Description

Technical Field

[0001] This invention belongs to the technical field of parts sorting and transportation equipment, and specifically relates to a bolt and nut sorting and transportation equipment for parts processing. Background Technology

[0002] The motorcycle frame is the core load-bearing structure of a motorcycle. Its manufacturing process involves multiple steps, including tubing cutting, bending, welding, and assembly, with welding being the most critical step. The frame is formed by welding together multiple sections of tubing of different specifications, connecting supports, and reinforcing components. Welding stations are located in different areas of the frame, including the front connection area, the load-bearing area, and the rear suspension area. Each station requires specific bolts, nuts, screws, and other fasteners for temporary fixation during welding and reinforcement during subsequent component assembly.

[0003] To ensure the continuity of frame welding, the front end needs to sort, directionally transport, and package various fasteners in designated areas. This ensures that each welding station receives the corresponding parts as needed, avoiding production delays caused by mismatched material specifications or supply delays. Currently, in motorcycle frame component processing, most manufacturers rely on manual labor for sorting and handling bolts and nuts, using simple fixed hoppers and ordinary conveyor belts for basic transport. A few manufacturers use simple vibrating feeding devices with single-channel sorting structures, which can only handle fasteners of a single specification, and the entire process of replenishing output containers and transferring full containers relies on manual operation.

[0004] Existing technology uses a vibratory feeder for directional feeding and a fixed screen for screening to complete the conveying of fasteners of a single specification. This is only suitable for conveying batches of fasteners of a single specification and cannot meet the needs of sorting fasteners of multiple specifications and multiple channels.

[0005] The existing technology has at least the following problems in use: the existing equipment has poor adaptability and cannot meet the requirements of sorting fasteners of multiple stations and specifications, and it is difficult to realize multi-channel zoned conveying; manual sorting is inefficient and prone to missorting and omission, and manual handling of containers is labor-intensive; the simple feeding structure is prone to component jamming and unstable conveying, and cannot realize orderly intermittent conveying of components. Summary of the Invention

[0006] This invention provides a bolt and nut sorting and transporting device for parts processing, which solves the technical problem of low efficiency in parts conveying and sorting in the prior art.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solution: A bolt and nut sorting and transporting device for parts processing includes: a frame having a first mounting area and a second mounting area; a feeding assembly installed in the first mounting area, the feeding assembly including a detachable feeding box, a feeding platform, and a feeding unit, the feeding unit being equipped with a single electrically driven roller for intermittently transferring parts; a stacking platform located at the output end of the feeding assembly, which transports and receives parts transferred by the feeding unit via a pulley; a first transfer assembly installed on the side of the stacking platform, equipped with transfer claws for multi-channel transfer of parts; a container feeding assembly installed in the second mounting area, including two staggered lifting units and a conveyor belt equipped with limit strips, the lifting units being used for loading and unloading output containers, and the conveyor belt being used for replenishing or outputting the output containers; and a second transfer assembly mounted on the frame for transferring the output containers filled with parts from the sorting platform to the container feeding assembly.

[0008] Furthermore, the feeding box and the feeding platform are connected by a snap-fit ​​detachable connection, and the inner wall of the feeding box is provided with an anti-slip structure to prevent parts from getting stuck or damaged by bumps.

[0009] Furthermore, the feeding unit includes a single electrically driven roller with spaced limiting structures on its surface. The spacing of the limiting structures is adapted to the size of bolts and nuts of different specifications, so as to realize stable interval conveying of individual parts.

[0010] Furthermore, the first transfer component includes a lateral moving module and a longitudinal telescopic module. The transfer claw is fixed at the end of the longitudinal telescopic module and adopts an elastic clamping structure, which can adaptively clamp bolts and nuts of different specifications.

[0011] Furthermore, the two lifting units of the container feeding assembly are staggered along the length of the conveyor belt. When one lifting unit performs the empty container feeding action, the other lifting unit simultaneously performs the full container unloading action, realizing continuous switching of container supply.

[0012] Furthermore, the limiting strips of the conveyor belt are detachable connection structures, and the spacing between the limiting strips can be flexibly adjusted according to the actual width of the output container to ensure stable positioning and no deviation during the container conveying process.

[0013] Furthermore, the second transfer component includes a gantry, a horizontal sliding module, and an adsorption clamp. The adsorption clamp is used to adsorb and fix the output container, and the horizontal sliding module enables the container to be smoothly transferred between the sorting platform and the container loading component.

[0014] Furthermore, the sorting platform includes multiple sorting conveyor plates, which are evenly spaced apart, and the number and position of the output containers are synchronously set to correspond to the distribution of the sorting conveyor plates.

[0015] Furthermore, the output container is detachably connected to the first mounting area via a fixing clip.

[0016] Furthermore, it also includes multiple pressure sensors and position sensors. The pressure sensors are installed at the bottom of the output container to collect the total mass of the collected parts, thereby converting it into the loading quantity. The position sensors are correspondingly set in specific distribution areas of the output container to guide the second transfer component to transfer the corresponding output container.

[0017] This invention provides a bolt and nut sorting and transporting equipment for parts processing, with the following advantages: A detachable feeding box and a single electrically driven roller with a limiting structure enable stable, spaced feeding of bolts and nuts, preventing parts jamming and adapting to the transport needs of parts of different specifications; a multi-channel elastic clamping first transfer component matches the multi-station parts sorting requirements of motorcycle frames, achieving precise zoned transport of parts of various specifications, replacing manual sorting and reducing the error rate; an interlaced lifting unit and an adjustable limiting strip conveyor belt enable automatic replenishment of output containers and continuous output of full containers, eliminating the need for manual handling and reducing labor intensity; and a gantry-type second transfer component enables automated, stable transfer and unified collection of full containers, improving the overall automation level of the equipment and adapting to the needs of large-scale, continuous welding processing of motorcycle frames.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0025] Example: As shown in Figure 1 to Figure 8 As shown, this embodiment provides a bolt and nut sorting and transporting equipment for parts processing, including: a frame 1, having a first installation area 11 and a second installation area 12; a feeding assembly 2, installed in the first installation area 11, the feeding assembly 2 including a detachable feeding box 21, a feeding platform 22 and a feeding unit, the feeding unit being provided with a single electrically driven roller 231 for intermittently transferring parts; a stacking platform 3, located at the output end of the feeding assembly 2, conveying the parts transferred by the feeding unit via a pulley 31; a first transfer assembly 4, installed on the side of the stacking platform 3, being provided with a transfer claw 41 for multi-channel transfer of parts; a container feeding assembly 5, installed in the second installation area 12, including two staggered lifting units 51 and a conveyor belt 52 with a limit bar 521, the lifting units 51 being used for loading and unloading the output container 8, and the conveyor belt 52 being used for replenishing or outputting the output container 8; and a second transfer assembly 6, mounted on the frame 1, for transferring the output container 8 filled with parts on the sorting platform 7 to the container feeding assembly 5.

[0026] In this embodiment, the frame 1 is welded; the first installation area 11 is located on one side of the frame 1 and has reserved installation and positioning holes for the feeding component 2 and the stacking platform 3; the second installation area 12 is located on the other side of the frame 1 and is used to integrate the container feeding component 5; the bottom of the frame 1 is provided with adjustable feet to adjust the level of the equipment and ensure the running accuracy of each moving part.

[0027] The material stacking station 3 also includes a feeding support bar 331, a clamping slide rail 332, a sliding seat 333, a clamping column 334, a pressure sensor 335, a lifting support plate 336, and a lifting drive seat 337.

[0028] The feeding support bar 331 is fixed on the platform surface of the stacking table 3 along the distribution direction of the stacking table 3, and is used to support the parts conveyed by the pulley 31 and provide a reference plane for stacking. There are two sets of clamping slide rails 332, distributed on both sides of the feeding support bar 331, and the two sets of clamping slide rails 332 are respectively arranged along the width direction of the stacking table 3. The two sliding seats 333 can move left and right synchronously along the clamping slide rails 332, and the two sliding seats 333 clamp from both sides towards the direction close to the feeding support bar 331. The clamping and releasing are realized by the ball screw servo drive of the two sliding seats 333. The clamping column 334 is vertically installed on the sliding seat 333, which can center and clamp the parts conveyed to the end of the stacking table 3. Pressure sensors 335 are also provided on the surface of the clamping column 334 and the parts in contact. The upper part is used to provide feedback and detect whether there are any parts in front of the current clamping column 334, thereby realizing the quantity detection of columnar parts being transferred and sorted on the palletizing platform. When all clamping columns 334 are clamped with parts or workpieces, the electrical signals emitted by the sensors realize the feedback of palletizing completion and a series of signals for transfer. The relevant control system uses the corresponding existing control technology, so it will not be described in detail. A lifting support plate 336 is also installed at the bottom of the feeding support platform to lift the parts out of the reference surface of the feeding support bar 331 and raise the parts to be transferred to a higher position for easy transfer. The lifting drive seat 337 can be a hydraulic or pneumatic telescopic rod, which can drive the lifting support plate 336 to lift the positioned parts to a suitable height for accurate gripping by the first transfer component 4.

[0029] Furthermore, the loading box 21 and the loading platform 22 are connected by a snap-fit ​​detachable connection, and the inner wall of the loading box 21 is provided with an anti-slip structure to prevent parts from getting stuck or damaged by bumps.

[0030] In this embodiment, the bottom of the loading box 21 is provided with a detachable fixing plate. After the fixing plate is pulled out, the parts can slide from the loading box 21 to the electric drive roller 231 below through the connection port 211. The loading box 21 and the loading platform 22 are connected by symmetrically distributed spring buckles. When disassembling, pressing the buckles can quickly remove the parts, which is convenient for emptying the remaining parts or cleaning the box.

[0031] Furthermore, the feeding unit includes a single electrically driven roller 231, the surface of which is provided with spaced limiting structures 232. The spacing of the limiting structures 232 is adapted to the size of bolts and nuts of different specifications, so as to realize stable spaced conveying of individual parts.

[0032] In this embodiment, the electric drive roller 231 is servo-driven. Through existing technology, the electric drive roller 231 can be intermittently or continuously rotated to achieve posture sorting and uniform output. It can be flexibly adjusted according to the specifications of the parts and the sorting speed. For the processing of parts of different sizes and specifications, the electric drive roller 231 of the corresponding specifications can be replaced accordingly to achieve adaptation and fit. In actual use, the part of the feeding unit where the electric drive roller falls is covered with a transparent acrylic sheet to achieve dustproof sealing. Because it is a transparent structure, it is easy for maintenance personnel to inspect and monitor the structure, so as to quickly judge the output status and progress. The limiting structure 232 is an arc groove, which is evenly spaced on the surface of the electric drive roller 231. The distribution spacing of the groove needs to be made according to the corresponding process requirements to ensure that only one part can be transported at a time, effectively preventing subsequent sorting errors and damage caused by multiple parts being mixed.

[0033] Furthermore, the first transfer component 4 includes a lateral moving module 42 and a longitudinal telescopic module 43. The transfer claw 41 is fixed at the end of the longitudinal telescopic module 43. The transfer claw 41 adopts an elastic clamping structure, which can adaptively clamp bolts and nuts of different specifications.

[0034] In this embodiment, the lateral movement module 42 adopts a transmission structure, which has high repeatability and adjustable running speed; the longitudinal telescopic module 43 adopts an electric push rod, which has adjustable telescopic stroke and sufficient thrust; the elastic clamping structure of the transfer claw 41 consists of two symmetrical claws and a built-in compression spring. The inner side of the claw is covered with an anti-slip rubber pad, which can automatically adjust the clamping force when clamping bolts and nuts of different specifications, so as to avoid damaging the coating on the surface of the parts.

[0035] Furthermore, the two lifting units 51 of the container feeding assembly 5 are staggered along the length of the conveyor belt 52. When one lifting unit 51 performs the empty container feeding action, the other lifting unit 51 simultaneously performs the full container unloading action, realizing continuous switching of container supply.

[0036] In this embodiment, the lifting unit 51 adopts a lifting structure with adjustable lifting stroke and sufficient load-bearing capacity, allowing multiple empty containers to be stacked at once. The two lifting units 51 are located at the feeding end and the discharging end of the conveyor belt 52, respectively. The feeding end lifting unit 51 is used to lift the stacked empty containers one by one to the height of the conveyor belt 52, and the discharging end lifting unit 51 is used to lower and stack the full containers filled with parts one by one. The two lifting units 51 operate completely synchronously. When the feeding end lifting unit 51 lowers an empty container, the discharging end lifting unit 51 simultaneously raises a full container, realizing uninterrupted switching of containers without stopping the machine to wait.

[0037] Furthermore, the limiting strips 521 of the conveyor belt 52 are detachable connection structures, and the spacing of the limiting strips 521 can be flexibly adjusted according to the actual width of the output container 8 to ensure stable positioning and no deviation during the container conveying process.

[0038] In this embodiment, the surface of the conveyor belt 52 is provided with anti-slip texture, which can increase the friction between it and the container; the limiting strip 521 is fixed to the slide groove of the frame 1 on both sides of the conveyor belt 52 by bolts. The spacing of the limiting strip 521 can be adjusted left and right by loosening the bolts, which can adapt to output containers 8 of different widths; the inner side of the limiting strip 521 is attached with a wear-resistant strip, which can reduce the friction between the container and the limiting strip 521 and extend its service life.

[0039] Furthermore, the second transfer component 6 includes a gantry 61, a horizontal sliding module 62, and an adsorption clamp 63. The adsorption clamp 63 is used to adsorb and fix the output container 8, and the horizontal sliding module 62 realizes the smooth transfer of the container between the sorting platform 7 and the container loading component 5.

[0040] In this embodiment, the gantry 61 spans across the sorting platform 7 and the container loading assembly 5; the horizontal sliding module 62 adopts linear guide rail transmission, with adjustable running speed and high repeatability positioning accuracy; the adsorption fixture 63 uses multiple vacuum suction cups evenly distributed on the fixture base plate, and generates negative pressure through a vacuum generator to adsorb and output the container 8. The adsorption force is adjustable and can be applied to containers of different weights. The transfer process is smooth and without shaking, avoiding spillage of parts.

[0041] Furthermore, the sorting platform 7 includes multiple sorting conveyor plates, which are evenly spaced apart, and the number and position of the output containers 8 corresponding to the sorting conveyor plates are set synchronously.

[0042] In this embodiment, the number of sorting conveyor plates can be set according to the specifications of commonly used bolts and nuts. The surface of the sorting conveyor plates is smooth and they are set at an angle. The sorting conveyor plates are evenly spaced apart. Each sorting conveyor plate is placed under an output container 8. The first transfer component 4 transfers the parts on the stacking table 3 to the corresponding sorting conveyor plate. The parts automatically slide down the inclined conveyor plate into the output container 8 below, realizing classified collection.

[0043] Furthermore, the output container 8 is detachably connected to the first mounting area 11 via a fixing clip.

[0044] In this embodiment, the side wall of the output container 8 is provided with reinforcing ribs to improve structural strength and prevent deformation after being filled with parts; the bottom of the output container 8 is provided with symmetrical fixing buckles, which are connected to the slots of the first installation area 11. During installation, the container can be fixed by simply aligning it with the slot and pressing it down. During disassembly, it can be removed by lifting it upwards, which facilitates quick container replacement.

[0045] Furthermore, it also includes multiple pressure sensors 335 and position sensors. The pressure sensors 335 are installed at the bottom of the output container 8 to collect the total mass of the collected parts, thereby converting it into the loading quantity. The position sensors are correspondingly set in specific distribution areas of the output container 8 to guide the second transfer component 6 to transfer the corresponding output container 8.

[0046] In this embodiment, the pressure sensor 335 at the bottom of the output container 8 can be a resistance strain gauge sensor. The control system can automatically calculate the loading quantity in the container based on the pre-stored mass of a single component. When the loading quantity reaches the preset value, a full material signal is sent to the control system. The position sensor is a diffuse reflection photoelectric sensor, which is installed above each output container 8 to detect whether the container is in place and to feed back the position signal to the second transfer component 6, guiding the adsorption clamp 63 to be accurately positioned above the full container, thereby realizing automated transfer.

[0047] In summary, this invention effectively solves the problems of jamming and damage during component loading by using a snap-on detachable loading box 21 with an anti-slip inner wall structure, while also improving the convenience of daily equipment maintenance. A single electrically driven roller 231, combined with an adjustable limit structure 232, enables precise interval transport of individual components, preventing sorting errors at the source. The elastic clamping transfer claw 41, combined with a dual-axis moving module, enables adaptive multi-channel transport of components of different specifications, significantly enhancing the equipment's versatility. The staggered synchronous operation of the dual lifting units 51 enables continuous and uninterrupted switching of container supply, significantly improving sorting efficiency. The detachable and adjustable limit bar 521, along with a vacuum adsorption transfer fixture, ensures the stability of container transport and transfer. The synergistic effect of the pressure sensor 335 and the position sensor achieves fully automated closed-loop control of the sorting and transportation process, fully meeting the high-efficiency, precise, and unmanned production requirements of modern component processing production lines.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope described in the present invention should be included within the scope of protection of the present invention.
