Detailed implementation manners

[0033] The following further describes the present invention in conjunction with embodiments, but is not limited to the content in the specification.

[0034] As Figures 1 to 4 shown, the present invention discloses a first embodiment, providing a one-way transmission structure. The one-way transmission structure includes a moving base 10, a connecting rod 20 and a pushing plate 30. The moving base 10 is drivingly connected to a driving mechanism and reciprocates; the first end of the connecting rod 20 is pivotally connected to the moving base 10; the pushing plate 30 is fixedly connected to the second end of the connecting rod 20. The pushing plate 30 is rotatably arranged outside the moving base 10. The pushing plate 30 has a working end 31 and a counterweight end 32. The weight of the working end 31 is less than the weight of the counterweight end 32. The connection fulcrum of the second end of the connecting rod 20 and the pushing plate 30 is located between the working end 31 and the counterweight end 32; the pushing plate 30 has a first position state and a second position state. The pushing plate 30 switches between the first position state and the second position state during the reciprocating movement of the moving base 10; in the first position state of the pushing plate 30, the working end 31 is located above the counterweight end 32; in the second position state of the pushing plate 30, the working end 31 and the counterweight end 32 are at the same horizontal position; under the action of gravity, the pushing plate 30 switches from the second position state to the first position state.

[0035] The one-way transmission structure of the present invention is drivenly connected to the driving mechanism through the moving base 10, so that it can reciprocate. Since the pushing plate 30 is rotatably arranged on the moving base 10 through the connecting rod 20, the pushing plate 30 can switch between the first position state and the second position state during the reciprocating movement of the moving base 10. In the first position state, the working end 31 of the pushing plate 30 abuts against the pushed object for one-way pushing. In the second position state, the whole pushing plate 30 is in an avoidance state, avoiding the pushed object during the reciprocating movement, and then completing sliding and resetting in the reverse direction.

[0036] One end of the pushing plate 30 is the working end 31, and the other end is the counterweight end 32. The weight of the working end 31 is less than that of the counterweight end 32, and the connection fulcrum of the second end of the connecting rod 20 and the pushing plate 30 is located between the working end 31 and the counterweight end 32. When there is no external force on the pushing plate 30, the counterweight end 32 descends under the action of gravity, driving the whole pushing plate 30 to form a vertical state, that is, switching from the second position state to the first position state, thus replacing the spring reset, making its structure simpler and the installation and maintenance more convenient.

[0037] In the above embodiment, the one-way transmission structure further includes a rotating shaft 40, and the rotating shaft 40 is rotatably arranged in the moving base 10; the first end of the connecting rod 20 is connected to the rotating shaft 40. By adopting the rotating shaft 40 and the connecting rod 20 in the one-way transmission structure of the present invention, the pushing plate 30 is connected to the rotating shaft 40 through the connecting rod 20 and is rotatably arranged on the moving base 10 through the rotating shaft 40, which can make the rotation process more stable.

[0038] In the above embodiment, an inclined surface 33 is provided on the pushing plate 30, and the inclined surface 33 is located from the connection fulcrum of the second end of the connecting rod 20 and the pushing plate 30 to the working end 31. In the direction from the connection fulcrum of the second end of the connecting rod 20 and the pushing plate 30 to the working end 31, the thickness of the pushing plate 30 in the area of the inclined surface 33 gradually decreases. By providing the inclined surface 33 on the pushing plate 30 in the one-way transmission structure of the present invention, the inclined surface 33 can extend from the working end 31 of the pushing plate 30 to the counterweight end 32, and the thickness of the pushing plate 30 also gradually becomes thicker from the working end 31 to the counterweight end 32 accordingly. There are two advantages: First, setting the inclined surface 33 can play a buffering role when the pushing plate 30 contacts other components during operation. Second, after setting it as an inclined surface 33, the weight of the working end 31 can be reduced as much as possible, so that the weight difference between the working end 31 and the counterweight end 32 is larger, making it easier to reset, and the overall length of the pushing plate 30 can be reduced to achieve miniaturization. Of course, in this embodiment, the inclined surface 33 only extends from the working end 31 to the fulcrum position where the second end of the connecting rod 20 is connected to the pushing plate 30. In this way, the counterweight end 32 is still a normal plate-like structure, and its weight is much greater than that of the working end 31, so that the volume of the counterweight end 32 can be reduced, effectively shortening the overall length of the pushing plate 30.

[0039] In the above embodiment, the moving base 10 includes a sleeve 11, and the first end of the connecting rod 20 is pivotally connected inside the sleeve 11; the pushing plate 30 is located outside the sleeve 11. A limiting chute 111 is provided on the outer peripheral wall of the sleeve 11, and the connecting rod 20 is arranged in the limiting chute 111. By providing the limiting chute 111, the one-way transmission structure of the present invention enables the connecting rod 20 to be arranged in the limiting chute 111. When the pushing plate 30 rotates, the connecting rod 20 moves in the limiting chute 111.

[0040] In the above embodiment, both ends of the limiting chute 111 are arc-shaped structures matching the surface of the connecting rod 20. By making both ends of the limiting chute 111 be arc-shaped structures matching the surface of the connecting rod 20, when the connecting rod 20 contacts both ends of the limiting chute 111, it can be maximally matched in the arc-shaped structure, thereby increasing the contact area, reducing the contact pressure between the connecting rod 20 and the limiting chute 111, reducing wear, and ensuring the service life of both.

[0041] In the above embodiment, the limiting chute 111 has a first limiting end 111a and a second limiting end 111b arranged oppositely; when the pushing plate 30 is in the first position state, the connecting rod 20 is in a horizontal state and is in limiting cooperation with the second limiting end 111b; when the pushing plate 30 is in the second position state, the connecting rod 20 is in a vertical state and is in limiting cooperation with the first limiting end 111a. By providing the first limiting end 111a and the second limiting end 111b, the one-way transmission structure of the present invention enables the connecting rod 20 to achieve limiting cooperation with the limiting chute 111.

[0042] As Figures 1 to 3 shown in the embodiment, the one-way transmission structure further includes a rotating shaft 40 and a ball bearing 50. The rotating shaft 40 is rotatably arranged inside the sleeve 11; the first end of the connecting rod 20 is connected to the rotating shaft 40; the ball bearing 50 is arranged inside the sleeve 11, and the rotating shaft 40 is installed on the ball bearing 50. By providing the rotating shaft 40 and the ball bearing 50, the one-way transmission structure of the present invention enables the rotating shaft 40 to be rotatably arranged in the sleeve 11 through the ball bearing 50. By using the ball bearing 50, the rotating shaft 40 has small friction, low noise, and a stable rotation process during rotation.

[0043] In the above embodiment, the moving base 10 further includes a connecting frame 12. The sleeve 11 is fixedly connected to the connecting frame 12, and the connecting frame 12 is directly driven and connected to the driving mechanism. An arc-shaped groove 121 matching the outer surface of the sleeve 11 is provided on the connecting frame 12, and the sleeve 11 is fixedly connected in the arc-shaped groove 121. By providing the arc-shaped groove 121 matching the outer surface of the sleeve 11 on the connecting frame 12, the one-way transmission structure of the present invention makes the installation of the sleeve 11 more fitting and firm, ensuring its firmness.

[0044] As shown Figures 5 to 7 According to the second embodiment of the present invention, a conveying device is provided, including the above-mentioned one-way transmission structure.

[0045] In the above embodiment, the conveying device further includes a guide rail 60 and a driving mechanism. A process plate 70 is placed on the guide rail 60, and the process plate 70 is movable along the guide rail 60; the driving mechanism drives the process plate 70 to move in a single direction through the one-way transmission structure. By setting the one-way transmission structure in the conveying device of the present invention, the process plate 70 can be moved in a single direction, and at the same time, the structure is simpler, which is convenient for installation and maintenance.

[0046] In the above embodiment, in the first position state of the push plate 30, the working end 31 abuts against the first end of the process plate 70, and the push plate 30 can push the process plate 70 to move; in the second position state of the push plate 30, the position of the push plate 30 is in an overall avoidance of the process plate 70. In the conveying device of the present invention, while the working end 31 of the push plate 30 abuts against the first end of the process plate 70, the process plate 70 is pushed to move. When the push plate 30 is in the second position state, the push plate 30 is entirely below the process plate 70, so as to avoid the process plate 70. Until the push plate 30 leaves the second end of the process plate 70, it switches to the first position state under the action of gravity and continues to push the process plate 70.

[0047] In the above embodiment, the number of the process plates 70 is multiple, and the multiple process plates 70 are arranged at intervals along the guide rail 60; a contact surface 71 for cooperating with the working end 31 is formed at the first ends of all the process plates 70, and an arc chamfer 72 for contacting the push plate 30 is formed at the second ends of all the process plates 70. In the conveying device of the present invention, while the working end 31 of the push plate 30 abuts against the first end of the process plate 70, the process plate 70 is pushed to move a certain distance and then returns. During the return process, when it encounters the next process plate 70, under the abutment of the second end of the next process plate 70, the push plate 30 enters the second position state, making the push plate 30 entirely below the next process plate 70, so as to avoid the next process plate 70. Until the push plate 30 leaves the first end of the next process plate 70, it switches to the first position state under the action of gravity and continues to push the process plate 70. By forming an arc chamfer 72 for contacting the push plate 30 at the second end of the process plate 70, the impact during the pushing process can be reduced, the service life can be improved, especially in cooperation with the inclined surface 33 of the working end 31, it is smoother and more fluent.

[0048] In the above embodiments, the driving mechanism includes a feeding mechanism 80 and a cylinder 90. The feeding mechanism 80 is drivingly connected to the process plate 70. The telescopic rod of the cylinder 90 is connected to the feeding mechanism 80, and the telescopic rod of the cylinder 90 drives the feeding mechanism 80 to move through telescoping. The feeding mechanism 80 includes a driving rod 81 and a one-way transmission structure. The telescopic rod of the cylinder 90 is connected to the driving rod 81. The moving base 10 of the one-way transmission structure is fixedly connected to the driving rod 81. When the telescopic rod of the cylinder 90 reciprocates, it drives the driving rod 81 to reciprocate. During the reciprocating movement of the driving rod 81, the one-way transmission structure pushes the process plate 70 to move unidirectionally in a single direction. The one-way transmission structure of the present invention fixedly connects the moving base 10 of the one-way transmission structure to the driving rod 81, so that when the telescopic rod of the cylinder 90 reciprocates, it drives the driving rod 81 to reciprocate, and during the reciprocating movement of the driving rod 81, the one-way transmission structure pushes the process plate 70 to move unidirectionally in a single direction.

[0049] In the above embodiments, the feeding mechanism 80 further includes a driving rod 82. The driving rod 82 is fixedly connected to the driving rod 81. The driving rod 82 is arranged along the extension direction of the guide rail 60. A plurality of one-way transmission structures are arranged at intervals along the extension direction of the driving rod 82. There are a plurality of process plates 70, and the process plates 70 correspond to the one-way transmission structures one by one. During the reciprocating movement of the driving rod 81, each one-way transmission structure pushes the corresponding process plate 70 to move unidirectionally in a single direction. The conveying device of the present invention can make each one-way transmission structure correspondingly push a process plate 70 through a plurality of one-way transmission structures, thereby greatly improving the transmission efficiency.

[0050] According to the third aspect of the present invention, a production line is disclosed, including the above-mentioned conveying device.

[0051] Obviously, the above embodiments of the present invention are merely examples for clearly explaining the present invention, rather than limitations on the embodiments of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the embodiments here.
