Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of fastener heat treatment conveying, and particularly to an intelligent fastener heat treatment conveying device. BACKGROUND

[0002] In the field of fastener heat treatment production, a stacking device is often used in cooperation with a three-dimensional conveying structure to realize the storage, carrying and process transfer of fasteners. The stacking device is mainly used to grasp and carry fasteners to be heat treated or fasteners that have been heat treated at the three-dimensional conveying frame, and to complete the taking and placing of fasteners between different workstations and layer heights.

[0003] The existing stacking device and supporting conveying structure for fastener heat treatment have many technical defects. The three-dimensional conveying frame corresponding to the traditional stacking device needs to reserve a special lane for the stacking machine to pass through, which greatly occupies the space of the heat treatment plant, limits the number of fastener carrying positions per unit area, and reduces the space utilization. During the heat treatment of fasteners, workers need to frequently pass through the narrow conveying frame lane to check, arrange and assist the loading and unloading of the parts carrying fasteners. The narrow space not only easily causes collision accidents between personnel and equipment, but also exposes workers to the high-temperature environment of heat treatment for a long time, increasing the risk of high-temperature burns.

[0004] At the same time, the conveying frame supporting the traditional stacking device adopts a "last-in, first-out" storage and conveying mode, which is not suitable for the processing of high-strength fasteners sensitive to heat treatment aging and process stability, as the heat treatment process requires high consistency and sequence, and manual errors can easily cause the heat treatment sequence of fasteners to be disordered, and some fasteners may be affected by the heat treatment precision due to the long residence time.

[0015] As preferred, the intelligent scheduling system is in communication connection with the high-temperature-resistant RFID reader-writer, the pressure sensor arranged on the bearing assembly, the high-temperature-resistant distance detection module arranged at the end of the partition plate, and the control systems of the transfer mechanism and the driving mechanism.

[0016] In the above technical solution, the present invention provides an intelligent fastener heat treatment conveying device, which has the following beneficial effects: On the circular slide rails of each partition, the support plates can be moved sequentially to the end station of the three-dimensional conveyor frame via chain drive mechanism. Workers do not need to enter the conveyor frame aisle; they only need to stand at the end station to inspect and load / unload the fastener boxes on the support plates that have moved to their front. This avoids workers having to walk through narrow aisles between the conveyor frames and keeps them away from the high-temperature heat treatment area, reducing the risk of collisions and high-temperature burns. The support plates move to the station in a preset sequence, reducing the time workers spend searching for fasteners and simultaneously improving the efficiency of inspection and loading / unloading. At the same time, there is no need to reserve aisle space, which greatly reduces the floor space occupied by the three-dimensional conveyor frame and improves the equipment layout density and space utilization rate in the heat treatment plant.

[0017] The support plate moves cyclically in a fixed direction on the circular slide rail of the partition, with the end of the conveyor frame as the only storage and retrieval station. Fasteners to be heat-treated are placed on the empty support plate from the end station by the transfer mechanism, and move away from the station with the chain, entering the conveyor frame to participate in the subsequent heat treatment process. Fasteners that have completed heat treatment move cyclically with the support plate to the end station, and are picked up by the transfer mechanism and transferred to the next process. This realizes the first-in, first-out rule of "fasteners placed last arrive at the station last, and fasteners placed first are processed first", avoiding the wrong order of heat treatment process caused by human error, ensuring the consistency of fastener heat treatment process, and is especially suitable for high-strength fastener processing scenarios that are sensitive to heat treatment aging and process precision.

[0018] The transfer mechanism does not need to enter the conveyor aisle to perform horizontal movement; it only needs to move up and down within a fixed vertical channel at the end of the conveyor, and complete the fastener placement and removal operations through the extension and retraction of the pick-and-place forks. The horizontal movement of the bearing plate is entirely completed independently by the drive mechanism. The transfer mechanism eliminates the time-consuming three-dimensional coordination of "horizontal movement + vertical lifting + fork extension" in traditional heat treatment conveying equipment, and only needs to focus on the vertical lifting action. The time for a single pick-and-place transfer is significantly shortened, improving the overall conveying efficiency. At the same time, the transfer mechanism does not need to travel at high speed in narrow aisles, effectively reducing the probability of wear and collision of mechanical parts in high-temperature environments, reducing equipment maintenance frequency and costs, and extending the service life of the device.

[0019] Each layer of the partition's support plate can move independently along the circular slide rail to the end station. The transfer mechanism moves back and forth between end stations of different heights via vertical lifting, realizing the exchange and transfer of fasteners across layers. When the distribution of fasteners on a certain layer of the conveyor rack is uneven and local overload occurs, the transfer mechanism can remove some fasteners from the end station of the overloaded layer and transport them to the end station of the vacant layer for storage. The support plate adjusts its position synchronously to adapt to the load change. By dynamically adjusting the distribution of fasteners, the bottleneck of heat treatment efficiency caused by the "local congestion and local idleness" of traditional conveyor racks is avoided, ensuring the smooth operation of the conveyor channels on each layer and improving the overall heat treatment conveying capacity and operational stability of the unit.

[0023] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0024] Please see Figures 1-8 An intelligent fastener heat treatment conveying device includes a ceiling track 1 fixedly installed on the top of a factory building, a transfer mechanism 2 set at the bottom of the ceiling track 1, and a three-dimensional conveyor frame 3 fixedly installed on the ground. The three-dimensional conveyor frame 3 includes: partitions 4, which are horizontally welded to the surface of the three-dimensional conveyor frame 3; a bearing component 7, which is evenly arranged on the surface of the partitions 4 and slides on the surface of the partitions 4 using electromagnetic levitation technology, thereby reducing the friction between the bearing component 7 and the partitions 4, and is used to carry fasteners to be heat treated or already heat treated; and a drive mechanism 6, which is set on the surface of the three-dimensional conveyor frame 3. Each partition 4 corresponds to a set of drive mechanisms 6, and the drive mechanisms 6 are used to drive the bearing components 7 to move on the partitions 4 to achieve orderly conveying of fasteners.

[0025] During assembly, the overhead rail 1 is fixed to the top of the heat treatment plant, and the three-dimensional conveyor frame 3 is fixed to the ground. The fasteners to be heat treated are placed on the bearing component 7. The drive mechanism 6 drives the bearing component 7 to slide along the partition 4 to realize the conveying of fasteners between various heat treatment stations. The transfer mechanism 2, in conjunction with the overhead rail 1, can realize the transfer of fasteners between different three-dimensional conveyor frames 3 or different layers, adapting to the layout of automated heat treatment production lines.

[0026] Furthermore, the support assembly 7 includes a support plate 73 and a fastener placement box 71. The fastener placement box 71 is detachably disposed on the surface of the support plate 73. The surface of the fastener placement box 71 is evenly provided with partition grooves for classifying and placing fasteners of different specifications. The inner wall of the partition groove is provided with a high-temperature resistant protective pad.

[0027] According to the specifications of the fasteners to be heat-treated, fasteners of different models are placed into the partition slots of the placement box. The high-temperature resistant protective pad can prevent the fasteners from being worn or stuck to the placement box under the high temperature of heat treatment. The detachable design of the placement box facilitates subsequent cleaning, maintenance and replacement of fasteners of different specifications, and improves the versatility of the device.

[0028] Furthermore, the partition 4 is composed of two parallel support plates and two symmetrical semi-circular ring plates. The two parallel support plates are set on both sides of the three-dimensional conveyor frame 3, and the two semi-circular ring plates are set at both ends of the three-dimensional conveyor frame 3. The parallel support plates and semi-circular ring plates are connected end to end and integrally formed to form a ring structure. Multiple partitions 4 are spaced apart along the vertical direction. Each layer of partition 4 is an independent ring structure, which is suitable for the cyclic conveying requirements of fasteners in the heat treatment process.

[0029] The ring-shaped partition 4 enables the cyclic conveying of fasteners without the need for an additional return mechanism, improving conveying efficiency and adapting to the "feed-heat-cool-discharge" cyclic process of heat treatment; the multi-layer independent partition 4 layout enables the simultaneous conveying of fasteners in different batches and different processing states, saving factory floor space and meeting the needs of large-volume fastener heat treatment.

[0030] Furthermore, a high-temperature resistant magnetic levitation circular slide rail 5 is fixedly installed on the surface of the partition 4. The bottom of the support plate 73 has a groove that matches the size of the high-temperature resistant magnetic levitation circular slide rail 5. An electromagnet 53 is fixedly installed on the top wall of the groove. The electromagnet 53 cooperates with the magnetic components of the high-temperature resistant magnetic levitation circular slide rail 5 to levitate the support plate 73 through electromagnetic repulsion. Both sides of the high-temperature resistant magnetic levitation circular slide rail 5 are provided with embedding grooves 51. Guide wheels 52 are rotatably connected to the grooves of the support plate 73 near the two side ports. The embedding grooves 51 cooperate with the guide wheels 52 to limit the lateral displacement of the support plate 73 during the sliding process and ensure the stability of the fasteners during the heat treatment and conveying process. The surface of the support plate 73 has a limiting hole 74 that precisely matches the position and size of the support foot 72 of the placement box. When the placement box is placed, the support foot 72 is inserted into the limiting hole 74 to achieve quick positioning of the placement box and the support plate 73. This further prevents the placement box from shaking or shifting during the movement and turning of the support plate 73 and avoids the fasteners from falling or colliding.

[0031] During heat treatment, the electromagnet 53 is energized to generate electromagnetic repulsion, causing the bearing plate 73 to suspend above the slide rail, which greatly reduces friction during the conveying process and reduces wear and energy consumption in high-temperature environments. The guide wheel 52 is embedded in the groove 51 on both sides of the slide rail, which can prevent the bearing plate 73 from shifting or shaking during high-speed conveying or turning, avoid damage to fasteners due to displacement and collision, and ensure the stability of conveying under high-temperature conditions.

[0032] Furthermore, the drive mechanism 6 includes a high-temperature resistant third motor 66, two sprockets 63, and a high-temperature resistant chain 61. The high-temperature resistant chain 61 is sleeved on the surface of the two sprockets 63. The high-temperature resistant third motor 66 is fixedly installed on the surface of the three-dimensional conveyor frame 3, and the high-temperature resistant third motor 66 of each drive mechanism 6 is located at one end of the corresponding partition 4. A connecting shaft 62 is fixedly passed through the center of each of the two sprockets 63. The output shaft port of the high-temperature resistant third motor 66 is fixedly connected to the connecting shaft 62. A tension adjustment mechanism is provided at a position of the three-dimensional conveyor frame 3 away from the high-temperature resistant third motor 66 to adjust the tension of the high-temperature resistant chain 61 to adapt to the transmission requirements under heat treatment environment.

[0033] The high-temperature third motor drives the connecting shaft 62 and sprocket 63 to rotate, which drives the high-temperature resistant chain 61 to circulate, thereby pulling the bearing component 7 to move along the annular slide rail, meeting the power transmission requirements under the high-temperature environment of heat treatment; the tension adjustment mechanism can adjust the tightness according to the chain wear and high-temperature deformation, avoiding the transmission failure caused by the chain loosening, and ensuring the long-term stable operation of the drive mechanism 6.

[0034] Furthermore, the tension adjustment mechanism includes a slider 64, which is slidably connected inside the three-dimensional conveyor frame 3. The connecting shaft 62 is rotatably connected to the surface of the slider 64. A high-temperature resistant electric telescopic rod 65 is fixedly installed inside the three-dimensional conveyor frame 3. The output end of the high-temperature resistant electric telescopic rod 65 is fixedly connected to the slider 64 to realize the automatic adjustment of the tension of the high-temperature resistant chain 61.

[0035] During operation, the chain tension can be monitored in real time by the control system. When the chain becomes loose due to high temperature deformation or wear, the high temperature resistant electric telescopic rod 65 drives the slider 64 to move, which drives the sprocket 63 to move synchronously, automatically adjusting the chain tension. No manual shutdown is required for adjustment, improving the continuity of the heat treatment production line and adapting to the needs of unmanned operation.

[0036] Furthermore, two high-temperature resistant connecting rods 76 are fixedly installed on the side wall of the bearing plate 73. The high-temperature resistant chain 61 is arranged in a closed loop around the annular structure of the partition plate 4. The two high-temperature resistant connecting rods 76 of each bearing plate 73 are hinged to the high-temperature resistant chain 61. As the high-temperature resistant chain 61 moves in a cycle, it drives the bearing plate 73 to slide along the partition plate 4. When the high-temperature resistant connecting rods 76 rotate with the high-temperature resistant chain 61, they drive the bearing plate 73 to smoothly transition between the parallel support plate and the semi-circular annular plate, ensuring the continuity of fastener transportation.

[0037] Furthermore, the connecting rods hinge the bearing plate 73 to the chain, transforming the chain's cyclical motion into the smooth sliding of the bearing plate 73. The design of the two connecting rods enhances connection stability. When the chain drives the bearing plate 73 through the semi-circular ring plate turning section, the connecting rods can flexibly adjust their angles with the chain's rotation, achieving a smooth transition of the bearing plate 73 without jamming, preventing fasteners from falling off or shifting due to bumps, and ensuring continuous and stable conveying throughout the entire process.

[0038] Furthermore, the transfer mechanism 2 includes a walking assembly 21, which is slidably connected to the overhead rail 1 via a pulley system. A vertical rod 24 is rotatably connected to the bottom of the walking assembly 21, and a screw 25 is rotatably connected inside the vertical rod 24. A high-temperature resistant second motor 23 for driving the screw 25 to rotate is fixedly installed inside the vertical rod 24 near the top. A long groove is provided on the side wall of the vertical rod 24, and a sliding plate 26 is slidably connected to the surface of the vertical rod 24 through the long groove. The screw 25 is threaded through the sliding plate 26, and a pick-and-place fork 27 is slidably connected to the surface of the sliding plate 26. A high-temperature resistant cylinder 28 for driving the pick-and-place fork 27 to move is fixedly installed on the side wall of the sliding plate 26. A high-temperature resistant first motor 22 for driving the vertical rod 24 to rotate is fixedly installed inside the walking assembly 21, realizing the transfer of fasteners between different layers and the connection of heat treatment processes.

[0039] During transfer, the walking component 21 moves along the overhead rail 1 to above the target bearing component 7. The first motor drives the vertical rod 24 to rotate and adjust the orientation of the pick-and-place fork 27. The second motor drives the screw 25 to rotate and drive the slide plate 26 to rise and fall, adapting to the height of different layers of partitions 4. The high-temperature resistant cylinder 28 pushes the pick-and-place fork 27 to extend and retract, inserting it into the bottom of the bearing plate 73 to pick up and place fasteners, completing the transfer between different layers and different conveyor frames, and connecting the nodes of each heat treatment process.

[0040] Furthermore, the side wall of the bearing plate 73 is provided with an information storage module 75, and the front end of the slide plate 26 is provided with an information reading module 8. The information storage module 75 is a high-temperature resistant RFID tag that stores information such as fastener specifications, heat treatment status, and conveying path. The information reading module 8 is a high-temperature resistant RFID reader / writer that communicates with the control system to identify the bearing component 7 and fastener-related information to ensure conveying accuracy.

[0041] After the fasteners are loaded onto the carrier component 7, information such as the fastener specifications, preset heat treatment process, and target work station is written into the RFID tag. When the transfer mechanism 2 moves to the pick-up and drop-off position, the RFID reader reads the tag information, confirms the identity of the fasteners and the processing requirements, and feeds back to the control system to achieve accurate transfer. At the same time, the heat treatment status information can be updated to facilitate full traceability and avoid mixing and mis-order processing.

[0042] Furthermore, it also includes an intelligent scheduling system, which is communicatively connected to a high-temperature RFID reader, a pressure sensor mounted on the bearing component 7, a high-temperature distance detection module 9 mounted at the end of the partition 4, and the control systems of the transfer mechanism 2 and the drive mechanism 6. The intelligent scheduling system has a built-in artificial intelligence algorithm module for: Real-time acquisition of RFID tag information of each load-bearing component 7, load data of pressure sensors, obstacle signals of high-temperature distance detection module 9, and progress information of fastener heat treatment process; The dynamic generation of the running path of the transfer mechanism 2 and the power distribution strategy of the drive mechanism 6 enables the rotation angle of the walking component 21 and the vertical rod 24 of the transfer mechanism 2 and the moving distance of the pick-and-place fork 27 to be synchronized with the position of the bearing component 7 and the rhythm of the heat treatment process. The speed of the high-temperature resistant third motor 66 and the stroke of the high-temperature resistant electric telescopic rod 65 of the control drive mechanism 6 are optimized. The moving speed of the bearing component 7 is adjusted based on load data, heat treatment temperature environment and process requirements to achieve energy-saving, efficient and precise fastener heat treatment conveying.

[0043] As the core control unit of the device, the intelligent scheduling system integrates data from various sensors and readers in real time, dynamically plans the conveying path through algorithms to avoid collisions with the load-bearing components, and adjusts the conveying speed according to the rhythm of the heat treatment process. For example, it slows down before the heating station to facilitate accurate feeding and speeds up after the cooling station to improve efficiency. Based on load data, it optimizes the motor speed and chain tension, taking into account both energy saving and stability, and realizes intelligent management and control of the entire process of fastener heat treatment conveying.

[0044] Working principle: During assembly, the overhead rail 1 is fixed to the top of the heat treatment plant, and the three-dimensional conveyor frame 3 is fixed to the ground. The power supply of each mechanism and the intelligent scheduling system are then connected. Fasteners to be heat treated are placed on the bearing component 7. The drive mechanism 6 drives the bearing component 7 to slide along the partition 4, realizing the conveying of fasteners between various heat treatment stations. The transfer mechanism 2, in conjunction with the overhead rail 1, can realize the transfer of fasteners between different three-dimensional conveyor frames 3 or between different layers, adapting to the layout of automated heat treatment production lines.

[0045] According to the specifications of the fasteners to be heat-treated, different types of fasteners are placed into the partition slots of the fastener placement box 71. The high-temperature resistant protective pads on the inner walls of the partition slots can prevent the fasteners from wearing or sticking to the placement box under high-temperature conditions. The placement box adopts a detachable design, which can be removed for cleaning and maintenance after use. It can also be replaced with a placement box that is compatible with different specifications of fasteners, improving the versatility of the device.

[0046] After the device is started, the high-temperature resistant magnetic levitation annular slide rail 5 on the surface of the partition 4 is energized. The electromagnet 53 at the bottom of the support plate 73 generates electromagnetic repulsion, causing the support plate 73 to levitate above the slide rail, reducing conveying friction and high-temperature wear. The guide wheels 52 on both sides of the support plate 73 are embedded in the slide rail grooves 51, limiting lateral displacement and ensuring conveying stability under high-temperature conditions. The annular structure partition 4 can realize the cyclic conveying of fasteners, which is suitable for the "feed-heating-cooling-discharge" process and does not require an additional return mechanism. The multi-layer independent partitions 4 can simultaneously convey fasteners of different batches and different processing states, saving factory space.

[0047] The high-temperature resistant third motor 66 is started, driving the sprocket 63 to rotate via the connecting shaft 62. This drives the high-temperature resistant chain 61 to circulate along the circular track. The chain pulls the bearing plate 73 and fasteners smoothly through the connecting rod, providing power for conveying. During operation, the tension adjustment mechanism monitors the chain tension in real time. When the chain loosens due to high-temperature deformation or wear, the high-temperature resistant electric telescopic rod 65 drives the slider 64 to move, causing the sprocket 63 to move synchronously, automatically adjusting the chain tension without requiring manual adjustment and ensuring transmission stability and production line continuity.

[0048] When fasteners need to be transferred across layers or regions, the walking component 21 of the transfer mechanism 2 moves along the overhead rail 1 to the end of the target layer; the high-temperature resistant first motor 22 drives the vertical rod 24 to rotate, adjusting the orientation of the pick-and-place fork 27; the high-temperature resistant second motor 23 drives the screw 25 to rotate, causing the slide plate 26 and the pick-and-place fork 27 to rise and fall to the corresponding height of the bearing plate 73; the high-temperature resistant cylinder 28 pushes the pick-and-place fork 27 to extend and retract, inserting it into the bottom of the bearing plate 73 to complete the picking or placing of materials, realizing the process connection between different layers and different conveyor frames.

[0049] After the fasteners are loaded onto the carrier component 7, information such as the fastener specifications, preset heat treatment process, and target workstation is written into a high-temperature resistant RFID tag on the side wall of the carrier plate 73. When the transfer mechanism 2 picks up and puts in materials, the RFID reader at the front end of the slide plate 26 reads the tag information, confirms the identity of the fasteners and the processing requirements, and feeds it back to the intelligent scheduling system to achieve precise transfer. At the same time, it updates the heat treatment status information, which facilitates full traceability and avoids mixing and misordering of materials.

[0050] The intelligent scheduling system collects RFID tag information, load data of the carrying component 7, obstacle signals, and process progress information in real time. It dynamically plans the operating path of the transfer mechanism 2 using a built-in algorithm and matches the power distribution strategy of the drive mechanism 6.

Based on load and high-temperature parameters, the chain tension is adjusted to balance energy saving and stability, achieving intelligent control of the entire process. The above description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above figures and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
