[0021] The institutional features of the above scheme are explained as follows:

[0022] This scheme designs a display screen module bonding assembly line, and the specific work flow is as follows:

[0023] Step 1: Place the product; place the display back panel module on the jig plate to ensure that it is not damaged during processing on the assembly line, and then place the jig plate together with the display back panel module on the double-speed chain conveyor line for transportation, and then process it through a series of equipment;

[0024] The second step: sticking tape; stick tape around the frame of the display back panel module. The function of the tape is to limit the range of glue, which means that the glue dispenser can only dispense glue within the range of the tape attachment to ensure that the glue will not overflow to other parts outside the back panel frame; the tape sticking process is manually completed by the operator as an auxiliary work, and the tape sticking platform is the operator's working area. Its function is to temporarily transfer the jig plate and the display back panel module moving on the double-speed chain conveyor line to the operator's working area on both sides. The specific working principle is: first, the first cylinder pushes the tape sticking platform rack, and the guide wheel at the bottom of the tape sticking platform rack moves on the long track set on the bottom plate. The rack belt Move the roller line working platform close to the double-speed chain conveyor line to connect the roller and the double-speed chain conveyor line, so that the display screen products can be transferred from the double-speed chain conveyor line to the roller line working platform, and then control the first cylinder to retreat, bringing the frame and the roller line working platform back to their original positions, and the operator performs the tape sticking work. After the work is completed, drive the first cylinder to make the roller line working platform connect with the double-speed chain conveyor line again, and then the driving device drives the roller to rotate, transfer the display screen products to the double-speed chain conveyor line, and complete the whole work. Since the tape sticking work may take a long time, four tape sticking platforms are set on the left and right sides of the double-speed chain conveyor line to ensure work efficiency.

[0025] The third step: glue dispensing; after the display back panel module is affixed with tape, it needs to be glued. The working principle of the glue dispensing machine is as follows: when the display back panel module moves to the glue dispensing platform of the glue dispensing machine, the limit mechanism on the glue dispensing platform will prevent the display back panel from moving forward, and then the glue dispensing tube above the glue dispensing platform will be driven by the three-axis transmission mechanism (the function of the three-axis transmission mechanism is to move the glue dispensing tube in the front and rear directions of the X axis, the left and right directions of the Y axis, and the up and down directions of the Z axis, which belongs to the prior art) to move, and glue is dispensed at various parts of the display back panel module. At the same time, in order to adapt to display screens of different sizes, an adaptive width adjustment guide mechanism is also provided on the glue dispensing machine.

[0026] Step 4: Glue scraping: After the glue is applied to the back panel module of the display screen, the glue on its surface needs to be evenly scraped, which is achieved by a glue scraper. The working principle of the glue scraper is as follows: when the display screen module after glue application moves to the glue scraping platform of the glue scraper, the limit mechanism on the glue scraping platform will prevent the display screen back panel from moving forward, and the crossbeam moves back and forth on the left and right linear tracks, carrying the glue scraper to scrape glue on the display screen (the movement of the crossbeam on the linear track utilizes the cooperation of the drive motor and the traditional ball screw mechanism, and its specific principle will not be explained in detail here). At the same time, when the glue scraper is scraping glue, glue will flow to the left and right sides. To prevent the glue from spreading, a glue receiving groove is provided on the glue scraping platform to catch the spread glue and prevent the glue from dripping on the equipment and causing damage to the equipment; the side glue receiving grooves on the left and right sides can just catch the glue spreading from the sides, and when the scraper moves to the end, more glue will accumulate at the tail end and drip along the display screen. At this time, the tail glue receiving groove can just catch the dripping glue, so no glue will drip onto the equipment during the whole process; at the same time, the two side glue receiving grooves and one tail glue receiving groove can be adjusted in position by the left and right shifting devices and the front and rear shifting devices respectively, so as to adapt to display screens of various sizes.

[0027] Step 5: Glue heating and aging; After the glue on the surface of the display backplane module is evenly scraped, since the glue is water-based glue and the coagulation time of water-based glue is relatively long, when the display backplane module and the LCD display module are attached, the water-based glue can easily flow into the LCD display, causing damage to the product, and the fixing effect is not obvious. Therefore, the water-based glue needs to be heated and dried. The glue aging equipment is used on this assembly line to heat and age the glue on the surface of the display backplane module to accelerate its coagulation speed; the working principle of the glue aging equipment is: since a total of multiple glue aging mechanisms are set up, when the display backplane module moves to the first group of glue When the water aging mechanism is at the site, the clamping and placing mechanism moves downward to clamp the display screen product out from the double-speed chain conveyor line, and then moves it to the heating platforms on both sides through parallel guide rails for glue heating and aging. At the same time, the display screen products behind will not stop for a long time, but will continue to move forward and move to the second set of glue aging mechanisms for glue aging. By analogy, multiple display screen products can be subjected to glue heating and aging at the same time. The glue heating and aging time is about 5 to 8 minutes. After the aging is completed, the display screen back panel module is put back on the double-speed chain conveyor line through the clamping and placing mechanism and continues to be conveyed forward.

[0028] Step 6: After the glue has aged, you need to tear off the tape attached to the display back panel module, because the work of the tape has been completed, and it is an auxiliary product and cannot be assembled on the display; since the structure of the tape tearing platform is the same as that of the tape sticking platform, their working principles are also the same, so they will not be repeated here; at the same time, the work of tearing off the tape is simpler than that of sticking the tape, so only two tape tearing platforms need to be set on the left and right sides of the double-speed chain conveyor line.

[0029] Step 7: Transfer the product; this step requires transferring the display back panel module to the flip bonding equipment and bonding it to the LCD display module; the lifting and transporting trolley is used to transfer the display back panel module. The working principle of the trolley is: first move the transporting trolley to the end of the double-speed chain conveyor line, and then adjust the height of the lifting platform through the telescopic rod to make the lifting platform level with the double-speed chain conveyor line, and then the display back panel module will enter the rollers of the lifting platform under the guidance of the double-speed chain conveyor line, and under the guidance of the rollers, the entire display screen will enter the lifting platform, and then be transported to the flip bonding equipment by the transporting trolley.

[0030] Adjust the telescopic rod again to make the lifting platform and the laminating platform of the flip device level, and then push the display screen from the lifting platform to the laminating platform. The whole process does not require manual handling.

[0031] Step 8: Product bonding; This step is the last step. The display back panel module and the LCD display module are assembled up and down. This is achieved by using a flip laminating machine. The working principle of the flip laminating machine is: first, the front of the upper flip vacuum suction plate is facing up, and the display back panel module is placed on the upper flip vacuum suction plate. The back panel is adsorbed through the vacuum suction holes. After the position of the back panel remains unchanged, the position of the back panel is photographed by the first camera. The first camera transmits the photographed photo to the overall control system of the equipment. After precise analysis by the control system, the glue dispenser is controlled to precisely dispense glue at the set position. (This glue dispenser is used to apply RTV glue to the surface of the backplane module to ensure the bonding effect); the glue dispenser and the first camera move synchronously, which means that the first camera takes a photo and the glue dispenser dispenses glue once; the glue dispenser and the first camera can move forward and backward on the front and rear translation tracks through the first door-type bracket, and realize left and right movement by moving on the first left and right translation tracks on the beam (the movement principle of the glue dispenser and the first camera on the first left and right translation tracks is realized by the common ball screw structure and motor drive, so no specific explanation is given here, and the same is true below). The first camera will record the specific position when taking pictures of the back panel, and the second camera will take pictures of the display screen module placed on the lower bonding platform. The second camera can move forward and backward through the second door-type bracket on the front and rear translation track to achieve forward and backward movement, and move left and right through its own movement on the second left and right translation track on the beam; at the same time, after the back panel is glued, the upper flip vacuum suction plate is controlled to flip over and translate to the top of the display screen module at the same time, and then the control system analyzes the back panel position photos taken by the first camera and the display screen module position photos taken by the second camera respectively, integrates them into data, and performs accurate calculations; after the calculation is completed, the UVW alignment platform located at the bottom of the lower bonding platform is controlled, and the UVW alignment platform can adjust the front and rear position and angle of the display screen module, so that the back panel and the display screen module are aligned up and down, and finally the upper flip vacuum suction plate is driven by the cylinder to translate downward to make the display screen back panel module and the display screen module fit together, completing the process of first gluing, then alignment, and finally bonding.

[0032] The working principle of the adaptive left and right translation mechanism arranged on the tape applying platform and the tape tearing platform is: the main function of the adaptive left and right translation mechanism is to adjust the left and right position of the entire roller line working platform to ensure the precise docking of the roller line working platform and the double-speed chain conveyor line, and its main working principle is: the roller line support frame supports and fixes the entire roller line working platform, and a ball screw structure is arranged at the bottom of the roller line support frame. Since the ball screw structure is a common mechanical structure, it will not be described in detail here; the lead screw on the ball screw structure is rotated by the first motor, so that the nut translates left and right on the lead screw, and the nut is fixedly connected to the roller line support frame, so that the roller line support frame can translate the roller line working platform left and right.

[0033] The working principle of the adaptive width-adjusting guide mechanism is as follows: the adaptive width-adjusting guide mechanism can drive the first transmission shaft to rotate by rotating the second motor according to the size of the display screen and the jig plate. The rotation of the first transmission shaft will cause the belt drive structure arranged at its two ends to operate, and the front and rear parts of the first guide rod and the second guide rod are arranged on the synchronous belts of the two belt drive structures through clamping blocks, which means that the first guide rod and the second guide rod can move together with the synchronous belts, so that the first guide rod and the second guide rod can simultaneously move closer to the middle or spread to both sides at the same time, so as to adjust the width between the two guide rods, so that the two guide rods can be close to the two sides of the jig plate, and at the same time, the guide wheel on the guide rod can make the friction between the guide rod and the jig plate into rolling friction, so that the jig plate and the display screen product can move in a straight line on the conveying mechanism of the dispensing machine, avoiding their position deviation and ensuring the accuracy of dispensing.

[0034] Working principle of left and right transplanting device: The function of left and right transplanting device is to bring the left and right side end glue grooves closer to the middle or disperse to the two ends, so as to adjust their positions. Its working principle is: the third synchronous belt conveying mechanism is used to connect the first synchronous belt conveying mechanism and the second synchronous belt conveying mechanism. The three synchronous belt conveying mechanisms are realized by the third motor to realize simultaneous operation. The first synchronous belt conveying mechanism and the second synchronous belt conveying mechanism are placed at the front and rear ends of the side end glue groove to ensure that the front and rear of the side end glue groove are subjected to force to ensure the stability of the driving force; the synchronous belt on the synchronous belt conveying mechanism is connected to the bottom plate of the side end glue groove through the clamping block, so that the side end glue groove can be translated by the movement of the synchronous belt; Working principle of front and rear transplanting device: The function of front and rear transplanting device is to translate the tail end glue groove forward and backward, and adjust the position to adapt to the size of the display screen. The principle is: driven by the second cylinder, the second cylinder drives the moving block to translate on the front and rear translation guide rails, thereby realizing the front and rear translation of the tail end glue groove.

[0035] The working principle of the clamping mechanism on the glue aging device is: when it is necessary to grab the product, the third cylinder will first drive the bottom plate to move downward close to the display product, and then the first panel and the second panel will move on their respective tracks to get closer to the middle, so that a row of clamping blocks on the first panel and the second panel will clamp the left and right sides of the product respectively (the movement principle of the first panel and the second panel on their respective tracks is a conventional motor with a ball screw transmission structure. This mechanical structure is a conventional technology in this field, so it will not be described in detail here); when the clamping blocks on both sides clamp the display product, the lifting cylinder drives the bottom plate to move upward, and then The clamping mechanism moves on the parallel track to the top of the heating platform, and the third cylinder drives the bottom plate to move downward again. The first panel and the second panel move on their respective tracks and spread to both sides, so that the clamping blocks on both sides release the display screen product, so that the display screen product is separated from the clamping mechanism and placed on the heating platform for heating; the movement principle of the movable panel on the parallel track is: the fourth motor rotates to drive the gear on the motor output shaft to rotate, and the gear is meshed with the rack fixed on one side of the parallel track, so when the gear rotates, it will move on the rack, thereby driving the fourth motor and the movable panel to translate on the parallel track.

[0036] Since the display screen is placed on the lifting platform with rollers at the bottom, it is easy for the display screen to fall off the platform due to inertia during transportation. Therefore, blocks are set on the four sides of the lifting platform to block the display screen and prevent it from falling off the platform. At the same time, in order to ensure that the blocks do not affect the movement of the display screen during the docking process, the blocks are rotatable. During docking, the blocks are turned to a lying state to be level with the lifting platform, which will not affect the transportation of the display screen. When the display screen is completely placed on the platform, the blocks are turned to an upright state to block the display screen and prevent it from falling off the platform.

[0037] The working principle of the flipping and lifting mechanism is: first, a rotating shaft is set on the back of the upper flip vacuum suction plate, and the rotating shaft and the fifth motor are connected by gear meshing, so the rotation of the fifth motor can drive the rotating shaft to rotate, thereby realizing the flipping of the upper flip vacuum suction plate; the up and down lifting of the upper flip vacuum suction plate is realized by the fourth cylinder.

[0038] The working principle of the double-speed chain conveyor line is: by designing two left-right symmetrical chain drive structures, the display screen products are placed on the synchronous chains of the two chain drive structures, and the display screen is driven to move through the movement of the synchronous chains. The driving force of the two chain drive structures is provided by the sixth motor, and the sixth motor and the second transmission shaft are connected by gear meshing. The driving gears of the two chain drive structures are respectively mounted on the left and right ends of the second transmission shaft, so the rotation of the sixth motor can drive the second transmission shaft to rotate, and the rotation of the second transmission shaft drives the driving gears of the two chain drive structures to rotate, thereby making the two chain drive structures operate.

[0039] The beneficial effects of the present invention are as follows: the present invention designs a display screen module bonding assembly line, in which glue dispensing, glue scraping, glue aging and final bonding can all be automatically operated by mechanical equipment, with a high degree of automation and high processing precision, which can meet the requirements of the full bonding process of the display screen, while reducing the fatigue of operators and improving overall work efficiency.

[0072] This scheme designs a display screen module bonding assembly line, and the specific work flow is as follows:

[0073] Step 1: If Figure 1 As shown, place the product; place the display back panel module on the jig plate to ensure that it is not damaged during processing on the assembly line, and then place the jig plate together with the display back panel module on the multiple chain conveyor line 1 for transportation, and then process it through a series of equipment;

[0074] Step 2: Apply tape; Figure 3As shown, tape is pasted around the frame of the display back panel module. The function of the tape is to limit the range of glue, which means that the glue dispenser 3 can only dispense glue within the range of the tape attachment to ensure that the glue will not overflow to other parts outside the back panel frame; the tape application process is manually completed by the operator as an auxiliary work, and the tape application platform 2 is the operator's working area. Its function is to temporarily transfer the jig plate and the display back panel module moving on the multiple chain conveyor line 1 to the operator's working area on both sides. The specific working principle is: first, the first cylinder 25, the first cylinder 25 pushes the frame of the tape application platform 2, and the guide wheel 24 at the bottom of the frame of the tape application platform 2 moves on the long track 23 set on the bottom plate 22, and the frame belt Move the roller line working platform close to the multiple chain conveyor line 1 to connect the roller and the multiple chain conveyor line 1, so that the display screen products can be transferred from the multiple chain conveyor line 1 to the roller line working platform, and then control the first cylinder 25 to retreat, bringing the frame and the roller line working platform back to their original positions, and the operator performs the taping work. After the work is completed, drive the first cylinder 25 to make the roller line working platform and the multiple chain conveyor line 1 dock again, and then the driving device drives the roller to rotate, and transfer the display screen products to the multiple chain conveyor line 1 to complete the entire work. Since the taping work may take a long time, four taping platforms 2 are set on the left and right sides of the multiple chain conveyor line 1 to ensure work efficiency.

[0075] Step 3: Glue dispensing; Figure 5 As shown, after the display screen back panel module is affixed with tape, it needs to be glued. The working principle of the glue dispensing machine 3 is as follows: when the display screen back panel module moves to the glue dispensing platform 31 of the glue dispensing machine 3, the limiting mechanism 14 on the glue dispensing platform 31 will prevent the display screen back panel from continuing to move forward, and then the glue dispensing tube 32 above the glue dispensing platform 31 will be driven by the three-axis transmission mechanism (the function of the three-axis transmission mechanism is to move the glue dispensing tube 32 in the front and rear directions of the X-axis, the left and right directions of the Y-axis, and the up and down directions of the Z-axis, which belongs to the prior art) to move, and glue is dispensed at various parts of the display screen back panel module. At the same time, in order to adapt to display screens of different sizes, an adaptive width adjustment guide mechanism 33 is also provided on the glue dispensing machine 3.

[0076] Step 4: scrape glue; Figure 7As shown, after the glue is applied to the back panel module of the display screen, the glue on its surface needs to be evenly scraped, which is achieved by a glue scraper 4. The working principle of the glue scraper 4 is as follows: when the display screen module after glue application moves to the glue scraping platform 41 of the glue scraper 4, the limit mechanism 14 on the glue scraping platform 41 will prevent the display screen back panel from continuing to move forward, and the crossbeam 42 moves back and forth on the left and right linear tracks, carrying the glue scraper 43 to scrape glue on the display screen (the movement of the crossbeam 42 on the linear track utilizes the cooperation of the driving motor and the traditional ball screw mechanism, and its specific principle will not be described in detail here). At the same time, when the glue scraper 43 is scraping glue, glue will flow to the left and right sides. To prevent the glue from spreading to the side, a glue receiving groove is provided on the glue scraping platform 41 to catch the glue spreading down and prevent the glue from dripping onto the equipment and causing damage to the equipment; the side end glue receiving grooves 44 on the left and right sides can just catch the glue spreading down from the side, and when the scraper plate 43 moves to the end, more glue will accumulate at the tail end and drip along the display screen. At this time, the tail end glue receiving groove 45 can just catch the dripping glue, so no glue will drip onto the equipment during the whole process; at the same time, the two side end glue receiving grooves 44 and one tail end glue receiving groove 45 can be respectively adjusted in position by the left and right shifting devices and the front and rear shifting devices, so as to adapt to display screens of various sizes.

[0077] Step 5: Glue heating aging; Fig.10 As shown in the figure, after the glue on the surface of the display back panel module is evenly scraped, since the glue is water-based glue and the coagulation time of water-based glue is relatively long, when the display back panel module and the LCD display module are attached, the water-based glue can easily flow into the LCD display, causing damage to the product, and the fixing effect is not obvious. Therefore, the water-based glue needs to be heated and dried. The glue aging equipment is used on this production line to heat and age the glue on the surface of the display back panel module to accelerate its coagulation speed. The working principle of the glue aging equipment is as follows: Since a total of multiple glue aging mechanisms are set up, when the display back panel module moves to the first group of glue aging mechanisms, The clamping mechanism moves downward to clamp the display screen product out of the multiple chain conveyor line 1, and then moves it to the heating platforms 51 on both sides through the parallel guide rails 52 for glue heating and aging. At the same time, the display screen products behind will not stop for a long time, but will continue to move forward and move to the second group of glue aging mechanisms for glue aging. By analogy, multiple display screen products can be subjected to glue heating and aging at the same time. The glue heating and aging time is about 5-8 minutes. After the aging is completed, the display screen back panel module is put back on the multiple chain conveyor line 1 through the clamping mechanism and continues to be conveyed forward.

[0078] Step 6: After the glue is aged, the tape attached to the display back panel module needs to be torn off, because the work of the tape has been completed, and it is an auxiliary product and cannot be assembled on the display; since the structure of the tape tearing platform 6 is the same as that of the tape sticking platform 2, their working principles are also the same, so they will not be repeated here; at the same time, the work of tearing tape is simpler than that of sticking tape, so only two tape tearing platforms 6 need to be set on the left and right sides of the multiple chain conveyor line 1.

[0079] Step 7: Transfer the product; in this step, the display back panel module needs to be transferred to the flip bonding device and bonded to the LCD display module; the lifting and transporting trolley 7 is used to transfer the display back panel module, and the working principle of the trolley is as follows: Fig.13 As shown, first move the transport trolley to the end of the multiple chain conveyor line 1, then adjust the height of the lifting platform 74 through the telescopic rod 73, so that the lifting platform 74 is level with the multiple chain conveyor line 1, and then the display back panel module will enter the roller 76 of the lifting platform 74 under the guidance of the multiple chain conveyor line 1, and the display screen will enter the lifting platform 74 as a whole under the guidance of the roller 76, and then be transported to the flipping and bonding equipment by the transport trolley.

[0080] The telescopic rod 73 is adjusted again to make the lifting platform 74 and the fitting platform of the flip device level, and then the display screen is pushed from the lifting platform 74 to the fitting platform. The whole process does not require manual handling.

[0081] Step 8: Product bonding; this step is the last step, such as Fig.14As shown, the display screen back panel module and the liquid crystal display screen module are assembled up and down by using a flip laminating machine 8. The working principle of the flip laminating machine 8 is as follows: first, the front side of the upper flip vacuum suction plate 82 is facing upward, and the display screen back panel module is placed on the upper flip vacuum suction plate 82. The back panel is adsorbed by the vacuum suction holes. After the position of the back panel remains unchanged, the position of the back panel is photographed by the first camera 89. The first camera 89 transmits the photographed photo to the control system of the entire device. After accurate analysis by the control system, the glue dispenser 88 is controlled to accurately dispense glue at the set position (this glue dispenser 88 is for the back panel module surface RTV glue is applied on the surface to ensure the fitting effect); the glue dispenser 88 and the first camera 89 move synchronously, which means that the first camera 89 takes a photo and the glue dispenser 88 dispenses glue once; the glue dispenser 88 and the first camera 89 can move forward and backward on the front and rear translation tracks through the first door-type bracket 86, and realize left and right movement by moving on the first left and right translation tracks on the beam 42 (the movement principle of the glue dispenser 88 and the first camera 89 on the first left and right translation tracks is realized by the common ball screw structure 27 in conjunction with the motor drive, so it will not be explained in detail here, and the same applies to the following text). The first camera 89 will record the specific position when taking pictures of the back plate, and the second camera 810 will take pictures of the display screen module placed on the lower bonding platform 83. The second camera 810 can move forward and backward through the second door-shaped bracket 87 on the front and rear translation track to achieve forward and backward movement, and move left and right through its own movement on the second left and right translation track on the beam 42; at the same time, after the back plate is glued, the upper flip vacuum suction plate 82 is controlled to flip over and translate to the top of the display screen module at the same time, and then the control system analyzes the back plate position photos taken by the first camera 89 and the display screen module position photos taken by the second camera 810 respectively, integrates them into data, and performs accurate calculations; after the calculation is completed, the UVW alignment platform located at the bottom of the lower bonding platform 83 is controlled, and the UVW alignment platform can adjust the front and rear position and angle of the display screen module, so that the back plate and the display screen module are aligned up and down, and finally the upper flip vacuum suction plate 82 is driven by the cylinder to translate downward to make the display screen back plate module and the display screen module fit together, completing the process of first gluing, then alignment, and finally bonding.

[0082] The preferred implementation is as follows:

[0083] like Figure 4As shown, the tape applying platform 2 and the tape tearing platform 6 are also provided with an adaptive left-right translation mechanism, which includes a ball screw structure 27, a first motor 28 and a roller line support frame 5329; the ball screw structure 27 includes a screw rod and a nut, the motor is connected to the screw rod through a coupling, the nut is sleeved on the screw rod, and the nut is fixedly connected to the bottom of the roller line support frame 29; the working principle of the adaptive left-right translation mechanism provided on the tape applying platform 2 and the tape tearing platform 6 is as follows: the main function of the adaptive left-right translation mechanism is to adjust the left-right position of the entire roller line working platform to ensure that the roller The line working platform and the multiple chain conveyor line 1 are precisely docked, and its main working principle is: the roller line support frame 29 supports and fixes the entire roller line working platform, and a ball screw structure 27 is arranged at the bottom of the roller line support frame 29. Since the ball screw structure 27 is a common mechanical structure, it will not be described in detail here; the screw rod on the ball screw structure 27 is rotated by the first motor 28, so that the nut is translated left and right on the screw rod, and the nut is fixedly connected to the roller line support frame 29, so that the roller line support frame 29 can translate the roller line working platform left and right.

The rotation of the first transmission shaft 38 will cause the belt drive structure 39 arranged at both ends thereof to operate, and the front and rear parts of the first guide rod 34 and the second guide rod 35 are arranged on the synchronous belts of the two belt drive structures 39 through clamping blocks, which means that the first guide rod 34 and the second guide rod 35 can move together with the synchronous belt, so that the first guide rod 34 and the second guide rod 35 are simultaneously moved closer to the middle or spread to both sides at the same time, so as to adjust the width between the two guide rods, so that the two guide rods can be close to the two sides of the fixture plate, and at the same time, the guide wheel 36 on the guide rod can make the friction between the guide rod and the fixture plate into rolling friction, so that the fixture plate and the display screen product can move in a straight line on the conveying mechanism of the dispensing machine 3, avoiding their position deviation and ensuring the accuracy of dispensing.

Belt; Working principle of left and right transplanting device: The function of left and right transplanting device is to bring the left and right side end glue grooves 44 closer to the middle or disperse to the two ends, so as to adjust their positions. Its working principle is: the third synchronous belt conveying mechanism 48 is used to connect the first synchronous belt conveying mechanism 46 and the second synchronous belt conveying mechanism 47. The three synchronous belt conveying mechanisms are realized by the third motor 49 to realize simultaneous operation. The first synchronous belt conveying mechanism 46 and the second synchronous belt conveying mechanism 47 are placed at the front and rear ends of the side end glue groove 44 to ensure that the front and rear of the side end glue groove 44 are subjected to force to ensure the stability of the driving force; the synchronous belt on the synchronous belt conveying mechanism is connected to the bottom plate 22 of the side end glue groove 44 through the clamping block, so that the side end glue groove 44 can be translated by the movement of the synchronous belt;
