Further, the inner width adjustment motor 33 and the outer width adjustment motor 34 arranged on the bottom plate 1 can more accurately drive the movement distance of the inner track plate 31 and the outer track plate 32, thereby more accurately controlling the distance between the inner track plate 31 and the outer track plate 32 in the track assembly 3, thereby meeting the use requirements.

[0046] In addition, in some embodiments, the width adjustment limiting photoelectric sensor 14 is also fixed on the bottom plate 1. The width adjustment limiting photoelectric sensor 14 can monitor the movement state of the inner track plate 31 and the outer track plate 32, thereby feeding back the movement range of the inner track plate 31 and the outer track plate 32 along the Y direction, and avoiding the movement of the inner track plate 31 and the outer track plate 32 beyond the limited distance range. Further, in some embodiments, the first and second distance measuring sensors 12 and 13 are also fixed on the outer track plate 32.

[0051] Specifically, the track assembly 3 is provided with a good chip into the tape position before the front detection assembly 5, at which the robot puts the good chip into the empty position of the tape, and the tape drives the chip to move along the X direction to the front detection position below the front camera group 52, and the slide cylinder 53 drives the front camera group 52 to move along the Y direction to the top of the chip to be detected for photographing detection. When the vision system determines that the chip is qualified, the tape continues to move along the X direction to the heat sealing structure at a set pace, and when the vision system determines that the chip is unqualified, the tape driving action is automatically paused, the tape stops moving, the slide cylinder 53 drives the front camera group 52 to move in the reverse Y direction to the avoidance position, away from the top of the chip, and the hot stamping head in the hot stamping structure is raised and reset. At the same time, the robot also takes out a good chip from the good chip tray to replace the unqualified chip in the tape. After the replacement is completed, the slide cylinder 53 drives the front camera group 52 to move to the top of the chip again to detect and confirm the new chip. After the chip meets the requirements, the tape driving action resumes, and the tape continues to move to the heat sealing structure. In front of the heat sealing structure, the tape overlaps with the cover tape and enters the heat sealing structure, and then the hot stamping heads in the outer heat sealing assembly 102 and the inner heat sealing assembly 101 are simultaneously pressed to heat plastic seal the cover tape and the tape. The sealed tape continues to move along the X direction to the bottom of the rear camera group 62, and the rear camera group 62 takes a photo of the tape and detects whether the seal of the tape is intact through the vision system. If the seal is intact, the tape continues to move to the material collecting assembly 9 for winding and storage. When the rear camera group 62 detects that the seal of the tape is abnormal, the system sends an alarm to remind manual intervention in time, such as adjusting the tape feeding speed, adjusting the cover tape offset, adjusting the hot stamping head temperature and pressure, etc.

[0052] In some embodiments, the first end and the second end of the outer track plate 32 are respectively provided with a tape pressing plate 35 and a tape pressing plate 36.

In a specific embodiment, the cutting edge of the cutting knife is located at the top, and when the cutting knife is needed to cut the ribbon, a driving structure such as a cylinder or a motor drives the cutting knife to move upward, so as to cut the ribbon.

[0055] In some embodiments, the cover tape feeding assembly 7 includes a cover tape feeding roll 71, a cover tape guide wheel set 72, and a cover tape fine adjustment structure 73. The cover tape feeding roll 71 is a cover tape stored in a roll. The cover tape guide wheel set 72 is used to guide the cover tape to the cover tape fine adjustment structure 73. The cover tape fine adjustment structure 73 is used to adjust the position of the cover tape relative to the carrier tape.

[0056] The carrier tape feeding assembly 8 includes a carrier tape feeding roll 81 and a carrier tape feeding wheel set 82. The carrier tape feeding roll 81 is an empty carrier tape to be used and stored in a roll. The carrier tape feeding wheel set 82 is used to adjust and guide the carrier tape into the track between the inner track plate 31 and the outer track plate 32.

[0057] The material collecting assembly 9 includes a finished product tray 91 and a material collecting wheel set 92. The finished product tray 91 is used to wind and store the heat-sealed ribbon. The material collecting wheel set 92 is used to tension the ribbon and guide the ribbon to the finished product tray 91.

[0058] Specifically, the carrier tape in the carrier tape feeding roll 81 is extracted, folded by the carrier tape feeding wheel set 82, and then threaded into the track assembly 3 through the groove at the bottom of the bottom plate 1. The inner track plate 31 and the outer track plate 32 automatically adjust the distance between the two tracks according to different widths of the carrier tape. The cover tape film at the cover tape feeding roll 71 is extracted, guided into the cover tape fine adjustment structure 73 through multiple foldings of the cover tape guide wheel set 72, and then threaded into the track assembly 3 through the inlet below the cover tape fine adjustment structure 73.

At this time, the carrier tape and the cover tape have been bonded into a ribbon and threaded out to the cutting assembly 37 through the ribbon pressing plate 36, entered the material collecting wheel set 92, and then buckled into the reel buckle of the finished product tray 91 for winding and storage. In addition, a motor is arranged at the axis of the finished product tray 91 to drive the finished product tray 91 to rotate, thereby assisting the winding and collection of the ribbon.

[0059] In some embodiments, the cap tape fine adjustment structure 73 is provided with a first adjusting member and a second adjusting member arranged opposite to each other along the Y direction.

[0060] Further, the cap tape fine adjustment structure 73 can be used in cooperation with the rear detection assembly 6. When the rear detection assembly 6 detects that the position between the cap tape and the carrier tape deviates, the cap film cannot completely cover the grid positions on the carrier tape, and thus the grid positions of the carrier tape are not fully packaged. The first adjusting motor 731 and the second adjusting motor 732 can drive the first push plate 733 and the second push plate 734 to move, respectively, so as to adjust the position of the cap film, so that the cap film can better adhere to the carrier tape, and the packaging process can be stably and reliably performed. The cap tape guide wheel 735 can guide and arrange the movement of the cap film, so that the movement of the cap tape is more smooth.

[0061] In some embodiments, the first end of the track assembly 3 is provided with an optical detection assembly 38, and the optical detection assembly 38 includes a receiver and a generator, which are arranged on the inner track plate 31 and the outer track plate 32, respectively.

[0062] Specifically, the optical detection assembly 38 is located at the position where the good chips enter the carrier tape. When the mechanical hand places the good chips into the empty grid positions of the carrier tape, the chips may, occasionally, be incorrectly placed, and the chips may be tilted and raised. The generator of the optical detection assembly 38 can excite detection light to the receiver. When the chips are tilted and raised, the optical detection assembly 38 can timely and accurately detect the state of the tilted and raised chips, so as to timely issue an alarm to remind the staff to intervene, so that the packaging efficiency of the chips is higher and more stable and reliable.

[0063] In some embodiments, the outer track plate 32 is fixed with a counting assembly 39, and the counting assembly 39 is located between the heat sealing structure and the material receiving assembly 9. The counting assembly 39 includes a mounting frame, and the mounting frame is fixed with an optical detector. Specifically, the counting assembly 39 can record the number of small holes on the outer side of the carrier tape, so as to convert the moving distance of the carrier tape or the number of chips. On the one hand, the number of chips that have been heat-sealed and packaged can be counted, and on the other hand, data support can be provided for the cutting work of the cutting assembly 37.

[0064] In some embodiments, the bottom surface of the bottom plate 1 is provided with an adjusting seat 11 extending along the Y direction, and the bottom plate 1 is in sliding connection with the adjusting seat 11. The adjusting seat 11 can adjust the position of the bottom plate 1 and the entire ribbon device thereon relative to the workbench, so that the ribbon device can be matched with the chip conveying line and the mechanical hand to complete the ribbon packaging of the chips.

[0065] In addition, in some embodiments, a floating pressing block is also arranged in the track assembly 3, which is also used to press the ribbon to reduce the shaking of the ribbon during heat sealing, reduce the jumping of the chips in the carrier tape holes caused by the impact of the heat pressing head or the movement of the carrier tape, and improve the stability of the carrier tape conveying, thereby improving the stability of the chips during the ribbon packaging.

[0066] In summary, in the chip ribbon packaging device, when the ribbon packaging of the chips is performed, the empty carrier tape reel is manually sleeved into the carrier tape loading shaft to form a carrier tape loading reel 81, and then the material belt is drawn out to be wound after passing through the carrier tape loading wheel set 82, and then passes through the material groove in the bottom plate 1 along the X direction from the second end to the first end of the track assembly 3, is folded back from the first end of the track assembly 3, and then is inserted into the track groove of the track assembly 3, and then the carrier tape in the track groove is driven to move from the first end to the second end by the driving tape feeding needle wheel, the inner track plate 31 and the outer track plate 32 automatically adjust the distance between the two tracks according to different widths of the carrier tape, and the outer width adjusting motor 34 and the inner width adjusting motor 33 independently adjust the positions of the inner and outer two tracks, respectively. The cover tape loading reel 71 needs to be manually loaded into the cover tape rotating shaft, the cover tape film is drawn out, and then the cover tape is inserted into the track assembly 3 through the cover tape fine adjustment structure 73 after being wound multiple times by the cover tape loading wheel set, and the cover tape is coincided with the carrier tape in the track assembly 3, and then is drawn out after passing below the heat sealing structure. At this time, the carrier tape and the cover tape have been adhered together and passed through the ribbon pressing plate 36, and then are drawn out of the cutting assembly 37. After entering the material collecting wheel set 92, the carrier tape is buckled into the reel buckle of the finished material disc 91. After the ribbon feeding is completed, it is necessary to check whether the carrier tape holes are buckled into the tape feeding needle wheels at the output ends of the first driving motor 41 and the second driving motor 42 below the carrier tape pressing plate 35 and the ribbon pressing plate 36, and the carrier tape holes are pressed tightly by the carrier tape pressing plate 35 and the ribbon pressing plate 36. When the first driving motor 41 and the second driving motor 42 rotate synchronously, the carrier tape continuously moves in the track assembly 3. The motor in the material collecting assembly 9 rotates the finished material disc 91 to start winding the ribbon. After this debugging is completed, the heating temperature and the sealing pressure of the heat sealing structure and other heat sealing parameters need to be set. When the temperature reaches the set value, a section of empty material ribbon can be manually tested for heat sealing, and when the sealing effect meets the production requirements, the normal ribbon production process can be started.

[0067] The above are only preferred embodiments of the present application, and it should be pointed out that, for those skilled in the art, without departing from the technical principles of the present application, a number of improvements and substitutions can be made, and these improvements and substitutions should also be considered as the protection scope of the present application.
