The conveying component 200 is responsible for the continuous transfer of the bottom shell 900, the pose acquisition component 500 acquires the pose information of the bottom shell 900 and the speaker 800 in real time and guides the assembly component 600 to perform precise pressing, and the quality inspection component 700 inspects the assembly results and automatically sorts out defective products. The various processes are smoothly connected and work together without human intervention, thus effectively solving the problems of high labor costs, low production efficiency, inconsistent installation standards, and inconsistent product quality in existing related technologies. While significantly improving production efficiency, it also ensures the consistency and stability of product assembly quality.

[0040] Specifically, in this embodiment, the rack 100 includes a base plate 110 at the top, and the conveying assembly 200 is disposed on the outer side of the base plate 110, in conjunction with reference to... Figure 5 , Figure 5 This is a schematic diagram of the conveying component in an embodiment of this application. The predetermined conveying direction of the conveying component 200 is shown by the line segment with arrows in Figure 5. Specifically, the conveying component 200 in this embodiment can be a production line 210 constructed using belt conveyors commonly used in the art. Furthermore, the production line 210 can be configured to include two sets of belt conveyor units spaced apart, and the spacing between the two sets of belt conveyor units can be adjusted according to different parameters such as the width of the fixture 420 to suit different production requirements.

[0041] Specifically, the bottom shell supply assembly 400 in this embodiment includes a jig 420 and an intercepting and positioning member 430. The jig 420 is disposed on the conveying assembly 200 and is used to carry and convey multiple bottom shells 900. (Refer to...) Figure 6 , Figure 6 This is a schematic diagram of the fixture in this embodiment. The fixture 420 in this embodiment is rectangular, and has multiple material troughs 421, each adapted to a bottom shell 900, spaced apart along its length. During operation, multiple bottom shells 900 are placed in the multiple material troughs 421 on the fixture 420. The fixture 420 is placed on the conveying assembly 200, with its length direction aligned with the conveying direction of the conveying assembly 200. When the conveying assembly 200 operates, it moves the fixture 420 forward, thereby carrying and transporting multiple bottom shells 900.

[0042] The intercepting and positioning component 430 is mounted on the frame 100 and is used to intercept and position the fixture 420 at a predetermined assembly station according to the production cycle. This facilitates the pose acquisition component 500 in acquiring the pose information of the base shell 900, and also facilitates the assembly component 600 in assembling the speaker 800 into a predetermined position within the base shell 900. For details, please refer again... Figure 4 Combined with reference Figure 7 , Figure 7 This is a schematic diagram of the interception and positioning component in this embodiment. The interception and positioning component 430 in this embodiment includes a first guide rod 431, a first slide block 432, a positioning card 433, a top rod 434, a first power component 435, and a second power component 436. The first guide rod 431 is disposed on the base plate 110 of the frame 100 along the conveying direction of the conveying assembly 200, and is located below the conveying assembly 200. The first slide block 432 is slidably connected to the first guide rod 431 and can slide along the conveying direction of the conveying assembly 200 on the first guide rod 431. The positioning card 433 is fixed to the first slide block 432 and extends into the conveying path of the conveying assembly 200 to intercept the fixture 420. Specifically, the top of the positioning card 433 extends to the top of the conveying assembly 200 and is a certain distance above the fixture 420 on the conveying assembly 200. The top of the positioning card 433 can be approximately set as... Figure 7The U-shaped block shown has a top shape of positioning card 433 that matches the size of fixture 420. The top material rod 434 is vertically mounted on the first slide block 432, and its position corresponds to the position of positioning card 433. Specifically, the top of the top material rod 434 can be configured as a long rod that matches the length of fixture 420. The extension direction of the top of the top material rod 434 is consistent with the conveying direction of conveying assembly 200. The top of the top material rod 434 is located in the gap between the two parts of conveying assembly 200 and can pass through the gap to... The fixture 420 is lifted; the first power component 435 is mounted on the frame 100 and drives the first slide 432 to move along the conveying direction of the conveying assembly 200; the second power component 436 is mounted on the first slide 432 and drives the top rod 434 to move vertically to lift the fixture 420, and, together with the positioning card 433, positions the fixture 420, thereby facilitating the pose acquisition assembly 500 to acquire the pose information of the bottom shell 900, and facilitating the assembly assembly 600 to assemble the speaker 800 into the predetermined position inside the bottom shell on the fixture 420. The first power component 435 and the second power component 436 can both be telescopic cylinders commonly used in the art, or can be implemented using lead screw mechanisms commonly used in the art, as long as the corresponding driving function can be achieved. The specific structure of the first power component 435 or the second power component 436 is not limited here.

[0043] For details, please refer to again. Figure 4 Combined with reference Figure 8 and Figure 9 , Figure 8 This is a schematic diagram of the speaker supply assembly in an embodiment of this application. Figure 9 This is a schematic diagram of the material tray in the embodiment of this application. The horn supply assembly 300 is disposed on the frame 100 and located on one side of the conveying assembly 200, and includes a frame 301, a base 310, a locking buckle 311, a feeding stacking rod 312, a receiving stacking rod 313, a material tray 320, and a conveying unit 330.

[0044] The frame 301 is mounted on the machine frame 100, and the feeding stacking rod 312, the receiving stacking rod 313, the locking buckle 311, and the base support 310 are all mounted on the frame 301. The material tray 320 is used to hold multiple horns 800. The side of the material tray 320 has a latch 321, which cooperates with the locking buckle 311 to lock and release the material tray 320. The feeding stacking rod 312 is distributed at the four corners of the material tray 320 in the feeding area G1. By constraining the four corners of the material tray 320, it guides the multiple material trays 320 containing horns to be neatly stacked vertically in the feeding area G1. The receiving stacking rod 313 is distributed at the four corners of the material tray 320 in the receiving area G3. It guides the empty material trays 320 that have been loaded to be stacked layer by layer vertically in the receiving area G3.

[0045] Locking buckles 311 are installed on the frame 301, corresponding to the feeding stacking rod 312 and the receiving stacking rod 313 respectively, and are used to releasably lock the bottom tray 320 of the corresponding area. Specifically, the locking buckles 311 are engaged in the slots 321 on the side of the tray 320, locking and suspending the bottom tray 320, so that the entire stack of trays 320 remains stable; when the base support 310 is moved to the corresponding area, the locking buckles 311 release the bottom tray 320, and the tray 320 falls onto the base support 310 and is received by the base support 310.

[0046] The base 310 is movably mounted on the frame 301 to support the material tray 320 and to reciprocate it between workstations under the drive of the conveying unit 330. The conveying unit 330 is connected to the base 310 and drives the base 310 to reciprocate the material tray 320 between the feeding area G1, the picking position G2, and the receiving area G3. The conveying unit 330 can be implemented using a belt conveyor structure commonly used in the art.

[0047] Specifically, the working process of the speaker supply component 300 in this embodiment is roughly as follows: In the initial state, the multiple full trays 320 in the feeding area G1 are stacked vertically under the guidance of the feeding stack rod 312, and the locking buckle 311 is engaged with the slot 321 of the bottom tray 320 to lock and suspend the entire stack of trays 320; the receiving area G3 is in an empty state, waiting to receive empty trays 320.

[0048] During material feeding, the conveying unit 330 drives the base support 310 to move to the feeding area G1, and the locking buckle 311 releases the bottom full material tray 320, which falls onto the base support 310. Subsequently, the conveying unit 330 drives the base support 310 to move the full material tray 320 to the picking position G2, and the clamping unit 620 of the assembly component 600 picks up the horns 800 on the tray 320 one by one according to the position information.

[0049] After the horn 800 is removed, the conveying unit 330 drives the base support 310 to move the empty material tray 320 to the receiving area G3. The locking buckle 311 of the receiving area G3 engages with the slot 321 of the empty material tray 320, lifting and locking the empty material tray 320. Under the guidance of the receiving stacking rod 313, the empty material trays 320 are stacked upwards layer by layer. After the base support 310 is reset, it returns to the feeding area G1 to receive the next full material tray 320. This cycle repeats, thereby realizing the continuous supply of the horn 800 and the automatic recycling of the empty material trays 320.

[0050] Furthermore, refer to again Figure 4 Combined with reference Figure 10 , Figure 10This is a schematic diagram of the pose acquisition component 500 in this embodiment. The pose acquisition component 500 in this embodiment includes a support 510, a first imaging module 520, and a second imaging module 530. The support 510 is disposed on the base plate 110 of the frame 100, specifically, the support 510 spans across the top of the conveying component 200. The first imaging module 520 is disposed on the support 510 and located above the conveying component 200, and is used to acquire the pose information of the bottom shell 900 on the fixture 420 on the conveying component 200. The second imaging module 530 is disposed on the frame 100 and located between the conveying component 200 and the speaker supply component 300, and is used to acquire the pose information of the speaker 800 held by the gripping unit 620. Specifically, both the first camera module 520 and the second camera module 530 can be implemented using industrial cameras and corresponding light sources commonly used in the art. The industrial camera in the first camera module 520 is used to take a top-down shot of each bottom shell 900 on the fixture 420 below to obtain the pose information of the bottom shell 900. The industrial camera in the second camera module 530 is used to take a top-down shot of the speaker 800 when the gripping unit 620 grips the speaker 800 and moves it above the second camera module 530 to obtain the pose information of the speaker 800.

[0051] For details, please refer to again. Figure 4 and refer to Figure 11 , Figure 11 This is a schematic diagram of the assembly assembly in this embodiment. The frame 100 in this embodiment also includes a crossbeam 120 spanning the conveying assembly 200; specifically, the extension direction of the crossbeam 120 is perpendicular to the conveying direction of the conveying assembly 200. The assembly assembly 600 in this embodiment includes a connecting plate 610, a clamping unit 620, a third power component 630, and a fourth power component 640. The connecting plate 610 is laterally movable on the crossbeam 120; the clamping unit 620 is vertically movable on the connecting plate 610 and is used to clamp the speaker 800; the third power component 630 is disposed on the crossbeam 120 and is used to drive the connecting plate 610 to move the clamping unit 620 laterally; the fourth power component 640 is disposed on the connecting plate 610 and is used to drive the clamping unit 620 to move vertically to assemble the speaker 800 into the corresponding base shell 900.

[0052] Furthermore, in some embodiments, the assembly assembly 600 also includes a fifth power member 650, which is disposed on the connecting plate 610 and is used to drive the gripping unit 620 to rotate around its own axis, so as to adjust the speaker 800 by means of the pose information of the bottom shell 900 and the speaker 800 obtained by the pose acquisition assembly 500.

[0053] The third power component 630 and the fourth power component 640 mentioned above can both be implemented using telescopic cylinders commonly used in the art, or using lead screw mechanisms commonly used in the art. The fifth power component 650 mentioned above can be implemented using rotary cylinders or motors commonly used in the art. As long as the corresponding driving function can be achieved, the specific structure of the third power component 630, the fourth power component 640, or the fifth power component 650 is not limited here.

[0054] The clamping unit 620 can be implemented using principles such as vacuum adsorption or mechanical clamping. Specifically, considering that the speaker 800 itself has magnetic attraction, the clamping unit 620 in this embodiment uses the magnetic attraction principle to clamp the speaker 800.

[0055] Specifically, refer to Figure 12 and Figure 13 , Figure 12 This is a front view of the gripping unit in the embodiments of this application. Figure 13 The gripping unit in the embodiments of this application is along Figure 12 A cross-sectional view along line AA. The gripping unit 620 in this embodiment includes a suction nozzle 621, which includes an outer cylinder 6211 and a magnetic shaft 6212. The magnetic shaft 6212 is axially and vertically disposed within the outer cylinder 6211. The end of the magnetic shaft 6212 has magnetic attraction, used to attract the speaker 800 and move the speaker 800 to a predetermined position within the bottom shell 900. The outer cylinder 6211 is used to abut against the speaker 800 when the magnetic shaft 6212 moves upward, so that the speaker 800 disengages from the magnetic shaft 6212 and is assembled into a predetermined position within the bottom shell 900.

[0056] Furthermore, in some embodiments, a notch 6213 adapted to the protrusion 810 of the horn is provided at the end of the magnetic shaft 6212 to reduce the magnetic contact area between the magnetic shaft 6212 and the horn 800, thereby facilitating the horn 800 to disengage from the magnetic shaft 6212 under the contact of the outer cylinder 6211.

[0057] Furthermore, the quality inspection component 700 in this embodiment includes an electrically connected detection unit 710 and a transfer unit 720; wherein, the detection unit 710 is used to detect whether the speaker 800 is assembled into a predetermined position within the base shell 900; the transfer unit 720 is used to transfer the corresponding base shell 900 to a predetermined defective product position when the detection result does not meet the requirements. Specifically, refer to... Figure 14 and Figure 15 , Figure 14 This is a schematic diagram of the quality inspection component in an embodiment of this application. Figure 15This is a front view of the quality inspection component in this embodiment. The quality inspection component 700 in this embodiment also includes a second guide rod 701, a second slide block 702, a positioning support 703, and a top rod 704. The second guide rod 701 is disposed on the frame 100 along the conveying direction of the conveying component 200. The second slide block 702 is slidably connected to the second guide rod 701 and can move along the second guide rod 701 in the conveying direction to inspect different bottom shells 900 on the fixture 420. The positioning support 703 is disposed on the second slide block 702 and is used to support and position the bottom shell 900 when the assembled bottom shell 900 arrives at the quality inspection station. The top rod 704 is disposed on the second slide block 702 and located below the positioning support 703, and is used to lift the fixture 420 and position it in a predetermined inspection position so that the inspection unit 710 can accurately inspect the bottom shell 900 inside the fixture.

[0058] Specifically, the detection unit 710 is mounted on the second slide block 702 and located above the positioning support 703, and includes an adjustment plate 713, a third imaging module 711, and a distance sensor 712. The adjustment plate 713 is vertically movable on the upper part of the second slide block 702; the third imaging module 711 is mounted on the adjustment plate 713 and located to one side of the distance sensor 712, and is used to capture images of the speaker 800 inside the bottom shell 900 to determine whether the speaker 800 is assembled to the predetermined position; the distance sensor 712 is mounted on the adjustment plate 713 and is used to detect whether the height of the speaker 800 after pressing meets the predetermined requirements, that is, to determine whether the speaker 800 has been completely pressed into the receiving cavity 910 of the bottom shell 900. The third imaging module 711 and the distance sensor 712 cooperate to comprehensively judge the assembly result from both position and height dimensions, which helps to improve the accuracy and reliability of the detection.

[0059] Furthermore, the transfer unit 720 is disposed on one side of the second slide 702, and includes a transfer cylinder 722 and a push plate 721. The output end of the transfer cylinder 722 is horizontal and perpendicular to the transfer direction of the transfer assembly 200. The output end of the transfer cylinder 722 is connected to the push plate 721. When the test result does not meet the requirements, the transfer cylinder 722 drives the push plate 721 to push it out horizontally, pushing the fixture 420 where the corresponding bottom shell 900 is located from the current inspection station to the predetermined defective product position, thereby realizing the automatic sorting of defective products.

[0060] Furthermore, refer to again Figure 4 and Figure 5In this embodiment, the production line 210 is further equipped with a position sensor 211, a limit rod 212, and a defective product placement platform 213. The position sensor 211 is located on both sides of the production line 210 and is used to detect the position of the fixture 420 on the production line 210 in real time. The position signal is fed back to the control system of the equipment to coordinate the orderly operation of various process components such as the bottom shell supply component 400, the intercepting positioning component 430, and the assembly component 600 according to the production rhythm, ensuring that the fixture 420 is accurately stopped at each predetermined work station. The limit rod 212 is located at the end of the production line 210 and is used to limit and block the fixture 420 that reaches the end of the production line 210, preventing the fixture 420 from exceeding the conveying range due to inertia. At the same time, it provides an end positioning reference for the return or unloading of the fixture 420. The defective product placement table 213 is located on one side of the production line 210 and close to the quality inspection component 700. It is used to receive the fixture 420 that carries the bottom shell 900 with non-compliant assembly quality pushed by the transfer unit 720 of the quality inspection component 700, thereby realizing the centralized collection and storage of defective products so that operators can take them out periodically for rework.

[0061] Through the above structure, the conveying component 200 can achieve continuous rotation of the bottom shell 900, and form a linkage control with each process component through the position sensor 211. It is also equipped with a limit rod 212 and a defective product placement platform 213 at the end, thereby constructing a complete conveying, positioning and defective product disposal function system, which provides a guarantee for the automated and stable operation of the whole machine.
