Description

Technical Field

[0001] The present invention relates to the technical field of battery production, and in particular to a conveying device for battery sorting and correction. Background Art

[0002] As a classic form of lithium-ion batteries, cylindrical batteries have a long history and wide application.

[0003] Cylindrical batteries face multiple technical challenges during automated conveying and sorting, primarily due to their physical properties, such as cylindrical shape, metal casing, exposed electrodes, and corresponding safety requirements. Furthermore, existing cylindrical batteries are subject to bumps and other collisions during transportation, which can cause dents on the surface of some batteries due to external forces. Generally, operators visually inspect and pick out obvious dents, but these are prone to omission when conveying large quantities of cylindrical batteries, and cannot be quickly sorted for subtle dents. Therefore, we propose a battery sorting and correction conveying device to address these issues. Summary of the Invention

[0004] The object of the present invention is to provide a conveying device for battery sorting and correction to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a battery sorting and correction conveying device, comprising:

[0006] A connecting base is provided, a support plate is provided at the rear end of the connecting base, a feed rack is installed on the support plate, a loading track is installed on the support plate, the unloading port of the loading track corresponds to the feed rack, an electrode detection mechanism is provided on the top of the connecting base, the feed rack is composed of a pair of fixed baffles, a guide plate and a blocking plate, and a correction conveying roller is provided inside the feed rack for rotation;

[0007] Among them, a number of correction grooves are opened on the correction conveying roller, and a connecting frame is provided inside the correction grooves. A number of battery auxiliary conveying limit shafts are installed inside the connecting frame, and connecting plates are installed at both ends of the correction grooves. A number of pressure-sensitive sensors for external roundness detection are provided on the connecting plates. A dust suction pipe is inserted into the correction conveying roller. When the battery needs to be conveyed, as the battery is fed along the feeding track, the battery can be conveyed to the inside of the feeding frame, and the battery can be evenly clamped in the correction groove. As the correction conveying roller moves in a circle, the battery can be clamped inside the correction conveying roller. During the conveying process, with the cooperation of the movable insertion rod and the pressure-sensitive sensor, the battery with pit defects on the surface can be detected, and the defective products can be sorted out, thereby reducing the defective product rate in subsequent production.

[0008] Preferably, the feed rack is provided with a set of chutes, and a sliding shaft is clamped inside the chutes. A buffer rack is provided on the sliding shaft. The buffer rack is composed of a set of parallel bent plates and a fixed plate, and the fixed plate is arranged at an angle and fits on the guide plate. The guide plate is used for battery feed transmission, and the buffer rack is used for buffering to reduce surface depression caused by bumps during transportation.

[0009] An arc-shaped adsorption baffle is installed inside the buffer rack, and a number of adsorption sheets are arranged inside the adsorption baffle. Adhesive plates are provided on both sides of the adsorption sheets. A toggle plate is connected to the outer wall of the adsorption baffle. A number of chip removal grooves are provided on the fixed plate of the buffer rack. A rectangular groove connected to the fixed screen plate is provided on the top of the buffer rack. The buffer rack shortens the drop of the battery from the feed track to the feed rack, thereby minimizing the risk of damage such as bumps, scratches, extrusion deformation, etc. to the battery during transportation, positioning, pressing, and testing, and protecting the integrity of the battery appearance.

[0010] Preferably, a clamping shaft is installed inside the feed rack, a plurality of reset plates are provided on the top of the clamping shaft, a plurality of straight grooves corresponding to the reset plates are opened on the buffer rack, and the reset plates are against the toggle plates during the swinging process;

[0011] A number of arc-shaped pressure plates are provided at the bottom of the clamping shaft. The arc-shaped pressure plates are located on the outside of the correction conveying roller and are used to press the battery into the correction groove. A rubber gasket is provided inside the arc-shaped pressure plate to drive the battery to rotate inside the correction groove during the circular motion of the correction conveying roller. The correction groove on the correction conveying roller is used to fix the battery, and the friction force of the arc-shaped pressure plate is used to make the battery rotate in a circle during the conveying process.

[0012] Preferably, a plurality of elastic pads are provided on the limiting shaft, and the elastic pads are arranged in a uniform array on the limiting shaft, which can play a buffering role and reduce the scratching of the battery surface;

[0013] A circular groove is provided on the correction conveying roller, and the circular groove is connected with the correction groove. A plurality of rubber sheets connected with the bottom of the correction groove are provided inside the correction conveying roller.

[0014] Preferably, the pressure-sensitive sensor is provided with a group of docking tubes, and a movable rod is inserted inside the docking tubes, the top of the movable rod is against the outer wall of the battery, and the bottom of the movable rod is provided with a buffer pad for resting on the receiving end of the pressure-sensitive sensor, and an audible and visual alarm is provided inside the connecting plate. When the movable rod is tightened and the pressure changes too much when the battery rotates, the audible and visual alarm can play a predictive role. The outer wall of the battery is in close contact with the pressure-sensitive sensor and the movable rod provided on the connecting plate. When the battery rotates, any depression or irregularity on its surface will cause the pressure change of the movable rod to be captured in real time by the pressure-sensitive sensor, triggering the audible and visual alarm, thereby realizing online, dynamic, and high-precision detection of the outer roundness of the battery during continuous transportation, effectively eliminating defective products with defects such as pits on the surface, and significantly reducing the defective rate of subsequent processes.

[0015] Preferably, a sealing plate is connected to the outside of the dust suction tube, and a guide groove that passes through the external equipment is provided on the sealing plate. A number of arc-shaped depressions are provided on the outside of the dust suction tube, and an elastic grid sheet is provided inside the arc-shaped depression. The position of the grid sheet corresponds to the position of the rubber sheet. The rubber sheet inside the correction roller is squeezed and compressed with the grid sheet, and dust and debris are adsorbed with the help of the grid sheet, which is convenient for subsequent cleaning.

[0016] Preferably, the electrode detection mechanism includes a slide plate and a control cylinder, and the slide plate is installed on the top of the connecting base, the control cylinder is movably arranged on the top of the slide plate, the connecting base is provided with a pair of discharge grooves, which are respectively located on the feed rack and the bottom of the electrode detection mechanism, and the slide plate is provided with a transmission groove corresponding to one side of the discharge groove, and one side of the control cylinder is provided with a group of conveying rods connected to the detection plate for detecting the position of the electrode;

[0017] A docking plate is provided on one side of the bottom of the feed rack, and a movable baffle is interactively provided inside the docking plate for exporting defective batteries, and an arc-shaped baffle is connected to one side of the slide plate, which can play a blocking role and export the batteries from the discharge chute.

[0018] Preferably, a buffer baffle is provided at the top of the blocking plate, and the cross-section of the buffer baffle is "U"-shaped, which reduces the risk of damage to the battery such as bumps, scratches, extrusion deformation, etc. during transportation.

[0019] Preferably, a group of rectangular movable frames are inserted at the top of the feeding track, and a positioning plate is connected to the top of the movable frame. A rotating ring is rotatably provided on the positioning plate, and a threaded groove is provided inside the rotating ring. The top of the feeding track is connected to a threaded rod inserted inside the rotating ring, which can flexibly adapt to batteries of different sizes and specifications, ensuring that the batteries are fed stably and evenly in the track, and effectively preventing jamming or misalignment caused by inappropriate gaps.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The present invention fixes the battery by means of the correction groove on the correction conveying roller, and cooperates with the friction of the arc-shaped pressure plate to make the battery rotate in a circle during the conveying process. The outer wall of the battery is in close contact with the pressure-sensitive sensor and the movable insertion rod provided on the connecting plate. When the battery rotates, any depression or irregularity on its surface will cause the pressure change of the movable insertion rod to be captured in real time by the pressure-sensitive sensor, triggering an audible and visual alarm. This realizes the online, dynamic, and high-precision detection of the outer roundness of the battery during the continuous conveying process, effectively eliminating defective products with defects such as pits on the surface, and significantly reducing the defective product rate in subsequent processes.

[0022] 2. The present invention shortens the drop of batteries from the feed track to the feed rack by providing a buffer rack; the buffer baffle prevents the batteries from rushing out; the rubber gasket inside the arc-shaped pressure plate provides buffering and pressing; the elastic pad on the limit shaft provides flexible contact. The multi-layer buffer design minimizes the risk of damage such as bumps, scratches, and extrusion deformation during transportation, positioning, pressing, and testing, thereby protecting the integrity of the battery appearance.

[0023] 3. The present invention separates debris and dust during transportation by using a fixed screen plate and a chip removal chute. The battery strikes the buffer frame and vibrates, causing dust to be adsorbed onto the adhesive plate inside the adsorption baffle. When the battery rotates, it rubs against the elastic pad on the limit shaft to clean the surface dust. The dust suction pipe absorbs dust in the correction groove through the circular groove. During the transportation and testing process, dust on the battery surface is simultaneously cleaned and debris generated in the system is collected, keeping the interior of the equipment clean and extending the equipment maintenance cycle.

[0024] 4. The present invention utilizes a movable frame, positioning plate, rotating ring, and threaded rod at the top of the feeding track to form an adjustable width mechanism. Rotating the rotating ring changes the gap between the bottom of the movable frame and the track, flexibly adapting to batteries of different sizes and specifications, ensuring stable and uniform battery feeding within the track. This effectively prevents jamming or misalignment caused by inappropriate gaps, thereby enhancing the equipment's applicability and feeding reliability.

[0025] 5. When the pressure-sensitive sensor detects a defect and triggers an audible and visual alarm or the electrode detection mechanism discovers a problem, the present invention can guide the products along one side of the movable baffle into the discharge trough on the side for recycling defective products. The detected defective products can be automatically and quickly sorted out from the main conveying path and fall into the corresponding defective product recovery trough through a specific discharge trough or transmission trough, thereby realizing efficient and automatic separation of good products and defective products and improving overall production efficiency and sorting accuracy.

As the correction conveying roller 5 moves in a circle, the battery can be clamped inside the correction conveying roller 5. During the conveying process, with the cooperation of the movable insertion rod 581 and the pressure-sensitive sensor 58, the battery with pit defects on the surface can be detected, and the defective products can be sorted out, thereby reducing the defective product rate in subsequent production.

The buffer rack 35 is composed of a group of bending plates and fixed plates arranged in parallel, and the fixed plate is arranged at an angle to fit on the guide plate 32. The guide plate 32 is used for battery feeding and transmission, and the buffer rack 35 is used for buffering to reduce surface depression caused by collision during transportation. The buffer rack 35 can be against the bottom of the guide plate 32, which can shorten the drop distance of the battery after loading, and can effectively reduce the depression of the battery caused by external force during transmission.

[0041] An arc-shaped adsorption baffle 38 is installed inside the buffer rack 35, and several adsorption sheets 381 are arranged inside the adsorption baffle 38. Adhesive plates are provided on both sides of the adsorption sheet 381. A toggle plate 382 is connected to the outer wall of the adsorption baffle 38. Several chip grooves 351 are provided on the fixed plate of the buffer rack 35, and a rectangular groove connected to the fixed screen plate is provided on the top of the buffer rack 35. During the continuous feeding and conveying of batteries, the debris and dust entrained therein can enter the gap of the buffer rack 35 along the chip groove 351 and the fixed screen plate, and as the battery continues to knock on the buffer rack 35, the dust on one side of the adsorption baffle 38 can be accumulated on the adhesive plates on both sides of the adsorption sheet 381, which is convenient for subsequent unified cleaning.

[0042] like Figure 5 and Figure 6As shown, a clamping shaft 36 is installed inside the feeding rack 3, and a plurality of reset plates 362 are provided on the top of the clamping shaft 36. A plurality of straight grooves corresponding to the reset plates 362 are opened on the buffer rack 35. The reset plates 362 are against the toggle plates 382 during the swinging process. As the batteries are fed, the reset plates 362 are driven to move. Under the action of the toggle plates 382, ​​the adsorption baffle 38 can be pulled to move, and dust can be evenly accumulated inside the adsorption baffle 38.

[0043] Several arc-shaped pressure plates 361 are provided at the bottom of the clamping shaft 36. The arc-shaped pressure plates 361 are arc-shaped and located on the outside of the correction conveying roller 5. They are used to press the battery into the correction groove. A rubber gasket is provided inside the arc-shaped pressure plate 361, which is used to drive the battery to rotate inside the correction groove during the circular motion of the correction conveying roller 5. The battery can be stuck inside the correction groove. As the correction conveying roller 5 rotates and the arc-shaped pressure plate 361 is squeezed, the battery can be pressed into the correction groove. The movable insertion rods 581 on both sides can be against the outer wall of the battery. During the circular motion of the correction conveying roller 5, the battery can complete circular rotation inside the correction groove under the friction of the rubber gasket at the bottom of the arc-shaped pressure plate 361.

[0044] like Figure 8 As shown, a plurality of elastic pads 551 are provided on the limiting shaft 55. The elastic pads 551 are arranged in a uniform array on the limiting shaft 55. The circumferential rotation of the battery can rub against the surface of the elastic pads 551 to clean the excess dust, etc., and enter the circular groove on the surface of the dust collection tube 52 along with the air flow.

[0045] A circular groove is provided on the correction conveyor roller 5, and the circular groove is connected to the correction groove. A number of rubber sheets 56 connected to the bottom of the correction groove are provided inside the correction conveyor roller 5. The mesh sheet 53 can be squeezed with the rubber sheet 56 inside the correction conveyor roller 5 during the circular motion, and can squeeze the dust and debris during the deformation process so that it is adsorbed inside the mesh sheet 53.

[0046] like Figure 9 As shown, the pressure-sensitive sensor 58 is provided with a group of docking tubes, and a movable rod 581 is inserted inside the docking tube. The top of the movable rod 581 is against the outer wall of the battery, and the bottom of the movable rod 581 is provided with a buffer pad for abutting against the receiving end of the pressure-sensitive sensor 58. An audible and visual alarm is provided inside the connecting plate 57. When the movable rod 581 is pressed and the battery rotates, the pressure change is too large and the audible and visual alarm can play a predictive role. In the process of correcting the circular motion of the conveying roller 5, the battery can complete the circular rotation inside the correction groove under the friction of the rubber pad at the bottom of the arc-shaped pressure plate 361. With the cooperation of the movable rod 581, the outer roundness of the battery is detected. When encountering a battery with a concave surface, the pressure change that can be received by the pressure-sensitive sensor 58 is larger, and the audible and visual alarm is activated at this time.

[0047] like Figure 7 As shown, a sealing plate 51 is connected to the outside of the dust suction tube 52, and a guide groove that passes through the external equipment is provided on the sealing plate 51. A number of arc-shaped depressions are provided on the outside of the dust suction tube 52, and an elastic mesh sheet 53 is provided inside the arc-shaped depression. The position of the mesh sheet 53 corresponds to the position of the rubber sheet 56. The mesh sheet 53 is used for unified collection of dust to facilitate subsequent disassembly and cleaning.

[0048] like Figure 2 As shown, the electrode detection mechanism 4 includes a slide plate and a control cylinder 41, and the slide plate is installed on the top of the connecting base 1, and the control cylinder 41 is movably set on the top of the slide plate. A pair of discharge grooves are opened on the connecting base 1, which are respectively located at the bottom of the feed rack 3 and the electrode detection mechanism 4, and a transmission groove corresponding to one side of the discharge groove is opened on the slide plate. A group of conveying rods connected to the detection plate are provided on one side of the control cylinder 41 for detecting the position of the electrode;

[0049] A docking plate 31 is provided on one side of the bottom of the feed rack 3, and a movable baffle 311 is interactively provided inside the docking plate 31 for exporting defective batteries, and an arc-shaped baffle 42 is connected to one side of the slide plate. When the sound and light alarm is running, the movable baffle 311 moves, and the control cylinder 41 can also move, and the battery can fall onto the guide plate, and with the cooperation of the arc-shaped baffle 42, it falls into the recovery tank on the side for collecting defective products.

[0050] like Figure 3 As shown, a buffer baffle 34 is provided on the top of the blocking plate 33. The cross section of the buffer baffle 34 is "U"-shaped. The buffer baffle 34 can play a buffering role and can reduce the situation where the battery moves along the blocking plate 33 to the outside of the feed rack 3.

[0051] like Figure 4 As shown, a group of rectangular movable frames 21 are inserted at the top of the feeding track 2, and a positioning plate 22 is connected to the top of the group of movable frames 21. A rotating ring 23 is rotatably provided on the positioning plate 22, and a threaded groove is provided inside the rotating ring 23. The top of the feeding track 2 is connected to a threaded rod inserted inside the rotating ring 23. The position of the rotating ring 23 on the threaded rod is adjusted according to the different sizes of batteries, so that the gap distance between the bottom of the movable frame 21 and the inside of the feeding track 2 can be adjusted, and the battery can be controlled to be fed evenly inside the feeding track 2, reducing the situation where the gap is too large and the internal jamming occurs.

[0052] Working principle: First, when the battery needs to be conveyed, as the battery is fed along the feeding track 2, the battery can be conveyed to the inside of the feeding rack 3, and the battery can be evenly clamped inside the correction groove. As the correction conveying roller 5 moves in a circle, the battery can be clamped inside the correction conveying roller 5. During the conveying process, with the cooperation of the movable insertion rod 581 and the pressure-sensitive sensor 58, the battery with pit defects on the surface can be detected, and the defective products can be removed, thereby reducing the defective product rate in subsequent production. During the feeding process, the position of the rotating ring 23 on the threaded rod can be adjusted according to the different sizes of batteries, and the gap distance between the bottom of the movable rack 21 and the inside of the feeding track 2 can be adjusted. The battery can be controlled to feed evenly inside the feeding track 2, reducing the situation where the gap is too large and causes internal jamming.

[0053] Then, during the battery feeding process, the debris remaining on the surface can fall along the chip removal groove 351 and the grid plate to the side of the adsorption baffle 38. With the vibration of the battery feeding, the dust and debris can be accumulated on both sides of the adsorption sheet 381, and adsorbed with the help of adhesive, which is convenient for subsequent unified processing and replacement. The battery slides along the reset plate 362 to the side of the correction conveyor roller 5, and can be stuck in the correction groove. With the rotation of the correction conveyor roller 5 and the extrusion of the arc-shaped pressure plate 361, the battery can be pressed into the correction groove, and the movable insertion rods 581 on both sides can be pressed against the outer wall of the battery. During the circular motion of the correction conveying roller 5, the battery can complete circular rotation inside the correction groove under the friction of the rubber pad at the bottom of the arc-shaped pressure plate 361. Under the cooperation of the movable insertion rod 581, the outer roundness of the battery is detected. When encountering a battery with a concave surface, the pressure change received by the pressure-sensitive sensor 58 is relatively large. At this time, the sound and light alarm is activated, and the movable baffle 311 is activated, and the control cylinder 41 can also be activated. The battery can fall onto the guide plate and, under the cooperation of the arc baffle 42, fall into the recovery tank on the side where defective products are collected.

[0054] Finally, when the external equipment is sucking air, the negative pressure can be sucked inside the vacuum tube 52, and the circular rotation of the battery can rub and clean the surface of the elastic pad 551, scraping off excess dust and the like, and entering the circular groove on the surface of the vacuum tube 52 with the air flow, and the mesh sheet 53 can be squeezed against the rubber sheet 56 inside the correction conveying roller 5 during the circular motion, and can squeeze the dust debris during the deformation process, so that it is adsorbed inside the mesh sheet 53.
