Description

Technical Field

[0001] The utility model relates to the technical field of embroidery machines, in particular to an embroidery frame sensing mechanism of an embroidery machine. Background Art

[0002] Embroidery machines usually need to use a sensing mechanism to sense the position of the embroidery frame, so as to locate the embroidery frame and determine the distance the embroidery frame needs to move. The existing sensing mechanism is generally an optocoupler sensor, that is, an optocoupler baffle is installed on the embroidery frame, and a corresponding optocoupler is installed on the driving mechanism. When the embroidery frame moves, the optocoupler baffle will block the optocoupler, which is used as a sensing signal to determine the position of the embroidery frame. The existing optocoupler is installed on the driving mechanism through an optocoupler bracket, and an assembly position needs to be reserved for the optocoupler bracket, which not only takes up space, but is also prone to collision with the embroidery frame when it moves, damaging the machine. In addition, the optocoupler baffle on the embroidery frame is also prone to loosening under high-speed movement, resulting in problems such as inaccurate sensing position. Utility Model Content

[0016] The present invention is further described below in conjunction with specific embodiments.

[0017] refer to Figure 1 , 2 , 3, 4, an embroidery frame sensing mechanism of an embroidery machine, comprising a movable plate 1 for driving an embroidery frame 7 to move, an L-shaped mounting plate 2 for the movable plate to slide and equipped with a driving mechanism, the L-shaped mounting plate 2 is embedded with a sensing proximity device 5 that can sense the movable plate 1 when it approaches a sensing distance, and the vertical distance between the movable plate 1 and the sensing proximity device 5 is 0mm-1.5mm.

[0018] Furthermore, when the movable plate 1 and the inductive proximity sensor 5 reach the sensing distance, the inductive proximity sensor 5 transmits information to the driving mechanism, and the driving mechanism drives the movable plate 1 to move. The sensing distance is the vertical distance between the movable plate 1 and the inductive proximity sensor 5. Preferably, the vertical distance between the movable plate 1 and the inductive proximity sensor 5 is 0.5-1.5 mm. The inductive proximity sensor 5 is used to replace the existing optical coupler induction. It is only necessary to set the sensor on the L-shaped mounting plate 2 and let the movable plate 1 be the induction body. There is no need to install a sensor sheet, which reduces the installation cost and is not easy to be damaged.

[0019] Furthermore, the L-shaped mounting plate 2 includes a bottom plate 3 for mounting the movable plate 1 and a driving plate 4 for mounting the driving mechanism.

[0020] Furthermore, the driving plate 4 is provided with a mounting groove 6 for mounting the inductive proximity sensor 5. The inductive proximity sensor 5 is directly embedded in the mounting groove 6, and no additional mounting bracket is required to mount the inductive proximity sensor 5, which saves space and makes the structure more compact.

[0021] Furthermore, a sensor base 9 for mounting the inductive proximity sensor 5 is provided at a position corresponding to the mounting groove 6. The sensor base 9 is used to mount the inductive proximity sensor 5, and the sensor base 9 is bolted to the inductive proximity sensor 5 to fix the inductive proximity sensor 5 in the mounting groove.

[0022] Furthermore, the movement of the embroidery frame 7 along the X-axis or Y-axis can be equipped with an inductive proximity device 5 and a proximity-sensitive movable plate 1. The inductive proximity device 5 is adapted to drive the embroidery frame in the X-axis direction or the Y-axis direction.

[0023] Furthermore, the driving plate 4 is provided with a driving motor 8 which can receive information about the proximity sensor 5 approaching the movable plate 1 and control the movement of the movable plate 1. After the proximity sensor 5 senses the position of the movable plate 1, it transmits the information to the driving motor 8, and then the driving motor 8 drives the movable plate 1 to move.

[0024] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
