It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation to the present utility model. In addition, the terms "first", "second", and "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0040] In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0041] Such as Figure 1 and Figure 2 and Figure 3As shown in the figure, it includes a driving component 1, a clamping component 2 and a steering component 3. The driving component 1 includes a bracket 11, a linear module 12 and a sliding seat 13. The linear module 12 is arranged on the bracket 11, and the sliding seat 13 is slidably arranged on the driving end of the linear module 12. The sliding seat 13 slides on the bottom of the linear module 12.

[0042] The clamping component 2 includes a first cylinder 21 and a second cylinder 22. The first cylinder 21 is connected to the sliding seat 13. The linear module 12 drives the sliding seat 13 to move, and the sliding seat 13 drives the first cylinder 21 to move. The second cylinder 22 is connected to the driving end of the first cylinder 21, and the first cylinder 21 drives the second cylinder 22 to rise or fall.

[0043] The second cylinder 22 has a first driving end and a second driving end. A first slider 221 is arranged on the first driving end of the second cylinder 22, and a second slider 222 is arranged on the second driving end of the second cylinder 22. The first slider 221 and the second slider 222 have two states of approaching and separating from each other. The second cylinder 22 drives the first slider 221 and the second slider 222 to move, and the first slider 221 and the second slider 222 can approach or separate from each other.

[0044] The clamping component 2 further includes a first jaw 23 and a second jaw 24. The first jaw 23 is arranged on the first slider 221, and the second jaw 24 is arranged on the second slider 222. When the first jaw 23 and the second jaw 24 approach each other, the first jaw 23 and the second jaw 24 are used to jointly clamp the workpiece. When the first jaw 23 and the second jaw 24 separate from each other, the first jaw 23 and the second jaw 24 release the workpiece.

[0045] The steering component 3 includes a motor 31 and a material supporting plate 32. The material supporting plate 32 is connected to the driving end of the motor 31. The motor 31 is vertically arranged, and the material supporting plate 32 is located above the motor 31. The motor 31 drives the material supporting plate 32 to rotate, and the material supporting plate 32 is used to support the workpiece.

[0046] A feeding component 5 is further arranged at the bottom of the bracket 11. The feeding component 5 includes a feeding module 51 and a sliding mechanism 52. The feeding module 51 drives the sliding mechanism 52 to move. The sliding mechanism 52 includes a supporting plate 53. The supporting plate 53 is located at the top of the sliding mechanism 52, and the sliding mechanism 52 can move into the clamping area of the first clamping block 231 and the second clamping block 232.

[0047] Furthermore, multiple feeding components 5 can be arranged in parallel, and the first clamping block 231 and the second clamping block 232 can achieve multi-station clamping of the workpiece.

[0048] Such as Figure 4 and Figure 5As shown, the clamping assembly 2 further includes a connecting plate 25 and a bottom plate 26. The connecting plate 25 is connected to the sliding seat 13 and also to the side wall of the first cylinder 21. The connecting plate 25 makes the connection between the first cylinder 21 and the sliding seat 13 more stable. The upper surface of the bottom plate 26 is connected to the driving end of the first cylinder 21, and the second cylinder 22 is connected to the lower surface of the bottom plate 26. The first cylinder 21 and the second cylinder 22 are respectively located on both sides of the bottom plate 26. The bottom plate 26 has a large force-bearing area. When the bottom plate 26 is driven by the first cylinder 21, the bottom plate 26 moves more stably. At the same time, the large fixed area between the second cylinder 22 and the bottom plate 26 can also make the second cylinder 22 fixed more stably.

[0049] On both sides of the first jaw 23, a first clamping block 231 and a second clamping block 232 are respectively arranged. On both sides of the second jaw 24, a third clamping block 243 and a fourth clamping block 244 are respectively arranged. A guiding column 234 is arranged on the first clamping block 231 and the third clamping block 243. When the first jaw 23 and the second jaw 24 approach or move away from each other, the first clamping block 231 and the third clamping block 243 move on the guiding column 234 to ensure that the first jaw 23 and the second jaw 24 move on the same straight line.

[0050] A first limiting column 241 is arranged on the second clamping block 232, and a second limiting column 242 is arranged on the fourth clamping block 244. The first limiting column 241 and the second limiting column 242 are arranged opposite to each other. Both the first limiting column 241 and the second limiting column 242 have a small amount of elasticity. When the first jaw 23 and the second jaw 24 are set at a close distance to each other, the first limiting column 241 and the second limiting column 242 are in contact with each other to prevent the first jaw 23 and the second jaw 24 from approaching too closely.

[0051] As Figure 6 and Figure 7 As shown, a plurality of limiting blocks 30 are arranged on the material supporting plate 32. The plurality of limiting blocks 30 are distributed on the outer periphery of the first placing area 321 and the second placing area 322. In this way, no matter whether the workpiece is in the first placing area 321 or the second placing area 322, the plurality of limiting blocks 30 can play a role in fixing the workpiece to prevent the position of the workpiece on the first placing area 321 or the second placing area 322 from changing when the material supporting plate 32 rotates. The sizes of the first placing area 321 and the second placing area 322 are set according to the size of the workpiece.

[0052] The limiting block 30 has a first limiting surface 331 and a second limiting surface 332. The first limiting surface 331 and the second limiting surface 332 are perpendicularly arranged. In this way, the corners on the outer periphery of the workpiece are clamped between the first limiting surface 331 and the second limiting surface 332. The first limiting surface 331 and the second limiting surface 332 are located on the outer periphery of the first placing area 321 and the second placing area 322, and the first placing area 321 and the second placing area 322 are spaced apart by a set distance.

[0053] The limiting block 30 is further provided with a first guiding surface 333 and a second guiding surface 334. The first guiding surface 333 is located at the top end of the first limiting surface 331, and the second guiding surface 334 is located at the top end of the second limiting surface 332. An included angle is formed between the first guiding surface 333 and the second guiding surface 334. Both the first guiding surface 333 and the second guiding surface 334 are inclined. Both the first guiding surface 333 and the second guiding surface 334 are inclined towards the outer periphery of the material supporting tray 32. In this way, when the workpiece falls, if the edge of the workpiece first contacts the first guiding surface 333, the workpiece slides from the first guiding surface 333 to the first limiting surface 331, and then falls from the first limiting surface 331 onto the first placement area 321 or the second placement area 322. If the workpiece first contacts the second guiding surface 334, then the workpiece slides from the second guiding surface 334 to the second limiting surface 332, and then falls from the second limiting surface 332 onto the first placement area 321 or the second placement area 322.

[0054] The steering assembly 3 further includes a support block 33, a runner 34, a hollow ring 35 and a base 36. The motor 31 is arranged on the base 36. The hollow ring 35 is connected to the bottom surface of the material supporting tray 32. The space of the hollow ring 35 is hollowed out. The driving end of the motor 31 passes through the hollow ring 35. A plurality of support blocks 33 are evenly arranged on the base 36, and the motor 31 is located in the middle of the plurality of support blocks 33. The runner 34 is rotatably arranged on the support block 33. The hollow ring 35 is rotatably lapped on the plurality of runners 34. When the motor 31 drives the material supporting tray 32 to rotate, the hollow ring 35 rotates on the plurality of runners 34. The hollow ring 35 is in rolling contact with the runners 34, and the hollow ring 35 drives the runners 34 to rotate.

[0055] The steering assembly 3 further includes a steering cylinder 37. A positioning rod 38 is arranged at the driving end of the steering cylinder 37. A first positioning hole 323 and a second positioning hole 324 are respectively arranged on both sides of the material supporting tray 32. The first positioning hole 323 and the second positioning hole 324 stay in the moving path of the positioning rod 38 in a rotating manner in sequence. When the motor 31 drives the material supporting tray 32 to rotate 180°, either the first positioning hole 323 or the second positioning hole 324 stays in the moving path of the positioning rod 38. At this time, the steering cylinder 37 drives the positioning rod 38 to rise, and the positioning rod 38 is sleeved in the first positioning hole 323 or the second positioning hole 324, so that the positioning of the material supporting tray 32 can be realized.

[0056] A limiting seat 361 is provided on the base 36. A limiting rod 362 and an elastic member 363 are provided on the limiting seat 361. The elastic member 363 is located above the limiting rod 362. The length of the elastic member 363 is longer than that of the limiting rod 362. A limiting strip 320 is provided on the material supporting tray 32. Both the limiting rod 362 and the elastic member 363 are located on the rotation path of the limiting strip 320. When the material supporting tray 32 rotates, the limiting strip 320 first abuts against the elastic member 363, and the elastic member 363 slightly contracts to slow down the rotation of the material supporting tray 32. Then the limiting strip 320 abuts against the limiting rod 362. The elastic member 363 can be a spring.

[0057] Further, a pair of limiting seats 361, as well as the limiting rods 362 and the elastic members 363, are symmetrically arranged on both sides of the base 36, ensuring that the material supporting tray 32 has a buffering effect and a limiting effect in both directions when rotating back and forth.

[0058] A housing 4 is provided in cooperation with the steering assembly 3. The housing 4 wraps around the outer periphery of the steering assembly 3, which can prevent the material supporting tray 32 from colliding with other objects when rotating.

[0059] As Figure 8 and Figure 9 shown, the material supporting tray 32 is divided into a first placement area 321 and a second placement area 322. The first placement area 321 and the second placement area 322 stay in the placement areas of the first jaw 23 and the second jaw 24 in a rotating manner in sequence. The first jaw 23 and the second jaw 24 jointly place the workpiece on the material supporting tray 32.

[0060] If the first placement area 321 is located in the placement area of the first jaw 23 and the second jaw 24, driven by the linear module 12, the first jaw 23 and the second jaw 24 jointly clamp the workpiece and move it above the first placement area 321. Then, driven by the first cylinder 21, the first jaw 23 and the second jaw 24 jointly clamp the workpiece and descend to the set height. Finally, driven by the second cylinder 22, the first jaw 23 and the second jaw 24 move away from each other, and the workpiece falls onto the first placement area 321. Then the first jaw 23 and the second jaw 24 jointly reset and then grab the workpiece again. The second cylinder 22 indirectly drives the first jaw 23 and the second jaw 24 to clamp the workpiece to be transported. The first cylinder 21 drives the second cylinder 22 to rise to the set height, and the linear module 12 indirectly drives the first jaw 23 and the second jaw 24 to move above the material supporting tray 32.

[0061] After placing a set number of workpieces on the first placement area 321, the motor 31 drives the material supporting tray 32 to rotate by a set angle. In this application, the motor 31 drives the material supporting tray 32 to rotate 180° each time. The material supporting tray 32 rotates back and forth and does not always rotate in one direction.

[0062] Then, the second placement area 322 can rotate to the placement area of the first jaw 23 and the second jaw 24, and the workpiece in the previous first placement area 321 has been turned to enter the next process step.

[0063] The above embodiments are only used to illustrate the technical concept and features of the present invention. The purpose is to enable those skilled in the art to understand the content of the present invention and implement it accordingly. It is not intended to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
