Description

Technical Field

[0001] This utility model relates to the field of three-axis servo manipulator technology, and in particular to a three-axis servo manipulator for injection molding. Background Technology

[0002] Three-axis servo manipulators are precision devices widely used in industrial automation. They combine mechanical structure, servo control technology, and multi-degree-of-freedom motion capabilities. The manipulator has three independent degrees of freedom, usually including three linear axes. As a basic automation unit, three-axis servo manipulators play a key role in improving production efficiency (usually by 30%-50%) and product consistency. They are particularly suitable for manufacturing fields with a high degree of process standardization.

[0003] Currently, when a three-axis servo robot picks up plastic after injection molding, some of the plastic may not be fully cured, leaving some plastic on the clamping plate. When picking it up later, the plastic hardens, which may damage the surface of the plastic and reduce the contact area between the plastic and the clamping plate, resulting in less friction during picking. The picked-up plastic parts are likely to fall off during the picking process. Furthermore, when the operator is not at the workstation, the continuous operation of the robot may cause a large number of plastic parts to accumulate, making subsequent retrieval more difficult. The stacked plastic parts may also damage each other. Utility Model Content

[0006] A base, on the upper side of which a first slide rail is fixedly connected, a second slide rail is slidably connected to the side wall of the first slide rail, a third slide rail is slidably connected to the side wall of the second slide rail, a slider is slidably connected to the side wall of the third slide rail, and a clamping structure is installed on the slider;

[0007] The slider is equipped with a cleaning structure, which includes a rack fixedly connected to the side wall of the second slide rail. Two reciprocating screws are rotatably connected to the side wall of the slider, and the two reciprocating screws are connected by a pulley assembly. A rotating shaft is rotatably connected to the side wall of the slider. A bevel gear is fixedly sleeved on the outside of the rotating shaft and one of the reciprocating screws, and the two bevel gears mesh with each other. A spur gear is fixedly sleeved on the outside of the rotating shaft. Two fixed rods are fixedly connected to the side wall of the slider. A connecting rod is slidably connected to one side wall of each of the two fixed rods. A reciprocating block is rotatably connected to the side wall of the connecting rod. A cleaning plate is fixedly connected to the side wall of the connecting rod.

[0008] Preferably, a flipping structure is installed on the base. The flipping structure includes a support frame fixedly connected to the side wall of the base. A rotating shaft is rotatably connected to the side wall of the support frame. A flipping plate is fixedly sleeved on the outside of the rotating shaft. A rotating shaft is rotatably connected to the side wall of the first slide rail. A spur gear is fixedly sleeved on the outside of both the rotating shaft and the rotating shaft. The two spur gears mesh with each other. A spur rack is fixedly connected to the side wall of the second slide rail.

[0009] Preferably, the clamping structure includes a control motor fixedly installed on the side wall of the slider, a bidirectional screw fixedly installed at the output end of the control motor, two clamping plates threadedly connected to the outer side of the bidirectional screw, a second fixing rod fixedly connected to the side wall of the slider, and the two clamping plates slidably connected to the second fixing rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In this utility model, the movement of the slider on the third slide rail causes the spur gear one to mesh with the spur rack one, thereby causing the reciprocating screw to rotate to complete one cycle of reciprocating motion, which can drive the cleaning plate to clean the side wall of the clamping plate, avoiding the impact of residual plastic on the side wall of the clamping plate on subsequent handling, and reducing the manual cleaning process.

[0015] 2. In this utility model, the second slide rail drives the second spur rack to move. During the movement, it meshes with the second spur gear and drives the second spur gear to rotate, thereby causing the flipping plate to rotate. This allows the plastic parts placed on the upper side of the flipping plate by the robot arm to be flipped into the collection box, avoiding the situation of the plastic parts piling up and collapsing. It also makes the subsequent collection process easier and simpler for the staff. Attached Figure Description

Detailed Implementation

[0022] Reference Figures 1-5 A three-axis servo robot for injection molding, comprising:

[0023] A base 1 has a first slide rail 2 fixedly connected to its upper side. A second slide rail 3 is slidably connected to the side wall of the first slide rail 2. A third slide rail 4 is slidably connected to the side wall of the second slide rail 3. A slider 5 is slidably connected to the side wall of the third slide rail 4. The second slide rail 3, the third slide rail 4, and the slider 5 are controlled by hydraulic rods. The movement is controlled by the hydraulic rods through manual input commands. This is existing technology and will not be described in detail. A clamping structure is installed on the slider 5. The clamping structure includes a control motor 23 fixedly installed on the side wall of the slider 5. A bidirectional screw 24 is fixedly installed at the output end of the control motor 23. Two clamping plates 25 are threadedly connected to the outer side of the bidirectional screw 24. A second fixing rod 26 is fixedly connected to the side wall of the slider 5. The two clamping plates 25 are slidably connected to the second fixing rod 26.

[0024] A cleaning structure is installed on slider 5, which includes a rack 6 fixedly connected to the side wall of the second slide rail 3. Two reciprocating screws 7 are rotatably connected to the side wall of slider 5, and the two reciprocating screws 7 are connected by a pulley assembly 8, which consists of two pulleys and a belt. A rotating shaft 9 is rotatably connected to the side wall of slider 5. A bevel gear 10 is fixedly sleeved on the outer side of the rotating shaft 9 and one of the reciprocating screws 7, and the two bevel gears 10 mesh with each other. A spur gear 11 is fixedly sleeved on the outer side of the rotating shaft 9. When the robot arm picks up the item, slider 5 is moved first and then the third slide rail 4 is moved, so that the spur gear 11 will not mesh with the spur gear 11 during the movement of slider 5. When the plastic part is lowered and returned to the picking position, the slider 5 moves first and then the third slide rail 4 moves. This allows the slider 5 to drive the spur gear 11 to mesh with the spur gear 6 during its movement. Two fixed rods 12 are fixedly connected to the side wall of the slider 5. Connecting rods 13 are slidably connected to the side walls of the two fixed rods 12. Reciprocating blocks 14 are rotatably connected to the side walls of the connecting rods 13. Reciprocating blocks 14 can reciprocate along the slide groove on the outside of the reciprocating screw 7. A cleaning plate 15 is fixedly connected to the side wall of the connecting rod 13. A cleaning roller 16 is rotatably connected to the side wall of the cleaning plate 15. The cleaning roller 16 and the cleaning plate 15 together have a dual cleaning effect.

[0025] A flipping structure is installed on the base 1. The flipping structure includes a support frame 17 fixedly connected to the side wall of the base 1. A support plate 29 is fixedly connected between the support frame 17 and the base 1. A rotating shaft 18 is rotatably connected to the side wall of the support frame 17. A flipping plate 19 is fixedly sleeved on the outside of the rotating shaft 18. Four buffer springs 27 are fixedly connected to the side wall of the flipping plate 19. A sponge plate 28 is fixedly connected to one end of the four buffer springs 27. The sponge plate 28 and the buffer springs 27 can reduce the impact force when the robot puts down the plastic part and reduce the damage to the plastic part from the collision. A rotating shaft 20 is rotatably connected to the side wall of the first slide rail 2. A spur gear 21 is fixedly sleeved on the outside of both the rotating shaft 18 and the rotating shaft 20, and the two spur gears 21 mesh with each other. A spur rack 22 is fixedly connected to the side wall of the second slide rail 3.

[0026] In this invention, firstly, the operator inputs a command, causing the device to move slider 5 downwards after picking up the plastic part, followed by the movement of the third slide rail 4 and the second slide rail 3. When the robotic arm lowers the picked-up plastic part and returns to the picking position, the third slide rail 4 and the second slide rail 3 are moved first, followed by the movement of slider 5. Moving slider 5 allows spur gear 11 to mesh with rack 6. The rotation of spur gear 11 causes shaft 9 to rotate. Shaft 9 drives one reciprocating screw 7 to rotate via bevel gear 10. One reciprocating screw 7 drives the other reciprocating screw 7 via pulley assembly 8. The rotation of reciprocating screw 7 causes reciprocating block 14 to slide along the groove on the outer side of reciprocating screw 7, thereby causing connecting rod 13 to reciprocate outside fixed rod 12. During the meshing of spur gear 11 and rack 6, the reciprocating screw 7 is driven... The reciprocating block 14 performs a reciprocating motion, which causes the cleaning plate 15 and the cleaning roller 16 to clean the clamping plate 25, preventing residual plastic on the side wall of the clamping plate 25 from affecting subsequent handling and reducing the need for manual cleaning. During the movement of the robotic arm back to the handling position driven by the second slide rail 3, the movement of the rack 22 allows it to mesh with one of the spur gears 21. When meshed, the spur gear 21 can drive the other spur gear 21 to rotate, thereby causing the flipping plate 19 to flip, which in turn causes the sponge plate 28 to flip. During the flipping, the plastic parts placed on it can fall into the collection box through the inclined plane. During the movement to pick up the plastic parts, the flipping structure can also return the flipping plate 19 to the horizontal position, which will not affect the placement of the plastic parts and prevent the plastic parts from piling up and collapsing. It also makes the subsequent collection process easier and simpler for the staff.
