Description

Technical Field

[0001] This utility model relates to the field of key processing technology, specifically to an internal tooth key reading machine. Background Technology

[0002] With the increasing popularity of cars, our lives have become more and more convenient, and car keys are an important component of cars;

[0003] During the production of car lock cylinders, the key needs to be processed with corresponding tooth shapes according to the key number. Currently, when processing the key, a barcode corresponding to the key tooth shape is printed at the same time. The key and the barcode are sent to the next production process together. During the circulation process, the barcode may become confused.

[0004] To address this issue and eliminate the need for barcode paper, an internal tooth key reader is proposed to solve the aforementioned problems. Utility Model Content

The detection fixture has a through hole inside, and an internal toothed key is inserted into the through hole. The front end of the detection fixture is provided with evenly arranged left-facing detection pieces, and the rear end of the detection fixture is provided with evenly arranged right-facing detection pieces. Detection piece springs are fixed to the side walls of both the evenly arranged left-facing and right-facing detection pieces. The other end of the detection piece springs is fixedly connected to the inner wall of the through hole.

[0009] The detection fixture has through-beam sensors fixed on both its left and right sides.

[0010] Preferably, the front side of the base plate is fixed with symmetrical hinges, and the protective cover is rotatably connected to the base plate via the hinges.

[0011] Preferably, the sides of the uniformly arranged left-facing detection pieces and the uniformly arranged right-facing detection pieces that are close to each other are in contact with the internal tooth key.

[0012] Preferably, the side wall of the protective cover has a key insertion hole at the upper end of the testing fixture.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This application eliminates the need to print barcodes corresponding to the key teeth during key processing, effectively preventing barcode confusion during the circulation process and making key processing more convenient.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] Example:

[0027] Please see Figure 1-8 This utility model provides a technical solution:

[0028] The internal tooth key reader includes a base plate 1, a first support plate 2 fixed to the rear end of the upper side of the base plate 1, a second support plate 3 fixed to the left end of the upper side of the base plate 1, and a protective cover 4 provided at the upper end of the base plate 1.

[0029] A reference block 5 is fixed to the right side of the second support plate 3, a light source 6 is fixed to the rear side of the reference block 5, and an imaging device 7 is fixed to the front side of the first support plate 2.

[0030] A detection fixture 8 is fixed to the front side of the first support plate 2 at the right end of the light source 6. The detection fixture 8 has a through hole inside, and an internal tooth key 9 is inserted into the through hole. The front end of the detection fixture 8 is provided with evenly arranged left-facing detection pieces 10, and the rear end of the detection fixture 8 is provided with evenly arranged right-facing detection pieces 11. Detection piece springs 12 are fixed to the side walls of both the evenly arranged left-facing detection pieces 10 and the evenly arranged right-facing detection pieces 11. The other end of the detection piece spring 12 is fixedly connected to the inner wall of the through hole. The detection piece spring 12 drives the left-facing detection pieces 10 and the right-facing detection pieces 11 to move, thereby detecting the tooth shape of the internal tooth key 9.

[0031] Both the left and right sides of the detection fixture 8 are fixed with through-beam sensors 13. The through-beam sensor 13 usually consists of a transmitter and a receiver. When the key is inserted into the tooth reader, the sensor can detect the change point of the key tooth shape. Whenever the tooth or groove on the key passes between the sensors, it will temporarily block the light and generate a signal change, thereby determining the specific position of each tooth. Through multiple through-beam sensors 13, the depth information of the key teeth can be measured. The sensor can judge the depth of the teeth according to the degree of light being blocked, and thus obtain detailed tooth shape data.

[0032] Symmetrical hinges are fixed to the front side of the base plate 1, and the protective cover 4 is rotatably connected to the base plate 1 via the hinges.

[0033] The sides of the evenly arranged left-facing detection pieces 10 and the evenly arranged right-facing detection pieces 11 that are close to each other are in contact with the internal tooth key 9.

[0034] The protective cover 4 has a key insertion hole on the side wall at the upper end of the testing fixture 8.

[0035] Working principle: The internal tooth key 9 is inserted into the detection fixture 8. Under the action of the detection spring 12, the left detection piece 10 and the right detection piece 11 contact the internal tooth key 9. The internal tooth key 9 reads the status of the detection pieces. The height of different tooth-shaped detection pieces is different. After the host computer detects the key insertion through the through-beam sensor 13, it starts the imaging device 7 to detect the distance between each left detection piece 10 and right detection piece 11 and the reference block 5. Based on the height dimension between the left detection piece 10 and right detection piece 11 and the reference block 5, the corresponding key number is found from the database and the data can be sent to the film setter, printer, or laser engraving machine, etc.
