DETAILED DESCRIPTION

[0037] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0038] like Figures 1 to 5 As shown, an automatic detection device of the utility model comprises:

[0039] The first conveyor belt 1;

[0040] A transfer unit 2, which has a pneumatic clamp 3 movably arranged above the first conveyor belt 1, and is used to transport the workpiece;

[0041] A visual inspection unit 4, which is arranged on the side of the first conveyor belt 1 and is used for visual inspection of the workpiece;

[0042] A pneumatic detection unit 5 is arranged on the side of the visual detection unit 4. The pneumatic detection unit 5 has a movable clamping block 6, a clamping piece 7 and a detection rod 8. The clamping block 6, the clamping piece 7 and the detection rod 8 are arranged from top to bottom in the pneumatic detection unit 5, and the clamping block 6 is movably abutted against the upper part of the workpiece to fix it in the outer diameter direction of the workpiece, the clamping piece 7 is movably abutted against the middle part of the workpiece to fix it in the height direction of the workpiece, and the detection rod 8 is movably inserted at the bottom of the workpiece to perform pneumatic detection on the workpiece;

[0043] The detection rod 8 is preferably a pneumatic measuring instrument, which is a precision measuring instrument that uses compressed air as a measuring medium and performs non-contact precision measurement of various length dimensions based on the principles of fluid statics and fluid dynamics;

[0044] A second conveyor belt 9 is arranged at the side of the pneumatic inspection unit 5 and is used to receive the workpieces that have passed the inspection and transport them to a preset position;

[0045] The third conveyor belt 10 is arranged at the side of the second conveyor belt 9 and is used to receive unqualified workpieces and transport them to a preset position.

[0046] During operation, the first conveyor belt 1 transports the workpiece to be inspected to a preset grabbing position. Driven by the transfer unit 2, the pneumatic clamp 3 clamps the workpiece to be inspected on the first conveyor belt 1 and transports it to the location of the visual inspection unit 4 along a preset path. The visual inspection unit 4 accurately inspects various sizes of the workpiece through visual inspection. After the inspection is completed, the pneumatic clamp 3 continues to transport the workpiece to the location of the pneumatic inspection unit 5. After arriving, the clamp 7 first clamps the middle of the workpiece, and then the clamping block 6 is movably clamped with the upper part of the workpiece to form a stable clamping connection, ensuring that the workpiece is accurately positioned and fixed in the pneumatic inspection unit 5. Finally, the inspection rod 8 is movably inserted at the bottom of the workpiece to start the inspection of the workpiece. Pneumatic detection operation is carried out to perform non-contact precision measurement. After all detection procedures are completed, the clamping member 7, the clamping block 6 and the detection rod 8 are separated from the workpiece one by one. Next, the pneumatic clamp 3 accurately transports the qualified workpiece to the second conveyor belt 9 according to the detection result. The second conveyor belt 9 transports the qualified workpiece to the preset position. The unqualified workpiece will be transferred to the third conveyor belt 10. The third conveyor belt will transport the unqualified workpiece to the preset position, and the detection work is completed. This automatic detection method can not only greatly reduce labor costs and significantly improve detection efficiency, but also fully meet the continuously growing production demand and the continuously improving quality standards in a large-scale production environment.

[0047] More specifically, the transport unit 2 includes:

[0048] A support seat 11, which is arranged on the side of the first conveyor belt 1;

[0049] A first driving member 12, which is horizontally arranged on the support base 11, and the first driving member 12 can be a motor or a cylinder;

[0050] A second driving member 13, which is vertically arranged at the output end of the first driving member 12, and the output end of the second driving member 13 is connected to a plurality of pneumatic clamps 3, and the second driving member 13 can be a motor or a cylinder;

[0051] When the first conveyor belt 1 transports the workpiece to be inspected to a preset position, the pneumatic clamp 3 is located directly above the workpiece. Then, the second drive member 13 is started, driving the pneumatic clamp 3 to descend to a preset clamping position, and the pneumatic clamp 3 clamps the workpiece. Subsequently, the second drive member 13 is driven in reverse, driving the pneumatic clamp 3 to rise, so that the clamped workpiece leaves the first conveyor belt 1 and rises synchronously with the pneumatic clamp 3. At the same time, the first drive member 12 is started, driving the second drive member 13 to move horizontally, driving the pneumatic clamp 3 to move horizontally, thereby realizing directional transportation of the clamped workpiece.

[0052] More specifically, the visual inspection unit includes:

[0053] A first supporting platform 14 is arranged on the side of the first conveyor belt 1, and a rotating block 15 is arranged on the first supporting platform 14;

[0054] A first detection member 16, which is disposed on the side of the first supporting platform 14 and is used for visually detecting the outer diameter of the workpiece;

[0055] A second detection member 17, which is disposed above the first supporting platform 14 and is used for visually detecting the height of the workpiece;

[0056] A third driving member 18, which is disposed in the first supporting platform 14 and the rotating block 15 is connected to the output end of the third driving member 18, and the third driving member 18 is used to drive the rotating block 15 to rotate. The third driving member 18 is preferably a motor;

[0057] The rotating block 15 can drive the workpiece to rotate because the pneumatic clamp 3 transports the workpiece thereon, so that the first detection member 16 can detect the outer diameter of the workpiece.

[0058] When the transfer unit 2 transports the workpiece to the rotating block 15, at this moment, the third driving member 18 responds immediately, driving the rotating block 15 connected to its output end to start to rotate smoothly. Since the workpiece has been stably placed on the rotating block 15, it will rotate synchronously with the rotating block 15 to form a continuously changing posture for comprehensive visual inspection. At the same time, the first detection member 16 begins to perform visual inspection on the workpiece. As the workpiece continues to rotate on the rotating block 15, the first detection member 16 can capture the peripheral image data of the workpiece from different perspectives, thereby accurately measuring the outer diameter of the workpiece. In the same inspection cycle, the second detection member 17 also simultaneously carries out visual measurement of the height of the workpiece. The second detection member 17 is arranged above the first supporting platform 14 and has the ability to look down on the workpiece. Even if the workpiece is in a rotating state, the second detection member 17 can continue to focus on the top of the workpiece and use a visual inspection algorithm to accurately determine the height of the workpiece. The first detection member 16 and the second detection member 17 are preferably visual inspection equipment.

[0059] More specifically, the pneumatic detection unit 5 includes:

[0060] The second support platform 19 is arranged on the side of the first support platform 14. A through hole is arranged on the second support platform 19. The diameter of the through hole is smaller than the diameter of the bottom of the workpiece and larger than the diameter of the detection rod 8, so as to ensure that the detection rod 8 can be flexibly inserted at the bottom of the workpiece for detection;

[0061] The fourth driving member 20 is arranged on one side of the second supporting platform 19, and the clamping block 6 is connected to the output end of the fourth driving member 20. The fourth driving member 20 can be a motor or a cylinder;

[0062] A fifth driving member 21 is arranged on a side of the second supporting platform 19 away from the fourth driving member 20 and the clamping member 7 is connected to an output end of the fifth driving member 21. The fifth driving member 21 may be a motor or a cylinder;

[0063] A sixth driving member 22, which is disposed on the second supporting platform 19 and below the through hole, the detection rod 8 is connected to the output end of the sixth driving member 22, and the sixth driving member 22 may be a motor or a cylinder;

[0064] When the transfer unit 2 transports the workpiece that has completed visual inspection to the second support platform 19 and is located directly above the perforation, first, the fifth drive member 21 drives the clamping member 7 to move, so that it clamps the middle part of the workpiece to ensure that the workpiece remains stable during the inspection process; then, the fourth drive member 20 is started, driving the clamping block 6 to move toward the clamped workpiece until a stable active clamping is formed with the upper part of the workpiece, further enhancing the positioning accuracy and stability of the workpiece; then, the sixth drive member 22 drives the detection rod 8 to rise, so that it passes through the perforation and is accurately inserted into the detection position set at the bottom of the workpiece. When the detection rod 8 contacts the workpiece, pneumatic inspection of the workpiece is started, and the pneumatic elements inside the detection rod 8 sense the size, shape or other relevant parameters of the bottom of the workpiece; the entire pneumatic inspection unit 5 achieves precise positioning, effective fixation and targeted pneumatic inspection of the workpiece through the coordinated work of various drives, ensuring the automation, efficiency and accuracy of the inspection process.

[0065] In order to ensure that the workpiece can be accurately and smoothly transported to the preset grabbing position on the first conveyor belt 1, a guide groove 23 is also provided above the conveyor belt. The first conveyor belt 1 drives the workpiece to move along the guide groove 23. The guide groove 23 is used to provide guidance for the movement of the workpiece on the first conveyor belt 1 to ensure that it moves along a predetermined trajectory, thereby avoiding inaccurate positioning problems caused by the offset of the workpiece during the transmission process.

[0066] After all the inspection procedures are completed, the transfer unit 2 performs corresponding sorting operations according to the inspection results obtained. For workpieces with qualified inspection results, the transfer unit 2 transports them from the second support platform 19 to the second conveyor belt 9. The second conveyor belt 9 is dedicated to receiving and transporting these qualified workpieces to the preset position; on the contrary, for workpieces with unqualified inspection results, the transfer unit 2 will transport them to the third conveyor belt 10. The third conveyor belt 10 is specifically responsible for transporting these unqualified workpieces to the preset position.

[0067] In order to collect qualified workpieces that have passed the inspection, a first collecting bin 24 is provided on the side of the second conveyor belt 9. A first receiving portion 25 is provided on the first collecting bin 24, which is located below the second conveyor belt 9. When the workpiece that has completed the inspection on the second conveyor belt 9 and is determined to be qualified arrives at the end, it will naturally slide from the first receiving portion 25 into the first collecting bin 24, thereby realizing the effective collection of workpieces.

[0068] Similarly, in order to centrally process unqualified workpieces that fail the inspection, a second collection bin 26 is also provided on the side of the third conveyor belt 10. The second collection bin 26 is provided with a second receiving portion 27, which is located below the third conveyor belt 10. When the unqualified workpieces on the third conveyor belt 10 are transported to the end point, they will flow into the second collection bin 26 through the second receiving portion 27, so that the unqualified workpieces can be clearly distinguished from the qualified workpieces and properly stored.

[0069] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0070] In addition, in the present invention, the descriptions of "first", "second", "one", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features.
