Description

Technical Field

[0001] The utility model relates to the field of LCD liquid crystal panel processing, in particular to an IC attaching device for LCD liquid crystal panels. Background Art

[0002] An LCD screen consists of liquid crystals placed between two parallel pieces of glass. There are many tiny vertical and horizontal wires between the two pieces of glass. The flow of electricity controls the direction of the rod-shaped crystal molecules, refracting light to produce an image. An IC chip is an integrated circuit made of a large number of microelectronic components (transistors, resistors, capacitors, etc.) placed on a plastic substrate to form a chip. When attaching the IC chip to the LCD panel terminal, a pressing method is used to improve the adhesion and make it adhere more firmly.

[0003] Currently, when attaching ICs to LCD panels, it is necessary to first apply bidirectional conductive adhesive to the LCD display mounting area, then attach the ICs one by one to the bidirectional conductive adhesive, and finally press the ICs together using a dedicated device. However, manually placing the ICs in specific positions is imprecise and time-consuming, which prevents the subsequent pressing work from being carried out in a timely manner, resulting in poor attachment results.

[0004] To this end, an IC attaching device for LCD liquid crystal panel is proposed. Utility Model Content

[0005] In view of the above problems, the present invention provides an IC attaching device for LCD liquid crystal panel to solve the problems raised in the above background technology.

[0006] The technical solution of the utility model is:

[0007] The top end of the guide box is fixedly connected to the bottom end of the guide box, and the bottom end of the guide box is fixedly connected to the bottom end of the guide box. The IC is equidistantly laid on the inner wall of the guide groove, and the inner wall of the guide groove at one end away from the guide box is provided with a drop groove, and the drop groove is opposite to the telescopic end of the hydraulic push rod. The bottom end of the guide box is provided with a through opening facing the hydraulic push rod, and the end of the guide box away from the hydraulic push rod is provided with a socket, and a push plate is inserted into the inner wall of the socket, and the side wall of the guide box is provided with a first electric telescopic rod, and the telescopic end of the first electric telescopic rod is fixedly connected to the push plate.

[0008] The working principle of the above technical solution is as follows:

[0009] Insert the chip box containing IC chips into the second mounting port of the horizontal plate, and then lay the IC chips evenly on the inner wall of the guide groove of the lead-out box at the bottom of the chip box. Then start the first electric telescopic rod, and the telescopic end of the first electric telescopic rod pushes the push plate. The push plate is inserted into the lead-out box through the socket, pushing the IC chips in the guide groove away from the socket. When the IC chips are pushed to the end of the guide groove away from the chip box, they reach the drop groove position. At this time, the drop groove is opposite to the telescopic end of the hydraulic push rod, waiting for the hydraulic push rod to move and perform the IC attachment operation.

[0010] In a further technical solution, threaded rods and sliding rods are respectively installed on both sides of the workbench through bearing frames, and a motor is provided at the front end of the workbench. The output end of the motor is fixedly connected to the end of the threaded rod, and a threaded opening threadedly connected to the threaded rod is opened at the bottom end of one of the support columns, and a sliding opening slidably connected to the sliding rod is opened at the bottom end of the other support column.

[0011] Through the above technical solution, it is possible to adapt to LCD panels of different sizes. When facing LCD panels of different specifications, the position of the support column is adjusted by the motor, and then the position of the horizontal plate and the patch box and hydraulic push rod thereon are adjusted, so that the device can flexibly perform IC attachment operations on panels of various sizes, thereby improving the applicability of the device.

[0012] In a further technical solution, screw holes are provided on the side walls of the horizontal plate and the surface of the patch box, and bolts are threadedly connected to the inner walls of the screw holes.

[0013] With the above technical solution, the patch box can be firmly fixed on the horizontal plate through the threaded connection between the bolts and the screw holes. When the patch box needs to be replaced or repaired, the patch box can be removed from the horizontal plate by simply unscrewing the bolts.

[0014] In a further technical solution, a symmetrically arranged second electric telescopic rod is embedded in the top end of the support column, and the telescopic end of the second electric telescopic rod is fixedly connected to the bottom surface of the end of the horizontal plate.

[0015] Through the above technical solution, the position of the horizontal plate can be easily raised, so that the initial positions of the hydraulic push rod and the patch box can be adjusted higher, making it convenient to adjust the placement position of the LCD panel.

[0016] In a further technical solution, a symmetrical fixing block is fixedly connected to the surface of the shell of the first electric telescopic rod, and the side wall of the fixing block is fixedly connected to the surface of the lead-out box.

[0017] Through the above technical solution, the first electric telescopic rod can be firmly fixed to the surface of the lead-out box through the symmetrical fixing blocks.

[0018] In a further technical solution, a fixing plate is welded to the outer surface of the motor, and the fixing plate is detachably mounted on the outer surface of the workbench.

[0019] The above technical solution can provide a stable support for the motor, preventing the motor from being displaced or shaken due to vibration or external force during operation.

[0020] In a further technical solution, the diameter of the telescopic end of the hydraulic push rod is smaller than the diameter of the drop groove.

[0021] Through the above technical solution, when the diameter of the telescopic end of the hydraulic push rod is smaller than the diameter of the drop groove, the telescopic end of the hydraulic push rod can smoothly pass through the drop groove to press down and attach the IC piece, avoiding the jamming and obstruction caused by the mismatch between the telescopic end and the drop groove size, and ensuring the smooth progress of the attachment process.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] By arranging an IC chip inside the patch box and pushing the first electric telescopic rod, the IC chip inside the guide groove can be pushed toward the drop groove, and then the IC inside the patch box can fall. When the IC chip is located at the drop groove, the extension of the hydraulic push rod can press the IC chip down on the LCD panel on the top surface of the workbench, and at the same time have a downward pressing effect.

The telescopic end of the first electric telescopic rod 13 is fixedly connected to the push plate 12.

[0035] The working principle of the above technical solution is as follows:

[0036] Insert the chip box 6 containing the IC chip into the second mounting port 5 of the horizontal plate 3, and then lay the IC chip evenly spaced on the inner wall of the guide groove 9 of the lead-out box 8 at the bottom of the chip box 6. Then start the first electric telescopic rod 13. The telescopic end of the first electric telescopic rod 13 pushes the push plate 12. The push plate 12 is inserted into the lead-out box 8 through the socket 11, pushing the IC chip in the guide groove 9 in the direction away from the socket 11. When the IC chip is pushed to the end of the guide groove 9 away from the chip box 6, it reaches the position of the drop groove 15. At this time, the drop groove 15 is opposite to the telescopic end of the hydraulic push rod 7, waiting for the hydraulic push rod 7 to move and perform the IC attachment operation.

[0037] See also Figure 1 and Figure 2 , threaded rods 17 and sliding rods 19 are respectively installed on both sides of the workbench 1 through bearing frames. A motor 16 is provided at the front end of the workbench 1. The output end of the motor 16 is fixedly connected to the end of the threaded rod 17. A threaded opening 18 threadedly connected to the threaded rod 17 is opened at the bottom end of one of the support columns 2, and a sliding opening 20 slidingly connected to the sliding rod 19 is opened at the bottom end of the other support column 2.

[0038] It can adapt to LCD panels of different sizes. When facing LCD panels of different specifications, the position of the support column 2 is adjusted by the motor 16, and then the position of the horizontal plate 3 and the patch box 6 and hydraulic push rod 7 thereon are adjusted, so that the device can flexibly perform IC attachment operations on panels of various sizes, thereby improving the applicability of the device.

[0039] See also Figure 3 and Figure 4 The side wall of the horizontal plate 3 and the surface of the patch box 6 are both provided with screw holes 22, and the inner wall of the screw hole 22 is threadedly connected with a bolt 23.

[0040] The patch box 6 can be firmly fixed on the horizontal plate 3 through the threaded connection between the bolts 23 and the screw holes 22. When the patch box 6 needs to be replaced or repaired, the patch box 6 can be removed from the horizontal plate 3 by simply unscrewing the bolts 23.

[0041] See also Figure 1 and Figure 3 The top end of the support column 2 is embedded with a symmetrically arranged second electric telescopic rod 24, and the telescopic end of the second electric telescopic rod 24 is fixedly connected to the bottom surface of the end of the horizontal plate 3.

[0042] The height of the horizontal plate 3 can be quickly adjusted by the second electric telescopic rod 24, thereby ensuring that the hydraulic push rod 7 and the patch box 6 can match liquid crystal panels of different heights, thereby improving the applicability of the device.

[0043] See also Figure 1 and Figure 4A symmetrical fixing block 14 is fixedly connected to the shell surface of the first electric telescopic rod 13 , and the side wall of the fixing block 14 is fixedly connected to the surface of the outlet box 8 .

[0044] The first electric telescopic rod 13 can be firmly fixed to the surface of the lead-out box 8 by means of the symmetrical fixing block 14 .

[0045] See also Figure 1 and Figure 2 A fixing plate 21 is welded on the outer surface of the motor 16 , and the fixing plate 21 is detachably mounted on the outer surface of the workbench 1 .

[0046] It can provide stable support for the motor 16 to prevent the motor 16 from being displaced or shaken due to vibration or external force during operation.

[0047] See also Figure 1 and Figure 2 The diameter of the telescopic end of the hydraulic push rod 7 is smaller than the diameter of the drop groove 15.

[0048] When the diameter of the telescopic end of the hydraulic push rod 7 is smaller than the diameter of the drop groove 15, the telescopic end of the hydraulic push rod 7 can smoothly pass through the drop groove 15 to press down and attach the IC sheet, avoiding jamming and obstruction caused by the mismatch between the size of the telescopic end and the drop groove 15, and ensuring the smooth progress of the attachment process.

[0049] During operation, the LCD panel to be attached with IC is placed at a suitable position on the workbench 1, and the motor 16 is started. The motor 16 drives the threaded rod 17 to rotate. Since the bottom end of one of the support columns 2 is threadedly connected to the threaded rod 17 through the threaded opening 18, and the bottom end of the other support column 2 is slidably connected to the slide rod 19 through the sliding opening 20, the horizontal position of the support column 2 and the cross plate 3 can be adjusted to align with the attachment position on the LCD panel. The second electric telescopic rod 24 is started to raise the position of the cross plate 3, so that the initial position of the hydraulic push rod 7 and the patch box 6 is adjusted to facilitate further adjustment of the placement position of the LCD panel. Subsequently, the patch box 6 is fixedly connected to the cross plate 3 through the bolt 23 to ensure that the patch box 6 is firmly installed, and the IC pieces are evenly spaced and flatly laid on the inner wall of the guide groove 9 of the lead-out box 8 at the bottom of the patch box 6. At this time, the attachment and pressing work can be carried out: the first electric telescopic rod 13 is started, and the first electric telescopic rod 13 pushes the IC piece inside the guide groove 9 toward the drop groove 15 through the push plate 12. When the frontmost IC piece reaches the drop groove 15, the IC inside the patch box 6 automatically falls under the action of gravity and is replenished into the guide groove 9. Then the hydraulic push rod 7 is started. Since the diameter of the telescopic end of the hydraulic push rod 7 is smaller than the diameter of the drop groove 15, the telescopic end of the hydraulic push rod 7 passes through the drop groove 15 and presses down the IC piece located at the drop groove 15, so that it is attached to the LCD liquid crystal panel on the top surface of the workbench 1, completing one IC attachment operation.

[0050] The above-described embodiments merely represent specific implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
