Description

Technical Field

[0001] This utility model relates to the field of LCD screen processing, specifically to an LCD screen processing and sealing device. Background Technology

[0002] Currently, before the display screen is thinned, it needs to be sealed with glue to ensure the flatness of the edges. In order to ensure the product qualification rate, manual sealing of the display screen edges is required by machine. Existing equipment relies heavily on motor-driven automated equipment, which increases the difficulty of operating the equipment.

[0003] Chinese patent discloses a sealing device for LCD screen processing (authorization announcement number CN 220027580 U). This patented technology solves the problem that "traditional LCD screen sealing devices use two servo motors to control the spacing between adjustment plates and a third motor to adjust the movement of the glue sprayer, which not only increases the overall power burden of the device, but also increases the difficulty of operation by requiring users to constantly adjust the rotation and stopping of the motors, thus reducing the practicality of the device itself." However, the patent still has the following problems:

[0004] The patent uses a clamping method to fix the LCD screen. This method can easily damage the LCD screen casing during clamping and requires disassembly of the clamp, which reduces work efficiency. Furthermore, there is a certain distance between the sealing head and the LCD screen surface, which can easily lead to positional deviation and side leakage. Utility Model Content

A first slider is installed on the upper surface of the worktable by means of sliding fit. A base plate is installed on the upper surface of the first slider. An adjusting seat is rotatably installed on the upper surface of the base plate by means of a bearing. The positioning cavity is screwed to the upper surface of the adjusting seat by a first screw. A fixed seat is installed on the upper surface of the worktable. An electric slider is installed at the top of the fixed seat. A connecting seat is installed at the bottom of the electric slider. A sealing machine is installed at the bottom of the connecting seat. A sealing head is installed at the bottom of the sealing machine. A control panel is installed on the left end face of the fixed seat. The electric slider and the control panel are electrically connected.

[0006] Preferably, the bottom plate has multiple support heads installed on its upper surface, a positioning cavity is arranged above the support heads, and outer positioning plates are symmetrically installed on the left and right side walls of the bottom plate.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0019] Please see Figures 1-5 This embodiment provides a liquid crystal screen processing and sealing device, including a worktable 1 and a positioning cavity 2. A first slider 11 is slidably mounted on the upper surface of the worktable 1. A base plate 12 is mounted on the upper surface of the first slider 11. An adjusting seat 13 is rotatably mounted on the upper surface of the base plate 12 via a bearing. The positioning cavity 2 is screwed to the upper surface of the adjusting seat 13 via a first screw 14. A fixed seat 15 is mounted on the upper surface of the worktable 1. An electric slider 16 is mounted on the top of the fixed seat 15. A connecting seat 19 is mounted on the bottom of the electric slider 16. A sealing machine 17 is mounted on the bottom of the connecting seat 19. A sealing head is mounted on the bottom of the sealing machine 17. A control panel 18 is mounted on the left side of the fixed seat 15. The electric slider 16 and the control panel 18 are electrically connected. The control panel 18 contains a PCL program to control the operation of each device. The electric slider 16 is a linear guide slider structure. The motor drives the lead screw to control the linear movement of the device, placing the LCD screen in the corresponding positioning cavity 2 for limiting. Compared with the clamping and fixing method, this avoids damage to the LCD screen shell during clamping and eliminates the need to disassemble the clamp, thus improving work efficiency. The front and back positions of the LCD screen are adjusted by moving the base plate 12 back and forth. The electric slider 16 is started, driving the sealing machine 17 to move left and right, thereby enabling sealing of LCD screens in different positions. The first screw 14 structure facilitates the disassembly and replacement of the positioning cavity 2, allowing for the placement and processing of LCD screens of different specifications.

[0020] Multiple support heads 21 are installed on the upper surface of the base plate 12. A positioning cavity 2 is arranged above the support head 21. External positioning plates are symmetrically installed on the left and right side walls of the base plate 12. The external positioning plates are connected to the left and right side walls of the positioning cavity 2 by means of a second screw 22. During operation, the support head 21 plays a supporting and fixing role on the bottom of the positioning cavity 2. The use of the second screw 22 structure further improves the limiting and fixing effect on the positioning cavity 2.

[0021] An annular plate 23 is arranged below the sealing head, and a connecting sleeve 24 is installed at the bottom of the annular plate 23. A connector 25 is installed on the inner side wall of the connecting sleeve 24 through a sliding fit. A base rod 26 is installed at the bottom of the connector 25, and a cotton pad is installed at the bottom of the base rod 26. A pin 27 is installed on the upper surface of the connector 25. During operation, the sealing head is a certain distance away from the LCD screen. The connector 25 moves down, so that the cotton pad is attached to the surface of the LCD screen, which facilitates the positioning of the sealing head and avoids the glue from leaking due to positional displacement. When the sealing head is blocked, the connector 25 moves up, and the pin 27 moves up, thereby clearing the blockage of the sealing head.

[0022] A side seat 28 is installed on the right end face of the connecting seat 19. A positioning spring rod 29 is installed at the bottom of the side seat 28 by means of sliding fit. An annular plate 23 is installed at the bottom of the positioning spring rod 29. During operation, the annular plate 23 is moved to the right, and the positioning spring rod 29 causes the annular plate 23 to move upward, so as not to affect the normal operation of the glue head.

[0023] In actual operation, the LCD screen is placed in the corresponding positioning cavity 2 for limiting treatment. Compared with the clamping and fixing method, this avoids damage to the LCD screen shell during clamping and eliminates the need to disassemble the clamp, thus improving work efficiency. The front and back positions of the LCD screen are adjusted by moving the base plate 12 back and forth. The electric slider 16 is started, driving the sealing machine 17 to move left and right, thereby enabling sealing treatment of LCD screens in different positions. The first screw 14 structure facilitates the disassembly and replacement of the positioning cavity 2, thus enabling the placement and processing of LCD screens of different specifications.
