The inner end of the limiting rod 148 contacts the lower part of the second positioning frame 144, and the limiting rod 148 can realize the limiting of the second positioning frame 144. There is a space between the movable plate 14 and the electric slide 5. A trigger assembly is provided. When the trigger assembly is operated, the trigger assembly can drive the movable plate 14 to move; the trigger assembly includes a trapezoidal plate 145 and a guide wheel 146. The lower parts of the four movable plates 14 are rotatably fitted with guide wheels 146. The lower parts of the front and rear side surfaces of the electric slide 5 are fixedly connected with trapezoidal plates 145. The trapezoidal plates 145 correspond to the guide wheels 146. When the trapezoidal plates 145 move and contact with the guide wheels 146, the trapezoidal plates 145 can drive the guide wheels 146 to move outward.

[0034] Initially, the compression spring 147 is in a compressed state. First, a proper amount of ink is poured into the housing 8 through the feeding tube 9. The ink in the housing 8 contacts the marking line 11. The batch rod is placed between the first positioning frames 143 on the left and right sides. Then the electric push rod 142 is started. The telescopic rod of the electric push rod 142 is extended to drive the first positioning frames 143 on the front and rear sides to move towards each other through the buffer spring 1431. The first positioning frame 143 drives the second positioning frames 144 on the front and rear sides to move towards each other. The second positioning frame 144 moves and disengages from the limit rod 148. Due to the action of the compression spring 147, the second positioning frame 144 swings and contacts the first positioning frame 143. The second positioning frame 144 and the first positioning frame 143 form a V-shaped frame. The second positioning frames 144 and the first positioning frames 143 on both sides move towards each other to center the batch rods. After the centering, the batch rods are in correspondence with the electric drive rods 4 on the left and right sides. The electric push rods 142 are closed. At this time, the single-rod cylinder 2 is started to drive the electric drive rods 4 on the left and right sides to move towards each other. The electric drive rods 4 move and contact with the ends of the batch rods. The electric drive rods 4 on the left and right sides clamp the batch rods, and the single-rod cylinder 2 is closed. The electric drive rods 4 are started to drive the batch rods to rotate. The image of the rotating batch rods is displayed on the prism 7. Then, the camera 6 is started to shoot and identify the image information of the batch rods affected by the reflection on the prism 7, and the image information is transmitted to the terminal for display. At the same time, the electric slide 5 is started to drive the camera 6 and the trapezoidal plate 145 to the right. The camera 6 moves to the right to fully detect the curvature of the batch rod. When the batch rod is bent, due to the action of the buffer spring 1431, the bent position of the batch rod will drive the first positioning frame 143 to move, and the image information recognized by the camera 6 will jitter. The camera 6 controls the front and rear electric winding wheels 10 to start through the control module. The front and rear electric winding wheels 10 are started to straighten the marking line 11, so that the marking line 11 moves upward and drives the guide rod 131 to move upward. The reset spring 132 is compressed, and the marking line 11 moves upward and first contacts with the wiping block 12. The wiping block 12 wipes off the excess ink on the marking line 11. After wiping off the excess ink, the marking line 11 continues to move upward and contacts with the bent position of the batch rod. The marking line 11 passes through the ink The ink is used to mark the bending position of the batch rod. After the batch rod is marked, the electric winding wheel 10 is closed. Due to the action of the reset spring 132, the guide rod 131 moves downward and resets, driving the marking line 11 to move downward and reset. The marking line 11 resets and contacts the ink in the shell 8 again, and this is repeated. Whenever the camera 6 captures and identifies the bending position of the batch rod, the marking line 11 can mark the bending position of the batch rod with ink, so as to facilitate the subsequent processing of the batch rod through the marked position, thereby improving the inspection efficiency and product quality. At the same time, the trapezoidal plate 145 moves to the right and contacts the guide wheel 146. The trapezoidal plate 145 drives the front and rear guide wheels 146 to move away from each other, and the guide wheels 146 drive the front and rear movable plates 14 to move away from each other.When the connecting spring 141 is compressed, the movable plate 14 drives the first positioning frames 143 on the front and rear sides to move away from each other through the electric push rod 142, and the first positioning frame 143 drives the second positioning frames 144 on the front and rear sides to move away from each other, and the first positioning frame 143 and the second positioning frame 144 move and disengage from the batch rod, and the first positioning frame 143 and the second positioning frame 144 avoid the movement of the electric slide 5 to prevent the movement of the electric slide 5 from blocking the bending detection of the image batch rod. As the trapezoidal plate 145 continues to move to the right and disengages from the guide wheel 146, due to the action of the connecting spring 141, the movable plate 14 drives the first positioning frames 143 on the front and rear sides to move and reset in the direction of approaching each other through the electric push rod 142, and the first positioning frame 143 drives the second positioning frames 144 on the front and rear sides to move and reset in the direction of approaching each other, and the first positioning frame 143 and the second positioning frame 144 continue to contact with the batch rod. When the electric slide 5 moves to the right to the maximum stroke, the camera 6 and the electric drive rod 4 are turned off, and the electric drive rod 4 stops driving the batch rod. The electric slide 5 is started to move to the left and reset. The electric slide 5 moves to the left and resets, driving the camera 6 and the trapezoidal plate 145 to move to the left and reset. The electric push rod 142 is started to drive the first positioning frames 143 on the front and rear sides to move away from each other and reset through the buffer spring 1431. The first positioning frame 143 drives the second positioning frames 144 on the front and rear sides to move away from each other. The second positioning frame 144 moves and contacts with the limiting rod 148. The limiting rod 148 limits the second positioning frame 144. The first positioning frame 143 continues to move. The second positioning frame 144 is moved and reset by the continued reset. Since the limiting rod 148 limits the second positioning frame 144, the limiting rod 148 pushes the second positioning frame 144 moving outward to swing and reset. The compression spring 147 is compressed, and then the single-rod cylinder 2 is started to drive the electric drive rods 4 on the left and right sides to move away from each other and reset. The electric drive rod 4 resets and disengages from the batch rod, and the batch rod falls between the first positioning frames 143 on the front and rear sides. The batch rod can be removed after detection, and the batch rod can be processed accordingly according to the marked position.

[0035] See also Figure 8 and Fig. 9As shown, the batch rod bending detection device for electric screwdriver research and development also includes a blanking component installed on the base 1, and the blanking component includes an n-type frame 15, a rotating drum 151, a rotating frame 152, an elastic clamp 153, a rotating component, a fixed frame 157, an electric lifting frame 158 and an electric clamp 159. The n-type frame 15 is fixedly connected to the base 1 symmetrically, and a fixed frame 157 is fixedly connected between the upper parts of the n-type frames 15 on the left and right sides. The electric lifting frame 158 is installed in the middle of the fixed frame 157, and the electric clamp 159 is symmetrically installed at the bottom of the electric lifting frame 158. When the electric clamp 159 moves, the electric clamp 159 can drive the batch rod to move for loading. The inner upper parts of the n-type frames 15 on the left and right sides are rotatably connected with the rotating drum 151, and the rotating drum 151 is rotatably sleeved on the fixed frame 1 57, the outer side surfaces of the left and right rotating drums 151 are fixedly sleeved with rotating frames 152, and the outer side surfaces of the left and right rotating drums 152 are evenly spaced along the circumferential direction. The elastic clamps 153 on the left and right sides correspond to each other, and the elastic clamps 153 can realize the placement of the batch rods. A rotating assembly is arranged between the n-shaped frame 15 and the rotating drum 151. When the rotating assembly is in operation, the rotating assembly can drive the rotating drum 151 to rotate; the rotating assembly includes a stepping motor 154, a spur gear 155 and an outer gear ring 156, and the outer side surfaces of the left and right rotating drums 151 are fixedly sleeved with outer gear rings 156, and the stepping motor 154 is installed in the middle of the upper part of the left and right n-shaped frames 15, and the output shaft end of the stepping motor 154 is fixedly connected with a spur gear 155, and the spur gear 155 is meshed with the outer gear ring 156.

[0036] When the curvature of the batch rod needs to be tested, an appropriate amount of the batch rod is first placed in the corresponding elastic clamps 153 on the left and right sides, and then the electric lifting frame 158 is started. The electric lifting frame 158 moves downward to drive the electric clamp 159 to move downward. The electric clamp 159 moves downward and contacts the batch rod directly below. The electric clamp 159 is started to clamp and fix the batch rod directly below. Then the electric clamp 159 continues to move downward to drive the batch rod directly below to move downward. Due to the elastic setting of the elastic clamp 153, the batch rod directly below moves downward and disengages from the elastic clamp 153. When the batch rod directly below continues to move downward to between the electric drive rods 4 on the left and right sides, the electric lifting frame 158 is closed, and the electric lifting frame 158 stops driving the batch rod to continue to move downward through the electric clamp 159. The electric clamp 159 is started to loosen the batch rod, and the batch rod falls downward to between the first positioning frames 143 on the front and rear sides. At this time, it can pass through the first positioning frame 1 43 and the second positioning frame 144 center the batch rod, and then start the electric lifting frame 158 to move upward and reset to drive the electric clamp 159 to move upward and reset, and then the curvature of the batch rod can be detected. At the same time, start the stepping motor 154 to rotate and drive the spur gear 155 to rotate, the spur gear 155 rotates and drives the outer gear ring 156 to rotate, the outer gear ring 156 rotates and drives the rotating drum 151 to rotate, the rotating drum 151 rotates and drives the rotating frame 152 to rotate, the rotating frame 152 rotates and drives the elastic clamp 153 to rotate, the elastic clamp 153 rotates and drives the batch rod to rotate, when the next batch rod rotates to the bottom, turn off the stepping motor 154, the rotating drum 151 stops driving the rotating frame 152 to rotate, the rotating frame 152 stops driving the batch rod to rotate through the elastic clamp 153, when the curvature detection of the batch rod is completed, the batch rod is removed, and the above operation can make the next batch rod move to between the first positioning frames 143 on the front and rear sides to complete the loading. In this way, the operator does not need to keep an eye on the batching rod to load the materials, thereby improving the loading efficiency.

[0037] See also Fig.10 As shown, the screwdriver rod bending detection device for R&D also includes a U-shaped rod 16 and a brush plate 17. The U-shaped rod 16 is symmetrically fixed to the front and rear of the middle part of the left n-shaped frame 15. The U-shaped rod 16 passes through the inner side of the electric slide 5. The brush plate 17 is fixed between the right ends of the U-shaped rods 16 on the front and rear sides. The brush plate 17 is in contact with the prism 7. When the prism 7 moves and contacts with the brush plate 17, the brush plate 17 can remove impurities attached to the prism 7.

[0038] When the electric slide 5 moves to the right, the electric slide 5 drives the prism 7 to move to the right, and the prism 7 moves to the right and contacts the brush plate 17, and the brush plate 17 removes impurities on the prism 7. After the impurities are removed, the prism 7 continues to move to the right for subsequent use, and the prism 7 continues to move to the right and the brush plate 17 is disengaged. When the prism 7 moves to the left to reset, the prism 7 contacts the brush plate 17 again, and the brush plate 17 removes impurities on the prism 7 again. In this way, it is possible to prevent impurities attached to the prism 7 from affecting the presentation of the image, thereby ensuring the accurate presentation of the image.
