Description

Technical Field

[0001] This utility model relates to the field of speaker testing technology, and in particular to a speaker dual-test-position sorting machine. Background Technology

[0002] Currently, after loudspeakers are manufactured, their quality is generally tested before they can be output. This includes tests such as listening tests and speaker curve tests. After the tests are completed, good and defective products are screened based on the test results to improve the yield rate of loudspeakers leaving the factory.

[0003] However, in existing speaker testing, when multiple speakers need to be tested simultaneously, multiple test stations are usually set up. Each test station has a separate positioning structure, a separate testing structure, and a separate transfer structure. During testing, each test station performs a separate testing action without interfering with each other. This results in too many structural elements in the whole machine, making the whole machine complex and costly. Utility Model Content

[0030] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments:

[0031] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0033] like Figures 1-5 The illustrated dual-test-position sorting machine for loudspeakers includes a base 60 and a positioning assembly 10, a testing assembly 20, a loading assembly 30, a transfer assembly 40, and a unloading assembly 50, all mounted on the base 60. The positioning assembly 10 includes a positioning platform 11, a positioning test piece, and a positioning platform 11 drive. The positioning platform 11 has at least two positioning carriers 12 and at least two positioning carrier drive pieces 15. Both positioning carriers 12 are rotatably mounted on the positioning platform 11, and the at least two positioning carrier drive pieces 15 on the positioning platform 11 are configured one-to-one with the at least two positioning carriers 12, with each positioning carrier drive piece 15 driving each positioning carrier 12 to rotate. The at least two positioning carriers 12 are spaced apart in the Y-axis direction; the positioning platform 11 drive piece can drive the positioning platform 11 to move in the Y-axis direction; the positioning detection piece 13 is used to detect the positioning angle of the positioning carrier 12.

[0034] The test assembly 20 includes a test bench 21, a test mechanism 23, and a test drive component. The test bench 21 is provided with at least two test slots 22, which are spaced apart in the Y-axis direction. The test mechanism 23 is located above the test bench 21 and moves along the X-axis, Y-axis, and Z-axis directions under the drive of the test drive component.

[0035] The aforementioned loading assembly 30, transfer assembly 40, and unloading assembly 50 can be spaced apart on the base 60. In some embodiments, the loading assembly 30, transfer assembly 40, and unloading assembly 50 are spaced apart in the X-axis direction. The loading assembly 30 can clamp the workpiece onto the positioning platform 12 to load the horn; while the transfer assembly 40 clamps the workpiece from the positioning platform 12 and transfers it to the test slot 22, that is, the positioned horn on the positioning platform 12 is transferred to the test slot 22 of the test platform 21. The unloading assembly 50 can clamp the workpiece from the test slot 22 for unloading.

[0036] Based on the above structure, when using the dual-test-position sorting machine for horns of this invention, during horn testing, a horn can first be clamped onto one of the positioning platforms 12 of the positioning stage 11 via the feeding assembly 30. At this time, the positioning platform 12 can move under the positioning detection component 13 driven by the driving component of the positioning stage 11. The positioning platform 12 is then rotated to the horn testing angle by the driving component 15 of the positioning platform, and then the driving component 15 is stopped. Afterward, the driving component of the positioning stage 11 drives the positioning stage 11 to move one station along the Y-axis direction. At this time, another positioning platform 12 can move to the underside of the positioning detection component 13, and the loading component 30 will then pick up another horn and transfer it to another positioning platform 12 for rotational positioning. This process is repeated until at least two positioning platforms 12 are loaded with horns and positioned. Then, the transfer component 40 transfers the horns from at least two positioning platforms 12 to the respective test slots 22 of the test platform 21. That is, the same positioning platform 11 moves in the Y-axis direction, driving different positioning platforms 12 to move to the position of the positioning detection component 13 to complete the positioning, thus simplifying the positioning structure.

[0037] When testing the loudspeakers, each test slot 22 on the test bench 21 is equipped with a corresponding test mechanism 23. The test drive component drives the test mechanism 23 to move downwards corresponding to each test slot 22, so that each test mechanism 23 can simultaneously test the loudspeakers in each test slot 22. This can complete the positioning test of at least two loudspeakers and improve the testing efficiency.

[0038] It should be noted that the test drive component in this embodiment may include a test frame 24 and a test frame 24 drive structure. The test frame drive component 25 is mounted on the base 60 and can drive the test frame 24 to move in the X-axis, Y-axis and Z-axis directions. Multiple testers (such as automatic speaker testers, electroacoustic test systems, etc. in the prior art) can be set at the bottom of the test frame 24. Test probes are set on the corresponding testers. The test frame 24 moves in the Y-axis and X-axis directions so that the test probes of each tester correspond to the speaker in the test slot 22. Then, the test frame drive component 25 drives the test frame 24 to move downward in the Z-axis direction so that the test probes are electrically connected to the speaker to complete the test.

[0039] Of course, the aforementioned positioning detection component 13 can be a detection camera in the prior art, so that the detection camera can take pictures of the speaker on the positioning platform 12, thereby taking pictures of the rotation angle of the speaker on the positioning platform 12 for positioning.

[0040] Furthermore, the positioning stage 11 driving component includes a drive motor 161, a transmission belt 163, and two transmission wheels 162. The two transmission wheels 162 are rotatably mounted on the base 60, and the two ends of the transmission belt 163 are respectively wound around the two transmission wheels 162. The positioning stage 11 is connected to the horizontal transmission section between the two transmission wheels 162. The drive motor 161 is used to drive one of the transmission wheels 162 to rotate. In this way, the drive motor 161 can drive one of the transmission wheels 162 to rotate, while the other transmission wheel 162 can be driven by the transmission belt 163. The horizontal transmission belt 163 located between the two transmission wheels 162 can move in the Y-axis direction, thereby driving the positioning stage 11 connected to it to move.

[0041] Of course, the aforementioned positioning stage 11 driving component can also be implemented using existing electric slide structure, or other linear motion output structures such as driving cylinder or driving hydraulic cylinder.

[0042] More specifically, the aforementioned positioning component 10 also includes a protective cover 14, which covers the drive unit of the positioning platform 11 and can be connected to the base 60. A positioning opening is provided at the top of the protective cover 14. Two positioning platforms 12 extend through the positioning opening. Thus, the positioning platform 11 moves under the drive of the driving unit of the positioning platform 11. Since the positioning platforms 12 extend through the positioning opening, at least two positioning platforms 12 can move normally. The drive unit of the positioning platform 11 is located inside the protective cover 14, reducing the interference of external impurities of the base 60 on the drive structure inside the protective cover 14.

[0043] Furthermore, the feeding assembly 30 includes a feeding clamp 32, a feeding drive 33, and a feeding clamp 31. The feeding clamp 31 is located at the bottom end of the feeding clamp 32, and the feeding drive 33 is used to drive the feeding clamp 32 to move along the X-axis and Z-axis directions.

[0044] During the loading and clamping process, the loading drive 33 drives the loading clamping frame 32 to move in the X-axis direction, thereby driving the loading clamping component 31 to move between the loading station and the positioning table 11. The loading drive 33 drives the loading clamping frame 32 to move in the Z-axis direction, and the loading clamping component 31 can move up and down to achieve the clamping and lowering of the speaker.

[0045] It should be noted that the loading drive unit 33 includes an electric slide table set in the X-axis direction, a loading clamp 32 set on the electric slide table, an electric slide table set in the Z-axis direction on the loading clamp 32, and the aforementioned loading clamp 31 connected to the slide table of the electric slide table in the Z-axis direction, so that the loading clamp 31 can move in the X-axis direction and the Z-axis direction.

[0046] Furthermore, the loading assembly 30 also includes a loading conveying assembly, which includes a loading conveying disc 34 and a loading conveying drive 35. The loading conveying drive 35 is used to drive the loading conveying disc 34 to move along the Y-axis. When loading the horn, the workpiece tray with the horn can be placed on the loading conveying disc 34. The loading conveying drive 35 drives the loading conveying disc 34 to move, and the workpiece tray with the horn moves one position along the Y-axis, so that the loading clamping component 31 can directly clamp the horn on the loading conveying disc 34.

[0047] Furthermore, the feeding conveyor 34 is provided with at least two feeding positioning slots; the at least two feeding positioning slots are distributed at intervals in the X-axis direction and the Y-axis direction. At least two workpiece trays equipped with horns can be clamped through the feeding positioning slots. The workpiece trays are positioned after being assembled into the feeding positioning slots to prevent displacement during the clamping of the horns.

[0048] Furthermore, the unloading assembly 50 includes an unloading clamp 52, an unloading drive 53, and unloading clamping parts 51. At least two unloading clamping parts 51 are provided at the bottom end of the unloading clamp 52. The unloading drive 53 is used to drive the unloading clamp 52 to move along the X-axis and Z-axis directions.

[0049] During the unloading and clamping process, the unloading drive 53 drives the unloading clamping frame 52 to move in the X-axis direction, thereby driving the unloading clamping component 51 to move between the test table 21 and the unloading station. The unloading drive 53 drives the unloading clamping frame 52 to move in the Z-axis direction, and the unloading clamping component 51 can move up and down to achieve the clamping and unloading of the speaker.

[0050] Since the bottom of the unloading clamp 52 is provided with at least two unloading clamps 51, after the unloading clamp 52 moves above the test table 21, at least two unloading clamps 51 correspond one-to-one with at least two test slots 22 of the test table 21, thereby enabling the simultaneous unloading of the horns of at least two test slots 22 in the test table 21.

[0051] It should be noted that the unloading drive unit 53 includes an electric slide table set in the Y-axis direction, an unloading clamp 52 set on the electric slide table, an electric slide table set in the Z-axis direction on the unloading clamp 52, and the aforementioned unloading clamp 51 connected to the slide table of the electric slide table in the Z-axis direction, so that the unloading clamp 51 can move in the X-axis direction and the Z-axis direction.

[0052] Furthermore, the unloading assembly 50 also includes an unloading conveying assembly, which includes an unloading conveying disc 54 and an unloading conveying drive 55. The unloading conveying drive 55 is used to drive the unloading conveying disc 54 to move along the Y-axis direction.

[0053] When unloading horns, an empty workpiece pallet can be placed on the unloading conveyor 54. The unloading conveyor drive 55 drives the unloading conveyor 54 to move to the unloading station, where it receives the tested horns transferred by the unloading assembly 50. After the workpiece pallet at the previous station in the Y-axis direction is full, the unloading conveyor 54 can move one station along the Y-axis direction under the drive of the unloading conveyor. In this way, the next empty workpiece pallet can continue to receive the tested horns, achieving continuous unloading.

[0054] Furthermore, the unloading conveyor 54 is provided with at least two unloading positioning slots; the at least two unloading positioning slots are distributed at intervals in the X-axis direction and the Y-axis direction. At least two empty workpiece pallets can be clamped through the unloading positioning slots. The workpiece pallets are positioned after being assembled into the loading positioning slots to prevent displacement during the picking and placing of the horn.

[0055] Furthermore, the transfer assembly 40 includes a transfer gripper, a transfer drive 42, and transfer grippers 41. At least two transfer grippers 41 are provided at the bottom end of the transfer gripper, and the transfer drive 42 is used to drive the transfer gripper to move along the X-axis and Z-axis directions.

[0056] During the transfer and clamping process, the transfer drive 42 drives the transfer clamping frame to move in the X-axis direction, thereby driving the transfer clamping component 41 to move between the positioning stage 11 and the test stage 21. The transfer drive 42 drives the transfer clamping frame to move in the Z-axis direction, and the transfer clamping component 41 can move up and down to achieve the clamping and lowering of the speaker.

[0057] Since the bottom of the transfer gripper is provided with at least two transfer grippers 41, after the transfer gripper moves to the top of the positioning platform 11, the at least two transfer grippers 41 correspond one-to-one with the at least two positioning platforms 12 of the positioning platform 11. The at least two transfer grippers 41 can grip the positioning horns on the at least two positioning platforms 12, and then the transfer drive 42 drives the transfer gripper to move to the at least two test slots 22 of the test platform 21, and put them into the at least two test slots 22 respectively, so that the horns in the at least two test slots 22 in the test platform 21 can be transferred at the same time and tested.

[0058] It should be noted that the above-mentioned loading clamp 31, unloading clamp 51 and transfer clamp 41 can be vacuum suction cups from the prior art, so as to complete the picking and placing of the speaker with vacuum suction cups and reduce the scratching of the speaker during the picking and placing process.

[0059] For those skilled in the art, various other corresponding changes and modifications can be made based on the technical solutions and concepts described above, and all such changes and modifications should fall within the protection scope of the claims of this utility model.
