Description

Technical Field

[0002] An antistatic tape is a tape specially designed to prevent the accumulation of static electricity. It is commonly used in the processes of electronic product manufacturing, packaging, assembly, etc., especially in environments sensitive to static electricity. Its characteristic is that it can effectively prevent the damage of static electricity to equipment or components. Especially when dealing with precision electronic equipment such as semiconductors and printed circuit boards (PCBs), static electricity may cause damage to components or a decline in product quality. Common materials of antistatic tapes include polyester (PET), polypropylene (PP), polyethylene (PE), etc., which have good mechanical strength and antistatic performance. In addition, some antistatic tapes add conductive components to the adhesive layer to enhance their antistatic effect.

[0003] Static electricity can adsorb tiny dust particles in the air, which may cause serious problems in the process of electronic manufacturing. Dust particles will interfere with the performance of electronic components and even cause malfunctions, especially when dealing with precision semiconductors, microelectronic devices or integrated circuits. The antistatic tape reduces or eliminates surface static electricity through its antistatic characteristics, thereby effectively preventing dust from adhering to sensitive equipment and components. During the application process of the antistatic tape, in order to improve the adhesion of the antistatic tape and reduce the impact of dust particles on electronic devices, the paste surface needs to be dusted before pasting.

[0028] Please refer to Figures 1 to 4, the antistatic tape assembly disclosed by the present utility model includes an antistatic tape 100, a housing 200, a tape unwinding mechanism 300, a cutting mechanism 400, and a dustproof mechanism 500. The tape unwinding mechanism 300, the cutting mechanism 400, and the dustproof mechanism 500 are installed inside the housing 200, and the antistatic tape 100 is installed on the tape unwinding mechanism 300. Among them, the housing 200 is provided with an output port, the output port is arranged at one end of the housing 200, the cutting mechanism 400 is arranged at the output port, and the free end of the antistatic tape 100 extends to the outside of the housing 200 through the output port. Thus, the cutting mechanism 400 can cut off the antistatic tape 100 at the output port to ensure the convenience of using the antistatic tape 100. Specifically, the dustproof mechanism 500 includes a fan unit 510, an air flow channel 520, a dust collection chamber 530, and a filter screen 540. The filter screen 540 is arranged at the bottom side of the output port and connected to the bottom wall of the housing 200. One end of the air flow channel 520 is connected to the filter screen 540, and the other end of the air flow channel 520 extends a preset distance along the bottom wall of the housing 200 and is connected to the dust collection chamber 530. The dust collection chamber 530 is installed at the bottom of the housing 200, and the fan unit 510 is installed and communicated with the top of the dust collection chamber 530. Thus, under the drive of the fan unit 510, a preset-direction air flow is generated in the air flow channel 520, prompting a negative pressure to be formed at the filter screen 540 to suck dust particles with a preset particle size or less at the output port. The filter screen 540 can prevent large-particle-size particles from the outside from being inhaled into the air flow channel 520 and causing blockage. Then, the dust particles are input into the dust collection chamber 530 through the air flow channel 520 for temporary storage. In this way, during the use of the antistatic tape assembly, the dustproof mechanism 500 can remove dust from the tape sticking surface, improving the bonding force between the antistatic tape 100 and the tape sticking surface while further enhancing the effectiveness of the antistatic function of the antistatic tape 100.

[0029] Furthermore, the dustproof mechanism 500 further includes a dustproof net 550 and a door body 560. The dustproof net 550 is arranged on the top side of the dust collection chamber 530 to prevent, and the surface of the side of the dustproof net 550 facing away from the dust collection chamber 530 is correspondingly matched with the fan unit 510. Thus, the dustproof net 550 can effectively prevent the dust particles inside the dust collection chamber 530 from entering the housing 200 through the fan and affecting the normal operation of other functional mechanisms, and can also prevent the dust particles from adhering to the surface of the antistatic tape 100. The door body 560 is arranged on the bottom wall of the housing 200 corresponding to the dust collection chamber 530. Thus, the dust collection chamber 530 can be communicated to the outside of the housing 200 through the door body 560. When the antistatic tape assembly stops being used, the inside of the dust collection chamber 530 can be cleaned by opening the door body 560 to keep the inside of the dust collection chamber 530 clean.

[0030] Further, the unwinding mechanism 300 includes an unwinding roller 310, a delivery roller 320, a guiding assembly 330, a transmission assembly 340, and a control handle 350. Among them, the unwinding roller 310 is rotatably arranged in the middle of the housing 200; the delivery roller 320 is arranged on one side of the unwinding roller 310 facing the output port; the guiding assembly 330 is sleeved on the side surface of the delivery roller 320 and extends to the output port; one end of the transmission assembly 340 is connected to the delivery roller 320 in a mating manner, and the other end of the transmission assembly 340 extends to the other end of the housing 200 and is connected to the control handle 350, and the control handle 350 is movably connected to the housing 200 and extends to the outside of the housing 200. The antistatic tape 100 is fitted and installed on the unwinding roller 310, and the free end of the antistatic tape 100 is conveyed through the side surface of the delivery roller 320 and extends to the output port under the guidance of the guiding assembly 330. When the control handle 350 is pressed, the delivery roller 320 is driven to rotate through the transmission assembly 340, and the free end of the antistatic tape 100 is driven by the side surface of the delivery roller 320 to move toward the output port under the guidance of the guiding assembly 330. At this time, the unwinding roller 310 rotates and unwinds accordingly, thereby realizing the unwinding function of the unwinding mechanism 300.

[0031] Specifically, the transmission assembly 340 includes a transmission plate 341 and a double gear 342. The double gear 342 is rotatably connected to the inner wall of the housing 200 corresponding to the control handle 350. The inner gear of the double gear 342 meshes with one end of the control handle 350, and the outer gear of the double gear 342 meshes with one end of the transmission plate 341. The other end of the transmission plate 341 extends along the inner wall of the housing 200 for a preset distance and meshes with the delivery roller 320 correspondingly. Thus, the control handle 350 can drive the delivery roller 320 to rotate sequentially through the double gear 342.

[0032] Further, the delivery roller 320 is provided with a driven gear 321 and an internal meshing ratchet mechanism. The driven gear 321 and the internal meshing ratchet mechanism are sleeved on the end of the rotating shaft of the delivery roller 320 in sequence. Among them, the driven gear 321 meshes with one end of the transmission plate 341 correspondingly; the ratchet 322 of the internal meshing ratchet mechanism is connected to the end of the delivery roller 320, and the pawl 323 is fitted inside the ratchet 322 and connected to the side surface of the driven gear 321. Thus, when the transmission plate 341 drives the driven gear 321 to rotate in a preset direction, the driven gear 321 drives the pawl 323 to rotate, and then the pawl 323 engages with the ratchet 322 and drives the delivery roller 320 to rotate in a preset direction. When the transmission plate 341 drives the driven gear 321 to rotate reversely, the pawl 323 disengages from the ratchet 322, thereby preventing the delivery roller 320 from rotating reversely.

[0033] Further, the cutting mechanism 400 includes a cutting blade 410, a tool holder 420, a first drive shaft 430, a second drive shaft 440, and an elastic member 450; the tool holder 420 is disposed at the output port; the cutting blade 410 is slidably engaged with the tool holder 420; the first drive shaft 430 is disposed adjacent to the end of the transmission plate 341 facing the output port, and the first drive shaft 430 is correspondingly engaged with the end of the transmission plate 341; the second drive shaft 440 is disposed adjacent to the first drive shaft 430, and the second drive shaft 440 is correspondingly engaged with the first drive shaft 430; the second drive shaft 440 is drivingly connected to the cutting blade 410; one end of the elastic member 450 is connected to the inner wall of the housing 200, and the other end of the elastic member 450 is connected to the second drive shaft 440. Thus, when the operating handle 350 is pressed and the delivery roller 320 performs the delivery work, the end of the transmission plate 341 drives the first drive shaft 430 to rotate, the first drive shaft 430 drives the second drive shaft 440 to rotate, and then, the second drive shaft 440 drives the cutting blade 410 to rise along the tool holder 420. At this time, the elastic member 450 is compressed and stores energy, and the free end of the antistatic tape 100 can be pulled out to any length through the output port; when the operating handle 350 is reset, the transmission plate 341, the first drive shaft 430, and the second drive shaft 440 move reversely, and the elastic member 450 is reset accordingly, and then the cutting blade 410 is reset along the tool holder 420 to cut the antistatic tape 100.

[0034] Specifically, a first abutting block a is provided at one end of the transmission plate 341 that cooperates with the first drive shaft 430. When the transmission plate 341 moves in the preset direction, the first abutting block a cooperates with and abuts against the first drive shaft 430 to urge the first drive shaft 430 to rotate in the preset direction; correspondingly, a second abutting block b is provided at one end of the first drive shaft 430 that cooperates with the transmission plate 341. When the transmission plate 341 drives the first drive shaft 430 to rotate, the first abutting block a cooperates with and abuts against the second abutting block b to urge the second abutting block b to abut against and cooperate with the second drive shaft 440 to urge the second drive shaft 440 to rotate in the preset direction; correspondingly, a third abutting block c is provided at one end of the second drive shaft 440 that cooperates with the second abutting block b. Thus, the first drive shaft 430 cooperates with and abuts against the third abutting block c through the second abutting block b, thereby realizing the cooperative linkage of the transmission plate 341, the first drive shaft 430, and the second drive shaft 440.

[0035] Further, a connecting plate 441 is provided on the side surface of the second drive shaft 440, and the connecting plate 441 is cooperatively connected to the cutting blade 410. Thus, when the second drive shaft 440 rotates, it can drive the cutting blade 410 to reciprocate along the tool holder 420 through the connecting plate 441. Specifically, one end of the elastic member 450 connected to the second drive shaft 440 is connected to one side of the connecting plate 441 to facilitate the elastic member 450 to drive the second drive shaft 440 to reset.

[0036] In summary, the antistatic tape assembly disclosed by the present utility model extends the free end of the antistatic tape to the outside of the housing through the output port of the housing. Thus, the cutting mechanism can cut off the antistatic tape at the output port, thereby ensuring the convenience of using the antistatic tape. The dust-proof mechanism includes a fan unit, an air flow channel, a dust collection chamber, and a filter screen. The filter screen is arranged at the bottom side of the output port and connected to the bottom wall of the housing; one end of the air flow channel is connected to the filter screen, and the other end of the air flow channel extends a preset distance along the bottom wall of the housing and is connected to the dust collection chamber; the dust collection chamber is installed at the bottom of the housing, and the fan unit is installed and communicated with the top of the dust collection chamber. Thus, under the drive of the fan unit, the air flow channel generates an air flow in a preset direction, promoting the formation of negative pressure at the filter screen to suck dust particles with a particle size below a preset size at the output port. The filter screen can prevent large-sized external particles from being inhaled into the air flow channel and causing blockage. Then, the dust particles are input into the dust collection chamber through the air flow channel for temporary storage. Therefore, during the use of the antistatic tape assembly, the dust-proof mechanism can remove dust from the tape sticking surface, while improving the bonding force between the antistatic tape and the tape sticking surface, and further enhancing the effectiveness of the antistatic function of the antistatic tape.

For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.
