Description

Technical Field

[0001] The utility model relates to the technical field of glass processing devices, in particular to a glass detection and placement device. Background Art

[0002] During the glass processing process or after it is formed, its appearance needs to be inspected, such as by visually inspecting the entire piece of glass using a camera, to ensure that it meets quality requirements. In the prior art, after the glass is processed and formed or during storage, it is placed in a material frame, such as the one disclosed in the whole-piece glass loading mechanism with application number 202222319976.8, to enable batch storage and transportation of glass. In order to ensure the number of glasses contained in the material frame, the gaps between the bars used to separate the glasses are relatively small. If the glass taken out of the material frame is placed back into the material frame after inspection, the glass in the middle position is not easy to take out and place under the premise that there is glass in front and behind it. On the one hand, more delicate operation is required, which wastes the time of taking out and placing the glasses. On the other hand, it may cause the taking out mechanism (such as a robotic arm or a suction cup, etc.) to damage the glass. If glass is stored on one side of the material frame for taking out the glasses and the other side is left vacant for placing the glasses, although it can be achieved that the taking out and placing of the glasses before and after the glass inspection does not affect each other, it will lead to a decrease in the utilization rate of the material frame. In addition, for the visual inspection of glass, the glass is usually positioned and then the camera is driven to move by a moving mechanism for inspection. This method also reduces the inspection efficiency of the glass. Utility Model Content

[0025] 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.

[0026] like Figures 1 to 3As shown, a glass detection and placement device includes a loading device 10, a moving device 20, a visual inspection device 30 and a receiving device 40. The loading device 10 is used to feed the glass 100 before detection, and the receiving device 40 is used to store and place the glass 100 after detection. The moving device 20 includes a manipulator 21 and a suction cup 22 for adsorbing the glass 100 provided at the output end of the manipulator 21. The suction cup 22 is driven by the manipulator 21 to adsorb the glass 100 from the loading device 10 to the visual inspection device 30 for detection and then placed in the receiving device 40. The visual inspection device 30 includes a machine table 301, a rotating motor 31, a transmission The movable part 32, the driving part 33 and the camera 34, the driving part 33 includes a guide rail 331, a first screw rod 3331, a second screw rod 3332 and a pair of nut blocks 332, the rotating motor 31 is arranged on the machine platform 301, and the output end thereof is provided with a transmission part 32, the first screw rod 3331 and the second screw rod 3332 are connected, and the threads on the two are arranged in opposite directions, one of the two is fixedly connected to the transmission part 32, such as connecting the first screw rod 3331 to the transmission part 32, a pair of nut blocks 332 are arranged on the guide rail 331, and are respectively sleeved on the first screw rod 3331 and the second screw rod 3332, a pair of cameras 34 are respectively arranged on the pair of nut blocks 332.

[0027] In the present invention, the robot 21 drives the suction cup 22 to absorb a piece of glass 100 from the loading device 10, and suspends the glass 100 in a horizontal state above the visual inspection device 30, the rotating motor 31 is activated, and the first screw rod 3331 and the second screw rod 3332 are driven to rotate synchronously through the transmission part 32. Since the threads on the first screw rod 3331 and the second screw rod 3332 are arranged in opposite directions, the two nut blocks 332 move closer to or away from each other, thereby driving a pair of cameras 34 to move closer to or away from each other, so that the two cameras respectively perform visual inspection on the two halves of the glass 100 synchronously; after the two cameras respectively inspect the two halves in a linear direction, the robot 21 drives the suction cup 22 and the glass 100 to move horizontally for a certain distance, and again completes the inspection in the linear direction through the pair of cameras 34; when the inspection of the entire glass 100 is completed, the robot 21 drives the suction cup 22 to place the glass in the receiving device 40 for stable placement. The above-mentioned coordinated action of a pair of cameras 34 that can move toward / away from each other and the manipulator 21 can quickly complete the inspection of the two opposite halves (left half and right half) on the glass, which improves the inspection efficiency compared to the reciprocating movement of a single camera. After the inspection is completed, the glass 100 is placed in the receiving device 40 for placement, avoiding the process of placing the inspected glass back in the loading device 10 due to the small space affecting the manipulator 21 to drive the suction cup 22 to adsorb the other glass that needs to be inspected. By loading on one side and unloading on the other side in a larger space, the efficiency of glass loading and unloading can be improved, thereby improving the efficiency of the entire glass inspection process.

[0028] As for the specific structure of the transmission part 32, it can adopt a belt drive method to ensure the accuracy of the movement of the camera 34, and can achieve full coverage of the glass detection range through precise movement. The specific structure of the transmission part 32 can include a driving wheel, a driven wheel and a transmission belt. The driving wheel is arranged at the output end of the rotating motor 31, the driven wheel is fixedly mounted on the first screw rod 3331, and the transmission belt is mounted on the driving wheel and the driven wheel to realize rotational output.

[0029] The loading device 10 includes a material frame 11 and a feeding mechanism 12. The material frame 11 is set on the feeding mechanism 12 and moves step by step. A plurality of glasses 100 are placed therein at intervals. Since the gap in the material frame 11 is small, it is not suitable for glass loading (processing) and testing and then placing the glass back in it. For the specific structure of the loading device 10, reference can be made to the applicant's prior application number 202222319976.8, a whole-piece glass loading mechanism, which discloses that the glass in the material frame can be taken out one by one, and after the previous piece of glass is taken out, there is a larger space in the material frame to facilitate the robot 21 to drive the suction cup 22 to absorb the next piece of glass. The larger space formed after the glasses are taken out one by one can make the operation more efficient and can also avoid damage to the glass.

[0030] like Figure 4 and Figure 5 As shown, based on the setting for placing the glass 100 after inspection separately, the material receiving device 40 includes a pair of material receiving mechanisms 41, the material receiving mechanism 41 includes a support platform 411, a material receiving frame 412 and a positioning assembly 413, the material receiving frame 412 includes a base frame 4121, side uprights 4122, rear uprights 4124 and a top plate 4123, a plurality of side uprights 4122 and a plurality of rear uprights 4124 are respectively arranged between the base frame 4121 and the top plate 4123, and a plurality of support columns 412a extending toward each other are provided on the relatively arranged side uprights 4122 from top to bottom, the lower end of the base frame 4121 abuts against the support platform 411, and is clamped at the diagonal point by a pair of positioning assemblies 413. A multi-layer placement space is formed in the receiving frame 412 by the support columns 412a provided. The glass 100 that has completed the inspection can be placed from bottom to top, which has a larger placement space, can improve the operation efficiency of the material moving device 20, and is not easy to cause damage to the glass; the setting of the rear vertical rod 4124 can limit the final position of the glass in the horizontal direction; in addition, the receiving frame 412 can be easily removed, and the glass placed in it after inspection can be moved in batches through the receiving frame 412 to the next process.

[0031] In addition, a plurality of auxiliary support rods 412b are provided on the rear vertical rod 4124 from top to bottom. The upper ends of the auxiliary support rods 412b are flush with the upper ends of the support columns 412a. While the support columns 412a support both sides of the glass, the auxiliary support rods 412b can support the middle position of the bottom surface of the glass to ensure the stability of the glass placement; the support column 412a is cylindrical, and the upper end surface of the auxiliary support rod 41ab is a flat structure, which can increase the contact area with the bottom surface of the glass to prevent the glass from slipping.

[0032] Preferably, the support platform 411 includes a bracket 4111 and a floating cylinder 4112 arranged on the bracket 4111. The lower end of the base frame 4121 abuts against the floating cylinder 4112. The floating support can prevent the material receiving frame 412 from resonating due to the surrounding environment, thereby ensuring the stability of the glass placed in the material receiving frame 412.

[0033] The positioning assembly 413 includes a translation cylinder 4131, a mounting plate 4132 and a roller 4133. The translation cylinder 4131 is arranged on the support platform 411, and a mounting plate 4132 is provided at the output end. A pair of rollers 4133 are arranged on the mounting plate 4132 for respectively abutting against the two side edges of the corners of the base frame 4121. Therefore, a pair of translation cylinders 4131 located at the diagonal position drive the four rollers 4133 to jointly clamp the diagonals of the base frame 4121 to position the material receiving frame 412. The rolling abutment between the rollers 4133 and the base frame 4121 can ensure that the position of the material receiving frame is centered, and ensure that the position of the material receiving frame 412 is accurate.

[0034] In the present invention, the receiving mechanism 41 can be configured to have two parts, namely a qualified product receiving mechanism and a defective product receiving mechanism, wherein the defective product receiving mechanism is used to place the glass that fails the visual inspection.

[0035] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.
