Description

Technical Field

[0001] The present application relates to the field of battery casing production equipment, and in particular to a battery casing screening device. Background Art

[0002] Common batteries are cylindrical. A cylindrical dry cell usually includes a cylindrical battery shell and internal positive and negative fillings. One end of the battery shell is closed, and a cover is installed on the other end. A metal needle is provided on the cover. The metal needle is inserted into the filling inside the battery to guide the movement of electrons in the filling.

[0003] Dry cell batteries are typically mass-produced on assembly lines. Therefore, prior to production, the metal housings of the dry cells need to be aligned so that the openings of the battery housings face the same direction. This alignment is typically done using a multi-track vibrating plate. However, the plate only aligns the cylindrical battery housings into a parallel position, leaving the openings of the battery housings facing different directions. Therefore, the alignment of the battery housings using the plate requires alignment of the openings so that they all face the same direction.

[0004] A common solution is to install a barb rotatably above the track of the vibration disk, with the rotation plane of the barb being vertical. If the open end of the battery shell moving along the vibration disk faces the barb, the barb will hook on the open end of the battery shell when the battery shell passes the barb. As the rear battery shell moves forward, it pushes the front battery shell to continue moving forward. The battery shell hooked on the barb will flip over under the guidance of the barb, completing the reversal of the closed end and the open end of the battery shell, so that the open ends of the battery shells on the track of the vibration disk are all oriented in the same direction.

[0005] However, the above technology is only applicable to battery casings with a small aspect ratio. When the aspect ratio of the battery casing is large, during the process of flipping the battery casing by the barb, the battery casing may not be flipped due to its excessive length, or the battery casing may tilt during the flipping process due to its excessive length, so that the flipped battery casing may slide off the track, making the combing effect of the battery casing with a large aspect ratio by the barb poor. A more suitable technology is needed to comb the opening direction of the battery casing with a large aspect ratio. Summary of the Invention

[0006] In order to solve the problem of poor combing effect of combing battery casings with a large aspect ratio on a vibration plate by using barbs, the present application provides a battery casing screening device.

[0007] The battery shell screening device provided in this application adopts the following technical solution:

[0008] A battery shell screening device comprises a vibrating plate and a transport track, wherein the transport track is installed on the vibrating plate, and the transport track spirals around the side wall of the vibrating plate toward the bottom of the discharge port of the vibrating plate, and the transport track is used to cooperate with the vibrating plate to comb and transport battery shells, and a screening port is provided on the side wall of the curved section of the transport track, and a push rod is rotatably installed on the transport track, and the rotating surface of the push rod is vertical, and the free end of the push rod extends to the screening port and a guide is provided on the free end of the push rod, and the minimum distance between the free end of the push rod and the bottom of the transport track is less than the diameter of the battery shell, and the guide is used to guide the battery shell to push the push rod to rotate, and the vibrating plate is provided with a recovery mechanism for recovering the battery shells that fall from the screening port.

[0009] By adopting the above technical solution, when the vibration plate pushes the battery shell to move on the transport track to the screening port, the push rod generates resistance to the battery shell through the guide member, and the end of the battery shell facing away from the push rod will pass through the screening port and be outside the transport track due to the resistance of the push rod. Since the transport track is inclined downward, if the end of the battery shell outside the transport track is the closed end of the battery shell, the weight of the part of the battery shell outside the transport track will be greater than the weight of the part of the battery shell inside the transport track, and the battery shell will pass through the screening port and fall from the transport track. On the contrary, the battery shell will not fall from the transport track, and the battery shell will be pushed upward by the guide member under the action of the vibration plate, and then re-enter the closed section of the transport track, and then be transported to the discharge end of the transport track for discharge, thereby completing the screening of the battery shells in the vibration plate; and during the screening process of the battery shells, the battery shells in the correct direction are not easy to fall off the transport track, the screening efficiency is high, and battery shells of different models can be screened quickly and stably.

[0010] Optionally, the distances from both ends of the push rod to the bottom of the transport track are different, the end of the push rod with a larger distance from the bottom of the transport track is rotatably connected to the transport track, the other end of the push rod is a free end, and the distance between the free end of the push rod and the bottom of the transport track is smaller than the diameter of the battery casing transported on the transport track.

[0011] By adopting the above technical solution, after the battery casing on the transport track is pushed by the guide member to rotate the push rod, after the battery casing as a whole passes through the free end range of the push rod, there is no contact between the battery casing and the push rod, that is, the transport speed of the battery casing is restored to normal at this time, and the reduction range of the battery casing transport speed is small, which further improves the overall screening efficiency.

[0012] Optionally, the guide member includes a guide rod, which is curved and used to guide the battery housing to push the push rod to rotate. One end of the guide rod is coaxially connected to the free end of the push rod, and the guide rod is curved in a direction away from the ground.

[0013] By adopting the above technical solution, when the battery casing moves on the transport track, the push rod can be pushed to rotate by the curved guide rod. Due to the guidance of the guide rod, when the battery casing pushes the push rod to rotate, the battery casing is not likely to get stuck with the push rod, causing the overall transportation of the battery casing to be interrupted.

[0014] Optionally, the guide rod and the push rod are both tubular, and a resistance adjustment mechanism is provided on the transport track, and the resistance adjustment mechanism is used to adjust the size of the rotational resistance of the push rod.

[0015] By adopting the above technical solution, the tubular guide rod and push rod are lighter in weight, and the resistance of the push rod can be adjusted by cooperating with the lighter guide rod and push rod and the resistance adjustment mechanism, thereby screening battery casings of different models and specifications.

[0016] Optionally, the resistance adjustment mechanism includes a mounting frame, a spring and an adjusting rod, the mounting frame is installed on the transport track, one end of the spring is sleeved on one end of the adjusting rod and connected to the adjusting rod, the adjusting rod is vertically slidably installed on the mounting frame, the other end of the spring is pressed against the upper side of the push rod, and an adjusting ring is also rotatably installed on the mounting frame, the upper end of the adjusting rod passes coaxially through the adjusting ring, and the adjusting ring is threadedly connected to the adjusting rod.

[0017] By adopting the above technical solution, rotating the adjustment ring can drive the adjustment rod to move, thereby compressing or loosening the spring. By adjusting the elastic force of the spring, the resistance of the overall resistance adjustment mechanism to the push rod can be adjusted. The adjustment is relatively convenient and has high precision.

[0018] Optionally, a pressing plate is provided on one end of the spring facing away from the adjusting rod, and the pressing plate is arc-shaped and fits tightly against the upper side wall of the adjusting rod.

[0019] By adopting the above technical solution, the spring is pressed against the push rod through the arc-shaped pressing plate, so that the connection between the spring and the push rod is more stable.

[0020] Optionally, the pressing plate is pressed against a side wall of one end of the push rod that is rotatably connected to the mounting bracket.

[0021] By adopting the above technical solution, when the battery casing pushes the push rod to rotate, the lever principle is used, so that the battery casing can push the push rod to rotate with a smaller force. Therefore, the spring can be set to be harder, making it less likely for the spring to twist when compressed. At the same time, because the thrust of the battery casing on the push rod is amplified, it is easier to adjust the resistance applied by the spring to the push rod.

[0022] Optionally, the resistance adjustment mechanism includes an adjustment block, two baffles are provided at one end of the push rod connected to the guide rod, the space between the two baffles is independent, and the space enclosed by the two baffles is defined as an adjustment cabin, and a placement hole is provided on the upper side wall of the push rod between the two baffles, and the adjustment block can be placed into the adjustment cabin through the placement hole.

[0023] By adopting the above technical solution, the resistance of the push rod can be adjusted by placing an adjustment block in the adjustment cabin, which is convenient to adjust. Moreover, the adjustment cabin is arranged at the free end of the push rod, and the resistance of the push rod to the battery housing is relatively stable.

[0024] Optionally, the recycling mechanism includes a guide plate and a recycling box, the guide plate is mounted on the vibrating plate and is located below the transport track, the guide plate is inclined, the vertical projection of the curved section of the transport track where the screening port is located is located on the higher end of the guide plate, the recycling box is placed on the ground and is provided with an upper opening, and the lower end of the guide plate is diffracted to directly above the upper opening of the recycling box.

[0025] By adopting the above technical solution, the battery shell falling from the transport track will fall on the guide plate, and then slide along the guide plate into the recycling box to be recycled. The structure is simple and the recycling is convenient.

[0026] Optionally, the cross section of the guide plate is arc-shaped, and the diameter of the discharge end of the guide plate is smaller than the diameter of one end of the guide plate located on the transport track.

[0027] By adopting the above technical solution, the arc-shaped guide plate makes it difficult for the battery housing sliding on the guide plate to slide off the guide plate.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. When the vibration plate pushes the battery shell to move on the transport track to the screening port, the push rod generates resistance to the battery shell through the guide. The end of the battery shell facing away from the push rod will pass through the screening port and be outside the transport track due to the resistance of the push rod. If the end of the battery shell outside the transport track is the closed end of the battery shell, the weight of the part of the battery shell outside the transport track will be greater than the weight of the part of the battery shell inside the transport track, and the battery shell will pass through the screening port and fall from the transport track. Conversely, the battery shell will be pushed upward by the guide under the action of the vibration plate, and then re-enter the closed section of the transport track, and then be transported to the discharging end of the transport track for discharge, thereby completing the screening of the battery shells in the vibration plate. In addition, during the screening process, the battery shells in the correct direction are not easy to fall off the transport track, so the screening efficiency is high, and battery shells of different models can be screened quickly and stably.

[0030] 2. The tubular guide rod and push rod are light in weight, and the resistance of the push rod can be adjusted by cooperating with the light guide rod and push rod and the resistance adjustment mechanism, thereby being able to screen battery shells of different models and specifications;

[0031] 3. Turning the adjustment ring can drive the adjustment rod to move, thereby compressing or loosening the spring. By adjusting the elastic force of the spring, the resistance of the overall resistance adjustment mechanism to the push rod can be adjusted. The adjustment is more convenient and has higher precision. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0037] The following is combined with Figure 1-3 This application is described in further detail.

[0038] The present application discloses a battery shell screening device, referring to Figure 1 and Figure 2 , comprising a vibrating plate 1 placed on the ground and a transport track 2 fixedly mounted on the side wall of the vibrating plate 1, one end of the transport track 2 is fixedly connected to and communicates with the discharge end of the vibrating plate 1, and the other end of the transport track 2 extends around the side wall of the vibrating plate 1, and the extension direction of the transport track 2 is toward the bottom of the discharge end of the vibrating plate 1. The transport track 2 of this embodiment has three tracks, and the transport track 2 can also be designed as a double track, a single track, or other track number.

[0039] Reference Figure 1 and Figure 2 A screening port 21 is provided on the side wall of the curved section of the transport track 2, which is away from the vibration plate 1. The battery casings output from the vibration plate 1 can pass through the screening port 21 and fall off the transport track 2. A push rod 22 is rotatably mounted on the transport track 2. The rotation plane of the push rod 22 is vertical. The free end of the push rod 22 extends to the screening port 21 and a guide is provided on the free end of the push rod 22. The guide includes a guide rod 3, one end of which is coaxially fixed to the free end of the push rod 22. Both the push rod 22 and the guide rod 3 are tubular. The guide rod 3 is curved, and the protrusion of the guide rod 3 faces the bottom of the transport track 2. The battery casing sliding on the transport track 2 pushes the guide rod 3 and then pushes the push rod 22 to rotate.

[0040] Reference Figure 1 and Figure 2 In the initial state, the push rod 22 is inclined toward the bottom of the transport track 2, and the distance between the free end of the push rod 22 and the transport track 2 is smaller than the diameter of the battery housing.

[0041] Reference Figure 1 and Figure 2 A resistance adjustment mechanism 4 is also provided on the transport track 2. The first type of resistance adjustment mechanism 4 includes a mounting bracket 41, a spring 42, and an adjustment rod 43. The mounting bracket 41 is fixedly mounted on the transport track 2, and the adjustment rod 43 is slidably mounted on the mounting bracket 41. An adjustment ring 44 is also rotatably mounted on the mounting bracket 41. One end of the adjustment rod 43 coaxially passes through the adjustment ring 44 and is threadedly engaged with the adjustment ring 44. Rotation of the adjustment ring 44 drives the adjustment rod 43 to slide. One end of the spring 42 is fixedly connected to one end of the adjustment rod 43, and the other end of the spring 42 is fixedly connected to an arc-shaped abutting plate 45. The abutting plate 45 abuts against the side wall of the upper side of the end of the push rod 22 that is rotatably connected to the mounting bracket 41.

[0042] Reference Figure 1 and Figure 2The sliding direction of the adjusting rod 43 is parallel to the expansion and contraction direction of the spring 42 . The spring 42 can be compressed by sliding the adjusting rod 43 , thereby adjusting the resistance of the push rod 22 to the battery casing transported on the transport track 2 .

[0043] Reference Figure 1 and Figure 2 For different types of battery shells, by rotating the adjusting ring 44 to drive the adjusting rod 43 to slide and adjust the elastic force of the spring 42 to the appropriate size, the vibration plate 1 can be started to transport the battery shell. When the battery shell moves along the transport track 2 to the screening port 21, the guide rod 3 will press against one end of the battery shell and apply resistance to the battery shell. One end of the battery shell will pass through the screening port 21 and be outside the transport track 2 under the mutual cooperation of the thrust, gravity and resistance of the vibration plate 1.

[0044] Reference Figure 1 and Figure 2 Since one end of the battery shell is closed and an electrode needle is installed in the closed end, the weight of the two ends of the battery shell is different. When the closed end of the battery shell passes through the transport track 2, the weight of the part of the battery shell located inside the transport track 2 will be less than the weight of the part of the battery shell located outside the transport track 2. The battery shell will pass through the screening port 21 as a whole and fall from the transport track 2, completing the screening of the battery shell.

[0045] Reference Figure 1 and Figure 2 On the contrary, if one end of the battery shell located in the screening track is a closed end, the battery shell will be pushed by the guide rod 3 to rotate the push rod 22 under the action of gravity and the thrust of the vibrating plate 1, and then enter the closed section of the transport track 2 to continue to be transported to the discharge end of the transport track 2 for discharge. Moreover, since the push rod 22 is inclined, the push rod 22 will not generate resistance to the battery shell after the battery shell passes the lower end of the push rod 22, and the reduction in the transportation speed of the battery shell is small, and it is not easy for the battery shells to be blocked by each other head and tail.

[0046] Reference Figure 3 The second resistance adjustment mechanism 4 includes a plurality of adjustment blocks 46 and an adjustment cabin 5 arranged inside the push rod 22. The adjustment cabin 5 is formed by two baffles 47 enclosed inside the push rod 22. A placement hole 221 is opened on the side wall on the upper side of the push rod 22. The placement hole 221 is connected to the adjustment cabin 5. The resistance of the push rod 22 can be adjusted by placing the adjustment block 46 into the adjustment cabin 5 through the placement hole 221.

[0047] Reference Figure 1 and Figure 2A recovery mechanism 6 is also provided on the vibrating plate 1. The recovery mechanism 6 includes an arc-shaped guide plate 61 and a recovery box 62 with an upper opening. The arc-shaped guide plate 61 is fixedly mounted on the vibrating plate 1 at an angle, and the vertical projection of a section of the transport track 2 with the screening port 21 is located above the upper end of the guide plate 61. The recovery box 62 is placed on the ground, and the lower end of the guide plate 61 extends directly above the recovery box 62. The battery shells that have been screened slide along the guide plate 61 and fall into the recovery box 62 for recycling. At the same time, the diameter of the lower end of the guide plate 61 is smaller than the diameter of the upper end of the guide plate 61, so that the battery shells poured out of the guide plate 61 fall more centrally and are less likely to fall outside the recovery box 62.

[0048] The implementation principle of a battery shell screening device in an embodiment of the present application is as follows: after the vibration disk 1 is started, the battery shells in the vibration disk 1 are sorted and output to the transport track 2 along the track inside the vibration disk 1, and then move along the transport track 2 until the screening port 21, and the push rod 22 and the guide rod 3 to which resistance is applied by the resistance adjustment mechanism 4 apply resistance to the battery shell, and the end of the battery shell facing away from the guide rod 3 will pass through the screening port 21 and be located outside the transport track 2. At this time, if the end of the battery shell that is tightly pressed against the guide rod 3 is an open end, then due to the heavier weight of the end located outside the transport track 2, the battery shell will fall from the transport track 2 onto the guide plate 61, and then slide along the guide plate 61 to the recycling box 62 for recycling. Otherwise, the battery shell will be pushed by the guide rod 3 to rotate the push rod 22, and the battery shell will move back to the closed section of the transport track 2 until it moves to the discharge end of the transport track 2 for discharge.

[0049] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
