Description

Technical Field

[0001] This utility model relates to the field of packaging machinery and equipment technology, specifically to an MNT bagging mechanism. Background Technology

[0002] MNT is an abbreviation for "Monitor," referring to the core component used for image display in various electronic devices, including computer monitors, television screens, smart interactive screens, and in-vehicle display terminals. As precision electronic components, their surfaces are easily affected by bumps, scratches, or dust contamination. Therefore, they need to be bagged and sealed after production to ensure the product's condition during warehousing, transportation, and turnover.

[0003] For example, CN208906804U discloses an automatic screen bagging machine, which includes a chassis, an electrical control box on one side of the chassis, a screen feeding conveyor belt inside the chassis, a screen gripping mechanism on one side of the screen feeding conveyor belt, a finished product output belt on the other side of the screen feeding conveyor belt, a protective bag feeding mechanism on the front side of the screen feeding conveyor belt, a protective bag gripping mechanism on top of the screen feeding conveyor belt, and a touch control panel on the top surface of the chassis.

[0004] The aforementioned automatic screen bagging machine still has certain limitations. According to its description, after the screen is placed inside the protective bag, the protective bag gripping mechanism adjusts the vacuum level of the vacuum conveying pipe connected to the protective bag suction cup, causing the suction cup to increase suction force and lift the protective bag containing the screen, transferring it to the finished product output belt. During this process, the lack of effective restraint at the opening of the protective bag can easily lead to an excessively large opening, causing the protective bag to interfere with other parts of the equipment during movement, thus hindering its movement.

Detailed Implementation

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0026] One embodiment of the MNT bagging mechanism, such as Figure 1 As shown, the device includes a screen conveying device 1, a bag feeding device 2, a bag loading device 3, and a bag opening device 4. Screen conveying devices 5 are respectively located below the screen conveying device 1 and the bag opening device 4. In use, the bag loading device 3 transports the bag from the bag feeding device 2 to the screen conveying device 5 below the bag opening device 4. Then, the bag opening device 4 opens the bag, and the screen conveying device 1 picks up the screen placed below it and places it into the open bag. Finally, the packaged screen is output through the screen conveying device 5 below the bag opening device 4.

[0027] Combination Figure 2 and Figure 3As shown, the screen transport device 1 includes a screen transport mounting frame 10, a first X-axis drive mechanism 12, and a screen transport arm 11. The first X-axis drive mechanism 12 is fixedly mounted on the top of the screen transport mounting frame 10, and the screen transport arm 11 is slidably mounted on the top of the screen transport mounting frame 10. The first X-axis drive mechanism 12 is connected to the screen transport arm 11 for driving the screen transport arm 11 to move along the X-axis direction.

[0028] The screen handling arm 11 includes a first crossbeam 110, a first Z-axis drive mechanism 111, a first truss 112, and screen suction nozzles 113. The first crossbeam 110 is slidably connected to the top of the screen handling mounting frame 10. The first Z-axis drive mechanism 111 is fixedly connected to the first crossbeam 110. The end of the first truss 112 is fixedly connected to the bottom of the first Z-axis drive mechanism 111. The first Z-axis drive mechanism 111 drives the first truss 112 to move along the Z-axis. Multiple screen suction nozzles 113 are fixedly mounted on the first truss 112, with their output ends facing the screen conveying device 5. In use, the first Z-axis drive mechanism 111 first drives the first truss 112 downwards, causing the screen suction nozzles 113 to suction the screen. Then, the first Z-axis drive mechanism 111 drives the first truss 112 upwards. Finally, the first X-axis drive mechanism 12 drives the screen gripping arm 11 to move along the X-axis, placing the screen into an open bag.

[0029] It should be noted that the first X-axis drive mechanism 12 and the first Z-axis drive mechanism 111 are both existing technologies, and their specific principles are the same as those of existing technologies, so they will not be elaborated here.

[0030] Combination Figure 7 and Figure 9 As shown, the bag feeding device 2 includes a base 20 and a material box 21 disposed on top of the base 20. The base 20 has a first push plate 201 and two push plates 202 distributed circumferentially, forming a U-shape. The material box 21 is disposed between the first push plate 201 and the two second push plates 202. The first push plate 201 pushes the material box 21 to move along the X-axis, and the two second push plates 202 are oppositely arranged to push the material box 21 to move along the Y-axis. In use, the material box 21 is placed between the first push plate 201 and the two second push plates 202. First, the first push plate 201 pushes the material box 21 to move along the X-axis, and then the second push plates 202 push the material box 21 to move along the Y-axis, so that the material box 21 is directly below the bag feeding device 3, facilitating the bag feeding device 3 to remove the material box.

[0031] Among them, the two second push plates 202 can clamp the material box 21 in opposite directions after moving the material box 21 into place, so as to prevent the material bag feeding device 3 from interfering with the material box 21 when picking up the material bag, which would cause the material box 21 to shift.

[0032] Furthermore, the bag feeding device 3 includes a bag feeding mounting frame 30, a bag feeding arm 31, and a second X-axis drive mechanism 32. The second X-axis drive mechanism 32 is fixedly mounted on the top of the bag feeding mounting frame 30, and the bag feeding arm 31 is slidably mounted on the top of the top of the bag feeding mounting frame 30 and is connected to the second X-axis drive mechanism 32. The second X-axis drive mechanism 32 is used to drive the bag feeding arm 31 to move along the X-axis.

[0033] The bag feeding arm 31 includes a second crossbeam 310, a second Z-axis drive mechanism 311, a second truss 312, and feeding nozzles 313. The second crossbeam 310 is slidably disposed on the top of the bag feeding mounting frame 30. The second Z-axis drive mechanism 311 is fixedly connected to the second crossbeam 310. The second truss 312 is disposed at the bottom of the second Z-axis drive mechanism 311 and is drively connected to the second Z-axis drive mechanism 311 to drive the second truss 312 to move along the Z-axis. Multiple feeding nozzles 313 are fixedly disposed at the bottom of the second truss 312 for adsorbing the bag.

[0034] Since the feeding nozzle 313 can only adsorb the top of the bag, when the feeding nozzle 313 adsorbs the bag and the second truss 312 is driven upward by the second Z-axis drive mechanism 311, the opening of the bag will naturally open under the combined action of its own gravity and the top adsorption force. In conventional technology, because the bottom of the bag is not constrained, the bottom of the bag will hang down under the pull of gravity, causing the opening to gradually expand, which is easy to cause interference with surrounding equipment during subsequent movement.

[0035] To avoid the above problems, the second truss 312 is provided with a clamping member 314 at the opening end of the bag. The two clamping members 314 are arranged facing each other on the second truss 312 to clamp the opening of the bag during the process of the feeding nozzle 313 adsorbing the bag and moving upward with the second truss 312, so as to restrict the opening degree of the bag opening and avoid interference with other devices during the movement due to the bag opening being too large.

[0036] The clamping component 314 includes a connecting block 3141 and a gripper cylinder 3142. The gripper cylinder 3142 is connected to the second truss 312 through the connecting block 3141. The gripper cylinder 3142 has two vertically arranged clamping arms 3143 facing the material bag feeding device 2. The two clamping arms 3143 are normally open to each other. When the feeding nozzle 313 absorbs the material bag, the two clamping arms 3143 close to each other to clamp the opening of the material bag.

[0037] It should be noted that the second X-axis drive mechanism 32 and the second Z-axis drive mechanism 311 are both existing technologies, and their specific principles are the same as those of existing technologies, so they will not be elaborated here.

[0038] Combination Figures 4 to 6As shown, the bag opening device 4 includes a bag opening mounting frame 40, a third Z-axis drive mechanism 41, and a bag top adsorption component 42. The third Z-axis drive mechanism 41 is fixedly mounted on the top of the bag opening mounting frame 40, and the bag top adsorption component 42 is mounted on the third Z-axis drive mechanism 41 and is connected to the third Z-axis drive mechanism 41 in a transmission manner. The third Z-axis drive mechanism 41 is used to drive the bag top adsorption component 42 to move along the Z-axis.

[0039] The bag top suction component 42 includes a slide plate 420 and a bag top suction nozzle 421. The slide plate 420 is connected to the third Z-axis drive mechanism 41. Multiple bag top suction nozzles 421 are fixedly installed at the bottom of the slide plate 420.

[0040] In use, when the bag feeding device 3 places the bag at the screen conveying device 5 below the bag opening device 4, the third Z-axis drive mechanism 41 drives the slide plate 420 to move down, so that the multiple bag top suction nozzles 421 at the bottom of the slide plate 420 adsorb the top of the bag. Then, the slide plate 420 is driven up by the third Z-axis drive mechanism 41 so that the top of the bag forms an opening relative to the bottom.

[0041] To further improve the bag opening effect, the bag opening device 4 also includes a bottom suction component 43. The bottom suction component 43 is fixedly installed on one side of the screen conveyor 5 below the bag opening device 4. The bottom suction component 43 includes a mounting block 430 and bottom suction nozzles 431. The mounting block 430 is fixedly installed on one side of the screen conveyor 5 below the bag opening device 4, and multiple bottom suction nozzles 431 are fixedly installed on the top of the mounting block 430. With this design, when the bag needs to be opened, the bottom suction component 43 can firmly adhere to the bottom of the bag, providing a stable downward pull. This creates a counterforce with the top suction component 42 above, making it easier to open the bag. Simultaneously, by including the bottom suction component 43, the device avoids the situation where the top suction component 42, when only configured with the bag opening device 4, sucks the entire bag upwards and causes it to detach from the screen conveyor 5 during opening.

[0042] The top adsorption member 42 and the bottom adsorption member 43 of the bag are located on one side of the bag opening, and the side of the bag opening faces the screen conveying device 1.

[0043] It should be noted that the third Z-axis drive mechanism 41 is existing technology, and its specific principle is the same as that of existing technology, so it will not be elaborated here.

[0044] Combination Figure 1As shown, the screen conveying device 5 is a belt conveyor. The conveyor belt has several raised strips 50 wound around its surface. These raised strips 50 extend in the same direction as the belt's movement, and are arranged longitudinally along the width of the belt. By using the raised strips 50, a gap is created between the screen and the belt conveyor, preventing direct contact between the screen and the belt. This significantly reduces the contact area between the screen and the belt, with support and transmission achieved solely through the raised strips 50, thus lowering the probability of screen damage caused by direct belt friction.
