Description

Technical Field

[0001] This utility model relates to the field of testing devices, and in particular to a testing device for a voice coil motor. Background Technology

[0002] A voice coil motor is a device that converts electrical energy into mechanical energy and achieves linear and limited swing angle motion. It is widely used in mobile phone camera drivers. During the production process of voice coil motors, it is necessary to detect the positive and negative terminals of the voice coil motor to determine its power supply status. Current testing equipment cannot effectively detect and judge the internal current and resistance of the voice coil motor, and the test results are not intuitive and cannot effectively meet the testing needs of the production line.

[0003] To address the aforementioned issues, existing patent publication number CN207882412U, entitled "A Positive and Negative Polarity Detection Device for Mobile Phone Voice Coil Motor Production," proposes a device that, through the cooperation of an energizing mechanism and a power supply mechanism, can perform energizing detection on each voice coil motor passing through. When the internal circuitry and resistance value of the voice coil motor meet the standards, the metal pointer will rotate to the metal plate, causing the "good product" indicator to light up. This allows operators to intuitively understand the status of the voice coil motor and comprehensively detect its current and resistance. When a defective product is detected, the power supply to the material handling mechanism can be turned on, energizing the electromagnet to attract the voice coil motor, achieving rapid material handling and improving detection efficiency. Furthermore, the turntable ensures that the voice coil motors are evenly distributed on the electromagnet, preventing accumulation.

[0004] However, the aforementioned patents describe a complex process for testing voice coil motors, involving the installation and disassembly of the motors, which takes considerable time and reduces testing efficiency. Therefore, it is necessary to propose a voice coil motor testing device to address this issue. Utility Model Content

[0006] To achieve the above objectives, the present invention provides the following technical solution: a detection device for a voice coil motor, comprising two symmetrically arranged side plates, a conveyor belt rotatably arranged between the two side plates, two bases fixedly arranged on the conveyor belt, a placement groove for placing the motor body fixedly arranged on the surface of the base, a detection component arranged between the middle of the two side plates, and an installation component and a pop-out component arranged on the base.

[0007] The mounting assembly includes a rectangular groove fixedly installed inside the base. Circular grooves, fixed inside the base structure layer, are connected to the top two sides of the rectangular groove. A lifting rod and a base plate are slidably installed inside the circular and rectangular grooves, respectively. The lifting rod and the base plate are fixedly connected. A spring, fitted around the outer ring of the lifting rod, is fixedly connected between the end of the base plate and the end of the circular groove. A connecting rod is fixedly installed at the end of the lifting rod extending beyond the upper surface of the base. A handle is fixedly installed at the top of the connecting rod. A second guide plate is fixedly installed on the side of the lifting rod. The positive and negative ends of the motor body are both connected to the first guide plate via a first wire. In the initial state, the first guide plate is stuck between the base and the second guide plate, and the base plate is attached to the bottom of the rectangular groove. At this time, the spring is in a compressed state.

[0008] Preferably, the pop-out component includes a connecting seat, which is fixedly disposed at the bottom end of the placement groove, and a push rod is slidably disposed inside the connecting seat, with the lower end of the push rod extending movably into the interior of the rectangular groove.

[0009] Preferably, one side of the rectangular groove is connected to a sliding groove fixed inside the base structure layer, the end of the base plate extends movably into the interior of the sliding groove, and a prompting rod fixed to the side of the base is provided in the middle of the outer side of the sliding groove.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides, for example Figures 1-4 The illustrated voice coil motor testing device includes two symmetrically arranged side plates 1, with a conveyor belt 4 rotatably mounted between the two side plates 1. Two bases 5 are fixedly mounted on the conveyor belt 4, and a placement groove for placing a motor body 6 is fixedly provided on the surface of each base 5. A testing component is arranged between the middle of the two side plates 1. When using this voice coil motor testing device, by setting the two bases 5 such that one base 5 is located below the testing component, the positive and negative terminals of the motor body 6 on that base 5 are detected to determine its energization status. At the same time, the motor body 6 on the base 5 located outside the testing component is installed, awaiting the next test. In this way, the detection gap between the two motor bodies 6 is greatly shortened, thereby improving the testing efficiency of this voice coil motor testing device.

[0026] In addition, the present invention provides an installation component and a pop-out component on the base 5. By installing the installation component, it is easy to quickly fix the motor body 6 on the base 5. By installing the pop-out component, it is easy to quickly remove the motor body 6 from the base 5, thereby simplifying the installation and removal steps of the motor body 6.

[0027] Furthermore, the mounting components include a rectangular groove 8 fixedly disposed inside the base 5, and circular grooves 9 fixed inside the structural layer of the base 5 connected to the top two sides of the rectangular groove 8. A lifting rod 11 and a base plate 10 are slidably disposed inside the circular groove 9 and the rectangular groove 8, respectively. The lifting rod 11 and the base plate 10 are fixedly connected. A spring 13 fitted around the outer ring of the lifting rod 11 is fixedly connected between the end of the base plate 10 and the end of the circular groove 9. A connecting rod 14 is fixedly disposed at one end of the lifting rod 11 that extends out of the upper surface of the base 5. A handle 15 is fixedly disposed at the top of the connecting rod 14. A second guide plate 12 is fixedly disposed on the side of the lifting rod 11. The positive and negative ends of the motor body 6 are both connected to the first guide plate 7 through the first wire. In the initial state, the first guide plate 7 is stuck between the base 5 and the second guide plate 12, and the base plate 10 is attached to the bottom of the rectangular groove 8. At this time, the spring 13 is in a compressed state.

[0028] Furthermore, the pop-out component includes a connecting seat 16, which is fixedly disposed at the bottom end of the placement groove. A push rod 17 is slidably disposed inside the connecting seat 16, and the lower end of the push rod 17 extends movably into the interior of the rectangular groove 8.

[0029] When installing the motor body 6, pull the handle 15 up halfway, which will lift the lifting rod 11 and the second guide plate 12. After placing the first guide plate 7 under the second guide plate 12, release the handle 15. The spring 13 will then return to its elasticity, which will push the base plate 10 and the lifting rod 11 downwards, allowing the second guide plate 12 to press the first guide plate 7 firmly onto the base 5. This completes the installation of the motor body 6. The operation is simple and convenient.

[0030] When disassembling and inspecting the motor body 6, pull the handle 15 up to the full distance, so that the second guide plate 12 releases the first guide plate 7, and the base plate 10 lifts the top rod 17, thereby tilting the motor body 6 in the placement slot, so that it can automatically slide out of the placement slot, thereby unloading the motor body 6.

[0031] In summary, this utility model allows for the installation and disassembly of the motor body 6 simply by pulling up the handle 15. This solves the problem that existing voice coil motor testing devices require a lot of time and are complex to install and disassemble when testing the motor body 6, thus reducing the testing efficiency of the motor body 6.

[0032] In order to better control the lifting distance of the handle 15, a slide groove 18 fixed inside the structural layer of the base 5 is provided on one side of the rectangular groove 8. The end of the base plate 10 extends into the interior of the slide groove 18. A prompting rod 19 fixed to the side of the base 5 is provided in the middle of the outer side of the slide groove 18. The height of the prompting rod 19 is the same as the height of the bottom of the top rod 17, and the outside of the prompting rod 19 is dyed yellow.

[0033] When installing the motor body 6, simply pull the base plate 10 to the position of the indicator rod 19 so that the base plate 10 does not contact the top rod 17. When disassembling the motor body 6, pull the base plate 10 to the top of the slide groove 18 so that the base plate 10 pushes the top rod 17 out completely, thereby sliding the motor body 6 out of the placement groove and improving the practicality of the device.

[0034] Furthermore, the detection assembly includes a detector 23 located above the center of the conveyor belt 4. A column 22 is fixedly installed at each of the four corners of the bottom of the detector 23. The column 22 is fixedly connected to the side plate 1. Two symmetrically arranged electric push rods 24 are installed at the bottom of the detector 23. A third guide plate 25 is installed at the telescopic end of the electric push rod 24. The positive and negative ends of the detector 23 are connected to the two third guide plates 25 respectively via a second wire. When the base 5 is located directly below the detector 23, the third guide plate 25 and the second guide plate 12 correspond to each other in the vertical direction. An indicator light 26 is installed on the top of the detector 23.

[0035] When the base 5 is moved to the position directly below the detector 23 by the conveyor belt 4, the electric push rod 24 is activated to make the third guide plate 25 and the second guide plate 12 fit together, thereby detecting the positive and negative poles of the motor body 6 to determine its power supply status. If it is qualified, the indicator light 26 will show green; if it is unqualified, the indicator light 26 will show red.

[0036] To quickly collect qualified and unqualified products, a first collection box 20 and a second collection box 21 are installed on the side plate 1 at the rear end. There are two first collection boxes 20. The second collection box 21 is located behind the detection component. When an unqualified product is encountered, the handle 15 is pulled up to let the unqualified product slide into the second collection box 21. When a qualified product is encountered, the conveyor belt 4 moves the base 5 to the position of the first collection box 20, and the handle 15 is pulled up again to let the qualified product slide into the first collection box 20. This allows for the rapid collection of qualified and unqualified products and improves the practicality of the device.

[0037] Furthermore, a controller 3 is installed on the front side plate 1, and support rods 2 are installed at the bottom of both side plates 1. The rotation state of the conveyor belt 4 is adjusted by installing the controller 3.
