Abstract
Description
Technical Field
[0001] This utility model belongs to the field of mechanical testing technology, specifically relating to a floating positioning testing mechanism and device. Background Technology
[0002] Before being put into practical use, products need to undergo various performance tests. They are typically conveyed to the required position on a conveyor line and then picked up by a robotic arm and taken to the testing station for testing. Many products have irregular shapes, and to avoid unnecessary scratches on the product's appearance during robotic arm handling, which would affect the yield rate, targeted point-to-point gripping is required for products of different specifications. To detect whether the product has been conveyed correctly, existing testing methods generally place corresponding sensors at the gripping position. However, due to the wide variety of product types and shapes, multiple sensors are required. Furthermore, during the robotic arm gripping process, the instability of the product placed directly on the conveyor line can easily lead to slippage of the gripping position, resulting in errors in the final gripping position and causing unnecessary wear on the product surface. For products with strict requirements on appearance and structure, this can affect their yield rate. Utility Model Content
[0003] To address the shortcomings of existing technologies, this utility model provides a floating positioning detection mechanism and device that can accurately position the product to be detected, with high positioning stability and high adaptability.
[0004] The objective of this utility model is achieved through the following technical solution:
[0005] A floating positioning and detection mechanism includes a linear drive mechanism, a positioning component and a detection component located at one end of the linear drive mechanism, the detection component being located on one side of the positioning component, the detection component being flexibly connected to the linear drive mechanism, and the positioning component being detachably connected to the linear drive mechanism. When the linear drive mechanism is in operation, it drives the positioning component and the detection component to reciprocate.
[0006] Preferably, the linear drive mechanism is a slide cylinder, and the positioning component and the detection component are located at the far end of the slide of the slide cylinder.
[0007] Preferably, the positioning component is a contour block that matches the product to be tested, and the distal end of the contour block has a built-in magnetic component.
[0008] Preferably, the detection component includes a base plate placed at the far end of the slide table and a contact plate placed at the front end of the base plate connected by a spring. The base plate is provided with a sensing element. When the contour block attracts the product to be detected by the built-in magnetic element, the product to be detected will simultaneously abut against the contact plate and compress the spring.
[0009] Preferably, the sensing element is a proximity sensor.
[0010] Preferably, the contouring component is connected to the base via a quick-change connector, and the base is fixed to the far end of the slide table.
[0011] Preferably, an apparatus having any one of the above floating positioning and detection mechanisms includes a conveyor line and a floating positioning and detection mechanism disposed at the end of the conveyor line, wherein the linear drive mechanism of the floating positioning and detection mechanism drives the positioning component and the detection component to reciprocate in the product direction.
[0012] Preferably, the conveyor line is a chain conveyor line.
[0013] The beneficial effects of this utility model are as follows: it can quickly and stably position the product to be tested, avoiding displacement during the testing process that could lead to incorrect gripping position and unnecessary wear on the product's appearance. Furthermore, by replacing the contour block, it can be applied to products of different models and shapes, making it highly adaptable. Attached Figure Description
[0014] To more clearly illustrate the technical solutions of the embodiments of this utility model, the drawings used in the description of the embodiments will be briefly introduced below. Obviously, the drawings described below are some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0018] This utility model proposes a floating positioning detection mechanism and device. To make the purpose, technical solution, and advantages of this utility model clearer, the following description is in conjunction with the appendix. Figures 1-3 The present invention will be further described in detail below with reference to embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.
[0019] Combination Figure 1As shown, a floating positioning and detection mechanism includes a linear drive mechanism 1, a positioning component and a detection component connected to one end of the linear drive mechanism 1. When the linear drive mechanism is in operation, it drives the positioning component and the detection component to reciprocate. The positioning component is used to adsorb and position the product to be detected, and the detection component on one side monitors its position.
[0020] In this embodiment, the linear drive mechanism 1 is a slide cylinder, and the positioning component and the detection component are located at the far end of the slide 2 of the slide cylinder 1. To avoid rigid contact between the product and the detection mechanism, the detection component and the linear drive mechanism are flexibly connected. The detection component includes a base plate located at the far end of the slide 2 and a contact plate 3 located at the front end of the base plate connected by a spring 31. A sensor 32 is provided inside the base plate. The sensor 32 is a proximity sensor, and a set of springs 31 is provided. When the contact plate 3 is pressed, it compresses the spring 31 and moves it towards the base plate, and the proximity sensor generates a sensing signal. There is one sensor 32, and the contact plate 3 is plate-shaped with a large contact area. When any position of the product contacts any position of the contact plate 3 and compresses the spring 31, the sensor 32 can be triggered to work. Compared with traditional detection, the number of sensors can be greatly reduced.
[0021] The positioning component is a contour block 4 that matches the product to be tested. The distal end of the contour block 4 has a built-in magnetic component 41 for adsorbing the product. Since the product is a metal part, the magnetic component 41 allows for rapid adsorption and positioning of the product. The contour block 4...
[0022] It has a quick-change, detachable connection with the linear drive mechanism, and different contour parts 4 can be replaced depending on the product to be tested. It should be noted that in this invention, when the product contacts the contour part 4, other parts of the product must also contact the contact plate 3 to compress the spring.
[0023] The contouring component 4 is connected to the base 51 via a quick-change connector, and the base 51 is fixed to the distal end of the slide table 2. The quick-change of the contouring component 4 can be achieved by pressing button 5. The connector can be of various types, such as a spring-loaded snap-fit type. When button 5 is pressed, the snap-fit on the base 51 opens, allowing the contouring component 4 to be removed and the replacement contouring component to be inserted. Releasing button 5 locks the snap-fit onto the contouring component 4. Considering that the specific structure of the quick-change mechanism can be implemented using conventional forms currently available in the mechanical field, it will not be described in detail here.
[0024] Combination Figure 2 and Figure 3As shown, this utility model also discloses an apparatus using the aforementioned floating positioning and detection mechanism. The apparatus includes a conveyor line 7 placed on a frame and a floating positioning and detection mechanism located at the tail end of the conveyor line 7. The sliding cylinder 1 of the floating positioning and detection mechanism operates, driving the positioning component and the detection component to reciprocate towards the product 6. A power mechanism is provided at one end of the conveyor line 7 to drive its operation.
[0025] In this embodiment, product 6 is a caliper housing for automobiles. The caliper housing has three positioning points 61 for gripping by a robotic arm. Typically, positioning points 61 are at the mounting hole locations, and gripping through these locations will not affect the surface of the product. The product can also have other structural forms.
[0026] As product 6 is conveyed to the tail end by the chain conveyor, the slide cylinder 1 operates, causing the positioning and detection components on the slide 2 to extend. As the product is conveyed towards the floating positioning and detection mechanism, the contouring component 4 contacts product 6 and is tightly attracted by the internal magnetic component 41. At this time, the contact plate 3 of the detection component on the other side is pushed by the attraction of product 6, compressing the spring and triggering the proximity sensor. This confirms the product's arrival. The robotic arm (not shown in the figure) grips the product at the positioning point 61. Because the product is tightly attracted by the magnetic component 41, it maintains a stable state during the gripping process and does not slip. Therefore, the robotic arm can accurately grip the product.
[0027] The floating positioning and detection mechanism of this invention can also be applied to other devices that require positioning and grasping.
