Description

Technical Field

[0001] The utility model relates to the technical field of quality detection of alkali polishing additives, in particular to quality detection equipment for the production of alkali polishing additives for photovoltaic cells. Background Art

[0002] The alkaline polishing process for photovoltaic cells is an important step in the manufacturing process of photovoltaic cells. Its main purpose is to polish the back of the cell with alkaline polishing additives to improve the photoelectric conversion efficiency of the cell. This process uses the chemical corrosion effect of alkaline polishing additives on the surface of the silicon wafer to remove surface impurities and oxide layers, forming a uniform and delicate surface that is conducive to light absorption and conversion.

[0003] Patent publication number CN217820282U discloses a quality inspection device for alkali polishing additives, belonging to the field of alkali polishing additive inspection devices, comprising a base, a detection assembly being provided above the base, and a lead screw drive assembly being provided between the detection assembly and the base for driving the detection assembly to move up and down; a storage platform being fixedly connected to the center of the top surface of the base, and a tilt adjustment assembly being provided inside the storage platform, at least three baffles being fixedly connected to the outer side surface of the storage platform, the tilt adjustment assembly specifically comprising: an adjustment slot provided inside the storage platform, an adjustable support plate being movably connected to the top opening of the adjustment slot, and a shaft being fixedly connected to the middle position inside the adjustable support plate;

[0004] Although the quality inspection device for alkali polishing additives can slightly tilt the measuring cup through the tilt adjustment component to increase the liquid level and prevent the pH test pen from contacting the bottom of the measuring cup and being damaged during subsequent testing, it can only inspect the alkali polishing additive in one measuring cup at a time. When producing large quantities of alkali polishing additives, the inspection rate is slow and cannot meet the inspection requirements. Utility Model Content

The fixing ring 401 is provided with connecting arms 402 fixedly connected to the connecting plate 5 on both sides, the bottom end of the screw 7 is connected to the top bearing of the detection platform 1, the bottom end of the screw 7 is coaxially fixed to the smooth connecting rod 1301 passing through the horizontal plate 102, and the top of the smooth connecting rod 1301 is coaxially fixed to the knob 13. The top surface of the placement seat 2 is downwardly provided with a placement groove 201 for placing the measuring cup 3. In this embodiment, when producing multiple batches of alkali polishing additives, different batches of alkali polishing additives are respectively filled by the measuring cups 3, and then the measuring cups 3 are placed in the placement groove 201. Then, turning the knob 13 will drive the screw 7 to rotate, so that the movable plate 6 drives the connecting plate 5 and the PH detection head 4 to descend, so that the PH detection head 4 enters the liquid surface to detect the alkali polishing additives. The alkali polishing additives in the multiple measuring cups 3 above the detection platform 1 are measured by multiple PH detection heads 4, thereby effectively improving the detection rate of multiple batches of alkali polishing additives.

[0031] Among them, guide rods 8 are provided on both sides of the screw rod 7, and the two ends of the guide rod 8 are fixedly connected to the horizontal plate 102 and the detection platform 1 respectively. The guide rod 8 passes through the movable plate 6 and is slidingly connected to the movable plate 6. In this embodiment, the guide rod 8 guides the movement of the movable plate 6 to ensure the stable movement of the movable plate 6, and the guide rod 8 can also reinforce the horizontal plate 102.

In this embodiment, the horizontal height of the limit block 12 is adjusted by rotating the limit block 12 so that the top surface of the limit block 12 is higher than the bottom surface of the inner wall of the measuring cup 3. Since the bottom surface of the limit column 10 is lower than the bottom surface of the PH detection head 4, the top surface of the limit block 12 is higher than the bottom surface of the inner wall of the measuring cup 3.

In this embodiment, the anti-slip ridges 1302 increase the friction of the knob 13, making the knob 13 more convenient to rotate.

[0035] As can be understood, firstly, the present invention uses multiple pH test heads 4 to measure the alkali polishing additives in multiple measuring cups 3, effectively improving the detection rate of multiple batches of alkali polishing additives. Secondly, by rotating the limit block 12 to adjust the horizontal height of the limit block 12, the top surface of the limit block 12 is higher than the inner wall bottom surface of the measuring cup 3. During the descent of the pH test head 4, the limit block 12 contacts the limit post 10 to block the movable plate 6, thereby preventing the pH test head 4 from colliding with the inner wall bottom surface of the measuring cup 3.

[0036] A specific application of this embodiment is: when producing multiple batches of alkali polishing additives, different batches of alkali polishing additives are respectively contained in the measuring cup 3, and then the measuring cup 3 is placed in the placement groove 201, and then the knob 13 is turned to drive the screw 7 to rotate, so that the movable plate 6 drives the connecting plate 5 and the pH detection head 4 to descend, so that the pH detection head 4 enters the liquid surface to detect the alkali polishing additives, and the alkali polishing additives in the multiple measuring cups 3 above the detection table 1 are measured respectively by multiple pH detection heads 4, thereby effectively improving the detection rate of multiple batches of alkali polishing additives, and the horizontal height of the limit block 12 is adjusted by rotating the limit block 12 so that the top surface of the limit block 12 is higher than the bottom surface of the inner wall of the measuring cup 3. Since the bottom surface of the limit column 10 is lower than the bottom surface of the pH detection head 4, the top surface of the limit block 12 is higher than the bottom surface of the inner wall of the measuring cup 3. During the descending process of the pH detection head 4, the limit block 12 contacts the limit column 10 to block the movable plate 6, which can prevent the pH detection head 4 from colliding with the bottom surface of the inner wall of the measuring cup 3.
