Abstract
Description
Technical Field
[0001] This utility model relates to the field of capacitor core assembly technology, and in particular, to a capacitor core tilt detection device, a correction device, and an assembly system. Background Technology
[0002] The rubber plug of a capacitor is an important component of the capacitor. The materials of capacitor rubber plugs are diverse, generally including polypropylene, polystyrene, polyacrylate, silicone rubber, acrylate, EPDM rubber and their blends, etc., which have good corrosion resistance, insulation, heat resistance and weather resistance.
[0003] The main functions of capacitor rubber stoppers are as follows:
[0004] 1. Fixed electrodes: Capacitor plugs can fix the position and spacing of the electrodes, ensuring the stability of the capacitor's electrical performance.
[0005] 2. Preventing leakage: The dielectric inside a capacitor is susceptible to moisture and contamination, which can easily lead to leakage during operation. Using high-temperature resistant, corrosion-resistant, and highly insulating rubber stopper materials can effectively prevent leakage.
[0006] 3. Capacitor protection: Capacitor plugs can protect the internal electrodes of the capacitor from mechanical impact and prevent the capacitor from being damaged.
[0007] Therefore, the capacitor stopper is crucial for capacitors. However, in existing operating methods, during the assembly of semi-finished capacitors, the equipment needs to insert the core into the stopper and press the core down with a pressure rod to bond the core to the stopper. After normal assembly, however, the process is flawed. Figure 1 As shown. However, sometimes the core may tilt when inserted into the rubber stopper, as... Figure 2 As shown. This could cause the core to come into contact with the aluminum casing during insertion, leading to short circuit defects and the risk of being returned by the customer. Summary of the Invention

[0050] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this utility model will be described in detail below with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0051] Currently, after the rubber plug is installed into the capacitor core, it relies on manual inspection, which is slow and labor-intensive. Some technologies use cameras and image recognition to inspect the capacitor core, but these are costly and require the camera to accurately capture the core. If the shooting angle is incorrect, the capacitor core may be tilted, but the image recognition system may not detect it tilted, leading to missed detections.
[0052] Therefore, in order to solve the above problems, refer to Figure 3This utility model provides a capacitor core tilt detection device, including a placement unit 10 and a detection unit;
[0053] The placement unit 10 is used to place the capacitor core 20 upside down after the rubber plug is installed; wherein, upside down means that the rubber plug is at the bottom and the capacitor core 20 is at the top.
[0054] The detection unit includes a pressure rod 30, a limiting component, and a sensor. The limiting component is positioned above the pressure rod 30, so that the top of the pressure rod 30 can touch the limiting component when the pressure rod 30 increases in height. The sensor is selected according to actual needs, and its function is to emit a signal when the top of the pressure rod 30 touches the limiting component.
[0055] During testing, the bottom of the pressure rod 30 contacts the bottom of the capacitor core 20; wherein the bottom of the capacitor core 20 is the end without a lead or rubber plug.
[0056] When the capacitor core 20 is not tilted, the top of the pressure rod 30 does not contact the limiting component, and the sensor does not send a signal;
[0057] When the capacitor core 20 is tilted, the top of the pressure rod 30 contacts the limiting component, and the sensor sends a signal that the capacitor core 20 is defective.
[0058] like Figure 4 As shown, the placement unit 10 includes a limiting hole 11;
[0059] The top of the capacitor core 20 and the rubber plug are located in the limiting hole 11. The rubber plug is located in the limiting hole 11.
[0060] In one embodiment, the limiting hole 11 is provided with a strip-shaped slit;
[0061] The strip-shaped slot is used to place the pins of the capacitor core 20.
[0062] Therefore, when there are multiple guide pins, the multiple guide pins are located in a straight line. Therefore, a strip-shaped gap is set in the limiting hole 11 to facilitate the passage of the guide pins.
[0063] In another embodiment, the limiting hole 11 is provided with a needle hole;
[0064] The pin hole is used to place the pin of the capacitor core 20.
[0065] Understandably, when setting the needle hole, it is necessary to set it according to the specific number of needles and the interval between each needle, so in general, a strip gap is set.
[0066] The working process is as follows: After the capacitor core 20 with the rubber plug installed is placed in the limiting hole 11 of the placement unit 10, the placement unit 10 and the capacitor core 20 are moved to the detection station. After reaching the detection station, the pressure rod 30 is pressed down to directly above the capacitor core 20 and to a specified height (where the specified height is the height of the capacitor core 20 when it is not tilted). When the capacitor core 20 is not tilted, the capacitor core 20 will not cause the height of the pressure rod 30 to change, the top of the pressure rod 30 will not contact the limiting component, and the sensor will not send a signal. However, when the capacitor core 20 is tilted, since the rubber plug is located in the limiting hole 11, the rubber plug is not tilted (i.e., perpendicular to the placement unit 10), and the height of the capacitor core 20 increases relative to when it is not tilted. At this time, the capacitor core 20 will apply an upward force to the pressure rod 30, the height of the pressure rod 30 increases, the top of the pressure rod 30 contacts the limiting component, and the sensor sends a signal.
[0067] The detection device provided in this application includes a placement unit 10 and a detection unit; the placement unit 10 is used to invert the capacitor core 20 after the rubber stopper is installed; the detection unit includes a pressure rod 30, a limiting component, and a sensor; during detection, the bottom of the pressure rod 30 contacts the bottom of the capacitor core 20; when the capacitor core 20 is not tilted, the top of the pressure rod 30 does not contact the limiting component, and the sensor does not send a signal; when the capacitor core 20 is tilted, the top of the pressure rod 30 contacts the limiting component, and the sensor sends a signal that the capacitor core 20 is defective. This application solution is based on the fact that the height of the capacitor core 20 is different when it is tilted and when it is not tilted. A pressure rod 30 and a limiting component are set above the capacitor core 20. The height of the pressure rod 30 indicates the height of the capacitor core 20. Once the capacitor core 20 is tilted, the height of the pressure rod 30 increases, and when it touches the limiting component, the sensor alarms. This can effectively detect whether the capacitor core 20 is tilted, avoid the core from contacting the aluminum shell during the insertion process, eliminate the risk of short circuit defects and customer returns, and improve production efficiency.
[0068] However, the detection device in the above embodiment can directly reject a product as tilted to the defective product box, but since there is no product correction device, it is easy to cause waste and misjudgment. In order to better detect and correct the tilting defects of semi-finished products and reduce the core tilting defect rate and customer complaints, this application embodiment also provides a capacitor core tilting straightening device. It can effectively improve production efficiency and control customer complaints and core tilting defect rate.
[0069] refer to Figure 3 The capacitor core tilting and straightening device includes:
[0070] The capacitor core 20 tilt detection device provided in any of the above embodiments;
[0071] Correction unit;
[0072] The correction unit is used to move the capacitor core 20 so that the capacitor core 20 is perpendicular to the placement unit 10.
[0073] In one embodiment, the correction unit is a robotic arm used to straighten the tilted capacitor core 20. However, since the tilt angles of the capacitor cores 20 are different, the control of the robotic arm varies, making the straightening process relatively complex.
[0074] Therefore, in another embodiment, the correction unit includes a limiting clamp 50.
[0075] In one implementation, the limiting clamp 50 is a push rod. Its tilt angle is identified by image recognition, and then the angle and pushing length of the push rod are controlled to prevent the capacitor core 20 from tilting.
[0076] However, image recognition is costly. Therefore, in another implementation, the limiting clamp 50 includes two clamps, which are respectively disposed on both sides of the capacitor core 20.
[0077] like Figure 5 As shown, each limiting clamp 50 is provided with a slot 51 that matches the capacitor core 20;
[0078] During the correction process, the slots 51 of the two limiting clamps 50 fix the capacitor core 20 perpendicular to the placement unit 10.
[0079] The slots 51 of the two limiting clamps 50 form a vertical (i.e. perpendicular to the placement unit 10) channel. No matter how the capacitor core 20 is tilted, the capacitor core 20 can be straightened when the two limiting clamps 50 close from both sides.
[0080] To prevent the rubber plug from detaching from the capacitor core 20, such as Figure 6 As shown, the pressure rod 30 in this application includes a pressure plate 31 and a spring 32;
[0081] The pressure plate 31 is provided with the bottom of the pressure rod 30, which is in contact with the capacitor core 20;
[0082] One end of the spring 32 is fixed to the pressure rod 30, and the other end is located below the limiting component;
[0083] When the capacitor core 20 is not tilted, the other end of the spring 32 is not in contact with the limiting component.
[0084] When the capacitor core 20 is tilted, the other end of the spring 32 contacts the limiting component;
[0085] When the other end of the spring 32 contacts the limiting component, the spring 32 is in a compressed state so that the spring 32 provides a downward force to the capacitor core 20 through the pressure plate 31, pushing the capacitor core 20 to fit tightly against the rubber stopper.
[0086] When the limit clamp 50 closes, the pressure rod 30 presses the capacitor core 20 against the rubber stopper through the spring 32 and the pressure plate 31, preventing the capacitor core 20 from falling off and improving production quality.
[0087] It should be noted that the two limit clamps 50 are driven by the cylinder 70. The pressure rod 30 is movably mounted on one of the limit clamps 50, meaning that the height of the pressure rod 30 can be raised when the capacitor core 20 is tilted.
[0088] The capacitor core tilt correction device provided in this application embodiment can not only detect whether the capacitor core 20 is tilted after the rubber plug is installed on it, but also correct the capacitor core 20 when it is tilted, which greatly improves the production quality.
[0089] Based on the same inventive concept, such as Figure 7 As shown in the embodiments of this application, a capacitor core assembly system is also provided, including: a capacitor core tilting and straightening device and a turntable as provided in any of the above embodiments.
[0090] The turntable 60 is equipped with multiple placement units 10. A robotic arm places the capacitor core 20 with the rubber plug installed on the placement unit 10 of the turntable 60. Then the turntable 60 rotates to send the capacitor core 20 to the detection device or correction device for detection or correction.
