Description

Technical Field

[0001] The present invention relates to the field of automated production technology, and in particular to a dual-Z-axis TP screen assembly system. Background Art

[0002] The panel, a touch screen commonly used in smart devices, primarily consists of a lens (panel), TP sensor (touch sensor), FPC (flexible printed circuit board), IC (touch chip), and other auxiliary materials. The touch sensor and touch chip are typically mounted directly on the flexible printed circuit board, which is then attached to the bottom of the panel. However, during assembly, the position and orientation of the flexible printed circuit board must be calibrated before it can be attached to the bottom of the panel, otherwise the touch screen will deviate. However, the characteristics of flexible printed circuit boards dictate that they are prone to movement during transport, necessitating pre-assembly position and orientation adjustments to ensure assembly accuracy. However, currently, no existing technology allows for pre-assembly adjustments of the flexible printed circuit board. Summary of the Invention

DETAILED DESCRIPTION

[0026] In order to facilitate understanding by those skilled in the art, the present invention will be further described below with reference to the embodiments and the accompanying drawings. The contents mentioned in the embodiments are not intended to limit the present invention. The present invention will be described in detail below with reference to the accompanying drawings.

[0027] like Figures 1 to 9 As shown, the present invention provides a dual Z-axis TP screen assembly system, including a drive control device 1, an adjustment mechanism 2 for adjusting the flexible circuit board, and a picking mechanism 3 for picking up the panel and assembling the panel with the flexible circuit board. The drive device is used to drive the adjustment mechanism 2 and the picking mechanism 3 to rise and fall respectively.

[0028] During operation, the present invention is installed on an external drive, which drives the present invention to translate and realize the picking up of the panel by the picking-up mechanism 3; when assembly is required, the present invention moves to the top of the flexible circuit board, and the drive control device 1 first drives the adjustment mechanism 2 to descend, allowing the adjustment mechanism 2 to adjust the position and posture of the circuit board, so that the flexible circuit board moves to the bottom of the picking-up mechanism 3; then the flexible circuit board rises and the picking-up mechanism 3 descends, so that the panel picked up by the picking-up mechanism 3 is directly attached to the flexible circuit board, so that the flexible circuit board is attached to the panel, ensuring the assembly accuracy of the two.

[0029] In this embodiment, the drive control device 1 includes a housing 11, a controller 12, two drive mechanisms 13, and two mounting plates 4. The controller 12 and the two drive mechanisms 13 are all disposed within the housing 11. The adjustment mechanism 2 and the pickup mechanism 3 are mounted on the two mounting plates 4, respectively. The controller 12 is configured to connect power and control the operation of the two drive mechanisms 13, respectively, which are used to drive the two mounting plates 4 up and down. The controller 12 is configured to control the two drive mechanisms 13 to operate in different states, thereby achieving asynchronous lifting and lowering of the two mounting plates 4. This allows the adjustment mechanism 2 and the pickup mechanism 3, respectively mounted on the two mounting plates 4, to be raised and lowered asynchronously, achieving the effect of non-interference in their operation. Furthermore, the present invention integrates both the controller 12 and the drive mechanisms 13 within the housing 11, resulting in a compact structure that effectively reduces space requirements. Specifically, a guide assembly 16 may be provided on one side of the housing 11, allowing the mounting plates 4 to slide and rise along the guide assembly 16, ensuring that they do not deviate during lifting.

[0030] Specifically, the adjustment mechanism 2 and the pick-up mechanism 3 are respectively connected to a mounting base 5, a movable member 41 is movably provided on the mounting plate 4, and a movable groove 51 for assembling the movable member 41 is provided on the top of the mounting base 5; a supporting member 42 is provided on one side of the mounting plate 4, and the mounting base 5 is provided with a supporting hole 52, and the supporting member 42 is used to be inserted into the supporting hole 52 and support the mounting base 5. Through the cooperation between the mounting plate 4 and the mounting base 5, the adjustment mechanism 2 and the pick-up mechanism 3 can be quickly assembled and disassembled. Taking the assembly as an example, specifically: when assembly is required, the movable member 41 is first controlled to move out of position, and then the mounting base 5 is assembled on the supporting member 42, that is, the supporting member 42 is passed through the supporting hole 52 and the mounting base 5 is released so that the supporting member can be supported by the supporting member 42; then the movable member 41 is reset so that the movable member 41 is inserted into the movable groove 51 for positioning, thereby achieving quick assembly of the mounting base 5, that is, achieving quick assembly of the adjustment mechanism 2 / pick-up mechanism 3.

[0031] Preferably, the movable part 41 includes a movable hook 411 and an elastic part 412, a mounting groove 43 is provided on the top of the mounting plate 4, the movable hook 411 is rotatably set in the movable groove 51, the mounting groove 43 is provided with a positioning inclined surface 53, and the elastic part 412 is used to force the movable hook 411 to hook the positioning inclined surface 53; a limiting block 421 is provided at one end of the supporting part 42 away from the mounting plate 4, and the limiting block 421 is used to interfere with the mounting seat 5 to prevent the supporting part 42 from withdrawing from the supporting hole 52.

[0032] The elastic member 412 is preferably a spring, that is, when the movable hook 411 flips backward to make way, the spring is forced to deform. After the mounting seat 5 is installed, the movable hook 411 is released, and the movable hook 411 is reset under the effect of the spring restoring the deformation and remains hooked in the movable groove 51, thereby achieving automatic reset and ensuring the positioning effect.

[0033] Preferably, the mounting plate 4 is provided with an electrical connection component 44, and the mounting seat 5 is provided with an electrical connection port 55. When the mounting seat 5 is installed on the mounting plate 4, the electrical connection port 55 is connected to the electrical connection component 44, and the controller 12 supplies power to the adjustment mechanism 2 or the picking mechanism 3 through the electrical connection component 44. More preferably, the mounting plate 4 is provided with an air connection component 45, and the mounting seat 5 is provided with an air connection port 56. When the mounting seat 5 is installed on the mounting plate 4, the air connection port 56 is connected to the air connection component 45. The drive control device 1 also includes an air supply mechanism 14, which is used to connect to an external air source and control the connection and disconnection between the external air source and the air connection mechanism. That is, the present invention uses the controller 12 node and simultaneously supplies power and controls the adjustment mechanism 2, the picking mechanism 3 and the two drive mechanisms 13. It has a compact structure and provides power to the corresponding pneumatic structure through the air connection mechanism, so that the adjustment mechanism 2 and the picking mechanism 3 can be directly connected to electricity and air through the mounting seat 5 and the mounting plate 4, simplifying the circuit and air path, thereby improving stability. In actual use, a corresponding clearance groove 15 can be provided on the side of the shell 11 where the guide component 16 is provided, which is used to make way for the air receiving component 45, so that the air receiving component 45 can enter the shell 11 through the clearance groove 15 and connect with the air receiving mechanism in the shell 11, avoiding being exposed to the outside and increasing the probability of failure; the air receiving mechanism can adopt an electromagnetic valve or other conventional structures, which will not be repeated here.

[0034] In this embodiment, the adjustment mechanism 2 includes a control component 21, a moving component 22, a limiting member 23, a pushing member 24 and a rotating member 25. The moving component 22 is used to drive the rotating member 25 to move in translation, and the rotating member 25 is used to drive the pushing member 24 to rotate horizontally. The limiting member 23 is fixed to the rotating member 25, and the pushing member 24 is used to push the flexible circuit board to move in translation and rotate. The moving component 22 and the rotating member 25 are both electrically connected to the power connection component 44. The limiting member 23 is provided with a limiting groove 231 whose shape is adapted to the shape of the flexible circuit board. The control component 21 is used to control the movement of the moving component 22 and the rotating member 25.

[0035] The present invention is used to adjust the position and posture of the flexible circuit board through the adjustment component 26, so that the flexible circuit board can be accurately assembled to the bottom of the panel. Specifically: during operation, the driving mechanism 13 controls the adjustment mechanism 2 to descend to a height suitable for the flexible circuit board, so that the limit member 23 is located on one side of the flexible circuit board, and then the rotating member 25 drives the pushing member 24 to rotate. During the rotation process, the pushing member 24 contacts the flexible circuit board and drives it to rotate until one side of the flexible circuit board contacts the inner wall of the limit groove 231, thereby completing the position and posture correction of the flexible circuit board. The moving component 22 then drives the flexible circuit board to move so that the flexible circuit board moves to the bottom of the picking-up mechanism 3, so that the picking-up mechanism 3 can be directly lowered to allow the flexible circuit board to be attached to the bottom of the panel.

[0036] Specifically, the rotating member 25 includes a rotary cylinder, the pushing member 24 is provided on the piston rod of the rotary cylinder, and the limiting member 23 is provided on the cylinder body of the rotary cylinder, and the limiting member 23 is located on one side of the pushing member 24. The moving assembly 22 includes a translation cylinder 221 and a translation seat 222. The translation cylinder 221 is provided on the mounting base 5 and is used to drive the translation seat 222 to move back and forth. The rotating member 25 is provided on the translation seat 222. The control of the pushing member 24 by the rotary cylinder simplifies the structure and helps reduce the number of maintenance.

[0037] Specifically, an adjustment assembly 26 is provided between the movable assembly 22 and the rotating member 25. The adjustment assembly 26 includes a guide rail 261, a slider 262, and a locking member 263. The guide rail 261 is mounted on the movable assembly 22, with the length of the guide rail 261 being arranged to intersect the moving direction of the movable assembly 22. The slider 262 is slidably provided on the guide rail 261. The locking member 263 and the rotating member 25 are both provided on the slider 262. The side of the guide rail 261 is provided with a plurality of locking holes 264 arranged side by side. The locking member 263 is used to cooperate with one of the locking holes 264 to achieve a fixed lock of the locking block. That is, the staff adjusts the position of the flexible circuit board by sliding the slider 262 on the guide rail 261. After the adjustment is completed, the slider 262 is fixed by screwing the locking member 263 and the locking hole 264, thereby fixing the position of the rotating member 25 provided on the slider 262. This achieves the effect of flexible adjustment and adaptability to various TP screen assemblies.

[0038] In this embodiment, the pickup mechanism 3 includes a shell 31, a film-absorbing member 32, and a ventilation mechanism 33. The shell 31 is a hollow structure with an opening on one side. The open side of the shell 31 is mounted on the mounting seat 5. The ventilation mechanism 33 is arranged in the shell 31. The film-absorbing member 32 is located below the shell 31 and is connected to the ventilation mechanism 33. The ventilation mechanism 33 is used to supply air to the film-absorbing member 32. After the film-absorbing member 32 contacts the panel, negative pressure gas is introduced into the film-absorbing member 32 through the ventilation mechanism 33, and the panel is picked up by utilizing the pressure difference between the inside and the outside. The ventilation mechanism 33 is directly connected to the air supply mechanism 14 through a clearance hole, so that the air path is connected between the mounting plate 4 and the mounting seat 5, simplifying the air path. Specifically, the ventilation mechanism 33 is of a conventional structure, such as a solenoid valve, and is connected to the power connection mechanism through an electrical connection part, so that the drive control unit can send control instructions to it; and a suction cup 34 can be embedded in the bottom of the film suction member 32, and an air channel can be set in the film suction member 32, that is, the suction cup 34 is connected to the ventilation mechanism 33 through the air channel. After the film suction member 32 contacts the panel, the ventilation mechanism 33 inputs negative pressure gas into the suction cup 34 through the air channel, so that the suction cup 34 can suck the panel for picking up.
