Description

Grid leveling device

technical field

The invention relates to the technical field of grid weaving manufacturing, in particular to a grid leveling device.

Background technique

The grid is an important component of the lead-acid battery, which is used to coat the active material and realize the charging and discharging function of the battery. The current grid includes two types of expanded mesh and casted mesh. The expanded mesh is generally woven by a weaving machine. During the process of weaving the grid by the weaving machine, it is necessary to continuously collect the formed grid. Since the production factory will increase the width of the weaving machine in order to improve the manufacturing efficiency of the grid, the grid generally has a large width, which is inconvenient to collect and transport.

In order to eliminate the restriction on the width of the grid and improve work efficiency, a grid winding device is now used, which can simultaneously wind up multiple grids. In the specific winding process, both sides of the grid need to be tightened, and then the grid is divided into two longitudinally from the middle of the grid by a cutting knife. However, in the process of cutting the grid, the force between the cutting knife and the grid will cause the edge of the grid to appear irregular, which will easily cause damage to the operator when the operator handles the collected grid roll.

Contents of the invention

The present invention intends to provide a grid leveling device to solve the problem that the cut edge of the grid is not neat after the existing cutting knife cuts the grid, so as to avoid injury to operators during operation.

In order to achieve the above object, the technical solution of the present invention is: a grid leveling device, including a frame body, a first screw for fixing the cutting knife, a driving mechanism for driving the first screw, and the driving mechanism drives the first screw Drive the blade of the cutting knife to align with the grid;

At least two fixing mechanisms are arranged on the outer frame body of the first screw rod, and the lower parts of the fixing mechanisms are slidingly connected with a pressing mechanism;

The pressing mechanism includes a U-shaped frame with an opening facing upwards and a connecting plate threadedly connected with the first screw rod, the connecting plate is fixed on the upper part of the U-shaped frame, and the side wall of the U-shaped frame is provided with an air chamber that forms an air pump structure with the fixing mechanism , the air cavity communicates with a trachea facing below the U-shaped frame; the cutting knife runs through the lower part of the U-shaped frame, and the bottom of the U-shaped frame is also provided with a button switch electrically connected to the driving mechanism.

The principle and beneficial effects of this scheme are: the driving mechanism will drive the first screw to rotate, and the first screw will drive the connecting plate to slide vertically downward under the thread cooperation, so that the connecting plate slides downward with the U-shaped frame, and the U-shaped frame The bottom of the bottom will be against the grid, and now the button switch will shrink under the extrusion of the grid, thereby closing the driving mechanism, and the driving mechanism will stop rotating, thus pressing the upper surface of the grid. During the transmission process, the grid passes through the cutting knife and is thus cut into two pieces. Due to the mutual force between the cutting knife and the grid, the cut part of the grid will be lifted, but at this time the U-shaped frame presses the cut part. Part, so that the cut part of the grid will not lift up, so that the grid can be cut flat. Compared with the traditional cutting method, the U-shaped frame is used to press the cut part of the grid to avoid uneven cutting of the grid.

As the U-shaped frame slides down, the air chamber draws air through the trachea. After the grid is conveyed away, the button switch is no longer squeezed by the grid, so that the circuit of the driving mechanism is turned on, the driving mechanism is started to drive the first screw to reverse, the U-shaped frame slides upward, and the gas in the air cavity passes through the trachea Exhaust, the exhaust gas cleans the dust and cutting waste on the grid. Compared with the traditional cutting method, a certain amount of waste will be generated during the grid cutting process, which will affect the quality of the grid. Clean up the waste during the cutting process to avoid manual cleaning, thereby improving work efficiency.

Further, the driving mechanism is a servo motor or a stepping motor. The servo motor and the stepping motor rotate according to a certain angle, so that the torque of the servo motor and the stepping motor is constant, and the distance driven by the first screw to drive the U-shaped frame to slide is constant, and at the same time, the blade of the cutting knife can be aligned with the grid .

Further, the fixing mechanism includes a fixing rod and a sliding rod fixed on the fixing rod, and the sliding rod extends into the air cavity and is slidably connected with the U-shaped frame. The fixed rod can extend the formation of the U-shaped frame. The sliding rod is in the air cavity. The sliding rod, the air cavity and the air pipe form a mechanism similar to an air pump, so that the air cavity can suck and discharge gas, and the gas can be used to control the air on the grid. Clean up dust or debris.

Further, the lower part of the cutting knife is fixed with a second screw rod whose thread direction is opposite to that of the first screw rod. The second screw rod is provided with a pressing mechanism outside. The pressing mechanism includes a pressing frame and a fixing plate, and the fixing plate is fixed on the pressing frame. and the fixing plate is threadedly connected with the second screw rod, the side wall of the compression frame is provided with an air cavity, the air cavity is connected with an air duct facing the upper part of the compression frame, and the support rod fixed on the frame body is slidably connected in the air cavity . When the first screw rotates, the first screw will drive the cutting knife to rotate, and the cutting knife will drive the second screw to rotate, and the second screw will drive the compression frame to slide upward through the fixed plate, so that the compression frame presses the lower part of the grid. When the air cavity is under the action of the support rod, the air cavity sucks gas through the air pipe, and waste debris such as dust can be sucked into the air cavity. In this way, not only the dust removal effect of the grid is enhanced, but also the upper surface and the lower surface of the grid can be pressed simultaneously to improve the pressing effect.

Further, sandpaper layers are provided on the upper part of the pressing frame and the lower part of the U-shaped frame. During the grid transfer process, the existing burrs on the grid can be removed by sanding. At the same time, the gas blown out from the air cavity and the wind cavity can clean the burrs under grinding.

Further, the bottom of the U-shaped frame is provided with a groove, the button switch is located in the groove, and the bottom of the button switch is provided with a spring against the groove. When the button switch is squeezed, it will slide towards the groove. When it cannot slide under the action of the spring, the button switch will be closed, so that the circuit of the driving mechanism will be disconnected, and the driving mechanism will stop working, so that the pressing mechanism can Clamp the grid completely to achieve the purpose of pressing the grid.

Further, the bottom of the button switch is provided with a sponge layer. The sponge layer is used to protect the push button switch and avoid damage caused by friction between the push button switch and the grid.
