[0025] Example

[0026] Reference Figure 1-4 This is an embodiment of the present invention, which provides a speaker diaphragm assembly fixture, comprising:

[0027] The support assembly 100 includes a base plate 101, a support seat 102 fixedly connected to the end of the base plate 101, a support plate 103 fixedly connected to the side wall of the support seat 102, and an adapter plate 104 bolted to the side wall of the support plate 103.

[0028] Assembly component 200 includes a connector 201 slidably connected to the side wall of adapter plate 104, a connecting rod 202 inserted into the side wall of connector 201, a pressing cylinder 203 fixedly connected to the end side wall of connecting rod 202, and a pressing head 204 adapted to be installed at the end of the output shaft of pressing cylinder 203. A pad 205 is bolted to the side wall of support plate 103, and a positioning seat 206 is fixedly connected to the side wall of pad 205. The end of pressing head 204 extends above positioning seat 206.

[0029] The support assembly 100 serves as the basic load-bearing structure of the entire fixture, consisting of multiple components working together to form a stable framework. The base plate 101, acting as the bottom support, provides a stable mounting surface for the entire fixture, ensuring its stability during operation. The support base 102, fixedly connected to the end of the base plate 101, acts like a column in a building, playing a crucial role in upward support. The support plate 103, fixedly connected to the side wall of the support base 102, is horizontal, providing a horizontal support platform for the installation of subsequent components. The adapter plate 104, bolted to the side wall of the support plate 103, not only achieves a detachable connection with the support plate 103 for easy maintenance and replacement but also provides a connecting carrier for the installation of the assembly assembly 200, a core component for realizing the key functions of the speaker diaphragm assembly. The connector 201, slidably mounted on the side wall of the adapter plate 104, allows for linear sliding on the adapter plate 104, providing a flexible basis for the movement of subsequent components. The connecting rod 202 is inserted into the side wall of the connector 201, forming a stable connection with the connector 201. It also connects and supports components such as the pressing cylinder 203 and the unloading cylinder 207. The pressing cylinder 203 is fixedly connected to the end side wall of the connecting rod 202. A pressure head 204 is fitted to the end of its output shaft, allowing it to move up and down under the drive of the pressing cylinder 203, thus pressing the speaker diaphragm. The pad 205 is bolted to the side wall of the support plate 103, providing an mounting surface for components such as the positioning seat 206. The positioning seat 206 is fixedly connected to the side wall of the pad 205. The ends of the pressure head 204 and the unloading rod 208 both extend above the positioning seat 206. The positioning seat 206 precisely positions the speaker diaphragm, ensuring the accuracy of the pressing and unloading operations.

[0030] Specifically, the assembly assembly 200 also includes a stripping cylinder 207 fixedly connected to the center of the end of the connecting rod 202, and a release rod 208 adapted to be installed at the end of the output shaft of the stripping cylinder 207. The end of the release rod 208 is inserted into the middle of the slot on the side wall of the pressure head 204, and the end of the release rod 208 extends to the upper side wall of the positioning seat 206.

[0031] The unloading cylinder 207 is fixedly connected to the center of the end of the connecting rod 202, and the unloading rod 208 at the end of its output shaft is inserted into the slot in the middle of the side wall of the pressure head 204, with the end of the unloading rod 208 extending to the upper side wall of the positioning seat 206. This structural design allows the unloading cylinder 207 to drive the unloading rod 208 after the pressing operation is completed, thereby detaching the pressed diaphragm from the pressure head 204 and realizing an automated unloading process.

[0032] Furthermore, a sensor mounting bracket 209 is bolted to the side wall of the pad 205. The end of the sensor mounting bracket 209 extends to the outside of the positioning seat 206, and the positioning seat 206 is symmetrically mounted on the side wall of the pad 205.

[0033] The sidewall of the pad 205 is also bolted with a sensor mounting bracket 209, the end of which extends to the outside of the positioning seat 206 for mounting sensors to monitor various parameters during the assembly process. Meanwhile, the positioning seats 206 are symmetrically mounted on the sidewall of the pad 205, ensuring uniform stress and stability of the diaphragm during assembly.

[0034] Furthermore, the support assembly 100 also includes an adjusting rod 105 fixedly connected to the side wall of the connecting rod 202, and a guide plate 106 fixedly connected to the side wall of the adapter plate 104. The side wall of the guide plate 106 is provided with a groove that cooperates with the end of the adjusting rod 105, and the end of the adjusting rod 105 is inserted into the inside of the groove on the side wall of the guide plate 106.

[0035] The support assembly 100 also includes an adjusting rod 105 and a guide plate 106. The adjusting rod 105 is fixedly connected to the side wall of the connecting rod 202 and can move with the movement of the connecting rod 202. The guide plate 106 is fixed to the side wall of the adapter plate 104, and the groove on its side wall precisely matches the end of the adjusting rod 105, similar to the relationship between a track and a slider, providing guidance for the movement of the adjusting rod 105, thereby ensuring the stability and accuracy of the connecting rod 202 during movement.

[0036] Preferably, a main shaft 107 is rotatably mounted at the center of the adapter plate 104. The end of the main shaft 107 extends through and to the side wall of the guide plate 106. A lever 108 is fixedly connected to the end of the main shaft 107. The lever 108 is inserted between the guide plate 106 and the connecting rod 202. The end of the lever 108 is provided with a limiting groove for use with the adjusting rod 105. The end of the adjusting rod 105 is inserted into the inner side of the limiting groove at the end of the lever 108.

[0037] The main shaft 107, rotatably mounted at the center of the adapter plate 104, extends through and to the side wall of the guide plate 106. A lever 108 fixed at the end of the main shaft 107 is cleverly inserted between the guide plate 106 and the connecting rod 202, and a limiting groove at its end cooperates with the adjusting rod 105. This structural design allows the rotation of the main shaft 107 to drive the adjusting rod 105 via the lever 108, thereby achieving position adjustment of the connecting rod 202.

[0038] It should be noted that a motor 109 is fixedly connected to the side wall of the support plate 103, and the output shaft end of the motor 109 is connected to the main shaft 107 via a coupling.

[0039] Among them, the motor 109, which is fixed to the side wall of the support plate 103, has its output shaft connected to the main shaft 107 through a coupling, providing a power source for the entire adjustment process and realizing the automated position adjustment function.

[0040] Preferably, a limiting block 110 is fixedly connected to the end side wall of the adapter plate 104, and a side strip is installed on the end side wall of the connecting rod 202 to cooperate with the middle groove of the limiting block 110, and the limiting block 110 cooperates with the positioning seat 206.

[0041] The limiting block 110 on the end sidewall of the adapter plate 104 cooperates with the edge strip installed on the end sidewall of the connecting rod 202. The edge strip can be precisely embedded in the groove in the middle of the limiting block 110, thereby limiting the movement range of the connecting rod 202. Furthermore, the limiting block 110 works in conjunction with the positioning seat 206 to further ensure the positional accuracy during assembly.

[0042] In use, when assembling the horn diaphragm, the horn diaphragm is first placed on the positioning seat 206, which precisely positions the diaphragm. Then, the motor 109 starts, driving the main shaft 107 to rotate via the coupling. The lever 108 at the end of the main shaft 107 rotates accordingly. Through its interaction with the adjusting rod 105, the lever 108 drives the connecting rod 202 to slide along the groove of the guide plate 106 on the adapter plate 104, thereby moving the pressure head 204 and the release rod 208 to the appropriate working position.

[0043] Next, the pressing cylinder 203 is activated, and its output shaft drives the pressing head 204 downward to press the speaker diaphragm placed on the positioning seat 206. After pressing is completed, the pressing cylinder 203 drives the pressing head 204 upward to reset. At this time, the unloading cylinder 207 is activated, and its output shaft pushes the release rod 208 upward. The release rod 208 removes the pressed diaphragm from the pressing head 204, completing the entire assembly process. During this process, the sensors on the sensor mounting bracket 209 monitor various parameters in real time during the assembly process to ensure the accuracy and stability of the assembly work.

[0044] In summary, precise positioning of the speaker diaphragm via the positioning seat 206, along with the coordination of the adjusting rod 105 with the guide plate 106 and the lever 108, enables accurate adjustment of the positions of the pressure head 204 and the release lever 208. This ensures the accuracy of the diaphragm pressing and unloading processes, effectively improving the assembly precision of the speaker diaphragm. The driving of the pressing cylinder 203 and the unloading cylinder 207 reduces manual operation, significantly improving the efficiency of the speaker diaphragm assembly. Simultaneously, the automated position adjustment function driven by the motor 109 further enhances overall efficiency. The detachable connection allows for quick and convenient maintenance and replacement when the fixture malfunctions or parts need to be replaced, reducing maintenance and time costs.
