In today's world, where people pursue leisure and aesthetics, the bathroom has become an essential place for relaxation. Within the traditional bathroom experience, bathtub massage systems are popular as a key element that enhances bathroom functionality. However, the manufacturing of traditional bathtub massage systems presents some issues with production efficiency and assembly quality, particularly regarding the connection and assembly between the nozzle holder and the threaded pressure plate.

[0003] In a traditional bathtub massage system, the components of a bathtub massage nozzle usually include a nozzle seat and a nozzle core seat threadedly connected to it.

The threaded pressing piece is installed in the nozzle seat by screws. However, many workshops install the threaded pressing piece into the threaded hole opened in the nozzle seat by screwing the screws manually, which leads to low production efficiency and unstable assembly quality. In order to improve the production efficiency of the threaded pressing piece pressed and assembled into the nozzle seat and ensure the assembly quality, it is necessary to invent a nozzle pressing piece screwing machine that can be automatically produced.

DETAILED DESCRIPTION

[0025] The embodiments described below are only a part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0026] See Figure 1 、 Figure 4 , this embodiment 1 provides a nozzle pressing screw machine, including a mounting frame 10, a screw feeding mechanism 20 is provided on one side of the mounting frame 10, the screw feeding mechanism 20 is connected to a screw conveying pipe 11, the end of the screw conveying pipe 11 is connected to a screw placing mechanism 30, the screw placing mechanism 30 is connected to a first horizontal conveying component 40, a negative pressure adsorption mechanism 50 is provided on the side of the screw placing mechanism 30, a rotary crimping mechanism 60 is connected above the negative pressure adsorption mechanism 50, a rotary nozzle placing mechanism 70 is provided below the negative pressure adsorption mechanism 50, a material picking mechanism 80 is provided on the side of the negative pressure adsorption mechanism 50, and a material drop port is provided below the material picking mechanism 80.

[0027] Preferably, the screw feeding mechanism 20 is provided with an air blowing mechanism for blowing the screws in the screw feeding mechanism 20 into the screw delivery tube 11. During use, the screws are placed in the screw feeding mechanism 20, and then the motion guide rails in the screw feeding mechanism 20 transport the screws in an orderly manner to the two discharge ports provided in the screw feeding mechanism 20. The air blowing mechanism provides air pressure to blow the two screws at the discharge ports into the screw delivery tube 11. The screws then reach the screw placement mechanism 30 through the screw delivery tube 11.

[0028] See Figure 3Preferably, the screw placement mechanism 30 includes a placement platform 31, and two screw placement slots 32 are provided on the placement platform 31. The two screw placement slots 32 are used to receive screws delivered from the screw delivery tube 11; the placement platform 31 is connected to the delivery end of the first horizontal conveying component 40, and the first horizontal conveying component 40 can drive the placement platform 31 to move in the horizontal direction so as to accurately move the screws in the screw placement slots 32 to the position below the rotary crimping mechanism 60, thereby facilitating the negative pressure adsorption mechanism 50 to adsorb the screws, ensuring that the screws can be accurately positioned to the position where they need to be assembled, thereby improving the accuracy and efficiency of assembly.

[0029] Preferably, the rotary crimping mechanism 60 includes a lifting cylinder 61 and two servo motors 62. The output end of the lifting cylinder 61 and the output end of the servo motor 62 are arranged toward one side of the rotating nozzle placement mechanism. The lifting cylinder 61 is fixed on the mounting frame. The output end of the lifting cylinder 61 is connected to a mounting plate 63. Two servo motors 62 are arranged on the mounting plate 63. The output end of the servo motor 62 is connected to the negative pressure adsorption mechanism 50.

[0030] Furthermore, an adjustment plate 64 is provided at the bottom of the mounting plate 63, and a connecting shaft 65 is provided at the bottom of the mounting plate 63. The adjustment plate is provided with a sliding hole, and the connecting shaft 65 is slidably disposed in the sliding hole. A stopper 66 is provided at the bottom of the connecting shaft 65, and a spring 67 is sleeved on the top outer side of the connecting shaft 66. When the output end of the lifting cylinder 61 of the present application extends, it drives the mounting plate 63 downward, and the connecting shaft 65 at the bottom of the mounting plate follows the downward movement. The spring on the outer side of the connecting shaft 65 is compressed, thereby driving the adjustment plate 64 downward, after which the screw tightening operation can be carried out. When the output end of the lifting cylinder 61 contracts, the spring 67 on the outer side of the connecting shaft 66 rebounds, and the stopper 66 provided at the bottom of the connecting shaft 65 drives the adjustment plate 64 upward.

[0031] Preferably, the negative pressure adsorption mechanism 50 includes a pair of negative pressure suction tubes 51, each of which is connected to a negative pressure machine through an air pipe 68. The two negative pressure suction tubes 51 are connected to the output ends of the two servo motors 62 on one side through a universal shaft 52. It should be noted that in this application, two negative pressure suction tubes 51 are connected by two servo motors to achieve a dual-axis design, which can simultaneously adsorb and tighten two screws, thereby improving production efficiency. At the same time, in this application, the servo motor 62 and the negative pressure suction tube 51 are arranged side by side.

[0032] It should be noted that in this application, the first horizontal conveying component 40 is also connected to a second lifting cylinder 12. When it is necessary to pick up screws, the second lifting cylinder 12 drives the first horizontal conveying component 40 downward, so that the height of the screw placement mechanism 30 is lower than the bottom height of the negative pressure suction tube 51. Then the first horizontal conveying component 40 drives the screw placement mechanism 30 to the bottom of the negative pressure suction tube 51. After that, the second lifting cylinder 12 drives the first horizontal conveying component 40 upward, so that the screws in the screw placement mechanism 30 are in contact with the negative pressure suction tube 51. The negative pressure machine provides negative pressure, and then the screws on the screw placement mechanism 30 are adsorbed onto the negative pressure suction tube 5. After the screws are adsorbed on the negative pressure adsorption mechanism 50, the second lifting cylinder 12 drives the first horizontal conveying component 40 downward for a certain distance, so that the screws can naturally fall out of the screw placement slot 32 of the placement platform 31, and then the first horizontal conveying component 40 drives the placement platform 31 to reset. The output end of the lift cylinder 61 then descends, allowing the screw on the negative pressure adsorption mechanism 50 to contact the threaded holes in the pressing plate and the nozzle holder 90 (the pressing plate is provided with screw insertion holes in this application). The servo motor 62 then rotates to match the continued downward movement of the lift cylinder 61, driving the screw into the threaded hole until it is fully tightened. Once the screw is tightened, the output end of the lift cylinder 61 retracts upward, driving the negative pressure adsorption mechanism 50 away from the nozzle holder 90.

[0033] Preferably, a screwdriver bit is provided at the bottom of the negative pressure suction tube 51. The screwdriver bit is connected to the output end of the servo motor and is used to be inserted into the cross slot of the screw, so that the servo motor can drive the screw to rotate and screw in.

[0034] See Figure 2 Preferably, the rotating nozzle placement mechanism 70 includes a circular rotating disk 71, and four nozzle placement positions 72 are equidistantly arranged above the circular rotating disk 71. The bottom of the circular rotating disk 71 is connected to a rotating assembly. During use, the operator manually places the nozzle holder 90 with the threaded pressing piece placed inside on one of the nozzle placement positions 72, and then the circular rotating disk 71 rotates to drive the nozzle placement position 72 with the nozzle holder 90 placed therein to be located below the rotary crimping mechanism 60. When the rotary crimping mechanism 60 operates on the nozzle holder 90 located below, the staff can place the nozzle holder 90 with the threaded pressing piece placed therein on other nozzle placement positions 72. After the screws are tightened, the circular rotating disk 71 rotates to drive the screwed nozzle holder 90 to the unloading station, and the next nozzle placement position 72 with the nozzle holder 90 placed therein rotates to the bottom of the rotary crimping mechanism 60, thereby realizing continuous automatic operation.

[0035] Preferably, a cylindrical placement position 73 is provided in the middle of the nozzle placement position 72, and a placement slot 74 is provided on both sides of the cylindrical placement position 73, and the two placement slots 74 have different hole spacings. In the present application, the nozzle holder 90 includes a water inlet 91 and an air inlet 92. The water inlet 91 and the air inlet 92 have different diameters. Therefore, the water inlet 91 with a larger diameter is aligned and placed in the placement slot 74 with a larger hole spacing, while the air inlet 92 with a smaller diameter is placed in the placement slot 74 with a smaller hole spacing. At this time, the nozzle holder 90 is limited, which facilitates the subsequent screw tightening work.

[0036] Preferably, the material-retrieving mechanism 80 includes a second horizontal conveying assembly 81, a vertical conveying assembly 82 disposed at the output end of the second horizontal conveying assembly 81, and a clamping assembly 83 disposed at the output end of the vertical conveying assembly 82. The output end of the clamping assembly 83 is provided with a manipulator 84. Furthermore, the first horizontal conveying assembly 40 and the second horizontal conveying assembly 81 are each a displacement cylinder, the vertical conveying assembly 82 is a press-fitting cylinder, and the clamping assembly 83 is a clamping cylinder.

[0037] It should be noted that when unloading, the second horizontal conveying component 81 drives the vertical conveying component 82 and the clamping component 83 to move above the nozzle seat 90 with the screws tightened, and then the vertical conveying component 82 drives the clamping component 83 downward to the nozzle seat 90. At this time, the opened manipulator 84 clamps the nozzle seat 90 through the contraction of the clamping component 83, and then the vertical conveying component 82 moves upward, thereby driving the nozzle seat 90 to separate from the nozzle placement position 72. Then, the second horizontal conveying component 81 drives the vertical conveying component 82 and the clamping component 83 to move to the unloading port, the clamping component 83 opens, and then the manipulator 84 follows to open, and the nozzle seat 90 completes unloading.

[0038] Preferably, the negative pressure adsorption mechanism 50 is provided with a sensor assembly comprising a pickup detection sensor and a downward pressure sensor. It should be noted that the pickup detection sensor is an infrared sensor used to detect whether a screw has been adsorbed; the downward pressure sensor is a laser position sensor that monitors the downward pressure stroke of the lifting cylinder 61 in real time, thereby determining whether the screw has been perfectly rotated into the threaded hole of the nozzle holder 90 based on the downward pressure stroke, greatly improving the accuracy of product quality control.

[0039] Preferably, the present application also includes a foot switch 85 for controlling start and stop.

[0040] Preferably, in the present application, an adjustment component is further provided, which is connected to the two negative pressure suction tubes 51 to adjust the distance between the two negative pressure suction tubes 51, thereby facilitating the assembly of nozzle sheets of different sizes.

[0041] Preferably, a PLC control system is also provided in the present application, and the PLC control system accurately controls the torque and speed of the two servo motors to ensure the consistency of product production.

[0042] The utility model provides a nozzle pressing and screwing machine, which realizes a fully automated assembly process of a thread pressing sheet 93 and a nozzle holder 90 through the cooperation of a screw storage mechanism, a screw placement mechanism 30, a first horizontal conveying assembly 40, a negative pressure adsorption mechanism 50, a rotary crimping mechanism 60, a rotary nozzle placement mechanism 70 and a material picking mechanism 80 contained therein. During use, the operator manually places the thread pressing piece in the nozzle holder 90 and places the nozzle holder 90 at the nozzle placement position 72 of the rotating nozzle placement mechanism 70. Subsequently, the rotating nozzle placement mechanism 70 drives the nozzle holder 90 to rotate to the bottom of the rotary crimping mechanism 60. At the same time, the screws in the screw storage mechanism are transported to the screw placement mechanism 30 through the screw delivery pipe 11. Then, the first horizontal conveying assembly 40 drives the screw placement mechanism 30 to move to the bottom of the rotary crimping mechanism 60. The rotary crimping mechanism 60 adsorbs the screws at the screw storage mechanism. Then, the first horizontal conveying assembly 40 drives the screw placement mechanism 30 back to its original position. After that, the rotary crimping mechanism 60 drives the screws on the negative pressure adsorption mechanism 50 downward to the threaded holes of the thread pressing piece and the nozzle holder 90. The negative pressure adsorption mechanism 50 presses down and rotates to screw the screws in, thereby realizing a fully automated assembly process of the thread pressing piece and the nozzle holder 90. After the screws are screwed in, the rotary crimping mechanism 60 drives the negative pressure adsorption mechanism 50 upward to reset, and the material removal mechanism 80 unloads the nozzle holder 90. The above steps can then be repeated. Therefore, the nozzle pressing and screwing machine not only automates the production process and improves production efficiency, but also reduces the intensity of manual operation, ensures product consistency and assembly quality, and significantly improves the competitiveness of the production line.

[0043] The above disclosures are merely some preferred embodiments of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention are still within the scope covered by the present invention.
