[0020] The present utility model will be further described in detail below with reference to the accompanying drawings and through specific embodiments. The following embodiments are only descriptive and not restrictive of the protection scope of the present utility model.

[0021] Please refer to Figures 1-4, the present utility model provides a technical solution: an apparatus for applying a high-temperature tape to a lead frame, including a tape winding reel 1 for connecting the tape. A high-temperature tape roll 2 is wound around the outer surface of the tape winding reel 1 for bonding articles. A connecting plate 3 is movably arranged on the front surface of the tape winding reel 1 through a rotating shaft for arranging a connecting rod 4. A connecting rod 4 is fixedly arranged on the top of the connecting plate 3 for arranging a fixing frame 5. A fixing frame 5 is fixedly arranged at the top position near the rear surface of the connecting rod 4 for arranging corresponding components. A cavity is formed inside the fixing frame 5. A movable rod 6 is movably arranged on the front surface of the connecting rod 4 through a rotating shaft for arranging a blade 7. A blade 7 is arranged on the outer surface of the fixing frame 5 for cutting the tape. A movable roller 8 is movably arranged at a position near one side of the inner bottom of the fixing frame 5 for arranging a rough rubber sleeve 11.

[0022] Furthermore, the high-temperature tape roll 2 is made of polyimide material. With this design, the high-temperature tape roll 2 is more durable.

[0023] Furthermore, notch openings 9 are formed on both sides of the fixing frame 5, and the notch openings 9 and the fixing frame 5 are integrally designed. The notch openings 9 facilitate the tape to pass through the fixing frame 5.

[0024] Furthermore, one end of the movable rod 6 is fixedly connected to the blade 7, and the bottom of the blade 7 contacts the fixing frame 5. The blade 7 functions to cut the tape.

[0025] Furthermore, a stop block 10 is fixedly arranged on one side of the fixing frame 5, and the top of the stop block 10 contacts the blade 7. The stop block 10 can limit the blade 7.

[0026] Furthermore, a rough rubber sleeve 11 is fixedly arranged on the outer surface of the movable roller 8. The rough rubber sleeve 11 can increase the friction with the back surface of the tape, making the tape not easy to loosen.

[0027] Furthermore, a waterproof film is fixedly arranged on the outer surface of the high-temperature tape roll 2, and the waterproof film functions to prevent water.

[0028] Working principle: When using this device, the user passes the tape head counterclockwise through the fixing frame 5 from the notch opening 9 and out from the other notch opening 9. Then, when the user needs to cut the tape, the user pushes the blade 7 to rotate. Since the connecting rod 4 on the blade 7 is movably arranged at the central position of the fixing frame 5, the blade 7 can rotate, and thus the blade 7 will contact the tape to cut the tape. After cutting, the tape head will remain in the current position.

[0029] It can be known from the above working process that:

[0030] This is applied to the heating and bonding of a lead frame with a high-temperature tape. By setting up a fixing bracket 5, a notch 9, a movable rod 6, and a blade 7, when the device is in use, it can ensure that after the tape is cut, the tape head remains in the current position, eliminating the need for the user to search for it, saving time for the user, bringing convenience to the user, improving the practicality of the device, and meeting the user's usage requirements.

[0031] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
