Description

Technical Field

[0001] The present invention relates to the technical field of electronic component processing, in particular to an electronic component pin processing device, and also to a processing system having the electronic component pin processing device, and a processing method using the electronic component pin processing device. Background Art

[0002] In the manufacturing process of electronic equipment, it is necessary to assemble and weld electronic components to integrated circuit boards. In the automated production process, it is necessary to ensure that the parameters such as the pin mounting height and pin position of the electronic components meet the design of the integrated circuit board. Therefore, before assembling and welding the electronic components to the integrated circuit board, the pins of the electronic components need to be shaped, formed, cut, etc. In the prior art, the shaping, forming, and cutting processes are performed manually, which has low production efficiency. Summary of the invention

[0003] The purpose of the present invention is to provide an electronic component pin processing device, which can automatically complete the external expansion processing of the first pin of the electronic component, thereby improving the work efficiency and the yield rate.

[0004] The present invention provides an electronic component pin processing device, which includes a component positioning module, a driving module, a sliding module and an expansion module. The component positioning module is used to position an electronic component, and the electronic component includes two first pins. The sliding module includes a sliding body, on which a push rod connecting part and a rotating driving member are fixedly arranged; the push rod connecting part is connected to the push rod of the driving module, and can move toward the component positioning module along a first sliding direction under the drive of the push rod. A first elastic member is connected between the expansion module and the sliding module, and two expansion driving rods are arranged on the expansion module, and an insertion part is arranged at one end of each expansion driving rod. Wherein, during the movement of the sliding module along the first sliding direction, after the sliding module drives the two insertion parts to insert between the two first pins, the rotating driving member can continue to move along the first sliding direction relative to the expansion module, and drive the two expansion driving rods to rotate in opposite directions, so as to drive the insertion part to expand the two first pins. The electronic component pin processing device can automatically complete the outward expansion processing of the first pin of the electronic component, thereby improving work efficiency and yield rate. During the movement of the sliding module toward the component positioning module, the driving insertion part is inserted between the two first pins of the electronic component. Through the mutual cooperation of the rotating driving member and the outward expansion driving rod, the linear motion of the sliding module is converted into the rotational motion of the outward expansion driving rod, thereby realizing the outward expansion operation of the first pin by the insertion part.

[0005] In another schematic embodiment of the electronic component pin processing device of the present invention, the outward expansion module includes an outward expansion base, two rotating shafts and two outward expansion drive rods. The end of the outward expansion base facing away from the component positioning module is connected to the sliding module through the first elastic member. The two rotating shafts are stationary relative to the outward expansion base. The two outward expansion drive rods are arranged on the outward expansion base, and the other end of each outward expansion drive rod is connected to one of the rotating shafts. Among them, the area between the two outward expansion drive rods includes a sliding area, and the rotating drive member partially extends into the sliding area and can move therein. The electronic component pin processing device is exquisitely designed and easy to implement.

[0006] In another exemplary embodiment of the electronic component pin processing device of the present invention, in the first sliding direction, the sliding area includes a first area and a second area in sequence; when the rotary drive member moves from the first area to the second area, the rotary drive member can push the two outward expansion drive rods to rotate around their corresponding rotation axes. The electronic component pin processing device has a simple structure and is easy to implement.

[0007] In another schematic embodiment of the electronic component pin processing device of the present invention, the rotary drive member is a cylinder whose axial direction is parallel to the axial direction of the rotating shaft; the rotary drive member passes through the oblong hole on the outwardly expanded base and extends into the sliding area.

[0008] In another schematic embodiment of the electronic component pin processing device of the present invention, in the first sliding direction, the outward expansion drive rod includes a first section of the drive rod, a second section of the drive rod, a third section of the drive rod, and a fourth section of the drive rod in sequence. The first section of the drive rod is connected to the rotating shaft. The first area is formed between the second section of the drive rod and the second section of the drive rod of another outward expansion drive rod. The second area is formed between the third section of the drive rod and the third section of the drive rod of another outward expansion drive rod. The end of the fourth section of the drive rod protrudes to form the insertion portion. A second elastic member is connected between the third section of the drive rod or the fourth section of the drive rod and the plate body of the adjacent outward expansion base. The outward expansion drive rod of the electronic component pin processing device can automatically reset after completing the outward expansion operation and leaving the component positioning module, which is convenient for the next outward expansion operation.

[0009] In another exemplary embodiment of the electronic component pin processing device of the present invention, the outward expansion module further includes a drive rod limiting column. The drive rod limiting column is disposed between the two outward expansion drive rods and is stationary relative to the outward expansion base, and the outward expansion drive rod can be abutted against the drive rod limiting column under the action of the second elastic member. By providing the drive rod limiting column, it can be ensured that the spacing between the two insertion parts after resetting meets the requirements, so that the insertion part can be smoothly inserted between the two first pins of the next electronic component.

[0010] In another schematic embodiment of the electronic component pin processing device of the present invention, the expansion module further includes an expansion positioning piece. The expansion positioning piece is fixedly mounted on the expansion base, and the expansion positioning piece protrudes toward the component positioning module to form a positioning protrusion, and when the expansion module moves to the component positioning module, the positioning protrusion can abut against the pin of the electronic component. When the insertion portion expands the first pin outward, the positioning protrusion can cooperate with the component positioning module to clamp the upper end of the pin to prevent the expansion operation from damaging the pin of the electronic component.

[0011] In another exemplary embodiment of the electronic component pin processing device of the present invention, the sliding module further includes a U-shaped stopper. The U-shaped stopper is fixedly disposed on the sliding body; a sliding channel is formed between the U-shaped stopper and the sliding body, and the U-shaped stopper and the sliding body can limit the movement of the expansion module in a direction perpendicular to the first sliding direction. In this way, the sliding module can only move in the first sliding direction and the opposite direction thereof, so as to ensure that the insertion portion can be accurately inserted between the two first pins of the electronic component.

[0012] In another schematic embodiment of the electronic component pin processing device of the present invention, the electronic component pin processing device also includes a base module, and the base module includes a base body and a base first limiter. A base sliding groove is formed on the base body, and the sliding module is arranged on the base body and can move along the first sliding direction in the base sliding groove. The base first limiter is fixedly arranged at one end of the base body facing the component positioning module, and a stopper is arranged on the base first limiter, and the base module can be abutted against the component positioning module through the stopper. By setting the base first limiter, the placement position of the base module can be quickly determined according to the component positioning module.

[0013] In another exemplary embodiment of the electronic component pin processing device of the present invention, the component positioning module further includes two pin positioning blocks. The pin of the electronic component is arranged between the two pin positioning blocks, and the insertion portion can push the first pin to undergo outward expansion deformation until the first pin abuts against the adjacent pin positioning block. The two pin positioning blocks can ensure that the spacing between the two first pins after outward expansion meets the requirements.

[0014] The present invention also provides an electronic component pin processing system, which includes any of the above electronic component pin processing devices and a pin forming device. The pin forming device is used to form the pins of electronic components, and includes a first support seat, a second support seat and a forming slider. The first support seat includes a forming support portion. A slider limiter and a cutting block are fixedly arranged on the second support seat; a slider sliding groove is arranged on the slider limiter, and the slider sliding groove extends along the second sliding direction; the cutting block is arranged between the second support seat and the slider limiter, and a cutting portion is arranged on the surface thereof facing the first support seat. A forming structure cooperating with the forming support portion is arranged at one end of the forming slider facing the first support seat, and the end thereof facing away from the first support seat is arranged in the slider sliding groove, and a third elastic member is arranged between the forming slider and the slider limiter. Among them, when the second support seat moves relative to the first support seat along the sliding direction, the molding slider can squeeze the pin located at the molding support portion under the action of the third elastic member to mold the pin of the electronic component through the molding structure, and the cutting block can continue to move relative to the molding slider along the second sliding direction under the action of the second support seat to cut the pin of the electronic component. The electronic component pin processing system can automatically complete the expansion, molding, and cutting operations of the electronic component pins to meet the design requirements of the integrated circuit board, and its structure is simple, which improves production efficiency and yield rate.

[0015] In another exemplary embodiment of the electronic component pin processing system of the present invention, a first limiting ridge is formed on the plane of the forming support portion facing the forming slider, and the extension direction of the first limiting ridge is perpendicular to the second sliding direction shown and the extension direction of the electronic component pin; the forming structure of the forming slider includes a first limiting groove; wherein, when the second support seat moves relative to the first support seat along the second sliding direction, the first limiting ridge can extend into the first limiting groove, and cooperate with the first limiting groove to bend the portion of the pin located at the position of the first limiting groove. By setting the first limiting ridge and the first limiting groove, the pin forming device can set a bending portion on the first pin to accurately control the pin mounting height of the electronic component.

[0016] In another exemplary embodiment of the electronic component pin processing system of the present invention, a second limiting groove is further provided on the plane where the first limiting convex ridge is located, a first supporting surface and a second limiting inclined surface are provided in the second limiting groove, the first supporting surface is perpendicular to the second sliding direction, the angle between the second limiting inclined surface and the first supporting surface is greater than 90 degrees and faces the free end of the pin in the extension direction of the pin; the molding structure of the molding slider also includes a second limiting convex portion, and the second limiting convex portion is provided with a second supporting surface that cooperates with the first supporting surface and a first limiting inclined surface that cooperates with the second limiting inclined surface. The pin molding device of the present invention can bend the second pin by providing the second limiting groove and the second limiting convex portion, and accurately control the bending angle and bending length of the second pin. Through this device, the bending portion of the first pin of the electronic component and the bending section of the middle pin (i.e., the second pin 13) can be formed simultaneously, thereby improving production efficiency.

[0017] The present invention also provides a method for processing the pins of electronic components, which is applied to any of the above-mentioned electronic component pin processing systems, wherein the electronic component is a two-color indicator light, and the method for processing the pins of electronic components comprises: shaping the pins of the electronic component so that its two first pins and the third pin remain in the same plane; expanding the two first pins by the electronic component pin processing device to form a first bending section; detecting the polarity of the electronic component; and forming a bending portion on the first pin and a second bending section on the third pin by the pin forming device. The processing method can automatically complete the entire processing flow of the pins of the electronic component (including shaping, expansion, forming, and cutting), which not only improves the production efficiency, but also ensures that the polarity of the processed electronic component meets the requirements.

[0018] In another exemplary embodiment of the electronic component pin processing method of the present invention, the detecting the polarity of the electronic component includes: if the polarity is incorrect, rotating the electronic component by 180° and detecting the polarity of the electronic component again. This processing method improves the yield rate. BRIEF DESCRIPTION OF THE DRAWINGS

[0063] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific embodiments of the present invention are now described with reference to the accompanying drawings. In the drawings, the same reference numerals represent components with the same structure or similar structures but the same functions.

[0064] In this document, “exemplary” means “serving as an example, instance or illustration”, and any diagram or implementation described in this document as “exemplary” should not be interpreted as a more preferred or more advantageous technical solution.

[0065] In order to simplify the drawings, only the parts related to the present invention are schematically shown in each figure, and they do not represent the actual structure of the product. In addition, in order to simplify the drawings and facilitate understanding, in some figures, only one of the parts with the same structure or function is schematically drawn or marked.

[0066] In this article, "one" not only means "only one", but also means "more than one". In this article, "first", "second", etc. are only used to distinguish each other, rather than to indicate their importance and order, etc. The electronic components referred to in this article have pins, especially electronic components with three pins, such as LED two-color indicator lights, etc. The extension direction B of the pins referred to in this article refers to the extension direction of the pins when the electronic component 10 is placed at the first support seat 80 but the pins have not been processed yet. The installation height of the pins referred to in this article refers to the height of the pins above the integrated circuit board when the pins are placed on the integrated circuit board.

[0067] Figure 1 It is a schematic diagram for explaining the structure of an unprocessed two-color indicator light and a fully processed two-color indicator light of the present invention.

[0068] Figure 1 The left side of the figure shows a schematic structural diagram of an unprocessed two-color indicator light. Figure 1 The right side of the figure shows a schematic diagram of the structure of a two-color indicator light that has completed all processing.

[0069] Usually, the pins of the two-color indicator lights purchased from the market are of conventional shape, and the shape of the pins is not specially processed. In order to make the pins of the two-color indicator lights meet the design of a specific integrated circuit board, the pins of the two-color indicator lights need to be processed. The processing requires adjusting the three pins of the two-color indicator lights so that they form a specific spacing between each other to ensure that the two-color indicator lights can be smoothly inserted into the three jacks at the corresponding positions of the integrated circuit board. Specifically, it is necessary to expand the first pins 11 and 12, and bend the second pin. In addition, it is also necessary to form an elevated positioning portion on the three pins to control the elevated height of the two-color indicator lights on the integrated circuit board. For example, the bending portions 111 and 121 on the first pins 11 and 12 are the elevated positioning portions provided on the first pins 11 and 12; the bending point between the second bending section 131 on the second pin 13 and the free end of the second pin 13 is the elevated positioning portion provided on the second pin 13. Finally, it is also necessary to cut off the excess length of the pins.

[0070] Figure 2 It is a schematic diagram for explaining the structure of the electronic component pin processing device of the present invention. Figure 5 A top view for explaining the electronic component pin processing device of the present invention ( Figure 5 The component positioning module 20 in the figure only shows the pin positioning block 21 and the electronic component 10 arranged thereon, and other parts are omitted and not shown).

[0071] See also Figure 2 , Figure 5 , which shows a schematic method of the electronic component pin processing device of the present invention, the electronic component pin processing device can perform outward expansion processing on the first pins 11 and 12.

[0072] The electronic component pin processing device includes a component positioning module 20 , a sliding module 50 , an expansion module 60 and a driving module 40 .

[0073] The component positioning module 20 is used to position an electronic component 10 (eg Figure 1 The electronic component 10 includes two first pins 11 and 12 and a second pin 13. The component positioning module 20 can be fixed on a workbench, which includes a work station. During operation, the tool can be controlled to clamp an electronic component 10 and place it in the work station, thereby ensuring that the pins of each electronic component 10 located in the work station are in the same position and maintain the same height.

[0074] The driving module 40 includes a cylinder and a push rod 41 disposed on the cylinder. The driving module 40 may also adopt other driving devices, such as a motor drive. The driving device 40 can drive the push rod 41 thereon to move toward the direction of the component positioning module 20.

[0075] The sliding module 50 is arranged between the component positioning module 20 and the driving module 40. The sliding module 50 includes a sliding body. The sliding body is provided with a push rod connection portion 51 and a rotating driving member 54. The push rod connection portion 51 and the rotating driving member 54 are fixed to the sliding body and cannot move relative to the sliding body. For example, the push rod connection portion 51 and the rotating driving member 54 can be fixedly installed on the sliding body by fixing screws. The push rod connection portion 51 is installed on the push rod 41 of the driving module 40, and the push rod 41 can drive the push rod connection portion 51 to move toward the component positioning module 20 along the first sliding direction A.

[0076] The expansion module 60 is arranged on the sliding module 50, and can slide relative to the sliding module 50 along the first sliding direction A and the opposite direction. A first elastic member 52 is arranged between the expansion module 60 and the sliding module 50. One end of the first elastic member 52 is connected to the push rod connecting portion 51, and the other end is connected to the end of the expansion module 60 that is away from the component positioning module 20. When the push rod 41 drives the sliding module 50 to move along the first sliding direction, the sliding module 50 can provide the expansion module 60 with a force along the first sliding direction A through the friction between the expansion module 60 and / or the elastic force of the first elastic member 52. Two expansion drive rods 62 (see Figure 3 ), an insertion portion 625 is provided at one end of each outward expansion driving rod 62, and the end of the insertion portion 625 faces the component positioning module 20.

[0077] During operation, the push rod 41 of the driving module 40 drives the sliding module 50 to move toward the component positioning module 20 along the first sliding direction A. The sliding module 50 drives the expansion module 60 to move toward the component positioning module 20 together, so that the two insertion parts 625 in the expansion module 60 arrive at the component positioning module 20 and are inserted between the two first pins 11 and 12. At this time, the expansion module 60 stops moving due to the stopper of the component positioning module 20. The push rod 41 continues to drive the sliding module 50, and the sliding module 50 compresses the first elastic member 52 to continue to move toward the component positioning module 20 relative to the expansion module 60. Driven by the sliding body, the rotating driving member 54 on the sliding module 50 drives the two expansion driving rods 62 to rotate in opposite directions to drive the two insertion parts 625 to expand the two first pins 11 and 12. The electronic component pin processing device can automatically complete the outward expansion processing of the first pin of the electronic component, thereby improving work efficiency and yield rate. During the movement of the sliding module toward the component positioning module, the driving insertion part is inserted between the two first pins of the electronic component. Through the mutual cooperation of the rotating driving member and the outward expansion driving rod, the linear motion of the sliding module is converted into the rotational motion of the outward expansion driving rod, thereby realizing the outward expansion operation of the first pin by the insertion part.

[0078] A base module 30 may be provided on the electronic component pin processing device to support the sliding module 50. Specifically, the base module 30 includes a base body. A base sliding groove 33 is formed on the base body, and the base sliding groove 33 extends along the first sliding direction A. The sliding module 50 is provided on the base body and can move along the first sliding direction A on the base sliding groove 33.

[0079] Figure 3 for Figure 2 Schematic diagram of the exploded view of the electronic component pin processing device. Figure 4 for Figure 2 Schematic diagram of partial structure of electronic component pin processing device.

[0080] like Figure 4 As shown, the expansion module 60 includes an expansion base 61 , two rotation axes and two expansion driving rods 62 .

[0081] The outward expansion base 61 is provided with a receiving space for receiving two outward expansion drive rods 62. An opening is provided at one end of the receiving space facing the component positioning module 20 to allow the insertion portion 625 of the outward expansion drive rod 62 to extend out of the receiving space. The end of the outward expansion base 61 that is away from the component positioning module 20 is connected to the sliding module 50 through the first elastic member 52.

[0082] The two rotating shafts are stationary relative to the outward expansion base 61. The rotating shaft can be a cylindrical structure, and one end of the cylindrical structure is limited on the outward expansion base 61, so as to prevent the rotating shaft from moving relative to the outward expansion base 61.

[0083] Two outward expansion drive rods 62 are arranged on the outward expansion base 61. A shaft mounting hole 621 is arranged at one end of each outward expansion drive rod 62 away from the insertion portion 625. Each outward expansion drive rod 62 is sleeved on a rotation shaft through the shaft mounting hole 621 thereon, and the outward expansion drive rod 62 can rotate around its corresponding rotation shaft. A sliding area 67 is formed in the area between the two outward expansion drive rods 62, and the rotation drive member 54 on the sliding module 50 partially extends into the sliding area 67 and can move in the sliding area.

[0084] Specifically, Figure 4 As shown, the rotary drive member 54 can be designed as a cylinder, whose axial direction is parallel to the axial direction of the rotating shaft. One end of the axial direction is limited on the sliding module 50, and the other end passes through the oblong hole on the outward expansion base 61 and extends into the sliding area 67.

[0085] In order to prevent foreign matter from invading the rotation range of the outward expansion driving rod 62 during operation, a cover plate 66 can be provided on the outward expansion base 61 to cover the accommodation space and ensure the reliability of the device. The cover plate 66 can be fixed on the outward expansion base 61 by screws.

[0086] like Figure 4 As shown, the base module 30 may also be provided with a first base stopper 31 and two second base stoppers 32. The first base stopper 31 is fixed to one end of the base body facing the component positioning module 20. The first base stopper 31 adopts a U-shaped design, with two free ends fixed to the base body, and the portion between the two free ends is a stopper 311, which is located between the base body and the component positioning module 20. The base module 30 can be abutted against the component positioning module 20 through the stopper 311. By providing the first base stopper 31, the placement position of the base module can be quickly determined according to the component positioning module 20. The two second stoppers 32 are respectively arranged on both sides of the base sliding groove 33, and are partially located above the sliding groove 33. The groove wall of the sliding groove 33 and the second stopper 32 can limit the movement of the sliding module 50 in a direction perpendicular to the first sliding direction A, so that the insertion portion 625 in the expansion module 60 thereon can be smoothly inserted between the two first pins 11 and 12.

[0087] In order to prevent the expansion module 60 from being displaced in a direction perpendicular to the first sliding direction A during the movement of the expansion module 60 toward the component positioning module 20, a U-shaped stopper 53 (such as Figure 3 , Figure 3 ). The U-shaped stopper 53 is fixedly disposed on the sliding body. A sliding channel is formed between the U-shaped stopper 53 and the sliding body. The U-shaped stopper 53 and the sliding body can limit the movement of the expansion module 60 in a direction perpendicular to the first sliding direction A. In this way, the sliding module can only move in the first sliding direction and the opposite direction thereof, so as to further ensure that the insertion portion can be accurately inserted between the two first pins of the electronic component.

[0088] Figure 6a It is a cross-sectional schematic diagram for illustrating the electronic component pin processing device of the present invention in one state. Figure 6b It is a cross-sectional schematic diagram for explaining the electronic component pin processing device of the present invention in another state. In the first sliding direction A, the sliding area 67 includes a first area 671 and a second area 672 in sequence.

[0089] Figure 6a In the electronic component pin processing device shown, the insertion portion 625 of the outward expansion driving rod 62 has just extended into between the two first pins 11 and 12 of the electronic component 10 , and the rotary driving member 54 is still located in the first area 671 . Figure 6b In the electronic component pin processing device shown in FIG. 1 , the rotary drive member 54 moves to the second area 672. Figure 6a-6bAs shown, when the rotary drive member 54 moves from the first area 671 to the second area 672, the rotary drive member 54 can push the two expansion drive rods 62 to rotate around their corresponding rotation axes. During rotation, the insertion portion 625 abuts against the first pin and pushes the first pin to deform to achieve expansion.

[0090] In the first sliding direction A, the outward expansion driving rod 62 includes the first section of the driving rod, the second section of the driving rod 622, the third section of the driving rod 623 and the fourth section of the driving rod 624 in sequence. The first section of the driving rod is provided with a shaft mounting hole 621 for connecting the rotating shaft. A first area 671 is formed between the second section of the driving rod 622 and the second section of the driving rod 622 of another outward expansion driving rod 62. A second area 672 is formed between the third section of the driving rod 623 and the third section of the driving rod 623 of another outward expansion driving rod 62. The end of the fourth section 624 of the driving rod protrudes to form an insertion portion 625. A second elastic member 63 can be provided between the third section 623 of the driving rod or the fourth section 624 of the driving rod and the side plate of the outward expansion base 61 adjacent thereto. The outward expansion driving rod of the electronic component pin processing device can automatically reset after completing the outward expansion operation and leaving the component positioning module, so as to facilitate the next outward expansion operation. The first elastic member 52 and the second elastic member 63 can both be springs, and the third elastic member and the fourth elastic member described below can also be springs.

[0091] The first area 671 formed between the two driving rod second sections 622 can allow the rotation driving member 54 to move freely. The intersection of the driving rod second section 622 and the driving rod third section 623 can act on the rotation driving member 54 along the movement path of the rotation driving member 54 in the first sliding direction A, and under the push of the rotation driving member 54, the outward expansion driving rod 62 rotates around the rotation axis.

[0092] In order to control the distance between the two insertion portions 625 in the initial state so as to accurately insert the two first pins 11 and 12, the expansion module 60 is further provided with a drive rod limiting column 64. The drive rod limiting column 64 is provided between the two expansion drive rods 62, and its end is limited to the expansion base 61. Under the action of the second elastic member 63, the two expansion drive rods 62 can abut against the drive rod limiting column 64.

[0093] See also Figure 3 and Figure 6bThe component positioning module 20 includes a main body seat, two pin positioning blocks 21, a component positioning plate 22 and a working position. The pin positioning block 21 is an L-shaped plate, which is fixedly mounted on the main body seat. The ends of the two pin positioning blocks 21 are arranged opposite to each other, and the three pins of the two-color indicator light can be accommodated between the two ends. The component positioning plate 22 is arranged above the two pin positioning blocks 21, and a notch is arranged on the component positioning plate 22, which is located above the area between the ends of the two pin positioning blocks 21. The two pin positioning blocks 21 and the component positioning plate 22 cooperate to form the working position of the electronic component 10. During operation, the head of the electronic component 10 is clamped by a tool and transported to the working position. At this time, the three pins of the electronic component 10 are located between the two pin positioning blocks 21, and the head of the electronic component 10 is located above the component positioning plate 22. An insertion portion 625 is inserted between the first pin 11 and the second pin 13, and the other insertion portion 625 is inserted between the first pin 12 and the second pin 13. The insertion portion 625 moves toward the adjacent pin positioning block 21 under the action of the rotating driving member 54, so as to drive the adjacent first pin to deform outward and finally abut against the pin positioning block 21. The distance between the two pin positioning blocks 21 determines the maximum distance between the two first pins 11 and 12 after expansion. The distance between the two pin positioning blocks 21 can be adjusted as needed.

[0094] In order to avoid damaging the first pins 11 and 12 of the electronic component 10 during the expansion process, an expansion positioning member 65 can be provided on the expansion module 60. The expansion positioning member 65 is fixedly mounted on the expansion base 61, and protrudes toward the component positioning module 20 to form a positioning protrusion 651. The end surface of the positioning protrusion 651 facing the component positioning module 20 is a plane. When the expansion module 60 moves to the component positioning module 20, the end surface of the positioning protrusion 651 can abut against the pins of the electronic component 10, and cooperate with the inner wall of the notch of the component positioning plate 22 to clamp the pins of the electronic component 10 to prevent the electronic component from being pulled during the expansion process. In addition, the positioning protrusion 651 can also control the depth of the insertion portion 625 after the pin is inserted.

[0095] The present application also provides an electronic component pin processing system, which includes any of the electronic component pin processing devices described above and a pin forming device.

[0096] Figure 7 It is a schematic structural diagram for illustrating the pin forming device of the invention.

[0097] like Figure 7As shown, the pin forming device includes a first support seat 80 and a second support seat 73, which are used to process the pins of the electronic components. During processing, the first support seat 80 and the second support seat 73 cooperate with each other to squeeze the pins of the electronic components, so as to form the pins of the electronic components into a desired shape, so that the height of the electronic component pins on the circuit board, the position between the pins, the angle and length of the pin bending meet the design requirements of the integrated circuit board. During processing, the head of the electronic component can be clamped by an auxiliary device and placed in a position adjacent to the first support seat 80. In addition, the distance between the head of the electronic component and the first support seat 80 is controlled by the auxiliary device to ensure the consistency of the forming of the pins of the batch of electronic components. For example, the auxiliary device can be controlled to make the head of the electronic component abut against the first support seat 80, or the auxiliary device can be controlled to clamp a specific position of the electronic component, and the auxiliary device can be controlled to hover at a specific height of the first support seat 80, and other methods can also be used.

[0098] The first support seat 80 of the pin forming device includes a forming support portion 81 , and a forming structure is disposed on the forming support portion 81 .

[0099] The second support seat 73 is fixedly provided with a slider stopper 76 and a cutting block 7424, wherein the cutting block 7424 is provided between the second support seat 73 and the slider stopper 76, and a cutting portion 741 is provided on the surface of the cutting block 7424 facing the first support seat 80. Specifically, the slider stopper 76 and the second support seat 73 can be fixed on two surfaces of the cutting block 7424 that are away from each other by welding; or the slider stopper 76, the cutting block 7424 and the second support seat 73 can be fixed together by screws that pass through the screws in sequence.

[0100] like Figure 7 As shown, the slider stopper 76 is U-shaped as a whole, and a slider sliding groove 761 is provided thereon. The slider sliding groove 761 extends along the second sliding direction B. A molded slider 75 is provided in the slider sliding groove 761, one end of the molded slider 75 is located in the slider sliding groove 761, and the other end extends out of the slider sliding groove 761. One end of the molded slider 75 extending out of the slider sliding groove 761 faces the first support seat 80, and a molding structure that matches the molding structure of the molding support portion 81 is provided thereon. A third elastic member 77 is provided between the end of the molded slider 75 that is away from the first support seat 80 and the slider stopper 76.

[0101] When the second support seat 73 is driven to move toward the first support seat 80 along the second sliding direction B, the molding slider 75 first hits the pin located at the molding support portion 81 and presses it onto the first support seat 80; as the second support seat 73 continues to move toward the first support seat 80, the third elastic member 77 is compressed to provide the molding slider 75 with a force along the second sliding direction B; the force gradually increases as the second support seat 73 continues to move toward the first support seat 80, so that the molding slider 75 cooperates with the first support seat 80 to squeeze the pin, thereby forming the pin of the electronic component 10 through the molding structure; the second support seat 73 further moves toward the first support seat 80 along the second sliding direction B, and the cutting block 7424 continues to move relative to the molding slider 75 along the second sliding direction B driven by the second support seat 73, and its cutting knife portion 741 abuts against the pin and moves further to cut off the pin. Therefore, the pin forming device can automatically process the pins of electronic components to meet the design requirements of the integrated circuit board, and its structure is simple. Only one device is needed to form and cut the pins of electronic components in one work process, and the processing efficiency is high.

[0102] The pin forming device may further include a mounting base 71 and a mounting frame 72. One end of the mounting frame 72 is fixedly connected to the mounting base 71. A second adjusting rod 722 is provided on the mounting frame 72, and the second adjusting rod 722 is a screw rod, which extends along the extension direction C of the pin. Among them, a mounting portion is provided at the end of the second support seat 73 away from the first support seat 80, and the mounting portion can extend into the mounting frame 72 and be screwed to the second adjusting rod 722. A first adjusting rod 721 is also provided on the mounting portion, and the first adjusting rod 721 is a screw rod, and its end can lock the second support seat 73 on the mounting frame 72. When in use, first extend the mounting portion of the second support seat 73 into the mounting frame 72, then install the second adjusting rod 722, pass one end of it through the mounting portion and install it on the mounting frame 72. Since the mounting portion and the second adjusting rod 722 are screwed together by threads, the height of the second support seat 73 can be adjusted by rotating the head of the second adjusting rod 722; then install the first adjusting rod 721 to the mounting portion of the second support seat 73, tighten the first adjusting rod 721, and the mounting frame 72 can be clamped together by the head of the first adjusting rod 721 and the main structure of the second support seat 73 to lock the second support seat 73 on the mounting frame 72.

[0103] Figure 8 It is a schematic structural diagram for illustrating a partial structure of the pin forming device of the invention. Fig. 9 It is a schematic structural diagram for illustrating a partial structure of the pin forming device of the invention. Fig. 91 shows the electronic component 10 after the forming and cutting process. Each of the two first pins is provided with a bending portion, and the second pin is provided with a vertical section, a bending section, and a vertical section in sequence from the fixed end to the free end.

[0104] like Figure 8 , Fig. 9 As shown, the first support seat 80 has a first limiting rib 811, 812 protruding from the plane facing the forming slider 75 of the forming support portion 81. The extension direction of the first limiting rib 811, 812 is perpendicular to the second sliding direction B shown and the extension direction C of the pin of the electronic component 10. The forming structure on the forming slider 75 includes first limiting grooves 751, 752 matching the first limiting rib 811, 812. When the second support seat 73 moves along the second sliding direction B relative to the first support seat 80, the first limiting rib 811, 812 can extend into the first limiting grooves 751, 752, and cooperate with the first limiting grooves 751, 752 to bend the portion of the pin located at the first limiting grooves 751, 752. The pin portion above and below the bending portion remains straight due to abutting against the plane of the forming support portion 81 and the forming slider 75. Therefore, by setting the first limiting ridge and the first limiting groove, a bending portion can be set on the first pin. The bending end determines the installation height of the pin of the electronic component on the circuit board. The pin forming device can ensure that the installation height of the first pins 11 and 12 is uniform and meets the requirements.

[0105] like Figure 8 , Fig. 9 As shown, a second limiting groove 813 is also provided on the plane where the first limiting ridges 811 and 812 are located. A first supporting surface and a second limiting inclined surface 8131 are provided in the second limiting groove 813. The first supporting surface is perpendicular to the second sliding direction B, and the angle between the second limiting inclined surface 8131 and the first supporting surface is greater than 90 degrees and faces the free end of the pin in the extension direction C of the pin. The molding structure of the molding slider 75 also includes a second limiting protrusion 753 that matches the second limiting groove 813. The cross section of the second limiting protrusion 753 that is perpendicular to the extension direction of the first limiting grooves 751 and 752 is in the shape of a right-angle step. The second limiting protrusion 753 is provided with a second supporting surface that matches the first supporting surface and a first limiting inclined surface 7531 that matches the second limiting inclined surface 8131. Therefore, by providing the second limiting groove and the second limiting convex portion, the second pin can be bent so that the second pin forms a "first straight section-bent section-second straight section" structure from the head of the electronic component, and the pin forming device can ensure that the installation height of the second pin 13 is uniform and meets the requirements. Through this device, the bending portion of the first pin of the electronic component and the bent section of the middle pin (i.e., the second pin 13) can be formed at the same time, thereby improving production efficiency.

[0106] Furthermore, in order to ensure that the installation height of the first pins 11 and 12 is the same as the installation height of the second pin 13, in the extension direction C of the pin, the edge formed by the intersection of the second support surface and the second limiting inclined surface 8131 and the end of the first limiting groove 751 and 752 facing the free end of the pin can be set to be at the same height. Therefore, the bending point between the "bending section-second straight section" on the second pin 13 is consistent with the height of the end of the bending portion on the first pin 11 and 12 close to the free end of the pin. The pin forming device of the present invention can make the installation height of the second pin consistent with the installation height of the first pin.

[0107] like Figure 7 , Figure 8 As shown, the slider stopper 76 is further provided with a slider stopper groove 762, and the molding slider 75 is further provided with a slider stopper portion 754. The slider stopper portion 754 is at least partially provided in the slider stopper groove 762, and when the second support seat 73 moves relative to the first support seat 80, the slider stopper portion 754 can slide in the slider stopper groove 762 along the second sliding direction B. When the molding slider 75 leaves the molding support portion 81, the slider stopper portion 754 can abut against the surface of the slider stopper groove 762 close to the molding support portion 81 to prevent the molding slider 75 from falling out of the slider stopper 76.

[0108] After completing the one-time forming and cutting process, in order to enable the second support seat 73 to quickly return to its initial position, a fourth elastic member may be provided between the first support seat 80 and the second support seat 73. Figure 7 , Figure 8 As shown, a support seat limiting portion 82 is provided on the first support seat 80, and a support seat receiving groove 731 is provided on the second support seat 73. When the first support seat 80 and the second support seat 73 move relative to each other, the end of the support seat limiting portion 82 is received in the support seat receiving groove 731, and a fourth elastic member is further provided between the first support seat 80 and the second support seat 73.

[0109] The present invention also provides an electronic component pin processing method, which is applied to the electronic component pin processing system of any of the above embodiments, wherein the electronic component is a two-color indicator light, and the electronic component pin processing method comprises:

[0110] Step 1: Shape the pins of the electronic component 10 so that the two first pins 11 and 12 and the third pin 13 are kept in the same plane.

[0111] Step 2: The two first pins 11 and 12 are expanded outwardly by an electronic component pin processing device to form first bending sections 112 and 122. Expanding the first pins outwardly is beneficial to subsequent molding and ensures the insertion size.

[0112] Step 3: Check the polarity of the electronic components. Use the color of the two-color indicator light to identify the polarity of the two-color indicator light.

[0113] Step 4: Using a pin forming device, the bent portions 111 and 121 are formed on the first pins 11 and 12 , and the second bent section 131 is formed on the third pin 13 .

[0114] The processing method can automatically complete the entire processing flow of the electronic component pins (including shaping, expansion, forming, and cutting), which not only improves the production efficiency but also ensures that the polarity of the processed electronic components meets the requirements.

[0115] In order to improve the yield rate of electronic components after processing, step 3 may further include: if the polarity is incorrect, the electronic component is rotated 180° and the polarity of the electronic component is checked again. For example, using the characteristics of the yellow LED light, the voltage is high and the red LED light is low. When the yellow LED light is on, the voltage is high and the red LED light is low. When the red LED light is on, the voltage is low. Then the LED light is installed 180 degrees to ensure that the polarity of the electronic component is correct and consistent after molding.
