Description

Technical Field

[0001] This invention relates to the field of machining technology, and in particular to a short-pipe throttling valve groove pressing process and valve body testing production line. Background Technology

[0002] As a crucial component controlling refrigerant circulation within air conditioners, the demand for short-pipe throttling valves is increasing due to industry development and rising market demand. However, mainstream manufacturing and testing methods face significant bottlenecks.

[0003] Traditional manual processing of short-tube throttle valves is labor-intensive, repetitive, noisy, and inefficient, failing to meet current market demands. Furthermore, current manufacturers primarily use pneumatic testing for product inspection, which differs from actual usage conditions. Ideally, water testing would be used to evaluate the performance of short-tube throttle valves. Therefore, manufacturers urgently need an automated production line capable of both processing and testing short-tube throttle valves to improve production quality and efficiency. Summary of the Invention

[0004] A production line for the grooving process of a short-pipe throttle valve and the valve body inspection process includes:

[0005] The valve body forming device includes a valve body feeding mechanism, a filter screen feeding mechanism, a valve body and filter screen integration mechanism, and a valve body pressing mechanism. The valve body and the filter screen are fed into the production station in the valve body and filter screen integration mechanism, respectively, and are integrated by the valve body and filter screen integration mechanism. Then, the filter screen enters the valve body pressing mechanism and is formed into a short pipe throttling valve by the valve body pressing mechanism.

[0006] Valve body transfer device;

[0007] The valve body testing device includes a robotic arm mechanism, a testing station, a water testing station, an air drying station, and a valve body recycling mechanism. After the valve body forming device produces the short-pipe throttle valve, it is transferred to the testing station via a valve body transfer device. The short-pipe throttle valve is then tested for water quality at the water testing station via the robotic arm mechanism and air-dried at the air drying station. Subsequently, the valve body recycling mechanism places qualified valve bodies into qualified valve body stations and unqualified valve bodies into unqualified valve body stations.

[0008] Furthermore, the valve body feeding mechanism includes a valve body vibrating disc and a valve body guide rail; the valve body guide rail is connected to the production station.

[0009] Furthermore, the filter screen feeding mechanism includes a filter screen vibrating plate and a filter screen guiding track; the filter screen guiding track is connected to the production station.

[0010] Furthermore, the valve body filter integration mechanism includes a production station, a first limiting component, a second limiting component, and a push rod component;

[0011] The production station is equipped with a through-type support groove for placing the valve body and filter screen, and the through-type support groove allows the valve body and filter screen to move axially.

[0012] The first limiting member and the second limiting member are arranged opposite to each other and are located on both sides of the production station, respectively, to limit the filter screen entering the through-type bearing tank;

[0013] The push rod is located on the axial side of the through-type bearing groove. When the valve body and the filter screen enter the through-type bearing groove respectively, the push rod pushes the filter screen into the valve body and pushes the valve body into the valve body pressing mechanism along the through-type bearing groove.

[0014] Furthermore, the valve body pressing mechanism includes a rotary assembly and a pressing assembly;

[0015] The valve body is pushed into the rotary assembly by a push rod and rotates through the rotary assembly.

[0016] The groove pressing assembly is installed above the rotary assembly and can move longitudinally; when the valve body rotates with the rotary assembly, the groove pressing assembly falls and acts on the valve body to perform a groove pressing action on the valve body, forming a short pipe throttle valve.

[0017] Furthermore, the valve body transfer device includes a transfer component and a transfer guide rail;

[0018] The transfer component is installed on the side of the rotary assembly, and the transfer guide rail is installed between the valve body forming device and the valve body detection device;

[0019] The transfer component moves the short-tube throttle valve located on the rotary assembly to the transfer guide rail, where it then enters the valve body detection device.

[0020] Furthermore, the robotic arm mechanism includes a drive unit, a first robotic arm, a second robotic arm, and a third robotic arm; the first robotic arm corresponds to the inspection station and the water inspection station; the second robotic arm corresponds to the water inspection station and the air drying station; the third robotic arm corresponds to the air drying station and the valve body recovery mechanism; the drive unit synchronously drives the first robotic arm, the second robotic arm, and the third robotic arm to move.

[0021] Under the action of the driving component, the first robotic arm transfers the short pipe throttle valve in the inspection station to the water inspection station and performs water inspection; the second robotic arm transfers the water-inspected short pipe throttle valve in the water inspection station to the air-drying station and performs air-drying; the third robotic arm transfers the air-dried short pipe throttle valve in the air-drying station to the valve body recovery mechanism. If the short pipe throttle valve is a qualified valve body, the qualified valve body is placed into the qualified valve body station through the valve body recovery mechanism. If the short pipe throttle valve is an unqualified valve body, the unqualified valve body is placed into the unqualified valve body station through the valve body recovery mechanism.

[0022] Furthermore, the valve body recycling mechanism includes a qualified valve body station, an unqualified valve body station, and a material distribution assembly;

[0023] The material distribution assembly is installed between the qualified valve body station and the unqualified valve body station. When the short pipe throttle valve is a qualified valve body, the third robotic arm places the qualified valve body into the qualified valve body station. When the short pipe throttle valve is an unqualified valve body, the material distribution assembly operates and cooperates with the third robotic arm to guide the unqualified valve body into the unqualified valve body station.

[0024] Furthermore, the water inspection station includes a water inspection base and a water inspection positioning component;

[0025] The water detection positioning components are installed facing each other on both sides of the water detection base; when the short pipe throttle valve is placed on the water detection base, the water detection positioning components position the short pipe throttle valve and perform water detection.

[0026] Furthermore, the air-drying station includes an air-drying base and an air-drying positioning component;

[0027] The air-drying positioning components are installed facing each other on both sides of the air-drying base; when the short pipe throttle valve is placed on the air-drying base, the air-drying positioning components position the short pipe throttle valve and air-dry it.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] 1. Improved production efficiency: The entire process from loading, assembling, and pressing of loose parts to inspection and sorting has been automated, replacing the traditional intermittent production mode of manual operation, and significantly improving production efficiency.

[0030] 2. High product quality consistency: Automated equipment eliminates the technical fluctuations and fatigue errors caused by manual operation. The depth and force of the pressing groove, as well as the assembly position of the filter screen, are all guaranteed by precision cylinders, servo systems, and tooling, ensuring consistent processing parameters for each product and significantly reducing the defect rate.

[0031] 3. Significantly enhanced detection capabilities: By replacing "gas detection" with "water detection," the physical properties of the detection medium (water) are closer to those of actual refrigerant, enabling more effective detection of defects that are difficult to detect with gas detection, such as micro-leakage and insufficient flow.

Detailed Implementation

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] Example 1

[0043] like Figure 1-7 As shown, a short-pipe throttle valve grooving process and valve body inspection production line includes: a valve body forming device 1, a valve body transfer device 2, and a valve body inspection device 3; the valve body forming device 1, the valve body transfer device 2, and the valve body inspection device 3 are all installed on a frame. This production line integrates automatic feeding, grooving, water pressure testing, and automatic sorting into a continuous production line, connecting discrete manual workstations into an automated process.

[0044] In this embodiment, the valve body forming device 1 includes a valve body feeding mechanism 11, a filter screen feeding mechanism 12, a valve body filter screen integration mechanism 13, and a valve body pressing mechanism 14.

[0045] In this embodiment, the valve body feeding mechanism 11 includes a valve body vibrating disc 11a and a valve body guide rail 11b, which is connected to the production station 131. The valve bodies are oriented and sorted by the valve body vibrating disc 11a. The spiral track and screening mechanism inside the valve body vibrating disc 11a ensure that the valve bodies roll axially into the production station 131. The valve bodies roll into the production station 131 through the ramp-shaped outlet of the valve body guide rail 11b. This ramp-shaped outlet of the valve body guide rail 11b has a storage function, capable of buffering several valve bodies to ensure continuous feeding.

[0046] In this embodiment, the filter screen feeding mechanism 12 includes a filter screen vibrating plate 12a and a filter screen guiding track 12b, which is connected to the production station 131. The filter screens are oriented and sorted by the filter screen vibrating plate 12a and then enter the production station 131 through the filter screen guiding track 12b. At this time, the filter screens and the valve body are located on the same axis, waiting for the valve body filter screen integration mechanism 13 to perform subsequent operations.

[0047] In this embodiment, the valve body filter screen integration mechanism 13 includes a production station 131, a first limiting member 132, a second limiting member 133, and a push rod 134. The first limiting member 132 and the second limiting member 133 are arranged opposite to each other and are respectively installed on both sides of the production station 131 where the filter screen is stored. When the filter screen enters the production station 131 via the filter screen guide track 12b, the first limiting member 132 and the second limiting member 133 are adapted to it to ensure that the filter screen can accurately slide into the designated position of the production station 131.

[0048] It should be added that a through-type support groove 131a is provided on the production station 131 for placing the valve body and filter screen, and the through-type support groove 131a allows the valve body and filter screen to move axially.

[0049] The first limiting component 132 includes a first cylinder and a U-shaped limiting piece mounted on the output shaft of the first cylinder. When in use, the first cylinder drives the U-shaped limiting piece to extend from the side into the production station 131. The U-shaped limiting piece cooperates with the through-type bearing groove 131a to form a precise guide groove for receiving the filter screen, ensuring that the predetermined position of the filter screen is coaxial with the valve body.

[0050] The second limiting member 133 includes a second cylinder and a baffle plate mounted on the output shaft of the second cylinder. In use, the second cylinder drives the baffle plate to extend from the side into the production station 131, blocking the upper part of the through-type bearing groove 131a. When a filter screen is already in the through-type bearing groove 131a, the baffle plate blocks it, preventing subsequent filter screens from entering and achieving single-piece feeding.

[0051] After the first cylinder moves the U-shaped limiting plate into position, the second cylinder retracts the baffle plate and releases a filter screen from the filter screen guide track 12b, which falls precisely into the guide groove formed by the U-shaped limiting plate and the through-type bearing groove 131a. Subsequently, the second cylinder drives the baffle plate to extend rapidly, blocking the through-type bearing groove 131a and preventing subsequent filter screens from entering, thus achieving single-screen feeding. Then, the first cylinder drives the U-shaped limiting plate to retract rapidly, making room for the subsequent movement of the push rod 134.

[0052] Furthermore, the push rod component 134 includes a third cylinder and a push rod. The stroke direction of the push rod driven by the third cylinder is consistent with the movement direction of the valve body and the filter screen, so as to ensure that the filter screen can be accurately pushed into the valve body, and further push the valve body into the valve body pressing mechanism 14 for the next pressing action.

[0053] In this embodiment, the valve body pressing mechanism 14 includes a rotary assembly 141 and a pressing assembly 142.

[0054] The rotary assembly 141 is located behind the valve body filter integration mechanism 13. Specifically, the rotary assembly 141 includes a first rotating shaft and a second rotating shaft arranged in parallel horizontally. The first rotating shaft and the second rotating shaft are driven by a synchronous belt transmission system to achieve synchronous opposite rotation. When the valve body moves towards the valve body pressing mechanism 14 in the through-type bearing groove 131a via the push rod 134, it moves exactly onto the first rotating shaft and the second rotating shaft, thereby clamping and driving the valve body to rotate around its own axis.

[0055] The grooving assembly 142 is mounted above the rotary assembly 141. The grooving assembly 142 includes a fourth cylinder and a grooving roller mounted on the output rod of the fourth cylinder. When the valve body rotates on the first and second rotating shafts, the fourth cylinder drives the grooving roller to move towards the outer edge of the valve body and gradually applies pressure to the outer edge of the valve body, eventually rolling an annular groove into the outer edge of the valve body and permanently securing the internal filter screen by material plastic deformation.

[0056] It should be added that the outer ring of the groove roller is preferably made of tungsten steel. The high hardness of tungsten steel ensures that it rolls out annular grooves on the outer edge of the valve body.

[0057] In this embodiment, the valve body transfer device 2 includes a transfer component 21 and a transfer guide rail 22. The transfer component 21 is installed on the side of the rotary assembly 141, and the transfer guide rail 22 is installed between the valve body forming device 1 and the valve body detection device 3. The transfer component 21 transfers the short-tube throttle valve located on the rotary assembly 141 to the transfer guide rail 22, and then it enters the valve body detection device 3.

[0058] In this embodiment, the valve body detection device 3 includes a robotic arm mechanism 31, a testing station 32, a water testing station 33, a drying station 34, and a valve body recovery mechanism 35. The robotic arm mechanism 31 is responsible for performing synchronous actions on the testing station 32, the water testing station 33, the drying station 34, and the valve body recovery mechanism 35. After production by valve body forming device 1, the short-tube throttle valve is transferred to inspection station 32 via valve body transfer device 2. The short-tube throttle valve undergoes water inspection at water inspection station 33 via robotic arm mechanism 31. After the water inspection of the short-tube throttle valve is completed, robotic arm mechanism 31 sends the water-inspected short-tube throttle valve to air drying station 34 for air drying. After the air drying of the short-tube throttle valve is completed, robotic arm mechanism 31 sends the air-dried short-tube throttle valve to valve body recovery mechanism 35. Water inspection station 33 determines whether the short-tube throttle valve is a qualified valve body, and valve body recovery mechanism 35 places qualified valve bodies into qualified valve body station 351 and unqualified valve bodies into unqualified valve body station 352.

[0059] In this embodiment, the robotic arm mechanism 31 includes a drive unit 311, a first robotic arm 312, a second robotic arm 313, and a third robotic arm 314. The drive unit 311 can be configured with a cylinder and a synchronization frame, wherein the output shaft of the cylinder is fixedly connected to the synchronization frame. The first robotic arm 312, the second robotic arm 313, and the third robotic arm 314 are all mounted on the synchronization frame, and the cylinder drives the first robotic arm 312, the second robotic arm 313, and the third robotic arm 314 to move synchronously through the synchronization frame. The first robotic arm 312 corresponds to the inspection station 32 and the water inspection station 33; the second robotic arm 313 corresponds to the water inspection station 33 and the air drying station 34; and the third robotic arm 314 corresponds to the air drying station 34 and the valve body recovery mechanism 35.

[0060] It should be added that, under the action of the cylinder, the first robotic arm 312 transfers the short-pipe throttle valve in the inspection station 32 to the water inspection station 33 and performs a water inspection operation. The second robotic arm 313 transfers the water-inspected short-pipe throttle valve in the water inspection station 33 to the air-drying station 34 and performs an air-drying operation. The third robotic arm 314 transfers the air-dried short-pipe throttle valve in the air-drying station 34 to the valve body recovery mechanism 35. If the short-pipe throttle valve is a qualified valve body, the qualified valve body is placed into the qualified valve body station 351 through the valve body recovery mechanism 35. If the short-pipe throttle valve is a defective valve body, the defective valve body is placed into the defective valve body station 352 through the valve body recovery mechanism 35.

[0061] In this embodiment, the water inspection station 33 includes a water inspection base 331 and a water inspection positioning component 332. The water inspection positioning component 332 is installed facing each other on both sides of the water inspection base 331. When the short pipe throttle valve is placed on the water inspection base 331, the water inspection positioning component 332 positions the short pipe throttle valve and performs water inspection. The water inspection positioning component 332 includes two sixth cylinders and a water inspection positioning valve block installed on the output shaft of the sixth cylinder. The water inspection positioning valve block is provided with a water inspection notch for the two ends of the short pipe throttle valve to extend into, and the water inspection positioning valve block is also integrally formed with a water inspection pipe port that communicates with the water inspection notch.

[0062] It should be added that when the short pipe throttle valve is placed on the water detection base 331, the two sixth cylinders drive the corresponding water detection positioning valve blocks to move toward the short pipe throttle valve until the two ends of the short pipe throttle valve are tightly attached to the notch of the water detection positioning valve block and a sealing state is formed.

[0063] Water inspection station 33 is also equipped with a water inspection device. The two ends of the water inspection device are connected to the water inspection port of the water inspection positioning valve block through flexible hoses to perform water inspection operations.

[0064] In this embodiment, the drying station 34 includes a drying base 341 and a drying positioning component 342. The drying positioning component 342 is installed facing each other on both sides of the drying base 341. When the short pipe throttle valve is placed on the drying base 341, the drying positioning component 342 positions the short pipe throttle valve and dries it. The drying positioning component 342 includes two seventh cylinders and a drying positioning valve block installed on the output shaft of the seventh cylinders. The drying positioning valve block is provided with a drying notch for the two ends of the short pipe throttle valve to extend into, and the drying positioning valve block is also integrally formed with a drying pipe port that communicates with the drying notch.

[0065] It should be added that when the short pipe throttle valve is placed on the air-drying base 341, the two seventh cylinders drive the corresponding air-drying positioning valve blocks to move toward the short pipe throttle valve until the two ends of the short pipe throttle valve are tightly attached to the notch of the air-drying positioning valve block and a sealing state is formed.

[0066] At the 34th drying station, there is also a drying device. The two ends of the drying device are connected to the drying port of the drying positioning valve block through flexible hoses to carry out the drying operation and ensure that the valve body is dry.

[0067] In this embodiment, the valve body recovery mechanism 35 includes a qualified valve body station 351, an unqualified valve body station 352, and a material distribution assembly 353. The material distribution assembly 353 is installed between the qualified valve body station 351 and the unqualified valve body station 352. When the short-pipe throttle valve is a qualified valve body, the third robotic arm 314 places the qualified valve body into the qualified valve body station 351. When the short-pipe throttle valve is an unqualified valve body, the material distribution assembly 353 operates and cooperates with the third robotic arm 314 to guide the unqualified valve body into the unqualified valve body station 352.

[0068] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
