Description

Technical Field

[0001] This invention relates to the field of material collection devices, and more specifically to a collection device for copper-clad ceramic substrates based on ceramic resistors. Background Technology

[0002] Ceramic resistors use special ceramic materials with high stability and high reliability as the substrate. A resistive film layer is formed on the surface of the ceramic substrate through a specific process, and a resistive element is formed by adding leads, etc. It has the characteristics of high temperature resistance and good high frequency performance. Ceramic substrate copper cladding is a process of attaching copper foil to the ceramic substrate through bonding and electroplating processes to make a substrate with specific circuit functions.

[0003] In the process of copper cladding on ceramic substrates, due to the small size and large quantity of ceramic substrates, manual collection is inefficient and easily causes damage or contamination to the ceramic substrates. Therefore, it is necessary to collect and transport batches of ceramic substrates. In the ceramic substrate collection and transport devices currently in use, after the ceramic substrates are discharged, they are often directly transferred to the conveyor belt equipment by using a limiting structure such as an inclined plate. For example, a ceramic substrate collection device for copper cladding on ceramic substrates disclosed in Chinese Patent Publication No. CN110844480B can also be used to complete the transportation and collection of ceramic substrates by using an intelligent suspended material conveying system in conjunction with the conveyor belt equipment. In the process of transferring ceramic substrate materials using a limiting structure, the ceramic substrate inevitably experiences relative friction with the limiting structure or direct collision with the conveyor belt, which can easily cause damage to the surface of the ceramic substrate and affect the product quality. Moreover, the output quantity of ceramic substrates is variable. When the output quantity is large, if the conveyor belt speed cannot be slowed down in time, the ceramic substrates will accumulate during the collection process, affecting the conveying and collection efficiency. When the output quantity is small, if the conveyor belt continues to transport at a slow speed, it will significantly increase the time cost of conveying and collecting the ceramic substrates. Summary of the Invention

[0004] In view of the above-mentioned shortcomings of the prior art, the present invention provides a collection device for copper-clad ceramic substrates based on ceramic resistors. It can effectively solve the problems in the prior art that the ceramic substrate will have relative friction with the limiting structure or direct collision with the conveyor belt during the material transfer process, which affects the product quality of the ceramic substrate. In addition, the conveying speed of the conveyor belt cannot be adaptively adjusted according to the output quantity of the ceramic substrate, which easily affects the conveying and collection efficiency of the ceramic substrate and increases the time cost of conveying and collecting the ceramic substrate.

[0005] To achieve the above objectives, the present invention provides the following technical solution: This invention provides a collection device for copper-clad ceramic substrates based on ceramic resistors, comprising: The material conveying frame and the material discharging platform are fitted together. An electric conveyor belt is rotatably installed on the side wall of the material conveying frame. A non-destructive material transfer component is rotatably connected to the two opposing side walls of the material discharging platform. The non-destructive material transfer assembly includes two rotating shafts rotatably connected to two opposing sidewalls of the discharge platform. Each of the two rotating shafts has a supporting rotating frame fixedly connected to its outer periphery. A rotating rod is rotatably connected to the upper end of each of the two supporting rotating frames. A suspension bracket is rotatably connected to the outer periphery of each rotating rod via a lubricated bearing. Two sliding frames are fixedly connected to the lower end face of the suspension bracket. Two sliding rods are slidably connected to the inner sides of each of the two sliding frames. A straight plate is fixedly connected between the two sliding rods on the same side. A retractable adsorption airbag is fixedly connected between the two straight plates. The bottom end of the retractable adsorption airbag has several adsorption mesh holes. An adaptive adsorption component is fixedly connected to the upper end face of the suspension bracket. This adaptive adsorption component detects the distribution of ceramic substrates above the discharge platform and adaptively adjusts the adsorption range of the retractable adsorption airbag. A conveying speed regulating component is fixedly connected to the outer wall of the suspension bracket. This conveying speed regulating component adaptively adjusts the conveying speed of the electric conveyor belt according to the number of ceramic substrates. A support platform is fixedly connected to the inner side of the material conveying frame. A floating material assembly is provided on the upper surface of the support platform, and a dispensing and collection assembly is fixedly connected to the upper surface of the material conveying frame.

[0006] Furthermore, the non-destructive material transfer assembly also includes a fixed bracket fixedly connected to the outer wall of the discharge platform. A servo motor is fixedly installed on the upper surface of the fixed bracket, and the servo motor is fixedly connected to the end of the rotating shaft.

[0007] Furthermore, the electric conveyor belt includes a drive motor, a drive roller, a driven roller, and a conveyor belt. The conveyor belt is a Teflon mesh conveyor belt. The drive roller and the driven roller are rotatably connected to the side wall of the material conveying frame, and the drive roller and the driven roller are connected by transmission through the conveyor belt. The drive motor is fixedly installed on the outer wall of the material conveying frame, and the output end of the drive motor is fixedly connected to the wheel axle of the drive roller. The support platform is located inside the conveyor belt.

[0008] Furthermore, the adaptive adsorption component includes two vacuum pumps fixedly connected to the upper surface of the suspension bracket. Each of the two vacuum pumps is fixedly connected to an air extraction pipe. Two small electric push rods are fixedly connected to the outer walls of the two sliding frames. The telescopic end of each small electric push rod is fixedly connected to the ends of two straight plates. A vision sensor is fixedly connected to the upper part of the outer wall of the discharge platform. The vision sensor is used to monitor the distribution of ceramic substrates above the discharge platform in real time. A PLC controller is fixedly installed on the outer wall of the discharge platform. The PLC controller, the vision sensor, and several small electric push rods are electrically connected to an external power supply.

[0009] Furthermore, the conveying speed regulating component includes a concave bracket fixedly connected to the outer wall of the suspension bracket, and a variable resistance rod fixedly connected to the inner side of the concave bracket, wherein the telescopic ends of the two small electric push rods are fixedly connected to sliding plates. The variable resistance rod and the two sliders constitute a sliding rheostat. The sliding rheostat, the drive motor, and the external power supply form a closed series circuit. During the process of the two sliders moving in opposite directions, the resistance value of the variable resistance rod in the closed series circuit of the sliding rheostat, the drive motor, and the external power supply decreases.

[0010] Furthermore, a pressure switch is fixedly connected to the outer wall of one of the supporting rotating frames. The pressure switch is used to control the start and stop of the two vacuum pumps. An arc-shaped abutment is fixedly connected to the outer wall of the discharge platform. The pressure switch and the arc-shaped abutment selectively contact and press together.

[0011] Furthermore, the floating material assembly includes an air duct opened on the upper surface of the support platform, and several micro fans are fixedly installed on the inner wall of the air duct. Air inlets are opened on the side wall of the support platform and the side wall of the material conveying frame.

[0012] Furthermore, the dispensing and collecting assembly includes two docking guide rails fixedly connected to the upper end face of the conveying frame, a collecting frame slidably connected to the inner side of the two docking guide rails, a plurality of guide strips fixedly connected to the upper end face of the collecting frame, the plurality of guide strips and the upper end face of the collecting frame forming a plurality of collecting troughs, and a plurality of soft limiting rollers rotatably connected to the upper end face of the collecting frame via pins.

[0013] The technical solution provided by this invention has the following advantages compared with the known prior art: 1. In this invention, a non-destructive material transfer component is set up. By driving the support rotating frame to slowly reciprocate within a certain range, the rotating rod and the suspension bracket reciprocate as a whole. When the retractable adsorption airbag contacts and adheres to the ceramic substrate, the vacuum pump can draw air from the inside of the retractable adsorption airbag through the air extraction pipe, so that a negative pressure environment is formed inside the retractable adsorption airbag and at several adsorption meshes at its bottom end, so as to fully adsorb and fix the ceramic substrate. After the ceramic substrate is adsorbed and fixed at the bottom end of the retractable adsorption airbag, the rotating shaft continues to rotate in the opposite direction. When the support rotating frame moves the retractable adsorption airbag and the adsorbed and fixed ceramic substrate to the top of the conveyor belt, the retractable adsorption airbag automatically stops adsorbing the ceramic substrate and releases the ceramic substrate to the top of the conveyor belt, thereby avoiding wear on the ceramic substrate during the transfer to the conveyor belt and realizing automated non-destructive material transfer of the ceramic substrate. 2. During the adsorption and fixation of the ceramic substrate by the retractable adsorption airbag, the vision sensor can monitor the distribution of the ceramic substrate above the discharge platform in real time, and change the extension and contraction stroke of the retractable adsorption airbag according to the distribution of the ceramic substrate to adjust the overall adsorption range at the bottom of the retractable adsorption airbag. Thus, the adsorption and fixation range of the retractable adsorption airbag on the ceramic substrate can be adaptively adjusted according to the distribution of the ceramic substrate, ensuring that the discharged ceramic substrate can be transferred and transported, and also helping to maintain the adsorption force of the retractable adsorption airbag on the ceramic substrate. 3. During the movement of two straight plates driven by several small electric push rods, two of the small electric push rods also drive two sliding plates to move, so that the two sliding plates can slide relative to the variable resistance rod in opposite directions or back to back. When there are a large number of ceramic substrates on the discharge platform, that is, when the distribution area of ​​the ceramic substrates is large, the two small electric push rods will push the two sliding plates to move back to back, which will increase the power of the drive motor. This will enable the electric conveyor belt to transport a large number of ceramic substrates at a slower conveying speed, thereby avoiding the accumulation of ceramic substrates during the collection process and ensuring the conveying and collection efficiency of ceramic substrates. Conversely, when there are a small number of ceramic substrates on the discharge platform, the electric conveyor belt will transport a small number of ceramic substrates at a faster conveying speed, which will help reduce the time cost of ceramic substrate conveying and collection. 4. The floating material component in this invention can deliver air force to the top of the air duct through several micro fans during the release of the ceramic substrate by the retractable adsorption airbag. The air force can directly act on the ceramic substrate in the release state above the conveyor belt, thereby providing an upward pushing and buffering effect for the ceramic substrate during the release process, preventing the ceramic substrate from directly colliding with the running conveyor belt, thereby further avoiding wear on the ceramic substrate and ensuring the product quality of the ceramic substrate. 5. In this invention, a sorting and collection component is provided. During the process of conveying ceramic substrates by the electric conveyor belt, the ceramic substrates will continue to move above the sorting frame under the driving force and inertial force of the conveyor belt due to the fit between the end of the collection frame and the surface of the conveyor belt. Several soft limiting rollers and several guide strips can limit the ceramic substrates, so that the ceramic substrates can smoothly enter several collection troughs on the sorting frame. The ceramic substrates collected later can push the ceramic substrates that have entered the collection troughs first, so that multiple ceramic substrates can be neatly arranged in the collection troughs, thereby enabling the sorting and collection of ceramic substrates.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0018] The present invention will be further described below with reference to embodiments.

[0019] Example: Refer to Figures 1 to 9 A collection device for copper-clad ceramic substrates based on ceramic resistors includes: a feeding frame 1 and a discharging platform 2. The feeding frame 1 and the discharging platform 2 are fitted together. An electric conveyor belt 3 is rotatably mounted on the side wall of the feeding frame 1. The electric conveyor belt 3 includes a drive motor 31, a drive roller 32, a driven roller 33, and a conveyor belt 34. The conveyor belt 34 is a Teflon mesh conveyor belt. The drive roller 32 and the driven roller 33 are rotatably connected to the side wall of the feeding frame 1, and the drive roller 32 and the driven roller 33 are connected by transmission through the conveyor belt 34. The drive motor 31 is fixedly mounted on the outer wall of the feeding frame 1. The drive motor 31 is a variable frequency motor of model YZPSL132S-4. The output end of the drive motor 31 is fixedly connected to the wheel axle of the drive roller 32. Two opposing side walls of the discharging platform 2 are rotatably connected to a non-destructive material transfer assembly 4. The non-destructive material transfer assembly 4 includes: Two rotating shafts 41 are rotatably connected to the two opposing side walls of the discharge platform 2. A supporting rotating frame 42 is fixedly connected to the outer peripheral wall of each of the two rotating shafts 41. A rotating rod 43 is rotatably connected to the upper end of each of the two supporting rotating frames 42. A suspension bracket 44 is rotatably connected to the outer peripheral wall of the rotating rod 43 through a lubricating bearing. Two sliding frames 45 are fixedly connected to the lower end face of the suspension bracket 44. Two sliding rods 46 are slidably connected to the inner side of each of the two sliding frames 45. A straight plate 47 is fixedly connected between the two sliding rods 46 on the same side. A retractable adsorption airbag 48 is fixedly connected between the two straight plates 47. Several adsorption mesh holes are opened at the bottom end of the retractable adsorption airbag 48. The non-destructive material transfer assembly 4 also includes a fixed bracket 49 fixedly connected to the outer wall of the discharge platform 2. A servo motor 410 is fixedly installed on the upper end face of the fixed bracket 49. The servo motor 410 is fixedly connected to the end of the rotating shaft 41. Specifically, the retractable adsorption airbag 48 is made of highly elastic silicone material, which has high wear resistance and tensile strength ≥5MPa. It has also undergone pre-stretching treatment, initially stretching to 1.2 times its original length. When the distance between the two straight plates 47 is at its minimum, the bottom of the retractable adsorption airbag 48 remains flat even when it is contracted to its limit. This means that the bottom of the retractable adsorption airbag 48 can always adhere to the ceramic substrate to fully adsorb the ceramic substrate. Specifically, the suspension bracket 44 rotates on the rotating rod 43 via a lubricated bearing. The two vacuum pumps 51 enable the suspension bracket 44 to have sufficient weight as a whole. Therefore, during the swinging process of the supporting rotating frame 42 and the rotating rod 43, the suspension bracket 44 can always remain in a horizontal state, so as to smoothly adsorb, fix and release the ceramic substrate. Specifically, when the retractable adsorption airbag 48 releases the ceramic substrate, the retractable adsorption airbag 48 does not come into contact with the surface of the conveyor belt 34, so as to avoid the retractable adsorption airbag 48 causing motion interference to the operation of the electric conveyor belt 3 and ensure the material conveying stability of the electric conveyor belt 3. By controlling the servo motor 410 to drive the rotating shaft 41 to periodically rotate forward and backward by a certain angle, the supporting rotating frame 42 slowly reciprocates within a certain range, which in turn drives the rotating rod 43 and the suspension bracket 44 to reciprocate as a whole. When the retractable adsorption airbag 48 contacts and adheres to the ceramic substrate, the air inside the retractable adsorption airbag 48 can be drawn out by the vacuum pump 51 and the air extraction pipe 52, so that a negative pressure environment is formed inside the retractable adsorption airbag 48 and at several adsorption mesh holes at its bottom, which fully adsorbs and fixes the ceramic substrate. The ceramic substrate is adsorbed and fixed to the retractable airbag. After the bottom of the retractable adsorption airbag 48 is reduced, the rotating shaft 41 continues to rotate in the opposite direction, causing the supporting rotating frame 42 to swing in the opposite direction and gradually move closer to the electric conveyor belt 3. When the supporting rotating frame 42 moves to the point where the touch switch 10 no longer contacts and presses against the arc-shaped abutment 11, the touch switch 10 controls the two vacuum pumps 51 to shut down, so that the retractable adsorption airbag 48 stops adsorbing the ceramic substrate and releases the ceramic substrate above the conveyor belt 34 to avoid wear on the ceramic substrate during the transfer to the conveyor belt, thus realizing the automated and non-destructive transfer of the ceramic substrate. An adaptive adsorption component 5 is fixedly connected to the upper end face of the suspension bracket 44. This component detects the distribution of ceramic substrates above the discharge platform 2 and adaptively adjusts the adsorption range of the retractable adsorption bladder 48. The adaptive adsorption component 5 includes two vacuum pumps 51 fixedly connected to the upper end face of the suspension bracket 44. One of these pumps has a pressure switch 10 fixedly connected to the outer wall of the rotating support 42. The pressure switch 10 controls the start and stop of the two vacuum pumps 51. The pressure switch 10 is a spring-reset microswitch. An arc-shaped abutment plate 11 is fixedly connected to the outer wall of the discharge platform 2. The pressure switch 10 selectively contacts and presses against the arc-shaped abutment plate 11. Both vacuum pumps 51 and the retractable adsorption bladder 48 are fixedly connected by suction pipes 52. Two small electric push rods 53 are fixedly connected to the outer wall of the moving frame 45. The telescopic end of each small electric push rod 53 is fixedly connected to the ends of two straight plates 47 respectively. A vision sensor 54 is fixedly connected to the upper part of the outer wall of the discharge platform 2. The vision sensor 54 is used to monitor the distribution of ceramic substrates above the discharge platform 2 in real time. A PLC controller 55 is fixedly installed on the outer wall of the discharge platform 2. The PLC controller 55, the vision sensor 54, and several small electric push rods 53 are electrically connected to an external power supply. A dual-camera vision system is adopted to collect the position, spacing and distribution density data of the ceramic substrates in real time. The sensor transmits the image data to the PLC controller 55, and the built-in algorithm of the PLC controller 55 calculates the coverage area of ​​the ceramic substrates. Specifically, the two small electric push rods 53 located on the same side of the straight plate 47 can operate synchronously under the command control of the PLC controller 55 to ensure the stability of the expansion and contraction of the retractable adsorption airbag 48. The visual sensor 54 can monitor the distribution of ceramic substrates above the discharge platform 2 in real time, and change the extension and contraction stroke of the retractable adsorption airbag 48 according to the distribution of ceramic substrates. This allows for adjustment of the overall adsorption range at the bottom of the retractable adsorption airbag 48, thus adaptively adjusting the adsorption fixation range of the retractable adsorption airbag 48 on the ceramic substrates according to the distribution of ceramic substrates. This ensures that the discharged ceramic substrates can be transferred and transported, and also helps maintain the adsorption force of the retractable adsorption airbag 48 on the ceramic substrates. Specifically, the vision sensor 54 employs a dual-camera vision system to calculate the coverage area of ​​the ceramic substrate using an image recognition algorithm.

[0020] A conveying speed regulating component 6 is fixedly connected to the outer wall of the suspension bracket 44. The conveying speed regulating component 6 is used to adaptively adjust the conveying speed of the electric conveyor belt 3 according to the number of ceramic substrates. The conveying speed regulating component 6 includes a concave bracket 61 fixedly connected to the outer wall of the suspension bracket 44. A variable resistance rod 62 is fixedly connected to the inner side of the concave bracket 61. The telescopic ends of the two small electric push rods 53 are fixedly connected to the sliders 63. The variable resistance rod 62 and the two sliders 63 constitute a sliding rheostat. The sliding rheostat, the drive motor 31 and the external power supply form a closed series circuit. During the back-to-back movement of the two sliders 63, the resistance value of the variable resistance rod 62 in the closed series circuit of the sliding rheostat, the drive motor 31 and the external power supply decreases. Specifically, two resistance coils are wound on the variable resistor rod 62, and two sliders 63 are connected in series by wires. The two sliders 63 are in contact with the two resistance coils on the variable resistor rod 62 respectively, so that when the two sliders 63 move in opposite directions, the resistance value of the variable resistor rod 62 in the closed series circuit of the sliding rheostat, the drive motor 31 and the external power supply becomes smaller. During the movement of the two straight plates 47 driven by several small electric push rods 53, two of the small electric push rods 53 also drive two sliding plates 63 to move. When there are a large number of ceramic substrates on the discharge platform 2, that is, when the distribution area of ​​the ceramic substrates is large, the two small electric push rods 53 will push the two sliding plates 63 to move in opposite directions. This makes the resistance value of the variable resistance rod 62 in the closed series circuit composed of the variable resistance rod 62, the two sliding plates 63, the drive motor 31 and the external power supply smaller, and the input current of the drive motor 31 increases, increasing the power. This allows the electric conveyor belt 3 to transport a large number of ceramic substrates at a slower conveying speed, thereby avoiding the accumulation of ceramic substrates during the collection process and ensuring the conveying and collection efficiency of ceramic substrates. Conversely, when there are fewer ceramic substrates on the discharge platform 2, the electric conveyor belt 3 will transport a small number of ceramic substrates at a faster conveying speed, which helps to reduce the time cost of conveying and collecting ceramic substrates.

[0021] A support platform 7 is fixedly connected to the inner side of the material conveying frame 1. The support platform 7 is located inside the conveyor belt 34. A floating material assembly 8 is provided on the upper end face of the support platform 7. The floating material assembly 8 includes an air duct 81 opened on the upper end face of the support platform 7. Several micro fans 82 are fixedly installed on the inner wall of the air duct 81. Air inlets 83 are opened on the side wall of the support platform 7 and the side wall of the material conveying frame 1. Specifically, the micro fan 82 adopts a DC micro fan of model XY-3015. Several micro fans 82 can generate a small amount of wind force when running synchronously. Under the obstruction of the conveyor belt 34, the upward buffer force on the ceramic substrate when it is released is ≤0.1N. The wind force generated by several micro fans 82 is not enough to cause the ceramic substrate to flip or tilt. It only provides a certain buffering effect to ensure the conveying stability of the ceramic substrate. Several miniature fans 82 deliver airflow directly above the air duct 81. This airflow acts directly on the ceramic substrate that is being released above the conveyor belt 34, providing an upward pushing and buffering effect to the ceramic substrate during the release process. This prevents the ceramic substrate from directly colliding with the running conveyor belt 34, thereby further avoiding wear on the ceramic substrate and ensuring the product quality of the ceramic substrate.

[0022] A dispensing and collecting component 9 is fixedly connected to the upper end face of the conveying frame 1. The dispensing and collecting component 9 includes a collecting frame 92 fixedly connected to the upper end face of the conveying frame 1. A plurality of guide strips 93 are fixedly connected to the upper end face of the collecting frame 92. The plurality of guide strips 93 and the upper end face of the collecting frame 92 form a plurality of collecting troughs 94. A plurality of soft limiting rollers 95 are rotatably connected to the upper end face of the collecting frame 92 through a pin. Specifically, the side of the collecting frame 92 is set with an inclined structure, and the lower end face of the collecting frame 92 is close to but not attached to the surface of the conveyor belt 34. The distance between the lower end face of the collecting frame 92 and the surface of the conveyor belt 34 is much smaller than the thickness of the ceramic substrate, so that the ceramic substrate can smoothly enter the collecting frame 92. Specifically, the surfaces of the collecting frame 92 and several guide strips 93 are coated with a lubricating coating to reduce the friction generated during the collection and dispensing of the ceramic substrate and avoid affecting the quality of the ceramic substrate. Specifically, the soft limiting roller 95 is made of silicone rubber, which has excellent elasticity and deformation ability. When the ceramic substrate comes into contact with and squeezes the soft limiting roller 95, the soft limiting roller 95 will deform and roll relative to the ceramic substrate. This not only corrects and limits the ceramic substrate, but also prevents the ceramic substrate from being worn. A pin 12 is slidably connected through the top of the docking guide rail 91, and an insertion hole 13 is opened at the top of the collecting frame 92. The insertion and engagement of the pin 12 and the insertion hole 13 can facilitate the fixing of the collecting frame 92 and the docking guide rail 91, so as to ensure the stability and continuity of the ceramic substrate collected on the collecting frame 92.

[0023] The working principle of this invention is as follows: In use, the ceramic substrate is moved to the top of the discharge platform 2 via the discharge equipment. The servo motor 410 drives the rotating shaft 41 to rotate periodically in both directions at a certain angle, causing the supporting rotating frame 42 to slowly oscillate within a certain range. This, in turn, drives the rotating rod 43 and the suspension bracket 44 to oscillate back and forth as a whole. When the retractable adsorption airbag 48 contacts and adheres to the ceramic substrate, the vacuum pump 51 draws air from inside the retractable adsorption airbag 48 through the suction pipe 52, creating a negative pressure environment inside the retractable adsorption airbag 48 and at several adsorption mesh openings at its bottom. Since the ceramic substrate is under standard atmospheric pressure, it can be absorbed through the external air pressure. The air pressure pushes the ceramic substrate, so that the retractable adsorption airbag 48 can fully adsorb and fix the ceramic substrate using several adsorption mesh holes. After the ceramic substrate is adsorbed and fixed at the bottom of the retractable adsorption airbag 48, the servo motor 410 continues to drive the rotating shaft 41 to rotate in the opposite direction, so that the support rotating frame 42 swings in the opposite direction and gradually moves closer to the electric conveyor belt 3. When the support rotating frame 42 moves to the point where the touch switch 10 no longer contacts and squeezes the arc-shaped plate 11, the touch switch 10 controls the two vacuum pumps 51 to shut down, so that the retractable adsorption airbag 48 stops adsorbing the ceramic substrate and releases the ceramic substrate above the conveyor belt 34. During the process of adsorbing and fixing the ceramic substrate, the visual sensor 54 can monitor the distribution of the ceramic substrate above the discharge platform 2 in real time and transmit a signal to the PLC controller 55 according to the distribution of the ceramic substrate. This allows the PLC controller 55 to control the operation of several small electric push rods 53, which in turn push the two straight plates 47 to move, thereby changing the extension and contraction stroke of the retractable adsorption airbag 48. This allows the overall adsorption range at the bottom of the retractable adsorption airbag 48 to be adjusted, thus adaptively adjusting the adsorption and fixing range of the retractable adsorption airbag 48 on the ceramic substrate according to the distribution of the ceramic substrate. During the movement of two straight plates 47 driven by several small electric push rods 53, two of the small electric push rods 53 also drive two sliding plates 63 to move, allowing the two sliding plates 63 to slide relative to the variable resistance rod 62 in opposite or opposite directions. When there are many ceramic substrates above the discharge platform 2, that is, when the distribution area of ​​the ceramic substrates is large, the two small electric push rods 53 will push the two sliding plates 63 to move in opposite directions, causing the resistance value of the variable resistance rod 62 in the closed series circuit composed of the variable resistance rod 62, the two sliding plates 63, the drive motor 31, and the external power supply to decrease. According to Ohm's law, when the total current in a closed series circuit increases, the input current of the drive motor 31 increases, and the power increases, so that the drive motor 31 can drive the active roller 32 to rotate at a faster speed. This allows the electric conveyor belt 3 to transport a large number of ceramic substrates at a slower conveying speed. Conversely, when the number of ceramic substrates on the discharge platform 2 is small, the two small electric push rods 53 will drive the two sliding plates 63 to move in opposite directions, which reduces the power of the drive motor 31. This means that the electric conveyor belt 3 will transport a small number of ceramic substrates at a faster conveying speed. During the release of the ceramic substrate by the retractable adsorption airbag 48, several micro fans 82 can be started simultaneously. The micro fans 82 deliver air force to the top of the air duct 81. Since the conveyor belt 34 is a Teflon mesh conveyor belt with good air permeability and elasticity, the air force at the air duct 81 can directly act on the ceramic substrate that is in the release state above the conveyor belt 34, thereby providing an upward pushing and buffering effect for the ceramic substrate during the release process and preventing the ceramic substrate from directly colliding with the running conveyor belt 34. During the process of conveying ceramic substrates, the ceramic substrates will continue to move above the collection frame 92 under the driving force and inertial force of the conveyor belt 34 because the end of the collection frame 92 is in close contact with the surface of the conveyor belt 34. Several soft limiting rollers 95 and several guide strips 93 can limit the ceramic substrates, so that the ceramic substrates can smoothly enter the collection troughs 94 on the collection frame 92. The ceramic substrates collected later can push the ceramic substrates that have entered the collection troughs 94 first, so that multiple ceramic substrates can be neatly arranged in the collection troughs 94. After the ceramic substrates are collected, the fixing of the collecting frame 92 and the docking guide rail 91 can be released and the collecting frame 92 can be pulled to slide and separate the collecting frame 92 from the two docking guide rails 91, so as to disassemble the collecting frame 92 and facilitate subsequent processing of the collected ceramic substrates.
