[0030] With reference to Figures 1 to 6 The coating system of the present application is embodied as follows:

[0031] A coating system comprises a coating furnace 300, a workpiece rack 200, a feeding and discharging track 100 and a material moving device 400.

[0032] The feeding and discharging track 100 extends along a first direction. The material moving device 400 is slidably connected with the feeding and discharging track 100 along the first direction. The coating furnace 300 is arranged on one side of the feeding and discharging track 100 along a second direction.

[0033] The workpiece rack 200 has a coating connection end 210 and a material moving connection end 220. The material moving device 400 has a material moving connection part 441 which can extend along the second direction and is detachably connected with the material moving connection end 220. The coating furnace 300 has a coating connection part which is detachably connected with the coating connection end 210.

[0034] In actual use, when the material moving connection end 220 is connected with the material moving connection part 441, the workpiece rack 200 can move along the feeding and discharging track 100 along the first direction together with the material moving device 400.

[0035] When the workpiece rack 200 is aligned with the coating furnace 300, the material moving connection part 441 can extend to send the workpiece rack 200 into the coating furnace 300. At this time, the workpiece rack 200 can be connected with the coating furnace 300 through the coating connection part and the coating connection end 210, and the material moving connection part 441 is disconnected with the material moving connection end 220 and retracted from the coating furnace 300, so that the workpiece rack 200 is transferred from the material moving device 400 to the coating furnace 300, realizing the feeding operation of the workpiece rack 200.

[0036] When the workpiece rack 200 needs to be discharged, the material moving connection part 441 extends into the coating furnace 300 and is connected with the material moving connection end 220, and the coating connection part is disconnected with the coating connection end 210, so that the workpiece rack 200 can be transferred from the coating furnace 300 to the material moving device 400, and the material moving connection part 441 drives the workpiece rack 200 to move out of the coating furnace 300, realizing the discharging operation of the workpiece rack 200.

[0037] In the embodiment, the first direction is the left-right direction, and the second direction is the front-back direction. The first direction and the second direction are perpendicular to each other, and the left-right movement of the material moving device 400, the front-back extension of the material moving connecting part 441, and the front-back movement of the workpiece frame 200 do not easily affect each other.

[0038] To avoid the long waiting time of the plating furnace 300 caused by the loading and unloading of the material on the workpiece frame 200, in the embodiment, the number of the material moving device 400 and the workpiece frame 200 is two. Two workpiece frames 200 can alternately enter the plating furnace 300 for plating processing. When one of the workpiece frames 200 is processed in the plating furnace 300, the other workpiece frame 200 can be used to load and unload the material outside the plating furnace 300, greatly reducing the waiting time and improving the work efficiency. In other embodiments, the number of the workpiece frame 200 can be more than three. The number of the workpiece frame 200 can be set according to the plating processing cycle time and the loading and unloading time of the material on the workpiece frame 200.

[0039] When the number of the workpiece frame 200 is more than one, the number of the material moving device 400 is at least two. At least two material moving devices 400 can respectively move two different workpiece frames 200, so as to realize the rapid replacement of the workpiece frame 200 in the plating furnace 300.

[0040] To realize the rapid loading and unloading of the workpiece frame 200 in the plating furnace 300, the loading and unloading track 100 has a material moving station, a temporary storage station, and a loading and unloading station. The material moving station is aligned with the plating furnace 300 in the front-back direction, and the temporary storage station and the loading and unloading station are respectively arranged on the left and right sides of the material moving station.

[0041] Two material moving devices 400 respectively replace the workpiece frame 200 in the plating furnace 300 through the material moving station and the temporary storage station. Specifically, two material moving devices 400 arranged left and right are respectively a material moving left device 410 and a material moving right device 420.

[0042] When the material moving left device 410 is provided with a workpiece frame 200 loaded with raw material, the material moving left device 410 and the material moving right device 420 respectively move to the temporary storage station and the material moving station. The material moving right device 420 takes out the workpiece frame 200 loaded with cooked material in the plating furnace 300 and moves to the right to the loading and unloading station to unload the cooked material and load the raw material. When the material moving right device 420 moves from the material moving station to the right to the loading and unloading station, the material moving left device 410 moves from the temporary storage station to the right to the material moving station, and sends the workpiece frame 200 on it into the plating furnace 300.

[0043] When the material moving right device 420 is provided with the workpiece frame 200 carrying raw material, the material moving left device 410 and the material moving right device 420 move to the material moving station and the loading and unloading station respectively. The material moving left device 410 takes out the workpiece frame 200 carrying raw material in the coating furnace 300 and moves to the left to the temporary storage station to wait. When the material moving left device 410 moves to the left from the material moving station to the temporary storage station, the material moving right device 420 moves to the left from the loading and unloading station to the material moving station and sends the workpiece frame 200 thereon into the coating furnace 300. Then, the material moving left device 410 and the material moving right device 420 move to the loading and unloading station together and perform loading and unloading operation on the workpiece frame 200 on the material moving left device 410.

[0044] In some other embodiments, the loading and unloading station is provided on both sides of the material moving station, and the material moving left device 410 and the material moving right device 420 can directly move to the corresponding loading and unloading station to perform loading and unloading of material after taking out the workpiece frame 200 from the coating furnace 300. When the loading and unloading station is provided on both sides, the temporary storage station is not required, but the requirement for the site and the unloading and mounting cycle time of the material is higher.

[0045] In some embodiments, the material moving device 400 moves along the loading and unloading track 100 left and right by manual pushing. In order to reduce the labor intensity of manual operation and enable the material moving device 400 to move along the loading and unloading track 100 left and right quickly and accurately, in the present embodiment, the loading and unloading track 100 is provided with a loading and unloading driving member for driving the material moving device 400 to move in the first direction. The loading and unloading driving member has a loading and unloading driving end for driving connection with the material moving device 400 and enabling the material moving device 400 to move left and right relative to the loading and unloading track 100.

[0046] For the case that the number of the material moving device 400 is multiple, the loading and unloading driving member preferably adopts a gear and rack structure. The loading and unloading driving member includes a driving gear, a driving rack and a loading and unloading driving unit. The driving rack extends along the left and right directions and is fixedly arranged on the loading and unloading track 100. The number of the driving gears is consistent with the number of the material moving device 400. The driving gears are correspondingly arranged on the material moving device 400 and mesh with the driving rack. The loading and unloading driving unit is drivingly connected with the driving gear, and the loading and unloading driving unit can adopt a rotary driving element such as a servo motor, a stepping motor or a pneumatic motor.

[0047] In the embodiment, the plating connection end 210 and the material moving connection end 220 are arranged at the upper end of the workpiece rack 200. The plating connection part is arranged at the top of the furnace cavity of the plating furnace 300. In order to avoid hindering the opening and closing of the furnace door 310 of the plating furnace 300, the height of the feeding and discharging track 100 is preferably higher than the top of the plating furnace 300. The material moving device 400 is arranged at the lower side of the feeding and discharging track 100.

[0051] In the embodiment, the material moving driving member 450 adopts a chain wheel and chain transmission structure. The chain wheel is driven by a motor to move the chain arranged in front and back, so as to realize the front-rear movement of the material moving rack body 440 relative to the sliding rack body 430.

[0052] The sliding rack body 430 and the material moving rack body 440 are both rectangular frame structures. The left and right sides of the sliding rack body 430 are both provided with first supporting strips 431 extending in the front-rear direction. The left and right ends of the material moving rack body 440 are both rotatably provided with rollers rollingly abutting against the supporting strips.

[0053] The workpiece rack 200 is heavy due to the weight of the materials thereon. In order to avoid the cantilever structure being unstable when the material moving rack 440 extends relative to the sliding rack 430, in a further embodiment, two second supporting strips 320 corresponding to the two first supporting strips 431 are arranged in the coating furnace 300. The cross-sectional shape of the second supporting strips 320 is consistent with that of the first supporting strips 431. The two second supporting strips 320 are arranged left and right, and the distance between the two second supporting strips 320 is consistent with the distance between the two first supporting strips 431. When the material moving driving member 450 drives the material moving rack 440 to slide forward relative to the sliding rack 430, the rollers of the material moving rack 440 can roll from the first supporting strips 431 to the second supporting strips 320.
