This multi-power-source baffle assembly device not only increases structural complexity and space requirements but also raises manufacturing costs and maintenance difficulties. Furthermore, redundant drive units increase energy consumption, hindering energy-efficient operation. Utility Model Content

[0022] The baffle strip assembling device provided by the present application is used to load the baffle strips into the positions corresponding to the box opening inside the packaging box. In a square packaging box, at least the baffle strips are loaded onto the two opposite side surfaces of the packaging box. In the present application, the baffle strip assembling device can load three integrally connected baffle strips (three-segment baffle strip 40) into the three side surfaces of the packaging box. As Figure 1 shown, the three-segment baffle strip 40 includes a first segment 41, a middle segment 42 and a tail segment 43 connected in sequence. The baffle strip assembling device mainly grips the first segment 41 and the tail segment 43 to form a "U" shape, sends the three-segment baffle strip 40 into the interior of the packaging box, and correspondingly connects it with three connected side walls of the square packaging box.

[0023] Reference Figures 2 to 7This application provides a mounting bar device, including a mounting frame 10, and a drive device 11, a left robotic arm 20, and a right robotic arm 30 mounted on the mounting frame 10. The left robotic arm 20 and the right robotic arm 30 are spaced apart in the horizontal direction. It should be noted that in this application, the vertical direction is, for example, the direction of gravity, and the horizontal direction is, for example, the direction perpendicular to the horizontal. The left robotic arm 20 includes a left transmission assembly 21 and a left swing arm 22 connected to each other; the right robotic arm 30 includes a right transmission assembly 31 and a right swing arm 32 connected to each other; the drive device 11 drives the left robotic arm 20 and the right robotic arm 30 to move together in the vertical direction, and the left transmission assembly 21 and the right transmission assembly 31 move in the vertical direction under the drive of the drive device 11, and then respectively drive the left swing arm 22 and the right swing arm 32 to swing in the horizontal direction.

[0024] Specifically, the left swing arm 22 and the right swing arm 32 can be connected to the first segment 41 and the last segment 43 of the three-section retaining strip 40, respectively. The middle segment 42 retaining strip can be located at the bottom of the left swing arm 22 and the right swing arm 32. The drive device 11 can first drive the entire left robotic arm 20 and the right robotic arm 30 to move downward together, so that the middle segment 42 retaining strip is installed on the first side of the packaging box. Specifically, during the downward movement of the drive device 11, the left transmission component 21 and the right transmission component 31 move downward together under the drive of the drive device 11, so that the middle segment 42 retaining strip is installed on the first side of the packaging box. As the drive device 11 continues to move downward, the left transmission component 21 and the right transmission component 31 can make the left swing arm 22 and the right swing arm 32 swing horizontally, so that the first segment 41 and the last segment 43 of the three-section retaining strip 40 are installed on the two adjacent sides of the first side, thus completing the installation of the three-section retaining strip into the packaging box. By using only one drive unit 11, i.e., only one power source to drive the left robotic arm 20 and the right robotic arm 30 to move in the first direction, and since the left robotic arm 20 and the right robotic arm 30 are respectively equipped with a left transmission component 21 and a right transmission component 31, after being driven by the drive unit 11 to move in the first direction, the left swing arm 22 and the right swing arm 32 can then drive them to swing in the second direction. Only a single drive component is needed to simultaneously control the vertical movement and horizontal swing of the left and right operators, completely solving the technical pain point of traditional devices requiring three independent power sources. This results in a simple structure and facilitates energy-saving optimization of equipment operation. The left transmission assembly 21 and the right transmission assembly 31 respectively convert their own movement along the first direction into driving their corresponding swing arms to move in the horizontal direction. The transmission structure that the left transmission assembly 21 and the right transmission assembly 31 can adopt is, for example, a screw drive, which uses the relative movement between the screw rod and the nut to convert the vertical linear motion into the horizontal motion; or a chain drive, which uses a chain and pulley system to convert the vertical motion into the horizontal motion; or a crank-connecting rod mechanism to convert the vertical motion into the horizontal motion.

[0025] In one embodiment, the mounting bracket 10 is provided with a second sliding pair 13, which includes a second guide rail 131 and a second slider 132 disposed on the second guide rail 131; the second guide rail 131 extends horizontally, and the second slider 132 slides horizontally; one of the right robotic arm 30 and the left robotic arm 20 is connected to the second slider 132 and moves along the extension direction of the second guide rail 131. In one embodiment, as... Figures 4 to 5 As shown, the right robotic arm 30 is connected to the second slider 132, which is slidably mounted on the second guide rail 131, allowing the right robotic arm 30 to slide horizontally to adjust the lateral distance between the right robotic arm 30 and the left robotic arm 20. The second slider 132 is connected to a cylinder, which drives the second slider 132 to move horizontally on the second guide rail 131, thereby moving the right robotic arm 30 horizontally. In other embodiments, the second slider 132 can also be manually moved to move the right robotic arm 30 horizontally, adjusting the distance between the left robotic arm 20 and the right robotic arm 30 to accommodate different packaging box sizes, allowing the mounting strip device to adapt to the length of the middle section 42 of the three-section mounting strip 40. By setting only one horizontally positioned second sliding joint 13, the left robotic arm 20 is fixed to the mounting bracket 10, and the right robotic arm 30 can move horizontally. Adjusting only one robotic arm is sufficient to adjust the distance between the left robotic arm 20 and the right robotic arm 30, resulting in a simple structure and convenient operation.

[0026] In one implementation, such as Figure 2 and Figure 3 As shown, the mounting device also includes a pressure plate 12, which is positioned above the left robotic arm 20 and the right robotic arm 30. The driving device 11 can drive the pressure plate 12 to move vertically. Under the action of the driving device 11, the pressure plate 12 can compress the left robotic arm 20 and the right robotic arm 30, thereby causing them to move vertically. Specifically, the pressure plate 12 is positioned on top of the left robotic arm 20 and the right robotic arm 30. The driving device 11 is, for example, a cylinder, with an actuating block 14 protruding from it. The actuating block 14 protrudes from the cylinder and is positioned above the pressure plate 12, spaced apart from it. Under the drive of the cylinder, the actuating block 14 can move vertically, for example, moving downwards towards the pressure plate 12; or moving upwards away from the pressure plate 12. When the actuating block 14 moves downwards in the vertical direction, it can squeeze the pressure plate 12 downwards, thereby driving the left robotic arm 20 and the right robotic arm 30 to move downwards together. In other embodiments, the pressure plate 12 can be directly connected to a cylinder, and the cylinder can directly drive the pressure plate 12 to move, which in turn drives the left robotic arm 20 and the right robotic arm 30 to move together.

[0027] In one implementation, such as Figure 2 and Figure 3 As shown, the left robotic arm 20 and the right robotic arm 30 have the same structure and are symmetrically arranged about a vertical central axis, for example, mirror-symmetrically arranged along the vertical direction. Understandably, by drawing a vertical central axis between the left robotic arm 20 and the right robotic arm 30, and with the components assembled in a mirror-symmetrical manner along the axis of symmetry, the left robotic arm 20 and the right robotic arm 30 can perform mirror-symmetrical operations on the first and last segments of the three-segment stop bar 40. For example, they can control the left swing arm 22 and the right swing arm 32 to move closer to each other; or control the left swing arm 22 and the right swing arm 32 to move further away from each other.

[0028] In one implementation, such as Figures 2 to 5 As shown, the left swing arm 22 has a top end 221 and a bottom end 222 in the vertical direction. The bottom end 222 of the left swing arm 22 is rotatably connected to the left transmission assembly 21. The left transmission assembly 21 is provided with an elastic element 23. The elastic element 23 is connected to the side of the left swing arm 22 away from the right swing arm 32. The elastic element 23 is used to provide a force to the top end 221 of the left swing arm 22 to swing along the right swing arm 32. Specifically, the left swing arm 22 is elongated and has a top end 221 and a bottom end 222 in the vertical direction. The bottom end 222 of the left swing arm 22 is rotatably connected to the bottom end 222 of the left transmission assembly 21. For example, the left swing arm 22 is rotatably connected to the left transmission assembly 21 via a rotating shaft. An elastic element 23 is connected to the side of the left swing arm 22 away from the right swing arm 32. The two ends of the elastic element 23 are connected to the left swing arm 22 and the left transmission assembly 21, respectively. The elastic element 23 is, for example, a first spring, which provides a force to the top end 221 of the left swing arm 22 to swing closer to the right swing arm 32. Understandably, the first spring compresses the left swing arm 22, causing the top end 221 of the left swing arm 22 to swing closer to the right swing arm 32.

[0029] Similarly, the right swing arm 32 has a top end 221 and a bottom end 222 in the vertical direction. The bottom end 222 of the right swing arm 32 is rotatably connected to the right transmission assembly 31. The right transmission assembly 31 is provided with an elastic element 23, which is connected to the right swing arm 32. The elastic element 23 is used to provide a force for the top end 221 of the right swing arm 32 to swing close to the left swing arm 22. Specifically, the right swing arm 32 is elongated and has a top end 221 and a bottom end 222 in the vertical direction. The bottom end 222 of the right swing arm 32 is rotatably connected to the bottom end 222 of the right transmission assembly 31. For example, the right swing arm 32 is rotatably connected to the right transmission assembly 31 through a rotating shaft. An elastic element 23 is connected to the side of the right swing arm 32 away from the left swing arm 22. The two ends of the elastic element 23 are connected to the right swing arm 32 and the right transmission assembly 31, respectively. The elastic element 23 is, for example, a first spring, which is used to provide a force for the top end 221 of the right swing arm 32 to swing closer to the left swing arm 22. Understandably, the first spring compresses the right swing arm 32, causing the top end 221 of the right swing arm 32 to tilt closer to the left swing arm 22.

[0030] Under the action of the elastic element 23, when the mounting device is in its initial state, the left swing arm 22 tilts towards the right swing arm 32, and the right swing arm 32 tilts towards the left swing arm 22. Since the left swing arm 22 and the right swing arm 32 are used to fix the first segment 41 and the last segment 43 of the three-section mounting strip 40, the left swing arm 22 and the right swing arm 32 can make the first segment 41 and the last segment 43 tilt towards each other, so that the three-section mounting strip 40 forms a triangular shape. When the mounting device sends the three-section mounting strip 40 into the box opening, it avoids interference between the first and last segments of the mounting strip and the side wall of the packaging box, which would affect the assembly of the three-section mounting strip 40.

[0031] In one implementation, such as Figures 2 to 5 As shown, the left transmission assembly 21 includes a first sliding pair 211, a first transmission member 212, and a second transmission member 213. The first sliding pair 211 includes a first guide rail 2111 and two first sliders 2112; the first guide rail 2111 extends vertically, and the two first sliders 2112 are independently disposed on the first guide rail 2111. The first transmission member 212 and the second transmission member 213 are respectively connected to the two first sliders 2112 in a one-to-one correspondence, and the first transmission member 212 and the second transmission member 213 are flexibly connected.

[0032] Specifically, the first guide rail 2111 extends vertically, and two first sliders 2112 are independently arranged and slidably connected to the first guide rail 2111 respectively. The two first sliders 2112 form an upper sliding block and a lower sliding block, which are arranged vertically and can each move independently on the first moving pair 211 in the vertical direction. The first transmission member 212 and the second transmission member 213 are connected to the upper sliding block and the lower sliding block respectively; and the first transmission member 212 and the second transmission member 213 are flexibly connected, for example, by an elastic rope or by a spring. The upper sliding block is connected to the first transmission member 212, and the lower sliding block is connected to the second transmission member 213, so that the first transmission member 212 is located above the second transmission member 213; the first transmission member 212 and the second transmission member 213 can move together in the same vertical direction, or they can move closer to or further away from each other in the vertical direction.

[0033] The first transmission component 212 can be connected to the pressure plate 12. The pressure plate 12 mainly acts on the first transmission component 212. The driving device 11 drives the pressure plate 12 to move, and then acts on the first transmission component 212 through the pressure plate 12, so that the first transmission component 212 and the second transmission component 213 move downward together. When the second transmission component 213 is restricted in its movement, the first transmission component 212 can continue to move downward and move closer to the second transmission component 213. The first transmission component 212 and the second transmission component 213 move closer to each other. The left swing arm 22 and the elastic component 23 are provided on the second transmission component 213. The bottom end 222 of the left swing arm 22 is rotatably connected to the second transmission component 213 through a rotating shaft. One end of the elastic component 23 is connected to the side of the left swing arm 22 away from the right swing arm 32, and the other end is connected to the second transmission component 213. The top end 221 of the left swing arm 22 is a free end. The elastic component 23 allows the top end 221 of the left swing arm 22 to swing left and right.

[0034] Similarly, the right transmission assembly 31 has the same structure as the left transmission assembly 21, and the elastic element 23 allows the top end 221 of the right swing arm 32 to swing left and right. Specifically, the right transmission assembly 31 includes a first sliding joint 211, a first transmission element 212, and a second transmission element 213. The first sliding joint 211 includes a first guide rail 2111 and two first sliders 2112; the first guide rail 2111 extends vertically, and the two first sliders 2112 are independently disposed on the first guide rail 2111. The first transmission element 212 and the second transmission element 213 are respectively connected to the two first sliders 2112 in a one-to-one correspondence, and the first transmission element 212 and the second transmission element 213 are flexibly connected. The first guide rail 2111 extends vertically, and the two first sliders 2112 are independently disposed and slidably connected to the first guide rail 2111 respectively; the two first sliders 2112 form an upper sliding block and a lower sliding block, which are disposed vertically and can each move independently on the first sliding joint 211 in the vertical direction. The first transmission member 212 and the second transmission member 213 are respectively connected to the upper sliding block and the lower sliding block; and the first transmission member 212 and the second transmission member 213 are flexibly connected, for example, the first transmission member 212 and the second transmission member 213 are connected by an elastic rope or by a spring. The upper sliding block is connected to the first transmission member 212, and the lower sliding block is connected to the second transmission member 213, so that the first transmission member 212 is located above the second transmission member 213; the first transmission member 212 and the second transmission member 213 can move together in the same vertical direction, or they can move closer to or further away from each other in the vertical direction. The right swing arm 32 and the elastic element 23 are mounted on the second transmission element 213. The bottom end 222 of the right swing arm 32 is rotatably connected to the second transmission element 213 via a rotating shaft. One end of the elastic element 23 is connected to the side of the right swing arm 32 away from the left swing arm 22, and the other end is connected to the second transmission element 213. The top end 221 of the right swing arm 32 is a free end, and the elastic element 23 allows the top end 221 of the right swing arm 32 to swing left and right.

[0035] In one embodiment, taking the left drive assembly 21 as an example, refer to... Figure 6The first transmission member 212 includes a base 2121 and an extension 2122 connected to each other. The extension 2122 protrudes from the base 2121 and extends downward in a vertical direction, forming an elongated shape. The end of the extension 2122 away from the base 2121 and the side away from the right swing arm 32 gradually narrows to form a contraction portion 2123. An interference portion 24 protrudes from the left swing arm 22 and is located on the side of the extension 2122 away from the right swing arm 32. In one embodiment, the interference portion 24 is, for example, a bearing, to reduce the friction between the interference portion 24 and the extension 2122. In the initial state, the interference portion 24 is located at the contraction portion 2123. Due to the action of the elastic member 23, the interference portion 24 abuts against the contraction portion 2123, and the top end 221 of the left swing arm 22 tilts towards the right swing arm 32. When the drive device 11 causes the first transmission member 212 to move downward, the second transmission member 213 is first stopped by the panel below the box, thus restricting its downward movement. The first transmission member 212 continues to move downward, and the interference portion 24 gradually moves upward along the contour of the contraction portion 2123 on the extension portion 2122. Since the contraction portion 2123 gradually shrinks towards its end, the extension portion 2122 gradually increases in size as it moves upward. The interference portion 24 moves along the contour of the extension portion 2122, causing the left swing arm 22 to gradually move away from the right swing arm 32, and the elastic member 23 is continuously compressed. Therefore, the left swing arm 22 is gradually straightened; understandably, the left swing arm 22 gradually straightens in the vertical direction. The first section 41 stop bar fixed on the left swing arm 22 gradually moves towards the side wall inside the packaging box until the stop bar is completely in contact with the side wall.

[0036] Similarly, the first transmission member 212 of the right transmission assembly 31 has the same structure as the first transmission member 212 of the left transmission assembly 21 and is symmetrically arranged in the vertical direction. The interference part 24 on the right transmission assembly 31 moves along the contour of the extension part 2122, which can make the right swing arm 32 gradually move away from the left swing arm 22, so that the right swing arm 32 is gradually straightened. The first section 41 stop bar fixed on the right swing arm 32 gradually moves towards the side wall inside the packaging box until the stop bar is completely in contact with the side wall.

[0037] In one implementation method, such as Figure 2 , Figure 7As shown, the left transmission assembly 21 also includes a connecting rod 214 and a second spring 215. The second spring 215 is sleeved on the outside of the connecting rod 214. The base 2121 and the second transmission member 213 are respectively provided with sliding grooves 216. The two ends of the connecting rod 214 are respectively located in the two sliding grooves 216. The second spring 215 is located between the base 2121 and the second transmission member 213. The sliding groove 216 on the base 2121 has an opening near the end of the second transmission member 213, and the sliding groove 216 on the second transmission member 213 also has an opening near the end of the base 2121. Each opening communicates with its respective sliding groove 216. The two ends of the connecting rod 214 pass through the two openings and are fixed in the two sliding grooves 216. The connecting rod 214 includes a rod portion 2141 and locking caps 2142 located at both ends of the rod portion 2141. The radial dimension of the locking caps 2142 is larger than the radial dimension of the rod portion 2141, and the opening size is larger than the radial dimension of the rod portion 2141 but smaller than the radial dimension of the locking caps 2142.
