Description

Technical Field

[0001] This invention relates to the field of display screen manufacturing equipment, and more particularly to a display screen dispensing device. Background Technology

[0002] During the manufacturing process of LED displays, glue needs to be evenly applied to the four edges of the LED display shell to bond the display screen. Patent application number CN202221366735.2 discloses a dispensing device for LED displays, including a support base. Vertical plates are fixed to both ends of the top of the support base. T-shaped movable rods penetrate the inner cavities of both sets of vertical plates. Clamping plates are installed on the side of each of the four sets of T-shaped movable rods near the center of the support base. The display screen body is positioned between the two sets of clamping plates. Return springs are sleeved on the outer walls of the four sets of T-shaped movable rods, located between the clamping plates and the vertical plates. A top plate connects the two sets of vertical plates. A horizontal translation component is installed at the bottom of the top plate. A vertical translation component is installed at the bottom of the horizontal translation component. An electric push rod is installed at the bottom of the vertical translation component, and a dispensing component is installed at the output end of the electric push rod. The display screen body is clamped by two sets of clamping plates. After the display screen body is clamped, the dispensing component is driven to move by the horizontal translation component and the vertical translation component to perform dispensing operation on the display screen. However, this type of dispensing device dispenses glue to the display screen with a single dispensing needle. After the display screen is placed, it is necessary to wait for the glue to be dispensed on the four edges of the display screen. After the glue is completed, the workpiece can be removed before the next glue dispensing can be performed, resulting in low production efficiency of the display screen.

[0003] This invention was proposed in response to the shortcomings of existing technologies. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a display screen dispensing device.

[0005] This invention can be achieved through the following technical solutions:

[0006] This invention discloses a display screen dispensing device, comprising a base plate, a rotary motor fixed on the base plate, a turntable fixed at the output end of the rotary motor, a plurality of fixing slots evenly arranged on the turntable, and a dispensing mechanism disposed at a corresponding position above each fixing slot. The dispensing mechanism includes a support plate fixed on the base plate, a lead screw and a slide rod disposed on the support plate, the lead screw being driven to rotate by the dispensing motor, and a slider threadedly connected to the lead screw, the slide rod passing through the slider and slidably connected to the slider, a dispensing cylinder fixed on each slider, a fixing block fixed at the end of the piston rod of each dispensing cylinder, and a glue tube fixed on each fixing block. The display screen to be glued is placed in the fixed slot of the turntable. The corresponding glue dispensing cylinder is activated, the piston rod on the glue dispensing cylinder extends, the glue tube descends, and the glue needle at the bottom of the glue tube reaches the designated position. The corresponding glue dispensing motor drives the lead screw to rotate, and the glue needle dispenses glue along one edge of the display screen. After the glue dispensing is completed, the glue dispensing cylinder is activated, the piston rod on the glue dispensing cylinder shortens, the glue tube rises, and the glue dispensing motor drives the lead screw to rotate in the opposite direction, the slider returns to the initial position, and the rotary motor drives the turntable to rotate a certain angle. The display screen with glued along one edge moves to the next glue dispensing mechanism position, and another display screen to be glued is placed in a fixed slot on the turntable. This cycle is repeated. This device can perform glue dispensing operations on display screens. When the device is running stably, it can apply glue to the edges of multiple display screens at once. Each glue tube applies glue to a corresponding edge of the display screen, eliminating the need to wait for the previous display screen to finish applying glue before applying glue to the next display screen, greatly improving the production efficiency of display screens.

[0007] Preferably, each of the fixed slots is provided with a positioning slot, each positioning slot is provided with a positioning block, each positioning block has a positioning rod fixed to its bottom, the positioning rod passes through the turntable and is slidably connected to the turntable, each positioning rod has a limit block fixed to its bottom, each limit block has a spring fixed between it and the turntable, and a limit cylinder is also fixed to the base plate, with a support plate fixed to the end of the piston rod of the limit cylinder. After the glue is applied to the upper edge of the display screen, the display screen reaches the position of the support plate, the limit cylinder is activated, the piston rod on the limit cylinder extends, the support plate rises, and after the support plate contacts the limit block, it pushes the limit block to rise. The positioning block rises with the limit block, and the positioning block pushes the display screen out of the fixed slot and removes the display screen. After the display screen is removed, the limit cylinder is activated, the piston rod on the limit cylinder shortens, the positioning block descends, the positioning block returns to the positioning slot, and the display screen to be glued is placed in the fixed slot again.

[0008] Compared with existing technologies, the present invention has the following advantages:

[0009] Once the device is running stably, it can apply glue to the edges of multiple displays at once. Each glue tube applies glue to a corresponding edge of the display, eliminating the need to wait for the previous display to finish applying glue before applying glue to the next display, which greatly improves the production efficiency of the displays.
