Description

Technical Field

[0001] This utility model relates to the field of production equipment technology, and in particular to an automatic aluminum sheet feeding device for injection molding production. Background Technology

[0002] Most existing plastic product manufacturing processes require a double injection molding (secondary injection molding) operation. For example... Figure 1 As shown in the diagram, an aluminum sheet 10 is used to embed in a product during injection molding. The aluminum sheet 10 has holes 11. The injection molding process typically involves the following steps: After the injection molding machine completes the injection of the semi-finished product, it opens the mold and automatically ejects the semi-finished product. Then, a worker manually feeds the aluminum sheet 10 to the corresponding position on the injection molding machine. Subsequently, the injection molding machine automatically retracts the semi-finished product into the mold for molding. After molding, the worker removes the finished injection-molded product from the injection molding machine, thus completing the unloading of the finished product. This existing production method relies on manual feeding of the aluminum sheet 10 and unloading of the finished product, resulting in a low degree of automation. Due to the slow efficiency of manual operation, the overall production efficiency is low. Furthermore, manual operation is prone to accidents such as crushing injuries, posing certain safety hazards and hindering large-scale production applications. Utility Model Content

To this end, this invention proposes an automatic aluminum sheet feeding device for injection molding production, which can mechanically feed aluminum sheets and unload injection-molded products, improving the current situation of manual feeding and unloading, enhancing automation, increasing production efficiency, and facilitating large-scale production applications.

[0004] The automatic aluminum sheet feeding device for injection molding production according to an embodiment of the present invention includes a machine base, a material preparation component, a positioning mechanism, a transfer mechanism, and a mechanical fixture.

The first picking mechanism can pick up the aluminum sheets on the transfer base, and the second picking mechanism can pick up the injection-molded finished products in the injection molding machine.

[0005] The automatic aluminum sheet feeding device for injection molding production according to the embodiments of this utility model has at least the following beneficial effects: In use, multiple aluminum sheets are stacked in the material trough of the material preparation component, and then the material preparation component is installed on the machine table. The aluminum sheets in the material trough are obtained by the transfer mechanism and transported and placed on the transfer material seat of the positioning mechanism. The positioning mechanism is used to position the aluminum sheets placed thereon. The mechanical fixture is connected to the robot and driven by the robot. The robot moves the mechanical fixture to dock with the positioning mechanism. The first material picking mechanism obtains the aluminum sheets on the transfer material seat. After the injection molding machine automatically ejects the semi-finished product, the robot drives the mechanical fixture to move to the corresponding position of the injection molding machine, so that the first material picking mechanism feeds the aluminum sheet to the corresponding position of the injection molding machine. Then the injection molding machine automatically retracts the semi-finished product into the mold for secondary injection molding. After the secondary injection molding is completed, the robot drives the mechanical fixture to move, so that the second material picking mechanism obtains the injection molded finished product in the injection molding machine, thereby realizing the unloading of the injection molded finished product.

[0036] Reference Figure 2 , Figure 4 , Figure 5 and Figure 6 An automatic aluminum sheet feeding device for injection molding production includes a machine base 100, a material preparation assembly 200, a positioning mechanism 300, a transfer mechanism 400, and a mechanical fixture 500. The material preparation assembly 200 is detachably mounted on the machine base 100 and has a material trough 201 for stacking aluminum sheets 10. The positioning mechanism 300 is mounted on the machine base 100 and has a transfer base 310 for placing the aluminum sheets 10. The positioning mechanism 300 can position the aluminum sheets 10 on the transfer base 310. Positioning is performed by a transfer mechanism 400 located on the machine base 100. The transfer mechanism 400 can pick up the aluminum sheet 10 in the material trough 201 and transport it to the transfer material seat 310. The mechanical fixture 500 is used to connect with the robot and can be driven by the robot. The mechanical fixture 500 is equipped with a first picking mechanism 510 and a second picking mechanism 520. The first picking mechanism 510 can pick up the aluminum sheet 10 on the transfer material seat 310, and the second picking mechanism 520 can pick up the injection molded product in the injection molding machine.

[0037] Understandably, such as Figure 2 , Figure 4 , Figure 5 and Figure 6As shown, the material preparation assembly 200 and the positioning mechanism 300 are located on the front side of the machine base 100 and are spaced apart in the left-right direction. The transfer mechanism 400 is located on the rear side of the machine base 100 and can move between the material preparation assembly 200 and the positioning mechanism 300. In use, multiple aluminum sheets 10 are stacked in the material trough 201 of the material preparation assembly 200. Then, the material preparation assembly 200 is installed on the machine base 100. The transfer mechanism 400 picks up the aluminum sheets 10 from the material trough 201 and transports them to the transfer material seat 310 of the positioning mechanism 300. The positioning mechanism 300 positions the aluminum sheets 10 placed on it. The mechanical fixture 500 is connected to a robot (not shown in the figure) and is driven by the robot. The robot moves the mechanical fixture 500 to dock with the positioning mechanism 300. The first material handling mechanism 510 picks up the aluminum sheet 10 from the transfer material holder 310. After the injection molding machine automatically ejects the semi-finished product, the robot arm drives the mechanical fixture 500 to move to the corresponding position on the injection molding machine, so that the first material handling mechanism 510 loads the aluminum sheet 10 to the corresponding position on the injection molding machine. Then, the injection molding machine automatically retracts the semi-finished product into the mold for secondary injection molding. After secondary injection molding is completed, the robot arm drives the mechanical fixture 500 to move, so that the second material handling mechanism 520 picks up the injection-molded finished product from the injection molding machine, thereby realizing the unloading of the injection-molded finished product. This utility model has a simple and reasonable structure, which can mechanically load the aluminum sheet 10 and unload the injection-molded finished product, improving the current situation of manual loading and unloading, which is conducive to improving the degree of automation, increasing production efficiency, and facilitating large-scale production applications.

[0038] In practical applications, the specific structures of the material preparation component 200, positioning mechanism 300, transfer mechanism 400, and mechanical fixture 500 can be set according to actual usage needs, and will not be detailed here, but will be explained in detail below; since the specific composition and working principle of the robot mentioned in the embodiments of this utility model are known to those skilled in the art, they will not be described in detail here.

[0039] In some embodiments, the material preparation assembly 200 includes a base plate 210 and a limiting plate 220 disposed on the base plate 210. Two limiting plates 220 are provided for each material trough 201. The two limiting plates 220 are spaced apart and define the discharge trough 201 between them, so that the side and top of the material trough 201 have openings.

[0040] Understandably, such as Figure 2 and Figure 4As shown, each material preparation assembly 200 has four material troughs 201, thus each material preparation assembly 200 includes eight limiting plates 220. A material trough 201 is defined between every two limiting plates 220, and the material trough 201 has openings on both its side and top. In use, aluminum sheets 10 can be placed one by one through the top opening of the material trough 201, so that multiple aluminum sheets 10 are stacked vertically in the material trough 201. The side openings of the material trough 201 facilitate adjustment and observation of the aluminum sheets 10 in the material trough 201, making material preparation convenient. In practical applications, in addition to the above structure, a cylindrical component can also be provided on the base plate 210, with the material trough 201 located within the cylindrical component. The number of limiting plates 220 can be varied according to the arrangement of the material troughs 201.

[0041] In some embodiments, the material preparation assembly 200 is detachably placed on the machine base 100, the base plate 210 is in contact with the machine base 100, one of the base plate 210 and the machine base 100 is provided with a first positioning post 110, and the other is provided with a first positioning hole 202 that cooperates with the first positioning post 110.

[0042] Understandably, such as Figure 2 and Figure 4 As shown, the first positioning post 110 is located on the machine base 100, and the first positioning hole 202 is correspondingly located on the base plate 210. There are two material preparation components 200, which are spaced apart in the left and right direction. After the aluminum sheet 10 of one material preparation component 200 is loaded, the transfer mechanism 400 can immediately pick up the material from the other material preparation component 200 to ensure continuous operation of the equipment. When the aluminum sheet 10 of the material preparation component 200 is loaded, the material preparation component 200 can be directly lifted off the machine base 100 to facilitate the subsequent replenishment of aluminum sheet 10 into the material trough 201. The material preparation component 200 with the aluminum sheet 10 loaded can be directly placed on the machine base 100 so that the base plate 210 and the machine base 100 are in contact. The first positioning post 110 and the first positioning hole 202 are inserted and cooperated to realize the positioning of the material preparation component 200, and can reduce the possibility of the material preparation component 200 shifting during use, making it easy to use.

[0043] In practical applications, the first positioning post 110 can also be set on the base plate 210, and the first positioning hole 202 is set on the machine tool 100 accordingly. The number of material preparation components 200 can also be changed according to actual usage needs. In addition, the detachable connection between the material preparation component 200 and the machine tool 100 can also be achieved through threaded structure, snap-fit ​​structure, etc., which can be set according to actual usage needs.

[0044] Furthermore, a handle 211 is provided on the base plate 210. It is understandable that, as... Figure 2 and Figure 4As shown, handles 211 are provided on both the front and rear sides of the base plate 210. By providing handles 211, users can easily lift the material preparation component 200 from the machine base 100, making it easy to separate from the machine base 100 and to transport it for convenient use. In actual applications, the specific structure of the handles 211 can be set according to the actual usage requirements.

[0045] In some embodiments, the base plate 210 is provided with a through hole 203 on the lower side of the material trough 201, and the machine base 100 is provided with a detection element 120 corresponding to the through hole 203. The detection element 120 can detect the remaining status of aluminum sheet 10 in the material trough 201 through the through hole 203.

[0046] Understandably, such as Figure 2 , Figure 3 and Figure 4 As shown, the base plate 210 has through holes 203 on the underside of each material trough 201. The machine tool 100 is equipped with a detection element 120 corresponding to each through hole 203. During use, the detection element 120 detects the remaining aluminum sheet 10 in the material trough 201 through the through holes 203, thus determining whether aluminum sheet 10 is present in the trough 201. After the aluminum sheet 10 is completely fed, it can promptly remind the user to replenish the aluminum sheet 10, facilitating use. In practical applications, the detection element 120 can be a photoelectric sensor, proximity switch, etc., and can be configured according to actual usage requirements.

[0047] In some embodiments, the transfer mechanism 400 includes a horizontal moving component 410, a lifting moving component 420, and a suction cup component 430 for picking up aluminum sheets 10. The horizontal moving component 410 is disposed on the machine base 100 and connected to the lifting moving component 420, and can drive the lifting moving component 420 to move horizontally between the material preparation component 200 and the positioning mechanism 300. The lifting moving component 420 is connected to the suction cup component 430 and can drive the suction cup component 430 to move up and down.

[0048] Understandably, such as Figure 2 and Figure 3As shown, the horizontal moving component 410 is positioned on the machine base 100 along the left-right direction and connected to the lifting moving component 420. The lifting moving component 420 is connected to the suction cup component 430, which consists of multiple suction cups. In use, the horizontal moving component 410 drives the lifting moving component 420 to move horizontally left and right between the material preparation component 200 and the positioning mechanism 300. The lifting moving component 420 drives the suction cup component 430 to move left and right together. When it moves to the corresponding position on the material preparation component 200, the lifting moving component 420 drives the suction cup component 430 to move and descend. Then, the suction cup component 430 picks up the aluminum sheet 10 in the material trough 201. The lifting moving component 420 drives the suction cup component 430 to move upward and reset, thereby obtaining the aluminum sheet 10 from the material trough 201. 0; Subsequently, the horizontal moving component 410 drives the lifting moving component 420 to move to the corresponding position of the positioning mechanism 300. The lifting moving component 420 then drives the suction cup component 430 to move and descend, so that the suction cup component 430 places the aluminum sheet 10 it has picked up on the transfer material seat 310 and then releases the suction of the aluminum sheet 10. The lifting moving component 420 drives the suction cup component 430 to move upward and reset, so as to realize the transfer of the aluminum sheet 10 in the material trough 201 to the transfer material seat 310 of the positioning mechanism 300. The above structure is simple and reasonable and easy to use.

[0049] In practical applications, the horizontal moving component 410 can be a combination of a linear motor and a motion platform, or a combination of a motor and a lead screw transmission structure to achieve horizontal movement. The lifting moving component 420 can be driven to move up and down by a cylinder, hydraulic cylinder, or other actuator, or can be set with reference to the structure of the horizontal moving component 410. In addition to the above structures, the transfer mechanism 400 can also be composed of a multi-axis motion assembly and a clamping component. The clamping component can be a pneumatic gripper, a mechanical gripper, etc. The multi-axis motion assembly drives the clamping component to translate and lift, and then the clamping component clamps the aluminum sheet 10, thereby realizing the acquisition and transportation of the aluminum sheet 10. The specific structure of the transfer mechanism 400 can also be changed according to the actual use needs. Since the specific structure of the suction cup component 430 of this utility model embodiment is known to those skilled in the art, it will not be described in detail here.

[0050] In some embodiments, the positioning mechanism 300 includes a positioning block 320 and a positioning driver 330. The positioning block 320 is disposed on the side of the transfer material holder 310. The positioning driver 330 is connected to a positioning clamp 331, which can drive the positioning clamp 331 to move and push the aluminum sheet 10 on the transfer material holder 310 to abut against the positioning block 320.

[0051] Understandably, such as Figure 5As shown, each transfer base 310 is provided with two positioning blocks 320. One positioning block 320 is located on the rear side of the transfer base 310, and the other is located on the left or right side of the transfer base 310. The positioning driver 330 drives the positioning clamping block 331 connected to it. The positioning clamping block 331 is located on the diagonal side of the two positioning blocks 320 and has a "V" shaped notch. In use, the positioning driver 330 drives the positioning clamping block 331 to move closer to the aluminum sheet 10 on the transfer base 310, so that the positioning clamping block 331 pushes the aluminum sheet 10 on the transfer base 310 to abut against the two corresponding positioning blocks 320, thereby positioning and adjusting its placement position in the front-back direction and left-right direction, so as to better position the aluminum sheet 10 and facilitate its use. In practical applications, the specific structure and quantity of positioning block 320 and positioning clamp block 331 can be set according to actual usage needs. In addition to the above structure, a positioning groove that matches the shape of aluminum sheet 10 can be provided on the transfer base 310, and a guide structure can be provided on the side of the transfer base 310 to guide the aluminum sheet 10 into the positioning groove for positioning.

[0052] Furthermore, the transfer material holder 310 is provided with a second positioning pin 311, which is distributed and arranged corresponding to the holes 11 of the aluminum sheet 10 and can be clearance-fitted with the holes 11 of the aluminum sheet 10. It is understood that, as... Figure 1 and Figure 5 As shown, each aluminum sheet 10 has two holes 11, therefore, two corresponding second positioning pins 311 are also provided on each transfer base 310. In use, the transfer mechanism 400 places the aluminum sheet 10 on the transfer base 310, and the second positioning pins 311 pass through the corresponding holes 11 with a clearance fit, thereby initially positioning the aluminum sheet 10 on the transfer base 310, limiting its approximate position and preventing excessive displacement. Subsequently, the positioning block 320 and the positioning clamping block 331 cooperate for secondary pushing and positioning, which helps ensure positioning accuracy and facilitates use. In practical applications, the specific structure, number, and distribution of the second positioning pins 311 can be set according to actual usage needs.

[0053] In some embodiments, the first material handling mechanism 510 includes a material handling seat 511, a material unloading driver 512, and a pusher 513. The material handling seat 511 and the material unloading driver 512 are both fixedly mounted on the mechanical fixture 500. The lower side of the material handling seat 511 is provided with an adsorption structure 501 for picking up aluminum sheets 10. The pusher 513 is movably inserted through the material handling seat 511 and connected to the material unloading driver 512. The material unloading driver 512 is used to drive the pusher 513 to move relative to the material handling seat 511, so that the pusher 513 can extend out of the lower side of the material handling seat 511 to push the aluminum sheets 10 picked up by the adsorption structure 501.

[0054] Understandably, such as Figure 2 , Figure 6 and Figure 7 As shown, the unloading driver 512 and the picking seat 511 are both fixedly mounted on the mechanical fixture 500. When the robot drives the mechanical fixture 500 to move, it drives the unloading driver 512 and the picking seat 511 to move together. The picking seat 511 is provided with an adsorption structure 501 for picking up the aluminum sheet 10. The adsorption structure 501 can be a suction cup or a negative pressure hole, etc., which can generate suction to pick up the aluminum sheet 10. The push pin 513 can move up and down and is inserted into the picking seat 511. The unloading driver 512 is driven to connect with the push pin 513 and is used to drive the push pin 513 to move up and down relative to the picking seat 511. In use, when the first material handling mechanism 510 moves to the corresponding position of the positioning mechanism 300, the lower side of the material handling seat 511 contacts and adheres to the aluminum sheet 10 of the transfer material seat 310. Then, the adsorption structure 501 is used to pick up the aluminum sheet 10 on the transfer material seat 310. The robot arm drives the mechanical fixture 500 to move as a whole, so that the first material handling mechanism 510 moves away from the upper side of the positioning mechanism 300 to pick up the aluminum sheet 10 on the transfer material seat 310. When the first material handling mechanism 510 moves to the corresponding material feeding position of the injection molding machine, the unloading driver 512 drives the pusher 513 to move relative to the material handling seat 511, so as to push the aluminum sheet 10 picked up by the adsorption structure 501 to the corresponding position in the injection molding machine, thereby realizing the feeding of the aluminum sheet 10. Its structure is simple and easy to use. In practical applications, in addition to the above methods, the first material handling mechanism 510 can also pick up and unload the aluminum sheet 10 by clamping, such as using pneumatic grippers, mechanical grippers, etc. The positioning driver 330 and unloading driver 512 in this utility model can be common drivers such as cylinders, hydraulic cylinders, electric push rods, etc., and can be set according to actual use needs.

[0055] In some embodiments, one of the mechanical fixture 500 and the positioning mechanism 300 is provided with a second positioning post 530, and the other is provided with a corresponding second positioning hole 301. When the material pick-up seat 511 picks up the aluminum sheet 10 on the transfer material seat 310 through the adsorption structure 501, the second positioning post 530 cooperates with the second positioning hole 301.

[0056] Understandably, such as Figure 2 , Figure 5 , Figure 6 and Figure 7As shown, the second positioning post 530 is disposed on the mechanical fixture 500, and the second positioning hole 301 is correspondingly disposed on the positioning mechanism 300. When the material picking seat 511 picks up the aluminum sheet 10 on the transfer material seat 310 through the adsorption structure 501, the second positioning post 530 cooperates with the second positioning hole 301 to facilitate the positioning and docking of the first material picking mechanism 510 and the positioning mechanism 300, ensuring the accuracy of material picking. In actual application, the second positioning post 530 is disposed on the positioning mechanism 300, and the second positioning hole 301 is correspondingly disposed on the mechanical fixture 500. The specific settings can be adjusted according to actual usage requirements.

[0057] In some embodiments, the material taking seat 511 is provided with a first positioning pin 514 and an elastic member 515. The first positioning pin 514 is movable up and down in the material taking seat 511 and is distributed corresponding to the hole positions 11 of the aluminum sheet 10. The elastic member 515 acts on the first positioning pin 514, and the first positioning pin 514 can extend out of the lower side of the material taking seat 511 and be inserted into the hole position 11 of the aluminum sheet 10 under the action of the elastic member 515. The first positioning pin 514 can retract into the material taking seat 511.

[0058] Understandably, such as Figure 6 and Figure 7 As shown, each material picker 511 is provided with two first positioning pins 514. The two first positioning pins 514 are distributed corresponding to the two holes 11 of the aluminum sheet 10. An elastic element 515 is provided on the upper side of the first positioning pin 514. The elastic element 515 acts on the first positioning pin 514, causing it to have a downward tendency, so that the first positioning pin 514 extends out of the lower side of the material picker 511. During material handling, the material handling seat 511 contacts and adheres to the aluminum sheet 10 on the transfer material seat 310. The first positioning pin 514 retracts into the material handling seat 511 under the downward pressure, overcoming the force of the elastic element 515. After material handling is completed and the material handling seat 511 leaves the transfer material seat 310, the first positioning pin 514 moves downward under the action of the elastic element 515, extending out from the lower side of the material handling seat 511 and inserting into the hole 11 of the aluminum sheet 10. Thus, during the handling of the aluminum sheet 10, the first positioning pin 514 can position the aluminum sheet 10 on the material handling seat 511, which helps to limit its movement, reduce the possibility of its deviation, and facilitate use. In practical applications, the elastic element 515 can be a spring or other elastic component, and the specific structure and connection method of the first positioning pin 514 can be set according to actual usage needs.

[0059] In some embodiments, the second material handling mechanism 520 includes a plurality of suction cups 521 for picking up injection-molded finished products. It is understood that, as Figure 3 and Figure 6As shown, the second material handling mechanism 520 includes multiple suction cups 521, which are spaced apart and arranged on the mechanical fixture 500. In use, the second material handling mechanism 520 uses the multiple suction cups 521 to pick up the molded product from the injection molding machine. Its simple structure helps reduce the possibility of damaging the molded product and is easy to use. In practical applications, in addition to obtaining the molded product through suction, it can also be obtained through clamping or a combination of clamping and suction, depending on the specific needs of the application.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
