Description

Technical Field

[0001] The utility model belongs to the technical field of inspection tools and measuring tools, and in particular relates to a detection component for spring missing installation. Background Art

[0002] During the production and assembly process of the nozzle, in order to adjust the internal pressure of the nozzle and the injection flow rate of the nozzle, the production staff will install a spring in the nozzle body to adjust the pressure. The installed spring usually needs to be inspected for problems such as deviation, missing installation, and overlap, and then the nozzle body with the spring installed is transported to the next process using a conveyor belt.

[0003] At present, when inspecting the spring position, employees usually rely on their naked eyes to check for missing springs. Therefore, this method mainly relies on the proficiency of the inspectors, and is greatly affected by human factors. At the same time, this inspection method will gradually reduce the inspection efficiency as the number of nozzle bodies to be inspected increases, and will also cause fatigue damage to the workers' eyes, resulting in missed inspections and wrong inspections. Utility Model Content

[0004] In view of this, the utility model provides a detection component for missing springs, the purpose of which is that, through the arrangement of a transmission chassis, an IV camera, a sensor module and a turntable jig, a worker can place the side of the nozzle body on the turntable jig with the spring installed facing the IV camera, and then scan and photograph the nozzle body through the lens of the IV camera, and then the image sensor can compare the photographed photo with the normal installation photo in the storage module, and judge whether the spring is installed in the nozzle body as required by the comparison matching degree, and then when the matching degree of the picture is low, the turntable jig can be controlled by the sensor module, so that the turntable jig can push unqualified products into the NG material box, thereby eliminating the need for workers to detect with their naked eyes, thereby improving the detection quality and efficiency while saving labor costs.

[0005] The technical solution adopted by the utility model is as follows:

[0006] A detection component for missing springs, comprising a cabinet, wherein the cabinet comprises a transmission chassis, a sensor module, a turntable jig and an NG material box, wherein the transmission chassis is vertically arranged on the top of the cabinet, and the sensor module is horizontally placed on the top of the cabinet where the transmission chassis and the cabinet are connected to each other, the turntable jig is fixed on the top of the sensor module, an IV camera is provided on the top of the transmission chassis, and the IV camera comprises an image sensor arranged inside, a storage module and a lens arranged on one side of the turntable jig, and the NG material box is fixed on the top of the cabinet and distributed in parallel on one side of the turntable jig.

[0007] As a preferred technical solution, the turntable fixture includes a turntable, a rotating shaft and a driver distributed from top to bottom, and two material discharge troughs are provided on the side of the turntable facing the IV camera. The two material discharge troughs are distributed in parallel on both sides of the turntable with opposite opening directions, and a card slot is provided inside the material discharge trough, and a horizontal card plate is provided on the inner wall where the card slot and the material discharge trough intersect.

[0008] Furthermore, a push ring is provided on the side of the slot away from the opening, and lifting rods are provided on both sides of the push ring. A lifting cylinder is provided inside the turntable, and the side of the lifting rod away from the push ring is inserted into the lifting cylinder.

[0009] Furthermore, the lens of the IV camera is distributed in parallel just above one of the material discharge troughs on the top of the turntable fixture, and a guide groove and an NG material box fixedly connected to the guide groove are provided in the opening direction of the material discharge trough.

[0010] Furthermore, a data cable is provided between the IV camera and the transmission chassis.

[0011] Furthermore, the sensing module includes sensors, and the sensors are respectively connected to the transmission chassis and the driver and lifting cylinder in the turntable fixture.

[0012] Furthermore, the push ring is movably fitted inside the slot, and the openings of the push ring and the slot face the same direction, and the opening of the push ring is located in the middle of the inner wall of the slot.

[0013] Furthermore, the guide groove is arranged at an inclined angle so that a triangular structure is formed between the guide groove, the turntable fixture and the NG material box, and the end of the guide groove away from the NG material box is in a fit with the opening of the discharge trough.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0015] 1. Through the setting of the transmission chassis, IV camera, sensor module and turntable fixture, the worker can place the side of the nozzle body with the spring installed facing the IV camera on the turntable fixture, and then scan and photograph the nozzle body through the lens of the IV camera. The image sensor can then compare the photographed photo with the normal installation photo in the storage module, and judge whether the spring is installed in the nozzle body as required by the comparison match. When a picture with a low match appears, it means that the spring is not installed in the nozzle body as required. At this time, the transmission chassis will transmit the signal of unqualified inspected products to the sensor module, so that the sensor module controls the turntable fixture to push the unqualified products into the NG material box.

[0016] 2. Through the setting of the lifting cylinder and the push ring, when the sensor module receives the signal of unqualified products, it will feed back the signal to the lifting cylinder, so that the lifting cylinder can drive the lifting rod to move the push ring. Then, the push ring can push the nozzle body placed in the discharge trough into the NG material box under the push of the lifting rod, so that the device can automatically separate the unqualified products, further improving the assembly efficiency.
