[0040] Embodiments

[0041] Reference Figures 1-3 The present embodiment discloses a kind of electrode sheet 1101 blanking detection device, for the separation force between electrode sheet 1101 and material belt 110 before blanking is detected, to ensure the normal progress of subsequent blanking.

[0042] The electrode sheet 1101 blanking detection device of the embodiment comprises a lifting piece 10, a first clamping piece 20, a second clamping piece 30 and a first seat body 40;

[0043] The lifting piece 10 is slidably connected to the vertical plate 60 and can move up and down along the vertical plate 60. The lifting piece 10 is fixedly connected with a punch 101 and a first elastic piece 102. One end of the first elastic piece 102 is connected to the lifting piece 10, and the other end is connected to a force gauge (not shown in the figure) to measure and display the elastic force of the first elastic piece 102.

[0044] The first clamping piece 20 is provided with a first through hole 201 through which the punch 101 passes.

[0045] The second clamping piece 30 is located below the first clamping piece 20. The second clamping piece 30 and the first clamping piece 20 are used to place a material strip 110. The material strip 110 is provided with electrode sheets 1101. The second clamping piece 30 is provided with a second through hole 301 for accommodating the electrode sheets 1101 that fall off.

[0046] The first seat body 40 is hingedly connected to a wrench 50. The wrench 50 is connected with a pressing piece 501. The pressing piece 501 is used to press the second clamping piece 30 against the first clamping piece 20, so that the second clamping piece 30 and the first clamping piece 20 maintain a clamping state to clamp the material strip 110.

[0047] The working principle of the above detection device is as follows. The material strip 110 is placed on the second clamping piece 30, so that the electrode sheet 1101 to be detected on the material strip 110 is above the second through hole 301. Then, the first clamping piece 20 is placed, so that the material strip 110 is located between the first clamping piece 20 and the second clamping piece 30, and the electrode sheet 1101 is exposed at the first through hole 201. Then, the wrench 50 is turned, so that the pressing piece 501 thereof is pressed against the upper part of the first clamping piece 20, thereby causing the first clamping piece 20 and the second clamping piece 30 to clamp the material strip 110. Then, the lifting piece 10 and the punch 101 are driven to move downward relative to the vertical plate 60. At this time, the first elastic piece 102 is gradually stretched. When the punch 101 passes through the first through hole 201 and contacts the electrode sheet 1101 on the material strip 110, the tension F1 of the first elastic piece 102 displayed by the force gauge at this time is recorded. The lifting piece 10 continues to be driven to move downward until the punch 101 punches off the electrode sheet 1101 from the material strip 110. The electrode sheet 1101 that falls off falls into the second through hole 301. The tension F2 of the first elastic piece 102 at this time is recorded. The difference between F2 and F1 is calculated to obtain the force required to punch off the electrode sheet 1101, that is, the force required for the electrode sheet 1101 and the material strip 110 to separate. If the measurement result is within the set threshold range, it indicates that it is qualified. Otherwise, it is considered unqualified. It can be understood that a few electrode sheets on the material strip can be randomly selected for detection. If the detection is qualified, the material strip is considered qualified.

[0048] It can be understood that the axes of the first through hole 201, the second through hole 301, the punch 101 and the electrode sheet 1101 to be detected are preferably coincident, so as to more accurately measure the force required when the measured electrode sheet 1101 and the material belt 110 are separated. The second through hole 301 is also close to one end of the material belt 110, which provides a certain stamping space for stamping.

[0049] The first elastic member 102 is preferably a spring, and can also be an elastic sheet or other elastic element.

[0050] The electrode sheet 1101 can be a negative electrode sheet of a button cell or an electrode sheet 1101 of other types of batteries.

[0051] In some embodiments, the lifting member 10 has a receiving cavity 103 inside, the first plate body 104 is connected in the receiving cavity 103, the first elastic member 102 is located in the receiving cavity 103, one end of the first elastic member 102 is connected with the first plate body 104, and the other end is connected with the force gauge through the traction member 80.

[0052] The first plate body 104 and the lifting member 10 are an integral whole, and both perform lifting movement together.

[0053] The traction member 80 can be a rope, a pull rod or other components that can play a traction role.

[0054] By arranging the first elastic member 102 inside the lifting member 10, it is more conducive to arranging the punch 101 and the slide rail outside the lifting member 10, avoiding interference, and also protecting the first elastic member 102 from external impurities.

Figure 4 When the electrode sheet 1101 on the material belt 110 is punched and falls off by the punch 101, it will fall on the material pushing member 100 in the second through hole 301, and when the punching is finished, the lifting member 10 is driven to rise, the material pushing member 100 will drive the electrode sheet 1101 to rise together, and when the electrode sheet 1101 is exposed outside the second clamping member 30, the electrode sheet 1101 can be taken off.

[0057] It should be noted that the first plate body 104, the first support 90 and the material pushing piece 100 are fixed together and move together with the lifting piece 10, and the material pushing piece 100 does not contact the material belt 110 when the punch 101 punches the electrode sheet 1101 on the material belt 110, so as to ensure the accuracy of detection.

Through the setting of the top cover 105, on the one hand, the first elastic piece 102 can be better protected, and on the other hand, the setting of the lead hole 1051 can play a certain guiding role, so as to avoid the deflection of the first elastic piece 102.

[0061] In some embodiments, the outer side of the lifting piece 10 is connected with the punch 101, and the other outer side of the lifting piece 10 is provided with a first sliding groove 106. The vertical plate 60 is connected with a first sliding rail 601, and the first sliding rail 601 is slidably connected in the first sliding groove 106, so as to ensure the stability and reliability of the lifting piece 10.

[0062] In some embodiments, as shown in Figure 4 The lower pressing piece 501 includes a screw rod part 5011 and a pressing part 5012 connected in sequence from top to bottom, and the pressing part 5012 is used for pressing on the upper surface of the first clamping piece 20. The wrench 50 is provided with a threaded hole 5031, and the screw rod part 5011 is connected with the threaded hole 5031 through threads, which is more convenient for adjusting the extension length of the lower pressing piece 501, so as to be suitable for material belts 110 with different thicknesses.

[0063] Further, the upper part of the first through hole 201 is provided with a tapered counterbore 2011, so as to be more conducive to the smooth and accurate entry of the punch 101 into the first through hole 201 of the first clamping piece 20.

[0064] In some embodiments, one end of the lifting member 10 is provided with an extension plate 107, and a punch 101 is detachably connected to the extension plate 107, so as to facilitate the installation and adjustment of the punch 101.
