Description

Technical Field

[0001] The utility model relates to nut feeding equipment of injection molding equipment, in particular to a step-type nut feeding equipment. Background Art

[0002] In the injection molding process, the process of pre-embedded nuts in the mold is usually involved, and its purpose is to mold the nuts and the injection molded workpiece together. In order to improve the matching degree between the nuts and the injection molded workpiece, the existing nuts are generally designed to be stepped, that is, one end of the nut has a step protruding outward. For the nut feeding mechanism, the vibration plate can be matched with the dividing plate to realize the nut discharge, and then the pushing mechanism can be used to push the nuts in the dividing plate out for the manipulator to take the material. However, in the existing dividing plate, the step-type nuts are arranged in a stacked manner from top to bottom. Under the influence of gravity, the two step-type nuts at the bottom will form a stress that abuts against each other. When the push rod of the pushing mechanism pushes the step-type nut at the bottom, the steps of the two nuts will interfere with each other, that is, the step-type nut at the bottom and the penultimate step-type nut will rub against each other or even get stuck, resulting in the situation that the pushing is not smooth or even the nut cannot be pushed out. This will cause the action of embedding the nut in the injection mold to fail. Because there is no nut in the mold, the workpiece after injection molding will also become a defective product, which will cause a waste of resources. Utility Model Content

[0022] The present invention will be described in more detail below with reference to the accompanying drawings and embodiments.

[0023] The utility model discloses a stepped nut feeding device, combined with Figures 1 to 6As shown, it includes a machine table 1, on which a material distribution mechanism 2 and a feeding mechanism 3 for conveying stepped nuts 100 into the material distribution mechanism 2 are provided. The material distribution mechanism 2 includes a plurality of vertical material troughs 20, and the lower ends of the vertical material troughs 20 are provided with a push hole 21 and a positioning pin hole 22, and the positioning pin hole 22 is arranged above the push hole 21. The rear side of the material distribution mechanism 2 is provided with a push mechanism 4, and the moving end of the push mechanism 4 is provided with a plurality of push rods 40 and a plurality of positioning pins 41. The rod 40 is aligned with the pushing hole 21 one by one, and the positioning pin 41 is aligned with the positioning pin hole 22 one by one. When the pushing mechanism 4 drives the pushing rod 40 and the positioning pin 41 to move forward, the positioning pin 41 enters the positioning pin hole 22 and is inserted into the second stepped nut 100 from the bottom in the vertical trough 20. At the same time, the pushing rod 40 enters the pushing hole 21 and pushes the first stepped nut 100 from the bottom in the vertical trough 20 out of the pushing hole 21.

[0024] In the above structure, the feeding mechanism 3 can convey the step-type nuts 100 one by one into the distributing mechanism 2 by means of vibration feeding or the like, so that the step-type nuts 100 are stacked in sequence from top to bottom in a plurality of vertical troughs 20. On this basis, a pushing hole 21 and a positioning pin hole 22 are provided at the lower end of the vertical trough 20 at the same time, and the positioning pin hole 22 is located above the pushing hole 21. Correspondingly, a plurality of pushing rods 40 and a plurality of positioning pins 41 are provided at the moving end of the pushing mechanism 4. When the pushing mechanism 4 drives the pushing rod 40 and the positioning pin 41 to move forward, the pushing rod 40 is aligned one by one with the pushing hole 21, and the positioning pin 41 is aligned with the positioning pin hole 22. They are aligned one by one, so the locating pin 41 enters the locating pin hole 22 and is inserted into the second stepped nut 100 from the bottom in the vertical trough 20. The second stepped nut 100 from the bottom is positioned by using the locating pin 41, so that the first stepped nut 100 from the bottom is not subjected to the pressure of the upper nut. At the same time, the pushing rod 40 enters the pushing hole 21 and pushes the first stepped nut 100 from the pushing hole 21. In the process of pushing out the first stepped nut 100 from the bottom, the two adjacent stepped nuts 100 will not interfere with each other, which effectively avoids the step nut 100 from being stuck, thereby achieving smooth pushing and improving the injection molding manufacturing yield.

[0025] The step-type nut feeding device in this embodiment can directly feed the material to the material taking rod on the manipulator. Before this, it is necessary to first receive the step-type nut 100 pushed out by the material dividing mechanism 2, and then use the manipulator to take the material. Figure 1 and Figure 2As shown, a material receiving mechanism 5 is provided at the front side of the material dividing mechanism 2 and a material unloading space 6 of a preset width is formed between the two.

[0026] Combination Figure 1 , Figure 2 and Figure 6 As shown, in this embodiment, the material receiving mechanism 5 includes a material receiving vertical plate 50 and a material receiving driving mechanism 51 for driving the material receiving vertical plate 50 to move forward and backward. A plurality of material receiving pins 52 are provided on the rear side of the material receiving vertical plate 50, and the material receiving pins 52 are aligned one by one with the material pushing holes 21.

[0027] In the above structure, the material receiving driving mechanism 51 is used to drive the material receiving vertical plate 50 to move forward and backward, and a plurality of material receiving pins 52 are used to receive the step-type nut 100 from the material pushing hole 21, and then the robot is controlled to enter the unloading space 6, and then the step-type nut 100 is removed from the material receiving pins 52. In this embodiment, the material receiving mechanism 5 is set up so that the step-type nut 100 is pre-taken out first. After checking that the step-type nut 100 has been correctly assembled on the material receiving pins 52 of the material receiving mechanism 5, the robot is used to pick up the nut from the material receiving mechanism 5. In this embodiment, the material receiving mechanism 5 is set up to play the role of pre-taking materials, which facilitates the inspection of the removal of the nut and avoids the situation where the nut is missed due to the robot directly taking the nut from the material pushing hole 21.

[0028] In order to facilitate pushing the stepped nut 100 toward the material taking rod of the manipulator, in this embodiment, see Figure 6 The rear side of the material receiving vertical plate 50 is provided with a material receiving and withdrawing plate 53 and a withdrawing cylinder 54 for driving the material receiving and withdrawing plate 53 to move forward and backward. The material receiving pin 52 passes through the material receiving and withdrawing plate 53 and the two are slidably matched.

[0029] Regarding the preferred structure of the pushing mechanism 4, in this embodiment, please refer to Figure 4 The pushing mechanism 4 includes a pushing motion plate 42 and a pushing cylinder 43 for driving the pushing motion plate 42 to move forward and backward. The pushing rod 40 and the positioning pin 41 are both arranged on the pushing motion plate 42.

[0030] On this basis, the push mechanism 4 includes a guide slide bar 44, the front end of which is fixedly connected to the material distribution mechanism 2, and a sliding sleeve 45 is fixed on the push motion plate 42, and the guide slide bar 44 passes through the sliding sleeve 45 and the two slide together. Among them, this embodiment can make the push motion plate 42 move straight back and forth by providing the guide slide bar 44 and the sliding sleeve 45 that cooperate with each other, thereby keeping the push rod 40 aligned with the push hole 21, and the positioning pin 41 aligned with the positioning pin hole 22.

[0031] As a preferred embodiment, the pusher mechanism 4 includes at least two guide slide bars 44, and the front ends of the guide slide bars 44 are fixedly connected to the material distribution mechanism 2 by screws. In addition to making the pusher motion plate 42 move straight, the guide slide bars 44 also support the pusher mechanism 4.

[0032] In this embodiment, see Figure 4 , the diameter of the push rod 40 is larger than the hole diameter of the step nut 100, and the diameter of the positioning pin 41 is smaller than the hole diameter of the step nut 100. Based on the above diameter setting, the push rod 40 can effectively push the step nut 100, and the positioning pin 41 can be inserted into the step nut 100. In practical applications, the diameter of the push rod 40 can be slightly larger than the hole diameter of the step nut 100, and the diameter of the positioning pin 41 can be slightly smaller than the hole diameter of the step nut 100.

[0033] Regarding the preferred structure of the material distribution mechanism 2, Figures 1 to 3 As shown, the material dividing mechanism 2 includes a material dividing rear plate 23 and a material dividing front plate 24 covering the front side of the material dividing rear plate 23, the vertical material trough 20 is opened on the material dividing rear plate 23, and the material pushing holes 21 are opened on the material dividing front plate 24 and the material dividing rear plate 23. The material dividing rear plate 23 is vertically fixed on the machine platform 1.

[0034] In order to improve the feeding efficiency, in the present embodiment, the feeding mechanism 3 is a vibration plate feeding mechanism, and the feeding mechanisms 3 are respectively provided on the left and right sides of the material dividing mechanism 2 .

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions or improvements made within the technical scope of the present invention should be included in the scope of protection of the present invention.
