[0054] The following is a description of the implementation of the present invention by specific embodiments. People familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0055] Combine the following Figure 1 and Figure 2 The automatic production line of thermosetting composite polystyrene insulation board provided by the present invention is introduced.

[0056] In a specific embodiment, the automatic production line of thermosetting composite polystyrene insulation board provided by the present invention includes a loading station 1, a drying station 2, a lowering station 3, a cutting station 4 and a packaging station 5; wherein the loading station 1 is located downstream of the workpiece processing equipment 6, and receives the discharge end of the workpiece processing equipment 6, the drying station 2 is arranged downstream of the loading station 1, and receives the discharge end of the loading station 1, the lowering station 3 is located downstream of the drying station 2, and receives the discharge end of the drying station 2, and the packaging station 5 is located downstream of the cutting station 4, and receives the discharge end of the cutting station 4; the workpieces are transferred between two adjacent stations through conveying equipment.

[0057] like Figure 2 As shown, the upper plate station includes a weighing device, a flap device 12 and a double workpiece separation device. The weighing device is used to collect the weight data of the target workpiece. The flap device 12 is provided with an image recognition device, and the image recognition device is used to obtain the image information of the target workpiece in the corresponding area of ​​the flap device 12; the double workpiece separation device has a lifting and separation function, which is used to separate the double plates for maintenance to prevent the workpieces from sticking. The lower plate station is located downstream of the drying station and takes over the discharge end of the drying station. The cutting station is located downstream of the lower plate station and takes over the discharge end of the lower plate station. The cutting station includes a fixed thickness sanding device and a fixed length cutting device. The fixed thickness sanding device is used for fixed thickness sanding with high precision requirements, and the fixed length cutting device is used to cut workpieces of different sizes; the packaging station is located downstream of the cutting station and takes over the discharge end of the cutting station.

[0058] In order to realize the automatic rejection of defective products and improve product quality, the automated production line also includes a control device, which is used to make a primary judgment based on the weight data collected by the weighing device to determine whether the target workpiece is a qualified product; the control device is also used to make a secondary judgment on the qualified products obtained by the primary judgment based on the image information of the target workpiece to determine whether the target workpiece is a qualified product. Furthermore, the control device is also used to control the working position of the forklift and the gripper according to the operating status of the two groups of unloading machines, so that by selectively loading the unloading machines, the two unloading machines can be used alternately to improve work efficiency.

[0059] Wherein, the pulling distance device 5 includes at least two belt conveyors arranged in sequence, and the running speed of each belt conveyor gradually increases along the moving direction of the workpiece. For example, the belt conveyor can be three groups, and the running speed of each belt conveyor can be 0-45 meters / min. For the convenience of description, from front to back, they are the first conveyor, the second conveyor and the third conveyor. In a specific use scenario, the running speed of the first conveyor is 10-40m / min, the running speed of the second conveyor is 40m / min, and the running speed of the third conveyor is 40m / min. When the workpiece reaches the preset position, the first end conveyor speeds up from low speed to high speed.

[0060] The workpiece processing equipment is an ultra-negative pressure production process line or a conventional insulation board production line, that is, the automated production line can be used in conjunction with an ultra-negative pressure production process line or a conventional insulation board production line.

[0061] The conveying equipment is a mobile gantry, conveyor belt or overhead crane. Taking the conveyor belt as an example, the traditional roller drive is replaced by a belt drive. Since the speed of the entire equipment needs to be increased from 9m / min to 40m / min, the speed difference is large. The roller transmission and the wet slurry on the workpiece will produce relative displacement, resulting in inaccurate speed increase, too long equipment production line, increased equipment failure rate, and high cost. At the same time, when the workpiece with wet material is transmitted on the roller, the wet material will be left on the roller to solidify. The radius of a single roller and the linear speed of different rollers are different, and the workpiece speed is inaccurate. The conveyor belt and the workpiece are in surface contact, which solves the problems of roller transmission.

[0062] During the working process, the workpiece is first formed on the processing equipment to obtain the insulation board in the form of the workpiece. After the workpiece is processed by the processing equipment, it is transported to the upper plate station. After the workpiece is turned over and unqualified parts are removed at the upper plate station, the qualified products are then transported to the drying station. The workpiece is dried at the drying station to remove moisture or other liquids to ensure the dryness and stability of the workpiece; the dried workpiece is continued to be transported to the lower plate station, which is located downstream of the drying station and takes over the discharge end of the drying station. After being unloaded and stacked, the workpiece is continued to be sent to the cutting station, and is cut to a fixed length as needed after thickness sanding at the cutting station, in preparation for the final packaging. The workpiece is transported to the packaging station for final packaging for easy transportation and storage. During the whole process, workpieces are transferred between two adjacent workstations through conveying equipment. These conveying equipment can be automated conveyor belts, robotic arms, elevators or other suitable mechanical devices, which ensure that the workpieces can be efficiently and accurately moved from one workstation to the next. Such a production line layout is designed to achieve continuous flow of workpieces, reduce manual intervention, and improve production efficiency and processing quality; by increasing the degree of automation in the insulation board production process, the breakage rate generated during manual operation can be reduced, thereby improving product quality, production efficiency and capacity.

[0063] In some embodiments, the loading station includes a loading conveyor belt 11, a weighing device, a pulling device, a flipping device 12, a double workpiece separation device and a sorting station 13; wherein, the feeding end of the loading conveyor belt 11 is connected to the discharging end of the workpiece processing equipment, the weighing device is arranged on the weighing station of the loading conveyor belt 11, the pulling device is arranged downstream of the weighing device, and the feeding end of the pulling device is connected to the discharging end of the loading conveyor belt 11; the flipping device 12 is arranged downstream of the pulling device, the feeding end of the flipping device 12 is connected to the discharging end of the pulling device, and the sorting station 13 is arranged downstream of the flipping device 12.

[0064] During the working process, the workpiece first enters the production line through the feeding end of the loading conveyor belt 11 after the workpiece is processed by the processing equipment. The loading conveyor belt 11 is responsible for smoothly conveying the workpiece from the processing equipment to other equipment on the board station. The workpiece moves to the weighing station on the loading conveyor belt 11, where a weighing device is provided (the weighing device can be a weighing sensor or an electronic scale). The weighing device is used to measure the weight of the workpiece to ensure that the workpiece meets the weight specification requirements. This step is crucial for quality control; the workpiece after weighing continues to move along the loading conveyor belt 11 to reach the pulling device to ensure that there is a sufficient distance between adjacent workpieces. After the workpiece comes out of the pulling device, it enters the flipping device 12, and the workpiece is turned over by the flipping device 12, and the back of the workpiece is facing up to facilitate subsequent defect inspection. The image recognition device provided at the flipping device 12 is used to detect defects on the workpiece. Workpieces with quality defects (such as bubbles on the surface, etc.) are moved to the sorting station 13 to be rejected as unqualified products, and qualified products enter the lower board area.

[0065] During the entire process, the workpiece undergoes a series of processing steps at the loading station, including conveying, weighing, rejection of defective products, flipping and sorting, to ensure that the workpiece meets the requirements of subsequent processing, improve production efficiency, ensure product quality, and realize the smooth operation of the automated production process.

[0066] In some embodiments, the flap device 12 includes a frame, a turning frame, a first clamping structure and a second clamping structure. The frame is installed beside the conveyor belt of the thermosetting composite polystyrene insulation board automatic production line, and the frame is the installation base of the flap device 12 on the overall production line equipment to avoid the flap device 12 being installed in the air and ensure the stability of the flap device 12. The turning frame is connected to the main power member by transmission, and rotates on a vertical plane relative to the frame under the drive of the main power member. The turning frame includes a first turning axis and a second turning axis arranged in parallel; the turning frame is the installation base of the first clamping structure and the second clamping structure. The turning frame can drive the synchronous rotation of the two clamping structures, and the structure of the turning frame should not interfere with the independent rotation of the two clamping structures. In other words, the two clamping structures can rotate synchronously with the turning frame, or they can rotate independently under the drive of the power member.

[0067] The first clamping structure is installed on the first flip axis and moves relative to the frame with the first flip axis, and the second clamping structure is installed on the second flip axis and moves relative to the frame with the second flip axis; the first clamping structure is transmission-connected to the first power member, and the second clamping structure is transmission-connected to the second power member; the first clamping structure rotates around the first flip axis under the drive of the first power member, and the second clamping structure rotates around the second flip axis under the drive of the second power member, so that the first clamping structure and the second clamping structure are closed or spread out on a vertical plane.

[0068] The initial position of the first clamping structure is the incoming end of the workpiece (i.e., the insulation board), that is, the insulation board processed by the upstream equipment and conveyed by the upstream conveyor belt first falls on the first clamping structure, and the initial position of the second clamping structure is the outgoing end of the workpiece. The downstream conveyor belt on one side of the second clamping structure conveys the turned insulation board to the downstream station. During the working process, after the workpiece is in place, the first clamping structure starts to rotate under the drive of the first power member; when the first clamping structure rotates to an appropriate angle, the first clamping structure rotates under the drive of the second power member, and clamps the workpiece by closing the first clamping structure and the second clamping structure together; after the workpiece is clamped between the two clamping structures, the flip frame drives the first clamping structure, the second clamping structure and the workpiece to rotate synchronously toward the initial position of the second clamping structure under the drive of the main power member. After rotating to an appropriate angle, the first clamping structure stops, and rotates in the opposite direction to the initial position and waits for the next action; the second clamping structure holds the workpiece and continues to rotate to the horizontal stop position toward the initial position of the second clamping structure, waiting for the workpiece to leave. In this way, the workpiece can be turned over smoothly by the plate turning device 12, so as to realize the turning operation of the insulation board, so as to cooperate with the subsequent sorting process to detect the quality of the back side of the insulation board.

[0069] In some embodiments, the first clamping structure includes a plurality of first cantilevers arranged at intervals, and one end of each of the first cantilevers is mounted on the first flip axis; the second clamping structure includes a plurality of second cantilevers arranged at intervals, and one end of each of the second cantilevers is mounted on the second flip axis, the first power member and the second power member are both servo motors, and the first flip axis and the second flip axis are concentric axes.

[0070] In some embodiments, the lower plate station includes a material discharging conveyor belt, a secondary distance-pulling device, a secondary sorting station and a packaging area; wherein the feeding end of the material discharging conveyor belt receives the discharging end of the drying station, the secondary distance-pulling device is arranged downstream of the material discharging conveyor belt, and the feeding end of the secondary distance-pulling device receives the discharging end of the material discharging conveyor belt; the secondary sorting station is arranged downstream of the secondary distance-pulling device, and the packaging area is arranged downstream of the secondary distance-pulling device and arranged in parallel with the secondary sorting station. It can be understood that the structural composition and process flow of the lower plate station are roughly the same as those of the upper plate station, and will not be described in detail here.

[0071] In addition to the above-mentioned thermosetting composite polystyrene insulation board automated production line, the present invention also provides a control method for the production line, such as Figure 3 As shown, the method comprises the following steps:

[0072] S310: Obtaining the current weight of the target workpiece at the weighing station of the loading station;

[0073] S320: Perform a judgment based on the weight data collected by the weighing device to determine whether the target workpiece is a qualified product; specifically, compare the current weight of the target workpiece with the pre-stored preset weight range. If the current mass is greater than the maximum value of the preset weight range, or less than the minimum value of the preset weight range, the target workpiece is determined to be an unqualified product, and the target workpiece is transported to the waste area; if the current mass is within the preset weight range, the target workpiece is determined to be a qualified product, and the target workpiece is transported to a downstream workstation.

[0074] S330: For qualified products obtained through a first judgment, a second judgment is performed on the qualified products obtained through a first judgment based on the image information of the target workpiece to determine whether the target workpiece is a qualified product. Specifically, the downstream workstation includes a flipping device 12, and image information of the target workpiece before and after the flipping device 12 flips the plate; the image information is compared with a pre-stored reference image. If the image information before and / or after flipping the plate does not match the reference image, the target workpiece is determined to be an unqualified product, and the target workpiece is transported to the waste area; if the image information before and / or after flipping the plate both match the reference image, the target workpiece is determined to be a qualified product, and the target workpiece is transported to the downstream workstation.

[0075] In a specific usage scenario, the specific control process of the loading station includes the following steps:

[0076] 1. Production line start-up:

[0077] The operator starts the production line on the control panel;

[0078] The belt conveyor of the rack loading machine receives the start signal and starts to operate.

[0079] 2. Workpiece conveying:

[0080] The processed workpiece is transported from the processing equipment outlet to the loading machine via a conveyor belt;

[0081] The loading conveyor belt 11 of the loading machine starts to operate and transports the workpiece to the weighing device.

[0082] 3. Weighing test:

[0083] The workpiece reaches the weighing device, which detects the weight of the workpiece;

[0084] If the weight of the workpiece meets the preset standard, the weighing device sends a signal to allow the workpiece to continue moving forward.

[0085] 4. Adjust the draw distance:

[0086] After the workpiece passes through the weighing device, it enters the pulling device;

[0087] The pull distance device adjusts the position of the workpiece according to the preset length standard.

[0088] 5. Flip operation:

[0089] The adjusted workpiece enters the flap device 12;

[0090] The flipping device turns the workpiece over, and the image recognition device performs defect detection on the workpiece before and after the flipping, so as to further eliminate unqualified workpieces.

[0091] 6. Sorting and removal from shelves:

[0092] After being turned over, the qualified workpieces enter the sorting station and are sorted according to their properties (such as size, weight, etc.). The sorted workpieces are transported to the downstream station.

[0093] During the process, if the operator finds an abnormal situation, he / she will immediately press the emergency stop button, which will trigger the safety mechanism and all belt conveyors and related equipment will stop running immediately. The operator will check and deal with the cause of the emergency stop. After troubleshooting, the operator will reset the equipment on the control panel. After the equipment performs a self-check and confirms that all safety conditions are met, the operator will restart the production line, and the racking machine and related equipment will resume normal operation and continue the work of conveying and racking the workpieces. During the entire control process, the operator needs to monitor the status of the production line to ensure the normal operation of all equipment. The control device should be equipped with necessary safety sensors and emergency stop devices to ensure the safety of the operator and equipment.

[0094] The specific control logic of the weighing detection part involves ensuring that the weight of the workpiece during the conveying process meets the predetermined standard, and the workpiece that does not meet the weight requirement is promptly rejected as a defective product. Figure 4 As shown, in a specific usage scenario, the specific control strategy for the weighing device in the plate loading station is that when the workpiece reaches the weighing area, the weighing sensor is triggered to start measuring the weight of the workpiece; the weighing sensor converts the measured weight value into an electrical signal and sends it to the control device. After receiving the weight signal, the control device compares it with the preset weight range; if the weight of the workpiece is within the preset qualified range, the control device will send a signal to the belt so that the belt drives the workpiece to continue to move forward; if the weight of the workpiece exceeds the preset range (exceeds the maximum value of the preset weight range or is lower than the minimum value of the preset weight range), the control device will determine that the workpiece is unqualified. For unqualified workpieces, the control device will trigger the corresponding actuator (such as a cylinder, a push rod, etc.) to move the workpiece from the main conveyor belt to the waste or defective conveyor belt; for qualified workpieces, the control device keeps the main conveyor belt running, allowing the workpiece to continue to move to the next station. Regardless of whether the workpiece is qualified or not, the control device can record the weighing data for subsequent quality traceability and statistical analysis. If the weighing sensor or control device detects an abnormality (such as sensor failure, signal interference, etc.), it will trigger an alarm and stop the conveyor belt, waiting for the operator to intervene. After the operator troubleshoots the problem, the system can be reset manually, or in some cases, the system can automatically reset and continue to run; the control logic of the weighing detection part needs to be continuously monitored to ensure that the weight detection of the workpiece is always accurate. This control logic ensures that the weight detection of the workpiece on the production line is both accurate and efficient, and that defective products can be handled in a timely manner to ensure product quality. In actual applications, the control logic of weighing detection can be adjusted according to specific production needs and equipment characteristics.

[0095] The control strategy of the distance device is to ensure that the workpieces maintain the correct spacing during the conveying process, which is very important for subsequent processing and handling. In a specific usage scenario, the specific control strategy of the distance device can be that when the workpiece passes through the weighing device, it enters the detection area of ​​the distance device, and the detection sensor (such as a photoelectric sensor) detects whether the front edge of the workpiece has arrived; once the front edge of the workpiece is detected, the distance device starts to measure the distance between the workpieces, and the control device sets the standard distance between the workpieces according to production requirements; the control device compares the actual measured distance with the preset standard distance; if the actual distance is less than the preset distance, the control device adjusts the speed of the three groups of belt conveyors to increase the speed difference between the speed of the downstream belt conveyor and the upstream belt conveyor, thereby increasing the distance between the workpieces; if the actual distance is greater than the preset distance, the control device adjusts the speed of the three groups of belt conveyors to reduce the speed difference between the speed of the downstream belt conveyor and the upstream belt conveyor, thereby reducing the distance between the workpieces. This control strategy ensures that the spacing control of the workpieces on the production line is both accurate and reliable, which helps to improve the efficiency and quality of subsequent processing. In practical applications, the control strategy for distance adjustment can be adjusted according to specific production needs and equipment characteristics.

[0096] In a specific usage scenario, such as Figure 5 As shown, the working process of the flipping device includes the following steps:

[0097] 1. Receiving signal: The turning machine receives a signal from the control device, which indicates that a workpiece is about to reach the turning area.

[0098] 2. Workpiece arrival: The workpiece arrives at the entrance of the turning machine through the conveyor belt, triggering the sensor at the entrance.

[0099] 3. Stop conveying: After the sensor detects the workpiece, it sends a signal to the control device, which instructs the conveyor belt to stop to ensure accurate positioning of the workpiece.

[0100] 4. Positioning confirmation: The positioning sensor on the flipping machine confirms that the workpiece has reached the correct flipping position.

[0101] 5. Execute flipping: Once the workpiece is positioned, the control device sends a command to the actuator of the flipping machine (such as a cylinder or hydraulic system) to execute the flipping action, and the flipping device turns the workpiece over.

[0102] 6. Flipping completed: After the flipping action is completed, the position sensor or limit switch detects that the workpiece has been flipped to the predetermined position.

[0103] 7. Conveying restart: After the control device receives the signal that the flipping is completed, it restarts the conveyor belt and transports the flipped workpiece to the next station.

[0104] During the entire flipping process, if any abnormality is detected (such as the workpiece is not positioned correctly, the flipping mechanism is faulty, etc.), the control device will trigger an alarm and stop the relevant operation. The operator intervenes to check and solve the problem, and then restarts the flip machine manually or automatically. If the emergency stop button of the flip machine is pressed, or the control device detects an emergency, all flip machines and related conveying equipment will stop immediately. After the problem is solved, the operator can reset the system, and the flip machine and conveyor belt return to the initial state and wait for the next operation instruction.

[0105] In a specific usage scenario, such as Figure 6 As shown, the working process of the upper computer in the upper station includes the following steps:

[0106] 1. System power-on and initialization: After the system is powered on, the racking machine is initialized and all components (such as conveyor belts, sensors, control units, etc.) enter standby mode;

[0107] 2. Check linkage function: All belt conveyors have linkage function to ensure that all related equipment can work together before the loading machine starts working;

[0108] 3. Emergency stop button check: Check the status of the emergency stop button. If the emergency stop button is pressed, the equipment will stop immediately until the problem is solved and the alarm is cleared;

[0109] 4. The plate arrives at the loading station: the plate arrives at the entrance of the loading station after the previous processing and transportation;

[0110] 5. Stop conveying to position the plate: In order to ensure the correct positioning of the plate, the conveyor belt stops temporarily when the plate reaches the loading station;

[0111] 6. Plate positioning: The edge or specific mark of the plate is detected by the sensor to ensure that the plate is correctly positioned on the racking machine;

[0112] 7. Execution of the racking action: After positioning is completed, the racking machine performs the racking action and places the plate on the predetermined shelf or storage location;

[0113] 8. Confirm that the loading is completed: After the loading is completed, confirm that the plate has been placed correctly through the limit switch or sensor;

[0114] 9. Restart the conveyor belt: After confirming that the plates are correctly loaded, the conveyor belt restarts and continues to transport the subsequent plates to the loading station.

[0115] In some embodiments, the method further comprises:

[0116] The working positions of the forklift and the gripper are controlled according to the operating status of the two sets of unloading machines.

[0117] Specifically, Figure 7-10As shown, after the system is started, the forklift and the gripper are in the initial position, waiting for the operation signal of the unloading machine; through the sensor or state monitoring system, the working status of the two groups of unloading machines is detected in real time, including whether they are running and whether there are plates unloading. The linkage control logic is that when the first group of unloading machines starts working, the system will send signals to the forklift and the gripper according to its operating status; similarly, the working status of the second group of unloading machines will also be monitored and send corresponding control signals; when controlling the working position of the forklift and the gripper, during the operation of the first group of unloading machines, if the first group of unloading machines starts unloading, the forklift moves to the designated position of the first group of unloading machines and prepares to receive the plates; the gripper adjusts to the appropriate gripping position according to the position and size of the plates of the first group of unloading machines. During the operation of the second group of unloading machines, if the second group of unloading machines starts unloading, the forklift moves to the designated position of the second group of unloading machines and prepares to receive the plates, and the gripper adjusts to the appropriate gripping position according to the position and size of the plates of the second group of unloading machines. When two groups of unloading machines are working at the same time, if the two groups of unloading machines are working at the same time, the forklift needs to decide which unloading machine position to move to first according to the preset priority or scheduling algorithm; the gripper also needs to decide which unloading machine's plate to grab first according to the priority or scheduling algorithm. The working position control of the forklift and the gripper needs to work in coordination with the linkage function of the belt conveyor to ensure the smoothness of the entire unloading and packaging process. The linkage control logic refers to the coordination of multiple devices or machines through the control system in the automated production line to ensure the continuity and efficiency of the entire production process. Real-time monitoring of the working status of the two groups of unloading machines, including whether they are running, whether there are plates unloading, etc., monitors the position of the forklift and the gripper to ensure that they can respond to the state changes of the unloading machines. The linkage control decision is that when the first group of unloading machines completes the unloading of plates, the control system decides whether the forklift and the gripper need to intervene according to the preset logic; similarly, the status of the second group of unloading machines will also trigger the corresponding linkage control decision. If two groups of unloading machines complete unloading at almost the same time, the control system needs to determine the movement path of the forklift according to the preset priority or scheduling algorithm; the forklift moves to the designated unloading machine position according to the instructions of the control system, ready to receive the plate. When positioning the gripper, the gripper automatically adjusts to the appropriate gripping position based on the plate position information provided by the unloading machine; the position adjustment of the gripper needs to consider the size and weight of the plate to ensure safe and accurate gripping. After the forklift arrives at the designated position, the gripper performs the gripping action and takes the plate from the unloading machine, and the forklift then transports the plate to the next station or storage area.

[0118] During the working process, the workpiece is first formed on the processing equipment to obtain an insulation board in the form of a workpiece. After the workpiece is processed by the processing equipment, it is transported to the upper plate station. After the workpiece is turned over and unqualified parts are removed at the upper plate station, the qualified products are then transported to the drying station. The workpiece is dried at the drying station to remove moisture or other liquids to ensure the dryness and stability of the workpiece; the dried workpiece is continued to be transported to the lower plate station. The lower plate station is located downstream of the drying station and takes over the discharge end of the drying station to prepare for the final packaging. The workpiece is transported to the packaging station for final packaging to facilitate transportation and storage. During the whole process, workpieces are transferred between two adjacent workstations through conveying equipment. These conveying equipment can be automated conveyor belts, robotic arms, lifts or other suitable mechanical devices, which ensure that workpieces can be efficiently and accurately moved from one workstation to the next. Such a production line layout is designed to achieve continuous flow of workpieces, reduce manual intervention, and improve production efficiency and processing quality; by increasing the degree of automation in the production process of insulation boards, the breakage rate generated during manual operation can be reduced, thereby improving product quality, production efficiency and capacity. At the same time, during the working process, the production line uses dual quality inspections of weight detection and image recognition to promptly and efficiently handle unqualified products and ensure product quality.

It should be understood that the above are only specific implementation methods of the present invention and are not intended to limit the scope of protection of the present invention.
