Description

Technical Field

[0001] The invention relates to the technical field of battery stack mechanical automation, in particular to a carbon felt flexible grasping manipulator. Background Art

[0002] Liquid flow batteries have the advantages of good current conversion capability, flexible structural design, good safety, and easy operation. They are a new type of green secondary battery suitable for large-scale energy storage. Carbon felt is an anisotropic three-dimensional structure, which is conducive to the flow and mass transfer of electrolytes. It also has the advantages of low price, good conductivity, and large surface area. It is the most widely used electrode material in commercial liquid flow batteries.

[0003] With the miniaturization of battery stacks, carbon felt, as an important component of the battery stack system, plays a decisive role in the conductivity of the battery stack. In the battery stack system, carbon felt is usually assembled in the groove of the liquid flow plate, so interference fit is often used during assembly to ensure the close contact and stability between the carbon felt and the surface of the liquid flow plate groove to prevent electrolyte leakage from causing battery performance degradation and other problems.

[0004] At present, this assembly process is usually done manually, which is not only time-consuming and laborious, but also has fine fibers on its surface due to the structural characteristics of carbon felt, which can easily affect the health of workers. At the same time, due to the anisotropic three-dimensional structure of carbon felt, it is soft and breathable, and it is not easy to be sucked up by a vacuum suction cup. Summary of the invention

[0005] The technical problem to be solved by the present invention is to address the deficiencies of the above-mentioned prior art and to provide a carbon felt flexible grasping robot, which can locate the grasped carbon felt. After the position is determined, the carbon felt guide side pressure assembly is first used to move the carbon felt downward along the guide slope, thereby pressing the carbon felt around into the carbon felt assembly groove of the liquid flow plate; then, the carbon felt transfer positive pressure assembly is pressed downward to flatten the carbon felt, thereby achieving an interference fit between the carbon felt and the carbon felt assembly groove.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0007] A carbon felt flexible grasping manipulator comprises a carbon felt guide side pressure component and a carbon felt transfer positive pressure component.

[0008] Assuming that the length and width of the carbon felt are L and W respectively, and the length and width of the carbon felt assembly groove in the liquid flow plate are L0 and W0 respectively, then L>L0, W>W0.

[0009] The carbon felt guide side pressure assembly comprises a guide plate frame, a side pressure plate and a side pressure driving device.

[0010] The guide plate frame can be coaxially covered on the outer periphery of the carbon felt assembly groove, and the inner wall surfaces around the guide plate frame are all provided with guide inclined surfaces which gradually shrink from top to bottom; the guide plate frame includes an expansion opening at the top and a contraction opening at the bottom.

[0011] Assuming that the length and width of the expanded opening are L1 and W1 respectively, and the length and width of the contracted opening are L2 and W2 respectively, then L1≥L, W1≥W, L2≤L0, W2≤W0.

[0012] A side pressure plate is arranged on the top of each of the four guide inclined surfaces of the guide plate frame, and each side pressure plate is provided with at least one side pressure driving device. Each side pressure plate can slide along the guide inclined surface under the drive of the corresponding side pressure driving device.

[0013] The carbon felt transfer positive pressure component is coaxially embedded in the guide plate frame and connected with the guide plate frame.

[0014] The carbon felt transfer positive pressure assembly comprises a positive pressure plate, a positive pressure drive assembly and a carbon felt grabbing assembly.

[0015] Assuming that the length and width of the positive pressure plate are L3 and W3 respectively, then L3<L2, W3<W2.

[0016] The positive pressure plate clamping assembly can drive the positive pressure plate to rise and fall in height.

[0017] The carbon felt grabbing assembly is arranged on the positive pressure plate and can be used for layered positioning and grabbing of the carbon felt.

[0018] Each side pressure plate is provided with at least two side pressure driving devices; wherein the two side pressure driving devices are symmetrically arranged at two ends of the corresponding side pressure plate.

[0019] The carbon felt grabbing assembly is a plurality of pneumatic pins arranged on the positive pressure plate, and each pneumatic pin includes a needle seat and a needle rod; wherein, the needle seat is arranged on the top of the positive pressure plate, and the needle rod head can pass through the bottom surface of the positive pressure plate, and the passing length does not exceed the thickness of a layer of carbon felt.

[0020] The length of the needle bar head protruding from the bottom surface of the positive pressure plate is one half to two thirds of the thickness of the carbon felt.

[0021] The pneumatic pins are evenly arranged along the two long sides of the positive pressure plate.

[0022] The positive pressure driving assembly includes a clamping mounting plate, a lifting plate and a lifting driving device.

[0023] The lifting plate is coaxially installed just above the positive pressure plate and placed on the top of the needle seat of the pneumatic pin. The lifting plate can drive the positive pressure plate to rise and fall synchronously.

[0024] The clamping installation plate is coaxially arranged just above the lifting plate and is connected to the guide plate frame through a connecting column.

[0025] The lifting drive device is arranged on the clamping mounting plate and is used for driving the lifting plate to move up and down in height.

[0026] The positive pressure driving component also includes a lifting guide column, which passes through the clamping mounting plate and the lifting plate in sequence; the top and bottom ends of the lifting guide column are both provided with lifting limit components.

[0027] It also includes a carbon felt detection component, which can be used to detect whether carbon felt is grabbed by the carbon felt grabbing component.

[0028] A method for assembling carbon felt by using a carbon felt flexible grasping manipulator comprises the following steps.

[0029] Step 1: Grab the carbon felt, which specifically includes the following steps:

[0030] Step 1-1, one-time transfer of the carbon felt flexible grasping manipulator: a robot equipped with the carbon felt flexible grasping manipulator moves the carbon felt flexible grasping manipulator to just above the carbon felt grasping station.

[0031] Step 1-2, carbon felt bonding: the carbon felt transfer positive pressure assembly in the carbon felt flexible grasping manipulator is lowered in height, and the bottom surface of the positive pressure plate is bonded with the top surface of the carbon felt at the top of the carbon felt grasping station.

[0032] Step 1-3, carbon felt grabbing: the pneumatic pin passes through the bottom surface of the positive pressure plate and is inserted into the top layer of carbon felt; by controlling the length of the pneumatic pin passing through the bottom surface of the positive pressure plate so that it does not exceed the thickness of a layer of carbon felt, a single layer of carbon felt can be grabbed.

[0033] Step 2, carbon felt detection: the carbon felt flexible grasping manipulator rises in height, and the carbon felt detection component detects whether the pneumatic pin has grasped the carbon felt;

[0034] Step 3, carbon felt positioning: when there is carbon felt on the pneumatic pin, the carbon felt transfer positive pressure assembly carries the grabbed carbon felt and rises in height synchronously until the positive pressure plate passes through the guide plate frame in the carbon felt guide side pressure assembly from bottom to top; at this time, the carbon felt will pass through the shrinkage of the four guide bevels on the inner side of the guide plate frame, and be located at the flared position of the four guide bevels, and the top surface is in contact with the top surfaces of the four side pressure plates, thereby realizing the positioning of the carbon felt; then, the pneumatic pin is reset to release the plug-in contact with the carbon felt.

[0035] Step 4, secondary transfer by the carbon felt flexible grasping manipulator: the carbon felt flexible grasping manipulator transfers the positioned carbon felt to just above the carbon felt assembly station, and sets the guide plate frame coaxial cover in the carbon felt guide side pressure assembly on the outer periphery of the carbon felt assembly groove.

[0036] Step 5, side pressure on the edge of the carbon felt: the four side pressure plates in the carbon felt guide side pressure assembly slide downward along the corresponding guide slopes in batches or synchronously, and move the carbon felt down along the four guide slopes to the shrinkage; as the four side pressure plates continue to move downward, the carbon felt is sealed and side-pressed around the carbon felt assembly groove of the liquid flow plate below; then, the four side pressure plates are reset.

[0037] Step 6, positive pressure on carbon felt: driven by the positive pressure plate assembly, the positive pressure plate is lowered in height and positively presses the carbon felt located directly below to the carbon felt assembly groove, thereby achieving an interference fit between the carbon felt and the carbon felt assembly groove.

[0038] In step 5, the four side pressure plates include two long-side side pressure plates or two short-side side pressure plates; wherein, the two long-side side pressure plates or the two short-side side pressure plates first perform synchronous side pressure on two opposite sides of the carbon felt, and then the remaining two side pressure plates are used to perform synchronous side pressure on the other two opposite sides.

[0039] The present invention has the following beneficial effects:

[0040] 1. The present invention can automatically assemble the interference-fit carbon felt and liquid flow plate, solves the assembly and positioning problem of the carbon felt, which is a key component of the battery stack, realizes the automation of the grasping and assembly of the carbon felt, and also solves the problems of the difficulty, time-consuming and low efficiency of manual assembly, thereby improving the assembly efficiency.

[0041] 2. The present invention can locate the gripped carbon felt. After the position is determined, the carbon felt guide side pressure assembly is first used to move the carbon felt downward along the guide slope, thereby pressing the carbon felt around into the carbon felt assembly groove of the liquid flow plate; then, the carbon felt transfer positive pressure assembly is pressed downward to flatten the carbon felt, thereby achieving an interference fit between the carbon felt and the carbon felt assembly groove.

[0068] A side pressure plate is arranged on the top of each of the four guide inclined surfaces of the guide plate frame, and each side pressure plate is provided with at least one side pressure driving device. Each side pressure plate can slide along the guide inclined surface under the drive of the corresponding side pressure driving device.

[0069] In this embodiment, each side pressure plate is provided with two side pressure driving devices, which are symmetrically arranged at the two ends of the corresponding side pressure plate. Each side pressure driving device is preferably a side pressure cylinder 33, which is mounted on an inclined side pressure support plate 331, and the side pressure support plate is mounted on a triangular support 332, which can be connected to the outer edge of the guide plate frame.

[0070] The carbon felt transfer positive pressure component is coaxially embedded in the guide plate frame and connected with the guide plate frame.

[0071] The carbon felt transfer positive pressure assembly comprises a positive pressure plate 43, a positive pressure drive assembly and a carbon felt grabbing assembly.

[0072] Assuming that the length and width of the positive pressure plate are L3 and W3 respectively, then L3<L2, W3<W2, that is, the positive pressure plate can freely pass through the shrinkage of the guide slope.

[0073] The carbon felt grabbing assembly is arranged on the positive pressure plate and can be used for layered positioning and grabbing of the carbon felt.

[0074] The carbon felt grabbing assembly is preferably a plurality of pneumatic pins 44 arranged on the two long sides of the positive pressure plate, each pneumatic pin comprising a needle seat and a needle rod; wherein the needle seat is arranged on the top of the positive pressure plate, the needle rod head can pass through the bottom surface of the positive pressure plate, and the passing length does not exceed the thickness of a layer of carbon felt, and is further preferably one half to two thirds of the thickness of the carbon felt.

The lifting plate can drive the positive pressure plate to rise and fall synchronously.

[0078] The clamping mounting plate is coaxially arranged just above the lifting plate and is connected to the guide plate frame via a plurality of connecting columns 411 .

In this embodiment, the carbon felt detection assembly is preferably a laser sensor mounted on the clamping mounting plate through a sensor bracket 51, and laser perforations 52 are provided on the lifting plate and the positive pressure plate for the laser detection line to pass through.

[0082] Furthermore, the detection method of the laser displacement sensor is specifically as follows: the laser displacement sensor is installed in a fixed position, and before the assembly begins, the laser displacement sensor records the distance when the carbon felt is inserted by the pneumatic pin under normal conditions. During the assembly process, the sensor continuously emits a laser beam and receives reflected light to measure the distance between the carbon felt and the sensor in real time. If the carbon felt has not fallen, the distance measured by the sensor should be consistent with the initially recorded reference value or within the allowable tolerance range. If the carbon felt falls or moves beyond the predetermined range, the laser displacement sensor will detect a significant distance change or position offset. The control system built into the sensor can recognize this change and trigger an alarm or transmit information to the control system.
