Description

Technical Field

[0001] This utility model relates to the field of robotic arm technology, specifically to a robotic arm for packaging box processing. Background Technology

[0002] Packaging boxes are indispensable containers in logistics, warehousing and commodity circulation. Their processing usually involves multiple steps, such as gripping and positioning the box blank, folding and forming the box body, pressing and pressing the edges of the cardboard, sealing or nailing with tape, and installing auxiliary parts (such as handles and labels). With the development of mechanical technology, packaging box processing has gradually shifted from manual operation to robotic arm operation.

[0003] Existing robotic arms for packaging box processing have multiple degrees of freedom. They control various electrical components on the robotic arm via a bus controller, which is connected to the electrical components via cables. Sensors and grippers are typically connected to the material gripping arm of the robotic arm, and these sensors and grippers are connected to the main controller via a cable. During the movement of the grippers on the material gripping arm, the cable follows the movement of the material gripping arm. This process can cause the cable to become tangled, which over time will affect the movement of the robotic arm and hinder its turning. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a robotic arm for packaging box processing.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The robotic arm for processing packaging boxes includes: A robotic arm device capable of transferring packaging box filler to a processing table, the robotic arm device including a connecting arm and a material moving arm disposed at the end of the connecting arm for gripping the packaging box filler; The auxiliary mechanism includes a main auxiliary device and a secondary auxiliary device respectively disposed on the side walls at both ends of the connecting arm. The auxiliary mechanism is used to support the cable and drive the cable to move. Both the main auxiliary device and the secondary auxiliary device include a guide rail for guiding the cable and a rotating rail for driving the cable to move. A traction device is located on one side of the robotic arm device. The traction device includes a guide seat, in which a reset component is provided. The guide seat includes a spring disposed in a channel, and a positioning seat is fixed to the end of the spring. The positioning seat can fix a part of the cable extension end. The traction device can cause the cable to be pulled upward and then reset downward.

[0006] Preferably, the main auxiliary device further includes a base plate on one side of the guide rail, a motor is fixed on one side of the base plate, the output end of the motor is connected to a connecting rod, and the end of the connecting rod is fixed to the rotating rail.

[0007] Preferably, the top of the rotating track has an arc-shaped placement groove facing downwards, and several suction cups are fixed in the placement groove.

[0008] Preferably, the reset assembly further includes a top plate fixed to the top of the spring, and the top plate is fixedly connected to the guide seat by bolts.

[0009] Preferably, the guide seat includes a first combined seat, a second combined seat, and a third combined seat. The first combined seat, the second combined seat, and the third combined seat are fixedly connected by bolts. The top of the first combined seat, the second combined seat, and the third combined seat are all provided with a groove facing downwards. After the first combined seat, the second combined seat, and the third combined seat are assembled, the groove forms a circular channel, and the spring and the positioning seat are located in the circular channel.

[0010] Preferably, the guide rail is symmetrically arranged with two arc-shaped plates, and the ends of the two arc-shaped plates are fixed with perforated plates, through which the cable can pass.

[0011] By setting an auxiliary mechanism on the outside of the robotic arm, the cable passes through the main auxiliary device and the auxiliary auxiliary device of the auxiliary mechanism. After the robotic arm pulls the cable during its operation, the main auxiliary device and the auxiliary auxiliary device reset the cable. A traction device is set at the extension end of the cable. The traction device, through the restriction of the spring and the positioning seat, allows the cable to be reset downward after being pulled upward. The cable will not become tangled due to the pulling of the robotic arm, which is conducive to the cable following the reasonable movement of the robotic arm, reducing the phenomenon of tangling, and allowing the robotic arm to continue to move at the work position without being obstructed by the cable.

[0015] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0016] This application provides a robotic arm for processing packaging boxes, including: a robotic arm device 300, an auxiliary mechanism, and a traction device 500. A conveyor table 600 is provided on one side of the robotic arm device 300, which conveys foam filler for supporting the interior of the packaging box. A processing table 200 is provided at one end of the conveyor table 600, and the top of the processing table 200 is used to place cardboard, which is then folded to form... Figure 1 The structure of the box 100 shown; Among them, such as Figure 1 and Figure 2 As shown: The robotic arm 300 can transfer the internal filler of the packaging box to the processing table 200 and place it on the cardboard on top of the processing table 200 (the processing table 200 is used to support the cardboard, on which foam filler is placed and folded to obtain the packaging box). The robotic arm device 300 includes a base 350 fixed to the ground. A rotating seat 340 is bolted to the top of the base 350. A swing arm 330 is mounted on the top of the rotating seat 340, and a rotatable connecting arm 310 is connected to its end. One end of the swing arm 330 can rotate with one side of the rotating seat 340 as the center point, so that the swing arm 330 can drive the connecting arm 310 to move in multiple positions. A material moving arm 320 for grasping the filling of the packaging box is mounted at the end of the connecting arm 310. It should be noted that the base 350 supports the rotating seat 340, and the bottom of the packaging rotating seat 340 will not move. The rotating seat 340 is used to drive the swing arm 330 to rotate. During the rotation of the swing arm 330, the connecting arm 310 and the material moving arm 320 can be driven to rotate, so that the material moving arm 320 can move the filling material to place the filling material on the cardboard on the top of the processing table 200. Among them, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, The auxiliary mechanism includes a main auxiliary device 400 and a secondary auxiliary device 410 respectively disposed on the side walls at both ends of the connecting arm 310. This auxiliary mechanism is used to support the cable 700 and drive the cable 700 to move. Both the main auxiliary device 400 and the secondary auxiliary device 410 include a guide rail 402 for guiding the cable 700 and a rotating rail 404 for driving the cable 700. The main auxiliary device 400 also includes a base plate 407 on one side of the guide rail 402. The base plate 407 is fixedly connected to the guide rail 402. A first mounting shell 311 is provided on the outer wall of one end of the connecting arm 310, and a second mounting shell 312 is provided on the outer wall of the other end. A fixing plate 401 is fixed on the outer wall of the second mounting shell 312. The end of the fixing plate 401 is fixedly connected to the guide rail 402 by bolts. The fixing plate 401 is used to position the main auxiliary device 400 to ensure the stability of the main auxiliary device 400 at the end of the connecting arm 310. A motor 408 is fixed on one side of the substrate 407. A connecting rod 405 is connected to the output end of the motor 408. The end of the connecting rod 405 is fixed to the rotating track 404. The output end of the motor 408 drives the connecting rod 405 to rotate, thereby driving the rotating track 404 to rotate. like Figure 4As shown, the top of the rotating track 404 is provided with an arc-shaped placement groove 406. The placement groove 406 is used to accommodate the cable 700 so that the cable 700 can contact the guide track 402. Several suction cups 409 are fixed in the placement groove 406. The suction cups 409 can adhere to the outer wall of the cable 700 to increase the friction between the cable 700 and the rotating track 404. During the rotation of the rotating track 404, the cable 700 can be driven to move. Among them, such as Figure 4 As shown, the guide rail 402 is symmetrically arranged with two arc-shaped plates, and the ends of the two arc-shaped plates are fixed with perforated plates 403, as shown. Figure 1 and Figure 2 As shown, the cable 700 can pass through the through hole of the perforated plate 403. The cable 700 extends through the through hole to the gap in the middle of the guide rail 402. At the same time, the cable 700 is also placed in the placement slot 406 of the rotating rail 404. The cable 700 continues to extend to the auxiliary device 410. The structure of the auxiliary device 410 is the same as that of the main auxiliary device 400. The extension end of the cable 700 passes through the through hole of the perforated plate 403 of the auxiliary device 410 and is then placed in the placement slot 406 of the rotating rail 404. The cable 700 continues to extend to the top of the material moving arm 320 and connects with the connector at the top of the material moving arm 320, thereby completing the connection of the cable 700.

[0017] Among them, such as Figure 2 , Figure 5 , Figure 8 As shown: The traction device 500 is located on one side of the robotic arm device 300. The traction device 500 includes a guide seat and a reset component 530 is provided in the guide seat. The reset component 530 can cause the cable 700 to be pulled upward and then reset downward. It should be noted that the reset assembly 530 includes a spring 533 disposed in the channel. A positioning seat 532 is fixed to the end of the spring 533. The positioning seat 532 can fix a part of the extension end of the cable 700. After the cable 700 passes through the central hole of the positioning seat 532, the part of the cable 700 located in the central hole of the positioning seat 532 is locked by bolts. When the cable 700 is pulled upward by an upward force, this part drives the positioning seat 532. The upward movement of the positioning seat 532 compresses the spring 533. The spring 533 is in a compressed state. When the tension disappears, the spring 533 automatically resets and springs the positioning seat 532 back to its original position. At this time, the cable 700 is also springed back to its original position. like Figure 7 and Figure 8As shown, the guide seat includes a first combination seat 510, a second combination seat 520, and a third combination seat 540. The first combination seat 510, the second combination seat 520, and the third combination seat 540 are fixedly connected by bolts. The top of the first combination seat 510, the second combination seat 520, and the third combination seat 540 are all provided with downward-facing grooves 511. After the first combination seat 510, the second combination seat 520, and the third combination seat 540 are assembled, the grooves 511 form a circular channel. The reset assembly 530 also includes a top plate 531 fixed to the top of the spring 533. The top plate 531 is fixedly connected to the guide seat by bolts to ensure the structural stability of the reset assembly 530 and to prevent the spring 533 from detaching from the guide seat due to the upward force of the cable 700. The spliced ​​structure of the first combination seat 510, the second combination seat 520, and the third combination seat 540 is conducive to the installation of the reset assembly 530 inside the guide seat.

[0018] It should be noted that one end of the cable 700 is connected to the bus controller (existing technology) of the robotic arm device 300, and the other end of the cable 700 passes through the guide seat of the traction device 500, then through the main auxiliary device 400 and the auxiliary auxiliary device 410, and finally connects to the material moving arm 320. During the operation of the robotic arm device 300, the material moving arm 320 drives the cable 700, and when the rotating seat 340 rotates, the cable 700 is also pulled by the movement of the connecting arm 310 and the swing arm 330. At this time, the output shaft of the motor 408 of the main auxiliary device 400 and the auxiliary auxiliary device 410 drives the connecting rod 405 to rotate, and drives the rotating track 404 to rotate. During the rotation of the rotating track 404, the cable 700 moves. The cable 700 moves in coordination with the movement of the robotic arm device 300, which is conducive to the active movement of the cable 700 and will not be pulled off. After the robotic arm device 300 resets, the output shaft of the motor 408 rotates in the opposite direction, driving the rotating track 404 to rotate in the opposite direction, thereby driving the cable 700 to return to its original state.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
