Description

Technical Field

[0001] The present invention relates to the technical field of gas meter manufacturing, and in particular to a gas meter shell glue dispensing device manufactured based on the industrial Internet of Things. Background Art

[0002] During the installation of a gas meter housing, one of the steps involves dispensing glue onto the housing. This traditional method involves manual glue dispensing, but manual glue dispensing is not only inefficient but also prone to rapid solidification upon contact with air, leading to needle clogging and the inability to inject glue further into the meter housing. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the existing technology. The purpose is to provide a gas meter shell dispensing device manufactured based on the industrial Internet of Things. The set driving mechanism can drive the dispensing needle to realize automatic dispensing of the gas meter shell. At the same time, while the dispensing needle is waiting for the gas meter shell to be loaded and unloaded, the driving mechanism can drive the dispensing needle to be inserted into the alcohol bottle to prevent the glue remaining inside the dispensing needle from solidifying during the waiting process.

[0004] The present invention is achieved through the following technical solutions:

[0005] The gas meter shell dispensing device manufactured based on the industrial Internet of Things includes a driving mechanism and a dispensing assembly line. The output end of the driving mechanism is provided with a plurality of dispensing needles, and also includes the same number of alcohol bottles as the dispensing needles. When the gas meter shell is loaded and unloaded on the dispensing assembly line, the driving mechanism drives the dispensing needles to be inserted into the alcohol bottles respectively.

[0006] In the prior art, during the assembly process of the gas meter shell, it is necessary to perform glue dispensing operations inside the shell. The existing method is to perform glue dispensing operations manually. However, the manual operation method is not only inefficient, but also cannot continuously dispense glue to the gas meter shell because the operator needs to pick up and place the gas meter shell. Therefore, when the operator picks up and places the gas meter shell, the glue remaining in the needle tip easily comes into contact with air and solidifies, causing the needle tip to become clogged, and then making it impossible to continue to inject glue into the gas meter shell. To this end, the present technical solution designs a device for automatically dispensing glue to the gas meter shell, wherein a drive mechanism is provided to drive the glue dispensing needle to move up and down in the assembly area, insert the glue dispensing needle into the glue dispensing point in the gas meter shell, and realize automatic glue dispensing of the gas meter shell.

[0007] To ensure precise placement of the gas meter housing on the glue dispensing assembly line, this solution utilizes a robotic arm to handle the assembly and loading of the meter housings. Specifically, the robotic arm precisely transfers each meter housing to the glue dispensing assembly line. A glue needle is then inserted into the meter housing for glue dispensing. Finally, the robotic arm transfers each meter housing to the next assembly process for housing installation. Because glue readily solidifies upon contact with air, which can lead to clogged glue needles, this device minimizes glue dispensing time; the majority of the time is spent waiting for the meter housing to be loaded and unloaded on the glue dispensing assembly line. To prevent residual glue from solidifying in the needle while waiting for the meter housing to be transferred, this solution also incorporates an alcohol bottle containing alcohol within the assembly area. During both the transfer of the meter housing to the glue dispensing assembly line and the transfer of the glued meter housing to the next assembly line, a drive mechanism drives the glue needles until all are inserted into the alcohol bottle. Since the dispensing needle is completely immersed in the alcohol in the alcohol bottle, the glue solidified in the needle tube of the dispensing needle can quickly dissolve in the alcohol, thereby achieving the purpose of removing the solidified glue in the dispensing needle. In this way, during the loading and unloading process of the gas meter shell, the dispensing needle is always immersed in the alcohol bottle, effectively avoiding the blockage of the dispensing needle.

[0008] The dispensing assembly line includes a positioning jig seat for placing workpieces. The driving mechanism can drive the dispensing needle to move back and forth between the positioning jig seat and the alcohol bottle. A support seat is provided at the bottom of the positioning jig seat.

[0009] The glue dispensing assembly line in this technical solution is used to position the gas meter shell to be glued, ensuring that the glue dispensing needle on the driving mechanism can accurately glue the gas meter shell. The positioning fixture seat is provided with a number of slots for placing the gas meter shell. During operation, the robot in the assembly area can place the gas meter shell to be glued after the previous process is completed one by one in the slots of the positioning fixture seat, fix the gas meter shell on the positioning fixture seat, and finally use the glue dispensing needle to glue the gas meter shell on the positioning fixture seat.

[0010] Furthermore, a base is provided at the bottom of the driving mechanism, and the driving mechanism includes a mounting platform, a first robotic arm and a second robotic arm. The mounting platform is fixed on the top of the base, the first robotic arm is rotatably connected to the mounting platform, the second robotic arm is rotatably connected to the first robotic arm, and the dispensing needle is connected to the second robotic arm.

The hydraulic cylinder is connected to the movable shaft. The hydraulic cylinder can drive the movable shaft to move in the vertical direction on the second robotic arm, thereby realizing the adjustment of the height of the dispensing needle, ensuring that the dispensing needle can be inserted into the gas meter housing for dispensing during the dispensing process. At the same time, while waiting for the gas meter housing to be loaded and unloaded on the positioning fixture seat, the dispensing needle can be inserted into the alcohol bottle to prevent the dispensing needle from being blocked.

The interior of the sealing head is connected with the dispensing needle, and the sealing head has a conical structure. When the driving mechanism drives the dispensing needle to be inserted into the alcohol bottle, the sealing head located at the upper end of the dispensing needle can seal the bottle mouth of the alcohol bottle, thereby avoiding the volatilization of the alcohol in the alcohol bottle.

The adjustment block is an L-shaped structure, and the side wall of the adjustment block is connected to the side wall of the dispensing valve. A connecting block is placed at the bottom of the adjustment block, and a slider located in the slide groove is provided at the bottom of the connecting block.

At the same time, a first strip opening is also provided in the slide groove, and the first strip opening is distributed along the direction of the slide groove and is respectively connected to the upper and lower surfaces of the cross plate. A first strip opening is also provided on the top of the adjustment block. Two strip openings, the projection of the second strip opening in the vertical direction is perpendicular to the projection of the first strip opening in the vertical direction, and a bolt is also provided in the first strip opening of the horizontal plate, which vertically penetrates the first strip opening and the second strip opening in sequence and is connected with the butterfly nut, thereby fixing the adjustment block on the horizontal plate, and the second strip opening is provided for adjusting the position of the adjustment block on the connecting block, that is, when the butterfly nut is loosened, the adjustment block can move on the connecting block in a direction perpendicular to the horizontal plate, thereby realizing precise adjustment of the dispensing needle position, ensuring that the dispensing needle can be accurately inserted into the gas meter housing to be dispensed, and realizing precise dispensing of the gas meter housing.

[0021] Furthermore, it also includes a mounting plate, a base plate and two mounting pillars, the base plate is located between the support seat and the base, the mounting pillars are vertically fixed on the two end surfaces of the base plate, the mounting plate is located directly above the base plate, and the two ends of the mounting plate are respectively connected to the two mounting pillars; a notch is also provided on one side of the mounting plate, and a fixing ring is also provided at the bottle mouth of the alcohol bottle, the outer diameter of the fixing ring is larger than the width of the notch, and the bottle mouth of the alcohol bottle is located in the notch of the mounting plate.

[0022] In order to ensure the stability of the alcohol bottle and prevent the alcohol bottle from tipping over when the dispensing needle is inserted into the alcohol bottle, a placement rack for placing the alcohol bottle is provided between the support seat and the base. The placement rack includes a mounting plate, a bottom plate and two mounting pillars. In order to facilitate hanging the alcohol bottle on the mounting plate, a notch is provided on the side wall of the mounting plate facing the support seat, and a fixing ring is provided at the bottle mouth of the alcohol bottle. The outer diameter of the fixing ring is larger than the width of the notch. Therefore, when placing the alcohol bottle, the bottle mouth of the alcohol bottle below the fixing ring is inserted into the notch, and the alcohol bottle is clamped in the notch using the fixing ring, thereby realizing quick installation of the alcohol bottle and facilitating replacement of the alcohol bottle.

[0023] Furthermore, a protective plate with a Z-shaped cross-section is provided between the base plate and the support seat. The top surface of the protective plate is located on the positioning fixture seat and is distributed along the direction of the mounting plate.

[0024] Since the dispensing needle needs to move back on the alcohol bottle and the positioning jig seat under the drive of the driving mechanism, in order to prevent the glue attached to the end of the dispensing needle from dripping onto the assembly area during the movement of the dispensing needle, a protective plate is set between the alcohol bottle and the positioning jig seat.

DETAILED DESCRIPTION

[0047] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with examples and drawings. The exemplary embodiments of the present invention and their descriptions are only used to explain the present invention and are not intended to limit the present invention.

[0048] Example 1

[0049] like Figure 1 、 Figure 2 As shown, the present invention includes a driving mechanism and a dispensing assembly line. The output end of the driving mechanism is provided with a plurality of dispensing needles 14. It also includes alcohol bottles 4 with the same number as the dispensing needles 14. When the gas meter housing 17 is loaded and unloaded on the dispensing assembly line, the driving mechanism drives the dispensing needles 14 to be inserted into the alcohol bottles 4 respectively.

[0050] In the prior art, during the assembly process of the gas meter shell, it is necessary to perform glue dispensing operations inside the shell. The existing method is to perform glue dispensing operations manually. However, the manual operation method is not only inefficient, but also cannot continuously dispense glue to the gas meter shell because the operator needs to pick up and place the gas meter shell. Therefore, when the operator picks up and places the gas meter shell, the glue remaining in the needle tip easily comes into contact with air and solidifies, causing the needle tip to become clogged, and then making it impossible to continue to inject glue into the gas meter shell. To this end, the present technical solution designs a device for automatically dispensing glue to the gas meter shell, wherein a drive mechanism is provided to drive the glue dispensing needle 14 to move up and down in the assembly area, insert the glue dispensing needle 14 into the glue dispensing point in the gas meter shell 17, and realize automatic glue dispensing of the gas meter shell 17.

[0051] In order to ensure that the gas meter housing 17 can be accurately placed on the glue dispensing assembly line, the present technical solution uses a manipulator to pick up the gas meter housing 17 one by one to load and unload it. That is, the manipulator uses the manipulator to accurately transfer the gas meter housing 17 to be glued one by one to the glue dispensing assembly line, and then uses the glue dispensing needle 14 to be inserted into the gas meter housing 17 for glue dispensing. Finally, the manipulator uses the manipulator to transfer the glued gas meter housing 17 to the next process for housing installation. Since glue is easy to solidify after contact with air, the glue dispensing needle 14 is blocked. However, the glue dispensing needle 14 of the present device takes a short time to dispense glue, and most of the time is spent waiting for the gas meter housing 17 to be loaded and unloaded on the glue dispensing assembly line. In order to prevent the glue remaining in the glue dispensing needle 14 from solidifying due to air while the glue dispensing needle 14 is waiting for the transfer of the gas meter housing 17, the present technical solution also provides an alcohol bottle 4 in the assembly area, and the alcohol bottle 4 contains alcohol. When the manipulator is used to transfer the gas meter housing 17 to the glue dispensing assembly line and the glued gas meter housing 17 is transferred to the next assembly line, the driving mechanism is used to drive the glue dispensing needle 14 to be completely inserted into the alcohol bottle 4. Since the glue dispensing needle 14 is completely inserted into the alcohol bottle 4, the alcohol bottle 4 can be used to immerse the glue dispensing needle 14 in alcohol, and the glue solidified in the glue dispensing needle 14 tube can be quickly dissolved in the alcohol, thereby achieving the purpose of removing the glue solidified in the glue dispensing needle 14. In this way, during the process of loading, unloading and transferring the gas meter housing 17, the glue dispensing needle 14 is always immersed in the alcohol bottle 4, effectively avoiding the problem of the glue dispensing needle 14 being blocked.

During operation, the robot in the assembly area can place the gas meter shell 17 to be glued after the previous process is completed one by one in the slots of the positioning fixture seat 2, fix the gas meter shell 17 on the positioning fixture seat 2, and finally use the glue dispensing needle 14 to glue the gas meter shell 17 located on the positioning fixture seat 2.

[0068] Since the dispensing needle 14 needs to move back on the alcohol bottle 4 and the positioning jig seat 2 under the drive of the driving mechanism, in order to prevent the glue attached to the end of the dispensing needle 14 from dripping onto the assembly area during the movement of the dispensing needle 14, a protective plate 3 is set between the alcohol bottle 4 and the positioning jig seat 2. When the dispensing needle 14 moves toward the alcohol bottle 4, the glue dripping from the dispensing needle 14 can fall on the protective plate 3, which is convenient for subsequent cleaning.

[0069] Example 2

[0070] like Figures 3 to 6 As shown, on the basis of Example 1, a first telescopic member 21 is provided on the inner bottom of the alcohol bottle 4; a second telescopic member 24 is also provided on the inner wall of the alcohol bottle 4, one end of the second telescopic member 24 is connected to the inner wall of the alcohol bottle 4, and the other end is provided with a clamping unit, and a connecting unit is also provided between the first telescopic member 21 and the second telescopic member 24. When the dispensing needle 14 is inserted into the alcohol bottle 4 and the first telescopic member 21 is pressed down, the gas in the first telescopic member 21 can be transferred to the second telescopic member 24 through the connecting unit, forcing the second telescopic member 24 to drive the clamping unit to clamp on the circumferential outer wall of the dispensing needle 14.

[0071] While waiting for the gas meter housing 17 to be placed on the positioning fixture seat 2, the dispensing needle 14 is inserted into the alcohol bottle 4. After the gas meter housing 17 is placed, the dispensing needle 14 is pulled out of the alcohol bottle 4. Alcohol will be attached to the outer wall of the dispensing needle 14. As a result, when the dispensing needle 14 is dispensing glue on the gas meter housing 17, the alcohol attached to the outer wall of the dispensing needle 14 will easily flow into the dispensing point of the gas meter housing 17, dissolving the glue that has just been applied, thereby reducing the bonding ability of the glue. To this end, the present technical solution improves the internal structure of the alcohol bottle 4, and a first telescopic part 21 and a second telescopic part 24 are provided in the alcohol bottle 4. The first telescopic part 21 and the second telescopic part 24 are both bellows, and the bellows can be expanded and contracted in the axial direction during the internal inflation or deflation process, that is, when the dispensing needle 14 is inserted into the alcohol bottle 4, the alcohol in the alcohol bottle 4 dissolves the glue attached to the needle head of the dispensing needle 14 to prevent the glue from solidifying and causing the needle head of the dispensing needle 14 to be blocked. When the dispensing needle 14 continues to move downward, the needle head of the dispensing needle 14 acts on the first telescopic part 21 and compresses the first telescopic part 21 downward. When the first telescopic part 21 is compressed by the dispensing needle 14, the gas in the first telescopic part 21 transfers the gas in the first telescopic part 21 to the second telescopic part 24 through the provided connecting unit, forcing the second telescopic part 24 to expand and stretch along its axial direction, thereby driving the clamping unit to move toward the outer wall of the dispensing needle 14, and finally clamped on the outer wall of the dispensing needle 14.

[0072] When the dispensing needle 14 needs to continue dispensing glue on the gas meter housing 17, the alcohol attached to the outer wall of the dispensing needle 14 is scraped off by the provided clamping unit during the process of pulling the dispensing needle 14 out of the alcohol bottle 4, thereby avoiding the alcohol attached to the outer wall of the dispensing needle 14 dripping onto the positioning jig seat 2 and affecting the bonding ability of the glue during the process of removing the dispensing needle 14 from the alcohol bottle 4.

[0073] At the same time, during long-term use, impurities will inevitably adhere to the outer wall of the dispensing needle 14. Since the alcohol contained in the alcohol bottle 4 cannot ensure that the outer wall of the dispensing needle 14 is completely soaked, the impurities attached to the outer wall of the dispensing needle 14 that are not soaked in alcohol are easily dropped into the gas meter housing 17 during the dispensing process, affecting the assembly quality of the gas meter housing 17. To this end, in the process of inserting the dispensing needle 14 into the alcohol bottle 4 and compressing the first telescopic member 21 in the present technical solution, the second telescopic member 24 drives the clamping unit to clamp on the outer wall of the dispensing needle 14, and the clamping unit is close to the bottle mouth of the alcohol bottle 4, so that in the process of removing the dispensing needle 14 from the alcohol bottle 4, the provided clamping unit can not only scrape off the alcohol attached to the dispensing needle 14, but also clean up the impurities attached to the outer wall of the dispensing needle 14, thereby improving the assembly quality of the gas meter housing 17.

[0074] The connecting unit includes a connecting tube 32 and a conduit 22. The connecting tube 32 passes through the inner bottom of the alcohol bottle 4 and is connected to the interior of the first telescopic member 21. One end of the conduit 22 is connected to the connecting tube 32, and the other end is connected to the second telescopic member 24. An adjusting unit is also provided in the connecting tube 32, and the adjusting unit is used to adjust the connection or closure between the conduit 22 and the connecting tube 32.

[0075] When the dispensing needle 14 presses down the first telescopic part 21, the gas in the first telescopic part 21 is squeezed into the connecting tube 32, and the gas entering the connecting tube 32 is then transmitted to the second telescopic part 24 through the provided conduit 22, forcing the second telescopic part 24 to collide and stretch, thereby driving the clamping unit to clamp the outer wall of the dispensing needle 14; and when the driving mechanism drives the dispensing needle 14 to move out of the alcohol bottle 4, after the pressure acting on the first telescopic part 21 is removed, in order to prevent the gas entering the second telescopic part 24 from flowing back into the first telescopic part 21, thereby causing the clamping unit to be unable to continue to clamp the outer wall of the dispensing needle 14, and thus unable to remove the dispensing needle. In order to remove the alcohol and impurities on the outer wall of the dispensing needle 14, an adjusting unit is further provided in the connecting tube 32. When the dispensing needle 14 needs to be removed from the alcohol bottle 4, the adjusting unit is used to disconnect the connecting tube 32 and the conduit 22. In this way, after the dispensing needle 14 removes the pressure on the first telescopic part 21, the gas introduced into the second telescopic part 24 cannot flow back, thereby ensuring that the second telescopic part 21 can drive the clamping unit to continuously clamp the outer wall of the dispensing needle 14. In this way, it is ensured that the clamping unit can continuously contact the outer wall of the dispensing needle 14 during the process of removing the dispensing needle 14 from the alcohol bottle 4, thereby achieving the cleaning of alcohol and impurities on the outer wall of the dispensing needle 14.

[0076] The adjusting unit includes a cylinder 28, a blocking block 31, a first elastic member 30 and a movable block 27. The cylinder 28 is fixed at the bottom of the connecting pipe 32. The output end 29 of the cylinder 28 is connected to the movable block 27. The blocking block 31 and the movable block 27 are both located in the connecting pipe 32, and the outer diameter of the blocking block 31 is consistent with the inner diameter of the connecting pipe 32. One end of the first elastic member 30 is connected to the blocking block 31, and the other end is connected to the movable block 27.

[0077] When the dispensing needle 14 is inserted into the alcohol bottle 4 and the first telescopic part 21 is pressed down, the gas in the first telescopic part 21 is pressed into the connecting tube 32, squeezing the blocking block 31, so that the blocking block 31 moves below the connection point between the conduit 22 and the connecting tube 32, and forces the blocking block 31 to compress the first elastic part 30. At this time, the gas entering the connecting tube 32 enters the conduit 22 through the connection point between the conduit 22 and the connecting tube 32, and then enters the second telescopic part 24, thereby achieving the purpose of inflating the second telescopic part 24.

[0078] When the dispensing needle 14 is removed from the alcohol bottle 4, the dispensing needle 14 removes the force on the first telescopic part 21, and under the action of the first elastic part 30, it can push the blocking block 31 to move back, blocking the connection between the conduit 22 and the connecting pipe 32, thereby preventing the gas in the second telescopic part 24 from flowing back into the first telescopic part 21.

[0079] At the same time, a transmission is provided at the bottle mouth of the alcohol bottle 4, and a sensor is connected to the cylinder 28. When the dispensing needle 14 is removed from the alcohol bottle 4, the sensor controls the cylinder 28 to work, so that the output end 29 of the cylinder 28 pulls the movable block 27 to move downward. During the movement of the movable block 27, the first elastic member 30 is used to pull the blocking block 31 to move along, thereby moving the blocking block 31 to below the connection point between the conduit 22 and the connecting pipe 32. At this time, the gas in the second telescopic member 24 can flow back to the first telescopic member 21 through the conduit 22, forcing the first telescopic member 21 and the second telescopic member 24 to return to their initial state.

[0080] In order to ensure that the first telescopic member 21 and the second telescopic member 24 can quickly restore to their initial state, a second elastic member is provided in the first telescopic member 21 and the second telescopic member 24. The second elastic members are distributed along the axial direction of the first telescopic member 21 and the second telescopic member 24, and are connected to the first and second telescopic members 21 and 24 at both ends. When the first telescopic member 21 is compressed by the dispensing needle 14, the second elastic member located in the first telescopic member 21 is in a compressed state. Therefore, after the pressure of the dispensing needle 14 on the first telescopic member 21 is removed, the first telescopic member 21 can be quickly restored to its initial state under the action of the second elastic member; and when gas is introduced into the second telescopic member 24 to force the second telescopic member 24 to be in a stretched state, the second elastic member located in the second telescopic member 24 is in a stretching device. Therefore, under the action of the second elastic member, the second telescopic member 24 can be pulled to quickly restore to its initial state.

[0081] The clamping unit includes a clamping block 23 , a clamping surface of the clamping block 23 is provided with an arc-shaped groove matching the outer wall of the dispensing needle 14 , and a gasket 26 is provided in the arc-shaped groove.

[0082] A second telescopic part 24 is provided on both sides of the inner wall of the alcohol bottle 4. The arc-shaped grooves of the two clamping blocks 23 can form a circle that matches the outer diameter of the dispensing needle 14. Therefore, under the action of the second telescopic part 24, the clamping block 23 can be clamped on the outer wall of the dispensing needle 14, and the provided gasket 26 can increase the contact ability between the clamping block 23 and the outer wall of the dispensing needle 14.

[0083] A cross bar 25 is further provided on the inner wall of the alcohol bottle 4 , and the cross bar 25 passes through the clamping block 23 .

[0084] In order to improve the stability of the second telescopic member 24 during movement, a cross bar 25 is provided to ensure that the clamping block 23 can move horizontally in the alcohol bottle 4.

The object platform sends the production and manufacturing perception information to the user platform through the sensor network platform, management platform, and service platform that interact in sequence, and receives the control information issued by the user platform through the service platform, management platform, and sensor network platform.

[0087] Example 4

[0089] 1) Use a manipulator to place the gas meter housings 17 one by one on the positioning fixture seat 2;

[0090] 2) The driving mechanism drives the dispensing needle 14 to be inserted into the dispensing position of the gas meter housing 17 located on the positioning fixture seat 2, and the dispensing valve 13 is used to deliver glue into the dispensing needle 14 to dispense glue on the gas meter housing 17;

[0091] 3) After the dispensing needle 14 completes dispensing on the gas meter housing 17, the driving mechanism drives the dispensing needle 14 to be inserted into the alcohol bottle 4;
