Description

Technical Field

[0001] This utility model relates to the field of static electricity elimination technology for housings, specifically a static electricity elimination device for automotive lamp housings after injection molding. Background Technology

[0002] The existing Chinese patent document CN219204760U discloses an antistatic device for automotive injection molded parts, including a base box. An antistatic chamber is bolted to the top outer wall of the base box. The antistatic chamber contains an antistatic assembly, which includes a wire, a connecting rod, an elastic hose, and a conductive roller. The conductive roller contacts the injection molded part to remove static electricity. Simultaneously, airflow from inside the elastic hose enters the conductive roller and exits through a through-hole in the outer wall of the conductive roller, blowing away dust from the injection molded part. An output assembly includes a rigid pipe, a support column, and an air pump. The air pump allows airflow to enter the elastic hose through the connecting rigid pipe. This invention can achieve both antistatic and dust removal for injection molded parts through the antistatic assembly. The base box also contains a placement assembly, which includes a second electric push rod and a placement plate. Opening the second electric push rod causes the placement plate to move longitudinally, allowing the injection molded part to contact the antistatic assembly. This device is suitable for injection molded parts of different sizes.

[0003] However, in practical applications, during the injection molding process of automotive lamp housings, debris, particles, and other impurities are easily left on the surface. Existing technologies lack cleaning components for the surface of the housing after injection molding before static electricity removal, making it impossible to effectively clean the housing before static electricity removal. These residual debris not only affect the full contact between the static electricity removal device and the housing, reducing the static electricity removal effect, but may also re-adhere to the housing surface due to electrostatic adsorption, interfering with subsequent production processes and potentially affecting the processing quality and production efficiency of the automotive lamp housing.

[0004] Therefore, this utility model proposes an anti-static device after injection molding of vehicle lamp housing to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this utility model is to provide an anti-static device after injection molding of a vehicle lamp housing, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a static eliminator after injection molding of a vehicle lamp housing, comprising a conveyor belt, a box, and a support base, wherein the support base is fixed on both sides of the conveyor belt, and the box is fixedly disposed on the outside of the support base;

[0007] The conveyor belt is equipped with an antistatic component, a cleaning component, and a snap-fit ​​component. The antistatic component is fixedly installed on one end of the box, the cleaning component is fixedly installed on both sides of the support base, and the snap-fit ​​component is installed on the cleaning component.

[0008] Preferably, the bottom end of the fixing rod in the static elimination assembly is fixedly provided with an air blowing port, the fixing rod is slidably embedded in the end of the box, and the air blowing port is driven by a driving device.

[0009] Preferably, the second fixing rod in the cleaning assembly is fixedly disposed on both sides of the support base, and sliding grooves are provided at both ends of the second fixing rod.

Detailed Implementation

[0019] The technical solutions in the embodiments of this utility model will be clearly and completely described below. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Example 1: Please refer to Figures 1-2 An antistatic device for injection molding of vehicle headlight housing includes a conveyor belt 1, a box 2, and a support base 3. The support base 3 is fixed on both sides of the conveyor belt 1, and the box 2 is fixedly installed on the outside of the support base 3. An antistatic component 4, a cleaning component 5, and a snap-fit ​​component 6 are provided on the conveyor belt 1. The antistatic component 4 is fixedly installed on one end of the box 2, the cleaning component 5 is fixedly installed on both sides of the support base 3, and the snap-fit ​​component 6 is installed on the cleaning component 5.

[0021] The bottom end of the fixing rod 401 in the static elimination component 4 is fixedly provided with an air outlet 402. The fixing rod 401 is slidably embedded in the end of the box 2, and the air outlet 402 is driven by a driving device.

[0022] In use, the headlight housing is placed on the conveyor belt 1 and moves with the conveyor belt 1. When the housing moves to the bottom of the static elimination component 4, the drive device is started, which drives the air nozzle 402 to slide and adjust its height at the end of the housing 2 via the fixing rod 401, so that the air nozzle 402 maintains a suitable distance from the headlight housing and blows out an ionized airflow to eliminate static electricity from the housing. By adjusting the sliding of the fixing rod 401, it can adapt to headlight housings of different heights, ensuring that the static elimination component 4 can efficiently and comprehensively eliminate static electricity from all parts of the housing, and avoid the impact of static electricity residue on subsequent processes.

[0023] Example 2: Based on Example 1, please refer to... Figures 2-3 The second fixing rod 501 in the cleaning component 5 is fixedly installed on both sides of the support base 3, and sliding grooves 502 are provided at both ends of the second fixing rod 501.

[0024] A cleaning protrusion 503 is slidably embedded in the sliding groove 502 of the cleaning component 5, and a cleaning brush 504 is evenly arranged on the cleaning protrusion 503.

[0025] In use, when the headlight housing is conveyed to the cleaning assembly 5 on the conveyor belt 1, the cleaning protrusion 503 moves up and down along the sliding grooves 502 on both sides of the second fixed rod 501 under the drive of the hydraulic telescopic rod 505, so that the cleaning brush 504 fits against the surface of the housing. As the housing moves, the cleaning brush 504 cleans and removes the debris, particles and other impurities remaining on the surface of the housing. The sliding groove 502 can ensure that the cleaning protrusion 503 slides smoothly, ensuring that the cleaning brush 504 can continuously and effectively contact the housing during the cleaning process, improving the cleaning effect and creating clean surface conditions for subsequent static electricity removal.

[0026] Example 3: Based on Example 2, please refer to... Figures 3-4 The cleaning protrusion 503 in the cleaning assembly 5 is fixedly mounted on the hydraulic telescopic rod 505, and the hydraulic telescopic rod 505 is fixedly mounted inside the second fixed rod 501.

[0027] The snap-fit ​​protrusion 601 in the snap-fit ​​assembly 6 is slidably embedded in the snap-fit ​​groove 602. The snap-fit ​​groove 602 is located at one end of the cleaning protrusion 503, and the snap-fit ​​protrusion 601 is fixedly mounted on the side brush 603.

[0028] In use, the snap-fit ​​assembly 6 plays a role in removing impurities from the side gaps of the headlight housing. The side brush 603 is snapped and fixed by the snap-fit ​​protrusion 601 and the snap-fit ​​groove 602 on the sweeping protrusion 503. The hydraulic telescopic rod 505 drives the sweeping protrusion 503 to move the side brush 603 to the appropriate position. The side brush 603 can perform targeted cleaning on the side. If it is necessary to replace the side brush 603 with a different specification, it can be quickly disassembled and assembled by separating the snap-fit ​​protrusion 601 and the snap-fit ​​groove 602 to meet the cleaning needs of housings with different shapes, and further improve the comprehensiveness and flexibility of the device's cleaning.
