Description

Technical Field

[0001] This invention relates to the field of industrial robot technology, and in particular to a power cord anti-pull mechanism and an industrial six-axis robot. Background Technology

[0002] Equipment that requires electrical power for operation is widely used across various industries. When these devices are powered on, the power cord sometimes comes loose from the power socket due to the pulling effect caused by the rotation of the equipment.

[0003] In particular, with the development of technology, the application fields of robots are becoming increasingly broad. Currently, robots are widely used in technical fields such as material handling and welding. Furthermore, the widespread application of robots has significantly reduced the labor intensity of workers and improved production efficiency and product manufacturing quality. Six-axis robots are now the most widely used type on the market. To maintain the normal operation of a six-axis robot, a power cord needs to be plugged into a power outlet.

[0004] When powering a six-axis robot, the power cord is usually plugged directly into the power socket. However, in actual use, the connection between the power cord and the power supply box is easily pulled. Repeated pulling over a long period can cause poor contact between the power cord and the power supply box, resulting in sudden power outages and the robot being unable to work normally.

[0005] Based on the above situation, there is an urgent need for a device that can prevent the power cord and power supply box from being pulled when a six-axis robot is working. Summary of the Invention

[0006] To address the aforementioned technical problems, this invention provides a power cord anti-pull mechanism and an industrial six-axis robot, which can prevent problems such as poor contact or disconnection between the power cord and the power supply box during the operation of the six-axis robot.

[0007] In a first aspect, embodiments of the present invention disclose a power cord anti-pull mechanism, applied to equipment requiring power for operation, comprising: a power cord, a power supply box, and an anti-pull device.

The outer side of the second threaded rod is threaded, and the second threaded sleeve is threadedly connected to the second threaded rod. The first threaded rod and the second threaded rod rotate in opposite directions. The first clamping arm is connected to the first threaded sleeve via the first connecting rod, and the second clamping arm is connected to the second threaded sleeve via the second connecting rod, so that the dual-axis motor drives the first clamping arm and the second clamping arm to move relative to each other.

[0011] Furthermore, the power unit also includes: a first bearing and a second bearing, wherein the first threaded rod is rotatably connected to one side of the inner wall of the power unit housing via the first bearing; and the second threaded rod is rotatably connected to the other side of the inner wall of the power unit housing via the second bearing.

[0012] Furthermore, an adjustment port is provided on one side of the power unit housing. The power unit also includes: a door, which is rotatably disposed on one side of the adjustment port, so as to close the adjustment port and thus the power unit housing by rotation; and a handle, which is installed on the door, so as to open or close the door by pushing or pulling the handle. (First clamping arm, second clamping arm, first clamping arm, second clamping arm, first clamping arm, second clamping arm)

[0013] Furthermore, the power cord anti-pull mechanism also includes a spring-back device, which is disposed on both sides of the power socket and is used to pop out the power cord when the power cord is released from its limit.

[0015] Furthermore, the rebound device also includes: two slide grooves and two sliders, the two slide grooves being respectively opened on opposite sides of the inner sidewall of the rebound housing; the two sliders being respectively installed at the two ends of the horizontal plate and slidably disposed in the corresponding two slide grooves to slide along the two slide grooves.

[0016] Secondly, embodiments of the present invention also disclose an industrial six-axis robot, including: the aforementioned power cord anti-pull mechanism.

[0017] Furthermore, the power cord anti-pull mechanism is an automatic control device.

[0018] By adopting the above technical solution, the present invention has at least the following beneficial effects:

[0019] The power cord anti-pull mechanism provided by the present invention secures the power plug at the end of the power cord to the power socket of the power box by setting an anti-pull device, thereby preventing problems such as poor contact and sudden power outage caused by pulling.

[0020] The anti-pull device includes a fastening device and a power device. The fastening device includes a first clamping arm and a second clamping arm. The power device includes a drive component, a first transmission assembly, and a second transmission assembly. The drive component can be a dual-axis motor. The first transmission assembly includes a first threaded rod, a first threaded sleeve, and a first connecting rod. The second transmission assembly includes a second threaded rod, a second threaded sleeve, and a second connecting rod. The first and second threaded rods are respectively connected to the two output shafts of the dual-axis motor. The first and second threaded sleeves are threadedly connected to the first and second threaded rods, respectively. One end of the first connecting rod is connected to the first clamping arm, and the other end is connected to the first threaded sleeve. One end of the second connecting rod is connected to the second clamping arm, and the other end is connected to the second threaded sleeve. The first and second clamping arms are located on opposite sides of the power plug. The threads of the first and second threaded rods have opposite directions, so that under the drive of the dual-axis motor, the first and second clamping arms can move relative to each other to clamp the power plug.

[0021] The first and second threaded rods are connected to the inner wall of the power unit housing via bearings, which can reduce wear during the rotation of the threaded rods.

[0022] The power cord anti-pull mechanism also includes a spring-loaded device. This device comprises a spring-loaded housing, within which a damper, a connecting block, and a connecting plate are arranged sequentially from left to right in the second inner cavity of the housing. A spring is located on the outside of the damper. When the power plug is inserted into the power socket, the power plug's support plate pushes the connecting plate, connecting block, and damper to move from right to left, compressing the spring and storing elastic potential energy. When the power plug is released from its limit, the spring releases the elastic potential energy, causing the damper, connecting block, and connecting plate to move from left to right, thus ejecting the power plug. This eliminates the need for manual unplugging of the power plug, preventing injury to workers due to potential electrical leakage or other safety hazards.

[0023] The rebound housing of the rebound device has a groove on each of the opposite sides of the side wall separated by the second inner cavity. Two slide rails are respectively installed at the two ends of the horizontal plate and are slidably disposed in the corresponding groove so as to slide along the groove, thereby reducing the shaking during the movement of the horizontal plate.

[0024] The power unit also includes a door and a handle to facilitate cleaning of the first inner cavity of the power unit. Attached Figure Description

[0034] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below with reference to specific examples and the accompanying drawings.

[0035] It should be noted that all uses of "first" and "second" in the embodiments of the present invention are for the purpose of distinguishing two entities or parameters with the same name but different names. It is clear that "first" and "second" are only for the convenience of expression and should not be construed as limiting the embodiments of the present invention. Subsequent embodiments will not explain this in detail.

[0036] This invention provides a power cord anti-pull mechanism and an industrial six-axis robot incorporating the power cord anti-pull mechanism. The invention limits the power cord by using an anti-pull device, preventing the power cord from detaching from the power socket in the event of a pull, thus achieving the purpose of preventing pull. This prevents poor contact between the power socket and the power cord, avoids sudden power outages, and allows the operating equipment to continue to work normally, thereby solving the problems mentioned in the background art.

[0037] Specifically, such as Figures 1-3 As shown, an embodiment of the present invention discloses a power cord anti-pull mechanism, which is applied to equipment that requires power to operate. The power cord anti-pull mechanism includes a power cord 1, a power box 2, and an anti-pull device 3. One end of the power cord 1 is provided with a power plug 11. A power socket 21 is provided on one side of the power box 2. The power plug 11 can be inserted into the power socket 21 to connect to the power supply. The anti-pull device 3 is disposed on the power box 2 and includes a fastening device 31 and a power device 32. The fastening device 31 is used to fasten the power plug 11 after it is inserted into the power socket 21, preventing pulling between the power cord 1 and the power socket 21; the power device 32 is used to provide power to the fastening device 31 to fasten the power plug 21.

[0038] Specifically, this power cord anti-pull mechanism is applied to equipment that requires power to operate. One end of the power cord 1 can be its own power plug 11, while the other end is located on the equipment requiring power and moves with it. A power socket 21 is located on one side of the power supply box 2, such as the front side. When the power plug 11 is inserted into the power socket 21, the equipment requiring power is connected to the power supply box 2. The anti-pull device 3 is located next to the power socket 21 in the power supply box 2 and mainly consists of two components: a fastening device 31 and a power unit 32. The power unit 32 clamps the power plug 11 into the power socket 21 using the fastening device 31 after the power plug 11 is inserted. This prevents the power cord 1 from being pulled during equipment operation, maintains a stable connection, avoids poor contact between the power plug 11 and the power socket 21, and prevents sudden power outages.

[0039] like Figure 1 As shown, in a preferred embodiment of the present invention, the fastening device 31 includes a first clamping arm 311 and a second clamping arm 312; the power device 32 includes a drive member, a first transmission assembly, and a second transmission assembly; the drive member has two power output ends with opposite rotation directions, one of which is connected to one end of the first transmission assembly, the other end of the first transmission assembly is connected to the first clamping arm 311, and the other power output end is connected to one end of the second transmission assembly, the other end of the second transmission assembly is connected to the second clamping arm 312; under the power action of the drive member, the first clamping arm 311 and the second clamping arm 312 can move towards each other to clamp the power plug 11, or move away from each other to release the power plug 11.

[0040] Specifically, the driving component can be any device capable of providing power to the fastening device 31, such as a dual-axis motor. More preferably, the power device 32 also includes a power device housing, which is a hollow box structure, preferably in a cuboid or cubic shape. The interior of the power device housing can house power components, such as the driving component, and linkage components, such as a first transmission assembly and a second transmission assembly. During operation, the driving component drives the first and second transmission assemblies to rotate, thereby causing the fastening device 31 to reciprocate. The fastening device 31 is located next to the power socket 21, which facilitates clamping the power plug 11 under the action of the driving force. As another optional embodiment, the power device 32 may only include a device that outputs power, such as a motor, to be directly connected to the connecting rod 33 via an output shaft.

[0041] like Figure 1 and Figure 3 As shown, in a preferred embodiment of the present invention, the power unit 32 includes a power unit housing 321. The power unit housing 321 is disposed on one side of the power socket 11, and a first inner cavity 3211 is formed therein. The driving component is a dual-axis motor 322, which is disposed within the first inner cavity 3211. The first transmission assembly includes a first threaded rod 323, a first threaded sleeve 324, and a first connecting rod 331. One end of the first threaded rod 323 is connected to one output end of the dual-axis motor 322, and the other end is rotatably connected to one side of the inner wall of the power unit housing 321. The outer side of the first threaded rod 323 is threaded, and the first threaded sleeve 324 is threadedly connected to the first threaded rod 323. The second transmission assembly includes a second threaded rod 325, a second threaded sleeve 326, and a second connecting rod. One end of the second threaded rod 325 is connected to the other output end of the dual-axis motor 322, and the other end is rotatably connected to the other side of the inner wall of the power unit housing 321. The outer side of the second threaded rod 325 is threaded, and the second threaded sleeve 326 is threadedly connected to the second threaded rod 325. The threads of the first threaded rod 323 and the second threaded rod 325 rotate in opposite directions. The first clamping arm 311 is connected to the first threaded sleeve 324 via the first connecting rod 331, and the second clamping arm 312 is connected to the second threaded sleeve 326 via the second connecting rod, so that the dual-axis motor 322 drives the first clamping arm 311 and the second clamping arm 312 to move relative to each other.

[0042] Specifically, the power unit housing 321 can be a rectangular hollow shell to provide working space for the dual-axis motor 322. It is known that the dual-axis motor 322 has an output end on each side. Each output end is connected to a threaded rod; for example, the first threaded rod 323 and the second threaded rod 325 are respectively connected to one output end. Furthermore, the threads of the first threaded rod 323 and the second threaded rod 325 rotate in opposite directions. In this case, when the dual-axis motor 322 is working, the first threaded sleeve 324 and the second threaded rod 325 can move relative to each other, i.e., they can move closer or further apart, thereby causing the first clamping arm 311 and the second clamping arm 3121 to clamp or release the power plug 11.

[0043] In this way, the threaded rod is rotated by a dual-axis motor, which in turn moves the threaded sleeve to one end. The threaded sleeve then moves the connecting rod and clamping arm to one end, causing one end of the clamping arm to come into contact with both ends of the power cord, thus limiting the power cord. In the event of pulling, the power cord and the power socket will not detach, thereby achieving the purpose of preventing pulling. This prevents poor contact between the power socket and the power cord, avoids sudden power outages, and allows the equipment to continue to operate normally.

[0044] Specifically, the dual-axis motor 322 can also be replaced by two motors plus a controller. One motor is connected to the first threaded rod 323, and the other motor is connected to the second threaded rod 325. Under the control of the controller, the first threaded rod 323 and the second threaded rod 325 can rotate in the same or opposite directions. In this case, the threads of the first threaded rod 323 and the second threaded rod 325 no longer have a rotation direction requirement.

[0045] In addition, the dual-axis motor 322 can be replaced with a regular motor, with only one connecting rod remaining. One of the first clamping arm 311 and the second clamping arm 312 can move while the other is set to be fixed, which can achieve the same technical effect.

[0046] like Figure 1 and Figure 3 As shown, in a preferred embodiment of the present invention, the power unit 32 further includes: a first bearing 327 and a second bearing 328. The first threaded rod 323 is rotatably connected to one side of the inner wall of the power unit housing 321 via the first bearing 327. The second threaded rod 325 is rotatably connected to the other side of the inner wall of the power unit housing 321 via the second bearing 328.

[0047] Specifically, the first threaded rod 323 and the second threaded rod 325 are arranged along the same straight line. Therefore, the first bearing 327 and the second bearing 328 are located on opposite sides of the inner wall of the power unit housing 321. One end of the first threaded rod 323 and the second threaded rod 325 can be fixedly connected to the inner ring of the first bearing 327 and the second bearing 328, respectively, thereby reducing wear during the rotation of the threaded rods through the arrangement of bearings.

[0048] like Figure 1 and Figure 2 As shown, in a preferred embodiment of the present invention, an adjustment port is provided on one side of the power unit housing 321, and the power unit 32 further includes a door and a handle. The door is rotatably disposed on one side of the adjustment port, so as to close the adjustment port and thus close the power unit housing 321 by rotating it. The handle is installed on the door, so as to open or close the door by pushing or pulling the handle. Thus, the door and handle of the housing are connected, making it convenient for users to clean the inside and maintain the equipment in good condition.

[0049] Specifically, the size of the opening is adjusted to facilitate cleaning of the first inner cavity 3211 of the power unit 32. The door can be opened or closed by pushing or pulling the handle. When the door is open, the first inner cavity 3211 and its internal components can be cleaned. When the door is closed, it prevents the internal components from contacting the external environment, thus ensuring that the operation of the dual-axis motor 322 is unaffected by external conditions.

[0050] like Figure 1 and Figure 2 As shown, in a preferred embodiment of the present invention, the power cord anti-pull mechanism further includes a spring-back device 4, which is disposed on both sides of the power socket 21 and is used to pop out the power cord 1 when the power cord 1 is released from the limit.

[0051] Specifically, the rebound device 4 can store elastic potential energy when the power line 1 is limited, so that the power line 1 can be ejected when the power line 1 is released from the limit, thereby achieving automatic power cut-off.

[0052] like Figure 1 and Figure 2As shown, in a preferred embodiment of the present invention, support plates 111 are provided on both sides of the power plug 11. The spring-loaded device 4 includes a spring-loaded housing 41, a horizontal plate 42, a damper 43, a spring 44, a connecting block 45, and a connecting plate 46. A second inner cavity 411 is formed inside the spring-loaded housing 41. The horizontal plate 42 is located in the second inner cavity 411 and is slidably connected to the side wall of the spring-loaded housing 41. One end of the damper 43 is connected to the bottom inner wall of the spring-loaded housing 41. The spring 44 is wound around the outside of the damper 43. One end of the connecting block 45 is connected to the other end of the damper 43, and the other end of the connecting block 45 is connected to the connecting plate 46. When the power cord 1 is limited, the horizontal plate 42 compresses the spring 44. When the power cord 1 is released from the limit, the damper 43 ejects the power cord 1 through the spring force of the spring 44.

[0053] Specifically, the spring-loaded housing 41 can also be a cuboid-shaped housing. Within the second inner cavity 411 of the spring-loaded housing 41, a damper 43, a connecting block 45, and a connecting plate 46 are arranged sequentially from left to right. A spring 44 is provided on the outside of the damper 43; specifically, the spring 44 is sleeved on the outside of the damper 43. When the power plug 11 is inserted into the power socket 21, the support plate 111 of the power plug 11 pushes the connecting plate 46, the connecting block 45, and the damper 43 to move from right to left, thereby compressing the spring 44 to store elastic potential energy. When the power plug 11 is released from its limit, the spring 44 releases its elastic potential energy, thereby causing the damper 43, the connecting block 45, and the connecting plate 46 to move from left to right, thus popping out the power plug 11. This eliminates the need for manual unplugging of the power plug 11, achieving automatic power cut-off and preventing injury to workers due to electrical leakage or other safety hazards.

[0054] Preferably, the support plate 111 is located on both sides of the power plug 11, corresponding to the position of the connecting plate 46.

[0055] Preferably, the damper 43 can be cylindrical. An annular groove is provided in the middle of the damper 43, and the spring 44 is encircled in the annular groove with the assistance of the rebound housing 41.

[0056] like Figure 1 and Figure 2 As shown, in a preferred embodiment of the present invention, the rebound device 4 further includes two slide grooves 47 and two sliders 48. The two slide grooves 47 are respectively formed on opposite sides of the inner sidewall of the rebound housing 41. The two sliders 48 are respectively mounted on the two ends of the horizontal plate 42 and are slidably disposed in the corresponding two slide grooves 47 to slide along the two slide grooves 47.

[0057] Specifically, a long, narrow groove 47 is formed on each opposite side of the inner wall of the spring shell 41, which is separated by the second inner cavity 411. The direction of the groove 47 is along the length of the spring shell 41. Two sliders 48 are respectively engaged in the two grooves 47, allowing them to slide back and forth along the grooves 47. The cross plate 42 can be narrow. However, the arrangement of the groove 47 and slider 48 mechanism can effectively reduce the vibration of the cross plate 42 during movement.

[0058] Preferably, reinforcing ribs can also be provided for the horizontal plate 42 to reduce the shaking of the horizontal plate 42 during movement.

[0059] like Figures 1-3 As shown, an embodiment of the present invention also discloses an industrial six-axis robot, which includes the aforementioned power cord anti-pull mechanism.

[0060] Among them, the power cord anti-pull mechanism for industrial six-axis robots can effectively prevent problems such as poor power cord contact and sudden power outages caused by pulling during operation. Moreover, after the industrial six-axis robot stops working, there is no need to manually unplug the power cord, which effectively achieves automatic power-off and prevents workers from being injured due to safety hazards such as leakage.

[0061] In a preferred embodiment of the present invention, the power cord anti-pull mechanism is an automatic control device.

[0062] Specifically, a controller is set up for the power cord anti-pull mechanism to automatically control its movement, which is conducive to its efficient operation.

[0063] In summary:

[0064] 1. This invention uses a power cord anti-pull mechanism to limit the pulling action of the power cord, preventing the power cord and power socket from being pulled apart, maintaining a stable connection, and avoiding poor contact or sudden power outage.

[0065] 2. Furthermore, the present invention also designs an automatic power-off function for the power cord anti-pull mechanism. When the power cord is pulled out, the power is automatically cut off through the action of the spring and damper, without the need for manual operation by the user, thus improving safety and portability.

[0066] 3. Further preferred embodiment of the present invention adopts a dual-axis motor to drive the threaded rod and threaded sleeve to move. The threaded sleeve drives the connecting rod and threaded sleeve to move, and the threaded sleeve drives the connecting rod and clamping arm to move, thereby limiting the power cord and solving the problem of poor contact or power failure caused by power cord pulling in the prior art.

[0067] 4. The automatic control of the power cord anti-pull mechanism can effectively and automatically cut off the power to operating equipment, especially industrial robots, without requiring users to manually unplug the power cord, thus preventing workers from being injured due to safety hazards such as leakage.
