Description

Technical Field

[0001] This utility model relates to the field of packaging technology, and in particular to a packaging device. Background Technology

[0002] The pixels in a display panel are composed of electronic components such as liquid crystal molecules, semiconductors, batteries, and circuits. The control chip of the display panel processes the input digital signals and converts them into the required pixel brightness values, thereby forming images or text displayed on the screen. During the manufacturing process of a display panel, the metal substrate, including traces and electrodes, needs to be cut, resulting in some metal being exposed on the sides of the display panel. Exposed metal is prone to oxidation and corrosion, causing a decrease in the reliability of the display panel. Therefore, the sides of the display panel need to be encapsulated.

[0003] Currently, side packaging of display panels mostly uses pad printing, a high-precision printing process commonly used in the production of complex shapes or items with high surface requirements, such as electronic components, optical instruments, medical devices, ceramics, and glass. Pad printing can clearly and accurately reproduce details such as patterns, text, and markings. Because of its strong adaptability and compatibility with different substrates, pad printing is widely used in manufacturing. However, pad printing has drawbacks such as complex process flow and low efficiency.

[0004] A Chinese patent document, CN114883472A, discloses a "Side Encapsulation Method for a Display Panel and a Display Panel." This patent uses a side encapsulation mold to cover the exposed metal on the first side of the display panel with side encapsulation adhesive, preventing corrosion of the exposed metal and thus avoiding oxidation and corrosion, thereby improving the reliability of the display panel. However, this patent relies on a specially designed side encapsulation mold and is not suitable for side encapsulation of display panels of different shapes and sizes. Utility Model Content

[0005] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a packaging device to solve the problems of complex process and low efficiency in the existing side packaging of display panels using pad printing process.

[0006] To achieve the above and other related objectives, this utility model provides a packaging device, including a loading and unloading mechanism, a transport mechanism, a flipping mechanism, and at least two packaging printing mechanisms. The packaging printing mechanism is used to sequentially print packaging material on the side of a substrate. The flipping mechanism is driven to the substrate and is used to drive the substrate to flip. The transport mechanism is used to transport the substrate to the processing station of the packaging printing mechanism.

[0007] In the above technical solution of this application, a packaging device is formed by adopting a loading and unloading mechanism, a conveying mechanism, a flipping mechanism and at least two packaging printing mechanisms. The packaging device can provide two or more packaging printing stations for packaging at the same time. The loading and unloading mechanism and the conveying mechanism can realize the automation of substrate position change during the packaging process. The flipping mechanism can flexibly change the packaging position of the substrate. Compared with the pad printing process used in the prior art, the packaging process of this application is simpler and more efficient.

[0008] Preferably, the encapsulation printing mechanism includes an XY motion platform and a printing mechanism disposed above the motion platform. The printing mechanism includes a dispensing machine and a printing needle assembly. The motion platform is provided with a rotating mechanism and a horizontal suction cup and a vertical suction cup for carrying the substrate. The rotating mechanism includes a horizontal rotating mechanism for driving the horizontal suction cup to rotate in the horizontal direction and a vertical rotating mechanism for driving the vertical suction cup to rotate in the vertical direction.

[0009] In the above technical solution of this application, the use of horizontal and vertical suction cups to support the substrate can provide a stable fixation for the upper, lower and side encapsulation printing of the substrate. The use of a horizontal rotation mechanism to drive the horizontal suction cup to rotate in the horizontal direction and a vertical rotation mechanism to drive the vertical suction cup to rotate in the vertical direction can flexibly adjust the position of the suction cups according to the requirements of the encapsulation printing position, thereby improving the automation of encapsulation printing and increasing efficiency.

[0010] Preferably, the encapsulation printing mechanism further includes a ranging component, a calibration component, and a needle cleaning component. The calibration component includes a vertical positioning component and a horizontal positioning component. The calibration component is used to calibrate the position of the substrate before printing and provide feedback to the rotation mechanism. The rotation mechanism is used to drive the horizontal suction cup and / or the vertical suction cup to rotate to the corresponding printing position according to the feedback result. The ranging component is used to test the thickness of the encapsulation film formed after printing. The printing needle assembly includes a plurality of printing needles, and the needle cleaning component is used to clean the printing needles.

[0011] A calibration component is used to calibrate the position of the substrate before printing and feed the feedback to the rotation mechanism. The rotation mechanism drives the horizontal and / or vertical suction cups to rotate to the corresponding printing position based on the feedback result. A ranging component is used to test the thickness of the encapsulation film formed after printing, which can synergistically improve the accuracy of encapsulation printing.

[0012] More preferably, both the vertical positioning component and the horizontal positioning component are CCD vision positioning components.

[0013] Preferably, the flipping mechanism includes a linear module, a flipping gripper mounted above the linear module, and a flipping drive for driving the flipping gripper to flip. A transition suction cup is provided between the linear module and the flipping gripper. The transition suction cup can move linearly along the linear module. A lifting mechanism is provided between the transition suction cup and the linear module. The lifting mechanism includes a lifting drive and a lifting plate. The lifting drive is used to drive the lifting plate to move the transition suction cup closer to or away from the flipping gripper.

[0014] In the above technical solution of this application, the flipping principle is as follows: A transition suction cup carries the substrate to be flipped and, in conjunction with a linear module, transports it to the corresponding position of the lifting plate directly below the flipping gripper. A lifting drive component drives the lifting plate to move the transition suction cup closer to the flipping gripper. The flipping gripper then grasps the substrate. The lifting drive component drives the lifting plate to move the transition suction cup away from the flipping gripper to ensure sufficient flipping space. The flipping drive component then drives the flipping gripper to complete the flipping. The lifting drive component drives the lifting plate to move the transition suction cup closer to the flipping gripper again. The flipping gripper releases the flipped substrate, and the transition suction cup picks up the substrate and transports it along the linear module to the next processing station. Both the transition suction cup and the flipping gripper are based on the principle of negative pressure adsorption for adsorption and grasping.

[0015] Preferably, the handling mechanism includes at least two six-axis robots, each six-axis robot comprising a robot body and a variable-pitch gripper.

[0016] In the above-described technical solution of this application, the six-axis robot has six rotation axes, including a base drive axis, a shoulder drive axis, an arm drive axis, a wrist flipping axis, and a gripper drive axis. Each axis can rotate directly and independently, giving the handling mechanism of this application high operability in the processing space. The variable-pitch gripper can adjust the spacing of the gripping parts as needed to adapt to substrates of different sizes, enabling the gripper to flexibly meet the needs of different workstations and improve the efficiency of packaging and printing.

[0017] Preferably, the loading and unloading mechanism includes a loading unit, an unloading unit, and a positioning component for photographing and positioning the loading and unloading substrates. The loading unit includes a loading conveyor linear module, a loading suction cup for carrying the substrate, a loading barcode scanning unit, and a loading variable-pitch linear module. The loading suction cup is movably disposed above the loading conveyor linear module and can move linearly along the loading conveyor linear module. The unloading unit includes an unloading conveyor linear module, an unloading suction cup for carrying the substrate, an unloading barcode scanning unit, and an unloading variable-pitch linear module. The unloading suction cup is movably disposed below the unloading conveyor linear module and can move linearly along the unloading conveyor linear module.

[0018] Preferably, the loading unit and / or unloading unit further includes a cleaning unit for cleaning the substrate carried by the loading unit and / or unloading unit.

[0019] More preferably, the cleaning unit employs a dry ultrasonic dust removal device (USC).

[0020] Preferably, the positioning components include a loading positioning component and a unloading positioning component. Using the loading and unloading positioning components allows for the positioning of the substrate during the loading and unloading stages, ensuring the stability of the entire production line.

[0021] More preferably, both the loading and unloading positioning components adopt CCD vision positioning components.

[0022] Preferably, along the production line direction, the packaging device further includes a buffer platform, a curing oven, and a cooling platform in sequence before the unloading unit. The curing oven is used to cure the packaging material on the surface of the substrate after packaging. The buffer platform includes several parallel buffer units for temporarily storing the substrate to be cured that needs to be transported to the curing oven. The cooling platform includes several parallel cooling units for cooling the cured substrate that needs to be transported to the unloading unit.

[0023] Preferably, a transfer station is provided before the buffer station, the transfer station being used to carry the substrate that needs to be transported to the buffer station.

[0024] As described above, the packaging device of this utility model has the following beneficial effects:

[0025] (1) The packaging device of this application can provide two or more packaging printing stations for packaging at the same time. The loading and unloading mechanism and the conveying mechanism can realize the automation of substrate position change during the packaging process. The flipping mechanism can flexibly change the packaging position of the substrate. Compared with the pad printing process used in the prior art, the packaging process using the device of this application is simpler and more efficient.

[0026] (2) The use of horizontal and vertical suction cups to support the substrate can provide a stable fixation for the upper, lower and side packaging printing of the substrate. The use of a horizontal rotation mechanism to drive the horizontal suction cup to rotate in the horizontal direction and a vertical rotation mechanism to drive the vertical suction cup to rotate in the vertical direction can flexibly adjust the position of the suction cup according to the requirements of the packaging printing position, improve the automation of packaging printing and increase efficiency.

[0027] (3) The handling mechanism adopts a six-axis robot with six rotating axes equipped with a variable-pitch gripper. Each axis can rotate directly and independently, which makes the handling mechanism highly operable in the processing space. The variable-pitch gripper can adjust the spacing of the gripping parts as needed to adapt to substrates of different sizes, so that the gripper can flexibly meet the needs of different workstations and improve the efficiency of packaging and printing.

[0044] In the embodiments of this application above, the vertical positioning component, horizontal positioning component, loading positioning component, and unloading positioning component all adopt CCD vision positioning components.

[0045] like Figure 1 As shown, in the packaging device of the embodiment, the six-axis robot near the loading unit is named No. 1 six-axis robot, the six-axis robot near the unloading unit is named No. 2 six-axis robot, the packaging printing mechanism near the loading unit is named No. 1 packaging printing mechanism, and the packaging printing mechanism far from the loading unit is named No. 1 packaging printing mechanism.

[0046] The working principle of the packaging device in this application embodiment is as follows:

[0047] S1: The feeding unit 4 uses the feeding suction cup 42 to receive the substrate from upstream, the feeding conveying linear module 41 to transport the substrate to the cleaning unit 45 for cleaning, the feeding scanning unit 43 to scan the substrate, and then the substrate is transported to the picking position of the No. 1 six-axis robot. The No. 1 six-axis robot picks up the substrate and places it at the feeding positioning component 46 for photographing and positioning; S2: The No. 1 six-axis robot picks up the substrate and places it horizontally on the horizontal suction cup 33 of the No. 1 packaging printing mechanism 3. The horizontal positioning component 36 marks the position of the substrate and feeds back to the horizontal rotation mechanism. The horizontal rotation mechanism drives the horizontal suction cup to rotate to the corresponding printing position according to the feedback result. Then the printing mechanism prints the packaging material on the front of the substrate, and the ranging component detects the thickness of the packaging film formed after printing on the front of the substrate;

[0048] S3: The No. 1 six-axis robot picks up the substrate with the front-side encapsulation completed and flips it 90°, placing it on the vertical suction cup 34 of the No. 1 encapsulation printing mechanism 3. The vertical positioning component 35 is used to mark the position of the substrate and feeds back to the vertical rotation mechanism. The vertical rotation mechanism drives the vertical suction cup to rotate to the corresponding printing position according to the feedback result. Then, the printing mechanism prints the encapsulation material on the top side of the substrate. The ranging component is used to detect the thickness of the encapsulation film formed after printing on the top side of the substrate.

[0049] S4: The No. 1 six-axis robot picks up the substrate, flips it 180°, and then places it on the vertical suction cup 34 of the No. 1 packaging printing mechanism 3. The vertical positioning component 35 is used again to calibrate the position of the substrate and feeds back to the vertical rotation mechanism. The vertical rotation mechanism drives the vertical suction cup to rotate to the corresponding printing position according to the feedback result. Then, the printing mechanism prints the packaging material on the side and bottom of the substrate. The ranging component is used to detect the thickness of the packaging film formed after printing on the side and bottom of the substrate.

[0050] S5: The six-axis robot (No. 1) grips the substrate and places it onto the transition suction cup 24 of the flipping mechanism 2. The transition suction cup carries the substrate to be flipped and, in conjunction with the linear module 21, transports it to the corresponding position of the lifting plate 26 directly below the flipping gripper 22. The lifting drive component 25 drives the lifting plate 26 to move the transition suction cup 24 closer to the flipping gripper 22. The flipping gripper 22 grips the substrate. The lifting drive component 25 drives the lifting plate 260 to move the transition suction cup away from the flipping gripper to ensure sufficient flipping space. The flipping drive component 25 drives the flipping gripper 22 to complete the forward and reverse flipping of the substrate, so that the bottom surface of the substrate faces upward. The lifting drive component drives the lifting plate to move the transition suction cup closer to the flipping gripper again. The flipping gripper releases the flipped substrate, and the transition suction cup picks up the bottom-facing substrate and outputs it along the linear module 21.

[0051] S6: The No. 1 six-axis robot picks up the substrate and places it horizontally on the horizontal suction cup 33 of the No. 1 packaging and printing mechanism 3. The horizontal positioning component 36 is used to mark the position of the substrate and feeds back to the horizontal rotation mechanism. The horizontal rotation mechanism drives the horizontal suction cup to rotate to the corresponding printing position according to the feedback result. Then, the printing mechanism prints the packaging material on the bottom surface of the substrate. The ranging component is used to detect the thickness of the packaging film formed after printing on the bottom surface of the substrate, thus completing the side packaging of the substrate.

[0052] S7: The No. 1 six-axis robot picks up the substrate with the side encapsulation completed and puts it on the transfer station 9. The No. 2 six-axis robot picks up the substrate and puts it on the buffer station 6. The picking action is repeated to place the 7 substrates into the 7 buffer units respectively. The No. 2 six-axis robot picks up the 7 substrates from the buffer units and puts them into the curing oven 7 for curing.

[0053] S8: The No. 2 six-axis robot sequentially picks up the 7 cured substrates from the curing oven 7 and places them onto the 7 parallel cooling units 81 in the inner cooling platform 8 for cooling.

[0054] S9: The No. 2 six-axis robot sequentially picks up the 7 substrates after cooling from the cooling table 7 and places them at the unloading and positioning component for photo positioning. Then, it places them on the unloading and conveying linear module of the unloading unit 5. The unloading and conveying linear module is used to transport the packaged substrate to the cleaning unit for cleaning. The unloading and scanning unit scans the substrate and then transports it to the next processing station.

[0055] The working principle of the No. 2 packaging printing mechanism is exactly the same as that of the No. 1 packaging printing mechanism, and will not be described again here.

[0056] In summary, the packaging device of this invention can simultaneously provide two or more packaging printing stations for packaging. The use of loading / unloading mechanisms and conveying mechanisms automates the substrate position changes during the packaging process, while the flipping mechanism allows for flexible changes in the substrate's packaging position. Compared to the pad printing process used in existing technologies, the packaging process of this application is simpler and more efficient. Therefore, this invention effectively overcomes the various shortcomings of existing technologies and has high industrial applicability.

Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
