Description

Technical Field

[0001] The present application relates to the field of injection molded part detection devices, and more specifically, to an injection molded part flatness detection device. Background Art

[0002] Injection molded parts refer to various injection products produced by injection molding machines, including various packages, parts, etc. They are mainly made of materials such as polyethylene or polypropylene and added with a variety of organic solvents. Some parts of automobiles are made by injection molding. After the automobile injection molding parts are processed, flatness detection is required.

[0003] Some existing injection molded parts flatness detection devices manually place the injection molded parts in the frame on a conveyor belt and transport them to the bottom of the detection device for detection through the conveyor belt. They do not have the function of automatic loading, which reduces the detection efficiency of the equipment and increases the workload of the staff. Therefore, in order to solve the above problems, we propose an injection molded parts flatness detection device. Utility Model Content

[0004] In order to solve the above problems, the present application provides an injection molded part flatness detection device, which adopts the following technical solution:

[0006] By adopting the above technical scheme, when the equipment is in use, the staff will carry the frame with the injection molded parts to the front of the frame, and then clamp the injection molded parts through the clamping assembly. Then, the driving assembly drives the support block to slide in the support box, and the support block moves synchronously with the clamping assembly and the injection molded parts, so as to play the role of conveying and loading. There is no need for the staff to manually load the materials, which is beneficial to improve the subsequent detection effect of the equipment. When the injection molded parts are on the conveyor belt, the injection molded parts are transported to the protective frame through the conveyor belt. The protective frame is provided with a detection assembly, which can play the role of detecting the flatness of the injection molded parts. When the injection molded parts are transported on the conveyor belt, the correction assembly is operated to play the role of clamping and correcting the position of the injection molded parts on the conveyor belt, which helps to avoid the displacement of the injection molded parts during transportation. Then, when the injection molded parts are qualified, they are transported away through the conveyor belt. When there are unqualified injection molded parts, a signal is given to the pushing assembly through the console, and the unqualified injection molded parts are pushed away from the conveyor belt by the pushing assembly, which can play the role of sorting products.

[0007] Furthermore, the detection component includes a laser scanner fixedly mounted on the inner wall of the top end of the protection frame, a mounting frame is fixedly mounted on the inner wall of the top end of the protection frame, and a three-coordinate measuring instrument is provided on the mounting frame.

[0008] By adopting the above technical solution, a laser scanner is provided in the protective frame to scan the information of the injection molded parts, and a three-coordinate measuring instrument is used in the protective frame to further measure the flatness of the injection molded parts, which is convenient for the staff to compare data and is beneficial to improving the accuracy of equipment measurement.

[0010] By adopting the above technical solution, the electric clamp is driven by the telescopic rod to move down into the frame, and then the injection molded part is clamped by the electric clamp to grasp the injection molded part. The inner wall of the electric clamp is provided with a rubber pad to protect the injection molded part.

[0011] Furthermore, the driving assembly includes a screw rod rotatably installed in a support box, the support block is sleeved on the side wall of the screw rod, a mounting box is fixedly installed on one side of the support box, and a reduction motor is fixedly installed in the mounting box, the screw rod passes through the mounting box on the side away from the protective frame and is fixedly connected to the output shaft of the reduction motor, sliders are fixedly installed on both sides of the support block, and a sliding groove matching the slider on the same side is opened on the inner wall of the support box.

[0012] By adopting the above technical scheme, after the electric gripper grabs the injection-molded part, the electric gripper and the injection-molded part are driven to rise through the telescopic rod, and then the screw is driven to rotate through the reduction motor. Since the support block is sleeved on the side wall of the screw, when the screw rotates, the support block is driven to slide in the support box, and the support block moves synchronously with the telescopic rod, the electric gripper and the injection-molded part, so that the injection-molded part moves to the top of the conveyor belt, and the electric gripper and the injection-molded part are driven to descend synchronously through the telescopic rod. Then, the electric gripper is released to play the role of loading. Then, the reduction motor rotates in the opposite direction to make the electric gripper move to the top of the frame, so as to clamp the injection-molded part again and load the material again. There is no need for manual loading by the staff, which is beneficial to improving the detection efficiency of the equipment.

[0013] Furthermore, the correction assembly includes a first cylinder fixedly installed on opposite sides of two support plates, the two first cylinder piston shafts slide through the same support plate, and the ends of the two first cylinder piston shafts are fixedly installed with installation frames, and correction rollers distributed in a linear array are rotatably installed in the two installation frames.

[0014] By adopting the above technical scheme, when the conveyor belt conveys the injection molded parts, the first cylinder drives the same group of mounting frames and correction rollers to move, and the cooperation of the two groups of correction rollers can play a role in clamping and positioning the injection molded parts, and then play a role in correcting the conveying position of the injection molded parts, which helps to avoid the displacement of the injection molded parts during the conveying process, and the correction rollers are rotatably installed in the mounting frame, which can play a role in limiting the injection molded parts without affecting the subsequent movement of the injection molded parts.

[0015] Furthermore, two symmetrically distributed limiting rods are fixedly installed on opposite sides of the two installation frames, and the two limiting rods in the same group are slidably penetrated through the support plates in the same group on the side away from the installation frame on the same side.

[0016] By adopting the above technical solution, when the first cylinder drives the same group of installation frames to move, the installation frames move with the same group of limiting rods. The setting of the limiting rods can limit and stabilize the installation frames, which is conducive to maintaining the stability of the movement of the installation frames.

[0017] Furthermore, the pushing assembly includes a second cylinder fixedly mounted on the outer side of the support plate, the piston shaft of the second cylinder slides through the support plate, and a push plate is fixedly mounted on the end of the piston shaft of the second cylinder, a baffle is fixedly mounted on the inner side of one end of the push plate away from the protective frame, and a sliding plate is fixedly mounted on one side of the frame at an angle.

[0018] By adopting the above technical solution, when there are unqualified injection molded parts, the push plate is driven by the second cylinder to move on the conveyor belt, and the unqualified injection molded parts are pushed into the sliding plate by the push plate, so that the unqualified products can be discharged and the sorting effect can be achieved. In addition, the baffle plate is set on the inner side of the push plate to block the unqualified injection molded parts from moving forward, making it easier for the push plate to push out the unqualified injection molded parts.
