DETAILED DESCRIPTION

[0033] The technical solutions of the present application will be described in detail below in combination with the drawings and specific embodiments, so that the advantages and features of the present application are easier for those skilled in the art to understand. Obviously, the embodiments described in the present application are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0034] A carrier circulation system, a carrier 1 has an empty state of not loading a piece to be electroplated and a full state of loading a piece to be electroplated, the circulation system comprises a circulation loop 10, the carrier 1 circulates in the circulation loop 10 along the transmission direction. The circulation loop 10 is provided with a feeding station, an electroplating tank 2 and a discharging station, the feeding station, the electroplating tank 2 and the discharging station are sequentially distributed along the transmission direction. Among them, the feeding station is provided with a loading mechanism 3, the loading mechanism 3 is used for converting the carrier 1 in the empty state to the full state; the piece to be electroplated is subjected to electroplating operation in the electroplating tank 2; the discharging station is provided with an unloading mechanism 4, the unloading mechanism 4 is used for converting the carrier 1 in the full state to the empty state.

[0035] In the embodiment, referring to Figure 2 The carrier 1 is transmitted along the clockwise direction in the circulation loop 10. When the carrier 1 in the empty state is transmitted to the feeding station, the loading mechanism 3 loads the piece to be electroplated on the carrier 1, and then the carrier 1 in the full state is transmitted to the electroplating tank 2 and completes the electroplating operation in the electroplating tank 2. After the electroplating is completed, the carrier 1 continues to transmit to the discharging station, when it is transmitted to the discharging station, the unloading mechanism 4 unloads the piece to be electroplated on the carrier 1, and then the carrier 1 continues to transmit forward and is transmitted to the feeding station again, so that the circulation of the carrier 1 is completed, and the circulation of the next carrier 1 is started.

[0036] In the embodiment, the feeding station comprises a plurality of feeding stations arranged side by side, and each feeding station is provided with a loading mechanism 3, the carrier 1 can be transmitted to different feeding stations for loading operation, and the circulation system can simultaneously load the pieces to be electroplated on a plurality of carriers 1 in the empty state, thereby improving the efficiency and avoiding the accumulation and blockage of a large number of carriers 1 behind the feeding station with only one feeding station, thereby avoiding affecting the normal circulation of the circulation loop 10.

[0037] In the embodiment, the circulation loop 10 comprises a feeding transmission section arranged between the feeding stations and the electroplating tank 2. The feeding transmission section is provided with a first converging station 101. The carriers 1 at the plurality of feeding stations are transmitted along different transmission paths to the first converging station 101, respectively. The carriers at the first converging station 101 are transmitted to the feeding end of the electroplating tank 2. The loading times of the different feeding stations can be staggered. When one of the feeding stations is performing a loading operation, the carriers 1 loaded by the other feeding stations can be transmitted to the electroplating tank 2, so that the electroplating tank 2 is continuously fed. Alternatively, the plurality of feeding stations can perform loading operations simultaneously. When the loading mechanism 3 performs loading operations on a group of carriers 1, the carriers 1 loaded in the previous group are transmitted to the feeding end of the electroplating tank 2 one by one. When the carriers 1 in the previous group enter the electroplating tank 2, the loading mechanism 3 also completes the loading operation. Thus, the loading operation of the loading mechanism 3 is seamlessly connected with the feeding of the electroplating tank 2, so that the efficiency is maximized. The electroplating tank 2 is effectively prevented from being unable to receive the carriers 1 in the full load state for a long time due to the long operation time of the loading mechanism 3.

[0038] In the embodiment, each feeding station is provided with a feeding transmission path. The plurality of feeding transmission paths are arranged side by side. Thus, the structure of the circulation system is more compact. Specifically, the feeding stations comprise two feeding stations arranged side by side. The feeding transmission paths comprise a first transmission path and a second transmission path. The first transmission path and the second transmission path are arranged between the two feeding stations and the first converging station 101, respectively. In the embodiment, the electroplating tank 2 is arranged on the extension of the first transmission path. The carriers 1 in the full load state can be directly transmitted to the electroplating tank 2 along the first transmission path. The second transmission path is provided with a first temporary storage station 102. The first temporary storage station 102 is arranged side by side with the first converging station 101. When the carriers 1 are transmitted along the second transmission path, the carriers 1 are first transmitted to the first temporary storage station 102. Then, the carriers 1 are transmitted from the first temporary storage station 102 to the first converging station 101 and then to the electroplating tank 2. The carriers 1 can be temporarily stopped at the first temporary storage station 102, so that the carriers 1 are transmitted in an orderly manner.

[0039] In the embodiment, the circulation system comprises a first transfer mechanism 103 for transferring the carriers 1. The first transfer mechanism 103 is arranged between the first temporary storage station 102 and the first converging station 101 in a reciprocating manner. The first transfer mechanism 103 can transmit the carriers 1 in the transmission direction. The first transfer mechanism 103 not only transfers the carriers 1 between the first temporary storage station 102 and the first converging station 101, but also transmits the carriers 1 in the transmission direction. Thus, after the carriers 1 in the first temporary storage station 102 are transferred to the first converging station 101, the first transfer mechanism 103 can directly transmit the carriers 1 in the transmission direction, so that the carriers 1 are quickly transmitted to the electroplating tank 2, thereby improving the efficiency.

[0040] Referring to Figure 4 In the embodiment shown, the carrier 1 comprises a mounting plate 11, and a fixing space 14 for loading the parts to be electroplated is formed in the lower part of the mounting plate 11. Referring to Figure 5 In the embodiment shown, the first transfer mechanism 103 comprises a first transmission frame 1031 extending along the transmission direction, a first support 1032 fixedly arranged below the first transmission frame 1031, a first sliding block 1033 fixedly arranged at the lower end of the first support 1032, and a first guide rail 1034 extending perpendicularly to the transmission direction, and the first transmission frame 1031 comprises two groups arranged in parallel, and the first sliding block 1033 is slidingly arranged on the first guide rail 1034. Figure 6 In the embodiment shown, when the carrier 1 is transmitted or transferred, the mounting plate 11 of the carrier 1 is supported on the two first transmission frames 1031, and the first transmission frames 1031 can be transmitted forward along the transmission direction, so as to drive the carrier 1 to move forward along the transmission direction, or the first sliding block 1033 can be driven to slide along the first guide rail 1034, so as to drive the carrier 1 to transfer between the first temporary storage station 102 and the first converging station 101.

[0041] In the embodiment shown, the first converging station 101 is provided with a first detector 104 for detecting whether the carrier 1 in the full load state is abnormal, so that all the carriers 1 transmitted to the first converging station 101 can be detected, and the abnormal carrier 1 can be prevented from entering the electroplating tank 2. In the embodiment shown, a maintenance station 105 is arranged in the circulation system, the maintenance station 105 is adjacent to the first temporary storage station 102, and the maintenance station 105 is located downstream of the first temporary storage station 102 along the transmission direction. When the first detector 104 detects the abnormal carrier 1, the abnormal carrier 1 is transferred to the first temporary storage station 102 by the first transfer mechanism 103, and then the function of transmitting the carrier 1 forward along the transmission direction by the first transfer mechanism 103 can be used to directly transmit the abnormal carrier 1 to the maintenance station 105. The carrier 1 transferred to the maintenance station 105 is maintained and cleaned by the technician, and after the abnormality is eliminated, the carrier 1 can be transferred from the maintenance station 105 to the first temporary storage station 102, and then transferred from the first temporary storage station 102 to the first converging station 101 by the first transfer mechanism 103, so as to return to the circulation loop 10.

[0042] In the embodiment shown, the unloading stations are arranged side by side, and the circulation loop 10 comprises an unloading transmission section arranged between the electroplating tank 2 and the plurality of unloading stations, and the unloading transmission section is provided with a first shunt station 111, the carrier 1 is transmitted from the unloading end of the electroplating tank 2 to the first shunt station 111, and the carriers 1 at the first shunt station 111 are transmitted along different transmission paths to the plurality of unloading stations, respectively. In some embodiments, only a plurality of loading stations are arranged side by side, or only a plurality of unloading stations are arranged side by side.

[0043] In the embodiment, the circulation loop 10 is located in a vertical plane, and the circulation loop 10 has an electroplating processing section 100 for transporting the carrier 1 in a full load state along a horizontal extension direction of the transportation direction, a lifting section 200 for transporting the carrier 1 upward, a horizontal transportation section 300 for transporting the carrier 1 in an empty load state along a horizontal extension direction of the transportation direction, and a backflow section 400 for transporting the carrier 1 downward. Referring to Figure 2 As shown, the horizontal transportation section 300 is located above the electroplating processing section 100, and the electroplating processing section 100, the lifting section 200, the horizontal transportation section 300, and the backflow section 400 are sequentially connected. The electroplating tank 2 is located in the electroplating processing section 100, the unloading station is located in the lifting section 200, and the loading station is located in the backflow section 400. Such an arrangement can greatly reduce the occupation of the carrier circulation system to the factory floor, thereby achieving the effect of saving the occupation of the factory floor.

[0044] Referring to Figure 2 Figure 3 As shown, in the embodiment, the circulation loop 10 includes two backflow sections 400 arranged side by side, and each backflow section 400 is provided with a loading station. The two loading stations are arranged side by side.

[0045] In some embodiments, the circulation loop 10 includes a plurality of lifting sections 200 arranged side by side, and the unloading transportation path is arranged between the first shunt station 111 and each lifting section 200. The plurality of unloading transportation paths are arranged side by side. In the embodiment, the circulation loop 10 includes two lifting sections 200 arranged side by side, and the unloading transportation path includes a third transportation path and a fourth transportation path. The third transportation path and the fourth transportation path are respectively located between the first shunt station 111 and the two lifting sections 200. After being electroplated by the electroplating tank 2, the carrier 1 can be shunted at the first shunt station 111, and then transported along the third transportation path and the fourth transportation path side by side to improve the transportation efficiency. Specifically, the electroplating tank 2 is located on the extension section of the third transportation path, and the carrier 1 at the unloading end of the electroplating tank 2 can be directly transported into the third transportation path along the transportation direction and transported to the lifting section 200. The second temporary storage station 112 is arranged in the fourth transportation path, and the second temporary storage station 112 is arranged side by side with the first shunt station 111. After part of the carrier 1 is transported to the first shunt station 111, the carrier 1 is transported to the second temporary storage station 112, and then transported to the lifting section 200 along the fourth transportation path, and finally transported to the unloading station.

[0046] In the embodiment, the circulation system has a second transfer mechanism, which can be reciprocally arranged between the second temporary storage station 112 and the first shunt station 111, and the second transfer mechanism can transport the carrier 1 along the transportation direction. In the embodiment, the second transfer mechanism is similar in structure and principle to the first transfer mechanism 103, and will not be described in detail here.

[0047] ​In the embodiment, the horizontal conveying section 300 is provided with a detection station 301, the detection station 301 is provided with a second detector 303 for detecting whether the carrier 1 in the empty state is abnormal, and the circulating system is provided with a transfer device for transferring the abnormal carrier 1 from the detection station 301 to the repair station 105. Specifically, the horizontal conveying section 300 is provided with a carrying station 302, when the second detector 303 detects that there is an abnormal carrier 1, the abnormal carrier 1 is first transferred to the carrying station 302 by the transfer device, so that the abnormal carrier 1 is separated from the circulating loop 10. The electroplating processing section 100 is provided with a receiving station 106, the carrying station 302 is located above the receiving station 106, and the transfer device includes an abnormal carrier carrying mechanism for transferring the carrier 1, and the abnormal carrier carrying mechanism can reciprocate between the carrying station 302 and the receiving station 106. The transfer device further includes a third transfer mechanism 107 for transferring the carrier 1, and the third transfer mechanism 107 can reciprocate between the receiving station 106 and the repair station 105. When the abnormal carrier 1 is transferred to the carrying station 302, it can be transferred to the receiving station 106 by the abnormal carrier carrying mechanism, and then the abnormal carrier 1 is transferred to the repair station 105 by the third transfer mechanism 107. The carrier 1 in the empty state after the abnormality is eliminated can be transferred to the receiving station 106 by the third transfer mechanism 107, and then transferred to the carrying station 302 by the abnormal carrier carrying mechanism, and then transferred to the detection station 301 by the transfer device, so as to return to the circulating loop 10.

[0048] In the embodiment, as shown in Figure 2 The receiving station 106 and the repair station 105 are arranged adjacent to each other, and the receiving station 106 is located downstream of the repair station 105 along the conveying direction, and the repair station 105 is located between the first temporary station 102 and the receiving station 106 along the conveying direction. In this way, the structure of the circulating system is more compact, and the conveying path of the carrier 1 is shorter, and the conveying time is shorter, so that the efficiency is higher.

[0049] In the embodiment, as shown in Figure 7 The third transfer mechanism 107 includes a second conveying frame 1071 extending along the conveying direction, a second bracket 1072 fixedly arranged at the lower part of the second conveying frame 1071, a second sliding block 1073 fixedly arranged at the lower end of the second bracket 1072, and a second guide rail 1074 along the conveying direction. The second conveying frame 1071 also includes two groups arranged in parallel, and the second sliding block 1073 is slidingly arranged on the second guide rail 1074. The second conveying frame 1071 can drive the carrier to move from the repair station 105 to the first temporary station 102, that is, the second conveying frame 1071 can convey the carrier 1 in the opposite direction along the conveying direction, and through the cooperation between the second sliding block 1073 and the second guide rail 1074, the third transfer mechanism 107 can be transferred between the receiving station 106 and the repair station 105.

[0050] In the embodiment, the lifting section 200 is provided with a plurality of unloading stations in the up-down direction, and each unloading station is provided with an unloading mechanism 4.

The circulation loop 10 includes a branch transmission section between the jacking station 108 and the unloading station, and part of the carriers 1 are transmitted along the branch transmission section from the jacking station 108 to the unloading station. The full-load carrier 1 can continue to transmit forward along the transmission direction after leaving the electroplating tank 2 and enter the lifting section 200, and then reach the unloading station. Meanwhile, the carrier 1 can also enter the branch transmission section after reaching the jacking station 108 and be transmitted to the unloading station through the branch transmission section. Since the unloading mechanism 4 needs time to unload the workpiece to be electroplated, the carrier 1 can be shunted when it is transmitted to the jacking station 108, so that the carrier 1 can be transmitted to different unloading stations through different paths, which can avoid the congestion of the rear carrier 1 due to waiting for the unloading of the front carrier 1.

[0051] In the embodiment, the branch transmission section is provided with a transfer station 109, and the transfer station 109 is located above the jacking station 108 and at the same height as the unloading station. The circulation system is provided with a jacking transmission mechanism 110, which can transmit the carrier 1 along the transmission direction, and the jacking transmission mechanism 110 can be reciprocatingly arranged between the jacking station 108 and the transfer station 109. The circulation system also includes a horizontal transmission mechanism for transmitting the carrier 1 in the horizontal direction, and the horizontal transmission mechanism is arranged between the transfer station 109 and the unloading station. When the carrier 1 is transmitted to the jacking station 108, it can continue to transmit forward to the lifting section 200 under the drive of the jacking transmission mechanism 110, or it can move upward to the transfer station 109 under the drive of the jacking transmission mechanism 110. After reaching the transfer station 109, the jacking transmission mechanism 110 can transmit the carrier 1 to the horizontal transmission mechanism, and the carrier 1 can be transmitted to the unloading station under the drive of the horizontal transmission mechanism.

[0052] In the embodiment, as shown in Figure 8 The jacking transmission mechanism 110 includes a lifting assembly 1101 and a transmission assembly 1102 fixedly arranged on the upper part of the lifting assembly 1101. The lifting assembly 1101 is used to drive the transmission assembly 1102 to move up and down, and the transmission assembly 1102 can transmit the carrier 1 along the transmission direction.

[0053] In the embodiment, the horizontal transmission mechanism and the third transfer mechanism 107 are similar in structure and principle. The horizontal transmission mechanism is achieved by cooperation between the sliding block and the guide rail to realize the movement of the mechanism in the horizontal direction, and to complete the transfer of the carrier 1 between different stations. The horizontal transmission mechanism also realizes the horizontal transmission of the carrier 1 through the transmission frame. The specific structure of the horizontal transmission mechanism is not described here.

[0054] In the embodiment, the lifting section 200 includes two sections arranged side by side, and each lifting section 200 is provided with a plurality of unloading stations. The unloading stations on the two lifting sections 200 are arranged side by side. Specifically, in the embodiment, each lifting section 200 is provided with two unloading stations.

[0055] In the embodiment, the horizontal transmission section 300 includes a first section 310 capable of side-by-side transmission, a second section 320 capable of single-row transmission, and a third section 330 capable of side-by-side transmission.
