Description

Technical Field

[0001] The utility model relates to the technical field of capacitor processing, in particular to an automatic leg cutting machine for bulk capacitors. Background Art

[0002] Capacitors, also known as capacitors, are components that hold electric charges. In existing capacitor production, the pins of capacitors produced are often relatively long. If the capacitors are not trimmed accordingly, they will be easily bent or even broken during transportation, thus affecting the product yield. The existing capacitor pin trimming work is done by operators manually measuring the pin length while performing manual pin trimming. Only after repeated measurements and trimming can the pin length be adjusted to the exact length actually required. Not only is the operation time-consuming and laborious, it is also impossible to ensure the consistency of the length of each capacitor pin. Moreover, if the pin is cut too short during adjustment, the capacitor cannot be used and is directly scrapped. Utility Model Content

[0024] The utility model is described in detail below with reference to the accompanying drawings.

[0025] like Figures 1 to 3As shown, the utility model is an automatic bulk capacitor foot trimming machine, comprising a machine base 1, a feeding device 2 arranged at one end of the machine base 1, a pressing device 3 used in conjunction with the feeding device 2, a first shearing device 4 arranged on both sides of the feeding device 2, a second shearing device 5 and a discharge ramp 6 arranged at the other end of the machine base 1, the feeding device 2 is used for conveying capacitors to be trimmed, the pressing device 3 is used for pressing and positioning the capacitors to be trimmed on the feeding device 2, and the first shearing device 4 and the second shearing device 5 are used for trimming the capacitors that are pressed and positioned by the pressing device 3.

[0026] Before work, it is necessary to refer to the SOP system to check the material number of the parts, and confirm the size of the shearing foot first, and place the bulk capacitors on the feeding device 2. The machine base 1 is provided with a speed regulating knob for adjusting the feeding speed of the feeding device 2, a first control switch for opening or closing the feeding device 2, and a second control switch for simultaneously opening or closing the first shearing device 4 and the second shearing device 5, and a main power switch. The operator starts the entire shearing machine by pressing the main power switch, and then presses the first control switch to start the normal operation of the feeding device 2. The feeding speed of the feeding device 2 is controlled and adjusted by rotating the speed regulating knob. The degree of automated control is high. After adjustment, the machine is started to test run the first capacitor, and measure whether the shearing foot length meets the standard. After further adjustment, the appropriate feeding speed is adjusted to facilitate large-scale processing. During operation, the capacitor is transported through the feeding device 2, and the pins of each capacitor are exposed from the feeding device 2. When the capacitor reaches between the first shearing device 4 and the second shearing device 5, the operator presses the first control switch again to shut down the operation of the feeding device 2. Then the pressing device 3 presses the capacitor downward to fix the capacitor in the feeding device 2, effectively preventing the capacitor from being offset and skewed during the shearing process, which affects the shearing quality. The operator presses the second control switch to start the first shearing device 4 and the second shearing device 5. The first shearing device 4 and the second shearing device 5 are close to each other to form a shearing force, and then the capacitor pins that are held and positioned by the pressing device 3 are sheared. In the next step, the capacitor that has completed the shearing work is placed in an electrostatic bag, and the corresponding material number is written on it for sealing. The utility model realizes the automatic shearing of capacitors, can adjust the length of the pins to a standard length, ensures the consistency of the length of each capacitor pin, saves time and effort in operation, and improves product quality.

[0027] The first shearing device 4 of this embodiment has the same structure as the second shearing device 5. The first shearing device 4 includes a stand 41, a base 42 arranged on the stand 41, a driving cylinder 43 arranged on the base 42, and a shearing knife 44 driven and connected to the driving cylinder 43. The stand 41 is provided with a mounting groove 45 and a mounting screw 46 arranged in the mounting groove 45. The base 42 is provided with a mounting hole 47. There are a plurality of mounting holes 47, and the plurality of mounting holes 47 are arranged at intervals along the height direction of the base 42. The mounting screw 46 passes through the mounting groove 45 and is connected to the mounting hole 47. Specifically, before work, it is necessary to refer to the SOP system to check the material number of the capacitor, first adjust the height position of the base 42 relative to the stand 41 according to the shear pin size of the capacitor, and then use the mounting screw 46 to pass through the mounting slot 45 and connect to the mounting hole 47, so as to fix the position of the base 42 after the height adjustment, so as to drive the cylinder 43 to drive the shear knife 44 to shear the pins of the capacitor horizontally. There are two stands 41, and the two stands 41 are respectively fitted and abutted on both sides of the base 42, with strong support and bearing stability and good positioning effect. The inner sides of the shear knife 44 of the first shearing device 4 and the shear knife 44 of the second shearing device 5 are shearing slopes that match each other, and the shearing area is large, which is conducive to completely shearing the pins of the capacitor in a short time.

[0028] In this embodiment, a waste material box 7 for collecting sheared pin waste is provided between the first shearing device 4 and the second shearing device 5, and the waste material box 7 is located below the feeding device 2. Specifically, the waste material box 7 is located between the first shearing device 4 and the second shearing device 5, which is convenient for uniformly collecting the pin waste generated in the process of shearing pins, ensuring the cleanliness of the working environment and eliminating the trouble of cleaning and tidying.

[0029] The outer side of the base 42 of this embodiment is provided with a scale 48. Specifically, when adjusting the height position of the base 42 relative to the stand 41, the height position of the base 42 can be intuitively known through the scale 48, thereby improving the adjustment accuracy and being simple and convenient to use.

[0030] The pressing device 3 of this embodiment includes a lifting cylinder 31, a connecting plate 32 drivingly connected to the lifting cylinder 31, and a pressing plate 33 arranged on the connecting plate 32, and the pressing plate 33 is driven by the lifting cylinder 31 to move up and down relative to the feeding device 2. Specifically, the lifting cylinder 31 drives the pressing plate 33 to move up and down through the connecting plate 32, and the pressing plate 33 is pressed against the top of the capacitor to fix the position of the capacitor in the feeding device 2.

[0031] The feeding device 2 of this embodiment includes a base 21, a vibration motor 22 disposed at the bottom of the base 21, and a feeding track 23 disposed at the top of the base 21. Specifically, the feeding device 2 is a horizontal feeder of the prior art, which utilizes the vibration force generated by the vibration motor 22 to make the capacitor in the feeding track 23 vibrate periodically, thereby moving along the linear direction of the feeding track 23 to ensure smooth transportation and precise positioning of the capacitor.
