The mechanism features for the above solution are explained as follows:

this scheme design's a display screen module laminating equipment assembly line, concrete work flow is as follows:

the first step is as follows: placing the product; the display screen back plate module is placed on the jig plate to ensure that the display screen back plate module is not damaged when being processed on a production line, and then the jig plate and the display screen back plate module are placed on a speed doubling chain conveying line together for conveying and are processed through a series of equipment;

the second step is that: sticking an adhesive tape; the periphery of the frame of the display screen backboard module is pasted with the adhesive tape, the adhesive tape has the function of limiting the range of glue, the glue dispenser can only dispense glue in the range of the adhesive tape, and the glue is prevented from overflowing to other parts outside the frame of the backboard; the sticky tape technology is accomplished by operating personnel is manual as auxiliary work, and the sticky tape platform is operating personnel's work area, and its effect will be at the tool board that doubly fast chain transfer chain removed and display screen backplate module temporary transfer to the operating personnel's of both sides work area, and specific theory of operation is: the first cylinder pushes the adhesive tape pasting platform frame, a guide wheel at the bottom of the adhesive tape pasting platform frame moves on a long track arranged on a bottom plate, the frame drives the roller line working platform to be close to the speed-doubling chain conveying line, so that the roller and the speed-doubling chain conveying line are in butt joint, a display screen product can be transferred onto the roller line working platform from the speed-doubling chain conveying line, then the first cylinder is controlled to retreat, the frame and the roller line working platform are driven to return to the original positions, an operator carries out adhesive tape pasting work, after the work is finished, the first cylinder is driven to enable the roller line working platform to be in butt joint with the speed-doubling chain conveying line again, then the driving device drives the roller to rotate, the display screen product is transferred onto the speed-doubling chain conveying line, the whole work is finished, and because the adhesive tape pasting work can take longer time, four adhesive tape pasting platforms are arranged at the left side and the right side of, the working efficiency is ensured.

The third step: dispensing; after the display screen backboard module is pasted with the adhesive tape, the adhesive tape needs to be dispensed, and the operating principle of the dispenser is as follows: after the display screen backboard module moves to the dispensing platform of the dispensing machine, the limiting mechanism on the dispensing platform can prevent the display screen backboard from continuously moving forwards, then a dispensing pipe above the dispensing platform can move under the driving of the three-axis transmission mechanism (the three-axis transmission mechanism is used for driving the dispensing pipe to move in the front-back direction of an X axis, the left-right direction of a Y axis and the up-down direction of a Z axis, the prior art is adopted), dispensing is carried out on each part on the display screen backboard module, meanwhile, in order to adapt to display screens of different sizes, an adaptive width-adaptive guide mechanism is further arranged on the dispensing machine.

The fourth step: scraping glue; after having glued at display screen backplate module point, need scrape its surface glue evenly, realize through the frictioning machine, the theory of operation of frictioning machine is: when the display screen module after glue dispensing moves onto a glue scraping platform of a glue scraping machine, a limiting mechanism on the glue scraping platform can prevent a display screen back plate from continuously moving forwards, a cross beam moves back and forth on a left linear rail and a right linear rail to drive a glue scraping plate to scrape glue on the display screen (the moving of the cross beam on the linear rails utilizes the matching of a driving motor and a traditional ball screw mechanism, and the specific principle is not specifically explained again); the glue collecting grooves at the left side end and the right side end can just receive glue spread from the side surfaces, when the glue scraping plate moves to the tail end, more glue can be stored at the tail end and can drip along the display screen, and at the moment, the glue collecting grooves at the tail end can just receive the dripping glue, so that the glue can not drip on the equipment in the whole process; meanwhile, the two side glue connecting grooves and the tail glue connecting groove can be adjusted in position through the left transplanting device, the right transplanting device, the front transplanting device and the rear transplanting device respectively, and therefore the display screen with the side glue connecting grooves and the tail glue connecting grooves are suitable for display screens with various sizes.

The fifth step: heating and aging the glue; after glue on the surface of the display screen backboard module is uniformly scraped, the glue is water glue, and the water glue setting time is long, so when the display screen backboard module is attached to the liquid crystal display screen module, the water glue can easily flow into the liquid crystal display screen to cause the product to be damaged, and meanwhile, the fixing effect is not obvious, so the water glue needs to be heated and dried, and glue aging equipment is applied to the production line to heat and age the glue on the surface of the display screen backboard module, so that the setting speed of the glue is accelerated; the working principle of the glue aging equipment is as follows: because many glue aging mechanism have been set up altogether, when the display screen backplate module moved the ageing mechanism department of first group glue, the mechanism of clamp down presss from both sides out the display screen product from doubly fast chain conveying line, rethread parallel guide moves and carries out glue heating ageing on the heating platform of both sides, meanwhile, the display screen product of back can not consequently pause longer time, but can continue to move forward, move to the ageing mechanism department of second group glue and carry out glue ageing, analogize in proper order, can realize that a plurality of display screen products carry out glue heating ageing simultaneously, glue heating ageing time is about 5-8 minutes, after ageing the completion, rethread clamp the mechanism and put back the display screen backplate module and continue to carry forward on doubly fast chain conveying line.

And a sixth step: after the glue is aged, the adhesive tape attached to the display screen backboard module needs to be torn off, and the adhesive tape belongs to an auxiliary article and cannot be assembled on the display screen because the work of the adhesive tape is finished; since the structure of the tape tearing platform and the structure of the tape pasting platform are the same, the working principle of the tape tearing platform and the tape pasting platform are also the same, and repeated description is not provided herein; simultaneously, the work of tearing the sticky tape is simple some for pasting the sticky tape, so only need set up two in the left and right sides of doubly fast chain transfer chain and tear the sticky tape platform can.

The seventh step: transferring the product; in the step, the display screen back plate module is required to be transferred to overturning and laminating equipment, and the display screen back plate module is required to be laminated with the liquid crystal display screen module; the lift floor truck is exactly used for shifting display screen backplate module, and the theory of operation of dolly is: move the floor truck to doubly fast chain transfer chain tail end earlier, then adjust lift platform's height through the telescopic link, make lift platform keep level with doubly fast chain transfer chain, then display screen backplate module can get into on lift platform's the gyro wheel under the guide of doubly fast chain transfer chain, make the whole lift platform that gets into of display screen under the guide of gyro wheel, then carry to upset laminating equipment through the floor truck, adjust the telescopic link once more and make lift platform and tipping equipment's laminating platform keep level, then with the display screen from lift platform push laminating platform can, whole process does not need artifical transport.

Eighth step: product fitting; this step is last step, laminates the equipment from top to bottom with display screen backplate module and liquid crystal display module, realizes through using the upset rigging machine, and the theory of operation of upset rigging machine is: the front side of an upper turning vacuum suction plate faces upwards, a display screen back plate module is placed on the upper turning vacuum suction plate, a back plate is adsorbed through a vacuum suction hole, the position of the back plate is shot through a first camera after the position of the back plate is unchanged, the first camera transmits a shot picture to a control system of the whole equipment, and the shot picture is accurately analyzed by the control system and then is controlled to be accurately glued at a set position (the glue gluing device is used for gluing RTV glue on the surface of the back plate module to ensure the gluing effect); the glue dispenser and the first camera move synchronously, which means that the first camera takes a picture, and the glue dispenser performs one-time glue dispensing; the glue dispenser and the first camera can move on the front and back translation rails through the first door-shaped support to realize front and back movement, and can move left and right through the movement of the glue dispenser and the first camera on the first left and right translation rails on the cross beam (the moving principle of the glue dispenser and the first camera on the first left and right translation rails is realized by matching a common ball screw structure with a motor for driving, so that the specific description is omitted, and the same also applies hereinafter). The first camera records a specific position when photographing the backboard, the second camera photographs the display screen module placed on the lower laminating platform, the second camera can move on the front and back translation rails through the second door-shaped support to realize front and back movement, and the second camera can move on the second left and right translation rails on the cross beam to realize left and right movement; meanwhile, after the dispensing of the back plate is finished, the upper turning vacuum suction plate is controlled to turn over and translate to the position right above the display screen module, and then the control system analyzes the back plate position picture shot by the first camera and the display screen module position picture shot by the second camera respectively, integrates the back plate position picture and the display screen module position picture into data and carries out accurate calculation; the UVW aligning platform is controlled to be located at the bottom of the lower laminating platform after calculation is completed, the front position and the rear position and the angle of the display screen module can be adjusted through the UVW aligning platform, so that the back plate and the display screen module are aligned vertically, finally, the upper turning vacuum suction plate is driven by the air cylinder to move downwards to enable the display screen back plate module and the display screen module to be laminated together in a translating mode, and the finishing process of gluing, aligning and laminating is completed at last.

The operation principle of the self-adaptive left-right translation mechanism arranged on the tape pasting platform and the tape tearing platform is as follows: the main effect of translation mechanism about self-adaptation is that position about adjusting whole roller line work platform guarantees roller line work platform and the accurate butt joint of doubly fast chain transfer chain, and its main theory of operation does: the roller line support frame plays a role in supporting and fixing the whole roller line working platform, and the ball screw structure is arranged at the bottom of the roller line support frame, and is a common mechanical structure, so detailed description is omitted; the screw rod on the ball screw structure is driven to rotate by the first motor, so that the nut translates left and right on the screw rod, and the nut is fixedly connected with the roller line support frame, so that the roller line support frame can drive the roller line working platform to translate left and right.

The working principle of the left and right transplanting devices is as follows: the left transplanting device and the right transplanting device are used for driving the left side end connecting glue groove and the right side end connecting glue groove to be close to the middle or disperse to the two ends, so that the positions of the left side end connecting glue groove and the right side end connecting glue groove are adjusted, and the working principle is as follows: the third synchronous belt conveying mechanism is used for connecting the first synchronous belt conveying mechanism and the second synchronous belt conveying mechanism, the three synchronous belt conveying mechanisms realize simultaneous operation through a third motor, and the first synchronous belt conveying mechanism and the second synchronous belt conveying mechanism are arranged at the front end and the rear end of the side end glue receiving groove so as to ensure that the front end and the rear end of the side end glue receiving groove are acted by force and ensure the stability of driving force; the synchronous belt on the synchronous belt conveying mechanism is connected with the bottom plate of the side end glue receiving groove through the clamping block, so that the side end glue receiving groove can be driven to move horizontally through the movement of the synchronous belt; the working principle of the front and back transplanting devices is as follows: the effect of front and back transplanting device is to take the tail end to connect the gluey groove translation from beginning to end, and the adjustment position adapts to the size of display screen, and the principle is: through the drive of the second cylinder, the second cylinder drives the moving block to translate on the front and rear translation guide rails, so that the front and rear translation of the tail end glue connecting groove is realized.

The working principle of the clamping mechanism on the glue aging device is as follows: when a product needs to be grabbed, the third cylinder drives the bottom plate to move downwards to be close to the display screen product, then the first panel and the second panel move on respective tracks to move towards the middle to be close to each other, and a row of clamping blocks on the first panel and the second panel respectively clamp the left side and the right side of the product (the moving principle of the first panel and the second panel on the respective tracks is a conventional motor and ball screw transmission structure, and the mechanical structure is a conventional technology in the field, so that the specific description is not provided herein); after the clamping blocks on the two sides clamp the display screen product, the lifting cylinder drives the bottom plate to move upwards, then the clamping and releasing mechanism moves to the position above the heating platform on the parallel tracks, the third cylinder drives the bottom plate to move downwards again, the first panel and the second panel move on the respective tracks to diffuse towards the two sides, so that the clamping blocks on the two sides loosen the display screen product, and the display screen product is separated from the clamping and releasing mechanism and placed on the heating platform to be heated; the moving principle of the moving panel on the parallel tracks is as follows: the gear on the motor output shaft is driven to rotate through the rotation of the fourth motor, and the gear is meshed with the rack fixed on one side of the parallel track, so that the gear can move on the rack while rotating, and the fourth motor and the movable panel are driven to move horizontally on the parallel track.

the first step is as follows: as shown in fig. 1, put the product; the display screen back plate module is placed on the jig plate to ensure that the display screen back plate module is not damaged when being processed on the production line, then the jig plate and the display screen back plate module are placed on the multiple chain conveying line 1 together for conveying, and processing is carried out through a series of equipment;

the second step is that: sticking an adhesive tape; as shown in fig. 3, the periphery of the frame of the display screen backplane module is pasted with the adhesive tape, and the adhesive tape functions to limit the range of the glue, which means that the glue dispenser 3 can only dispense glue in the range of the adhesive tape, so as to ensure that the glue does not overflow to other parts outside the frame of the backplane; rubberizing tape technology is accomplished by operating personnel is manual as auxiliary work, and rubberizing tape platform 2 is operating personnel's work area, and its effect will be at the tool board that 1 removal of multiple chain transfer chain and display screen backplate module temporary transfer to the operating personnel's of both sides work area, and specific theory of operation is: firstly, a first air cylinder 25, the first air cylinder 25 pushes a frame of a tape pasting platform 2, a guide wheel 24 at the bottom of the frame of the tape pasting platform 2 moves on a long rail 23 arranged on a bottom plate 22, the frame drives a roller line working platform to be close to a multiple chain conveying line 1, so that a roller is in butt joint with the multiple chain conveying line 1, a display screen product can be transferred onto the roller line working platform from the multiple chain conveying line 1, then the first air cylinder 25 is controlled to retreat, the frame and the roller line working platform are driven to return to the original positions, an operator carries out tape pasting work, after the work is finished, the first air cylinder 25 is driven to ensure that the roller line working platform is in butt joint with the multiple chain conveying line 1 again, then a driving device drives the roller to rotate, the display screen product is transferred onto the multiple chain conveying line 1, the whole work is finished, and because the tape pasting work possibly takes a long time, four tape pasting platforms 2 are arranged at the, the working efficiency is ensured.

The third step: dispensing; as shown in fig. 5, after the display screen back plate module is pasted with the adhesive tape, the adhesive tape needs to be dispensed, and the operating principle of the dispenser 3 is as follows: after the display screen backboard module moves to the dispensing platform 31 of the dispensing machine 3, the limiting mechanism 14 on the dispensing platform 31 can prevent the display screen backboard from moving forward continuously, then the dispensing tube 32 above the dispensing platform 31 can move under the driving of the three-axis transmission mechanism (the three-axis transmission mechanism is used for driving the dispensing tube 32 to move in the front-back direction of the X axis, the left-right direction of the Y axis and the up-down direction of the Z axis, which belong to the prior art), dispensing is carried out on each part on the display screen backboard module, and meanwhile, in order to adapt to display screens with different sizes, the dispensing machine 3 is further provided with an adaptive width-adapting guide mechanism 33.

The fourth step: scraping glue; as shown in fig. 7, after the display screen backboard module is glued, the glue on the surface of the display screen backboard module needs to be scraped evenly, the glue scraping machine 4 is used for realizing that the working principle of the glue scraping machine 4 is as follows: when the display screen module after dispensing moves onto the glue scraping platform 41 of the glue scraping machine 4, the limiting mechanism 14 on the glue scraping platform 41 can prevent the display screen back plate from continuously moving forwards, the cross beam 42 moves back and forth on the left and right linear rails, and the glue scraping plate 43 is driven to scrape glue on the display screen (the movement of the cross beam 42 on the linear rails utilizes the matching of a driving motor and a traditional ball screw mechanism, and the specific principle is not specifically explained again); the glue receiving grooves 44 at the left side end and the right side end can just receive glue spreading from the side surfaces, when the glue scraping plate 43 moves to the tail end, more glue can be stored at the tail end and can drip along the display screen, and at the moment, the glue receiving grooves 45 at the tail end can just receive the dripping glue, so that no glue can drip on the equipment in the whole process; meanwhile, the two side end glue connecting grooves 44 and the tail end glue connecting groove 45 can respectively realize position adjustment through the left and right transplanting devices and the front and rear transplanting devices, so that the device is suitable for display screens with various sizes.

The fifth step: heating and aging the glue; as shown in fig. 10, after the glue on the surface of the display screen back plate module is uniformly scraped, the glue is water glue, and the setting time of the water glue is long, so when the display screen back plate module is attached to the liquid crystal display screen module, the water glue can easily flow into the liquid crystal display screen to damage a product, and the fixing effect is not obvious, so the water glue needs to be heated and dried, and glue aging equipment is applied to the production line to heat and age the glue on the surface of the display screen back plate module, so that the setting speed of the glue is accelerated; the working principle of the glue aging equipment is as follows: because many glue aging mechanism have been set up altogether, when the display screen backplate module moved the ageing mechanism department of first group glue, the mechanism of putting of clamp down presss from both sides the display screen product from multiple chain transfer chain 1, the rethread parallel guide 52 moves and carries out glue heating ageing on the heating platform 51 of both sides, meanwhile, the display screen product of back can not consequently pause longer time, but can continue to move forward, move to the ageing mechanism department of second group glue and carry out glue ageing, analogize in proper order, can realize that a plurality of display screen products carry out glue heating ageing simultaneously, glue heating ageing time is about 5-8 minutes, after ageing the completion, rethread presss from both sides the mechanism and puts the display screen backplate module and put back on multiple chain transfer chain 1 and continue to carry forward.

And a sixth step: after the glue is aged, the adhesive tape attached to the display screen backboard module needs to be torn off, and the adhesive tape belongs to an auxiliary article and cannot be assembled on the display screen because the work of the adhesive tape is finished; since the structure of the tape tearing platform 6 and the structure of the tape pasting platform 2 are the same, the working principle of the tape tearing platform and the tape pasting platform are also the same, so that repeated description is not provided; simultaneously, the work of tearing the sticky tape is simple some for pasting the sticky tape, so only need in the left and right sides of multiple chain transfer chain 1 set up two tear sticky tape platforms 6 can.

The seventh step: transferring the product; in the step, the display screen back plate module is required to be transferred to overturning and laminating equipment, and the display screen back plate module is required to be laminated with the liquid crystal display screen module; the lifting carrying trolley 7 is used for transferring the display screen back plate module, and the working principle of the trolley is as follows: as shown in fig. 13, the carrying trolley is moved to the tail end of the multiple chain conveying line 1, then the height of the lifting platform 74 is adjusted through the telescopic rod 73, so that the lifting platform 74 is level with the multiple chain conveying line 1, then the display screen backboard module enters the roller 76 of the lifting platform 74 under the guidance of the multiple chain conveying line 1, the display screen integrally enters the lifting platform 74 under the guidance of the roller 76, and then the display screen is conveyed to the turnover bonding equipment through the carrying trolley,
