Description

Technical Field

[0001] The present invention relates to the technical field of suspended conveying equipment, in particular to a suspended conveyor for spraying and anti-corrosion of metal enclosures. Background Art

[0002] Suspension conveyors are a commonly used continuous conveying equipment. They are mainly composed of traction chains, slides, slings, overhead tracks, drive units, tensioning devices, and safety devices. Suspension conveyors suspend the load-bearing parts in the air through hooks and transfer the items through the movement of the traction parts. This enables automatic product transportation, greatly reducing the labor cost required to transfer products. While conveying, they can also perform various process operations, such as material loading, surface treatment, painting, drying, cooling, and finished product unloading.

[0003] When using a suspended conveyor to transport enclosures for processing, traditional spraying work is mostly done manually by using a handheld spray gun to spray the parts hanging on the hook. During spraying, the parts need to be manually moved to rotate the hanger to achieve full spraying. After manual rotation, the hanger will still flip over under the action of inertia and cannot be stable, resulting in uneven spraying, which not only affects the appearance quality of the product, but also reduces the anti-corrosion performance.

[0004] A Chinese patent discloses an automatic hanging device for a hanging conveyor line (publication number CN209241988U). This patented technology uses a positioning clamp to fix the floating hook, preventing the hanger from shaking during hanging, making it easier for the robot gripper to hang the workpiece on the hook.

[0005] However, when the workpiece is hung on the hook for subsequent spraying and other processes, the hook will still swing under the inertia of the conveyor. When spraying, it is necessary to wait until the hanger and the workpiece are stable before proceeding. The work efficiency is low and it is difficult to meet the high requirements of modern industrial production. Summary of the Invention

[0022] Technical effects and advantages of the present invention:

[0023] In the present invention, the two sets of clamping assemblies play an important role when the enclosure body rotates. The clamping assemblies can reduce the shaking of the enclosure body when it rotates, making the enclosure body more stable after rotation. The stable enclosure body can better maintain its position and posture during the spraying process, thereby ensuring the uniformity of the spraying. The stable working environment is also conducive to improving the accuracy and consistency of the spraying, reducing the spraying defects caused by the shaking of the enclosure, and improving the qualified rate of the product.

[0024] In the present invention, the setting of the suspension component effectively ensures the quality of spraying. When the spraying of one side of the enclosure body is completed, the second servo motor is used to drive the relevant components to turn the enclosure body 90 degrees, and switch to the next side for spraying. During the turning and clamping process of the enclosure body, by adjusting the clamping adjustment component, it can be ensured that the clamping component is always clamped on the two sides perpendicular to the spraying surface, and does not contact the surface just sprayed, thereby preventing the powder just sprayed from being rubbed off, further improving the quality of spraying, and making the metal enclosure after spraying have better anti-corrosion performance and appearance effect.

[0025] After the main body of the enclosure is sprayed and before it is flipped, the second servo motor 74 can drive the hook to flip slightly through the first synchronization disk, the first synchronization link and the connecting cam, so that excess powder falls naturally, avoiding excess powder residue affecting the appearance quality of the product, and ensuring that the surface of the enclosure after spraying is more uniform and smooth. During the flipping and clamping process of the enclosure body, the precise control of the servo motor can quickly complete the adjustment and clamping actions, reducing the time and error of manual intervention. Moreover, since the quality of spraying is guaranteed, rework and scrap caused by quality problems are reduced, further improving the overall production efficiency and reducing production costs.

DETAILED DESCRIPTION

[0036] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments.

[0037] Reference Figure 1-9 As shown, the present invention provides a technical solution for a suspended conveyor for spraying and anti-corrosion of metal enclosures:

[0038] A suspended conveyor for spraying and anti-corrosion of metal enclosures, comprising a conveyor body 1, an enclosure body 3, and a spraying room 4. The spraying room 4 is mounted on the conveyor body 1. The conveyor body 1 is provided with multiple sets of connecting hangers 2. The bottom of each set of connecting hangers 2 is rotatably connected to a suspension assembly for suspending the enclosure body 3. The suspension assembly includes a flip assembly 5 rotatably connected to the bottom of the connecting hanger 2. The bottom of the flip assembly 5 is fixedly connected to a connecting assembly 6 for stabilizing the enclosure body 3. The bottom of the connecting assembly 6 is rotatably connected to a hook 8 for suspending the enclosure body 3. The flip assembly 5 is rotatably connected to a clamping adjustment assembly 7 for adjusting the connecting assembly 6.

[0039] Specifically, when in use, first hang the enclosure body 3 to be sprayed on the hook 8, start the conveyor body 1, and drive the connecting hanger 2 to move through the conveyor body 1, so that the connecting hanger 2 drives the suspension assembly to move, and move the enclosure body 3 to the spraying room 4 for spraying;

[0040] When the spraying on one side of the enclosure body 3 is completed, the clamping adjustment component 7 is first started, and the clamping adjustment component 7 drives the hook 8 to flip once, so that the hook 8 drives the enclosure body 3 to flip, so that the excess powder on the enclosure body 3 falls off. After the hook 8 flips over, the clamping adjustment component 7 drives the connecting component 6 to start, and the connecting component 6 clamps both sides of the enclosure body 3 to stabilize the enclosure body 3 and no longer shake. At the same time, the connecting hanger 2 drives the flipping component 5 to rotate, so that the suspension component rotates 90 degrees, so that the other side of the enclosure body 3 is rotated to the spraying position, ready for a new round of spraying work;

[0041] When the enclosure body 3 is rotated into place, the clamping adjustment component 7 is controlled to start again, so that the clamping adjustment component 7 drives the connecting component 6 to open in the opposite direction, and no longer clamps the enclosure body 3, and the enclosure body 3 can be sprayed again. When the spraying is completed, the above work is repeated again until the four surfaces of the enclosure body 3 are sprayed. Then the conveyor body 1 is started to drive the connecting hanger 2 and the suspension component to be moved out of the spraying room 4.

[0042] In this embodiment: the connecting sling 2 includes a pulley 21 and a connecting block 22, the pulley 21 slides on the conveyor body 1, the connecting block 22 is fixedly connected to the bottom of the pulley 21, the connecting block 22 is fixedly connected to the driving motor, and the output end of the driving motor is fixed to the flip box 51 through a coupling, the flip assembly 5 includes a flip box 51, the flip box 51 is rotatably connected to the bottom of the connecting sling 2, the connecting assembly 6 includes a fixed box 61, the fixed box 61 is fixedly connected to the bottom of the flip box 51, the hook 8 is rotatably connected to the bottom of the fixed box 61, and two sets of clamping assemblies are also provided on the fixed box 61, the flip box A fixed plate 52 is fixedly connected to 51, and a clamping adjustment component 7 is arranged above the fixed plate 52. A plurality of limit slots 53 are provided on the fixed plate 52. A synchronization rod 54 is slidably connected to each limit slot 53. The bottoms of the plurality of synchronization rods 54 pass through the flip box 51 and the fixed box 61 and extend into the fixed box 61. The extended ends of the plurality of synchronization rods 54 are respectively connected to adjacent clamping components. The tops of the plurality of synchronization rods 54 extend to the clamping adjustment component 7. A pressure spring 55 is also fixedly connected to each limit slot 53. The other ends of the pressure springs 55 are respectively fixed to adjacent synchronization rods 54.

[0043] Specifically, when in use, after the enclosure body 3 is hung on the hook 8, the conveyor body 1 is started, and the conveyor body 1 drives the pulley 21 to move through the chain (the movement process can be easily achieved by existing technical means and will not be described in detail here), and the pulley 21 drives the turning box 51 and the fixed box 61 to move simultaneously through the connecting block 22, thereby moving the enclosure body 3 into the spraying room 4;

[0044] After the enclosure body 3 is moved into position, the spraying room 4 is started to perform the spraying operation. After the spraying on one side of the enclosure body 3 is completed, the clamping adjustment component 7 is started, and the clamping components on the fixed box 61 are driven by the clamping adjustment component 7 to start, clamping both sides of the enclosure body 3. When the clamping components are in place, the driving motor in the connecting block 22 is started, and the driving motor drives the flip box 51 and the fixed box 61 to rotate 90 degrees, so that the next side is rotated to the spraying position;

[0045] When the rotation is in place, the clamping adjustment component 7 is started to rotate in the opposite direction, so that the clamping adjustment component 7 drives the clamping component on the fixed box 61 to loosen the enclosure body 3, thereby preventing the clamping component from blocking the enclosure body 3 during spraying, resulting in incomplete spraying;

[0046] After the spraying is completed, the above steps are repeated again to adjust the enclosure body 3 so that each surface of the enclosure body 3 is sprayed.

[0047] In this embodiment: two groups of clamping assemblies are also provided on the fixed box 61, and each group of clamping assemblies includes two clamping frames 65, and the two clamping frames 65 in the same group are symmetrically arranged on both sides of the fixed box 61, and the two clamping frames 65 in the same group are rotatably connected to the outer walls of the two sides of the fixed box 61 through a rotating shaft, and the bottom of each clamping frame 65 is hinged with a clamping plate 66, and each clamping plate 66 is fixedly connected to a buffer pad on the side close to the enclosure body 3. A plurality of groups of synchronization grooves 62 are also provided on the fixed box 61, and the bottoms of a plurality of synchronization rods 54 extend to adjacent synchronization grooves 62. A plurality of push rods 63 are also slidably connected to the fixed box 61, and the ends of the plurality of push rods 63 close to the interior of the fixed box 61 are fixedly connected to an L-shaped connecting rod 64, and the top of each L-shaped connecting rod 64 is fixed to the extended end of the synchronization rod 54, and the ends of the plurality of push rods 63 away from the fixed box 61 are slidably connected to the adjacent L-shaped connecting rods 64;

[0048] Specifically, when the spraying is completed, the clamping and adjusting assembly 7 is activated. The clamping and adjusting assembly 7 first pushes the two synchronization rods 54 located on both sides of the spraying surface of the enclosure body 3 to slide in the limit groove 53, so that the two synchronization rods 54 drive one set of clamping assemblies to start and clamp both sides of the enclosure body 3. At this time, the other set of clamping assemblies remains stationary and does not contact the enclosure body 3.

[0049] When two of the synchronization rods 54 move toward each other, the bottoms of the two synchronization rods 54 drive the push rods 63 to slide toward the fixed box 61 through the L-shaped connecting rod 64, so that the push rods 63 pull the adjacent clamping frames 65 to flip toward the fixed box 61 until the two clamping plates 66 at the bottom of the clamping frames 65 contact the two sides of the enclosure body 3 and stabilize the enclosure body 3;

[0050] When the enclosure body 3 is clamped by the two clamping plates 66, the driving motor in the connecting block 22 drives the flip box 51 and the fixed box 61 to rotate 90 degrees through the driving motor, so that the lower side is rotated to the spraying position;

[0051] When it is rotated into place, the clamping adjustment component 7 is started to rotate in the opposite direction, so that the clamping adjustment component 7 drives the two synchronization rods 54 to slide in the limit groove 53 in the direction away from each other, so that the two synchronization rods 54 push the adjacent push rods 63 to extend outward, and the push rods 63 push the clamping frame 65 to flip outward and open, and no longer clamps the enclosure body 3, so as to avoid the clamping component blocking the enclosure body 3 during spraying, resulting in incomplete spraying.

[0052] In this embodiment: the clamping adjustment assembly 7 includes a first adjusting gear 71, the first adjusting gear 71 is rotatably connected to the top of the fixed disk 52, and a first servo motor 72 is also fixedly connected to the flip box 51, and the output end of the first servo motor 72 is fixedly connected to the driving gear 73 through a coupling, and the driving gear 73 is located on one side of the first adjusting gear 71, and the driving gear 73 is meshed with the first adjusting gear 71, and the first adjusting gear 71 is also rotatably connected to the side close to the fixed disk 52 with multiple groups of limit plates 75 and second synchronous disks 78, and one end of each group of limit plates 75 close to the second synchronous disk 78 is rotatably connected to the eccentric position on the second synchronous disk 78, and the other end of each group of limit plates 75 is rotatably connected to the second synchronous disk 78 through a rotating shaft. On the first adjusting gear 71, each set of limit plates 75 is provided with a sliding groove on the side close to the fixed plate 52, and the tops of the multiple synchronization rods 54 are slidably connected to the sliding grooves of the adjacent limit plates 75. The first adjusting gear 71 is also rotatably connected to the side close to the fixed plate 52 with a second adjusting gear 76. The second adjusting gear 76 is rotatably connected to a plurality of second synchronization links 77. The other ends of the plurality of second synchronization links 77 are all rotatably connected to the adjacent second synchronization plates 78, and the two adjacent second synchronization links 77 are symmetrically arranged. A second servo motor 74 is also provided on the side of the first adjusting gear 71 away from the fixed plate 52. The output end of the second servo motor 74 passes through the first adjusting gear 71 and is fixed to the second adjusting gear 76.

[0053] Specifically, when in use, when the spraying work on one side is completed, the second servo motor 74 is first started, so that the second servo motor 74 drives the second adjusting gear 76 to rotate. When the second adjusting gear 76 rotates, the second adjusting gear 76 simultaneously drives multiple second synchronous connecting rods 77 to move, and the two second synchronous connecting rods 77 connected to one group of clamping assemblies will push the adjacent second synchronous disks 78 to rotate in the opposite direction of the second adjusting gear 76. The two second synchronous connecting rods 77 connected to the other group of clamping assemblies will push the other two second synchronous disks 78 to rotate in the same direction as the second adjusting gear 76. The two second synchronous disks 78 with the opposite rotation direction of the second adjusting gear 76 simultaneously drive the limiting plates 75 thereon to flip toward the direction close to the second adjusting gear 76. The other two second synchronous disks 78 drive the two limiting plates 75 thereon to move in the direction away from the second adjusting gear 76 and move to the same center as the second adjusting gear 76.

[0054] When the adjustment is completed, the second servo motor 74 is turned off and the first servo motor 72 is started. The first servo motor 72 drives the driving gear 73 to rotate, and the driving gear 73 drives the first adjusting gear 71 to rotate. When the first adjusting gear 71 rotates, the two limiting plates 75 are flipped toward the direction close to the second adjusting gear 76. Due to the change in trajectory, the two synchronization rods 54 thereon are pushed to slide in the limiting grooves 53, thereby driving the two sets of clamping components to start and clamp the enclosure body 3;

[0055] When the enclosure body 3 is flipped into place, the first servo motor 72 is started in the reverse direction, so that the first servo motor 72 drives the driving gear 73 to rotate in the reverse direction, and the first adjusting gear 71 rotates in the reverse direction. When the first adjusting gear 71 rotates in the reverse direction, it drives the two synchronization rods 54 to move outward, so that the clamping assembly is opened and no longer fixes the enclosure body 3;

[0056] When it is necessary to clamp the enclosure body 3 again, the second servo motor 74 is started again, so that the second servo motor 74 drives the two limit plates 75 concentric with the second adjusting gear 76 to flip in the direction close to the second adjusting gear 76, and pushes the other two limit plates 75 to flip to a position concentric with the second adjusting gear 76. At this time, the first servo motor 72 is started again, and when the driving gear 73 drives the first adjusting gear 71 to rotate, the above movement is repeated again, so that the clamping assembly clamps the enclosure body 3, and drives the fixing box 61 and the enclosure body 3 to rotate through the flip box 51;

[0057] By setting up two groups of clamping components, during use, when the enclosure body 3 is clamped and rotated, the clamping adjustment component 7 can be adjusted to ensure that the clamping components are always clamped on the two side surfaces perpendicular to the spraying surface, without contacting the surface just sprayed, thereby avoiding rubbing off the just sprayed powder. At the same time, the clamping components set up can reduce the shaking of the enclosure body 3 when the enclosure body 3 is rotated, making the enclosure body 3 more stable after rotation, thereby ensuring the uniformity of spraying and improving the efficiency of spraying.

[0058] In this embodiment: the first adjusting gear 71 is also rotatably connected to the side of the fixed disk 52, and the synchronizing gear 79 is meshed with the second adjusting gear 76. The synchronizing gear 79 is fixedly connected to the side of the fixed disk 52, and the end of the driving rod away from the synchronizing gear 79 passes through the fixed disk 52, the flip box 51 and the fixed box 61 in sequence and extends into the fixed box 61. The inner wall of the fixed box 61 near the bottom is also rotatably connected to the first synchronizing disk 67. The top of the first synchronizing disk 67 is fixed to the extended end of the driving rod. The bottom of the first synchronizing disk 67 is hinged with a first synchronizing link 68. The other end of the first synchronizing link 68 is hinged with a connecting cam 69. The end of the connecting cam 69 away from the first synchronizing link 68 is fixed to the hook 8 at the bottom of the fixed box 61.

[0059] Specifically, when the spraying work is completed, the second servo motor 74 starts to drive the second adjusting gear 76 to rotate, and the second adjusting gear 76 simultaneously drives the synchronous gear 79 to rotate, and the synchronous gear 79 drives the first synchronous disk 67 to rotate. The first synchronous disk 67 pulls the connecting cam 69 to flip through the first synchronous link 68, so that the other end of the connecting cam 69 drives the hook 8 to flip, and the hook 8 drives the enclosure body 3 to flip. By flipping the enclosure body 3 once, the excess powder on the enclosure body 3 falls off to prevent excess powder from affecting the appearance quality of the product.

[0060] In order to better understand the present invention, the specific implementation process is given below:

[0061] When in use, first hang the enclosure body 3 to be sprayed on the hook 8, start the conveyor body 1, and drive the connecting hanger 2 to move through the conveyor body 1, so that the connecting hanger 2 drives the suspension assembly to move, and move the enclosure body 3 to the spraying room 4 for spraying;

[0062] When the spraying on one side of the enclosure body 3 is completed, the second servo motor 74 is first started to make the second servo motor 74 drive the second adjusting gear 76 to rotate. When the second adjusting gear 76 rotates, the second adjusting gear 76 simultaneously pushes multiple second synchronous links 77 to move, and the two second synchronous links 77 connected to one group of clamping assemblies will push the adjacent second synchronous disks 78 to rotate in the opposite direction of the second adjusting gear 76. The two second synchronous links 77 connected to the other group of clamping assemblies will push the other two second synchronous disks 78 to rotate in the same direction as the second adjusting gear 76. The two second synchronous disks 78 with the opposite rotation direction of the second adjusting gear 76 simultaneously drive the limiting plates 75 thereon to flip in the direction close to the second adjusting gear 76. The other two second synchronous disks 78 drive the two limiting plates 75 thereon to move in the direction away from the second adjusting gear 76 and move to the same center as the second adjusting gear 76.

[0063] When the second servo motor 74 is started and drives the second adjusting gear 76 to rotate, the second adjusting gear 76 simultaneously drives the synchronous gear 79 to rotate, and the synchronous gear 79 drives the first synchronous disk 67 to rotate. The first synchronous disk 67 pulls the connecting cam 69 through the first synchronous link 68 to flip, so that the other end of the connecting cam 69 drives the hook 8 to flip, and the hook 8 drives the enclosure body 3 to flip. By flipping the enclosure body 3 once, excess powder on the enclosure body 3 falls off, preventing excess powder from affecting the appearance quality of the product;

[0064] When the adjustment is completed, the second servo motor 74 is turned off and the first servo motor 72 is started. The first servo motor 72 drives the driving gear 73 to rotate, and the driving gear 73 drives the first adjusting gear 71 to rotate. When the first adjusting gear 71 rotates, the two limiting plates 75 are flipped toward the direction close to the second adjusting gear 76. Due to the change in trajectory, the two synchronization rods 54 thereon are pushed to slide in the limiting grooves 53, thereby driving the two sets of clamping components to start and clamp the enclosure body 3;

[0065] When the enclosure body 3 is flipped into place, the first servo motor 72 is started in the reverse direction, so that the first servo motor 72 drives the driving gear 73 to rotate in the reverse direction, and the first adjusting gear 71 rotates in the reverse direction. When the first adjusting gear 71 rotates in the reverse direction, it drives the two synchronization rods 54 to move outward, so that the clamping assembly is opened and no longer fixes the enclosure body 3;

[0066] When it is necessary to clamp the enclosure body 3 again, the second servo motor 74 is started again, so that the second servo motor 74 drives the two limit plates 75 concentric with the second adjusting gear 76 to flip in the direction close to the second adjusting gear 76, and pushes the other two limit plates 75 to flip to a position concentric with the second adjusting gear 76. At this time, the first servo motor 72 is started again, and when the driving gear 73 drives the first adjusting gear 71 to rotate, the above movement is repeated again, so that the clamping assembly clamps the enclosure body 3, and drives the fixing box 61 and the enclosure body 3 to rotate through the flip box 51;

[0067] By setting up two groups of clamping components, during use, when the enclosure body 3 is clamped and rotated, the clamping adjustment component 7 can be adjusted to ensure that the clamping components are always clamped on the two side surfaces perpendicular to the spraying surface, without contacting the surface just sprayed, thereby avoiding rubbing off the just sprayed powder. At the same time, the clamping components set up can reduce the shaking of the enclosure body 3 when the enclosure body 3 is rotated, making the enclosure body 3 more stable after rotation, thereby ensuring the uniformity of spraying and improving the efficiency of spraying.
