Description

[0002] With the rapid development of electronic information technology, electrical components, as an important part of various electronic products, have a continuously growing market demand. In order to ensure the quality and performance of electrical components, effective protection measures are needed during transportation and storage. Heat shrink film packaging, as an economical and efficient protection method, is widely used in the packaging of electrical components. It not only provides good visual effects, but more importantly, it can play a role in moisture-proof, dust-proof and physical protection.

[0003] However, in actual operation, when electrical components are wrapped with heat shrink film and then heat-shrunk, the air in the heat shrink film cannot be completely discharged, resulting in expansion during the heating and shrinking process. This expansion may generate sufficient internal pressure to cause the seal of the heat shrink film to rupture or cause the adhesive strength of the seal to decrease, affecting the sealing effect; and the air that has not been discharged will form bubbles in the film during the heat shrinking process, which not only affects the aesthetics of the product, but the presence of bubbles also indicates the incompleteness of the packaging and potential quality problems, which may affect consumers' trust in product quality. Summary of the invention

[0004] In view of this, the present invention provides an automated material packaging equipment for an electrical component supply chain, which can solve the problem that when electrical components are wrapped with heat shrink film and then heat shrunk, the air remaining in the heat shrink film is prone to expand during the heating and shrinking process of the heat shrink film, causing the seal of the heat shrink film to be unable to withstand and rupture, thereby affecting the sealing effect, aesthetics and product quality.

[0029] See also Figure 1-Figure 3 As shown, the lifting mechanism includes a mounting frame 601 and a second electric push rod 602; the mounting frame 601 is arranged on the right side of the top of the second conveyor 3; the second electric push rod 602 is arranged on the upper side of the mounting frame 601, and the telescopic rod of the second electric push rod 602 is connected to the top of the closed frame 7.

[0030] See also Figure 2 As shown, the sealing mechanism includes a first sealing strip 901 and a second sealing strip 902 ; the first sealing strip 901 is disposed at the bottom of the closing frame 7 ; and the second sealing strip 902 is disposed at the bottom of the sliding plate 8 .

[0031] See also Figure 5As shown, the hot melt mechanism includes a sliding frame 1501, a second spring 1502 and a hot melt device 1503; the sliding frame 1501 is slidably arranged on the cutter 13; the second spring 1502 is connected between the front and rear sides of the top of the sliding frame 1501 and the cutter 13; the hot melt devices 1503 are symmetrically arranged on the bottom of the sliding frame 1501, and the two hot melt devices 1503 are respectively located on both sides of the cutter 13, and the bottom surface of the hot melt device 1503 is lower than the bottom end of the cutter 13, and the hot melt device 1503 on the left side contacts with the right side of the sliding plate 8.

[0032] When in use, firstly, the heat shrink film is loaded on the heat shrink film packaging machine 4, and the heat shrink film packaging machine 4 heat-melts the heat shrink film into a cylindrical shape, and then the left end of the cylindrical heat shrink film is heat-melted and sealed manually using a hot melt gun to form a U-shaped heat shrink film (the open end of the U-shaped heat shrink film faces right), and then the electrical component 101 is placed on the conveyor belt of the first conveyor 2 (such as Figure 3As shown), the first conveyor 2 is controlled to convey the electrical component 101 to the left until the electrical component 101 moves to the left into the U-shaped heat shrink film of the heat shrink film packaging machine 4, and then the heat shrink film packaging machine 4 is controlled to unwind the heat shrink film, and the first conveyor 2 is controlled to continue to convey the electrical component 101 to the left, so that the electrical component 101 moves to the left synchronously with the U-shaped heat shrink film, until the electrical component 101 in the U-shaped heat shrink film moves to the left and passes the top of the connecting block 14, and comes to the bottom of the closing frame 7, and then the second electric push rod 602 is controlled to drive the closing frame 7 and the sliding plate 8 to move downward, until the first sealing strip 901 and the second sealing strip 902 at the bottom of the closing frame 7 and the sliding plate 8 are in contact with the conveyor belt of the second conveyor 3. During this period, when the sliding When the second sealing strip 902 at the bottom of the plate 8 contacts the heat shrink film, the second sealing strip 902 will squeeze the heat shrink film downward and tightly adhere to the conveyor belt of the second conveyor 3, thereby pressing the open end of the U-shaped heat shrink film, and then starting the booster pump 11 for a period of time, so that the booster pump 11 draws outside air into the closed frame 7, thereby pressurizing the space in the closed frame 7, and then squeezing the air in the heat shrink film. When the pressure on the air in the heat shrink film is greater than the gravity of the second sealing strip 902 and the sliding plate 8 and the elastic force of the first spring 10, the air in the heat shrink film will squeeze the second sealing strip 902 and the sliding plate 8 to move upward, and the first spring 10 is compressed, so that the second sealing strip 902 no longer presses the open end of the U-shaped heat shrink film, thereby making the U-shaped heat shrink film The air in the film can be discharged to the right, thereby squeezing out the air in the U-shaped heat shrink film, so that the U-shaped heat shrink film can be subsequently heat-shrunk. After a period of time, the booster pump 11 is controlled to be turned off. When the air in the U-shaped heat shrink film is no longer sufficient to squeeze the second sealing strip 902 and the sliding plate 8 to move upward, the first spring 10 returns to its original state, and the first spring 10 drives the sliding plate 8 and the second sealing strip 902 to move downward and reset. Then, the first electric push rod 12 is controlled to drive the cutter 13, the sliding frame 1501 and the heat fuser 1503 to move downward. When the heat fuser 1503 contacts the U-shaped heat shrink film, the heat fuser 1503 will drive the U-shaped heat shrink film to move downward until the heat fuser 1503 presses the U-shaped heat shrink film against the top of the connecting block 14. At this time, the top of the connecting block 14 The U-shaped heat shrink film will also be used to limit the heat fuser 1503, so that the heat fuser 1503 and the sliding frame 1501 can no longer move downward. When the cutter 13 continues to move downward, the second spring 1502 is compressed. When the cutter 13 contacts the open end of the U-shaped heat shrink film, the cutter 13 will cut off the open end of the U-shaped heat shrink film and enter the cutting groove at the top of the connecting block 14. Then, the heat fuser 1503 is controlled to perform hot-melt sealing on the compressed heat shrink film. During this period, the heat fuser 1503 on the left side will perform hot-melt sealing on the open end of the U-shaped heat shrink film to complete the sealing of the electrical component 101 in the U-shaped heat shrink film, and the heat fuser 1503 on the right side will perform hot-melt sealing on the left end of the next tubular heat shrink film to form the next U-shaped heat shrink film.Then, the first electric push rod 12 is controlled to drive the cutter 13 to move upward and reset, so that the cutter 13 leaves the cutting groove at the top of the connecting block 14. During this period, the second spring 1502 gradually returns to its original state. After the second spring 1502 is reset, the second spring 1502 will drive the sliding frame 1501 and the hot melt 1503 to move upward and reset, so that the hot melt 1503 is separated from the heat shrink film. Then, the second electric push rod 602 is controlled to drive the closing frame 7 and the sliding plate 8 to move upward and reset, so that the first sealing strip 901 and the second sealing strip 902 at the bottom of the closing frame 7 and the sliding plate 8 are aligned with the conveyor belt of the second conveyor 3. Separate, so that the second sealing strip 902 loosens the heat shrink film that packages the electrical component 101, and then the second conveyor 3 conveys the packaged electrical component 101 to the left to the heat shrink machine 5, and then the heat shrink machine 5 shrinks the heat shrink film on the surface of the electrical component 101, so that the heat shrink film can be closely attached to the surface of the electrical component 101, and then the heat shrink machine 5 conveys the package of the heat-shrunk electrical component 101 to the left to discharge, so that the packaging process of the electrical component 101 can be completed, and then the above operation is repeated to repeatedly package the electrical component 101.

[0033] See also Figure 6 As shown, it also includes a pushing mechanism, which includes a third electric push rod 17 and a first push plate 18; the third electric push rod 17 is arranged on the upper front side of the first conveyor 2; the telescopic rod of the third electric push rod 17 is connected to the first push plate 18, and the first push plate 18 is used to push the electrical component 101 into the heat shrink film.

[0034] By setting up a pushing mechanism, when the first conveyor 2 conveys the electrical component 101 to the left into the U-shaped heat shrink film of the heat shrink film packaging machine 4, the third electric push rod 17 can drive the first push plate 18 to move to the left rear side, so that the first push plate 18 pushes the electrical component 101 into the middle position inside the U-shaped heat shrink film, so that the electrical component 101 can be in the middle position inside the U-shaped heat shrink film, so that the electrical component 101 can be packaged with the U-shaped heat shrink film later, and then the third electric push rod 17 can drive the first push plate 18 to move to the right front side to reset.

[0035] See also Figure 7-Figure 9As shown, it also includes an adjustment mechanism, which includes a servo motor 19, a screw rod 20, a movable plate 21 and a bellows 22; the servo motor 19 is symmetrically arranged on the upper front side of the heat shrink machine 5; the screw rods 20 are symmetrically arranged on the upper inner side of the heat shrink machine 5; the front ends of the two screw rods 20 are respectively connected to the output shafts of the two servo motors 19; two movable plates 21 are threadedly connected between the two screw rods 20, and the range between the two movable plates 21 is used for the heat shrink machine 5 to shrink the heat shrink film; the bellows 22 is connected between the movable plate 21 on the front side and the air inlet on the inner side of the heat shrink machine 5, and the bellows 22 is also connected between the movable plate 21 on the rear side and the air outlet on the inner side of the heat shrink machine 5.

[0036] Before use, the servo motor 19 can be controlled to drive the screw rod 20 to rotate forward or reverse according to the distance between the front and rear sides of the electrical component 101, so as to drive the two movable plates 21 to move closer or farther away, thereby adjusting the distance between the two movable plates 21, and then making the distance between the two movable plates 21 slightly larger than the distance between the front and rear sides of the electrical component 101, so as to match the heat shrinking space of the electrical component 101 in the heat shrinking machine 5; after that, when the packaged electrical component 101 enters the heat shrinking machine 5, the packaged electrical component 101 will be between the two movable plates 21, and then the packaged electrical component 101 will be shrinked by the heat shrinking machine 5. When the component 101 is heat-shrunk, the hot air in the heat shrink machine 5 will be discharged into the space between the two movable plates 21 through the bellows 22, so as to heat-shrink the packaged electrical component 101. By controlling the distance between the two movable plates 21 within a suitable range, the electrical component 101 can be heat-shrunk in an adapted space. The appropriate heat-shrinking space can ensure that the hot air is evenly distributed around the electrical component 101, so that the heat-shrinkable film can be evenly heated and shrunk. If the space is too large, it may cause uneven heat distribution, affecting the consistency and tightness of the shrinkage; if the space is too small, the electrical component 101 may not be able to enter the heat-shrinking space.

[0037] See also Figure 7-Figure 9 As shown, a guide plate 23 is also included; the right side of the bottom of the movable plate 21 is connected with the guide plate 23, and the guide plate 23 is used to introduce the packaged electrical components 101 between the two movable plates 21.

[0038] By providing the guide plate 23 , it is convenient for the guide plate 23 to accurately guide the packaged electrical component 101 between the two movable plates 21 .

[0039] See also Fig.10As shown, a screening mechanism is also included, which includes a camera 24, a controller 25, a fourth electric push rod 26, a second push plate 27 and a discharge plate 28; a camera 24 is installed on the left side of the closed frame 7, and the camera 24 is used to shoot the electrical component 101; a controller 25 is arranged on the left side of the top of the closed frame 7, and the camera 24 and the second conveyor 3 are electrically connected to the controller 25; two fourth electric push rods 26 are arranged on the upper left rear side of the second conveyor 3, and the fourth electric push rods 26 are electrically connected to the controller 25; a second push plate 27 is connected between the telescopic rods of the two fourth electric push rods 26, and the second push plate 27 is used to push out the electrical component 101 on the second conveyor 3; a discharge plate 28 is arranged on the upper left front side of the second conveyor 3, and the discharge plate 28 is used to discharge the electrical components 101 pushed out from the second conveyor 3, so as to screen the electrical components 101.

[0040] By setting up a screening mechanism, when the operator needs to screen the electrical component 101 products, the camera 24 can be used to shoot the electrical component 101 under the closed frame 7, and then the camera 24 transmits the shooting result to the data center through the controller 25, and the data center classifies the electrical component 101 according to the shooting result. If the classification result is that it needs to be kept, no subsequent operation is required; if the classification result is that it does not need to be kept, when the second conveyor 3 transports the electrical component 101 to the left to the front of the second push plate 27, the controller 25 will control the second conveyor 3 to stop conveying the electrical component 101, and then the controller 25 will control the fourth electric push rod 26 to drive the second push plate 27 to move forward, so that the second push plate 27 pushes the electrical component 101 on the second conveyor 3 forward, so that the electrical component 101 moves onto the discharge plate 28 to slide and discharge, and then the controller 25 will control the fourth electric push rod 26 to drive the second push plate 27 to move backward and reset, so that the electrical component 101 products can be automatically screened.
