A centralized signal control solution is adopted, and the control points are integrated in the PLC control cabinet. Each motor control card needs to be connected to the PLC control cabinet separately, and all control points are introduced to the control cabinet through control cables; and each motor driver also needs to be powered separately, and the power supply of each motor driver also needs to be connected to the control cabinet separately, resulting in a large number of cable laying bases, complex on-site construction, and increased labor costs for control cabinet maintenance.

[0027] The power puncture needle 5 is used to puncture the power line to electrically connect with the power line, and the control puncture needle 6 is used to puncture the communication line to electrically connect with the communication line.

[0028] In this embodiment, one end of the drive housing 1 and one end of the cable housing 2 are connected via a connecting shaft 10 .

[0029] As an optional embodiment, the drive housing and the cable housing 2 are of an open-and-closed structure. Specifically, a connecting shaft is provided on the drive housing, a screw through hole 9 is provided on the cable housing 2, and the shaft hole is a vertical long hole 10. The connecting shaft on the drive housing 1 is movably arranged in the shaft hole of the cable housing 2.

[0030] It can be understood that as long as the opening and closing connection between the drive housing and the cable housing 2 can be achieved, the specific connection method is not limited.

[0031] In this embodiment, the drive housing 1 and the cable housing 2 are fixedly connected by fasteners, so that the power piercing needle 5 pierces the power line after aligning with the power line, and the control piercing needle 6 pierces the communication line after aligning with the communication line.

[0032] As an optional embodiment, the drive housing 1 is provided with a through hole 9 for passing a fastener, and the cable housing 2 is provided with a corresponding threaded hole 9 .

[0033] As an optional embodiment, the position where the fastener is fixed, that is, the position of the through hole can be set between the power puncture needle 5 and the control puncture needle 6.

[0034] It can be understood that the position where the fastener is fixed can also be set on one side or other position of the power puncture needle 5 or the control puncture needle 6, as long as the fastening connection between the drive housing 1 and the cable housing 2 and the puncture of the power line and the communication line can be achieved, without limitation.

[0035] As an optional implementation, the fastener fixing position can be set at one location, such as in the middle of the surface of the drive housing 1, or at two or more locations, such as at both ends of the surface of the drive housing 1, which is also not specifically limited.

[0036] As an optional implementation, the fasteners are bolts, and the fastening connection between the drive housing 1 and the cable housing 2 is achieved by bolt connection.

[0037] It is understandable that bolt connection is only one implementation method, and other connection methods may also be used, as long as the drive housing 1 and the cable housing 2 can be securely connected without limitation.

[0038] As an optional implementation, the through hole on the driving housing passes through the driving housing 1 , and the fastener passes through the driving housing 1 through the through hole and is fixed on the cable housing 2 .

[0045] The existing control card needs to use an additional sensor interface control when driving, and according to the centralized solution, it needs to be led out from the main control cabinet, and the number of cables laid is large. Therefore, the control device of this embodiment integrates driving and control as one, and integrates a signal input interface. The sensor signal input of each motor can be connected to the control device nearby, reducing the use of cables and on-site operation procedures.

[0049] Specific implementation methods include:

[0050] (1) Action command: The PLC sends a control command to the motor control device through the communication line, thereby driving the motor to perform the action;

[0051] (2) Feedback mechanism: The motor control device feeds back the input signals of peripheral devices and its own alarm information to the PLC through the communication line for real-time monitoring.

[0052] In this embodiment, a distributed control system is provided, in which multiple motor control devices are connected in sequence, and the power cord can pass through the power cord groove 7 of each motor control device in sequence, and the communication line passes through the second cord groove of each motor control device in sequence, so as to avoid that the wiring of all motor control devices is led out from the control cabinet, thereby realizing distributed control of the conveying system, reducing on-site control wiring and power supply wiring, and reducing the number of large signal control cabinets.

[0053] The above are only specific embodiments of the utility model, but the technical features of the utility model are not limited thereto. Any simple changes, equivalent replacements or modifications made based on the utility model to solve basically the same technical problems and achieve basically the same technical effects are all included in the protection scope of the utility model.
