[0010] In the pressurizing device provided in the embodiment of the present application, a quick-change connector is provided on the pressurizing tool and the pressurizing mechanism includes a positioning assembly. The positioning assembly can connect the quick-change connector to connect the pressurizing tool to the pressurizing mechanism, and the positioning assembly can also release the quick-change connector to separate the pressurizing tool from the pressurizing mechanism. Therefore, the pressurizing device can easily disassemble and install the pressurizing tool to automatically replace the pressurizing tool so that the pressurizing device can adapt to different batteries. The pressurizing device can quickly replace the pressurizing tool, which is convenient and fast, reduces manual labor intensity, and solves the problems of difficulty and low efficiency in manually replacing pressurizing tools in the prior art. At the same time, since the pressurizing device is compatible with different pressurizing tools to adapt to different types of batteries, the equipment utilization rate is improved and can meet the production needs of different products.

[0011] In some embodiments, the quick-change connector protrudes along the first direction on one side of the second pressure plate, and a positioning hole is provided in the quick-change connector; the positioning assembly includes a first positioning member and a first driving member connected to each other, and the first driving member is used to drive the first positioning member to move along the second direction so that the first positioning member is passed through the positioning hole, and the second direction intersects with the first direction.

[0012] By adopting the above technical solution, the first positioning member in the positioning assembly can be inserted into the positioning hole of the quick-change connector to position the quick-change connector. The positioning assembly has a simple structure and is easy to control.

[0013] In some embodiments, the quick-change connector includes a positioning frame having the positioning hole and a guide member connected to the positioning frame, and the first positioning member can be supported against the guide member.

[0014] By adopting the above technical solution, since the first positioning member can be supported by the guide member, the first positioning member can be clamped with the guide member to position the first positioning member and the quick-change connector relative to each other, so that the quick-change connector is stably connected to the pressurizing mechanism.

[0015] In some embodiments, the first positioning member includes a wedge-shaped portion and the wedge-shaped portion can be abutted against the guide member, and the thickness of the wedge-shaped portion in the first direction gradually decreases from an end close to the first driving member to an end away from the first driving member.

[0073] During the manufacturing process of power batteries, pressurizing equipment is required to pressurize the battery cells after they are glued and placed in the box, so that the glue at the bottom of the battery cells and the box can be firmly bonded together.

[0074] Research has found that there are many types of battery modules, and for battery modules of different sizes, suitable pressurizing tools are needed to achieve pressurization. Currently, the removal and installation of pressurizing tools are usually completed manually. However, manual disassembly and installation are difficult and the replacement efficiency is low.

[0075] In order to solve the problem of disassembly and assembly of a pressurized tool, the present application designs a pressurizing device and a pressurizing equipment. The pressurizing device includes a pressurizing mechanism and a pressurizing tool. The pressurizing mechanism includes a first pressure plate with a through hole and a positioning assembly provided on the first pressure plate; the pressurizing tool includes a second pressure plate and a quick-change connector protruding from the second pressure plate. The quick-change connector can pass through the through hole, and the positioning assembly can connect or release the quick-change connector.

The positioning assembly can connect the quick-change connector to connect the pressurizing tool to the pressurizing mechanism, and the positioning assembly can also release the quick-change connector to separate the pressurizing tool from the pressurizing mechanism. Therefore, the above-mentioned pressurizing device can automatically disassemble and install the pressurizing tool to automatically replace the pressurizing tool, so that the pressurizing device can adapt to different workpieces. The above-mentioned pressurizing device solves the problems of difficulty and low efficiency in manually replacing pressurized tooling in the prior art.

[0076] The pressurizing device and pressurizing equipment provided in this application are described in detail below in conjunction with the embodiments of this application.

[0077] Please refer to FIG. 1 , which illustrates a pressurizing device 1 provided in an embodiment of the present application. The pressurizing device 1 includes a pressurizing device 100 .

[0078] 1 to 4 , an embodiment of a first aspect of the present application provides a pressurizing device 100 , which is suitable for pressurizing batteries. It is understandable that the device is also suitable for pressurizing other workpieces.

[0079] The pressurizing device 100 includes a pressurizing mechanism 10 and a pressurizing tool 20. The pressurizing mechanism 10 includes a first pressure plate 11 with a through hole 111 and a positioning assembly 12 arranged on the first pressure plate 11; the pressurizing tool 20 includes a second pressure plate 21 and a quick-change connector 22 protruding from the second pressure plate 21; the quick-change connector 22 can pass through the through hole 111, and the positioning assembly 12 can connect or release the quick-change connector 22.

[0080] The pressurizing mechanism 10 is a mechanism for providing pressure to the battery, and the pressurizing tool 20 is a fixture that is detachably connected to the pressurizing mechanism 10. One side of the pressurizing tool 20 is connected to the pressurizing mechanism 10, and the other side is used to abut against the battery, so that the pressurizing tool 20 can apply the pressure provided by the pressurizing mechanism 10 to the battery. The pressurizing tool 20 is a replaceable structure, and when in use, an appropriate pressurizing tool 20 can be selected according to the structure of the battery to be pressurized. For example, the battery includes a box body and a plurality of battery cells arranged in the box body. The pressurizing tool 20 is provided with a pressure strip, which is used to press on the shoulder of the battery cell. Therefore, for different types of batteries, the arrangement order of the battery cells is different, and different pressurizing tools 20 are required.

[0081] The pressurizing mechanism 10 includes a first press plate 11 and a positioning assembly 12 disposed on the first press plate 11. The first press plate 11 is used to transmit pressure to the battery via the pressurizing fixture 20. The first press plate 11 can be a plate, frame, or other structure, as long as it can connect to and drive the pressurizing fixture 20. The first press plate 11 can be connected to a pressurizing drive mechanism 40, which can drive the first press plate 11 up and down along a first direction Z to pressurize the battery.

[0082] A through hole 111 is defined in the first pressing plate 11 . The through hole 111 passes through two opposite sides of the first pressing plate 11 along the first direction Z. The through hole is used for the quick-change connector 22 to pass through.

[0083] The positioning assembly 12 is disposed adjacent to the through-hole 111 and is used to connect or release the quick-change connector 22. When the positioning assembly 12 is connected to the quick-change connector 22, the pressurizing tool 20 can be connected to the pressurizing mechanism 10; when the positioning assembly 12 releases the quick-change connector 22, the pressurizing tool 20 can be separated from the pressurizing mechanism 10 to remove the pressurizing tool 20. Specifically, the positioning assembly 12 can be connected to the quick-change connector 22 by means of clamping, clamping, magnetic adsorption, vacuum adsorption, etc. The number of positioning assemblies 12 can be one or more, for example, positioning assemblies 12 are disposed in a one-to-one correspondence with quick-change connectors 22, or every two positioning assemblies 12 are connected to one quick-change connector 22.

[0084] The pressurizing tooling 20 includes a second press plate 21 and a quick-change connector 22 protruding from the second press plate 21. The second press plate 21 can be fitted with the first press plate 11 so that the pressurizing mechanism 10 can drive the pressurizing tooling 20 to press down the battery. The second press plate 21 can be a plate-shaped, frame-shaped or other structure, as long as the second press plate 21 can press down the battery.

[0085] The quick-change connector 22 is used to connect to the positioning assembly 12. It can be understood that in order to enable the pressurizing mechanism 10 to easily install the pressurizing tooling 20, different types of pressurizing tooling 20 can have the same quick-change connector 22, that is, the quick-change connector 22 can be a standard part; or, there are multiple types of positioning assemblies 12, as long as the quick-change connector 22 can be connected to the corresponding positioning assembly 12.

[0086] The working principle of the pressurizing device 100 is as follows: First, the pressurizing fixture 20 is placed on one side of the first pressure plate 11, and the quick-change connector 22 is passed through the through-hole 111 on the first pressure plate 11 and extends to the other side of the first pressure plate 11; then, the positioning assembly 12 connects the quick-change connector 22 to connect the second pressure plate 21 to the first pressure plate 11; during pressurization, the first pressure plate 11 can apply pressure to the battery through the second pressure plate 21 to complete the downward pressure action. When it is necessary to pressurize another type of battery, the positioning assembly 12 releases the quick-change connector 22 to separate the pressurizing fixture 20 from the pressurizing mechanism 10; then, another pressurizing fixture 20 is connected to the pressurizing mechanism 10.

[0087] In the pressurizing device 100 provided in the embodiment of the present application, a quick-change connector 22 is provided on the pressurizing tool 20 and the pressurizing mechanism 10 includes a positioning assembly 12. The positioning assembly 12 can connect the quick-change connector 22 to connect the pressurizing tool 20 to the pressurizing mechanism 10. The positioning assembly 12 can also release the quick-change connector 22 to separate the pressurizing tool 20 from the pressurizing mechanism 10. Therefore, the pressurizing device 100 can easily disassemble and install the pressurizing tool 20 to automatically replace the pressurizing tool 20, so that the pressurizing device 100 can adapt to different batteries. The pressurizing device 100 can quickly replace the pressurizing tool 20, which is convenient and fast, reduces manual labor intensity, and solves the problem of difficulty and low efficiency in manually replacing the pressurizing tool 20 in the prior art. At the same time, because the pressurizing device 100 is compatible with different pressurizing tools 20 to adapt to different types of batteries, the equipment utilization rate is improved and the production needs of different products can be met.

[0088] Please refer to Figures 3 and 4. In some embodiments, the quick-change connector 22 is protruded on one side of the second pressure plate 21 along the first direction Z, and a positioning hole 221 is provided in the quick-change connector 22; the positioning assembly 12 includes a first positioning member 121 and a first driving member 122 connected to each other, and the first driving member 122 is used to drive the first positioning member 121 to move along the second direction X so that the first positioning member 121 is passed through the positioning hole 221, and the second direction X intersects with the first direction Z.

[0089] The first direction Z may be a vertical direction, and the second direction X may be a horizontal direction. In this case, the second direction X is perpendicular to the first direction Z. In other embodiments, the second direction X may also be arranged at other angles to the first direction Z.

[0090] Specifically, the pressurizing fixture 20 is disposed on one side of the first pressure plate 11 along the first direction Z, and the quick-change connector 22 protrudes from one side of the second pressure plate 21 along the first direction Z. Therefore, when the pressurizing fixture 20 and the pressurizing mechanism 10 are brought into close proximity, the quick-change connector 22 can pass through the through-hole 111 in the first pressure plate 11. A positioning hole 221 is defined in the quick-change connector 22 for mating with the first positioning member 121. The positioning hole 221 can be a through hole, or in other embodiments, a blind hole.

[0091] The positioning assembly 12 includes a first positioning member 121 and a first driving member 122 connected to each other. The first driving member 122 is used to drive the first positioning member 121 to move along the second direction X, so that the first positioning member 121 passes through the positioning hole 221 .

[0092] The first driving member 122 can be a cylinder, or it can be other driving members such as an oil cylinder, a ball screw structure, etc. The first driving member 122 is used to drive the first positioning member 121 to move along the second direction X so that the first positioning member 121 is close to or away from the quick-change connector 22; the first positioning member 121 is used to connect and position the quick-change connector 22, and the first positioning member 121 can be a plate-shaped, block-shaped, cylindrical or other structure.

[0093] When the first driving member 122 drives the first positioning member 121 to move toward the quick-change connector 22, the first positioning member 121 can be inserted into the positioning hole 221 to connect the pressurizing tool 20 to the pressurizing mechanism 10; when the first driving member 122 drives the first positioning member 121 to move in a direction away from the quick-change connector 22, the first positioning member 121 can be disengaged from the positioning hole 221 to allow the positioning assembly 12 to release the quick-change connector 22.

[0094] By adopting the above technical solution, the first positioning member 121 in the positioning assembly 12 can be inserted into the positioning hole 221 of the quick-change connector 22 to position the quick-change connector 22. The positioning assembly 12 has a simple structure and is easy to control.

[0095] 4 to 6 , in some embodiments, the quick-change connector 22 includes a positioning frame 222 with a positioning hole 221 and a guide member 223 connected to the positioning frame 222 . The first positioning member 121 can abut against the guide member 223 .

[0096] The positioning frame 222 can be a rectangular frame, a circular frame or a frame of other shapes. The positioning hole 221 is opened in the positioning frame 222 . The first positioning member 121 can be inserted into the positioning hole 221 , so that the first positioning member 121 can be connected to the positioning frame 222 .

[0097] The guide member 223 is connected to the positioning frame 222 , wherein the guide member 223 can be disposed in the positioning hole 221 or outside the positioning hole 221 , for example, on one side of the positioning hole 221 along the second direction X. In the embodiment shown in FIG. 4 , the guide member 223 is disposed in the positioning hole 221 .

[0098] Since the first positioning member 121 can abut against the guide member 223 , the first positioning member 121 can be locked with the guide member 223 to position the first positioning member 121 and the quick-change connector 22 relative to each other, so that the quick-change connector 22 is stably connected to the pressurizing mechanism 10 .

[0099] In some embodiments, the first positioning member 121 includes a wedge-shaped portion 1211 and the wedge-shaped portion 1211 can be supported against the guide member 223 , and the thickness of the wedge-shaped portion 1211 in the first direction Z gradually decreases from the end close to the first driving member 122 to the end away from the first driving member 122 .

[0100] The first positioning member 121 includes a wedge-shaped portion 1211. Specifically, one end of the first positioning member 121 along the second direction X is connected to the first driving member 122, and the end of the first positioning member 121 away from the first driving member 122 may be the wedge-shaped portion 1211; in other embodiments, the wedge-shaped portion 1211 may also be provided at any end or the middle of the first positioning member 121.

[0101] The thickness of the wedge-shaped portion 1211 in the first direction Z gradually decreases from an end close to the first driving member 122 to an end away from the first driving member 122 , wherein the thickness of the wedge-shaped portion 1211 refers to the thickness of the wedge-shaped portion 1211 in the first direction Z.

[0102] When the first driving member 122 drives the first positioning member 121 to move along the second direction X toward the positioning frame 222, the gap between the wedge-shaped portion 1211 and the guide member 223 in the first direction Z gradually decreases. When the first positioning member 121 moves to the preset position, the wedge-shaped portion 1211 can abut against the guide member 223, so that the wedge-shaped portion 1211 and the guide member 223 can abut against each other and position themselves, thereby achieving a fixed connection between the first positioning member 121 and the quick-change connector 22. Since the wedge-shaped portion 1211 and the guide member 223 abut against each other in the first direction Z, the first positioning member 121 can position the quick-change connector 22 in the first direction Z. Since the thickness of the wedge-shaped portion 1211 gradually changes, when the wedge-shaped portion 1211 moves along the second direction X to a position where it abuts against the guide member 223, it will no longer be able to move in the second direction X. In this way, the first positioning member 121 can still position the quick-change connector 22 in the second direction X.

[0103] By adopting the above technical solution, the wedge-shaped portion 1211 of the first positioning member 121 can be abutted against the guide member 223 to achieve a fixed connection between the first positioning member 121 and the quick-change connector 22, so that the pressurizing tooling 20 can be stably connected to the pressurizing mechanism 10; by coordinating and connecting the wedge-shaped portion 1211 with the guide member 223, the positioning of the quick-change connector 22 in the first direction Z and the second direction X can be achieved simultaneously, thereby improving the positioning accuracy.

[0104] Continuing with Figures 4 to 6 , in some embodiments, the guide member 223 is a guide wheel rotatably disposed within the positioning hole 221. The axial direction of the guide wheel is parallel to the third direction Y, which intersects the second direction X and the first direction Z. In this embodiment, the axial direction of the guide wheel is perpendicular to both the second direction X and the first direction Z. Specifically, the guide wheel is rotatably connected to the positioning frame 222 via a rotating shaft.

[0105] When the first positioning member 121 moves within the positioning hole 221, the guide wheel can be in rolling connection with the first positioning member 121, reducing the friction force on the first positioning member 121 and facilitating smooth movement of the first positioning member 121. Because the guide wheel is disposed within the positioning hole 221, when the wedge-shaped portion 1211 abuts against the guide wheel, the first positioning member 121 can be stably connected to the quick-change connector 22.

[0106] As shown in FIG. 4 , in some embodiments, the guide member 223 is disposed on a side of the first positioning member 121 away from the first pressure plate 11 ; it is understood that the guide member 223 may also be disposed on a side of the first positioning member 121 toward the first pressure plate 11 .

[0107] In other embodiments, the guide member 223 may also be a wedge-shaped block or a rectangular block disposed in the positioning hole 221 .

[0108] By configuring the guide member 223 as a rotatable guide wheel, it is facilitated for the first positioning member 121 to move smoothly in the positioning hole 221 .

[0109] In some embodiments, a guide structure 112 extending along the second direction X is provided on the first pressing plate 11 , and the first positioning member 121 is slidably connected to the guide structure 112 .

[0110] The guide structure 112 can be disposed on one side of the through hole 111 along the second direction X; the guide structure 112 can also be disposed above the through hole 111. In this case, the width of the guide structure 112 along the third direction Y is smaller than the width of the positioning frame 222 to prevent obstruction of the quick-change connector 22 from passing through the through hole 111. The guide structure 112 can be a structure such as a slide rail or a slide groove. For example, the guide structure 112 can be provided with a slide groove, and the first positioning member 121 can be provided with a slide rail on the side facing the guide structure 112. The first positioning member 121 can move along the guide structure 112 along the second direction X.

[0111] When the first positioning member 121 moves along the second direction X, the guide structure 112 can constrain the movement direction of the first positioning member 121, and the first positioning member 121 is not easy to float in the first direction Z; accordingly, when the first positioning member 121 moves in the positioning hole 221, since the first positioning member 121 includes a wedge-shaped portion 1211, the positioning frame 222 can float upward along the first direction Z, thereby making the second pressure plate 21 close to the first pressure plate 11.

[0112] By adopting the above technical solution, the guide structure 112 can not only constrain the movement direction of the first positioning member 121 and improve the movement accuracy of the first positioning member 121, but also enable the second pressure plate 21 to be tightly attached to the first pressure plate 11 along the first direction Z, thereby facilitating the downward pressing of the battery.

[0113] As shown in FIG. 4 , in some embodiments, the positioning assembly 12 further includes a floating joint 123 connected between the first driving member 122 and the first positioning member 121 .

[0114] Specifically, one end of the floating joint 123 is connected to the drive shaft of the first driving member 122, and the other end is connected to the first positioning member 121. The first driving member 122 is a driving cylinder. The floating joint 123 functions to reduce the eccentricity of the driving cylinder, ensuring stable operation within the allowable eccentricity range, resolving the problem of insufficient balancing accuracy, and maintaining smooth operation of the driving cylinder.

[0115] In some embodiments, the positioning assembly 12 further includes a position sensor 124 disposed on the first pressure plate 11 . The position sensor 124 is electrically connected to the first driving member 122 and is used to detect the position of the floating joint 123 .

[0116] The position sensor 124 can be of various types, such as a contact sensor or a proximity sensor. The position sensor 124 can detect the position of the floating joint 123 and send a detection signal to the first driving member 122 or a controller for controlling the pressurizing device 100. The first driving member 122 can then control the movement of the first positioning member 121 based on the detection signal.

[0117] By adopting the above technical solution, the first driving member 122 can control the movement of the first positioning member 121 according to the detection signal of the position sensor 124, thereby improving the control accuracy and further improving the alignment accuracy between the pressurizing tool 20 and the battery.

[0118] Please continue to refer to Figures 4 to 6. In some embodiments, a limiting structure 1212 is provided on the side of the first positioning member 121 facing away from the first pressure plate 11; the positioning assembly 12 also includes a second positioning member 125 and a second driving member 126 connected to each other, and the second driving member 126 is used to drive the second positioning member 125 to move along the first direction Z so that the second positioning member 125 is clamped with the limiting structure 1212.

[0119] The second positioning member 125 can be a retaining block, retaining pin, retaining slot, or any other suitable form, as long as it can be easily retained by the limiting structure 1212. In this embodiment, the limiting structure 1212 is a retaining slot, and the second positioning member 125 is provided with a retaining portion that can be received and retained within the limiting slot. In other embodiments, the limiting structure 1212 can also be a retaining protrusion, and the second positioning member 125 can be provided with a retaining slot. The second driving member 126 can be a pneumatic cylinder, an oil cylinder, a ball screw structure, or the like.

[0120] Optionally, when the limiting structure 1212 is a limiting groove, two side walls of the limiting groove along the second direction X may be inclined surfaces, so as to facilitate the second positioning member 125 to be smoothly inserted into the limiting groove.

[0121] Optionally, a mounting bracket 127 is provided on the first pressure plate 11, and the mounting bracket 127 is provided on one side of the through hole 111 along the second direction X. The second driving member 126 is installed on the mounting bracket 127 and the second positioning member 125 is located in the space between the mounting bracket 127 and the first pressure plate 11; the first positioning member 121 can pass through the mounting bracket 127 and the positioning frame 222 in turn, or pass through the positioning frame 222 and the mounting bracket 127 in turn.

[0122] During use, the first positioning member 121 is first moved. When the first positioning member 121 moves to the preset position, the first positioning member 121 can clamp and fix the quick-change connector 22. The second driving member 126 drives the second positioning member 125 to move along the first direction Z, so that the second positioning member 125 and the limiting structure 1212 are mutually clamped. Because the first pressure plate 11 has a certain weight, after the first positioning member 121 fixes the quick-change connector 22, the second positioning member 125 can limit the first positioning member 121, so that the first positioning member 121 is not easy to retract and thus fail to fix the quick-change connector 22.

[0123] By adopting the above technical solution, the second positioning member 125 can limit the first positioning member 121, reducing the probability of the first positioning member 121 retreating. The first positioning member 121 and the second positioning member 125 can jointly position the quick-change connector 22, so that the pressurizing tooling 20 is stably connected to the pressurizing mechanism 10.

[0124] Please refer to Figures 2 and 3. In some embodiments, at least two positioning components 12 are provided on the first pressure plate 11, wherein the two positioning components 12 are diagonally arranged on the first pressure plate 11; at least two quick-change connectors 22 are provided on the second pressure plate 21, wherein the two quick-change connectors 22 are diagonally arranged on the second pressure plate 21.

[0125] The two positioning assemblies 12 are disposed diagonally on the first pressure plate 11, meaning that the two positioning assemblies 12 are spaced apart in the second direction X and spaced apart in the third direction Y. The two positioning assemblies 12 are disposed at two diagonally opposite corners of the first pressure plate 11. Similarly, the two quick-change connectors 22 are disposed at two diagonally opposite corners of the second pressure plate 21.

[0126] By adopting the above technical solution, the pressurizing tool 20 is connected to the first pressing plate 11 through its two diagonal quick-change connectors 22, and the stability after assembly is high, and the structure is simple and the cost is low.

[0127] The number and distribution of the quick-change connectors 22 and the positioning components 12 can be flexibly set. In other embodiments, there can be one quick-change connector 22 and it can be located in the middle of the second pressure plate 21, and the positioning component 12 can be located in the middle of the first pressure plate 11; or, there can be four quick-change connectors 22 and they can be located at the four corners of the second pressure plate 21, and there can be four positioning components 12 and they can be located at the four corners of the first pressure plate 11.

[0128] 2 , in some embodiments, a first positioning pin 211 is provided on the second pressing plate 21 , and a positioning pin hole (not shown) is provided on the first pressing plate 11 . The positioning pin hole cooperates with the first positioning pin 211 to guide the second pressing plate 21 .

[0129] The first positioning pin 211 is protruded from the second pressing plate 21 along the first direction Z. The positioning pin hole can be a through hole or a blind hole. When the second pressing plate 21 moves toward the first pressing plate 11, the first positioning pin 211 can be inserted into the positioning pin hole, thereby guiding the lifting and lowering movement of the second pressing plate 21.

[0130] Optionally, two first positioning pins 211 are provided on the second pressing plate 21 , and the two first positioning pins 211 are diagonally arranged.

[0131] Optionally, the two first positioning pins 211 and the two quick-change connectors 22 are respectively arranged at the four corners of the second pressure plate 21 and are all diagonally arranged, that is, the two first positioning pins 211 are diagonally arranged, and the two quick-change connectors 22 are also diagonally arranged.

[0132] By adopting the above technical solution, the first positioning pin 211 can play a guiding role when installing the second pressing plate 21, thereby improving the alignment accuracy of the second pressing plate 21 and the first pressing plate 11.

[0133] 3 , in some embodiments, the pressurizing device 100 further includes a pressurizing driving mechanism 40 . The pressurizing driving mechanism 40 is connected to the pressurizing mechanism 10 and is used to drive the pressurizing mechanism 10 to move upward and downward.

[0134] The pressurizing drive mechanism 40 is connected to the top of the pressurizing mechanism 10. Under the action of the pressurizing drive mechanism 40, the pressurizing mechanism 10 and the pressurizing tooling 20 are driven to move repeatedly along the first direction Z, thereby applying downward pressure on the battery. The pressurizing drive mechanism 40 can also drive the pressurizing mechanism 10 to rise and fall when replacing the pressurizing tooling.

[0135] The pressurizing drive mechanism 40 can be a pressurizing machine, and can also include a pneumatic cylinder, an oil cylinder, a ball screw structure, etc. By adopting the above technical solution, the pressurizing drive mechanism 40 can drive the pressurizing mechanism 10 and the pressurizing tooling 20 to press down the battery, thereby pressurizing the battery.

[0136] Optionally, the pressurizing drive mechanism 40 may be used in conjunction with a sensor, which can sense the position of the pressurizing mechanism 10 to detect whether the pressurizing mechanism 10 is driven into place.

[0137] Please refer to Figures 1 to 6. Some embodiments of the present application provide a pressurizing device 100, including a pressurizing mechanism 10 and a pressurizing tool 20. The pressurizing mechanism 10 includes a first pressure plate 11 with a through hole 111 and a positioning assembly 12 arranged on the first pressure plate 11. The pressurizing tool 20 is arranged on one side of the pressurizing mechanism 10. The pressurizing tool 20 includes a second pressure plate 21 and a quick-change connector 22 protruding from the second pressure plate 21; the quick-change connector 22 can pass through the through hole 111, and the positioning assembly 12 can connect or release the quick-change connector 22. Among them, the quick-change connecting member 22 includes a positioning frame 222 with a positioning hole 221 and a guide member 223 connected to the positioning frame 222; the pressurizing mechanism 10 includes a first positioning member 121 and a first driving member 122 connected to each other, as well as a second positioning member 125 and a second driving member 126 connected to each other. The first driving member 122 is used to drive the first positioning member 121 to move along the second direction X, so that the first positioning member 121 is inserted into the positioning hole 221, and the wedge-shaped portion 1211 on the first positioning member 121 can be supported by the guide member 223; the second driving member 126 is used to drive the second positioning member 125 to move along the first direction Z, so that the second positioning member 125 is clamped with the limiting structure 1212.

[0138] The pressurizing device 100 provided in this embodiment of the present application can automatically connect or release the quick-change connector 22 to automatically replace the pressurizing tool 20. During cutting, pulling and changing molds, the pressurizing device 100 can improve the efficiency of replacing the pressurizing tool 20 and reduce the difficulty of replacing the pressurizing tool 20, effectively improving production efficiency.

[0139] Please continue to refer to Figure 1. The embodiment of the second aspect of the present application proposes a pressurizing device 1, including the pressurizing device 100 provided in the first aspect and the lifting device 200. The lifting device 200 is used to drive at least one of the pressurizing tooling 20 and the pressurizing mechanism 10 to move, so that the pressurizing tooling 20 is close to or away from the pressurizing mechanism 10.

[0140] Specifically, the lifting device 200 is connected to the pressurizing tool 20 and is used to drive the pressurizing tool 20 to move along the first direction Z to assemble or disassemble the pressurizing tool 20. In other embodiments, the lifting device 200 can also be connected to the pressurizing mechanism 10 and drive the pressurizing mechanism 10 to move along the first direction Z. The lifting device 200 may include a bracket 210 and a lifting assembly 220 provided on the bracket 210. The lifting assembly 220 includes a lifting drive member and a lifting member connected to the lifting drive member. The lifting drive member may be a cylinder for driving the pressurizing tool 20 to rise and fall, and may also include an oil cylinder, a ball screw structure, etc. The lifting member may include a lifting block for lifting the transfer device 300, and may further include components such as a lifting universal ball.

[0141] The pressurizing equipment 1 provided in the embodiment of the present application includes a pressurizing device 100 and a lifting device 200. The pressurizing device 100 can automatically connect or release the pressurizing tooling 20; at the same time, the lifting device 200 can automatically drive the pressurizing tooling 20 and / or the pressurizing mechanism 10 to move, without the need for manual lifting of the pressurizing tooling 20, thereby further improving the degree of automation of the pressurizing equipment 1 and reducing the difficulty of operation.

[0142] Referring to FIG. 1 , in some embodiments, the pressurizing device 1 further includes a transfer device 300 for transferring the pressurizing tool 20 , and the lifting device 200 is used to drive the transfer device 300 to move up and down.

[0143] The transfer device 300 can be a mobile trolley, which can not only carry the pressurizing tooling 20, but also drive the pressurizing tooling 20 to move to the bottom of the pressurizing mechanism 10; the lifting device 200 is used to drive the transfer device 300 to rise and fall, that is, to drive the transfer device 300 and the pressurizing tooling 20 to rise and fall along the first direction Z, so that the pressurizing tooling 20 is close to or away from the pressurizing mechanism 10.

[0144] The pressurizing device 1 further includes a frame 30 , the pressurizing mechanism 10 is disposed on the frame 30 , the lifting device 200 is disposed below the pressurizing mechanism 10 ; and the transfer device 300 can be moved to the bottom of the pressurizing mechanism 10 .

[0145] During use, the transfer device 300 drives the pressurizing tooling 20 to move to the bottom of the pressurizing mechanism 10, and then the lifting device 200 drives the transfer device 300 to rise, so that the second pressure plate 21 is attached to the first pressure plate 11, and the positioning assembly 12 is used to fix the quick-change connector 22, so that the pressurizing tooling 20 is fixed on the pressurizing mechanism 10.

[0146] By adopting the above technical solution, the pressurizing equipment 1 can use the transfer device 300 to transport the pressurizing tool 20, and use the lifting device 200 to lift the transfer device 300 and the pressurizing tool 20, which has a high degree of automation and is easy to use.

[0147] Please refer to Figures 1 and 7A to 9. In some embodiments, the transfer device 300 includes a vehicle body 310 and a support platform 320 provided on the vehicle body 310. The support platform 320 is used to carry and position the pressurizing tooling 20. A universal ball 330 and a second positioning pin 340 are provided on the vehicle body 310. The second positioning pin 340 can be movably passed through the support platform 320. The universal ball 330 is supported on the support platform 320.

[0148] The vehicle body 310 may include a vehicle frame and universal wheels disposed at the bottom of the vehicle frame for easy movement. The support platform 320 is used to support the pressurizing tooling 20 and to position the pressurizing tooling 20 via a second locating pin 340. The vehicle body 310 may include one or more universal balls 330. When there are multiple universal balls 330, the multiple universal balls 330 may be spaced apart. The support platform 320 is disposed on the universal balls 330, so that when the pressurizing tooling 20 is replaced, the support platform 320 can be fine-tuned within a certain range above the universal balls 330, that is, the support platform 320 can be fine-tuned within a horizontal plane. The second locating pin 340 can be movably disposed through the support platform 320 to limit the position of the support platform 320 on the vehicle body 310.

[0149] By adopting the above technical solution, the above-mentioned transfer device 300 can carry and position the pressurizing tooling 20, and the position of the support platform 320 can be fine-tuned, which facilitates the relative positioning of the pressurizing tooling 20 and the pressurizing mechanism 10, and makes it less likely for the pressurizing tooling 20 to get stuck.

[0150] As shown in FIG. 7B , in some embodiments, a connection hole 321 is defined on the support platform 320 , and the second positioning pin 340 is passed through the connection hole 321 . The outer diameter of the second positioning pin 340 is smaller than the inner diameter of the connection hole 321 .

[0151] Since the outer diameter of the second positioning pin 340 is smaller than the inner diameter of the connecting hole, the second positioning pin 340 can move relative to the support platform 320 .

[0152] When assembling the press tool 20 , the support platform 320 can be limited by the second positioning pin 340 and can be fine-tuned on the vehicle body 310 at the same time, thereby reducing the difficulty of positioning and assembling the press tool 20 .

[0153] 1 and 10 , in some embodiments, the pressurizing device 1 further includes a lifting stop mechanism 230 . The lifting stop mechanism 230 is disposed on at least one side of the lifting device 200 and is used to stop the transfer device 300 .

[0154] Optionally, the transfer device 300 can move along the third direction Y below the frame 30 , and the lifting stop mechanism 230 is provided along the third direction Y on at least one side of the lifting device 200 .

[0155] The lifting stop mechanism 230 may include a stop driving member and a stop block connected to each other, wherein the stop driving member is used to drive the stop block to move horizontally to stop the transfer device 300 so that the transfer device 300 does not move any further.

[0156] Optionally, the lifting device 200 includes two groups of relatively arranged lifting components 220, each group of lifting components 220 includes a lifting drive component and a lifting component, and the transfer device 300 can move between the two groups of lifting components 220; there are four lifting stop mechanisms 230 and they are respectively arranged on both sides of the two groups of lifting components 220.

[0157] By adopting the above technical solution, the lifting stop mechanism 230 can limit the movement of the transfer device 300 so that the lifting device 200 can smoothly lift the transfer device 300.

[0158] 1 to 3 , in some embodiments, there are multiple pressurizing tools 20 , which are arranged side by side. Each pressurizing tool 20 is provided with multiple parallel and spaced press heads 212 .

[0159] Specifically, multiple pressurizing fixtures 20 are sequentially arranged along the third direction Y, and the press heads 212 extend along the third direction Y and are sequentially spaced apart along the second direction X. Accordingly, multiple pressurizing mechanisms 10 can be provided and sequentially arranged along the third direction Y, with each pressurizing mechanism 10 corresponding to each pressurizing fixture 20. It is understood that a single pressurizing mechanism 10 can also be connected to multiple pressurizing fixtures 20.

[0160] The battery may include a housing and battery cells disposed within the housing. Multiple battery cells may be assembled into a battery module before being installed within the housing, or they may be installed directly within the housing. The pressing head 212 is capable of pressing against the shoulder of the battery cell. The pressing head 212 may be bar-shaped; in other embodiments, the pressing head 212 may be block-shaped or have other structures.

[0161] By adopting the above technical solution, the pressing heads 212 on the multiple pressing fixtures 20 are arranged in multiple rows. Each row of pressing heads 212 can simultaneously press down a row of battery cells. When the arrangement of battery cells changes, the pressing device 1 can replace the corresponding pressing fixture 20 to achieve cutting, pulling and changing. The row of pressing heads 212 refers to a row of pressing heads 212 arranged along the third direction Y.

[0162] Referring to Figures 1 to 10, some embodiments of the present application provide a pressurizing device 1, comprising a frame 30, a pressurizing mechanism 10 disposed on the frame 30, a lifting device 200 disposed below the frame 30, and a movable transfer device 300. The transfer device 300 can drive the pressurizing tool 20 to move above the lifting device 200, and the lifting device 200 can lift the transfer device 300 to bring the pressurizing tool 20 close to the pressurizing mechanism 10; after the pressurizing mechanism 10 is fixedly connected to the pressurizing tool 20, the lifting device 200 drives the transfer device 300 to descend, and the transfer device 300 withdraws to the outside of the frame 30, completing the mold change and waiting for the pressing operation.

[0163] Optionally, the pressurizing drive mechanism 40 can drive the pressurizing mechanism 10 to descend after the lifting device 200 lifts the transfer device 300 , and can drive the pressurizing mechanism 10 and the pressurizing tooling 20 to ascend after the positioning assembly 12 positions the pressurizing tooling 20 .

[0164] The above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
