Description

Technical Field

[0001] The present invention relates to a feeding device, and more particularly to a high-speed feeding device for diode processing. Background Art

[0002] During the process of approaching the end of the production of surface mount diodes, in order to enable the surface mount diodes to better complete subsequent processing and be easily packaged after production, the surface mount diodes are placed one by one at even intervals on a tape.

[0003] As Figure 1 shown, a notch is evenly formed at intervals on the tape, and this notch can just enable the surface mount diode to be stuck in this notch. After the surface mount diode is stuck, a tape is adhered to the bottom of the surface mount diode, so that the lead part of the surface mount diode is between the tape and the tape, thereby completing the fixation of the surface mount diode. However, for the existing equipment to complete the above process, it is necessary to pick up the surface mount diodes one by one in the magazine by a gripper and then insert them into the tape, and such a feeding speed is extremely slow, seriously restricting the production efficiency.

[0037] The present invention specifically discloses a high-speed feeding device for diode processing, as Figures 2 - 16 shown, including: a bottom mounting plate 11 and a support frame 12. There are multiple support frames 12. In this embodiment, three support frames 12 are taken as an example. The three support frames 12 are evenly spaced and installed on the bottom mounting plate 11. Each support frame 12 has the following layout: a feeding channel 13 is installed on one side of the top of the support frame 12. The chip diode 301 to be processed is conveyed from the feeding channel 13. It should be noted that the feeding channel 13 can be set for a relatively long distance and is connected to the device for conveying the chip diode 301 at the end, so as to continuously receive the chip diode 301. An outlet channel 14 is installed on the other side of the top of the support frame 12. The processed chip diode 301 is discharged through this outlet channel 14. The tape 300 required for the processing of the chip diode 301 is placed on the first auxiliary material supply area 15. The first auxiliary material supply area 15 is arranged on the upper part of the support frame 12. The rolled tape 300 is installed on the first auxiliary material supply area 15, while the tape 303 is placed on the second auxiliary material supply area 16. The second auxiliary material supply area 16 is arranged on the lower part of the support frame 12. A guiding frame 17 is installed on the feeding channel 13. A guiding wheel 151 for guiding the tape 300 to the guiding frame 17 is provided on the first auxiliary material supply area 15. The tape 300 is pulled out from the first auxiliary material supply area 15, passes through the guiding wheel 151, and then enters the guiding frame 17. The tape 300 is guided by the guiding frame 17 and slides on the surface of the feeding channel 13. Under the action of the guiding wheel 151, when the tape 300 pulled out from the first auxiliary material supply area 15 directly enters the guiding frame 17, it will not be bent, and can have a good curved movement route and will not get stuck at the turning point; A material ejecting member 18 is installed inside the support frame 12. The material ejecting member 18 is located below the feed channel 13. A gap is left between the feed channel 13 and the discharge channel 14. A pressing wheel group 19 is installed in the gap. A thumbwheel 110 is installed on the shaft at the lower part of the pressing wheel group 19. The thumbwheel 110 is provided with a plurality of shifting teeth along the circumferential direction. A sliding middle piece 111 is installed on the support frame 12. The movable part of the sliding middle piece 111 is connected to the material ejecting member 18. The shifting teeth of the thumbwheel 110 are in contact with the sliding middle piece 111. A power output mechanism 112 is arranged on the bottom mounting plate 11, and drives the pressing wheel groups 19 on the plurality of support frames 12 to rotate.

[0038] Specifically, the material belt 300 is first pulled out from the first auxiliary material supply area 15 and passed through the guide wheel 151, and then passed through the guide frame 17, so that the material belt 300 slides on the supply channel 13, and the material belt 300 is continuously pulled through the gap of the pressing wheel group 19. At the same time, the adhesive tape 303 is pulled from the second auxiliary material supply area 16 through the pressing wheel group 19, and the adhesive side of the adhesive tape 303 is in contact with the bottom of the material belt 300 and passes through the pressing wheel group 19 together. Under the rolling pressure of the pressing wheel group 19, the two will be pressed together, and as the pressing wheel group 19 rotates, the material belt 300 and the adhesive tape 303 are pulled to move, and the dial wheel 110 will also rotate accordingly, and the teeth will be moved while the dial wheel 110 rotates. The sliding middle piece 111 is intermittently toggled, and the sliding middle piece 111 lifts up the ejecting piece 18, thereby pushing the SMD diode 301 in the feeding channel 13 into the placement opening on the material belt 300. After the toggling teeth lose contact with the sliding middle piece 111, the ejecting piece 18 falls down, and the next SMD diode 301 moves forward. As the toggling teeth lift up the sliding middle piece 111 again, the ejecting piece 18 will push the SMD diode 301 in the feeding channel 13 into the placement opening on the material belt 300 again. Therefore, as the rotation speed of the pressing wheel assembly 19 increases, the speed at which the ejecting piece 18 pushes the SMD diode 301 into the material belt 300 will also increase.

[0039] In the process of the pressing wheel group 19 rolling the adhesive tape 303 and the material tape 300 together, the present invention pushes the top material piece 18 through the sliding middle piece 111 every time the material tape 300 is pulled a certain distance, thereby inserting the SMD diode 301 in the feeding channel 13 onto the material tape 300, and the adhesive tape 303 adheres to the material tape 300 under the rolling pressure of the pressing wheel group 19, thereby fixing the SMD diode 301. As the rotation speed of the pressing wheel group 19 increases, the placement speed of the SMD diode 301 will also increase, thereby effectively improving the processing efficiency.

[0040] Reference Figures 2 - 4As shown, the power output mechanism 112 includes: three groups of commutators 21 are arranged on the bottom mounting plate 11 according to the number of support frames 12, each group has three commutators 21, one of the commutators 21 is connected to the pressure wheel group 19 on the support frame 12, and the three groups of commutators 21 are connected together through a transmission shaft 22 and are connected laterally, so as to realize connecting the three groups of commutators 21 in series. At this time, a driving motor 23 is installed on the bottom mounting plate 11. After the driving motor 23 drives one group of commutators 21 through the transmission shaft 22, the three groups of commutators 21 can work together, so that all the pressure wheel groups 19 can rotate together at the same time.

[0041] Reference Figure 5 , Figure 7 , Figure 9 and Figure 10 As shown, the ejector 18 includes: an installation chamber 31 is opened on the support frame 12, a movable ejector block 32 is slidably installed in the installation chamber 31, the top of the movable ejector block 32 slides into the feeding channel 13, a guide rod 33 is fixedly installed in the installation chamber 31, the bottom of the movable ejector block 32 is slidably connected to the guide rod 33, and a spring 34 is sleeved on the guide rod 33. The function of the spring 34 is to keep the top of the movable ejector block 32 at the bottom of the feeding channel 13.

[0042] Specifically, the movable top block 32 is connected to the sliding middle piece 111, and the pressing wheel group 19 will rotate with the thumbwheel 110 during its rotation. The driving teeth on the thumbwheel 110 will drive the sliding middle piece 111, thereby causing the movable top block 32 to lift up the SMD diode 301 in the feeding channel 13, and the lifted SMD diode 301 will just be stuck on the material belt 300. After the driving teeth and the sliding middle piece 111 are out of contact, the movable top block 32 returns to its original position, and the next SMD diode 301 will move forward and come to the top of the movable top block 32 again. During the continuous rotation of the pressing wheel group 19, the material belt 300 and the adhesive tape 303 will be continuously pulled to move, and the thumbwheel 110 will intermittently lift up the movable top block 32, thereby sticking the SMD diode 301 in the feeding channel 13 to the material belt 300.

[0043] It should be noted that the material strip 300 will be pulled and moved during the rotation of the pressing wheel group 19. Therefore, in order to ensure that the movable top block 32 and the thumbwheel 110 can effectively cooperate to insert the patch diode 301 into the material strip 300, the gap between the multiple toggle teeth provided on the thumbwheel 110 needs to be adjusted to maintain a consistent distance with the gap between the holes provided on the material strip 300 under actual use conditions. The specific adjustment is as follows: when the pressing wheel group 19 clamps the material strip 300 and rotates and pulls it forward for a fixed distance, the thumbwheel 110 rotates accordingly, and the toggle teeth provided on the thumbwheel 110 will also swing accordingly for a distance. During the swinging process, the end of the toggle teeth contacts the movable top block 32 and lifts the movable top block 32. After the single toggle tooth contacts the movable top block 32 to reach the limit contact angle, the movable top block 32 is at the limit height. At this time, the patch diode 301 is moved by the movable top block 32. The material strip 300 is in a lifted state, and the holes on the material strip 300 are aligned just above the movable top block 32 under the rotation and pulling of the pressing wheel group 19; that is to say, while the pressing wheel group 19 pulls the material strip 300 to move, the toggle teeth arranged at intervals on the dial wheel 110 also push the movable top block 32 upward at the same time. When the material strip 300 is pulled to move so that the holes on the material strip 300 are aligned just with the movable top block 32, the movable top block 32 is also pushed to the highest point by the toggle teeth at this time, and the chip diode 301 can be just inserted into the material strip 300. At the same time, the contact between the toggle teeth and the movable top block 32 reaches the limit contact angle. After the dial wheel 110 continues to rotate, the toggle teeth and the movable top block 32 are disengaged, and the movable top block 32 returns to its original position until the next toggle tooth lifts the movable top block 32, thereby realizing effective cooperation between the dial wheel 110 and the movable top block 32.

[0044] Reference Figure 4 and Figure 10 As shown, it also includes: a bracket 91 fixedly installed on the feeding channel 13, a rubber wheel 92 rotatably set on the bracket 91, and rolling contact with the SMD diode 301 on the feeding channel 13, so that when the rubber wheel 92 rotates, the SMD diode 301 in the feeding channel 13 can actively slide to the area of ​​the top material piece 18, and a driving motor 93 is installed on the bracket 91 to drive the rubber wheel 92 to rotate.

[0045] Reference Figure 5 , Figure 6 and Figure 8As shown in the figure, the pressing and covering wheel set 19 includes: roller pressing wheels 41 that are connected in pairs at intervals to form a total of two groups. The interval distance between the two roller pressing wheels 41 in each group is at least greater than the width of the surface-mounted diode 301, so that the roller pressing wheels 41 will not press the surface-mounted diode 301 during rotation. The two groups of roller pressing wheels 41 are symmetrically arranged up and down and are rotatably installed on the support frame 12 between the feeding channel 13 and the discharging channel 14. The gap between the roller pressing wheels 41 arranged up and down is flush with the feeding channel 13. The roller pressing wheels 41 are provided with protruding convex teeth 42 at circumferential intervals, and the convex teeth 42 of the two groups of roller pressing wheels 41 arranged up and down are staggered from each other. During use, the tape 300 and the adhesive tape 303 are inserted into the gap between the two groups of roller pressing wheels 41. Then, the two side edges of the tape 300 and the adhesive tape 303 at this time will be clamped by the two groups of roller pressing wheels 41 arranged up and down, and the two will be adhered together under the rolling of the convex teeth 42. The pins 302 of the surface-mounted diodes 301 stuck on the tape 300 will be wrapped between the tape 300 and the adhesive tape 303. As the roller pressing wheels 41 rotate, the tape 300, the adhesive tape 303, and the surface-mounted diodes 301 that have been fixed pass through the gap of the roller pressing wheels 41 and finally enter the discharging channel 14 and are discharged. Among them, in order to ensure that the two groups of roller pressing wheels 41 can rotate stably in opposite directions, gears 43 are coaxially installed on the roller pressing wheels 41 and mesh with each other to keep the two groups of roller pressing wheels 41 rotating in opposite directions, so as to ensure that the two groups of roller pressing wheels 41 can rotate stably in opposite directions.

[0046] Referring to Figure 7 and Figure 15 As shown in the figure, it further includes: a protective ring 81 fixedly installed on the support frame 12. The protective ring 81 wraps the lower roller pressing wheels 41 in a semi-wrapped state. Among them, the height of the top of the protective ring 81 is lower than the height of the channel opening of the feeding channel 13. The purpose of doing this is to avoid interference of the protective ring 81 with the passing tape 300. The protective ring 81 is provided with a guiding channel 82 that bends towards the gap between the two groups of roller pressing wheels 41. After the adhesive tape 303 is pulled out from the second auxiliary material supply area 16, it can pass through the guiding channel 82 to better let the adhesive tape 303 pass into the gap between the two groups of roller pressing wheels 41, and at the same time, it can also avoid the tape 303 from breaking due to friction between the roller pressing wheels 41 and the adhesive tape 303.

[0047] Referring to Figure 6 、 Figures 10 - 12As shown in the figure, the feeding channel 13 includes: a first bottom plate 51 fixedly installed on one side of the top of the support frame 12. On the first bottom plate 51, restraint plates 52 are symmetrically installed. The tape 300 slides centered on the surfaces of the two restraint plates 52 under the action of the guiding frame 17. There is a gap between the two restraint plates 52 that allows the surface-mount diode 301 to pass through. And the opposite end faces of the two restraint plates 52 are provided with recessed passing grooves 53. After the surface-mount diode 301 is in the gap between the two restraint plates 52, the leads 302 of the surface-mount diode 301 will be placed into the passing grooves 53. In this way, when the surface-mount diode 301 slides on the two restraint plates 52, the passing grooves 53 restrict the leads 302 so that the surface-mount diode 301 will not break away from the restraint plates 52. A top material port 54 is opened on the first bottom plate 51 to allow the movable top block 32 to slide out. And the movable top block 32 is in the gap between the two restraint plates 52. After the surface-mount diode 301 slides above the movable top block 32, the movable top block 32 moves upward. Since the passing grooves 53 restrict the leads 302, it cannot move upward. At this time, the passing grooves 53 in the area of the restraint plate 52 close to the movable top block 32 need to be eliminated to form a release area 56 that allows the surface-mount diode 301 to move upward under the clamping action of the two restraint plates 52. In this way, the movable top block 32 can lift the surface-mount diode 301 upward and thus clamp it on the tape 300 that slides on the surface of the restraint plate 52. Among them, a blocking protrusion 55 in a raised shape is provided at the end of the first bottom plate 51. The function of the blocking protrusion 55 is to limit the movement of the surface-mount diode 301 to stop moving after reaching the area of the top material port 54. In this way, it can ensure that the movable top block 32 can lift the surface-mount diode 301 every time, and also prevent the surface-mount diode 301 from sliding beyond the working area of the movable top block 32.

[0048] Refer to Figure 6 and Figure 13 As shown in the figure, the discharging channel 14 includes: a second bottom plate 61 installed on the other side of the top of the support frame 12. A certain gap is left between the first bottom plate 51 and the second bottom plate 61 for installing the pressing wheel group 19. Limiting plates 62 are symmetrically installed on the second bottom plate 61. Anti-detachment cover plates 63 are jointly installed on the two limiting plates 62 on both sides. An access channel 64 that allows the surface-mount diode 301, the tape 303, and the tape 300 to pass through is formed between the anti-detachment cover plates 63 and the limiting plates 62. Specifically, after the tape 303, the tape 300, and the surface-mount diode 301 are connected together by being rolled by the pressing wheel group 19, they are then stuffed into the access channel 64 and discharged to a specified position under the guidance of the access channel 64 to avoid accumulation.

[0049] Refer to Figure 6 and Figure 14As shown, the guide frame 17 includes: a first bent plate 71 fixedly mounted on the constraint plate 52, the first bent plate 71 is in an L-shaped shape, and the corner is an arc-shaped bend, the second bent plate 72 is attached to the first bent plate 71 and then installed on the constraint plate 52, the first bent plate 71 is provided with a belt groove 73 for allowing the material belt 300 to be placed, the belt groove 73 is opened along the curved surface of the first bent plate 71, the material belt 300 is pulled out and inserted into the belt groove 73, and moves along the belt groove 73, and finally passes through the bottom of the first bent plate 71 along the surface of the constraint plate 52, so as to constrain the material belt 300 between the two constraint plates 52 The surface of the material strip 300 is centered and slides in the middle so that the material strip 300 and the SMD diode 301 can be accurately aligned. In order to prevent the upwardly pushed SMD diode 301 from being interfered by the first bent plate 71, a notch 74 is opened on the first bent plate 71 to allow the SMD diode 301 to pass through, and the width of the notch 74 must not exceed the width of the material strip 300. It is best to press down both sides of the material strip 300. In this way, when the SMD diode 301 is pushed upward, the material strip 300 in this area will not move upward with it, so that the SMD diode 301 can be stuck on the material strip 300.
