Description

Technical Field

[0001] This invention belongs to the field of battery manufacturing technology, and in particular relates to a handling tool for battery grids. Background Technology

[0002] The grid is a major component of lead-acid batteries. It is rectangular in shape with a grid pattern inside and a rectangular tab on one side. It can be formed by gravity casting, stamping and other methods.

[0003] For example, Chinese invention CN113998366B discloses an auxiliary handling device for the production of battery grids. The grids are clamped and supported by two support rods on the mounting plate, and the grids are lifted by the two support rods. Since the length of the support rods and the thickness of the grids are fixed, the number of grids that are fully hung on the support rods each time is fixed, thereby avoiding the process of manually confirming the number of grids and improving the overall work efficiency.

[0004] However, in the above-mentioned existing technology, it was found that the stability of the grid cannot be guaranteed during the handling process, which often leads to the grid falling off during use by employees, resulting in low overall reliability. Summary of the Invention

[0005] The purpose of this invention is to provide a tool for handling battery grids. By pressing the pressing plate to drive the lead screw to rotate, the lead screw drives the lead screw nut to move axially, thereby using the clamping block and the mounting plate to clamp the grids being handled. This solves the problem that existing grids are prone to falling off, resulting in low overall reliability.

[0006] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: This invention relates to a handling tool for battery grids, comprising a mounting plate with two symmetrically arranged support rods connected to it, and a handle fixedly connected to the mounting plate. Each support rod has a hollow tubular structure, with a straight groove axially formed on its side wall and a circumferentially formed receiving groove. The receiving groove is located at the end of the support rod furthest from the mounting plate and communicates with the end of the straight groove. A lead screw is rotatably connected inside the support rod, and the lead screw is fitted with a nut, with a clamping block fixedly connected to the outer wall of the nut. One end of the lead screw extends into a support rod and is fixedly connected to a driven gear; the mounting plate is slidably connected to a pressing plate, and the pressing plate is fixedly connected to two racks, which mesh with two driven gears respectively. By pressing the pressing plate, the racks drive the driven gears to rotate. When the clamping block is located at the receiving slot, the lead screw drives the lead nut to rotate synchronously. When the clamping block rotates to the straight slot position, the lead screw drives the lead nut to move axially, thereby realizing the clamping of the transported grid by the cooperation of the clamping block and the mounting plate.

[0007] As a preferred embodiment of the present invention, the support rod is a flat tube structure.

[0008] As a preferred embodiment of the present invention, one end of the support rod is a closed structure, and the other end is fixedly connected to an installation block. One end of the lead screw is rotatably connected to the end wall of the support rod, and the other end is rotatably connected to the installation block and passes through the installation block. The installation block is slidably connected to the installation plate, and the installation plate has a rectangular hole through which the support rod passes to adjust the distance between the two support rods.

[0009] As a preferred embodiment of the present invention, a flat shaft is fixedly connected to the upper end of the rack, and the flat shaft is provided with external threads; the pressing plate is provided with a strip-shaped groove that is clearance-fitted with the flat shaft, the flat shaft passes through the strip-shaped groove, and is connected and fixed by a nut.

[0010] As a preferred embodiment of the present invention, the rack is a cylindrical rack, and the mounting block is fixedly connected with a plurality of ear plates, and the rack and ear plates are movably interlocked.

[0011] As a preferred embodiment of the present invention, the rack is fitted with a compression spring, which is located between the pressing plate and the ear plate, and is used to push the pressing plate to move and reset by the compression spring.

[0012] As a preferred embodiment of the present invention, the mounting plate is movably interspersed with several guide rods, and the several guide rods are fixedly connected to a clamping plate. The guide rods are fitted with springs located between the clamping plate and the mounting plate, which are used to clamp the transported grid through the clamping plate and the clamping block, and to buffer the clamping force through the springs.

[0013] In a preferred embodiment of the present invention, the mounting plate is rotatably connected to a screw nut, the screw nut is fitted with a screw, and a gear is fixedly connected to the outer wall of the screw nut; a push plate is fixedly connected to one end of the screw, the push plate has through holes that mate with guide rods, and a spring is located between the clamping plate and the push plate; a rack that meshes with the gear is fixedly connected to the pressing plate, and by pressing the pressing plate, the rack drives the screw nut to rotate, thereby driving the screw to move axially, and the push plate pushes the spring and the clamping plate, causing the clamping plate and the clamping block to move in opposite directions, thereby clamping the grid.

[0014] As a preferred embodiment of the present invention, the pressing plate is fixedly connected to an arc-shaped pressing plate, which is located above the handle.

[0015] In a preferred embodiment of the present invention, both the clamping plate and the push plate are made of nylon.

[0016] The present invention has the following beneficial effects: The present invention features a rotatable lead screw connected to the support rod. The lead screw is fitted with a lead screw nut, and a clamping block is fixedly connected to the outer wall of the lead screw nut. By pressing the pressing plate, the rack drives the driven gear to rotate, and the lead screw drives the lead screw nut to rotate synchronously. When the clamping block rotates to the straight groove position, the lead screw drives the lead screw nut to move axially. This allows the clamping block and the mounting plate to cooperate in clamping the transported grid, thereby preventing the grid from falling and improving the overall reliability of use.

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0022] Example 1

[0023] Please see Figure 1 and 2 As shown, the present invention is a handling tool for battery grids, including a mounting plate 1, two symmetrically arranged support rods 2 connected to the mounting plate 1, and a handle rod 101 welded to the mounting plate 1.

[0024] The support rod 2 has a hollow tubular structure. The side wall of the support rod 2 has a straight groove 201 in the axial direction and a storage groove 202 in the circumferential direction. The storage groove 202 is located at the end of the support rod 2 away from the mounting plate 1, and the storage groove 202 is connected to the end of the straight groove 201, so that the storage groove 202 and the straight groove 201 form an L-shaped structure.

[0025] As shown in Figures 5 and 6, a lead screw 3 is rotatably connected inside the support rod 2. The lead screw 3 is fitted with a nut 301, and a clamping block 302 is fixedly connected to the outer wall of the nut 301. One end of the lead screw 3 extends out of the support rod 2 and is fixedly connected to a driven gear 303.

[0026] Specifically, one end of the support rod 2 is a closed structure, and the other end is welded with an installation block 203. One end of the screw rod 3 is rotatably connected to the end wall of the support rod 2, and the other end is rotatably connected to the installation block 203 and passes through the installation block 203.

[0027] Mounting block 203 is slidably connected to mounting plate 1 via a guide rail slider assembly. Mounting plate 1 has a rectangular hole 102, and support rod 2 passes through the rectangular hole 102, so that support rod 2 can move within the range of rectangular hole 102 to adjust the spacing between the two support rods 2, which is convenient to adapt to different sizes of grids.

[0028] Mounting plate 1 is slidably connected to pressing plate 4 via guide rail slider assembly. Pressing plate 4 has a vertically opened strip groove. Mounting plate 1 fixes a limiting rod, which passes through the strip groove, so that the limiting rod can limit the up and down movement position of pressing plate 4.

[0029] like Figure 4 As shown, an arc-shaped pressure plate 406 is welded to the pressing plate 4, and the arc-shaped pressure plate 406 is located above the handle lever 101. Simultaneously, two racks 401 are fixedly connected to the pressing plate 4, and the two racks 401 mesh with two driven gears 303 respectively. A flat shaft 402 is welded to the upper end of each rack 401, or the rack 401 is a cylindrical rack, with the flat shaft 402 and the cylindrical rack forming an integral structure. The flat shaft 402 has external threads. The pressing plate 4 has a strip-shaped slot 403 that fits clearanceably with the flat shaft 402. The flat shaft 402 passes through the strip-shaped slot 403 and is fixed by a nut, thus allowing the position of the rack 401 to be adjusted according to the position of the support rod 2, maintaining meshing between the rack 401 and the driven gears 303.

[0030] Preferably, the mounting block 203 is fixedly connected to two ear plates 204, which are arranged vertically. The rack 401 is movably interlocked with the ear plates 204, thereby limiting the distance between the rack 401 and the driven gear 303 through the ear plates 204, and ensuring the meshing accuracy between the rack 401 and the driven gear 303.

[0031] like Figure 3 and 5 As shown, preferably, the support rod 2 is a flat tube structure. The flat tube structure makes it easier to support the grid. The grid is supported by two support rods 2. At this time, the clamping block 302 is located at the storage slot 202.

[0032] like Figure 8 As shown, the arc-shaped pressure plate 406 presses the pressing plate 4, and the pressing plate 4 drives the two racks 401 to move down. The racks 401 drive the driven gear 303 to rotate, which in turn drives the lead screw 3 to rotate. Since the clamping block 302 is located in the storage slot 202 and cannot move, the lead screw 3 drives the lead screw nut 301 to rotate synchronously.

[0033] like Figure 9 and 10 As shown, when the lead screw 3 drives the lead screw nut 301 to rotate synchronously, causing the clamping block 302 to rotate to the position of the straight groove 201, the pressing plate 4 is pressed down. As the lead screw 3 continues to rotate, the clamping block 302 cannot continue to rotate due to the limitation of the inner wall of the straight groove 201. Therefore, the lead screw 3 drives the lead screw nut 301 to move axially, causing the clamping block 302 to move towards the mounting plate 1, thereby pulling the grid towards the mounting plate 1. When the grid is tightly attached to the mounting plate 1 and cannot move further, the clamping block 302 and the mounting plate 1 are used to clamp the transported grid, thereby avoiding the grid from shaking and falling off during the transport process, effectively improving the overall reliability of use.

[0034] Meanwhile, the rack 401 is fitted with a compression spring 404, which is located between the pressing plate 4 and the ear plate 204. When the plate needs to be removed, the pressing plate 4 is released, and the pressing plate 4 is pushed upward by the compression spring 404 to move and reset, so that the rack 401 drives the driven gear 303 to rotate in the opposite direction, so that the lead screw 3 rotates in the opposite direction, so that the clamping block 302 moves away from the mounting plate 1 and contacts the clamping of the plate.

[0035] Furthermore, when the clamping block 302 moves to the position of the storage slot 202, it cannot move, thereby causing the lead screw 3 to drive the lead screw nut 301 to rotate, causing the clamping block 302 to rotate and be retracted into the storage slot 202, thus facilitating the removal of the grid and preparing for the next transport of the grid.

[0036] Example 2

[0037] like Figure 2 , 3 4 and 7, the mounting plate 1 has two guide rods 501 that are movably inserted. A clamping plate 5 is fixedly connected to one end of the two guide rods 501 near the clamping block 302. The guide rods 501 are fitted with springs 502 located between the clamping plate 5 and the mounting plate 1. When the clamping block 302 moves to pull the grid, the clamping plate 5 cooperates with the clamping block 302 to clamp the transported grid. The springs 502 buffer the clamping force to avoid damage to the grid.

[0038] In a preferred embodiment, the mounting plate 1 is rotatably connected to a screw nut 6 via a bearing. The screw nut 6 is fitted with a screw 601, and a gear 602 is fixedly connected to the outer wall of the screw nut 6. One end of the screw 601 is fixedly connected to a push plate 603 by welding or screws. The push plate 603 has through holes that mate with the guide rods 501 one by one, so that the push plate 603 can only move along the axial direction of the guide rods 501, and the spring 502 is located between the clamping plate 5 and the push plate 603.

[0039] The pressing plate 4 is fixedly connected to a rack 405 that meshes with the gear 602. By pressing the pressing plate 4, the rack 405 drives the screw nut 6 to rotate, thereby driving the screw 601 to move axially. The push plate 603 pushes the spring 502, and the spring 502 pushes the clamping plate 5 to move synchronously, so that the clamping plate 5 and the clamping block 302 move in opposite directions, thereby clamping the grid.

[0040] like Figure 8 and 9 As shown, by moving the clamping plate 5 and the clamping block 302 toward each other, the distance between the clamping plate 5 and the clamping block 302 can be reduced to the maximum extent when the downward stroke of the pressing plate 4 is constant. This allows the plate to be clamped even when handling a small number of plates, thus improving the overall adaptability and practicality.

[0041] The number of clamping plates or the clamping force are controlled by the downward movement of the pressing plate 4; that is, the fewer the plates, the greater the downward movement of the pressing plate 4. Furthermore, both the clamping plate 5 and the push plate 603 are made of nylon. Using nylon not only reduces the overall weight and processing difficulty but also avoids scratches on the plate surface, thus improving ease of use and reliability.
