Description

Technical Field

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

[0002] In the crib manufacturing industry, the assembly line for folding cribs plays a vital role. The main task of this production line is to efficiently assemble the various components into a complete folding crib and ensure that its quality meets relevant standards.

[0003] Specifically, the assembly process of a folding crib usually includes the following key steps: First, the preliminary docking of the frame is carried out. During this process, the bed cover needs to be put into the appropriate position of the frame to ensure the appearance and comfort of the crib. Next, in order to enhance the stability of the structure, the joints of the frame need to be bolted and reinforced, which is an important part of ensuring the safety of the crib during use. Subsequently, anti-collision cloth strips are installed around the edge of the bed. This step is aimed at improving the safety and user experience of the crib. The anti-collision cloth strips can not only effectively prevent babies from colliding and getting injured while playing, but also add a sense 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 the various parts of the crib fit tightly to avoid looseness or damage during transportation and use. Finally, the crib is packed in a carton for final transportation and sale. Cartons not only provide additional protection, but also facilitate the printing of product information and barcodes and other labels for easy management and tracking.

[0029] The following is combined with Figure 1 To Attachment Figure 7 This application is described in further detail.

[0030] In order to increase the efficiency of crib assembly, the present application provides a crib assembly line, which includes a pre-installation station 11, a fixing station 12, an anti-collision cloth strip installation station 13, a folding station 14 and a packaging station 15. The stations are connected by a conveyor belt, so that the semi-finished products are conveyed in each station in turn. The pre-installation station 11 includes two workbenches, and the operator inspects and pre-joins the produced skeleton at one of the workbenches. On the other workbench, the operator unfolds the bed sheet and inspects the bed sheet. The bed sheet needs to be put on the skeleton, and some parts need to be disassembled and inserted into the bed sheet socket after the skeleton is disassembled. Apply force to the joints of several skeletons to tighten them. Then the semi-finished product is 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 uses an air-blowing screw feeder, which belongs to the prior art and will not be described here. An automatic screw locking machine is provided on the first robotic arm, and the automatic screw locking machine is combined with a screw feeder to form an automatic screw locking station to save manpower expenditure and speed up processing efficiency. According to the part of the crib that needs to be reinforced, the fixing station 12 can be divided into two stations, respectively locking the upper bolts and the lower bolts. Furthermore, a station for strapping and labeling can be set after the fixing station 12. The semi-finished product after reinforcement and labeling is sent to the anti-collision cloth strip installation station 13 to install anti-collision cloth strips around the edge of the bed. This step is intended to improve the safety and user experience of the crib. The anti-collision cloth strip can not only effectively prevent babies from colliding and getting injured while playing, but also add a sense of warmth and comfort to the crib. After completing the above steps, fold the finished crib for subsequent packaging. The folding process needs to ensure that the various components of the crib are tightly matched to avoid loosening or damage during transportation and use. A packing station 15 is set up at the back, including a station for rolling the folded baby crib and the matching bed board together, and putting the baby crib and bed board at the front station into a packing bag and zipping it up. This step is not only to protect the baby crib from damage from the external environment, but also to facilitate subsequent transportation and storage. Furthermore, in order to improve the moisture-proof and dust-proof effects, a layer of PE bag needs to be covered on the outer cover of the packing bag in the packing station 15. The sealing performance of the PE bag can effectively isolate air and moisture, thereby extending the service life of the baby crib. Finally, the PE bag containing the baby crib is packed into a carton for final transportation and sale. The carton not only provides additional protection, but also facilitates the printing of product information and barcodes and other labels, which is easy to manage and track. The packing station 15 includes a carton opener, a carton sealer, a stacker, etc., which belong to the prior art and will not be repeated here.

[0031] Furthermore, in order to make the installation efficiency of the cloth strips in the anti-collision cloth strip installation station 13 higher. This embodiment also provides an automated anti-collision cloth strip installation solution. It is worth noting that this embodiment is suitable for rectangular cribs, and the four edges of the space in the bed are provided with cloth openings for inserting cloth strips. The anti-collision cloth strips can be inserted into the bed sheet along their own length direction through the cloth openings to form surrounding barriers inside the crib. Specifically, the anti-collision cloth strip installation station 13 includes an installation table, a second mechanical arm 2, a base 315, a strip insertion assembly 3 and a bag opening assembly 5. The anti-collision cloth strip installation station 13 also includes a strip feeding assembly 7. The semi-finished product of the front station is delivered to the installation table by a conveyor belt. The anti-collision cloth strips are installed on the semi-finished product on the installation table. Among them, the strip feeding assembly 7 is arranged on one side of the installation table for conveying anti-collision cloth strips. The second mechanical arm 2 is arranged on one side of the installation table. The base 315 is connected to the working end of the second mechanical arm 2. The inserting strip assembly 3 is connected to the second mechanical arm 2 via the base 315. The inserting strip assembly 3 receives the anti-collision cloth strip and can deliver the anti-collision cloth strip into the crib after the movement of the second mechanical arm 2. The bag opening assembly 5 is arranged on the base 315, and is used to open the bag opening of the bed cover to expose the opening for inserting the anti-collision cloth strip.

[0032] Specifically, the state when the anti-collision cloth strip is placed in the bed cover is the vertical state of the anti-collision cloth strip. In the vertical state, the longest side of the anti-collision cloth strip is arranged horizontally, the short side is arranged along the gravity direction, and the thickness is in the same plane as the longest side. The strip feeding assembly 7 includes a strip feeding groove tube 71, a steering seat 72 and a plurality of conveying rollers 73. The strip feeding assembly 7 is arranged on the table body, and is used to place the strip feeding assembly 7 at a suitable height. The strip feeding groove tube 71 is connected to the steering seat 72. The strip feeding groove tube 71 is a U-shaped cross-sectional structure, and a plurality of anti-collision cloth strips can enter the strip feeding groove tube 71 along the long side direction and be in a vertical state. A plurality of conveying rollers 73 are connected to the bottom of the strip feeding groove tube 71 and rotated at a linear interval to convey the anti-collision cloth strip. The conveying rollers 73 are arranged horizontally, and the conveying rollers 73 are driven to rotate by a motor at the same time. Further, a quarter-circle arc-shaped steering groove 721 is provided in the steering seat 72. Both ends and the upper part of the steering groove 721 pass through the steering seat 72. One end of the steering groove 721 is connected to the end of the strip feeding groove tube 71. The other end of the steering groove 721 is connected to the outside and is parallel to the conveyor belt. The anti-collision cloth strip passes through the strip feeding groove tube 71 along the length direction and is sent into the steering groove 721 and is in a vertical state.

[0033] Furthermore, the strip feeding assembly 7 also includes a steering roller 74 and a stabilizing roller 75. The steering seat 72 is provided with a groove 722 along the radial direction of the steering groove 721. The steering roller 74 is rotatably connected in the groove 722. The steering roller 74 is vertically arranged in the groove 722, and a portion of the steering roller 74 penetrates into the steering groove 721 through the groove 722. When the anti-collision cloth strip is fed into the steering groove 721 through the strip feeding groove tube 71 and abuts against the steering roller 74, since the distance between the steering roller 74 and the inner wall of the steering groove 721 is set to be smaller than the thickness of the anti-collision cloth strip, the anti-collision cloth strip can be driven to slide under the friction force of the steering roller 74. The sliding seat is provided with a first driving member 741 for driving the steering roller 74 to rotate. The first driving member 741 is a motor. Two stabilizing rollers 75 are provided, and the two stabilizing rollers 75 are arranged at intervals at the exit of the turning groove 721, and are respectively located in the inner wall of the turning groove 721. The same stabilizing roller 75 partially intrudes into the turning groove 721, and the minimum interval between the two stabilizing rollers 75 is smaller than the width of the turning groove 721. Through the arrangement of the stabilizing rollers 75, when the anti-collision cloth strip moves out of the turning groove 721, the end of the anti-collision cloth strip can be stabilized to avoid deviation.

[0034] Furthermore, the strip inserting assembly 3 is connected to the second mechanical arm 2 through the base 315. The strip inserting assembly 3 can be driven by the second mechanical arm 2 to move to a position corresponding to the strip feeding assembly 7, so that the anti-collision cloth strip is sent to the strip inserting assembly 3 through the steering groove 721 to perform the anti-collision cloth strip operation. The strip inserting assembly 3 includes a reversing seat 31, and a power roller 32 and a plurality of strip feeding rollers 33 vertically arranged in the reversing seat 31. It is worth noting that the reversing seat 31 can rotate with the second mechanical arm 2. In this embodiment, the reversing seat 31 is in a horizontal state, that is, a state in which the anti-collision cloth strip in a vertical state can be received, as the initial state. The following are all descriptions in the initial state. The reversing seat 31 is provided with a docking groove 311, a reversing groove 312 and a strip feeding groove 313 which are connected in sequence. The base 315 is arranged at one end of the reversing seat 31 away from the outlet of the strip feeding groove 313.

The docking groove 311 is parallel to the feeding groove 313, and the length direction of the docking groove 311 corresponds to the exit direction of the steering groove 721. The reversing groove 312 is a half arc, and the two ends are connected to the docking groove 311 and one end of the feeding groove 313 respectively. The power roller 32 is vertically rotated and connected to the concentric part of the reversing groove 312, and part of the power roller 32 penetrates into the reversing groove 312, and 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 cloth strip, that is, the two are interference fit. The power roller 32 rotates to drive the anti-collision cloth strip to move by friction. A plurality of feeding rollers 33 are rotated and connected to the reversing seat 31 along a straight line at intervals. The feeding roller 33 partially penetrates into the feeding groove 313. The distance between the outer wall of the feeding roller 33 and the inner wall of the feeding groove 313 is slightly less than the thickness of the anti-collision cloth strip. A docking notch 34 is provided on the outer side of the reversing seat 31. The docking notch 34 is connected to the docking groove 311. The reversing seat 31 can move to connect the docking groove 311 with the steering groove 721. The shape of the docking notch 34 corresponds to the shape of the steering seat 72.

[0037] Specifically, the bag opening assembly 5 includes a support sheet 51 and a first control assembly 6. One end of the support sheet 51 is connected to the reversing seat 31 through the first control assembly 6, and the support sheet 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 sheet 51 extends in the direction away from the reversing seat 31. One end of the support sheet 51 intrudes into the length extension range of the feeding groove 313 and then tilts to extend along the length direction of the feeding groove 313. The inner wall of the feeding groove 313 on the side away from the docking groove 311 is the top, and the inner wall of the feeding groove 313 on the side close to the docking groove 311 is the bottom. Initially, the support sheet 51 passes from the top of the feeding groove 313 over the length range of the feeding groove 313 to the bottom of the feeding groove 313. At this time, the end of the support sheet 51 can penetrate into the pocket of the bed cover. The first control assembly 6 can control the support sheet 51 to move horizontally and leave the length extension range of the feeding groove 313. When the support sheet 51 is inserted into the pocket, the first control assembly 6 controls the support sheet 51 to translate, thereby driving the bed sheet to deform and forming an opening for the anti-collision cloth strip to be inserted. The end of the support sheet 51 is arc-shaped to prevent the bed sheet from being damaged when inserted into the pocket.
