Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of exposure machines, and particularly relates to a large glass frame automatic lifting and overturning device. BACKGROUND

[0002] An exposure machine is a key device used in the manufacturing process of printed circuit boards (PCB), and its main function is to accurately transfer circuit design patterns to the substrate of a PCB. This process usually involves using a light source (such as ultraviolet light) to irradiate a PCB substrate coated with a photosensitive resist (also known as photoresist or dry film), causing the resist to chemically react through the exposure process, thereby forming the desired 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 (PCB), which combines laser direct imaging (LDI) technology with roll-to-roll (RTR) processing, enabling simultaneous exposure processing of both sides of a PCB. This device is commonly used in the production of high-density interconnect (HDI) boards, flexible boards (FPCB), and multi-layer boards. LDI technology uses a laser to directly image on the photosensitive material on a PCB, eliminating the need for traditional film, which reduces production costs, improves exposure accuracy, and reduces alignment errors. A double-sided LDI-RTR exposure machine controls the light intensity of a semiconductor chip through forward exposure and reverse exposure, achieving higher quality chip manufacturing. The forward exposure system uses a light source to project light onto the semiconductor material, displaying the required chip pattern through a mask. The reverse exposure system re-irradiates the chip after forward exposure to enhance the exposure effect.

[0004] During exposure, the exposure machine usually needs to place the exposure material on a special suction cup to fix the exposure material before exposure. When using double-sided glass exposure, the exposure material is usually placed on the lower glass plate, and the upper glass is lowered to flatten and fix the substrate material. To achieve one-time double-sided simultaneous exposure of ultra-long exposure material, using the existing technology to divide the exposure material into multiple exposures, the exposure material is prone to left and right deviation during winding and unwinding, resulting in problems such as splicing and misalignment on the exposure material, causing waste of exposure material, affecting the yield of the exposure process, affecting the user's experience, and not conducive to the promotion and application of the above-mentioned exposure machine in the market.

[0023] The present application will be described in detail below in conjunction with the drawings.

[0024] Embodiment: As Figures 1 to 3As shown, a large glass frame automatic lifting and overturning device mainly comprises a support table 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 driving mechanism for driving the upper glass frame 3 to lift, and a overturning driving mechanism for driving the upper glass frame 3 to overturn. The lifting driving mechanism is mainly used 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 the material after exposure, etc. In this process, the size of the upper glass 2 and the lower glass 4 in the embodiment is larger than that of the glass in the prior art. Specifically, the size of the upper glass frame 3 is about 800*4000mm, and the size of the lower glass 4 is similar to that of the upper glass frame 3. Similarly, in order to fix the large-size exposure material, the size of the upper glass 2 and the lower glass 4 in the embodiment is similar to that of the upper glass frame 3. In order to ensure the stability of the overall structure of the lifting and overturning device during use, the lower glass frame 5 is installed on the support table 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 the embodiment, the size of the upper glass 2, the upper glass frame 3, the lower glass 4 and the lower glass frame 5 is larger than that of the fixing device in the prior art, so that one-time double-sided exposure of the super-long exposure material can be realized, the exposure efficiency is improved, the exposure quality is ensured, and the user experience is enhanced. In actual exposure operation, the lower glass frame 5 and the lower glass 4 can be fixed. If the exposure material needs to be replaced, the upper glass frame 3 is driven by the lifting driving mechanism, the upper glass frame 3 and the lower glass frame 5, i.e. the upper glass 2 and the lower glass 4, are separated, the exposure material is laid on the lower glass 4, and finally the upper glass 2 is lowered. The above-mentioned operation is convenient, and compared with the winding exposure material in the prior art, the operation difficulty is greatly reduced, and the user experience is enhanced.

[0025] The lifting driving member one 6 and the lifting driving member two 7 are respectively located below the upper glass frame 3 for lifting the upper glass frame 3 and driving the upper glass 2. In order to realize the stable lifting movement of the upper glass frame 3 and the upper glass 2 in the vertical direction, the lifting driving mechanism in the embodiment includes the lifting driving member one 6 and the lifting driving member two 7. The lifting driving member one 6 is a plurality of lifting driving members, and the plurality of lifting driving members are equidistantly arranged along one side of the upper glass frame 3. The lifting driving member two 7 is a plurality of lifting driving members, and the plurality of lifting driving members are equidistantly arranged along the other side of the upper glass frame 3. By equidistantly arranging the lifting driving members on both sides of the upper glass frame 3, the balance of the upper glass frame 3 and the upper glass 2 during lifting can be ensured, and tilting or shaking caused by uneven load can be avoided, thereby improving the stability and safety during lifting. The lifting driving member one 6 and the lifting driving member two 7 are both servo electric cylinders, which can provide precise speed control, position control and thrust control, which is very important for applications requiring high precision positioning. The control accuracy of the servo electric cylinder can reach 0.01 mm. This high-precision control is difficult to achieve in traditional hydraulic or pneumatic systems, so the stability of the upper glass frame 3 and the upper glass 2 during lifting can be effectively ensured. The electric cylinder is more energy-saving and cleaner than the hydraulic cylinder and the pneumatic cylinder, and there is no problem of hydraulic oil leakage, so it is more environmentally friendly. The maintenance cost of the electric cylinder is low, because it usually only needs regular grease lubrication, and there is no need to frequently replace the vulnerable parts, thereby reducing the after-sales service cost.

[0026] The support table 1 is provided with a mounting through slot 1-1, and the lifting driving member one 6 and the lifting driving member two 7 are both installed below the support table 1, and the output ends of the lifting driving member one 6 and the lifting driving member two 7 are both abutted below the upper glass frame 3 through the mounting through slot 1-1, so as to realize the lifting operation of the upper glass frame 3. The cross-sectional size of the mounting through slot 1-1 is matched with the cross-sectional size of the lifting driving member one 6 and the lifting driving member two 7. This kind of setting mode is on one hand to facilitate the installation of the lifting driving member one 6 and the lifting driving member two 7, and on the other hand can make the overall structure of the device compact, compared with installing the lifting driving member one 6 and the lifting driving member two 7 on the support table 1, the height of the overall device can be reduced, and the space occupation can be reduced.

[0027] In order to realize the turnover operation of the upper glass frame 3, so as to clean, maintain or replace the upper glass 2 and the like, the lifting lifting support block 8 and the lifting turnover support block 9 are respectively arranged on the two sides of the upper glass frame 3 in the embodiment. The turnover driving mechanism includes the guide rail 10 and the universal shaft 11 arranged below the lifting lifting support block 8. One end of the universal shaft 11 is fixed to the lifting lifting support block 8 through the guide rail 10. The other end of the universal shaft 11 is connected with the output end of the lifting driving part two 7. The output end of the lifting driving part one 6 is used to be connected with the lifting turnover support block 9. In order to increase the contact area between the output end of the lifting driving part two 7 and the universal shaft 11, the output end of the lifting driving part two 7 is provided with the electric cylinder connecting piece 12. The electric cylinder connecting piece 12 is used to be connected with the other end of the universal shaft 11. The electric cylinder connecting piece 12 plays a role of receiving and increasing the contact area in the process, so as to ensure that the force of the lifting driving part two 7 can act on the electric cylinder connecting piece 12, and then act on the universal shaft 11, realize the driving of the universal shaft 11, and make the other end of the universal shaft 11 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 turnover operation of the upper glass frame 3. Specifically, the sliding block capable of sliding along the length direction of the guide rail 10 can be arranged on the guide rail 10. One end of the universal shaft 11 is fixed to the sliding block, so as to reduce the abrasion of the end of the universal shaft 11, ensure the service life of the universal shaft 11, and reduce the cost of replacement and maintenance.

[0028] In order to further ensure the stability of the upper glass frame 3 in the turnover process, the universal shaft 11 is arranged on one side of the upper glass frame 3 in the embodiment. The turnover fixing seat 13, the turnover cylinder 14, the rotating part 15 and the turnover support block 17 are further arranged on the other side of the upper glass frame 3. The turnover fixing seat 13 and the turnover cylinder 14 are arranged on the support table 1. The turnover support block 17 is arranged on the upper glass frame 3. The turnover fixing seat 13 and the turnover support block 17 are provided with the through hole through which the rotating part 15 passes. The rotating part 15 is arranged on the output end of the turnover cylinder 14 and is used to be inserted into the turnover fixing seat 13 and the turnover support block 17, so as to realize the turnover of the upper glass frame 3. The rotating part 15 can be the pin shaft which has simple structure and high economy and practicability. In order to ensure the stability of the turnover fixing seat 13 and the turnover cylinder 14 in the process of installation and use, the turnover fixing seat 13 and the turnover cylinder 14 are arranged on the support table 1. The pin shaft plays a connecting role and a rotating role at the same time in the process.

[0029] The lifting support blocks 8 and the overturning support blocks 9 are fixedly connected with the upper glass frame 3 and partially located outside the upper glass frame 3, which is convenient for the driving of the lifting driving member 6 and the lifting driving member 7, thereby realizing the lifting operation of the upper glass frame 3 on the upper glass 2. The number and installation position of the lifting support blocks 8 correspond to the number and installation position of the lifting driving member 7, and the number and installation position of the overturning support blocks 9 correspond to the number and installation position of the lifting driving member 6. In the embodiment, the number of the lifting support blocks 8 and the overturning support blocks 9 is five, which are arranged along the length direction of the upper glass frame 3, thereby ensuring the stability of the upper glass frame 3 during lifting.

[0030] The upper glass 2 is fixed on the upper glass frame 3 by the fixing plate 16, which can provide stable support for the upper glass 2, ensure the position of the upper glass 2 in the upper glass frame 3, prevent displacement or falling due to external force or pressure change, and thereby 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 to the upper glass frame 3, reduces the structural deformation or damage caused by weight concentration, thereby ensuring the service life of the upper glass 2 and reducing the use cost. The fixing plate 16 is L-shaped and fixed at the corner of the upper glass frame 3. The L-shaped fixing plate can provide better support, increase the connection strength between the glass and the frame, thereby improve the stability and carrying capacity of the entire structure. This design helps to disperse the stress generated by the weight of the glass, wind pressure or temperature change, reduces the risk of glass breakage. At the same time, the L-shaped fixing plate can be conveniently butted with the corner of the glass frame, simplifying the installation process. During installation, the position of the fixing plate 16 can be adjusted to ensure accurate placement of the glass, improving installation efficiency and accuracy. Similarly, the lower glass 4 can be fixed on the lower glass frame 5 by the fixing plate 16.

[0031] The support table 1 is made of marble, which has high rigidity and is not easy to deform, which makes the support table 1 maintain high stability during carrying heavy objects or during the operation of precision instruments and equipment. Marble has low thermal expansion coefficient, wear resistance and chemical corrosion resistance, which can effectively ensure the precision and durability of the support table 1 during use.

[0032] The lifting principle of the automatic large glass frame lifting and overturning device in the embodiment is that the lifting and overturning support blocks 8 and 9 are respectively installed on the two sides of the upper glass frame 3 and are fixedly connected with the upper glass frame 3, and the lifting and overturning support blocks 8 and 9 are partially located outside the upper glass frame 3, so that the lifting driving member one 6 and the lifting driving member two 7 can drive the lifting and overturning support blocks 8 and 9, thereby realizing the lifting operation of the upper glass frame 3 relative to the upper glass 2.

[0033] The overturning principle of the automatic large glass frame lifting and overturning device in the embodiment is that the force of the lifting driving member two 7 is applied to the electric cylinder connecting member 12 and then to the universal shaft 11, thereby driving 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 overturning operation of the upper glass frame 3.

[0034] Specifically, the overturning action flow is as follows:

[0035] 1) The lifting driving member one 6 and the lifting driving member two 7 move upward at the same time, so that the center axis of the pin shaft hole on the overturning fixed seat 13 is on the same horizontal plane as the axis of the lifting and overturning support block 9.

[0036] 2) The overturning cylinder 14 pushes the rotating member 15, i.e. the pin shaft, to be inserted into the pin shaft hole on the overturning fixed seat 13.

[0037] 3) The five lifting driving members one 6, i.e. the lifting cylinders, move downward to the original position, thereby reserving space for the overturning action of the upper glass frame 3.

[0038] 4) The lifting driving member two 7, i.e. the lifting cylinder, moves upward, thereby pushing the universal shaft 11 to move upward, and at the same time, the universal shaft 11 moves along the length direction of the guide rail 10, and the overturning support block 17 moves relative to the overturning fixed seat 13 to complete the overturning action.

[0039] 5) The lifting driving member two 7 moves downward, so that the upper surface of the lifting and overturning support block 8 is parallel to the upper surface of the support table 1.

[0040] 6) The lifting driving member one 6 moves upward to contact the lifting and overturning support block 9, and the overturning cylinder 14 drives the rotating member 15, i.e. the pin shaft, to retreat.

[0041] 7) The lifting driving member one 6 and the lifting driving member two 7 return to the original position.

[0042] The large glass frame automatic lifting and overturning device has the advantages of ingenious structure, convenient operation, and the like, and can effectively guarantee the stability of the exposure material in the exposure process by placing the exposure material between the upper glass 2 and the lower glass 4, and can realize the quick separation between the upper glass 2 and the lower glass 4 by setting the lifting driving mechanism, thereby improving the winding and unwinding rate of the exposure material, reducing the probability of problems such as splicing and misplacement of the exposure material, reducing the waste of the exposure material, guaranteeing the yield of the exposure process, thereby reducing the use cost, enhancing the use experience of the user, and being favorable to the promotion and application of the large glass frame automatic lifting and overturning device in the exposure machine technical field.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein can be applied to other embodiments without departing from the spirit or scope of the application; thus, the present application is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
