Description

Technical Field

[0001] The utility model relates to the technical field of equipment cleaning, and particularly relates to an in-mold defect detection device for injection molding. Background Technique

[0002] An injection molding machine, also known as an injection molding machine or an injection machine, is the main molding equipment for making various shaped plastic products from thermoplastic or thermosetting plastics using plastic molding dies. When using an injection molding die, it is necessary to detect the inside of the die cavity through a detection device. However, most of the existing detection devices are directly installed on one side of the injection molding machine, and the detection angle is adjusted to facilitate the detection of the inside of the die cavity. Moreover, the detection environments of the existing detection devices are divided into two situations. One is the detection device in a dust-free environment. When detecting the inside of the die cavity, there will be no dust accumulating on the lens of the detection device due to long-term use, which reduces the detection effect of the detection device on the inside of the die cavity. However, the cost of the dust-free working environment is relatively high, and the staff needs to wear work clothes and other operations are relatively cumbersome. The other is the detection device in a normal environment. When detecting the inside of the die cavity, it is necessary to frequently clean the lens of the detection device with a dust-free cloth during long-term use to avoid dust accumulating on the lens and affecting the use of the detection device. However, when frequently detecting the detection device, the situation of forgetting to clean the detection device may occur. On the one hand, frequently cleaning the detection device is time-consuming and laborious. On the other hand, when forgetting to clean the detection device, the detection of the inside of the die cavity by the detection device may deviate.

[0003] Chinese Patent with Publication Number CN218282804U discloses an in-mold detection device for an injection molding machine, including a detection mechanism arranged on one side of the injection molding machine body through a support component. The detection mechanism includes a box body arranged at a position on one side of the injection molding machine body, a detection camera arranged in a detection slot opened at one end of the box body through an adjustment component, a cleaning component arranged in the detection slot and used for cleaning the lens of the detection camera, and a partition component arranged in the detection slot and sleeved on the cleaning end of the cleaning component.

[0004] For the above disclosed technology, the surface of the in-mold detection camera of the injection molding machine often needs to be wiped to remove dust during use. In the above disclosed technology, after the dust-free cloth cleans the detection camera, dust on the detection camera will adhere to its surface, thus affecting the cleaning quality of the dust-free cloth for the detection camera next time. Summary of the Utility Model

[0005] To make up for the above deficiencies, the utility model provides an in-mold defect detection device for injection molding.

[0006] The utility model is implemented as follows:

[0007] An in-mold defect detection device for injection molding, comprising a support mechanism, a detection mechanism, and a cleaning mechanism. The support mechanism supports the detection mechanism and adjusts the height of the detection mechanism. The detection mechanism includes a detection box and a first driving mechanism. A detection cavity is provided on one side of the detection box, and a macro camera is provided inside the detection cavity. The first driving mechanism drives the macro camera to move horizontally. The cleaning mechanism includes a cleaning box, a second driving mechanism, and a third driving mechanism. A cleaning cavity is provided inside the cleaning box, and the cleaning box is installed on the outside of the detection box. A cleaning member is provided inside the cleaning cavity. The second driving mechanism drives the cleaning member to move horizontally and makes the top of the cleaning member wipe the lens of the macro camera. The output end of the third driving mechanism is connected to a clapper board located inside the cleaning cavity, and the clapper board beats the top of the cleaning member. Installation windows connected to the cleaning cavity are provided on both sides of the cleaning box, and fixing plates are respectively connected by bolts inside the installation windows. An anode plate and a cathode column are respectively installed on one side of a pair of the fixing plates close to each other.

[0008] Further, the third driving mechanism includes a motor, an eccentric wheel, a connecting plate, a connecting column, and a first spring. The motor is installed on the top of the cleaning box, and the output end of the motor is in transmission connection with the eccentric wheel. A slot connected to the cleaning cavity is provided on the top of the cleaning box. The connecting column slides inside the slot. The connecting plate is installed at the top end of the connecting column, and the clapper board is installed at the bottom end of the connecting column. Both ends of the first spring are respectively connected to the bottom of the connecting plate and the top of the cleaning box, and the eccentric wheel presses the bottom of the connecting plate.

[0009] Further, an opening connected to the cleaning cavity is provided on one side of the cleaning box, and a sliding groove connected to the detection cavity is provided on one side of the detection box, and the sliding groove is connected to the opening. The second driving mechanism is a second electric telescopic rod, and the second electric telescopic rod is installed on the outside of the cleaning box. The telescopic end of the second electric telescopic rod is connected to the cleaning member, and the cleaning member slides into the detection cavity through the opening and the sliding groove.

[0010] Further, the cleaning member includes a cleaning seat, and a groove is provided on the top of the cleaning seat, and a dust-free cloth is installed inside the groove.

[0011] The beneficial effects of adopting the above further solution are as follows: The second electric telescopic rod is used to drive the cleaning member to move, so that it slides into the detection cavity through the opening and the chute. The dust-free cloth on its top will rub against the lens of the macro camera and wipe the lens of the macro camera. After the wiping is completed, the cleaning member will move to the cleaning cavity. The motor drives the eccentric wheel to periodically squeeze the bottom of the connecting plate. Under the action of the first spring, the connecting column will periodically rise and fall, so that the clapper will periodically beat the dust-free cloth, thereby discharging the dust on the surface of the dust-free cloth into a suspended state. Since a high-voltage electrostatic field is formed between the grounded anode plate and the energized cathode column, the dust suspended in the air will combine with negative ions, discharge to the anode plate and deposit, so as to remove the dust on the dust-free cloth.

[0012] Further, the first driving mechanism includes a first electric telescopic rod, a sliding plate, and a cross bar. The first electric telescopic rod is installed outside the detection box. The telescopic end of the first electric telescopic rod is connected to the sliding plate. The sliding plate is connected to the cross bar, and the sliding plate slides in the detection cavity.

[0013] Further, a pair of limiting rods are installed inside the detection cavity. Limiting plates are installed at one ends of the pair of limiting rods. A pair of limiting grooves are provided on the outer side of the sliding plate. The limiting rods slide in the limiting grooves, and the limiting plates block the sliding plate.

[0014] Further, a sliding rod is installed at the bottom of the cross bar, and a sliding sleeve is installed at the top of the macro camera. The sliding rod slides in the sliding sleeve, and a second spring is connected between the macro camera and the cross bar.

[0015] The beneficial effects of adopting the above further solution are as follows: The first electric telescopic rod drives the sliding plate to move, so that the macro camera extends out of the detection box. Its downward-facing lens will take pictures of the mold cavity in the mold, and the obtained images will be reflected on the monitoring screen. The inspector can know whether there are cracks or other conditions in the mold cavity through the images, so as to obtain the detection results of the mold cavity in the mold.

[0016] The beneficial effects of adopting the above further solution are as follows: The second spring enables the macro camera to have a certain amount of telescopic ability. At the same time, the sliding rod and the sliding sleeve ensure that the macro camera can slide vertically. In this way, the dust-free cloth can be squeezed against the lens of the macro camera, ensuring the wiping effect of the dust-free cloth on the lens of the macro camera.

[0017] Further, a connecting frame is installed on one side of the detection box. Connecting grooves are provided on the top and the inner wall of the connecting frame. A baffle slides in the connecting groove, and a handle is installed on the top of the baffle.

[0018] The beneficial effect of adopting the above further solution is that by placing the baffle plate inside the connection box, the detection cavity can be blocked to prevent external dust from entering the detection cavity.

[0019] Further, the support mechanism includes a base, a connection sleeve, a threaded ring, and a threaded rod. The connection sleeve is installed at the center of the top of the base. The threaded ring is rotatably installed on the top of the connection sleeve. The threaded rod slides inside the connection sleeve and is threadedly engaged with the threaded ring. The top end of the threaded rod is connected to the detection box.

[0020] The beneficial effect of adopting the above further solution is that by rotating the threaded sleeve and combining with the self-weight of the threaded rod and the components installed on its top, the threaded rod will not rotate synchronously with the threaded sleeve but move up and down as the threaded sleeve rotates, so as to change the height of the macro camera and enable it to meet different usage situations.

[0021] The beneficial effect of the present utility model is as follows: An in-mold defect detection device for injection molding obtained by the above design of the present utility model uses a second electric telescopic rod to drive the cleaning member to move, so that it slides into the detection cavity through the opening and the chute. The dust-free cloth on its top will rub against the lens of the macro camera and wipe the lens of the macro camera. After the wiping is completed, the cleaning member will move into the cleaning cavity. The motor drives the eccentric wheel to periodically squeeze the bottom of the connecting plate. Under the action of the first spring, the connecting column will periodically move up and down, so that the clapper will periodically beat the dust-free cloth, thereby discharging the dust on the surface of the dust-free cloth into a suspended state. Because a high-voltage electrostatic field is formed between the grounded anode plate and the energized cathode column, the dust suspended in the air will combine with negative ions and discharge and deposit on the anode plate, so as to remove the dust on the dust-free cloth.
