Description

Technical Field

[0001] This application relates to the field of injection molding equipment technology, and in particular to a loading and unloading device for an injection molding machine with an on-board connector. Background Technology

[0002] Automotive connectors are common components in automotive circuits. They are cables with connectors at both ends, and their function is to connect different wires, allowing current to flow and enabling the circuit to perform its intended function. In actual production, injection molding is performed on the connectors and cables to provide good waterproofing at the connection point using rubber.

[0003] Currently, injection molding machines are commonly used for injection molding of vehicle connectors. An injection molding machine includes a lower mold, an upper mold, and an injection head. The upper mold and the lower mold have injection cavities facing each other. An injection molding machine is a mechanical device used to produce plastic products. Its main working principle is to heat the plastic to melt it, and then inject the molten plastic into a pre-made mold with the help of a pressure system. The plastic then cools and solidifies in the mold, ultimately obtaining plastic products of various shapes.

[0004] Currently, when injection molding automotive connectors, operators need to manually align and place the connector onto the lower mold. After injection molding and plastic solidification, the connector is then manually removed. This manual handling of connector removal and placement on the lower mold poses a significant safety risk. Summary of the Invention

[0005] To reduce safety risks during the production of vehicle connectors, this application provides a loading and unloading device for an injection molding machine for vehicle connectors.

[0006] The technical solution provided in this application for a vehicle-mounted connector injection molding machine loading and unloading device is as follows: A vehicle-mounted connector injection molding machine loading and unloading device includes a conveyor belt, a conveying device, and a pick-and-place device. The conveyor belt is disposed on one side of the injection molding machine, and the conveying direction of the conveyor belt extends toward the lower mold of the injection molding machine. Multiple conveying devices are disposed on the conveyor belt and are used to accommodate connectors. The pick-and-place device is disposed on the injection molding machine and located between the lower mold and the conveyor belt. The pick-and-place device is used to move the connectors on the conveying devices to the lower mold and to move the connectors that have been injection molded on the lower mold to the conveying devices.

[0007] Optionally, the conveying device includes a connecting rod, a receiving frame, and a fixing member. Multiple connecting rods are arranged on the conveyor belt in a direction perpendicular to the surface of the conveyor belt. The receiving frame is located at the end of the connecting rod away from the conveyor belt. The fixing member is located on the receiving frame and is used to fix the connector placed in the receiving frame.

[0008] Optionally, the receiving frame is a hollow frame with one side open, and the side of the receiving frame away from the conveyor belt also has a groove for the cable to pass through.

[0009] Optionally, the fixing member includes a first suction cup, and multiple first suction cups are provided on the inner wall of the receiving frame.

[0010] Optionally, the pick-and-place device includes a turntable, pick-and-place rods, pick-and-place components, a driving component, and a rotating component. The turntable is rotatably mounted on the injection molding machine. Two pick-and-place rods are rotatably mounted on the turntable. The pick-and-place components are provided at the ends of the two pick-and-place rods and are used to fix connecting heads. The driving component is mounted on the turntable and is used to drive the two pick-and-place rods to rotate closer to or further away from each other. The rotating component is mounted on the injection molding machine and is used to drive the turntable to rotate.

[0011] Optionally, the pick-and-place component includes a second suction cup and an air pump. Multiple second suction cups are provided at the end of the pick-and-place rod, and the air pump is provided on the pick-and-place rod and connected to the multiple second suction cups.

[0012] Optionally, the driving component includes a drive motor, a bidirectional lead screw, and a slider. The pick-and-place rod has a sliding hole along its length on the side near the injection molding machine. The cross-sectional shape of the sliding hole is cross-shaped. The slider is slidably disposed in the sliding hole, and cylindrical rods adapted to the sliding hole are provided on both sides of the slider. The bidirectional lead screw is rotatably disposed on the turntable through a fixed rod, and two sliders are threaded through both ends of the bidirectional lead screw. The drive motor is disposed on the injection molding machine and connected to the bidirectional lead screw.

[0013] Optionally, the rotating component includes a rotating motor, which is embedded in the injection molding machine, and the output axis of the rotating motor extends upward and is connected to the turntable.

[0014] Optionally, a material collection frame is provided below the conveyor belt and on the side of the conveyor belt away from the injection molding machine.

[0015] In summary, this application includes at least one of the following beneficial technical effects: 1. Multiple conveyor devices are moved by a conveyor belt. When the conveyor device holding the connector to be processed moves to the opposite side of the injection molding machine, the pick-and-place device removes the connector from the conveyor device and conveys it to the lower mold. At the same time, the pick-and-place device also removes the connector that has already been injection molded from the lower mold and conveys it to the conveyor device. When the conveyor device holding the processed connector moves to the side away from the injection molding machine, the conveyor device removes the connector and drops it into the collection box. Meanwhile, the operator places the connector to be processed into the empty conveyor device. This eliminates the need for operators to manually load and unload materials on the lower mold, reducing safety risks during the production process. 2. At the same time, operators only need to place the connector to be processed into the receiving frame, without having to pick up or put away the processed connector, thus reducing the labor intensity of workers.

Detailed Implementation

[0020] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0021] This application discloses a loading and unloading device for a vehicle-mounted connector injection molding machine, referring to... Figure 1 A loading and unloading device for an injection molding machine of automotive connectors includes a conveyor belt 1, a conveying device 2, and a pick-and-place device 3. The conveyor belt 1 is a conventional waist-shaped conveyor belt 1, which is installed in the production workshop via a mounting frame and located on one side of the injection molding machine. The conveyor belt 1 is installed horizontally, and its center point is flush with the upper surface of the lower mold plate. The conveying direction of the conveyor belt 1 extends towards the lower mold of the injection molding machine. Multiple conveying devices 2 are evenly spaced on the conveyor belt 1, and the conveying devices 2 are used to accommodate connectors. The pick-and-place device 3 is located on the injection molding machine and between the lower mold and the conveyor belt 1. The pick-and-place device 3 is used to move connectors on the conveying devices 2 closer to the injection molding machine to the lower mold, and to move connectors that have been injection molded on the lower mold to the conveying devices 2 closer to the injection molding machine. A collection frame 9 is provided below the conveyor belt 1 and on the side of the conveyor belt 1 away from the injection molding machine. The collection frame 9 is used to collect connectors that have been injection molded.

[0022] Multiple conveyor devices 2 are moved by the conveyor belt 1. When the conveyor device 2 with the connector to be processed moves to the opposite side of the injection molding machine, the pick-and-place device 3 removes the connector from the conveyor device 2 and conveys it to the lower mold. At the same time, the pick-and-place device 3 also removes the connector that has been injection molded from the lower mold and conveys it to the conveyor device 2. When the conveyor device 2 with the processed connector moves to the side away from the injection molding machine, the conveyor device 2 removes the connector and drops it into the collection frame 9. At the same time, the operator places the connector to be processed in the empty conveyor device 2. Thus, the operator does not need to manually load and unload the material on the lower mold, reducing the safety risks in the production process.

[0023] Reference Figure 1 and Figure 2 The conveying device 2 includes connecting rods 21, a receiving frame 22, and a fixing member 4. Multiple connecting rods 21 are evenly spaced on the conveyor belt 1, perpendicular to its surface. The receiving frame 22 is located at the end of the connecting rods 21 furthest from the conveyor belt 1. The fixing member 4 is mounted on the receiving frame 22. When the connector is placed in the receiving frame 22, the fixing member 4 secures the connector. When the connector needs to be moved to the lower mold or when the processed connector needs to be fed into the collection frame 9, the fixing member 4 releases the connector from its fixation.

[0024] Reference Figure 2 The receiving frame 22 is a hollow frame with one side open. The size of the receiving frame 22 is adapted to the size of the connector. A groove 23 for cable passage is also provided on the side of the receiving frame 22 away from the conveyor belt 1. When the connector is placed in the receiving frame 22, the cable on the connector extends to the outside of the receiving frame 22 through the groove 23. The first fixing member 4 includes a first suction cup 41, and multiple first suction cups 41 are provided on the inner wall of the receiving frame 22.

[0025] The connector to be processed is placed into the receiving frame 22 on the side away from the injection molding machine. The first suction cup 41 is activated, and the first suction cup 41 fixes the connector in the receiving frame 22. When the receiving frame 22 moves closer to the injection molding machine, the receiving frame 22 is in an open-up state, which makes it easy for the pick-and-place device 3 to take out the connector in the receiving frame 22. At the same time, it is also easy for the pick-and-place device 3 to place the processed connector in the receiving frame 22. The receiving frame 22 continues to move under the drive of the conveyor belt 1. When the receiving frame 22 containing the processed connector moves away from the injection molding machine, the receiving frame 22 is in an open-down state, which makes it easy for the processed connector to fall into the collection frame 9 for storage.

[0026] Reference Figure 1 and Figure 3The pick-and-place device 3 includes a turntable 51, pick-and-place rods 52, pick-and-place components 6, a drive component 7, and a rotating component 8. The turntable 51 is rotatably mounted on the injection molding machine. To ensure that the surface of the turntable 51 and the surface of the lower mold are on the same horizontal line, a pad can be placed below the turntable 51. The pick-and-place rods 52 are rectangular rods, and two pick-and-place rods 52 are rotatably mounted on the turntable 51. Pick-and-place components 6 are provided at the ends of both pick-and-place rods 52 and are used to fix the connecting heads. The drive component 7 is mounted on the turntable 51 and is used to drive the two pick-and-place rods 52 to rotate closer to or further apart from each other. The rotating component 8 is mounted on the injection molding machine, connected to the turntable 51, and is used to drive the turntable 51 to rotate.

[0027] Reference Figure 3 The driving component 7 includes a drive motor 71, a bidirectional lead screw 72, and a slider 73. A sliding hole 521 is provided along the length of the pick-and-place rod 52 on the side near the injection molding machine. The sliding hole 521 has a cross-shaped cross section and passes through the opposite sides of the two pick-and-place rods 52. The slider 73 is slidably disposed within the sliding hole 521, and cylindrical rods 74 adapted to the spaces on both sides of the sliding hole 521 are provided on both sides of the slider 73. The bidirectional lead screw 72 is rotatably mounted on the turntable 51 via a fixing rod 721, and its two ends are threaded through the two sliders 73 respectively. The drive motor 71 is mounted on the injection molding machine. A drive gear is coaxially mounted on the output shaft of the drive motor 71, and a driven gear is coaxially mounted in the middle of the bidirectional lead screw 72. The drive gear and the driven gear mesh.

[0028] The drive motor 71 is started. Through the engagement of the drive gear and driven gear, the drive motor 71 drives the bidirectional lead screw 72 to rotate. When the bidirectional lead screw 72 rotates, it causes the slider 73 to move along the sliding hole 521. Since the slider 73 has cylindrical rods 74 on both sides and the position of the bidirectional lead screw 72 is fixed, the slider 73 can rotate at a corresponding angle when it moves. Simultaneously, the slider 73's movement causes the two pick-and-place rods 52 to rotate closer or further apart, facilitating their rotation. When the two pick-and-place rods 52 rotate to a near-straight state, the pick-and-place components 6 on the two rods 52 are respectively aligned with the injection cavity on the lower mold and the receiving frame 22 near the injection molding machine. This allows for simultaneous picking of the connectors to be processed and those already processed. The two pick-and-place rods 52 are then driven to rotate closer together, and the rotating component 8 drives the turntable 51 to rotate 180°, completing a new round of feeding and unloading.

[0029] Reference Figure 3The pick-and-place component 6 includes a second suction cup 61 and an air pump 62. The second suction cup 61 is located at the end of each pick-and-place rod 52, and is positioned on one side of the two pick-and-place rods 52 facing away from each other. The air pump 62 is located on the other side of the pick-and-place rods 52 and is connected to multiple second suction cups 61. The rotating component 8 includes a rotating motor 81, which is embedded inside the injection molding machine. The output shaft of the rotating motor 81 extends vertically upwards and extends upwards to the outside of the injection molding machine, connecting to the turntable 51.

[0030] The implementation principle of the loading and unloading device for a vehicle-mounted connector injection molding machine according to an embodiment of this application is as follows: multiple conveyor devices 2 are driven to move by a conveyor belt 1. When the conveyor device 2 with the connector to be processed moves to the opposite side of the injection molding machine, the pick-and-place device 3 removes the connector from the conveyor device 2 and conveys it to the lower mold. At the same time, the pick-and-place device 3 also removes the connector that has been injection molded from the lower mold and conveys it to the conveyor device 2. When the conveyor device 2 with the processed connector moves to the side away from the injection molding machine, the conveyor device 2 removes the connector and drops it into the collection frame 9. Meanwhile, the operator places the connector to be processed in the empty conveyor device 2. Thus, the operator does not need to manually load and unload the connector on the lower mold, reducing the safety risks in the production process.

[0031] Finally, it should be noted that in the description of this application, the terms "vertical," "upper," "lower," "horizontal," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.
