Technical Field

[0002] The thermal management module is a component in new energy vehicles that regulates the overall vehicle temperature. A typical thermal management module includes a base and a temperature sensor. The temperature sensor is partially inserted into a mounting sleeve of the base and secured to the sleeve using a U-shaped clamp. Currently, one method for installing the temperature sensor involves: first, an assembly fixture moves the temperature sensor to a position directly above the mounting sleeve, then controls the sensor to move downwards to partially insert it into the sleeve; subsequently, another assembly fixture moves the U-shaped clamp to a horizontal position near the mounting sleeve, and then clamps the U-shaped clamp onto the sleeve.

When the assembly fixture is used to assemble the thermal management module, the first direction is vertical. The working process is as follows: First, at the loading station, the temperature sensor is held in the first holding position using the first holding member, and the U-shaped clamp is held in the second holding position using the second holding member. Then, the assembly fixture carrying the U-shaped clamp and the temperature sensor is transferred to the assembly station carrying the base of the thermal management module, so that the target position is located on the mounting sleeve of the base.

[0037] The purpose of this invention is to provide an assembly fixture that can be used to quickly assemble a temperature sensor onto the base of a thermal management module in a new energy vehicle or other equipment.

[0038] To make the objectives, advantages, and features of this utility model clearer, the following detailed description is provided in conjunction with the accompanying drawings. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to conveniently and clearly illustrate the objectives of the embodiments of this utility model. The same or similar reference numerals in the drawings represent the same or similar parts.

[0039] Figure 1 and Figure 2 The diagram shows structural schematics of the assembly tooling provided in some embodiments of this utility model in different orientations. Figure 3 This is a sectional view of the assembly fixture. For example... Figures 1 to 3As shown, the assembly fixture includes a base 100, a first assembly mechanism 200, and a second assembly mechanism 300. Both the first assembly mechanism 200 and the second assembly mechanism 300 are disposed on the base 100. The first assembly mechanism 200 includes a first retainer 210 and a first drive member 220, and the second assembly mechanism 300 includes a second retainer 310 and a second drive member 320. The first retainer 210 defines a first retaining position (not shown in the figure) on the base 100, and the second retainer 220 defines a second retaining position (not shown in the figure) on the base 100. The first drive member 220 has a free end, which is configured to move along a first direction to approach or move away from a target position (not shown in the figure), and the free end of the first drive member 220 can pass through the first retaining position during movement along the first direction. The second driving member 320 has a free end, which is configured to move along a second direction to approach or move away from the target position, and the free end of the second driving member 320 can pass through a second holding position during its movement along the second direction. The target position is the intersection of the straight line containing the movement path of the free end of the first driving member 210 and the straight line containing the movement path of the free end of the second driving member 320.

[0040] The assembly fixture can be used to assemble the thermal management module on new energy vehicles, shorten the assembly time of the thermal management module, and improve production efficiency.

[0041] like Figures 5 to 7 As shown, the thermal management module includes a base 10, a temperature sensor 20, and a U-shaped clamp 30. A mounting sleeve 11 is provided on the base 10, with one axial end of the mounting sleeve 11 being an open end. The temperature sensor 20 is partially inserted into the mounting sleeve 11, and the U-shaped clamp 30 is used to engage with the outside of the mounting sleeve 11, applying a radially inward compressive force to the mounting sleeve 11, so that the mounting sleeve 11 and the temperature sensor 20 remain relatively stationary under the compressive force. It can be understood that the temperature sensor 20 includes a main body 21 and a connector 22, with the connector 22 connected to one end of the main body 21. Furthermore, the temperature sensor 20 has a first designated portion, and the mounting sleeve 11 has a second designated portion. When the temperature sensor 20 is partially inserted into the mounting sleeve 11, and the first designated portion and the second designated portion are aligned vertically, it indicates that the temperature sensor 20 is properly installed.

[0042] In actual operation, the mounting sleeve 11 extends vertically, and the upper end of the mounting sleeve 11 is an open end. Correspondingly, the first direction is vertical, and the first holding position is located directly above the target position.

[0043] The process of assembling the thermal management module using the assembly fixture is as follows:

[0044] First, at the loading station, the temperature sensor 20 is positioned in the first holding position using the first holding member 210, and the main body 21 of the temperature sensor 20 extends along the second direction, with the main body 21 located below the connector 22 and closer to the target position than the connector 22; and the U-shaped clamp 30 is positioned in the second holding position using the second holding member 310, with the opening of the U-shaped positioning clamp 30 facing the target position.

[0045] Then, the assembly fixture carrying the U-shaped clip 30 and the temperature sensor 20 is transferred to the assembly station carrying the base 10, with the first direction extending vertically and the target position located on the mounting sleeve 11. At this time, the main body 21 of the temperature sensor 20 partially passes through the mounting sleeve 11, and the first designated portion on the temperature sensor 20 is located above the second designated portion of the mounting sleeve 11.

[0046] Next, the free end of the first driving member 220 is controlled to move vertically downward, and the temperature sensor 20 is pushed to move vertically downward until the first designated point on the temperature sensor 20 is aligned vertically with the second designated point on the mounting sleeve 11, so that the temperature sensor 20 is installed in place.

[0047] Next, the free end of the second drive member 320 is controlled to move along the second direction toward the target position, so as to push the U-shaped clip 30 along the second holding position toward the target position, until the U-shaped clip 30 is engaged on the mounting sleeve 11.

[0048] In the above process, the assembly fixture completes the transfer of the U-shaped clamp 30 and the temperature sensor 20 in one go, thereby shortening the total transfer time of the materials (i.e., the U-shaped clamp 30 and the temperature sensor 20), thus shortening the assembly time of the thermal management module and improving production efficiency. Furthermore, preferably, the first direction is perpendicular to the second direction; in the illustration, the first direction is identified by a double-headed arrow Z, and the second direction by a double-headed arrow X.

[0049] Optionally, the assembly fixture further includes a first adapter 400, which is connected to the base 100. The assembly fixture can be connected to a robotic arm (not shown) via the first adapter 400. Further, the first drive member 220 includes any suitable first drive unit that can operate automatically under the control of a power source, and the second drive member 320 includes any suitable second drive unit that can operate automatically under the control of a power source. For example, both the first and second drive units are cylinders. The free end of the first drive member 220 is the free end of the piston rod of the cylinder serving as the first drive unit, or other components connected to the free end of the piston rod of the cylinder, such as the push rod 223 described later. The free end of the second drive member 320 is the free end of the piston rod of the cylinder serving as the second drive unit, or other components connected to the free end of the piston rod of the cylinder, such as the push cylinder 333 described later. Therefore, the robotic arm can move the assembly fixture from the material loading station to the assembly station. Furthermore, the first drive unit controls the movement of the free end of the first drive component 220, and the second drive unit controls the movement of the free end of the second drive component 320, achieving automated and intelligent assembly, further improving assembly efficiency, and reducing labor costs. It can be understood that when the first and second drive units are cylinders, the power source is an air source.

[0050] Preferably, the assembly fixture is detachably connected to the robotic arm. This is because one type of assembly fixture is suitable for several types of temperature sensors 20 and corresponding U-shaped clamps 30. When the specifications of the temperature sensor 20 to be assembled and the U-shaped clamp 30 do not match the specifications of the assembly fixture currently mounted on the robotic arm, an assembly fixture matching the temperature sensor 20 and U-shaped clamp 30 of the thermal management module to be assembled can be replaced.

[0051] Preferably, the robotic arm includes a robotic arm body and a second adapter portion disposed at the end of the robotic arm body, wherein the second adapter portion is a robot-side module in a robot quick-change unit, and the first adapter portion is a tool-side module in the robot quick-change unit. This shortens the assembly and disassembly time of the assembly fixture and enables rapid switching between assembly fixtures of different specifications.

[0052] The structure of the assembly fixture will be further described below. It should be noted that the following description is only of one optional structure of the assembly fixture, and is not the only structure of the assembly fixture, and should not be construed as an undue limitation on this utility model.

[0053] Please refer to Figures 2 to 3The base 100 has an inner cavity 110, which includes a first sub-cavity 111 and a second sub-cavity 112. The first sub-cavity 111 extends along the first direction, and the second sub-cavity 112 extends along the second direction, and the first sub-cavity 111 and the second sub-cavity 112 intersect at the target position. The first holding position is located within the first sub-cavity 111, and the second holding position is located within the second sub-cavity 112.

[0054] The movement of the free end of the first driving member 220 along the first direction means that the free end of the first driving member 220 moves within the first sub-cavity 111 along the extension direction of the first sub-cavity 111, so that the free end of the first driving member 220 can pass through the first holding position during the movement; similarly, the movement of the free end of the second driving member 320 along the second direction means that the free end of the second driving member 320 moves within the second sub-cavity 112 along the extension direction of the second sub-cavity 112, so that the free end of the second driving member 320 can pass through the second holding position during the movement.

[0055] The base 100 also has an opening communicating with the inner cavity 110, which can be referred to as the first opening 101. Viewed in the first direction, the first opening 101 is located on the side of the target position away from the first holding position; the first opening 101 also extends along the second direction, and in the second direction, the first opening 101 extends at least from the target position to the second holding position. Thus, in actual operation, the first opening 101 is located at the bottom of the base 100. The advantage of this arrangement is that, at the loading station, by controlling the assembly fixture located directly above the loading station to move vertically downwards, the temperature sensor 20 can enter the first sub-cavity 111 from the first opening 101 and reach the first holding position, and the U-shaped clamp 30 can enter the second sub-cavity 112 from the first opening 101 and reach the second holding position.

[0056] Optionally, the first retainer 310 includes a spring sheet extending along the first direction, with one end of the spring sheet connected to the cavity wall of the first sub-cavity 111 and the other end being a free end. The free end of the spring sheet can move in a direction away from the axis of the first sub-cavity 111 under the action of an external force acting radially outward along the first sub-cavity 111, thereby storing elastic potential energy.

[0057] The first holding position refers to the position of the first sub-cavity 111 corresponding to the spring piece. During the application of the assembly fixture, the "radial outward external force along the first sub-cavity 111" originates from the temperature sensor 20. Thus, the spring piece can apply a radial inward compressive force along the first sub-cavity 111 to the temperature sensor 20 under the action of elastic potential energy, and clamp the temperature sensor 20 together with the cavity wall of the first sub-cavity 111 to position and hold the temperature sensor 20 in the first holding position.

[0058] It is understood that when the free end of the first driving member 220 moves in a direction close to the target position and passes through the first holding position, the first driving member 220 applies a pushing force to the temperature sensor 20 in a direction from the second holding position to the target position, and overcomes the squeezing force applied to the temperature sensor 20 by the spring, so that the temperature sensor 20 moves in a direction from the first holding position to the target position.

[0059] Optionally, the base 100 is further provided with a second opening 102 communicating with the inner cavity 110. The second opening 102 is specifically provided on the cavity wall of the first sub-cavity 111 and corresponds to the position of the spring piece, so as to provide movement space for the spring piece when the free end of the spring piece moves along the axis away from the first sub-cavity 111.

[0060] Optionally, the first driving member 220 includes a fixed part, a movable part, and a pusher cylinder 223. For ease of distinction, the fixed part of the first driving member 220 is referred to as the first fixed part 221, and the movable part as the first movable part 222. The first fixed part 221 is fixed to the base 100 and may be located on the side of the first retainer 210 away from the target position in the first direction (i.e., on the upper side of the first retainer 210). The first movable part 222 is connected to the first fixed part 221 and is capable of extending and retracting relative to the first fixed part 221 in the first direction. The first movable part 222 and the first fixed part 221 constitute at least a part of the aforementioned first driving member. The pusher cylinder 223 is connected to the first movable part 222, preferably connected to the end of the first movable part 222 away from the first fixed part 221. The push cylinder 223 extends along the first direction, forming the free end of the first drive member 220, and moves along the first direction as the first movable part 222 extends and retracts. Specifically, when the first movable part 222 extends, the push cylinder 223 moves along the first direction toward the target position, and when the first movable part 222 retracts, the push cylinder 223 moves along the first direction away from the target position.

[0061] like Figure 4 As shown, the pusher cylinder 223 includes a side wall 2231, a top wall 2232, and a connecting post 2233. The top wall 2232 is connected to the end of the side wall 2231 away from the target position. The connecting post 2233 is connected to the top wall 2232 and is also connected to the first movable part 222.

[0062] Please refer to Figure 6 In some embodiments, the terminal 22 of the temperature sensor 20 protrudes radially outward from the body portion 21. Correspondingly, as... Figure 4 As shown, a clearance notch 2234 is provided on the side wall of the push cylinder 223, extending from one end of the side wall of the push cylinder 223 to the other end along the first direction. The push cylinder 223 and the first movable part 222 remain relatively stationary in the circumferential direction of the push cylinder 223, so that the orientation of the clearance notch 2234 remains fixed. It can be understood that when the temperature sensor 20 enters the first sub-cavity 111, the connector 22 should be aligned with the clearance notch 2234 in the circumferential direction of the push cylinder 223.

[0063] This embodiment of the invention does not particularly limit the connection method between the first movable part 222 and the connecting post, as long as it enables the pusher cylinder 223 to move along the first direction as the first movable part 222 extends and retracts, and keeps the pusher cylinder 223 and the first movable part 222 circumferentially stationary. For example, when the first driving part is a cylinder, the first fixed part 221 is the cylinder body, the first movable part 222 is the piston rod, and the outer circumferential surface of the piston rod away from the cylinder body is provided with threads. At least a portion of the outer circumferential surface of the connecting post 2233 is provided with threads. The first driving member 210 also includes a connecting sleeve 224, the inner circumferential surface of which is provided with threads. A portion of the connecting sleeve 224 is sleeved on the piston rod, and another portion is sleeved on the connecting post, and the connecting sleeve 224 is threadedly connected to the piston rod and the connecting post.

[0064] like Figure 3 and Figure 6 As shown, a stepped surface 23 is formed on the main body 21 of the temperature sensor 20, facing the connector 22. When the pusher cylinder 223 moves in a direction close to the target position, the end (i.e., the lower end) of the side wall of the pusher cylinder 223 near the target position can abut against the stepped surface 23 and apply a pushing force to the temperature sensor 20.

[0065] Additionally, the base 100 may also be provided with a third opening 103 communicating with the inner cavity 110. The third opening is specifically located on the cavity wall of the first sub-cavity 111 and extends along the first direction. The third opening 103 is aligned circumferentially with the clearance notch 2234 on the pusher cylinder 223, allowing the wiring head 22 of the temperature sensor 20 to partially pass through the third opening 103, thereby reducing the inner diameter of the first sub-cavity 111 and thus reducing the volume of the base 100. Optionally, the third opening 103 is located on the side of the cavity wall of the first sub-cavity 111 near the second holding position.

[0066] Optionally, the U-shaped clip 30 may be made of a ferromagnetic material. In this regard, the second retaining member 310 preferably includes a magnetic body, which may be disposed within or outside the second sub-cavity 112, provided that the magnetic field of the magnetic body is at least partially located within the first sub-cavity 111. The second retaining position is located within the magnetic field range of the magnetic body. Thus, when the U-shaped clip 30 reaches the second retaining position, it can be attracted by the magnetic body and positioned and held in the second retaining position.

[0067] It can be understood that when the free end of the second driving member 320 moves in a direction close to the target position and passes through the second holding position, the second driving member 320 applies a pushing force to the U-shaped clip 30 in a direction from the second holding position to the target position, and overcomes the magnetic force applied to the U-shaped clip 30 by the magnetic body, so that the U-shaped clip 30 moves in a direction from the second holding position to the target position.

[0068] Optionally, the second driving member 320 includes a fixed portion, a movable portion, and a push rod 323. The fixed portion of the second driving member 320 is referred to as the second fixed portion 321, and the movable portion is referred to as the second movable portion 322. The second movable portion 322 is connected to the second fixed portion 321 and is capable of extending and retracting relative to the second fixed portion 321 in the second direction. The second fixed portion 321 and the second movable portion 322 constitute at least a part of the aforementioned second driving member.

When the second movable part 322 retracts, the push rod 323 moves along the second direction away from the target position.

[0069] In some embodiments, the first adapter 400 is directly connected to the base 100; in other embodiments, the first adapter 400 is indirectly connected to the base 100 through other mechanisms.

[0070] In a preferred embodiment, please refer to [link / reference needed]. Figures 1 to 3 The assembly fixture further includes a floating mechanism 500, which is disposed on the end of the base 100 away from the first opening. The first adapter 400 is connected to the base 100 via the floating mechanism 500.

[0071] The floating mechanism 500 includes a guide shaft 510, a transition block 520, and an elastic element 530. The guide shaft 510 extends along the first direction, and one end of the guide shaft 510 is connected to the end of the base 100 away from the first opening. The transition block 520 has a guide hole 521 extending along the first direction. The transition block 520 is sleeved on the guide shaft 520 through the guide hole 521 and can move along the guide shaft 520. The elastic element 530 is disposed between the base 100 and the transition block 520. The first transition portion 400 is connected to the transition block 520, for example, connected to the side of the transition block 520 away from the base 100.

[0072] In this embodiment of the present invention, the maximum dimension of the assembly fixture in the first direction is equal to the distance between the end of the first adapter 400 away from the base 100 and the end of the base 100 away from the first adapter 400. By providing the floating mechanism 500, the maximum dimension of the assembly fixture in the first direction is adjustable, thereby enabling the assembly fixture to adapt to the base 10 of different thermal management modules. It is understood that when the first adapter 400 is subjected to a force in the direction of the first adapter 400 pointing towards the base 100, the first adapter 400 moves towards the base 100 along the first direction to reduce the maximum size of the assembly tool in the first direction. At the same time, the elastic member 530 is compressed to store elastic potential energy. When the force in the direction of the first adapter 400 pointing towards the base 100 is reduced or canceled, the elastic member 530 releases the elastic potential energy and drives the first adapter 400 to move away from the base 100 along the first direction, thereby increasing the maximum size of the assembly tool in the first direction.

[0073] Optionally, the guide shaft 510 includes a guide post 511, a guide sleeve 512, and a limiting piece 513. The guide post 511 extends along the first direction, and one end of the guide post 511 is connected to the end of the base 100 away from the first opening. The guide post 511 also partially passes through the guide hole 521. The guide sleeve 512 has a hollow structure, and one end of the guide sleeve 512 is connected to the transition block 520. The guide sleeve 512 is also fitted onto a portion of the outer circumferential surface of the guide post 511. The limiting piece 513 is connected to the end of the guide post 511 away from the base 100, and the outer diameter of the limiting piece 513 is larger than the inner diameter of the guide sleeve 512 and smaller than or equal to the diameter of the guide hole 521. Under the action of the limiting piece 513, the guide post 511 can be prevented from disengaging from the guide sleeve 512.

[0074] Preferably, there are multiple guide shafts 510, such as two. The multiple guide shafts 510 are arranged at equal intervals around an axis. More preferably, the elastic element 530 is a spring, and even more preferably, the number of elastic elements 530 is not less than the number of guide shafts 510, and one elastic element 530 is fitted around the outer periphery of each guide shaft 510.

[0075] This utility model embodiment also provides an assembly system, including a robotic arm and an assembly fixture as described above, wherein the assembly fixture is connected to the robotic arm, and preferably the two are detachably connected.

[0076] While the present invention has been disclosed above, it is not limited thereto. Those skilled in the art can make various modifications and variations to the present invention without departing from its spirit and scope. Therefore, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention also intends to include such modifications and variations.
