Description

Technical Field

[0001] This invention belongs to the field of foam packaging unpacking technology, and relates to a foam packaging unpacking clamp. Background Technology

[0002] Foam packaging offers advantages such as lightweight, impact resistance, and low cost, making it a popular choice for packaging many products in the manufacturing industry. Foam packaging is typically placed on top of and under the product. During warehouse stacking, the foam packaging and product can sometimes be compressed and interlocked due to gravity, as shown in the attached image. Figure 1 The diagram shows a stacked packaging method. However, when using robots to assemble products in production, each layer of foam packaging needs to be removed first. When using robots or transfer devices to move grippers to unpack the foam packaging, the robots or transfer devices move the grippers vertically upwards to grab the foam packaging. Some products may become embedded in the foam packaging, and due to the pulling force, the products are prone to tipping over or falling and being damaged. Summary of the Invention

[0004] To address the aforementioned problems, embodiments of the present invention provide a foam packaging unpacking clamp for unpacking foam packaging fitted onto a product. The foam packaging unpacking clamp includes a profile frame, a clamping mechanism, and a vibration mechanism. The clamping mechanism is located on opposite sides of the profile frame and is used to clamp the foam packaging. The vibration mechanism is located on the profile frame and is used to generate vibration to separate the foam packaging from the product.

[0006] In some embodiments, a vibrating plate is provided below the vibrator, and the upper end face of the vibrating plate is fixedly connected to the lower end face of the vibrator.

[0007] In some embodiments, the vibrating plate is elongated and extends to the clamping mechanisms on both sides of the profile frame.

[0008] In some embodiments, the first guide rod is provided with a first bushing, the outer ring of the first bushing is fitted into the limiting hole of the vibrator mounting plate, the first bushing is fixedly connected to the vibrator mounting plate, and the inner ring of the first bushing is fitted onto the first guide rod.

[0010] In some embodiments, a sensor mounting plate is provided on the profile frame, the sensor mounting plate is vertically fixed on the profile frame, the sensor mounting plate is provided with a vertical elongated mounting hole, and the proximity sensor is disposed in the mounting hole.

[0011] In some embodiments, a damping block is provided between the vibrator mounting plate and the profile frame.

[0012] In some embodiments, the clamping mechanism includes a clamping cylinder and a clamping plate.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0034] like Figures 2-4 As shown, this embodiment provides a foam packaging unpacking clamp for unpacking foam packaging 1 fitted onto product 2; the foam packaging unpacking clamp includes a profile frame 10, a clamping mechanism and a vibration mechanism 40; the clamping mechanism is located on opposite sides of the profile frame 10 and is used to clamp the foam packaging 1; the vibration mechanism 40 is located on the side of the profile frame 10 and is used to generate vibration to separate the foam packaging 1 from the product 2.

[0035] Specifically, in this embodiment, the foam packaging unpacking clamp has a profile frame 10 made of multiple profiles spliced ​​together. The profile frame 10 is rectangular in shape. Clamping mechanisms are provided on the short sides of both sides of the profile frame 10. The clamping mechanisms can clamp towards the middle. Vibration mechanisms 40 are provided on the two long sides of the profile frame 10. The vibration mechanisms 40 contact the upper surface of the foam packaging 1 and generate vibration, so that the foam packaging 1 is separated from the product 2.

[0036] like Figure 1 , Figure 4 As shown, the product 2 packaged by foam packaging 1 is generally placed on a wooden base tray 3. The foam packaging unpacking clamp with the above structure clamps the foam packaging 1 wrapped on the product 2 during unpacking. The clamping mechanism on the opposite sides of the profile frame 10 clamps the foam packaging 1. The vibration mechanism 40 on the side of the profile frame 10 can contact the foam packaging 1 when the clamping mechanism clamps the foam packaging 1. The vibration mechanism 40 can generate high-frequency vibration, which releases the adsorption stress generated by the gravity compression between the foam packaging 1 and the product 2 during the gripping process, so that the foam packaging 1 is separated from the product 2, preventing the product 2 from being damaged by adhering to the foam packaging 1.

[0037] like Figures 3-4 , Figures 8-11 As shown, in a specific embodiment, the vibration mechanism 40 includes a vibrator 41. The vibrator 41 has at least one first guide rod 42 in the vertical direction. One end of the first guide rod 42 is fixed to the vibrator 41. A spring 44 is sleeved on the first guide rod 42. A vibrator mounting plate 46 is provided on the first guide rod 42. The vibrator mounting plate 46 has a limiting hole. The first guide rod 42 is sleeved in the limiting hole, and the vibrator mounting plate 46 is located above the spring 44. The vibrator mounting plate 46 is fixedly connected to the profile frame 10. A top cap 45 for limiting is provided at the upper end of the first guide rod 42.

[0038] In this embodiment, vibration mechanisms 40 are respectively provided on the two long sides of the profile frame 10. Each vibration mechanism 40 is provided with a vibrator 41, and the vibrator 41 is provided with at least one first guide rod 42 in the vertical direction. Figure 2 , Figure 3In this embodiment, each vibrator 41 is provided with two first guide rods 42, which are vertically arranged on both sides of each vibrator 41. One end of the first guide rod 42 is fixedly connected to the vibrator 41. A spring 44 is sleeved on the first guide rod 42. A vibrator mounting plate 46 is provided above the first guide rod 42. The vibrator mounting plate 46 has a limiting hole and is sleeved on the first guide rod 42 to limit the spring 44 between the vibrator 41 and the vibrator mounting plate 46. The vibrator mounting plate 46 is fixedly connected to the profile frame 10. When unpacking foam packaging 1, the robotic arm controls the foam packaging unpacking clamp to move directly above foam packaging 1, and then moves downwards. The vibrator 41 contacts the upper surface of foam packaging 1. After receiving the upward thrust from foam packaging 1, the vibrator 41 moves upwards, compressing the spring 44 on the first guide rod 42. The clamping mechanisms on both sides clamp the foam packaging 1, and the vibrator 41 generates high-frequency vibration to separate foam packaging 1 from product 2. The robotic arm then drives the foam packaging unpacking clamp upwards, completing the unpacking of foam packaging 1. The vibrator 41 can be a pneumatic or electric vibrator. It vibrates when air or electricity is supplied, and the vibration frequency is adjustable. When releasing vibration, the vibrator 41, through the pressure provided by the spring 44, can more efficiently transmit the vibration force to foam packaging 1, releasing the stress caused by the pressure between foam packaging 1 and product 2. The top cap 45 can limit the downward stroke of the vibrator 41, so that when the vibrator 41 moves downward, the top cap 45 can abut against the vibrator mounting plate 46.

[0039] In a specific embodiment, a vibration plate 50 is provided below the vibrator 41, and the upper end face of the vibration plate 50 is fixedly connected to the lower end face of the vibrator 41.

[0040] The vibrating plate 50 is long and narrow, and extends to the clamping mechanisms on both sides of the profile frame 10.

[0041] In this embodiment, a vibration plate 50 is provided at the lower end of the vibrator 41. The long strip-shaped vibration plate 50 extends laterally to the clamping mechanism on both sides of the profile frame 10, which enables the high-frequency vibration generated by the vibrator 41 to be evenly transmitted to the upper surface of the foam packaging 1 through the vibration plate 50, so that the foam packaging 1 and the product 2 can be better separated and the unpacking efficiency can be improved.

[0042] In a specific embodiment, a first bushing 43 is provided on the first guide rod 42. The outer ring of the first bushing 43 is fitted into the limiting hole of the vibrator mounting plate 46. The first bushing 43 is fixedly connected to the vibrator mounting plate 46, and the inner ring of the first bushing 43 is fitted onto the first guide rod 42.

[0043] In this embodiment, a first bushing 43 is provided in the limiting hole of the vibrator 41, which enables the first guide rod 42 to move along the first bushing 43 when the vibrator 41 moves up or down, thereby obtaining a more stable motion effect.

[0044] In a specific embodiment, at least one cap 45 is provided with a sensing plate 48, and the profile frame 10 is provided with a proximity sensor 49 adapted to the sensing plate 48.

[0045] In this embodiment, when unpacking the foam packaging 1, the robotic arm controls the foam packaging unpacking clamp to move directly above the foam packaging 1, and then moves downward. The vibrator 41 contacts the upper surface of the foam packaging 1. After receiving the upward thrust from the foam packaging 1, the vibrator 41 moves upward, the first guide rod 42 moves upward, and the spring 44 on the first guide rod 42 is compressed. When the sensing plate 48 on the top cap 45 rises to a position close to the sensor 49, the robotic arm is controlled to stop moving downward, and the clamping mechanisms on both sides are controlled to clamp the sides of the foam packaging 1. At the same time, the vibrator 41 generates high-frequency vibration to separate the foam packaging 1 from the product 2. The robotic arm drives the foam packaging unpacking clamp to move upward, completing the unpacking of the foam packaging 1.

[0046] In a specific embodiment, a sensor mounting plate 491 is provided on the profile frame 10. The sensor mounting plate 491 is vertically fixed on the profile frame 10. The sensor mounting plate 491 is provided with mounting holes, and the proximity sensor 49 is horizontally installed in the mounting holes.

[0047] The mounting holes of the sensor mounting plate 491 are vertically elongated, and the two ends of the proximity sensor 49 are respectively provided with a first locking nut 492 and a second locking nut 493.

[0048] In this embodiment, the proximity sensor 49 passes through the mounting hole of the sensor mounting plate 491. Both ends of the proximity sensor 49 are locked in place by a first locking nut 492 and a second locking nut 493, allowing its position to be adjusted up and down through the vertically elongated mounting hole. By cooperating with the sensing plate 48, the clamping height setting and the pressure between the vibration mechanism 40 and the foam packaging 1 can be quickly adjusted.

[0049] In a specific embodiment, a damping block 47 is provided between the vibrator mounting plate 46 and the profile frame 10.

[0050] In this embodiment, a damping block 47 is sandwiched between the vibrator mounting plate 46 and the profile frame 10 to reduce the transmission of vibration to the profile frame 10 and maintain the stability of the profile frame 10.

[0051] like Figures 3-7As shown, in a specific embodiment, the clamping mechanism includes a clamping cylinder 20 and a clamping plate 30. The clamping cylinder 20 is horizontally fixed on the profile frame 10, and the output shaft 21 of the clamping cylinder 20 faces the outside of the profile frame 10. The output shaft 21 of the clamping cylinder 20 is vertically fixedly connected to the clamping plate 30.

[0052] In this embodiment, clamping cylinders 20 are respectively provided on both sides of the profile frame 10. The output shaft 21 of the clamping cylinder 20 faces the outside of the profile frame 10, and the output shaft 21 of the clamping cylinder 20 is vertically connected to the clamping plate 30. When the output shaft 21 of the clamping cylinder 20 retracts and extends, it drives the clamping plate 30 to open and close, thereby clamping and releasing the foam packaging 1. The retraction and extension stroke of the clamping cylinder 20 is relatively large, which can accommodate the clamping of foam packaging 1 of various sizes and specifications, and can improve production efficiency when unpacking foam packaging 1 of different specifications.

[0053] In a specific embodiment, the lower edge of the clamping plate 30 is provided with a hook 31 facing the inside of the profile frame 10.

[0054] In this embodiment, multiple gripping hooks 31 can be provided at intervals or one long strip gripping hook 31 can be provided along the lower edge of the clamping plate 30. The gripping hooks 31 are used to prevent the foam packaging 1 from falling off during clamping.

[0055] In a specific embodiment, the profile frame 10 is provided with a cylinder mounting plate 22, and the clamping cylinder 20 is fixed on the cylinder mounting plate 22.

[0056] In this embodiment, there are two cylinder mounting plates 22, which are respectively laid on both sides of the profile frame 10, and the cylinder mounting plates 22 are fixedly connected to the profile frame 10; the clamping cylinder 20 is fixed on the cylinder mounting plate 22.

[0057] In a specific embodiment, a second bushing 23 is provided on the cylinder mounting plate 22, and a second guide rod 24 is sleeved on the second bushing 23. One end of the second guide rod 24 is vertically and fixedly connected to the clamping plate 30.

[0058] In this embodiment, the second bushing 23 is disposed on the cylinder mounting plate 22, and the second guide rod 24 is sleeved inside the second bushing 23. One end of the second guide rod 24 is fixedly connected to the clamping plate 30, which makes the clamping plate 30 more stable when the output shaft 21 of the clamping cylinder 20 retracts and extends.

[0059] In a specific embodiment, a clamp mounting plate 11 is provided at the middle position of the profile frame 10.

[0060] In this embodiment, the clamp mounting plate 11 is located in the middle of the profile frame 10 and is used to mount the foam packaging unpacking clamp on the robotic arm. The robotic arm is used to control the vertical and horizontal movement of the foam packaging unpacking clamp.

[0061] In a specific embodiment, the profile frame 10 is composed of at least two horizontal profiles and two vertical profiles spliced ​​together.

[0062] In this embodiment, two horizontal profiles and two vertical profiles are spliced ​​together to form a rectangular frame. The profile frame 10 is preferably made of aluminum. The profile frame 10 is used to support the clamping mechanism and the vibration mechanism 40. A clamp mounting plate 11 is provided in the middle position of the profile frame 10. The entire foam packaging unpacking clamp can be fixed to the robotic arm through the clamp mounting plate 11 to realize the motion control of unpacking.

[0063] In summary, during operation, the output shaft 21 of the clamping cylinder 20 extends, and the robotic arm controls the foam packaging unpacking fixture to move downwards to clamp the foam package 1. The vibrating plate 50 first contacts the upper surface of the foam package 1. As it continues to move downwards, the vibrating plate 50 receives the supporting force from the foam package 1 and moves upwards through the first guide rod 42. During this movement, the sensing plate 48 on the first guide rod 42 also moves upwards, gradually reaching the detection range of the proximity sensor 49. The proximity sensor 49 outputs a signal, stopping the downward movement, and the output shaft 21 of the clamping cylinder 20 retracts to clamp the foam package 1. Next, the foam packaging unpacking fixture moves upwards a small distance and then pauses for a short time, allowing the foam package 1 and product 2 a gap and time to separate. At the same time, the vibrator 41 outputs vibration to the foam package 1 through the vibrating plate 50. Then, the foam packaging unpacking fixture continues to move upwards and shuts off the output of the vibrator 41, removing the foam package 1. After unpacking and placing the foam package 1, the single unpacking is completed.

[0064] In actual operation, the robotic arm can quickly change grippers via a quick-change disc, and simultaneously perform unpacking and product installation. This eliminates the need for manual unpacking of foam packaging, saving manpower, achieving full automation and unmanned operation, and improving production efficiency and product quality.

[0065] In summary, it is readily understood by those skilled in the art that, without conflict, the aforementioned advantageous technical features can be freely combined and superimposed.

[0066] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention shall still fall within the scope of the technical solution of the present invention.
