Description

Technical Field

[0001] This utility model relates to the field of pressure sensor technology, specifically a carrier device that uses a probe adapter to read ID. Background Technology

[0002] In traditional pressure sensor designs, the chip used to store calibration data, identification information (ID), or other parameter information is typically mounted directly inside the sensor housing. This mounting method ensures the stability and consistency of the chip's position, facilitating accurate alignment and data reading by external reading devices, and guaranteeing the reliability and efficiency of data communication.

[0003] However, with the continuous optimization of pressure sensor structures and further reduction in size, the internal housing can no longer provide sufficient space for the chip's fixed installation. Therefore, the design had to relocate the chip to a flexible flat panel cable (FPC) extending outwards from the pressure sensor. While FPCs offer advantages such as flexible wiring, bendability, and adaptability to complex spaces, their soft material makes their shape and position susceptible to influences from the installation environment, vibration, or movement, making it difficult to maintain a fixed position.

[0004] Because the position and shape of the flexible flat cable are not fixed, the chip will shift or change its orientation, making it difficult for the external reading device to accurately and stably align with the chip, thus causing reading failure.

[0005] Therefore, how to ensure that the chip mounted on the flexible flat cable can be read quickly, accurately and stably by the reading device while miniaturizing the pressure sensor has become an urgent problem to be solved by those skilled in the art. Utility Model Content

[0006] To address the technical problems in the background art, this utility model discloses a carrier device that uses a probe to transfer and read ID.

[0008] The chip is mounted on an external PCB board.

[0009] Furthermore, the present invention also includes a pressing component; the pressing component includes a pressing block and a pressing cylinder for driving the pressing block to rise and fall, pressing downward or away from the external PCB board.

[0010] Furthermore, the read probes of the read chip are located below the external PCB board; the conductive layer of the flexible flat cable is located on the lower side.

[0011] Furthermore, the reading probe is mounted on the lifting assembly; the lifting assembly includes a lifting block and a lifting cylinder that drives the lifting block to move up and down; the reading probe is mounted on the upper end of the lifting block.

[0012] Furthermore, the carrier is equipped with an adapter probe for reading the chip; the signal output end of the adapter probe extends to the lower region of the carrier; when the reading probe rises, it contacts the adapter probe and receives the data from the adapter probe.

[0013] Furthermore, the vehicle is provided with vertically extending insertion holes; the adapter probe is inserted into the insertion holes.

[0014] Furthermore, the vehicle is provided with positioning holes; the lifting block is provided with positioning pins that engage with the positioning holes.

[0018] The beneficial effects of the utility model are:

[0019] 1.

[0032] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0033] like Figure 1As shown, this utility model discloses a carrier device for reading ID using a probe adapter, including a carrier 1. The carrier 1 is provided with multiple evenly distributed snap-fit ​​structures for snap-fitting and loading pressure sensor 2, thereby positioning the pressure sensor 2 and conveying it on a conveyor 3 to realize the workstation conversion for processing pressure sensor 2.

[0034] The pressure sensor 2 has an external lead-out flexible flat cable 4, the outer end of which is connected to an external PCB board 6. The chip 5 is mounted on the upper part of the external PCB board 6. Figure 2-5 As shown, the snap-fit ​​structure includes a snap-fit ​​hole 40 on the carrier 1 and a snap-fit ​​base 24 mounted on the carrier 1 adjacent to the snap-fit ​​hole 40. A recessed snap-fit ​​platform 21 is provided at the center of the upper end of the snap-fit ​​base 24, and the external PCB board 6 is snapped into the snap-fit ​​platform 21. Moreover, two symmetrically arranged, protruding protrusions 22 are provided on the side of the snap-fit ​​platform 21, and the outer side of the external PCB board 6 is provided with a snap-fit ​​groove 23 for snapping the protrusions 22. This arrangement realizes the installation limit of the external PCB board 6 and improves its positional stability.

[0035] To facilitate the connection of the external PCB board 6 to the card holder 21, the card holder 21 extends through both sides of the card base 24 in the direction of the extension of the flexible flat cable 4.

[0036] Because the flexible flat cable 4 generates elasticity when excessively compressed or stretched, this elasticity can affect the positional stability of the external PCB board 6. Therefore, the mounting bracket 24 is provided with two symmetrically arranged elongated oval mounting holes 25, the length direction of which is parallel to the extension direction of the flexible flat cable 4. This arrangement allows the position of the mounting bracket 24 to be adjusted, thereby adjusting the tightness of the flexible flat cable 4 and eliminating the elasticity generated by the flexible flat cable 4 when the external PCB board 6 is installed.

[0037] To facilitate the assembly and disassembly of the external PCB board 6, the external PCB board 6 and the card holder 24 are generally loosely fitted. When reading the ID, the external PCB board 6 is prone to misalignment. Therefore, this embodiment also provides a pressing component 7, which is equipped with a pressure block 8 to press and fix the external PCB board 6, so that the position of the external PCB board 6 remains stable when reading the ID of the chip 5.

[0038] The specific structure of the downward pressure component 7 is as follows: Figure 7As shown, the system includes two symmetrically arranged fixed seats 26, fixedly installed on one side of the conveyor 3 frame. An upwardly extending adjusting column 18 is mounted on the fixed seat 26, and a slidingly connected adjusting block 20 is sleeved on the adjusting column 18. One side of the adjusting block 20 has a slot communicating with a connecting hole. A bolt passes through the portion of the adjusting block 20 located on one side of the slot and is threadedly connected to the portion on the other side of the slot, thus connecting and fixing the adjusting block 20 to the adjusting column 18. This also allows the height of the adjusting block 20 to be adjusted. A vertically arranged adjusting plate 19 is fixedly installed on the side of the adjusting block 20 facing the conveyor 3. A downward pressing cylinder 9 is installed at the center of the upper end of the adjusting plate 19, with its driving end facing downwards. Linear guide rails 27 are symmetrically arranged on both sides of the downward pressing cylinder 9. A downward pressing seat 28 is fixedly installed on the slider of the linear guide rail 27, and a horizontally arranged pressing block 8 is installed at the lower end of the downward pressing seat 28. Figure 8 As shown, the lower end of the pressure block 8 is provided with multiple spaced, evenly distributed pressure parts 29 corresponding to each external PCB board 6. The lower end of the pressure part 29 is provided with four contact parts 30 arranged in a rectangular shape. The contact parts 30 contact the external PCB board 6 and avoid the chip 5.

[0039] Different models of pressure sensors 2 require different matching external PCB boards 6 and carriers 1. Therefore, a mounting block 15 is provided at the lower end of the lower pressure base 28. The lower end of the mounting block 15 has a U-shaped, downward-facing, horizontally extending mounting groove 16, and the upper end of the pressure block 8 is engaged in the mounting groove 16. Two symmetrically arranged horizontal pins 17 are inserted into the pressure block 8 and the mounting block 15 to fix the pressure block 8 to the mounting block 15 and to allow for quick assembly and disassembly of the pressure block 8 and the mounting block 15. When replacing different models of pressure sensors 2, the matching pressure block 8 can be installed through quick assembly and disassembly, thus making this embodiment applicable to different models of pressure sensors 2.

[0040] Under the action of the pressing component 7, there is insufficient space above the chip 5 to install the reading probe 32 for reading the ID of the chip 5. Therefore, the reading probe 32 is installed below the chip 5 and is lifted and lowered by the lifting component 10. Correspondingly, the conductive layer of the external PCB board 6 is located on the lower side of the external PCB board 6. The specific installation structure of the lifting component 10 is as follows: Figure 9As shown, the system includes a U-shaped lifting seat 41 with its opening facing upwards. The upper end of the lifting seat 41 is fixedly connected to the lower end of the conveyor frame 3. A lifting cylinder 42 is fixedly installed on the upper side of the flat plate at the lower end of the lifting seat 41. The drive end of the lifting cylinder 42 faces upwards and is fixedly connected to the lifting plate 34. Symmetrically arranged linear bearings 35 are installed on the flat plate on both sides of the lifting cylinder 42. Guide posts 36 are inserted into the linear bearings 35. The upper ends of the guide posts 36 are fixedly connected to the lower end of the lifting plate 34 for guiding the lifting of the lifting plate 34. Multiple lifting blocks 11 corresponding to the pressure sensors 2 are installed on the upper end of the lifting plate 34. A reading probe 32 is installed on the upper end of the lifting block 11. When the reading probe 32 rises, it abuts against the conductive layer of the external PCB board 6 to read the ID of the chip 5.

[0041] Due to the function of the card slot 24, the distance between the external PCB board 6 and the reading probe 32 is relatively far, making it difficult for the reading probe 32 to contact the external PCB board 6. Therefore, as Figure 6 As shown, a pin holder 43 is mounted on the lower end of the card holder 24. The pin holder 43 has a through-hole 12. The adapter probe 33 is inserted into the pin sleeve, which is in turn inserted into the through-hole 12. The pin holder 43 is made of plastic, which facilitates deformation, and it is connected to the pin sleeve with an interference fit. The friction generated by the pin holder fixes the position of the adapter probe 33. The lower end of the probe extends to a position close to the lower end of the card holder 24. The upper end of the adapter probe 33 abuts against the conductive layer on the lower side of the external PCB board 6 to read the ID of the chip 5. When the read probe 32 rises, its upper end abuts against the lower end of the adapter probe 33 to establish a signal connection, thereby transferring the ID data on the adapter probe 33 to the read probe 32.

[0042] To ensure that the reading probe 32 accurately abuts the lower end of the adapter probe 33, the lifting plate 34 is provided with upwardly extending side plates 37 at both ends, and the upper end of the side plates 37 is provided with a protruding positioning post 14; the two sides of the card holder 24 are provided with positioning holes 13 for engaging the positioning post 14. The upper end of the positioning post 14 is provided with a chamfer for guiding the positioning post 14 upward, so that it can be stably inserted into the positioning hole 13.

[0043] A blocking block 38 is installed on the frame of conveyor 3, which is driven by a blocking cylinder 39 installed on the frame to move up and down. When the blocking block 38 rises, it is higher than the lower end of the carrier 1, which blocks the carrier 1 and prevents it from moving forward. This positions the carrier 1 directly below the pressing component 7, thus completing the ID reading of the chip 5.

[0044] The working principle of this embodiment is as follows:

[0045] 1. When the carrier 1 moves to the bottom of the pressing component 7, the blocking cylinder 39 drives the blocking block 38 to rise and block the carrier 1.

[0046] 2. The lifting cylinder 42 drives the lifting plate 34 to rise, so that the positioning pin 14 is inserted into the positioning hole 13, and the upper end of the reading probe 32 abuts against the lower end of the transfer probe 33, transferring the ID of the chip 5 read by the transfer probe 33 to the reading probe 32, thereby completing the reading of the ID of the chip 5 of the pressure sensor 2.

[0047] 3. The downward pressure cylinder 9 drives the pressure block 8 to descend, pressing and fixing the external PCB board 6;

[0048] 4. The pressing cylinder 9, lifting cylinder 42 and blocking cylinder 39 are reset in sequence, and the carrier 1 moves to the next work station.

[0049] Compared to existing technologies, the advantages of this embodiment are: 1. By fixing the chip 5 at the outer end of the flexible flat cable 4 onto the external PCB board 6 on the carrier 1, the rigid support and positioning characteristics of the external PCB board 6 ensure that the chip 5 maintains a stable position and orientation during transportation, avoiding displacement or deflection of the chip 5 caused by the flexibility and deformation of the flexible flat cable 4. This allows the external reading device to quickly and accurately align and read the data from the chip 5, significantly improving communication reliability and reading success rate. 2. Without occupying the internal space of the sensor housing, this device provides a stable mounting foundation for the chip 5 through the external carrier 1 and the external PCB board 6, perfectly adapting to the trend of smaller size and more compact structure of the pressure sensor 2, while ensuring that the storage and reading functions of key parameters such as calibration data and ID information are not affected.
