Description

Technical Field

[0001] This utility model relates to the field of watch strap spring bar manufacturing technology, and in particular to a spring bar positioning device. Background Technology

[0002] Spring bars are flexible shaft components used to hinge the watch strap to the watch case. Traditionally, spring bars have grooves on the pins, which are then moved using a special tool. Now, spring bars with a lever have appeared on the market. These levers have protrusions on the pins, which can be moved by hand to press the pins, allowing for manual assembly and disassembly of the watch strap. Because the steel tube of the lever spring bar has notches on its side wall, the steel tube needs to be oriented and fixed before assembly. Current spring bar assembly machines use manual operation for steel tube orientation, resulting in low assembly efficiency and poor product consistency. Therefore, spring bar assembly machines have emerged on the market.

[0003] For example, patent CN115582693A discloses a spring ear assembly machine with directional steel pipe conveying, including a rotary feeding mechanism and a steel pipe feeding device. The rotary feeding mechanism is equipped with multiple steel pipe carriers evenly distributed along the circumference, which are used to position and fix the steel pipes. The steel pipe feeding device is correspondingly installed on the outside of the rotary feeding mechanism. The steel pipe feeding device includes a first support, a feeding mechanism, a driving mechanism, a clamping and positioning mechanism, and a rotational orientation mechanism. The feeding mechanism is installed on the first support and is used to sequentially convey steel pipes with notches facing the same direction to the steel pipe carriers. The driving mechanism is installed on the top of the first support and is used to provide lifting power. The clamping and positioning mechanism is installed on the output end of the driving mechanism and is used to clamp and position the steel pipes located on the steel pipe carriers from the left and right. In actual use, the steel pipes rolling down from the feeding track enter the positioning recess for initial positioning. Then, the clamping and positioning mechanism clamps and positions the steel pipes on the positioning recess. Then, the rotational orientation mechanism cooperates with the positioning recess to rotate the steel pipes to a position with the notches facing upwards.

[0004] The problem with the above technology is that the assembly machine uses a positioning recess and a rotating orientation mechanism to position the steel pipe, thereby rotating the steel pipe to a position where the notch faces upwards. When the steel pipe is a defective product with no notch or a notch size that does not conform to the positioning recess, the positioning recess cannot detect the notch position of the steel pipe. Therefore, in actual use, the assembly machine is prone to getting stuck at the steel pipe positioning step. At this time, manual intervention is required to remove the defective product, otherwise it is easy to cause jamming.

[0005] To address this issue, a raw ear positioning device is proposed. Utility Model Content

[0006] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a spring ear positioning device that can accurately locate the notch on the spring ear.

[0007] The technical solution adopted by this utility model to solve the problem is: a raw ear positioning device, including a fixing device, a fixing bracket provided on the top of the fixing device, a top rod that can move vertically provided in the fixing bracket, the top of the top rod that can extend into a fixing groove, a calibration device provided on the side of the fixing device, the calibration device including a clamp that can move laterally, a rotating motor provided at one end of the clamp, the other end of the clamp facing the fixing groove, and a laser detection device provided above the fixing device.

[0008] As a further improvement to the above technical solution, a stop block is provided on the side of the fixed bracket, the stop block is directly opposite the fixing groove, and the fixing groove is located between the stop block and the clamp.

[0009] As a further improvement to the above technical solution, a rotating seat is provided at the bottom of the fixing device.

[0010] As a further improvement to the above technical solution, the fixing device is elastically connected to a limiting seat on the side, the limiting seat is provided with a limiting block, the rotating seat is provided with a plurality of limiting grooves, and the limiting block is inserted into the limiting groove.

[0011] As a further improvement to the above technical solution, the calibration device includes a first movable seat capable of lateral movement, and the clamp is disposed on the first movable seat.

[0012] As a further improvement to the above technical solution, the calibration device includes a second movable seat that can move laterally, and the first movable seat is disposed on the second movable seat.

[0013] The beneficial effects of this utility model are as follows: In use, the fixing groove can receive the spring ear, the clamp can move towards the fixing groove and clamp the steel pipe, the laser detection device is activated and detects the notch on the steel pipe, the rotating motor drives the clamp to rotate, thereby driving the steel pipe to rotate, until the laser detection device detects that the notch on the steel pipe has rotated upward, the rotating motor can stop rotating, the clamp returns to its original position, and at the same time the top rod can move upward and press the steel pipe in the fixing groove. The laser detection device is activated again and detects the mounting hole on the nail head in the notch of the steel pipe, the clamp can move towards the fixing groove and clamp the nail head, the rotating motor drives the clamp to rotate, thereby driving the nail head to rotate, until the laser detection device detects that the mounting hole on the nail head has rotated upward. Compared with the prior art, this positioning device can accurately locate the spring ear and detect defective products, making it more intelligent. Attached Figure Description
