Description

Technical Field

[0001] The utility model relates to the technical field of capacitor pins, in particular to a capacitor pin shaping device. Background Technique

[0002] A capacitor is a component that stores electric charge and electrical energy (electric potential energy). A conductor surrounded by another conductor, or a conductor system in which all the electric field lines emitted by one conductor terminate on another conductor, is called a capacitor. With the rapid development of electronic information technology, the replacement speed of digital electronic products is getting faster and faster. The production and sales volume of consumer electronic products mainly including flat-panel TVs (LCD and PDP), laptop computers, digital cameras, etc. continue to grow. Especially in integrated circuits, it is widely used, thus driving the growth of the capacitor industry.

[0003] The structure of a capacitor includes a container and two pins (i.e., an anode lead and a cathode lead). In order to install the capacitor on a circuit board, there are specific requirements for the distance between the two pins. After the pins pass through the through holes on the circuit board, the circuits on the circuit board are soldered to the pins using soldering. However, in the actual production process of capacitors, because there is a margin on the pins, soldering usually cannot completely cover them. Therefore, secondary trimming is required after soldering. However, the waste after trimming will accumulate on the processing table during long-term processing, affecting the subsequent capacitor processing and the normal operation of the equipment. Secondly, when multiple capacitors are processed at multiple workstations on a circular processing table, due to the certain inertia when the processing positions rotate, the capacitors will deviate from the predetermined positions, affecting the processing accuracy or directly falling off the workstations and becoming semi-finished products that are not completely processed.

The center of the lower surface of the upper limit ring 152 is fixedly connected to a rectangular telescopic rod 153, and the lower end of the rectangular telescopic rod 153 is fixedly connected to the upper limit ring 152. A second spring 154 is sleeved on the outer wall of the rectangular telescopic rod 153. The bottom surface of the upper limit ring 152 at the lower end is fixedly connected to a moving shaft 155.

[0027] First, use the motor to drive the moving shaft 155 and the collecting hopper 150 to rotate. At the same time, when the collecting hopper 150 rotates, the second special-shaped cam 151 on its lower surface interacts with the first special-shaped cam 112 to drive the entire collecting hopper 150 to move up and down. When the collecting hopper 150 rises, the second spring 154 is stretched. When the collecting hopper 150 descends, the second spring 154 rebounds and drives the collecting hopper 150 to return to its original position. Use the high-frequency vibration of the up-and-down movement of the collecting hopper 150 to vibrate and collect the pin waste on the surface of the wire mesh cover 160, prevent blockage, improve the degree of automation, and reduce the labor cost and cleaning intensity.

[0032] Please refer particularly to Figure 2 、 3 、4, the conical processing table 130 is in the shape of an inverted frustum, and the center of the bottom end of the conical processing table 130 is a through hole. The worm 135 is fixed on the upper surface of the bottom plate 100 through a fixing bracket, and a rubber anti-slip pad is fixedly arranged inside the lower clamping groove 131.

[0033] The center of the bottom end of the conical processing table 130 being a through hole can provide space for the operation of the collecting hopper 150. The rubber anti-slip pad fixedly arranged inside the lower clamping groove 131 can prevent damage to the capacitor due to excessive clamping force.

[0034] Please refer particularly to Figure 3 and Figure 4 , the fixing component 140 includes two groups of sliding rods 141. The sliding rods 141 penetrate and slide through the conical processing table 130. The upper ends of the sliding rods 141 are fixedly connected with clamping blocks 142, the lower ends of the sliding rods 141 are fixedly connected with connecting plates 144, the outer walls of the sliding rods 141 are sleeved with first springs 143, and the lower surfaces of the connecting plates 144 are fixedly connected with abutting rods 145.

[0035] The first spring 143 sleeved on the outer wall of the sliding rod 141 can provide a reset force for the fixing component 140, and the abutting rod 145 fixedly connected to the lower surface of the connecting plate 144 can cooperate with the abutting rod 145 to drive the fixing component 140 to automatically fix the capacitor.

[0036] Please refer particularly to Figure 2 and Figure 4 , the lower surface of the clamping block 142 is provided with an upper clamping groove 1421, and a rubber anti-slip pad is fixedly arranged inside the upper clamping groove 1421.

[0037] The lower surface of the clamping block 142 is provided with an upper clamping groove 1421, and the rubber anti-slip pad fixedly arranged inside the upper clamping groove 1421 can provide a fixing space for the capacitor, and the rubber anti-slip pad can prevent the capacitor from being damaged due to excessive clamping force.

[0038] Please refer particularly to Figures 1 to 3 , the upper end of the cushion ring 110 is fixedly connected with a plurality of convex blocks 111. The processing component 120 includes a feeding device 121, a rolling device 122, a first flipping device 123, a cutting device 124, a second flipping device 125 and an automatic discharging device 126, and each device is arranged at equal angles around the center. The upper end of the collecting hopper 150 is fixedly installed with a mesh cover 160.

The mesh cover 160 fixedly installed at the upper end of the collecting hopper 150 can prevent larger capacitors from falling into the inside of the collecting hopper 150.

[0040] First, use the motor to drive the moving shaft 155 and the collecting hopper 150 to rotate. At the same time, when the collecting hopper 150 rotates, the second special-shaped cam 151 on its lower surface and the first special-shaped cam 112 interact to drive the whole collecting hopper 150 to move up and down. When the collecting hopper 150 rises, the second spring 154 is stretched. When the collecting hopper 150 descends, the second spring 154 rebounds and drives the collecting hopper 150 to descend and reset. Use the high-frequency vibration of the up and down movement of the collecting hopper 150 to vibrate and collect the pin waste on the surface of the mesh cover 160, prevent blockage, improve the degree of automation, and reduce the labor cost of cleaning strength;

[0041] Secondly, another motor is used to drive the worm 135 to rotate. The worm 135 drives the worm gear 134 and the conical processing table 130 to rotate through meshing. While the conical processing table 130 is rotating, multiple abutting rods 145 all slide on the surface of the convex block 111. At the position between two adjacent processing devices, the abutting rod 145 is located between two adjacent convex blocks 111. At this time, the first spring 143 extends to drive the abutting rod 145 and the clamping block 142 to press downwards and cooperate with the lower clamping groove 131 to automatically fix the capacitor. When the abutting rod 145 is at the highest point of the convex block 111, it squeezes the first spring 143 upwards and the clamping block 142 releases the fixation of the capacitor, preventing the capacitor from shifting due to inertia during the conversion of workstations, resulting in an incomplete capacitor processing due to a vacant processing position and reducing the defective rate of processing.

[0042] Then, by using the cooperation between the convex block 111 and the abutting rod 145, the first special-shaped cam 112 and the second special-shaped cam 151, the automatic fixation during the capacitor processing is completed, reducing the setting of power sources such as air cylinders and reducing the energy cost.
