[0001] This invention relates to the field of loudspeaker technology, specifically to loudspeaker housing and component mounting equipment and visual inspection equipment. Background Technology

[0002] In the field of loudspeaker manufacturing, the precise installation of the housing and components is a core process to ensure the sound quality, structural stability, and lifespan of the loudspeaker. The installation accuracy and fixing reliability directly determine the final product quality of the loudspeaker. Loudspeaker components need to be precisely aligned with the mounting carrier before being fastened to the housing. The entire process requires multiple steps, including positioning, limiting, fixing, and testing, which places high demands on ease of operation, positioning accuracy, and timeliness of testing.

[0003] The existing equipment lacks a coordinated layered limiting and fixing structure with trapezoidal blocks, curved panels, triangular grooves, annular surfaces, embedded rods, and threaded sleeves. It only adopts a single fixing method and has no initial limiting design. During the docking process, the components are prone to loosening and displacement. The subsequent fixing structure is not strong enough and cannot achieve precise spiral fixing. After the components are installed, they are prone to falling off or shifting. Long-term use can easily lead to speaker sound distortion and frequent failures, which cannot meet the long-term operation requirements of the speaker. Summary of the Invention

[0036] The present invention will now be further described with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. It should be understood that the described embodiments are merely some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0037] Please see Figures 1 to 16 The present invention provides a technical solution: Example 1, such as Figure 1 , Figure 2 and Figure 3 As shown, the outer shell 1 and the square plate 2 serve as the basic mounting carriers for the equipment. Both have corresponding threaded holes on their outer sides. The screw 9 is threaded into the threaded holes. Tightening the screw 9 securely fixes the outer shell 1 and the square plate 2, ensuring that there is no looseness after installation. The component 3 is located at the center of the square plate 2 and is the core working component of the speaker. A notch 8 is opened on its back for initial positioning by cooperating with the corresponding structure on the square plate 2. The mating part 4 is located on the outer side of the square plate 2 near the top and is adapted to connect with both the square plate 2 and the component 3. It is used to achieve precise installation and fixation between the square plate 2 and the component 3, ensuring the stability of the component 3 after installation.

[0038] The outer side of the square plate 2 is fixedly connected with a locking piece 6 and a fitting block 7 by welding. The two work together to achieve the initial positioning and lateral limiting of the component 3. The locking pieces 6 are symmetrically distributed, and their inner sides slide and adapt to the outer side of the component 3. When the component 3 moves towards the square plate 2, the locking pieces 6 can laterally limit the component 3 to prevent the component 3 from shifting up, down, left, or right. The fitting block 7 fits into the first notch 8 opened on the back of the component 3. When the component 3 moves to the preset position, the fitting block 7 is inserted into the first notch 8 to achieve the initial positioning of the component 3 and the square plate 2, ensuring that the subsequent docking part 4 can be accurately docked.

[0039] Example 2, as follows Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 and Figure 14 As shown, the trapezoidal block 41 is fixedly installed on the outer side of the square plate 2 near the top. The bottom slope is fixedly connected to the curved panel 418 by welding. The curved panel 418 is used to adapt to the corresponding structure on the back of the component 3 to achieve guidance and limiting. The trapezoidal block 41 has a cylindrical groove inside, and a slider 42 is slidably adapted in the cylindrical groove. The slider 42 can slide up and down along the cylindrical groove to provide installation and sliding support for the sleeve 43. The center of the slider 42 is fixedly connected to the sleeve 43 by welding. The sleeve 43 passes through the top and bottom of the trapezoidal block 41 and the curved panel 418 respectively and extends to the outside. It can slide up and down synchronously with the slider 42 and can rotate around its own axis.

[0040] A block is rotatably mounted on the bottom of the sleeve 43 via a bearing. A conical spring 44 is fixedly connected to the bottom of the block by welding. The conical spring 44 has good elastic restoring ability. An insert rod 45 is fixedly connected to the end away from the bearing by welding. The insert rod 45 is slidably adapted to the inside of the sleeve 43 and can slide up and down along the sleeve 43. At the same time, it can rotate around the axis of the sleeve 43 with the block. The insert plate 46 is fixedly installed on the outer side of the square plate 2 near the top, above the trapezoidal block 41. It has slots on both sides for sliding adaptation with the fixed rail 411 inside the component 3. An elastic sealing strip 415 is fixedly connected to the outer side of the insert plate 46 by adhesive bonding to enhance the sealing performance between the insert plate 46 and the component 3 and prevent dust from entering the connection.

[0041] A ring rail assembly 47 is bolted to the top of the insert plate 46. The ring rail assembly 47 consists of a ring rail and a slip ring. The ring rail is fixed to the top of the insert plate 46, and the slip ring is slidably connected to the ring rail and can rotate flexibly around the ring rail. A knob 48 is welded to the top of the slip ring for manual adjustment by the operator. A threaded sleeve 49 is welded to the center of the top of the knob 48. The center of the threaded sleeve 49 is threaded to the insert rod 45. By rotating the knob 48, the insert rod 45 can be driven to move up and down along the sleeve 43.

[0042] The sleeve 43 extends from the bottom to the top of the sliding plate 46. An outer plate 40 is fixedly connected to the top of the sleeve 43 by welding. The outer plate 40 is used to drive the sleeve 43 to rotate. A top ring 401 and a protective head 404 are fixedly connected to the top and bottom of the outer plate 40 by welding, respectively. The protective head 404 is used to protect the circular groove 406 to prevent dust and damage. A handle 403 is fixedly connected to both sides of the top ring 401 by welding. The operator can rotate the outer plate 40, thereby driving the sleeve 43 to rotate. A semi-circular groove 402 is provided on the outer side of the knob 48. The inner wall of the semi-circular groove 402 is slidably adapted to the handle 403 to ensure that the handle 403 can rotate flexibly. At the same time, it limits the handle 403 to prevent it from deviating during rotation.

[0043] The top of the insert plate 46 has a semi-circular channel 405, which is distributed along the semi-circle of the top of the insert plate 46. Both ends of the channel 405 have circular grooves 406 for fitting with the hemispherical column 408. The bottom of the outer plate 40 away from the protective head 404 is fixedly connected to the sleeve column 407 by welding. The bottom of the sleeve column 407 has a groove, and the hemispherical column 408 is slidably fitted in the groove. The hemispherical column 408 can slide up and down along the groove. The bottom of the hemispherical column 408 fits into the circular groove 406 to achieve positioning and locking of the outer plate 40, ensuring that the sleeve 43 can be stably fixed after rotation. The outside of the hemispherical column 408 is fixedly connected to the spring 409 by welding. The end of the spring 409 away from the hemispherical column 408 is fixedly connected to the bottom of the sleeve column 407 to provide elastic restoring force for the hemispherical column 408, ensuring that the hemispherical column 408 can flexibly insert into and disengage from the circular groove 406.

[0044] Near the top of the back of component 3, a square groove 400 and a triangular groove 412 are respectively provided. The square groove 400 and the triangular groove 412 are connected to each other to provide space for the insertion of the docking part 4. The two sides inside the square groove 400 are fixedly connected by welding to the fixed rails 411. The fixed rails 411 are slidably adapted to the grooves on both sides of the inserting slide plate 46 to guide the inserting slide plate 46 to be accurately inserted into the square groove 400, and at the same time to achieve lateral fixation of the inserting slide plate 46 and component 3 to prevent left and right displacement. A semi-circular groove 417 is provided inside the square groove 400. The semi-circular groove 417 is slidably adapted to the trapezoidal block 41 for the rotation and limiting of the trapezoidal block 41.

[0045] The interior of the triangular groove 412 fits into the trapezoidal block 41, achieving initial positioning of the trapezoidal block 41 and the component 3. An annular surface 416 is provided on the side of the triangular groove 412 near the semi-annular groove 417. The annular surface 416 slides into the curved panel 418, guiding its sliding and rotation. A vertical groove 413, connected to the triangular groove 412, is provided on the back of the component 3. The vertical groove 413 slides into the sleeve 43, providing space for its movement. An adapter hole 414 is provided at the bottom of the annular surface 416. The adapter hole 414 slides into the insert rod 45. By inserting the insert rod 45 into the adapter hole 414, longitudinal locking of the mating part 4 and the component 3 is achieved, ensuring a secure installation.

[0046] Example 3, as follows Figure 15 and Figure 16 As shown, the visual inspection equipment is used to detect the perpendicularity of the end of the screw 9 to ensure the installation accuracy of the housing 1 and the square plate 2. It mainly includes a detection unit 5, which is located inside the housing 1 and is fixedly connected to both the square plate 2 and the housing 1. The core components include a support seat 51, a fixed shaft 52, a detection plate 53, a fixed panel 54, an outer connecting block 55, a pointer 56, an elastic telescopic rod 57, and a visual sensor 58.

[0047] The support seat 51 is fixedly connected to the back of the square plate 2 by bolts, providing installation support for the fixed shaft 52; the fixed shaft 52 is fixedly connected to the inside of the support seat 51 by welding, and the detection plate 53 is rotatably installed on the outside of the fixed shaft 52 by bearings. The detection plate 53 can flexibly deflect around the fixed shaft 52; the top and bottom of the detection plate 53 are respectively fitted with the ends of the two screws 9. The perpendicularity of the ends of the screws 9 is judged by the fitting state of the detection plate 53. If the ends of the screws 9 are not perpendicular, the detection plate 53 will be pushed to deflect.

[0048] A fixed panel 54 is fixedly connected to the outer side of the fixed shaft 52 by welding. The fixed panel 54 is symmetrically arranged on both sides of the detection plate 53 and is used to install the pointer 56 and provide a sliding trajectory. An arc-shaped groove is opened on the outer side of the fixed panel 54, and the pointer 56 is slidably adapted in the arc-shaped groove. The pointer 56 can slide along the arc-shaped groove. An outer connecting block 55 is fixedly connected to the outer side of the pointer 56 by welding. The end of the outer connecting block 55 away from the pointer 56 is fixedly connected to the detection plate 53 and is used to convert the deflection angle of the detection plate 53 into the displacement of the pointer 56, which is convenient for the vision sensor 58 to detect.

[0049] An elastic telescopic rod 57 is bolted to the back of the square plate 2. The end of the elastic telescopic rod 57 away from the square plate 2 is fixedly connected to the detection plate 53 to provide elastic restoring force for the detection plate 53, ensuring that the detection plate 53 can return to its initial fitting state after the detection is completed or the screw 9 is adjusted to the correct position. Visual sensors 58 are bolted to the top and bottom of the inner cavity of the outer shell 1. The visual sensor 58 consists of a visual sensor and an alarm. The visual sensor is used to visually collect the displacement signal of the pointer 56 and the installation accuracy of the screw 9. The alarm is used to trigger an alarm when the detection is unqualified, prompting the operator to make timely adjustments.

[0050] The working principle of the present invention is as follows: First, hold the component 3 and move it toward the square plate 2. Then, the outer side of the component 3 slides and adapts to the locking piece 6, while the first notch 8 fits and adapts to the interlocking block 7, so as to achieve the initial positioning of the component 3 and the square plate 2.

[0051] During the docking process between component 3 and square plate 2, the sliding plate 46 fixed on square plate 2 will slide and adapt to the fixed rail 411 inside square groove 400. At the same time, the curved plate 418 connected to the inclined part of trapezoidal block 41 will squeeze and adapt to the part of component 3 near triangular groove 412, causing trapezoidal block 41 and curved plate 418 to move upward relative to slider 42, while sleeve 43 slides and adapts to vertical groove 413. Finally, curved plate 418 fits into the annular surface 416 of the left half of triangular groove 412. At the same time, the bottom of trapezoidal block 41 is in a suspended state, and the part of its bottom extending upward a certain distance fits into the part where triangular groove 412 and vertical groove 413 are slotted together, so that trapezoidal block 41 cannot be reset and moved, thereby achieving the initial positioning of component 3 and square plate 2.

[0052] By rotating the knob 48 clockwise, the threaded sleeve 49 connected to its center drives the insert rod 45 to move downward. Then, the insert rod 45 moves downward along the sleeve 43 and stretches the conical spring 44 until it fits into the adapter hole 414, thereby achieving the limiting and fixing of the component 3 and the square plate 2.

[0053] When it is necessary to separate the square plate 2 and component 3, turn the knob 48 counterclockwise, causing the insert rod 45 to return to its original position and move upward, disengaging from the adapter hole 414. Then, the operator turns the handle 403 clockwise along the semicircular groove 402, causing the outer connecting plate 40, connected to it via the top ring 401, to drive the sleeve 43 to rotate clockwise synchronously. Immediately before the handle 403 is turned, the semicircular column 408, under the elastic force of the spring 409, engages with the left circular groove 406. However, as the handle 403... The clockwise rotation of 03 causes the sleeve 407 fixed at the bottom of the outer plate 40 to drive the hemispherical column 408 to rotate clockwise along the hemispherical channel 405. Because the depth of the circular groove 406 is greater than that of the hemispherical channel 405, when the hemispherical column 408 moves onto the hemispherical channel 405, it will compress the spring 409 until the hemispherical column 408 moves to the right circular groove 406 and the spring 409 returns to its original position, thereby achieving the function of fixed-point circumferential rotation of the handle 403, the outer plate 40 and the sleeve 43.

[0054] As the sleeve 43 rotates 180° clockwise, and under the limiting action of the slider 42, the curved panel 418 rotates 180° clockwise along the annular surface 416. At the same time, the trapezoidal block 41 slides into the semi-annular groove 417 near the front protrusion of the curved panel 418. Finally, the trapezoidal block 41 rotates 180° clockwise with its bottom as the center, so that the curved panel 418 faces the right half of the triangular groove 412. Therefore, when the operator separates the square plate 2 from the component 3, the curved panel 418 and the right half of the triangular groove 412 are pressed together and the trapezoidal block 41 is driven to return to its original position until the docking part 4 is disengaged from the component 3, thereby achieving rapid separation of the two.

[0055] After the square plate 2 and component 3 are fastened, the outer shell 1 and the square plate 2 are fastened together using the screw 9. If the lower screw 9 is not aligned with the bolt on the same vertical plane, that is, if the end of the lower screw 9 protrudes forward by a section, it will squeeze the lower half of the detection plate 53, causing the detection plate 53 to deflect clockwise around the fixed shaft 52. At the same time, the outer connecting blocks 55 fixed on both sides of the detection plate 53 will drive the pointer 56 to deflect clockwise around the groove on the fixed panel 54. At this time, the visual sensor inside the visual sensor 58 located at the top of the inner cavity of the outer shell 1 will receive the image and signal, and then transmit the signal to the control terminal inside the alarm. The control terminal then receives, judges and releases the signal, thereby activating the alarm to remind the operator that the screw 9 has been mis-tightened.

[0056] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any modifications made by those skilled in the art based on the above concepts without creative effort shall fall within the scope of protection of the present invention.
