Description

Technical Field

[0001] This invention relates to capacitor manufacturing equipment, and more particularly to a carrier tape receiving device and method for a capacitor base plate machine. Background Technology

[0002] A capacitor mounting machine is an automated device that assembles capacitors with base plates to form surface mount capacitors, prints specifications and model numbers on the surface of the surface mount capacitors, and finally packages the surface mount capacitors using carrier tape. Carrier tape is a strip-shaped product used in electronic packaging; it has a specific thickness and evenly distributed holes along its length for holding electronic components and positioning holes for indexing and positioning.

[0003] The existing capacitor mounting machine's carrier tape receiving device does not have any detection mechanism, which poses a risk that defective capacitors and good capacitors are packaged on the same carrier tape, especially capacitors with poor appearance, thus causing defective capacitors to enter the market. Summary of the Invention

[0004] To address the shortcomings of the prior art, this invention provides a carrier tape receiving device and method for a capacitor mounting machine, which can screen defective products during the packaging process of surface mount capacitors.

[0005] The technical problem to be solved by the present invention is achieved through the following technical solution: A carrier tape receiving device for a capacitor board mounting machine includes: The conveyor base is provided with a conveyor groove that can accommodate the carrier belt, and the conveyor groove is provided with a discharge port that allows a single hole in the carrier belt to fall out. The front feeding mechanism and the rear feeding mechanism are respectively located at the front and rear ends of the conveyor base, and are used to drive the carrier belt to be conveyed forward on the conveyor base; A visual inspection mechanism is mounted on the conveyor base and located on the side of the discharge port near the rear feeding mechanism, and is used to perform visual inspection on the chip capacitors in the carrier tape. The first cutting mechanism is disposed on the conveying base and located between the discharge port and the vision inspection mechanism. It is used to cut off and separate the cavity containing the defective capacitor from the carrier tape when the vision inspection mechanism detects that there is a surface-mount capacitor with poor appearance. The packaging heat sealing mechanism is mounted on the conveyor base and located on the side of the discharge port near the front feeding mechanism, and is used to heat-press the packaging tape onto the carrier belt.

[0006] Furthermore, the front-end feeding mechanism includes a front-end driver, a front-end rotating shaft, two front-end feed rollers, and a front-end rotary encoder. The conveying base extends two front-end connecting parts at one end near the front-end feeding mechanism, and the conveying groove is located between the two front-end connecting parts. The two ends of the front-end rotating shaft are respectively connected to the two front-end connecting parts, and the two front-end feed rollers are arranged opposite each other on the front-end rotating shaft with their gap aligned with the conveying groove. The front-end driver drives the front-end rotating shaft to rotate, and the front-end rotary encoder is disposed on the front-end rotating shaft.

[0007] Furthermore, the rear-end feeding mechanism includes a rear-end driver, a rear-end rotating shaft, two rear-end feed rollers, and a rear-end rotary encoder. The conveying base extends two rear-end connecting parts at one end near the rear-end feeding mechanism, and the conveying groove is located between the two rear-end connecting parts. The two ends of the rear-end rotating shaft are respectively connected to the two rear-end connecting parts, and the two rear-end feed rollers are arranged opposite each other on the rear-end rotating shaft with their gap aligned with the conveying groove. The rear-end driver drives the rear-end rotating shaft to rotate, and the rear-end rotary encoder is disposed on the rear-end rotating shaft.

[0008] Furthermore, the outer periphery of the rear feed roller is provided with spaced belt-pulling pins, which are embedded in the positioning holes of the carrier belt to drive the carrier belt forward; the outer periphery of the rear feed roller is not provided with any belt-pulling pins, so that the carrier belt is driven forward by friction.

[0009] Furthermore, after the first cutting mechanism cuts the carrier tape, the conveying length of the front section of the carrier tape is positioned according to the measured number of revolutions of the front rotary encoder, and the conveying length of the rear section of the carrier tape is positioned according to the measured number of revolutions of the rear rotary encoder; before the first cutting mechanism cuts the carrier tape, and after the packaging heat-sealing mechanism heat-presses and fixes the packaging tape onto the two cut sections of carrier tape, the conveying length of the entire carrier tape is positioned according to the measured number of revolutions of the rear rotary encoder.

[0010] Furthermore, the conveying base is provided with a baffle at a position corresponding to the vision inspection mechanism. The baffle covers and shields a partial area of ​​the conveying groove and is provided with an inspection hole to expose a single chip capacitor in the carrier tape. The baffle also extends to cover the discharge port and is provided with a clearance groove corresponding to the first cutting mechanism.

[0011] Furthermore, the carrier tape take-up device also includes: The second cutting mechanism is located on the side of the front feeding mechanism away from the packaging heat sealing mechanism, and is used to cut the carrier tape with the packaging tape heat-sealed. The receiving mechanism is located on the side of the second cutting mechanism away from the front feeding mechanism, and is used to wind up the carrier tape with the heat-sealed packaging tape.

[0012] Furthermore, the receiving mechanism includes a receiving tray, a receiving driver, a receiving sensor, and a receiving bracket. The receiving tray is rotatably mounted on the receiving bracket, and the receiving driver is connected to drive the receiving tray to rotate. The receiving sensor is mounted on the receiving bracket and is used to detect the thickness or length of the carrier tape in the receiving tray. When the thickness or length of the carrier tape in the receiving tray reaches a preset value, the second cutting mechanism cuts the carrier tape heat-sealed with the packaging tape.

[0013] A method for receiving carrier tape in a capacitor holder board machine includes the following steps: Step 1: Control the front-end feeding mechanism and the rear-end feeding mechanism to drive the carrier belt forward on the conveyor base so that the carrier belt passes through the vision inspection mechanism, the first cutting mechanism and the packaging heat sealing mechanism in sequence. The vision inspection mechanism performs visual inspection on the chip capacitors in the carrier belt, and the packaging heat sealing mechanism heat-presses and fixes the packaging tape on the carrier belt. Step 2: When the visual inspection mechanism detects a surface mount capacitor with poor appearance, proceed to steps 3-5. When the visual inspection mechanism does not detect a surface mount capacitor with poor appearance, repeat steps 1 and 2. Step 3: Control the front-end feeding mechanism and the rear-end feeding mechanism to transport the cavity portion of the carrier tape containing the defective capacitor to the first cutting mechanism; Step 4: Control the first cutting mechanism to cut and separate the cavity containing the defective capacitor from the carrier tape; Step 5: Control the front-end feeding mechanism and the rear-end feeding mechanism to drive the two cut sections of carrier tape to continue to convey forward, so as to push the cavity containing the defective capacitor to the discharge port for discharge, and convey the two cut sections of carrier tape to the packaging heat-sealing mechanism, where the packaging heat-sealing mechanism heat-presses and fixes the packaging tape onto the two cut sections of carrier tape.

[0014] Furthermore, in step 1, the carrier tape receiving method of the capacitor base plate machine, after the carrier tape passes through the vision inspection mechanism, the first cutting mechanism and the packaging heat sealing mechanism in sequence, also passes through the second cutting mechanism and the receiving mechanism in sequence. The second cutting mechanism cuts the carrier tape with the packaging tape heat-sealed, and the receiving mechanism winds up the carrier tape with the packaging tape heat-sealed.

[0015] The present invention has the following beneficial effects: The carrier tape receiving device of the present invention uses two sets of feeding mechanisms to feed the carrier tape at the front and rear ends of the conveying base respectively, and the discharge port is set in the conveying groove of the conveying base. The visual inspection mechanism and the first cutting mechanism are set between the discharge port and the rear feeding mechanism, and the packaging heat sealing mechanism is set between the discharge port and the front feeding mechanism. When the visual inspection mechanism detects the presence of a surface mount capacitor with a defective appearance, the first cutting mechanism can cut and separate the cavity containing the defective capacitor from the carrier tape. Then, the front feeding mechanism and the rear feeding mechanism respectively drive the two cut sections of carrier tape to continue to be conveyed forward, thereby pushing the separated cavity to the discharge port for discharge. Then, the packaging heat sealing mechanism heat-presses and fixes the packaging tape to the two cut sections of carrier tape, so that the two cut sections of carrier tape can be connected by the packaging tape, thereby achieving the purpose of defective product screening during the packaging process of surface mount capacitors.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

Therefore, they should not be construed as limitations on this invention.

[0028] Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first," "second," or "third" may explicitly or implicitly include one or more of that feature. In the description of this invention, "multiple" means two or more, unless otherwise explicitly specified.

[0029] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," "fixing," and "setting," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0030] Example 1 like Figure 1-3 As shown, a carrier tape receiving device for a capacitor holder board machine includes: The conveying base 1 is provided with a conveying groove 11 that can accommodate the carrier belt A, and the conveying groove 11 is provided with a discharge port 12 that allows a single hole A1 in the carrier belt A to fall out. The front feeding mechanism 2 and the rear feeding mechanism 3 are respectively located at the front and rear ends of the conveying base 1, and are used to drive the carrier belt A to be conveyed forward on the conveying base 1. The visual inspection mechanism 4 is disposed on the conveying base 1 and located on the side of the discharge port 12 near the rear feeding mechanism 3, and is used to perform visual inspection on the chip capacitor B in the carrier tape A. The first cutting mechanism 5 is disposed on the conveying base 1 and located between the discharge port 12 and the visual inspection mechanism 4. It is used to cut and separate the cavity A1 containing the defective capacitor from the carrier tape A when the visual inspection mechanism 4 detects that there is a surface-mount capacitor B with a defective appearance. The packaging heat sealing mechanism 6 is mounted on the conveyor base 1 and located on the side of the discharge port 12 near the front feeding mechanism 2, and is used to heat-press the packaging tape C onto the carrier tape A.

[0031] The carrier tape receiving device of the present invention employs two sets of feeding mechanisms to transport the carrier tape A at the front and rear ends of the conveying base 1, respectively. A discharge port 12 is provided within the conveying groove 11 of the conveying base 1. A visual inspection mechanism 4 and a first cutting mechanism 5 are positioned between the discharge port 12 and the rear feeding mechanism 3. A packaging heat-sealing mechanism 6 is positioned between the discharge port 12 and the front feeding mechanism 2. When the visual inspection mechanism 4 detects a defective chip capacitor B, the first cutting mechanism 5 can cut and separate the cavity A1 containing the defective capacitor from the carrier tape A. Then, the front feeding mechanism 2 and the rear feeding mechanism 3 respectively drive the two cut sections of carrier tape A to continue forward transport, thereby pushing the separated cavity A1 to the discharge port 12 for discharge. Finally, the packaging heat-sealing mechanism 6 heat-presses and fixes the packaging tape C onto the two cut sections of carrier tape A, ensuring that the two cut sections of carrier tape A remain connected through the packaging tape C. This achieves the purpose of defective product screening during the packaging process of the chip capacitor B.

[0032] Specifically, such as Figure 9 As shown, the carrier tape receiving method of the capacitor base board machine includes the following steps: Step 1: Control the front feeding mechanism 2 and the rear feeding mechanism 3 to drive the carrier belt A forward on the conveying base 1, so that the carrier belt A passes through the vision inspection mechanism 4, the first cutting mechanism 5 and the packaging heat sealing mechanism 6 in sequence. The vision inspection mechanism 4 performs visual inspection on the chip capacitor B in the carrier belt A, and the packaging heat sealing mechanism 6 heat-presses and fixes the packaging tape C on the carrier belt A. Step 2: When the visual inspection mechanism 4 detects a surface mount capacitor B with a defective appearance, proceed to steps 3-5. When the visual inspection mechanism 4 does not detect a surface mount capacitor B with a defective appearance, repeat steps 1 and 2. Step 3: Control the front-end feeding mechanism 2 and the rear-end feeding mechanism 3 to transport the cavity A1 containing the defective capacitor in the carrier tape A to the first cutting mechanism 5; Step 4: Control the first cutting mechanism 5 to cut and separate the cavity A1 containing the defective capacitor from the carrier tape A; Step 5: Control the front-end feeding mechanism 2 and the rear-end feeding mechanism 3 to drive the two cut sections of carrier tape A to continue to convey forward, so as to push the cavity A1 containing the defective capacitor to the discharge port 12 for discharge, and convey the two cut sections of carrier tape A to the packaging heat sealing mechanism 6, where the packaging heat sealing mechanism 6 heat-presses and fixes the packaging tape C onto the two cut sections of carrier tape A.

[0033] In step 5, the front-end feeding mechanism 2 and the rear-end feeding mechanism 3 can feed synchronously at the same speed. At this time, there is a gap between the two cut sections of carrier tape A when they arrive at the packaging heat-sealing mechanism 6. This gap is equal to the length of a single hole A1. Alternatively, the front-end feeding mechanism 2 and the rear-end feeding mechanism 3 can feed synchronously at different speeds, with the feeding speed of the front-end feeding mechanism 2 being less than that of the rear-end feeding mechanism 3. This reduces the gap between the two cut sections of carrier tape A when they arrive at the packaging heat-sealing mechanism 6. The front-end feeding mechanism 2 can also first transport one section of the carrier tape at the front end to the packaging heat-sealing mechanism 6, and then the rear-end feeding mechanism 3 can transport the other section of the carrier tape at the rear end to the packaging heat-sealing mechanism 6. This also adjusts the gap between the two cut sections of carrier tape A when they arrive at the packaging heat-sealing mechanism 6.

[0034] like Figure 4 As shown, the front-end feeding mechanism 2 includes a front-end driver 21, a front-end rotating shaft 22, two front-end feed rollers 23, and a front-end rotary encoder 24. The conveying base 1 extends two front-end connecting parts 13 at one end near the front-end feeding mechanism 2, and the conveying groove 11 is located between the two front-end connecting parts 13. The two ends of the front-end rotating shaft 22 are respectively connected to the two front-end connecting parts 13, and the two front-end feed rollers 23 are arranged opposite to each other on the front-end rotating shaft 22 with their gap aligned with the conveying groove 11. The front-end driver 21 drives the front-end rotating shaft 22 to rotate, and the front-end rotary encoder 24 is disposed on the front-end rotating shaft 22.

[0035] like Figure 5As shown, the rear feeding mechanism 3 includes a rear driver 31, a rear rotating shaft 32, two rear feed rollers 33, and a rear rotary encoder 34. The conveying base 1 extends two rear connecting parts 14 at one end near the rear feeding mechanism 3, and the conveying groove 11 is located between the two rear connecting parts 14. The two ends of the rear rotating shaft 32 are respectively connected to the two rear connecting parts 14, and the two rear feed rollers 33 are arranged opposite to each other on the rear rotating shaft 32 with their gap aligned with the conveying groove 11. The rear driver 31 drives the rear rotating shaft 32 to rotate, and the rear rotary encoder 34 is disposed on the rear rotating shaft 32.

[0036] In this embodiment, both the front-end driver 21 and the rear-end driver 31 are drive motors.

[0037] Before the first cutting mechanism 5 cuts the carrier belt A, and after the packaging heat sealing mechanism 6 heat-presses and fixes the packaging belt C onto the two cut sections of carrier belt A, the front feeding mechanism 2 and the rear feeding mechanism 3 simultaneously convey the entire carrier belt A forward. At this time, the rotational synchronization requirements between the front feeding wheel 23 and the rear feeding wheel 33 are relatively high.

[0038] To reduce the synchronization requirements between the front feed roller 23 and the rear feed roller 33, the outer periphery of the rear feed roller 33 is provided with spaced belt guide pins 331, which are embedded in the positioning hole A2 of the carrier belt A to drive the carrier belt A forward; the outer periphery of the rear feed roller 33 is not provided with any belt guide pins 331, so that the carrier belt A is driven forward by friction.

[0039] Before the first cutting mechanism 5 cuts the carrier tape A, and after the packaging heat-sealing mechanism 6 heat-presses the packaging tape C onto the two cut sections of carrier tape A, the rear feed roller 33 drives the entire carrier tape A forward by the pushing force of the pushing needle 331 on the carrier tape A, while the front feed roller 23 drives the entire carrier tape A forward by the friction of its own surface. Since the pushing force of the rear feed roller 33 is greater than the friction of the front feed roller 23, the conveying length of the entire carrier tape A is determined by the number of rotations of the rear feed roller 33.

[0040] After the first cutting mechanism 5 cuts the carrier belt A, the rear feed roller 33 drives a section of carrier belt A at the rear end to be conveyed forward by the pushing force of the pull pin 331. The front feed roller 23 drives another section of carrier belt A at the front end to be conveyed forward by the friction of its own surface. The conveying length of the section of carrier belt A at the rear end is determined by the number of rotations of the rear feed roller 33, and the conveying length of the other section of carrier belt A at the front end is determined by the number of rotations of the front feed roller 23.

[0041] Therefore, after the first cutting mechanism 5 cuts the carrier tape A, the conveying length of the front section of carrier tape A is positioned according to the number of revolutions measured by the front rotary encoder 24, and the conveying length of the rear section of carrier tape A is positioned according to the number of revolutions measured by the rear rotary encoder 34; before the first cutting mechanism 5 cuts the carrier tape A, and after the packaging heat-sealing mechanism 6 heat-presses and fixes the packaging tape C onto the two cut sections of carrier tape A, the conveying length of the entire carrier tape A is positioned according to the number of revolutions measured by the rear rotary encoder 34.

[0042] Preferably, the front-end feeding mechanism 2 further includes a pressure roller 25 and a first lifting assembly 26. The pressure roller 25 is located above the front-end feeding roller 23 and is disposed on the first lifting assembly 26. The first lifting assembly 26 drives the pressure roller 25 to rise and fall relative to the front-end feeding roller 23. When the first lifting assembly 26 drives the pressure roller 25 to descend and approach the front-end feeding roller 23, the pressure roller 25 presses the carrier belt A, which is fixed with the packaging belt C, onto the front-end feeding roller 23. When the first lifting assembly 26 drives the pressure roller 25 to rise and move away from the front-end feeding roller 23, the pressure roller 25 releases the carrier belt A, which is fixed with the packaging belt C.

[0043] Before the first cutting mechanism 5 cuts the carrier belt A, and after the packaging heat-sealing mechanism 6 heat-presses and fixes the packaging belt C onto the two cut sections of carrier belt A, the first lifting component 26 drives the pressure roller 25 to rise away from the front feed roller 23 to reduce the friction between the front feed roller 23 and the carrier belt A; after the first cutting mechanism 5 cuts the carrier belt A, the first lifting component 26 drives the pressure roller 25 to descend and approach the front feed roller 23 to increase the friction between the front feed roller 23 and the carrier belt A.

[0044] In this embodiment, the first lifting component 2 is a cylinder guide rail component.

[0045] like Figure 6As shown, the first cutting mechanism 5 includes a first pair of scissors 51, a first cutting driver 52, a first translation component 53, and a first cutting bracket 54. The first cutting bracket 54 is connected to one side of the conveying base 1, and the first translation component 53 is disposed on the first cutting bracket 54. The first scissors 51 and the first cutting driver 52 are disposed on the first translation component 53. The first translation component 53 drives the first scissors 51 to translate relative to the conveying base 1. When the first translation component 53 drives the first scissors 51 to translate closer to the conveying base 1, the first scissors 51 extends into the conveying groove 11 of the conveying base 1. When the first translation component 53 drives the first scissors 51 to translate away from the conveying base 1, the first scissors 51 extends out of the conveying groove 11 of the conveying base 1. The first cutting driver 52 is connected to drive the first scissors 51 to cut.

[0046] In step 3 of the carrier tape receiving method, the front-end feeding mechanism 2 and the rear-end feeding mechanism 3 are controlled to transport one end of the cavity portion A1 containing the defective capacitor to the first cutting mechanism 5; in step 4, the first cutting mechanism 5 is first controlled to cut off one end of the cavity portion A1 containing the defective capacitor, then the rear-end feeding mechanism 3 is controlled to transport the other end of the cavity portion A1 containing the defective capacitor to the first cutting mechanism 5, and then the first cutting mechanism 5 is controlled to cut off the other end of the cavity portion A1 containing the defective capacitor.

[0047] In this embodiment, the first cut-off driver 52 is a drive cylinder, and the first translation component 53 is a cylinder guide rail component.

[0048] like Figure 7 As shown, the packaging heat-sealing mechanism 6 includes a belt feeding pulley 61, multiple guide rollers 62, a belt feeding guide 63, a heat-sealing pressure head 64, a second lifting assembly 65, and a heat-sealing bracket 66. The heat-sealing bracket 66 is connected to one side of the conveyor base 1. The belt feeding pulley 61, multiple guide rollers 62, and the second lifting assembly 65 are all mounted on the heat-sealing bracket 66. The heat-sealing pressure head 64 is mounted on the second lifting assembly 65 and is driven by the second lifting assembly 65 to move up and down relative to the conveyor base 1. When the second lifting assembly 64... When the heat-sealing head 64 descends and approaches the conveyor base 1, the heat-sealing head 64 presses the packaging tape C tightly onto the carrier tape A. When the second lifting component 65 drives the heat-sealing head 64 to rise away from the conveyor base 1, the heat-sealing head 64 releases the packaging tape C and the carrier tape A. The tape feeding guide 63 is disposed on the conveyor base 1 and is located on the side of the heat-sealing head 64 near the first cutting mechanism 5, so as to guide the packaging tape C to enter the heat-sealing head 64 parallel to the carrier tape A.

[0049] In this embodiment, the second lifting component 65 is a cylinder guide rail component.

[0050] The visual inspection mechanism 4 includes a ring light source 71, a CCD camera 72, and an inspection bracket 73. The inspection bracket 73 is connected to the heat-sealing bracket 66 on the side near the first cutting mechanism 5 and extends from above the first cutting mechanism 5 to the inspection station. The ring light source 71 and the CCD camera 72 are disposed on one end of the inspection bracket 73 extending to the inspection station, and the CCD camera 72 is located above the ring light source 71 and aligned with the ring light source 71 along the optical axis.

[0051] like Figure 6 and 7 As shown, the conveying base 1 is provided with a baffle 15 at a position corresponding to the visual inspection mechanism 4. The baffle 15 covers and shields a partial area of ​​the conveying groove 11 and is provided with a detection hole 151 to expose a single chip capacitor B in the carrier tape A, so that the visual inspection mechanism 4 can only capture the chip capacitor B exposed from the detection hole 151 each time, so as to locate the defective capacitor.

[0052] The baffle 15 extends to cover the discharge port 12 and is provided with a clearance groove 152 corresponding to the first cutting mechanism 5. This is to prevent the cut-off hole A1 from being pushed upwards due to the compression of the two sections of carrier tape A, or even from falling out of the conveying groove 11, during the process of the front feeding mechanism 2 and the rear feeding mechanism 3 driving the two cut sections of carrier tape A forward, and pushing the hole A1 containing the defective capacitor to the discharge port 12. This ensures that the cut-off hole A1 can be discharged from the discharge port 12.

[0053] Preferably, a collection box (not shown in the figure) or a collection funnel (not shown in the figure) connected to the collection box may be provided below the conveying base 1 to collect the discharged cavity A1.

[0054] like Figure 1 As shown, the carrier tape receiving device further includes: The second cutting mechanism 7 is located on the side of the front feeding mechanism 2 away from the packaging heat sealing mechanism 6, and is used to cut the carrier tape A that has been heat-sealed with the packaging tape C; The receiving mechanism 8 is located on the side of the second cutting mechanism 7 away from the front feeding mechanism 2, and is used to wind up the carrier tape A that is heat-sealed with the packaging tape C.

[0055] like Figure 10As shown, in step 1 of the carrier tape take-up method of the capacitor base plate machine, after the carrier tape A passes through the vision inspection mechanism 4, the first cutting mechanism 5 and the packaging heat sealing mechanism 6 in sequence, it also passes through the second cutting mechanism 7 and the take-up mechanism 8 in sequence. The second cutting mechanism 7 cuts the carrier tape A with the packaging tape C heat-sealed, and the take-up mechanism 8 winds up the carrier tape A with the packaging tape C heat-sealed.

[0056] like Figure 8 As shown, the second cutting mechanism 7 includes a second pair of scissors 71, a second cutting driver 72, a second translation component 73, two roller sets 74, and a second cutting bracket 75. The second cutting bracket 75 is connected to one side of the conveying base 1. The two roller sets 74 are rotatably mounted on the second cutting bracket 75. The second translation component 73 is mounted on the second cutting bracket 75, and the second scissors 71 and the second cutting driver 72 are mounted on the second translation component 73. The second translation component 73 drives the second scissors 71 to translate relative to the two roller sets 74. When the second translation component 73 drives the second scissors 71 to translate closer to the two roller sets 74, the second scissors 71 extends into the gap between the two roller sets 74. When the second translation component 73 drives the second scissors 71 to translate away from the two roller sets 74, the second scissors 71 extends out of the gap between the two roller sets 74. The second cutting driver 72 drives the second scissors 71 to cut.

[0057] In this embodiment, the second translation component 73 is a cylinder guide rail component.

[0058] The receiving mechanism 8 includes a receiving tray 81, a receiving driver 82, a receiving sensor 83, and a receiving bracket 84. The receiving bracket 84 is connected to the second cutting bracket 75. The receiving tray 81 is rotatably mounted on the receiving bracket 84. The receiving driver 82 drives the receiving tray 81 to rotate. The receiving sensor 83 is mounted on the receiving bracket 84 and is used to detect the thickness or length of the carrier tape A in the receiving tray 81. When the thickness or length of the carrier tape A in the receiving tray 81 reaches a preset value, the second cutting mechanism 7 cuts the carrier tape A that is heat-sealed with the packaging tape C.
