Description

Technical Field

[0001] The invention relates to the technical field of vehicle lamp manufacturing, in particular to a lampshade gate rotary shearing device. Background Art

[0002] After the lampshade of the car headlight is ejected from the injection molding machine, the columnar gate needs to be sheared. The diameter of the columnar gate is relatively large, about 7 mm. In the existing technology, a pair of scissors is manually held, the blade of the scissors is placed at the root of the columnar gate, and both hands are used to cut it at the same time. On the one hand, manual operation requires training before it can be put into production quickly. The manual operation rhythm is slow, and it is very easy to scratch the lampshade due to misoperation. Shearing requires a lot of force, which will cause fatigue to the personnel. On the other hand, the gate is not actually cut off, but broken off, and the fracture is not delicate. The broken gate will also scratch the lampshade, and the gate left on the lampshade after cutting will also affect the subsequent steps. Summary of the Invention

[0003] In order to solve the technical problems in the prior art that the manual component of lampshade gate shearing is too high and the sheared gate will remain on the lampshade and affect subsequent work steps, the present application proposes a lampshade gate rotary shearing device to solve the above technical problems.

[0004] The technical solution adopted by the present invention to solve its technical problem is:

[0005] The present invention provides a lampshade gate rotary shearing device, comprising: a frame; a shearing module, the shearing module comprising a rotating shaft and an air scissors, the rotating shaft being rotatably configured on the frame, the rotating shaft being vertically arranged, and the air scissors being configured at the bottom end; a rotary positioning module, the rotary positioning module comprising an induction disk and a triggering member, the induction disk being fixed on the frame, and a plurality of position sensors arranged in a ring shape being configured on the disk, the triggering member being fixed on the rotating shaft and triggering corresponding position sensors as the rotating shaft rotates to determine the angular position of the air scissors; a clamping module, the clamping module comprising a clamping claw fixed on the scissor arm of the air scissors, the clamping claw being configured on the inner side opposite to the scissor arm, and being located between the rotation point and the cutting edge of the scissor arm, so as to clamp the lampshade gate before the cutting edge of the scissor arm reaches the lampshade gate.

[0006] Furthermore, the shearing module further includes a power input assembly, and the power input assembly includes a motor arranged on the frame, and the output shaft of the motor drives the rotating shaft to rotate through a synchronous belt.

[0007] Furthermore, the output shaft of the motor and the rotating shaft are both equipped with pulleys, and the synchronous belt is fitted on the pulleys.

[0008] Furthermore, the frame includes a first connector for assembling the motor and a second connector for assembling the shearing module, and an adjustment component is configured at the connection between the first connector and the second connector. The adjustment component includes a nut block slidably configured on the first connector and an adjustment bolt engaged with the nut block, and one end of the adjustment bolt abuts against the second connector to adjust the connection position of the first connector and the second connector.

[0009] Furthermore, a connecting block is fixed on the induction disc, and the connecting block is fixed on the frame.

[0010] Furthermore, the clamping claw is screwed onto the scissor arm, and one end of the clamping claw away from the scissor arm is formed into a clamping portion adapted to the shape of the lampshade gate.

[0011] Based on the above technical solution, the technical effects that can be achieved by the present invention are:

[0012] The lampshade gate rotary shearing device of the present invention is that the lampshade is first placed on the air scissors of the shearing module, and the air scissors perform automatic shearing. Specifically, when the scissor arms of the air scissors are closed together, the clamping claws on the scissor arms will clamp the lampshade gate before the cutting edge of the scissor arms for pre-positioning to ensure that the cutting edge can reach the accurate position. Due to the large diameter of the lampshade gate, the lampshade gate needs to be sheared multiple times, and the gate needs to be slowly cut off from the lampshade to avoid the gate breaking and resulting in a rough fracture and to prevent the gate from splashing and scratching the lampshade. Therefore, the lampshade gate rotary shearing device of the present invention is that the cutting edge of the air scissors is sheared multiple times after rotating along the circumference of the gate, and the rotary positioning module can trigger the position sensor through the trigger part on the rotating shaft. After the position sensor senses the trigger part, it can transmit a signal to the host computer, and the host computer can accurately know the angle of the cutting edge relative to the circumference of the gate, control the cutting edge of the air scissors to perform one shear, and then the host computer controls the rotation of the rotating shaft, and the trigger part triggers the second The position sensor at the angle position can transmit a signal to the host computer after sensing the trigger part. The host computer controls the blade of the air scissors to perform a second shearing until the gate is gently removed from the lampshade according to the established procedure. It should be noted that after the air scissors complete the shearing at the last angle, the scissor arm of the air scissors remains in a closed state, thereby ensuring that the gate is clamped by the claws on the scissor arm, so as to avoid the gate splashing or falling onto the lampshade and affecting subsequent work steps. The clamping module is configured on the scissor arm of the air scissors, and the clamping module will not interfere with the rotation step of the air scissors. If the clamping module blocks the rotation path of the scissor arm, the air scissors will need to remove the clamping module first for each rotation step. In summary, the lampshade gate rotary shearing device of the present invention maximizes the speed of automated shearing while realizing automated shearing, and solves the technical problem that the sheared gate will remain on the lampshade and affect subsequent work steps.
