Description

Technical Field

[0001] This utility model relates to the field of testing, and in particular to a device for detecting appearance defects in ceramic capacitors. Background Technology

[0002] With the rapid development of electronic technology, the performance and reliability requirements of electronic devices are becoming increasingly stringent. Ceramic capacitors, as one of the key components in electronic devices, directly affect the performance and stability of the entire device. Ceramic capacitors with appearance defects may experience performance degradation, short circuits, or failures during use, thus affecting the safety and lifespan of electronic devices, and potentially even causing serious safety accidents and economic losses. Therefore, to ensure product quality and safety, rigorous inspection of ceramic capacitor appearance defects is essential.

[0003] Traditionally, the visual inspection of ceramic capacitors relies primarily on manual inspection. This method is not only time-consuming and labor-intensive, but also slow, failing to meet the efficiency requirements of modern large-scale production. Furthermore, it is prone to misjudgments and omissions; for example, small cracks, scratches, and color differences are easily overlooked, thus affecting the product pass rate. Inconsistent inspection standards and results among different inspectors also lead to a lack of objectivity and stability. Currently, there is a strong push to develop equipment-based inspection methods to improve efficiency and accuracy. Therefore, this application presents an automatic ceramic capacitor visual defect inspection device. Utility Model Content

[0027] Reference Figure 3 The loading platform 11 includes two fixed side plates 111 and a drawer-type slide 112 disposed between the fixed side plates 111. The tray 201 carrying the product 200 to be inspected is placed on the drawer-type slide 112. The drawer-type slide 112 can be pulled out and pushed in from between the fixed side plates 111, similar to the sliding principle of a drawer. The loading positioning mechanism 13 is mounted above the drawer-type slide 112 to capture and position the tray 201 and the product 200 on it, and feeds back the position information to the loading robot 12 for accurate material handling.

[0028] Reference Figure 4 The transfer mobile platform 21 includes a guide rail 211, a platform support 212, and a cylinder 213. The guide rail 211 and the cylinder 213 are mounted on the machine base 100. The platform support 212 is movably mounted on the guide rail 211 via a slider 214. The slider 214 is connected to the piston end of the cylinder 213. If a pen-shaped cylinder is used in this embodiment, the slider 214 is connected to the piston rod of the pen-shaped cylinder, and is driven by the cylinder 213 to reciprocate along the guide rail 211. Two platform supports 212 are movably mounted on the guide rail 211. A cylinder 213 is located at each end of the guide rail 211, driving the two platform supports 212 respectively. Each platform support 212 has multiple product slots 2121, which are arranged in a row at equal intervals or in a matrix pattern. The transfer mobile platform 21 serves as a receiving and buffering mechanism, improving the continuous operation efficiency of the device.

[0029] Reference Figure 5Two handling robots 22 are provided, respectively located at both ends of the transfer platform 21. Each handling robot 22 includes an X-axis linear module 221, a Y-axis linear module 222, a lifting module 223, and a first suction nozzle 224. The X-axis linear module 221 is mounted on one end of the transfer platform 21, and the Y-axis linear module 222 is mounted on the X-axis linear module 221. The X-axis linear module 221 drives the robot to perform reciprocating linear motion between the transfer platform 21 and the conveying module 41.

Multiple first suction nozzles 224 are arranged in a straight line on the lifting module 223 and driven by the lifting module 223 to perform lifting movements. The number of first suction nozzles 224 preferably corresponds to the product slots 2121 on the platform support 212, so as to efficiently transfer the products to be inspected on the platform support 212 in one go. The design of the X-axis linear module 221, Y-axis linear module 222, and lifting module 223 can adapt to the transfer of products of various sizes and specifications, and existing linear motor modules, lead screw linear modules, etc. can be used as needed.

[0030] Reference Figure 6 The product carrier 42 mounted on the conveying and moving module 41 includes a moving plate 421, a carrier frame 422, multiple second suction nozzles 423, and multiple motors 424. The moving plate 421 is mounted on the conveying and moving module 41 and is driven by the conveying and moving module 41 to move linearly. The conveying and moving module 41 can be a linear module such as a linear motor module or a linear screw module. In this embodiment, a linear motor module is selected. The carrier frame 422 is mounted on the movable plate 421. The second suction nozzles 423 and the motor 424 are mounted on the carrier frame 422. Multiple second suction nozzles 423 are arranged in a straight line at equal intervals on the carrier frame 422. The spacing and number of the multiple second suction nozzles 423 are the same as the arrangement of the first suction nozzles 224 on the handling robot 22. Each motor 424 corresponds one-to-one with a second suction nozzle 423; that is, one second suction nozzle 423 is paired with one motor 424. The second suction nozzles 423 are movably mounted on the carrier frame 422 via a rotating shaft 425. The rotating shaft 425 is connected to the output end of the motor 424 via a belt 426. Specifically, a synchronous pulley 427 is fitted around the outer ring of the rotating shaft 425, and a synchronous pulley 427 is also provided at the output end of the motor 424. The two synchronous pulleys 427 are connected by a belt 426. Thus, the rotation of the motor 424 drives the rotating shaft 425 to rotate, and the rotating shaft 425 drives the second suction nozzle 423 to rotate, realizing the rotation and side-changing of the product fixed on the second suction nozzle 423. One motor 424 drives one second suction nozzle 423, which can realize the adjustment of individual products and has greater flexibility.

[0031] The material sorting platform includes a qualified product unloading platform 52 and an unqualified product unloading platform 53. Both platforms have the same structure as the loading platform 11, featuring a drawer-type design for easy unloading of entire trays of products and loading of empty trays. Qualified products are those without any visible defects on all surfaces, while unqualified products are the opposite. The marked positions of the qualified product unloading platform 52 and the unqualified product unloading platform 53 in the attached diagram are only for illustrative purposes; their actual positions can be the same as or interchanged with those in the attached diagram. It is recommended that qualified and unqualified products be placed in separate, categorized, and centrally unloaded sections.

[0032] The unloading robot 51 includes a multi-axis robot with lifting function, and the head of the multi-axis robot is equipped with multiple third suction nozzles. The number of the multiple third suction nozzles corresponds to the number of the second suction nozzles 423 on the product carrier 42, so that the third suction nozzles of the unloading robot 51 can transfer all the inspected products on the product carrier 42 to the qualified product unloading platform 52 or the unqualified product unloading platform 53 at one time.

[0033] Working process: The operator places the product 200 to be inspected on the tray 201, pulls out the drawer-type slide 112 of the loading platform 11, places the tray 201 on it, and then pushes it back to its original position. Alternatively, the empty tray 201 can be placed on the drawer-type slide 112 first, and then the product 200 can be placed in the tray 201. This order is not particularly restricted. The positioning camera 131 in the loading and positioning mechanism 13 scans and positions the product 200, providing feedback on the product position information to the loading robot 12. Based on the positioning information, the suction nozzle at the head of the loading robot 12 sequentially picks up and transfers the products 200 from the tray 201 to the transfer platform 21, placing them sequentially into the product slots 2121 of the carrier bracket 212. During this process... Previously, one of the platform supports 212, driven by the cylinder 213, moved along the guide rail 211 to the near-center position of the transfer platform 21 to receive the product 200. Once the product slot 2121 of this platform support 212 was full, it retracted to one end of the guide rail 211, and the other platform support 212 moved to the near-center position of the transfer platform 21 to take over loading the product 200. The two platform supports 212 alternately received the product, and the entire loading process was uninterrupted. Afterwards, the product 200 in the product slot 2121 of the platform support 212 was removed by the handling robot 22 and moved to the inspection station. The first suction nozzle 224 of the handling robot 22 was positioned on the X-axis linear module 221 and the Y-axis... Driven by the linear module 222, the product moves directly above the product 200. The lifting module 223 lowers the first suction nozzle 224 to adsorb the product 200, then raises it. The X-axis linear module 221 and Y-axis linear module 222 adjust the position and bring the product to the bottom visual inspection module station for bottom inspection. The fourth inspection camera 321 scans the bottom of the product 200 from below to check for defects. After the bottom inspection is completed, the transport robot brings the product 200 to the product carrier 42 on the conveying module 41. The second suction nozzle 423 takes over the product from the first suction nozzle 224 and adsorbs and fixes it. The conveying module 41 moves the product carrier 42 to below the first visual inspection mechanism, where the first inspection... Camera 311 scans the upper surface of product 200 to detect defects on the top surface. At the same time, the second detection camera 313 and the third detection camera 315 simultaneously perform side detection on opposite sides of product 200. After completion, motor 424 rotates to drive product to rotate 90 degrees. Then, the second detection camera 313 and the third detection camera 315 detect the other two sides of the product. After all detections are completed, product carrier 42 moves to the near unloading and sorting platform end of conveying moving module 41. The third suction nozzle in unloading robot 51 takes product 200 off product carrier 42 and sorts it according to the detection results, placing it in the tray on qualified product unloading platform 52 or unqualified product unloading platform 53, waiting for centralized unloading.
