[0029] The lifting assembly includes a square plate 401 that is slidably connected to the inner cavity of the square groove 109. Four groups of rubber sleeves 402 are provided on the surface of the square plate 401. The four groups of rubber sleeves 402 are arranged in a rectangular shape and are connected to the square plate 401 through connectors. Limiting holes 108 are provided on the surface of the operating table 100 and at positions corresponding to the rubber sleeves 402. The four groups of rubber sleeves 402 are respectively inserted into the inner cavity of the limiting holes 108. The tops of the four groups of rubber sleeves 402 are flush with the operating table 100. The inner cavity of the square groove 109 is provided with a pushing assembly for pushing the square plate 401 upward. The lifting assembly lifts the bound display screen upward to a suitable height, allowing staff to grab the display screen more easily, making it easier for staff to remove the display screen and reducing the difficulty and fatigue of the operation. In addition, the soft material of the rubber sleeves 402 can prevent the display screen from directly contacting the square plate 401, preventing the display screen surface from being scratched or damaged.

[0030] The clamping assembly includes a limiting groove 102 formed on the inner wall surface of the bottom of the U-shaped plate 101. A bidirectional screw 201 is rotatably connected to the inner cavity of the limiting groove 102. One end of the bidirectional screw 201 rotates through the U-shaped plate 101. The two ends of the bidirectional screw 201 are respectively threadedly connected to corresponding nut seats 202. The surfaces of the two sets of nut seats 202 are fixedly connected to the surfaces of the two sets of clamping blocks 200, and the two sets of clamping blocks 200 are respectively located on the inner walls of the U-shaped plate 101.

In addition, the configuration of the limiting groove 102 ensures the stable movement direction of the nut seats 202, thereby making the clamping more reliable.

[0031] The push assembly includes a cam 403 that is rotatably connected to the inner cavity of the square groove 109. The surface of the cam 403 contacts the surface of the square plate 401. A connecting rod 404 is fixedly connected to one side of the cam 403. One end of the connecting rod 404 rotates through the operating table 100 and is fixedly connected to a handwheel 405. With the configuration of the push assembly, the square plate 401 can be raised by turning the handwheel 405. The operation is simple and convenient, and the bound display screen can be quickly lifted up for easy access by staff.

[0032] It is worth noting that second springs 400 are fixedly installed on the top of both sides of the square plate 401, and the other ends of the second springs 400 are fixedly connected to the top inner wall of the square groove 109. Through the setting of the second springs 400, the second springs 400 on the top of both sides of the square plate 401 play a buffering role during the jacking process, preventing the square plate 401 from suddenly rising or falling and causing damage to the display screen, and when the jacking of the display screen is completed, the square plate 401 is pushed downward, so that the rubber sleeve 402 automatically retracts into the limiting hole 108.

[0033] The connector includes a sliding groove 500 formed on the surface of the square plate 401 and corresponding to each set of rubber sleeves 402. Sliders 502 are slidably connected to the inner cavity of the sliding groove 500. Bolts 501 are inserted into the inner cavity of each of the four sets of rubber sleeves 402. The four sets of bolts 501 extend downward through the rubber sleeves 402 and are threadedly connected to the surfaces of the corresponding sliders 502. The configuration of the connector, the sliding groove 500, the sliders 502, and the bolts 501 within the connector allow the rubber sleeves 402 to be adjusted as needed to accommodate display screens of different sizes. This also facilitates replacement and maintenance of the rubber sleeves 402, improving the maintainability of the device.

[0034] A receiving groove 107 is provided at the top of the operating table 100, corresponding to the centerline of the U-shaped plate 101. A guide rod 301 is fixedly connected to the inner cavity of the receiving groove 107. A guide sleeve 303 is slidably sleeved on the surface of the guide rod 301. A first spring 302 is sleeved on the surface of the guide rod 301. The two ends of the first spring 302 are respectively fixedly connected to the guide sleeve 303 and the surface of the receiving groove 107. The top of the guide sleeve 303 is fixedly connected to an abutment block 300, and the bottom of the abutment block 300 is slidably connected to the top surface of the operating table 100. The provision of the abutment block allows the display screen to be closely attached to the bottom inner wall of the U-shaped plate 101, facilitating the alignment of the crimping assembly with the position to be bound. At the same time, the provision of the first spring 302 allows for application to a variety of display screen models.

[0035] When the embodiment of the present invention is used, the abutment block 300 is first pulled to one side, and the guide sleeve 303 fixed at the bottom of the abutment block 300 slides along the guide rod 301 and compresses the first spring 302 at the same time. Then the display screen is placed in the inner cavity of the U-shaped plate 101 and abuts against the bottom inner wall of the U-shaped plate 101. At the same time, the pressing block 106 is aligned with the position where the display screen needs to be bound, and the chip to be bound is coated with conductive glue and placed on the display screen. The staff holds the abutment block 300, and the abutment block 300 is pushed by the first spring 302. , move to one side. When the abutment block 300 approaches the display screen, the staff holds the abutment block 300, makes it slowly contact the edge of the display screen, and rotates the bidirectional screw 201. The bidirectional screw 201 rotates and drives the two sets of clamping blocks 200 to move inward at the same time, thereby clamping the display screen to prevent the display screen from being displaced or shaken when binding the display screen. The telescopic end of the electric push rod 105 is controlled to extend upward to press the chip, apply a certain amount of pressure to the chip, so that the chip is in close contact with the display screen, and realize physical connection and circuit conduction.

[0036] When the binding is completed, the bidirectional screw 201 is rotated in the opposite direction to release the clamping of the display screen, and then the abutment block 300 is pulled outward. At this time, the handwheel 405 is turned, and the handwheel 405 drives the cam 403 to rotate through the connecting rod 404. During the rotation of the cam 403, the protruding part of the cam 403 gradually pushes the square plate 401 upward, and the square plate 401 is lifted upward along the square groove 109. The rubber sleeve 402 installed on the surface of the square plate 401 moves upward along the limiting hole 108 to lift the bound display screen, and then the staff takes the bound display screen.

[0037] When binding a smaller display screen, it is necessary to adjust the distance between two adjacent sets of rubber sleeves 402 to accommodate the display screen that needs to be bound. The staff uses tools to loosen the bolts 501 in sequence to release the restrictions on the rubber sleeves 402, move the rubber sleeves 402 inward, and adapt to the smaller display screen. Then, the bolts 501 are tightened so that one end of the bolt 501 abuts against the inner cavity of the sliding groove 500.

[0038] In the embodiment of the present invention, the main purpose of adjusting the pressure is to ensure good physical contact and circuit continuity between the chip and the display screen, while avoiding damage to the display screen or chip due to excessive pressure. The following is the specific principle and implementation of adjusting the pressure:

[0039] Pressure adjustment principle:

[0040] 1. Choice of stressor:

[0041] Electric linear actuator: This application uses an electric linear actuator as the primary pressure source. The electric linear actuator can be precisely adjusted through a controller to achieve precise control of the pressure.

[0042] 2. Pressure transmission mechanism:

[0043] Press-fit assembly: The press-fit assembly is mounted on the surface of the mounting block 104 and presses the chip through the telescopic end of the electric push rod 105. The design of the press-fit assembly needs to ensure that the pressure is evenly distributed across the entire chip surface to avoid damage to the chip due to excessive local pressure.

[0044] 3. Stress control strategies:

[0045] Closed-loop control system: The pressure value during the crimping process is monitored in real time by a sensor and fed back to the controller. The controller adjusts the extension and retraction of the electric push rod according to the set pressure value, thus achieving dynamic pressure regulation.

[0046] Preset pressure values: Different pressure values ​​are preset based on different chips and displays. These preset values ​​can be set during device initialization or manually adjusted before each binding.

[0047] Gradual pressurization: To avoid applying excessive pressure instantly, you can use a gradual pressurization method, that is, apply a small pressure value first, and then gradually increase it until the predetermined pressure value is reached.

[0048] 4. Pressure protection mechanism:

[0049] Overload protection: Set an overload protection mechanism. When the pressure exceeds the set maximum value, the electric push rod will automatically stop extending and retracting to prevent irreversible damage to the chip or display.

[0050] Soft landing: Use soft materials (such as rubber pads) on the contact surface of the press-fit component to reduce impact force and ensure gentle contact between the chip and the display.

[0051] Implementation:

[0052] 1. Electric linear actuator 105:

[0053] Controller: The controller receives pressure data from the sensor and adjusts the extension and retraction of the electric push rod according to the preset pressure value.

[0054] Sensor: A pressure sensor installed near the crimping assembly monitors pressure changes during the crimping process in real time.

[0055] Telescopic end: The telescopic end of the electric push rod is connected to the crimping assembly, and applies pressure to the chip through the telescopic action.

[0056] 2. Crimp assembly:

[0057] Pressing block 106: The pressing block 106 is installed at the telescopic end of the electric push rod 105 and is used to directly contact the chip and apply pressure.

[0058] Soft contact surface: The contact surface of the pressing block 106 is made of soft material to reduce the impact force on the chip.

[0059] 3. Control logic:

[0060] Initialization: When the device starts up, enter or select the appropriate pressure value through the user interface.

[0061] Real-time monitoring: During the crimping process, the sensor continuously monitors the pressure value and sends the data to the controller.

[0062] Dynamic adjustment: The controller dynamically adjusts the extension and retraction of the electric push rod based on real-time monitoring data to ensure that the pressure is always within the set range.

[0063] Abnormal handling: When the pressure exceeds the set range, the controller will trigger an alarm and stop the action of the electric push rod to prevent damage to the chip or display.

[0064] Through the above principles and implementation methods, it can be seen that the embodiment of the utility model can achieve precise control of pressure, ensure high-quality binding between the chip and the display screen, and minimize potential damage to the device.

[0065] In summary, the embodiment of the present invention is a COG binding head device with adjustable pressure. The bound display screen is lifted upward by the lifting component to a suitable height, so that the staff can grab the display screen more easily, which is convenient for the staff to take out the display screen and reduces the difficulty and fatigue of the operation. The soft material of the rubber sleeve 402 can avoid direct hard contact between the display screen and the square plate 401, and prevent the surface of the display screen from being scratched or damaged. At the same time, the sliding groove 500, slider 502 and bolt 501 structure in the connecting part enable the rubber sleeve 402 to be adjusted in position as needed to adapt to display screens of different sizes, and facilitate the replacement and maintenance of the rubber sleeve 402, thereby improving the maintainability of the equipment.
