DETAILED DESCRIPTION

[0038] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0039] It can be understood that the terms "first", "second", etc. used in the present application can be used in this article to describe various elements, but unless otherwise specified, these elements are not limited by these terms. These terms are only used to distinguish the first element from another element.

[0040] like Figure 1 , Figure 4 , Figure 6 , Figure 8 and Figure 9 As shown, in one embodiment, an efficient unpacking device for packaging is proposed, the device comprising:

[0041] Suction cup holder 1: It includes a mounting table 101 provided on the suction cup holder 1;

[0042] Wiping mechanism 2: It includes a wiping wheel 201 installed on the mounting table 101, and an air outlet cylinder 202 is rotatably connected to the inner wall of the wiping wheel 201;

[0043] Rotating mechanism 3: It is used to drive the wiping wheel 201 to perform a semi-circular arc movement to wipe the surface of the packaging box;

[0044] Chute mechanism 4: It is used to drive the wiping wheel 201 to always fit the surface of the packaging box;

[0045] Dialing device 5: It is used to drive the rotating mechanism 3 to adjust the extrusion pressure with the packaging box;

[0046] Negative pressure mechanism 7: It is used to generate negative pressure to adsorb the surface of the packaging box.

[0047] In the actual application of the embodiment of the present invention, when performing the unpacking operation of the packaging box, at this time, the mounting table 101 approaches the surface of the packaging box under the drive of an external device. At this time, under the action of the rotating mechanism 3, the wiping wheel 201 is driven to perform a semi-circular motion. At the same time, through the cooperation of the dialing device 5 and the chute mechanism 4, when the wiping wheel 201 presses on the surface of the packaging box, the extrusion pressure remains unchanged, thereby avoiding damage to the surface of the packaging box caused by excessive extrusion pressure. Under the action of the rotating mechanism 3, the wiping wheel 201 wipes the surface of the packaging box, thereby wiping off the impurities at the adsorption position on the surface of the packaging box, avoiding affecting the vacuum degree of adsorbing the surface of the packaging box and causing the problem of unpacking failure. At the same time, under the action of the negative pressure mechanism 7, air flow is output through the air outlet cylinder 202 to blow off the dust on the surface of the packaging box, increasing the adsorption firmness and avoiding the problem of blockage caused by the accumulation of dust on the suction cup. After completion, the surface of the packaging box is adsorbed through the negative pressure mechanism 7 without affecting the unpacking operation.

[0048] As Figure 8 and Figure 9 shown, as a preferred embodiment of the present invention, the rotating mechanism 3 includes a connecting column 301 fixedly installed on the surface of the air outlet cylinder 202. One end of the connecting column 301 away from the air outlet cylinder 202 is fixedly installed with a sliding column 302. The sliding column 302 is connected to a fixed cylinder 304 through a compression spring 303. The sliding column 302 is slidably connected to the fixed cylinder 304. The surface of the fixed cylinder 304 is fixedly installed on a rotating cylinder 305. The rotating cylinder 305 penetrates through the mounting table 101 and is rotatably connected to the mounting table 101.

[0049] When the embodiment of the present invention is actually used, through the action of the slide groove mechanism 4, the rotation of the rotating cylinder 305 causes the sliding column 302 to move along the trajectory of the slide groove mechanism 4 through the toggle device 5. At this time, the sliding column 302 slides in the fixed cylinder 304, and the sliding column 302 drives the exhaust cylinder 202 to move synchronously through the connecting column 301, thereby driving the wiping wheel 201 to wipe the surface of the packaging box, thereby ensuring the uniformity of the wiping force and avoiding damage to the surface of the packaging box.

[0050] like Figure 3 and Figure 14 As shown, as another preferred embodiment of the present invention, the slide mechanism 4 includes a lifting platform 405 fixedly mounted on the mounting platform 101, the lifting platform 405 is provided with a first equal-diameter groove 401, the lifting platform 405 is provided with a contraction groove 402, the lifting platform 405 is provided with a second equal-diameter groove 403, the lifting platform 405 is provided with a reset groove 404, and the first equal-diameter groove 401, the contraction groove 402, the second equal-diameter groove 403 and the reset groove 404 are connected in sequence, a group of lifting platforms 405 are arranged opposite to each other in a circular array, and an arc-shaped boss is provided at the end of the reset groove 404.

[0051] In practical application of the embodiment of the present invention, when the rotating mechanism 3 drives the wiping mechanism 2 to rotate, Figure 3 As shown, at this time, under the action of the slide mechanism 4, the toggle device 5 moves along the track of the slide mechanism 4. When the device moves toward the packaging box, as shown in FIG. Figure 14 As shown, at this time, under the action of the first equal-diameter groove 401, the sliding column 302 will not move in the fixed cylinder 304. When it moves to the contraction groove 402, the wiping wheel 201 has been squeezed to the surface of the packaging box. As the device approaches the packaging box, the trajectory radius of the contraction groove 402 gradually decreases. At this time, the sliding column 302 shrinks inward along the fixed cylinder 304, so that the wiping wheel 201 always maintains contact pressure with the packaging box. When it moves to the second equal-diameter groove 403, since the wiping wheel 201 completes half of the semi-circle movement at this time, when the wiping wheel 201 moves along the packaging box, since the device continues to approach the packaging box, the sliding column 302 will not slide in the fixed cylinder 304. After moving out of the adsorption range, the wiping wheel 201 no longer squeezes the packaging box. At this time, it moves to the reset groove 404, and the sliding column 302 extends out of the fixed cylinder 304 for reset, thereby achieving an automatic adjustment of the movement state, ensuring that the squeezing force of the wiping wheel 201 and the packaging box is consistent.

[0052] like Figure 8 , Figure 11 and Figure 14As shown, as another preferred embodiment of the present invention, the toggle device 5 includes two toggle rods 501 fixedly mounted on the surface of the sliding column 302, each toggle rod 501 is rotatably connected to a sliding ball 502, the sliding ball 502 contacts the inner wall of the lifting platform 405, the surface of the toggle rod 501 is slidably connected to a linkage rod 503, the surface of the linkage rod 503 is rotatably connected to a sliding rod 504, one end of the sliding rod 504 away from the linkage rod 503 is slidably connected to the surface of the fixed cylinder 304, the sliding rod 504 is connected to the surface of the linkage rod 503 through a toggle spring 505, the surface of the linkage rod 503 is rotatably connected to a swing rod 506, one end of the swing rod 506 away from the linkage rod 503 is rotatably connected to the surface of the fixed cylinder 304, one end of the linkage rod 503 away from the toggle rod 501 is slidably connected to the other toggle rod 501 at the symmetrical end, and the linkage rod 503 is slidably connected to the inner wall of the fixed cylinder 304.

[0053] In actual application of the embodiment of the present invention, when the rotating cylinder 305 drives the wiping wheel 201 to move, Figure 8 As shown, at this time, the sliding column 302 drives the toggle rod 501 to move along the slide groove mechanism 4. The sliding ball 502 provided on the toggle rod 501 is used to reduce the friction during the movement process and increase the service life of the device. When the toggle rod 501 moves to the end of the lifting platform 405, as shown in FIG. Figure 14 and Figure 11 As shown, at this time, the sliding ball 502 drives the linkage rod 503 to move toward the central axis of the fixed cylinder 304 through the toggle rod 501 at the arc-shaped boss at the end of the lifting platform 405. The sliding connection between the linkage rod 503 and the toggle rod 501 is to prevent the toggle rod 501 from interfering with the position of the linkage rod 503 when the toggle rod 501 moves in the vertical direction. The movement of the linkage rod 503 drives the sliding rod 504 and the swing rod 506 to swing. The sliding rod 504 slides along the fixed cylinder 304 synchronously and compresses the toggle spring 505 at the same time. When the sliding ball 502 moves to the top of the boss, the swing limit of the sliding rod 504 is reached, so that the sliding rod 504 is driven to swing to the other end under the action of the toggle spring 505. Figure 8 As shown, at this time, the sliding ball 502 at the symmetrical end is driven to move to the left to contact the slide groove mechanism 4, and the slide groove mechanisms 4 at both ends are arranged in a circular opposition, and can perform up and down circular wiping movements, thereby achieving the purpose of automatic switching, facilitating the next adsorption of the packaging box to repeat the same wiping movement, reducing the waste of resetting movements, and improving the movement efficiency of the device.

[0054] like Figure 5As shown, as another preferred embodiment of the present invention, the device further includes a driving device 6. The driving device 6 includes a driving motor 601 fixedly installed on the mounting table 101. Two driving gears 602 are fixedly installed at the output end of the driving motor 601. Each driving gear 602 meshes with a rotating gear 603. The surface of the rotating gear 603 is coaxially and fixedly connected to the rotating cylinder 305.

[0055] In the actual application of the embodiment of the present invention, when it is necessary to adsorb the packaging box, when the mounting table 101 approaches the packaging box under the action of an external drive, as Figure 5 shown, at this time, the driving motor 601 starts to operate. The driving motor 601 drives the driving gear 602 to rotate through its output end. The rotation of the driving gear 602 drives the rotating gear 603 to rotate synchronously through the meshing action with the rotating gear 603. At this time, the rotating gear 603 drives the rotating cylinder 305 to rotate, and then drives the wiping wheel 201 to perform a semi-circular arc movement, so as to achieve the purpose of wiping the surface of the adsorption position of the packaging box.

[0056] As Figure 3 、 Figure 4 、 Figure 6 、 Figure 8 and Figure 9 shown, as another preferred embodiment of the present invention, the negative pressure mechanism 7 includes an air inlet 701 installed on the mounting table 101. The air inlet 701 is fixedly installed on the air flow block 702. A negative pressure hole 703 is provided inside the air flow block 702. Two conveying pipes 704 are fixedly installed on the surface of the air flow block 702. One end of each conveying pipe 704 away from the air flow block 702 penetrates through the mounting table 101, and the conveying pipe 704 is rotationally connected to the rotating cylinder 305. A negative pressure suction cup 705 is fixedly installed on the surface of the air flow block 702. The negative pressure suction cup 705 penetrates through the mounting table 101 and is slidably connected to the mounting table 101. The negative pressure suction cup 705 is connected to the mounting table 101 through a suction cup spring 706. The negative pressure hole 703 is communicated with the inside of the negative pressure suction cup 705.

[0057] In the actual application of the embodiment of the present invention, when the device is working, as Figure 6 shown, at this time, compressed air is input through the air inlet 701. At this time, the compressed air enters the air flow block 702. Since the negative pressure hole 703 is perpendicular to the main channel of the air flow block 702, a negative pressure is formed at the position of the negative pressure hole 703, as Figure 6 and Figure 8 shown. And the main channel air flow of the air flow block 702 enters the rotating cylinder 305 through the conveying pipe 704. The conveying pipe 704 is set as a flexible pipe, so that the movement of the air flow block 702 will not affect the air flow transmission, as Figure 3 and Figure 9As shown, the airflow in the rotating cylinder 305 enters the air outlet cylinder 202 through the fixed cylinder 304, the sliding column 302, and the connecting column 301. At this time, the airflow is blown out through the circular hole set in the sliding column 302, so that the dust at the adsorption position of the packaging box is blown away during the movement of the wiping wheel 201 to avoid affecting the adsorption vacuum degree. Figure 4 As shown, the negative pressure generated by the negative pressure hole 703 simultaneously generates negative pressure at the position of the negative pressure suction cup 705, so that the purpose of adsorbing the packaging box is achieved through the negative pressure suction cup 705.

[0058] like Figure 9 , Figure 12 and Figure 13 As shown, as another preferred embodiment of the present invention, the device also includes a switching mechanism 8, which includes a switching gear cylinder 801 coaxially fixedly mounted on the surface of the wiping wheel 201, a rotating chain 802 is sleeved on the surface of the switching gear cylinder 801, and one end of the rotating chain 802 away from the switching gear cylinder 801 is sleeved on the synchronous gear 803, and a movable ratchet gear 804 is coaxially fixedly mounted on the surface of the synchronous gear 803, and the movable ratchet gear 804 is meshed with a fixed rack 805, and the fixed rack 805 is fixedly mounted on the fixed cylinder 304.

[0059] In actual application of the embodiment of the present invention, when the toggle rod 501 is reset through the reset groove 404, as shown in FIG. Figure 9 As shown, from Figure 9 From the front view, the toggle rod 501 drives the sliding column 302 to move downward. Figure 12 As shown, from Figure 12 The movable ratchet gear 804 is driven to move downwards from the front view direction. At this time, the movable ratchet gear 804 rotates under the meshing action of the movable ratchet gear 804 and the fixed rack 805. Due to the ratchet setting of the movable ratchet gear 804, the movable ratchet gear 804 will not rotate when following the upward movement of the sliding column 302. The rotation of the movable ratchet gear 804 drives the synchronous gear 803 to rotate. The synchronous gear 803 drives the switching gear cylinder 801 to rotate through the rotating chain 802. The rotation of the switching gear cylinder 801 drives the wiping wheel 201 to rotate 180 degrees. Figure 13 As shown, at this time, the wiping position of the wiping wheel 201 is exactly on the air outlet of the air outlet tube 202. Since the wiping wheel 201 is made of breathable material, the airflow will blow away the impurities wiped on the wiping wheel 201, and each adsorption cycle will be switched to automatically clean the wiping wheel 201 to avoid affecting the next wiping.

For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as falling within the scope described in this specification.
