[0033] The following is a profile punching device provided by this utility model that can solve the above technical problems.

[0034] Please refer to Figure 1 and Figure 3 ,in Figure 1 This is a schematic diagram of the profile punching device in this utility model. Figure 3 This is a schematic diagram of the punching conveyor platform, punching loading and unloading robot, and tilting unloading mechanism in this utility model.

[0035] In the diagram, units with similar structures are represented by the same labels.

[0036] This embodiment provides a profile punching device for punching profiles cut by a profile cutting device. The profile punching device includes a flipping and unloading mechanism 14, a material distribution and conveying mechanism 16, a punching conveying platform 11, a punching and unloading robot 12, a punching mechanism 13, and a positioning mechanism 15. The flipping and unloading mechanism 14 is used to receive the profiles picked up and conveyed from the punching platform 131 by the punching and unloading robot 12 and place them on the riveting point conveying platform 21.

[0037] Please refer to Figure 11 In this embodiment, the profile includes a main body 31 and an extension plate 32 located on one side of the main body 31. A groove 33 is provided on the side of the main body 31 that is close to and perpendicular to the extension plate 32.

[0038] Please refer to Figure 2 The extension plate 32 of the medium profile is located at the bottom of the main body 31 when the profile is on the punching platform 131. When the profile is on the riveting point conveying platform 21, the extension plate 32 is located at the top of the main body 31. That is, the process of conveying the profile from the punching platform 131 to the riveting point conveying platform 21 requires a 180° rotation.

[0039] Please refer to Figure 1 The profile punching device includes a material conveying mechanism 16, a punching conveying platform 11, a punching loading and unloading robot 12, and a punching mechanism 13.

[0040] The punching conveyor platform 11 is located on the side of the punching mechanism 13 away from the riveting point conveyor platform 21. The material distribution conveyor mechanism 16 is movably disposed between the profile cutting device 2 and the punching conveyor platform 11. The material distribution conveyor mechanism 16 is used to take the cut profiles 3 from the profile cutting device and separately convey them to the punching conveyor platform 11. The punching loading and unloading robot 12 is movably disposed above the punching conveyor platform 11 and the punching mechanism 13. The punching loading and unloading robot 12 is used to grab and convey the profiles on the punching conveyor platform 11 to the punching mechanism 13, and to grab and unload the profiles on the punching mechanism 13. The positioning mechanism 15 includes two opposing and movably disposed positioning plates. The two positioning plates are respectively located on both sides of the end of the punching conveyor platform 11 near the punching mechanism 13. The positioning mechanism 15 extrudes and positions the profiles 3 before punching.

[0041] Please refer to Figure 1 and Figure 3 In this embodiment, two flipping feeding mechanisms 14 are respectively set at both ends of the punching platform 131 away from the punching conveying platform 11. The riveting device 4 includes a riveting conveying platform 21, which is located below the flipping feeding mechanism 14.

[0042] Please refer to Figures 4-8The flipping and unloading mechanism 14 includes: an unloading mounting plate 141, a sliding plate 143, a flipping gripper 142, a swing arm 145, and a flipping guide roller 146.

[0043] Two unloading mounting plates 141 are located on both sides of the riveting point conveying platform 21. A sliding plate 143 is slidably disposed on one side of the unloading mounting plate 141. The sliding plate 143 can move closer to or away from the riveting point conveying platform 21 by sliding. A flipping guide groove 1411 is provided on the unloading mounting plate 141. A flipping gripper 142 is rotatably connected to the sliding plate 143 through a transition post 1421. The axial direction of the transition post 1421 is perpendicular to the unloading mounting plate 141. In this embodiment, the extension direction of the clamping plate of the flipping gripper 142 is approximately the same as the axial direction of the transition post 1421. The transition post 1421 passes through the sliding plate 143 and is connected to the swing rod 145. The end of the swing rod 145 away from the transition post 1421 is connected to the flipping guide roller 146. The flipping guide roller 146 is slidably engaged in the flipping guide groove 1411.

[0044] Please refer to Figure 7 and Figure 8 The flipping guide groove 1411 includes a curved groove section 14111. The concave side of the curved groove section 14111 faces the sliding trajectory of the adapter post 1421. The maximum distance from the center line of the curved groove section 14111 to the center sliding trajectory of the adapter post 1421 is equal to the distance from the axial center line of the flipping guide roller 146 to the axial center line of the adapter post 1421. This allows the swing rod 145 to rotate 180° around the adapter post 1421 during the movement of the flipping guide roller 146 along the curved groove section 14111.

[0045] The trajectory of the flipping gripper 142 as it slides along the sliding plate 143 includes a flipping receiving position and a flipping discharging position, such as... Figure 4 The central flipping gripper 142 is located at the flipping receiving position, such as... Figure 5 The flipping gripper 142 is located at the flipping unloading position. During the process of the flipping gripper 142 moving from the flipping receiving position to the flipping unloading position, the flipping gripper 142 slides towards the riveting point conveying platform 21, the flipping guide roller 146 slides over the curved groove section 14111, and the flipping gripper 142 rotates 180° around the transition post 1421.

[0046] like Figure 7 The orientation of the rotating gripper 142 is such that when the rotating gripper 142 is in the rotating receiving position, the rotating guide roller 146 is located at the top end of the curved groove section 14111; when the sliding plate 143 is in the rotating unloading position, the rotating guide roller 146 is located at the bottom end of the curved groove section 14111. The punching loading and unloading robot 12 picks up the profile from the punching platform 131 and unloads it to the rotating gripper 142 located in the rotating receiving position. The rotating gripper 142 can hold the profile conveyed by the punching loading and unloading robot 12 and rotate and lower the profile to place it on the riveting point conveying platform 21.

[0047] It should also be noted that the flipping guide groove 1411 may also include a straight groove section 14112 connected to both ends of the curved groove section 14111. When the flipping guide roller 146 is located in the straight groove section 14112, the flipping gripper 142 can stably maintain a non-rotating state.

[0048] Please refer to Figure 6 The feeding mounting plate 141 has two sliding plates 143 slidably mounted on it. Each sliding plate 143 is rotatably connected to a flipping gripper 142. The sliding trajectory of one sliding plate 143 is inclined relative to that of the other sliding plate 143, and the distance between the two sliding plates 143 and the end of their sliding trajectories closest to the riveting point conveying platform 21 is smaller. When the two profiles are punched by the punching mechanism 13, the gap between them is relatively wide. Thus, the flipping feeding mechanism 14 can not only flip and lower the profiles, but also reduce the gap between the two profiles to accommodate the smaller conveying distance on the riveting point conveying platform 21. The flipping feeding mechanism 14 is multifunctional and highly efficient.

[0049] Please refer to Figure 6 Specifically, the flipping and unloading mechanism 14 in this embodiment also includes a linear drive module 144 and a synchronous connecting rod 1441. The linear drive module 144 can be a cylinder, an electric push rod, or other device. The synchronous connecting rod 1441 is connected to the output end of the linear drive module 144. One end of the synchronous connecting rod 1441 is fixedly connected to a sliding plate 143, and the other end of the synchronous connecting rod 1441 is movably connected to another sliding plate 143 through an elongated slot. The elongated slot can accommodate the two sliding plates 143 gradually moving closer or further apart during sliding. An extension rod 1431 can be provided between the elongated slot of the synchronous connecting rod 1441 and the sliding plate 143, and movably connected to the synchronous connecting rod 1441 to avoid interference between the synchronous connecting rod 1441 and the flipping gripper 142.

[0050] Please refer to Figure 9 and Figure 10 The material distribution and conveying mechanism 16 in this embodiment includes a material distribution and conveying drive assembly 161, a conveying frame 162, a scissor fork variable pitch linkage 163, a variable pitch drive assembly 164, and multiple material distribution support platforms 165.

[0051] The conveyor frame 162 is connected to the output end of the material distribution and conveying drive assembly 161. Multiple material distribution carriers 165 are slidably mounted on the conveyor frame 162 and connected to each other via a scissor-pitch variable-pitch linkage 163. One of the material distribution carriers 165 is connected to the output end of the variable-pitch drive assembly 164. One end of the scissor-pitch variable-pitch linkage 163 is fixedly connected to the conveyor frame 162. When the variable-pitch drive assembly 164 drives one material distribution carrier 165 to slide, the scissor-pitch variable-pitch linkage 163 can drive multiple material distribution carriers 165 to slide closer to or further away from each other. The material distribution and conveying drive assembly 161 is used to drive the material distribution carriers 165 to lift, lower, and move, thereby removing profiles from the profile cutting device 2 and separating multiple profiles by a certain distance before conveying them to the punching conveyor platform 11. This perfectly realizes the parallel cutting of multiple profiles and the subsequent separate punching and assembly processing of the profiles, resulting in high overall equipment efficiency.

[0052] Please refer to Figure 9 In this embodiment, the material distribution and conveying drive assembly 161 includes a vertical mounting plate 1611, a material distribution and transfer motor 1612, a transmission plate 1613, a guide wheel 1614, and a movable plate 1615.

[0053] The material distribution and transfer motor 1612 is fixedly connected to the vertical mounting plate 1611. The movable plate 1615 and one side of the vertical mounting plate 1611 form a sliding connection that allows for horizontal sliding and vertical lifting. The side of the vertical mounting plate 1611 near the movable plate 1615 is provided with an annular guide groove 1611. The transmission plate 1613 is located between the movable plate 1615 and the vertical mounting plate 1611. One end of the transmission plate 1613 is connected to the output end of the material distribution and transfer motor 1612, and the other end of the transmission plate 1613 is connected to the movable plate 1615 and the guide wheel 1614. The guide wheel 1614 is movably limited within the guide groove 16111. The conveyor frame 162 is connected to the top of the movable plate 1615.

[0054] The guide groove 16111 includes a vertical groove and a horizontal groove. When the guide wheel 1614 moves along the vertical groove, the movable plate 1615 is raised and lowered. When the guide wheel 1614 moves along the horizontal groove, the movable plate 1615 moves horizontally.

[0055] Please refer to Figure 5 and Figure 10 The material distribution support platform 165 includes a support plate 1651, an insert block 1652, and a limiting block 1653. Both ends of the support plate 1651 are provided with insert blocks 1652 and limiting blocks 1653. An extension plate 32 is positioned between the insert blocks 1652 and the limiting blocks 1653. The insert blocks 1652 are positioned and inserted into the sink 33, so that the material distribution support platform 165 can stably support the profile.

[0056] Here, two adjacent support plates 1651 are designated as the first support plate 1651 and the second support plate 1651, respectively. The width of the first support plate 1651 is smaller than the width of the second support plate 1651, as follows: Figure 10 The width of the first support plate 1651 at the left end is smaller than the width of its adjacent support plate 1651. The length of the first support plate 1651 is greater than or equal to the length of the second support plate 1651. Widening plates 1654 extending towards the second support plate 1651 are provided at both ends of the first support plate 1651 along its length. Insert blocks 1652 and limiting blocks 1653 on the first support plate 1651 are mounted on the widening plates 1654. Since installing the insert blocks 1652 and limiting blocks 1653 requires a certain amount of space, the widening plates 1654 allow multiple material distribution support platforms 165 to support smaller profiles without interference from the insert blocks 1652 and limiting blocks 1653 on adjacent support plates 1651, preventing the adjacent support plates 1651 from further reducing their distance.

[0057] Please refer to Figure 2 In this embodiment, the punching mechanism 13 includes a punching platform 131, a punching fixed seat 132, a punching movable seat 133, a punching fixture 134, and a clamping assembly 135. The punching fixed seat 132 is disposed on the punching platform 131, the punching movable seat 133 is slidably disposed on the punching platform 131, and punching movable seats 133 are disposed on both sides of the punching fixed seat 132. The punching fixture 134 is disposed between the punching fixed seat 132 and the punching movable seat 133, and the clamping assembly 135 is movably disposed on the upper side of the punching fixture 134.

[0058] The clamping assembly 135 may include a clamping rotating rod and multiple clamping rods connected to the clamping rotating rod. The clamping driving assembly 136 can drive the clamping rotating rod to rotate, thereby causing the multiple clamping rods to clamp or loosen the profile. The clamping driving assembly 136 may consist of a cylinder, a rack connected to the output end of the cylinder, and a gear connected to the clamping rotating rod.

[0059] It should be noted that the punching fixture 134 includes a fixed fixture section and a movable fixture section. The profile is conveyed and placed on the fixed fixture section, and the profile is located between the fixed fixture section and the movable fixture section. At the same time, the clamping assembly 135 clamps the profile on the fixed fixture section. The movable fixture section is provided with a punch, and the punching moving seat 133 slides and presses the movable fixture section, so that the punch punches the profile.

[0060] The working principle of the profile punching device in this embodiment: First, the material distribution and conveying mechanism 16 rises and takes away multiple profiles from the profile cutting device. Then, the variable pitch drive assembly 164 drives multiple material distribution carriers 165 to slide apart by a certain distance. The material distribution and conveying drive assembly 161 drives the material distribution carriers 165 to move and descend, which can transport the profiles to the punching conveying platform 11. The positioning mechanism 15 can push the profiles to position them.

[0061] Then, the punching loading and unloading robot 12 grabs the profile on the punching conveyor platform 11 and conveys it to the punching fixture 134. The pressing component 135 then presses the profile, and the punching moving seat 133 slides and squeezes the punching fixture 134 to complete the punching work on the profile.

[0062] After punching is completed, the punching loading and unloading robot 12 transports the profile on the punching fixture 134 to the flipping gripper 142 located at the flipping receiving position. The flipping gripper 142 can hold the profile and flip and reduce the distance between the two profiles before lowering them onto the riveting conveying platform 21 for riveting processing.

[0063] This completes the punching process and material loading / unloading conveying of the profile punching device in this embodiment.

[0064] In summary, although the present invention has been disclosed above with reference to preferred embodiments, the above preferred embodiments are not intended to limit the present invention. Those skilled in the art can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope defined in the claims.
