[0034] The present invention provides a distribution line device 10 .

[0035] See also Figure 1 and Figure 3 In one embodiment of the present invention, the distribution line device 10 is applied to a production line body having a machine to transfer workpieces between the production line body and the machine. The distribution line device 10 includes a frame 100, a distribution component 300 and at least one line body component 200. The line body component 200 is arranged on the frame 100, and the line body component 200 is used for inputting or outputting the workpiece into or out of the distribution line device 10; the distribution component 300 includes a rotating component 320 arranged on the frame 100, and a transfer component 310 arranged on the rotating component 320. The rotating component 320 can drive the transfer component 310 to rotate relative to the frame 100, so that the transfer component 310 can dock with the line body component 200, or dock with the machine, so as to input or output the workpiece into or out of the machine.

[0036] Specifically, the frame 100 is the main supporting structure of the distribution line device 10, which is used to fix and support the distribution component 300 and the line body component 200, ensuring the stability of the installation of each component. A hood can also be provided on the frame 100, and the hood can detachably cover the distribution component 300 and the line body component 200. The hood can prevent the operator from accidentally contacting high-speed running components, such as the transmission chain, the rotating component 320, etc., thereby significantly reducing the incidence of work-related accidents. In addition, the hood can also prevent dust, debris or other foreign objects from entering the interior of the machine, protecting the equipment from damage and extending its service life. The frame 100 can also be equipped with an electrical box to supply power to the distribution component 300 and the line body component 200, providing power for the movement of the distribution component 300 and the line body component 200.

[0037] The distribution line device 10 can be provided with a line body component 200, which serves as a feed line body component 200a and is additionally equipped with a docking platform line body as a discharge line body; the line body component 200 can also serve as a discharge line body component 200b and is additionally equipped with a docking platform line body as a feed line body. The distribution line device 10 can be provided with multiple line body components 200, and the multiple line body components 200 are distributed in the circumferential direction of the rotation of the transfer component 310. The multiple line body components 200 can all serve as feed line body components 200a, or all serve as discharge line body components 200b, or at least one serves as a feed line body component 200a, and the rest serve as discharge line body components 200b.

[0038] When two line assemblies 200 are provided, the two line assemblies 200 can be spaced apart along the X-axis direction for input and output of workpieces, and the line assemblies 200 extend along the X-axis direction so that the workpieces can move along the X-axis direction on the line assemblies 200. The upstream one of the two line assemblies 200 is the feed line assembly 200a. The feed line assembly 200a can be used to receive workpieces from the preceding station of the production line, or it can be equipped with a material box, in which multiple workpieces are stacked and can fall on the feed line assembly 200a in sequence. The downstream one of the two line assemblies 200 is the discharge line assembly 200b. The discharge line assembly 200b can be used to transfer the processed workpieces on the machine to the subsequent station of the production line, or it can be equipped with a material box, in which the processed workpieces are stored. The two line assemblies 200 can be conveyor belts, rollers or other forms of transmission components.

[0039] The distribution assembly 300 includes a rotating assembly 320 and a transfer assembly 310. The rotating assembly 320 is mounted on the frame 100, and the transfer assembly 310 is mounted on the rotating assembly 320. The rotating assembly 320 is responsible for driving the rotational movement of the transfer assembly 310. The transfer assembly 310 is in direct contact with the workpiece and is responsible for the actual handling of the workpiece. Driven by the rotating assembly 320, the transfer assembly 310 can rotate relative to the frame 100, thereby achieving docking with the line assembly 200 or the machine. It can be understood that when the transfer assembly 310 is docked with the line assembly 20, the workpiece can be input from the preceding station of the production line to the transfer assembly 310 through the feeding line assembly 200a, or output from the transfer assembly 310 to the subsequent station of the production line through the discharging line assembly 200b. When the transfer assembly 310 is docked with the machine, the workpiece can be input from the transfer assembly 310 to the machine, or output from the machine to the transfer assembly 310.

[0040] Therefore, the technical solution of the present invention can realize the transfer of workpieces between the production line and the machine by rotatably docking the transfer component 310 with the line component 200 or the machine. There is no need to set up a multi-axis module and a manipulator to realize the transfer of the workpiece, and the distribution line device 10 does not need to adopt a high-precision servo motor and a complex motion control system. Therefore, while realizing the transfer of workpieces between the production line and the machine, the production cost of the distribution line device 10 is reduced.

[0041] In one embodiment, see Figure 1 and Figure 4 The distribution line device 10 also includes a cache component 400, which is arranged above the line body component 200; the distribution component 300 also includes a lifting component 330 arranged on the frame 100, and the rotating component 320 is driven and connected to the lifting component 330 and can move along the Z-axis direction to enable the transfer component 310 to dock with the cache component 400.

[0042] The cache component 400 is arranged above the line body component 200, and can be arranged above the feed line body component 200a, or can be arranged above the discharge line body component 200b, or can be arranged above multiple line body components 200 with a cache component 400. The main function of the cache component 400 is to serve as a temporary storage area for temporarily storing workpieces waiting to be processed or waiting for the next operation, thereby avoiding congestion of workpieces on the production line, especially when the upstream production speed does not match the downstream processing capacity, the cache component 400 can play a buffering role, avoiding the production line from pausing due to waiting for processing, thereby improving overall production efficiency. The lifting component 330 is installed on the frame 100 and is driven by the rotating component 320, and can drive the rotating component 320 and the transfer component 310 to move along the Z-axis direction. Through the control of the lifting component 330, the transfer component 310 can not only realize rotation in the XY plane, but also realize lifting and lowering in the Z-axis direction, so that the transfer component 310 can be accurately docked with the line body component 200 or the cache component 400 at different heights. By combining rotation and lifting movements, the transfer component 310 can selectively dock with the line component 200, the machine and the cache component 400, thereby realizing flexible transfer of workpieces between the line component 200, the machine and the cache component 400, which not only improves the automation level of the production line, but also avoids congestion of workpieces on the production line, thereby improving overall production efficiency.

[0043] Furthermore, in conventional production lines, the buffering station is typically located outside the production line, resulting in a large footprint for the overall production equipment. Furthermore, the larger the buffering space of the buffering station, the larger the footprint of the production equipment. However, the buffer assembly 400 of the distribution line device 10 of the present invention is located above the line assembly 200, fully utilizing the space above the line assembly 200 without occupying the space outside the line assembly 200, thereby reducing the footprint of the distribution line device 10. Furthermore, the buffer assembly 400 can be expanded based on the length of the line assembly 200, significantly improving the buffering capacity of the buffer assembly 400.

[0044] In one embodiment, see Figure 4 The cache component 400 includes two cache side plates 410 extending along the X-axis direction and a plurality of first conveying components 420. The two cache side plates 410 are arranged above the line component 200 at intervals along the Y-axis direction, and the plurality of first conveying components 420 are arranged on the cache side plates 410 at intervals along the Z-axis direction. The first conveying components 420 are used to store workpieces.

[0045] Two cache side plates 410 are arranged above the linear assembly 200 at intervals along the Y-axis direction, forming the basic frame of the cache assembly 400. The cache side plates 410 not only provide a supporting structure, but also limit the boundaries of the storage area of ​​the workpiece, ensuring that the workpiece will not shift or fall during the caching process. Each first conveying assembly 420 can independently store one or more workpieces. Multiple first conveying assemblies 420 are arranged at intervals along the Z-axis direction, so that the cache assembly 400 forms a multi-layer buffer space in the Z-axis direction, so that the cache assembly 400 can accommodate different numbers and types of workpieces at the same time, increasing the cache capacity and flexibility. The first conveying assembly 420 can take a variety of forms, such as rollers, belts or chains. The first conveying assembly 420 can not only store workpieces, but also convey workpieces to change the position of the workpieces on the first conveying assembly 420, so that the first conveying assembly 420 can accommodate more workpieces and can output workpieces at different positions to the transfer assembly 310.

[0046] Workpieces can be temporarily placed within the buffer assembly 400 via the first conveyor assembly 420. This allows the production line to maintain continuous operation even when processing speeds fluctuate or when upstream and downstream processes are unbalanced, avoiding production halts caused by waiting and thereby improving the flexibility and responsiveness of the production line. Furthermore, the multi-layered buffer space increases the buffering capacity of the buffer assembly 400, improving overall production efficiency.

[0047] In one embodiment, see Figure 3The transfer assembly 310 includes a first support frame and two second conveying assemblies 313. The first support frame includes a supporting base plate 311 and two supporting side plates 312. The supporting base plate 311 is arranged on the rotating assembly 320. The two supporting side plates 312 are connected to the opposite sides of the supporting base plate 311; the two second conveying assemblies 313 are installed on the two supporting side plates 312 one by one.

[0048] The first support frame serves as the main structure of the transfer assembly 310 and is composed of a support base plate 311 and two support side plates 312. The support base plate 311 is directly mounted on the rotating assembly 320 and serves as the bottom platform of the entire transfer assembly 310. The two support side plates 312 are connected on opposite sides of the support base plate 311 to form a stable frame, which increases the rigidity and strength of the overall structure. The second conveying assembly 313 is the part that directly contacts and transports the workpiece and is respectively mounted on the two support side plates 312. The two second conveying assemblies 313 are arranged relative to each other to form a smooth conveying track for facilitating the conveyance of the workpiece. The second conveying assembly 313 can take a variety of forms, such as rollers, belts or chains. When the rotating assembly 320 drives the first support frame to rotate, the two second conveying assemblies 313 also move accordingly, thereby achieving precise docking with the line assembly 200, the machine or the cache assembly 400.

[0049] In one embodiment, see Figure 3 The rotating assembly 320 includes a mounting seat 321, a synchronous wheel 322, a first driving member 323 and a rotating bearing 324. The mounting seat 321 is driven and connected to the lifting assembly 330. The first driving member 323 is installed on the mounting seat 321 and is driven and connected to the synchronous wheel 322. The supporting base plate 311 is arranged above the synchronous wheel 322 and is connected to the synchronous wheel 322. The synchronous wheel 322 is mounted on the mounting seat 321 through the rotating bearing 324.

[0050] The mounting seat 321 serves as the base of the rotating assembly 320 and is connected to and driven by the lifting assembly 330. It can move along the Z-axis direction under the drive of the lifting assembly 330. The mounting seat 321 not only provides support, but also serves as the installation base for other components of the rotating assembly 320, ensuring the stability of the entire assembly. The synchronous wheel 322 is the basis for realizing the rotation of the transfer assembly 310. The supporting base 311 is directly arranged above the synchronous wheel 322 and is connected to it. The rotating bearing 324 is a key component in the rotating assembly 320 to ensure the smoothness of rotation. It is located between the synchronous wheel 322 and the mounting seat 321. By reducing friction, it allows the synchronous wheel 322 to rotate easily under drive. The first driving member 323 (such as an electric motor or a hydraulic motor) is mounted on the mounting seat 321, and the synchronous wheel 322 is mounted on the mounting seat 321 through the rotating bearing 324 and can rotate under the drive of the first driving member 323. The design of the synchronous wheel 322 ensures the smoothness and consistency of the rotation action, and can maintain good dynamic balance even at high-speed rotation.

[0051] The first drive member 323 drives the synchronous wheel 322 to rotate, thereby driving the support base 311 and the transfer assembly 310 thereon to rotate together, achieving precise transfer of the workpiece in different directions. This not only ensures the efficiency and precision of the rotation movement, but also, through combined use with the lifting assembly 330, the transfer assembly 310 and the workpiece thereon can not only rotate in the XY plane, but also be lifted and lowered in the Z-axis direction, allowing the transfer assembly 310 to dock with the machine and to selectively dock with the line assembly 200 or the buffer assembly 400 at different heights. Moreover, the rotating assembly 320 has a simple structure, and the synchronous wheel 322 and the rotating bearing 324 are low-cost to manufacture, eliminating the need for a high-precision servo motor and a complex motion control system, thereby reducing the production cost of the distribution line device 10.

[0052] In one embodiment, see Figure 3 and Figure 7 The transfer assembly 310 further includes a plurality of pressing assemblies 314 , which are disposed at both ends of the two supporting side plates 312 in the length direction. The pressing assemblies 314 are used to elastically abut against the upper surface of the workpiece.

[0053] The transfer assembly 310 is equipped with multiple press assemblies 314, evenly distributed along the length of the two support side plates 312. This ensures balanced force on the workpiece during transfer, preventing it from shifting, tilting, or falling due to a shift in its center of gravity, and ensuring its stability and safety. The press assemblies 314 are designed with an elastic abutment feature that automatically adjusts pressure based on the shape and size of the workpiece, ensuring sufficient contact force to abut the workpiece while preventing excessive pressure that could hinder movement or cause deformation or damage.

[0054] Specifically, the pressing assembly 314 includes an adjustment plate 3141, a pressing roller body 3144, a pressing roller shaft 3143, and a pressing roller spring 3142. The adjustment plate 3141 is mounted on the supporting side plate 312. One end of the pressing roller spring 3142 is connected to the adjustment plate 3141, and the other end is connected to the pressing roller body 3144 via the pressing roller shaft 3143. The pressing roller body 3144 can rotate around the pressing roller shaft 3143. In its natural state, the pressing roller body 3144 abuts the upper surface of the second conveying assembly 313. When the workpiece enters the load-bearing area of ​​the transfer assembly 310, the pressing roller body 3144 rolls in contact with the workpiece. Under the action of the pressing roller spring 3142, the pressing roller body 3144 is lifted, causing the pressure body to elastically abut against the upper surface of the workpiece, effectively preventing the workpiece from slipping or falling, thereby ensuring smooth movement of the workpiece. In other embodiments, the pressing roller can be replaced with a ball bearing, using a combination of a ball bearing and a spring.

[0055] In one embodiment, see Figure 4 and Figure 5 The line assembly 200 includes two second support frames 210 and two third transmission assemblies 220. The two second support frames 210 are arranged on the frame 100 at intervals along the Y-axis direction and extend along the X-axis direction. The two third transmission assemblies 220 are installed on the two second support frames 210 in a one-to-one correspondence, so that the workpiece can move along the X-axis direction.

[0056] The second support frames 210 are the basic structure of the line assembly 200. They are arranged on the frame 100 at intervals along the Y-axis direction and extend along the X-axis direction, providing stable support and guidance for the third conveying assembly 220. The third conveying assembly 220 is a component directly involved in the transmission of the workpiece. They are installed on the two second support frames 210 in a one-to-one correspondence, forming a track for the workpiece to move along the X-axis direction. The third conveying assembly 220 can be a transmission mechanism such as a roller, a chain, or a belt. Under the action of the third conveying assembly 220, the workpiece can move smoothly along the X-axis direction. When the transfer assembly 310 is docked with the two line assemblies 200, the workpiece can be smoothly transferred from the third conveying assembly 220 of the feed line assembly 200a to the transfer assembly 310, or from the transfer assembly 310 to the third conveying assembly 220 of the discharge line assembly 200b, thereby realizing efficient transfer of the workpiece between the production line and the machine and cache assembly 400.

[0057] In one embodiment, the distribution line device 10 also includes a stop assembly 500, which includes a mounting frame 510, a second driving member 520 and a stop block 530. The mounting frame 510 is arranged at one end of the transfer assembly 310 and / or the line body assembly 200 located downstream of itself. The second driving member 520 is installed on the mounting frame 510 and drives the connected stop block 530 so that the stop block 530 can move along the Z-axis direction to stop the workpiece.

[0058] See also Figure 6 The mounting frame 510 provides an installation base for the second driving member 520 and the stop block 530, ensuring the stability of the installation of the stop assembly 500. The second driving member 520 is mounted on the mounting frame 510, and stops or releases the workpiece by driving the stop block 530 to move along the Z-axis direction. The stop block 530 is the part that directly contacts the workpiece, and is used to prevent the workpiece from moving forward or guide the workpiece to stop at a predetermined position. The second driving member 520 can be configured as an electromagnet, and the stop block 530 can be configured as a magnetic member. The electromagnet and the magnetic member can also be connected by an elastic member. In the natural state, the electromagnet is in the power-off state, the magnetic member is away from the electromagnet, and is in a position to block the workpiece. When the workpiece needs to be released, the electromagnet is in the power-on state, and the magnetic member is close to the electromagnet, so that the position of the magnetic member is lowered to facilitate the workpiece to leave. The elastic member acts as a reset member, which can reset the magnetic member to the stop state after the electromagnet is powered off again.

[0059] In one embodiment, the distribution line device 10 further includes a plurality of in-position sensing components 600, which are disposed at both ends of the transfer component 310 in the length direction, wherein at least one in-position sensing component 600 is installed on the stop component 500 and is located on a side upstream of the stop component 500.

[0060] A plurality of in-place sensing components 600 are provided at both ends of the transfer component 310 in the length direction, that is, both the upstream end and the downstream end of the transfer component 310 are provided with an in-place sensing component 600. The in-place sensing component 600 located at the upstream end is used to sense whether the workpiece has entered the transfer component 310, and two in-place sensing components 600 are provided at the downstream end. The two in-place sensing components 600 are provided on both sides of the transfer component 310 in the Y-axis direction, one of which is installed on a side of the stop component 500 close to the upstream end, and the other is closer to the downstream end, so that the two in-place sensing components 600 are staggered. The in-place sensing component 600 installed on the stop component 500 is used to detect whether the workpiece has correctly reached the stop position, and the other in-place sensing component 600 is used to sense whether the workpiece has left the transfer component 310, so that information on whether the workpiece is stuck can be obtained in a timely manner.

[0061] In one embodiment, multiple in-position sensing components 600 are disposed at both ends of the length of the line assembly 200, i.e., a in-position sensing component 600 is disposed at both the upstream and downstream ends of the line assembly 200. The distribution of the in-position sensing components 600 on the line assembly 200 is substantially similar to the distribution of the in-position sensing components 600 on the transfer assembly 310 and will not be further described here.

[0062] The in-position sensing assembly 600 can be mounted on the mounting frame 510, the second driving member 520, or the frame 100, the first support frame, or the second support frame 210 near the stop assembly 500. The in-position sensing assembly 600 can be a photoelectric sensor, a proximity switch, or a magnetic sensor. The in-position sensing assembly 600 can provide real-time feedback of workpiece status information to the control system, ensuring accurate and reliable workpiece processing.

[0063] In one embodiment, see Figure 3 The mounting frame 510 is fixed at the downstream end of the transfer component 310 , that is, the downstream end of the transfer component 310 is installed with the stop component 500 and the in-position sensing component 600 .

[0064] In another embodiment, see Figure 4 The mounting frame 510 is fixed at the downstream end of the line assembly 200 , that is, the downstream end of the line assembly 200 is installed with the stop assembly 500 and the position sensing assembly 600 .

[0065] In another embodiment, a stopper assembly 500 and an in-position sensing assembly 600 are installed at the downstream end of the transfer assembly 310 and the downstream end of the line assembly 200 .

[0066] In addition, a stopper assembly 500 and an in-position sensing assembly 600 may also be provided at one end of the cache assembly 400 away from the distribution assembly 300 .

[0067] Through the collaborative work of the stopper assembly 500 and the in-position sensing assembly 600, the dispensing line device 10 achieves precise control and positioning of the workpiece, ensuring stability and safety during the workpiece transfer process. When the workpiece reaches the designated position, the stopper 530 engages, preventing further movement. Simultaneously, the in-position sensing assembly 600 detects the workpiece in-position signal, notifying the control system that the workpiece is ready for further processing. Once the workpiece is processed or needs to be transferred further, the stopper 530 descends to release the workpiece.

[0068] In other embodiments, the second driving member 520 may be configured as a motor or a cylinder to directly drive the stop block 530 to move along the Z axis, or to drive the stop block 530 to move along the Z axis via a screw rod or the like.

[0069] In one embodiment, see Figure 3 The distribution line device 10 further includes an identification component 700 , which is disposed on the rack 100 or the transfer component 310 , and is used to identify information of the workpiece.

[0070] The identification component 700 can be installed at an appropriate position on the frame 100 or the line component 200 to ensure that the required information can be accurately captured when the workpiece passes by. In one embodiment, the identification component 700 includes a barcode scanner, which is installed at the downstream end of the transfer component 310 and is installed in the middle of the edge of the support base plate 311. In another embodiment, the identification component 700 includes a crossbeam and a barcode scanner. The crossbeam is mounted on the top of the two supporting side panels 312, and the barcode scanner is installed in the middle of the crossbeam. The barcode scanner has a better scanning viewing angle. Or the identification component 700 includes two columns, a crossbeam and a barcode scanner. The two columns are respectively arranged on the outside of the two supporting side panels 312 and are installed on the frame 100. The crossbeam is located above the column and connects the two columns. The barcode scanner is installed in the middle of the crossbeam. In other embodiments, the barcode scanner can also be installed on one of the supporting side panels 312.

[0071] The primary function of the identification component 700 is to read identification information on workpieces, such as barcodes, QR codes, RFID tags, or visual features. Using this information, the control system can identify key data such as the workpiece type, batch, and processing status, thereby determining the workpiece's subsequent processing path and operating instructions. Based on the information provided by the identification component 700, the control system can make intelligent decisions, such as selecting the correct processing program, determining the workpiece's storage location, or adjusting the production line speed. The identification component 700 can also be used for quality control and product traceability, recording the processing history and current status of each workpiece.

[0072] In one embodiment, the machine includes a first platform and a second platform disposed on opposite sides of the production line body, and each of the first platform and the second platform is provided with at least one transfer component 310 that can selectively dock with the first platform and the second platform.

[0073] The machine includes a first body and a second body located on opposite sides of the production line body, so that the first body and the second body can operate simultaneously or alternately without interfering with the normal operation of the production line body, which not only improves space utilization, but also allows the production line body to flexibly switch between different machines to adapt to changing production needs. Whether it is the first body or the second body, each side is provided with at least one machine, and the transfer component 310 can be docked with any one of the first body and the second body. The transfer component 310 can select the most suitable machine for workpiece processing as needed, so that each side of the production line body can independently process multiple workpieces or execute different processing procedures, increasing the versatility and productivity of the production line. Of course, the first body and the second body can also process the same workpiece at the same time, improving the processing efficiency of the production line. In addition, in the event of maintenance or failure of certain machines, the production line can also continue to operate by switching to other available machines, reducing downtime and production losses.

[0074] In one embodiment, the distribution line device 10 also includes a rotating assembly 800, which includes a limiting slider 820, a fixed seat 810 connected to the frame 100, and a limiting shaft 840 and a rotating shaft 830 connected to the line body assembly 200. The rotating shaft 830 is passed through the end of the fixed seat 810 away from the frame 100 and can rotate relative to the fixed seat 810. The limiting slider 820 is provided on the upper surface of the fixed seat 810 and can slide relative to the fixed seat 810 along the X-axis direction to limit the limiting shaft 840 to the end of the fixed seat 810 close to the frame 100, so that the line body assembly 200 has an expanded state extending along the X-axis direction, or the limiting shaft 840 is exposed to the outside, and the limiting shaft 840 can be detached from the fixed seat 810, so that the line body assembly 200 has a stored state extending along the Z-axis direction.

[0075] The limiting shaft 840 and the rotating shaft 830 are both connected to the line assembly 200. The end of the rotating shaft 830 away from the line assembly 200 is provided on the fixed seat 810 and can rotate relative to the fixed seat 810, so that the line assembly 200 can rotate with the axis of the rotating shaft 830 as the rotation center. The end of the limiting shaft 840 away from the line assembly 200 can be limited to the fixed seat 810 under the action of the limiting slider 820, and the limiting shaft 840 and the rotating shaft 830 are spaced apart along the X-axis direction on the fixed seat 810, so that the line assembly 200 is in an expanded state extending along the X-axis direction. In addition, since the limiting shaft 840 is limited to the fixed seat 810 by the limiting slider 820, the line assembly 200 will not rotate at this time and can always maintain the expanded state, thereby improving the stability of the line assembly 200 during operation. When the limit slider 820 slides and exposes the limit shaft 840, the limit shaft 840 can be separated from the fixed seat 810 without the limiting action of the limit slider 820, and rotate around the rotating shaft 830 with the axis of the rotating shaft 830 as the rotation center, so as to be spaced apart from the rotating shaft 830 along the Z-axis direction, so that the line body assembly 200 is in a stored state extending along the Z-axis direction.

[0076] It is understood that in the unfolded state, the line assembly 200 extends along the X-axis, allowing workpieces to be smoothly transported along the production line. In the retracted state, the line assembly 200 folds along the Z-axis, reducing the footprint and facilitating transportation of the distribution line device 10 or saving space when not in use.

[0077] In one embodiment, the upper surface of the fixing base 810 is formed with two first receiving grooves 811 and a second receiving groove 812 distributed along the X-axis. The first receiving groove 811 is formed at the end of the fixing base 810 away from the frame 100. One end of the rotating shaft 830 is disposed within the first receiving groove 811 and is capable of rotating about its axis within the first receiving groove 811. The limiting slider 820 can slide to a notch that blocks the second receiving groove 812 to retain the limiting shaft 840 within the second receiving groove 812, or slide and open the notch of the second receiving groove 812 to expose the limiting shaft 840, allowing the limiting shaft 840 to be disengaged from the second receiving groove 812.

[0078] In one embodiment, the rotation assembly 800 further includes a fastener 850. The limit slider 820 is provided with a clearance hole 821 for the fastener 850 to pass through. The clearance hole 821 extends along the X-axis. The fastener 850 passes through the clearance hole 821. When the limit slider 820 slides, the fastener 850 and the clearance hole 821 move relative to each other in the X-axis direction. The fastener 850 is inserted into the fixed seat 810 and threadedly connected thereto. The outer wall of the fastener 850 is provided with a pressing piece 860. By rotating the fastener 850 forward, the pressing piece 860 abuts against the upper surface of the limit slider 820 and presses the limit slider 820, thereby securing the limit slider 820 relative to the fixed seat 810. The limit slider 820 can thereby retain the rotating shaft 830 and the limiting shaft 840 within the first receiving groove 811 and the second receiving groove 812, respectively. By rotating the fastener 850 in the opposite direction, a gap is created between the pressing piece 860 and the upper surface of the limiting slider 820, thereby releasing the fixed connection between the limiting slider 820 and the fixing seat 810, allowing the limiting slider 820 to slide along the X-axis direction, thereby allowing the limiting shaft 840 to disengage from the second receiving groove 812. To improve the convenience of rotating the fastener 850, a wrench can also be provided on the outer periphery of the fastener 850.

[0079] In other embodiments, the limiting slider 820 may be displaced along the Z axis by providing an elastic member or a driving device, so that the limiting slider 820 can press the fixing seat 810 or have a gap with the fixing seat 810 .

[0080] The workflow of the distribution line device 10 is as follows:

[0081] After the workpiece enters the feed line assembly 200a along the positive direction of the X-axis (the direction of movement of the workpiece from upstream to downstream of the production line is the positive direction of the X-axis, and vice versa), the in-position sensing assembly 600 on the feed line assembly 200a is triggered. The third conveying assembly 220 continues to convey along the positive direction of the X-axis. The workpiece triggers the in-position sensing assembly 600 on the feed line assembly. Then the feed stop assembly 500 blocks the workpiece. At this time, the third conveying assembly 220 stops conveying, and the transfer assembly 310 rotates back to zero and extends along the X-axis to dock with the feed line assembly 200a. The second conveying assembly 313 begins to convey along the positive direction of the X-axis. The workpiece flows into the transfer assembly 310. The workpiece triggers the in-position sensing assembly 600 on the transfer assembly 310. The stop assembly 500 on the transfer assembly 310 blocks the workpiece. The identification assembly 700 scans the code to identify the workpiece information.

[0082] If the workpiece is not from this workstation, the stop assembly 500 on the transfer assembly 310 will allow the workpiece to flow out, and the workpiece will flow into the discharge line assembly 200b until it flows into the next production line.

[0083] If the workpiece belongs to this workstation, the second conveying assembly 313 stops conveying. If the first platform is working and the workpiece happens to be on the first platform, the lifting assembly 330 drives the rotating assembly 320 and the transfer assembly 310 to rise, and the transfer assembly 310 rises to be flush with the upper surface of one group of the first conveying assemblies 420 of the cache assembly 400. The first conveying assembly 420 and the second conveying assembly 313 convey in opposite directions along the X-axis, and the workpiece is sent into the cache track of one group of the first conveying assemblies 420 through the pressing assembly 314 until the workpiece triggers the cache in place sensing assembly 600 and hits the limit. At this time, the first conveying assembly 420 and the second conveying assembly 313 stop running, and the lifting assembly 330 drives the rotating assembly 320 and the transfer assembly 310 to descend, and the rotating assembly 320 and the transfer assembly 310 return to their initial positions.

[0084] If the second stage is working and the workpiece is exactly on the second stage, the workpiece is placed in the buffer track of another set of first conveying components 420. The process is roughly the same as the above process and will not be repeated here.

[0085] When the first platform needs to output the workpiece, in order to prevent the plate from falling, the feed stop assembly 500 will not release the next workpiece. The transfer assembly 310 has a transfer inlet docking with the feed line assembly 200a, and a transfer outlet docking with the discharge line assembly 200b. At this time, the transfer assembly 310 rotates to the transfer outlet and docks with the first platform, and the second conveying assembly 313 starts to convey. The workpiece flows out of the first platform and enters the transfer assembly 310. The workpiece triggers the in-position sensing assembly 600 on the transfer assembly 310. The stop assembly 500 on the transfer assembly 310 blocks the workpiece. The identification assembly 700 scans the code again and the transfer assembly 310 rotates back to the initial position. The stop assembly 500 on the transfer assembly 310 releases the outflow, and the workpiece will flow into the discharge line assembly 200b until it flows into the next line. At this time, the stop assembly 500 on the transfer assembly 310 returns to the origin (that is, the stop assembly 500 is in a stop state).

[0086] The lifting assembly 330 drives the rotating assembly 320 and the transfer assembly 310 to rise, and the transfer assembly 310 rises to be flush with the upper surface of a group of first conveying assemblies 420 corresponding to the first platform. At this time, the first conveying assembly 420 and the second conveying assembly 313 are conveyed in the positive direction along the X-axis, and the workpiece (unprocessed) flows from the cache track of the first conveying assembly 420 into the transfer assembly 310. The workpiece triggers the in-position sensing assembly 600 on the transfer assembly 310, and the stop assembly 500 on the transfer assembly 310 blocks the workpiece. After the lifting assembly 330 drives the rotating assembly 320 and the transfer assembly 310 to descend, the transfer assembly 310 rotates again to the transfer exit to dock with the first platform, and sends the workpiece (unprocessed) to the first platform. After that, the second conveying assembly 313 stops running, and the transfer assembly 310 rotates back to its initial position.

[0087] When the second stage needs to output a workpiece, the process is roughly the same as that of the first stage, and will not be repeated here.

[0088] The distribution line device 10 proposed in the present invention can freely rotate through the transfer component 310 to dock with the machines on opposite sides of the production line body, so as to realize multi-directional conveying of workpieces, avoid the dependence on multi-axis modules and robots when transferring workpieces in traditional production line equipment, reduce the production cost of the distribution line device 10, and thus reduce the overall cost of the production line equipment. By arranging the cache component 400 above the line body component 200, not only the problem of congestion caused by workpieces waiting for processing is avoided, but also the problem of large floor space occupied by traditional cache tables is solved. By arranging the identification component 700, the distribution line device 10 can be connected to the MES (Manufacturing Execution System), and combined with the cache component 400, the scheduling function is realized to improve production efficiency and flexibility. By arranging the rotating component 800, the two line body components 200 can be folded for easy storage, thereby facilitating transportation.
