Description

Technical Field

[0001] The invention relates to the technical field of hot pressing equipment, in particular to a hot pressing machine mechanism with wide compatibility and adaptive automatic adjustment. Background Art

[0002] The battery cell hot pressing equipment mainly applies a certain amount of pressure to the battery cell and processes it at an appropriate temperature. During the hot pressing process, the heat can soften the materials such as the diaphragm and pole piece inside the battery cell, and the pressure helps to remove the air inside the battery cell and make the contact between the pole piece and the diaphragm closer. This is of great significance to improving the performance and safety of the battery cell, for example, it can reduce the internal resistance of the battery cell and enhance the stability of the internal structure of the battery cell.

[0003] In the use of the press machine of the traditional square shell battery cell vertical hot pressing equipment, the battery cell replacement operation is a bit cumbersome. First, the loading fixture must be pulled out of the equipment and the limit assembly on the fixture must be adjusted; then it can be installed on the equipment. Then the probe module must be adjusted and aligned with the position of the battery cell pole before the machine test can be carried out. If the adjustment position is found to be in error during the test process, it needs to be readjusted one by one.

[0004] The existing preparation and adjustment work before battery cell testing is very cumbersome and depends on the workers' proficiency, which increases the labor cost, reduces production efficiency, and cannot meet production needs. Therefore, a hot pressing press mechanism with a wide compatibility range and adaptive automatic adjustment is proposed to solve the above problems. Summary of the invention

[0005] In view of the shortcomings of the prior art, the present invention provides an adaptive and automatically adjustable hot pressing press mechanism with a wide compatibility range, which has the advantage of automatically pressing the battery cells. It solves the problem that the preparation and adjustment work before the existing battery cell test is very cumbersome and depends on the proficiency of the workers, which increases the labor cost, reduces production efficiency, and cannot meet production needs.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a hot pressing machine mechanism with wide compatibility and adaptive automatic adjustment, comprising a positive probe module assembly, a mounting frame assembly, a feeding tool assembly, a negative probe module assembly, a rear positioning assembly and a power push plate mechanism, wherein the positive probe module assembly and the feeding tool assembly are both installed inside the mounting frame assembly, and the positive probe module assembly is located on the top of the feeding tool assembly;

[0007] The loading tooling assembly includes a push-pull handle fixedly installed on one side of the loading tooling assembly, a fixed side clamp plate is fixedly connected to the loading tooling assembly, a movable side clamp plate is slidably connected to the loading tooling assembly, battery cell pads are slidably installed on the opposite sides of the fixed side clamp plate and the movable side clamp plate, and a locking handle is slidably installed on the side of the loading tooling assembly close to the push-pull handle.

[0008] Furthermore, the movable side fixture plate and the locking handle are simultaneously mounted on the same mounting seat, and the locking handle can self-lock the movable side fixture plate at the dead point of the connecting rod between the structures.

[0009] Furthermore, a fixture pad is fixedly connected to a side of the loading tooling assembly away from the movable side fixture plate, and a limit plate is installed on a side of the fixture pad close to the fixed side fixture plate.

[0010] Furthermore, the limit plate is located on one side of the fixed side fixture plate and the movable side fixture plate, and a compression spring push plate is fixedly installed on the top of the fixture pad.

[0011] Furthermore, the negative electrode probe module assembly is installed at the bottom of the feeding tooling assembly, the rear positioning assembly is installed at the back of the feeding tooling assembly, and the power push plate mechanism is installed at the left side of the feeding tooling assembly.

[0012] Furthermore, a driving probe module driving assembly is provided, wherein a module slide rail is fixedly mounted on the front of the probe module, a mounting seat is slidably mounted on the front of the module slide rail, and a compression spring extending to the outside of the mounting seat is slidably connected inside the mounting seat.

[0013] Furthermore, the number of the module slide rails and the number of the mounting seats are both two, the two mounting seats are symmetrically distributed on the front and back of the probe module, and each mounting seat is distributed with two compression springs.

[0014] Furthermore, a probe mounting module is fixedly mounted on the bottom of the probe module, and a nozzle mounting module is mounted on the back of the probe mounting module.

[0015] Furthermore, the compression spring push plate is slidably connected to the compression spring, the compression spring penetrates the compression spring push plate, and the structure of the positive electrode probe module assembly is completely the same as that of the negative electrode probe module assembly.

[0016] Furthermore, the number of probe modules on the positive probe module assembly is the same as the number of fixture pads, and the loading tooling assembly is installed between the positive probe module assembly and the negative probe module assembly.

[0017] Compared with the prior art, the present invention provides a hot pressing machine mechanism with a wide compatibility range and adaptive automatic adjustment, which has the following beneficial effects:

[0018] 1. The adaptive and automatically adjustable hot pressing machine mechanism with a wide compatibility range is convenient for the staff to pull out the loading tooling assembly by setting a push-pull handle, and then by setting a fixed side clamp plate and a movable side clamp plate, it is convenient to adjust the distance between the fixed side clamp plate and the movable side clamp plate according to the width of the battery cell, and then by setting a battery cell pad, the battery cell can be supported and positioned. When the battery cell is pressed down to squeeze the battery cell pad, the fixed side clamp plate and the movable side clamp plate can clamp and fix the battery cell, and then by setting a locking handle, the movable side clamp plate can be self-locked, thereby achieving the effect of fixing the battery cell.

[0019] 2. The hot pressing machine mechanism with wide compatibility and adaptive automatic adjustment can keep the probe module in the middle of two groups of feeding tooling assemblies through the setting of compression springs, under the interaction of the mounting seat and the compression spring push plate on the compression spring. When the power push plate mechanism pushes multiple groups of feeding tooling assemblies to press tightly, the probe module also moves synchronously at the same time and keeps in the center of the two groups of feeding tooling assemblies, realizing the function of adaptive automatic adjustment, solving the problem that the existing preparation and adjustment work before battery cell testing is very cumbersome and depends on the proficiency of the workers, which will increase the labor cost, reduce production efficiency and cannot meet the production needs.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] See also Figures 1 to 4 In this embodiment, a hot pressing machine mechanism with a wide compatibility range and adaptive automatic adjustment includes a positive probe module assembly 1, an installation frame assembly 2, a feeding tool assembly 3, a negative probe module assembly 4, a rear positioning assembly 5 and a power push plate mechanism 6. The positive probe module assembly 1 and the feeding tool assembly 3 are both installed inside the installation frame assembly 2, and the positive probe module assembly 1 is located on the top of the feeding tool assembly 3. The feeding tool assembly 3 includes a push-pull handle 3-8 fixedly installed on one side of the feeding tool assembly 3, a fixed side fixture plate 3-4 is fixedly connected to the feeding tool assembly 3, and a movable side fixture plate 3-5 is slidably connected to the feeding tool assembly 3. The opposite sides of the fixed side fixture plate 3-4 and the movable side fixture plate 3-5 are slidably installed with battery cell pads 3-7, and the side of the feeding tool assembly 3 close to the push-pull handle 3-8 is slidably installed with a locking handle 3-6.

[0027] Among them, the movable side clamp plate 3-5 and the locking handle 3-6 are installed on the same mounting seat at the same time. The locking handle 3-6 can self-lock the connecting rod dead point between the structures of the movable side clamp plate 3-5. The side of the loading tooling assembly 3 away from the movable side clamp plate 3-5 is fixedly connected with a clamp pad 3-2, and the side of the clamp pad 3-2 close to the fixed side clamp plate 3-4 is installed with a limiting plate 3-3.

[0028] It should be noted that the limit plate 3-3 is located on one side of the fixed side clamp plate 3-4 and the movable side clamp plate 3-5, and a compression spring push plate 3-1 is fixedly installed on the top of the clamp pad 3-2. The entire press mechanism loading operation only needs to adjust two places to directly load the battery cells. After the battery cells are loaded, the loading tooling assembly 3 automatically clamps the battery. Under the mutual constraint of the structure, the positive probe module assembly 1 and the negative probe module assembly 4 realize adaptive and automatic adjustment of the center line, so that the probe is always kept in the center of the battery cell. The entire process does not require manual intervention and adjustment.

[0029] It should be noted that the loading fixture assembly 3 is designed into multiple groups according to the required test channels. When the power push plate mechanism 6 presses the multiple groups of loading fixture assemblies 3 to the right side mounting frame assembly 2, the compression spring push plate 3-1 on the loading fixture assembly 3 pushes the positive and negative pole probe modules to the right at the same time. Whenever the battery cell is changed, only the relative width of the fixed side fixture plate 3-4 and the movable side fixture plate 3-5 is adjusted; then the relative height of the battery cell pad 3-7 is adjusted, and then the battery cell is loaded into the loading fixture assembly 3, and finally the loading fixture assembly 3 is pushed to the center of the press mechanism to start the test directly.

[0030] In this embodiment, the negative electrode probe module assembly 4 is installed at the bottom of the feeding tooling assembly 3, the rear positioning assembly 5 is installed at the back of the feeding tooling assembly 3, and the power push plate mechanism 6 is installed on the left side of the feeding tooling assembly 3.

[0031] In this embodiment, the positive probe module assembly 1 includes a probe module 1-2 and a probe module driving assembly 1-1 capable of driving the probe module 1-2. A module slide rail 1-2-1 is fixedly installed on the front of the probe module 1-2. A mounting seat 1-2-2 is slidably installed on the front of the module slide rail 1-2-1. The mounting seat 1-2-2 is internally slidably connected to a compression spring 1-2-3 extending to the outside thereof. There are two module slide rails 1-2-1 and two mounting seats 1-2-2. The two mounting seats 1-2-2 are symmetrically distributed on the front and back of the probe module 1-2, and each mounting seat 1-2-2 is distributed with two compression springs 1-2-3.

[0032] Among them, a probe installation module 1-2-4 is fixedly installed on the bottom of the probe module 1-2, a nozzle installation module 1-2-5 is installed on the back of the probe installation module 1-2-4, the compression spring push plate 3-1 is slidingly connected with the compression spring 1-2-3, the compression spring 1-2-3 runs through the compression spring push plate 3-1, and the structure of the positive probe module assembly 1 and the negative probe module assembly 4 are exactly the same.

[0033] It should be noted that the number of probe modules 1-2 on the positive probe module assembly 1 is the same as the number of fixture pads 3-2. The loading tooling assembly 3 is installed between the positive probe module assembly 1 and the negative probe module assembly 4. The probe module 1-2 is designed as a multi-module assembly mode. In the case of function replacement, such as replacing the equipment with the capacity division test function to the formation function, it is only necessary to pull out the probe installation module 1-2-4, and then install the nozzle installation module 1-2-5 on the probe installation module 1-2-4 to realize the function replacement. Whether it is battery cell loading or function replacement, it is simpler and more convenient than traditional vertical hot pressing equipment, the time of manual participation is reduced, and the function is more automatic and intelligent.

[0034] When the present embodiment is in use, when the specifications of the battery cell are changed, first pull the push-pull handle 3-8 to pull the loading tooling assembly 3 out of the center of the press, then adjust the relative widths of the fixed side clamp plate 3-4 and the movable side clamp plate 3-5 according to the width of the new battery cell, and then adjust the relative height of the battery cell pad 3-7. After the adjustment is completed, insert the new battery downwardly into the battery cell against the limit plate 3-3. After the battery cell contacts the battery cell pad 3-7, the movable side clamp plate 3-5 is pressed against the battery cell under the action of the battery cell's own gravity. At this time, swing the locking handle 3-6 toward the movable side clamp plate 3-5 to achieve self-locking of the connecting rod dead point between the structures.

[0035] After the battery cells are loaded, push the loading tooling assembly 3 toward the center of the press and to the position defined by the rear positioning assembly 5. Then, start the equipment directly. Driven by the motor, the power push plate mechanism 6 approaches the loading tooling assembly 3 to the right. When the power push plate mechanism 6 presses multiple groups of loading tooling assemblies 3 to the right side of the mounting frame assembly 2, the compression spring push plate 3-1 on the loading tooling assembly 3 pushes the positive and negative probe modules 12 to the right side at the same time. After the battery cells are pressed, the positive probe module assembly 1 and the negative probe module assembly 4 are pressed against the loading tooling assembly 3 at the same time to start the test.

[0036] The electrical components appearing in the article are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device for control such as a computer, and the existing public power connection technology is not described in detail in the article.
