[0034] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0035] like Figure 1 As shown, an embodiment of the present application discloses an automobile ABS valve assembly device, including a first pressing mechanism 1 for pressing a valve seat and a valve core, a second pressing mechanism 2 for pressing a magnetic isolation tube onto a valve seat and valve core assembly, a third pressing mechanism 3 for pressing a steel ball onto a moving iron, a fourth pressing mechanism 4 for assembling a moving iron steel ball assembly, a spring and a fixed iron into a valve seat and valve core magnetic isolation tube assembly to form a semi-finished product, a fifth pressing mechanism 5 for pressing a filter into a semi-finished product to form a pressure reducing valve, a detection mechanism 6 for detecting the gap between the moving iron and the fixed iron, a laser welding mechanism 7 for welding and fixing the fixed iron and the magnetic isolation tube, and a marking mechanism 8 for marking the pressure reducing valve.

[0036] Specifically, during the work, the valve seat and the valve core are manually placed in the first pressing mechanism 1 respectively, and the first pressing mechanism 1 presses the valve seat and the valve core to form a valve seat and valve core assembly. After the pressing is completed, the valve seat and valve core assembly and the magnetic isolation tube are manually placed in the second pressing mechanism 2 for pressing. At the same time, the steel ball and the moving iron can be manually placed in the third pressing mechanism 3 for pressing to form a moving iron steel ball assembly. Then, the moving iron steel ball assembly, spring and fixed iron are manually assembled into the valve seat and valve core magnetic isolation tube assembly and pressed into a semi-finished pressure reducing valve through the fourth pressing mechanism 4. Then, the filter screen and the semi-finished pressure reducing valve are manually pressed into a finished pressure reducing valve through the fifth pressing mechanism 5. Then, the assembled finished pressure reducing valve is manually placed in the detection mechanism 6 to detect the gap between the moving iron and the fixed iron. If the product is qualified, the product is taken and placed in the laser welding mechanism 7 for welding in a circle so that the fixed iron and the magnetic isolation tube are welded and fixed. Finally, the welded pressure reducing valve product is placed in the marking mechanism 8 for marking.

[0037] This structure can realize automatic press-fitting of various parts during assembly through the setting of multiple press-fitting mechanisms. At the same time, when the moving iron steel ball assembly, spring and fixed iron are assembled into the valve seat valve core magnetic isolation tube assembly, it can automatically detect whether the spring is press-fitted, thereby reducing the possibility of missing the spring. At the same time, the gap between the moving iron and the fixed iron can be detected through the setting of the detection mechanism 6, thereby ensuring the quality of the product.

[0038] In this embodiment, the first pressing mechanism 1 includes a first mounting frame 101, a first lower fixture 102 for placing a valve seat is arranged at the bottom of the first mounting frame 101, a first lower pressing plate 103 is arranged above the first lower fixture 102, a first lower pressing driving mechanism 104 for driving the first lower pressing plate 103 to perform lifting and lowering movements is fixed on the first pressing mechanism 1, a first upper fixture 105 for placing a valve core is arranged at the bottom of the first lower pressing plate 103, a first guide column 106 is also arranged at the bottom of the first mounting frame 101, the first lower pressing plate 103 is slidably connected to the first guide column 106 through a first guide sleeve, a first limiting column 107 is also arranged at the bottom of the first mounting frame 101, and a first limiting screw 108 cooperating with the first limiting column 107 is arranged on the first lower pressing plate 103.

[0039] Specifically, during assembly, the valve seat is manually placed in the first lower jig 102, and the valve core is placed in the first upper jig 105. The first downward pressure drive mechanism 104 drives the first upper jig 105 to move toward the first lower jig 102, so that the valve core in the first upper jig 105 is pressed down and clamped in the valve seat to complete the assembly. The above-mentioned downward pressure distance can be controlled by the first limit column 107 and the first limit screw 108. When the first limit column 107 and the first limit screw 108 are in contact, the first upper jig 105 cannot continue to move downward.

[0040] The above structure can realize automatic installation of the valve core and the valve seat. At the same time, through the cooperation of the first limit column 107 and the first limit screw 108, the downward pressure distance of the first upper fixture 105 can be controlled, thereby preventing excessive downward pressure from causing damage to the product.

[0041] In this embodiment, the second pressing mechanism 2 includes a second mounting frame 201, a second lower fixture 202 for placing the magnetic isolation tube is arranged at the bottom of the second mounting frame 201, a second lower pressing plate 203 is arranged above the second lower fixture 202, a second lower pressing driving mechanism 204 for driving the second lower pressing plate 203 to perform lifting and lowering movements is fixed on the second pressing mechanism 2, a second upper fixture 205 for placing the valve seat and valve core assembly is arranged at the bottom of the second lower pressing plate 203, a second guide column 206 is also arranged at the bottom of the second mounting frame 201, the second lower pressing plate 203 is slidably connected to the second guide column 206 through a second guide sleeve, a second limiting column 207 is also arranged at the bottom of the second mounting frame 201, and a second limiting screw 208 cooperating with the second limiting column 207 is arranged on the second lower pressing plate 203.

[0042] Specifically, during assembly, the magnetic isolation tube is manually placed in the second lower jig 202, and the valve seat and valve core assembly is placed in the second upper jig 205. The second downward pressure drive mechanism 204 drives the second upper jig 205 to move toward the second lower jig 202, so that the valve seat and valve core assembly in the second upper jig 205 is pressed down and clamped in the magnetic isolation tube to complete the assembly. The above-mentioned downward pressure distance can be controlled by the second limit column 207 and the second limit screw 208. When the second limit column 207 and the second limit screw 208 are in contact, the second upper jig 205 cannot continue to move downward.

[0043] The above structure can realize the automatic installation of the magnetic isolation tube and the valve seat valve core assembly. At the same time, through the cooperation of the second limit column 207 and the second limit screw 208, the downward pressure distance of the second upper fixture 205 can be controlled, thereby preventing excessive downward pressure from causing damage to the product.

[0044] In this embodiment, the third pressing mechanism 3 includes a third mounting frame 301, a third lower fixture 302 for placing a moving iron is arranged at the bottom of the third mounting frame 301, a third lower pressing plate 303 is arranged above the third lower fixture 302, a third pressing driving mechanism 304 for driving the third lower pressing plate 303 to perform lifting and lowering movements is fixed on the third pressing mechanism 3, a third upper fixture 305 for pressing the steel ball down into the moving iron is arranged at the bottom of the third lower pressing plate 303, a third guide column 306 is also arranged at the bottom of the third mounting frame 301, the third lower pressing plate 303 is slidably connected to the third guide column 306 through a third guide sleeve, a third limiting column 307 is also arranged at the bottom of the third mounting frame 301, a third limiting screw 308 cooperating with the third limiting column 307 is arranged on the third lower pressing plate 303, and a first detection camera 309 for detecting whether the steel ball is pressed into place is also arranged on one side of the third lower fixture 302.

[0045] Specifically, during assembly, the moving iron is manually placed in the third lower fixture 302, and the steel ball is placed at the installation position of the moving iron. Then the third downward pressing drive mechanism 304 drives the third upper fixture 305 to move toward the third lower fixture 302, so that the steel ball is pressed into the moving iron to complete the assembly. The above-mentioned downward pressing distance can be controlled by the third limiting column 307 and the third limiting screw 308. When the third limiting column 307 and the third limiting screw 308 are in contact, the third upper fixture 305 cannot continue to move downward. After the steel ball is pressed, the first detection camera 309 can detect whether the steel ball is pressed into place.

[0046] The above structure can realize the automatic installation of the steel ball and the moving iron. At the same time, through the cooperation of the third limit column 307 and the third limit screw 308, the downward pressing distance of the third upper fixture 305 can be controlled, thereby preventing damage to the product due to excessive downward pressure. At the same time, through the setting of the first detection camera 309, it is possible to detect whether the steel ball is pressed into place. If it is not pressed into place, the product can be reworked to ensure the yield rate of the product.

[0047] In this embodiment, the fourth press-fitting mechanism 4 includes a fourth mounting frame 401, a fourth lower fixture 402 for placing the valve seat and valve core magnetic isolation tube assembly is provided at the bottom of the fourth mounting frame 401, and a first displacement sensor 403 extending into the fourth lower fixture 402 is provided at the bottom of the fourth lower fixture 402;

[0048] A fourth lower pressing plate 404 is arranged above the fourth lower fixture 402, a fourth pressing driving mechanism 405 for driving the fourth lower pressing plate 404 to perform lifting and lowering motion is fixed on the fourth pressing mechanism 4, a fourth upper fixture 406 for placing fixed iron is arranged at the bottom of the fourth lower pressing plate 404, the fourth upper fixture 406 comprises a fixture seat 407, a first annular coil 408 is arranged inside the fixture seat 407, a fourth O-ring 409 for clamping the product is arranged inside the fixture seat 407 below the first annular coil 408, and a pressing head 410 is also arranged in the middle of the first annular coil 408;

[0049] A fourth guide column 411 is also provided at the bottom of the fourth mounting frame 401, and the fourth lower pressure plate 404 is slidably connected to the fourth guide column 411 through a fourth guide sleeve. A fourth limiting column 412 is also provided at the bottom of the fourth mounting frame 401, and a fourth limiting screw 413 cooperating with the fourth limiting column 412 is provided on the fourth lower pressure plate 404.

[0050] Specifically, during assembly, the assembled magnetic isolation tube and valve seat valve core assembly are manually placed in the fourth lower fixture 402 first. At this time, the steel ball abuts against the contact of the first displacement sensor 403, and the contact is in a compressed state. Then the installed moving iron steel ball assembly is placed in the magnetic isolation tube, and then a spring is placed in the magnetic isolation tube. Then the fixed iron is placed in the fourth upper fixture 406. At this time, the fixed iron is clamped by the fourth O-ring 409. Then, the fourth downward pressure driving mechanism 405 drives the fourth upper fixture 406 to move toward the fourth lower fixture 402, so that the fixed iron in the fourth upper fixture 406 is pressed down and clamped in the magnetic isolation tube to complete the assembly. At this time, the spring is located between the fixed iron and the moving iron. Then, the first annular coil 408 is energized to generate a magnetic field, so that the moving iron is adsorbed by the fixed iron and moves upward. At this time, the first displacement sensor 403 will generate a displacement change. When the first annular coil 408 stops energizing, the moving iron is reset under the action of the spring, and the first displacement sensor 403 detects another displacement change, thereby realizing the detection of whether the spring is installed. At the same time, the above-mentioned downward pressing distance can be controlled by the fourth limiting column 412 and the fourth limiting screw 413. When the fourth limiting column 412 and the fourth limiting screw 413 are in contact, the fourth upper fixture 406 cannot continue to move downward.

[0051] This structure can realize the assembly of two moving iron steel ball assemblies, springs and fixed iron into the valve seat and valve core magnetic isolation tube assembly, and at the same time can realize the detection of whether the spring is installed, thereby ensuring the product yield.

[0053] Specifically, during assembly, the filter is manually placed in the fifth lower fixture 502, and the semi-finished pressure reducing valve is placed in the fifth upper fixture 505. Then the fifth downward pressure driving mechanism 504 drives the fifth upper fixture 505 to move toward the fifth lower fixture 502, so that the semi-finished pressure reducing valve is pressed and assembled with the road network.

[0054] The above structure can realize the automatic installation of the filter screen and the semi-finished pressure reducing valve, thereby improving the assembly efficiency.

[0056] Specifically, the finished pressure reducing valve is placed in the sixth lower fixture 601, and the second annular coil 602 is energized to generate a magnetic field, so that the moving iron moves toward the fixed iron direction and is attracted, and the sixth driving mechanism 604 drives the detection fixture 603 to move downward, so that the detection end of the second displacement sensor 605 extends into the product and contacts the steel ball. Then the second annular coil 602 is powered off, and the moving iron is reset under the action of the spring, and the moving iron drives the steel ball to move, so that the second displacement sensor 605 detects a displacement signal, and the displacement distance is the distance between the moving iron and the fixed iron.
