[0018] In order to make the above objects, features, and advantages of the present utility model more obvious and understandable, the following will describe in detail the specific embodiments of the present utility model with reference to the accompanying drawings.

[0019] As Figures 1 - 3 shown, the embodiment of the present application provides a 90-degree flipping and picking mechanism, including a jacking cylinder 1, an L-shaped fixing plate 2, a guiding mechanism 3, a claw mechanism 4, and a spring 5. The jacking cylinder 1 is installed at the bottom of the L-shaped fixing plate 2, the guiding mechanism 3 is installed on the L-shaped fixing plate 2, and the driving end of the jacking cylinder 1 passes through the L-shaped fixing plate 2 and is hinged to the bottom of the claw mechanism 4 through a first rotating assembly 6. The guiding mechanism 3 is symmetrically provided with two L-shaped sliding grooves 31, and both ends of the first rotating assembly 6 are slidably matched with the two L-shaped sliding grooves 31 respectively. The bottom of the claw mechanism 4 is slidably connected to the two L-shaped sliding grooves 31 of the guiding mechanism 3 through a second rotating assembly 7. The second rotating assembly 7 is located on one side of the first rotating assembly 6. One end of the spring 5 is connected to the upper half of the claw mechanism 4 through a first pin shaft 51, and the other end of the spring 5 is connected to the side end of the L-shaped fixing plate 2 through a second pin shaft 52.

[0020] Specifically, the jacking cylinder 1 is installed at the bottom end of the L-shaped fixing plate 2, the guiding mechanism 3 is installed on the L-shaped fixing plate 2, and both ends of the guiding mechanism 3 are fixedly connected to the two end faces of the L-shaped fixing plate 2 respectively. The bottom of the claw mechanism 4 is slidably connected to the two L-shaped sliding grooves 31 of the guiding mechanism 3 through a first rotating assembly 6 and a second rotating assembly 7 respectively. The driving end of the jacking cylinder 1 passes through the fixing plate and is hinged to the rotating shaft of the first rotating assembly 6. Both ends of the spring 5 are connected to the upper half of the claw mechanism 4 and the top side end of the fixing plate through a first pin shaft 51 and a second pin shaft 52 respectively. Among them, the L-shaped sliding groove 31 includes a horizontal sliding groove and a vertical sliding groove. When the claw mechanism 4 is in the initial vertical clamping state, the first rotating assembly 6 is located at the intersection of the horizontal sliding groove and the vertical sliding groove, and the second rotating assembly 7 is located at the top end of the horizontal sliding groove. When the claw mechanism 4 rotates to the 90-degree flipping state, the first rotating assembly 6 is located at the bottom of the vertical sliding groove, and the second rotating assembly 7 is located at the intersection of the horizontal sliding groove and the vertical sliding groove.

[0021] During operation, the jaw cylinder 42 of the jaw mechanism 4 grips the workpiece, and then the lifting cylinder 1 drives the first rotating assembly 6 of the L-shaped connecting plate 41 of the jaw mechanism 4 to move downward along the vertical chute of the L-shaped chute 31, thereby driving the second rotating assembly 7 of the L-shaped connecting plate 41 of the jaw mechanism 4 to move along the horizontal chute of the L-shaped chute 31, so that the jaw cylinder 42 drives the workpiece to perform a 90-degree flip. After other mechanisms in the prior art grip the workpiece, the jaw cylinder 42 of the jaw mechanism 4 releases the workpiece. Then the lifting cylinder 1 drives the first rotating assembly 6 of the L-shaped connecting plate 41 of the jaw mechanism 4 to move upward along the vertical chute of the L-shaped chute 31. At the same time, under the action of the pulling force of the spring 5, the jaw mechanism 4 returns to its initial position. This process is repeated to flip and convey the workpiece in sequence.

[0022] In the above structure, the linear motion of the lifting cylinder 1 drives the jaw mechanism 4 to perform a curvilinear motion along the guiding mechanism 3, realizing the displacement and 90-degree flip of the workpiece. The spring 5 exerts a certain pulling force on the flipped jaw mechanism 4, which can avoid jamming during the rotation of the jaw mechanism 4 and ensure the smoothness of the rotation of the jaw mechanism 4. This 90-degree flip and pick-up mechanism not only has a simple structure and strong applicability, but also is convenient to operate, which is beneficial to later maintenance and repair. At the same time, it has a compact structure and is convenient to use in a narrow space.

[0023] As Figure 1 and Figure 2 shown, in one embodiment, the guiding mechanism 3 of the 90-degree flip and pick-up mechanism includes two symmetrically arranged L-shaped guiding side plates 32. Two connecting blocks 33 are symmetrically arranged between the two guiding side plates. A gap is provided between the two connecting blocks 33 for the driving end of the lifting cylinder 1 to pass through. The two L-shaped chutes 31 are respectively symmetrically arranged on the two L-shaped guiding side plates 32.

[0024] Specifically, one end of the two symmetrically arranged L-shaped guiding side plates 32 is respectively fixedly connected to the vertical end of the fixing plate, and the other end of the two L-shaped guiding side plates 32 is respectively fixedly connected to the horizontal end of the fixing plate. L-shaped chutes 31 are respectively arranged on the two L-shaped guiding side plates 32. The first rotating assembly 6 and the second rotating assembly 7 of the L-shaped connecting plate 41 of the jaw mechanism 4 are respectively slidably connected to the L-shaped chutes 31 of the two L-shaped guiding side plates 32, and the bottom of the L-shaped connecting plate 41 is located between the two L-shaped guiding side plates 32. The driving end of the lifting cylinder 1 passes through the fixing plate and is hinged to the first rotating shaft 61 of the first rotating assembly 6. The driving end of the lifting cylinder 1 is located between the two L-shaped guiding side plates and the two connecting blocks 33.

[0025] The guiding mechanism 3 arranged in this way has a compact structure and a small volume, which is convenient to convert the linear motion of the lifting mechanism into the curvilinear motion of the jaw mechanism 4 to realize the 90-degree flip of the workpiece.

[0026] AsFigure 1 and Figure 2 As shown in Figure 2 , in one embodiment, the gripper mechanism 4 of the 90-degree flipping and picking mechanism includes an L-shaped connecting plate 41 and a gripper cylinder 42. The gripper cylinder 42 is installed at the top side end of the L-shaped connecting plate 41, and the bottom of the L-shaped connecting plate 41 is slidably connected to two L-shaped sliding grooves 31 through a first rotating assembly 6 and a second rotating assembly 7.

[0027] Specifically, the gripper cylinder 42 is installed at the vertically arranged side end of the L-shaped connecting plate 41. A fixed block is provided at the side end of the L-shaped connecting plate 41 away from the gripper cylinder 42, and a first pin shaft 51 is fixedly provided on the fixed block. The hook at one end of the spring 5 is hung on the first pin shaft 51. The horizontally arranged bottom of the L-shaped connecting plate 41 is respectively connected to the first rotating assembly 6 and the second rotating assembly 7. The gripper cylinder 42 is located above the guiding mechanism 3, and the gripper end of the gripper cylinder 42 is vertically upward.

[0028] The gripper cylinder 42 arranged in this way has a simple structure and a small volume, which is convenient for clamping workpieces.

[0029] As Figure 2 shown in Figure 2 , in one embodiment, the first rotating assembly 6 of the 90-degree flipping and picking mechanism includes a first rotating shaft 61 and two first cam wheels 62. The first rotating shaft 61 is respectively connected to the L-shaped connecting plate 41 and the driving end of the lifting cylinder 1. The two first cam wheels 62 are respectively installed at both ends of the first rotating shaft 61, and the two first cam wheels 62 are respectively slidably matched with the two L-shaped sliding grooves 31.

[0030] Specifically, the first rotating shaft 61 sequentially passes through the side end of the L-shaped connecting plate 41, the driving end of the lifting cylinder 1 and the other side end of the L-shaped connecting plate 41, and both ends of the first rotating shaft 61 are respectively connected to the two first cam wheels 62. The two first cam wheels 62 are slidably matched with the two L-shaped sliding grooves 31 of the guiding mechanism 3. The lifting cylinder 1 drives the first rotating shaft 61 to move downward, the first rotating shaft 61 drives the L-shaped connecting plate 41 and the two first cam wheels 62 to move, and the two first cam wheels 62 move along the vertical sliding grooves of the two L-shaped sliding grooves 31.

[0031] This setting facilitates the lifting mechanism to drive the L-shaped connecting plate 41 to drive the gripper cylinder 42 to move.

[0032] As Figure 2 shown in Figure 2 , in one embodiment, the second rotating assembly 7 of the 90-degree flipping and picking mechanism includes two second cam wheels 71. The two second cam wheels 71 are respectively installed at the two side ends of the bottom of the L-shaped connecting plate 41, and the two second cam wheels 71 are respectively slidably matched with the two L-shaped sliding grooves 31.

[0033] Specifically, two second cams 71 are respectively installed at the bottom side ends of the L-shaped connecting plate 41. When the lifting cylinder 1 drives the first rotating assembly 6 to move, the two second cams 71 move along the horizontal chutes of the two L-shaped chutes 31. This setting facilitates the control of the rotation direction of the jaw mechanism 4.

[0034] As Figure 1 and Figure 3 shown, in one embodiment, a first limiting assembly 8 for limiting the jaw mechanism 4 in the flipped state is provided on the fixing plate of the 90-degree flipping and picking mechanism. The first limiting assembly 8 includes a first buffer 81 and a first screw 82. The first buffer 81 performs soft limiting on the flipped jaw mechanism 4, and the first screw 82 performs hard limiting on the jaw mechanism 4 of the rotation axis, which can effectively prevent the jaw mechanism 4 from flipping excessively.

[0035] As Figure 1 shown, in one embodiment, a second limiting assembly 9 for limiting the jaw mechanism 4 in the vertical state is provided at the side end of the fixing plate of the 90-degree flipping and picking mechanism close to the spring 5. The second limiting assembly 9 includes a second buffer 91 and a second screw 92. The second buffer 91 performs soft limiting on the jaw mechanism 4 in the initial vertical direction, and the second screw 92 performs hard limiting on the jaw mechanism 4 in the initial vertical direction, which can effectively prevent the jaw mechanism 4 from resetting excessively.

[0036] The above embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
