DETAILED DESCRIPTION

[0020] In order to make the purpose, technical scheme and advantages of the application clearer, the application will be further described in detail below with reference to the drawings. The terms used in the embodiment part of the application are only used to explain the specific embodiments of the application, and are not intended to limit the application.

[0021] In the scissor production process, the welding of the blade and the handle is one of the important processes. In order to ensure the quality of the product, the joint position of the blade and the handle needs to be welded in a whole circle, which results in that the single-sided welded scissor needs to be turned over and welded again after being turned over, and the welded scissor needs to be fixed again after being turned over, which is low in efficiency and the welding robot needs to wait during the turning-over process.

[0022] Based on the above technical problems, the embodiment of the present application provides a scissor handle welding device which can be turned over.

[0023] As shown in Figure 1 The present application comprises a rack 1 and at least one set of rotary welding assembly arranged on the rack 1. Each set of rotary welding assembly comprises a tooling plate 4 and a rotary driving device. The rotary driving device is mounted on the rack 1, and the tooling plate 4 is rotatably connected to the rack 1 through coaxially arranged shafts 5 at both ends of the tooling plate 4. At least one end of the shaft 5 is connected to the rotary driving device, so that the tooling plate 4 can be rotated under the driving of the rotary driving device. A set of positioning devices for fixing the handle 3 and the blade 2 on the tooling plate 4 is arranged on the tooling plate 4. Welding holes 9 which penetrate through the back of the tooling plate 4 from top to bottom are arranged on the tooling plate 4 at positions corresponding to the joint positions 31 of the handle 3 and the blade 2 fixed on the tooling plate 4, so as to facilitate welding of the joint positions 31 from the back.

[0024] Before the device is operated, the tooling plate 4 is reset, i.e. the face with the positioning devices is upward, the handle 3 and the blade 2 are placed in the positioning devices, and the welding robot welds the joint positions 31 of the handle 3 and the blade 2. After the welding is completed, the rotary driving device is started to rotate the tooling plate 4 by 180°, so that the tooling plate 4 is turned over to the back of the tooling plate 4. The welding robot passes through the welding holes 9 to complete the welding of the back of the joint positions 31 of the handle 3 and the blade 2. In this way, the handle 3 and the blade 2 are fixed once and welded on both sides, so that the whole circle welding of the handle 3 and the blade 2 is realized.

[0025] In some embodiments, the number of positioning devices is more than two, and each set of positioning devices is arranged in sequence along the axial direction of the parallel shafts 5. Each welding hole 9 corresponding to the joint positions 31 of the handle 3 and the blade 2 fixed on the tooling plate 4 is sequentially communicated to form a welding groove hole.

[0026] The positioning devices in the device of the present application are as shown in Figure 1The shown includes handle fixed block and blade fixed block, the handle fixed block is the sleeve embedded handle fixer 71 for embedding the handle 3 according to the handle contour customization, the blade fixed block includes the pin 73 for being placed in the rivet hole 21 of the blade 2 and the magnet 72 for adsorbing the blade 2. For the convenience of disassembly, in some embodiments, the handle fixer 71, the magnet 72, the pin 73 in the positioning device can be fixed in a detachable manner, such as screw installation and the like. But each time disassembly and installation need to adjust the relative position between the handle fixer 71, the magnet 72, the pin 73 according to the scissors model, so that the junction 31 of the handle 3 and the blade 2 can be accurately connected. In order to simplify the process, in some embodiments, the handle fixer 71, the magnet 72, the pin 73 in each set of positioning device are connected as a whole positioning device assembly, which is installed on the tool plate 4, thereby reducing the time of adjusting the connection position, and facilitating the installation of multiple different models of scissors positioning devices on the same tool plate for welding. In practice, batch welding of the same model of scissors is often required, and if each scissors positioning device is installed separately, the workload is large, in order to realize batch positioning device installation, in some embodiments, multiple scissors positioning devices are connected as a whole to form a positioning device array, which is installed on the tool plate 4, thereby reducing the installation workload and improving the installation efficiency; in some embodiments, for different models of scissors, which may only have different handles or only different blades, multiple blade positioning devices can be connected together, or multiple handle positioning devices can be connected together, and then replaced as a whole on the tool plate 4 as needed.

[0027] In order to increase the fixation of the blade 2, in some embodiments, a sliding groove 8 extending along the axial direction of the parallel shaft 5 is provided on the tool plate 4, and one or more sliding bolt magnets 81 capable of sliding relative to the sliding groove 8 and being locked and fixed in the sliding position are arranged in the groove, and the positioning device positions the blade 2 by magnetically adsorbing the blade.

[0028] In some embodiments of the above design, the rotating drive device includes a servo motor 61, a speed reducer 62 and a shaft coupling 63, wherein the servo motor 61 and the speed reducer 62 are installed on the shaft base 11 by a motor support, the servo motor 61 is connected to the speed reducer 62, and the speed reducer 62 is connected to the shaft 5 through the shaft coupling 63, so that the tool plate 4 can be rotated by starting the servo motor 61. In some embodiments, the rotating drive device is in the mode of driving the shaft by the handle to rotate the tool plate 4.

[0029] In practice, when the tool plate 4 is loaded, unloaded and turned over, the welding robot can only wait, in order to improve the utilization rate of the welding robot, in some embodiments, a mode such as Figure 3The two groups and more than two groups of the rotating welding assembly of the design form an array of devices, when the automatic welding robot welds the front of the first set of devices, the second set of devices can be loaded at the same time, when the front welding of the first set of devices is completed, the automatic welding robot immediately starts to weld the front of the second set of devices, at this time the first set of devices is turned over by 180 degrees under the guidance of the rotating drive device, when the welding of the second set of devices is completed, the automatic welding robot returns to the first set of devices to weld the back joint 31 of the first set of devices, at this time the second set of devices is turned over by 180 degrees under the guidance of the rotating device, when the back welding of the first set of devices is completed, the automatic welding robot directly starts to weld the back of the second set of devices, at this time the first set of devices can be unloaded and reloaded, so as to improve the utilization rate of the automatic welding robot and the production efficiency. In implementation, the number of arrays can be adjusted according to the actual welding time, loading and unloading time, such as three sets, four sets or more rotating welding assemblies of the design form an array.
