Description

Technical Field

[0001] The present invention relates to the technical field of tensile and compressive testing, and particularly to a battery cell performance testing machine device and its method. Background Art

[0002] A battery cell refers to a device that serves as a container and provides protection in a battery. It must be resistant to sulfuric acid corrosion. In addition, it must also meet some special requirements during use, such as strength, vibration resistance, impact resistance, and resistance to high and low temperatures. Battery cells are divided into short and tall types. The short-type structure has less obvious electrolyte stratification phenomenon, and its capacity characteristics are superior to those of the tall-type battery structure. In addition, in terms of the oxygen recombination effect at the negative electrode inside the battery, the short-type structure has better battery performance than the tall-type structure.

[0003] The existing battery cell performance testing devices have the following problems: 1. Most of the performance testing devices on the market currently use at most two testing means to detect and process the compressive resistance, tensile resistance, or bending resistance of the battery cell; 2. The existing clamping of the battery cell is all carried out by a pressing member to limit and fix it. However, when detecting the torsional resistance of the battery cell, the battery cell during the torsional process is very likely to fall off the clamping device due to excessive torsional force, thus affecting the accuracy of subsequent tests.

[0015] Preferably, a pressure-receiving plug rod is extrusion-fitted on the outer side of the first double-headed plate. A sleeve is slidably fitted on the outer side of the pressure-receiving plug rod. The sleeve is fixedly connected to the outer side of the double circular plate. A transverse groove is formed at the top of the sleeve. A limiting strip is slidably fitted inside the transverse groove.

One end of the extrusion rod away from the second magnetic block is extrusion-fitted with a clamping piece.

[0017] A test method for a battery slot performance testing machine includes the following steps:

[0018] Step 1: By inserting the slot part into the top slot formed in the top of the double circular plate, then rotating the thrust handle downward, the first extension shaft connected to its central part will deflect counterclockwise. At the same time, the first double-headed plate fixedly connected to the outer side of the first extension shaft will deflect counterclockwise accordingly and extrude the pressure-receiving plug rod. The inner end of the first extension shaft is connected to the central shaft, and the other end of the central shaft is connected to the second extension shaft, and the outer side of the second extension shaft is connected to the second double-headed plate. Therefore, the second double-headed plate will deflect counterclockwise accordingly and extrude the pressure-receiving plug rod on the other side of the double circular plate. The first double-headed plate extrudes the pressure-receiving plug rod on the same side with the bottom of one of its heads, while the second double-headed plate extrudes the pressure-receiving plug rod on the same side with the top of one of its heads;

[0019] Step 2: The pressure-receiving plug rod extruded by the first double-headed plate will extend into the inside of the sleeve. The sleeve is communicated with the tubular groove and the spline groove formed inside the double circular plate, and the sleeve and both grooves are filled with gas. Therefore, as the pressure-receiving plug rod extends into the inside of the sleeve, the gas inside it will be compressed and finally enter the inside of the spline groove. However, an extrusion rod is slidably fitted inside the spline groove, and the inner end of the extrusion rod is connected to the second magnetic block, and the inside of the spline groove is connected to the first magnetic block through the inner frame body. There is an attracting relationship between the two magnetic blocks. Therefore, as the gas is compressed, the extrusion rod will drive the second magnetic block away from the first magnetic block and extend outward until it extrudes the clamping piece. Finally, the clamping piece will move towards the central part of the top slot and realize the clamping of the slot part;

[0020] Step three: by deflecting the thrust handle counterclockwise downward, the triangle plate that was originally limited by the top extrusion will move toward the direction of the double circular plate under the compression force of the reset spring, wherein the triangle plate is connected to the reset spring through a compensation block, and the surface of the compensation block is fixedly connected with an insertion rod, so under the compression force of the reset spring, the insertion rod will pass through the surface of the clamping plate and the slot part in turn to achieve the reinforcement and limiting treatment of the slot part. When the bottom of the slot part is clamped, start the motor, so that the screw connected to its output end through the coupling will rotate, and the slider connected to the screw thread will move the center table upward until the top of the slot part contacts another tension and compression mechanism installed at the bottom of the middle support plate, and the top of the slot part is clamped by the same means. Then, by reversing the motor, the center table moves downward to perform a tensile test on the slot part. Similarly, by rotating the motor forward, the center table moves upward to perform a pressure test on the slot part.

[0021] Step 4: In addition, the electric push rod can be started, so that the plate connected to the telescopic end will move forward with the rack, and the other side of the rack is meshed with the gear, and the gear is fixedly connected to the outside of the round seat, so the round seat will rotate, and the top of the round seat is a socket joint, that is, the teeth are fitted, so the socket joint will carry the double circular plate, and the bottom of the slot will rotate together to test the torsion force of the slot itself;

[0022] Step 5: Manually push the plug strip to the right, causing it to move to the right along the inside of the hollow plate. The other end of the plug strip is sleeved on the transfer flower rod, where the plug strip and the transfer flower rod are meshed and connected. Therefore, the plug strip will drive the transfer flower rod to deflect counterclockwise, and then the fixed strip fixedly connected to the outside of the transfer flower rod will deflect counterclockwise with the transfer flower rod as the center, so as to realize the tangential force test on the surface of the groove.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. The extrusion rod moves the No. 2 magnetic block away from the No. 1 magnetic block and extends outward until the clamping piece is squeezed. Finally, the clamping piece moves toward the center of the top groove, thereby completely clamping both sides of the groove.

[0025] 2. The insertion rod will sequentially pass through the surfaces of the clamping piece and the slot part, thereby preventing the slot part from falling off during the torsion test, resulting in test failure, because the torsion force is greater than the clamping force.

[0026] 3. By reversing the motor, the central table moves downward, thus playing a role in detecting the tensile force of the groove part. Similarly, by rotating the motor forward, the central table moves upward, thus playing a role in detecting the pressure of the groove part.

[0027] 4. By rotating the bottom of the groove part while keeping the top of the groove part stationary, it plays a role in detecting the torsional force of the groove part itself. In addition, when performing a pressure test or a tensile test on the groove part, an additional torsional force can be applied to perform multiple test treatments on the groove part itself.

[0028] 5. The fixed strip fixedly connected to the outer side of the transfer flower rod will deflect counterclockwise with the transfer flower rod as the center, thus playing a role in detecting the transverse shear force of the central part of the groove part. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] Tensile and compressive mechanism 10, which is used to perform tensile and pressure test treatments on a vertically-shaped battery slot;

[0047]

[0048] A base 1 is fixedly installed at the bottom of the bending mechanism 9. A casing 2 is fixedly connected to the top of the base 1. A support column 3 is fixedly connected to the top of the casing 2. A motor 4 is fixedly installed at the bottom of the inner cavity of the casing 2. The output end of the motor 4 is connected to a lead screw 5 through a coupling. Both ends of the lead screw 5 are installed inside the support column 3 through bearings. A slider 6 is threadedly connected to the outside of the lead screw 5. Both the upper and lower ends of the slider 6 are fixedly connected to resilient laminations 7. One end of the resilient lamination 7 away from the slider 6 is fixedly connected to the inside of the support column 3. A rubber lens 8 is slidably fitted to the outside of the support column 3. The rubber lens 8 is transparent and facilitates observation and processing by the operator. After the bottom of the groove part 111 is clamped, the motor 4 is started, causing the lead screw 5 connected to its output end through the coupling to rotate. The slider 6 threadedly connected to the lead screw 5 will drive the center table 101 to move upward until the top of the groove part 111 contacts another tensile and compressive mechanism 10 installed at the bottom of the middle support plate 91, and the top of the groove part 111 is clamped by the same means. Subsequently, by reversing the motor 4, the center table 101 moves downward, thereby playing a role in detecting the tensile test of the groove part 111. Similarly, by rotating the motor 4 forward, the center table 101 moves upward, thereby playing a role in detecting the pressure test of the groove part 111.The bending mechanism 9 includes a middle support plate 91, both ends of the middle support plate 91 are fixedly connected to the support column 3, a bending rod 92 is fixedly connected to the top of the middle support plate 91, one end of the bending rod 92 away from the middle support plate 91 is fixedly connected to a limiting platform 93, the bottom of the limiting platform 93 is fixedly connected to an L-shaped plate frame 94, the bottom of the inner side of the L-shaped plate frame 94 is rotatably connected to a transfer rod 95, the top of the transfer rod 95 is rotatably connected to the limiting platform 93, and the outer side of the transfer rod 95 is fixedly connected to a fixing bar 9 6. The outer side of the fixing strip 96 is fixedly connected with a balancing strip 97, the outer side of the transfer flower rod 95 is slidably adapted with a plug-in strip 98, the upper and lower ends of the plug-in strip 98 are slidably adapted with a hollow plate 90, the top of the hollow plate 90 is fixedly connected with a connecting block 901, the end of the hollow plate 90 away from the transfer flower rod 95 is fixedly connected with an arc strip 902, the side of the arc strip 902 away from the hollow plate 90 is slidably adapted with a sliding head 99, and the sliding head 99 is symmetrically connected to the upper and lower ends of the plug-in strip 98. By manually pushing the plug-in strip 98 to the right, the plug-in strip 98 will move to the right along the inside of the hollow plate 90. However, the other end of the plug-in strip 98 is sleeved on the transfer flower rod 95, wherein the plug-in strip 98 and the transfer flower rod 95 are meshingly connected. Therefore, the plug-in strip 98 will drive the transfer flower rod 95 to deflect counterclockwise, and then the fixed strip 96 fixedly connected to the outer side of the transfer flower rod 95 will deflect counterclockwise with the transfer flower rod 95 as the center, thereby playing a role in performing a transverse shear force test on the central part of the groove 111.

[0049] like Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 and Figure 14As shown in the figure, the tension and compression mechanism 10 includes a central platform 101. Both ends of the central platform 101 are fixedly connected to the slider 6. The bottom of the central platform 101 is fixedly connected to the connecting block 901. A circular seat 102 is rotatably installed on the top of the central platform 101. A gear 103 is fixedly connected to the outside of the circular seat 102. A rack 104 is meshed and driven on the outside of the gear 103. A sticker plate 105 is fixedly connected to the side of the rack 104 away from the gear 103. An electric push rod 106 is fixedly connected to the outside of the sticker plate 105. One end of the electric push rod 106 away from the sticker plate 105 is fixedly connected to a rod seat 107. The rod seat 107 is fixedly connected to the top of the central platform 101. A socket joint 108 is fitted and installed on the top of the circular seat 102. A double circular plate 109 is fixedly connected to the top of the socket joint 108. A top groove 110 is opened on the top of the double circular plate 109. A groove part 111 is arranged at the central part inside the top groove 110. Additionally, the electric push rod 106 can be started, causing the sticker plate 105 connected to its telescopic end to drive the rack 104 to move forward. The other side of the rack 104 is meshed and driven with the gear 103, and the gear 103 is fixedly connected to the outside of the circular seat 102. Therefore, the circular seat 102 will rotate. The top of the circular seat 102 is fitted with the socket joint 108, that is, the fitting between teeth. Thus, the socket joint 108 will drive the double circular plate 109, and the bottom of the groove part 111 will rotate along with it. The top of the groove part 111 remains stationary, so as to play a role in detecting the torsional force test of the groove part 111 itself. Additionally, when conducting a pressure test or a tensile test on the groove part 111, an external torsional force can be applied to conduct multiple test treatments on the groove part 111 itself.

[0050] A central strip 112 is provided at the bottom of the groove member 111. The central strip 112 is fixedly connected to the bottom of the top groove 110. Clamping pieces 113 are symmetrically pressed and adapted on both sides of the groove member 111. The clamping pieces 113 are slidably adapted inside the top groove 110. By inserting the groove member 111 into the top groove 110 opened at the top of the double circular plate 109, then rotating the thrust handle 119 downward, the first extension shaft 115 connected to its central part will deflect counterclockwise. At the same time, the first double-headed plate 116 fixedly connected to the outside of the first extension shaft 115 will deflect counterclockwise accordingly and squeeze the pressure-receiving plug rod 124. The inner end of the first extension shaft 115 is connected to the central shaft 114, the other end of the central shaft 114 is connected to the second extension shaft 117, and the outside of the second extension shaft 117 is connected to the second double-headed plate 118. Therefore, the second double-headed plate 118 will deflect counterclockwise accordingly and squeeze the pressure-receiving plug rod 124 on the other side of the double circular plate 109. The first double-headed plate 116 squeezes the pressure-receiving plug rod 124 on the same side with the bottom of one of its ends, while the second double-headed plate 118 squeezes the pressure-receiving plug rod 124 on the same side with the top of one of its ends. However, both of them will perform squeezing treatment on the pressure-receiving plug rod 124.

[0051] A central shaft 114 is rotatably connected to the central part of the double circular plate 109. One end of the central shaft 114 is fixedly connected to the first extension shaft 115 and the other end is fixedly connected to the second extension shaft 117. One end of the second extension shaft 117 far from the central shaft 114 is fixedly connected to the second double-headed plate 118. One end of the first extension shaft 115 far from the central shaft 114 is fixedly connected to the first double-headed plate 116 and the thrust handle 119 respectively. A triangular plate 1101 is press-fitted at the end of the thrust handle 119 far from the first extension shaft 115. A compensation block 121 is fixedly connected to the outside of the triangular plate 1101. One end of the compensation block 121 close to the double circular plate 109 is fixedly connected to a return spring 122 and an insertion rod 123 respectively. One end of the return spring 122 far from the compensation block 121 is fixedly connected to the outside of the double circular plate 109. The insertion rod 123 penetrates inside the double circular plate 109 and is inserted into the groove member 111 and the clamping piece 113 respectively. By the counterclockwise downward deflection of the thrust handle 119, the triangular plate 1101 originally limited by the top extrusion thereof will move toward the double circular plate 109 under the compression force of the return spring 122. The triangular plate 1101 is connected to the return spring 122 through the compensation block 121, and the surface of the compensation block 121 is fixedly connected to the insertion rod 123. Therefore, under the compression force of the return spring 122, the insertion rod 123 will sequentially pass through the surfaces of the clamping piece 113 and the groove member 111. The clamping piece 113 and the groove member 111 are provided with holes themselves, so as to play a role in preventing the groove member 111 from falling off during the torsional force test because the torsional force is greater than the clamping force, resulting in the failure of the test.

[0052] On the outer side of the first double-headed plate 116, a pressure-receiving plug rod 124 is extrusion-fitted. On the outer side of the pressure-receiving plug rod 124, a sleeve 125 is slidably fitted. The sleeve 125 is fixedly connected to the outer side of the double circular plate 109. A transverse groove 126 is formed at the top of the sleeve 125. A limiting strip 127 is slidably fitted inside the transverse groove 126. One end of the limiting strip 127 away from the transverse groove 126 is fixedly connected to the top of the pressure-receiving plug rod 124. A tubular groove 128 and a spline groove 129 are respectively formed inside the double circular plate 109. An inner frame body 120 is fixedly connected inside the spline groove 129. A first magnetic block 131 is fixedly connected to the outer side of the inner frame body 120. A second magnetic block 132 is arranged at one end of the first magnetic block 131 away from the inner frame body 120. A pressing rod 133 is fixedly connected to one end of the second magnetic block 132 away from the first magnetic block 131. The pressing rod 133 is slidably fitted inside the spline groove 129. One end of the pressing rod 133 away from the second magnetic block 132 is extrusion-fitted with the clamping piece 113. The pressure-receiving plug rod 124 pressed by the first double-headed plate 116 will extend into the sleeve 125. The sleeve 125 communicates with the tubular groove 128 and the spline groove 129 formed inside the double circular plate 109. And the sleeve 125 and both grooves are filled with gas. Therefore, as the pressure-receiving plug rod 124 extends into the sleeve 125, the gas inside it will be compressed and finally enter the spline groove 129. However, the pressing rod 133 is slidably fitted inside the spline groove 129, and the inner end of the pressing rod 133 is connected to the second magnetic block 132. And the spline groove 129 is connected to the first magnetic block 131 through the inner frame body 120. The two magnetic blocks maintain an attracting relationship and play a role in resetting the pressing rod 133. Therefore, as the gas is compressed, the pressing rod 133 will drive the second magnetic block 132 away from the first magnetic block 131 and extend outwards until it presses the clamping piece 113. Finally, the clamping piece 113 will move towards the central part of the top groove 110, so as to completely clamp both sides of the groove part 111.
