Problems solved by technology

[0004] The servo control device of this kind of structure uses the heat dissipation aluminum plate to seal the control circuit board in the housing, which can seal and prevent the control circuit board from dust while enhancing the heat dissipation performance of the control circuit board; During installation, the servo motor needs to be fixedly connected to the machine head of the sewing machine first, and then the casing is connected. Since the control circuit board is located in the lower cavity of the casing, the motor socket on the circuit board is located on the side of the casing facing away from the operator. In the protruding part on the side, the installation direction of the motor socket on the control circuit board and the housing is opposite. Pull out the connecting wire of the motor through the through hole of the upper cavity of the housing, then extend the connecting wire of the motor from the bottom of the housing into the protruding part, and then insert the connecting wire of the motor into the motor in the protruding part In the plug interface, this structure makes it very troublesome to connect the motor and the circuit board, and the installation efficiency is low

Embodiment 1

[0030] Such as figure 1 , figure 2 , image 3 , Figure 6 As shown, the lockstitch sewing machine control device includes a housing 1 , a circuit board 2 and a heat dissipation aluminum plate 3 . The housing 1 is in the shape of a box, with a cavity 11 inside, the motor is located on the upper part of the cavity 11 of the housing 1 (marked in the figure), the circuit board 2 and the heat dissipation aluminum plate 3 are located at the lower part of the cavity 11 of the housing 1, and The circuit board 2 is fixedly connected with the housing 1 through the heat dissipation aluminum plate 3 and bolts, the heat dissipation aluminum plate 3 seals the circuit board 2, and the heat dissipation aluminum plate 3 plays the role of heat dissipation and dustproof for the circuit board 2.

[0031] Such as figure 1 , figure 2 , image 3 As shown, the connection structure includes a connection plate 4 , a connection port 5 and a protective cover 7 .

[0032] The connection plate 4 i...

Embodiment 2

[0036] Such as Figure 7 As shown, the structure and principle of this embodiment are basically the same as that of Embodiment 1, the difference is that in this embodiment, the connecting port 5 only runs through the connecting portion 42, that is, the connecting port 5 is located on the side of the connecting plate 4, the In this structure, the motor socket 6 can directly pass through the connection port 5, and the peripheral outer wall of the motor socket 6 is attached to the edge of the connection portion 42 at the edge of the connection port 5, that is, the motor socket 6 blocks the connection port 5, There is no need to provide the protective cover 7, and it also plays the role of dustproof and insulating, so that the whole connection structure is simple in structure and low in manufacturing cost. Of course, in actual production, a protective cover 7 matching the shape of the connection port 5 can also be provided in the connection port 5 .

Abstract

The invention provides a connecting structure for a motor and a circuit board in a flat sewing machine control device and belongs to the technical field of sewing machines. The connecting structure solves the problems of complicated connection between the motor and the circuit board, and the like at present. According to the connecting structure for the motor and the circuit board in the flat sewing machine control device, the control device comprises a housing internally provided with a cavity, the circuit board and a heat-dissipation aluminum plate, wherein the circuit board is fixed at the lower part of the cavity of the housing via the heat-dissipation aluminum plate. The connecting structure comprises a connecting plate at the top of the heat-dissipation aluminum plate, wherein a connector is arranged on the connecting plate, and a motor socket is arranged at the top of the circuit board and located in the connector. The connecting structure for the motor and the circuit board has the advantage of high mounting efficiency for connecting the motor and the circuit board.

Description

technical field [0001] The invention belongs to the technical field of sewing machines, relates to a lockstitch sewing machine, in particular to a connection structure between a motor and a circuit board in a control device of a locket sewing machine. Background technique [0002] The traditional sewing machine servo control system generally includes an operation box, a motor, a controller, etc. The traditional sewing machine operation box is installed on the casing, and the controller is suspended under the table. Considering the problem of heat dissipation, its volume is often large and takes up less space. larger. Because the controller is under the table, the controller is connected with the electrical actuators on the machine head and the operation box through many long cables and plugs. Therefore, the separation of the traditional sewing machine servo control device from the machine head affects the appearance of the whole machine, the performance is not stable enough...
