The lifting mechanism 11 can orderly feed a plurality of bodies a to the distributing mechanism 12 through the transmission line 14 from bottom to top and in a roughly inclined manner, and the distributing mechanism 12 is provided with a plurality of clamping assemblies 121 for individually clamping each body a and moving to the carrying mechanism 13 so that the carrying mechanism 13 can deliver each body a to the next process in a hoisting manner.

The placing unit 2 at least comprises a rotating station, a pre-assembling station, a lock cylinder station and an acceptance station, the rotating station is formed by a rotating disc 21, a jig mechanism 22 capable of forming the pre-assembling station is configured on the rotating disc 21, and the jig mechanism 22 comprises a limiting component 221 and a bearing component 222, wherein the limiting component 221 is used for bearing a body A hoisted by the carrying mechanism 13 in a vertically inserting mode, and the bearing component 222 is matched with the limiting component 221 and is provided with a valve core B. The body a of the position limiting component 221 can be aligned with the valve core B of the supporting component 222 to complete the predetermined assembly, and when the rotating station rotates to be aligned with the lock cylinder station, the body a and the valve core B in the jig mechanism 22 are driven to lock and nest the valve core B at the bottom of the body a in a pressing assembly manner. And the semi-finished product assembled at the lock core station can be subjected to further checking and inspection at an acceptance station.

The transfer unit 4 is used for temporarily storing the semi-finished products transferred in the previous process. And the second feeding mechanism 32 can automatically convey the rubber rings C to the pressing area of the pressing mechanism 43 in a uniform state according to the preset assembling requirement.

The transfer unit 4 at least has a placing mechanism 41, and a limiting mechanism 42 and a pressing mechanism 43, which are configured on the placing mechanism 41 and used for forming an assembling station, and the limiting mechanism 42 is matched with the limiting mechanism 42 to press the rubber ring C into the top of the body a of the semi-finished product, the semi-finished product can be inserted and fixed at the assembling station in an upright state, and when the placing mechanism 41 moves the limiting mechanism 42 to be opposite to the pressing mechanism 43, the pressing mechanism 43 equipped with the rubber ring C is driven to mount the rubber ring C to the top of the body a in a press-fit and nesting manner, so as to assemble the finished product of the valve.

The blanking unit 5 is disposed on the downstream side of the production line, and can convey and transfer the finished products in the transfer unit 4 to an external sorting area by lifting.

Through the description of the above embodiment, it is obvious that, compared with the prior art, in this embodiment, the parts of the valve, such as the body a, the valve core B, and the rubber ring C, are sequentially assembled through the assembly line in an automated manner, the body a with the valve core B assembled thereon is assembled into a semi-finished product, and then the rubber ring C is assembled on the semi-finished product, so that the finished product of the valve is assembled, and the assembly requirement of the automatic and efficient production line is met.

What is more important is that, on the one hand, the first feeding unit 1 automatically and efficiently transports the body a of the valve to the placing unit 2 through the lifting mechanism 11, the material distributing mechanism 12 and the carrying mechanism 13 which are configured in sequence to prepare for the next process, and the second feeding unit 3 automatically transports other parts (the valve core B and the rubber ring C) which need to be assembled to the region which needs to be assembled respectively in a uniform state according to the preset assembling requirements through the two feeding mechanisms, so that the different parts are automatically separated without manual sorting, the assembling efficiency is greatly improved, and the work burden and the production cost of personnel are reduced. On the other hand, the body A and the valve core B are cooperatively operated through all stations of the placing unit 2, the assembly and checking acceptance of semi-finished products are achieved, the semi-finished products and the rubber ring C can be just nested in a pressing mode under the cooperation of the limiting mechanism 42 and the pressing mechanism 43 in the transfer unit 4, the finished product of the valve is assembled, the short plate is greatly prevented from being manually operated, defective products and waste products caused by neglected loading are reduced, and the production efficiency and the productivity are greatly improved.

Referring to fig. 2, 3 and 4, in one embodiment, the body a is preferably substantially in the shape of a T-shaped rod. Wherein, hoist mechanism 11 includes: a machine bed 111, a feed track 112 and a drive (not shown). Specifically, the machine 111 has a workpiece storage bin 113 for accommodating the main body a. The feeding crawler 112 is obliquely disposed on the machine base 111, the feeding crawler 112 is formed with a plurality of regularly transverse engaging cavities 114, and the engaging cavities 114 are configured to enable the body a in the storage bin 113 to be laterally engaged and transferred to the conveying line 14. The driving member is linked with the feeding track 112 to drive the feeding track 112 to continuously convey the body a in the direction of the conveying line 14. Therefore, the feeding crawler 112 continuously and efficiently feeds the workpieces stacked in the storage bin 113 to the conveying line 14 through the T-shaped body a and the engaging cavity 114 provided in a shape similar to the body a.

Furthermore, the feeding crawler 112 is disposed in the storage bin 113 in an inclined manner in a conveyor manner and can drive the main body a disposed in the engaging cavity 114 to move from bottom to top to a high position close to the conveying line 14, and the main body a in the engaging cavity 114 is separated from the conveying line 14 by the feeding crawler 112 and continuously moves to enter the conveying line 14 in a predetermined manner. An obtuse angle structure which is inclined to the storage bin 113 and outwards slantwise forms conveying force beneficial to the body A by self gravity and the crawler belt, the crawler belt forms an annular conveying belt mode under the driving of a driving piece, the body A located at a low position is conveyed to a high position through the clamping cavity 114, and when the feeding crawler belt 112 is continuously conveyed to one side closer to the conveying line 14, under the action of the opening of the clamping cavity 114 and the self gravity of the body A, the body A in the clamping cavity 114 can be separated when conveyed to the back (as in another conveying surface of the feeding crawler belt 112 in fig. 4) and enters the conveying line 14 in a preset posture, so that the purpose of conveying from bottom to top is achieved.

Further, wherein the transmission line 14 is configured to: the slide groove is formed by two guide rails 141 arranged at intervals, and the distance between the slide groove and the guide rail is smaller than the top of the T-shaped body a and larger than the bottom of the T-shaped body a, so that the bodies a departing from the feeding crawler 112 can be sequentially arranged in a hanging manner and can be slidably transferred to the clamping assembly 121. The transmission line 14 is configured to facilitate the top of the T-shaped body a to be clamped in the sliding groove and to be capable of freely sliding from top to bottom, so that the bodies a transported by the feeding crawler 112 are sequentially and slidably conveyed in a hanging manner. So that each workpiece can be sequentially fed into the gripper assembly 121 located at the feed mechanism 12. Specifically, the plurality of gripping assemblies 121 wait in sequence at the exit of the conveying line 14, individually grip one conveyed body a, and transfer the body a to the conveying mechanism 13. It is understood that the gripping assembly 121 may be a pneumatic claw configured to be opened and closed by engaging with the head of the body a, and may allow the lifting structure of the carrying mechanism 13 to be directly engaged with the top of the body a on the pneumatic claw to lift and transfer the body a to the next process (the pneumatic claw does not vertically limit the body a). Furthermore, the gripping assembly 121 may be disposed on different sliding seats, and sequentially and independently conveyed between the conveying mechanism 13 and the outlet of the conveying line 14, or the reciprocating conveyance of the gripping assembly 121 may be realized by sliding and avoiding, which is not limited herein.

The above may be a state where the body a is directly dropped into the entrance of the transmission line 14, and then the bottom is adapted downward, and the top is slidably engaged between the two rails 141. In another embodiment, an adjusting set (not shown) for adjusting the entering posture of the body a is added at the joint where the body a enters the production line, and the adjusting set can be in the form of an arc baffle plate to further finely adjust the body a to enter the transmission line 14, and still slide into the transmission line 14 smoothly through the self gravity of the body a (because the head and the foot of the T-shaped body a are light).

In other words, even if an emergency occurs, the body a may not slide into the transmission line 14 in a hanging manner, and the body a may be effectively blocked by the roller brush 15. Specifically, as the body a is easy to have sundries or other objects at the T-shaped head position during stacking or transportation, which may cause the subsequent sleeved rubber ring C to be obstructed, particularly, a roller brush 15 is disposed above the transportation line 14, and a cleaning surface of the roller brush 15 can at least abut against the top of the body a sliding along the transportation line 14 to the material distribution mechanism 12, and the roller brush 15 is driven by the sliding body a to rotate. The roller brush 15 is located at the middle part of the transmission line 14 and can intercept the body a sliding transversely along the end surface of the transmission line 14. Therefore, the head of the body A is cleaned through the rotatable roller brush 15 arranged above the transmission line 14, the roller brush 15 can rotate under the sliding triggering of the bodies A without being driven by a power source, the design is ingenious, the roller brush 15 is directly transversely arranged on the transmission line 14 and approximately transversely cuts the transmission line 14 in the middle section, the body A sliding in other modes (for example, the body A is directly transversely arranged and slides on the end face between two rails) can be blocked, the body A which is not beneficial to clamping the clamping assembly 121 is screened, and the normal operation of the production line is ensured.

In one embodiment, the machine 111 is separately disposed at an interval at the upstream side of the production line and is connected to the lifting mechanism 11 and the material distributing mechanism 12 through the transmission line 14, only the lifting mechanism 11 is located on the machine 111, and the rest mechanisms are located on the other machine. The lifting mechanism 11 of the first feeding unit 1 can be separated from other units and mechanisms independently in the configuration mode, the feeding source is separated, only the transmission line 14 is reserved to be connected with the next process, and the situations of interference, misoperation and the like are greatly avoided.

Referring to fig. 5 and 6, the lock cylinder station includes a stamping mechanism 23 disposed above the rotary disc 21, the stamping mechanism 23 has a pressing head 231 disposed in a shape similar to the top of the body a, and the pressing head 231 can be pressed onto the top of the body a movably sleeved on the limiting component 221 in a vertical lifting manner, so as to assemble the valve core B located at the bottom into the body a under the support of the supporting component 222. The pressing head 231 may be a gantry type lifting pressing type, so as to press and assemble the body a and the valve core B, which are disposed at the preassembly station in a facing manner. It should be mentioned that the precise rotation and operation of the rotary disk 21 at the various stations can be further achieved by displacement sensors. The jig mechanism 22 and the punching mechanism 23 in this embodiment are suitable for assembly between the press-fitting type body a and the valve core B in the valve structure.

In other embodiments, threads or other types of assembly between the valve core B and the body a may be provided by configuring the key cylinder station as a means to facilitate a rotational locking, and therefore will not be described.

With reference to fig. 7 and 8, the checking station has a checking means 24 for checking the ventilation of the semifinished product. The inspection mechanism 24 includes: a stopper 241, a thimble assembly 242 and an inflation assembly 243. The stopping table 241 can be placed and fastened to the semi-finished product in a vertically fixed manner and can expose at least the top and the bottom of the semi-finished product. The needle assembly 242 is disposed below the stopper 241 and is engageable with a valve core B fixed to a bottom portion of a blank on the stopper 241 to release the valve core B from closing the outlet side of the air passage. The inflation assembly 243 is slidably disposed above the stopper 241, and is switchable between a first position where it is in contact with the inside of the stopper to communicate with the inlet of the air passage at the top of the semi-finished product for ventilation and a second position where it is slid away from the semi-finished product to close the ventilation.

The fastening manner for the stopper 241 may be direct transverse clamping and limiting, or an installation cavity (not shown) capable of supporting a semi-finished product is formed, and at least the ejector pin assembly 242 at the bottom is allowed to enter into the clamped valve core B, and the top is exposed outside the installation cavity. The inflation assembly 243 may be sealed with the air passage of the valve through an air supply passage to provide air to detect whether the body a with the valve core B is normally deflated. In addition, the inspection and determination after the inflation operation can be realized by disposing an air pressure sensing device associated with the air path on the inflation assembly 243 or disposing an air outlet detection device on the ejector pin assembly 242.

Referring to fig. 1, 9, 10 and 11, in one embodiment, the automatic valve assembly line further includes a transfer unit 6 and an air tightness detecting unit 7 disposed between the placing unit 2 and the transferring unit 4 in the conveying direction.

Wherein, the transfer unit 6 comprises a robot 61 and a manipulator 62 arranged on the robot 61 for lifting and clamping the semi-finished product, and the manipulator 62 is configured to be capable of clamping the T-shaped head of the semi-finished product, so that the tail of the semi-finished product moves vertically downwards. It should be noted that, in the production line, the conveying and transferring of the semi-finished product and the finished product containing the body a are the doubtful matters, and the lifting and clamping manner of the manipulator 62 is usually adopted. In order to be more convenient for hoist and mount being T type pole form, adopt the jack catch that sets up with T type head profile modeling to realize the clamping, and hoist and mount and remove to required station department, do benefit to the vertical placing of body A to unified centre gripping, placing mode make more normal, reasonable operation cooperation between each unit of production line.

The air tightness detecting unit 7 has a detecting plate 71 for receiving the semi-finished product transferred by the transferring unit 6 and a detector 72 cooperating with the detecting plate 71. The semi-finished product is accommodated on the detection disc 71, and the tail part of the semi-finished product can be clamped and fixed with a profiling cavity formed in the detection disc 71. The detector 72 is in communication with the head of the blank to vent into the air passage channel so that the detector 72 can derive the hermetic properties of the blank. The inspection means 24 can detect defective products of the semi-finished products, but this detection method cannot screen defective products of the leaked gas. Therefore, the detector 72 of the air tightness detecting unit 7 simulates the inflation of the inlet side of the air passage of the semi-finished product, and the air core B is not plugged by the side of the detecting plate 71, so that whether the air leakage occurs in the valve of the whole semi-finished product can be determined by inflation, and the air tightness performance can be sequentially determined.

In the present embodiment, the detection plate 71 may be configured to be equipped with an air leakage sensor to correspondingly detect whether the air leakage phenomenon exists in the valve core B. In addition, the detector 72 should be provided with a gas supply unit, and a change rate monitoring unit for sensing an increase/decrease amount per unit time after the gas is introduced into the gas passage, so as to perform the airtightness detection in multiple directions.

In general, the two feeding mechanisms are preferably of a vibrating plate structure and are respectively arranged in an alignment area and a pressing area which are required to be supplied to the corresponding materials. Specifically, a pulse electromagnet is arranged below the vibrating disc hopper, so that the hopper can vibrate in the vertical direction, and the hopper is driven to do torsional vibration around the vertical axis of the hopper. The material in the hopper (valve core B or rubber ring C) rises along the spiral track due to the vibration. During the ascending process, the parts can automatically enter the assembling or machining position in a uniform state according to the assembling or machining requirements through screening or posture change of a series of tracks. The working purpose is to automatically, orderly, directionally and neatly arrange the disordered workpieces by vibration and accurately convey the disordered workpieces to the next procedure. Therefore, the valve core B and the rubber ring C for assembling on the body a can be arranged in the alignment area of the supporting component 222 of the jig mechanism 22 and the pressing area of the pressing mechanism 43 according to the preset assembling requirement. The precise allocation of the valve core B in the alignment area and the rubber ring C in the pressing area can be achieved by a series of automatic conveying lines, or can be achieved directly by the driving of the central control system by the robot 61, which is not described in the present application.

Referring to fig. 12 and 13, the specific configuration of the pressing mechanism 43 can refer to the structural schematic of the punching mechanism 23. The lower end face of the pressing portion 431 in the pressing mechanism 43 is configured with a pressing area, and the rubber ring C conveyed by the feeding mechanism can be clamped in the pressing area according to a preset assembly requirement, so that the rubber ring C is driven to be nested and assembled with the top of the semi-finished product body a on the limiting mechanism 42 when the pressing mechanism 43 works.

It is to be noted, among others, that in the above description, the upstream side and the downstream side of the production line are defined based on the conveying direction of the body a, the semi-finished products, and the finished products.
