Description

Technical Field

[0002] During the battery pack assembly process, the high-voltage connector must first be installed in the lower shell, and then the upper shell must be installed on the lower shell. A clearance hole that matches the pole of the high-voltage connector is provided on the upper shell. In the process of installing the upper shell on the lower shell, the pole of the high-voltage connector must be aligned with the clearance hole up and down, and the pole of the high-voltage connector must be gradually inserted into the clearance hole of the falling upper shell. Due to the elastic connection between the high-voltage connector and the lower shell, the deadweight of the pole, and the squeezing of the pole by the falling upper shell, the axial direction of the pole is very easy to tilt. Therefore, it is often necessary to use the human hand to straighten the pole so that the pole can smoothly pass through the clearance hole of the upper shell.

[0003] Therefore, how to replace human hands to correct the axial direction of the pole of the high-voltage connector has become a technical problem that needs to be solved urgently by those skilled in the art. Utility Model Content

DETAILED DESCRIPTION

[0032] The technical solution of the utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] It should be noted that the battery pack interacts with the vehicle through a high-voltage connector / low-voltage connector. The high-voltage connector of the battery pack is used to output high-voltage power to the vehicle. Four poles are arranged on the high-voltage connector along the length of the high-voltage connector.

[0034] As described in the background technology, during the assembly of the battery pack, the high-voltage connector must first be installed in the lower shell, and then the upper shell must be installed on the lower shell. A clearance hole that matches the pole of the high-voltage connector is provided on the upper shell. In the process of installing the upper shell on the lower shell, the pole of the high-voltage connector must be aligned with the clearance hole up and down, and the pole of the high-voltage connector must be gradually inserted into the clearance hole of the falling upper shell. However, due to the elastic connection between the high-voltage connector and the lower shell, the deadweight of the pole, and the squeezing of the pole by the falling upper shell, the axial direction of the pole is very easy to tilt. Therefore, it is often necessary to use the human hand to straighten the pole so that the pole can smoothly pass through the clearance hole of the upper shell. Therefore, how to replace the human hand to correct the axial direction of the pole of the high-voltage connector has become a technical problem that needs to be solved urgently by technicians in this field.

[0035] To solve the above problems, refer to Figure 1 , Figure 2 and Figure 3The utility model provides an auxiliary tooling for battery pack assembly, including a guide column 110, a base 120, a correction seat 130 and a correction mechanism 140. The guide column 110 is suitable for being installed on the pole 210 of the high-voltage connector 200, and the axial length of the pole 210 is extended. On the one hand, it is conducive to the pole 210 to penetrate into the clearance hole on the upper shell; on the other hand, the height difference between the pole 210 and the correction seat 130 in the vertical direction is eliminated, and the pole 210 can be attached to the inner wall of the correction groove 131 through the guide column 110. The top surface of the base 120 is used to support the lower shell 300 of the battery pack, the high-voltage connector 200, the correction seat 130 and the correction mechanism 140. The correction seat 130 is installed on the base 120 and can be moved to a position close to or away from the guide column 110. The correction seat 130 is provided with a correction groove 131 adapted to the side wall of the guide column 110. The correction mechanism 140 is installed on the correction seat 130 and can move with the correction seat 130. When the correction seat 130 moves close to the guide column 110, the correction mechanism 140 is actuated to make the side wall of the guide column 110 fit with the inner wall of the correction groove 131, so as to achieve the purpose of correcting the axial direction of the guide column 110. On the whole, it can replace the human hand to correct the axial direction of the pole 210 of the high-voltage connector 200, prevent the human hand from directly contacting the electrical components during assembly, avoid the human hand from being squeezed by the falling upper shell during the correction process, and improve the safety of the correction work. At the same time, it prevents the human hand from contacting the sealing glue pre-coated on the flange surface of the lower shell 300, which is conducive to reducing the risk of local sealing failure. Compared with the form of only using the guide column 110, the axial direction of the guide column 110 is avoided from tilting along with the pole 210, thereby avoiding the phenomenon that the axial tilt of the pole 210 affects the assembly efficiency. At the same time, the axial tilt of the pole 210 is avoided from damaging the internal electrophoretic paint film of the upper shell, thereby ensuring the assembly efficiency, improving the safety of the assembly, and improving the yield of the assembled product.

[0036] Preferably, the top of the guide post 110 is a conical structure, which is conducive to the top of the guide post 110 passing through the clearance hole on the upper shell, and further facilitates the pole 210 to pass through the clearance hole on the upper shell.

[0037] Preferably, the guide post 110 is detachably sleeved on the outside of the pole 210 of the high-voltage connector 200. Before assembly, the guide post 110 can be installed on the pole 210 of the high-voltage connector 200; after assembly, the guide post 110 can be detached from the pole 210 of the high-voltage connector 200. In this way, the guide post 110 can be recycled.

[0038] Preferably, two correction grooves 131 are provided on the correction seat 130. There are two guide posts 110, which are respectively detachably sleeved on two poles 210 at both ends of the high-voltage connector 200. Compared with the form of correcting only one pole 210 in the axial direction, it is more conducive to assembly.

[0039] Specifically, in the exemplary embodiment, the correction seat 130 is located on one side of the guide post 110. A correction groove 131 is provided on the side of the correction seat 130 close to the guide post 110. A clearance groove 133 adapted to the pole 210 is provided on the side of the correction seat 130 close to the guide post 110. The correction mechanism 140 is integrally installed on the side of the correction seat 130 close to the guide post 110, and includes two correction claws 141 and two rotating shafts. Each correction clamp is in a "V" shape as a whole. The middle part of each correction claw 141 is rotatably mounted on the top surface of the correction seat 130 through a rotating shaft. The two correction claws 141 are used to make the side walls of the two guide posts 110 fit tightly with the inner walls of the corresponding correction grooves 131, respectively. When the side walls of the two guide posts 110 are respectively fitted with the inner walls of the corresponding correction grooves 131, the side walls of the two poles 210 without the guide posts 110 are fitted with the inner walls of the clearance grooves 133. The correction seat 130, the correction mechanism 140 and the guide posts 110 cooperate with each other to replace the human hand to correct the axial direction of the pole 210 of the high-voltage connector 200, prevent the human hand from directly contacting the electrical components during assembly, avoid the human hand from being squeezed by the falling upper shell during the correction process, and improve the safety of the correction work. At the same time, it prevents the human hand from contacting the sealing glue pre-coated on the flange surface of the lower shell 300, which is conducive to reducing the risk of local sealing failure. Compared with the form of only using the guide column 110, the axial direction of the guide column 110 is avoided from tilting along with the pole 210, thereby avoiding the phenomenon that the axial tilt of the pole 210 affects the assembly efficiency. At the same time, the axial tilt of the pole 210 is avoided from damaging the internal electrophoretic paint film of the upper shell, thereby ensuring the assembly efficiency, improving the safety of the assembly, and improving the yield of the assembled product.

[0040] In some of the embodiments, the correction mechanism 140 also includes two drivers. The two drivers are respectively installed on the top surface of the correction seat 130, and the output shaft is connected to the two correction claws 141 in a one-to-one correspondence, and is used to drive the two correction claws 141 to rotate respectively. Compared with the form of driving the correction claws 141 to rotate by manpower, it is conducive to improving the degree of automation, thereby making the auxiliary tooling for battery pack assembly more suitable for mass production. Each driver can be a servo electric cylinder, and the servo electric cylinder has higher control accuracy. Each driver can also be an electric push rod, and the electric push rod can control the thrust and speed by adjusting the pitch, which can achieve very precise positioning and motion control. There is no need to use liquid or gas or other working fluids during work, so there will be no problem of hydraulic oil or gas leakage polluting the working environment, and the environmental protection performance is better. At the same time, it is easy to install and the maintenance cost is also low. Of course, the driver can also be a hydraulic cylinder or a cylinder, with a relatively stable power output, faster action, strong reliability, simple structure and low maintenance cost.

[0041] In other embodiments, the correction mechanism 140 includes a driver, which may have two output shafts, which are connected to the two correction claws 141 in a one-to-one correspondence, and are used to drive the two correction claws 141 to rotate respectively. Of course, the driver may also have an output shaft, which is connected to the two correction claws 141 at the same time through a connecting member, and the connecting member may be arc-shaped, L-shaped, V-shaped, etc.

[0042] Specifically, in the exemplary embodiment, the auxiliary tooling for battery pack assembly also includes a position adjustment mechanism 150. The position adjustment mechanism 150 is installed on the top surface of the base 120 and is located as a whole on one side of the guide column 110. A correction seat 130 is installed on the position adjustment mechanism 150 so that the correction seat 130 can move close to or away from the guide column 110. The position adjustment mechanism 150 includes a first guide seat 151 and a second guide seat 152. The opposite ends of the first guide seat 151 are fixedly mounted on the top surface of the base 120 by legs respectively. The extension direction of the second guide seat 152 is perpendicular to the extension direction of the first guide seat 151, and can be slidably mounted on the top of the first guide seat 151 along the extension direction of the first guide seat 151. The correction seat 130 can be slidably mounted on the top of the second guide seat 152 along the extension direction of the second guide seat 152. Overall, it is convenient for the correction seat 130 to quickly move close to or away from the guide column 110.

[0043] It should be noted that, in some embodiments, slide grooves are respectively provided on the top surfaces of the first guide seat 151 and the second guide seat 152. Slide rails adapted to the slide grooves are respectively provided at the bottoms of the second guide seat 152 and the correction seat 130, so that the second guide seat 152 can slide along the extension direction of the first guide seat 151, and the correction seat 130 can slide along the extension direction of the second guide seat 152. In other embodiments, slide rails are respectively provided on the top surfaces of the first guide seat 151 and the second guide seat 152. Slide grooves adapted to the slide rails are respectively provided at the bottoms of the second guide seat 152 and the correction seat 130, so that the second guide seat 152 can slide along the extension direction of the first guide seat 151, and the correction seat 130 can slide along the extension direction of the second guide seat 152.

[0044] Specifically, in the exemplary embodiment, the auxiliary tooling for battery pack assembly also includes a positioning portion 160 and four running wheels. The positioning portion 160 is mounted on the top surface of the base 120 and is located between the first guide seat 151 and the guide column 110. A positioning groove 132 adapted to the positioning portion 160 is provided on the side of the correction seat 130 close to the guide column 110. When the correction seat 130 moves along the first guide seat 151 with the second guide seat 152 until the positioning groove 132 is aligned with the positioning portion 160, the correction seat 130 begins to move along the second guide seat 152 toward the guide column 110. During the movement of the correction seat 130 along the second guide seat 152 toward the guide column 110, the positioning portion 160 slides in the positioning groove 132. With the help of the positioning portion 160, precise positioning is achieved, the positioning efficiency is improved, and then the correction efficiency is improved, and the assembly efficiency is guaranteed. Four running wheels are respectively installed at the four corners of the bottom of the base 120 to facilitate the position transfer of the battery pack assembly auxiliary tooling.

[0045] Preferably, the positioning portion 160 includes a fixing seat 161 and a positioning pin 162. The fixing seat 161 is fixedly mounted on the top surface of the base 120. The positioning pin 162 is vertically arranged with its bottom end fixedly mounted on the top surface of the fixing seat 161.

[0046] The working process and principle of auxiliary tooling for battery pack assembly are as follows:

[0047] First, before the upper shell and the lower shell 300 of the battery pack are assembled, the two guide posts 110 are respectively installed on the poles 210 at both ends of the high-voltage connector 200. After that, the second guide seat 152 and the correction seat 130 slide along the first guide seat 151 in the direction close to the guide post 110. When the positioning groove 132 of the correction seat 130 is aligned with the positioning pin 162, the correction seat 130 begins to slide along the second guide seat 152 toward the guide post 110. When the inner wall of the correction groove 131 of the correction seat 130 contacts the side wall of the guide post 110, the two correction claws 141 rotate respectively so that the side walls of the two guide posts 110 are closely attached to the inner walls of the corresponding correction groove 131. Then, the upper shell is lowered with the help of the manipulator, so that the two guide posts 110 and the two poles 210 are inserted into the clearance holes on the upper shell in turn. Then, the two correction claws 141 rotate respectively to separate from the corresponding guide posts 110. Next, the correction seat 130 moves along the second guide seat 152 away from the guide post 110 . Then, the second guide seat 152 and the correction seat 130 slide along the first guide seat 151 in a direction away from the guide post 110 .

[0048] The utility model also provides a battery pack assembly device, including the auxiliary tooling for battery pack assembly provided by any of the above embodiments. Before the upper shell and the lower shell 300 of the battery pack are assembled, the auxiliary tooling for battery pack assembly replaces the human hand to correct the axial direction of the pole 210 of the high-voltage connector 200, so as to prevent the human hand from directly contacting the electrical device during assembly, avoid the human hand from being squeezed by the falling upper shell during the correction process, and improve the safety of the correction work. At the same time, it prevents the human hand from contacting the sealing glue pre-coated on the flange surface of the lower shell 300, which is conducive to reducing the risk of local sealing failure. Compared with the form of only using the guide column 110, it avoids the axial inclination of the guide column 110 with the pole 210, thereby avoiding the phenomenon that the axial inclination of the pole 210 affects the assembly efficiency. At the same time, it avoids the phenomenon that the axial inclination of the pole 210 damages the internal electrophoretic paint film of the upper shell, thereby ensuring the assembly efficiency, improving the safety of the assembly, and improving the yield of the assembled product.
