[0022] A wire rod is placed on two wire rod positions of two brackets 11 that are opposite to each other along the front-back direction, and the multiple wire rod positions on each bracket 11 are spaced apart along the left-right direction, so that multiple wire rods can be placed on the placement rack 1 along the left-right direction for batch dipping. After the dipping is completed, the placement rack is mounted by a lifting mechanism, and the four lifting anti-slip blocks 13 limit the lifting structure to prevent it from falling out of the placement structure 111, and the placement rack 1 is transported to the oven for baking. In addition, each installation position can also be used to place the legs 112, so that two placement racks 10 are stacked to place more wire rods and improve production efficiency. In this way, the structure is simple and easy to use.

[0023] Specifically, in this embodiment, refer to Figure 2 , Figure 3 , Figures 5 to 7 Each of the placement structures 111 includes a placement panel 1111 and a plurality of wire rod retaining members 1112. The placement panel 1111 extends in the left-right direction.

Each of the placement panels 1111 is provided with a placement groove 11121 with a notch facing upward and a front and rear groove wall passing through. The wire rod retaining member is formed in the placement groove 11121. The plurality of placement grooves 11121 are distributed at intervals in the left-right direction, and a plurality of wire rods are placed one by one, so that the plurality of wire rods can be separated, so as to facilitate the varnishing and drying of a single wire rod, and avoid damage caused by collision and extrusion between wire rods. The structure is simple and easy to set up.

[0024] It should be noted that the material of the wire rod retaining member 1112 is set to polytetrafluoroethylene, or the groove wall of the placement groove 11121 is coated with a polytetrafluoroethylene film layer, so as to prevent the wire rod from sticking to the placement groove 11121.

[0025] More specifically, in this embodiment, continue to refer to Figure 2 , Figure 3 , Figures 5 to 7 Each of the wire rod retaining members 1112 has a mounting block 11122 protruding from both the front and rear sides, and each of the mounting blocks 11122 has a mounting hole extending in the up-down direction; the placement panel 1111 has a plurality of threaded holes corresponding to the plurality of mounting holes; each of the brackets 11 also includes a plurality of bolts 14, and each of the bolts 14 passes through each of the mounting holes and is screwed into each of the threaded holes. Thus, each of the wire rod retaining members 1112 can be detachably mounted on the placement panel 1111, with a simple structure, convenient operation, and convenient disassembly and replacement.

[0026] It should be noted that the present invention does not limit the number of the mounting holes provided on each mounting block 11122, as long as the wire rod retaining member 1112 can be fixed on the placement panel 1111. In this embodiment, each mounting block 11122 is provided with two mounting holes, and the two mounting holes are spaced apart in the left-right direction, so that the wire rod retaining member 1112 can be more stably and firmly installed on the placement panel 1111.

[0027] In another embodiment, the placement panel 1111 is provided with two connection holes connected in the left-right direction on both the front and rear sides of each of the wire rod retaining members 1112, and each of the bolts 14 is screwed into each of the connection holes and abuts against the front side or the rear side of the wire rod retaining member 1112, so that each of the wire rod retaining members 1112 is fixed to the placement panel 1111 by four bolts 14. In this way, disassembly and assembly are convenient, and maintenance and replacement are easy.

[0028] In this embodiment, each of the placement structures 111 further includes at least four connection blocks 113, and each two of the connection blocks 113 are respectively connected to the front and rear sides of each of the placement panels 1111 near its end, and the upper side of each of the connection blocks 113 is flush with the upper side of the placement panel 1111; each of the installation positions is formed on the upper side of each of the placement panels 1111 near its end and the upper side of the corresponding two connection blocks 113. Thus, the area of ​​the installation position is increased, so that when two placement racks 1 are stacked, the placement rack 1 of the lower layer can stably receive the legs of the placement rack 1 of the upper layer.

[0029] In the present invention, reference is made to Figure 1 The two placing racks 1 are divided into a first placing rack 1a and a second placing rack 1b placed on the upper side of the first placing rack 1a. When the number of wire rods to be produced is small, only the first placing rack 1a can be used. When the number of wire rods to be produced is large, both the first placing rack 1a and the second placing rack 1b can be used.

[0030] In order to prevent the second placement rack 1b from shifting in the horizontal plane due to the lubrication of the insulating paint and tilting away from the installation position, in this embodiment, reference Figures 2 to 4 , the first placement rack 1a also includes at least four limit frames 2, each of which is arranged at each of the installation positions. Thus, the four legs 112 of the second placement rack 1b are inserted into the frame holes of the four limit frames 2 in a one-to-one correspondence, so that when the second placement rack 1b is translated, each of the legs 112 of the second placement rack 1b abuts against the limit frames 2, preventing each of the legs 112 of the second placement rack 1b from being separated from the corresponding installation positions, ensuring that the second placement rack 1b is always stably placed on the first placement rack 1a.

[0031] In order to prevent the legs 112 of the second placement rack 1b from adhering to the limiting frame 2, in this embodiment, an anti-adhesion pad 4 is provided on the upper surface of each placement panel corresponding to each limiting frame 2, and the anti-adhesion pad 4 is made of polytetrafluoroethylene. Each leg 112 is placed on each anti-adhesion pad 4.

[0032] In this embodiment, refer to Figures 5 to 7 The bracket 11 of the second placement rack 1b further includes at least two limit blocks 3, which are installed on the placement panel 1111 and respectively abut against the rightmost and leftmost wire rod retaining members 1112 among the plurality of wire rod retaining members 1112. The two limit blocks 3 are used to limit the plurality of wire rods to prevent the wire rods of the second placement rack 1b from falling off from the corresponding limit grooves.

[0033] Further, in this embodiment, continue to refer to Figures 2 to 4 Each of the limit frames 2 is provided with an opening 21 facing the plurality of wire rods, and the opening 21 is used for the insulating paint to flow out from the frame hole of the limit frame 2, so as to avoid being retained in the limit frame 2, and to facilitate subsequent use. In addition, the material of the limit frame 2 is polytetrafluoroethylene material, which can also prevent the insulating paint from sticking.

[0034] Specifically, in this embodiment, refer to Figures 2 to 4 Each of the anti-sticking pads 4 is provided with a through hole 41 extending in the up and down directions; each of the placement panels 1111 is provided with an outflow hole 11111 corresponding to the through hole 41, and the through hole 41 and the outflow hole 11111 can also allow the insulating paint on the anti-sticking pad 4 to flow out from the limiting frame 2.

[0035] In order to strengthen the structure of each of the brackets 11, each of the brackets 11 also includes at least two connecting members 114 and multiple first supporting members 115. The two connecting members 114 extend in the left-right direction and are spaced apart in the up-down direction. The two ends of each of the connecting members 114 are respectively connected to the two supporting legs 112, and the two ends of each of the first supporting members 115 are connected to the upper side of the connecting member 114 located on the upper side and the lower side of the placement panel 1111, and are inclined in the left-right direction.

[0036] In this embodiment, the first support members 115 are arranged in four, and the inclined directions of two adjacent first support members 115 are staggered, and each of the brackets 11 also includes a second support member 116 extending in the up-down direction and at least two third support members 117, the second support member 116 extending in the up-down direction, and its upper and lower ends are respectively connected to the middle of the lower side of the placement panel 1111 and the middle of the upper side of the connecting member 114 located on the upper side. The upper ends of the two third support members 117 are respectively connected to the left and right ends of the lower side of the placement structure 111, and the lower ends are respectively connected to the middle of the two legs 112, and are respectively close to the upper ends of the two legs 112. The structure of the placement rack 1 is further strengthened to improve the bearing performance.

[0037] In this embodiment, each of the placement panels, each of the connection plates 12, each of the legs 112, and each of the connection members 114 is provided with a reinforcing rib 5. Thus, the strength of each of the connection plates 12, each of the legs 112, and each of the connection members 114 can be strengthened to prevent the connection plates 12, each of the legs 112, and each of the connection members 114 from being deformed.

[0038] It should be noted that the present invention does not limit the length of the four legs 112 of each of the placement racks 1. As long as the end of the wire rod on the second placement rack 1b that extends downward does not contact the wire rod placed on the first placement rack 1a. It is also possible to install multiple wire rod retaining members 1112 so that the placement grooves 11121 on the second placement rack 1b and the placement grooves 11121 on the first placement rack 1a are staggered, which can also prevent the ends of the wire rods on the second placement rack 1b from contacting the wire rods on the first placement rack 1a. This avoids the phenomenon of insulation damage caused by the insulation layers sticking together, thereby ensuring good production quality.

[0039] The method for using the VPI single wire rod batch production device includes: Place the wire rods of the stator wire slots of the generator in the multiple placement slots 11121 of the first placement rack 1a, and then use a rope to put it on the inner side of the lifting anti-slip block 13, and lift the first placement rack 1a into the VPI tank. Place the wire rods of the stator wire slots of the generator in the multiple placement slots 11121 of the second placement rack 1b, and then use a rope to put it on the inner side of the lifting anti-slip block 13, and lift the second placement rack 1b into the VPI tank and place it on the upper side of the first placement rack 1a at the position between the legs 112 and the lifting anti-slip block 13, and dip it together. After the dip and dripping of paint are completed, first use a lifting device to transport the second placement rack 1b out of the VPI tank. Then use a lifting device to transport the first placement rack 1a out of the VPI tank and place it on the trolley of the oven. The second placement rack 1b is hoisted again onto the first placement rack 1a by a lifting device. After a certain period of time of heating in the oven, the wire rod production is completed, and the insulating paint on the bare copper wire at the end of the wire rod is burned off by fire.

[0040] The VPI single wire rod batch production device proposed by the present invention simplifies the process flow and improves work efficiency; it is easy to maintain and simple to replace parts.
