Description

Technical Field

[0001] This invention belongs to the technical field of visual positioning adjustment equipment. Specifically, it relates to an improvement of a visual positioning adjustment device for upper and lower molds and a visual positioning adjustment method using the device. Background Technology

[0002] Existing displays for external display functions include, in addition to the display body, LED light board modules constituting the display and an aluminum frame connected to and supporting the light board modules. The LED light board module includes multiple light boards, and in the structural design, the multiple light boards need to be spliced ​​together and cured with the aluminum frame using UV curing adhesive to form an integral structure.

[0003] The aluminum frame and the light panel are cured on the lower template. First, the light panel is placed on the lower template, and then the aluminum frame is placed in place. UV curing adhesive is applied to the corresponding mating positions of the light panel and the aluminum frame. After the light panel is in place, a curing lamp is used to cure the adhesive so that the light panel and the aluminum frame are bonded together.

[0004] Currently, the main method for feeding light panels is manual. Positioning components are set around the light panel placement position on the lower template. These positioning components can be positioning cylinder lights. After the light panel is placed in the placement position, it is simply adjusted manually so that the side of the light panel is basically in contact with the positioning component. Then, the aluminum frame is lowered manually. Place a curing lamp on the side of the lower template at a certain distance. During curing, the curing lamp can be used to heat and cure the adhesive on the lamp plate. After curing, place the molded product on the testing equipment for accuracy testing.

[0005] The entire loading of the light panel and aluminum frame is done manually, resulting in low production efficiency. In addition, the positioning of the lamp board is mainly done by a few positioning parts for rough positioning, which results in poor positioning accuracy. Furthermore, the lamp board may be deformed during curing, ultimately leading to poor precision of the finished product, which cannot meet the usage requirements and requires rework and reprocessing, resulting in a high defect rate and rework rate.

[0006] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Summary of the Invention

The controller establishes a product coordinate system based on the coordinate positions of the two markers. The product coordinate system has an X-axis and a Y-axis, and the marker line extends along the Y-axis. The controller controls the lower mold moving module to move the lower mold vision component, take pictures of the marking points on the light board to obtain the coordinate position of each marking point in the machine reference coordinate system, and the lower mold vision component transmits the coordinate position of each marking point to the controller. The controller calculates and obtains the actual coordinate position of the marker point in the product coordinate system based on the position of the marker point in the machine reference coordinate system and the coordinate position of the product coordinate system. The deflection angle of the light panel is determined by the angle between the marker line formed by connecting the actual coordinates of multiple marker points and the Y-axis. The offset value of the marker point is obtained by comparing its actual coordinate position with the reference coordinate position stored in the controller, and the adjustment module is controlled to operate based on the deflection angle and the offset value.

[0016] In some embodiments of this application, determining the deflection angle of the light panel specifically includes the following steps: Check whether the indicator line and the Y-axis are within the preset angle range. If so, it means that the light panel has not deflected.

[0017] If the angle between the two is not within the preset angle range, it means that the light panel is deflected. The angle value that the lamp panel needs to be adjusted is obtained based on the detected included angle and the upper or lower limit angle value of the preset angle range. The rotation module is then controlled to drive the lamp panel to rotate for adjustment. After determining the deflection angle of the light panel, it is then determined whether the light panel has shifted in the X or Y direction. The difference between the actual X value and the reference X value of the two identified points was detected to be within the first preset deviation range; If the difference between the actual Y value and the reference Y value of the two marker points is not within the second preset deviation range, it means that the light panel has shifted in the Y direction; The control three-way movement module drives the light panel pickup component to adsorb the light panel and move it along the Y-axis direction to adjust its position. When the difference between the actual X value and the reference X value of two identified points is not within the first preset deviation range; The difference between the actual Y value and the reference Y value of the two marker points is within the second preset deviation range, which means that the light panel has shifted in the X direction; The control three-way movement module drives the lamp board pickup component to adsorb the lamp board and move it along the X-axis direction to adjust its position.

[0018] Compared with the prior art, the advantages and positive effects of the present invention are: When the upper and lower mold visual positioning and adjustment device of the present invention is in use, it can establish a product coordinate system and accurately detect the actual position of the light board by cooperating with the upper mold visual component on the upper mold and the lower mold visual component on the lower mold. When a deviation in the position of the light board is detected, the position of the light board can be automatically adjusted by the adjustment module, thereby realizing automated measurement and adjustment and improving the overall production efficiency. When the three-way moving module or rotating module drives the light panel to move and adjust, it moves by a preset distance and rotates by a preset angle. After moving the preset distance, the lower mold vision component takes another picture to obtain the position of the mark point in the product coordinate system. If there is still a deviation, it is adjusted again.

[0019] By adjusting and taking multiple photos for recognition, high-precision adjustment of the light board can be ensured, guaranteeing the accuracy of the light board position, improving the overall molding accuracy of the product, and thus reducing the defect rate and rework rate.

[0028] In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0029] This invention proposes an embodiment of a visual positioning and adjustment device for upper and lower molds, comprising: The lower mold module 100 includes a lower mold support platform 110, on which a lamp plate placement position 120 for placing multiple lamp plates 900 is formed. In some embodiments of this application, the lower mold support platform 110 is a lower mold support plate, which is used to place the lamp plate 900.

[0030] To increase the friction between the lamp plate 900 and the lower mold support plate and ensure the stability of the lamp plate 900 when placed on the lower mold support platform 110, a rubber-coated surface is provided at the placement position of the lower mold support platform 110.

[0031] The upper and lower mold visual positioning adjustment device in this embodiment is mainly used to place multiple light panels 900 at multiple light panel placement positions 120 on the lower mold support plate. By adjusting the position of the light panels 900, the multiple light panels 900 are assembled into an integral light panel 900 module, and assembled together with the aluminum frame 800 to form a complete structure.

[0032] The light panel 900 and the aluminum frame 800 are fixed together with a curing adhesive to form part of the overall display screen structure.

[0033] Each light panel 900 has a marker point 910 at its bottom. There are at least two marker points 910, and the two marker points 910 are collinear. The position of the light panel 900 can be obtained by the position of the marker points 910, and the position of the light panel 900 can be adjusted.

[0034] To facilitate the acquisition of the position of the marker point 910 on the light panel 900, through holes are provided on the lower mold support plate at the corresponding positions of the marker point 910 on the light panel 900.

[0035] and a lower mold vision module, the lower mold vision module including: The lower mold moving module 200 and the lower mold vision component 230 connected to the lower mold moving module 200; The lower mold vision component 230 can move under the drive of the lower mold moving module 200 to take pictures of the marking point 910 of the light panel 900 placed on the lower mold support platform 110; The lower mold moving module 200 is a bidirectional moving module that can move in the X and Y directions. It is connected to the lower mold vision component 230 and can drive the lower mold vision component 230 to move along the X and Y directions to capture the marking point 910 on the light panel 900.

[0036] In some embodiments of this application, the lower mold vision component 230 is a lower mold industrial camera, which includes an industrial camera body and a lens connected to the industrial camera body.

[0037] The industrial camera can be a direct application of existing industrial cameras, which can obtain the coordinate position of the marker 910 in the machine coordinate system of the equipment itself by directly photographing the marker 910.

[0038] The upper mold module 300 is positioned above the lower mold module 100 and includes: The upper mold vision component 310 is used to obtain the coordinate position of the marker 810 by photographing the marker 810 on the aluminum frame; In some embodiments of this application, the upper mold vision component 310 is an upper mold industrial camera, which can also directly obtain the coordinate position of the marker 810 in the machine coordinate system by taking a picture of the marker 810.

[0039] The adjustment module is mainly used to adjust the position of the lamp panel 900. There are multiple light panels 900, and there are also multiple sets of adjustment modules. The positions of the multiple light panels 900 on the lower mold support platform 110 can be adjusted individually through the multiple sets of adjustment modules.

[0040] When the light panel 900 is placed on the lower mold support platform 110, the position of each light panel 900 is different. Multiple sets of adjustment modules can be set separately to adjust the position of each light panel 900 individually, which not only ensures the adjustment accuracy of the light panel 900, but also greatly improves the adjustment efficiency of the light panel 900.

[0041] Each set of adjustment modules includes: a three-way movement module 320, which can move in the X, Y and Z directions; In some embodiments of this application, the three-way movement module 320 includes an X-axis movement module; And a Y-axis moving module connected to the X-axis moving module, and a Z-axis moving module connected to the Y-axis moving module. The X-axis moving module, Y-axis moving module, and Z-axis moving module are based on the existing linear screw and nut module structure.

[0042] The rotating module 330, which is connected to the three-way moving module 320, is capable of moving in three directions under the drive of the three-way moving module 320; The rotation module 330 includes a rotation motor, which is connected to the Z-axis movement module.

[0043] The three-way movement module 320 can drive the rotation module 330 to move in the X, Y, and Z directions.

[0044] The lamp model pickup module includes a lamp board pickup carrier 340 and a lamp board pickup component 350.

[0045] A lamp board pickup carrier 340 is connected to the bottom of the rotating module 330, and a lamp board pickup component 350 is provided on the lamp board pickup carrier 340. In some embodiments of this application, the lamp board pickup carrier 340 is a lamp board 900 pickup carrier plate, and the lamp board pickup component 350 is a lamp board 900 pickup nozzle, which is assembled and fixed on the lamp board pickup carrier 340.

[0046] When the position of the lamp panel 900 needs to be adjusted, the three-way moving module 320 can drive the rotating module 330 and the lamp panel picking component 350 to move downwards. When they move to a position close to the lamp panel 900, the lamp panel 900 is attracted by the lamp panel picking component 350.

[0047] The position of the lamp board 900 is adjusted by moving or rotating the lamp board pickup component 350 and the lamp board 900 in the X, Y, or Z directions via the three-way moving module 320.

[0048] The light board 900 pickup suction device is floating relative to the light board pickup carrier 340, so that it can maintain flexible contact with the light board 900 when it moves down to contact the light board 900, avoiding damage to the light board 900 caused by hard contact.

[0049] The pressing component 410 is arranged on the lamp plate pickup carrier 340, and can be moved down and pressed onto the lamp plate 900 by the three-way moving module 320 to position the lamp plate 900 when the upper mold vision component 310 takes a picture. In some embodiments of this application, the pressing component 410 is a pressing pin, which is mounted on the light board pickup carrier 340 and can be pressed onto the light board 900 to position the light board 900 when the upper mold vision component 310 takes pictures, so as to ensure the accuracy of the upper mold vision component 310 taking pictures.

[0050] In some embodiments of this application, multiple pressing components 410 are provided and arranged along the four edges of the lamp panel pickup carrier 340. The outline shape and size of the lamp panel pickup carrier 340 are the same as those of the lamp panel 900. The pressing components 410 are arranged around the lamp panel pickup carrier 340 to ensure that they can be pressed down at the four edges of the lamp panel 900 when pressed down, thereby ensuring the firmness of pressing and positioning the lamp panel 900.

[0051] The controller communicates with the lower mold vision component 230 and the upper mold vision component 310. It can establish a product coordinate system based on the position of the marker 810 on the aluminum frame 800 captured by the upper mold vision component 310, and obtain the position deviation value of the light panel 900 based on the position of the marker point 910 captured by the lower mold vision component 230 in the product coordinate system. The adjustment module is controlled to adjust the position of the lamp panel 900 based on the position deviation value.

[0052] Specifically, when establishing the product coordinate system, two markers 810 are set on the aluminum frame 800. The Y-axis is formed by the connecting line between the two markers 810, and the X-axis is formed by drawing a perpendicular line to one of the markers 810, so as to establish the product coordinate system.

[0053] The position of the marker point 910 in the machine coordinate system can be obtained through the lower mold vision component 230. The controller can calculate and analyze the actual position of the marker point 910 in the product coordinate system based on the machine coordinate position of the marker point 910 and the position of the product coordinate system formed by it.

[0054] Each light panel 900 has two marker points 910, which can form a marker line. After obtaining the actual position of the two marker points 910 in the product coordinate system, it can be compared with the reference coordinate position of the two marker points 910 pre-stored in the controller to obtain the position deviation value of the two marker points 910. When the position deviation value is obtained, the adjustment module can be controlled to make adjustments.

[0055] For example, when the lamp panel 900 is offset in the X direction, the three-way movement module 320 can be controlled to drive the lamp panel pickup component 350 to move in the X direction. When the lamp panel 900 is offset in the Y direction, the three-way movement module 320 can be controlled to drive the lamp panel pickup component 350 to move in the Y direction. When the lamp panel 900 has a certain angle of deflection, the rotation module 330 can be controlled to drive the lamp panel pickup component 350 to rotate to correct the offset.

[0056] In this embodiment, the upper and lower mold visual positioning and adjustment device can establish a product coordinate system and accurately detect the actual position of the light board 900 by cooperating with the upper mold visual component 310 on the upper mold and the lower mold visual component 230 on the lower mold. When a deviation is detected in the position of the light board 900, the position of the light board 900 can be automatically adjusted by the adjustment module, realizing automated measurement and adjustment and improving the overall production efficiency. When the three-way moving module 320 or the rotating module 330 drives the light panel 900 to move and adjust, the movement is at a preset distance and the rotation is at a preset angle. After moving the preset distance, the lower mold vision component 230 takes another picture to obtain the position of the marker point 910 in the product coordinate system. If there is still a deviation, it is adjusted again.

[0057] By adjusting and taking multiple photos for recognition, high-precision adjustment of the light board 900 can be ensured, guaranteeing the accuracy of the light board 900's position, improving the overall molding accuracy of the product, and thus reducing the defect rate and rework rate.

[0058] In some embodiments of this application, the upper mold module 300 further includes an aluminum frame picking module 360, which is used to pick up the aluminum frame 800 conveyed by the bidirectional conveyor line, so as to transport the aluminum frame 800 onto the lamp plate 900 located above the lower mold support plate, so as to connect and fix it with the lamp plate 900.

[0059] The aluminum frame 800 can be automatically picked up by the aluminum frame picking component 363, realizing the automated feeding of the aluminum frame 800.

[0060] In some embodiments of this application, the aluminum frame pickup module 360 ​​includes: Vertical movement module 361; A connecting frame 362, on which a plurality of receiving portions 3621 are formed for accommodating the Z-axis moving module of the rotating module 330 and the three-axis moving module 320; In some embodiments of this application, the connecting frame 362 includes multiple connecting plates, the ends of which are joined together to form multiple receiving portions 3621, which are receiving spaces.

[0061] The Z-axis moving module and the rotation module 330 of the three-way moving module 320 are vertically arranged in the receiving part 3621 to reduce the overall space occupied.

[0062] And a pick-up component 363 connected to the bottom of the connecting frame 362, wherein a magnetic attracting component is embedded at the bottom of the aluminum frame pick-up component 363 for attracting the aluminum frame 800; A retractable clamping element is provided around the aluminum frame picking member 363. The clamping element includes a clamping cylinder and a clamping plate, and the end of the clamping plate is provided with a clamping slope.

[0063] When set up, the aluminum frame pickup component 363 is an aluminum frame pickup plate, and its shape and size are the same as the outer dimensions of the aluminum frame 800. A corresponding magnetic attraction component is set on the aluminum frame 800 at the position corresponding to the magnetic attraction component.

[0064] The attracting element can be a magnetic element or a metal element.

[0065] When the vertical moving module 361 moves downward, it can drive the connecting frame 362 and the aluminum frame picking component 363 located below it to move downward, thereby picking up the aluminum frame 800 through the magnetic attraction component, and simultaneously clamping the aluminum frame 800 around its perimeter through the clamping component, and then the aluminum frame 800 can be transported.

[0066] To minimize the space occupied by the entire device, the aluminum frame pickup component is positioned below the lamp panel pickup carrier 340 during installation. An avoidance portion is provided on the aluminum frame pickup component 363 to avoid the pressing component 410 and the lamp panel pickup component 350 so that both extend out of the aluminum frame pickup component 363. The clearance part is a clearance hole so that when the three-way moving module 320 drives the lamp board 900 to move in the Z direction, the lamp board picking member 350 and the pressing member 410 can move downward relative to the aluminum frame picking member 363 without being interfered with by the aluminum frame picking member 363.

[0067] Among them, the Z-axis movement module and the vertical movement module 361 of the adjustment module move synchronously.

[0068] To prevent the lamp panel pickup component 350 from touching the aluminum frame pickup component 363 and being limited after moving a certain distance during the Z-axis movement of the adjustment module, or to prevent the aluminum frame pickup component 363 from being limited and interfered with by the lamp panel pickup component 350 during the upward movement driven by the vertical movement module 361, the Z-axis movement module and the vertical movement module 361 are set to move synchronously, ensuring the normal operation of both.

[0069] In some embodiments of this application, a clamping and positioning assembly is provided on the lower mold support platform 110, including a plurality of clamping and positioning components 420, which are used to clamp the aluminum frame 800 after the aluminum frame picking module 360 ​​places the aluminum frame 800 in place so that the aluminum frame picking component 363 and the aluminum frame 800 are separated.

[0070] The clamping and positioning component 420 consists of a clamping and positioning cylinder and a clamping and positioning block connected to the end of the clamping and positioning cylinder. An inclined clamping and positioning slope is provided at the end of the clamping and positioning block.

[0071] When the vertical moving module 361 moves the aluminum frame picking component 363 downward to the lower mold support platform 110, multiple pressing and positioning cylinders can control the pressing and positioning blocks connected to them to extend out, and press and position the aluminum frame 800 at the side position of the aluminum frame 800 through the pressing and positioning inclined surface.

[0072] After the clamping and positioning component 420 clamps and positions the aluminum frame 800, the clamping component can be controlled to retract. The vertical moving module 361 moves, causing the aluminum frame picking component 363 and the clamping component to move upward. Since the aluminum frame 800 is clamped and fixed by the clamping and positioning component 420, as the aluminum frame picking component 363 moves upward, it can overcome the magnetic force between the magnetic attraction component of the aluminum frame 800 picking component and the aluminum frame 800, and finally the two separate.

[0073] In some embodiments of this application, the vertical movement module 361 includes: A vertically movable base 3611, on both sides of which the upper mold vision component 310 is provided; The upper mold vision components 310 on both sides of the vertically movable base 3611 can be used to photograph the two pins on the aluminum frame 800 respectively.

[0074] And a vertical linear transmission module 3612, which is mounted on the vertical moving base 3611; The vertical linear transmission module 3612 can be a motor lead screw and nut transmission module structure.

[0075] Two vertical sliding components 3613 are provided and arranged on both sides of the vertical moving base 3611. They are connected to the vertical linear transmission module 3612 and move upward under the drive of the vertical linear transmission module 3612. A sliding track is provided on the vertical moving base 3611, and the vertical sliding component 3613 can slide up and down along the sliding track.

[0076] The supporting and limiting member 3614 is horizontally connected between the two vertical sliding members 3613 and connected to the connecting frame 362; In some embodiments of this application, the supporting and limiting member 3614 is a supporting and limiting plate, which is fixedly connected to the two vertical sliding members 3613.

[0077] When the vertical sliding component 3613 slides, it can slide up and down, thereby causing the connecting frame 362 connected to it and the aluminum frame pickup component 363 connected to the connecting frame 362 to slide up and down.

[0078] After the vertical sliding component 3613 slides upward to a certain position, it can be limited by the supporting and limiting component 3614 against the vertical moving base 3611.

[0079] The counterweight module 365 is connected to the supporting and limiting member 3614.

[0080] To ensure the stability of the aluminum frame 800 as it moves downwards, the aluminum frame picking component 363 is connected to a counterweight module 365 on the supporting and limiting component 3614.

[0081] Furthermore, since the aluminum frame pickup component 363 needs to be rigidly moved upward by the vertical moving module 361 to overcome the magnetic attraction between the pickup component and the aluminum frame 800 when it is separated from the aluminum frame 800, the vertical moving module 361 may deviate in the accuracy of the Z-direction due to the force during the upward pulling process. The counterweight module 365 ensures the stability of the overall structure of the vertical moving module 361, the connecting frame 362 and the aluminum frame pickup component 363, avoids the displacement in the Z-direction due to the force, and ensures the accuracy of the Z-direction movement.

[0082] To ensure the parallelism of the aluminum frame 800 and the lamp in the vertical direction, relevant adjustments were made during the initial assembly of the equipment in this embodiment. The upper and lower molds were adjusted to be parallel using a professional fixture so that the bottom surface of the aluminum frame picking component 363 of the upper mold module 300 and the top surface of the lower mold support platform 110 are basically parallel.

[0083] Therefore, as long as the aluminum frame 800 picked up by the aluminum frame picking component 363 ensures the accuracy of its movement in the Z direction, the top surface of the aluminum frame 800 placed on the lamp plate 900 and the bottom surface of the lamp plate 900 can be kept basically parallel, and their parallelism is within the preset tolerance range.

[0084] In this embodiment, the counterweight module 365 ensures the Z-axis movement accuracy of the aluminum frame pickup module 360, thereby ensuring the parallelism between the aluminum frame 800 and the lamp panel 900.

[0085] To detect the parallelism between the aluminum frame 800 and the lamp panel 900, a laser detection assembly is provided on the lower mold support platform 110. The assembly includes multiple laser detection elements arranged circumferentially along the lower mold support platform 110. These elements can emit laser lines to the bottom surface of the aluminum frame pickup member 363 to detect the distance from each position of the aluminum frame pickup member 363 to the lower mold support platform 110.

[0086] The laser detection element is a laser emitter. The emitted point laser shines on the bottom surface of the aluminum frame pickup component 363 to measure the distance from the bottom surface of the aluminum frame pickup component 363 to the lower mold support platform 110.

[0087] Since multiple laser emitters are set up in different locations, when all laser emitters measure similar distances, it means that the two are parallel; otherwise, an alarm will be triggered.

[0088] In some embodiments of this application, the counterweight module 365 includes: The counterweight box 3651 and the counterweight block 3652 are slidably disposed in the counterweight box 3651. The counterweight block 3652 is connected to the supporting and limiting member 3614 by a belt 3653.

[0089] In some embodiments of this application, to achieve curing of the adhesive on the light panel 900, the upper and lower mold visual positioning adjustment device further includes: Curing lamps 500 are installed at the bottom of the aluminum frame pickup component 363. Multiple lamps are installed and evenly distributed on the aluminum frame pickup component 363. The vertical moving module 361 can drive the aluminum frame picking component 363 to move down to cure the adhesive on the lamp panel 900. Before the vertical moving module 361 moves down, the adjustment module can drive the pressing component 410 on the lamp panel picking carrier 340 to move down to press and position the lamp panel 900.

[0090] After the lamp panel 900 is adjusted to the correct position, the aluminum frame picking component 363 can be controlled to move downwards, causing the aluminum frame 800 to press onto the lamp panel 900. After the aluminum frame 800 is pressed onto the lamp panel 900, the vertical movement module 361 is controlled to move the aluminum frame 800 to pick up the component and maintain this position. Then, the controller controls the curing lamp 500 to turn on, and the curing lamp 500 emits heat to cure the adhesive.

[0091] To prevent the curing lamp 500 from burning out, during use, the curing lamp 500 can be turned on for a first preset time and then turned off, and then turned on again after a second preset time. By repeatedly turning it on and off, the curing adhesive can be heated and cured.

[0092] To prevent the curing adhesive from deforming and causing the position of the lamp plate 900 to change due to the heat generated by the curing lamp 500, the pressing component 410 is moved down before curing to press and fix the lamp plate 900 around its perimeter. This ensures the positional accuracy of the lamp plate 900 after curing, and thus ensures the overall accuracy of the molded product.

[0093] In some embodiments of this application, a heat dissipation module for cooling the curing lamp 500 is also included, the heat dissipation module comprising: The air blowing device includes an air source: A blowing pipe 610 connected to and connected to a gas source, the blowing pipe 610 having a blowing component facing the curing lamp 500; An air intake device, used to draw in the airflow passing through the curing lamp 500, includes: The intake housing 620 has an airflow cavity formed inside it; And an air intake fan 630 embedded in the air intake housing 620, an air intake part is provided on the air intake housing 620 at a position corresponding to the air intake fan 630, and the air intake part is connected to the airflow cavity; The exhaust component is connected to the airflow cavity.

[0094] In some embodiments of this application, the blowing component is a blowing nozzle, which includes multiple blowing channels. The airflow introduced from the air source into the blowing pipe 610 can be blown through the multiple blowing channels on the blowing nozzle to the curing lamp 500 located on the aluminum frame pickup component 363. The airflow passing through the curing lamp 500 can carry away the heat generated by the curing lamp 500, thereby preventing the curing lamp 500 from being damaged due to excessively high temperature, and achieving the cooling effect of the curing lamp 500.

[0095] The suction fan 630 is positioned towards the curing lamp 500. The hot airflow passing through the curing lamp 500 is drawn into the suction housing 620 by the suction fan 630, and then discharged from the exhaust component after passing through the airflow chamber in the suction housing 620.

[0096] The combination of the blowing and suction devices allows airflow to quickly pass through the curing lamp 500, carrying away the heat from the curing lamp 500 and thus preventing it from burning out due to overheating.

[0097] In some embodiments of this application, the lower mold module 100 further includes: The lower mold base 130 has an installation space formed at its bottom, and the lower mold support platform 110 is provided above the lower mold base 130. The lower mold base 130 includes two parallel lower mold support legs, and the lower mold support platform 110 is arranged laterally between the two lower mold support legs.

[0098] An installation space is formed at the bottom of the lower mold support platform 110.

[0099] The lower mold moving module 200 is arranged in the installation space and is located at the bottom of the lower mold support platform 110, which facilitates the lower mold vision component 230 to take pictures of the marking point 910 on the light panel 900 on the lower mold support platform 110.

[0100] Includes a lower mold X-axis moving module 210; The lower mold X-axis moving module 210 and the lower mold Y-axis moving module 220 are connected together, and the lower mold vision component 230 is provided on the Y-axis moving module.

[0101] The Y-motion module can drive the lower mold vision component 230 to move in the Y direction, and the X-motion module can drive both the Y-motion module and the lower mold vision component 230 to move in the Y direction, so as to realize the positional changes of the lower mold vision component 230 in the X and Y directions, so that it can capture and calibrate the positions of multiple marker points 910 on multiple light panels 900.

[0102] In some embodiments of this application, a bidirectional transfer line 700 is also included, which is laterally arranged above the lower mold support platform 110, and includes: The conveyor frame 710 has a hollow center to create clearance space for the downward movement of the aluminum frame pickup component 363 and the lamp panel pickup carrier 340. When the aluminum frame pickup component 363 and the light panel pickup carrier 340 move down, they can pass through this clearance space to reach the position of the lower mold support platform 110.

[0103] The first transfer component 720 is disposed at one end of the conveyor frame and slidably connected to the conveyor frame 710. It can move along the conveyor frame 710 from one end of the conveyor frame 710 toward the center of the conveyor frame 710. The first drive transmission module 730 is connected to the first transfer component 720 and is used to drive the first transfer component 720 to slide. The first transfer component 720 is a lamp panel 900 transfer component, which is the first transfer plate and is slidably connected to the conveyor frame.

[0104] The first drive transmission module 730 is a linear module of motor pulley belt 3653, which can be used to drive the first transfer component 720 to move back and forth along the conveyor frame between the middle position and one end of the conveyor frame.

[0105] To prevent the lamp panel 900 placed on the first transfer component 720 from falling off, a positioning structure for positioning the lamp panel 900 is provided on the first transfer component 720. Multiple lamp panel placement positions 120 are formed on the first transfer component 720. Retractable positioning cylinders are provided between adjacent lamp panel placement positions 120 and at the outer edge of the lamp panel placement positions 120. The top of the positioning cylinder is connected to a positioning pin, which can be extended to position the lamp panel 900.

[0106] The second transfer component 740 is disposed at the other end of the conveyor frame 710, slidably connected to the conveyor frame 710, and movable along the conveyor frame 710 from one end of the conveyor frame 710 toward the center position of the conveyor frame 710. The second drive transmission module 750 is connected to the second transfer component 740 and is used to drive the second transfer component 740 to slide.

[0107] The second transfer component 740 is a second transfer plate, which is used to transfer the aluminum frame 800. It can also be moved from the other end of the conveyor frame 710 to the middle position of the conveyor frame 710 under the drive of the second drive transmission module 750, and move back and forth between the two positions to realize the transfer of the aluminum frame 800 and the lamp panel 900.

[0108] The upper mold module 300 is located above the middle position of the conveyor frame, and the lower module support platform is located below it.

[0109] The second drive transmission module 750 can also be a linear module with a motor pulley belt 3653, or other linear module structures, which will not be elaborated here.

[0110] To achieve the positioning of the aluminum frame 800 placed on the second transfer component 740, multiple clamping and positioning cylinders are installed on the second transfer component 740 during installation to clamp and position the aluminum frame 800.

[0111] The bidirectional conveyor line can be used to transport the lamp panel 900 and the aluminum frame 800 separately to the middle position of the conveyor frame 710, and can move back and forth multiple times to achieve the effect of back-and-forth handling of the lamp panel 900 and the aluminum frame 800.

[0112] The present invention also proposes a visual positioning adjustment method based on the upper and lower mold visual positioning adjustment device described in the above embodiments, for obtaining the position of the light board 900 and adjusting the position of the light board 900, including the following steps: The upper mold vision component 310 on the upper mold module 300 takes a picture to obtain the position of the two markers 810 on the aluminum frame 800 in the machine coordinate system and transmits it to the controller. The controller establishes the product coordinate system inside the controller through the two markers 810. Specifically, the entire device has a machine coordinate system, and the position of the upper mold vision component 310 in the machine coordinate system has been calibrated.

[0113] The position of the upper mold vision component 310 in the machine coordinate system is known.

[0114] It can take pictures of the marking pieces 810 on the aluminum frame 800. The upper mold vision component 310 is equipped with two parts, which take pictures of the two collinear marking pieces 810 on the aluminum frame 800 respectively. By taking pictures of the marking pieces 810, the position of the two marking pieces 810 in the machine coordinate system is automatically obtained.

[0115] After obtaining the positions of the two markers 810 in the machine coordinate system, the controller obtains the positions of the two markers 810 and suggests a product coordinate system.

[0116] Specifically, the Y-axis is formed by connecting the two markers 810, and the X-axis is formed by drawing a straight line perpendicular to the Y-axis through one of the markers 810. The product coordinate system is established by the X-axis and the Y-axis.

[0117] The controller controls the lower mold moving module 200 to move the lower mold vision component 230 to move to the marking points 910 of multiple light panels 900 to take pictures of the marking points 910. After taking pictures, the lower mold vision component 230 directly transmits the position of the marked point 910 in the machine reference coordinate system to the controller. In some embodiments of this application, four light panels 900 are provided, and the four light panels 900 need to be spliced ​​together to form a whole light panel 900.

[0118] The lamp panel 900 includes a first side that is parallel to the X-axis, and the first side has two lamps. And a second side is set perpendicular to the X-axis, and there are two of the second side.

[0119] Each light panel 900 is equipped with two marker points 910, which are located near the two first side edges.

[0120] Since the lower mold vision component 230 is located in the machine coordinate system, it is moved by the lower mold moving module 200. During the movement driven by the lower mold moving module 200, its position in the machine coordinate system is known. After taking a picture, the position of the marker point 910 in the machine coordinate system can be obtained accordingly.

[0121] In some embodiments of this application, the lower mold vision component 230 is a lower mold vision camera, which has the function of obtaining its coordinate position directly through the photographing marker point 910. This is an existing technology and will not be described in detail here.

[0122] The lower mold vision component 230 transmits the coordinate position of the marker point 910 to the controller.

[0123] The controller can calculate and analyze the actual position of the marker point 910 in the product coordinate system based on the position of the marker point 910 in the machine reference coordinate system and the position of the marker point 910 in the product coordinate system. The actual coordinate position of the marker point 910 in the product coordinate system includes the X value and the Y value of the marker point 910.

[0124] The dimensional deviation is calculated based on the actual coordinate position of the marker 910 and the reference coordinate position pre-existing in the controller.

[0125] In specific settings, each light panel 900 is provided with at least 2 marker points 910. For ease of description, this embodiment uses 2 marker points 910 as an example. The 2 marker points 910 are connected to form a marker line.

[0126] During detection, priorities are set in the controller, with the priority of angle deflection judgment being higher than that of position offset.

[0127] After the lower mold vision component 230 detects the coordinates of two marker points 910, it transmits the information to the controller. The controller determines whether the light panel 900 is deflected based on the angle between the marker line formed by connecting the coordinates of the two marker points 910 and the Y-axis.

[0128] If the marking line and the Y-axis are within the preset angle range, it means that the light panel has not deflected by 90 degrees.

[0129] If the angle between the two is not within the preset angle range, it means that the light panel is deflected by 90 degrees.

[0130] The angle value that the lamp panel 900 needs to be adjusted is obtained based on the detected included angle and the upper or lower limit angle value of the preset angle range. The control rotation module 330 drives the lamp panel 900 to rotate for adjustment.

[0131] If the included angle is less than the lower limit of the preset angle range, the lamp panel 900 is controlled to rotate away from the Y-axis; otherwise, the lamp panel 900 is controlled to rotate closer to the Y-axis.

[0132] After determining the deflection angle of the lamp panel 900, it is then determined whether the lamp panel 900 has shifted in the X or Y direction.

[0133] For ease of description, in this embodiment, the actual X value of the marker point 910 is called the actual X value, the X value pre-stored in the controller is called the reference X value, the actual Y value is called the actual Y value, and the Y value pre-stored in the controller is called the reference Y value.

[0134] The difference between the actual X value and the reference X value of the two marker points 910 was detected to be within the first preset deviation range; If the difference between the actual Y value and the reference Y value of the two marker points 910 is not within the second preset deviation range, it means that the lamp panel 900 has shifted in the Y direction.

[0135] At this point, it is necessary to control the three-way movement module 320 to drive the lamp board picking component 350 to adsorb the lamp board 900 and move it along the Y-axis direction for position adjustment.

[0136] Specifically, when the difference between the actual Y value and the reference Y value of the two marker points 910 is less than the lower limit of the second preset deviation range, the lamp board 900 can be moved away from the origin of the product coordinate system along the Y axis by the lamp board picking component 350.

[0137] When the difference between the actual Y value and the reference Y value of the two marker points 910 is greater than the upper limit of the second preset deviation range, the lamp board 900 can be moved along the Y axis towards the origin of the product coordinate system by the lamp board picking component 350.

[0138] The difference between the actual X value and the reference X value of two marker points 910 was detected to be outside the first preset deviation range; If the difference between the actual Y value and the reference Y value of the two marker points 910 is within the second preset deviation range, it means that the lamp panel 900 has shifted in the X direction.

[0139] At this point, it is necessary to control the three-way movement module 320 to drive the lamp board picking component 350 to adsorb the lamp board 900 and move it along the X-axis direction for position adjustment.

[0140] Specifically, when the difference between the actual X value and the reference X value of the two marker points 910 is less than the lower limit of the first preset deviation range, the lamp board 900 can be moved away from the Y axis along the X axis by the lamp board picking component 350.

[0141] When the difference between the actual X value and the reference X value of the two marker points 910 is greater than the upper limit of the first preset deviation range, the lamp board 900 can be moved along the X axis towards the Y axis by the lamp board pickup component 350.

[0142] When the angle between the marking line and the Y-axis of the two marking points 910 is within the preset angle range, the difference between the actual X value and the reference X value of the two marking points 910 is not within the first preset deviation range; If the difference between the actual Y value and the reference Y value of the two marker points 910 is not within the second preset deviation range, it means that the lamp panel 900 has shifted in the X and Y directions.

[0143] At this point, the three-way moving module 320 can be controlled to drive the lamp board picking component 350 to adjust in one direction and then in the other direction. The adjustment method is the same as described above and will not be repeated here.

[0144] In this embodiment, when adjusting the offset, the three-way movement module 320 moves at a set interval, and after moving, it takes another picture through the lower mold vision component 230, which is then transmitted to the controller for analysis and calculation. When the rotating module 330 is adjusted, it rotates at a preset angle. After the rotation is completed, the lower mold vision component 230 takes another picture to obtain new position information and sends it to the controller. The controller then calculates and judges again to ensure the accuracy of the position adjustment of the lamp board 900.

[0145] After all the light panels 900 are adjusted to their positions, the lower mold vision component 230 moves along the lower moving module and passes through all the marker points 910 to recheck whether the actual position coordinates of the marker points 910 are qualified.

[0146] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions claimed by the present invention.

8. A visual positioning adjustment method based on the upper and lower mold visual positioning adjustment device according to any one of claims 1-7, used to obtain the position of the light board and adjust the position of the light board, wherein each light board is provided with at least 2 marker points, and multiple marker points of each light board are connected to form a marker line, characterized in that, The steps include the following: The upper mold vision component takes a picture to obtain the coordinate positions of two markers on the aluminum frame in the machine coordinate system, and transmits the position information to the controller. The controller establishes a product coordinate system based on the coordinate positions of the two markers. The product coordinate system has an X-axis and a Y-axis, and the marker line extends along the Y-axis. The controller controls the lower mold moving module to move the lower mold vision component, take pictures of the marking points on the light board to obtain the coordinate position of each marking point in the machine reference coordinate system, and the lower mold vision component transmits the coordinate position of each marking point to the controller. The controller calculates and obtains the actual coordinate position of the marker point in the product coordinate system based on the position of the marker point in the machine reference coordinate system and the coordinate position of the product coordinate system. The deflection angle of the light panel is determined by the angle between the marker line formed by connecting the actual coordinates of multiple marker points and the Y-axis. The offset value of the marker point is obtained by comparing its actual coordinate position with the reference coordinate position stored in the controller, and the adjustment module is controlled to operate based on the deflection angle and the offset value.

9. A visual positioning adjustment method based on the upper and lower mold visual positioning adjustment device of claim 8, characterized in that, Determining the deflection angle of the light panel involves the following steps: Check whether the indicator line and the Y-axis are within the preset angle range. If so, it means that the light panel has not deflected. If the angle between the two is not within the preset angle range, it means that the light panel is deflected. The angle value that the lamp panel needs to be adjusted is obtained based on the detected included angle and the upper or lower limit angle value of the preset angle range. The rotation module is then controlled to drive the lamp panel to rotate for adjustment. After determining the deflection angle of the light panel, it is then determined whether the light panel has shifted in the X or Y direction. The difference between the actual X value and the reference X value of the two identified points was detected to be within the first preset deviation range; If the difference between the actual Y value and the reference Y value of the two marker points is not within the second preset deviation range, it means that the light panel has shifted in the Y direction; The control three-way movement module drives the light panel pickup component to adsorb the light panel and move it along the Y-axis direction to adjust its position. When the difference between the actual X value and the reference X value of two identified points is not within the first preset deviation range; The difference between the actual Y value and the reference Y value of the two marker points is within the second preset deviation range, which means that the light panel has shifted in the X direction; The control three-way movement module drives the lamp board pickup component to adsorb the lamp board and move it along the X-axis direction to adjust its position.
