Description

Technical Field

[0001] This utility model relates to the field of testing technology, specifically a testing device for surface mount capacitor production. Background Technology

[0002] Surface mount capacitors, as a fundamental and crucial electronic component, are widely used in various electronic products, such as mobile phones, computers, and automotive electronics. With the trend towards miniaturization and high performance in electronic products, higher demands are being placed on the quality and production efficiency of surface mount capacitors. Therefore, efficient and accurate testing is essential in the production process of surface mount capacitors. It not only ensures product quality but also improves production efficiency and reduces production costs.

[0003] Existing surface mount capacitor testing devices typically use conveyor belts to transport surface mount capacitors to the testing area, where high-precision testing equipment measures various parameters of the capacitors. In the sorting and collection phase after testing, simple robotic arms or pushers are used to push the capacitors into different collection containers.

[0004] When using robotic arms or push rods for sorting, the continuous movement of surface-mount capacitors on the conveyor belt, coupled with the relatively slow movement of the robotic arms or push rods, leads to low sorting efficiency. During large-scale production, a large number of surface-mount capacitors accumulate on the conveyor belt, severely impacting production schedules. Utility Model Content

A rotating groove is formed on the side wall of the intermediate plate near the transport mechanism, and a rotating shaft is arranged in the rotating groove. The partition plate rotatably engages with the rotating shaft. The first motor is located on the top of the intermediate plate, and its output end is connected to the rotating shaft. The testing mechanism is used to test the surface mount capacitors, and a controller is located on the side wall of the workbench.

[0022] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] like Figures 1 to 3 As shown, a testing device for surface mount capacitor production includes a workbench 1, a transport mechanism, and a testing mechanism. The transport mechanism is located on the top of the workbench 1, and surface mount capacitors are placed on the transport mechanism. A collection box 2 is located on the side wall of the workbench 1, and a material distribution mechanism is located on the top of the collection box 2. The material distribution mechanism includes an intermediate plate 3, a partition plate 34, and a first motor 33. The intermediate plate 3 is located at the top center of the collection box 2, and one end of the intermediate plate 3 extends above the transport mechanism. A rotating groove 31 is formed on the side wall of the intermediate plate 3 near the transport mechanism, and a rotating shaft 32 is arranged in the rotating groove 31. The partition plate 34 is rotatably engaged with the rotating shaft 32. The first motor 33 is located on the top of the intermediate plate 3, and its output end is connected to the rotating shaft 32. The testing mechanism is used to test the surface mount capacitors, and a controller 7 is located on the side wall of the workbench 1.

[0024] Through the coordinated operation of controller 7 and the sorting mechanism, the chip capacitors can be accurately classified and collected according to the test results, ensuring effective control of product quality. This facilitates the subsequent packaging and shipping of qualified products and the rework or scrapping of unqualified products.

[0025] The transport mechanism includes a conveyor belt 41 and a second motor 4. A transport trough is provided on the workbench 1. The conveyor belt 41 is rotatably disposed in the transport trough. The second motor 4 drives the conveyor belt 41 to rotate.

[0026] When the second motor 4 is powered on, its output shaft drives the transmission wheel of the conveyor belt 41 to rotate, causing the conveyor belt 41 to rotate cyclically in the transport trough. This drives the chip capacitors placed on the conveyor belt 41 to move forward, providing stable power to drive the transport of the chip capacitors, ensuring the continuity of the testing process and improving testing efficiency.

[0027] The testing mechanism includes a testing frame 5 and a camera 51. The testing frame 5 is fixedly mounted on the workbench 1, and the camera 51 is fixedly mounted on the side wall of the testing frame 5, and the camera 51 is located above the conveyor belt 41.

[0028] As the surface-mount capacitor moves along conveyor belt 41 to below camera 51, camera 51 captures an image of the capacitor and transmits the image data to controller 7. Controller 7 processes and analyzes the image using machine vision algorithms, compares it with a standard image, and determines whether the surface-mount capacitor is qualified.

[0029] Non-contact inspection methods do not cause physical damage to surface-mount capacitors, have a fast inspection speed, can meet the rapid inspection needs of high-speed production lines, and can acquire rich image information to achieve multi-dimensional inspection.

[0030] The workbench 1 is equipped with limiting plates 6, which are located on both sides of the conveyor belt 41. The limiting plates 6 act as blocks for the surface mount capacitors on both sides of the conveyor belt 41, preventing them from deviating from the track during transportation due to vibration, conveyor belt 41 shaking, or other external forces; ensuring stable transportation of the surface mount capacitors on the conveyor belt 41, avoiding detection errors or incorrect material distribution due to positional deviation, and improving the accuracy of detection and material distribution.

[0031] The collection box 2 is provided with two collection slots 21, which are located on both sides of the middle plate 3, and inclined plates 22 are provided in the collection slots 21.

[0032] After being processed by the inspection and sorting mechanism, qualified and unqualified surface mount capacitors fall into the collection slots 21 on both sides of the intermediate plate 3. The inclined plate 22 allows the surface mount capacitors that fall into the collection slots 21 to slide down and accumulate along the inclined plate 22, which facilitates centralized storage and subsequent sorting.

[0033] One end of the limiting plate 6 extends to the collection groove 21. It continues to serve as a guide, ensuring that the surface-mount capacitors fall accurately into the corresponding collection groove 21 and preventing them from falling out of the collection box 2.

[0034] The separator 34 has a first arc surface 35 on the end away from the collection box 2. When the separator 34 rotates, the first arc surface 35 contacts the surface-mount capacitor, allowing the surface-mount capacitor to be guided more smoothly to the corresponding collection slot 21, reducing hard collisions between the separator 34 and the surface-mount capacitor.

[0035] The intermediate plate 3 has a second arc surface 36 at one end near the conveyor belt 41. When the chip capacitor is conveyed to the position of the intermediate plate 3, the second arc surface 36 guides it to transition smoothly, avoiding positional displacement or jamming of the chip capacitor due to a right-angle transition.

[0036] The workbench 1 has several support legs 11 at its bottom. The support legs 11 support the workbench 1, keeping the entire testing device at a certain distance from the ground, providing space under the equipment for wiring, cleaning and other operations, while ensuring the stability of the workbench 1.

[0037] The controller 7 is equipped with a display screen 71 and control buttons 72. The display screen 71 displays detection data, equipment operating status and other information in real time. The operator can start, stop and set parameters of the equipment through the control buttons 72 to realize manual intervention and control of the detection device.

[0038] The working principle of this utility model is as follows: At the start of operation, the second motor 4 is energized, and its output shaft drives the transmission wheel of the conveyor belt 41 to rotate, causing the conveyor belt 41 to circulate within the transport trough. The surface-mount capacitors placed on the conveyor belt 41 move forward accordingly. When the surface-mount capacitors move below the camera 51, the camera 51 captures an image, which is then transmitted to the controller 7. The controller 7 analyzes the image using a preset machine vision algorithm, comparing it with a standard image template to determine if the surface-mount capacitors have any appearance defects, dimensional deviations, or polarity errors. After the inspection is completed, the surface-mount capacitors continue to move with the conveyor belt 41 to the sorting mechanism. At this time, the controller 7 controls the first motor 33 to operate based on the inspection results. The output shaft of the first motor 33 drives the rotating shaft 32 to rotate, which in turn drives the separator plate 34 to rotate to the corresponding position within the rotating trough 31, guiding the qualified and unqualified surface-mount capacitors into the collection troughs 21 on both sides of the intermediate plate 3. The inclined plates 22 within the collection troughs 21 facilitate the sliding and accumulation of the surface-mount capacitors, making subsequent sorting easier.

[0039] The above embodiments are only used to illustrate the technical methods of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of this utility model without departing from the spirit and scope of the technical methods of this utility model.
