[0097] Automatic tool changing system 1
[0098] Figure 1 An automatic tool changing system 1 according to an embodiment of the present invention is schematically shown.
[0099] like Figure 1As shown, the automatic tool changing system 1 replaces the prop 3000 in the following manner, that is, the indexing rotary motor 4000, the rotary indexing table 2000 and the plurality of props 3000 are sequentially located on the upper surface of the bracket 5000, and according to the work content, one of the plurality of props 3000 is fastened to the tool holder 1200 at the end of the multi-joint robot located outside.
[0100] Preferably, the automatic tool changing (Auto Tool Changing) system of one embodiment of the utility model may include: an indexing rotary motor 4000; a rotary indexing table 2000, which can be rotated by means of the indexing rotary motor 4000, and the upper surface of which is provided with a plurality of cylinder-type clamping members 2500 that use air pressure to perform clamping actions; a plurality of props 3000, each of which is fixed in position on the rotary indexing table 2000 by one of the plurality of cylinder-type clamping members 2500 in a manner having a different z-coordinate value, each including a tool chuck unit located at the upper end and formed with a pneumatic pipeline connection unit and a tool chuck unit located at the lower side of the tool chuck unit and A clamping chuck unit capable of loading and unloading by means of the cylinder-type clamping part 2500; and a tool clamp 1200, comprising: a clamping cylinder unit 1230, located on the lower side of the multi-joint robot 1000; and a clamping unit 1240, located on the lower side of the clamping cylinder unit 1230, fastened to the tool chuck unit of the corresponding prop 3000 by means of the force transmitted by the clamping cylinder unit 1230, comprising a four-way pneumatic pipeline port, and utilizing the pneumatic pressure supplied through the four-way pneumatic pipeline port to control the movement of one of the plurality of props 3000.
[0101] The plurality of props 3000 include a vacuum clamp 3100 , a pneumatic driver 3200 , a grinder 3300 , a two-jaw clamp 3400 , and a three-jaw flexible clamp 3500 .
[0102] The vacuum clamp 3100 , the two-jaw clamp 3400 , and the three-jaw flexible clamp 3500 perform a vacuum action, the pneumatic driver 3200 , the grinder 3300 , and the three-jaw flexible clamp 3500 perform a rotation action, and the two-jaw clamp 3400 and the three-jaw flexible clamp 3500 perform a clamping action.
[0103] That is, unlike the existing automatic tool changing system 1 which can only perform a single motion of cutting by means of a rotation action, the automatic tool changing system 1 according to one embodiment of the present invention can perform rotation, vacuum and clamping actions in a single system.
[0104] Preferably, the present invention can provide an automatic tool changing system 1 that can use a single multi-jointed arm to use a variety of props that can perform various forms of actions for disassembling waste displays.
[0105] If the automatic tool changing system 1 of one embodiment of the utility model uses one of the plurality of props 3000, the tool holder 1200 is moved to the preset x-coordinate and y-coordinate on the side of the rotary indexing table 2000 through a preset entry (in) path by means of an external multi-joint robot without being affected by the type of the prop 3000. The rotary indexing table 2000 is driven to rotate by the indexing rotary motor 4000 so that the corresponding prop 3000 moves to the position corresponding to the preset x-coordinate and y-coordinate. Thereafter, the tool holder 1200 moves up and down according to the preset z-coordinate of the corresponding prop 3000, and the clamping unit 1240 and the plurality of props 3000 can be fastened together by means of the action of the clamping cylinder unit 1230.
[0106] When the existing automatic tool changing system 1 uses multiple props 3000 to execute a process, additional settings need to be made according to each prop 3000. The configuration described above is different from this. No matter which prop 3000 is used to execute which process, only the z-axis value is used variably to achieve more stable and accurate operation.
[0107] That is, due to the above configuration, when the prop 3000 is selected, the rotary indexing table 2000 is rotated to fix the position of the fastening connection with the multi-joint robot arm 1000, and only the fastening connection height (z coordinate) of each prop 3000 is set differently, thereby greatly reducing the repetitive precision error caused by the robot transfer control.
[0108] Figure 2 A tool holder 1200 according to an embodiment of the present invention is schematically shown.
[0109] The tool holder 1200 corresponds to the following component, which is located at the end of the external multi-joint robot and allows the multi-joint robot arm 1000 and one of the plurality of tools 3000 on the rotary indexing table 2000 to be fastened together.

[0111] Preferably, the tool holder 1200 may include: a connecting portion, located on the lower side of the multi-joint robot arm 1000; a placement plate (1220), located on the lower side of the connecting portion; a clamp cylinder unit 1230, located on the lower side of the placement plate (1220), driving the action of grasping or placing the plurality of props 3000; and a clamping unit 1240, the upper side of which is fixed to the clamp cylinder unit 1230 and has four air pressure line ports formed on the side.
[0112] In the described configuration, the four-way air pressure pipeline ports may include a blowing pipeline port 1242 for applying air pressure from the outside direction to the inside direction, a suction pipeline port 1243 for applying air pressure from the inside direction to the outside direction, a clamping part opening pipeline port 1244 for applying air pressure from the outside direction to the inside direction, and a clamping part closing pipeline port 1245 for applying air pressure from the outside direction to the inside direction.
[0113] The blowing line port 1242, the suction line port 1243, the clamping piece opening line port 1244 and the clamping piece closing line port 1245 are connected to the tool chuck unit and apply air pressure to the plurality of props 3000 sides so that the prop 3000 body can perform rotation, vacuum and clamping actions.
[0114] That is, the clamping unit 1240 in the tool holder 1200 is fastened to the prop 3000 by means of the force from the clamping cylinder unit 1230, and the movement of the fastened prop 3000 is controlled by the air pressure supplied through the four-way air pressure line port located in the clamping unit 1240, so that a variety of props that perform various types of actions can be used in a single system.
[0115] On the other hand, the placement plate (1220) of one embodiment of the utility model may include: a plate body (1221) having an overall rectangular shape; a visual component placement portion 1222 formed through one end of the plate body (1221), on which a camera for identifying the display of the disassembled object is placed; and a laser component placement portion 1223 formed through the other end of the plate body (1221), on which a laser component for operation is placed.
[0116] Preferably, a camera independent of a camera for recognizing the display of the dismantling object is disposed in the visual component disposing portion 1222 , and the camera recognizes the display of the dismantling object from the perspective of the multi-joint robot arm 1000 .
[0117] Preferably, the laser component placement portion 1223 is provided with a laser component that can perform cutting actions, engraving actions, etc. during display disassembly operations.
[0118] Figure 3The schematic diagram shows a state where a tool holder 1200 and a tool 3000 according to an embodiment of the present invention are combined.
[0119] The tool chuck unit of one embodiment of the utility model comprises: a front frame, a through hole is formed in the center; a rear frame is separated from the front frame at a preset distance, a through hole is formed in the center; and a pair of side frames are located between the front frame and the rear frame, and have an inclined protrusion formed by the outer side surface being inclined from the upper side to the center side; the clamping unit 1240 may include: a pair of clamping body 1241, having a clamping inclined groove 1241-1 formed by bending the lower end portion inward and having an overall shape; and, the tool chuck air pressure line port, located in the pair of clamp body 1241 and can be connected to each of the four-way air pressure line ports of the six-axis multi-articular robot.
[0120] When the tool holder 1200 is combined with one of the plurality of tools, the tool holder 1200 can be combined in a form in which the inclined groove 1241-1 formed on the holder body 1241 of the clamping unit 1240 and the inclined protrusion formed on the side frame of the tool chuck unit are engaged with each other.
[0121] For example, Figure 3 As shown, when the tool holder 1200 and the vacuum clamp 3100 are combined, the inclined groove portion 1241-1 of the holder formed on the holder body 1241 of the clamping unit 1240 and the first inclined protrusion 3113-1 formed on the first side frame 3113 of the first tool chuck unit 3110 of the vacuum clamp 3100 can be combined in a mutually meshing form.
[0122] Preferably, when the tool holder 1200 is combined with one of the plurality of tools, the pair of holder bodies 1241 are combined with the pair of side frames on the outside so that the inclined protrusion and the holder inclined groove 1241 - 1 can engage with each other.
[0123] At this time, preferably, the inclined protrusion and the holder inclined groove portion 1241 - 1 have shapes in which the inclined surfaces thereof correspond to each other.
[0124] The structure as described above is a structure that can respond to errors caused by repetitive precision errors caused by robot transfer control when the automatic tool changing system 1 replaces the prop 3000. It is a structure that can prevent damage to the prop 3000 and the tool holder 1200 if the position of the prop 3000 is within a preset error range.
[0125] That is, as described above, when the tool holder 1200 and the tool 3000 are fastened together, the inclined surfaces are in contact with each other, so as long as they are kept within an appropriate tolerance, they can be clamped without damaging the structure.
[0126] Moreover, preferably, the tool holder 1200 sets the force transmitted by the holder cylinder unit 1230 to the clamping unit 1240 to be lower than the fixed torque of the multi-joint robot 1000 and the fixed torque of the rotary indexing table 2000 .
[0127] That is, as described above, the air pressure of the clamp cylinder unit 1230 is set to be lower than the fixing torque of the multi-joint robot 1000 and the fixing torque of the rotary indexing table 2000 to prevent the fastening parts of the tool clamp 1200 and the tool 3000 from being damaged during fastening.
