Description

Technical Field

[0001] This application relates to the field of parts picking equipment, and in particular to a device for automatic sorting of valve plates. Background Technology

[0002] In the compressor manufacturing industry, key components such as intake and exhaust valve plates are typically small in size and extremely thin. Because these products are often stacked haphazardly after stamping and grinding, and different models of valve plates are extremely similar in appearance, mixing of materials frequently occurs.

[0003] Currently, valve plate post-processing mainly relies on manual labor, including type confirmation, defect inspection, manual differentiation of front and back sides, and stacking and packaging. However, due to the extreme thinness and sharp edges of the valve plates, manual operation is not only physically demanding but also poses a risk of finger cuts. Furthermore, prolonged manual work can lead to visual fatigue, making it difficult to guarantee a 100% detection rate for minor appearance defects and mixed-type products.

[0004] Traditional automated sorting equipment typically uses a rejection mode, which involves placing the valve plates to be sorted on a conveyor belt and then rejecting the defective products by air blowing or mechanical levers. However, for thin valve plates with a thickness of only 0.15mm, air blowing can easily cause the valve plates to lose control of their posture or even scatter, while mechanical rejection can easily cause physical damage to the thin plates, such as bending or scratches. Summary of the Invention

[0005] In order to reduce the adverse effects of the sorting process on valve plates, this application provides a device for automatic sorting of valve plates.

[0006] The device for automatic sorting of valve plates provided in this application adopts the following technical solution:

[0007] An apparatus for automatic sorting of valve discs includes a first conveying assembly for conveying valve discs to be sorted;

[0008] The second conveying assembly is used to convey the sorted qualified valve plates. The conveying surface of the second conveying assembly is provided with a first dropping area and a second dropping area that both extend along its conveying direction and are arranged side by side.

[0009] A feeding assembly, located at the starting end of the first conveying assembly, is used to place the valve plates to be sorted onto the first conveying assembly.

[0010] A visual inspection component is used to acquire image information of the valve plate on the first conveying component, and to determine the qualification and orientation of the valve plate based on the image information.

[0011] A picking assembly is used to pick up valve plates that are determined to be qualified on the first conveying assembly and transfer the qualified valve plates to the second conveying assembly; the picking assembly includes at least two sets of picking components, each picking component including a robotic arm and a first suction nozzle disposed at the movable end of the robotic arm; at least one set of the picking components is used to place qualified valve plates facing forward in the first discharge area, and at least another set of the picking components is used to place qualified valve plates facing backward in the second discharge area;

[0012] A collection box, located at the end of the second conveying assembly, is used to receive qualified valve plates falling from the first and second drop areas.

[0013] A waste bin, located at the end of the first conveying assembly, is used to receive defective valve plates that are not picked up by the picking assembly and are output with the first conveying assembly.

[0014] By adopting the above technical solution, this device uses a visual inspection component to identify qualified and unqualified valve plates. For valve plates that do not meet the requirements, such as those with quality defects or other types of defects, the picking component does not perform any action; instead, it allows the valve plate to move naturally to the end of the first conveyor component and fall into the waste box. This avoids the active striking or pushing action of traditional rejection mechanisms, thus avoiding the risk of valve plate breakage due to jamming or impact. Simultaneously, for qualified valve plates, the picking component's transfer function does not flip the valve plates. Instead, by changing the lateral landing point of the valve plates on the second conveyor component, valve plates with the front facing up are uniformly placed in the first dropping area, and valve plates with the back facing up are uniformly placed in the second dropping area. This achieves the separation of valve plates with different orientations. Then, with the help of the collection box, neatly arranged front and back valve plates can be obtained separately. Subsequently, the sorted valve plates can be directly packaged and boxed. Therefore, this application can ensure the stable operation of the valve plate sorting process, and transfer qualified valve plates during the sorting process. During the transfer process, the front and back valve plates are classified and sorted at the same time. Compared with traditional sorting equipment, there is no need to set up a flipping mechanism, which helps to simplify the structure and improve the reliability of the device.

[0015] Two independent picking units perform the sorting and picking actions for the front and back valve plates respectively, which helps to improve the sorting cycle time of the system. When the incoming materials are dense, a single robotic arm may not be able to process the front and back valve plates at the same time. The dual-set design balances the load and ensures that qualified products are not missed when the conveyor is in high-speed mode, thus improving the overall sorting efficiency.

[0016] Optionally, the first conveying component and the second conveying component have opposite conveying directions, so that the starting end of the first conveying component and the ending end of the second conveying component are on the same side.

[0017] By adopting the above technical solution, the starting end of the first conveying component is the feeding end, and the conveying end of the second conveying component is the discharging end. By converging the feeding and discharging ends on the same side of the device, operators can complete raw material replenishment and finished product collection at the same workstation, shortening the operation path and improving the efficiency of single-person equipment management. Simultaneously, the waste box is located at the other end of the device, increasing the distance between waste and qualified products, reducing the risk of waste accidentally falling into the finished product due to the waste box being too close to the collection box. Furthermore, while feeding, the operator can scan the quality of the returned finished product in real time. If a problem is found in the vision system, such as transferring non-compliant valve plates to the end of the second conveying component, or damage to the valve plates during the material handling process, the operator can promptly detect and stop the machine at the feeding end. If the first and second conveying components convey in the same direction, the finished product will accumulate at the tail end, making it difficult for the operator to inspect in time, potentially leading to a large outflow of defective products.

[0018] Optionally, the feeding assembly includes a hopper and a transfer component. The hopper is used to store stacked valve plates to be sorted. The transfer component includes a first linear sliding member, a second linear sliding member, and a second suction nozzle. The sliding direction of the movable end of the second linear sliding member is perpendicular to the sliding direction of the movable end of the first linear sliding member. The second linear sliding member is connected to the movable end of the first linear sliding member. The second suction nozzle is connected to the movable end of the second linear sliding member and is used to adsorb the valve plates to be sorted placed on the first conveying assembly.

[0019] By adopting the above technical solution, the second suction nozzle is driven by the linear sliding component to perform the picking and placing action. Compared with vibratory feeder feeding, this method can more gently separate the stacked thin-walled valve plates one by one and lay them flat on the first conveying component. This effectively reduces friction and collision between valve plates and lowers the scratch rate during the feeding process, making it particularly suitable for products with high surface finish requirements. At the feeding end, operators can simply arrange the valve plates before placing them into the hopper. During arrangement, it is only necessary to ensure that the valve plates to be tested are stacked neatly. The subsequent sorting process is then achieved through a sorting device. Alternatively, the front-end feeding process can also be achieved through other material handling equipment, as long as the valve plates to be tested are arranged into a neat stack.

[0020] Optionally, the collection box is provided with a lifting component, which includes a first power telescopic member and a support plate located at the movable end of the first power telescopic member. The support plate is located in the collection box, and the top wall of the support plate is used to place a valve plate. The first power telescopic member is used to drive the support plate to slide along the height direction of the collection box.

[0021] By adopting the above technical solution, the first power telescopic component drives the bearing plate to rise and fall, enabling the system to adjust the bearing height in real time according to the number of stacked valve plates, always maintaining a small drop between the drop point and the top valve plate. By receiving the valve plates with a small height difference, it can prevent the thin valve plates from tipping or deflecting during the fall from the bearing plate due to excessive height difference, and can also reduce the scratches caused between adjacent valve plates due to excessive drop height.

[0022] Optionally, the bottom end of the support plate is provided with a guide rod, which slides along the height direction of the collection box and passes through the bottom wall of the collection box. The end of the guide rod away from the support plate is detachably connected to the movable end of the first power telescopic member.

[0023] By adopting the above technical solution, once the collection box contains the required amount of valve plates, the connection between the bottom end of the guide rod and the movable end of the first power telescopic component can be detached, and the collection box containing the valve plates can then be transferred to the subsequent packaging process; therefore, the aforementioned detachable connection facilitates the transfer of the collection box. Furthermore, when the collection box is full of valve plates, the support plate is located on the bottom side inside the collection box. At this time, the bottom end of the guide rod protrudes from the bottom wall of the collection box. After moving the collection box to the subsequent packaging station, during the process of placing the collection box on the platform, the bottom end of the guide rod will first abut against the platform surface. Then, as the collection box is lowered, since the guide rod and support plate cannot continue to move downwards, the support plate will move upwards relative to the collection box. When the bottom wall of the collection box abuts against the external platform surface, the support plate moves to the top of the collection box, thus facilitating the removal of the valve plates from the collection box.

[0024] Optionally, a guide plate is provided between the end of the second conveying component and the carrier plate, and the guide plate is inclined downward from the end of the second conveying component to the carrier plate.

[0025] By adopting the above technical solution, the inclined guide plate provides a smooth sliding transition path for the valve plate, avoiding the loss of attitude caused by the direct transition from horizontal conveying to vertical falling, and ensuring that the valve plate can fall into the collection box smoothly and orderly.

[0026] Optionally, the collection box is provided with a limiting component, which includes a fixed component and a movable component. Multiple movable components are provided, and the fixed component and the multiple movable components are arranged together around the outside of the support plate. The movable components are slidably connected to the inside of the collection box. The sliding direction of the multiple movable components is arranged in a ring-shaped interval to drive the multiple movable components to simultaneously press against the periphery of the valve plate. A first elastic element is connected between the movable components and the collection box. The collection box is also provided with a driving component for driving the multiple movable components to overcome the elastic force of the first elastic element and slide inward.

[0027] By adopting the above technical solution, during the process of receiving valve pieces one by one on the support plate, stacking misalignment is inevitable. Multiple movable parts, under the action of the driving component, can overcome the elastic force of the first elastic element and slide inward as a whole, thus cooperating with the stationary fixed part to simultaneously squeeze and close the valve pieces from their periphery. This periodic squeezing and closing action can adjust the valve pieces that have just fallen and may be misaligned, forcibly arranging the scattered valve pieces into a neat stack. When the driving component releases its force, under the action of the first elastic element, the movable parts automatically reset and open, reserving space for the next valve piece to fall in and avoiding interference. In traditional methods, all valve plates are dropped and then sized up at once. Because the valve plates are thin, a large number can be accumulated in the collection box. During sizing, the lower valve plates experience greater pressure, making them prone to scratches and affecting finished product quality. In this new method, sizing is performed sequentially after a certain number of valve plates have dropped. Each sizing primarily targets the upper valve plates, which experience less pressure. Therefore, the sizing process is less likely to scratch the valve plates, helping to ensure finished product quality.

[0028] Optionally, the driving component includes a second power telescopic member, a connecting rope, and a slider. The fixed member and each of the movable members are provided with a connecting ring. The connecting rope passes through the connecting ring on each of the movable members. Both ends of the connecting rope pass through the connecting ring on the fixed member. Both ends of the connecting rope are connected to the slider. The slider is connected to the movable end of the second power telescopic member. The second power telescopic member is used to drive the slider and the end of the connecting rope to move, so that the multiple movable members slide inward.

[0029] By adopting the above technical solution, when the second power telescopic component pulls the slider, the slider simultaneously tightens both ends of the connecting rope. The connecting ropes threaded in each connecting ring are gathered, causing all moving parts with connecting ropes to converge towards the center simultaneously. This structure requires only one drive source to achieve simultaneous clamping of the entire material from multiple directions, avoiding the structural complexity and excessive size problems caused by arranging multiple drive cylinders around a small collection box. Furthermore, the use of connecting rope transmission ensures that the force on each moving part is relatively balanced, achieving centered clamping. Since the connecting rope is located below the collection box, it will not interfere with the valve plate during the gathering process, helping to ensure the smooth progress of the gathering process.

[0030] Optionally, the movable end of the second power telescopic member is detachably connected to the slider. A locking component is provided between the slider and the collection box. The locking component includes a rod and a second elastic member. The rod is slidably inserted into the slider. The second elastic member is connected between the rod and the slider. The collection box has a slot for the rod to be inserted along the sliding path of the slider. There are multiple slots, which are arranged at intervals. The second elastic member is used to drive the rod to tend to insert into the slot.

[0031] By adopting the above technical solution, the collection box filled with finished products can be removed from the equipment as an independent turnover unit. When the valve plates are full, the control drive component pulls the connecting rope to a tensioned state. At this time, the slider moves to a specific locking position. Under the action of the second elastic element, the end of the insert automatically springs into the corresponding slot, thereby locking the slider's position and maintaining the tension of the connecting rope to ensure the neat stacking of the internal valve plates. Even if the connection with the first and second power telescopic components is disconnected, the multiple moving parts still maintain a tight clamping state on the valve plate stack. This ensures that the valve plates inside the collection box will not scatter due to vibration or tilting during the handling process, greatly facilitating material transfer between production lines. Because multiple slots are provided, valve plates of different sizes can be accommodated, which helps improve the applicability of the device.

[0032] Optionally, the slider includes a first connecting part and a second connecting part that are slidably connected. The first connecting part is used to connect to the two ends of the connecting rope, and the second connecting part is used to connect to the movable end of the second power telescopic member. A third elastic member is connected between the first connecting part and the second connecting part, and the third elastic member is used to drive the first connecting part to abut against the second connecting part.

[0033] By adopting the above technical solution, flexible protection for the fragile valve plate is achieved. When multiple moving parts press inward against the valve plate, if the resistance increases, the third elastic element will absorb the excess stroke, effectively preventing excessive compression of the moving parts due to excessive power source stroke, thereby avoiding damage to the thin-walled valve plate, and also preventing the connecting rope from breaking due to excessive tension.

[0034] In addition, the elastic structure of the slider provides crucial tolerance compensation, ensuring the reliability of self-locking. To achieve mechanical self-locking in conjunction with the aforementioned locking components, the slider needs to move precisely to the location of the slot. Even slight differences in the stacked dimensions of the valve plates within the collection box can cause the rope to tighten prematurely. In this design, even if the first connecting part stops moving prematurely due to rope tension, the second connecting part can still continue sliding under the drive of the power source, overcoming the elastic force of the third elastic element, until it accurately reaches the slot position and triggers the insert rod mounted thereon for locking, thereby improving the operational stability and fault tolerance of the device.

[0035] In summary, this application includes the following beneficial technical effects:

[0036] 1. By combining visual inspection with picking components, defective products fall naturally along the conveyor line, while qualified products are placed in different drop areas according to their front and back sides. This avoids the risk of valve plate damage caused by traditional mechanical knocking and forced flipping, while realizing automatic classification and non-destructive sorting of valve plates with front and back sides.

[0037] 2. By adopting a dynamically lifting support plate and an inclined guide structure, the valve plates can always be received with a small drop. Then, through the connecting rope and the drive of the moving parts, the loading action of thin valve plates can be realized during the loading process, thus effectively solving the problem of thin-walled valve plates being easy to scatter and stack disorderly during high-speed collection.

[0038] 3. The collection box is detachably connected to the first power telescopic component and the second power telescopic component respectively, and the collection box is provided with a locking component for locking the position of the slider, so that the collection box can still maintain the clamping state of the internal valve plate through the connecting rope after it is separated from the drive source, turning the collection box into a turnover unit that can be transported independently, and avoiding the collapse and scattering of the finished valve plate during the transportation process.

Detailed Implementation

[0050] The following combination Figures 1-10 This application will be described in further detail.

[0051] Example 1: This application discloses a device for automatic sorting of valve plates. (Refer to...) Figure 1The device for automatic sorting of valve plates includes a frame 14, on which a first conveying assembly 1 for conveying valve plates 19 to be sorted and a second conveying assembly 2 for conveying sorted valve plates 19 are mounted. Both the first conveying assembly 1 and the second conveying assembly 2 are belt conveyors. The conveying directions of the first conveying assembly 1 and the second conveying assembly 2 are arranged in parallel, thus facilitating the transfer of valve plates 19.

[0052] The first conveying assembly 1 has a feeding assembly 3 at its starting end, which includes a hopper 31 and a transfer component 32. The hopper 31 is a vertically upward cylindrical structure, and the shape of its hollow inner cavity matches the shape of the valve pieces 19 to be sorted. The interior of the hopper 31 is used to store multiple valve pieces 19 stacked vertically. The bottom of the hopper 31 is equipped with a lifting cylinder to maintain a constant height of the picking surface. The transfer component 32 is used to transfer the valve pieces 19 placed in the hopper 31, and two sets of transfer components 32 are provided. The frame 14 has a mounting frame 15 on the side near the starting end of the first conveying assembly 1, and two mounting frames 15 are provided, each corresponding to one of the two sets of transfer components 32. Each set of transfer components 32 is connected to the corresponding mounting frame 15. Correspondingly, there are also two hoppers 31, each corresponding to one of the two sets of transfer components 32.

[0053] Reference Figure 1 and Figure 2 The following description uses the first set of transfer components 32 as an example. The first set of transfer components 32 includes a first linear sliding member 321, a second linear sliding member 322, and a second suction nozzle. Both the first linear sliding member 321 and the second linear sliding member 322 are linear motors. The first linear sliding member 321 is horizontally mounted above the first conveying assembly 1, and the sliding direction of the movable end of the first linear sliding member 321 is parallel to the conveying direction of the first conveying assembly 1. The fixed end of the first linear sliding member 321 is fixedly connected to the mounting bracket 15, and the movable end of the first linear sliding member 321 is connected to the fixed end of the second linear sliding member 322; the movable end of the second linear sliding member 322 is vertically slidable. The movable end of the second linear sliding member 322 is elongated, and the second suction nozzle is fixedly connected to the bottom end of the second linear sliding member 322 (the second suction nozzle is not shown in the figure). The second suction nozzle is a sheet-like structure with multiple suction holes. The second suction nozzle is connected to a vacuum negative pressure system, so it can pick up a valve plate 19 located at the top of the hopper 31 through the second suction nozzle.

[0054] During operation, the second linear sliding member 322 drives the second suction nozzle to descend to the top of the hopper 31. After the second suction nozzle picks up a single valve plate 19, it rises. The first linear sliding member 321 drives the second suction nozzle to move horizontally above the belt surface of the first conveying assembly 1. The second linear sliding member 322 drives the second suction nozzle to descend again, causing the second suction nozzle to release the vacuum and lay the valve plate 19 flat on the belt surface of the moving first conveying assembly 1, thereby realizing the automatic feeding of the thin-walled valve plate 19.

[0055] Both sets of transfer components 32 are located at the starting end of the first conveying assembly 1, and the two sets of transfer components 32 are arranged vertically; that is, the first linear sliding member 321 in the first set of transfer components 32 is arranged along the conveying direction of the first conveying assembly 1, and the first linear sliding member 321 in the second set of transfer components 32 is arranged along the width direction of the belt surface in the first conveying assembly 1. The two sets of transfer components 32 are arranged at intervals and staggered from each other, so interference is unlikely to occur during installation. The two sets of transfer components 32 work simultaneously, which can place two rows of valve plates 19 to be sorted on the belt surface of the first conveying assembly 1, which helps to improve sorting efficiency.

[0056] The hopper 31 is equipped with a photoelectric switch for detecting the remaining material level. The photoelectric switch is installed at a preset height on the side wall of the hopper 31, with its sensing end facing the feeding channel inside the hopper 31. During continuous operation, the photoelectric switch can scan and monitor the stack height of the valve plates 19 inside the hopper 31 in real time. When the stack height of the valve plates 19 is detected to be lower than the preset detection position of the photoelectric switch, it indicates that the remaining quantity is insufficient. At this time, the photoelectric switch immediately generates a material shortage monitoring signal and feeds it back to the control system. The system then triggers an audible and visual alarm to prompt the operator to replenish the material in time, thereby realizing automated real-time monitoring of the remaining quantity of valve plates 19.

[0057] Reference Figure 1 A vision inspection component 4, including an industrial CCD camera, is installed on the frame 14 near the starting end of the first conveyor assembly 1. The CCD camera is located directly above the first conveyor assembly 1, with its lens facing the belt surface of the first conveyor assembly 1, for continuously acquiring high-definition image information of the valve plates 19 passing through this area. The vision system controller receives the images, determines whether the valve plates 19 have defects such as missing corners or mixed shapes according to a preset algorithm, identifies whether the qualified valve plates 19 are currently facing up or down, and calculates their position coordinates, providing a precise position data basis for subsequent sorting operations.

[0058] A picking assembly 5 is provided on the frame 14 in the area behind the vision inspection assembly 4. The picking assembly 5 includes two sets of picking components 51 arranged at intervals along the conveying direction of the first conveying assembly 1. Each set of picking components 51 includes a spider-hand robotic arm 511, which is located above the first conveying assembly 1. The movable end of the spider-hand robotic arm 511 faces downward and is provided with a first suction nozzle 512. The first suction nozzle 512 is connected to a vacuum negative pressure system, so that the valve plate 19 located on the top surface of the first conveying assembly 1 can be picked up through the first suction nozzle 512. One spider-arm robotic arm 511 is used to pick up the valve plate 19 facing upwards, and the other spider-arm robotic arm 511 is used to pick up the valve plate 19 facing downwards. The two spider-arm robotic arms 511 perform different actions, thus making full use of both robotic arms 511 and avoiding one robotic arm 511 operating frequently while the other robotic arm 511 is idle. This helps to ensure work efficiency and reduce the possibility of missed detections.

[0059] The vision inspection component 4 and the two sets of picking components 51 are all electrically connected to the main control system. During operation, when the vision inspection component 4 determines that a qualified valve plate 19 has entered the gripping area, the main control system controls the picking components 51 to move. The picking components 51 track and adsorb the valve plate 19 on the first conveyor component 1 according to the coordinates, and quickly transfer the adsorbed valve plate 19 to the top belt surface of the parallel second conveyor component 2. If the vision determines that the valve plate 19 is unqualified, such as being out of size, having a defective appearance, or being a mixed type valve plate 19, the picking components 51 will not perform any gripping action, allowing the unqualified valve plate 19 to continue moving with the first conveyor component 1. Therefore, this sorting method prevents easily jammed or irregularly shaped waste materials from passing through the mechanical gripper, avoiding the risk of gripping failure or scratches, improving the stability of the device operation, and ensuring the sorting effect.

[0060] The top surface of the second conveying assembly 2 has a first dropping area 21 and a second dropping area 22 in the width direction, with the first dropping area 21 located on the inner side and the second dropping area 22 located on the outer side. The first dropping area 21 is only used to place qualified valve pieces 19 facing upwards, and the second dropping area 22 is only used to place qualified valve pieces 19 facing downwards. One set of picking components 51 is only used to pick up qualified valve pieces 19 facing upwards, thus this picking component 51 can transfer qualified valve pieces 19 facing upwards from the first conveying assembly 1 to the first dropping area 21 on the second conveying assembly 2; the other set of picking components 51 is only used to pick up qualified valve pieces 19 facing downwards, thus this picking component 51 can transfer qualified valve pieces 19 facing downwards from the first conveying assembly 1 to the second dropping area 22 on the second conveying assembly 2. Thus, after picking and transferring, two rows of finished product stacks are formed on the second conveying assembly 2, moving side by side and facing the same direction. Without the need for a flipping mechanism, the valve plates 19 can be sorted and organized during the picking process, which is convenient for subsequent packaging.

[0061] It should be noted that the conveying direction of the first conveying component 1 is opposite to that of the second conveying component 2. For example, if the first conveying component 1 is set to convey to the left, the feeding component 3 is located at the right end of the first conveying component 1, i.e., the starting end of the first conveying component 1; the second conveying component 2 conveys to the right, so the output end is also located on the right side. A collection box 6 is provided at the end of the second conveying component 2. The collection box 6 is placed on top of the support frame (not shown in the figure). The collection box 6 is located below the top surface of the second conveying component 2, with its opening facing upwards. Therefore, the two rows of valve plates 19 on the surface of the second conveying component 2 can fall into the collection box 6, forming two stacks of valve plates 19 in the collection box 6. One stack of valve plates 19 is uniformly face up, and the other stack of valve plates 19 is uniformly face down. When the required number of valve plates 19 are collected in the collection box 6, the collection box 6 can be removed, and the valve plates 19 with uniform orientation can be packaged in subsequent processes.

[0062] At the left end of the first conveying component 1, i.e. the output end, a waste box 7 is also provided. The waste box 7 is located below the top belt surface of the first conveying component 1, and the opening of the waste box 7 faces upward. Therefore, after sorting, the valve plates 19 placed on the top belt surface of the first conveying component 1 are all valve plates 19 that do not meet the requirements. Then, these valve plates 19 can be conveyed to the waste box 7 as the first conveying component 1 is running, and then manually judged whether to scrap them.

[0063] With the reverse arrangement of the first conveying component 1 and the second conveying component 2 in opposite directions, the operator only needs to stand on the right side of the device to both add material to the hopper 31 of the feeding component 3 and receive finished products from the collection box 6 from the right side. The waste box 7, located on the left end, is farther from the collection box 6 on the right end, greatly reducing the probability of waste material mixing with the finished product and helping to ensure sorting quality.

[0064] The frame 14 is further protected by an outer casing around the picking assembly 5 and the vision inspection assembly 4, thus extending their service life. The frame 14 also features a display system that shows two main components: a diagram of the valve plate 19 to be sorted, and real-time updates on the equipment's operating status and parameters for operator monitoring. This results in a simple and intuitive user interface, allowing operators to quickly master the operation with minimal training, reducing operational difficulty and training costs.

[0065] The implementation principle of Example 1 is as follows: The first linear sliding member 321 and the second linear sliding member 322 cooperate to remove the valve plates 19 from the hopper 31 one by one and place them flat on the top belt surface of the first conveying assembly 1. The CCD camera identifies the information of the valve plates 19; if it is a qualified front valve plate 19, the first picking component 51 picks it up and transfers it to the first dropping area 21 on the second conveying assembly 2; if it is a qualified back valve plate 19, the second picking component 51 picks it up and transfers it to the second dropping area 22; if it is a valve plate 19 that does not meet the requirements, it falls into the waste box 7 at the end with the first conveying assembly 1. Finally, the sorted front and back good products are output from the conveying end of the second conveying assembly 2.

[0066] Example 2: Refer to Figure 3 , Figure 4 and Figure 5The difference between this embodiment and Embodiment 1 is that, in this embodiment, the collection box 6 is equipped with a lifting component 8 inside. The lifting component 8 includes a first power telescopic component 81 and a support plate 82. The first power telescopic component 81 is a servo electric cylinder. In other embodiments, the first power telescopic component 81 can also be a cylinder or an electric push rod. The first power telescopic component 81 is located below the collection box 6, and the movable end of the first power telescopic component 81 is vertically upward. The support plate 82 is located inside the collection box 6 and is horizontally arranged. A guide rod 821 is fixedly connected to the bottom end of the support plate 82. The guide rod 821 slides vertically through the bottom of the collection box 6, and the bottom end of the guide rod 821 protrudes from the bottom wall of the collection box 6 and is detachably connected to the movable end of the first power telescopic component 81. Therefore, the first power telescopic component 81 can drive the carrier plate 82 to slide up and down along the height direction in the collection box 6. Whenever a certain amount of valve plates 19 are loaded into the collection box 6, the carrier plate 82 can move down a certain distance, thereby ensuring that the distance between the top of the belt surface of the second conveying component 2 and the topmost valve plate 19 in the collection box 6 is not too large, avoiding the valve plate 19 from falling too far and causing it to overturn or deflect during the fall, thus ensuring the collection effect of the picked valve plates 19.

[0067] Since the collection box 6 can simultaneously store valve plates 19 facing upwards and valve plates 19 facing downwards, two sets of lifting components 8 are provided, spaced apart. One set of lifting components 8 carries the valve plates 19 facing upwards and drives this portion of valve plates 19 to move downwards intermittently to ensure stable material dropping. The other set of lifting components 8 carries the valve plates 19 facing downwards and drives this portion of valve plates 19 to move downwards intermittently to ensure stable material dropping. Because the two sets of lifting components 8 are controlled independently, even if there is a significant difference between the number of valve plates 19 facing upwards and the number of valve plates 19 facing downwards among the selected valve plates 19, resulting in a significant difference in the number of valve plates 19 in the two rows on the belt surface of the second conveying component 2, the two sets of lifting components 8 can control the timing of descent according to the actual material dropping situation during the subsequent material dropping process, so as to ensure that neither the valve plates facing upwards nor the valve plates facing downwards will fall too high.

[0068] Furthermore, a downwardly inclined guide plate 9 is provided between the output end of the second conveying component 2 and the support plate 82 in the collection box 6. The end of the guide plate 9 near the conveying end of the second conveying component 2 is the higher end. Therefore, the guide plate 9 can guide the valve plate 19 to smoothly transition from horizontal conveying to sliding towards the top wall of the support plate 82. In conjunction with the descent of the support plate 82, a small drop height difference can always be maintained.

[0069] Reference Figure 6The collection box 6 is provided with limiting components 10, which are provided in two sets, corresponding to the support plates 82 in the two sets of lifting components 8 respectively. The limiting component 10 includes a fixed member 101 installed on one side of the bottom wall of the collection box 6 and three movable members 102 distributed in the other three positions. The sliding directions of the three movable members 102 are arranged in a ring, with the sliding direction of the two movable members 102 adjacent to the fixed member 101 along the length direction of the collection box 6, and the sliding direction of the movable members 102 opposite to the fixed member 101 along the width direction of the collection box 6. The fixed member 101 and the three movable members 102 are arranged in a ring around the support plate 82, forming a storage space that matches the shape of the valve plate 19. In this embodiment, the valve plate 19 is a rectangular sheet structure, so the fixed member 101 and the three movable members 102 can form a rectangular frame structure.

[0070] In this embodiment, both the fixing member 101 and the movable member 102 are limiting plates arranged along the height direction of the collection box 6. Therefore, the three movable members 102 are close to each other, which can push the valve plate 19 to move, thereby achieving the effect of organizing the valve plate 19 and ensuring that the valve plate 19 is neatly stacked. In other embodiments, the fixing member 101 and the movable member 102 may also include multiple parallel and spaced support rods fixedly connected together. The support rods are arranged along the height direction of the collection box 6, which can also achieve the effect of organizing the valve plate 19.

[0071] Reference Figure 6 , Figure 7 and Figure 8 Each movable component 102 has a vertically connected connecting post 1021 fixedly connected to its bottom end. The bottom wall of the collection box 6 has three guide grooves 62, each corresponding to one of the three connecting posts 1021. Each connecting post 1021 slides through its corresponding guide groove 62, allowing for a sliding fit between the movable component 102 and the bottom wall of the collection box 6. A first elastic element 103, which is a spring, is connected between the end of each connecting post 1021 extending through the bottom wall of the collection box 6 and the bottom wall of the collection box 6. Under normal conditions, the first elastic element 103 is at its original length. At this time, adjacent movable components 102 and the fixed component 101 are spaced apart, creating a large opening in the storage space formed by the fixed component 101 and the movable component 102, facilitating the valve plate 19 to fall into. Because they are spaced apart, the three movable components 102 have room to move inwards.

[0072] The collection box 6 is also equipped with a driving component 11 for driving the three movable parts 102 to slide inward synchronously. The driving component 11 includes a connecting rope 112, a slider 113, and a second power telescopic component 111. A connecting ring 12 is fixedly connected between the connecting post 1021 at the bottom of each movable part 102 and the bottom of the fixed part 101. All four connecting rings 12 are located on the outer side of the bottom wall of the collection box 6. The connecting rope 112 passes through the connecting rings 12 on the three connecting posts 1021, and both ends of the connecting rope 112 pass through the connecting rings 12 at the bottom of the fixed part 101 and are fixedly connected to the slider 113. The second power telescopic component 111 is a servo electric cylinder. In other embodiments, the second power telescopic component 111 can also be a pneumatic cylinder or an electric push rod. The second power telescopic component 111 is fixedly installed on the support frame. The second power telescopic component 111 is located below the collection box 6 and is horizontally arranged. The movable end of the second power telescopic component 111 is detachably connected to the slider 113.

[0073] During operation, the movable end of the second power telescopic member 111 retracts, pulling the slider 113 to move, thereby tightening the connecting rope 112. Under this force, the connecting rope 112 contracts inward, overcoming the elastic force of the first elastic member 103. Simultaneously, it pulls the three movable members 102 towards the center, causing the valve plates 19 scattered on the support plate 82 to be squeezed by the peripheral movable members 102 and ultimately pressed against one side of the fixed member 101, thus positioning the valve plates 19. When the movable end of the second power telescopic member 111 extends, the tension on the connecting rope 112 weakens. At this time, under the action of the first elastic member 103, the movable members 102 loosen and slide away from the valve plates 19, returning to their initial state for the next pushing and positioning.

[0074] Reference Figure 9 The slider 113 includes a first connecting part 1131 and a second connecting part 1132. The first connecting part 1131 is an inner cylinder, and the second connecting part 1132 is an outer cylinder that is slidably sleeved on the outer wall of the inner cylinder. A third elastic element 1133, which is a spring, is provided inside the first connecting part 1131. The two ends of the third elastic element 1133 are respectively connected to the inner walls of the first connecting part 1131 and the second connecting part 1132. The third elastic element 1133 is in a stretched state, so that the open end of the first connecting part 1131 abuts against the inner wall of the second connecting part 1132. The end of the first connecting part 1131 is fixedly connected to the two ends of the connecting rope 112, and the end of the second connecting part 1132 is detachably connected to the movable end of the second power telescopic member 111. Therefore, when the second power telescopic member 111 drives the slider 113 to move, it can play a buffering role, avoiding the rigid setting from causing the connecting rope 112 to be over-tensioned, which would have an adverse effect on the valve plate 19.

[0075] Reference Figure 9and Figure 10 In addition, the movable end of the first power telescopic member 81 and the bottom of the guide rod 821, and the movable end of the second power telescopic member 111 and the slider 113 are all detachably connected. Therefore, when loading is required, the movable end of the first power telescopic member 81 and the bottom of the support plate 82, and the movable end of the second power telescopic member 111 and the slider 113 can be fixed to ensure the loading effect. After the loading process is completed, when the valve plate 19 needs to be transferred, the connection between the movable end of the first power telescopic member 81 and the bottom of the support plate 82, and the movable end of the second power telescopic member 111 and the slider 113 can be disconnected. Then, the collection box 6 can be removed to easily transfer the stacked valve plates 19 after sorting. The collection box 6 can be reused. When the collection box 6 containing the valve plates 19 is removed for reuse, the empty collection box 6 can be reloaded to continue the sorting process.

[0076] Reference Figure 10 The detachable structures between the movable end of the first power telescopic member 81 and the bottom of the guide rod 821, and between the movable end of the second power telescopic member 111 and the slider 113 are the same. The detachable structure between the movable end of the first power telescopic member 81 and the bottom of the guide rod 821 will be described as an example. This detachable structure includes a sleeve 16, a locking pin 17, and a spring 18. The sleeve 16 is fixedly connected to the movable end of the first power telescopic member 81. A groove is provided at the top of the sleeve 16 for the bottom end of the guide rod 821 to insert into, and a locking hole 8211 is provided at the bottom of the guide rod 821 for the locking pin 17 to insert into. The locking pin 17 slides horizontally through the sleeve 16, and the spring 18 is connected between the locking pin 17 and the outer wall of the sleeve 16. After the collection box 6 is placed stably, the bottom end of the guide rod 821 is inserted into the sleeve 16. At this time, the locking pin 17 is simultaneously inserted into both the sleeve 16 and the locking hole 8211, thus restricting the relative movement between the bottom end of the guide rod 821 and the movable end of the first power telescopic member 81, completing the temporary connection between the two. When it is necessary to disassemble the connection later, simply pull the locking pin 17 out of the locking hole 8211, then move the collection box 6 upwards, causing the guide rod 821 to disengage from the sleeve 16.

[0077] Reference Figure 9A locking component 13 is also provided between the slider 113 and the collection box 6. The locking component 13 includes a rod 131 and a second elastic element 132. The second connecting part 1132 of the slider 113 has a hole 1132a, in which the rod 131 slides. The second elastic element 132 is a spring, which connects the rod 131 and the slider 113. Correspondingly, a slot 61 is provided on the bottom wall of the collection box 6. Multiple slots 61 are provided and spaced apart along the width direction of the collection box 6. The slots 61 are located on the sliding path of the slider 113, and the end of the rod 131 can be inserted into the slot 61. The second elastic element 132 always applies a force to the rod 131, pressing it towards the slot 61.

[0078] Once the required number of valve pieces 19 are loaded into the collection box 6, the second power telescopic member 111 will continue to drive the slider 113 to move a short distance, causing the insertion rod 131 on the slider 113 to move to an alignment with the slot 61. At this time, the second elastic member 132 can drive the end of the insertion rod 131 to slide into the slot 61, thereby restricting the sliding of the slider 113 relative to the collection box 6, forming a mechanical self-locking mechanism, and keeping the connecting rope 112 in a taut state. After the connection between the second power telescopic member 111 and the slider 113 is subsequently disconnected, the connecting rope 112 can still maintain a taut state, thereby ensuring that the valve pieces 19 are firmly clamped inside the collection box 6. At this point, the entire collection box 6 can be removed and transported as a separate turnover unit without worrying about the thousands of valve pieces 19 neatly arranged inside collapsing and becoming disordered. After the collection box 6 containing the valve plate 19 is transferred to the packaging area, the end of the insert rod 131 can be pulled out of the slot 61, and then the slider 113 can be slid away from the slot 61 and then the slider 113 can be released. At this time, the first elastic member 103 can apply an outward force to the movable member 102, which makes it easier to remove the valve plate 19 inside the collection box 6.

[0079] Since the collection box 6 is provided with multiple slots 61, the insert rod 131 can be inserted into different slots 61 for valve plates 19 of different sizes, thereby improving the applicability of the device.

[0080] Reference Figure 6It should be noted that when the collection box 6 is full of valve plates 19, the support plate 82 is placed at the bottom of the collection box 6, and the bottom end of the guide rod 821 extends a considerable distance from the bottom wall of the collection box 6. When the collection box 6 is moved to the packaging area, it is placed on the platform. First, the bottom end of the guide rod 821 abuts against the surface of the platform. Then, as the collection box 6 moves downward, the guide rod 821 and the support plate 82 remain stationary, so the support plate 82 slides upward relative to the collection box 6. When the mounting frame 63 at the bottom of the collection box 6 is placed on the platform surface, the support plate 82 is located on the side closer to the top of the collection box 6. At this time, the valve plates 19 loaded on the support plate 82 are also located in the area close to the top of the collection box 6, thus facilitating the quick removal of the valve plates 19 from the collection box 6. The mounting frame 63 is fixedly installed on the outer wall of the bottom of the collection box 6. The mounting frame 63 is located at the edge of the collection box 6, and the bottom end of the mounting frame 63 is located below the bottom end of the connecting ring 12. Therefore, when the bottom wall of the mounting frame 63 abuts against the external platform, the collection box 6 can be supported by the mounting frame 63, avoiding unstable placement that could damage the structure of the connecting ring 12 and the connecting column 1021.

[0081] In this embodiment, the collection box 6 contains two stacks of valve plates 19, with one stack of valve plates 19 facing upwards and the other stack facing downwards. In other embodiments, the belt surface of the second conveying assembly 2 can also simultaneously convey four rows of valve plates 19, with two rows of valve plates 19 placed in the first dropping area 21 and the other two rows of valve plates 19 placed in the second dropping area 22. Then, the four rows of valve plates 19 can fall into the same collection box 6. This can be achieved by setting two sets of limiting components 10 on each bearing plate 82 and then setting four second power telescopic components 111 on one side of the collection box 6, thereby further improving the sorting efficiency.

[0082] The implementation principle of Example 2 is as follows: During the collection of qualified valve plates 19, when the second conveying component 2 conveys the valve plates 19 that have been visually identified as qualified to the end, the valve plates 19 will smoothly slide along the inclined guide plate 9 onto the support plate 82 inside the collection box 6. During the collection process, the control system controls the first power telescopic component 81 to move according to the number or thickness of the collected valve plates 19, driving the support plate 82 to gradually descend. This process ensures that the uppermost stacked surface of the support plate 82 always maintains a small, constant height difference with the end of the guide plate 9, effectively preventing the thin valve plates 19 from tipping over due to excessive falling height.

[0083] To address the potential for misalignment or uneven stacking of valve pieces 19 after they fall, the device performs a periodic alignment process. The specific procedure is as follows: After a certain number of valve pieces 19 are stacked on the support plate 82, the movable end of the second power telescopic member 111 retracts, causing the slider 113 to move. The slider 113 then pulls the end of the connecting rope 112. Since the connecting rope 112 is threaded through the connecting rings 12 of each movable member 102, as the slider 113 pulls, the connecting rope 112 retracts inward, overcoming the elastic force of the first elastic member 103 and pulling the movable members 102 distributed in different positions to slide synchronously towards the center of the collection box 6. At this time, multiple movable members 102 simultaneously press inward from the circumferential direction, pushing the valve pieces 19 that have just fallen on the support plate 82 to a neat and aligned state. After the alignment process is completed, the movable end of the second power telescopic member 111 extends, and the first elastic member 103 drives the movable member 102 to spring outward, reserving space for the subsequent valve pieces 19 to fall.

[0084] When the picking component 51 transfers the valve plate 19 on the first conveying component 1 to the second conveying component 2, the valve plate 19 on the top surface of the second conveying component 2 is divided into multiple parts, each part consisting of multiple valve plates 19 spaced apart or stacked on top of each other, and the multiple parts are arranged at intervals. After all the valve plates 19 in one part fall into the collection box 6, the above-mentioned material sorting action is performed. After the material sorting action is completed, the next part of valve plates 19 continues to fall. Therefore, the material sorting process does not affect the sorting process and helps to ensure work efficiency.

[0085] When the number of valve plates 19 in the collection box 6 reaches the preset full load value and needs to be transferred, the control system controls the second power telescopic member 111 to pull the slider 113 to the state where the insertion rod 131 is aligned with the slot 61. At this time, the second elastic member 132 drives the end of the insertion rod 131 to insert into the slot 61, which can fix the slider 113 on the collection box 6, thereby keeping the connecting rope 112 in a taut state, so that all the moving parts 102 tightly abut against the stacked valve plates 19 inside.

[0086] After self-locking is completed, even if the external power is cut off or the driving force is removed, the slider 113 cannot lock back, and the connecting rope 112 can continuously maintain the tension on the moving part 102, thereby maintaining the clamping state of the internally stacked valve plates 19. Subsequently, the operator disconnects the detachable connection between the first power telescopic part 81 and the bearing plate 82, and the second power telescopic part 111 and the slider 113, so that the entire collection box 6 can be removed. During the transportation process, since the internal valve plates 19 are always under pressure and clamping, the stack of valve plates 19 will not collapse or scatter, regardless of bumps or tilting, realizing a closed-loop operation from automatic collection of scattered thin plates to modular overall transportation.

[0087] After moving the collection box 6 to the packaging area, it can be placed on the platform. During the lowering process, the guide rod 821 will first abut against the surface of the platform, allowing the support plate 82 to move upward relative to the collection box 6. Once the collection box 6 is on the platform, the support plate 82 and the valve plate 19 placed on the support plate 82 move to the top of the collection box 6. Then, the end of the insertion rod 131 is pulled out of the slot 61. At this time, the first elastic member 103 can apply an outward force to the movable member 102, facilitating the removal of the valve plate 19 inside the collection box 6.

[0088] The above are optional embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
