S32The servo cylinder 120 is moved to a second designated position, and the liquid catalyst is sprayed in the area where the rectangular seal ring 20 is placed.
The catalyst spraying mechanism 160 is used for spraying liquid catalyst to form a catalyst spraying area A, and the catalyst dosage of the spraying area and the running track of the nozzle are accurately controlled by controlling the distance between the spraying head and the sprayed object.
S33And the servo cylinder 120 is moved to a third designated position, and the adhesive is applied to the annular area of the block cover 30. The area of the blocking cover 30 coated with the adhesive is equal to or slightly larger than the area between the inner diameter and the outer diameter of the rectangular sealing ring 20.
The glue is applied by controlling the glue amount with a flow valve, and the glue is applied by the glue applying mechanism 170 to form a glue applying region B.
The rectangular sealing ring is provided with a gap space in the rectangular annular groove of the shell, and after the bonding glue is extruded by the blocking cover, the bonding glue is filled in the gap space to fully connect the shell, the rectangular sealing ring and the blocking cover.
S34And the servo electric cylinder 120 moves to a fourth designated position, the vision system 130 detects that the gluing position of the adhesive glue is correct, and the servo electric cylinder 120 returns to the original point after the gluing is finished. Said step S34Including detecting the glue application trajectory by the vision system 130, ensuring that the trajectory has no break points.
S4And the closing cap 30 is assembled by the turning cylinder mechanism 110, the transferring cylinder mechanism 140, and the servo press 150.
Wherein, the step S4The method also comprises the following steps:
S41the overturning cylinder mechanism 110 is opened, the blocking cover 30 overturns for 180 degrees, the transferring cylinder mechanism 140 ascends, the overturning cylinder mechanism 110 is closed in a vacuum suction mode, and the blocking cover 30 is transferred to the transferring cylinder mechanism 140.
S42The transplanting cylinder mechanism 140 is opened by vacuum suction and lowered, and then the transplanting cylinder mechanism 140 is moved to the left right under the servo press 150.
S43The servo press 150 descends to the first designated position, the transplanting cylinder mechanism 140 is closed by vacuum suction, the vacuum suction on the pressure head is opened, and the blocking cover 30 is switched to the pressure head of the servo press 150.
S44The servo press 150 moves up to the second designated position, and the transplanting cylinder mechanism 140 moves right and descends to the initial position.
S45And the servo press 150 descends to the third designated position, the blocking cover 30 is pressed into the shell 10, and after the pressing, the servo press 150 returns to the original point. Wherein a circular groove is provided on the housing 10, into which the cap 30 is pressed. That is, the outer edge of the cap 30 is press-fitted into the housing 10, and the cap 30 is press-fitted into the circular groove with interference.
According to the above description, in the method for assembling the blocking cover of the regenerative braking energy recovery device, the casing 10 serves as a main body of the speed reducer assembly, the rectangular sealing ring 20 serves as a sealing connection part between the casing 10 and the blocking cover 30, and the rectangular structure is adopted to mainly increase the sealing contact area between the rectangular sealing ring 20 and the blocking cover 30 and improve the sealing reliability. The plug 30 is made of a material having good plastic deformation.
For better sealing, an adhesive is applied to the cover surface of the rectangular sealing ring 20 and to the region of the housing sealing ring groove. The adhesive has an anaerobic effect, does not cure when in contact with oxygen or air, and rapidly polymerizes to form a crosslinked solid polymer once isolated from oxygen or air. The adhesive glue can be well applied to the sealing process of the speed reducer assembly.
In addition, a liquid catalyst is used for further accelerating the curing time of the adhesive and enhancing the adhesive force among the housing 10, the rectangular sealing ring 20 and the cap 30. The liquid catalyst has the capability of increasing the bonding activity of the metal surface, has the characteristic of quick volatilization, can be volatilized within twenty seconds, and can be matched with bonding glue to better improve the bonding and sealing performance.
Additionally, in order to ensure that a large acting force exists between the rectangular sealing ring 20 and the blocking cover 30, the outer edge of the blocking cover 30 is pressed into the shell 10 by the blocking cover 30 in an interference press-fitting mode, and the blocking cover 30 generates plastic deformation in the process of being pressed into the shell 10, so that a certain pressing force is ensured, the blocking cover 30 is prevented from being accidentally loosened, and a certain mechanical protection effect is achieved.
Further, the rectangular ring groove of the housing 10 should have a size slightly larger than that of the rectangular sealing ring 20, so that the rectangular sealing ring 20 has a certain clearance space in the rectangular ring groove of the housing 10. After the adhesive is extruded by the blocking cover 30, the adhesive is automatically filled into the gap space, so that the shell 10, the rectangular sealing ring 20 and the blocking cover 30 are fully connected, and the overall adhesion and sealing performance is improved.
In view of the above description, the method for assembling the plug of the regenerative braking energy recovery device according to the present invention has the following points:
firstly, for coating the adhesive glue, the reliable and stable accuracy of the glue output quantity needs to be ensured, the flow valve control is adopted, the glue width and the glue thickness of the adhesive glue are strictly controlled, the proper diameter of a glue nozzle is selected, and the sealing performance and the leakage-free phenomenon are ensured. After the adhesive glue is coated, the gluing track needs to be detected through a visual image system, so that no breakpoint exists in the annular track, and the glue width is proper. The size of the gluing area is equal to or slightly larger than the area between the inner diameter and the outer diameter of the rectangular sealing ring 2.
Secondly, for spraying the liquid catalyst, the dosage of the catalyst in a spraying area and the running track of a nozzle need to be accurately controlled. Meanwhile, if the distance between the spray head and the sprayed object is controlled well, the spraying area is too close to be possibly too concentrated, the volatilization effect is not facilitated, and the spraying area is too dispersed too far, so that the bonding activity capability of the surface of the shell cannot be enhanced. Meanwhile, the ventilation and exhaust device can be selected and installed according to the actual operation environment.
Thirdly, to the extrusion deformation of blanking cover, need guarantee the plane degree of blanking cover punching press face, the too warping in surface can influence the rubber coating width and the thickness of gluing, also can influence the extrusion deformation power of blanking cover. Meanwhile, in the process that the plug is pressed into the circular groove of the shell, the yield force and displacement of a pressure curve need to be monitored, and the plastic deformation of the plug is ensured to meet certain performance indexes.
The method for assembling the blocking cover of the regenerative braking energy recovery device successfully puts the method into the existing energy accumulator assembly line body after the process verification through earlier multi-group test comparison, and has reliable process.
