Description

Technical Field

[0001] The present application relates to the field of battery cell testing devices, and more specifically, to a battery cell testing tray. Background Art

[0002] Solar cells are divided into crystalline silicon and amorphous silicon. Crystalline silicon cells can be further divided into monocrystalline cells and polycrystalline cells. The efficiency of monocrystalline silicon is also different from that of polycrystalline silicon. In the production process of solar cells, sometimes in order to conduct comparative tests to find the solar cells with the best power generation efficiency and the lowest production cost, we need to use test trays to conduct comparative tests on solar cells.

[0003] However, some existing test trays have fixed specifications. When solar cells of different sizes are tested, workers need to replace the corresponding test trays to test them one by one, and then record the data for comparison, which reduces the efficiency of solar cell testing. Therefore, to solve the above problem, we proposed a solar cell test tray. Utility Model Content

[0004] In order to solve the above problems, the present application provides a battery cell test tray, which adopts the following technical solutions:

[0005] A battery cell test tray comprises a tray body, wherein the four corners of the bottom end of the tray body are fixedly installed with supporting feet, pillars are fixedly installed on both sides of the tray body, and the opposite ends of the two pillars pass through the tray body, movable grooves are opened on the opposite sides of the two pillars, and a limit assembly is provided between the two pillars, a first cylinder is fixedly installed on the other two sides of the tray body, and the two first cylinder piston shafts slide through the tray body, the ends of the two first cylinder piston shafts are fixedly installed with splints, telescopic rods are fixedly installed on both sides of the splints, and the ends of the two telescopic rods are provided with test assemblies, mounting plates are fixedly installed on the tops of the two splints, and pressing assemblies are provided under the two mounting plates, and an ejection assembly is provided on the inner wall of the bottom end of the tray body.

[0006] By adopting the above technical solution, when the device is used, the staff places the battery cell in the tray body, and performs preliminary positioning and fixing of the battery cell through the limiting component. Subsequently, the first cylinder drives the same group of clamps to move toward the battery cell. The cooperation of the two clamps further clamps and fixes the battery cell, and the cooperation of the first cylinder and the clamp can correct the position of the battery cell inside the tray body. The cooperation of the limiting component, the first cylinder and the clamp makes it easier for the tray body to clamp and fix battery cells of different sizes, thereby facilitating the tray body to fix battery cells of different sizes. The battery cells of different sizes are tested. When the battery cells are positioned, the battery cells are tested by the test assembly, and the position of the test assembly can be adjusted by telescoping, which is convenient for the equipment to test battery cells of different sizes. When the battery cell test is completed, the battery cell is ejected from the tray body through the positioning assembly to achieve the effect of removing the material, which is convenient for the staff to take the material later. When the battery cell is raised, the battery cell is installed by pressing the assembly, which helps to avoid the battery cell being displaced or even falling due to the elastic force of the limiting assembly when it is ejected from the clamping assembly, thereby achieving the effect of protecting the battery cell.

[0007] Furthermore, the limiting assembly includes a support rod slidably installed in the movable groove, a fixed plate is fixedly installed on the opposite side of the two support rods, and a rubber pad is fixedly installed on the opposite side of the two fixed plates, and a third spring is fixedly connected between the opposite ends of the two support rods and the inner wall of the opposite side of the movable groove in the same group.

[0008] By adopting the above technical solution, when the staff places the battery cells inside the tray body, the two sides of the battery cells push the fixed plates, and the fixed plates push the support rods of the same group to slide in the movable groove, and the support rods push the third springs of the same group to contract. When the battery cells are inside the tray body, the support rods move toward the outside of the movable groove under the elastic force of the third springs of the same group, and the support rods push the fixed plates to contact the opposite side of the battery cells, which can play a role in restricting and fixing the battery cells.

[0009] Furthermore, two symmetrically distributed limiting blocks are fixedly mounted on the side walls at opposite ends of the two support rods, and limiting grooves matching the limiting blocks on the same side are formed on the inner walls of the two movable grooves.

[0010] By adopting the above technical solution, when the support rod slides in the movable groove, the support rod slides in the same group of limit grooves with the limit block. The cooperation between the limit block and the limit groove helps to prevent the support rod from leaving the movable groove and helps to maintain the stability of the support rod sliding.

[0011] Furthermore, the test assembly includes a mounting block fixedly mounted on the end of the telescopic rod, the side walls of the mounting block are provided with two symmetrically distributed mounting holes, and mounting columns are slidably installed in the mounting holes, the side walls of the mounting columns are sleeved with second springs, and one end of the mounting columns is provided with probes, the side walls of the mounting columns close to the probes in the same group are fixedly sleeved with a retaining ring, and the end of the mounting columns away from the probes in the same group is fixedly installed with a stop block.

[0012] By adopting the above technical solution, the mounting block is driven by the telescopic rod to move with the probe, so as to achieve the effect of adjusting the probe position, which is convenient for the equipment to test battery cells of different sizes. After the battery cell is placed, the first cylinder drives the clamping plate, the mounting block and the probe to move synchronously toward the battery cell. The battery cell is clamped and fixed by the two clamping plates, and the probe is brought into contact with the battery cell, which can play the role of detecting the battery cell. When the probe is in contact with the battery cell, the probe pushes the mounting column of the same group to slide in the mounting hole, and the second spring of the same group is contracted, which can play a buffering role, helping to avoid damage caused by excessive squeezing force when the probe contacts the battery cell, and helping to avoid damage to the battery cell.

[0013] Furthermore, two symmetrically distributed stabilizing blocks are fixedly mounted on the inner wall of the mounting hole, and a stabilizing groove matching the stabilizing block on the same side is formed on the side wall of the mounting column.

[0014] By adopting the above technical solution, a stabilizing block is provided inside the mounting hole, and a stabilizing groove matching the stabilizing block is provided on the side wall of the mounting column. When the mounting column slides in the mounting hole, the stabilizing block slides in the stabilizing groove on the same side. The cooperation between the stabilizing block and the stabilizing groove is conducive to maintaining the stability of the mounting column moving with the probe.

[0015] Furthermore, the pressing assembly includes a pressing plate arranged under the mounting plate, and two symmetrically distributed lifting rods are slidably installed on the top of the two mounting plates, and a disc is fixedly installed on the top of the lifting rods. The bottom ends of the two lifting rods in the same group slide through the mounting plates in the same group, and the side walls of the lower sections of the lifting rods are each provided with a first spring, and the bottom ends of the two lifting rods in the same group are fixedly connected to the top of the pressing plate in the same group.

[0016] By adopting the above technical solution, when the battery cell is located inside the tray body and rises, the top of the battery cell contacts the bottom of the pressing plate. When the battery cell continues to rise, the battery cell pushes the pressing plate to rise synchronously, and the pressing plate pushes the lifting rod of the same group to rise, and causes the first spring of the same group to contract. Then, the pressing plate moves downward under the elastic force of the first spring, so that the pressing plate is in close contact with the battery cell, which can play the role of pressing and fixing the battery cell, helping to prevent the battery cell from deflecting or even falling when it rises and separates from the fixing plate, thereby achieving the role of protecting the battery cell.

[0017] Furthermore, two symmetrically distributed sliding blocks are fixedly mounted on the side of the pressing plate close to the same group of clamping plates, and a sliding groove matching the sliding blocks is provided on the side of the clamping plate close to the same group of pressing plates.

[0018] By adopting the above technical solution, when the pressing plate is raised or lowered, the pressing plate slides synchronously with the slider in the sliding groove opened on the inner side of the fixed plate of the same group. The cooperation between the slider and the sliding groove is conducive to maintaining the stability of the pressing plate's lifting and lowering.

[0019] Furthermore, the ejection assembly includes an ejection plate arranged in the pallet body, a second cylinder is fixedly installed on the bottom end of the pallet body, and the piston shaft of the second cylinder slides through the pallet body, the second cylinder piston shaft is fixedly connected to the bottom end of the ejection plate, and the inner wall of the bottom end of the pallet body is provided with a storage groove matching the ejection plate.

[0020] By adopting the above technical solution, when the battery cell test is completed, the ejector plate is driven to rise by the second cylinder, and the battery cell is ejected from the tray body by the ejector plate, which can play the role of removing the material and is convenient for the staff to take it. In addition, the inner wall of the bottom end of the tray body is provided with a storage groove that matches the ejector plate, which plays the role of storing the ejector plate without affecting the placement of the battery cell in the tray body.

[0021] In summary, this application has the following beneficial technical effects:

[0022] (1) In the present application, the setting of the limiting assembly plays a role in limiting the positioning of the battery cell, and the cooperation of the first cylinder and the clamp 4 plays a role in further positioning and fixing the battery cell, which facilitates the subsequent testing of the equipment through the test assembly, and the cooperation of the limiting assembly, the first cylinder and the clamp makes it convenient for the equipment to test battery cells of different sizes, which is beneficial to improving the testing efficiency of the equipment.
