Detailed Description

In order to make the technical solutions better understood by those skilled in the art, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.

Referring to fig. 1, an embodiment of the present application provides a detection apparatus 100 for detecting a speaker assembly 200 (as shown in fig. 3), where the speaker assembly 200 includes a bracket 201 and a speaker 203 disposed on the bracket. Wherein the speaker assembly 200 can be, but is not limited to, a part of an electronic device having a speaker, such as a mobile phone, a tablet computer, a camera, etc.

As shown in fig. 3, the speaker assembly 200 in this embodiment is described by taking a speaker assembly of a smart phone as an example, wherein the bracket 201 may be a fixing member of the speaker 203 for fixing the speaker 203 to a rear cover of the smart phone, and in some embodiments, the bracket 201 may simultaneously form a rear sound cavity of the speaker 203, so that when the bracket 201 is connected to the rear cover of the smart phone, the playing sound quality of the speaker 203 can be improved. Detecting the speaker assembly 200 is a process of the smart phone production and assembly process to ensure that the speaker assembly 200 is correctly assembled before assembling the speaker assembly 200 to the smart phone rear cover.

Further, the sound exit face (not shown) and the rear cavity (not shown) of the speaker 203 need to be separated during assembly to ensure that the speaker 203 is properly mounted. It should be noted that, the speaker 203 and the bracket 201 are correctly connected in a relationship that a back sound cavity of the speaker 203 is close to the bracket 201 and a sound outlet surface of the speaker 203 is far from the bracket 201. Therefore, the audio signal input to the speaker 203 can be transmitted to the outside through the rear sound cavity via the bracket 201, which is convenient for the speaker to be used. As an embodiment, the back cavity of the speaker 203 may form a larger back cavity with the bracket 201, thereby increasing the speaker effect of the speaker 203. In this embodiment, a calibration protrusion 2031 is disposed on one side of the back sound cavity of the speaker 203, and the calibration protrusion 2031 can be used as a marking feature during detection. The calibration protrusion 2031 is configured to detect whether the sound outlet surface and the rear sound cavity of the speaker 203 are correctly assembled to the bracket 201. Alternatively, the calibration protrusions 2031 are provided in pairs and spaced apart on both sides of the output end of the speaker 203. In a specific embodiment, the calibration protrusion 2031 may be a metal bump or a metal spring.

Referring to fig. 1, the inspection apparatus 100 includes a frame 10, a positioning mold 30, and an inspection assembly 50. The positioning mold 30 is disposed on the frame 10, and the positioning mold 30 is used for installing the bracket 201. The detecting element 50 includes a movable element 510 and a probe element 530, the movable element 510 is movably connected to the frame 10 and is disposed opposite to the positioning mold 30 at a distance, and the probe element 530 is connected to the movable element 510 and is disposed toward the positioning mold 30. The probe assembly 530 is used to detect the installation condition of the speaker assembly 200.

In the actual use process, the speaker assembly 200 is placed in the positioning mold 30 for fixing, the speaker 203 is placed towards the detection assembly 50, and then the distance between the movable member 510 and the positioning mold 30 is adjusted, so that the probe assembly 530 abuts against the speaker 203 for detection. When the movable element 510 moves to the limit position, it is determined whether the probe assembly 530 abuts against the calibration protrusion 2031, and the assembling state of the speaker 203 can be obtained. In this embodiment, the assembling state of the speaker 203 refers to the assembling state of the speaker 203 relative to the bracket 201, that is, the positional relationship between the sound emitting surface and the rear sound cavity of the speaker 203 and the bracket 201. The limit position is a position reached when the speaker assembly 200 is erroneously assembled, and the probe assembly 530 can abut or contact the calibration protrusion 2031 to determine whether the speaker assembly 200 is acceptable.

Further, when the probe assembly 530 abuts or contacts the calibration protrusion 2031, it indicates that the assembly state of the speaker 203 is an assembly error, the speaker assembly 200 is not qualified, and needs to be installed again; when the probe assembly 530 does not abut or contact the calibration protrusion 2031, it indicates that the assembly state of the speaker 203 is correct, and the speaker assembly 200 is qualified. In the description of the embodiment of the present application, only one working process of the detection device 100 to which the present application is applied is provided as reference, and the rest of the working processes are not described in detail.

As shown in fig. 1, the rack 10 includes a base 130 and a supporting frame 110 connected to the base 130.

In this embodiment, the supporting frame 110 includes a guiding post 111 and a supporting plate 113, and the guiding post 111 and the supporting plate 113 are connected and connected to the base 130 together. The number of the supporting plates 113 is plural, and the plurality of supporting plates 113 are connected to form a supporting structure with the base 130. Accordingly, the number of the guide posts 111 is plural, the plurality of guide posts 111 are all connected to the base substantially vertically, and the plurality of guide posts 111 are disposed at intervals from each other. In this embodiment, the movable element 510 is sleeved on the guiding column 111, and the guiding column 111 is used for guiding the movement track of the movable element 510.

In the embodiment shown in fig. 2, there are three support plates 113, the three support plates 113 are two vertical plates 1131 and one transverse plate 1132 respectively, the two vertical plates 1131 are connected to the base 130 at intervals, and the transverse plate 1132 is connected to one ends of the two vertical plates 1131 far away from the base 130 to form a "square" shape with the base 130. Further, there are two guiding studs 111, and the two guiding studs 111 are disposed on the base 130 at intervals, and the horizontal plate 1132 is connected to each other.

Referring to fig. 4, the positioning mold 30 is disposed on the base 130, and a curved groove 310 for positioning the bracket 201 is formed by recessing one side of the positioning mold 30 facing the movable member 510. The shape of the contoured groove 310 is substantially the same as the shape of the holder 201. In some embodiments, the size of the contour groove 310 is substantially the same as that of the support 201, and the support 201 can be inserted into or partially inserted into the contour groove 310, so that the position of the speaker assembly 200 is fixed during the detection process, and the detection result is prevented from being inaccurate due to the change of the position of the speaker assembly 200.

Referring to fig. 5, the movable member 510 is substantially plate-shaped, and the movable member 510 is movably connected to the guide post 111 and can relatively move close to or away from the positioning mold 30 along the guide post 111. In the present embodiment, a side surface of the movable member 510 facing the positioning mold 30 is provided with a mounting hole 511, and the mounting hole 511 is used for mounting the probe assembly 530.

Further, one end of the probe element 530 is inserted into the mounting hole 511 to fix the probe element 530 and the movable member 510. In one embodiment, the probe assembly 530 includes a needle cover 531, an elastic member (not shown), and a needle 533, wherein the needle 533 is connected to the needle cover 531, and the needle cover 531 is inserted into the mounting hole 511. The needle cover 531 is an inner hollow structure with an inner diameter larger than that of the needle core 533, and the needle cover 531 is sleeved on one end of the needle core 533 to prevent the needle core 533 from directly contacting the movable member 510. The elastic member may be a spring, and the elastic member is disposed in the needle sheath 531 and located between the needle core 533 and the needle sheath 531 to respectively form elastic abutting force to the needle sheath 531 and the needle core 533. When the plunger 533 is in contact with the speaker 203 and is bent or retracted, the resilient material in the sleeve 531 may slow or absorb the force applied to the plunger 533 and protect the plunger 533. In some embodiments, the elastic member may be an elastic material filled in the needle hub 531, such as rubber. In this embodiment, the limit position between the movable member 510 and the speaker assembly 200 can be adjusted by adjusting the length of the needle core 533 exposed from the needle cover 531. It should be noted that the limit position between the movable element 510 and the speaker assembly 200 refers to that when the speaker assembly 200 is assembled incorrectly, the probe assembly 530 can abut or contact the calibration protrusion 2031, and thus, it can be determined whether the speaker assembly 200 is qualified.

In this embodiment, the probe assembly 530 includes a first probe 535 and a second probe 537, and the first probe 535 and the second probe 537 are spaced apart from each other. Since the calibration protrusions 2031 at the output end of the speaker 203 are disposed in pairs and spaced apart from each other at two sides of the output end of the speaker 203, the first probe 535 and the second probe 537, which are disposed at intervals, should correspond to the calibration protrusions 2031, respectively, so as to better detect whether the speaker assembly 200 is assembled correctly.

The detection apparatus 100 further includes an actuating member 70, the actuating member 70 is disposed on the supporting frame 110, and the actuating member 70 is connected to and drives the movable member 510 to move relative to the supporting frame 110.

Alternatively, the driving member 70 is an element having a driving effect, such as a motor or a cylinder.

The detection device 100 provided by the present application, by providing the frame 10, the positioning mold 30, and the detection assembly 50, the detection assembly 50 includes a movable member 510 and a probe assembly 530. Wherein, the positioning mold 30 is used for placing the speaker assembly 200, and when the moving member 510 moves towards the direction of the positioning mold 30, the probe assembly 530 connected to the moving member 510 can be used for detecting whether the speaker assembly 200 is correctly installed, so that the detection process of the speaker assembly 200 is more intelligent, the detection result is more accurate, and the operation efficiency is improved while the quality of the speaker assembly 200 is ensured.

In one embodiment, the bracket 201 is further provided with a metal spring (not shown), and the metal spring is used for protecting the USB connector. It should be noted that, the metal elastic sheet is pressed on the support 201, and when the speaker assembly 200 is connected to the smartphone backshell, the metal elastic sheet can form an auxiliary fixing effect on the USB connector.

Referring to fig. 5, in the present embodiment, the detecting assembly 50 further includes a pressing head 550, the pressing head 550 is disposed on a side of the movable element 510 facing the positioning mold 30, and the pressing head 550 is used for a metal spring. The ram 550 may be attached to the moveable member 510 by a snap-fit connection, a threaded connection, or injection molding. When the movable member 510 moves to the limit position toward the positioning mold 30, the pressing head 550 approaches the positioning mold 30, and presses the metal dome. The metal elastic sheet can be matched with the bracket 201 more tightly in a pressing mode. It should be noted that the pressing head 550 is disposed at a position corresponding to the metal dome, so as to ensure that the pressing head 550 can press the metal dome after the moving member 510 moves. Therefore, when detecting whether the speaker assembly 200 is correctly installed, the detection device 100 can also press the metal elastic sheet, so that the operation steps are simplified, and the operation efficiency is improved.
