Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of safety belt buckle assembly, in particular to a bow spring assembly guiding installation device and method. BACKGROUND

[0002] At present, with the continuous improvement of people's growing material living standards, the number of cars is increasing. For driving, you must wear a seat belt. The seat belt is a necessary safety guarantee for people driving a car and is an important part of the passive safety system of the car.

[0003] A general seat belt is composed of a lock piece and a seat belt buckle. The lock piece is clamped in the seat belt buckle to form a lock for the seat belt. The seat belt buckle includes a housing, a slot seat, a buckle piece, an unlocking button, a bolt shaft, a bow spring assembly spring, a button, and other parts. The unlocking button is connected to the housing through the bolt shaft. The unlocking button includes a bow spring assembly and a button. Pressing the button drives the bow spring assembly to slide, so that the bolt shaft drives the buckle piece to lock the lock piece. The spring provides appropriate spring force to complete the corresponding buckling and unlocking functions (CN202211188944.7).

[0004] Generally, assembling a seat belt buckle requires assembling the slot seat, bow spring assembly, buckle piece, spring, bolt shaft, button, and housing in the appropriate assembly process. The first step in the assembly process is to assemble the bow spring assembly with the slot seat. In this process, the bow spring assembly needs to be introduced into the installation slot hole of the slot seat through a complex composite motion. The spatial motion trajectory of the bow spring assembly during assembly can be decomposed into three degrees of freedom of translational motion and one degree of freedom of rotational motion. The overall assembly difficulty of this process is extremely high, and the assembly trajectory is complex.

[0005] According to the above installation process requirements of the bow spring assembly and the slot seat, there are currently two relatively mature assembly methods: one is to complete the pre-assembly of this process manually; the other is to use a six-axis robot to grab the bow spring assembly to achieve a complex assembly trajectory.

[0006] The above two methods have low assembly efficiency and long assembly time. In the entire buckle assembly process, it is a bottleneck process that will greatly increase the imbalance rate of the assembly line and reduce production efficiency. The deployment cost of the six-axis robot solution is high, and the installation and debugging of the bow spring assembly assembly trajectory is complex, which greatly increases the operating cost of the assembly line. SUMMARY

[0007] In view of the deficiencies of the prior art, the purpose of the present application is to provide a bow spring assembly guiding installation device to achieve efficient bow spring assembly installation at a relatively low cost, thereby reducing costs and increasing efficiency for factory production of seat belt buckles.

[0008] The application is implemented by at least one of the following technical solutions.

[0009] The guiding and mounting device of the bow and arrow assembly comprises a groove seat assembly, a groove seat tool, an assembly action execution mechanism, and a straight vibration feeding section.

[0010] The assembly action execution mechanism comprises a feeding track and a pressing and taking assembly. The bow and arrow assembly advances along the feeding track under the conveying of the straight vibration feeding section, is clamped by the pressing and taking assembly, and is finally transferred into the groove seat of the groove seat tool to complete the assembly process.

[0011] Further, the groove seat assembly comprises a groove seat and a bow and arrow assembly. The bow and arrow assembly comprises a pop-up piece and an arch piece. The pop-up piece and the arch piece are connected by a connecting pivot and are hinged. The pop-up piece and the arch piece can rotate relative to each other. The arch piece is located in the groove seat.

[0012] Further, the cross section of the groove seat is U-shaped. The middle part of the groove seat is a U-shaped channel. Assembly grooves are arranged on the opposite sides of the groove seat for embedding the two ends of the arch piece.

[0013] Further, the bottom of the groove seat tool is mounted on a ring track conveying line. The upper surface of the groove seat tool is arranged at a certain angle with the horizontal. After the groove seat is placed on the groove seat tool, the groove seat is at an angle with the horizontal. When the bow and arrow assembly is guided into the U-shaped channel, it also assumes an inclined posture, so that it can be guided and slid by gravity.

[0014] Further, the top of the feeding track is provided with a conveying track for conveying the bow and arrow assembly. A pushing feeding air cylinder is connected to the side of the feeding track. An assembly slide is arranged on one side of the pushing feeding air cylinder. The pushing feeding air cylinder is used to drive the assembly slide to move. The other side of the feeding track is provided with a left guiding arm and a right guiding arm for the bow and arrow assembly. The other ends of the left guiding arm and the right guiding arm extend into the assembly slide for guiding and positioning the bow and arrow assembly.

[0015] Further, a guiding slide corresponding to the size of the bow and arrow assembly is designed inside the assembly slide. An adjusting bolt is arranged on the upper part of the guiding slide for positioning the bow and arrow assembly. A pressing boss is arranged on one side of the upper part of the guiding slide.

[0016] Further, the pressing and taking assembly is located on the top of the assembly slide. The pressing and taking assembly comprises a pressing air cylinder mounting plate, a pressing air cylinder, and a pressing head. The pressing air cylinder mounting plate is located on the top of the assembly slide. The pressing air cylinder is mounted on the pressing air cylinder mounting plate. The pressing head is connected with the pressing air cylinder. The extension and retraction of the pressing head are controlled by the pressing air cylinder.

[0017] The upper surface of the pressing boss and the lower surface of the pressing head form a pressing clamping space, which is used to clamp and release the bow and arrow assembly.

[0018] Further, an L-shaped transition plate is connected between the assembly slide and the feeding track, one side of the L-shaped transition plate is connected to the top of the feeding track, the other side of the L-shaped transition plate extends into the assembly slide, and the upper surface of the L-shaped transition plate coincides with the track surface of the feeding track.

[0019] Further, the straight vibration feeding section includes a straight vibrator, and the feeding track of the assembly action execution mechanism is located on the mounting plate at the top of the straight vibrator.

[0020] The method for implementing the bow and arrow assembly guiding and mounting device includes the following steps:

[0021] The bow and arrow assembly advances along the feeding track under the conveying of the straight vibration feeding section, the bow piece is moved to the L-shaped transition plate from the feeding track, the ejector collides with the adjusting bolt to be limited, the lateral position of the bow and arrow assembly in the assembly slide is determined, the top end of the ejector is guided into the guiding slide between the pressing boss and the pressing head by the left guiding arm of the bow and arrow assembly and the right guiding arm of the bow and arrow assembly, the pressing head follows the pressing cylinder to extend, the lower surface of the pressing head moves towards the upper surface of the pressing boss, the upper end of the ejector between the lower surface of the pressing head and the upper surface of the pressing boss is pressed and fixed, so as to realize the fixed connection of the bow and arrow assembly and the assembly slide and realize the clamping of the bow and arrow assembly.

[0022] The advancing feeding cylinder extends to drive the assembly slide to move towards the groove seat and the groove seat tool, after moving to the limit position, the assembly slide is embedded in the U-shaped groove, and the contact surfaces of the assembly slide and the groove seat are arranged at the same angle with the horizontal, so that the U-shaped groove and the guiding slide are embedded in each other to form an internal cavity for constraining the sliding track of the bow and arrow assembly, and the bow and arrow assembly is guided and assembled in the internal cavity; the bow and arrow assembly is carried by the assembly slide, moves away from the upper surface of the L-shaped transition plate, and moves to the set release position above the U-shaped groove, and the bow and arrow assembly is in a suspended state and is connected to the guiding cavity formed by the U-shaped groove and the guiding slide.

[0023] After the assembly slide is embedded in the U-shaped groove, the guiding slide and the bow and arrow assembly reach the set initial position of the guiding and assembling, then the pressing cylinder retracts to drive the pressing head to move away from the pressing boss, the upper end of the ejector between the lower surface of the pressing head and the upper surface of the pressing boss loses the constraint, and the fixed connection with the assembly slide is released, so as to complete the release action of the bow and arrow assembly, then the bow and arrow assembly falls into the guiding slide in the internal cavity of the assembly slide under the action of gravity, the bow and arrow assembly is constrained by the inner wall of the guiding slide, after a short sliding, one end of the bow piece is embedded in the assembly groove on the two sides of the groove seat, and the first step of the guiding and assembling is completed.

[0024] After the projectile assembly is completed, the bottom of the bow-shaped part coincides with the bottom of the U-shaped channel. The attitude of the projectile assembly is at an angle to the horizontal. The top of the projectile rests on the inner wall of the guide slide. Under the combined constraints of the guide slide, the mounting slots on both sides, and the U-shaped channel, it is in a state of force balance, and the projectile assembly is stable and stationary as a whole.

[0025] After the projectile assembly is in a stable state, the feed cylinder retracts, causing the assembly slide to move away from the slotted seat and the slotted seat tooling direction. The assembly slide exits the U-shaped channel. At this time, the constraint of the guide slide on the projectile assembly disappears, causing the original force balance state to be broken. Under the constraint of both the assembly slots on both sides and the U-shaped channel, the projectile assembly continues to slide down under gravity, causing the protruding feature at the other end of the bow-shaped part to slide into the assembly slots on both sides, finally forming a new balance state and completing the assembly process of the projectile assembly and the slotted seat.

[0026] After the feeding cylinder returns to its initial position, the assembly slide also returns to its initial material picking position, thus completing one assembly cycle and preparing to enter the next cycle.

[0027] Compared with existing technologies, the present invention has the following advantages:

[0028] This invention utilizes a guided assembly method to achieve automated and efficient assembly of the projectile assembly and the slotted seat at low cost, solving the efficiency problem of manual assembly and avoiding the high cost of six-axis robotic arm solutions. It achieves the complex assembly process of the projectile assembly with the simplest mechanism, while also meeting the requirements for assembly success rate and efficiency.

[0029] Because the assembly mechanism is simple enough, the complex motion trajectory of the projectile assembly is constrained by the guiding method, which greatly reduces the number of moving parts that serve as the power source, reduces the risk of failure of moving parts, and greatly increases the operational stability of the device.

[0038] To enable those skilled in the art to better understand the present invention, the invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are merely some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0039] like Figure 1 , Figure 2 As shown, a projectile assembly guide installation device of this embodiment includes a slotted seat assembly 1, which includes a slotted seat 11 and a projectile assembly 12, which are assembled by a specific method and have a definite relative combination relationship in their assembly features.

[0040] The projectile assembly 12 includes a projectile 121 and an arch-shaped component 122, which are hinged together by a connecting shaft 123. The projectile 121 and the arch-shaped component 122 can rotate relative to each other at a certain angle.

[0041] In a preferred embodiment, the slotted seat 11 is a narrow and elongated part with a U-shaped cross-section. The middle part of the slotted seat 11 is a U-shaped channel 111, which is one of the assembly features and is a space available for assembling the projectile assembly 12. The bottom of the slotted seat 11 has assembly slots 112 on opposite sides for interlocking with the top features at both ends of the bow-shaped part 122.

[0042] like Figure 1 and Figure 2As shown, the basic assembly trajectory is as follows: the projectile assembly 12 is inserted into the U-shaped channel 111 of the slot seat with the narrower side of the bow-shaped part 122. The bottom of the bow-shaped part 122 coincides with the bottom of the U-shaped channel 111 of the slot seat. Then, the projectile assembly 12 is pushed to perform a composite motion of translation and rotation at the bottom of the U-shaped channel 111 of the slot seat, pushing the protruding feature at one end of the bow-shaped part 122 into the two side assembly slots 112 for mutual engagement. Then, the projectile assembly 12 is pushed to perform a composite motion, pushing the protruding feature at the other end of the bow-shaped part 122 into the two side assembly slots 112 for mutual engagement. Finally, the protruding features at both ends of the bow-shaped part 122 are pushed into the two side assembly slots 112 respectively and pushed to the bottom, completing the assembly process.

[0043] The above describes the basic assembly method of the projectile assembly 12 and the slotted seat 11, as well as the motion trajectory of the projectile assembly 12 during assembly. The specific structure of this embodiment will be described next.

[0044] like Figure 3 As shown, this is a schematic diagram of the overall structure. The overall layout of each component is a straight line. Taking the conveying direction of the projectile assembly 12 as a reference, all functional components are arranged on the same latitude to minimize the power source required for the conveying of the projectile assembly 12 and simplify the conveying track.

[0045] like Figure 3 As shown, the functional components from right to left are as follows: slotted seat fixture 2, used to place and position slotted seat 11 to facilitate subsequent assembly actions; assembly action execution mechanism 3, which is the main assembly action execution mechanism to realize the automated assembly process; and direct vibration feeding section 4, which includes a direct vibrator and a direct vibration track, used to receive the feed from the preceding vibratory plate and transport the projectile assembly 12 to the subsequent execution mechanism.

[0046] like Figure 3 As shown, the slotted seat fixture 2 is designed to fix the slotted seat 11 and undertake the function of station transfer. The bottom of the slotted seat fixture 2 is connected to the circular track conveyor line to realize the material transfer function of multiple stations and different processes. Furthermore, the upper surface of the slotted seat fixture 2 is arranged at a 45-degree angle to the horizontal, so that after the slotted seat 11 is placed on the fixture in the previous station, the whole is also at a 45-degree angle to the horizontal. When the projectile assembly 12 is introduced into the U-shaped channel 111 of the slotted seat, it also presents an inclined posture, so that it can be guided and slidably assembled by gravity.

[0047] like Figure 3As shown, the assembly action actuator 3 is located in the middle of the whole device. The assembly action actuator 3 includes a feeding track 31 and a pressing and picking component 36. The feeding track 31 serves as the main body for installation. The top of the feeding track 31 is the conveying track for the projectile assembly 12. A pushing feeding cylinder 32 is connected to the side of the feeding track 31. The movable end of the cylinder on the right side of the pushing feeding cylinder 32 is connected to the assembly slide 35. The top right end of the feeding track 31 is connected to the left guide arm 33 and the right guide arm 34 of the projectile assembly. The other ends of both extend into the assembly slide 35 for guiding and positioning the projectile assembly 12.

[0048] like Figure 4 As shown, the pressing and picking assembly 36 is installed at the top of the assembly slide 35. The pressing and picking assembly 36 consists of a pressing cylinder mounting plate 361, a pressing cylinder 362, and a pressing head 363. The lower end of the pressing cylinder mounting plate 361 is connected to the top of the assembly slide 35, the pressing cylinder 362 is connected to the upper part of the pressing cylinder mounting plate 361, and the pressing head 363 is connected to the lower end of the pressing cylinder 362, extending and retracting along with the lower end of the pressing cylinder 362.

[0049] like Figure 5 and Figure 7 As shown, the assembly slide 35 has a guide slide 353 of suitable width inside, which forms a through cavity. This cavity is specially designed to correspond to the outer dimensions of the projectile assembly 12, and can constrain the sliding posture and trajectory of the projectile assembly 12. On the upper left side of the guide slide 353, there is an adjusting bolt 351, which can be adjusted left and right to adjust the screw depth for positioning the projectile assembly 12. On one side of the upper part of the guide slide 353, there is a long strip-shaped boss feature pressing boss 352. The upper surface of the pressing boss 352 and the lower surface of the pressing head 363 form a pressing and clamping space. When the pressing head 363 follows the pressing... After the cylinder 362 extends, the lower surface of the pressing head 363 moves toward the upper surface of the pressing boss 352. The upper end of the ejector 121 located between the lower surface of the pressing head 363 and the upper surface of the pressing boss 352 is pressed and fixed, thereby realizing the fixed connection between the projectile assembly 12 and the assembly slide 35, which is the clamping state. When released, the pressing head 363 retracts with the pressing cylinder 362, and the lower surface of the pressing head 363 moves away from the upper surface of the pressing boss 352. The upper end of the ejector 121 located between the lower surface of the pressing head 363 and the upper surface of the pressing boss 352 is unconstrained, and the fixed connection with the assembly slide 35 is released, which is the release state.

[0050] The above describes the specific structure of the present invention. The following describes the working process and principle of the present invention.

[0051] As shown in the figure, after the previous station completes the loading of the slotted seat 11, the slotted seat fixture 2 carries the slotted seat 11 to the initial position shown in the figure, waiting for the projectile assembly 12 to be introduced and assembled.

[0052] like Figure 3 As shown, after the slotted seat fixture 2 reaches the designated position shown in the figure, the direct vibration feeding section 4 starts working, starts the direct vibrator, and pushes the projectile assembly 12 sequentially into the feeding track 31.

[0053] like Figure 4 As shown, the projectile assembly 12 is arranged sequentially in the loading track 31 and guided into the assembly slide 35 by the projectile assembly guide arms 33 and 34. The projectile assembly guide arms 33 and 34 are bolted to the top of the loading track 31, and can make a fine adjustment of the rotational degree of freedom with the connecting bolt as the pivot, so as to accurately guide the projectile assembly 12 into the designed pressing and clamping position.

[0054] like Figure 5 As shown, the right side of the L-shaped transition plate 37 is connected to the top left side of the loading track 31, and the left side of the L-shaped transition plate 37 extends into the assembly slide 35. The upper surface of the L-shaped transition plate 37 coincides with the track surface of the loading track 31, serving as a connecting transition between the assembly slide 35 and the loading track 31. After the projectile assembly 12 is successfully introduced into the assembly slide 35, the bow-shaped part 122 moves from the loading track 31 to the L-shaped transition plate 37, and the ejector part 121 collides with the adjusting bolt 351 to limit its movement, determining the lateral position of the projectile assembly 12 in the assembly slide 35. The top of the ejector part 121 is guided into the slide between the pressing boss 352 and the pressing head 363. The pressing cylinder 362 extends, driving the pressing head 363 to move towards the pressing boss 352, thereby completing the clamping action of the projectile assembly 12 and temporarily connecting the projectile assembly 12 and the assembly slide 35 into one unit.

[0055] like Figure 3 , Figure 5 and Figure 6 The feeding cylinder 32 extends, driving the assembly slide 35 to move towards the slotted seat 11 and the slotted seat tooling 2. After the movement is in place, the assembly slide 35 is embedded in the U-shaped channel 111 of the slotted seat. The contact surfaces of both are arranged at the same angle to the horizontal, so that the U-shaped channel 111 of the slotted seat and the guide slide 353 can fit together to form an internal cavity, which is used to constrain the sliding trajectory of the projectile assembly 12 and guide the assembly in sequence. The projectile assembly 12 is also carried by the assembly slide 35 to the release position set above the U-shaped channel 111 of the slotted seat.

[0056] like Figure 6 and Figure 7After the assembly slide 35 is inserted into the U-shaped channel 111 of the slotted seat, both the guide slide and the projectile assembly 12 reach the initial position of the guide assembly. Then, the pressing cylinder 362 retracts, driving the pressing head 363 away from the pressing boss 352, thereby completing the release action of the projectile assembly 12. Subsequently, under the action of gravity, the projectile assembly 12 falls into the guide slide 353 inside the assembly slide 35. The projectile assembly 12 is constrained by the inner wall of the guide slide. After a short slip, one end of the bow-shaped part 122 is successfully inserted into the assembly slots 112 on both sides of the slotted seat, completing the first step of the guide assembly.

[0057] like Figure 5 , Figure 6 and Figure 7 As shown, after the first step of assembling the projectile assembly 12 is completed, the bottom of the bow-shaped part 122 coincides with the bottom of the U-shaped channel 111 of the slotted seat, and the whole is at a 45-degree angle to the horizontal. The top of the projectile part 121 rests on the inner wall of the guide slide 353. Under the joint constraint of the guide slide 353, the mounting slots 112 on both sides and the U-shaped channel 111 of the slotted seat, it is in a state of force balance, and the projectile assembly 12 is stable and stationary.

[0058] like Figure 7 and Figure 3 As shown, after the projectile assembly 12 is in a stable state, the feed cylinder 32 retracts, causing the assembly slide 35 to move away from the slotted seat 11 and the slotted seat tooling 2. The assembly slide 35 exits the U-shaped channel 111 of the slotted seat. At this time, the constraint of the guide slide 353 on the projectile assembly 12 disappears, causing the original force balance state to be broken. Under the constraint of both the two side assembly slots 112 and the U-shaped channel 111 of the slotted seat, the projectile assembly 12 continues to slide down under gravity, causing the protruding feature at the other end of the bow-shaped part 122 to slide into the two side assembly slots 112. Figure 2 This process eventually creates a new equilibrium state, completing the assembly of the projectile assembly 12 and the slotted seat 11.

[0059] like Figure 3 As shown, after the feeding cylinder 32 returns to its initial position, the assembly slide 35 also returns to its initial material picking position, thus completing one assembly cycle and preparing to enter the next cycle.

[0060] The above embodiments are preferred embodiments of the present invention, but the embodiments of the present invention are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present invention shall be considered equivalent substitutions and shall be included within the protection scope of the present invention.
