Description

Technical Field

[0001] The present invention relates to the field of precision manufacturing technology, and in particular to a device and method for pre-identifying the intrinsic pressure of a silicon-based OLED product. Background Art

[0002] Silicon-based OLED replaces the glass substrate of traditional OLED with a single-crystal silicon substrate. Bonding pre-pressing identification of silicon-based OLED products is an alignment and identification technology for silicon-based OLED (organic light-emitting diode) products in the Bonding process. It aims to achieve precise alignment of products through a high-precision identification system, thereby improving production efficiency and product quality.

[0003] Silicon-based OLED products are usually composed of single-crystal silicon substrates and other materials (such as FPC flexible circuit boards), which have certain rigidity and brittleness. Since the single-crystal silicon substrate has strong rigidity and low ductility, and the FPC flexible circuit board is relatively soft and has certain bendability, the uniformity of force distribution is very important when clamping it. If the clamping force is uneven, it will directly affect the physical state and form of the product, resulting in inaccurate positioning.

[0004] Specifically, due to its high rigidity, the monocrystalline silicon substrate is not easily deformed when clamped, while the FPC flexible circuit board is relatively soft and more susceptible to uneven clamping force. If the clamping force is unevenly distributed between the two, the flexible circuit board will sink or deviate from its original position due to excessive local pressure. This mechanical imbalance will cause positional errors, affecting the accuracy and quality of the entire silicon-based OLED product. Summary of the invention

[0022] (III) Beneficial effects

[0023] Compared with the prior art, the present invention provides a device and method for pre-identifying the actual pressure of a silicon-based OLED product, which has the following beneficial effects:

[0024] 1. The pressure pre-identification device and method of the silicon-based OLED product are arranged by a pressing mechanism. The output end of the telescopic motor drives the detection head to move downward, so that the bottom disc block contacts the workpiece. At this time, the telescopic sealing tube is compressed, so that the air in the telescopic sealing tube is squeezed, and the pressure is evenly transmitted to various parts of the workpiece through the hollow inner wall of the cube block; because the telescopic sealing tubes are interconnected through the inner wall of the cube block, the pressing force can be evenly distributed on the surface of the workpiece, ensuring that various parts of the workpiece are evenly pressed, thereby avoiding positioning errors or workpiece deformation caused by uneven distribution of force.

[0025] 2. The pressure pre-identification device and method for silicon-based OLED products utilizes a side positioning mechanism to ensure uniform pressure on all sides of the workpiece. Since the pressing force is evenly distributed, the workpiece will be subjected to balanced pressure on all sides to avoid local excessive pressure or deformation. This design is particularly suitable for process steps that require precise positioning and stable fixation, such as the Bonding process of silicon-based OLED products, and further enhances the alignment accuracy.

[0026] 3. The pressure pre-identification device and method of the silicon-based OLED product utilizes a side positioning mechanism to blow the workpiece before pressing and positioning to prevent dust and impurities from affecting the positioning accuracy. If there is dust or impurities on the surface or around the workpiece, these tiny particles may affect the contact between the workpiece and the receiving seat, making the contact uneven during the pressing and positioning process and causing errors.

The pressurizing mechanism can accurately control the size of the pressing force to ensure that the pressing requirements of different workpieces are met, avoiding inaccurate alignment or damage to the workpiece due to excessive or insufficient pressure.

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] See also Figure 1-Figure 8, a silicon-based OLED product pre-pressure identification device, including a body 1, which is used to provide support and frame structure for the entire device, and it carries and fixes various key components in the device; a telescopic motor 2, which is used to provide downward reciprocating driving force, and the telescopic motor 2 is fixedly connected to the outer wall of the body 1; a receiving seat 3, which is used to place and support the silicon-based OLED workpiece to be processed, and the receiving seat 3 is arranged on the body 1 to ensure that the workpiece is in a stable position during the pre-pressure identification process. It provides a fixed platform for the workpiece, so that the workpiece can be accurately docked with a pressing mechanism 4, a positioning system, etc., to ensure that the workpiece does not move or displace during the entire operation process, thereby improving the alignment accuracy and work efficiency; the pressing mechanism 4 is used to provide a stable and uniform pressing force to the silicon-based OLED workpiece, and by controlling the strength and position of the pressing, appropriate pressure is applied to prevent uneven clamping or uneven pressure from causing The side positioning mechanism 5 is used to accurately position the plane position of the silicon-based OLED workpiece before pressing. It ensures that the workpiece maintains the correct angle and position during the pressing process through a precise mechanical structure or positioning element, thereby avoiding the alignment error caused by the displacement or misalignment of the workpiece. The side positioning mechanism 5 provides a stable reference for the subsequent pressing and identification process to ensure the accuracy and reliability of the entire operation; the pressing mechanism 6 is used to adjust the pressing force of the pressing mechanism 4 so that the applied pressure can be flexibly adjusted according to the requirements of different models of silicon-based OLED workpieces. The pressing mechanism 6 can accurately control the size of the pressing force to ensure that the pressing requirements of different workpieces are met, avoiding inaccurate alignment or damage to the workpiece due to excessive or insufficient pressure. This mechanism can automatically or manually adjust the pressure according to the characteristics of the workpiece, thereby improving the adaptability and work efficiency of the device.

[0039] The pressing mechanism 4 is arranged at the bottom of the telescopic motor 2. The pressing mechanism 4 includes a detection head 41. The detection head 41 is fixedly connected to the output end of the telescopic motor 2. The detection head 41 is infrared light. In the Bonding pre-pressing identification process of silicon-based OLED products, the main function of the detection head 41 using infrared light is to overcome the light transmittance problem of the single-crystal silicon substrate. Since the refractive index of the single-crystal silicon substrate in the visible light range is relatively high, it is impossible to directly identify the front feature points of the workpiece through visible light. Traditional visual recognition technologies such as CCD have the defect of being unable to penetrate the single-crystal silicon substrate during the identification process of silicon-based OLED workpieces. By using infrared light, the detection head 41 can effectively penetrate the single-crystal silicon substrate for transmission identification. Specifically, single-crystal silicon has a lower refractive index in the infrared spectrum range, so that infrared light can better penetrate the substrate, thereby realizing the identification of the internal or front feature points of the substrate. Infrared recognition technology relies on infrared sensors or camera equipment, which can capture The infrared signal emitted or reflected by the object is converted into an electrical signal, which is then analyzed by the image processing system to obtain accurate positioning information. Through infrared recognition, accurate positioning and alignment can be performed without affecting the structure of the workpiece, thereby improving the working efficiency and positioning accuracy of the equipment. This method of using infrared light for recognition can solve the light transmittance problem encountered by the traditional CCD vision system in silicon-based OLED workpiece detection, avoids the complexity of using two sets of vision systems to recognize different faces, and significantly improves the recognition accuracy and the degree of automation of the process. The bottom of the detection head 41 is fixedly connected to a cube block 42, and a through groove 43 is opened on the inner wall of the cube block 42. The through groove 43 is used to facilitate the leakage of the lens of the detection head 41, so that the lens of the detection head 41 can be smoothly leaked from the cube block 42, thereby realizing efficient detection and recognition of silicon-based OLED products, and a pressing piece 44 is provided at the bottom of the cube block 42.

[0040] The pressing member 44 includes a top disc block 441, which is fixedly connected to the bottom of the cube block 42, one end of a spring 442 is fixedly connected to the bottom of the top disc block 441, the other end of the spring 442 is fixedly connected to the bottom disc block 443, one end of a telescopic sealing tube 444 is fixedly connected to the top of the bottom disc block 443, the other end of the telescopic sealing tube 444 is fixedly connected to the bottom of the top disc block 441, a through hole is opened on the inner wall of the top disc block 441, and the inner wall of the cube block 42 is fixedly connected to the bottom of the top disc block 441. The wall is hollow, and the hollow inner wall of the cube block 42 is connected to the telescopic sealing tube 444 through the through hole on the inner wall of the top disc block 441, so that when the bottom disc block 443 presses the workpiece, the bottom disc block 443 squeezes the spring 1 442 and the telescopic sealing tube 444, so that the telescopic sealing tube 444 is compressed. At the same time, because the telescopic sealing tubes 444 are mutually connected through the hollow inner wall of the cube block 42, and because the telescopic sealing tubes 444 are mutually connected through the hollow inner wall of the cube block 42, the transmission of the pressing force is more uniform. Such a design ensures that during the pressing process, the force can be evenly distributed to various parts of the workpiece, thereby improving the control accuracy of the workpiece and avoiding the alignment error or workpiece deformation caused by uneven force distribution. The compression of the telescopic sealing tube 444 and its communication channel with the cube block 42 provide a flexible pressure adjustment function, so that during the pressing process, the size of the pressing force can be accurately controlled by adjusting the degree of compression to adapt to workpieces of different sizes or rigidities.

[0041] The side positioning mechanism 5 includes a fixed cuboid 51, which is fixedly connected to the top of the receiving seat 3. A vertical cylinder 52 is slidably connected to the inner wall of the fixed cuboid 51, a piston square block 53 is fixedly connected to the bottom of the vertical cylinder 52, the top of the vertical cylinder 52 is fixedly connected to the output end of the telescopic motor 2, a connecting pipe 54 is fixedly connected to the outer wall of the fixed cuboid 51, a locking mechanism 55 is fixedly connected to the outer wall of the connecting pipe 54, the inner wall of the connecting pipe 54 is connected to the inner wall of the fixed cuboid 51, and the outer wall of the piston square block 53 is piston-connected to the inner wall of the fixed cuboid 51.

[0042] The locking mechanism 55 includes a lightweight fixing part 551, which is fixedly connected to the outer wall of the connecting pipe 54. One end of a spring 552 is fixedly connected to the inner wall of the lightweight fixing part 551, and the other end of the spring 552 is fixedly connected to a reciprocating piston 553. A through hole 554 is provided on the inner wall of the reciprocating piston 553. The outer wall of the through hole 554 is connected to the inner wall piston of the lightweight fixing part 551. A pressing block 555 is fixedly connected to the outer wall of the through hole 554. An air injection hole 556 is provided on the inner wall of the pressing block 555. Four groups of locking mechanisms 55 are provided. The four groups of locking mechanisms 55 are arranged in a circular array and are used to simultaneously press and position the four sides of the workpiece to ensure uniform pressing on the four sides of the workpiece. Since the pressing force is evenly distributed, the four sides of the workpiece will be subjected to balanced pressure to avoid local excessive pressing or deformation. Such a design is particularly suitable for process processes that require precise positioning and stable fixing, such as the Bonding process of silicon-based OLED products, and further enhances the positioning accuracy.

[0043] The pressurizing mechanism 6 includes a telescopic tube 61, one end of which is fixedly connected to the top of the fixed rectangular parallelepiped 51 through the telescopic tube 61, and a receiving plate 62 is fixedly connected to the other end of the telescopic tube 61, and one end of a telescopic rod 63 is fixedly connected to the bottom of the receiving plate 62, and the other end of the telescopic rod 63 is fixedly connected to the top of the fixed rectangular parallelepiped 51, and the inner wall of the fixed rectangular parallelepiped 51 is connected to the inner wall of the telescopic tube 61, and a weight 64 is arranged on the top of the receiving plate 62. The gravity of the weight 64 will squeeze the telescopic tube 61 downward, further increase the pressure in the fixed rectangular parallelepiped 51, and then increase the pressure inside the fixed rectangular parallelepiped 51. This design increases the pressure applied to the workpiece through the direct action of the weight 64, ensuring that sufficient force can be provided in the pre-pressing stage to ensure the precise positioning and stable fixation of the workpiece. The weight 64 provides continuous pressure through its own weight, which means that even if the input of the external power source changes, the weight 64 can still maintain a certain pressure, thereby increasing the stability and reliability of the system. This design does not require an external dynamic force source to continuously apply pressure, but instead uses gravity to adaptively adjust the pressure, simplifying the power system of the device.

[0044] A method for using a silicon-based OLED product pressure pre-identification device, further comprising the following method of use:

[0045] Step 1: Place the silicon-based OLED workpiece at the center of the receiving seat 3, then turn on the output end of the telescopic motor 2 to move downward, the output end of the telescopic motor 2 drives the vertical cylinder 52 to move downward, the vertical cylinder 52 drives the piston block 53 to move downward, the piston block 53 squeezes the air in the fixed rectangular parallelepiped 51, so that the air in the fixed rectangular parallelepiped 51 enters the lightweight fixing part 551 through the connecting pipe 54, the high-pressure air in the lightweight fixing part 551 squeezes the reciprocating piston part 553 and the pressing block 555 to squeeze and position the workpiece around, in this way, the pressing block 555 applies uniform pressure around the workpiece, avoiding some areas from being subjected to excessive pressure and other areas from being subjected to too little pressure, thereby reducing the alignment error caused by uneven pressure;

[0046] Step 2: At the same time, the air squeezed by the reciprocating piston 553 enters the inner wall of the reciprocating piston 553 and the pressing block 555 through the hole 554, and then is ejected through the air jet hole 556 to blow the workpiece before pressing and positioning to prevent dust and impurities from affecting the positioning accuracy. If there is dust or impurities on the surface or around the workpiece, these tiny particles may affect the contact between the workpiece and the receiving seat 3, making the contact uneven during the pressing and positioning process, resulting in errors. The airflow ejected from the air jet hole 556 blows the workpiece, which can prevent these pollutants from causing the workpiece to deviate from the accurate position, thereby ensuring the accuracy of positioning;

[0047] Step three: When positioning is completed, the output end of the telescopic motor 2 drives the detection head 41 to move downward, the detection head 41 drives the cube block 42 to move downward, and the cube block 42 drives the pressing piece 44 to move downward, so that the bottom disc block 443 contacts the workpiece, and the telescopic sealing tube 444 is compressed at this time, so that the air in the telescopic sealing tube 444 is squeezed, and the pressure is evenly transmitted to various parts of the workpiece through the hollow inner wall of the cube block 42; because the telescopic sealing tubes 444 are interconnected through the inner wall of the cube block 42, the pressing force can be evenly distributed on the surface of the workpiece, ensuring that various parts of the workpiece are evenly pressurized, thereby avoiding positioning errors or workpiece deformation caused by uneven distribution of force.
