DETAILED DESCRIPTION

[0045] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] The core of the present invention is to provide an electronic component pin bending system, which can improve the pin bending efficiency.

[0047] The electronic component pin bending system provided by the present invention, in the specific embodiment 1, please refer to Figures 3 to 16 , including a bending device 1, which is used to implement the pin bending process.

[0048] Among them, the bending device 1 includes a first positioning mechanism 13 and a bending drive mechanism. The first positioning mechanism 13 is used to position the main body 21 of the electronic component 2, and in the positioned state, the pins 22 of the electronic component 2 can extend out of the side of the first positioning mechanism 13, and the bending drive mechanism can press down or press up to bend the pins 22 of the electronic component 2 in the positioned state.

[0049] Among them, Figure 1 and Figure 2 As shown, the electronic component 2 is a chip, specifically a vehicle-mounted sensor chip, more specifically a TO94 packaged product, and the main body 21 of the electronic component 2 is a plastic package of the chip. In other embodiments, other electronic components 2 may also be used.

[0050] In this embodiment, through the setting of the bending device 1, the pins 22 can be automatically bent according to the bending direction requirements of each pin 22. During the bending process, the electronic component 2 is installed on the corresponding first positioning mechanism 13 and positioned. The corresponding pin 22 is pushed to bend and deformed with the help of the bending drive mechanism, which can improve the bending efficiency of the pin 22.

[0051] Furthermore, the two bending devices 1 in the electronic component pin bending system are respectively a first bending device 11 and a second bending device 12 arranged in parallel. The bending drive mechanism in the first bending device 11 is used to press down the pin 22 of the electronic component 2 in a bent and positioned state, and the bending drive mechanism in the second bending device 12 is used to press up the pin 22 of the electronic component 2 in a bent and positioned state, so that the pin 22 can be bent in different directions by the two bending devices 1.

[0052] Among them, in this embodiment, Fig.16 As shown, four bending devices 1 are provided, namely, two first bending devices 11 and two second bending devices 12, wherein, starting one of the first bending devices 11 and one of the second bending devices 12 can realize the bending of the pins of the electronic components with L-shaped pins; starting two first bending devices 11 and two second bending devices 12 can realize the bending of the pins of the electronic components with V-shaped pins. Of course, in other embodiments, only one or more than two can be provided according to the bending requirements of the pins 22.

[0053] Further, the bending drive mechanism includes a positioning knife 14, a bending drive, and a bending knife 15 connected to the bending drive. The positioning knife 14 is arranged above the first positioning mechanism 13 or arranged in parallel on the side of the first positioning mechanism 13. The bending drive can drive the bending knife 15 to move toward the side of the positioning knife 14 to press the pin 22 of the electronic component 2.

[0054] Among them, the positioning knife 14 is used to position the bent portion of the pin 22, and the shape and angle of the positioning knife 14 can be adaptively set according to the bending requirements of the pin 22, such as Figure 7 As shown, the top of the side surface of the positioning knife 14 for positioning the bending part of the pin 22 has a chamfer R, and the side surface is inclined relative to the horizontal plane and has an angle θ1. In addition, the size of the bending knife 1 can also be set according to the bending requirements of the pin 22, such as Figure 8 As shown, its side surface includes an angle θ2 relative to the horizontal plane.

[0055] The movement direction of the bending knife 15 driven by the bending driver may be a straight line, an arc or a broken line, which can be set according to needs, as long as the pin 22 can be pressed to the side of the positioning knife 14 to achieve bending.

[0056] Among them, in the first bending device 11: Fig.11 As shown, the positioning knife 14 is a first positioning knife 141, the bending knife 15 is a first bending knife 151, the bending driver is a first bending driver, and the first positioning knife 141 is fixed to the side of the first positioning mechanism 13; in the second bending device 12: Fig.13As shown, the positioning knife 14 is the second positioning knife 142 , the bending knife 15 is the second bending knife 152 , the bending driver is the second bending driver, and the second positioning knife 142 is fixed above the second positioning mechanism 51 .

[0057] for Figure 1 The L-shaped pin shown in the figure is bent and formed, and the two middle pins 22 are as follows: Figures 7 to 11 As shown, the position on the pin 22 that needs to be bent is aligned above the first side surface 1411 of the first positioning knife 141, as shown in FIG. Fig. 9 As shown, the first bending knife 151 is driven by the first bending driver to first press down the portion of the pin 22 that protrudes out of the first side surface 1411 of the first positioning knife 141, and then Fig.10 As shown, the first bending knife 151 moves closer to the first side surface 1411 of the first positioning knife 141 ( Fig.10 The pin 22 moves leftward in the middle of the first side surface 1411 so that the turning point of the pin 22 is in contact with the top of the first side surface 1411 and is accurately bent.

[0058] Afterwards, for the two pins 22 on both sides, specifically Fig.13 and Fig.14 As shown, the position on the pin 22 that needs to be bent is aligned below the second side surface 1421 of the second positioning knife 142, and the second bending knife 152, driven by the second bending driver, first presses the part of the pin 22 that protrudes out of the second side surface 1421 of the second positioning knife 142, and then the second bending knife 152 moves closer to the second side surface 1421 of the second positioning knife 142, so that the turning point of the pin 22 fits the top of the second side surface 1421 and is accurately bent.

[0059] For Figure 2 The V-shaped pins shown have two turns on each pin 22. Fig.16 In the system shown in , each first bending device 11 and each second bending device 12 are respectively used to form a turning point, wherein the pin 22 that needs to be pressed down passes through the two first bending devices 11 in sequence to realize two downward turning points in two steps, and the pin 22 that needs to be pressed up passes through the two second bending devices 12 in sequence to realize two upward turning points in two steps. Of course, in other embodiments, the two turning points of the pin 22 can be realized in one first bending device 11 or one second bending device 12. At this time, the top surface of the positioning knife 14 can be provided with a bending edge at the joint with the side surface and the middle part of the side surface, that is, two bending edges are formed, which are respectively used to locate the two turning points of the V-shaped pin. The first bending knife 151 and the second bending knife 152 can be evenly divided into two actions to make the pin 22 bend once at each of the two bending edges to form a V shape.

[0060] In this embodiment, by providing a positioning knife 14 in the bending device 1, the turning position of the pin 22 can be accurately defined, the bending accuracy can be improved, a higher yield can be achieved, and the maximum economic value can be obtained.

[0061] Furthermore, the electronic component pin bending system further comprises a feeding device 3 arranged in parallel with the bending device 1, such as Figure 2 As shown, it is applied to the loading process, and is used to provide the electronic component 2 whose pin 22 is to be bent. The loading device 3 includes a tray module 31 (i.e., a Tray module) and a loading robot 32. The tray module 31 has a plurality of material troughs 311 arranged in parallel to place the electronic components 2 respectively. The loading robot 32 is used to take out the electronic components 2 from the material troughs 311 and transfer them to a set device. Preferably, a visual recognition component is provided on the loading robot 32 to identify the electronic components 2. In addition, the loading robot 32 picks up the material through the loading nozzle on it. In other embodiments, the material can also be picked up by setting a fixture.

[0062] In this embodiment, the feeding method of the electronic components 2 is that the material tray module 31 feeds the bending device 1 or other devices, and different electronic components 2 can be placed in different material slots 311. The electronic components 2 are separated from each other by the material slots 311 in the material tray module 31, so as to avoid mutual squeezing and crossing between the pins 22 of the electronic components 2, and to avoid damage to the pins 22 before bending to the greatest extent. In addition, the loading robot 32 will first identify the chip position by vision, and accurately locate the specific structure on the electronic component 2, such as the plastic package of the chip, and then the electronic component 2 will be sucked up by the equipped loading robot 32, which can improve the accuracy and efficiency of loading.

[0063] Furthermore, if Figure 5 , Figure 6 and Fig.16 As shown, the electronic component pin bending system also includes a cutting device 5 arranged in parallel with the bending device 1, which is used to implement the pin cutting process. For the electronic component 2 whose pin 22 length needs to be adjusted, the pin 22 is cut to the length required by the customer, and the cutting device 5 is used to cut the pin 22. This process can be performed before the pin bending process, such as Fig.16 As shown, specifically, the cutting device 5 and each bending device 1 can be arranged linearly, and the cutting device 5 is arranged at one end. Of course, for the electronic component 2 that does not need to adjust the length of the pin 22, this process can also be omitted.

[0064] The cutting device 5 includes a second positioning mechanism 51, a cutting support table 52, a cutter driver and a cutter 53. As required, the loading robot 32 can place the electronic component 2 taken on the first positioning mechanism 13 of the bending device 1 or the second positioning mechanism 51 of the cutting device 5. The cutting support table 52 is fixed to the side of the second positioning mechanism 51. The second positioning mechanism 51 is used to position the body 21 of the electronic component 2, and in the positioned state, the pins 22 of the electronic component 2 can extend out of the side of the cutting support table 52. The cutter 53 is connected to the cutter driver so that under the drive of the cutter driver, the cutter 53 can cut off the part of the pin 22 extending out of the side of the cutting support table 52.

[0065] like Figure 5 As shown, after the main body 21 of the electronic component 2 is fixed by the second positioning mechanism 51, the portion of the pin 22 close to the main body 21 rests on the second positioning mechanism 51 and the cutting support table 52, and the remaining portion extends out from the third side 521 of the cutting support table 52. The position on the pin 22 that needs to be cut is aligned with the top of the third side 521 of the cutting support table 52. The cutter 53 can be driven by the cutter driver to cut off the portion of the pin 22 extending out of the third side 521 along the third side 521, thereby realizing automatic adjustment of the length of the pin 22.

[0066] In addition, a waste collection box 54 is also provided in the cutting device 5 , which is located below the cutter 53 and can directly receive the waste pins 22 cut by the cutter 53 .

[0067] Furthermore, the electronic component pin bending system also includes a product inspection device 4 arranged in parallel with the bending device 1, which is used in the inspection process to detect the qualification of the electronic component 2. This is performed after the pin bending process, and unusable electronic components 2 can be disposed of in time.

[0068] like Fig.15As shown, the product inspection device 4 includes a third positioning mechanism 42 and a test assembly. The third positioning mechanism 42 is used to position the main body 21 of the electronic component 2, and in the positioned state, the test assembly can detect whether the pin 22 meets the preset standard. The preset standard can be set according to the structure of the test assembly and the content to be measured: for example, the test assembly performs AOI (Auto Optical Inspection) test on the size of the electronic component 2 through visual inspection, and accordingly, the preset standard is the preset standard size range of the pin 22, so as to select the electronic component 2 whose size of the pin 22 is processed and formed to meet the customer's requirements, and finally enter the tape for shipment; or, the test assembly can be used for OS (Open-Short) + Leakage test, and the test assembly can specifically include an OS test probe 41 to detect the internal situation of the pin 22 and select the electronic component 2 whose internal structure is not damaged during the pin 22 molding process.

[0069] Furthermore, the first positioning mechanism 13 , the second positioning mechanism 51 , and the third positioning mechanism 42 may adopt the same clamping positioning mechanism 6 .

[0070] like Figure 5 , Fig.11 and Fig.13 As shown, the clamping and positioning mechanism 6 includes a positioning support platform 61, a positioning stop bar 62, a positioning block 63 and a positioning block driver 610. The positioning stop bar 62 is fixed above one side of the positioning support platform 61, and the positioning block 63 is slidably connected above the positioning support platform 61. The positioning block driver 610 can be a cylinder, and in other embodiments, it can also be a motor. The positioning block 63 can move toward the positioning stop bar 62 under the drive of the positioning block driver 610, so as to clamp and position the main body 21 of the electronic component 2 through the positioning stop bar 62 and the positioning block 63. Optionally, a guide rail 65 can be set on the positioning support platform 61, and the positioning block 63 is slidably connected to the guide rail 65 to linearly guide the positioning block 63.

[0071] In this embodiment, the clamping and positioning mechanism 6 can be adapted to the positioning of the main body 21 of various types of electronic components 2 by clamping and positioning. Figure 5 As shown, the chip is placed on the positioning support platform 61, and the positioning block 63 moves toward the chip. When the positioning block 63 moves into place, the positioning block 63 and the positioning stop bar 62 cooperate to clamp the plastic package of the chip, ensuring that the chip is reliably fixed.

[0072] Furthermore, if Figure 5 As shown, the clamping and positioning mechanism 6 also includes a positioning suction nozzle 64 disposed on the positioning support platform 61, specifically a vacuum suction nozzle, to suck the main body 21 of the electronic component 2 downward to ensure the stability of the placement of the electronic component 2.

[0073] Furthermore, if Figure 5 , Fig.11 and Fig.13 As shown, the first positioning groove 631 facing the positioning stop bar 62 is provided on the positioning block 63 to engage with the positioning stop bar 62 to position the main body 21 of the electronic component 2. Specifically, the first positioning groove 631 of the positioning block 63 is arranged close to the positioning stop bar 62 to conform to the main body 21 of the electronic component 2, which can ensure that each time the electronic component is installed, it is located at a fixed position on the positioning support platform 61. Optionally, the first positioning groove 631 is provided on the positioning block 63 in the first positioning mechanism 13 and the second positioning mechanism 51. Of course, in other embodiments or other clamping and positioning mechanisms 6, the second positioning groove facing the positioning block 63 can also be provided on the positioning stop bar 62 to engage with the positioning block 63 to position the main body 21 of the electronic component 2.

[0074] Furthermore, if Figure 4 As shown, the clamping and positioning mechanism 6 may further include a positioning clamping claw driver 69 and a positioning clamping claw 68 connected to the positioning clamping claw driver, which can clamp the main body 21 of the electronic component 2 in a direction perpendicular to the movement of the positioning block 63 to cooperate with the positioning block 63 and the positioning stop bar 62 to fully position the main body 21 of the electronic component 2, thereby further increasing the types of electronic components 2 that can be positioned. Specifically, Fig.15 As shown, the third positioning mechanism 42 is not provided with the first positioning groove 631 and the second positioning groove, but is provided with the above-mentioned positioning jaw driver 69 and positioning jaw 68 to comprehensively position the main body 21 of the electronic component 2 .

[0075] Further, the positioning blocks 63 in the first positioning mechanism 13, the second positioning mechanism 51 and the third positioning mechanism 42 can be driven by the same positioning block driver 610. Optionally, in order to ensure the stability of the movement of each positioning block 63, as Figure 4 As shown, each positioning support platform 61 can be provided with a sliding block, on which a sliding hole is provided to slidably connect the positioning rod 66 , and a buffer spring 67 is sleeved on the positioning rod 66 , and the buffer spring 67 is pressed between the positioning block 63 and the positioning rod 66 .

[0076] Of course, in other embodiments, the first positioning mechanism 13, the second positioning mechanism 51, and the third positioning mechanism 42 may also adopt other forms of positioning structures for positioning. For example, a positioning platform is directly set up, and a positioning groove matching the main body 21 of the electronic component 2 is set on it, and the main body 21 of the electronic component 2 is directly placed in the positioning groove to achieve positioning.

[0077] The electronic component pin bending system in this embodiment is applied to the pin bending of L-shaped pin chips (BV products). The working principle includes: the loading robot 32 sucks the chip from the material slot 311 of the material tray module 31, and transports it to the second positioning mechanism 51 of the cutting device 5 to accurately position the chip. The positioning method is that after the chip is placed in the corresponding position, the end of the plastic package body away from the pin 22 is pushed by the positioning block 63 to limit the chip to a set position. After the product is positioned, the part of the pin 22 that exceeds the set size is cut off by the up and down movement of the cutter 53, so that the pin 22 of the chip is cut into the length required by the customer. After that, the electronic component 2 is placed on the first positioning mechanism 13 of the first bending device 11, and the two middle pins 22 are bent first. Specifically, the pin is formed by the two-step movement of the second bending knife 152: the first step is the downward movement, and the second step is the left and right movement. The two pins 22 can be bent separately or at the same time. Afterwards, the electronic component 2 is placed on the first positioning mechanism 13 of the second bending device 12 to bend the two pins 22 on both sides. The principle is the same as that of the two middle pins, except that the pressing action is changed to the pushing action of the second bending knife 152.

[0078] The electronic component pin bending system in this embodiment has the following advantages: the tray feeding mode can reduce the yield loss by more than 10%; it has a unique bending process. When bending the pins, different pins 22 are bent by separate process angle bending modes, which can improve the stability of the equipment and can independently debug and control the size of each pin 22.

[0079] It should be noted that when an element is referred to as "fixed" to another element, it may be directly on the other element or there may be an element in the middle. When an element is considered to be "connected" to another element, it may be directly connected to the other element or there may be an element in the middle at the same time. In addition, in the description of the present invention, unless otherwise specified, "multiple", "multiple roots", "multiple groups" mean two or more.
