Since the attaching surface of the polarizer is provided with a layer of film, which needs to be peeled off before the attaching operation to facilitate the attaching operation, the film peeling mechanism 7 is provided in the chip mounter in this embodiment to peel off the film of the polarizer supported on the second support assembly 12 to wait for the attaching operation; specifically, the film tearing mechanism 7 comprises a film tearing assembly 71 and a moving assembly 72 (see fig. 9), wherein the film tearing assembly 71 is used for peeling 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 as to facilitate the film tearing assembly 71 to peel off the film on the polarizer; preferably, in order to prevent the peeled film from polluting the environment, the blanking end of the film tearing mechanism 7 is further provided with a waste material collecting box, after the film tearing assembly 71 peels the film, the moving assembly 72 drives the film tearing assembly 71 to the upper part of the waste material collecting box, and the film tearing assembly 71 places the waste film in the waste material collecting box so as to collect the waste film for further processing.

In this embodiment, the output end of the attaching mechanism 1 is further provided with a discharging mechanism 8 for discharging the LCD glass attached with the polarizer, specifically, the discharging mechanism 8 is provided with a plurality of conveying rollers, the plurality of conveying rollers are connected with the discharging mechanism 8 through motor transmission, so that the plurality of conveying rollers rotate, and the plurality of conveying rollers can discharge the LCD glass attached with the polarizer.

Because two surfaces of LCD glass all need attached polaroid, after the attached operation of attached mechanism 1 completion one surface, still need be at another attached polaroid of surface, so this chip mounter has still set up turn-over mechanism 9 at the output of feed mechanism 8, and this turn-over mechanism 9 can carry out the turn-over with the LCD glass who attaches the polaroid to wait to get into next process, carry out the attached operation of polaroid of another surface again.

The working process of the chip mounter is as follows:

s1: the third feeding mechanism 5 feeds the LCD glass (with the short side facing the motion direction) into the rotating platform 21, the rotating platform 21 rotates 90 degrees around the Z axis, the CCD camera of the first feeding mechanism 2 shoots and positions the LCD glass on the rotating platform 21, then the rotating platform 21 moves along the X direction and the Y direction to adjust the position of the LCD glass, and a plurality of suckers on a manipulator of the first feeding mechanism 2 adsorb the LCD glass and place the LCD glass on the first support component 11;

s2: a fourth feeding mechanism 6 feeds the polaroids to a cleaning mechanism 4, the cleaning mechanism 4 cleans the polaroids, and then conveys the polaroids to a transfer platform 45, a CCD camera of the second feeding mechanism 3 shoots and positions the polaroids on the transfer platform 45, and then the transfer platform 45 moves along the X direction and the Y direction to adjust the positions of the polaroids, a plurality of suckers on a manipulator of the second feeding mechanism 3 adsorb the polaroids and place the polaroids on a second supporting component 12, a film tearing mechanism 7 pulls the film glass of the polaroids on the second supporting component 12, and a transfer platform 14 drives the second supporting component 12 and the polaroids to move to a second preset position;

s3: the first driving roller and the second driving roller are close to each other, the second supporting component 12 is driven to wind around one end of the second supporting component through the supporting part 133 and the jacking wheel 122, the other end of the second supporting component 12 is close to the first supporting component 11, the edge of the LCD glass is abutted against the edge of the polaroid, when the first driving roller and the second driving roller are respectively abutted against the edge of the LCD glass and the edge of the polaroid, the first driving roller and the second driving roller rotate to enable the polaroid to be attached to the LCD glass, then the blanking mechanism 8 blanks the LCD glass attached with the polaroid from the attaching mechanism 1 to the turnover mechanism, and the turnover mechanism turns the LCD glass attached with the polaroid for 180 degrees.

It should be noted that step S1 and step S2 may be performed simultaneously.

The attaching mechanism 1 of the chip mounter in the embodiment adopts the upper and lower driving rollers and the two driven rollers and is matched with the unpowered first supporting component 11 to directly attach the polarizer to the LCD glass, and compared with the conventional chip mounter adopting auxiliary devices such as a net cage, a film belt or an adhesive plate, the chip mounter in the embodiment avoids the use of the auxiliary devices, greatly simplifies the processing technology, improves the stability and utilization rate of equipment, improves the processing efficiency and quality, and reduces the defective product rate and cost; in addition, compare in the past and adopt the rubber roll to carry out the chip mounter of roll-in to LCD glass on attaching the platform, because damage LCD glass easily in the roll-in process, the chip mounter of this embodiment has adopted two upper and lower drive rolls of being made by rubber materials to carry out attached operation to LCD glass to promote yields and processingquality.

Example two

Because the polarizer needs to be cleaned, peeled, carried and the like before the attachment operation, the feeding rate of the polarizer is lower than that of the LCD glass, and therefore, in order to increase the feeding rate of the polarizer and prevent the phenomenon of material waiting, the embodiment is provided with two groups of second supporting assemblies 12 and two groups of transfer platforms 14 on the basis of the first embodiment, wherein the two groups of second supporting assemblies 12 are arranged at intervals along the X direction and are respectively rotatably arranged on the corresponding group of transfer platforms 14; because the two groups of second supporting assemblies 12 are arranged at intervals, one group of second supporting assemblies 12 can be directly moved to the lower part of the first supporting assembly 11 after being moved along the Y direction by the corresponding transferring platform 14, and the other group of second supporting assemblies 12 can be moved to the lower part of the first supporting assembly 11 after being moved along the X direction and the Y direction by the corresponding transferring platform 14; it should be noted that the transfer platform 14 may be driven by a motor and a lead screw nut, and of course, may also be driven by a motor and a driving wheel, and the driving method of the transfer platform 14 is not limited herein, as long as the transfer platform 14 can be driven to move.
