Description

Technical Field

[0001] The present invention relates to the technical field of coated glass detection, and specifically relates to a coated glass detection device. Background Art

[0002] After the production of coated glass is completed, in order to ensure that the coated glass can be used normally, the staff will measure the light transmittance and thickness of the coated glass through a measuring device. When measuring a large piece of coated glass with the existing measuring device, the staff needs to fix the coated glass on the detection table and drive the detection light source to move to measure multiple positions of the coated glass. However, the existing detection equipment is difficult to uniformly detect the various performances of the coated glass, and the detection processes are all carried out separately, resulting in an increase in the cost of the measuring equipment and a slow measuring efficiency.

[0003] Chinese Patent No. 202311644087.1, with the name of a coated glass detection device and its detection method, discloses an outer box, a detection table, a conveying mechanism, a limiting mechanism, a detection device and a controller. The detection table is installed inside the outer box, and the conveying mechanism is used to drive the coated glass to move into or out of the outer box. The limiting mechanism is installed on the top of the outer box, and the detection device is used to detect the thickness and light transmittance of the coated glass and collect the coated surface image of the coated glass. The controller is used to judge whether the coated glass is qualified according to the collected thickness, light transmittance and coated surface image. The above equipment can complete the light transmittance detection, thickness detection and appearance detection at one time, greatly improving the detection efficiency, and further analyzing the light transmittance according to the thickness detection data, improving the detection accuracy.

[0004] However, during the use of the above detection equipment, the following problems still exist: 1. When the coated glass is placed on the conveying mechanism, it is easy to be skewed, resulting in the side of the coated glass being easily rubbed against the outer box when passing through the inlet and outlet of the outer box; 2. It is impossible to clean the dirt (dust, fingerprints, hair, etc.) on the surface of the coated glass. During the light transmittance and appearance detection, the dirt will affect the detection results of the light transmittance, thickness and appearance, resulting in inaccurate detection results and detection errors.

[0010] Further, the above-mentioned detection component includes a distance sensor arranged on one fixing plate and adjacent to the second ball, a light source arranged on one fixing plate and adjacent to the second ball, and a receiver arranged on the other fixing plate and corresponding to the light source. The light source and the distance sensor are separated by the second ball.

[0011] Further, the above-mentioned cleaning mechanism further includes inclined frames arranged on the sides of the connecting rods away from the cleaning roller, and a collection box connected between the two corresponding inclined frames. A scraping blade is arranged on the bottom wall of the collection box in an upward inclined manner, and the scraping blade is in contact with the outer wall of the cleaning roller.

[0012] Further, a telescopic rod parallel to the cleaning roller is arranged inside one of the connecting rods on the U-shaped frame, the telescopic rod is located above the cleaning roller, a long rod corresponding to one end of the cleaning roller is arranged at the bottom of the telescopic end of the telescopic rod, a plurality of arc-shaped pushing blocks are arranged at intervals in a ring shape at one end of the cleaning roller, arc-shaped protrusions corresponding to the arc-shaped pushing blocks are arranged on the long rod, and a plurality of L-shaped friction rods in contact with the outer wall of the cleaning roller are arranged at intervals at the bottom of the telescopic end of the telescopic rod.

[0013] Further, second springs are respectively arranged between the corresponding fixing plates and the inner top wall of the outer shell and between the corresponding fixing plates and the top of the base, and the second springs are sleeved on the corresponding pressing rods.

[0014] Further, a centering and limiting mechanism for centering and limiting the coated glass is provided on the inner wall of the outer shell near the inlet;

[0015] The centering and limiting mechanism includes sliding rods symmetrically distributed on both sides of the outer shell and sliding through them respectively, connecting vertical plates respectively arranged at the ends of the sliding rods close to each other, two corresponding cross plates respectively arranged on the top side and the bottom side of the connecting vertical plates, several rollers rotatably connected between the two cross plates, and limiting plates arranged at the ends of the sliding rods away from each other. The limiting plates are located outside the outer shell. The outer edge of the roller corresponds to the side edge of the coated glass. A first spring is connected between the inner wall of the outer shell and the corresponding connecting vertical plate.

[0016] Further, the first spring is sleeved on the outer wall of the sliding rod.

[0017] Further, the first balls on the detection table are all on the same straight line and are distributed along the length direction of the detection table.

[0018] The present invention has the following beneficial effects:

[0019] 1. For the coated glass detection device of the present invention, when the coated glass passes above the detection table, several first balls on the detection table form rolling friction with the lower surface of the coated glass, which can avoid abrasion of the bottom surface of the coated glass; the coated glass is conveyed by the conveying mechanism and is moved into or out of the outer shell; the cleaning mechanism is used to clean the upper surface and the lower surface of the coated glass, and during the conveying process of the coated glass by the conveying mechanism, the cleaning mechanism can gradually clean the upper and lower surfaces of the conveyed coated glass. The thickness and light transmittance of the cleaned coated glass are detected by the detection component, which can greatly improve the detection accuracy.

[0020] 2. For the coated glass detection device of the present invention, by setting the cleaning mechanism, with the cooperation of the pushing member, the pressing rod, the fixing plate, the second balls, the U-shaped frame, the connecting rod, and the cleaning roller, starting the pushing member will drive components such as the pressing rod to approach the coated glass on the detection table. At this time, the cleaning roller will first contact the surface of the coated glass. The pushing member continues to push the pressing rod to move until the second balls contact the surface of the coated glass, and then the pushing member pauses moving. The pressing rod, in cooperation with the fixing plate and the second balls, can limit the coated glass; during the continuous movement of the pressing rod, under the action of pressure, it will drive the cleaning roller to move along the surface of the coated glass and towards the inlet direction. At this time, the connecting rod unfolds, and the surface of the coated glass can be wiped by the cleaning roller. And as the coated glass moves under the conveying of the conveying mechanism, rolling friction is formed between the cleaning roller and the coated glass, so that dust, fingerprints, etc. on the surface of the coated glass can be wiped off. Finally, when the thickness and light transmittance are detected by the detection component, the detection accuracy can be greatly improved.

[0021] 3. The cleaning mechanism of the present invention, through the cooperation of the inclined frame, the collection box and the scraping blade, can scrape off excessive dust and the like on the surface of the cleaning roller and collect it in the collection box, avoiding the repeated adhesion of the dust lamp on the cleaning roller to the coated glass and affecting its cleaning effect.

[0022] 4. The coated glass detection device of the present invention, through the cooperation of the telescopic rod, the long rod, the arc-shaped protrusion, the L-shaped friction rod and the arc-shaped push block, when the arc-shaped push block contacts the arc-shaped protrusion, it will push the long rod to move, and then drive the telescopic rod to extend. When the telescopic rod extends, it drives the L-shaped friction rod to move on the surface of the cleaning roller. When the arc-shaped push block does not contact the arc-shaped protrusion, the telescopic rod automatically resets, and then drives the L-shaped friction rod to move and reset on the surface of the cleaning roller. In this way, static electricity can be generated on the surface of the cleaning roller, and dust, hair and other impurities can be better adsorbed.

[0023] 5. The centering and limiting mechanism of the present invention, pulling the limiting plate can drive the sliding rod, the connecting vertical plate, the cross plate and the roller to move in the opposite direction. When the conveying mechanism transports the glass into the housing and corresponds to the roller, release the limiting plate, and finally drive the roller to contact the two sides of the coated glass, so as to cooperate with the conveying mechanism to gradually center the coated glass, and at the same time, under the action of the first spring, the two sides of the coated glass can also be limited.

[0031] The principles and features of the present invention will be described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not intended to limit the scope of the present invention.

[0032] As Figures 1 to 4 shown, in the embodiment of the present invention, a coating glass detection device is provided, including: a base 1, two detection tables 2 are symmetrically arranged along the length direction on the top of the base 1, there is a spacing between the two detection tables 2, a number of first balls 21 are arranged at intervals on the top of the detection table 2, and the first balls 21 on the detection table 2 are all located on the same straight line and are distributed along the length direction of the detection table 2; a outer shell 3 is arranged on the top of the base 1, an inlet 31 and an outlet 32 are respectively opened at both ends of the outer shell 3, the detection table 2 is located inside the outer shell 3, and both ends of the detection table 2 respectively extend out from the inlet 31 and the outlet 32 of the outer shell 3, the outer shell 3 is erected on the top of the base 1 and covers part of the detection table 2; a conveyor mechanism 4 for conveying the coating glass is arranged on the top of the base 1, the conveyor mechanism 4 includes conveyor rollers respectively rotatably arranged on the top of both ends of the base 1, sprockets respectively arranged on the rotating shafts of the two conveyor rollers, and a motor, mounting seats for mounting the conveyor rollers are respectively arranged at both ends on the top of the base 1, the motor is arranged on one side of a mounting seat and is used to drive the conveyor roller to rotate, and the two sprockets are driven by a chain, and an anti-slip layer can be arranged on the outer surface of the conveyor roller to avoid slipping during the conveying process; the above conveyor mechanism 4 is a prior art and will not be described in detail here.

[0033] A cleaning mechanism 6 for cleaning the upper and lower surfaces of coated glass is provided inside the housing 3, and a detection component 7 for detecting the thickness and light transmittance of the coated glass is provided on the cleaning mechanism 6; the distance between the two detection platforms 2 enables the cleaning mechanism 6 to pass through and clean the coated glass. In this embodiment, the top plane of the conveyor rollers on the conveyor mechanism 4 is flush with the plane formed by the first balls 21 on the detection platform 2. The coated glass is conveyed to the detection platform 2 through the conveyor mechanism 4. When the coated glass passes above the detection platform 2, a rolling friction is formed between several first balls 21 on the detection platform 2 and the lower surface of the coated glass, which can avoid abrasion of the bottom surface of the coated glass; and it is gradually conveyed into the housing 3 through the conveyor mechanism 4, and the upper and lower surfaces of the coated glass are cleaned by the cleaning mechanism 6 inside the housing 3. Thus, when the detection component 7 detects the thickness and light transmittance of the cleaned coated glass, the detection error can be greatly reduced, making the detection result more accurate.

[0034] Such as Figure 3 , Figure 4 and Figure 6As shown in the figure, the cleaning mechanism 6 includes pusher members 61 respectively and oppositely arranged at the top of the outer shell 3 and the top of the base 1. The pusher members 61 are cylinders or electric push rods. Pressing rods 62 are respectively vertically arranged on the moving ends of the two pusher members 61. A through hole is provided at the top of the outer shell 3 to facilitate the moving end of the pusher member 61 to pass through. The moving end of the pusher member 61 passes through the above through hole and extends into the outer shell 3, and is connected to the top of one pressing rod 62. An installation groove for installing the pusher member 61 is provided at the top of the base 1. The moving end of the pusher member 61 on the base 1 corresponds to the moving end of the pusher member 61 on the outer shell 3. The moving end of the pusher member 61 on the base 1 is connected to the bottom of the other pressing rod 62, so that the two pressing rods 62 are oppositely arranged and located on the same straight line. Fixing plates 63 are respectively arranged at one ends of the two pressing rods 62 close to each other. The fixing plates 63 are horizontally arranged and parallel to the base 1. Ball bearings two 64 are respectively arranged on one sides of the two fixing plates 63 close to each other. U-shaped frames 65 are respectively arranged on one sides of the two fixing plates 63 close to the inlet 31 of the outer shell 3. The U-shaped frame 65 on the upper fixing plate 63 is vertically arranged, so that the opening of the U-shaped frame 65 on the upper side faces upward. The U-shaped frame 65 on the lower fixing plate 63 is arranged upside down, so that the opening of the U-shaped frame 65 on the lower side faces downward. Connecting rods 66 are respectively hinged to the outer sides of the two ends of the U-shaped frame 65. The connecting rod 66 on the upper side is arranged obliquely downward, and the connecting rod 66 on the lower side is arranged obliquely upward and corresponds to each other. A cleaning roller 67 is rotatably connected between the two connecting rods 66 and is parallel to the tabletop of the detection table 2. The cleaning roller 67 on the upper side is used to clean the upper surface of the coated glass, and the cleaning roller 67 on the lower side is used to clean the lower surface of the coated glass. A torsion spring is provided at the connection position of the connecting rod 66 and the U-shaped frame 65. The cleaning roller 67 is arranged along the width direction of the outer shell 3. The length of the cleaning roller 67 is less than the distance between the two detection tables 2. The detection assembly 7 is arranged on one side of the fixing plate 63 and adjacent to the ball bearing two 64.

[0035] The detection assembly 7 includes a distance sensor 71 arranged on one fixing plate 63 and adjacent to the ball bearing two 64. The distance sensor 71 corresponds to the other fixing plate 63. A light source 72 is arranged on one fixing plate 63 and adjacent to the ball bearing two 64, and a receiver 73 corresponding to the light source 72 is arranged on the other fixing plate 63. In this embodiment, the light source 72 and the distance sensor 71 are located on the same fixing plate 63, and the light source 72 and the distance sensor 71 are separated by the ball bearing two 64.

[0036] When the conveying mechanism 4 conveys the coated glass to the position of the cleaning mechanism 6, two pushing members 61 are activated. The two pushing members 61 drive the corresponding pressure rods 62 to move towards the coated glass. At this time, the cleaning rollers 67 will first contact the upper and lower surfaces of the coated glass. The pushing members 61 continue to push the pressure rods 62 to move until the two second balls 64 contact the upper and lower surfaces of the coated glass. Then the pushing members 61 pause moving. The cooperation of the pressure rods 62 with the fixing plates 63 and the second balls 64 can limit the coated glass. The rolling friction formed by the second balls 64 and the coated glass can avoid abrasion on its surface. During the movement of the pressure rods 62, the connecting rods 66 will expand under pressure, thereby driving the cleaning rollers 67 to move along the surface of the coated glass and towards the inlet 31. The surface of the coated glass can be wiped by the cleaning rollers 67. And the coated glass moves under the conveyance of the conveying mechanism 4. A rolling friction is formed between the cleaning rollers 67 and the coated glass, so that dust, fingerprints, etc. on the surface of the coated glass can be wiped off. Finally, the thickness of the coated glass is detected by the distance sensor 71 on the detection component 7, and the light source 72 cooperates with the receiver 73 to detect its light transmittance, which can greatly improve the accuracy of the detection. When the two second balls 64 contact the upper and lower surfaces of the coated glass, the distance sensor 71 on one fixing plate 63 detects the distance D between it and the other fixing plate 63. The radius of the second ball 64 is R. The distance sensor 71 adopts an infrared ranging sensor or a laser ranging sensor. And the distance between the light-emitting port of the distance sensor 71 and the bottom end of the corresponding second ball 64 is H. Then the thickness B of the coated glass can be calculated, B = D - H - R.

[0037] Specifically, the cleaning mechanism 6 further includes an inclined frame 68 arranged on the side of the connecting rod 66 away from the cleaning roller 67, and a collection box 69 connected between two corresponding inclined frames 68. A scraping blade 610 is arranged on the bottom wall of the collection box 69 to incline upwards. The scraping blade 610 contacts the outer wall of the cleaning roller 67. The inclined frame 68 is connected to the outer wall of the connecting rod 66 by screws. The upper inclined frame 68 inclines upwards, and the lower inclined frame 68 inclines downwards, so that the collection box 69 does not interfere with the rotation of the cleaning roller 67. When the cleaning roller 67 rotates, the scraping blade 610 can scrape off excessive dust, etc. on the surface of the cleaning roller 67 and collect it in the collection box 69, avoiding repeated adhesion of dust, etc. on the coated glass and affecting its cleaning effect.

[0038] In another embodiment of the present invention, a telescopic rod 611 parallel to the cleaning roller 67 is arranged on the inner side of one of the connecting rods 66 on the U-shaped frame 65. The fixed end of the telescopic rod 611 is fixed to the inner side of the connecting rod 66 by screws; the telescopic rod 611 is located above the cleaning roller 67, and a long rod 612 corresponding to one end of the cleaning roller 67 is arranged at the bottom of the telescopic end of the telescopic rod 611. A plurality of arc-shaped push blocks 671 are arranged at intervals in a ring shape at one end of the cleaning roller 67. Arc-shaped protrusions 613 corresponding to the arc-shaped push blocks 671 are arranged on the long rod 612, and the arc-shaped protrusions 613 are located on the movement track of the arc-shaped push blocks 671; a plurality of L-shaped friction rods 614 in contact with the outer wall of the cleaning roller 67 are arranged at intervals at the bottom of the telescopic end of the telescopic rod 611, and the outer wall of the L-shaped friction rod 614 is wrapped with rubber. When the arc-shaped push block 671 contacts the arc-shaped protrusion 613, it will push the long rod 612 to move, thereby driving the telescopic rod 611 to extend. When the telescopic rod 611 extends, it drives the L-shaped friction rod 614 to move on the surface of the cleaning roller 67. When the arc-shaped push block 671 does not contact the arc-shaped protrusion 613, the telescopic rod 611 automatically resets, thereby driving the L-shaped friction rod 614 to move and reset on the surface of the cleaning roller 67. Repeating like this can generate static electricity on the surface of the cleaning roller 67 and can better adsorb impurities such as dust and hair.

[0039] In order to facilitate the quick reset of the pressing rod 62, a second spring is respectively arranged between the corresponding fixing plate 63 and the inner top wall of the housing 3 and between the corresponding fixing plate 63 and the top of the base 1, and the second spring is sleeved on the corresponding pressing rod 62. When the device is not in use, the pushing member 61 is closed, and under the action of the second spring, it can cooperate with the pushing member 61 to drive the pressing rod 62 to quickly reset, thereby enabling the cleaning mechanism 6 to quickly reset.

[0040] Such as Figure 3 and Figure 5As shown, a centering limiting mechanism 5 for centering and limiting the coated glass is provided on the inner wall of the outer shell 3 near the inlet 31; the centering limiting mechanism 5 includes sliding rods 51 that are respectively slidably inserted through both sides of the outer shell 3 and are symmetrically distributed. In this embodiment, the inlet 31 and the outlet 32 are provided on the left and right sides of the outer shell 3, and the sliding rods 51 are slidably inserted through the front and rear sides of the outer shell 3, that is, they slide along the width direction of the outer shell 3; connecting vertical plates 52 are respectively provided at the ends of the sliding rods 51 that are close to each other, and two corresponding cross plates 53 are respectively provided on the top side and the bottom side of the connecting vertical plates 52, and the cross plates 53 on the two connecting vertical plates 52 are both on the side close to each other; several rollers 54 rotatably connected between the two cross plates 53, the outer edge of the roller 54 corresponds to the side edge of the coated glass; and limiting plates 55 are provided at the ends of the sliding rods 51 that are far from each other, the limiting plates 55 are located outside the outer shell 3, sliding holes for the sliding rods 51 to pass through are respectively opened on the front side wall and the rear side wall of the outer shell 3, and a first spring 56 is connected between the inner wall of the outer shell 3 and the corresponding connecting vertical plate 52; and the first spring 56 is sleeved on the outer wall of the sliding rod 51. During use, pulling the limiting plate 55 can drive the sliding rods 51, the connecting vertical plates 52, the cross plates 53 and the rollers 54 to move in opposite directions. When the conveying mechanism 4 conveys the glass into the outer shell 3 and corresponds to the rollers 54, release the limiting plate 55, and finally the rollers 54 can be driven to contact the two side edges of the coated glass, so that the coated glass can be gradually centered in cooperation with the conveying mechanism 4, and at the same time, the two sides of the coated glass can be limited under the action of the first spring 56.

[0041] When the coated glass detection device of the present invention is in use, the conveying mechanism 4 conveys the coated glass to the detection table 2, and under the action of the centering limiting mechanism 5, the coated glass located on the detection table 2 can be centered, and at the same time, the two side edges of the coated glass can be limited; the upper and lower surfaces of the coated glass during conveying are cleaned by the cleaning roller 67 on the cleaning mechanism 6, and the cleaned glass is subjected to light transmittance and thickness detection by the detection assembly 7, so that the detection result is more accurate.

[0042] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
