Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary equipment for appearance detection of soft-pack batteries, in particular to an auxiliary mechanism for battery detection. Background Technique

[0002] With the development demand of electronic application devices, the lithium battery industry has also witnessed rapid development. Many lithium battery manufacturers have emerged and grown rapidly. During the battery production process, appearance detection is an important test to check whether the battery is qualified. Many surface defects of lithium batteries are directly related to the internal and external structural defects of the battery. These defects will directly cause safety problems and reliability problems of the battery. By detecting surface defects, a large part of important potential safety hazards can be effectively eliminated. Therefore, the detection of surface defects is very important. At present, when detecting the appearance of soft-pack batteries, it is not easy to detect the bottom of the soft-pack battery located on the conveying mechanism during the conveying and detection process. At this time, a turning structure is needed.

[0003] At present, during the process of turning the soft-pack battery with the existing turning structure for soft-pack batteries, the soft-pack battery is likely to cause a certain impact on the turning structure. When the impact force on the soft-pack battery is too large, the soft-pack battery is easily damaged, increasing the unqualified rate of the soft-pack battery. For this reason, we propose an auxiliary mechanism for battery detection to solve the existing problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide an auxiliary mechanism for battery detection to solve the problems put forward in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: An auxiliary mechanism for battery detection includes a cuboid-shaped rotating plate. The center positions of the outer walls at both ends of the cuboid-shaped rotating plate are both equipped with connecting shafts. The other end of the connecting shaft on one end of the cuboid-shaped rotating plate is installed in the bearing on the outer wall of the second side plate. The other end of the connecting shaft on the other end of the cuboid-shaped rotating plate passes through the bearing on the outer wall of the first side plate and is connected to a stepping motor through a coupling. Third connecting plates are installed around the outer surface of the cuboid-shaped rotating plate. Both sides of the third connecting plate are connected to the second connecting plate through pressure detection sensors. The second connecting plate is connected to the first connecting plate through a buffer mechanism. A rubber soft plate is installed on the other side surface of the first connecting plate. Installation plates are installed at the bottom ends of the first side plate and the second side plate. Hydraulic telescopic rods are installed on both sides of the lower surface of the installation plate. The bottom ends of the hydraulic telescopic rods are installed on the top ends of hydraulic cylinders. The conveying hydraulic cylinder is installed on the upper surface of the base. The stepping motor is installed on the upper surface of a support plate. The support plate is installed on one side outer wall of the first side plate.

[0006] Through the coordinated setting of a series of structures, when the staff needs to turn over the soft-pack battery, the staff places the present utility model between adjacent conveying structures and starts the hydraulic cylinder. The hydraulic telescopic rod expands and contracts, and the staff adjusts the horizontal height of the cuboid-shaped rotating plate, so as to match conveying structures of different heights. When the conveying structure conveys the soft-pack battery onto the rubber soft plate, the pressure detection sensor will detect that the pressure data value changes within a certain range. At this time, the controller controls the stepping motor to work. The stepping motor indirectly drives the cuboid-shaped rotating plate to rotate. The rotation of the cuboid-shaped rotating plate can indirectly drive the soft-pack battery to rotate and turn over and slide onto another conveying structure. Thus, the present utility model facilitates the turning over of the soft-pack battery during the conveying and detection process, avoiding the situation that the bottom of the soft-pack battery located on the conveying mechanism during the conveying and detection process cannot be effectively detected, improving the appearance detection effect of the soft-pack battery. Through the coordinated setting of a series of structures such as the buffer mechanism and the rubber soft plate, when the soft-pack battery is conveyed onto the rubber soft plate, the rubber soft plate can play a certain protective role for the soft-pack battery, avoiding the occurrence of scratches on the outer surface of the soft-pack battery. The setting of the buffer mechanism, when the soft-pack battery is conveyed onto the rubber soft plate, the coordinated setting of a series of structures such as the spring and the damping rubber plate on the buffer mechanism can play a buffering role, reducing the impact force received by the soft-pack battery, thus avoiding the situation that the soft-pack battery is damaged due to excessive impact force, improving the qualified rate of the soft-pack battery, and having strong practicability.

[0007] Preferably, fixing plates are obliquely and fixedly connected to both sides of the rubber soft plate. An activity plate is movably connected to the surface of the fixing plate facing the middle position of the rubber soft plate. A chute is formed on one side of the surface of the activity plate, and a clamping plate is slidably connected through the chute. Sliders located inside the chute are arranged on one side of the surface of the clamping plate, and rubber pads are coated on the outer circumferences of the sliders.

[0008] Preferably, the buffer mechanism includes a first connecting column, a convex block, a damping rubber plate, a strip-shaped slot, a spring, a second connecting column, a pressing plate and a mounting groove. The second connecting columns at both ends of the buffer mechanism are respectively connected to one side surfaces of the first connecting plate and the second connecting plate. An installation groove is formed at the center position of the end wall of the first connecting column, and a spring is installed in the installation groove.

[0009] Preferably, pressing plates are installed at both ends of the spring, and there is a clearance connection between the outer wall of the pressing plate and the groove wall of the installation groove. A second connecting column is installed on the other side surface of the pressing plate. Convex blocks are installed on both outer walls of the pressing plate, and the other ends of the convex blocks are installed in the strip-shaped slot, and there is a clearance connection between the outer wall of the convex block and the hole wall of the strip-shaped slot.

[0010] Preferably, the strip-shaped slot holes are opened on both sides of the groove wall of the installation groove. A damping rubber plate is installed in the strip-shaped slot holes, and one outer wall of the damping rubber plate is attached to one outer wall of the bump.

[0011] Preferably, a display screen and a control panel are arranged on the end face of the control box, and the display screen is located above the control panel. Control buttons are arranged on the control panel, and an analog-to-digital conversion module and a controller are arranged inside the control box.

[0012] Preferably, the output end of the pressure detection sensor is electrically connected to the input end of the analog-to-digital conversion module, the output end of the analog-to-digital conversion module is electrically connected to the input end of the controller, and the output end of the controller is respectively electrically connected to the input ends of the display screen, the stepping motor, and the hydraulic cylinder.

[0013] Preferably, screw holes are opened at the central positions inside the fixing plates. The fixing plates are screwed to bolts through the screw holes, and the ends of the bolts extend into the movable plates. Buffer pads are wrapped around the outer peripheries of the clamping blocks.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] 1. Through the cooperation of a series of structures in the present utility model, when the staff needs to turn over the soft-pack battery, the staff places the present utility model between adjacent conveying structures, starts the hydraulic cylinder, the hydraulic telescopic rod expands and contracts, and the staff adjusts the horizontal height of the cuboid-shaped rotating plate, so as to match conveying structures of different heights. When the conveying structure conveys the soft-pack battery onto the rubber soft plate, the pressure detection sensor will detect that the pressure data value changes within a certain range. At this time, the controller controls the stepping motor to work, and the stepping motor indirectly drives the cuboid-shaped rotating plate to rotate. The rotation of the cuboid-shaped rotating plate can indirectly drive the soft-pack battery to rotate and turn over and slide onto another conveying structure. Therefore, the present utility model is convenient for turning over the soft-pack battery during the conveying and detection process, avoiding the situation that the bottom of the soft-pack battery located on the conveying mechanism cannot be effectively detected during the conveying and detection process, and improving the appearance detection effect of the soft-pack battery.

[0016] 2. Through the cooperation of a series of structures such as the buffer mechanism and the rubber soft plate in the present utility model, when the soft-pack battery is conveyed onto the rubber soft plate, the rubber soft plate can play a certain protective role for the soft-pack battery, avoiding the occurrence of scratches on the outer surface of the soft-pack battery. With the setting of the buffer mechanism, when the soft-pack battery is conveyed onto the rubber soft plate, the cooperation of a series of structures such as the spring and the damping rubber plate on the buffer mechanism can play a buffering role, reducing the impact force received by the soft-pack battery, thereby avoiding the situation that the soft-pack battery is damaged due to excessive impact force, improving the qualified rate of the soft-pack battery, and having strong practicability.

[0017] 3. A buffer assembly is provided between adjacent rubber flexible plates of the present utility model. When the soft-pack battery is conveyed onto the surface of the rubber flexible plate, its two sides will be clamped between the clamping plates. When it is flipped, as the soft-pack battery flips, its two sides will drive the sliders to slide along the sliding grooves. A rubber pad structure is provided between the outer periphery of the slider and the inner wall of the sliding groove, which can increase the frictional resistance, thereby reducing the flipping speed of the soft-pack battery during the flipping process, playing a further buffering role, and avoiding the problem of damage caused by the soft-pack battery flipping too quickly during the flipping process. By screwing the bolt along the screw hole, the position of the movable plate and the distance between the clamping plates can be adjusted, thereby meeting the flipping requirements of soft-pack batteries of different specifications.

[0025] The technical solution of the present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0026] Embodiment 1

[0027] As Figures 1-6 shown, an auxiliary mechanism for battery detection proposed by the present utility model includes a rectangular parallelepiped-shaped rotating plate 1. Connecting shafts 15 are installed at the central positions of the outer walls at both ends of the rectangular parallelepiped-shaped rotating plate 1. The other end of the connecting shaft 15 on one end of the rectangular parallelepiped-shaped rotating plate 1 is installed in a bearing on the outer wall of the second side plate 14. The other end of the connecting shaft 15 on the other end of the rectangular parallelepiped-shaped rotating plate 1 passes through a bearing on the outer wall of the first side plate 2 and is connected to a stepping motor 4 through a coupling 3. Third connecting plates 21 are installed around the outer surface of the rectangular parallelepiped-shaped rotating plate 1. Both side surfaces of the third connecting plate 21 are connected to the second connecting plate 18 through pressure detection sensors 20. The second connecting plate 18 is connected to the first connecting plate 17 through a buffer mechanism 19. A rubber soft plate 16 is installed on the other side surface of the first connecting plate 17. Mounting plates 6 are installed at the bottoms of the first side plate 2 and the second side plate 14. Hydraulic telescopic rods 7 are installed on both sides of the lower surface of the mounting plate 6. The bottom end of the hydraulic telescopic rod 7 is installed at the top end of a hydraulic cylinder 8. The conveying hydraulic cylinder 8 is installed on the upper surface of a base 9.

[0028] The working principle of the auxiliary mechanism for battery detection based on Embodiment 1 is as follows: During use, when the external power supply is connected and the staff needs to turn over the soft-pack battery, the staff places the present utility model between adjacent conveying structures. Then the staff starts the hydraulic cylinder 8, and the hydraulic telescopic rod 7 expands and contracts. The staff adjusts the horizontal height of the cuboid-shaped rotating plate 1, so as to match conveying structures of different heights. When the conveying structure conveys the soft-pack battery onto the rubber soft plate 16, the pressure detection sensor 20 will detect that the pressure data value changes within a certain range. At this time, the controller controls the stepper motor 4 to work. The stepper motor 4 indirectly drives the cuboid-shaped rotating plate 1 to rotate. The rotation of the cuboid-shaped rotating plate 1 can indirectly drive the soft-pack battery to rotate and turn over and slide onto another conveying structure. Thus, the present utility model facilitates the turning over of the soft-pack battery during the conveying and detection process, avoiding the situation that the bottom of the soft-pack battery located on the conveying mechanism during the conveying and detection process cannot be effectively detected, improving the appearance detection effect of the soft-pack battery. When the soft-pack battery is conveyed onto the rubber soft plate 16, the rubber soft plate 16 can play a certain protective role for the soft-pack battery, avoiding the occurrence of scratches on the outer surface of the soft-pack battery. The setting of the buffer mechanism 19, when the soft-pack battery is conveyed onto the rubber soft plate 16, the cooperation of a series of structures such as the spring 1905 and the damping rubber plate 1903 on the buffer mechanism 19 can play a buffering role, reducing the impact force received by the soft-pack battery, thus avoiding the situation that the soft-pack battery is damaged due to excessive impact force, improving the qualified rate of the soft-pack battery, and having strong practicability.

[0030] Such as Figures 1-6As shown in the figure, an auxiliary mechanism for battery detection proposed by the present utility model. Compared with the first embodiment, this embodiment further includes: a stepping motor 4 is installed on the upper surface of a support plate 5, and the support plate 5 is installed on the outer wall of one side of a first side plate 2. A buffer mechanism 19 includes a first connecting column 1901, a convex block 1902, a damping rubber plate 1903, a strip-shaped slot hole 1904, a spring 1905, a second connecting column 1906, a pressing plate 1907, and a mounting groove 1908.

An installation groove 1908 is opened at the central position of the end wall of the first connecting column 1901. A spring 1905 is installed in the installation groove 1908. Both ends of the spring 1905 are installed with pressing plates 1907, and there is a clearance connection between the outer wall of the pressing plate 1907 and the groove wall of the installation groove 1908. The other side surface of the pressing plate 1907 is installed with a second connecting column 1906. Convex blocks 1902 are installed on both outer walls of the pressing plate 1907. The other end of the convex block 1902 is installed in the strip-shaped slot hole 1904, and there is a clearance connection between the outer wall of the convex block 1902 and the hole wall of the strip-shaped slot hole 1904. The strip-shaped slot hole 1904 is opened on both sides of the groove wall of the installation groove 1908. A damping rubber plate 1903 is installed in the strip-shaped slot hole 1904. One side outer wall of the damping rubber plate 1903 is in contact with one side outer wall of the convex block 1902. A display screen 12 and a control panel 11 are arranged on the end face of a control box 13, and the display screen 12 is located above the control panel 11. Control buttons 10 are arranged on the control panel 11. An analog-to-digital conversion module and a controller are arranged inside the control box 13. The output end of a pressure detection sensor 20 is electrically connected to the input end of the analog-to-digital conversion module. The output end of the analog-to-digital conversion module is electrically connected to the input end of the controller. The output end of the controller is respectively electrically connected to the input ends of the display screen 12, the stepping motor 4, and a hydraulic cylinder 8.

[0031] In this embodiment, since there is a clearance connection between the outer wall of the pressing plate 1907 and the groove wall of the installation groove 1908, and there is a clearance connection between the outer wall of the convex block 1902 and the hole wall of the strip-shaped slot hole 1904, it can play a role in limiting and guiding the movement of the pressing plate 1907, avoiding the situation of tilting when the pressing plate 1907 squeezes and rebounds the spring 1905, and improving the stability of the movement of the pressing plate 1907. The setting of the damping rubber plate 1903 can play a damping role and avoid the spring 1905 being in a state of rebound compression for a long time.

Screw holes 24 are formed at the central positions inside the fixed plates 22. The fixed plates 22 are screwed to bolts 25 through the screw holes 24, and the ends of the bolts 25 extend into the inside of the movable plate 23.
