[0002] With the further expansion and promotion of new energy vehicles as a new trend in the development of automotive industry technology, the anti-collision beams used in new energy vehicles are designed to cooperate with the vehicle's anti-collision design to absorb and disperse energy in the event of a collision and protect the lives of drivers and passengers.

[0003] The anti-collision beams of new energy vehicles are basically aluminum products. Aluminum anti-collision beams are composed of aluminum profiles, energy absorption boxes, and automobile connecting plates. In the production of aluminum anti-collision beams, it is usually necessary to complete the preliminary preparations for the production of aluminum anti-collision beams through processes such as batch loading and cut-to-size sawing.

[0004] At present, the sawing of aluminum anti-collision beams is basically done manually, that is, the packaging is manually unpacked, the aluminum profiles in the whole package are separated one by one, they are manually transported and loaded one by one, sawed one by one, and then picked up and stacked into the material basket manually. The production efficiency is low, and it is difficult to ensure the consistency of the aluminum profile loading benchmark, the consistency of the aluminum profile sawing size, and the integration of the loading process, sawing process and logistics process.

[0005] It can be seen that the shortcomings of the existing technology are: manual operation is inefficient, it is difficult to ensure the consistency of the feeding benchmark, it is difficult to ensure the consistency of the aluminum profile sawing size, it is easy to cause product surface scratches, saw cut deformation, size failure, etc., resulting in waste, which directly leads to unnecessary material loss. When the aluminum alloy profile packaging is unpacked, the traceability function cannot be realized, which will lead to system material mismatch, and there will be missed scanning and missing records. Summary of the invention

[0006] In view of this, the present invention aims to propose an automatic sizing sawing device for anti-collision beam profiles, which can accurately control the lifting height, conveying speed and conveying position of a whole package of aluminum profiles used to manufacture anti-collision beams through a profile feeding mechanism, a profile logistics roller and a servo feeding assembly according to different process flows and process requirements.

The continuous automated production of anti-collision beam profiles is realized through the servo feeding assembly, automatic sawing by the aluminum profile saw, and synchronous grabbing and stacking by the material unloading and stacking robot.

[0009] In some embodiments, the aluminum profile saw includes a profile saw frame structure, a special saw blade driven by a variable frequency sawing motor, a movable sawing assembly driven by a sawing slide cylinder, a profile fixing mechanism consisting of a clamping cylinder and a pressure plate, and an aluminum chip conveyor.

DETAILED DESCRIPTION

[0030] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0031] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings and in combination with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Reference below Figures 1 to 9 The automatic sizing and sawing device for anti-collision beam profiles according to the embodiment of the present invention is described in conjunction with the embodiments.

[0033] The invention discloses an automatic sizing sawing device for anti-collision beam profiles, which is equipped with a robot control system, a hydraulic station, and a wind pressure and electric control system.

[0034] like Figure 1 , Figure 2 , Figure 3 As shown, the device mainly includes: an aluminum profile saw 1, a material unloading and stacking robot 2, a profile logistics roller 3, a servo feeding component 4, a profile loading mechanism 5, an aluminum alloy profile 6, a piano-type operating cabinet 7, a safety guardrail 8, and a logistics transfer vehicle 9.

[0035] The aluminum profile saw 1 is specially designed and manufactured for cutting aluminum alloy profiles to a fixed length during the production of anti-collision beams. The aluminum profile saw 1 is installed at one end of the profile logistics roller 3. A sawing operation panel 102 is installed on the aluminum profile saw 1 to facilitate the operator to set the servo feeding distance, saw blade rotation speed, sawing rhythm, and fixed length. The sawing position of the aluminum profile can be confirmed more intuitively. By adjusting the sawing speed, feed amount and other parameters on the operation panel, the sawing process can be smoother, the generation of waste can be reduced, and the accuracy and work efficiency of profile sawing can be improved.

[0036] While the variable frequency sawing motor 104 installed on the sawing component mounting plate 121 is driven by the sawing slide cylinder 114 to slide forward, the special saw blade 103 rotates at high speed, and the sawing inner and outer clamping cylinders 117 and the sawing inner clamping cylinder 120 respectively drive the sawing outer vertical pressure plate 116 and the sawing inner vertical pressure plate 119 to cooperate with each other, and the aluminum alloy profile 6 is directly sawed into aluminum profile blocks 207.

[0037] The unloading and stacking robot 2 is installed at the lower end of the aluminum profile saw 1. The arm span of the unloading and stacking robot 2 covers the silo outlet of the aluminum profile saw 1 and the logistics transfer vehicle 9. The unloading and stacking robot 2 is equipped with a robot gripper ( Figure 8 ) is used to accurately grab the aluminum profile blocks 207 that have been cut to size and realize the sorting and stacking of the aluminum profile blocks 207. The logistics transfer vehicle 9 quickly moves the stacked aluminum profile blocks 207 to the subsequent production process of the anti-collision beam assembly line to achieve a good connection between the various processes ( Fig. 9 ).

[0038] The profile logistics roller 3 is fixed on the ground through a plurality of logistics roller legs 301, and the profile logistics roller 3 is also equipped with a diagonal long rack 304, a linear guide rail I 302, a linear guide rail II 303 and a servo feeding assembly 4. A servo feeding assembly 4 is also installed on the profile logistics roller 3.

[0039] The servo feeding assembly 4 enables the aluminum alloy profile 6 to enter the aluminum profile saw 1 accurately without causing jamming, tilting, collision, etc. due to height difference or position deviation, and can ensure the continuity and stability of the aluminum alloy profile 6 on the profile logistics roller 3. It is convenient to achieve precise docking in the automated production process and reduce the time for manual intervention and adjustment. No additional positioning or correction operations are required, so the conveying speed can be increased, the transmission time of the aluminum alloy profile 6 between each link can be shortened, and the operation efficiency of the entire production system can be improved, and the production efficiency can be improved.

[0040] The servo feeding assembly 4 is equipped with a servo motor and a bevel gear meshing with a bevel long rack, and a guide rail slider matched with a linear guide rail. The rotation of the servo motor drives the bevel gear to rotate, so that the servo feeding assembly 4 moves smoothly along the linear guide rail, which is used for the precise feeding and conveying of the aluminum alloy profile 6 with a fixed size, and provides high-quality technical support for the automatic fixed-length sawing device of the anti-collision beam profile to achieve fixed-length sawing.

[0041] The profile feeding mechanism 5 is fixed on the ground, and the profile feeding mechanism 5 is composed of a set of active crawler feeding devices and two sets of driven crawler feeding devices. The two sets of driven crawler feeding devices adopt a symmetrical mirroring method of mechanical structure and are respectively installed on both sides of the active crawler feeding device. The installation position of the profile feeding mechanism 5 is perpendicular to the overall direction of the profile logistics roller 3 and maintains a horizontal state. This vertical installation method makes it easy for the profile feeding mechanism 5 to move the aluminum alloy profile 6 horizontally, so that the aluminum alloy profile 6 can be transferred and transported as a whole without unbundling the whole package. Ensure the precise positioning and movement of the aluminum alloy profile 6 in the vertical direction, effectively cooperate with the process flow of automatic sizing and sawing of anti-collision beam profiles, and improve the automation level and production efficiency of automatic sizing and sawing of anti-collision beam profiles.

[0042] The profile feeding mechanism 5 uses a multi-machine linkage mode through multiple couplings and connecting shafts. It can better, more stably and more reasonably share the weight of the aluminum alloy profiles 6 with a standard length of 6 meters, 4 layers, 4 groups, and a total of 16 aluminum alloy profiles 6, or aluminum alloy profiles 6 with longer size or heavier weight and more layers and groups, prevent the aluminum alloy profiles 6 from tilting or deforming during horizontal movement, and ensure the smoothness and safety of the profile feeding operation.

[0043] The piano-type operating cabinet 7 is equipped with operation buttons such as start, stop, reset, emergency stop, and a touch screen human-machine screen, which can set the hydraulic station pressure and stroke curve. It can display various operating parameters and operating status of the equipment in real time, display the robot's movement speed, joint angle, equipment operation record, aluminum alloy profile 6 material consumption and other production data.

[0044] Safety nets 8 are installed outside the aluminum profile saw 1, the unloading and stacking robot 2, the profile logistics roller 3, and the profile loading mechanism 5. The lifting operation area is separated from other areas, and the dangerous area is clearly divided to remind the surrounding personnel not to enter at will, which is helpful to regulate the order of the operation site and reduce the risk of irrelevant personnel entering the dangerous area.

[0045] like Figure 4 As shown, the profile feeding mechanism 5 is composed of a set of active crawler feeding devices and two sets of driven crawler feeding devices. The two sets of driven crawler feeding devices are installed on both sides of the active crawler feeding device in a symmetrical mirroring manner of mechanical structure. The two sets of driven crawler feeding devices are completely identical in shape, structure, layout and function. Among them, the left driven crawler feeding device is connected to the left universal coupling 508 of the active crawler feeding device through the left connecting shaft 509, and the left driven crawler feeding device is connected to the right universal joint 511 of the active crawler feeding device through the right connecting shaft 511.

[0046] The active crawler loading device of the profile loading mechanism 5 mainly includes: a loading device support leg 501, a loading platform 502, an active motor 503, an active sprocket 504, a transmission chain 505, a transmission sprocket 506, a crawler structure 507, a left universal joint 508, a left connecting shaft 509, a right universal joint 510, and a right transmission shaft 511.

[0047] The driven crawler loading device on the left side of the loading device leg fixes the frame loading device leg 501 to the ground with a plurality of anchor adjustment bolts, and keeps the loading device leg 501 level by adjusting the anchor adjustment bolts.

[0048] The loading platform 502 is fixed to the upper end of the loading device leg 501 by high-strength bolts, and the track structure 507 is fixed to the upper end of the loading platform 502 by a plurality of support brackets and high-strength bolt connection. The left frame and the rear right frame of the track structure 507 are connected by a track driven gear and a track driving gear to form a frame structure. An annular track is installed between the track driven gear and the track driving gear. A left universal coupling 508 is installed at one end of the track driving gear, and a transmission sprocket 506 and a right universal coupling 510 are installed at the other end.

[0049] When the driving motor 503 rotates, it drives the driving sprocket 504, the transmission chain 505, and the transmission sprocket 506 to rotate together. The rotation of the transmission sprocket 506 drives the track driving gear connected thereto to rotate synchronously, and the rotation of the track driving gear drives the annular track and the track driven gear to rotate together. At the same time, the transmission sprocket 506 drives the left universal coupling 508, the left connecting shaft 509, the right universal coupling 510, and the right transmission shaft 511 connected thereto to drive the left driven track loading device and the right driven track loading device to rotate synchronously.

[0050] A plurality of deep groove bearings are installed on each crawler driving gear and crawler driven gear, and these deep groove bearings play the role of reducing friction and providing support. The crawler structure 507 is structurally stable and strong, and can withstand large loads and impacts. It can also maintain excellent performance under high load and high-speed movement, and has a long service life and high working reliability. At the same time, this combination of three sets of crawler feeding devices can maintain the overall stability and load-bearing capacity of the profile feeding mechanism 5.

[0051] The left universal coupling 508 and the right universal coupling 510 are mainly composed of two U-shaped forks and a cross shaft. The U-shaped forks are connected to the active shaft and the driven shaft respectively, and the cross shaft is installed between the two U-shaped forks. Even if the drive shafts of the driven track loading device and the active track loading device are not concentric during the equipment construction and installation process, when there is an axial angle between the left connecting shaft 509 and the right transmission shaft 511, the universal joint can change the transmission angle within a certain range to adapt to the angle change between the two shafts. The movement and torque of the transmission sprocket 506 can be reliably transmitted to the left connecting shaft 509 and the right transmission shaft 511, realizing the continuous rotation of the two shafts, and realizing the synchronous rotation of the left and right driven track loading devices and the active track loading device.

[0052] The insertion ports of the left universal coupling 508 and the right universal coupling 510 are designed with card slots, which are used together with anti-retraction plates to effectively ensure the stability of the transmission shaft connection during the movement of the left connecting shaft 509 and the right transmission shaft 511, prevent the transmission shaft from accidentally falling off, and avoid safety accidents.

[0053] A friction torque limiter is also designed on the transmission sprocket 506, which can control the load torque of the transmission sprocket 506 within the design range. When the load of the transmission sprocket 506 suddenly increases due to mechanical failure of the transmission sprocket 506 or failure of the two sets of driven crawler feeding devices, causing the required torque to exceed the set value of the friction torque limiter, it will limit the torque transmitted by the transmission system in the form of slipping, which can effectively prevent the transmission sprocket 506, the transmission chain 505, the driving sprocket 504, the crawler driving gear and other transmission components from being subjected to excessive torque and causing structural damage, prevent the driving motor 503 from being overloaded and burned, and avoid equipment failure or safety accidents, thereby reducing maintenance costs and downtime.

[0054] like Figure 5 As shown, the servo feeding assembly 4 mainly includes: a feeding platform 401, four guide rail sliders 402, a servo motor 403, a helical gear 404, a feeding horizontal frame 405, a feeding horizontal push plate 406, a feeding horizontal cylinder 407, a feeding vertical frame 408, a feeding vertical pressure plate 409, and a feeding vertical cylinder 410.

[0055] The feeding horizontal frame 405 is installed horizontally on the feeding platform 401, and the feeding horizontal push plate 406 passes through four guide sleeves of the feeding horizontal frame 405 through four horizontal guide rods and is installed inside the feeding horizontal frame 405. The feeding horizontal cylinder 407 is fixed to the outside of the feeding horizontal frame 406 by bolts, and the cylinder rod of the feeding horizontal cylinder 407 is connected to the feeding horizontal push plate 406. The extension and retraction of the cylinder rod of the feeding horizontal cylinder 407 drives the feeding horizontal push plate 406 to move forward and backward along the four horizontal guide rods.

[0056] The feeding vertical frame 408 is installed on the feeding platform 401 in a vertical direction, and the feeding vertical pressing plate 409 passes through four guide sleeves of the feeding vertical frame 408 through four vertical guide rods and is installed inside the feeding vertical frame 408. The feeding vertical cylinder 410 is fixed to the outside of the feeding vertical frame 408 by bolts, and the cylinder rod of the feeding vertical cylinder 410 is connected to the feeding horizontal push plate 406. The extension and retraction of the cylinder rod of the feeding vertical cylinder 410 drives the feeding vertical pressing plate 409 to move up and down along the four vertical guide rods.

[0057] The motor shaft of the servo motor 403 is connected with a reducer. The servo motor 403 and the reducer are installed on the feeding platform 401. The output shaft end of the reducer is installed with a helical gear 404, which meshes with the helical long rack 304 installed on the profile logistics roller 3. Four guide rail sliders 402 are also installed under the feeding platform 401, of which two guide rail sliders on one side cooperate with the I linear guide 302, and two guide rail sliders on the other side cooperate with the II linear guide 303. The servo motor 403 rotates, and the helical gear 404 is driven to rotate through the reducer, and further drives the feeding platform 401 and the feeding horizontal push plate 406, the feeding horizontal frame 405, the feeding horizontal cylinder 407, the feeding vertical frame 408, the feeding vertical pressure plate 409, and the feeding vertical cylinder 410 to move forward and backward along the I linear guide 302 and the II linear guide 303.

[0058] like Figure 6 , Figure 7 As shown, the aluminum profile saw 1 mainly includes: a profile saw frame structure 101, a sawing operation panel 102, a special saw blade 103, a variable frequency sawing motor 104, a motor base 105, a base slide 106, an outer slider 107, 4 shock-absorbing bolts 108, an inner slider 109, an outer guide rail 110, an inner guide rail 111, I spring buffer 112, II spring buffer 113 (not shown), a sawing slide cylinder 114, a sawing outer vertical frame 115, a sawing outer vertical pressure plate 116, a sawing outer clamping cylinder 117, a sawing inner vertical frame 118, a sawing inner vertical pressure plate 119, a sawing inner clamping cylinder 120, a sawing component mounting plate 121, and an aluminum chip conveyor 122.

[0059] The profile saw frame structure 101 is fixed on the ground and connected to the profile logistics roller 3. The sawing operation panel 102 is fixed on the profile saw frame structure 101 to facilitate the operator to set the servo feeding distance, saw blade rotation speed, sawing rhythm, and fixed length. It can more intuitively confirm the sawing position of the aluminum profile. By adjusting the sawing speed, feed rate and other parameters on the operation panel, the sawing process is smoother, the generation of waste is reduced, and the accuracy and work efficiency of profile sawing are improved.

[0060] The aluminum chip conveyor 122 is fixed on the back of the profile saw frame structure 101, and an aluminum chip trolley is placed under the aluminum chip conveyor 122 to minimize the splashing and scattering of aluminum chips during the falling process, improve the aluminum chip collection efficiency, keep the working area clean, and facilitate aluminum chip recycling.

[0061] The sawing assembly mounting plate 121 is fixed on the profile saw frame structure 101 , and the sawing assembly mounting plate 121 is installed with an outer guide rail 110 , an inner guide rail 111 , and a spring buffer I 112 and a spring buffer II 113 for buffering the movement inertia of the base slide 106 .

[0062] The variable frequency sawing motor 104 of the aluminum profile saw 1 is mounted on a motor base 105, and the motor base 105 is mounted on a base slide 106 through four shock-absorbing bolts 108. Two outer sliders 107 and two inner sliders 109 are mounted below the base slide 106. The two outer sliders 107 cooperate with the outer guide rails 110, and the two inner sliders 109 cooperate with the inner guide rails 111.

[0063] The sawing slide oil cylinder 114 is installed on the sawing assembly mounting plate 121. The top of the cylinder rod of the sawing slide oil cylinder 114 is connected to the base slide 106 through a movable joint and an L-shaped connector. The extension and retraction of the cylinder rod of the sawing slide oil cylinder 114 drive the lower base slide 106 and the outer slider 107 and the inner slider 109 to move forward and backward along the outer guide rail 110 and the inner guide rail 111. The cylinder body of the sawing slide oil cylinder 114 is installed with a detection switch to detect whether the cylinder rod of the sawing slide oil cylinder 114 is extended or retracted into place.

[0064] A long groove is provided on the sawing assembly mounting plate 121 to facilitate the movement of the special saw blade 103. The sawing outer vertical frame 115 and the sawing inner vertical frame 118 are respectively close to the long groove and installed on both sides of the long groove in a vertical direction. The sawing outer vertical pressure plate 116 passes through the four guide sleeves of the sawing outer vertical frame 115 through four vertical guide rods and is installed inside the sawing outer vertical frame 115. The sawing outer clamping cylinder 117 is fixed to the outside of the sawing outer vertical frame 115 by bolts, and the cylinder rod of the sawing outer clamping cylinder 117 is connected to the sawing outer vertical pressure plate 116. The extension and retraction of the cylinder rod of the sawing outer clamping cylinder 117 drives the sawing outer vertical pressure plate 116 to move up and down along the four vertical guide rods.

[0065] The sawing inner vertical pressing plate 119 passes through four guide sleeves of the sawing inner vertical frame 118 through four vertical guide rods and is installed inside the sawing inner vertical frame 118. The sawing inner pressing cylinder 120 is fixed to the outside of the sawing inner vertical frame 118 by bolts, and the cylinder rod of the sawing inner pressing cylinder 120 is connected to the sawing inner vertical pressing plate 119. The extension and retraction of the cylinder rod of the sawing inner pressing cylinder 120 drives the sawing inner vertical pressing plate 119 to move up and down along the four vertical guide rods.

[0066] The special saw blade 103 is a specially customized saw blade with a large diameter, which completely covers the sawing of the outer vertical frame 115 and the inner vertical frame 118, and is used to cut the whole package of aluminum alloy aluminum materials (the aluminum alloy profile 6 does not need to be disassembled and unpacked) for efficient mass production. The material of this saw blade is a special alloy with extremely high hardness and excellent durability, and can maintain good cutting accuracy and efficiency.

[0067] The motor base 105 provides a stable installation foundation and support for the special saw blade 103. The four shock-absorbing bolts 108 can effectively absorb and disperse the impact energy generated by the special saw blade 103 and the variable frequency sawing motor 104 during the sawing of aluminum alloy profiles, which can better ensure the vertical feed angle of the special saw blade 103, and can better suppress the impact and vibration of the special saw blade 103 during load sawing, ensuring that the special saw blade 103 remains stable during high-speed rotation and sawing, preventing shaking, deviation, etc., so as to ensure the accuracy and safety of sawing.

[0068] like Figure 8 As shown, the robot gripper mainly includes: a connecting flange 201, a flange support 202, a gripper main beam 203, a longitudinal partition 204, a gripper cylinder 205, a T-shaped hinge connecting plate 206, and an aluminum profile block 207.

[0069] The flange support 202 is installed at the center of the gripper main beam 203 by bolts, and the connecting flange 201 is installed on the flange support 202. The connecting flange 201 is connected to the sixth axis of the unloading and stacking robot 2 by multiple bolts. The pipelines and detection switch cables of multiple gripper cylinders 205 pass through the connecting flange 201, the flange support 202, and the center circular hole of the gripper main beam 203 to connect with the control system of the unloading and stacking robot 2. The center circular holes of the connecting flange 201, the flange support 202, and the gripper main beam 203 are concentric.

[0070] The five longitudinal partitions 204 are fixed to the gripper main beam 203 by multiple bolts. The five longitudinal partitions 204 are equidistant from each other. At both ends of each longitudinal partition 204, gripper cylinders 205 are symmetrically installed, and at both sides of each gripper cylinder 205, T-shaped hinge connecting plates 206 are installed.

[0071] The piston of the gripper cylinder 205 moves, changing the relative position of the hinge connecting rod of the T-shaped hinge connecting plate 206, accurately limiting the displacement of the aluminum profile block 207, and generating a greater output force through the lever effect of the connecting rod and the change in the geometric shape of the hinge connecting rod. The force-increasing effect of the T-shaped hinge connecting plate significantly improves the carrying capacity of the robot gripper. The piston of the gripper cylinder 205 can grab 10 aluminum profile blocks 207 at a time.

[0072] Here, the robot gripper is distributed in a symmetrical mirroring manner of mechanical structure, and one side of the gripper main beam 203 is completely identical to the other side in terms of shape, structure, position and function. Such a connection method can increase the complexity and redundancy of the structure, improve the deformation resistance and bearing capacity of the structure, adapt to different load distributions, and effectively transfer and disperse the load. It is convenient for the robot gripper to grasp, transport and turn over the aluminum profile block 207, thereby improving production efficiency.

[0073] like Fig. 9 As shown, the logistics transfer vehicle 9 is a manual cart that can be loaded with multiple aluminum profile blocks 207. The storage bin of the logistics transfer vehicle 9 is consistent with the position of the robot gripper of the unloading and stacking robot 2, ensuring that the robot gripper can accurately grab the aluminum profile blocks 207 and directly put them into the storage bin of the logistics transfer vehicle 9, thereby improving the unloading efficiency, reducing the risk of misalignment, reducing the probability of grasping failure, reducing the positioning and adjustment time of the unloading and stacking robot 2, shortening the unloading cycle, and ensuring the stability of automated production and transportation.

[0074] The logistics transfer vehicle 9 is also equipped with a long handle and four wheels with steering function, which can be used to carry multiple aluminum profile blocks 207 over a short distance. It is convenient to quickly move more aluminum profile blocks to the subsequent production process of the anti-collision beam assembly line in the anti-collision beam production workshop at one time, thereby improving the logistics handling and transportation efficiency.

[0075] Thus, the device is suitable for the automatic cut-to-length sawing device for anti-collision beam profiles. First, the pressure of the hydraulic station, the stroke curve, and the movement speed and joint angle of the robot are set through the touch screen window of the piano-type operating cabinet 7. The servo feeding distance, the saw blade rotation speed, the sawing beat, and the cut-to-length length are set through the sawing operation panel 102.

[0076] The profile feeding mechanism 5 on the profile logistics roller 3 is at one end of the logistics roller. The aluminum alloy profile 6 does not need to be disassembled and unpacked. The operator scans the code of the package, and the batch number of the aluminum alloy profile 6 will be entered into the system to achieve the traceability function. Then the whole package of aluminum alloy profile 6 is hoisted and placed on the profile feeding mechanism 5. The worker exits the safety range of the safety guardrail 8 and presses the start button of the piano-type operating cabinet 7.

[0077] The active motor 503 of the profile feeding mechanism 5 rotates, driving the crawler structure 507 to rotate through the transmission sprocket 506, and at the same time driving the left driven crawler feeding device and the right driven crawler feeding device to rotate synchronously through the left universal coupling 508, the left connecting shaft 509, the right universal coupling 510, and the right transmission shaft 511 connected thereto, so as to transfer the whole package of aluminum alloy profiles 6 to the profile logistics roller 3.

[0078] Next, the cylinder rod of the horizontal feeding cylinder 407 of the servo feeding assembly 4 retracts, driving the horizontal feeding push plate 406 to move backward along the four horizontal guide rods, and the cylinder rod of the vertical feeding cylinder 410 retracts, driving the vertical feeding pressing plate 409 to move upward along the four vertical guide rods. The servo motor 403 rotates, driving the feeding platform 401 to move forward. The aluminum alloy profile 6 enters the interior of the horizontal feeding frame 405. The cylinder rod of the vertical feeding cylinder 410 extends, driving the vertical feeding pressing plate 409 to move downward along the four vertical guide rods, pressing the aluminum alloy profile 6 to keep it still. The servo motor 403 rotates, driving the feeding platform 401 and the aluminum alloy profile 6 to move forward and enter the interior of the aluminum profile saw 1.

[0079] The cylinder rod of the sawing outer clamping cylinder 117 retracts, driving the sawing outer vertical pressing plate 116 to move upward along the four vertical guide rods. The cylinder rod of the sawing inner clamping cylinder 120 retracts, driving the sawing inner vertical pressing plate 119 to move upward along the four vertical guide rods. The servo motor 403 continues to rotate, further driving the feeding platform 401 and the aluminum alloy profile 6 to move forward into the sawing outer vertical frame 115 and the sawing inner vertical frame 118. At this time, the cylinder rod of the sawing outer clamping cylinder 117 extends, driving the sawing outer vertical pressing plate 116 to move downward along the four vertical guide rods. The cylinder rod of the sawing inner clamping cylinder 120 extends, driving the sawing inner vertical pressing plate 119 to move downward along the four vertical guide rods. The two inner and outer clamping cylinders tightly press the aluminum alloy profile 6 to keep it still. The extension of the cylinder rod of the sawing slide oil cylinder 114 drives the lower base slide 106 and the motor base 105 to move forward. At the same time, the variable frequency sawing motor 104 drives the special saw blade 103 to rotate at high speed, and directly saws the aluminum alloy profile 6 into aluminum profile blocks 207.

[0080] The electronic control system of the equipment detects the pressure and stroke curve of the hydraulic station, and the detection switch of the cylinder body of the sawing slide oil cylinder 114 detects whether the oil cylinder rod has advanced to the right position. After the electronic control system detects the signal, it will proceed to the next action, otherwise the equipment alarm action will be suspended.

[0081] After the loading action is completed, the variable frequency sawing motor 104 stops rotating, and the rod of the sawing slide oil cylinder 114 retracts. The detection switch of the sawing slide oil cylinder 114 cylinder body detects whether the oil cylinder rod has retreated to the right position. After the electronic control system detects the signal, the cylinder rod of the sawing outer clamping cylinder 117 retracts, driving the sawing outer vertical pressing plate 116 to move upward along the four vertical guide rods. The cylinder rod of the sawing inner clamping cylinder 120 retracts, driving the sawing inner vertical pressing plate 119 to move upward along the four vertical guide rods.

[0082] The robot gripper on the unloading and stacking robot 2 moves to accurately grab the aluminum profile blocks 207 that have been cut to a fixed length and directly put them into the storage bin of the logistics transfer vehicle 9 to achieve sorting and stacking.

[0083] The servo motor 403 continues to rotate again, driving the feeding platform 401 and the aluminum alloy profile 6 to move forward into the sawing outer vertical frame 115 and the sawing inner vertical frame 118. The aluminum profile saw 1 performs a circular sawing operation again, and continues to gradually saw the remaining aluminum alloy profile 6 into aluminum profile blocks 207.

[0084] As the aluminum alloy profile 6 is gradually sawed and becomes shorter, the cylinder rod of the feeding vertical cylinder 410 retracts again, driving the feeding vertical pressure plate 409 to move upward along the four vertical guide rods, and the cylinder rod of the feeding horizontal cylinder 407 extends, driving the feeding horizontal push plate 406 to move forward along the four horizontal guide rods, pushing all the remaining aluminum alloy profiles 6 into the sawing outer vertical frame 115 and the sawing inner vertical frame 118, completing the last sawing, until all the remaining aluminum alloy profiles 6 are sawn into aluminum profile blocks 207.

[0085] The robot gripper on the unloading and stacking robot 2 moves until the storage bin of the logistics transfer vehicle 9 is full, and the logistics transfer vehicle 9 quickly moves the stacked aluminum profile blocks 207 to the subsequent production process on the anti-collision beam assembly line.

[0086] In some embodiments, an automatic sizing sawing device for anti-collision beam profiles includes: an aluminum profile saw, a material unloading and stacking robot, a profile logistics roller, a servo feeding assembly, a profile loading mechanism, an aluminum alloy profile, a piano-type operating cabinet, a safety guardrail, a logistics transfer vehicle, etc.

[0087] Among them, the aluminum profile saw adopts the "rigid-flexible coupling" design concept, mainly including: the profile saw frame structure used for the basic support of the entire system. The sawing operation panel is used to facilitate the operator to set the servo feeding distance, saw blade rotation speed, sawing beat, cut length, and adjust the sawing speed, feed amount and other parameters. The special saw blade can better suppress the impact and vibration of the saw blade during load sawing to ensure a better vertical feed angle. The variable frequency sawing motor can ensure that the special saw blade remains stable during high-speed rotation and sawing to prevent shaking, offset and other situations. To ensure the sawing accuracy and the safety of the motor base and base slide, the guide rails, sliders and sawing slide cylinders that move stably. The shock-absorbing bolts that can effectively absorb and disperse the impact energy generated during the sawing of aluminum alloy profiles, and the spring buffers used to buffer the inertia of the base slide movement. Used for sawing internal and external vertical frames, sawing internal and external vertical pressure plates, and sawing internal and external clamping cylinders. And aluminum chip conveyors and aluminum chip trolleys are used to reduce the splash and scattering of aluminum chips and improve the efficiency of aluminum chip collection.

[0088] The unloading and stacking robot is installed at the lower end of the aluminum profile saw. The robot gripper of the unloading and stacking robot accurately grabs the aluminum profile blocks that have been cut to size, sorts and stacks them on the logistics transfer vehicle, and quickly moves them to the subsequent production processes on the anti-collision beam assembly line, achieving a good connection between the various processes.

[0089] The servo feeding assembly 4 uses the servo motor 403 and the bevel gear meshing with the bevel long rack to make the aluminum alloy profile move smoothly along the slider and guide rail, and accurately transport it into the aluminum profile saw, so as to realize the fixed length sawing of the anti-collision beam profile automatic fixed length sawing device, providing high-quality technical support.

[0090] The profile feeding mechanism uses multiple couplings and connecting shafts, multi-machine linkage mode, and universal joint connection to simplify installation and construction. It can adapt to the angle change between the two shafts when there is an axis angle between the two shafts, and can reliably transmit torque to achieve continuous rotation of the two shafts, so as to achieve synchronous rotation of the left and right sets of driven crawler feeding devices and the active crawler feeding device.

[0091] The transmission sprocket is also designed with a friction torque limiter, which can control the load torque of the transmission sprocket within the design range, effectively preventing the transmission components from being damaged due to excessive torque, avoiding equipment failure or safety accidents, and thus reducing maintenance costs and downtime.

[0092] For the proposed technical solution, there are alternative solutions, such as using a hydraulic station and a hydraulic cylinder to replace the sawing external clamping cylinder 117, the sawing internal clamping cylinder 120, the feeding horizontal cylinder 407, the feeding vertical cylinder 410, and the sawing slide cylinder 114 as pressure cylinders, using other forms of profile transplanting mechanisms to replace the profile loading mechanism 5, using other forms of material step feeding methods to replace the servo feeding component 4, using other forms of robots or grippers to replace the unloading and stacking robot 2, and using other forms of sawing methods to replace the aluminum profile saw 1, etc., all of which are within the protection scope of the present invention.

Automatic loading of anti-collision beam profiles is realized and the profile batch number is entered into the system, so that the logistics of batch profiles can be traced. Thereby solving the practical production problems such as low efficiency of manual handling, feeding and sawing one by one, and then manual picking, missing code scanning, missing records, poor consistency of production line profile products, high scrap rate such as saw edge deformation and unqualified size, and inability to realize profile product traceability function. It not only improves the efficiency and automation of material transportation, but also reduces the intensity of manual labor, avoids errors and safety risks caused by manual operation, and can realize intelligent control of the entire process of sawing and cutting of anti-collision beam profiles.
