Description

Technical Field

[0001] This utility model relates to the technical field of power battery production equipment, specifically to a spraying mechanism for insulating coating of power batteries. Background Technology

[0002] In the production process of power batteries, in order to ensure the safety and performance of the batteries, it is necessary to spray an insulating coating on the battery casing or specific components to prevent problems such as short circuits and leakage. Uneven spraying can lead to unstable insulation performance, affecting the quality and safety of the batteries. Low spraying efficiency increases production costs and production cycle. Therefore, it is particularly important to develop a spraying mechanism for insulating coatings of power batteries.

[0003] A battery coating apparatus, reference publication number CN218423563U, includes: a coating mechanism comprising a coating component and a receiving component, the coating mechanism being used to coat a battery with a protective material; the receiving component being used to hold the battery, and a protective layer being provided on the surface of the receiving component, the protective layer being incompatible with the protective material; and a blowing mechanism located on one side of the coating mechanism, used to blow away and remove the protective material adhering to the surface of the protective layer. This battery coating apparatus utilizes the incompatibility between the protective layer and the protective material by providing a protective layer on the surface of the receiving component of the coating mechanism. The blending properties allow the blowing mechanism to quickly and effectively remove protective materials adhering to the surface of the housing components, ensuring the cleanliness of the battery coating device surface and reducing cleaning costs. At the same time, since the protective material can be removed by blowing, the service life of the battery coating device can be extended. As can be seen from the above, although this device can be used well, it is usually not convenient to carry out battery coating operations in a closed environment. This makes the battery coating process susceptible to interference from external airflow, which affects the coating effect and often troubles users. Utility Model Content

[0008] Preferably, the top of the first support frame is provided with a limiting rail, and the top of the limiting rail is slidably connected to the bottom of the movable plate. The limiting rail is provided to limit the movement range of the movable plate.

[0009] Preferably, the top of the movable plate is provided with a second lead screw transmission mechanism, a second motor is installed on the outer wall of one side of the second lead screw transmission mechanism, the input end of the second motor is electrically connected to the output end of the microcontroller inside the control panel, a component holder is movably installed on the top of the second lead screw transmission mechanism, and a spray head is installed on the inner wall of the component holder.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the spraying mechanism for the insulating coating of the power battery not only ensures the spraying effect of the power battery when the spraying mechanism is used, but also improves the spraying accuracy of the power battery and improves the convenience of using the spraying mechanism.

[0012] (1) By starting the electric push rod to extend and retract, the electric push rod drives the box door to rotate at the top of the chassis. When the box door rotates downward, the bottom of the box door contacts the top of the lower baffle to block and close the opening area on the surface of the chassis, so that the battery can be sealed inside the chassis for spraying, effectively blocking the external airflow from interfering with the battery spraying, thus ensuring the spraying effect of the power battery when the spraying mechanism is used.

[0013] (2) The first motor drives the first lead screw transmission mechanism to operate, so that the first lead screw transmission mechanism drives the movable plate to slide at the top of the limit rail, thereby adjusting the position of the spray head back and forth. Then, the second motor drives the second lead screw transmission mechanism to operate, so that the second lead screw transmission mechanism drives the placement frame to move laterally, thereby adjusting the position of the spray head left and right. In this way, the spray head can be moved above the designated area of ​​the power battery, so that the designated area of ​​the power battery can be easily sprayed, thereby improving the spraying accuracy of the spraying mechanism on the power battery.

[0014] (3) With the storage cabinet, when the cabinet door is opened, the items can be stored in the storage cabinet. Because the surface of the cabinet door is equipped with a transparent observation window, the spraying status of the power battery inside the chassis can be viewed through the transparent observation window, thereby improving the convenience of using the spraying mechanism.

[0025] The top of the first support frame 12 is provided with a limiting rail 13, and the top of the limiting rail 13 is slidably connected to the bottom of the movable plate 17.

[0026] In use, the movement range of the movable plate 17 is limited by the setting of the limit rail 13;

[0027] The top of the movable plate 17 is provided with a second lead screw transmission mechanism 18. A second motor 19 is installed on the outer wall of one side of the second lead screw transmission mechanism 18. The input end of the second motor 19 is electrically connected to the output end of the microcontroller inside the control panel 8. A component holder 20 is movably installed on the top of the second lead screw transmission mechanism 18. A spray head 21 is installed on the inner wall of the component holder 20.

[0028] When in use, the spray head 21 is set up to perform spraying operations on the power battery;

[0029] A liquid storage tank 22 is installed on one side of the top of the substrate 11. A positioning frame 23 is installed on the top of the substrate 11 on one side of the liquid storage tank 22. An infusion pump 24 is installed on the top of the positioning frame 23. The input end of the infusion pump 24 is electrically connected to the output end of the microcontroller inside the control panel 8. One end of the infusion pump 24 is connected to the outer wall of the liquid storage tank 22 through a conduit. The other end of the infusion pump 24 is connected to the top of the spray head 21 through a conduit.

[0030] In use, the infusion pump 24 is used to deliver the paint liquid inside the storage tank 22 to the inside of the spray head 21.

[0031] A lower baffle 4 is installed at the lower end of the surface of the chassis 3. A door 5 is rotatably installed on the surface of the chassis 3 above the lower baffle 4. A transparent observation window 6 is provided on the surface of the door 5. Electric push rods 7 are rotatably installed on the inner walls on both sides of the door 5. The end of the electric push rod 7 away from the door 5 is rotatably connected to the inner wall of the chassis 3.

[0032] In this embodiment, the power battery is first placed on the top of the spraying station 9.

This allows the spray head 21 to be moved above the designated area of ​​the power battery for spraying. Finally, through the setting of the storage cabinet 10, when the cabinet door 2 is opened, the items can be stored in the storage cabinet 10. Because the surface of the cabinet door 5 is provided with a transparent observation window 6, the spraying status of the power battery inside the chassis 3 can be viewed through the transparent observation window 6. Furthermore, both the first lead screw transmission mechanism 15 and the second lead screw transmission mechanism 18 are composed of components such as a housing, lead screw, and nut pair. Specifically, the drive component drives the lead screw to rotate, and the nut pair slides on the outer wall of the lead screw to drive the movable plate 17 and the component holder 20 to move in translation. This technology belongs to the prior art, so its detailed structure will not be described or shown, thus completing the use of the spraying mechanism.
