Description

Technical Field

[0001] This utility model belongs to the field of chip packaging technology, and in particular relates to a carrier tape hot melt coating device. Background Technology

[0002] In the field of chip manufacturing, the produced granular chips are usually packaged using long strip plastic carrier tapes. The carrier tapes have multiple evenly arranged chip slots. First, the chips are placed one by one into the chip slots, and then a hot melt coating device is used to heat-melt the sealing film to the carrier tape, thereby achieving the sealing of the carrier tape.

[0003] Existing hot melt laminating equipment has a relatively simple structure. After the hot press plate is heated by electricity, it is manually moved downwards to fuse the sealing film with the carrier tape. Then, the hot press plate is manually moved upwards to perform subsequent hot melt lamination of the carrier tape. This carrier tape hot melt lamination process has low production efficiency and cannot be adapted to large-scale production. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a highly efficient carrier tape hot melt coating device.

[0005] This utility model is implemented as follows: a carrier belt hot melt coating device includes a mounting plate, a motor is fixedly mounted on the back of the mounting plate, the motor shaft passes through the mounting plate and is fixedly connected to one end of an eccentric wheel, the axis of the motor shaft is not coaxial with the central axis of the eccentric wheel, the other end of the eccentric wheel is fixedly connected to a bearing, and the bearing is fixedly mounted on one end of a push plate.

[0006] The other end of the push plate is fixedly connected to an active block. Two spaced sliding rods are fixedly mounted on the active block. A retaining ring is fixedly mounted on the end of each sliding rod away from the active block. The diameter of the retaining ring is larger than the diameter of the sliding rod. A passive block is slidably mounted on each of the two sliding rods. A spring is sleeved on each of the two sliding rods between the retaining ring and the passive block.

[0007] The passive block is fixedly connected to a slide rail, the slide rail is slidably disposed in a slide groove, the slide groove is fixedly connected to a lower heating plate, the inner side of the lower heating plate is fixedly connected to the mounting plate, and at least one roller is rotatably provided on the upper end of the outer side of the lower heating plate;

[0008] The end of the slide rail away from the passive block is fixedly connected to an upper heating plate.

[0010] Specifically, the motor shaft is fixedly connected to the mounting hole on the eccentric wheel, and the axis of the mounting hole is offset from the central axis of the eccentric wheel.

[0011] This invention utilizes a motor to drive an eccentric wheel to rotate, which in turn drives a push plate to move downwards. The push plate, through an active block, a passive block, a slide bar, a retaining ring, a slide rail, and an upper heating plate, drives the upper heating plate downwards. When the upper roller on the upper heating plate moves downwards to the carrier belt, the upper roller and the lower roller press the carrier belt together and perform heat-melt coating, thereby melting the sealing film and the carrier belt together.

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0018] like Figures 1-4As shown in the figure, the present invention provides a carrier belt hot melt coating device, including a mounting plate 1. A motor 2 is fixedly mounted on the back of the mounting plate 1. The rotating shaft 21 of the motor 2 passes through the mounting plate 1 and is fixedly connected to one end of an eccentric wheel 3. The axis of the rotating shaft 21 of the motor 2 is not coaxial with the central axis of the eccentric wheel 3. That is, the rotating shaft 21 of the motor 2 is fixedly connected to the mounting hole 31 on the eccentric wheel 3. The axis of the mounting hole 31 is offset from the central axis of the eccentric wheel 3. The other end of the eccentric wheel 3 is fixedly connected to a bearing 4. The bearing 4 is fixedly mounted on one end of a push plate 5.

[0019] The other end of the push plate 5 is fixedly connected to an active block 6 by a bolt 61. Two spaced sliding rods 62 are fixed on the active block 6. A retaining ring 63 is fixed on the end of the two sliding rods 62 away from the active block 6, and the diameter of the retaining ring 63 is larger than the diameter of the sliding rod 62. A passive block 7 is slidably mounted on the two sliding rods 62. A spring 64 located between the retaining ring 63 and the passive block 7 is sleeved on the two sliding rods 62 respectively.

[0020] The passive block 7 is fixedly connected to a slide rail 8. The slide rail 8 is slidably installed in a slide groove 91. The slide groove 91 is fixedly connected to a lower heating plate 9. The inner side of the lower heating plate 9 is fixedly connected to the mounting plate 1. Two spaced lower rollers 92 are rotatably provided on the upper end of the outer side of the lower heating plate 9.

[0021] The end of the slide rail 8 away from the passive block 7 is fixedly connected to an upper heating plate 10. The lower end of the outer side of the upper heating plate 10 is provided with two spaced upper rollers 101, and the two upper rollers 101 and the two lower rollers 92 are arranged opposite each other.

[0022] The principle behind the carrier tape hot melt coating device of this invention for driving the upper heating plate 10 to move up and down is as follows:

[0023] First, start motor 2. The shaft of motor 2 will drive eccentric wheel 3 to rotate together. While rotating, eccentric wheel 3 will drive push plate 5 to move up and down.

[0024] When the push plate 5 moves upward, it pushes the active block 6 upward together. When the active block 6 moves upward to the passive block 7, it pushes the passive block 7 upward together. The passive block 7 drives the upper heating plate 10 to move upward together through the slide rail 8.

[0025] When the push plate 5 moves downward, it pulls the active block 6 downward, and the active block 6 pulls the two slide rods 62 downward. When the slide rods 62 move upward to the passive block 7, the retaining ring 63 compresses the spring 64 and pushes the passive block 7 downward. The passive block 7 drives the heating plate 10 downward through the slide rail 8 until the two upper rollers 101 and the two lower rollers 92 press the carrier belt tightly, at which point the motor 2 stops working. The downward elastic force generated by the compression of the spring 64 is applied to the passive block 7, and the elastic force is then applied to the upper heating plate 10 through the passive block 7 and the slide rail 8. This ensures that the two upper rollers 101 and the two lower rollers 92 apply a constant pressing force to the carrier belt while it is moving forward and undergoing hot melt coating, thus guaranteeing the quality of the hot melt coating of the carrier belt.

[0026] The specific process of hot-melt coating of carrier tape using the carrier tape hot-melt coating device of this utility model is as follows:

[0027] First, the upper heating plate 10 and the lower heating plate 9 are energized and heated. After being heated, the upper heating plate 10 and the lower heating plate 9 will transfer heat to the two upper rollers 101 and the two lower rollers 92, and the two upper rollers 101 and the two lower rollers 92 will also be heated.

[0028] Then, the carrier belt drive device (not shown) drives the carrier belt covered with the sealing film to move to the gap between the upper roller 101 and the lower roller 92;

[0029] Next, the control device controls the motor 2 to drive the push plate 5 downward through the eccentric wheel 3. The push plate 5 drives the upper heating plate 10 downward through the active block 6, the passive block 7 and the slide rail 8, so that the two upper rollers 101 and the two lower rollers 92 press the carrier belt and perform hot melt coating, so that the sealing film is covered on the carrier belt. At the same time, the traction device continues to pull the carrier belt covered with the sealing film forward, and the two upper rollers 101 and the two lower rollers 92 continue to perform hot melt coating on the subsequent carrier belts.

[0030] After the hot melt coating of all the carrier tapes is completed, the control device cuts off the power to the upper heating plate 10 and the lower heating plate 9 to stop heating, and controls the motor 2 to drive the push plate 5 to move upward through the eccentric wheel 3. The push plate 5 drives the upper heating plate 10 to move upward through the active block 6, the passive block 7 and the slide rail 8, so that the two upper rollers 101 are disengaged from the carrier tape. The winding device (not shown) pulls all the carrier tapes away and winds them together.

[0031] This invention utilizes a motor 2 to drive an eccentric wheel 3 to rotate, which in turn drives a push plate 5 to move downwards. The push plate 5, through an active block 6, a passive block 7, a slide rod 62, a retaining ring 63, a slide rail 8, and an upper heating plate 10, drives the upper heating plate 10 to move downwards. When the upper roller 101 on the upper heating plate 10 moves downwards to the carrier belt, the upper roller 101 and the lower roller 92 press the carrier belt together and perform hot-melt coating, thereby hot-melting the sealing film and the carrier belt together. At the same time, the carrier belt continues to move forward, achieving continuous hot-melt coating of the carrier belt. The entire process requires no manual operation, significantly improving the production efficiency of hot-melt coating of the carrier belt and adapting to large-scale production.

[0032] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
