Description

Technical Field

[0001] The present invention relates to the field of optical detection technology, and in particular to a detection device for producing OCA optical adhesives. Background Art

[0002] OCA optical adhesive is a transparent optical adhesive with high bonding strength, commonly used in electronic display devices. Its main purpose is to bond the display's protective glass, touch screen and display panel together while always maintaining good optical clarity and stability.

[0003] During production, OCA optical adhesive is usually processed into two forms: rolls and sheets according to different downstream application scenarios. The roll form is suitable for mass production of large-size display panels or scenarios that require continuous bonding, such as large-size LCD monitors and computer monitors. The sheet form is suitable for small-batch, multi-specification production needs, such as the specifications of small and medium-sized displays such as mobile phones and tablets.

[0004] Regardless of whether it is a coil or a roll, after production is completed, in order to ensure the quality of the product and prevent surface defects such as black spots, scratches or bubbles, a detection device must be used for detection. Existing detection technology uses visual, i.e., optical refraction instruments, to detect whether OCA optical glue has defects. However, due to the limitations of the structure of the detection device itself, it can usually only process OCA optical glue in the form of a roll. There are adaptability issues for OCA optical glue formed in the form of sheets, and different equipment needs to be used for detection, which increases the complexity and cost of the production line.

DETAILED DESCRIPTION

[0034] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] A testing device for producing OCA optical adhesives, such as Figures 1-14 As shown, a collecting device 4 is included. The collecting device 4 is the same as the prior art, and includes a device for collecting coils and sheets. A detection device 1 is installed at one end of the collecting device 4, and a feeding device 2 is provided at the end of the detection device 1 away from the collecting device 4.

[0036] Furthermore, in order to improve the versatility and adaptability of the detection device 1, the detection device 1 includes a lifting plate 102 slidably connected to the fixed frame 101, and the lifting plate 102 is driven by a first linear module to achieve up and down movement. At least one detection camera 106 is installed in the middle of the bottom surface of the lifting plate 102. The bottom surface of the lifting plate 102 is symmetrically rotated around the detection camera 106. The two rotating shafts 105 are each equipped with at least one first light source 107. The rotating shafts 105 are driven by a third driving member to achieve rotation. The first light source 107 illuminates symmetrically from both sides of the detection area, which can significantly reduce the local shadow problem caused by the single-sided light source, weaken the reflection interference, and improve the imaging clarity. In this way, the lifting plate 102 is driven by the first linear module to move up and down, and the distance between the detection camera 106 and the first light source 107 and the detected object can be flexibly adjusted. It can adapt to OCA optical adhesive products of different thicknesses and improve the adaptability of the equipment to products of different specifications. At the same time, the symmetry of the angle adjustment of the light sources on both sides is guaranteed by the third driving component to ensure that the light is evenly illuminated from both sides of the detection area.

[0037] Specifically, in order to uniformly adjust the light sources on both sides, the third driving member includes a first rope pulley 114 rotatably connected to the side wall of the lifting plate 102, one end of the rotating shaft 105 is fixedly connected to the second rope pulley 115, a torsion spring is provided between the rotating shaft 105 and the lifting plate 102, the first rope pulley 114 and the second rope pulley 115 are connected by a pull rope 116, that is, one end of the pull rope 116 is fixedly connected to the first rope pulley 114, and the other end is coiled on the second rope pulley 115, and the lifting plate 102 is mounted with a second driving motor 112, and the output shaft of the second driving motor 112 is connected to the second gear set 116. 11 is transmitted to the first rope wheel 114, and the second gear set 111 is composed of at least two gears meshing with each other, wherein the rotating shaft of one gear is fixedly connected to the first rope wheel 114, and the other gear is rotatably connected to the side wall of the lifting plate 102 and driven by the second drive motor 112 to realize rotation. Therefore, it can be seen that when the second drive motor 112 is started, the output shaft of the second drive motor 112 drives the first rope wheel 114 to rotate through the second gear set 111, and then the first rope wheel 114 tightens the pull rope 116, and then the first rope wheel 114 pulls the pull rope 116 so that the second rope wheel 115 The first light source 107 rotates synchronously with the rotating shaft 105, and the first light source 107 rotates synchronously with the rotating shaft 105 to adjust the illumination angle. When the second drive motor 112 rotates in the opposite direction, the output shaft of the second drive motor 112 drives the first rope pulley 114 to rotate in the opposite direction through the second gear set 111, and the first rope pulley 114 no longer reels the pulley 116, and the pulley 116 is in a relaxed state. At this time, the torsion spring releases the stored elastic potential energy, generates a reverse torque, and drives the rotating shaft 105 to rotate in the opposite direction, thereby adjusting the illumination angle. The first light source 107 is reset; it should be noted that the frequency of adjusting the light source angle of the OCA detection equipment is low, and the rotation angle of the first light source 107 is limited, generally within plus or minus thirty degrees, so that the deformation amplitude of the torsion spring is small, fatigue accumulation is slow, and the symmetrical selection of the torsion springs on both sides ensures consistent parameters. Combined with the rigid transmission of the gear set, it can offset the slight elastic force deviation of the spring and ensure the reset accuracy. Compared with other transmissions, such as synchronous belts, the combination of torsion spring and pull rope 116 has a simple structure, fewer failure points, lower cost, and easier maintenance.

[0038] Furthermore, in order to adapt to the feeding of sheets and coils, the feeding device 2 includes a feeding rack 201, and the feeding rack 201 is in a "T" shape that is rotated ninety degrees. A first slide groove 2011 is symmetrically provided on the side of the feeding rack 201 close to the detection device 1. A sheet feeding plate is slidably connected in the first slide groove 2011, and the sheet feeding plate is driven by a third linear module to move up and down. A coil feeding roller 202 is installed on the side of the feeding rack 201 away from the detection device 1, and a rotating rack 203 is symmetrically connected to the top of the feeding rack 201. The rotating rack 203 is driven by a third linear module to move up and down. The three driving motors 204 drive to realize rotation, and a conveying roller 205 is rotatably connected between the two rotating frames 203. The conveying roller 205 is driven to realize rotation by the first driving member. The conveying roller 205 is connected to a toggle lever that cooperates with the sheet loading plate. That is, when the sheet loading plate moves to the top of the loading frame 201, the first driving member drives the conveying roller 205 to rotate, and the toggle lever rotates with the conveying roller 205. Then, the toggle lever will toggle the sheet OCA optical adhesive on the sheet loading plate, so that the sheet OCA optical adhesive enters the detection device 1 for detection;

[0039] Specifically, the sheet feeding plate includes a first lifting plate 211 slidably connected to the first sliding groove 2011, the first lifting plate 211 is connected to the third linear module, and the end of the first lifting plate 211 away from the detection device 1 is rotatably connected to one end of the movable plate 212, and the other end of the movable plate 212 is transmitted to the first lifting plate 211 through the first elastic member 213, the first elastic member 213 is specifically a spring, and the end of the movable plate 212 close to the detection device 1 is symmetrically provided with a protrusion 214, the first lifting plate 211 is provided with a third groove 2111 for the protrusion 214 to move, and the loading frame 201 is provided with a second sliding groove 2012 for the protrusion 214 to move, wherein the vertical height of the second sliding groove 2012 is lower than the vertical height of the first sliding groove 2011. It can be seen that when the third linear module controls the first lifting plate 21 When the first lifting plate 211 is moved to the top, the protrusion 214 on the movable plate 212 contacts the top of the second slide groove 2012, so that the protrusion 214 contacts the top of the second slide groove 2012. At this time, the third linear module will still control the first lifting plate 211 to move upward a certain distance, thereby causing the top of the second slide groove 2012 to squeeze the movable plate 212, forcing the movable plate 212 to rotate around the hinge point with the first lifting plate 211 and tilt toward the direction of the detection device 1, thereby allowing the sheet on the movable plate 212 to slide off the movable plate 212. It should be noted that the purpose of tilting the movable plate 212 is to create a favorable posture, which belongs to "passive auxiliary posture adjustment". The toggle lever directly acts on the tilted sheet, solving the problem that the sheet may not be able to move independently by tilting alone. The two are in a synergistic and complementary relationship, and are not functionally redundant.

[0040] Specifically, the toggle rod includes a first sleeve 221 fixedly connected to the inside of the conveying roller 205, a second sleeve 222 is sleeved in the first sleeve 221, a third elastic member 223 is arranged between the second sleeve 222 and the first sleeve 221, the third elastic member 223 is specifically a spring, the second sleeve 222 is driven by the second driving member and can be retracted into the inside of the first sleeve 221, a toggle rod 224 is sleeved in the second sleeve 222, a second elastic member 225 is arranged between the toggle rod 224 and the second sleeve 222, the second elastic member 225 is specifically a spring, the elastic coefficient of the third elastic member 223 is greater than the elastic coefficient of the second elastic member 225, a soft pad is fixed to one end of the toggle rod 224 close to the sheet loading plate, wherein the second elastic member 225 can prevent the sheet from being damaged when toggling;

[0041] Specifically, the first driving member includes a first driving motor 233 mounted on the side wall of the rotating frame 203. The output shaft of the first driving motor 233 is transmitted to the conveying roller 205 through the first gear set 231. The first gear set 231 is composed of at least two mutually meshing gears, wherein the rotating shaft of one gear is fixedly connected to the conveying roller 205, and the other gear is rotatably connected to the rotating frame 203 and driven by the first driving motor 233 to rotate, thereby driving the conveying roller 205 to rotate.

[0042] Specifically, the second driving member includes a guide frame 241 symmetrically fixed to the inside of the conveying roller 205, a movable frame 242 is slidably connected to the guide frame 241, a fourth elastic member 243 is provided between the movable frame 242 and the guide frame 241, the fourth elastic member 243 is specifically a spring, the end of the movable frame 242 close to each other is fixedly connected to the guide inclined plate 244, a fixing rod 245 is fixedly connected to the side wall of the second sleeve 222, the fixing rod 245 abuts against the guide inclined plate 244, the first sleeve 221 is provided with a first movable groove 2211 for the fixing rod 245 to move, the end of the movable frame 242 away from each other is fixedly connected to a tapered block 246, and a fixing plate 247 that cooperates with the tapered block 246 is provided on the side of the loading frame 201 close to the coil loading roller 202;

[0043] It can be seen that when a sheet is needed, a sheet is placed on the top surface of the movable plate 212 by manual or mechanical means, and the third linear module is started. The third linear module drives the first lifting plate 211 to rise along the first slide groove 2011. Since the second slide groove 2012 is lower than the first slide groove 2011, when the protrusion 214 on the movable plate 212 contacts the top of the second slide groove 2012, the third linear module controls the first lifting plate 211 to continue to rise, thereby forcing the movable plate 212 to rotate around the hinge point and move toward the detection device 1. The movable plate 212 is tilted in the direction of the tilt, and after the movable plate 212 is tilted, the sheet begins to slide down due to gravity, but may stagnate due to friction, and needs the assistance of the toggle lever. Therefore, when the sheet feeding plate reaches the top of the second chute 2012, the first drive motor 233 is started, and the output shaft of the first drive motor 233 drives the conveying roller 205 to rotate through the first gear set 231, and then the toggle lever will rotate along with the conveying roller 205, and then the soft pad of the toggle lever 224 contacts and pushes the tilted sheet to overcome the friction, ensuring that the sheet smoothly enters the detection device 1;

[0044] When the coil needs to be loaded, the third drive motor 204 is started, and the output shaft of the third drive motor 204 drives the rotating frame 203 to rotate, and then the conveying roller 205 rotates along with the rotating frame 203, so that the conveying roller 205 switches from the sheet loading position to the coil loading position, and at the same time the fixed plate 247 squeezes the conical block 246, so that the two conical blocks 246 move away from each other, and then the conical block 246 drives the movable frame 242 and the guide inclined plate 244 to move away from each other, and then the guide inclined plate 244 squeezes the fixed rod 247. 5, so that the fixed rod 245 moves, and then the second sleeve 222 and the shift rod 224 are retracted into the first sleeve 221, and then the shift rod is retracted into the inside of the conveying roller 205, and then when the coil is loaded, the first drive motor 233 is started, and the output shaft of the first drive motor 233 drives the conveying roller 205 to rotate through the first gear set 231, and then the conveying roller 205 can play a guiding role. The purpose of rotating the conveying roller 205 is to reduce the friction between it and the coil and improve the stability of coil transportation.

[0045] Further, in order to avoid the sheet to be stagnant in the detection device 1, while optimizing the lighting conditions, the fixed frame 101 is symmetrically connected with sliding blocks 121 on the front and back sides, the sliding blocks 121 are driven to move up and down by the second linear module, at least one motorized roller 123 is installed on the sliding blocks 121, the first groove 1231 is arranged on the motorized roller 123, the second light source 124 is installed in the first groove 1231, the second light source 124 is arranged obliquely towards the detection area, the lighting color of the second light source 124 can be the same as or different from that of the first light source 107, for example, the first light source 107 uses white light, and the second light source 124 uses blue light, which can be used to detect small impurities or scratches on the surface, or the first light source 107 and the second light source 124 both use red light to detect the uniformity of the thickness of the adhesive layer, the lighting color of the first light source 107 and the second light source 124 needs to be adjusted according to the actual needs, as can be seen, during detection, the rotation of the motorized roller 123 and the second linear module can be used to adjust the illumination angle and range of the second light source 124, and then the second light source 124 and the first light source 107 form dynamic complementation, which can adapt to different types of defect detection requirements, and when the sheet enters the detection area and is detected, the second linear module is started to drive the sliding blocks 121 to descend, so that the motorized roller 123 is in contact with the surface of the sheet, then the motorized roller 123 is started to rotate and drive the sheet to move towards the collecting device 4 by friction, then the motorized roller 123 is reversed to rotate and reset by the second linear module, which can avoid the problem of wire winding of the second light source 124.

[0046] Furthermore, in order to remove particulate impurities on the surface of the coil or sheet and to prevent the coil from wrinkling during transportation, a pre-processing device 3 is further connected between the feeding device 2 and the detection device 1. The pre-processing device 3 includes a mounting frame 301 connected to the feeding frame 201 and the fixing frame 101. A motorized roller 302 is arranged between the mounting frames 301. First air injection holes 3021 are evenly distributed on the side wall of at least one motorized roller 302 located in the middle. A first nozzle 303 for injecting gas is installed inside the motorized roller 302 at the first air injection hole 3021. The technology of how to install the first nozzle 303 inside the electric roller 302 without affecting the rotation of the electric roller 302 is an existing technology. It generally includes a fixed tube fixedly connected to both ends of the mounting frame 301 and sleeved inside the electric roller 302. The fixed tube has an air vent and a rotatable ring is arranged outside the air vent. The ring is connected to the first air jet hole 3021 through a pipe. A "M"-shaped mounting plate 304 is fixed to the mounting frame 301. The bottom surface of the mounting plate 304 is rotatably connected to four rollers 305. The four rollers 305 are cross-distributed in an "X" shape. The four rollers 305 are connected through the fourth The driving member drives the synchronous rotation, wherein the two rollers 305 near the feeding device 2 are evenly distributed with second air injection holes 3051, and the second nozzle 306 for injecting gas is installed inside the roller 305 at the second air injection hole 3051. The second nozzle 306 uses the same technology as the first nozzle 303, so it will not be elaborated on in detail. The two rollers 305 near the feeding device 2 are frustum-shaped, and the ends with larger diameters are close to each other. In this way, when the coil passes between the roller 305 and the motorized roller 302, the larger end of the roller 305 will contact the coil, while the smaller end will not be touched. One end does not come into contact with the coil. If the middle area of ​​the coil is wrinkled due to insufficient tension, the cone-shaped roller 305 can generate a tangential force directed toward the edge, gradually "pushing" the wrinkled coil apart to avoid wrinkles. Since the first nozzle 303 and the second nozzle 306 are provided, when the coil or sheet passes through, the first nozzle 303 and the second nozzle 306 can respectively spray air on the upper and lower surfaces of the coil or sheet to remove surface particles. The proximity to the detection device 1 prevents the sheet from warping due to the air jet from the second nozzle 306 during the passage.
