[0002] A phototube is a basic optoelectronic conversion device based on the external photoelectric effect. The phototube can convert an optical signal into an electrical signal. The phototube is divided into two types: a vacuum phototube and an air-filled phototube. The typical structure of a phototube is to evacuate a spherical glass shell, coat a layer of optoelectronic material on the inner hemispherical surface as the cathode, and place a small spherical or small ring-shaped metal at the center of the sphere as the anode. In the existing production operations, the processed phototubes need to be tested through a phototube testing device to ensure the safety and stability of the subsequent use of the phototubes.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-6 , the present invention provides two technical solutions:

[0023] Embodiment 1

[0024] A phototube testing device includes a base 1. A multimeter 2 is installed on one side of the top end of the base 1. A workbench 3 is fixedly connected to the middle position on one side of the top end of the base 1. A clamping mechanism 4 is arranged on the top end of the workbench 3. A light-shielding shell 6 is arranged on the top end of the base 1. A camera 604 is installed on one side inside the light-shielding shell 6. A rotating mechanism 7 is arranged at the middle position of the top end of the light-shielding shell 6. When the multimeter 2 is connected to the pins of the phototube through a wire, the change of the input signal through the multimeter 2 will cause the change of the intensity of the optical signal emitted by the light-emitting end of the phototube, so as to confirm that the light-emitting end of the phototube can correctly respond to the change of the input signal. And the output signal of the receiving end of the phototube is measured through the multimeter 2. When the light is reflected or passes through the target, the receiving end will generate a corresponding electrical signal. The change of this signal is usually proportional to the intensity of the received optical signal. And through the camera 604, when the light-shielding shell 6 covers the top end of the base 1, the testing situation of the phototube inside the base 1 can be monitored in real time.

[0025] Slots 101 are arranged on both sides of the top end of the base 1. Insert blocks 601 inserted into the slots 101 are fixedly connected to both sides of the bottom end of the light-shielding shell 6. By inserting the insert blocks 601 at the bottom end of the light-shielding shell 6 into the slots 101 on the base 1, the light-shielding shell 6 can be installed on the top end of the base 1.

[0026] The rotating mechanism 7 includes first through holes 602 provided on both sides of the top end of the light-shielding shell 6. Positioning holes 603 are equidistantly and uniformly arranged at the middle position of the top end of the light-shielding shell 6. A rotating handle 701 is rotatably connected to the middle position of the top end of the light-shielding shell 6. A third pull rod 702 is slidably connected to the top end inside the rotating handle 701. The bottom end of the third pull rod 702 is fixedly connected to a movable disk 703. A positioning rod 704 inserted into the positioning hole 603 is fixedly connected to the middle position of the bottom end of the movable disk 703. The bottom end of the rotating handle 701 is fixedly connected to a turntable 8. Second through holes 801 are equidistantly and uniformly arranged inside the turntable 8. When the third pull rod 702 is pulled, the third pull rod 702 can drive the positioning rod 704 to move through the movable disk 703. When the positioning rod 704 is inserted into the positioning holes 603 at different positions on the light-shielding shell 6, the position fixing after the rotation of the rotating handle 701 can be completed. At the same time, the rotating handle 701 can drive the turntable 8 to rotate.

[0027] Embodiment 2

[0028] The main difference from Embodiment 1 is that:

[0029] An optoelectronic tube testing device, the clamping mechanism 4 includes fixed clamps 301 fixedly connected to both sides of the top end of the workbench 3 at equal distances and uniformly. A first pull rod 401 is slidably connected to one side outside the workbench 3. A movable block 402 is fixedly connected to one side of the first pull rod 401. A spring 403 is fixedly connected to one side of the movable block 402. A second pull rod 404 is fixedly connected to the side of the movable block 402 away from the spring 403. A movable clamp 5 is fixedly connected to the top end of the movable block 402. The movable block 402 is connected to the same kind of movable block 402 through the second pull rod 404. By pulling the first pull rod 401, the movable block 402 can be driven to move. At this time, the movable block 402 can squeeze the spring 403 on one side and drive the movable clamp 5 at the top end of the movable block 402 to move. When the first pull rod 401 is released, due to the reaction force of the spring 403 being squeezed, the movable clamp 5 can be pushed by the movable block 402 to reset. At the same time, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0030] In the use of the embodiment of the present application: Pull the first pull rod 401 on one side of the workbench 3, then the first pull rod 401 can squeeze the spring 403 through the movable block 402. At this time, the movable block 402 can drive the movable clamp 5 to move, and press the phototube to be tested against one side of the fixed clamp 301. Then release the first pull rod 401. Due to the reaction force of the spring 403 being squeezed, the movable clamp 5 can be pushed through the movable block 402 to complete the clamping work of the phototube. At this time, the multimeter 2 can be connected to the phototube through a wire for testing, and the light-shielding shell 6 is covered on the top of the base 1.
