Technical Field

[0001] The utility model relates to the technical field related to an injection molding machine manipulator, in particular to a suction and clamping dual-function material taking mechanism for an injection molding machine manipulator. Background Art

[0002] The injection molding machine robot is a loading and unloading device specially equipped for injection molding production automation. After the injection molding is completed, the material-retrieving robot can be used to take the finished product to realize automated production to meet the needs of mass production. Therefore, the material-retrieving mechanism installed at the end of the injection molding machine robot also plays a vital role in automated production.

[0003] At present, the material-retrieving mechanism installed at the end of the injection molding machine's retrieving robot mostly uses clamping or negative pressure suction as the material-retrieving method. The material-retrieving means are relatively simple. When it is necessary to change the material-retrieving method to pick up the product, it is necessary to stop the machine and replace the retrieving mechanism first, which causes a waste of time.

[0023] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0024] Example: Figure 1-4 As shown, the present invention provides a dual-function material-retrieving mechanism for the manipulator of an injection molding machine, comprising a mounting top plate 1 mounted on the end of the manipulator and an I-shaped bottom plate 2 provided below the mounting top plate 1. A material clamping assembly and a material suction assembly are provided between the mounting top plate 1 and the I-shaped bottom plate 2. The material clamping assembly comprises a bidirectional material clamping cylinder 16, a bidirectional material clamping cylinder 2 15, and two clamping plates 2 8 connected to the piston ends of the bidirectional material clamping cylinder 2 15 via an L-shaped transmission member 1 9. Two symmetrically distributed clamping plates 13 are provided between the two clamping plates 2 8. The clamping plates 13 are connected to the piston ends of the bidirectional material clamping cylinder 16 via an L-shaped transmission member 2.

[0025] The suction assembly includes a suction cylinder 3 connected to the mounting top plate 1 via a connecting bracket 6, an I-shaped connector 11 connected to the piston rod of the suction cylinder 3, two symmetrically distributed adjustment modules, and a plurality of vacuum adsorption heads 5 arranged below the I-shaped connector 11. A ventilation chamber 17 is symmetrically provided in the I-shaped connector 11, a ventilation hole 18 is opened at the bottom of the ventilation chamber 17, and a connecting pipe 4 for connecting to the vacuum adsorption head 5 is provided at the bottom of the ventilation hole 18.

[0026] Among them, the adjustment module includes an electromagnet 12 installed on the outside of the I-shaped connector 11, an adjustment plate 21 slidingly arranged in the ventilation chamber 17, and a sliding through hole connected to one side of the ventilation chamber 17. A sealing sleeve 23 is provided at one end of the sliding through hole. Two movable rods 22 that slide in cooperation with the sliding through hole and can pass through the sealing sleeve 23 are installed on one side of the adjustment plate 21. A return spring 24 is sleeved on the outer wall of the movable rod 22. The two ends of the return spring 24 are respectively connected to the adjustment plate 21 and the inner wall of the ventilation chamber 17. A limit head is also provided at one end of the movable rod 22. The limit head is located on the outside of the I-shaped connector 11, and the adjustment plate 21 is wrapped with an elastic wear-resistant sleeve. A sealing ring is also provided between the inner wall of the sealing sleeve 23 and the outer wall of the movable rod 22 to improve the sealing performance. The adjustment plate 21 is made of a magnet or a material with a high iron content. Therefore, when the electromagnet 12 generates magnetic force due to power-on, the adjustment plate 21 will be attracted and move toward the electromagnet 12.

[0027] The magnetic force generated by the energized electromagnet 12 causes the adjustment plate 21 to move toward the electromagnet 12 and puts the return spring 24 in a stretched state. The through hole 25 is sealed by the adjustment plate 21, so that the through hole 25 is no longer connected to the ventilation chamber 17. After the electromagnet 12 is powered off, the adjustment plate 21 is moved away from the through hole 25 under the action of the elastic force of the return spring 24, so that the through hole 25, the ventilation chamber 17 and the ventilation hole 18 are connected. The outside air enters the vacuum adsorption head 5 through the ventilation chamber 17, so that the vacuum adsorption head 5 is no longer in a negative pressure state. There is no need to connect an additional inflation device, which can reduce the use of pipelines.

[0028] Among them, the two ventilation chambers 17 are connected through a ventilation flow channel 19, and a mounting hole is provided on one side of the ventilation flow channel 19. A negative pressure interface 20 is provided at one end of the mounting hole. A pipe is used to connect the negative pressure interface 20 and the vacuum pump. After starting the vacuum pump, the gas is extracted through the ventilation chamber 17, so that the vacuum adsorption head 5 forms a negative pressure to achieve product absorption.

[0029] Among them, the other side of the ventilation chamber 17 is connected to a plurality of through holes 25 for air intake. External air enters the ventilation chamber 17 through the through holes 25, so that the vacuum adsorption head 5 is no longer in a negative pressure state, and the product can be put down.

[0030] Among them, one side of the second clamping plate 8 and the first clamping plate 13 is provided with multiple clamping blocks 10 for clamping products. The clamping blocks 10 located on the second clamping plate 8 are arranged face to face with the clamping blocks 10 located on the first clamping plate 13. Since multiple clamping blocks 10 are provided, multiple products can be clamped at one time.

[0031] The bidirectional clamping cylinder 16 is installed on the top of the I-shaped base plate 2, and a cylinder bracket 14 for supporting the bidirectional clamping cylinder 2 15 is also provided on the outside of the bidirectional clamping cylinder 16.

[0032] Among them, four connecting columns 7 are provided between the bottom of the installation top plate 1 and the top of the I-shaped bottom plate 2. The four connecting columns 7 are distributed in a rectangular shape, and the installation top plate 1 and the I-shaped bottom plate 2 are connected by the connecting columns 7.

[0033] During operation, a pipeline is used to connect the negative pressure interface 20 and the vacuum pump, and the two-way clamping cylinder 16 and the two-way clamping cylinder 2 15 are used to drive the splint 13 and the splint 2 8 respectively, so that the splint 13 and the splint 2 8 are moved closer to or away from each other, and the clamping blocks 10 on the splint 13 and the splint 2 8 are used to clamp the product. The suction cylinder 3 drives the I-shaped connector 11, and the connecting pipe 4 drives the vacuum adsorption head 5, so that the vacuum adsorption head 5 is under the clamping block 10. After starting the vacuum pump, the gas is extracted through the ventilation chamber 17 to form a negative pressure on the vacuum adsorption head 5 to achieve product absorption.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
