Description

Technical Field

[0001] The present invention relates to the technical field of parts suspension conveying, and in particular to an intelligent suspension conveying system for surface treatment of precision metal parts. Background Art

[0002] A suspended conveyor system is an automated device that enables closed-loop, continuous conveying within a three-dimensional space. Using overhead tracks to support spreader components, it enables the continuous transfer of finished goods within and across workshops. Essentially a spatial logistics network, it can adapt to the material flow needs of various industrial scenarios.

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

[0004] Current mainstream intelligent overhead conveyor systems mostly utilize linear track designs. When multiple consecutive processing stations are required, the system often requires significant length extension, resulting in insufficient horizontal space utilization, high space requirements, and high costs. Reducing space requirements can lead to adjacent stations being too close together, potentially impacting processing results. Summary of the Invention

[0005] The present invention discloses an intelligent suspension conveyor system for surface treatment of precision metal parts. This system aims to address the technical problem that when multiple consecutive processing stations are required, the system often requires significant length extension, resulting in insufficient lateral space utilization, high space requirements, and high costs. Reducing the space requirement can lead to adjacent stations being too close together, which can easily affect the processing results during processing.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] An intelligent suspension conveying system for surface treatment of precision metal parts includes a main rail, and further includes: a plurality of suspension mechanisms, the top ends of the plurality of suspension mechanisms are movably connected to the main rail via sliders at equal intervals; a plurality of translation mechanisms are staggeredly arranged on both sides of the main rail; and a plurality of rotation mechanisms are respectively connected to the plurality of translation mechanisms;

[0008] The guide mechanism is arranged at the tail end of the main rail; the suspension mechanism includes: a support shell, fixedly connected to the outer wall of the bottom end of the slider; a support shaft 1, fixedly connected to the inner walls of the opposite sides of the support shell, and a coil spring is sleeved on its outer wall, one end of the coil spring is fixedly connected to the circumferential outer wall of the support shaft 1; a hollow winding shaft, movably sleeved on the outside of the support shaft 1, and the coil spring is located in the hollow winding shaft, and the other end of the coil spring is fixedly connected to the circumferential inner wall of the hollow winding shaft; a pull rope is wound around the hollow winding shaft, one end of which is rotatably connected to the I-shaped bracket, and the bottom end of the I-shaped bracket is fixedly connected to the hanging bracket;

[0009] The translation mechanism includes: an electric linear guide rail, which is movably connected to a slider 2 inside; a connecting frame, fixedly connected to the outer wall of one side of the slider 2, and having two sets of sleeves fixedly connected to the inner walls of the two opposite sides; two support shafts 2, each of which has two ends located in the two sleeves of each group, and a torsion spring fixedly connected between the outer wall of the support shaft 2 and the inner wall of the sleeve; a hook-shaped splint, fixedly connected to the outer wall of one of the support shafts 2, and having an outer wall movably fitted to the inner wall of one side of the electric linear guide rail; a U-shaped splint, fixedly connected to the outer wall of the other support shaft 2 The outer wall is movably fitted on the inner wall of one side of the electric linear guide; the clamping pad is fixedly fitted on the inner walls of the hook-shaped splint and the U-shaped splint respectively; the guide plate 2 is fixedly connected to one end of the electric linear guide; the guide plate 1 is movably connected to one end of the electric linear guide and is symmetrically arranged with the guide plate 2; the clamping frame is fixedly connected to the guide plate 1, and one side of the outer wall is fixedly connected to a hydraulic rod, and the hydraulic cylinder 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 clamping frame is movably clamped in the limiting groove.

[0010] By setting up a suspension mechanism and a translation mechanism, the suspension mechanism stops moving when it moves to one side of the translation mechanism, and the guide plate is pushed forward by extending the hydraulic rod in the translation mechanism, so that the hook-shaped splint is attached to one side of the work-type bracket, pulling the work-type bracket to move in the direction of the translation mechanism. As the slider 2 continues to move inward, the U-shaped splint and the hook-shaped splint compress the clamping pad to clamp the circumferential outer wall of the work-type bracket, thereby realizing the linkage between the suspension mechanism and the translation mechanism, driving the metal parts to move to both sides to the workstation for surface processing. This structure can make full use of the positions on both sides of the main rail, avoid the long-distance straight-line conveying path required for traditional unilateral traction, and realize a compact layout. In addition, by extending to both sides, the distance between adjacent workstations can be expanded to avoid the distance being too close affecting the respective processing effects on metal parts.

[0011] In a preferred embodiment, the suspension mechanism further comprises: a guide tube fixedly connected to the inner wall of the bottom end of the support shell, and the inner wall diameter of which decreases from top to bottom, and one end of the pull rope passes through the guide tube; a first mounting plate fixedly connected to the outer wall of the bottom end of the guide tube, and a first magnetic piece fixedly embedded in the inner wall of the bottom end of the mounting plate;

[0012] The suspension mechanism also includes: a second mounting plate, which is fixedly connected to the top outer wall of the I-shaped bracket, and a second magnetic piece is fixedly embedded on the top inner wall thereof, and the first magnetic piece and the second magnetic piece are adsorbed on each other; two horizontal plates, which are respectively fixedly connected to the outer walls on both sides of the hollow winding shaft, and the two ends of the support shaft one pass through the center positions of the two horizontal plates, and the circumferential outer wall of the support shaft one is movably fitted to the inner wall of the horizontal plate.

[0014] The guiding mechanism also includes two bending guide plates, which are located on one side of the second support frame and are symmetrically arranged. The outer walls of their bottom ends are movably fitted to the inner walls of the bottom ends of the I-shaped brackets, and their heights are gradually decreasing toward the second support frame; two outward-expanding guide plates are symmetrically fixedly connected to the outer sides of the two bending guide plates; and a second column is fixedly connected to the outer walls of the bottom ends of the bending guide plates.

[0015] By providing a guiding mechanism, before unloading, the I-type bracket will generate impact vibration through the guidance of the outward-expanding guide plate as it separates from the bending guide plate, driving the workpiece at the bottom to vibrate synchronously, thereby eliminating residual stress after surface treatment and reducing the risk of deformation in service. The buffer pad can provide a buffering effect on the support shell at the same time as the impact. In addition, based on the setting of the horizontal guide plate and the concave guide plate, it is convenient for unloading parts and can provide continuous limiting during the recovery process of the I-type bracket, reducing the number of impacts and protecting the service life of the device.

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

[0020] By setting up a rotating mechanism and a translation mechanism, when the I-shaped bracket is clamped in the internal position of the electric linear guide, the start of the motor can drive the rotation of the metal parts during the surface treatment process. Compared with the existing structure with a single suspension mechanism that can rotate, the probability of damage of this structure is small, and the maintenance frequency is reduced. At the same time, based on the setting of multiple PFID tags, the I-shaped bracket can be stopped at different positions to change the distance between the I-shaped bracket and the rotating shaft of the support frame, thereby solving the problem of blind angles in processing special-shaped workpieces.

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0038] Support housing 201, fixedly connected to the bottom outer wall of slider 1 6;

[0039] The support shaft 213 is fixedly connected to the inner walls of the support housing 201 on both sides, and the outer wall of the support shaft 213 is sleeved with a coil spring 212, and one end of the coil spring 212 is fixedly connected to the circumferential outer wall of the support shaft 213;

[0040] The hollow winding shaft 210 is movably sleeved on the outside of the support shaft 1 213, and the coil spring 212 is located inside the hollow winding shaft 210, and the other end of the coil spring 212 is fixedly connected to the circumferential inner wall of the hollow winding shaft 210;

[0041] The pull rope 205 is wound around the hollow winding shaft 210, and one end of the pull rope is rotatably connected to the I-shaped bracket 208, and the bottom end of the I-shaped bracket 208 is fixedly connected to the hanging bracket 209;

[0042] The translation mechanism 3 includes:

[0043] The electric linear guide 301 is movably connected to the second slider 306;

[0044] The connecting frame 304 is fixedly connected to the outer wall of one side of the slider 2 306, and two sets of sleeves 305 are fixedly connected to the inner walls on the opposite sides thereof;

[0045] Two second support shafts 307, with both ends of each second support shaft 307 located in the two sleeves 305 of each group, and a torsion spring 308 fixedly connected between the outer wall of the second support shaft 307 and the inner wall of the sleeve 305;

[0046] The hook-shaped clamping plate 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 rail 301;

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

[0048] The clamping pad 309 is fixedly attached to the inner wall of the hook-shaped clamping plate 311 and the U-shaped clamping plate 310 respectively;

[0049] The second guide plate 315 is fixedly connected to one end of the electric linear guide rail 301;

[0050] The guide plate 1 314 is movably connected to one end of the electric linear guide rail 301 and is symmetrically arranged with the guide plate 2 315. When the suspension mechanism 2 moves to one side of the translation mechanism 3, it stops moving. At this time, the U-shaped splint 310 and the hook-shaped splint 311 in the translation mechanism 3 are tilted outward and fit against the outer ends of the guide plate 1 314 and the guide plate 2 315 under the action of the torsion spring 308. Later, the hydraulic rod 312 is extended, and the limiting groove 316 limits the clamping frame 313, so that the guide plate 1 314 is pushed forward and the hook-shaped splint 311 is pushed inward at the same time, so that the hook-shaped splint 311 fits against one side of the I-shaped bracket 208 and is moved by the electric When the linear guide 301 drives the slider 2 306 to move inward, the I-shaped bracket 208 is pulled toward 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 clamping plate 310 and the hook-shaped clamping plate 311 fit against the inner wall of the electric linear guide 301, driving the two to move inward and compressing the clamping pad 309 to clamp the circumferential outer wall of the I-shaped bracket 208, thereby realizing the linkage between the suspension mechanism 2 and the translation mechanism 3, driving the metal parts to move to the workstation on both sides for surface processing, and stabilizing the position of the metal parts for convenient processing;

[0052] The limiting groove 316 is fixedly connected to the outer wall of the electric linear guide 301, and the clamping frame 313 is movably clamped in the limiting groove 316. This structure can set the processing stations on both sides of the main rail 1, fully utilizing the positions on both sides of the main rail 1, and fully utilizing the horizontal space of the stations, avoiding the long-distance straight conveying path required for traditional unilateral traction, and realizing a compact layout. In addition, by extending to both sides, the distance between adjacent stations can be expanded, avoiding the problem of too close distance affecting the processing effect of each metal part.

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

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

[0055] The mounting plate 1 203 is fixedly connected to the outer wall of the bottom end of the guide tube 202 , and the inner wall of the bottom end of the mounting plate 1 203 is fixedly inlaid with a magnetic piece 1 204 .

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

[0057] The second mounting plate 207 is fixedly connected to the top outer wall of the I-shaped bracket 208, and the top inner wall thereof is fixedly inlaid with a second magnetic piece 206. The first magnetic piece 204 and the second magnetic piece 206 are attracted to each other. The arrangement of the first magnetic piece 204 and the second magnetic piece 206 can drive the pull rope 205 to rewind under the action of the coil spring 212, and quickly position the I-shaped bracket 208 by adsorption when it is about to contact the bottom end of the guide tube 202. At the same time, it can also ensure the movement stability of the metal parts during the translation process of the slider 1 6 driven by the main rail 1;

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

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

[0060] A plurality of PFID tags 302 are fixedly connected to the top outer wall of the electric linear guide 301;

[0061] The identifier 303 is fixedly connected to the top inner wall of the connecting frame 304 and is located directly above the PFID tag 302. It is used to identify the position information of the PFID tag 302. The setting of multiple PFID tags 302 is used to assist the electric linear guide 301 in limiting the translation of the slider 2 306. When the identifier 303 moves to the top of a single PFID tag 302, the slider 2 306 pauses, thereby realizing that the slider 2 306 stays at multiple points on the electric linear guide 301.

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

[0063] The support frame 1 403 has an inner wall on one side thereof penetrated by a mounting groove, and the electric linear guide rail 301 is fixedly connected to the mounting groove;

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

[0065] The annular slot 409 is provided on an inner wall of one side of the main support 401 , and the first support frame 403 is rotatably engaged in the annular slot 409 .

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

[0067] The gear ring 402 is fixedly connected to the circumferential outer wall of the top of the support frame 1 403. The gear ring 402, the main support 401 and one side of the support frame 1 403 are all provided with a notch;

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

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

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

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

[0072] The synchronous belt 405 is simultaneously sleeved on the two synchronous wheels 404;

[0073] The motor 408 is fixedly connected to the bottom end of one of the gears 406 and is fixedly installed on the outer wall of the bottom end of one of the bearing seats 407. When the I-shaped bracket 208 is clamped in the internal position of the electric linear guide 301, the two gears 406 are driven to rotate in the same direction and frequency through the start of the motor 408 and the linkage of the synchronous wheel 404 and the synchronous belt 405. Through the setting of the two gears 406, even if one of them coincides with the notch, the other can ensure the normal rotation of the support frame 1 403 in the main bracket 401. Under this structure, the surface treatment can be guaranteed. The self-rotation of metal parts during the process makes it convenient to process their surfaces. Compared with the existing structure with a single self-rotating suspension mechanism 2, the damage probability of this structure is small, and the maintenance frequency is reduced. At the same time, based on the setting of multiple PFID tags 302, the identification and positioning of the identifier 303 are used to make the I-shaped bracket 208 stop at different positions to change the distance between the I-shaped bracket 208 and the rotating axis of the support frame 403, and change the rotation mode of the I-shaped bracket 208, so as to avoid the spray tool always acting vertically on the uncovered area under the same rotation mode, and solve the problem of processing dead angles of special-shaped workpieces.

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

[0075] The second support frame 504 is fixed on the ground;

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

[0077] The two buffer pads 509 are fixedly attached to the outer walls of the opposite sides of the two side support plates 508, and are movably attached to the outer wall of the support shell 201. When a collision occurs, the support shell 201 just moves between the two buffer pads 509, which can provide a buffering effect for the support shell 201 during the collision, thereby avoiding affecting the linkage between the slider 6 and the main rail 1 under repeated collisions.

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

[0079] Two bending guide plates 502 are located on one side of the second support frame 504 and are symmetrically arranged. The outer walls of the bottom ends thereof are movably fitted to the inner walls of the bottom ends of the I-shaped bracket 208, and the heights thereof are gradually reduced toward the second support frame 504.

[0080] The two outward expansion guide plates 501 are symmetrically fixedly connected to the outside of the two bending guide plates 502. Based on the setting of the coil spring 212, a certain resilience can be given to the stretched pull rope 205. After the surface processing of the part is completed and before cutting, the bending guide plate 502 is pressed on the inner wall of the bottom end of the I-shaped bracket 208 through the guidance of the outward expansion guide plate 501, and the pull rope 205 is stretched to drive the I-shaped bracket 208 to move downward steadily. As the I-shaped bracket 208 separates from the bending guide plate 502, under the rebound action of the coil spring 212, the I-shaped bracket 208 will generate impact vibration, driving the bottom workpiece to vibrate synchronously, thereby eliminating the residual stress after surface treatment and reducing the risk of deformation in service.

[0081] The second column 503 is fixedly connected to the outer wall of the bottom end of the bending guide plate 502 .

[0082] When the cam 314 is in the upright position, the cam 315 is in the upright position, and the cam 316 is in the upright position, so that the cam 316 can move in the upright position, thereby preventing the cam 316 from sliding off and the cam 316 from sliding off. The clamping pad 309 clamps the circumferential outer wall of the I-type bracket 208, thereby realizing the linkage between the suspension mechanism 2 and the translation mechanism 3, driving the metal parts to move to the workstations on both sides for surface processing, and stabilizing the position of the metal parts for convenient processing. This structure can set the processing stations on both sides of the main rail 1, making full use of the positions on both sides of the main rail 1, and making full use of the horizontal space of the workstations, avoiding the long-distance straight-line conveying path required for traditional unilateral traction, and realizing a compact layout. In addition, by extending to both sides, the distance between adjacent workstations can be expanded, avoiding the distance being too close to affect the processing effect of each metal part. After the processing is completed, the I-type bracket 208 is pushed out. At this time, the rebound force of the coil spring 212 can assist the I-type bracket 208 to return to its position. Under the withdrawal of the hydraulic rod 312, the hook-type clamp 311 tilts, and the suspension mechanism 2 can smoothly move forward under the guidance of the main rail 1.

[0083] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
