Description

Technical Field

[0001] This utility model relates to the field of gas meter manufacturing, specifically a gas meter diaphragm coating device. Background Technology

[0002] A gas meter is a device used to measure and record the amount of gas (such as natural gas or liquefied petroleum gas) used.

[0003] In the current technology, when gas meters are manufactured, glue is applied to the gas meter diaphragm to improve the sealing effect of the gas meter diaphragm and gas meter components. The glue application device mainly consists of a glue dispensing tube installed on the workbench, which is connected to a glue supply structure. The glue supply mechanism is equipped with a glue pump and electric heating inside, and the glue pump delivers glue to the glue dispensing tube.

[0004] However, during the adhesive application process, the gas meter diaphragm lacks proper positioning, causing it to shift and resulting in low adhesive application accuracy, which can easily lead to missed areas. Therefore, a gas meter diaphragm adhesive application device is proposed to address these issues. Utility Model Content

[0007] Preferably, a uniformly distributed mesh plate is fixedly connected to the bottom of the positioning groove, a negative pressure cavity is formed at the bottom of the positioning groove, a vacuum connector is fixedly connected to the bottom of the negative pressure cavity, and multiple air holes are formed at the beginning of the uniformly distributed mesh plate.

[0008] Preferably, a sliding seat is fixedly connected to the bottom side of the negative pressure chamber, the sliding seat passes through and is fixedly connected to the evenly distributed mesh plate, a top plate is slidably connected to the inner side wall of the top of the sliding seat, and a driving component is provided on the top seat to drive the top plate to move up and down.

[0009] Preferably, the driving assembly includes a push rod, which is fixed to the bottom side of the top plate. The push rod passes through the sliding seat and the top seat and is slidably connected to them. A trapezoidal block is fixed to the base at a position corresponding to the push rod.

[0010] Preferably, a spring is fixedly connected to the bottom side of the top plate, the spring is located inside the sliding seat, the spring is fixedly connected to the bottom inner wall of the sliding seat, and a pulley is rotatably connected to the bottom end of the top rod.

[0011] Preferably, it also includes two positioning seats and two push seats located on the four sides of the positioning groove. The positioning seats and the top side of the top seat are fixedly connected. An electric push rod is fixedly connected to the side of the top seat. The output end of the electric push rod is fixedly connected to the push seat.

[0012] The advantages of this utility model are:

[0013] 1. This utility model is provided with a base, motor, lead screw, base, top seat and positioning groove. In use, the bottom of the gas meter diaphragm is inserted into the positioning groove provided on the top seat, which can play the role of positioning the gas meter diaphragm, thereby improving the glue coating accuracy and reducing the situation of partial coating omission caused by gas meter diaphragm displacement.

[0014] 2. This utility model, by setting a uniformly distributed mesh plate and a vacuum connector, allows the vacuum connector to be connected to an external vacuum pump during use. The vacuum pump draws negative pressure inside the negative pressure chamber, and then the uniformly distributed mesh plate adsorbs the gas meter diaphragm, making it easier for the gas meter diaphragm to flatten and completely adhere to the uniformly distributed mesh plate. This can fix the gas meter diaphragm and keep it in a flat state, reducing the bending or unevenness of some areas due to its own elasticity. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] Specific implementation examples are given below.

[0024] Please see Figure 1-4 As shown, a gas meter diaphragm coating device includes a workbench 11, a support 12 fixedly connected to the top of the workbench 11, and a dispensing tube 13 installed on the side of the support 12; a base 14 fixedly connected to the top side of the workbench 11, a motor 15 fixedly connected to the side of the base 14, the output end of the motor 15 being fixedly connected to a lead screw 16, the lead screw 16 being rotatably connected inside the base 14, a base 17 being connected to the lead screw 16 via a ball screw nut pair, a top seat 18 fixedly connected to the top of the base 17, the top seat 18 being slidably connected to the base 14 via a slide rail, and a positioning groove 19 with the same shape as the gas meter diaphragm being opened on the top of the top seat 18;

[0025] In use, the motor 15 drives the lead screw 16 to rotate, which in turn drives the base 17 and the top seat 18 above the base 17 to move. This allows the top seat 18 to pass under the dispensing tube 13. The glue dispensing mechanism installed in the worktable 11 delivers glue to the dispensing tube 13 through a pipe. The top seat 18 moves at the bottom of the dispensing tube 13, and the dispensing tube 13 applies the glue to the gas meter diaphragm. The positioning groove 19 on the top seat 18 is inserted into the bottom of the gas meter diaphragm, which can position the gas meter diaphragm and improve the glue application accuracy, thereby reducing the possibility of missed areas due to gas meter diaphragm misalignment.

[0026] Furthermore, such as Figure 4As shown, a uniformly distributed mesh plate 21 is fixedly connected to the bottom of the positioning groove 19, a negative pressure chamber 22 is formed at the bottom of the positioning groove 19, a vacuum connector 23 is fixedly connected to the bottom of the negative pressure chamber 22, and multiple air holes are formed on the uniformly distributed mesh plate 21.

[0027] In use, the vacuum connector 23 is connected to an external vacuum pump. The vacuum pump draws negative pressure inside the negative pressure chamber 22 to form a negative pressure. Then, the evenly distributed mesh plate 21 adsorbs the gas meter diaphragm, which makes it easy for the gas meter diaphragm to flatten and completely adhere to the evenly distributed mesh plate 21. This can fix the gas meter diaphragm and keep it in a flat state, reducing the bending or unevenness of some areas due to its own elasticity.

[0028] Furthermore, such as Figure 4-5 As shown, a sliding seat 31 is fixedly connected to the bottom side of the negative pressure chamber 22. The sliding seat 31 passes through and is fixedly connected to the evenly distributed mesh plate 21. A top plate 32 is slidably connected to the inner side wall of the top of the sliding seat 31. A driving assembly is provided on the top seat 18 to drive the top plate 32 to move up and down. The driving assembly includes a push rod 42, which is fixedly connected to the bottom side of the top plate 32. The push rod 42 passes through the sliding seat 31 and the top seat 18 and is slidably connected to them. A trapezoidal block 41 is fixedly connected to the base 14 at a position corresponding to the push rod 42. A spring 52 is fixedly connected to the bottom side of the top plate 32. The spring 52 is located inside the sliding seat 31. The spring 52 is fixedly connected to the inner side wall of the bottom of the sliding seat 31. A pulley 51 is rotatably connected to the bottom end of the push rod 42.

[0029] In use, the top plate 32 can slide up and down inside the sliding seat 31. When the top seat 18 moves to the end of the base 14, this area is the feeding area. Its trapezoidal seat can squeeze and push the top rod 42 to slide upward, thereby driving the top plate 32 to move upward. The top plate 32 moves upward and lifts the gas meter diaphragm, thereby pushing it out of the positioning groove 19, which makes it convenient for the staff to remove the gas meter diaphragm. The spring 52 is used to facilitate the downward reset of the top plate 32, and the pulley 51 is used to reduce the friction between the top rod 42 and the trapezoidal block 41.

[0030] Furthermore, such as Figure 3 As shown, it also includes two positioning seats 61 and two push seats 62 located on the four sides of the positioning groove 19. The positioning seats 61 are fixedly connected to the top side of the top seat 18, and an electric push rod 63 is fixedly connected to the side of the top seat 18. The output end of the electric push rod 63 is fixedly connected to the push seat 62.

[0031] In use, the positioning seat 61 is used to position the two sides of the gas meter diaphragm. Then, the electric push rod 63 drives the seat 62 to move, thereby moving the gas meter diaphragm and assisting in positioning the gas meter diaphragm so that it can enter the positioning groove 19.

[0032] Furthermore, a linear module is installed on the bracket 12, and the dispensing tube 13 is installed on the linear module. The linear module can drive the dispensing tube 13 to move. The motor 15 is a servo motor. Based on the above settings, the dispensing position of the gas meter diaphragm can be moved and adjusted along the x-axis and y-axis.

[0033] Working principle: During use, the motor 15 drives the lead screw 16 to rotate, which in turn drives the base 17 and the top seat 18 above it to move. This allows the top seat 18 to pass under the dispensing tube 13. The adhesive dispensing mechanism installed in the worktable 11 delivers adhesive to the dispensing tube 13 through a pipe. The top seat 18 moves at the bottom of the dispensing tube 13, applying the adhesive to the gas meter diaphragm. The positioning groove 19 on the top seat 18 allows the bottom of the gas meter diaphragm to be inserted into it, thus positioning the diaphragm and improving adhesive application accuracy. This reduces the risk of missed areas due to diaphragm misalignment. The vacuum connector 23 connects to an external vacuum pump, which creates negative pressure in the negative pressure chamber 22, then evenly distributes the adhesive. The mesh plate 21 adsorbs the gas meter diaphragm, making it easy for the gas meter diaphragm to flatten and completely adhere to the evenly distributed mesh plate 21. This can fix the gas meter diaphragm and keep it in a flat state, reducing the bending or unevenness of some areas due to its own elasticity. In use, the top plate 32 can slide up and down inside the sliding seat 31. When the top seat 18 moves to the end of the base 14, this area is the feeding area. Its trapezoidal seat can squeeze and push the top rod 42 to slide upward, thereby driving the top plate 32 to move upward. The upward movement of the top plate 32 lifts the gas meter diaphragm, thereby pushing it out of the positioning groove 19, which makes it easy for the staff to remove the gas meter diaphragm. The spring 52 is used to facilitate the downward reset of the top plate 32, and the pulley 51 is used to reduce the friction between the top rod 42 and the trapezoidal block 41.

[0034] In use, the positioning seat 61 is used to position the two sides of the gas meter diaphragm. Then, the electric push rod 63 drives the seat 62 to move, thereby moving the gas meter diaphragm and assisting in positioning the gas meter diaphragm so that it can enter the positioning groove 19.
