Description

Technical Field

[0001] This utility model relates to the field of adhesive coating device technology, and in particular to a closed-loop mechanism for ceramic adhesive coating of lithium batteries. Background Technology

[0002] During the production of lithium batteries, an adhesive coating process is required to coat the edges of the coated electrode sheets using an adhesive coating device. However, existing adhesive coating devices cannot adjust the position of the dispensing pump in real time according to the width of the substrate gaps in the substrate components, thus failing to achieve quantitative adjustment. When the substrate gaps change, the unadjustable dispensing pump makes it difficult for the adhesive to fit the substrate gaps, reducing the coating effect. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies that cannot adjust the position of the dispensing pump in real time according to the width of the gap in the substrate, and to propose a closed-loop mechanism for coating ceramics in lithium batteries.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] Design a closed-loop mechanism for ceramic coating of lithium batteries, including a second support section, and further comprising:

[0006] The quantitative dispensing assembly includes multiple sets, which are installed at the free end of the second support portion. Each quantitative dispensing assembly includes a fixed frame for fixing to the free end of the second support portion. A first sliding frame is longitudinally slidably connected to one outer end of the fixed frame, and a first adjusting motor is driven between the first sliding frame and the fixed frame. A second sliding frame is laterally slidably connected to one outer end of the first sliding frame, and a second adjusting motor is driven between the second sliding frame and the first sliding frame. A dispensing pump is bolted to one outer end of the second sliding frame.

[0007] Preferably, the second support portion includes a support frame, a lifting cylinder is bolted to one side of the support frame, a lifting frame is fixedly mounted on the output shaft of the lifting cylinder, a slide rail is fixedly mounted on one side of the lifting frame, a fixing groove is provided on the outer end face of the slide rail, and the fixing frame is connected to the fixing groove by bolts.

[0008] Preferably, the first sliding frame is slidably connected to the slide rail.

[0009] Preferably, the outer wall of the support frame is provided with an adjustment groove, which is an arc-shaped structure. The lifting cylinder is fixed to the support frame by two sets of bolts, one of which is fixedly installed inside the adjustment groove.

[0010] Preferably, it also includes a first support portion, the free end of which is equipped with a CCD camera.

[0011] Preferably, the side where the first support portion is located is the input side.

[0012] Preferably, a distance sensor is bolted to one end of the outer side of the second sliding frame, and the distance sensor is located on one side of the dispensing pump.

[0013] The beneficial effects of the closed-loop ceramic coating mechanism for lithium batteries proposed in this utility model are as follows:

[0014] The first adjusting motor can drive the fixed frame and the first sliding frame to adjust their longitudinal position. The second adjusting motor can drive the first sliding frame and the second sliding frame to adjust their lateral position. The longitudinal and lateral adjustments can change the position of the dispensing pump, thereby achieving quantitative adjustment.

[0015] The CCD camera and range sensor are configured to monitor the position and height of the substrate gap in real time, thereby assisting the first and second adjustment motors in adjustment. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example 1

[0023] Reference Figure 1 , Figure 3 , Figure 4 A closed-loop mechanism for ceramic coating of lithium batteries includes a second support section X3, and further includes:

[0024] The quantitative dispensing assembly includes multiple sets, which are installed on the free end of the second support part X3. Each quantitative dispensing assembly includes a fixing frame 9 for fixing to the free end of the second support part X3. A first sliding frame 10 is longitudinally slidably connected to one outer end of the fixing frame 9. A first adjusting motor 11 is driven between the first sliding frame 10 and the fixing frame 9. A second sliding frame 12 is laterally slidably connected to one outer end of the first sliding frame 10. A second adjusting motor 13 is driven between the second sliding frame 12 and the first sliding frame 10. A dispensing pump 14 is bolted to one outer end of the second sliding frame 12.

[0025] Furthermore, refer to Figure 1 It also includes a first support part 1, and a CCD camera 2 is mounted on the free end of the first support part 1;

[0026] Furthermore, the side where the first support section 1 is located is the input side;

[0027] Furthermore, refer to Figure 4 A distance sensor 15 is bolted to one side of the second sliding frame 12. The distance sensor 15 is located on one side of the dispensing pump 14.

[0028] Working principle:

[0029] Reference Figure 1 The substrate X1 is first scanned by the CCD camera 2 installed in the first support part 1. The state of the substrate gap X2 on the substrate X1 is determined by image recognition, and the state information is sent to the external PLC control device. The external PLC control device calculates and converts the data to control the operation of the first adjusting motor 11 and the second adjusting motor 13.

[0030] When controlling the first adjusting motor 11, the housing of the first adjusting motor 11 is fixed to the fixed frame 9. The output shaft of the first adjusting motor 11 is connected to a lead screw. When the first adjusting motor 11 is started, the output shaft of the first adjusting motor 11 drives the lead screw to rotate. The lead screw extends into the interior of the first sliding frame 10 and forms a ball screw transmission structure to realize the longitudinal adjustment between the fixed frame 9 and the first sliding frame 10.

[0031] When controlling the second adjusting motor 13, the housing of the second adjusting motor 13 is fixed to the first sliding frame 10. The output shaft of the second adjusting motor 13 is connected to a lead screw. When the second adjusting motor 13 is started, the output shaft of the second adjusting motor 13 drives the lead screw to rotate. The lead screw extends into the interior of the second sliding frame 12 and forms a ball screw transmission structure to realize the lateral movement between the first sliding frame 10 and the second sliding frame 12.

[0032] By controlling the first adjusting motor 11 and the second adjusting motor 13, the output end of the dispensing pump 14 can be precisely aligned with the substrate gap X2, and quantitative control is performed according to the shape and position changes of the substrate gap X2. In order to better control the output height of the dispensing pump 14, the distance sensor 15 located on one side of the dispensing pump 14 can monitor the height of the dispensing pump 14, thus assisting the second adjusting motor 13 in making longitudinal height adjustments.

[0033] Example 2

[0034] In Embodiment 1, the fine-tuning function of the dispensing pump 14 is achieved through the first adjusting motor 11 and the second adjusting motor 13, and the CCD camera 2 and the distance sensor 15 are used to assist in measurement and adjustment. However, due to space and functional limitations, it is difficult to achieve a large range of longitudinal height adjustment using only the second adjusting motor 13. Therefore, referring to... Figure 2 The second support part X3 includes a support frame 3. A lifting cylinder 5 is bolted to one side of the support frame 3. A lifting frame 6 is fixedly mounted on the output shaft of the lifting cylinder 5. A slide rail 7 is fixedly mounted on one side of the lifting frame 6. A fixing groove 8 is opened on the outer end face of the slide rail 7. The fixing frame 9 is connected to the fixing groove 8 by bolts.

[0035] Furthermore, the first sliding frame 10 is slidably connected to the slide rail 7 to improve stability, and when adjusting, it is only necessary to loosen the bolts between the fixing groove 8 and the fixing frame 9 to slide along the slide rail 7 for quick manual adjustment.

[0036] Furthermore, an adjustment groove 4 is provided through the outer wall of the support frame 3. The adjustment groove 4 has an arc-shaped structure. The lifting cylinder 5 is fixed to the support frame 3 by two sets of bolts, one of which is fixedly installed inside the adjustment groove 4.

[0037] Working principle:

[0038] The lifting cylinder 5 is connected to the support frame 3 by two sets of bolts, and one set of bolts is fixed inside the adjustment groove 4. Therefore, when the bolts are loosened, the lifting cylinder 5 can be rotated along the adjustment groove 4 to adjust the angle of the output end of the lifting cylinder 5. The output end of the lifting cylinder 5 causes the assembly of the lifting frame 6, slide rail 7 and fixing groove 8 to tilt, which causes the fixing frame 9 fixed in the fixing groove 8 to tilt. The fixing frame 9 causes the assembly of the first sliding frame 10, second sliding frame 12 and dispensing pump 14 to tilt, thereby changing the tilt angle of the dispensing pump 14. After the adjustment is completed, the bolts can be tightened again.

[0039] When a large range of longitudinal adjustments is required, the lifting cylinder 5 is activated. The output end of the lifting cylinder 5 drives the entire assembly of the lifting frame 6, slide rail 7, and fixed groove 8 to move, thereby achieving a greater range of adjustment capabilities.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
