Description

Technical Field

[0001] The present invention relates to machinery for assembling a variety of different components into a combined unit, and more particularly to an automated device for valve train assembly with the ability to accurately detect valve plates. Background Art

[0002] In the assembly process of the return valve and the bottom valve, basically, the relevant parts of the valve train are first sleeved onto the rod in sequence to form a pre-assembled part, and then the pre-assembled part is fastened as required. Automated assembly is an effective means to improve production efficiency. In recent years, automated equipment manufacturers have been committed to developing automated equipment capable of realizing valve train assembly.

[0003] During the valve train assembly process, it is necessary to avoid missing or having multiple valve plates. Existing automated equipment for valve train assembly basically detects the overall thickness of the pre-assembled part. If the thickness is within the set range, it is determined to be qualified, and it is considered that there is no problem of missing or having multiple valve plates. However, due to the fact that the dimensional tolerance of the valve body made by powder metallurgy die casting currently cannot reach the required level, when the valve plate and the valve body are assembled together for detection, the results are unstable, there are many misjudgments. Once defective products flow to the next work station, it will cause product defects that require rework or even scrapping, thus resulting in waste of labor costs and material costs. In addition, the tooth groove size and quantity of the throttle valve plate will affect the performance of the valve. The thickness of the throttle valve plate is only 0.1 mm - 0.2 mm, and its color is the same as that of the ordinary valve plate. It is difficult to detect when the throttle valve plate and the ordinary valve plate are assembled together. After retrieval, no valve train automated assembly equipment with the ability to detect the throttle valve plate has been found.

[0004] In addition, in the prior art, the valve body feeding adopts a belt conveyor line (such as the bottom valve feeding mechanism adopted in Chinese Patent Document CN 212286620 U), which is prone to material jamming, requires personnel intervention, causes waste of personnel, increases costs, and occupies a large space, wasting factory floor space. Summary of the Invention

[0005] In order to overcome the deficiencies in the prior art, the present invention provides an automated device for valve train assembly with the ability to accurately detect valve plates. This automated device can detect the throttle valve plate to ensure accurate tooth groove size and quantity, and can accurately detect the thickness of the valve plate, effectively avoiding the influence of valve body dimensional errors. In addition, the automated device for valve train assembly with the ability to accurately detect valve plates according to the present invention is provided with a specific valve body feeding module at the valve body feeding station, which has high reliability, effectively reduces labor costs, and occupies a small space.

[0006] The technical solution of the present invention is as follows:

[0007] An automated device for valve train assembly with precise valve disc detection ability, including a carrier circulation track module; the carrier circulation track module includes a circulation track, and carriers that can move in a cycle are arranged on the circulation track; positioning rods are provided on the carriers; along the circulation track, feeding stations for relevant valve train parts are arranged according to the assembly sequence; the feeding stations include at least one multi-piece feeding station for realizing the feeding of throttle valve discs and a valve body feeding station; the multi-piece feeding station for realizing the feeding of throttle valve discs is provided with a valve disc feeding module and a valve disc receiving and detecting module; the valve disc receiving and detecting module includes a pair of first-level receiving plates arranged above the circulation track, and the distance between the two first-level receiving plates enables the positioning rod to pass through; a pair of second-level receiving plates are arranged above the first-level receiving plates, and the distance between the two second-level receiving plates enables the positioning rod to pass through; the valve disc feeding module includes a corresponding magnetic separation device and a valve disc suction device, the magnetic separation device has a group of piercing rods arranged in groups, correspondingly, the valve disc suction device has a group of negative pressure suction heads arranged in groups, and the valve disc suction device is used to suck the valve discs from the magnetic separation device and then sleeve the valve discs onto the positioning rods of the carriers; after the valve discs are sleeved onto the positioning rods, the throttle valve discs fall onto the second-level receiving plates, and the ordinary valve discs fall onto the first-level receiving plates; a throttle valve disc CCD detection device is arranged above the end of the second-level receiving plate, and after the throttle valve discs are detected by the CCD, they fall onto the first-level receiving plates; a valve disc thickness detection device is arranged above the end of the first-level receiving plate.

[0008] Compared with the prior art, in the above-mentioned automated device for valve train assembly of the present invention, by setting a valve disc receiving and detecting module at the multi-piece feeding station for realizing the feeding of throttle valve discs, during operation, after the valve discs are sleeved onto the positioning rods of the carriers, they will not directly fall onto the carriers. Among them, the throttle valve discs will first fall onto the second-level receiving plates, and the ordinary valve discs will first fall onto the first-level receiving plates. After the throttle valve discs are detected by the CCD at the end of the second-level receiving plates, they then fall onto the first-level receiving plates and are stacked together with the ordinary valve discs. Finally, thickness detection is carried out at the end of the first-level receiving plates, and then they fall onto the carriers as a whole, realizing precise detection of the tooth groove size, quantity of the throttle valve discs, and the total thickness of the valve discs, effectively avoiding the situation that the tooth groove size and quantity of the throttle valve discs do not meet the requirements, or there are missing or extra valve discs, thereby effectively preventing defective products from flowing to the next station, resulting in product defects that require rework or scrapping, and further avoiding waste of labor costs and material costs.

[0009] As an optimized solution, in the above-mentioned automated device for valve train assembly with precise valve disc detection ability, in order to reduce the reflection of the valve discs, the light source color of the throttle valve disc CCD detection device is blue, and the end of the second-level receiving plate is blackened.

[0010] In a specific implementation case, the aforementioned automated equipment for valve system assembly with precise valve disc detection ability is used to assemble the rebound valve of a shock absorber. It has two multi-piece feeding stations for feeding throttle valve discs, namely the upper valve disc multi-piece feeding station and the lower valve disc multi-piece feeding station. Further, along the circulating track, there are arranged a lower limit piece feeding station, a lower valve disc multi-piece feeding station, a lower thick piece feeding station, a lower thin piece feeding station, a valve body feeding station, an upper thin piece feeding station, an upper thick piece feeding station, an upper valve disc multi-piece feeding station, and an upper limit piece feeding station.

[0011] As an optimized solution, in the aforementioned automated equipment for valve system assembly with precise valve disc detection ability, a valve body feeding module is provided at the valve body feeding station; the valve body feeding module includes a correspondingly arranged valve body feeding turntable device, a valve body lifting manipulator, and a valve body feeding manipulator; the valve body feeding turntable device includes an indexing plate and a set of material-passing rods arranged on the indexing plate; during operation, the valve body feeding manipulator grabs the valve body from the material-passing rod located below it, and then sleeves the valve body on the positioning rod of the carrier; every time the valve body feeding manipulator grabs a valve body from the material-passing rod, the valve body lifting manipulator lifts the remaining valve bodies on this material-passing rod by a height equivalent to the thickness of one valve body; when all the valve bodies on the material-passing rod have been grabbed, the indexing plate rotates to turn the next material-passing rod sleeved with a valve body to the lower part of the valve body feeding manipulator. With the above design, the valve body feeding turntable device, the valve body lifting manipulator, and the valve body feeding manipulator work together to achieve automatic valve body feeding, with high reliability and no need for manual intervention. Workers only need to replenish materials in time when the material-passing rod is out of stock, which can reduce labor costs. Moreover, the valve body feeding module has the advantage of occupying less space compared with a conventional belt conveyor line.

[0012] Further, in the aforementioned automated equipment for valve system assembly with precise valve disc detection ability, a bottom support is provided at the lower end of the material-passing rod, and the bottom support is detachably connected to the indexing plate. Thus, workers only need to remove the out-of-stock material-passing rod and then replace it with a material-passing rod that has been pre-sleeved with a valve body to complete the material replenishment, which has the advantage of being easy to operate.

[0013] Further, in the aforementioned automated equipment for valve system assembly with precise valve disc detection ability, the valve body lifting manipulator includes a lifting device, a telescopic device, and a lifting arm; during operation, the telescopic device drives the lifting arm to extend, the lifting arm holds the valve body, and the lifting device lifts the valve body through the lifting arm; when the indexing plate needs to rotate, the telescopic device drives the lifting arm to retract. With this design, the valve body lifting manipulator has high reliability and is easy to implement.

[0014] Further, in the aforementioned automated equipment for valve train assembly with the ability to accurately detect valve plates, the valve body loading station further has a valve body positive / negative detection module; the valve body positive / negative detection module includes a valve body CCD detection device and a valve body turning manipulator; the valve body CCD detection device is used to perform positive / negative detection on the valve body sleeved on the positioning rod; when the valve body turning manipulator detects that the valve body is facing the wrong direction, it grabs the valve body, turns it over and then sleeves it back onto the positioning rod. Thus, during valve train assembly, the valve body CCD detection device performs positive / negative detection on the valve body sleeved on the carrier positioning rod, and the valve body turning manipulator corrects the valve body facing the wrong direction, further improving the reliability of the equipment.

[0015] As an optimized solution, in the aforementioned automated equipment for valve train assembly with the ability to accurately detect valve plates, the upper limit piece loading station is the same as the lower limit piece loading station; the lower limit piece loading station is provided with a limit piece loading module and a limit piece receiving and detecting module; the limit piece receiving and detecting module includes a pair of limit piece receiving plates arranged above the circulating track, and the gap between the two limit piece receiving plates enables the positioning rod to pass through; a limit piece thickness detection device is arranged above the end of the limit piece receiving plate; the limit piece loading module is used to grab the limit piece and sleeve it onto the positioning rod. During operation, after the limit piece is sleeved onto the positioning rod, it falls onto the limit piece receiving plate, and when it moves to the end of the limit piece receiving plate, the limit piece thickness detection device performs thickness detection on the limit piece. By setting the limit piece receiving and detecting module at the limit piece loading station, the thickness of the limit piece can be detected, and the setting of the limit piece receiving plate improves the accuracy of detection, effectively avoiding the situation of missing or overloading the limit piece, thereby further improving the reliability of the equipment.

[0016] As an optimized solution, in the aforementioned automated equipment for valve train assembly with the ability to accurately detect valve plates, the upper thick piece loading station is the same as the lower thick piece loading station; the lower thick piece loading station is provided with a thick piece loading module and a thick piece receiving and detecting module; the thick piece receiving and detecting module includes a pair of thick piece receiving plates arranged above the circulating track, and a thick piece CCD detection device and a thick piece turning manipulator arranged above the thick piece receiving plates in sequence; the thick piece loading module is used to grab the thick piece and sleeve it onto the positioning rod. During operation, after the thick piece is sleeved onto the positioning rod, it falls onto the thick piece receiving plate, and when it moves below the thick piece CCD detection device with the carrier, the thick piece CCD detection device performs detection on the thick piece. If it detects that the thick piece is facing the wrong direction, when the thick piece moves below the thick piece turning manipulator, the thick piece turning manipulator grabs the thick piece, turns it over and then sleeves it back onto the positioning rod. Thus, at the thick piece loading station, the thick piece can be detected and corrected when facing the wrong direction, avoiding the problem of reverse installation of the thick piece, thereby further improving the reliability of the equipment. Moreover, when preparing the thick piece, there is no requirement for the orientation of the thick piece, which helps to reduce the burden on workers and improve efficiency.

[0017] Furthermore, as an optimized solution, in the aforementioned automated equipment for valve train assembly with the ability to precisely detect valve plates, the upper thin plate loading station is the same as the lower thin plate loading station; the lower thin plate loading station is provided with a thin plate loading module and a thin plate receiving and detecting module; the thin plate receiving and detecting module includes a pair of thin plate receiving plates disposed above the circulating track, and the gap between the two thin plate receiving plates enables the positioning rod to pass through; a thin plate thickness detecting device is provided above the end of the thin plate receiving plate; the thin plate loading module is used to grab the thin plate and sleave it onto the positioning rod. During operation, after the thin plate is sleaved onto the positioning rod, it falls onto the thin plate receiving plate, and when it moves to the end of the thin plate receiving plate, the thin plate thickness detecting device detects the thickness of the thin plate. Thus, during operation, the thin plate first falls onto the thin plate receiving plate, and after being thickness-detected at the end of the thin plate receiving plate, it then falls onto the carrier and is stacked with the valve train parts that have been assembled in the previous process, thereby enabling precise detection of the thin plate and further improving the reliability of the equipment.
