Description

Technical Field

[0001] This application relates to the technical field of pedal simulator housings, and in particular to a disc spring feeding platform. Background Technology

[0002] The pedal simulator housing is the core load-bearing and sealing substrate of the pedal simulator in an automotive brake-by-wire system (electro-hydraulic brake EHB). Inside the housing are multiple disc springs (also known as Belleville springs), which are one of the core elastic elements simulating the feel of a real brake pedal.

[0003] The bottom of the housing needs to be marked. Since the orientation of multiple disc springs varies, the housing usually needs to be marked and then the multiple disc springs are installed into the housing after multiple different clamping processes. This results in a long time for marking and disc spring assembly. Moreover, multiple clamping processes can easily lead to incorrect disc spring installation orientation, reducing assembly efficiency and quality. Summary of the Invention

[0004] To improve assembly efficiency and quality, this application provides a disc spring feeding platform.

[0005] This application provides a disc spring feeding table, which adopts the following technical solution: A disc spring feeding platform includes a machine body and a feeding device disposed on the machine body, the feeding device comprising: The feeding tray is rotatably mounted on the machine body, and multiple feeding holes for positioning the housing are arranged in a circular array around the axis of the feeding tray. The feeding mechanism is used to place the housing onto the feeding hole to achieve feeding, with the opening of the housing facing downwards; The marking mechanism is used to mark the bottom of the casing; The flipping mechanism flips the housing and places it on the loading hole for positioning, ensuring that the opening of the housing faces upwards. Multiple mounting mechanisms are used to sequentially install multiple disc springs into the housing as required; The unloading mechanism is used to grab and unload the housing with the disc springs installed; the rotation of the loading plate causes the housing to be loaded, marked, flipped, installed with multiple disc springs, and unloaded in sequence.

[0006] By adopting the above technical solution, the feeding tray rotates intermittently. The feeding mechanism starts and puts the shell into the feeding hole with the opening facing down. It flows with the feeding tray to the marking station to complete the bottom marking. It continues to flow to the flipping station, where the flipping mechanism starts to take out the shell, flip it 180° and put it back into the same feeding hole, changing it to the opening facing up. Then it passes through multiple installation mechanisms in sequence. Each installation mechanism is equipped with one disc spring. The disc springs are stacked one by one to a specified number. Each disc spring is assembled in a specified direction. Finally, it flows to the unloading station to complete the finished product grabbing and unloading.

[0007] The five independent processes of shell loading, bottom marking, posture flipping, stacking of multiple disc springs, and finished product unloading are integrated into a single rotating machine, eliminating the need for manual transfer and repeated loading and unloading between multiple machines. The entire production process can be completed by a single machine. The same loading hole can carry shells with both openings facing down and openings facing up. Marking and assembly share the same set of positioning carriers, eliminating the need to design two sets of independent positioning fixtures, thus reducing tooling manufacturing costs and changeover and debugging time.

[0008] Multiple installation mechanisms are independently arranged along the circumference, with each station completing only the assembly of a single disc spring. The action logic is simple, and the repeatability is high, avoiding the cumulative errors caused by reciprocating pressing at a single station. The concentricity and perpendicularity consistency of multi-piece stacking are significantly improved. At the same time, the "reverse installation for bottom marking + forward installation for disc spring" posture flow process directly adapts to the industry-standard requirement of marking the bottom of the disc spring assembly housing, filling the technical gap of rotary disc spring assembly equipment without a marking process. The intermittent indexing operation mode of the rotary table provides stable cycle time, and each station operates in parallel. The capacity requirements can be flexibly adapted by adjusting the rotary table speed and the number of stations, making it easy to connect to a fully automated production line, thereby greatly improving assembly efficiency and quality.

[0009] Optionally, the mounting mechanism includes: The push plate is radially slidably mounted on the machine body along the feeding tray, and a placement groove is provided on the upper surface near the feeding tray. The placement groove passes through the push plate near the feeding tray and has a vertically penetrating insertion hole. The feeding assembly is used to stack multiple disc springs as required and to limit the disc springs so that the lowest disc spring is placed on the placement slot. The push rod is vertically slidably mounted on the machine body and is positioned corresponding to the feeding hole; An elastic pusher assembly is located on the pusher rod and is elastic; Detection component, used to detect the position of the elastic pusher assembly; The pusher plate pushes the disc spring at the lowest point to move directly below the push rod. The push rod moves down, passes through the disc spring, and extends into the housing. At the same time, it pushes the elastic pusher assembly down to press against the disc spring for positioning. The detection component detects the elastic pusher assembly and determines that a disc spring is present. The pusher plate moves back and causes the disc spring to disengage from the placement slot under the restriction of the push rod. The disc spring is installed into the housing under the action of elastic force and the guidance of the push rod. After the elastic pusher assembly moves up, the feeding tray rotates. If no disc spring is placed in the placement slot, the elastic pushing component moves down through the insertion hole under the action of elastic force. If the detection component does not detect the elastic pushing component, the disc spring is fed repeatedly until the detection component detects the disc spring. After the disc spring is installed, the feeding tray rotates again.

[0010] By adopting the above technical solution, the single disc spring at the bottom of the feeding assembly falls into the placement slot of the push plate, and the push plate pushes the disc spring radially to directly below the push rod; the push rod moves down, passes through the inner hole of the disc spring, and extends into the housing, while the elastic push assembly moves down and presses against the disc spring. The detection component recognizes the signal of the elastic push assembly and determines that there is material; the push plate retracts, and the disc spring is radially limited and blocked by the push rod, automatically disengaging from the placement slot. Under the pressure of the elastic push assembly and the guiding action of the push rod, it falls smoothly into the housing; if there is no disc spring in the placement slot, the elastic push assembly is not blocked when the push rod moves down, and continues to move down through the insertion hole of the push plate. The detection component does not recognize the signal and determines that there is a shortage of material. The equipment automatically repeats the pushing action until the disc spring is detected before the feeding tray is allowed to rotate.

[0011] By using a push rod to penetrate the inner hole of the disc spring to form a radial limit, the disc spring is rigidly blocked and automatically disengages from the placement slot when the push plate retracts. This eliminates the need for auxiliary unloading structures such as suction cups and air blowing, completely avoiding the industry pain points of "material carrying back and skewed dropping" in traditional push plate feeding. The disc spring's dropping posture is stable, greatly improving the assembly qualification rate. At the same time, the placement slot and the insertion hole through the push plate allow the disc spring to move forward, and the push plate will not obstruct the disc spring when retracting, reducing the risk of damage to the disc spring and improving assembly efficiency and quality.

[0012] The presence or absence of disc springs is identified by the positional changes of the elastic pusher component. This is a penetrating physical detection method, unaffected by dust, light, or oil, and its detection reliability is far superior to traditional surface-mount photoelectric sensors. Combined with automatic retry logic, it completely eliminates the problem of missing disc springs. The pusher rod simultaneously performs three functions: "guiding material removal, pressing and limiting, and detection triggering." The elastic pusher component simultaneously achieves "elastic holding and position detection triggering." Detection and pressing reuse the same actuator, eliminating the need for an additional independent detection station, resulting in a compact structure and lower cost.

[0013] The control logic of automatically retrying when materials are out of stock and only allowing the feeding tray to rotate after passing the inspection avoids empty workstations due to single feeding failures, reduces the frequency of downtime and manual intervention, ensures the coaxiality of the disc spring and the housing by the push rod guide, and prevents the disc spring from falling and bouncing due to impact. The stacking accuracy is much higher than that of robotic arm gripping assembly, further improving assembly efficiency and quality.

[0014] Optionally, the push rod is provided with a push groove, and the elastic push assembly includes: The pusher block is slidably mounted on the pusher groove and extends outside the pusher groove; An elastic element is connected to the upper surface of the pusher groove and the pusher block, and is used to drive the pusher block to move down and press against the pusher groove for positioning; if the placement groove has a disc spring, the pusher block moves down and presses against the disc spring for positioning, and the detection element detects the presence of the pusher block; if the placement groove does not have a disc spring, the pusher block moves down through the insertion hole, and the detection element does not detect the pusher block.

[0015] By adopting the above technical solution, under normal conditions, the pusher block extends out of the pusher rod surface under the action of the elastic element; when there is a disc spring below, the pusher rod moves downward, the lower end face of the pusher block abuts against the upper end face of the disc spring, and the pusher block compresses the elastic element upward relative to the pusher groove, maintaining the extended state and being identified by the detection element; when there is no disc spring below, the pusher block is not obstructed, moves down synchronously with the pusher rod and passes through the insertion hole of the pusher plate, and the position is lower than the detection range of the detection element, triggering the material shortage judgment.

[0016] The system utilizes a purely mechanical linkage trigger, with the detection position rigidly guaranteed by the limiting structure of the pusher groove. This eliminates the drift and interference issues associated with electronic components, ensuring consistent detection accuracy even in dusty and oily production environments. The elastic element provides flexible holding force, guaranteeing smooth descent of the disc spring while preventing damage to the disc spring surface and housing from rigid pressing impacts, thus reducing workpiece scrap rates. Composed of only two core components—the pusher block and the elastic element—embedded within the pusher rod, there are no exposed pipelines, facilitating easy disassembly and replacement and resulting in extremely low maintenance costs. The elastic element automatically compensates for contact wear between the pusher block and the disc spring, eliminating the need for long-term detection position adjustments and significantly improving assembly efficiency and quality.

[0017] Optionally, a limiting surface is formed on the body, and when the disc spring located on the placement slot moves below the limiting surface, the limiting surface prevents the disc spring from disengaging from the placement slot.

[0018] By adopting the above technical solution, when the push plate pushes the disc spring to the assembly position, the limiting surface always covers the disc spring, restricting the vertical jump of the disc spring; when the push plate retracts, the limiting surface blocks the disc spring from above, and together with the radial limiting of the push rod, a "vertical + radial" all-round limiting is formed, which completely prevents the disc spring from following the push plate back due to friction or jumping away from the assembly position due to bouncing, thus improving assembly efficiency and quality.

[0019] Optionally, the feeding assembly includes: The feeding cylinder is set on the machine body, and multiple disc springs are stacked vertically inside the feeding cylinder. The outer wall of the disc springs abuts against the inner wall of the feeding cylinder for guidance and limiting. The cover plate is rotatably mounted on the machine body and abuts against the top of the feeding cylinder, and is used to seal the top of the feeding cylinder; when a disc spring needs to be inserted, the cover plate rotates to open the top of the feeding cylinder.

[0020] By adopting the above technical solution, the disc springs are neatly stacked vertically in the feeding cylinder, and the cylinder wall forms a circumferential guide for the disc springs to prevent the stack from tilting. When replenishing materials, the cover is opened and the whole stack of disc springs is put into the cylinder. After the cover is closed, the cylinder opening is sealed, which plays a role in preventing dust and debris from falling in, and at the same time restricting the disc springs from popping out.

[0021] The cylinder wall provides full-circumference guidance, ensuring high concentricity of the stacked disc springs and preventing tilting or jamming. This guarantees that the bottom disc spring falls smoothly into the pusher plate placement slot, reducing material jamming issues. A cover plate seals the cylinder opening, effectively preventing dust, oil, and debris from falling into the cylinder and contaminating the disc springs and housing, thus improving product cleanliness. The flip-type cover plate opens and closes easily, supporting one-time replenishment of the entire stack of disc springs without the need for individual placement, resulting in high replenishment efficiency and short downtime for replenishment, further improving assembly efficiency and quality.

[0022] Optionally, the cover plate is provided with a clearance groove and further includes a counterweight mechanism, the counterweight mechanism comprising: The counterweight ring is vertically slidably installed inside the feed cylinder and presses against the disc spring at the highest point under the action of gravity; The guide rod is vertically slidably mounted on the counterweight ring, and has a locking groove one at one end and a locking groove two at the other end; An elastic sheet is set on the counterweight ring, and is elastic, and is snapped into the snap-fit ​​groove one or snap-fit ​​groove two for positioning; The alarm component provides an alert when the number of disc reeds falls below a specified threshold. Place the guide rod vertically upwards near the first snap-fit ​​groove, push the guide rod upwards and make the elastic sheet press against the second snap-fit ​​groove for positioning; slide multiple disc springs onto the guide rod and press against the upper surface of the counterweight ring for positioning, place the guide rod downwards and place multiple disc springs into the feeding cylinder, rotate the cover plate against the top of the feeding cylinder and make the guide rod position on the relief groove, pull the guide rod upwards to above all the disc springs, and make the elastic sheet insert and install on the first snap-fit ​​groove for positioning under the action of elastic force, and the counterweight ring presses against the disc spring at the highest position for positioning under its own weight and the weight of the guide rod. As the number of disc springs decreases, the guide rod moves downwards.

[0023] By adopting the above technical solution, the counterweight ring is inverted, the elastic plate is disengaged from the first locking groove, the guide rod is pulled upward, the elastic plate is locked into the second locking groove below for positioning, and the guide rod extends upward. Multiple disc springs are then stacked on the counterweight ring along the guide rod to form a complete stack of materials. The cover plate is rotated to open the feeding cylinder, and the complete stack of materials is inverted and placed into the feeding cylinder. The cover plate rotates back, allowing the guide rod to pass through the clearance groove, thereby facilitating the placement of the complete stack of disc springs into the feeding cylinder and improving feeding efficiency.

[0024] The elastic plate is disengaged from the first and second locking slots. The guide rod is pulled upwards, and the elastic plate switches to the upper locking slot one for positioning. The guide rod is then retracted to the top of the disc spring. Under its own weight, the counterweight ring continuously presses on the uppermost disc spring and moves downwards synchronously as the disc spring is consumed, always maintaining downward pressure on the disc spring stack. This reduces the risk of the disc spring not being successfully placed in the placement slot and reduces the risk of wasting time due to repeated loading, further improving assembly efficiency and quality.

[0025] Meanwhile, as the number of disc springs decreases, when the number falls below a specified value, the alarm component will sound an alarm. The staff will then pull the guide rod upwards, and the cover will rotate and open. The guide rod and counterweight ring will be removed, and the above process will be repeated. This further ensures the success rate of disc spring installation, reduces the risk of wasting time due to repeated loading, and further improves assembly efficiency and quality.

[0026] The counterweight ring continuously presses down on the disc springs under the action of gravity, eliminating the gaps and jams caused by friction and burrs between the disc springs, ensuring that the bottom disc spring always falls reliably into the push plate placement slot, greatly improving the feeding success rate and further improving assembly efficiency and quality.

[0027] The guide rod serves as the loading guide, allowing the entire stack of disc springs to be pre-installed and placed into the material cylinder at once, resulting in rapid material replenishment. The dual-position structure enables quick switching between loading and operating modes, simplifying operation without tools. The self-weight-based pressing force remains constant and does not change with material height, avoiding the problems of excessive pressure when the material is full or insufficient pressure when the material is low compared to spring-loaded feeding, thus ensuring better feeding consistency. The counterweight and guide are integrated into one unit, eliminating the need for an external pressing structure. The overall size of the material cylinder is compact, fitting well in tight installation spaces around the turntable.

[0028] Optionally, the alarm component includes: The positioning ring is located on one end of the guide rod near the second locking groove, and it facilitates pulling the guide rod upward. A sensor is installed on the cover plate; the guide rod moves down to drive the positioning ring to move down, and an alarm is triggered when the positioning ring abuts against the sensor, ensuring that at least one disc spring is present in the feed cylinder.

[0029] By adopting the above technical solution, as the disc springs are continuously consumed, the counterweight ring drives the guide rod to move continuously downward. When the remaining number of disc springs is almost exhausted, the positioning ring moves down to the cover plate and touches the sensor. The equipment triggers an audible and visual alarm to prompt the operator to replenish the material. At this time, at least one disc spring is still reserved in the cylinder to ensure that the equipment can continue to operate during the replenishment process and will not stop immediately due to material shortage.

[0030] The purely mechanical linkage triggering system ensures the material level threshold is rigidly guaranteed by the length of the guide rod, unaffected by the specifications of the disc springs or the stacking state, resulting in detection accuracy far exceeding that of photoelectric level sensors. The alarm is triggered by the downward movement of the guide rod of the counterweight assembly, eliminating the need for a separate material level detection mechanism. The detection and pressing components are reused, resulting in a simple structure, low cost, and further improved assembly efficiency and quality.

[0031] Optionally, the feeding mechanism includes: A conveyor belt is installed on the machine body and is used to transport the housing, with the housing opening facing downwards; The feeding block is slidably mounted on the machine body and has a storage slot, so that the shell moves onto the storage slot. The feeding block starts to drive the shell located on the storage slot to be misaligned with other shells and prevents subsequent shells from moving forward. The material gripping assembly is used to grip and transport the misaligned housing located on the storage trough to the loading hole.

[0032] By adopting the above technical solution, the conveyor belt continuously conveys the shells with the opening facing downwards to move forward in sequence. After the front shell enters the storage tank, the pusher block slides laterally to push the shell out of the main path of the conveyor line. At the same time, the side wall of the pusher block blocks the subsequent shells from moving forward, realizing the isolation and distribution of single shells. Then the gripping component grabs the shell and accurately puts it into the feed hole of the turntable.

[0033] The staggered material distribution mechanism physically isolates individual housings, completely preventing feeding failures caused by housing stacking and jamming, thus solving the industry pain point of easy jamming during continuous conveyor belt feeding. The continuous feeding of the conveyor belt and the intermittent operation of the turntable are connected by the staggered material distribution mechanism, ensuring that their cycles do not interfere with each other. The conveyor line can operate at a uniform speed without frequent start-stop operations, extending the conveyor belt's lifespan. This purely mechanical staggered material distribution mechanism eliminates the need for complex visual recognition systems, resulting in low cost, low failure rate, and simple maintenance and debugging.

[0034] Optionally, the material gripping assembly includes: The first movable component is radially slidably mounted on the machine body along the feeding tray; The second movable component is vertically slidably mounted on the first movable component; The gripper is mounted on the second moving part and is used to grip the shell.

[0035] By adopting the above technical solution, the first moving part moves horizontally in the radial direction, driving the gripper to switch between the material distribution position and the loading hole position; the second moving part moves vertically up and down to realize the gripping and placement action; the two axes work together to complete the complete loading action of "lowering gripping → rising → horizontal movement → lowering placement → rising reset".

[0036] Optionally, the flipping mechanism includes: The lifting components are mounted on the machine body. The rotating component is mounted on the lifting component and moves vertically under the driving action of the lifting component; The clamping component is mounted on the rotating component and is used to clamp and position the housing. It rotates under the driving action of the rotating component. The lifting component drives the clamping component to move downward, and the clamping component clamps and positions the housing. The lifting component drives the housing to move upward and disengage from the feeding hole. The clamping component drives the housing to flip over. The lifting component drives the housing to move downward and place it on the feeding hole. After the clamping component releases its grip, it moves upward.

[0037] By adopting the above technical solution, after the shell is transferred to the flipping station by the feeding tray, the lifting component drives the rotating component and the clamping component to move downward, and the clamping component clamps the shell; the lifting component moves upward, causing the shell to disengage from the feeding hole; the rotating component drives the clamping component to flip the shell 180°, changing its posture from opening downward to opening upward; the lifting component moves downward, putting the flipped shell back into the same feeding hole; the clamping component is released, and the lifting component drives the mechanism to move upward to reset, waiting for the next flipping.

[0038] In summary, this application includes at least one of the following beneficial technical effects: 1. By integrating five independent processes—shell loading, bottom marking, posture flipping, multi-disc spring stacking, and finished product unloading—into a single rotating machine, the manual transfer and repeated loading and unloading between multiple machines are eliminated, and a single machine can complete the entire production process. The same loading hole can successively support shells with both openings facing down and openings facing up. Marking and assembly share the same set of positioning carriers, eliminating the need to design two sets of independent positioning fixtures, reducing tooling manufacturing costs and changeover debugging time, and improving assembly efficiency and quality.

[0039] 2. By using multiple sets of installation mechanisms independently arranged along the circumference, each station completes the assembly of only a single disc spring. The action logic is simple, the repeatability is high, and the cumulative error caused by reciprocating pressing at a single station is avoided. The concentricity and perpendicularity consistency of multi-piece stacking are significantly improved. This greatly improves assembly efficiency and quality.

[0040] 3. By adopting the posture flow process of "reverse mounting for bottom marking + forward mounting for disc spring", it directly adapts to the industry's common requirement of marking the bottom of the disc spring assembly housing, filling the technical gap of no marking process in turntable disc spring assembly equipment. The turntable's intermittent indexing operation mode has a stable cycle time, and each station can operate in parallel. The capacity demand can be flexibly adapted by adjusting the turntable speed and the number of stations, which is convenient for integration into a fully automated production line, thereby greatly improving assembly efficiency and quality.

[0043] The present application will be further described in detail below with reference to the accompanying drawings.

[0044] This application discloses a disc spring feeding table.

[0045] Example 1, referring to Figure 1 and Figure 2 The disc spring feeding platform includes a machine body 1 and a feeding device 2 installed on the machine body 1. The feeding device 2 first marks the bottom of the housing 11, and then installs multiple disc springs into the housing 11 as required.

[0046] The feeding device 2 includes a feeding tray 21, a feeding mechanism 3, a marking mechanism 22, a flipping mechanism 4, multiple mounting mechanisms 5, and a discharging mechanism 8. The feeding tray 21 is rotatably mounted on the machine body 1, and the axis of rotation is vertical. A servo motor that drives the feeding tray 21 to rotate is fixedly mounted on the machine body 1, thereby driving the feeding tray 21 to rotate. Multiple feeding holes are arranged in a circular array around the axis of the feeding tray 21 on the upper surface of the feeding tray 21. The feeding holes are stepped blind holes. The housing 11 is placed vertically on the feeding holes for positioning, and the top of the housing 11 extends above the feeding tray 21. The feeding mechanism 3, the marking mechanism 22, the flipping mechanism 4, the multiple mounting mechanisms 5, and the discharging mechanism 8 are arranged in a circular array around the axis of the feeding tray 21 and are arranged corresponding to the multiple feeding holes. The above multiple structures are assembled simultaneously as needed.

[0047] The feeding mechanism 3 is used to transport the housing 11 into the feeding hole to achieve feeding, so that the opening of the housing 11 faces downward; the feeding plate 21 rotates to drive the housing 11 to the marking mechanism 22, and the marking mechanism 22 starts to mark the bottom of the housing 11; the housing 11 rotates to the flipping mechanism 4, and the flipping mechanism 4 starts to grab the housing 11, flip it 180 degrees and continue to place it on the feeding hole, so that the opening of the housing 11 faces upward.

[0048] The housing 11 rotates sequentially to multiple mounting mechanisms 5. The multiple mounting mechanisms 5 are activated to install disc springs into the housing 11. Each mounting mechanism 5 installs one disc spring, so the number of mounting mechanisms 5 that are activated can be selected as needed. Multiple disc springs are placed in the mounting mechanism 5 according to the required disc spring direction. Therefore, multiple disc springs can be installed into the housing 11 in the required direction as needed. Finally, the housing 11 rotates to the unloading mechanism 8. The unloading mechanism 8 is activated to grab the housing 11 to unload it, thereby completing the marking of the housing 11 and the assembly of multiple disc springs, improving assembly efficiency and quality.

[0049] Reference Figures 1-4 The feeding mechanism 3 includes a conveyor belt 31, a feeding block 32, and a gripping assembly 33. The conveyor belt 31 is fixedly installed on the machine body 1 and horizontally conveys the housing 11. Two limiting strips 322 are fixedly installed on the machine body 1, which abut against the housing 11 for limiting movement. The movement direction of the housing 11 is along the length direction of the limiting strips 322. A mounting seat extending above the conveyor belt 31 and the feeding plate 21 is fixedly installed on the machine body 1 on the side of the conveyor belt 31 near the feeding plate 21. The feeding block 32... Located on the side of the conveyor belt 31 near the mounting base, the feeding block 32 is horizontally slidably mounted on the machine body 1, and the sliding direction is perpendicular to the length direction of the limiting strip 322. The feeding block 32 abuts against the two limiting strips 322. A storage groove 321 is opened on the side of the feeding block 32 near the conveyor belt 31. An electric push rod for driving the feeding block 32 to move is fixedly installed on the machine body 1. The material gripping assembly 33 is used to grip the housing 11 that has been misaligned and is located on the storage groove 321 and place it on the feeding hole.

[0050] The operator places multiple housings 11 with their openings facing down onto the conveyor belt 31, positioned between two limiting bars 322. The conveyor belt 31 drives the multiple housings 11 to move toward the loading block 32, causing one housing 11 to move onto the storage trough 321. The loading block 32 moves, driving the housing 11 on the storage trough 321 to be misaligned with the multiple housings 11 positioned between the two limiting bars 322, and the loading block 32 abuts against the housing 11 for positioning. The gripping assembly 33 is used to grip and transport the misaligned housing 11 on the storage trough 321 to the loading hole. The loading block 32 moves back, causing the housing 11 to continue moving onto the storage trough 321, and then the above operation is repeated.

[0051] The material gripping assembly 33 includes a first moving part 34, a second moving part 35, and a gripping part 36. Both the first moving part 34 and the second moving part 35 are sliding cylinders. The first moving part 34 is mounted on the top of the first mounting base and slides radially along the feeding tray 21 on the first mounting base. The second moving part 35 is mounted on the first moving part 34 and slides vertically on the first moving part 34. The gripping part 36 is a three-jaw cylinder and is mounted on the second moving part 35, thereby driving the three-jaw cylinder to move in both horizontal and vertical directions. The gripper 36 moves to the top of the housing 11 located on the storage tank 321. After the gripper 36 moves down, it grips the housing 11 located on the storage tank 321. The gripper 36 moves up, driving the housing 11 to move up, so that the housing 11 moves above the feeding hole. The gripper 36 and the housing 11 move down, so that the housing 11 is placed on the feeding hole for positioning. After the gripper 36 releases its grip, it moves up, thereby realizing the gripping and placement of the housing 11 on the feeding hole.

[0052] Reference Figure 2 , Figure 5 The marking mechanism 22 is used to mark the bottom of the housing 11. The marking mechanism 22 is existing technology and will not be described in detail here. The flipping mechanism 4 includes a lifting member 41, a rotating member 42, and a clamping member 43. The lifting member 41 is a sliding cylinder and is vertically arranged. The rotating member 42 is a rotary cylinder and is mounted on the lifting member 41. The clamping member 43 is a clamping cylinder and has two clamping arms, which are mounted on the rotating member 42. The lifting member 41 drives the clamping member 43 to move downward. The clamping member 43 activates to drive the two clamping arms to move closer to each other to clamp and position the housing 11. The lifting member 41 drives the housing 11 to move upward and disengage from the feeding hole. The clamping member 43 drives the housing 11 to flip 180 degrees. The lifting member 41 drives the housing 11 to move downward and place it on the feeding hole. The clamping member 43 releases the clamp and moves upward, thereby flipping the housing 11 180 degrees so that the opening of the housing 11 faces upward, which facilitates the installation of the disc spring.

[0053] Reference Figure 2 , Figures 6-9 The installation mechanism 5 includes a push plate 51, a feeding assembly 6, a push rod 52, an elastic push assembly 7, and a detection component 53. A second mounting base is fixedly installed on the machine body 1. The length direction of the second mounting base is parallel to the radial direction of the feeding tray 21. A support frame is fixedly installed on the upper surface of the second mounting base. The support frame is gantry-shaped and has a limiting surface 57 located above the second mounting base. The push plate 51 slides along the length direction of the second mounting base and is installed on the upper surface of the second mounting base. An electric push rod that drives the push plate 51 to move is fixedly installed on the second mounting base. The push plate 51 passes through the support frame. A placement groove 54 is opened on the upper surface of the push plate 51 near the feeding tray 21. The placement groove 54 passes through the end of the push plate 51 near the feeding tray 21, and a vertical through insertion hole 56 is opened at the bottom of the groove.

[0054] The feeding assembly 6 is installed on the upper surface of the support frame and is used to stack multiple disc springs as required. It is used to limit the disc springs so that the lowest disc spring is placed on the placement groove 54 and its top extends above the push plate 51. The feeding assembly 6 includes a feeding cylinder 61 and a cover plate 62. The feeding cylinder 61 is fixedly installed on the upper surface of the support frame and is in a vertical state. The disc springs are stacked and placed in the feeding cylinder 61. At the same time, the lowest disc spring moves down under its own weight and the weight of the disc springs above it and is placed in the placement groove 54 for positioning.

[0055] A vertical mounting base 3 is fixedly installed on the upper surface of the support frame. A cover plate 62 is rotatably installed on the top of the mounting base 3. A rotating cylinder 63 with a vertically upward piston rod is fixedly installed on the mounting base 3. A connecting rod that is rotatably connected to the cover plate 62 is rotatably installed on the piston rod of the rotating cylinder 63. The rotating cylinder 63 drives the cover plate 62 to rotate to a vertical position, thereby opening the feeding cylinder 61. The rotating cylinder 63 drives the cover plate 62 to rotate to a horizontal position, and the cover plate 62 abuts against the top of the feeding cylinder 61 to seal it.

[0056] A vertically positioned slide cylinder is fixedly installed on the upper surface of the support frame and on the side of the feeding cylinder 61 near the feeding tray 21; the push rod 52 is fixedly installed on the piston rod of the slide cylinder, the slide cylinder drives the push rod 52 to move vertically, and the push rod 52 and the feeding hole are coaxially arranged, while the push rod 52 slides vertically through the support frame and extends below the limiting surface 57.

[0057] The elastic pusher assembly 7 is located on the pusher rod 52 and is elastic; the pusher rod 52 has a vertical pusher groove 55. The elastic pusher assembly 7 includes a pusher block 71 and an elastic element 72. The pusher block 71 is vertically slidably installed on the pusher groove 55, and one end extends to the outside of the pusher groove 55. The elastic element 72 is a spring. The elastic element 72 is located above the pusher block 71, with its bottom end fixedly installed on the upper surface of the pusher block 71 and its top end pressing against the top of the pusher groove 55.

[0058] Before the push rod 52 moves down, i.e. in the initial state, the push block 71 is positioned by pressing against the bottom of the push groove 55 under the elastic force of the elastic element 72. The detection element 53 is fixedly installed on the upper surface of the support frame and is located on the side of the push rod 52 near the loading tray 21, horizontally facing the push rod 52. The detection element 53 is used to detect the position of the push block 71.

[0059] The disc spring at the lowest point moves down to the placement slot 54. The push plate 51 pushes the disc spring in the placement slot 54 to move below the push rod 52, so that the disc spring and the push rod 52 are aligned. During the movement of the disc spring, the limiting surface 57 prevents the disc spring from moving up and disengaging from the placement slot 54. The push rod 52 moves down, passes through the disc spring, and extends into the housing 11. At the same time, it pushes the elastic push assembly 7 down, so that the push block 71 presses against the disc spring for positioning. The detection element 53 detects the push block 71 and therefore determines that the disc spring is present. The push plate 51 moves back and causes the disc spring to disengage from the placement slot 54 under the restriction of the push rod 52. The disc spring is installed into the housing 11 under the elastic force of the elastic push assembly 7 and the guiding action of the push rod 52. After the push rod 52 and the elastic push assembly 7 move up, the feeding tray 21 rotates.

[0060] If no disc spring is placed in the placement slot 54, the pusher block 71 moves down through the insertion hole 56 under the action of the elastic force. If the detection element 53 does not detect the pusher block 71, the above action continues to repeat, adding disc springs to the placement slot 54 until the detection element 53 detects the disc springs. After the disc springs are installed, the loading tray 21 rotates again. The bottom end of the pusher rod 52 has a guide angle to facilitate the passage of the disc springs.

[0061] Reference Figure 2 , Figure 10 The unloading mechanism 8 includes a conveyor line 81 and a material handling component 82. The conveyor line 81 is fixedly installed on the machine body 1 and horizontally conveys the housing 11. A mounting base 4 extending above the conveyor line 81 and the loading tray 21 is fixedly installed on the machine body 1 on the side of the conveyor line 81 near the loading tray 21. The material handling component 82 is used to grab the assembled housing 11 located on the loading hole and place it on the conveyor line 81. The conveyor line 81 conveys the housing 11 away from the loading tray 21, and then the operator or robot can remove the housing 11. At the same time, the material handling component 82 and the material handling component 33 have the same structure.

[0062] The working principle of this application embodiment is as follows: The feeding mechanism 3 is used to transport the housing 11 into the feeding hole to achieve feeding, so that the opening of the housing 11 faces downward. The marking mechanism 22 is started to mark the bottom of the housing 11. The flipping mechanism 4 is started to grab the housing 11, flip it over and continue to place it on the feeding hole, so that the opening of the housing 11 faces upward.

[0063] The housing 11 rotates sequentially to multiple mounting mechanisms 5. The multiple mounting mechanisms 5 are activated to install disc springs into the housing 11. Each mounting mechanism 5 installs one disc spring, so the number of mounting mechanisms 5 that are activated can be selected as needed. Multiple disc springs are placed in the mounting mechanism 5 according to the required disc spring direction. Therefore, multiple disc springs can be installed into the housing 11 in the required direction as needed. Finally, the housing 11 rotates to the unloading mechanism 8. The unloading mechanism 8 is activated to grab the housing 11 to unload it, thereby completing the marking of the housing 11 and the assembly of multiple disc springs, improving assembly efficiency and quality.

[0064] Example 2, refer to Figure 6 , Figures 11-12 The difference between this embodiment and embodiment 1 is that a clearance groove 64 is provided on the cover plate 62 on the side away from the rotating cylinder 63, and a counterweight mechanism 9 is also included. The counterweight mechanism 9 is used to position the disc spring under the action of gravity.

[0065] The counterweight mechanism 9 includes a counterweight ring 91, a guide rod 92, an elastic plate 93, and an alarm component 94. The outer diameter of the counterweight ring 91 is the same as the outer diameter of the disc spring, and the counterweight ring 91 is positioned by pressing against the disc spring under the action of gravity. A counterweight hole is coaxially opened on the counterweight ring 91, and the guide rod 92 is coaxially slidably installed on the counterweight hole. One end of the guide rod 92 is provided with a first locking groove 921, and the other end is provided with a second locking groove 922. The elastic plate 93 is fixedly installed on the upper surface of the counterweight ring 91, and is locked in the first locking groove 921 or the second locking groove 922 for positioning under the action of elastic force.

[0066] The alarm component 94 is used to issue an alarm when the number of disc springs in the feeding cylinder 61 is less than a specified number. The alarm component 94 includes a positioning ring 95 and a sensor 96. The positioning ring 95 is coaxially fixedly installed on one end of the guide rod 92 near the second snap-fit ​​groove 922 and is used to drive the guide rod 92 to move. The sensor 96 is fixedly installed on the cover plate 62, and an audible and visual alarm is fixedly installed on the support frame. The audible and visual alarm is controlled to start and stop through the control box, and the control box is electrically connected to the sensor 96.

[0067] When placing disc springs, the end of the guide rod 92 with the first snap-fit ​​groove 921 is vertically upward, and the elastic piece 93 is disengaged from the first snap-fit ​​groove 921. The guide rod 92 is pushed upward until the elastic piece 93 is snapped into the second snap-fit ​​groove 922 for positioning. Then, multiple disc springs are slid onto the guide rod 92 and placed on the upper surface of the counterweight ring 91 for positioning. The disc springs are held for positioning, and the end of the guide rod 92 with the first snap-fit ​​groove 921 is vertically downward. The multiple disc springs are then vertically stacked and placed into the feeding cylinder 61. The disc spring at the lowest position falls downward into the placement groove 54. At the same time, the positioning ring 95 is held and moved downward to drive the counterweight ring 91 to move downward into the feeding cylinder 61. The positioning ring 95 is located above the feeding cylinder 61. The cover plate 62 rotates and abuts against the top of the feeding cylinder 61 for positioning, so that the guide rod 92 is located in the relief groove 64.

[0068] Pull the guide rod 92 and the counterweight ring 91 upwards, so that the counterweight ring 91 abuts against the cover plate 62 and stops moving upwards. Move the elastic piece 93 away from the second locking groove 922. The guide rod 92 moves upwards until the bottom of the guide rod 92 moves into the counterweight hole. Release the elastic piece 93 so that the elastic piece 93 is locked in the first locking groove 921 for positioning. Under the action of its own weight, the guide rod 92 and the positioning ring 95, the counterweight ring 91 presses against the disc spring at the highest point for positioning.

[0069] As the number of disc springs in the feeding cylinder 61 decreases, the counterweight ring 91 drives the guide rod 92 and the positioning ring 95 to move downwards until the positioning ring 95 presses against the sensor 96. At this time, there is still at least one disc spring in the feeding cylinder 61. The specific number can be set as needed. At the same time, the audible and visual alarm is activated to remind the staff to pull the positioning ring 95 to drive the guide rod 92 upwards, and the cover plate 62 rotates away from the feeding cylinder 61, so that the counterweight ring 91 can be removed to continue installing the disc springs.

[0070] The working principle of this application embodiment is as follows: With one end of the guide rod 92 having a snap-fit ​​groove 921 facing upwards, the elastic piece 93 is disengaged from the snap-fit ​​groove 921, pushing the guide rod 92 upwards so that the elastic piece 93 is snapped into the snap-fit ​​groove 922 for positioning; multiple disc springs are slid onto the guide rod 92 for positioning, and the disc springs are held for positioning. With one end of the guide rod 92 having a snap-fit ​​groove 921 facing downwards, multiple disc springs are vertically stacked and placed inside the feeding cylinder 61. The disc spring at the lowest position falls downwards onto the placement groove 54, causing the counterweight ring 91 to move down into the feeding cylinder 61. The cover plate 62 rotates and abuts against the top of the feeding cylinder 61 for positioning, so that the guide rod 92 is located on the clearance groove 64.

[0071] Pull the guide rod 92 and the counterweight ring 91 upwards, so that the counterweight ring 91 abuts against the cover plate 62. Move the elastic piece 93 to disengage from the second locking groove 922. The guide rod 92 moves upwards into the counterweight hole. The elastic piece 93 is locked in the first locking groove 921 for positioning. Under the gravity of itself, the guide rod 92 and the positioning ring 95, the counterweight ring 91 presses against the disc spring at the highest point for positioning.

[0072] As the number of disc springs in the feeding cylinder 61 decreases, the counterweight ring 91 drives the guide rod 92 and the positioning ring 95 to move downwards until the positioning ring 95 presses against the sensor 96. At this point, there is still at least one disc spring in the feeding cylinder 61. The audible and visual alarm is activated to remind the operator to pull the positioning ring 95 to drive the guide rod 92 upwards, and the cover plate 62 rotates away from the feeding cylinder 61. This allows the counterweight ring 91 to be removed to continue installing the disc springs, thereby improving the accuracy of disc spring placement and increasing assembly efficiency and quality.

[0073] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
