[0002] The hydraulic shock absorber mainly includes a storage tube, a piston and a piston rod. The interior of the storage tube is filled with liquid oil, and a valve plate for controlling the flow of the liquid oil is provided on the piston. In the traditional shock absorber assembly process, the valve plate and the piston are mostly assembled manually. Since the thickness of various valve plates is 0.1 to 0.3 mm, a certain number of valve plates of certain specifications need to be assembled during the assembly process, and there are strict regulations for a single type of valve plate. Manual assembly is prone to multiple valve plates, missing valve plates or wrong valve plates, which may cause the shock absorber to fail in subsequent tests, affecting the production efficiency and quality of the shock absorber.

[0003] The valve plate sorting machine is a device used for automatic assembly of hydraulic shock absorbers. In fact, it combines the preset number and type of valve plates with the piston on the piston. The piston with the combined valve plates enters the next process and is assembled on the piston rod.

[0004] For example, the utility model with publication number CN220077582U discloses a valve plate rotary sorting line, comprising: a frame 1 arranged in a frame structure, a movable track arranged in a U-shape is installed on the frame 1, a plurality of material receiving members 2 for carrying the workpieces to be processed are installed in the movable track, and a pushing cylinder for pushing the material receiving members 2 to move in the movable track is installed on the frame 1. The number of the pushing cylinders is set to four, and the four pushing cylinders are distributed at the four corners of the movable track. The material receiving members 2 are moved in the movable track through the pushing action of the pushing cylinders.

[0005] This method of using a U-shaped moving track to transport the material receiving member 2 occupies a large horizontal space. The material receiving member 2 has to fill the track, the material receiving member 2 is used in large quantities, and the rotary conveying efficiency is not high.

[0035] The following will be combined with the drawings in some embodiments of the present application to clearly and completely describe the technical solutions in some embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0036] The technical solution of the embodiments of the present application is described in detail below with reference to the accompanying drawings.

[0037] like Figure 1 The figure shows a schematic diagram of the structure of a slide plate 91, which includes a base 911 and a discharge rod 912. When the slide plate 91 moves on the track 11, a certain number of valve plates 93 are first inserted into the discharge rod 912, and then into the piston 92, and finally a certain number of valve plates 93 are inserted above the piston 92. When the slide plate 91 passes through a workstation, a valve plate 93 is inserted into the discharge rod 912, so as to select and control the number of valve plates 93 above and below the piston 92.

[0038] like Figures 2 to 6As shown in the figure, in this embodiment, a slide plate rotary conveying device of a valve sheet sorting machine is provided, which includes a track 11 for moving a slide plate 91, a push cylinder 12 arranged at the front end of the track 11, and a conveying line 21 arranged below the track 11, a first lifting assembly 31 is arranged at the rear end of the conveying line 21, and a second lifting assembly 32 is arranged at the front end of the conveying line 21;

[0039] The first lifting assembly 31 is used to lift the slide 91 on the conveyor line 21 to the front end of the track 11, the pushing cylinder 12 is used to push the slide 91 on the first lifting assembly 31 into the track 11 and move the slide in the track 11 forward, and the second lifting assembly 32 is used to receive the slide 91 at the rear end of the track 11 and then descend and place it on the conveyor line 21.

[0040] Since the conveyor line 21 is arranged below the track 11, the horizontal occupied area is reduced. Compared with the track 11, the conveying effect of the conveyor line 21 is faster, and the usage of the slide 91 is reduced. The slide 91 is transferred between the track 11 and the conveyor line 21 through the first lifting assembly 31 and the second lifting assembly 32.

[0041] In this embodiment, the first lifting assembly 31 includes a mounting plate 311, a lifting platform 312 and a first cylinder 313. The lifting platform 312 is arranged on the mounting plate 311 through a linear guide 314 for movement. The first cylinder 313 is arranged on the mounting plate 311 and connected to the lifting platform 312. The first cylinder 313 drives the lifting platform 312 to move up and down. The upper end surface of the lifting platform 312 is provided with a magnetic part 315, and the magnetic part 315 is a magnet. The slide plate 91 is made of a metal material that can be attracted by magnetism. The slide plate 91 can also be made of plastic and provided with a metal plate that can be attracted by magnetism. The magnetic part 315 is used to magnetically adsorb the slide plate 91 to prevent the slide plate 91 from falling off the lifting platform 312 during the lifting process.

[0042] In this embodiment, the second lifting assembly 32 has the same structure as the first lifting assembly 31 .

[0043] In this embodiment, the conveyor line 21 includes two conveyor belts 211 that are spaced apart and move synchronously, side baffles 212 located on both sides of the conveyor belt 211, and a motor 213 for driving the conveyor belt 211. The conveyor belt 211 is arranged on the side baffles 212 through a plurality of pulleys 214. The motor 213 is arranged on the side baffles 212 and is in transmission connection with at least one pulley 214.

[0044] The mounting plate 311 is arranged on the side baffle 212, and the lifting platform 312 is located between the two conveyor belts 211. When the lifting platform 312 of the first lifting assembly 31 rises, the slide plate 91 located on the conveyor belt 211 is lifted up, so that the slide plate 91 leaves the conveyor belt 211. When the lifting platform 312 of the first lifting assembly 31 descends with the slide plate 91, the slide plate 91 is blocked by the two conveyor belts 211 and thus leaves the lifting platform 312 and remains on the conveyor belt 211.

[0045] In this embodiment, in order to prevent the slide plate from falling sideways when moving on the conveyor belt 211, a guide strip 215 is also provided on the inner side of the side baffle 212. The guide strip 215 is located above the conveyor belt 211 and is used to limit the slide plate 91 on the conveyor belt 211.

[0046] In this embodiment, limit blocks 216 are respectively provided at both ends of the conveyor line 21, and the limit blocks 216 are provided on the side baffles 212. The limit blocks 216 are used to block the slide 91 on the conveyor belt 211. The conveyor line 21 also includes a detection sensor 217 provided on the side baffles 212, and the detection sensor 217 is used to detect whether there is a slide 91 above the first lifting assembly 31.

[0047] The limit baffle at the front end of the conveyor line 21 prevents the slide plate 91 from falling out, and the limit block 216 at the rear end blocks the slide plate 91 from being above the first lifting assembly 31. When the detection sensor 217 senses the presence of the slide plate 91, the first cylinder 313 of the first lifting assembly 31 starts to work, driving the lifting platform 312 to rise and lift up the slide plate 91.

[0048] In this embodiment, in order to enable the slide 91 to enter or leave the track 11, a first opening 111 is provided at the front end of the track 11, and a second opening 112 is provided at the rear end of the track 11. The first opening 111 and the second opening 112 are both provided on the bottom surface of the track 11. The slide 91 rises through the first opening 111 to enter the track 11, and the slide 91 descends through the second opening 112 to leave the track 11.

[0049] When the lifting platen 312 of the first lifting assembly 31 rises with the slide plate 91, it passes through the first opening 111 so that the upper end surface of the lifting platen 312 is flush with the bottom surface of the track 11. At this time, the push cylinder 12 pushes the slide plate 91 from the lifting platen 312 into the track 11 from the front end of the track 11. Under the mutual push of the slide plates 91, all the slide plates 91 in the track 11 move forward one station. At this time, the last slide plate 91 in the track 11 is located above the second opening 112 after moving. Before the slide plate 91 moves to the second opening 112, the second opening 112 has been filled with the lifting platen 312 of the second lifting assembly 32, that is, the last slide plate 91 is also on the lifting platen 312 of the second lifting assembly 32. After the unloading device removes the piston 92 and valve plate 93 that have been sorted on the slide plate 91, the lifting platen 312 of the second lifting assembly 32 rises with the slide plate 91 and transfers to the conveyor belt 211.

[0050] In this embodiment, during the process of removing the sorted piston 92 and valve plate 93 on the slide plate 91 located above the second opening 112, if the slide plate 91 is not fixed, the piston 92 and valve plate 93 may sometimes get stuck on the discharge rod 912, thereby lifting the slide plate 91 together.

[0051] In order to prevent this situation from happening, a tail baffle 13 and a blocking slider 14 are further provided at the rear end of the track 11, and the blocking slider 14 is connected to the second cylinder 15; the tail baffle 13 is provided with a first inclined surface 131 on the surface of the side facing the track 11, and the blocking slider 14 is provided with a second inclined surface 141 that slides with the first inclined surface 131. The blocking slider 14 is located in the track 11, and the second cylinder 15 is used to drive the blocking slider 14 to move along a length direction different from the track 11.

[0052] When the piston 92 and the valve plate 93 are removed, the second cylinder 15 is used to drive the blocking slider 14 to move into the track 11. The blocking slider 14 squeezes the side of the slide plate 91 to fix the slide plate. After the piston 92 and the valve plate 93 are removed, the second cylinder 15 drives the blocking slider 14 to return to its original position to release the fixation.

[0053] The slide plate rotary conveying device in this embodiment is mainly used in the valve plate sorting machine for automatic assembly of shock absorbers, and is used to realize the conveyance of the slide plate 91, so that the slide plate 91 passes through each station, and the device at each station works to realize the sorting of the valve plate 93. The track 11, the side baffle 212 of the conveying line 21, the push cylinder 12 and the second cylinder 15 are all installed on the platform plate 41 of the equipment.

[0054] The embodiments of the present application have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments. The selection of terms used herein is intended to best explain the principles of the embodiments, practical applications, or improvements to the technology in the market, or to enable other persons of ordinary skill in the art to understand the embodiments disclosed herein.
