Description

Technical Field

[0001] The invention relates to television assembly equipment, in particular to an adaptive panel flattening machine. Background Art

[0002] The TV screen needs to be installed inside the TV case. Previously, the LCD screen was sucked up by a robot and then placed in the TV case. The edge of the screen was pressed against the circular step inside the TV case by a roller and evenly glued with glue.

[0003] However, because the robot's grasping accuracy is not very high, and the gap between the LCD screen and the shell around the annular step is very small, when the robot places the LCD screen on the step surface inside the TV shell, the corners of the LCD screen are easily placed on the shell around the annular step to form a warp. If the position of the LCD screen is not corrected at this time, it is easy to cause damage to the corners of the LCD screen or damage to the roller when it is subsequently pressed by the roller (the roller is made of silicone, and the corners are easy to poke the roller when they are warped unevenly).

[0004] Therefore, workers will be arranged to perform pre-pressing (to correct the position of the LCD screen) before the roller is pressed, and manually press the corners of the LCD screen into the TV housing to ensure smooth subsequent roller pressing. However, manual operation is inefficient and results in high production costs. If an ordinary cylinder is used to drive a pressing plate to punch the corners of the LCD screen, the pressing plate cannot fit the screen, resulting in excessive local pressure and easy damage to the screen. Therefore, the applicant has designed an adaptive panel flattening machine for the above installation link to solve the above problem. Summary of the invention

[0030] Reference Figures 1 to 4The present invention discloses an adaptive panel flattening machine, comprising a machine platform 1, on which a bracket 2 for supporting a TV housing, a fine-tuning plate 3 for pushing a screen, and a pressing frame 4 are arranged. The pressing frame 4 is arranged on the machine platform 1 through a pushing driving unit 5 so as to realize the lifting and pressing down of the pressing frame 4. The fine-tuning plate 3 is connected to the pressing frame 4 through an elastic adjustment structure so as to realize swinging and fully fit with the screen, and the screen is fully pushed into the TV housing through the pushing of the pushing driving unit 5. The screen of the present application is a liquid crystal screen, which is a fragile item, and therefore it is not It can be directly stamped using an ordinary stamping structure, and is located above the corner of the screen. It can swing through an elastic adjustment structure, so that it can fully fit with the screen when the corner of the screen is warped. The purpose of the fitting is not only to disperse the pressure applied to the screen, but also to increase the friction between the fine-tuning plate 3 and the screen. Therefore, under the push of the pushing drive unit 5, the screen not only bears pressure but also is affected by the friction with the fine-tuning plate 3, so that it can move under the action of friction, and thus be stuck in the TV casing, avoiding damage due to direct pressure. When pushing a corner, the fine-tuning plates 3 of the present application are configured in pairs, and the two fine-tuning plates 3 are arranged vertically, so that the screen can be effectively acted in both the horizontal and vertical directions and finally corrected to the correct position. The screen of the present application requires two pairs of fine-tuning plates 3, a pressure frame 4 and an elastic adjustment structure to pre-press two adjacent right-angle corners of the screen, thereby realizing the position correction of the screen. As a preferred structure, an elastic plate 6 is provided on the fine-tuning plate 3. The elastic plate 6 is made of rubber, which not only has a large friction with the screen, but also has a certain buffering effect and is not easy to damage the screen. The pushing drive unit 5 is preferably a cylinder, and the elastic plate 6 also has a positioning edge.

[0031] As a specific preference, the elastic adjustment structure includes a plurality of elastic members 7 disposed between the fine-tuning plate 3 and the pressure frame 4, and the elastic members 7 are preferably springs, and the fine-tuning plate 3 can be fitted with the screen through the deformation of the elastic members 7. As a further structure, the elastic adjustment structure of the present application also includes relatively disposed elastic members 7, a pin 8, an axial hole 1 disposed on the fine-tuning plate 3, and an axial hole 2 disposed on the pressure frame 4, and the pin 8 penetrates into the axial hole 1 and the axial hole 2. Because if there are springs between the fine-tuning plate 3 and the pressure frame 4, the pressure of the fine-tuning plate 3 is difficult to control and monitor, and therefore the fine-tuning plate 3 of the present application is directly hinged to the pressure frame 4, forming a direct pressure application point at the hinge point, and the combination with the elastic member 7 can ensure that the fine-tuning plate 3 can swing and fit tightly with the screen and apply a certain pressure. As a further structure, a pulling pressure sensor 9 is provided between the pressing frame 4 and the pushing drive unit 5, so that we can monitor the thrust applied to the fine-tuning plate 3 through the pulling pressure sensor 9, and control the pressure entering the cylinder by controlling the proportional valve, thereby controlling the thrust of the cylinder, thereby adjusting the thrust applied to the fine-tuning plate 3. The proportional valve is an existing component and will not be described in detail.

[0032] The elastic member 7 is a spring, the fine-tuning plate 3 is provided with a mounting hole 1, the pressure frame 4 is provided with a mounting hole 2, one end of the spring is located in the corresponding mounting hole 1 and the other end of the spring is located in the corresponding mounting hole 2.

[0033] As shown in the figure, a connecting block 10 is provided on the pressing frame 4, and a supporting plate 11 is provided on the fine-tuning plate 3. The connecting block 10 is located between the supporting plates 11, the second axial hole is located on the connecting block 10, and the first axial hole is arranged on the supporting plate 11. The above structure is convenient for manufacturing and assembly.

[0034] As shown in the figure, the machine 1 is provided with a micro-motion platform 12 and a driving motor 13, and a micro-motion plate 14 connected to the micro-motion platform 12. The pushing driving unit 5 and the pressure frame 4 are arranged on the micro-motion plate 14. The micro-motion platform 12 is an externally purchased part, which can accurately adjust the linear position of the pushing driving unit 5 and the pressure frame 4 in a small range, thereby adjusting the linear position of the fine-tuning plate 3.

[0035] As shown in the figure, the machine 1 is provided with a lifting mechanism and a lifting frame 15 driven by the lifting mechanism, the bracket 2 is arranged on the lifting frame 15, the lifting mechanism includes a lifting motor 16, a lifting guide rail assembly 17 and a lifting screw assembly 18, the lifting motor 16 is connected to the lifting screw assembly 18, and the lifting frame 15 is connected to the lifting guide rail assembly 17 and the lifting screw assembly 18. When the screen moves to the pre-pressing position, the lifting mechanism drives the lifting frame 15 to rise, so that the bracket 2 supports the TV housing, which is convenient for subsequent stamping.

[0036] As shown in the figure, the machine 1 is provided with a translation mechanism and a translation frame 19 driven by the translation mechanism. The micro-motion plate 14, the micro-motion platform 12 and the driving motor 13, the lifting mechanism and the lifting frame 15 are all arranged on the translation frame 19. The translation mechanism can realize a large range of rapid movement of the pushing drive unit 5, the pressure frame 4 and the fine-tuning plate 3, thereby improving work efficiency. The translation mechanism adopts two vertically arranged linear motors 20, which can drive the translation frame 19 to realize movement in the plane. The above is a conventional technology, so the specific structure is not described in detail, and then cooperates with the micro-motion platform 12 to realize precise position adjustment, which is not only efficient but also cost-saving.
