Description

A mask sheet dispensing auxiliary mechanism Technical Field

[0001] This utility model relates to an auxiliary mechanism for dispensing facial mask sheet. Background Technology

[0002] During the production of face masks, the stacked mask sheets need to be separated. Current methods involve fixing a thin stainless steel sheet to a cylinder-lifting base. When the stacked masks move below the cylinder-lifting base, the base descends as a whole, pushed by the cylinder. The stainless steel sheet on the base presses onto the mask sheet, causing it to bend due to its elasticity. As the mask sheets are removed one by one, the bending of the stainless steel sheet decreases, reducing the stack height. A photoelectric sensor detecting the mask sheet height triggers when the height reaches a certain point, causing the stacking mechanism to slowly rise until the sensor is no longer triggered. This process repeats until all the mask sheets are removed. During the removal process, the mask... The relative height of the stacked mask fabric is directly detected by a photoelectric sensor. After stacking to a certain height, the mask fabric may become uneven, and the edges may curl up during the retrieval process. If the protruding part or curled edge of the mask fabric happens to be at the detection position of the photoelectric sensor, it will cause a deviation between the mask fabric height and the set height. Since the retrieval height of the end effector is fixed, this will result in the inability to properly grasp the mask fabric or only grasping a portion of the mask fabric, leading to subsequent equipment malfunctions. Furthermore, the stainless steel spring has a small bending range, and the photoelectric sensor requires precise adjustment, making the equipment prone to damage during adjustments or mask fabric replacements. The greater the bending of the stainless steel spring, the greater the elasticity, causing inconsistent force on the mask fabric during retrieval by the end effector, resulting in abnormal retrieval.

[0003] In summary, due to the uneven stacking of the membrane fabric and the tendency for the membrane fabric to warp, the photoelectric sensor is prone to false detections of the actual height of the stacked membrane fabric during the detection process. This affects the normal membrane picking of the end effector, resulting in the inability to pick up the membrane fabric or only picking up a portion of the membrane fabric. The inability to pick up the membrane fabric affects the production efficiency of the equipment, while only picking up a portion of the membrane fabric affects the failure rate and defect rate of the equipment. Summary of the Invention

[0004] The purpose of this invention is to overcome the defects of the prior art and provide an auxiliary mechanism for picking up face mask sheets. This mechanism can ensure that the sheet is flat during the picking process of stacked face mask sheets and that the height of the stacked face mask sheets remains consistent when the end effector picks up the face mask sheets, thereby improving the success rate of the end effector picking up the face mask sheets.

[0005] The technical solution to achieve the above objective is: a mask sheet dispensing auxiliary mechanism, comprising a mask lifting mechanism and at least one mounting pressure ring, wherein:

[0006] The mask lifting mechanism includes a lifting mounting base and a lifting cylinder disposed thereon;

[0007] The mounting ring is positioned above the lifting mounting base. Each mounting ring is equipped with a detection calibration block. A photoelectric sensor is mounted above the detection calibration block via a bracket. Several brush assemblies are evenly distributed on the upper surface of each mounting ring. An upper magnet is positioned near each brush assembly.

[0008] A lower magnet is located directly below each upper magnet, and each lower magnet is mounted on the lifting mounting base via a linear bearing;

[0009] The mounting ring and the lifting mounting base are connected together by the magnetic attraction between the upper magnet and the lower magnet;

[0010] The photoelectric sensor communicates with the lifting cylinder.

[0011] In the above-mentioned mask sheet dispensing auxiliary mechanism, the number of mounting pressure rings is two, and the two mounting pressure rings are arranged side by side above the lifting mounting base.

[0012] In the above-mentioned mask sheet dispensing auxiliary mechanism, the linear bearing is fixed to the lifting mounting base by screws, the lower magnet is connected to the guide shaft by screws, the guide shaft passes through the linear bearing, and a lower limit ring is installed at the bottom of the guide shaft.

[0013] The above-mentioned mask sheet dispensing auxiliary mechanism includes a brush assembly comprising a brush and a brush handle connected thereto. The brush handle has a strip-shaped hole and is fixed to the mounting ring by a bolt located in the strip-shaped hole. The extension length of the brush is adjusted by the mounting position of the bolt in the strip-shaped hole.

[0014] In the above-mentioned mask sheet dispensing auxiliary mechanism, the output end of the lifting cylinder is arranged downwards, and the output end of the lifting cylinder is connected to a mask sheet support frame.

[0015] In the above-mentioned mask sheet dispensing auxiliary mechanism, a lifting guide shaft is provided between the lifting mounting base and the mask sheet support frame.

[0016] The mask sheet picking auxiliary mechanism of this utility model can ensure the flatness of the stacked mask sheets during the picking process and ensure that the height of the stacked mask sheets remains consistent when the picking end actuator grasps the mask sheet, thereby improving the success rate of the picking end actuator in grasping the mask sheet. The specific beneficial effects are reflected in:

[0017] (1) By using photoelectric sensors to detect the calibration block on the mounting ring, it is possible to avoid deviations in the detection height of the mask stacking caused by uneven stacking of the mask fabric or the mask fabric being lifted, which could further cause the end effector of the mask gripping device to fail to grip during the gripping process.

[0018] (2) In the original mechanism, the stainless steel sheet of the pressure film gradually bends during the lifting process of the mask lifting mechanism. The greater the bend, the greater the pressure on the mask. This situation causes the force of the end effector to grasp the mask during the film retrieval process to be different, resulting in abnormal grasping. In this utility model, a linear bearing is installed in conjunction with a magnet and other components. During the lifting process of the mask lifting mechanism, the pressure ring will rise synchronously with the mask lifting mechanism. The bend of the brush assembly remains consistent, and the pressure on the mask will also be consistent. The force of the end effector to grasp the mask during the film retrieval process is consistent, and the grasping is also consistent.

[0019] (3) The linear bearing and magnetic structure of the film taking auxiliary mechanism of this utility model can ensure that the mounting pressure ring and its components have a certain lifting range and easy detachment characteristics, ensuring the fault tolerance rate of the structure under abnormal conditions, thereby improving the stability of the equipment.

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, its specific embodiments are described in detail below with reference to the accompanying drawings:

[0026] Please refer to Figures 1, 2, 3, 4, and 5 for the preferred embodiment of this utility model: a mask sheet dispensing auxiliary mechanism, comprising a mask lifting mechanism 10 and at least one mounting pressure ring 8. The number of mounting pressure rings 8 can be set as needed; in this embodiment, there are two mounting pressure rings 8.

[0027] The mask lifting mechanism 10 includes a lifting mounting base 2 and a lifting cylinder 7 mounted thereon. The output end of the lifting cylinder 7 is downward-facing and connected to a mask fabric support frame 11. A lifting guide shaft 12 is provided between the lifting mounting base 2 and the mask fabric support frame 11, and the mask fabric support frame 11 moves along the lifting guide shaft 12 during the lifting process.

[0028] Two mounting rings 8 are arranged side-by-side above the lifting mounting base 2, which has a mask outlet that matches the mounting rings 8. Each mounting ring 8 is equipped with a detection calibration block 81, and a photoelectric sensor 1 is mounted above the detection calibration block 81 via a bracket. The photoelectric sensor 1 communicates with the lifting cylinder 7. The photoelectric sensor 1 is used to detect the position of the detection calibration block 81 and feeds back a signal to the lifting cylinder 7.

[0029] Each mounting ring 8 has several brush assemblies 6 evenly distributed on its upper surface. In this embodiment, the number of brush assemblies 6 is four. Each brush assembly 6 includes a brush 61 and a brush handle 62 connected thereto. The brush handle 62 has a strip hole 63. The brush handle 62 is fixed to the mounting ring 8 by bolts provided in the strip hole 63. The extension length of the brush 61 can be adjusted by the installation position of the bolts in the strip hole 63.

[0030] Each brush assembly 6 has an upper magnet 5 nearby, and there are four upper magnets 5 in total.

[0031] A lower magnet 4 is provided directly below each upper magnet 5, and each lower magnet 4 is mounted on the lifting mounting base 2 via a linear bearing 3. Specifically, the linear bearing 3 is fixed to the lifting mounting base 2 by screws, and the lower magnet 4 is connected to the guide shaft by screws. The guide shaft passes through the linear bearing 3, and a lower limit ring is installed at the bottom of the guide shaft. The lower limit ring is used to limit the lower part of the guide shaft.

[0032] The upper magnet 5 has its N pole facing down, and the lower magnet 4 has its S pole facing up. The four lower magnets 4 and the four upper magnets 5 attract each other due to their opposite magnetic poles. The mounting ring 8 and the lifting mounting base 2 are connected together by the magnetic attraction between the upper magnets 5 and the lower magnets 4. This method allows the mounting ring 8 and the accessories (brush assembly 6 and upper magnet 5) mounted on the mounting ring 8 to have a certain vertical movement space, and the mounting ring 8 and the accessories mounted on the mounting ring 8 can be quickly installed or removed.

[0033] In this utility model, the mask sheet dispensing auxiliary mechanism involves the mask transfer mechanism 9 transferring the stacked masks 100 to the mask sheet support 11 of the mask lifting mechanism 10. Under the action of the lifting cylinder 7, the mask lifting mechanism 10 lifts the stacked masks and components. When the masks are lifted to the brush assembly 6, the brush assembly 6 presses down on the top of the masks, simultaneously moving the mounting ring 8 and its mounted accessories upwards until the detection calibration block 81 on the mounting ring 8 is detected by the photoelectric sensor 1. The photoelectric sensor 1 then sends a positioning signal to the lifting cylinder 7, causing the lifting cylinder 7 to stop working, and the mask sheet support 11 of the mask lifting mechanism 10 to stop rising. As the end effector removes the masks one by one, the height of the stacked masks gradually decreases, and the mounting ring 8 and the accessories mounted on the mounting ring 8 also gradually decrease. When the detection calibration block on the mounting ring 8 is not detected by the photoelectric sensor 1, the photoelectric sensor 1 sends a non-position signal to the lifting cylinder 7, the lifting cylinder 7 operates, and the mask fabric support frame 11 of the mask lifting mechanism 10 rises until the detection calibration block on the mounting ring 8 is detected by the photoelectric sensor 1. Then the photoelectric sensor 1 sends a position signal to the lifting cylinder 7 again, the lifting cylinder 7 stops working, the mask lifting mechanism stops rising, and the end effector removes the masks one by one. This cycle continues until all the masks are removed.

[0034] This utility model discloses a mask fabric removal auxiliary mechanism. The original pressing metal sheet is replaced with a brush (the pressing area of ​​the brush can be adjusted according to the hardness of the mask fabric). The mounting ring 8 is separated from the mask lifting mechanism 10. The photoelectric sensor calibration block is changed from the mask to the calibration block 81 on the mounting ring 8, thus avoiding deviations in detection height caused by the mask fabric lifting. It can be used in mask fabric folding machines and for separating and pressing stacked materials (fabric, paper, plastic bags, etc.), improving the height detection accuracy of the mechanism, ensuring material flatness, and further improving the overall stability of the equipment.

[0035] In summary, the mask sheet picking auxiliary mechanism of this utility model can ensure the flatness of the stacked mask sheets during the picking process and ensure that the height of the stacked mask sheets remains consistent when the picking end actuator picks up the mask sheets, thereby improving the success rate of the picking end actuator picking up the mask sheets.

Any changes or modifications to the above embodiments within the scope of the essential spirit of the present utility model will fall within the scope of the claims of the present utility model.
