Description

Technical Field

[0001] This utility model belongs to the technical field of power module production equipment. Specifically, this utility model relates to a power module silicone gel curing detection device. Background Technology

[0002] In the power module production process, one step involves filling the product with silicone gel. After filling, the product is placed in a high-temperature oven to heat and solidify the silicone gel. Once solidified, the silicone gel provides insulation and vibration protection for the product. This silicone gel is a mixture of two components in a 1:1 ratio, solidified at a temperature above 120°C. If the ratio is imbalanced, the silicone gel will not solidify regardless of the temperature, failing to protect the product and causing its performance to fail. If this is not detected in time, the dispensing equipment will continue production, resulting in a large number of scrapped products. The dispensing equipment itself cannot detect any imbalance in the ratio 100% of the time, therefore, this process carries a certain risk of product scrapping.

[0003] In existing technologies, flow valves are added to dispensing equipment to control dispensing. However, this method cannot guarantee 100% that the dispensing will not be abnormal or malfunction, and the equipment will not alarm. At the same time, there is no special device to detect whether the silicone gel ratio is unbalanced after dispensing, and a foolproof closed loop cannot be formed.

[0004] Chinese Patent Application No. 202420931702.0 discloses a photosensitive hydrogel photocuring device, including an intermediate fixing base, a light-emitting head, a base, and a housing. A control component is disposed on the intermediate fixing base. One end of the intermediate fixing base along its length is connected to the light-emitting head, and the other end is connected to the housing. The end of the housing away from the light-emitting head is connected to the base. The light-emitting head is connected to the control component. A cavity for placing a battery is provided inside the housing. One end of the battery is connected to the control component, and the other end is connected to the base. However, the technical solution disclosed in this patent document also fails to address the aforementioned shortcomings.

[0005] This invention provides a device for detecting the curing of silicone gel in power modules, specifically addressing how to effectively detect whether silicone gel has cured and promptly identify any abnormalities. Utility Model Content

[0006] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention provides a power module silicone gel curing detection device, the purpose of which is to ensure effective detection of whether the silicone gel has cured and to promptly identify abnormalities.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a power module silicone gel curing detection device, including a telescopic actuator, a connecting mechanism connected to the telescopic actuator, and a pressure sensor disposed on the connecting mechanism for contacting the silicone gel inside the power module.

[0008] The telescopic actuator is a cylinder.

[0009] The connecting mechanism includes a first connecting block and a second connecting block connected to each other. The first connecting block is connected to the telescopic actuator, and the pressure sensor is mounted on the second connecting block.

[0010] The first connecting block and the second connecting block are fixedly connected by bolts.

[0011] The second connecting block is L-shaped.

At the same time, adding this detection device can directly eliminate manual full inspection, avoiding the waste of manpower. Attached Figure Description

[0018] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the concept and technical solution of this utility model, and to facilitate its implementation.

[0019] It should be noted that in the following embodiments, the terms "first" and "second" do not represent an absolute distinction in structure and / or function, nor do they represent the order of execution, but are merely for the convenience of description.

[0020] like Figure 1and Figure 2 As shown, this utility model provides a power module silicone gel curing detection device, including a telescopic actuator 1, a connecting mechanism connected to the telescopic actuator 1, and a pressure sensor 2 disposed on the connecting mechanism for contacting the silicone gel inside the power module. The pressure sensor 2 presses against the silicone gel, feeding back the force on the silicone gel and transmitting the pressure data through a pressure data transmission line 6 to form pressure data, thus effectively determining whether the silicone gel has cured.

[0021] like Figure 1 and Figure 2 As shown, the telescopic actuator 1 is a cylinder, and the cylinder body of the telescopic actuator 1 is connected to the receiving robotic arm of the glue dispensing equipment by bolts.

[0022] like Figure 1 and Figure 2 As shown, the connecting mechanism includes a first connecting block 3 and a second connecting block 4 connected together. The first connecting block 3 is connected to the telescopic actuator 1, and the pressure sensor 2 is mounted on the second connecting block 4. The first connecting block 3 is fixedly connected to the piston rod of the cylinder, and the first connecting block 3 and the second connecting block 4 are fixedly connected by multiple bolts. The pressure sensor 2 is fixedly mounted on the second connecting block 4 by bolts. The conical head of the pressure sensor 2 is used to contact the silicone gel inside the power module, and the pressure data transmission line 6 of the pressure sensor 2 is connected to the control system of the dispensing equipment.

[0023] like Figure 1 and Figure 2 As shown, the second connecting block 4 is L-shaped, and multiple through holes are provided on the second connecting block 4 to allow bolts to pass through.

[0024] The power module silicone gel curing detection device described above is secured to the receiving robotic arm of the dispensing equipment by screws through four screw holes on the cylinder body. The receiving stroke of the robotic arm is the stroke of the silicone gel curing detection device, enabling it to detect each power module product.

[0025] When the power module product arrives at the robotic arm's receiving position, the silicone gel curing detection device detects whether the silicone gel has cured. First, the control system of the dispensing equipment sends a signal, and compressed air enters the telescopic actuator 1. The telescopic actuator 1 extends, and the pressure sensor 2 is fixed to the end of the telescopic actuator 1 through the connecting mechanism. Therefore, the pressure sensor 2 moves downward with the telescopic actuator 1, and the cone of the pressure sensor 2 descends until it presses against the silicone gel inside the product.

[0026] When the cone of pressure sensor 2 presses against the silicone gel, pressure sensor 2 will detect pressure data. Pressure data transmission line 6 transmits the pressure data to the control system of the dispensing equipment in real time. The control system of the dispensing equipment analyzes the data uploaded and determines whether the silicone gel has cured based on the standard value of silicone gel curing resistance.

[0027] When the control system of the dispensing equipment receives the data transmitted through the pressure data transmission line 6, the control system of the dispensing equipment will also send a signal to stop the supply of compressed air to the telescopic actuator 1. The telescopic actuator 1 retracts, causing the pressure sensor 2 to rise together and detach from the product. The robotic arm of the equipment then collects the product and places it in different product areas according to the silicone gel solidification determination command issued by the control system of the dispensing equipment.

[0028] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention; or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
