Description

Technical Field

[0001] The present disclosure generally relates to the technical field of mechanical manufacturing, and in particular, to a detection device for preventing overlapping parts from being loaded, and more specifically, to a detection device for preventing overlapping thin plate-shaped parts from being loaded. Background Art

[0002] In industrial production, small thin plate parts are used in the production process of industrial products such as automobile taillight reinforcements or hinge back panel reinforcements. In some cases, such as due to the presence of grease, small thin plate parts are prone to overlap and stick together in two or more layers. When picking up such thin plate parts, their own weight is not enough to overcome the force of grease adhesion, resulting in two or more layers of thin plate parts being loaded in an overlapping manner. Since the weight of a single-layer part is very light and the layer thickness is very thin, overlapping parts are not easy to be found. Once two or more layers of overlapping parts are loaded, difficulties will be encountered during subsequent processing, or mechanical components will fail after assembly, causing the entire mechanical component to be scrapped or need to be repaired. Therefore, in production practice, a detection device is needed to prevent the loading of overlapping parts to help operators promptly detect and avoid loading overlapping parts. Utility Model Content

[0003] One of the objectives of the present disclosure is to provide a detection device that can at least be used to solve the above-mentioned technical problems (eg, prevent the loading of overlapping thin plate-shaped parts) and achieve other additional advantages.

[0011] In some embodiments, the main body further includes a sensor mounting hole located at a first side of the gap, and the sensor mounting hole is configured as a through hole leading to the gap of the detection area.

[0012] In some embodiments, the sensor mounting hole includes a first section and a second section, the first section has a smaller diameter and the second section has a larger diameter, thereby forming a step portion between the first section and the second section, wherein the sensor is mounted in the first section and the sensing element of the sensor faces the gap.

[0013] In some embodiments, the body further includes a second through hole located at a second side of the gap opposite to the first side, the second through hole leading to the gap and being substantially coaxial with the sensor mounting hole.

[0014] In some embodiments, a rounded transition portion between the inclined guide surface and a side wall of the gap in the detection area is higher than a highest point of a sensing range of the sensor.

[0015] In some embodiments, the detection device is equipped with a plurality of bodies, and the gaps between the plurality of bodies have different gap widths.

[0016] In some embodiments, the body includes two body halves, and a gap between the two body halves forms the gap of the detection area, wherein the two body halves are configured to be movable relative to each other so that the width of the gap between the two body halves changes with the movement of the body halves.

All terms (including technical terms and scientific terms) used in the specification have the meanings commonly understood by those skilled in the art unless otherwise defined. For the sake of simplicity and / or clarity, well-known functions or structures may not be described in detail.

[0026] The singular forms "a", "the" and "the" used in the specification include the plural forms unless clearly indicated. The terms "include", "comprise" and "contain" used in the specification indicate the presence of the claimed features, but do not exclude the presence of one or more other features.

In contrast, when an element is said to be "directly" "on", "directly attached", "directly connected", "directly coupled", or "directly contacting" another element, there will be no intermediate element. In the specification, a feature is arranged "adjacent" to another feature, which may refer to a feature having a portion that overlaps with an adjacent feature or a portion that is located above or below an adjacent feature.

[0028] In the specification, spatial relational terms such as "upper", "lower", "left", "right", "front", "back", "higher", "lower", etc. may describe the relationship of one feature to another feature in the drawings.

[0029] like Figure 1 As shown, the detection device for preventing overlapping parts from being loaded may include a base plate 1 and a main body 2. The main body 2 may be mounted on the base plate 1. The base plate 1 includes a base mounting portion 11 and a main body mounting portion 12, wherein the main body 2 may be fixed to the base plate 1 at the main body mounting portion 12 using a fastening element (e.g., a screw), and the base plate 1 may be fixed to a base (e.g., a work surface, a workshop wall), etc., using a fastening element (e.g., a screw) at the base mounting portion 11.

[0030] In some embodiments, the base mounting portion 11 may be configured as an elongated through hole. When a fastening element such as a screw is not completely tightened, the elongated through hole can slide relative to the fastening element such as a screw to adjust the position of the base plate 1 .

[0031] In some embodiments, the body 2 may include a base plate mounting portion 24 to fix the fastening element. The base plate mounting portion 24 may be configured as a hole with an internal thread, and the body mounting portion 12 of the base plate 1 may be configured as a through hole. A screw may be passed through the through hole of the body mounting portion 12, and the screw may be screwed into the internal thread hole of the base plate mounting portion 24 to implement fixation. In some embodiments, the through hole of the body mounting portion 12 has a stepped cross-sectional shape, so that after the screw is installed, the head of the screw is hidden in the through hole of the body mounting portion 12, and will not hinder the fit between the base plate 1 and the substrate.

[0032] In some embodiments, the detection device may also include only the main body 2 without including the base plate 1 .

[0033] The body 2 may include at least some of a detection area 21 , a guide portion 22 , a sensor installation hole 23 , and a sensor (not shown).

[0034] In some embodiments, the detection area 21 of the main body 2 may include a gap for inserting a thin plate-shaped part, and the width of the gap is configured to be greater than the thickness of a single thin plate-shaped part and less than twice the thickness of a single thin plate-shaped part, so that a single thin plate-shaped part can smoothly enter the gap while overlapping thin plate-shaped parts will be blocked outside the gap. In some embodiments, the width of the gap may be 1.1 times to 1.9 times the thickness of the thin plate-shaped part. In some embodiments, the width of the gap may be 1.2 times to 1.8 times the thickness of the thin plate-shaped part. In some embodiments, the width of the gap may be 1.3 times to 1.7 times the thickness of the thin plate-shaped part. In some embodiments, the width of the gap may be 1.4 times to 1.6 times the thickness of the thin plate-shaped part. In some embodiments, the width of the gap may be 1.5 times the thickness of the thin plate-shaped part. Preferably, the gap width of the main body 2 can adopt a smaller width range, such as 1.5 times or 1.4-1.6 times the thickness of the thin plate-shaped part, so that a single thin plate-shaped part can be easily inserted, and even after the gap is worn and widened to a certain extent, it will not be able to accommodate two thin plate-shaped parts.

[0035] In production, the thickness of common thin plate parts is 0.7 mm, 1.0 mm and 1.2 mm. Therefore, in some embodiments, the width of the gap can be set to 1.3 mm, which is suitable for detecting thin plate parts with thicknesses of 0.7 mm, 1.0 mm and 1.2 mm.

[0036] In some embodiments, multiple bodies 2 may be provided, each of which has a different gap width and is used to detect thin plate parts of different thicknesses. That is, when detecting thin plate parts of different thicknesses, the corresponding body 2 may be replaced on the bottom plate 1.

[0037] In some embodiments, the gap of the detection area 21 can be configured to be adjustable. In this embodiment, the main body 2 can be split. For example, the main body 2 can include two main body halves, between which the gap is formed, and the two main body halves can move relative to each other so that the width of the gap changes with the movement of the main body halves. In some embodiments, the width adjustment of the gap can be achieved by rotating the adjusting screw in the internal threaded hole in the main body half.

[0038] In some embodiments, the guide portion 22 may be located above the detection area 21. The guide portion 22 may include at least one inclined guide surface 221. The inclined guide surface 221 of the guide portion 22 may lead to the gap of the detection area 21 and form an angle with the corresponding side wall of the gap. The inclined guide surface 221 and the side wall of the gap of the detection area 21 form a certain angle, so that the inclined guide surface 221 can more easily guide the thin plate-shaped parts to be used to slide into the gap of the detection area 21. In some embodiments, the upper end surface of the guide portion 22 is configured as a plane to avoid the inclined guide surface 221 and the side wall of the main body 2 directly intersecting to form a sharp acute angle, thereby avoiding the potential safety hazards caused by this. In some embodiments, as Figure 1 and Figure 2 As shown, the guide portion 22 may include two inclined guide surfaces 221. The two inclined guide surfaces 221 may be symmetrically arranged relative to the gap, so that the two inclined guide surfaces 221 may present a cross-sectional shape such as a V-shape, a U-shape, or a parabola. In some embodiments, the inclined guide surface 221 is arranged only on one side of the gap of the detection area 21, and the other side is a plane extending along the side wall of the gap.

[0039] In some embodiments, the body 2 is made of metal. The transition portion where the inclined guide surface 221 of the guide portion 22 intersects the side wall of the gap of the detection area 21 can be heat treated to make it more wear-resistant. In some embodiments, the inclined guide surface 221 of the guide portion 22 and the side wall of the gap of the detection area 21 can be connected to each other via a rounded transition portion that has been rounded to avoid the presence of sharp edges and the resulting mutual wear of parts.

[0040] In an embodiment according to the present disclosure, the sensor may be configured to detect whether the sheet-shaped part to be used enters the gap of the detection area 21, and when the sheet-shaped part to be used enters the gap, the sensor is triggered, and when the sheet-shaped part to be used does not enter the gap, the sensor is not triggered. The sensor may be installed in the sensor installation hole 23. Figure 2 As shown, the sensor mounting hole 23 can be located on the first side of the gap and can be constructed as a through hole leading to the gap. The through hole may include two sections, namely: a first section 231 with a smaller diameter and a second section 232 with a larger diameter. A step portion is formed between the first section 231 and the second section 232. The sensor can be installed in the first section 231, and the sensing element of the sensor can face the gap. In some embodiments, the end face of the sensor facing the gap is installed to be 2-3mm away from the step. In some embodiments, the outer periphery of the sensor can be provided with an external thread, and the interior of the sensor mounting hole 23 can be provided with an internal thread, and the sensor can be installed in the sensor mounting hole 23 by screwing.

[0041] In some embodiments, the sensor may be an inductive sensor, such as a proximity sensor. In these embodiments, the body 2 further includes a second through hole located at a second side of the gap opposite to the first side. The second through hole may lead to the gap and be substantially coaxial with the sensor mounting hole 23. The presence of the second through hole may allow the inductive signal emitted by the inductive sensor to pass unimpeded, thereby enabling the inductive sensor to operate normally.

[0042] In some embodiments, the transition portion between the inclined guide surface 221 and the gap sidewall of the detection area 21 is higher than the highest point of the sensor's sensing range. This structure makes it impossible for the thin plate-shaped part that is not inserted into the gap of the detection area 21 to trigger the sensor's sensing, and the sensor's sensing can only be triggered after the thin plate-shaped part is actually inserted into the gap of the detection area 21.

[0043] In some embodiments, the detection device may include an alarm. The alarm may be connected to the sensor by wired or wireless signal. The alarm may be configured as follows: if the thin plate-shaped part has not been detected by the detection area 21 of the main body 2, that is, the sensor has not been triggered to sense, then once the thin plate-shaped part enters the subsequent processing step, the alarm will sound an alarm; if the thin plate-shaped part has been detected by the detection area 21 of the main body 2, that is, the sensor has been triggered to sense, then when the thin plate-shaped part enters the subsequent processing step, the alarm will no longer sound an alarm. After the loading of the thin plate-shaped part is completed, before the detection of the next thin plate-shaped part is performed, the trigger record of the sensor is eliminated, that is, when the next thin plate-shaped part is loaded onto the production fixture for welding, the alarm cannot be eliminated by relying on the sensor trigger record of the previous detection cycle.

[0044] In some embodiments, the alarm signal of the alarm may include a visual alarm signal or an audible alarm signal. In some embodiments, the alarm signal of the alarm may have multiple types, corresponding to different fault contents, wherein one type corresponds to failure to pass the anti-overlap detection.

[0045] Next, combine Figure 1 and Figure 2The use process of the detection device for preventing the loading of overlapping parts is described. After picking up the thin plate-shaped parts to be used and before using them in the subsequent process, the thin plate-shaped parts to be used must first be detected using the detection device for preventing the loading of overlapping parts. Specifically, one end of the thin plate-shaped part is delivered to the gap of the detection area 21 (for example, delivered to the gap of the detection area 21 along the inclined guide surface 221). If the thin plate-shaped part enters the gap of the detection area 21, it can be determined that the thin plate-shaped part is a single thin plate-shaped part; if the thin plate-shaped part cannot enter the gap of the detection area 21, it can be determined that the thin plate-shaped part is an overlapping thin plate-shaped part. The overlapping thin plate-shaped parts can be separated from each other, and then the anti-overlapping detection can be performed again.

[0046] The thin plate parts that have passed the anti-overlapping test can proceed to the subsequent process. If the alarm is triggered when entering the subsequent process, it means that the operator forgot to perform the anti-overlapping test, or the thin plate parts did not pass the anti-overlapping test. In this case, return to the anti-overlapping test.

[0047] Although the exemplary embodiments of the present disclosure have been described, it should be understood by those skilled in the art that various changes and modifications can be made to the exemplary embodiments of the present disclosure without departing from the spirit and scope of the present disclosure in essence. Therefore, all changes and modifications are included in the scope of protection of the present disclosure as defined by the claims.
