Description

Technical Field

[0001] This invention relates to the field of suspended conveying technology for parts, and in particular to an intelligent suspended conveying system for surface treatment of precision metal parts. Background Technology

[0002] An overhead conveyor system is an automated device that enables closed-loop continuous transport in three-dimensional space. It uses overhead tracks to carry lifting components, facilitating the continuous transfer of packaged goods within or between workshops. Essentially a spatial logistics network, it can adapt to the material flow needs of various industrial scenarios.

[0003] With the increasing demands for surface treatment quality of precision metal parts in the high-end equipment manufacturing industry, modern production lines often need to integrate multiple processes (such as sandblasting, electroplating, plasma spraying, etc.), and traditional overhead conveyor systems face severe space efficiency challenges.

[0004] Most current mainstream intelligent overhead conveyor systems adopt a linear track design. When multiple continuous processing stations need to be set up, the system often needs to be extended to a large extent, resulting in insufficient lateral space utilization, large space requirements, and high costs. If space requirements need to be reduced, it may lead to adjacent stations being too close together, which can easily affect the processing results during the process. Summary of the Invention

[0005] This invention discloses an intelligent suspended conveying system for the surface treatment of precision metal parts, aiming to solve the technical problem that when multiple continuous processing stations need to be set up, the system often needs to be extended to a great extent, resulting in insufficient lateral space utilization, large space requirements, and high costs. If space requirements need to be reduced, it may lead to the distance between adjacent stations being too close, which may easily affect the processing effect during the process.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An intelligent suspended conveying system for surface treatment of precision metal parts includes a main rail, and further includes: multiple suspension mechanisms, the top ends of which are equidistantly connected to the main rail via sliders; multiple translation mechanisms, which are staggered on both sides of the main rail; and multiple rotation mechanisms, which are connected to the multiple translation mechanisms.

[0008] A guiding mechanism is located at the tail end of the main guide rail; the suspension mechanism includes: a support housing, fixedly connected to the bottom outer wall of the slider one; a support shaft one, fixedly connected to the inner walls of opposite sides of the support housing, and a coil spring is sleeved on its outer wall, one end of the coil spring being fixedly connected to the circumferential outer wall of the support shaft one; a hollow rotating shaft, movably sleeved outside the support shaft one, with the coil spring located inside the hollow rotating shaft, the other end of the coil spring being fixedly connected to the circumferential inner wall of the hollow rotating shaft; a pull rope, wound around the hollow rotating shaft, one end of which is rotatably connected to an I-shaped bracket, and the bottom end of the I-shaped bracket being fixedly connected to a hanger;

[0009] The translation mechanism includes: an electric linear guide rail with a slider two movably connected inside; a connecting frame fixedly connected to one outer wall of the slider two, with two sets of sleeves fixedly connected to its opposite inner walls; two support shafts, each with its two ends located within the two sleeves of each set, and torsion springs fixedly connected between the outer wall of the support shaft and the inner wall of the sleeve; a hook-shaped clamp fixedly connected to the outer wall of one of the support shafts, with its outer wall movably fitting against one inner wall of the electric linear guide rail; and a U-shaped clamp fixedly connected to the other support shaft. The outer wall is movably attached to one side of the inner wall of the electric linear guide; the clamping pads are fixedly attached to the inner walls of the hook-shaped clamp and the U-shaped clamp respectively; the second guide plate is fixedly connected to one end of the electric linear guide; the first guide plate is movably connected to one end of the electric linear guide and is symmetrically arranged with the second guide plate; the snap-fit ​​bracket is fixedly connected to the first guide plate, and a hydraulic rod is fixedly connected to one side of its outer wall, and the hydraulic rod is fixedly connected to the top outer wall of the electric linear guide; the limiting groove is fixedly connected to the outer wall of the electric linear guide, and the snap-fit ​​bracket is movably snapped into the limiting groove.

[0010] By incorporating a suspension mechanism and a translation mechanism, the suspension mechanism stops moving when it reaches one side of the translation mechanism. The translation mechanism, through the extension of a hydraulic rod, pushes the guide plate forward, causing the hook-shaped clamping plate to adhere to one side of the I-shaped bracket, pulling the I-shaped bracket towards the translation mechanism. As the slider continues to move inward, the U-shaped clamping plate and the hook-shaped clamping plate compress the clamping pad, clamping the outer circumference of the I-shaped bracket. This achieves the linkage between the suspension mechanism and the translation mechanism, driving the metal parts to be translated to the workstations for surface processing. This structure fully utilizes the positions on both sides of the main guide rail, avoiding the long straight conveying path required by traditional single-sided traction, achieving a compact layout. Furthermore, extending to both sides increases the distance between adjacent workstations, preventing them from being too close and affecting the processing effect on the metal parts.

[0011] In a preferred embodiment, the suspension mechanism further includes: a guide tube, fixedly connected to the bottom inner wall of the support housing, with its inner wall diameter decreasing from top to bottom, and one end of the pull rope passing through the guide tube; and a mounting plate, fixedly connected to the bottom outer wall of the guide tube, with a magnetic sheet fixedly embedded in the bottom inner wall of the mounting plate.

[0012] The suspension mechanism further includes: a second mounting plate, which is fixedly connected to the top outer wall of the I-shaped bracket, and a second magnetic sheet is fixedly embedded in the inner wall of its top, with the first magnetic sheet and the second magnetic sheet attracting each other; two horizontal plates, which are fixedly connected to the opposite outer walls of the hollow rotating shaft, with the two ends of the first support shaft passing through the center of the two horizontal plates, and the outer circumferential wall of the first support shaft movably fitting against the inner wall of the horizontal plate.

[0013] In a preferred embodiment, the guiding mechanism includes: a second support frame, fixedly placed on the ground; two side support plates, symmetrically fixedly connected to the inner wall of the top of the second support frame; and two buffer pads, respectively fixedly attached to the outer wall of the opposite side of the two side support plates, and movably attached to the outer wall of the support housing.

[0014] The guiding mechanism also includes two bent guide plates located on one side of the support frame two and arranged symmetrically. Their bottom outer walls are movably attached to the bottom inner wall of the I-shaped bracket, and their height decreases towards the support frame two. Two outwardly expanding guide plates are symmetrically fixedly connected to the outside of the two bent guide plates. The second column is fixedly connected to the bottom outer wall of the bent guide plates.

[0015] With a guiding mechanism, before unloading, the I-shaped bracket is guided by the outward-expanding guide plate. As the I-shaped bracket detaches from the bending guide plate, it generates impact vibration, which drives the workpiece at the bottom to vibrate synchronously. This eliminates residual stress after surface treatment and reduces the risk of deformation during service. The buffer pad provides cushioning for the supporting shell during impact. In addition, the horizontal guide plate and the concave guide plate facilitate the unloading of parts and provide continuous limiting during the lifting of the I-shaped bracket, reducing the number of impacts and protecting the service life of the device.

[0016] In a preferred embodiment, the translation mechanism further includes: a plurality of RFID tags fixedly connected to the top outer wall of the electric linear guide; and an identifier fixedly connected to the top inner wall of the connecting frame and located directly above the RFID tags for identifying the location information of the RFID tags.

[0017] The rotating mechanism includes: a support frame 1, with an installation groove through one inner wall, and an electric linear guide rail fixedly connected to the installation groove; a main bracket, fixedly placed on the ground; and an annular slot, provided on one inner wall of the main bracket, and the support frame 1 rotatably engages with the annular slot.

[0018] The rotating mechanism further includes: a gear ring, fixedly connected to the outer circumferential wall of the top of the support frame, with notches provided on one side of the gear ring, the main support, and the support frame; two gears, which simultaneously mesh with the outer wall of the gear ring; and two bearing seats, which are simultaneously fixedly connected to the outer wall of the main support, with the two gears rotatably connected to the two bearing seats respectively.

[0019] The rotating mechanism further includes: two synchronous pulleys, which are respectively fixedly connected to the top outer wall of the two gears; a synchronous belt, which is simultaneously sleeved on the two synchronous pulleys; and a motor, which is fixedly connected to the bottom end of one of the gears and is fixedly installed on the bottom outer wall of one of the bearing seats.

[0020] By incorporating a rotation and translation mechanism, once the I-shaped bracket is clamped within the electric linear guide, the motor can drive the metal parts to rotate during surface treatment. Compared to existing structures with a single rotating suspension mechanism, this structure has a lower probability of damage and reduces maintenance frequency. Furthermore, based on the setting of multiple RFID tags, the I-shaped bracket can be stopped at different positions to change the distance between the I-shaped bracket and the support frame's rotating shaft, thus solving the problem of processing dead angles for irregularly shaped workpieces.

[0021] As described above, an intelligent suspended conveying system for surface treatment of precision metal parts includes a main guide rail, and further includes: multiple suspension mechanisms, the top ends of which are equidistantly connected to the main guide rail via sliders; multiple translation mechanisms, which are staggered on both sides of the main guide rail; multiple rotation mechanisms, which are connected to the translation mechanisms; and a guide mechanism located at the tail end of the main guide rail. The suspension mechanism includes: a support housing, fixedly connected to the bottom outer wall of slider; a support shaft, fixedly connected to the inner walls of opposite sides of the support housing, with a coil spring sleeved on its outer wall, one end of which is fixedly connected to the circumferential outer wall of the support shaft; a hollow rotating shaft, movably sleeved outside the support shaft, with a coil spring located inside the hollow rotating shaft, the other end of which is fixedly connected to the circumferential inner wall of the hollow rotating shaft; and a pull rope wound around the hollow rotating shaft, one end of which is rotatably connected to an I-shaped bracket, the bottom end of which is fixedly connected to a hanger. The translation mechanism includes: an electric linear guide rail, with sliders movably connected inside; and a connecting... The frame is fixedly connected to one side of the outer wall of slider two, and two sets of sleeves are fixedly connected to its opposite inner walls; two support shafts two, each with its two ends located in the two sleeves of each set, and torsion springs are fixedly connected between the outer wall of the support shaft two and the inner wall of the sleeve; a hook-shaped clamp is fixedly connected to the outer wall of one of the support shafts two, and its outer wall movably fits against one side of the inner wall of the electric linear guide; a U-shaped clamp is fixedly connected to the outer wall of the other support shaft two, and its outer wall movably fits against the electric linear guide. The system includes: an inner wall on one side of the linear guide rail; clamping pads, respectively fixedly attached to the inner walls of the hook-shaped clamping plate and the U-shaped clamping plate; a second guide plate, fixedly connected to one end of the electric linear guide rail; a first guide plate, movably connected to one end of the electric linear guide rail and symmetrically arranged with the second guide plate; a snap-fit ​​bracket, fixedly connected to the first guide plate, with a hydraulic rod fixedly connected to one side of its outer wall, the hydraulic rod being fixedly connected to the top outer wall of the electric linear guide rail; and a limiting groove, fixedly connected to the outer wall of the electric linear guide rail, with the snap-fit ​​bracket movably snapped into the limiting groove. The intelligent suspended conveying system for surface treatment of precision metal parts provided by this invention avoids the long linear conveying path required by traditional single-sided traction, achieving a compact layout. Furthermore, it avoids adjacent workstations being too close, thus preventing them from affecting the processing of metal parts. Attached Figure Description

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0031] The intelligent suspended conveying system for surface treatment of precision metal parts disclosed in this invention is mainly applied to scenarios involving the suspended conveying of metal parts.

[0032] Reference Figures 1-5A smart overhead conveying system for surface treatment of precision metal parts, comprising a main guide rail 1, and further comprising:

[0033] Multiple suspension mechanisms 2, the top ends of which are equidistantly connected to the main guide rail 1 via sliders 6;

[0034] Multiple translation mechanisms 3 are staggered on both sides of the main guide rail 1;

[0035] Multiple rotating mechanisms 4 are connected to multiple translational mechanisms 3 respectively;

[0036] The guide mechanism 5 is located at the tail end of the main guide rail 1;

[0037] Suspension mechanism 2 includes:

[0038] The support housing 201 is fixedly connected to the bottom outer wall of the slider 6;

[0039] Support shaft 213 is fixedly connected to the inner walls of opposite sides of the support housing 201, and a disc spring 212 is sleeved on its outer wall. One end of the disc spring 212 is fixedly connected to the outer circumferential wall of support shaft 213.

[0040] A hollow rotating shaft 210 is movably sleeved outside a support shaft 213, and a coil spring 212 is located inside the hollow rotating shaft 210. The other end of the coil spring 212 is fixedly connected to the inner circumference of the hollow rotating shaft 210.

[0041] A pull rope 205 is wound around a hollow shaft 210, and one end of the rope is rotatably connected to an I-shaped bracket 208. The bottom end of the I-shaped bracket 208 is fixedly connected to a hanger 209.

[0042] Translation mechanism 3 includes:

[0043] The electric linear guide 301 has a slider 306 movably connected inside it.

[0044] The connecting frame 304 is fixedly connected to one side of the outer wall of the slider 306, and two sets of sleeves 305 are fixedly connected to its opposite inner walls.

[0045] Two support shafts 307, with both ends of each support shaft 307 located inside the two sleeves 305 of each group, and torsion springs 308 are fixedly connected between the outer wall of the support shaft 307 and the inner wall of the sleeve 305.

[0046] The hook-shaped clamp 311 is fixedly connected to the outer wall of one of the support shafts 307, and its outer wall is movably attached to the inner wall of one side of the electric linear guide 301.

[0047] The U-shaped clamp 310 is fixedly connected to the outer wall of another support shaft 307, and its outer wall is movably attached to the inner wall of one side of the electric linear guide 301.

[0048] Clamping pads 309 are fixedly attached to the inner walls of hook-shaped clamping plate 311 and U-shaped clamping plate 310, respectively;

[0049] Guide plate 2 315 is fixedly connected to one end of electric linear guide rail 301;

[0050] Guide plate 314 is movably connected to one end of the electric linear guide rail 301 and is symmetrically arranged with guide plate 315. When the suspension mechanism 2 moves to one side of the translation mechanism 3, it stops moving. At this time, the U-shaped clamp 310 and the hook-shaped clamp 311 in the translation mechanism 3 are inclined outward and attached to the outer ends of guide plate 314 and guide plate 315 under the action of the torsion spring 308. Then, through the extension of the hydraulic rod 312 and the limiting groove 316 limiting the snap-fit ​​bracket 313, guide plate 314 is pushed forward and hook-shaped clamp 311 is pushed inward, so that hook-shaped clamp 311 is attached to one side of the I-shaped bracket 208 and the electric linear guide rail 315 is moved. When the linear guide rail 301 drives the slider 2 306 to move inward, the I-shaped bracket 208 is pulled to move in the direction of the translation mechanism 3. At this time, the coil spring 212 and the pull rope 205 are stretched synchronously. As the slider 2 306 continues to move inward, the outer walls of the U-shaped clamp 310 and the hook-shaped clamp 311 are attached to the inner wall of the electric linear guide rail 301, driving them to move inward and compressing the clamping pad 309 to clamp the outer circumference of the I-shaped bracket 208. This realizes the linkage between the suspension mechanism 2 and the translation mechanism 3, driving the metal parts to move to both sides to the work station for surface processing, and stabilizing the position of the metal parts for easy processing.

[0051] The clip bracket 313 is fixedly connected to the guide plate 314, and a hydraulic rod 312 is fixedly connected to one of its outer walls. The hydraulic rod 312 is fixedly connected to the top outer wall of the electric linear guide rail 301.

[0052] The limiting groove 316 is fixedly connected to the outer wall of the electric linear guide rail 301, and the snap-fit ​​bracket 313 is movably snapped into the limiting groove 316. This structure can set the processing station on both sides of the main guide rail 1, making full use of the positions on both sides of the main guide rail 1, making full use of the lateral space of the station, avoiding the long straight conveying path required by traditional single-sided traction, and achieving a compact layout. In addition, by extending to both sides, the distance between adjacent stations can be increased, avoiding the effect of the distance being too close on the processing effect of each metal part.

[0053] Reference Figure 3 In a preferred embodiment, the suspension mechanism 2 further includes:

[0054] The guide tube 202 is fixedly connected to the inner wall of the bottom end of the support housing 201, and its inner wall diameter decreases from top to bottom. One end of the pull rope 205 passes through the guide tube 202.

[0055] Mounting plate 203 is fixedly connected to the bottom outer wall of guide tube 202, and magnetic sheet 204 is fixedly embedded in the bottom inner wall of mounting plate 203.

[0056] Reference Figure 4 and Figure 5 In a preferred embodiment, the suspension mechanism 2 further includes:

[0057] Mounting plate 207 is fixedly connected to the top outer wall of I-shaped bracket 208, and magnetic sheet 206 is fixedly embedded in the top inner wall. Magnetic sheet 1 204 and magnetic sheet 206 attract each other. The setting of magnetic sheet 1 204 and magnetic sheet 206 can drive the pull rope 205 to wind back under the action of coil spring 212. When I-shaped bracket 208 is about to contact the bottom end of guide tube 202, it can be quickly positioned by attraction. At the same time, it can also ensure the stability of the movement of metal parts during the translation of the main guide rail 1 driving slider 1 6.

[0058] Two horizontal plates 211 are fixedly connected to the outer walls of the hollow shaft 210 on opposite sides. The two ends of the support shaft 213 pass through the center of the two horizontal plates 211, and the outer circumferential wall of the support shaft 213 is movably attached to the inner wall of the horizontal plate 211.

[0059] Reference Figure 5 In a preferred embodiment, the translation mechanism 3 further includes:

[0060] Multiple RFID tags 302 are fixedly connected to the top outer wall of the electric linear guide rail 301;

[0061] The identifier 303 is fixedly connected to the inner top wall of the connecting frame 304 and is located directly above the RFID tag 302. It is used to identify the position information of the RFID tag 302. The arrangement of multiple RFID tags 302 is used to assist the electric linear guide rail 301 in limiting the translation of the slider 306. When the identifier 303 moves to the top of a single RFID tag 302, the slider 306 stops moving, realizing that the slider 306 stops at multiple points on the electric linear guide rail 301.

[0062] Reference Figure 4 and Figure 6 In a preferred embodiment, the rotating mechanism 4 includes:

[0063] The support frame 403 has a mounting groove through one inner wall, and the electric linear guide rail 301 is fixedly connected in the mounting groove.

[0064] The main support bracket 401 is fixedly placed on the ground;

[0065] An annular groove 409 is provided on one inner wall of the main bracket 401, and the support frame 403 is rotatably engaged in the annular groove 409.

[0066] Reference Figure 4 and Figure 6 In a preferred embodiment, the rotating mechanism 4 further includes:

[0067] The toothed ring 402 is fixedly connected to the outer circumferential wall of the top of the support frame 403. The toothed ring 402, the main bracket 401 and the support frame 403 are all provided with a notch on one side.

[0068] Two gears 406 simultaneously mesh with the outer wall of the gear ring 402;

[0069] Two bearing seats 407 are fixedly connected to the outer wall of the main bracket 401, and two gears 406 are rotatably connected to the two bearing seats 407 respectively.

[0070] Reference Figure 4 and Figure 6 In a preferred embodiment, the rotating mechanism 4 further includes:

[0071] Two synchronous pulleys 404 are fixedly connected to the top outer walls of two gears 406 respectively;

[0072] Synchronous belt 405 is simultaneously fitted onto two synchronous pulleys 404;

[0073] Motor 408 is fixedly connected to the bottom end of one of the gears 406 and is also fixedly mounted on the bottom outer wall of one of the bearing seats 407. When the I-shaped bracket 208 is clamped inside the electric linear guide 301, the starting of motor 408 and the linkage of synchronous pulley 404 and synchronous belt 405 drive the two gears 406 to rotate in the same direction and at the same frequency. Through the arrangement of the two gears 406, even if one coincides with the notch position, the other can ensure the normal rotation of support frame 403 within the main bracket 401. This structure ensures the surface treatment... The rotation of metal parts during the process facilitates surface treatment. Compared to the existing structure of a single rotating suspension mechanism 2, this structure has a lower probability of damage and reduces maintenance frequency. At the same time, based on the setting of multiple RFID tags 302, the I-shaped bracket 208 can be stopped at different positions through the identification and positioning of the reader 303, thereby changing the distance between the I-shaped bracket 208 and the rotating shaft of the support frame 403, changing the rotation mode of the I-shaped bracket 208, and avoiding the spraying tool always acting vertically on the uncovered area under the same rotation mode, thus solving the problem of processing dead angles for irregular workpieces.

[0074] Reference Figure 7 In a preferred embodiment, the guide mechanism 5 includes:

[0075] Support frame 2 (504) is fixedly placed on the ground;

[0076] Two side support plates 508 are symmetrically fixed to the inner top wall of the support frame 504;

[0077] Two buffer pads 509 are fixedly attached to the outer wall of the opposite side of the two side support plates 508, and are movably attached to the outer wall of the support housing 201. When an impact occurs, the support housing 201 moves between the two buffer pads 509, which can provide a buffering effect on the support housing 201 at the same time as the impact, and avoid the repeated impact affecting the linkage between the slider 6 and the main guide rail 1.

[0078] Reference Figure 7 In a preferred embodiment, the guiding mechanism 5 further includes:

[0079] Two bent guide plates 502 are located on one side of the support frame 2 504 and are symmetrically arranged. Their bottom outer walls are movably attached to the bottom inner wall of the I-shaped bracket 208, and their height decreases towards the support frame 2 504.

[0080] Two outwardly expanding guide plates 501 are symmetrically fixed to the outside of two bent guide plates 502. Based on the setting of the coil spring 212, a certain rebound force can be given to the stretched pull rope 205. After the surface of the part is processed and before unloading, the bent guide plate 502 is pressed against the bottom inner wall of the I-shaped bracket 208 by the guidance of the outwardly expanding guide plate 501, and the stretched pull rope 205 drives the I-shaped bracket 208 to move down stably. As the I-shaped bracket 208 is separated from the bent guide plate 502, under the rebound action of the coil spring 212, the I-shaped bracket 208 will generate impact vibration, which will drive the workpiece at the bottom to vibrate synchronously, thereby eliminating the residual stress after surface treatment and reducing the risk of deformation during service.

[0081] Column 2 503 is fixedly connected to the bottom outer wall of the bent guide plate 502.

[0082] Working principle: When the suspension mechanism 2 moves to one side of the translation mechanism 3, it stops moving. At this time, the U-shaped clamp 310 and the hook-shaped clamp 311 in the translation mechanism 3 are tilted outward and attached to the outer ends of the guide plate 1 314 and the guide plate 2 315 under the action of the torsion spring 308. Then, through the extension of the hydraulic rod 312 and the limiting groove 316 limiting the snap-fit ​​bracket 313, the guide plate 1 314 is pushed forward, and at the same time the hook-shaped clamp 311 is pushed inward, so that the hook-shaped clamp 311 is attached to one side of the I-shaped bracket 208. When the electric linear guide rail 301 drives the slider 2 306 to move inward, the I-shaped bracket 208 is pulled to move towards the translation mechanism 3. At this time, the coil spring 212 and the pull rope 205 are stretched synchronously. As the slider 2 306 continues to move inward, the outer walls of the U-shaped clamp 310 and the hook-shaped clamp 311 are attached to the inner wall of the electric linear guide rail 301, driving them to move inward and compress. The clamping pad 309 clamps the outer circumference of the I-shaped bracket 208, thereby realizing the linkage between the suspension mechanism 2 and the translation mechanism 3. This drives the metal parts to be translated to the workstations on both sides for surface processing, and stabilizes the position of the metal parts for easy processing. This structure allows the processing workstations to be set on both sides of the main guide rail 1, making full use of the position on both sides of the main guide rail 1 and making full use of the lateral space of the workstations. This avoids the long straight conveying path required by traditional single-sided traction, achieving a compact layout. In addition, by extending to both sides, the distance between adjacent workstations can be increased, avoiding the impact of the distance being too close on the processing effect of the metal parts. After processing, the I-shaped bracket 208 is pushed out. At this time, the rebound force of the coil spring 212 can assist the I-shaped bracket 208 to return to its position. With the retraction of the hydraulic rod 312, the hook-shaped clamping plate 311 tilts, and the suspension mechanism 2 can smoothly move forward under the guidance of the main guide rail 1.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
