Description

Technical Field

[0001] The utility model relates to a silkworm foil clamping structure, in particular to a silkworm foil clamping arm. Background Art

[0002] my country has a long history of silk culture and silkworm breeding. At present, silkworm breeding is still mainly operated by manual operation, supplemented by mechanical operation, which is difficult to adapt to the development of modern agriculture. It is urgent to improve the mechanization and automation level of silkworm breeding. At the same time, silkworm breeding is showing a trend of large-scale operation, which requires equipment with a higher degree of mechanization and automation, changing the labor-intensive production mode, reducing labor intensity, improving production and management efficiency, realizing industrial transformation and upgrading, and promoting high-quality development of the industry.

[0003] A fully automatic silkworm raising robot system for mulberry feeding CN2023118298372 and a fully automatic silkworm raising machine CN2021223431549 use a six-axis manipulator to stack silkworm foil. The six-axis manipulator has six degrees of freedom, but the silkworm foil stacking operation does not require so many degrees of freedom, so a two-degree-of-freedom special stacking device is more suitable for silkworm raising and stacking silkworm foil; at the same time, the stacked silkworm foil needs to be manually transferred, specifically, the piles of silkworm foil to be raised need to be manually transferred to the equipment station, and the piles of silkworm foil that have been raised need to be manually transferred from the equipment station to the silkworm room; in addition, both patents are for mulberry leaf silkworm raising, and do not involve feed silkworm raising.

[0004] Silkworm feeding and transmission platform CN2019201033689, this patent is an early application of the inventor, which proposes horizontal conveying of silkworm foil and silkworm feeding operation during the movement of silkworm foil. This equipment requires manual silkworm foil stacking operation, and the degree of automation is low.

[0005] Silkworm foil is a tool for raising silkworms. After long-term use, the foil will be deformed, resulting in an irregular shape, making it difficult for the robot to use the deformed foil. In addition, in order to control costs, the accuracy requirements for the clamping robot that clamps the foil are not too high, which leads to low accuracy of the clamping robot during movement. As a result, when clamping the foil, some of the foil cannot enter the clamping groove of the clamping arm, which makes the clamping robot unable to clamp the foil stably and effectively. In severe cases, the foil may be squeezed and damaged. Utility Model Content

[0024] like Figure 1 As shown, a silkworm foil clamping arm includes a support arm 102, on which a linear guide mechanism is installed, the execution end of the linear guide mechanism is connected to a lifting arm 103, and the execution end of the linear guide mechanism is in a downstroke under the action of gravity of the lifting arm 103, and clamping mechanisms are installed at both ends of the lifting arm 103, and the clamping mechanism has a clamping groove, and the entrance of the clamping groove is a bell mouth, through which the clamping mechanism can use silkworm foils of different sizes, especially after the silkworm foil has been used for a period of time and is deformed, it can still enter the clamping groove through the bell mouth and be clamped by the clamping mechanism.

[0025] In this embodiment, if Figure 1 As shown, the clamping mechanism includes a guide piece 108 and a lifting piece 107, both of which are mounted on the lifting arm 103, the guide piece 108 is located above the lifting piece 107, and a clamping groove is formed between the guide piece 108 and the lifting piece 107, an end of the guide piece 108 away from the lifting arm 103 is provided with a first guide slope 109 inclined upward, and an end of the lifting piece 107 away from the lifting arm 103 is provided with a second guide slope 110 inclined downward, the first guide slope 109 and the second guide slope 110 form a bell mouth, and the clamping mechanism clamps the silkworm foil. When the second guide slope 110 is inserted into the bottom of the silkworm foil, the silkworm foil enters the clamping groove under the guidance of the second guide slope 110, and is then clamped by the clamping groove. When the clamping mechanism clamps the silkworm foil, the silkworm foil is deformed, resulting in irregularity. If the first guide slope 109 contacts the silkworm foil, as the clamping mechanism gradually moves closer to the silkworm foil, the silkworm foil applies an upward thrust to the lifting arm 103 through the first guide slope 109, thereby making the linear guide mechanism move upward, thereby making the clamping mechanism move upward, and then making the clamping groove able to align with the silkworm foil, and finally clamping the silkworm foil.

[0026] In this embodiment, if Figure 1As shown, there are two support arms 102, and the ends of the two support arms 102 close to the linear guide mechanism are connected by a connecting rod 106, and the ends of the two support arms 102 away from the linear guide mechanism are connected by a mounting plate 101. The support arms 102 are cantilevers. After the two support arms 102 are connected by the connecting rod 106 and the mounting plate 101, the structural strength of the support arms 102 can be increased, thereby increasing the carrying capacity of the silkworm foil clamping arm.

[0027] In this embodiment, if Figure 1 As shown, the lifting piece 107 includes an installation section, a vertical section and a horizontal support platform 111. The installation section, the vertical section and the support platform 111 are distributed in a Z shape, and the second guide slope 110 is connected to the support platform 111. To facilitate the processing and installation of the clamping mechanism, the lifting piece 107 is located on one side of the guide piece 108, and the lifting piece 107 and the guide piece 108 are both connected to the support arm 102 through locking screws. Therefore, the lifting piece 107 and the guide piece 108 can be made separately. When the lifting piece 107 and the guide piece 108 are both installed on the support arm 102, on the axial projection plane, a clamping groove is formed between the straight end of the guide piece 108 and the support platform 111, and a bell mouth is formed between the first guide slope 109 and the second guide slope 110.

[0028] In this embodiment, if Figure 1 As shown, the linear guide mechanism includes a linear bearing 104 and a guide rod 105. The linear bearing 104 is installed on the support arm 102, and the guide rod 105 is slidably installed in the linear bearing 104. A limiting cap 112 is provided on the top of the guide rod 105 to prevent the guide rod 105 from falling out of the linear bearing 104. The bottom of the guide rod 105 is connected to the lifting arm 103. Furthermore, the limiting cap 112 is a sheet-mounted structure, and the limiting cap 112 is installed on the top of the guide rod 105 by a locking screw. In the initial state, the guide rod 105 is in a downstroke under the gravity of the lifting arm 103, that is, the limiting cap 112 abuts against the top of the linear bearing 104, and when the guide rod 105 is subjected to an axial upward force, the guide rod 105 moves upward along the linear bearing 104.

[0029] In this embodiment, if Figure 1 As shown, the guide rod 105 and the lifting arm 103 are detachably connected via a locking screw. Furthermore, a stepped through hole is provided on the lifting arm 103, and the bottom of the guide rod 105 is fitted and installed in the large hole of the stepped through hole. A threaded hole is provided at the bottom of the guide rod 105, and the guide rod 105 is connected and locked to the lifting arm 103 via a locking screw. Therefore, the guide rod 105 and the lifting arm 103 can be quickly disassembled and assembled, which is convenient for the assembly of the silkworm foil clamping arm.

[0030] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
