Description

Technical Field

[0001] The utility model relates to the technical field of tooling fixtures, in particular to a tooling fixture for detecting surface acoustic wave filter devices. Background Art

[0002] A surface acoustic wave filter is a filter realized by using the piezoelectric characteristics of piezoelectric materials. It mainly uses input and output transducers to convert the input signal of the radio wave into mechanical energy. After processing, the mechanical energy is converted back into an electrical signal to filter out unnecessary signals and noise and improve the reception quality. Surface acoustic wave filters are widely used in various wireless communication systems, televisions, video recorders, and global positioning system receivers to replace LC resonant circuits and achieve inter-stage coupling and filtering.

[0003] Currently, tooling fixtures are required in the detection process of surface acoustic wave filter devices.

[0004] A detection jig for a filter disclosed in the prior art with the publication number CN219039244U includes a box body. A support frame is connected to the upper end of the box body. A break plate is connected to the middle of the support frame. Two sliding rods are connected to the lower end of the break plate. A glass plate is arranged at the lower end of the break plate.

[0005] This detection jig can perform contact detection on the wire heads of the filter to achieve the purpose of complete detection.

[0006] When actually detecting the wire heads of the surface acoustic wave filter, the pins need to be inserted into the corresponding detection slots, and then auxiliary detection is performed through the detection head. This detection method has great defects in actual application. Since it is a fully manual operation, the efficiency is low. And when loading, it is necessary to first take out the surface acoustic wave filter that has been detected, then place the surface acoustic wave filter to be detected, and finally start the detection. The above operations are repeated in this detection process. Since the taking and placing process takes a long time and cannot be compressed within the detection time, it undoubtedly further reduces the detection efficiency. Therefore, improvements are proposed. Summary of the Utility Model

[0007] The utility model is proposed to solve the shortcomings existing in the prior art, and provides a tooling fixture for detecting surface acoustic wave filter devices.

[0008] To achieve the above purpose, the utility model adopts the following technical scheme: A tooling fixture for detecting surface acoustic wave filter devices includes a base. A support is fixedly installed on one side of the top of the base. A pressing component is installed on the support.

[0009] A detection table is fixedly installed on one side of the top of the base.

[0010] One side of the top of the base is fixedly installed with a housing, the top of the housing is rotatably connected with a movable frame, and a rotating assembly is jointly installed between the movable frame and the housing;

[0012] Furthermore, the pressing assembly includes a cylinder, and the cylinder is fixedly installed on the top of the bracket. The movable end of the cylinder penetrates through the bracket and is fixedly connected with a pressing seat, and the pressing seat is matched with the surface acoustic wave filter body. The setting of the cylinder is beneficial to push the pressing seat to rise or fall.

[0013] Furthermore, one side of the top of the pressing seat is fixedly installed with a sliding rod, and the sliding rod penetrates through the bracket and is slidably connected with it. The cooperation between the sliding rod and the bracket has a limiting function, which can ensure the stability of the movement of the pressing seat.

[0014] Furthermore, the rotating assembly includes a motor, and the motor is fixedly installed on the inner wall of one side of the housing. The driving end of the motor is fixedly connected with a driving gear. One side of the outer surface of the driving gear is meshed with a driven gear, and the mounting shaft of the driven gear penetrates through the housing and is fixedly connected with the movable frame, which can drive the movable frame to rotate. The movable frame can switch the positions of the two positioning toolings through the elastic movable parts.

[0015] Furthermore, each of the four elastic movable parts includes a guide rod, and the guide rod is fixedly installed inside the movable frame. A slider is slidably sleeved on the outer surface of the guide rod. A spring is jointly and fixedly connected between the bottom of the slider and the inner bottom of the movable frame, and the spring is sleeved on the outer surface of the guide rod.

[0017] Furthermore, the surface acoustic wave filter body is matched with the detection table, which is convenient for detecting the pins of the surface acoustic wave filter body.

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

[0019] When the utility model is in use, for a fixture for detecting a surface acoustic wave filter device, through the arranged bracket, pressing component, housing, movable frame, rotating component, elastic movable piece and positioning tooling, the whole adopts semi-automatic detection. When the surface acoustic wave filter body is located below the pressing component, the pressing component cooperates with the positioning tooling to clamp the surface acoustic wave filter body, and then it is pushed down for detection, reducing manual participation and improving the detection efficiency. At the same time, the whole adopts a double-station design, compressing the time required for loading and unloading within the detection time, which can further improve the detection efficiency.

[0028] On one side of the top of the base 1, a housing 17 is fixedly installed. The top of the housing 17 is rotatably connected with a movable frame 4. The housing 17 has a supporting effect on the movable frame 4, which is beneficial to the installation of the movable frame 4. A rotating component is jointly installed between the movable frame 4 and the housing 17. The rotating component includes a motor 16, and the motor 16 is fixedly installed on one side inner wall of the housing 17. The driving end of the motor 16 is fixedly connected with a driving gear 15. On one side of the outer surface of the driving gear 15, a driven gear 14 is meshed and connected. The mounting shaft of the driven gear 14 penetrates through the housing 17 and is fixedly connected with the movable frame 4. The motor 16 drives the driving gear 15 to rotate, and the driving gear 15 can drive the movable frame 4 to rotate through the driven gear 14.

[0029] Four elastic movable parts are symmetrically and fixedly installed inside the movable frame 4. A positioning tooling is jointly fixedly installed between two elastic movable parts on the same side. The surface acoustic wave filter body 3 is placed on both positioning toolings. The four elastic movable parts all include guide rods 11, and the guide rods 11 are fixedly installed inside the movable frame 4. A slider 12 is slidably sleeved on the outer surface of the guide rod 11. A spring 13 is jointly fixedly connected between the bottom of the slider 12 and the inner bottom of the movable frame 4, and the spring 13 is sleeved on the outer surface of the guide rod 11. The spring 13 can assist in pushing the slider 12 to move back to its original position.
