Description

Technical Field

[0001] This utility model relates to the field of capacitor bending technology, specifically a bending device for capacitor processing. Background Technology

[0002] Capacitors are of paramount importance. Today, most electronic products, such as computers, mobile phones, and digital recorders, are closely related to capacitors. In the process of capacitor manufacturing, the capacitor leads need to be bent. Currently, the bending process is mostly done manually, which is difficult and inefficient. Nowadays, capacitor lead bending machines are mostly used.

[0003] According to a public announcement of a capacitor processing bending machine (announcement number: CN219924389U), the above application includes a conveyor belt fixed by a support column, a positioning line fixed by a fixing plate above the conveyor belt, a baffle for resisting force below the positioning line, and a movable bending mechanism for bending the capacitor above the conveyor belt.

[0004] However, the aforementioned bending machine lacks guidance for the capacitors during actual use, resulting in inconsistent bending directions of the leads on each capacitor. This leads to uneven component arrangement, affecting the appearance. In automated component insertion processes, precise alignment of component leads with PCB holes is required. Inconsistent bending directions can cause downstream automated insertion or inspection equipment to fail to recognize the components, requiring operators to spend extra time realigning the leads or manually correcting them, thus impacting assembly efficiency. Therefore, we propose a bending device for capacitor processing. Utility Model Content

[0005] The purpose of this invention is to provide a bending device for capacitor processing to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a bending device for capacitor processing, comprising a frame, a drive motor fixedly connected to the side wall of the frame, a drive shaft fixedly connected to the output end of the drive motor, a conveyor belt drivingly connected to the side wall of the drive shaft, and a bending assembly disposed above the conveyor belt, the bending assembly comprising:

[0007] A placement slot is provided on the top end face of the conveyor belt;

[0008] The mounting frame has an electric push rod fixedly connected to its top end face, and a movable frame is fixedly connected to the output end of the electric push rod.

[0009] Connecting frame one, with a guide arc plate fixedly connected to its end face; connecting frame two, with a bending plate fixedly connected to its end face;

[0010] Preferably, the number of placement slots is set to several groups, the several groups of placement slots are arranged at equal intervals, and the placement slots are inserted into the capacitors.

[0011] Preferably, the mounting bracket is fixedly connected to the side wall of the frame, and the movable bracket is located directly above the conveyor belt.

[0012] Preferably, the connecting frame is fixedly connected to the bottom end face of the movable frame, and the guide arc plate is movably connected to the lead of the capacitor.

[0013] Preferably, there are two sets of guide arc plates, which are staggered and positioned directly below the movable frame. The staggered guide arc plates guide the leads of the capacitors, ensuring that the angle of each capacitor remains consistent.

[0014] Preferably, the cross-section of the bending plate on the side near the guide arc plate is vertical, and the cross-section of the bending plate on the side away from the guide arc plate is L-shaped. The bending plate slowly guides the capacitor pins as they pass, causing the pins to gradually bend into an L-shape, which facilitates horizontal installation or flat welding.

[0015] Preferably, a limiting frame is fixedly connected to the side wall of the guide arc plate, the bottom of the limiting frame is movably connected to the top end face of the capacitor, and the inner wall of the limiting frame is movably connected to the pin.

[0016] Compared with the prior art, the present invention provides a bending device for capacitor processing, which has the following advantages:

[0017] 1. This capacitor processing bending device, through its bending components and electric push rods, adjusts the height of the guide arc plates and bending plates, allowing the device to adapt to capacitors of different specifications. Adjusting the height ensures pin bending accuracy and improves consistency. The guide arc plates stagger the capacitor pins, forcing them into standard positions and angles during the guiding process, ensuring consistent angles for each capacitor. This maintains consistency in the bending start point, direction, and angle. The bending plates ensure uniform force distribution on the pins during plastic deformation, preventing pin breakage and stress damage. Simultaneously, the slow guiding ensures each pin completes bending along the same path, angle, and position, resulting in uniform pin length, neatness, and aesthetics after forming, facilitating subsequent inspection and verification.

[0018] 2. The bending device for capacitor processing, through the setting of a limiting frame, always limits the capacitor during the bending process of the leads, prevents the capacitor from rotating or deviating during the bending process, suppresses the rotation trend, ensures the stability of the capacitor posture, and improves the bending accuracy.

[0024] like Figures 1-4 As shown, this utility model provides a technical solution: a bending device for capacitor processing, including a frame 1, a drive motor 2 fixedly connected to the side wall of the frame 1, a drive shaft 3 fixedly connected to the output end of the drive motor 2, a conveyor belt 4 connected to the side wall of the drive shaft 3, and a bending assembly 5 arranged above the conveyor belt 4. The bending assembly 5 includes a placement groove 501, a mounting frame 502, an electric push rod 503, a movable frame 504, a first connecting frame 505, a guide arc plate 506, a second connecting frame 507, and a bending plate 508.

[0025] In one embodiment of this utility model, a placement slot 501 is formed on the top end face of the conveyor belt 4. The number of placement slots 501 is set in several groups, and the several groups of placement slots 501 are arranged at equal intervals. The placement slot 501 is inserted into the capacitor. The mounting frame 502 is fixedly connected to the side wall of the frame 1. An electric push rod 503 is fixedly connected to the top end face of the mounting frame 502. A movable frame 504 is fixedly connected to the output end of the electric push rod 503. The movable frame 504 is located directly above the conveyor belt 4.

[0026] Connecting frame 1 505 is fixedly connected to the bottom end face of movable frame 504. A guide arc plate 506 is fixedly connected to the end face of connecting frame 1 505. The guide arc plate 506 is movably connected to the lead of the capacitor. There are two sets of guide arc plates 506, which are staggered and positioned directly below movable frame 504. The staggered guide arc plates 506 guide the lead of the capacitor to keep the angle of each capacitor consistent. Connecting frame 2 507 is fixedly connected to the bottom end face of movable frame 504. A bending plate 508 is fixedly connected to the end face of connecting frame 2 507. The cross-section of the bending plate 508 on the side near the guide arc plate 506 is vertical, and the cross-section on the side away from the guide arc plate 506 is L-shaped. The bending plate 508 slowly guides the capacitor pins as they pass by, causing the pins to gradually bend into an L-shape, which is convenient for horizontal installation or flat welding.

[0027] The drive motor 2 drives the drive shaft 3 to rotate, which in turn causes the conveyor belt 4 to move, carrying the capacitor and moving it horizontally on the conveyor belt 4. The capacitor passes through the bending assembly 5, and the placement groove 501 is used to fix the capacitor and prevent the capacitor from shifting during the bending process. The electric push rod 503 adjusts the height of the guide arc plate 506 and the bending plate 508, so that the device can be adapted to capacitors of different specifications. After adjusting the height, the bending accuracy of the leads is ensured and the consistency is improved.

[0028] The capacitor and its pins are in contact with the guide arc plate 506. The guide arc plate 506 guides the capacitor pins in an alternating manner, so that the two pins are forced into the standard position and angle during the guiding process. The angle of each capacitor is consistent, thereby making the bending start point, direction and angle consistent, improving the efficiency of subsequent automated insertion and welding.

[0029] The capacitor being corrected reaches the bending plate 508, which slowly guides the capacitor pins, gradually bending them into an L-shape. This facilitates horizontal mounting or flat soldering. The slow guiding method ensures that the pins are subjected to uniform force during plastic deformation, preventing pin breakage and stress damage. At the same time, the slow guiding method ensures that each pin completes the bending along the same path, angle, and position, resulting in consistent pin lengths, neat appearance, and convenient subsequent testing and insertion.

[0030] In addition, the side wall of the guide arc plate 506 is fixedly connected to the limiting frame 6. The bottom of the limiting frame 6 is movably connected to the top end face of the capacitor, and the inner wall of the limiting frame 6 is movably connected to the pin. By limiting the pin with the limiting frame 6, the limiting frame 6 always limits the capacitor during the bending process, preventing the capacitor from rotating or shifting during the bending process, suppressing the rotation trend, ensuring the stability of the capacitor posture, improving the bending accuracy, preventing pin asymmetry, angle deviation, and skew, and improving the shape consistency of the pin after bending.

[0031] In this invention, during use, the drive motor 2 drives the drive shaft 3 to rotate, which in turn causes the conveyor belt 4 to move, carrying the capacitor on the conveyor belt 4 and allowing it to pass through the bending assembly 5. The placement groove 501 is used to fix the capacitor and prevent displacement during the bending process. The electric push rod 503 adjusts the height of the guide arc plate 506 and the bending plate 508, allowing the device to adapt to capacitors of different specifications. The capacitor and its pins are in contact with the guide arc plate 506. The guide arc plate 506 guides the capacitor pins in an alternating manner, forcing the two pins into the standard position and angle during the guiding process. The angle of each capacitor is consistent, thus ensuring that the bending start point, direction, and angle are consistent. The corrected capacitor reaches the bending plate 508, which slowly guides the passing capacitor pins, gradually bending them into an L-shape for easy horizontal installation or flat welding. The slow guiding and forming method allows the pins to be subjected to uniform force during plastic deformation, resulting in consistent pin lengths after forming.

[0032] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
