station disc 503 for accommodating the carrier is provided on the top of the feed rotary cylinder 502. In actual engineering practice, the feed carrier station disc 503 can also be a circular chassis provided on the horizontal plate, with the carrier station provided on the chassis. The carrier return motor 600 includes a return rotary cylinder 601 and a return carrier station disk 602. The carrier return motor 600 has a similar structure to the feed motor 500. A circular return carrier station disk 602 can also be provided, and the carrier station is set on it. Rotary cylinders are provided on both the feed power and carrier return motors, mainly to adjust the direction of the carrier. When the carrier is feeding and unloading, the length direction of the carrier is parallel to the guide rail module 200. However, when the carrier is transported to the inspection station through the loading and unloading module and transferred from the inspection station to the splitting sub-module, the length direction of the carrier needs to be perpendicular to the guide rail module 200.

[0069] Figure 7 It is a structural diagram of the combination of the splitting sub-module and the discharge mover 1000 in an embodiment of the present invention. It is a color-rendered three-dimensional solid diagram. The discharge mover 1000 is set on the second linear module and works between the loading and unloading module and the splitting sub-module. It is used to transfer the display panel carrier that has completed the inspection handed over by the loading and unloading module to the splitting sub-module. As can be seen from the figure, in one embodiment of the present invention, the disassembly sub-module 900 mainly includes a cover-opening ejector 902, a status detection module 901 and a driving mechanism 903. The cover-opening ejector is arranged at the bottom of the disassembly sub-module 900, and the driving mechanism 903 is fixed to the cover-opening ejector 902. The driving mechanism 903 is, for example, a Z-axis cylinder, a hydraulic cylinder or a screw mechanism, which is used to drive the cover-opening ejector 902. The cover-opening ejector 902 is arranged below the discharge mover 1000 and is used to release the restraint of the carrier on the display panel by the buckle of the inspected carrier on the top cover discharge mover 1000 after being driven by the driving mechanism 903. The status detection module 901 is arranged near the cover-opening ejector 902 and is located at the bottom of the carrier station. It can be used to sense whether the carrier is pushed open. When the carrier is pushed open, the buckle on the carrier is opened, and the product discharge sub-module 800 can absorb and transfer or pull the side wall of the display panel to transfer the display panel that has been inspected.

[0070] from Figure 7It can also be learned that the discharge mover 1000 includes a base 1002 and a support plate 1001. The base 1002 is slidably connected to the second linear motor module. The support plate 1001 is set on the base 1002. The support plate 1001 is used to carry the carrier, and its volume is smaller than the carrier, so that the carrier can extend out of the support plate. The part of the carrier extending out of the plate is located above the cover opening pin, and the cover opening pin is inserted into to push open the buckle.

[0071] Figure 7 The key structural parts of the split sub-module 900 and the discharge mover 1000 are given, and other parts are not shown. The parts not shown are mainly connecting or supporting components, which are designed according to specific spatial positions, weight requirements, etc.

[0072] Figure 8 It is a schematic diagram of the structure of the jig discharge sub-module in an embodiment of the present invention, which is a color-rendered three-dimensional solid diagram. In one embodiment of the present invention, the jig discharge sub-module 700 includes a Y-axis module 701, a Z-axis module 702 and a clamping member 703. The Z-axis module 702 is connected to the Y-axis module 701, and the clamping member 703 is arranged on the Z-axis module. The clamping member 703 is a clamping plate driven by a fork arm or a clamping cylinder. The clamping member also serves as a transfer carrier. Its structure can be designed with reference to the corresponding part of the first transplanting robot arm 310. Figure 8 The fixture discharge sub-module 700 is installed on the operating table through two columns. The Y-axis module and the Z-axis module are purchased from the market. Figure 8 Some installation boards for control circuits are also displayed. This is part of the actual engineering structure because the entire display panel finished product inspection system involves some control circuits that need to be adaptively stored and installed. This is not the key point discussed in this application, but a mature product on the market.

[0073] In one embodiment of the present invention, the product discharging sub-module 800 and the jig discharging sub-module 700 are arranged on both sides of the guide rail module 200, and the two are arranged along the Y direction. The product discharging sub-module 800 is used to adsorb and transfer the inspected display panel, and the jig discharging sub-module 700 is used to clamp and transfer the empty carrier. The product discharging sub-module 800 is also set on the operating table 100 through two columns, including a Y-direction module, a Z-direction module and a discharging clamp. Its specific structure can refer to the jig discharging sub-module, except that the discharging clamp is used to transfer the display panel instead of the carrier. It can be a handle to pull the side wall of the display panel or a suction cup to adsorb, such as a suction cup or a fork structure.

[0074] The method for transporting logistics using the above device includes the following key steps:

[0075] S1: The loading and unloading module 300 and the loading element carrying the display panel to be inspected move to the station to be inspected;

[0077] S3: The loading and unloading module 300 places the carrier loaded with the display panel to be inspected into the test station and simultaneously hands over the carrier of the inspected display panel to the discharge module. More specifically, the loading and unloading module 300 places the carrier loaded with the display panel to be inspected into the test station and simultaneously places the carrier of the inspected display panel onto the discharge mover 1000. The discharge mover 1000 moves to the separation sub-module 900 so that the separation sub-module 900 can separate the inspected display panel and the carrier.

[0078] S4: The discharging module discharges the inspected display panels and transfers the separated empty carrier to the carrier return flow circuit 600;

[0079] S5: The carrier return flow circuit 600 carrying the empty carrier moves to the loading and recovery end.

[0080] In actual engineering, a more specific and detailed step is as follows:

[0081] S1: The feeding mover receives the carrier carrying the display panel to be inspected and slides to the vicinity of the loading and unloading module 300.

[0082] S2: Adjust and confirm the working positions of the first rotating arm sub-module 310 and the second rotating arm sub-module 330 on the loading and unloading module 300, so that the first rotating arm sub-module 310 and the second rotating arm sub-module 330 are aligned with the loading and unloading module 300 and the inspection station 400 respectively.

[0083] There is no particular order for steps S1 and S2, and they can also be performed simultaneously.

[0084] S3: The first rotating arm sub-module 310 and the second rotating arm sub-module 330 work simultaneously, picking up the carrier to be inspected on the upper and lower material molds 300 and picking up the inspected carrier on the inspection station 400.

[0085] S4: The discharging mover 1000 slides to the vicinity of the loading and unloading module 300.

[0086] There is no particular order for steps S3 and S4, and they can also be performed simultaneously.

[0087] S5: After the picking is completed, the loading and unloading module 300 rotates the angle so that the first rotating arm sub-module 310 and the second rotating arm sub-module 330 are aligned with the inspection station 400 and the discharge mover 1000 respectively. The first rotating arm sub-module 310 and the second rotating arm sub-module 330 work simultaneously to place the carrier to be inspected on the inspection station 400 and the inspected carrier on the discharge mover 1000 at the same time.

[0088] S6: The discharging mover 1000 moves to the vicinity of the splitting sub-module 900, the inspected carrier is split, the discharging sub-module 800 completes the discharging of the inspected display panel, and the fixture discharging sub-module 700 completes the discharging of the empty carrier.

[0089] S7: The carrier return flow circuit 600 receives the empty carrier and moves it to the recovery end.

[0090] Repeat the above steps, work continuously, and continuously perform display panel inspection and empty carrier recovery.

[0091] It will be easily understood by those skilled in the art that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
