[0054] It should be noted that, in the present invention, after the OLED screen to be tested (referred to as the target part, the same below) is placed on the supporting part, the power mechanism 4 is used to control the clamping part and the supporting part on the clamping and centering mechanism 2 to move toward each other, thereby completing the automatic clamping and centering of the target part. In the process of automatic clamping and centering of the target part, the power mechanism 4 is also used to drive the pressure component 31 to intermittently apply pressure to the reset impact component 32, thereby completing the multi-point continuous impact test of the target part.

[0055] Specifically, Figure 3-4 and Figure 7 As shown, the clamping part includes two brackets 21 fixedly arranged on the top of the substrate 1 and a T-shaped slide 219 slidably installed on the top of the substrate 1, a limiting frame 22 is fixedly arranged between the top surfaces of the two brackets 21, an L-shaped bar 24 is fixedly connected to the top of the T-shaped slide 219, and one end of the L-shaped bar 24 is movably inserted into the inside of the limiting frame 22, and a clamping component is arranged on one end of the L-shaped bar 24 passing through the limiting frame 22;

[0057] A gear 25 is rotatably mounted between the two brackets 21 , and a tooth block 1 meshing with the gear 25 is fixedly disposed on the side of the L-shaped bar 24 and the movable bar 23 facing the gear 25 .

[0058] It should be noted that when the clamping portion and the supporting portion are in an initial separated state, the tooth block 1 on the opposite side of the L-shaped bar 24 and the movable bar 23 is meshed with the gear 25 at the same time, wherein, in the process of controlling the clamping portion and the supporting portion to move toward each other, the power source provided by the power mechanism 4 is used to push the L-shaped bar 24 to move in the direction of the supporting portion, and the horizontally moving L-shaped bar 24 drives the gear 25 to rotate, and then the rotating gear 25 is used to drive the movable bar 23 to move in the direction of the clamping portion, so that in the process of controlling the clamping portion and the supporting portion to move toward each other, the clamping assembly is used in conjunction with the pre-limiting assembly to automatically clamp and align the target part.

[0059] Specifically, Figure 2-6 As shown, the clamping assembly includes an L-shaped frame 26 fixed on both sides of the L-shaped strip 24, and strips 28 are provided on the opposite sides of the two L-shaped frames 26. A spring 29 is fixedly connected between the strip 28 and the corresponding L-shaped frame 26. A connecting rod 210 that movably penetrates the corresponding L-shaped frame 26 is fixedly provided on the inner side of the strip 28. A clamping plate 211 is fixedly connected to one end of the connecting rod 210 located on the inner side of the L-shaped frame 26, wherein the ends of the two clamping plates 211 close to the lifting portion are both expanded toward the opposite side of the two clamping plates 211 to guide the target part to enter between the two clamping plates 211. In addition, the clamping plates 211 can be set as follows Figure 3 The L-shaped structure shown can hold the upper end surface of the target part after clamping, so as to avoid dislocation of the target part during the impact test and affect the test effect;

[0060] The pre-limiting component includes a sink groove 215 opened on the upper end surface of the T-shaped seat 213, and the sink groove 215 is composed of a middle groove and side grooves on both sides of the middle groove. A swing plate 217 is rotatably installed inside each side groove. In order to ensure that the swing plates 217 inside the side grooves on both sides of the middle groove are normally deflected synchronously, it is necessary to set a fixed rotating rod in the middle of the side groove, and at the same time, a capsule-shaped sliding groove is opened in the middle of the swing plate 217, and the rotating rod is movably inserted into the sliding groove. In addition, each swing plate 217 is set to an L-shaped structure, and after the target part is placed on the T-shaped seat 213, the swing plate 217 that is swung into a horizontal state can just buckle the target part, so that the target can be smoothly taken out during the separation of the clamping part and the lifting part. A lifting plate 216 is provided inside the middle groove, and a spring 218 is fixedly connected between the lifting plate 216 and the inner bottom end surface of the middle groove. One end of each swing plate 217 close to the lifting plate 216 is hinged to the lifting plate 216.

[0061] It should be noted that when the spring 1 29 is in the natural state, the distance between the opposite sides of the two clamping plates 211 is smaller than the width of the target part, and when the spring 218 is in the natural state, the lifting plate 216 is pushed out of the middle groove and drives the swing plate 217 to swing around the rotating rod as the central axis. Figure 4 The inclined state shown in the figure, and after the target part is placed on the top of the T-shaped seat 213, the gravity of the target part itself can completely press the lifting plate 216 into the middle groove. At this time, the horizontal section of the L-shaped structure swing plate 217 is completely in the corresponding side groove. Then, as the lifting part and the clamping part move towards each other, the target part will enter the straight section along the inclined section on the clamping plate 211 under the restriction of the flat L-shaped structure swing plate 217, and in the process, the two clamping plates 211 are squeezed at the same time, and the clamping plate 211 is used to push the strip 28 at the corresponding position to move outward, and at the same time stretch the corresponding spring 29, and the restoring force generated when the spring 29 is stretched is used to align and clamp the target part.

The L-shaped bar 220 can drive the gear 225 to rotate during the synchronous movement with the L-shaped bar 1 24, thereby achieving the purpose of driving the rotating shaft 224 to rotate.

[0064] It should be noted that when the clamping part and the lifting part are in an initial separated state, the tooth block 2 on the L-shaped bar 220 and the gear 2 225 still maintain a meshing state, wherein, in the process of using the linkage accessories that move synchronously with the clamping part and the lifting part that move in opposite directions to drive the intermittent impact mechanism 3 to perform impact detection on the target part, when the L-shaped bar 1 24 moves toward the lifting part driven by the power source, it will drive the L-shaped bar 220 to move synchronously under the restriction of the U-shaped seat 221, and use the horizontally moving L-shaped bar 220 to drive the gear 2 225 to rotate, and at the same time drive the rotating shaft 224 to rotate.

[0068] It should be noted that one side of the inclined block 317 is set as an inclined arc surface structure and the other side is set as a straight surface structure, so that after the pressure-bearing section passes through the arc surface area and enters the straight surface area under the extrusion of the inclined block 317, the impact component 36 on the impact section will push the pressure-bearing section to rebound instantly under the action of the reset component 35, and generate an impact force on the corresponding area of ​​the target part, thereby achieving the purpose of impact detection of the target part.

[0069] Furthermore, the intermittent impact mechanism 3 also includes an oblique support 33 fixed on the inner side of each L-shaped plate 311, wherein the setting of the oblique support 33 can enhance the corner position of the L-shaped plate 311, and an arc plate 34 is fixed between two adjacent L-shaped plates 311, wherein a plurality of arc plates 34 connecting adjacent L-shaped plates 311 are connected in sequence to form a ring plate, which can simultaneously enhance the side position of each L-shaped plate 311 and ensure the pressure stability of the pressure component 31.

[0070] Specifically, Fig.11 As shown, the reset assembly 35 includes a sleeve 351 fixed on the top of the base plate 1 and a guide groove 353 opened on the bottom end surface of the pressure-bearing section, a sleeve rod 352 is movably sleeved inside the sleeve 351, a T-shaped column 354 is fixedly connected to the top of the sleeve rod 352, a spring three 356 sleeved on the outside of the sleeve rod 352 is fixedly connected between the T-shaped column 354 and the sleeve 351, and a ball 355 slidably installed in the guide groove 353 is fixedly connected to the top of the T-shaped column 354, wherein the setting of the ball 355 can ensure that the pressure-bearing section can swing up and down with the ball 355 as the center during the downward pressing process, and press the T-shaped column 354 downward to compress the spring three 356.

[0071] It should be noted that when the spring three 356 is in a natural state, the impact pendulum bar 322 is pushed to a horizontal state, and in the process of the spring three 356 being pressed and reset, the sleeve rod 352 is always kept inserted in the sleeve 351, wherein, in the process of the pressure section of the impact pendulum bar 322 swinging up and down under the action of the pressure-applying component 31, when the inclined arc surface on the inclined block 317 contacts the impact pendulum bar 322 as the shaft 224 rotates, as the shaft 224 continues to rotate, the inclined block 317 will squeeze the impact pendulum bar 322 downward, so that the pressure section of the impact pendulum bar 322 swings downward with the rotating core shaft on the side frame 321 as the center axis. In this process, as the pressure section of the impact pendulum bar 322 swings downward, the T-shaped column 354 will compress the spring three 356 downward, and the ball 355 will slide along the guide groove 353;

[0072] When the pressure-bearing section of the impact pendulum bar 322 passes through the curved surface area and enters the straight surface area under the pressure of the inclined block 317, the restoring force generated by the spring three 356 will push the T-shaped column 354 to move upward, allowing the ball 355 to push the pressure-bearing section of the impact pendulum bar 322 to move upward. Correspondingly, the impact section of the impact pendulum bar 322 will deflect downward and drive the impact component 36 thereon to perform an impact test on the target part.

[0073] Specifically, Figure 12-13 As shown, the impact assembly 36 includes a through slot 361 extending through the impact section and a groove 362 extending on the upper end surface of the impact section and communicating with the through slot. A frame plate 363 is movably provided inside the through slot 361. An impact head 364 is fixedly provided at the bottom end of the frame plate 363. The diameter of the impact head 364 is greater than the width of the through slot 361. The impact swing bar 322 can be used to resist the impact head 364 for a stable impact test. An adjustment component is provided between the frame plate 363 and the impact section.

[0074] The adjusting component includes slots 365 opened on both sides of the frame plate 363, and the two slots 365 are movably provided with a clamping plate 366 inside. A spring four 369 is fixedly connected between the opposite sides of the two clamping plates 366. Among them, the two clamping plates 366 can be inserted into the corresponding grooves 362 at their opposite ends under the action of the spring four 369. In addition, in order to ensure that the spring four 369 can be linearly telescopically extended and retracted in the horizontal direction, a telescopic sleeve rod can be added between the opposite sides of the two clamping plates 366 and sleeved inside the spring four 369. A U-shaped frame 367 is provided on the inner side of the frame plate 363, and a lifting frame 368 that movably passes through the top of the frame plate 363 is fixedly connected to the middle part of the inner side of the U-shaped frame 367.

[0075] It should be noted that when the spring four 369 is in a natural state, the opposite ends of the two clamps 366 pass through the notch 365 and enter the interior of the groove 362, and when the upper end surface of the impact head 364 fits with the lower end surface of the impact swing bar 322, the bottom end surface of the clamp 366 just contacts with the bottom end surface of the inner cavity of the corresponding groove 362. At the same time, right-angled triangular grooves are opened at the opposite ends of the two clamps 366, and the top end surfaces of the two ends of the U-shaped frame 367 are set as inclined surfaces, and the inclined surfaces on the U-shaped frame 367 fit with the inclined surfaces of the right-angled triangular grooves on the corresponding clamps 366.

[0076] When adjusting the impact position of the impact assembly 36, it is only necessary to adjust the initial state (such as Figure 12-13 The lifting frame 368 shown in the figure is lifted up, pulling the U-shaped frame 367 to move upward. During this process, as the U-shaped frame 367 gradually moves upward, the inclined surface on the U-shaped frame 367 will fit the inclined surface of the right-angled triangle groove on the corresponding card plate 366, thereby pushing the two card plates 366 to move towards each other and compressing the spring four 369 to allow the two card plates 366 to disengage from the corresponding grooves 362. Then, the position of the impact head 364 can be adjusted along the through groove 361. When the impact head 364 is adjusted to the corresponding position, the lifting frame 368 is released, so that the U-shaped frame 367 and the two card plates 366 can be positioned under the restoring force of the spring four 369, which is convenient for adjustment.

[0077] Specifically, Figure 7 As shown, the power mechanism 4 includes a seat block 41 fixed on the top of the base plate 1 and a T-shaped slide seat 219 slidably installed on the top of the base plate 1. A spring 5 46 is fixedly connected between the seat block 41 and the T-shaped slide seat 1 219. A trapezoidal plate 43 is slidably installed on the top of the T-shaped slide seat 219, wherein a straight groove is opened at the bottom end of the trapezoidal plate 43, and the top end of the T-shaped slide seat 219 extends into the straight groove to ensure that the trapezoidal plate 43 can stably push the L-shaped bar 24 to move. A mounting seat 44 is fixedly connected to the top of the trapezoidal plate 43, and one end of the mounting seat 44 is fixedly connected to a limiting frame 245 movably sleeved on the outside of the L-shaped bar 24.

[0078] An electric push rod 3 48 and an electric push rod 2 47 are fixedly installed on the top and one side of the seat block 41, respectively. The electric push rod 2 47 and the electric push rod 3 48 both use electric push rods of the model HB-DJ801. A round rod 49 is fixedly installed on the telescopic end of the electric push rod 3 48, and a guide wheel 410 is rotatably installed on the top of the round rod 49. The telescopic end of the electric push rod 2 47 is fixedly connected to the T-shaped slide seat 2 42, wherein the T-shaped slide seat 2 42 can be pulled to reciprocate by the electric push rod 2 47 to control the movement state of the L-shaped bar 1 24, and the electric push rod 3 48 can control the position state change between the guide wheel 410 and the trapezoidal plate 43. A guide plate 411 is fixedly installed on the outer side of the trapezoidal plate 43, and a wave guide groove 412 is opened on the trapezoidal plate 43 at the position corresponding to the round rod 49.

[0079] It should be noted that the side of the guide plate 411 away from the trapezoidal plate 43 is arranged parallel to the inclined surface of the trapezoidal plate 43, and the round rod 49 is arranged in contact with the surface of the guide plate 411, and the end of the guide plate 411 close to the wave guide groove 412 has a smooth transition with the wave guide groove 412. According to the position state between the guide wheel 410 and the trapezoidal plate 43, the working process can be divided into the following two processes:

[0080] Process 1: The guide wheel 410 contacts the inclined surface on the trapezoidal plate 43 under the control of the electric push rod 48.

[0081] During this process, when the electric push rod 2 47 pulls the T-shaped slide 2 42 to move toward the seat block 41, the trapezoidal plate 43 will move synchronously with the T-shaped slide 2 42 toward the seat block 41. At the same time, the limiting frame 2 45 will move synchronously along the area where the L-shaped bar 1 24 is located. However, due to the limitation of the guide wheel 410, the trapezoidal plate 43 will move along the straight groove toward the L-shaped bar 1 24, thereby pushing the L-shaped bar 1 24 and the L-shaped bar 2 220 to move synchronously away from the trapezoidal plate 43, and allowing the spring 5 46 to stretch, thereby completing the automatic clamping and centering of the target part, and completing the linear direction multi-point continuous impact test of the target part (see the above for the specific process);

[0082] After the test in this direction is completed, the electric push rod 2 47 will push the T-shaped slide 2 42 to move away from the seat block 41. At this time, when the infrared rangefinder 214 detects that the L-shaped bar 1 24 has retreated, it will send a signal to the control end, and the control end will control the servo motor 316 to drive the inclined block 317 to rotate 180°, so that the inclined arc surface on the inclined block 317 faces the direction of the trapezoidal plate 43. At the same time, the electric push rod 1 37 is controlled to pull the impact section of the impact pendulum bar 322 to move in the direction of the pressure section, so as to realize the linear direction multi-point continuous impact detection on the other side of the target part, and automatically release the clamping and centering state of the target part after the detection.

[0083] Process 2: The guide wheel 410 is located above the trapezoidal plate 43 under the control of the electric push rod 48.

[0084] During this process, when the T-shaped slide seat 42 is pulled by the electric push rod 47 to move toward the seat block 41, the movement process of the trapezoidal plate 43 is described in the forward direction of process 1, but because the round rod 49 moves along the inclined surface on the guide plate 411, the round rod 49 enters the wave guide groove 412 under the guidance of the guide plate 411. Then, as the trapezoidal plate 43 moves, it will drive the impact detection mechanism 3 to reciprocate and repeatedly detect a certain area on the target part. However, it should be noted that since the trapezoidal plate 43 swings left and right along the direction of the L-shaped bar 24 under the restriction of the wave guide groove 412, after the infrared rangefinder 214 detects that the trapezoidal plate 43 changes from the forward direction to the backward direction, it is also necessary to control the servo motor 316 to drive the inclined arc surface of the inclined block 317 to change direction. Similarly, after the infrared rangefinder 214 detects that the trapezoidal plate 43 changes from the backward direction to the forward direction, it is also necessary to control the inclined arc surface of the inclined block 317 to change direction.

[0085] Example 2

[0086] Refer to the instruction manual Figure 2-3 and Figure 5-6 According to an embodiment of the present invention, a detection device for an OLED screen of an electric vehicle is provided.

During this process, the roller brush 272 will continue to rotate under the drive of the motor to clean the particles remaining on the surface of the target part entering the area where the roller brush 272 is located. Then, as the target part continues to move forward, the airbags 278 at the corresponding positions will be pressed on both sides of the target part. At this time, the infrared rangefinder 214 The signal will be transmitted to the control end according to the position change of the L-shaped bar 24 detected, and the control end controls the electromagnetic valve 277 on the air inlet pipe 212 to close, and at the same time, the electromagnetic valve 277 on the air delivery pipe 274 to open, so that the target part squeezes the air in the air bag 278 during the squeezing of the air bag, and sprays it from the air outlet 279 to the surface of the target part, and blows away the particles that have been cleaned and fallen on the surface of the target part, so as to avoid the particles remaining on the surface of the target part affecting the result of the impact detection during the impact detection process;

[0090] On the contrary, as the target part gradually releases the pressure on the airbag 278, the control end will control the solenoid valve 277 on the air inlet pipe 212 to open, and at the same time, the solenoid valve 277 on the air supply pipe 274 will close to inflate the airbag 278 to ensure the smooth progress of the next round of impact detection process.
