[0038] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments in conjunction with the accompanying drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.

[0039] Embodiment 1:

[0040] As Figures 1 to 9 shown, a package sleeve clamping device includes a pressing and clamping unit 100, a flipping and limiting unit 200, and an unlocking unit 300.

[0041] The pressing and clamping unit 100 includes a clamping cover 101. An electric push rod 103 is installed inside the clamping cover 101. A top rod 1031 is installed at the output end of the electric push rod 103. A top plate 1032 is welded to the bottom of the top rod 1031. A pair of strip plates 107 are installed on the top plate 1032. A swing rod 106 is slidably arranged on the strip plates 107. A rotating shaft 104 is installed at the end of the swing rod 106. A mounting plate 105 is installed on the rotating shaft 104. A clamping jaw 1051 is installed on the mounting plate 105. A vertical rod 1081 is installed at the bottom of the strip plate 107. A pressing block 108 is installed at the end of the vertical rod 1081. Among them, the electric push rod drives the top rod and the top plate to move downward. The top plate can drive the swing rods on both sides to slide on the strip plates, and drive the rotating shaft at the end of the swing rod to rotate. A mounting plate is installed on the rotating shaft. At this time, the mounting plate drives the clamping jaws to rotate, and the package sleeve is clamped by the relative rotation of the two clamping jaws. And the top plate drives the vertical rod and the pressing block at the bottom to move downward. Furthermore, the pressing block can extrude the already clamped package sleeve, thereby improving the clamping force and the clamping stability.

[0042] The flipping limit unit 200 includes a flipping plate 201, the flipping plate 201 is rotatably installed on the side wall of the clamping cover 101, a blocking plate 2022 is rotatably installed on the flipping plate 201, a gear 2042 is installed on the blocking plate 2022, a rack 2043 is meshed with the bottom of the gear 2042, a push rod 204 is installed on the rack 2043, a side rod 205 is rotatably installed on the push rod 204, the side rod 205 movably penetrates through the side wall of the clamping cover 101, and the end of the side rod 205 penetrates and is inserted into the installation cavity 1082 opened at the bottom of the pressing block 108. A swing arm 2051 is rotatably installed on the side rod 205, an extrusion block 2052 is movably installed at the end of the swing arm 2051, and the extrusion block 2052 movably penetrates through the pressing block 108. When the extrusion block in the pressing block is extruded, the side rod is driven to move outwards through the swing arm, the side rod pushes the push rod to move outwards synchronously, the gear is driven to rotate by the rack on the side rod, and then the coaxially connected blocking plate is driven to reverse, so that the moving directions on both sides of the packaging sleeve can be blocked, the situation of the packaging sleeve falling during the clamping process is reduced, and the safety is improved.

[0043] The unlocking unit 300 includes an unlocking cover 301, an L-shaped rod 3011 is installed at the bottom of the unlocking cover 301, and the L-shaped rod 3011 is connected to the ejector rod 1031. A clamping block 302 is inserted into the unlocking cover 301, a fixing block 303 is inserted into the clamping block 302, and the fixing block 303 is connected to the flipping plate 201. The electric push rod can drive the unlocking cover and the L-shaped rod to move downwards, so that the clamping block inside the unlocking cover is moved out of the fixing block to unlock the fixing block. Then, the flipping plate and the push rod rotate along the rotation center, and finally the push rod and the side rod are located on the same straight line. In this way, it can be ensured that the flipping limit unit can be flipped to the working position during the clamping process and is normally against the side wall of the clamping cover, so as to facilitate the overall movement of the clamping cover.

[0044] As Figure 1 、 Figure 2 、 Figure 3 and Figure 4 shown, in the specific implementation manner, a connecting flange 102 is installed on the clamping cover 101, a plurality of pairs of positioning holes 1021 are opened on the connecting flange 102, the connecting flange 102 is connected to the robotic arm, a notch 1011 is opened at the bottom of the clamping cover 101, the mounting plate 105 movably penetrates through the notch 1011, a through hole 1012 is opened at the central position of the clamping cover 101, and the pressing block 108 movably penetrates through the through hole 1012. The author connects the connecting flange 102 with the execution end of the robotic arm, and the internal electric push rod 103 needs to be connected to the computer controlling the robotic arm. The above connection method is the prior art and will not be elaborated here.

[0045] As Figure 4 and Figure 5As shown, further, there is a gap between a pair of strip plates 107, the swing rod 106 is movably inserted into the gap, a slide rod 1061 is installed at the end of the swing rod 106, a strip groove 1071 is formed in the strip plate 107, the strip groove 1071 is a through groove, and the slide rod 1061 is slidably arranged in the strip groove 1071. The swing rod 106 is in an inclined state, the height of one end of the swing rod 106 where the slide rod 1061 is installed is higher than that of the other side, and the shortest distance from the end of the swing rod 106 where the slide rod 1061 is installed to the clamping cover 101 is less than the distance from the other side to the clamping cover 101, and a pair of swing rods 106 are in a V shape. During the downward movement of the ejector rod 1031, the ejector rod 1031 drives the top plate 1032 and the installed strip plate 107 to move downward synchronously. Among them, the slide rod 1061 is slidably arranged in the strip groove 1071 on the strip plate 107, and at this time, the slide rod 1061 slides in the strip groove 1071. During the sliding process of the slide rod 1061, the swing rod 106 where the slide rod 1061 is installed changes its angle.

[0046] Embodiment 2:

[0047] Different from the above embodiment and this embodiment: As Figure 4 、 Figure 5 and Figure 6 shown, bearings 1042 are clamped on both sides of the rotating shaft 104, a bearing seat 1041 is clamped on the outer wall of the bearing 1042, the bottom of the bearing seat 1041 is welded to the inner side wall of the clamping cover 101, and the height of the rotating shaft 104 is higher than the height of the top of the pressing block 108. During the sliding process of the slide rod 1061, the swing rod 106 where the slide rod 1061 is installed drives the rotating shaft 104 to rotate inside the bearing seat 1041, and the bearing 1042 inside the bearing seat 1041 can reduce the friction during the rotation process. After the rotating shaft 104 rotates, it can drive the mounting plate 105 and the clamping jaw 1051 at the end to rotate inward, so as to clamp the packaging sleeve at the central position.

[0048] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 6 shown, in the specific implementation, the bottoms of the clamping jaws 1051 and the pressing blocks 108 are both placed outside the clamping cover 101. An anti-slip pad is installed on the inner wall of the clamping jaw 1051, a buffer plate is installed at the bottom of the pressing block 108, and the mutual surfaces of the clamping jaw 1051 and the pressing block 108 are both arc-shaped. The top plate 1032 drives the vertical rod 1081 and the pressing block 108 to move downward continuously, so as to closely fit the pressing block 108 and the packaging sleeve, thereby improving the clamping stability. The anti-slip pad can increase the friction, thereby improving the stability during the clamping process.

[0049] As Figure 4 andFigure 8 As shown, further, a synchronous plate 2011 is installed on the back surface of the flipping plate 201. A limit seat 2041 is installed on the synchronous plate 2011. A push rod 204 is movably inserted into the limit seat 2041. A soft pad 202 is installed on the baffle plate 2022. The back surface of the baffle plate 2022 is in contact with a positioning block 2021 installed on the side wall of the clamping cover 101. A positioning shaft 2023 is installed at the rotation center of the baffle plate 2022, and the positioning shaft 2023 is movably hinged to the mounting seat on the synchronous plate 2011.

[0050] Embodiment 3:

[0051] Based on the above embodiments, the difference from this embodiment is that: As Figure 4 and Figure 8 shown, the rotation center of the flipping plate 201 and the rotation center of the push rod 204 are located on the same straight line. A positioning seat 2012 is rotatably installed at the rotation center of the flipping plate 201. The positioning seat 2012 is welded to the side wall of the clamping cover 101. A torsion spring is clamped and arranged on the positioning seat 2012 and the rotation center of the flipping plate 201.

[0052] As Figure 8 and Figure 9 shown, in the specific implementation, a positioning rod 2061 is installed on the extrusion block 2052. A positioning sleeve 206 is inserted into the positioning rod 2061, and the positioning sleeve 206 is welded to the inner wall of the installation cavity 1082. A sliding plate 2062 is slidably arranged inside the positioning sleeve 206. A positioning rod 2061 is installed at the bottom of the sliding plate 2062, and a return spring 2063 is sleeved on the positioning rod 2061. One end of the return spring 2063 is clamped to the bottom of the sliding plate 2062, and the other end is clamped to the inner wall of the positioning sleeve 206. During the upward movement of the extrusion block 2052, the positioning rod 2061 is driven to move inside the positioning sleeve 206, and then the sliding plate 2062 slides inside the positioning sleeve 206, thereby stretching the return spring 2063. The stretched return spring 2063 facilitates the later resetting process of the extrusion block 2052.

[0053] As Figure 6 and Figure 7As shown in the figure, further, an unlocking cavity 3012 is formed at the bottom of the unlocking cover 301. A baffle 3022 is slidably arranged inside the unlocking cavity 3012. The baffle 3022 is in contact with the clamping block 302. An unlocking spring 3023 is clamped between the bottom of the baffle 3022 and the inner wall of the unlocking cavity 3012. The compression direction of the unlocking spring 3023 is the same as the moving direction of the baffle 3022. An inclined surface 3021 is arranged on one side surface of the clamping block 302. A clamping groove 3031 is formed inside the fixing block 303. The clamping block 302 is inserted into the clamping groove 3031, and the fixing block 303 is inserted into the clamping hole 1013 formed in the side wall of the clamping cover 101. When the electric push rod 103 is started, the ejector rod 1031 connected to the output end is driven to move downward by the electric push rod 103. After the ejector rod 1031 moves downward, the L-shaped rod 3011 on the side wall can be driven to move downward, pulling the unlocking cover 301 and the clamping block 302 on the surface to be separated from the clamping groove 3031 on the fixing block 303. Then, at this time, the synchronous plate 2011 and the flipping plate 201 are driven to reverse by the torsion spring, and finally the push rod 204 and the side rod 205 on the synchronous plate 2011 move to the same straight line, facilitating the side rod 205 to push the push rod 204 to move. During the later resetting, the electric push rod 103 retracts to the specified position, and the synchronous plate 2011 is manually flipped. The inclined surface 3021 of the clamping block 302 is squeezed by the fixing block 303 on the synchronous plate 2011. At this time, the clamping block 302 retracts into the unlocking cover 301. Until it moves to the position of the clamping groove 3031, at this time, the unlocking spring 3023 drives the clamping groove 3031 to reset. By this means, the synchronous plate can be opened at the specified position, ensuring that during the normal movement of the clamping cover, the volume becomes smaller and it is more convenient to move.

[0054] The implementation principle of a package sleeve clamping device in this embodiment is as follows:

[0055] When the device needs to be used, the operator connects the connecting flange 102 to the execution end of the robotic arm, and the internal electric push rod 103 needs to be connected to the computer controlling the robotic arm. The above connection method is prior art and will not be elaborated here.

[0056] After the device moves to the specified position, the electric push rod 103 is activated. The push rod 1031 connected to the output end drives the push rod 1031 to move downward. After the push rod 1031 moves downward, it can drive the L-shaped rod 3011 on the side wall to move downward, pulling the unlocking cover 301 and the clamping block 302 on the surface to separate from the card slot 3031 on the fixed block 303. Then, at this time, the torsion spring drives the synchronous plate 2011 and the flipping plate 201 to reverse. Finally, the push rod 204 and the side rod 205 on the synchronous plate 2011 move to the same straight line, facilitating the side rod 205 to push the push rod 204 to move. During the later reset, the electric push rod 103 retracts to the specified position, and the synchronous plate 2011 is manually flipped. The fixed block 303 on the synchronous plate 2011 squeezes the inclined surface 3021 of the clamping block 302. At this time, the clamping block 302 retracts into the unlocking cover 301. Until it moves to the position of the card slot 3031, at this time, the unlocking spring 3023 drives the card slot 3031 to reset. By this method, the synchronous plate can be opened at the specified position, ensuring that during the normal movement of the clamping cover, the volume becomes smaller and it is more convenient to move.

[0057] During the downward movement of the push rod 1031, the push rod 1031 drives the top plate 1032 and the installed strip plate 107 to move downward synchronously. A sliding rod 1061 is slidably arranged in the strip groove 1071 on the strip plate 107, and the sliding rod 1061 slides in the strip groove 1071 at this time.

[0058] During the sliding of the sliding rod 1061, the swing rod 106 equipped with the sliding rod 1061 rotates the rotating shaft 104 inside the bearing seat 1041. The bearing 1042 inside the bearing seat 1041 can reduce the friction during rotation. After the rotating shaft 104 rotates, it can drive the mounting plate 105 and the clamping jaw 1051 at the end to rotate inward. Thus, the package sleeve at the center position can be clamped. During the clamping process, the top plate 1032 drives the vertical rod 1081 and the pressing block 108 to move downward continuously. Thus, the pressing block 108 and the package sleeve can be closely attached, improving the clamping stability.

[0059] During the process of the pressing block 108 being attached to the package sleeve, the internal extrusion block 2052 is synchronously pressured and starts to move upward. Thus, the swing arm 2051 on the extrusion block 2052 drives the side rods 205 on both sides to move to both sides. The side rods 205 can finally drive the push rod 204 that has been flipped to the same straight line to move. At this time, the push rod 204 slides in the limit seat 2041. During the sliding process, the rack 2043 at the end of the push rod 204 drives the gear 2042 to rotate. The gear 2042 drives the two side partition plates 2022 to rotate through the positioning shaft 2023. After the partition plates 2022 rotate, they can limit the two ends of the package sleeve, reducing the phenomenon of the package sleeve slipping off.

[0060] During the upward movement of the extrusion block 2052, the positioning rod 2061 is driven to move inside the positioning sleeve 206, and then the sliding plate 2062 slides inside the positioning sleeve 206, thereby stretching the return spring 2063. The stretched return spring 2063 facilitates the later resetting process of the extrusion block 2052.
