[0026] In order to more fully understand the technical content of the present invention, the technical solution of the present invention is further introduced and illustrated in conjunction with specific embodiments below.

[0027] This embodiment is an automatic water-cutting device for injection molded parts. Figure 1 As shown, the automatic water gate cutting device includes a conveying mechanism 10, a workbench 20, a clamping mechanism 30, a cutting mechanism 40 and a multi-axis manipulator 50. The conveying mechanism 10 is used to receive the injection molded semi-finished product 90 to be processed from the outside (such as a manipulator or manual) and transfer the injection molded semi-finished product 90 to the workbench 20. The workbench 20 is used to receive the injection molded semi-finished product 90 from the conveying mechanism 10 and transfer the injection molded semi-finished product 90 to the clamping mechanism 30. The clamping mechanism 30 is used to clamp a single plastic part on the injection molded semi-finished product 90. The cutting mechanism 40 is used to cut along the gate connected to the plastic part when the clamping mechanism 30 clamps the single plastic part. When the single plastic part on the injection molded semi-finished product 90 is cut, the multi-axis manipulator 50 will absorb the plastic part on the clamping mechanism 30 and transfer it to the tray 60 for placement. When the tray 60 is full of plastic parts, the tray 60 is pushed into the material box 70 for storage and waiting to be taken away.

[0028] like Figure 2The figure shows a stereoscopic view of the conveying mechanism 10 and the workbench 20. The conveying mechanism 10 includes a vertical lifting platform 11, a horizontal translation platform 12 and a manipulator 13. The lifting platform 11 is used to receive the injection molded semi-finished product 90 to be processed from the outside (such as a manipulator or manual), and lower the injection molded semi-finished product 90 to the translation platform 12. The lifting platform 11 is fixed on a horizontal plate 111, and the horizontal plate 111 is controlled to rise and fall by a vertical linear motor 112. A sensor 113 is also provided on the top of the linear motor 112. When the lifting platform 11 is at the highest point, the sensor 113 is used to sense whether the lifting platform 11 has the injection molded semi-finished product 90. The translation platform 12 is arranged on a bottom plate 121, and a rodless cylinder 122 and a slide rail 123 are also provided on the bottom plate 121. The rodless cylinder 122 is used to drive the translation platform 12 to move back and forth along the slide rail 123. When the translation table 12 moves to the position corresponding to the linear motor 112 (that is, the end of the stroke), the lifting table 11 descends and places the injection molded semi-finished product 90 on the translation table 12, and then the translation table 12 translates in the opposite direction, and then the lifting table 11 rises to the top to receive the next injection molded semi-finished product 90.

[0029] The translation platform 12 will receive the injection molded semi-finished product 90 at the end of the stroke and then translate to the other end of the stroke. At this time, the robot 13 will grab the injection molded semi-finished product 90 on the translation platform 12 and transfer it to the workbench 20. Figure 2 As shown, the manipulator 13 includes a feeding jaw 131, an intermediate jaw 132 and a discharging jaw 133. The feeding jaw 131, the intermediate jaw 132 and the discharging jaw 133 are arranged in a straight line along the translation direction of the translation platform 12. The feeding jaw 131, the intermediate jaw 132 and the discharging jaw 133 are all pneumatic jaws. The workbench 20 is provided with a first bearing position 21 and a second bearing position 22 for placing the injection molded semi-finished product 90. The arrangement direction of the first bearing position 21 and the second bearing position 22 is parallel to the arrangement direction of the feeding jaw 131, the intermediate jaw 132 and the discharging jaw 133. The first bearing position 21 is arranged on a side close to the translation platform 12. The feeding jaw 131 is used to grab the injection molded semi-finished product 90 on the translation platform 12 and transfer it to the first bearing position 21. The middle clamp 132 is used to transfer the injection molded semi-finished product 90 or the cut injection molded semi-finished product waste on the first carrying position 21 to the second carrying position 22. The unloading clamp 133 is used to transfer the injection molded semi-finished product waste at the second carrying position 22 to the waste port 91 ( Figure 1). During the loading process, the feeding jaw 131 transfers the first injection molded semi-finished product 90 to the first loading position 21, and then the middle jaw 132 grabs the first injection molded semi-finished product 90 and transfers it to the second loading position. The feeding jaw 131 then grabs the second injection molded semi-finished product 90 and places the second injection molded semi-finished product 90 on the first loading position 21, so that the first loading position 21 and the second loading position 22 are both filled with injection molded semi-finished products 90. When the two injection molded semi-finished products 90 on the workbench have been sheared, the unloading jaw 133 grabs the waste injection molded semi-finished product on the second loading position 22 and transfers it to the waste port 91 ( Figure 1 ) is discarded, and the middle clamp 132 grabs the injection molding semi-finished product waste at the first carrying position 21 and transfers it to the second carrying position 22, and finally the unloading clamp 133 grabs the injection molding semi-finished product waste at the second carrying position 22 again and transfers it to the waste port 91 ( Figure 1 ) and discarded.

[0030] In other embodiments, the workbench may also have only one loading position for placing the injection molded semi-finished product. The manipulator may only include a feeding jaw and a discharging jaw, which are arranged in a straight line along the translation direction of the translation table. The feeding jaw is used to grab the injection molded semi-finished product on the translation table and transfer it to the loading position. The discharging jaw is used to transfer the injection molded semi-finished product waste that has been cut and is in the loading position to the waste port.

[0031] like Figure 2 As shown, the workbench 20 is provided with a first bearing position 21 and a second bearing position 22 for placing the injection molded semi-finished products. The arrangement direction of the first bearing position 21 and the second bearing position 22 is perpendicular to the translation direction of the workbench 20. The first bearing position 21 and the second bearing position 22 are both arranged on the top surface of a vertical rod 23. A motor 24 is provided below the vertical rod 23, and the motor 24 drives the vertical rod 23 and the first bearing position 21 and the second bearing position 22 to rotate around the vertical direction through a coupling 25, so as to facilitate the cutting of the plastic parts at various positions. The workbench 20 is arranged on two slide rails 26, and the workbench 20 is driven by a cylinder 27 to move back and forth in a straight line along the slide rails 26.

[0032] In other embodiments, a bearing position for placing the injection-molded semi-finished product may be provided on the workbench. The bearing position is provided on the top surface of a vertical rod, and a motor is provided under the vertical rod, and the motor is used to drive the vertical rod and the bearing position to rotate around the vertical direction.

[0033] like Figure 3As shown, the clamping mechanism 30 includes a pneumatic clamp 31, a first cylinder 32 and a second cylinder 33. The pneumatic clamp 31 is used to clamp a single plastic part on the injection molded semi-finished product 90 on the first load position 21 and the second load position 22 of the workbench 20. The first cylinder 32 is used to drive the pneumatic clamp 31 to move horizontally and linearly along a direction perpendicular to the moving direction of the workbench 20. The second cylinder 33 is used to drive the pneumatic clamp 31 to move horizontally and linearly along a direction parallel to the moving direction of the workbench 20. Specifically, the first cylinder 32 adopts a rodless cylinder, and the first cylinder 32 drives a movable plate 34 to move linearly along a slide rail 35. The second cylinder 33 is fixed on the movable plate 34. A slide rail 36 is provided on the second cylinder 33, and the slide rail 36 is slidably connected to another movable plate 37 above. A pad 38 is fixed on the movable plate 37, and the pneumatic clamp 31 is fixed on the pad 38.

One of the clamping mechanisms 30 corresponds to the first bearing position 21, and the other clamping mechanism 30 corresponds to the second bearing position 22. In other embodiments, the workbench may only have one bearing position for placing the injection molded semi-finished product, and only one clamping mechanism is provided accordingly.

[0035] Combination Figure 3 , 4 As shown, the cutting mechanism 40 includes a motor 41, a control block 42 and two control rods 43 that are kept parallel to each other. The ends of the two control rods 43 are respectively fixed with shear blocks 431, and the blades of the upper and lower shear blocks 431 are opposite. The motor 41 drives the control block 42 to move in a straight line perpendicular to the moving direction of the workbench 20 through a screw structure. The side of the control block 42 parallel to its own moving direction is provided with two upper and lower inclined grooves 421. The control rod 43 is arranged on the side of the control block 42, and the control rod 43 corresponds to the inclined groove 421 one by one. Each control rod 43 is provided with a roller (not shown) inserted into the corresponding inclined groove 421. The cutting mechanism 40 also includes a bottom plate 44, a middle plate 45 and a top plate 46. The motor 41, the control block 42 and the control rod 43 are all arranged on the top plate 46. The two control rods 43 are all penetrated by two guide rods 431, and the two guide rods 431 are fixed on the top plate 46, and a compression spring 432 is sandwiched between the two control rods 43. When the control block 42 moves linearly back and forth, the control block 42 drives the two control rods 43 to move closer to or away from each other in parallel through the inclined slot 421 and the roller, and the compression spring 432 maintains a mutual repulsive force between the two control rods 43.

[0036] Combination Figure 3 , 4As shown, the middle plate 45 is arranged on the bottom plate 44 and can adjust the relative position along a straight line perpendicular to the moving direction of the workbench 20. Specifically, a vertical plate 451 is fixed on the side of the middle plate 45, and the vertical plate 451 extends downward. A long hole 452 is provided below the vertical plate 451, and a threaded hole 441 is provided at the position of the bottom plate 44 corresponding to the long hole 452. The length direction of the long hole 452 is perpendicular to the moving direction of the workbench 20. A screw passes through the long hole 452 and is screwed into the threaded hole 441 of the bottom plate 44 to fix the relative position of the middle plate 45 and the bottom plate 44 after the position of the middle plate 45 relative to the bottom plate 44 is adjusted.

[0037] Combination Figure 3 , 4 As shown, the top plate 46 is arranged on the middle plate 45 and can adjust the relative position along a straight line parallel to the moving direction of the workbench 20.

A compression spring 462 is arranged on the other side of the top plate 46. The differential head 461 and the compression spring 462 are on the same straight line, and the line connecting the differential head 461 and the compression spring 462 is parallel to the moving direction of the workbench 20. The position of the top plate 46 relative to the middle plate 45 can be fine-tuned by twisting the differential head 461.

[0038] In this embodiment, two cutting mechanisms 40 are provided and are symmetrical to each other. One cutting mechanism 40 corresponds to the first carrying position 21, and the other cutting mechanism 40 corresponds to the second carrying position 22. In other embodiments, the workbench may have only one carrying position for placing the injection molded semi-finished product, and only one cutting mechanism is provided accordingly.

[0039] like Figure 5As shown, the automatic water inlet cutting device also includes a suction head 51. The multi-axis manipulator 50 is used to control the suction head 51 to suck the cut plastic parts 92 on the injection semi-finished product 90 at the clamping mechanism 30 and move the plastic parts 92 to the tray 60. There are two trays 60 to be placed with plastic parts 92 side by side, and they are placed on the track 61 and can slide along the track 61. A movable positioning wedge 62 is provided on the track 61, and the positioning wedge 62 is used to insert into the gap of the tray 60 so that the tray 60 cannot move on the track 61. The positioning wedge 62 is controlled by a telescopic cylinder under the tray 60 (not shown). The multi-axis manipulator 50 has linear movement freedom of the X-axis (the length direction of the track 61), the Y-axis (perpendicular to the length direction of the track 61) and the Z-axis (perpendicular to the tray 60). The X-axis and Y-axis linear movement freedom of the multi-axis manipulator 50 are realized by linear motors 52 and 53 respectively, while the Z-axis linear movement freedom is realized by a servo motor 54 and a screw structure. The servo motor 54 drives a vertical plate 55 to move up and down through a lead screw structure, and two suction heads 51 are respectively arranged on the vertical plate 55. The vertical plate 55 is also provided with a vertical cylinder 56 for driving the suction head 51 to move up and down, and two slide rails 57 slidably connected to the suction head 51. When working, the multi-axis manipulator 50 moves the suction head 51 to the plastic part 92 of the clamping mechanism 30, and the suction head 51 descends and sucks the plastic part 92, until both suction heads 51 suck the plastic part 92, and then the multi-axis manipulator 50 moves to the top of the material tray 60, and places the two plastic parts 92 into the material tray 60 respectively.

When both material trays 60 are filled with plastic parts, the multi-axis manipulator 50 drives the crossbar 59 to move to the end of the material tray 60, and the vertical cylinder 82 extends to make the horizontal push rod 81 drop to the same height as the two vertical rods 83 of the horizontal push rod 81 and the material tray 60. Then the multi-axis manipulator 50 drives the crossbar 59 to move along the length direction of the track 61, and the crossbar 59 pushes the material tray 60 to slide along the track 61 through the horizontal push rod 81 into the material box 70 for storage. The material box 70 of this embodiment is driven to rise and fall vertically by a motor screw mechanism 71 below. A single-hole cylinder 72 for supporting the material box 70 is provided below the material box 70. The output shaft of the single-hole cylinder 72 is fixedly connected to the bottom surface of the material box 70. The material box 70 is provided with multiple layers of space for placing the material trays 60. After two material trays 60 are pushed in each time, the motor screw mechanism 71 pushes the material box 70 up a distance so that the space for placing the material trays 60 in the next layer can be aligned with the track 61.
