Description

Technical Field

[0001] The invention relates to the technical field of exposure machines, in particular to an automatic lifting and flipping device for a large glass frame. Background Art

[0002] Exposure machine is a key equipment used in the printed circuit board (PCB) manufacturing process. Its main function is to accurately transfer the circuit design pattern to the substrate of the PCB. This process usually involves using a light source (such as ultraviolet light) to irradiate the PCB substrate coated with photosensitive resist (also known as photoresist or dry film). The exposure process causes the resist to react chemically, thereby forming the desired circuit pattern in the development step.

[0003] The double-sided LDI-RTR exposure machine is an advanced equipment used in the manufacture of printed circuit boards (PCBs). It combines laser direct imaging (LDI) technology with roll-to-roll (RTR) processing to expose both sides of the PCB at the same time. This equipment is commonly used in the production of high-density interconnect (HDI) boards, flexible boards (FPCBs), and multi-layer boards. LDI technology uses lasers to directly image the photosensitive material on the PCB without the use of traditional film, which can reduce production costs, improve exposure accuracy, and reduce alignment errors. The double-sided LDI-RTR exposure machine controls the illumination of semiconductor chips 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 desired chip pattern is displayed through the mask. The reverse exposure system re-irradiates the chip after the forward exposure to enhance the exposure effect.

[0004] When exposing, the exposure machine usually needs to place the exposure material on a specific suction cup and fix the exposure material before exposure. When double-sided glass exposure is used, the exposure material usually needs to be placed on the lower glass plate, and the upper glass above the exposure material is lowered to flatten and fix the substrate material. In order to achieve a one-time double-sided exposure process of ultra-long exposure materials, when the exposure material is divided into multiple exposures in the prior art, the exposure material is prone to left and right deviations during the winding and unwinding process, resulting in splicing, misalignment and other problems on the exposure material, resulting in waste of exposure materials, affecting the yield of the exposure process, affecting the user experience, and is not conducive to the promotion and application of the above-mentioned exposure machine in the market.

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention is described below by the specific embodiments shown in the accompanying drawings. However, it should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present invention.

[0020] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

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

[0022] Example: Figures 1 to 3As shown, a large glass frame automatic lifting and flipping device is mainly composed 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 upper glass frame 3 to rise and fall, and a flipping drive mechanism for driving the upper glass frame 3 to flip. The setting of the lifting drive mechanism is mainly to achieve the separation between the upper glass 2 and the lower glass 4, so that the exposure material to be exposed can be placed between the two, or the exposed material can be rolled up, etc. In this process, since the sizes of the upper glass 2 and the lower glass 4 in this embodiment are larger than those 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 the size of the upper glass frame 3. Similarly, in order to be able to fix larger exposure materials, the sizes of the upper glass 2 and the lower glass 4 in this embodiment are set to be similar to the size 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 realize one-time and simultaneous double-sided exposure of the super-long exposure material, improve the exposure efficiency while ensuring the exposure quality, and enhance the user experience. In the actual exposure operation, the lower glass frame 5 and the lower glass 4 can be fixed. If the exposure material is to be replaced, it is only necessary to drive the upper glass frame 3 through the lifting and driving mechanism to realize the separation between the upper glass frame 3 and the lower glass frame 5, that is, the upper glass 2 and the lower glass 4, and then lay the exposure material flat on the lower glass 4, and finally lower the upper glass 2. The above method is easy to operate, and compared with the winding exposure material in the prior art, it can greatly reduce the difficulty of operation and enhance the user experience.

[0023] The lifting drive member 1 6 and the lifting drive member 2 7 are respectively located below the upper glass frame 3 to lift the upper glass frame 3 and drive the upper glass 2. In order to achieve the stable lifting movement of the upper glass frame 3 and the upper glass 2 in the vertical direction in this embodiment, the 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 the multiple lifting drive members 1 6 are equidistantly arranged along one side of the upper glass frame 3. There are multiple lifting drive members 2 7, and the multiple lifting drive members 2 7 are equidistantly arranged along the other side of the upper glass frame 3. By equidistantly arranging the lifting drive members 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 the tilting or shaking caused by uneven load can be avoided, thereby improving the stability and safety during the lifting process. The lifting drive member 1 6 and the lifting drive member 2 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 0.01mm. This high-precision control is difficult to achieve with traditional hydraulic or pneumatic systems. Therefore, it can effectively ensure the stability of the upper glass frame 3 and the upper glass 2 during the lifting process. Compared with hydraulic cylinders and air cylinders, electric cylinders are more energy-saving and clean, and there is no problem of hydraulic oil leakage, so they are more environmentally friendly. The maintenance cost of electric cylinders is low because they usually only require regular grease lubrication, and there are no wearing parts that need to be replaced frequently, thereby reducing after-sales service costs.

[0024] The support platform 1 is provided with a mounting slot 1-1, and the lifting drive member 1 6 and the lifting drive member 2 7 are both mounted below the support platform 1, and the output ends of the lifting drive member 1 6 and the lifting drive member 2 7 are both abutted against the bottom of the upper glass frame 3 through the mounting slot 1-1, so as to realize the lifting operation of the upper glass frame 3. The cross-sectional size of the mounting slot 1-1 is matched with the cross-sectional size of the lifting drive member 1 6 and the lifting drive member 2 7. This arrangement is not only convenient for the installation of the lifting drive member 1 6 and the lifting drive member 2 7, but also can make the overall structure of the device compact. Compared with mounting the lifting drive member 1 6 and the lifting drive member 2 7 on the support platform 1, the height of the device as a whole can be reduced, thereby reducing the space occupied.

[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] There are multiple lifting and lifting support blocks 8 and lifting and flipping support blocks 9. Both the lifting support blocks 8 and the lifting and flipping support blocks 9 are fixedly connected to the upper glass frame 3, and are partially located outside the upper glass frame 3. The purpose is to facilitate the lifting drive member 1 6 and the lifting drive member 2 7 to drive them, so as to realize the lifting operation of the upper glass frame 3 on the upper glass 2. The number and installation position of the lifting and lifting support blocks 8 correspond to the number and installation position of the lifting drive member 2 7, and the number and installation position of the lifting and flipping support blocks 9 correspond to the number and installation position of the lifting drive member 1 6. In this embodiment, there are five lifting and lifting support blocks 8 and five lifting and flipping support blocks 9, which are arranged along the length direction of the upper glass frame 3, so as to ensure the stability of the upper glass frame 3 during the lifting process. The lifting and lifting support blocks 8 and the lifting and flipping support blocks 9 are respectively arranged on both sides of the upper glass frame 3 and are arranged opposite to each other to ensure balance.

[0028] The upper glass 2 is fixed on the upper glass frame 3 through a fixing plate 16. The fixing plate 16 can provide a stable support for the upper glass 2, ensure that its position in the upper glass frame 3 is fixed, and prevent displacement or falling off due to external force or pressure changes, thereby ensuring 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, reduce structural deformation or damage caused by weight concentration, thereby ensuring the service life of the upper glass 2 and reducing the cost of use. The fixing plate 16 is L-shaped and fixed at the corners 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 improving the stability and bearing capacity of the entire structure. This design helps to disperse the stress generated by the glass due to its own weight, wind pressure or temperature changes, and reduce the risk of glass breakage. At the same time, the L-shaped fixing plate can also be conveniently docked with the corners of the glass frame to simplify the installation process. During installation, the position of the fixing plate 16 can be adjusted to ensure the accurate placement of the glass, thereby improving the installation efficiency and accuracy. Similarly, the lower glass 4 can be fixed on the lower glass frame 5 through the fixing plate 16.

[0029] The above-mentioned support platform 1 is made of marble, which has high rigidity and is not easy to deform, so that the support platform 1 can maintain extremely high stability when carrying heavy objects or during the operation of precision instruments and equipment. 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 platform 1 during use.

[0030] The present embodiment is a large glass frame automatic lifting and flipping device, and its lifting working principle is: 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 the lifting support block 8 and the lifting and flipping support block 9 are partially located outside the upper glass frame 3, the purpose is to facilitate the lifting drive member 1 6 and the lifting drive member 2 7 to drive them, thereby realizing the lifting operation of the upper glass frame 3 on the upper glass 2.

[0031] The present embodiment is a large glass frame automatic lifting and flipping device, and its flipping working principle is that the force of the above-mentioned lifting drive member 27 acts on the above-mentioned electric cylinder connecting member 12, and then acts on the above-mentioned universal shaft 11, so as to drive the above-mentioned universal shaft 11, so that the other end of the above-mentioned universal shaft 11 can slide along the above-mentioned guide rail 10, thereby changing the inclination angle of the above-mentioned 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: 1) The lifting drive member 1 6 and the lifting drive member 2 7 move upward simultaneously, so that the central axis of the pin hole on the flip fixing seat 13 and the axis of the lifting and flipping support block 9 are in the same horizontal plane; 2) The turning cylinder 14 pushes the rotating member 15, i.e. the pin shaft, to be inserted into the pin shaft hole on the turning fixing seat 13; 3) The five lifting drive members 6, i.e., the lifting electric cylinders, move downward and return to the origin, leaving space for the upper glass frame 3 to flip; 4) The lifting drive member 2 7, i.e., the lifting electric cylinder, moves upward, pushing the universal shaft 11 to move upward. At the same time, the universal shaft 11 moves along the length direction of the guide rail 10, and the flip support block 17 flips relative to the flip fixing seat 13 to complete the flipping action; 5) The lifting driving member 2 7 moves downward, so that the upper surface of the lifting support block 8 is parallel to the upper surface of the support platform 1; 6) The lifting drive member 6 rises and contacts the lifting and flipping support block 9, and the flip cylinder 14 drives the rotating member 15, i.e. the pin shaft, to retreat; 7) The lifting drive member 1 6 and the lifting drive member 2 7 return to their original positions.

[0033] In the present embodiment, a large glass frame automatic lifting and flipping device is cleverly structured and easy to operate. By setting up a large glass frame, the exposure material is placed between the upper glass 2 and the lower glass 4, which can effectively ensure the stability of the exposure material during the exposure process; by setting up a lifting drive mechanism, the upper glass 2 and the lower glass 4 can be quickly separated, thereby increasing the speed of winding and unwinding the exposure material, reducing the probability of splicing, misalignment and other problems of the exposure material, reducing the waste of exposure materials, ensuring the yield of the exposure process, thereby reducing the cost of use, enhancing the user experience, and being conducive to the promotion and application of the above-mentioned large glass frame automatic lifting and flipping device in the field of exposure machine technology.
