DETAILED DESCRIPTION

[0027] like Figures 1 to 6 As shown, the present invention discloses an automatic material dividing and cutting machine dedicated to an injection molding machine, comprising a material conveying component 1, a cutting component 2 arranged above the material conveying component 1, a material guiding component 3 arranged at the end of the material conveying component 1, a dividing component 4 arranged at the end of the material guiding component 3, and a first collecting area and a second collecting area located below the dividing component 4. During injection molding, in order to improve efficiency, multiple materials 5 are connected together after injection molding, so the material conveying component 1 is used to convey two connected materials 5, the cutting component 2 cuts the connected materials 5 into single materials 5, and after the single materials 5 enter the material guiding component 3 in turn, the material guiding component 3 conveys the single materials 5 to the dividing component 4, and the dividing component 4 is used to identify materials 5 with or without defects and discharge the two types of materials 5 separately to the first collecting area and the second collecting area; the first collecting area and the second collecting area are used to classify and collect unqualified products and qualified products, respectively.

[0028] In the embodiment of the present invention, the cutting component 2 adopts the existing laser cutting equipment, which is controlled by the three-axis moving mechanism, and can cut the two connected materials 5. Those skilled in the art can understand that the initial material 5 can be moved to the material conveying component 1 by manual or mechanical hands or other vibration material 5 transmission equipment, and after its direction is adjusted, it can be cut on the material conveying component 1, and then transferred to the material guide component 3, and after being guided and transmitted by the material guide component 3, it enters the material separation component 4 for material separation. By adopting the above method, the product can be separated in time, thereby improving the efficiency of product inspection and reducing the intensity of manual labor.

[0029] Specifically, the material distribution assembly 4 disclosed in the present invention includes a pushing assembly 6, a lower stopper 7, a lower proximity switch 8, a lower elastic reset assembly 9, an upper stopper 10, an upper proximity switch 11, an upper elastic reset assembly 12 and a detection locking assembly. The pushing direction of the material 5 is the longitudinal direction, and the conveying direction of the material 5 conveying group in the figure is also along the longitudinal direction, and the guiding direction of the material guide assembly 3 is along the transverse direction. The lower stopper 7 is located on the upper side of the material 5 and is connected to the lower elastic reset assembly 9. The lower stopper 7 and the partition 20 are vertically separated to form a space for the material 5 to pass through. The upper stopper 10 is located on the upper side of the lower stopper 7 and is connected to the upper elastic reset assembly 12. The upper stopper 10 and the lower stopper 7 are in contact with each other.

[0030] The lower proximity switch 8 and the upper proximity switch 11 correspond to the lower block 7 and the upper block 10 respectively, wherein the lower proximity switch 8 is further away from the push assembly 6 relative to the upper proximity switch 11, and the push assembly 6 is used to push the material 5 through the lower block 7. As the material 5 moves along the longitudinal direction, the lower surface of the lower block 7 can pass over the upper surface of the entire material 5. The detection and locking assembly can detect defects on the surface of the material 5. When defects on the surface of the material 5 are detected, the detection and locking assembly locks the lower block 7 and the upper block 10, and the material 5 pushes the upper block 10 and the lower block 7 to move together. The upper proximity switch 11 first senses the signal, and the push assembly 6 retracts at this time, and the material 5 falls into the first collection area to complete the collection of unqualified materials 5; when there are no defects on the surface of the material 5, after the material 5 moves to the limit relative to the lower block 7, the material 5 pushes the lower block 7 to move, the lower proximity switch 8 senses the signal, the push assembly 6 retracts, and the material 5 falls into the second collection area to complete the collection of qualified materials 5. By adopting the above method, the products can be divided in time, thereby improving the product testing efficiency and reducing the labor intensity.

[0031] The upper block 10 and the lower block 7 of the present invention are both in the shape of long columns and are arranged in the horizontal direction. When the upper block 10 and the lower block 7 are locked, the upper block 10 and the lower block 7 can be displaced together in the longitudinal direction. When the upper block 10 and the lower block 7 are disconnected, the lower block 7 can move alone, and the upper block 10 is not affected. In some other embodiments, the detection locking assembly includes a machine vision detector, which is installed on the lower side of the lower block 7. When the machine vision detector passes over the upper surface of the entire material 5, the detection of the entire surface is completed. The detection locking assembly also includes an electromagnet, which is installed on the inner side of the upper block 10 and the lower block 7 respectively, and the locking or disconnection between the upper block 10 and the lower block 7 is achieved by electric control.

[0032] In the embodiment of the present invention, the upper elastic reset assembly 12 includes a bottom plate and an upper spring, the bottom plate is fixed on the mounting platform, the bottom plate is connected to the upper block 10 through the upper spring, and a slide groove for the upper block 10 to move along the longitudinal direction is installed on the mounting platform. When the upper block 10 moves, the upper spring can drive the upper block 10 to return to its original position. Similarly, the lower elastic reset assembly 9 includes a lower spring, the bottom plate is connected to the lower block 7 through the lower spring, and a slide groove for the lower block 7 to move along the longitudinal direction is installed on the mounting platform, which can improve the stability of the upper block 10 and the lower block 7 when moving.

[0033] In this embodiment, the detection locking assembly includes a support column 13 and a detection column 14. The support column 13 and the detection column 14 are cylindrical as a whole. A plurality of downward sliding holes 15 are evenly arranged in the lower block 7 along the horizontal direction. The detection column 14 is slidably installed in the downward sliding hole 15. The length of the detection column 14 is substantially consistent with the length of the downward sliding hole 15. The lower end of the detection column 14 forms a spherical surface to facilitate the detection of the upper surface of the material 5. The lower end of the detection column 14 abuts against the upper surface of the material 5. The upper block 10 is installed on the upper side of the lower block 7. A plurality of upper sliding holes 16 are evenly arranged in the upper block 10 along the horizontal direction. The support column 13 is slidably installed in the upper sliding hole 16. The lower end of the support column 13 abuts against the upper end of the detection column 14. In order to prevent the support column 13 from falling out, the lower block 7 has a wider width. When the lower block 7 moves alone, the support column 13 in the upper block 10 can be temporarily supported.

[0034] It should be noted that there are two main types of defects detected here, one is a pit defect and the other is a convex defect. When there is a pit defect, the detection column 14 can move downward and go deep into the pit. At this time, the support column 13 also moves downward to the lower slide hole 15 under the action of gravity. The interface between the upper block 10 and the lower block 7 is blocked by the support column 13, so that the lower block 7 cannot move alone, which plays a locking role. Similarly, when there is a convex defect, the convexity can push the detection column 14 upward for a displacement. After being pushed up, the detection column 14 can extend upward into the upper slide hole 16. The interface between the upper block 10 and the lower block 7 is blocked by the detection column 14, so that the lower block 7 cannot move alone, which can also play a locking role.

[0035] Of course, in order to ensure that the detection column 14 can be lifted up more sensitively, the lower end of the downward sliding hole 15 can be enlarged, thereby accommodating a larger area of ​​the protrusion. The above is only a further improvement of the embodiment of the present invention, and those skilled in the art should be able to understand it.

[0036] In this embodiment, an elastic support device 17 is installed in the upper sliding hole 16, and the elastic support device 17 is used to connect the support column 13 and the upper stop block 10. In the present invention, the elastic support device 17 adopts a spring, and the upper end of the spring is connected to the top of the upper sliding hole 16, and the lower end is connected to the support column 13, which can provide a downward elastic supporting force for the support column 13, making its movement process more stable.

[0037] In this embodiment, a limit head 18 is formed at the upper end of the detection column 14, and a limit groove 19 corresponding to the limit head 18 is formed at the upper end of the lower sliding hole 15, which can be used to limit the detection column 14 to prevent the detection column 14 from falling out.

[0038] In this embodiment, a partition 20 is provided between the first collection area and the second collection area, and the thickness of the partition 20 is relatively thin, so as to prevent the material 5 from being directly placed on the partition 20. The pushing assembly 6 includes a linear displacement device 21, a push plate 22 connected to the output end of the linear displacement device 21, and the push plate 22 includes a vertical plate and a horizontal plate perpendicular to the vertical plate. The horizontal plate is also used to support the material 5, and the upper end of the vertical plate extends upward and exceeds the upper surface of the material 5. When the push plate 22 moves to the lower stopper 7, it can push the lower stopper 7 to move together, thereby realizing the material separation operation.

[0039] In this embodiment, a column groove 23 is provided at the upper end of the partition 20, and a roller 24 is installed in the column groove 23 as a rolling limiter. The roller 24 is also used to support the material 5 in a rolling manner. The material 5 can fall to the first collection area or the second collection area in time, which can make the operation of the device more stable. A support rod 25 is fixed to the side of the partition 20, and the support rod 25 is connected to a vibration cylinder 26. The vibration cylinder 26 can drive the support rod 25 and the partition 20 to vibrate vertically. By using the vibration cylinder 26 to drive the partition 20 to vibrate, it can further prevent the material 5 from being directly placed on the partition 20, and reduce the possibility of interference between the front and rear materials 5. By setting the vibration cylinder 26, the initial height of the support rod 25 can also be adjusted, and the initial gap between the roller 24 and the lower baffle can be adjusted to meet actual needs.

[0040] In this embodiment, the material guide assembly 3 includes a U-shaped track 27, an open slot 28 is provided at the bottom of the track 27, a pressing plate 29 is slidably installed in the open slot 28, the pressing plate 29 is connected to a clamping device 30, and the clamping device 30 is installed at the bottom of the track 27. The clamping device 30 of the present invention includes a motor, a rack and a gear, the rack is arranged at the bottom of the track 27 in the horizontal direction, the motor is fixed to the lower end of the pressing plate 29, the pressing plate 29 is slidably installed in the open slot 28, the motor is slidably installed at the bottom of the track 27, the output end of the motor is connected to the gear, and the gear is meshed with the rack. When the motor drives the gear to rotate, the gear is meshed with the rack, and the gear can drive the motor and the pressing plate 29 to move, thereby pushing the material 5 to the end of the material guide assembly 3.

[0041] In this embodiment, the material conveying assembly 1 includes a conveyor belt 31, a conveyor roller 32 for tensioning the conveyor belt 31, a bracket 33 for supporting the conveyor roller 32, and a rotation driving device 34 for driving the conveyor roller 32 to rotate.

Those skilled in the art can make corresponding conventional settings as needed, which will not affect the main inventive concept of the present invention application.

[0042] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it.
