Technical Field
[0001] This utility model relates to the field of capacitor production equipment technology, and in particular to a discharge detection device. Background Technology
[0002] As a key component widely used in electronic devices, capacitors' performance and reliability directly affect the overall quality of the device. During capacitor production, aging tests are required to screen out defective products and prevent them from entering the market. After the aging test, capacitors typically undergo a visual inspection using a combination of manual and semi-automatic equipment; only those that pass the visual inspection are released for the next process.
[0003] However, these semi-automated discharge detection devices still rely on manual labor, which not only has a high false detection rate but also increases labor costs. Utility Model Content
[0004] In view of this, the present invention provides a discharge detection device to solve the problem that the discharge detection devices in the prior art still rely on manual labor, which not only has a high false detection rate, but also increases labor costs.
[0005] To achieve one, some, or all of the above objectives, or other objectives, this utility model proposes a discharge detection device, including a base and a clamping arm. The base is respectively equipped with a rotary drive and a camera detection component. A rotating head is coaxially connected to the output shaft of the rotary drive. The clamping arm is disposed on the rotating head and arranged radially outwards along the rotating head. The clamping arm sequentially has a picking station, a detection station, and a discharge station along the rotation trajectory of the rotating head. The camera detection component is located at the detection station. The discharge station includes a defective appearance rejection station and a dropping station. Collection containers are provided below both the defective appearance rejection station and the dropping station. The clamping arm performs the following sequential actions during rotation: picking up capacitors at the picking station; determining good / defective products at the detection station using the camera detection component; and, based on the determination result, selecting whether to transport the capacitors to the dropping station and release them into the corresponding collection container, or to release them into the corresponding collection container at the defective appearance rejection station.
[0006] Preferably, the camera inspection assembly includes a bracket, a front-view camera, and two side-view cameras. The bracket is fixedly mounted on one side of the base. The front-view camera and the two side-view cameras are both mounted on the bracket. The front-view camera faces the rotating head and is arranged radially along the rotating head. The two side-view cameras are symmetrically distributed on both sides of the front-view camera along the axial direction of the rotating head. The optical axes of the front-view camera and the two side-view cameras intersect at the inspection station.
[0007] Preferably, each of the front-view camera and the two side-view cameras is equipped with a fill light in front of its lens. The fill lights are distributed around the lens of the corresponding camera in a circumferential manner, and the illumination direction is in the same direction as the optical axis of the corresponding camera.
[0008] Preferably, the optical axis of the side-view camera is tilted at an angle of 30°-60° to the optical axis of the front-view camera, and a reflector is provided in front of the lens of each side-view camera. The side-view camera can capture the side image of the capacitor located at the detection station by reflecting the corresponding reflector.
[0009] Preferably, the clamping arm includes two arms and an elastic element. The rear ends of both arms are hinged to one side wall of the rotating head, and the hinged ends of the two arms are engaged by gear teeth. The hinge axes of both arms are perpendicular to the axis of the rotating head. The elastic element is disposed between the two arms and is used to drive the front ends of the two arms to abut against each other. A transmission arm extends from the rear end of one of the arms. A roller is rotatably provided on the transmission arm, and the axis of the roller intersects the axis of the rotating head. Three opening and closing cylinders are distributed on the base along the circumference of the rotating head. The opening and closing cylinders are in the same direction as the rotary drive component and are aligned with the material handling station. The defective rejection station and the unloading station are set up one-to-one. The extension and retraction ends of the opening and closing cylinders are equipped with top blocks, and the base is also equipped with arc-shaped transition blocks. When the clamping arm is in the material picking station, the defective rejection station, or the unloading station, the corresponding opening and closing cylinder can drive the top block to squeeze the roller. The transmission arm drives the two arms to swing open synchronously, so that the front ends of the two are separated. When the top block corresponding to the unloading station drives the arm to open, the rotary drive can drive the roller to roll along the outer wall of the transition block, so that the clamping arm, while in the open state, transitions from the top block corresponding to the unloading station to the top block corresponding to the picking station.
[0010] Preferably, the top block corresponding to the material picking station is provided with a closed inclined surface. When the clamping arm rotates from the material picking station to the detection station, the roller will roll along the closed inclined surface until the elastic element drives the two arm rods to close.
[0011] Preferably, the clamping arms are provided in multiple ways, and the multiple clamping arms are evenly distributed along the circumference of the rotating head. Each clamping arm passes through the material picking station, the inspection station, the appearance defect rejection station and the unloading station in sequence as the rotating head rotates.
[0012] Preferably, the discharge detection device further includes a collection box, a receiving cylinder, and a receiving hopper. The rotary drive is horizontally arranged, and the defective rejection station is located on one side of the rotating head in the horizontal direction. The collection box and the receiving cylinder are both fixedly arranged on one side wall of the base in the horizontal direction. The receiving cylinder is located above the collection box, and the receiving hopper is inclinedly arranged on the telescopic end of the receiving cylinder. The receiving cylinder can control the receiving hopper to retract to avoid the clamping arm, or extend so that its upper end extends directly below the defective rejection station.
[0013] Preferably, the discharge detection device further includes a positioning sensor, and the rotary drive component achieves steering positioning through the positioning sensor.
[0014] Preferably, the positioning sensor includes a wheel and a photoelectric switch. The wheel is fixedly mounted on the output shaft of the rotary drive component. Four notches are evenly distributed along the axial direction on the wheel. The notches correspond one-to-one with the material picking station, the inspection station, the defective appearance rejection station, and the unloading station. The photoelectric switch is mounted on the base and adjacent to the wheel. The edge of the wheel is located in the optical path between the transmitting end and the receiving end of the photoelectric switch.
[0015] Implementing the embodiments of this utility model will have the following beneficial effects:
[0016] After adopting the above-mentioned discharge inspection device, during use, the clamping arm rotates and sequentially completes the following steps: at the material handling station, it clamps the capacitors that have completed the aging test; at the inspection station, the camera inspection component determines whether the capacitors are good or defective based on their appearance; and based on the determination result, it selects to transport the capacitors to the unloading station to release them into the corresponding collection container or to the appearance defect rejection station to release them into the corresponding collection container for centralized processing.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and accompanying drawings of this invention are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or accompanying drawings of this invention are used to distinguish different objects, not to describe a particular order.
[0026] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0027] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
[0028] like Figure 1-5As shown, a material discharge detection device includes a base 1 and a clamping arm 2. A rotary drive 11 and a camera detection assembly 3 are respectively mounted on the base 1. The rotary drive 11 can be a motor, a divider, or other device with an output shaft that can drive the output shaft to rotate. In this embodiment, a motor is preferred. A rotating head 12 is coaxially connected to the output shaft of the rotary drive 11. The clamping arm 2 is mounted on the rotating head 12 and is arranged radially outward along the rotating head 12. The clamping arm 2 has a material picking station, a detection station, and a material discharge station sequentially along the rotation trajectory of the rotating head 12. The camera detection assembly 3 is located at the detection station. The material discharge station includes a defective material rejection station and a material unloading station. In addition to the collection containers (not shown in the attached diagram) located below both the loading and unloading stations, the clamping arm 2 performs the following sequentially during rotation: at the loading station, it picks up capacitors that have completed the aging test; at the inspection station, the camera inspection component 3 determines whether the capacitors are good or defective based on their appearance; and based on the determination result, it selects to transport the capacitors to the unloading station and release them into the corresponding collection container, or to release them into the corresponding collection container at the defective appearance rejection station for centralized processing. Using the rotating clamping arm 2 to replace manual handling and using the camera inspection component 3 to replace human eyes to screen for defective products not only saves labor costs, but also eliminates interference factors such as visual fatigue in camera inspection, making the inspection results more accurate and reliable, and effectively reducing the false detection rate.
[0029] Specifically, the appearance information acquired by the camera detection component 3 will be analyzed and judged by the control cabinet. Both the camera detection component 3 and the control cabinet can be purchased through market channels, and will not be described in this embodiment.
[0030] Furthermore, the camera inspection component 3 includes a bracket 31, a front-view camera 32, and two side-view cameras 33. The bracket 31 is fixedly mounted on one side of the base 1. The front-view camera 32 and the two side-view cameras 33 are all mounted on the bracket 31. The front-view camera 32 faces the rotating head 12 and is arranged radially along the rotating head 12. The two side-view cameras 33 are symmetrically distributed on both sides of the front-view camera 32 along the axial direction of the rotating head 12. The optical axes of the front-view camera 32 and the two side-view cameras 33 intersect at the inspection station. When the clamping arm 2 rotates with the rotating head 12 to the inspection station, the front-view camera 32 will take a picture of the end of the capacitor away from the pin, while the two side-view cameras 33 will take pictures of both sides of the capacitor respectively. By taking pictures from multiple angles, the surface information of the capacitor can be obtained to the greatest extent, thereby improving the accuracy of the inspection.
[0031] Furthermore, each of the front-viewing camera 32 and the two side-viewing cameras 33 is equipped with a supplementary light 34 in front of its lens. The supplementary lights 34 are distributed around the lens of the corresponding camera and the illumination direction is in the same direction as the optical axis of the corresponding camera. The supplementary lights 34 illuminate various parts of the capacitor to be tested so that the camera can obtain more detailed information about the capacitor and ensure the accuracy of the detection.
[0032] Furthermore, the optical axis of the lens of the side-view camera 33 is tilted at an angle of 30°-60° to the optical axis of the lens of the front-view camera 32, and a reflector 35 is provided in front of the lens of the side-view camera 33. The side-view lens can take pictures of the side of the capacitor to be tested through the reflector 35. At the same time, tilting the side-view lens to both sides of the main view lens can make the overall camera detection assembly 3 more compact, reduce the space occupation, and make the output detection device adapt to the compact processing environment.
[0033] Furthermore, the clamping arm 2 includes two arm rods 21 and an elastic element 22. In this embodiment, the elastic element 22 is preferably a spring. The rear ends of both arm rods 21 are hinged to one side wall of the rotating head 12, and the hinge ends of the two arm rods 21 are engaged by gear teeth 23. The hinge axes of both are perpendicular to the axis of the rotating head 12. The elastic element 22 is disposed between the two arm rods 21 and is used to drive the front ends of the two arm rods 21 to abut against each other. The rear end of one arm rod 21 extends and is connected to a transmission arm 24. Rollers 25 are rotatably mounted on the base 24, and the axis of the rollers 25 intersects the axis of the rotating head 12. Three opening and closing cylinders 13 are distributed on the base 1 along the circumference of the rotating head 12. The opening and closing cylinders 13 are in the same direction as the rotating drive component 11 and are set one by one with the material picking station, the appearance defect rejection station, and the material dropping station. Each of the extension and retraction ends of the opening and closing cylinders 13 is provided with a top block 14. The base 1 is also provided with an arc-shaped transition block 15. When the clamping arm 2 is in the material picking station, the appearance defect rejection station, or the material dropping station, The corresponding opening and closing cylinder 13 can drive the top block 14 to squeeze the roller 25, and drive the two arms 21 to swing open synchronously through the transmission arm 24, so that the front ends of the two arms are separated, so as to control the clamping arm 2 to clamp the capacitor to be tested or release the capacitor after testing. When the top block 14 corresponding to the unloading station drives the arm 21 to open, the rotary drive component 11 can drive the roller 25 to roll along the outer wall of the transition block 15, so that the clamping arm 2, while in the open state, is transitioned from the top block 14 corresponding to the unloading station to the top block 14 corresponding to the picking station, so that the lead of the capacitor to be tested on the conveyor belt can be extended into the front ends of the two arms 21, avoiding the clamping arm 2 colliding with the lead of the capacitor during the picking process. After that, the cylinder corresponding to the picking station only needs to release the squeeze on the transmission arm 24, and the two arms 21 will swing and close synchronously under the drive of the elastic component 22 and the transmission of the gear, and clamp the lead of the capacitor through its closed front end, thereby completing the gripping of the capacitor to be tested. The same applies when releasing the capacitor after testing.
[0034] Furthermore, a closed inclined surface 141 is provided on the top block 14 corresponding to the material picking station. When the clamping arm 2 rotates from the material picking station to the inspection station, the roller 25 will roll along the closed inclined surface 141 until the elastic element 22 drives the two arms 21 to close. In actual use, the aging test device and the discharge inspection device are linked and controlled by the control cabinet. When the capacitor fails the aging test, the opening and closing cylinder 13 corresponding to the material picking station will not retract, and the clamping arm 2 will not close to grab the unqualified capacitor. The rotating head 12 will continue to rotate, so that the roller 25 rolls along the closed inclined surface 141 to help the clamping arm 2 transition to the closed state, prevent the front end of the arm 21 from being pulled by the elastic element 22 and cause a rapid impact, and extend the service life of the arm 21.
[0035] Furthermore, multiple clamping arms 2 are provided, and the multiple clamping arms 2 are evenly distributed along the circumference of the rotating head 12. Each clamping arm 2 passes through the material picking station, the inspection station, the appearance defect rejection station and the unloading station in sequence as the rotating head 12 rotates, so that the four stations work continuously and improve the production efficiency of the material output inspection device.
[0036] Furthermore, the discharge detection device also includes a collection box 41, a receiving cylinder 42, and a receiving hopper 43. The rotary drive 11 is horizontally arranged, and the defective rejection station is located on one side of the rotating head 12 in the horizontal direction. The collection box 41 and the receiving cylinder 42 are both fixedly arranged on one side wall of the base 1 in the horizontal direction. The receiving cylinder 42 is located above the collection box 41, and the receiving hopper 43 is inclinedly arranged on the telescopic end of the receiving cylinder 42. Under normal conditions, the receiving cylinder 42 controls the receiving hopper 43 to retract above the collection box 41 to avoid the clamping arm 2. When the clamping arm 2 needs to release the qualified capacitor, the receiving cylinder 42 will control the receiving hopper 43 to extend, so that its upper end extends directly below the defective rejection station, so as to guide the capacitor released by the clamping arm 2 into the collection box 41 for collection.
[0037] Furthermore, the discharge detection device also includes a positioning sensor, and the rotary drive 11 achieves steering positioning through the positioning sensor.
[0038] In one embodiment, the positioning sensor includes a detection element and a sensing element. The detection element is an eccentric wheel, and the sensing element is a mechanical switch such as a micro switch. The eccentric wheel is coaxially mounted on the output shaft of the rotary drive 11. There are four sensing elements, which are distributed around the output shaft of the rotary drive 11 in a one-to-one correspondence with each station. When the eccentric wheel rotates and its eccentric end abuts against the micro switch, the micro switch can be triggered, thereby stopping the rotary drive 11 through the micro switch and realizing the steering positioning of the clamping arm 2 (not shown in the figure).
[0039] Furthermore, the positioning sensor includes a wheel 5 and a photoelectric switch 6. The wheel 5 is fixedly mounted on the output shaft of the rotary drive 11. Four notches 51 are evenly distributed along the axial direction on the wheel 5. The notches 51 correspond one-to-one with the material picking station, the inspection station, the appearance defect rejection station, and the unloading station. The photoelectric switch 6 is mounted on the base 1 and is adjacent to the wheel 5. The edge of the wheel 5 is located in the optical path between the transmitting end and the receiving end of the photoelectric switch. Under normal conditions, the edge of the wheel 5 blocks the transmitting end and the receiving end of the photoelectric switch 6. However, when the output shaft of the rotary drive 11 rotates, it will drive the wheel 5 to rotate. When the notch 51 rotates to the photoelectric switch 6, the transmitting end and the receiving end of the photoelectric switch will be connected through the notch 51. At this time, the rotary drive 11 stops rotating, thereby helping the clamping arm 2 to achieve steering positioning.
