Specific embodiments

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Example 1, please refer to Figures 1 - 3, A diode pin tensile force inspection and testing device in this embodiment includes a bottom plate 1. A tensile force detection mechanism is provided on the bottom plate 1. The tensile force detection mechanism includes a support plate 2 fixedly installed on the upper surface of the bottom plate 1 and two side plates 3. A placement groove 4 is formed on the upper surface of the support plate 2. Pin clamping grooves 5 communicating with the placement groove 4 are formed on the opposite surfaces of the support plate 2. An electric telescopic rod 6 is fixedly installed on one side surface of the side plate 3. The electric telescopic rod 6 is fixedly installed on the side surface of the side plate 3 close to the support plate 2. An installation plate 7 is fixedly installed at the end of the electric telescopic rod 6 away from the side plate 3. A tensile force sensor 8 is fixedly installed on the side surface of the installation plate 7 away from the electric telescopic rod 6. A fixing block 9 is fixedly installed on the side surface of the tensile force sensor 8 away from the installation plate 7. The support plate 2 is located between the two side plates 3. The positions of the placement groove 4 and the pin clamping grooves 5 correspond to the position of the fixing block 9, which is convenient for fixing the pin on the fixing block 9 while clamping the diode into the placement groove 4. A rectangular groove 10 is formed on the surface of the fixing block 9. A fixing screw 11 penetrating into the rectangular groove 10 is threadedly connected to the upper surface of the fixing block 9. A first toothed plate 12 is fixedly installed on the lower surface of the inner cavity of the rectangular groove 10. A second toothed plate 13 located above the first toothed plate 12 is movably installed in the inner cavity of the rectangular groove 10. Strip-shaped grooves 14 are formed on the opposite side surfaces of the inner cavity of the rectangular groove 10. Sliders 15 inserted into the strip-shaped grooves 14 are fixedly installed on the opposite side surfaces of the second toothed plate 13. The fixing screw 11 is in contact with the upper surface of the second toothed plate 13. The second toothed plate 13 and the first toothed plate 12 can be pressed together by the fixing screw 11 to clamp and fix the pin. Two installation grooves 16 are formed on the upper surface of the inner cavity of the rectangular groove 10. Springs 17 are fixedly installed in the installation grooves 16. The bottom of the spring 17 is fixedly connected to the upper surface of the second toothed plate 13. By setting the springs 17, it is convenient for the second toothed plate 13 to separate from the first toothed plate 12.

[0021] It should be noted that the tensile force sensor 8 in this embodiment is composed of components such as strain gauges, sensor chips, shells, and connecting cables. When a tensile force is applied to the diode pin, the strain gauge will undergo a slight deformation, which will cause a change in the resistance value inside the strain gauge. The sensor chip will measure this change in resistance value and convert it into a corresponding electrical signal for output.

[0022] It should be noted that the first toothed plate 12 and the second toothed plate 13 in this embodiment have the same shape and structure.

[0023] The working principle of the above embodiment is as follows:

[0024] During use, place the body of the diode into the placement slot 4 and snap the diode pins into the pin slot 5 so that the diode pins protrude from the placement slot 4. At the same time, drive the mounting plate 7 and the fixing block 9 to move towards the side close to the support plate 2 through the electric telescopic rod 6, so that the diode pins are inserted into the rectangular slot 10. At the same time, make the diode pins located between the first tooth plate 12 and the second tooth plate 13. Turn the fixing screw 11 to gradually extend the fixing screw 11 into the rectangular slot 10. By gradually extending the fixing screw 11, the second tooth plate 13 can be pushed closer to the first tooth plate 12 until the second tooth plate 13 and the first tooth plate 12 clamp and fix the pins. At this time, the spring 17 is stretched. Then, move the mounting plate 7 away from the support plate 2 through the electric telescopic rod 6. At this time, the diode pins can be pulled, and the force sensor 8 can measure the force when the diode pins are pulled.

[0025] Embodiment 2, on the basis of Embodiment 1, a threaded hole 18 communicating with the inner cavity of the rectangular slot 10 is opened on the upper surface of the fixing block 9, and the outer surface of the fixing screw 11 is threadedly connected with the inner surface of the threaded hole 18, which is convenient for adjusting the length of the fixing screw 11 in the rectangular slot 10 and the pressing force of the fixing screw 11 on the second tooth plate 13.

[0026] The control mode of the present utility model is controlled by a controller. The control circuit of the controller can be realized by simple programming by those skilled in the art. The provision of power also belongs to the common knowledge in the art. And the present utility model is mainly used to protect mechanical devices, so the control mode and circuit connection of the present utility model will not be explained in detail.

Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.
