[0054] In order to be able to more clearly understand the above objects, features and advantages of the present utility model, the present utility model will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.
[0055] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present utility model is not limited by the specific embodiments disclosed below.
[0056] Next, refer to Figures 1 to 10 Describe the robotic arm and robot proposed according to some embodiments of the present utility model.
[0057] As Figure 1 、 Figure 2 、 Figure 3 and Figure 4 shown, according to an embodiment of the present utility model, the present utility model provides a robotic arm, comprising: a connecting arm 1, a first shaft portion 2, a second shaft portion 3, a first fixing portion 4, a second fixing portion 5, and a cable bundle 6.
[0058] Specifically, the first shaft portion 2 is disposed on the connecting arm 1, and the first shaft portion 2 has a first rotation axis B; the second shaft portion 3 has a second rotation axis C, and the second shaft portion 3 is disposed on the first shaft portion 2 and can rotate about the first rotation axis B with the first shaft portion 2; the first fixing portion 4 is disposed at an end of the first shaft portion 2, and at least a part of the first fixing portion 4 can rotate relative to the first shaft portion 2; the second fixing portion 5 is disposed at an end of the second shaft portion 3; the cable bundle 6 is movably connected to the first fixing portion 4, and one end of the cable bundle 6 is disposed on the second fixing portion 5.
[0059] The robotic arm provided by the present utility model comprises a connecting arm 1, a first shaft portion 2, a second shaft portion 3, a first fixing portion 4, a second fixing portion 5, and a cable bundle 6. The first shaft portion 2 is disposed on the connecting arm 1 and can rotate about the first rotation axis B. The second shaft portion 3 is disposed on the first shaft portion 2 and can thus rotate about the first rotation axis B with the first shaft portion 2. At the same time, the second shaft portion 3 has a second rotation axis C, such that the second shaft portion 3 can rotate about the second rotation axis C itself, increasing the degrees of freedom of the robotic arm and making the robotic arm more flexible. Among them, the first fixing portion 4 is disposed at an end of the first shaft portion 2, the second fixing portion 5 is disposed at an end of the second shaft portion 3, the cable bundle 6 is movably connected to the first fixing portion 4, and one end of the cable bundle 6 is disposed on the second fixing portion 5. When the robotic arm is working, the cable bundle 6 is constrained at both the first shaft portion 2 and the second shaft portion 3, reducing the fluctuation range of the cable bundle 6, ensuring the minimum distance between the cable bundle 6 and the robot hand, and also enhancing the installation strength of the cable bundle 6. At the same time, at least a part of the first fixing portion 4 can rotate relative to the first shaft portion 2, and the cable bundle 6 is movably connected to the first fixing portion 4, so that the cable bundle 6 can expand and contract with the movement of the first shaft portion 2 and the second shaft portion 3, avoiding affecting the actual working range of the first shaft portion 2.
[0060] It can be understood that the cable bundle 6 can extend from the connecting arm 1 to the first shaft portion 2 and the second shaft portion 3.
[0061] As Figure 1 、 Figure 4 and Figure 5 shown, in some embodiments, optionally, the first fixing portion 4 comprises: a bracket 40 and a rotating seat 42.
[0062] Specifically, the bracket 40 is installed at the end of the first shaft portion 2; the rotating seat 42 is rotatably connected to the bracket 40, and the pipeline package 6 passes through the rotating seat 42 and is movably connected to the rotating seat 42.
[0063] In this embodiment, the first fixing portion 4 includes the bracket 40 and the rotating seat 42. The bracket 40 is installed at the end of the first shaft portion 2. The rotating seat 42 is rotatably connected to the bracket 40 and sleeved outside the pipeline package 6 to limit the pipeline package 6 and shorten the distance between the pipeline package 6 and the first shaft portion 2. At the same time, sleeving the rotating seat 42 outside the pipeline package 6 also improves the connection strength between the rotating seat 42 and the pipeline package 6, thereby avoiding the situation of the pipeline package 6 falling off during operation.
[0064] Optionally, the rotating seat 42 includes a through hole, and the pipeline package 6 passes through the through hole and can move relative to the through hole. Optionally, the axis of the through hole is perpendicular to the first rotation axis B.
[0065] Optionally, the pipeline package 6 can move in the through hole along the length direction of the pipeline package 6.
[0066] Optionally, the rotating seat 42 includes a first part and a second part, both of which are semi-circular. Thus, the first part and the second part are assembled outside the pipeline package 6, simplifying the connection process between the pipeline package 6 and the rotating seat 42.
[0067] As Figure 2 and Figure 4 shown, in some embodiments, optionally, the first fixing portion 4 further includes: a rotating member 44. One side of the rotating member 44 is connected to the bracket 40, and the other side of the rotating member 44 is connected to the rotating seat 42. The rotating seat 42 can rotate around the first rotation axis B through the rotating member 44.
[0068] In this embodiment, the first fixing portion 4 further includes a rotating member 44. The rotating seat 42 is rotatably connected to the bracket 40 through the rotating member 44, so that the pipeline package 6 can move with the movements of the first shaft portion 2 and the second shaft portion 3, avoiding affecting the actual movement stroke of the first shaft portion 2.
[0069] In some embodiments, optionally, the rotating member 44 includes a thrust bearing 440.
[0070] In this embodiment, the rotating member 44 includes a thrust bearing 440. The thrust bearing 440 can bear axial pressure. Thus, one axial side of the thrust bearing 440 is installed on the first shaft portion 2, and the rotating seat 42 is fixed on the other axial side of the thrust bearing 440, realizing the rotational connection between the rotating seat 42 and the bracket 40.
[0071] It can be understood that the bracket 40 is fixed on the first shaft portion 2, so that the entire first fixing portion 4 can move with the first shaft portion 2. At the same time, the rotating seat 42 can also rotate relative to the bracket 40 around the first rotation axis B. Therefore, the pipeline package 6 can also move relative to the first shaft portion 2. Furthermore, when the first shaft portion 2 or the second shaft portion 3 moves, interference between the pipeline package 6 and the first shaft portion 2 is avoided, which affects the movement of the first shaft portion 2 or the second shaft portion 3, and the flexibility of the robotic arm is improved.
[0072] As Figure 2 shown, in some embodiments, optionally, the first fixing portion 4 further includes: an adapter block 46. The adapter block 46 is disposed on the thrust bearing 440. One side of the adapter block 46 is connected to the thrust bearing 440, and the other side of the adapter block 46 is connected to the rotating seat 42.
[0073] In this embodiment, the first fixing portion 4 further includes an adapter block 46. The adapter block 46 is disposed between the thrust bearing 440 and the rotating seat 42, realizing the connection between the thrust bearing 440 and the rotating seat 42, and can also increase the distance between the bracket 40 and the rotating seat 42, avoiding interference between the rotating seat 42 and the bracket 40 when the rotating seat 42 rotates.
[0074] It can be understood that when the connection structure on the thrust bearing 440 does not correspond to the connection structure on the rotating seat 42 (for example, there are 3 connection holes on the thrust bearing 440 and 2 connection holes on the rotating seat 42), the connection between the thrust bearing 440 and the rotating seat 42 can be realized through the adapter block 46. Specifically, the connection structure on one side of the adapter block 46 can be set to correspond to the connection structure on the thrust bearing 440 (for example, the quantity and position are set to be the same or corresponding), and the connection structure on the other side of the adapter block 46 can be set to correspond to the connection structure on the rotating seat 42, so as to realize the connection between the thrust bearing 440 and the rotating seat 42.
[0075] As Figure 1 、 Figure 2 、 Figure 4 and Figure 5 shown, in some embodiments, optionally, the first fixing portion 4 further includes: a flexible sleeve 48. The rotating seat 42 is sleeved on the outer side of the flexible sleeve 48, and the pipeline package 6 passes through the flexible sleeve 48. The pipeline package 6 is movably connected to the flexible sleeve 48.
[0076] In this embodiment, the robotic arm further includes a flexible sleeve 48. The flexible sleeve 48 is sleeved on the outer side of the pipeline package 6, and the rotating seat 42 is sleeved on the outer side of the flexible sleeve 48, so that the rotating seat 42 and the pipeline package 6 are isolated by the flexible sleeve 48, avoiding wear of the pipeline package 6 during the movement of the pipeline package 6. The pipeline package 6 is movably connected to the flexible sleeve 48, enabling the pipeline package 6 to move within the flexible sleeve 48, improving the flexibility of the robotic arm.
[0077] As Figure 1 shown, in some embodiments, optionally, the flexible sleeve 48 includes: a first flexible shell 480; a second flexible shell 482, the first flexible shell 480 and the second flexible shell 482 are oppositely arranged and connected along the circumferential direction of the pipeline package 6 to cover the outer side wall of the pipeline package 6.
[0078] In this embodiment, the flexible sleeve 48 includes a first flexible shell 480 and a second flexible shell 482. The first flexible shell 480 and the second flexible shell 482 are connected, and then cover the outer side wall of the pipeline package 6, realizing the connection between the flexible sleeve 48 and the pipeline package 6.
[0079] Optionally, the first flexible shell 480 and the second flexible shell 482 are spliced together by a connecting member, improving the connection strength between the first flexible shell 480 and the second flexible shell 482.
[0080] In some embodiments, optionally, at least one end of the flexible sleeve 48 expands outward to form a horn-shaped structure.
[0081] In this embodiment, at least one end of the flexible sleeve 48 is in a horn-shaped structure. The setting of the horn-shaped structure can facilitate the installation of the pipeline package 6. At the same time, during the swinging process of the pipeline package 6, it can avoid the pipeline package 6 and prevent the edge part of the flexible sleeve 48 from wearing the pipeline package 6. In addition, the outward-expanded horn-shaped structure can also limit the maximum swinging range of the pipeline package 6.
[0082] It can be understood that the horn-shaped structure is located outside the rotating seat 42.
[0083] Optionally, the horn-shaped structure is located between the rotating seat 42 and the second fixing part 5.
[0084] Optionally, both ends of the flexible sleeve 48 are expanded outward to form horn-shaped structures.

The first flange 502 is connected to the end of the second shaft portion 3. The second flange 504 is connected to and disposed opposite the first flange 502. Thus, the connection of other components can be achieved through the second flange 504. The limiting member 52 is disposed on the flange member 50, and the pipeline package 6 is installed on the flange member 50 through the limiting member 52, shortening the distance between the end of the pipeline package 6 and the second shaft portion 3.
[0087] Optionally, the flange member 50 includes a casting.
[0088] As Figure 1 and Figure 5 shown, in some embodiments, optionally, a channel 506 is defined between the first flange 502 and the second flange 504. The pipeline package 6 is disposed through the channel 506. The limiting member 52 is located on the side of the flange member 50 away from the first fixing portion 4 and is connected to the first flange 502 or the second flange 504.
[0089] In this embodiment, a channel 506 is defined between the first flange 502 and the second flange 504. The pipeline package 6 is inserted from one end of the channel 506 to the other end of the channel 506, and then connected to the limiting member 52, shortening the distance between the pipeline package 6 and the second shaft portion 3, reducing the space occupied by the pipeline package 6, and enhancing the connection strength between the pipeline package 6 and the flange member 50.
[0090] As Figure 2 shown, in some embodiments, optionally, the limiting member 52 includes a clamp 520, and the clamp 520 is clamped on the pipeline package 6.
[0091] In this embodiment, the limiting member 52 includes a clamp 520, and the clamp 520 is clamped on the pipeline package 6, thereby realizing the fixation of the pipeline package 6 and enabling the pipeline package 6 to be installed at the end of the second shaft portion 3.

[0103] Optionally, the pipeline package 6 is wound from the first fixing part 4 around the bottom of the flange 50 to the top of the flange 50, and then clamped on the rib plate 508 by a clamp 520.
[0104] Optionally, the pipeline package 6 is clamped on at least two rib plates 508 by at least two clamps 520 to enhance the connection strength between the pipeline package 6 and the flange 50.
[0105] As Figure 1 and Figure 2 shown, in some embodiments, optionally, the robotic arm further includes: an adapter ring assembly 54, the adapter ring assembly 54 is disposed at one end of the pipeline package 6, and the limiting member 52 is connected to the adapter ring assembly 54.
[0106] In this embodiment, the robotic arm further includes an adapter ring assembly 54, the adapter ring assembly 54 is disposed at one end of the pipeline package 6, and further, the limiting member 52 is connected to the pipeline package 6 through the adapter ring assembly 54, realizing the connection between the second fixing part 5 and the pipeline package 6.
[0107] According to an embodiment of the present invention, a robot is further provided, including: the robotic arm as proposed in any of the above embodiments.
[0108] The robot provided by the present invention includes the robotic arm as proposed in any of the above embodiments, and thus has all the beneficial effects of the robotic arm.
[0109] In a specific application, the present application provides a structural component for restraining a pipeline package 6, including a flange casting with a through-channel on both sides (such as the flange 50), a positioning block 522, a fixing bracket for the A5 axis (such as the first shaft part 2) (such as the bracket 40), a thrust bearing 440, a clamp assembly (such as the clamp 520), an adapter ring assembly 54, a rotary fixing seat (such as the rotary seat 42), and a bell mouth assembly (such as the flexible sleeve 48).
[0110] On the basis of the original pipeline package 6, a bell mouth assembly is installed. At the same time, at the end of the pipeline package 6, the original end plastic assembly is replaced with an adapter ring assembly 54. Then, on the shaft end flange surface of the A6 axis (such as the second shaft part 3) of the robotic arm, a double-sided flange casting with a through-channel in the middle, a positioning block 522, and a clamp assembly are respectively installed. Among them, the positioning block 522 is installed on the flange casting, and the clamp assembly is installed on the positioning block 522. There are a fixed bracket, a thrust bearing 440, and a rotating fixed seat at the A5 axis. At this time, for the wiring harness at the A6 end of the pipeline package 6, first fix the bell mouth assembly to the rotating fixed seat on the fixed bracket, so that the wiring harness is constrained at the A5 axis, then pass through the through-channel (such as channel 506) of the casting, and at the end of the A6 axis, install the wiring harness into the clamp assembly on the positioning block 522 through the adapter ring assembly 54. During operation, the double-sided flange casting on the A6 axis will swing under the rotation of the flange of the A6 axis and the A5 axis. At this time, the corrugated pipe will pass through the bell mouth assembly of the A5 axis and achieve telescopic and swinging under the coordinated work of the bell mouth assembly and the thrust bearing 440. At the same time, it will be restricted by the clamp assembly on the double-sided flange of the A6 axis and the clamp 520 (such as the rotating fixed seat) on the A5 axis.
[0111] During operation, the pipeline package 6 is restricted at two points: the bell mouth at the A5 axis and the clamp assembly at the A6 axis flange. While reducing the large-range fluctuating movement of the pipeline package 6, it also ensures the minimum distance from the robotic arm.
[0112] The bell mouth assembly can not only ensure the telescopic movement of the corrugated pipe but also rotate by itself. Therefore, when the A5 axis drives the A6 axis flange and the flange casting to move, it can rotate freely along the direction of the corrugated pipe, avoiding collision with the robotic arm and improving the flexibility of the pipeline package 6.
[0113] The material strength of the fixed bracket, clamp 520, flange casting, etc. of the A5 axis has been improved. The fixing of the wiring harness is achieved by the structure of the clamps 520 at various places, and the load is shared by the double-sided flange casting, the fixed bracket of the A5 axis, the bearing, etc. Therefore, the fixing effect is greatly enhanced.
[0114] Optionally, the flange casting with a through-channel in the middle on both sides can adopt a three-ribbed plate type casting to achieve a similar function. The scheme of the positioning block 522 and the clamp assembly installed on the flange casting can be replaced with two symmetrical small casting components (such as limit blocks).
