Description

Technical Field

[0001] This utility model relates to the field of glass bottle inspection, and in particular to a photographic crack detection camera and a light source fixing bracket. Background Technology

[0002] During the production of glass bottles, it is necessary to inspect the finished glass bottles to detect defects such as cracks. To improve inspection efficiency and the accuracy of inspection results, existing technical solutions generally use integrated inspection machines to detect cracks in glass bottles.

[0003] The structure of comprehensive inspection machines is basically the same across manufacturers. They generally use a star wheel to drive the glass bottle to rotate one and a half revolutions. During the rotation of the glass bottle, a camera is used to take pictures or photoelectric detection is used to detect cracks in the glass bottle.

[0004] Currently, there are generally two ways to fix the camera and light source for photographic crack inspection: one way is to use a universal joint for fixing, which has the following problems: 1. The fixation is not firm, and the position of the camera and light source is easy to change; 2. A maximum of two sets can be installed at one workstation, and the inspection is not comprehensive enough; 3. It is not aesthetically pleasing.

[0005] Another method is to use a disc base with support rods. This method requires installing 4 sets at one workstation, and the 4 sets of support rods at the same workstation and the support rods between different workstations will interfere with each other, making it difficult to adjust. Utility Model Content

[0006] To solve the aforementioned technical problems, this utility model provides a photographic crack detection camera and a light source fixing bracket, including a first bracket and a second bracket that are separately arranged. The first bracket and the second bracket are distributed along the circumference of the star wheel disk and sequentially detect glass bottles.

[0007] The first bracket includes a first connecting plate that is radially slidably connected to the star wheel disk through a sliding adjustment part. A first support plate and a second support plate are fixed on the first connecting plate. The first support plate is connected to a first mounting plate and a plurality of cameras are mounted thereon. The second support plate is equipped with a light source through a first elongated hole and the second connecting plate.

[0008] The second bracket includes a sliding rod fixed to the star wheel disk by a mounting base. The sliding rod is provided with an axially adjustable clamping groove. The clamping groove is connected to the mounting rod through a rotation adjustment part. A light source and / or a camera are mounted at the bottom end of the mounting rod.

[0009] Preferably, the sliding adjustment part includes a guide rail fixed to the lower surface of the star wheel disk and a guide groove fixed to the first connecting plate. The guide rail and the guide groove are slidably engaged and locked by a clamp and a handle.

[0010] Preferably, the first elongated hole on the second support plate is arranged radially along the star wheel disk, and the light source is adjustablely mounted on the second connecting plate through the first arc-shaped hole.

[0011] Preferably, the first mounting plate is provided with a mounting part, the mounting part including a horizontal adjustment plate and a vertical adjustment plate, the horizontal adjustment plate adjusts the horizontal angle of the vertical adjustment plate through a second arc-shaped hole, and the vertical adjustment plate adjusts the vertical angle of the camera through a third arc-shaped hole and a fourth arc-shaped hole.

[0012] Preferably, the rotation adjustment part includes a fixed plate and a fastening plate fastened by bolts. The fixed plate is fixed to the clamping groove. A rotating ball is provided between the fixed plate and the fastening plate. The rotating ball locks the mounting rod through the groove and the third through hole.

[0013] Preferably, the fixing plate and the fastening plate are respectively provided with a first through hole and a second through hole, and the first through hole and the second through hole are provided with beveled surfaces, which abut against the rotating ball.

[0014] Preferably, the sliding rod and the clamping groove are axially adjusted through the groove and bolts and nuts.

[0015] Preferably, the mounting rod can be rotated and locked with multiple degrees of freedom via a rotating ball.

[0016] After adopting the above technical solution, the beneficial effects of this utility model are:

[0017] 1. By setting up sliding adjustment parts, first elongated holes, arc-shaped holes and rotating balls in the first and second brackets, multi-dimensional adjustment of the camera and light source in radial, axial and angular directions is realized. It can quickly adapt to star wheels or glass bottles of different sizes, significantly improve the equipment's compatibility with products of different specifications, and reduce equipment replacement costs.

[0018] 2. By independently setting the installation positions of the camera and light source, and using the horizontal adjustment plate, vertical adjustment plate and multi-arc hole structure in the mounting part, the camera can be finely adjusted in both horizontal and vertical directions. This design ensures that the camera is always facing the surface of the glass bottle, effectively avoiding imaging blur or blind spots caused by installation deviation, thereby greatly improving the accuracy and stability of crack detection.

[0019] 3. The first and second supports adopt a split design, which can inspect the glass bottles from different angles and directions. In addition, the positions of the light source and the camera are independently adjustable, which avoids mutual obstruction or light interference between multiple light sources or cameras during movement, ensuring that there are no blind spots in the inspection process, while reducing equipment debugging time and improving overall inspection efficiency.

[0020] 4. The linkage design between the clamping block and the handle, as well as the quick locking mechanism between the rotating ball and the clamping groove, make position adjustment only require simple turning or sliding, without the need for complicated tools. In addition, the modular installation structure facilitates partial maintenance or replacement, reducing the difficulty of equipment maintenance and downtime.

[0021] 5. The second bracket adopts a rotating ball and slot design with an angled surface, which allows the mounting rod to rotate freely and lock within a certain range. Combined with the axial adjustment function of the mounting rod, the light source and camera can achieve an asymmetrical layout, which is suitable for the inspection of glass bottles with complex curved surfaces. This multi-degree-of-freedom adjustment mechanism provides high flexibility for the inspection of special-shaped or irregularly shaped bottles. Attached Figure Description

To make the objectives, technical solutions, and advantages of this utility model clearer, the following description, in conjunction with the accompanying drawings and specific embodiments, will provide a further detailed description. It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit it. Those skilled in the art will recognize that this utility model can be implemented without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of this utility model by illustrating examples of it.

[0036] The directional terms used in the following description refer to the directions shown in the figures and are not intended to limit the specific structure of this utility model. It should also be noted in the description of this utility model that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0037] An embodiment of this utility model provides a photographic crack detection camera and a light source fixing bracket, see [link to relevant documentation]. Figure 1 It includes a first bracket 200 and a second bracket 300 respectively installed on the star wheel 101. The first bracket 200 and the second bracket 300 are distributed around the circumference of the star wheel 101. As the star wheel 101 drives the glass bottle 102 to switch positions, the first bracket 200 and the second bracket 300 sequentially complete the crack detection of the glass bottle 102.

[0038] See Figure 2, Figure 7 The first bracket 200 includes a first connecting plate 201, which is mounted on the star wheel 101 via a sliding adjustment part 210. The sliding adjustment part 210 enables the first connecting plate 201 to be adjusted radially along the star wheel 101.

[0039] The lower surface of the first connecting plate 201 is fixed to the first end of the first support plate 202 on the side away from the center of the star wheel disk 101. The second end of the first support plate 202 is fixed to the middle of the first mounting plate 203. Several cameras 204 are fixedly installed on the upper and lower sides of the first mounting plate 203.

[0040] A second support plate 205 is fixedly installed on the lower surface of the first connecting plate 201 near the center of the star wheel disk 101. A first elongated hole 206 is opened horizontally on the second support plate 205. The first elongated hole 206 is fastened to the first end of the second connecting plate 207 by bolts and nuts. A light source 208 is installed at the second end of the second connecting plate 207.

[0041] The first connecting plate 201 is distributed radially along the star wheel disk 101, and the second connecting plate 207 is set vertically.

[0042] The second connecting plate 207 is fastened to the first elongated hole 206 by bolts and nuts, so that the second connecting plate 207 can be adjusted radially along the star wheel 101 to adapt to the testing needs of star wheel 101 or glass bottle 102 of different sizes and specifications.

[0043] In addition, the first connecting plate 201 is adjusted radially along the star wheel 101 by the sliding adjustment part 210. Therefore, the rotation radius of the light source 208 and the several cameras 204 is adjustable during the rotation of the star wheel 101. Thus, before crack detection, the relative position of the first connecting plate 201 and the star wheel 101 is adjusted to ensure that the light source 208 and the several cameras 204 are facing the glass bottle 102, thereby facilitating the several cameras 204 to complete the photographic detection of cracks in the glass bottle 102.

[0044] The second bracket 300 includes a mounting base 301, which is fastened to the star wheel disk 101 by bolts. The lower surface of the mounting base 301 is fixed to the first end of the sliding rod 302. The outer surface of the sliding rod 302 is provided with a clamping groove 303 that can be adjusted along its axial direction. A rotation adjustment part 310 is fixedly installed on the clamping groove 303. A plurality of mounting rods 304 are adjustablely installed on the rotation adjustment part 310. A light source and / or camera are installed at the bottom of the mounting rods 304.

[0045] The clamping groove 303 has a through hole at its center that abuts against the sliding rod 302. The clamping groove 303 has a through groove on its side that is connected to the central through hole. Bolts and nuts are installed on the through groove. By tightening the bolts and nuts, the clamping groove 303 clamps the sliding rod 302.

[0046] In this embodiment, the first support 200 and the second support 300 are used to detect cracks in the glass bottle 102 from different angles and directions, ensuring the accuracy of crack detection. Furthermore, by setting the positions of the camera and the light source relatively independently, it is convenient to adjust the positions of the camera and the light source, thereby adapting to the detection needs of various glass bottles 102.

[0047] In addition, by setting the positions of the camera and light source relatively independently, interference between the cameras and light sources in different parts of the glass bottle 102 is avoided during the detection process.

[0048] For a further explanation of the above embodiments, see Figure 3 , Figure 4 The sliding adjustment part 210 includes a guide rail 211, which is fastened to the lower surface of the star wheel disk 101 along its length direction by a number of bolts. The guide rail 211 is distributed radially along the star wheel disk 101. The guide rail 211 is slidably arranged in the guide groove 212, which is fixedly connected to the upper surface of the first connecting plate 201.

[0049] Two clamping blocks 213 are installed on the side of the upper surface of the first connecting plate 201 away from the center of the star wheel disk 101. The two clamping blocks 213 are respectively located on both sides of the guide rail 211 and are connected by a screw. One clamping block 213 is threadedly connected to the screw, and the other clamping block 213 is rotatably connected to the screw. A handle 214 is fixedly installed at one end of the screw.

[0050] The above structure clamps the guide rail 211 with two clamping blocks 213, thereby limiting the position of the first connecting plate 201. When the position of the first connecting plate 201 needs to be adjusted, the handle 214 is turned so that the two clamping blocks 213 no longer clamp the guide rail 211. At this time, the first connecting plate 201 and the guide groove 212 can slide relative to the guide rail 211. After the first connecting plate 201 is adjusted to the target position, the two clamping blocks 213 are re-clamped on the guide rail 211 by turning the handle 214.

[0051] The bottom of the second connecting plate 207 is equipped with a light source 208 that can be adjusted by two sets of bolts and nuts. One set of bolts is configured in the first arc-shaped hole 209, which is located at the bottom of the second connecting plate 207. The center of the arc-shaped hole 209 coincides with the axis of the other set of bolts. This structure facilitates the adjustment of the tilt angle of the light source 208, making it easy to adjust the light source 208 to face the glass bottle 102, thereby ensuring the accuracy of camera detection.

[0052] For a further explanation of the above embodiments, see Figure 5 , Figure 6 The first mounting plate 203 is mounted with a camera 204 via a mounting part 220. The mounting part 220 includes a horizontal adjustment plate 221, which is fixedly mounted on the first mounting plate 203. A vertical adjustment plate 223 is fastened to the horizontal adjustment plate 221 by two sets of bolts. One set of bolts is located inside a second arc-shaped hole 222 on the horizontal adjustment plate 221, and the center of the trajectory of the second arc-shaped hole 222 coincides with the axis of the other set of bolts, so that the vertical adjustment plate 223 mounted on the horizontal adjustment plate 221 can be adjusted within a certain angle range.

[0053] The camera 204 is fixedly mounted on the longitudinal adjustment plate 223 by three sets of bolts. One set of bolts is located in the third arc-shaped hole 224, and the second set of bolts is located in the fourth arc-shaped hole 225. The third arc-shaped hole 224 and the fourth arc-shaped hole 225 are formed on the longitudinal adjustment plate 223, and the center of the trajectory of the third arc-shaped hole 224 and the center of the trajectory of the fourth arc-shaped hole 225 coincide with the axis of the third set of bolts. This structure allows the camera 204 mounted on the longitudinal adjustment plate 223 to adjust the elevation angle within its range of motion.

[0054] The mounting part 220 allows for easy adjustment of the vertical and horizontal angles of the camera 204, thus ensuring that the orientation of the camera 204 can be adjusted arbitrarily within a certain range. This facilitates directing the camera 204 towards the glass bottle 102, enabling precise imaging of the glass bottle 102 and improving the accuracy of crack detection.

[0055] For a further explanation of the above embodiments, see Figure 8 The rotating adjustment part 310 includes a fixed plate 311, a clamping groove 303 is fixed to the middle of the fixed plate 311, and a number of fastening plates 313 are fastened to the upper surface of the fixed plate 311 by bolts.

[0056] The fixing plate 311 has a plurality of first through holes 312, and the fastening plate 313 has a plurality of second through holes 314. The first through holes 312 and the second through holes 314 are aligned. The upper end of the first through hole 312 is chamfered, and the lower end of the second through hole 314 is chamfered. A rotating ball 315 is rotatably arranged between the first through hole 312 and the second through hole 314. The chamfered surface at the upper end of the first through hole 312 and the chamfered surface at the lower end of the second through hole 314 both abut against the outer surface of the rotating ball 315.

[0057] The rotating ball 315 has a third through hole 317 coaxially, and an installation rod 304 is installed in the third through hole 317. The rotating ball 315 has a slot 316 on its side that communicates with the third through hole 317.

[0058] In the above structure, when the bolts are tightened and the fastening plate 313 and the fixing plate 311 move closer to each other, the slot 316 narrows under the squeezing action of the beveled surfaces of the first through hole 312 and the second through hole 314, thereby enabling the third through hole 317 to hold the mounting rod 304 tightly. Conversely, when the bolts are loosened, the slot 316 widens under the action of elasticity, and the third through hole 317 no longer holds the mounting rod 304 tightly, thereby allowing the mounting rod 304 to slide and adjust relative to 307.

[0059] At the same time, when the bolt is loose, the rotating ball 315 can rotate in multiple directions within a certain angle range, that is, the mounting rod 304 can be set coaxially with the second through hole 314 and the first through hole 312.

[0060] By adjusting the above parameters such as length and angle, the camera and / or light source installed at the bottom of the mounting rod 304 can be adjusted in various combinations, providing convenience for crack detection.

[0061] The embodiments described above are not exhaustive, nor do they limit the scope of the present invention to the specific embodiments described herein. Clearly, many modifications and variations can be made based on the above description. These embodiments are selected and specifically described in this specification to better explain the principles and practical applications of the present invention, thereby enabling those skilled in the art to effectively utilize the present invention and its modifications. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
