Description

Technical Field

[0001] The utility model relates to capacitor manufacturing equipment, in particular to a component leg straightening mechanism. Background Art

[0002] During the process of transferring the capacitor element on the disc, the centrifugal force generated by the rotation of the disc will cause the capacitor element body to tilt and shake. When the subsequent rubber cover is pressed in, the equipment's pressing mechanism directly presses the element pin into the rubber cover hole, which will cause the rubber cover and the capacitor element to be pressed in at an angle when they are tightly combined, causing the element to be damaged and deformed.

[0003] In order to solve the above-mentioned technical problems, a Chinese patent with patent number CN202021617843.3 discloses an assembled foot-pulling and straightening mechanism, including a base, on which a foot-pulling device and a straightening device are provided, the straightening device is provided with a straightening clamp, and the straightening clamp is used to clamp and straighten the element body; the foot-pulling device includes a foot-pulling clamp and a foot-pulling middle mold, the foot-pulling clamp is used to clamp and lift the element guide pin, the foot-pulling middle mold is located in the middle position of the foot-pulling clamp, and is used to assist the foot-pulling clamp to complete the actions of clamping the guide pin and lifting the guide pin, while sharing the force and providing support for pressing the rubber cover into the element body. The assembly foot-pulling and straightening mechanism has the following advantages: the straightening clamp structure can straighten the element body before the equipment's pressing mechanism presses in the rubber cover, ensuring that the subsequent pressing and adding of the cover will not be skewed, thus avoiding pressure damage to the product; the action of the foot-pulling clamp clamping the element guide pin and the action of the equipment's pressing mechanism pressing in the rubber cover can be performed synchronously, thus improving the assembly efficiency; during the foot-pulling process, the rubber cover will be supported by the foot-pulling middle mold, so that the force points during the equipment's pressing mechanism pressing in the rubber cover are dispersed to the foot-pulling action, which ensures that there will be no skewed pressing and disperses the force during forced pressing, thus effectively ensuring the quality of element assembly, reducing material waste and saving product production costs.

[0004] However, the anode pin and cathode pin of the capacitor element may be deformed during processing, such as bending and rotation, which may lead to inconsistent thickness of the anode pin and cathode pin. When pulling the pin, due to the inconsistent thickness of the anode pin and cathode pin, the pin clamp can only clamp the thicker element pin, but not the thinner element pin. The pulling force only acts on one element pin, resulting in excessive pulling force on the element pin, which may cause the element pin to break. Utility Model Content

[0028] Embodiment 1

[0029] like Figure 1 and 2 As shown, a component pin straightening mechanism is used to straighten the capacitor element 100 and straighten the anode pin 110 and the cathode pin 130 on the capacitor element 100 before the assembly machine presses the rubber cover onto the capacitor element 100, so as to avoid the anode pin 110 and the cathode pin 130 of the capacitor element 100 being damaged and deformed due to the tilt of the capacitor element 100 when the rubber cover is pressed.

[0030] The element foot-pulling and straightening mechanism comprises a straightening device 200 and a foot-pulling device 300 . The straightening device 200 comprises a straightening clamp 210 . The foot-pulling device 300 comprises a foot-pulling clamp 310 . The foot-pulling clamp 310 is located above the straightening clamp 210 .

[0031] When in use, the element foot-pulling and straightening mechanism is arranged beside the element disc of the assembly machine. The element disc feeds the capacitor element 100 into the straightening clamp 210 by rotation, so the feeding direction of the straightening clamp 210 should be tangent to the circumference of the element disc. When the element disc feeds the capacitor element 100 into the straightening clamp 210, the feeding clamp on the element disc is located between the straightening clamp 210 and the foot-pulling clamp 310. The straightening clamp 210 first clamps the delivered capacitor element 100 to straighten the direction of the capacitor element 100 in cooperation with the feeding clamp. The two clamping positions of the straightening clamp 210 and the feeding clamp on the capacitor element 100 can determine the axial direction of the capacitor element 100 after straightening; then the foot-pulling clamp 310 clamps and straightens the anode pin 110 and the cathode pin 120 on the capacitor element 100.

[0032] Preferably, the clamping direction of the straightening clamp 210 is perpendicular to the clamping direction of the feeding clamp.

[0033] like Figure 3 and 4As shown, the foot-pulling clamp 310 includes a first foot-pulling clamp 311, a second foot-pulling clamp 312 and an opening and closing driving component 313, and the opening and closing driving component 313 is connected to drive the first foot-pulling clamp 311 and the second foot-pulling clamp 312 to open and close relative to each other; the second foot-pulling clamp 312 includes a clamp slide 3121, a first clamp slider 3124, a second clamp slider 3125, a first elastic member 3126 and a second elastic member 3127, and the first clamp slider 3124 and the second clamp slider 3125 are arranged on the clamp slider 3121. The first clamping jaw slider 3124 and the second clamping jaw slider 3125 can slide on the clamping jaw slide 3121 to approach or move away from the first foot-pulling clamp 311. The first clamping jaw slider 3124 and the second clamping jaw slider 3125 are respectively connected to the clamping jaw slide 3121 through the first elastic member 3126 and the second elastic member 3127. The first clamping jaw slider 3124 and the second clamping jaw slider 3125 slide close to the first foot-pulling clamp 311 under the elastic force of the first elastic member 3126 and the second elastic member 3127.

[0034] The element foot-pull straightening mechanism of the utility model sets the second foot-pull clamping claw 312 of the foot-pull clamp 310 as a first clamping claw slider 3124 and a second clamping claw slider 3125 which are separated from each other, wherein the first clamping claw slider 3124 corresponds to the anode pin 110 of the capacitor element 100, and is used to cooperate with the first foot-pull clamping claw 311 to clamp the anode pin 110 of the capacitor element 100, and the second clamping claw slider 3125 corresponds to the cathode pin 120 of the capacitor element 100, and is used to cooperate with the first foot-pull clamping claw 311 to clamp the cathode pin 120 of the capacitor element 100; when the opening and closing drive component 313 drives the first foot-pull clamping claw 311 and the second foot-pull clamping claw 312 to close relative to each other, the anode pin 110 and the cathode pin 110 of the capacitor element 100 are clamped together. When the pole pins 120 are clamped at the same time, if the anode pin 110 and the cathode pin 120 have different thicknesses due to deformation such as bending and rotation, the distances between the first clamping jaw slide 3124 and the second clamping jaw slide 3125 and the first pulling foot clamp 311 will be different to adapt to the clamping of anode pins 110 and cathode pins 120 of different thicknesses, and the first clamping jaw slide 3124 and the second clamping jaw slide 3125 are respectively connected to the clamping jaw slide 3121 through the first elastic member 3126 and the second elastic member 3127. Under the elastic force of the first elastic member 3126 and the second elastic member 3127, the first clamping jaw slide 3124 and the second clamping jaw slide 3125 can ensure that the anode pin 110 and the cathode pin 120 are clamped respectively.

[0035] In this embodiment, the first elastic member 3126 and the second elastic member 3127 can be, but are not limited to, springs.

[0036] The foot-pulling device 300 further includes a foot-pulling driving assembly 320 , and the foot-pulling driving assembly 320 is connected to the foot-pulling driving assembly 320 that drives the foot-pulling clamp 310 to move up and down.

[0037] After the straightening clamp 210 is closed to straighten the direction of the capacitor element 100, the foot-pull driving assembly 320 drives the foot-pull clamp 310 to descend so that the anode pin 110 and the cathode pin 120 of the capacitor element 100 enter the clamping range of the foot-pull clamp 310. After the foot-pull clamp 310 is closed to clamp the anode pin 110 and the cathode pin 120 at the same time, the foot-pull driving assembly 320 drives the foot-pull clamp 310 to rise to a predetermined height so that the foot-pull clamp 310 straightens the anode pin 110 and the cathode pin 120. After the foot-pull clamp 310 is opened to release the anode pin 110 and the cathode pin 120 at the same time, the foot-pull driving assembly 320 drives the foot-pull clamp 310 to rise and reset.

[0038] like Figure 5 As shown, the first foot-pulling clamp 311 includes a clamping head 3111, a first connecting portion 3112 and a first driving portion 3113, the clamping head 3111 is arranged at one end of the first connecting portion 3112, and the first driving portion 3113 is arranged at the other end of the first connecting portion 3112; the second foot-pulling clamp 312 also includes a second connecting portion 3122 and a second driving portion 3123, the clamping jaw slide 3121 is arranged at one end of the first connecting portion 3112, and the second driving portion 3123 is arranged at the other end of the second connecting portion 3122; the opening and closing drive assembly 313 includes an opening and closing slide 3131, an opening and closing slider 3132 and an opening and closing driver (not shown in the figure), the opening and closing slider 3132 is arranged on the opening and closing slide 3131, the opening and closing slider 3132 can slide and rise and fall on the opening and closing slide 3131, and the opening and closing driver is connected to the drive The opening and closing slider 3132 slides and rises and falls on the opening and closing slider 3131; the first connecting portion 3112 of the first foot-pulling clamp 311 is rotatably connected to the opening and closing slider 3131, and the first driving portion 3113 of the first foot-pulling clamp 311 is located outside one side of the opening and closing slider 3132; the second connecting portion 3122 of the second foot-pulling clamp 312 is rotatably connected to the opening and closing slider 3131, and the second driving portion 3123 of the second foot-pulling clamp 312 is located outside the other side of the opening and closing slider 3132; the opening and closing slider 3132 is respectively provided with gradient portions 3134 on both sides facing the first driving portion 3113 and the second driving portion 3123, and the size of the gradient portion 3134 gradually increases from bottom to top, and the gradient portion 3134 abuts against the first driving portion 3113 and the second driving portion 3123 respectively when the opening and closing slider 3132 slides down.

[0039] Since the opening and closing slider 3132 is respectively provided with a gradient portion 3134 on both sides facing the first driving portion 3113 and the second driving portion 3123, the size of the gradient portion 3134 gradually increases from bottom to top. When the opening and closing slider 3132 is raised to the highest point relative to the opening and closing slide seat 3131, the gradient portion 3134 is not in contact with the first driving portion 3113 and the second driving portion 3123. In the process of the opening and closing slider 3132 descending relative to the opening and closing slide seat 3131, the gradient portion 3134 first abuts against the first driving portion 3113 and the second driving portion 3123 respectively, and then the first driving portion 3113 and the second driving portion 3123 are abutted against each other. A driving part 3113 and a second driving part 3123 are pushed toward both sides respectively, and the distance between the first driving part 3113 and the second driving part 3123 gradually increases, so that the first foot-pulling clamp 311 and the second foot-pulling clamp 312 swing relative to each other, and the distance between the clamping head 3111 of the first foot-pulling clamp 311 and the clamping jaw slide 3121 of the second foot-pulling clamp 312 gradually decreases, and finally the clamping head 3111 and the clamping jaw slide 3121 are relatively closed, and then cooperate with the first clamping jaw slide 3124 and the second clamping jaw slide 3125 to clamp the anode pin 110 and the cathode pin 120 respectively.

[0040] A first abutting wheel 314 is disposed on the first driving portion 3113 of the first foot-pulling clamp 311 , and a second abutting wheel 315 is disposed on the second driving portion 3123 of the second foot-pulling clamp 312 .

[0041] Preferably, the first abutment wheel 314 and the second abutment wheel 315 are silicone wheels or rubber wheels.

[0042] A restoring elastic member 316 is further connected between the first foot-pulling clamping jaw 311 and the second foot-pulling clamping jaw 312 .

[0043] When the opening and closing slider 3132 is raised to the highest point relative to the opening and closing slider 3131, the gradient portion 3134 is not in contact with the first driving portion 3113 and the second driving portion 3123, and the opening and closing driving component 313 has no driving force on the first foot-pulling jaw 311 and the second foot-pulling jaw 312. The first foot-pulling jaw 311 and the second foot-pulling jaw 312 swing relative to each other under the elastic force of the reset elastic member 316, and the clamping head 3111 is relatively opened with the clamping jaw slide 3121, and then cooperates with the first clamping jaw slider 3124 and the second clamping jaw slider 3125 to respectively release the anode pin 110 and the cathode pin 120.

[0044] In this embodiment, the resetting elastic member 316 may be, but is not limited to, a spring.
