[0052] The travelling device 300 is used for moving between the electrophoresis station and the second transfer station and can lift the lifting arm beam 102 on the second transfer station.

[0053] When the automatic transfer system is used, the load beam assembly 101 of the lifting device 100 is used to connect with the accumulation and release chain device 400, the two ends of the cantilever beam 102 for carrying the workpiece to be electrophoresed 500 are overlapped on the load beam assembly 101, then the lifting device 100 and the workpiece to be electrophoresed 500 on the lifting device 100 can be transferred to the first transfer station through the accumulation and release chain device 400, the transfer device 200 can be moved to the first transfer station through the transfer vehicle body 201, and the lifting mechanism 202 can be controlled to lift and raise the cantilever beam 102 on the first transfer station, so that the cantilever beam 102 can be separated from the load beam assembly 101 on the first transfer station, and then the transfer vehicle body 201 is controlled to move to the second transfer station, then the cantilever beam 102 and the workpiece to be electrophoresed 500 on the cantilever beam 102 can be transferred from the first transfer station to the second transfer station through the transfer device 200, the crane device 300 can be moved to the second transfer station to lift the cantilever beam 102 and the workpiece to be electrophoresed 500 on the cantilever beam 102, and then moved to the electrophoresis station, so that the workpiece to be electrophoresed 500 on the cantilever beam 102 can be immersed in the electrophoresis tank for electrophoresis operation, then the cantilever beam 102 and the workpiece to be electrophoresed 500 on the cantilever beam 102 can be transferred from the second transfer station to the electrophoresis station through the crane device 300, the combination of the lifting device 100, the transfer device 200 and the crane device 300 can realize the automatic transfer of the workpiece to be electrophoresed 500 from the accumulation and release chain device 400 to the electrophoresis station, compared with the manual transfer mode using the crane, the transfer efficiency is obviously improved, the safety is higher, and in addition, compared with the mode of transferring the cut-off accumulation and release chain device 400 and the workpiece to be electrophoresed 500 as a whole by the crane, the lifting weight is obviously reduced, and the energy consumption is reduced.

[0054] It should be particularly pointed out that the workpiece to be electrophoresed 500 in the application is particularly suitable for large truss structural members, but is not limited to large truss structural members, and other structural members are also possible. Specifically, a plurality of hanger hooks can be arranged on the cantilever beam 102 at intervals, so as to carry one large workpiece to be electrophoresed 500, or to carry a plurality of small workpieces to be electrophoresed 500 respectively.

[0055] Referring to Figure 2 and Figure 3In the embodiment of the present application, the cantilever beam 102 comprises a first cross beam body 103, two first vertical connecting rods 104 and two lapping cross bars 105. The first cross beam body 103 is used to carry the workpiece 500 to be electrophoresed. The two first vertical connecting rods 104 are oppositely and spacedly arranged at the upper end of the first cross beam body 103 and vertically extended. The two lapping cross bars 105 are correspondingly arranged at the upper end of the two first vertical connecting rods 104 and transversely extended towards each other, that is, the two lapping cross bars 105 are both transversely extended from the corresponding first vertical connecting rod 104 towards the inner side of the two first vertical connecting rods 104. The two ends of the load beam assembly 101 are both formed with lapping spaces for correspondingly accommodating the two lapping cross bars 105. Compared with directly lapping the first cross beam body 103 on the load beam assembly 101, the lapping of the first cross beam body 103 on the load beam assembly 101 through the additional lapping cross bars 105 is more convenient for the lifting mechanism 202 to lift the cantilever beam 102. Meanwhile, the number of the lapping cross bars 105 is two and correspondingly lapped in the lapping spaces of the two ends of the load beam assembly 101, so as to ensure the stability of the lapping.

[0056] Specifically, the length of the first cross beam body 103 can be greater than the length of the two ends of the load beam assembly 101 forming the lapping spaces, that is, the length of the first cross beam body 103 can be greater than the length of the second cross beam body 110. The distance between the two first vertical connecting rods 104 is greater than or equal to the length of the second cross beam body 110. In order to enable the lifting mechanism 202 to lift the cantilever beam 102 to the position that the lapping cross bars 105 are completely above the lapping spaces, the height of the first vertical connecting rod 104 should be greater than the height of the lapping space. In addition, in order to facilitate the lapping cross bars 105 to be lapped in the lapping spaces of the ends of the load beam assembly 101, the lapping space has an end side opening and an upper side opening.

[0057] In the embodiment of the present application, the lapping cross bar 105 and the lapping space can be an inverted isosceles trapezoidal mortise and tenon structure. Specifically, the vertical cross-sectional shape of the lapping cross bar 105 is an inverted isosceles trapezoid, which is a tenon part of the mortise and tenon structure. The vertical cross-sectional shape of the lapping space is an inverted isosceles trapezoid, which is a groove part of the mortise and tenon structure, so as to facilitate lapping and lifting guidance and further improve the stability of lapping.

[0058] Please refer again to Figure 1In the embodiment of the present application, the load beam assembly 101 comprises two first load beams 108, the two first load beams 108 are spaced apart, and the two ends of the two first load beams 108 are respectively used for being connected with the accumulator chain device 400. The second load beam 109 comprises a second cross beam body 110 and two second vertical connecting rods 111, the two ends of the second cross beam body 110 are formed with overlapping spaces, and the two second vertical connecting rods 111 are oppositely and spaced apart arranged at the upper end of the second cross beam body 110 and are one-to-one connected with the two first load beams 108. The two ends of the two first load beams 108 are respectively connected with the accumulator chain device 400, so that the stability of the horizontal placement of the two first load beams 108 can be ensured. The second cross beam body 110 for overlapping the boom beam 102 is one-to-one connected with the two first load beams 108 through the two second vertical connecting rods 111, so that the stability of the horizontal placement of the second cross beam body 110 and the reliability of the hoisting movement can be further ensured. It should be particularly pointed out that the two second vertical connecting rods 111 should be located between the overlapping spaces at the two ends of the second cross beam body 110, so that the two second vertical connecting rods 111 will not interfere with the overlapping of the boom beam 102.

[0059] In the embodiment of the present application, the number of the lifting mechanisms 202 is two, the two lifting mechanisms 202 are oppositely and spaced apart arranged on the transfer trolley body 201, and are used for one-to-one lifting and raising the two ends of the first cross beam body 103, so that the lifting and raising of the lifting mechanisms 202 and the stability and reliability of the movement of the transfer trolley body 201 can be ensured. Of course, the present application is not limited to this, and the number of the lifting mechanisms 202 can also be one or more than three.

[0060] As Figure 3 and Figure 4As shown, in the embodiment of the present application, the lifting mechanism 202 comprises a fixed mounting frame 203 fixedly arranged on the transfer vehicle body 201, a movable lifting frame 204 arranged on the fixed mounting frame 203 in a liftable manner, and a lifting driving member 205 mounted on the fixed mounting frame 203 and drivingly connected with the movable lifting frame 204, the end of the first beam body 103 downwardly extends and is provided with two oppositely spaced support portions 112, and the upper end of the movable lifting frame 204 is formed with two support spaces corresponding to the two support portions 112. That is, when the accumulation chain device 400 drives the lifting device 100, the workpiece 500 to be electrophoresed on the lifting device 100, and the transfer device 200 to move to the first transfer station, the transfer device 200 is located directly below the lifting device 100, the lifting driving member 205 of the lifting mechanism 202 can drive the movable lifting frame 204 to move upward to gradually approach the support portions 112 on the first beam body 103, until the bottom wall of the support space abuts against the support portion 112, then the movable lifting frame 204 can support the lifting arm beam 102 to be lifted, until the overlapping cross bar 105 of the lifting arm beam 102 is completely located above the overlapping space, the whole lifting operation is completed, and then by additionally arranging the support portions 112 on the first beam body 103 and the support spaces on the movable lifting frame 204, the docking accuracy of the lifting operation can be ensured, and the stability of the support can also be ensured.

[0061] Specifically, the first end of the first beam body 103 downwardly extends and is provided with two oppositely spaced support portions 112, the second end of the first beam body 103 downwardly extends and is provided with two oppositely spaced support portions 112, that is, the upper end of the movable lifting frame 204 of the lifting mechanism 202 corresponding to the first end of the first beam body 103 to be lifted is formed with two support spaces, and the upper end of the movable lifting frame 204 of the lifting mechanism 202 corresponding to the second end of the first beam body 103 to be lifted is formed with two support spaces. Further, the support portion 112 and the support space can also be an inverted isosceles trapezoidal tenon and groove cooperation structure, and the lifting driving member 205 can be a hydraulic oil cylinder.

[0062] Referring to Figure 5In the embodiment of the present application, the travelling device 300 comprises a translation vehicle body 301, a lifting frame 302 and a lifting mechanism 303. The translation vehicle body 301 is horizontally movably installed on the factory overhead rail. The lifting frame 302 is vertically movably installed on the translation vehicle body 301 and forms a lifting space 308 for horizontally abutting and lifting the cross connecting rod 105. The lifting mechanism 303 is arranged on the translation vehicle body 301 and is drivingly connected with the lifting frame 302. That is, before the travelling device 300 moves to the second transfer station, the lifting mechanism 303 is controlled to drive the lifting frame 302 to descend to the same horizontal position as the cross connecting rod 105 in the lifting space 308, and then the translation vehicle body 301 is controlled to move horizontally on the factory overhead rail, so that when the travelling device 300 moves to the second transfer station, the cross connecting rod 105 is in the lifting space 308, and then the lifting mechanism 303 is controlled to drive the lifting frame 302 to ascend. Since the lifting space 308 is clamped to the cross connecting rod 105, the boom beam 102 and the workpiece 500 to be electrophoresed on the boom beam 102 can ascend with the lifting frame 302, and the abutting and lifting operation is completed.

[0063] Referring to Figure 3 , Figure 5 and Figure 6 In the embodiment of the present application, the cross connecting rod 105 comprises a first cross connecting portion 106 and a second cross connecting portion 107 which are arranged on the first vertical connecting rod 104 in a bidirectional extending manner. The first cross connecting portion 106 is located on the inner side of the first vertical connecting rod 104 and can be used to connect in the cross connecting space of one end of the load beam assembly 101. The second cross connecting portion 107 is located on the outer side of the first vertical connecting rod 104. The lifting frame 302 comprises a frame body 304 and a lifting seat 305. The frame body 304 is vertically movably installed on the translation vehicle body 301. The lifting seat 305 comprises two connecting vertical rods 306 and two connecting horizontal rods 307. The two connecting vertical rods 306 are oppositely arranged on the lower end of the frame body 304 and vertically extend. The two connecting horizontal rods 307 are correspondingly arranged on the two connecting vertical rods 306 and extend towards each other in a horizontal direction. The lifting space 308 is formed between the two connecting vertical rods 306. The two connecting horizontal rods 307 form a gap 309 through which the first vertical connecting rod 104 passes, and the two connecting horizontal rods 307 are used to support the first cross connecting portion 106 and the second cross connecting portion 107 correspondingly. During the movement of the travelling device 300 to the second transfer station, the entire cross connecting rod 105 gradually enters the lifting space 308, the first vertical connecting rod 104 gradually enters the gap 309, and then the lifting mechanism 303 is controlled to drive the lifting frame 302 to ascend. The two connecting horizontal rods 307 ascend to abut against the first cross connecting portion 106 and the second cross connecting portion 107 respectively, so as to realize the clamping of the lifting seat 305 to the cross connecting rod 105, thereby ensuring the stability of the lifting operation.

[0064] In the embodiment of the present application, the automatic transfer system further comprises a control device, which comprises a controller, a stopper, a first position detector and a second position detector. The controller is in communication connection with the transfer device 200, the travelling crane device 300, the stopper, the first position detector and the second position detector respectively. The stopper is used to be installed on the accumulation chain device 400 and to control the accumulation chain device 400 to stop moving in the case that the workpiece 500 to be electrophoresed is transferred to the first transfer station. The first position detector and the second position detector are respectively arranged at the first transfer station and the second transfer station and are both used to detect the position of the transfer device 200. Specifically, when the accumulation chain device 400 drives the lifting device 100 and the workpiece 500 to be electrophoresed on the lifting device 100 to reach the first transfer station, the stopper can not only control the accumulation chain device 400 to stop moving, but also send a first position signal to the controller, so that the controller continues to control the transfer device 200 to move to the first transfer station. The first position detector is arranged at the first transfer station, so that after the transfer vehicle body 201 of the transfer device 200 moves to the position, the first position detector can send a second position signal to the controller, so that the controller continues to control the lifting mechanism 202 to lift the lifting arm beam 102. The lifting mechanism 202 stops lifting after reaching the preset lifting height. After the lifting mechanism 202 reaches the preset lifting height, the overlapping cross bar 105 of the lifting arm beam 102 is located above the overlapping space. At this time, the controller can continue to control the transfer device 200 to move to the second transfer station. The second position detector is arranged at the second transfer station, so that after the transfer vehicle body 201 moves to the position, the second position detector can send a third position signal to the controller, so that the controller continues to control the travelling crane device 300 to move to the second transfer station and hoist the lifting arm beam 102 at the second transfer station to the electrophoresis station. The whole transfer process is fully automated and does not need manual control.

[0065] To achieve the above object, the present application further provides an automatic transfer method, wherein the automatic transfer method is applied to the automatic transfer system according to the above description and comprises the following steps.

[0066] Step one, control the accumulation chain device 400 to drive the lifting device 100 and the workpiece 500 to be electrophoresed on the lifting device 100 to be transferred to the first transfer station.

[0067] Specifically, the first transfer station, the second transfer station and the electrophoresis station are arranged in parallel and at intervals, and the accumulator chain device 400 drives the lifting device 100 and the workpiece 500 on the lifting device 100 to be transferred to the upper space of the first transfer station. At the same time, the position of the lifting device 100 can be detected by the stopper on the accumulator chain device 400 to determine whether the lifting device 100 and the workpiece 500 on the lifting device 100 are in place. Of course, the position of the first transfer station can also be preset to determine whether the lifting device 100 and the workpiece 500 on the lifting device 100 are in place by controlling the movement of the accumulator chain device 400.

[0068] Step two, control the transfer car body 201 to translate to the first transfer station.

[0069] Specifically, when it is determined that the lifting device 100 and the workpiece 500 on the lifting device 100 are transferred to the first transfer station, the transfer car body 201 is controlled to translate to the lower space of the first transfer station, so that the lifting mechanism 202 is located directly below the lifting device 100.

[0070] Step three, control the lifting mechanism 202 to lift and raise the lifting arm beam 102, so that the lifting arm beam 102 is separated from the load beam assembly 101.

[0071] Further, after the first position detector detects that the transfer car body 201 translates to the first transfer station, the lifting drive 205 of the lifting mechanism 202 can drive the movable lifting frame 204 to move upward and lift and raise the lifting arm beam 102 until the overlapping cross bar 105 of the lifting arm beam 102 is completely located above the overlapping space, and the lifting arm beam 102 is completely separated from the load beam assembly 101.

[0072] Step four, control the transfer car body 201 to translate to the second transfer station.

[0073] Further, since the overlapping cross bar 105 of the lifting arm beam 102 is completely located above the overlapping space, the transfer car body 201 can be smoothly translated to the lower space of the second transfer station.

[0074] Step five, control the crane device 300 to translate to the second transfer station and lift the lifting arm beam 102 on the second transfer station.

[0075] More specifically, when the second transfer station detector detects that the transfer vehicle 201 has been translated to the second transfer station, the lifting mechanism 303 of the travelling device 300 is first controlled to perform a lowering movement so that the lifting space 308 on the lifting frame 302 is at the same horizontal position as the overlapping cross bar 105 on the beam 102, and then the travelling device 300 is controlled to translate to the upper space of the second transfer station, and the overlapping cross bar 105 can enter the overlapping space, so that the lifting mechanism 303 of the travelling device 300 can lift the beam 102 on the transfer device 200 and the workpiece 500 to be electrophoresed on the beam 102.

[0076] Step six, the travelling device 300 is controlled to translate to the electrophoresis station and lower the workpiece 500 to be electrophoresed on the beam 102 into the electrophoresis tank.

[0077] Further, after the lifting mechanism 303 of the travelling device 300 lifts the beam 102 and the workpiece 500 to be electrophoresed on the beam 102, the translation vehicle 301 of the travelling device 300 can translate from the second transfer station to the electrophoresis station, so that the beam 102 and the workpiece 500 to be electrophoresed on the beam 102 are located directly above the electrophoresis tank, and then the lifting mechanism 303 is controlled to lower the beam 102 and the workpiece 500 to be electrophoresed on the beam 102, so that the workpiece 500 to be electrophoresed is completely submerged in the electrophoresis tank.
