[0026] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0028] like Figures 1-2 As shown, this application provides a display module dispensing device, including a platform 1, on which a dispensing component 2 is disposed. The dispensing component 2 is used for dispensing the display module, specifically:

[0029] The dispensing assembly 2 includes two sets of brackets 201 fixedly installed on the platform 1. A first moving module 21 is fixedly installed on both sets of brackets 201. The first moving module 21 uses existing ball screws and linear guides as transmission mechanisms and a drive device as a power source. The drive device can be an electric motor or a hydraulic motor. The specific structure and working principle are existing technologies and will not be described in detail here. For ease of explanation, the direction of movement of the first moving module 21 is defined as the X-axis.

[0030] The output end of the first moving module 21 is vertically provided with a second moving module 22 so that the second moving module 22 can move in the X-axis direction under the drive of the moving module, and the moving direction of the second moving module 22 is vertical. For ease of explanation, the moving direction of the second moving module 22 is defined as the Z-axis.

[0031] Continue to refer to Figure 2 It should be noted that the second moving module 22 has a fixed plate 224, which is connected to the output end of the first moving module 21. A servo motor 222 is installed on one side of the fixed plate 224, and a belt assembly (not shown in the figure) is fixedly installed on the output end of the servo motor 222. The belt assembly is installed on the fixed plate 224, and a sliding plate 221 is provided on the belt assembly. At the same time, a slide rail 223 is installed on the fixed plate 224. The sliding plate 221 is slidably disposed on the slide rail 223. Thus, under the drive of the servo motor 222, the sliding plate 221 is driven by the belt assembly to move up and down on the slide rail 223.

[0032] A pad 24 is fixedly installed on the skateboard 221. A dispensing device 23 is detachably installed on the pad 24. The dispensing device 23 has a dispensing needle 231 so that glue can be sprayed from the dispensing needle 231. Driven by the first moving module 21 and the second moving module 22, the dispensing device 23 can move in the X-axis and Z-axis directions to perform dispensing operations.

[0033] A third mobile module 26 is installed on platform 1. The structural components and driving method of the third mobile module 26 are the same as those of the first mobile module 21, with only slight differences in position and size. Therefore, the structure and principle of the second mobile module 22 will not be described in detail here.

[0034] Continue to refer to Figure 1 The output end of the third moving module 26 is fixedly mounted with a carrier plate 25 to facilitate the placement of the display module to be glued. Under the drive of the third moving module 26, the carrier plate 25 is moved synchronously. The direction of the third moving module 26 is perpendicular to the moving direction of the first moving module 21. For ease of explanation, the moving direction of the third moving module 26 is defined as the Y-axis, thereby driving the carrier plate 25 to move in the Y-axis direction.

[0035] During dispensing, the display module is placed on the carrier plate 25, and then the dispensing operation is performed on the display module through the cooperation of the first moving module 21, the second moving module 22 and the third moving module 26.

[0036] It should be noted that two sets of through slots 27 are provided on the support plate 25 so that when the display module is placed on the support plate 25, part of it will be suspended in the air, which makes it easier to pick up and put down the display module.

[0037] A protective component 3 is provided on the dispensing needle 231, which is used to protect the dispensing needle 231.

[0038] like Figures 2-3 As shown, the protective component 3 includes a sleeve 33 that is slidably sleeved on the outer peripheral surface of the dispensing needle 231. The sleeve 33 has multiple sets of vertical grooves (not shown in the figure) inside. A boss is slidably provided inside the vertical groove. A connecting rod 34 is fixedly installed at the bottom of the boss. The bottom of the connecting rod 34 passes through the bottom of the sleeve 33 so that the boss can slide up and down inside the vertical groove and simultaneously drive the connecting rod 34 to slide.

[0039] A sheath 35 is fixedly installed at the bottom of the connecting rod 34. A spring is provided between the sheath 35 and the connecting rod 34. The spring is sleeved on the outside of the connecting rod 34. The sheath 35 has a cylindrical part and a conical part 36. The dispensing needle 231 is located in the cylindrical part. Both the cylindrical part and the conical part 36 have through holes. When the dispensing needle 231 sprays glue, it can be sprayed through the through holes, thereby guiding the glue.

[0040] Furthermore, during the dispensing process, when encountering a protrusion during the translational dispensing process, the protrusion can press the conical part 36, causing the position of the sheath 35 to change, thereby compressing the spring until the sheath 35 passes the protrusion and returns to its original position under the action of the spring's restoring force, thus preventing the dispensing needle 231 from directly colliding with the protrusion and causing damage.

[0041] It should be noted that the sleeve 33 is provided with an elastic clamping piece 32, and a threaded sleeve 31 is threadedly installed on the elastic clamping piece 32;

[0042] In the initial state, the threaded sleeve 31 is threaded onto the elastic clamp 32. At this time, the threaded sleeve 31 restricts the elastic clamp 32, thereby fixing the sleeve 33 onto the dispensing needle 231. After long-term use, when the dispensing needle 231 and the protective sleeve 35 need to be cleaned, the threaded sleeve 31 is rotated. The threaded sleeve 31 gradually moves downward along the axis of the sleeve 33. The threaded sleeve 31 loses its restriction on the elastic clamp 32. At this time, the elastic clamp 32 assembly gradually bursts open in all directions, so that the sleeve 33 can be separated from the dispensing needle 231. Then the protective assembly 3 can be removed.

[0043] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
