Description

Technical Field

[0002] Currently, in the photovoltaic industry, when manufacturing metal grid lines for photovoltaic cells on electroplating production lines, electroplating racks carry the cells along the line, and electroplating is completed by the electroplating equipment. During the electroplating process, current needs to be transmitted to the plating solution through the electroplating racks. When the resistance of the electroplating racks is abnormal, it will lead to abnormal current, thus affecting the electroplating effect.

[0003] Commercially available electroplating production lines cannot perform resistance testing on the electroplating racks flowing on the production line. They can only perform manual testing after the electroplating racks come off the line, which is inefficient and cannot guarantee the reliability of the electroplating racks on the line.

[0030] Example

[0031] Please see Figure 1 , Figure 1 The diagram shown is a structural schematic of the electroplating rack resistance detection device 100 provided in this embodiment in practical application.

[0032] The electroplating fixture resistance detection device 100 provided in this embodiment is used to detect the resistance of the electroplating fixture 200 on the electroplating production line. On the electroplating production line, the electroplating fixture 200 is movably mounted on the support rail 300. The electroplating fixture 200 is used to hold and fix the battery cells and drive the battery cells to move along the support rail 300, realizing their circulation on the production line. During this process, the electroplating equipment below the support rail 300 electroplats the battery cells to grow grid lines.

[0033] The electroplating fixture 200 has a conductive block 210 and multiple conductive clips 220 electrically connected to the conductive block 210 for holding the battery cells. The conductive block 210 is used for electrical connection to a power source. In practical applications, the electroplating equipment has a positive electrode in the plating tank that is electrically connected to the positive terminal of the power source, and the conductive block 210 is electrically connected to the negative terminal of the power source. Current flows through the plating solution to form a closed circuit.

[0034] The electroplating rack resistance testing device 100 provided in this embodiment is arranged at the resistance testing station of the electroplating production line. It includes a testing component and a driving component. The testing component includes a resistance tester 110, an anode probe 120 and a cathode probe 130. The anode probe 120 is electrically connected to the anode of the resistance tester 110, and the cathode probe 130 is electrically connected to the cathode of the resistance tester 110.

[0035] The drive assembly is connected to the anode probe 120 and the cathode probe 130, and is used to drive the anode probe 120 to selectively contact the conductive block 210, and also to drive the cathode probe 130 to selectively contact any one of the multiple conductive clips 220.

[0036] In practical applications, when the electroplating rack 200 moves along the support track 300 to the resistance detection station, the drive assembly drives the anode probe 120 to contact the conductive block 210, and drives the cathode probe 130 to contact multiple conductive clips 220 in sequence, thereby detecting the resistance of multiple conductive clips 220 and completing the resistance detection of the electroplating rack 200. The resistance of the electroplating rack 200 can be determined to be normal if the resistance of all conductive clips 220 is within a preset reasonable range, or it can be determined to be abnormal if the resistance of at least one conductive clip 220 exceeds the reasonable range.

[0037] To ensure the stability of the testing process and thus the accuracy and reliability of the test results, the electroplating rack resistance testing device 100 provided in this embodiment also includes a locking component. The locking component is used to cooperate with the electroplating rack 200 to lock the electroplating rack 200, and is also used to disengage from the electroplating rack 200 to release the locking of the electroplating rack 200.

[0038] Specifically, the locking assembly includes a gantry frame 180 and a locking drive 190. The gantry frame 180 is positioned above the support rail 300, and the locking drive 190 is mounted on the gantry frame 180 to selectively abut against the electroplating fixture 200.

[0039] In fact, the gantry frame 180 is set at the resistance testing station of the electroplating production line. When the electroplating fixture 200 moves along the support rail 300 to the resistance testing station, the locking drive component 190 on the gantry frame 180 is activated to hold the electroplating fixture 200, thereby locking the electroplating fixture 200 at the resistance testing station.

[0040] In this embodiment, the locking drive 190 is a cylinder, whose piston rod can extend downward to abut against the electroplating hanger 200 before resistance detection, thereby locking the electroplating hanger 200. It can also retract upward to disengage from the electroplating hanger 200 after resistance detection, thereby releasing the lock on the electroplating hanger 200.

[0041] In another embodiment, depending on the actual application conditions, the locking drive 190 may also be a hydraulic cylinder, electric cylinder or other device.

[0042] The electroplating rack resistance detection device 100 provided in this embodiment also includes a controller 191, which is electrically connected to the resistance tester 110. The controller 191 is used to determine the electroplating rack 200 with abnormal resistance based on the detection data of the resistance tester 110.

[0043] In practical applications, the resistance tester 110 sends the measured resistance of each conductive clip 220 to the controller 191. The controller 191 compares the received resistance with the pre-stored resistance range and determines whether the current electroplating fixture 200 has an abnormal resistance problem based on the comparison result.

[0044] Furthermore, the electroplating rack resistance detection device 100 also includes a host computer 192, which is electrically connected to the controller 191. The controller 191 is also used to send the identification information of the electroplating rack 200 with abnormal resistance to the host computer 192, so that the host computer 192 can issue an alarm message.

[0045] If the controller 191 determines that the resistance of the current electroplating rack 200 is abnormal, it sends the identification information of the electroplating rack 200 to the host computer 192. In practical applications, this identification information can be the code of the electroplating rack 200. After receiving the identification information, the host computer 192 issues an alarm message to remind the operator to respond in a timely manner.

[0046] Furthermore, the electroplating fixture resistance detection device 100 also includes a dismounting mechanism, and the host computer 192 is also used to control the dismounting mechanism to dismount the electroplating fixture 200 corresponding to the identity information when it receives the identity information.

[0047] Understandably, the unloading mechanism can be a robotic arm, which can transfer the electroplating rack 200 with abnormal resistance to outside the electroplating production line, that is, remove the electroplating rack 200 from the production line.

[0048] In practical applications, the resistance detection station can be placed before the electroplating station on the electroplating production line to ensure that the resistance of the electroplating fixtures 200 on the production line can be detected before electroplating begins. This allows for the timely removal of electroplating fixtures 200 with abnormal resistance, preventing subsequent electroplating processes from being affected and achieving better electroplating results.

[0049] In this embodiment, the anode probe 120 is located below the support track 300. The driving component is used to drive the anode probe 120 to move upward to contact the conductive block 210, and also to drive the anode probe 120 to move downward to separate from the conductive block 210.

[0050] In fact, the drive assembly includes a fixed bracket 140 and an anode lifting drive 150. The anode lifting drive 150 is mounted on the fixed bracket 140 and connected to the anode probe 120 to drive the anode probe 120 to move.

[0051] By setting the relative positions of the fixed bracket 140 and the anode lifting drive 150 on the electroplating production line, when the electroplating fixture 200 moves to the resistance detection station, the conductive block 210 and the anode probe 120 installed on the anode lifting drive 150 are vertically aligned. At this time, the anode lifting drive 150 is activated, driving the anode probe 120 to move upward until the top of the anode probe 120 contacts the conductive block 210, thereby achieving anode connection between the conductive block 210 and the resistance tester 110.

[0052] In this embodiment, the anode lifting drive 150 is also a cylinder, and the anode probe 120 is connected to its piston rod. In another embodiment, depending on the actual application conditions, the anode lifting drive 150 can also be a hydraulic cylinder, electric cylinder, or other device.

[0053] In fact, the multiple conductive clips 220 on the electroplating rack 200 are arranged sequentially in the first horizontal direction, which is the first horizontal direction. Figure 1 The direction indicated by the X arrow. In this embodiment, the cathode probe 130 is also located below the support track 300, and the driving component is used to drive the cathode probe 130 to move in the first horizontal direction and the vertical direction.

[0054] Specifically, the driving assembly includes a cathode horizontal driving member 160 and a cathode lifting driving member 170. The cathode horizontal driving member 160 is connected to the cathode lifting driving member 170 and is used to drive the cathode lifting driving member 170 to move in a first horizontal direction. The cathode lifting driving member 170 is connected to the cathode probe 130 and is used to drive the cathode probe 130 to move upward until it contacts the conductive clamp 220, and also to drive the cathode probe 130 to move downward until it separates from the conductive clamp 220.

[0055] In practical applications, the cathode horizontal drive 160 drives the cathode lifting drive 170 to move in the first horizontal direction, thereby causing the cathode probe 130 to move between multiple conductive clips 220. When the cathode probe 130 moves to below the conductive clip 220 to be tested, the cathode lifting drive 170 drives the cathode probe 130 to move upward until the cathode probe 130 contacts the conductive clip 220, thus achieving cathode connection between the conductive clip 220 to be tested and the resistance tester 110.

[0056] After completing the resistance detection of the current conductive clip 220, when it is necessary to detect the resistance of the next conductive clip 220, the cathode lifting drive 170 drives the cathode probe 130 to descend until it separates from the current conductive clip 220. Then, the cathode horizontal drive 160 drives the cathode lifting drive 170 to move the cathode probe 130 to below the next conductive clip 220. After that, the cathode lifting drive 170 drives the cathode probe 130 to rise until it contacts the conductive clip 220.

[0057] In this embodiment, the cathode horizontal drive 160 is a linear motor module, and the cathode lifting drive 170 is a cylinder. In another embodiment, the cathode horizontal drive 160 and the cathode lifting drive 170 can also be selected from other devices with the same function according to the actual application conditions.

[0058] In practical applications, to reduce the difference in current path length between different conductive clips 220 and thus ensure the current uniformity of multiple conductive clips 220, two conductive blocks 210 are used. These two conductive blocks 210 are respectively positioned at both ends of the electroplating fixture 200 in the first horizontal direction, and multiple conductive clips 220 are arranged sequentially between the two conductive blocks 210. To achieve accurate detection of the resistance of different conductive clips 220, in this embodiment, two anode probes 120, two fixing brackets 140, and two anode lifting drive components 150 are used. The two anode probes 120 are respectively arranged corresponding to the two conductive blocks 210, and each of the two anode probes 120 is equipped with one fixing bracket 140 and one anode lifting drive component 150.

[0059] When testing the resistance of any conductive clip 220, the conductive block 210 closer to the clip 220 is brought into contact with the corresponding anode probe 120 to conduct electricity, and then the cathode probe 130 is brought into contact with the clip 220 to conduct electricity, thereby achieving resistance testing of the shortest current path for the clip 220. This method is used to test the resistance of all conductive clips 220, reducing the impact of differences in current path length on the accuracy of the test results.

[0060] In summary, the electroplating rack resistance detection device 100 provided in this embodiment can automatically detect the resistance of the electroplating rack 200 on the electroplating production line. It has high detection efficiency and can ensure the reliability of the electroplating rack 200 on the line, thereby improving the electroplating effect of the electroplating production line.

[0061] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
