Description

Technical Field

[0001] This utility model relates to the field of adhesive coating machine technology, specifically to an adhesive coating machine for piezoresistive sensor strain gauges. Background Technology

[0002] A piezoresistive sensor is a sensor that utilizes the piezoresistive effect of semiconductor materials. When a semiconductor material is subjected to pressure, its resistivity changes. This type of sensor mainly consists of piezoresistive elements such as silicon wafers, and converts the resistance change caused by pressure into a voltage signal output through circuits such as a Wheatstone bridge.

[0003] A piezoresistive sensor strain gauge applicator is a piece of equipment used in the production process of piezoresistive sensors. Its main function is to precisely apply adhesive to the strain gauge, ensuring that the strain gauge is firmly attached to the corresponding position on the sensor. This applicator uses a precise control system to control the amount of adhesive applied, the application position, and the application method.

[0004] Existing piezoresistive sensor strain gauge patching and gluing machines still have the following problems: it is inconvenient to stack the strain gauges before gluing. Usually, before applying glue to the strain gauges, workers need to manually stack them, which makes the workload very large and prone to errors. To address the above problems, a piezoresistive sensor strain gauge patching and gluing machine is proposed. Utility Model Content

[0033] Combination Figure 1 , Figure 2 and Figure 4 This utility model discloses a piezoresistive sensor strain gauge patch coating machine, comprising a base plate 2, with L-shaped plates 5 fixedly connected to the top center and both ends of the base plate 2. A glue tank 7 is fixedly connected between the L-shaped plates 5, securing the glue tank 7. A pressure pump 9 is fixedly connected to the top center of the glue tank 7, and is mounted on the glue tank 7. An air pipe 8 is provided at the output end of the pressure pump 9, with one end of the air pipe 8 penetrating and fixedly connected to the glue tank 7. Air pressure is generated through the pressure pump 9 and the air pipe 8. A feed pipe 11 is penetrating and fixedly connected to the top front end of the glue tank 7, with a sealing cap 10 threadedly connected to the top of the feed pipe 11. Glue is replenished through the feed pipe 11, and the sealing cap 10 seals the feed. The pipe 11 has a second groove 20 at one end of the second connecting plate 12. The inner wall of the second groove 20 is slidably connected to the rubber plate 28, allowing the rubber plate 28 to slide stably. The slide rail 14 has a first groove 16 on one side. The inner wall of the first groove 16 is slidably connected to the third connecting plate 18, allowing the third connecting plate 18 to slide stably. The top center of the base plate 2 is fixedly connected to the conveyor belt 1, which is installed on the base plate 2. The rear center of the rear L-shaped plate 5 has a control panel 6, which is electrically connected to the conveyor belt 1, the pressure pump 9, and the brake motor 19. The control panel 6 is used to control the opening and closing of the conveyor belt 1, the pressure pump 9, and the brake motor 19.

[0034] Combination Figures 2-4A uniformly distributed support rod 3 is fixedly connected to the top center left of the base plate 2. A first connecting plate 4 is fixedly connected to the top of the support rod 3, and the first connecting plate 4 is fixed by the support rod 3. Slide rails 14 are fixedly connected to the top left and right sides of the first connecting plate 4. A third connecting plate 18 is slidably connected to one side of the slide rail 14. A uniformly distributed tooth 17 is provided at the bottom of one side of the third connecting plate 18, and the tooth 17 is installed through the third connecting plate 18. A brake motor 19 is fixedly connected to the bottom center of the first connecting plate 4. A gear 13 is fixedly connected to the output end of the brake motor 19. The brake motor 19 drives the gear 13, thereby causing the gear 13 to rotate. The gear 13 meshes with the tooth 17. The rotation of the gear 13 causes the tooth 17 and the third connecting plate 18 to move. A connecting frame 15 is fixedly connected to one end of the third connecting plate 18, and a second connecting plate 12 is fixedly connected to the other end of the connecting frame 15. A rubber plate 28 is slidably connected to one end of the second connecting plate 12. By moving the second connecting plate 12 and the rubber plate 28 towards the center, the strain gauges can be aligned.

[0035] Combination Figure 1 and Figure 5 An elastic component is provided at the top center of the inner wall of the glue tank 7. The elastic component includes a sleeve 22, the top of which is fixedly connected to the glue tank 7. The sleeve 22 is installed through the glue tank 7. The inner wall of the sleeve 22 is coated with a Teflon coating 27, which prevents the sleeve 22 and the silicone stopper 26 from sticking together. The silicone stopper 26 is slidably connected to the bottom of the inner wall of the sleeve 22. A spring 21 is fixedly connected to the top of the silicone stopper 26. The top of the spring 21 is fixedly connected to the glue tank 7. The elastic force pushes the silicone plug 26 downward to block the glue tank 7. A threaded tube 23 is threaded through and connected to the bottom center of the glue tank 7. The top of the outer ring of the threaded tube 23 has evenly distributed feed ports 25. The glue enters the threaded tube 23 through the feed ports 25. A nozzle 24 is fixedly connected to the bottom of the threaded tube 23, and the top of the threaded tube 23 is in contact with the silicone plug 26. The glue is sprayed out through the nozzle 24. The silicone plug 26 is in complete contact with the threaded tube 23 to prevent glue leakage.

[0036] Working principle: When the strain gauges are delivered to the second connecting plate 12, stop. Turn on the brake motor 19. The output end of the brake motor 19 rotates, driving the gear 13 to rotate. This drives the gear 17, the third connecting plate 18, and the rubber plate 28 to move along the first slide groove 16 towards the center until the strain gauges are aligned. After the strain gauges are aligned, the conveyor belt 1 delivers the strain gauges to the bottom of the adhesive tank 7. Turn on the pressure pump 9. Under the action of the pressure pump 9, the adhesive can be sprayed from the nozzle 24 onto the top of the strain gauges for application. When the nozzle 24 needs to be replaced, rotate the threaded tube 23 and the nozzle 24 to remove the nozzle 24. As the threaded tube 23 moves downward, the spring 21 pushes the silicone plug 26 downward. When the threaded tube 23 is completely removed from the adhesive tank 7, the silicone plug 26 can completely block the adhesive tank 7, thereby preventing the adhesive from leaking out and causing other parts to stick.
