[0075] In the embodiment, the rack is fixed on the horizontal slide rail through a plurality of oppositely arranged positioning bolts.

[0076] By arranging the rack parallel to the slide rail outside the slide rail and matching the first and second gears connected with the motor output shaft, precise power transmission and motion control are achieved. In addition, the design of the first and second positioning wheel sets ensures the stable operation of the moving assembly along the slide rail, and the arrangement of the first and second pulley sets reduces friction and improves moving efficiency. The symmetrical arrangement not only enhances the carrying capacity of the mechanical hand, but also ensures the coordination and synchronization in two horizontal directions, so that the mechanical hand can smoothly and accurately move heavy objects, improving work efficiency and safety.

[0077] Specifically, the first positioning wheel group 151 includes four positioning wheels, which are evenly distributed on both sides of the first slide rail and located at one end of the bottom of the horizontal first base 121.

[0078] The second positioning wheel group 152 includes four positioning wheels, which are evenly distributed on both sides of the first slide rail and located at the end of the bottom of the horizontal first base 121 away from the first positioning wheel group 151.

[0079] In the embodiment, the third positioning wheel group 153 is arranged in the same position as the first positioning wheel group 151 on both sides of the first slide rail and the first positioning wheel group 151 on the bottom of the horizontal first base 121, and the fourth positioning wheel group 154 is arranged in the same position as the second positioning wheel group 152 on both sides of the first slide rail and the second positioning wheel group 152 on the bottom of the horizontal first base 121.

[0080] The moving pulley is located in the middle of the positioning wheel group, and the bottom of both ends of the base is provided with four holes for installing the positioning wheel, and the positioning wheel is fixed on the base through a nut. The side surface of both ends of the base is provided with a moving pulley mounting hole for installing and fixing the moving pulley.

[0081] By positioning the wheels evenly on both sides of the first slide rail and setting the first and second groups of positioning wheels at the two ends of the bottom of the horizontal first base, uniform force and good contact of the mechanical arm during movement along the slide rail are ensured, thereby reducing deviation and vibration. In addition, the third and fourth groups of positioning wheels are arranged in the same position relationship as the first and second groups of positioning wheels, and the symmetrical layout further improves the stability of the mechanical arm. The moving pulley is located in the middle of the positioning wheel group, and the positioning wheels are fixed by the hole and nut, so that the structure is compact, easy to install, and convenient for maintenance and replacement.

[0082] Specifically, the first horizontal moving assembly cooperates with the horizontal first slide rail 111, and the second horizontal moving assembly cooperates with the horizontal second slide rail 112.

[0083] In implementation, the first horizontal moving assembly and the second horizontal moving assembly move synchronously, and the first motor and the second motor have the same rotating speed when working.

[0084] Specifically, the second slide rail group is fixed on the top of the fixed frame 23, and the horizontal plane second direction in which the second slide rail group is laid is perpendicular to the horizontal plane first direction.

[0085] In implementation, the second slide rail group is arranged on the fixed frame 23, and the second slide rail group is installed to the horizontal second direction by installing the rectangular metal frame to the top of the first base 121 and the top of the second base 122.

[0086] Please refer to Figure 4 The third horizontal moving assembly includes:

[0087] The third rack 22 is arranged inside the horizontal third slide rail 211 and parallel to the horizontal third slide rail, and the fourth rack is arranged inside the horizontal fourth slide rail 212 and parallel to the fourth slide rail;

[0088] The third motor 28 is arranged inside the horizontal third slide rail 211 and connected to the base 27, and the output shaft of the third motor 28 is parallel to the vertical moving mechanism;

[0092] By arranging the parallel third rack and fourth rack inside the horizontal third slide rail and fourth slide rail respectively, and corresponding third motor and third gear, the effective transmission of power and precise control of movement are ensured. The third positioning wheel set makes the contact between the base and the slide rail more stable, reducing friction and wear during movement, and the arrangement of the third pulley set further reduces friction, improves the flexibility and speed of movement.

[0097] By evenly distributing the positioning wheels on both sides of the third and fourth slide rails, and arranging the positioning wheel groups at both ends of the base respectively, this symmetrical layout helps to disperse the load and reduce wear caused by uneven stress. The design of the moving pulley located in the middle of the positioning wheel group makes the force transmission more uniform, reduces the friction between the slide rail and the moving assembly, and thus improves the moving efficiency. In addition, by arranging holes and mounting pieces on the base plate to fix the positioning wheels and the moving pulley, this structure not only facilitates installation and maintenance, but also enhances the rigidity and durability of the overall structure, so that the mechanical hand can work stably for a long time under heavy load conditions.

[0104] In implementation, the two sides of the fixed frame 33 moving hole are respectively connected to the vertical first slide rail 311 moving hole and the vertical second slide rail 312 moving hole.

[0105] The edges of the vertical first slide rail 311 moving hole and the vertical second slide rail 312 moving hole are also provided with positioning grooves of the vertical first slide rail 311 and the vertical second slide rail 312, so that the two slide rails move in the vertical direction.

[0106] Specifically, the vertical movement mechanism further includes a wire slot arranged on the opposite side of the fixed frame 33 to the lead screw.

[0107] Working process:

[0108] When moving in the first horizontal direction, the first horizontal moving mechanism drives the first gear 141 through the first motor, and the first gear 141 is engaged with the first rack 131, so that the first horizontal moving assembly moves horizontally along the first horizontal slide rail 111 and the second horizontal slide rail; when moving in the second horizontal direction, the second horizontal moving mechanism drives the third gear 24 through the third motor 28, and the third gear 24 is engaged with the third rack 22 and the fourth rack, so that the third horizontal moving assembly moves horizontally along the third horizontal slide rail 211 and the fourth horizontal slide rail in the other direction; the vertical moving mechanism drives the screw assembly 32 through the fourth motor 34, so that the vertical moving assembly moves vertically along the first vertical slide rail and the second vertical slide rail, thereby realizing accurate positioning of the mechanical hand in the vertical direction.
