Description

Technical Field

[0001] The present invention belongs to the technical field of valve assembly equipment, and in particular relates to valve body assembly equipment and an assembly method. Background Art

[0002] The cooling systems of electronic equipment, such as servers, require high-precision valves to control the flow of coolant. Existing valve assembly methods prioritize efficiency over surface integrity, often neglecting the valve seat and valve core. This can easily lead to scratches or micro-damage to these surfaces during assembly. These surface defects can degrade the sealing performance of the assembled valve. Consequently, valves assembled using existing valve assembly equipment are unable to meet the requirements of high-reliability cooling systems. Improved assembly methods are needed to minimize surface damage to components like the valve seat and valve core. Summary of the Invention

[0003] Purpose of the invention: To provide a valve body assembly device and assembly method, which, through the cooperation of the material tray and the conveying mechanism, can fix the position of the valve seat during the loading process without collision, thereby reducing the surface damage of workpieces such as the valve seat and valve core, and solving the problem that the surface damage of workpieces such as the valve seat and valve core is easily caused when assembling the valve body in the prior art.

[0004] The technical solution of the present invention is: a valve body assembly equipment includes: a dividing plate, a valve seat feeding device, a color ring feeding device, a valve seat sleeve sealing ring device, a valve core feeding device, a valve core sleeve sealing ring device, a spring feeding device, a retaining ring gasket feeding mechanism, a pressure testing device and an airtightness testing device.

[0005] The valve seat feeding device, color ring feeding device, valve seat sleeve sealing ring device, valve core feeding device, valve core sleeve sealing ring device, spring feeding device, retaining spring gasket feeding mechanism, pressure testing device and airtightness testing device are distributed around the dividing plate.

[0006] The valve seat loading device and the valve core loading device include: a conveying mechanism and a material tray, the material tray is provided with a plurality of placement slots, the placement slots are used to place workpieces, and the conveying mechanism is used to move the workpieces on the material tray to the indexing plate.

[0007] In a further embodiment, the valve body assembly equipment further includes: a workpiece loading mechanism.

[0008] The workpiece loading mechanism includes: a workpiece moving assembly and a workpiece clamping jaw. Multiple workpiece moving assemblies are distributed around the dividing plate. Two workpiece clamping jaws are installed on each workpiece moving assembly. The position of the workpiece moving assembly is coordinated with the position of the valve seat sleeve sealing ring device, the valve core sleeve sealing ring device, the spring loading device, the pressure testing device and the air tightness testing device.

[0009] The workpiece moving assembly is used to drive the two workpiece clamps to flow between the indexing plate and each device. Through the cooperation of the indexing plate, the workpiece moving assembly and the workpiece clamps, each device can work synchronously when the indexing plate rotates, reducing waiting time and greatly improving work efficiency.

[0010] In a further embodiment, the valve seat loading device and the valve core loading device further include: a tray lateral displacement mechanism, a tray lifting mechanism and a silo.

[0011] The three silos are distributed along the transverse direction, the material tray is arranged in the silo, the conveying mechanism and the material tray transverse displacement mechanism are arranged on one side of the silo, and at least one of the silos is provided with a material tray lifting mechanism.

[0012] The tray lateral displacement mechanism is used to allow the tray to flow between the three silos, and the tray lifting mechanism is used to adjust the height of the tray in the silo. Through the cooperation of the tray lateral displacement mechanism, the silo and the tray, when the conveying mechanism is taking materials from a tray in a silo, the staff can replace the tray in the silo in time without stopping the machine, thereby reducing the surface damage of workpieces such as valve seats and valve cores while ensuring the loading efficiency of workpieces.

[0013] In a further embodiment, the three silos of the valve seat feeding device are respectively a valve seat silo, a valve seat empty disc silo and a valve body finished product silo.

[0014] The material tray in the valve seat silo is used to carry the workpiece, and the transport mechanism is used to obtain the workpiece from the top of the valve seat silo.

[0015] The tray lateral displacement mechanism is used to move the empty tray on the top of the valve seat silo to the valve seat empty tray silo, the tray lateral displacement mechanism is used to move the empty tray in the valve seat empty tray silo to the finished product silo, and the conveying mechanism is used to place the valve body finished product on the tray in the valve body finished product silo, which can enable the conveying mechanism to obtain the valve seat from the tray on the top of the valve seat silo, and enable the tray lateral displacement mechanism to obtain the empty tray from the top of the valve seat silo, so that the empty tray can be moved to the empty tray silo, and then the empty tray can be moved to the valve body finished product silo to be reused to carry the valve body finished product. Compared with the prior art, the circular motion of the dividing plate can be combined with the valve seat loading device to make the empty tray reused, and there is no need to set up two additional areas for unloading, which greatly reduces the volume of the equipment.

[0016] In a further embodiment, the material tray lateral displacement mechanism of the valve core loading device is arranged below the three material bins.

[0017] The tray lifting mechanism of the valve core feeding device includes: a tray vertical cylinder and a tray side stopper. The tray vertical cylinder is installed below the silo, and the tray side stopper is installed on the side of the silo.

[0018] When the tray vertical cylinder is used to raise the tray to a predetermined position, the tray side stop is inserted between the tray and the tray lateral displacement mechanism. Through the cooperation of the tray vertical cylinder and the tray side stop, the trays on the tray lateral displacement mechanism can be stacked step by step.

[0019] In a further embodiment, the color ring feeding device includes: a rotating vibration plate, a discharge guide rail, a discharge linear vibration feeder, a return guide rail, a return linear vibration feeder, a color ring moving mechanism and an outer O-ring assembly clamp.

[0020] The discharging guide rail is arranged at the discharging end of the rotating vibration disk, the discharging linear vibration feeder is installed on the discharging guide rail, the return guide rail is arranged at the feeding end of the rotating vibration disk, the return guide rail is arranged below the discharging guide rail, the return linear vibration feeder is installed on the return guide rail, the color ring moving mechanism is arranged on one side of the discharging guide rail, the outer O-ring assembly clamp is installed on the color ring moving mechanism, and the color ring moving mechanism and the outer O-ring assembly clamp are used to move the color ring on the discharging guide rail to the valve seat.

[0021] The discharge guide rail is provided with a plurality of suction holes, and the suction holes are used to connect a vacuum device.

[0022] The discharging guide rail applies adsorption force to the color circle through the suction hole.

[0023] The discharging linear vibration feeder causes the color circle on the discharging guide rail to move in a direction away from the rotating vibration disk.

[0024] The return material linear vibration feeder causes the color rings on the return material guide rail to move toward the rotating vibration disk, and absorbs the color rings through the suction holes of the guide rail, thereby reducing the probability of the color rings falling off the guide rail. Combined with the discharging linear vibration feeder, the color rings on the discharging guide rail are subjected to vibration in the direction away from the rotating vibration disk, thereby improving the feeding efficiency of the color rings, and solving the problem that the color rings in the prior art are soft in texture, highly elastic, and light in weight, and therefore are easily affected by the vibration of the rotating vibration disk during transportation on the guide rail, resulting in the color rings easily falling off the guide rail at the end of the rotating vibration disk due to excessive vibration amplitude, resulting in low color ring feeding efficiency.

[0025] When the color rings on the discharge guide rail occasionally fall off, the return guide rail can take over the fallen color rings, and the return linear vibration feeder can quickly return the color rings on the return guide rail to the rotating vibration disk, further improving the conveying rhythm of the color rings.

[0026] In a further embodiment, the suction hole distribution area is located at an end of the discharge guide rail away from the rotating vibration disk.

[0027] The length of the suction hole distribution area is ≤ one-third of the total length of the discharge guide rail, which can enable the accumulated flexible rings to fall onto the return guide rail at the end of the discharge guide rail close to the rotating vibration plate and be quickly returned, thereby avoiding the flexible rings from accumulating at the discharge end of the discharge guide rail and interfering with the outer O-ring assembly claw to pick up the material.

[0028] In a further embodiment, the valve body assembly equipment further comprises: a press.

[0029] The spring feeding device and the retaining spring gasket feeding mechanism are arranged on one side of the press.

The valve seat positioning mechanism is arranged below the lifting positioning mechanism, the lifting positioning mechanism is arranged below the pressing mechanism, and the lifting positioning mechanism is provided with a guide hole.

[0031] The spring feeding device is used to place the spring in the valve seat, and the circlip gasket feeding mechanism is used to place the circlip and gasket in the guide hole of the lifting and positioning mechanism.

[0032] The lifting and positioning mechanism and the valve seat positioning mechanism are used to apply a clamping force to the valve seat, and the pressing mechanism is used to press the retaining spring in the guide hole into the valve seat. Compared with the existing technology, the lifting and positioning mechanism and the valve seat positioning mechanism are used to apply a clamping force to the valve seat. The probability of the valve seat deviating laterally and the probability of the spring scratching the inner wall of the valve seat are reduced, and the problem of the existing technology directly using moving components and clamps to install the spring, which is prone to the spring and valve seat deviating laterally and scratching the inner wall of the valve seat, resulting in a decrease in the sealing performance of the assembled valve body.

[0033] In a further embodiment, the lifting and positioning mechanism includes: a lifting power member, a positioning plate, a material blocking power member and a material blocking member.

[0034] The positioning plate is installed on the lifting power member, the guide hole is opened on the positioning plate, and the lifting power member is used to drive the positioning plate to move up and down.

[0035] The material blocking power piece is installed on the positioning plate, and the material blocking piece is installed on the material blocking power piece.

[0036] When the lifting power component drives the positioning plate to move toward the valve seat, the material blocking power component moves the material blocking component to above the guide hole. The material blocking power component can move the material blocking component between the position above the guide hole and the side of the guide hole. When the material blocking component moves to above the guide hole, it can avoid the problem that the spring in the valve seat is pressed to the edge of the positioning plate and then rebounds and pops out of the valve seat on the basis of the lifting positioning mechanism and the valve seat positioning mechanism being used to apply a clamping force to the valve seat.

[0037] The valve body assembly method based on the valve body assembly equipment includes: a plurality of workpiece positioning fixtures are provided on the dividing plate, and the workpiece positioning fixtures on the dividing plate correspond to the positions of the valve seat loading device, the color ring loading device, the valve seat sleeve sealing ring device, the valve core loading device, the valve core sleeve sealing ring device, the spring loading device, the retaining ring gasket loading mechanism, the pressure testing device and the air tightness testing device.

[0038] The indexing plate performs the following operations simultaneously each time it rotates an angle.

[0039] The valve seat loading device moves the unassembled valve seat on the material tray to the workpiece positioning fixture of the indexing plate through the transport mechanism, and moves the finished valve body on the workpiece positioning fixture of the indexing plate to the material tray through the transport mechanism.

[0040] The color ring feeding device sleeves the color ring onto the valve seat.

[0041] The valve seat sleeve sealing ring device sleeves the sealing ring on the valve seat.

[0042] The valve core loading device moves the valve core onto the indexing plate.

[0043] The valve core sealing ring device sleeves the sealing ring on the valve core and places the valve core in the valve seat.

[0044] The spring loading device places the spring in the valve seat.

[0045] The circlip and gasket feeding mechanism places the circlip and gasket in the valve seat to complete the assembly of the valve body product.

[0046] The pressure testing device performs pressure testing on the spring of the finished valve body.

[0047] The airtightness testing device performs an airtightness test on the finished valve body.

[0048] The beneficial effects of the present invention are as follows: the present application places workpieces such as valve seats and valve cores on a material tray, positions the workpieces through placement grooves, and then uses a conveying mechanism to move the workpieces on the material tray to a dividing plate for valve body assembly. Compared with the prior art that uses a vibration plate to load materials, the valve seats and valve cores and other workpieces of the present application are fixed in the placement grooves during the loading process and do not collide, thereby reducing surface damage to workpieces such as valve seats and valve cores, and solving the problem that the prior art easily causes surface damage to valve seats and valve cores when assembling valve bodies.
