It should also be understood that terms defined in general dictionaries, for example, should be interpreted as having meanings consistent with their meanings in the context of the relevant technology, and should not be interpreted in an idealized or extremely formal sense, unless explicitly defined as such herein.

[0030] The technologies, methods and equipment known to ordinary technicians in the relevant fields may not be discussed in detail, but in appropriate cases, the technologies, methods and equipment should be regarded as part of the specification. As mentioned in the above background technology, in the process of producing insert products, the injection molding machine needs to put the insert into the mold, and after the mold is closed for injection molding, the molded product is taken out of the mold. In order to improve efficiency and protect the safety of production line personnel, the insertion of the insert and the removal of the molded product need to be completed by the insert placement mechanism and product removal mechanism of the injection molding machine. Although the mechanical removal of the insert and the safety of the production line personnel are achieved through the existing technology, another set of insert placement mechanism is required to cooperate with the insertion of the insert, thereby increasing the cost of the equipment and the space occupied by the equipment; at the same time, the insertion of the insert and the removal of the molded product are divided into two steps, which will undoubtedly increase the production time and affect the production efficiency. Based on this, the inventor of the present application provides a pick-and-place device and an injection molding machine for an injection molding machine in one or more embodiments. The pick-and-place device realizes the integration of the operation of insert insertion and molded product removal by installing both the insert installation mechanism and the pick-up mechanism on the end of the mechanical arm, further improving the production efficiency. It is believed that it can solve one or more problems in the prior art.

[0031] In view of the above-mentioned technical problems, the utility model provides a device for taking and placing parts of an injection molding machine, such as Figure 1-Figure 3 As shown, it includes: a robot arm 1; an insert installation mechanism 2, the insert installation mechanism 2 includes an ejection assembly and an insert base plate 3, the ejection assembly is installed on the end of the robot arm 1, the ejection assembly is connected to the insert base plate 3 for ejecting the insert adsorbed on the insert base plate 3 into the first mold 4 of the injection molding machine; and a pickup mechanism 5, the pickup mechanism 5 includes a flipping assembly, an adsorption plate 6 and a product suction head 7, the flipping assembly is connected to the end of the robot arm 1, the adsorption plate 6 is connected to the flipping assembly, and can be flipped between a horizontal state and a vertical state by the flipping assembly, and the product suction head 7 is arranged on the adsorption plate 6 for adsorbing the molded product in the second mold 19.

[0032] Specifically, after the insert base plate 3 absorbs the insert, the robot 1 moves and moves its end to between the first mold 4 and the second mold 19 of the injection molding machine, the insert installation mechanism 2 is placed on one side of the first mold 4, and the pick-up mechanism 5 is in a vertical state and placed on one side of the second mold 19. The insert absorbed on the insert base plate 3 is pushed into the first mold 4 by the ejection assembly. After the insert is in place in the first mold 4, the insert base plate 3 is released from adsorption, and the robot 1 moves to the second mold 19. The product suction head 7 abuts against the molded product in the second mold 19 and adsorbs the molded product on the adsorption plate 6. The robot 1 moves so that its end moves out from between the first mold 4 and the second mold 19, and the first mold 4 and the second mold 19 are molded together for injection molding. In the process of the end of the robot 1 moving out from between the first mold 4 and the second mold 19, the adsorption plate 6 is flipped to a horizontal state by the flip assembly. After the end of the robot 1 moves to the top of the molded product storage box, the product suction head 7 is released from adsorption, and the molded product falls into the storage box. Then, the adsorption plate 6 is flipped to a vertical state by the flipping mechanism, and the insert bottom plate 3 adsorbs the insert to produce the next product. The above process is repeated to form an assembly line production of molded products.

[0033] Compared with the prior art, the present application provides a picking and placing device for an injection molding machine, in which the insert installation mechanism 2 and the picking mechanism 5 are both installed on the end of the robot arm 1, thereby realizing the integration of insert placement and molded product removal operations, saving production time and further improving production efficiency.

[0034] In some embodiments, Figure 1 As shown, the insert bottom plate 3 is provided with negative pressure suction holes 8 or magnetic suction 9 for adsorbing the insert. The insert bottom plate 3 is adsorbed by the negative pressure suction holes 8 or magnetic suction 9. Specifically, when the negative pressure suction holes 8 are used to adsorb the insert, the negative pressure suction holes 8 are connected to a suction mechanism to evacuate the negative pressure suction holes 8, so that negative pressure is formed in the negative pressure suction holes 8, thereby adsorbing the insert on the insert bottom plate 3; when the insert is made of metal material, the magnetic suction 9 can also be used to adsorb the insert. Specifically, the magnetic suction 9 can be electromagnetic suction 9, and the adsorption and release of the magnetic suction 9 can be controlled by powering on and off.

[0035] In some embodiments, Figure 1 As shown, the ejector assembly includes an ejector plate 10 and a cylinder 11. The ejector plate 10 is connected to the end of the robot arm 1. The cylinder 11 is installed on the ejector plate 10. The driving end of the cylinder 11 is connected to the insert base plate 3. The ejector assembly is connected to the end of the robot arm 1 through the ejector plate 10. The insert base plate 3 is pushed to move by the cylinder 11, and the insert adsorbed on the insert base plate 3 can be ejected into the first mold 4. Specifically, the ejector plate 10 can be made of a stainless steel plate.

[0036] In some embodiments, Figure 1 and Figure 4As shown, the ejection assembly further includes a cylindrical slideway 12 and a slide bar 13. The cylindrical slideway 12 is disposed on the ejection plate 10. The slide bar 13 is slidably disposed in the cylindrical slideway 12, and one end of the slide bar 13 is connected to the insert base plate 3. The cylindrical slideway 12 and the slide bar 13 ensure that the insert base plate 3 moves stably when the cylinder 11 drives the insert base plate 3 to move, thereby avoiding the problem of deflection of the insert base plate 3 during movement. Furthermore, the cylindrical slideway 12 may include multiple cylindrical slideways 12, which are evenly distributed on the ejection plate 10, and a slide bar 13 is disposed in each cylindrical slideway 12.

[0037] In some embodiments, Figure 1 As shown, the ejector plate 10 is connected to the end of the robot arm 1 through the adapter plate 14. The adapter plate 14 facilitates the disassembly and assembly of the insert mounting mechanism 2 and the end of the robot arm 1. Specifically, the insert base plate 3, the cylinder 11, and the ejector plate 10 are first connected into a whole to form the insert mounting mechanism 2, and then the ejector plate 10 is connected to the adapter plate 14 by bolts. When the insert mounting mechanism 2 needs to be repaired and replaced, the ejector plate 10 can be directly removed from the adapter plate 14. Furthermore, the adapter plate 14 can also be made of stainless steel, and the specifications and dimensions of the adapter plate 14 must be able to bear the load of the insert mounting mechanism 2 and the insert.

[0038] In some embodiments, Figure 1 As shown, the flip assembly includes a fixed plate 15, a rotary cylinder 16, and a fixed block 17. The fixed plate 15 is connected to the end of the robot arm 1, the rotary cylinder 16 is installed on the fixed plate 15, and the adsorption plate 6 is connected to the rotary part of the rotary cylinder 16 through the fixed block 17. The connection between the rotary cylinder 16 and the end of the robot arm 1 is realized by the fixed plate 15, and the connection between the rotary part of the rotary cylinder 16 and the adsorption plate 6 is realized by the fixed block 17. Specifically, the fixed plate 15 and the fixed block 17 can be made of stainless steel.

[0039] In some embodiments, Figure 1 As shown, the product suction heads 7 include a plurality of product suction heads 7, through which the formed product can be firmly adsorbed on the adsorption plate 6, thereby avoiding the problem that the formed product falls off the adsorption plate 6 and affects production.

[0040] In some embodiments, Figure 1As shown, the pickup mechanism 5 also includes a waste suction head 18, which is arranged on the edge of the adsorption plate 6 to adsorb the waste in the second mold 19. The waste suction head 18 arranged on the edge of the adsorption plate 6 can adsorb the waste generated at the edge of the finished product during the mold closing process together with the finished product on the adsorption plate 6. After the end of the robot arm 1 moves out from between the first mold 4 and the second mold 19, the flip assembly flips the adsorption plate 6 to a horizontal state, places the adsorption plate 6 above the waste storage box, releases the adsorption of the waste suction head 18, and the waste falls into the waste storage box. Then, the adsorption plate 6 is placed above the molded product storage box by the robot arm 1, and the product suction head 7 is released from adsorption, and the molded product falls into the storage box. Through the cooperation of the waste suction head 18 and the product suction head 7, the automatic separation of the molded product and the waste is realized, further saving production time.

[0041] In some embodiments, Figure 1 As shown, there are multiple negative pressure suction holes 8 or magnetic suction holes 9. Multiple negative pressure suction holes 8 or multiple magnetic suction holes 9 ensure that the insert can be firmly adsorbed on the insert bottom plate 3, avoiding the problem of the insert falling during the adsorption process and affecting production.

[0042] In addition, the utility model also provides an injection molding machine, including a first mold 4 and a second mold 19 , and a pick-and-place device of the injection molding machine that can be arranged between the first mold 4 and the second mold 19 .

[0043] In summary, compared with the prior art, the present invention provides a pick-and-place device for an injection molding machine and an injection molding machine, wherein the pick-and-place device is installed on the end of a robot arm 1 through an insert installation mechanism 2 and a pick-up mechanism 5, thereby realizing the integration of insert placement and molded product removal, saving production time and further improving production efficiency; the insert base plate 3 is adsorbed on the insert through negative pressure suction holes 8 or magnetic suction 9; the insert adsorbed on the insert base plate 3 can be pushed into the first mold 4 through the cylinder 11; the adsorption plate 6 is flipped through the rotary cylinder 16; and the automatic separation of molded products and waste is realized through the cooperation of the waste suction head 18 and the product suction head 7, thereby further saving production time.
