Testing equipment and material rack return line

Abstract

This utility model provides a detection device and a material rack return line. The detection device includes a mounting body, a sensor, and a detection component. The mounting body is mounted on a clamping mechanism. The sensor is mounted on the mounting body and has a sensing position. The detection component is movably mounted on the mounting body and extends from the bottom wall of the mounting body. The detection component is used for communication connection with the clamping mechanism. When the clamping mechanism descends to clamp the material rack, and there is material in the rack, the detection component descends with the clamping mechanism and comes into contact with the material in the rack. The detection component is then lifted and moved along the first direction to the sensing position to trigger the sensor. The sensor generates a trigger signal and transmits it to the clamping mechanism to control the clamping mechanism to stop. On-site personnel can then confirm whether there is material in the rack, preventing the clamping mechanism from clamping a rack with material, which could cause the material to tip over and fall, reducing material loss, and helping to reduce costs and increase efficiency, thus improving the practicality of the detection device and the material rack return line.

Description

Technical Field

[0001] This utility model relates to the field of detection technology, and in particular to a detection device and a material rack return line. Background Technology

[0002] In the cleaning workshop of a slicing plant, automated guided vehicles (AGVs) are typically used to automatically transport shelves containing degumming racks. When an AGV docks with a shelf, it identifies the shelf's number and checks its task location and the status of the materials inside. However, when AGVs encounter abnormal situations such as task errors, incorrect material status, or human error causing the shelves to be pushed, the AGV may deliver a shelf with materials to the degumming return line. Consequently, when the robotic arm on the return line grabs the degumming rack, the materials may tip over and fall, resulting in losses. Utility Model Content

[0003] Therefore, it is necessary to provide a detection device and a material rack return line to address the above problems.

[0004] The technical solution is as follows:

[0005] On one hand, a detection device is provided, installed on the clamping mechanism of the material rack return line, and used to detect whether there is material when the material rack returns to the basket. The detection device includes:

[0006] The mounting body is mounted on the clamping mechanism;

[0007] A sensing element is mounted on the mounting body and has a sensing position;

[0008] A detection component is movably mounted on the mounting body along a first direction that forms an angle with the horizontal plane and extends from the bottom wall of the mounting body. The detection component is used to communicate with the clamping mechanism.

[0009] When the clamping mechanism descends to clamp the material rack and there is material in the material rack, the detection component comes into contact with the material and is lifted and moved along the first direction to the sensing position to trigger the sensing element. When the clamping mechanism descends to clamp the material rack and there is no material in the material rack, the detection component moves to the bottom of the material rack and the detection component does not trigger the sensing element.

[0010] The technical solution will be further explained below:

[0011] In one embodiment, when the clamping mechanism descends to clamp the rack and there is no material in the rack, the detection component passes through the rack and moves to abut against the bearing surface used to support the rack. The detection component is located below the sensing position so as not to trigger the sensor.

[0012] In one embodiment, the detection component includes a trigger, a movable member, and an abutment member. The trigger is mounted on the top of the movable member and is used to trigger the sensing member. The movable member moves and engages with the mounting body along the first direction. The bottom end of the movable member extends from the bottom wall of the mounting body and connects with the abutment member.

[0013] In one embodiment, the outer side wall of the mounting body is provided with a groove extending along the first direction and a mounting hole communicating with the groove, the sensing element is mounted in the mounting hole, and the trigger element extends at least partially into the groove.

[0014] In one embodiment, the first direction is set to a vertical direction, the bottom wall of the mounting body is provided with a guide hole extending in the vertical direction, the moving member passes through the guide hole and is guided and engaged with the inner side wall of the guide hole, and the trigger member is further configured to limit the engagement with the end face of the guide hole away from the abutment member when the abutment member is in a suspended state.

[0015] In one embodiment, the bottom wall of the mounting body is further provided with a guide sleeve communicating with the guide hole, the guide sleeve being configured to guide and cooperate with the moving member when the moving member passes through the guide sleeve.

[0016] In one embodiment, the detection component further includes an elastic element mounted between the abutment and the mounting body, configured to elastically deform when the abutment is lifted to store an elastic force that drives the abutment to reset.

[0017] In one embodiment, the elastic element is configured as a spring, which is sleeved on the outer side wall of the movable element, and the two ends of the spring contact the abutment element and the mounting body, respectively.

[0018] On the other hand, a rack return line is provided, including a transport device, a clamping mechanism and the detection device, wherein the clamping mechanism is configured to clamp the rack when the transport device transports the rack to a position directly below the clamping mechanism.

[0019] In one embodiment, the clamping mechanism is provided with a fastener, the mounting body is inserted through the fastener, and the fastener is configured to be fastened to the mounting body when the mounting body is adjusted to a preset height relative to the clamping mechanism.

[0020] In the detection device and material rack return line described in the above embodiments, when the clamping mechanism descends to clamp the material rack, if there is no material in the rack, the detection component descends synchronously with the clamping mechanism and moves to the bottom of the rack. At this time, the detection component does not trigger the sensor, and the clamping mechanism clamps the rack and returns the rack. If there is material in the rack, the detection component descends synchronously with the clamping mechanism and comes into contact with the material in the rack. As the clamping mechanism descends further, the detection component is lifted to the sensing position to trigger the sensor. The sensor generates a trigger signal and transmits it to the host computer. The host computer controls the clamping mechanism to stop according to the trigger signal. On-site personnel confirm whether there is material in the rack, avoiding the clamping mechanism from clamping a rack with material, which could cause the material to tip over and fall, reducing material loss, and helping to reduce costs and increase efficiency, thus improving the practicality of the detection device and material rack return line.

[0027] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0028] like Figure 1 and Figure 2 As shown, in one embodiment, a detection device 10 is provided, mounted on a clamping mechanism 20 of a material rack return line, and used to detect whether there is material when the material rack returns to the basket. The detection device 10 includes a mounting body 100, a sensor 200, and a detection component 300. The mounting body 100 is mounted on the clamping mechanism 20. The sensor 200 is mounted on the mounting body 100 and has a sensing position. The detection component 300 is movably mounted on the mounting body 100 along a first direction at an angle to the horizontal plane and extends from the bottom wall of the mounting body 100. The detection component 300 is used for communicative connection with the clamping mechanism 20. When the clamping mechanism 20 lowers to clamp the material rack and there is material in the rack, the detection component 300 comes into contact with the material and is lifted and moved along the first direction to the sensing position to trigger the sensor 200. When the clamping mechanism 20 lowers to clamp the material rack and there is no material in the rack, the detection component 300 moves to the bottom of the rack, and the detection component 300 does not trigger the sensor 200.

[0029] In the above embodiment, when the clamping mechanism 20 lowers to clamp the material rack, if there is no material in the rack, the detection component 300 lowers synchronously with the clamping mechanism 20 and moves to the bottom of the rack. At this time, the detection component 300 does not trigger the sensor 200, and the clamping mechanism 20 clamps the rack and returns to the basket. If there is material in the rack, the detection component 300 lowers synchronously with the clamping mechanism 20 and comes into contact with the material in the rack. As the clamping mechanism 20 lowers further, the detection component 300 is lifted to the sensing position to trigger the sensor 200. The sensor 200 generates a trigger signal and transmits it to the host computer. The host computer controls the clamping mechanism 20 to stop according to the trigger signal. On-site personnel confirm whether there is material in the rack, avoiding the clamping mechanism 20 from clamping a rack with material and causing the material to tip over and fall, reducing material loss, which is conducive to cost reduction and efficiency improvement, and improving the practicality of the detection device 10.

[0030] In this specific embodiment, the material rack is set as a debonding rack, and the corresponding material is a silicon wafer.

[0031] The mounting body 100 can be configured as a mounting bracket, mounting base, mounting rod, or other mounting structure. The sensing element 200 can be configured as a proximity switch, infrared sensor, or other sensing device.

[0032] The angle between the first direction and the horizontal plane can be flexibly adjusted according to actual usage needs. For example, the angle between the first direction and the horizontal plane can be set to 60° to 90°.

[0033] Specifically, in this embodiment, the detection device 10 also includes an alarm component (e.g., an alarm light or alarm) that is communicatively connected to the detection component 300. Thus, the trigger signal generated when the sensor 200 is triggered is also transmitted to the alarm component, which then sounds an alarm to notify on-site personnel to confirm whether there is material in the material rack.

[0034] Optionally, when the clamping mechanism 20 lowers to clamp the material rack and there is no material in the rack, the detection component 300 passes through the rack and moves to abut against the bearing surface used to support the rack. The detection component 300 is positioned below the sensing position so as not to trigger the sensor 200. In this way, by using the detection component 300 to pass through the rack to detect whether there is material in the rack, the presence of material in the rack will trigger the sensor 200, thus improving the reliability of the detection device 10.

[0035] It should be noted that the lifting force generated when the detection component 300 comes into contact with the material and the lifting force generated when the detection component 300 comes into contact with the bearing surface have been verified and calculated to ensure that the sensor 200 is triggered when the detection component 300 comes into contact with the material, but is not triggered when the detection component 300 comes into contact with the bearing surface.

[0036] In other embodiments, the detection component 300 may not abut against the bearing surface (e.g., only contact the bearing surface), as long as the detection component 300 passes through the area where the lowest material is placed in the rack.

[0037] like Figure 2 As shown, in one embodiment, the detection assembly 300 includes a trigger 310, a movable member 320, and an abutment 330. The trigger 310 is mounted on the top of the movable member 320 and is used to trigger the sensor 200. The movable member 320 is movablely engaged with the mounting body 100 in a first direction. The bottom end of the movable member 320 extends from the bottom wall of the mounting body 100 and connects with the abutment 330. Thus, the trigger 310, the movable member 320, and the abutment 330 can be pre-processed separately and then assembled into the detection assembly 300 and mounted on the mounting body 100, improving the ease of manufacturing the detection device 10.

[0038] The trigger element 310 can be configured as a trigger post, trigger block, trigger plate, or other triggering structure. The moving element 320 can be configured as a moving rod, moving tube, or other moving structure. The abutting element 330 can be configured as an abutting plate, abutting disc, abutting seat, or other abutting structure. Specifically, in this embodiment, the moving element 320 is arranged in a vertical direction.

[0039] like Figure 2As shown, optionally, the outer wall of the mounting body 100 is provided with a groove 110 extending along a first direction and a mounting hole communicating with the groove 110. The sensor 200 is mounted in the mounting hole. The trigger 310 extends at least partially into the groove 110. In this way, the sensing position is located within the groove 110, allowing the mounting body 100 to isolate the sensing position from the external environment, effectively reducing the possibility of the sensor 200 being falsely triggered and improving the reliability of the detection device 10.

[0040] Specifically, in this embodiment, the trigger 310 moves and engages with the inner wall of the groove 110 along the first direction. Thus, the mounting body 100 can guide the moving part 320 via the trigger 310, ensuring that the moving part 320 can move stably and reliably along the first direction, thereby improving the reliability of the detection device 10.

[0041] In one embodiment, the first direction is set to vertical. The bottom wall of the mounting body 100 has a guide hole extending vertically. The moving member 320 passes through the guide hole and is guided and engaged with the inner wall of the guide hole. The trigger member 310 is also configured to limit the movement of the guide hole on the side away from the abutment member 330 when the abutment member 330 is in a suspended state. Thus, the abutment member 330 can cooperate with the trigger member 310 to limit the movement of the moving member 320, ensuring that the moving member 320 does not dislodge from the guide hole and improving the reliability of the detection device 10.

[0042] Optionally, the bottom wall of the mounting body 100 is further provided with a guide sleeve 120 communicating with the guide hole. The guide sleeve 120 is configured to guide and cooperate with the moving member 320 when the moving member 320 passes through the guide sleeve 120. In this way, the guide sleeve 120 can increase the contact area between the mounting body 100 and the moving member 320, ensuring that the moving member 320 can move stably and reliably in the vertical direction, thereby improving the reliability of the detection device 10.

[0043] In this specific embodiment, the guide sleeve 120 and the mounting body 100 are integrally formed.

[0044] like Figure 2 As shown, in one embodiment, the detection assembly 300 further includes an elastic element 340. The elastic element 340 is installed between the abutment 330 and the mounting body 100, and is configured to elastically deform when the abutment 330 is lifted to store the elastic force driving the abutment 330 to reset. Thus, by applying an elastic force to the abutment 330 through the elastic element 340, it is ensured that the abutment 330, the moving element 320, and the trigger element 310 can all reset after a single detection, thereby ensuring that the detection assembly 300 can cyclically detect whether there is material when the material rack returns to the basket, improving the reliability of the detection device 10.

[0045] The elastic element 340 can be configured as an elastic washer, spring, elastic post, or other elastic connection. The number of elastic elements 340 can be flexibly adjusted according to actual usage requirements.

[0046] like Figure 2 As shown, optionally, the elastic element 340 is a spring. The spring is sleeved on the outer wall of the moving element 320. The two ends of the spring contact the abutment 330 and the mounting body 100, respectively. In this way, the moving element 320 can guide the spring, ensuring that the spring can stably and reliably extend and retract in the vertical direction and provide elastic force for resetting to the abutment 330, thereby improving the reliability of the detection device 10.

[0047] It should be noted that when the abutment 330 is in a suspended state, the spring can remain in a natural state or a compressed state.

[0048] In other embodiments, the number of elastic elements 340 may be at least two, with each elastic element 340 spaced apart around the axis of the moving member 320 and installed between the mounting body 100 and the abutment member 330.

[0049] In one embodiment, a rack return line is also provided, including a transport device, a clamping mechanism 20, and a detection device 10 as described in any of the above embodiments, wherein the clamping mechanism 20 is configured to clamp the rack when the transport device transports the rack to a position directly below the clamping mechanism 20.

[0050] In the above embodiment of the material rack return line, during use, the transport device transports the material rack to directly below the clamping mechanism 20. When the clamping mechanism 20 descends to clamp the material rack, if there is no material in the rack, the detection component 300 descends synchronously with the clamping mechanism 20 and moves to the bottom of the rack. At this time, the detection component 300 does not trigger the sensor 200, and the clamping mechanism 20 clamps the rack and returns it to the basket. If there is material in the rack, the detection component 300 descends synchronously with the clamping mechanism 20 and comes into contact with the material in the rack. As the clamping mechanism 20 descends further, the detection component 300 is lifted to the sensing position to trigger the sensor 200. The sensor 200 generates a trigger signal and transmits it to the host computer. The host computer controls the clamping mechanism 20 to stop according to the trigger signal. On-site personnel then confirm whether there is material in the rack, preventing the clamping mechanism 20 from clamping a rack with material and causing the material to tip over and fall, reducing material loss, which is beneficial for cost reduction and efficiency improvement, and enhancing the practicality of the material rack return line.

[0051] Optionally, the clamping mechanism 20 is provided with a fastener. The mounting body 100 passes through the fastener. The fastener is configured to securely engage with the mounting body 100 when the mounting body 100 is adjusted to a preset height relative to the clamping mechanism 20. In this way, the height of the detection device 10 relative to the clamping mechanism 20 is adjustable, so as to be applicable to the detection of whether there is material on different types of material racks, thereby improving the practicality of the material rack return line.

[0052] The preset height can be flexibly adjusted according to actual usage needs. Fasteners can be set as fastening clamps, fastening hoops, or other fastening structures.

[0053] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0054] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0055] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0056] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0057] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0058] It should also be understood that, in interpreting the connection or positional relationships of components, although not explicitly described, connection and positional relationships are interpreted to include a range of error, which should be within the acceptable deviation range of a specific value as determined by a person skilled in the art. For example, "approximately," "about," or "substantially" can mean within one or more standard deviations, without limitation herein.

[0059] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0060] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
