DETAILED DESCRIPTION

[0022] The principles and characteristics of the present application are described below in conjunction with the accompanying drawings, and the examples are used to explain the present application and are not intended to limit the scope of the present application.

[0023] It should be noted that, unless otherwise explicitly specified and limited, the terms "mounting", "connecting", "connecting" should be broadly understood, for example, it can be fixedly connected, or it can be detachably connected, or it can be an integrally formed structure. For ordinary skilled in the art, the specific meaning of such terms in this patent can be understood according to the specific circumstances.

[0024] As shown in Figure 1 and Figure 2 The utility model discloses a fiber optic jumper ceramic ferrule automatic glue injection device, including the chassis 1, two groups of opposite support seat 2 are arranged on the chassis 1, the support seat 2 is arranged on the ferrule tray 3 and the tray moving assembly 4 that is connected with the ferrule tray 3, the ferrule tray 3 is equipped with the ferrule positioning plate 5, the tray moving assembly 4 is used to drive the ferrule tray 3 to move to drive the ferrule positioning plate 5 preloaded on the ferrule to enter and exit the glue injection area, the chassis 1 is also arranged with the moving frame 6 in the glue injection area, the moving frame 6 is provided with the glue injection seat 7, and the transverse moving assembly 8 and longitudinal moving assembly 9 that are connected with the glue injection seat 7, the glue injection seat 7 is equipped with the glue injection head 7.1, and the lifting assembly 10 that is connected with the glue injection head 7.1.

[0025] As an implementation manner, the board surface of the ferrule positioning plate 5 is reserved with a plurality of ferrule fixing holes arranged in an array. The design of these fixing holes aims to accurately position and fix the ferrule, ensuring that the ferrule can maintain a stable position and posture during the glue injection process.

[0026] As an implementation manner, the tray moving assembly 4 includes:

[0027] The conveying belt 4.1 is arranged along the moving direction of the ferrule tray 3;

[0028] The electric drive wheel set 4.2 is drivingly connected with the conveying belt 4.1.

[0029] In this embodiment, the tray moving assembly 4 is mainly composed of the conveying belt 4.1 and the electric drive wheel set 4.2. The conveying belt 4.1 is laid along the moving direction of the ferrule tray 3, forming a continuous conveying path. The electric drive wheel set 4.2 is drivingly connected with the conveying belt 4.1, serving as a power source to drive the operation of the belt.

[0030] When the electric drive wheel set 4.2 is started, it will drive the conveying belt 4.1 to start moving. Due to the friction or direct connection between the conveying belt 4.1 and the ferrule tray 3, the movement of the belt will drive the ferrule tray 3 to move in a predetermined direction. In this way, the ferrule tray 3 and the ferrule positioning plate 5 and the ferrules on it can be accurately conveyed to the glue injection area and moved out after the glue injection is completed.

[0031] As an embodiment, the ferrule tray 3 is provided with positioning columns 3.1, and the ferrule positioning plate 5 is provided with positioning holes adapted to the positioning columns 3.1.

[0032] When it is necessary to install the ferrule positioning plate 5 on the ferrule tray 3, it is only necessary to align the positioning holes on the positioning plate with the positioning columns 3.1 on the tray, and then gently press or slide the positioning plate until the positioning columns are completely inserted into the positioning holes. This design ensures the stability and accuracy of the ferrule positioning plate 5 on the ferrule tray 3, preventing the positioning plate from shifting or shaking during movement or glue injection.

[0033] As an embodiment, the lateral movement assembly 8, the longitudinal movement assembly 9 and the lifting assembly 10 are all screw rod type movement assemblies.

[0034] A screw rod type movement assembly is usually composed of a screw rod, a nut, a driving motor and other components. The screw rod is a cylindrical body with a spiral groove, and the nut cooperates with the screw rod. When the screw rod rotates, the nut will move linearly along the spiral groove of the screw rod. This movement has the characteristics of high precision, high stability and easy control.

[0035] As an embodiment, the chassis 1 is also provided with a jacking cylinder 11 located in the glue injection area and distributed between the two support seats 2.

[0036] In the automatic glue injection device for optical fiber jumper ferrules, the piston rod of the jacking cylinder 11 can be connected to the ferrule tray 3 or some component below it. When glue injection operation is needed, the jacking cylinder 11 can be started to lift the ferrule tray 3 and the ferrule positioning plate 5 and the ferrules on it to a predetermined height by the extension of the piston rod, so that the glue injection head 7.1 can more easily and accurately contact the ferrules for glue injection.

[0037] The working principle of the utility model is as follows:

[0038] The device supports the entire system through the chassis 1, and the chassis is provided with two groups of opposite support seats 2 for stably mounting the ferrule tray 3. The ferrule tray 3 is provided with a ferrule positioning plate 5 having a plurality of fixing holes for preloading ferrules. The tray movement assembly 4 is connected to the ferrule tray 3 and is responsible for driving the tray to move on the chassis, thereby driving the ferrule positioning plate 5 and the ferrules thereon to enter and exit the glue injection area.

[0039] In the glue injection area, a moving frame 6 is arranged, and a glue injection seat 7 is arranged on the moving frame 6. The glue injection seat 7 is precisely positioned in a two-dimensional plane through a transverse moving assembly 8 and a longitudinal moving assembly 9. The glue injection seat 7 is provided with a glue injection head 7.1. It is noted that there is a conflict in the numbering of components, but according to the description in the original text, 8 here should refer to the glue injection head instead of the transverse moving assembly. In order to maintain consistency, 8 is still used to represent the glue injection head here. The glue injection head is moved in the vertical direction through a lifting assembly 10 to precisely control the glue injection height.

[0040] In operation, the tray moving assembly 4 sends the ferrule tray 3 provided with the ferrules into the glue injection area, and then the glue injection head 7.1 on the glue injection seat 7 moves above the ferrules to inject glue under the cooperation of the transverse moving assembly 8, the longitudinal moving assembly 9 and the lifting assembly 10. After the glue injection is completed, the tray moving assembly 4 moves the ferrule tray 3 out of the glue injection area for the next round of operation or subsequent processing.
