Description

TECHNICAL FIELD

[0001] The application discloses a capacitor pin shaping device and belongs to the technical field of electronic component processing devices. BACKGROUND

[0002] A capacitor is an element for storing electric quantity and electric energy (potential energy). A conductor is surrounded by another conductor, or an electric field line emitted by a conductor is all terminated on a conductor system of another conductor, which is called a capacitor. With the rapid development of electronic information technology, the update speed of digital electronic products is getting faster and faster. The production and sales of consumer electronic products, mainly flat panel televisions (LCD and PDP), notebook computers, digital cameras and other products, are continuously increasing. In particular, integrated circuits are widely used, thereby driving the growth of the capacitor industry.

[0003] The structure of the capacitor includes a container and two pins (i.e. an anode lead and a cathode lead). In order to mount the capacitor on a circuit board, the spacing between the two pins has specific requirements. After the pins pass through the through holes on the circuit board, the circuit on the circuit board is welded with the pins by using tin soldering. In the actual production process of the capacitor, in order to ensure smooth production, the two pins usually have a large margin. In addition, due to the small diameter of the pins, the pins are easily bent. In this way, the opening of the end of the pin far away from the capacitor is large. In the process of assembling the circuit board, the pin cannot be inserted into the through hole on the circuit board, and because the pin has a margin, in order to control the height of the capacitor protruding on the circuit board, the length of the pin protruding from the back of the circuit board is too large. Tin soldering cannot completely cover the pin, so that the pin needs to be trimmed again after welding. This not only is troublesome to operate, but also easily damages other electronic components.

[0027] The annular frame 2 is arranged outside the fixed seat 5, and the annular frame 2 is provided with a processing mechanism for shaping the capacitor 19 and a vibrating disc 1, and the processing mechanism and the vibrating disc 1 are symmetrically arranged with three in the center of the fixed seat 5, the processing mechanism mainly consists of an automatic feeding device 8, a rolling device 9, a first turnover device 10, a cutting device 11, a second turnover device 12 and an automatic discharging device 13, and the six devices are arranged one by one with the elastic clamp 7, the first cylinder 4 is arranged corresponding to the automatic feeding device 8, the first turnover device 10, the second turnover device 12 and the automatic discharging device 13, the vibrating disc 1 is arranged corresponding to the automatic feeding device 8, the automatic feeding device 8 can grab and send the capacitor 19 arranged in the vibrating disc 1 one by one into the elastic clamp 7, and the head of the capacitor 19 is clamped by the upper clamp block 28 and the lower clamp block 30, while the pin is exposed outside, the rolling device 9 can horizontally roll the exposed pin of the capacitor 19, the first turnover device 10 can first press the pin horizontally in the vertical direction, then release the head of the capacitor 19, the two pressing blocks 50 clamp the pin and rotate 90° as a whole, so that the two pins change from the vertical state to the horizontal state, to facilitate the cutting device 11 to cut the flattened pin, so that the length of the cut pin just meets the assembly requirement, after the capacitor 19 is successfully assembled on the circuit board, the length of the pin protruding from the back of the circuit board can be covered by soldering, so that the pin does not need to be cut again, and the two cut pins are rotated 90° from the horizontal state to the vertical state by the second turnover device 12, to facilitate the automatic discharging device 13 to send the capacitor 19 from the elastic clamp 7 to the external conveying frame.

[0028] In the embodiment, the automatic feeding device 8 is composed of a mounting frame 16, a first pneumatic clamp jaw 21, a rotating block 22, a sliding plate 23, a second pneumatic cylinder 18, a swing rod 25 and a rotating shaft 20. The mounting frame 16 is fixed on the annular frame 2, and the mounting frame 16 is provided with a guide sliding groove 14 having an inclined slide 15 and two horizontal slides 17 of different heights, the inclined slide 15 connecting the two horizontal slides 17. The mounting frame 16 is provided with a sliding rail, the sliding plate 23 being slidingly connected with the sliding rail, and the rotating shaft 20 being rotatably installed on the sliding plate 23, the two ends of the rotating shaft 20 being connected with the rotating block 22 and the swing rod 25 respectively. The first pneumatic clamp jaw 21 is fixed on the rotating block 22, and the other end of the swing rod 25 is provided with a pulley 24 located in the guide sliding groove 14 and capable of rotating the rotating shaft 20 by 90° when sliding between the two horizontal slides 17. The second pneumatic cylinder 18 is fixedly connected with the sliding plate 23. The first pneumatic clamp jaw 21 is in a horizontal state when close to the vibrating disc 1, so as to clamp two pins conveyed in a row, and the first pneumatic clamp jaw 21 is in a vertical state when close to the elastic clamp 7, so that the head of the capacitor 19 is close to the elastic clamp 7 and kept in a horizontal state with the pins, so as to be smoothly clamped by the upper clamp block 28 and the lower clamp block 30. The direction change of the first pneumatic clamp jaw 21 is controlled by the swing rod 25. The second pneumatic cylinder 18 can push the sliding plate 23 to slide along the sliding rail, so that the pulley 24 at one end of the swing rod 25 slides in the guide sliding groove 14, passes through the inclined slide 15 from one horizontal slide 17 to the other horizontal slide 17, so that the swing rod 25 rotates by 90° in the process, and the rotating shaft 20 drives the rotating block 22 to synchronously rotate by 90°, so as to change the state of the first pneumatic clamp jaw 21 and grasp the capacitors 19 one by one and then send them into the elastic clamp 7, so as to complete the automatic feeding action.

[0029] When the elastic clamp 7 clamps the capacitor 19, the rotating disc 3 driven by the cam divider rotates 20° to reach the position corresponding to the rolling device 9. Since the pins of the capacitor 19 are deformed to a greater extent away from the head than close to the head during production and assembly, when the opening width of the pin is large and there is bending deformation, it will cause the pin to be unable to be inserted into the through hole of the circuit board, so it is necessary to flatten the pin. The rolling device 9 is correspondingly arranged on one side of the first turnover device 10, and the rolling device 9 comprises a third cylinder 37, a pressure bearing table 35 and two rolling shafts 34. The pressure bearing table 35 is provided with a mounting block 44, and the two rolling shafts 34 are located on both sides of the pressure bearing table 35 and are respectively connected with the mounting block 44 in a sliding manner. Drive pieces 33 for controlling the distance between the two rolling shafts 34 are arranged on both sides of the pressure bearing table 35. The third cylinder 37 is fixedly connected with the pressure bearing table 35. The drive piece 33 comprises a sliding block 38, a movable block 58, a plug rod 43 and a second spring 41. The movable block 58 is connected with both ends of the rolling shaft 34. One end of the plug rod 43 is fixedly connected with the movable block 58, and the other end penetrates through the mounting block 44. The second spring 41 is sleeved on the outer side of the plug rod 43, and both ends are respectively abutted on the mounting block 44 and the movable block 58. Two sliding blocks 38 are symmetrically arranged on both sides of the pressure bearing table 35, and the two sliding blocks 38 are connected through a fixed shaft 39. A sliding groove for the sliding of the fixed shaft 39 is arranged in the pressure bearing table 35. One end of the sliding block 38 close to the rolling shaft 34 has a protruding portion 40, and the height of the protruding portion 40 is less than the height of the sliding block 38. A push block 42 for pushing the sliding block 38 to slide is arranged on the elastic clamp 7. A stop block 36 is arranged on the side surface of the cylinder body of the third cylinder 37. When the third cylinder 37 drives the pressure bearing table 35 to move towards the elastic clamp 7, the lower end of the movable block 58 abuts against the sliding block 38. In order to make the sliding smooth, the lower end of the movable block 58 is in a semi-cylindrical structure. At this time, the distance between the two rolling shafts 34 and the pressure bearing table 35 is large, and the end of the pressure bearing table 35 is arranged in an inclined manner, so that the two pins can be smoothly inserted between the rolling shaft 34 and the pressure bearing table 35. When the pressure bearing table 35 is about to touch the elastic clamp 7, the push block 42 first abuts against the protruding portion 40 on the sliding block 38, so that the sliding block 38 remains stationary, and the pressure bearing table 35 continues to move. At this time, the movable block 58 and the sliding block 38 slide relative to each other, and slide from the side surface of the sliding block 38 to the protruding portion 40. Under the action of the second spring 41, the movable block 58 drives the rolling shaft 34 to press the pin. Then the third cylinder 37 drives the pressure bearing table 35 to reset. At this time, the rolling shaft 34 horizontally presses the pin on the pressure bearing table 35 in a rotating manner. Thus, the pin can be flattened in a horizontal plane. After the sliding block 38 abuts against the stop block 36, the sliding block 38 slides forward, so that the movable block 58 slides from the protruding portion 40 to the side surface of the sliding block 38. In this way, the movable block 58 can drive the rolling shaft 34 to move away from the pressure bearing table 35, so as to prepare for rolling the pins of the next capacitor 19.

[0031] The cutting device 11 is composed of a second mounting base 53, an upper cutting seat 55 and a lower cutting seat 54, the second mounting base 53 is provided with a fourth pneumatic cylinder 56 for driving the vertical movement of the upper cutting seat 55 and the lower cutting seat 54 respectively, the side surface of the lower cutting seat 54 is fixedly connected with a material receiving plate 57, one end of the material receiving plate 57 is inclined downward through the second mounting base 53, and the annular frame 2 is provided with a waste box 6 below the material receiving plate 57, when the capacitor 19 subjected to the twice flattening treatment is moved to the corresponding position of the cutting device 11 by the rotating disc 3, the pins are located between the upper cutting seat 55 and the lower cutting seat 54, at this time, the upper cutting seat 55 and the lower cutting seat 54 are driven by the two fourth pneumatic cylinders 56 to cut the pins to a fixed length, the material receiving plate 57 moves synchronously with the lower cutting seat 54, so that the waste generated by cutting is automatically dropped into the waste box 6, so as to keep the surface of the annular frame 2 clean.

[0032] After the pin cutting of the capacitor 19 is completed, the two horizontal state pins are clamped and turned to the vertical state by the subsequent second turnover device 12, and the second turnover device 12 is the same as the first turnover device 10, and the action principle is not repeated, and the pin will be flattened three times before turning to reduce the bending deformation of the end of the pin cutting, and the automatic discharge device 13 is the same as the automatic feeding device 8, which can clamp and send the capacitor 19 after shaping from the elastic clamp 7 to the external conveying frame, so that the automatic shaping process of the capacitor 19 can be realized, the three processing mechanisms work synchronously, and there is time overlap between each process, thereby greatly saving the waiting time, effectively improving the processing efficiency of the capacitor 19, and making the pin meet the assembly needs of the circuit board well.
