Description

Technical Field

[0001] The utility model relates to an automated silkworm breeding technology, in particular to a silkworm foil clamping device. 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 silkworm foil will be deformed, resulting in an irregular shape, making it difficult for the robot to use the deformed silkworm foil. In addition, in order to control costs, the accuracy requirements for the clamping robot that clamps the silkworm foil are not too high, which leads to low accuracy of the clamping robot during movement. As a result, when clamping the silkworm foil, some of the silkworm foil cannot enter the clamping groove of the clamping unit, which makes the clamping robot unable to clamp the silkworm foil stably and effectively. In severe cases, the silkworm foil may be squeezed and damaged. Utility Model Content

In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0031] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] like Figure 1 As shown, a silkworm foil clamping device comprises a mounting frame 121 and a clamping unit 100, two clamping units 100 are slidably mounted on both left and right ends of the mounting frame 121, preferably, the mounting frame 121 is a flat plate, screw holes are provided on the mounting frame 121, so as to facilitate the installation of the mounting frame 121 and the manipulator, the manipulator is a prior art, and a multi-axis manipulator can be selected according to needs, in this embodiment, the two clamping units 100 are arranged at intervals, and in the initial state of the clamping units 100, the spacing between the two clamping units 100 is greater than the width of the silkworm foil, so as to facilitate the clamping of the silkworm foil, further, a driving mechanism for driving the two clamping units 100 to move toward or away from each other is also installed on the mounting frame 121, when the driving mechanism is working, it drives the two clamping units 100 to move toward or away from each other, so that the two clamping units 100 clamp the silkworm foil or release the silkworm foil.

[0033] In this embodiment, if Figure 5As shown, the clamping unit 100 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 the gravity of the lifting arm 103. Both ends of the lifting arm 103 are installed with clamping mechanisms, and the clamping mechanism has a clamping groove, and the entrance of the clamping groove is a bell mouth. Through the bell mouth, the clamping mechanism can use silk foils of different sizes, especially after the silk 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.

[0034] After the silkworm foil is used for a period of time, although the silkworm foil is deformed, the structural strength of the four corners of the silkworm foil is relatively high. Under normal circumstances, the four corners of the silkworm foil will not be deformed too much, while the middle area of ​​the silkworm foil will be more obviously arched or bent down. In the process of clamping the silkworm foil, the middle two sides of the side of the silkworm foil are mainly clamped, and the arched or bent silkworm foil will affect the clamping of the silkworm foil by the clamping mechanism. In this embodiment, if Figure 5 As shown, the clamping mechanism includes a guide piece 108 and a lifting piece 107, and the lifting piece 107 and the guide piece 108 are both installed 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 upwardly inclined first guide slope 109 is provided on the end of the guide piece 108 away from the lifting arm 103, and a downwardly inclined second guide slope 110 is provided on the end of the lifting piece 107 away from the lifting arm 103. The first guide slope 109 and the second guide slope 110 form a bell mouth. When 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 is clamping the silkworm foil, the silkworm foil is deformed, resulting in irregularity. After the first guide slope 109 contacts the silkworm foil, as the clamping mechanisms of the two clamping units 100 gradually move closer to the silkworm foil, the silkworm foil applies an upward thrust to the lifting arm 103 through the first guide slope 109, thereby causing the linear guide mechanism to move upward, thereby causing the clamping mechanism to move upward, thereby causing the clamping groove to be aligned with the silkworm foil, and finally clamping the silkworm foil. Therefore, a trumpet mouth is formed by the first guide slope 109 and the second guide slope 110, so that the deformed silkworm foil can still enter the clamping groove, and through the linear guide mechanism, the horizontal height of the clamping groove can be adjusted according to the actual situation of the silkworm foil, thereby ensuring the reliability of the silkworm foil clamping.

[0035] In this embodiment, if Figure 5As 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. The support arms 102 are cantilevers. After the two support arms 102 are connected by the connecting rod 106 and the mounting plate, the structural strength of the support arms 102 can be increased, thereby increasing the carrying capacity of the silkworm foil clamping unit.

[0036] In this embodiment, if Figure 5 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.

[0037] In this embodiment, if Figure 5 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.

[0038] In this embodiment, if Figure 5 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 and the lifting arm 103 are connected and locked by the 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 unit.

[0039] In this embodiment, if Figure 5As shown, the clamping unit 100 also includes a sliding plate 101, one end of the support arm 102 close to the mounting frame 121 is connected to the sliding plate 101, and the sliding plate 101 is slidably mounted on the bottom of the mounting frame 121 through a linear motion pair, and the linear motion pair belongs to the prior art, and is optional, such as Figure 2 As shown, the linear motion pair includes a linear slide 127 and a slider 128. The slider 128 is mounted on the sliding plate 101, and the linear slide 127 is mounted on the mounting frame 121. The linear slide 127 is arranged along the telescopic direction of the clamping unit 100, the slide is mounted on the mounting frame 121, and a slide groove is installed on the slider 128. The slider 128 is mounted on the clamping unit 100, and the slide groove is slidably matched on the linear slide 127. In this embodiment, after the silkworm foil is grabbed, it is necessary to move the silkworm foil to a specified position, so the silkworm foil is usually located at the bottom. Therefore, in order to ensure the reliability of the connection between the slider 128 and the linear slide 127, the slide groove is optionally a dovetail groove. Of course, the structure of the linear slide 127 must also be adapted according to the dovetail groove, thereby ensuring the sliding match between the linear slide 127 and the dovetail groove. Further, in this embodiment, the linear motion pair is two groups, and is arranged at intervals. Through the two groups of linear motion pairs, the straightness of the movement of the clamping unit 100 is further guaranteed.

[0040] In this embodiment, if Figure 2 As shown, the driving mechanism includes a driving motor 122, a support shaft 123 and a synchronous belt. The support shaft 123 is installed on the mounting frame 121 through a bearing seat. The driving motor 122 is installed on the mounting frame 121, and the power output end of the driving motor 122 is connected to the support shaft 123. At least two driving pulleys are installed on the support shaft 123. Driven pulleys corresponding to the driving pulleys are also installed at both ends of the mounting frame 121. A synchronous belt is wrapped around the driving pulley and the driven pulley. The synchronous belt is connected to the corresponding clamping unit 100. The driving motor 122 works, thereby driving the support shaft 123 to rotate, thereby causing the driving pulley to rotate. After the driving pulley rotates, it drives the synchronous belt to move. When the synchronous belt moves, it drives the clamping unit 100 to move.

[0041] In this embodiment, if Figure 1 and Figure 3As shown, a pressing block 126 is installed on the sliding plate 101, and the synchronous belt is connected to the corresponding pressing block 126. Further, the pressing block 126 includes a pressing plate 131 and a fixing seat 132. The fixing seat 132 is installed on the mounting frame 121, and the pressing plate 131 is installed on the fixing seat 132. The pressing plate 131 and the fixing seat 132 clamp the belt body of the corresponding synchronous belt. During installation, the fixing seat 132 is detachably installed on the mounting frame 121 by a locking screw, and then the synchronous belt is placed on the fixing seat 132, and then the fixing seat 132 and the pressing plate 131 are locked by screws. Through the clamping of the pressing plate 131 and the fixing seat 132, the synchronous belt and the sliding plate 101 move synchronously. In this embodiment, in order to ensure the reliability of the synchronous belt being clamped by the pressing plate 131 and the fixing seat 132, as shown in FIG. Figure 4 As shown, an anti-slip structure is provided on the clamping surface of the fixed seat 132. Optionally, the anti-slip structure is a plurality of convex teeth arranged at intervals. The convex teeth of the fixed seat 132 are engaged with the convex teeth on the synchronous belt, and the synchronous belt is tightened and cannot slip, thereby ensuring the synchronous movement between the synchronous belt and the sliding plate 101.

[0042] In this embodiment, if Figure 2 and Figure 3As shown, two driving pulleys are installed on the support shaft 123, one of which is equipped with a first synchronous belt 124, and the other is equipped with a second synchronous belt 125, and the pressing block 126 clamps the process belt body 133 of the corresponding synchronous belt. In this embodiment, when the mounting frame 121 is placed horizontally, the driving motor 122 is installed on the bottom of the mounting frame 121 through a motor bracket, and the bearing seat is also installed at the bottom of the mounting frame 121, wherein the first synchronous belt 124 is located on the left side of the mounting frame 121, and the second synchronous belt 125 is located on the right side of the mounting frame 121, the belt body on the upper side of the first synchronous belt 124 is the process belt body 133, the belt body on the lower side of the first synchronous belt 124 is the return belt body 134, and the belt body on the lower side of the second synchronous belt 125 is the process belt body 133, and the belt body on the upper side of the second synchronous belt 125 is the return belt body 134, that is, the belt body on the upper side of the first synchronous belt 124 is connected to the pressing block 126, and the second The belt body on the lower side of the synchronous belt 125 is connected to the pressure block 126. When in use, when the driving motor 122 rotates forward, the driving support shaft 123 rotates. At this time, the two pressure blocks 126 move toward each other, thereby driving the two clamping units 100 to move toward each other, thereby shortening the distance between the two clamping units 100, and then clamping the silkworm foil. When the silkworm foil needs to be released, the driving motor 122 rotates in the opposite direction, thereby causing the two clamping units 100 to move back to back, thereby increasing the distance between the two clamping units 100, thereby releasing the silkworm foil. In this embodiment, a position sensor 129 for detecting the position of the sliding plate 101 is installed on the top of the mounting frame 121, and in order to facilitate the position sensor 129 to detect the sliding plate 101, a through hole is opened on the mounting frame 121. During the silkworm foil release process, when the position sensor 129 detects the sliding plate 101, it indicates that the sliding plate 101 has returned to the initial position and the silkworm foil release is completed.

[0043] The working process of the utility model is as follows: when it is necessary to clamp the silkworm foil, the driving motor 122 rotates forward, and the driving support shaft 123 rotates forward. At this time, under the action of the synchronous belt, the two pressing blocks 126 move toward each other, thereby driving the two clamping units 100 to move toward each other, thereby shortening the distance between the two clamping units 100, and then clamping the silkworm foil. When the clamping unit 100 contacts the silkworm foil, if the second guide slope 110 on the lifting sheet 107 contacts the silkworm foil first, at this time, the silkworm foil is lifted up under the action of the second guide slope 110, and as the clamping unit 100 continues to approach, the silkworm foil enters the clamping groove, thereby completing the clamping of the silkworm foil. If the first guide slope 109 contacts the silkworm foil, as the clamping unit As the two clamping units 100 continue to approach each other, the silkworm foil applies an upward reaction force to the first guide slope 109, and the linear axis moves upward under the action of the reaction force, so that the clamping groove can be aligned with the silkworm foil, and finally the silkworm foil enters the clamping groove. Of course, if the silkworm foil and the clamping groove are in an aligned state, the silkworm foil directly enters the clamping groove. After the silkworm foil is clamped, when the silkworm foil reaches the specified position and needs to be released, the driving motor 122 rotates in the opposite direction, so that the two clamping units 100 move back to back, thereby increasing the distance between the two clamping units 100, so that the clamping groove is separated from the silkworm foil, and then the silkworm foil is released, and the lifting arm 103 is in the downstroke under the action of gravity, thereby completing the clamping and release of the silkworm foil.
