Description

Technical Field

[0001] The utility model relates to an assembly device for a knob switch, in particular to a spring feeding device for the knob switch. Background Art

[0002] With the continuous updating of science and technology, electronic products are updated and iterated rapidly. Whether it is 3C electronic products, communication devices or household appliances and other commonly used electronic products in life, they are often equipped with knob switches. Knob switches are generally used to control the opening and closing of electrical appliances, or to adjust the direction, speed and strength of electrical appliances during operation, such as the speed of electric fans, the cooling strength of air conditioners, the volume of audio, the brightness of lights, and the signal strength of radios, etc., which require the use of various different control switches.

[0003] The knob switch includes a knob, a housing, a gear, a cam and a spring. During the assembly process of the knob switch, the spring needs to be loaded and placed in the housing. During the loading process, the spring is placed horizontally, but needs to be placed vertically in the housing. Therefore, an additional rotating motor is required to rotate the spring, which increases the number of steps and the assembly cost. Utility Model Content

The use of guide plates and other components saves a rotating motor. Compared with the increased objects, the cost of the rotating motor is higher, so the cost can be effectively reduced.

[0007] The utility model is further configured as follows: the guide track includes a first parallel track, a transition track and a second parallel track, the first parallel track and the second parallel track are parallel to the moving direction of the moving block, the height of the first parallel track is higher than the height of the second parallel track, the transition track is between the first parallel track and the second parallel track and connects the first parallel track with the second parallel track.

[0008] By adopting the above technical solution, when the guide end moves from the second parallel track to the first parallel track, the clamping claw member moves from the vertical material discharge position to the horizontal material collection position, and vice versa.

[0009] The utility model is further configured as follows: the feeding mechanism includes a spring vibration plate, a spring feeding track and a feeding tube; the spring vibration plate feeds the spring and transmits it to the spring feeding track; the end of the spring feeding track is connected to the feeding tube; the end of the feeding tube is opposite to the lateral material taking position of the clamping claw; the moving direction of the moving block is parallel to the direction of the feeding tube.

[0011] The utility model is further configured as follows: the clamping jaw member comprises a clamping jaw cylinder, a left clamping block and a right clamping block, the clamping jaw cylinder is arranged on the linkage block, the left clamping block and the right clamping block are arranged on the clamping jaw cylinder and the clamping jaw cylinder drives the left clamping block and the right clamping block to move closer to or away from each other.

[0012] By adopting the above technical solution, when material needs to be taken, the left clamp block and the right clamp block approach each other and extend into the spring, and then the left clamp block and the right clamp block move away from each other, thereby expanding the spring and achieving the effect of clamping the spring.

At this time, the driver 2 drives the moving block 3 to move, and then drives the linkage rod 4 to move, so that the guide end 61 of the main rotating block 6 moves along the guide track 50, so that the main rotating block 6 rotates, drives the linkage rod 4 to rotate, and makes the linkage block 7 rotate, thereby driving the clamping claw member 8 to rotate. During the horizontal movement of the clamping claw member 8, it can rotate at the same time. When the clamping claw member 8 is in the horizontal material picking position, the spring can be clamped. At this time, the spring is placed horizontally, and then the driver 2 drives the moving block 3 to move, so that the clamping claw member 8 rotates while moving horizontally. When the clamping claw member 8 moves to the vertical material discharge position, the spring is placed vertically, and then the spring can be placed in the corresponding workpiece. The use of components such as the guide plate 5 saves a rotating motor. Compared with the increased objects, the cost of the rotating motor is higher, so the cost can be effectively reduced.

[0020] The guide track 50 includes a first parallel track 51, a transition track 53 and a second parallel track 52. The first parallel track 51 and the second parallel track 52 are parallel to the moving direction of the moving block 3.

At this time, the driver 2 drives the moving block 3 to move, thereby driving the linkage rod 4 to move, and the guide end 61 of the main rotating block 6 moves along the guide track 50, so that the guide end 61 moves from the second parallel track 52 to the first parallel track 51, so that the main rotating block 6 rotates, driving the linkage rod 4 to rotate, and the linkage block 7 rotates, thereby driving the clamping claw 8 to rotate, and the clamping claw 8 moves from the vertical discharge position to the horizontal material picking position. At this time, the left clamping block 82 and the right clamping block 83 approach each other and extend into the spring, and then the left clamping block 82 and the right clamping block 83 move away from each other, thereby stretching the spring to achieve the effect of clamping the spring, and then the driver 2 drives the moving block 3 to move in the opposite direction, and the clamping member moves from the horizontal material picking position to the vertical discharge position, and finally the spring can be placed vertically in the corresponding workpiece.
