Description

Technical Field

[0001] The present application relates to the field of packaging technology, and in particular to a packaging board and a cutting quality detection method for the packaging board. Background Art

[0002] Foaming material is a very practical packaging material for compressor packaging, transportation and storage. After the compressor is bundled, the foam can ensure that the compressor will not shift, collapse or produce violent vibrations that may cause damage to the compressor components under various transportation conditions. It can also ensure that the material will not deform when stacked under static load for a long time, causing uneven force and damaging the compressor's appearance.

[0003] The foaming of the packaging compressor usually appears in the form of a plate. In actual packaging operations, the plate needs to be cut into two upper and lower fixed plates, and the compressor needs to be fixed between the upper and lower fixed plates. However, due to the different models of compressors, the structural forms of their bases are diverse, resulting in the lower fixed plate requiring a variety of sizes and specifications. This involves checking and calibrating the cutting dimensions of the packaging plates corresponding to different compressor models. In the process of cutting the plates, cutting through, cutting thin, and cutting obliquely often occur. In addition, measuring tools need to be used to detect the above-mentioned quality problems in the cutting of the packaging plates, which is time-consuming and prone to false detection and missed detection.

[0016] Optionally, a vertical distance between the cutting surface and the first surface is smaller than a distance between the cutting surface and the second surface, and the vertical distance between the cutting surface and the first surface is 35 to 85 mm.

[0017] Optionally, the packaging board is made of foam material.

[0018] On the other hand, an embodiment of the present application further provides a cutting quality detection method, which is applied to the packaging board, and the cutting quality detection method includes:

[0019] Calibrate the cutting size of the cutting device according to the cutting surface in the step portion;

[0020] The packaging board is cut by the cutting device, and the upper fixing plate and the lower fixing plate formed by cutting the packaging board are visually inspected. If the cutting surface exists or partially exists, the cutting size of the cutting device is recalibrated; if the cutting surface does not exist, the packaging boards are cut in batches.

[0025] The operator performs visual inspection on the upper and lower fixed plates formed by the trial calibration cutting. If the cutting surface exists or partially exists, the cutting size accuracy calibration is carried out. Otherwise, batch cutting is started.

[0026] During the batch cutting process, the operator only needs to cut along the cutting surface to better ensure the cutting flatness, and it is not easy to cut through, cut thinly, cut obliquely, etc. during the cutting process, which reduces the subsequent trimming process, reduces the production cost, and ensures that the thickness of the lower fixed plate and / or the upper fixed plate is not cut too thin or cut unevenly and locally too thin, avoiding damage caused by a decrease in the strength of the lower fixed plate and / or the upper fixed plate.

[0027] During the packaging board cutting size calibration and cutting quality inspection process, quality inspectors do not need to use measuring tools to check the flatness of the packaging board cutting. They can check whether the upper and lower fixed plates are qualified based on the feedback from the visual inspection device on whether the set cutting surface disappears, greatly reducing the complexity and time of inspection.

[0038] It should be noted that, in the absence of conflict, the features in the embodiments of this application can be combined with each other.

[0039] As disclosed in the background technology section, the foaming of the packaging compressor usually appears in the form of a plate. In actual packaging operations, the plate needs to be cut into two upper and lower fixed plates, and the compressor needs to be fixed between the upper and lower fixed plates. However, due to the different models of compressors, there are many structural forms of the compressor base, resulting in the lower fixed plate requiring a variety of sizes and specifications. This involves checking and calibrating the cutting dimensions of the plate corresponding to different compressor models. In the process of cutting the plate, cutting through, cutting thin, and cutting obliquely often occur. In addition, when detecting the above-mentioned quality problems of the packaging plate cutting, measuring tools need to be used for measurement, which is time-consuming and prone to misdetection and missed detection. The embodiments of the present application provide a packaging plate that is at least used to solve the above-mentioned technical problems.

[0040] Please refer to Figure 1-Figure 3 The packaging board 100 provided in an embodiment of the present application has a first surface 110 and a second surface 120 arranged in parallel along its own thickness direction. At least one side surface of the packaging board 100 is provided with a step portion 132. The end surface of the step portion 132 parallel to the first surface 110 or the second surface 120 is a cutting surface, and the packaging board 100 is used for cutting along the cutting surface.

[0041] It should be noted that the packaging plate 100 is divided into an upper fixed plate 140 and a lower fixed plate 150 after being cut along the cutting surface. The upper fixed plate 140 is provided with a top accommodating cavity, and the lower fixed plate 150 is provided with a bottom accommodating cavity. When the packaging plate 100 is used to package the compressor, the top of the compressor 200 is assembled in the top accommodating cavity and the bottom of the compressor 200 is assembled in the bottom accommodating cavity during the packaging process, thereby fixing the compressor 200 between the upper and lower fixed plates.

[0042] Since the first surface 110 and the second surface 120 are parallel, and the cutting surface is parallel to the first surface 110 or the second surface 120 , the thickness of the upper fixing plate 140 and the lower fixing plate 150 obtained after cutting can be kept consistent.

[0043] During the actual cutting process, a step portion 132 is provided on at least one side surface of the packaging board 100, and the end surface of the step portion 132 that is parallel to the first surface 110 or the second surface 120 of the packaging board 100 is the cutting surface. Therefore, during the actual cutting process, the operator only needs to calibrate the cutting size of the cutting equipment according to the cutting surface provided on at least one side surface of the packaging board 100, without having to check the cutting size of the packaging board 100 according to the product model.

[0044] During the production process of the packaging board 100 , the step portion 132 can be pre-formed by mold forming, laser engraving, or machining. The specific method of forming the step portion 132 can be flexibly selected according to the board material and the production process.

[0045] The packaging board 100 can be rectangular or cylindrical. When the packaging board 100 is rectangular, the step portion 132 can be set on two opposite sides of the packaging board 100; when the packaging board 100 is cylindrical, the step portion 132 can be set at any position on the side of the packaging board 100.

[0046] In some embodiments, at least one side of the packaging board 100 is provided with a groove 130, the groove 130 has an inner bottom surface 131 and at least one step portion 132, the end surface of the step portion 132 parallel to the first surface 110 or the second surface 120 of the packaging board 100 is a cutting surface, and the step portion 132 has at least one cutting surface.

[0047] When the packaging board 100 is in the shape of a rectangular parallelepiped, the packaging board 100 has a groove 130 on one side surface, or has grooves 130 on two opposite sides, or has grooves 130 on three sides, or has grooves 130 on all four sides. When the packaging board 100 is in the shape of a cylinder, the packaging board 100 has at least one groove 130 at any position on its side surface.

[0048] The groove 130 can be formed on the side of the packaging board 100 by mold molding. On the side where the groove 130 is provided, the inner bottom surface 131 of the groove 130 is parallel to the side, and all inner side surfaces of the groove 130 are perpendicular to the inner bottom surface 131 of the groove 130. The inner side surface of the step portion 132 of the groove 130 that is parallel to the first surface 110 or the second surface 120 is a cutting surface.

[0049] In other embodiments, the angle between the inner side surface of the groove 130 except the cutting surface and the inner bottom surface 131 of the groove 130 may be greater than or less than 90 degrees, that is, the inner side surface of the groove 130 except the cutting surface may be inclined relative to the inner bottom surface 131 of the groove 130.

[0050] In some embodiments, the groove 130 has a first inner side surface 1321 and a second inner side surface 1322 connected to the first inner side surface 1321, the second inner side surface 1322 is set at an angle to the first inner side surface 1321, the second inner side surface 1322 is a cutting surface, and the second inner side surface 1322 is parallel to the first surface 110 or the second surface 120; the groove 130 also has a third inner side surface 1323, the third inner side surface 1323 and the first inner side surface 1321 are not on the same straight line, the third inner side surface 1323 is connected to the second inner side surface 1322, and the third inner side surface 1323 and the second inner side surface 1322 are set at an angle; the first inner side surface 1321, the second inner side surface 1322 and the third inner side surface 1323 constitute the step portion 132.

[0051] In an optional embodiment, the groove 130 has two oppositely disposed stepped portions 132, and in the thickness direction of the packaging board 100, the two second inner side surfaces 1322 are parallel to the first surface 110 or the second surface 120 and are at equal vertical distances therefrom. That is, the two second inner side surfaces 1322 are parallel to the first surface 110 or the second surface 120, the vertical distance from one second inner side surface 1322 to the first surface 110 is equal to the vertical distance from the other second inner side surface 1322 to the first surface 110, and the vertical distance from one second inner side surface 1322 to the second surface 120 is equal to the vertical distance from the other second inner side surface 1322 to the second surface 120.

[0052] In this embodiment, the angle between the second inner side surface 1322 and the first inner side surface 1321 is 90°. In other embodiments, the angle between the second inner side surface 1322 and the first inner side surface 1321 may be greater than or less than 90°.

[0053] Furthermore, the first inner side surface 1321 is connected between the first surface 110 and the corresponding second inner side surface 1322, and the inner bottom surface 131 forms a first identification area 1311 between the first surface 110, the first inner side surface 1321 and the second inner side surface 1322, and a first identification is provided in the first identification area 1311.

[0054] The first identification area 1311 is formed between the plane where the first surface 110 is located, the plane where the two second inner side surfaces 1322 are located, and the planes where the two first inner side surfaces 1321 are located respectively. The first identification can be convex, concave, printed, labeled, etc. on the inner bottom surface 131 of the groove 130. The first identification can be selected as an identification corresponding to the lower fixed plate 150, such as the code of the lower fixed plate 150.

[0055] By providing a first identification in the first identification area 1311, when the first identification is the code for the lower fixed plate 150, the operator can quickly identify the lower fixed plate 150 among the two fixed plates after cutting, and can quickly use it for the bottom packaging of the compressor 200 of the corresponding compressor model.

[0056] In an optional embodiment, the groove 130 also has two third inner side surfaces 1323 arranged opposite to each other, and the two third inner side surfaces 1323 are respectively connected to the two second inner side surfaces 1322, and the third inner side surfaces 1323 and the second inner side surfaces 1322 are arranged at an angle; a second identification area 1312 is formed between the second surface 120, the second inner side surface 1322 and the third inner side surface 1323, and the inner bottom surface 131 is provided with a second identification in the second identification area 1312.

[0057] In this embodiment, the angle between the third inner side surface 1323 and the second inner side surface 1322 is 90°, and the distance between the two third inner side surfaces 1323 is smaller than the distance between the two first inner side surfaces 1321. In other embodiments, the angle between the third inner side surface 1323 and the second inner side surface 1322 may be greater than or less than 90°, and the distance between the two third inner side surfaces 1323 may be greater than or less than the distance between the two first inner side surfaces 1321.

[0058] The second identification area 1312 is formed between the plane where the second surface 120 is located, the plane where the two second inner side surfaces 1322 are located, and the planes where the two third inner side surfaces 1323 are located. The second identification can be convex, concave, printed, labeled, etc. on the inner bottom surface 131 of the groove 130. The second identification can be selected as an identification corresponding to the upper fixed plate 140, such as the code of the upper fixed plate 140.

[0059] By providing a second identification in the second identification area 1312, when the second identification is the code for the upper fixed plate 140, the operator can quickly identify the upper fixed plate 140 among the two fixed plates after cutting, and can quickly use it for the top packaging of the compressor 200 of the corresponding compressor model.

[0060] In an optional embodiment, the groove 130 may further have a fourth inner side surface 133 connected between the two third inner side surfaces 1323 , and the second identification area 1312 is formed between the fourth inner side surface 133 , the second inner side surface 1322 and the third inner side surface 1323 .

[0061] The fourth inner side surface 133 may be optionally perpendicular to the inner bottom surface 131 of the groove 130, and the angle between the fourth inner side surface 133 and the inner bottom surface 131 of the groove 130 may be greater than or less than 90°. The second identification area 1312 is formed between the plane where the fourth inner side surface 133 is located, the plane where the two second inner side surfaces 1322 are located, and the planes where the two third inner side surfaces 1323 are located.

[0062] In some other embodiments, at least one side surface of the packaging board 100 is provided with a protrusion, the protrusion having an end surface and at least one step portion 132, and the end surface of the step portion 132 parallel to the first surface or the second surface of the packaging board is a cutting surface.

[0063] When the packaging board 100 is in the shape of a rectangular parallelepiped, the packaging board 100 may have a protrusion on one side surface, or may have protrusions on two opposite sides, or may have protrusions on three sides, or may have protrusions on all four sides. When the packaging board 100 is in the shape of a cylinder, the packaging board 100 may have at least one protrusion at any position on its side surface.

[0064] On the side with the protrusion, the end face of the protrusion is parallel to the side face, all outer side faces of the protrusion are perpendicular to the end face of the protrusion, and the outer side face of the step portion 132 of the protrusion parallel to the first surface 110 or the second surface 120 is a cutting surface.

[0065] In other embodiments, the angle between the outer side surface of the protrusion excluding the cutting surface and the end surface of the protrusion may be greater than or less than 90 degrees, that is, the outer side surface of the protrusion excluding the cutting surface may be inclined relative to the end surface of the protrusion.

[0066] In this embodiment, the vertical distance between the cutting surface and the first surface 110 is smaller than the vertical distance between the cutting surface and the second surface 120 , and the vertical distance between the cutting surface and the first surface 110 is 35-85 mm.

[0067] It should be noted that, according to packaging requirements, the thickness of the lower fixed plate 150 obtained after cutting the packaging plate 100 can be smaller than the thickness of the upper fixed plate 140. The thickness of the lower fixed plate 150 is the distance between the cutting surface and the first surface 110, and the thickness of the upper fixed plate 140 is the distance between the cutting surface and the second surface 120.

[0068] Since the lower fixed plate 150 needs to carry the compressor 200, it is necessary to ensure that the thickness of the lower fixed plate 150 is not too thin or the lower fixed plate 150 is not cut unevenly or is too thin in some parts, that is, the distance between the cut surface and the first surface 110 should not be too small, and the horizontal flatness of the cut surface should be maintained. If the thickness of the lower fixed plate 150 is too thin or the cutting thickness is uneven, the strength of the lower fixed plate 150 will be reduced, and the lower fixed plate 150 will be easily crushed when carrying the compressor 200, and the lower fixed plate 150 will also be easily damaged when the robot arm grasps it.

[0069] Exemplarily, the distance between the cutting surface and the first surface 110 is 35mm, 45mm, 55mm, 65mm, 75mm or 85mm. It can be understood that the distance between the cutting surface and the first surface 110 depends on the product packaging requirements of different compressor models, as long as it can ensure that the lower fixed plate 150 has better bearing capacity after cutting.

[0070] Of course, it is understandable that the thickness of the upper fixing plate 140 should not be too thin or the upper fixing plate 140 should not be cut unevenly or partially too thin, otherwise the strength of the upper fixing plate 140 will decrease and it will be easy to be damaged.

[0071] In this embodiment, the packaging board 100 is made of a foam material, for example, EPS material, EPE material or EPP material.

[0072] It should be noted that EPS material is a lightweight closed-cell foam material made of polystyrene beads and foaming agent, EPE material is a material formed by physical foaming of low-density polyethylene resin, and EPP material is a high-density foam material.

[0073] Taking the foam material as EPS material as an example, a hot wire cutting method is usually used when cutting the packaging board 100. When using the hot wire cutting method, a heated metal wire is generally used to cut the EPS material, thereby forming a clean and smooth cut. This method can better ensure the flatness of the cut.

[0074] The embodiment of the present application further provides a method for detecting the cutting quality of a packaging board, which is applied to the packaging board 100 described above. The method for detecting the cutting quality of a packaging board includes:

[0075] Step 1: Calibrate the cutting size of the cutting equipment according to the cutting surface in the step portion 132 .

[0076] Step 2: Use cutting equipment to cut the packaging board 100, and perform visual inspection on the upper fixed plate 140 and the lower fixed plate 150 formed by cutting the packaging board 100. If the cutting surface exists or partially exists, the cutting size of the cutting equipment is recalibrated; if the cutting surface does not exist, the packaging board 100 is cut in batches.

[0077] Step 3: Perform visual inspection on the upper fixing plate 140 and the lower fixing plate 150 formed by batch cutting. If the cutting surface exists or partially exists, it is determined to be a defective product; if the cutting surface does not exist, it is determined to be a qualified product.

[0078] In the above steps, the cutting size calibration of the cutting equipment actually refers to the cutting height and level calibration of the cutting equipment. After calibration, the packaging board 100 is cut along the cutting surface to form the upper fixed board 140 and the lower fixed board 150. The upper fixed board 140 and the lower fixed board 150 are visually inspected using existing visual inspection equipment. If the cutting surface still exists or partially exists on at least one of the upper fixed board 140 and the lower fixed board 150, it indicates that the cutting height and level calibration are not in place, and a second calibration is performed. If the cutting surface does not exist, the packaging board 100 is cut in batches. The upper fixed board 140 and the lower fixed board 150 formed by batch cutting are visually inspected again using the visual inspection equipment. If the cutting surface still exists or partially exists on at least one of the upper fixed board 140 and the lower fixed board 150, the fixed board with the cutting surface is determined to be defective. If the cutting surface does not exist, the fixed board is determined to be qualified. After the fixed board is determined to be defective or qualified, it can be marked.

[0079] The technical effects of the packaging board 100 and the cutting quality detection method for packaging boards provided in the embodiments of the present application include at least:

[0080] By providing a step portion 132 on at least one side surface of the packaging board 100, the end surface of the step portion 132 parallel to the first surface 110 or the second surface 120 of the packaging board 100 serves as a cutting surface. Therefore, during the actual cutting process, the operator can calibrate the cutting size of the cutting equipment based on the cutting surface provided on at least one side surface of the packaging board 100, without having to check the cutting size of the packaging board 100 according to the product model.

[0081] The upper fixing plate 140 and the lower fixing plate 150 formed by trial production calibration cutting of the packaging plate 100 are visually inspected using a visual inspection device. If the cutting surface exists or partially exists, a secondary calibration of the cutting size is performed. Otherwise, batch cutting is started.

[0082] During the batch cutting process, the operator only needs to cut along the cutting surface to better ensure the cutting flatness, and it is not easy to cut through, cut thinly, cut obliquely, etc. during the cutting process, which reduces the subsequent trimming process, reduces the production cost, and ensures that the thickness of the lower fixed plate 150 and / or the upper fixed plate 140 is not cut too thin or cut unevenly and partially too thin, avoiding damage caused by the reduction of strength of the lower fixed plate 150 and / or the upper fixed plate 140.

[0083] During the process of calibrating and debugging the cutting size and inspecting the cutting quality of the packaging board 100, the quality inspectors do not need to use measuring tools when checking the cutting flatness of the packaging board 100. The visual inspection device can be used to feedback whether the set cutting surface disappears to realize the quality inspection of whether the upper fixed plate 140 and the lower fixed plate 150 are qualified, thereby greatly reducing the complexity and time of inspection.

[0084] To sum up, the packaging board 100 and the cutting quality inspection method for the packaging board provided in the present application have a first surface 110 and a second surface 120 arranged in parallel along the thickness direction of the packaging board 100. At least one side of the packaging board 100 is provided with a step portion 132. The end face of the step portion 132 parallel to the first surface 110 or the second surface 120 of the packaging board 100 is a cutting surface.
