Description

Technical Field

[0001] The present invention belongs to the technical field of buckle processing, and specifically relates to an integrated equipment for buckle riveting and detection. Background Art

[0002] With the development of the economy, automobiles have become a means of transportation for people's daily use, and the demand is relatively large. The automobile door lock system is an important component to ensure the safety of the vehicle. The automobile buckle is one of the most important components in the automobile door lock system. During production and processing, the automobile buckle is formed by connecting two separate components, namely a lock ring and a lock plate, through a riveting process to become a new component, which can be used as an automobile door buckle. After riveting, the quality of the buckle needs to be detected.

[0003] For example, a pressing device for buckle riveting disclosed in a Chinese patent with the application number 2018113243391 includes a device main body. A limiting groove is provided on the surface of the device main body. Locking plates are provided at both ends of the limiting groove. Moving grooves are provided at both ends of the rear side of the device main body. Slide rods are provided inside the moving grooves. One end of each of the two locking plates is provided with a slider. A first spring is provided on one side of the slider. Guide plates are provided at both ends of the front side of the device main body. A connecting plate is provided between the two guide plates. By setting a pushing rod to extend between the two locking plates, the finished buckle is pushed towards the discharge port, which is convenient for taking out the finished buckle. However, errors will occur during the assembly before riveting of the buckle, which will affect the riveting quality.

[0004] Based on the above scheme, when aligning and assembling the U-shaped lock ring and the lock plate, since the surface of the U-shaped lock ring is smooth, it is easy for the U-shaped lock ring placed between the first placement seat and the second placement seat to be skewed, resulting in misalignment and unqualified assembly; due to burrs on the surface of the U-shaped lock ring or at the position of the lock holes on the lock plate, the pneumatic chuck is hindered during the downward movement, affecting the assembly efficiency and quality of the buckle; if there are impurities at the contact position between the U-shaped lock ring and the lock plate, it is easy for the lock plate to be in an inclined state, affecting the subsequent riveting quality.

[0040] As Figure 4 、 Figure 5 shown in the figure, the riveting press assembly 4 includes a riveting press table 401. Above the riveting press table 401, there is a hydraulic column 402. At the end of the hydraulic column 402 far from the riveting press table 401, there is a riveting plate 403.

At one end of the clamping block 4, there is a clamping cylinder 405. At one end of the riveting press table 401, there is a feeding track 406. At the end of the riveting press table 401 far from the feeding track 406, there is a discharging track

[0041] As Figure 7 、 Figure 8As shown in the figure, the quality inspection component 5 includes a first conveyor track 501. On one side of the first conveyor track 501, there is a pneumatic pressing frame 502. Above the first conveyor track 501, there is an inspection press head 503. On one side of the first conveyor track 501, there is a thickness detection mechanism 504. On the side of the first conveyor track 501 away from the thickness detection mechanism 504, there is a first screening hopper 505. At one end of the first conveyor track 501 away from the discharge track 407, there is a first flipping mechanism 506. At one end of the first flipping mechanism 506 away from the first conveyor track 501, there is a second conveyor track 507. At one end of the second conveyor track 507 away from the first flipping mechanism 506, there is a third conveyor track 510. Between the second conveyor track 507 and the third conveyor track 510, there is a vision detection mechanism 509. On one side of the second conveyor track 507, there is a second screening hopper 508.

[0042] As Figure 7 , Figure 9 shown in the figure, the marking and discharging component 6 includes a second flipping mechanism 601. The second flipping mechanism 601 is located on one side of the third conveyor track 510. On the side of the second flipping mechanism 601 away from the third conveyor track 510, there is a marking conveyor belt 602. On one side of the marking conveyor belt 602, there is an automatic marking machine 603. At one end of the marking conveyor belt 602 away from the second flipping mechanism 601, there is a discharge hopper 604. At one end of the discharge hopper 604 away from the marking conveyor belt 602, there is an adjustment hopper 605. On one side of the adjustment hopper 605, there is a link driving mechanism. Below the adjustment hopper 605, there is a storage box 606.

[0043] It should be noted that inside the automatic feeding chamber 101, there are vibrating trays 102 corresponding to the lock plate conveyor belt 103 and the U-shaped lock ring conveyor belt 104 respectively. Through the two vibrating trays 102, the lock plates and U-shaped lock rings are arranged in an orderly manner and provided with materials for the lock plate conveyor belt 103 and the U-shaped lock ring conveyor belt 104. The vibrating tray 102 is an auxiliary feeding device for an automatic assembly or automatic processing machine, which is prior art and will not be elaborated here.

[0044] During use, the locking plate conveyor belt 103 and the U-shaped locking ring conveyor belt 104 are respectively used to convey the locking plate and the U-shaped locking ring. During this process, the pneumatic clamping bracket 1031 and the pneumatic limiting bracket 1032 cooperate to position and clamp the locking plate on the locking plate conveyor belt 103, and the pneumatic clamping bracket 1031 is moved through the moving mechanism to transport the locking plate to the material taking position. The U-shaped locking ring on the U-shaped locking ring conveyor belt 104 is tightly clamped by the pneumatic locking block 1042. Then, the U-shaped locking ring conveyor belt 104 is transported between the first placement seat 207 and the second placement seat 208 through the moving feed frame 1041. Then, through the cooperation of the rotating mechanism 202, the rotating seat 203, and the lifting cylinder 204, the pneumatic chuck 205 clamps the locking plate at the material taking position and transports it above the U-shaped locking ring. At the same time, the controller controls the hydraulic push rod 210 to extend, and the hydraulic push rod 210 pushes the limiting push block 209 through the middle of the U-shaped locking ring and limits it. Then, under the action of the lifting cylinder 204, the pneumatic chuck 205 drives the locking plate to move downward, so that the U-shaped locking ring passes through the locking plate to complete the assembly. Then, the controller controls the driving cylinder 211 to extend and pushes the air claw 212 to be located above the locking plate. Then, the controller controls the pneumatic chuck 205 to release the locking plate, and under the action of the lifting cylinder 204, the pneumatic chuck 205 moves upward. At this time, under the action of the air claw 212, the displacement of the locking plate or the U-shaped locking ring is avoided, which affects the assembly accuracy. Then, the controller controls the driving cylinder 211 to contract, so that the air claw 212 returns to the initial state. At the same time, the controller controls the hydraulic push rod 210 to contract, and under the action of the hydraulic push rod 210, the limiting push block 209 returns to the initial state, avoiding affecting the subsequent operation of moving the assembled lock to the feeding track 406.

[0045] During the riveting process, the assembled lock is transported to the riveting position of the riveting table 401 through the feeding track 406. Then, the controller controls the clamping cylinder 405 to drive the clamping block 404 to fix the lock. Then, under the action of the hydraulic column 402, the riveting plate 403 performs riveting treatment on the lock, so that the locking plate and the locking ring are connected. After riveting, the riveting plate 403 is reset and the fixing of the clamping block 404 on the lock is released. The specific operation will not be described again, and the riveted lock is transported to the first conveyor track 501 through the discharging track 407 for inspection.

[0046] During detection, first, the buckle is limited by the pneumatic pressing frame 502. Then, the flatness of the buckle surface is detected by the detection pressure head 503. After the detection, the buckle moves to the lower part of the thickness detection mechanism 504, and the thickness detection mechanism 504 detects the thickness of the press riveting connection of the buckle. If the detection result of the buckle does not meet the processing standard, it is put into the first screening hopper 505. If the detection result of the buckle meets the processing standard, the buckle is flipped by the first flipping mechanism 506 to detect the other side of the buckle. It is transported to the lower part of the vision detection mechanism 509 for defect detection through the second conveyor track 507 and the mechanical gripper. If the detection result of the buckle does not meet the processing standard, it is put into the second screening hopper 508. If the detection result of the buckle meets the processing standard, it is transported to the second flipping mechanism 601 through the third conveyor track 510. Then, under the action of the second flipping mechanism 601, the buckle is flipped again. Then, it is transported to the lower part of the automatic marking machine 603 through the marking conveyor belt 602, and the surface of the buckle is marked by the automatic marking machine 603, which is a qualified product. The buckles marked on the marking conveyor belt 602 pass through the discharge hopper 604 and the adjustment hopper 605 in sequence and finally fall into the storage box 606.

[0047] It is found in the above process that when aligning and assembling the U-shaped lock ring and the lock plate, since the surface of the U-shaped lock ring is smooth, it is easy for the U-shaped lock ring placed between the first placement seat 207 and the second placement seat 208 to be skewed, resulting in misalignment and unqualified assembly; since there are burrs at the position of the surface of the U-shaped lock ring or the lock holes on the lock plate, the pneumatic chuck 205 is hindered during the downward movement, affecting the assembly efficiency and quality of the buckle; if there are impurities at the contact position between the U-shaped lock ring and the lock plate, it is easy for the lock plate to be in an inclined state, affecting the subsequent press riveting quality.

[0048] To solve the above problems, the device further includes:

[0049] As Figures 10 to 12 shown, the positioning and detection component 3 includes an electric telescopic rod 301. The output end of the electric telescopic rod 301 is provided with a first wedge block 302. One end of the first wedge block 302 away from the electric telescopic rod 301 is provided with a limiting cylinder 303. A compression spring 304 is arranged inside the limiting cylinder 303. One end of the compression spring 304 away from the limiting cylinder 303 is provided with a sliding rod 305. One end of the sliding rod 305 away from the compression spring 304 is provided with a clamping head 306. A pressure sensor is arranged inside the clamping head 306 to detect the magnitude of the pressure received by the clamping head 306 when moving downward.

[0050] Above the first wedge block 302, there is a second wedge block 307. Above the second wedge block 307, there is a positioning cylinder 308. Inside the positioning cylinder 308, there is a detection spring 309. One end of the detection spring 309 away from the positioning cylinder 308 is provided with a detection rod 310. One end of the detection rod 310 close to the detection spring 309 is provided with a displacement sensor for detecting the displacement of the detection rod 310 in the positioning cylinder 308.

[0051] On one side of the second wedge block 307, there is a positioning bracket 311. A chute is opened at the position where the second wedge block 307 is connected to the positioning bracket 311. The electric telescopic rod 301 is arranged below the positioning bracket 311 and is connected to the bottom end of the positioning bracket 311.

[0052] The surfaces of the first placement seat 207 and the second placement seat 208 are both provided with positioning holes adapted to the positioning cylinder 308.

[0053] When aligning and assembling the U-shaped lock ring and the lock plate, since the surface of the U-shaped lock ring is smooth, it is easy for the U-shaped lock ring placed between the first placement seat 207 and the second placement seat 208 to be skewed. At this time, the positioning and detection component 3 detects the offset degree of the lock ring and corrects it. Specifically, first, the controller controls the four electric telescopic rods 301 to extend a preset length. The electric telescopic rods 301 push the first wedge block 302, the limiting cylinder 303, the sliding rod 305, and the clamping head 306 to move together in the direction close to the U-shaped lock ring, so that the clamping head 306 contacts the surface of the U-shaped lock ring. During this process, the compression spring 304 is compressed. Then, the pressure sensor detects the pressure values received by the clamping head 306 at different positions of the U-shaped lock ring. If the pressure detection values of the two clamping heads 306 at the relative positions of the U-shaped lock ring detected by the pressure sensor are different at this time, it indicates that the pressures received by the two clamping heads 306 at the relative positions of the U-shaped lock ring are different, and the U-shaped lock ring is in a skewed state. At this time, by calculating and comparing the difference between the pressure values of the two clamping heads 306 at the relative positions of the U-shaped lock ring, the offset degree of the U-shaped lock ring can be obtained. Then, the controller controls the electric telescopic rod 301 at the position with a larger pressure detection value to extend. During this process, the electric telescopic rod 301 pushes the first wedge block 302, the limiting cylinder 303, the sliding rod 305, and the clamping head 306 to move together in the direction close to the U-shaped lock ring, so that the clamping head 306 applies a thrust to the U-shaped lock ring, thereby achieving the purpose of correcting the U-shaped lock ring. When the detection values of the pressure sensors on the four clamping heads 306 are equal, that is, the correction of the U-shaped lock ring is completed.

[0054] Meanwhile, when the first wedge block 302 moves towards the U-shaped locking ring, the first wedge block 302 squeezes the second wedge block 307, causing the second wedge block 307 to move upward in the vertical direction along the sliding groove on the positioning frame 311. That is, the second wedge block 307 drives the positioning cylinder 308, the detection spring 309, and the detection rod 310 to move upward together. At this time, the detection spring 309 is in its original length state, and the top end of the detection rod 310 does not extend out of the positioning hole.

[0055] Due to burrs existing on the surface of the U-shaped locking ring or at the position of the locking hole on the locking plate, the pneumatic chuck 205 is hindered during the downward movement. By setting a force sensor on the pneumatic chuck 205, when the pneumatic chuck 205 drives the locking plate to move downward together under the action of the lifting cylinder 204, during this process, the resistance when the locking plate passes through the U-shaped locking ring is detected by the force sensor. If the detected value of the force sensor is not zero, it indicates that there are burrs on the surface of the U-shaped locking ring or at the position of the locking hole on the locking plate. To ensure the normal progress of the lock assembly, the burrs need to be cleaned at this time. Specifically:

[0056] The controller controls the lifting cylinder 204 to drive the pneumatic chuck 205 and the locking plate to reciprocate, so that the U-shaped locking ring and the locking plate interact with each other, thereby scraping the burrs on the surface of the U-shaped locking ring by the locking hole on the locking plate or making the burrs at the locking hole on the locking plate fall off by the collision of the U-shaped locking ring, realizing the cleaning of the burrs on the surface of the U-shaped locking ring or at the position of the locking hole on the locking plate, so that the locking plate can pass through the U-shaped locking ring smoothly to achieve the assembly.

[0057] To avoid the displacement of the U-shaped locking ring when cleaning the burrs, before that, the controller controls the four electric telescopic rods 301 to extend respectively. The electric telescopic rods 301 push the first wedge block 302, the limiting cylinder 303, the sliding rod 305, and the clamping head 306 to move towards the U-shaped locking ring together. The compression spring 304 is compressed, so that the clamping force of the clamping head 306 on the U-shaped locking ring increases, so that the detected value of the pressure sensor on the clamping head 306 reaches the preset value. At this time, the clamping head 306 will not cause extrusion damage to the U-shaped locking ring itself. At the same time, the controller controls the hydraulic push rod 210 to extend, and the hydraulic push rod 210 pushes the limiting push block 209 to pass through the U-shaped locking ring to achieve positioning and locking.

[0058] During the above process, that is, when the first wedge block 302 moves towards the U-shaped locking ring, the first wedge block 302 squeezes the second wedge block 307, causing the second wedge block 307 to move upward in the vertical direction along the sliding groove on the positioning frame 311. That is, the second wedge block 307 drives the positioning cylinder 308, the detection spring 309, and the detection rod 310 to move upward together. At this time, the detection spring 309 is in its original length state, and the top end of the detection rod 310 extends out of the positioning hole, preparing for subsequent detection of whether the assembled locking plate is in an inclined state.

[0059] When the pneumatic chuck 205 places the lock plate on the U-shaped lock ring, at this time, both ends of the lock plate are in contact with the surfaces of the first placement seat 207 and the second placement seat 208 respectively. At this time, the detection rod 310 is subjected to the pressure of the lock plate, and the detection spring 309 is compressed, so that the detection rod 310 moves away from the lock plate in the positioning cylinder 308. That is, the displacement sensor detects the displacement of the detection rod 310 in the positioning cylinder 308. By comparing the displacements of the four detection rods 310 in the positioning cylinder 308, it can be determined whether the lock plate is in an inclined state. If the displacements of the four detection rods 310 in the positioning cylinder 308 are different, it indicates that there may be burr impurities at the contact position between the U-shaped lock ring and the lock plate, resulting in the lock plate being in an inclined state, which may cause problems such as unevenness, inclination, or deformation of the components after riveting, affecting the subsequent riveting quality. At this time, the controller controls the four electric telescopic rods 301 to reciprocate respectively. Specifically, when the electric telescopic rod 301 extends, the first wedge block 302 squeezes the second wedge block 307, so that the second wedge block 307 moves upward in the vertical direction along the chute on the positioning frame 311. That is, the second wedge block 307 drives the positioning cylinder 308, the detection spring 309, and the detection rod 310 to move upward together. And at this time, the air claw 212 is located above the lock plate to play a limiting role. During this process, the detection rod 310 retracts into the positioning cylinder 308, and the positioning cylinder 308 collides with the lock plate to generate vibration, so that the burr impurities adhering to the lock plate fall off. When the electric telescopic rod 301 contracts, the second wedge block 307 moves downward in the vertical direction along the chute on the positioning frame 311. That is, the second wedge block 307 drives the positioning cylinder 308, the detection spring 309, and the detection rod 310 to move downward together, so that the lock plate impacts the contact position of the lock ring to break the burr impurities, and at the same time, the impact generates vibration to make the burrs fall off.

[0060] By repeating the above operations, the burr impurities at the contact position between the U-shaped lock ring and the lock plate are cleaned. Then, the controller controls the electric telescopic rod 301 to return to the state during detection, so that the detection rod 310 detects the inclination degree of the lock plate again. If the displacements of the four detection rods 310 in the positioning cylinder 308 are the same, it indicates that the lock plate is in a parallel state.

[0061] It should be noted that if the displacements of the four detection rods 310 in the positioning cylinder 308 are different and the displacements are within the standard range, at this time, by increasing the riveting force of the riveting assembly 4, the lock plate is flattened, so that the lock plate on the lock buckle after riveting meets the riveting standard.
