[0002] LCD (Liquid Crystal Display) display screen is a commonly used display device. However, in order for LCD display screen to realize display function, a layer of polarizer must be attached to each of the two surfaces of its display glass to achieve display effect. At present, polarizers are attached to LCD glass using LCD mounters. However, when attaching polarizers, existing LCD mounters need to use auxiliary devices (such as mesh boxes) to fix and position the LCD glass before attaching, which greatly increases the complexity of the processing technology.

One end of the second support assembly away from the pressing assembly is rotatably connected to the transfer platform. When the first pressing portion and the second pressing portion are close to each other, the second pressing portion can drive the second support assembly to rotate around one end thereof so as to make the edge of the polarizer supported on the second support assembly contact with the edge of the LCD glass supported on the first support assembly so as to attach the polarizer to the LCD glass.

The first sticky roller can pick up dust and other debris on the surface of the polarizer to achieve a cleaning effect. The second sticky roller can pick up dust on the first sticky roller to achieve a dust collection effect.

[0032] Preferably, the viscosity of the second sticky roller is greater than that of the first sticky roller.

[0033] The viscosity of the second sticky roller is greater than that of the first sticky roller, so that all the dust on the first sticky roller can be picked up to collect the dust, thereby preventing the dust on the first sticky roller from causing secondary pollution to the polarizer and reducing the cleaning quality.

[0034] Preferably, the chip mounter further comprises:

[0035] The static electricity removal mechanism is configured to remove static electricity from the LCD glass and the polarizer.

[0036] The anti-static mechanism can remove static electricity on the LCD glass and polarizer to prevent the static electricity on the LCD glass and polarizer from absorbing dust in the air and affecting the processing quality. In addition, it can also prevent the LCD glass and polarizer from repelling each other when there is static electricity of the same sex on the LCD glass and polarizer, or from attracting each other when there is static electricity of opposite sex on the LCD glass and polarizer, which makes the attachment operation inconvenient and even causes the attachment operation to fail.

[0052] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0053] Embodiment 1

[0054] This embodiment provides a bonding machine that can bond polarizers to LCD glass. Figure 1-Figure 4 As shown, the chip mounter includes an attaching mechanism 1, a first feeding mechanism 2 and a second feeding mechanism 3. The first feeding mechanism 2 and the second feeding mechanism 3 both include a manipulator. The manipulator of the first feeding mechanism 2 can feed the LCD glass to a first preset position of the attaching mechanism 1, and the manipulator of the second feeding mechanism 3 can feed the polarizer to a second preset position of the attaching mechanism 1. It should be mentioned that the second preset position is located below the first preset position. The first feeding mechanism 2 and the second feeding mechanism 3 both include a positioning component. When the first feeding mechanism 2 and the second feeding mechanism 3 feed the LCD glass or the polarizer, the positioning component can first position the LCD glass. Or polarizer for positioning, and then use the robot to grab the LCD glass or polarizer, which improves the accuracy of the robot grabbing or placing the LCD glass or polarizer, avoids the use of auxiliary devices to position and fix the LCD glass, simplifies the processing technology, improves efficiency and reduces costs; in this embodiment, the positioning component is a CCD (Charge-Couple-Ddevice) camera, the CCD camera can position the LCD glass or polarizer, so that the robot can accurately grab the LCD glass or polarizer; the attachment mechanism 1 includes a first support component 11, a second support component 12 and a pressing component 13, LCD The glass can be supported on the first supporting assembly 11 (the first preset position is located on the first supporting assembly 11); the second supporting assembly 12 is spaced apart from the first supporting assembly 11, and the second supporting assembly 12 can approach or move away from the first supporting assembly 11 along the Z direction, and the polarizer can be supported on the second supporting assembly 12; the pressing assembly 13 includes a first pressing portion 131 and a second pressing portion 132, and the first pressing portion 131 and the second pressing portion 132 are spaced apart and rotatably arranged. When the second supporting assembly 12 is located below the first supporting assembly 11, the edge of the LCD glass and the edge of the polarizer are located between the first pressing portion 131 and the second pressing portion 132, and the second pressing portion 132 is spaced apart from the first pressing portion 131 and the second pressing portion 132. A pressing portion 131 and a second pressing portion 132 can approach each other along the Z direction, and drive the second supporting assembly 12 to approach the first supporting assembly 11, so that the first pressing portion 131 presses against the LCD glass and the second pressing portion 132 presses against the polarizer, so that the LCD glass and the polarizer are in contact with each other. When the first pressing portion 131 and the second pressing portion 132 rotate, the LCD glass and the polarizer move toward the rotation direction of the first pressing portion 131 and the second pressing portion 132 at the same time, so that the polarizer is attached to the LCD glass. The mounting machine can realize accurate loading of the LCD glass and the polarizer through a CCD camera, thereby improving the attachment accuracy of the attachment components.

[0055] Specifically, the manipulators of the first feeding mechanism 2 and the second feeding mechanism 3 can both move along the X direction and the Z direction, and a plurality of suction cups are arranged on the manipulators, and the plurality of suction cups can absorb LCD glass or polarizing film.

[0056] Furthermore, the SMT machine also includes a vacuum device. The multiple suction cups of the robot arm of the first loading mechanism 2 are connected to the vacuum device through a first control valve and an air pipe, and the multiple suction cups of the robot arm of the second loading mechanism 3 are connected to the vacuum device through a second control valve and an air pipe.

[0057] like Figure 5 As shown, the first pressing part 131 is a first active roller, which is rotatably arranged on the first pressing body, and the first pressing body can move along the Z direction and drive the first active roller to move, and the first active roller is connected to the first driving motor to drive the first active roller to rotate; the second pressing part 132 is a second active roller, which is rotatably arranged on the second pressing body, and the second pressing body can move along the Z direction and drive the second active roller to move, and the second active roller is connected to the second driving motor to drive the second active roller to rotate; in addition, a first driven roller 136 is rotatably arranged on the first pressing body, and the first driven roller 136 can roll and abut against the first active roller, and a second driven roller 137 is rotatably arranged on the second pressing body, and the second driven roller 137 can can roll and abut against the second active roller; in the present embodiment, the first active roller and the second active roller are both made of rubber material, and the first driven roller 136 and the second driven roller 137 are made of stainless steel material; since the first active roller and the second active roller are both made of rubber material, and when they are pressed against the LCD glass and the polarizer respectively, the first active roller and the second active roller will undergo a certain deformation, thereby affecting the attachment accuracy, so the first driven roller 136 and the second driven roller 137 are respectively rolled and abutted against the first active roller and the second active roller to prevent the first active roller and the second active roller from deforming, so as to improve the attachment accuracy; of course, the first active roller and the second active roller can also be made of stainless steel and rubber, and a stainless steel core shaft is used to make a core shaft, and the rubber material is coated on the surface of the core shaft.

[0058] like Figure 6 As shown, the pressing assembly 13 also includes a supporting portion 133, which is connected to the second pressing body so that the supporting portion 133 can move with the second active roller. A supporting portion 121 is provided at the bottom of the second supporting assembly 12, and the supporting portion 133 can selectively abut the supporting portion 121. When the second active roller moves toward the first active roller, the supporting portion 133 can abut the supporting portion 121 at the bottom of the second supporting assembly 12 to drive the second supporting assembly 12 to rotate around one end thereof, thereby making the edge of the polarizer contact with the edge of the LCD glass, so as to facilitate the polarizer to be attached to the LCD glass.

[0059] Specifically, the pressing assembly 13 also includes a first driving portion 134 and a second driving portion 135. The first driving portion 134 is transmission-connected to the second pressing body, and the first driving portion 134 can drive the second pressing body, the second active roller, the second driven roller 137 and the supporting portion 133 to move along the Z direction; the second driving portion 135 is transmission-connected to the first driving portion 134, and the second driving portion 135 can drive the second pressing body, the second active roller, the second driven roller 137, the supporting portion 133 and the first driving portion 134 to move along the Z direction. The supporting part 133 is driven by the first driving part 134 and the second driving part 135 at two stages, so that the second pressing body, the second active roller, the second driven roller 137 and the supporting part 133 move along the first active roller in the Z direction. When the second driving part 135 drives the second pressing body, the first driving part 134, the second active roller, the second driven roller 137 and the supporting part 133 to move a certain distance, the first driving part 134 drives the second pressing body, the second active roller, the second driven roller 137 and the supporting part 133 to continue moving in the same direction. The two-stage driving setting is helpful to control the driving force and driving distance.

[0060] Furthermore, the power source of the first driving unit 134 is a cylinder. Using the cylinder as the first driving unit 134 is helpful for controlling the driving force and the driving distance. When the first active roller and the second active roller press the LCD glass and the polarizer, since the gas in the cylinder is compressible, the cylinder can buffer the pressing force of the second active roller on the LCD glass and the polarizer to a certain extent to balance the pressing force, thereby preventing the first active roller and the second active roller from crushing the LCD glass and / or the polarizer. The cylinder in this embodiment is connected to the air source through an air pipe and a solenoid valve so that the cylinder can extend or retract.

[0061] In this embodiment, the pressing assembly 13 also includes a third driving unit 138 and a fourth driving unit 139. The third driving unit 138 can drive the second pressing body, the second active roller, the supporting unit 133, the first driving unit 134 and the second driving unit 135 to move along the X direction to prevent the second support assembly 12 from colliding with the second active roller or the supporting unit 133 when the second support assembly 12 moves to the bottom of the first support assembly 11, thereby playing a certain avoidance role; the fourth driving unit 139 can drive the first pressing body, the first active roller and the supporting unit 133 to move along the Z direction.

[0062] Preferably, a plurality of rollers are rotatably provided on the first supporting assembly 11, and the LCD glass is supported on the plurality of rollers. It should be mentioned that the plurality of rollers on the first supporting assembly 11 cannot rotate actively. When the first active roller and the second active roller rotate and drive the LCD glass and the polarizer to move, the LCD glass can drive the plurality of rollers on the first supporting assembly 11 to rotate. The plurality of rollers can reduce the wear of the first supporting assembly 11 on the LCD glass.

[0063] like Figure 6 As shown, a lifting wheel 122 is provided on the supporting portion 121 of the second supporting assembly 12. When the second active roller and the supporting portion 133 move a certain distance toward the second active roller, the supporting portion 133 can abut against the lifting wheel 122 to allow the second supporting assembly 12 to rotate around one end thereof. The lifting wheel 122 can convert the sliding friction between the supporting portion 133 and the supporting portion 121 into rolling friction, thereby reducing the friction force, thereby alleviating the wear of the supporting portion 133 and the supporting portion 121 and improving their service life.

[0064] like Figure 6 As shown, the attaching mechanism 1 also includes a transfer platform 14, which can move along the Y direction. The second support component 12 is supported on the transfer platform 14, so as to move the polarizer to a second preset position to wait for the attaching operation, and the end of the second support component 12 away from the pressing component 13 is rotatably connected to the transfer platform 14. When the first active roller and the second active roller approach each other, the supporting portion 133 can drive the second support component 12 to rotate around one end thereof, so that the edge of the polarizer supported on the second support component 12 contacts the edge of the LCD glass supported on the first support component 11, so as to attach the polarizer to the LCD glass. When the first active roller and the second active roller move away from each other, the second support component 12 returns to its initial position due to gravity.

[0065] In order to prevent the polarizer on the second support assembly 12 from shifting when the transfer platform 14 moves, a suction cup is provided on the second support assembly 12, and the suction cup is connected to the vacuum device through a third control valve and an air pipe. When the second loading mechanism 3 places the polarizer on the second support assembly 12, the suction cup on the second support assembly 12 adsorbs the polarizer. After the transfer platform 14 completes the movement, the suction cup releases the polarizer.

[0066] like Figure 7As shown, a rotating platform 21 is provided at the input end of the first loading mechanism 2, and the rotating platform 21 can rotate around the Z axis. The LCD glass can be supported on the rotating platform 21 to rotate the LCD glass to be processed to a certain angle, so that the first loading mechanism 2 can load the rotated LCD glass on the rotating platform 21; specifically, the rotating platform 21 includes a rotating platform 21 body, a plurality of rollers and a fifth driving unit, and the plurality of rollers are spaced and rotatably arranged on the rotating platform 21 body, and the fifth driving unit can drive the rotating platform 21 body and the plurality of rollers to rotate around the Z axis.

[0067] After the CCD camera of the first feeding mechanism 2 positions the LCD glass, the rotating platform 21 needs to adjust the position of the LCD glass on the rotating platform 21 so that the robot can accurately feed the LCD glass onto the first supporting assembly 11. Therefore, the rotating platform 21 can also support the LCD glass to move along the X direction and the Y direction. Specifically, two sets of slide rails extending along the X direction and the Y direction and a sixth driving unit are provided at the bottom of the rotating platform 21. The sixth driving unit can drive the rotating platform 21 to move along the X direction and the Y direction to adjust the position of the LCD glass.

[0068] The input end of the rotating platform 21 in this embodiment is also provided with a third loading mechanism 5 , on which a plurality of rollers are rotatably provided. The third loading mechanism 5 can load the LCD glass onto the rotating platform 21 through the plurality of rollers provided thereon.

[0069] When the third feeding mechanism 5 conveys the LCD glass to the rotating platform 21, in order to prevent the conveying force of the third feeding mechanism 5 from being too large and causing the LCD glass to fall from the rotating platform 21, the present embodiment further provides a stopper 211 on the rotating platform 21. The stopper 211 can stop the LCD glass when the third feeding mechanism 5 conveys the LCD glass to the rotating platform 21 to prevent it from continuing to move, thereby playing a certain stopping role. In addition, the stopper can also serve as an indicator for the CCD camera on the first feeding mechanism 2 to perform positioning operations, so as to facilitate the CCD camera to focus and shoot, thereby facilitating the CCD camera on the first feeding mechanism 2 to position the LCD glass.

[0070] In order to prevent impurities such as dust on the surface of the polarizer from affecting the attachment effect, the bonding machine is also provided with a cleaning mechanism 4, which is arranged at the input end of the second feeding mechanism 3. The cleaning mechanism 4 can clean the surface of the polarizer to remove impurities such as dust on the surface of the polarizer, thereby improving the attachment quality and product quality.

[0071] Specifically, the cleaning mechanism 4 includes two groups of cleaning components (see Figure 8), two groups of cleaning components are symmetrically arranged, and the two groups of cleaning components can clean the two surfaces of the polarizer respectively. Each group of cleaning components includes a cleaning component body 41, a first sticky roller 42 and a second sticky roller 43. The first sticky roller 42 is rotatably arranged on the cleaning component body 41 and pressed against the polarizer to pick up dust and other debris on the surface of the polarizer; the second sticky roller 43 is rotatably arranged on the cleaning component body 41 and pressed against the first sticky roller 42. The second sticky roller 43 can pick up dust on the first sticky roller 42 to achieve the effect of collecting dust.

[0072] Furthermore, the viscosity of the second sticky roller 43 is greater than that of the first sticky roller 42, so that all the dust on the first sticky roller 42 can be picked up to collect the dust, thereby preventing the dust on the first sticky roller 42 from causing secondary pollution to the polarizer and reducing the cleaning quality; the design of the two rollers with high and low viscosity of the cleaning component can completely remove the dust on the surface of the polarizer, and the dust removal efficiency is relatively high.

[0073] Preferably, the cleaning mechanism 4 also includes a conveying roller 44, which is arranged on one side of the two groups of cleaning components and is connected to the third drive motor for transmission. The conveying roller 44 can be pressed against the polarizer. When the third drive motor drives the conveying roller 44 to rotate, the conveying roller 44 can convey the polarizer between the two first sticky rollers 42, so that the two first sticky rollers 42 can pick up all the dust on the polarizer. It should be mentioned that the polarizer needs to be loaded from the side of the two groups of cleaning components where the conveying roller 44 is arranged.

[0074] In this embodiment, a fourth loading mechanism 6 is further provided at the input end of the cleaning mechanism 4, and the fourth loading mechanism 6 can load the polarizer from the polarizer material box to the cleaning mechanism 4. Specifically, the fourth loading mechanism 6 includes a manipulator, which is provided with multiple suction cups and can move along the Y direction and the Z direction. The manipulator can absorb the polarizer through the suction cups arranged thereon and place the polarizer on the cleaning mechanism 4. In addition, a transfer platform 45 is also provided at the output end of the cleaning mechanism 4. After the cleaning mechanism 4 cleans the polarizer, the conveying roller 44 transports the polarizer to the transfer platform 45, waiting for the second feeding mechanism 3 to feed the polarizer to the second supporting assembly 12. After the CCD camera of the second feeding mechanism 3 positions the polarizer on the transfer platform 45, the transfer platform 45 needs to adjust the position of the polarizer so that the robot of the second feeding mechanism 3 can accurately feed the polarizer to the second supporting assembly 12. Therefore, a moving part is also provided at the bottom of the transfer platform 45, which can drive the transfer platform 45 to move along the X direction and the Y direction to adjust the position of the polarizer. In order to prevent the polarizer from shifting when the transfer platform 45 moves, a locking portion is also provided on the transfer platform 45. After the cleaning mechanism 4 transports the polarizer to the transfer platform 45, the locking portion locks the polarizer. After the transfer platform 45 completes the movement, the locking portion unlocks the polarizer to prevent the polarizer from shifting and affecting the loading accuracy of the second loading mechanism 3.

[0075] In order to avoid static electricity generated during the transportation or attachment of LCD glass and polarizer, the mounter is also provided with a static electricity removal mechanism for removing static electricity on the LCD glass and polarizer to prevent the static electricity on the LCD glass and polarizer from absorbing dust in the air and affecting the processing quality. In addition, it can also prevent the LCD glass and the polarizer from repelling each other when there is static electricity of the same sex on the LCD glass and the polarizer, or from attracting each other when there is static electricity of opposite sex on the LCD glass and the polarizer, which makes the attachment operation inconvenient and even causes the attachment operation to fail. In this embodiment, the static electricity removal mechanism adopts a static electricity removal ion blower, and the static electricity ion wind blown by the static electricity removal ion blower can eliminate the static electricity on the LCD glass or the polarizer. The static electricity removal ion blower has multiple air outlets, and the multiple air outlets are connected to the static electricity generator through air ducts. The multiple air outlets can respectively blow air to the LCD glass on the third feeding mechanism 5, the polarizer on the second supporting assembly 12, the polarizer on the cleaning assembly, and the LCD glass and polarizer that are undergoing the attachment operation to eliminate static electricity.

[0076] Since a film is provided on the attachment surface of the polarizer, the film needs to be peeled off before the attachment operation to facilitate the attachment operation. Therefore, the bonding machine in this embodiment is provided with a film peeling mechanism 7 to peel off the film of the polarizer supported on the second supporting component 12 to prepare for the attachment operation; specifically, the film peeling mechanism 7 includes a film peeling component 71 and a moving component 72 (see Fig. 9 ), the film tearing assembly 71 is used to peel off the film on the polarizer, and the moving assembly 72 can drive the film tearing assembly 71 to move along the X direction, the Y direction and the Z direction, so that the film tearing assembly 71 can peel off the film on the polarizer; preferably, in order to prevent the peeled film from polluting the environment, a waste collection box is also provided at the unloading end of the film tearing mechanism 7. After the film tearing assembly 71 peels off the film, the moving assembly 72 drives the film tearing assembly 71 to the top of the waste collection box, and the film tearing assembly 71 then places the waste film in the waste collection box to collect the waste film for the next step of processing.

[0077] In this embodiment, a feeding mechanism 8 is also provided at the output end of the attaching mechanism 1 for feeding the LCD glass with the polarizer attached thereto. Specifically, a plurality of conveying rollers are provided on the feeding mechanism 8, and the plurality of conveying rollers are connected to the motor transmission of the feeding mechanism 8 so that the plurality of conveying rollers rotate, and the plurality of conveying rollers can feed the LCD glass with the polarizer attached thereto.

[0078] Since polarizers need to be attached to both surfaces of the LCD glass, after the attaching mechanism 1 completes the attaching operation on one surface, the polarizer needs to be attached to the other surface. Therefore, the attaching machine is also provided with a flipping mechanism 9 at the output end of the unloading mechanism 8. The flipping mechanism 9 can flip the LCD glass with the polarizer attached to it, so as to enter the next process and then perform the polarizer attaching operation on the other surface.

[0079] The working process of the placement machine is as follows:

[0080] S1: The third feeding mechanism 5 feeds the LCD glass (with the short side facing the moving direction) into the rotating platform 21, and the rotating platform 21 rotates 90 degrees around the Z axis. The CCD camera of the first feeding mechanism 2 takes a picture of the LCD glass on the rotating platform 21 for positioning, and then the rotating platform 21 is moved along the X direction and the Y direction to adjust the position of the LCD glass. The multiple suction cups on the manipulator of the first feeding mechanism 2 absorb the LCD glass and place the LCD glass on the first supporting assembly 11.

[0081] S2: the fourth feeding mechanism 6 feeds the polarizer to the cleaning mechanism 4. After the cleaning mechanism 4 cleans the polarizer, it is transported to the transfer platform 45. The CCD camera of the second feeding mechanism 3 takes a picture of the polarizer on the transfer platform 45 for positioning, and then the transfer platform 45 is moved along the X direction and the Y direction to adjust the position of the polarizer. The multiple suction cups on the manipulator of the second feeding mechanism 3 absorb the polarizer and place the polarizer on the second supporting assembly 12. The film tearing mechanism 7 removes the film glass of the polarizer on the second supporting assembly 12, and the transfer platform 14 drives the second supporting assembly 12 and the polarizer to move to the second preset position.

[0082] S3: The first active roller and the second active roller approach each other, and drive the second supporting assembly 12 around one end thereof through the supporting portion 133 and the lifting wheel 122, so that the other end of the second supporting assembly 12 approaches the first supporting assembly 11, so that the edge of the LCD glass and the edge of the polarizer are in contact with each other. When the first active roller and the second active roller are pressed against the edge of the LCD glass and the edge of the polarizer respectively, the first active roller and the second active roller rotate to attach the polarizer to the LCD glass, and then the unloading mechanism 8 unloads the LCD glass with the polarizer from the attaching mechanism 1 to the flipping mechanism, and the flipping mechanism flips the LCD glass with the polarizer 180 degrees.

[0083] It should be mentioned that step S1 and step S2 can be performed simultaneously.

[0084] The attaching mechanism 1 of the chip mounter in this embodiment adopts two upper and lower active rollers and two driven rollers and cooperates with the unpowered first support component 11 to directly attach the polarizer to the LCD glass. Compared with the previous chip mounters that used auxiliary devices such as mesh boxes, film tapes or adhesive plates, the chip mounter in this embodiment avoids the use of auxiliary devices, greatly simplifies the processing technology, improves the stability and utilization rate of the equipment, improves the processing efficiency and quality, and reduces the defective rate and cost; in addition, compared with the previous chip mounters that used rubber rollers to roll the LCD glass on the attachment platform, since the LCD glass is easily damaged during the rolling process, the chip mounter in this embodiment uses two upper and lower active rollers made of rubber material to attach the LCD glass to improve the yield rate and processing quality.

[0085] Embodiment 2

[0086] Since the polarizer needs to be cleaned, film-teared and transported before the attachment operation, the loading rate of the polarizer is lower than the loading rate of the LCD glass. Therefore, in order to improve the loading rate of the polarizer and prevent the phenomenon of waiting for materials, this embodiment is provided with two groups of second support components 12 and two groups of transfer platforms 14 on the basis of the first embodiment. The two groups of second support components 12 are arranged at intervals along the X direction and are respectively rotatably arranged on the corresponding group of transfer platforms 14; since the two groups of second support components 12 are arranged at intervals, one group of the second support components 12 can be directly moved to the bottom of the first support component 11 after being moved along the Y direction by the corresponding transfer platform 14, and the other group of the second support components 12 needs to be moved along the X direction and the Y direction by the corresponding transfer platform 14 before it can be moved to the bottom of the first support component 11; it should be mentioned that the transfer platform 14 can be driven by a motor and a lead screw nut, and of course, it can also be driven by a motor and a driving wheel. The driving mode of the transfer platform 14 is no longer limited here, as long as the transfer platform 14 can be driven to move.
