[0002] The water pipe hose used in the bathroom is a component used to connect water pipes. The joint assembly and testing of the existing water pipe hose are all completed manually. Manual operation is labor-intensive, materials are easily mixed, assembly efficiency is low, and quality cannot be guaranteed. Therefore, the production cost is high.

[0003] Therefore, the Chinese patent publication number is CN214729938U, and the authorization announcement date is November 16, 2021. It discloses a braided hose assembly production line, including an air supply mechanism, a tube cutting mechanism, a conveying mechanism and an assembly mechanism. A tube cutting mechanism is provided at the end of the conveying mechanism, and multiple assembly mechanisms are arranged in sequence on the same side of the conveying mechanism; the air supply mechanism supplies compressed air to the tube cutting mechanism and the assembly mechanism; the tube cutting mechanism cuts the braided hose roll placed on the discharge tray into braided hoses of equal length; the conveying mechanism receives the braided hose cut by the tube cutting mechanism and conveys it to the input end of multiple assembly mechanisms; the assembly mechanism assembles the braided hoses cut into equal lengths with steel sleeve joints, presses the tubes into shape, performs airtightness testing and finished product packaging and conveys them to the next process.

[0004] The above patent uses tube cutting, connector assembly and crimping, airtightness testing and packaging processes to complete the braided hose processing. The assembly mechanism is increased or decreased according to production needs. The structure is simple, which reduces the labor intensity of workers and improves assembly efficiency and product qualification rate. However, there is no inspection on whether the connector and the braided hose are assembled in place, so the product quality cannot be guaranteed. Summary of the Invention

[0005] The present invention aims to overcome the problem that the product quality of the braided hose cannot be guaranteed during the assembly process in the prior art, and provides a braided hose automatic assembly detection device and detection method that can ensure the product quality.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A braided hose automatic assembly and detection device, which includes a plurality of braided hoses, a conveying platform, an airtightness detection platform, an X-ray detection platform, a collection frame and a truss, wherein the conveying platform is provided with an assembly station and a detection station, and the assembly station and the detection station are distributed in sequence along the conveying direction of the conveying platform, the detection station, the airtightness detection platform, the X-ray detection platform and the collection frame are distributed in sequence along the length direction of the truss and are all located at the bottom of the truss, the top of the truss is provided with a mechanical gripper, the mechanical gripper is slidably connected to the truss, the conveying platform is provided with a plurality of limit members that are transmitted along the conveying direction and are evenly distributed, and the bottom of the limit member is provided with a plurality of limit members that are transmitted along the conveying direction and are evenly distributed. The part is connected to the conveying platform, the braided hose is limited at the top of the limiter, the limiter is provided with a rectangular metal frame, the limiter is located in the metal frame, the metal frame is rotatably connected to the side wall of the limiter, the side wall of the conveying platform is provided with a mounting groove corresponding to the detection station, and a plurality of cylinders corresponding to a plurality of braided hoses on the detection station are detachably installed in the mounting groove, and a magnet is fixed on the output end of the cylinder, one end of the metal frame is located directly below the braided hose, and the mechanical gripper is located above the braided hose, and the other end of the metal frame corresponds to the corresponding magnet up and down.

[0008] The conveying platform is provided with an assembly station and an inspection station, and the assembly station and the inspection station are distributed in sequence along the conveying direction of the conveying platform. The inspection station, airtightness inspection station, X-ray inspection station and collection frame are distributed in sequence along the length direction of the truss and are all located at the bottom of the truss. A mechanical gripper is provided on the top of the truss, and the mechanical gripper is slidably connected to the truss, so that after the braided hose is assembled at the assembly station, it is transported to the inspection station along the conveying direction of the conveying platform for preliminary inspection, and then, under the action of the mechanical gripper, the qualified products are collected in the collection frame after passing the airtightness inspection station and the X-ray inspection station inspection in sequence. The whole process does not require human intervention, which is conducive to improving work efficiency. The conveying platform is provided with a number of limit members that are transmitted and evenly distributed along the conveying direction. The bottom of the limit member is connected to the conveying platform, and the braided hose is limited at the top of the limit member, which is conducive to ensuring the braided hose during conveying. To ensure the position stability during the feeding process, a rectangular metal frame is provided on the limit piece, and the limit piece is located in the metal frame. The metal frame is rotatably connected to the side wall of the limit piece, and the side wall of the conveying platform is provided with a mounting groove corresponding to the detection station, and a plurality of cylinders corresponding to a plurality of braided hoses on the detection station can be detachably installed in the mounting groove, and a magnet is fixed on the output end of the cylinder, and one end of the metal frame is located directly below the braided hose, and the mechanical gripper is located above the braided hose, and the other end of the metal frame corresponds to the corresponding magnet up and down. When the detection station detects unqualified products, the corresponding cylinder drives the magnet to rise and approach the metal frame, so that the metal frame rotates instantly and pries the corresponding braided hose, so that the unqualified products fall into the corresponding area outside the conveying platform, realizing automatic screening and separation of unqualified products, which is convenient and fast. The braided hose is transported through a conveyor table, first passed through an assembly station for joint assembly, then passed through an inspection station for preliminary inspection to see if the joint is in place, and then passed through an air tightness inspection station and an X-ray inspection station in turn to inspect the air tightness of the braided hose and further inspect whether the joint is in place, thereby achieving the purpose of ensuring product quality.

[0009] Preferably, the limiting member includes two limiting protrusions, one of which is close to the mounting groove and located inside the metal frame, and the other is away from the mounting groove and located outside the metal frame. The bottom of the limiting protrusion is connected to the conveyor platform, and the top of the limiting protrusion is provided with a limiting groove 1. One end of the braided hose is located in the limiting groove 1 of one of the limiting protrusions, and the other end of the braided hose is located in the limiting groove 1 of the other limiting protrusion. The metal frame is rotatably connected to the limiting protrusion close to the mounting groove. This design allows one end of the metal frame to be placed between the two limiting protrusions. When the other end of the metal frame is attracted by the magnet and sinks, according to the principle of leverage, the end of the metal frame placed between the two limiting protrusions instantly tilts upward and acts on the braided hose, causing the braided hose to tilt and fall from the side of the conveyor platform, thereby realizing automatic screening and separation of unqualified products, which is convenient and quick.

[0010] Preferably, a contact block is provided at one end of the metal frame, located directly below the braided hose. The bottom of the contact block is fixedly connected to the metal frame, while the top of the contact block contacts the corresponding braided hose. This design ensures that the metal frame and the braided hose are not aligned, facilitating gripping by the mechanical gripper. Furthermore, the metal frame's contact with the braided hose via the contact block allows the braided hose to experience a greater inclination and force when the metal frame rotates, thereby improving the automatic screening and separation of unqualified products.

[0011] Preferably, the air tightness test table and the X-ray test table are fixed with two limit plates that are parallel to the sliding direction of the mechanical gripper, and the limit plates are provided with a number of limit grooves 2 that match the braided hose. One end of the braided hose is located in the limit groove 2 on one of the limit plates, and the other end of the braided hose is located in the limit groove 2 on the other limit plate, which is beneficial to the limitation of the braided hose and the grasping of the mechanical gripper. The air tightness test table and the X-ray test table are both provided with a number of rectangular grooves that correspond one to one to the braided hose, and the rectangular grooves are located in the limit grooves. Between the two limit plates and perpendicular to the limit plates, an elastic sheet is provided in the rectangular groove, one end of the elastic sheet is fixedly connected to one end of the rectangular groove, and the other end of the rectangular groove is detachably installed with cylinder 2, and a slider is provided on the output end of cylinder 2. The slider is slidably connected to the bottom of the rectangular groove along the length direction of the rectangular groove under the drive of cylinder 2, and cylinder 3 is detachably installed on the slider, and the telescopic direction of cylinder 3 is perpendicular to the telescopic direction of cylinder 2, and the output end of cylinder 3 is connected with a toggle block in contact with the other end of the elastic sheet. The air tightness test bench is used to test the air tightness of braided hoses. Braided hoses are generally made of rubber, and the material used for the joints is generally metal. Therefore, when X-rays reach the strength of penetrating metal, the rubber is almost unrecognizable. Therefore, the use of an X-ray test bench can detect whether the joint is completely inserted into the braided hose, further improving the detection accuracy of whether the joint is installed in place. One end of the elastic sheet is fixed, and the other end can bend and bounce towards the braided hose under the action of the toggle block, causing the braided hose to be instantly thrown up and fall into the corresponding collection area. The structure is simple.

[0012] Preferably, one side of the toggle block is proximal to the braided hose, while the other side of the toggle block is distal to the braided hose. The side of the toggle block distal to the braided hose is provided with an inclined guide surface that contacts the elastic sheet. The inclined guide surface is provided with a plurality of evenly distributed ridges that are parallel to the width of the elastic sheet. The design of the ridges increases the resistance to the toggle block disengaging from the inclined guide surface, thereby increasing the curvature of the elastic sheet and thereby further enhancing the elastic force of the elastic sheet, thereby improving the automatic screening and separation of unqualified products.

[0013] Preferably, the assembly station is provided with two assembly parts and two positioning parts corresponding to the assembly parts one by one, respectively. The two assembly parts are located on both sides of the conveying platform, and the assembly parts include a propulsion cylinder, which is detachably connected to the side wall of the conveying platform. A propulsion block is provided on the output end of the propulsion cylinder, and the propulsion block is slidably connected to the conveying platform relative to the end of the braided hose under the drive of the propulsion cylinder. A plurality of clamps corresponding to a plurality of braided hoses on the assembly station are detachably installed on the propulsion block, and a connector matching the end of the braided hose is detachably installed in the clamp. The positioning part includes a plurality of clamps corresponding to a plurality of braided hoses on the assembly station. The support frame is overhead and mounted on a conveying platform. The bottom of the support frame is fixedly connected to the conveying platform. The propulsion block is located inside the support frame. A driving cylinder is detachably mounted on the top of the support frame. A positioning plate is provided on the output end of the driving cylinder. The top of the positioning plate is connected to the output end of the driving cylinder. The bottom of the positioning plate is provided with a positioning block equal in number to the clamp on the corresponding propulsion block. The top of the positioning block is fixedly connected to the positioning plate. The bottom of the positioning block is provided with a positioning groove corresponding to the first limiting groove. The positioning groove matches the braided hose. The braided hose is located between the positioning groove and the first limiting groove. During assembly, the driving cylinder drives the positioning plate downward, causing the positioning block to gradually approach the limiting protrusion until the positioning block contacts the limiting protrusion. At this time, the braided hose is located between the positioning groove and the first limiting groove and is clamped, which is conducive to the assembly of the end of the braided hose and the connector. Then, the propulsion cylinder pushes the propulsion block gradually toward the end of the braided hose, so that the connector is assembled into the end of the braided hose and is clamped. This is convenient and fast, and helps to improve work efficiency.

[0014] Preferably, cushioning pads are secured to the bottom of the positioning block and its positioning groove, and to the top of the limiting protrusion and its limiting groove 1. This design allows the positioning block and limiting protrusion to press against each other, while also increasing the friction between the braided hose and the positioning groove and limiting groove 1, further enhancing the braided hose's positioning effectiveness.

[0015] Preferably, both sides of the detection station are provided with several groups of photoelectric sensors corresponding to several braided hose ends on the station, and each group of photoelectric sensors has two photoelectric sensors, one of which is close to the end of the braided hose, and the other is far away from the end of the braided hose. The distance between the two photoelectric sensors is less than the length of the connector, which is beneficial in normal conditions. Of the two photoelectric sensors in the same group, one is close to the end of the braided hose and the other is not sensed, indicating that the connector has been installed in place. Under normal conditions, the braided hose may deviate from its placement position, which may easily cause the connector at one end of the braided hose to be improperly installed. At the same time, since a limiting step surface is often provided on the connector, the braided tube will not be over-installed to the connector at the other end. Therefore, when the two photoelectric sensors corresponding to one end of the braided hose are both sensed, it indicates that the connector on the braided hose is not installed in place, which is beneficial for rapid and sensitive detection of unqualified products.

[0016] The present invention also provides a detection method for a braided hose automatic assembly detection device, comprising the following steps:

[0017] Step 1: Place several braided hoses on the limiting piece in order;

[0018] Step 2: The conveyor platform transports the braided hose to the assembly station and assembles the joints at both ends;

[0019] Step 3: After assembly is completed, the conveyor continues to work and transports the assembled braided hose to the inspection station to conduct a preliminary inspection on whether the joint is installed in place, and automatically rejects the unqualified products;

[0020] Step 4: The robot grabs the qualified products retained at the inspection station and transports them to the airtightness inspection table to test the airtightness of the products. The unqualified products are automatically rejected.

[0021] Step 5: The robot grabs the qualified products retained on the air tightness test table and transports them to the X-ray inspection table to conduct further inspection on whether the joints are installed in place, and automatically removes the unqualified products. At the same time, the robot transports the qualified products retained on the X-ray inspection table to the aggregate frame.

[0022] The braided hose is transported through a conveyor table, first passes through an assembly station for joint assembly, then passes through an inspection station for preliminary inspection to see if the joint is in place, and then passes through an air tightness inspection station and an X-ray inspection station in turn to inspect the air tightness of the braided hose and further inspect whether the joint is in place. Unqualified products are automatically screened and separated during each inspection process, thus ensuring product quality and improving work efficiency.

[0023] Preferably, in step three, the specific operation steps of the detection station detection are as follows:

[0024] Step A1: The conveyor platform conveys the assembled braided hose to the inspection station until both ends of the braided hose are aligned with the corresponding photoelectric sensors;

[0025] Step A2: When both of the two photoelectric sensors in the same group are sensed, the system transmits a signal to cylinder 1 corresponding to the photoelectric sensors in the group;

[0026] In step A3, the air cylinder drives the magnet upward, gradually bringing it closer to the metal frame and generating a magnetic attraction. This magnetic attraction instantly causes the metal frame to rotate, causing one end of the metal frame to rise and act on the corresponding braided hose. Simultaneously, the other end of the metal frame sinks, and the braided hose, pried by the metal frame, falls from the side of the conveyor platform into the corresponding area. This structural principle is simple and helps improve the automatic screening and separation of unqualified products.

[0027] Preferably, in steps 4 and 5, the specific steps for automatically rejecting unqualified products are as follows:

[0028] Step S1: When the product fails the test, the system receives the signal and controls the cylinder 3 in the corresponding rectangular slot to work;

[0029] In step S2, cylinder three drives the toggle block away from the braided hose, gradually bending the elastic sheet until it releases the toggle block. Cylinder two then drives the slider away from the elastic sheet, which, through its elastic force, acts on the braided hose, throwing it into the appropriate area. Once the elastic sheet returns to its original position, cylinder two again drives the slider toward the elastic sheet, bringing the toggle block into contact with it. This simple structural principle improves the automated screening and separation of unqualified products.

[0030] The beneficial effects of the present invention are: no human intervention is required, which is conducive to improving work efficiency; it is conducive to ensuring the position stability of the braided hose during the transportation process; it realizes automatic screening and separation of unqualified products, which is convenient and fast; product quality can be guaranteed; it is conducive to improving the automatic screening and separation effect of unqualified products; and it is conducive to quickly and sensitively detecting unqualified products.

[0045] like Figures 2-4As shown, the assembly station 7 is provided with two assembly parts 26 and two positioning parts 27 corresponding to the assembly parts 26 respectively. The two assembly parts 26 are respectively located on both sides of the conveying platform 2. The assembly part 26 includes a propulsion cylinder 28, which is detachably connected to the side wall of the conveying platform 2. A propulsion block 29 is provided on the output end of the propulsion cylinder 28. The propulsion block 29 is slidably connected to the conveying platform 2 relative to the end of the braided hose 1 under the drive of the propulsion cylinder 28.

Buffer pads are fixed to the bottom of the positioning block 35 and in its positioning slot 36, and to the top of the limiting protrusion 15 and in its limiting slot 16.

[0046] like Figure 3 As shown, both sides of the detection station 8 are provided with several groups of photoelectric sensors 31 corresponding to the ends of several braided hoses 1 on the station, and the number of photoelectric sensors 31 in each group is two, one of which is close to the end of the braided hose 1, and the other photoelectric sensor 31 is far away from the end of the braided hose 1, and the distance between the two photoelectric sensors 31 is less than the length of the joint.

[0047] The present invention also provides a detection method for a braided hose automatic assembly detection device, comprising the following steps:

[0048] Step 1: Place several braided hoses 1 on the limiting member 10 in order;

[0049] Step 2: The conveyor platform 2 conveys the braided hose 1 to the assembly station 7 and assembles the joints at both ends;

[0050] Step 3: After the assembly is completed, the conveyor 2 continues to work and conveys the assembled braided hose 1 to the inspection station 8 to conduct a preliminary inspection on whether the joint is installed in place, and automatically rejects the unqualified products;

[0051] Step 4: The robot grabs the qualified products retained on the inspection station 8 and transports them to the airtightness inspection table 3 to test the airtightness of the products, and automatically removes the unqualified products;

[0052] In step five, the robot grabs the qualified products retained on the air tightness inspection table 3 and transports them to the X-ray inspection table 4 to conduct further inspection on whether the joints are installed in place, and automatically removes the unqualified products. At the same time, the robot transports the qualified products retained on the X-ray inspection table 4 to the aggregate frame 5.

[0053] In step 3, the specific operation steps of the detection station 8 are as follows:

[0054] Step A1: The conveyor platform 2 conveys the assembled braided hose 1 to the inspection station 8 until both ends of the braided hose 1 correspond to the corresponding photoelectric sensors 31;

[0055] Step A2: When both of the two photoelectric sensors 31 in the same group are sensed, the system transmits the signal to the cylinder 13 corresponding to the photoelectric sensors 31 in the group;

[0056] In step A3, the cylinder 13 drives the magnet 14 to rise, so that the magnet 14 gradually approaches the metal frame 11 and generates a magnetic attraction. The metal frame 11 rotates instantly under the action of the magnetic attraction, so that one end of the metal frame 11 rises and acts on the corresponding braided hose 1. At the same time, the other end of the metal frame 11 sinks, and the braided hose 1 falls from the side of the conveyor platform 2 to the corresponding area under the prying of the metal frame 11.

[0057] In steps 4 and 5, the specific steps for automatically rejecting unqualified products are as follows:

[0058] Step S1, when the product fails the test, the system receives the signal and controls the cylinder 3 23 in the corresponding rectangular slot 19 to work;

[0059] In step S2, cylinder three 23 drives the toggle block 24 to move away from the braided hose 1, causing the elastic sheet 20 to gradually bend and deform until the elastic sheet 20 is separated from the toggle block 24. Cylinder two 21 drives the slider 22 away from the elastic sheet 20. The elastic sheet 20 acts on the braided hose 1 through elastic force, causing the braided hose 1 to be thrown into the corresponding area. When the elastic sheet 20 is reset, cylinder two 21 drives the slider 22 again close to the elastic sheet 20, causing the toggle block 24 to contact the elastic sheet 20.

[0060] When the braided hose 1 is transported to the assembly station 7 for assembly, the driving cylinder 33 drives the positioning plate 34 downward, so that the positioning block 35 gradually approaches the limiting protrusion 15 until the positioning block 35 contacts the limiting protrusion 15. At this time, the braided hose 1 is located between the positioning groove 36 and the limiting groove 16 and is clamped, which is conducive to the assembly of the end of the braided hose 1 and the connector; then, the thrust cylinder 28 pushes the thrust block 29 gradually to the end of the braided hose 1, so that the connector is assembled into the end of the braided hose 1 and is clamped. After assembly is completed, it is transported to the inspection station 8 for inspection.

[0061] Under normal conditions, among the two photoelectric sensors 31 in the same group, when one photoelectric sensor 31 close to the end of the braided hose 1 is sensed and the other photoelectric sensor 31 is not sensed, it indicates that the connector has been installed in place; under normal conditions, the braided hose 1 may deviate from its placement position, which may easily cause the connector at one end of the braided hose 1 to be improperly installed. At the same time, since a limiting step surface is often provided on the connector, there will be no over-installation of the braided tube to the connector at the other end. Therefore, when both photoelectric sensors 31 corresponding to one end of the braided hose 1 are sensed, it indicates that the connector on the braided hose 1 is not properly installed, thereby facilitating the rapid and sensitive detection of unqualified products.

[0062] The air tightness test bench 3 is used to test the air tightness of the braided hose 1; the braided hose 1 is generally made of rubber, and the material used for the joint is generally metal. Therefore, when the X-ray reaches the strength of penetrating metal, the rubber is almost unrecognizable. Therefore, the X-ray test bench 4 can be used to detect whether the joint is completely inserted into the braided hose 1, further improving the detection accuracy of whether the joint is installed in place.
