Description

Technical Field

[0001] This invention relates to the field of billiard cue testing technology, specifically to a device for detecting internal defects in billiard cue materials. Background Technology

[0002] A billiard cue is a tool used in billiards, typically consisting of four core parts: the grip, the shaft, the joint, and the cue head. Some high-end cues also feature auxiliary structures such as a weighting system and a cushioning device. To ensure the quality of billiard cues, defect detection is necessary.

[0003] In related technologies, such as a billiard cue with announcement number CN102698428B, a hollow front section device is provided with a first end and a second end. The front section device has a cavity that extends through the entire length of the front section device between the first end and the second end. A carrier for mounting the front section device includes a middle section that is received within the cavity. The first end of the middle section is configured to connect against the first end of the front section device, and the second end has a threaded area that extends beyond the second end of the front section device and connects with other cue structures provided at the second end of the front section device to form the cue.

[0004] During the production of the aforementioned billiard cues, the internal structure of the cue needs to be inspected to observe whether there are any abnormalities such as cracks in the internal threads and materials. Workers usually use spotlights to illuminate the inside for inspection, which requires a long period of visual observation and is therefore inefficient. Summary of the Invention

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1: like Figures 1-8 As shown, this embodiment of the invention provides a device for detecting internal defects in billiard cue materials, comprising: refer to Figure 1 , Figure 2 The frame assembly 1 includes a drop hole 102 for providing support force; the frame assembly 1 includes a main frame plate 101, and a support leg 103 is fixedly connected to the lower part of the main frame plate 101. The main frame plate 101 can provide a blocking effect for the workpiece 7 inserted into the placement hole 204 to prevent the workpiece 7 from falling. When the workpiece 7 moves to the drop hole 102, the workpiece 7 can fall under the action of gravity, realizing the function of automatic material discharge.

[0022] refer to Figure 1 , Figure 3Multi-station component 2 is located in the middle of frame component 1 and is used to change the position of workpiece 7. Multi-station component 2 includes a rotary motor 201, the output end of rotary motor 201 is fixedly connected to a drive plate 203, a station base 202 is fixedly connected to the drive plate 203, and the station base 202 is evenly provided with placement holes 204 around its circumference. Rotary motor 201 is fixedly installed on main frame plate 101, and the output end of rotary motor 201 passes through main frame plate 101. When multiple workstations change, the rotary motor 201 operates under the control of the external power supply and controller, driving the drive plate 203 and the workstation base 202 to rotate. The number of workstation bases 202 can be selected as three, which are used to place workpiece 7, inspect workpiece 7, and discharge workpiece 7 respectively. The lower end of workpiece 7 can be inserted into the placement hole 204, thereby realizing the mutual change of placement, inspection and discharge positions. In order to ensure that workpiece 7 tilts, the workstation base 202 should have a certain thickness, such as five centimeters. Workpiece 7 is a billiard cue.

[0023] refer to Figure 1 , Figure 4 The lifting assembly 3 is located outside the multi-station assembly 2 and is used to provide lifting function. The lifting assembly 3 includes a lifting push rod 301, the output end of which is fixedly connected to a lifting plate 302, and a support slide rail 303 is fixedly connected to the lifting plate 302. The lifting push rod 301 is fixedly installed on the main frame plate 101, and the telescopic end of the lifting push rod 301 passes through the main frame plate 101 and is in sliding fit with each other. During lifting operations, the lifting push rod 301 operates under the control of the external power supply and controller, driving the lifting plate 302 and the support slide rail 303 to rise or fall. In the rising state, the clamping component 4 will not affect the normal rotation of the multi-station component 2; in the falling state, the clamping component 4 can provide clamping force for multiple workpieces 7, ensuring the stability of subsequent inspection.

[0024] refer to Figure 1 , Figure 5 The clamping component 4 is mounted on the lifting component 3 and is used to provide clamping function. The clamping component 4 includes a sliding sleeve 401, a locking screw 402 threaded on the sliding sleeve 401, an outer frame 403 fixedly connected to the sliding sleeve 401, an elongated hole 404 evenly provided around the circumference of the outer frame 403, an inner support ring 405 fixedly connected to the middle of the outer frame 403, and an annular airbag 406 fixedly connected to the inner support ring 405. The annular airbag 406 is interconnected with an external air source. The sliding sleeve 401 is slidably engaged with the support slide rail 303. During clamping operations, an external air source injects gas into the annular airbag 406, causing the annular airbag 406 to expand outward, providing a clamping force from the center outward on the workpiece 7, thus holding the upper end of the workpiece 7 in place. Simultaneously, when the position of the sliding sleeve 401 needs to be adjusted, the locking screw 402 can be turned to change the position of the sliding sleeve 401. Once the position is changed, the locking screw 402 can be tightened again to achieve the adjustment function, thus providing a suitable detection height for the detection component 5.

[0025] refer to Figure 1 , Figure 6 The detection component 5 is located on top of the lifting component 3 and is used to capture internal images of the workpiece 7. The detection component 5 includes a detection frame 501, on which a servo motor 502 is fixedly mounted. The output end of the servo motor 502 is fixedly connected to a rotating arm 503. A cylinder 504 is fixedly mounted on the rotating arm 503. The output end of the cylinder 504 is fixedly connected to a multi-directional imaging component 505. The detection frame 501 is fixedly mounted on a sliding sleeve 401. During the inspection operation, the servo motor 502 works under the action of the external power supply and controller, driving the rotating arm 503 to rotate, so that the multi-angle imaging piece 505 is located directly above the elongated hole 404. Then, under the action of the external air source and controller, the cylinder 504 drives the multi-angle imaging piece 505 to penetrate into the interior of the workpiece 7.

[0026] refer to Figure 1 , Figure 7 , Figure 8 The multi-angle shooting component 505 includes a connecting base 5051, a probe 5053 is fixedly connected to the lower part of the connecting base 5051, an outer ring camera 5054 is fixedly installed on the side of the probe 5053, a bottom camera 5055 is fixedly connected to the bottom of the probe 5053, and a cone-shaped light 5052 is fixedly installed on the lower part of the connecting base 5051. During multi-angle shooting, the cone-shaped light 5052 can generate downward-sloping light to illuminate the interior of the workpiece 7, the outer ring camera 5054 can capture images in four directions: front, back, left, and right; the bottom camera 5055 is used to capture images of the bottom, ensuring that multiple positions of the billiard cue workpiece 7 can be observed.

[0027] refer to Figure 1 , Figure 7 Control component 6 is mounted on frame component 1 and is used to control and display detection images and results. Control component 6 includes mounting column 602, and display controller 601 is fixedly mounted on the top of mounting column 602. Mounting column 602 is fixedly connected to main frame plate 101. The display controller 601 is an integration of a display, a controller, and a computer. The display is used to show the results, the controller is used to provide control commands, and the computer is used to compare and process the captured images.

[0028] Working principle: When the workpiece 7 is placed in the placement hole 204, the rotary motor 201 works, driving the drive plate 203 and the workstation 202 to rotate, and the workstation 202 containing the workpiece 7 is rotated to the position directly below the clamping assembly 4. When the lifting push rod 301 is working, it drives the lifting plate 302 and the support slide rail 303 to descend. The external air source injects gas into the ring air bag 406, and the ring air bag 406 expands outward, which can provide a clamping force from the center to the outside of the workpiece 7, and can clamp the upper end of the workpiece 7. Servo motor 502 works, driving rotating arm 503 to rotate, so that multi-angle imaging component 505 is positioned directly above elongated hole 404. Then, under the action of external air source and controller, cylinder 504 drives multi-angle imaging component 505 to penetrate into the interior of workpiece 7. The cone-shaped light 5052 can produce downward-sloping light to illuminate the interior of the workpiece 7; the outer ring camera 5054 can capture images in four directions: front, back, left, and right; the bottom camera 5055 is used to capture images from the bottom, ensuring that multiple positions of the billiard cue workpiece 7 can be observed. Then, the lifting push rod 301 operates, driving the lifting plate 302 and the support slide rail 303 to rise and reset. The rotary motor 201 operates, driving the drive plate 203 and the workstation seat 202 to rotate, moving the inspected workpiece 7 to the drop hole 102 to complete the automatic material discharge. At the same time, it also rotates the new workpiece 7 to the bottom of the clamping assembly 4, realizing the function of continuously and automatically detecting internal defects of the billiard cue. This embodiment is suitable for detecting internal defects of billiard cue parts connected by threads or clips, and can detect material cracks, broken threads or clips, misalignment and other problems.

[0029] Example 2: refer to Figure 7 , Figure 8 , Figure 9 , Figure 10The difference from Embodiment 1 is that the probe 5053 is set with a larger upper end and a smaller lower end. The bottom of the probe 5053 is provided with a pressure application component 8, which is used to apply pressure evenly to the inner wall of the material. The pressure application component 8 includes a central shell 801 fixedly installed at the bottom of the probe 5053 by a frame. Multiple pressure claws 802 are radially slidably arranged inside the central shell 801. One end of the multiple pressure claws 802 located inside the central shell 801 is fixedly connected to an elastic ring 803. A contact block 804 is axially slidably connected inside the central shell 801. The top of the contact block 804 is provided with a top contact portion 8041. The inner end of the pressure claw 802 is provided with an abutment portion 8021. The abutment portion 8021 can restrict the downward movement of the top contact portion 8041. After the contact block 804 is pressed upward, it can push the multiple pressure claws 802 to move radially. The purpose of the pressure application component 8 is to apply a uniform force to the side wall inside the billiard cue structure, which can cause slight deformation inside the billiard cue material. Based on the deformation state, the strength of the bond between various materials or components can be judged, thereby determining whether secondary gluing is required and improving the quality of the billiard cue product. Among them, the abutment part 8021 can limit the downward movement of the top part 8041 and prevent the contact block 804 from falling off. The specific operation is as follows: As the cylinder 504 drives the probe 5053 to move, it causes the pressure application component 8 to move downward as a whole. The bottom surface of the contact block 804 in the pressure application component 8 will contact the material of the inner wall of the billiard cue slot, causing the contact block 804 to move upward relative to the central shell 801. Since the contact block 804 has a small upper cross-section and a large lower cross-section, it will generate a radially outward thrust on multiple pressure claws 802. The pressure claws 802 overcome the elastic force of the elastic ring 803 and extend evenly. The pressure claws 802 will press against the inner wall of the material in the billiard cue slot, applying a uniform force. Similarly, when the contact block 804 does not contact the bottom wall of the billiard cue slot, the elastic potential energy accumulated by the elastic ring 803 can drive multiple pressure claws 802 back to their original positions. During this process, on the one hand, the pressure is applied evenly to avoid uneven force causing varying degrees of deformation within the cue slot, which could lead to irreparable material damage. On the other hand, it allows testing the strength of the adhesion between the cue materials and determining if there are any missed spots in the glue application. Through observation by the outer ring camera 5054 and the bottom camera 5055, if one pressure point rebounds faster than others, it indicates that the glue adhesion at that point is not strong. Conversely, if all points rebound at the same speed, it indicates that the glue coverage is complete and there is no weak adhesion between the surface and deeper materials. This allows for a direct visual indication of whether there are any weak glue adhesions between the internal materials of the cue, improving the quality of the cue product. This is particularly significant for the production of glued cue cues using multiple materials.
