Technical Field

[0001] The present disclosure relates to the technical field of battery production, and particularly to an electrode powder batching device. Background Art

[0002] With the continuous increase in the market's requirements for the safety performance of batteries, manufacturers' requirements for the quality of electrode powder have become increasingly stringent.

The terms used in the specification of the present disclosure herein are only for the purpose of describing specific embodiments and are not intended to limit the present disclosure. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0033] To better understand the technical solutions and beneficial effects of the present disclosure, the present disclosure will be further described in detail below with specific embodiments:

[0034] As Figure 1 shown, the electrode powder batching device 10 of an embodiment includes a frame 100, a feeding bin 200, a mixer 300, a conveying pipe 400 and a vibrator 500; the feeding bin 200 is installed on the top plate 110 of the frame 100, and the mixer 300 is arranged below the top plate 110 of the frame 100; the conveying pipe 400 is horizontally suspended in the middle of the frame 100, and a feed branch pipe 410 is provided at the top of the pipe wall at the first end of the conveying pipe 400; the bottom of the feeding bin 200 is flexibly connected to the feed branch pipe 410 and communicates with the pipe cavity of the conveying pipe 400; a discharge branch pipe 420 is provided at the bottom of the pipe wall at the second end of the conveying pipe 400; the feeding end of the mixer 300 is flexibly connected to the discharge branch pipe 420 and communicates with the pipe cavity of the conveying pipe 400; the vibrator 500 is installed on the conveying pipe 400 and is arranged close to the feed branch pipe 410.

[0035] It can be understood that by horizontally suspending the material conveying pipe 400 in the middle of the frame 100, since the first end of the material conveying pipe 400 is connected to the bottom of the feeding bin 200 through the feeding branch pipe 410, the electrode powder in the feeding bin 200 can enter the first end of the material conveying pipe 400. By arranging the vibrator 500 on the material conveying pipe 400 close to the feeding branch pipe 410, when the vibrator 500 is turned on, the vibrator 500 will vibrate the first end of the material conveying pipe 400. Since the feeding branch pipe 410 is flexibly connected to the bottom of the feeding bin 200 and the discharging branch pipe 420 is flexibly connected to the feeding end of the mixer 300, when the first end of the material conveying pipe 400 vibrates, the first end of the material conveying pipe 400 will shake up and down in the middle of the frame 100 and tilt towards the second end of the material conveying pipe 400. Because the second end of the material conveying pipe 400 is connected to the feeding end of the mixer 300 through the discharging branch pipe 420, the electrode powder at the first end of the material conveying pipe 400 can slide and jump towards the second end of the material conveying pipe 400 as the material conveying pipe 400 tilts, and finally continuously feed the mixer 300.

[0036] It can be understood that compared with the prior art powder automatic batching device, the electrode powder batching device 10 of the present disclosure makes the material conveying pipe 400 shake up and down and tilt towards the second end of the material conveying pipe 400 through the vibrator 500, so that the electrode powder in the material conveying pipe 400 can continuously slide and jump towards the mixer 300, and the feeding amount can be adjusted by controlling the vibration frequency of the vibrator 500, which can reduce the friction force when the electrode powder is transferred relative to the material conveying pipe 400, thereby reducing the wear of the material conveying pipe 400 and the generation of metal foreign matters.

[0037] Combined with Figure 1 With Figure 2 As shown, in one embodiment, the electrode powder batching device 10 further includes a support suspension 600; the support suspension 600 includes a connected support top plate 610 and a support bottom plate 620; the support top plate 610 and the support bottom plate 620 are arranged on opposite sides of the first end of the material conveying pipe 400, and the bottom of the pipe wall of the first end of the material conveying pipe 400 is fixedly connected to the support bottom plate 620; a connecting pipe 210 is fixedly provided at the bottom of the feeding bin 200, and the connecting pipe 210 penetrates and is fixedly connected to the support top plate 610; the top end of the connecting pipe 210 is communicated with the bottom of the feeding bin 200, the bottom end of the connecting pipe 210 is communicated with the feeding branch pipe 410 through a first hose 411, and the feeding end of the mixer 300 is communicated with the discharging branch pipe 420 through a second hose 421.

[0038] It can be understood that since the connecting pipe 210 is fixedly arranged at the bottom of the feeding bin 200 and fixedly connected to the supporting top plate 610, and the first end of the conveying pipe 400 is arranged between the mutually connected supporting top plate 610 and the supporting bottom plate 620 and fixedly connected to the supporting bottom plate 620, the conveying pipe 400 can be stably lifted by the supporting suspension 600, and it is ensured that the conveying pipe 400 can stably maintain a horizontally arranged state when the vibrator 500 is not started. Thus, the conveying pipe 400 can feed the mixer 300 slowly, which is more conducive to accurately controlling the feeding amount of the conveying pipe 400 to the mixer 300. At the same time, the bottom end of the feeding branch pipe 410 and the connecting pipe 210 are connected through the first hose 411, and the feeding end of the discharging branch pipe 420 and the mixer 300 are connected through the second hose 421, so that when the vibrator 500 is started, the conveying pipe 400 can shake up and down more sensitively relative to the feeding bin 200 and the mixer 300. Furthermore, the shaking feeding speed of the conveying pipe 400 can be accurately controlled by adjusting the vibration frequency of the vibrator 500.

[0039] Combined with Figure 2 As shown, in this embodiment, a plurality of suspension rods 630 are vertically arranged between the supporting top plate 610 and the supporting bottom plate 620. The plurality of suspension rods 630 are spaced apart and distributed on the periphery of the first end of the conveying pipe 400. Both ends of each suspension rod 630 are respectively connected to the supporting top plate 610 and the supporting bottom plate 620. It can be understood that since the bottom of the pipe wall at the first end of the conveying pipe 400 is fixedly connected to the supporting bottom plate 620, the gravity of the conveying pipe 400 will mainly act on the supporting bottom plate 620. By arranging the plurality of suspension rods 630 at intervals on the periphery of the first end of the conveying pipe 400, after the supporting bottom plate 620 is connected to the supporting top plate 610 through each suspension rod 630, the gravity of the conveying pipe 400 received by the supporting bottom plate 620 will be dispersedly conducted to the supporting top plate 610. Thus, the gravity of the conveying pipe 400 can be more evenly distributed, and finally it is ensured that the supporting suspension 600 can lift the entire conveying pipe 400 more smoothly.

[0040] Combined with Figure 1 and Figure 2As shown, in one embodiment, a control unit 111 and at least two first weighing units 112 are provided on the top plate 110 of the rack 100; a hanging port 113 is formed on the top plate 110 of the rack 100, and at least two first weighing units 112 are symmetrically arranged on the periphery of the hanging port 113; the top of the feeding bin 200 passes through the hanging port 113 and extends at least two hanging arms 220 to the peripheral side; each hanging arm 220 presses against and is connected to a first weighing unit 112; a feed quantity regulating valve 211 is provided in the connecting pipe 210, and the control unit 111 is electrically connected to each first weighing unit 112 and the feed quantity regulating valve 211 respectively. It can be understood that by symmetrically arranging the first weighing units 112 at the peripheral position of the hanging port 113, when the feeding bin 200 is connected to the weighing unit through the hanging arms 220, the weight of the feeding bin 200 can be accurately detected by the first weighing units 112. When the weight of the feeding bin 200 changes too fast, it means that the feeding speed of the electrode powder in the feeding bin 200 is too fast. At this time, the control unit 111 can accurately control the feeding speed of the electrode powder by timely adjusting the opening degree of the feed quantity regulating valve 211, and avoid excessive electrode powder entering the conveying pipe 400 to increase the burden on the vibrator 500 and affect the normal feeding of the conveying pipe 400.

[0041] Combined with Figure 2 As shown, in one embodiment, the electrode powder batching device 10 further includes a material blocking assembly 700; the material blocking assembly 700 includes a push-pull driver 710, a telescopic rod 720 and a material blocking partition 730. The push-pull driver 710 is installed at the end of the second end of the conveying pipe 400, and the material blocking partition 730 is slidably arranged in the lumen of the conveying pipe 400; the telescopic rod 720 is arranged between the push-pull driver 710 and the material blocking partition 730, and both ends of the telescopic rod 720 are respectively connected to the material blocking partition 730 and the power output end of the push-pull driver 710, so that the material blocking partition 730 blocks the middle of the conveying pipe 400 or is blocked between the discharge branch pipe 420 and the push-pull driver 710.

[0042] It can be understood that when the amount of the electrode powder in the mixer 300 reaches the target value, although the vibrator 500 is turned off, the electrode powder in the mixer 300 will still continue to be conveyed to the second end of the feed pipe 400 under the action of aftershocks, which affects the batching accuracy. By slidably arranging the baffle partition 730 in the lumen of the feed pipe 400, the push-pull driver 710 can push the baffle partition 730 through the telescopic rod 720, so that the baffle partition 730 can timely block the middle part of the feed pipe 400, making the electrode powder at the first end of the feed pipe 400 unable to continue to be conveyed to the second end of the feed pipe 400, and thus enabling the electrode powder ratio of the mixer 300 to be more accurate. At the same time, when it is necessary to continue feeding the mixer 300, the baffle partition 730 can be pulled by the telescopic rod 720 and stored at a position between the discharge branch pipe 420 and the push-pull driver 710, which can ensure that the electrode powder can smoothly enter the mixer through the discharge branch pipe 420 and can avoid the electrode powder from interfering with the push-pull driver 710.

[0043] Combined with Figure 2 and Figure 3 As shown, in this embodiment, an elastic sheath 721 is sleeved outside the telescopic rod 720; the first end of the elastic sheath 721 abuts against the baffle partition 730 and is fixedly connected to the first end of the telescopic rod 720; the second end of the elastic sheath 721 is close to and fixedly connected to the push-pull driver 710. It can be understood that by fixedly connecting the first end of the elastic sheath 721 to the first end of the telescopic rod 720 and fixedly connecting the second end of the elastic sheath 721 to the push-pull driver 710, the telescopic rod 720 can be wrapped by the elastic sheath 721, avoiding the electrode powder from adsorbing on the telescopic rod 720 and causing wear of the telescopic rod 720, thereby reducing the occurrence of the situation where metal foreign objects are introduced due to the wear of the telescopic rod 720. At the same time, the elastic sheath 721 can stretch and contract with the telescopic rod 720 and will not interfere with the movement of the telescopic rod 720.

[0044] Combined with Figure 3As shown, further, a first positioning hoop 722 is sleeved on the first end of the telescopic rod 720, and the first end of the elastic sheath 721 is embedded between the peripheral wall of the first end of the telescopic rod 720 and the first positioning hoop 722; a buckle edge 711 protrudes around the telescopic rod 720 at the power output end of the push-pull driver 710, and a second positioning hoop 723 is sleeved outside the buckle edge 711, and the second end of the elastic sheath 721 is embedded between the buckle edge 711 and the second positioning hoop 723. It can be understood that by embedding the first end of the elastic sheath 721 between the peripheral wall of the first end of the telescopic rod 720 and the first positioning hoop 722, the first end of the elastic sheath 721 can be tightly sleeved on the first end of the telescopic rod 720, and by embedding the second end of the elastic sheath 721 between the buckle edge 711 and the second positioning hoop 723, the second end of the elastic sheath 721 can be tightly connected to the push-pull driver 710, so that the telescopic rod 720 can be better wrapped, enhancing the protection effect on the telescopic rod 720.

[0045] Combined Figure 1 with Figure 2 As shown, in one embodiment, a second weighing unit 311 is provided on the support leg 310 of the mixer 300, and a discharge regulating valve 422 is provided in the discharge branch pipe 420. The second weighing unit 311 is electrically connected to the vibrator 500, the push-pull driver 710 and the discharge regulating valve 422 respectively. It can be understood that by providing the second weighing unit 311 on the support leg 310 of the mixer 300, the amount of electrode powder in the mixer 300 can be sensed by the second weighing unit 311. Since the second weighing unit 311 is electrically connected to the vibrator 500 and the discharge regulating valve 422 respectively, when the amount of electrode powder reaches the target value, the second weighing unit 311 can timely control the vibrator 500 to close, and synchronously control the push-pull driver 710 to push the baffle 730 to block the middle of the conveying pipe 400 and close the discharge regulating valve 422. Blocking the middle of the conveying pipe 400 by the baffle 730 can prevent the electrode powder from continuing to be conveyed to the conveying pipe 400 under the action of aftershock, and closing the discharge regulating valve 422 can separate the mixer 300 from the outside, so as to prevent the remaining material of the electrode powder in the conveying pipe 400 from entering the mixer 300 and causing the mixing ratio of the electrode powder to exceed the standard. Among them, the mixer 300 can be a plowshare mixer, but it is not limited here.

[0046] In one embodiment, specifically, the first weighing unit 112 or the second weighing unit 311 can specifically adopt a weighing sensor, and the control unit 111 can specifically adopt a PLC (Programmable Logic Controller) or a single-chip microcomputer, which is not limited here.

[0047] It should be noted in particular that the method for the first weighing unit 112 to detect the weight of the feeding bin 200, the method for signal transmission between the first weighing unit 112 and the control unit 111, the method for the control unit 111 to adjust the opening degree of the feed rate regulating valve 211, the method for the second weighing unit 311 to control the vibration motor 500 to close, and the method for the second weighing unit 311 to control the push-pull driver 710 are all prior arts and not within the protection scope of the present disclosure. The present disclosure only protects the positional relationship and connection relationship between the various components of the electrode powder batching device 10.

[0048] Combined with Figure 2 and Figure 4 it can be seen that in one embodiment, a plurality of buffer baffles 430 protrude from the bottom of the lumen of the feed pipe 400, and the plurality of buffer baffles 430 are arranged at intervals between the first end and the second end of the feed pipe 400. It can be understood that when the electrode powder jumps and slides from the first end to the second end of the feed pipe 400, since the plurality of buffer baffles 430 are arranged at intervals between the first end and the second end of the feed pipe 400, the sliding speed of the electrode powder will be slowed down by the interference of the buffer baffles 430. After the sliding speed of the electrode powder is slowed down, it can be more finely controlled, and finally accurate feeding to the mixer 300 is achieved.

[0049] Combined with Figure 5 it can be seen that in this embodiment, both ends of the buffer baffle 430 extend along the circumferential wall of the lumen of the feed pipe 400 in an arc shape, and a material passing notch 431 is formed in the middle of the buffer baffle 430; the material passing notches 431 are arranged opposite to each other and form a feeding channel. It can be understood that since both ends of the buffer baffle 430 extend along the circumferential wall of the lumen of the feed pipe 400 in an arc shape, the electrode powder in the feed pipe 400 will be interfered by the buffer baffle 430 and slide and accumulate at the material passing notch 431 in the middle of the buffer baffle 430 after jumping up. After the electrode powder accumulates, the moving speed becomes slow. At the same time, with the up and down shaking of the feed pipe 400, the electrode powder is synchronously conveyed along the feeding channel to the second end of the feed pipe 400, which can ensure continuous and coherent feeding to the mixer 300 while slowing down the conveying speed of the electrode powder.

[0050] In one embodiment, the electrical connection can be in various forms such as wired connection, wireless connection, etc. It can be understood that the wired connection can be a wire connection or a circuit board connection, etc., and the wireless connection can use a Bluetooth connection or a WIFI (Wireless Fidelity) connection, etc. The specific connection method is not limited, and those skilled in the art can also adjust according to needs.

[0051] In one embodiment, for better understanding, the following is an explanation of the use process of the electrode powder batching device 10 in this embodiment:

[0052] Combined Figure 2 As shown, first, electrode powder is put into the feeding bin 200. The electrode powder enters the first end of the conveying pipe 400 from the feeding branch pipe 410. The vibrator 500 is turned on and the vibration frequency is adjusted to 50HZ. The first end of the conveying pipe 400 shakes up and down and tilts towards the second end of the conveying pipe 400, and the electrode powder accelerates into the mixer 300. When the weight of the electrode powder in the mixer 300 is still 13 kg short of the target value, the vibration frequency of the vibrator 500 is reduced to 28HZ. When the electrode powder falling from the feeding bin 200 in 4 seconds is less than 0.1 kg, the vibration frequency of the vibrator 500 is increased by 1HZ. When the electrode powder falling from the feeding bin 200 in 4 seconds is greater than 0.3 kg, the vibration frequency of the vibrator 500 is reduced by 1HZ. When the weight of the electrode powder in the mixer 300 reaches the target value, the vibrator 500 is turned off, so as to realize slow and accurate feeding to the mixer 300.

[0053] Compared with the prior art, the present disclosure has at least the following advantages:

[0054] 1) By horizontally suspending the conveying pipe 400 in the middle of the frame 100, since the first end of the conveying pipe 400 is connected to the bottom of the feeding bin 200 through the feeding branch pipe 410, the electrode powder in the feeding bin 200 can enter the first end of the conveying pipe 400. By arranging the vibrator 500 on the conveying pipe 400 close to the feeding branch pipe 410, when the vibrator 500 is turned on, the vibrator 500 will vibrate the first end of the conveying pipe 400. Since the feeding branch pipe 410 is flexibly connected to the bottom of the feeding bin 200 and the discharging branch pipe 420 is flexibly connected to the feeding end of the mixer 300, when the first end of the conveying pipe 400 vibrates, the first end of the conveying pipe 400 will shake up and down in the middle of the frame 100 and tilt towards the second end of the conveying pipe 400. Because the second end of the conveying pipe 400 is connected to the feeding end of the mixer 300 through the discharging branch pipe 420, the electrode powder at the first end of the conveying pipe 400 can slide and jump towards the second end of the conveying pipe 400 as the conveying pipe 400 tilts, and finally continuously feed the mixer 300.

[0055] 2) Compared with the prior art powder automatic batching device, the electrode powder batching device 10 of the present disclosure makes the conveying pipe 400 shake up and down and tilt towards the second end of the conveying pipe 400 through the vibrator 500, so that the electrode powder in the conveying pipe 400 can continuously slide and jump towards the mixer 300, and the feeding amount can be adjusted by controlling the vibration frequency of the vibrator 500, which can reduce the friction force when the electrode powder is transferred relative to the conveying pipe 400, thereby reducing the wear of the conveying pipe 400 and the generation of metal foreign matters.

[0056] The above-described embodiments merely represent several implementation manners of the present disclosure. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present disclosure, several modifications and improvements can still be made, and these all fall within the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure patent shall be subject to the appended claims.
