[0023] The present invention will be described in detail below with reference to the embodiments shown in the accompanying drawings. However, the embodiments do not limit the scope of protection of the present invention, and any structural, methodological, or functional changes made by a person skilled in the art based on the embodiments are all included in the scope of protection of the present invention.

[0024] Example:

[0025] The utility model discloses a manipulator for unloading of injection molding machine. Figure 1-Figure 3 As shown, it includes a box body 1, which is a square box structure. A rectangular tube 2 is installed on all four sides of the box body 1. The rectangular tube 2 is plugged with a rectangular sleeve 8. The rectangular sleeve 8 can move along the rectangular tube 2 and cannot rotate circumferentially.

[0026] One end of the rectangular sleeve 8 extends into the interior of the box body 1 and is fixedly installed with a limit plate 3. Tension springs 5 ​​are installed between the two ends of each limit plate 3 and the box body 1. The tension springs 5 ​​make the limit plate 3 and the rectangular sleeve 8 have a force to extend outward. The other end of the rectangular sleeve 8 is plugged with an L-shaped rod 12. The L-shaped rod 12 is installed with a pressure plate 11 through a guide assembly 7 and a pressure sensor 10. The pressure sensor 10 is centrally arranged, and the guide assemblies 7 are symmetrically arranged on both sides of the pressure sensor 10. The guide assembly 7 is used to maintain the translational action of the pressure plate 11 and detect the pressure on the pressure plate 11 through the pressure sensor 10;

[0027] An adjustment assembly 6 is provided between the rectangular sleeve 8 and the L-shaped rod 12. The adjustment assembly 6 can adjust the extension length of the L-shaped rod 12 in the rectangular sleeve 8 and fix it according to the shape of the required injection molded product. The box body 1 is provided with a driving mechanism 4 for simultaneously pulling the rectangular sleeve 8, thereby achieving the action of clamping and releasing the injection molded product through the simultaneously actuated pressure plate 11;

[0028] Fans 13 are evenly installed on the front side of the box 1, and a filter assembly 9 is provided on the rear side of the box 1. The fan 13 is used to output cooling air to cool the clamped injection molded products, and the filter assembly 9 can filter the incoming air to prevent impurities from adhering to the injection molded products.

[0029] Specifically, such as Figure 3 As shown, the guide assembly 7 includes a guide cylinder 72 and a guide rod 71. A pair of guide cylinders 72 are fixedly installed on the end of the L-shaped rod 12 away from the rectangular sleeve 8. The guide cylinders 72 are all plugged with guide rods 71, and one end of the guide rod 71 is fixedly assembled with the pressure plate 11; the displacement of the pressure plate 11 caused by clamping will cause the guide rod 71 to move along the guide cylinder 72 to ensure the accuracy of the translation of the pressure plate 11.

[0030] Specifically, the driving mechanism 4 includes a worm reduction motor 43 and a winding roller 42. The winding roller 42 is rotatably installed inside the box body 1. The winding roller 42 has four wire-receiving slots, and a steel cable 41 is fixedly installed between each wire-receiving slot and the limit plate 3. A worm reduction motor 43 is fixedly installed on the rear side of the box body 1. The output end of the worm reduction motor 43 extends into the box body 1 and is connected to the winding roller 42; the worm reduction motor 43 can rotate the winding roller 42, thereby simultaneously reeling in or releasing the steel cable 41 to complete the action of pulling the limit plate 3. Due to the worm gear structure in the worm reduction motor 43, it has reverse braking capability, which is more conducive to the clamping action.

[0031] Specifically, the adjustment component 6 includes a positioning hole 61 and a bolt group 62. The L-shaped rod 12 is evenly provided with positioning holes 61. The rectangular sleeve 8 is provided with a pair of through holes at one end away from the limit plate 3. The bolt group 62 passes through the aligned through holes and positioning holes 61 and is locked. By adjusting the insertion depth of the L-shaped rod 12, the positioning holes 61 at different positions can be aligned with the through holes and fixed by the installed bolt group 62, so that cubes and rectangular products of different sizes can be clamped.

[0032] Specifically, such as Figure 4 、 Figure 5As shown, the filter assembly 9 includes a storage box 93 and filter discs 94. The storage box 93 is fixedly installed on the rear side of the box body 1. An air inlet aligned with one end of the storage box 93 and the box body 1 is opened. Filter discs 94 are evenly slidably assembled in the storage box 93. The number of filter discs 94 is 3 to 5. One filter disc 94 is located between the air inlets. The filter discs 94 are used to filter the air passing through the air inlets. The two ends of the storage box 93 are open, and a gap is left between the top of the storage box 93 and the box body 1. The box body 1 is fixedly mounted with a lead screw module 91 on the rear side, and a paddle 92 is fixedly mounted on the slider of the lead screw module 91. The paddle 92 passes through the gap and abuts against the filter 94 away from the air inlet. The filter 94 is slidably mounted in the storage box 93 by means of interference fitting, which can avoid movement due to vibration. When the lead screw module 91 is working, the filter 94 can be moved at a fixed distance to eject the filter 94 that has been used for a long time and push the next filter 94 between the air inlets, so that regular replacement can be achieved and manual operation can be avoided.

[0033] The working principle of this embodiment is as follows:

[0034] When in use, the manipulator is installed on the turning mechanism. As the guide rail car and the cross slide move, the box 1 in the manipulator can be moved between the separated molds to align the product that has just been injection molded. At this time, the driving mechanism 4 pulls back the pressing plate 11 so that the pressing plate 11 is clamped around the product. The large-scale clamping can avoid local deformation of the product.

[0035] At the same time, the fan 13 works to blow filtered air on the product to help the product cool quickly during the movement. After the product is taken out, it is turned horizontally. After the pressing plate 11 is reset, the product falls on the platform to complete the unloading.

[0036] In addition, the insertion depth of the L-shaped rod 12 in the rectangular sleeve 8 can be adjusted by adjusting the component 6 to adjust the clamping action of the pressure plate 11, which can adapt to the shapes and sizes of more box products; the filter component 9 can maintain the filtering effect by regularly replacing the filter disc 94.

[0037] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
