Description

Technical Field

[0001] The present invention relates to a feeder used for injection molding, in particular to a visual universal shaft core feeder for injection molding. Background Art

[0002] As is known to all, a fan comprises components such as blades with a shaft core and a fan shell with a shaft sleeve. The blades are assembled on the fan shell by means of the insertion fit between the shaft core and the shaft sleeve.

[0003] Among them, the production process of fan blades cannot be separated from the use of injection molds. First, the shaft core is buried in the injection mold, and then the molten material is injected into the injection mold to obtain a fan blade with a shaft core.

[0004] Currently, operators manually place the shaft core at the loading position, and then the injection molding machine's robot grabs the shaft core from the loading position and embeds it into the injection mold. This has the disadvantages of low efficiency and heavy operator burden, making it unsuitable for automated operations.

[0005] Therefore, there is an urgent need for a visual universal shaft core feeder for injection molding to overcome the above-mentioned defects. Summary of the Invention

[0006] The purpose of the present invention is to provide a visual universal shaft core feeder for injection molding, so as to correctly feed the randomly arranged shaft sleeves to the feeding pipe head, thereby ensuring that the shaft core is subsequently embedded in the injection mold in the correct position and orientation.

[0007] To achieve the above-mentioned objectives, the present invention provides a visual universal core feeder for injection molding, comprising a frame, a receiving seat, a vibrating screening disc, a material distribution mold base, a top blowing seat, a top blowing driver, a feeding pipe head, a visual device, a manipulator, and a controller electrically connected to the vibrating screening disc, the top blowing driver, the visual device, and the manipulator, respectively. The receiving seat is movably mounted on the frame and has at least one receiving position and one discharging position relative to the frame. The receiving seat is provided with an adsorption channel and a receiving groove with an upwardly facing notch extending through a first side surface of the receiving seat. The adsorption channel communicates with the receiving groove at the end surface of the receiving groove away from the first side surface of the receiving seat. The vibrating screening disc is mounted on the frame. The vibrating screening disc is externally connected to an external delivery pipe for orderly transporting the cores vibrated and screened by the vibrating screening disc to the receiving groove. When the receiving seat switches to the receiving position or the discharging position, the receiving groove is aligned or offset with the external delivery pipe accordingly. The feed die base is mounted on the frame. The feed die base is provided with a plurality of sorting grooves spaced apart from each other and with notches facing upward. The sorting grooves also extend through the first and second opposing sides of the feed die base. The top blowing seat is provided with a number of top blowing rods equal to the number of the sorting grooves, which are used to deliver the cores in the sorting grooves out of the feed die base. Each top blowing rod extends into the sorting groove from the second side of the feed die base, and a blowing channel extending through the center of each top blowing rod is provided. The top blowing driver is mounted on the frame and is used to drive the top blowing seat to move toward or away from the first side of the feed die base. The feed pipe head is connected to the sorting grooves on the first side of the feed die base via an air pipe. The visual device is mounted on the frame and is located next to the receiving seat. The manipulator is mounted on the frame and, in cooperation with the visual device, transfers the cores in the receiving grooves to the sorting grooves.

[0008] Compared with the prior art, with the design that "the receiving seat is provided with an adsorption channel and a receiving groove with an upward notch and penetrating the first side surface of the receiving seat, the adsorption channel is connected with the receiving groove at the end surface of the receiving groove away from the first side surface of the receiving seat", therefore, when switching to the receiving position, the receiving seat aligns the receiving groove with the external delivery pipe, so that the shaft core vibrated and screened by the vibrating screening disc enters the receiving groove in an orderly manner along the external delivery pipe, and the shaft core entering the receiving groove is adsorbed by the adsorption channel to a position abutting against the end surface of the receiving groove, which plays a role of precise positioning on the one hand, and can prevent the shaft core in the receiving groove from running around when the receiving seat switches from the receiving position to the discharging position on the other hand, so as to prepare for the transfer of the shaft core by the robot; when the receiving seat switches to the discharging position, the robot picks up the shaft core in the receiving groove, The visual device visually captures the shaft core picked up by the robot and feeds back the visual capture signal to the controller; the controller processes the capture signal to obtain a processing signal to determine whether the orientation of the shaft core picked up by the robot is correct and whether there are defective shaft cores. The controller controls the robot to make corresponding movements based on the processed signal, so that the shaft core with the wrong orientation is adjusted to the correct orientation before being placed in the sorting groove of the dividing mold base, and the defective shaft core is transferred to the corresponding collection position by the robot; the shaft core in the sorting groove is pushed out of the dividing mold base by the top blowing rod of the top blowing seat under the drive of the top blowing driver on the top blowing seat, and is sent to the feeding pipe head along the air pipe under the blowing action of the top blowing rod; thus, the randomly arranged shaft cores are correctly loaded to the feeding pipe head, thereby ensuring that the shaft core is subsequently buried in the injection mold in the correct position and orientation.

[0030] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0031] See also Figures 1 to 4 and Figure 12 The visual universal shaft core feeder 100 for injection molding of the present invention includes a frame 10, a material receiving seat 20, a vibration screening plate 30, a material dividing mold seat 40, a top blowing seat 50, a top blowing driver 60, a feeding pipe head 70, a visual device 80a, a manipulator 80b and a controller 80c electrically connected to the vibration screening plate 30, the top blowing driver 60, the visual device 80a and the manipulator 80b respectively. Optionally, as an example, the controller 80c is a PLC controller. Obviously, according to actual needs, the controller 80c can also be other types of controllers, so it is not limited to this.

[0032] The receiving seat 20 is movably mounted on the frame 10 so that the receiving seat 20 can have at least Figure 2 The splice position shown and Figure 4 The material receiving seat 20 is provided with an adsorption channel 21 and a notch 231 that faces upward and passes through the first side surface 22 of the material receiving seat 20 (see FIG. Figure 7 ) of the receiving groove 23, the adsorption channel 21 is connected to the receiving groove 23 on the end surface 232 of the first side surface 22 of the receiving seat 20, and the state is shown in FIG. Figure 2 、 Figure 4 and Figure 7As shown; optionally, combined Figures 1 to 4 The receiving seat 20 is slidably mounted on the frame 10 along the X-axis direction so that the receiving seat 20 can slide on the frame 10. Figure 2 The splice position shown is the same as Figure 4 The material receiving seat 20 can be switched between the material receiving positions shown in the figure, so the amount of space occupied by the frame 10 during the movement can be reduced; obviously, according to actual needs, the material receiving seat 20 can also be rotated in the material receiving seat 20. Figure 2 The splice position shown is the same as Figure 4 The discharging positions shown are switched between Figures 1 to 4 Limits shown.

[0033] The vibration screening plate 30 is mounted on the frame 10, and the frame 10 provides support for the vibration screening plate 30; the vibration screening plate 30 is externally connected to the shaft core 200 (see FIG. Figure 5 and Figure 6 ) one by one in an orderly manner to the outer delivery pipe 31 of the receiving groove 23, the outer delivery pipe 31 switches to the receiving seat 20 Figure 2 The material receiving position shown is aligned with the material receiving groove 23 to meet the need for the shaft core 200 to enter the material receiving groove 23 along the external delivery pipe 31; the external delivery pipe 31 is switched to the material receiving seat 20 as shown. Figure 4 The material discharging position shown is misaligned with the material receiving groove 23 to prevent the shaft core 200 from entering the material receiving groove 23 along the external delivery pipe 31.

[0034] The dividing die base 40 is assembled on the frame 10, and the frame 10 provides support for the dividing die base 40; the dividing die base 40 is provided with a plurality of sorting grooves 41 spaced apart from each other and with the notches 411 facing upwards; Figures 8 to 10 As an example, the number of the sorting grooves 41 is four. Obviously, according to actual needs, the number of the sorting grooves 41 can also be three or five. Figures 8 to 10 In addition, combined with Figure 9 and Figure 10 The sorting groove 41 also passes through the first side surface 42 and the second side surface 43 opposite to the material dividing die base 40.

[0035] The top blowing seat 50 is provided with the same number of top blowing rods 51 as the sorting grooves 41 and used to send the shaft core 200 in the sorting grooves 41 out of the material distribution mold seat 40. Each top blowing rod 51 extends into the sorting groove 41 from the second side surface 43 of the material distribution mold seat 40. Figure 10 Each top blowing rod 51 is provided with a blowing channel 511 arranged through the center, the state shown Figure 9As shown; therefore, in the process of ejecting the shaft core 200 in the sorting groove 41, the external gas can also apply air pressure to the shaft core 200 through the blowing channel 511, so that the shaft core 200 is sent to the feeding pipe head 70 along the air pipe 71 described below under the action of air pressure, thereby satisfying the need of the robot in the injection molding machine to take away the shaft core 200 at the feeding pipe head 70.

[0036] The top blowing driver 60 is mounted on the frame 10, and the frame 10 provides support for the top blowing driver 60; the top blowing driver 60 is used to drive the top blowing seat 50 to move closer to or away from the first side surface 42 of the material dividing mold base 40, so as to meet the need for the top blowing seat 50 to automatically slide back and forth under the action of the top blowing driver 60; optionally, Figures 8 to 10 In the example, the top blowing driver 60 is a cylinder. Obviously, according to actual needs, the top blowing driver 60 can also be a hydraulic cylinder, etc. Figures 8 to 10 Limits shown.

[0037] The feeding pipe head 70 is connected to the sorting groove 41 at the first side 42 of the material distribution mold base 40 through the air pipe 71. Figure 1 and Figure 3 As an example, an L-shaped bracket 11 is provided on the frame 10, which protrudes outward from the frame 10 in the Y-axis direction, and a transverse bracket 12 is provided at a position of the L-shaped bracket 11 away from the frame 10, which protrudes outward from the L-shaped bracket 11 in the X-axis direction; the feeding pipe head 70 is assembled on the transverse bracket 12 at a position away from the L-shaped bracket 11; this design leaves more sufficient space for the robot in the injection molding machine to grab the shaft core 200 at the feeding pipe head 70, thereby improving the reliability of the robot in the injection molding machine to transfer the shaft core 200 at the feeding pipe head 70; it should be noted that since the feeding pipe head 70 is connected to the sorting groove 41 through the air pipe 71, the number of both the feeding pipe heads 70 and the air pipe 71 is the same as the number of the sorting grooves 41, so as to meet the need that each feeding pipe head 70 is connected to a corresponding sorting groove 41 through an air pipe 71.

[0038] The visual device 80a is assembled on the frame 10 and is located next to the material receiving seat 20, and the robot 80b is assembled on the frame 10. With the cooperation of the visual device 80a, the robot 80b transfers the shaft core 200 in the material receiving groove 23 to the sorting groove 41; specifically, the visual device 80a visually captures the shaft core 200 picked up by the robot 80b from the material receiving groove 23, and feeds the captured signal back to the controller 80c, and the controller 80c processes the captured signal to obtain a processing signal indicating whether the orientation of the shaft core 200 picked up by the robot 80b is correct and whether there are defective shaft cores 200. The controller 80c controls the robot 80b according to the processing signal to adjust the shaft core 200 with the wrong orientation to the correct orientation and then place it into the sorting groove 41 of the material dividing mold seat 40, and place the defective shaft core 200 in the storage container 90b described below. It should be noted that, for the shaft core 200 that has entered the receiving groove 23 and is facing the correct direction, the robot 80b directly picks up the shaft core 200 and places it directly into the sorting groove 41, eliminating the need for adjusting the direction. More specifically, as follows:

[0039] like Figures 1 to 7 As shown in FIG. 1 , as an example, the visual universal core feeder 100 for injection molding of the present invention further includes a receiving drive 90a located between the visual device 80a and the receiving seat 20 in the X-axis direction and a storage container 90b assembled at the receiving seat 20. The output end 91 of the receiving drive 90a is assembled and connected to the receiving seat 20 to meet the requirements of the receiving seat 20 driven by the receiving drive 90a. Figure 2 The splice position shown is the same as Figure 4 The storage container 90b is located between the receiving seat 20 and the material distribution die base 40 in the X-axis direction. This design makes the storage container 90b arranged between the receiving seat 20 and the material distribution die base 40 more compact. The opening 92 of the storage container 90b is arranged upward to facilitate the operation of the robot 90b to store the defective shaft core 200 in the storage container 90b. Specifically, Figure 1 、 Figure 3 、 Figure 5 、 Figure 6 and Figure 7 In the embodiment, the material receiving driver 90a is a cylinder. Obviously, the material receiving driver 90a can also be a hydraulic cylinder according to actual needs. Figure 1 、 Figure 3 、 Figure 5 、 Figure 6 and Figure 7 It should be noted that although the drawings show that the visual universal shaft core feeder 100 for injection molding of the present invention also includes a storage container 90b, it is obvious that the storage container 90b can also be deleted according to actual needs, so the drawings are not limited thereto.

[0040] like Figures 1 to 6 As shown in FIG. 1 , as an example, the visual device 80a, the receiving seat 20 and the material dividing die seat 40 are sequentially arranged in the X-axis direction to form a module unit, so that the visual device 80a, the receiving seat 20 and the material dividing die seat 40 are arranged more compactly in the X-axis direction. In addition, the visual device 80a is also arranged horizontally to visually capture the shaft core 200 picked up by the robot 80b from the horizontal direction. Optionally, Figures 1 to 6 As an example, the visual device 80a is a CCD camera. Obviously, the visual device 80a can also be other visual devices depending on actual needs, and is not limited to this. Accordingly, the robot 80b is located on one side of the module unit in the Y-axis direction, and the vibrating screening tray 30 is located on the opposite side of the module unit in the Y-axis direction. This makes the arrangement of the vibrating screening tray 30, the module unit, and the robot 80b in the Y-axis direction more reasonable and compact. The top blowing rod 51 extends into the sorting groove 41 in the Y-axis direction.

[0041] like Figure 2 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7 As shown, as an example, the outlet 211 of the adsorption channel 21 is arranged upward to facilitate the communication operation between the external vacuum device (such as but not limited to a vacuum pump) and the outlet 211 of the adsorption channel 21; the inlet 212 of the adsorption channel 21 is located on the end surface 232 of the material receiving groove 23 away from the first side surface 22 of the material receiving seat 20, so as to better ensure that the adsorption channel 21 performs the adsorption operation on the shaft core 200 at the end surface 232. Figure 7 As an example, the projection of the receiving groove 23 in its length direction is in a "V" shape, so that the receiving groove 23 is arranged to be larger at the top and larger at the bottom, thereby facilitating the robot 80a to take up the shaft core 200 in the receiving groove 23. Figure 2 、 Figure 4 、 Figure 8 and Figure 9 As an example, the first side surface 42 of the dividing die base 40 is equipped with air pipe connectors 44 having the same number as the sorting grooves 41 and connected to the air supply pipes 71 , so that the air pipes 71 can communicate with the sorting grooves 41 through the air pipe connectors 44 .

[0042] like Figure 1 and Figure 3 As shown, as an example, the manipulator 80b is located between the module unit and the L-shaped bracket 11 in the Y-axis direction, so that the arrangement of the manipulator 80b, the module unit and the L-shaped bracket 11 is more reasonable and compact. Figure 1 、 Figure 3 and Figure 11In the figure, as an example, the manipulator 80b includes an X-axis transfer module 81, a Z-axis transfer module 82 mounted on the X-axis transfer module 81, a rotary driver 83 mounted on the Z-axis transfer module 82, and a suction head 84 mounted on the rotary driver 83 and arranged vertically. The suction head 84 is located below the rotary driver 83, and the rotary driver 83 is located below the Z-axis transfer module 82, and the Z-axis transfer module 82 protrudes downward from the X-axis transfer module 81. This design makes the suction head 84 at the bottom of the entire manipulator 80b, thereby facilitating the suction head 84 to take out the shaft core 200 in the receiving groove 23 and put it into the sorting groove 41. Moreover, since the suction head 84 only moves in the X-axis and Z-axis directions during the transfer of the shaft core 200, the path is shorter and the control is simpler. More specifically, in Figure 11 As an example, the rotary actuator 83 is a rotary cylinder. Obviously, it can also be a rotary hydraulic cylinder depending on actual needs. In addition, the suction head 84 is a vacuum suction head. Obviously, it can also be a magnetic suction head, so this is not limited to this. In the robot 80b, since it includes the X-axis transfer module 81, the Z-axis transfer module 82, the rotary actuator 83, and the suction head 84 mounted on the rotary actuator 83 and arranged vertically, the rotary actuator 83 drives the suction head 84 to rotate, for example, between 0 degrees and 180 degrees, to achieve the purpose of adjusting the direction of the shaft core 200.

[0043] Compared with the prior art, the material receiving seat 20 is provided with an adsorption channel 21 and a material receiving groove 23 with a notch 231 facing upward and penetrating the first side surface 22 of the material receiving seat 20, and the adsorption channel 21 is connected to the material receiving groove 23 at the end surface 232 of the material receiving groove 23 away from the first side surface 22 of the material receiving seat 20. Therefore, when switching to Figure 2 When the material receiving position is shown, the material receiving seat 20 aligns the material receiving groove 23 with the external delivery pipe 31, so that the shaft core 200 vibrated and screened by the vibrating screening plate 30 enters the material receiving groove 23 in an orderly manner along the external delivery pipe 31, and the shaft core 200 entering the material receiving groove 23 is adsorbed by the adsorption channel 21 to a position abutting against the end surface 232 of the material receiving groove 23, which plays a role in precise positioning on the one hand, and prevents the shaft core 200 in the material receiving groove 23 from being moved by the material receiving seat 20. Figure 2 The splice position shown switches to Figure 4 The material discharging position shown in the figure is in a state of chaos, in preparation for the transfer of the shaft core 200 by the manipulator 80b; when the receiving seat 20 is switched to the position shown in the figure Figure 4When the material is in the discharge position shown, the manipulator 80b picks up the shaft core 200 in the receiving groove 23, and the visual device 80a performs visual acquisition on the shaft core 200 picked up by the manipulator 80b, and feeds back the visual acquisition signal to the controller 80c; the controller 80c processes the acquisition signal to obtain a processing signal to determine whether the orientation of the shaft core 200 picked up by the manipulator 80b is correct and whether there are defective shaft cores 200. The controller 80c controls the manipulator 80b to make corresponding movements according to the processing signal, so as to adjust the shaft core 200 with the wrong orientation to the correct orientation before placing it into the material distribution mold. The defective shaft cores 200 are placed in the sorting groove 41 of the seat 40, and the defective shaft cores 200 are transferred by the robot 80b to the corresponding collection position, such as but not limited to the storage container 90b; and the shaft cores 200 in the sorting groove 41 are pushed out of the dividing mold seat 40 by the top blowing rod 51 of the top blowing seat 50 under the driving of the top blowing driver 60 on the top blowing seat 50, and are sent to the feeding pipe head 70 along the air pipe 71 under the blowing action of the top blowing rod 51; thereby, the randomly arranged shaft cores 200 are correctly loaded to the feeding pipe head 70, thereby ensuring that the shaft cores 200 are subsequently buried in the injection mold in the correct position and orientation.

[0044] The above disclosure is merely a preferred embodiment of the present invention, which is intended to facilitate understanding and implementation by those skilled in the art. It certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention still fall within the scope covered by the present invention.
