Description

Technical Field

[0001] This utility model relates to a laser inspection device, specifically a laser inspection device for saw blade heads. Background Technology

[0002] During the production and processing, the base body and the saw head are often connected by methods such as inlaying, brazing, and laser welding. However, since the welding process is not absolutely ideal, in order to ensure the service life of the saw blade, it is necessary to use a laser testing device to test the connection strength between the saw head and the base body.

[0003] Chinese patent application CN115406380A discloses a device and method for detecting the welding angle of a carbide saw blade tip, which includes a conveyor belt, a feeding robot, a conveying device, a driving device, a clamping device, a detection device, a clamping robot, and a feeding conveyor belt.

[0004] In the aforementioned prior art, the saw blade is positioned by clamping the central through hole with the positioning block, and the saw blade is pushed upward by the pusher and the return spring to separate the saw blade from the positioning block. During the separation process, due to the uncontrollable elastic force of the return spring and the static friction between the positioning block and the saw blade, the saw blade may jump or even fall off after being pushed away during actual operation, affecting the normal transfer and detection of the saw blade. Utility Model Content

[0005] The purpose of this invention is to provide a laser detection device for saw blade heads, which solves the problems of saw blade jumping, deviation, or even saw blade falling off in the existing technology.

Each positioning block surrounds each other to form a cylindrical structure that can cooperate with the central through hole of the saw blade. Each positioning block can reciprocate towards the circumferential center. When the gripping disc moves down and contacts the outer wall of each positioning block, each positioning block moves towards the circumferential center until the central through hole of the saw blade separates from the outer wall of the positioning block.

[0007] As a further preferred technical solution of this utility model, the bottom surface of the gripping disc is provided with a plurality of suction cups for gripping the saw blade, and when the suction cups grip the saw blade, the laser detection head is flush with the cutting edge of the saw blade.

[0020] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0021] like Figure 1-2 As shown, a laser inspection device for saw blade tips includes a turntable 1 and a fixed frame 4 located adjacent to the turntable 1. The top surface of the turntable 1 has several positioning discs 2 evenly distributed around a rotation center for positioning the saw blade. A servo motor is located below the turntable, and a transmission shaft connected to the servo motor is located at the bottom of the turntable. The servo motor can drive the turntable to rotate via the transmission shaft, adjusting the position of each positioning disc on the turntable to achieve different processes for the saw blade when each positioning disc is in a different position. The fixed frame 4 has a gripping disc 3 above one of the positioning discs 2, which can be raised, lowered, and rotated, and a laser inspection head 31 located adjacent to the gripping disc 3 and raised and lowered synchronously with the gripping disc 3. The laser inspection head is existing technology and will not be described in detail here. When the gripping disc grips the saw blade, the laser inspection head can be aligned with the outer edge of the saw blade. When the gripping disc drives the saw blade to rotate, the laser inspection head can begin inspection, comprehensively inspecting the outer edge of the rotating saw blade. A ring of [something] is located around the center of the top surface of the positioning disc 2. Multiple circumferentially evenly distributed positioning blocks 21 are arranged together to form a cylindrical structure that can mate with the central through hole of the saw blade. Each positioning block 21 can reciprocate towards the circumferential center. When the gripper 3 moves down and contacts the outer wall of each positioning block 21, each positioning block 21 moves towards the circumferential center until the central through hole of the saw blade separates from the outer wall of the positioning block 21. In the normal state, the circumference of the cylindrical structure formed by the positioning blocks is consistent with the central through hole of the saw blade. The central through hole of the saw blade can fit perfectly on the side wall of each positioning block to achieve positioning of the saw blade. When the gripper grabs the saw blade, each positioning block moves synchronously towards the enclosing center, so that the outer wall of each positioning block separates from the edge of the central through hole of the saw blade. This can avoid static friction between the positioning block and the saw blade during separation, ensuring that the saw blade can smoothly and stably detach from the positioning plate for laser detection. This can effectively prevent the saw blade from jumping, shifting, or falling when it detaches from the positioning plate, ensuring the normal transfer and detection of the saw blade.

[0022] like Figure 1 and 3As shown, the bottom surface of the gripper 3 is equipped with multiple suction cups 32 for gripping the saw blade. When the suction cups 32 grip the saw blade, the laser detection head 31 is flush with the cutting edge of the saw blade. The aforementioned suction cups are existing technology and will not be described in detail here. When the gripper moves down close to the saw blade until the suction cups abut against the end face of the saw blade, the suction cups automatically adhere to the saw blade. When the gripper moves up, the saw blade is firmly adhered to the suction cups and moves up with the gripper. The laser detection head is always aligned with the outer edge of the saw blade. The top of the fixing frame 4 is equipped with a crossbeam 41. A drive cylinder 42 is provided on the top surface of the outer end. The cylinder rod of the drive cylinder 42 passes downward through the crossbeam 41 and is connected to the rotary motor 44. The output shaft of the rotary motor 44 extends downward and is connected to the top surface of the gripper 3. The drive cylinder can drive the gripper to move up and down. When the gripper grabs the saw blade, the drive cylinder drives the gripper to move upward with the saw blade. The rotary motor then starts and drives the gripper to rotate with the saw blade. The laser detection head performs a comprehensive inspection of the outer edge of the rotating saw blade, realizing automated laser inspection of the saw blade.

[0023] like Figure 2 , 4 As shown in Figure 5, each positioning block 21 has a conical surface 211 on its top sidewall, and a sleeve 33 is provided in the middle of the bottom surface of the gripper 3. The bottom of the sleeve 33 has a conical hole 331 with a taper smaller than that of the conical surface 211 of each positioning block 21. As the gripper moves down and approaches the saw blade, the sleeve gradually contacts the conical surface at the top of the top block. Since the taper of the conical hole is smaller than that of the conical surface, when the conical hole fits onto the conical surface and gradually moves down, each positioning block is squeezed and pushed towards the center of the enclosure to shrink, causing the outer wall of the positioning block to separate from the edge of the central through hole of the saw blade. The gripper can then use the suction cup to attract the saw blade and drive the saw blade to rise smoothly. A fixing block 22 is provided at the center of the enclosure of each positioning block 21. The sidewall of the fixing block 22 has multiple first receiving grooves 221 corresponding to each positioning block 21. The inner side of the positioning block 21 has a first receiving groove 221 corresponding to the first receiving groove 221. Two receiving grooves 212, a first telescopic spring 23 is provided between the first receiving groove 221 and the second receiving groove 212. When the saw blade is inserted into the outer wall of a positioning block, the first telescopic spring acts on the positioning block under the support of the fixed block, causing the positioning block to move outward and squeeze the edge of the central through hole of the saw blade, thus achieving reliable positioning of the saw blade. When the first telescopic spring retracts, the positioning block can be separated from the saw blade. The top surface of the positioning disk 2 is provided with a guide rail 24 arranged along the moving direction of each positioning block 21 in the middle corresponding to the bottom of each positioning block 21. Each positioning block 21 has a sliding groove 213 at the bottom that cooperates with the guide rail 24. When the positioning block moves, the positioning block moves along the guide rail through the sliding groove at the bottom, ensuring the accurate orientation of the positioning block and enhancing the precision of the positioning block movement, so as to ensure reliable positioning and separation between the positioning block and the saw blade.

[0024] like Figure 2 and 4As shown, each positioning block 21 has a support block 214 on its outer wall for supporting the edge of the central through hole of the saw blade. The top edge of the positioning disk 2 has an annular support block 25 for supporting the outer circumference of the saw blade. The support blocks can support the edge of the central through hole of the saw blade, and the annular support blocks can support the outer circumference of the saw blade, achieving double-edge support for the saw blade. This ensures the stability of the saw blade support and prevents the saw blade from being placed unevenly, which could affect the gripping of the gripper or even damage the saw blade. The bottom surface of the annular support block 25 has several third receiving grooves 251. The upper wall of each third receiving groove 251 has a guide post 252 that passes downward through the positioning disk 2, guiding... The bottom end of the column 252 is provided with a limiting block 253 that can abut against the bottom surface of the positioning plate 2. The third receiving groove 251 is provided with a second telescopic spring 254 that is connected to the top surface of the positioning plate 2. The annular support block is movably connected to the positioning plate through the guide column and the limiting block to prevent the annular support block from shifting or detaching from the positioning plate. At the same time, through the action of the second telescopic spring, it provides floating support for the saw blade, ensuring that when the saw blade is inserted into the positioning block, the floating support of the annular support block can adapt to the thickness and height of the saw blade and provide stable support for the saw blade. At the same time, when the saw blade is separated from the positioning block, it applies a certain upward force to the saw blade to assist the saw blade to be quickly adsorbed by the suction cup and improve the gripping efficiency of the saw blade.

[0025] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
