This device supports contactless card swiping for payment, uses a microprocessor to control valve opening and closing for water management, has a built-in tiered water price calculation function, and is equipped with a dual display system of mechanical digits and an LCD screen. Laser welding is a high-energy-density laser beam as a heat source, melting materials and allowing them to cool and solidify to form a weld, thus achieving a highly efficient and precise welding method for joining workpieces.

[0003] The prior art Chinese utility model patent with application number CN202323087569.X relates to a shell welding device, including a base plate, a positioning fixture, a welding device, a clearance groove, a limiting block, a groove and an adjustment component, etc. It can drive the ultrasonic welding device to move toward the top cover and the base on the positioning fixture through the driving component, so as to realize ultrasonic welding of the top cover and the base, thereby facilitating welding production.

[0004] However, the above-mentioned device requires manual operation by the operator for loading the upper and lower parts of the shell to be welded, including the shell docking process, which increases the labor intensity of the operator. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a laser welding device for radio frequency card water meter housings. The device uses a feeding device to transport the housing to be welded and the housing to be welded. The material on the feeding device is adsorbed and fixed by a docking device and a suction device, and then moved and docked so that the laser equipment can perform welding. This reduces the labor intensity of the operators during the feeding process and improves the practicality of the device.

[0006] This utility model discloses a laser welding device for radio frequency card water meter housings; it includes a feeding device, a docking device, and a suction device. The docking device is installed on the feeding device, and the suction device is installed on the feeding device. The feeding device transports the housing to be welded and the housing to be welded. The docking device, in conjunction with the suction device, adsorbs and fixes the material on the feeding device and moves it for docking, so that the laser equipment can perform welding. This reduces the labor intensity of the operators during the feeding process and improves the practicality of the device.

[0007] Preferably, the feeding device includes a frame, conveyor rollers, a conveyor belt, a servo motor, vertical rubber sheets, and a laser welding assembly. Multiple sets of conveyor rollers are horizontally mounted on the left and right sides of the upper end face of the frame via supports. Two sets of conveyor belts are respectively fitted onto the multiple sets of conveyor rollers on both sides. A set of servo motors is mounted on each of the supports on both sides, and the output end of the servo motor is connected to the outermost set of conveyor rollers. Multiple sets of vertical rubber sheets are provided on the conveyor belts. After being cut, the vertical rubber sheets form the internal space shape of the housing. The laser welding assembly is mounted on the upper part of the frame via a robotic arm. The servo motors are activated to transmit power to the connected conveyor rollers, causing them to rotate. The rotating conveyor rollers, in conjunction with the conveyor belt, transport the housing and place it onto the cut vertical rubber sheets, thereby limiting the spatial position and orientation of the housing. This facilitates the subsequent suction device's adsorption and fixation of the housing, improving the practicality of the device.

[0008] Preferably, the docking device includes a lead screw, a geared motor, a first transverse platform, a second transverse platform, an electric cylinder, and a first limiting rod. The lead screw is mounted on the left side of the upper end face of the frame via a bracket. The first transverse platform is connected to the lead screw. A geared motor is mounted on the end of the bracket, and the output end of the geared motor is connected to the lead screw. The second transverse platform is located on the right side of the upper end face of the frame. Multiple sets of first limiting rods are horizontally fixed by the bracket and pass horizontally through the body of the second transverse platform. An electric cylinder is horizontally mounted on the right side of the bracket where the first limiting rods are located. The moving end of the electric cylinder is connected to the right end face of the second transverse platform. By controlling the extension of the electric cylinder, the second transverse platform is moved laterally. The multiple sets of first limiting rods provide support and movement limit for the second transverse platform. The geared motor is turned on to transmit power to the lead screw, causing the lead screw to rotate. The rotating lead screw causes the first transverse platform to move laterally, thereby cooperating with the suction device to remove the material from the feeding device and then perform joint docking of the material. This reduces the labor intensity of the operator and improves the practicality of the device.

[0009] Preferably, the suction device includes a rotating frame, a motor, a rotating arm, a suction cup, and a fan. A set of rotating arms is mounted on the upper surface of both the first and second transverse platforms via the rotating frame. A motor is mounted on the side of the rotating frame, and the output end of the motor is connected to the rotating shaft on the rotating frame. One end of the rotating arm is fitted onto the rotating shaft of the rotating frame. A suction cup and a fan are mounted on the rotating end of the rotating arm. The air inlet of the fan is connected to the suction cup, and the shape of the suction cup matches the shape of the shell being suctioned. The motor is turned on to transmit power to the rotating frame, causing the rotating arm to rotate, thereby rotating the suction cup to the opposite conveyor belt so that the suction cup covers the shell being transported on the opposite side. Then, the fan is turned on to extract the gas between the suction cup and the shell, thereby suctioning and fixing the shell. Afterward, the rotating arm is controlled to rotate to a vertical position, and the positions of the two sets of shells are adjusted in conjunction with the docking device to align and connect the two sets of shells, improving the practicality of the device.

[0010] Preferably, the device also includes a supporting electric cylinder, a wear-resistant head, and a stop block. The supporting electric cylinder is installed at an angle on the middle of the outer side of the feeding device bracket. The wear-resistant head is installed on the moving end of the supporting electric cylinder, and a stop block is provided on the middle of the outer side of the rotating arm. By controlling the extension of the supporting electric cylinder, the wear-resistant head is driven to push against the stop block on the rotating arm, thereby making the housings on the two sets of suction cups fit together more closely. In conjunction with turning off the fan, the influence of the suction cup adsorption force on the housing docking is reduced, the seam error is reduced, and the practicality of the device is improved.

[0011] Preferably, it also includes a second limiting light rod, which is horizontally installed on the upper surface of the frame and passes through the lower part of the first transverse platform; the second limiting light rod limits the transverse movement of the first transverse platform and provides auxiliary support, thereby reducing the vibration amplitude of the first transverse platform during transverse movement and improving the stability and practicality of the device.

[0012] Preferably, it also includes a limit switch. The limit switch is installed on the bracket where the first limit rod is located. The limit switch is located on the lateral movement path of the first lateral movement platform. The lateral movement position of the first lateral movement platform is limited by the limit switch to prevent the lateral movement position deviation of the first lateral movement platform from causing an increase in the docking gap, thereby improving the practicality of the device.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the feeding device transports the shell to be welded and the shell to be welded, and the docking device, in conjunction with the suction device, adsorbs and fixes the material on the feeding device and moves it to dock so that the laser equipment can perform welding. This reduces the labor intensity of the operators during the feeding process and improves the practicality of the device. Attached Figure Description
