DETAILED DESCRIPTION

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0029] Reference Figures 1 to 7 As shown, the present invention is an electronic component dispensing device, comprising a support leg 1, a support plate 2 is fixedly mounted on the top of the support leg 1, a first groove 21 is formed on the top of the support plate 2, and a conveyor belt 3 is rotatably mounted on the inner surface of the first groove 21;

[0030] It also includes a glue dispensing mechanism for dispensing glue on electronic components;

[0031] The glue dispensing mechanism includes a second bracket 5, on the top of which an air pump 51 is fixedly installed, one side of the air pump 51 is fixedly connected to an air outlet pipe 52, the other end of the air outlet pipe 52 is fixedly connected to a valve 521, the bottom of the valve 521 is fixedly connected to a storage box 53, one side of the storage box 53 is fixedly connected to a rubber hose 54, one end of the rubber hose 54 is fixedly connected to a rubber cylinder 57, the bottom of the rubber cylinder 57 is fixedly connected to a glue gun 58, the top of the rubber cylinder 57 is fixedly connected to a connecting plate 56, the top of the connecting plate 56 is fixedly connected to a second electric telescopic rod 55, and the second electric telescopic rod 55 is slidably installed at the bottom of the second bracket 5.

[0032] During the use of the existing glue dispensing machine, the glue in the glue cylinder 57 will gradually decrease due to the small size of the glue cylinder 57 and the small amount of glue stored. Manually adding glue to the glue cylinder 57 not only increases the burden on workers but also affects work efficiency. When there is a lack of glue in the glue cylinder 57, it may be impossible to replenish the glue in time, resulting in insufficient glue dispensed on the electronic components, and then rework.

[0033] During use, the electronic components are continuously conveyed to the bottom of the glue gun 58 via the conveyor belt 3. When the electronic components reach the bottom of the glue gun 58, the glue gun 58 applies the glue in the glue barrel 57 onto the electronic components. During use, the glue in the glue barrel 57 gradually decreases, and the air pump 51 increases the pressure in the storage box 53 by supplying air to the storage box 53 through the air outlet pipe 52 and the valve 521. There is glue in the storage box 53. When there is pressure in the storage box 53, the glue in the storage box 53 flows to the glue barrel 57 through the glue hose 54, replenishing the glue in the glue barrel 57. During use, the height of the glue gun 58 is controlled by the second electric telescopic rod 55, which is conducive to changing the glue injection position according to the thickness of the electronic components.

[0034] Further, such as Figure 2 As shown, a first bracket 4 is fixedly installed on the top of the support plate 2, a collecting box 41 is fixedly installed on the top of the first bracket 4, a first suction pipe 42 is fixedly connected to one side of the collecting box 41, the first suction pipe 42 passes through the inner cavity of the collecting box 41, a second suction pipe 43 is fixedly connected to the top of the collecting box 41, one end of the second suction pipe 43 passes through the first bracket 4 and is fixedly connected to a dust collection plate 44, a first electric telescopic rod 45 is fixedly connected to the top of the dust collection plate 44, the first electric telescopic rod 45 is fixedly installed on the bottom of the first bracket 4, and cooperates with the valve 521 to transport air into the storage box 53 when needed to increase the pressure in the storage box 53.

[0035] Before dispensing glue on electronic components, the surface of the electronic components needs to be cleaned, otherwise dust may be sealed between the electronic components and the glue during dispensing, making the electronic components unusable.

[0036] When the electronic components move on the conveyor belt 3, they will first pass through the bottom of the dust collection plate 44. The height of the dust collection plate 44 is adjusted by the first electric telescopic rod 45 according to the height of different electronic components. When the electronic components pass under the dust collection plate 44, under the action of the air pump 51, the bottom of the dust collection plate 44 will generate suction, and the dust on the electronic components will be sucked into the collection box 41.

[0037] Further, such as Figure 3 and Figure 4 As shown, an annular plate 411 is fixedly installed on the bottom of the inner surface of the collection box 41 , a filter box 412 is movably installed on the top of the annular plate 411 , and the connection between the first suction pipe 42 and the collection box 41 is located at the bottom of the filter box 412 .

[0038] Since the other end of the air pump 51 is connected to the storage box 53, the dusty air cannot be blown into the storage box 53. At this time, the dusty air needs to be filtered. When the air passes through the collection box 41, the dust in the air will be filtered by the filter box 412, and the dust remains in the filter box 412. The clean air flows to the air pump 51 through the first intake pipe 42, and the filter box 412 is pushed to a certain height by the annular plate 411. In conjunction with the first intake pipe 42, the dusty air can completely pass through the filter box 412, thereby achieving the purpose of filtering the dust in the air and then inputting it into the air pump 51.

[0039] Further, such as Figure 5 As shown, a third groove 501 is formed at the bottom of the second bracket 5, a threaded rod 553 is rotatably mounted on the inner surface of the third groove 501, a slider 551 is slidably mounted on the inner surface of the third groove 501, a threaded hole 552 is formed on one side of the slider 551, and the threaded rod 553 is threadedly mounted on the inner surface of the threaded hole 552;

[0040] One end of the threaded rod 553 passes through the second bracket 5 and is fixedly connected to the first motor 554 . The first motor 554 is fixedly mounted on one side of the second bracket 5 , and the second electric telescopic rod 55 is fixedly mounted on the bottom of the slider 551 .

[0041] When dispensing glue on electronic components, it is necessary not only to adjust the height of the glue gun 58, but also to enable the glue gun 58 to move horizontally. By rotating the threaded rod 553 with the first motor 554, the slider 551 can slide in the third groove 501. When the slider 551 slides, it can drive the second electric telescopic rod 55 to slide along the third groove 501, thereby achieving the purpose of adjusting the position of the glue gun 58 in the horizontal direction.

[0042] Further, such as Figure 6 and Figure 7 As shown, the top of the support plate 2 is provided with two second grooves 22, and a special-shaped plate 61 is slidably installed on the inner surface of the second groove 22. A pad 62 is fixedly installed on one side of the special-shaped plate 61. Two fixed plates 63 are fixedly installed on the bottom of the support plate 2. A reciprocating screw rod 64 is commonly threadedly connected to one side of the two fixed plates 63. One end of the reciprocating screw rod 64 is fixedly connected to a second motor 65. The second motor 65 is fixedly installed on the bottom of the support plate 2;

[0043] A third bracket 7 is fixedly mounted on the top of the support plate 2. A fourth groove 71 is formed on the inner surface of the third bracket 7. A limit plate 73 is slidably mounted on the inner surface of the fourth groove 71.

[0044] A cylinder 72 is fixedly installed on the top of the third bracket 7. The piston rod of the cylinder 72 passes through the top of the third bracket 7 and is fixedly connected to the top of the limiting plate 73. The two special-shaped plates 61 are slidably installed on one side of the limiting plate 73.

[0045] Before dispensing glue on electronic components, in order to prevent the electronic components from shaking during the dispensing process, which may cause the glue to be unable to be dispensed at the designated position and make the electronic components unusable, the electronic components need to be fixed.

[0046] During operation, first, under the action of the cylinder 72, the piston rod of the cylinder 72 extends, causing the limit plate 73 to slide on the inner surface of the fourth groove 71. When the limit plate 73 slides to the bottom of the fourth groove 71 and the bottom of the limit plate 73 contacts the conveyor belt 3, the limit plate 73 can prevent the electronic components on the conveyor belt 3 from continuing to pass. At this time, under the action of the second motor 65, the reciprocating screw rod 64 rotates, and the two special-shaped plates 61 slide toward each other along the second groove 22, which can clamp the two sides of the electronic component. The backing plate 62 is installed on the other side to provide a buffer between the special-shaped plate 61 and the electronic components, effectively preventing the special-shaped plate 61 from damaging the electronic components and further fixing the electronic components. After the electronic components are fixed, the electronic components can be glued by the glue gun 58. After the glue is glued, the limit plate 73 is pulled back by the piston rod of the cylinder 72. The two special-shaped plates 61 move to both sides under the action of the second motor 65 to release the restraint on the electronic components. The electronic components continue to move to the next process under the action of the conveyor belt 3.

[0047] Working principle: First, the electronic components are placed on the conveyor belt 3. As the conveyor belt 3 moves, the electronic components first pass through the bottom of the dust collection plate 44. Under the action of the air pump 51, the dust collection plate 44 sucks out the dust on the electronic components. The sucked-out air containing dust is filtered by the filter box 412, then flows through the air pump 51, and is finally blown into the storage box 53 by the air outlet pipe 52, thereby increasing the air pressure in the storage box 53. The glue liquid in the storage box 53 flows to the glue cylinder 57 through the glue hose 54 under air pressure, and the glue gun 58 sprays the glue liquid in the glue cylinder 57 toward the electronic components, thereby completing the dispensing of the electronic components.

[0048] Before dispensing glue, the electronic components need to be fixed. First, under the action of the piston rod of the cylinder 72, the limit plate 73 slides down to the top of the conveyor belt 3 to prevent the electronic components on the conveyor belt 3 from continuing to move. Then, the two special-shaped plates 61 approach each other under the action of the second motor 65 and the reciprocating screw 64 to clamp the electronic components. At this time, the glue gun 58 can dispense glue on the electronic components.

[0049] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
