[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.
[0028] The structures, proportions, and sizes illustrated in the accompanying drawings are merely for illustrative purposes and to aid those skilled in the art. They are not intended to limit the scope of this invention and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, provided they do not affect the effectiveness or purpose of this invention, should still fall within the scope of the technical content disclosed herein. Furthermore, the terms "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.
[0029] like Figures 1 to 6 As shown, a preferred embodiment of an industrial robotic arm cable package is illustrated, which includes: a base 16, a first arm 1, a second arm 2, a third arm 3, a fourth arm 4, a fifth arm 5, and a cable 6.
[0030] The first shaft arm 1 is mounted on the base 16, and the first shaft arm 1, the second shaft arm 2, the third shaft arm 3, the fourth shaft arm 4, and the fifth shaft arm 5 are hinged in sequence; wherein the second shaft arm 2 includes: a mounting base 21, a balance cylinder 22, and the shaft arm 21; the shaft arm 21 is mounted on the first shaft arm 1 through the mounting base; both ends of the balance cylinder 22 are mounted on the mounting base 21 through two movable brackets 24, and the output shaft of the balance cylinder 22 is mounted on the shaft arm 21; the base 16 is provided with a through hole 13; the pipeline 6 enters from the base 16, passes through the through hole 13, extends around one end of the shaft arm 23 to the other end of the shaft arm 23, then passes through the third shaft arm 3 and the fourth shaft arm 4, and finally exits at the fifth shaft arm 5.
[0031] In actual use, a through hole 13 is added at the position of the base 16, so that the pipeline 6 can be wrapped around the robot, which increases the range of motion of the pipeline 6, and better prevents the pipeline 6 from contacting the robot, preventing damage to the pipeline 6 and increasing the service life of the pipeline 6.
[0032] Based on the above, this utility model also has the following embodiments:
[0033] Furthermore, an industrial robotic arm cable package further includes: a power supply box; one end of the cable 6 is installed in the power supply box, and the other end of the cable 6 passes through the through hole 13.
[0034] Furthermore, an industrial robotic arm cable package further includes: a plurality of first fixing blocks 7; the plurality of first fixing blocks 7 are installed on the shaft arm 23, and a portion of the cable 6 is fixed to the shaft arm 23 by the plurality of first fixing blocks 7. A section of the cable 6 is arranged in a "U" shape around the shaft arm 23, forming a U-shaped cable segment 9. The bottom end of the U-shaped cable segment 9 is fixed to the mounting base 21 by a second fixing block 11. The outer wall of the U-shaped cable segment 9 is covered with a wear-resistant and flame-retardant cloth. Specifically, the arrangement of the U-shaped cable segment 9 allows the cable to have a greater range of motion, and the wear-resistant and flame-retardant cloth with a thickness of about 1.5mm is wrapped around the U-shaped cable segment 9. The solution of using wear-resistant and flame-retardant cloth solves the problem of poor flexibility of traditional plastic protective tubes for cable, and the method of tearing open the wear-resistant and flame-retardant cloth for maintenance is very convenient when replacing the cable in the cable harness of the cable 6.
[0035] Furthermore, an industrial robotic arm cable package further includes: a plurality of third fixing blocks 8; the plurality of third fixing blocks 8 are respectively installed on the third axis arm 3, the fourth axis arm 4, and the fifth axis arm 5; a portion of the cable 6 is installed on the third axis arm 3, the fourth axis arm 4, and the fifth axis arm 5 through the plurality of third fixing blocks 8; the cable 6 located on the third axis arm 3 and the fourth axis arm 4 has a slack; the cable 6 is also installed on the fifth axis arm 5 through a movable limiting block 12; the fifth axis arm 5 is also equipped with a C-shaped clamping flange 14 and a tool side 15; the cable 6 passes through the movable limiting block 12 and the C-shaped clamping flange 14 in sequence, and is finally fixed to the tool side 15; a cable segment is formed between the C-shaped clamping flange 14 and the third fixing block 8 of the fourth axis arm 4; a carbon steel tension spring 10 is sleeved on the outer wall of the cable segment. Specifically, the carbon steel tension spring 10 has a very small elastic force but very good rigidity and good flexibility when subjected to external pressure, so as to protect the internal cable 6 and reduce the risk of excessive entanglement of the highly flexible cable on the robotic arm.
[0036] In actual use, the pipeline 6 is inserted through the through hole 13, fixed at the lower position by the first fixing block 7 and the second fixing block 11, and then fixed at the upper position of the robot by several third fixing blocks 8. A U-shaped pipeline section 9 of about 1.5m is reserved at the lower position of the pipeline 6. Then the pipeline 6 passes through the movable limiting block 12 and the C-type clamping flange, and is finally fixed in the tool side. The pipeline 6 swings on the arm. In order to prevent the pipeline harness from rubbing against the arm, a cover is used to protect the robot arm.
[0037] Furthermore, an industrial robotic arm cable package includes a movable limiting block 12 comprising two limiting blocks 18 and a mounting bracket 17. The mounting bracket 17 is mounted on the fifth axis arm 5, and the two limiting blocks 18 are mounted on the mounting bracket 17. The cable 6 is fixed between the two limiting blocks 18. Specifically, the two limiting blocks 18 are arc-shaped, increasing the range of motion of the cable 6 harness. Compared to traditional methods where the cable is fixed to the robot axis by only a cylindrical clamp, the use of the movable limiting block 12 better prevents the cable 6 from contacting the robot arm, thus preventing damage.
[0038] Specifically, in another preferred embodiment, the two movable limiting blocks 18 and the mounting bracket 17 can be installed in a rotatable manner, so that the two movable limiting blocks 18 can rotate relative to the mounting bracket 17, so that the pipeline 6 has more room to move between the two movable limiting blocks 18.
[0039] Furthermore, an industrial robotic arm cable package includes a limit stop that is arc-shaped.
[0040] Furthermore, an industrial robotic arm cable package, wherein the thickness of the wear-resistant and flame-retardant cloth is 1.5 mm.
[0041] Furthermore, an industrial robotic arm cable package, wherein the carbon steel tension spring 10 has a diameter of φ72mm.
[0042] Furthermore, an industrial robotic arm cable package is provided, wherein the first fixing block 7, the second fixing block 11, and the third fixing block 8 are all cylindrical hollow sleeve structures.
[0043] Furthermore, in an industrial robotic arm cable package, the first fixing block 7, the second fixing block 11, and the third fixing block 8 are all fixed by screws, and the cable 6 passes through the first fixing block 7, the second fixing block 11, and the third fixing block 8. Specifically, fixing the first fixing block 7, the second fixing block 11, and the third fixing block 8 by screws simplifies the installation and disassembly of the first fixing block 7, the second fixing block 11, and the third fixing block 8.
[0044] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
