[0023] The specific embodiments of the present invention will be described in more detail below with reference to the accompanying drawings, which show representative embodiments of the present invention and are not intended to limit the present invention.

[0024] In manufacturing sheet metal parts for containers, such as beams with C-shaped or U-shaped cross-sections, the current processing method involves single-station, single-machine operation. This lacks continuity under multi-process requirements, leading to production cycle time losses. Furthermore, manual loading, unloading, and positioning processes are susceptible to deviations in processing quality due to unpredictable human factors.

[0025] To at least partially solve the aforementioned problems, this utility model provides a composite automated sheet metal processing robot line for container production, used to produce container sheet metal parts. Container sheet metal parts include door crossbeams, end bottom crossbeams, and base frame bottom crossbeams. This utility model connects four pieces of equipment—a shearing machine 100, a punching machine 101, a deburring machine 102, and a bending machine 103—via a conveyor line and controls them as a whole through a control device, eliminating problems associated with traditional processing methods such as frequent transfers, discontinuous cycle time losses, and unstable quality. Through the coordinated use of the conveyor line and the robotic arms, noise caused by metal workpiece impacts and drops can be eliminated, achieving noise reduction. Furthermore, by incorporating robotic arms, the impact of long-term ground settlement on workpiece transfer between adjacent conveyor lines can be effectively compensated, eliminating the need for leveling the installation surface.

[0026] The following will refer to the figures. Figures 1 to 8 The example shown provides a detailed description of a composite automated line for sheet metal processing robots used in container production according to an embodiment of the present invention.

[0027] The automated composite line for sheet metal processing robots in container production according to an embodiment of the present invention may include a shearing machine 100, a punching machine 101, a deburring machine 102, a bending machine 103, a first flexible conveyor line 104, a first transfer robot 110, a stamping loading robot (not shown), a second transfer robot 130, a third transfer robot 140, a bending conveyor line 105, a bending loading and unloading robot 150, and a control device (not shown). The shearing machine 100, punching machine 101, deburring machine 102, and bending machine 103 are arranged sequentially along the workpiece conveying direction. The workpiece may include a metal sheet to be processed, a semi-finished product, or a target part. The shearing machine 100 is used to receive the metal sheet and cut out a first semi-finished part from the metal sheet. The first semi-finished part may be, for example, a rectangular sheet. The width direction of the sheet is consistent with the output direction of the shearing machine 100. The punching machine 101 is used to punch holes in the first semi-finished part to produce a second semi-finished part. The deburring machine 102 is used to deburr the second semi-finished part to produce the third semi-finished part. The bending machine 103 is used to bend the first semi-finished part and / or the third semi-finished part to produce the target part. The aforementioned shearing machine 100, punching machine 101, deburring machine 102, and bending machine 103 can be existing equipment used for manufacturing sheet metal parts such as container beams.

[0028] The first flexible conveyor line 104 is arranged at its head corresponding to the discharge port of the shear 100. The tail end of the first flexible conveyor line 104 is arranged corresponding to the feed port of the punch press 101. The first flexible conveyor line 104 is used to convey the first semi-finished part to the punch press 101. The first flexible conveyor line 104 can be a belt conveyor line with a PVC conveyor belt. This can reduce the noise when the parts come into contact with the conveyor line.

[0029] The first transfer robot 110 is located between the discharge port of the shear 100 and the beginning of the first flexible conveyor line 104, so as to transfer the first semi-finished part to the first flexible conveyor line 104. Figure 4 As shown, the first transfer robot 110 may include a first transfer suction cup 111, a first transfer lifting assembly 112, and a first transfer longitudinal movement assembly 113. The first transfer longitudinal movement assembly 113 is movably mounted on the frame 10 along the conveying direction of the first flexible conveyor line 104. The first transfer lifting assembly 112 is movably mounted on the first transfer longitudinal movement assembly 113 along the height direction. The height direction is not shown in the accompanying drawings, but those skilled in the art will understand that it refers to the height direction of each device. The first transfer suction cup 111 is mounted on the first transfer lifting assembly 112. The first transfer suction cup 111 is connected to a vacuum device via pipes, solenoid valves, etc. The solenoid valve is controlled by a control device to close or open the air passage. When the solenoid valve is closed, the first transfer suction cup 111 generates suction to hold the first semi-finished part. When the solenoid valve is open, the first transfer suction cup 111 has no suction to release the first semi-finished part.

[0030] A stamping loading robot is located between the tail end of the first flexible conveyor line 104 and the punch press 101 to transfer a first semi-finished part located at the tail end of the first flexible conveyor line 104 to the feed port of the punch press 101. The stamping loading robot may include a stamping loading transfer table (not shown), a stamping loading pusher plate (not shown), and a stamping loading drive unit (not shown). The stamping loading transfer table is located outside the tail end of the first flexible conveyor line 104 along the conveying direction of the first flexible conveyor line 104 and is used to receive the first semi-finished part conveyed by the first flexible conveyor line 104. The stamping loading transfer table is located on one side of the punch press 101 along a transverse direction D2 perpendicular to the conveying direction. The stamping loading pusher plate is movably disposed on the stamping loading transfer table along the transverse direction D2 between a clearance position and a working position. When the stamping loading pusher plate is in the clearance position, it is located at the end of the stamping loading transfer table away from the punch press 101. A stamping feed pusher plate, moving towards the working position, pushes the first semi-finished part toward the press 101. A stamping feed drive unit is connected to the stamping feed pusher plate to drive the stamping feed pusher plate to move in the lateral direction D2. The stamping feed drive unit is a drive unit such as a cylinder that can achieve linear drive.

[0031] The second transfer robot 130 is located between the punch press 101 and the deburring machine 102 to transfer the second semi-finished part from the punch press 101 to the feed end of the deburring machine 102. The second transfer robot 130 may include a second transfer pusher (not shown) and a second transfer drive (not shown). The second transfer pusher is movably disposed on the punch press 101 in a longitudinal direction D1 parallel to the first flexible conveyor line 104. When there is a workpiece on the worktable of the punch press 101, the second transfer pusher is located on the side of the workpiece closer to the shear 100 along the longitudinal direction D1. The second transfer drive is connected to the second transfer pusher and is used to drive the second transfer pusher to move along the longitudinal direction D1 to push the second semi-finished part processed by the punch press 101 toward the deburring machine 102.

[0032] The first end of the bending conveyor 105 is arranged corresponding to the tail end of the first flexible conveyor 104 and the tail end of the second flexible conveyor 108. The tail end of the bending conveyor 105 is arranged corresponding to the feed inlet of the bending machine 103. The bending conveyor 105 is used to convey a third semi-finished part to the bending machine 103. The bending conveyor 105 can be a belt conveyor with a PVC conveyor belt.

[0033] A third transfer robot 140 is positioned between the deburring machine 102 and the bending conveyor line 105 to transfer the third semi-finished part from the discharge end of the deburring machine 102 to the bending conveyor line 105. Figure 6As shown, the third transfer robot 140 may include a receiving component 141, a third transfer pusher plate 142, a third transfer drive component 143, and a tilting drive component 144. The receiving component 141 is arranged longitudinally along the outer side of the deburring machine 102 to receive the third semi-finished part output from the deburring machine 102. The receiving component 141 is located on one side of the bending conveyor line 105 along the transverse direction D2. The third transfer pusher plate 142 is movably connected to the frame 10 in the transverse direction D2. In the initial state, the third transfer pusher plate 142 is located at the end of the receiving component 141 away from or outside the bending conveyor line 105. The third transfer pusher plate 142 is connected to the third transfer drive component 143. The third transfer drive component 143 drives the third transfer pusher plate 142 to translate along the transverse direction D2, pushing the third semi-finished part located above the receiving component 141 onto the bending conveyor line 105. Furthermore, when processing another symmetrical beam-type sheet metal part, the bending direction is opposite to that of the third semi-finished product transported by a flat-push method, for example, changing the upward bend to a downward bend. While the bending processing method of the bending machine 103 remains unchanged, the upper and lower surfaces of the third semi-finished product need to be interchanged. The receiving part 141 has a third transfer suction cup 145. The receiving part 141 is rotatably mounted on the frame 10 between a first working position and a second working position about a flipping axis parallel to the longitudinal direction D1. When the receiving part 141 is in the first working position, it can receive the third semi-finished product from the deburring machine 102. During the flipping process of the receiving part 141 from the first working position to the second working position, the receiving part 141 sucks up the third semi-finished product through the third transfer suction cup 145 and drives the third semi-finished product to flip approximately 180°, so that the orientation of the upper and lower surfaces of the third semi-finished product is interchanged.

[0034] The bending loading / unloading robot 150 is arranged corresponding to the tail end of the bending conveyor 105 and the feed inlet of the bending machine 103, so as to transfer the third semi-finished product or the first semi-finished product from the bending conveyor 105 to the feed inlet of the bending machine 103, and to unload the processed target part. The bending loading / unloading robot 150 is movably arranged relative to the bending conveyor 105 along the transverse direction D2. Figure 8As shown, the bending loading / unloading robot 150 may include a bending station suction cup 151, a bending station lifting assembly 152, and a bending station traversing assembly 153. The bending station traversing assembly 153 is movably mounted on the frame 10 in the lateral direction D2 between the initial position, the bending loading position, and the bending unloading position. The bending station lifting assembly 152 is movably mounted on the bending station traversing assembly 153 in the vertical direction. The bending station suction cup 151 is mounted on the bending station lifting assembly 152. When the bending station traversing assembly 153 is in the initial position, the bending station suction cup 151 is located directly above the bending conveyor line 105. By lifting the bending station suction cup 151 with the bending station lifting assembly 152, it can approach or move away from the bending conveyor line 105. When the bending station lateral movement assembly 153 is in the bending loading position, the bending station suction cup 151 is positioned above the worktable of the bending machine 103. When the bending station lateral movement assembly 153 is in the bending unloading position, the bending station suction cup 151 is positioned above the target unloading position. The bending station suction cup 151 is connected to a vacuum device via pipelines and solenoid valves. The solenoid valve is controlled by a control device to close or open the air passage. When the solenoid valve is closed, the bending station suction cup 151 generates suction to hold the third or first semi-finished part, thereby moving the third or first semi-finished part. When the solenoid valve is open, the bending station suction cup 151 has no suction, allowing the release of the third or first semi-finished part.

[0035] The control device is communicatively connected to the shearing machine 100, punching machine 101, deburring machine 102, bending machine 103, first flexible conveyor line 104, first material transfer robot 110, stamping loading robot, second material transfer robot 130, bending conveyor line 105, third material transfer robot 140, and bending loading / unloading robot 150. The control device can be a PLC, microcontroller, or industrial computer, etc.

[0036] According to an embodiment of the present invention, a composite automatic line for sheet metal processing robots in container production is connected to a shearing machine 100, a punching machine 101, a deburring machine 102, a bending machine 103, a first flexible conveyor line 104, a first transfer robot 110, a stamping loading robot, a second transfer robot 130, a bending conveyor line 105, a third transfer robot 140, and a bending loading and unloading robot 150 via a control device, so as to realize the coordinated operation of each processing equipment, each conveyor line, and each robot. The first semi-finished part is conveyed between the shearing machine 100 and the punching machine 101 by setting up a first flexible conveyor line 104, the third semi-finished part is conveyed between the deburring machine 102 and the bending machine 103 by setting up a bending conveyor line 105, the first semi-finished part manufactured by the shearing machine 100 is transferred to the first flexible conveyor line 104 by setting up a first transfer robot 110, the first semi-finished part is transferred from the first flexible conveyor line 104 to the feed port of the punching machine 101 by setting up a stamping loading robot, the second semi-finished part is transferred from the punching machine 101 to the feed end of the deburring machine 102 by setting up a second transfer robot 130, the third semi-finished part is transferred from the bending conveyor line 105 to the feed port of the bending machine 103 by setting up a third transfer robot 140, and the processed target part is unloaded. By adopting the above-described solution of this utility model, the sequential flow of workpieces in various devices and automatic loading and unloading can be realized, thus achieving continuity in each processing step and improving production efficiency. Furthermore, it can reduce the adverse effects of unstable factors in manual loading and unloading operations on processing quality, thereby improving processing quality.

[0037] See Figure 1 and Figure 4 Optionally, the conveying direction of the first flexible conveyor line 104 is consistent with the discharge direction of the shear 100. Furthermore, the length direction of the first semi-finished part when placed on the punch press 101 must be consistent with the conveying direction of the first flexible conveyor line 104. To this end, the first transfer robot 110 can rotate the first semi-finished part approximately 90° and then transfer it to the first flexible conveyor line 104. The first transfer robot 110 also includes a first transfer rotating assembly 114. The first transfer rotating assembly 114 is mounted on the first transfer lifting assembly 112. A first transfer suction cup 111 is mounted on the first transfer rotating assembly 114. The first transfer rotating assembly 114 can be a rotary cylinder or a motor.

The shearing loading platform 107 is arranged side-by-side with the temporary storage loading platform 106 and aligned with the feed inlet of the shearing machine 100. The first shearing loading robot 160 is used to transfer the metal sheet to be processed from the temporary storage loading platform 106 to the shearing loading platform 107. The first shearing loading robot 160 may include a frame 10, a shearing loading transverse assembly 162, a shearing loading lifting assembly 163, and a shearing loading suction cup 164. The shearing loading transverse assembly 162 is connected to the crossbeam of the frame 10. The shearing loading lifting assembly 163 is connected to the shearing loading transverse assembly 162. The shearing suction cup 164 is connected to the shearing lifting assembly 163. The shearing lateral movement assembly 162 is used to move the shearing suction cup 164 in the lateral direction D2. The shearing lifting assembly 163 is used to move the shearing suction cup 164 in the vertical direction. The shearing suction cup 164 is connected to a vacuum device via pipes, solenoid valves, etc., to grip and release the metal sheet. The second shearing robot 170 is used to transfer the metal sheet to be processed from the shearing loading platform 107 to the shearing machine 100. The second shearing robot 170 includes a shearing longitudinal movement bracket 171, a lead screw and nut assembly 174, a shearing servo motor 172, and a clamping assembly 173. The shearing longitudinal movement bracket 171 is movably mounted on the shearing loading platform 107 along the longitudinal direction D1.

A clamping assembly 173 is installed on the shearing longitudinal support 171 for clamping and releasing the metal plate. The clamping assembly 173 can be a clamp or similar structure. For the same metal plate, the first shearing robot 160 and the second shearing robot 170 move it sequentially. The first shearing robot 160 picks up the metal plate from the temporary loading platform 106, lifts it, moves it laterally, lowers it, and releases it, transferring the metal plate to the shearing loading platform 107. The second shearing robot 170 clamps the metal plate and pushes it towards the shearing machine 100, feeding the metal plate into the shearing machine 100.

The first end of the second flexible conveyor line 108 is arranged side-by-side with the first flexible conveyor line 104. The last end of the second flexible conveyor line 108 extends sequentially with the first end of the bending conveyor line 105. The last end of the second flexible conveyor line 108 is at the same height as the first end of the bending conveyor line 105. This facilitates the movement of the first semi-finished part from the second flexible conveyor line 108 to the bending conveyor line 105. The sorting robot 180 is used to transfer the first semi-finished part from the first flexible conveyor line 104 to the second flexible conveyor line 108 and / or the worktable of the punch press 101. The first flexible conveyor line 104 is closer to the punch press 101 in the transverse direction D2 than the second flexible conveyor line 108. The first semi-finished part entering the worktable of the punch press 101 will be punched by the punch press 101 to produce a second semi-finished part. The first semi-finished part entering the second flexible conveyor line 108 does not need to be punched. It is conveyed to the subsequent bending machine 103 after passing around the punch press 101 on the second flexible conveyor line 108.

[0040] The sorting robot 180 includes a first sorting robot 181 and a second sorting robot 182. The first sorting robot 181 transfers a first semi-finished part from the first flexible conveyor line 104 to the worktable of the punch press 101. The worktable of the punch press 101 is a platform or support table for placing workpieces to be processed. After the first semi-finished part is transferred to the worktable of the punch press 101 by the first sorting robot 181, the first semi-finished part may not be directly below the punch of the punch press 101. In this case, a stamping loading robot is needed to push the first semi-finished part horizontally to directly below the punch. The second sorting robot 182 transfers the first semi-finished part from the first flexible conveyor line 104 to the second flexible conveyor line 108. The height of the second flexible conveyor line 108 can be the same as the height of the first flexible conveyor line 104, thereby facilitating the horizontal transfer of the first semi-finished part by the second sorting robot 182.

[0041] The first sorting robot 181 includes a first sorting support 181a, a first sorting lifting assembly 181b, and a first sorting suction cup 181c. The first sorting support 181a is movably mounted on the frame 10 along the longitudinal direction D1 between the worktable of the first flexible conveyor line 104 and the punch press 101. The first sorting support 181a is driven by a drive component such as a cylinder or an electric cylinder. The first sorting lifting assembly 181b is mounted to the first sorting support 181a. The first sorting suction cup 181c is mounted to the first sorting lifting assembly 181b. The first sorting lifting assembly 181b is used to drive the first sorting suction cup 181c to perform lifting and lowering movements. The first sorting suction cup 181c is connected to a vacuum device via pipes, solenoid valves, etc., for the purpose of suctioning and releasing first semi-finished parts.

[0042] The second sorting robot 182 includes a second sorting support 182a, a second sorting traverse assembly 182b, a second sorting lifting assembly 182c, and a second sorting suction cup 182d. The second sorting support 182a is movably mounted on the frame 10 along the longitudinal direction D1 between the tail end of the first flexible conveyor line 104 and the head end of the second flexible conveyor line 108. The second sorting support 182a is driven by a drive component such as a cylinder or an electric cylinder. The second sorting traverse assembly 182b is mounted to the second sorting support 182a. The second sorting lifting assembly 182c is mounted to the second sorting traverse assembly 182b. The second sorting suction cup 182d is mounted to the second sorting lifting assembly 182c. The second sorting traverse assembly 182b is used to move the second sorting suction cup 182d along the transverse direction D2 between the tail end of the first flexible conveyor line 104 and the head end of the second flexible conveyor line 108. The second sorting lifting assembly 182c is used to drive the second sorting suction cup 182d to move up and down. The second sorting suction cup 182d is connected to a vacuum device through pipelines, solenoid valves, etc., to achieve the suction and release of the first semi-finished product.

[0043] Optionally, the first sorting bracket 181a and the second sorting bracket 182a can be fixed as a single unit. The sorting robot 180 may include a sorting longitudinal movement assembly 183. The sorting longitudinal movement assembly 183 is connected between the assembly of the first sorting bracket 181a and the second sorting bracket 182a and is used to drive the assembly of the first sorting bracket 181a and the second sorting bracket 182a to move longitudinally.

[0044] See Figure 1 and Figure 6 In some embodiments, when processing two sheet metal parts with mirror-like structures, the third transfer robot 140 is also used to flip the third semi-finished part around a flipping axis parallel to the conveying direction, so that the positions of the upper and lower surfaces of the third semi-finished part are interchanged. When processing one of the two mirror-like sheet metal parts, the third transfer robot 140 uses a flat pushing method to transfer the received third semi-finished part to the bending conveyor line 105. When processing the other of the two mirror-like sheet metal parts, the third transfer robot 140 uses a flipping method to transfer the received third semi-finished part to the bending conveyor line 105.

[0045] See Figure 1 and Figure 7In some embodiments, when the bending features at both ends of the sheet metal part in the width direction differ, the embodiments of this application further include a fourth transfer robot 190. The fourth transfer robot 190 is used to rotate the first semi-finished part or the third semi-finished part to reverse their ends. After the ends of the first semi-finished part or the third semi-finished part are reversed, the orientation of the two sides in the width direction of the first semi-finished part or the third semi-finished part is also reversed. The fourth transfer robot 190 includes a fourth transfer lifting assembly 191 and a fourth transfer suction cup 192. The fourth transfer lifting assembly 191 is mounted to the frame 10 and located above the bending conveyor line 105. The fourth transfer suction cup 192 is mounted to the fourth transfer lifting assembly 191. The fourth transfer lifting assembly 191 is used to drive the fourth transfer suction cup 192 to move up and down in the height direction. The fourth transfer suction cup 192 is connected to a vacuum device through pipelines, solenoid valves, etc., to achieve suction and release of the first or third semi-finished part.

[0046] See Figure 1 and Figure 4 In some embodiments, when the horizontal orientation of the first semi-finished part when it is output from the shearing machine 100 is different from the horizontal orientation of the first semi-finished part when it is processed by the punching machine 101, the first transfer robot 110 is also used to rotate the first semi-finished part. For example, the first semi-finished part is rectangular and has a length direction and a width direction. When the first semi-finished part is output from the shearing machine 100, its horizontal orientation is such that its width direction is consistent with the conveying direction of the first flexible conveyor line 104, i.e., the longitudinal direction D1. When the first semi-finished part is processed by the punching machine 101, its horizontal orientation is such that its length direction is consistent with the conveying direction of the first flexible conveyor line 104, i.e., the longitudinal direction D1. Then, after picking up the first semi-finished part, the first transfer robot 110 first rotates the first semi-finished part by about 90°, and then places it on the first flexible conveyor line 104. Accordingly, the first transfer robot 110 also includes a first transfer rotation assembly 114. The first material transfer rotating assembly 114 is connected between the first material transfer suction cup 111 and the first material transfer lifting assembly 112 to drive the first material transfer suction cup 111 to rotate. The first material transfer rotating assembly 114 may be, for example, a rotary cylinder, a motor, etc.

[0047] See Figure 1In some embodiments, the automated composite line for sheet metal processing robots used in container production according to this embodiment further includes a shearing machine discharge conveyor line 109. The shearing machine discharge conveyor line 109 is located between the discharge port of the shearing machine 100 and the first flexible conveyor line 104, and is used to receive the first semi-finished part and convey it to the first flexible conveyor line 104. This allows for continuous conveying of the first semi-finished part unloaded from the shearing machine 100, preventing the first semi-finished part from accumulating, bumping, or falling, thereby protecting the first semi-finished part and reducing noise. The shearing machine discharge conveyor line 109 can be a belt conveyor line with a PVC conveyor belt, which further helps to reduce noise.

[0048] Furthermore, the first end of the first flexible conveyor line 104 is higher than the tail end of the shearing machine discharge conveyor line 109. The first material transfer robot 110 can effectively adapt to application scenarios where there is a height difference between the first flexible conveyor line 104 and the shearing machine discharge conveyor line 109.

[0049] Continue reading Figure 1 Optionally, a stop 109a can be provided at the end of the shearing machine discharge conveyor line 109. The stop 109a is used to block the first semi-finished part to prevent it from falling from the end of the shearing machine discharge conveyor line 109 and causing damage to the first semi-finished part, noise, or other problems.

[0050] See also Figure 1 In some embodiments, the automated sheet metal processing robot line for container production also includes a buffer unloading conveyor 201. At least a portion of the buffer unloading conveyor 201 is arranged corresponding to the bending machine 103. The buffer unloading conveyor 201 can be a belt conveyor with a PVC conveyor belt. The bending loading / unloading robot 150 is used to transfer the target parts from the bending machine 103 to the buffer unloading conveyor 201. The buffer unloading conveyor 201 is used to alleviate the palletizing cycle time before the palletizing station, preventing the finished products from accumulating and bumping. At the end or a part in the middle of the buffer unloading conveyor 201, palletizing can be performed manually or by a palletizing robot 204.

[0051] See also Figure 1 In some embodiments, the automated sheet metal processing robot line for container production also includes a palletizing conveyor line 202. An operator or palletizing robot 204 can palletize finished products on the palletizing conveyor line 202 for transport. The palletizing conveyor line 202 can be a belt conveyor line with a PVC conveyor belt.

[0052] See also Figure 1In some embodiments, the automated sheet metal processing robot line for container production also includes a flipping frame 203. The palletizing robot 204 can first place the finished products from the buffer discharge conveyor 201 onto the flipping frame 203, and then pick up / grab the finished products on the flipping frame 203 again, thereby enabling the finished products to be palletized in more postures, thus improving the flexibility of palletizing.

[0053] See also Figure 1 In some embodiments, the automated sheet metal processing robot composite line for container production according to this embodiment further includes a palletizing robot 204. The palletizing robot 204 is located between the end of the buffer unloading conveyor line 201 and the palletizing conveyor line 202, and is used to transfer and palletize target parts located on the buffer unloading conveyor line 201 to the palletizing conveyor line 202. Optionally, the palletizing robot 204 can be a six-axis palletizing robot 204, which, for example, has six rotational degrees of freedom, and can be a palletizing robot 204 in the prior art. The palletizing robot 204 can also be other palletizing robots 204 or robotic arms in the prior art besides the six-axis palletizing robot 204.

[0054] See Figure 1 and Figure 7In some embodiments, the automated sheet metal processing robot line for container production according to this embodiment further includes a semi-finished product loading platform 205 and a fourth transfer robot 190. The semi-finished product loading platform 205 is located beside the bending conveyor line 105 and is used to place the first or third semi-finished product to be processed. The fourth transfer robot 190 is used to transfer the first or third semi-finished product from the semi-finished product loading platform 205 to the bending conveyor line 105. When the shearing of some sheet metal parts cannot be performed by the shearing machine 100 on the automated line, or the punching process cannot be performed by the punching machine 101 on the automated line, they can be processed first by other suitable shearing machines 100 or punching machines 101 before being placed on the semi-finished product loading platform 205 for automatic loading, conveying, unloading, and stacking by the automated line. The fourth transfer lifting assembly 191 of the fourth transfer robot 190 can have two different strokes in driving the fourth transfer suction cup 192 to lift, to accommodate the height difference between the semi-finished product loading platform 205 and the bending conveyor line 105. The fourth transfer robot 190 may also have a fourth transfer traversing assembly 193. The fourth transfer traversing assembly 193 is connected to the frame 10. The fourth transfer lifting assembly 191 is mounted to the fourth transfer traversing assembly 193. The fourth transfer suction cup 192 is mounted to the fourth transfer lifting assembly 191. The fourth transfer traversing assembly 193 is used to move the fourth transfer lifting assembly 191 and the fourth transfer suction cup 192 in the lateral direction D2 between the semi-finished product loading platform 205 and the bending conveyor line 105. The fourth transfer lifting assembly 191 then drives the fourth transfer suction cup 192 to move up and down, thus approaching and moving away from the semi-finished product loading platform 205 and the bending conveyor line 105. By setting up a semi-finished product loading platform 205 and cooperating with the fourth transfer robot 190, the flexible production needs of similar parts with the same process but different sizes can be met.

[0055] See Figure 1 and Figure 8In some embodiments, the bending machine 103 can perform bending processing on two parts simultaneously. In this embodiment, the bending conveyor line 105 includes a first bending conveyor line 105a and a second bending conveyor line 105b arranged sequentially along the conveying direction. The first bending conveyor line 105a is located upstream of the second bending conveyor line 105b. The first bending conveyor line 105a may be longer than the second bending conveyor line 105b. The second bending conveyor line 105b can hold a first semi-finished part or a third semi-finished part to be processed. The first bending conveyor line 105a and the second bending conveyor line 105b can be controlled independently. After the part on the second bending conveyor line 105b is moved into place, the second bending conveyor line 105b can be stopped while the first bending conveyor line 105a continues to convey the part to be processed. This allows the part to be transported to another processing station parallel to the part on the second bending conveyor line 105b. Then, the bending loading and unloading robot 150 simultaneously transfers the parts to be processed on the first bending conveyor line 105a and the second bending conveyor line 105b to the processing platform of the bending machine 103 for bending processing.

[0056] See Figure 8 Furthermore, the bending machine 103 is also equipped with a transverse positioning assembly 210 and a longitudinal positioning assembly 220. The bending machine 103 has an upper bending die and a lower bending die. The lower bending die is fixed. The upper bending die can move up and down relative to the lower bending die to perform bending processing on the workpiece to be processed placed on the lower bending die. The transverse positioning assembly 210 is located on the side of the lower bending die away from the bending conveyor line 105 along the transverse direction D2, and is used to position the transverse position of the workpiece to be processed. The transverse positioning assembly 210 may include a transverse positioning plate and a transverse drive cylinder. The transverse drive cylinder is connected to the transverse positioning plate to drive the transverse positioning plate to move in the transverse direction D2, and can move to the transverse positioning position and the reverse push unloading position. In the transverse positioning position, the transverse positioning plate can position the transverse position of the workpiece to be processed. In the reverse push unloading position, the transverse positioning plate can push the processed workpiece away from the lower bending die. A pair of longitudinal positioning assemblies 220 may be provided. A pair of longitudinal positioning components 220 are disposed opposite to each other on both sides of the lower bending die to position the workpiece in the longitudinal direction. Each longitudinal positioning component 220 may include a longitudinal positioning plate and a longitudinal drive cylinder. The longitudinal drive cylinder is connected to the longitudinal positioning plate to move the longitudinal positioning plate between a longitudinal clearance position and a longitudinal positioning position. In the longitudinal clearance position, the workpiece can be moved into and out of the bending machine 103. In the longitudinal positioning position, the longitudinal positioning plate positions the workpiece at a position D1 in the longitudinal direction.

[0057] In the embodiments of this application, the lifting components such as the first material transfer lifting assembly 112, the bending station lifting assembly 152, the shearing bed loading lifting assembly 163, the first sorting lifting assembly 181b, the second sorting lifting assembly 182c, and the fourth material transfer lifting assembly 191 may include a lifting base, a lifting component, and a lifting cylinder. The lifting component is slidably mounted on the lifting base along the height direction via a guide rail slider structure. A portion of the lifting cylinder is fixed to the lifting base, and the other portion is connected to the lifting component. When the lifting cylinder is working, it can drive the lifting component to move up and down. It is understood that the lifting cylinder can be replaced by a screw and nut mechanism and a motor, etc., which can achieve the corresponding function. It is also understood that although the specification of this embodiment does not show the complete structure of each lifting assembly, those skilled in the art can implement it based on the devices / components disclosed in the prior art that can achieve the function of the lifting components of this utility model.

[0058] In the embodiments of this application, the longitudinal transfer components, such as the first transfer longitudinal transfer assembly 113 and the sorting longitudinal transfer assembly 183, may include a longitudinal transfer base, a longitudinal transfer member, and a longitudinal transfer cylinder. The longitudinal transfer member is slidably mounted on the longitudinal transfer base along the longitudinal direction D1 via a guide rail slider structure. A portion of the longitudinal transfer cylinder is fixed to the longitudinal transfer base, and the other portion is connected to the longitudinal transfer member. When the longitudinal transfer cylinder is working, it can drive the longitudinal transfer member to move along the longitudinal direction D1. It is understood that the longitudinal transfer cylinder can be replaced by a drive component capable of achieving the corresponding function, such as a lead screw and nut mechanism and a motor. More importantly, although the specification of this embodiment does not show the complete structure of each longitudinal transfer component, those skilled in the art can implement it based on the devices / components disclosed in the prior art that can achieve the function of the longitudinal transfer components of this utility model.

[0059] In the embodiments of this application, the transverse movement components such as the bending station transverse movement component 153, the shearing bed loading transverse movement component 162, the second sorting transverse movement component 182b, and the fourth transfer transverse movement component 193 may include a transverse movement base, a transverse movement member, and a transverse movement cylinder. The transverse movement member is slidably mounted on the transverse movement base along the transverse direction D2 via a guide rail slider structure. A portion of the transverse movement cylinder is fixed to the transverse movement base, and the other portion is connected to the transverse movement member. When the transverse movement cylinder is working, it can drive the transverse movement member to move along the transverse direction D2. It is understood that the transverse movement cylinder can be replaced by a drive component capable of achieving the corresponding function, such as a lead screw and nut mechanism and a motor. It is also understood that although the specification of this embodiment does not show the complete structure of each transverse movement component, those skilled in the art can implement it based on the devices / components disclosed in the prior art that can achieve the function of the transverse movement components of this utility model.

[0060] In the embodiments of this application, the rotating assemblies, such as the first material transfer rotating assembly 114 and the fourth material transfer rotating assembly 194, may include a rotating base, a rotating component, and a rotating cylinder. The rotating component is rotatably mounted on the rotating base. A portion of the rotating cylinder is fixed to the rotating base, and another portion is connected to the rotating component. When the rotating cylinder is working, it can drive the rotating component to rotate. Optionally, the rotating assembly may omit the rotating base and the rotating component, and only use a rotating cylinder. It is also understood that although the specification of this embodiment does not show the complete structure of each rotating assembly, those skilled in the art can implement it based on prior art devices / components capable of realizing the function of the rotating assembly of this utility model.

[0061] See Figures 1 to 8 This invention provides a composite automated sheet metal processing robot line for container manufacturing, connecting four pieces of equipment—a shearing machine, a punch press (101), a deburring machine, and a bending machine (103)—via a conveyor line and controlling them as a whole through a control device. This invention solves the problems of low efficiency, frequent transfer processes, and unstable quality in single-machine processing of sheet metal parts for containers, while eliminating noise caused by metal impacts during material discharge. Furthermore, by using a conveyor belt to transport workpieces and a robotic arm to transfer workpieces between adjacent conveyor belts and between the conveyor belt and the equipment, it helps prevent belt damage caused by materials falling freely onto the conveyor belt. Application results of this composite automated sheet metal processing robot line for container manufacturing in production practice show that it can improve material transfer efficiency and parts processing cycle time, reduce production noise, and improve processing quality.

[0062] See also Figures 1 to 8In this embodiment of the invention, after the metal sheet to be processed is placed on the shearing and feeding platform 107, the clamping assembly 173 is controlled to clamp the metal sheet, and the shearing servo motor 172 drives the shearing longitudinal support 171 to move forward, thereby feeding the metal sheet onto the shearing machine 100. Limiting mechanisms and position sensors can be combined to ensure the metal sheet accurately reaches the processing station. After the current station's process is completed, each robot arm realizes the flow of the workpiece between the conveyor line and the equipment's worktable, between adjacent conveyor lines, and between equipment, successively performing stamping, deburring, bending, and other processing steps, or skipping stamping and deburring processes to proceed directly to bending and other processing steps. Optionally, two or more magnetic switches are set at each processing station to ensure accurate positioning of the parts, and combined with the cooperative use of PVC conveyor belts and robots, the noise source of metal impact is eliminated, achieving a low-noise target. For symmetrical parts, the control device, in conjunction with position sensors, counts the material. When the required processing quantity is reached, the robot arm automatically rotates and reverses direction, and the flipping robot arm flips the material. At the final bending station, the bending conveyor line 105 is divided into two independent conveyor lines: a first bending conveyor line 105a and a second bending conveyor line 105b. The second bending conveyor line 105b serves as a buffer for the conveying cycle, balancing the processing cycle of each process. Furthermore, regarding the discharge from the bending machine 103, a buffer discharge conveyor line 201 is installed to alleviate and balance the production cycle of unloading, material transfer, and palletizing. At the end of the buffer discharge conveyor line 201, a weighing sensor can be installed to confirm whether the buffer quantity meets the transfer conditions to the next station. Simultaneously, a camera can be installed to record the processing process, ensuring that any abnormalities can be traced back to the previous stage.

[0063] According to an embodiment of this utility model, the process of processing sheet metal parts using a composite automatic line for container production sheet metal processing robots can be as follows: After placing steel plates or other metal sheets on a loading platform, a shearing robot grabs and moves them, then the loading platform carries the steel plates into the shearing machine 100 for cutting. During the cutting and output process, the number of processed parts is counted. When processing symmetrical parts, based on preset quantity conditions, after reaching the required quantity in a certain direction, the robot automatically rotates and reverses direction to process the symmetrical parts. The punching machine 101 then picks up the parts and rotates them to place them on the first flexible conveyor line 104, moving forward and entering the punching machine 101's feeding position. At this point, a sorting robot 180 determines whether the part requires punching. If punching is required, it enters the punching machine 101. If punching is not required, it is pushed into the second flexible conveyor line 108. After the punched parts are processed by the punch press 101, they enter the deburring machine 102 for grinding. After sorting or processing at the punch press 101 station, the parts enter the bending conveyor line 105 and are driven forward to the feeding position of the bending machine 103. The bending loading and unloading robot 150 puts in and takes out the parts (depending on the part requirements, up to two products can be processed at the same time). After the parts are processed, they are taken out and placed on the buffer discharge conveyor line 201 and driven to the discharge positioning position. In order to balance the processing cycle of each process, a buffer area is set up at the discharge position, and the buffer amount is confirmed by the weighing sensor to confirm whether the buffer amount meets the conditions for the next transfer.
