A device for detecting positive and negative electrodes of a battery

Abstract

The present invention relates to the technical field of battery positive and negative electrode detection, and specifically to a device for detecting battery positive and negative electrode sheets, comprising a fixing frame, a detection mechanism and a conveying mechanism installed on the fixing frame, wherein an electrode sheet is placed on the conveying mechanism, and a film-lifting mechanism is installed on the clamping mechanism; when the clamping plate clamps the electrode sheet, it drives two support frames to move relative to each other, and before detection, cylinder four is started to drive two horizontal bars to move relative to each other. Since a larger gap is blown out between the diaphragm and the electrode sheet, as cylinder four extends, two sets of seesaw plates are inserted into the gap between the electrode sheet and the diaphragm, and then cylinder three is started. Cylinder three contracts at this time, so that two connecting rods pull two tooth plates at the same time. After the two tooth plates move relative to each other, they drive two gears to rotate, and the directions are opposite. At this time, the two driving rods drive the two seesaw plates to rotate in opposite directions, thereby increasing the gap between the diaphragm and the electrode sheet, and preventing the diaphragm from swinging at the bottom of the detection needle and affecting the detection.

Description

Technical Field

[0001] The present invention relates to the technical field of battery positive and negative electrode sheet detection, in particular to a device for detecting battery positive and negative electrode sheets. Background Art

[0002] The positive and negative electrodes are the core components of a battery, directly affecting its energy density, charge and discharge performance, cycle life, and safety. A battery is composed of a positive electrode, a negative electrode, and a separator. During assembly, a separator is placed between adjacent positive and negative electrodes. A resistance meter is typically used to test the positive and negative electrodes.

[0003] However, at present, when the battery electrodes are inspected by a resistor meter, the electrode sheets are generally inspected by the resistor meter. During the inspection, the battery electrode sheets need to be manually placed on the table and the cylinder is used to drive the inspection to inspect the electrode sheets. Not only is it difficult to realize automatic loading, but the position of the electrode sheets is not fixed each time, the inspection needle is difficult to move horizontally, and the electrode sheets being inspected are not clamped to them, and are easily offset when blowing, and the placement position of the electrode sheets needs to be adjusted multiple times, resulting in low inspection efficiency; before the inspection needle contacts the electrode sheet, the diaphragm on the electrode sheet is blown up by the air nozzle to open the inspection position. Due to the good flexibility of the diaphragm, the diaphragm is not opened significantly when the air nozzle blows up the diaphragm, and is easy to swing, affecting the contact between the inspection needle and the inspection point, which is not conducive to the inspection of the electrode sheet; after the inspection, the positive electrode sheet or the negative electrode sheet is judged only by the resistance displayed by the resistor meter, and it is not marked after the inspection, which easily causes the electrode sheet information after the inspection to be forgotten, and it is necessary to inspect again, which wastes time.

[0016] (1) The present invention relates to a device for detecting positive and negative electrodes of a battery. A conveying mechanism and a detecting mechanism are installed on a fixed frame. When the electrode sheet of the battery is detected, it is placed on a conveyor belt to realize automatic loading. When the electrode sheet reaches the bottom of the detection needle, the conveyor belt stops. At this time, the bidirectional cylinder can be started to drive the two moving bars to move relative to each other, and further realize that the two push plates drive the clamping plates to move relative to each other to clamp the electrode plate to be detected, and quickly level it, which is conducive to the rapid contact detection between the detection needle and the electrode sheet. The slider can be driven by the motor to move on the slide rail to realize the horizontal movement of the detection needle, which is conducive to finding the detection position. Then the cylinder 2 lowers the air nozzle to blow air to the diaphragm on the electrode sheet, so that the diaphragm is quickly blown up, which is convenient for the detection of the detection needle.

[0017] (2) The present invention relates to a device for detecting positive and negative electrodes of a battery. Two film-lifting mechanisms are installed on the clamping mechanism. When the clamping plates clamp the electrode plates, they drive the two support frames to move relative to each other. Before the detection, cylinder four is started to drive the two horizontal bars to move relative to each other. Since a larger gap is blown out between the diaphragm and the electrode plates, the two sets of seesaw plates are inserted into the gap between the electrode plates and the diaphragm as cylinder four extends. Then cylinder three is started and cylinder three contracts at this time, so that the two connecting rods pull the two tooth plates at the same time. After the two tooth plates move relative to each other, they drive the two gears to rotate in opposite directions. At this time, the two driving rods drive the two seesaw plates to rotate in opposite directions, thereby increasing the gap between the diaphragm and the electrode plates and preventing the diaphragm from swinging at the bottom of the detection needle and affecting the detection.

[0018] (3) The device for detecting positive and negative electrodes of a battery described in the present invention has a marking mechanism installed on a fixed frame. When the electrode sheet is detected as a positive electrode sheet or a negative electrode sheet, the conveyor belt transports it. When the detected electrode sheet is transported to the bottom of the pressure rod, the staff can press the corresponding control switch to press the corresponding pressure rod, so that the positive electrode mark plate or the negative electrode mark plate can leave a "+" or "-" sign on the diaphragm of the electrode sheet, which is conducive to quickly distinguishing whether the electrode sheet is a positive electrode sheet or a negative electrode sheet, and avoiding forgetting and causing re-testing.

The bottoms of the two top frames 601 are installed with cylinder three 603, and the telescopic ends of cylinder three 603 are fixedly connected with connecting blocks 613. Two tooth plates 607 are relatively slidably connected to the horizontal bars 605, and the tooth plates 607 are meshed with gears 606. The two tooth plates 607 on the same side are rotatably connected to the connecting blocks 613 with connecting rods 614; the film lifting mechanism 6 also includes a support seat 609 and a roller 610. Two groups of support seats 609 are relatively fixedly connected to the conveying mechanism 3, and the two support seats 609 on the same side are equidistantly rotatably connected with rollers 610; the driving rod 612 is inclined, and the surface of the rocker 602 at the end of the driving rod 612 is inclined;When the two-way cylinder 504 drives the two push frames 502 to move relative to each other, the components on the two support frames 608 also move relative to each other. However, at this time, the two sets of rockers 602 have not yet been inserted into the gap between the electrode sheet 4 and the diaphragm. At this time, the air nozzle 208 is still in the blowing state, and then the two cylinders four 604 are started to extend the telescopic ends of the two cylinders four 604. Then the two horizontal bars 605 move relative to each other, and the two sets of rockers 602 are gradually inserted into the gap between the two diaphragms and the electrode sheet 4. After full insertion, the two cylinders three 603 are contracted to drive the two connecting blocks 613 to move back to each other. Since the connecting rod 614 is rotatably connected to the connecting block 613 and the tooth plate 607, when the cylinder three 603 pulls the connecting rod 614, the two The two connecting rods 614 slide relative to each other, and because the two toothed plates 607 mesh with the gears 606 on the two drive shafts 611, when the two toothed plates 607 move relative to each other, the two gears 606 rotate in opposite directions, further causing the drive shafts 611 to rotate in opposite directions, and the two drive rods 612 in the same group to move in opposite directions. Ultimately, the seesaw 602 significantly opens the two diaphragms, facilitating the exposure of the detection points on the electrode sheet 4 and facilitating contact detection between the detection needle 207 and the contact point. After the detection is completed, the cylinder 3 603 extends, and the two connecting rods 614 push the toothed plates 607 to move in opposite directions, thereby resetting the seesaw 602. The cylinder 4 604 is then retracted, and the seesaw 602 is withdrawn from the gap without affecting the conveyance of the electrode sheet 4 by the conveyor belt 303.

[0034] Specifically, such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9As shown, the conveying mechanism 3 includes a mounting frame 301 and a connecting plate 304. The mounting frame 301 is fixedly connected to the fixing frame 1 through two sets of connecting plates 304. The movable groove 501 is opened on both sides of the mounting frame 301. The two sets of support seats 609 are fixedly connected to the mounting frame 301. The middle part of the mounting frame 301 is in a U-shaped structure; the conveying mechanism 3 also includes a roller 305. The mounting frame 301 is rotatably connected to the roller 305. The conveyor belt 303 is installed on the roller 305. The side of the mounting frame 301 is installed with a second motor 302. The second motor 302 The output end is connected to the roller 305 through a coupling; the clamping mechanism 5 includes a bottom plate 503, a bottom plate 503 is installed on the inner side of the mounting frame 301, a two-way cylinder 504 is installed at the center of the surface of the bottom plate 503, the two telescopic ends of the two-way cylinder 504 are fixedly connected to the push frame 502 with an L-shaped structure on the side, the tops of the two push frames 502 are fixedly connected to a moving bar 509, the moving bar 509 is slidably connected to the mounting frame 301, and the opposite ends of the two moving bars 509 are fixedly connected to push plates 505; the clamping mechanism 5 also includes Two sets of guide rods 506, two push plates 505 are equidistantly connected to a plurality of guide rods 506 for sliding, the ends of the two sets of guide rods 506 are fixedly connected to a clamping plate 507, and a plurality of springs 508 located on the guide rods 506 are clamped between the clamping plate 507 and the push plate 505; the detection mechanism 2 includes a shell 205, a side wall of the fixed frame 1 is mounted with the shell 205, the interior of the shell 205 is mounted with two parallel slide rails 211, the two slide rails 211 are slidably connected to the slide seat 212, the interior of the shell 205 is rotatably connected to two drive wheels 209, the two A belt 210 is installed between the two drive wheels 209, and the belt 210 is fixedly connected to the slide 212. A motor 1 201 is installed on the housing 205, and the output end of the motor 1 201 is fixedly connected to one of the drive wheels 209. A slide 202 with an L-shaped side structure is fixedly connected to the slide 212. A cylinder 1 203 and a cylinder 2 204 are installed on the slide 202. A detection box 206 is installed at the bottom of the cylinder 1 203, and a detection needle 207 is provided at the bottom of the detection box 206. A gas nozzle 208 is installed at the bottom of the cylinder 204.When detecting whether the electrode sheet 4 is a positive electrode sheet or a negative electrode sheet, turn on the second motor 302 to drive a roller 305 to rotate. When installing the roller 305, install two of them, and the conveyor belt 303 is installed on the roller 305. After starting the second motor 302, the conveyor belt 303 rotates, and the electrode sheet 4 can be placed on the conveyor belt 303 to realize automatic transportation. When the electrode sheet 4 is transported to the bottom of the detection needle 207, the second motor 302 can be stopped. After stopping the conveyor belt 303, the two-way cylinder 504 located on the bottom plate 503 can be started. After the two two-way cylinders 504 shrink, they drive the two push racks 502 to move relative to each other. At this time, the moving bars 509 at the ends of the two push racks 502 are also driven to move relative to each other, further realizing that the two splints 507 clamp the electrode sheet 4, realizing that the electrode sheet 4 is quickly leveled, and when the air nozzle 208 blows air, the electrode sheet 4 will not deviate, and the clamping plate 507 is provided with a guide rod 506 and a spring 1 508. The guide rod 506 can slide on the push plate 505, and the spring 1 508 is stressed, so that electrode sheets 4 of different widths can be leveled and clamped. After clamping, the air cylinder 204 can be activated to lower the air nozzle 208 to blow up the diaphragm on the electrode sheet 4, exposing the detection position. The air cylinder 1 203 is further activated to lower the detection box 206. The detection needle 207 contacts the detection point on the electrode sheet 4, and the resistance change can be observed on the resistance meter. The larger the resistance, the positive electrode sheet, and the opposite is the case with the negative electrode sheet. If the horizontal position detection needle 207 does not correspond to the detection point on the electrode sheet 4, the motor 1 201 is activated to drive the belt 210 to rotate, further enabling the slide 212 to move on the slide rail 211, thereby adjusting the position of the slide 202, which is conducive to adjusting the position of the detection needle 207.

[0035] Specifically, such as Figure 1 and Figure 11As shown, a marking mechanism 7 is installed on the fixing frame 1, and the marking mechanism 7 includes a fixing frame 701, a fixing frame 701 is installed on the fixing frame 1, and two cylinders 5 702 are installed on the fixing frame 701, and the two cylinders 5 702 both penetrate the bottom of the fixing frame 701, and the bottom of the fixing frame 701 is fixedly connected to the limit frame 704, and the limit frame 704 is relatively slidably connected to two pressure rods 705 located at the bottom of the cylinder 5 702, and the bottoms of the two pressure rods 705 are respectively provided with a positive mark plate 707 and a negative mark plate 708, and the fixing frame 701 is equipped with two control switches 703 respectively connected to the two cylinders 5 702; the marking mechanism 7 also includes a spring 2 706, and a spring 2 706 is clamped between the two pressure rods 705 and the limit frame 704; the electrode sheet 4 after detection will be transported to the bottom of the fixing frame 701 by the conveyor belt 303, and at this time the motor 2 302 will also stop rotating, and the detected electrode sheet 4 will be at When at the bottom of the two pressure rods 705, the staff will know whether the electrode sheet 4 is a positive electrode sheet or a negative electrode sheet, and then press the corresponding control switch 703 to control the corresponding cylinder five 702 to extend, that is, to select which pressure rod 705 to descend. If the electrode sheet 4 is a positive electrode sheet, the pressure rod 705 of the positive plate 707 will be controlled to descend. If the electrode sheet 4 is a negative electrode sheet, the other cylinder five 702 will be controlled to descend. No matter which cylinder five 702 descends, it will squeeze the corresponding pressure rod 705, and the spring two 706 will contract. Further, the positive plate 707 or the negative plate 708 at the bottom of the pressure rod 705 will leave a mark on the diaphragm on the electrode sheet 4, avoiding forgetting the electrode sheet 4 that has been detected, which is conducive to identification, and the positive plate 707 and the negative plate 708 only need to be smeared with ink or paint at the specified time. After detection, the motor two 302 is started and the conveyor belt 303 continues to unload.

[0036] When the present invention is in use, first, when detecting whether the electrode sheet 4 is a positive electrode sheet or a negative electrode sheet, the second motor 302 is turned on to drive a roller 305 to rotate. When installing the roller 305, two rollers are installed, and the conveyor belt 303 is installed on the roller 305. After starting the second motor 302, the conveyor belt 303 is rotated, and the electrode sheet 4 can be placed on the conveyor belt 303 to realize automatic transportation. When the electrode sheet 4 is transported to the bottom of the detection needle 207, the second motor 302 can be stopped. After the conveyor belt 303 is stopped, the two-way cylinder 504 located on the bottom plate 503 can be started. After the two two-way cylinders 504 are contracted, they drive the two push racks 502 to move relative to each other. At this time, the moving bars 509 at the ends of the two push racks 502 are also driven to move relative to each other, further realizing that the two clamping plates 507 clamp the electrode sheet 4, realizing that the electrode sheet 4 is quickly leveled, and the air nozzle 208 When blowing, the electrode sheet 4 will not deviate, and a guide rod 506 and a spring 1 508 are provided on the clamping plate 507. The guide rod 506 can slide on the push plate 505, and the spring 1 508 is stressed, so that the electrode sheets 4 of different widths can be leveled and clamped. After clamping, the cylinder 204 can be started to realize the lowering of the air nozzle 208 to blow up the diaphragm on the electrode sheet 4 to expose the detection position, and the cylinder 1 203 is further started to realize the lowering of the detection box 206. The detection needle 207 contacts the detection point on the electrode sheet 4, and the resistance change can be observed on the resistance meter. The larger the resistance, the positive electrode sheet, and vice versa. If the horizontal position detection needle 207 does not correspond to the detection point on the electrode sheet 4, the motor 1 201 is started to drive the belt 210 to rotate, and the slide 212 can be further moved on the slide rail 211, thereby adjusting the position of the slide 202, which is conducive to the adjustment of the position of the detection needle 207.

[0037] Then, when the two-way cylinder 504 drives the two push frames 502 to move relative to each other, the components on the two support frames 608 also move relative to each other. However, at this time, the two sets of rockers 602 have not yet been inserted into the gap between the electrode sheet 4 and the diaphragm. At this time, the air nozzle 208 is still in the blowing state. Then, the two cylinders 4 604 are started to extend the telescopic ends of the two cylinders 4 604. Then, the two horizontal bars 605 move relative to each other, and the two sets of rockers 602 are gradually inserted into the gap between the two diaphragms and the electrode sheet 4. After full insertion, the two cylinders 3 603 are retracted to drive the two connecting blocks 613 to move back to each other. Since the connecting rod 614 is rotatably connected to the connecting block 613 and the tooth plate 607, when the cylinder 3 603 pulls the connecting rod 614, it is realized. The two connecting rods 614 slide relative to each other, and since the two tooth plates 607 are engaged with the gears 606 on the two drive shafts 611, when the two tooth plates 607 move relative to each other, the two gears 606 will rotate in opposite directions, further realizing the drive shaft 611 to rotate in opposite directions, and the two drive rods 612 of the same group to move in opposite directions, and finally realizing the seesaw 602 to significantly open the two diaphragms, which is beneficial to the exposure of the detection points on the electrode sheet 4 and the convenience of the detection needle 207 to the contact detection. After the detection is completed, the cylinder three 603 is extended, and the two connecting rods 614 push the tooth plates 607 to move in opposite directions, thereby realizing the reset of the seesaw 602, and the cylinder four 604 is contracted to pull the seesaw 602 out of the gap, which will not affect the electrode sheet 4 being transported by the conveyor belt 303;

[0038] Finally, the electrode sheet 4 after detection will be conveyed to the bottom of the fixed frame 701 by the conveyor belt 303. At this time, the motor 2 302 will also stop rotating. When the electrode sheet 4 being detected is at the bottom of the two pressure rods 705, the staff will know whether the electrode sheet 4 is a positive electrode sheet or a negative electrode sheet. Then, the staff will press the corresponding control switch 703 to control the corresponding cylinder 5 702 to extend, that is, to select which pressure rod 705 to descend. If the electrode sheet 4 is a positive electrode sheet, the pressure rod 705 of the positive standard plate 707 will be controlled to descend. If the electrode sheet 4 is a negative electrode sheet, Then the other cylinder five 702 is controlled to descend. No matter which cylinder five 702 descends, the corresponding pressure rod 705 will be squeezed, and the spring two 706 will contract. Further, the positive plate 707 or the negative plate 708 at the bottom of the pressure rod 705 will leave a mark on the diaphragm on the electrode sheet 4, so as to avoid forgetting the electrode sheet 4 that has been tested, which is conducive to identification. The positive plate 707 and the negative plate 708 only need to be coated with ink or paint at the specified time.
