DETAILED DESCRIPTION

[0020] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.

[0021] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which the utility model belongs.

[0022] like Figures 1 to 4 As shown, a specific embodiment of the utility model provides a photovoltaic cell pin power-on test device, which can avoid the problem of cell rupture and damage caused by the height difference of the pressing structure during the power-on test; specifically, it includes a pressing mechanism and a driving mechanism; the pressing mechanism includes a pressing plate 100, a rotating table 110 is provided in the middle of the upper end of the pressing plate 100, and adjustment tables 120 are provided on both sides of the upper end of the pressing plate 100 corresponding to the rotating table 110, and the lower end of the pressing plate 100 is provided with a power-on copper bus 200 arranged in parallel and at intervals, and the lower end of the power-on copper bus 200 is provided with pin needles 300 arranged at intervals; the driving mechanism includes a driving seat 400, the driving seat 400 is rotatably matched with the rotating table 110, and angle adjusters 500 screwed on both sides of the driving seat 400 are provided to abut against the adjusting table 120, and the driving seat is transmission-connected with an electric cylinder module 600 that can drive the driving seat and the pressing plate 100 to move up and down.

[0023] like Figures 1 to 4 As shown, through the above arrangement, the pressing plate 100 of the pressing mechanism in this embodiment and the driving seat 400 of the driving mechanism are rotationally matched, so that the pressing plate 100 can rotate around the rotating table 110. Before the test operation, the technician can accurately adjust the angle of the pressing plate 100 by rotating the angle adjusters 500 at the front and rear ends of the driving seat to ensure that the pressing plate 100 with the power-on plate installed remains horizontal to avoid height differences. The angle adjuster 500 adopts a differential probe angle adjuster structure to ensure adjustment accuracy. During the test, the electric cylinder module 600 is used to drive the downward pressure for pressing so that the entire surface of the pin needle 300 on the power-on copper bus 200 contacts the photovoltaic cell. Since the pin needle 300 remains horizontal, the problem of cell rupture due to angle problems can be avoided.

[0024] As mentioned above, the drive seat 400 is driven to move up and down by the electric cylinder module 600, so that the pressing plate 100 moves down for pressing. In order to ensure stability during the up and down movement, the present embodiment is provided with a positioning plate 700 above the drive seat, and the upper end of the drive seat is connected with a guide rod 800 that moves through the positioning plate 700; the positioning plate is provided with a linear bearing 900 that slides with the guide rod 800. The stability and pressing accuracy of the up and down movement of the drive seat are ensured by the cooperation of the guide rod 800 and the linear bearing 900, and the linear bearing 900 reduces the friction of the up and down movement of the guide rod 800.

[0025] like Figure 2 As shown, in order to establish a transmission connection between the drive seat and the electric cylinder module 600 , a connection port 410 connected to the piston end of the electric cylinder module 600 is provided at the end of the drive seat in this embodiment.

[0026] As mentioned above, in this embodiment, the driving seat is rotatably matched with the middle part of the pressing plate 100, so that the angle of the pressing plate 100 can be adjusted. In this embodiment, a mounting bearing 1000 rotatably matched with the driving seat is provided on the rotating platform 110. The bearing structure ensures the flexibility and accuracy of the adjustment of the pressing plate 100.

[0027] like Figure 1 As shown, this embodiment also provides an electric cylinder bracket 1500 for installing the entire mechanism, the electric cylinder module 600 is fixed to the upper end of the electric cylinder bracket 1500, and a placement table 1510 for placing photovoltaic cells is fixed below the electric cylinder bracket 1500 corresponding to the energized copper bar. The electric cylinder bracket 1500 can stably install the electric cylinder structure, and the end of the positioning plate 700 can be fixed to the upper end of the electric cylinder bracket 1500 to fix the pressed structure and ensure the stability of the entire structure. When in use, the photovoltaic cells are placed on the placement table 1510 for pressing and powering on test.

[0028] Embodiment 2

[0029] like Figures 1 to 4 As shown, this embodiment further optimizes the pressing structure. Specifically, the lower end of the pressing plate 100 corresponds to the two ends of the power-on copper bus 200 and is provided with connecting rods that movably pass through each power-on copper bus 200.

[0030] 1100, each power-on copper bar 200 is screwed with a pre-tightening screw that can abut against the connecting rod 1100

[0031] 1200. Since each power-on copper busbar 200 is movably matched with the connecting rod 1100, the spacing between adjacent power-on copper busbars 200 is adjustable, and after the adjustment is completed, they are fixed by the pre-tightening screws 1200; in addition, in this embodiment, side plates 1300 arranged along the length of the power-on copper busbar 200 are provided at both ends of the lower end of the pressing plate 100 corresponding to the connecting rod 1100.

[0032] like Figures 1 to 4 As shown, in order to improve the automation of the power-on test device, the present embodiment is provided with a sensor module 1400 at the lower end of the pressing plate 100, which is connected to the electric cylinder module 600 by signal. When the sensor module 1400 detects that the photovoltaic cell is placed on the placement table 1510, the electric cylinder is automatically started to complete the pressing action, which has a high degree of automation.

[0033] like Figures 1 to 4 As shown, when the device is in use, the specific steps are as follows: first, adjust the spacing between adjacent power-on copper busbars 200 according to the specifications of the battery cells to ensure that after the pressing assembly is pressed down, the pin needles 300 can correspond to the main grid line of the battery cell below; after the adjustment is completed, use the pre-tightening screw 1200 to lock it to prevent the power-on copper busbar 200 from moving during the movement of the mechanism; then rotate the angle adjuster 500 to adjust the horizontality of the pressure plate 100 so that its two ends are on the same horizontal plane, so that after pressing down, the head of the pin needle 300 will contact the battery cell with its entire surface to prevent the battery cell from being easily broken when pressed down.

[0034] When the sensor module 1400 detects that there is a battery cell below, the electric cylinder module 600 is triggered to start action, so that the pin needle 300 is pressed down to fit tightly with the main grid of the battery cell, and the force is evenly distributed on the battery cell. During the contact process, the power-on copper bus 200 will be given a pre-set current and voltage value. After the pressurization is completed, the electric cylinder structure drives the pressing mechanism to move vertically upward, thus completing the voltage closing action.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model, and they should all be included in the scope of the claims and specification of the utility model.
