[0037] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0038] See also Figure 1The present embodiment provides a method for processing a metal slide rail 1. The metal slide rail 1 includes a fixed slide rail 11, a movable slide rail 12, and a ball bar 13 disposed between the fixed slide rail 11 and the movable slide rail 12. The ball bar 13 includes a mounting bar 131 and a ball 132. The mounting bar 131 is provided with a ball hole. The ball 132 is placed in the ball hole. The ball 132 and the fixed slide rail 11 and the movable slide rail 12 all form a sliding pair. The processing method includes the following steps:

[0039] S1: transporting a mounting strip 131 and a plurality of balls 132 to the ball strip assembly station 21 respectively;

[0040] S2: Install the ball 132 into each ball hole on the mounting strip 131 to obtain the ball strip 13;

[0041] S3: transporting the two ball bearing bars 13 and the fixed slide rail 11 to the fixed slide rail assembly station 22 respectively;

[0042] S4: Assembling the two ball bearing strips 13 to the inner walls of the fixed slide rail 11 on opposite sides respectively, so as to obtain an assembly of the fixed slide rail 11;

[0044] S6: Assemble the movable slide rail 12 between the two ball bearing bars 13 in the fixed slide rail 11 assembly to obtain the metal slide rail 1.

[0045] It can be understood that the processing method of this embodiment realizes the automated assembly of the ball bar 13, the fixed slide rail 11 and the movable slide rail 12 by automatically controlling the transportation and assembly process of each component, and can continuously and efficiently complete the assembly process of the slide rail, thereby significantly improving production efficiency, reducing material handling and waiting time, and reducing production costs.

[0046] For further information, see Figures 2 to 8In step S1, the installation strip 131 is transported to the ball strip assembly station 21 by the first conveying mechanism 2, and the balls 132 are transported to the ball strip assembly station 21 by the suction cup conveying mechanism 3, and the suction cup conveying mechanism 3 is located above the first conveying mechanism 2 at the ball strip assembly station 21. In this embodiment, the first conveying mechanism 2 is responsible for transporting the installation strip 131 from the storage or the previous processing station to the ball strip assembly station 21, and the suction cup conveying mechanism 3 is located above the first conveying mechanism 2, which is responsible for adsorbing and transporting the balls 132 from the storage or the previous processing station to the ball strip assembly station 21, while ensuring the precise alignment of the balls 132 with the installation strip 131, and accurately placing the balls 132 in the ball holes of the installation strip 131. By combining the first conveying mechanism 2 and the suction cup conveying mechanism 3, the installation strip 131 and the balls 132 are transported quickly and continuously, which significantly improves the production efficiency.

[0047] Specifically, the first conveying mechanism 2 includes: a first conveying motor, a transmission wheel group and a first conveyor belt. The first conveyor is connected to the first conveyor belt through the transmission wheel group. The first conveying motor is used to drive the transmission wheel group to drive the first conveyor belt to rotate. The first conveyor belt is used to drive the material placed on its upper surface to move. Optionally, the transmission wheel group is composed of a plurality of transmission wheel shafts connected by the first conveyor belt, and the first conveying motor is connected to one of the plurality of transmission wheel shafts located at both ends of the first conveyor belt. The first conveying mechanism 2 realizes rapid and continuous transportation of materials by continuously rotating the first conveyor belt, thereby significantly improving production efficiency.

[0048] Further, in step S3, the ball bearing strip 13 is transported to the fixed rail assembly station 22 by the first conveying mechanism 2, and the fixed rail 11 is transported to the fixed rail assembly station 22 by the second conveying mechanism 4. Optionally, the second conveying mechanism 4 is a six-axis robot arm.

[0049] Further, in step S5, the fixed slide rail 11 assembly is transported to the movable slide rail assembly station 23 by the first conveying mechanism 2, and the movable slide rail 12 is transported to the movable slide rail assembly station 23 by the third conveying mechanism 5. Optionally, the third conveying mechanism 5 is a six-axis robot arm.

[0050] Specifically, in this embodiment, the installation bar 131 is transported to the ball bar assembly station 21 by the first conveying mechanism 2, and the ball bar 13 is obtained after being assembled with the ball 132. The ball bar 13 is further transported to the fixed slide rail assembly station 22 by the first conveying mechanism 2, and the fixed slide rail 11 assembly is obtained after being assembled with the fixed slide rail 11. The fixed slide rail 11 assembly is further transported to the movable slide rail assembly station 23 by the first conveying mechanism 2, and the metal slide rail 1 proposed in this embodiment is obtained after being assembled with the movable slide rail 12. It can be understood that this embodiment uses a continuous first conveying mechanism 2, starting from the ball bar assembly station 21, passing through the fixed slide rail assembly station 22 and the movable slide rail assembly station 23 in sequence, and finally completing the processing of the metal slide rail 1, ensuring the continuity and smoothness of the material during the processing process. By accurately controlling the speed and position of the first conveying mechanism 2, the accurate placement and processing of the material at each station can be ensured, thereby improving the precision and quality of the metal slide rail 1.

[0051] Specifically, the suction cup conveying mechanism 3 includes: a first driving device 31, a second driving device 32 and a plurality of adsorption devices 33. The first driving device 31 is used to drive the second driving device 32 to move to the top of the first conveying mechanism 2 at the ball bar assembly station 21. The second driving device 32 is used to drive the plurality of adsorption devices 33 to be arranged at a specified interval. The adsorption devices 33 are used to vacuum adsorb the balls 132. In a feasible action process, when the first conveying mechanism 2 transports the ball bar 13 to the ball bar assembly station 21, the first driving device 31 is started to drive the entire suction cup conveying mechanism 3 to move to the specified position above the ball bar 13. The second driving device 32 is started to drive the plurality of adsorption devices 33 to be arranged at a specified interval according to the placement requirements of the balls 132 of the ball bar 13. Under the command of the control system, the adsorption devices 33 accurately place the balls 132 at the specified positions of the ball bar 13. The balls 132 are quickly and accurately placed by automated means, which significantly improves production efficiency.

[0052] Furthermore, the second driving device 32 is a linear motor with multiple movers 321, and the multiple movers 321 of the linear motor are connected to the multiple adsorption devices 33 in a one-to-one correspondence; the suction cup transmission mechanism 3 also includes a first alignment detection camera, which is used to detect the arrangement of the ball holes on the mounting strip 131. The control system of the second driving device 32 controls the intervals between the movers 321 according to the detection data of the first alignment detection camera, so that the interval arrangement of the multiple movers 321 on the first driving device 31 is the same as the interval arrangement of the multiple ball holes on the mounting strip 131. It can be understood that in the assembly process of the ball strip 13 of the metal slide rail 1, it is very important to ensure that the ball 132 is accurately and correctly placed in the ball hole. In this embodiment, the second driving device 32 adopts a linear motor with multiple movers 321, and each mover 321 is connected to a suction device 33 in a one-to-one correspondence, so that each suction device 33 can move independently and accurately, thereby realizing accurate control of the placement position of the ball 132. In a feasible action process, when the first conveying mechanism 2 transports the mounting bar 131 to the ball bar assembly station 21, the first alignment detection camera is activated to detect the ball holes on the mounting bar 131 in real time, and transmit the detection data to the control system. The control system calculates the position and distance that each mover 321 needs to move, as well as the interval between the movers 321, based on the detection data and the preset placement requirements of the balls 132. The second drive device 32 controls the multiple movers 321 of the linear motor to move to the specified position based on the calculation results, so that the spacing arrangement of the adsorption device 33 matches the spacing arrangement of the ball holes. Under the command of the control system, the adsorption device 33 accurately places the balls 132 in the ball holes of the mounting bar 131. According to the number and placement requirements of the ball holes on the mounting bar 131, the suction cup conveying mechanism 3 repeats the above operation until all the balls 132 are accurately placed.

[0053] Furthermore, the suction cup conveying mechanism 3 also includes a second alignment detection camera, which is used to detect the position and placement angle of the installation bar 131 at the ball bar assembly station 21. The control system of the second drive device 32 controls the movement of the second drive device 32 according to the detection data of the second alignment detection camera, so that the second drive device 32 moves to the top of the installation bar 131. In a feasible action process, when the first conveying mechanism 2 transports the installation bar 131 to the ball bar assembly station 21, the second alignment detection camera is started to perform real-time detection of the installation bar 131 and obtain its position and angle information. The control system calculates the position and angle that the second drive device 32 needs to move according to the detection data to ensure that the adsorption device 33 can accurately move to the top of the installation bar 131. Under the instruction of the control system, the second driving device 32 starts and accurately adjusts the position of the adsorption device 33 so that the adsorption device 33 matches the position and angle of the mounting bar 131. After the adsorption device 33 moves to directly above the mounting bar 131, the control system adjusts the spacing of the adsorption device 33 according to the detection data of the first alignment detection camera to ensure that the ball 132 can be accurately placed in the ball hole.

[0054] Specifically, the adsorption device 33 includes an adsorption block 331 and a vacuum pump 332. The adsorption block 331 and the vacuum pump 332 are both fixed on the mover 321 of the second drive device 32. A vacuum chamber is provided in the adsorption block 331. The suction end of the vacuum pump 332 is connected to the vacuum chamber. A spherical adsorption groove 3311 is concavely provided on the lower side of the adsorption block 331. The groove wall of the spherical adsorption groove 3311 is provided with an adsorption hole, and the adsorption hole is connected between the vacuum chamber and the spherical adsorption groove 3311. It can be understood that the vacuum pump 332 generates negative pressure in the vacuum chamber through suction. When the spherical adsorption groove 3311 on the lower surface of the adsorption block 331 is in close contact with the surface of the object, the air between the object and the spherical adsorption groove 3311 is extracted to form a partial vacuum, thereby generating a strong adsorption force to firmly adsorb the object on the adsorption block 331. The mover 321 of the second drive device 32 is responsible for driving the entire adsorption device 33 to move to achieve the functions of adsorbing, transporting and releasing the object.

[0055] Specifically, the first driving device 31 is a six-axis robotic arm, which is used to drive the second driving device 32 to displace and / or rotate. The six-axis robotic arm includes a base, a first rotating arm, a second rotating arm, a third rotating arm, a fourth rotating arm, a fifth rotating arm and a sixth rotating arm. A first driving motor is provided between the first rotating arm and the base to drive the first rotating arm to rotate relative to the base; a second driving motor is provided between the second rotating arm and the first rotating arm to drive the second rotating arm to rotate relative to the first rotating arm; a third driving motor is provided between the third rotating arm and the second rotating arm to drive the third rotating arm to rotate relative to the second rotating arm; a fourth driving motor is provided between the fourth rotating arm and the third rotating arm to drive the fourth rotating arm to rotate relative to the third rotating arm; a fifth driving motor is provided between the fifth rotating arm and the fourth rotating arm to drive the fifth rotating arm to rotate relative to the fourth rotating arm; a sixth driving motor is provided between the sixth rotating arm and the fifth rotating arm to drive the sixth rotating arm to rotate relative to the fifth rotating arm, and the second driving device 32 is connected to the end of the sixth rotating arm. It can be understood that each rotating arm of the six-axis robotic arm achieves relative rotation through a drive motor, thereby constructing a mechanical structure that can move freely in three-dimensional space. Each drive motor is equipped with a corresponding reducer, sensor (such as an encoder) and control circuit to ensure the accuracy and stability of the movement. By controlling the rotation angle and speed of each motor, precise control of the position and posture of the end of the robotic arm can be achieved. The six-axis robotic arm of this embodiment can perform complex motion control in three-dimensional space and can adapt to various complex working environments and task requirements.
