Description

Technical Field

[0001] The present application relates to the field of terminal processing equipment, and in particular to a cam pin device. Background Art

[0002] In the electronics manufacturing sector, the increasing diversification and miniaturization of electronic products are driving the demand for precision and efficiency in the assembly of electronic components. This is particularly true of pin insertion, a critical step in ensuring stable electrical connections and accurate signal transmission in electronic devices. Efficient and precise pin insertion technology improves product quality and production efficiency, reduces costs, and thus enhances a company's market competitiveness. Advances in electronic pin insertion technology are also driving the development of smaller, thinner, and more powerful electronic devices, fostering progress across the electronics industry.

[0003] The related art discloses a cam mechanism for automatic pin insertion, which includes a fixed base, a carrier, a carrier plate, a gantry, a cutting guide frame, a feeding assembly, a conveying track, a pin chuck assembly, a cutting knife bar, a transmission shaft, and multiple cams and drive rods. The fixed base serves as a supporting base, and a carrier is mounted on its upper surface, and a carrier plate is mounted in a notch on the side of the carrier. The transmission shaft is rotatably mounted inside the carrier, and a driving assembly is mounted on the outside to drive the transmission shaft to rotate. The first cam, the second cam, and the third cam are sequentially mounted on the outside of the transmission shaft. The carrier plate is fixed in the notch of the carrier, and a gantry, a cutting guide frame, a feeding assembly, and a conveying track are fixed on its upper surface. The pin chuck assembly is also slidably arranged. The pin chuck assembly and the cutting guide frame are distributed side by side at the conveying tail end of the conveying track, and the feeding assembly is located at the conveying starting end of the conveying track. The second and third drive rods are pivotally mounted within the gantry. The outer end of the second drive rod is hinged to the pin chuck assembly, driving it to clamp the conductive material strip. The outer end of the third drive rod is hinged to the upper end of the cutting bar, forcing the bar to slide downward and cut the conductive material strip. A cutting guide frame is fixed to the upper surface of the carrier plate. Its upper surface features a bar guide groove, and a vertical cutting bar is slidably mounted within it. The cutting bar has a cutting blade on its underside. The feed assembly, located at the initial end of the conveyor track, drives the conductive material strip within the track.

[0004] While this system achieves automated conveying, clamping, cutting, and insertion of conductive tape, the insertion process relies heavily on mechanical transmission via a cam and drive lever, making it less adaptable to the insertion requirements of components of varying specifications. Furthermore, the accuracy of pin placement is limited by the precision and stability of the mechanical transmission. Especially during high-speed insertion, mechanical vibration and shock can cause pin position deviation, impacting insertion quality and production efficiency. Summary of the Invention

[0005] In order to solve the above technical problems, the present application provides a cam pin device.

[0006] The present application provides a cam pin device that adopts the following technical solution: A cam pin device comprises a base, a sliding seat, a first driving mechanism, a material belt conveying mechanism, a pressing and pushing mechanism, a pushing mechanism, a second driving mechanism and a cutting mechanism; the sliding seat is slidably matched with the base, the first driving mechanism is arranged on the base, and the first driving mechanism is used to drive the sliding seat to move in the horizontal direction; the material belt conveying mechanism is arranged on the sliding seat, and the material belt conveying mechanism is used to move in the horizontal direction; the cutting mechanism is arranged on the sliding seat, and the cutting mechanism is used to cut the terminal row to form terminals; the pushing mechanism is slidably matched with the sliding seat, the second driving mechanism is arranged on the sliding seat, and the second driving mechanism is used to drive the pushing mechanism to move in the horizontal direction; the pushing mechanism pushes the pressing and pushing mechanism toward the direction close to the component when moving; the pressing and pushing mechanism is used to insert the terminal into the component.

[0007] By adopting the above-mentioned technical solution, the cam pin insertion device utilizes a first drive mechanism to drive the sliding seat to move horizontally through the sliding cooperation of the base and the sliding seat, so that the material strip conveying mechanism can horizontally convey the conductive needle material strip; at the same time, the cutting mechanism is arranged on the sliding seat to cut the terminal row to form a terminal; the pushing mechanism slides with the sliding seat, and under the action of the second drive mechanism, the pressing and pushing mechanism moves toward the component, thereby inserting the terminal into the component. Compared with the background technology that relies on the mechanical transmission of cams and drive rods to achieve pin insertion and has poor adaptability and limited accuracy, this device can achieve pin insertion more flexibly through the coordinated action of multiple mechanisms, is more adaptable to the pin insertion requirements of components of different specifications, and reduces the problem of pin position offset caused by mechanical vibration and impact, which is conducive to improving pin insertion quality and production efficiency.

[0008] Optionally, the first driving mechanism includes a first screw rod, a first motor and two first supports; the two first supports are fixed on the base, and the two ends of the first screw rod are rotatably connected to the two first supports respectively; the first screw rod passes through the sliding seat, and the first screw rod is threadedly engaged with the sliding seat; the first motor is fixed on the base, and the output shaft of the first motor is fixedly connected to the end of the first screw rod.

[0009] By adopting the above technical solution, the two first supports are fixed on the base to provide stable support for the first screw rod, so that the two ends of the first screw rod are rotatably connected to the two first supports respectively, to ensure that the first screw rod can rotate freely; the first screw rod passes through the sliding seat and is threadedly matched with it. When the first motor is fixed on the base and its output shaft is fixedly connected to the end of the first screw rod, the operation of the first motor drives the first screw rod to rotate. Due to the threaded matching relationship between the sliding seat and the first screw rod, the rotational motion of the first screw rod is converted into linear motion of the sliding seat, thereby driving the sliding seat to move precisely in the horizontal direction. This driving method through the matching of the screw rod and the motor has a simple structure and smooth transmission, can achieve precise control of the moving distance and speed of the sliding seat, provides a basis for the precise operation of subsequent components such as the material belt conveying mechanism, and helps to improve the working accuracy and stability of the entire cam pin device.

Since the eccentric protrusion is fixed at the eccentric position of the first eccentric wheel and is located in the driving groove of the lifting seat and slides with it, when the first eccentric wheel rotates, the eccentric protrusion will slide in the driving groove, thereby driving the lifting seat to slide on the first support seat to realize the reciprocating motion of the lifting seat; at the same time, the sliding block slides with the lifting seat and the moving direction is the first direction, and one end of the sliding block is fixedly connected to the end of the pusher rod. When the pushing mechanism pushes the pressing and pushing mechanism to move towards the component, combined with the reciprocating motion of the lifting seat, the pusher rod can also have a specific lifting action during the horizontal movement, and the eccentric wheel principle is used to realize a complex and precise motion trajectory of the pusher rod, which helps to more accurately insert the terminal into the component and improve the accuracy and reliability of the pin.

The first spring generates an elastic force, which will continuously and steadily act on the pressing and pushing mechanism, so that it can move in the direction close to the component with appropriate force. This method of using spring buffering and force application can not only ensure that the pressing and pushing mechanism has sufficient power to insert the terminal into the component, but also avoid excessive or unstable force caused by rigid pushing, reduce damage to components and terminals, improve the smoothness and quality of the pin insertion process, and at the same time, the elasticity of the spring can also adapt to slight dimensional deviations and position changes during the pin insertion process to a certain extent, thereby enhancing the adaptability and reliability of the device.

When the third motor 72 is started, the output shaft of the third motor 72 drives the first eccentric wheel 73 to rotate. Since the eccentric protrusion 74 is located at an eccentric position of the first eccentric wheel 73, the rotation of the first eccentric wheel 73 causes the eccentric protrusion 74 to slide within the drive groove, thereby driving the lifting seat 75 to rise and fall. The sliding block 76 slides with the lifting seat 75. The sliding block 76 moves in a first direction. The end of the sliding block 76 facing the cutting mechanism is fixedly connected to the end of the push rod 77. The push rod 77 is generally in the shape of a slender rod.

[0048] Reference Figure 4 Two second guide rails 711 are fixedly mounted on the sidewall of the first support base 71 near the lifting base 75. The second guide rails 711 extend vertically. Two second sliders 751 are fixedly mounted on the sidewall of the lifting base 75 near the first support base 71. The second guide rails 711 correspond to each second slider 751 one by one. Each second slider 751 slidably engages with a second guide rail 711, enhancing the stability of the lifting base 75 during its ascent and descent.

[0049] Reference Figure 3 and Figure 6 A pushing groove 771 is provided on the lower surface of the end of the pushing rod 77 facing the cutting mechanism, and the length direction of the pushing groove 771 extends along the first direction. The pushing groove 771 is open at the end facing the cutting mechanism, and closed at the end away from the cutting mechanism. The pushing groove 771 adopts a non-slip inner wall and an elastic buffer layer to ensure that the pin can stay stably in the specified position after cutting, avoiding position deviation due to vibration or collision, and providing precise protection for subsequent pin insertion operations. The cut pin falls accurately into the pushing groove 771 of the pressing push rod. The special structure of the pushing groove 771 (such as the V-groove surface and the elastic buffer layer) can ensure that the pin is positioned after cutting, avoid secondary deviation, and improve the efficiency of pin insertion.

[0050] Reference Figure 8 and Figure 9 Specifically, the cutting mechanism includes a cutting drive assembly 8 and a cutting assembly 9. The cutting drive assembly 8 includes a second support seat 81, a fourth motor 82 and a second eccentric wheel 83. The second support seat 81 is fixed to the upper surface of the first sliding plate 21, and the second eccentric wheel 83 is rotatably connected to the second support seat 81. The fourth motor 82 is fixed to the second support seat 81, and the output shaft of the fourth motor 82 passes through the second support seat 81 and is rotatably connected to the second support seat 81. An eccentric hole 84 is provided on the second eccentric wheel 83, and the eccentric hole 84 is located at an eccentric position of the second eccentric wheel 83. The output shaft of the fourth motor 82 passes through the eccentric hole 84, and the second eccentric wheel 83 is fixedly connected to the output shaft of the fourth motor 82.

[0051] Reference Figure 7 、 Figure 8 and Figure 9 The cutting assembly 9 includes a drive seat 91, a first lifting block 92, a second lifting block 93, a second spring 94, a second guide seat 95, a third spring 96, and a cutter 97. A rotating hole 911 is provided at the center of the drive seat 91. The second eccentric wheel 83 is inserted into the rotating hole 911. The drive seat 91 is rotatably connected to the second eccentric wheel 83. At the same time, the top of the first lifting block 92 is rotatably connected to the drive seat 91. The second guide seat 95 is fixed to the side wall of the second support seat 81. A first lifting slot 951 is provided on the second guide seat 95. The first lifting slot 951 extends in the vertical direction, and both ends of the first lifting slot 951 are open. The first lifting block 92 and the second lifting block 93 are both located in the first lifting slot 951. The first lifting block 92 and the second lifting block 93 are both slidably engaged with the first lifting slot 951. The first lifting block 92 and the second lifting block 93 are slidably engaged with each other.

[0052] Reference Figure 8 and Figure 9Specifically, a sliding groove 921 is defined on one side of the first lifting block 92, and the second lifting block 93 includes a sliding portion 931 and a pressing portion 932. The sliding portion 931 slides in engagement with the sliding groove 921. Furthermore, a positioning groove 933 is defined on the sliding portion 931, and the pressing portion 932 is mounted within the positioning groove 933. The pressing portion 932 is fixedly connected to the sliding portion 931 via bolts, making it easier for workers to install and remove the pressing portion.

[0053] In this embodiment, there are two second springs 94, and both second springs 94 are located between the sliding groove 921 and the sliding portion 931. The top end of the second spring 94 is fixedly connected to the inner wall of the top end of the sliding groove 921, and the bottom end of the second spring 94 is fixedly connected to the top end of the sliding portion 931.

[0054] Reference Figure 8 In this embodiment, there are four third springs 96, each of which is located between the first lifting block 92 and the pressing portion 932. Each third spring 96 extends vertically, with the bottom end of each third spring 96 fixedly connected to the pressing portion 932, and the top end of each third spring 96 abutting the bottom end of the first lifting block 92.

[0055] During the cutting process, the pressing portion 932 is used to press the terminal strip together. The terminal strip includes multiple terminals, with adjacent terminals connected by a connecting portion. The bottom end of the pressing portion 932 is integrally formed with multiple sets of positioning assemblies, which are spaced apart along the second direction. Each set of positioning assemblies includes two positioning portions 935, which are spaced apart along the first direction and are used to position the ends of the terminals.

[0056] Reference Figure 8 and Figure 9 In this embodiment, there are two cutters 97 , both extending vertically. The top of each cutter 97 is fixedly connected to the bottom of the first lifting block 92 . The pressing portion 932 includes two guide holes 934 , extending vertically and open at both ends. Each cutter 97 corresponds to a guide hole 934 , with each cutter 97 inserted into and slidingly engaged with the guide hole 934 to sever the connection between two terminals.

[0057] When the fourth motor 82 is started, the output shaft drives the second eccentric wheel 83 to rotate. Due to the eccentric setting of the second eccentric wheel 83, the drive seat 91 performs non-linear motion, thereby driving the first lifting block 92 and the second lifting block 93 to move up and down in the first lifting slot 951. During the movement, the second spring 94 plays a buffering and reset role to ensure the smoothness of the movement. The first lifting block 92 drives the second lifting block 93 and the cutter 97 to move downward. During the descent of the second lifting block 93, when the pressing part 932 is pressed on the terminal strip, the pressing part 932 has a pressing and fixing effect on the terminal strip. The positioning part 935 first positions the two ends of the terminal, and then the cutter 97 continues to cut the material strip between the two terminals downward, thereby completing the cutting action and achieving precise cutting of the terminal material strip.

[0058] The implementation principle of this embodiment is as follows: the base 1 serves as the supporting foundation of the entire device and provides a track for the horizontal movement of the sliding seat 2. The first driving mechanism 3 drives the sliding seat 2 to move to the appropriate position on the base 1 according to the different thicknesses of the components. The second driving mechanism 6 drives the pushing seat 51 to move further on the sliding seat 2, so that the pressing push rod is accurately positioned above the pin on the two-dimensional plane. The pressing push mechanism 7 drives the lifting seat 75 to descend, driving the pressing push rod to descend, and pressing and fixing the pin. At this time, the cutting drive assembly 8 of the cutting mechanism drives the lifting block to descend, and the pressing block first presses the material strip, and then the cutter 97 descends to cut the material strip to form a single pin. The cut pin is located in the pushing groove 771 of the pressing push rod, and the pushing groove 771 ensures the accurate position of the pin. When the pin needs to be inserted into the component, the sliding seat 2 remains stationary, and the pushing seat 51 continues to move forward to accurately insert the pin into the pin hole of the component. It effectively improves the precision and efficiency of electronic pin insertion, adapts to the pin insertion requirements of components of different specifications, and overcomes the problems of low efficiency, poor precision, and poor versatility in traditional pin insertion processes.
