Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of capacitor production and processing, in particular to a capacitor element detection component. Background Art
[0002] China Authorization Announcement No. CN212207516U, with an authorization announcement date of December 22, 2020, discloses a capacitance detection device for a capacitor casing machine, comprising: a fixing mechanism for fixing a capacitor element on a conveyor line of the capacitor casing machine in the same position; a colloid detection mechanism for detecting the presence of colloid particles in the capacitor element, comprising a colloid detection component, a drive component, and a signal component. The drive component is connected to the colloid detection component and is used to drive the colloid detection component to periodically reciprocate axially. The front end of the colloid detection component points to the colloid position of the capacitor element and periodically moves axially toward the colloid. When the capacitor element has colloid particles and when it does not have colloid particles, the final position of the front end of the colloid detection component is different. The signal component is connected to the colloid detection component and sends an abnormal signal to the capacitor casing machine control panel when the colloid detection component is in the colloid-free position. The capacitance detection device provided by the utility model detects the presence of colloid particles through the colloid detection mechanism, and has a simple and reliable structure. In actual use, this existing technology has the following drawbacks: due to the relatively small size of the capacitor, the particle detection block must pass through the gap between the two pins before contacting the capacitor element. During this displacement, the particle detection block is prone to shaking, affecting the contact precision between the particle detection block and the element. This, on the one hand, affects the accuracy of detection; on the other hand, due to the lack of reset force, the element may be damaged; on the other hand, one leg of the capacitor may be bent. Given this situation, improvement is urgently needed. Utility Model Content

[0011] In order to further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention is described in further detail below in conjunction with specific implementation methods and accompanying drawings.

For example, they can refer to fixed connection, detachable connection, or integral connection; they can refer to mechanical connection or electrical connection; they can refer to direct connection or indirect connection through an intermediate medium; they can refer to internal communication between two components. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to the specific circumstances.
[0013] Reference Figure 1 The utility model provides a capacitor element detection component, including a drive component 22 and an assembly needle 16, and also includes a mounting platform 14, a mounting bracket 12, a proximity switch 13, a plunger 20, a buffer spring 21, a baffle 18, a bearing 15, a tension spring 17, and a buffer ejector pin 19; the mounting platform 14 is connected to the power output end of the drive component 22 through a connecting arm 24; the mounting bracket 12 is fixedly mounted on the mounting platform 14; the proximity switch 13 is mounted on the mounting bracket 12; the drive component 22 can be set as a cam drive motor or a lifting drive motor, and the proximity switch 13 is connected to the control system.
[0014] The plunger 20 is mounted on the top of the mounting bracket 12 and extends downward through the mounting bracket 12. A buffer spring 21 is coaxially arranged in the inner cavity of the plunger 20. The upper part of the buffer ejector pin 19 extends into the inner cavity of the plunger and is connected to the free end of the buffer spring 21. The free end of the buffer ejector pin 19 extends out of the plunger 20. The buffer ejector pin 19 is coaxially arranged with the plunger; the bearing 15 is fixedly mounted on the mounting platform 14 and is arranged through the mounting platform 14. The bearing 15 and the buffer ejector pin 19 are coaxially arranged. The baffle 18 is fixedly mounted on the top of the bearing 15 and its position matches the proximity switch 13; the assembly needle 16 sequentially passes through the baffle 18 and the bearing 15 and extends to the bottom of the bearing 15. The assembly needle 16 is fixedly connected to the baffle 18, and the assembly needle 16 is clearance-matched with the bearing 15; a tension spring 17 is installed between the lower surface of the baffle 18 and the upper surface of the mounting platform 14.
[0015] The plunger 20 is fixedly mounted on the mounting bracket 12 by means of positioning bolts 23. The bearing 15 is fixedly mounted on the mounting platform 14 by means of positioning bolts 23. By providing the positioning bolts 23, the installation stability of the plunger 20 and the bearing 15 is ensured.
[0016] Operation of this embodiment:
[0017] 1. The drive assembly 22 drives the mounting platform 14 to descend through the connecting arm 24;
[0018] 2. The assembly needle 16 is displaced in the direction of the capacitor;
[0019] 3. When the assembly needle 16 contacts the capacitor, the capacitor provides a reverse force on the assembly needle 16, thereby pushing the assembly needle 16 upward by a corresponding distance. The top of the assembly needle 16 contacts the lower end of the buffer ejector pin 19. If there is an element installed in the capacitor, the assembly needle 16 drives the baffle 18 to move up to the position corresponding to the proximity switch 13. The proximity switch 13 will feed back the signal to the control system, and the control system will then issue an instruction to the grasping structure of the processing equipment to transfer the capacitor with the element to the next process. If the proximity switch 13 fails to detect the baffle 18 normally, the proximity switch 13 will feed back the signal to the control system, and the control system will then issue an instruction to the grasping structure of the processing equipment to transfer the capacitor without the element to the defective collection box.
[0020] 4. After completing one detection, the drive assembly 22 drives the mounting platform 14 to rise and reset through the connecting arm 24. The baffle 18 drives the assembly needle 16 to reset under the force of the tension spring 17, preparing for the next element presence detection action.
[0021] In this embodiment, the bearing is fixedly mounted on the mounting platform and passes through the mounting platform. The bearing and the buffer ejector pin are coaxially arranged. The assembly needle and the bearing are clearance-matched, so that the assembly needle can stably achieve up and down displacement in the bearing. Combined with the matching structure of the buffer spring and the tension spring, the overall buffering effect of this structure is improved, thereby ensuring the detection accuracy without damaging the capacitor, thereby ensuring production quality.
[0022] The above-described embodiment merely represents one embodiment of the present invention. While the description is relatively specific and detailed, it should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
