[0002] At present, in the lithium battery diaphragm production workshop, large roll diaphragm is cut into various specifications of 3-inch and 6-inch diaphragm products with multiple and diverse width specifications. The width sizes of many small diaphragm roll products are difficult to distinguish by the naked eye. It is easy for the diversity of products to cause mixing in the packaging and shipping area, and the wrong products are sent out, which brings troubles to production and management.

[0003] Generally, before testing the membrane coil products, the products need to be calibrated. The so-called calibration requires a standard product to calculate the reference total width, and then compare it with the reference total width to get a difference. If the absolute value of this difference is greater than the absolute value of the product width tolerance, the product exceeds the tolerance and the system will mark this product as a defective product. Similarly, if the absolute value of this difference is less than the absolute value of the product width tolerance, this product will be marked as a good product. However, the existing width detection devices are difficult to apply to lithium battery membrane coils. Summary of the invention

[0007] In one embodiment, the left side fixing device includes a left triangular suspension fixing member 207 and a suspension support frame 204. The left triangular suspension fixing member 207 is used to be fixed above the detection mechanism. The upper part of the suspension support frame 204 is fixedly connected to the left triangular suspension fixing member 207. The left side Z-axis slide 103 is movably connected to the suspension support frame 204.

[0008] In a preferred embodiment, the left high-precision sensor 107 is fixedly connected to the left Z-axis slide 103 via the left sensor bending member 208 .

[0009] In one solution, a profile 74 and a triangular support 78 are provided below the screw module 81 for fixing.

[0010] In one solution, a movable plate 77 that can move with the screw module 81 is provided above the screw module 81 , and a 3-inch limit plate 90 and a 6-inch limit plate 80 are provided on the movable plate 77 .

DETAILED DESCRIPTION

[0021] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but the protection scope of the present invention is not limited to the following examples.

[0022] like Figure 1 As shown, the lithium battery diaphragm coil width measuring detection mechanism of the present invention comprises a left fixing device, a left Z-axis slide 103, a left high-precision sensor 107, a screw module 81, a right Z-axis slide 96, an in-position distance sensor 76 and a right high-precision sensor 89. The "left side" in the left Z-axis slide 103 and the left high-precision sensor 107 in the present device and the "right side" in the right Z-axis slide 96 and the right high-precision sensor 89 are relative concepts, which can indicate that the two components are on the same side, but they do not mean that these components can only be on the left or right side, because the left and right sides viewed from one angle are the opposite right and left sides viewed from another angle.

[0023] The left Z-axis slide 103 in the device is arranged on the left fixing device, wherein the left fixing device can be a fixed position device, which can be fixed above the width measuring detection mechanism or fixed on the ground. In order to facilitate operation and not affect the operation of other components, the left fixing device is preferably fixed above. Figure 1For example, the left fixing device includes a left triangular suspension fixing member 207 and a suspension support frame 204. The left triangular suspension fixing member 207 is used to be fixed above the detection mechanism. The upper part of the suspension support frame 204 is fixedly connected to the left triangular suspension fixing member 207, and the left Z-axis slide 103 is movably connected to the suspension support frame 204.

[0024] The left Z-axis slide 103 in the device, wherein the Z-axis refers to the direction perpendicular to the ground, can be adjusted up and down in height on the left fixing device or the suspension support frame 204. The left high-precision sensor 107 is fixedly connected to the left Z-axis slide 103, so that the left high-precision sensor 107 is fixed in the horizontal direction, but can be adjusted up and down according to the left Z-axis slide 103 in the vertical direction of the ground. If necessary, the left high-precision sensor 107 can also be fixedly connected to the left Z-axis slide 103 through the left sensor bending piece 208, so that the detection direction of the left high-precision sensor 107 can be adjusted.

[0025] The screw module 81 in the device can move left and right. A profile 74 and a triangular support 78 for fixing are provided below the screw module 81, and the screw module 81 is set on the ground through them.

[0026] The screw module 81 is connected to the lower part of the right Z-axis slide 96 through a connecting piece, and the connecting piece here can be a connecting plate, a connecting block, etc. Figure 1 A movable plate 77 is used for connection, that is, a movable plate 77 that can move with the screw module 81 is provided above the screw module 81, and a 3-inch limit plate 90 and a 6-inch limit plate 80 are provided on the movable plate 77. The 3-inch limit plate 90 and the 6-inch limit plate 80 can be quickly positioned when adjusting the height of different types of lithium battery diaphragm coil products.

[0027] The device can be provided with a position distance sensor 76 and a right high-precision sensor 89 directly or through a connecting piece on the upper part of the right Z-axis slide 96. Figure 1 In the scheme, the lower part of the right Z-axis slide 96 is connected to the slide lower vertical plate 93, the upper part of the right Z-axis slide 96 is connected to the slide upper vertical plate 98, and the slide lower vertical plate 93 is fixedly connected to the moving plate 77 through a pad 94 and a strip plate. The in-position distance sensor 76 and the right high-precision sensor 89 are respectively arranged on a horizontal plate 97, and the horizontal plate 97 is fixedly connected to the slide upper vertical plate 98.

[0028] In a specific solution, one end of the horizontal plate 97 is fixedly connected to the vertical plate 98 on the slide, and the other end of the horizontal plate 97 is connected to the upper end of a shaft 101 through a linear ball bushing 99, and the lower end of the shaft 101 is connected to the strip plate or the moving plate 77. This structure can make the in-position distance sensor 76 and the right high-precision sensor 89 more stable and less likely to shake.

[0029] The detection directions of the left high-precision sensor 107 and the right high-precision sensor 89 are opposite, and the detection directions of the in-place distance sensor 76 and the right high-precision sensor 89 are the same. A detection space for placing the lithium battery diaphragm roll product 124 is reserved between the left high-precision sensor 107 and the right high-precision sensor 89, for example Figure 1 The lithium battery diaphragm roll product 124 is moved from the diaphragm product support frame 122 into the inspection space for inspection.

[0030] When in use, the left high-precision sensor 107 does not move, and after the lithium battery diaphragm coil product 124 moved into the detection space is in place, the distance value 1 from the left side of the product to the left high-precision sensor 107 can be measured, and the right high-precision sensor 89 moves with the screw module 81 until the distance sensor 76 has a signal, the screw module 81 stops moving, and the right high-precision sensor 89 measures the distance value 2 from the right side of the product to the right high-precision sensor 89. The result can be obtained by the software according to the algorithm formula "calibrated value-distance value 1-distance value 2=actual width of the product", and then after obtaining the actual width of the product, the software system determines whether the product is good or bad.

[0031] Taking the detection of 6-inch diaphragm products as an example, the lithium battery diaphragm roll product 124 moves to the detection position in the detection space; after the left high-precision sensor 107 receives the signal that the diaphragm product is in place, it starts to detect the spacing on the left and outputs a distance value of 1; at the same time, the screw module 81 starts to move after receiving the signal that the lithium battery diaphragm roll product 124 is in place, and the screw module 81 drives the right high-precision sensor 89 and the in-place distance sensor 76 to move at the same time. After the infrared laser of the in-place distance sensor 76 hits the product, a signal is given to the screw module 81, and the screw module 81 stops moving. The high-precision sensor 89 on the right starts to measure the spacing on the right side of the diaphragm product and outputs a distance value of 2; at this time, the system software will use the formula to determine whether the product is a good product, and mark the corresponding product, and the width detection is completed.

[0032] Taking the inspection of 3-inch diaphragm products as an example, it is necessary to first adjust the left Z-axis slide 103 to drop 38mm, and at the same time adjust the right Z-axis slide 96 to drop 38mm, so that the left high-precision sensor 107 and the right high-precision sensor 89 can be dropped to the appropriate position at the same time. The equipment is adjusted to automatic mode, and after calibrating the 3-inch diaphragm product, the inspection process of the 6-inch product can be repeated, and the inspection of the 3-inch diaphragm product is completed.

[0033] The above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed by the present invention according to the technical solution and inventive concept of the present invention, which should be covered by the protection scope of the present invention.
