AI Technical Summary
In existing technology, the lampshade cannot be demolded after being placed in the tooling, resulting in a slow cycle of lampshade masking action before spraying, especially in the negative angle area where it cannot be effectively covered, affecting production efficiency.
A flip-type spray masking fixture was designed, which uses a contour jig and a flipping component. The contour jig includes a basic contour component and a flipping block. By lifting the lifting plate and flipping the flipping component, the negative angle part of the lampshade is enveloped, avoiding interference and ensuring that the lampshade can be inserted and removed straight up and down.
The increased speed of the internal blocking action of the lampshade avoided interference, ensuring a smooth spraying process and improving production efficiency.

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of automotive lamp manufacturing technology, specifically a flip-type spray masking fixture. Background Technology
[0002] In the production of UV-cured lampshades, it is usually necessary to mask the inside of the lampshade to prevent paint drift, meaning that only the outside of the lampshade needs to be painted. However, in cases where the lampshade cannot be demolded after being placed in the fixture (because the lampshade has a negative angle section, i.e., a structure that is wider at the bottom and narrower at the top), a push-pull cylinder is required to push the fixture to partially mask the lampshade, affecting the production cycle. Specifically, because there is a negative angle at the bottom of the outer periphery of the lampshade, the lampshade cannot be inserted into a fixture that can cover the bottom of the outer periphery of the lampshade in a straight up-down manner. If the negative angle of the lampshade requires the fixture to have a structure that is wider at the top and narrower at the bottom to cover it, the structure of the fixture that is wider at the top and narrower at the bottom will interfere with the straight up-down movement of the lampshade. Summary of the Invention
[0003] In order to solve the technical problem in the prior art that the lampshade cannot be demolded when placed in the tooling, resulting in a slow cycle of the lampshade masking action before spraying, this application proposes a flip-type spraying masking tooling, which solves the above-mentioned technical problem.
[0004] The technical solution adopted by this utility model to solve its technical problem is:
[0005] This utility model provides a flip-type spray masking fixture, comprising: a base frame, on which a lifting plate and a flipping assembly are disposed, the flipping assembly including a bracket connected to the base frame and located outside the lifting plate, a flipping element disposed on the bracket, the first end of the flipping element being rotatably connected to the bracket via a rotating shaft, a drive rod hinged to the middle section of the flipping element, the drive end of the drive rod being hinged to the flipping element, and the force-bearing end of the drive rod being hinged to the lifting plate, so that the lifting plate drives the flipping element to flip while lifting and lowering; and a contour jig, the contour jig being used to receive and enclose a lampshade, the contour jig including a basic contouring assembly and a flipping block overlapping the basic contouring assembly, the basic contouring assembly enclosing the lampshade at a positive angle, including a fixing block fixed to the base frame and lifting blocks disposed at both ends of the fixing block, the lifting blocks being fixed to the lifting plate and rising and falling with the lifting plate, the flipping blocks being fixed to the second end of the flipping element and flipping as the lifting plate descends to enclose the lampshade at a negative angle.
[0006] Furthermore, the base frame includes a mounting base plate, on which a guide sleeve is fixed. A liftable guide column is fitted inside the guide sleeve. One end of the guide column is fixedly connected to the lifting plate, and the other end of the guide column is driven by a driving device to achieve lifting action.
[0007] Furthermore, a vertically upward-extending support plate is fixed on the mounting base plate, and the fixing block is fixedly connected to the mounting base plate through the support plate.
[0008] Furthermore, an air collecting block is installed on the support plate, and an air inlet is connected to the air collecting block.
[0009] Furthermore, a handle is also fixed to the mounting base plate.
[0010] Furthermore, a vertically upward-extending T-shaped plate is fixed on the lifting plate, and the lifting block is fixedly connected to the lifting plate through the T-shaped plate.
[0011] Furthermore, a horizontal tube is fixed on the lifting block, and the force-bearing end of the drive rod is hinged to the end of the horizontal tube.
[0012] Furthermore, a shielding plate is provided at the joint between the lifting block and the fixed block to cover the seam, and the shielding plate is fixed on the lifting block.
[0013] Based on the above technical solution, the technical effects that this utility model can achieve are as follows:
[0014] This utility model discloses a flip-type spray masking fixture. A contour jig is used to receive and enclose a lampshade. The contour jig includes a basic contouring component and a flipping block overlapping the basic contouring component. The basic contouring component encloses the lampshade at its positive angle and includes a fixing block and a lifting block. Initially, the lifting block is in a raised state, and the flipping block is in a flipped state. After the lampshade is placed onto the lifting block, it descends together with the lifting block until the lifting block and the fixing block are joined. The basic contouring component covers the positive angle portion of the lampshade's outer bottom periphery. During the enveloping process, the flipping block is driven by the lifting block and gradually flips onto the lampshade. While not interfering with the lampshade's insertion, it envelops the negative angle area of the lampshade's outer periphery. After the spraying is completed, the lifting block lifts the lampshade, and the flipping block flips out from the negative angle area of the lampshade as the lifting block rises. This does not interfere with the lampshade's removal, allowing the lampshade to be placed into the contour jig in a straight up-and-down manner, completely enveloping the bottom periphery of the lampshade to prevent paint drift, thereby accelerating the pace of the internal masking action of the lampshade.
