[0028] To illustrate the technical solution described in this utility model, specific embodiments are described below, showing only the parts related to the embodiments of this utility model.

[0029] Example:

[0030] like Figure 1-2 As shown, this utility model provides an assembly fixture for a piezoelectric sensing module in a sensor, used to assemble the piezoelectric sensing module in the sensor. The assembly fixture includes a base plate 1 and multiple assembly slots 2 formed on the base plate 1. Each assembly slot 2 includes a first placement part 21, a second placement part 22, and a removal part 23, both of which are connected to the first placement part 21. The shape of the first placement part 21 matches the shape of the piezoelectric layer 4 in the piezoelectric sensing module, and the combined shape of the first placement part 21 and the second placement part 22 matches the shape of the circuit board 3 in the piezoelectric sensing module. The first placement part 21 and the second placement part 22 are used to assemble the circuit board 3 and the piezoelectric layer 4 to form the piezoelectric sensing module. The assembled piezoelectric sensing module is removed outward through the removal part 23. It should be noted that the sensors described in this embodiment are all piezoelectric sensors.

[0031] The assembly fixture described in this embodiment facilitates the assembly of the piezoelectric sensing module in the sensor. Generally, the piezoelectric sensing module includes a circuit board 3 and a piezoelectric layer 4. Electrical connection between the circuit board 3 and the piezoelectric layer 4 is required for the piezoelectric sensing module to be used in subsequent sensor applications. The assembly fixture in this embodiment ensures accurate connection between the piezoelectric layer 4 and the circuit board 3, improving assembly precision and stability, and ensuring the sensitivity of the subsequently manufactured sensor during use.

[0032] like Figure 2 As shown, the assembly fixture includes a base plate 1 and multiple assembly slots 2 formed on the base plate 1. The assembly slots 2 are the most important part of the assembly fixture, as shown... Figure 1 As shown, each assembly slot 2 includes a first placement part 21, a second placement part 22, and a removal part 23. Figure 1 , Figure 3 As shown, the first placement part 21 matches the shape of the piezoelectric layer 4, and the shape of the second placement part 22 combined with the first placement part 21 matches the shape of the circuit board 3. The first placement part 21 is used to limit the piezoelectric layer 4, and the second placement part 22 is used to limit the circuit board 3. The arrangement of the first placement part 21 and the second placement part 22 facilitates the assembly of the piezoelectric layer 4 on the circuit board 3.

[0033] Furthermore, the multiple assembly slots 2 ensure that multiple piezoelectric sensing modules can be processed simultaneously during the assembly process, further improving production efficiency. It should be noted that in this embodiment, the multiple assembly slots 2 are arranged sequentially in the horizontal and vertical directions of the base plate 1. Specifically, the arrangement of the assembly slots 2 not only makes the tooling structure more compact but also optimizes the operation process. In actual operation, the operator can assemble sequentially along the horizontal or vertical direction, reducing the number of movements during assembly and making the assembly action smoother. In this embodiment, the multiple assembly slots 2 enable large-scale, mass assembly of piezoelectric sensing modules. The size and shape of each assembly slot 2 are carefully designed to ensure perfect fit with the piezoelectric sensing module, ensuring assembly consistency and accuracy while improving assembly efficiency and reducing production costs, providing strong support for the large-scale production of piezoelectric sensing modules.

[0034] In addition, the design of the removal part 23 makes it easy to remove the piezoelectric sensing module from the assembly slot 2 after assembly, avoiding damage to the piezoelectric sensing module and improving assembly efficiency.

[0035] The assembly process of the piezoelectric sensing module using the assembly fixture described in this embodiment is as follows: First, as Figure 1 , Figure 3 As shown, the circuit board 3 is placed in the area formed by the first placement part 21 and the second placement part 22; then, soldering is performed on the corresponding area of ​​the circuit board 3 in the first placement part 21, and the positive and negative electrodes of the piezoelectric layer 4 are placed on the soldered areas of the circuit board 3, so that the piezoelectric layer 4 and the circuit board 3 are electrically connected, thus forming a piezoelectric sensing module. It should be explained in detail that the circuit board 3 is provided with a positive main solder joint and a negative main solder joint, and the piezoelectric layer 4 is provided with a positive electrode and a negative electrode. During assembly, the positive and negative electrodes on the piezoelectric layer 4 need to be connected to the positive and negative main solder joints on the circuit board 3.

[0036] It should be noted that because the shape of the first placement part 21 matches that of the piezoelectric layer 4, and the area formed by the second placement part 22 and the first placement part 21 matches the shape of the circuit board 3, the piezoelectric layer 4 can be accurately placed on top of the circuit board 3 and assembled with it. Finally, the assembled piezoelectric sensing module is removed outward through the removal part 23, completing the assembly process. This assembly fixture not only improves assembly efficiency and simplifies the assembly process but also ensures assembly quality, making the assembly of the piezoelectric sensing module more accurate and efficient, and guaranteeing assembly accuracy.

[0037] As an optional implementation method, such as Figure 1 As shown, the depth of the groove in the first placement part 21 is greater than the depth of the groove in the second placement part 22. Specifically, limiting the depth of the grooves in the first placement part 21 and the second placement part 22 ensures stable positioning of the circuit board 3 and the piezoelectric layer 4 during assembly and facilitates the removal of the assembled piezoelectric sensing module. More specifically, the deeper groove in the first placement part 21 can cooperate with the second placement part 22 to provide more stable support for the circuit board 3, preventing the circuit board 3 from moving or shifting during soldering, while also facilitating the placement of the piezoelectric layer 4. Furthermore, the first placement part 21 can also cooperate with the removal part 23 to facilitate the removal of the assembled piezoelectric sensing module without damaging it, thus improving the integrity of the piezoelectric sensing module and enhancing its assembly quality.

[0038] As an optional implementation method, such as Figure 1 As shown, the depth of the groove in the extraction section 23 is greater than or equal to the depth of the groove in the first placement section 21. Specifically, when removing the assembled piezoelectric sensing module, the extraction section 23 provides sufficient support space for the piezoelectric sensing module, preventing it from being squeezed or jammed during removal. Furthermore, limiting the depth of the extraction section to be greater than or equal to the depth of the first placement section 21 allows it to cooperate with the first placement section 21, helping the operator to remove the piezoelectric sensing module more easily, ensuring its complete removal, reducing operational difficulty, saving time, and improving assembly efficiency.

[0039] As an optional implementation, the corners of the second placement portion 22 are all rounded (not shown in the figure). Specifically, the second placement portion 22 and the second placement portion 22 are combined to place the circuit board 3. Rounding the corners of the second placement portion 22 reduces wear on the corners of the circuit board 3, effectively protecting the circuit board 3 and ensuring that the circuit board 3 is not damaged during assembly. It also makes the placement and removal of the circuit board 3 within the first placement portion 21 and the second placement portion 22 smoother.

[0040] As an optional implementation method, such as Figure 1-2 As shown, the second placement part 22 and the removal part 23 are connected to the edge of the first placement part 21. Specifically, the second placement part 22 and the removal part 23 are both located on the periphery of the first placement part 21 and are connected to it. Therefore, the first placement part 21, the second placement part 22, and the removal part 23 form a connected groove. This arrangement facilitates the placement of the circuit board 3 within the first placement part 21 and the second placement part 22, and also facilitates the operator in removing the assembled piezoelectric sensing module from the first placement part 21. Furthermore, the piezoelectric sensing module can be more easily aligned with the assembly slot 2, further improving the accuracy and efficiency of the assembly.

[0041] As an optional implementation, the base plate 1 is made of plastic. Using plastic as the base plate 1 is advantageous because plastic is lightweight, facilitating the carrying and movement of the entire assembly fixture. Furthermore, the plastic base plate 1 has good corrosion resistance, adapting to various working environments and extending the service life of the fixture. Simultaneously, plastic is easy to process and mold, allowing the base plate 1 to be designed to meet actual assembly requirements in terms of shape and structure. More specifically, the base plate can be made of phenolic resin.

[0042] The assembly fixture described in this embodiment can ensure the accuracy and stability of the piezoelectric sensing module in the sensor during the assembly process, and can improve assembly efficiency and assembly quality.

[0043] The embodiment is merely a special case and does not indicate that this utility model is implemented in such a way.

[0044] The above description is merely a preferred embodiment of the present utility model. Those skilled in the art will understand that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of the present utility model. Furthermore, under the teachings of the present utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of the present utility model. Therefore, the present utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of the present utility model.
