Abstract
Description
Technical Field
[0001] This utility model relates to the field of material clamping technology, and in particular to a clamping mechanism for a backlight assembly machine. Background Technology
[0002] The backlight is the light source behind an LCD display, responsible for providing uniform light so that the LCD panel can display images. A backlight assembly machine is an automated production line designed specifically for small backlight modules. Its core function is to automate the entire process of backlight module frame feeding, cleaning and dust removal, precise attachment of multi-layer optical films, and final pressing into finished products through a precision mechanical structure and vision positioning system.
[0003] As an important component of backlight assembly machines, the clamping mechanism enables the clamping and transfer of materials. A typical clamping mechanism in an existing backlight assembly machine includes a substrate, a first moving component slidably mounted on the substrate, and a clamping component. In use, the first moving component drives the clamping component to perform linear displacement. This driving method has several drawbacks: 1. Limited freedom of motion; the clamping component can only achieve planar displacement along a single axis, failing to meet the operational requirements of complex assembly paths in three-dimensional space; 2. Lack of a buffering mechanism at the clamping end, which can easily lead to scratches, deformation, and other quality problems on the material surface during gripping. Utility Model Content
[0004] Therefore, it is necessary to provide a clamping mechanism for a backlight assembly machine.
[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A clamping mechanism for a backlight assembly machine includes a substrate, a first moving component slidably disposed on the substrate, and a clamping component. The mechanism further includes a second moving component slidably disposed on the first moving component, a third moving component slidably disposed on the second moving component, and a rotary driver fixedly assembled on the third moving component. The clamping component is fixedly disposed on the driving end of the rotary driver. The clamping component is a finger cylinder with two rows of openable or closeable gripper fingers. The gripper fingers are made of flexible material, and deformation grooves are formed inside the gripper fingers.
[0006] Furthermore, the cross-section of the deformation groove is rectangular.
[0007] Furthermore, the first moving component includes a guide rail fixed to the substrate, a slider slidably assembled on the guide rail, and a first cylinder fixed to the substrate. The push rod of the first cylinder is fixed relative to the slider, and the second moving component is assembled on the slider.
[0008] Furthermore, the substrate is also fixed with limiting plates at opposite ends of the guide rail for limiting the stroke of the slider, and the first cylinder is respectively assembled on one of the limiting plates.
[0009] Furthermore, the second moving component is a second cylinder assembled on the slider, and the push rod on the second cylinder is also fixedly connected to a mounting plate on which the second moving component is assembled, and the direction of movement of the push rod on the second cylinder is perpendicular to the sliding direction of the slider.
[0010] Furthermore, the push rod on the second cylinder is also fixedly connected to a stop block, and the end face of the mounting plate opposite to the stop block is recessed to form a mounting groove, and the stop block is embedded and fixed in the mounting groove on the mounting plate.
[0011] Furthermore, the third moving component includes two guide rods fixed to the mounting plate and a cylinder body that slides on the two guide rails. A curved plate for a rotary driver to be assembled on is fixedly connected to the cylinder body. The sliding direction of the cylinder body and the slider is perpendicular to the movement direction of the push rod on the second cylinder.
[0012] Furthermore, mounting blocks are provided on opposite sides of the mounting plate, and the two ends of the double guide rod are respectively fixed to the mounting blocks on both sides.
[0013] Furthermore, the rotary actuator is a rotary cylinder, and a flange is also assembled and fixed at the drive end of the rotary cylinder. A rotating seat with one end for the clamping assembly to be assembled on is also assembled and fixed on the flange.
[0014] Furthermore, the substrate is also provided with a mounting side plate for fixing on a backlight assembly machine, and a support plate is connected between the mounting side plate and the substrate.
[0015] By adopting the above technical solution, the present utility model embodiment has at least the following beneficial effects: Based on the substrate carrying the first moving component and the clamping component, the present utility model embodiment further adds a second moving component, a third moving component, and a rotary driver. The second moving component is slidably disposed on the first moving component, and the third moving component is slidably disposed on the second moving component. The third moving component, in conjunction with the rotary driver integrated at its end, enables the clamping component to have multi-directional spatial displacement and rotation capabilities, allowing it to execute complex trajectories and meet the assembly requirements for multi-angle material gripping. Furthermore, the clamping component uses a finger cylinder with double-row flexible gripper fingers. The gripper fingers, through internal deformation grooves, can elastically deform upon contact with materials, better adapting to materials of different shapes and sizes, while also protecting the materials from damage.

[0023] likeFigures 1-3 As shown, an optional embodiment of this utility model provides a clamping mechanism for a backlight assembly machine, including a substrate 1, a first moving component 2 slidably disposed on the substrate 1, and a clamping component 3. The mechanism further includes a second moving component 4 slidably disposed on the first moving component 2, a third moving component 5 slidably disposed on the second moving component 4, and a rotary driver 6 fixedly assembled on the third moving component 5. The clamping component 3 is fixedly disposed on the driving end of the rotary driver 6. The clamping component 3 is a finger cylinder 30 with two rows of openable or closeable gripper fingers 31. The gripper fingers 31 are made of flexible material, and deformation grooves 310 are formed inside the gripper fingers 31.
[0024] In this embodiment of the invention, based on the substrate 1 supporting the first moving component 2 and the clamping component 3, a second moving component 4, a third moving component 5, and a rotary driver 6 are added. The second moving component 4 is slidably disposed on the first moving component 2, and the third moving component 5 is slidably disposed on the second moving component 4. The third moving component 5, in conjunction with the rotary driver 6 integrated at its end, enables the clamping component 3 to have multi-directional spatial displacement and rotation capabilities, allowing it to execute complex trajectories and meet the assembly requirements for gripping materials from multiple angles. In addition, the clamping component 3 adopts a finger cylinder 30 with double rows of flexible gripper fingers 31. The gripper fingers 31 can generate elastic deformation when in contact with materials through internal deformation grooves 310, which can better adapt to materials of different shapes and sizes, and also helps to protect the materials from damage.
[0025] In one optional embodiment of this utility model, such as Figure 1 and Figure 2 As shown, the cross-section of the deformation groove 310 is rectangular. In this embodiment, the deformation groove 310 is rectangular in shape, which is simple in structure and easy to process and form.
[0026] In one optional embodiment of this utility model, such as Figures 1-3 As shown, the first moving component 2 includes a guide rail 20 fixed to the base plate 1, a slider 21 slidably assembled on the guide rail 20, and a first cylinder 22 fixed to the base plate 1. The push rod of the first cylinder 22 is fixed relative to the slider 21, and the second moving component 4 is assembled on the slider 21. In this embodiment, the guide rail 20 and the slider 21 form a guiding mechanism. The first cylinder 22 provides power, and the push rod on the first cylinder 22 connects to the slider 21 to achieve linear motion. The second moving component 4 is assembled on the slider 21, thereby accurately driving the second moving component 4 to move as a whole with good stability.
[0027] In one optional embodiment of this utility model, such as Figures 1-3As shown, limiting plates 23 for restricting the stroke of the slider 21 are fixed on the substrate 1 at opposite ends of the guide rail 20, and the first cylinder 22 is correspondingly assembled on one of the limiting plates 23. In this embodiment, by correspondingly setting two limiting plates 23 on the substrate 1, the two limiting plates 23 can prevent the slider 21 from moving out of the guide rail 20, ensuring the safety of the movement process.
[0028] In one optional embodiment of this utility model, such as Figures 1-3 As shown, the second moving component 4 is a second cylinder 41 assembled on the slider 21. A push rod on the second cylinder 41 is also fixedly connected to a mounting plate 42 on which the second moving component 4 is assembled. The direction of movement of the push rod on the second cylinder 41 is perpendicular to the sliding direction of the slider 21. In this embodiment, the second moving component 4 uses a second cylinder 41, and the push rod of the second cylinder 41 is connected to the second moving component 4 through the mounting plate 42, thereby realizing the movement of the second moving component 4 in a direction perpendicular to the sliding direction of the slider 21.
[0029] In one optional embodiment of this utility model, such as Figures 1-3 As shown, the push rod on the second cylinder 41 is also fixedly connected to a stop block 43. A mounting groove 420 is recessed on one end face of the mounting plate 42 opposite to the stop block, and the stop block 43 is embedded and fixed within the mounting groove 420 on the mounting plate 42. In this embodiment, the second cylinder 41 and the mounting plate 42 are respectively provided with a stop block 43 and a mounting groove 420. The stop block 43 and the mounting groove 420 cooperate with each other for installation, facilitating quick assembly and disassembly between the push rod of the second cylinder 41 and the mounting plate 42, thus improving assembly efficiency.
[0030] In one optional embodiment of this utility model, such as Figures 1-3 As shown, the third moving component 5 includes double guide rods 51 fixed to the mounting plate 42 and a cylinder body 52 sliding on the double guide rails 20. A curved plate 53 for assembling the rotary actuator 6 is fixedly connected to the cylinder body 52. The sliding direction of the cylinder body 52 and the slider 21 is perpendicular to the movement direction of the push rod on the second cylinder 41. In this embodiment, the third moving component 5 uses double guide rods 51, which makes the sliding of the cylinder body 52 on the double guide rods 51 more stable, and also enhances the load-bearing capacity and service life. In addition, the use of curved plate 53 facilitates the assembly of the rotary actuator 6.
[0031] In one optional embodiment of this utility model, such as Figures 1-3As shown, mounting blocks 44 are provided on opposite sides of the mounting plate 42, and the two ends of the double guide rod 51 are respectively fixed to the mounting blocks 44 on both sides. In this embodiment, by providing corresponding mounting blocks 44 on the mounting plate 42, the double guide rod 51 can be easily assembled, effectively preventing the cylinder body 52 from shaking during the sliding process.
[0032] In one optional embodiment of this utility model, such as Figures 1-2 As shown, the rotary actuator 6 is a rotary cylinder. A flange 62 is also assembled and fixed to the drive end of the rotary cylinder. A rotating seat 63, with one end for mounting the clamping assembly 3, is also assembled and fixed to the flange 62. In this embodiment, the drive end of the rotary cylinder is connected to the rotating seat 63 via the flange 62, facilitating the transmission of power from the drive end of the rotary cylinder to the rotating seat 63 and making the connection between the rotary cylinder and the rotating seat 63 more stable and reliable.
[0033] In one optional embodiment of this utility model, such as Figures 1-3 Figures 1-3 As shown, the substrate 1 is also provided with a mounting side plate 42 for fixing to the backlight assembly machine, and a support plate 15 is connected between the mounting side plate 42 and the substrate 1. In this embodiment, the mounting side plate 42 and the support plate 15 are correspondingly provided on the substrate 1, so that the substrate 1 can be more stably installed on the backlight assembly machine. At the same time, the support plate 15 can also increase the connection strength between the substrate 1 and the mounting side plate 42, avoiding structural deformation or damage caused by excessive force, and improving the stability and reliability of the clamping mechanism.
