Description

Technical Field

[0001] This utility model relates to the field of automated insertion equipment, and in particular to a two-axis working head mechanism for an insertion machine. Background Technology

[0002] Currently, many companies in the PCB component manufacturing industry have adopted component insertion machines to achieve automated production. Machine component insertion can improve production cycle time, reduce production costs, and at the same time ensure product quality requirements. There is still a very large market demand both domestically and internationally. Component insertion machines will also have different focuses depending on the needs of different customers.

[0003] In existing industrial insertion machines, after the working head completes material gripping, visual inspection of the material pins is required to ensure accuracy. Traditional solutions typically mount the light source on a fixed camera at the same height as the track. In this case, taking a picture requires the working head to move above the fixed camera and then separately lower the pins to the position illuminated by the light source. This solution involves redundant movement paths and extends the cycle time of each operation. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of redundant working head movement paths in existing technologies by proposing a two-axis working head mechanism for a plug-in machine.

[0005] To address the problems existing in the prior art, the present invention adopts the following technical solution:

[0006] A two-axis working head mechanism for a plug-in machine includes a working head frame. Two hollow splined shafts are symmetrically arranged on the working head frame. A gripper cylinder is fixedly mounted on the lower end of each of the two hollow splined shafts. A ring-shaped flylight is fixedly mounted below the working head frame. The two gripper cylinders are located inside the ring structure of the flylight. The light source projection direction of the flylight is coaxial with the material gripping end of the gripper cylinder.

[0007] Preferably, a drive assembly is provided above the working head frame. The drive assembly consists of two drive motors, two lead screws, and two lifting plates. The output end of the drive motor is connected to the end of the lead screw, one end of the lifting plate is threadedly connected to the lead screw, and the other end of the lifting plate is rotatably connected to the hollow spline shaft.

[0008] Preferably, two slide rails are fixedly provided on one side below the working head frame, and a slider is slidably provided on the slide rails. The slider is rotatably connected to the hollow spline shaft.

[0009] Preferably, a shaft motor is fixedly installed on the side of the working head frame away from the hollow spline shaft, and a synchronous pulley and two spline nuts are rotatably provided in the middle of the working head frame. The synchronous pulley and the spline nuts form a right-angled triangle. A belt is sleeved between the synchronous pulley and the spline nuts, and the hollow spline shaft is in contact with the inner wall of the center of the spline nuts.

[0010] Preferably, a camera is fixedly mounted on the side of the working head frame away from the hollow spline shaft, and a ring-shaped searchlight is fixedly mounted on the lower end of the working head frame, with the camera output end facing the center of the searchlight.

[0011] Preferably, the upper end of the hollow spline shaft is rotatably provided with an air pipe connector.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. In this utility model, by directly integrating the ring-shaped flying light under the working head frame and making it form a coaxial supplementary lighting structure around the gripper cylinder, the working head does not need to move to an independent light source position after grabbing the material. The flying light moves synchronously with the working head and can directly provide stable and uniform ring lighting for the needle area during the movement. Moreover, it eliminates the redundant movement of the working head's back-and-forth positioning and shortens the time consumption of the inspection process.

[0014] 2. In this utility model, by setting two hollow splined shafts that can be operated independently, the two hollow splined shafts operate synchronously to pick up materials, thereby improving processing efficiency. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] In the description of this specification, the references to terms such as "embodiment," "one embodiment," "some implementations," "exemplary," and "one implementation," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or implementation is included in at least one embodiment or implementation of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or implementation. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or implementations.

[0024] Example: This example provides a two-axis working head mechanism for a plug-in machine. See [link / reference]. Figure 1-4Specifically, the device includes a working head frame 1, on which two hollow splined shafts 11 are symmetrically arranged. A gripper cylinder 12 is fixedly mounted at the lower end of each of the two hollow splined shafts 11. A ring-shaped fly-shooting light 13 is fixedly mounted below the working head frame 1. The two gripper cylinders 12 are located inside the ring-shaped structure of the fly-shooting light 13. The light source projection direction of the fly-shooting light 13 is coaxial with the material gripping end of the gripper cylinder 12. The two hollow splined shafts 11 move up and down independently. When the two hollow splined shafts 11 drive the gripper cylinder 12 to pick up material, they operate synchronously. When inserting material, they proceed sequentially. The gripper cylinder 12 is controlled by airflow to grip the material. When the hollow splined shaft 11 drives the gripper cylinder 12 to pick up the material and moves to the inside of the fly-shooting light 13, the light source can just illuminate the needle of the material. The working head only needs to move above the fixed camera to take a picture, thus achieving fly-shooting. This eliminates the redundant action of the working head reciprocating for positioning, shortening the time consumed in the inspection process.

[0025] In the specific implementation process, such as Figure 2 and Figure 4 As shown, a drive assembly 2 is provided above the working head frame 1. The drive assembly 2 consists of two drive motors 21, two lead screws 22, and two lifting plates 23. The output end of the drive motor 21 is connected to the end of the lead screw 22. One end of the lifting plate 23 is threadedly connected to the lead screw 22, and the other end of the lifting plate 23 is rotatably connected to the hollow spline shaft 11. The drive motor 21 drives the lead screw 22 to rotate, and the lead screw 22 drives the lifting plate 23 to move up and down. The lifting plate 23 drives the hollow spline shaft 11 to move synchronously, so that the hollow spline shaft 11 drives the gripper cylinder 12 to pick up and insert materials.

[0026] In the specific implementation process, such as Figure 3 and Figure 4 As shown, two slide rails 3 are fixedly installed on one side below the working head frame 1. A slider 31 is slidably mounted on the slide rails 3. The slider 31 is rotatably connected to the hollow spline shaft 11. The stability of the hollow spline shaft 11 during movement is improved by the slider 31 and the slide rails 3. The hollow spline shaft 11, the slider 31 and the lifting plate 23 move up and down synchronously. However, the hollow spline shaft 11 can rotate along the slider 31 and the lifting plate 23 to adjust the angle of the gripper cylinder 12, so as to facilitate the insertion of the needle of the material into the horizontal or vertical groove of the workpiece.

[0027] In the specific implementation process, such as Figure 3 and Figure 4As shown, a shaft motor 4 is fixedly installed on the side of the working head frame 1 away from the hollow spline shaft 11. A synchronous pulley 41 and two spline nuts 42 are rotatably installed in the middle of the working head frame 1. The synchronous pulley 41 and the spline nuts 42 form a right triangle. A belt 43 is sleeved between the synchronous pulley 41 and the spline nuts 42. The hollow spline shaft 11 is in contact with the inner wall of the center of the spline nuts 42. The shaft motor 4 drives the synchronous pulley 41 to rotate. The synchronous pulley 41 drives the spline nuts 42 to rotate through the belt 43. Since the spline nuts 42 are in contact with the outer wall of the hollow spline shaft 11, the hollow spline shaft 11 can not only move up and down between the spline nuts 42, but also drive the hollow spline shaft 11 to rotate synchronously when the spline nuts 42 rotate, which is used to adjust the angle of the gripper cylinder 12.

[0028] In the specific implementation process, such as Figure 2 and Figure 3 As shown, a camera 5 is fixedly mounted on the side of the working head frame 1 away from the hollow spline shaft 11. A circular searchlight 51 is fixedly mounted on the lower end of the working head frame 1. The output end of the camera 5 is directly facing the center of the searchlight 51. The camera 5 is mounted on the back of the working head frame 1 and is used to capture the MACK point so that the working head can accurately position the workpiece. The searchlight 51 provides a light source for the camera 5.

[0029] In the specific implementation process, such as Figure 2 and Figure 4 As shown, the upper end of the hollow spline shaft 11 is rotatably equipped with an air pipe connector 6. The air pipe connector 6 is used to connect an external air pump. The airflow passes through the interior of the hollow spline shaft 11 to control the operation of the gripper cylinder 12. The air pipe connector 6 is a rotary connector that is rotatably connected to the top end of the hollow spline shaft 11. The bottom end of the hollow spline shaft 11 is fixedly connected to the air inlet of the gripper cylinder 12.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
