DETAILED DESCRIPTION

[0017] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0018] For this example, please refer to Figures 1-11, which specifically implements a linear-driven high-speed feeder, including a shell 1, a working platform 2, a linear drive mechanism 3 and a clamping and feeding mechanism 4, wherein the linear drive mechanism 3 is composed of a linear motor, which is horizontally arranged inside the shell 1, and the working platform 2 is covered above the linear motor. The top surface of the linear motor is a horizontally movable driving platform 34, and the clamping and feeding mechanism 4 is composed of a movable clamping arm 41 and a fixed clamping arm 42. The movable clamping arm 41 and the fixed clamping arm 42 are both provided with a clamping assembly 43 for fixing the material. The fixed clamping arm 42 is fixedly connected to one end of the working platform 2, and a first air avoidance groove 21 is opened in the middle of the working platform 2. The first air avoidance groove 21 is opened in a long strip structure along the moving direction of the driving platform 34, and the bottom end of the movable clamping arm 41 can pass through the first air avoidance groove 21 and extend to the interior of the shell 1 to be fixedly connected to the driving platform 34.

[0019] The movable clamping arm 41 is driven by the linear drive mechanism 3 composed of a linear motor. The bottom end of the movable clamping arm 41 can pass through the first air avoidance groove 21 and extend to the interior of the shell 1 to be fixedly connected to the drive platform 34, so that the movable clamping arm 41 can be driven by the linear motor and perform horizontal linear motion following the movement direction of the drive platform 34. At the same time, the movable clamping arm 41 cooperates with the fixed clamping arm 42 to complete the alternating clamping action on the clamping assembly 43. The present invention can complete the high-speed feeding action by driving the movable clamping arm 41 through the movement of the linear motor. At the same time, the movement stroke range and length of the linear motor can be changed by the node driven by the motor. It has the characteristics of fast adjustment and high precision, and can be completed without setting up a complex mechanical transmission structure.

[0020] Specifically, such as Figure 2 and Figure 3 As shown, the linear motor also includes a base 31, a stator 32 and a mover 33. The stator 32 is composed of a plurality of coils, and the plurality of coils are distributed in a linear array structure inside the base 31. The mover 33 is composed of a permanent magnet. The bottom two sides of the mover 33 are movably connected to the two sides of the stator 32 through linear guides 35. The drive platform 34 is fixedly connected to the top of the mover 33. The linear motor also includes a drag chain 36 and a distance sensor 37. The drag chain 36 is horizontally arranged on one side of the base 31 along the movement of the mover 33. The distance sensor 37 is arranged inside the base 31. The distance sensor 37 is used to feedback the position information of the mover 33. The distance sensor 37 can preferably be composed of a linear scale (not shown) or an infrared distance sensor 37. The principle of the linear scale is the same as that of the rotary encoder. Both are converted into photoelectric signals through the linear motion of the mover 33. The infrared distance sensor 37 can be as shown Figure 3As shown, the infrared ranging sensor 37 is irradiated toward the end face of the mover 33, and the current position information of the mover 33 is obtained by the distance measured by the infrared ranging sensor 37. By changing the start and stop position information of the mover 33, the movement range and length of the mover 33 can be adjusted.

[0021] Among them, the preferred embodiment 1 is as follows Figure 4 and Figure 5 As shown, the movable clamping arm 41 and the fixed clamping arm 42 are both composed of a "7"-shaped fixed arm 4a, and the clamping assembly 43 includes a first clamping block 51, a second clamping block 52 and a driving source 53. The first clamping block 51 is arranged at the bottom of the movable clamping arm 41 and the fixed clamping arm 42 so as to be movable up and down through the driving source 53. A second air avoidance groove 22 is provided in the middle of the working platform 2. The second air avoidance groove 22 is provided in a long strip structure along the moving direction of the driving platform 34. The second clamping block 52 passes through the second air avoidance groove 22 and is fixedly connected to the top surface of the driving platform 34. The first clamping block 51 can be located above the second clamping block 52 through the driving source 53 and move up and down.

[0022] Specifically, such as Figure 5 As shown, the driving source 53 is composed of a cylinder 7, which is vertically arranged inside the movable clamping arm 41 and the fixed clamping arm 42. The cylinder 7 includes a cylinder body 71, a driving shaft 72 and an air pipe interface 73. The driving shaft 72 can be movably arranged inside the cylinder body 71. The air pipe interface 73 is arranged at the top of the cylinder body 71 for connecting to an external air pipe. The bottom end of the driving shaft 72 can extend to the bottom of the movable clamping arm 41 and the fixed clamping arm 42 to be connected to the first clamping block 51.

[0023] Working process: The linear motor drives the driving platform 34 on the top surface to perform horizontal reciprocating motion along the groove direction of the first avoidance groove 21. When the movable clamping arm 41 moves away from the fixed clamping arm 42, the cylinder 7 of the fixed clamping arm 42 pushes the driving shaft 72 downward, so that the first clamping block 51 and the second clamping block 52 of the fixed clamping arm 42 approach each other to clamp one end of the material strip. At the same time, the cylinder 7 of the movable clamping arm 41 attracts the driving shaft 72 to move upward, so that the first clamping block 51 and the second clamping block 52 of the fixed clamping arm 42 are separated from each other. When the movable clamping arm 41 moves to the stop node, the driving source 53 of the movable clamping arm 41 and the fixed clamping arm 42 alternately completes the clamping and releasing actions. At this time, the movable clamping arm 41 can clamp the material and move to the side of the fixed clamping arm 42 to complete the feeding process.

[0024] Among them, the preferred embodiment 2 is as follows: Figure 6 and Figure 7As shown, the movable clamping arm 41 and the fixed clamping arm 42 are both composed of a gantry-type fixed arm 4b, and the clamping assembly 43 includes a first clamping block 51, a second clamping block 52 and a driving source 53. The first clamping block 51 is arranged at the bottom of the movable clamping arm 41 and the fixed clamping arm 42 so as to be movable up and down through the driving source 53. A second air avoidance groove 22 is provided in the middle of the working platform 2. The second air avoidance groove 22 is provided in a long strip structure along the moving direction of the driving platform 34. The second clamping block 52 passes through the second air avoidance groove 22 and is fixedly connected to the top surface of the driving platform 34. The first clamping block 51 can be located above the second clamping block 52 through the driving source 53 and move up and down.

[0025] Specifically, such as Figure 7 As shown, the driving source 53 is composed of a servo motor 6, a rotating shaft 61 and a telescopic shaft 63. The rotating shaft 61 is horizontally rotatably arranged inside the movable clamping arm 41 and the fixed clamping arm 42. The output end of the servo motor 6 is fixedly connected to one end of the rotating shaft 61. A fixed bracket 65 is provided between the rotating shaft 61 and the telescopic shaft 63. One end of the fixed bracket 65 is an air avoidance hole 651. The fixed bracket 65 is sleeved on the middle part of the rotating shaft 61 through the air avoidance hole 651. The other end of the fixed bracket 65 is bent 90 degrees and provided with a limiting hole 652. The telescopic shaft 63 is movably inserted into the inside of the limiting hole 652. A cam 62 is provided in the middle part of the rotating shaft 61. The top end of the telescopic shaft 63 is provided with a rotatable pulley 64. The telescopic shaft 63 slides against the edge of the cam 62 through the pulley 64. The bottom end of the telescopic shaft 63 can extend to the bottom of the movable clamping arm 41 and the fixed clamping arm 42 and be connected to the first clamping block 51.

[0026] Working process: The driving platform 34 on the top surface is driven by the linear motor to perform horizontal reciprocating motion along the groove direction of the first avoidance groove 21. When the movable clamping arm 41 moves away from the fixed clamping arm 42, the servo motor 6 at the end of the fixed clamping arm 42 rotates the rotating shaft 61, so that the cam 62 moves downward to just below, and the telescopic shaft 63 abuts against the cam 62 through the pulley 64 and moves downward, so that the first clamping block 51 and the second clamping block 52 of the fixed clamping arm 42 are close to each other to clamp one end of the material belt. At the same time, the servo motor 6 at the end of the movable clamping arm 41 rotates the rotating shaft 61, so that the cam 62 moves upward to just above, so that the first clamping block 51 and the second clamping block 52 of the fixed clamping arm 42 are separated from each other. When the movable clamping arm 41 moves to the stop node, the driving source 53 of the movable clamping arm 41 and the fixed clamping arm 42 alternately completes the clamping and releasing actions. At this time, the movable clamping arm 41 can clamp the material and move to the side of the fixed clamping arm 42 to complete the feeding process.

[0027] Among them, the preferred embodiment three is as follows Figure 8 and Figure 9As shown, the movable clamping arm 41 and the fixed clamping arm 42 are both composed of a gantry-type fixed arm 4b, and the clamping assembly 43 includes a first clamping block 51, a second clamping block 52 and a driving source 53. The first clamping block 51 is arranged at the bottom of the movable clamping arm 41 and the fixed clamping arm 42 so as to be movable up and down through the driving source 53. A second air avoidance groove 22 is provided in the middle of the working platform 2. The second air avoidance groove 22 is provided in a long strip structure along the moving direction of the driving platform 34. The second clamping block 52 passes through the second air avoidance groove 22 and is fixedly connected to the top surface of the driving platform 34. The first clamping block 51 can be located above the second clamping block 52 through the driving source 53 and move up and down.

[0028] Specifically, such as Figure 9 As shown, the driving source 53 is composed of an electromagnet 8, which is vertically arranged inside the movable clamping arm 41 and the fixed clamping arm 42. The electromagnet 8 includes a driving magnetic shaft 81, an excitation coil 82 and a guide rod 83. The top end of the driving magnetic shaft 81 is fixedly connected to the guide rod 83. The driving magnetic shaft 81 is movably connected to the inside of the movable clamping arm 41 and the fixed clamping arm 42 through the guide rod 83. The excitation coil 82 surrounds the outside of the driving magnetic shaft 81. The bottom end of the driving magnetic shaft 81 can extend to the bottom of the movable clamping arm 41 and the fixed clamping arm 42 to be connected to the first clamping block 51.

[0029] Working process: The linear motor drives the driving platform 34 on the top surface to perform horizontal reciprocating motion along the groove direction of the first avoidance groove 21. When the movable clamping arm 41 moves away from the fixed clamping arm 42, the electromagnet 8 of the fixed clamping arm 42 pushes the driving magnetic shaft 81 downward, so that the first clamping block 51 and the second clamping block 52 of the fixed clamping arm 42 approach each other to clamp one end of the material strip. At the same time, the electromagnet 8 of the movable clamping arm 41 is reset, and the driving magnetic shaft 81 moves upward, so that the first clamping block 51 and the second clamping block 52 of the fixed clamping arm 42 are separated from each other. When the movable clamping arm 41 moves to the stop node, the driving source 53 of the movable clamping arm 41 and the fixed clamping arm 42 alternately completes the clamping and releasing actions. At this time, the movable clamping arm 41 can clamp the material and move to the side of the fixed clamping arm 42 to complete the feeding process.

[0030] Among them, the preferred embodiment four is as follows Figure 10 and Figure 11 As shown, the movable clamping arm 41 and the fixed clamping arm 42 are both composed of a gantry-type fixed arm 4b, and the clamping assembly 43 includes two flexible clamping claws 9, which are horizontally arranged on both sides of the gantry-type fixed arm 4b. The two flexible clamping claws 9 are distributed in a horizontally symmetrical structure along the middle of the gantry-type fixed arm 4b.

[0031] Specifically, such as Figure 11As shown, the flexible clamping jaw 9 includes two upper and lower symmetrical clamping jaw portions 91, an oblique wedge push block 92 and a driving member 93. One end of the clamping jaw portion 91 extends toward the inner side of the gantry-type fixed arm 4b, and the other end of the clamping jaw portion 91 is provided with an inclined platform matching the oblique wedge push block 92. The clamping jaw portion 91 forms an oblique wedge sliding structure with the oblique wedge push block 92 through the inclined platform. The driving member 93 is movably connected to the oblique wedge push block 92. The driving member 93 is used to drive the oblique wedge push block 92 to move horizontally. The driving member 93 can preferably be composed of a cylinder 7 or a piezoelectric ceramic switch.

[0032] Working process: The linear motor drives the driving platform 34 on the top surface to perform horizontal reciprocating motion along the groove direction of the first avoidance groove 21. When the movable clamping arm 41 moves away from the fixed clamping arm 42, the flexible clamping claw 9 of the fixed clamping arm 42 moves outward through the oblique wedge push block 92, so that the two clamping claws 91 approach each other to clamp the two sides of the material strip. At the same time, the flexible clamping claw 9 of the movable clamping arm 41 moves inward through the oblique wedge push block 92, so that the two clamping claws 91 separate from each other to loosen the two sides of the material strip. When the movable clamping arm 41 moves to the stop node, the driving source 53 of the movable clamping arm 41 and the fixed clamping arm 42 alternately completes the clamping and releasing actions. At this time, the movable clamping arm 41 can clamp the material and move to the side of the fixed clamping arm 42 to complete the feeding process.
