[0081] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0082] Example 1:

[0083] like Figures 1-3 As shown, a smart manufacturing process for a refrigeration valve body includes the following steps:

[0084] Step a, feeding: The refrigeration valve body 00 to be processed is poured into the feeding box 1 for temporary storage. The refrigeration valve body 00 is T-shaped and includes a first valve port 001 located in the middle and a second valve port 002 and a third valve port 003 located on both sides.

[0085] Step b, sorting: The refrigeration valve bodies 00 in the feeding box 1 are transferred to the vibrating plate 3 by the chain conveyor 2 for sorting.

[0086] Step c, clamping and transfer: the refrigeration valve bodies 00, after being sorted by the vibrating plate 3, are transported one by one in an orderly manner to the bottom of the robot arm 4, where the robot arm 4 grabs and transfers them to the turntable 5, where the clamps 6 of the turntable 5 clamp and fix them.

[0087] Step d: First tapping. The turntable 5 carries the clamped refrigeration valve body 00 and rotates to transport it. The refrigeration valve body 00 is transferred to the first tapping mechanism 7, which performs tapping on the first valve port 001.

[0088] Step e, secondary tapping: After the tapping of the first valve port 001 is completed, the turntable 5 loads the refrigeration valve body 00 and rotates it to the bottom of the second tapping mechanism 8, which then taps the second valve port 002 located above the refrigeration valve body 00.

[0089] Step f: After the second valve port 002 is tapped three times, the turntable 5 loads the refrigeration valve body 00 and rotates it to the bottom of the third tapping mechanism 9. Simultaneously, the fixture 6 drives the refrigeration valve body 00 to rotate, switching the positions of the second valve port 002 and the third valve port 003. The third tapping mechanism 9 then performs tapping on the third valve port 003.

[0090] Step g, Output: After the tapping of the third valve port 003 is completed, the turntable 5 drives the refrigeration valve body 00 to rotate to the initial position, and the robot arm 4 grabs and transfers it for output.

[0091] Specifically, the refrigeration valve body 00 in the application is a three-way refrigeration valve body, and the first valve port 001, the second valve port 002 and the third valve port 003 on the refrigeration valve body all need to be tapped to form threads so that the refrigeration valve body can be applied to a refrigeration system and assembled directly through threaded connection.

[0092] Further, the manufacturing process of the existing refrigeration valve body 00 is as follows:

[0093] Method 1: manual operation, once the tapping of each pair of valve ports on the refrigeration valve body 00 is completed, the refrigeration valve body 00 is disassembled and clamped again for tapping again, and the tapping of all valve ports on the refrigeration valve body 00 is completed in turn.

[0094] Method 2: the technical solution of the application with the application number CN201710112137.X in the background art is adopted, the first valve port 001 and the second valve port 002 (the first valve port 001 and the second valve port 002 are two valve ports not located at the bottom) of the refrigeration valve body 00 are tapped, and after the tapping of the two valve ports is completed, the tapping of the third valve port 003 located at the bottom is completed by manual operation.

[0095] Both of the above manufacturing processes involve manual intervention, resulting in low processing efficiency and low manufacturing precision. Therefore, the application adopts a fully automatic intelligent manufacturing process, and the three valve ports of the refrigeration valve body 00 are completed in a synchronous processing program without manual intervention, and all processing actions are automatically processed by automatic equipment.

[0096] Embodiment 2:

[0097] The difference between Embodiment 2 and Embodiment 1 of the application is described with reference to Embodiment 1.

[0098] As shown in Figures 4-16 , in steps c-d, the refrigeration valve body 00 is transferred and the position of the valve port of the refrigeration valve body 00 is switched by cooperation of the turntable 5 and the clamp 6.

[0099] Specifically, the rotating disc 5 is rotationally arranged, a motorized main shaft is installed below the rotating disc 5, the rotating disc 5 is driven to rotate by the motorized main shaft, four groups of the clamps 6 are uniformly distributed on the circumference of the rotating disc 5, the clamps 6 correspond to the loading and unloading station 51, the first tapping station 52, the second tapping station 53 and the third tapping station 54 in sequence, the loading and unloading station 51 is arranged opposite to the mechanical arm 4, the mechanical arm 4 can automatically load and unload the refrigeration valve body 00 at the loading and unloading station 51, the first tapping station 52 is arranged opposite to the first tapping mechanism 7, the first tapping mechanism 7 performs tapping processing on the first valve port 001 in the horizontal direction at the first tapping station 52, the second tapping station 53 is located below the second tapping mechanism 8, the second tapping mechanism 8 performs tapping processing on the second valve port 002 in the vertical direction at the second tapping station 53, the third tapping station 54 is located below the third tapping mechanism 9, the third tapping mechanism 9 performs tapping processing on the third valve port 003 in the vertical direction at the third tapping station 54, and the tapping processing of the three valve ports of the refrigeration valve body 00 is directly and one-time completed on the rotating path of the rotating disc 5.

[0100] In the present application, in order to directly and one-time complete the tapping processing of the three valve ports of the refrigeration valve body 00 on the rotating path of the rotating disc 5, the second valve port 002 and the third valve port 003 need to be transposed, and the conventional design idea is to drive the clamp to rotate by a motor, so that the second valve port 002 and the third valve port 003 can be switched, but no matter whether the clamp is directly driven to rotate by the motor or the clamp is driven to rotate by the motor in cooperation with a gear reduction box, the problem of loss of tapping precision of the refrigeration valve body exists during tapping processing, for example, if the clamp is directly driven to rotate by the motor, the motor main shaft is subjected to stress factors, which can cause the clamp to jump and result in loss of precision, and for another example, if the clamp is driven to rotate by the motor in cooperation with a gear reduction box, the gap between the gears can cause the clamp to be electric, resulting in loss of tapping precision.

[0101] Therefore, the clamp 6 in the present application preferably comprises a pneumatic gripper 61, a lifting and rotating assembly 62 and a locking assembly 63.

[0102] The pneumatic gripper 61 clamps the refrigeration valve body 00, the pneumatic gripper 61 is rotationally switched along the axis of the first valve port 001, the pneumatic gripper 61 adopts a conventional pneumatic finger structure, and the difference lies in that a clamping groove 612 adapted to the shape of the refrigeration valve body 00 is arranged on a clamping block 610 of the pneumatic gripper 61.

[0103] The lifting and rotating assembly 62 is installed on the rotating disc 5, and the lifting and rotating assembly 62 drives the pneumatic gripper 61 to rotationally switch.

[0104] The locking assembly 63 is installed on the rotating disc 5, which locks the pneumatic clamp hand 61 after rotation switching. Through the structure of the locking assembly 63, the stability of the clamp is maintained, and the clamp is prevented from jumping.

[0105] Further, the lifting and rotating assembly 62 comprises a lifting cylinder 621, a lifting seat 622, a gear 623 and a rack 624.

[0106] The lifting cylinder 621 is vertically installed on the rotating disc 5 and is pushed upward.

[0107] The lifting seat 622 is installed on the pushing end of the lifting cylinder 621, and the pneumatic clamp hand 61 is rotatably installed on the lifting seat 622.

[0109] The rack 624 is fixedly installed on the locking assembly 63, and the rack 624 is arranged on one side of the gear 623 and is arranged in meshing with the gear 623.

[0110] It should be noted that in the process of lifting and moving the lifting seat 622 by the lifting cylinder 621, the pneumatic clamp hand 61 is rotated and switched by the cooperation between the gear 623 and the rack 624. Specifically, at the loading and unloading station 51, the axes of the second valve port 002 and the third valve port 003 of the refrigeration valve body 00 arranged above are horizontally arranged, while at the primary tapping station 52 and the secondary tapping station 53, the axes of the second valve port 002 and the third valve port 003 are vertically arranged, and the second valve port 002 is located above. At the third tapping station 54, the axes of the second valve port 002 and the third valve port 003 are vertically arranged, and the third valve port 003 is located above. Therefore, when the loading and unloading station 51 is switched to the primary tapping station 52, the lifting cylinder 621 rotates and switches the pneumatic clamp hand 61 by 90°, and when the secondary tapping station 53 is switched to the third tapping station 54, the lifting cylinder 621 rotates and switches the pneumatic clamp hand 61 by 180°. In other words, at the loading and unloading station 51, the lifting cylinder 621 is at 1 / 2 of its stroke, and the lifting cylinder 621 is a two-section pushing and retracting structure. For details, see the structure disclosed in the Chinese Utility Model Patent with the Application No. CN202210927111.1.

[0111] Further, the specific structure of the locking assembly 63 comprises a fixed plate 631, a sliding block group 632, a limiting tooth 633, a limiting block 634, a pushing block 635, a square block 636 and a clamping strip 637.

[0112] The fixed plate 631 is fixedly installed on the rotating disc 5, the lifting seat 622 is slidingly arranged relative to the fixed plate 631 through the sliding block group 632, and the rack 624 is vertically fixedly installed on the fixed plate 631;

[0114] The limiting blocks 634 are provided in two groups, each group of limiting blocks 634 corresponds to a group of limiting teeth 633, and each group of limiting blocks 634 includes two symmetrically arranged limiting blocks 634, the limiting blocks 634 block the limiting teeth 633 from being popped out, and the limiting blocks 634 are all floatingly installed on the fixed plate 631, the limiting block 634 is composed of an integral limiting pin 6341, a hemispherical extrusion part 6342, a block body 6343 and a spring 6344, the limiting pin 6341 limits the limiting teeth 633, the extrusion part 6342 is extruded with the push block 635 to unlock the limiting pin 6341, the block body 6343 is provided with a waist-shaped groove, the limiting pin is inserted into the waist-shaped groove, and the spring 6344 provides the floating capability for the limiting block 634;

[0115] The push block 635 is arranged in one-to-one correspondence with the limiting block 634, the push block 635 moves with the lifting seat 622, the push block 635 extrudes the limiting block 634 to release the limiting teeth 633 from being popped out, the limiting teeth 633 are clamped with the gear 623 to limit the rotation freedom of the pneumatic clamping hand 61, the push block 635 is installed on the sliding block of the lifting seat 622, and the push block 635 can only extrude the corresponding extrusion part 6342 in one direction, that is, when the push block 635 above the sliding block extrudes the corresponding extrusion part 6342 above, the push block 635 is limited by the corresponding fixed block 6350 and cannot rotate and swing, so that the push block 635 compresses the extrusion part 6342, but when the push block 635 in this group moves downward and contacts the extrusion part 6342, the push block 635 is not limited by the fixed block 6350 and can rotate and swing to avoid extrusion of the extrusion part 6342, correspondingly, when the push block 635 below the sliding block extrudes the corresponding extrusion part 6342 below, the push block 635 can compress the extrusion part 6342, but when the push block 635 in this group moves upward and contacts the extrusion part 6342, the push block 635 rotates and swings to avoid extrusion of the extrusion part 6342, and the push blocks 635 arranged above and below the sliding block are connected through the hook spring 6351, so that the rotating and swinging push block 635 can be reset immediately after passing through the corresponding extrusion part 6342;

[0116] The block 636 is installed on the rotating shaft 611, and the block 636 rotates synchronously with the rotating shaft 611;

[0118] It needs to be emphasized that after the lifting cylinder 621 drives the pneumatic clamp hand 61 to rotate to a specified angle, the lifting cylinder 621 still drives the pneumatic clamp hand 61 to move a distance, so that the block 636 is clamped with the clamping strip 637, the rotation degree of freedom of the pneumatic clamp hand 61 is locked, and the jumping of the pneumatic clamp hand 61 during the tapping processing is avoided, and after the lifting cylinder 621 drives the pneumatic clamp hand 61 to rotate to a specified angle (the gear 623 is separated from the cooperation of the rack 624), the limiting tooth 633 is triggered first, so that the limiting tooth 633 is clamped with the gear 623, the dislocation rotation of the gear 623 when separating from the cooperation of the rack 624 is avoided, and the triggering of the limiting tooth 633 depends on the pressing of the dial block 635 on the limiting block 634, and the limiting tooth 633 is unlocked and released.

[0119] Specifically, the limiting tooth 633 is slidably arranged on the slide rail of the slide block group 632, initially, the limiting tooth 633 is blocked and limited by the limiting block 634, and the corresponding elastic member 638 is also in a compressed state, when the limiting tooth 633 is unlocked and released, the limiting tooth 633 is quickly clamped with the gear 623 by the elastic force of the elastic member 638, the gear 623 is preliminarily locked, and then when the block 636 is clamped with the clamping strip 637, the gear 623 is completely locked, and the pneumatic clamp hand 61 is completely locked, due to the preliminary locking of the limiting tooth 633 and the complete locking of the block 636, the pneumatic clamp hand 61 does not jump during the tapping processing, and is more stable.

[0120] It is further explained that no matter in the first tapping station 52, the second tapping station 53 or the third tapping station 54, the lifting cylinder 621 plays a role of lifting and stabilizing the lower part of the pneumatic clamp hand 61, and the two-point clamping of the block 636 and the clamping strip 637 forms three-point fixed cooperation with the lifting of the lifting cylinder 621, so that the pneumatic clamp hand 61 is completely limited and fixed, and does not jump, and at this time, the gear 623 is separated from the cooperation of the rack 624, and the problem of gear gap does not exist, and the jumping problem of the gear 623 during the tapping processing is avoided.

[0121] Embodiment 3:

[0122] It is further explained that no matter in the first tapping station 52, the second tapping station 53 or the third tapping station 54, the lifting cylinder 621 plays a role of lifting and stabilizing the lower part of the pneumatic clamp hand 61, and the two-point clamping of the block 636 and the clamping strip 637 forms three-point fixed cooperation with the lifting of the lifting cylinder 621, so that the pneumatic clamp hand 61 is completely limited and fixed, and does not jump, and at this time, the gear 623 is separated from the cooperation of the rack 624, and the problem of gear gap does not exist, and the jumping problem of the gear 623 during the tapping processing is avoided.

[0123] As shown in Figures 17-18 The first tapping mechanism 7 includes a mounting base 71, a linear module 72 and a tapping tap 73. The mounting base 71 is fixedly arranged. The linear module 72 is horizontally mounted on the mounting base 71. The linear module 72 drives the tapping tap 73 to move horizontally. The tapping tap 73 is driven to rotate by a corresponding motor 74. The linear module 72 is an electric linear module. The electric linear module is a conventional technical structure. That is, the motor drives the screw to rotate, and then the screw nut seat on the screw moves. Therefore, the redundant description is not given here. The linear module 72 drives the tapping tap 73 to insert into the first valve port 001. The motor 74 drives the tapping tap 73 to complete the tapping processing of the first valve port 001. The motor 74 is preferably a servo motor.

[0124] The second tapping mechanism 8 and the third tapping mechanism 9 each include a mechanical arm 81 and an electric tapping tap 82. The mechanical arm 81 is fixedly arranged. The mechanical arm 81 is freely swingable and has degrees of freedom in the X-axis, the Y-axis and the Z-axis. The electric tapping tap 82 is mounted on the freely swingable end of the mechanical arm 81. The electric tapping tap 82 is vertically arranged downward. The mechanical arm 81 drives the electric tapping tap 82 to insert downward into the second valve port 002 or the third valve port 003 to perform tapping processing. Thus, the three groups of valve ports of the refrigeration valve body 00 are automatically completed tapping processing.

[0125] Through the cooperation of the first tapping mechanism 7, the second tapping mechanism 8 and the third tapping mechanism 9, the first valve port 001, the second valve port 002 and the third valve port 003 on the refrigeration valve body 00 are automatically tapped.

[0126] Embodiment 4:

[0127] The difference between the embodiment 4 and the embodiment 1 is described with reference to the embodiment 1.

[0128] As shown in Figures 19-24 In step a, the bottom of the feeding box 1 is provided with a discharge port 11. The discharge port 11 is provided with a hinge door assembly 12 for controlling the discharge. The discharge port 11 is located above the input end of the chain conveyor 2. The discharge port 11 outputs the refrigeration valve body 00 in the feeding box 1. However, due to the structure of the refrigeration valve body 00, the refrigeration valve body 00 is easily blocked at the discharge port 11. Therefore, the hinge door assembly 12 is used to switch and control the discharge port 11. The first hinge plate 1221 and the second hinge plate 1222 are hingedly arranged. The first hinge plate 1221 switches and controls the discharge port 11. The second hinge plate 1222 forms a swing effect and adjusts the refrigeration valve body 00 at the discharge port 11 to avoid the refrigeration valve body 00 from being blocked at the discharge port 11.

[0129] Specifically, the hinged door assembly 12 comprises a hinged mounting plate 121, a hinged plate set 122 and a driving cylinder 123.

[0130] The hinged mounting plate 121 is fixedly installed above the discharge port 11.

[0131] The hinged plate set 122 is swingingly installed above the hinged mounting plate 121, and comprises a first hinged plate 1221 and a second hinged plate 1222 which are hingedly arranged.

[0132] The driving cylinder 123 is installed on the hinged mounting plate 121, and the extension end of the driving cylinder 123 is connected with the first hinged plate 1221, and the driving cylinder 123 drives the hinged plate set 122 to rotate and swing.

[0133] The driving cylinder 123 drives the first hinged plate 1221 to rotate, thereby controlling the opening and closing of the discharge port 11. When the first hinged plate 1221 closes the discharge port 11, the second hinged plate 1222 is arranged in abutment with the inclined plate at the bottom of the discharge port 11. When the first hinged plate 1221 opens the discharge port 11, the second hinged plate 1222 is in a swing state.

[0134] Further, in order to ensure the stability of the output of the refrigeration valve body 00 and the grasping quality of the manipulator 4 on the refrigeration valve body 00, the end of the output channel 31 of the vibration disc 3 is provided with a clamping and positioning assembly 32 for positioning and fixing the refrigeration valve body 00. The clamping and positioning assembly 32 comprises a clamping seat 321, pneumatic clamping jaws 322 and a translation cylinder 323. The clamping seat 321 is provided with a V-shaped loading groove 3211 for loading the refrigeration valve body 00. The pneumatic clamping jaws 322 are arranged on both sides of the loading groove 3211 and clamp the refrigeration valve body 00 in the loading groove 3211. The translation cylinder 323 is horizontally arranged through a mounting seat 324, and the extension end of the translation cylinder 323 is provided with the clamping seat 321 and the pneumatic clamping jaws 322.

[0135] In addition, the end of the output channel 31 of the vibration disc 3 is provided with a blocking assembly 33 for blocking and limiting the refrigeration valve body 00. The blocking assembly 33 comprises a blocking seat 331, a blocking cylinder 332 and a blocking plate 333. The blocking seat 331 is arranged on one side of the output channel 31. The blocking cylinder 332 is vertically installed on the blocking seat 331 and located above the output channel 31. The pushing end of the blocking cylinder 332 is provided with the blocking plate 333. The blocking cylinder 332 drives the blocking plate 333 to descend, thereby blocking and limiting the refrigeration valve body 00 output from the output channel 31.

[0136] Furthermore, to prevent the refrigeration valve body 00 from being gripped by the robotic arm 4, a clamping assembly 34 is provided at the end of the output channel 31 of the vibrating plate 3 to clamp and position the refrigeration valve body 00 located at the very end of the output channel 31. The clamping assembly 34 includes a clamping seat 341, a clamping cylinder 342, and a clamping block 343. The clamping seat 341 and the blocking seat 331 are arranged side by side. The clamping cylinder 342 is installed on the top of the clamping seat 341. The clamping cylinder 342 drives the clamping block 343 to penetrate into the output channel 31 to clamp and position the refrigeration valve body 00 at the very end.

[0137] Specifically, after the refrigeration valve body 00 is transported to the end of the output channel 31, the clamping assembly 34 first clamps and positions the refrigeration valve body 00. Then, the mounting base 321, driven by the translation cylinder 323, moves directly to connect with the output channel 31. At the same time, the blocking cylinder 332 in the blocking assembly 33 drives the blocking plate 333 to descend, limiting the end of the mounting base 321 that is not connected with the output channel 31. The clamping assembly 34 then releases, and the end of the output channel 31... The refrigeration valve body 00 is transferred to the loading groove 3211 on the clamping seat 321 and blocked by the baffle plate 333. Then, the pneumatic gripper 322 clamps the refrigeration valve body 00. After clamping, the blocking cylinder 332 drives the baffle plate 333 to retract and reset. Then, the translation cylinder 323 moves the refrigeration valve body 00 directly below the robot arm 4 for the robot arm 4 to grasp. At the same time, the clamping assembly 34 clamps and fixes the refrigeration valve body 00 located at the end of the output channel 31 again.

[0138] Furthermore, a sensor for detecting the refrigeration valve body 00 is provided at the very end of the output channel 31. Once the sensor detects that the refrigeration valve body 00 is in place, the clamping and positioning assembly 32, the blocking assembly 33, and the clamping assembly 34 will perform their designated actions in sequence.

[0139] Example 5:

[0140] Referring to Example 1, the difference between Example 5 and Example 1 lies in the following:

[0141] like Figures 25-26 As shown, in steps c and g, the robotic arm 4 simultaneously loads the refrigeration valve body 00 to be processed onto the clamp 6 of the turntable 5 and outputs the processed refrigeration valve body 00.

[0142] The robotic arm 4 includes a base 41, a robotic arm 42, and a gripper 43;

[0143] The base 41 is fixedly arranged, the mechanical arm 42 is installed on the top of the base 41, the mechanical arm 42 is freely telescopic and height-adjustable, two groups of the clamping jaws 43 are symmetrically arranged, the clamping jaws 43 are all installed on the freely movable end of the mechanical arm 42, and one group of the clamping jaws 43 grasps the refrigeration valve body 00 to be processed, and the other group grasps the refrigeration valve body 00 processed.

[0144] It should be noted that when the mechanical arm 4 grasps the refrigeration valve body 00 to load the clamp 6, the refrigeration valve body 00 processed is also unloaded and output, and the specific operation steps are that the refrigeration valve body 00 processed is first unloaded from the clamp 6 by the blank group of the clamping jaws 43, then the refrigeration valve body 00 to be processed is loaded on the clamp 6 by the other group of the clamping jaws 43, the refrigeration valve body 00 is clamped and fixed by the clamp 6, then the mechanical arm 4 transfers the refrigeration valve body 00 processed to the frame, resets, and grasps the next group of the refrigeration valve body to be processed.

[0145] The above only describes the preferred embodiment of the present application and is not used to limit the present application, and any modification, equivalent replacement and improvement within the spirit and principle of the present application should be included in the protection scope of the present application.
