Description

Technical Field

[0001] This application relates to the field of material testing technology, specifically to a material testing device and production line. Background Technology

[0002] During production, production lines often need to be equipped with mirror-reflective photoelectric sensors to detect whether materials have been transferred to a specific location.

[0003] In the prior art, a specular reflection photoelectric sensor includes a photoelectric switch and a reflector. The photoelectric switch can emit a detection beam. When the detection beam is accurately reflected back to the photoelectric switch by the reflector, it can be assumed that there is no material in the transmission path of the detection beam and the material has not been transmitted to the specific position. When there is material in the path of the detection beam, causing the detection beam to be unable to be transmitted to the reflector and reflected back to the photoelectric switch, it can be assumed that the material has been transmitted to the specific position.

[0004] However, both the photoelectric switch and the reflector are bolted to the production line frame via mounting bases. Before actual use of the mirror reflection photoelectric sensor, it needs to be debugged. The position of the photoelectric switch needs to be adjusted so that it is directly facing the material at a specific location. The position of the reflector also needs to be adjusted accordingly so that it is directly facing the photoelectric switch. When the material is not transported to the specific location, the detection beam emitted by the photoelectric switch can be reflected back to the photoelectric switch by the reflector. Therefore, the operator needs to repeatedly tighten the bolts of the photoelectric switch mounting base and the reflector mounting base to adjust the position of the photoelectric switch and the reflector, making the debugging process of the mirror reflection photoelectric sensor cumbersome and difficult.

[0005] Therefore, there is an urgent need for a material testing device and production line to solve the above problems. Utility Model Content

[0006] The purpose of this application is to solve or at least alleviate some or all of the aforementioned problems. Therefore, the purpose of this application is to provide a material detection device and production line that simplifies the adjustment process of a specular reflection photoelectric sensor and reduces the difficulty of debugging.

The first clamping portion and the second clamping portion are corresponding to each other and spaced apart. The first clamping portion has a first connecting hole, and the second clamping portion has a first threaded hole. The first bolt passes through the first connecting hole and is threadedly engaged with the first threaded hole. By tightening the first bolt, the first clamping portion and the second clamping portion can be deformed and brought closer together to clamp the first end of the third connecting rod. The photoelectric switch and the reflector are respectively fixedly connected to the two first mounting portions.

[0016] Preferably, the first end of the first connecting rod is rotatably connected to the first mounting component with its own axis as the axis.

[0020] Preferably, the limiting component includes a first limiting connector and a second limiting connector. Two third connecting holes are also spaced apart along the length of the bottom wall of the slide groove. A fixing hole corresponding to the third connecting hole is provided on the frame.

[0038] Before explaining any implementation of this application in detail, it should be understood that this application is not limited to its application to the structural details and component arrangements set forth in the following description or shown in the above drawings.

[0039] In this application, the terms "comprising," "including," "having," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0040] In this application, the term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this application generally indicates that the preceding and following related objects have an "and / or" relationship.

[0041] In this application, the terms "connection," "combination," "coupling," and "installation" can refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, a direct connection refers to two parts or components being connected together without the need for an intermediary, while an indirect connection refers to two parts or components each being connected to at least one intermediary, with the connection achieved through the intermediary. Furthermore, "connection" and "coupling" are not limited to physical or mechanical connections or couplings, but can also include electrical connections or couplings.

[0042] In this application, those skilled in the art will understand that relative terms (e.g., “about,” “approximately,” “basically,” etc.) used in conjunction with quantities or conditions are to include the values ​​and have the meaning indicated by the context. For example, such relative terms include at least the degree of error associated with the measurement of a particular value, tolerances associated with the particular value due to manufacturing, assembly, use, etc. Such terms should also be considered as disclosing a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​not using relative terms should also be disclosed as specific values ​​with tolerances. Furthermore, “basically” when expressing relative angular relationships (e.g., substantially parallel, substantially perpendicular) may refer to a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) added to or subtracted from the indicated angle.

[0043] In this application, those skilled in the art will understand that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one component, or a combination of multiple parts.

[0044] In this application, the directional terms "upper," "lower," "left," "right," "front," and "rear" are used to describe the orientation and positional relationships shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when an element is mentioned as being connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected through an intermediate element. It should also be understood that directional terms such as upper side, lower side, left side, right side, front side, and rear side not only represent positive orientation but can also be understood as lateral orientation. For example, "below" can include directly below, lower left, lower right, lower front, and lower rear.

[0045] When debugging the specular reflection photoelectric sensor, because both the photoelectric switch and the reflector are bolted to the production line frame via mounting brackets, operators need to repeatedly tighten and loosen the bolts to adjust the positions of the photoelectric switch and reflector 3. This makes the debugging process of the specular reflection photoelectric sensor quite cumbersome. Therefore, changing the connection relationship between the photoelectric switch, the reflector, and the production line frame is the key to solving the above technical problems. The following section combines... Figures 1 to 4 The material detection device provided in this embodiment will be described in detail.

[0046] Figure 1 This diagram shows the structure of the material detection device provided in this embodiment installed on the frame 100 in the first direction. Figure 2 This diagram illustrates the structure of the material detection device provided in this embodiment installed on the frame 100 in the second direction. (See attached diagram.) Figures 1 to 2 As shown, the material detection device provided in this embodiment is installed on the frame 100 of the production line and is used to detect materials conveyed to the detection position. The material detection device includes two mounting brackets 1, a photoelectric switch 2, and a reflector 3. The two mounting brackets 1 are respectively installed on the frame 100 and located on both sides of the material conveying direction of the production line. The photoelectric switch 2 is rotatably connected to the first mounting bracket 1, and the reflector 3 is rotatably connected to the second mounting bracket 1. Both the photoelectric switch 2 and the reflector 3 can rotate so that the photoelectric switch 2 faces the reflector 3. It should be noted that the material detection device provided in this embodiment realizes the detection of materials by installing a specular reflection photoelectric sensor on the mounting bracket 1. When using the material detection device, the photoelectric switch 2 must always face the reflector 3 so that the detection beam emitted by the photoelectric switch 2 can be transmitted to the reflector 3 and reflected back to the photoelectric switch 2. The photoelectric switch 2 can receive the detection beam and feed back an electrical signal.

[0047] The material detection device provided in this embodiment, by installing two mounting brackets 1 on the frame 100 respectively, allows the photoelectric switch 2 to be rotatably connected to the first mounting bracket 1 and the reflector 3 to be rotatably connected to the second mounting bracket 1. Thus, when debugging the photoelectric switch 2 and the reflector 3 of the material detection device, the photoelectric switch 2 can be rotated to face the material located at the detection position, and the reflector 3 can be rotated to face the photoelectric switch 2. Therefore, it is not necessary to repeatedly tighten the bolts of the mounting base of the photoelectric switch 2 and the mounting base of the reflector 3 to adjust the position of the photoelectric switch 2 and the reflector 3, simplifying the debugging process and reducing the debugging difficulty.

[0048] Figure 3 It shows Figure 1 A magnified view of a portion of point A in the diagram. (See diagram below.) Figure 3 Combination Figures 1 to 2As shown, the mounting bracket 1 includes a first mounting component 11 and a mounting rod 12. The first mounting component 11 is mounted on the frame 100. One end of the mounting rod 12 is connected to the first mounting component 11. The photoelectric switch 2 and the reflector 3 are respectively rotatably connected to the other ends of the two mounting rods 12, so that the photoelectric switch 2 and the reflector 3 can be supported at a specific height, thereby detecting materials at a specific height.

[0049] In this embodiment, the mounting rod 12 includes a first connecting rod 121, a second connecting rod 122, and a third connecting rod 123. The first end of the first connecting rod 121 is connected to the first mounting member 11, and the second end is connected at an angle to the first end of the second connecting rod 122. The photoelectric switch 2 and the reflector 3 are rotatably connected to the first ends of the two third connecting rods 123, respectively. The second ends of the third connecting rods 123 are connected at an angle to the second end of the second connecting rod 122. The axes of the first connecting rod 121 and the third connecting rod 123 are arranged parallel, thereby increasing the distance between the photoelectric switch 2 and the material to be detected, as well as the distance between the reflector 3 and the material. When rotating the photoelectric switch 2 and the reflector 3, a larger material detection range can be provided with the same rotation amplitude.

[0050] Figure 4 An exploded view of the mounting bracket 1 provided in this embodiment is shown, as follows: Figure 4 Combination Figures 1 to 2 As shown, the mounting bracket 1 also includes a second mounting component 13, which has a first mounting portion 131, a first clamping portion 132, a second clamping portion 133, and a first bolt 134. The first clamping portion 132 and the second clamping portion 133 are respectively connected to the first mounting portion 131. The first clamping portion 132 and the second clamping portion 133 are corresponding to each other and spaced apart. The first clamping portion 132 has a first connecting hole, and the second clamping portion 133 has a first threaded hole. The first bolt 134 passes through the first connecting hole and is threaded into the first threaded hole. By tightening the first bolt 134, the first clamping portion 132 and the second clamping portion 133 can be connected. The photoelectric switch 2 and the reflector 3 are respectively fixedly connected to the two first mounting parts 131, so that the second mounting part 13 can clamp the first end of the third connecting rod 123 of the mounting rod 12. When the material is too low and the photoelectric switch 2 cannot face the material, the first bolt 134 can be turned to restore the original shape of the first clamping part 132 and the second clamping part 133. The second mounting part 13 can slide along the axial direction of the third connecting rod 123 to adjust the height of the photoelectric switch 2 and the reflector 3, so that the photoelectric switch 2 and the reflector 3 can detect materials of different heights.

[0051] Preferably, the first clamping part 132 has a first arc-shaped clamping surface, and the second clamping part 133 has a second arc-shaped clamping surface. Both the first arc-shaped clamping surface and the second arc-shaped clamping surface match the outer side wall of the third connecting rod 123 of the mounting rod 12. When the first clamping part 132 and the second clamping part 133 clamp the first end of the third connecting rod 123, the first arc-shaped clamping surface and the second arc-shaped clamping surface form a clamping space for clamping the first end of the third connecting rod 123, thereby enhancing the stability of the first clamping part 132 and the second clamping part 133 in clamping the third connecting rod 123.

[0052] like Figure 3 Combination Figures 1 to 2 As shown, the first end of the first connecting rod 121 is rotatably connected to the first mounting member 11 about its own axis. Specifically, the first mounting member 11 has a second mounting part 111, a third clamping part 112, a fourth clamping part 113, and a second bolt 114. The second clamping part 113 and the third clamping part 112 are respectively connected to the second mounting part 111. The third clamping part 112 and the fourth clamping part 113 are corresponding to each other and spaced apart. The third clamping part 112 has a second connecting hole, and the fourth clamping part 113 has a second threaded hole. The second bolt 114 passes through the second connecting hole and is threadedly engaged with the second threaded hole. By tightening the second bolt 114, both the third clamping part 112 and the fourth clamping part 113 can be deformed to clamp the first end of the first connecting rod 121.

[0053] like Figure 4 Combination Figures 1 to 3 As shown, the mounting bracket 1 also includes a third mounting member 14, which is fixedly connected to the frame 100. The first mounting member 11 is slidably connected to the third mounting member 14 along the material conveying direction, thereby increasing the adjustment range of the photoelectric switch 2 and the reflector 3 while maintaining low debugging difficulty. Specifically, the third mounting member 14 has a groove 141 extending along the material conveying direction, and the first mounting member 11 has a slider 115 that slides in cooperation with the groove 141, thereby guiding the movement direction of the first mounting member 11 and preventing directional deviation when the first mounting member 11 slides along the material conveying direction.

[0054] In some embodiments, the slider 115 can also be a T-nut, which is fixedly connected to the first mounting member 11 by bolts, so that the T-nut can slide in the groove 141, and the first mounting member 11 can slide along the material conveying direction.

[0055] Continue as Figure 4 Combination Figures 1 to 3As shown, the material detection device also includes a limiting component 4, which is used to limit the sliding of the first mounting member 11 along the material conveying direction, so that the first mounting member 11 can be limited to sliding within a specific range, thereby limiting the position adjustment range of the photoelectric switch 2 and the reflector 3. Specifically, the limiting component 4 includes a first limiting connector 41 and a second limiting connector 42. Two third connecting holes 142 are also spaced apart on the bottom wall of the slide groove 141 along its own length direction. The frame 100 is provided with fixing holes corresponding to the third connecting holes 142. The first limiting connector 41 passes through one third connecting hole 142 and is connected to the fixing hole corresponding to the third connecting hole 142. The second limiting connector 42 passes through the other third connecting hole 142 and is connected to the fixing hole corresponding to the third connecting hole 142. Both the first limiting connector 41 and the second limiting connector 42 protrude from the slide groove 141. The first mounting member 11 is located between the first limiting connector 41 and the second limiting connector 42. Thus, while fixing the third mounting member 14 to the frame 100, it can also limit the sliding of the first mounting member 11 along the material conveying direction to a specific range and prevent the slider 115 from disengaging from the slide groove 141, causing the first mounting member 11 to separate from the third mounting member 14.

[0056] This embodiment also provides a production line, including the above-mentioned material detection device and frame 100. The material detection device is installed on the frame 100, thereby enabling it to detect the material being transferred to the detection position.

[0057] The foregoing has shown and described the basic principles, main features, and advantages of this application. Those skilled in the art should understand that the above embodiments do not limit this application in any way, and all technical solutions obtained by equivalent substitution or equivalent transformation fall within the protection scope of this application.
