[0031] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings:

[0032] Please refer to Figure 2 as well as Figure 3 The utility model provides a glue dispensing device for liquid crystal display production, comprising a conveying component 1 for conveying an assembly of a liquid crystal display B and a pin A placed obliquely, a guide member 2 arranged on the conveying component 1 for guiding the assembly of the liquid crystal display B and the pin A, a detection member 3 arranged on the conveying component 1 for detecting the connection between the liquid crystal display B and the pin A, and a glue dispensing gun 4 arranged on the conveying component 1 for applying glue to the connection between the liquid crystal display B and the pin A.

[0033] Specifically, the conveying assembly 1 includes a conveying frame 11, two conveying rollers 12, a conveying belt 13 and a conveying motor 14. The two conveying rollers 12 are arranged in parallel on the conveying frame 11. The conveying belt 13 is wound around the two conveying rollers 12. The conveying motor 14 is arranged on the conveying frame 11, and the output end of the conveying motor 14 is connected to one of the two conveying rollers 12.

[0034] In a specific application, the conveying motor 14 drives the conveying roller 12 connected to its output end to rotate, and the conveying roller 12 drives the conveyor belt 13 to rotate. The worker places the assembly of the LCD screen B and the pin A on the conveyor belt 13 one by one and tilts it. The conveyor belt 13 conveys the assembly of the LCD screen B and the pin A toward the dispensing gun 4. During the conveying process, the guide part 2 guides the assembly of the LCD screen B and the pin A, and the detection part 3 detects the connection between the LCD screen B and the pin A. The detection part 3 feeds back the detection signal to the control system of the dispensing device for the production of the LCD screen. The control system controls the dispensing gun 4 to accurately apply glue at the connection between the LCD screen B and the pin A, so that the LCD screen B and the pin A are firmly connected.

[0035] It should be noted that the workers place the assembly of the LCD screen B and the pin A one by one at an angle on the conveyor belt 13, which means that the workers place the assembly of the LCD screen B and the pin A one by one at an angle in an inverted "V" shape on the conveyor belt 13, and the side of the LCD screen B opposite to the pin A abuts against the guide member 2.

[0036] In some preferred embodiments, the above-mentioned glue dispensing device for producing liquid crystal display screens further includes a longitudinal adjustment component 5, which is arranged on the conveying component 1, and the detection component 3 and the glue dispensing gun 4 are both arranged on the longitudinal adjustment component 5. In specific applications, by arranging the longitudinal adjustment component 5 on the conveying component 1, the detection component 3 and the glue dispensing gun 4 can be adjusted in the longitudinal direction, so that the detection component 3 and the glue dispensing gun 4 can detect and dispense glue on liquid crystal display screens B of different specifications.

[0037] For details, please refer to Figure 4The longitudinal adjustment assembly 5 includes a gantry 51, a fixed plate 52, a first movable plate 53, a second movable plate 54, a connecting rod 55 and an adjusting rod 56. The gantry 51 is straddled on the conveying assembly 1. The fixed plate 52 is arranged on the gantry 51. The first movable plate 53 and the second movable plate 54 are respectively arranged above and below the fixed plate 52, and the detection member 3 and the dispensing gun 4 are both arranged on the second movable plate 54. The connecting rod 55 passes through the fixed plate 52, and the two ends of the connecting rod 55 are respectively connected to the first movable plate 53 and the second movable plate 54. One end of the adjusting rod 56 passes through the first movable plate 53 and abuts against the fixed plate 52. In a specific application, the adjusting rod 56 is a screw rod. By rotating the adjusting rod 56, the length of the adjusting rod 56 between the fixed plate 52 and the first movable plate 53 can be changed. When the length of the adjusting rod 56 between the fixed plate 52 and the first movable plate 53 increases, the first movable plate 53 drives the second movable plate 54 to move upward through the connecting rod 55, thereby driving the detection part 3 and the dispensing gun 4 to move upward to adapt to a larger LCD screen B. Conversely, when the length of the adjusting rod 56 between the fixed plate 52 and the first movable plate 53 decreases, the first movable plate 53 drives the second movable plate 54 to move downward through the connecting rod 55, thereby driving the detection part 3 and the dispensing gun 4 to move downward to adapt to a smaller LCD screen B.

[0038] In some preferred embodiments, the longitudinal adjustment assembly 5 further includes a guide sleeve 57, which is disposed on the fixed plate 52 and sleeved on the connecting rod 55. In specific applications, when the first movable plate 53 drives the second movable plate 54 to move, the guide sleeve 57 can not only play a guiding role, but also reduce the friction between the connecting rod 55 and the fixed plate 52, thereby reducing wear.

[0039] In some preferred embodiments, the second movable plate 54 is provided with a lateral adjustment component 6, and the detection member 3 and the glue gun 4 are both arranged on the lateral adjustment component 6. In specific applications, by arranging the lateral adjustment component 6 on the second movable plate 54, the detection member 3 and the glue gun 4 can be adjusted in the lateral direction, so that the detection member 3 and the glue gun 4 can accurately correspond to the connection between the liquid crystal display screen B and the pin A, so as to ensure the detection accuracy and the glue dispensing accuracy.

[0040] For details, please refer to Figure 5In some preferred embodiments, the lateral adjustment assembly 6 includes a mounting plate 61, a guide rail 62, a slider 63 and a mounting block 64; the mounting plate 61 is disposed on the second movable plate 54; the guide rail 62 is disposed on the mounting plate 61; the slider 63 is slidably disposed on the guide rail 62; the mounting block 64 is connected to the slider 63, and the detection member 3 and the glue gun 4 are both disposed on the mounting block 64. In a specific application, the slider 63 drives the mounting block 64 to slide along the guide rail 62, thereby driving the detection member 3 and the glue gun 4 to move, so as to achieve lateral adjustment of the detection member 3 and the glue gun 4.

[0041] In some preferred embodiments, the lateral adjustment assembly 6 further includes a fixing rod 65, and a long hole 611 is provided on the mounting plate 61. One end of the fixing rod 65 passes through the long hole 611 and the slider 63 to movably abut against the guide rail 62. In a specific application, the fixing rod 65 is a screw rod. By rotating the fixing rod 65 so that one end thereof abuts against the guide rail 62, the slider 63 can be relatively fixed to the guide rail 62, thereby achieving the fixation of the mounting block 64. When it is necessary to adjust the lateral position of the detection member 3 and the dispensing gun 4, the fixing rod 65 is rotated so that one end thereof does not abut against the guide rail 62. At this time, the slider 63 can slide equivalent to the guide rail 62. During the sliding process of the slider 63, the long hole 611 can guide the fixing rod 65.

[0042] In some preferred embodiments, the mounting block 64 is provided with a mounting groove 641, and the detection element 3 is installed in the mounting groove 641. In specific applications, by providing the mounting groove 641 on the mounting block 64, it is convenient to quickly install the detection element 3 at a predetermined position on the mounting block 64. Specifically, the detection element 3 can be an infrared sensor.

[0043] In some preferred embodiments, the diameter of the installation groove 641 gradually decreases from top to bottom. In specific applications, by designing the diameter of the installation groove 641 to gradually decrease from top to bottom, when the detection member 3 is installed, the inner side wall of the installation groove 641 can guide the detection member 3 inserted from top to bottom, so that the detection member 3 can be accurately installed in the installation groove 641.

[0044] In specific applications, the above-mentioned transmission component 1, detection component 3 and dispensing gun 4 are all electrically connected to the control system of the dispensing device for producing liquid crystal display screens. The control system of the dispensing device for producing liquid crystal display screens controls the movement of the transmission component 1, detection component 3 and dispensing gun 4 to achieve the effect of automatic control of the dispensing device for producing liquid crystal display screens. Of course, the control system of the dispensing device for producing liquid crystal display screens can be any one of an industrial computer, a PLC or a single-chip microcomputer, which will not be described in detail here.

[0045] In summary, the glue dispensing device for LCD screen production of the present invention guides the assembly of the LCD screen B and the pin A transmitted by the transmission component 1 through the guide member 2, and detects the connection between the LCD screen B and the pin A through the detection member 3, so that the glue dispensing gun 4 can accurately apply glue to the connection between the LCD screen B and the pin A, which not only improves the glue dispensing efficiency, but also ensures the quality of glue dispensing, thereby ensuring the quality of the product.

[0046] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention shall be included in the scope of the claims of the present invention.
