Embodiment 1

[0022] Such as figure 1 As shown, a pole piece cutting device with a pressing function of the present invention includes a base 1, a storage plate 2 is installed above the base 1, and a support plate A3 and a support plate B4 are respectively arranged on both sides of the support plate 2, and the support plate There are two circumscribed finale shafts 5 placed in parallel between A3 and support plate B4. One end of the finale shaft 5 is connected to the support plate A3, and the other end of the finale shaft 5 is connected to the support plate B4. The finale shaft 5 is located directly above the middle position of the storage board 2. 5 is connected with the support plate A3 and the support plate B4 through a chute, and the top of the storage plate 2 is also provided with a fixed plate 6 and a cutter 7, and the fixed plate 6 and the cutter 7 are placed in parallel between the support plate A3 and the support plate B4 Between, one end of the cutter 7 is connected with the suppo...

Embodiment 2

[0025] Based on Embodiment 1, a scale 10 is connected to the fixing plate 6 , and the other end of the scale 10 is connected to the cutter 7 . The ruler is used to assist in measuring the width of the pole piece, so that the pole piece strips cut out are more accurate. The scale adopts a stainless steel scale and the measurement length of the scale is just the width of the pole piece. The scale can be replaced according to different pole pieces, and the measurement result is more accurate.

Embodiment 3

[0027] Based on the above embodiment, a control cabinet 11 with a shelf inside is connected to the bottom of the base 1 . The control cabinet 11 is connected with the base 1 through the telescopic column 12, and the telescopic column 12 is covered with a spring 13, one end of the spring 13 is connected with the control cabinet 11, and the other end of the spring 13 is connected with the base 1. The control cabinet can be used to store replacement tools, and the support plate A, support plate B, fixed plate, and cutter can all be replaced; the present invention can realize semi-automation, and can electrically control the sliding of the fixed plate, cutter, and finale. The control systems in the present invention are all arranged in the control cabinet to maintain the integrity of the device. The telescopic column can adjust the height of the base, that is, the height of all parts above the base, and can be used with other lithium-ion battery processing equipment; the spring is...

Abstract

The invention discloses a pole piece strip cutting device with a pressing function. The device comprises a base, wherein a placement plate is mounted above the base; a support plate A and a support plate B are respectively arranged on the two sides of the placement plate; two externally tangent pressing shafts are placed between the support plate A and the support plate B in parallel; one end of each pressing shaft is connected with the support plate A, and the other end of each pressing shaft is connected with the support plate B; the pressing plates are located right above the middle of the placement plate, and are connected with the support plate A and the support plate B through chutes; a fixing plate and a cutter are further arranged above the placement plate and placed between the support plate A and the support plate B in parallel; and one end of the cutter is connected with the support plate A, and the other end of the cutter is connected with the support plate B. The device provided by the invention has the advantages that a pole piece can be kept strained throughout a strip cutting process through the pressing shafts and the fixing plate, so that the pole piece can be prevented from curling or loosing, and a large number of burrs at the edges of a pole piece strip obtained through cutting can be avoided.

Description

technical field [0001] The invention relates to a cutting machine, in particular to a pole piece cutting device with a pressing function. Background technique [0002] Lithium-ion batteries use carbon materials as the negative electrode and lithium-containing compounds as the positive electrode. There is no metallic lithium, only lithium ions. This is the lithium-ion battery. Lithium-ion battery refers to the general term for batteries with lithium-ion intercalation compounds as positive electrode materials. The charging and discharging process of lithium-ion batteries is the intercalation and deintercalation process of lithium ions. During the intercalation and deintercalation process of lithium ions, it is accompanied by the intercalation and deintercalation of electrons equivalent to lithium ions (the positive electrode is customarily represented by intercalation or deintercalation, while the negative electrode is represented by insertion or deintercalation). During the...
