[0025] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments may be combined with each other. The present invention will be described in detail below with reference to the drawings and in conjunction with the embodiments.

[0026] It should be pointed out that the following detailed description is exemplary and is intended to provide further illustration of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present application belongs.

[0027] For ease of description, spatial relative terms such as "above", "over", "on the upper surface", "above" can be used herein to describe the spatial positional relationship of one device or feature to other devices or features as shown in the figures. It should be understood that the spatial relative terms are intended to encompass different orientations in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figure is inverted, the device described as "above" or "over" other devices or structures will then be positioned "below" or "beneath" other devices or structures. Thus, the exemplary term "above" can include both the orientations of "above" and "below". The device can also be positioned in other different ways, rotated 90 degrees or in other orientations, and corresponding interpretations are made for the spatial relative descriptions used herein.

[0028] Now, exemplary embodiments according to the present disclosure will be described in more detail with reference to the drawings. However, these exemplary embodiments can be implemented in many different forms and should not be construed as limited only to the embodiments set forth herein. It should be understood that these embodiments are provided so that the disclosure of the present application is thorough and complete, and the concept of these exemplary embodiments is fully conveyed to those of ordinary skill in the art. In the drawings, for clarity, the thickness of layers and regions is enlarged, and the same reference numerals are used to denote the same devices, and thus their descriptions will be omitted.

[0029] As Figures 1 to 5 shown, the tensile test device of this embodiment includes: a base 10, a traveling structure 20, and a force measuring mechanism 30. The traveling structure 20 is disposed on the base 10. The force measuring mechanism 30 includes a mounting frame 31, a tensile assembly 32, and a pressing assembly 33. The mounting frame 31 is mounted on the base 10, and both the tensile assembly 32 and the pressing assembly 33 are mounted on the mounting frame 31.

[0030] Applying the technical solution of this embodiment, the object to be tested is placed on the workbench of the base. Through the movement of the walking structure, the force measuring mechanism is moved above the object to be tested, and the object to be tested is pressed and fixed by the pressing component. The tension component is fixed to the component on the object to be tested, and the tension component applies a tension force. The object to be tested will not move under the pressing of the pressing component. In this way, under the combined action of the action force and the reaction force, the acting force that can be applied to the object to be tested can be measured. Both the pressing component and the tension component are arranged on the mounting rack, and only by moving the force measuring mechanism can the above test process be realized. The technical solution of this embodiment is simple to operate and has a high working efficiency.

[0031] As Figure 3 and Figure 4 shown, in the technical solution of this embodiment, the tension component 32 includes a driving part 321, a transmission part 322 and a clamping part 323. The driving part 321 is installed on the mounting rack 31, the clamping part 323 is installed on the transmission part 322, and the transmission part 322 cooperates with the clamping part 323 to drive the clamping part 323 to move. The above structure is relatively flexible to use and convenient to operate. Specifically, the transmission part 322 includes a reducer and a transmission rod. The driving part 321 is a driving motor. The output shaft of the driving motor is matched with the first end of the transmission rod through the reducer. The clamping part 323 is installed at the second end of the transmission rod. The output shaft of the driving motor and the transmission rod are both vertically arranged. The rotation of the output shaft of the driving motor is converted into the axial movement of the transmission rod through the reducer. The driving motor is a variable-frequency motor, so that the speed of the transmission rod during movement can be adjusted.

[0032] As Figure 4As shown, in the technical solution of this embodiment, the clamping portion 323 includes a first clamping arm 3231, a second clamping arm 3232, a fixing rod 3233, and an elastic member 3234. The first ends of the first clamping arm 3231 and the second clamping arm 3232 are pivotally mounted on the transmission portion 322. The elastic member 3234 is located between the first clamping arm 3231 and the second clamping arm 3232. The fixing rod 3233 has a clamping state that connects the first clamping arm 3231 and the second clamping arm 3232 together, so that the second end of the first clamping arm 3231 abuts against the second end of the second clamping arm 3232. Since the rotation axes of the first clamping arm 3231 and the second clamping arm 3232 are both at the first ends, the elastic member 3234 is provided to prevent a gap between the second end of the first clamping arm 3231 and the second end of the second clamping arm 3232, ensuring a tight clamping. Of course, other methods can also be used. For example, the second end of the first clamping arm 3231 is an inclined surface, that is, the thickness from the first end to the second end of the first clamping arm 3231 gradually increases. However, such a structure will result in a smaller contact area between the clamping portion and the component. In this embodiment, the mating surfaces of the second end of the first clamping arm 3231 and the second end of the second clamping arm 3232 are both rough planes, which makes the clamping of the component more stable and less likely to have relative displacement or even loosening. Specifically, the side of the second end of the first clamping arm 3231 facing the second clamping arm 3232 is a rough surface. The rough surface is a serrated structure. It should be noted that the rough surface can also be a rough surface with other structures to increase the friction force.

[0033] As Figure 4As shown, in the technical solution of this embodiment, the first clamping arm 3231 includes a first clamping plate and a first connecting plate. The second clamping arm 3232 has a second clamping plate and a second connecting plate. The first end of the first connecting plate has a first through hole, and the second end of the first connecting plate is connected to the plane of the first clamping plate facing the second clamping plate. The first end of the second connecting plate has a second through hole, and the second end of the second connecting plate is connected to the plane of the second clamping plate facing the first clamping plate. The connecting shaft passes through the first through hole and the second through hole to connect the first clamping arm 3231 and the second clamping arm 3232 to the transmission part 322. The first clamping plate has a long hole, and a threaded hole is provided on the second clamping plate. The fixing rod 3233 includes a rod body, a limiting plate and an operating rod. The first end of the rod body has an external thread adapted to the threaded hole. The operating rod is located at the second end of the rod body, and the limiting plate is located in the middle of the rod body. The fixing rod 3233 passes through the long hole and cooperates with the threaded hole. The elastic member 3234 is a spring, and the spring is sleeved on the circumferential outer side of the rod body. When the clamping part 323 is in the clamping state, the limiting plate presses against the plane of the first clamping plate away from the second clamping plate, and the spring is in a compressed state. The above structure has a low processing cost and is convenient to operate. The fixing rod 3233 can apply a pre-tightening force for clamping as needed. The structure of the long hole can adjust the position of the fixing rod 3233, and multiple threaded holes can also be provided as needed, so that multiple position selections can be made for the fixing rod 3233. The threaded hole is located in the middle of the second clamping plate in the vertical direction, and the two ends of the spring respectively press against between the first clamping plate and the second clamping plate. The operating rod is perpendicular to the rod body. The second end of the rod body has a through hole, and the operating rod is inserted into the through hole. The elastic force applied by the spring makes the clamping between the first clamping plate and the second clamping plate relatively firm. Specifically, there will be a processing error between the first clamping arm 3231 and the second clamping arm 3232 and the connecting shaft. Through the elastic force applied by the spring to the first clamping plate and the second clamping plate, the end of the second end of the first clamping arm 3231 and the end of the second end of the second clamping arm 3232 are pressed tightly without gaps. Of course, the gap between the first through hole, the second through hole and the connecting shaft can also be deliberately set. It should be noted that the side of the second end of the first clamping plate facing the second clamping plate has a first boss, and the height of the first boss is adapted to the length of the first connecting plate. The side of the second end of the second clamping plate facing the first clamping plate has a second boss, and the height of the second boss is adapted to the length of the second connecting plate, so that the first clamping arm 3231 and the second clamping arm 3232 are clamped more tightly. A torsion spring can also be provided between the first clamping arm 3231 and the second clamping arm 3232.

[0034] As Figure 3 and Figure 5As shown, in the technical solution of this embodiment, the pressing assembly 33 includes a pressing plate 331, a pressing rod 332, a pressing wrench 333, and a pressing transmission plate 334. The pressing wrench 333 is rotatably installed on the mounting bracket 31. The first end of the pressing transmission plate 334 is rotatably connected to the pressing wrench 333, the second end of the pressing transmission plate 334 is rotatably connected to the first end of the pressing rod 332, and the second end of the pressing rod 332 is fixedly connected to the upper surface of the pressing plate 331. The setting of the pressing plate 331 greatly increases the contact area between the tensile testing device and the object to be pressed (the object to be tested), making the force more balanced, the object to be pressed not easily damaged, and the detection more accurate. When in use, rotate the pressing wrench 333 upward, the pressing rod 332 drives the pressing plate 331 to press the object to be pressed downward. The pressing plate 331 has a relatively large contact area with the object to be pressed, so that the force on the object to be pressed is more uniform, and the object to be pressed is not easily damaged. The object to be pressed can be glass or a circuit board. The pressing plate 331 is made of polytetrafluoroethylene (PDFE), and the pressing plate 331 has an avoidance portion to avoid the clamping portion 323.

[0035] As Figure 5 shown, in the technical solution of this embodiment, the mounting bracket 31 includes a mounting plate and a convex plate. The convex plate is located on the side of the mounting plate. The pressing wrench 333 includes a wrench arm and a connecting arm. The first end of the wrench arm is connected to the first end of the connecting arm, and the convex plate is connected to the connection part of the wrench arm and the connecting arm. The wrench arm and the connecting arm are of an integral structure. The second end of the wrench arm is the operable free end, and the wrench arm and the connecting arm form a 90-degree angle. There are two convex plates, the pressing wrench 333 is located between the two convex plates, there are two pressing transmission plates 334, the connecting arm is located between the first ends of the two pressing transmission plates 334, and the pressing rod 332 is located between the second ends of the two pressing transmission plates 334. When in use, pull the pressing wrench 333 upward, the pressing plate 331 moves downward to press the object to be pressed. When the object to be pressed applies a force upward on the pressing plate 331, the pressing rod 332 and the pressing transmission plate 334 apply a force on the pressing wrench 333. The pressing wrench 333 can offset the force applied by the object to be pressed under the combined action of the mounting plate and the convex plate.

[0036] As Figure 1 and Figure 2As shown, in the technical solution of this embodiment, the walking structure 20 is an automatic walking structure or a manual walking structure. The setting of the walking structure 20 can achieve a larger placement range for the object to be pressed. In addition, the setting of the walking structure 20 also facilitates the static elimination of the object to be pressed by the tensile testing device. Taking the manual walking structure as an example, the base 10 includes side frames on both sides and a working platform. The working platform is connected between the two side frames, and the two side frames are arranged in parallel. The walking structure includes two first slide rails and a second slide rail. The two first slide rails are respectively located on the two side frames. The two ends of the second slide rail are located on the two first slide rails through slide ways. The force measuring mechanism 30 is installed on the second slide rail and can move along the second slide rail. The static eliminator 50 is arranged on the side of the second slide rail facing the workbench, so that the static eliminator 50 and the force measuring mechanism 30 will not interfere with each other. The length of the static eliminator 50 extends along the length of the second slide rail, so that the area of the object to be pressed can be larger, improving the versatility of the tensile testing device.

[0037] As Figure 4 and Figure 5 shown, in the technical solution of this embodiment, the tensile testing device further includes a control structure 40. The control structure 40 is electrically connected to the force measuring mechanism 30 to control the force measuring mechanism 30. The control structure 40 can realize the opening, stopping, walking of the walking structure and other operations of the device. This greatly improves the automation degree of the tensile testing device.

[0038] As Figure 1 and Figure 2 shown, in the technical solution of this embodiment, the tensile testing device further includes a static eliminator 50. The static eliminator 50 is arranged on the walking structure 20 to eliminate the static electricity of the object to be pressed. The setting of the static eliminator 50 greatly improves the service life of the tensile testing device and reduces the measurement error caused by static electricity.

[0039] As Figure 2 and Figure 5 shown, in the technical solution of this embodiment, the tensile testing device further includes a tensile force detection structure 60. The tensile force detection structure 60 is connected to the force measuring mechanism 30 to measure the acting force applied by the force measuring mechanism 30. The above structure improves the versatility of the tensile testing device. It should be noted that the tensile force detection structure 60 can measure the acting force applied by the tensile testing device in real time, which also improves the timeliness and accuracy of the measurement. Of course, if there is no tensile force detection structure 60, the method of setting a fixed acting force can be adopted, but in this case, the detection efficiency will be greatly reduced. In the technical solution of this embodiment, when detecting the acting force between the electronic components (components) on the glass and the glass, a breakage (destructive) experiment can be carried out, or a breakage experiment can be not carried out.

[0040] The present application also provides a tensile test method, which uses the above-mentioned tensile test device. The tensile test method includes the following steps: placing the object to be pressed on the workbench of the base 10. The traveling structure 20 moves to an appropriate position of the object to be pressed. The pressing assembly 33 presses the object to be pressed. The tensile assembly 32 clamps the components on the object to be pressed and performs a pulling test.
