Coated Blade Battery Size Measuring and Insulation Resistance Measuring Machine

Abstract

The present invention provides a size measurement and insulation resistance measurement machine for encapsulated blade batteries, which includes a machine table and a loading and handling device, a transfer device, an equidistant transfer device, a constant-pressure size measurement device, a constant-pressure insulation resistance measurement device, a flipping device, and a discharging and handling device arranged thereon. The constant-pressure size measurement device is used to press the surface to be measured of the battery, and measures the length, width, and thickness of the battery through its displacement sensor. The constant-pressure insulation resistance measurement device presses the surface to be measured of the battery through its conductive rubber plate and measures the insulation resistance value of the surface to be measured. When measuring the size of the blade battery, an appropriate pressure can be applied to the battery surface, which can eliminate deformation problems such as bulging and depression on the battery surface, and overcome the problem that the existing measurement equipment has inaccurate measurement due to the deformation of the battery itself. The constant-pressure insulation resistance measurement device uses a conductive rubber plate as a probe and measures while sticking to each surface to be measured of the battery under appropriate pressure, avoiding the problem of damaging the insulation film when using a conventional probe to contact the insulation film.

Description

Technical Field

[0001] The present invention belongs to the technical field of battery manufacturing and testing equipment, and particularly relates to a machine for measuring the size and insulation resistance of a film-coated blade battery. Background Art

[0002] When single primary cells are combined into a module, they will be closely adjacent to each other. In order to achieve electrical isolation, it is necessary to wrap an insulating film on the surfaces of the single primary cells that may be in close contact. In order to eliminate the film-coated single primary cells with an insulation resistance value less than a predetermined standard value caused by piercing, cracking, damage, etc. of the insulating film, it is necessary to measure the insulation resistance of the film-coated single primary cells.

[0003] Since the insulating film cannot be touched with a probe or a probe block to prevent piercing the insulating film, and all possible adjacent insulating film surfaces on the outer surface of the film-coated single primary cell must be measured, a conductive rubber plate is technically used as a probe and is attached to each insulating film surface to be measured of the film-coated single primary cell under appropriate pressure for measurement.

[0004] A kind of blade single primary cell (hereinafter referred to as blade battery), see Figure 1 、 Figure 2 , the outer surface includes a first end face 11, a second end face 12, a first side face 13, a second side face 14, a first large face 15, a second large face 16, a top face 17 of the first pole (negative pole), a top face 18 of the second pole (positive pole) and a two-dimensional code 19. Among them, the top face 18 of the second pole (positive pole) is located on the second end face 12, the top face 18 of the second pole (positive pole) is electrically connected to the second end face 12 and is electrically connected to the outer surface of the entire housing of the blade battery except the top face 17 of the first pole (negative pole). Except for the exposed top face 17 of the first pole (negative pole), the top face 18 of the second pole (positive pole) and the two-dimensional code 19, the remaining outer surface of the entire housing of the blade battery is coated with an insulating film.

[0005] When detecting the insulation resistance of the insulation film of the encapsulated blade battery 10, select the top surface 18 of the second pole (positive pole) as the first pole for detecting the insulation resistance, representing the outer surface of the housing of the entire blade battery except the top surface 17 of the first pole (negative pole). Use the four adjacent surfaces of the first side 13, the second side 14, the first large surface 15, and the second large surface 16 of the encapsulated blade battery 10 when assembled into a module in parallel as the second pole for detecting the insulation resistance. Connect the two poles of the resistance meter to the first pole and the second pole to measure the minimum resistance value between the outer surface of the housing of the entire blade battery and the four encapsulated surfaces of the first side 13, the second side 14, the first large surface 15, and the second large surface 16 of the encapsulated blade battery 10. Then compare the measured minimum resistance value with the predetermined standard value. When the minimum resistance value is greater than or equal to the predetermined standard value, it is determined that the insulation resistance value of the insulation film encapsulated by the encapsulated blade battery 10 is qualified; when the minimum resistance value is less than the predetermined standard value, it is determined that the insulation resistance value of the insulation film encapsulated by the encapsulated blade battery 10 is unqualified.

[0006] The pressing pressure applied during the measurement of the insulation resistance of the encapsulated blade battery 10 generally requires: adjustable in the thickness direction (50 - 800) ± 10 kgf; in the width direction (10 ± 1) kgf, and in the length direction (2 ± 1) kgf, which can be adjusted according to the specific specifications and test requirements of the encapsulated blade battery 10.

[0007] The overall dimensions of the encapsulated blade batteries 10 after being closely arranged together when assembled into a module need to meet the maximum dimension requirements of the accommodation space of the module housing. Therefore, the requirements for the dimensional error of the outer shape of a single encapsulated blade battery 10 are relatively strict, and it is necessary to precisely measure the length, width, thickness, and pole height of the outer shape of the encapsulated blade battery 10. See Figure 1 、 Figure 2 , the distance between the first end face 11 and the second end face 12 is the battery length, the distance between the first side 13 and the second side 14 is the battery width, the distance between the first large surface 15 and the second large surface 16 is the battery thickness, the distance between the top surface 17 of the first pole and the first end face 11 is the height of the first pole of the battery, and the distance between the top surface 18 of the second pole and the second end face 12 is the height of the second pole of the battery.

[0008] Traditional measuring equipment measures by using a contact measuring tool to touch the surface of the battery or by using a non-contact light wave rangefinder or acoustic rangefinder to irradiate the surface of the battery. Measuring by using a contact measuring tool to touch the surface of the battery and measuring by using a non-contact light wave rangefinder or acoustic rangefinder to irradiate the surface of the battery both have problems of inaccurate measurement due to the instability of the battery itself.

[0009] For the encapsulated blade battery 10, there may be problems such as insufficient rigidity of the outer shell, surface bulging, depression or deformation. Such surface bulging, depression or deformation of the encapsulated blade battery 10 can be eliminated by applying appropriate force during the assembly of the battery module. Therefore, it is allowed to measure the outer dimensions of the encapsulated blade battery 10 under the state of being constrained by appropriate force application.

[0010] When measuring the dimensions of the encapsulated blade battery 10, the pressing pressure applied is generally required to be: adjustable from (100 - 800) ± 10 kgf for thickness measurement; (10 ± 1) kgf for width measurement, and (2 ± 1) kgf for length measurement, which can be adjusted according to the specific specifications and test requirements of the battery. Summary of the Invention

[0011] The purpose of the present invention is to provide a measuring machine for the dimensions and insulation resistance of an encapsulated blade battery, which can solve the problem of inaccurate measurement due to the deformation of the battery itself in the existing battery outer dimension measurement technology; and, it can also measure the insulation resistance of the encapsulated battery without damaging the insulation film, so as to eliminate the encapsulated batteries with insulation resistance values lower than the predetermined value caused by puncture, cracking, damage, etc. of the insulation film.

[0012] The present invention is implemented as follows. A measuring machine for the dimensions and insulation resistance of an encapsulated blade battery includes a machine table and a feeding and handling device, a transfer device, an equidistant transfer device, a constant-pressure dimension measurement device, a constant-pressure insulation resistance measurement device, a flipping device, and a discharging and handling device arranged thereon;

[0013] The constant-pressure dimension measurement device includes:

[0014] A dimension measurement transfer mechanism, including a dimension measurement transfer support, a dimension measurement transfer driving member, and a dimension measurement transfer slide plate. The dimension measurement transfer support is fixed on the tabletop of the machine table, the dimension measurement transfer driving member is fixed on the dimension measurement transfer support, the dimension measurement transfer slide plate is fixed on the movable end of the dimension measurement transfer driving member. There are two sets of four dimension measurement carrier frame slide rods located at the four vertices of a rectangle and two dimension measurement carrier frame support members on the dimension measurement transfer slide plate. The dimension measurement carrier frame support members are located at the center of each set of four measurement carrier frame slide rods. The two sets of measurement carrier frame slide rods and the two dimension measurement carrier frame support members are fixedly combined in pairs at both ends of the dimension measurement transfer slide plate. The dimension measurement transfer driving member can drive the dimension measurement transfer slide plate to move with the two sets of dimension measurement carrier frame slide rods and the two dimension measurement carrier frame support members;

[0015] Two sets of carrier frames are respectively seated on the two dimension measurement carrier frame support members of the dimension measurement transfer slide plate;

[0016] Two sets of constant-pressure length and width measuring mechanisms, which are respectively fixed on the two sets of the carriers;

[0017] Two sets of constant-pressure thickness measuring mechanisms, which are respectively fixed on the tabletop of the machine platform and are respectively arranged at both ends of the size measuring transfer mechanism;

[0018] The size measuring transfer mechanism can drive the two sets of carriers to drive the two sets of constant-pressure length and width measuring mechanisms to alternately enter and exit the two sets of constant-pressure thickness measuring mechanisms. When one set of constant-pressure length and width measuring mechanisms is outside the two sets of constant-pressure thickness measuring mechanisms, loading or unloading can be carried out. When the other set of constant-pressure length and width measuring mechanisms enters one set of constant-pressure thickness measuring mechanisms, constant-pressure length and width measurement can be carried out simultaneously, and cooperate with this set of constant-pressure thickness measuring mechanisms to carry out constant-pressure thickness measurement;

[0019] Loading or unloading is carried out simultaneously with constant-pressure length and width measurement and constant-pressure thickness measurement, forming an assembly line for loading and unloading and size measurement;

[0020] The constant-pressure insulation resistance measuring device includes:

[0021] A resistance measuring transfer mechanism, including a resistance measuring transfer support, a resistance measuring transfer driving part and a resistance measuring transfer slide plate. The resistance measuring transfer support is fixed on the tabletop of the machine platform, the resistance measuring transfer driving part is fixed on the resistance measuring transfer support, the resistance measuring transfer slide plate is fixed on the movable end of the resistance measuring transfer driving part, and the resistance measuring transfer driving part can drive the resistance measuring transfer slide plate to move;

[0022] Two carriers, which are respectively fixed at both ends of the resistance measuring transfer slide plate;

[0023] Two sets of end surface pressing measurement mechanisms, which are respectively fixed at both ends of the two carriers and are matched with the two carriers;

[0024] Two sets of side surface pressing measurement mechanisms, which are respectively fixed at both ends of the resistance measuring transfer support;

[0025] Two sets of large surface pressing measurement mechanisms, which are respectively fixed at both ends of the resistance measuring transfer support, straddle outside the two sets of side surface pressing measurement mechanisms, and are matched with the two sets of side surface pressing measurement mechanisms;

[0026] The resistance measurement transfer mechanism can drive the two carriers and the two sets of the end surface pressure measurement mechanisms to alternately enter and exit the two sets of the large surface pressure measurement mechanisms. When one carrier and its matching set of the end surface pressure measurement mechanisms are outside the two sets of the large surface pressure measurement mechanisms, they can load or unload materials. When another carrier and its matching set of the end surface pressure measurement mechanisms enter a set of the large surface pressure measurement mechanisms, they can simultaneously measure the insulation resistance of the insulating film covered by the first large surface, the second large surface, the first side surface and the second side surface of the coated blade battery in cooperation with a set of the side pressure measurement mechanisms in the set of the large surface pressure measurement mechanisms.

[0027] Loading or unloading of materials and insulation resistance measurement in cooperation with the end face pressure measuring mechanism, the side face pressure measuring mechanism and the large face pressure measuring mechanism are performed simultaneously, forming an assembly line for loading and unloading of materials and insulation resistance measurement.
