[0059] Embodiment 1:

[0060] This embodiment provides a PLC module assembly and packaging system for assembling panels of several types of PLC components 16 and packaging them into boxes.

[0061] It should be noted that the PLC component 16 in this embodiment is a semi-finished product, but only some external panels need to be installed to form the final product package, and all the previous test items have been completed.

[0062] Reference Figure 1 The figure shows the overall layout of an assembly and packaging system, which specifically includes a feeding area 1, an assembly area 2, a small box packaging area 3 and a large box packaging area 4.

[0063] Among them, the feeding area 1 is used to connect with the front-end workbench or conveying equipment, which itself has one or more track structures. Since the lower part of the PLC component 16 has a standard groove structure for installation and fixation, the sliding guide and limiting effect is achieved by snapping with the track. And because it is a standard groove structure, PLC components 16 of various specifications can share one track for transmission.

[0064] The assembly area 2 has an assembly table 9 for transmitting the PLC components 16 entering from the feed area 1, and a number of assembly panel stations are provided on both sides of the transmission line. The panels to be installed include top plates, fin plates and side plates in sequence. Each type of panel is surrounded by the assembly table 9. By setting up appropriate material conveying equipment, the panel materials can be transferred out of the feed container and installed at the corresponding stations.

[0065] The PLC component 16 after the assembly of the board is the finished PLC module, which needs to be placed separately in the small packaging box 27. At the same time, a disc and an instruction manual for tutorial instructions are also placed in the small packaging box 27. The small packaging box 27 has a variety of specifications, which are suitable for packaging the corresponding PLC components 16. When the PLC component 16 is placed in the small packaging box 27, the automatic packaging equipment in the system will package the small packaging box 27 and transport it to the large box packaging area 4.

[0066] In the large box packaging area 4, large packaging boxes 28 of uniform specifications are used, and according to the sizes of small packaging boxes 27, they are arranged in different quantities and arrangements in the large packaging boxes 28 in the large box packaging area 4, and finally the whole process is completed after packaging.

[0067] Reference Figure 1 Among the four areas, the three areas except the feeding area 1 are connected end to end and are arranged in the same site in a U-shaped or concave-shaped top-view layout. Auxiliary mechanisms are respectively provided on the inner and outer sides thereof, so as to rotate a production line and improve the utilization rate of the site.

[0068] Further, refer to Figure 2-Figure 17 In this embodiment, structural optimization and limitation are performed on the above-mentioned assembly and packaging system.

[0069] Various transmission mechanisms are used in different areas of the whole system for transmission. After the materials enter from the feeding area 1, they are transported in the form of PLC components 16, small packaging boxes 27 and large packaging boxes 28. The PLC components 16 are assembled in the assembly area 2, moved to the small box packaging area 3 to form a small packaging box 27, and moved to the large box packaging area 4 to form a large packaging box 28 of several small packaging boxes 27. Figure 2-Figure 5The figure shows the layout of the entire assembly and packaging system from different angles. From the feeding area 1 to the assembly area 2, from the assembly area 2 to the small box packaging area 3, and from the small box packaging area 3 to the large box packaging area 4, there is a freely movable robotic arm to realize the transfer of materials and the packaging of some parts.

[0070] The robot arm in this embodiment adopts a six-axis robot arm structure, which can move objects within a cylindrical area formed by a circular range with the circular range as the base. Different grippers are set at the end of each robot arm for different materials. In this embodiment, the grippers are used to generally refer to all mechanisms for grasping / releasing objects.

[0071] Reference Figure 6 , the assembly and packaging system in this embodiment is specifically described.

[0072] Reference Figure 7 The figure shows the terminal structural features of the feeding area 1 in this embodiment. The feeding area 1 has two parallel feeding tracks 8, and two PLC components 16 are placed at the ends of the feeding tracks 8. Figure 7 As can be seen in the figure, each feed track 8 adopts an inverted T-shaped cross-section structure, which can be locked and limited with the bottom groove structure of the PLC component 16. The PLC component 16 at the end of the feed track 8 is transferred to the assembly area 2 by the first robot 5 arranged between the feed area 1 and the assembly area 2 in the figure.

[0073] The assembly area 2 is an integral assembly table 9 structure, and a PLC chute 40 is provided in the middle of the assembly table 9 along its length direction. The PLC chute 40 is a structure arranged inside the strip hole formed after a strip hole is opened on the table surface of the assembly table 9. A PLC transfer frame 39 driven by a screw or belt transmission system for rotary reciprocating movement is provided in the PLC chute 40. Since the reciprocating mode of the screw structure will affect the material transmission of the entire assembly table 9, it is characterized in that it can only meet the assembly of a single PLC on the assembly table 9, so there is only the possibility of utilization and application. This embodiment is described as being able to reciprocate internally by a belt drive.

[0074] Reference Fig.16, the figure shows the structure of the PLC transfer rack 39 partially exposed from the PLC chute 40. The PLC transfer rack 39 is set up in an upward supporting manner, that is, it has four legs, and a placement area is formed by the four legs, and the PLC component 16 can be restricted inside for displacement. Since several PLC components 16 have different external dimensions, the legs on the PLC transfer rack 39 can be relatively displaced in pairs, so as to achieve size matching. A detection device specially used to identify the number of the PLC component 16 entering is provided in the feeding area 1, which can be identified by scanning the corresponding QR code, or by obtaining a picture through a visual sensor for identification. After identification, the size of the PLC component 16 entering can be confirmed, and then all subsequent disposal docking mechanisms will be adjusted in a manner adapted to the size of the PLC component 16.

[0075] The assembly table 9 is provided with a top plate installation station 33, a fin plate installation station and a side plate installation station in sequence along the extension direction of the PLC slide rail. Each station is provided with a corresponding material box for material supply. The material boxes are arranged on the outside of the assembly table 9 where the corresponding installation station is located, and corresponding transfer components are provided for material transfer.

[0076] Reference Fig.13 , the figure shows the assembly relationship of the top plate installation station 33 for installing the top plate. Among them, a top plate material box 15 outside the assembly table 9 is arranged in front of the top plate installation station 33. Figure 6 The top plate material box 15 is a container with a cylindrical inner wall of a larger volume, and its top is open, so that the amount of material can be seen from the outside and can be replenished at any time.

[0077] Fig.13 In the embodiment, a discharge port of the top plate is provided at the lower part of the top plate material box 15, and a belt-type top plate discharge belt 30 mechanism is provided at the discharge port, and the top plate discharge belt 30 is used to transport the top plate outward. A top plate lifting mechanism 31 is provided at the end of the top plate discharge belt 30, and the top plate is lifted to above the table surface of the assembly table 9 by the top plate lifting mechanism 31, and then the lifted top plate is transferred to the top plate installation station 33 by the top plate transverse moving frame 32 provided on the assembly table 9. At this time, the PLC component 16 moved by the PLC transfer frame 39 is fixed by the clamp of the top plate installation station 33, and then the top plate is transferred to the top of the PLC component 16 by the top plate transverse moving frame 32, and then it is installed in place by the components on the top plate installation station 33, completing the installation of the top plate.

[0078] Reference Figure 8, a fin board material box 18 for storing a plurality of fin boards is arranged on one side of the fin board installation station behind the top plate installation station 33. The structure of the fin board material box 18 is based on the principle of automatic upward pop-up of the clip type, and a plurality of fin boards are quantitatively pushed upward by the clip push block 19 structure with a spring arranged inside, so that there is always a fin board at the opening of the fin board material box 18 for easy grabbing. In this embodiment, three independent fin board material boxes 18 are arranged side by side, and a fin board conveying rack 17 is arranged between the fin board material box 18 and the fin board installation station, and the side fin boards are grabbed, lifted and transferred by the grabbing structure on the fin board conveying rack 17 that can move horizontally and can be lifted and lowered.

[0079] The fin box 18 in this embodiment has a vertically arranged material trough, in which a fin lifting frame 20 pushed by a spring is provided. A single fin lifting frame 20 corresponds to two material troughs, and a clip push block 19 is provided on the fin lifting frame 20 corresponding to each material trough, and the fin is pushed upward by the clip push block 19.

[0080] Reference Fig. 9 and Fig.16 A side panel material box is provided on one side of the side panel installation station behind the fin panel installation station, and a side panel installation frame 22 is provided between the side panel material box and the side panel installation station. The side panel installation frame 22 has two front and rear tracks, and each track is provided with a side panel installation flipping mechanism 21 that can move laterally. Fig. 9 and Fig.16 The figure shows two side panel installation flipping mechanisms 21 on both sides of the side panel installation frame 22, one of which holds the PLC component 16 and the other is in an empty state. The side panel installation flipping mechanism 21 has a rotating arm driven by a motor, and a clamping claw is provided at the bottom of the rotating arm. The PLC component 16 on the PLC transfer frame 39 is lifted by the clamping claw, rotated 180 degrees, and then put back into the side panel installation station to complete the installation of the side panels on both sides.

[0081] After the panel installation at the above three installation stations, the PLC component 16 has now formed a complete structure and is transferred by the second robot arm 6 arranged between the assembly area 2 and the small box packaging area 3.

[0082] Furthermore, two independent workbenches are provided in the small box assembly area 2 , wherein one of the workbenches is a small box packaging table 11 having a relatively long length, and the other is a small box preparation table 10 provided between the assembly area 2 and the small box packaging area 3 .

[0083] Reference Figure 2 , Figure 6 , Fig.10 , Fig.11 and Fig.14 , Figure 2 and Figure 6It can be seen that three independent small box material belts 38 are provided at the small box preparation table 10, and each small box material belt 38 is provided with a number of small packaging boxes 27 of corresponding sizes. The number of the PLC component 16 identified in the feeding area 1 determines its corresponding size, and then the small packaging box 27 on the corresponding delivery track is automatically selected for packaging through the mobile mechanism arranged at the small box preparation table 10.

[0084] Reference Fig.10 The front end of the small box preparation table 10 has a small box lateral movement frame 14 for lateral movement, and a small box moving mechanism 23 for reciprocating movement is provided on the small box lateral movement frame 14, and the small box moving mechanism 23 includes a lifting frame and an elastic adsorption mechanism arranged on the lifting frame. The small packaging boxes 27 stored on the distribution track in this embodiment are in a folded state, and the opening of the small packaging boxes 27 is propped open by the small box moving mechanism 23 to form a certain propped open state, and then the small packaging boxes 27 are transversely moved to the end of the small box conveyor belt 13 arranged on the small box packaging table 11, and the small packaging boxes 27 are fully propped open by the box propping mechanism 35 arranged at the end of the small box conveyor belt 13, so that the small packaging boxes 27 with the opening upward are at the end of the small box conveyor belt 13.

[0085] Reference Fig.14 In this embodiment, the end of the second mechanical arm 6 is rotatably connected to a clamping frame, on which a liftable suction cup mechanism and a clamping claw for clamping the PLC assembly 16 are provided; within the rotation coverage of the second mechanical arm 6, a spring-clip type book and disc material box 34 is provided, and the top of the book and disc material box 34 has two openings for separately supplying discs and instructions; the second mechanical arm 6 sequentially transfers the PLC assembly 16, the disc and the instruction to the same small packaging box 27 placed on the small packaging transmission line during one rotation. The second mechanical arm 6 keeps a reciprocating movement state, first rotating to the end of the assembly table 9, clamping and lifting the PLC assembly 16 with all the panels installed, and then rotating to sweep over the top of the book and disc material box 34 set at the angle between the assembly table 9 and the small box packaging table 11, and sucking the single instruction and the disc from the opening at the same time through the liftable suction cup mechanism set on one side, and then reaching the beginning of the small box conveyor belt 13. At this time, there is a small packaging box 27 that is unfolded and opened upward at the starting end. The gripper first places the PLC component 16 inside the small packaging box 27, and then the second robot arm 6 continues to rotate, and stacks the instruction manual and the disc on the top of the PLC component 16 in sequence, thereby completing a single operation.

[0086] An oblique slide rail is provided on one side of the book and plate material box 34. The oblique slide rail corresponds to the small box conveyor belt 13 and is used to send out unqualified small packaging boxes 27 or PLC components 16.

[0087] Reference Fig.14The back side of the small box conveyor belt is provided with a tongue plugging mechanism 36 and an ear folding mechanism 37 at the same position. The ear folding mechanism 37 corresponds to the ears on both sides of the small packaging box 27. The ear folding mechanism 37 is provided with two swing arms that can be closed toward the middle. The vertical ears are bent toward the middle by the two swing arms, and then the tongue plugging mechanism 36 at the back pushes the top cover plate to the bottom to cover the two ears to form a complete packaging state. The top cover of the small packaging box 27 is then glued and sealed by the sealing rolling mechanism 25 at the back, and finally the packaged small packaging box 27 is flipped backwards and falls out of the small box conveyor belt 13 through the flipping mechanism 26 at the end and the small box flipping fixture 24.

[0088] Furthermore, in the large box packaging area 4 of this embodiment, three large box conveyor belts 12 are arranged, and the large box conveyor belts 12 are multi-roller structures, and a bottom box 29 is arranged at the bottom of each large packaging box 28 for containing. Figure 6 , the outermost large box conveyor belt with several open large boxes 28 is used as an illustration. In the actual production process, open large boxes 28 are placed on the three large box conveyor belts. Then the third robot arm 7 takes the small boxes 27 from the small box conveyor belt 13 and matches the corresponding placement method according to the size of the corresponding small boxes 27, and places the small boxes 27 of the same specification in the same large box 28, and then packages them by the packaging mechanism on the large box conveyor belt 12.

[0089] It should be noted that there is an intelligent control module in the entire assembly and packaging system, that is, each PLC component 16 entering the system assembly line can be located. That is, the number of each PLC component 16 is obtained by the detection mechanism in the feeding area 1. The detection mechanism is generally arranged above the feeding track 8. By scanning the barcode pasted on the PLC component 16 for identification, the intelligent control module can obtain the specifications of the PLC component 16 through the system. CCD cameras are arranged at intervals on the conveying line of the entire system, and the entire conveying line is completely covered by the CCD cameras, and the picture information is transmitted to the intelligent control module in real time. CCD cameras for identification are also arranged on the first robotic arm 5, the second robotic arm 6 and the third robotic arm 7.

[0090] After the PLC component 16 is identified and numbered, the intelligent control module will immediately obtain the image of the PLC component 16 through the first CCD camera, and track and number the PLC component 16 through a box in the video data screen. Before all robotic arms clamp it, they will confirm the PLC component 16 through their own CCD cameras, and then the mechanism in the next process will adjust the clamping gap, the specifications of the small packaging box 27 and the internal placement of the large packaging box 28 according to the model of the PLC component 16.

[0091] In this embodiment, three large box conveyor belts 12 are arranged in the large box packaging area 4, but the large packaging boxes 28 on the large box conveyor belts 12 are all of the same specifications, and only the intelligent control module stores three placement methods of the large packaging boxes 28 for matching the three specifications of the small packaging boxes 27. This enables the entire system to simultaneously handle the PLC components 16 of different specifications that enter in disorder and then place them separately, with high flexibility and efficiency.

[0092] The present invention is not limited to the above optional implementations, and anyone can derive other various forms of products under the enlightenment of the present invention. The above specific implementations should not be understood as limiting the scope of protection of the present invention. The scope of protection of the present invention should be based on the definition in the claims, and the description can be used to interpret the claims.
