Description

Technical Field

[0001] The present invention relates to the technical field of connecting devices, and specifically to a hot riveting device for industrial Internet of Things production. Background Art

[0002] The hot riveting process requires high-temperature riveting of products, and the entire structure has to withstand high temperatures and be able to transmit large pressures.

[0003] In the prior art, industrial Internet of Things technology is often combined with hot riveting devices to integrate the heating and riveting processes and incorporate industrial Internet of Things technology. It locally heats and softens the rivets or workpieces through heating elements, then uses mechanical pressure to rivet and fix them, and at the same time realizes functions such as remote monitoring, fault warning, and data acquisition and analysis of the equipment with the help of Internet of Things technology, improving the level of production intelligence.

[0004] However, in the existing hot riveting process, there is a problem that the alignment accuracy between the riveting head and the material is insufficient, resulting in inaccurate hot melting positions and affecting the hot riveting effect. At the same time, there are relatively large potential safety hazards.

[0005] Based on this, designing a hot riveting device that meets the requirements of the hot riveting process and improves the alignment accuracy between the riveting head and the material is an urgent problem for us to solve. Summary of the Invention

[0006] The purpose of the present invention is to provide a hot riveting device for industrial Internet of Things production, which uses a hot riveting seat to accommodate and limit the material, and adjusts and aligns the accuracy through a telescopic structure to achieve rapid alignment between the material and the riveting head.

[0007] The purpose of the present invention is mainly achieved through the following technical solutions: A hot riveting device for industrial Internet of Things production, comprising: A workbench; A driving structure, which is fixed on the workbench and is used to provide driving force for the hot riveting device; A hot riveting structure, which is connected to the driving structure and is used to contact and hot melt the breathable membrane; A riveting seat, which is located below the hot riveting structure and is slidably connected to the workbench, and is used to accommodate the workpiece; A telescopic structure, which is arranged on the workbench and is located below the hot riveting structure. The telescopic end of the telescopic structure is connected to the riveting seat and can drive the riveting seat to move reciprocally.

[0008] Existing hot riveting devices often involve problems such as manually picking up materials and manually operating the riveting head. There are issues with insufficient alignment accuracy between the riveting head and the material, resulting in inaccurate melting positions, affecting the hot riveting effect, posing safety hazards, causing stress concentration, uneven loading, etc. At the same time, it is impossible to ensure the temperature and pressure requirements of the device for material processing.

[0009] This device is used for the high-temperature hot riveting connection of the breathable film and the workpiece, and is provided with: A workbench, serving as a basic support structure, is used to fix and carry other components.

[0010] A driving structure, according to different workpieces and hot riveting requirements, controls the magnitude of the pressure and the pressing time to ensure the consistency and reliability of the hot riveting effect.

[0011] A hot riveting structure, connected to the driving structure, is the part used for direct contact with the breathable film and performing the melting operation. Its interior includes heating elements such as electric heating wires or heating blocks, which can melt the breathable film at high temperature and bond it to the product.

[0012] A riveting seat: located below the hot riveting structure and slidably connected to the workbench. It is used to place and position the workpiece to be processed, ensuring the stability of the workpiece during the hot riveting process, and is also convenient for replacement and adjustment.

[0013] A telescopic structure: installed on the workbench, located below the hot riveting structure, and its telescopic end is connected to the riveting seat. The telescopic structure can drive the riveting seat to move, realizing the position movement of the workpiece, so as to align the hot riveting device or for quick loading and unloading.

[0014] Specifically, place the workpiece in the riveting seat to ensure the accurate position of the workpiece. Adjust the telescopic structure to move the riveting seat to the designated position below the hot riveting structure. Start the driving structure to provide the required pressure for the hot riveting structure, and start the heating element in the hot riveting structure to heat the riveting head. When the temperature of the riveting head reaches the hot riveting temperature, turn on the hot riveting structure to start the hot riveting process. After the hot riveting is completed, the telescopic structure automatically moves the riveting seat out of the hot riveting area and takes out the processed workpiece.

[0015] Use the hot riveting seat to accommodate the workpiece, make the hot riveting seat located directly below the hot riveting structure, and be linearly slidably connected to the workbench. Set the telescopic structure to connect the hot riveting seat, so that the telescopic direction of the telescopic structure is the same as the sliding direction of the hot riveting seat, so that the telescopic structure can drive the hot riveting seat to move, enabling the material on the hot riveting seat to align with the hot riveting structure, facilitating riveting.

[0016] Furthermore, the hot riveting structure includes a riveting head, a force transmission steel plate is connected above the riveting head, and a heat insulation layer is provided between the riveting head and the force transmission steel plate; A temperature sensing probe is connected to the riveting head, and a heat preservation layer is provided between the heat insulation layer and the riveting head; The driving structure is connected to the force - transmitting steel plate.

[0017] The hot riveting structure usually includes a heating element and a riveting head. When the riveting head works at a high temperature of 350 °C, the components such as supports, connections, and drives that are in direct or indirect contact with the riveting head may also heat up due to heat conduction. This will affect the structural accuracy of the hot riveting device. Moreover, if the device components deform due to heating, it may lead to problems such as poor bonding of the breathable membrane, inaccurate product positioning, or uneven pressure transmission, thus affecting the quality and performance of the final product.

[0018] The hot riveting structure of this high - temperature hot riveting device mainly includes a riveting head, a heating element, a force - transmitting steel plate, a heat - insulating layer, a heat - preserving layer, and a temperature - sensing probe. The riveting head is used to directly contact and melt the breathable membrane to achieve the connection between the workpiece and the breathable membrane; the heating element is used to heat the riveting head, the force - transmitting steel plate connects the riveting head and the driving structure to transmit pressure to the riveting head. The heat - preserving layer is used to wrap the heating element to reduce heat dissipation. The heat - insulating layer is arranged between the heating element and the force - transmitting steel plate to prevent heat from being transmitted to the force - transmitting steel plate and protect the driving structure from the influence of high temperature. In addition, a temperature - sensing probe is connected to the riveting head to monitor the hot riveting temperature in real time and ensure the hot riveting effect.

[0019] When the hot riveting structure is working, the driving structure exerts pressure downward, and transmits the pressure to the riveting head through the force - transmitting steel plate. Under the action of pressure, the riveting head contacts the breathable membrane, and at the same time, the heating element heats up the riveting head to melt the breathable membrane to achieve the bonding of the breathable membrane and the material. The heat - insulating layer is used to block heat transfer and protect the equipment. The heat - preserving layer is used for heat preservation to prevent the temperature of the riveting head from rapidly dropping during use, resulting in the need for reheating. The temperature - sensing probe monitors the temperature in real time and feeds back to the control system to ensure the precise control of the hot riveting temperature.

[0020] The dual design of the heat - insulating layer and the heat - preserving layer effectively protects the equipment from the influence of high temperature and ensures the temperature stability during the hot riveting process.

[0021] Furthermore, it also includes a conveying structure. The conveying structure is fixed on the workbench and has a gap with the riveting seat. A material - pushing structure is arranged on the conveying structure, and the material - pushing structure can pass over the conveying structure and the riveting seat.

[0022] In the existing hot riveting devices, manual material loading and unloading are often adopted, with poor alignment accuracy and safety risks. If a fool - proof design with double buttons is set, the riveting efficiency is low, and the number of materials that can be riveted by heating the riveting head once is reduced.

[0023] This solution sets up a conveying structure to carry and convey materials near the hot riveting structure. The pusher structure is used to push the materials on the conveying structure onto the riveting seat. The telescopic structure contracts to bring the riveting seat under the riveting head for riveting. After riveting, the telescopic structure pushes the riveting seat close to the conveying structure. The pusher structure pushes the riveted materials onto the conveying structure and pushes the unriveted materials on the conveying structure onto the riveting seat again. By repeating the above operations, the automatic pushing and riveting of materials are realized, reducing manual intervention and improving production efficiency.

[0024] Furthermore, the conveying structure includes a frame body, and a conveyor belt is arranged on the frame body. The conveying direction of the conveyor belt is perpendicular to the telescopic direction of the telescopic structure.

[0025] Specifically, the frame body is connected to the workbench and used to set the conveyor belt, so that the height of the conveyor belt is at the same horizontal plane as the height of the riveting seat, which is convenient for the pusher structure to push the materials in or out of the riveting seat.

[0026] If the moving directions of the conveyor belt and the telescopic structure are the same or similar, there may be a situation where the telescopic structure interferes with the materials being conveyed during telescoping, resulting in the materials being pushed off or the telescopic structure being stuck. The perpendicular setting effectively avoids this potential collision risk, ensuring that the materials can move smoothly on the conveyor belt, and at the same time, the telescopic structure can also perform telescopic actions smoothly.

[0027] Furthermore, the pusher structure includes a rotating part and a pusher plate. The rotating part is rotatably connected to the frame body, and the rotating part and the pusher plate are fixedly connected by a connecting rod. The pusher plate can rotate around the axis of the rotating part, and a material passing channel is arranged on the riveting seat, and the material passing channel can accommodate the pusher plate to pass through.

[0028] Using the rotating part to rotate the pusher plate to push the materials to change their positions, compared with using manual or robotic arms to pick and place materials, the structure of this solution is simpler and the cost is lower.

[0029] Specifically, during implementation, the rotation speed is adjusted according to the moving speeds of the telescopic structure and the conveying structure to increase the coordination between the various component structures.

[0030] Furthermore, two openings are left on the frame body, and the openings can accommodate the pusher plate to pass through. The conveying structure is successively provided with a second conveyor belt and a first conveyor belt along the conveying direction. The second conveyor belt and the first conveyor belt are on the same straight line, and the distance between the two openings is greater than or equal to the distance between the second conveyor belt and the first conveyor belt. There is a material leakage opening between the second conveyor belt and the first conveyor belt. A third conveyor belt is provided below the material leakage opening, and the conveying direction of the third conveyor belt is opposite to that of the second conveyor belt.

[0031] To ensure that the material is accurately pushed to the designated location, the upper surface of the frame body is higher than the upper surface of the conveyor belt. The frame body and the riveting seat leave openings and a material passing channel according to the rotation trajectory of the pushing plate, so that the pushing plate can push the material along the material passing channel to the designated position.

[0032] There are three conveyor belts arranged on the frame body. The second conveyor belt and the first conveyor belt are arranged along the material transmission direction, and the central axes of the second conveyor belt and the first conveyor belt are on the same straight line. There is a material leakage opening between the second conveyor belt and the first conveyor belt. Taking the conveying direction of the conveyor belt as the length direction, the length of the frame body between the two openings is greater than or equal to the length of the material leakage opening.

[0033] The conveying speed of the first conveyor belt is adjusted according to the rotation speed of the rotating part, so that only one material can be pushed into the material passing channel of the riveting seat when a pushing plate rotates once. The second conveyor belt is used to convey the unriveted materials to the vicinity of the riveting seat. The first conveyor belt is used to send away the riveted materials for subsequent quality inspection and collection. The third conveyor belt is used to send the unriveted materials falling from the material leakage opening back to the feeding place.

[0034] Furthermore, the telescopic structure includes a telescopic part and a connecting part. The telescopic part is fixed on the workbench, and the connecting part is connected to the riveting seat.

[0035] Fix the telescopic part on the workbench to serve as the support basis for the entire telescopic structure to ensure the stability of the work. Drive the connecting part and the connected riveting seat to move and expand accordingly through the expansion and contraction of the telescopic part. Through the expansion and contraction action of the telescopic part and the transmission function of the connecting part, the riveting seat can reciprocate on the workbench, so that the riveting can move the material from the riveting position to the conveying position, thus realizing the automatic conveying and riveting operation of the material.

[0036] Furthermore, the riveting seat includes a seat body. In the middle of the upper surface of the seat body, there is a concave placing seat, which is connected to the material passing channel. A position detector is also provided on the upper surface of the seat body, and the position detector is close to the edge of the seat body.

[0037] The placing seat is concave, which can provide a fixed placing position for the material to be riveted, so that the central position of the placing seat can be aligned with the position of the riveting head, ensuring the alignment accuracy of the material during the riveting process and reducing the riveting quality problems caused by the position deviation of the material.

[0038] The position detector is close to the edge of the seat body and can detect the position change of the riveting seat driven by the telescopic structure in real time, ensuring that the riveting seat can accurately reach the predetermined position in each riveting operation. The position detector is connected to the third controller to control the start and stop of the telescopic structure, thereby realizing error correction and adaptive planning. This helps to maintain the stability of the riveting quality in the continuous production process and reduce the scrap rate caused by position deviation.

[0039] Furthermore, a buffer pad is provided below the storage seat.

[0040] When the hot riveting device is working, high temperature and large pressure are required to melt the riveting head and fit the breathable film to the product. The buffer pad can absorb the impact force generated during the riveting process, prevent the riveting seat from over-compressing the material under high temperature and large pressure, and avoid material deformation or damage. At the same time, the buffer pad can also reduce the vibration of the equipment during operation, improving the stability and accuracy of riveting.

[0041] In summary, the present invention has the following beneficial effects compared with the prior art: 1. The hot riveting seat is used to accommodate and limit the workpiece, and a telescopic structure is provided to connect the hot riveting seat, enabling the telescopic structure to carry the hot riveting seat to move, so that the materials on the hot riveting seat can be aligned with the hot riveting structure, facilitating riveting; 2. The hot riveting structure includes a heat insulation layer and a heat preservation layer, which effectively protects the equipment from high temperature; a temperature sensing probe is provided to monitor the hot riveting temperature, realizing precise temperature control and ensuring the consistency of the hot riveting effect; 3.

Detailed implementation manners

[0043] In order to make the objectives, technical solutions and advantages of the present invention more clear and understandable, the present invention will be further described in detail below with reference to the embodiments and the drawings. The illustrative embodiments of the present invention and their descriptions are only used to explain the present invention and are not intended to limit the present invention.

[0044] Embodiment: As Figures 1 - 5 shown, the present embodiment relates to a hot riveting device for industrial Internet of Things production, including: Workbench 6; Driving structure 1, the driving structure 1 is fixed on the workbench 6, and the driving structure 1 is used to provide driving force for the hot riveting device; Hot riveting structure 2, the hot riveting structure 2 is connected to the driving structure 1, and the hot riveting structure 2 is used to contact and melt the breathable film; Riveting seat 3, the riveting seat 3 is located below the hot riveting structure 2 and is slidably connected to the workbench 6, and the riveting seat 3 is used to accommodate workpieces; Telescopic structure 7, the telescopic structure 7 is arranged on the workbench 6 and is located below the hot riveting structure 2, and the telescopic end of the telescopic structure 7 is connected to the riveting seat 3 and can drive the riveting seat 3 to move reciprocally.

[0045] Existing hot riveting devices often have problems such as manual material taking and manual operation of the riveting head. There are problems such as insufficient alignment accuracy between the riveting head 206 and the material, resulting in inaccurate melting positions, affecting the hot riveting effect, posing safety hazards, causing stress concentration, uneven loading, etc. At the same time, it is impossible to ensure the temperature and pressure requirements of the device for material processing.

[0046] Taking the process requirements of melting the breathable film at a high temperature of 350 °C and making the breathable film fit with the material, and at the same time the entire structure is required to transmit a maximum pressure of 2000 N as an example: This device is used for high-temperature hot riveting connection of the breathable film and the workpiece, and is provided with: The workbench 6, as a basic support structure, is used to fix and carry other components.

[0047] The driving structure 1 controls the magnitude of the pressure and the pressing time according to different workpieces and hot riveting requirements, ensuring the consistency and reliability of the hot riveting effect.

[0048] The hot riveting structure 2 is connected to the driving structure 1 and is the part that directly contacts the breathable membrane and performs the hot melting operation. It includes heating elements such as heating wires or heating blocks inside, which can melt the breathable membrane at high temperature and bond it to the product.

[0049] The riveting seat 3 is located below the hot riveting structure 2 and is slidably connected to the workbench 6. It is used to place the workpiece to be processed, ensuring the stability of the workpiece during the hot riveting process and facilitating replacement and adjustment. The shape of the riveting seat 3 can be set according to the shape and size of the workpiece to be processed to support and limit the workpiece to be processed.

[0050] The telescopic structure 7 is installed on the workbench 6, below the hot riveting structure 2, and its telescopic end is connected to the riveting seat 3. The telescopic structure 7 can drive the riveting seat 3 to move, realizing the position movement of the workpiece, so as to align the hot riveting device or quickly load and unload.

[0051] Specifically, place the workpiece in the riveting seat 3 to ensure the accurate position of the workpiece. Adjust the telescopic structure 7 to move the riveting seat 3 to the designated position below the hot riveting structure 2. Start the driving structure 1 to provide the required pressure for the hot riveting structure 2, and start the heating element in the hot riveting structure 2 to heat the riveting head. When the temperature of the riveting head reaches the hot riveting temperature, turn on the hot riveting structure 2 to start the hot riveting process. After the hot riveting is completed, the telescopic structure 7 automatically moves the riveting seat 3 out of the hot riveting area and takes out the processed workpiece.

[0052] Use the hot riveting seat to accommodate the workpiece, make the hot riveting seat located directly below the hot riveting structure 2, and be linearly slidably connected to the workbench 6. Set the telescopic structure 7 to connect the hot riveting seat, so that the telescopic direction of the telescopic structure 7 is the same as the sliding direction of the hot riveting seat, so that the telescopic structure 7 can carry the hot riveting seat to move, so that the material on the hot riveting seat can be aligned with the hot riveting structure 2, facilitating riveting.

[0053] Specifically, when the above device is in specific use, the driving structure 1 can adopt a hydraulic cylinder. The hydraulic system can generate a large pressure, which is suitable for scenarios with high pressure requirements in the high-temperature hot riveting device; in the normal working state of the hot riveting device described in this application, the elongation length of the piston rod of the hydraulic cylinder is proportional to the pressure.

[0054] Furthermore, the hot riveting structure 2 includes a riveting head 206, a force transmission steel plate 202 is connected above the riveting head 206, and a heat insulation layer 203 is provided between the riveting head 206 and the force transmission steel plate 202; A temperature-sensitive probe 205 is connected to the riveting head 206, and a heat-insulating layer 204 is provided between the heat-insulating layer 203 and the riveting head 206; The driving structure 1 is connected to the force-transmitting steel plate 202.

[0055] The hot riveting structure 2 usually includes a heating element and a riveting head 206. When the riveting head 206 is heated to a high temperature of 350 °C for operation, the supporting, connecting, and driving components that are in direct or indirect contact with the riveting head 206 may also heat up due to heat conduction. This may affect the structural accuracy of the hot riveting device. Moreover, if the device components are deformed due to temperature rise, problems such as poor adhesion of the breathable film, inaccurate product positioning, or uneven pressure transmission may occur, thus affecting the quality and performance of the final product.

[0056] The hot riveting structure 2 of this high-temperature hot riveting device mainly includes a riveting head 206, a heating element, a force-transmitting steel plate 202, a heat-insulating layer 203, a heat-insulating layer 204, and a temperature-sensitive probe 205. The riveting head 206 is used to directly contact and melt the breathable film to realize the connection between the workpiece and the breathable film; the heating element is used to heat the riveting head 206, and the force-transmitting steel plate 202 connects the riveting head 206 and the driving structure 1 to transmit the pressure to the riveting head 206. The heat-insulating layer 204 is used to wrap the heating element to reduce heat dissipation. The heat-insulating layer 203 is arranged between the heating element and the force-transmitting steel plate 202 to prevent heat from being transmitted to the force-transmitting steel plate 202 and protect the driving structure 1 from the influence of high temperature. In addition, a temperature-sensitive probe 205 is connected to the riveting head 206 to monitor the hot riveting temperature in real time and ensure the hot riveting effect.

[0057] Specifically, the temperature-sensitive probe 205 is electrically connected to a first controller, and the first controller is electrically connected to the heating element. The temperature-sensitive probe 205 is used to monitor the hot riveting temperature in real time and feedback the detected temperature to the first controller. It realizes the dynamic control of the temperature of the riveting head 206, ensures that the riveting head 206 is always at an appropriate hot riveting temperature, and guarantees the consistency of the hot riveting effect.

[0058] When the hot riveting structure 2 is working, the driving structure 1 applies downward pressure, and the pressure is transmitted to the riveting head 206 through the force-transmitting steel plate 202. The riveting head 206 contacts the breathable film under the action of pressure, and at the same time, the heating element heats up the riveting head 206 to melt the breathable film to realize the adhesion of the breathable film and the material. The heat-insulating layer 203 is used to prevent heat transfer and protect the equipment. The heat-insulating layer 204 is used for heat preservation to prevent the temperature of the riveting head 206 from rapidly dropping during use and requiring re-heating. The temperature-sensitive probe 205 monitors the temperature in real time and feeds it back to the control system to ensure the precise control of the hot riveting temperature.

[0059] The dual design of the heat-insulating layer 203 and the heat-insulating layer 204 effectively protects the equipment from the influence of high temperature and ensures the temperature stability during the hot riveting process.

[0060] When the above solution is implemented specifically: A brass material can be used to make the riveting head 206, taking into account both cost and high thermal conductivity efficiency. Asbestos is used as the thermal insulation layer 204 to wrap the exposed part of the brass and reduce heat dissipation. Mica material is used as the heat insulation layer 203 to separate the contact between the riveting head 206 and other components, reduce heat transfer, and avoid high temperature affecting the structural accuracy. Ensure that when the riveting head 206 works at a high temperature of three hundred and fifty °C, other components of the device do not have obvious temperature rise. The driving structure 1 is a cylinder, and the force transmission steel plate 202 is threadedly connected to the end of the cylinder piston rod.

[0061] When the above solution is implemented specifically: There is a protruding screw above the force transmission steel plate 202 of the hot riveting structure 2. When the hot riveting structure 2 is not assembled and used, a fixing nut 201 is connected to the screw.

[0062] Furthermore, it also includes a conveying structure 5. The conveying structure 5 is fixed on the workbench 6 and has a gap with the riveting seat 3. A material pushing structure 4 is arranged on the conveying structure 5, and the material pushing structure 4 can pass over the conveying structure 5 and the riveting seat 3.

[0063] In existing hot riveting devices, manual material picking and placing are often adopted, with poor alignment accuracy and safety risks. If a double-button anti-fooling design is set, the riveting efficiency is low.

[0064] In this solution, the conveying structure 5 is set to carry and convey materials to near the hot riveting structure 2. The material on the conveying structure 5 is pushed onto the riveting seat 3 through the arranged material pushing structure 4, and the telescopic structure 7 contracts to bring the riveting seat 3 below the riveting head 206 for riveting. After riveting is completed, the telescopic structure 7 pushes the riveting seat 3 close to the conveying structure 5, and the material pushing structure 4 pushes the riveted material onto the conveying structure 5 and pushes the unriveted material on the conveying structure 5 onto the riveting seat 3 again. By circulating the above operations, automatic material pushing and riveting operations are realized, reducing manual intervention and improving production efficiency.

[0065] Furthermore, the conveying structure 5 includes a frame body 501. A conveyor belt is arranged on the frame body 501, and the conveying direction of the conveyor belt is perpendicular to the telescopic direction of the telescopic structure 7.

[0066] Specifically, the frame body 501 is set to be connected to the workbench 6 and used to set the conveyor belt, so that the height of the conveyor belt is at the same horizontal plane as the height of the riveting seat 3, which is convenient for the material pushing structure 4 to push the material out of or into the riveting seat 3.

[0067] If the moving directions of the conveyor belt and the telescopic structure 7 are the same or similar, it may occur that the telescopic structure 7 interferes with the materials being conveyed during telescoping, resulting in the materials being pushed off or the telescopic structure 7 being stuck. The vertical setting effectively avoids this potential collision risk, ensuring that the materials can move smoothly on the conveyor belt, while the telescopic structure 7 can also perform telescopic actions smoothly.

[0068] Furthermore, the pusher structure 4 includes a rotating part 401 and a pusher plate 403. The rotating part 401 is rotatably connected to the frame body 501, and the rotating part 401 and the pusher plate 403 are fixedly connected through a connecting rod 402. The pusher plate 403 can rotate around the axis of the rotating part 401. A material passing channel 305 is provided on the riveting seat 3, and the material passing channel 305 can accommodate the pusher plate 403 to pass through.

[0069] Using the rotating part 401 to rotate the pusher plate 403 to push the materials to change their positions, compared with using manual or robotic arms to pick and place materials, the structure of this solution is simpler and the cost is lower.

[0070] Specifically, during implementation, the rotation speed is adjusted according to the moving speeds of the telescopic structure 7 and the conveying structure 5 to increase the coordination between the various component structures. The working states of the driving structure 1 and the pusher structure 4 are independent of each other: the driving structure 1 drives the riveting seat 3 to move until the riveting seat 3 is close to the conveying structure 5, and then both the driving structure 1 and the riveting seat 3 are stationary. At this time, the pusher structure 4 starts to work, that is, the driving structure 1 and the pusher structure 4 do not interfere with each other.

[0071] When the above solution is specifically implemented, two pusher plates 403 can be symmetrically arranged and rotate 180 degrees when picking and placing materials once.

[0072] Furthermore, two openings are left on the frame body 501, and the openings can accommodate the pusher plate 403 to pass through; The conveying structure 5 is successively provided with a second conveyor belt 504 and a first conveyor belt 502 along the conveying direction. The second conveyor belt 504 and the first conveyor belt 502 are on the same straight line, and the distance between the two openings is greater than or equal to the distance between the second conveyor belt 504 and the first conveyor belt 502; A material leakage opening 503 is provided between the second conveyor belt 504 and the first conveyor belt 502, and a third conveyor belt 505 is provided below the material leakage opening 503. The conveying direction of the third conveyor belt 505 is opposite to that of the second conveyor belt 504.

[0073] To ensure that the materials are accurately pushed to the designated location, the upper surface of the frame 501 is higher than the upper surface of the conveyor belt. An opening and a material passing channel 305 are left between the frame 501 and the riveting seat 3 according to the rotation trajectory of the pushing plate 403, so that the pushing plate 403 can push the materials along the material passing channel 305 to the designated position.

[0074] Three conveyor belts are arranged on the frame 501. The second conveyor belt 504 and the first conveyor belt 502 are arranged along the material transmission direction. The central axes of the second conveyor belt 504 and the first conveyor belt 502 are on the same straight line. There is a material leakage opening 503 between the second conveyor belt 504 and the first conveyor belt 502. Taking the transmission direction of the conveyor belt as the length direction, the length of the frame 501 between the two openings is greater than or equal to the length of the material leakage opening 503.

[0075] The transmission speed of the first conveyor belt 502 is adjusted according to the rotation speed of the rotating part 401, so that only one material can be pushed into the material passing channel 305 of the riveting seat 3 when a pushing plate 403 rotates once. The second conveyor belt 504 is used to convey the un-riveted materials to the vicinity of the riveting seat 3. The first conveyor belt 502 is used to send away the riveted materials for later quality inspection and collection. The third conveyor belt 505 is used to send the un-riveted materials falling from the material leakage opening 503 back to the feeding place.

[0076] When the above scheme is specifically implemented: A position detector is arranged on the frame 501 near the driven end of the second conveyor belt 504. The position detector is used to detect the distance between the riveting seat 3 and the frame 501. The position detector is connected to a second controller, and the second controller can control the start and stop of the rotating part 401. The vibrating disk feeding is connected to the driving end of the second conveyor belt 504. The second conveyor belt 504 is used to convey the un-riveted materials. At this time, the pushing plate 403 is located at the opening of the frame 501, and the plate surface of the pushing plate is parallel to the length direction of the frame 501. Two pushing plates 403 are symmetrically connected to the rotating part 401.

[0077] When the in-place detector detects that the riveting seat 3 approaches the frame 501, the second controller controls the rotation of the rotating part 401, so that the pushing plate 403 rotates from the material leakage port 503 towards the second conveyor belt 504, pushing the material to reach the opening on the frame 501 and the material passing channel 305 on the riveting seat 3 in sequence. After that, the pushing plate 403 returns to the opening on the frame 501 again and stops rotating. Specifically, rollers are arranged on the material passing channel 305. After the material reaches the material passing channel 305, it continues to move forward on the rollers by inertia to the riveting position on the riveting seat 3. After the telescopic structure 7 drives the riveting seat 3 to retract and the material is riveted by the hot riveting structure 2, when the riveting seat 3 extends to approach the frame 501 again, the rotating part 401 rotates again, so that one of the pushing plates 403 rotates from the opening to the riveting seat 3 and then to the other opening, pushing the riveted workpiece onto the first conveyor belt 502, and the other pushing plate 403 rotates from the opening close to the first conveyor belt 502 to the second conveyor belt 504, pushing an unriveted material through the opening to the material passing channel 305 and finally reaching the riveting position.

[0078] As an implementable solution of the above solution, for materials that are not easily deformed and not afraid of being dropped or pressed, they directly fall from the material leakage port 503 onto the third conveyor belt 505. For materials that are easily deformed and damaged, a lifting structure is arranged on the support frame of the third conveyor belt 505 below the material leakage port 503, which is used to receive the unhot-riveted material and descend smoothly, so that the unhot-riveted material falls onto the third conveyor belt 505. Specifically, the lifting structure includes a product that can be lifted, such as a cylinder and a telescopic rod. A material tray for holding the material is rotatably connected above the lifting product, and a push rod is arranged below the material tray. When the material tray does not contact the push rod, it is in a horizontal state on the lifting product due to gravity. When the lifting product descends and the material tray contacts the push rod, the material tray rotates to unload the material, which is used to improve the product qualification rate. It should be noted that for easily deformed materials with high precision requirements, a special material clamping and transfer device still needs to be used.

[0079] As a preferred solution of the above implementable solution, a weight sensor is arranged at the bottom of the material tray, and the weight sensor is electrically connected to the controller of the lifting product. When the weight sensor on the material tray senses that the material on the material tray reaches a certain mass, the lifting product descends. After the bottom of the material tray contacts the push rod, the material tray rotates longitudinally to unload the material. After the weight sensor senses that there is no material on the material tray, it controls the lifting product to rise until the material tray leaves the push rod, returns to the horizontal state and approaches the material leakage port 503.

[0080] As an alternative to the above solution, the material passing channel 305 is connected to the opening, and both the material passing channel 305 and the opening coincide with the movement track of the pushing plate 403. The overall length of the pushing plate 403 and the connecting rod 402 requires that the pushing plate 403 can just push the materials at the conveyor belt and the riveting position. The material passing channel 305 in this solution, such as the patent with the publication number CN219970809U, is provided with a number of rollers to provide power and guidance for the movement of the materials. The laying direction of the rollers points from the opening to the riveting position at the center of the riveting seat 3, enabling the materials to move forward to the riveting position through the rotation of the rollers; or adopt the structure of the adjusting device in the publication number CN117985421A to send the materials to the riveting position at the center of the riveting seat 3.

[0081] If only the rollers are laid and no power sources such as motors are set for the rollers, then the rotation speed of the rotating part 401 needs to be controlled to ensure that after the materials reach the rollers on the material passing channel 305, they can still reach the riveting position on the riveting seat 3 by inertial drive. During actual use, the riveting position is sunken, and the sunken shape is set according to the shape of the materials to ensure that the materials can stop moving and be limited after reaching the riveting position.

[0082] Furthermore, the telescopic structure 7 includes a telescopic part 701 and a connecting part 702. The telescopic part 701 is fixed on the workbench 6, and the connecting part 702 is connected to the riveting seat 3.

[0083] Fixing the telescopic part 701 on the workbench 6 serves as the support basis for the entire telescopic structure 7 to ensure the stability of the work. The telescopic movement of the telescopic part 701 drives the connecting part 702 and the connected riveting seat 3 to perform corresponding moving telescoping. Through the telescopic action of the telescopic part 701 and the transmission function of the connecting part 702, the riveting seat 3 can reciprocate on the workbench 6, so that the riveting can move the materials from the riveting position to the conveying position, thereby realizing the automatic conveying and riveting operations of the materials.

[0084] Specifically, the telescopic structure 7 can adopt an electric push rod, a cylinder or a hydraulic cylinder.

[0085] Furthermore, the riveting seat 3 includes a seat body 302. In the middle of the upper surface of the seat body 302, there is a concave placing seat 303. The placing seat 303 is connected to the material passing channel 305. On the upper surface of the seat body 302, there is also a position detector 301, and the position detector 301 is close to the edge of the seat body 302.

[0086] The placing seat 303 is concave, which can provide a fixed placing position for the materials to be riveted, enabling the central position of the placing seat 303 to align with the position of the riveting head 206, ensuring the alignment accuracy of the materials during the riveting process, and reducing the riveting quality problems caused by the position deviation of the materials.

[0087] The position detector 301 is close to the edge of the base 302 and can detect the position change of the riveting base 3 driven by the telescopic structure 7 in real time, ensuring that the riveting base 3 can accurately reach the predetermined position in each riveting operation. The position detector 301 is connected to the third controller and is used to control the start and stop of the telescopic structure 7, thereby realizing error correction and adaptive planning. This helps to maintain the stability of the riveting quality during the continuous production process and reduce the rejection rate caused by position deviation.

[0088] In specific implementation, the shape of the storage seat 303 can be matched with that of the material, so that when the material enters the storage seat 303, it can automatically enter the central position and fit with the storage seat 303, and the position is more stable during the riveting process.

[0089] Furthermore, a buffer pad 304 is provided below the storage seat 303.

[0090] When the hot riveting device is working, high temperature and large pressure are required to melt the breathable film by the riveting head 206 and fit it with the product. The buffer pad 304 can absorb the impact force generated during the riveting process, prevent the riveting base 3 from over-extruding the material under high temperature and large pressure, and avoid material deformation or damage. At the same time, the buffer pad 304 can also reduce the vibration of the equipment during operation and improve the stability and accuracy of riveting.

[0091] The above specific implementation manners have further detailed the purpose, technical solutions and beneficial effects of the present invention. It should be understood that the above are only the specific implementation manners of the present invention and are not used to limit the protection scope of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
