Description

Technical Field

[0001] This invention relates to the field of automatic assembly technology, and in particular to an automatic assembly equipment for shock absorbers. Background Technology

[0002] Shock absorbers are used to suppress the oscillations caused by the rebound of springs after absorbing shocks, as well as impacts from the road surface. They are widely used in automobiles to accelerate the attenuation of vibrations in the chassis and body, thereby improving the ride comfort of the vehicle.

[0003] When driving over uneven roads, although shock-absorbing springs can filter out road vibrations, the springs themselves still undergo reciprocating motion. Shock absorbers are used to suppress this spring bounce. If the shock absorbers are too soft, the car body will bounce up and down; if the shock absorbers are too stiff, they will create too much resistance, hindering the normal operation of the springs. In the process of modifying the suspension system, stiff shock absorbers must be matched with stiff springs, and the stiffness of the springs is closely related to the vehicle's weight. Therefore, heavier vehicles generally use stiffer shock absorbers.

[0004] However, in the existing technology, the production of shock absorbers still uses belt conveyors and / or turnover carts to transport them to the manual workstations, and then mass production is carried out by manual assembly.

[0054] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0055] Embodiment 1:

[0056] Referring to Figures 1-11 An automatic shock absorber assembly line, wherein the shock absorber 800 has a tube body 802 and a piston rod 801, the assembly line comprises:

[0057] A leakage detection station 100 for inflating the piston rod 801 of the shock absorber 800;

[0062] A dust ring pressing station 600 for pressing the dust ring into a fixed position between the piston rod 801 and the tube body 802;

[0063] The leakage detection station 100, the oil injection station 200, the dust ring loading station 300, the spring loading station 400, the cap mounting station 500, and the dust ring pressing station 600 are arranged in sequence along the material conveying direction.

[0064] Compared with the traditional assembly line, the automatic assembly line of the present application greatly improves the work efficiency, reduces the labor cost, and ensures the product quality.

[0065] The assembly line is externally provided with a protective cover 40 to avoid safety hazards during work and prevent external environmental interference from affecting the internal operation.

[0066] The dust ring loading station 300 and the spring loading station 400 share the same fixed station, and the two installation actions are performed separately, sequentially, and without interference.

[0067] As Figure 2 shown in one of the embodiments, the leakage detection station 100 comprises an inflation claw 101, a rear of the inflation claw 101 is provided with an inflation cylinder 103, the inflation cylinder 103 can control the inflation claw 101 to open and close, an inflation component 102 is arranged above the inflation claw 101, when the shock absorber 800 is fixed on the inflation claw 101, the inflation component 102 moves downward to inflate the shock absorber 800.

[0068] Specifically, the shock absorber 800 has a process of inflating in production, and the shock absorber is sealed after being inflated. The shock absorber has a part of gas inside, and the gas will be compressed when the shock absorber is pressed down and then slowly rebound. Generally, if the gas does not rebound, it means that the gas leaks, and liquid may leak. If the gas leaks, it will affect the performance of the shock absorber. As the first process of the device, the shock absorber 800 is placed into the inflation claw 101 by manual operation, the inflation part 102 is controlled to be pressed down for inflation, and the lower part of the inflation part in the scheme is made of soft rubber material, which is beneficial to create a sealed environment for the shock absorber 800 during extrusion and inflation, so as to prevent the gas from leaking at the inflation end during the inflation process and cause the shock absorber to be unable to be accurately judged as qualified. The gas pressure gauge is also arranged at the position, and the gas leakage can be visually observed through the gas pressure gauge, so that the gas leakage can be found in time and repaired in time.

[0069] Specifically, the gas leakage detection station in the embodiment has three inflation claws, and is matched with three sets of inflation parts. The inflation claws play a role in improving assembly efficiency and effectively speeding up the working rhythm.

[0070] The inflation claw 101 can be an electric control clamp or a gas control clamp, and its main function is to fix the shock absorber 800. When the inflation detection is completed, the oil injection manipulator 104 will move to the lower side of the inflation claw 101, clamp the shock absorber 800 after the inflation detection, and transport the shock absorber 800 to the oil injection station 200.

[0071] In one embodiment, the oil injection station 200 is provided with an oil injection pipe 201, the oil injection pipe 201 is provided below the moving track 106, the moving track 106 is provided with a sliding seat one 105, the bottom of the sliding seat one 105 is provided with a power component, so that the sliding seat one 105 can move left and right on the moving track 106; the sliding seat one 105 is provided with an oil injection manipulator 104, and the oil injection manipulator 104 can take down the shock absorber 800 on the gas leakage detection station 100 and transport it to the oil injection pipe 201 to be connected with the oil injection pipe 201.

[0072] Specifically, in the embodiment, the moving track 106 is provided with a lead screw, the sliding seat one 105 is threadedly connected with the lead screw, and the outer end of the lead screw is connected with a rotating component, such as a servo motor, a stepping motor, a hydraulic motor or the like. In the embodiment, the lead screw is preferably a rectangular lead screw, which has high transmission accuracy and is beneficial to accurately positioning and grabbing the shock absorber 800.

[0073] The sliding seat two 107 is slidably connected with the moving track 106, the bottom of the sliding seat two 107 is provided with a driving component, so that the sliding seat two 107 can move on the moving track 106, and the sliding seat two 107 is provided with a three-station manipulator 108, which is used for simultaneously clamping three shock absorbers 800 of adjacent stations and conveying them to the rear station.

[0074] Specifically, the second sliding seat 107 is also slidingly connected with the moving track 106. In the embodiment, the driving part of the second sliding seat 107 is located at the bottom of the moving track 106, which can be a cylinder, a hydraulic cylinder or the like, and the second sliding seat 107 moves back and forth on the moving track 106 by pushing and pulling;

[0075] The second sliding seat 107 is provided with a three-station mechanical arm 108. The three-station mechanical arm 108 is actually three clamps installed together and moves with the second sliding seat 107. When the work of the previous station is completed, the three clamps of the three-station mechanical arm 108 move forward by one station (i.e., the frontmost clamp moves to the oil injection station 200), grab the shock absorber 800 of the adjacent three stations, and then retreat by one station, i.e., simultaneously carry the front three stations back by one station, so as to make up for the vacancy caused by the flow of the rear stations due to the completion of the work. The three-station mechanical arm 108 functions to move back and forth between the oil injection station 200, the dustproof ring loading station 300, the plug cover installation station 500 and the total length detection station 900.

[0076] In one embodiment, the dustproof ring loading station 300 is provided with a vibrating disc 301 outside, the vibrating disc 301 is used to load and deliver the dustproof ring, and a dustproof ring mechanical arm 302 is arranged above the vibrating output end, the dustproof ring mechanical arm 302 can grab the dustproof ring delivered by the vibrating disc 301 and set the dustproof ring on the piston rod 801 of the shock absorber 800 in the dustproof ring loading station 300.

[0077] Specifically, the dustproof ring mechanical arm 302 is composed of multiple groups of cylinders and has the functions of moving forward and backward and moving up and down. The dustproof ring mechanical arm 302 has clamps at the ends, which can clamp the dustproof ring and put it on the piston rod 801 of the dustproof ring loading station 300.

[0078] In the embodiment, the output end of the vibrating disc 301 is provided with a photoelectric sensor. When the photoelectric sensor senses the dustproof ring, the vibrating disc 301 immediately stops vibrating, and the dustproof ring mechanical arm 302 grabs the dustproof ring. This effectively avoids the continuous vibration of the vibrating disc 301, which causes the continuous output of the dustproof ring.

[0079] In one embodiment, the spring loading station 400 is provided with a spring feeding seat 401 on one side, the spring feeding seat 401 is provided with a spring mechanical arm 402 above, and the spring mechanical arm 402 can grab the spring in the spring feeding seat 401 and move it to the shock absorber 800 of the spring loading station 400, and then load the spring into the piston rod 801.

[0080] The spring mechanical arm 402 can grab the spring in the spring feeding seat 401 and move it to the shock absorber 800 of the spring loading station 400, and then load the spring into the piston rod 801.

[0081] Specifically, in this embodiment, the spring loading seat 401 has a clamping groove on both sides, and the clamping jaw of the spring manipulator 402 is provided with a clamping jaw matched with the clamping groove. When the spring manipulator 402 clamps, the clamping jaw at the lower end of the spring manipulator 402 clamps on the clamping groove of the spring loading seat 401, and the spring is clamped and carried.

[0082] In one embodiment, one side of the cap mounting station 500 is provided with a cap feeding belt 501, the cap feeding belt 501 is a belt structure with conveying capacity, one end of the cap feeding belt 501 is provided with a positioning part 502, the positioning part 502 is used for positioning the cap output by the cap feeding belt 501, and the positioning part 502 is provided with a cap manipulator 503 above, the cap manipulator 503 can grab the cap moved to the positioning part 502 and move to the piston rod 801 of the shock absorber 800 at the cap mounting station 500, and the cap is screwed into the piston rod 801.

[0083] In one embodiment, the air leakage detection station, the spring mounting station and the cap mounting station are arranged in an L shape, so that one installer can operate the three mounting stations at the same time, for example, the shock absorber can be placed in the inflation claw, the spring can be loaded into the spring loading seat, and the cap can be placed on the cap feeding belt.

[0084] In this embodiment, the positioning part 502 not only has the function of positioning, but also has the function of anti-interference. Specifically, the positioning part 502 is provided with a cylinder, and the front end of the cylinder is provided with a wedge. After the frontmost cap is positioned, the cylinder drives the wedge to separate the rear cap from the front positioned cap, so that when the cap manipulator 503 clamps the positioned cap, interference to the rear cap is avoided. In this scheme, the end of the cap manipulator 503 has an internal hexagonal groove (not shown in the figure) and has a magnetic attraction ability. When working, the cap is sleeved in the internal hexagonal groove and magnetically attracted, and then moved to the cap mounting station 500. Through rotation, the internal hexagonal groove drives the cap to be screwed into the piston rod 801 of the shock absorber 800, achieving the effect of automatic installation.

[0085] In one embodiment, the head cover mounting station 500 is followed by a total length detection station 900, which has a total length detection device, including: a fixed end 901 for fixing the piston rod 801 of the shock absorber 800 transported to the station, and a lifting detection mechanism below the fixed end 901, including: a lifting seat 902, which has a lifting lead screw 903 inside, and a lifting sliding block 904 above the lifting lead screw 903, which is in sliding connection with the lifting seat 902, and a lifting motor connected with the lifting lead screw 903 at the upper end of the lifting seat 902, for driving the lifting sliding block 904 to move up and down, and a connecting plate 905 above the lifting sliding block 904, and a pressure sensor 906 above the connecting plate 905, which, when working, is controlled to abut against the lower end of the shock absorber 800 and move upward, for detecting the total length of its installation and testing its damping at the same time.

[0086] In one embodiment, the pressure sensor 906 includes: an upper part and a lower part, which are movable in the vertical direction; both the upper part and the lower part are provided with conductors, when the lead screw rotates and the lower end of the shock absorber abuts against the upper part, the upper part is forced to continue moving downward, the upper part continues to abut against the lower part when it moves downward, the conductors are connected and a contact signal is generated, then the length of the shock absorber is obtained by comparing the number of turns of the lead screw with a reference value; and the total length and damping of the shock absorber 800 at the station are comprehensively judged to be qualified or not by using the damping value measured by the pressure sensor 906.

[0087] In one embodiment, the dust ring pressing station 600 includes: a fixed cylinder 601, which has a fixed hole 602 corresponding to the piston rod 801 inside, and a tapered surface 603 above the fixed hole 602;

[0088] The fixed cylinder 601 has a pressing mechanism above, which includes: a pressing cylinder 604 and a pressing rod 605, and the pressing rod 605 is connected to the lower end of the pressing cylinder 604, when working, the piston rod 801 of the shock absorber 800 is installed in the fixed hole 602, and then the pressing rod 605 is used to extrude the end of the pipe body 802 to press and fix the dust ring;

[0089] One side of the dust ring pressing station 600 is provided with a discharging mechanism 10, which is used to take the shock absorber 800 from the total length detection station 900, rotate it by 180°, move it above the fixed cylinder 601, and put it into the fixed hole 602 of the dust ring pressing station 600;

[0090] Specifically, in the embodiment, the fixed cylinder 601 is rotatably connected with the bottom, the fixed cylinder 601 is provided with a gear in the circumferential direction, one side of the gear is provided with a rack in meshing connection, and the rear of the rack is provided with a push-pull component such as an electric cylinder, a pneumatic cylinder and the like. In work, the push-pull component is controlled to drive the rack to move, thereby driving the gear to rotate, and the fixed cylinder rotates together, so as to adjust the circumferential position of the fixed cylinder 601. The purpose is that when the dust cover is not pressed well at this station, the dust cover can be continuously pressed from another direction until the dust cover is completely pressed.

[0091] The discharging mechanism 10 comprises a fixed table 11, a sliding seat three 12 is slidably connected to the fixed table 11, a lifting table 13 is arranged above the sliding seat three 12, a jacking cylinder 14 is arranged between the sliding seat three 12 and the lifting table 13, an extending cylinder 15 is arranged on the lifting table 13, a rotating cylinder 16 and a pneumatic clamp jaw 17 are sequentially arranged at the front end of the extending cylinder 15.

[0092] In work, the pneumatic clamp jaw 17 clamps the piston rod 801 of the shock absorber 800, and the rotating cylinder 16 on the discharging mechanism 10 controls the pneumatic clamp jaw 17 to overturn the shock absorber 800 by 180°, and inserts the piston rod 801 into the fixing hole 602 of the fixed cylinder 601, so that the dustproof ring abuts on the conical surface 603, facilitating the extrusion work of the dustproof ring in the next station.

[0093] In one embodiment, one side of the fixed cylinder 601 is provided with a lifting mechanism 30, the lifting mechanism 30 comprises a lifting cylinder 31, a supporting plate 32 is connected to the lower end of the lifting cylinder 31, a jacking groove 33 is arranged on the fixed cylinder 601 and communicates with the fixing hole 602, and the supporting plate 32 extends into the fixing hole 602 through the jacking groove 33.

[0094] As shown in Figure 10 Specifically, the supporting plate 32 extends into the fixed cylinder 601 through the jacking groove 33 to seal the fixing hole 602 in the fixed cylinder 601, after the pressing work of the dust cover is completed, the piston rod 801 of the shock absorber 800 is lifted to a set height by the lifting cylinder 31, so that the taking mechanism can directly clamp the piston rod 801, because the models of the shock absorber 800 are various, the sizes and shapes of the shock absorber 800 pipes 802 of different models are different, but the shape and size of the piston rod 801 are generally uniform, so that the taking mechanism can be universal and is not affected by the model switching.

[0095] In one of the embodiments, a conveying station 700 is further included, which is arranged behind the dust ring pressing station 600. The conveying station 700 comprises a chain conveying mechanism 701, and a plurality of conveying cylinders 702 are uniformly arranged on the chain of the chain conveying mechanism 701. The conveying cylinders 702 are used for inserting the piston rod 801 of the shock absorber 800.

[0096] One side of the conveying station 700 is provided with a loading mechanism 20, which is provided with a loading manipulator. The loading manipulator takes out the shock absorber 800 with the pressed dust ring from the fixing cylinder 601, transfers it to the conveying station 700, and then loads it into the conveying cylinder 702. The chain drives the conveying cylinder 702 to convey outward.

[0097] Specifically, the front end and the rear end of the chain conveying mechanism 701 are both provided with photoelectric sensors. When the first conveying cylinder 702 at the front end is loaded with the shock absorber 800, the photoelectric sensor at the front end will sense the presence of the shock absorber 800 and give a signal to control the chain conveying mechanism 701 to move backward by a distance of one conveying cylinder 702. When the photoelectric sensor at the rear end of the chain conveying mechanism 701 senses the presence of the shock absorber 800, it will also give a signal to control the chain conveying mechanism 701 to stop working. The photoelectric sensor at the rear end has a higher priority than the photoelectric sensor at the front end, which ensures the automatic conveying of the shock absorber 800 and effectively avoids the risk of falling due to conveying to the end.

[0098] The conveying cylinders at the input end of the chain conveying mechanism 701 are provided with positioning clamps on both sides. The positioning clamps are used to position the conveying cylinders to prevent the chain from loosening during long-term movement and causing the position of the conveying cylinder 702 to deviate. When the conveying cylinder 702 reaches the input end, the positioning clamps will extend from both sides to position and adjust the conveying cylinder 702 by extrusion and clamping, so as to ensure that the piston rod 801 of the shock absorber 800 can be accurately loaded therein.

[0099] Please refer to Figure 11 , the working process of the gas spring automatic assembly line in the embodiment of the application will be described below:

[0100] Place a plurality of shock absorbers 800 on the air leakage detection station 100. Control the inflation claw 101 to clamp and fix the shock absorber 800, and then use the inflation component 102 to inflate the shock absorber 800.

[0101] The oil injection manipulator 104 moves on the moving rail 106, grabs the inflated shock absorber 800 to the oil injection station 200, and lifts the piston rod 801 to connect with the oil injection pipe 201. The clamping hand on the oil injection pipe 201 clamps the shock absorber 800, and the oil injection pipe 201 sprays oil into the piston rod 801.

[0102] The vibration disc 301 transports the dustproof ring to the outlet, and stops vibrating when the dustproof ring is in place through photoelectric sensor induction; the dustproof ring manipulator 302 grabs the dustproof ring in place and sets it on the piston rod 801 of the shock absorber 800 on the dustproof ring loading station 300;

[0103] The spring is manually loaded on the spring loading seat 401, and the spring manipulator 402 moves above the spring loading seat 401 to clamp the spring into the piston rod 801 on the spring loading station 400.

[0104] The nipple cover loading belt 501 transports the nipple cover to the positioning part 502, which accurately positions the nipple cover; the nipple cover manipulator 503 moves above it to clamp the nipple cover onto the piston rod 801 of the shock absorber 800 on the nipple cover installation station 500, and the motor on the nipple cover manipulator 503 screws the nipple cover into the piston rod 801, completing the installation of the nipple cover.

[0105] The shock absorber 800 with the installed nipple cover is moved to the total length detection station 900 by the three-station manipulator 108, and the total length of the shock absorber 800 is detected by the total length detection device to determine whether it is qualified, and the pressure sensor 906 is used to test whether the damping is qualified.

[0106] The discharge mechanism 10 clamps the shock absorber 800 from the previous station and flips 180°, and loads it into the fixed cylinder 601 of the dustproof ring compression station 600, so that the piston rod 801 cooperates with the fixed hole 602; the compression cylinder 604 pushes the compression rod 605 to compress the dustproof ring into the pipe body 802.

[0107] The lifting mechanism 30 lifts the piston rod 801 inserted into the fixed hole 602 to a set height by the lifting cylinder 31 driving the supporting plate 32, and the piston rod 801 exposed outside the fixed cylinder 601 is clamped by the loading mechanism 20 (because different shock absorbers 800 have different pipe body 802 sizes and different shaped structures, clamping the piston rod 801 effectively improves the versatility of clamping different models of shock absorbers 800); the shock absorber 800 is moved to the transportation station 700, and the piston rod 801 is inserted into the transportation cylinder 702 on the chain conveyor for backward transportation.
