[0002] Competition in the photovoltaic industry is becoming increasingly fierce, and process optimization in cell manufacturing is a key factor in improving conversion efficiency. Process optimization requires the detection of internal defects in the production process, and PL (photoluminescence) is one of the most effective ways to detect internal defects. The photovoltaic industry has a wide range of needs for PL testing equipment, but in some situations where random sampling is required, there is currently no suitable and powerful PL testing equipment available.

[0003] Utility model patent CN214150439U discloses a PL (Plastic Photonics) inspection instrument, including a housing, camera, upper light source group, lower light source group, inspection platform, multiple sets of transparent fine lines, image transmission control lines, and an integrated image control and processing unit. As shown in the aforementioned utility model, existing PL inspection instruments support silicon wafers using transparent fine lines, avoiding potential secondary contamination of the silicon wafers during the inspection process. Furthermore, the use of transparent fine lines makes it possible to have PL excitation light sources on both the top and bottom of the silicon wafer, achieving optimal PL inspection results. However, existing inspection equipment cannot efficiently and accurately complete the entire process from product loading and testing to receiving, leading to extended production cycles, increased costs, and deficiencies in product quality control.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-2 This utility model provides two technical solutions:

[0023] First implementation: A PL product adjustment and testing machine, including a blister box loading and unloading machine 1 and a testing host 2. The blister box loading and unloading machine 1 and the testing host 2 are of separate structure. The blister box loading and unloading machine 1 and the testing host 2 are equipped with protective covers and cabinet doors on their outer sides. The equipment operates on a voltage of 220V / 380V, an air source pressure of 0.4-0.6MPa, and a negative pressure of -100kPa.

[0024] Specifically, the blister box loading and unloading machine 1 is equipped with a blister box loading area 11, a test pick-and-place position 12, and a receiving area 13. The loading area 11 is used to place stacked blister boxes. The blister boxes are positioned by internal positioning and contouring. The loading mechanism of the blister box loading area 11 can separate the blister boxes and transport them to the test pick-and-place position 12.

[0025] Specifically, the test host 2 includes test area A 21, test area B 22 and NG area 23. Test area A 21 and test area B 22 are equipped with multiple bottom test probes 24. Test area A 21 and test area B 22 adopt independent control systems, which can test different products simultaneously. The blister packs on test area A 21 and test area B 22 and the NG tray on NG area 23 are driven by the linear module below and move synchronously with the robot arm 31 to test the products.

[0026] More specifically, receiving area 13 is used to receive tested products. Qualified products are placed back into the blister pack and stacked in receiving area 13, while unqualified products are placed in NG area 23.

[0027] The second implementation differs from the first implementation in that the test host 2 also includes a linear guide rail 3, which is mounted on the test host 2 and used to grab products and move them to test area A 21 and test area B 22 via a robotic arm 31. A barcode scanner 32 is provided on one side of the robotic arm 31, and a pressing component 33 and an current needle 34 are provided on the robotic arm 31. The pressing component 33 and the current needle 34 work together with the bottom test probe 24 to test the products. The suction nozzle of the robotic arm 31 is a customizable contouring suction nozzle, which is made of elastic material with anti-slip texture on the surface, and the suction force of the suction nozzle can be adjusted according to the weight and shape of the product.

[0028] The working process of this device:

[0029] Equipment Installation and Commissioning: The supplier will send technical experts to the buyer's site for equipment installation and commissioning. First, based on the production site layout, the blister packer 1 and the testing main unit 2 will be installed in a separate configuration, ensuring accurate connections between them. Then, a 220V / 380V power supply will be connected, the air pressure adjusted to 0.4-0.6MPa, and the negative pressure adjusted to -100kPa. The operation of each component will be checked to ensure that all parts of the equipment can start and operate normally.

[0030] Loading operation: Manually place the stacked blister packs into the loading area 11. The loading mechanism, according to a preset program, dispenses one tray of products at a time, placing it into the test pick-and-place position 12. The buffer function of the loading machine ensures that replenishing blister packs does not affect the normal operation of the equipment. The internal positioning and contouring device accurately positions the blister packs, and the robotic arm 31 on the linear guide rail 3 accurately picks up 6 products based on the positioning information, ready for testing.

[0031] Testing Process: The six products picked up are first placed in Test Area A 21 for barcode scanning. After scanning, testing is performed. During testing, the current probe 34, the pressure assembly 33, and the bottom test probe 24 work together to detect various performance characteristics of the products. After testing in Test Area A 21 is completed, the linear robot 31 returns the products to the blister pack, and simultaneously picks up another six products and places them in Test Area A 21 for the next round of testing. At the same time, another group of six products is placed in Test Area B 22 for the same barcode scanning and testing operations. Testing in Test Areas A 21 and B 22 is repeated cyclically to improve testing efficiency.

[0032] Receiving operation: After testing, qualified products are returned to the blister pack by the robotic arm 31, and the blister pack is transported to the receiving area 13 for stacking and traying; unqualified products are placed in the NG area 23. When the NG area 23 is full of blister packs, the equipment issues an alarm signal to prompt manual removal. The buffer function of the receiving area 13 can temporarily store multiple trays of blister packs for convenient unified processing.

[0033] Equipment Maintenance and Upgrades: During equipment operation, if general malfunctions occur, customers can troubleshoot themselves using the fault diagnosis module's prompts. The supplier provides free software upgrades periodically, and users can choose whether to upgrade based on their actual needs. During the warranty period, the supplier provides technical consultation, maintenance, and technical support at any time; after the warranty period, the supplier continues to provide extensive and preferential technical support, technical consultation, and spare parts supply, with costs determined through negotiation between both parties. Simultaneously, the supplier provides free system-wide technical training to the customer's technical, operational, and maintenance personnel to ensure that users are proficient in operating and maintaining the equipment. Furthermore, any content not described in detail in this manual is considered prior art known to those skilled in the art, and the model parameters of each electrical component are not specifically limited; conventional equipment can be used.
