Description

Technical Field

[0001] This invention relates to a PCD turning tool quality inspection device before it leaves the factory and its usage method. Background Technology

[0002] my country produces a large volume of PCD turning tools, making quality inspection crucial for enterprises. Currently, quality inspection of PCD turning tools mainly relies on manual visual inspection and simple manual measurement. This method is inefficient, has inconsistent accuracy, and cannot meet the needs of mass production.

[0003] To improve inspection efficiency, many companies have begun using robotic arms and conveyor belts to automate the feeding of PCD cutting tools, and have equipped them with mechanical probes and laser rangefinders for automated inspection. However, these automated devices can only perform simple dimensional inspections and cannot inspect complex surfaces or different orientations; flipping still requires manual operation. Furthermore, existing equipment cannot analyze and judge the inspection results, and defective products must be manually removed by operators, which is prone to human error.

[0004] Therefore, there is an urgent need to develop a new type of inspection device that can automatically flip PCD cutting tools for inspection and automatically screen and remove defective products based on the inspection results to overcome the above problems. Summary of the Invention

[0041] To address the problems of low efficiency and accuracy in existing testing methods, this invention provides a pre-shipment quality inspection device for PCD turning tools and its usage method. The technical solution of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described invention is only a part of this invention, not all of it. All other inventions obtained by those skilled in the art based on this invention without inventive effort are within the scope of protection of this invention.

[0042] Please see Figure 1-5 This invention provides a pre-shipment quality inspection device for PCD turning tools, comprising:

[0043] A symmetrically arranged strip-shaped support frame 1, with a chain conveyor mechanism provided on the opposite side of the support frame 1;

[0044] The clamping mechanism for holding PCD turning tools includes a chain conveying mechanism 2, and the clamping mechanism is disposed on the top surface of the chain plate 2 to complete the action of driving the clamping mechanism to move.

[0045] The support frame 1 is provided with a gear rack 3, a vision detector 4 and an ejection mechanism arranged sequentially on the opposite side in the conveying direction of the chain conveyor mechanism. A pair of gear racks 3, a vision detector 4 and an ejection mechanism constitute a detection rejection group. N groups of detection rejection groups are provided on the support frame 1.

[0046] The clamping mechanism includes symmetrically arranged clamping rods 5 that can move relative to or towards each other. A gear block 6 is provided at the opposite end of the clamping rods 5. The gear rack 3 is symmetrically arranged on the opposite surface of the support frame 1 and drives the gear block 6 to rotate by meshing with it.

[0047] Furthermore, the chain conveyor mechanism also includes:

[0048] Two traction chains 7 are disposed on opposite surfaces of the support frame 1;

[0049] Two drive rods 8 connecting the traction chain 7;

[0050] And a motor 9 mounted on the support frame 1, wherein the power output end of the motor 9 is connected to one of the transmission rods 8;

[0051] The two traction chains 7 are connected by the transmission rod 8 and driven by the motor 9; by starting the motor 9, the motor 9 can drive the transmission rod 8, traction chains 7 and chain plates 2 to move.

[0052] Furthermore, the clamping mechanism also includes:

[0053] Two support blocks 10 are disposed on the outer periphery of the clamping rod 5;

[0054] A pulling block 11 is provided between the two support blocks 10. One end of the pulling block 11 is provided on the support block 10 away from the gear block 6, and the other end of the pulling block 11 is provided on the outer periphery of the clamping rod 5.

[0055] The clamping head 12 is set on the opposite surface of the two clamping blocks; when installing the PCD turning tool, the length of the PCD turning tool itself determines that the two clamping rods 5 will move towards each other, thereby pulling the pulling block 11. Under the action of the elastic force of the pulling block 11, the clamping head 12 squeezes the PCD turning tool and thus completes the clamping of the PCD turning tool.

[0056] Furthermore, the launching mechanism includes:

[0057] The T-shaped groove 13 is set on the top surface of the chain plate 2;

[0058] A lifting plate 14 is provided on the slide 13, and the support block 10 is provided on the lifting plate 14;

[0059] The push rod 15 is disposed on the support frame 1, and the push rod 15 and one of the gear racks 3 are on the same plane;

[0060] The power output end of the push rod 15 is provided with an extension rod 16 that matches the shape of the slide groove 13, which is used to insert into the slide groove 13 to complete the action of pushing the lifting plate 14. The push rod 15 can be pneumatic or electric, and its main purpose is to push the extension rod 16 to move. When the extension rod 16 is inserted into the slide groove 13, the movement path of the extension rod 16 is restricted by the action of the slide groove 13. Moreover, since the contact area between the extension rod 16 and the lifting plate 14 is large, it can be pushed out more stably.

[0061] Furthermore, spherical elastic blocks 17 are symmetrically arranged on the contact surfaces of the lifting plate 14 and the groove wall of the slide 13, and a fixing groove 18 is provided on the groove wall of the slide 13 at a position corresponding to the spherical elastic blocks 17; the spherical elastic blocks 17 are inserted into the fixing groove 18 to position the lifting plate 14, thereby making its installation and operation more stable, and the elastic force of the spherical elastic blocks 17 is used to deform the spherical elastic blocks 17 when pushed by a large external force, thereby detaching them from the fixing groove 18.

[0062] Furthermore, a pair of gear racks 3 can drive the gear block 6 to rotate M°, and N groups of detection and rejection groups, where N = 360° / M°, are used. If there is a decimal, it is rounded up; if it is an integer, it is rounded up. In this way, the PCD cutting tool is detected at least 360°, making the detection more thorough.

[0063] Furthermore, the clamping head 12 is made of an elastic material and is used to wrap the PCD turning tool holder during compression; thus, during compression, the clamping head 12 at the contact position with the PCD turning tool will deform to fix the PCD turning tool.

[0064] Furthermore, the support block 10 and the pulling block 11 are rotatably connected to each other; in this way, when the clamping rod 5 rotates, it can drive the pulling block 11 to rotate, so as not to affect the normal pulling force of the pulling block 11.

[0065] Furthermore, the motor 9, vision detector 4, and push rod 15 are all controlled by a PLC controller; the PLC controller makes operation more convenient.

[0066] A method for using a PCD turning tool pre-shipment quality inspection device includes the following steps:

[0067] Step A, Numbering: Along the conveying direction of the chain conveyor, number the visual detectors 4 and push rods 15 in each rejection group in sequence;

[0068] Step B, Comparison Data Upload: Based on the rotation angle of the gear block 6 driven by the gear rack 3, take pictures of the high-quality PCD turning tool and upload the collected images to each vision detector 4 in sequence;

[0069] Step C, Loading: According to the PCD cutting tool status in the first captured image, place the PCD cutting tool to be inspected on the opposite surfaces of the two clamping heads 12, and use the elastic force of the pulling block 11 to clamp the PCD cutting tool.

[0070] Step D, Detection: Start motor 9. Motor 9 drives transmission rod 8, traction chain 7 and chain plate 2 to move, thereby driving clamping rod 5 and PCD cutting tool to rotate; when PCD cutting tool passes vision detector 4, stop motor 9 to allow vision detector 4 to detect.

[0071] Step E, rejection: If the visual detector 4 does not detect the defect, the motor 9 continues to work; if the defect is detected, the motor 9 drives the chain plate 2 to move to the extension rod 16 of the push rod 15 and stops, and starts the push rod 15 and the extension rod 16 to push out the lifting plate 14 of the defective PCD cutting tool for rejection.

[0072] Step F: Repeat the above operation until all vision detectors 4 have completed the inspection of the PCD cutting tool. Then, remove the qualified product manually or with a robotic arm. After replacing the missing support plate 14, the equipment can continue to be used.

[0073] The present invention provides a pre-shipment quality inspection device for PCD turning tools and its method of use, which has the following advantages:

[0074] 1. This invention achieves automatic flipping and inspection of PCD cutting tools by means of the cooperation between the gear rack 3 and the gear block 6, thereby improving the degree of automation of the inspection.

[0075] 2. This invention utilizes multiple sets of detection and rejection groups to detect different areas of the PCD cutting tool, thereby reducing blind spots and improving detection accuracy.

[0076] 3. The present invention is equipped with a sliding groove, a lifting plate, an extension rod and other ejection mechanisms, which realizes the automatic removal of defective PCD cutting tools when defects are detected, without the need for manual operation;

[0077] In summary, this device achieves automated, intelligent, efficient, and low-cost PCD turning tool quality inspection, ensuring product quality and possessing significant economic benefits and application value.
