Description

Technical Field

[0001] This invention relates to the field of loudspeaker sorting equipment technology, and in particular to an automated quality sorting device for loudspeaker production lines. Background Technology

[0002] A loudspeaker is a transducer that converts electrical signals into sound signals, and its performance greatly affects sound quality. While the loudspeaker is the weakest component in an audio system, it is also one of the most crucial parts for achieving optimal sound effects. The principle of a loudspeaker is to transmit audio electrical energy through electromagnetic, piezoelectric, or electrostatic effects, causing its cone or diaphragm to vibrate and resonate with the surrounding air to produce sound.

[0003] Speaker quality is determined by the quality of the audio frequencies (low, mid, and high frequencies) emitted by the speaker. However, current technologies for testing speaker quality still have the following drawbacks: To test the quality of a speaker, it is necessary to first power it on so that it can produce sound. In the current technology, a special station is set up for manual power-on testing of the speaker. During this process, a conductive pen needs to be touched and connected to the speaker's input terminals. To ensure the stability of the connection, the speaker needs to be fixed first. After the test is completed, the tested speaker is removed, and then the next speaker is fixed and tested. This process is repeated until the speakers of good and poor quality are sorted and placed separately. 1. This method is not only cumbersome to operate, leading to reduced testing efficiency, but also wastes human resources and increases labor costs; 2. In addition, during manual power-on testing, the varying skill levels and force applied by operators can easily damage the speaker's input terminals, leading to speaker damage and losses. Summary of the Invention

[0004] The main objective of this invention is to provide an automated quality differentiation device for loudspeaker production lines, which can effectively solve the problems of low detection efficiency when manually testing loudspeakers and the potential damage to loudspeakers due to varying levels of operator skill during power-on testing.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: An automated quality sorting device for a loudspeaker production line includes four fixed plates, two prismatic drive rollers, several transport plates, a motor, a control box, several loudspeaker bodies, and collection boxes. The four fixed plates are arranged in pairs on the left and right sides.

A spring is provided between the outer surface of the two guide rods on the same side away from the T-shaped plate on the same side and the T-shaped plate on that side. Two guide rings are provided at the middle of the far ends of the two T-shaped plates. The inner surfaces of the two guide rings on the same side are provided with U-shaped guide rails that can slide relative to the guide rings. Rollers are provided at the middle of the far ends of the two U-shaped guide rails. A follow-up mechanism is provided at the end of the two guide rods on the same side near the middle of the transport plate.

[0009] Preferably, both of the following mechanisms include a T-shaped plate II. Each of the two T-shaped plates II has a conductive plate I on its upper part at the ends that are far apart from each other. Each of the two T-shaped plates II has a telescopic rod symmetrically arranged on the left and right sides at the ends that are close to each other. Each of the two telescopic rods on the same side has an arc-shaped rubber plate at the ends that are far away from the T-shaped plate II on the same side. Each of the two conductive plates I has a wire on the upper left side. Each of the two arc-shaped rubber plates has a conductive mechanism I on the upper left side. Each of the four telescopic rods has a spring II for driving the telescopic rod to extend.

[0010] Preferably, the conductive mechanism includes a guide plate, which is fixed to the upper end of an arc-shaped rubber plate on the same side. A guide groove is provided in the middle of the lower end of the guide plate. A conductive plate 2 slides on the inner surface of the guide groove. A spring 3 is provided between the upper end of the conductive plate 2 and the top wall of the guide groove cavity.

[0011] Preferably, the testing mechanism includes a concave plate, an audio tester is fixed in the middle of the top wall of the inner cavity of the concave plate, and conductive mechanisms are provided on the upper part of the front side wall and the upper part of the rear side wall of the inner cavity of the concave plate.

[0012] Preferably, the conductive mechanism two includes a housing, and the inner cavity of the housing is provided with a spring four and a moving rod. The spring four is located between the ends of the housing and the moving rod that are close to the inner surface of the concave plate. The ends of the two housings that are close to the audio tester are provided with a plurality of through holes in a circular array that communicate with the inner cavity of the housing on the same side. The ends of the two moving rods that are close to each other are provided with through holes that can rotate relative to the moving rods. The two through holes slide in the inner cavities of the two conductive plates respectively.

[0013] Preferably, the separating device includes a guide box, a diversion shell is provided at the lower end of the guide box, and transport boxes are symmetrically provided at the front and rear of the lower end of the diversion shell. A control mechanism is provided in the middle of the inner cavity of the diversion shell, and the outer surfaces of the two transport boxes are respectively provided on the upper right side of the two Y-shaped load-bearing frames.

[0014] Preferably, the control mechanism consists of a baffle and a second motor.

The second motor is located in the middle of the upper end of the diversion housing, and the output end of the second motor is connected to the baffle through a coupling to control the rotation of the baffle.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention completely eliminates the manual power-on testing step. The speaker body is placed on the upper end of the limiting semi-ring using external machinery. The clamping device is moved by the control box. Under the action of the track, the clamping device clamps and drags the speaker body. After the position of the moving test mechanism is reached, the audio tester sends current through the conductive mechanism to the inside of the speaker body, causing the speaker body to produce audio. The audio tester judges the audio and transmits the result to the control box. Based on this result, the control box sends a command to the second motor, which controls the baffle to rotate. The baffle closes one of the passages in the inner cavity of the split housing, and the speaker body slides through the other passage to the inner cavity of the collection box for collection. The whole process is a streamlined operation, which improves testing efficiency and reduces labor costs.

[0016] 2. In this invention, two arc-shaped rubber plates clamp the speaker body under the action of a track. During the clamping process, the two arc-shaped rubber plates rotate. At this time, the two conductive plates move to below the two terminals at the input end of the speaker body. Then, under the control of the control box, the clamping device continues to move. At this time, the magnetic plate generates magnetic force, which responds to the magnetic force on the speaker body, pulling the speaker body downward a certain distance, so that the two terminals at the input end of the speaker body are respectively attached to the two conductive plates. There is no manual intervention throughout the process. Under the action of the two conductive plates and the spring, the integrity of the two terminals at the input end of the speaker body can also be protected, the torque on them can be reduced, and thus the integrity of the speaker can be protected and losses can be reduced.

[0017] 3. In this invention, by setting several springs and arc-shaped rubber plates, the two arc-shaped rubber plates on the same side can be applied to speaker bodies of various sizes, further improving the versatility of the clamping device.

[0018] 4. In this invention, the spring and moving rod allow the through hole to be connected more tightly to the conductive plate on the same side, maintaining the integrity of the power supply, further ensuring the continuity during the testing of the speaker body, and improving the accuracy of the test results.

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0022] Example 1 like Figure 1-7 As shown, an automated quality sorting device for a loudspeaker production line includes four fixed plates 1, two prismatic drive rollers 2, several transport plates 5, a motor 3, a control box 15, several loudspeaker bodies 16, and a collection box 12. The four fixed plates 1 are arranged in pairs on the left and right sides respectively. The two prismatic drive rollers 2 are respectively located between the opposite faces of the two fixed plates 1 in each pair and can rotate relative to the fixed plates 1 on the same side. The motor 3 is located on the upper part of the rear end of the fixed plate 1 located on the left side to drive the prismatic drive roller 2 located on the left side to rotate. The several transport plates 5 are connected in sequence by hinges and are collectively sleeved on the outer surface of the two prismatic drive rollers 2. The control box 15 is located at the front end of the fixed plate 1 located on the left side. The collection boxes 12 are all located on the right side of the fixed plate 1 located on the right side. It should be noted that the control box 15 is a common device, and the installation method and control method of its internal control circuit and electronic components are conventional designs in the prior art, which will not be described in detail in this embodiment.

[0023] As can be seen from the above, a material conveying device is formed by four fixed plates 1, two prismatic transmission rollers 2, a motor 3, and several conveying plates 5. When the control box 15 controls the motor 3 to run, it can drive the prismatic transmission rollers 2 to rotate the conveying plates 5. By using the octagonal shape of the prismatic transmission rollers 2 in conjunction with the several conveying plates 5, it can ensure that the clamping device 6 always maintains its complete shape, thus avoiding the deformation and damage of the clamping device 6 caused by the curved surface of the transmission wheel when connected to the traditional belt conveyor.

[0024] The inner cavity of the collection box 12 is divided into two parts, which are used to store speaker bodies 16 of different masses respectively.

[0025] As can be seen from the above, the combination of the above components can achieve the effect of transporting the speaker body 16. In conjunction with the above, it is necessary to ensure the stability of the speaker body 16 during transportation, while also fixing the position of the speaker body 16 so that the input terminals of the speaker body 16 can be connected to the external circuit.

[0026] Specifically, such as Figure 1 , 3 As shown, a support rod 7 is provided on the upper part between the two front fixed plates 1 and the two rear fixed plates 1 facing each other. Several evenly distributed uprights 8 are provided between the two support rods 7 facing each other. The upper ends of several uprights 8 on the same side are provided with a track 10. The upper left part of the two tracks 10 is provided with a support mechanism 11. The end of several transport plates 5 away from the midpoint of the line connecting the two prism-shaped transmission rollers 2 is provided with a clamping device 6. The upper end of the two right fixed plates 1 is provided with a testing mechanism 9 for detecting the quality of the speaker body 16. The upper right part of the two right fixed plates 1 is provided with a Y-shaped load-bearing frame 14. The right side of the outer surface of the two Y-shaped load-bearing frames 14 is provided with a distinguishing device 13. See Figure 13 , 14 The two orbitals 10 are symmetrically distributed, and each orbital 10 consists of three parts: a horizontally expanding segment on the far left, a stable segment in the middle, and an arc-shaped expanding segment on the far right. 1. Horizontal expansion section: The horizontal expansion section and the stable section have the same horizontal height, and the distance between the two horizontal expansion sections decreases linearly from left to right, so as to realize the purpose of driving the clamping device 6 to clamp the speaker body 16.

[0027] 2. Stable section: The distance between the two stable sections is the same from left to right, so as to keep the speaker body 16 stable during the clamping process of the clamping device 6.

[0028] 3. Arc-shaped expansion section: The arc-shaped expansion section has an arc-shaped structure. The radius of the arc-shaped expansion section is the same as the radius of the rotation path of the clamping device 6. The distance between the two arc-shaped expansion sections increases linearly from top to bottom in a clockwise direction. This is to release the binding and squeezing force on the clamping device 6, so that the clamping device 6 can gradually return to its initial state and release the clamping force on the speaker body 16, so as to send the speaker body 16 into the inner cavity of the guide box 131.

[0029] according to Figure 3 As shown, each clamping device 6 is divided into front and rear parts. When these two parts move relative to each other at the same time, they can clamp the speaker body 16 and transport the speaker body 16 and move its position simultaneously with the cooperation of the prism-shaped transmission roller 2 and the transport plate 5. As described above, during the operation of the device, the front and rear parts of the clamping device 6 move under the action of the prism-shaped transmission roller 2 and the transport plate 5, etc. When it moves to the horizontal expansion section on the left side of the two tracks 10, the special shape of the left side of the two tracks 10 drives the clamping device 6 to move, causing the front and rear parts of the clamping device 6 to move inward simultaneously until they merge into the stable section, achieving a completely stable clamping effect on the speaker body 16, and dragging the speaker body 16 to move. When it moves to the position of the testing mechanism 9, the speaker body 16 is tested by the testing mechanism 9, etc. The device is then inspected and moved to the position of the sorting device 13. At this time, the clamping device 6 is located at the rightmost arc-shaped expansion section of the track 10. Through the outward extension of both tracks 10, the front and rear of the clamping device 6 are opened and moved outward, releasing the clamping force applied to the speaker body 16. Subsequently, the speaker body 16 enters the interior of the sorting device 13. Under the control of the control box 15, the sorting device 13 sorts the speaker body 16, allowing the speaker body 16 to enter the cavity on the front or rear side of the collection box 12, thus completing the quality sorting of the speaker body 16.

[0030] Specifically, during the operation of the device, in order to increase the tightness of the connection between the conveyor plate 5 and the prismatic drive roller 2, refer to... Figure 1 , 2 In this embodiment, a connecting groove 21 is provided in the middle of the eight end faces of the outer surface of the two prismatic drive rollers 2, and a connecting block 51 adapted to the connecting groove 21 on the same side is provided in the middle of one end of a plurality of transport plates 5 near the midpoint of the line connecting the two prismatic drive rollers 2. Through the mutual cooperation between the connecting blocks 51 and the connecting grooves 21, the transport plates 5 can be firmly fixed on the outer surface of the prism-shaped transmission rollers 2. This not only increases the tightness of the connection between the transport plates 5 and the prism-shaped transmission rollers 2, but also prevents the transport plates 5 from falling off the outer surface of the two prism-shaped transmission rollers 2 during operation, thereby increasing the stability during the transport of the speaker body 16.

[0031] Specifically, to improve the accuracy of the clamping device 6 in initially clamping the speaker body 16, refer to... Figure 2 , 6 In this example, the supporting mechanism 11 includes two uprights 111. The two uprights 111 are respectively located on the upper left of the two tracks 10. The upper end of each of the two uprights 111 is provided with a horizontal plate 112. The two horizontal plates 112 are provided with a concave plate 113 between their opposite surfaces. The lower middle of the concave plate 113 is provided with a connecting rod 114. The lower end of the connecting rod 114 is provided with a tray 115. The upper left and upper right of the tray 115 are respectively provided with a limiting semi-ring 116 and a magnetic plate 117. As described above, the speaker body 16 is first placed on the upper end of the limiting semi-ring 116 to position it so that it is located in the middle left side of the control box 15. Then, the rotation of the prism-shaped transmission roller 2 drives the clamping device 6 to move. When the front and rear halves of the clamping device 6 are respectively in the horizontal expansion section of the left side of the inner cavity of the track 10 on the same side, the front and rear halves of the clamping device 6 begin to move closer to each other under the special shape of the track 10, and the magnet of the speaker body 16 is positioned between the two arc-shaped rubber plates 674. Between the two sides, the speaker body 16 is dragged to the right by two arc-shaped rubber plates 674 and slowly clamped to the upper end of the magnetic plate 117. Then, the magnetic plate 117 is energized by the control box 15, so that the magnetic plate 117 generates magnetic force and attracts the speaker body 16 to move downward a certain distance. After that, the magnetic plate 117 is de-energized and the magnetic force is released. Under the action of the prism-shaped transmission roller 2, the speaker body 16 continues to move to the right. The setting limit plate 119 can improve the accuracy of the placement position when placing the speaker body 16, thereby improving the accuracy of clamping. Specifically, in order to achieve the purpose of the upper clamping device 6 clamping the speaker body 16, see [reference needed]. Figure 3 In this embodiment, the clamping device 6 includes two T-shaped plates 61. Each of the two T-shaped plates 61 is provided with two symmetrical guide rods 62 at one end. The two guide rods 62 on the same side extend through the T-shaped plate 61 on the same side to the inside. The outer surface of the two guide rods 62 on the same side away from the T-shaped plate 61 on the same side is provided with a spring 63 between the side of the guide rods 62 on the same side away from the T-shaped plate 61 on the same side and the T-shaped plate 61 on that side. As can be seen from the above, the T-shaped plate 61 can increase the contact area between the clamping device 6 and the transport plate 5, thereby improving the stability of the T-shaped plate 61. The two guide rods 62 can guide the follower mechanism 67 during movement and improve the stability of the follower mechanism 67 during movement. The two springs 63 can make the roller 66 return to its initial position after separating from the inner surface of the track 10, so that the speaker body 16 can continue to be clamped and transported, and the clamping device 6 can be reused repeatedly. Furthermore, in order for the track 10 to perform the operation of driving the follower mechanism 67 to move inward during the operation of the device, see [reference needed]. Figure 3 , 4 In this embodiment, two guide rings 64 are provided at the middle of the two T-shaped plates 61 at their opposite ends. The inner surfaces of the two guide rings 64 on the same side are provided with U-shaped guide rails 65 that can slide relative to the guide rings 64. Rollers 66 are provided at the middle of the two U-shaped guide rails 65 at their opposite ends. Follow-up mechanisms 67 are provided at the middle of the two guide rods 62 on the same side near the middle of the transport plate 5. Both follow-up mechanisms 67 include T-shaped plates 671. Telescopic rods 673 are symmetrically provided at the middle of the two T-shaped plates 671 at their opposite ends.

[0032] As can be seen from the above, the guide ring 64 can play a guiding and fixing role during the movement of the U-shaped guide rail 65, so that the guide ring 64 can only move in the horizontal direction. When the roller 66 enters the inner cavity of the track 10 through the horizontal expansion section on the left side of the track 10, the distance between the two arc-shaped rubber plates 674 gradually shortens and gradually moves towards the speaker body 16 at the upper end of the limiting half ring 116, clamping the speaker body 16. Then, under the continuous drag of the transport plate 5, it merges into the stable section. At this time, the distance between the two arc-shaped rubber plates 674 remains stable and unchanged, and the clamping force on the speaker body 16 remains unchanged, moving steadily to the right.

[0033] Furthermore, to ensure that the speaker body 16 is not damaged during the clamping process by the two curved rubber plates 674, see [reference needed]. Figure 3 In this embodiment, the two telescopic rods 673 on the same side are provided with an arc-shaped rubber plate 674 at the end away from the T-shaped plate 671 on the same side, and the inner cavity of the four telescopic rods 673 is provided with a spring 676 for driving the telescopic rods 673 to extend. By using the telescopic rod 673 and the spring 676, the two arc-shaped rubber plates 674 can be adapted to various sizes of speaker bodies 16, and the rigid clamping force generated by the two arc-shaped rubber plates 674 during the clamping process is transformed into a flexible clamping force, thereby protecting the integrity of the speaker body 16.

[0034] Example 2 This embodiment adds speaker detection and classification operations to the first embodiment, thereby achieving the purpose of automatic speaker differentiation.

[0035] Specifically, to facilitate subsequent power-on testing, the input terminals of the speaker body 16 must always face one direction. (See [reference needed]). Figure 6 , 7 In this embodiment, a limiting plate 119 is provided at the lower front part of the right end of the connecting rod 114; After placing the speaker body 16 on the upper end of the limiting half ring 116, rotate the speaker body 16 counterclockwise. Then, when the input terminal of the speaker body 16 contacts the limiting plate 119, the limiting plate 119 blocks the speaker body 16 from rotating further, thus keeping the input terminal of the speaker body 16 in the same direction, which facilitates subsequent testing.

[0036] Specifically, to reduce the risk of damage to the input terminals of the speaker body 16 during testing, please refer to... Figure 3 and Figure 5 In this embodiment, a conductive mechanism 677 is provided on the upper left side of both arc-shaped rubber plates 674. The conductive mechanism 677 includes a guide plate 6771, which is fixed to the upper end of the arc-shaped rubber plate 674 on the same side. A guide groove 6772 is provided in the middle of the lower end of the guide plate 6771. A conductive plate 6774 slides on the inner surface of the guide groove 6772. A spring 6773 is provided between the upper end of the conductive plate 6774 and the top wall of the inner cavity of the guide groove 6772. As described above, after rotating the speaker body 16 so that the input terminals of the speaker body 16 face due left, and clamping the speaker body 16 with the two arc-shaped rubber plates 674 according to Embodiment 1, the two input terminals of the speaker body 16 are respectively located on the two conductive plates 6774. Under the drag of the transport plate 5, the speaker body 16 moves. At this time, under the control of the control box 15, the magnetic plate 117 is energized, generating magnetic force, which attracts the speaker body 16 downward, thereby making the two input terminals of the speaker body 16 tightly connected to the two conductive plates 6774, increasing the accuracy of the test process.

[0037] Specifically, to improve the accuracy of the test, please refer to... Figure 8 and Figure 9 In this embodiment, the testing mechanism 9 includes a concave plate 91, an audio tester 92 is fixed in the middle of the top wall of the inner cavity of the concave plate 91, and conductive mechanisms 93 are provided on the upper part of the front side wall and the upper part of the rear side wall of the inner cavity of the concave plate 91. The audio tester 92 mainly collects and tests the frequency response characteristics, harmonic distortion, signal-to-noise ratio, and dynamic range of the audio emitted by the speaker body 16, in order to test the quality of the speaker body 16 and thus determine whether the speaker body 16 is a qualified product. Using professional instruments can effectively improve the testing capabilities, thereby improving the factory quality of the speaker body 16 and reducing the return rate.

[0038] Specifically, to ensure that the current generated by the audio tester 92 can be applied to the speaker body 16, see [reference needed]. Figure 3 , 4 In embodiments 7 and 8, conductive plates 672 are provided on the upper part of the two T-shaped plates 671 at their opposite ends, and wires 675 are provided on the upper left part of the two conductive plates 672. The current generated by the audio tester 92 is received by the conductive plate 672 set on the T-shaped plate 671, and then transported to the two conductive plates 6774 through the wires 675, etc. Finally, it enters the speaker body 16 through the two input terminals of the speaker body 16, so that the speaker body 16 emits audio. The audio is then received by the audio tester 92, and the audio is analyzed to determine whether the speaker body 16 is a qualified product.

[0039] Furthermore, to improve the stability of the current received by the conductive plate 672, refer to... Figure 8 , 9 In this embodiment, the conductive mechanism 93 includes a housing 931. The inner cavity of the housing 931 is provided with a spring 932 and a moving rod 933. The spring 932 is located between the ends of the housing 931 and the moving rod 933 that are close to the inner surface of the concave plate 91. The ends of the two moving rods 933 that are close to each other are provided with through holes 934 that can rotate relative to the moving rods 933. The two through holes 934 slide in the inner cavities of the two conductive plates 672 respectively. The ends of the two housings 931 that are close to the audio tester 92 are each provided with a plurality of through holes 934 in a circular array that communicate with the inner cavity of the housing 931 on the same side.

[0040] As can be seen from the above, the spring 932 can push the moving rod 933 to move outward, thereby pushing the through hole 934 to move synchronously, so that it enters the inner cavity of the conductive plate 672 on the same side, guiding the current generated by the audio tester 92 to the conductive plate 672, and finally judging whether the speaker body 16 is a qualified product based on the above.

[0041] Specifically, in order to automatically distinguish between qualified and unqualified products identified by the audio testing instrument 92 and place them separately, please refer to... Figure 10 , 1112. The distinguishing device 13 includes a guide box 131, a diversion shell 132 at the lower end of the guide box 131, and transport boxes 133 symmetrically arranged at the front and rear of the lower end of the diversion shell 132. A control mechanism 134 is provided in the middle of the inner cavity of the diversion shell 132. The outer surfaces of the two transport boxes 133 are respectively located on the upper right side of the two Y-shaped load-bearing frames 14. The left front and rear sides of the guide box 131 are provided with grooves that communicate with the inner cavity of the guide box 131, so that after the two arc-shaped rubber plates 674 jointly drag the speaker body 16 into the inner cavity of the guide box 131, it can continue to rotate without interfering with the guide box 131. The diversion housing 132 is a housing with the left and right ends connected. The right end is divided into two parts and connected to two transport boxes 133 respectively. The connection between the left and right ends of the diversion housing 132 is controlled by the baffle 1342. After the speaker body 16 completes the testing phase, it moves to the arc-shaped expansion section on the right side of the track 10 under the drive of the transport plate 5, etc. Under the action of the four springs 63, the two arc-shaped rubber plates 674 move outward, releasing the fixation of the speaker body 16. Under the action of the guide box 131, the speaker body 16 enters the inner cavity of the guide box 131, guiding the guide box 131 during the movement.

[0042] Furthermore, the control mechanism 134 consists of a baffle 1342 and a second motor 1341. The baffle 1342 is located in the middle of the inner cavity of the diverter housing 132 and can rotate relative to the diverter housing 132 to control the inlet of the diverter housing 132 to communicate with its two outlets respectively. The second motor 1341 is located in the middle of the upper end of the diverter housing 132, and the output end of the second motor 1341 is connected to the baffle 1342 through a coupling to control the rotation of the baffle 1342, so that the guide box 131 can be connected to the two transport boxes 133 through the diverter housing 132 respectively, thereby allowing qualified and unqualified speaker bodies 16 to enter the front or rear of the inner cavity of the collection box 12 respectively.

[0043] In summary, the speaker body 16 is first placed on the upper end of the limiting semi-ring 116. Then, the motor 3 is controlled by the control box 15 to drive the prismatic transmission roller 2 to rotate several transport plates 5, thereby driving the clamping device 6 to move. When the clamping device 6 moves to the horizontal expansion section on the left side of the track 10 and enters the inner cavity of the track 10, the horizontal tilt of the horizontal expansion section of the track 10, driven by the transport plates 5, causes the clamping device 6 to move continuously to the right. At the same time, the two arc-shaped rubber plates 674 move closer to each other with the cooperation of the two rollers 66 and the track 10 on the same side, clamping the speaker body 16 on the upper end of the limiting semi-ring 116 and dragging the speaker body 16 to the right. When it moves into the inner cavity of the concave plate 91, the audio tester 9 is controlled by the control box 15. 2. During operation, the two through holes 934 enter the inner cavities of the two conductive plates 672 respectively, and the current generated by the audio tester 92 is transmitted to the inside of the speaker body 16 through the conductive plates 6774, etc., so that the speaker body 16 emits audio. The audio tester 92 then receives the audio and analyzes it to determine whether the current speaker body 16 is a qualified product. The result of the determination is transmitted to the control box 15. At this time, the control box 15 sends a signal to the motor 1341 based on this result. The motor 1341 controls the baffle 1342 to rotate, closing one path and allowing the speaker body 16 to enter the front of the collection box 12 through the other path. Conversely, the speaker body 16 enters the rear of the inner cavity of the collection box 12, thereby realizing the automatic differentiation of the speaker body 16.

[0044] It should be noted that in the above file, 15 controls the operation of 92 and 1341 respectively: 1. First, when the conductive mechanism 2 93 is connected to the speaker body 16 through the conductive plate 1 672, etc., and forms a complete circuit with the audio tester 92, the audio tester 92 sends an electrical signal to the control box 15. 2. Subsequently, the control box 15 sends a feedback electrical signal to the audio tester 92, causing the audio tester 92 to run; 3. Then, the audio tester 92 sends an electrical signal to the speaker body 16 and collects and processes the audio emitted by the speaker body 16; 4. Next, the audio tester 92 provides electrical signal feedback to the control box 15 with the processing results; 5. Finally, the control box 15 sends an electrical signal to the second motor 1341 according to the processing result, so that the second motor 1341 runs and drives the baffle 1342 to close one of the passages in the inner cavity of the diversion housing 132; so that the speaker body 16 that has completed the test enters the inner cavity of the collection box 12 through the other passage. The circuit layout and control methods involved in the electrical signal transmission and feedback between the control box 15, the audio tester 92 and the motor 1341 described above are all conventional designs in the prior art, and will not be described again in this embodiment.

[0045] It should be noted that the specific installation methods, circuit connection methods, and control methods of the motor 3, control box 15, and wire 675 used in the above embodiment one, as well as the audio tester 92 and motor 1341 used in the above embodiment two, are all conventional designs and will not be described in detail in this invention.
