Description

Technical Field

[0001] The utility model relates to the technical field of battery baking, in particular to a power battery vacuum baking probe docking heating mechanism. Background Art

[0002] In the production process of power batteries, it is necessary to strictly control the water content inside them. Therefore, generally, the material frame containing the power battery is transported and placed in a baking furnace for vacuum baking. In the vacuum baking furnace, the probe board inside the baking furnace is docked with the contact board on the material frame to achieve power-on heating. In the prior art, the probes on the probe board and the contacts on the contact board are directly and strongly docked under high pressure in the high-temperature baking area. However, when the probes and the contacts are docked, there may be deviations in the in-plane position (this deviation may be caused by inconsistent processing and installation, wear of components after long-term use, etc.), which is likely to result in incomplete contact, leading to discharge and burning out of the probes and short circuit of the circuit; secondly, there may be angular tilt deviations between the probe board and the contact board in space (this deviation may be caused by inconsistent processing and installation, wear of components after long-term use, etc.), resulting in poor contact during docking, leading to discharge and burning out of the probes and short circuit of the circuit; moreover, the docking of the probes and the contacts is directly under high pressure in a vacuum environment, which may cause vacuum discharge and burning out of the probes and short circuit of the circuit. Therefore, the existing probe docking heating mechanism has problems in the accuracy, stability, and safety of docking.

[0003] Therefore, it is necessary to provide at least a power battery vacuum baking probe docking heating mechanism that can automatically correct the angle between the probe board and the contact board in space to improve the accuracy, stability, and safety of docking.

[0007] Preferably, the end of the rotation angle limiting member inserted into the arc-shaped limiting groove is in a spherical structure.

[0008] Preferably, a pin is provided on the probe plate, and a jack is provided on the contact plate. When the lifting floating adaptive mechanism drives the probe plate to rise, the pin is inserted into the jack.

[0023] In order to elaborate on the technical content and structural features of the present utility model in detail, the following further description is made in conjunction with the embodiments and with reference to the drawings.

[0024] Please refer to Figures 1 to 5 , the docking and heating mechanism 100 of the power battery vacuum baking probe 61 of the present utility model includes a material frame 1, a contact plate 2, a spherical plain bearing 3, a first elastic member 4, a lifting floating adaptive mechanism 5 and a probe board 6. The upper end of the spherical plain bearing 3 is fixed to the bottom of the material frame 1, the lower end of the spherical plain bearing 3 is connected to the contact plate 2, and the contact plate 2 is located below the material frame 1. A plurality of contacts 21 are provided on the contact plate 2; one end of the first elastic member 4 is fixed to the bottom of the material frame 1, and the other end of the first elastic member 4 abuts against the contact plate 2. The first elastic member 4 is used to limit the shaking of the contact plate 2 relative to the material frame 1; the output end of the lifting floating adaptive mechanism 5 is connected to the probe board 6. A plurality of probes 61 corresponding to the contacts 21 one by one are provided on the probe board 6. The lifting floating adaptive mechanism 5 drives the probe board 6 to rise, so that the probe board 6 contacts the contact plate 2 and realizes parallel docking under the action of the spherical plain bearing 3. Specifically, the upper end of the spherical plain bearing 3 is fixed to the bottom of the material frame 1 through a flange 32, but not limited thereto. Among them, the first elastic member 4 can adopt a spring structure, but not limited thereto.

[0025] In the present utility model, a spherical plain bearing 3 is arranged between the contact plate 2 and the material box 1. The upper end of the spherical plain bearing 3 is fixed to the bottom of the material box 1, and the lower end of the spherical plain bearing 3 is connected to the contact plate 2, enabling the contact plate 2 to rotate and adjust the angle in space. When there is an angular inclination deviation between the probe plate 6 and the contact plate 2 in space, the lifting floating adaptive mechanism 5 drives the probe plate 6 to rise, causing the probe plate 6 to contact the contact plate 2. During the contact process, under the action of the spherical plain bearing 3, the contact plate 2 can autonomously rotate and adjust the angle to compensate for the non-parallel angular deviation between the contact plate 2 and the probe plate 6, achieving automatic deviation correction, enabling the probe plate 6 and the contact plate 2 to be parallelly docked, ensuring the reliability of the docking between the probe plate 6 and the contact plate 2, and further ensuring the reliability of the docking between the probe 61 and the contact 21.

[0026] Please refer to Figure 4 and Figure 5 , in an embodiment, an arc-shaped limiting groove 22 is provided on the contact plate 2, and a rotation angle limiting member 31 is provided on the spherical plain bearing 3. The rotation angle limiting member 31 is inserted into the arc-shaped limiting groove 22. Through the cooperation of the rotation angle limiting member 31 and the arc-shaped limiting groove 22, the angular range of the contact plate 2 rotating around the center line of the spherical plain bearing 3 is limited. By limiting the angular range of the contact plate 2 rotating around the center line of the spherical plain bearing 3, the situation that the rotation angle of the contact plate 2 in the plane is too large can be avoided, enabling the contact plate 2 to only rotate within a fixed rotation angle range, thereby preventing the contact plate 2 from freely rotating when the material box 1 runs on the track. At the same time, it does not affect the angular deviation correction of the contact plate 2 in space. Further, the end of the rotation angle limiting member 31 inserted into the arc-shaped limiting groove 22 has a spherical structure, but this is not limited thereto.

[0027] Please refer to Figure 4 and Figure 6 , in an embodiment, a pin 62 is provided on the probe plate 6, and a jack 23 is provided on the contact plate 2. When the lifting floating adaptive mechanism 5 drives the probe plate 6 to rise, the pin 62 is inserted into the jack 23. Further, the upper end of the pin 62 has a conical structure, but this is limited thereto.

[0028] Please refer to Figures 1 to 7, in one embodiment, the lifting floating adaptive mechanism 5 includes a lifting drive module 51. The output end of the lifting drive module 51 is connected to the probe board 6, and the lifting drive module 51 is used to drive the probe board 6 to lift. Among them, the lifting drive module 51 can adopt an existing cylinder structure, but is not limited thereto. Further, the lifting floating adaptive mechanism 5 further includes a lifting mounting member 52, a first sliding guide rail 53, a second sliding guide rail 54 and an elastic limiting member 55. The output end of the lifting drive module 51 is connected to the lifting mounting member 52. The first sliding guide rail 53 is arranged on the lifting mounting member 52. The second sliding guide rail 54 is slidably arranged on the first sliding guide rail 53, and the sliding guiding direction of the second sliding guide rail 54 is perpendicular to the sliding guiding direction of the first sliding guide rail 53. The probe board 6 is slidably arranged on the second sliding guide rail 54. The probe board 6 can be moved and adjusted in the plane direction through the first sliding guide rail 53 and the second sliding guide rail 54. A plurality of elastic limiting members 55 are respectively arranged on the lifting mounting member 52 and are located around the probe board 6. Each elastic limiting member 55 respectively abuts against the probe board 6 to make the probe board 6 stable within a fixed position. Among them, the elastic limiting member 55 can adopt a spring structure, but is not limited thereto.

[0029] The lifting drive module 51 of the lifting floating adaptive mechanism 5 drives the lifting mounting member 52 and the probe board 6 to lift together, so that the plug pin 62 of the probe board 6 is inserted into the jack 23 of the contact board 2. During this process, if there is a deviation in the docking position of the probe board 6 and the contact board 2 in the plane, with the assistance of the first sliding guide rail 53 and the second sliding guide rail 54, the probe board 6 can slide in the plane direction along the sliding guiding directions of the first sliding guide rail 53 and the second sliding guide rail 54 respectively, and at the same time will squeeze the elastic limiting member 55 in the moving direction. Thus, when the probe board 6 is docked with the contact board 2, the probe board 6 can achieve 360-degree adaptive deviation correction in the plane. Therefore, when the material frame 1 is pushed into the baking oven and there is a position deviation, when the plug pin 62 of the probe board 6 is inserted into the jack 23 of the contact board 2, the probe board 6 can automatically and accurately find the center line of the probe 61 of the probe board 6 and the contact 21 of the contact board 2 in real time, ensuring that the probe 61 of the probe board 6 and the contact 21 of the contact board 2 are coaxial before contact docking and power-on heating, further improving the accuracy, stability and safety of the docking.

[0030] Please refer to Figure 2 , Figure 3 and Figure 6, in one embodiment, the probe board 6 is provided with a receiving groove 63 with an upward opening, and the probe 61 is arranged in the receiving groove 63. After the probe board 6 is docked with the contact board 2, the contact board 2 covers the opening of the receiving groove 63. Further, a sealing member 64 is provided on the probe board 6. After the probe board 6 is docked with the contact board 2, the sealing member 64 is sealed between the probe board 6 and the contact board 2, so that the sealing ring seals the area where the probe 61 is docked with the contact 21, isolating it from the oven area in the high-temperature baking. Furthermore, the power battery vacuum baking probe 61 docking heating mechanism 100 of the present utility model further includes a gas guiding box body 7 and a gas guiding pipe 8. The gas guiding box body 7 has a gas guiding cavity 71 with an upward opening. The probe board 6 is installed on the upper part of the gas guiding box body 7 and closes the opening of the gas guiding cavity 71. The output end of the lifting floating adaptive mechanism 5 is connected to the gas guiding box. A through hole 65 communicating the receiving groove 63 and the gas guiding cavity 71 is provided on the probe board 6. One end of the gas guiding pipe 8 is installed on the gas guiding box body 7 and communicates with the gas guiding cavity 71, and the other end of the gas guiding pipe 8 communicates with the external atmospheric pressure. By providing the gas guiding box body 7 and the gas guiding pipe 8, the area where the probe 61 is docked with the contact 21 is communicated with the atmosphere, and high-voltage electricity is docked in the communication area. The high-voltage electricity does not need to be stepped down, and there will be no safety accidents such as discharge and blackening, burning out the probe 61 and causing equipment short circuit due to problems such as high-voltage electricity, vacuum, and poor contact during docking.

[0031] Combined with Figures 1 to 7 , the specific working principle of the power battery vacuum baking probe 61 docking heating mechanism 100 of the present utility model is as follows:

[0032] The lifting and lowering drive module 51 of the lifting floating adaptive mechanism 5 drives the lifting and lowering mounting member 52 and the probe board 6 to lift and lower together, so that the plug pin 62 of the probe board 6 is inserted into the jack 23 of the contact board 2. During this process, if there is a deviation in the docking position of the probe board 6 and the contact board 2 in the plane, with the assistance of the first sliding guide rail 53 and the second sliding guide rail 54, the probe board 6 can slide in the plane direction along the sliding guide directions of the first sliding guide rail 53 and the second sliding guide rail 54 respectively, and at the same time, it will squeeze the elastic limiting member 55 in the moving direction. Thus, when the probe board 6 is docked with the contact board 2, the probe board 6 can achieve 360-degree self-adaptive deviation correction in the plane. During this process, when there is an angular inclination deviation between the probe board 6 and the contact board 2 in space, the lifting floating adaptive mechanism 5 drives the probe board 6 to rise, so that the probe board 6 contacts the contact board 2. During the contact process, under the action of the spherical plain bearing 3, the contact board 2 can automatically rotate and adjust the angle to make up for the non-parallel angular deviation between the contact board 2 and the probe board 6, realizing automatic deviation correction and making the probe board 6 and the contact board 2 dock in parallel.

[0033] In summary, the vacuum baking probe 61 of the power battery of the present utility model can automatically correct the angle between the probe board 6 and the contact board 2 in space when docking with the heating mechanism 100. In the plane direction, it can perform 360-degree adaptive correction on the position deviation between the probe board 6 and the contact board 2, fully improving the accuracy, stability, and safety of docking. At the same time, when the contact board 2 runs on the track with the material frame 1, due to the free rotation and rocking angle phenomenon of the spherical plain bearing 3, therefore, by setting the first elastic member 4, the rocking angle phenomenon of the contact board 2 around the center of the spherical plain bearing 3 is restricted. By setting the arc-shaped limiting groove 22 and the rotation angle limiting member 31, the rotation angle of the contact board 2 in the plane is restricted, enabling it to rotate only within a fixed rotation angle, but at the same time not affecting the angle correction of the contact board 2 in space. The probe 61 and the contact 21 are sealed in the docking area by a sealing ring, isolating the docking area from the oven area inside the high-temperature baking. The docking area is connected to the atmosphere, and high-voltage electricity is docked in the communication area. The high-voltage electricity does not need to be stepped down, and there will be no safety accidents such as discharge and blackening caused by problems such as high-voltage electricity, vacuum, and poor contact during docking, which may burn out the probe 61 and cause the equipment to short-circuit.

[0034] The above-disclosed are only the preferred examples of the present utility model, and the scope of rights of the present utility model cannot be limited thereby. Therefore, equivalent changes made according to the claims of the present utility model all fall within the scope covered by the present utility model.
