Description

Technical Field

[0001] The utility model belongs to the technical field of lamps, and in particular relates to auxiliary equipment for testing the limit compaction of lithium battery materials. Background Art

[0002] Compacted density refers to the mass or density of a material per unit volume after it is subjected to a certain pressure. Under the same volume, the greater the compacted density of the pole piece, the higher the energy density. In the field of batteries, the compacted density of the battery pole piece directly affects its energy density, charge and discharge performance, and the cycle life of the battery. Although increasing the volume energy density of the battery can increase the sustainable use time of electronic devices, if the compacted density of the pole piece is too large, the pole piece will break during the rolling or winding process, affecting the normal production of the battery.

[0003] The current common method for testing the compaction density of battery pole pieces is to cut the pole piece into a circle, then fold it in half manually to observe whether the crease is light-transmissive. When testing the compaction density of battery pole pieces, an ordinary desk lamp is currently used, and the desk lamp is placed below the person's field of vision so that the folded crease can be observed through the light to see whether it is light-transmissive. For testers, looking at the light for a long time will cause eye discomfort, so the lamp will be turned off when it is not necessary to observe the crease. However, the switch of conventional lamps needs to be operated by hand, and the tester needs to free up one hand to operate the switch, which affects the continuity of the pole piece extreme compaction test action performed by the hand and reduces the test efficiency.

[0004] Therefore, it is necessary to provide an improved technical solution to address the above-mentioned deficiencies in the prior art. Utility Model Content

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field belong to the protection scope of the present invention.

[0029] In the description of the present invention, the terms "longitudinal", "lateral", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and do not require that the present invention must be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention. The terms "connected" and "connection" used in the present invention should be understood in a broad sense. For example, they can be fixed connections or detachable connections; they can be directly connected or indirectly connected through intermediate components. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0030] The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict.

[0031] like Figures 1 to 6As shown, an auxiliary device for testing the ultimate compaction of lithium battery materials comprises a lamp body 1, a foot switch 4 connected to the lamp body 1 via a power line 3, and a fixing clamp; the fixing clamp comprises a clamping body 5 for fixing on a table board and an upper fixing part 11 arranged outside the clamping body 5, and the power line 3 is clamped and fixed by the upper fixing part 11;

[0032] The switch mode of the lamp of the present invention is a convenient foot switch, which allows the user to control the switch of the lamp without stopping the hand operation. The lamp used in the battery electrode compaction density test generally adopts a wired power supply mode, and the lamp body 1 is just placed directly on the desktop, which is convenient for the tester to adjust the position of the lamp body 1 at any time according to personal habits. However, since the power line 3 itself has weight, the lamp is often offset due to the force of the falling wire when in use. Therefore, the lamp controlled by the foot switch designed according to the actual use needs of the present invention is additionally provided with a fixing clamp, which can fix the power line 3. In this way, the length of the power line 3 between the lamp body 1 and the fixing clamp is shortened, and this part of the power line 3 will not fall due to the weight of the lower part of the power line 3, so that the force of the falling part of the power line 3 will hardly cause the position of the lamp body 1 to be pulled and offset, so that the lamp body 1 can be kept in the position where the tester places it for a long time.

[0033] like Figure 1 to Figure 2 As shown, the lamp body 1 has no separately provided lamp base and is directly placed on the desktop for use, which reduces the structural cost of the lamp body 1 and allows the position of the lamp body 1 to be flexibly adjusted according to the use of the workbench; the side view of the lamp body 1 is a triangle or a trapezoid, and the light irradiation direction of the lamp body 1 is obliquely upward; a brightness adjustment knob 2 is provided on the lamp body 1. The lamp body 1 is also provided with a power cord and a plug (not shown in the figure), and has a socket at the edge of the workbench. The plug is directly inserted into the socket, and the power cord can be directly on the desktop.

[0034] like Figures 1 to 6As shown, the clamping body 5 includes a U-shaped frame, and the U-shaped frame includes an upper horizontal plate, a lower horizontal plate and a vertical plate fixed between the upper horizontal plate and the lower horizontal plate. The lower horizontal plate is provided with an adjusting rod 8, and a top plate 6 is fixed on the top of the adjusting rod 8. The distance between the top plate 6 and the upper horizontal plate can be adjusted and locked. Specifically, the adjusting rod 8 is threadedly connected with the lower horizontal plate, and the fixing clamp and the power supply line 3 can be clamped at a position on the workbench as needed; the lower part of the adjusting rod 8 is fixed with a hand-tightening part 9 that is convenient for hand-tightening; when in use, the clamping workbench of the fixing clamp is adjusted by screwing the adjusting rod 8; if it is needed to be used in other places, the fixing clamp can be separated from the power supply line 3 first, and then the lamp body 1 can be placed at the desired position, and then the power supply line 3 can be fixed on the fixing clamp; the surface of the top plate 6 is provided with a cushion layer, which is slightly elastic and can be made of conventional materials such as silicone, latex, rubber or polyurethane. In practice, the clamping body 5 can be a commercially available G-shaped woodworking clamp or a drawer panel woodworking clamp, and then the fixing clamp of the utility model can be manufactured by self-modification on the basis of the commercially available G-shaped woodworking clamp or the drawer panel woodworking clamp.

[0035] The upper wire fixing component 11 is arranged on the outer side of the vertical plate of the fixing clamp or on the upper surface of the upper horizontal plate; the upper wire fixing component 11 can be a spring piece that can compress the power line 3, a commercially available product that can fix electric wires, or a hand-tightened bolt that is threadedly connected to the fixing clamp to compress the power line 3; the upper fixing part 7 is installed by welding, gluing, threading, punching, etc. according to the type of the upper fixing part 7. Figure 3 , Figure 5 The upper wire fixing component 11 in the form of a spring sheet is a wire pressing piece. The first end of the wire pressing piece is welded or glued to the upper surface of the fixing clamp, and the other end of the wire pressing piece is first bent upward, then bent horizontally downward, and finally bent upward to form a small opening for the power supply line 3 to enter.

[0036] In an optional embodiment, when the power cord 3 is long, after the upper portion of the power cord 3 is clamped and fixed by the upper fixing portion 7, the lower portion of the power cord 3 will fall to the ground. During the test, the tester may step on the power cord 3 when stepping on the foot switch 4 or moving his legs, which may cause wear of the power cord 3 in the long run. In addition, the power cord 3 may be hooked during the back-and-forth movement of the legs, causing the power cord 3 to be pulled. In order to reduce possible damage to the power cord 3, in this embodiment, a lower wire fixing component 13 is fixed to the lower portion of the outer side of the vertical plate; the power cord 3 can be clamped and fixed by the lower wire fixing component 13, and a wire management component for storing the power cord 3 is fixed to the outer side of the vertical plate. When in use, excess power cords 3 can be accommodated in the wire management component to prevent the power cord 3 from falling to the ground.

[0037] The cable management components can be of various types. In one embodiment, Figure 5As shown, the wire management component is a winding post 15, which is vertically mounted on the outer side of the vertical plate through a base, and the power line 3 can be wound and placed on the winding post 15. One or more winding posts 15 can be set, such as two winding posts 15 are set at intervals, or three winding posts 15 are arranged in a triangle. In another embodiment, Figures 1 to 4 As shown, the wire management component includes a wire management column 10, and a plurality of the wire management columns 10 are perpendicular to the outer side of the vertical plate and are arranged at intervals. The size of the free end of the wire management column 10 is increased to prevent the power supply line 3 wound thereon from falling off from the free end; the wire management column 10 can be bolted, etc., and the bolt can be welded and fixed or a hole can be punched on the vertical plate for threaded installation of the bolt; optionally, the wire management component also includes a wire blocking component 12 that can be wound around two relatively wire management columns 10; when the number of the wire management columns 10 is greater than three, such as Figure 2 As shown, the power supply line 3 can be wound around the outer ring of the wire management pole 10, or can be wound into a ring coil by hand and then inserted into the area surrounded by the wire management pole 10, and then clamped between two wire management poles 10 with a wire blocking component 12 to press and fix the power supply coil; the wire blocking component 12 can be an elastic ring or rope such as a rubber band, iron wire, etc. In another embodiment, as Figure 6 , Figure 7 As shown, the wire management component includes a winding drum 14 vertically fixed on the outer side of the vertical plate, and an outward-expanding baffle is fixed at the outer edge of the circumference of the winding drum 14. The baffle is provided with a wire clamping notch as an upper wire fixing component 11, and a small clip can also be used to directly clamp the position where the power supply line 3 needs to be fixed on the clamping body 5 or the baffle; the winding drum 14 can be made of a cut tube, which can be a metal tube or a plastic tube. After the tube is cut, a longitudinal slit is made from the edge of one end, and then it is bent outward and shaped to serve as a baffle.

[0038] When in use, clamp the fixing clip in an appropriate working area, such as the edge of a workbench; then, place the lamp body 1 in the operating area of ​​the workbench and adjust the angle to facilitate lighting (the brightness of the lamp can be adjusted with the brightness adjustment knob 2 according to the needs of your own operating scene); adjust the position of the upper part of the power supply line 3 clamped and fixed by the upper wire fixing component 11; when testing, fold the sample disc to be observed in half, and control the foot switch 4 with the foot at the same time, so as to operate the switch of the lamp at the same time without stopping the hand work; after the observation is completed, put down the sample disc, and control the foot switch 4 with the foot at the same time to turn off the lighting, and then carry out other subsequent work.

[0039] The utility model is small in size, light in weight, has good operability and mobility, and can be carried around; it has a simple structure, is easy to prepare, and is cheap; it can adapt to the lighting needs of other narrow working environments except for the embodiment or other working scenes that require frequent switching of lamps, and has a wide range of applications.
