[0001] The invention relates to the technical field of component detection, and in particular to a detection device for automobile components after injection molding. Background Art

[0002] In the production process of automotive parts, injection molding is a common manufacturing method used to produce plate-type parts of various shapes and sizes. These parts need to undergo rigorous quality inspections before being assembled into the car to ensure that they meet safety and performance standards. Traditional inspection methods usually rely on manual inspections or simple mechanical devices, which are not only inefficient but also easily affected by the operator's subjective judgment, making it difficult to ensure the accuracy and consistency of the inspection results.

[0003] With the development of automation technology, more and more companies are beginning to use automated testing equipment to improve production efficiency and product quality. However, when performing tests, such as anti-deformation testing, existing automated testing equipment requires cumbersome loading and unloading processes, and the testing efficiency is low.

[0004] After searching, the application scheme of Chinese patent application number CN202321494994.8 discloses an anti-bending detection device for automobile parts, including a base, a connecting frame fixedly connected to the top of the base, a hydraulic press fixedly connected to the top of the connecting frame, two clamping frames slidably connected to the base, a bottom plate fixedly connected to the clamping frame, a moving plate slidably connected to the clamping frame, and a sliding frame fixedly connected to a first spring.

[0016] The beneficial effects of the present invention are: 1. The present invention can place the plate-type component to be detected on the carrier by setting a carrier assembly and a detection mechanism. When it moves to the detection position, based on the operation of the lifting control assembly, it drives the pressure plate to press the plate-type component downward. If the plate-type component is deformed, its two ends will rise upward, thereby squeezing the pressure sensor assembly, and using the pressure sensor assembly to detect the force deformation of the plate-type component.

[0019] 4. The present invention sets a guide assembly, which can enable the ball head rod to move into the channel between the two guide frames during the movement of the chain conveying mechanism. Since the width of the channel is smaller than the diameter of the ball body of the ball head rod and the guide frame is in a "J" shape, the ball head rod can be gradually pulled apart to both sides, thereby releasing the fixing effect on the plate-type components and avoiding possible deformation of the plate-type components during the detection process, thereby improving the reliability of the detection. The fixing and releasing are automatically switched through the movement of the chain conveying mechanism, without the need for an additional electrical control structure, and have high reliability and low cost.
