Currently, in order to improve the surface properties of automotive metal parts, such as anti-oxidation, anti-corrosion, wear resistance, and other surface characteristics, alloy coatings and powder coatings are usually deposited on the surface of metal parts to improve the surface properties of metal parts.

[0003] A Chinese patent with the authorization announcement number CN216514231U in the related art provides an anti-oxidation treatment device for metal part processing, which includes a base and an inner tank. An electroplating tank, a cleaning tank, a drying tank, and a spraying tank are sequentially installed on the upper surface of the base from left to right. The electroplating tank, the cleaning tank, and the drying tank are all adapted to and movably connected to the inner tank. The metal part to be processed is placed in the inner tank, and the inner tank is immersed in the electroplating solution in the electroplating tank to electroplate the metal part. After the electroplating of the metal part is completed, the inner tank is placed in the cleaning tank to clean the metal part. After the metal part is cleaned, the inner tank is moved to the drying tank to dry the metal part. After the metal part is dried, it is placed in the spraying tank for spraying, so as to achieve the electroplating and spraying effects on the metal part, and deposit the alloy coating and the powder coating on the surface of the metal part.

[0004] In the process of implementing the present application, the inventors found that there are at least the following problems in this technology: Since the operation time required for the same workpiece at different processes is inconsistent, and the number of workpieces that the equipment in the process can process at the same time is limited, in the process with a shorter operation time, the workpiece processing speed is fast, resulting in a situation of supply falling short of demand, and the equipment will often be in an idle state waiting for workpieces to be processed. While in the process with a longer operation time, the workpiece processing speed is slow, resulting in a situation of supply exceeding demand, and there will often be a queuing state of multiple workpieces to be processed, resulting in a large number of workpieces being congested at the slow processing process position, affecting the overall efficiency of the surface treatment of automotive metal parts.

[0064] The process of moving the wire basket 6 from the electroplating tank 11 to the transfer rack 3 is as follows: After the electroplating of automotive metal parts is completed, the output lifting cylinder 81 and the output telescopic cylinder 82 first drive the clamping arm 91 to clamp the hanging seat 62. Then, the output shaft of the output lifting cylinder 81 extends. After moving the wire basket 6 out of the electroplating tank 11, the output shaft of the output lifting cylinder 81 continues to extend until the overlapping arm 64 is inserted into the transfer through slot 31 and the end of the overlapping arm 64 is aligned with the guiding slot 4. Then, the clamping arm 91 is separated from the hanging seat 62, enabling the overlapping arm 64 to be inserted into the guiding slot 4. After that, the output shaft of the output lifting cylinder 81 shortens and waits for the next automotive metal part.

[0065] When there is one cleaning tank 121 or one air drying tank 131, the process of the wire basket 6 flowing between adjacent transfer racks 3 is as follows: The input lifting cylinder 71 and the input telescopic cylinder 72 first drive the clamping arm 91 to clamp the hanging seat 62 on the transfer rack 3. Then, the output shaft of the input lifting cylinder 71 shortens to move the wire basket 6 and place it into the corresponding tank or box. After the wire basket 6 is moved and placed into the corresponding tank or box, the input lifting cylinder 71 and the input telescopic cylinder 72 drive the clamping arm 91 to move away from above the corresponding tank or box. After the processing of automotive metal parts is completed, the output lifting cylinder 81 and the output telescopic cylinder 82 first drive the clamping arm 91 to clamp the hanging seat 62. Then, the output shaft of the output lifting cylinder 81 extends to move the wire basket 6 out of the corresponding tank or box. After that, the output shaft of the output telescopic cylinder 82 shortens to move the wire basket 6 away from above the corresponding tank or box. After the wire basket 6 is moved away from above the corresponding tank or box, the output shaft of the output lifting cylinder 81 continues to extend until the overlapping arm 64 is inserted into the transfer through slot 31 and the end of the overlapping arm 64 is aligned with the guiding slot 4. Then, the output shaft of the output telescopic cylinder 82 extends to move the wire basket 6 to the loading position 411. Finally, the clamping arm 91 is separated from the hanging seat 62, enabling the overlapping arm 64 to be inserted into the guiding slot 4.

[0066] When two or more of the cleaning tank 121, the air-drying tank 131, and the spraying tank 141 are involved, the process of the wire basket 6 flowing between adjacent transfer racks 3 is as follows: The input lifting cylinder 71 and the input telescopic cylinder 72 first drive the clamping arm 91 to clamp the hanging seat 62 on the transfer rack 3. Then, the output shaft of the input lifting cylinder 71 shortens, causing the overlapping arm 64 to move below the transfer rack 3. After that, the output shaft of the input telescopic cylinder 72 shortens. When the wire basket 6 moves above the corresponding tank or box body, the output shaft of the input lifting cylinder 71 continues to shorten, moving the wire basket 6 into the corresponding tank or box body. Finally, the input lifting cylinder 71 and the input telescopic cylinder 72 drive the clamping arm 91 to move away from above the corresponding tank or box body. When the automotive metal parts processing is completed, the output lifting cylinder 81 and the output telescopic cylinder 82 first drive the clamping arm 91 to clamp the hanging seat 62. Then, the output shaft of the output lifting cylinder 81 elongates, moving the wire basket 6 out of the corresponding tank or box body and moving the hanging arm into the transfer through slot 31. After that, the output shaft of the output telescopic cylinder 82 shortens, moving the wire basket 6 away from above the electroplating tank 11. When the wire basket 6 moves away from above the electroplating tank 11, the output shaft of the output lifting cylinder 81 continues to elongate until the overlapping arm 64 is inserted into the transfer through slot 31 and the end of the overlapping arm 64 aligns with the guiding slot 4. Then, the output shaft of the output telescopic cylinder 82 elongates to move the wire basket 6 to the loading position 411. Finally, the clamping arm 91 separates from the hanging seat 62, and the overlapping arm 64 is inserted into the guiding slot 4.

[0067] When there is one spraying tank 141, the process of the wire basket 6 moving from the transfer rack 3 into the spraying tank 141 is as follows: The input lifting cylinder 71 and the input telescopic cylinder 72 first drive the clamping arm 91 to clamp the hanging seat 62 on the transfer rack 3. Then, the output shaft of the input lifting cylinder 71 shortens to separate the wire basket 6 from the transfer rack 3. After that, the operator removes the wire basket 6 from the clamping arm 91 and places the automotive metal parts in the wire basket 6 into the spraying tank 141 for spraying. When the spraying of the automotive metal parts is completed, the operator takes out the finished automotive metal parts after surface treatment.

[0068] When there are two or more spraying tanks 141, the process of the wire basket 6 moving from the transfer rack 3 into the spraying tank 141 is as follows: The input lifting cylinder 71 and the input telescopic cylinder 72 first drive the clamping arm 91 to clamp the hanging seat 62 on the transfer rack 3. Then, the output shaft of the input lifting cylinder 71 shortens, causing the overlapping arm 64 to move below the transfer rack 3. After that, the output shaft of the input telescopic cylinder 72 shortens. When the wire basket 6 moves above the corresponding tank or box body, the operator removes the wire basket 6 from the clamping arm 91 and then places the automotive metal parts in the wire basket 6 into the spraying tank 141 for spraying. When the spraying of the automotive metal parts is completed, the operator takes out the finished automotive metal parts after surface treatment.

[0069] To enable the clamping arm 91 to clamp the hanging seat 62 tightly, refer to Figures 1 to 7, a driving groove 92 is formed in the clamping seat 9. A driving motor 921 is installed in the driving groove 92. A forward lead screw 922 is installed on the output shaft of the driving motor 921. A reverse lead screw 923 is installed on the forward lead screw 922. The reverse lead screw 923 is rotatably connected to the inner wall of the driving groove 92. Driving blocks 924 are threadedly connected to both the forward lead screw 922 and the reverse lead screw 923. The driving blocks 924 are slidably arranged in the driving groove 92. One of the driving blocks 924 is welded to one of the clamping arms 91, and the other driving block 924 is welded to the other clamping arm 91. Clamping grooves 911 are formed on the opposite surfaces of the clamping arms 91. A plurality of clamping cylinders 912 are installed on the opposite surfaces of the clamping grooves 911. Clamping plates 913 are installed on the output shafts of the clamping cylinders 912. When the driving motor 921 is started, it drives the forward lead screw 922 and the reverse lead screw 923 to rotate synchronously. Since the threads of the forward lead screw 922 and the reverse lead screw 923 are opposite, the clamping arms 91 are synchronously moved closer to each other or synchronously moved away from each other, and the output shafts of the clamping cylinders 912 are cooperated to drive the clamping plates 913 to move, so as to achieve the effect that the clamping plates 913 are abutted against the side wall of the hanging seat 62, and the purpose of clamping the hanging seat 62 by the clamping arms 91 is achieved.

[0070] In order to reduce the interference between the wire basket 6 and the input lifting cylinder 71, the input telescopic cylinder 72, the output lifting cylinder 81 and the output telescopic cylinder 82, refer to Figures 1 to 4The guide groove 4 includes a first horizontal section 41, a second vertical section 42, a third horizontal section 43 and a fourth vertical section 44.

The output telescopic cylinder 82 is located below the first horizontal section 41, and the length of the output telescopic cylinder 82 is less than the length of the first horizontal section 41.
