Description

Technical Field

[0001] The present invention relates to the technical field of product detection, in particular to a massage bathtub detection production line and a detection method. Background Art

[0002] In recent years, with the improvement of people's living standards, bathtubs that combine bathing and fitness have developed rapidly. Many private homes or high-end hotels are equipped with massage bathtubs. It sprays water through multiple nozzles distributed in the massage bathtub to stimulate various parts of the human body, which can massage muscles, accelerate blood circulation, relieve pain and activate joints.

[0003] In the industry, in order to improve product quality and meet people's needs, massage bathtubs are usually tested for specifications through manual measurement before leaving the factory. The testing content includes product quality testing and safety testing.

[0004] The quality inspection specifically involves leak detection, which involves filling the bathtub with liquid and observing the outer surface of the bathtub to see if there are any water droplets. If there are any, it indicates that the bathtub has a leak. After the inspection is completed, a flipping mechanism is used to flip the bathtub over and pour out the water.

[0005] However, existing water leakage detection systems have the following problems when operating massage bathtubs: massage bathtubs are large in size, and a large amount of water needs to be added when filling the bathtub, which increases the detection time; in addition, the water needs to be poured out after the detection is completed, and the massage bathtub is large in size and weight, so an additional flipping mechanism is required to flip it stably to ensure the safety of the bathtub, which greatly increases the cost investment and difficulty of massage bathtub detection.

[0006] Safety testing specifically checks whether the produced massage bathtubs meet production requirements for size, model, and other aspects. Due to the worker-friendly environment (excessive noise), it's not suitable for workers to conduct long-term safety and functional testing of massage bathtubs. This also requires frequent shift rotations, which slows down the testing process. Summary of the Invention

[0065] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediary, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0066] like Figures 1 to 10 As shown, a massage bathtub inspection production line includes a conveyor line 2, a waterless inspection device, and a safety function inspection device. The conveyor line 2 passes through the waterless inspection device and the safety function inspection device in sequence.

[0067] The water-free detection device includes a frame 1, a water-free detection unit and a transplanting unit 5. The frame 1 is provided on both sides of the conveyor line 2. The water-free detection unit is installed on the frame 1. The transplanting unit 5 is provided between the frame 1 and the conveyor line 2. The transplanting unit 5 is used to transport the massage bathtub on the conveyor line to the water-free detection unit.

[0068] The safety function detection device includes a frame 6, a movable beam 7 and a safety detection unit. The frame 6 is respectively arranged on both sides of the conveyor line 2. The two ends of the movable beam 7 are respectively slidably installed on the frame 6. The movable beam 7 is located above the conveyor line 2. The movable beam 7 can move along the length direction of the frame 6. The safety detection unit is slidably installed on the movable beam 7. The safety detection unit can move along the length direction of the movable beam 7. The lower end of the safety detection unit is used to detect the safety dimensions of the massage bathtub.

[0069] The present invention is equipped with a waterless detection device and a safety function detection device. During testing, a massage bathtub is placed on a conveyor line 2, which first transports the bathtub to the waterless detection device. The massage bathtub is then moved horizontally off the conveyor line 2 by a transfer unit 5. The massage bathtub is then tested for water leaks by the waterless detection unit. During testing, the waterless detection unit does not inject liquid into the massage bathtub. Instead, it seals the bathtub and injects gas into the tub. The leak is detected from the outside of the bathtub to determine whether the massage bathtub is leaking. After using the gas detection method, there is no need to pour out the liquid in the tub before proceeding to the next test, as in the prior art.

[0070] After the test is complete, the transfer unit 5 is driven again to return the massage bathtub on the rack 1 to the conveyor line 2. Under the operation of the conveyor line 2, the massage bathtub after the leak test is transported to the safety function test device, and then the safety test unit is driven to perform a safety test on the massage bathtub. The safety test unit is inverted on the movable crossbeam 7. At this time, the safety test unit can extend into the interior of the massage bathtub for testing. In one embodiment, a camera for image acquisition is provided at the lower end of the safety test unit. The camera captures images of the interior and exterior of the massage bathtub, which are then uploaded to the processor for matching to determine whether the massage bathtub meets the safety size requirements. In addition, because the massage bathtub remains dry and free of water during the front leak test, the image data collected by the camera can avoid the appearance of water marks in the image, which can affect the judgment result.

[0071] It is worth mentioning that a transplanting unit 5 can also be provided at the safety function testing device, which can move the two massage bathtubs horizontally to both sides of the conveyor line 2. The two massage bathtubs can be subjected to simultaneous safety testing by two safety testing units to improve the efficiency of the testing.

[0095] The second sliding connection member 11 includes a slider 1101, which is fixed to the lower surface of the moving beam 7, and the slider 1101 is provided with a groove, which is mounted in cooperation with the first elongated protrusion 1001;

[0096] The power device includes a first motor 1201 and a transmission rod 1202. The first motor 1201 is fixedly installed on the movable beam 7. The rod body of the transmission rod 1202 is transmission-connected to the first motor 1201. The two ends of the transmission rod 1202 extend toward the gantry 601 respectively. A first gear is fixed to the end of the transmission rod 1202, and the first gear is engaged with the first rack 1002.

[0097] In one embodiment of the present invention, a first rack 1002 is provided on the gantry 601. The rotation of the first motor 1201 drives the rotation of the transmission rod 1202. A first gear is provided at each end of the transmission rod 1202, and the first gear meshes with the first rack 1002. Rotating the gears causes the movable crossbeam 7 to move. Simultaneously, when the slider 1101 is installed and mated with the first elongated protrusion 1001, the groove of the slider 1101 fits over the first elongated protrusion 1001, and the edges of the slider 1101 abut against the first elongated protrusion 1001, allowing the slider 1101 to engage the first elongated protrusion. This provides additional support for the movable crossbeam 7 as it moves, reducing the slight up-and-down jitter of the first gear when the first rack 1002 rolls. This ensures more stable movement of the movable crossbeam 7, thereby enhancing the stability of the data collected by the safety testing equipment 9 and improving the stability and effectiveness of safety testing.

[0098] It is worth mentioning that the first elongated protrusion 1001 and the slider 1101 are made of metal because the first elongated protrusion 1001 and the slider 1101 cooperate to achieve the sliding of the movable crossbeam 7. The movable crossbeam 7 is a heavy object and requires a certain degree of support strength from the first elongated protrusion 1001 and the slider 1101. Therefore, the first elongated protrusion 1001 and the slider 1101 need to be made of metal, specifically stainless steel or iron.

[0099] It is worth mentioning that the transmission rod 1202 is formed by a combination of several connecting rods 12021, and the connecting rods 12021 are connected by couplings 12022;

[0100] The movable crossbeam 7 is provided with a plurality of fixed seats 701 at equal intervals. The fixed seats 701 are provided with bearings, and the rod body of the connecting rod 12021 passes through the bearings.

[0101] Since the moving crossbeam 7 spans the conveyor belt, the length of the moving crossbeam 7 becomes longer, and the corresponding transmission rod 1202 that drives the moving crossbeam 7 also becomes longer. The transmission rod 1202 needs to bear the gravity of the moving crossbeam 7 during transmission. The bending moment borne by the relatively long transmission rod 1202 increases as the length of the rod body becomes longer. The increased bending moment is more likely to cause the transmission rod 1202 to break. For this reason, in the present invention, the transmission rod 1202 is composed of several connecting rods 12021 connected by a coupling 12022. By shortening the transmission rod 1202 to several short-distance connecting rods 12021, the bending moment borne is reduced and the service life of the transmission rod 1202 is ensured.

[0102] Preferably, the first sliding connection further includes a first slide groove 1003, wherein the top beam of the gantry 601 is provided with the first slide groove 1003, and the first slide groove 1003 is provided along the length direction of the top beam of the gantry 601;

[0103] The second sliding connection member 11 further includes a first track 1102 , the end of which is fixed to the side of the end of the moving beam 7 , and the left and right sides of the first track 1102 are respectively against the groove wall of the first slide groove 1003 .

[0104] To further improve the stability of the moving beam 7 during movement and ensure the stability and effectiveness of safety testing, the present invention further provides a first chute 1003 on the first gantry 601, and a first crawler 1102 is fixed to the end of the moving beam 7. The left and right sides of the first crawler 1102 respectively abut against the walls of the first chute 1003, so that the horizontal defense line of the first crawler 1102 is limited by the first chute 1003, reducing the horizontal vibration intensity of the moving beam 7 during movement. This makes the movement of the moving beam 7 more stable, and the data collected by the safety testing equipment 9 more stable, improving the stability and effectiveness of safety testing.

[0105] Preferably, the movable beam 7 is provided with two second long protrusions 702, and the two second long protrusions 702 are respectively provided on the two remaining side surfaces of the movable beam 7 except the top surface of the movable beam 7, and the second long protrusions 702 extend along the length direction of the movable beam 7;

[0106] The movable crossbeam 7 is further provided with a second rack 703 , which extends along the length direction of the movable crossbeam 7 ;

[0107] The flip-chip detection robot arm is provided with a second mounting seat 801 and a second motor 802. The second mounting seat 801 is provided with two mounting blocks 8011. The two mounting blocks 8011 are respectively sleeved on the outer surface of the second long protrusion 702. The second motor 802 is fixed to one side of the second mounting seat 801, and a second gear is installed at the output end of the second motor 802. The second gear passes through the second mounting seat 801 and engages with the second rack 703.

[0108] In the present invention, the flip-up detection robot arm is provided with two mounting blocks 8011 on the second mounting base 801. The mounting blocks 8011 are respectively mounted on two different second long protrusions 702. There is no fixed component between the mounting blocks 8011 and the second long protrusions 702. The mounting holes can slide on the second long protrusions 702, thereby enabling the flip-up detection robot arm to slide on the movable crossbeam 7. The other two long protrusions can provide support forces in different directions for the flip-up detection robot arm. In the present invention, a second long protrusion 702 is provided on the side of the movable crossbeam 7, and a second long lifting protrusion is provided on the bottom surface of the movable crossbeam 7, respectively providing horizontal support and vertical limitation for the flip-up detection robot arm. This increases the stability of the flip-up detection robot arm when it moves.

[0109] A second motor 802 is also provided on the second mounting base 801, and a second gear is provided at the output end of the second motor 802. The second gear is driven to rotate by the rotation of the second motor 802, and the second gear is engaged with the second rack 703. At this time, the second gear will move on the second rack 703 along the direction of rotation, driving the flip-chip detection robot arm to move.

[0110] The top surface of the movable beam 7 is provided with a second chute 803, and the second chute 803 extends along the length direction of the movable beam 7;

[0111] A second crawler belt 804 is installed in contact with the second sliding groove 803 , a connecting seat is fixed to one side of the second mounting seat 801 , and one end of the second crawler belt 804 is fixedly connected to the connecting seat.

[0112] To further improve the stability of the flip-down detection robot arm during movement and ensure the stability and effectiveness of safety testing, the present invention further provides a second chute 803 on the movable crossbeam 7, and a second track 804 is fixed to the second mounting seat 801. The left and right sides of the second track 804 respectively abut against the groove walls of the second chute 803, so that the horizontal defense line of the second track 804 is limited by the second chute 803, reducing the horizontal vibration intensity of the flip-down detection robot arm during movement. This makes the movement of the flip-down detection robot arm more stable, the data collected by the safety testing equipment 9 more stable, and the stability and effectiveness of safety testing improved.

[0113] The flip-chip detection robot arm 8 is a multi-axis robot arm with six degrees of freedom.

[0114] The multi-axis robotic arm can achieve vertical positioning, while the six-degree-of-freedom robotic arm can realize rotation. The detection range can cover the horizontal direction, thereby realizing all-round data collection inside the cylinder.
