Technical Field
[0001] This invention relates to the field of L-shaped grounding bracket processing technology, and particularly to a suspended conveying device for processing L-shaped grounding brackets. Background Technology
[0002] L-shaped grounding brackets, also known as L-shaped grounding supports or grounding terminal blocks, are electrical, lightning protection, and anti-static products. Their core function is to fix and connect grounding wires and grounding bars to achieve reliable grounding and conductivity. The L-shaped body is mainly made of stamped metal. When conveying materials inside the L-shaped grounding bracket, a suspended conveying device is mainly used. The suspended conveying device hangs the materials above for conveying, and the ground can be used for people, vehicles, and equipment, greatly improving the utilization rate of the workshop. In the automated conveying process of L-shaped bodies, due to their small size, magnetic suspension structures are often used to pick up and transfer workpieces. Traditional magnetic suspension devices mostly use continuous power to maintain electromagnetic attraction to ensure that the workpiece remains in an adsorbed state throughout the transfer. However, traditional electromagnetic mechanisms remain energized during non-working periods, such as during unloaded return trips, standby, or when the adsorption head is not aligned with the workpiece, resulting in a large amount of ineffective energy loss. At the same time, long-term continuous power supply can easily cause the electromagnet to heat up, affecting its service life and operational stability. Therefore, a suspended conveying device for L-shaped grounded pedestal processing is needed to solve the above problems. Summary of the Invention
[0003] The purpose of this invention is to provide a suspended conveyor device for processing L-shaped grounding support seats, which solves the problem that existing traditional magnetic suspension conveyors remain energized during non-working periods, such as during unloaded return trips, standby, or movement when the adsorption head is not aligned with the workpiece, resulting in a large amount of ineffective energy loss; at the same time, long-term continuous energization can easily cause the electromagnet to heat up, affecting its service life and operational stability.

[0006] Preferably, an electromagnetic force adsorption head is installed at the bottom of the conductive base, an insulating plate is installed on one side of the electromagnetic force adsorption head, a movable groove is opened inside the insulating plate, a fixed block is installed inside the movable groove, and the top of the fixed block is connected to the bottom of the conductive connecting frame.
[0007] Preferably, a pressing head is installed at the bottom end of the fixing block, a trigger head is installed on one side of the pressing head, a telescopic spring is installed on one side of the trigger head, one side of the telescopic spring is connected to one side of the insulating plate, and the telescopic spring and the trigger head form a telescopic structure.
[0008] Preferably, the electromagnetic force adsorption head has a moving groove inside, a moving block is installed inside the moving groove, a protrusion is installed at the bottom of the moving block, and hinge frames are hinged to both sides of the front end of the moving block, with a clamping block hinged to the bottom of the hinge frame.
[0009] Preferably, the clamping blocks are provided in two sets, and the two sets of clamping blocks are symmetrically distributed on both sides of the bottom end of the electromagnetic force adsorption head.
[0010] Preferably, a support leg is installed at the bottom end of the suspension frame, a workbench is installed at the middle position of the bottom end of the suspension frame, and a positioning seat is installed at the top of the workbench.
[0011] Preferably, the conductive sleeve is fitted onto the outside of the guide post, and the conductive sleeve and the guide post form a sliding guide connection.
[0012] Preferably, the insulating reset spring is provided in multiple sets, and the multiple sets of insulating reset springs are distributed in a ring at the top end of the conductive sleeve.
[0013] Preferably, one end of the guide rod is inserted into the interior of the energized guide rail, and the guide rod and the energized guide rail form a sliding connection.
[0014] The present invention provides a suspended conveyor device for processing L-shaped grounding supports, the advantages of which are: By incorporating a clamping structure and arranging the energized guide rails only within the effective travel range of the workpiece conveyor, the mounting frame is removed from the power supply area during the empty return phase after conveying, resulting in no power input. This effectively cuts off power consumption during the empty period from the source in terms of power supply layout. Compared with traditional fully energized magnetic conveying devices, this significantly reduces overall energy consumption and demonstrates outstanding energy-saving effects. Furthermore, by employing a conductive base surface insulation combined with a multi-stage mechanical linkage triggering conductive method, the conductive circuit is made graded: before the electromagnetic adsorption head is properly aligned with the workpiece, even if the conductive head is in contact with the conductive base and the guide rod is connected to the energized rail, the circuit is still in an open state. Only when the electromagnetic adsorption head is fully aligned with the workpiece can a complete energized circuit be formed, truly realizing "no power without alignment, no power without alignment". This completely avoids ineffective power consumption in non-working states such as movement, standby, and idle travel, further enhancing the energy-saving effect and preventing the electromagnetic adsorption head from overheating due to long-term continuous power supply, which could affect its service life and operational stability. Furthermore, the positioning seat limits the L-shaped grounding bracket, providing a reliable reverse extrusion force to the trigger head, ensuring stable and reliable operation of the triggering structure. It can achieve power-on triggering without relying on the weight or strength of the workpiece itself, and is suitable for L-shaped workpieces that are small in size, light in weight, and easy to move. Furthermore, by adopting a pre-energized method, the electromagnet can be effectively prevented from generating magnetic force prematurely, thus preventing lightweight workpieces from being attracted off-center, tilted, or pulled away from the positioning position due to premature magnetic force. This ensures that the electromagnetic adsorption head can accurately align and adsorb the workpiece every time, improving the success rate of loading and conveying, and reducing workpiece jamming, falling, and other malfunctions.
[0015] Furthermore, while the workpiece is attracted upward by the electromagnetic adsorption head, the squeezing protrusion drives the moving block to move upward, and through the hinge frame, the clamping blocks on both sides automatically close to the middle to clamp the workpiece, forming a dual fixing structure of "electromagnetic adsorption + mechanical clamping". Even if there is a brief vibration or magnetic fluctuation during the conveying process, the workpiece will not loosen or fall off, which greatly improves the stability and safety of the conveying process. When unloading, the conductive sleeve is automatically reset by the insulated reset spring. With the weight of the moving block falling back and the telescopic spring resetting the trigger head, the magnetic force disappears, the clamp opens, and the workpiece falls down synchronously, making the unloading smooth.

[0019] Please see Figures 1-12 The present invention provides a suspended conveying device for processing L-shaped grounding support, comprising a suspension frame 1 and a clamping structure 3; The top of the suspension frame 1 is provided with a drive assembly 2, the inside of the suspension frame 1 is provided with a sprocket 7, the outside of the sprocket 7 is provided with a chain 8, and the bottom of the chain 8 is provided with a clamping structure 3.
[0020] Reference Figures 1-12As shown, the clamping structure 3 includes an energized guide rail 302, which is mounted on one side of the bottom end of the suspension frame 1. A mounting bracket 301 is mounted on the bottom end of the chain 8. An insulating fixing sleeve 3012 is mounted on the bottom end of the mounting bracket 301. A guide post 303 is mounted at the middle position of the bottom end of the mounting bracket 301. A conductive sleeve 305 is mounted on the outer side of the guide post 303.

The guide rod 3010 has one end connected to the rear end of the conductive sleeve 305. An insulating reset spring 304 is installed at the top of the conductive sleeve 305. The top of the insulating reset spring 304 is connected to the bottom end of the mounting bracket 301. The insulating reset spring 304 and the conductive sleeve 305 form a telescopic structure. An electromagnetic force adsorption head 3011 is installed at the bottom of the conductive base 307. An insulating plate 3022 is installed on one side of the electromagnetic force adsorption head 3011. An active groove 3023 is opened inside the insulating plate 3022. A fixing block 3017 is installed inside the active groove 3023. The top of the fixing block 3017 is connected to the bottom end of the conductive connecting bracket 308. A pressing head 3020 is installed at the bottom of the fixed block 3017. A trigger head 3018 is installed on one side of the pressing head 3020. A telescopic spring 3019 is installed on one side of the trigger head 3018. One side of the telescopic spring 3019 is connected to one side of the insulating plate 3022. The telescopic spring 3019 and the trigger head 3018 form a telescopic structure. The electromagnetic force adsorption head 3011 has a moving groove 3016 inside, a moving block 3021 is installed inside the moving groove 3016, a protrusion 3014 is installed at the bottom of the moving block 3021, and a hinge frame 3015 is hinged to both sides of the front end of the moving block 3021, and a clamping block 3013 is hinged to the bottom of the hinge frame 3015. Two sets of clamping blocks 3013 are provided, and the two sets of clamping blocks 3013 are symmetrically distributed on both sides of the bottom end of the electromagnetic force adsorption head 3011. A support leg 6 is installed at the bottom of the suspension frame 1, a worktable 5 is installed at the middle position of the bottom of the suspension frame 1, and a positioning seat 4 is installed at the top of the worktable 5. The conductive sleeve 305 is sleeved on the outside of the guide post 303, and a sliding guide connection is formed between the conductive sleeve 305 and the guide post 303. Multiple sets of insulating reset springs 304 are provided, and the multiple sets of insulating reset springs 304 are arranged in a ring at the top of the conductive sleeve 305; one end of the guide rod 3010 is inserted into the interior of the energized guide rail 302, and the guide rod 3010 and the energized guide rail 302 form a sliding connection.
[0021] When processing and conveying the L-shaped grounding bracket, the L-shaped grounding bracket is placed in the positioning seat 4 at the top of the workbench 5. The positioning seat 4 provides a limiting constraint on the workpiece. After the workpiece is limited, the external power supply starts the motor at the top of the drive assembly 2. The motor drives the sprocket 7 to rotate through the reducer at its bottom. When the sprocket 7 rotates, it drives the chain 8 and the mounting bracket 301 at the bottom to move synchronously. As the mounting bracket 301 moves, the energized guide rail 302 is powered on by the external power supply. When the mounting bracket 301 moves to the area of the energized guide rail 302, under the action of the irregular guide of the energized guide rail 302, one end of the guide rod 3010 is inserted into the energized guide rail 302. Inside the electric guide rail 302, the conductive sleeve 305 moves downward along the outside of the guide post 303 as the mounting frame 301 moves, guiding the conductive sleeve 305. At the same time, the insulating reset spring 304 undergoes elastic deformation. When the guide rod 3010 disengages from the electric guide rail 302, the insulating reset spring 304 can drive the conductive sleeve 305 to reset. When the guide rod 3010 contacts the electric guide rail 302, it can supply power to the conductive sleeve 305. Since the electric guide rail 302 is only arranged in the workpiece conveying stroke range, the mounting frame 301 has no power supply during the empty return stroke after the conveying is completed, thereby reducing the power consumption.
[0022] As the conductive sleeve 305 moves downward, its bottom conductive head 306 comes into contact with the conductive base 307. Since the surface of the conductive base 307 has an insulating layer, the contact between the conductive head 306 and the conductive base 307 does not immediately establish a circuit. After the conductive head 306 and the conductive base 307 are fully in contact, the mounting bracket 301 continues to move until the electromagnetic adsorption head 3011 abuts against one side of the positioning seat 4. Because the positioning seat 4 provides a fixed limit for the workpiece, the workpiece reverses and presses against the trigger head 3018, causing the trigger head 3018 to push the pressing head 3020 to one side. The pressing head 3020 and the bottom of the fixing block 3017 have matching inclined surfaces. When the pressing head 3020 moves laterally, it pushes the fixing block 3017... 017 moves upward, and the fixed block 3017 pushes the conductive connecting frame 308 upward, so that the top of the conductive connecting frame 308 moves to the outside of the conductive head 306. At this time, a complete power circuit is formed between the conductive head 306 and the conductive seat 307. This ensures that the electromagnetic adsorption head 3011 is energized only after it is accurately attached and aligned with the workpiece. Even if the guide rod 3010 contacts the energized guide rail 302 when it is not aligned, it will not be energized. This avoids the electromagnetic adsorption head 3011 from wasting power during non-working periods such as movement, standby, and no-load, which significantly saves energy. At the same time, it can prevent the problem of lightweight workpieces being attracted and displaced by magnetic force due to premature energization, which would prevent normal adsorption. This further reduces energy consumption during the conveying process.
[0023] When the conductive base 307 is energized, the electromagnetic adsorption head 3011 generates a magnetic attraction force. The design ensures that the electromagnetic adsorption head 3011 maintains a certain distance from the bottom of the workpiece. When the electromagnetic adsorption head 3011 is energized, it can instantly adsorb the workpiece upwards, making the workpiece adhere to the bottom end of the electromagnetic adsorption head 3011. When the workpiece is adsorbed, it presses the protrusion 3014 upwards, thereby pushing the moving block 3021 to move upwards along the moving groove 3016. During the upward movement of the moving block 3021, the hinge frame 3015 drives the two sets of clamping blocks 3013 to close towards the middle. Since the electromagnetic adsorption head 3011 has limit grooves on both sides and the clamping block 3013 has a limit block on one side, the two sets of clamping blocks 3013 can move towards the middle to clamp the two sides of the workpiece, further improving the stability of the workpiece during transportation and preventing the workpiece from falling during the magnetic transportation process. As the mounting bracket 301 continues to move, after it has completed the effective stroke of the energized guide rail 302, the guide rod 3010 disengages from the guiding constraint of the energized guide rail 302. Under the rebound action of the insulating reset spring 304, the conductive sleeve 305 resets, the magnetic force of the electromagnetic adsorption head 3011 disappears, the moving block 3021 falls back under its own weight, the clamping block 3013 opens, and at the same time the trigger head 3018 resets under the action of the telescopic spring 3019. The workpiece then falls down, completing the suspension and conveying operation of the L-shaped grounding bracket, thus completing the suspension and conveying operation of the L-shaped grounding bracket.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
