Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, and in particular to a magnet polarity testing device for 3C products. Background Technology

[0002] 3C products typically refer to small household appliances such as computers, tablets, mobile phones, and digital cameras. These electronic products often have many control boards and mounting boards during the manufacturing process, and magnets are often placed on some of these boards.

[0003] Since circuit boards are usually made of metal, magnets can be assembled onto them using magnetic attraction. However, this can easily lead to situations where multiple magnets have different polarities after assembly. This can result in defective products during the assembly process of electronic products, increasing the defect rate. Therefore, after the magnets are assembled, it is necessary to test the polarity of the magnets on the circuit board to ensure the accuracy of the polarity of the magnets located on the circuit board.

[0004] The current testing method involves placing 3C products on a conveyor belt for circulation. As the products pass by inspectors, they are manually removed from the conveyor belt for manual testing. In order to improve the efficiency of testing, multiple inspectors are often deployed on a single conveyor belt to simultaneously perform the magnetic polarity test. This testing method is heavily dependent on the number of inspectors and their labor intensity, resulting in low testing efficiency or high labor costs.

[0005] Therefore, a new technical solution is urgently needed to solve the above-mentioned technical problems. Utility Model Content

[0006] The purpose of this invention is to provide a magnet polarity detection device for 3C products to overcome the defects mentioned in the background art.

[0007] A magnet polarity detection device for 3C products includes an operating table, on which:

[0008] A conveying device is provided with a conveying channel for the 3C products to flow in a predetermined direction. A width adjustment mechanism is provided at the inflow end of the conveying channel to adjust the width of the inlet end of the conveying channel. The width adjustment mechanism includes two mechanisms located on both sides of the conveying channel. Each width adjustment mechanism includes a limiting plate, and the limiting plate is movably connected to the conveying device through a swing arm.

[0009] A testing fixture is used to perform polarity detection on the 3C product, and a plurality of magnetic sensors are provided at the polarity positioning positions on the testing fixture.

[0010] The transfer mechanism is used to transport the 3C product conveyed by the conveying device to the testing fixture for testing. The transfer mechanism includes a multi-axis moving module and a suction seat driven by the multi-axis moving module. A plurality of suction nozzles are arranged in a matrix on the suction seat.

[0011] Furthermore, the conveying device includes opposing frames, at least two drive shafts are mounted on the two frames, and a drive motor that is connected to one of the drive shafts is fixedly mounted on the frame. The conveyor belt is mounted on the at least two drive shafts, and the surface of the conveyor belt defines the conveying channel.

[0012] Furthermore, the limiting plate extends along the conveying direction of the conveyor belt;

[0013] One end of the swing arm is detachably mounted on the frame via fasteners, and the other end extends toward the centerline of the conveyor belt and is detachably mounted at the center of the limiting plate via fasteners.

[0014] Furthermore, the swing arms above each of the width adjustment mechanisms are configured as two parallel arms, such that the two swing arms, the limiting plate, and the frame define a parallelogram.

[0015] Furthermore, the conveying device is configured as a first segment and a second segment spaced apart from each other, the width adjustment mechanism is disposed on the first segment, and the detection fixture is disposed between the first segment and the second segment.

[0016] Furthermore, baffles are respectively provided at the ends of the first segment and the second segment along the conveying direction to prevent the 3C products from flowing out of the conveying channel.

[0017] Furthermore, the testing fixture includes:

[0018] A fixture plate, which is used to support the 3C product;

[0019] The positioning components, including multiple components, are arranged in a rectangular pattern on the fixture plate to define a clamping space for placing the 3C product. The magnetic sensor is positioned within the clamping space according to a predetermined location.

[0020] Furthermore, the positioning components include fixed components fixedly mounted on the fixture plate and movable components movably connected to the fixture plate. The fixed components define two adjacent sides of the clamping space, and the movable components define two other adjacent sides of the clamping space. The fixture plate is also equipped with clamping cylinders that are respectively connected to the movable components for driving the movable components to reciprocate towards the corresponding fixed components.

[0021] Furthermore, the multi-axis moving module includes a first linear module arranged along the direction from the conveying device to the testing fixture, and a second linear module mounted on the first linear module and arranged in the vertical direction. The suction seat is mounted on the second linear module and reciprocates in the vertical direction under its drive.

[0022] Furthermore, a rotary cylinder is also installed on the second linear module, and the suction seat is fixedly installed on the output shaft of the rotary cylinder and driven to rotate by the rotary cylinder.

[0023] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0024] This embodiment provides a 3C product magnet polarity detection device. During the detection process, a conveying device transports the 3C product to be tested. Specifically, the 3C product to be tested is placed within the conveying channel of the conveying device, allowing it to flow in a predetermined direction. At a position corresponding to the transfer mechanism, a suction seat moves under the drive of a multi-axis moving module, thereby grabbing the 3C product and transferring it to a detection fixture. Several magnetic sensors on the fixture detect the polarity of the magnet on the 3C product. In this embodiment, the magnetic sensors can be commonly available sensors that determine the magnet polarity by the direction of the magnetic field or the direction of the magnetic field lines. When the polarity direction differs from the preset polarity direction, an alarm is triggered, thereby removing and concentrating the unqualified 3C products. After the 3C products that pass the test are grabbed by the transfer mechanism, they are placed back on the conveying device to proceed to the next processing step. The technical solution provided in this embodiment can complete the automatic detection operation, reducing reliance on manual labor in the detection process, thereby reducing labor input, lowering labor costs in the detection process, and improving detection efficiency. Meanwhile, to meet the testing needs of electronic products of different sizes and models, the conveying process requires precise transport of the electronic products. This means that the conveying process must correspond with the transfer mechanism so that the transfer mechanism can accurately pick up the 3C products to be tested and place them on the testing fixture. Therefore, in order to adapt to the precise transport and testing of products of different sizes, two opposing width adjustment mechanisms are set on the conveying device to adjust the width of the conveying channel, thereby enabling the transport of 3C products of different widths. During the transport process, two limiting plates restrict the two sides of the 3C products, causing them to be transported along the conveying channel defined by the two limiting plates, and thus transported to the position that precisely corresponds to the transfer mechanism, so that the transfer mechanism can accurately pick them up and place them on the testing fixture.

[0030] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining this utility model and are not intended to limit this utility model.

[0031] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0032] Furthermore, the use of terms such as "first" and "second" in the embodiments of this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated.

[0033] This utility model provides a 3C product magnet polarity detection device for detecting the polarity of magnets installed on electronic product accessories. The detection device provided by this technical solution can complete continuous and automated detection work, thereby reducing the dependence on manual labor and reducing the labor intensity of manual labor, thereby improving detection efficiency and reducing detection costs.

[0034] like Figure 1-4As shown in the figure, the 3C product magnet polarity detection device provided by this utility model includes an operating table 100. On the operating table 100 are: a conveying device 200 for conveying the 3C product to be tested in a predetermined direction; a detection fixture 300 for positioning and clamping the 3C product to be tested; and a transfer mechanism 400 for transferring the 3C product to be tested between the conveying device 200 and the detection fixture 300. The conveying device 200 is provided with a conveying channel 201 for the 3C product to flow in a predetermined direction. A width adjustment mechanism 220 is provided at the inflow end of the conveying channel 201 to adjust the width of the inlet end of the conveying channel 201. The width adjustment mechanism 220 includes two located on both sides of the conveying channel 201. Each width adjustment mechanism includes a limiting plate 221, which is movably connected to the conveying device 200 via a swing arm 222. The detection fixture 300 is used to perform polarity detection on the 3C product, and a plurality of magnetic sensors 301 are provided at the polarity positioning position on the detection fixture 300. The transfer mechanism 400 is used to transport the 3C product conveyed by the conveying device 200 to the detection fixture 300 for detection. The transfer mechanism 400 includes a multi-axis moving module 410 and a suction seat 420 driven by the multi-axis moving module 410. A plurality of suction nozzles 421 arranged in a matrix are provided on the suction seat 420.

[0035] During the testing process, the conveying device 200 transports the 3C product to be tested. Specifically, the 3C product is placed within the conveying channel 201 of the conveying device 200, allowing it to flow in a predetermined direction within the channel 201. At a position corresponding to the transfer mechanism 400, the suction seat 420 moves under the drive of the multi-axis moving module 410, thereby gripping the 3C product and transferring it onto the testing fixture 300. Several magnetic sensors 301 on the fixture detect the polarity of the magnets located on the 3C product. In this embodiment, the magnetic sensors... Sensor 301 can be a common sensor 301 on the market. It determines the polarity of the magnet by the direction of the magnetic field or the direction of the magnetic field lines, and triggers an alarm when the polarity direction is different from the preset polarity direction. This allows unqualified 3C products to be removed and placed in a centralized location. After the 3C products that pass the test are picked up by the transfer mechanism 400, they are placed back on the conveyor device 200 to flow to the next processing step. The technical solution provided in this embodiment can complete the automatic detection operation, reduce the dependence on manual labor in the detection process, thereby reducing the input of manual labor, reducing the labor cost in the detection process, and improving the detection efficiency. Meanwhile, to meet the testing needs of electronic products of different sizes and models, the electronic products need to be transported precisely during the conveying process. This means that the products must correspond to the transfer mechanism 400 during the conveying process, so that the transfer mechanism 400 can accurately pick up the 3C products to be tested and place them on the testing fixture 300. Therefore, in order to adapt to the precise conveying and testing of products of different sizes, two opposing width adjustment mechanisms 220 are provided on the conveying device 200, so as to adjust the width of the conveying channel 201 and thus convey 3C products of different widths. During the conveying process, two limiting plates restrict the two sides of the 3C products, so that they are conveyed along the conveying channel 201 defined by the two limiting plates, and thus conveyed to the position that corresponds precisely to the transfer mechanism 400, so that the transfer mechanism 400 can accurately pick them up and place them on the testing fixture 300.

[0036] like Figure 2As shown, the conveying device 200 includes opposing frames 210, with at least two drive shafts mounted on the frames 210. A drive motor 212, connected to one of the drive shafts, is also fixedly mounted on each frame 210. A conveyor belt 213 is fitted onto the at least two drive shafts, and the surface of the conveyor belt 213 defines a conveying channel 201. In this embodiment, two width adjustment mechanisms are respectively mounted on the frames 210, with limiting plates located inside the conveyor belt 213. This allows for adjustment of the conveying channel 201 defined by the surface of the conveyor belt 213 by adjusting the gap between the two limiting plates, thereby enabling precise conveying of 3C products.

[0037] In this embodiment, the limiting plate 221 extends along the conveying direction of the conveyor belt 213, thereby enabling continuous positioning of the 3C products during the flow process, thus ensuring accurate conveying. Meanwhile, one end of the swing arm 222 is detachably mounted on the frame 210 by fasteners, and the other end extends toward the centerline of the conveyor belt 213 and is detachably mounted at the middle position of the limiting plate 221 by fasteners. In this embodiment, the fastener can be a bolt. After loosening the bolt, the connection between the swing arm 222 and the frame 210 can be loosened, allowing the swing arm 222 to swing along the bolt. This allows the limiting plate to move toward or away from the center line of the conveyor belt 213, thereby adjusting the gap width between the two limiting plates. At the same time, by loosening the bolt between the swing arm 222 and the limiting plate, the limiting plate can swing along the bolt, thereby adjusting the axial direction of the limiting plate so that the axial direction of the limiting plate is parallel to the axial direction of the conveyor belt 213, ensuring the accuracy of the conveying.

[0038] To ensure accuracy during the adjustment of the limiting plates, keeping them parallel and ensuring their axes are parallel to the centerline of the conveyor belt 213, the swing arms 222 on each width adjustment mechanism 220 are configured as two parallel arms. This, along with the limiting plates 221 and the frame 210, defines a parallelogram, equivalent to a non-power-transmitting planar linkage mechanism. By defining the two swing arms 222, the limiting plates, and the frame 210 as a parallelogram, even after loosening all bolts, the shape of the parallelogram changes. However, the limiting plates and the frame 210 remain parallel, meaning the two limiting plates are always parallel to the centerline of the conveyor belt 213, thus maintaining accuracy during the width adjustment of the conveyor channel 201.

[0039] In this embodiment, as Figure 1-2As shown, the conveying device 200 is configured with a first section 214 and a second section 216 spaced apart from each other. The width adjustment mechanism is located on the first section 214, and the inspection fixture 300 is located between the first section 214 and the second section 216. By configuring the conveying device 200 into two spaced-apart parts, it can be divided into a first section 214 for loading and a second section 216 for unloading. This allows the loading and unloading to be performed independently, without interfering with each other, ensuring the continuity of the entire process. It is worth noting that the first section 214 and the second section 216 have the same structure, that is, both include a frame 210 facing each other, at least two drive shafts rotatably mounted on the frame 210, a conveyor belt 213 mounted on the drive shafts, and a drive motor 212 connected to one of the drive shafts.

[0040] In this embodiment, to prevent 3C products from falling off the first section 214 and the second section 216 during the conveying process, baffles 217 are respectively provided at the ends of the first section 214 and the second section 216 along the conveying direction to prevent the 3C products from flowing out of the conveying channel 201. By setting the baffles 217, the 3C products can be effectively blocked on the conveyor belt 213, preventing them from falling off.

[0041] In this embodiment, the detection fixture 300 includes a fixture plate 310 and positioning members 320. The fixture plate 310 is used to support the 3C product. Multiple positioning members 320 are arranged in a rectangular pattern on the fixture plate 310, defining a clamping space 321 for placing the 3C product. A magnetic sensor 301 is positioned within the clamping space 321. After the transfer mechanism 400 picks up the 3C product within the conveying channel 201, it places it within the clamping space 321 on the fixture plate 310, allowing the magnetic sensor 301 to detect the 3C product.

[0042] Similarly, to accommodate 3C products of different sizes to be tested, several positioning components 320 include fixed components 323 fixedly mounted on the fixture plate 310 and movable components 322 movably connected to the fixture plate 310. The fixed components 323 define two adjacent sides of the clamping space 321, and the movable components 322 define another two adjacent sides of the clamping space 321. The fixture plate 310 is also equipped with clamping cylinders 324, which are respectively pulsatorically connected to the movable components 322, to drive the movable components 322 to reciprocate towards the corresponding fixed components 323. By driving the movable components 322 to move through the clamping cylinders 324, the size and shape of the clamping space 321 can be adjusted to accommodate 3C products of different sizes.

[0043] In this embodiment, as Figure 4As shown in the illustration, this embodiment provides a specific example of a multi-axis moving module 410. The multi-axis moving module 410 includes a first linear module 411 arranged along the direction from the conveying device 200 to the detection fixture 300, and a second linear module 412 mounted on the first linear module 411 and arranged vertically. A suction seat 420 is mounted on the second linear module 412 and reciprocates vertically under its drive. Movement along two axes is achieved through the first linear module 411 and the second linear module 412, thereby completing the transfer and material handling operations. Simultaneously, to improve the accuracy of loading 3C products into the clamping space 321, a rotary cylinder 413 is also mounted on the second linear module 412. The suction seat 420 is fixedly mounted on the output shaft of the rotary cylinder 413 and is driven to rotate by the rotary cylinder 413. In other words, during the placement of 3C products, the 3C products can be rotated by the rotary cylinder 413 to change their orientation, thereby improving the accuracy of placing the 3C products.

[0044] For those skilled in the art, various other corresponding changes and modifications can be obtained based on the structure and principles disclosed in this utility model, and all such changes and modifications fall within the protection scope of this utility model.
