Description

Technical Field

[0001] The utility model belongs to the technical field of component testing, and particularly relates to an automatic detection and packaging device for microphones.

Background Art

[0002] A microphone mainly consists of a PCB board with sound holes, a chip connected to the PCB board through a wire, and a housing that covers the PCB board and houses the chip inside. A capacitive silicon microphone chip mainly includes a thin and elastic diaphragm and a rigid backplate. The backplate and the diaphragm form a parallel plate capacitor. Sound pressure enters the interior of the microphone through the sound holes. The diaphragm will generate displacement under the action of the sound pressure, and the plate voltage will change with the movement of the diaphragm, thereby converting the sound signal into an electrical signal. The diaphragm is very sensitive to foreign objects, and even tiny foreign objects can affect signal transmission. Therefore, to ensure that the microphone has high reliability, high stability, and high consistency, it is necessary to prevent foreign objects from entering the interior, sound holes, and housing of the microphone before packaging. Therefore, the appearance detection of the microphone plays a crucial role in its high performance. Therefore, it is necessary to design relevant automated equipment.

[0003] For example, an automatic test, printing, and material collection device for a QFN chip disclosed in Chinese Patent Grant Publication No. CN210272269U includes an equipment cabinet. A turntable station is provided at the top of the equipment cabinet, and a vibrating disk feeding station, a turning station, a testing station, a laser station, a defective product discharging station, a packaging reel type material collection mechanism, and a tray type material collection mechanism are sequentially arranged along the outer circumference of the turntable station at the top of the equipment cabinet. Since a microphone has a direction, with the housing on the upper side and the PCB board with sound holes on the lower side, it is impossible to use a vibrating disk for feeding. Although a tray type material collection mechanism is also provided in the above solution, it does not explain how the tray discharges materials or the operating principle of the related structures during tray discharging. Moreover, it is not clearly stated in the above solution whether the tray type material collection mechanism can be used as a feeding mechanism. Additionally, the tray type material collection mechanism adopts a conventional design method, with a material tray feeding station, an empty material tray discharging station, and a material tray positioning station arranged between the material tray feeding station and the empty material tray discharging station. The handling mechanism takes materials from the material tray at the material tray positioning station, which results in the total length of the tray type material collection mechanism being greater than the total length when three trays are arranged in a straight line, causing the tray type material collection mechanism to occupy a large amount of space.

[0004] Therefore, it is necessary to provide an automatic detection and packaging device for microphones to solve the above technical problems.

When the second cylinder 1544 extends, the first support shaft 1545 moves to the uppermost end of the kidney-shaped sliding groove 15422, and the first clamping block 1542 rotates to clamp the end of the material tray inward.

[0047] The turntable module 2 includes a turntable 21, a driving motor 22 for driving the turntable 21 to rotate, and a mounting plate 23 arranged parallel to the turntable 21 and concentrically above it.

The clamping assembly 312 has been described in detail in the patent application No. CN202020130093.0, titled "A Three-Jaw Clamping Structure". Its working principle and structure are similar to those in this solution, so it will not be elaborated here; a first sensor 315 for detecting whether there is a product on the clamping mechanism is also provided on the clamping assembly 312.

[0050] The first detection module 32, the second detection module 34, and the third detection module 36 all include a positioning and clamping assembly 321 for positioning the product and a detection camera 322 for taking pictures of the product. The structures of the first detection module 32, the second detection module 34, and the third detection module 36 are similar.

[0053] The handling mechanism 7 includes an XZ-axis driving module 71, a suction frame 72 driven by the XZ-axis driving module 71 to move in the XZ direction, and a plurality of suction nozzles 73 fixed on the suction frame 72.

[0054] The transfer and conveying module 6 includes a first transfer and conveying module 61 and a second transfer and conveying module 62 that alternate in conveying. The structures of the first transfer and conveying module 61 and the second transfer and conveying module 62 are the same and both include an X-axis driving module 611, a support plate driven by the X-axis driving module 611 to move in the X direction, a third cylinder 613 fixed on the support plate, and a receiving plate 614 driven by the third cylinder 613 to move up and down. A receiving groove 615 for accommodating the product is provided on the receiving plate 614, and a second sensor 63 for detecting whether there is a product in the receiving groove 615 is also provided above the receiving plate 614.

[0055] In this embodiment, since it is necessary to suck away a row of products on the tray each time, several suction nozzles 73 are arranged in a row along the X direction, and the adsorption frame 72 is strip-shaped, which is convenient for extending into the product blanking position 12 to pick up materials. Correspondingly, the accommodating grooves 625 are also arranged in a row along the X direction, and the number of suction nozzles 73 and accommodating grooves 625 is the same as the number of products in a single column in the X direction on the tray. In other embodiments, the number and arrangement of the suction nozzles 73 and accommodating grooves 625 can be determined according to actual situations, which are not limited herein.

[0056] In order to reduce the movement stroke of the handling mechanism 7, an XZ-axis drive module 71 in the XZ direction is provided, and the transfer and conveying module 6 is provided with an X-axis drive module 621 in the X direction. Therefore, the suction nozzles 73 and the accommodating grooves 625 should be on the same horizontal line in the X direction so that the suction nozzles 73 can place the products into the accommodating grooves 625. After the suction nozzles 73 adsorb the products in the tray and move upward, they can directly move to the position directly above the accommodating grooves 625 by moving along the X direction. After the suction nozzles 73 move downward, they can place the products into the accommodating grooves 625. The design structure of this solution is more compact, occupies less space, and has a faster conveying rhythm.

[0057] In other embodiments, a drive module for moving in the Y direction can be added to the handling mechanism 7 and / or the transfer and conveying module 6, which is not limited herein.

[0058] When applying a microphone automatic detection and packaging device 100 provided by this solution, first place the tray loaded with products on the tray loading bin 11. The first material transfer module 16 moves the tray onto the tray conveyor line 14. When the front end of the tray enters the product unloading position 12, the first cylinder 1532 of the clamping and conveying module 15 drives the telescopic shaft 1531 to extend to block the tray. At the same time, the second cylinder 1544 extends, and the first support shaft 1545 moves to the uppermost end of the kidney-shaped chute 15422. The first clamping block 1542 rotates to clamp the end of the tray inward. The XZ-axis drive module 71 drives the adsorption frame 72 to drive a plurality of suction nozzles 73 to simultaneously adsorb a row of products and place them in the accommodation groove 615 on the first intermediate transfer module 61 or the second intermediate transfer module 62. The first motor 151 drives the blocking assembly 153 and the clamping assembly 154 to clamp the tray front and back, move forward one row. Wait for the suction nozzles 73 to adsorb the next row of products. When the products in the tray are adsorbed completely, when the second cylinder 1544 retracts, the first support shaft 1545 moves to the lowermost end of the kidney-shaped chute 15422, and the first clamping block 1542 rotates to open outward. The tray is conveyed forward by the conveyor line and lifted to the tray loading bin 11 by the second material transfer module; at the same time, the X-axis drive module 611 drives the receiving plate 614 to move to the detection station. The pushing assembly 25 presses down on the adsorption and handling assembly 24 to make the adsorption and handling assembly 24 adsorb a product. After the turntable 21 rotates, it is first located on the first alignment module 31. The first alignment module 31 clamps the product and aligns the product. The pushing assembly 25 presses down on the adsorption and handling assembly 24 to make the adsorption and handling assembly 24 adsorb the aligned product and place it on the first detection module 32 to take pictures and detect the appearance and size of the upper surface of the product. Defective products enter the first defective product box 41. The pushing assembly 25 presses down on the adsorption and handling assembly 24 to make the adsorption and handling assembly 24 adsorb the qualified products and place them in the second alignment module 33 to clamp and align the products. The products are moved to the second detection module 34 to take pictures and detect the appearance and size of the back of the product. The products are moved to the third alignment module 35 to clamp and align the products. The products are moved to the third detection module 36 to take pictures and detect the appearance and size of the side of the product. Defective products enter the second defective product box 42. After the detection is completed, the taping device 5 packages the qualified products after taping to complete the detection and packaging operations of the products.

[0059] The above are only some embodiments of the present invention. For those of ordinary skill in the art, without departing from the creative concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
