Description

Technical Field

[0001] This invention relates to the field of spinneret assembly technology, specifically to an automatic spinneret assembly line. Background Technology

[0002] The spinneret is a core component of chemical fiber spinning equipment, and its assembly quality directly affects the uniformity and stability of the spun products. Traditional spinneret assembly relies heavily on manual operation, requiring the sequential assembly and testing of components such as the housing feed, sealing ring, metal mesh, gasket, and filter cloth. This presents several problems: manual handling, positioning, and assembly of each component is cumbersome, slow, and difficult to meet the needs of large-scale production; manual operation is susceptible to fatigue and lack of experience, leading to missing, misaligned, or unevenly assembled components, resulting in low product qualification rates; it requires repetitive, single actions over extended periods; and some components (such as the filter cloth) are soft and difficult to handle manually, further increasing the operational difficulty.

Two sets of vertically actuating workpieces 69 are mounted on the assembly frame 1. Each vertically actuating workpiece 69 includes a vertically actuating cylinder 692 fixed to the assembly frame 1. A vertically actuating top plate 691 is fixed to the telescopic end of the vertically actuating cylinder 692. The vertically actuating cylinder 692 can drive the vertically actuating top plate 691 to move up and down, which in turn drives the waste pallet 61 and the workpiece pallet 62 to move up and down. Each set of vertically actuating workpieces 69 consists of two pieces. The up-and-down pushing workpieces 69 respectively push the waste tray 61 and workpiece tray 62 at the end of the spinneret conveying assembly 613 upwards.

[0046] The workpiece positioning seat 53 has a ring structure, and the lower inner side of the workpiece positioning seat 53 is provided with a ring protrusion for positioning the lower end of the spinneret. The workpiece positioning seat 53 positions the spinneret to ensure that the spinneret is in a vertical state during the conveying process.

[0047] An alarm 58 is provided on the upper surface of the detector housing 51. When the spinneret on the workpiece positioning seat 53 is found to be defective, the alarm 58 will issue an alarm.

[0048] The pallet positioning component 68 includes two L-shaped supports 681 arranged on both sides of the pallet conveyor 63. The two L-shaped supports 681 are fixed on both sides of the pallet conveyor 63. A horizontal positioning cylinder 682 is provided on the upper surface of the L-shaped support 681. A positioning top plate 683 is fixed to the output end of the positioning cylinder 682. The positioning top plate 683 can be moved by extending and retracting the positioning cylinder 682.

It is highly adaptable, with the filter cloth feeding component 4 adopting a silicone flexible rubbing plate and corrugated airbag design, which can adapt to the gripping and feeding of soft filter cloth, solving the problem that traditional mechanical grippers are prone to damaging filter cloth. Intelligent sorting combines vision inspection and automatic sorting to remove defective products in real time, preventing unqualified products from flowing into the next process and reducing quality risks.

[0051] In use: This assembly line uses the chain conveyor 7 as the core conveying path, sequentially completing the spinneret housing feeding, sealing ring assembly, metal mesh assembly, gasket assembly, filter cloth assembly, visual inspection, and qualified / defective product sorting and palletizing. The spinneret housing pallet release component 2 releases the stacked housing pallets. The spinneret housing robotic arm and gripper 3 grab the housing and place it on the workpiece positioning seat 53 of the chain conveyor 7. The chain conveyor 7 sequentially conveys the housing to the sealing ring gripping and feeding component 11, the metal mesh gripping and feeding component 10, the gasket gripping and feeding component 9, and the filter cloth feeding component 4. Each feeding component completes the gripping and assembly of the corresponding parts. The assembled spinneret is inspected by the visual inspection component 5 to determine whether it is qualified. The qualified / defective product sorting and palletizing device 6 sorts the qualified / defective products to the workpiece pallet 62 or the waste pallet 61 respectively and completes the palletizing. The collection box 8 at the end of the chain conveyor 7 collects residual workpieces to avoid omission.

[0052] The filter cloth feeding component 4 is used for the automated gripping and feeding of soft filter cloth, solving the problem of difficulty in manual gripping. The horizontal telescopic cylinder 43 drives the simulated finger 45 to move above the barrel-shaped storage bin 46, and the vertical drive cylinder 42 drives the simulated finger 45 to descend. The silicone flexible rubbing plate is inserted between the filter cloths and grips them. Then the horizontal telescopic cylinder 43 moves the filter cloth into the groove 49 of the temporary storage unit, and the sliding seat 48 is moved to the assembly position by the temporary storage moving cylinder 410 to complete the filter cloth feeding.

[0053] The vision inspection component 5 is used to inspect the assembly quality of each component of the spinneret. The chain conveyor 7 transports the spinneret to the bottom of the detector housing 51, and the workpiece positioning seat 53 positions the spinneret. The annular light source 54 and the columnar light source 56 are turned on, and the industrial camera 1 57 and the industrial camera 2 55 capture images simultaneously. The image data is transmitted to the control system and compared with the standard image to determine whether the product is qualified. If it is unqualified, the alarm 58 is activated.

[0054] When the qualified and defective products are sorted by the sorting and palletizing device 6, the signal sent by the vision inspection component 5 to the inside of the sorting and palletizing device 6 is sent. When the pallets are loaded, the workpiece 69 is pushed up and stacked. The pallet separation clamping component 67 separates the bottom pallet. After the pallet positioning component 68 positions it, it is transported to the pallet stacking position by the pallet conveyor 63. When the products are sorted, the visually qualified products are picked up and flipped by the workpiece flipping component 66 and placed into the qualified temporary storage support 611. The unqualified products are directly placed into the defective temporary storage support 611. The robotic arm 615 grabs the products in the temporary storage support 611 and stacks them into the corresponding workpiece pallet 62 or waste pallet 61. The full pallet is supported by the pallet support platform 64 and waits for manual transfer.

[0055] When supporting the waste pallet 61 and the workpiece pallet 62, the workpiece 69 is pushed up and down to move the waste pallet 61 or the workpiece pallet 62 upward. When the waste pallet 61 or the workpiece pallet 62 moves upward, the ear plates on both sides contact the rotating support plate 642, and the rotating support plate 642 rotates upward. The ear plates on both sides of the waste pallet 61 or the workpiece pallet 62 continue to move upward and disengage from the rotating support plate 642. The rotating support plate 642 falls back to a horizontal state due to gravity. The workpiece 69 pushes the waste pallet 61 or the workpiece pallet 62 downward. The ear plates of the waste pallet 61 or the workpiece pallet 62 are supported by the rotating support plate 642. At this time, the waste pallet 61 or the workpiece pallet 62 is disengaged from the pallet conveyor 63. The positioning cylinder 682 can extend and retract to move the positioning top plate 683. The positioning top plate 683 can push the waste pallet 61 or the workpiece pallet 62 to the middle position of the pallet conveyor 63 for stacking.
