[0017] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0018] Reference below Figure 1 and Figure 2 A wire-reeling and -unreeling device according to an embodiment of the present invention is described.

[0019] like Figure 1 and Figure 2 As shown, the cable retracting and releasing device according to the embodiment of the present invention comprises a cable drum 1 and a terminal block 2 .

[0020] The cable drum 1 can rotate around the axial direction of the cable drum 1, and a first connector 11 is provided at one axial end of the cable drum 1. The wiring seat 2 is provided with a second connector 21, and the wiring seat 2 can move closer to and away from the cable drum 1 so that the first connector 11 and the second connector 21 can be connected and disconnected, and the first connector 11 and the second connector 21 can transmit electrical signals when connected.

[0021] Specifically, Figure 1 and Figure 2As shown, the cable drum 1 is horizontally arranged and can be driven to rotate in a vertical direction for winding and releasing the wound cable. A vertically arranged first connector 11 is provided on the top of the cable drum 1, and the first connector 11 is electrically connected to the wound cable. A wiring seat 2 is horizontally arranged and arranged above the cable drum 1, and the wiring seat 2 is used to connect external cables. A vertically arranged second connector 21 is provided at the bottom of the wiring seat 2, and the second connector 21 is electrically connected to the external cable. The second connector 21 is arranged opposite to the first connector 11 in the vertical direction, and the wiring seat 2 can be driven to move in the vertical direction and drive the second connector 21 to move in the vertical direction, so that the second connector 21 is connected to and detached from the first connector 11. When the first connector 11 and the second connector 21 are connected, electrical signals can be transmitted to electrically connect the wound cable and the external cable.

[0022] It can be understood that the terminal block is not limited to moving in the vertical direction relative to the cable reel. In other embodiments, a horizontally arranged first connector is provided on the top of the cable reel, and the terminal block is provided with a horizontally arranged second connector. The terminal block can move in the horizontal direction relative to the cable reel so that the first connector and the second connector can be connected and disconnected.

[0023] The cable drum of the wire-reeling device of the embodiment of the present invention is provided with a first connector, and the wiring seat is provided with a second connector. The second connector is connected and disconnected from the first connector by the movement control of the wiring seat. When the cable drum is wound and unwound, the first connector and the second connector are disconnected to avoid knotting of the external cable connected to the wiring seat. After the cable drum stops rotating, the first connector and the second connector are connected to make the wound cable connected to the cable drum electrically connected to the external cable, so that the wire-reeling device has a higher working efficiency. At the same time, because the space occupied by the wiring seat is smaller than the space required for manual operation, the wire-reeling device has a smaller occupied space, which is convenient for the installation of the wire-reeling device.

[0024] In some embodiments, the cable retracting and unreeling device of the embodiment of the present invention further includes a positioning assembly, which is disposed on the cable reel 1 and / or the terminal block 2 and is used to rotate the cable reel 1 to a position where the first connector 11 and the second connector 21 are relatively arranged.

[0025] Specifically, the positioning components can be entirely disposed on the cable reel 1, or entirely disposed on the terminal block 2, or partially disposed on the cable reel 1 and the other partially disposed on the terminal block 2, for positioning so that the cable reel 1 is rotated to a position where the first connector 11 and the second connector 21 are relatively arranged in the vertical direction.

[0026] Preferably, the positioning assembly includes an encoder, which is arranged on the cable drum 1.

[0027] It can be understood that, in other embodiments, the positioning component can also be a laser positioning component, which includes a laser transmitter and a laser receiver, one of which is arranged on the cable reel 1 and the other is arranged on the terminal block 2.

[0028] In some embodiments, the first connector 11 and the second connector 21 are arranged in a one-to-one correspondence, and the currents passing through the plurality of first connectors 11 are different, and the currents passing through the plurality of second connectors 21 are different.

[0029] like Figure 1 and Figure 2 As shown, there are three first connectors 11 and three second connectors 21 arranged in a one-to-one correspondence. The three first connectors 11 and the three second connectors 21 are arranged at intervals around the axis of the cable drum 1. Along the circumference of the cable drum 1, the current passing through the three first connectors 11 increases sequentially, and the current passing through the three second connectors 21 also increases sequentially, and they are arranged corresponding to the three first connectors 11.

[0030] The three first connectors 11 may all be connectors, or may all be interfaces, or may have some as connectors and the other as interfaces. The second connector 21 arranged opposite to the connector of the first connector 11 is an interface, and the second connector 21 arranged opposite to the interface of the first connector 11 is a connector.

[0031] Preferably, two of the first connectors 11 use PIN pins, more preferably pogo pins, and the two groups of PIN pins have different cross-sections or different needle lengths to have different through-currents, and the remaining first connector 11 uses a plug-in terminal to have the maximum through-current, and the outer periphery of the plug-in terminal has an insulating shell. The second connector 21 arranged opposite to the PIN pin is a PIN interface, which is adapted to the corresponding PIN pin, and the second connector 21 arranged opposite to the plug-in terminal is a plug-in port, which is adapted to the corresponding plug-in terminal.

[0032] In some embodiments, the cable drum 1 includes a first wire blocking plate 12 , a second wire blocking plate 13 and a wire winding shell 14 .

[0033] The first connector 11 is arranged on the first wire block plate 12 along the axial direction of the cable drum 1. One end of the first connector 11 is used to connect the second connector 21, and the other end of the first connector 11 is used to connect the winding cable. The second wire block plate 13 and the first wire block plate 12 are arranged at intervals along the axial direction of the cable drum 1. The winding shell 14 is arranged around the axial direction of the cable drum 1 and is arranged between the first wire block plate 12 and the second wire block plate 13. The winding shell 14 is provided with a through hole 141 for the winding cable to pass through, and the other end of the first connector 11 is located inside the winding shell 14.

[0034] like Figure 2As shown, the first wire baffle plate 12 and the second wire baffle plate 13 are both horizontally arranged circular plates, the first wire baffle plate 12 and the second wire baffle plate 13 are arranged at intervals in the vertical direction, and the first wire baffle plate 12 and the second wire baffle plate 13 are coaxially arranged, and the first wire baffle plate 12 is located between the second wire baffle plate 13 and the terminal block 2.

[0035] The wire winding shell 14 is an annular shell wound in the vertical direction. The wire winding shell 14 is connected between the first wire baffle plate 12 and the second wire baffle plate 13, and is coaxially arranged with the first wire baffle plate 12 and the second wire baffle plate 13. The winding cable is used to be wound on the wire winding shell 14 and is located between the first wire baffle plate 12 and the second wire baffle plate 13. The wire winding shell 14 is provided with a through hole 141, and the end of the winding cable extends into the wire winding shell 14 through the through hole 141.

[0036] The first connector 11 is vertically inserted into the first wire blocking plate 12 . The upper end of the first connector 11 is used to connect to the second connector 21 . The lower end of the first connector 11 is located in the wire winding housing 14 and is used to connect to the end of the wound cable in the wire winding housing 14 .

[0037] The wound cable is connected to the first connector 11 in the winding shell 14, and then extends out of the winding shell 14 through the through hole 141. As the cable drum 1 rotates, it is wound and released on the outer peripheral surface of the winding shell 14, and the wound cable is bent at the through hole 141. Therefore, the through hole 141 has a clamping effect on the wound cable, which can prevent the wound cable from detaching from the first connector 11 during the winding and releasing process. At the same time, the winding shell 14 also protects the end of the wound cable and the first connector 11, preventing the wound wound cable from touching the end of the wound cable, causing the wound cable and the first connector 11 to detach.

[0038] Preferably, the first wire baffle plate 12 includes a center plate 121 and a baffle 122, the baffle 122 is annular in the vertical direction, and the center plate 121 is circular in the vertical direction. The center plate 121 is detachably arranged on the baffle 122 and is located at the center of the baffle 122. The first connector 11 is passed through the center plate 121 in the vertical direction. The center plate 121 and the space surrounded by the wire winding shell 14 are arranged opposite to each other in the vertical direction and are located above the space surrounded by the wire winding shell 14. The space surrounded by the wire winding shell 14 can be opened and closed by disassembling and assembling the center plate 121, so as to connect the end of the wound cable to the first connector 11 and perform maintenance.

[0039] In some embodiments, the wire reeling and unwinding device of the embodiment of the present invention also includes a transmission gear and a first driving member, the outer peripheral end of the second wire baffle plate 13 has a gear portion 131, and / or the end of the second wire baffle plate 13 away from the first wire baffle plate 12 has a gear portion 131, the gear portion 131 is arranged around the axial direction of the cable drum 1, the transmission gear is meshed and connected with the gear portion 131, and the first driving member is connected to the transmission gear to drive the transmission gear to rotate around the axial direction of the transmission gear.

[0040] like Figure 2 As shown, the outer peripheral end of the second wire baffle plate 13 has a protrusion and a gear portion 131, and the protrusion and the gear portion 131 both extend along the circumference of the second wire baffle plate 13. The protrusion and the gear portion 131 are arranged in sequence along the vertical direction, and the protrusion is located at the upper end of the gear portion 131. The transmission gear is meshed and connected with the gear portion 131, and the first driving member is connected to the transmission gear. Preferably, the first driving member is a rotating motor, and the first driving member and the transmission gear are arranged on the base, and the second wire baffle plate 13 is also arranged on the base through a bearing.

[0041] The first driving member drives the transmission gear to rotate around the axis of the transmission gear, and the transmission gear drives the second wire baffle plate 13 to rotate around the axis of the second wire baffle plate 13 through the gear portion 131, so as to drive the cable drum 1 to rotate around the axis of the cable drum 1, thereby driving the cable drum 1 to wind and release the wound cable through the forward and reverse rotation of the first driving member. And the gear ratio between the transmission gear and the gear portion 131 can play a deceleration role, so as to prevent the cable drum 1 from rotating too fast under the drive of the first driving member, thereby affecting the winding and releasing effect of the wound cable. At the same time, the protrusion plays a protective role, so as to prevent the wound cable from being squeezed and damaged by the meshing transmission gear and the gear portion 131.

[0042] It can be understood that the gear portion is not limited to being disposed at the outer peripheral end of the second wire blocking plate. In other embodiments, the gear portion is disposed at the bottom of the second wire blocking plate.

[0043] It can be understood that the cable drum is not limited to being driven by gears. In other embodiments, the cable drum is provided with a rotating shaft, and the first driving member is connected to the rotating shaft.

[0044] In some embodiments, the wire retracting and releasing device of the embodiment of the present invention also includes a second driving member 3, the terminal block 2 includes a terminal disk 22 and a bracket 23, the terminal disk 22 is arranged at one end of the bracket 23, and the other end of the bracket 23 is connected to the second driving member 3, the second driving member 3 and the cable drum 1 are arranged at intervals along the radial direction of the cable drum 1, the second driving member 3 is used to drive the terminal disk 22 and the bracket 23 to move axially along the cable drum 1, the second connector 21 is passed through the terminal disk 22, one end of the second connector 21 is used to connect to the first connector 11, and the other end of the second connector 21 is used to connect to an external cable.

[0045] like Figure 1As shown, the terminal block 2 includes a terminal disk 22 and a bracket 23, the bracket 23 extends in the left-right direction, the right end of the bracket 23 is located above the cable drum 1, and is provided with a terminal disk 22, the terminal disk 22 is located above the center plate 121, and the second connector 21 is vertically penetrated on the terminal disk 22, the lower end of the second connector 21 is used to connect to the first connector 11, and the upper end of the second connector 21 is used to connect to external cables.

[0046] The left end of the bracket 23 extends to the left side of the cable drum 1 and is connected to the vertically arranged second drive member 3. The second drive member 3 and the cable drum 1 are arranged at intervals in the left and right directions. The second drive member 3 is preferably a screw motor to drive the bracket 23 and the wiring tray 22 to move in the vertical direction, so that the second connector 21 is connected to and disconnected from the first connector 11.

[0047] The terminal block 2 can ensure stable connection and disconnection between the first connector 11 and the second connector 21, while avoiding interference between the second drive member 3 and the cable drum 1, and making the retractable device have a compact structure and a small occupied space, which is convenient for the installation of the retractable device.

[0048] In some embodiments, the wire retracting and unreeling device of the embodiment of the present invention further includes a guide member 4 , which is connected to the bracket 23 to guide the bracket 23 to move along the axial direction of the cable drum 1 .

[0049] like Figure 1 The guide member 4 preferably includes a slider and a slide groove connected in a vertical direction, the slider and the slide groove are both strips extending in the vertical direction, the slide groove is arranged on the base, the slider is arranged on the rear end face of the bracket 23, and the front end face of the bracket 23 is provided with a wiring plate 22 and a second driving member 3. The guide member 4 can guide the bracket 23 and the wiring plate 22 to move in the vertical direction to ensure the accurate connection between the first connector 11 and the second connector 21.

[0050] The sliders and the slide grooves are connected to each other in a corresponding manner, and the sliders are arranged at intervals along the left and right directions on the bracket 23 to ensure the stability of the bracket 23 and the wiring tray 22 moving in the vertical direction, and to prevent the bracket 23 and the wiring tray 22 from tilting, thereby ensuring the precise connection between the first connector 11 and the second connector 21.

[0051] It is understandable that in other embodiments, the guide member may also be a linear guide rail or a guide rod inserted into the bracket.

[0052] In some embodiments, the wire retracting and unwinding device of the embodiment of the present invention further includes a wire reeling assembly 5 , and the wire reeling assembly 5 and the cable drum 1 are arranged at intervals along the radial direction of the cable drum 1 .

[0053] like Figure 1As shown, the left side of the cable drum 1 is provided with spaced-apart wire-winding assemblies 5, which are arranged on a base. The wound cables wound and released by the cable drum 1 are all wound through the wire-winding assemblies 5 to avoid the wound cables from rotating and tangling, thereby ensuring the winding and releasing effects of the wound cables.

[0054] In some embodiments, the wire winding assembly 5 includes at least two rollers 51 and a third driving member, wherein the axes of the two rollers 51 are arranged in parallel, and the two rollers 51 are arranged at intervals along the radial direction of the rollers 51, and the spacing space between the two rollers 51 is used for winding cables to pass through, and the wound cables abut between the two rollers 51, and the third driving member is used to drive the two rollers 51 to rotate in opposite directions.

[0055] like Figure 1 As shown, the wire-winding assembly 5 includes two rollers 51 extending in the vertical direction. The rollers 51 are provided on a base and can rotate in the vertical direction relative to the base. The two rollers 51 are arranged at intervals in the front-to-back direction. The shortest distance between the two rollers 51 in the front-to-back direction is consistent with the diameter of the wound cable. The wound cable passes between the two rollers 51 and abuts against the outer circumferential surfaces of the two rollers 51. The two rollers 51 rotate in opposite directions, and the same roller 51 rotates in opposite directions when releasing the wound cable and winding the wound cable, so as to cooperate with the winding and releasing of the cable drum 1, and the wound cable is winded by the rotation of the two rollers 51.

[0056] The third driving member may be two members corresponding to the two rollers 51 one by one, or may be drivingly connected to the two rollers 51 . The third driving member is used to drive the two rollers 51 to rotate in opposite directions. Preferably, the third driving member is a rotating motor.

[0057] The third driving member can only drive the two rollers 51 to rotate in one direction. Specifically, the third driving member is preferably connected to the two rollers 51 through a one-way bearing. The third driving member can drive the two rollers 51 to rotate only when releasing the wound cable, so as to provide power for releasing the wound cable through the two rollers 51. In other words, the two rollers 51 pull the wound cable released by the cable drum 1 to the left to avoid the accumulation of the wound cable between the two rollers 51 and the cable drum 1. When winding the wound cable, the third driving member stops, the cable drum 1 drives the wound cable to move, and the two rollers 51 rotate under the friction of the wound cable to pull the cable.

[0058] The third driving member can also drive the two rollers 51 to rotate forward and reversely. Specifically, when releasing the winding cable, the third driving member drives one roller 51 to rotate forward and drives the other roller 51 to rotate reversely to pull the winding cable released by the cable drum 1 to the left. When winding the winding cable, the third driving member drives one roller 51 to rotate reversely and drives the other roller 51 to rotate forward to assist in retrieving the winding cable and push the winding cable toward the cable drum 1. At this time, the linear speed of the third driving member driving the roller 51 needs to be consistent with the linear speed of the cable drum 1 winding the winding cable.

[0059] The wire retracting and releasing device of the embodiment of the present invention is preferably used on electrical equipment that needs to wind and release cables, such as a welding machine, and can reduce the size of the electrical equipment and improve the working efficiency of the electrical equipment.
