[0015] 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. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0016] See also Figure 1-Figure 2 A fully automatic rubber Shore hardness testing platform includes a Shore hardness tester with an electronic display function. The upper bracket of the Shore hardness tester is symmetrically provided with a ray end 1 and a receiving end 2. The receiving end 2 detects the rays from the ray end 1 reflected by the tray 3 of the Shore hardness tester. The tray 3 of the existing Shore hardness tester is usually glass. The positions of the ray end 1 and the receiving end 2 are adjusted so that the rays reflected by the tray 3 just reach the receiving end 2. When a test piece is placed on the tray 3, the rays emitted by the ray end 1 cannot be normally reflected to the receiving end 2. The receiving end 2 sends a signal that no rays are detected to the processing core 5 set in the base 4. The processing core 5 judges that there is a test piece on the tray 3 and starts the detection. When the test piece is taken away, the receiving end 2 receives the rays again. At this time, the receiving end 2 sends the signal of receiving the rays to the processing core 5. The processing core 5 judges that there is no test piece on the tray and stops the detection. That is, whether the test piece is on the tray 3 is judged by whether the receiving end 2 receives the rays from the ray end 1.

[0017] Furthermore, in order to prevent the light in the daily use environment from being reflected by the tray 3 and causing misjudgment of the receiving end 2, the ray end 1 uses a laser transmitter or a color light ray lamp, and the receiving end 2 uses a laser sensor or a color light sensor corresponding to the ray end 1.

[0018] The base 4 of the Shore hardness tester is provided with a motor 6, which drives the support rod 7 at the bottom of the tray 3 to telescopically move. Specifically, in the present embodiment, the motor 6 drives the support rod 7 to telescopically move through the connecting assembly 8, which includes a driving gear 801 fixedly connected to the output shaft of the motor 6, the driving gear 801 is connected to a driven gear 802 through a chain, the driven gear 802 is coaxially fixedly connected to a rotating rod 803, both ends of the rotating rod 803 are rotatably connected in the base 4, the outer circumferential surface of the rotating rod 803 is provided with teeth, and the teeth of the rotating rod 803 are meshed with the teeth arranged at the corresponding positions on the outer circumferential surface of the support rod 7. The driving gear 801 is driven to rotate by the motor 6, the driving gear 801 drives the driven gear 802 to rotate through the chain, the rotation of the driven gear 802 drives the rotating rod 803 to rotate, and the rotating rod 803 drives the support rod 7 to telescopically move through the teeth arranged on its outer circumferential surface. When the support rod 7 extends in a direction away from the base 4 , the tray 3 is pushed to move in the direction of the electronic counter 9 , thereby realizing the function of performing hardness testing on the testing piece on the tray 3 .

[0019] The ray end 1, the receiving end 2, the motor 6 and the electronic counter 9 of the electronic Shore hardness tester are all electrically connected to the processing core 5. The ray end 1 and the receiving end 2 are used to automatically determine whether there is a test piece on the tray 3. The current and voltage changes of the motor 6 are used to determine whether the motor 6 is stuck. When the motor 6 is stuck, it means that the tray 3 has risen to the top and the hardness test of the test piece has been completed; or the value of the electronic counter 9 does not change within a certain period of time to determine whether the tray 3 has risen to the top and the hardness test of the test piece has been completed.

[0020] A spring is provided at a position on the upper surface of the bottom of the base 4 corresponding to the bottom end surface of the support rod 7. After the hardness test of the test piece is completed, the processing core 5 turns off the motor 6, and the tray 3 falls toward the base 4 under the influence of its own gravity. At this time, the spring is used to buffer the impact force of the support rod 7 falling. One end of the spring can also be connected to the bottom end surface of the support rod 7, and the other end of the spring can be connected to the upper surface of the base 4. When the motor 6 is turned off, the support rod 7 automatically falls back to the initial position under the tension of the spring.

[0021] The processing core 5 is provided with an interface, and a connection hole penetrating to the interface is provided on the side of the base 4. The operator can insert the data line into the interface of the processing core 5 through the connection hole to perform programming adjustment. Furthermore, the processing core 5 is provided with a storage module, which can preset multiple detection modes, such as presetting the detection once or three times continuously after the startup detection.

[0022] Working principle: Place the utility model and start the power supply, place the detection piece on the tray 3, the receiving end 2 cannot detect the rays reflected from the ray end 1 by the tray 3, and sends the signal that no rays are detected to the processing core 5. The processing core judges that there is a piece to be detected on the tray 3, starts the motor 6 to rotate, and the driving gear 801 fixedly connected to the output shaft of the motor 6 rotates, and the driving gear 801 drives the driven gear 802 to rotate through the chain, and the driven gear 802 drives the rotating rod 803 to rotate, and the rotating rod 803 drives the support rod 7 to rise through the tooth pattern, and the support rod 7 pushes the tray 3 to move in the direction of the electronic counter 9. When the detection piece contacts the probe of the electronic counter 9, the detection piece is squeezed, and the tray 3 can no longer move, and the electronic counter 9 has measured that the hardness value of the detection piece no longer changes. After the processing core 5 detects that the hardness value does not change within the set time, it determines that the detection is over, turns off the motor 6, and the support rod 7 falls back to the initial position under the tension of the spring. At this time, the single detection ends and resets automatically until the detected object is taken away and the receiving end 2 detects the radiation again. The processing core 5 determines that the detection process is terminated until the receiving end 2 sends a signal that no radiation is detected again to start the next detection process.

[0023] When multiple tests are set, the processing core 5 starts the motor 6 again within the set time to perform a second test. During the multiple tests, when the test piece is taken away at any time, the receiving end 2 receives the radiation reflected by the tray 3 and sends the radiation reception signal to the processing core 5, and the processing core 5 determines that the test process is terminated.

Some or all of the modules may be selected according to actual needs to achieve the purpose of the solution of this embodiment.
