Abstract
Description
Technical Field
[0001] The invention relates to the field of teaching aids, and in particular to an image developing device used for holographic photography dry plate image developing teaching. Background Art
[0002] The basic principle of holographic photography is to use laser as the illumination source and divide the light emitted by the light source into two beams: one beam is directly directed to the photosensitive film, and the other beam is reflected by the object and then directed to the photosensitive film. The two beams of light are superimposed on the photosensitive film to produce interference, and the interference fringes formed contain the amplitude and phase information of the object, thereby recording the hologram of the object.
[0003] Since holographic equipment is relatively expensive, in order to let students deepen their understanding of the characteristics of optical waves through holographic experiments, the holographic process is roughly divided into three parts during the teaching process: light path design, image development and image viewing. In the two parts of light path design and image viewing, teachers can provide guidance and corrections on site, which are basically quite complete. Now we need to present the teaching environment of image development to students. The dry plate used as the photosensitive film needs to be developed. The image development process requires multiple passes through the developer, stop solution, fixer and bleaching solution for development and fixing.
[0004] The specific operation is as follows: put the holographic dry plate into the developer for a few minutes, then rinse it, then take it out and put it into the fixer, take it out and rinse it, then put the holographic dry plate into the bleach and let it stand for a few minutes, and finally rinse and blow dry the holographic dry plate.
[0005] In the current teaching experiment environment, the boxes of developer, fixer and other solutions are placed on the table of the laboratory table. There are many participants in a test class and the test environment must be operated in a dim environment, which makes the current holographic projection image washing test teaching have the following problems: 1. First of all, students need to be taken to a room that can be protected from light to perform experimental operations in a special room. This requires students to be taken to a special laboratory during class on weekdays, resulting in a waste of time for students to move to the laboratory to study. 2. Learning to conduct experiments in a dim environment, the chemical reagents used in the experiment are expensive and can only be contained in a small basin, resulting in multiple students crowding in front of a small water box, and the experimental operation space is limited, resulting in low student participation. 3. During the experiment, many students used tweezers to take the dry plate out of the developer and fixer. Due to their unskilled movements and the influence of the dark environment, it took too long, which led to excessive development of the dry plate. 4. Some students do not operate in a standardized manner. They do not follow the standardized steps and directly take the dry plate out of the developer with their hands, which causes the developer to be contaminated. 5. The timing of the operation is not well grasped. After the development is completed, the dry plate cannot be quickly separated from the developer, resulting in over-development of the holographic dry plate.
[0006] The above problems are all difficult to solve in the current holographic projection image washing teaching. There is an urgent need for a new teaching aid or method to change the traditional holographic projection image washing teaching process. Summary of the invention
[0007] The present invention aims to provide an image developing device for teaching holographic imaging dry plate image developing, by which the image developing device simulates various operation steps of actual image developing process, so that the experimenter can better understand the actual situation in holographic imaging.
[0008] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: an image developing device for teaching holographic dry plate image developing, comprising a light-proof box, a box door for opening the box is arranged on one side of the box, a rotating disk is installed at the bottom of the box, a plurality of circumferentially arranged independent image developing bins are fixed on the surface of the rotating disk, an electric push rod is installed on the inner wall of the box just above the image developing bin, a developing frame is connected below the electric push rod, the developing frame comprises a supporting frame, a plurality of clamping frames for fixing the dry plates are arranged on one side of the supporting frame, the clamping frames are arranged downwardly and inclined toward the outside of the supporting frame, the clamping frames comprise a clamping frame bottom edge for clamping the bottom edge of the dry plate, and a clamping frame side edge for clamping the side edge of the dry plate, the clamping frame bottom edge and the clamping frame side edge both have upper and lower layers.
[0009] This image washing device is used as a holographic projection image washing teaching principle: The exposed dry plate is inserted into the card rack from one side of the opening of the card rack, so that the upper and lower edges, side edges and bottom edges of the dry plate are fixed, so that the dry plate will not shake or fall off during the image development process. The image development chambers are concentrated on a rotating disk, and developer, fixer, bleaching solution and cleaning water are added to different image development chambers. Through the rotation of the rotating disk, the image development chambers with different solutions are rotated to the bottom of the card rack as needed. The dry plate is fixed on the card rack, and the card rack is fixed on the support frame. The support frame is quickly moved up and down by an electric push rod, so that the dry plate can be quickly immersed in or out of the image development chamber solution. When the image development is completed, the dry plate is dried, and a holographic image will appear on the dry plate.
[0010] The advantages of using this image washing device as a holographic projection image washing teaching are: 1. This device integrates the hardware of the entire image development process into a box. The dry plate used in the teaching demonstration is a 5cm*10cm rectangular plate. The image development device is a box with a volume of no more than 1 cubic meter. The entire image development device can be moved to the classroom, so that students participating in the experiment no longer need to go to a special laboratory to participate in the experimental learning.
[0011] 2. This solution further considers that the circumferential space of the developing chamber for accommodating dry plates is reduced due to the reduction in the size of the entire developing device. Therefore, in order to reduce the lateral distance of the dry plates, this solution only sets a bracket on one side of the support frame, and makes the bracket tilt downward. When the dry plates are inserted into the bracket, the tail of the dry plates is outside the bracket, and the tail and head of the dry plates will be as close to the support frame as possible, so that the longitudinal occupation of the dry plates is increased and the lateral occupation is reduced; so that the support frame after the dry plates are inserted can be completely immersed in the solution of the developing chamber.
[0012] 3. In order to make students understand the steps of developing images in class, during the teaching demonstration, the developer and fixer reagents are not added to the developing chamber temporarily, so that the developer and fixer are no longer affected by light. At this time, the cabinet door is open, and students can directly observe the steps of the developing process.
[0013] 4. During the image development process, close the cabinet door to keep the cabinet in a completely dark room state, so that the final imaging effect is better than the imaging effect of personnel operating in a dim light environment.
[0014] 5. By controlling the rotation of the image-washing chamber and the upward and downward extension of the electric push rod, the steps of developing, fixing, bleaching and cleaning are automatically realized. The experimental teachers and students do not touch the image-washing solution. By controlling the upward and downward extension of the electric push rod, the holographic dry plate can be quickly separated from the developer after the development is completed, avoiding the over-development of other holographic dry plates due to unskilled removal operation.
[0015] 6. Clamp the dry plate on the bracket. The bracket structure is a two-layer structure to limit the upper and lower positions of the dry plate. The side and bottom of the bracket limit the side and bottom of the dry plate respectively. The bracket fixes the position of the dry plate from five directions. The bracket is tilted and shows a downward trend under the action of gravity, which also consolidates the limiting effect. Even if the dry plate is washed by the solution in the washing chamber, it still remains in a fixed state.
[0016] 7. Both the support frame and the card frame are frame structures, which make the surface of the dry plate exposed as much as possible, so that the dry plate can fully contact with the developing solution during the developing process. This avoids the problem of directly placing multiple dry plates in the developing chamber, which causes the dry plate part to not fully contact with the developing solution, resulting in poor development.
[0017] Preferably, the inner walls of the side and bottom of the card frame are provided with guide grooves, and the guide grooves pass through the side or bottom, and the guide grooves on the side of the card frame are arranged to be inclined outward. During the image development process, the card frame is lowered to immerse all the dry plates in the image development solution, especially when immersed in the developer, because the time of immersion in the developer needs to be controlled, which is actually to control the residual time of the developer on the dry plate. When the dry plate is lifted from the developer, the developer remaining on the card frame will quickly flow out from the guide groove, avoiding the problem of excessive development at the edge of the dry plate caused by the developer remaining at the edge of the card frame.
[0018] Preferably, the plurality of card racks are arranged in parallel with each other, and the inclination angle between the card racks and the support frame is less than 30°; since the developing chamber is concentrated on the rotating table, after the volume of a single developing chamber is reduced, it is necessary to develop multiple dry plates, so the plurality of card racks are arranged in parallel, and the inclination angle between the card racks and the support frame is less than 30°, which also allows the dry plates to be closer to the support frame, reduces the lateral distance of the support frame, and can ensure that the dry plates are completely immersed in the developing solution.
[0019] Preferably, a dryer for drying the dry plates is also installed in the box, and the air outlet of the dryer faces the side of the card rack.
[0020] The dry plates that have been developed are dried by the dryer. Because the card racks are arranged in parallel and the edges of the card racks are designed with guide grooves, the dryer dries the dry plates from the sides. The wind flows between the parallel dry plates, driving the water flow away. At the same time, the wind passes through the guide grooves to complete the drying of the edges of the dry plates.
[0021] Preferably, the box wall is provided with heat dissipation holes, a heat dissipation fan is installed on the heat dissipation holes, a shading plate is installed on the heat dissipation holes, and a gap is left between the shading plate and the heat dissipation fan; so that the gas blown out of the dryer can be discharged from the heat dissipation holes, and external light is prevented from entering through the heat dissipation holes to cause failure of dry plate development.
[0022] Preferably, the rotating disk is driven by a servo motor in forward and reverse rotation. By controlling the forward and reverse rotation amount of the servo motor, the rotating disk is vibrated back and forth, allowing the developer in the developing chamber to flow back and forth, so that the developing components in the developer can fully contact the surface of the dry plate, thereby achieving rapid development.
[0023] Preferably, the box body also includes an independent chamber for installing electrical components, the dryer is also installed in the chamber, and the chamber is provided with a guide hole for allowing the air outlet of the dryer to face the direction of the dry plate. In this way, the dryer and the electrical components are in independent chambers, which can prevent the solution splashed from the developing chamber from damaging the electrical components, and also prevent the indicator light on the electrical components from interfering with the development.
[0024] Preferably, in order to facilitate the demonstration of each step of developing the image, all side walls of the box are independently hinged to the top surface, so that the box can be completely opened, allowing the experimenter to directly observe the movement process in the box.
[0025] The present invention provides a control system for rhythmically controlling the image developing process, including a turntable motor for driving a container to rotate, a push rod motor for driving an electric push rod, a dryer for drying dry plates, a cooling fan for dissipating heat in a box, a PLC controller for action control, and a touch screen for controlling signal input, wherein the PLC controller stores an executable image developing process control program; the touch screen communicates bidirectionally with the PLC, and an execution button for controlling the PLC to execute a separate stage of the image developing step separately is provided in the touch screen, and a configuration screen for displaying an animation of the image developing process is also stored in the touch screen; the turntable motor, the push rod motor, the dryer and the cooling fan are all connected to the signal output end of the PLC controller.
[0026] During the automatic image development process, all the dry plates completed by holographic photography are first inserted into the card rack, and developer, fixer, bleach and cleaning water are added to the image development chamber respectively. The box is closed and the execution button on the touch screen is clicked. The PLC controller will execute the program stored in it and make the turntable motor, push rod motor, dryer and cooling fan perform corresponding actions according to the program steps.
[0027] In order to be used as a teaching demonstration, the present application enables the control system to automatically complete the entire image washing step and to control each individual step in the control method. The specific control method includes: designing an automatic execution button in the touch screen to allow the PLC controller to automatically execute the image washing process, including the following steps; Step 1: The PLC controller drives the turntable motor and the card holder to return to the initial position; Step 2: After a delay, the PLC controls the turntable motor to drive the developing chamber containing the developer to move to the bottom of the support frame, and the PLC drives the card frame to move down quickly, so that the dry plate is immersed in the developer to complete the development. After the development is completed, the PLC drives the card frame to move up quickly, so that the dry plate leaves the developing chamber containing the developer; Step 3: PLC controls the turntable motor to drive the washing bin containing clean water to rotate to the bottom of the support frame, and PLC drives the card rack to move down quickly, so that the dry plate is immersed in the clean water to clean the residual developer. After the cleaning is completed, PLC drives the card rack to move up quickly, so that the dry plate leaves the washing bin containing clean water; Step 4: PLC controls the turntable motor to drive the image-washing bin containing fixer to move to the bottom of the support frame. PLC drives the card frame to move down quickly again, so that the dry plate is immersed in the fixer to complete the fixing. After the fixing is completed, PLC drives the card frame to move up quickly again, so that the dry plate leaves the image-washing bin containing fixer. Step 5: PLC controls the turntable motor to drive the washing bin containing bleach to move to the bottom of the support frame. PLC drives the bracket to move down quickly again, so that the dry plate can be immersed in clean water to clean the residual fixing solution. After the fixing solution is cleaned, PLC drives the bracket to move up quickly again, so that the dry plate can leave the washing bin containing clean water. Step 6: PLC controls the dryer to dry the dry plate. After drying, the whole image washing process is completed; Design a manual execution button on the touch screen that can execute the above steps 2 to 6 separately. Click the manual execution button of any step and the PLC controller will execute the action of the corresponding step. BRIEF DESCRIPTION OF THE DRAWINGS
