Description

Technical Field

[0001] The present application relates to the technical field of material taking, and in particular to a material taking device for injection molded parts. Background Art

[0002] Injection molded parts refer to plastic or rubber products of various shapes made from thermoplastics or thermosetting materials using plastic molding molds.

[0003] After the existing injection molded parts are formed in the mold, when the mold is opened to take out the material, due to the high temperature of the injection molded parts, in order to avoid safety hazards caused by scalding when manually taking out the material, most manufacturers currently use robot clamps to clamp out the injection molded parts; however, since the specifications and shapes of the produced injection molded parts are different, and some injection molded parts have uneven structures on their surfaces, the robot clamp is not convenient for adaptively clamping the injection molded parts of different shapes, and the injection molded parts are prone to detach from the clamp. Therefore, it can be seen that the existing injection molded parts taking structure is not easy to stably take out the material, and needs to be improved. Summary of the invention

[0004] In order to improve the stability of material removal for injection molded parts, the present application provides an injection molded part material removal device.

[0005] The present application provides an injection molded part material taking device, which adopts the following technical solution:

[0006] A device for taking out injection molded parts comprises a frame on which a clamping part, an adsorbing part and a moving assembly are arranged. The clamping part is used to clamp the injection molded part, the adsorbing part is used to adsorb the surface of the injection molded part, and the moving assembly is used to drive the clamping part and the adsorbing part to move relative to the frame so that the clamping part and the adsorbing part move in a direction of approaching or moving away.

[0007] By adopting the above-mentioned technical scheme, the present application sets up two methods for picking up injection molded parts, one of which is the traditional clamping method of the clamping part, and the other is the adsorption method of the adsorption part. The material picking is achieved by coordinating the clamping and adsorption. Even if the clamping part cannot stably clamp the injection molded part, the material picking stability can be improved by adsorbing the injection molded part, because the adsorption method of the adsorption part does not need to be limited to the shape of the injection molded part and the surface flatness of the injection molded part. In addition, the setting of the moving component can realize the free movement of the clamping part and the adsorption part, so that the clamping part and the adsorption part can be adaptively approached or moved away from the injection molded part to pick up the injection molded part and remove it from the mold.

[0008] Preferably, the frame includes a first bracket, a second bracket arranged on the first bracket, and a third bracket arranged on the second bracket, the length direction of the second bracket is perpendicular to the first bracket, the length direction of the third bracket is perpendicular to the second bracket, the clamping member and the adsorption member are arranged on the third bracket, the moving component is used to drive the second bracket to slide back and forth along the length direction of the first bracket, the moving component is also used to drive the third bracket to slide back and forth along the length direction of the second bracket, and the moving component is also used to drive the clamping member and the adsorption member to move back and forth along the length direction of the third bracket.

[0009] By adopting the above technical solution, the moving component can be used to drive the clamping member and / or the adsorbing member to move in multiple directions, thereby improving the freedom and flexibility of the movement of the clamping member and the adsorbing member and realizing multi-directional movement of the clamping member and the adsorbing member.

[0010] Preferably, a connecting block is provided on the third bracket, and the clamping member and the adsorption member are rotatably connected to the connecting block. The moving assembly is also used to drive the clamping member and the adsorption member to rotate relative to the connecting block and fix the rotation angle.

[0011] By adopting the above-mentioned technical solution, the moving component can also be used to drive the clamping part and the adsorption part to rotate relative to the frame, so as to achieve angle adjustment of the clamping part and the adsorption part relative to the frame, so that the clamping part and the adsorption part can be adaptively moved and rotated according to the position of the injection molded part, thereby further improving the freedom and flexibility of the movement of the clamping part and the adsorption part.

[0012] Preferably, the adsorption component includes a suction cup and an exhaust component, one end of the suction cup is provided with a suction port for fitting with the surface of the injection molded part, and the exhaust component is used to extract air at the suction port to form a negative pressure at the suction port; the adsorption component also includes a dust cover, which is arranged on the suction cup and is used to open and close the suction port.

[0013] By adopting the above technical scheme, when actually taking materials, the suction cup is driven to move by the moving component and the suction port of the suction cup is attached to the surface of the injection molded part. Then, the air at the suction port is extracted by the vacuum component to form a negative pressure at the suction port, so that the suction cup is adsorbed on the surface of the injection molded part. Then, the moving component drives the suction cup and the injection molded part adsorbed by it to move, so that the injection molded part is separated from the mold and the material is taken out. When there is no need to use the suction cup for adsorption and material taking, a dust cover can be set on the periphery of the suction port to reduce external dust from entering the suction port or even clogging the suction port, which affects the suction force of the suction cup on subsequent injection molded parts.

[0014] Preferably, the dust cover is rotatably connected to the periphery of the suction cup, and a connecting port for communicating with the suction port is opened on the side wall of the dust cover. A fixing piece is provided on the suction cup, and the fixing piece is used to fix the rotational position of the dust cover relative to the suction cup.

[0015] By adopting the above technical solution, the protective cover is sleeved on the outer periphery of the suction cup, so that the suction cup can be taken out and used at any time, and the convenience of taking out the dust cover is improved.

[0016] Preferably, the inner wall of the dust cover is provided with a first airbag and a second airbag connected to the first airbag, the fixing part includes a limit spring, the limit spring is in a deformed state, one end of the limit spring is connected to the suction cup, and the other end is pressed against the inner wall of the dust cover, and when the second airbag is inserted into the suction port, the first airbag is pressed against the outer surface of the suction cup due to the elastic force of the limit spring.

[0017] By adopting the above technical scheme, the dust cover is fixed in the rotational position relative to the suction cup by the elastic force of the limiting spring, and when the first airbag is pressed by the elastic force of the limiting spring, part of the gas in the first airbag will be squeezed into the second airbag connected thereto, thereby allowing the second airbag to be stably inserted into the suction port. The operation of inserting the second airbag into the suction port can not only clear the suction port, but also cooperate with the limiting spring to fix the position of the dust cover relative to the suction cup. When the suction port needs to be opened, the dust cover can be driven to move so that the limiting spring is further pressed, so that the suction cup surface releases the pressure on the first airbag, thereby allowing the first airbag to restore its initial degree of expansion, and finally allowing the second airbag to detach from the suction port and rotate to a position away from the suction port, thereby achieving the connection between the connecting port and the suction port.

[0018] Preferably, bristles are provided on the surface of the second airbag, and one end of the bristles away from the second airbag is used to abut against the inner wall of the suction port when the second airbag is inserted into the suction port.

[0019] By adopting the above technical solution, when the second airbag is inserted into the suction port, as part of the gas in the first airbag flows into the second airbag, the second airbag further expands, so that the end of the bristle fits the inner wall of the suction port with the help of the deformation of the second airbag, thereby further cleaning and unblocking the inner wall of the suction port.

[0020] Preferably, the inner wall of the dust cover is provided with a cooling layer for fitting with the surface of the suction cup.

[0021] By adopting the above technical solution, since the injection molded parts formed by injection molding are generally at a high temperature, when the suction cup is used to adsorb the surface of the high-temperature injection molded part, in order to reduce the problem of damage to the suction cup caused by the high temperature or a decrease in its service life, a cooling layer is specially provided on the inner wall of the dust cover, and the dust cover is arranged on the periphery of the suction cup, so that the suction cup can be cooled with the help of the cooling layer on the dust cover.

[0022] Preferably, the inner wall of the dust cover is provided with a third airbag and a fourth airbag which are interconnected, the third airbag is provided on the side wall of the dust cover near the connecting port, and the third airbag is provided circumferentially along the connecting port, the fourth airbag is attached to the side wall of the dust cover near the cooling layer, and when the connecting port is connected to the adsorption port, the third airbag is pressed against the outside of the dust cover, and part of the gas in the third airbag is squeezed into the fourth airbag, so that the fourth airbag is attached between the cooling layer and the outer surface of the suction cup.

[0023] By adopting the above technical solution, when it is necessary to use a suction cup to suck and pick up materials, the connecting port on the dust cover is connected to the suction port. At this time, the dust cover is clamped on the outer surface of the suction cup near the connecting port, and the third airbag is squeezed by the clamping force of the suction cup. Part of the gas stored therein will flow into the fourth airbag due to the squeezing, so that the fourth airbag is inflated and at the same time fits between the cooling layer and the outer surface of the suction cup, so that the temperature of the cooling layer can be transferred with the help of the inflated fourth airbag, thereby optimizing the cooling effect of the cooling layer on the surface of the suction cup.

[0024] Preferably, a docking ring for pressing the third airbag is provided on the surface of the suction cup, and a yielding arc surface is provided on the surface of the docking ring.

[0025] By adopting the above technical solution, the docking ring is used to strengthen the clamping force on the third airbag when the inner wall of the connecting port of the dust cover is clamped on the surface of the suction cup, so that the third airbag can be more easily pressed and deflated, so that part of the gas can be quickly transferred to the fourth airbag, and the setting of the yield arc surface can reduce the wear on the third airbag caused by the docking ring pressing against the third airbag.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. The clamping member and the adsorbing member can move in three directions relative to the frame, and can also rotate in three different directions to achieve free movement and rotation of the clamping member and the adsorbing member in multiple directions and angles;

[0028] 2. The present application also provides a dust cover for opening and closing the suction port on the periphery of the suction cup, and the dust cover has the function of cooling the outer surface of the suction cup and clearing the suction port to ensure the suction strength and stability of the suction cup on the injection molded part.

[0036] Reference Figure 1The frame 1 includes a first bracket 11, a second bracket 12 and a third bracket 13.

Specifically, the rotation angle of the first steering block 15 is fixed by a bolt passing through the connecting block 14 and pressing against the side wall of the first steering block 15, and the rotation angle of the second steering block 16 is fixed by another bolt passing through the first steering block 15 and pressing against the side wall of the second steering block 16.

[0040] Reference Figure 3 The number of suction cups 31 of the present application is 2, and a dust cover 5 is provided on the outside of each suction cup 31. A fixing part 6 is provided on the outer surface of the suction cup 31. The fixing part 6 can specifically be a limit spring 61 and a telescopic sleeve 62 sleeved on the outside of the limit spring 61. The telescopic direction of the telescopic sleeve 62 is parallel to the telescopic direction of the limit spring 61. One end of the telescopic sleeve 62 is fixed to the outer surface of the suction cup 31, and the other end is in contact with the inner wall of the dust cover 5 with the help of the elastic force of the limit spring 61.

[0041] Reference Figure 3 The dust cover 5 is rotatably connected to the outer periphery of the suction cup 31, and a connecting port 51 is provided on the side wall of the dust cover 5. The diameter of the connecting port 51 is larger than that of the suction port 311. When the dust cover 5 is rotated to a state where the connecting port 51 is connected to the suction port 311, that is, Figure 3 In the state shown, the inner wall of the dust cover 5 near the connecting port 51 is clamped on the outer surface of the suction cup 31, and the limit spring 61 is in an undeformed state. At this time, the suction cup 31 can be used to absorb the injection molded part to achieve material removal. When there is no need to remove the material, the dust cover 5 can be pulled toward the direction close to the suction port 311 (i.e. Figure 3 The dust cover 5 is then rotated in the direction of arrow C in the figure to move the side wall of the dust cover 5 away from the connecting port 51 to the periphery of the suction port 311, thereby closing the suction port 311 and reducing the blockage of the suction port 311 by dust and impurities in the external environment. Finally, the pulling on the dust cover 5 is released, and the limit spring 61 will drive the dust cover 5 to move in the direction away from the suction port 311 again (i.e., move in the direction opposite to the arrow B) under the action of the elastic force, so that the inner wall of the dust cover 5 fits the end wall of the suction port 311 of the suction cup 31.

[0042] Reference Figure 3 The inner wall of the dust cover 5 near the connecting port 51 is provided with a third airbag 52, which is connected to a fourth airbag 53. The third airbag 52 and the fourth airbag 53 are respectively filled with some air in advance. At this time, the third airbag 52 and the fourth airbag 53 are in an initial state. The inner wall of the dust cover 5 near the fourth airbag 53 is provided with a cooling layer 55, which is specifically a cooling cavity filled with coolant.

[0043] Reference Figure 3The outer surface of the suction cup 31 is fixedly connected to a docking ring 312, and the surface of the docking ring 312 is provided with a yielding cambered surface 313, and the outer diameter of the docking ring 312 is larger than the inner diameter of the connecting port 51. At the same time, when the outer diameter of the docking ring 312 is larger than the third air bag 52 and is in the initial state, the inner diameter enclosed by the third air bag 52 is smaller than the outer diameter of the docking ring 312; therefore, when the dust cover 5 is clamped to the outer periphery of the suction cup 31 under the elastic force of the limit spring 61, the third air bag 52 on the inner wall of the connecting port 51 contacts and is clamped to the outer periphery of the docking ring 312, and the docking ring 312 will squeeze the third air bag 52, so that part of the gas in the third air bag 52 flows into the fourth air bag 53, causing the fourth air bag 53 to swell, and the side wall of the inflated fourth air bag 53 will fit between the inner wall of the dust cover 5 and the outer surface of the suction cup 31, so as to cooperate with the cooling layer 55 through the fourth air bag 53 to achieve cooling of the suction cup 31.

[0044] Reference Figure 3 The inner wall of the dust cover 5 is also provided with a first air bag 56 and a second air bag 57 which are interconnected. The first air bag 56 and the second air bag 57 are respectively pre-filled with some air. When the first air bag 56 and the second air bag 57 are at a position away from the suction port 311, the first air bag 56 and the second air bag 57 are in an initial state; and when the dust cover 5 rotates in the direction indicated by the arrow C until the first air bag 56 contacts the end wall of the suction port 311 of the suction cup 31, the second air bag 57 is just opposite to the suction port 311. If the hand releases the pull on the dust cover 5 at this time, the limit spring 61 will use the elastic force to drive the dust cover 5 in the direction opposite to the arrow B Move, and then make the end wall of the suction cup 31 at the suction port 311 press against the first air bag 56, so that part of the gas in the first air bag 56 flows into the second air bag 57, so that the second air bag 57 is inflated and inserted into the suction port 311, so as to achieve the unblocking of the suction port 311; in addition, the outer surface of the second air bag 57 is also provided with bristles 58, when the inflated second air bag 57 is inserted into the suction port 311, the end of the bristle 58 will be against the inner wall of the suction port 311, so as to achieve the scraping and cleaning of the inner wall of the suction port 311 when the second air bag 57 is detached from or inserted into the suction port 311, so as to further optimize the unblocking effect of the suction port 311.

[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
