Description

Technical Field

[0001] This utility model relates to the field of new energy battery processing technology, and in particular to a copper-aluminum composite plate pressing device. Background Technology

[0002] Aluminum-based copper-clad laminates are made of aluminum plates or aluminum-containing materials as the base material and a thin copper plate is hot-pressed on the surface. Copper-aluminum composite plates are usually used as current collectors in batteries. Their main function is to collect and transmit current. Copper has good electrical conductivity, which can effectively reduce the internal resistance of the battery and improve the charging and discharging efficiency of the battery.

[0003] The production process of copper-aluminum composite panels requires the use of a pressing device. For example, the existing technology disclosed in Chinese Patent Publication No. "CN116442632B" is a copper-aluminum pressing molding equipment and its molding method for aluminum-based copper-clad laminates. By adopting an automatic pressing method, the processing of aluminum-based copper-clad laminates is automated, which can effectively simplify the processing method, improve the automation level of the workshop, improve the production efficiency of aluminum-based copper-clad laminates, and save the use of the supporting high-pressure air supply system, saving costs and simplifying the structure. The equipment includes a pressing box with its opening facing downwards. The left and right side walls of the pressing box are provided with conveying holes, which are close to the top of the pressing box. A guide cylinder is connected to the middle of the top of the pressing box. A hot press plate is vertically slidable inside the guide cylinder. A ring cutter is provided on the outer circumference of the hot press plate. The bottom of the ring cutter is set as a conical cutting edge, and the cutting edge is in contact with the outer wall of the hot press plate.

[0004] In actual operation, the piston plate works with the hot press plate to hot press the copper and aluminum plates. The piston plate positions the copper and aluminum plates through the positioning strip on the top. However, because the positioning strip is fixed to the piston plate, it can only position copper and aluminum plates within a specified size, which limits its applicability. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where the positioning strips can only position copper and aluminum plates within a specified size, and to propose a copper-aluminum composite plate pressing device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A copper-aluminum composite plate pressing device is designed, including a frame, a pressing unit is provided on the top of the frame, the pressing unit includes a support seat, and a positioning component is provided at the bottom of the support seat. The positioning component is used to position the copper-aluminum plate.

[0008] The positioning component includes a positioning element, and the top of the positioning element is provided with an adjustment structure, which is used to abut against the side wall of the copper-aluminum plate.

[0009] Furthermore, the positioning component also includes a bracket, with a sealing cover fixedly connected to the bottom of the support seat. The bracket is fixedly connected inside the sealing cover and has an L-shaped structure. Support members are slidably connected to both ends of the bracket, and each support member consists of a pair of plates.

[0010] Furthermore, the opposite ends of the pair of plates are respectively provided with a protruding structure and the positioning member, and the opposite ends are respectively provided with a T-shaped part and a T-shaped groove. The T-shaped part is slidably connected in the T-shaped groove by a first compression spring provided on the protruding parts on both sides.

[0011] Furthermore, a motor is fixedly connected to the bottom of the sealing cover, and the shaft end of the motor passes through the sealing cover and the bracket in sequence. A connector is also fixedly connected to the shaft end. The connector is provided with an arc groove corresponding to the support member, and the protruding structure is slidably connected in the arc groove.

[0012] Furthermore, the adjustment structure includes a stop and a locking member. The stop is slidably connected in the top groove of the positioning member. The locking member is rotatably connected to the stop through the top recessed hole. The end of the locking member passes through the stop and is threadedly connected to the positioning member.

[0013] A second compression spring is also sleeved around the end of the locking member.

[0014] Furthermore, the abutment is slidably connected in a pair of guide grooves on the end face of the bearing seat, and the outer wall of the copper-aluminum composite plate abuts against the pair of abutment and one side corner of the bearing seat.

[0015] The copper-aluminum composite plate pressing device proposed in this utility model has the following advantages: This utility model is equipped with a positioning structure. Through the motor drive, a pair of support members move synchronously. Then, the positioning member and the abutment member, together with the bearing seat, can position the copper-aluminum plate and prevent the upper and lower plates from shifting during the hot pressing process. In addition, a compatible space is formed between the pair of plates by the setting of the first compression spring to prevent the situation where the support member on one side is stuck to the plate while the support member on the other side does not abut to the plate when the widths on both sides of the copper-aluminum plate are different. Furthermore, the height of the abutment member can be finely adjusted by adjusting the locking member to prevent the hot pressing plate from abutting the abutment member. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-5 A copper-aluminum composite plate pressing device includes a frame 1, a pressing unit 2 is provided on the top of the frame 1, the pressing unit 2 includes a support seat 21, and a positioning component 3 is provided at the bottom of the support seat 21. The positioning component 3 is used to position the copper-aluminum plate.

[0024] The positioning component 3 includes a positioning element 31, and the top of the positioning element 31 is provided with an adjustment structure 4. The adjustment structure 4 is used to abut against the side wall of the copper-aluminum plate. Of course, in this embodiment, the adjustment structure 4 is used to abut against the side wall of square copper-aluminum plates of different thicknesses within a certain range.

[0025] In some embodiments, the pressing unit 2 is a hot pressing mechanism, including a hot pressing plate driven by a lifting device. The hot pressing plate and the support seat 21 are arranged vertically opposite each other, and a heating system is also provided at the bottom of the hot pressing plate. When the hot pressing plate and the support seat 21 are closed, a pair of copper and aluminum plates are hot-pressed and formed by high temperature and high pressure. The specific structure is the prior art and will not be described in detail here.

[0026] Furthermore, the positioning component 3 also includes a bracket 33, which is fixedly connected to a sealing cover 22 at the bottom of the bearing seat 21. The bracket 33 is fixedly connected inside the sealing cover 22. The bracket 33 has an L-shaped structure, and both ends of it are slidably connected to support members. The support members are composed of a pair of plates 34.

[0027] Specifically, the sealing cover 22 is matched with the support seat 21. The sealing cover 22 is fixed to the support seat 21 by locking bolts on both sides, and a sealing gasket is provided between the sealing cover 22 and the support seat 21 to further improve airtightness.

[0028] The sealing cover 22 is used to maintain the airtightness of the bearing seat 21 and the hot press plate after they are molded together, to ensure that the plate is hot-pressed under high temperature and high pressure. In addition, a shaft seal can be provided between the sealing cover 22 and the shaft end of the motor 36 to prevent leakage at the shaft and the housing.

[0029] Furthermore, the opposite ends of the pair of plates 34 are respectively provided with a protruding structure 341 and the positioning member 31, and the opposite ends are respectively provided with a T-shaped part 342 and a T-shaped groove 343. The T-shaped part 342 is slidably connected to the T-shaped groove 343 by a first compression spring 35 provided on the protruding parts on both sides.

[0030] It should be added that a compatible space is formed between a pair of plates 34 by the setting of the first compression spring 35, so as to prevent the situation where the support on one side is stuck to the plate while the support on the other side does not contact the plate when the widths on both sides of the copper and aluminum plates are different.

[0031] More specifically, a motor 36 is fixedly connected to the bottom of the sealing cover 22. The shaft end of the motor 36 passes through the sealing cover 22 and the bracket 33 in sequence, and a connector 32 is also fixedly connected to its shaft end. The connector 32 is provided with an arc groove 321 corresponding to the support member, and the protruding structure 341 is slidably connected in the arc groove 321.

[0032] In specific operation, the motor 36 drives the connector 32 to rotate. While the connector 32 rotates, it drives the protruding structure 341 through the arc groove 321 to extend and retract the plate 34. Then, through the extension and retraction, a pair of abutting parts 41 abut against the outer side walls of the copper and aluminum plate. At the same time, the inner side walls of the copper and aluminum plate abut against the bearing seat 21 to achieve the fixing effect.

[0033] In general, the adjustment structure 4 includes a stop member 41 and a locking member 42. The stop member 41 is slidably connected in the top groove of the positioning member 31. The stop member 41 is rotatably connected to the locking member 42 through the top recessed hole. The end of the locking member 42 passes through the stop member 41 and is threadedly connected to the positioning member 31.

[0034] A second compression spring 43 is also sleeved around the end of the locking member 42.

[0035] In this embodiment, the locking member 42 is an internal hexagon locking bolt. The locking member 42 is rotated with the help of a tool to move it up and down. The height of the abutment member 41 is finely adjusted to prevent the abutment member 41 from contacting the hot press plate.

[0036] Specifically, the two ends of the second compression spring 43 abut against the positioning member 31 and the abutment member 41 respectively, and the second compression spring 43 is used to reset the abutment member 41.

[0037] Finally, the abutment 41 is slidably connected in a pair of guide grooves 23 on the end face of the bearing seat 21, and the outer wall of the copper-aluminum composite plate abuts against the pair of abutment 41 and one side corner of the bearing seat 21 respectively.

[0038] The support base 21 has a rectangular structure.

[0039] Working method: During operation, the copper and aluminum plates are placed on the bearing seat 21. The motor 36 drives the connector 32 to rotate. While the connector 32 rotates, the arc groove 321 drives the protruding structure 341 to extend and retract the plate 34. A pair of abutting parts 41 abut against the outer side walls of the copper and aluminum plates. At the same time, the inner side walls of the copper and aluminum plates abut against the bearing seat 21 to achieve a fixing effect.

[0040] By using a tool to rotate the locking part 42 to move it up and down, and by coordinating the second compression spring 43 to finely adjust the height of the abutment part 41, the abutment part 41 is prevented from contacting the hot pressure plate.

[0041] After the hot press plate moves down and presses against the support seat 21, a pair of plates are pressed together by high temperature and high pressure.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
