Description

Technical Field

[0001] The present invention relates to a bending device, in particular to a diode pin high-speed bending device. Background Art

[0002] During the production process of wire-wound resistors, there will be long pin wires at both ends. The pin wires at both ends and the wire-wound resistor are kept in a straight line. When the wire-wound resistor is installed on the circuit board, the straight pin wires at both ends need to be bent 90 degrees before the pin wires can be inserted into the circuit connection holes. Therefore, the pin wires of the wire-wound resistor often need to be bent in advance before use.

[0003] The basic principle of existing automatic bending devices is as follows Figure 1 As shown, support grooves are evenly spaced on the support rack, and the pins of the resistor are placed in the support grooves to lift the resistor. A feeding device is provided in the middle of the support rack, and a placement groove that can accommodate the resistor is provided on the feeding device. A lifting arm is provided above the feeding device, and telescopic gas rods are provided on both sides of the lifting arm, and a pressure plate is installed on the telescopic gas rod; specifically, the lifting arm moves down to press the resistor in the placement groove, and the pressure plate is pushed out by the telescopic gas rod to press the pins of the resistor to achieve bending. After the bending is completed, the feeding device first lifts the resistor and then moves forward a distance and then lowers it. Then the feeding device returns to its original position, thereby lifting the bent resistor to the front, and the resistor that has not been bent subsequently will be lifted to the bottom of the lifting arm to continue the bending operation. During the implementation of this bending technology, the bending speed of the resistor pins depends on the feeding speed of the feeding device. Since the feeding device needs to move at multiple angles, the resistor cannot be quickly moved on the support. Too fast a lifting action can easily cause the resistor to fall from the support. Therefore, due to the constraints of the feeding device, the speed of automatic bending of the resistor cannot be effectively and significantly improved. Summary of the Invention

DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. It will be understood that the specific embodiments described herein are only used to explain the present application, rather than to limit the present application. It should also be noted that, for ease of description, only some, rather than all, structures related to the present application are shown in the drawings. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0034] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections, electrical connections, or mutual communication; they can refer to direct connections or indirect connections through an intermediate medium; they can refer to internal communication between two components or the interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on specific circumstances.

[0035] The present invention specifically discloses a diode pin high-speed bending device, such as Figure 2-Figure 12 As shown, it includes: a support frame 11, a boom 12 is symmetrically installed on the upper part of the support frame 11, a conveyor belt 13 is fixedly installed on the support frame 11 directly below the boom 12, a dual-axis motor 14 is installed in the center between the two booms 12, an eccentric wheel 15 is rotatably installed on the boom 12, and the rotating shaft of the dual-axis motor 14 is connected to the eccentric wheel 15 to drive the eccentric wheel 15 to rotate; refer to Figure 4 and Figure 5 As shown, the movable frame 17 is slidably mounted on the boom 12. The movable frame 17 is located directly above the conveyor belt 13 and can slide up and down on the boom 12. Side panels 171 extending downward are provided on both sides of the movable frame 17. One end of the pull rod 16 is connected to the eccentric wheel 15, and the other end of the pull rod 16 is connected to the movable frame 17. Therefore, when the eccentric wheel 15 rotates, the movable frame 17 is pulled by the pull rod 16 to move back and forth in the up and down directions. When in use, after the resistor 505 is transmitted to the bottom of the movable frame 17 through the conveyor belt 13, the conveyor belt 13 stops driving. The dual-axis motor 14 drives the movable frame 17 to slide downward, thereby causing the side plate 171 to press the pins of the resistor 505 downward. When the side plate 171 is pressed down to the limit position, the pins will be bent. After the movable frame 17 is pulled up, the conveyor belt 13 continues to drive to transport the bent resistor 505 away, and the unbent resistor 505 is moved to the bottom of the movable frame 17. This intermittent alternation is carried out. As the frequency of the alternating cooperation between the movable frame 17 and the conveyor belt 13 increases, the bending speed will become faster and faster. Figure 4 As shown, a receiving plate 18 is installed on the side walls on both sides of the conveyor belt 13. When the resistor 505 is directly below the movable frame 17, the root position of the pin on the resistor 505 will also be placed on the receiving plate 18. Therefore, when the side plate 171 presses the pin downward, the pin will not bend from the root, but will bend from the edge position of the receiving plate 18.

[0036] The present invention places the resistor 505 on the conveyor belt 13 for transmission, and the dual-axis motor 14 drives the movable frame 17 to move up and down. During the rapid lifting and moving process, the movable frame 17 can use the side plate 171 to press and bend the pins of the resistor 505 located below. The resistor 505 only needs to be transported in a straight line during this process. As the lifting frequency of the movable frame 17 increases, the conveying speed of the resistor 505 can also be accelerated, thereby achieving a rapid bending effect.

[0037] Reference Figure 6 As shown, the surface of the belt body 131 of the conveyor belt 13 is provided with receiving grooves 132 at even intervals, and the resistor 505 is embedded in the surface of the belt body 131 through the receiving grooves 132. After the resistor 505 is embedded in the surface of the belt body 131, the high-frequency bending action performed on the resistor 505 will not cause the resistor 505 placed on the belt body 131 to be detached, thereby ensuring that the resistor 505 can be stably transported during the bending operation. Accordingly, the resistor 505 is input from one end of the conveyor belt 13, and an ejection component is provided at the end where the resistor 505 is sent out. The function of the ejection component is to eject the resistor 505 embedded in the surface of the belt body 131, thereby separating the bent resistor 505 from the belt body 131.

[0038] Reference Figure 6 As shown, a gap 133 is opened in the area between the two receiving grooves 132. Through the function of this gap 133, the two edges of each receiving groove 132 are independent of each other and not connected, that is, the resistor 505 embedded in the receiving groove 132 can be clamped by each independent receiving groove 132. When one of the receiving grooves 132 expands or contracts freely, it will not affect the clamping of the resistor 505 by the other receiving grooves 132, thereby achieving that each receiving groove 132 can independently apply a clamping force to the resistor 505.

[0039] Reference Figure 7 As shown, the ejection component includes: an intermediate groove 21 that is recessed for a full circle is opened on the inner circle of the belt body 131, and the depth of the intermediate groove 21 is connected to the receiving groove 132, so that a through opening 22 leading to the intermediate groove 21 is opened on the receiving groove 132, and a fixed ring 23 is provided in the area of the driving wheel 134 on one side of the conveyor belt 13. The fixed ring 23 does not rotate together with the driving wheel 134, and a portion of a raised edge 24 is provided on the fixed ring 23. The raised edge 24 can be embedded in the intermediate groove 21 and abut against the through opening 22.

[0040] Specifically, after the belt body 131 moves with the resistor 505 to the area where the driving wheel 134 is located, the belt body 131 bends and deforms. At the same time, the accommodating groove 132 in this area also opens due to the bending of the belt body 131. At this time, the resistor 505 in the accommodating groove 132 is no longer clamped. Therefore, after the resistor 505 contacts the raised edge 24 on the fixing ring 23, the raised edge 24 will push the resistor 505 out from the area where the middle groove 21 is connected to the through port 22, thereby causing the resistor 505 to detach from the belt body 131.

[0041] Reference Figures 8-10 As shown, an installation chamber 30 is opened in the middle of the conveyor belt 13, a first hydraulic push rod 31 is installed on the side wall of the conveyor belt 13, an elastic reset button 32 is provided on the first hydraulic push rod 31, and the elastic reset button 32 is used to enable the first hydraulic push rod 31 to automatically reset after being pressed, and the second hydraulic push rod 33 is provided in the installation chamber 30, and two guide blocks 35 are symmetrically provided in the installation chamber 30, and the receiving plates 18 on both sides are slidably provided on both sides of the guide blocks 35. The two sliding receiving plates 18 are connected together by a folding connecting rod 34 symmetrically arranged in the installation chamber 30. The folding connecting rod 34 is a three-section structure, and the two ends of the folding connecting rod 34 are connected to the receiving plates 18 on both sides, and the two ends of the second hydraulic push rod 33 are respectively connected to the middle part of the folding connecting rod 34 on both sides. Figure 10 As shown, when the second hydraulic push rod 33 is extended, the folding links 34 on both sides will be straightened, thereby pushing the receiving plate 18 out of the guide plate to move away from each other. When the second hydraulic push rod 33 is contracted, the middle parts of the folding links 34 on both sides will be pulled closer to each other, thereby pulling the receiving plate 18 closer to each other, and the corners of the top edge of the receiving plate 18 are arc chamfers.

[0042] Specifically, the fluid paths of the first hydraulic push rod 31 and the second hydraulic push rod 33 are connected to each other through pipes. Therefore, after pushing the first hydraulic push rod 31, the second hydraulic push rod 33 is pushed out. After the movable frame 17 brings the side plate 171 to press the pin of the resistor 505 downward, the pin is bent, and the movable frame 17 also presses the first hydraulic push rod 31 downward, thereby extending the second hydraulic push rod 33, and correspondingly pushing out the receiving plate 18. In the process of the receiving plate 18 sliding outward, the pin bending area will continue to migrate outward for a distance following the movement of the receiving plate 18. Thanks to the arc chamfer on the top of the receiving plate 18, the migration of the pin bending area is sliding along the arc chamfer, so it will not be stuck by the right-angled edge. As the movable frame 17 rises and no longer contacts the first hydraulic push rod 31, the first hydraulic push rod 31 is reset, and then the second hydraulic push rod 33 is reset, and finally the side plate 171 is retracted.

[0043] The effect is that when the pins are bent downward from the top of the receiving plate 18 along the corners, the bent pins on both sides will be tightly attached to the side walls of the receiving plate 18. When the conveyor belt 13 transports the bent resistor 505 out of the area, the tightly attached pins will rub against the receiving plate 18 during the movement and be deflected, thereby causing the pins that were originally vertically downward to tilt, which is not conducive to the subsequent step of cutting the pins. By expanding the receiving plate 18, the spacing between the bent pins can be enlarged to avoid frictional contact between the pins and the receiving plate 18.

[0044] Reference Figure 8 As shown, the upper guide plate 41 is installed on the edge of one side of the boom 12, and the lower guide plate 42 is installed on one side of the conveyor belt 13. The upper guide plate 41 and the lower guide plate 42 are on the same side, and the upper guide plate 41 and the lower guide plate 42 are parallel to each other. The upper guide plate 41 and the lower guide plate 42 are arranged at an angle toward the conveyor belt 13 as a whole, and a gap is left between the two to allow the resistor 505 to pass through to guide the resistor 505 to fall on the belt body 131. The gap becomes a feeding channel for the resistor 505 to lead to the belt body 131. The upper guide plate 41 is provided with a sinking portion 43 close to the belt body 131, so as to squeeze the resistor 505 through the sinking portion 43 and embed it into the accommodating groove 132.

[0045] Specifically, the resistor 505 slides down from the feeding channel and falls on the belt body 131 after sliding to the bottom. As the belt body 131 is transmitted, the resistor 505 falls into the receiving groove 132. Under the joint action of the sinking part 43 and the transmitted belt body 131, the sinking part 43 pushes the resistor 505 so that the resistor 505 is embedded in the receiving groove 132. As the belt body 131 is transmitted, the resistors 505 are inserted one by one from the feeding channel into the receiving groove 132 of the belt body 131.

[0046] Reference Figure 8 、 Figure 11 and Figure 12As shown, it also includes: a bottom plate 51 fixedly mounted on the side walls on both sides of the conveyor belt 13, the bottom plate 51 is located on the side of the conveyor belt 13 away from the upper guide plate 41, the bottom plate 51 is connected to a movable plate 52 by a hinge, a cutter 53 is slidably arranged on the movable plate 52, and slides to a specified position and remains fixed as needed, the blade of the cutter 53 faces one side of the bottom plate 51, the resistor 505 pins are bent vertically downward, and after being transported by the conveyor belt 13, the vertically downward pins will be between the bottom plate 51 and the cutter 53. At this time, only the movable plate 52 needs to be pressed to make the cutter 53 cut the pins. By adjusting the position of the cutter 53, the length of the cut pins will also be different, so it can be adjusted as needed; In order to better cooperate with the lifting and lowering action of the movable frame 17 to cut the pins, an extension arm 54 is fixedly installed on the movable plate 52, and the extension arm 54 extends toward the boom 12. A movable pressing piece is provided between the end part of the extension arm 54 and the boom 12. One end of the connecting piece 58 is connected to the movable pressing piece, and the other end is connected to the movable frame 17. As the movable frame 17 moves downward, the movable pressing piece pulls the extension arm 54 close to the boom 12, so that the cutter 53 can be pressed on the bottom plate 51 to cut off the pin. When the movable frame 17 moves upward, the movable pressing piece pushes the extension arm 54 away from the boom 12, thereby separating the cutter 53 and the bottom plate 51, so that the pin can enter between the cutter 53 and the bottom plate 51.

[0047] Reference Figure 11 and Figure 12 As shown, the movable pressing member includes: a fixed plate 55 fixedly mounted on the boom 12, an inclined guide groove 56 is opened on the fixed plate 55, one end of the slider 57 slides in the guide groove 56, and the other end is slidably connected to the extension arm 54. When the slider 57 slides downward along the guide groove 56, it pulls the extension arm 54 close to the boom 12, thereby pressing the cutter 53 on the bottom plate 51. When the slider 57 slides upward along the guide groove 56, the slider 57 pushes the extension arm 54 away from the boom 12, and one end of the connecting member 58 is connected to the slider 57, so that the movable frame 17 moves up and down. The slider 57 is moved up and down by means of the connecting member 58; wherein the slider 57 is slidably connected to the extension arm 54, so when the extension arm 54 is away from or close to the boom 12, the angle of the slider 57 is different. Therefore, in order to avoid getting stuck during the up and down movement of the connecting member 58 when connected to the movable frame 17, a rotating part 581 that can rotate is required on the connecting frame to be connected to the slider 57, so that when the connecting member 58 pulls the slider 57 up and down, the rotating part 581 can adaptively deflect while still maintaining the connection with the movable frame 17.

[0048] After the base plate 51, movable plate 52, cutter 53 and extension arm 54 cooperate with each other and are connected to the movable frame 17 through a movable pressing piece, each time the movable frame 17 moves downward, the cutter 53 can be pressed against the base plate 51, thereby cutting off the bent vertical resistor 505 pins, and the sliding adjustable position of the cutter 53 can control the length of the cut pins.

[0049] The above-described embodiments merely represent preferred embodiments of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications, improvements, and substitutions without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention.
