DETAILED DESCRIPTION

[0021] In order to further explain the technical solution of the present utility model, it is described in detail through specific embodiments below.

[0022] like Figure 1 As shown, the utility model provides a high-precision multifunctional screening mechanism, including a support seat 1, a movable disk 2 movably embedded in the top surface of the support seat 1, the movable disk 2 can rotate horizontally on the top of the support seat 1 to drive the detection slot plate 4 and the electronic components to rotate and transport, and a controller 3 installed on the front end surface of the support seat 1. A plurality of detection slot plates 4 are locked and fixed on the top of the movable disk 2, and the detection slot plates 4 are electrically connected to the electronic components. A data processing module 6 and an analysis and comparison module 7 are arranged in the controller 3;

[0023] Among them, the detection slot plates 4 on the movable disk 2 are distributed in an annular shape with equal spacing, so that the detection slot plates 4 can stably and evenly transport the electronic components to the bottom of the industrial camera 58 for detection;

[0024] In this embodiment, the movable disk 2 is a circular structure, and a circular groove corresponding to the movable disk 2 is provided on the top surface of the support seat 1, thereby improving the stability of the movable disk 2 during rotation;

[0025] When in use, the electronic component to be tested and screened is placed in the test slot plate 4 and the electrodes of the electronic component are brought into contact with the electrodes of the test slot plate 4, so that the detection circuit and the electronic component form a loop, and the detection slot plate 4 detects the current in the loop to determine whether the electronic component is normal, and transmits the information to the controller 3, and the detection information is processed by the data processing module 6.

[0026] like Figure 1 and Figure 2 As shown, the present embodiment also includes a taking mechanism 5 disposed on the top of the support base 1, the taking mechanism 5 includes a fixing frame 51 and an L-shaped frame 57 respectively fixed to the rear end and the right end of the support base 1, a lifting cylinder 52 locked and fixed to the top of the fixing frame 51, a sliding frame 53 installed on the piston rod at the bottom of the lifting cylinder 52 and slidably connected to the front end surface of the fixing frame 51, and a rotating cylinder 54 fixed to the top of the sliding frame 53;

[0027] The support base 1 is provided with a conveying mechanism 59, which is used to provide a driving force for the horizontal rotation of the movable disk 2;

[0028] The piston rod at the bottom of the rotating cylinder 54 vertically moves through the sliding frame 53, and a rotating plate 55 located at the bottom of the sliding frame 53 is installed on the piston rod at the bottom of the rotating cylinder 54. A negative pressure suction cup 56 located vertically above the detection slot plate 4 is installed at one end of the bottom of the rotating plate 55 away from the rotating cylinder 54. The negative pressure suction cup 56 is connected to an external negative pressure machine through a hose, and the electronic components in the detection slot plate 4 are sucked out by the negative pressure machine and the negative pressure suction cup 56;

[0029] An industrial camera 58 for detecting electronic components is installed on the inner top of the L-shaped frame 57, and the industrial camera 58 and the detection slot plate 4 are both electrically connected to the controller 3;

[0030] Among them, two fixed frames 51 are installed on the support seat 1, and each fixed frame 51 is provided with a lifting cylinder 52, a sliding frame 53, a rotating cylinder 54, a rotating plate 55 and a negative pressure suction cup 56. The two negative pressure suction cups 56 are respectively facing the two detection slot plates 4 on the movable plate 2, so that the two negative pressure suction cups 56 can suck out qualified and unqualified electronic components respectively;

[0031] There is a gap between the industrial camera 58 and the top surface of the detection slot plate 4, and the industrial camera 58 is located vertically above the detection slot plate 4 at the right end, which improves the accuracy of the electronic components detected by the industrial camera 58.

[0032] like Figure 3 As shown, in this embodiment, the conveying mechanism 59 includes a motor 591 locked and fixed in the support seat 1, a half gear 592 installed on the output shaft at the top of the motor 591, and a gear 593 meshing with the half gear 592. The inner ring of the gear 593 is fixedly installed with a transmission shaft 594;

[0033] The transmission shaft 594 is connected to the middle of the bottom end surface of the movable disk 2, so that after the half gear 592 rotates one circle, the gear 593 cooperates with the transmission shaft 594 and the movable disk 2 to rotate the rear detection slot plate 4 to the position of the front detection slot plate 4;

[0034] The transmission shaft 594 is perpendicular to the bottom end surface of the movable disk 2, so that the transmission shaft 567 can drive the movable disk 2 to rotate horizontally stably;

[0035] When in use, the starting motor 591 drives the half gear 592 to rotate. When the half gear 592 rotates one circle, it drives the gear 593 to rotate horizontally by a corresponding angle. The gear 593 drives each detection slot plate 4 to rotate synchronously through the transmission shaft 594. The detection slot plate 4 drives the electronic component to rotate. After the electronic detection of whether the circuit is normal is completed, the electronic component rotates to the bottom of the industrial camera 58. The industrial camera 58 takes a high-precision picture of the outer surface of the electronic component and detects its outer surface, and transmits the information to the controller 3. The detected information is processed by the information processing module 6, and the image information of the qualified electronic components pre-stored in the controller 3 is compared by the analysis comparison module 7 to determine whether the outer surface of the electronic product is qualified, thereby realizing the multifunctional detection and screening of the electronic components.

[0036] During the detection process of the industrial camera 58, another electronic component is placed in the next detection slot plate 4, and the current in the detection circuit is continued to be used to determine whether the next electronic component is normal, and the motor 591 continues to work to transport the detection slot plate 4 to the bottom of the first negative pressure suction cup 56. When the circuit or outer surface of the detected electronic component is unqualified, the corresponding lifting cylinder 52 is controlled to drive the sliding frame 53, the rotating cylinder 54, the rotating plate 55 and the negative pressure suction cup 56 to move downward, and the negative pressure suction cup 56 moves downward to contact the upper surface of the electronic component. At this time, the external negative pressure machine is controlled to cooperate with the negative pressure suction cup 56 to absorb the unqualified electronic component, and then the lifting cylinder 52 can be controlled to drive the electronic component to move upward and out of the detection slot plate 4, and the rotating cylinder 54 can be controlled to drive the rotating plate 55, the negative pressure suction cup 56 and the electronic component to rotate horizontally to the external transportation device, and the electronic component is discharged through the negative pressure suction cup for transportation;

[0037] The motor 591 drives the movable disk 2 to continuously rotate to transfer the cutting slot plate 4 to the bottom of the next negative pressure suction cup 56, and controls the lifting cylinder 52, the rotating cylinder 54 and the external negative pressure equipment to suck out the qualified electronic components to another transportation equipment for transportation, so as to complete the detection and screening of the electronic components.
