Technical Field

[0001] The utility model relates to the technical field of detection devices, in particular to a detection device with a positioning structure. Background Art

[0002] A detection device with a positioning structure refers to a device that can determine the position of the object being tested during the detection process. This device is usually used in industrial automation, quality control, robotics and other fields to ensure the accuracy and precision of the object being tested during the detection process. After the back cover of a mobile phone is produced and coated, a series of tests such as its flatness are also required.

[0003] When inspecting the back cover of a mobile phone, the existing inspection devices mostly need to fix the coated back cover of the mobile phone by a clamp. The back cover of the mobile phone is mostly made of composite materials and has a coating on the surface. When clamped by the clamp, it is not easy to control the clamping force of the back cover of the mobile phone. If the clamping force is too large, the back cover of the mobile phone will be deformed or even damaged. Otherwise, it will be not firmly fixed and easy to fall off during inspection.

When the flatness of the back cover of the mobile phone after coating is tested, the back cover of the mobile phone after production is placed on the detection table 21, and then the cylinder 220 is started, and the output shaft of the cylinder 220 will push the linkage plate 24 to slide, and the linkage plate A transverse groove 25 is provided on the surface of 24, and a slider 1 26 is passed through the inner side of the transverse groove 25. A connecting plate 27 is fixedly connected to the surface of the slider 1 26. A sliding groove 210 is provided on the surface of the connecting plate 27. A slider 29 is passed through and slidably connected to the inner side of the sliding groove 210. When the linkage plate 24 is pushed, the connecting plate 27 will be driven to move together through the slider 1 26, and when the connecting plate 27 moves, it will drive the positioning plate 28 to move together through the slider 2 29. The surface of the slider 29 is fixedly connected to the positioning plate 28. The inner wall of the transverse groove 25 is fixedly connected with a spring 1 218, and the slide bar 215 slides along the limit rail 22 and the guide groove 219, and the slide bar 215 slides along the inclined part of the limit rail 22, thereby driving the connecting plate 27 to make the slider 1 26 slide along the transverse groove 25, so that the spring 1 218 is compressed, and the positioning plate 28 is also driven to fit with the back cover of the mobile phone. The end of the spring 1 218 away from the inner side of the transverse groove 25 is fixedly connected to the surface of the slider 1 26. The inner side of the transverse groove 25 is fixedly connected with a spring 211, and the end of the spring 211 away from the inner side of the transverse groove 25 is fixedly connected to the surface of the slider 29. The side of the positioning plate 28 close to the connecting plate 27 is fixedly connected with the hinge block 212, and the bottom surface of the hinge block 212 is penetrated and hinged with the hinge rod 213. When the positioning plate 28 is attached to the back cover of the mobile phone, the cylinder 220 has not stopped, resulting in the distance between the positioning plate 28 and the connecting plate 27 being shortened, and the positioning plate 28 will shorten the distance between the hinge block 212 and the connecting plate 27, causing the hinge rod 213 and the hinge block 212 to rotate to a certain extent. The surface of the connecting plate 27 is slidably connected with a push rod 214, and the hinge rod 213 and the hinge block 212 are hinged to a certain extent. The hinge block 212 will push the push rod 214 to slide downward, and the push rod 214 will push the sliding ring 216 to move downward, and the sliding ring 216 will drive the latching tooth 217 to move downward and be stuck in the limit tooth 23, and the top surface of the push rod 214 is penetrated and hinged by the hinge rod 213. The bottom surface of the connecting plate 27 is fixedly connected with a slide bar 215, and the sliding ring 216 drives the latching tooth 217 to move downward and engage in the limiting tooth 23, so that the slide bar 215 stops sliding, and then the positioning plate 28 stops clamping the back cover of the mobile phone.

Finally, the laser detector 4 is used to perform a series of tests on the flatness of the back cover of the mobile phone.

[0027] At the same time, when the L-shaped positioning plate 28 positions the back cover of the mobile phone, the L-shaped part of the positioning plate 28 will hook the back cover of the mobile phone to clamp it, but the positioning plate 28 will have a certain elasticity due to the slider 29 and the spring 211, so as to prevent the inner side of the positioning plate 28 from clamping the back cover of the mobile phone too tightly and causing damage, so that the control unit 2 can detect the back covers of mobile phones of various sizes.
