Description

Technical Field

[0001] This application relates to the field of liquid storage tank filling technology, and in particular to a liquid filling device. Background Technology

[0002] In the production of liquid storage tanks in the thermal management system of new energy vehicles, it is usually necessary to fill the liquid storage tanks with oil.

[0003] One type of oil injection device includes a machine platform, an oil injection mechanism, and a support mechanism. Both the oil injection mechanism and the support mechanism are mounted on the machine platform, with the support mechanism located below the oil injection mechanism. The oil injection mechanism is connected to an external oil source. During oil injection, the storage tank is placed on the support mechanism, and then the oil injection mechanism is activated to inject oil into the storage tank. Since the amount of oil injected into the storage tank is crucial to its proper functioning within the entire heat exchange system, the amount of oil injected into the storage tank needs to be measured at the end of the oil injection process. The weight of all components except the newly injected oil in the storage tank is known. The storage tank requires a specialized device to measure the oil injection volume, necessitating its handling before measurement, which causes operational inconvenience for workers. Utility Model Content

[0004] Therefore, it is necessary to provide a liquid injection device to address the above problems, which can facilitate workers in injecting liquid and measuring the injection volume.

[0005] The technical solution adopted in the embodiments of this application is as follows:

[0006] A liquid injection device for injecting liquid into a storage tank includes a machine platform, a liquid injection mechanism for performing liquid injection, and a support mechanism for placing a workpiece. The liquid injection device further includes a weighing component and a connecting component mounted on the support mechanism. The connecting component is at least partially connected to the weighing component and at least partially capable of being connected to or separated from the support mechanism. The support mechanism can be moved away from or placed on the machine platform by the action of the connecting component. The liquid injection mechanism is located on one side of the support mechanism. The liquid injection device has a first state and a second state. When the liquid injection device is in the first state, the connecting component is connected to the support mechanism, the support mechanism has a first distance in the vertical direction from the machine platform, and the weighing component weighs a first weight. When the liquid injection device is in the second state, the support mechanism has a second distance in the vertical direction from the machine platform, the connecting component is separated from the support mechanism, and the weighing component weighs a second weight. The first distance is not equal to the second distance.

[0007] By adopting the above technical solution, the injection mechanism is in working condition when in the second state. After the work is completed, the injection device enters the first state, at which point the weighing component displays the weight. By subtracting the known weight of the bearing mechanism, connecting parts, and the workpiece itself, the injection volume can be obtained. This integrates the weighing function with the injection function, making it convenient for workers to weigh the injection volume after injection. This injection device can be used for both injection and volume measurement, facilitating injection measurement for workers. Attached Figure Description

[0017] The following is combined with Figures 1-5 The specific embodiments are further described below.

[0018] This application discloses a liquid injection device, which can be applied to products that require the injection of liquid into their internal cavity.

[0019] As one implementation method, refer to Figure 1The device includes a machine platform 1, a liquid injection mechanism 2 for liquid injection, and a support mechanism 3 for placing workpieces. The liquid injection device also includes a weighing element 4 for displaying weight and a connecting element 5 mounted on the support mechanism 3. The connecting element 5 is at least partially connected to the weighing element 4 and at least partially connected to or separated from the support mechanism 3. The support mechanism 3 can be moved away from or placed on the machine platform 1 by the action of the connecting element 5. The liquid injection mechanism 2 is located on one side of the support mechanism 3. The liquid injection device has a first state and a second state. When the liquid injection device is in the first state, the connecting element 5 is connected to the support mechanism 3, the support mechanism 3 has a first distance from the machine platform 1 in the vertical direction, and the weighing element 4 weighs the first weight. When the liquid injection device is in the second state, the support mechanism 3 has a second distance from the machine platform 1 in the vertical direction, the connecting element 5 is separated from the support mechanism 3, and the weighing element 4 weighs the second weight. The first distance is not equal to the second distance. The first weight includes at least the weight of the support mechanism 3, the connecting element 5, and the workpiece after liquid injection. The second weight includes at least the weight of the connecting element 5.

[0020] By adopting the above technical solution, when in the second state, the liquid injection mechanism 2 is in working state. When the work is completed, the liquid injection device enters the first state. At this time, the weighing component 4 displays the weight. By subtracting the weight of the bearing mechanism 3, the connecting component 5 and the workpiece itself, the liquid injection volume can be obtained. The weighing function and the liquid injection function are integrated, which makes it convenient for the staff to weigh the liquid injection volume after the liquid injection is completed.

[0021] As one specific implementation method, refer to Figure 4 The connecting member 5 includes a first power member 6. The body of the first power member 6 is fixed to the weighing member 4. The driving part of the first power member 6 can be connected to or separated from the bearing mechanism 3. When in the first state, the driving part of the first power member 6 is connected to the bearing mechanism 3. When in the second state, the driving part of the first power member 6 is separated from the bearing mechanism 3. The first distance is less than the second distance. When weighing, the driving part of the first power member 6 is connected to the bearing mechanism 3. Then, the first power member 6 is started to drive the bearing mechanism 3 to rise and detach from the machine platform 1. The system is automated, convenient and fast.

[0022] Furthermore, refer to Figure 4The connecting component 5 includes a mounting frame 7 and a gripper cylinder 8. The weighing component 4 is fixed to the mounting frame 7 and is located above the bearing mechanism 3. The gripper cylinder 8 is fixed to the driving part of the first power component 6, and the body part of the first power component 6 is fixed to the weighing component 4. The first power component 6 can drive the gripper cylinder 8 to move closer to or away from the bearing mechanism 3. The bearing mechanism 3 has a locking interface 10, and the gripper part of the gripper cylinder 8 is provided with a locking block 9. When in the first state, the bearing mechanism 3 is located between the grippers of the gripper cylinder 8. The locking block 9 is driven by the gripper cylinder 8 to engage with the locking interface 10. After the liquid injection work is completed, the first power component 6 drives the gripper cylinder 8 to move closer to the bearing mechanism 3, so that the bearing mechanism 3 is located between the grippers of the gripper cylinder 8. Then, the gripper cylinder 8 is activated to drive the locking block 9 to engage with the locking interface 10, and then the first power component 6 is driven to raise the bearing mechanism 3 for weighing. The system is automated, efficient and convenient.

[0023] As another embodiment, refer to Figure 1 , Figure 2 and Figure 3 The connecting component 5 includes a first power component 6. The body of the first power component 6 is fixed to the weighing component 4. The driving part of the first power component 6 can be connected to or separated from the bearing mechanism 3. When in the first state, the driving part of the first power component 6 is connected to the bearing mechanism 3. When in the second state, the driving part of the first power component 6 is separated from the bearing mechanism 3. The first distance is greater than the second distance. Compared with lifting, the weighing component 4 can be directly fixed to the machine base 1, without the need to set up a separate installation component for the weighing component 4, thus reducing costs.

[0024] Furthermore, refer to Figure 1 , Figure 2 and Figure 3 The machine base 1 is equipped with a second power component 12 and a moving plate 11. The body of the second power component 12 is fixed to the machine base 1. The moving plate 11 is at least partially connected to the drive part of the second power component 12. The second power component 12 can drive the moving plate 11 to move horizontally. The bearing mechanism 3 is located on the moving plate 11, and the weighing component 4 is located on the moving path of the moving plate 11. When in the first state, the moving plate 11 drives the bearing mechanism 3 to move directly above the weighing component 4. When in the second state, the moving plate 11 drives the bearing mechanism 3 to move below the liquid injection mechanism 2. When liquid injection is performed, the second power component 12 is activated, causing the moving plate 11 to drive the bearing mechanism 3 to move below the liquid injection mechanism 2. After the liquid injection is completed, the moving plate 11 drives the bearing mechanism 3 to move above the weighing component 4. Then, the first power component 6 is activated to lift the bearing mechanism 3, reducing the probability of interference between the bearing mechanism 3 and the liquid injection mechanism 2 during weighing.

[0025] Furthermore, refer to Figure 1 , Figure 2and Figure 3 The weighing component 4 is fixed to the machine base 1. The connecting component 5 includes an abutment plate 13, which is fixed to the driving part of the first power component 6. The abutment plate 13 moves vertically under the action of the first power component 6. The moving plate 11 has an opening 14. The projected area of ​​the abutment plate 13 in the vertical direction is equal to the area of ​​the opening 14. When in the first state, the abutment plate 13 is at least partially in contact with the bearing mechanism 3. When in the second state, the abutment plate 13 disengages from the bearing mechanism 3, and the abutment plate 14 disengages from the opening 13. Furthermore, it is misaligned with the opening 14. During weighing, the opening 14 is directly opposite the abutment plate 13, and the abutment plate 13 can pass through. This indicates that the bearing mechanism 3 has moved to the weighing position. When the bearing mechanism 3 has not moved to the weighing position, the abutment plate 13 will be blocked by the moving plate 11 when it rises, reminding the staff that the device is not fully in place. This reduces the probability that the abutment plate 13 will lift the bearing mechanism 3 when the bearing mechanism 3 has not moved to the weighing position, thus causing the bearing mechanism 3 to deviate and resulting in inaccurate weighing.

[0026] Furthermore, refer to Figure 1 , Figure 2 and Figure 3 The movable plate 11 is vertically provided with a support column 15. The bearing mechanism 3 includes a bearing frame 301 and a mounting plate 304. When in the first state, the support column 15 and the mounting plate 304 are not in contact. When in the second state, the end of the support column 15 away from the movable plate 11 abuts against the mounting plate 304. The bearing mechanism 3 makes point contact with the support column 15 through the mounting plate 304. Compared with surface contact with the movable plate 11, it is more labor-saving when lifting.

[0027] Furthermore, refer to Figure 1 , Figure 2 and Figure 3 The mounting plate 304 has mounting holes, and the support column 15 is conical. The maximum diameter of the support column 15 is greater than the diameter of the mounting hole, and the minimum diameter of the support column 15 is less than the diameter of the guide hole 16. In the first state, the outer wall of the support part does not contact the inner wall of the guide hole 16, and the small diameter part of the support column 15 is located inside the guide hole 16. In the second state, the outer wall of the support column 15 abuts against the inner wall of the guide hole 16. When the bearing mechanism 3 is lifted, although the support column 15 does not contact the inner wall of the guide hole 16, it is still inside the guide hole 16. At this time, when the bearing mechanism 3 is affected by external factors and shifts, the support column 15 can limit the mounting plate 304 through the side wall. At the same time, when the weighing operation is in normal operation, the support rod does not contact the guide hole 16, reducing the probability of external contact affecting the accuracy of weighing.

[0028] As one implementation method, refer to Figure 1 , Figure 2 and Figure 3The supporting mechanism 3 includes a supporting frame 301, a placement plate 302 for placing workpieces, and a third power component 303. The placement plate 302 is rotatably connected to the supporting frame 301. The body of the third power component 303 is fixedly connected to the supporting frame 301. The driving part of the third power component 303 is fixedly connected to the placement plate 302. The third power component 303 can drive the placement plate 302 to rotate at any angle. When the injection port positions of different workpieces are different, rotating the placement plate 302 makes it easier to find the injection position, thereby expanding the applicability of the device.

[0029] As one implementation method, refer to Figure 5 The liquid injection device includes a fourth power component 17, the body of which is fixed to the machine base 1. The liquid injection mechanism 2 is fixed to the drive part of the fourth power component 17. There are at least two bearing mechanisms 3. The fourth power component 17 can drive the liquid injection mechanism 2 to move above any one of the bearing mechanisms 3. The liquid injection device has a working state. When it is in the working state, the liquid injection mechanism 2 is located above the bearing mechanism 3 in the second state. When one of the bearing mechanisms 3 is weighing, the fourth power component 17 drives the liquid injection mechanism 2 to move above other bearing mechanisms 3 to inject liquid into other workpieces, reducing the standby time of the entire device during the weighing process.

[0030] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications without departing from the concept of the present invention, and these modifications all fall within the protection scope of the present invention.
