Description

Technical Field

[0001] This invention relates to the field of electronic component processing technology, and specifically to an automatic pin shaping device for TO-type components. Background Technology

[0002] TO-type components are commonly used small outline packaged devices. Before being used for surface mounting, TO-type components typically undergo lead shaping. Only components that pass the shaping process can be used for surface mounting by Electron. Currently, lead shaping of TO-type components is generally done manually. This requires manually removing the TO-type components from a strip-shaped packaging box (containing multiple TO-type components arranged in a straight line) and then manually shaping the leads one by one. This method is not only time-consuming and labor-intensive, resulting in low overall efficiency, but also makes it difficult to guarantee the consistency of product quality.

[0003] In the prior art, for example, there is a tooling for one-time forming of TO packaged power transistor pins with publication number CN108615684A and a device for secondary forming of TO packaged power transistor pins with publication number CN208131859U. Although the above technical solutions have improved and optimized the product quality consistency of TO type components, they still require manual addition of components one by one, and the overall work efficiency is still low. Summary of the Invention

[0004] To address the problems of time-consuming, labor-intensive, and inefficient lead shaping of TO-type components in existing technologies, this invention provides an automatic lead shaping device for TO-type components, which can improve lead shaping efficiency and ensure product quality consistency of TO-type components.

[0005] It adopts the following technical solution:

[0006] An automatic lead shaping device for TO-type components includes a frame with an elongated slot for removing packaging boxes. On one side of the slot's width direction, there is a material rack for stacking multiple packaging boxes and a feeding mechanism for pushing the packaging boxes. The lower part of the material rack has a lateral opening that allows only one packaging box to pass through. On the other side of the slot's width direction, there is a material support mechanism. On one side of the slot's length direction, there is a feeding mechanism for pushing the components inside the packaging boxes one by one, and on the other side, there is a shaping mechanism for bending and cutting leads.

[0007] Furthermore, the feeding mechanism includes a first linear reciprocating mechanism and a connected feeding plate, which can push a packaging box onto the material support mechanism through a side opening;

[0008] The material support mechanism includes a second linear reciprocating mechanism and a connected material support plate. When the feeding mechanism pushes the material, the material support plate receives the pushed material and positions it on the slot. When the feeding mechanism empties the components in the packaging box, the material support plate retracts, causing the empty packaging box to fall into the slot.

[0009] Furthermore, the shaping mechanism includes a shaping base, a pushing mechanism capable of linear reciprocating motion is provided on one side of the shaping base, and a pressing mechanism, a bending mechanism, a cutting mechanism and a transferring mechanism are provided on the other side of the shaping base;

[0010] The shaping base is provided with a positioning groove with a side opening in the length direction of the groove, a channel for the pushing mechanism to move telescopically, and a guide block for the pushing mechanism to guide the material. The channel is connected to the positioning groove and leads to the guide block.

[0011] The guide block has an upper plane, a vertical side plane, and a limiting stop located on the opposite side of the side plane; wherein, the limiting stop is used to position the side and bottom of the component housing, the upper plane is used to support the component pins and cooperate with the clamping mechanism and bending mechanism to complete the clamping and bending actions, and the side plane is used to limit the bent pins and cooperate with the lead cutting mechanism to complete the cutting action.

[0012] Furthermore, the clamping mechanism includes a bracket, on which a horizontally telescopic fourth linear reciprocating mechanism is provided. The telescopic end of the fourth linear reciprocating mechanism is connected to a first hinge seat. The first hinge seat is hinged to a second hinge seat via a connecting rod. The second hinge seat is connected to a vertically arranged first guide rail to form a linear guiding fit. A clamping block is fixedly connected to the second hinge seat. By pressing down on the clamping block, the component pins are temporarily clamped on the upper surface of the guide block.

[0013] Furthermore, the first hinge is also connected to a horizontally positioned second guide rail to form a linear guiding fit.

[0014] Furthermore, the bending mechanism includes a fifth linear reciprocating mechanism that extends and retracts vertically on the support. The extension end of the fifth linear reciprocating mechanism is connected to a bending block, and the bending motion is formed by the downward movement of the bending block in cooperation with the guide block.

[0015] Furthermore, the cutting mechanism includes a horizontally arranged sixth linear reciprocating mechanism, the telescopic end of which is connected to a cutter, and the cutting direction is toward the side plane of the guide block.

[0016] Furthermore, the feeding mechanism includes a feeding plate and a seventh linear reciprocating mechanism connected to the feeding plate. The seventh linear reciprocating mechanism is electrically connected to the control module to control the seventh linear reciprocating mechanism to move a distance equal to the width dimension of the component each time.

[0017] Furthermore, the frame is also equipped with a baffle, which is located at the edge of the slot and on the opposite side of the feeding mechanism, to prevent the packaging box from being pulled out of the slot range when the material support mechanism retracts.

[0018] Furthermore, the frame is also equipped with a receiving box for collecting the shaped components.

[0019] The advantages of this invention compared to the prior art are as follows:

[0020] 1. By setting up a feeding mechanism, a supporting mechanism, and a feeding structure, this invention enables the feeding of components one by one without removing them from the packaging box, reducing auxiliary process time. At the same time, in conjunction with the shaping mechanism, it realizes automatic positioning, bending, and cutting of leads, thereby improving the overall efficiency of component shaping.

[0021] 2. This invention, by setting a shaping base in the shaping mechanism, enables the guide block to cooperate with the clamping mechanism, bending mechanism, lead cutting mechanism, and material transfer mechanism, ensuring the consistency of lead shaping quality. In particular, the clamping mechanism adopts a structure with the first and second hinge seats and the connecting rod hinged together, which has the following advantages compared with the direct-connection linear reciprocating mechanism: First, under the premise of the same amount of movement in the linear reciprocating mechanism, the stroke distance of this structure is smaller, resulting in higher positioning accuracy and more stable clamping; Second, the downward force of this structure is larger, which can press the lead tighter and flatter, which is beneficial to the bending and shaping of the subsequent bending mechanism and ensures the consistency of device shaping.

[0032] To make the present invention clearer, the following description, in conjunction with the accompanying drawings, further illustrates an automatic pin shaping device for TO-type components according to the present invention. The specific embodiments described herein are for illustrative purposes only and are not intended to limit the present invention.

[0033] like Figure 2 As shown, an automatic pin-shaping device for TO-type components includes a frame 1, which is a box structure with its upper surface serving as a bearing surface. A long, narrow slot 11 is formed on the upper surface of the frame 1, the size of which is larger than the size of the TO-type component packaging box, for discharging the packaging box. This slot can also serve as the entrance to a discharge channel that passes through the frame 1. The packaging box 100 is a cube, elongated in shape, with open ends along its length. TO-type components (hereinafter referred to as components) are arranged in a straight line inside the box, with the pins of each component facing the same side along the width of the packaging box, as shown in the diagram. Figure 1 As shown. Here, the width direction of a single component is defined as the length direction of the packaging box.

[0034] Combined Figure 2 , Figure 3As shown in the figure, a material rack 2 is provided on one side in the width direction of the notch 11. The material rack 2 is composed of two profiles 21 with a "C"-shaped cross-section. The profiles 21 have a certain height and are vertically connected to the bearing surface of the machine frame 1. Here, the two profiles 21 are arranged face to face and spaced apart by a certain distance, and multiple packaging boxes can be stacked and limited between the two profiles 21 to form a clearance fit. On the side walls of the two profiles 21 near the bottom, there are lateral openings 22, and the lateral openings 22 are located on the side close to the notch 11. The notch formed by the two lateral openings 22 can only allow one packaging box to pass horizontally from the side of the material rack 2.

[0035] A feeding mechanism 3 is provided between the two profiles 21. The feeding mechanism 3 includes a first linear reciprocating mechanism 31 connected to the bearing surface of the machine frame 1. The first linear reciprocating mechanism 31 moves telescopically in the horizontal direction, and its telescopic direction faces the lateral opening. A feeding plate 32 is connected to the telescopic end of the first linear reciprocating mechanism 31. The end face of the feeding plate 32 in the moving direction can pass through the lateral opening 22 with a clearance, and the stacked packaging boxes at the bottom are pushed from the lateral opening 22 towards the notch 11 by the pushing of the feeding plate 32.

[0036] A material supporting mechanism 4 is provided on the other side in the width direction of the notch 11. The material supporting mechanism 4 includes a second linear reciprocating mechanism 41 connected to the bearing surface of the machine frame 1. The telescopic end of the second linear reciprocating mechanism 41 is connected to a material supporting plate 42. The material supporting plate 42 can extend to directly above the notch 11 to receive the packaging boxes pushed by the feeding mechanism 3. The upper surface of the material supporting plate 42 is not higher than the upper surface of the feeding plate 32. Here, the moving direction of the second linear reciprocating mechanism 41 is preferably set in the horizontal direction and faces the direction of the lateral opening 22; positioning structures such as retaining edges for positioning the packaging boxes can be provided on the material supporting plate 42.

[0037] A feeding mechanism 5 for pushing the components in the packaging box one by one is provided on one side in the length direction of the notch 11, and a shaping mechanism 6 for bending and trimming the feet is provided on the other side.

[0038] Among them, the structure of the feeding mechanism 5 is preferably as follows: As Figure 4 shown, the feeding mechanism 5 includes a feeding plate 51 and a seventh linear reciprocating mechanism 52 connected to the feeding plate. The cross-sectional size of the feeding plate 51 is smaller than the end opening size of the packaging box, and the feeding plate 51 can push the components out of the packaging box through this opening. The seventh linear reciprocating mechanism 52 is electrically connected to a control module (not shown in the figure) to control the moving distance of the seventh linear reciprocating mechanism each time to be the width size of the component. Of course, the stroke of the seventh linear reciprocating mechanism 52 should be greater than the length size of the packaging box; the seventh linear reciprocating mechanism is preferably a servo electric cylinder to facilitate the control of the moving accuracy of its moving end. In addition, considering that the seventh linear reciprocating mechanism has a relatively large volume due to its large stroke, the seventh linear reciprocating mechanism can be arranged inside the machine frame 1.

[0039] To improve the accuracy and consistency of component shaping, the shaping mechanism 6 adopts the following structure: [Combined with...] Figure 5 , Figure 6 As shown, it includes a shaping base 61. A pushing mechanism 62 capable of linear reciprocating motion is provided on one side of the shaping base 61. The moving direction of the pushing mechanism 62 is perpendicular to the length direction of the slot 11. On the other side of the shaping base 61 are a pressing mechanism 63, a bending mechanism 64, a cutting mechanism 65, and a transferring mechanism 66. A receiving box 7 for collecting shaped components is also provided on the frame 1, located at the pushing outlet end of the transferring mechanism 66.

[0040] The shaping base 61 includes a positioning groove 611 with an opening along the length of the slot 11, a channel 612 for the telescopic movement of the pushing mechanism 62, and a guide block 613 for the transferring mechanism 66 to guide the pushing. The channel 612 is connected to the positioning groove 611 and extends perpendicularly to the guide block 613. The positioning groove 611 and the channel 612 have coplanar sidewalls serving as a positioning reference. When the pushing mechanism 62 pushes the component, it moves along the positioning reference. Both the pushing mechanism 62 and the transferring mechanism 66 adopt a conventional structure of a linear reciprocating transferring mechanism + push plate.

[0041] The guide block 613 is a strip structure with an upper plane 613a, a vertical side plane 613b, and a limiting stop 613c located on the opposite side of the side plane. Here, the limiting stop 613c is used to position the side and bottom of the component housing, and the bottom surface is coplanar with the bottom surface of the channel 612. The upper plane 613a of the guide block 613 is used to support the component pins and cooperate with the clamping mechanism 63 and the bending mechanism 64 to complete the clamping and bending actions. The side plane 613b of the guide block 613 is used to limit the bent pins and cooperate with the cutting mechanism 65 to complete the cutting action.

[0042] like Figure 7As shown, the clamping mechanism 63 includes a bracket 631 fixed on the bearing surface. The bracket 631 has a Z-shaped cross-section. A horizontally telescopic fourth linear reciprocating mechanism 632 is fixedly connected to the outer wall of the bracket 631. The telescopic end of the fourth linear reciprocating mechanism passes through the bracket 631 and is connected to the first hinge seat 633. The first hinge seat 633 is connected to the second hinge seat 635 through a connecting rod 634. The second hinge seat 635 is connected to the vertically arranged first guide rail 636 to form a linear guiding fit. A clamping block 637 is fixedly connected to the second hinge seat. When the fourth linear reciprocating mechanism 632 drives the first hinge seat 633 to move forward, the component pins are temporarily clamped on the upper plane of the guide block 613 by pressing down the plane at the lower end of the clamping block 637. The first and second hinge seats each have two support plates with coaxial through holes. The two ends of the connecting rod are respectively provided with hinge holes. The through holes and hinge holes are connected by the hinge shaft to achieve hinged engagement. The second hinge seat 635 can form a guiding engagement by setting a sliding groove that slides with the first guide rail 636, or it can form a guiding engagement by using a slider + linear track.

[0043] Of course, considering the stability of the pressing mechanism 63, the fourth linear reciprocating mechanism 632 can be a guided cylinder. Its guide structure can be directly integrated into the cylinder, or a separate guide structure can be provided, for example... Figure 7 As shown, a second guide rail 638 is provided on the back of the top plate of the bracket 631. The axial direction of the second guide rail 638 is collinear with the cylinder extension and retraction path. The first hinge seat 633 adopts the same guiding and mating structure as the second hinge seat 635 and is connected to the second guide rail 638.

[0044] Here, the clamping mechanism 63 not only serves to tighten and fix the pins, facilitating cooperation with other mechanisms to improve the stability and consistency of bending and cutting actions, but also clamps and flattens the pins. In particular, the structure employing the hinged connection of the first and second hinge seats and the connecting rod, such as... Figure 8 As shown, if the second hinge is located to the lower left of the first hinge, when the first hinge is subjected to a horizontal pulling force to the left, the first hinge moves to the left, simultaneously causing the connecting rod to move downwards. The connecting rod tends to become vertical, thus causing the second hinge to move downwards under the guidance of the first guide rail 636. During this process, it can be seen that the vertical component of the connecting rod is greater than the horizontal component. This means that the structure can provide a larger downward force, which can press the pin tighter and flatter, facilitating the bending and shaping of the subsequent bending mechanism and ensuring the consistency of the device shaping. Furthermore, the vertical movement distance of the second hinge is less than the horizontal movement distance of the first hinge, resulting in higher and more stable clamping and positioning accuracy.

[0045] Furthermore, the bending mechanism 64 includes a fifth linear reciprocating mechanism 641 that extends and retracts vertically on the bracket 631. The extension end of the fifth linear reciprocating mechanism 641 passes through the top plate of the bracket 631 and is connected to the bending block 642. Through the downward movement of the bending block 642, the bending block 642 and the side plane 613b of the guide block 613 move relative to each other, pressing the pin downward to form a bending motion.

[0046] Furthermore, the lead-cutting mechanism 65 includes a horizontally arranged sixth linear reciprocating mechanism 651, which is fixed to the bearing surface. Its telescopic end is connected to a cutter 652. The cutting blade 652 moves towards the side plane of the guide block 613. When cutting component leads, the bent leads rest against the side plane of the guide block 613, and the cutting blade 652 moves to this side plane to cut the leads. Considering the structure and placement of the bracket 631, clearance holes can be provided on the bracket 631 to avoid obstructing the movement path of the cutting blade 652.

[0047] In some embodiments, the linear reciprocating motion mechanism not specifically mentioned above can be an electric cylinder, a pneumatic cylinder, or a hydraulic cylinder. Considering that this device needs to improve working efficiency, have a fast working cycle, and have good working stability, the linear reciprocating motion mechanism preferably uses a pneumatic cylinder with a guide structure. The guide structure can be an integrated structure on the pneumatic cylinder, which can be purchased commercially, or a separately set guide structure, such as a conventional guide rail + guide groove, slider + linear guide rail, slider + guide post, etc.

[0048] In some embodiments, in order to ensure that the packaging box can fall smoothly into the slot 11 when the material support mechanism 4 retracts, a baffle 43 is also provided on the frame 1. The baffle 43 is located at the edge of the slot 11 and on the opposite side of the feeding mechanism 3, which restricts the packaging box that may be driven by the retraction of the material support mechanism 4 within the range of the slot 11.

[0049] The working process of this device:

[0050] 1. Stack multiple boxes containing components in the material rack 2;

[0051] 2. The feeding mechanism 3 pushes the packaging box at the bottom onto the support plate 42, so that the packaging box is accurately positioned above the slot 11;

[0052] 3. The feeding mechanism 5 operates, extending the feeding plate 51 from the opening side of the packaging box, and pushing each individual component into the positioning groove of the shaping mechanism 6 for positioning through the control module.

[0053] 4. In the shaping mechanism 6, the pushing mechanism 62 pushes the component to the guide block 613 for positioning, and then the clamping mechanism 63 clamps and fixes the component pins. Subsequently, the bending mechanism 64 and the cutting mechanism 65 perform the corresponding bending and cutting actions in sequence. Finally, the pushing mechanism 62 pushes the shaped component to a length of one component width, and multiple shaped components are lined up in a row towards the receiving box 7.

[0054] 5. Repeat steps 3-4 until all components inside the packaging box have been shaped, and then reset the feeding mechanism 5.

[0055] 6. The material tray 42 retracts, and the empty packaging box falls into the slot 11 for outward discharge.

[0056] This device can automatically shape the pins of components along with their packaging boxes, allowing each component to be shaped one by one within a working cycle. Compared to manual feeding, this method improves the overall efficiency of component pin shaping. At the same time, the combined operation of multiple mechanisms ensures the consistency of component product quality.

[0057] The above embodiments of the present invention are merely examples for clearly illustrating the present invention and are not intended to limit the implementation of the present invention. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. However, obvious variations or modifications derived from the essential spirit of the present invention still fall within the protection scope of the present invention.
