Description

Technical Field

[0001] This utility model relates to the field of automated packaging technology, and in particular to a suction cup suction mechanism for an automatic cable tie cutting device. Background Technology

[0002] To facilitate the transportation of goods such as pharmaceuticals, tobacco, and small appliances, packaging boxes are needed to protect them from damage during transport. Current semi-automatic packaging lines still require manual loading, which can easily lead to incorrect box orientation or the use of the wrong box, requiring rework and increasing production costs. Therefore, many companies are starting to use robotic arms that use suction cups to transfer cartons from pallets to a conveyor belt. For example, Chinese patent application number 202421399470.5 discloses a vacuum suction cup robotic arm with positioning function, including a fixing bolt, a transport unit on one side of the fixing bolt, a rotating unit inside the transport unit, and a suction unit inside the rotating unit. The rotating unit includes a moving plate located inside the transport unit. The vacuum suction cups of this device are mounted on an H-shaped support. This type of support has poor bending resistance and is only suitable for picking up lighter items. However, cardboard boxes are usually bundled and are quite heavy. When using the suction cup picking mechanism of this solution to pick up the boxes, sudden stops or rotations can easily cause the support to deform. In addition to picking up the boxes, bundled cardboard boxes also require an automatic cable tie cutter to cut and remove the cable ties. The H-shaped support structure is too compact and does not provide enough space for the automatic cable tie cutter to be installed. Furthermore, cardboard boxes are usually not flat on the pallet, and the suction cups of this device are fixed in the middle. If the suction cups and cardboard boxes are not tightly attached, air can easily leak between them, and the cardboard boxes can easily fall off during the picking process. Therefore, a suction cup picking mechanism for an automatic cable tie cutter is needed. This mechanism has a high structural strength, which facilitates the installation of the automatic cable tie cutter. Moreover, the suction cups can be floating on the support, allowing them to fit more closely to the cardboard boxes during picking and making it easier for the suction cups to adhere to the boxes. Utility Model Content

[0003] To address the aforementioned issues, this invention proposes a suction cup mechanism for an automatic cable tie cutting device. The support structure is strong, facilitating the installation of the automatic cable tie cutting device. Furthermore, the suction cup can be floating on the support, allowing it to fit more closely to the cardboard box during loading, making it easier for the suction cup to adhere to the cardboard box.

[0004] This utility model is achieved through the following technical solution: This utility model proposes a suction cup suction mechanism for an automatic cable tie cutting device, comprising: a bracket, a suction cup, and a mounting plate. The bracket has a rectangular frame on its outer side, a crossbar in the middle of the rectangular frame, and diagonal bars on both sides of the crossbar. One end of the diagonal bar is connected to the middle of the crossbar, and the other end of the diagonal bar is connected to the corner of the rectangular frame. The middle of the crossbar is connected to a feeding robot through a first connecting pipe. The suction cup has a second connecting pipe, which is slidably mounted on the rectangular frame. There are two mounting plates, which are respectively mounted on the rectangular frame and the lower part of the crossbar through connecting blocks.

[0005] Furthermore, the rectangular frame is provided with a guide tube, which is fixed to the tube wall of the rectangular frame by a nut. The second connecting tube passes through the middle of the guide tube, and a spring is provided between the second connecting tube and the guide tube.

[0006] Furthermore, one end of the second connecting pipe is provided with a connector, and a solenoid valve and a vacuum generator are provided on the bracket. The air inlet of the solenoid valve is connected to a high-pressure gas source, and the air outlet of the solenoid valve is connected in parallel with the connector on the second connecting pipe through the vacuum generator.

[0007] Furthermore, the support is equipped with a pressure gauge, which is connected to a solenoid valve via a conduit.

[0008] Furthermore, the connecting block has threaded holes on both sides, and each mounting plate has 2 to 4 connecting blocks. The connecting blocks are connected to the mounting plate, rectangular frame and crossbar by nuts.

[0009] Furthermore, the mounting plate is parallel to the rectangular frame, and the height of the mounting plate is 2cm to 4cm higher than the height of the suction cup.

[0010] Furthermore, triangular reinforcing plates are provided at the corners of the rectangular frame and at the connection points between the crossbar and the rectangular frame.

[0011] The beneficial effects of this utility model are as follows: By setting horizontal and diagonal bars in the middle of the rectangular frame, the overall rigidity of the rectangular frame is increased, which can prevent the support from bending and deforming when feeding cartons. At the same time, the rectangular frame and horizontal bars can provide installation positions for fixing the mounting plate, so as to facilitate the installation of the automatic cable tie cutting device. Furthermore, the suction cup can be floatingly installed on the rectangular frame, which makes it easier for the suction cup to adhere to the cartons during feeding and prevents the cartons from falling off.

[0016] like Figure 1 , Figure 2 , Figure 3 As shown, an embodiment of this utility model provides a suction cup suction mechanism for an automatic cable tie cutting device, including: a bracket 1, a suction cup 2, and a mounting plate 3. A rectangular frame 4 is provided on the outer side of the bracket 1. A crossbar 5 is provided in the middle of the rectangular frame 4, and diagonal bars 6 are provided on both sides of the crossbar. One end of the diagonal bar 6 is connected to the middle of the crossbar 5, and the other end of the diagonal bar 6 is connected to the corner of the rectangular frame 4. The middle of the crossbar 5 is connected to a feeding robot through a first connecting pipe 7. A second connecting pipe 8 is provided on the suction cup 2, and the second connecting pipe 8 is slidably installed on the rectangular frame 4. There are two mounting plates 3, which are respectively installed on the lower part of the rectangular frame 4 and the crossbar 5 through connecting blocks 9.

[0017] During automatic feeding, the position information of the cartons on the pallet is first obtained through 2D photography and 3D scanning to determine the gripping position. Then, the feeding robot moves the bracket 1 to the top of the cartons on the pallet and slowly descends, so that the suction cup 2 is attached to the top surface of the bundled cartons. Then, the solenoid valve 12 is opened, and the vacuum generator 13 generates negative pressure, so that the suction cup 2 obtains suction force and firmly adheres to the top of the cartons. Then, the automatic cable tie cutting device installed on the mounting plate 3 moves to both sides and hooks the cable ties on the cartons. After the above actions are completed, the robot moves, driving the cartons to the top of the carton conveyor belt. The automatic cable tie cutting device cuts the cable ties, and the robot pulls the cable ties off the cartons, completing the automatic feeding work.

[0018] The rectangular frame 4 is structurally reinforced by the crossbars 5 and diagonal bars 6. During loading, when the robot arm stops or rotates suddenly, it can prevent the support 1 from twisting and deforming, thus preventing the carton from falling. The rectangular frame 4 and the crossbars 5 can provide installation positions, so that the mounting plate 3 can be stably fixed to the support 1 by the connecting block 9. This facilitates the installation of the automatic cable tie cutting device on the suction cup suction mechanism, so that it can work together with the suction cup suction mechanism to complete a series of carton loading actions.

[0019] There are four suction cups 2, which are installed at the four corners of the rectangular frame 4. The suction cups 2 and the second connecting tube 8 can move linearly relative to the bracket 1. When the bracket 1 cannot be flush with the top surface of the carton, or when the carton itself is bent too much, the four suction cups can still fit against the top surface of the carton, improving the success rate of suction and reducing the probability of shutdown alarm.

[0020] In a preferred embodiment, such as Figure 3 As shown, a guide tube 10 is provided on the rectangular frame 4. The guide tube 10 is fixed to the tube wall of the rectangular frame 4 by a nut. The second connecting tube 8 passes through the middle of the guide tube 10, and a spring 11 is provided between the second connecting tube 8 and the guide tube 10. The suction cup 2 and the second connecting tube 8 can slide in a straight line in the guide tube 10. They can float during feeding, so that they fit the upper surface of the carton better during feeding, thereby improving the success rate of picking up the carton.

[0021] Specifically, one end of the second connecting pipe 8 is provided with a connector, and the bracket 1 is provided with a solenoid valve 12 and a vacuum generator 13. The air inlet of the solenoid valve 12 is connected to a high-pressure air source, and the air outlet of the solenoid valve 12 is connected in parallel with the connector on the second connecting pipe 8 through the vacuum generator 13. After the solenoid valve 12 is opened, the high-pressure air generates negative pressure through the vacuum generator, and then sucks the air in the suction cup 2, so that the bundled cardboard boxes can be sucked up, which facilitates the loading operation.

[0022] Specifically, the support 1 is equipped with a pressure gauge 14, which is connected to the solenoid valve 12 through a conduit to obtain air pressure information so as to ensure that the suction cup can firmly hold the carton.

[0023] Preferably, the connecting block 9 has threaded holes on both sides, and each mounting plate 3 has 2 to 4 connecting blocks 9. The connecting blocks 9 are connected to the mounting plate 3, the rectangular frame 4 and the crossbar 5 by nuts, so that the connecting blocks 9 can be fixed between the suction cups to provide an installation position, which facilitates the installation of the automatic cable tie cutting device. Multiple connecting blocks 9 can improve the stability of the mounting plate 3.

[0024] Specifically, the mounting plate 3 is parallel to the rectangular frame 4, and the height of the mounting plate 3 is 2cm to 4cm higher than the height of the suction cup 2. When the bracket 1 is close to the carton, the suction cup 2 can first contact and suck up the carton, which can prevent the carton from moving when hooking the cable tie. After sucking up the carton, the automatic cable tie cutting device moves again to hook the cable tie.

[0025] In one specific embodiment, triangular reinforcing plates 15 are provided at the corners of the rectangular frame 4 and at the connection points between the crossbar 5 and the rectangular frame 4. The triangular reinforcing plates 15 can further improve the structural strength of the entire support 1, maintain stability when picking up heavy cartons, and improve the reliability and service life of the entire suction cup picking mechanism.

[0026] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
