[0022] Embodiment 1

[0023] like Figure 1-Figure 4As shown, a memory stick test fixture proposed by the utility model includes a frame 1, a driving component A and a memory stick loading and unloading component. The frame 1 is rotatably connected to a detection platform 2. A plurality of slots 201 for detecting memory sticks are arranged in a ring array around the axis of the detection platform 2. A plurality of status displays 202 for indicating the test status of the memory sticks corresponding to the slots 201 are arranged on the detection platform 2. A feeding component 11, a discharging component A12 and a discharging component B13 are arranged in sequence in a ring array around the axis of the detection platform 2 on the frame 1. The feeding component 11 has the same structure as the discharging component A12 and the discharging component B13. The feeding component 11 includes a bracket 111, a roller A112, a roller B113, a conveyor belt 114 and a motor C115. The bracket 111 is connected to the frame 1. The rollers A112 and B113 are both rotatably connected to the bracket 111, and the roller B113 is close to the detection platform 2. The conveyor belt 114 is connected to the roller A112 and the roller B113 by transmission, and the motor C115 is connected to the bracket 111 and drives the roller A112 to rotate. The driving component A includes a motor A3, which is arranged at the bottom of the frame 1, and the output end of the motor A3 is connected to the center point of the bottom plate of the detection platform 2. The driving component A drives the detection platform 2 to rotate so that each slot 201 passes through the output position of the feeding component 11, the input position of the discharging component A12 and the output position of the discharging component B13 in sequence. Multiple groups of memory bar loading and unloading components are connected to the detection platform 2, and each group of memory bar loading and unloading components corresponds to the corresponding side slot 201 respectively. The memory bar loading and unloading components include a fixed frame 4, a slider 5, a hydraulic cylinder A6, a card frame 7 and a motor B8. The fixed frame 4 is connected to the detection platform 2, the slider 5 is slidably connected to the fixed frame 4, and the hydraulic cylinder A6 is connected to the fixed frame 4 and drives the slider 5 to slide on the fixed frame 4. The card frame 7 is rotatably connected to the slider 5, and the card frame 7 is provided with a card slot 701 for placing the memory bar. The motor B8 is connected to the slider 5 and drives the card frame 7 to flip. Two slide grooves 702 are symmetrically arranged on the card frame 7 about the card slot 701 and are both connected to the card slot 701. Flexible clamping blocks 9 are slidably arranged in the slide grooves 702. Two hydraulic cylinders B10 are symmetrically arranged on the card frame 7. The hydraulic cylinders B10 on both sides drive and connect the corresponding side flexible clamping blocks 9 respectively. The memory bar loading and unloading component grabs the memory bar to be tested on the output position of the feeding component 11 and inserts it into the slot 201 in the working state, and after the detection is completed, the tested memory bar is pulled out from the slot 201 and unloaded and placed on the corresponding discharge component A12 or discharge component B13.

[0024] In this embodiment, the memory sticks are placed one by one on the conveyor belt 114 of the feeding assembly 11 in the direction away from the detection table 2 in the plug-in direction, and the motor A3 is started. The motor A3 drives the detection table 2 to rotate until the vacant socket 201 faces the output end of the feeding assembly 11, and then the motor B8 drives the card rack 7 to rotate so that the card slot 701 of the card rack 7 faces the memory stick. Then the hydraulic cylinder A6 drives the slider 5 and drives the card rack 7 to move toward the memory stick until the memory stick is inserted into the card slot 701. Then the hydraulic cylinder B10 is started. The hydraulic cylinder B10 pushes the flexible clamping block 9 to clamp the memory stick. Then the card rack 7 is flipped over until the plug-in end of the memory stick faces the slot 201, and the hydraulic cylinder A6 drives the slider 5 and drives the card rack 7 to move toward the memory stick until the memory stick is inserted into the slot 701. The pressure cylinder A6 pulls back the card rack 7 until the memory stick is inserted into the slot 201 and the power is turned on. The detection table 2 detects the memory stick. If the detection fails, the motor A3 drives the detection table to rotate until the memory stick faces the discharge component A12. The card rack 7 first pulls the memory stick out of the slot 201, then flips the memory stick and moves it to the conveyor belt 114 of the discharge component A12. Then the flexible clamp 9 is released, and the conveyor belt 114 exports the unqualified memory stick separately. If the detection passes, the memory stick is placed on the conveyor belt 114 of the discharge component B13 and exported separately, thereby realizing automatic and rapid loading and unloading, as well as detection, and automatic classification after detection.

[0025] Embodiment 2

[0026] like Figure 4 As shown, the memory stick test fixture proposed by the utility model, compared with the first embodiment, has two rollers B113 and two conveyor belts 114, and the rollers B113 on both sides are respectively connected to the roller A112 through a conveyor belt 114 to set a channel between the conveyor belts 114 on both sides for the card rack 7 to extend and retract, and the width of the channel is less than the length of the memory stick, and the width of the channel is not less than the width of the card rack 7.

[0027] In this embodiment, in order to prevent the memory stick from falling from the end position of the conveyor belt 114 or being in a tilted state, the placement position of the memory stick on the conveyor belt 114 needs to be maintained in the flat section of the conveyor belt 114. The bracket 7 is inserted into the channel between the conveyor belts 114 on both sides, so that the memory stick can be smoothly removed from the conveyor belt 114 of the feeding component 11, and the memory stick that has been inspected can be smoothly placed on the conveyor belt 114 of the discharging component.

[0028] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
