Description

Technical Field

[0001] The utility model relates to the technical field of detection, in particular to an electromagnetic auxiliary heating device and flat paper box detection equipment. Background Art

[0002] To create a premium feel when removing the box and lid, existing gift boxes often incorporate magnetic sheets during the gluing process. A gift box with a magnetic sheet, also known as a magnetic folding gift box or a magnetic closure gift box, typically features a neodymium magnet, typically about 1-2mm thick, concealed at the bottom of the box's opening. The lid, typically a galvanized iron sheet, is used to hold the box closed when the magnet and iron sheet engage. When the box is brought close together, the magnets attract each other, closing and keeping the box closed.

[0003] Since multiple magnetic tiles are hidden under the wrapping paper on the gray board of the outer box, it is difficult to see whether they contain magnetic pieces by naked eye. Therefore, a device is needed to assist people in detecting whether there are magnetic pieces and iron pieces on the box cover. Utility Model Content

[0004] To overcome at least one of the aforementioned drawbacks of the prior art, the present invention provides an electromagnetically assisted heating device and flat-sheet paper box inspection equipment. This device utilizes electromagnetic heating of a magnetic sheet to assist manual inspection. When the magnetic sheet heats up due to the electromagnetic influence, manual inspection can detect the heat of the magnetic sheet. However, paper boxes without magnetic sheets remain unheated, allowing manual inspection to determine whether magnetic sheets and iron sheets are installed, significantly improving manual inspection accuracy.

[0005] The technical solution adopted by the present invention to solve the problem is:

[0006] An electromagnetic-assisted heating device comprises: a conveying device having a starting end and an ending end for conveying; an electromagnetic heating device, arranged in or below the conveying device and used to heat a box cover with a magnetic sheet on the conveying device; and an induction device, arranged on the side of the electromagnetic heating device close to the starting end of the conveying device and used to detect whether a box cover is approaching, so as to start the electromagnetic heating device.

[0007] By adopting the above solution, it is convenient for manual inspection of the box cover to detect whether the magnetic sheet inside the box cover is installed, thereby preventing missed inspection or false inspection caused by manual errors in naked eye observation.

[0008] Furthermore, the conveying device includes: a conveyor belt; a main drive motor, wherein the main drive motor is used to drive the conveyor belt to rotate; and a support frame, wherein the support frame is used to support the main drive motor and the conveyor belt.

[0009] By adopting the above solution, the magnetic sheet of the box cover can be heated on the assembly line, thereby improving the efficiency of manual inspection. At the same time, there is no need for manual labor to take the box cover back and forth for inspection, thereby improving the inspection speed.

[0010] Furthermore, the sensing device includes a sliding frame and a proximity sensor, the proximity sensor is detachably connected to the sliding frame, the sliding frame is slidably mounted on the support frame, and the sliding direction is consistent with the conveying direction of the conveyor belt.

[0011] By adopting the above solution, the electromagnetic heating device can be turned off or the power of the electromagnetic heating device can be lowered when there is no box cover on the conveyor belt, so as to achieve energy saving effect.

[0012] Furthermore, a foot frame is provided at the bottom of the conveying device, and the foot frame is used to support the support frame so as to keep the conveyor belt horizontal.

[0013] By adopting the above solution, the conveying device can be placed at a certain height by setting a tripod, which is helpful for people of different heights to perform inspections.

[0014] Furthermore, it also includes a displacement monitoring device, which is arranged on one side of the electromagnetic heating device close to the terminal end of the conveying device and is used to detect the distance between the box cover and the electromagnetic heating device.

[0015] By adopting the above solution, it is possible to determine whether the box cover is close to or far away from the electromagnetic heating device, thereby increasing or decreasing the power of the electromagnetic heating device.

[0016] Furthermore, the temperature of the magnetic sheet heated by the electromagnetic heating device is 45°C-55°C.

[0017] By adopting the above solution, the temperature of the magnetic sheet can be prevented from being too high, which may cause burns during manual inspection, while at the same time, manual inspection can be performed to ensure that the magnetic sheet exists.

[0018] Furthermore, the displacement monitoring device is a displacement encoder.

[0019] By adopting the above solution, position signals or data can be compiled and converted into signal forms that can be used for communication, transmission and storage, thereby improving intelligent control.

[0020] A flat paper box detection device comprises a detection device and an electromagnetic auxiliary heating device, wherein the detection device is used to detect the position of a magnetic sheet heated by the electromagnetic heating device in a box cover.

[0021] By adopting the above solution, the detection equipment can be used to assist manual detection to detect whether the position of the magnetic piece in the box cover is correct, thereby preventing the magnetic piece from being misplaced and causing failure of magnetic attraction with the clutch.

[0022] Furthermore, the detection device is an infrared camera.

[0023] By adopting the above solution, the heated magnetic sheets can be accurately identified.

[0024] To sum up, the electromagnetic auxiliary heating device and flat paper box detection equipment provided by the utility model have the following technical effects: by arranging an electromagnetic heating device on the conveying device, electromagnetic heating of the box cover conveyed on the conveying device can be achieved, which helps to heat the magnetic sheet inside the box cover. At the same time, the paper box is not affected by the electromagnetic heating device, which is conducive to manual identification of whether the box cover is installed with a magnetic sheet, thereby improving manual detection efficiency and detection accuracy.

[0028] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described and discussed below in conjunction with the drawings of the present invention. Obviously, what is described here is only a part of the examples of the present invention, not all the examples. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0029] In order to facilitate the understanding of the embodiments of the present invention, the following will be further explained with reference to specific embodiments as examples in conjunction with the drawings, and each embodiment does not constitute a limitation on the embodiments of the present invention.

[0030] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the present invention.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0032] Example 1 of the present utility model is shown in FIG. Figure 1-Figure 2 As shown, an electromagnetic assisted heating device is disclosed, including a conveying device 1, an electromagnetic heating device 2, an induction device 3 and a displacement monitoring device 4. The conveying device 1 has a starting end and an end end for conveying. Specifically, the conveying device 1 includes a conveyor belt 11, a main drive motor 12 and a support frame 13. The main drive motor 12 is used to drive the conveyor belt 11 to rotate, and the support frame 13 is used to support the main drive motor 12 and the conveyor belt 11. It can achieve the effect of heating the magnetic sheet of the box cover on the assembly line, improve the efficiency of manual inspection, and at the same time, there is no need for manual labor to take the box cover back and forth for inspection, thereby improving the inspection speed. The electromagnetic heating device 2 is arranged in the conveying device 1 or below the conveying device 1, and is used to heat the box cover with the magnetic sheet on the conveying device 1. In this embodiment 1, the electromagnetic heating device 2 is arranged below the conveying device 1. The sensing device 3 is disposed on the side of the electromagnetic heating device 2 near the starting end of the conveyor 1 and is used to detect whether a box cover is approaching, so as to activate the electromagnetic heating device 2. This facilitates manual inspection of the box cover to detect whether the magnetic sheet inside the box cover is installed, thereby preventing omissions or false detections caused by manual errors in visual observation. The displacement monitoring device 4 is disposed on the side of the electromagnetic heating device 2 near the end end of the conveyor 1 and is used to detect the distance between the box cover and the electromagnetic heating device 2. It can determine whether the box cover is approaching or moving away from the electromagnetic heating device 2, thereby increasing or decreasing the power of the electromagnetic heating device 2.

[0033] It should be noted that, in other embodiments, the conveying device 1 may also be a conveying device such as a conveying roller, which is not specifically limited in this embodiment. It only needs to be able to convey the box cover with the magnetic sheet 11, and the displacement monitoring device 4 may also be omitted.

[0034] In this first embodiment, the sensing device 3 includes a sliding frame and a proximity sensor. The proximity sensor is detachably connected to the sliding frame. The sliding frame is slidably mounted on the support frame 13, and its sliding direction is consistent with the conveying direction of the conveyor belt 11. When there is no box cover on the conveyor belt 11, the electromagnetic heating device 2 can be shut down or the power of the electromagnetic heating device 2 can be reduced to achieve energy saving. In other embodiments, only the proximity sensor can be provided to detect the proximity of the box cover to the electromagnetic heating device 2.

[0035] In order to prevent manual inspection of the conveyor belt 11 from requiring bending over, a tripod 14 is provided at the bottom of the conveyor device 1 in this embodiment 1. The tripod 14 is used to support the support frame 13 to keep the conveyor belt 11 level. The tripod 14 allows the conveyor device 1 to be at a certain height, facilitating inspection by personnel of different heights. In some embodiments, the tripod 14 can also be liftable, facilitating manual height adjustment and improving inspection comfort.

[0036] It should be noted that the temperature of the magnetic sheet heated by the electromagnetic heating device 2 is 45°C-55°C. The lowest temperature in this temperature range is a relatively sensitive starting value at which heat can be felt during manual detection. The highest temperature in this temperature range is the highest safe temperature for manual detection, which can prevent the temperature of the magnetic sheet from being too high, causing burns during manual detection, and satisfying the requirement that humans can identify the presence of the magnetic sheet.

[0037] In this embodiment 1, the displacement monitoring device 4 is a displacement encoder, which can compile and convert position signals or data into signal forms that can be used for communication, transmission and storage, thereby improving intelligent control.

[0038] The present invention also relates to a sheet-like paper box inspection device, comprising a detection device 5 and an electromagnetic auxiliary heating device. The detection device 5 is used to detect the position of a magnetic sheet in the box cover after being heated by the electromagnetic heating device 2. The detection device 5 can assist manual inspection to determine whether the magnetic sheet is correctly positioned in the box cover, thereby preventing the magnetic sheet from being misaligned and unable to engage the clutch magnetically. In this embodiment 1, the detection device 5 is an infrared camera that can accurately identify the heated magnetic sheet.

[0039] To sum up, the electromagnetic auxiliary heating device and flat paper box detection equipment provided by the utility model have the following technical effects: by arranging the electromagnetic heating device 2 on the conveying device 1, the box cover conveyed on the conveying device 1 can be electromagnetically heated, which helps to heat the magnetic sheet inside the box cover. At the same time, the paper box is not affected by the electromagnetic heating device 2, which is conducive to manual identification of whether the box cover is installed with a magnetic sheet, thereby improving manual detection efficiency and detection accuracy.

[0040] The technical means disclosed in the present invention are not limited to those disclosed in the above-mentioned embodiments, but also include technical solutions composed of any combination of the above-mentioned technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications are also considered to be within the scope of protection of the present invention.
