Technical Field

[0001] The present invention belongs to the technical field of chip packaging, and in particular relates to a carrier tape hot-melt laminating device. Background Art

[0002] In the field of chip manufacturing, the granular chips produced are usually packaged through a long plastic carrier tape. The carrier tape is provided with multiple evenly arranged chip slots. First, the chips are placed one by one in the chip slots, and then a hot melt laminating device is used to heat-melt the sealing film and the carrier tape together to achieve sealing of the carrier tape.

[0003] Existing hot-melt laminating devices have a relatively simple structure. After the hot platen is powered on and heated, it is manually moved downward to fuse the sealing film to the carrier tape. The hot platen is then manually moved upward to perform hot-melt lamination on the subsequent carrier tape. This carrier tape hot-melt lamination process has low production efficiency and is not suitable for large-scale production. Summary of the Invention

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

[0011] The present invention utilizes a motor to drive the eccentric wheel to rotate, and the eccentric wheel drives the push plate to move downward. The push plate drives the upper heating plate to move downward through the active block, the passive block, the slide rod, the retaining ring, the slide rail and the upper heating plate.

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

[0018] like Figures 1-4 As shown, an embodiment of the present invention provides a carrier hot-melt laminating device, comprising a mounting plate 1, a motor 2 fixedly mounted on the back of the mounting plate 1, a rotating shaft 21 of the motor 2 passing through the mounting plate 1 and fixedly connected to one end of an eccentric wheel 3, the axis of the rotating shaft 21 of the motor 2 being 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 a mounting hole 31 on the eccentric wheel 3, the axis of the mounting hole 31 deviates from the central axis of the eccentric wheel 3, the other end of the eccentric wheel 3 is fixedly connected to a bearing 4, and 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 sliding rods 62 are fixed on the active block 6. A retaining ring 63 is fixed to the end of the two sliding rods 62 away from the active block 6. 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 is respectively sleeved on the two sliding rods 62 and located between the retaining ring 63 and the passive block 7.

[0020] The passive block 7 is fixedly connected to a slide rail 8, the slide rail 8 is slidably arranged 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, and the upper end of the outer side of the lower heating plate 9 is rotatably provided with two lower rollers 92 arranged at intervals;

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

[0022] The principle of the carrier hot melt laminating device of the present invention driving the upper heating plate 10 to move up and down is:

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

[0024] When the push plate 5 moves upward, the push plate 5 pushes the active block 6 to move upward together. When the active block 6 moves upward to the passive block 7, it pushes the passive block 7 to move 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, the push plate 5 pulls the active block 6 to move downward together, and the active block 6 pulls the two slide bars 62 to move downward together. When the slide bar 62 moves upward to the passive block 7, the retaining ring 63 compresses the spring 64 and pushes the passive block 7 to move downward together. The passive block 7 drives the heating plate 10 to move downward together through the slide rail 8 until the two upper rollers 101 and the two lower rollers 92 press the carrier tape tightly. 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 acts on the upper heating plate 10 through the passive block 7 and the slide rail 8, so that the two upper rollers 101 and the two lower rollers 92 always apply a constant pressing force to the carrier tape while the carrier tape moves forward and is hot-melt coated, thereby ensuring the quality of the hot-melt coating of the carrier tape.

[0026] The specific process of hot-melt coating the carrier tape by the carrier tape hot-melt coating device of the present invention is as follows:

[0027] First, the upper heating plate 10 and the lower heating plate 9 are powered on and heated. After being heated, the upper heating plate 10 and the lower heating plate 9 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 are also heated.

[0028] Then, the carrier tape driving device (not shown) drives the carrier tape 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 tape and perform hot-melt coating, thereby covering the carrier tape with the sealing film. At the same time, the traction device continues to pull the carrier tape 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 tapes.

[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 separated from the carrier tape, and the winding device (not shown) pulls away all the carrier tapes and rolls them together.

[0031] The present invention utilizes the motor 2 to drive the eccentric wheel 3 to rotate, and the eccentric wheel 3 drives the push plate 5 to move downward. The push plate 5 drives the upper heating plate 10 to move downward through the active block 6, the passive block 7, the slide rod 62, the retaining ring 63, the slide rail 8 and the upper heating plate 10. When the upper roller 101 on the upper heating plate 10 moves downward to the carrier tape, the upper roller 101 and the lower roller 92 press the carrier tape and perform hot-melt coating, thereby hot-melting the sealing film and the carrier tape together. At the same time, the carrier tape continuously moves forward to realize continuous hot-melt coating of the carrier tape. The entire process does not require manual operation, which significantly improves the production efficiency of the carrier tape hot-melt coating and is suitable for large-scale production.

[0032] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
