After glazing and baking and curing the surface of the glass product, a decal is applied to the surface of the glass container, and then it is sent into the decoration baking furnace to bake and cure the decal pattern to obtain a finished glass with a decal on the surface. In the prior art, whether the quality of the decal on the surface of the finished glass is qualified still depends on manual sorting and visual discrimination by the naked eye, which severely restricts the processing and production efficiency of glass products.

The driving wheel is driven by a motor to rotate, and the rotation direction of the belt is the same as the moving direction of the finished glass; An arc-shaped guiding rod is arranged outside the restraining frame of the rotating mechanism located at the outermost side of the entrance end of the detection mechanism.

Detailed implementation manners

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0018] Referring to Figure 1 and Figure 2 , in this embodiment, a baking furnace that can automatically detect and sort finished glass is proposed. The baking furnace mainly includes a heating mechanism 1, a conveyor belt 2, an air cooling mechanism 3, a detection mechanism 5, and a sorting mechanism 6.

[0019] The conveyor belt 2 is used for the conveying movement of glass products during the production and processing process, and it can adopt a chain structure. The conveyor belt 2 passes through the furnace chamber of the heating mechanism 1. In order for the decal patterns on the surface of the glass products to be baked and cured and to be detected and sorted as soon as possible after cooling, an air cooling mechanism 3 is provided at the outlet end of the heating mechanism 1.

[0020] The structure of the air cooling mechanism 3 mainly includes a bellows 31 in the shape of a Chinese character "冂" and an exhaust fan 32 installed on the top of the bellows 31. The suction end of the exhaust fan 32 extends into the bellows 31 to extract the heat of the finished glass passing through the conveyor belt 2 below the bellows 31, and the air outlet end is connected to the air filter 33 arranged above the heating mechanism 1. The air filter 33 purifies the extracted hot air and then discharges it from the factory area where the baking oven is located through a pipeline. In order to improve the fluidity of the air and speed up the cooling efficiency, a number of blowers 34 are arranged on both sides below the air cooling mechanism 3 to supply air to the conveyor belt 2. The blowers 34 blow air to the finished glass on the conveyor belt 2.

[0021] The conveyor belt 2 is installed on the frame 7 of the baking oven, the heating mechanism 1 and the air cooling mechanism 3 are installed in close parallel at one end of the frame 7, and the other end of the frame 7 is provided with a detection mechanism 5 and a sorting mechanism 6 in sequence.

[0022] The baffles 4 are used on both sides of the outlet end of the air cooling mechanism 3 to enclose a conical inspection channel 41 for guiding the travel path of the finished glass. The conical inspection channel 41 is convenient for uniformly gathering the finished glass scattered on the conveyor belt 2 into the inspection channel 41. The individual finished glass enters the inspection mechanism 5 in sequence through the inspection channel 41. The side of the baffle 4 is fixedly mounted on the frame 7 by a support rod, and the lower end surface of the baffle 4 does not contact the upper surface of the conveyor belt 2, which can guide the movement of the finished glass without hindering the rotation of the conveyor belt 2.

[0023] In the present embodiment, the working method of the baking furnace for automatically detecting and sorting finished glass is as follows: the glass products are guided along the conveyor belt 2 through the heating mechanism 1 and the air cooling mechanism 3 in turn to the detection mechanism 5 for finished product detection, and a sorting mechanism 6 for sorting the finished glass is set and established with a signal control connection at the exit of the detection mechanism 5; an image acquisition unit 51 is set in the detection mechanism 5 to extract the pattern on the surface of the finished glass, and the standard pattern in the template matching unit 52 is matched with the acquired pattern for detection to screen qualified finished glass.

[0024] like Figure 3 As shown, the sorting mechanism 6 includes a cylinder 61, a push block 62 and a drive control component 63 for controlling the start of the cylinder 61. The cylinder 61 and the drive control component 63 are both located on one side of the outlet of the detection mechanism 5. The cylinder 61 is an electric cylinder. The push surface of the push block 62 adopts an arc-shaped structure, which is more consistent with the arc-shaped surface structure of the finished glass, ensuring that no deviation occurs when the finished glass is pushed.

[0025] An instruction control connection is established between the drive control component 63 and the template matching unit 52 of the detection mechanism 5. The pushing block 62 is installed at the output end of the air cylinder 61. The outlet of the detection mechanism 5 communicates with the finished product channel 10. A defective product channel 11 is arranged on the outer side adjacent to the finished product channel 10. A hollow sorting port 64 is arranged on the partition between the finished product channel 10 and the defective product channel 11 corresponding to the area of the pushing block 62. If the detection result of the template matching unit 52 does not match, the drive control component 63 receives the control instruction from the template matching unit 52 to start the air cylinder 61 to push the pushing block 62, and pushes the unqualified finished product glass passing through the finished product channel 10 into the defective product channel 11 for centralized collection and processing. If the detection result of the template matching unit 52 matches the pre-input standard pattern, the template matching unit 52 does not send an instruction to the outside world and defaults that the finished product glass is a qualified product, and the finished product glass is conveyed through the finished product channel 10. Thus, the sorting work of the finished product glass is completed.

[0026] The air cylinder 61 starts only when it receives the control command from the drive control component 63. When not started, the output end of the air cylinder 61 is in a contracted state. In the contracted state, the pushing block 62 is located outside the finished product channel 10 and does not affect the movement of the finished product glass in the finished product channel 10.

[0027] The detection mechanism 5 is installed on the upper end surfaces of two bearing plates 8 above the conveyor belt 2. The side of each bearing plate 8 is fixed on the frame 7 of the baking furnace. The interval area between the two bearing plates 8 is the channel for the finished product glass to pass through the detection mechanism 5 via the conveyor belt 2 (this channel needs to meet the passing requirements of the finished product glass). A protective housing 9 covering the detection mechanism 5 is installed on the bearing plate 8. It should be noted that the protective housing 9 plays a protective role for the detection mechanism 5. In order not to affect the passing of the finished product glass, the height of the protective housing 9 is not limited.

[0028] As Figure 4 and Figure 5 shown, the detection mechanism 5 of this embodiment includes an image acquisition unit 51, a template matching unit 52, an image display board 53 and a searchlight 54. The image acquisition unit 51 and the template matching unit 52 establish an image information transmission connection and are both installed on the same one of the two bearing plates 8. A searchlight 54 that irradiates the image display board 53 is installed on the other bearing plate 8. The image display board 53 is vertically arranged on one side close to the bearing plate 8 where the image acquisition unit 51 is located. The lower part of the image display board 53 hangs down, and the upper part is fixedly installed on the protective housing 9; The standard pattern on the surface of the finished product glass is pre-input into the template matching unit 52. The bright light irradiated by the searchlight 54 projects the finished product glass onto the image display board 53 and is then collected in real time by the image acquisition unit 51. The image acquisition unit 51 transmits the acquired image to the template matching unit 52 for matching detection with the standard pattern, and transmits the detection result to the sorting mechanism 6.

[0029] Considering that after some decal patterns are baked and cured on the surface of the finished glass, the surface of the finished glass has a certain curvature, and it is difficult for the image acquisition unit 51 to ensure that the decal patterns on the surface of the finished glass can be completely acquired under a fixed viewing angle. Therefore, the finished glass needs to be rotated when the image acquisition unit 51 acquires an image. For this purpose, a rotating mechanism 55 is further provided on the detection mechanism 5. The rotating mechanism 55 is arranged side by side on the inner edge of each carrier plate 8 and is used to rotate the finished glass.

[0030] As Figure 6 shown, in this embodiment, the rotating mechanism 55 is composed of the following: A power machine 551, the output end of which is fixed to the telescopic rod 552 and provides telescopic power to the telescopic rod 552. The power machine 551 of this embodiment can be an air pump, a cylinder, a hydraulic machine or other devices that can provide a vertical telescopic amount. A telescopic bracket 553, the rear end of which is installed at the front of the telescopic rod 552, and the front end of which is installed at the rear of the constraint frame 554. The constraint frame 554 is in a rectangular frame structure, and a driving wheel 555 and a driven wheel 556 are respectively installed on both sides inside the frame. A belt 557 is sleeved on the driving wheel 555 and the driven wheel 556. The driving wheel 555 is driven to rotate by a motor. The rotation direction of the belt 557 is the same as the moving direction of the finished glass. When the finished glass enters the detection channel, the power machine 551 is started, and the telescopic rod 552 extends, driving the constraint frame 554 to move forward, so that the belt 557 contacts the surface of the finished glass. Under the movement of the belt 557, with the help of the contact friction force, the finished glass is caused to rotate, ensuring that the image acquisition unit 51 completely acquires the decal patterns on the surface of the finished glass under a fixed viewing angle.

[0031] An arc-shaped guide rod 558 is arranged on the outside of the constraint frame 554 of the rotating mechanism 55 at the outermost side of the entrance end of the detection mechanism 5, so as to facilitate the finished glass to smoothly enter the detection channel when moving.

[0032] It is worth mentioning that, in order to prevent the contact pressure generated by the rotating mechanism 55 from squeezing and breaking the finished glass, in this embodiment, starting from controlling the elongation of the telescopic rod 552, a strain gauge sensor for monitoring the rebound pressure of the restraint frame 554 is provided at the connection joint between the telescopic bracket 553 and the restraint frame 554 to measure the pressure when the finished glass contacts the belt 557, and transfer the contact pressure to the restraint frame 554. The contact pressure value on the restraint frame 554 is monitored by the strain gauge sensor, and the strain gauge sensor is connected to the controller of the power machine 551. According to the pressure value monitored by the strain gauge sensor, the output telescopic amount of the power machine 551 is adjusted by the controller. For example, first set the output amount of the power machine 551 (i.e., the elongation of the telescopic rod 552) according to experience, and also set the pressure threshold monitored by the strain gauge sensor. When the belt 557 contacts the finished glass, if the pressure value monitored by the strain gauge sensor exceeds the pressure threshold, it is positively fed back to the controller of the power machine 551, and the controller controls the output amount of the power machine 551 to decrease by a certain step until the pressure value monitored by the strain gauge sensor is less than the pressure threshold.

[0033] This embodiment also discloses the working principle method of a baking furnace capable of automatically detecting and sorting finished glass: After the glass products are surface-decorated, they are fed into the baking furnace along the conveyor belt 2 for baking and curing the decal patterns. The baked and cured glass products are cooled down by the air-cooling mechanism 3 to obtain the finished glass with decals on the surface. The finished glass enters the interior of the detection mechanism 5 in sequence along the incoming inspection channel 41 for finished product detection. The bright light irradiated by the searchlight 54 projects the patterns on the surface of the finished glass onto the imaging plate 53 and is collected by the image acquisition unit 51. The image acquisition unit 51 transmits the collected image to the template matching unit 52 for matching detection with the pre-input standard pattern, and calculates the position offset between the collected pattern and the standard pattern. If the offset is greater than the set tolerance threshold (the tolerance threshold can be set according to the specific size of the pattern of the finished glass machine, such as setting the tolerance threshold to 5 mm), it is determined that the matching of the finished glass is unqualified, and the detection result is transmitted to the sorting mechanism 6. After receiving the control instruction of unqualified matching from the template matching unit 52, the drive control component 63 of the sorting mechanism 6 starts the cylinder 61 to push the push block 62, and pushes the unqualified finished glass passing through the finished product channel 10 to the defective product channel 11 for transmission, while the qualified finished glass is transmitted through the finished product channel 10 to complete the sorting of the finished glass.

[0034] It should be noted that the finished glass appearing in this embodiment is not limited to Figure 4 the glass bottles shown in

[0035] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes should be covered within the protection scope of the present invention.

After receiving the control instruction of the template matching unit (52) indicating unqualified matching, the drive control component (63) of the sorting mechanism (6) starts the cylinder (61) to push the push block (62), thereby pushing the unqualified finished glass passing through the finished product channel (10) to the defective product channel (11) for transmission, and the qualified finished glass is transmitted through the finished product channel (10), thereby completing the sorting of the finished glass.
