Technical Field

[0001] The invention relates to the technical field of valve assembly, and in particular to a valve assembly device. Background Art

[0002] Valves are widely used in various fields, such as the on-off valve in the shower, which commonly includes a valve body, a valve stem, a moving valve plate, a static valve plate and a rubber pad at the tail end. This type of on-off valve is generally assembled manually with the assistance of partial expansion and pressing devices, with a low degree of automation and low efficiency, and needs to be improved. Summary of the invention

[0003] To solve at least one of the above technical defects, the present invention provides the following technical solutions:

[0004] The present application document discloses a valve assembly device, including a valve stem assembly mechanism, a valve body assembly mechanism, and an air tightness detection mechanism, wherein the valve stem assembly mechanism and the valve body assembly mechanism are connected by a first transfer mechanism, and the valve body assembly mechanism and the air tightness detection mechanism are connected by a second transfer mechanism;

[0005] The valve stem assembly mechanism comprises a first turntable mechanism, a first valve stem feeding mechanism, a first O-ring feeding mechanism, and a first unloading mechanism. The first valve stem feeding mechanism, the first O-ring feeding mechanism, and the first unloading mechanism are arranged around the first turntable mechanism. After the first turntable mechanism moves to a predetermined position, the first valve stem feeding mechanism and the first O-ring feeding mechanism are used to feed materials to the first turntable mechanism, and the first unloading mechanism moves the materials on the first turntable mechanism to the first transfer mechanism.

[0006] The valve body assembly mechanism comprises a second turntable mechanism, a second valve stem feeding mechanism, a valve body feeding mechanism, a static valve piece feeding mechanism, a dynamic valve piece feeding mechanism, a second O-ring feeding mechanism, and a second unloading mechanism. The second valve stem feeding mechanism, the valve body feeding mechanism, the static valve piece feeding mechanism, the dynamic valve piece feeding mechanism, the second O-ring feeding mechanism, and the second unloading mechanism are arranged around the second turntable mechanism. After the second turntable mechanism moves to a predetermined position, the second valve stem feeding mechanism moves the material at the first transfer mechanism to the second turntable mechanism, the valve body feeding mechanism, the static valve piece feeding mechanism, the dynamic valve piece feeding mechanism, and the second O-ring feeding mechanism feed the material to the second turntable mechanism, and the second unloading mechanism moves the material on the second turntable mechanism to the second transfer mechanism.

[0007] The air tightness detection mechanism includes a third turntable mechanism, a clamping and feeding mechanism, a rubber pad feeding mechanism, and an air tightness detection component. The clamping and feeding mechanism, the rubber pad feeding mechanism, and the air tightness detection component are arranged around the third turntable mechanism. After the third turntable mechanism moves to a predetermined position, the clamping and feeding mechanism moves the material at the second transfer mechanism to the third turntable mechanism, the rubber pad feeding mechanism feeds the material to the third turntable mechanism, and the air tightness detection component performs an air tightness detection on the material on the third turntable mechanism.

[0008] It also includes a clamping mechanism, wherein a clamping mechanism is provided between the valve body feeding mechanism and the second valve stem feeding mechanism and between the rubber pad feeding mechanism and the air tightness detection assembly, so that the clamping mechanism performs a clamping action on the material passing from below;

[0009] It also includes a feeding pipe, a feeding push-up mechanism and a blowing mechanism arranged adjacent to the feeding pipe. The feeding push-up mechanism is located below the turntable in the third turntable mechanism and an ejection hole is arranged at a corresponding position of the turntable. After the feeding push-up mechanism ejects the material, the blowing mechanism is used to blow the material into the feeding pipe cavity.

[0010] In this scheme, the valve stem assembly mechanism, the valve body assembly mechanism and the air tightness detection mechanism are designed to complete the assembly and molding of the valve, which helps to improve the degree of automation and improve the assembly efficiency.

[0011] Specifically, in the valve stem assembly mechanism, the first turntable mechanism is rotated to move the material to different workstations, and the first valve stem loading mechanism, the first O-ring loading mechanism, and the first unloading mechanism perform corresponding actions. For example, the first valve stem loading mechanism moves the corresponding valve stem part to the fixture in the first turntable mechanism. As the turntable rotates, the first O-ring loading mechanism installs the O-ring on the valve stem. The number of first O-rings can be increased accordingly according to demand. The turntable moves the valve stem component after the O-ring is assembled to the first unloading mechanism, and the first unloading mechanism moves the valve stem to the first transfer mechanism, which is then moved to the valve body assembly mechanism by the first transfer mechanism.

[0012] Afterwards, the second valve stem feeding mechanism at the valve body assembly mechanism moves the valve stem to the fixture in the second turntable mechanism, and moves it to the corresponding workstation through the turntable. When in use, the valve body is moved to the fixture in the second turntable mechanism through the valve body feeding mechanism, and the turntable moves the valve body to the workstation where the second valve stem feeding mechanism is located. The second valve stem feeding mechanism moves the valve stem at the first transfer mechanism to the valve body for assembly, and then moves with the turntable to the movable valve plate feeding mechanism, the static valve plate feeding mechanism, and the second O-ring feeding mechanism workstation to complete the installation of the movable valve plate, the static valve plate, and the O-ring respectively. Then, the assembled valve body is moved to the second unloading mechanism to feed it to the second transfer mechanism, and the second transfer mechanism moves the assembled valve body to the air tightness detection mechanism.

[0013] The valve body at the second transfer mechanism is moved to the fixture in the third turntable mechanism by a clamping loading mechanism, and then moved to the rubber pad loading mechanism along with the turntable to complete the installation of the rubber pad on the valve body. The air tightness of the valve is then tested by an air tightness detection component, and the material can be unloaded manually or by other mechanisms for unloading.

[0014] The position of the corresponding parts can be adjusted twice through the clamping mechanism, which is convenient for subsequent operations and helps to improve stability and yield rate. After the ejecting mechanism ejects the material, the blower mechanism blows the material into the unloading tube cavity, which is convenient for unloading and helps to improve the degree of automation.

[0015] Furthermore, the first valve stem feeding mechanism, the second valve stem feeding mechanism, and the clamping feeding mechanism all include a horizontal shifting mechanism, a lifting mechanism, and a clamping mechanism. A lifting mechanism is arranged at the moving end of the horizontal shifting mechanism, and a clamping mechanism is arranged at the moving end of the lifting mechanism. After the horizontal shifting mechanism moves the clamping mechanism to a predetermined position, the lifting mechanism is used to adjust the longitudinal position of the clamping mechanism to clamp or release the material. The horizontal shifting mechanism is such as a cylinder or a screw shifting mechanism, the lifting mechanism is such as a cylinder or a screw shifting mechanism, etc., and the clamping mechanism is such as a common cylinder clamp, which has a simple structure and low cost.

When in use, the position of the support ring mechanism one is adjusted by cooperating with the horizontal shift mechanism two and the lifting mechanism two so that the O-ring is sleeved on the end of the clamping block. When installed on the valve body, the clamping block is squeezed open by the valve body to support the O-ring so that it slides off at the predetermined position of the valve body, and then the support ring mechanism one moves up and separates from the valve body, and the clamping block is reset under the action of the elastic member. The structure is simple and easy to operate.

The vibration disk feeding helps to further improve the degree of automation. The base 1 integrates various functional mechanisms to facilitate transportation and factory placement.

[0019] Furthermore, the valve body feeding mechanism includes a horizontal shift mechanism four, a lifting mechanism five, and a clamping mechanism four. The lifting mechanism five is arranged at the moving end of the horizontal shift mechanism four, and the clamping mechanism four is arranged at the moving end of the lifting mechanism five. The position of the clamping mechanism four is adjusted by cooperating with the horizontal shift mechanism four and the lifting mechanism five to complete the clamping of materials and feeding to the turntable. The structure is simplified and the layout and operation are convenient.

[0020] Furthermore, the movable valve plate feeding mechanism includes a horizontal shift mechanism five, a lifting mechanism six and an adsorption mechanism one. The lifting mechanism six is ​​arranged at the moving end of the horizontal shift mechanism five and the adsorption mechanism one is arranged at the moving end of the lifting mechanism six. The horizontal shift mechanism five cooperates with the lifting mechanism six to move the position of the adsorption mechanism one, so that the adsorption mechanism one absorbs the material or places the material at the required position of the second turntable mechanism. The position of the adsorption mechanism one is adjusted by cooperating with the horizontal shift mechanism five and the lifting mechanism six, so that the structure is simplified and the layout and operation are convenient.

[0021] Furthermore, the static valve plate feeding mechanism includes a horizontal shift mechanism six, a lifting mechanism seven and a clamping mechanism five.

After the second turntable mechanism moves to a predetermined position, the longitudinal telescopic mechanism and the transverse telescopic mechanism cooperate to adjust the corresponding position of the glue outlet in the glue discharge assembly and the material on the second turntable mechanism. The addition of the glue dispensing mechanism can drip a proper amount of glue after the movable valve plate is installed, so as to improve the stability of the connection between the movable and static valve plates through the glue, and at the same time do not hinder the relative rotation of the movable valve plate.

The support seat is provided with a horizontal reciprocating displacement mechanism and a receiving groove is arranged at a position corresponding to the discharge port on the support seat, and a groove is arranged on the slider. In the initial position, the groove corresponds to the receiving groove so that the material enters the groove. The horizontal reciprocating displacement mechanism moves the slider so that the groove and the receiving groove are misaligned for the second valve stem feeding mechanism to pick up the material. Adding the material dividing mechanism facilitates the picking up of the corresponding mechanism and improves the stability of operation.

[0025] Furthermore, a positioning mechanism 1 is arranged on the moving path of the clamping mechanism 1 in the second valve stem feeding mechanism, and the positioning mechanism 1 includes a rotating mechanism 2 and a clamping mechanism 7.

The state of the corresponding component can be adjusted by rotation through the seasoning mechanism, which facilitates subsequent operations and improves the stability of operation and the yield rate.

[0026] Furthermore, a second positioning mechanism is provided between the valve body feeding mechanism and the second valve stem feeding mechanism. The second positioning mechanism includes a driving motor, a plug column, and a telescopic cylinder.

[0067] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0068] Example 1

[0069] like Figure 1 As shown, the valve assembly device in this example includes a valve stem assembly mechanism 1, a valve body assembly mechanism 2, and an air tightness detection mechanism 3, wherein the valve stem assembly mechanism 1 and the valve body assembly mechanism 2 are connected by a first transfer mechanism 4, and the valve body assembly mechanism 2 and the air tightness detection mechanism 3 are connected by a second transfer mechanism 5. For the first transfer mechanism and the second transfer mechanism, such as a common chute, the inclination of the chute can be adjusted to complete the transfer of materials.

[0070] For the valve stem assembly mechanism, Figure 1 , Figure 2 As shown, a first turntable mechanism 13, a first valve stem loading mechanism 10, a first O-ring loading mechanism 11, and a first unloading mechanism 12 are installed on a box frame type base 100. The first turntable mechanism is like a common multi-station turntable machine, and a corresponding fixture is installed on the top surface of the turntable. The first valve stem loading mechanism 10, the first O-ring loading mechanism 11, and the first unloading mechanism 12 are installed around the turntable in the first turntable mechanism 13, and the materials are transported to the corresponding station through the turntable, and then the functional mechanism of the station performs the corresponding action.

[0071] Among them Figure 2 , Figure 5As shown, the first valve stem feeding mechanism 10 includes a horizontal shifting mechanism 102, a lifting mechanism 103, and a clamping mechanism 104. The horizontal shifting mechanism is like a common screw shifting type. A lifting mechanism 103 is arranged longitudinally at its moving end. The lifting mechanism is like a common telescopic cylinder. A cylinder claw-type clamping mechanism 104 is installed at the moving end of the lifting mechanism. When in use, the horizontal position of the clamping mechanism is adjusted by the horizontal shifting mechanism, and the longitudinal position of the clamping mechanism is adjusted by the lifting mechanism. For example, the first valve stem feeding mechanism is fed with material through the vibration disk feeding mechanism, and the valve stem at the discharge port of the vibration disk feeding mechanism is clamped by the clamping mechanism. Then, the position of the clamping mechanism is adjusted by the cooperation of the horizontal shifting mechanism and the lifting mechanism, so that the clamped valve stem is moved to the clamp of the turntable. The clamping mechanism releases the material and moves the valve stem to the next station through the turntable.

[0072] A material distribution mechanism 16 can be installed at the discharge port of the vibrating plate feeding mechanism 14, such as Figure 2 , Figure 8 As shown, the material distribution mechanism 16 includes a support seat 164, a horizontal reciprocating displacement mechanism 161, and a slider 162. The support seat 164 is fixed on the base 100, and the horizontal reciprocating displacement mechanism 161 is installed on the support seat 164, such as a telescopic cylinder. The movable end of the telescopic cylinder is connected to the slider and the slider 162 is slidably connected to the support seat 164. A groove 163 is formed at the side of the slider 162, and a receiving groove 165 is formed at the support seat 164 corresponding to the groove 163. The receiving groove corresponds to the discharge port of the vibration plate. In the initial position, the groove corresponds to the receiving groove. The valve stem discharged from the discharge port enters the receiving groove and then enters the groove. The horizontal reciprocating displacement mechanism moves the slider to make the groove and the receiving groove misaligned, and then the second valve stem feeding mechanism clamps the valve stem at the groove.

[0073] For the first O-ring feeding mechanism, as shown in the figure Figure 2 , Figure 6 , Figure 7As shown, the first O-ring feeding mechanism 11 includes a horizontal shift mechanism 2 110, a lifting mechanism 2 111, and a support ring mechanism 1 112. The horizontal shift mechanism 2 is of a screw type and a telescopic cylinder type lifting mechanism 2 is installed at its moving end. The support ring mechanism 1 is installed at the moving end of the lifting mechanism 2. The support ring mechanism 112 includes a fixed seat 1121, a lifting mechanism 3 1120, a mounting seat 1124, a clamping block 1123, and a mounting plate 1122. The fixed seat 1121 is fixed to the moving end of the lifting mechanism 2 111. The telescopic cylinder type lifting mechanism 3 1120 is installed on the fixed seat 1121. The moving end of the lifting mechanism 3 1120 is connected to the mounting seat 1124 below. A plurality of slide grooves are formed around the center interval at the bottom surface of the mounting seat 1124. Each slide groove is slidably connected to a corresponding clamping block 1123. A mounting plate 1122 is fixed below the mounting seat 1124. The mounting plate is fixed to the mounting seat. The clamping block 1123 extends from a material hole formed at the mounting plate 1122. Each clamping block 1123 slides along a guide slide groove formed on the peripheral wall of the material hole. The clamping block 1123 is connected to the guide slide groove 112 5, an elastic member for resetting, such as a spring, is installed between them. When in use, for example, the vibration plate feeding mechanism 2 is used to feed the first O-ring feeding mechanism, and the horizontal displacement of the horizontal shift mechanism 2 cooperates with the longitudinal displacement of the lifting mechanism 2 to move the support ring mechanism 1 to the required position. When the support ring mechanism moves down to the discharge port of the vibration plate feeding mechanism 2, the O-ring at the discharge port is sleeved on the bottom end portion of the conical shape after the multiple clamping blocks are combined, and the turntable moves the valve stem to this position. The support ring mechanism 1 moves the O-ring to the top of the valve stem. During the downward movement, the valve stem is inserted into the gap between the clamping blocks to open the clamping blocks, so that the O-ring is gradually opened and gradually slides downward to the corresponding position of the valve stem. After the support ring mechanism 1 moves up, the clamping blocks are reset under the action of the elastic member, and the multiple clamping blocks form a closed state, and the corresponding bottom ends are conical.

[0074] The first O-ring feeding mechanism can be increased in number according to demand, such as Figure 2 As shown, in this example, there are two sets of first O-ring feeding mechanisms 11, so as to put two O-rings on different positions of the valve stem.

[0075] For the first unloading mechanism, if Figure 2 , Fig. 9As shown, in this example, the first unloading mechanism 12 includes a screw-type horizontal shift mechanism 3 120, a cylinder-type lifting mechanism 4 121, a cylinder-type rotating mechanism 122, and a cylinder-claw-type clamping mechanism 3 123. The lifting mechanism 4 121 is installed at the moving end of the horizontal shift mechanism 3 120, the rotating mechanism 1 122 is installed at the moving end of the lifting mechanism 4 121, and the clamping mechanism 3 123 is radially installed at the output end of the rotating mechanism 122. The rotating mechanism 1 rotates the clamping mechanism 3 in the longitudinal plane to complete the position adjustment. When the turntable moves the valve stem assembled with the O-ring to the workstation, the horizontal shift mechanism 3 is used for horizontal adjustment, and the lifting mechanism 4 is used for longitudinal adjustment. The rotating mechanism 1 rotates so that the claw end of the clamping mechanism 3 clamps the valve stem at the turntable fixture. The rotating mechanism 1 rotates so that the valve stem at the claw end of the clamping mechanism 3 moves to the slide groove in the first transfer mechanism, and then slides to the valve body assembly mechanism.

[0076] For the valve body assembly mechanism, Figure 1 , Figure 3 As shown, a second turntable mechanism 20, a second valve stem feeding mechanism 23, a valve body feeding mechanism 21, a static valve piece feeding mechanism 27, a dynamic valve piece feeding mechanism 25, a second O-ring feeding mechanism 28, and a second unloading mechanism 29 are installed on the box frame type base 204. The second turntable mechanism also adopts a multi-station turntable machine. The second valve stem feeding mechanism 23, the valve body feeding mechanism 21, the static valve piece feeding mechanism 27, the dynamic valve piece feeding mechanism 25, the second O-ring feeding mechanism 28, and the second unloading mechanism 29 are installed around the turntable on the top surface of the base 204. The materials move with the turntable to the corresponding station, and the functional mechanism of the station performs the corresponding action.

[0077] As for the second valve stem feeding mechanism, its structural composition is consistent with that of the first valve stem feeding mechanism, which will not be described in detail. The dispensing mechanism 16 and the positioning mechanism 38 can also be installed at the discharge port of the first transfer mechanism 4. The positioning mechanism 38 can include a horizontally arranged rotating mechanism 2 and a longitudinally arranged clamping mechanism 7. The rotating mechanism 2 can be such as a rotating cylinder and a cylinder claw-type clamping mechanism 7 can be longitudinally installed at its output end. When in use, the second valve stem feeding mechanism is used to clamp the valve stem at the dispensing mechanism, and then it is moved to the clamping mechanism 7, and the valve stem is clamped by the clamping mechanism 7. The rotating mechanism 2 is used to rotate the clamping mechanism 7, so that the protrusion on the peripheral wall of the clamped valve stem is in the desired position. The process can be controlled by an external video mechanism.

[0078] For the valve body feeding mechanism, if Figure 3 , Fig.10As shown, the valve body feeding mechanism 21 includes a screw-type horizontal shifting mechanism 210, a cylinder-type lifting mechanism 211, and a cylinder-claw-type clamping mechanism 212. The lifting mechanism 211 is installed at the moving end of the horizontal shifting mechanism 210 and the clamping mechanism 212 is installed at the moving end of the lifting mechanism 211. The horizontal shifting mechanism 210 is used for horizontal adjustment, and the lifting mechanism 211 is used for longitudinal adjustment. When in use, the valve body is supplied by the vibration disk feeding mechanism 200, and the position of the clamping mechanism 210 is adjusted by the coordination of the horizontal shifting mechanism 210 and the lifting mechanism 211. For example, the valve body at the discharge port of the vibration disk feeding mechanism 210 is clamped and then moved to the clamping mechanism of the turntable. The clamping mechanism 210 is released to leave the valve body at the clamp and moves with the turntable to the workstation where the second valve stem feeding mechanism is located. The second valve stem feeding mechanism clamps the valve stem assembled with the O-ring from the first transfer mechanism to the barrel cavity of the valve body.

[0079] In addition, it is preferred to add a second positioning mechanism, such as Figure 3 , Fig.11 As shown, a second positioning mechanism 22 is installed between the valve body feeding mechanism 21 and the second valve stem feeding mechanism 23. The second positioning mechanism 22 includes a driving motor 220, a plug column 221, and a telescopic cylinder 222. The telescopic cylinder is arranged longitudinally, and the driving motor 220 is longitudinally installed at the moving end of the telescopic cylinder 222. The plug column 221 is installed at the output end of the driving motor 220. After the second turntable mechanism 20 moves the valve body to a predetermined position, the telescopic cylinder longitudinally adjusts the position of the plug column so that the plug column is inserted into the valve body cavity. The driving motor rotates the plug column to adjust the state of the corresponding valve body so that the groove at the cavity wall of the valve body is in a suitable position. The valve body after the position is adjusted moves with the turntable to the work station where the second valve stem feeding mechanism is located, and the valve stem is installed to the valve body by the second valve stem feeding mechanism.

[0080] In this example, a clamping mechanism 24 is installed between the second valve stem feeding mechanism 23 and the movable valve plate feeding mechanism 25. Figure 3 , Fig.14 As shown, the clamping mechanism 24 includes a telescopic cylinder 241 and a pressing block 242. The pressing block 242 is installed at the moving end of the telescopic cylinder 241. When the turntable moves the valve body to this working position, the telescopic cylinder moves the pressing block downward, and the pressing block moves downward to press the valve stem to complete the docking of the valve body and the valve stem.

[0081] For the moving valve plate feeding mechanism, if Figure 3 , Fig.12As shown, the movable valve plate feeding mechanism 25 includes a screw-type horizontal shifting mechanism five 251, a cylinder-type lifting mechanism six 252 and an adsorption mechanism one 253. The adsorption mechanism one is like a common vacuum suction nozzle type. The lifting mechanism six 252 is installed longitudinally at the moving end of the horizontal shifting mechanism five 251, and the adsorption mechanism one 253 is installed longitudinally at the moving end of the lifting mechanism six 252. The horizontal shifting mechanism five is adjusted horizontally, and the lifting mechanism six is ​​adjusted longitudinally. In coordination with each other, the adsorption mechanism one is placed in a desired position. When in use, if the movable valve plate is supplied by the vibration plate feeding mechanism four, and the adsorption mechanism one absorbs the movable valve plate at the outlet of the vibration plate feeding mechanism four, when the turntable moves the valve body with the valve stem assembled to the workstation, the position of the adsorption mechanism one is adjusted to move the movable valve plate into the valve body cavity.

[0082] For the static valve plate feeding mechanism, if Figure 3 , Fig.13 As shown, the static valve plate feeding mechanism 27 includes a screw-type horizontal shifting mechanism 6 271, a cylinder-type lifting mechanism 7 272 and a cylinder-claw-type clamping mechanism 5 273. The lifting mechanism 7 272 is longitudinally installed at the moving end of the horizontal shifting mechanism 6 271, and the clamping mechanism 5 273 is longitudinally installed at the moving end of the lifting mechanism 7 272. The horizontal shifting mechanism 6 cooperates with the lifting mechanism 7 to adjust the position of the clamping mechanism 5. Due to the structural characteristics of the static valve plate, the clamping claws of the clamping mechanism 5 are horizontally oriented to better clamp the static valve plate. When in use, the static valve plate is supplied by the vibrating plate feeding mechanism 5, and the static valve plate at the feeding port is clamped by the clamping mechanism 5. When the turntable moves the valve body with the movable valve plate assembled to the work station, the position of the clamping mechanism 5 is adjusted so that the clamped static valve plate is in the valve body cavity.

[0083] In order to improve stability, in this example, a dispensing mechanism 26 is installed between the moving valve plate feeding mechanism 25 and the static valve plate feeding mechanism 27. Figure 3 , Fig.16 As shown, the glue dispensing mechanism 26 includes a longitudinal telescopic mechanism 260, a transverse telescopic mechanism 261 and a glue dispensing assembly 262. The transverse telescopic mechanism 261 is installed at the moving end of the longitudinal telescopic mechanism 260, and the glue dispensing assembly 262 is installed at the moving end of the transverse telescopic mechanism 261. The glue dispensing assembly is such as a common telescopic cylinder longitudinally moving glue spray nozzle type. The longitudinal telescopic mechanism and the transverse telescopic mechanism are such as common telescopic cylinders. When the turntable moves to this station, the longitudinal telescopic mechanism and the transverse telescopic mechanism cooperate to adjust the glue outlet position of the glue spray nozzle in the glue dispensing assembly, and then glue is dripped onto the movable valve plate. After the static valve plate is subsequently installed, the static valve plate and the movable valve plate are adhered to each other by the glue liquid.

[0084] As for the second O-ring feeding mechanism, its structural composition is consistent with that of the first O-ring feeding mechanism. The second O-ring feeding mechanism is used to put the O-ring on the valve body, which will not be repeated here. The vibration plate feeding mechanism 6 203 is used to feed the second O-ring feeding mechanism.

[0085] For the second unloading mechanism, if Figure 3 , Fig.15 As shown, the second unloading mechanism 29 includes a screw-type horizontal shifting mechanism 7 290, a cylinder-type lifting mechanism 8 291 and a cylinder-claw-type clamping mechanism 6 292. The lifting mechanism 8 is longitudinally installed at the moving end of the horizontal shifting mechanism 7, and the clamping mechanism 6 is longitudinally installed at the moving end of the lifting mechanism 8. The horizontal shifting mechanism 7 cooperates with the lifting mechanism 8 to adjust the position of the clamping mechanism 6. When the turntable moves the valve body to this station, the valve body is clamped by the clamping mechanism 6, and then moved to the slide groove in the second transfer mechanism, and the valve body moves along the slide groove to the air tightness detection mechanism.

[0086] For airtightness testing organizations, Figure 1 , Figure 4 As shown, the airtightness detection mechanism 3 includes a third turntable mechanism 30, a clamping and feeding mechanism 31, a rubber pad feeding mechanism 32, and an airtightness detection component 33. The third turntable mechanism 30 is also installed on the box frame type base 37. The clamping and feeding mechanism 31, the rubber pad feeding mechanism 32, and the airtightness detection component 33 are installed around the turntable. The third turntable mechanism also adopts a multi-station turntable machine. When the turntable moves the valve body to the required position, the functional mechanism of the position performs the corresponding action.

[0087] As for the clamping feeding mechanism, its composition is consistent with that of the first valve stem feeding mechanism. In this example, batch feeding is performed, and multiple sets of clamping mechanisms are added in parallel. A dividing mechanism is also added at the discharge port of the second transfer mechanism, such as Fig.17 As shown, the material distribution mechanism has multiple grooves 163 formed at intervals on the side of the slider 162, and the corresponding horizontal reciprocating displacement mechanism adopts a screw type to better make the grooves correspond to the receiving grooves 165. After the grooves at the slider are all placed in the valve body, the last groove is offset from the receiving groove to clamp the valve body at the groove to feed the material to the turntable.

[0088] For the rubber pad feeding mechanism, if Figure 4 , Fig.18 As shown, the rubber pad feeding mechanism 32 includes a screw-type horizontal shifting mechanism eight 321, a cylinder-type lifting mechanism nine 322, a clamping positioning mechanism, and an adsorption mechanism two 324. A bracket 320 is installed on a base three, and a horizontal shifting mechanism eight 321 is installed on the bracket. A lifting mechanism nine 322 is longitudinally installed at the moving end of the horizontal shifting mechanism eight, and an adsorption mechanism two 324 is installed at the moving end of the lifting mechanism nine 322. The adsorption mechanism two is like a common vacuum nozzle type.

[0089] The clamping and positioning mechanism includes a clamping plate 325 and a telescopic mechanism 326. Multiple sets of telescopic mechanisms 326 are installed on the bracket 320, such as a common telescopic cylinder, and two sets of clamping plates 325 are installed in parallel on the bracket 320. The telescopic mechanisms 326 are respectively connected to the clamping plates 325. The clamping plates 325 are opened and closed under the drive of the telescopic mechanisms 326. When the turntable moves the valve body to the work station, the clamping plates are driven by the telescopic mechanism to clamp and fix the valve body on the turntable, and the horizontal displacement mechanism eight is used for horizontal adjustment, and the lifting mechanism nine is used for longitudinal adjustment. The position of the adsorption mechanism two is adjusted in coordination to move the adsorbed rubber pad to the end of the valve body. In this example, the rubber pad is fed by the vibration disk feeding mechanism seven 36, and the distribution mechanism 16 is also installed at the discharge port of the vibration disk feeding mechanism seven 36. The distribution mechanism is consistent with the structure of the distribution mechanism at the discharge port of the second transfer mechanism, and multiple sets of corresponding adsorption mechanisms two are installed in parallel.

[0090] In this example, a pressing mechanism 24 is installed between the rubber pad feeding mechanism 32 and the air tightness detection component 33. Figure 4 As shown, the pressing block at the pressing mechanism is correspondingly extended to better press down the multiple rubber pads so that the rubber pads and the valve body are fixed in place.

[0091] As for the air tightness detection component, it can be purchased directly from the market. When the valve body is rotated and moved to the work station, the detection head is moved under the telescopic cylinder into the valve body cavity for detection, such as inflation and auxiliary sensor detection of air pressure type, which will not be elaborated here.

[0092] In this example, in order to facilitate unloading, an unloading pipe 34, an ejecting mechanism 35 and an air blowing mechanism are added. The ejecting mechanism 35 is located below the turntable in the third turntable mechanism 30 and an ejection hole is formed at the corresponding position of the turntable. The unloading pipe 34 is installed at the side of the turntable, and the air blowing mechanism is installed above the unloading pipe 34. The ejecting mechanism is a common telescopic cylinder that moves an ejecting block up and down. When the turntable moves the valve body that has been tested for air tightness to this station, the ejecting mechanism is started to make the ejecting block extend into the ejecting hole to eject the valve body at the turntable fixture. The air blowing mechanism blows air toward the pipe opening of the unloading pipe, so that the ejected valve body tilts toward the pipe opening of the unloading pipe and falls into the unloading pipe. The air blowing mechanism is a type that is connected to an external air outlet mechanism such as an air outlet nozzle, which will not be described in detail.

All technical solutions under the concept of the present invention belong to the protection scope of the present invention.
