Abstract
Description
Technical Field
[0001] This application relates to the field of sampling device technology, and in particular to a coating sampler. Background Technology
[0002] Lithium-ion batteries are a type of battery that uses lithium metal or lithium alloys as positive / negative electrode materials and a non-aqueous electrolyte solution. They are widely used in many fields such as electrical appliances and new energy vehicles. The coating process is a crucial step in lithium-ion battery production. Its main purpose is to uniformly coat a well-stirred slurry onto a current collector (such as Al or Cu foil) and then dry the organic solvent in the slurry to form a uniform electrode sheet. Electrode areal density is a key parameter in the coating process, directly affecting battery performance and consistency. Therefore, it is usually necessary to sample and test the electrode areal density during the coating process to ensure the smooth progress of subsequent coating steps. Currently, most technologies use manual samplers for sampling. However, manual samplers have low accuracy, and prolonged use can cause punch wear, affecting accuracy. Furthermore, their low efficiency affects measurement time, thus requiring improvement. Utility Model Content
[0003] To address the problem of easy wear on the punch of a manual sampler, which leads to low sampling accuracy and low measurement efficiency, this application provides a coating sampler.
[0004] The coating sampler provided in this application adopts the following technical solution:
[0005] A coating sampler includes a base, a positioning bracket on the base, a sampling chamber for placing coating material below the positioning bracket, an air source drive unit on the positioning bracket, a punch for cutting and sampling the coating material on the air source drive unit, and a sampling groove on the bottom wall of the sampling chamber located below the punch.
[0006] By adopting the above technical solution, the coating to be cut and sampled is placed in the sampling chamber. The air source drives the punch to descend and cut the coating. The cut sample will fall into the sampling groove, which is convenient for the staff to pick up. The air source drives the punch to cut and sample, which improves the problems of low sampling accuracy and inconvenient cutting of manual samplers, and helps to improve the accuracy of subsequent sampling and testing.
[0007] Optionally, a pressure plate is provided on the top wall of the sampling chamber, the punch passes through the pressure plate, and a power component for driving the pressure plate to rise and fall is provided inside the positioning bracket.
[0008] By adopting the above technical solution, the starting power component drives the clamping plate to descend, thereby pressing the coating in the sampling chamber to ensure the stability of the coating when the punch cuts it, so that the cut sample can be more regular and help improve the subsequent detection accuracy.
[0009] Optionally, the bottom wall of the sampling chamber is provided with a plurality of buffer holes, and an elastic element is provided in the buffer hole. A buffer block is provided at the top of the elastic element, and the elastic element causes the upper end of the buffer block to extend out of the buffer hole.
[0010] By adopting the above technical solution, the elastic element and buffer block can abut and buffer the descending pressure plate to prevent the pressure plate from descending too much, causing the coated sample to be damaged by excessive pressure, destroying its original electrode surface density, and affecting the test results.
[0011] Optionally, a lifting component is provided in the sampling groove, and a receiving block is provided at the top of the lifting component, the shape of which is adapted to the shape of the sampling groove.
[0012] By adopting the above technical solution, the lifting component and the receiving block can temporarily block the sampling groove when the punch cuts and samples the coating, so as to prevent the coating from being driven into the sampling groove during the cutting process, which would cause the cut sample to be damaged, and further improve the cutting accuracy of the coating sampler of this application.
[0013] Optionally, the punch is a ring-shaped cutter.
[0014] By adopting the above technical solution, the ring cutter can cut the coating in a closed loop, which effectively improves the cutting and sampling efficiency of the coating sampler of this application.
[0015] Optionally, the surface of the receiving block is provided with an annular groove for the punch to abut.
[0016] By adopting the above technical solution, an annular groove is opened for the punch to enter, so that the punch can completely penetrate the coating, thereby achieving a complete cutting effect. This prevents the problem of incomplete coating cutting and the problem of some of the cut sample still being attached to the coating, further improving the cutting and sampling efficiency and accuracy of the coating sampler of this application.
[0017] Optionally, an annular block is provided inside the annular groove, and a reset member is provided between the bottom wall of the annular block and the bottom wall of the annular groove.
[0018] By adopting the above technical solution, an annular block and a reset component are set up to facilitate the reset of the punch after cutting, thereby reducing the probability of the punch getting stuck in the annular groove.
[0019] Optionally, the bottom end of the air source drive component is provided with a connecting flange, and the punch is connected to the air source drive component through the connecting flange.
[0020] By adopting the above technical solution and setting a connecting flange, the punch and the air source drive component are detachably connected, which facilitates convenient replacement of the punch when it is damaged, and further improves the efficiency of the coating sampler of this application.
[0021] In summary, this application includes at least one of the following beneficial technical effects:
[0022] 1. Place the coating to be cut and sampled in the sampling chamber. Drive the punch to descend and cut the coating using the air source drive. The cut sample will fall into the sampling groove for easy picking up by the staff. The air source drive to drive the punch to cut and sample improves the problems of low sampling accuracy and inconvenient cutting of manual samplers, and helps to improve the accuracy of subsequent sampling and testing.
[0023] 2. The ring cutter can cut the coating in a closed loop, which effectively improves the cutting and sampling efficiency of the coating sampler of this application. Attached Figure Description

[0027] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.
[0028] This application discloses a coating sampler. (Refer to...) Figure 1 The system includes a base 1, a positioning bracket 2 on the base 1, and a sampling chamber 3 between the positioning bracket 2 and the base 1 for placing the coating to be cut and sampled. The positioning bracket 2 is equipped with a gas source drive 4. In this embodiment, the gas source drive 4 can be a cylinder, whose piston rod passes through the positioning bracket 2. The piston rod end wall of the gas source drive 4 is provided with a connecting flange 17, and a punch 5 is bolted to the connecting flange 17. The punch 5 is a ring cutter to completely cut the coating.
[0029] Reference Figure 1 The top wall of the sampling chamber 3 is provided with a pressure plate 7, and the punch 5 passes through the pressure plate 7. The positioning bracket 2 is provided with a power component 8. In this embodiment, the power component 8 is an electric telescopic rod, and its telescopic end is set in the vertical direction. The telescopic end of the power component 8 is connected to the pressure plate 7 to drive the pressure plate 7 to move up and down, thereby pressing the coating in the sampling chamber 3, so that the coating remains stable when it is cut again, and improving the sampling accuracy. The bottom wall of the sampling chamber 3 is provided with several buffer holes 9, and each buffer hole 9 is provided with an elastic component 10. In this embodiment, the elastic component 10 is a guide rod and a spring. The guide rod is set vertically and its bottom end is inserted into the buffer hole 9 to form a sliding connection with the buffer hole 9. The spring is sleeved on the periphery of the guide rod. The top of the elastic component 10 is provided with a buffer block 11. The spring abuts between the bottom wall of the buffer block 11 and the bottom wall of the buffer hole 9. When the spring is in the extended state, the elastic component 10 pushes the top of the buffer block 11 out of the buffer hole 9.
[0030] Reference Figure 1 and Figure 2 The bottom wall of the sampling chamber 3 is provided with a sampling groove 6, which is located below the punch 5. The diameter of the sampling groove 6 is larger than the diameter of the punch 5. A lifting member 12 is provided in the sampling groove 6. In this embodiment, the lifting member 12 is an electric telescopic rod. The lifting member 12 is vertically arranged, and its movable end is connected to a receiving block 13. The shape of the receiving block 13 is adapted to the shape of the sampling groove 6 so as to temporarily block the sampling groove 6 when the punch 5 cuts and samples the coating, so as to prevent the coating from sliding towards the inside of the sampling groove 6 under the pressure of the punch 5.
[0031] Reference Figure 1 and Figure 2 The receiving block 13 has an annular groove 14 on its surface for the punch 5 to abut, so that the punch 5 can completely penetrate the coating during the cutting process and cut the sample completely. An annular block 15 is provided in the annular groove 14, and several reset members 16 are provided on the bottom wall of the annular block 15. In this embodiment, the reset members 16 are springs. The reset members 16 abut between the bottom wall of the annular block 15 and the bottom wall of the annular groove 14. When the reset members 16 are not under the pressure of the punch 5, the top wall of the annular block 15 is flush with the top wall of the receiving block 13. After the cutting is completed, the lifting member 12 drives the receiving block 13 to descend, thereby completing the automatic collection of the cut coating sample. This allows the staff to directly pick up the disc-shaped sample from the sampling groove 6, further saving the time of the entire cutting and sampling process and improving the overall work efficiency.
[0032] The implementation principle of the coating sampler in this application embodiment is as follows: the coating to be cut and sampled is placed in the sampling chamber 3, and the punch 5 is driven down by the air source drive 4 to cut the coating. The cut sample will fall into the sampling groove 6 for easy picking up by the staff. The cutting and sampling by the punch 5 driven by the air source drive 4 improves the problems of low sampling accuracy and inconvenient cutting of manual samplers, and helps to improve the accuracy of subsequent sampling and detection.
[0033] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
