The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0040] like Figures 1 to 9 As shown, an injection molding machine for screw production of the present invention includes an injection molding machine body 1, a manipulator 2, a feeding table 3, a conveyor belt 11 and a vibrating loading tray 4. The manipulator 2 and the feeding table 3 are arranged on one side of the injection molding machine body 1. The feeding table 3 is used to place the screws 01 to be injected. The manipulator 2 is used to clamp the screws 01 on the feeding table 3 and transfer them to the injection molding machine body 1. The screws 01 on the vibrating loading tray 4 enter the conveyor belt 11. The conveyor belt 11 transports the screws 01 to the feeding table 3 to complete material preparation, and then the screws 01 are transferred by the manipulator 2 for injection molding.

A through hole 31 is provided through the feeding table 3, and the through hole 31 is connected to the clamping hole 5. The conveyor belt 11 is provided at the bottom of the feeding table 3, and the upper layer of the conveyor belt 11 is arranged through the through hole 31. A plurality of placement seats 6 for placing screws 01 are provided on the conveyor belt 11, and the plurality of placement seats 6 are arranged along the conveying direction of the conveyor belt 11, and the plurality of clamping holes 5 are arranged at intervals along the conveying direction of the conveyor belt 11. An opening is provided on one side of the placement seat 6 close to the clamping hole 5, that is, the screw 01 can be separated from the placement seat 6 through the opening, and a magnetic body 7 is provided on the inner wall of the clamping hole 5, and the magnetic body 7 is provided as a magnet with magnetism to attract the screw 01 to enter the clamping hole 5. When the conveyor belt 11 conveys the screws 01, it drives multiple placement seats 6 to pass through multiple clamping holes 5 in sequence. When the placement seat 6 moves to a point where its opening corresponds to the clamping hole 5, the magnetic body 7 attracts the screws 01 in the placement seat 6 into the clamping hole 5, and then after all the multiple placement seats 6 have moved through the multiple clamping holes 5, each clamping hole 5 will suck in the screws 01 in sequence, completing the loading and improving the processing efficiency.

[0042] Reference Figure 6 In order to facilitate the manipulator 2 to clamp the screw 01, the clamping hole 5 is provided to include a placement portion 51 and an output portion 52. The output portion 52 and the placement portion 51 are arranged in the vertical direction, and the output portion 52 is arranged on the side of the placement portion 51 close to the manipulator 2, and the magnetic body 7 is arranged in the placement portion 51. A push rod 8 is arranged in the through hole 31. The push rod 8 is arranged at one end of the placement portion 51 away from the output portion 52, and the push rod 8 is slidably arranged in the placement portion 51 in the direction toward the output portion 52. When the screw 01 enters the placement portion 51, it corresponds to the end of the push rod 8, and then the push rod 8 is slid, and the push rod 8 drives the screw 01 to move toward the output portion 52 until the end of the screw 01 moves to the outside of the output portion 52, that is, the end of the screw 01 is on the outside of the feeding table 3, so that the manipulator 2 can clamp the screw 01 and transfer it.

[0043] Reference Figures 3 to 7In order to facilitate the adjustment of the position of the push rod 8, a control member 81 is provided in the through hole 31. The control member 81 includes a control plate 811 and a push member 812. The control plate 811 is slidably provided in the through hole 31, and the sliding direction of the control plate 811 is the same as the sliding direction of the push rod 8. The push member 812 can be provided as a cylinder. The push member 812 is provided on one side of the feeding table 3. The side of the control plate 811 extends to the outside of the through hole 31. The output end of the push member 812 is connected to the control plate 811, and the end of the push rod 8 away from the lead-out portion 52 is connected to the control plate 811. The push member 812 drives the control plate 811 to move, and the movement of the control plate 811 drives the push rod 8 to move, thereby adjusting the position of the screw 01. In addition, there are multiple push rods 8 and multiple clamping holes 5 correspondingly arranged, and the multiple push rods 8 are all connected to the control board 811. That is, when the control board 811 moves, the positions of the multiple push rods 8 are adjusted at the same time, and then the positions of the multiple screws 01 are adjusted at the same time, so that their ends are outside the feeding table 3 for clamping by the robot 2.

[0044] Reference Figure 6 A clamping plate 82 is provided on the push rod 8. The clamping plate 82 and the magnetic body 7 are both arranged in an arc shape, and the inner radius of the clamping plate 82 and the magnetic body 7 is the same as the radius of the screw 01. The inner wall of the magnetic body 7 abuts against the side of the screw 01. After the screw 01 enters the clamping hole 5, the screw 01 and the clamping plate 82 are arranged at intervals, and then the push rod 8 is moved. After the push rod 8 and the end of the screw 01 abut, the inner wall of the clamping plate 82 moves to cooperate with the screw 01, and the clamping plate 82 and the magnetic body 7 clamp the screw 01 to reduce the deviation of the screw 01 during movement. At the same time, after the end of the screw 01 moves to the outside of the outlet 52, the screw 01 can be in a stable state, which improves the feeding accuracy for the robot 2 to clamp.

[0045] Reference Figure 2 and Figure 8 In order to facilitate the screw 01 to enter the placement seat 6, the vibration loading tray 4 includes a discharge guide rail 9. The screw 01 is placed in the vibration loading tray 4 and loaded through the discharge guide rail 9. The end of the discharge guide rail 9 away from the vibration loading tray 4 is arranged close to the conveyor belt 11, that is, the discharge end of the discharge guide rail 9 is arranged close to the conveyor belt 11. The discharge guide rail 9 is arranged at the end of the placement seat 6 close to the guide rail. The discharge end of the discharge guide rail 9 is provided with a bending portion 91 toward the placement seat 6. The discharge guide rail 9 and the placement seat 6 are arranged on the same horizontal plane. Under the action of the vibration loading tray 4, the screw 01 will gradually move toward its discharge end in the discharge guide rail 9. When the placement seat 6 moves to the bending portion 91, and the bending portion 91 corresponds to the opening of the placement seat 6, the screw 01 enters the placement seat 6 through the opening, and then the conveyor belt 11 drives the placement seat 6 to move, and the screw 01 is placed in multiple placement seats 6 in turn, and the material preparation is completed, so that the screw 01 can be placed in the feeding table 3 later.

[0046] Reference Figure 4 and Figure 5 In order to reduce the phenomenon that the screw 01 is separated from the placement seat 6 during the conveying process, the inner wall of the through hole 31 is provided with a shielding portion 311, which is arranged along the conveying direction of the conveyor belt 11, and a plurality of clamping holes 5 are arranged along the length direction of the shielding portion 311. An opening connected to the clamping hole 5 is provided on the shielding portion 311, and one side of the placement seat 6 where the opening is provided is in sliding contact with the shielding portion 311. That is, when the placement seat 6 moves in the through hole 31, the shielding portion 311 blocks the screw 01, reducing the phenomenon that the screw 01 is separated from the placement seat 6. At the same time, when the placement seat 6 passes through the clamping hole 5 and the openings of the two are opposite, the screw 01 can enter the clamping hole 5 through the opening.

[0047] Reference Figure 4 and Figure 8 A baffle 32 is provided on the feeding table 3, and the baffle 32 is provided between the feeding table 3 and the bending portion 91, and the baffle 32 and the shielding portion 311 are provided on the same straight line, that is, the baffle 32 is also provided along the conveying direction of the conveyor belt 11. After the screw 01 passes through the bending portion 91 and enters the placement seat 6, the placement seat 6 moves to the baffle 32, and the opening of the placement seat 6 is shielded by the baffle 32, thereby reducing the phenomenon that the screw 01 is separated from the placement seat 6 before entering the through hole 31, thereby improving the stability of the screw 01 conveying.

[0048] Reference Figure 4 and Figure 8 There are two groups of clamping holes 5 and placement seats 6, and the two groups of placement seats 6 are arranged at intervals along the conveying direction perpendicular to the conveyor belt 11. The two groups of clamping holes 5 are arranged between the two groups of placement seats 6, and the openings on the two groups of placement seats 6 are arranged facing each other. There are also two corresponding discharge guide rails 9, and the two discharge guides are arranged between the two groups of placement seats 6. The two bending parts 91 are bent toward the direction of the two groups of placement seats 6. By setting two groups of placement seats 6 and clamping holes 5, the preparation quantity of screws 01 is increased, and the injection molding efficiency is improved at the same time.

[0049] Reference Figure 8 and Fig. 9A baffle 92 is slidably provided on the inner wall of the bending portion 91, and the baffle 92 slides into the bending portion 91 to block the screw 01. At this time, the screw 01 stops feeding. After the baffle 92 slides to the outside of the bending portion 91, the screw 01 can enter the placement seat 6. A rotating rod 93 is rotatably provided on the bending portion 91, and a gear 931 is coaxially provided on the rotating rod 93. A tooth groove 921 is provided on the baffle 92 along its sliding direction. The gear 931 and the tooth groove 921 are meshed. The bottom end of the rotating rod 93 extends to the outside of the bending portion 91, and a gear 2 932 is provided at the bottom end of the rotating rod 93. 1 is slidably provided with a top block 94 at the bottom, and the top block 94 is slidably provided in the direction toward the placement seat 6. A tooth groove 941 is provided on the side of the top block 94, and the tooth groove 941 is provided along the sliding direction of the top block 94, and the tooth groove 941 is meshed with the gear 932. An inclined surface 942 is provided at one end of the top block 94 close to the placement seat 6, and the inclined surface 942 is provided outside the bending portion 91. An elastic member 95 is provided on the bending portion 91. The elastic member 95 can be set as a spring, one end of the spring is connected to the bending portion 91, and the other end is connected to the top block 94. The spring is used to drive the top block 94 to move in the direction toward the placement seat 6.

[0050] In the initial state, the inclined surface 942 moves to the outside of the bending portion 91, the baffle 92 is inside the bending portion 91, and the screw 01 stops moving. When the placement seat 6 moves to the bending portion 91, the placement seat 6 abuts against the inclined surface 942. The placement seat 6 presses the top block 94 to move by abutting against different positions on the inclined surface 942. The movement of the top block 94 drives the rotating rod 93 to rotate. The rotation of the rotating rod 93 drives the baffle 92 to move to the outside of the bending portion 91 through the gear 1 931, thereby releasing the restriction on the screw 01 so that the screw 01 can pass through the opening and enter the placement seat 6. At the same time, after the placement seat 6 moves to separate from the bending portion 91, the baffle 92 moves to the initial position, and restricts the screw 01 again, thereby reducing the phenomenon of the screw 01 falling off after the placement seat 6 and the bending portion 91 are separated.

[0051] The implementation principle of the present invention is as follows: the screws 01 are gradually arranged and enter the discharge guide rail 9 under the action of the vibrating loading tray 4 and gradually move to the bending portion 91, the conveyor belt 11 drives the placement seat 6 to move to the bending portion 91, and at the same time, the placement seat 6 presses the top block 94 to drive the baffle 92 to move to the outside of the bending portion 91, and the screws 01 pass through the opening of the placement seat 6 and enter the placement seat 6, and then the conveyor belt 11 continues to convey, and multiple placement seats 6 move through the bending portion 91, so that each placement seat 6 has a screw 01, and the placement seat 6 continues to move to block its opening through the blocking rod 32 and the shielding portion 311, so that the screws 01 move with the placement seat 6, and when the placement seat 6 is placed, the screws 01 are moved. The seat 6 moves through multiple openings in sequence, and under the action of the magnetic body 7, the screws 01 enter the corresponding placement parts 51 in sequence, and then the pushing member 812 drives the control board 811 to move, and the control board 811 drives the push rod 8 to move, and the push rod 8 moves to push the screw 01 to move, until the ends of the screws 01 in the multiple clamping holes 5 are all moved to the outside of the feeding table 3 for the robot 2 to clamp and transfer. The present invention arranges a conveyor belt 11 and a placement frame. After the conveyor belt 11 drives the placement frame to pass through multiple clamping holes 5, the screws 01 can be placed in the designated clamping holes 5 respectively, thereby improving the efficiency of placing the screws 01 on the feeding table 3, thereby improving the injection molding efficiency.

[0052] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
