Then, the tape pulling clamping device 61 releases the tape and moves to between the cutting device 8 and the second roller 32 under the action of the tape pulling moving device 62. The tape pulling device realizes the output of a fixed length of the tape. Among them, the tape pulling moving device 62 includes a tape pulling moving cylinder or a tape pulling electric cylinder. The tape pulling moving cylinder is a multi-axis cylinder, and the tape pulling moving cylinder is fixed on the frame 1. The tape pulling clamping device 61 includes a tape pulling finger cylinder 611, a tape pulling upper jaw 612 and a tape pulling lower jaw 614. The tape pulling finger cylinder 611 is installed on the piston rod of the tape pulling moving cylinder; the tape pulling upper jaw 612 and the tape pulling lower jaw 614 are respectively installed on the first sliding table and the second sliding table of the tape pulling finger cylinder 611 and are arranged opposite to each other. A first pressing protrusion 613 is provided on the tape pulling upper jaw 612, and a first pressing groove 615 is provided on the tape pulling lower jaw 614. The first pressing protrusion 613 matches the first pressing groove 615.

The tape sticking lifting device is installed on the other side of the mounting frame 1 and is connected to the tape suction seat 73. Three vacuum suction holes 731 for adsorbing the tape are provided at the bottom of the tape suction seat 73. The tape sticking lifting device is used to drive the tape suction seat 73 to adsorb the tape and press the tape onto the lead. The tape sticking lifting device has two working positions. One is to bring the tape suction seat 73 close to the tape clamped on the material pulling fixing device 63, facilitating the adsorption of the tape by means of vacuum adsorption. The side of the tape with the back glue faces the lead below, and the tape suction seat 73 is attached to one side of the tape without back glue. The other working position of the tape sticking lifting device is to press the tape onto the lead and make the tape adhere to the film below the lead at the same time. The top of the tape suction seat 73 is elastic and can deform, so that the tape can adhere to the lead and the film below the lead. An elastic seat 732 made of elastic material can be installed on the top of the tape suction seat 73. A number of vacuum suction holes 731 are provided on the elastic seat 732.

The end of the piston rod of the tape pressing cylinder 72 is equipped with a tape suction seat 73. The tape suction cylinder 71 is used to attach the tape suction seat 73 to the tape. The tape suction seat 73 adsorbs the tape by vacuum. The tape pressing cylinder 72 is used to press the tape onto the lead through the tape suction seat 73. The switching between the two working positions is realized by the tape suction cylinder 71 and the tape pressing cylinder 72, with low cost, simple control and reliable operation. The tape sticking lifting device can also directly adopt an electric cylinder or a linear module.

[0037] During operation, install the tape roll onto the chuck 2, then pull the end of the tape so that the tape passes through the first roller 31, the photoelectric sensor 4, and the second roller 32 in sequence. The non-adhesive side of the tape is pressed against the first roller 31 and the second roller 32. Then, drive the upper tape clamping jaw 612 and the lower tape clamping jaw 614 to clamp the end of the tape by the tape pulling finger cylinder 611. A part of the end of the tape needs to be exposed. Next, retract the piston rod of the tape pulling moving cylinder, and the tape pulling moving cylinder drives the tape pulling finger cylinder 611 and the end of the tape to move to the fixed clamping jaw 632 of the tape pulling fixing device 63. Then, drive the fixed clamping jaw 632 to clamp the end of the tape by the fixed finger cylinder 631. The tape pulling moving cylinder drives the tape pulling clamping device 61 to reset to one side of the cutting device 8 and clamp the tape again. Then, drive the glue sucking seat 73 to descend above the tape by the glue sucking cylinder 71. The glue sucking seat 73 generates negative pressure through the vacuum generator to adsorb the tape to the bottom of the glue sucking seat 73. Next, drive the upper cutting knife 84 to descend by the cutting cylinder 82, and the upper cutting knife 84 cuts the tape through the lower cutting knife 85. Then, drive the glue sucking seat 73 and the tape to descend onto the lower lead by the glue pressing cylinder 72. The lead is first flattened by the fixture, and the tape is attached to the lead of the pressing piece and simultaneously attached to the film below the lead to fix the lead. Then, both the glue pressing cylinder 72 and the glue sucking cylinder 71 retract.

[0038] Embodiment 2

[0039] As Figure 9 and Figure 10As shown, on the basis of the above embodiment, in order to prevent the tape from falling off or retracting, a non-return device 5 is also included. The non-return device 5 is installed on the frame 1 and is located between the cutting device 8 and the material guiding device; the non-return device 5 includes an upper non-return seat 51, a lower non-return seat 55, a middle non-return seat 53, a non-return lifting shaft 52, a non-return roller 54 and a non-return spring. The upper non-return seat 51 and the lower non-return seat 55 are both fixed on the frame 1 and are arranged relatively. Four non-return lifting shafts 52 are provided, which are slidably inserted into the upper non-return seat 51 through linear bearings and are located at the four corners of the upper non-return seat 51. The bottom of the non-return lifting shaft 52 is connected to the middle non-return seat 53. Four non-return springs are provided, which are movably inserted into the non-return lifting shaft 52, and the two ends of the non-return springs are respectively against the upper non-return seat 51 and the middle non-return seat 53. There are two non-return rollers 54, which are rotatably mounted on the bottom of the middle non-return seat 53 and arranged opposite to the top of the lower non-return seat 55, and are used to press the tape onto the lower non-return seat 55 through a non-return spring. Guide blocks 531 are also provided on both sides of the middle non-return seat 53, and a guide groove 551 is also provided on the top of the lower non-return seat 55. The guide blocks 531 are movably inserted into the guide groove 551 to further guide the middle non-return seat 53, prevent the middle non-return seat 53 from rotating, and prevent the tape from deviating, so as to limit the tape from moving inside the middle non-return seat 53. Since the non-return rollers 54 press the tape onto the lower non-return seat 55, the tape is not easy to swing or move forward and backward, which improves the reliability and stability of the tape conveying, and especially can avoid the problem of the tape falling off caused by the rebound of the tape when the tape is cut.
