[0002] The RFID chip binding process is a key link in the production process of RFID chips to ensure the normal operation of RFID chips. During the production process of the RFID chip binding process, glue coating and curing are required. When winding up after binding, in order to prevent the RFID chips from sticking and damaging the RFID chips when the tightening force is too large, an isolation belt needs to be added to protect the RFID chips. At the same time, in order to improve production efficiency, multiple products are often produced together, so multiple isolation belts are also required.

[0003] When the RFID chips are embedded in the isolation belt, due to factors such as changes in material properties during the manufacturing process or external environmental interference, the isolation belt may break or be damaged. This break may affect the integrity of the RFID chips. Therefore, during this process, it is necessary to detect the broken belt of the isolation belt to ensure the integrity of the RFID chips. Summary of the Utility Model

This broken belt detection device can not only detect whether the isolation belt breaks or is missing after the RFID chips are embedded in the isolation belt, but also can detect the broken belt of multiple isolation belts simultaneously. It avoids the problem that the RFID chips are incomplete due to the broken belt of the isolation belt during winding up. In addition, multiple isolation belts can be detected simultaneously, improving work efficiency.

[0022] Beneficial effects

[0023] 1. The tape break detection device provided by the present utility model is provided with a photoelectric sensor and a blocking part. The blocking part is placed above the isolation tape. When the isolation tape breaks or is missing, the blocking part sags under the action of gravity between the photoelectric sensors, triggering the photoelectric sensors to issue an alarm. When the isolation tape is not broken, the isolation tape is in a tensioned state under the resistance of the material tray and the pulling force of the chip reel, and the blocking part will not sag, and the photoelectric sensors will not be triggered, thereby realizing the tape break detection of the isolation tape.

[0024] 2. The tape break detection device provided by the present utility model can be provided with multiple groups of blocking parts and fixing rings. The blocking parts can move freely on the connecting pieces, and the fixing rings can move freely on the support shafts, thereby solving the problem of quickly adjusting the position of the isolation tape and completing the quick switching between products of different sizes. When the number of required isolation tape lanes decreases, the redundant blocking parts and fixing rings can be moved to one side, and the blocking piece can be flipped above the connecting piece. When the number of required isolation tape lanes increases, multi-row isolation tape simultaneous detection can be achieved by adding fixing rings and blocking parts, thereby improving work efficiency. The tape break detection device provided by the present utility model can be compatible with various sizes and rows, and has a simple structure and is convenient for adjustment.

[0025] 3. The tape break detection device provided by the present utility model further includes fixing rings. The fixing rings are sleeved on the first support shaft and the second support shaft and are located on both sides of the isolation tape, capable of limiting the isolation tape to prevent the isolation tape from slipping along the axis direction of the support shaft during the movement process, affecting the winding of other isolation tapes.

[0037] As Figures 1 to 4 shown, this embodiment provides a belt breakage detection device. The belt breakage detection device 100 is used to detect whether the isolation belt 1 breaks or the isolation belt 1 is missing during the winding process of the RFID chip. The isolation belt 1 is used to isolate and protect the RFID chip during the winding of the RFID chip to ensure the integrity of the RFID chip. Among them, the isolation belt 1 is a strip-shaped product. In this embodiment, siliconized paper is used as the isolation belt 1.

[0038] In some embodiments, the tape break detection device 100 includes a photoelectric sensor 2, a first support shaft 5, a second support shaft 8, a connecting plate 9, and a support base 10. The support base 10 is located at one end of the tape break detection device 100 and is used to provide support for the components of the tape break detection device 100; the connecting plate 9 is located opposite to the support base 10. The number of photoelectric sensors 2 is two, and they are arranged oppositely on the support base 10 and the connecting plate 9, and are used to receive and feedback detection signals. When a tape break or no tape occurs, the photoelectric sensor 2 issues a warning.

[0039] In some embodiments, one end of the first support shaft 5 and the second support shaft 8 is installed on the support base 10 and is respectively rotatably connected to the support base 10. The rotational connection between the first support shaft 5 and the support base 10 is achieved by setting a bearing or the like between them, and the rotational connection between the second support shaft 8 and the support base 10 can also be achieved by setting a bearing. The isolation tape 1 is led out from the material tray, bypasses the first support shaft 5 and the second support shaft 8, and then is introduced into the chip reel. The isolation tape 1 abuts against the first support shaft 5 and the second support shaft 8 respectively. When the chip reel rotates, it drives the isolation tape 1 to move, and the isolation tape 1 drives the first support shaft 5 and the second support shaft 8 to rotate through the friction force between it and the first support shaft 5 and the second support shaft 8. The first support shaft 5 and the second support shaft 8 provide support for the isolation tape 1. Since the mass of the isolation tape 1 is light, the first support shaft 5 and the second support shaft 8 can provide support for it without deformation. Therefore, there is no need to add a support base 10 at the end of the two close to the connecting plate 9, saving production costs.

[0040] In some embodiments, the tape break detection device 100 further includes a fixing ring 4. The fixing ring 4 is sleeved on the outer peripheries of the first support shaft 5 and the second support shaft 8 respectively. The fixing rings 4 are arranged in pairs on both sides of the isolation tape 1 and are used to limit the isolation tape 1 to prevent the isolation tape 1 from moving along the axial directions of the first support shaft 5 and the second support shaft 8 during movement, so as to avoid affecting the movement of other isolation tapes 1.

[0041] In some embodiments, a blocking portion 3, a locking portion 6, and a connecting member 7 are further arranged between the first support shaft 5 and the second support shaft 8. The blocking portion 3 is used to block the photoelectric signal emitted by the photoelectric sensor 2. The blocking portion 3 is fixedly connected to the connecting member 7 through the locking portion 6, and the blocking portion 3 abuts against the isolation tape 1. The connecting member 7 is a solid metal straight bar formed by plastic processing and has a certain cross-sectional shape and size. In the present utility model, the connecting member 7 can be used as a track, and its cross-sectional shape is as Figure 4 shown, and its concave part serves as a track. The two ends of the connecting member 7 are respectively fixedly connected to the support base 10 and the connecting plate 9.

[0042] Further, the blocking portion 3 includes a blocking member 31 and a fixing member 32. One end of the blocking member 31 is rotatably connected to the fixing member 32, enabling the blocking member 31 to rotate. The end of the blocking member 31 facing away from the fixing member 32 abuts against the isolation belt 1, and the blocking member 31 is placed above the isolation belt 1. When the isolation belt 1 is disconnected or missing, the blocking member 31 will drop between the photoelectric sensors 2 under the action of gravity, blocking the signal reception of the photoelectric sensors 2, and the photoelectric sensors 2 will issue a warning. When the isolation belt 1 is not disconnected, due to the resistance of the material tray and the pulling force of the chip reel, the isolation belt 1 is in a tensioned state between the first support shaft 5 and the second support shaft 8. The blocking member 31 is placed on the isolation belt 1 and will not drop, and the photoelectric sensors will not be triggered. A through hole is provided at the end of the fixing member 32 facing away from the blocking member 31, and the locking portion 6 passes through the through hole to fixedly connect the fixing member 32 and the connecting member 7.

[0043] Further, as Figure 5 shown, the locking portion 6 includes a screw 61 and a slider 62. The cross-section of the slider 62 is semi-circular, and a threaded hole is provided inside. The slider 62 is installed in the track of the connecting member 7, and its outer circumferential surface abuts against both side surfaces of the track. The slider 62 can slide freely in the track, thereby realizing the position adjustment of the blocking portion 3. When the slider 62 is adjusted to an appropriate position, screw 61 is screwed in to clamp the fixing member 32 and the connecting member 7 between the screw 61 and the slider 62, and the screw 61 is tightened to fix the fixing member 32 on the connecting member 7.

[0044] In some embodiments, as Figure 6 shown, the fixing ring 4 is an open circular ring structure, and a threaded hole is provided at the opening. The fixing ring 4 is sleeved on the first support shaft 5, and a screw is screwed into the threaded hole. The cooperation relationship between the fixing ring 4 and the first support shaft 5 is controlled by the length of the screw screwed in. When the screw is removed or screwed in too short, the fixing ring 4 has a clearance fit with the first support shaft 5, and the fixing ring 4 can slide on the first support shaft 5. When the fixing ring 4 slides to an appropriate position, the screw is screwed into the threaded hole as a whole to lock the fixing ring 4 on the first support shaft 5. The fixing ring 4 is connected to the second support shaft 8 in the same connection manner.

[0045] Optionally, as Figure 7 shown, the fixing ring 4 can also be a closed ring structure, and the inner diameter of its ring structure is larger than the shaft diameter of the support shaft with which it is used in cooperation. The fixing ring 4 is sleeved on the second support shaft 8 and has a clearance fit with the second support shaft 8, and can slide freely on the second support shaft 8. Threaded holes are provided on the fixing ring 4. Further, the number of threaded holes is at least one. A screw is screwed into the threaded hole until the bottom surface of the screw abuts against the second support shaft 8 to fix the fixing ring 4 on the second support shaft 8. The fixing ring 4 is installed on the first support shaft 5 in the same installation manner.

[0046] In some embodiments, the tape break detection device 100 may also use only one support shaft. However, since the moving speed of the isolation tape 1 is unstable, the isolation tape 1 fluctuates up and down, resulting in the blocking portion 3 sagging and accidentally touching the photoelectric sensor 2, causing the photoelectric sensor 2 to issue an incorrect prompt. In this embodiment, the tape break detection device 100 uses two support shafts, namely the first support shaft 5 and the second support shaft 8, which solves the problem of the blocking portion 3 accidentally touching the photoelectric sensor due to the up and down fluctuation of the isolation tape, and improves the accuracy of the tape break detection device 100.

[0047] Optionally, multiple sets of fixing rings 4 can be provided on the first support shaft 5, and multiple sets of fixing rings 4 can also be provided on the second support shaft 8. The fixing rings 4 need to be provided in pairs and installed on both sides of the isolation tape 1 for limiting the isolation tape 1. By adding multiple sets of fixing rings 4, multiple isolation tapes 1 can be wound simultaneously without interference, enabling the production of multiple rows of products together and improving the winding efficiency.

[0048] Optionally, multiple sets of blocking portions 3 can be provided, which are adapted to the number of fixing rings 4. The blocking portion 3 is slidably connected to the connecting member 7 through the slider 62 of the locking portion 6, which can achieve rapid adjustment of the position of the blocking portion 3 to complete rapid switching between products of different sizes; and when the number of tracks of the isolation tape 1 required for the product changes, as long as the unused blocking portions 3 and fixing rings 4 are moved to one end of the tape break detection device 100, and the blocking portions 3 not on the isolation tape 1 are flipped upward above the connecting member 7.

[0049] The working principle of the present utility model: The isolation tape 1 is led out from the material tray, bypasses the first support shaft 5 and the second support shaft 8 and is introduced into the chip reel. The fixing rings 4 are installed on the outer periphery of the first support shaft 5 and the second support shaft 8 and are distributed on both sides of the isolation tape 1 for limiting the isolation tape 1. The fixing member 32 is connected to the connecting member 7 through the locking portion 6, and the blocking member 31 is rotatably connected to the fixing member 32. The blocking member 31 is placed on the isolation tape 1. When the isolation tape 1 is broken or missing, the blocking member 31 will drop between the photoelectric sensors 2 under the action of gravity, triggering the photoelectric sensor 2 to issue an alarm. When the isolation tape 1 is not broken, due to the resistance of the material tray and the pulling force of the chip reel on the isolation tape 1, the isolation tape 1 is in a tensioned state between the first support shaft 5 and the second support shaft 8, and the blocking member 31 placed on the isolation tape 1 will not drop, and the photoelectric sensor 2 will not be triggered, thereby realizing the detection of the broken tape of the isolation tape.

[0050] The blocking part 3 realizes the position adjustment on the connecting piece 7 through the locking part 6. The fixing ring 4 can also move freely on the first support shaft 5 and the second support shaft 8, so as to realize the quick adjustment of the blocking part 3 and the fixing ring 4 and complete the quick switching between products of different sizes. In addition, when the number of lanes of the isolation belt 1 required by the product decreases, only the redundant blocking part 3 and the fixing ring 4 need to be moved to one end, and the blocking piece 31 is flipped above the connecting piece 7. When the number of lanes of the isolation belt 1 required by the product increases, only the blocking part 3 and the fixing ring 4 need to be increased, so as to realize the breakage detection of multiple rows of isolation belts 1 at the same time and improve the work efficiency. The breakage detection device 100 can be compatible with various sizes and rows, and has a simple structure and is easy to adjust.

[0051] The technical features of the above embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above 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 recorded in this specification.
