Description

Technical Field

[0001] This utility model relates to the field of display device manufacturing technology, and in particular to a cutting device for display panels. Background Technology

[0002] During the manufacturing process of display panels, a protective film containing metal particles needs to be applied to the panel to provide waterproofing and oxidation protection for the transistors, circuits, and other electronic components. Display panels are typically manufactured from a large glass substrate. After the electronic components are manufactured, the entire glass substrate is cut into predetermined sizes using cutting equipment to form individual display panels. (See reference...) Figure 1 As shown, an existing cutting device includes a drive assembly 1', a cutting assembly 2', and a positioning assembly 3'. The drive assembly 1' transports a display panel 4' to the cutting station. The positioning assembly 3' is positioned above the drive assembly 1' and uses an industrial camera to identify a positioning target on the display panel 4' to determine if it is in the correct cutting position. The cutting assembly 2' is positioned above the drive assembly 1' and performs the cutting operation on the display panel 4' after it has been adjusted to the correct cutting position.

[0003] The existing cutting equipment has the following shortcomings: Because the display panel 4' is covered with a protective film containing metal particles, this protective film has high strength and hardness but poor flexibility, causing the display panel 4' to warp after the film is applied. When the positioning target is located in the warped area, the positioning target cannot be aligned with the industrial camera, causing the image of the positioning target obtained by the industrial camera to be stretched or blurred, which in turn prevents the positioning component 3' from completing the positioning operation. Utility Model Content

[0004] The purpose of this invention is to provide a cutting device for display panels, which has high reliability and accurate positioning.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A cutting device for display panels is provided, comprising:

[0007] A driving component is used to carry the display panel and move the display panel to the cutting station;

[0008] An adsorption assembly is disposed at the cutting station. The adsorption assembly includes a base and an adsorption platform disposed on the top of the base. The adsorption platform is rotatably connected to the base. The adsorption platform can reciprocate relative to the base along the moving direction of the display panel. The top surface of the adsorption platform forms the reference surface of the cutting station. A plurality of adsorption holes are provided on the reference surface.

[0012] As a preferred embodiment of the cutting equipment for display panels, the base further includes a guide rod, one end of which is connected to the return plate and the other end of which passes through the limiting plate, and the spring is sleeved on the guide rod.

[0013] As a preferred embodiment of a cutting device for display panels, the base includes a plurality of rotatably arranged support wheels, which are spaced apart along the moving direction of the display panel, and the support wheels are used to support the adsorption platform.

[0019] As a preferred embodiment of the cutting equipment for display panels, it also includes a pressure bar, which is vertically and vertically mounted on the gantry frame and is used to drive the display panel against the reference surface.

[0020] The advantages of this utility model compared to the prior art are:

[0021] This invention relates to a cutting device for display panels. By adsorbing the display panel onto a reference surface, the area of ​​the display panel below the industrial camera remains horizontal and directly facing the camera. This ensures that the industrial camera can effectively identify the positioning target on the display panel, preventing image stretching or blurring of the positioning target obtained by the camera, and making positioning more reliable and accurate. Furthermore, when adjusting the position of the display panel, it is necessary to move the display panel back and forth.

[0031] The advantages and features of this invention, as well as methods of implementing them, will become apparent from the following detailed description of the embodiments in conjunction with the accompanying drawings. However, this invention is not limited to the embodiments disclosed below, but can be implemented in various different forms. These embodiments are provided merely to complete the disclosure of this invention and to enable those skilled in the art to fully understand its scope, which is defined only by the scope of the claims. The same reference numerals denote the same constituent elements throughout the specification.

[0032] The present invention will now be described in detail with reference to the accompanying drawings.

[0033] like Figures 2 to 4As shown, a cutting device for display panels (hereinafter referred to as the cutting device) is provided for cutting display panels 7 to divide a whole display panel 7 into individual display panels 7. The cutting device includes a driving component 1, an adsorption component 6, a positioning component 3, and a cutting component 2. The driving component 1 carries the display panel 7 and moves it to the cutting station. The cutting component 2 is disposed at the cutting station and is used to cut the display panel 7. The adsorption component 6 is used to adsorb the display panel 7 and is disposed at the cutting station. The adsorption component 6 includes a base 63 and an adsorption platform 61. The adsorption platform 61 is disposed on top of the base 63 and is rotatably connected to the base 63, allowing the adsorption platform 61 to move relative to the base 63. The adsorption platform 61 can reciprocate on the base 63 along the moving direction of the display panel 7. That is, the adsorption platform 61 can move forward and backward along the moving direction of the display panel 7. The top surface of the adsorption platform 61 forms a reference surface 610 for the cutting station, which matches the preset position of the display panel 7 when it is cut. The reference surface 610 has several adsorption holes 611, which use vacuum adsorption to adsorb the display panel 7, ensuring it rests flat against the reference surface 610. A positioning component 3 is used to position the display panel 7. This component includes an industrial camera 31, positioned above the reference surface 610, which identifies a positioning target on the display panel 7. In this embodiment, the positioning target is a crosshair target.

[0034] Understandably, when the industrial camera 31 identifies the positioning target, the positioning target must be directly facing the industrial camera 31. The industrial camera 31 obtains the position of the display panel 7 by identifying the positioning target, and adjusts the position of the display panel 7 through the drive component 1 to move the display panel 7 to the preset position during cutting. By setting the adsorption component 6 at the cutting station, the adsorption platform 61 in the adsorption component 6 can reciprocate forward and backward relative to the base 63. When positioning the display panel 7, by adsorbing the display panel 7 onto the reference surface 610, the area of ​​the display panel 7 below the industrial camera 31 is kept horizontal and directly facing the industrial camera 31, thereby ensuring that the industrial camera 31 can effectively identify the positioning target on the display panel 7 and avoiding stretching or blurring of the image of the positioning target obtained by the industrial camera 31. Furthermore, when adjusting the position of the display panel 7, it is necessary to move the display panel 7 back and forth. By rolling the adsorption platform 61 to the base 63, the adsorption platform 61 can move synchronously with the display panel 7, so as to avoid the display panel 7 having difficulty moving under the adsorption of the adsorption platform 61, and thus make the display panel 7 move smoothly when adjusting its position.

[0035] Specifically, refer to Figure 2 and Figure 3 As shown, there are two drive components 1, which are arranged at intervals along the moving direction of the display panel 7 (X direction in the figure). The adsorption component 6 is located between the two drive components 1. The position of the adsorption component 6 corresponds to the cutting station. The drive component 1 located upstream of the adsorption component 6 is used to move the display panel 7 to the cutting station, and the drive component 1 located downstream of the adsorption component 6 is used to move the cut display panel 7 to the subsequent station.

[0036] The drive assembly 1 includes a conveyor belt 11, drive wheels 12, drive shafts 13, and a first transmission chain 14. Multiple conveyor belts 11 are arranged at intervals along a first direction (Y direction in the diagram), perpendicular to the movement direction of the display panel 7. The conveyor belts 11 are horizontally positioned so that the display panel 7 can be placed horizontally on them. By using multiple conveyor belts 11, the overall width of the display panel 7 can be accommodated. In practical applications, the number and spacing of the conveyor belts 11 can be flexibly selected according to the width of the display panel 7. Drive wheels 12 are respectively provided at both ends of the conveyor belts 11, and the conveyor belts 11 are wound around the drive wheels 12, which drive the conveyor belts 11 to rotate. Two drive shafts 13 are arranged at intervals along the movement direction of the display panel 7, located at opposite ends of the conveyor belts 11. All drive wheels 12 located at the same end of the conveyor belts 11 are mounted on their corresponding drive shafts 13. This means that multiple drive wheels 12 can be driven to rotate synchronously by a single drive shaft 13, which simplifies the overall structure of the cutting equipment. A first transmission chain 14 is connected to both drive shafts 13, and a power source consisting of a motor and a gearbox is also connected to the first transmission chain 14. The first transmission chain 14 drives the two drive shafts 13 to rotate, which in turn drives the conveyor belt 11 to rotate. In this embodiment, the first transmission chain 14 and the conveyor belt 11, among other transmission components, are all existing technologies, and their specific structures and working principles will not be described in detail here.

[0037] The cutting equipment also includes a frame 4 and a gantry 5. The frame 4 provides support and installation space for the entire cutting equipment and is a steel frame structure composed of several profiles. The gantry 5 is mounted on the frame 4 and spans across the cutting station. Both the cutting assembly 2 and the positioning assembly 3 are mounted on the gantry 5. The cutting assembly 2 includes a first drive component 21, a cutter head 22, a base 23, and a second transmission chain 24. The base 23 is slidably mounted on the gantry 5 and can slide along the length direction of the gantry 5 (Y direction in the diagram). The second transmission chain 24 is mounted on the gantry 5 and is connected to a power source consisting of a motor and a gearbox, driving the base 23 to move on the gantry 5. The first drive component 21 is an existing telescopic drive device such as a cylinder, hydraulic cylinder, or linear motor. The first drive component 21 is mounted on the base 23, and the cutter head 22 is mounted on the output end of the first drive component 21. The first drive component 21 is used to drive the cutter head 22 to move up and down. During the cutting operation, the first drive component 21 drives the cutter head 22 to descend and contact the display panel 7. Then, the second transmission chain 24 drives the base 23 to move, causing the cutter head 22 to move across the surface of the display panel 7 to cut it. The positioning component 3 is prior art, comprising an industrial camera 31 and a host computer. The industrial camera 31 is electrically connected to the host computer, and the image data acquired by the industrial camera 31 is transmitted to the host computer. The drive component 1 is electrically connected to the host computer, and the host computer controls the movement of the drive component 1 in real time based on the detection data to adjust the position of the display panel 7.

[0038] The cutting equipment also includes a pressure rod 8 and a second drive component 9. The second drive component 9 is an existing telescopic drive device such as a cylinder, hydraulic cylinder, or linear motor. The second drive component 9 is mounted on the gantry frame 5, and the pressure rod 8 is mounted on the output end of the second drive component 9. The second drive component 9 is used to drive the pressure rod 8 to rise and fall, that is, to enable the pressure rod 8 to be raised and lowered on the gantry frame 5. The pressure rod 8 has a round rod structure, and its length extends along the Y direction shown in the figure. Through the rising and falling movement of the pressure rod 8, the display panel 7 is driven to abut against the reference surface 610. When the warpage of the display panel 7 is large and the adsorption component 6 cannot adsorb the display panel 7, the pressure rod 8 can be used to press down on the display panel 7 so that the display panel 7 abuts against the adsorption component 6.

[0039] Specifically, there are multiple adsorption components 6, which are arranged sequentially along a first direction perpendicular to the moving direction of the display panel 7. By setting multiple adsorption components 6, each adsorption component 6 independently adsorbs the display panel 7. When different areas of the display panel 7 have different warpages, some adsorption components 6 can first adsorb the areas of the display panel 7 that are closer to the adsorption platform 61, and then use the adsorbed areas to pull the unadsorbed areas closer, thereby promoting the adsorption effect of the adsorption components 6 on the display panel 7.

[0040] Specifically, refer to Figure 4 As shown, the adsorption assembly 6 includes an adsorption platform 61, support wheels 62, a base 63, a return plate 64, and an air pump. The adsorption platform 61 is positioned on top of the base 63, and its top surface forms a reference surface 610. An air chamber 612 is formed within the adsorption platform 61, and all adsorption holes 611 communicate with the air chamber 612. The air chamber 612 is connected to the air pump via an air pipe 613, which evacuates air from the air chamber 612 to achieve the adsorption function. The base 63 includes a limiting plate 631, a guide rod 632, a spring 633, and a support frame 634. The support frame 634 provides overall support. Two limiting plates 631 are spaced apart on the support frame 634 along the moving direction of the display panel 7. Multiple support wheels 62 are rotatably mounted on the support frame 634 and are spaced apart along the moving direction of the display panel 7. Support wheels 62 support the adsorption platform 61, ensuring a rolling connection between the adsorption platform 61 and the base 63. A return plate 64 is located at the bottom of the adsorption platform 61, extending from one end away from the adsorption platform 61 to between two limiting plates 631. Two guide rods 632 are provided, one on each of the two limiting plates 631. One end of each guide rod 632 is connected to the return plate 64, and the other end passes through the corresponding limiting plate 631, allowing the guide rod 632 to slide on the limiting plate 631. A spring 633 is sleeved on the guide rod 632, with one end connected to the return plate 64 and the other end connected to the limiting plate 631, enabling an elastic connection between the return plate 64 and the limiting plate 631 via the spring 633. In this embodiment, the return plate 64 is located in the middle between the two limiting plates 631, corresponding to the initial position of the adsorption platform 61. During the positioning process, a portion of the display panel 7 is adsorbed onto the adsorption platform 61, while the remaining area rests on the drive assembly 1. When the position of the display panel 7 needs adjustment, the drive assembly 1 drives the display panel 7 forward or backward, causing the adsorption platform 61 to move forward or backward synchronously with the display panel 7. After cutting is completed, the return plate 64 returns to the middle position between the two limiting plates 631 under the rebound action of the spring 633, thus returning the adsorption platform 61 to its initial position. Of course, in some embodiments, if the spring 633 can meet the installation requirements and elastic movement, the guide rod 632 can be omitted, and the two ends of the spring 633 can be directly connected to the limiting plate 631 and the return plate 64 respectively.

[0041] Specifically, to improve the stability of the adsorption platform 61 when it returns to its original position, two springs 633 are provided between the same side of the return plate 64 and the corresponding limiting plate 631. The two springs 633 are arranged along the first direction to prevent the adsorption platform 61 from getting stuck when it returns to its original position.

[0042] The beneficial effects of this embodiment are as follows: By adsorbing the display panel 7 onto the reference surface 610, the area of ​​the display panel 7 below the industrial camera 31 is kept horizontal and directly facing the industrial camera 31. This ensures that the industrial camera 31 can effectively identify the positioning target on the display panel 7, avoiding stretching or blurring of the image of the positioning target obtained by the industrial camera 31, and making the positioning more reliable and accurate. Furthermore, when adjusting the position of the display panel 7, it is necessary to move the display panel 7 back and forth. By rolling the adsorption platform 61 to the base 63, the adsorption platform 61 can move synchronously with the display panel 7, avoiding difficulty in moving the display panel 7 under the adsorption of the adsorption platform 61, thus enabling smooth movement of the display panel 7 during position adjustment.

[0043] Although embodiments of the present invention have been described above with reference to the accompanying drawings, the present invention is not limited to the above embodiments, but can be made in various forms, and those skilled in the art will understand that the present invention can be implemented in other specific forms without changing the technical spirit or essential characteristics of the present invention. Therefore, it should be understood that the above embodiments are exemplary in all respects and not restrictive.
