Description

Technical Field

[0002] At present, the patent document with application number: CN201921059082.1 records the technical solution of the pocket patching machine. It can be seen that the pocket patching machine, a sewing device, involves a variety of mechanical arm mechanisms, such as the folding mechanical arm in the pocket fabric folding mechanism and the mechanical arm for feeding and sewing the fabric in the fabric pressing mechanism. These mechanical arms with different functions are equipped with some small pneumatic components, such as small cylinders, which realize some actions by connecting to an air source (air pump). In order to ensure accurate and reliable movement, sensors (travel switches) for sensing stroke are also set on the cylinder. These stroke sensors are used to feedback electrical signals, so they are transmitted through wires. It can be seen that these devices involve wires for transmitting electrical signals and air pipes for controlling the movement of the cylinder. In order to facilitate the interchange of molds, different sewing requirements require different robot arm molds to adapt. Therefore, different robot arm heads need to be quickly assembled and interchanged, and these structures need to be considered. If these cylinders are directly connected to the air pump through hoses, and the sensors are directly connected to the controller through wires, then the lines and pipelines will be very messy and inconvenient to disassemble and assemble, because the interference of the mechanical structure is also involved during disassembly and assembly, so the spatial position of the mechanical structure must be fully considered.

It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0018] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present application. The illustrations only show the components related to the present application rather than being drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the type, quantity and proportion of each component can be changed at will, and the component layout type may also be more complicated.

[0019] The specific implementation methods of the present application will be further described below in conjunction with the accompanying drawings. Example

[0020] The embodiment of the present application discloses a highly efficient disassembly and assembly mechanical arm mechanism on a sewing device, including a folding mechanical arm 1 and a material picking and sewing feeding mechanical arm 2. Both the folding mechanical arm 1 and the material picking and sewing feeding mechanical arm 2 include multiple cylinders, multiple sensors 3, and a mounting seat 4. The cylinder needs to be connected to an air pipe to achieve driving, and the air pipe is used to provide air source power. Each cylinder is connected to the mounting seat 4 through a hose. In specific practical applications, there will be joints at both ends of the hose to achieve fixed and sealed connections at the ends of the hose. Each sensor 3 is connected to the mounting seat 4 through a wire, and the mounting seat 4 is provided with an air circuit integrated connection seat 5 and a circuit integrated connection seat 6. The sensor 3 here can be a travel switch sensor 3 (Hall sensor 3) on the cylinder, etc. The air circuit integrated connection seat 5 and the circuit integrated connection seat 6 here are a general term, which can be a separate component or a structure integrated with the connection seat.

[0021] refer to Figure 1 , 2 As shown in FIGS. 3 and 4, the folding mechanical arm 1 also includes a bracket 9, an arm 101, a line integrated plug 102, and a plug socket 103. The arm 101 is fixed to the mounting base 4 by four fine-tuning bolts 115, so that the mounting base 4 can fine-tune the installation distance with the arm 101. The line integrated plug 102 is referred to Figure 6 As shown, it can complete the docking work of the line, and the disassembly and assembly are very convenient. The line integrated plug 102 is docked on the plug seat 103.

[0022] exist Figure 1 and Figure 4 As can be seen in the figure, the inner side of the bracket 9 is fixed with the circuit integrated connection seat 6, and the outer side is fixed with the gas circuit integrated connection seat 5. The circuit integrated connection seat 6 has a circuit integrated plug 102. The mounting seat 4 is provided with a fixing position for fixing the bracket 9 (i.e., the mounting position of the quick-install bolt 7). The mounting seat 4 is provided with a gas path that docks with the gas circuit integrated connection seat 5. The mounting seat 4 is provided with a plug seat 103 that docks with the circuit integrated plug 102 in the circuit integrated connection seat 6.

[0023] Firstly, in order to facilitate the disassembly and assembly of the air circuit hose and improve the integration, the other end of the hose (air pipe) connected to the cylinder in this scheme can be connected to the entrance of the side air duct 117 of the mounting seat 4. The mounting seat 4 is provided with an air duct 117, and the air duct 117 includes a vertical portion 118 and a horizontal portion 119. The vertical portion 118 and the horizontal portion 119 are connected, and the upper end of the vertical portion 118 is connected to the air circuit integrated connection seat 5, and the port of the horizontal portion 119 is connected to the air pipe interface 106 of the cylinder body 108 through an air pipe. Figure 5 The dotted line in the figure indicates another air passage 117, which indicates that multiple air passages 117 can be designed by using vertical portions 118 and horizontal portions 119 of different lengths, so as to realize the switching of the air passage. Therefore, the air passage is switched through such a structure, and it is also very convenient to disassemble and assemble.

[0024] refer to Figure 4 It can be seen that only four quick-release bolts 7 need to be removed to realize simultaneous disassembly of the gas circuit, circuit, and mechanical modular structure, or during assembly, the positioning pins 8 can be used to quickly realize automatic docking and assembly.

[0025] The front end of the arm 101 is fixedly connected to the model plate 104, and the cylinder is fixedly connected to the edge of the model plate 104, and the cylinder is a cloth folding cylinder 105. The bottom surface of the mounting seat 4 is also fixedly mounted with a cloth folding cylinder 105. The model plate 104 is in the shape of a pocket, and in order to realize the folding of the cloth into the pocket shape, the cloth folding cylinder 105 needs to be distributed on its edge.

[0026] Specifically, the cloth folding cylinder 105 includes an air pipe interface 106 (at Figure 1 A part is shown in the figure, in practice, each cylinder body 108 has a side), a sensor 3 card slot, a cylinder body 108, a telescopic rod 109, an adjustment seat 110 and a folding plate 111, the air pipe interface 106 is located on the side of the cylinder body 108, the sensor 3 card slot is located on the top of the cylinder body 108, the adjustment seat 110 is fixed to the end of the telescopic rod 109, and the folding plate 111 is fastened to the adjustment slot 112 of the adjustment seat 110. Here, the sensor 3 on the cylinder body 108 is a Hall sensor 3, which can sense the cylinder action stroke.

[0027] In order to facilitate the layout and traction of the wires, a through hole 113 is provided on the mounting seat 4 , so that the wires of the sensor 3 on the cylinder body 108 can be bundled together and pulled to the through hole 113 .

[0028] The arm 101 is provided with a long waist groove 114, in which a fine-tuning bolt 115 is assembled to adjust the fixed position of the arm 101 on the mounting seat 4. The arm 101 is also fixed with an adapter frame 116, and the adapter frame 116 is used for the wires of the sensor 3 to be transferred through the connector. The connector is arranged in this way, and further integrated disassembly and wiring of the wires can be realized, and the wires are not easy to be messy.

[0029] The model board 104 is integrated with a magnet 120 , the wires of the sensor 3 are connected to the plug socket 103 , the circuit integrated plug 102 is in the through slot of the circuit integrated connection socket 6 , and the circuit integrated plug 102 is used to dock with the plug socket 103 .

[0030] A sealing ring 41 is also provided for the gas circuit joint assembly to ensure reliable sealing and prevent air leakage. In this solution, after the four quick-release bolts 7 are disassembled, the circuit part, the gas circuit part and the mechanical modular structure can be disassembled at the same time. During installation, similarly, the assembly accuracy and reliability can be improved by positioning pins, so that the circuit joint, the gas circuit and the mechanical modular structure can be directly and simultaneously completed. Example

[0031] refer to Fig.10 As shown, the mechanical module can be replaced by removing four quick-release bolts 7. The operation is simple and efficient. The gas circuit and the circuit are separated together. When assembling, the gas circuit parts are connected to each other, and the circuit parts are connected through connectors (plug and socket components).

[0032] refer to Figure 7 and Figure 8 As shown, in this solution, the material feeding and seam feeding robot arm 2 also includes a main lifting mechanism. The main lifting mechanism includes a robot arm 202, a main slider 203, a main slide rail 204, a main lifting plate 205 and a main lifting cylinder 206. The main slider 203 and the main slide rail 204 serve as a linear movable pair.

[0033] At least two vertical and parallel main rails 204 are fixed on the mechanical arm 202, the main slider 203 is matched with the main rail 204 and fixed on the main lifting plate 205, the main lifting cylinder 206 is fixed on the mechanical arm 202 and drives the main lifting plate 205 to move up and down, and the main lifting plate 205 and the mounting seat 4 are fixedly connected by quick-release bolts 7. The main lifting plate 205 and the mounting seat 4 are both provided with a through slot 207 for the circuit integrated connection seat 6 to be installed.

[0034] In this solution, for the disassembly and assembly of the machine, the four quick-install bolts 7 on the mounting base 4 can be used to quickly separate it from the mechanical arm 202, so as to facilitate disassembly and assembly. At the same time, the separation of the air circuit and the circuit can also be achieved. On the mounting base 4, the air circuit integrated connection base 5 is directly designed as one body with the mounting base 4. Specifically, the air channel 117 is directly opened on the mounting base 4, and the cylinder can be directly connected to the entrance of the air channel 117 through a hose. As for the wire part, it is embedded in the through groove 207 through the line integrated plug 102.

[0035] This shows that quick disassembly and assembly can be achieved.

[0036] On the other hand, a cloth pressing outer frame 208 is fixed on the mounting seat 4, and a secondary lifting mechanism is installed in the middle of the mounting seat 4. The secondary lifting mechanism includes a secondary slider 210, a secondary slide rail 211, a secondary lifting plate 212 and a secondary lifting cylinder 213. The secondary slide rail 211 is fixed on the mounting seat 4, the secondary slider 210 is assembled on the secondary slide rail 211 and fixed on the secondary lifting plate 212, the secondary lifting cylinder 213 is fixed on the mounting seat 4 and drives the secondary lifting plate 212 to move up and down, and the air connecting end of the secondary lifting cylinder 213 is connected to the air circuit integrated connection seat 5 (line integrated plug 102) through a hose.

[0037] It can be seen that, for the cloth pressing outer frame 208, the lifting action is realized by the main lifting mechanism, and for the seam pressing mechanism, the lifting action is realized by the secondary lifting mechanism.

[0038] A seam pressing mechanism is fixed on the secondary lifting plate 212, and the seam pressing mechanism includes a support arm 215, a plurality of movable shafts 216, a movable block 217, a seam pressing plate 218, a seam changing cylinder 219, and a limit plate 220. The support arm 215 is provided with a plurality of first guide grooves 221, and the limit plate 220 is provided with a plurality of second guide grooves 222. Each movable shaft 216 is slidably assembled in the first guide groove 221 and the second guide groove 222. The limit plate 220 is driven by the seam changing cylinder 219 to move linearly on the support arm 215. The end of the movable shaft 216 is rotatably connected to the movable block 217, and the movable block 217 is fixedly connected to the seam pressing plate 218, and the two seam pressing plates 218 open and close. The second guide groove 222 is provided with a first guide path 223 and a second guide path.

[0039] As for the seam pressing mechanism, firstly, it has three seam pressing plates 218, the middle of the three seam pressing plates 218 can move forward and backward, and the remaining two are symmetrically distributed on both sides of the middle seam pressing plate 218 to realize the opening and closing action.

[0040] When the variable stitch cylinder 219 extends, the limit plate 220 is driven to move to the front end (with the cylinder axis pointing to the front), and the two seam pressing plates 218 are opened, thereby forming a gap between the outer frame 208 of the cloth pressing, so as to form a gap as shown in FIG. Fig. 9 Then, when the variable stitching cylinder 219 is retracted, the limit plate 220 is driven to retreat, and the two seam pressing plates 218 are closed, thereby forming a gap between the outer frame 208 of the cloth pressing plate 218 and the outer frame 208 of the cloth pressing plate 218. Fig. 9 The inner seam shown is used for pocket sewing. Compared with the previous double seam, the difference is as follows: Fig. 9 As shown, the width of the double suture on both sides, L1 is greater than L2, that is, the double suture is wider at the top and narrower at the bottom.

[0041] The above embodiments are only illustrative of the principles and effects of the present application, and are not intended to limit the present application. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application shall be included in the protection scope of the present application.
