Description

Technical Field

[0001] This application relates to the technical field of furniture production lines, and in particular to a baby crib assembly line. Background Technology

[0002] In the crib manufacturing industry, assembly lines for folding cribs play a crucial role. The main task of these lines is to efficiently assemble the various components into a complete folding crib, ensuring its quality meets relevant standards.

[0003] Specifically, the assembly process of a folding crib typically involves the following key steps: First, the initial connection of the frame is performed. During this process, a crib cover needs to be fitted into the appropriate positions on the frame to ensure the crib's appearance and comfort. Next, to enhance the structural stability, the joints of the frame need to be reinforced with bolts, which is an important step in ensuring the safety of the crib during use. Subsequently, anti-collision strips are installed around the crib's edges, a step designed to improve the crib's safety and user experience. These anti-collision strips not only effectively prevent injuries to the baby from collisions while playing but also add a touch of warmth and comfort to the crib. After completing the above steps, the finished crib is folded for subsequent packaging. The folding process needs to ensure that all parts of the crib fit tightly to avoid loosening or damage during transportation and use. Finally, the crib is packed into a cardboard box for final shipping and sale. The cardboard box not only provides extra protection but also facilitates the printing of product information and barcodes, making management and tracking easier.

[0004] However, in existing crib assembly lines, the aforementioned steps primarily rely on manual operation. This traditional production method is not only inefficient but also susceptible to human error, leading to inconsistent product quality. Therefore, optimizing the assembly process, improving production efficiency, and ensuring product quality have become pressing issues for the crib manufacturing industry. Summary of the Invention

[0037] The following is in conjunction with the appendix Figure 1 To be continued Figure 7 This application will be described in further detail.

[0038] To increase the efficiency of crib assembly, this application provides a crib assembly line, which includes a pre-assembly station 11, a fixing station 12, a shock-absorbing strip installation station 13, a folding station 14, and a packaging station 15. The stations are connected by conveyor belts, allowing semi-finished products to be transported sequentially between them. The pre-assembly station 11 includes two workbenches. At one workbench, operators inspect and pre-assemble the produced frame. At the other workbench, operators unfold and inspect the crib cover, then insert the cover onto the frame, sometimes requiring disassembly of the frame before insertion into the cover's insertion holes. Several frame connections are tightened. The semi-finished product is then placed on the conveyor belt and sent to the fixing station 12. The fixing station 12 includes a screw feeder and several first robotic arms. The screw feeder is a pneumatic screw feeder, which is prior art and will not be described further here. The first robotic arm is equipped with an automatic screw-fastening machine, which is combined with a screw feeder to form an automatic screw-fastening station, saving labor costs and speeding up processing efficiency. Depending on the parts of the crib that need reinforcement, the fixing station 12 can be divided into two stations, one for fastening the upper bolts and the other for fastening the lower bolts. Furthermore, a strapping and labeling station can be set up after the fixing station 12. The reinforced and labeled semi-finished product is fed into the anti-collision strip installation station 13 to install anti-collision strips around the crib's edges. This step aims to improve the crib's safety and user experience. The anti-collision strips not only effectively prevent injuries to the baby during play but also add warmth and comfort to the crib. After completing the above steps, the finished crib is folded for subsequent packaging. The folding process must ensure that all parts of the crib fit tightly to avoid loosening or damage during transportation and use. The next step involves setting up a packing station 15, which includes a station for rolling up the folded crib and its matching bed board together, and for placing the crib and bed board from the previous station into a packing bag and zipping it up. This step is not only to protect the crib from external environmental damage but also to facilitate subsequent transportation and storage. Furthermore, to improve moisture and dust protection, a PE bag is placed over the packing bag at packing station 15. The sealing performance of the PE bag effectively isolates air and moisture, thus extending the crib's lifespan. Finally, the PE bag containing the crib is placed into a cardboard box for final transportation and sale. The cardboard box not only provides additional protection but also facilitates printing product information and barcodes, making management and tracking easier. Packing station 15 includes a carton opener, a carton sealer, and a stacker, which are existing technologies and will not be described in detail here.

[0039] Furthermore, to improve the efficiency of fabric strip installation at the anti-collision strip installation station 13, this embodiment also provides an automated anti-collision strip installation scheme. It is worth noting that this embodiment is applicable to rectangular cribs, with fabric openings along the four edges of the crib's interior space within the crib cover for inserting fabric strips. The anti-collision strips can be inserted along their length into the crib cover through these openings, forming a perimeter around the crib. Specifically, the anti-collision strip installation station 13 includes an installation table, a second robotic arm 2, a base 315, an insertion strip assembly 3, and a bag opening assembly 5. The anti-collision strip installation station 13 also includes a strip feeding assembly 7. A conveyor belt transports the semi-finished product from the previous station to the installation table. The anti-collision strips are then installed on the semi-finished product on the installation table. The strip feeding assembly 7 is located on one side of the installation table for conveying the anti-collision strips. The second robotic arm 2 is located on one side of the installation table. The base 315 is connected to the working end of the second robotic arm 2. The insert assembly 3 is connected to the second robotic arm 2 via the base 315. The insert assembly 3 receives the anti-collision strip and can move with the second robotic arm 2 to deliver the anti-collision strip into the crib. The bag opening assembly 5 is disposed on the base 315 and is used to open the crib cover bag to expose the opening for inserting the anti-collision strip.

[0040] Specifically, the vertical state of the anti-collision strip is defined as its position when inserted into the bed sheet. In the vertical state, the longest side of the anti-collision strip is horizontal, the short side is along the direction of gravity, and the thickness is on the same plane as the longest side. The strip feeding assembly 7 includes a strip feeding groove tube 71, a steering seat 72, and several conveying rollers 73. The strip feeding assembly 7 is mounted on a table to support it at a suitable height. The strip feeding groove tube 71 is connected to the steering seat 72. The strip feeding groove tube 71 has a U-shaped cross-section structure, allowing several anti-collision strips to enter the strip feeding groove tube 71 along the long side and remain vertical. Several conveying rollers 73 are rotatably connected to the bottom of the strip feeding groove tube 71 at linear intervals to convey the anti-collision strips. The conveying rollers 73 are horizontally positioned and simultaneously driven to rotate by a motor. Furthermore, a quarter-circle arc-shaped steering groove 721 is formed inside the steering seat 72. The two ends and the top of the steering groove 721 penetrate the steering seat 72. One end of the turning groove 721 is connected to the end of the feed groove tube 71. The other end of the turning groove 721 extends outward and faces the direction parallel to the conveyor belt. The anti-collision strip is fed into the turning groove 721 along its length through the feed groove tube 71 and is in a vertical position.

[0041] Furthermore, the strip feeding assembly 7 also includes a steering roller 74 and a stabilizing roller 75. The steering seat 72 has a groove 722 along the radial direction of the steering groove 721. The steering roller 74 is rotatably connected to the groove 722. The steering roller 74 is vertically disposed in the groove 722, with a portion of the steering roller 74 extending into the steering groove 721 through the groove 722. When the anti-collision strip is fed into the steering groove 721 via the strip feeding tube 71 and abuts against the steering roller 74, the distance between the steering roller 74 and the inner wall of the steering groove 721 is set to be less than the thickness of the anti-collision strip, allowing the anti-collision strip to slide under the frictional force of the steering roller 74. The reversing seat is provided with a first driving member for driving the steering roller 74 to rotate. The first driving member is a motor. Two stabilizing rollers 75 are provided, and the two stabilizing rollers 75 are spaced apart at the outlet of the turning groove 721, located inside the inner wall of the turning groove 721. Similarly, each stabilizing roller 75 partially penetrates the turning groove 721, and the minimum interval between the two stabilizing rollers 75 is less than the width of the turning groove 721. The arrangement of the stabilizing rollers 75 ensures that the end of the anti-collision strip is stabilized when it moves out of the turning groove 721, preventing deviation.

[0042] Furthermore, the insert assembly 3 is connected to the second robotic arm 2 via the base 315. The insert assembly 3 can be driven by the second robotic arm 2 to move to a position corresponding to the feeding assembly 7, allowing the anti-collision strip to be fed into the insert assembly 3 through the turning groove 721 for anti-collision strip operation. The insert assembly 3 includes a reversing seat 31, and a power roller 32 and several feeding rollers 33 vertically arranged in the reversing seat 31. It is worth noting that the reversing seat 31 can rotate with the second robotic arm 2. In this embodiment, the reversing seat 31 is in a horizontal state, i.e., capable of receiving the vertical anti-collision strip, which is the initial state. The following descriptions are all in the initial state. The reversing seat 31 has a docking groove 311, a reversing groove 312, and a feeding groove 313 connected sequentially. The base 315 is located at the end of the reversing seat 31 away from the outlet of the feeding groove 313. The docking groove 311, the reversing groove 312, and the feeding groove 313 all extend upwards. The docking groove 311 is parallel to the feed groove 313, and the length direction of the docking groove 311 corresponds to the outlet direction of the turning groove 721. The reversing groove 312 is a half-arc shape, with its two ends connected to one end of the docking groove 311 and the feed groove 313, respectively. The power roller 32 is vertically rotatably connected to the reversing groove 312 at its concentric point, and part of the power roller 32 penetrates into the reversing groove 312. The distance between the outer wall of the power roller 32 and the inner wall of the reversing groove 312 is slightly less than the thickness of the anti-collision strip, i.e., the two are interference fit. The power roller 32 rotates, thereby using friction to drive the anti-collision strip to move. Several feed rollers 33 are rotatably connected to the reversing seat 31 along a straight line. Part of the feed rollers 33 penetrate into the feed groove 313. The distance between the outer wall of the feed roller 33 and the inner wall of the feed groove 313 is slightly less than the thickness of the anti-collision strip. A docking notch 34 is provided on the outer side of the reversing seat 31. The docking notch 34 communicates with the docking groove 311. After the reversing seat 31 can move, the docking groove 311 connects with the steering groove 721. The shape of the docking notch 34 corresponds to the shape of the steering seat 72. The reversing seat 31 is provided with a second driving member 321 that drives the power roller 32 to rotate. And a synchronization component 4 that makes several feed rollers 33 rotate together with the power roller 32.

[0043] Furthermore, the second drive component 321 is a motor, and its output shaft is coaxially connected to the power roller 32. The synchronization assembly 4 includes a drive sprocket 41, a driven sprocket 42, and several synchronization sprockets 43. The drive sprocket 41 is coaxially connected to the output shaft of the second drive component 321. A rotating shaft is provided on the central axis of each of the feed rollers 33. Each synchronization sprocket 43 is coaxially connected to its corresponding rotating shaft. The rotating shaft of the feed roller 33 closest to the power roller 32 is coaxially connected to the driven sprocket 42. The driven sprocket 42 is connected to the drive sprocket 41 via a first chain 44. The synchronization sprockets 43 are connected via a second chain 45.

[0044] Furthermore, an extended sheet 314 is provided at the outlet of the feed groove 313. One end of the extended sheet 314 is connected to the reversing seat 31, and the other end extends outward. The extended sheet 314 is flush with the inner wall of the feed groove 313.

[0045] Specifically, the pocket opening assembly 5 includes a support piece 51 and a first control assembly 6. One end of the support piece 51 is connected to the reversing seat 31 via the first control assembly 6, and the support piece 51 is connected to the outer wall of the reversing seat 31 on the side away from the docking groove 311. The other end of the support piece 51 extends away from the reversing seat 31. After one end of the support piece 51 enters the length extension range of the feed groove 313, it tilts and then extends along the length direction of the feed groove 313. The inner wall of the feed groove 313 on the side away from the docking groove 311 is the top, and the inner wall of the feed groove 313 on the side close to the docking groove 311 is the bottom. Initially, the support piece 51 extends from the top of the feed groove 313 across the length range of the feed groove 313 to the bottom of the feed groove 313. At this time, the end of the support piece 51 can be inserted into the pocket opening of the sheet. The first control assembly 6 can control the support piece 51 to translate and leave the length extension range of the feed groove 313. When the support piece 51 is inserted into the bag opening, the first control component 6 controls the support piece 51 to translate, thereby causing the bed cover to deform and form an opening for the insertion of the anti-collision strip. The end of the support piece 51 is arc-shaped to prevent damage to the bed cover when inserted into the bag opening. The first control component 6 includes a base piece 61, a first screw 62, and a guide rod 63. The end of the first screw 62 is connected to a third drive member 621, which is connected to the outer wall of the reversing seat 31. The first screw 62 extends outward along the length direction perpendicular to the feed groove 313. One end of the guide rod 63 is connected to the outer wall of the reversing seat 31, and the guide rod 63 is parallel to the first screw 62. The first screw 62 and the guide rod 63 pass through the base piece 61. The first screw 62 and the base piece 61 are threaded together. The support piece 51 is connected to the base piece 61.

[0046] Furthermore, the support piece 51 includes two separate strips 511. The separate strips 511 are slidably connected to the base piece 61, and the base piece 61 is provided with a protrusion 611. A limiting groove 512 is formed at the end of the separate strip 511. The protrusion 611 is arranged perpendicular to the length direction of the feeding groove 313. The protrusion 611 is slidably connected in the limiting groove 512. The bag opening assembly 5 also includes a second control assembly 8 for controlling the separate strips 511 to move closer or further apart from each other. The second control assembly 8 includes a fourth drive member 831, a bidirectional screw 81, a reversing worm gear 82, and a reversing worm 83. The fourth drive member 831 is disposed on the base piece 61 and is a motor. The output end of the fourth drive member 831 is coaxially connected to the reversing worm 83, driving the reversing worm 83 to rotate. The reversing worm gear 82 is coaxially connected to the middle of the bidirectional screw 81. The reversing worm gear 82 and the reversing worm 83 mesh. The two ends of the bidirectional screw 81 are respectively threaded through and connected to one end of the split strip 511. The fourth driving member 831 drives the reversing worm gear 83 to rotate, which in turn drives the bidirectional screw 81 to rotate through the reversing worm wheel 82, causing the split strips 511 to move closer or further apart. Due to the restriction of the protrusion 611 and the limiting groove 512, the split strips 511 slide more stably.
