[0019] As Figures 1-6 shown, a detection device for the production of battery plates includes an inspection table 1 and a control terminal 2 installed on the end face of the inspection table 1.

[0021] Two baffle plates 8 are symmetrically installed on both sides of the end face of the inspection table 1, and the two baffle plates 8 are inclined. A left strip-shaped hollow plate 9 and a right strip-shaped hollow plate 10 are arranged between the two baffle plates 8. Strip-shaped air jet holes 11 are opened on the side walls of the opposite sides of the left strip-shaped hollow plate 9 and the right strip-shaped hollow plate 10; The air supply unit 12 is installed on the test bench 1. The air supply unit 12 is used to supply air into the left strip-shaped hollow plate 9 and the right strip-shaped hollow plate 10. The air supply unit 12 includes a plunger pump 121 fixedly installed at the bottom of the test bench 1. An air chamber 122 is provided inside the test bench 1 above the plunger pump 121, and the air injection end of the plunger pump 121 is communicated with the inside of the air chamber 122. Two rigid tubes 123 are fixedly communicated with the upper chamber wall of the air chamber 122. Connecting hoses 124 are fixedly inserted at the bottoms of the left strip-shaped hollow plate 9 and the right strip-shaped hollow plate 10, and the two connecting hoses 124 are respectively communicated with the corresponding rigid tubes 123. Air baffle covers 125 are fixedly connected to the inner walls of the left strip-shaped hollow plate 9 and the right strip-shaped hollow plate 10, and the two strip-shaped air injection holes 11 are respectively communicated with the air baffle cover 125 on the same side. A plurality of air inlet holes are provided on the side walls of the two air baffle covers 125, and normally closed electric control valves 126 are installed inside each air inlet hole.

An external air pressure detector 127 is inserted into the upper chamber wall of the air chamber 122, and the external air pressure detector 127 converts the air pressure into an electrical signal and outputs it to the control terminal 2.

[0022] Two driving units 13 are installed on the test bench 1.

[0025] A mounting block 17 is fixedly installed at the lower end of the horizontal part of the support frame 3, and an encoder 18 is installed on the side wall of the mounting block 17. The shaft of the encoder 18 is connected to the pin shaft in a transmission manner, and the encoder 18 is electrically connected to the control terminal 2. The encoder 18 can monitor the rotation angle of the pin shaft in real time through the grating structure and feedback an electrical signal to the control terminal 2.

[0026] The operating principle of the present invention is now described as follows: the electrode plate to be tested is placed inside the U-shaped clamping block 61, so that the electrode tab of the electrode plate is on one side of the pressing block 63. Then, the clamping bolt 62 is tightened, and the clamping bolt 62 drives the pressing block 63 to move, so that the electrode tab of the electrode plate can be clamped and fixed inside the U-shaped clamping block 61 by using the pressing block 63. Then, the control terminal 2 is started, and the control terminal 2 immediately controls the tension detector 71 to work once. The tension detector 71 can detect the total weight of the clamping mechanism 6 and the electrode plate, and converts the tension it receives into an electrical signal and feeds it back to the control terminal 2, which records the electrical signal. Subsequently, the control terminal 2 will immediately control the plunger pump 121 and the electric heater 14 to work. The plunger pump 121 will deliver air to the air cavity 122, and the electric heater 14 can heat the incoming air to a temperature of 55°C ± 2°C. Initially, the control terminal 2 will control all normally closed electric control valves 126 to be energized and opened. At this time, the air inside the air cavity 122 will be ejected from the strip-shaped air injection holes 11 on both sides through the hard tube 123, the connecting hose 124, the left strip-shaped hollow plate 9 and the right strip-shaped hollow plate 10. At the same time, the control terminal 2 controls the two electric push rods 131 to work. , so that the left strip hollow plate 9 and the right strip hollow plate 10 can be moved vertically along the two sides of the plate, and the plate can be heated by the ejected heated airflow, thereby simulating the high temperature environment of the plate when working as much as possible, and keeping the plate within a stable temperature range for detection, making the detection work more practical. After the two electric push rods 131 are extended to the highest point, the control terminal 2 controls the two electric push rods 131 to drive the left strip hollow plate 9 and the right strip hollow plate 10 to move back and reset. Subsequently, the control terminal 2 controls the two normally closed electric control valves 126 to be de-energized and closed; As the normally closed electric control valve 126 is powered off and closed, the air pressure inside the air cavity 122 gradually increases, and the external air pressure detector 127 converts the air pressure into an electrical signal and feeds it back to the control terminal 2. When the air pressure reaches a threshold value (the threshold value is set based on factors such as the weight of the electrode plate, and it is necessary to ensure that the airflow ejected from the strip-shaped air injection hole 11 can push the electrode plate to rotate 30 degrees and generate a sufficiently large impact force when the electrode plate collides with the baffle 8), the electrical signal fed back to the control terminal 2 by the external air pressure detector 127 also reaches the threshold value. At this time, the control terminal 2 controls the normally closed electric control valve 126 inside the left strip-shaped hollow plate 9 to be powered on and opened, and then the high-pressure and high-temperature airflow is ejected through the strip-shaped air injection hole 11 on the side wall of the left strip-shaped hollow plate 9; Among them, after the normally closed electric control valve 126 is powered off and closed, the control terminal 2 will control the electric push rod 131 on the same side as the left strip-shaped hollow plate 9 to work, so that the bottom of the left strip-shaped hollow plate 9 is at the same horizontal line as the bottom of the electrode plate (a ranging probe is installed on the detection table 1, and the ranging probe can detect the height of the lifting block 132. When the height of the lifting block 132 reaches the set value, the ranging probe will feedback an electrical signal to the control terminal 2. At this time, the control terminal 2 controls the electric push rod 131 to stop working, and the set value is set based on the bottom height of the electrode plate). Therefore, when the control terminal 2 controls the normally closed electric control valve 126 inside the left strip-shaped hollow plate 9 to be powered on and opened, since the left strip-shaped hollow plate 9 is on one side of the electrode plate, the ejected air flow will directly impact the side wall of the electrode plate. Under the impact of the high-pressure and high-temperature air flow, the electrode plate rotates to one side about the pin shaft. When it rotates 30°, the electrode plate will hit the baffle 8 on the right side. Subsequently, the electrode plate starts to rotate back and will hit the left strip-shaped hollow plate 9, and then gradually returns to the vertical state. After the normally closed electric control valve 126 inside the left strip-shaped hollow plate 9 works for 2 seconds, the control terminal 2 controls the normally closed electric control valve 126 to be powered off and closed. Subsequently, the electric push rod 131 starts to move back and reset. At this time, the air pressure inside the air chamber 122 rises again. At the same time, when the electrode plate returns to the vertical state, the encoder 18 will detect that the rotation angle of the pin shaft is at the zero position. At this time, it will feedback an electrical signal to the control terminal 2. When the control terminal 2 receives this electrical signal, it starts timing. If the electrode plate is not stable and in a shaking state, the rotation angle of the pin shaft cannot be stably at the zero position angle. At this time, the electrical signal received by the control terminal 2 cannot be continuously maintained. However, when the electrode plate is stably maintained in the vertical state, the electrical signal received by the control terminal 2 can be continuously maintained. When the timing reaches 1 second, it indicates that the electrode plate is maintained in the vertical static state. At this time, the control terminal 2 controls the tension detector 71 to work again, and compares the electrical signal feedback by the tension detector 71 with the electrical signal intensity initially recorded by the control terminal 2, so as to compare the weight change before and after the impact. When the weight loss of the electrode plate exceeds 3%, it indicates that the electrode plate is unqualified (at this time, the alarm module of the control terminal 2 will send an alarm prompt message to remind the staff that the electrode plate is unqualified and display the corresponding information on its own display screen). In the case where the weight loss of the electrode plate does not exceed 3%, the control terminal 2 will control the electric push rod 131 on one side of the right strip-shaped hollow plate 10 to start extending, so that the right strip-shaped hollow plate 10 moves up to the set position, and repeating the above steps can make the electrode plate rotate to the left and hit the baffle 8 on the left side; After the electrode plate swings a certain number of times, if the weight loss of the electrode plate still does not exceed 3%, it indicates that the strength of the electrode plate is large enough. At this time, the control terminal 2 stops the swinging impact work on the electrode plate. (The number of swings is set based on factors such as the detection requirements for the electrode plate and the air pressure threshold set by the external air pressure detector 127, generally set to 10 times, and can be changed through the control terminal 2). After stopping the swinging impact work, the control terminal 2 will control the two electric push rods 131 to work synchronously, so that the left strip-shaped hollow plate 9 and the right strip-shaped hollow plate 10 move up synchronously again. When the bottoms of the left strip-shaped hollow plate 9 and the right strip-shaped hollow plate 10 are on the same horizontal line as the bottom of the electrode plate, the two electric push rods 131 stop working. Then, the control terminal 2 controls the two electromagnetic push rods 133 to work synchronously, and the two electromagnetic push rods 133 push the left strip-shaped hollow plate 9 and the right strip-shaped hollow plate 10 to move towards each other, so as to clamp and fix the electrode plate. And under the action of the frame-shaped sealing gasket 16, a seal is maintained between the side wall of the left strip-shaped hollow plate 9 and the side wall of the electrode plate. Subsequently, the control terminal 2 controls the plunger pump 121 to work again. At the same time, each normally closed electric control valve 126 inside the left strip-shaped hollow plate 9 is controlled to be energized and opened. At this time, the air flow conveyed by the plunger pump 121 will enter the inside of the left strip-shaped hollow plate 9 and contact the electrode plate through the strip-shaped air injection holes 11 on the side wall of the left strip-shaped hollow plate 9. As the air input by the plunger pump 121 increases, the air pressure inside the left strip-shaped hollow plate 9 increases. After the plunger pump 121 works for 20 seconds, the control terminal 2 records the air pressure value detected by the internal air pressure detector 15, and the control terminal 2 controls the plunger pump 121 to stop working synchronously. Since the active material on the surface of the electrode plate is generally provided with certain pores in order to increase the contact area with the electrolyte, at this time, part of the air inside the left strip-shaped hollow plate 9 will escape through the pores of the active material of the electrode plate, thereby reducing the air pressure inside the left strip-shaped hollow plate 9. If the density of the active material is too large, the pores left by the active material are too small and too few, and the air escape speed is slow. After the plunger pump 121 stops working for 10 seconds, the control terminal 2 receives the air pressure value recorded by the internal air pressure detector 15 again, compares this air pressure value with the initially recorded air pressure value, and calculates the difference. When the difference is too large or too small, it indicates that the pores of the active material at this part are too large or too small, affecting its use effect (if the difference is too large, it means that the pores of the active material are too large, affecting its strength. On the contrary, if the pores of the active material are too small, it will affect its full contact with the electrolyte. The difference is set based on the requirements for the porosity of the active material. In the case where the difference is unqualified, the control terminal 2 will give an alarm prompt through its own alarm module and display relevant difference information on its own display screen). If the difference is within the qualified range, the control terminal 2 controls the two electromagnetic push rods 133 to be de-energized, and controls the two electric push rods 131 to continue to extend, so that the left strip-shaped hollow plate 9 and the right strip-shaped hollow plate 10 continue to move up 4 cm, and then repeat the detection action until the side wall of the electrode plate is comprehensively covered and detected. By detecting the air leakage rate,It can fully reflect whether the strength of the plate meets the use requirements. At this point, the plate testing work is completed.
