[0037] The upper side of the hook body 123 is vertically provided with a receiving groove 1231. One end of the receiving groove 1231 close to the support shaft 122 is vertically slidably connected to a pressing block 1232 projecting from the upper side of the receiving groove 1231. The receiving groove 1231 There is also a limit rod 1233 rotatably connected to the accommodating groove 1231 in the middle. Under normal conditions, both ends of the limit rod 1233 can be located in the accommodating groove 1231, and one end of the limit rod 1233 is located on the lower side of the pressure block 1232. , Pressing the pressing block 1232 to a horizontal state, the pressing block 1232 can drive the end of the limiting rod 1233 located at the pressing block 1232 to rotate downward, so that the end of the limiting rod 1233 away from the pressing block 1232 rotates upwards until it protrudes from the receiving groove 1231 The upper side of the hook body 123 further restricts the workpiece on the upper side of the hook body 123 to prevent the workpiece from slipping off the end of the hook body 123 away from the support shaft 122. A return spring 1234 is vertically fixed in the accommodating groove 1231 at a position corresponding to the lower side of the pressure block 1232. The upper end of the return spring 1234 is fixed to the lower side of the limit rod 1233 at the position of the pressure block 1232. When falling, the upper side of the pressure block 1232 loses force, and the return spring 1234 can push the limit rod 1233 on the lower side of the pressure block 1232 to rotate upward, thereby pushing the pressure block 1232 to rise to complete the reset.
[0038] The loading station 2 includes a loading conveyor belt 21 that is horizontally arranged and one end is located on the lower side of the conveying track 11. The feeding conveyor belt 21 can convey the workpiece in a direction close to the conveying track 11. When working, the operator can directly hang the workpieces conveyed from the loading conveyor belt 21 on the hook body 123 of the hoisting frame 12 to complete the loading of the workpieces.
[0039] Reference figure 1 with Figure 4 The spray cleaning station 3 includes a spray cleaning box 31 arranged at one end of the conveying track 11. The spray cleaning box 31 is provided with a first through slot 311 that can facilitate the insertion of the lower end of the lifting frame 12 into the spray cleaning box 31 on the upper side. On both sides of the conveying trajectory of the corresponding hoisting frame 12 are provided with a number of spray guns 32 capable of spraying air to the workpiece, and the outer side of the blowout box 31 is fixed with a gas tank 33 capable of conveying gas to the spray gun 32, and the blowout box 31 Corresponding to the position of the lower side of the hoisting frame 12 along the movement track of the hoisting frame 12 is fixedly connected with a blanking trough 34, the lower side of the blanking trough 34 has several dust outlets, and the lower side of each dust outlet is connected with bolts The cloth dust bag 35, the blower box 31 corresponding to the position on the lower side of each dust collection belt are fixedly connected with the exhaust fan 36, the side door 37 is provided on the side of the blower box 31 corresponding to the position of each dust bag 35, open The side door 37 can facilitate taking out the dust collecting bags 35, and both ends of the blowout box 31 are also fixedly connected to the first flexible dust curtain 38. During work, when the workpiece moves with the hoisting frame 12 into the cleaning box 31, the high-pressure air pump can spray air on the workpiece hanging on the hoisting frame 12, and since the workpiece is transferred to the cleaning station 3, the support shaft 122 can drive the original workpiece. The position is rotated, so that the workpiece can be cleaned in all directions. At the same time, the exhaust fan 36 works to draw the dust in the blowout box 31 down to the dust bag 35 under the blanking trough 34, thereby completing the passage The dust collecting bag 35 completes the dust collection. After finishing the work, open the side door 37 and take out the dust collecting belt and dump it.
[0040] Reference figure 1 with Figure 5 The spraying station 4 includes a spray paint box 41 arranged on one side of the conveying track 11. The upper side of the spray paint box 41 is provided with a second through slot 411 that can facilitate the insertion of the lower end of the hoisting frame 12 into the paint spray box 41, and the paint spray box 41 corresponds to hoisting A number of paint spray guns 42 capable of spraying paint on the workpiece are provided on both sides of the conveying track of the rack 12. The outside of the paint spray box 41 is also fixed with a liquid storage tank 43 capable of delivering paint to the paint spray gun 42.
