In this embodiment, the present invention is installed between the insertion machine and the material tray, the feed end of the guide trough 11 is connected to the material tray, and the discharge end of the guide trough 11 is connected to the insertion machine. Before the insertion machine inserts the component 62, the present invention needs to bend the component 62 on the component strip 6 to a set angle (such as Figure 1As shown), during the process of the insertion machine inserting the bent component 62 into the external PCB board, the insertion machine pulls the component tape 6 to move along the material guide slot 11, and the component tape 6 includes a connecting tape 61 and multiple components 62. The connecting tape 61 is provided with multiple tape holes 64. The multiple components 62 are arranged along the length direction of the connecting tape 61. The pins 63 of the components 62 are connected to the connecting tape 61, and each tape hole 64 is located between two adjacent components 62.

[0026] In actual application, the material tray supplies the component material strip 6 to the material guide track 1, so that the component material strip 6 passes through the material guide slot 11 and moves along the length direction of the material guide slot 11. When each component 62 on the component material strip 6 moves between the bending piece 22 and the bending abutment plate 4, the bending driver drives the bending piece 22 to move close to the bending abutment plate 4 until the bending piece 22 cooperates with the bending abutment plate 4 to bend the pin 63 of the component 62. When the bent component 62 moves to the bottom of the pressing mechanism 3 When the bending device 62 is moved, the pressing mechanism 3 presses down the head of the bent component 62, so that the component 62 is bent to a set angle, so as to ensure that the bending angle of each component 62 is consistent, thereby improving the quality of the bending; wherein, the limiting strip 5 protrudes into the guide groove 11 and contacts the top of the connecting strip 61, and the limiting strip 5 limits the connecting strip 61, thereby limiting the component strip 6, and preventing the component strip 6 from deviating upward or swinging during the movement, further improving the quality of the bent component 62. The bending device has a simple and compact structure, and automatically bends the components 62 on the component strip 6, thereby improving the efficiency of bending the components 62 and reducing the cost of bending the components 62. The limiting strip 5 limits the component strip 6, and the pressing mechanism 3 presses down the bent component 62, so that the bending quality is good, thereby improving the insertion quality of the component 62 by the insertion machine.

[0027] In this embodiment, the feeding end of the guide track 1 is provided with a supporting assembly 7 for pressing the component strip 6 against the limiting strip 5. The supporting assembly 7 and the bending mechanism 2 are located on the same side of the guide groove 11. The supporting assembly 7 includes a supporting member 71 rotatably arranged on the guide track 1, a fixed seat 72 installed on the guide track 1, and a first elastic member arranged between one side of the supporting member 71 and the fixed seat 72. The other side of the supporting member 71 is used to press the component strip 6 against the limiting strip 5.

[0028] In actual applications, the first elastic member provides an elastic force toward the limiting strip 5 to the abutment member 71, so that the abutment member 71 always presses the component strip 6 against the limiting strip 5, thereby enabling the component strip 6 to move close to the limiting strip 5, and the limiting strip 5 can continuously abut the top of the connecting strip 61 of the component strip 6, thereby improving the stability of the movement of the component strip 6.

[0029] In this embodiment, the material guide track 1 is provided with a limiting assembly, and the material guide track 1 is provided with an installation groove 12 which is connected with the material guide groove 11 and is used to install the limiting assembly, which not only facilitates the assembly of the limiting assembly, but also makes the structure between the limiting assembly and the material guide track 1 compact; the limiting assembly includes a first limiting member 81 and a second elastic member 82, the second elastic member 82 is arranged between the first limiting member 81 and the side wall of the installation groove 12, the first limiting member 81 is provided with a first limiting block 83 protruding into the material guide groove 11, the first limiting block 83 is provided with a limiting inclined surface 84, and the first limiting member 81 is rotatably arranged in the installation groove 12.

[0030] During assembly, the elastic force of the second elastic member 82 enables the first limiting member 81 to be stably installed in the mounting groove 12 and to be able to rotate in the mounting groove 12; in actual application, during the process of the bending mechanism 2 bending the component 62, the first limiting block 83 of the first limiting member 81 protrudes into the material guide groove 11, and the first limiting block 83 protrudes to the material strip hole 64 of the connecting strip 61, so that the limiting inclined surface 84 contacts the hole wall of the material strip hole 64, thereby limiting the component material strip 6, ensuring the position accuracy and stability of the component material strip 6, avoiding the problem of backward movement of the component material strip 6, and thereby improving the quality of the bent component 62. When the component strip 6 moves, the hole wall of the strip hole 64 contacts the limiting slope 84, so that the first limiting member 81 is subjected to an extrusion force to rotate into the installation groove 12, thereby causing the first limiting member 81 to rotate into the installation groove 12. The first limiting block 83 is separated from the strip hole 64 to realize the movement of the component strip 6. Repeat the above operation to realize the intermittent movement of the component strip 6.

[0031] Specifically, a guide rod is provided at one end of the first position-limiting member 81, the material guide track 1 is provided with a guide hole connected to the mounting groove 12, and the second elastic member 82 is a spring, one end of the spring is installed in the guide hole, and the other end of the spring is sleeved outside the guide rod. This structural design facilitates the installation of the position-limiting component in the mounting groove 12 of the material guide track 1, and plays a role in positioning the second elastic member 82, ensuring the stability of the second elastic member 82, and preventing the second elastic member 82 from being bent or tilted under pressure.

[0032] Specifically, the fixing seat 72 is provided with a limiting notch 73, and one side of the abutting member 71 protrudes into the limiting notch 73. The inner wall of the limiting notch 73 abuts against the abutting member 71, and the limiting notch 73 limits the abutting member 71 to prevent the abutting member 71 from swinging up and down when rotating, thereby improving the stability of the rotation of the abutting member 71.

[0033] Specifically, a handle 74 is provided on the top of the abutment member 71 . The addition of the handle 74 facilitates the operator to manually rotate the abutment member 71 , so as to place the component tape 6 in the material guide slot 11 or remove the component tape 6 from the material guide slot 11 .

[0034] Specifically, the feed end of the guide trough 11 is V-shaped, which guides the component tape 6 and facilitates the material tray to supply the component tape 6 into the guide trough 11, thereby improving the stability and efficiency of feeding.

[0035] Specifically, the first elastic member is a spring, the fixing seat 72 is provided with a fixing hole connected to the limiting notch 73, one end of the first elastic member is inserted into the fixing hole, and the other end of the first elastic member abuts against one side of the abutting member 71. The fixing hole is provided to facilitate the assembly of the first elastic member on the one hand, and to position the first elastic member on the other hand, thereby ensuring the stability of the first elastic member.

[0036] In this embodiment, a second stopper 51 is installed at the bottom of the bending member 22, and the second stopper 51 is used to abut against the connecting belt 61 of the component strip 6. When the bending member 22 cooperates with the bending abutment plate 4 to bend the component 62, the second stopper 51 abuts against the top of the connecting belt 61 of the component strip 6 to limit the component strip 6, thereby preventing the component strip 6 from deviating upward during the movement, ensuring that the bending mechanism 2 can normally bend the component 62, and improving the quality of the bent component 62.

[0037] Specifically, the bending member 22 is provided with a bending block 23, the bottom surface of the bending block 23 is higher than the top surface of the bending abutment plate 4; preferably, the bottom surface of the bending block 23 is higher than the top surface of the bending abutment plate 4, and the distance between the bottom surface of the bending block 23 and the top surface of the bending abutment plate 4 is equal to the diameter of the pin 63 of the component 62. This structural design improves the quality of the pin 63 of the bent component 62.

[0038] In this embodiment, the second limiting member 51 is provided with a plurality of second limiting blocks 52, and the bending abutting plate 4 is provided with a plurality of limiting holes 41 for accommodating the second limiting blocks 52, and the plurality of second limiting blocks 52 are provided in a one-to-one correspondence with the plurality of limiting holes 41. In the process of the bending member 22 bending the pins 63 of the component 62, the second limiting block 52 of the second limiting member 51 moves into the limiting hole 41, and the bottom surface of the second limiting block 52 abuts against the top of the connecting strip 61 of the component strip 6, so as to limit the component strip 6, prevent the component strip 6 from shifting upward during the movement, improve the position accuracy of the component strip 6, and further improve the quality of the bent component 62.

[0039] In this embodiment, the bending drive includes a bending cylinder 24 installed on the material guide track 1 and a reset assembly installed between the material guide track 1 and the bending member 22. The piston rod of the bending cylinder 24 is used to resist the end of the bending member 22 away from the bending abutment plate 4, and the reset assembly is used to drive the bending member 22 to reset; specifically, the reset assembly includes a connecting rod 25 installed on the bending member 22 and a third elastic member 26 connected to the connecting rod 25 and the material guide track 1.

[0040] In actual application, the piston rod of the bending cylinder 24 stretches and contacts the bending member 22 to move close to the bending abutment plate 4, and the bending member 22 drives the second stopper 51 to move synchronously until the bending of the component 62 is completed. At this time, the third elastic member 26 is stretched. When the piston rod of the bending cylinder 24 contracts, the third elastic member 26 drives the bending member 22 and the second stopper 51 to move away from the bending abutment plate 4 under the action of the rebound force, thereby resetting the bending member 22 and the second stopper 51. In this structural design, the piston rod of the bending cylinder 24 is non-fixedly connected to the bending member 22 and the second stopper 51, which is convenient for disassembly and assembly of the bending cylinder 24, the bending member 22 and the second stopper 51, and the disassembly and maintenance are convenient, which improves the disassembly and maintenance efficiency of the bending cylinder 24 and the bending member 22 and the second stopper 51.

[0041] Specifically, the two ends of the connecting rod 25 protrude from the two sides of the bending part 22, and the number of the third elastic members 26 is two, and the two third elastic members 26 are respectively located on the two sides of the bending part 22, and the third elastic member 26 is a tension spring, one end of which is connected to the material guide track 1, and the other end of the tension spring is connected to one side of the connecting rod 25. This structural design makes the bending part 22 evenly stressed, and improves the stability of the movement of the bending part 22.

[0042] In this embodiment, the guide rail 1 is equipped with a sensor 9 for detecting whether the pressed component 62 is qualified. The sensor 9 is electrically connected to the pressing mechanism 3, and the position of the sensor 9 is set corresponding to the position of the pressing mechanism 3. After the pressing mechanism 3 presses down the bent component 62, the sensor 9 detects the head of the pressed component 62. When the head of the bent component 62 is higher than the preset bending plane, the sensor 9 feeds back a signal to the pressing mechanism 3, so that the pressing mechanism 3 presses down the head of the component 62 again, until the sensor 9 detects that the head of the pressed component 62 is in the preset bending plane, proving that the bending of the component 62 is qualified. At this time, the sensor 9 feeds back a signal to the insertion machine, so that the insertion machine inserts the component 62 and drives the component strip 6 to move along the guide groove 11. By adding the sensor 9 to automatically detect the bent component 62, the bending consistency of the component 62 is ensured, and the bending quality of the component 62 is improved.

[0043] In this embodiment, the material guide rail 1 is provided with a height adjustment groove 13 connected to the material guide groove 11, and the bent abutment plate 4 is slidably set in the height adjustment groove 13. The bent abutment plate 4 is provided with a height adjustment hole 42, and a height adjustment piece is provided in the height adjustment hole 42. One end of the height adjustment piece is used to abut against the bottom wall of the height adjustment groove 13, and the bent abutment plate 4 is detachably connected to the material guide rail 1 via bolts.

[0044] Since the sizes of components 62 of different specifications are different, the bending parts and heights of the components 62 are also different, so it is necessary to adjust the height (bending position) of the bending abutment plate 4 on the guide rail 1. In this embodiment, the length of the bottom end of the height adjustment member protruding out of the height adjustment hole 42 is changed by adjusting the position of the height adjustment member in the height adjustment hole 42. The end of the height adjustment member contacts the guide rail 1, so that the bending abutment plate 4 moves up and down and slides in the height adjustment groove 13. After the bending position of the bending abutment plate 4 is adjusted, the bending abutment plate 4 is locked on the guide rail 1 by bolts to ensure the stability of the bending abutment plate 4, which can improve the quality of the bent components 62. When the length of the bottom end of the height adjustment member protruding out of the height adjustment hole 42 becomes shorter, the bending abutment member 71 moves down in the height adjustment groove 13, thereby lowering the bending position of the bending abutment member 71; otherwise, the bending position of the bending abutment member 71 is raised. This structural design can meet the needs of bending components 62 of different specifications, has good versatility and a wide range of applications.

[0045] Specifically, the height adjustment hole 42 is vertically arranged and passes through the bending abutment plate 4, the height adjustment hole 42 is a first threaded hole, and the height adjustment member is an adjusting screw, which is threadedly connected to the first threaded hole; for actual adjustment, it is only necessary to twist the adjusting screw so that the adjusting screw moves up and down in the first threaded hole, so as to adjust the bending position of the bending abutment plate 4, and the adjustment is convenient and quick.

[0046] The guide rail 1 is also provided with an adjustment hole 14 connected to the height adjustment slot 13, and a second threaded hole 43 connected to the adjustment hole 14 is provided on the side of the bending abutment plate 4 away from the bending member 22, and the threaded end of the bolt passes through the adjustment hole 14 and is threadedly connected to the second threaded hole 43. Preferably, the adjustment hole 14 is a waist-shaped hole, and the number of the second threaded holes 43 is multiple, and the multiple second threaded holes 43 are arranged vertically and along the long hole diameter direction of the waist-shaped hole.

[0047] When adjusting the bending position of the bending abutment plate 4, first twist the bolt so that the bolt loosens the guide rail 1 (the bolt does not lock the bending abutment plate 4 on the guide rail 1), and then adjust the height of the bending abutment plate 4 by adjusting the height adjustment member. At this time, the bolt moves up and down along the adjustment hole 14. After the bending abutment plate 4 is adjusted, twist the bolt again so that the bolt locks the bending abutment plate 4 on the guide rail 1. This structural design does not require the bolt to be completely removed to adjust the height of the bending abutment plate 4, and the adjustment is convenient and quick. Of course, according to the different heights of the bending abutment plate 4, the bolt is threadedly connected to the second bolt hole at the corresponding position.

[0048] In this embodiment, a plurality of adjusting gaskets are arranged between the bending member 22 and the material guiding track 1. Specifically, the adjusting gaskets are arranged between the bending member 22 and the second limiting member 51.

[0049] Since the components 62 of different specifications have different sizes, the bending positions and heights of the components 62 are also different, so it is necessary to adjust the height (bending position) of the bending member 22 on the guide track 1. In this embodiment, the height of the bending member 22 is changed by adding or removing adjusting gaskets, so that the bending member 22 can bend components 62 of different specifications, which has good versatility and a wide range of uses, reduces the cost of the bending components 62, and the structural design makes it flexible and convenient to adjust the height of the bending member 22. Of course, the number and thickness of the adjusting gaskets can be selected according to actual needs, and there can also be no adjusting gaskets.

[0050] In this embodiment, the pressing mechanism 3 includes a pressing seat 31 installed on the material guide track 1, a pressing driver 32 installed on the pressing seat 31 and a pressing member 33 installed on the output end of the pressing driver 32, and the pressing member 33 is located above the bending abutment plate 4.

[0051] In actual application, when the bent component 62 moves to the bottom of the pressing piece 33, the pressing driver 32 drives the pressing piece 33 to move close to the head of the bent component 62 until the pressing piece 33 presses the head of the component 62 down to a set position, thereby ensuring that the bending angle of each component 62 remains consistent and improving the quality of the bent component 62.

[0052] Specifically, the sensor 9 is electrically connected to the pressing driver 32, the pressing driver 32 is a cylinder, the pressing member 33 is mounted on the piston rod of the cylinder, and the pressing member 33 is a disc-shaped rubber member. The rubber member has a certain elasticity and plays a buffering role. The pressing member 33 is in flexible contact with the head of the component 62 and will not crush or emboss the head of the component 62.

[0053] Specifically, the lower pressure seat 31 includes a vertical adjustment plate 311, a transverse adjustment plate 312 and a longitudinal adjustment plate 313, the transverse adjustment plate 312 and the longitudinal adjustment plate 313 are both right-angled, the material guide track 1 is provided with a fixed threaded hole, one end of the vertical adjustment plate 311 is provided with a vertical adjustment groove connected to the fixed threaded hole, the other end of the vertical adjustment plate 311 is vertically arranged with a plurality of first fixing holes, the side of the transverse adjustment plate 312 is provided with a transverse adjustment groove for connecting with the first fixing hole, the top surface of the transverse adjustment plate 312 is provided with a plurality of second fixing holes, and the plurality of fixing holes are arranged transversely, the bottom surface of the longitudinal adjustment plate 313 is provided with a longitudinal adjustment groove connected to the second fixing hole, the length direction of the vertical adjustment groove, the length direction of the transverse adjustment groove and the length direction of the longitudinal adjustment groove are perpendicular to each other, and the vertical adjustment groove, the transverse adjustment groove and the longitudinal adjustment groove are all waist-shaped grooves. The lower pressing seat 31 of this structural design can adjust the position of the vertical adjustment plate 311 relative to the material guide track 1, the position of the transverse adjustment plate 312 relative to the vertical adjustment plate 311, and the position of the longitudinal adjustment plate 313 relative to the transverse adjustment plate 312 according to actual conditions, thereby adjusting the position of the lower pressing mechanism 3 (including: the height position of the lower pressing mechanism 3 relative to the top surface of the material guide track 1, the transverse position of the lower pressing mechanism 3 relative to the bending abutment plate 4, and the longitudinal position of the downward movement mechanism relative to the vertical adjustment plate 311).

[0054] Specifically, the material guide track 1 is provided with a slide groove 15 connected to the material guide groove 11, and the bending part 22 is slidably set in the slide groove 15, and the bending part 22 moves along the slide groove 15, thereby improving the stability of the movement of the bending part 22; the material guide track 1 is equipped with two limit plates 93, and the two limit plates 93 are arranged in parallel. The two limit plates 93 protrude from both sides of the slide groove 15 into the slide groove 15 and abut against the bending part 22. The two limit plates 93 limit the upper surface of the bending part 22 to prevent the bending part 22 from swinging upward.

[0055] Specifically, two opposite side walls of the slide groove 15 are recessed with limit grooves 16, and the limit grooves 16 pass through the side walls of the slide groove 15.
