Description

Technical Field

[0001] The present invention belongs to the technical field of seat belt buckle assembly methods, and particularly relates to an assembly and detection production line for buckle housings. Background Art

[0002] With the continuous improvement of people's living quality, the number of automobiles in possession increases year by year. As an important part of the vehicle passive safety system, the seat belt has a steadily increasing demand, and higher requirements are put forward for both production quality and quantity.

[0003] Generally, a seat belt consists of a retractor and a buckle. The webbing is pulled out from the retractor, and a section with a locking piece is inserted into the buckle to form the locking of the seat belt. The buckle includes structures such as a housing, a groove-shaped seat, and a bow spring assembly. The assembly of the housing is carried out after the assembly of the internal components of the buckle is completed.

[0004] Usually, the assembly of the buckle housing is mainly manual; the first step of the assembly is to place the assembled internal components into the lower housing of the buckle, and the relative position is ensured by the limits on the housing. Subsequently, the upper housing covers the lower housing part, and the fixation relies on internal buckles and subsequent ultrasonic welding. At this time, the buckle housing has been assembled. The second step is for workers to conduct appearance and function inspections, including checking whether there are scratches on the surface, whether the plugging and unplugging functions are normal, and whether the welding quality is reliable (CN201610868379.7). In addition, the replacement of the ultrasonic welding paper also needs to be completely manually completed. After the above steps are completed, it can be packed and sold.

[0005] The above processes are mainly completed manually, so there are problems such as difficulty in improving the production rhythm, difficulty in stabilizing the assembly quality, and difficulty in quantifying the detection indicators.

[0028] To implement the detection method of a lock housing assembly and detection production line as described above, the following steps are included:

[0029] Place the lock and the wire harness plug into the work carrier, manually move the work carrier to the double-speed chain line body, and the double-speed chain drives the work carrier to move forward.

Detailed implementation manners

[0052] To enable those skilled in the art to better understand the solution of the present invention, the following will further elaborate on the present invention in conjunction with the accompanying drawings and specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0053] As Figure 1 shown, an assembly and detection pipeline for a latch housing in this embodiment includes a welding rack 1, a workpiece carrier 2, a welding mechanism 3, a function detection mechanism 4, a laser engraving mechanism 5, a blocking and lifting mechanism 6, a double-speed chain conveyor 7, and a lifting and translation mechanism 8. All assemblies and mechanisms are arranged on the double-speed chain conveyor 7 installed on the welding rack 1, and the double-speed chain conveyor 7 serves as a transportation mechanism. The double-speed chain conveyor 7 is arranged on the welding rack.

[0054] The workpiece carrier 2 is arranged on the double-speed chain conveyor 7 and moves between various mechanisms.

[0055] The workpiece carrier 2 is arranged on the double-speed chain 712 of the double-speed chain conveyor 7, and the double-speed chain 712 is driven by a reduction motor 721 in the driving end module 72 to operate. The double-speed chain 712 drives the workpiece carrier 2 to move inside the linear profile 711. After reaching the corresponding working mechanism, the blocking and lifting mechanism 6 lifts the workpiece carrier 2 to the corresponding working position for the executing mechanism to perform corresponding operations. After the operation is completed, the blocking and lifting mechanism returns the workpiece carrier 2 to the double-speed chain 712 to continue moving along the conveyor. When it reaches the end of the conveyor, the lifting and translation mechanism 8 translates and transfers the workpiece carrier 2 to the double-speed chain 712 arranged in parallel in the next section.

[0056] The welding mechanism 3 is arranged on the double-speed chain conveyor and is separately on one side of the starting double-speed chain conveyor 7.

[0057] The function detection mechanism 4 is arranged on the welding rack and is located at the starting end of the double-speed chain conveyor 7.

[0058] The laser engraving mechanism 5 is arranged on the welding rack and is located at the end of the double-speed chain conveyor 7.

[0059] The blocking and lifting mechanism 6 is arranged on the double-speed chain conveyor 7 and is used for the work positions of each mechanism. The blocking and lifting mechanism 6 is installed on each of the mechanisms (3, 4, 5). When the workpiece carrier 2 moves to the work position of the corresponding mechanism, the blocking and lifting mechanism 6 lifts the workpiece carrier 2 to the work position of the corresponding mechanism, and then the executing mechanism performs corresponding actions.

[0060] The lifting and translation mechanism 8 is arranged on the double-speed chain conveyor 7 and is located at both the starting and ending ends of the double-speed chain conveyor 7.

[0061] As an embodiment, as Figure 2 shown in the schematic diagram of the tooling carrier structure, the tooling carrier 2 includes polyurethane rollers 21, latch clamps 22, tooling plates 23, positioning holes 24, movable bearing blocks 25, bolt clamps 26, relay amplifiers 27, and wire quick-disconnect interfaces 28; the latch clamps 22 are used to place latches. The polyurethane rollers 21 are in contact with the linear profile 711 to serve as the guide for the tooling carrier 2. The movable bearing blocks 25 are used to pad up the protruding part of the latch straight rod. The bolt clamps 26 are used to hold latch bolts. The relay amplifier 27 is electrically connected to the wire quick-disconnect interface 28 to facilitate the detection of the on-off detection mechanism 42 and to facilitate the insertion of the metal probe 422 into the wire quick-disconnect interface 28.

[0062] The polyurethane rollers 21, latch clamps 22, movable bearing blocks 25, bolt clamps 26, relay amplifiers 27, and wire quick-disconnect interfaces 28 are bolted to the tooling plate 23, and the tooling plate 23 is arranged on the double-speed chain 712 of the double-speed chain line body 7. When the tooling carrier 2 reaches the preset position, it is guaranteed that the tooling carrier 2 can accurately reach the preset position through the cooperation of the positioning hole 24 and the positioning pin.

[0063] As Figure 3 shown in the schematic diagram of the structure of the transportation line body, the double-speed chain line body 7 includes a line body main body 71, a driving end module 72, and a driven end module 73. The line body main body 71 includes a linear profile 711 and a double-speed chain 712. The linear profile 711 is installed on the welding rack 1, and the double-speed chain 712 is sleeved inside the linear profile 711. The driving end module 72 is bolted to one end of the linear profile 711 through a motor mounting plate 722, and the reduction motor 721 on the motor mounting plate 722 drives the double-speed chain 712 to move. The driven end module 73 is located at the other end of the linear profile 711, and the double-speed chain idler 731 of the driven end module 73 is installed at one end of the linear profile 711 through an idler mounting plate 732. When the line body needs to be tensioned and adjusted, adjust the position of the bolts connected to the linear profile 711, and thus the double-speed chain idler 731 connected to the idler mounting plate 732 can be adjusted synchronously.

[0064] As Figure 4 shown, the welding mechanism 3 includes an ultrasonic welding machine 31, a backlight 32, an industrial camera 33, a unwinding mechanism 34, and a winding mechanism 35; the unwinding mechanism 34 includes an unwinding mechanism mounting plate, a first stepping motor 341, a first coil top block 342, a first coil 343, and a first roller 344; the winding mechanism 35 includes a winding mechanism mounting plate, a second stepping motor 351, a second coil 352, a second roller 353, and a second coil top block 354;

[0065] The ultrasonic welding machine 31 is installed on the linear profile 711, and the unwinding mechanism mounting plate and the rewinding mechanism mounting plate are installed on the welding machine frame 1. The backlight 32 and the industrial camera 33 are installed on the welding machine frame 1 for visual inspection; the first coil material top block 342, the first coil material 343 and the first roller 344 are installed on the unwinding mechanism mounting plate for winding and unwinding operations. An optoelectronic sensor 345 is provided on the unwinding mechanism 34, and the stepping motor 341 and the stepping motor 351 are both connected to the optoelectronic sensor 345. The first stepping motor 341 is coaxially and tightly connected to the first coil material top block 342, and the first coil material 343 is connected to the first coil material top block 342 by interference fit. When the first stepping motor 341 rotates, it drives the first coil material top block 342 and the first coil material 343 to rotate simultaneously, and drives the first roller 344 to float up and down and rotate.

[0066] The second stepping motor 351, the second coil material 352, the second roller 353 and the second coil material top block 354 are installed on the rewinding mechanism mounting plate for rewinding operations. The second stepping motor 351 is coaxially and tightly connected to the second coil material 352, and the second coil material 352 is connected to the second coil material top block 354 by interference fit generated by pressing tightly. When the second stepping motor 351 rotates, it drives the second coil material top block 354 and the second coil material 352 to rotate simultaneously, and drives the second roller 353 to rotate.

[0067] After the workpiece carrier 2 moves to the predetermined position, the ultrasonic welding machine 31 presses down to assemble the buckle housing. During the downward movement of the ultrasonic welding machine 31, since the pressing part of the ultrasonic welding machine 31 is aligned with the first coil material 343 and the second coil material 352 in the linear direction, the coiled material part that is pulled out between the first coil material 343 and the second coil material 352 and is suspended in the middle has its position lowered under the drive of the ultrasonic welding machine 31. However, due to the invariance of the length of the pulled-out coiled material and the floating state of the first roller 344, the extended coiled material near the first coil material 343 will drive the first roller 344 to move upward. At this time, the first roller 344 leaves the detection range of the optoelectronic sensor 345, and the optoelectronic sensor completes one count. When the number of counts reaches the preset value, the stepping motor 341 of the unwinding mechanism 34 and the stepping motor 351 of the rewinding mechanism 35 will rotate respectively to perform the winding and unwinding operations on the coiled material, so as to complete the replacement of the middle part of the coiled material.

[0068] As Figure 5 shown, it is a schematic structural diagram of the function detection station. The function detection mechanism 4 includes a plug-in detection mechanism 41, a continuity detection mechanism 42, a visual detection mechanism 43 and a detection table 44; the plug-in detection mechanism 41 and the continuity detection mechanism 42 are installed on the welding machine frame 7, and the visual detection mechanism 43 and the continuity detection mechanism 42 are respectively located on the upper and lower surfaces of the detection table 44.

[0069] The plug-in detection mechanism 41 includes a mounting profile 411, a pen-shaped cylinder 412, a floating joint 413, a pen-shaped cylinder 414, a floating joint 415, a quick clamp 416, a locking piece 417, and an unlocking lever 418.

[0070] The mounting profile 411 is mounted on the welding frame 1, and the pen-shaped cylinder 412 is mounted on the mounting profile 411; the floating joint 413 is mounted on the pen-shaped cylinder 412, the pen-shaped cylinder 414 is mounted on the floating joint 415, the quick clamp 416 is mounted on the floating joint 413, the floating joint 415 is mounted on the quick clamp 416, the locking piece 417 clamped by the quick clamp 416, and the unlocking lever 418 is mounted on the floating joint 415.

[0071] As an embodiment, the on-off detection mechanism 42 includes a double-acting cylinder 421, a metal probe 422, and an on-off detection mechanism baffle 423. The double-acting cylinder 421 is located on the lower surface of the detection table 44, and the metal probe 422 is connected to the double-acting cylinder 421. The on-off detection mechanism baffle 423 is bolted to the lower surface of the detection table 44 and is located on both sides of the double-acting cylinder 421 to prevent the locking wire from being hooked on the double-acting cylinder 421.

[0072] The vision detection mechanism 43 includes a camera mounting bracket 431, an annular light source 432, and an industrial camera 433; the annular light source 432 is located on the upper surface of the detection table 44, and the industrial camera 433 is mounted on the upper surface of the detection table 44 through the camera mounting bracket 431, and the industrial camera 433 is located above the annular light source 432.

[0073] Among them, the plugging and unplugging function detection mechanism 41 and the vision function detection mechanism 43 operate synchronously. When the workpiece carrier 2 reaches the specified position, the pen-shaped cylinder 414 extends at this time. The pen-shaped cylinder 414 is connected to the floating joint 415, and the floating joint 415 drives the lock piece 417 clamped by the quick clamp 416 to move forward to lock the lock catch. When the pen-shaped cylinder 414 runs out of air, the pen-shaped cylinder 412 moves forward and relies on the unlocking lever 418 to unlock. Subsequently, the ring light source 432 and the industrial camera 433 are used for shooting to detect the plugging and unplugging quality. The on-off detection mechanism 42 has the double-axis cylinder 421 drive the metal probe 422 to reciprocate for on-off function detection. The on-off detection mechanism baffle 423 is to prevent the lock catch wire from hooking the double-axis cylinder 421. In the plugging and unplugging function detection link, the plugging and unplugging function detection mechanism 41 and the vision function detection mechanism 43 operate synchronously. When the workpiece carrier 2 is transported to the working position by the blocking and lifting mechanism 6, the pen-shaped cylinder 414 extends, and the floating joint 415 connected thereto drives the lock piece 417 clamped by the quick clamp 416 to move forward, thereby locking the lock catch. After the pen-shaped cylinder 414 runs out of air, the pen-shaped cylinder 412 advances forward and uses the unlocking lever 418 to perform the unlocking operation. Immediately afterwards, the vision function detection mechanism 43 starts to work, uses the ring light source 432 to provide illumination, and the industrial camera 433 takes pictures to detect the plugging and unplugging quality. At the same time, the on-off detection mechanism 42 is activated, and the double-axis cylinder 421 drives the metal probe 422 to reciprocate to carry out the on-off function detection. The on-off detection mechanism baffle 423 plays a role in this process to prevent the lock catch wire from hooking the double-axis cylinder 421 and ensure the smooth progress of the detection work.

[0074] As Figure 6 shown, the laser engraving mechanism 5 includes a laser engraving mounting plate 52 and a laser engraving machine 51. The laser engraving machine 51 is connected to the laser engraving mounting plate 52 by bolts. The laser engraving mounting plate 52 is located on the heightening block 53 and is connected to the welding rack 1 and the double-speed chain body 7 through the heightening block 53.

[0075] As Figure 7As shown in the figure, the blocking and lifting mechanism 6 includes a microswitch 61, a microswitch mounting plate 62, a check valve mounting plate 63, a check valve 64, a lifting module 65, and a blocking cylinder 659. The microswitch 61 and the check valve 64 are respectively mounted on the linear profile 711 through the microswitch mounting plate 62 and the check valve mounting plate 63. The lifting module 65 includes a lifting plate 651, a positioning pin 652, a threaded guide rod 653, a collar 654, a linear bearing 655, a lifting cylinder 656, and a lifting mechanism mounting plate 657. The positioning pin 652 is located on the upper surface of the lifting plate 651 and is tightly connected to the lifting plate 651. One side of the lifting cylinder 656 is mounted on the lifting mechanism mounting plate 657 by bolts. On both sides of the lower surface of the lifting mechanism mounting plate 657, there are lifting mechanism mounting pads 658. The lifting mechanism mounting pads 658 are located on the linear profile 711. The threaded guide rod 653 is fixed to the lower surface of the lifting mechanism mounting plate 657 through the collar 654 and the linear bearing 655. The threaded guide rod 653 is located on the side away from the blocking cylinder 659. The lifting cylinder 656 is fixed to the lower surface of the connecting lifting mechanism mounting plate 657 by bolts, close to the threaded guide rod 653. The lifting plate 651 is located on the upper surface of the lifting mechanism mounting plate 657 and is connected to the lifting cylinder 656. The blocking cylinder 659 is used to block the flowing work carrier 2. The blocking cylinder 659 is located on one side of the lifting module 65 close to the positioning pin 652. The blocking cylinder 659 is connected to the blocking cylinder mounting plate 6510 by bolts. The blocking cylinder mounting plate 6510 is connected to the linear profile 711 by bolts. The microswitch 61 is connected to the blocking cylinder 659.

[0076] After the work carrier 2 moves to the corresponding position, it first presses the microswitch 61 to transmit the in-place signal to the blocking cylinder 659, driving the work carrier 2 to be blocked. After being blocked, due to the action of the check valve 64, the work carrier cannot move backward. Subsequently, the lifting cylinder 656 drives the lifting plate 651 to move upward. Through the positioning function of the positioning pin 652, the work carrier 2 is positioned to the predetermined position and limited by the collar 654. When the work carrier 2 is about to reach the position of the execution mechanism, the work carrier 2 presses the microswitch 61 and the check valve 64 in sequence. At this time, the microswitch 61 will transmit the in-place signal of the work carrier 2 to the blocking cylinder 659. Because the check valve 64 has the property of one-way passage, the work carrier 2 blocked by the blocking cylinder 659 will be restricted by the check valve 64 and cannot move backward. Subsequently, the lifting cylinder 656 starts to work, driving the lifting plate 651 to move upward. During this process, the positioning pin 652 plays a positioning role to horizontally position the positioning hole 24 of the work carrier 2. At the same time, the threaded guide rod 653 mounted on the lifting plate 651 cooperates with the collar 654 to limit the work carrier 2 in the horizontal direction, ensuring that it accurately reaches the specified working position.

[0077] As shown Figure 8 in the figure, the lifting and translation mechanism 8 includes a lifting and translation mounting plate 81, a lifting and translation lifting plate 82, a stepping motor 83, a synchronous belt driving wheel 84, a synchronous belt driven wheel 85, a driving rod 86, a synchronous belt wheel set 87, a thin cylinder 88, a guide rod 89, a blocking plate 810, and a collar 811. The lifting and translation mounting plate 81 is fixed on the double-speed chain line body 7. The thin cylinder 88 and the guide rod 89 are both fixed on the lower surface of the lifting and translation mounting plate 81, and the guide rod 89 is near the thin cylinder 88. A collar 811 is arranged on the guide rod 89. The lifting and translation lifting plate 82 is located on the upper surface of the lifting and translation mounting plate 81, and the thin cylinder 88 is threadedly connected to the lifting and translation lifting plate 82. The blocking plate 810 is fixed to the upper surface of the lifting and translation mounting plate 81 by bolts and is located on one side of the lifting and translation lifting plate 82. The stepping motor 83, the synchronous belt driving wheel 84, the synchronous belt driven wheel 85, the driving rod 86, and the synchronous belt wheel set 87 are installed on the lifting and translation lifting plate 82. The driving rod 86 is connected to the synchronous belt driven wheel 85, the stepping motor 83 is connected to the synchronous belt driving wheel 84, and the synchronous belt driving wheel 84 and the synchronous belt driven wheel 85 are connected by the synchronous belt wheel set 87.

[0078] The lifting and translation mechanism 8 is used to translate the workpiece carrier 2 that has reached the end to another line body. When the workpiece carrier 2 reaches the predetermined position, it is blocked by the blocking plate 810, so that the workpiece carrier 2 no longer moves forward. At this time, the thin cylinder 88 installed on the lifting and translation mounting plate 81 extends, driving the lifting and translation plate 82 to move upward under the guiding action of the guide rod 89, and the axial limit is carried out by the collar 811. The stepping motor 83 drives the synchronous belt driving wheel 84 and the synchronous belt driven wheel 85 to rotate, and drives the driving rod 86 to rotate, and horizontally transports the workpiece carrier 2 through the synchronous belt wheel set 87.

[0079] To implement the detection method of the lock housing assembly and detection production line described above, the following steps are included:

[0080] Put the lock and the wire harness plug into the workpiece carrier 2, and manually move the workpiece carrier 2 to the double-speed chain line body 7. The double-speed chain 712 drives the workpiece carrier 2 to move forward. When it reaches the welding mechanism 3, it is blocked and stopped by the blocking and lifting mechanism of the welding mechanism 3, and the workpiece carrier 2 is preliminarily limited by the check valve and the blocking cylinder. Subsequently, the lifting module at the bottom of the line body rises, and the positioning pins on the lifting plate cooperate with the positioning holes of the workpiece carrier 2 to form precise positioning, and the workpiece carrier 2 is lifted to the working position. At the welding mechanism 3, the unwinding mechanism and the rewinding mechanism are used to adjust the winding and unwinding of the coil material to complete the assembly of the lock housing. The lifting module lowers the workpiece carrier 2 to the double-speed chain, the blocking cylinder retracts, and the workpiece carrier 2 continues to move forward;

[0081] The industrial loading tool 2 moves to the lifting and translation mechanism 8, and the industrial loading tool 2 is stopped by the blocking plate 810. The lifting and translation mechanism 8 rises, moves the industrial loading tool 2 to the translation station, the synchronous pulley set moves forward, transports the industrial loading tool 2 to the parallel line body, and the industrial loading tool 2 continues to move forward driven by the double-speed chain. The blocking and lifting mechanism of the function detection mechanism 4 stops it, and at the same time, the plugging function detection and the on-off function detection are carried out. Among them, for the plugging function detection, first, the pen-shaped cylinder pushes the locking piece forward, the locking piece is locked by the lock catch, the pen-shaped cylinder cuts off the air supply, and then the pen-shaped cylinder drives the unlocking rod to unlock.

[0082] Subsequently, the industrial loading tool moves to the laser engraving mechanism 5, and the blocking and lifting mechanism of the laser engraving mechanism 5 stops it. After the industrial loading tool 2 reaches the working position, laser engraving is carried out using a laser engraving machine. After engraving, the industrial loading tool 2 moves to the lifting and translation mechanism 8. At this time, the industrial loading tool 2 returns to the original position, and the worker unloads the material. At this time, a cycle task is completed, and the line body enters the next cycle action.
