Description

TECHNICAL FIELD

[0001] The application relates to the spring hook production field, in particular to a spring hook detection device. BACKGROUND

[0002] The spring hook is a common hardware product, which is widely used in mountaineering buckles, cord buckles, pet chains, key accessories, special-shaped chains, luggage buckles, connecting hooks, anti-skid chains and the like. The spring hook is mostly in the shape of a gourd, which is formed by a C-shaped long section and a straight short section being hingedly connected into a closed ring by a rivet. The long section and the short section are hingedly connected at one end by the rivet, and the other end of each of the long section and the short section is provided with a recess and a protrusion, so as to be engaged with each other to realize connection. After the spring hook is assembled, the spring hook needs to be detected, which includes checking whether the short section is conveniently opened, whether the short section can be reliably reset under the action of a spring or a torsion spring, and whether the long section and the short section are left-right offset.

[0003] A spring hook detection machine is provided in Patent No. CN 202110286311.9, which includes a hook detection device for pressing the short section of the spring hook and a detection device for detecting the closing condition of the short section of the spring hook, so as to detect the short section recovery closing condition after the hook detection piece is pressed, thereby realizing sorting and screening. The hook detection machine only completes the basic screening, and the waste rate is high, and the long section and the short section are left-right offset in the waste. UTILITY MODEL CONTENT

[0004] The application provides a spring hook detection device, which is used for automatically and comprehensively detecting the assembled spring hook, including checking whether the short section is conveniently opened, whether the short section can be reliably reset under the action of a spring or a torsion spring, and whether the long section and the short section are left-right offset. Thus, the problems existing in the spring hook are comprehensively found, the product quality is ensured, and the waste rate is reduced.

[0006] The offset in the application refers to the left-right offset of the short section of the spring hook and the long section of the spring hook. The main reason why the short section of the spring hook cannot be opened after being pressed or cannot be reset after being opened in the production and assembly process is that the protrusion and the recess of the short section and the long section are not completely engaged, and there is an offset in the length direction of the spring hook.

[0007] Further, the detection driving member is installed on the upper end of the detection support and the lower end of the detection driving member is connected with the detection top pressing rod, the first sensor is installed on the detection support and located above the spring hook to be detected, and the second sensor is connected with the detection support through the driving unit.

[0008] Further, the detection driving member and the driving unit are both formed by a cylinder.

[0009] Further, the first sensor is installed on the detection support through the first hanging plate.

[0010] Further, the driving unit is installed on one side of the detection support, and the second sensor can be extended to the side of the spring hook to be detected under the driving of the driving unit.

[0011] Further, the first sensor and the second sensor are infrared sensors or visual sensors.

[0012] The detection driving member is used to drive the detection top pressing rod to move up and down so as to press the spring hook short section, the first sensor is installed on the detection support and located above the clamping device, and is used to detect whether the spring hook can be pressed open and whether it can be reset, the driving unit can drive the second sensor to move linearly and reciprocally, so that when the second sensor is in the detection state, the driving unit extends the second sensor to one side of the rotating disc clamping device, so that the second sensor is located on one side of the spring hook and is used to detect whether the short section and the long section are left-right deviated, and when the second sensor is in the non-detection state, the driving unit retracts the second sensor to the outside of the rotating disc to avoid interfering with the rotation of the rotating disc.

[0013] The spring hook detection device provided by the embodiment of the application can achieve the following beneficial effects:

[0014] The application can realize full-automatic and comprehensive detection of the spring hook, detect the deviation of the spring hook and the opening and resetting of the short section through the detection device, so as to facilitate subsequent targeted correction, improve production efficiency, guarantee product quality and reduce the waste rate.
