Description

[0002] At present, bolts need to be processed after production, which includes coating molybdenum disulfide on the threads of the bolts to prevent the threads from rusting and seizing. Coating molybdenum disulfide can also make the bolts have excellent high and low temperature resistance and reduce friction during nut installation.

[0003] Most of the tooling lines for coating molybdenum disulfide are automated equipment. Current automated equipment mostly uses the same type of transfer pallet before and after the bolts are coated with molybdenum disulfide. This design leads to poor specialization. For example, before spraying, the bolts have to travel a long distance, so it is necessary to ensure a good fixing effect on the bolts to prevent them from falling during transportation. After spraying, they need to be left alone for a few minutes to ensure that the coating is dry.

[0004] Therefore, how to improve the transfer effect of the transfer device, ensure the stability of the bolt transfer before spraying or ensure that the bolt has a good static environment after spraying is a problem we need to solve. Summary of the invention

[0035] like Figures 1 to 6 As shown, a bolt transfer device includes a feeding device 1 and a unloading device 2 arranged on one side of a robot arm 3; the feeding device 1 includes a plurality of placement racks 120, and the top and middle parts of the placement racks 120 are respectively provided with troughs for connecting bolts, and the connecting line of the top trough and the middle trough is inclined to the gravity direction line, and the bottom of the placement rack 120 is provided with a supporting bottom plate 124 for supporting the bolts; the unloading device 2 includes a plurality of unloading bodies 221, and the unloading bodies 221 are provided with hexagonal troughs for matching with the bolt heads.

[0036] The transfer device of the present application includes a feeding device and a unloading device. The placement frame of the feeding device realizes the placement and fixation of the bolts before spraying through the joint action of the top and middle trough bodies and the bottom supporting base plate. When placing the bolts, the supporting base plate supports the bottom of the bolts, and the top and middle trough bodies limit the middle and top of the bolts to ensure the stability of the bolts after placement. The connection and gravity direction line of the top trough body and the middle trough body are set to be inclined to further increase the stability of the bolts after placement and ensure the stability of the bolts during transportation before spraying. A hexagonal trough body is set in the unloading body of the unloading device to match the bolt head. The head of the bolt after spraying is installed in the hexagonal trough body to prevent the thread at the screw rod from contacting the fixing part, so that the bolt has a good static environment.

[0037] The present application is described below by a specific embodiment. Figure 2 and Figure 3As shown, the placement rack 120 includes a connecting main board 121, the top of the connecting main board 121 is bent to form a placement top plate 122, and the placement top plate 122 is arranged with a plurality of placement slots 1221 along its length direction; the bottom of the connecting main board 121 is bent to the right to form a connecting bottom plate 123, and the connecting bottom plate 123 is used to connect with the mobile rack 110. Specifically, the placement rack 120 can be fixed on the mobile rack 110 by screws penetrating the connecting bottom plate 123. The connecting bottom plate 123 is bent in a U-shape to form a supporting bottom plate 124, and the supporting bottom plate 124 is bent upward to form a limiting plate 125, and the limiting plate 125 is arranged with a plurality of limiting slots 1251 along its length direction, and the number of the limiting slots 1251 is the same as the number of the placement slots 1221.

[0038] like Figure 3 As shown, when placing the bolt, the operator places the end of the screw portion of the bolt on the supporting bottom plate 124, tilts the bolt, and engages the screw portion and the head of the bolt through the limiting groove 1251 on the limiting plate 125 and the placement groove 1221 on the placement top plate 122 to ensure the stability of the bolt after placement.

[0039] In a further embodiment, the top groove body (placement groove 1221) of the placement rack 120 is in the shape of a half regular hexagon, which is designed to fit the hexagonal cross section of the bolt head to ensure the stability of the bolt head. The middle groove body (limiting groove 1251) of the placement rack 120 is in the shape of a U-shape to fit the screw rod.

[0040] Furthermore, the limiting plate 125 is located on a side close to the connecting bottom plate 123 . This design not only saves materials but also does not hinder the robot arm 3 from grasping the screw.

[0041] In a further embodiment, the connection between the main board 121 and the bottom board 123 is provided with a plurality of reinforcing ribs 126. Since the length of the main board 121 is relatively long and a large number of bolts are placed, the overall strength of the placement rack 120 is ensured by the plurality of reinforcing ribs 126.

[0042] In one embodiment, Figure 5 and Figure 6 As shown, the feeding device 1 also includes an AGV trolley 130 and a limiting frame 140. The top of the AGV trolley 130 is connected to a support plate 131 in a detachable manner, and the bottom of the mobile frame 110 is detachably connected to the support plate 131. Specifically, when the mobile frame 110 needs to be moved, the AGV trolley 130 moves to the bottom of the mobile frame 110, lifts the support plate 131, and the support plate 131 lifts the mobile frame 110, which can drive the mobile frame 110 to move. After moving into place, the support plate 131 can be lowered to release the connection between the support plate 131 and the mobile frame 110.

[0043] A plurality of supporting feet are provided at the bottom of the mobile frame 110, and each supporting foot is provided with a caster. The mobile frame 110 can be moved by the casters, and the casters can be locked for locking when it does not need to be moved.

[0044] The limiting frame 140 includes a first side baffle 141 and a second side baffle 142 which are perpendicular to each other. A mounting plate 143 for connecting to the platform is connected to the bottom of the first side baffle 141 or the second side baffle 142. A limiting space for limiting the moving frame 110 is formed between the first side baffle 141 and the second side baffle 142. The AGV trolley 130 drives the limiting frame 140 to move into the limiting space. The two side walls of the moving frame 110 contact the first side baffle 141 and the second side baffle 142 for limiting. A sensor is also provided in the limiting frame 140. The sensor is connected to the AGV trolley 130 by signal. When the AGV trolley 130 drives the moving frame 110 to move to the limiting space, the AGV trolley 130 releases the connection with the moving frame 110.

[0045] like Figure 2 and Figure 4 As shown, the unloading device 2 has a box frame, and a moving mechanism is provided inside the box frame. The moving mechanism can be a lead screw mechanism, a pulley transmission mechanism, or a cylinder mechanism. The output end of the moving mechanism is connected to a pallet, and the unloading body 221 is fixed on the pallet. The position of the pallet can be changed by the moving mechanism to realize the movement and transportation of the bolts.

[0046] like Figure 4 As shown, a hexagonal second fixing groove 2212 is provided in the lower material body 221, and this design allows the head of the bolt to be connected to the second fixing groove 2212. Further, a plurality of hexagonal first fixing grooves 2211 are provided in the lower material body 221; the first fixing groove 2211 is located above the second fixing groove 2212. The applicability of the lower material body 221 is improved by providing the second fixing groove 2212 and the first fixing groove 2211 in each lower material body, so that the lower material body can be fixed with bolts of different sizes.
