Abstract
Description
Technical Field
[0001] This invention relates to the field of lead wire adjustment technology, specifically to an automatic DIP lead wire shaping machine. Background Technology
[0002] Dual in-line package (DIP), also known as DIP packaging or DIL, is a type of integrated circuit packaging. The integrated circuit is rectangular in shape with two rows of parallel metal leads on both sides, called pin headers. DIP-packaged components can be soldered into plated through-holes on a printed circuit board or inserted into DIP sockets. During assembly, the integrated circuit board is transported using conveyor equipment, and then the leads are inserted into both sides of the integrated circuit board.
[0003] Currently, when DIP leads are inserted into integrated circuit boards, the leads are often bent or deformed. Direct insertion can cause short circuits or damage to the leads. Therefore, the leads need to be shaped. This shaping process requires using needle-nose pliers or tweezers. Before insertion, the pliers are held by hand, and the deformed parts of the leads are twisted and straightened using the jaws. However, since there are many leads in two rows, straightening each lead individually with needle-nose pliers is slow and affects the adjustment of other leads. Furthermore, the leads adjusted with needle-nose pliers may have different distributions after adjustment due to varying forces. To address this, we propose an automatic DIP lead shaping machine. Summary of the Invention
[0004] The purpose of this invention is to provide an automatic DIP lead shaping machine to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: an automatic DIP lead forming machine, comprising a forming transport frame and a robotic arm. A transport chain is provided on the forming transport frame, and a product placement platform is provided in the middle of the forming transport frame. Pads are provided on both sides of the placement platform, and multiple insertion holes are provided on the pads, which are mounted on the forming transport frame. A forming sleeve is installed on the insertion holes. The forming sleeve has a telescopic area composed of multiple telescopic plates. Multiple fitting arc-shaped plates are provided at the port of the forming sleeve. Electromagnetic blocks are provided at both ends of the telescopic sleeve, and a pressing component is connected inside the telescopic area. Two sets of arc-shaped forming components are provided at one end of the forming sleeve, and multiple spherical forming blocks are connected to the arc-shaped forming components. One end of the two sets of arc-shaped forming components has a hinge, and the other end of the arc-shaped forming components is connected to a support rod. A moving component that drives the two support rods to hinge is connected to the forming transport frame.
[0006] Preferably, the diameters of the holes at the connection points between the fitting arc plate and the shaping sleeve and the insertion hole are both smaller than the diameter of the telescopic area. A folding recess is provided at the connection point between the fitting arc plate and the tube opening of the telescopic area, and a conical sleeve is connected to the outside of the folding recess. A pull rod is connected between the fitting arc plate and the outer wall of the conical sleeve, and multiple electric rods are connected to the back of the conical sleeve.
[0007] Preferably, the conical sleeve has compression creases.
[0008] Preferably, the pressing component includes a connecting ring installed inside the telescopic piece, and a plurality of pressing blocks are connected to the connecting ring.
[0009] Preferably, a semi-circular support plate is provided between the shaping sleeve and the arc-shaped shaping component, and connecting rods are respectively connected to both sides of the semi-circular support plate, and the connecting rods are connected to the outside of the pad plate.
[0010] Preferably, the hinge portion is provided with a plurality of recoil springs, and the two ends of the recoil springs are respectively connected to two arc-shaped shaping components.
[0011] Preferably, the moving component includes a rocker arm with multiple bidirectional threaded sections. A threaded bushing is connected to the bottom of the support rod. Mounting seats are connected to both ends of the rocker arm. The mounting seats are connected to the shaping and transport frame. One end of the rocker arm is connected to a connecting block connected to a power device. A guide rod is connected to one of the mounting seats. A limiting sleeve that slides with the guide rod is connected to the threaded bushing.
[0012] Preferably, the top of the pad is connected to an adhesive plate that fits the product, and the bottom of the pad is connected to two support columns, which are connected to the shaping and transport frame.
[0013] Compared with the prior art, the beneficial effects of the present invention are:
[0014] This invention designs and places a platform on a shaping transport rack. A pad is placed over the product, and a shaping sleeve is installed on the outside of the pad. After the lead wires pass through the arc-shaped shaping component, the opening and closing of the arc-shaped shaping component is adjusted uniformly by a moving component. This facilitates the initial shaping of multiple lead wires inserted into the insertion holes. Then, when the lead wires are pushed into the shaping sleeve position, the bonding plate and the lead wires are bonded together to avoid shaking deviation when multiple lead wires are inserted. At the same time, the pressure component, after being attracted by two electromagnetic blocks, drives the telescopic plate to extend and retract, thereby driving the pressure component to further shape and press the lead wires. Compared with the existing method of shaping lead wires with needle-nose pliers, this method is more conducive to the automatic shaping of multiple lead wires at the same time, making the lead wire shaping process more convenient.
[0015] The bonding plate designed in this invention consists of multiple plates that fit together on the outer walls of the inserted pins, thereby improving the fit to the outside of the pins and making the pins more stably inserted into the insertion hole. Attached Figure Description

Detailed Implementation
[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0028] Please see Figure 1-10 This invention provides a technical solution: an automatic DIP lead forming machine, comprising a forming transport frame 1 and a robotic arm 11. The forming transport frame 1 is equipped with a transport chain, which is driven by a chain drive, as shown in the attached diagram. Figure 1 As shown, the conveyor chain design has two sections, and a product placement platform 2 is located in the middle of the shaping conveyor frame 1. At both ends of the conveyor chain, drive motors and other power output components are installed to drive the movement of the conveyor chain, placing the DIP square circuit board shells to be processed onto the conveyor chain for transport. Upon reaching the placement platform 2, a robotic arm 11 grasps the DIP square circuit board shell. The robotic arm 11 uses multi-axis rotation for easy grasping. The gripper of the robotic arm 11 in this design uses a general-purpose mechanical gripper; it can also use a suction method to pick up the DIP square circuit board shell, therefore a detailed illustration of the mechanical gripper is not shown in the attached diagram. The placement platform 2 can be referenced in the attached diagram. Figure 2 As shown, raised pads are set at the four corners. The contact points between the pads and the DIP square circuit board housing are rounded to avoid scratching the housing. At the same time, the bottom of the placement platform 2 is provided with through holes. The housing can be lifted by a lifting component, such as a cylinder, to facilitate the gripping of the robotic arm 11.
[0029] To facilitate the reshaping and correction of the pin lines at the pin insertion points of the housing, and to prevent the housing from deflecting, a pad 3 is designed, as shown in the attached... Figure 5 As shown;
[0030] The pads 3 are respectively set on both sides of the placement platform 2. The pads 3 can be made of high-hardness plastic or metal. A soft material, such as cloth, can be applied to the contact surface between the pads 3 and the shell to reduce wear on the shell surface. The pads 3 have multiple insertion holes 31, and countersunk holes can also be provided outside the insertion holes 31. The top of the pads 3 is connected to the bonding plate 32 that fits the product, and the bottom of the pads 3 is connected to two support columns 33. The support columns 33 are connected to the shaping and transporting frame 1, and the pads 3 are installed on the shaping and transporting frame 1.
[0031] To perform final shaping of the pins that will be inserted into the housing, a shaping sleeve 4 is designed on the outside of the corresponding position of each pin in the housing for shaping. The design of the shaping sleeve 4 is referenced in the attached document. Figure 2-4, attached Figure 6-8 As shown;
[0032] The shaping sleeve 4 is installed at the countersunk position of the insertion hole 31, and is fixed to the insertion hole 31 of the pad 3 by screws, bolts and other fasteners. The shaping sleeve 4 is provided with a telescopic area, which is composed of multiple telescopic pieces 41, as shown in the attached figure. Figure 8 As shown, the telescopic piece 41 is designed in three sets, with a gap of 60° between each pair of telescopic pieces 41. In order to improve the shaping effect of the pin line, multiple sets of telescopic pieces 41 can be added to reduce the gap angle between the telescopic pieces 41. The port part of the shaping sleeve 4 is provided with multiple fitting arc plates 42. Electromagnetic blocks 43 are provided at both ends of the telescopic sleeve, and a pressing part 5 is connected inside the telescopic area.
[0033] The diameter of the holes at the connection between the fitting arc plate 42 and the shaping sleeve 4 and the insertion hole 31 is smaller than the diameter of the telescopic area. The connection between the fitting arc plate 42 and the tube opening of the telescopic area is provided with a folding recess 44, and a conical sleeve 8 is connected to the outside of the folding recess 44. A pull rod 81 is connected between the outer wall of the fitting arc plate 42 and the conical sleeve 8, and multiple electric rods 82 are connected to the back of the conical sleeve 8. In order to facilitate the retraction of the conical sleeve 8, compression creases 83 are provided on the conical sleeve 8.
[0034] The pressing component 5 includes a connecting ring 51 installed inside the telescopic piece 41, and a plurality of pressing blocks 52 are connected to the connecting ring 51.
[0035] Before the pin wire is fully inserted into the shaping sleeve 4, the multiple fitting arc plates 42 are in an open state, which facilitates the insertion of the pin wire. After the pin wire is inserted into the opening formed by the multiple fitting arc plates 42, the electric rod 82 is opened by controlling the electric rod 82. In this way, the conical sleeve 8 moves closer to the fitting arc plate 42 from the telescopic area (the angle between the outer edge of the conical sleeve 8 and the outer edge of the conical body formed by the multiple fitting arc plates 42 gradually decreases from 160° to 120°). This causes the pull rod 81 installed on the outer wall of the conical sleeve 8 to push the fitting arc plate 42 to close. At this time, the fitting arc plate 42 changes from the original open state to the closed state, thus achieving the effect of shaping before the pin wire is inserted.
[0036] After the lead wire is shaped and bonded by the curved plate 42, the electromagnetic blocks 43 are controlled. Initially, the two electromagnetic blocks 43 are set to have the same magnetic pole, so that the telescopic plate 41 in the telescopic area is fully open. At the same time as the electric rod 82 is started, the electromagnetic blocks 43 are charged so that the two electromagnetic blocks 43 have opposite magnetic poles. Under the magnetic attraction, the telescopic plate 41 begins to retract. The connecting ring 51, which is fixedly installed on the inner wall of the telescopic plate 41, begins to drive the pressing block 52 to press the lead wire. The contact surface between the pressing block 52 and the lead wire is made of a hard material, such as metal, and its contact surface is curved, so as to achieve a better bonding effect. The upper part of the pressing block 52 is contracted and deformed, using a compression material. In this way, as the connecting ring 51 drives the pressing block 52 to move, it is convenient to move and compress at the surface position of the lead wire, thereby effectively pressing the lead wire.
[0037] To facilitate holding the lead wire, a semi-arc support plate 9 is provided between the shaping sleeve 4 and the arc-shaped shaping component 6. Connecting rods 91 are connected to both sides of the semi-arc support plate 9, and the connecting rods 91 are connected to the outside of the pad plate 3.
[0038] To perform preliminary correction of the pin lines, two sets of arc-shaped shaping components 6 are provided at one end of the shaping sleeve 4, and multiple spherical shaping blocks 61 are connected to the arc-shaped shaping components 6. One end of the two sets of arc-shaped shaping components 6 has a hinge part 62, and the other end of the arc-shaped shaping components 6 is connected to a support rod 63. The shaping transport frame 1 is connected to a moving component 7 with two support rods 63 hinged together. Multiple tension springs 64 are provided at the hinge part 62, and the two ends of the tension springs 64 are respectively connected to the two arc-shaped shaping components 6.
[0039] The moving component 7 includes a rocker arm 71 with multiple bidirectional threaded sections 72. The bottom of the support rod 63 is connected to a threaded bushing 73. Both ends of the rocker arm 71 are connected to mounting seats 74, which are connected to the shaping and transport frame 1. One end of the rocker arm 71 is connected to a connecting block 75 connected to a power device. A guide rod 76 is connected to one of the mounting seats 74, and a limiting sleeve 77 that slides with the guide rod 76 is connected to the threaded bushing 73.
[0040] Because both the upper and lower parts of the arc-shaped shaping component 6 are made of plates, and multiple arc-shaped rods are fixedly connected between the two plates, the arc-shaped rods are used to fit against the outside of the lead wire. By fixing the output shaft of the motor and the connecting block 75, when the motor is driven, it drives the rocker arm 71 to rotate. When the lead wire is pushed into the arc-shaped shaping component 6, the threaded bushing 73 on the bidirectional threaded section 72 of the rocker arm 71 begins to move, so that the two arc-shaped shaping components 6 are hinged along the hinge part 62. At the same time, multiple spherical shaping blocks 61 installed on the arc-shaped rods are pressed along the surface of the lead wire, so that the lead wire is pushed into the shaping sleeve 4 in a straight line, and the bent or folded part of the lead wire is initially shaped.
[0041] When processing the pin wires using the equipment in this solution, the DIP square circuit board housing to be processed is placed on a conveyor chain for transportation. Upon reaching the placement platform 2, a robotic arm 11 grips the DIP square circuit board housing. The robotic arm 11 employs multi-axis rotation for easy gripping. When driven by a motor, the rocker arm 71 rotates. As the pin wire is pushed into the arc-shaped shaping component 6, the threaded bushing 73 on the bidirectional threaded section 72 of the rocker arm 71 begins to move, causing the two arc-shaped shaping components 6 to hinge along the hinge portion 62. Simultaneously, multiple spherical shaping blocks 61 mounted on the arc rod press along the surface of the pin wire, thus pushing the pin wire straight into the shaping sleeve 4, correcting any external bending or deformation of the pin wire. The folded part undergoes preliminary shaping. Before the lead wire is fully inserted into the shaping sleeve 4, the multiple fitting arc plates 42 are in an open state, which facilitates the insertion of the lead wire. After the lead wire is inserted into the opening formed by the multiple fitting arc plates 42, the electric rod 82 is opened by controlling the electric rod 82. In this way, the conical sleeve 8 moves closer to the fitting arc plate 42 from the telescopic area (the angle between the outer edge of the conical sleeve 8 and the outer edge of the conical body formed by the multiple fitting arc plates 42 gradually decreases from 160° to 120°). This causes the pull rod 81 installed on the outer wall of the conical sleeve 8 to push the fitting arc plate 42 to close. At this time, the fitting arc plate 42 changes from the original open state to the closed state, thus achieving the effect of shaping before the lead wire is inserted.
[0042] After the lead wire is shaped and bonded by the curved plate 42, the electromagnetic blocks 43 are controlled. Initially, the two electromagnetic blocks 43 are set to have the same magnetic pole, so that the telescopic plate 41 in the telescopic area is fully open. At the same time as the electric rod 82 is started, the electromagnetic blocks 43 are charged so that the two electromagnetic blocks 43 have opposite magnetic poles. Under the magnetic attraction, the telescopic plate 41 begins to retract. The connecting ring 51, which is fixedly installed on the inner wall of the telescopic plate 41, begins to drive the pressing block 52 to press the lead wire. The contact surface between the pressing block 52 and the lead wire is made of a hard material, such as metal, and its contact surface is curved, so as to achieve a better bonding effect. The upper part of the pressing block 52 is contracted and deformed, using a compression material. In this way, as the connecting ring 51 drives the pressing block 52 to move, it is convenient to move and compress at the surface position of the lead wire, thereby effectively pressing the lead wire.
