Description

Technical Field

[0001] The utility model relates to coating equipment for coated glass, in particular to coating equipment with movable glass positioning points. Background Art

[0002] The glass to be coated is transported and operated on the coating equipment, and the coating spraying begins after it is fixed. The glass has two moving directions in the coating equipment, one is the forward and backward transportation direction, which is driven by the transmission roller and controls the glass to enter and exit the coating equipment; the other is the lateral adjustment direction, which is used to control the glass to be adjusted lateral to the specified position in the coating equipment to facilitate the spraying of coating materials. The coating equipment transmission system is equipped with multiple infrared glass travel and position detection electric eyes, which play the role of glass position detection and positioning. The current electric eye position is fixed. After the glass moves to the fixed position and is detected by the electric eye, it stops moving and is positioned there to wait for coating. At present, the electric eye position for the lateral adjustment direction is fixed and set at the edge, and the following problems often occur:

[0003] First, the width of the glass is different. If the glass is small, part of the drive roller will be exposed, and the coating material will be coated on the exposed drive roller and bottom baffle. The long-term accumulation of the coating layer will cause the film block to bulge, deform, and crack, thereby generating debris that falls on the glass to block the coating, resulting in the failure of the coating to coat part of the glass, and irregular "holes" and defective products. In this way, it is necessary to inspect and remove the film layer on the roller and bottom plate in advance, shortening the equipment maintenance and repair cycle, resulting in greater losses; at the same time, when the coating layer on the exposed side is thick to a certain extent, when coating larger width specifications of glass, it will contact the glass, causing scratches on the lower surface of the glass, and in severe cases, even causing the glass to deflect, stop, and collide, resulting in unnecessary abnormal shutdowns and repairs, resulting in greater losses.

[0004] Secondly, some coating types are sensitive to the thickness of the film layer, and the uniformity of the lateral film layer and color difference is difficult to control. The current electric eye is fixed at the edge of one side of the transmission roller. When the glass moves laterally in the coating equipment, all one side is close to the edge. During spraying, the lateral color difference between the edge position and the central position is large, and the thickness deviation of the film layer is also large, resulting in poor coating quality and a high defective rate. Utility Model Content

[0005] In order to solve the problem that the electric eye in the traditional glass coating equipment is fixed in position, the film layer can only be plated on a fixed empty space on one side during coating, and there is no way to avoid the continuous thickening of the film layer on the roller and the bottom plate in the local empty space, thereby causing the thick film layer to scratch the glass, the thick film layer to crack and fall off to cause "holes" in the film layer, and the color difference at this position is large, the utility model proposes a coating equipment with a movable glass positioning point.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] The lateral electric eye adjustment mechanism includes a moving track, a moving bar, and an electric eye. The moving track is installed in the coating area inside the coating equipment. The moving track extends along the X direction. The moving bar is installed on the moving track and moves along the X direction. The electric eye is installed on the moving bar.

[0015] Preferably, a positioning scale is installed on the moving track, and a proximity sensor is installed on the moving bar. When the proximity sensor detects the positioning scale, the driving device of the moving bar is turned off and the moving bar stops moving.

[0016] Preferably, at least one electric eye is installed on the moving bar.

[0017] Preferably, the electric eye is an infrared electric eye.

[0018] Compared with the prior art, the utility model changes the electric eye in the vertical direction (i.e., X direction) of the conveying roller into a structure that can move along a rigid track. The electric eye can move in the X direction, so that the fixed point position of the glass in the X direction inside the coating equipment can be continuously changed, and the beneficial effects are:

[0019] (1) By frequently adjusting the coating position of small-sized glass, the thickness of the film layer covered by the roller and the bottom plate due to exposure can be as uniform as possible, which can effectively reduce the accumulation of film layers on the roller and the bottom plate, reduce the occurrence of scratches on the lower surface of the glass, avoid excessive accumulation of film layers causing arching, deformation, and cracking, and avoid debris falling on the glass to block the coating, resulting in partial failure of coating on the glass, resulting in irregular "holes" and defective products, and improve the yield rate.

[0021] (3) Extending the equipment maintenance cycle and improving the production capacity of coating equipment. Traditional coating equipment needs to be cleaned and repaired every 20 days or so. The coating equipment of the utility model can extend the maintenance cycle to about 30 days, reducing the maintenance by 5 times per year, which is equivalent to an extra month of production time. On the one hand, it reduces the cost of maintenance manpower and material resources, and on the other hand, it improves production capacity. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] In order to provide a further understanding of the purpose, structure, features, and functions of the present invention, the present invention is described in detail below with reference to the embodiments.

[0027] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0028] Please refer to Figure 1 and Figure 2 , a coating device with a movable glass positioning point, comprising a longitudinal glass conveying mechanism 1, a transverse glass adjusting mechanism 2, and a transverse electric eye adjusting mechanism 3; the longitudinal glass conveying mechanism 1 and the transverse glass adjusting mechanism 2 are both installed in the coating area inside the coating device and used to support the movable glass, the longitudinal glass conveying mechanism 1 moves the glass in the Y direction, and the transverse glass adjusting mechanism 2 moves the glass in the X direction, wherein the Y direction is the moving direction of the glass entering and exiting the coating device, and the X direction is perpendicular to the Y direction;

[0029] The lateral electric eye adjustment mechanism 3 includes a moving rail 31, a moving bar 32, and an electric eye 33. The moving rail 31 is installed in the coating area inside the coating equipment. The moving rail 31 extends along the X direction. The moving bar 32 is installed on the moving rail 31 and moves along the X direction. The electric eye 33 is installed on the moving bar 32.

[0030] The working process of the coating equipment with movable glass positioning point of the utility model is as follows: first, the position of the electric eye 33 in the Y direction is fixed, and the position of the electric eye 33 in the X direction is adjusted by the horizontal electric eye adjustment mechanism 3; the moving bar 32 is moved along the moving track 31 until the electric eye 33 reaches the specified position and stops moving. The glass enters the coating equipment from the conveying device in the previous equipment, and the longitudinal glass conveying mechanism 1 supports the glass and conveys it along the Y direction. The glass enters the coating equipment along the Y direction until the electric eye 33 in the Y direction detects the edge of the glass, the longitudinal glass conveying mechanism 1 stops running, and the glass stops moving in the Y direction. At this time, the horizontal glass adjustment mechanism 2 is started, and the glass moves along the X direction under the support of the horizontal glass adjustment mechanism 2 until the electric eye 33 in the X direction detects the edge of the glass, the horizontal glass adjustment mechanism 2 stops running, and the glass stops moving in the X direction. The glass is adjusted in the coating equipment in the first Y direction and then in the X direction, so that the glass piece is located in the specified coating area to obtain the expected coating effect.

[0031] The utility model discloses a coating device with movable glass positioning points. Its main improvement lies in that the electric eye 33 perpendicular to the direction of glass entering and exiting the coating device (i.e., the X direction) is changed from a fixed installation structure to a structure movable along a rigid track. The position of the electric eye 33 in the X direction is adjustable, i.e., the fixed point position of the glass in the X direction is adjustable. For coating of small-sized glass, the electric eye 33 can be set at different intervals to make the fixed point position of the glass constantly change. The thickness of the film layer covered by the coating on the roller and the bottom baffle can be as uniform as possible, so that the film layer is not always coated at a certain position. In this way, the time for glass scratches and broken slag holes can be extended, the use efficiency of the coating device is improved, the output is increased, and defective products are reduced. At the same time, according to the actual lateral uniformity effect of the coating film layer, the device can adjust the glass fixed point position accordingly, so that the glass avoids the area with large coating color difference, improves the coating color uniformity, and improves product quality. Since the film layer covering the roller and the bottom baffle plate becomes more uniform as the position of the electric eye 33 moves, the maintenance period of the coating equipment can be extended accordingly. Traditional coating equipment needs to be cleaned and repaired once every 20 days or so. This solution can extend the maintenance period to about 30 days, reducing maintenance by 5 times per year, which is equivalent to an extra month of production time. On the one hand, it reduces the cost of maintenance manpower and material resources, and on the other hand, it improves production capacity.

[0032] In one embodiment, the longitudinal glass conveying mechanism 1 includes multiple rows of transmission rollers arranged along the Y direction, each row of transmission rollers includes multiple rollers 11 arranged along the X direction, and all rollers 11 rotate along the Y direction. The rotation of the rollers 11 drives the glass thereon to move along the Y direction, and the multiple rows of rollers 11 can be driven by a motor, or any other feasible driving method.

[0033] In a preferred embodiment, the transverse glass adjustment mechanism 2 includes a plurality of conveyor belts 21 arranged along the Y direction, each conveyor belt 21 extends along the X direction and rotates along the X direction, and the conveyor belt 21 drives the glass thereon to move along the X direction. The conveyor belt 21 can be driven by a motor, or any other feasible driving method available; the top end of the conveyor belt 21 is flush with the top end of the roller 11, so that both the longitudinal glass conveying mechanism 1 and the transverse glass adjustment mechanism 2 can move the glass thereon independently.

[0034] Furthermore, the multiple transmission belts of the transverse glass adjustment mechanism 2 are evenly interspersed and installed between the multiple rows of transmission rollers of the longitudinal glass conveying mechanism, so that the glass can be moved forward and backward in the Y direction in the coating area, and can also be moved left and right in the X direction, and the position movement adjustment speed is uniform and the distance is accurate.

[0035] In one embodiment, a positioning scale 34 is installed on the moving track 31, and the number of the positioning scale 34 is at least one. The positioning scale 34 allows the electric eye 33 to move quantitatively and accurately along the X direction on the moving track 31, thereby making the fixed point position adjustment of the glass in the X direction more accurate.

[0036] In one embodiment, when the number of positioning scales 34 is more than two, the intervals between two adjacent positioning scales 34 are equal, and the movable space of the glass in the X direction is evenly divided into a plurality of equal areas by the multiple positioning scales 34 with equal intervals, the fixed point position of the glass in the X direction changes constantly and evenly, and when a small-sized glass is coated thereon, the thickness of the film layer covered by the coating on the roller and the bottom baffle can be as uniform as possible.

[0037] The electric eye 33 moves in the X direction to adjust the fixed point position, which can be manual or electric control movement.

[0038] In one embodiment, the electric eye 33 is moved along the X direction by manual adjustment. In the lateral electric eye adjustment mechanism 3, the electric eye 33 is fixedly mounted on the moving bar 32, and the moving bar 32 is slidably connected to the moving track 31. Before the glass is coated, the operator directly drags the moving bar 32 by hand to slide on the moving track 31 until it moves to a predetermined position and then stops fixing.

[0039] In one embodiment, the electric eye 33 moves along the X direction by electric adjustment, and a driving device is installed on the moving bar 32. The moving bar 32 moves on the moving track 31 under the control of the driving device. The driving device can be externally connected to the control device of the coating equipment, or can be separately connected to a simple control switch.

[0040] In a more preferred embodiment, a positioning scale 34 is installed on the moving track 31, and a proximity sensor is installed on the moving bar 32. When the proximity sensor detects the positioning scale 34, the driving device of the moving bar 32 is turned off and the moving bar 32 stops moving. The proximity sensor can make the electric eye 33 move to the positioning scale 34 and stop automatically, thereby improving the degree of automation of the operation, simplifying the operating steps, and improving the displacement accuracy of the electric eye 33.

[0041] In one embodiment, at least one electric eye 33 is installed on the moving bar 32 to achieve different numbers of fixed-point positioning according to actual needs.

[0042] Preferably, the electric eye 33 is an infrared electric eye 33 .

[0043] In summary, the utility model makes the position of the infrared electric eye used for glass positioning in the coating equipment perpendicular to the direction of the glass entering and exiting the coating equipment (i.e., the X direction) adjustable, while ensuring the physical stability of the electric eye itself. By frequently adjusting the position of the coating of small-sized glass, the stacking of the film layer on the roller and the bottom plate is effectively reduced, the occurrence of scratches on the lower surface of the glass is reduced, and the yield rate is improved. At the same time, by adjusting the position of the glass, the coating area with large color difference can be effectively avoided, and the local color difference of the coated product can be avoided, thereby improving the quality of the product in terms of color uniformity. In addition, it can also effectively extend the equipment maintenance cycle and improve the production capacity of the coating equipment.
