[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-5 , the utility model provides an embodiment: a fixing device for production and testing of Bluetooth headsets, comprising a main frame 1 and a sub-support 2 arranged on one side of the main frame 1, and a support plate 3 is installed on the top of the sub-support 2 through three short columns, a negative pressure box 4 is rotatably installed on the top of the support plate 3, and a plurality of equally spaced ear column seats 5 are installed at the edge position of the top of the negative pressure box 4, a countersunk hole 501 is arranged inside the ear column seat 5, and an air hole for communicating with the negative pressure box 4 is installed at the bottom of the countersunk hole 501, and the diameter of the air hole is smaller than the diameter of the countersunk hole 501, a rotary joint 7 is installed at the bottom end of the sub-support 2, an exhaust pipe 701 is rotatably installed on the top end of the rotary joint 7, and the top end of the exhaust pipe 701 extends to the inside of the negative pressure box 4 and is fixedly connected to the negative pressure box 4, and a rotating drive unit 8 for driving the exhaust pipe 701 to rotate is installed on one side of the bottom end of the sub-support 2;

[0019] A right-angle elbow is installed at one end of the rotary joint 7 away from the auxiliary support 2, and a solenoid valve is installed at the air inlet of the right-angle elbow. The negative pressure box 4 and the ear column seat 5 fix the earphone workpiece by generating suction. This fixing method is stable and reliable, and can effectively prevent the earphone workpiece from being displaced or falling off during the detection process, thereby ensuring the accuracy of the detection result;

[0020] The rotation drive unit 8 includes a servo motor installed on one side of the bottom end of the auxiliary support 2, and a gear transmission structure installed at the output end of the servo motor for driving the air extraction pipe 701 to rotate. The servo motor in the rotation drive unit 8 drives the air extraction pipe 701 and the negative pressure box 4 to rotate through the gear transmission structure, thereby realizing the self-rotation and continuous detection of the earphone workpiece through the cooperation of the negative pressure box 4 and the rotation drive unit 8. This process can be carried out automatically without a lot of manual participation.

[0021] The top of the main frame 1 is provided with an earphone anti-deflection mechanism 6, which is used to assist the Bluetooth earphone workpiece in an upright state. The earphone anti-deflection mechanism 6 includes a cylinder 601 installed on the top wall of the main frame 1, and a Z-shaped sliding arm 602 slidably installed on the top of the main frame 1. Two symmetrical rubber protrusion seats 603 are installed on the outer wall of one side of the Z-shaped sliding arm 602 close to the negative pressure box 4, and the top of the piston rod of the cylinder 601 is fixedly connected to the outer wall of the other side of the Z-shaped sliding arm 602;

[0022] A rectangular cut-out portion for the Z-shaped slide arm 602 to slide is provided at the top of the main frame 1, and guide rails are installed on both sides of the top of the main frame 1. A slide table for sliding with the guide rails is installed at the bottom end of the Z-shaped slide arm 602. When the ear column seat 5 and the Bluetooth headset workpiece rotate to the corresponding detection station and no longer rotate, the headset anti-deflection mechanism 6 can be actuated, that is, the cylinder 601 drives the Z-shaped slide arm 602 to move toward the direction of the ear column seat 5 until the rubber protrusion seat 603 is located on both sides of the headset workpiece. The headset anti-deflection function is realized by the structural design of two symmetrical rubber protrusion seats 603 to ensure that the headset workpiece is in an upright and vertical state after being adsorbed by negative pressure.

[0023] When the embodiment of the present application is in use, the staff first places the device on the inspection station of the inspection equipment, and connects the air inlet of the rotary joint 7 to the external negative pressure vacuum pump through the solenoid valve. Then the staff places multiple Bluetooth headsets to be inspected on each ear column seat 5 simultaneously, so that the columnar structure of the Bluetooth headset is inserted into the countersunk hole 501 of the ear column seat 5. When the Bluetooth headset workpiece is stored, the staff turns on the external negative pressure vacuum pump and the solenoid valve. When the solenoid valve is in the normally open state, the negative pressure vacuum pump evacuates the interior of the negative pressure box 4 and the ear column seat 5 and generates negative pressure. The Bluetooth headset is firmly located in the countersunk hole 501 due to the suction force to ensure the clamping stability of the Bluetooth headset workpiece. Then the staff turns on the rotary drive unit 8, and the rotational power of the rotary drive unit 8 is transmitted to the exhaust pipe 701. Since the bottom end of the exhaust pipe 701 is rotatably connected to the rotary joint 7 and maintains a state of communication with the air cavity, and the top end of the exhaust pipe 701 extends to the inside of the negative pressure box 4 And it is fixedly connected to the negative pressure box 4, the rotating drive unit 8 drives the exhaust pipe 701 and the negative pressure box 4 to rotate, so that the ear column seat 5 with the Bluetooth headset workpiece rotates to the detection station of the detection equipment for the detection process, when the Bluetooth headset workpiece on the ear column seat 5 is detected, the rotating drive unit 8 continues to drive the negative pressure box 4 to rotate, so that the next Bluetooth headset workpiece is transferred to the detection station to achieve the purpose of continuous detection. The device is designed with negative pressure box 4, ear column seat 5 and rotating joint 7. The ear workpiece can be continuously fixed during the loading, unloading and inflation and deflation processes, and there is no need to wait for these operations to be completed before detection. This greatly reduces the waiting time of the detection equipment and improves production efficiency. The rotating drive unit 8 drives the negative pressure box 4 to rotate, so that the ear column seat 5 with the earphone workpiece adsorbed can continuously rotate to the detection equipment for detection. This design allows the detection process to be carried out continuously without waiting for the next earphone workpiece to be loaded.
