Description

[0002] After the production of diodes, they will be packaged. Some square chip resistors and wire-wound resistors with small volumes are directly packaged in bags. When wire-wound resistors are packaged in bags, they are directly put into the bags without being sorted in an orderly manner. For example, the packaging capacity of each bag is 200 resistors of a certain specification, and these 200 resistors are directly put into the packaging bag without being sorted. During transportation, the resistors in the packaging bag are squeezed and rubbed, and the slender leads on the resistors will be intertwined with each other.

[0014] The present invention brings the following effects: 1. The present invention intermittently feeds materials through the intermittent feeding mechanism. The film tape to be pressed is clamped between two hot pressing wheel modules, and the resistors fall between the two film tapes from the intermittent feeding mechanism. As the hot pressing wheel modules rotate, the resistors will be wrapped with the film while maintaining a fixed spacing. Finally, through the wrapping of the film tape, the resistors are connected into a line at intervals in an orderly manner, so as to avoid the disorderly scattering of the resistors and be able to package the resistors into the bag in an orderly manner. Even if the packaging bag is squeezed, the pins of the resistors in the packaging bag will not be entangled with each other; the resistors fixed and packaged at intervals by the film tape are more intuitive in terms of the obtained quantity and are more convenient to count when in use.

[0015] 2. The provided intermittent feeding mechanism enables the resistors to fall onto the hot pressing wheel modules one by one at a predetermined interval. At the same time, in cooperation with the hot pressing wheel modules, the resistors can be arranged and coated on the film tape at a fixed interval and firmly hot-pressed together with the two film tapes during the rotation of the hot pressing wheel modules.

[0016] 3. The first damping block and the second damping block provided in the present invention can keep the film tape placed on the rotating shaft in a tensioned state during the pulling process; the provided check block can prevent the already fallen resistors from sliding upward. After the resistors fall between the two film tapes, during the rotation of the hot pressing wheel modules, the included angle formed by the film tapes drives the resistors to slide upward, resulting in the resistors being unable to enter the receiving grooves, while the check block can prevent the resistors from sliding upward.

It can be understood that the specific embodiments described herein are only used to explain the present application, rather than limiting the present application.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the protection scope of the present application.

[0030] In the description of the present application, it should be noted that, unless otherwise clearly defined and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection, an electrical connection or a communication with each other; it may be directly connected, or indirectly connected through an intermediate medium, and it may be the internal communication of two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0031] The present invention specifically discloses a diode film packaging device, as Figures 1 - 11 shown, including: a support frame 11 with four legs at the bottom, which raises the support frame 11 through the legs provided at the bottom. A film supply bracket 12 is movably installed on the left and right sides of the support frame 11. After the film supply bracket 12 is turned over and opened, the space inside the support frame 11 can be exposed. An intermittent feeding mechanism 13 is fixedly installed in the middle of the support frame 11. The intermittent feeding mechanism 13 is vertically installed on the support frame 11 and is located between the two film supply brackets 12. A feeding hopper 14 is installed on the top of the intermittent feeding mechanism 13. The resistor 200 to be packaged is placed into the feeding hopper 14. Through the feeding hopper 14, the resistor 200 can accurately enter the intermittent feeding mechanism 13. A set of hot pressing wheel modules 15 are symmetrically installed in the support frame 11 and are located below the intermittent feeding mechanism 13. A fitting notch 151 for allowing the resistor 200 to be embedded is provided on the surface of the hot pressing wheel module 15. This fitting notch 151 is in a semicircular shape and is approximately equivalent to the diameter of the resistor 200. The two hot pressing wheel modules 15 rotate towards each other through the meshing of a gear set 16. The fitting notches 151 on the two hot pressing wheel modules 15 rotate and match together under the action of the gear set 16 to form a complete circular hole capable of accommodating the resistor 200.

[0032] During use, a roll of film tape 201 is installed on the two side film supply brackets 12. Then, the film tapes 201 on both sides are pulled out and leaned against each other, and they are passed through between the two hot pressing wheel modules 15 together. At this time, in accordance with Figure 7As shown, the resistor 200 drops from the intermittent feeding mechanism 13 onto the two film tapes 201. As the hot pressing wheel module 15 rotates towards each other, the resistor 200 will be clamped in the fitting notch 151, and the protruding ends between the fitting notches 151 will abut against each other and thermally press and adhere the two film tapes 201 together to wrap the resistor 200, thus realizing the film packaging of the resistor 200. The packaged resistors 200 are evenly spaced and connected into a single line through the film tape 201 without scattering.

[0033] A first motor 17 for driving the operation of the intermittent feeding mechanism 13 is installed on the intermittent feeding mechanism 13. A second motor 18 is installed on the support frame 11 for driving the gear set 16 to rotate. The power supply connector 19 is detachably connected to the hot pressing wheel module 15 to provide the power required for the hot pressing wheel module 15.

[0034] Refer to Figures 3 - 5 As shown, the intermittent feeding mechanism 13 includes: two symmetrically arranged feeding frames 21. The feeding frames 21 are provided with semi-circular arches. The two feeding frames 21 are arranged opposite to each other. Limit plates 22 are installed on both sides of the two feeding frames 21. The limit plates 22 are provided with gap notches that disconnect the limit plates 22 along the area close to the arches of the feeding frames 21. The gap notches are only provided along the arched area on one side. A connecting plate 23 is connected to the limit plates 22 to fixedly hold the gap notches of the two separated limit plates 22. The gap notches form a passage 24 for the material to pass through. The lower part of the connecting plate 23 is fixedly installed on the support frame 11. A feeding wheel 25 is rotatably arranged on the limit plates 22. The feeding wheel 25 is located in the arched area of the feeding frame 21. The first motor 17 drives the feeding wheel 25 to rotate. The feeding wheel 25 is provided with grooves along the circumference to allow a single resistor 200 to enter.

[0035] Specifically, during use, the resistor 200 enters the passage 24 from the feeding hopper 14 and falls into the groove of the feeding wheel 25. As the feeding wheel 25 rotates, the resistor 200 slides along the passage 24. When the resistor 200 reaches the vertical passage 24 below as it rotates with the feeding wheel 25, the resistor 200 will fall along this passage 24 onto the hot pressing wheel module 15. When the feeding wheel 25 stops rotating, the subsequent resistors 200 will not continue to fall, thus realizing intermittent feeding to avoid blockage and jamming of the resistors 200 in the area of the hot pressing wheel module 15.

[0036] Refer to Figure 5 and Figure 6As shown, it also includes: the unloading wheel 25 has an annular groove 31 that is concave toward the center of the circle along the circumferential direction, the ring plate 32 is fixed on the feeding frame 21, and is partially embedded in the annular groove 31, the ring plate 32 will not rotate together with the unloading wheel 25, the part of the ring plate 32 in the channel 24 will not exceed the depth of the groove of the unloading wheel 25, and the convex point 33 is protruding on the ring plate 32. And the convex point 33 protrudes within the range of the groove, and the position of the convex point 33 is on the ring plate 32 at the position of the falling area of ​​the resistor 200 in the channel 24. Specifically, when the unloading wheel 25 moves with the resistor 200 in the channel 24, after reaching the channel 24 leading to the area of ​​the hot pressing wheel module 15, the resistor 200 will contact the convex point 33, and the resistor 200 will be ejected from the groove of the unloading wheel 25 through the convex point 33, so as to avoid the situation that the resistor 200 may be stuck in the groove.

[0037] Reference Figure 1 , Figure 2 and Figure 8 As shown, the film supply support 12 includes: a fixed plate 41 movably mounted on both sides of the support frame 11 through a hinge, a support plate 42 fixed on the fixed plate 41, and a vertically bent limit portion 43 is provided on one side of the support plate 42 close to the connecting plate 23, the limit portion 43 is used to press the film strip 201 close to the connecting plate 23, and a rotating shaft 44 is rotatably arranged on the support plate 42. Specifically, when in use, the rolled film strip 201 is placed on the rotating shaft 44, and after the fixed plate 41 is turned over and opened, one end of the film strip 201 is pulled out to bypass the limit portion 43. The function of the limit portion 43 can prevent the surface of the film strip 201 from being scratched during the sliding process, and ensure that the bending angle of the film strip 201 is not too large. After the film strip 201 is pulled out, it passes between the two hot pressing wheel modules 15.

[0038] Reference Figure 8 As shown, it also includes: a first damping plate 45 fixed on the support plate 42, a rotating shaft 44 passing through the first damping plate 45, a second damping plate 46 slidably set at the end of the rotating shaft 44 and fitted with the first damping plate 45, an adjusting bolt 47 is screwed on the end of the rotating shaft 44 to adjust the pressing force between the first damping plate 45 and the second damping plate 46, and elastic protrusions 48 are evenly arranged at circumferential intervals on the rotating shaft 44.

[0039] Specifically, in order to allow the membrane tape 201 to remain straight when pulled out, the adjusting bolt 47 is tightened to increase the pressing force between the first damping plate 45 and the second damping plate 46. The rotation of the rotating shaft 44 will not be loose enough to be able to rotate easily, and a certain pulling force is required to rotate it. In addition, the elastic ridges 48 provided on the rotating shaft 44 can keep the membrane tape 201 inserted on the rotating shaft 44 stable and will not slip.

[0040] Reference Figure 3 , Figure 9 andFigure 10 As shown, a notch is formed in the lower part of the connecting plate 23. A check block 51 is rotatably arranged in this notch. There is a movable gap 54 between the connecting plate 23 and the check block 51. The check block 51 can swing up and down in this movable gap 54. The position of the check block 51 is at the gap of the channel 24. Therefore, a passing notch 55 allowing the pins of the resistor 200 to pass through is formed in the check block 51. In this way, when the resistor 200 drops, the pins will not be blocked by the check block 51 and cannot fall. A balance block 52 is connected to the side of the check block 51 close to the movable gap 54. The function of the balance block 52 is to keep the check block 51 in a flat balance state. A protruding bump 53 is arranged in the notch at the lower part of the connecting plate 23. On the side of the bump 53 away from the movable gap 54, the function of the bump 53 is to limit the check block 51 from tilting upwards. The check block 51 is arranged on both connecting plates 23 on both sides, and the check blocks 51 on both sides are both at the gaps of the channel 24. The opposite end faces of the two check blocks 51 are inclined surfaces, the inclined angle is inclined from top to bottom, and the lower end face protrudes slightly.

[0041] Specifically, after the resistor 200 falls through the channel 24, it will land between two film tapes 201. According to Figure 7 As shown, when the previous resistor 200 is about to complete the film coating, the next resistor 200 drops. As the hot pressing wheel module 15 rotates, the included angle formed by the two film tapes 201 will shrink according to Figure 9 As shown. Therefore, the resistor 200 that lands on the two film tapes 201 will slide upwards due to the shrinking of the included angle formed by the film tapes 201. When the resistor 200 slides upwards, it cannot be inserted into the fitting notch 151 of the hot pressing wheel module 15. Therefore, when the resistor 200 drops, it will cross over the check block 51 along the inclined surface of the check block 51. After the check block 51 swings downwards to allow the resistor 200 to pass through, it returns to the flat state. Finally, the resistor 200 lands between the two film tapes 201. As the hot pressing wheel module 15 rotates and the included angle formed by the film tapes 201 shrinks, the situation where the resistor 200 slides upwards will be blocked by the check block 51, so that the resistor 200 cannot slide upwards. Then, during the rotation of the hot pressing wheel module 15, the resistor 200 can be clamped in the fitting notch 151.

[0042] Referring to Figure 3 and Figure 11As shown in the figure, the hot pressing wheel module 15 includes: two circular pressing wheels 61 symmetrically arranged. The two pressing wheels 61 are rotationally arranged inside the support frame 11 through shafts, and the surfaces of the two pressing wheels 61 are in contact with each other. The pressing wheel 61 is provided with a recessed receiving groove 62 along the circumferential direction. The receiving groove 62 is semi-circular, and the radius of the receiving groove 62 is equivalent to the radius of the resistor 200. After the two pressing wheels 61 rotate simultaneously, a complete round hole can be formed after the two receiving grooves 62 rotate to the same position. Therefore, after the film tapes 201 on both sides are pulled out and pass through the two pressing wheels 61 together, when the resistor 200 falls on the two film tapes 201, as the two pressing wheels 61 rotate towards each other, after the resistor 200 enters the receiving groove 62, the film tapes 201 on both sides will be pressed on the surface of the resistor 200 simultaneously.

[0043] Among them, a heating component is installed inside the pressing wheel 61. The outward protruding contact parts between the receiving grooves 62 will contact each other during the rotation of the pressing wheel 61. Therefore, the film tape 201 between the two pressing wheels 61 will also be pressed, and the heating component will heat the protruding contact parts. During the process of the two pressing wheels 61 pressing the film tape 201, the two separated film tapes 201 can be hot-pressed together, and then the resistor 200 can be wrapped. And uneven patterns 63 are provided on the surface of the contact part of the protruding area between the receiving grooves 62. In this way, during the hot pressing process of the film tape 201, the two film tapes 201 will adhere to each other more firmly. Among them, the heating component can be provided on both of the two pressing wheels 61, or can be provided on one of the pressing wheels 61.

[0044] Refer to Figure 11 As shown in the figure, the heating component includes: a heating frame 64. The heating frame 64 is provided with the same number of independent heating parts according to the number of protruding areas between the receiving grooves 62. Setting the independent heating parts can realize the local heating of the pressing wheel 61 without heating up the entire pressing wheel 61. The heating frame 64 is embedded in the pressing wheel 61. Since the heating frame 64 needs to rotate with the pressing wheel 61, a power connection slip ring 65 is fixedly installed on the heating frame 64 and connected to the heating frame 64. The power supply slip ring 66 is in sliding contact with the power connection slip ring 65. One end of the power connection slot 67 is fixed on the power supply slip ring 66, and the other end is fixed on the support frame 11 for the power supply connector 19 to connect, so as to realize power supply through the sliding contact between the power supply slip ring 66 and the power connection slip ring 65.

[0045] The above-described embodiments only represent the preferred embodiments of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations, improvements and substitutions can be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention should be subject to the appended claims.
