[0030] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings. The contents mentioned in the implementation modes are not intended to limit the present invention.

[0031] See also Figures 1 to 9 The utility model provides a power-on detection mechanism with a protective function, comprising a frame 1, a partition assembly 2 arranged on the frame 1, and a detection assembly 3;

[0032] The interlayer assembly 2 includes a carrier plate 21, and the detection assembly 3 includes a pressing drive member 31, a pressing plate 32, and a probe assembly 33. The pressing drive member 31 is disposed on the carrier plate 21 and drives the pressing plate 32 to rise and fall. The probe assembly 33 is disposed on the carrier plate 21 and is located directly below the pressing plate 32. The probe assembly 33 is spaced apart from the pressing plate 32.

[0033] The probe assembly 33 includes a fixed plate 331, a detection needle 332 and a movable protective plate 335. The fixed plate 331 is arranged on the supporting plate 21, the detection needle 332 is arranged on the fixed plate 331, and the movable protective plate 335 is movably connected to the fixed plate. The movable protective plate 335 is provided with a through hole for the detection needle 332 to pass through.

[0034] Specifically, in this embodiment, after the electronic component 100 is processed, it enters the detection process. The frame 1 is welded by a plurality of square tubes, wherein the carrier plate 21 of the interlayer assembly 2 is fixed on the square tube for carrying the electronic component 100 to be detected, and a pressing drive 31 and a probe assembly 33 are installed on the side surface of the carrier plate 21. The pressing drive 31 drives the pressing plate 32 to move up and down to approach or move away from the probe assembly 33. When the external electronic component 100 is placed on the carrier plate 21, the pressing drive 31 drives the pressing plate 32 to move toward the direction of the probe assembly 33, and the edge of the external electronic component 100 is pressed on the pressing drive 31. Between the plate 32 and the probe assembly 33, the probe assembly 33 is energized to detect the electronic component 100 to achieve the purpose of accurate detection. Preferably, when the external workpiece 100 to be detected is placed on the supporting plate 21, the edge of the detected workpiece 100 is in contact with the upper surface of the movable protective plate 335. After the pressure plate 32 is pressed downward, the movable protective plate 335 moves downward, and the detection needle 332 extends out of the through hole and contacts with the surface of the detected workpiece 100. When the detection process is completed, the pressing drive 31 drives the pressure plate 32 to return, the movable protective plate 335, and the detection needle 332 retract into the through hole to complete the detection.

[0035] By setting up a detection component 3 composed of a pressing drive part 31, a pressing plate 32 and a probe component 33, and a probe component 33 composed of a fixed plate 331, a detection needle 332 and a movable protective plate 335, during the detection process, the pressing edge 32 presses the workpiece 100 to be detected on the upper surface of the probe component 33 to achieve full contact detection, thereby improving the stability of the detection quality. The movable protective plate 335 protects the detection needle 332, prolongs the service life of the detection needle 332, reduces production costs, and meets production requirements.

[0036] The probe assembly 33 also includes a reset member 333 and a limit member 334, the two ends of the reset member 333 are respectively connected to the fixed plate 331 and the movable protective plate 335, one end of the limit member 334 is fixedly connected to the fixed plate 331, and the other end of the limit member 334 is movably connected to the movable protective plate 335. When the pressure plate 32 is pressed downward, the movable protective plate 335 moves downward, the detection needle 332 extends out of the through hole and contacts the surface of the detection workpiece 100, and the reset member 333 is compressed at the same time, and enters the detection process. When the detection process is completed, the pressing drive member 31 drives the pressure plate 32 to return, the reset member 333 drives the movable protective plate 335 to reset, and the detection needle 332 retracts into the through hole. Under the action of the limit member 334, the movable protective plate 335 returns to the initial position to achieve the protection purpose.

[0037] There are several detection needles 332 and several through holes. One through hole is used for one detection needle 332 to pass through. The arrangement of multiple detection needles 332 can meet different detection requirements.

[0038] The probe assembly 33 further includes a needle fixing plate 336 , and the number of the needle fixing plates 336 is at least two. Each needle fixing plate 336 is installed with a plurality of the detection needles 332 , which is convenient for installation and control.

[0039] The interlayer assembly 2 further includes a conveying driving member 22 and a conveying belt 23. The conveying driving member 22 is disposed on the carrying plate 21 and drives the conveying belt 23 to move. The interlayer assembly 2 has the purpose of carrying and conveying, thereby improving production efficiency and reducing labor input.

[0040] The number of the interlayer components 2 is several, and the several interlayer components 2 are arranged on the frame 1 from top to bottom. Since the detection process takes a long time, compared with the previous and next processes, the detection process requires more stations to match the previous and next processes. The setting of the multi-layer interlayer components 2 meets the purpose of multiple stations while reducing the plane occupied space, thereby meeting the production requirements.

[0041] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The contents of this specification should not be understood as limiting the present invention.
