Description

Technical Field

[0001] This invention relates to the field of automated production technology, and more specifically, to a special latch box for electric vehicle doors and an automated cutting production equipment. Background Technology

[0002] Electric vehicle door latch box is an accessory used in electric vehicle door lock systems; it is used to install and fix the latching device. During the production of the latch box, it is cut by a laser tube cutting machine. The tube to be processed is placed on the worktable of the cutting machine by a feeding device. Before the cutting begins, the laser tube cutting machine is usually equipped with a sensor or vision system. The operator inputs the cutting parameters and path on the controller according to the cutting requirements. The laser generator of the cutting machine starts to work, generating a high-energy laser beam. The laser beam is focused on the surface of the tube by an optical system, generating high temperature, which melts or vaporizes the tube material instantly. The laser cutting head moves according to the preset cutting path under the drive of the machine tool. The cutting head is usually mounted on a multi-axis robotic arm or moving platform, which can move flexibly in three-dimensional space to achieve complex cutting of the tube. After the cutting is completed, the cut tube is removed from the worktable by a feeding device. A search revealed that CN113210896A discloses a tube cutting and unloading transportation mechanism for a laser tube cutting machine, including a laser tube cutting mechanism. Two adjustable unloading plates are located on both sides of the front end of the laser tube cutting mechanism. The bottoms of the two adjustable unloading plates are hinged together by hinges. A main lifting mechanism is located directly below the hinge of the two adjustable unloading plates. The lifting rod of the main lifting mechanism is mounted on the hinge. This device can adjust the central main lifting mechanism to move upwards, while the two auxiliary lifting mechanisms on both sides move downwards, allowing the outer ends of the unloading plates on both sides to be placed on the transport vehicles on both sides. Then, the central main lifting mechanism is raised, causing the internal tubes to roll off from both sides onto the transport vehicles.

[0003] The electric vehicle door latch box is formed by cutting rectangular tubes. During the cutting process, the cut section of the tube is suspended in the air. When the end of the tube rotates, the slight swaying of the tube under the action of gravity will cause the cutting trajectory to deviate from the predetermined path, resulting in a serrated or irregular shape. Furthermore, when the laser beam cuts the tube, the heat will cause the tube to expand locally. The expanded part may change the cutting direction, resulting in an uneven laser-cut surface. Based on this, the present invention discloses an electric vehicle door latch box and an automated cutting production equipment. Summary of the Invention

[0004] To address the issues raised in the background art, during the cutting process, the pipe segment is suspended in the air, and the slight swaying of the pipe end under gravity during rotation causes the cutting trajectory to deviate from the predetermined path, resulting in serrated or irregular shapes.

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Therefore, such as Figure 1 As shown, the present invention provides a special buckle box for electric vehicle doors, including a rectangular tube 1. A notch 2 is provided on one side of the rectangular tube 1. The notch 2 is a rectangular opening. The special buckle box for electric vehicle doors is an accessory for electric vehicle door lock systems, used to install and fix the buckle device. The shell of the buckle box is cut and formed from the rectangular tube 1, and a notch 2 is provided on one end of the rectangular tube 1. It is integrally formed into a special buckle box for electric vehicle doors.

[0020] like Figure 2 , Figure 3 As shown, the present invention provides an automated cutting production equipment for electric vehicle door buckle boxes, used to produce the electric vehicle door buckle boxes as described in claim 1, including a second support frame 14, on which a cutting structure 10 is assembled, the cutting structure 10 being used to cut and shape the buckle box; like Figure 2 As shown, a first support frame 12 is installed on one side of the second support frame 14, and a bearing structure 13 is installed on the first support frame 12. The bearing structure 13 is used to support and lift the pipe. like Figure 6 , Figure 7 As shown, the bearing structure 13 includes a rotating cylinder 131. A rod hole is provided on the cylinder wall of the rotating cylinder 131, and a movable rod 135 is slidably inserted into the rod hole. One end of the movable rod 135 is fixed with a limit cap 134, which is located outside the rotating cylinder 131. A spring 133 is sleeved on the top of the movable rod 135. One end of the spring 133 is fixed on the limit cap 134, and the other end of the spring 133 is fixed outside the rotating cylinder 131. The other end of the movable rod 135 is fixed with a second roller frame 136, which is located inside the rotating cylinder 131. A guide wheel 1314 is rotatably installed inside the second roller frame 136. A guide plate 132 is fixed on one side of the second roller frame 136. The bottom of the guide plate 132 has an arc-shaped structure, and the bottom of the guide plate 132 is set in close contact with the guide wheel 1314. The rotating cylinder 131 has four guide wheels 1314 and a guide plate 132 arranged in a cross shape inside. The bending area of ​​the guide plate 132 bends from one end of the rotating cylinder 131 toward the guide wheel 1314. When cutting and shaping the buckle box, continuous cutting is achieved through laser cutting. However, due to the limitations of the existing operation mode, there is no support part in the cutting part. During the cutting process, the pipe will shake due to its own weight and other factors, resulting in a serrated or irregular shape, which makes it impossible to meet the cutting accuracy requirements. The pipe may also undergo local deformation during the cutting process, resulting in an uneven cut surface. To ensure the stability of the tube during laser cutting, after the tube is fed out through the clamping and guiding structure 9, the end of the tube is identified and calibrated. After calibration, a notch 2 is cut on the side of the end of the rectangular tube 1. After the notch 2 is cut, one end of the tube continues to extend. During the extension process, the tube is inserted into the rotating cylinder 131 of the bearing structure 13. like Figure 6 As shown, guide plates 132 are arranged in a cross shape inside the rotating cylinder 131. As one end of the pipe gradually extends into the rotating cylinder 131, the pipe, guided and constrained by the curved surfaces of the guide plates 132, can enter the center of the rotating cylinder 131. After the pipe penetrates deep into the rotating cylinder 131, guide wheels 1314 located in four directions roll and contact the four outer surfaces of the pipe. After the pipe extends into the rotating cylinder 131, since the guide wheels 1314 all move outwards, during the outward movement of the guide wheels 1314, the pipe is guided by the second roller frame 136... The combination allows the movable rod 135 to slide in different rod holes. Under the action of the limit cap 134, the spring 133 is stretched, causing the spring 133 to generate a contraction force. Under the action of the contraction force of the spring 133, the guide wheel 1314 can press and restrain the tube, thereby supporting and restraining the tube extending during the cutting process. The restraint in the four directions of the four guide wheels 1314 can achieve the support and restraint of the tube, avoiding swaying due to gravity and the appearance of sawtooth or irregular shapes, making the cutting more precise.

[0021] like Figure 7 As shown, the bearing structure 13 also includes two third support frames 1316. The third support frames 1316 are both vertically fixed on the first support frame 12. The third support frames 1316 are located on both sides of the rotating cylinder 131. The upper and lower ends of the opposite surfaces of the third support frames 1316 are fixed with third roller frames 1317. The third roller frames 1317 are rotatably equipped with constraint rollers 1318. A first limiting ring 1313 and a second limiting ring 1315 are respectively fixed on the outer wall of the rotating cylinder 131. The constraint roller 1318 is rotatably disposed between the first limiting ring 1313 and the second limiting ring 1315, and the circumferential surface of the constraint roller 1318 rolls and fits against the circumferential surface of the rotating cylinder 131.

[0022] During operation, when laser cutting the pipe, the pipe needs to rotate to achieve the cutting operation. In order to support the rotation of the pipe, the guide wheel 1314 can constrain the pipe in four directions under the contraction thrust of the four directional springs 133. When the pipe is being cut by rotation, the rotating cylinder 131 can rotate synchronously. A third support frame 1316 is symmetrically arranged on both sides of the rotating cylinder 131. Rotatable constraint rollers 1318 are installed on the upper and lower sides of the third support frame 1316, which can provide rotational support for the rotating cylinder 131. During the cutting process, the rotation of the rotating cylinder 131 can follow the rotation of the pipe synchronously. During the rotation, the second roller frame 136 in four different directions can continuously provide support for the pipe, which can reduce the irregular shaking of the cutting section due to gravity and improve the accuracy of cutting.

[0023] like Figure 7 As shown, the other end of the rotating cylinder 131 is provided with a transverse insertion hole, which is perpendicular to the rod hole through which the movable rod 135 slides, and a clamping rod 1319 is inserted into the transverse insertion hole. The top of the first support frame 12 is fixed with a guide rail 1312, and a support plate 1311 is slidably mounted on the guide rail 1312. A bearing outer ring 139 is fixed on the support plate 1311, and a bearing inner ring 137 is rotatably disposed inside the bearing outer ring 139. Bearing balls 138 are assembled between the bearing inner ring 137 and the bearing outer ring 139. One end of the clamping rod 1319 is fixed on the bearing inner ring 137. A third cylinder 1310 is mounted on the top of the first support frame 12, and the telescopic end of the third cylinder 1310 is fixed to one side of the support plate 1311.

[0024] During operation, to reduce the swaying of the cut section caused by gravity during pipe cutting, the contraction reaction force of spring 133 is used to generate an effective clamping force on the pipe by the guide wheel 1314 in the corresponding position. Since the reaction force is provided by spring 133, spring 133 will also vibrate itself. To reduce vibration during pipe rotation and cutting, after the cut section is stably constrained by the four guide wheels 1314, the extension movement of the third cylinder 1310 can push the support plate 1311 to slide on the guide rail 1312, causing the outer ring 139 of the bearing to... Approaching the rotating cylinder 131, as the outer ring 139 of the bearing moves, the inner ring 137 of the bearing moves synchronously with the outer ring 139. After the inner ring 137 moves, it pushes the clamping rod 1319 into the transverse insertion hole. The end of the clamping rod 1319 abuts against the middle section of the limiting cap 134, which can prevent the limiting cap 134 from sliding during the rotational cutting process. This ensures that the positions of the guide wheels 1314 in the four directions do not change during the rotational cutting of the pipe, thus ensuring the stability of the support and lifting of the pipe, ensuring accurate cutting lines, and improving cutting accuracy.

[0025] like Figure 5 As shown, a cutting structure 10 is installed on the second support frame 14. The cutting structure 10 includes a transverse sliding plate 105. A transverse sliding hole 104 for sliding the transverse sliding plate 105 is opened in the top crossbeam of the second support frame 14. A second cylinder 103 is installed on the top of the transverse sliding plate 105. The telescopic end of the second cylinder 103 passes through the transverse sliding plate 105. A laser cutting machine 106 is connected to the bottom of the second cylinder 103. A cutting head 107 is fitted to the bottom of the laser cutting machine 106. A first connecting plate 102 is fixed on the top of the transverse sliding plate 105. A first cylinder 101 is installed transversely on the top crossbeam of the second support frame 14. The telescopic rod end of the first cylinder 101 is fixed to one side of the first connecting plate 102. During operation, the extension and retraction of the first cylinder 101 and the second cylinder 103 are accurately controlled through programming. During the cutting process, as the pipe moves, the first cylinder 101 pushes the first connecting plate 102 through the accurate stroke of the first cylinder 101 and the second cylinder 103, realizing the lateral movement of the transverse sliding plate 105 within the transverse sliding hole 104, thus realizing the lateral movement of the laser cutting machine 106. During the movement of the second cylinder 103, the laser cutting machine 106 moves vertically, and the cutting head 107 performs the cutting operation on the pipe.

[0026] like Figure 4 , Figure 8 , Figure 9As shown, a feeding bed 3 is provided on one side of the second support frame 14. A clamping and guiding structure 9 is installed on the top of one end of the feeding bed 3. The clamping and guiding structure 9 includes a second fixing plate 91. The second fixing plate 91 is fixed to the top of one end of the feeding bed 3. A rotating hollow shaft 99 is rotatably assembled inside the second fixing plate 91. A second rotating disk 98 is fixed to one end of the rotating hollow shaft 99. A second guide rail 96 is provided in a cross direction on the end face of the second rotating disk 98. A second guide rail 96 is slidably assembled inside the second guide rail 96. The second slider 95 has a first locking screw hole inside, and a second locking screw 92 is threaded into the first locking screw hole of the second slider 95. The second locking screw 92 is used to lock and fix the second slider 95. A first support connecting rod 94 is fixed on the second slider 95. A first roller frame 93 is installed on the first support connecting rod 94. A guide roller 97 is rotatably installed in the first roller frame 93. The four guide rollers 97 are divided into a horizontal pair and a vertical pair, and the two pairs of guide rollers 97 are staggered front and rear. During operation, when guiding the pipe, the pipe passes through the central hole in the second rotating disk 98. The second rotating disk 98 has four second guide rails 96 in four directions, and the four second guide rails 96 are respectively slidably mounted on the four second guide rails 96. During the sliding of the second sliders 95, the positions of the four guide rollers 97 can be adjusted. Under the constraint of the four guide rollers 97, a rectangular constraint can be formed on the pipe. The guide rollers 97 can rotate, and under the constraint of the four guide rollers 97, the rotation of the guide rollers 97 can ensure accurate delivery of the pipe.

[0027] like Figure 9 As shown, a drive motor 911 is assembled in the cavity of the second fixed plate 91, and a gear ring 910 is fixed on the outer wall of the rotating hollow shaft 99. The gear ring 910 meshes with the drive gear 912. During operation, the drive motor 911 operates, driving the drive gear 912 to rotate. With the transmission cooperation of the gear ring 910, it can drive the rotating hollow shaft 99. With the rotation cooperation of the rotating hollow shaft 99, it can drive the second rotating disk 98 to rotate. During the rotation, the pipe is cut.

[0028] like Figure 4As shown, two guide rods 8 are fixed in parallel inside the feeding bed 3. A sliding seat 7 is slidably mounted on the guide rod 8. A screw hole is opened in the middle of the sliding seat 7. A feeding motor 4 is installed on one side of the feeding bed 3. A lead screw 6 is rotatably installed inside the feeding bed 3. The lead screw 6 is arranged parallel to the guide rods 8. One end of the lead screw 6 is connected to the output shaft of the feeding motor 4 through a coupling. The lead screw 6 rotates through the screw hole in the sliding seat 7 through a threaded engagement. During operation, when pushing and conveying materials, one end of the pipe is placed through the pipe hole limited by four guide rollers 97, and the other end of the pipe is clamped and fixed on the clamping and feeding structure 5. When conveying the pipe longitudinally, the feeding motor 4 drives the lead screw 6 to rotate, which pushes the sliding seat 7 to slide along the guide rod 8 under the threaded engagement, thus realizing the longitudinal conveying of the pipe. During the cutting process of the notch 2 of the buckle box, the forward and reverse rotation of the feeding motor 4 is alternated to realize the longitudinal extension and retraction of the pipe. According to the programmed control of the operation of the feeding motor 4, the forward and reverse rotation of the lead screw 6 is adjusted to accurately control the movement position of the sliding seat 7, so as to achieve accurate cutting of the notch 2 and realize the conveying of the pipe. like Figure 10 As shown, a clamping and feeding structure 5 is fixed on the sliding seat 7. The clamping and feeding structure 5 includes a first fixing plate 51, which is mounted on the sliding seat 7. A first rotating disk 56 is rotatably assembled inside the first fixing plate 51.

The first locking screw 52 is used for locking and positioning the first slider 54. A clamping plate 53 is installed on the first slider 54. During operation, when the pipe is being fed and clamped, the sliding seat 7 moves to move the clamping and feeding structure 5. When fixing the other end of the pipe, the first rotating disk 56 has first guide rails 55 in four directions, and the first sliding block 54 is set in the first guide rails 55. With the cooperation of the clamping plates 53 in four directions, the rectangular pipe can be fixed. When the pipe rotates, the first rotating disk 56 can rotate with the second rotating disk 98. After the other end of the pipe is fixed, the sliding seat 7 moves to deliver the pipe accurately according to the program.

[0029] The cutting structure 10 is installed between the clamping and feeding structure 5 and the bearing structure 13. The rotating cylinder 131 and the second rotating disk 98 and the first rotating disk 56 of the bearing structure 13 are coaxial. A controller 11 is installed on one side wall of the second support frame 14. The controller 11 is used for the control of the electrical structure. During operation, when cutting the pipe, the rotating cylinder 131, the second rotating disk 98 and the first rotating disk 56 are set as a coaxial structure, which can ensure that the pipe rotates synchronously and coaxially during the cutting process, ensure the synchronization of feeding, cutting and support, ensure that the pipe is a stable parallel structure during the cutting process, and ensure the accuracy of cutting. By setting preset programming through controller 11, the stroke process of each electric structure is accurately written into the data to ensure accurate coordination of each electrical component during the laser cutting process, and to ensure accurate and continuous cutting and forming of the buckle box.

[0030] Working principle: When cutting and shaping the snap box, laser cutting is used to achieve the cutting and shaping of the snap box. During the cutting process, the controller 11 sets the preset program and accurately writes the stroke process of each electric structure to ensure the accurate coordination of each electric device during the laser cutting process, and ensure the accurate and continuous cutting and shaping of the snap box. During pipe feeding, the pipe passes through the central hole in the second rotating disk 98. The second rotating disk 98 has four second guide rails 96 in four directions. The four second guide rails 96 are each slidably mounted on a second slider 95. During the sliding of the second slider 95, the position of the four guide rollers 97 can be adjusted. Under the constraint of the four guide rollers 97, a rectangular constraint can be formed on the pipe. The guide rollers 97 can rotate. During pipe feeding, under the constraint of the four guide rollers 97 and in conjunction with the rotation of the guide rollers 97, the pipe can be accurately conveyed. When the pipe is being fed and clamped, the movement of the sliding seat 7 enables the movement of the clamping and feeding structure 5. When fixing one end of the pipe, the first guide slide rail 55 is provided in four directions on the first rotating disk 56, and the first sliding block 54 is provided in the first guide slide rail 55. With the cooperation of the clamping plates 53 in four directions, the rectangular pipe can be fixed. When the pipe is rotated, the first rotating disk 56 can rotate with the second rotating disk 98. After fixing one end of the pipe, the movement of the sliding seat 7 enables the accurate delivery of the pipe according to the program. During the cutting process, the drive motor 911 operates, driving the drive gear 912 to rotate. With the transmission cooperation of the gear ring 910, it can drive the rotating hollow shaft 99. With the rotation cooperation of the rotating hollow shaft 99, it can drive the second rotating disk 98 to rotate. During the rotation, the pipe is cut. During the feeding and conveying process, one end of the pipe is placed through the pipe hole limited by four guide rollers 97, and the other end of the pipe is clamped and fixed on the clamping and feeding structure 5. When the pipe is conveyed longitudinally, the feeding motor 4 drives the lead screw 6 to rotate, which pushes the sliding seat 7 to slide along the guide rod 8 under the threaded engagement, thus realizing the longitudinal conveying of the pipe. During the cutting process of the notch 2 of the buckle box, the pipe is moved longitudinally by alternating forward and reverse rotation of the feeding motor 4. According to the programmed control of the operation of the feeding motor 4, the forward and reverse rotation of the lead screw 6 is adjusted to accurately control the movement position of the sliding seat 7, so as to achieve accurate cutting of the notch 2 and realize the conveying of the pipe. During cutting, the extension and retraction of the first cylinder 101 and the second cylinder 103 are accurately controlled through programming. During the cutting process, as the pipe moves, the first cylinder 101 pushes the first connecting plate 102 through the accurate stroke of the first cylinder 101 and the second cylinder 103, so that the transverse sliding plate 105 moves laterally within the transverse sliding hole 104, realizing the transverse movement of the laser cutting machine 106. During the movement of the second cylinder 103, the laser cutting machine 106 moves vertically, and the cutting head 107 performs the cutting operation on the pipe. To ensure the stability of the tube during laser cutting, after the tube is fed out through the clamping and guiding structure 9, the end of the tube is identified and calibrated. After calibration, a notch 2 is cut on the side of the end of the rectangular tube 1. After the notch 2 is cut, one end of the tube continues to extend. During the extension process, the tube is inserted into the rotating cylinder 131 of the bearing structure 13. Inside the rotating cylinder 131, guide plates 132 are arranged in a cross pattern. As one end of the pipe gradually penetrates into the rotating cylinder 131, the pipe, guided and constrained by the curved surfaces of the guide plates 132, can enter the center of the rotating cylinder 131. After the pipe penetrates the rotating cylinder 131, guide wheels 1314 located in four directions roll and contact the four outer surfaces of the pipe. After the pipe extends into the rotating cylinder 131, since the guide wheels 1314 all move outward, during the outward movement of the guide wheels 1314, the pipe is guided by the second roller frame 136. The mechanism allows the movable rod 135 to slide in different rod holes. Under the action of the limit cap 134, the spring 133 is stretched, causing the spring 133 to generate a contraction force. Under the action of the contraction force of the spring 133, the guide wheel 1314 can press and restrain the tube, thus supporting and restraining the tube extending during the cutting process. The constraint in the four directions of the four guide wheels 1314 can support and restrain the tube, preventing swaying due to gravity and the appearance of sawtooth or irregular shapes, making the cutting more precise. When laser cutting a pipe, the pipe needs to be rotated to perform the cutting operation. In order to support the rotation of the pipe, the guide wheel 1314 can constrain the pipe in four directions under the contraction thrust of the four directional springs 133. When the pipe is being cut by rotation, the rotating cylinder 131 can rotate synchronously. A third support frame 1316 is symmetrically arranged on both sides of the rotating cylinder 131. Rotatable constraint rollers 1318 are installed on the upper and lower sides of the third support frame 1316, which can provide rotational support for the rotating cylinder 131. During the cutting process, the rotation of the rotating cylinder 131 can follow the pipe and rotate synchronously. During the rotation, the second roller frame 136 in four different directions can continuously provide support for the pipe, which can reduce the irregular swaying of the cutting section due to gravity and improve the accuracy of cutting. During pipe cutting, to reduce the swaying of the cut segment caused by gravity, the contraction reaction force of spring 133 is used to enable the guide wheel 1314 in the corresponding position to generate an effective clamping force on the pipe. Since the reaction force is provided by spring 133, spring 133 will also vibrate itself. To reduce vibration during pipe rotation and cutting, after the cut segment is stably constrained by the four guide wheels 1314, the extension movement of the third cylinder 1310 can push the support plate 1311 to slide on the guide rail 1312, causing the outer ring of the bearing 139 to approach... When the outer ring 139 of the bearing moves, the inner ring 137 of the bearing moves synchronously with the outer ring 139 of the bearing. After the inner ring 137 of the bearing moves, it pushes the clamping rod 1319 into the transverse insertion hole. The end of the clamping rod 1319 abuts against the middle section of the limiting cap 134, which can prevent the limiting cap 134 from sliding during the rotational cutting process. It can ensure that the position of the guide wheels 1314 in the four directions does not change during the rotational cutting of the pipe, which can ensure the stability of the support and lifting of the pipe, ensure the accuracy of the cutting line, and improve the cutting accuracy.
