Description

Technical Field

[0001] This utility model relates to the field of mechanical technology, specifically to a clamping and transferring device for injection molded parts. Background Technology

[0002] Injection molding is a core process for mass production of plastic parts, widely used in the automotive, electronics, and home appliance industries. After demolding, injection molded parts need to be quickly transferred to subsequent processes (such as assembly, inspection, or packaging). Traditional manual transfer is inefficient, costly, and prone to product damage due to improper handling.

[0003] Currently, robotic arms are used to transfer injection molded parts over short distances. However, most robotic arms on the market can only complete a fixed stroke of movement. For different products, the grippers need to be raised and lowered at different heights, which is difficult to adjust with traditional transfer devices.

[0004] Therefore, it is of great significance to provide a clamping and transfer device for injection molded parts to solve the problems existing in the prior art. Utility Model Content

[0005] In view of this, the purpose of this application is to provide an injection molded part clamping and transfer device to solve the problem that most of the transfer robots on the market can only complete a fixed stroke of movement, but for different products, the grippers need to be raised and lowered at different heights, which is difficult to adjust with traditional transfer devices.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A clamping and transferring device for injection molded parts includes a fixed plate, wherein side plates and side frames are fixedly connected to the two sides of the top and bottom of the front of the fixed plate, respectively.

[0008] An eccentric rotating rod is rotatably connected between the two side plates. The middle part of the eccentric rotating rod is recessed. A smooth rod is fixedly connected between the two side frames. A slide block is slidably connected to the smooth rod. A sliding sleeve is fixedly connected to the front of the slide block. A slide rod is slidably connected to the sliding sleeve. A fisheye bearing and a gripper are respectively installed at the top and bottom of the slide rod. The top of the fisheye bearing is in contact with the surface of the eccentric rotating rod. The fisheye bearing and the slide block are elastically connected by a spring.

[0009] Preferably, a third motor is mounted on the outer side of the side plate, and the output shaft of the third motor is connected to the eccentric rotating rod via a transmission connection.

[0010] Preferably, a second motor is installed on the outer side of the side frame, and the output end of the second motor is connected to a lead screw, which is threadedly connected to the slide block.

[0011] Preferably, the clamp includes a fixed block, and side blocks are fixedly connected to both sides of the front of the fixed block. A sliding groove is provided on the back of the fixed block, and two clamping plates are slidably connected in the sliding groove. A first motor is installed on the outer side of the side block, and a lead screw is driven to the output end of the first motor. The lead screw includes two opposite threads, and the two clamping plates are respectively threaded to the two threads.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] In use, the second motor drives the lead screw to rotate, which in turn drives the slide to slide left and right. When the slide reaches the far right of the guide rod, the gripper is positioned at the top of the product. Then, the third motor drives the eccentric rotating rod to rotate. The eccentric rotating rod, through a fisheye bearing, presses the slide downwards, positioning the gripper's clamping plates on either side of the product. The first motor then drives the clamping plates to hold the product via the lead screw. The eccentric rotating rod then rotates, causing the gripper to lift the product. The gripper then slides to the side, rotating 180 degrees during this process. When the gripper reaches the middle section, the product is lifted to a certain height. Once the product is transferred to the desired position, the eccentric rotating rod rotates again, causing the slide to lower the gripper, opening it and releasing the product. The gripper then rises. Compared to existing transfer devices, the gripper in this invention can flexibly lift, lower, and slide left and right, resulting in low operating costs and a simple structure.

[0026] A third motor 16 is installed on the outer side of the side plate 17. The output shaft of the third motor 16 is connected to the eccentric rotating rod 2. The third motor 16 drives the eccentric rotating rod 2 to rotate 180 degrees each time.
