When the second slider 51 passes through the second section 501, the workpiece spraying operation is performed, after the workpiece spraying is completed, the second slider 51 reaches a critical position between the third section 502 and the second section 501, and when the second slider 51 passes through the critical position, the pressure applied to the second slider 51 is gradually reduced, then the distance between the first pressing portion 510 and the second pressing portion 511 is gradually increased under the effect of the resilience force of the second elastic member, so that the extrusion force on the first support rod 52 is gradually reduced, after the second slider 51 completely enters the third section 502, the extrusion forces on the first support rod 52 by the first pressing portion 510 and the second pressing portion 511 completely disappear, at this time, correspondingly, after the second support rod 322 breaks away from the conveying unit 2, under the effect of the resilience force of the first elastic member, the deformation strip 312 returns to the linear state first, and in the process that the deformation strip 312 returns to the linear state, the first support rod 52 is driven to gradually extend from the first pressing portion 510 and the second support rod 511 to the initial position, and then in the process that the deformation strip 312 returns to the initial position from the third section 502 to the third section 501 again, and then in the process that the second pressing portion 51 returns to the initial position 500.
To sum up, when the conveying unit 2 drives the workpiece to move in the first direction, the conveying unit 2 generates a thrust force on the second stay bar 322, the second stay bar 322 drives the third slider 321 to slide in the third sliding groove 320, the third slider 321 drives the deformation bar 312 to move synchronously, the deformation bar 312 drives the first slider 311 to move in the first sliding groove 310, so that the elasticity of the first elastic member is increased, the movement of the deformation bar 312 drives the first stay bar 52 to move synchronously, the first stay bar 52 drives the second slider 51 to move in the second sliding groove 50, the workpiece extrudes the probe 4 during moving, so that the probe 4 moves in the second direction, the probe 4 extrudes the deformation bar 312, and the deformed deformation bar 312 extrudes the first stay bar 52, the first support rod 52 retracts into the second slide block 51, the second slide block 51 gradually enters the second section 501 from the first section 500 along with the gradual movement of the second slide block 51 in the second sliding groove 50, the distance between the first pressing part 510 and the second pressing part 511 is shortened, the extrusion force on the first support rod 52 is gradually increased, the elastic force of the second elastic part is increased, after the second slide block 51 completely enters the second section 501, the first support rod 52 can be clamped by the first pressing part 510 and the second pressing part 511, the deformed structure of the deformation strip 312 is fixed, along with the continuous movement of the conveying unit 2, the deformed deformation strip 312 can extrude the spray gun 10, so that the spray gun 10 moves in the second direction to keep the distance between the spray gun and the sprayed surface of the workpiece.
After the spraying operation is finished, the conveying unit 2 will gradually take the workpiece to leave from the second interval 111, the second stay bar 322 will gradually move from the straight line part in the third sliding groove 320 to the curved part, the second stay bar 322 will make a circumferential motion along the circle center of the curved part, and it will gradually get rid of the conveying unit 2, in this process, the second slider 51 will gradually enter the third section 502 from the second section 501, the squeezing action of the first pressing part 510 and the second pressing part 511 will gradually disappear, under the effect of the resilience force of the second elastic part, the squeezing action of the two on the first stay bar 52 will gradually lose, after the deformed deformation bar 312 loses the positioning, under the effect of the resilience force of the first elastic part, the linear structure will be restored first, and then the same second slider 51 will be driven back to the initial position in the second sliding groove 50, and then the spraying operation on the next workpiece can be started.
Referring to fig. 4, further, a third stay 100 is hinged at the tail of the spray gun 10, three rollers 101 are arranged at one side of the third stay 100 close to the deformation strip 312, two rollers are arranged on the third stay 100 in parallel along a first direction, the other roller is arranged at the tail of the spray gun 10, the deformation strip 312 is arranged between the two rollers 101 and the other roller 101, thereby forming a push-pull action on the spray gun 10 to maintain the distance between the head of the spray gun 10 and the surface to be coated of the workpiece, the head of the spray gun 10 is hinged with the rod part of the spray gun 10, the head of the spray gun 10 can swing along the hinge point in the first direction, two inelastic pull ropes 102 are symmetrically connected between the third stay 100 and the head of the spray gun 10 by taking the rod part of the spray gun 10 as a symmetry axis, the third stay bar 100, the head of the spray gun 10 and the two pull ropes 102 can form a structure similar to a parallelogram, and the third stay bar 100 and the head of the spray gun 10 can swing, so that when the deformed strip 312 passes through three rollers 101, the two rollers 101 on the third stay bar 100 can be extruded, the third stay bar 100 can swing after being stressed, the third stay bar 100 can be parallel to the deformed strip 312 after being deformed, the head of the spray gun 10 can swing along with the third stay bar 100 under the driving of the pull ropes 102, the swinging direction and the swinging amplitude can be consistent, the nozzle at the head of the spray gun 10 can basically dead against the sprayed surface of a workpiece, and the spraying effect of the workpiece is improved.
