Description
Technical Field
[0001] The utility model relates to the technical field of exposure machines, in particular to an automatic CCD exposure machine for production and processing of PCB substrates with an early warning function. Background Art
[0002] CCD exposure machine is a photolithography equipment used to manufacture high-precision PCB substrates. It is mainly used in the manufacturing process of the inner layer of PCB. The working principle of CCD exposure machine involves multiple key components, including CCD camera, light source, optical system, motion system and control system. During the working process, the light emitted by the light source passes through the optical system and projects the image onto the CCD camera, thereby achieving high-precision image transfer and exposure. This equipment is particularly suitable for inner and outer layer processes. It has the characteristics of 4CCD alignment system, UVLED dot matrix parallel light source, and high resolution. It can achieve ultra-low power consumption of about 3 kWh per hour while ensuring high precision. CCD exposure machine plays a vital role in PCB manufacturing, improving production efficiency and product quality through automation and precise technology. PCB substrate exposure is a key step used to accurately transfer the design pattern to the PCB surface to form the required conductive circuit and component pattern.
[0003] When the exposure machine is exposing the PCB substrate, the PCB substrate needs to be accurately positioned and placed on the exposure machine for exposure. Some exposure machines lack measures for accurately positioning the PCB substrate. When the PCB substrate is positioned and placed for exposure, the staff is often required to manually adjust the position of the PCB board, which is cumbersome to adjust. In addition, the staff can only roughly align the PCB substrate during the self-adjustment process, and the positioning and placement effect is not good, which in turn affects the production efficiency of the PCB substrate. Utility Model Content
[0004] The purpose of the utility model is to provide an automatic CCD exposure machine for PCB substrate production and processing with an early warning function, so as to solve the problems raised in the above-mentioned background technology.
[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:
[0006] An automatic CCD exposure machine for PCB substrate production and processing with an early warning function comprises an exposure machine body, a placement plate, four protective shells, and four positioning components.
[0007] A placement plate is arranged on the lower surface of the exposure machine body; four protective shells are respectively fixedly installed on the four ends of the placement plate surface; four positioning components are respectively arranged inside each protective shell; the positioning component includes a driving motor, a threaded rod 1, a bevel gear 1, a bevel gear 2, a threaded rod 2, and two moving blocks; one end of the threaded rod 1 is fixedly connected to the output end of the driving motor, and the other end is fixedly connected to the bevel gear 1, the bevel gear 1 is meshed with the bevel gear 2, the bevel gear 2 is fixedly connected to the threaded rod 2, and the two ends of the threaded rod 2 are respectively rotatably connected to the inner wall of the protective shell, and the surfaces of the threaded rod 1 and the threaded rod 2 are both movably sleeved with moving blocks.
[0008] By adopting the above technical solution, four positioning components are set in this solution, so that the PCB substrate can be positioned before exposure, and the exposure effect can be prevented from being affected by the placement deviation of the PCB substrate.
[0009] The further improvement of the technical solution of the utility model is that it also includes a slide plate 1, which is fixedly installed on the surface of one of the moving blocks; and a sliding groove 1 which is slidably connected to the slide plate 1 is opened on one side of the protective shell.
[0010] The above technical solution is adopted. In this solution, when the slide plate 1 is driven to move to position one side of the PCB substrate, it can slide inside the slide groove 1, and the size of the opening inside the slide groove 1 meets the moving range of the slide plate 1.
[0011] A further improvement of the technical solution of the utility model is that it also includes a second slide plate, which is fixedly mounted on the surface of another moving block; a second slide groove slidably connected to the second slide plate is provided on the other side of the protective shell, and a fixed plate slidably connected to the first slide plate is provided on the surface of the second slide plate.
[0012] The above-mentioned technical solution is adopted. In this solution, when the slide plate 2 is driven to move, it can slide inside the sliding groove 2. At this time, the sliding groove 2 can limit the moving range of the slide plate 2, and the slide plates 1 and 2 can be used together for sliding. The slide plate 1 can slide in the fixed plate opened on the surface of the slide plate 2.
[0013] A further improvement of the technical solution of the utility model is that a clamping groove is installed at the bottom end of each slide plate two.
[0014] By adopting the above technical solution, the fixing plates connected to the two bottom ends of the slide plate in this solution can push the PCB substrate placed on the placement plate, so as to locate the position of the PCB substrate.
[0015] A further improvement of the technical solution of the utility model is that an auxiliary push plate is installed at one end of a bottom side of each slide plate.
[0016] The above technical solution is adopted, in which the auxiliary push plate is installed at one end of the bottom side of the slide plate 1, which does not affect the staggered movement between the slide plate 1 and the slide plate 2. The auxiliary push plate can push and position the side of the PCB substrate.
[0017] A further improvement of the technical solution of the utility model is that a displacement sensor is installed on the upper surface of the exposure machine body.
[0018] By adopting the above technical solution, the displacement sensor in this solution can detect the position of the PCB substrate placed on the placement plate. When the position of the PCB substrate is not at the center corresponding to the exposure device or is offset, the displacement sensor can detect it and transmit the information to the terminal device.
[0019] A further improvement of the technical solution of the utility model is that an alarm is installed at one end of the surface of the exposure machine body.
[0020] By adopting the above technical solution, the displacement sensor in the solution can transmit the position deviation information of the detected PCB substrate to the alarm, so that the alarm generates an alarm to remind the staff to place the offset.
[0021] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:
[0022] 1. The utility model provides an automated CCD exposure machine for PCB substrate production and processing with an early warning function. By arranging a displacement sensor on the exposure machine body and using an alarm in conjunction with the same, the position of the PCB substrate can be detected when the staff is exposing the PCB substrate, and an alarm can be triggered for the PCB board that is placed offset to achieve a reminder operation, thereby avoiding a large number of substrates being placed offset when exposing the PCB substrate, which affects the exposure effect.
[0023] 2. The utility model provides an automated CCD exposure machine for PCB substrate production and processing with an early warning function. By setting four positioning components, an offset PCB substrate can be positioned, and the PCB substrate can be placed in the center position under the exposure device, thereby greatly improving the production efficiency of the PCB substrate.

[0032] The present invention is further described in detail below in conjunction with the embodiments:
[0033] Example 1
[0034] like Figure 1-6 As shown, the utility model provides an automatic CCD exposure machine for PCB substrate production and processing with an early warning function, including an exposure machine body 1, a placement plate 4, four protective shells 5, and four positioning components 6.
[0035] The placement plate 4 is arranged on the lower surface of the exposure machine body 1 ; four protective shells 5 are fixedly mounted on four ends of the surface of the placement plate 4 .
[0036] Four positioning components 6 are respectively arranged inside each protective shell 5; the positioning component 6 includes a driving motor 601, a threaded rod 1 602, a bevel gear 1 603, a bevel gear 2 604, a threaded rod 2 605, and two moving blocks 606; one end of the threaded rod 1 602 is fixedly connected to the output end of the driving motor 601, and the other end is fixedly connected to the bevel gear 1 603, the bevel gear 1 603 is meshed with the bevel gear 2 604, the bevel gear 2 604 is fixedly connected to the threaded rod 2 605, and the two ends of the threaded rod 2 605 are respectively rotatably connected to the inner wall of the protective shell 5, and the surfaces of the threaded rod 1 602 and the threaded rod 2 605 are movably sleeved with moving blocks 606.
[0037] In this embodiment, the PCB substrate 9 can be placed on the surface of the placement plate 4 for exposure, and protective shells 5 are respectively installed at the four ends of the surface of the placement plate 4. Positioning components 6 are respectively provided inside the protective shells 5. The protective shells 5 can protect the installation of the positioning components 6. When the PCB substrate 9 is placed on the placement plate 4 for exposure, the PCB substrate 9 may be offset out of the exposure device due to operational errors, thereby affecting the exposure effect of the PCB substrate 9. At this time, the four driving motors 601 can be started synchronously, and the four driving motors 601 can operate synchronously and drive the threaded rod 602 to reverse Rotate, at this time, since one end of the threaded rod 1 602 is fixedly connected to the bevel gear 1 603, the bevel gear 1 603 can drive the bevel gear 2 604 to rotate synchronously, and similarly the threaded rod 2 605 also rotates in the opposite direction. At this time, the threaded rod 1 602 and the moving blocks 606 on the threaded rod 2 605 can slide synchronously, and the sliding speed and distance are consistent. Under the action of each sliding moving block 606, the four corners of the PCB substrate 9 can be pushed and positioned relative to each other, so that the PCB substrate 9 can be located at the center of the placement plate 4, which is convenient for being in a good exposure position, and the exposure effect of the PCB substrate 9 can be improved.
[0038] like Figure 1-6 As shown, in this embodiment, preferably, a slide plate 7 is further included, which is fixedly mounted on the surface of one of the moving blocks 606; a sliding groove 501 is provided on one side of the protective shell 5 to be slidably connected to the slide plate 7. Since the slide plate 7 is fixedly connected to the moving block 606, when the moving block 606 moves, the slide plate 7 moves along with the moving block 606, and the sliding groove 501 provided on one side of the protective shell 5 can just meet the moving range of the slide plate 7, so that the slide plate 7 can push and position the position of the PCB substrate 9 during the movement, and the sliding groove 501 can limit the sliding of the slide plate 7, so that the movement of the slide plate 7 can be more stable.
[0039] like Figure 1-6As shown, preferably, it also includes a slide plate 2 8, which is fixedly mounted on the surface of another moving block 606; the other side of the protective shell 5 is provided with a sliding groove 2 502 which is slidably connected to the slide plate 2 8, and the surface of the slide plate 2 8 is provided with a fixed plate 801 which is slidably connected to the slide plate 1 7. Slide plate 2 8 is fixedly connected to another moving block 606. When the moving block 606 moves, slide plate 2 8 moves along with it, and slide plate 2 8 can slide inside the sliding groove 2 502. The size of the inside of the sliding groove 2 502 is just enough to allow slide plate 2 8 to slide, and the sliding groove 2 502 can limit the sliding of slide plate 2 8, so that the sliding of slide plate 2 8 can be more stable, and slide plate 1 7 and slide plate 2 8 can slide synchronously and staggered. When sliding staggered, slide plate 1 7 will slide inside the fixed plate 801. The fixed plate 801 can position the moving distance of slide plate 1 7 and clamp its inside on the surface of slide plate 1 7, so that the staggered sliding between slide plate 1 7 and slide plate 2 8 is not hindered, and the sliding between slide plate 1 7 and slide plate 2 8 can form a consistent right-angle mechanism for the four corners of the PCB substrate 9, so that slide plate 1 7 and slide plate 2 8 can fit on the side of the PCB substrate 9 during the sliding process to push and position it, which can drive the PCB substrate 9 to the center position of the placement plate 4, thereby facilitating exposure and improving the production efficiency of the PCB substrate 9.
[0040] like Figure 1-6 As shown, preferably, a snap-in groove 802 is installed at the bottom end of each slide plate 2 8. The snap-in groove 802 is connected to the bottom end of the slide plate 2 8, and the snap-in groove 802 and the slide plate 2 8 are in the same horizontal line. When the slide plate 2 8 slides to position the side of the PCB substrate 9, the fixing plate 801 will fit on the side of the PCB substrate 9, so that when the slide plate 2 8 moves, the fixing plate 801 can push the PCB substrate 9 to be positioned at the center position, and the fixing plate 801 does not completely fit on the surface of the placement plate 4, and will not scratch and wear the surface of the placement plate 4.
[0041] like Figure 1-6 As shown, preferably, an auxiliary push plate 701 is installed at one end of the bottom side of each slide plate 7. Since the slide plate 1 7 and the slide plate 2 8 slide crosswise, when the slide plate 1 7 slides, it will slide inside the fixed plate 801. When the side of the PCB substrate 9 is pushed and positioned, the auxiliary push plate 701 can push the side of the PCB substrate 9 within a small angle between the slide plate 1 7 and the slide plate 2 8. Because the slide plate 1 7 is in a certain suspended state, the auxiliary push plate 701 can play a role in positioning and pushing the PCB substrate 9.
[0042] like Figure 1-6As shown, preferably, a displacement sensor 2 is installed on the upper surface of the exposure machine body 1. The displacement sensor 2 is mainly used to detect the displacement or position of the PCB substrate 9, and can detect whether the PCB substrate 9 is placed at the specified position. If the PCB substrate 9 is not placed at the center position, the displacement sensor 2 can detect this displacement and transmit the information of the displaced PCB substrate 9 to the control terminal.
[0043] like Figure 1-6 As shown, preferably, an alarm 3 is installed at one end of the surface of the exposure machine body 1. The alarm 3 is used in conjunction with the displacement sensor 2. When the displacement sensor 2 detects that the PCB substrate 9 is not in the center position, the displacement sensor 2 cooperates with the alarm 3 to convey the information and trigger an alarm signal, thereby reminding the operator that the PCB substrate 9 is not placed in the appropriate position, which can achieve an effective reminder to facilitate the correction of the operator's operation.
[0044] The following is a detailed description of the working principle of the automatic CCD exposure machine for PCB substrate production and processing with early warning function.
[0045] like Figure 1-6As shown, when in use, the PCB substrate 9 can be placed on the placement plate 4. After placement, the displacement sensor 2 can detect whether the placed PCB substrate 9 is in the center position of the placement plate 4. Since the center position of the placement plate 4 is used in conjunction with the exposure device on the upper surface of the exposure machine body 1, a better exposure effect can be achieved. Therefore, the information of the PCB substrate 9 with position displacement detected by the displacement sensor 2 will be transmitted to the control terminal. The information after transmission will trigger the alarm signal on the alarm 3. The alarm signal generated by the alarm 3 can remind the operator that the PCB substrate 9 is not placed accurately, so as to correct the operator's next placement. When it is inconvenient for the operator to manually adjust the PCB substrate 9 to a suitable position, the displacement information detected by the displacement sensor 2 can be transmitted to the control terminal. At this time, the control terminal can synchronously start the four drive motors 601, and the four drive motors 601 operate synchronously and drive the threaded rod 1 602 to rotate, and the bevel gear 1 603 and the bevel gear 2 604 rotate. 04 meshing can perform synchronous rotation operation, at this time, the threaded rod 2 605 and the threaded rod 1 602 can be driven at the same speed, and the two moving blocks 606 located on the threaded rod 1 602 and the threaded rod 2 605 can also move synchronously. At this time, the slide plate 1 7 and the slide plate 2 8 can cross-move under the action of the two moving blocks 606, so that the slide plate 1 7 and the slide plate 2 8 form an angle with the four ends of the PCB substrate 9, so that the position of the placed PCB substrate 9 can be moved relative to the center position, so that the four ends of the PCB substrate 9 are all pushed synchronously, and then the PCB substrate 9 generates a uniform driving force, and the PCB substrate 9 will not be pushed out of the exposure position. By setting four positioning components 6 to drive the slide plate 1 7 and the slide plate 2 8 to position the PCB substrate 9, the offset PCB substrate 9 can be positioned and placed, so that the PCB substrate 9 is in the center position of the placement plate 4, thereby achieving a good exposure effect and improving the production efficiency of the PCB substrate 9.
[0046] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
