[0010] BRIEF DESCRIPTION OF DRAWINGS Figure 2 It is a schematic view of each component of the pressure sensor. DETAILED DESCRIPTION

[0011] The utility model will be further described in connection with the drawings.

[0012] As shown in the utility model of a pressure sensor assembly system in the description, Figure 1 The pressure sensor is assembled by a sensor shell 13, a sealing ring 12 and a ceramic core assembly 11, wherein the ceramic core assembly 11 includes a ceramic core body and a plug connector connected with each other.

[0013] The assembly system includes an assembly table 8, and the assembly table 8 is a square table body, and the four edges of the assembly table 8 are a shell loading operation station 1, a sealing ring loading operation station 3, a core loading operation station 6 and an idle operation station 4 respectively.In the process of assembling the pressure sensor, one operation worker is always stationed on the shell loading operation station 1, the sealing ring loading operation station 3 and the core loading operation station 6 respectively, that is, one operation worker is always stationed on three edges of the assembly table 8, and no operation worker is always stationed on the idle operation station 4.

[0014] The assembly table 8 is equipped with a conveying mechanism, on which an assembly fixture 10 is mounted. The conveying mechanism can deliver the assembly fixture 10 to each of the four operating stations on the assembly table 8. In one embodiment, the assembly fixture 10 includes a limiting insertion hole, the shape of which is consistent with the bottom shape of the sensor housing 13, allowing the sensor housing to be inserted into the limiting insertion hole. At the housing loading operating station 1, the operator loads the sensor housing 13 onto the assembly fixture 10. At the sealing ring loading operating station 3, the operator loads the sealing ring 12 into the interior of the sensor housing 13. At the core loading operating station 6, the operator mounts the ceramic core assembly 11 onto the pressing mechanism, and then the pressing mechanism presses the ceramic core assembly 11 onto the sensor housing 13 to obtain the finished pressure sensor.

[0015] Because the pressure sensor assembly process involves manual loading, the sealing ring 12 may sometimes be missing. Therefore, a sealing ring detection mechanism and an alarm mechanism are installed at the idle operating station 4, with the two mechanisms electrically connected. After the assembly fixture 10 passes the sealing ring 12 loading station, the conveying mechanism delivers the assembly fixture 10 to the idle operating station 4. The sealing ring detection mechanism then checks the sensor housing 13 on the assembly fixture 10 to see if a sealing ring 12 is present inside. If a missing sealing ring 12 is found inside the sensor housing 13, the alarm mechanism sends an alarm signal, notifying other operators to come to the idle operating station 4 to handle the issue and replace the missing sealing ring 12 inside the sensor housing 13, thus preventing the production of pressure sensor products with missing sealing rings 12.

[0016] As attached Figure 1 As shown, the vacant operating station 4 is adjacent to the sealing ring loading operating station 3 and the core loading operating station 6, while the outer shell loading operating station 1 is opposite to the vacant operating station 4. The conveying mechanism is a rotating disk 9, which can rotate actively. The assembly fixture 10 is installed on the edge of the rotating disk 9. When the assembly fixture 10 rotates with the rotating disk 9, it will cycle through the outer shell loading operating station 1, the sealing ring loading operating station 3, the vacant operating station 4, and the core loading operating station 6. The operator sequentially loads the sensor outer shell 13, the sealing ring 12, and the ceramic core assembly 11 onto the assembly fixture 10. When the assembly fixture 10 passes through the vacant operating station 4, the sealing ring detection mechanism detects whether the sealing ring 12 is missing inside the sensor outer shell 13.

[0017] A secondary inspection station 5 is also provided between the idle operation station 4 and the core loading operation station 6. A sealing ring inspection mechanism is also provided on the secondary inspection station 5. During the process of the assembly fixture 10 rotating from the idle operation station 4 to the core loading operation station 6, the sealing ring inspection mechanism on the secondary inspection station 5 performs a secondary inspection on whether there is a sealing ring 12 inside the sensor housing 13 on the assembly fixture 10, in order to confirm whether the missing sealing ring 12 has been replaced.

[0018] The sealing ring detection mechanism is one or a combination of two of the following: a laser detection probe and a camera. In a preferred embodiment, the sealing ring detection mechanism at the vacant operating station 4 is a laser detection probe, which detects the presence or absence of the sealing ring 12. The sealing ring detection mechanism at the secondary detection station 5 is a camera, which performs a secondary detection of the presence or absence of the sealing ring 12, and can also detect whether the position and model of the sealing ring 12 and the sensor housing 13 are correct.

[0019] Multiple assembly fixtures 10 are arranged circumferentially on the rotating disk 9, which can improve assembly efficiency. The included angle between adjacent assembly fixtures 10 is 45 degrees, and the included angle between the secondary inspection station 5 and the adjacent operation stations on both sides is also 45 degrees. During the rotation of the rotating disk 9, it rotates 45 degrees each time, so that the assembly fixtures 10 can be moved to the secondary inspection station 5 with the rotating disk 9.

[0020] As attached Figure 1 As shown, a housing cleaning station 2 is also provided between the housing loading operation station 1 and the sealing ring loading operation station 3. The housing cleaning station 2 is equipped with a housing cleaning mechanism, which can clean the inside of the sensor housing 13. The housing cleaning station 2 is at a 45-degree angle with the adjacent operation stations on both sides, so that the assembly fixture 10 can be moved to the housing cleaning station 2 with the rotating disk 9.

[0021] After assembly, the finished pressure sensor returns to the housing loading station 1 as the rotating disk 9 rotates. The operator at the housing loading station 1 unloads the finished pressure sensor, and then the new sensor housing 13 is mounted onto the assembly fixture 10. A finished product cleaning station 7 is also provided between the core loading station 6 and the housing loading station 1. The finished product cleaning station 7 is equipped with a finished product cleaning mechanism to clean the finished pressure sensor. The finished product cleaning station 7 is at a 45-degree angle to the adjacent operating stations on both sides, allowing the assembly fixture 10 to move onto the finished product cleaning station 7 along with the rotating disk 9.

[0022] The working mode of the assembly system is as follows: first, the assembly clamp 10 rotates to the shell loading operation station 1 with the rotating disc 9, the operation worker of the station loads the sensor shell 13 on the assembly clamp 10; second, the assembly clamp 10 rotates to the shell cleaning station 2 with the rotating disc 9, the shell cleaning mechanism cleans the sensor shell 13; third, the assembly clamp 10 rotates to the sealing ring loading operation station 3 with the rotating disc 9, the operation worker of the station loads the sealing ring 12 into the sensor shell 13; fourth, the assembly clamp 10 rotates to the idle operation station 4 with the rotating disc 9, the sealing ring detection mechanism detects whether the sealing ring 12 is in the sensor shell 13, if the sealing ring 12 is missing, an alarm signal is sent through the alarm mechanism, and other operation workers are informed to come to the idle operation station 4 to process, and the missing sealing ring 12 is supplemented in the sensor shell 13; fifth, the assembly clamp 10 rotates to the secondary detection station 5 with the rotating disc 9, and the sealing ring 12 is subjected to secondary detection, so as to confirm that the sensor shell has the sealing ring 12; sixth, the assembly clamp 10 rotates to the core loading operation station 6 with the rotating disc 9, the operation worker of the station loads the ceramic core assembly 11 on the pressing mechanism, the pressing mechanism presses the ceramic core assembly 11 on the sensor shell 13, so as to obtain the pressure sensor finished product; seventh, the assembly clamp 10 rotates to the finished product cleaning station 7 with the rotating disc 9, and the finished product cleaning mechanism cleans the pressure sensor finished product; eighth, the assembly clamp 10 rotates back to the shell loading operation station 1 with the rotating disc 9, the operation worker of the station unloads the pressure sensor finished product, and then returns to the first step.

[0023] The above only describes the preferred embodiments of the present application, and it should be pointed out that, for those skilled in the art, without departing from the principles of the present application, some improvements and refinements can be made, and these improvements and refinements should also be considered as the protection scope of the present application.
