Description

Technical Field

[0001] The present invention relates to the technical field of exposure machines, and more particularly to a large glass frame automatic lifting and flipping device. Background Art

[0002] An exposure machine is a key device used in the manufacturing process of printed circuit boards (PCBs). Its main function is to accurately transfer the circuit design pattern onto the substrate of the PCB. This process typically involves using a light source (such as ultraviolet light) to irradiate the PCB substrate coated with a photosensitive resist (also known as photoresist or dry film). Through the exposure process, a chemical reaction occurs in the resist, thereby forming the required circuit pattern in the developing step.

[0003] A double-sided LDI-RTR exposure machine is an advanced device used in the manufacturing of printed circuit boards (PCBs). It combines laser direct imaging (LDI) technology with roll-to-roll (RTR) processing methods and can perform exposure processing on both sides of the PCB simultaneously. This device is commonly used in the production of high-density interconnect (HDI) boards, flexible printed circuit boards (FPCBs), and multi-layer boards. LDI technology uses a laser to directly image the photosensitive material on the PCB, eliminating the need for traditional film. This can reduce production costs, improve exposure accuracy, and reduce alignment errors. The double-sided LDI-RTR exposure machine controls the illuminance of the semiconductor chip through forward exposure and reverse exposure, thereby achieving higher-quality chip manufacturing. The forward exposure system uses a light source to project light onto the semiconductor material, and the required chip pattern is displayed through a mask. The reverse exposure system then re-irradiates the chip after forward exposure to enhance the exposure effect.

[0004] When an exposure machine is usually in use, the exposure material needs to be placed on a specific suction cup and fixed before exposure can be carried out. When using double-sided glass exposure, the exposure material usually needs to be placed on the lower glass plate, and the substrate material is flattened and fixed by the descent of the upper glass above the exposure material. To achieve the process of simultaneous double-sided exposure of an ultra-long exposure material at one time, when using the prior art to perform the exposure of the exposure material in multiple times, the exposure material is prone to left-right deviation during the winding and unwinding process, resulting in problems such as splicing and misalignment on the exposure material, causing waste of the exposure material, affecting the yield of the exposure process, affecting the user experience, and being unfavorable for the promotion and application of the above exposure machine in the market.

Detailed implementation manners

[0019] To make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be described below through specific embodiments shown in the accompanying drawings. However, it should be understood that these descriptions are only exemplary and do not limit the scope of the present invention. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present invention.

[0020] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the present invention.

[0021] The present invention will be described in detail below with reference to the accompanying drawings.

[0022] Embodiment: As Figures 1 to 3As shown in the figure, a large glass frame automatic lifting and flipping device mainly consists of a support platform 1, an upper glass 2, an upper glass frame 3 for fixing the upper glass 2, a lower glass 4, a lower glass frame 5 for fixing the lower glass 4, a lifting drive mechanism for driving the lifting of the upper glass frame 3, and a flipping drive mechanism for driving the flipping of the upper glass frame 3. The lifting drive mechanism is mainly provided to separate the upper glass 2 from the lower glass 4 so as to place the exposure material to be exposed between the two, or to wind up the material after exposure, etc. During this process, since the sizes of the upper glass 2 and the lower glass 4 in this embodiment are larger than those of the glass in the prior art. Specifically, the size of the upper glass frame 3 can be approximately 800×4000mm, and the size of the lower glass 4 is set to be similar to that of the upper glass frame 3. Similarly, in order to fix the exposure material with a relatively large size, the sizes of the upper glass 2 and the lower glass 4 in this embodiment are set to be similar to that of the upper glass frame 3. In order to ensure the stability of the overall structure of the lifting and flipping device during use, in this embodiment, the lower glass frame 5 is installed on the support platform 1, and the lower glass 4 is fixed on the lower glass frame 5. In the exposure state, the upper glass 2 is located directly above the lower glass 4. In this embodiment, since the sizes of the upper glass 2, the upper glass frame 3, the lower glass 4, and the lower glass frame 5 are larger than those of the fixing device in the prior art, it is possible to perform one-time simultaneous double-sided exposure on the ultra-long exposure material, improve the exposure efficiency while ensuring the exposure quality, and enhance the user experience. During actual exposure operation, the lower glass frame 5 and the lower glass 4 can be fixed. If the exposure material needs to be replaced, only need to drive the upper glass frame 3 through the lifting drive mechanism to separate the upper glass frame 3 from the lower glass frame 5, that is, the upper glass 2 from the lower glass 4, then lay the exposure material flat on the lower glass 4, and finally lower the upper glass 2. The above method is convenient to operate, and compared with the prior art of winding up the exposure material, it can greatly reduce the operation difficulty and enhance the user experience.

[0023] The above-mentioned lifting drive member 1 6 and the above-mentioned lifting drive member 2 7 are respectively located below the above-mentioned upper glass frame 3 and are used to lift the above-mentioned upper glass frame 3 and drive the above-mentioned upper glass 2. In order to enable the above-mentioned upper glass frame 3 and the upper glass 2 in this embodiment to perform stable lifting motion in the vertical direction, the above-mentioned lifting drive mechanism in this embodiment includes a lifting drive member 1 6 and a lifting drive member 2 7. There are multiple lifting drive members 1 6, and multiple above-mentioned lifting drive members 1 6 are arranged at equal intervals along one side of the above-mentioned upper glass frame 3. There are multiple lifting drive members 2 7, and multiple above-mentioned lifting drive members 2 7 are arranged at equal intervals along the other side of the above-mentioned upper glass frame 3. By arranging the lifting drive members at equal intervals on both sides of the upper glass frame 3, the balance of the upper glass frame 3 and the upper glass 2 during the lifting process can be ensured, and tilting or shaking caused by uneven load can be avoided, thereby improving the stability and safety during the lifting process. The above-mentioned lifting drive member 1 6 and the above-mentioned lifting drive member 2 7 are both servo electric cylinders. The servo electric cylinder can provide precise speed control, position control, and thrust control, which is very important for application scenarios that require high-precision positioning. The control accuracy of the servo electric cylinder can reach 0.01 mm, and this high-precision control is difficult to achieve by traditional hydraulic or pneumatic systems. Therefore, it can effectively ensure the stability of the above-mentioned upper glass frame 3 and the above-mentioned upper glass 2 during the lifting process. Compared with hydraulic cylinders and pneumatic cylinders, electric cylinders are more energy-efficient and cleaner, and there is no problem of hydraulic oil leakage, so they are more environmentally friendly. The maintenance cost of electric cylinders is relatively low because they usually only need to be greased regularly and there are no vulnerable parts that need to be replaced frequently, thus reducing the after-sales service cost, etc.

[0024] The above-mentioned support table 1 is provided with an installation through groove 1-1. The above-mentioned lifting drive member 1 6 and the above-mentioned lifting drive member 2 7 are both installed below the above-mentioned support table 1, and the output ends of the above-mentioned lifting drive member 1 6 and the above-mentioned lifting drive member 2 7 are respectively abutted against the lower part of the above-mentioned upper glass frame 3 through the above-mentioned installation through groove 1-1 to realize the lifting operation of the above-mentioned upper glass frame 3. The cross-sectional size of the above-mentioned installation through groove 1-1 is adapted to the cross-sectional sizes of the above-mentioned lifting drive member 1 6 and the above-mentioned lifting drive member 2 7. This setting method is on the one hand to facilitate the installation of the above-mentioned lifting drive member 1 6 and the above-mentioned lifting drive member 2 7, and on the other hand, it can make the overall structure of the device compact. Compared with installing the above-mentioned lifting drive member 1 6 and the above-mentioned lifting drive member 2 7 on the support table 1, the overall height of the device can be reduced, thereby reducing the space occupation.

[0025] In order to realize the flipping operation of the above-mentioned upper glass frame 3, so that the upper glass 2 can be cleaned, maintained or replaced, etc., in this embodiment, a lifting and lifting support block 8 and a lifting and flipping support block 9 are respectively installed on both sides of the above-mentioned upper glass frame 3, and the above-mentioned flipping drive mechanism includes a guide rail 10 and a universal shaft 11 installed below the above-mentioned lifting and lifting support block 8, one end of the above-mentioned universal shaft 11 is fixed to the above-mentioned lifting and lifting support block 8 through the above-mentioned guide rail 10, and the other end of the above-mentioned universal shaft 11 is connected to the output end of the above-mentioned lifting drive member 2 7; the output end of the above-mentioned lifting drive member 1 6 is used to be connected to the above-mentioned lifting and flipping support block 9. In order to increase the contact area between the output end of the lifting drive member 2 7 and the universal shaft 11, the output end of the lifting drive member 2 7 is installed with an electric cylinder connector 12, which is used to connect with the other end of the universal shaft 11. The electric cylinder connector 12 plays a role in receiving and increasing the contact area in this process, thereby ensuring that the force of the lifting drive member 2 7 can act on the electric cylinder connector 12, and then act on the universal shaft 11, to achieve the driving of the universal shaft 11, so that the other end of the universal shaft 11 can slide along the guide rail 10, change the opening size between the upper glass frame 3 and the lower glass frame 5, and then realize the flipping operation of the upper glass frame 3. Specifically, a slider that can slide along the length direction of the guide rail 10 can be installed on the guide rail 10, and one end of the universal shaft 11 is fixed on the slider, so that the wear on the end of the universal shaft 11 can be reduced, the service life of the universal shaft 11 can be ensured, and the cost of replacement and maintenance can be reduced.

[0026] In order to further ensure the stability of the upper glass frame 3 during the flipping process, in this embodiment, the universal shaft 11 is installed on one side of the upper glass frame 3, and a flip fixing seat 13, a flip cylinder 14, a rotating member 15 and a flip support block 17 are also installed on the other side of the upper glass frame 3. The flip fixing seat 13 and the flip cylinder 14 are both installed on the support platform 1, and the flip support block 17 is installed on the upper glass frame 3. The flip fixing seat 13 and the flip support block 17 are both provided with a through hole for the rotating member 15 to pass through. The rotating member 15 is installed at the output end of the flip cylinder 14 for inserting into the flip fixing seat 13 and the flip support block 17 to realize the flipping of the upper glass frame 3. The rotating member 15 can be a pin with a simple structure and high economical practicality. In order to ensure the stability of the flip fixing seat 13 and the flip cylinder 14 during installation and use, the flip fixing seat 13 and the flip cylinder 14 are both installed on the support platform 1. The rotating member 15, i.e., the pin, plays a connecting role and a rotating role in this process.

[0027] The above-mentioned lifting support blocks 8 and the above-mentioned lifting and flipping support blocks 9 are both multiple. The lifting support blocks 8 and the above-mentioned lifting and flipping support blocks 9 are both fixedly connected to the upper glass frame 3, and part of them are located outside the above-mentioned upper glass frame 3. The purpose is to facilitate the driving of the above-mentioned first lifting driving member 6 and the above-mentioned second lifting driving member 7, so as to realize the lifting operation of the upper glass frame 3 relative to the upper glass 2. The number and installation position of the above-mentioned lifting support blocks 8 correspond to the number and installation position of the above-mentioned second lifting driving member 7, and the number and installation position of the above-mentioned lifting and flipping support blocks 9 correspond to the number and installation position of the above-mentioned first lifting driving member 6. In this embodiment, both the above-mentioned lifting support blocks 8 and the above-mentioned lifting and flipping support blocks 9 are five, and are arranged along the length direction of the above-mentioned upper glass frame 3, so as to ensure the stability of the upper glass frame 3 during the lifting process. The above-mentioned lifting support blocks 8 and the above-mentioned lifting and flipping support blocks 9 are respectively arranged on both sides of the above-mentioned upper glass frame 3 and are arranged opposite to each other to ensure balance.

[0028] The above-mentioned upper glass 2 is fixed to the above-mentioned upper glass frame 3 through the fixing plate 16. The fixing plate 16 can provide a stable support for the upper glass 2, ensure its position fixed within the upper glass frame 3, prevent displacement or detachment caused by external force or pressure change, and thus ensure the stability and safety of the entire structure. The fixing plate 16 also helps to evenly distribute the weight of the upper glass 2 onto the upper glass frame 3, reducing structural deformation or damage caused by weight concentration, thus ensuring the service life of the upper glass 2 and reducing the use cost. The above-mentioned fixing plate 16 is L-shaped and is fixed at the corner of the above-mentioned upper glass frame 3. The L-shaped fixing plate can provide better support, increase the connection strength between the glass and the frame, and thus improve the stability and load-bearing capacity of the entire structure. This design helps to disperse the stress generated by the self-weight, wind pressure or temperature change of the glass, reducing the risk of glass breakage. At the same time, the L-shaped fixing plate can also be conveniently docked with the corner of the glass frame, simplifying the installation process. During installation, the accurate placement of the glass can be ensured by adjusting the position of the fixing plate 16, improving the installation efficiency and accuracy. Similarly, the above-mentioned lower glass 4 can be fixed to the above-mentioned lower glass frame 5 through the fixing plate 16.

[0029] The above-mentioned support table 1 is made of marble. Marble has high rigidity and is not easily deformed, which enables the support table 1 to maintain extremely high stability when carrying heavy objects or during the operation of precision instrument equipment. Moreover, marble has the advantages of low thermal expansion coefficient, wear resistance and chemical corrosion resistance, which can effectively ensure the accuracy and durability of the support table 1 during use.

[0030] An automatic lifting and flipping device for a large glass frame in this embodiment. Its lifting working principle is as follows: The lifting support block 8 and the lifting and flipping support block 9 are respectively installed on both sides of the upper glass frame 3 and are fixedly connected to the upper glass frame 3. And a part of the lifting support block 8 and the lifting and flipping support block 9 is located outside the upper glass frame 3, aiming to facilitate the driving of the first lifting driving member 6 and the second lifting driving member 7 thereon, so as to realize the lifting operation of the upper glass frame 3 relative to the upper glass 2.

[0031] An automatic lifting and flipping device for a large glass frame in this embodiment. Its flipping working principle is that the acting force of the second lifting driving member 7 acts on the electric cylinder connecting member 12, and then acts on the universal shaft 11, realizing the driving of the universal shaft 11, so that the other end of the universal shaft 11 can slide along the guide rail 10, thereby changing the inclination angle of the upper glass frame 3 and the opening size between the upper glass frame 3 and the lower glass frame 5, and realizing the flipping operation of the upper glass frame 3.

[0032] Specifically, the flipping action process is as follows: 1). The first lifting driving member 6 and the second lifting driving member 7 move upward simultaneously, so that the central axis of the pin shaft hole position on the flipping fixed seat 13 is on the same horizontal plane as the axis of the lifting and flipping support block 9; 2). The flipping cylinder 14 pushes the rotating member 15, that is, the pin shaft, into the pin shaft hole on the flipping fixed seat 13; 3). The five first lifting driving members 6, that is, the lifting electric cylinders, move downward to return to the origin to reserve space for the flipping action of the upper glass frame 3; 4). The second lifting driving member 7, that is, the lifting electric cylinder, moves upward, pushing the universal shaft 11 upward. At the same time, the universal shaft 11 moves along the length direction of the guide rail 10, and the flipping support block 17 flips relative to the flipping fixed seat 13 to complete the flipping action; 5). The second lifting driving member 7 moves downward to make the upper surface of the lifting support block 8 parallel to the upper surface of the support table 1; 6). The first lifting driving member 6 rises to contact the lifting and flipping support block 9, and the flipping cylinder 14 drives the rotating member 15, that is, the pin shaft, to retract; 7). The first lifting driving member 6 and the second lifting driving member 7 return to the origin position.
