[0044] like Figure 1In one embodiment of this application, an automatic material handling device for an injection molding machine is provided, comprising: a first frame 10, a second frame 20, a wire separating assembly 30, a wire placing assembly 40, and a wire picking assembly 50. The second frame 20 is connected to the first frame 10. The wire separating assembly 30 is disposed on the first frame 10 and is used to move the wire to a preset position. The wire placing assembly 40 is disposed on the second frame 20 and is movable relative to the second frame 20 along a first direction. The wire placing assembly 40 is used to grab the wire at the preset position and place the grabbed wire into the mold of the horizontal injection molding machine. The wire picking assembly 50 is disposed on the second frame 20 and is movable relative to the second frame 20 along the first direction. The wire picking assembly 50 is used to grab the injection-molded wire from the mold and place the injection-molded wire into a preset container.

[0045] The automatic material handling equipment for injection molding machines in this application is mainly used in the injection molding of artificial flowers. The first orientation in this application is as follows: Figure 1 The X-axis direction is used. In operation, the wire to be injection molded is placed into the wire separating assembly 30. The wire separating assembly 30 moves the attracted wire to a preset position. Then, the wire placing assembly 40 picks up the wire from the preset position and places it into the mold of the horizontal injection molding machine. After the mold has formed the injection, the wire removing assembly 50 places the molded wire into a preset container, thus completing one cycle. The entire process is highly automated, requiring minimal manual handling of the wire, greatly reducing labor costs and safety hazards caused by manual operation.

[0046] In some embodiments, such as Figure 2 and combined Figure 3 As shown, the wire separating assembly 30 in this application includes a fixing plate 301, a cylinder 302, a connecting plate 303, a first side plate 304, a second side plate 305, a third side plate 306, and a fourth side plate 307. The connecting plate 303 is fixed on the first frame 10. The fixing plate 301 is connected to the connecting plate 303 through the first side plate 304. The second side plate 305 and the third side plate 306 are disposed opposite to each other between the fixing plate 301 and the connecting plate 303, and the third side plate 306 can move along the extension and retraction direction of the cylinder 302. The cylinder 302 is fixed on the fixing plate 301. The push rod 3021 on the cylinder 302 is connected to the fourth side plate 307. The fourth side plate 307 is located between the second side plate 305 and the third side plate 306 and is connected to the third side plate 306. A magnetic element is provided on the third side plate 306.

[0047] In use, after the connecting plate 303 is fixed on the corresponding first frame 10, and after all the components are fixed, the first side plate 304, the second side plate 305, the third side plate 306 and the fourth side plate 307 form a cavity for placing the iron wire. When the magnetic component on the third side plate 306 attracts the corresponding iron wire, the cylinder 302 drives the push rod 3021 to move. The push rod 3021 pushes the third side plate 306 to move through the fourth side plate 307, so that the iron wire on the third side plate 306 can move to the preset position.

[0048] Furthermore, to facilitate fixing the magnetic component to the third side plate 306, such as... Figure 3 As described above, this application provides a placement groove 3061 on the third side plate 306, wherein the magnetic component is located in the placement groove 3061.

[0049] In some embodiments, such as Figure 2 As shown, the first frame 10 in this application includes a fixing groove 101 and a guide rod 102, wherein the guide rod 102 is disposed on the bottom surface of the fixing groove 101, and the connecting plate 303 is disposed on the fixing groove 101. The first frame 10 also includes a base plate 103 and an electrical control box 104. The base plate 103 is disposed on the guide rod 102 and is located below the fixing groove 101. The electrical control box 104 is fixed above the fixing groove 101 and is used to store various electrical equipment.

[0050] In some embodiments, such as Figure 5 As shown, the wire feeding assembly 40 in this application includes a guide plate 401, a fixed base 402, a gripper, a first driving member, and a second driving member. The first driving member is connected to the guide plate 401 and is slidably connected to the second frame 20. The first driving member can drive the guide plate 401 to move along a first direction in the second frame 20. The gripper is movably connected to the side of the guide plate 401 away from the first driving member. The fixed base 402 is fixed to the guide plate 401. The second driving member is disposed on the fixed base 402 and cooperates with the gripper to drive the gripper to move along a second direction, wherein the second direction is perpendicular to the first direction.

[0051] The first direction mentioned above is as follows: Figure 1 The X-axis direction is defined as the first direction, and the Y-axis direction as the second direction. In use, after the wire separating assembly 30 moves the wire to a preset position, the first drive component moves the guide plate 401 along the X-axis to the preset position. Then, the second drive component moves the gripper along the second direction to the preset position, at which point the gripper grips the corresponding wire. Once the gripper grips the wire, the first and second drive components are controlled to move the gripper into the mold of the horizontal injection molding machine, placing the gripped wire inside the mold.

[0052] In some embodiments, such as Figure 5 As shown, the first driving component in this application includes a first slider 403, a first motor 404, a lead screw 405, and a lead screw seat 406; as Figure 4 As shown, the second frame 20 includes a T-shaped bracket 201 and a track 202 disposed on the T-shaped bracket 201, the track 202 extending along the X-axis direction.

[0053] The first slider 403 is slidably connected to the track 202 on the second frame 20, and the first slider 403 is connected to the guide plate 401 through the limiting groove (not shown in the figure). The first motor 404 is fixed on the limiting groove. The output shaft of the first motor 404 is connected to the lead screw 405 through the coupling. The lead screw seat 406 is connected to the lead screw 405. The lead screw seat 406 is located in the limiting groove and is connected to the first slider 403.

[0054] In use, by starting the first motor 404, the first motor 404 drives the lead screw 405 to rotate. The lead screw seat 406 moves along the axial direction of the lead screw 405 under the limiting action of the limiting groove. Since the lead screw seat 406 is connected to the first slider 403, when the lead screw seat 406 moves, it can drive the slider 403 to slide relative to the track 202, thereby achieving the purpose of driving the guide plate 401 to move along the X-axis.

[0055] In some embodiments, such as Figure 5 and combined Figure 6 As shown, the second driving component in this application includes a belt 407, a second slider 408, a clamping plate 409, a pulley (not shown in the figure), and a second motor 4014; wherein, a guide rail 40101 is provided on the guide plate 401, the guide rail 40101 extends along the second direction, the second slider 408 is slidably connected to the guide rail 40101, and the second slider 408 is connected to the belt 407 through the clamping plate 409, and the gripper is fixed on the second slider 408; the second motor 4014 is fixed on the fixed base 402, the output shaft of the second motor 4014 is connected to the pulley, and the two ends of the belt 407 are correspondingly sleeved on the two pulleys.

[0056] In use, the second motor 4014 drives the pulley to rotate, which in turn drives the belt 407 to rotate. Since the second slider 408 is connected to the belt 407 via the clamping plate 409, and the second slider 408 is slidably connected to the guide rail 40101, when the belt 407 rotates, it can drive the second slider 408 to move along the Y-axis. Since the gripper is fixed on the second slider 408, when the second slider 408 moves along the Y-axis, it can drive the gripper to move along the Y-axis.

[0057] In some embodiments, such as Figure 5As shown, the gripper in this application includes an air valve 4010 and an air gripper 4011. The air valve 4010 is fixed on the second slider 408, and the air gripper 4011 is connected to the air valve 4010.

[0058] The structure of the pneumatic gripper 4011 in this application is prior art and will not be described in detail here. The air pump is connected to the air valve 4010 through an air pipe. In use, the air valve 4010 is opened, and the air pump provides power to the pneumatic gripper 4011, so that the pneumatic gripper 4011 can grasp the corresponding iron wire.

[0059] In some embodiments, when the pneumatic gripper 4011 in the wire feeding assembly is gripping the wire, in order to facilitate positioning of each wire before gripping, such as... Figure 5 As shown, the wire feeding assembly 40 also includes a connecting seat 4012 and a positioning plate 4013. The connecting seat 4012 is fixed on the guide plate 401, and the positioning plate 4013 is disposed on the connecting seat 4012. The positioning plate 4013 is provided with a guide hole 40131, and the position of the positioning plate 4013 corresponds to the position of the pneumatic gripper 4011.

[0060] When in use, the iron wire passes through the corresponding guide hole 40131 and is located below the pneumatic gripper 4011, which facilitates the gripping of the pneumatic gripper 4011.

[0061] like Figure 7 As shown, the structure of the iron wire taking assembly 50 in this application is the same as that of the iron wire placing assembly 40 except for the two components, the connecting seat 4012 and the positioning plate 4013. The working principle and working process are also the same. Therefore, the structure of the iron wire taking assembly 50 can be referred to the structure of the iron wire placing assembly 40, and will not be repeated here.

[0062] In some embodiments, to facilitate the synchronous movement of the wire feeding assembly 40 and the wire picking assembly 50 along the X-axis direction, such as... Figure 5 As shown, the automatic material handling equipment for the injection molding machine also includes a connecting rod 60, and the iron feeding wire assembly 40 and the iron picking wire assembly 50 are connected along the first direction through the connecting rod 60.

[0063] When in use, when the wire release assembly 40 moves along the X-axis, the wire take-up assembly 50 can be driven to move synchronously along the X-axis through the connecting rod 60.

[0064] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0065] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
