Description

Technical Field

[0001] The invention belongs to the technical field of component measurement and detection, and specifically relates to a length and thickness measurement device and a measurement method for components of laser equipment. Background Art

[0002] Length and thickness measuring devices are important tools for measuring the size of objects. They play a key role in many fields such as industrial production, quality control, and scientific research experiments. In the production of laser equipment parts, especially parts such as screws used to drive the movement of laser equipment, their thickness and length need to be detected by measuring devices after production and processing.

[0003] A patent with publication number CN117433437B discloses a workpiece thickness uniformity detection device, which uses a rotating table to install the workpiece to be detected, so that the central axis of the workpiece to be detected coincides with the rotation axis of the rotating table, and the light beam emitted by the light beam emitter is close to the workpiece to be detected, so that the light beam coincides with the edge portion of the workpiece to be detected, and the light beam emitted by the light beam emitter intersects with the outer ring wall of the workpiece to be detected. The light beam emitted by the light beam emitter is partially blocked by the workpiece to be detected, and the unblocked light beam is successfully irradiated to the convex lens and converged to the light intensity sensor. The controller is used to monitor the light intensity data detected by the light intensity sensor. If the workpiece to be detected is qualified, the thickness of the workpiece to be detected is uniform, and the contour of the workpiece to be detected is also a standard circle. Then, during the detection process, the blocking of the light beam by the workpiece to be detected will not change. If the light intensity data changes, it means that the thickness of the workpiece to be detected at the corresponding position has changed, or there are defects (convexities or depressions) on the surface of the outer ring wall, or the contour is distorted. At this time, the controller issues a prompt to prompt the detection personnel.

[0004] There are still some problems in the actual application of the above scheme. Usually, the detection head of the thickness meter is lifted up, and the laser equipment parts are placed under the thickness meter. The detection head of the thickness meter is used to abut the laser equipment parts, and the degree of sliding of the detection head inside the thickness meter is the thickness of the laser equipment parts, thereby completing the thickness detection of the screw.

[0023] S4. Packaging: After the length and thickness measurement of the parts are completed, the parts that meet the length and thickness standards are collected and sent to the packaging station for packaging, while those that do not meet the length and thickness standards are recycled.

[0024] The beneficial effects of the present invention are as follows:

[0025] 1. The laser equipment component length and thickness measuring device described in the present invention drives the material picking and conveying assembly to operate, and then automatically receives the abutment screw to convey it to the bottom of the pressing plate during the rotation of the material picking and conveying assembly, and then performs thickness detection on the screw. If a thinner component is to be detected, the U-shaped abutment block abuts and pushes the component to enter under the pressing plate, and the U-shaped abutment block will fit with the pressing plate and push the U-shaped abutment block to slide into the inner cavity of the groove, thereby avoiding the U-shaped abutment block from affecting the detection of the component. After the detection of the component is completed, the U-shaped abutment block pushes the component to slide out of the pressing plate, and then the first tension spring pulls the T-shaped slider to push the U-shaped abutment block to reset, thereby solving the problem that the existing laser equipment component length and thickness measuring device cannot automatically receive the component and drive the component to move to the bottom of the thickness meter for thickness detection when detecting the thickness of the component, resulting in low efficiency of component thickness detection.

[0026] 2. The length and thickness measuring device of laser equipment parts described in the present invention utilizes the production line to convey the screw into the storage box for storage and collection, and at the same time starts the conveyor belt to drive the U-shaped stop block to move. After the U-shaped stop block moves to the bottom of the storage box, it will abut against the push plate, thereby pushing the storage box to move. At the same time, the L-shaped toggle frame to pull the screw out of the storage box, and then after the U-shaped stop block is disengaged from the push plate, it will lift the screw to move upward. At the same time, the screw moves in the space formed by the storage box and the conveyor belt to prevent the screw from slipping out of the U-shaped stop block due to the lack of obstructions on one side of the conveyor belt. This solves the problem that the existing length and thickness measuring device of laser equipment parts cannot automatically pick up materials and control the amount of materials picked up when detecting the thickness of the screw. At the same time, when the screw is conveyed to the bottom of the thickness meter, it is auxiliary limited to prevent it from being separated from the material picking and conveying component, resulting in the screw being unable to be stably conveyed to the bottom of the thickness meter, thereby affecting the thickness detection accuracy and production efficiency of laser equipment parts.

[0027] 3. The laser equipment component length and thickness measuring device described in the present invention lifts the pressing plate through the screw rod, and at the same time pushes the T-shaped sliding column to drive the metering rod to slide in the sliding hole, and a photoelectric encoder is arranged on the inner wall of the sliding hole, and then during the sliding process of the metering rod, the photoelectric encoder can sense the position change of the metering rod, and convert it into an electrical signal and output it to the control console, and then the control console processes and analyzes the signal to obtain the degree of sliding of the metering rod, and the degree of sliding of the metering rod is the thickness of the screw. If the electronic thickness meter such as the photoelectric encoder is damaged, the position distance of the metering rod sliding out of the sliding hole can be observed by observing the metering scale outside the metering rod, and this distance is the thickness of the screw, thereby improving the practicality of the component thickness measuring device, and solving the problem that when the existing laser equipment component length and thickness measuring device performs thickness detection on the component, if the electronic thickness meter is damaged, the electronic thickness meter needs to be replaced or repaired before the thickness detection can be performed again, which not only causes delays in the component thickness detection link, but also affects the production efficiency of the component.

[0043] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods. Embodiment 1

[0044] like Figures 1 to 9 As shown, a length and thickness measuring device for laser equipment parts according to an embodiment of the present invention comprises a base 1, two fixing plates 2 are symmetrically fixedly connected to the upper end surface of the base 1, a fixing frame 14 is installed between the fixing plates 2, the fixing frame 14 is arranged in a trapezoidal shape, and a material taking and conveying assembly 3 is arranged between the fixing frames 14;

[0045] The material taking conveying assembly 3 includes a conveying belt 31 disposed between the fixing frames 14, and a plurality of grooves 33 are evenly formed on the outside of the conveying belt 31, and a U-shaped stopper 32 is slidably connected to the inner cavity of the plurality of grooves 33, so that the conveying belt 31 drives the U-shaped stopper 32 to rotate synchronously, and is used to receive the abutment screw 8 for conveying;

[0046] A mounting plate 11 is installed between the fixing frames 14, and a support block 10 is installed between the mounting plates 11, which is used to hold up the middle of the conveyor belt 31 to form a thickness detection platform, and a thickness measurement component 4 is installed on the upper end of the fixing plate 2;

[0047] The thickness measuring assembly 4 includes a support frame 41 installed on the upper end of the fixed plate 2, and a T-shaped sliding column 44 is slidably connected inside the upper end surface of the support frame 41. A pressing plate 48 is installed at the lower end of the T-shaped sliding column 44, and one end of the pressing plate 48 is tilted upward at sixty degrees so that the U-shaped stop block 32 can abut the screw rod 8 and enter the lower end of the pressing plate 48 to perform thickness detection.

[0048] Specifically, in the prior art, the detection head of the thickness meter is usually lifted, and the screw is placed under the thickness meter, and the detection head of the thickness meter is used to abut the screw, and then the number on the dial is observed, and this number is the thickness of the screw, so as to complete the thickness detection of the screw. However, this detection method cannot automatically detect the thickness of the screw, resulting in low screw thickness detection efficiency and cumbersome detection operation;

[0049] The present invention installs the fixing plate 2 at the tail end of the production line of laser equipment parts, and then drives the conveyor belt 31 to rotate, and then uses the conveyor belt 31 to drive the U-shaped stop block 32 to receive the screw 8 conveyed by the production line, and uses the U-shaped stop block 32 to push the screw 8 to move. Before the U-shaped stop block 32 drives the screw 8 to move below the pressing plate 48, one end of the pressing plate 48 is tilted upward at 60 degrees, and then the U-shaped stop block 32 pushes the screw 8 to move synchronously with the rotation of the conveyor belt 31, and the screw 8 easily enters between the tilted part of the pressing plate 48 and the conveyor belt 31, and then the pressing plate 48 is lifted by the screw 8 to move upward, so that the screw 8 moves to the bottom of the pressing plate 48, and the pressing plate 48 drives the T-shaped slide column 44 moves upward, and then observes the thickness of the screw 8 according to the position where the T-shaped slide column 44 slides out of the support frame 41 upward. In addition, a support block 10 is provided in the inner cavity of the conveyor belt 31, and the support block 10 holds up the middle part of the conveyor belt 31 to form a thickness detection platform, thereby avoiding the situation where the detection behind the screw 8 due to the uneven surface of the conveyor belt 31 is biased. At the same time, the support block 10 holds up the middle part of the conveyor belt 31, which will make the two sides of the conveyor belt 31 inclined at a certain angle, so that the inclined surface of the screw 8 affected by the conveyor belt 31 is always in contact with the U-shaped abutment block 32, thereby avoiding the two screws 8 from entering under the pressing plate 48 at the same time, causing the screw 8 with substandard thickness to affect the detection accuracy of the other screw 8, thereby solving the above-mentioned problem.

[0050] like Figure 1 , Figure 3 and Figure 8 As shown, four transmission shafts 38 are rotatably connected between the fixed frames 14, and multiple driven wheels 37 are fixed to the outside of the four transmission shafts 38. The driven wheels 37 are transmission-connected to the conveyor belt 31, and the four transmission shafts 38 are rotatably set at the four corners of the fixed frame 14 to support the conveyor belt 31 in a trapezoidal shape.

[0051] like Figure 1 , Figure 3 and Figure 8 As shown, the U-shaped stopper 32 is located at one end of the inner cavity of the groove 33 and is fixedly connected with two first limit columns 34, and the two first limit columns 34 are slidably connected to the conveyor belt 31. The U-shaped stopper 32 is located at one end of the inner cavity of the groove 33 and is installed with a T-shaped slider 35, and the T-shaped slider 35 is slidably connected to the conveyor belt 31. The upper end of the T-shaped slider 35 is fixedly connected with a first tension spring 36, and one end of the first tension spring 36 is fixedly connected to the conveyor belt 31.

[0052] Specifically, when the thickness of the screw rod 8 is detected, the transmission shaft 38 is driven to rotate, which in turn drives the driven wheel 37 to rotate, and at the same time drives the conveyor belt 31 to rotate. During the rotation of the conveyor belt 31, the first limiting column 34 and the T-shaped slider 35 are driven to move synchronously, and the first limiting column 34 and the T-shaped slider 35 drive the U-shaped stop block 32 to move. During the rotation of the conveyor belt 31, the T-shaped slider 35 is pulled upward by the first tension spring 36, and the T-shaped slider 35 is made to slide inside the conveyor belt 31 to push the U-shaped stop block 32 out of the groove 33. Then, during the movement of the U-shaped stop block 32 driven by the conveyor belt 31, the U-shaped stop block 32 receives the abutment screw rod 8 and transports it to the bottom of the pressing plate 48. After the U-shaped stop block 32 abuts and pushes the screw rod 8 to enter the bottom of the pressing plate 48, the thickness of the screw rod 8 is detected. If When inspecting parts with thinner thickness, after the U-shaped stop block 32 abuts and pushes the part to enter under the pressing plate 48, the U-shaped stop block 32 will fit with the pressing plate 48, and the pressing plate 48 will push the U-shaped stop block 32 to slide into the inner cavity of the groove 33. At the same time, the U-shaped stop block 32 pushes the first limit column 34 and the T-shaped slider 35 to move downward, thereby preventing the U-shaped stop block 32 from affecting the inspection of parts. After the inspection of the parts is completed, the U-shaped stop block 32 pushes the parts to slide out of the pressing plate 48, and then the first tension spring 36 pulls the T-shaped slider 35 to push the U-shaped stop block 32 to reset, thereby solving the problem that the existing laser equipment part length and thickness measuring device cannot automatically receive the parts when performing thickness inspection on the parts, and drive the parts to move to the bottom of the thickness meter for thickness inspection, resulting in low efficiency of part thickness inspection.

[0053] like Figure 1 , Figure 3 and Figure 5 As shown, the upper end surface of the support frame 41 is fixedly connected to a metering cylinder 43, a sliding hole 47 is opened on the upper end surface of the metering cylinder 43, a T-shaped sliding column 44 is slidably connected in the inner cavity of the metering cylinder 43, a metering rod 45 is fixedly connected to the upper end of the T-shaped sliding column 44, and the metering rod 45 is slidably connected to the inner cavity of the sliding hole 47, and a photoelectric encoder is arranged on the inner wall of the sliding hole 47 for real-time sensing and detection of the sliding position change of the metering rod 45.

[0054] like Figure 1 , Figure 3 and Figure 5 As shown, a spring 46 is fixedly connected to the upper end of the T-shaped sliding column 44, one end of the spring 46 is fixedly connected to the upper wall of the inner cavity of the metering cylinder 43, and the spring 46 is arranged on the outside of the metering rod 45. A metering scale is arranged on the outside of the metering rod 45, which is used to observe the position of the metering scale outside the metering rod 45 sliding out of the sliding hole 47 to calculate the thickness of the screw 8, and two second limit columns 42 are fixedly connected to the upper end surface of the pressing plate 48, and the two second limit columns 42 are slidably connected to the support frame 41 to ensure the stability of the pressing plate 48 sliding upward.

[0055] Specifically, after the U-shaped abutment block 32 is used to abut and push the screw rod 8 into the bottom of the pressing plate 48, the screw rod 8 will lift the pressing plate 48 and move upward. At the same time, the pressing plate 48 pushes the T-shaped slide column 44 to slide and move upward inside the support frame 41. During the upward movement of the T-shaped slide column 44, it will slide into the inner cavity of the metering cylinder 43. At the same time, the T-shaped slide column 44 pushes the metering rod 45 to slide and move upward in the inner cavity of the sliding hole 47. A photoelectric encoder is provided on the inner wall of the sliding hole 47. During the upward movement of the metering rod 45 pushed by the T-shaped slide column 44, the photoelectric encoder can sense the position change of the metering rod 45 and convert it into an electrical signal to output to the console. The console then processes and analyzes the signal to obtain the degree of sliding of the metering rod 45. The degree of sliding of the metering rod 45 is the thickness of the screw rod 8. When the thickness of the screw 8 does not meet the standard, an alarm reminder is issued through the console, and then the screw 8 is transported to the conveyor belt. After the tail of 31, the operator collects it to avoid it from being mixed with qualified parts. If the electronic thickness gauge such as the photoelectric encoder is damaged, the screw 8 can lift the pressing plate 48 to move upward, and at the same time, the pressing plate 48 pushes the T-shaped slide column 44 to slide upward inside the support frame 41, and then the T-shaped slide column 44 pushes the metering rod 45 to slide upward in the inner cavity of the slide hole 47. Then the operator observes the distance at which the metering scale outside the metering rod 45 slides out of the slide hole 47, and this distance is the thickness of the screw 8, thereby improving the practicality of the component thickness measuring device and solving the problem that when the existing laser equipment component length thickness measuring device performs thickness detection on the component, if the electronic thickness gauge is damaged, the electronic thickness gauge needs to be replaced or repaired before the thickness detection can be performed again, which not only causes delays in the component thickness detection link, but also affects the production efficiency of the component. Embodiment 2

[0056] like Figure 4 , Figure 6 and Figure 7 As shown, a material storage assembly 5 is provided on one side of the fixed plate 2, and the material storage assembly 5 includes a storage box 51 arranged on one side of the fixed plate 2, and the upper end of the storage box 51 is arranged in an eight-shaped shape for receiving the storage screw 8, and a sliding rod 58 is installed on one side of the storage box 51, and the sliding rod 58 is made of rubber material, which is used to guide the conveyed screw 8 into the inner cavity of the storage box 51 for collection.

[0057] Specifically, when measuring the length and thickness of laser equipment parts, the fixing plate 2 is installed at the tail end of the production line of laser equipment parts, and then the production line is used to convey the screw 8, and the upper end of the storage box 51 is set in an eight-shaped shape. During the movement of the conveying screw 8 on the production line, the screw 8 will fall into the inner cavity of the storage box 51 for collection and storage, and then during the rotation of the conveyor belt 31, the U-shaped block 32 is used to automatically collect the screw 8 in the inner cavity of the storage box 51, and drive the screw 8 to be conveyed to the bottom of the thickness measurement component 4 for thickness detection, thereby improving the efficiency of length and thickness measurement detection of laser equipment parts.

[0058] like Figure 4 , Figure 6 and Figure 7 As shown, four receiving grooves 56 are symmetrically opened on one side of the fixed plate 2, and the bottom of the inner cavity of the four receiving grooves 56 are fixedly connected to a second tension spring 57, one end of the second tension spring 57 is fixedly connected to a T-shaped slide bar 53, one end of the T-shaped slide bar 53 is fixedly installed with the storage box 51, and a push plate 52 is installed on the lower end surface of the storage box 51, and the push plate 52 is located between the fixed plates 2 and one end is set in a semicircular arc shape for guiding the sliding of the U-shaped stop block 32.

[0059] like Figure 4 , Figure 6 and Figure 7 As shown, a discharge port 55 is provided on one side of the storage box 51 between the fixed plates 2, an L-shaped shifting frame 54 is slidably connected to the interior of the lower end surface of the storage box 51, a support plate 59 is fixedly connected to one end of the L-shaped shifting frame 54, and one end of the support plate 59 is fixedly installed to the fixed plate 2, for shifting the screw 8 in the inner cavity of the storage box 51 to discharge the material.

[0060] Specifically, when measuring the length and thickness of laser equipment parts, the fixed plate 2 is installed at the tail of the laser equipment parts production line, and then the screw 8 is transported into the inner cavity of the storage box 51 for storage and collection by using the production line, and the conveyor belt 31 is started to rotate, thereby driving the U-shaped block 32 to move. After the conveyor belt 31 drives the U-shaped block 32 to move to the bottom of the storage box 51, the U-shaped block 32 will abut against the push plate 52, and the push plate 52 is located between the fixed plates 2 and has one end in a semicircular arc shape, so as to facilitate the U-shaped The stopper 32 cooperates with the circular arc to slide into one side of the push plate 52, thereby pushing the push plate 52 to drive the storage box 51 to move away from the fixed plate 2. At the same time, the U-shaped stopper 32 drives the T-shaped slider 35 and the first limit column 34 to abut against the transmission shaft 38 to prevent the U-shaped stopper 32 from sliding into the inner cavity of the groove 33 due to the weight of the storage box 51 during the process of pushing the push plate 52 by the U-shaped stopper 32. When the storage box 51 moves away from the fixed plate 2, the storage box 51 will drive the T-shaped slide bar 53 to pull the second tension spring 57 to move synchronously. At the same time, the L-shaped The toggle frame 54 slides in the inner cavity of the storage box 51, thereby pulling the screw 8 out of the inner cavity of the storage box 51. Then, after the U-shaped stop block 32 is disengaged from the push plate 52, the U-shaped stop block 32 lifts the screw 8 to move upward. At the same time, the second tension spring 57 pulls the T-shaped slide bar 53 to reset, and the T-shaped slide bar 53 drives the storage box 51 and the push plate 52 to reset. Then, the U-shaped stop block 32 pushes the screw 8 to move upward in the space formed by the conveyor belt 31 and the storage box 51, preventing the U-shaped stop block 32 from moving when pushing the screw 8 for conveying. There is no obstruction on one side of the conveyor belt 31, which causes the screw 8 to slip out of the U-shaped stop block 32, thereby solving the problem that the existing laser equipment component length and thickness measuring device is unable to automatically pick up materials and control the amount of materials picked up when detecting the thickness length of the screw. At the same time, when the screw is conveyed to the bottom of the thickness meter, it is auxiliary limited to prevent it from detaching from the material picking and conveying assembly, resulting in the screw being unable to be stably conveyed to the bottom of the thickness meter, thereby affecting the thickness detection accuracy and production efficiency of laser equipment components.

[0061] like Figures 2 to 4 As shown, a length detection groove 9 is provided on one side of the upper end surface of the base 1, and length meters 7 are installed at both ends of the inner cavity of the length detection groove 9. A material guide rack 6 is installed on one side of the fixed plate 2. The material guide rack 6 is located between the fixed plates 2 and a guide block 12 is installed. The upper end of the guide block 12 is semicircular and arranged to guide the movement of the U-shaped stop block 32. A discharge port 13 is provided at the lower part of one end surface of the material guide rack 6. The bottom of the inner cavity of the material guide rack 6 is triangular and arranged to guide the discharge of the screw 8.

[0062] Specifically, after the U-shaped stop block 32 drives the screw rod 8 to complete the thickness detection, the U-shaped stop block 32 pushes the screw rod 8 to slide out of the pressing plate 48. After the screw rod 8 slides out of the pressing plate 48, the support block 10 lifts the middle part of the conveyor belt 31 to form a thickness detection platform. At the same time, after lifting the middle part of the conveyor belt 31, the two sides of the conveyor belt 31 will be inclined at a certain angle. Then, after the screw rod 8 slides out of the pressing plate 48, it will slide forward and abut against one side of the U-shaped stop block 32. Then, when the conveyor belt 31 drives the U-shaped stop block 32 to rotate to the guide frame 6, the U-shaped stop block 32 will support the screw rod 8 to move synchronously. When the U-shaped stop block 32 moves to the guide block 12, the screw rod 8 will slide into the inner cavity of the guide frame 6. At the same time, since the upper end of the guide block 12 is semicircular The U-shaped stop block 32 is fitted with the guide block 12 to push the first limit column 34 and the T-shaped slider 35 into the inner cavity of the conveyor belt 31, and the bottom of the inner cavity of the guide frame 6 is triangularly arranged, and then when the screw 8 enters the inner cavity of the guide frame 6, it will be discharged from the discharge port 13 through the triangular guidance and fall into the inner cavity of the length detection groove 9, and then the length meter 7 is started to detect the length of the screw 8 in the inner cavity of the length detection groove 9. After the detection is completed, the operator of the screw 8 takes it out and collects it, thereby solving the problem of low production efficiency of laser equipment parts due to the inability to perform rapid measurement and detection of laser equipment parts in an automated manner when the existing length and thickness measuring device of laser equipment parts performs length and thickness detection on laser equipment parts.

[0063] A method for measuring the length and thickness of laser equipment parts is applied to a device for measuring the length and thickness of laser equipment parts, and comprises the following steps:

[0064] S1. Calibration: First, place standard parts under the thickness measurement component for calibration to ensure the accuracy of the measurement results. Then use the console to set the results of the detection calibration. When the subsequent parts exceed or fall below this standard, the console will issue an alarm to remind the operator to recycle the parts.

[0065] S2, thickness measurement detection: by installing the material storage component at the tail of the laser equipment parts production line, using the material storage component to collect the parts delivered by the production line, and then using the material collection and conveying component to automatically take the materials and convey them to the bottom of the thickness measurement component in a cycle, and the detection results are transmitted to the control console for real-time recording and storage;

[0066] S3, length measurement and detection: After the thickness detection of the parts is completed, the parts are transported to the inside of the guide rack through the material pick-up and conveying assembly, and the parts are transported into the length detection slot by the guide rack, and the length of the parts is detected by the length meter, and the detection results are transmitted to the control console for real-time recording and storage;

[0067] S4. Packaging: After the length and thickness measurement of the parts are completed, the parts that meet the length and thickness standards are collected and sent to the packaging station for packaging, while those that do not meet the length and thickness standards are recycled.

[0068] Working principle: when measuring the length and thickness of laser equipment parts, the fixed plate 2 is installed at the tail end of the laser equipment parts production line, and then the screw 8 is transported into the inner cavity of the storage box 51 for storage and collection by using the production line, and the conveyor belt 31 is started to rotate, thereby driving the U-shaped stop block 32 to move. After the conveyor belt 31 drives the U-shaped stop block 32 to move to the bottom of the storage box 51, the U-shaped stop block 32 will abut against the push plate 52, and the push plate 52 is located between the fixed plates 2 and has one end in a semicircular arc shape, so that it is convenient for the U-shaped stop block 32 to cooperate with the circular arc to slide into one side of the push plate 52, thereby pushing the push plate 52 to drive the storage box 51 to move away from the fixed plate 2. At the same time, the U-shaped stop block 32 drives the T-shaped slider 35 and the first limit column 34 to abut against the transmission shaft 38 to prevent the U-shaped stop block 32 from pushing the push plate 52. The block 32 slides into the inner cavity of the groove 33 under the weight of the storage box 51, and when the storage box 51 moves away from the fixed plate 2, the storage box 51 will drive the T-shaped slide bar 53 to pull the second tension spring 57 to move synchronously, and at the same time, the L-shaped toggle frame 54 slides in the inner cavity of the storage box 51, thereby toggling the screw rod 8 out of the inner cavity of the storage box 51, and then after the U-shaped stop block 32 is disengaged from the push plate 52, the U-shaped stop block 32 will lift the screw rod 8 to move upward, and at the same time, the second tension spring 57 pulls the T-shaped slide bar 53 to reset, and the T-shaped slide bar 53 drives the storage box 51 and the push plate 52 to reset and move, and then the U-shaped stop block 32 drives the screw rod 8 to move upward in the space formed by the conveyor belt 31 and the storage box 51, so as to prevent the U-shaped stop block 32 from sliding out of the U-shaped stop block 32 when the screw 8 is being transported.

[0069] When the thickness of the screw rod 8 is detected, the transmission shaft 38 is driven to rotate, thereby driving the driven wheel 37 to rotate, and at the same time driving the conveyor belt 31 to rotate. During the rotation of the conveyor belt 31, the first limiting column 34 and the T-shaped slider 35 are driven to move synchronously, and the first limiting column 34 and the T-shaped slider 35 drive the U-shaped stop block 32 to move. During the rotation of the conveyor belt 31, the T-shaped slider 35 is pulled upward by the first tension spring 36, and the T-shaped slider 35 is made to slide inside the conveyor belt 31 to push the U-shaped stop block 32 out of the groove 33. Then, during the movement of the U-shaped stop block 32 driven by the conveyor belt 31, the U-shaped stop block 32 receives the contact screw 8 and is input to the bottom of the pressing plate 48. After the U-shaped stopper 32 abuts against and pushes the screw rod 8 to enter under the pressing plate 48, the thickness of the screw rod 8 is then detected. If a thinner component is to be detected, the U-shaped stopper 32 abuts against and pushes the component to enter under the pressing plate 48, and the U-shaped stopper 32 will fit with the pressing plate 48, and the pressing plate 48 will push the U-shaped stopper 32 to slide into the inner cavity of the groove 33, and at the same time, the U-shaped stopper 32 pushes the first limit column 34 and the T-shaped slider 35 to move downward, thereby preventing the U-shaped stopper 32 from affecting the detection of the component. After the detection of the component is completed, the U-shaped stopper 32 pushes the component to slide out of the pressing plate 48, and then the first tension spring 36 pulls the T-shaped slider 35 to push the U-shaped stopper 32 to reset;

[0070] After the U-shaped stop block 32 drives the screw rod 8 to complete the thickness detection, the U-shaped stop block 32 pushes the screw rod 8 to slide out of the pressing plate 48. After the screw rod 8 slides out of the pressing plate 48, the support block 10 lifts the middle part of the conveyor belt 31 to form a thickness detection platform. At the same time, after lifting the middle part of the conveyor belt 31, the two sides of the conveyor belt 31 will be inclined at a certain angle. Then, after the screw rod 8 slides out of the pressing plate 48, it will slide forward and abut against one side of the U-shaped stop block 32. Then, when the conveyor belt 31 drives the U-shaped stop block 32 to rotate to the guide frame 6, the U-shaped stop block 32 will support the screw rod 8 to move synchronously. When it moves to the guide block 12, the screw 8 will slide into the inner cavity of the guide frame 6. At the same time, since the upper end of the guide block 12 is arranged in a semicircular arc shape, the U-shaped stop block 32 is fitted with the guide block 12 to push the first limit column 34 and the T-shaped slider 35 to slide into the inner cavity of the conveyor belt 31. The bottom of the inner cavity of the guide frame 6 is arranged in a triangular shape, and then when the screw 8 enters the inner cavity of the guide frame 6, it will be discharged from the discharge port 13 through the triangular guidance and fall into the inner cavity of the length detection groove 9. Then the length meter 7 is started to detect the length of the screw 8 in the inner cavity of the length detection groove 9. After the detection is completed, the operator of the screw 8 will take it out and collect it.
