Description

Technical Field

[0001] The present invention relates to the technical field of sensor assembly equipment, in particular to a sensor sealing assembly equipment with a gluing self-inspection function. Background Art

[0002] Sensor assembly has always been a very important process in the sensor production process. Rigorous and qualified assembly is an important standard for sensor production. In traditional industrial production, the assembly process is usually carried out manually, using positioning fixtures and other methods, as well as manual gluing and installation. This leads to a large number of errors in the product production process.

[0003] Existing sensor assembly uses a manual cleaning, gluing and placement workflow, which may result in inadequate cleaning or uneven gluing areas during cleaning and gluing, leading to quality problems during sensor sealing assembly and subsequent inadequate sealing. Summary of the Invention

[0004] The object of the present invention is to provide a sensor sealing assembly device with a gluing self-checking function to solve the problems raised in the prior art.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A sensor sealing assembly device with a gluing self-check function includes a body, a first feed inlet is provided at the bottom of the body, a second feed inlet is provided at the top of the body, an assembly cavity is provided between the first feed inlet and the second feed inlet, an assembly component is provided in the assembly cavity, and an observation door is provided on one side of the assembly cavity;

[0007] The sensor component is delivered to the assembly cavity through the first feed port, and the sealing cover is delivered to the assembly cavity through the second feed port. The sensor component and the sealing cover are processed by the assembly component in the assembly cavity, so that the sensor component and the sealing cover are sealed and assembled in the assembly cavity. During the assembly, the sealing cover is cleaned and the sensor component is sprayed with glue, thereby improving the efficiency of the sensor sealing assembly. At the same time, negative pressure is used to discharge the gas in the sealing cover. During the discharge process, the air drives the glue to flow, further allowing the glue to fill the gap between the sealing cover and the sensor component, thereby further improving the sealing assembly quality of the sensor component.

[0008] Preferably, the assembly component includes a first delivery pipe and a second delivery pipe, the first delivery pipe is located at the bottom of the assembly chamber and is communicated with the first feed port, the second delivery pipe is located at the top of the assembly chamber and is communicated with the second feed port, the axes of the first delivery pipe and the second delivery pipe are in a coincident state, and an assembly body is provided on the outer wall of the second delivery pipe;

[0009] When the sensor assembly moves to the first conveying pipe, it is then conveyed to the assembly chamber through the first conveying pipe. After the sensor assembly moves to the assembly table, the sealing cover is conveyed to the assembly chamber through the second conveying pipe. Since the axes of the first conveying pipe and the second conveying pipe are in a coincident state, the axes of the sensor assembly and the sealing cover are also in a coincident state, so that the sealing cover can fall accurately above the sensor assembly.

[0010] Preferably, a plurality of rotating rollers are respectively provided in the first feed port and the second feed port, the first feed port is used to convey the sensor assembly, the second feed port is used to convey the sealing cover, a first hydraulic cylinder is provided at the bottom of the first conveying pipe, a push plate is provided on the push rod of the first hydraulic cylinder, the push plate is slidingly and sealingly connected to the inner wall of the first conveying pipe, a second hydraulic cylinder is provided at the top of the second conveying pipe, the push rod of the second hydraulic cylinder is slidingly and sealingly connected to the second conveying pipe, an extrusion plate is provided on the push rod of the second hydraulic cylinder, a rotating motor is provided on the side of the extrusion plate close to the second hydraulic cylinder, and the drive shaft of the rotating motor is connected to the extrusion plate;

[0011] The rotating roller rotates under the control of the controller, so that during the rotation of the rotating roller, the sensor assembly and the sealing cover are driven to move along the first feed inlet and the second feed inlet respectively. When the sensor assembly moves above the push plate, the push rod of the first hydraulic cylinder immediately pushes the push plate to move, and the push plate drives the sensor assembly to move along the first conveying pipe, so that the push plate conveys the sensor assembly to the assembly table.

[0012] When the sensor assembly moves to the assembly table, the sealing cover enters the second conveying pipe through the rotating roller, and then the sealing cover falls along the second conveying pipe to the top of the assembly. Then the push rod of the second hydraulic cylinder drives the extrusion plate to move, so that the extrusion plate contacts the sealing cover during the movement, and starts the rotating motor. The driving shaft of the rotating motor drives the extrusion plate to rotate, and the extrusion plate drives the sealing cover to rotate when the extrusion plate rotates, so that the sealing cover contacts the surface of the assembly with friction, thereby completing the surface cleaning of the sealing cover.

[0013] Preferably, an assembly table is provided inside the assembly cavity, the center of the assembly table is connected to the first conveying pipe, and a plurality of folding grooves are provided around the assembly table. The center height of the folding groove is smaller than the height of the folding groove close to the first conveying pipe, and the height of the folding groove close to the first conveying pipe is smaller than the height of the folding groove close to the side wall of the assembly cavity.

[0014] Preferably, the assembly body is composed of an assembly ring and a plurality of movable groups, the movable groups are located below the assembly ring, a plurality of racks are provided on the outer wall of the assembly ring, a driving cavity is provided in the inner wall of the assembly cavity, a driving motor is provided in the driving cavity, a rotating gear is provided on the driving shaft of the driving motor, the rotating gear is fitted with the rack, and the assembly ring is slidably connected to the second conveying pipe through the rotating gear and the rack;

[0015] When the assembly is being assembled, the controller controls the drive motor to start, and the drive shaft of the drive motor drives the rotating gear to rotate. When the rotating gear rotates, it engages with the rack on the assembly ring, and then the assembly ring moves under the action of the rotating gear, and the assembly ring then drives several movable groups to move to the side close to the assembly table;

[0016] When the sealing cover is cleaned and the glue spraying port is finished, the assembly is reset. At this time, the controller controls the driving motor to reverse, and the driving shaft of the driving motor drives the rotating gear to reverse. When the rotating gear rotates, it engages with the rack on the assembly ring, and then the assembly ring moves under the action of the rotating gear. The assembly ring then drives several movable groups to move to the side away from the assembly table.

[0017] During the resetting process of the assembly ring, several movable groups are driven to reset, and then the support frame formed by several second movable plates is disbanded, so that the sealing cover loses the support function of the support frame, and then the sealing cover falls to the place where the glue is sprayed, so that the sealing cover contacts the sensor assembly. At the same time, the extrusion plate moves down again under the action of the second hydraulic cylinder to squeeze the sealing cover.

[0018] Preferably, the movable group consists of a first movable plate and a second movable plate, the first movable plate is arranged at the bottom of the assembly ring, the second movable plate is located on a side of the first movable plate away from the assembly ring, one end of the first movable plate is hinged to the assembly ring, and the other end of the first movable plate is hinged to the second movable plate;

[0019] When the assembly ring moves toward the assembly table, it drives the first movable plate and the second movable plate to move. During the movement, the second movable plate first contacts the folding groove. Since the center height of the folding groove is less than the height of the folding groove close to the first conveying pipe, and the height of the folding groove close to the first conveying pipe is less than the height of the folding groove close to the side wall of the assembly cavity, the second movable plate first contacts the section of the folding groove close to the side wall of the assembly cavity and the center of the folding groove, so that the second movable plate is tilted toward the side close to the first conveying pipe under the action of the folding groove; then the second movable plate moves along the folding groove away from the end of the first movable plate, and when the second movable plate moves to the center of the folding groove and the section of the folding groove close to the first conveying pipe, the second movable plate is tilted to the side close to the second conveying pipe. When the assembly ring moves to the maximum stroke, the first movable plate and the second movable plate are close to the folding groove.

[0020] Preferably, a plurality of glue spraying ports are provided on a side of the second movable plate close to the first conveying pipe, and an absorption tank is provided on a side of the second movable plate away from the glue spraying ports. A plurality of cleaning rollers are provided in the absorption tank, and the cleaning rollers are rotatably connected to the absorption tank.

[0021] When the second movable plate moves into position, the glue spray port is facing the edge of the sensor assembly, and the axis of the absorption groove is parallel to the axis of the first conveying pipe. Then, several second movable plates are combined into a support frame above the sensor assembly, and then the sealing cover falls to the top of the support frame through the second conveying pipe, that is, the bottom of the sealing cover contacts with several cleaning rollers, and then the sealing cover rotates under the rotation of the extrusion plate. When the sealing cover rotates, it comes into friction contact with several cleaning rollers, so that the cleaning rollers clean the bottom of the sealing cover and clear the dust at the bottom of the sealing cover, thereby improving the quality of subsequent sealing assembly.

[0022] Preferably, the first movable plate and the second movable plate are both provided with a rubber delivery pipe and a delivery trough, the assembly ring is provided with a rubber storage cavity, the rubber storage cavity is provided with a suction pump, the assembly ring is further provided with an impurity cavity, the impurity cavity is provided with a first air pump;

[0023] The controller controls the suction pump to start, and the suction pump extracts the glue liquid in the glue storage chamber and transports it to the glue delivery pipe through the pipeline. The glue liquid is connected by the telescopic pipe, so that the glue liquid flows smoothly in the glue delivery pipes in the first movable plate and the second movable plate. Then, the glue liquid is transported to the glue spray port through the glue delivery pipe. When the sealing cover is about to be cleaned, the glue liquid is sprayed toward the edge of the sensor assembly through the glue spray port.

[0024] During the cleaning process of the sealing cover, the controller controls the first air pump to start, and the first air pump extracts the gas in the conveying trough. Since the push plate and the push rod of the second hydraulic cylinder are respectively slidably sealed with the first conveying pipe and the second conveying pipe, the absorption trough continuously extracts the air in the assembly cavity. During the extraction process, the dust and impurities cleaned by the cleaning roller are also cleaned, so that the dust and impurities are mixed with air and transported to the conveying trough through the absorption trough, and finally transported to the impurity cavity through the conveying trough.

[0025] Preferably, both ends of the first movable plate are connected to the assembly ring and the second movable plate through telescopic tubes respectively, the glue delivery pipe is connected to the glue spraying port, and the delivery trough is connected to the absorption trough.

[0026] Preferably, a plurality of air suction ports are provided on a side of the assembly platform close to the first delivery pipe, a second air pump is provided inside the assembly platform, the second air pump is connected to the air suction ports via a pipeline, and a flow meter is provided in the pipeline of the second air pump;

[0027] When the sealing cover is squeezed by the squeezing plate again, the controller controls the second air pump to start, and the second air pump extracts air in the assembly table through the air suction port. Then, while the squeezing plate provides pressure, the air suction port also extracts part of the gas in the sealing cover and the sensor assembly. During the extraction process, part of the air will be discharged from the gap between the sealing cover and the sensor assembly. During the discharge process, part of the air will drive the glue between the sealing cover and the sensor assembly to flow, so that the glue completely fills the gap between the sealing cover and the sensor assembly. In addition, the squeezing plate squeezes the sealing cover, which further improves the sealing assembly quality of the sealing cover and the sensor assembly.

[0028] After the extrusion is completed, the second hydraulic cylinder is reset. At this time, the extrusion plate is separated from the surface of the sealing cover. At this time, the air suction port is still performing the extraction operation. During the extraction process, the flow meter converts the air flow signal into an electrical signal and transmits it to the controller. If there is still a large gas flow fluctuation after the extrusion plate is separated, the sensor assembly is not sealed in place, so that the gas in the sensor assembly and the sealing cover is discharged from the gap between the sealing cover and the sensor assembly. If there is no obvious gas flow fluctuation after the extrusion plate is separated, the sensor assembly is sealed in place, thereby completing the inspection of the glue coating quality.

[0029] After completing the self-test, the first hydraulic cylinder drives the push plate to reset, so that the sealed and assembled sensor component returns to the first feed port again, and is finally output to the outside through the first feed port.

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] 1. During assembly, the sealing cover is cleaned and the sensor assembly is sprayed with glue, thereby improving the efficiency of sensor sealing assembly. At the same time, negative pressure is used to discharge the gas in the sealing cover. During the discharge process, the air drives the glue to flow, further allowing the glue to fill the gap between the sealing cover and the sensor assembly, thereby further improving the sealing assembly quality of the sensor assembly.

[0032] 2. After the assembly is completed, continue to use the extracted air to detect the flow fluctuation of the extracted gas, so as to realize the detection of the sealing quality of the sensor assembly and achieve the self-inspection effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0056] Working principle of the present invention:

[0057] The rotating roller rotates under the control of the controller, so that during the rotation of the rotating roller, the sensor assembly and the sealing cover are driven to move along the first feed port 11 and the second feed port 12 respectively. When the sensor assembly moves above the push plate 23, the push rod of the first hydraulic cylinder immediately pushes the push plate 23 to move. The push plate 23 drives the sensor assembly to move along the first conveying pipe 21, so that the push plate 23 conveys the sensor assembly to the assembly table 15.

[0058] When the assembly body 3 is assembled, the controller controls the drive motor to start, and the drive shaft of the drive motor drives the rotating gear 18 to rotate. When the rotating gear 18 rotates, it engages with the rack on the assembly ring 31. Then, the assembly ring 31 moves under the action of the rotating gear 18, and the assembly ring 31 then drives the plurality of movable groups 32 to move toward the side close to the assembly platform 15;

[0059] When the assembly ring 31 moves toward the assembly table 15, it drives the first movable plate 33 and the second movable plate 34 to move. During the movement, the second movable plate 34 first contacts the return groove 16. Since the center height of the return groove 16 is less than the height of the return groove 16 close to the first conveying pipe 21, and the height of the return groove 16 close to the first conveying pipe 21 is less than the height of the return groove 16 close to the side wall of the assembly cavity 13, the second movable plate 34 first contacts the return groove 16 close to the side wall of the assembly cavity 13 and the center of the return groove 16. The second movable plate 34 tilts toward the side close to the first conveying pipe 21 under the action of the return groove 16. Then, the end of the second movable plate 34 away from the first movable plate 33 moves along the return groove 16. When the second movable plate 34 moves to the center of the return groove 16 and the section where the return groove 16 is close to the first conveying pipe 21, the second movable plate 34 tilts toward the side close to the second conveying pipe 22. When the assembly ring 31 moves to the maximum stroke, the first movable plate 33 and the second movable plate 34 are in close contact with the return groove 16.

[0060] When the second movable plate 34 is moved into position, the glue spray port 35 is facing the edge of the sensor assembly, and the axis of the absorption groove 36 is parallel to the axis of the first conveying pipe 21. Then, several second movable plates 34 are combined to form a support frame above the sensor assembly.

[0061] After the sensor assembly moves to the assembly table 15, the sealing cover enters the second conveying pipe 22 through the rotating roller, and then the sealing cover falls along the second conveying pipe 22 to the top of the assembly body 3, that is, the bottom of the sealing cover contacts the plurality of cleaning rollers 37, and then the push rod of the second hydraulic cylinder drives the extrusion plate 24 to move, so that the extrusion plate 24 contacts the sealing cover during the movement, and the rotating motor is started. The driving shaft of the rotating motor drives the extrusion plate 24 to rotate, and the extrusion plate 24 drives the sealing cover to rotate when the extrusion plate 24 rotates. Then, the sealing cover rotates under the rotation of the extrusion plate 24, and when the sealing cover rotates, it comes into friction contact with the plurality of cleaning rollers 37, so that the cleaning rollers 37 clean the bottom of the sealing cover;

[0062] The controller starts the suction pump, which extracts the glue liquid from the glue storage chamber and delivers it to the glue delivery pipe 38 through the pipeline. The glue liquid is connected by the telescopic tube, so that the glue liquid flows smoothly in the glue delivery pipe 38 between the first movable plate 33 and the second movable plate 34. The glue liquid is then delivered to the glue spray port 35 through the glue delivery pipe 38. When the sealing cover is about to be cleaned, the glue liquid is sprayed toward the edge of the sensor assembly through the glue spray port 35.

[0063] During the cleaning process of the sealing cover, the controller controls the first air pump to start, and the first air pump extracts the gas in the delivery groove 39. Since the push plate 23 and the push rod of the second hydraulic cylinder are respectively slidably sealed with the first delivery pipe 21 and the second delivery pipe 22, the absorption groove 36 continuously extracts the air in the assembly chamber 13. During the extraction process, the dust and impurities cleaned by the cleaning roller 37 are also cleaned, so that the dust and impurities are mixed with air and transported to the delivery groove 39 through the absorption groove 36, and finally transported to the impurity chamber through the delivery groove 39.

[0064] When the sealing cover is cleaned and the glue spraying port 35 has finished spraying glue, the assembly body 3 is reset. At this time, the controller controls the driving motor to reverse, and the driving shaft of the driving motor drives the rotating gear 18 to reverse. When the rotating gear 18 rotates, it engages with the rack on the assembly ring 31. Then, the assembly ring 31 moves under the action of the rotating gear 18, and the assembly ring 31 then drives the plurality of movable groups 32 to move to the side away from the assembly platform 15.

[0065] During the resetting process of the assembly ring 31, the plurality of movable groups 32 are driven to reset, and then the support frame formed by the plurality of second movable plates 34 is dismantled, so that the sealing cover loses the support function of the support frame. Subsequently, the sealing cover falls to the spraying area of ​​the glue, so that the sealing cover contacts the sensor assembly. At the same time, the squeezing plate 24 moves downward again under the action of the second hydraulic cylinder to squeeze the sealing cover.

[0066] When the sealing cover is squeezed by the squeezing plate 24 again, the controller controls the second air pump to start, and the second air pump extracts air from the assembly table 15 through the air suction port 19. Then, while the squeezing plate 24 provides pressure, the air suction port 19 also extracts part of the gas in the sealing cover and the sensor assembly. During the extraction process, part of the air will be discharged from the gap between the sealing cover and the sensor assembly. During the discharge process, part of the air will drive the glue between the sealing cover and the sensor assembly to flow, so that the glue completely fills the gap between the sealing cover and the sensor assembly. In addition, the squeezing plate 24 squeezes the sealing cover, which further improves the sealing assembly quality of the sealing cover and the sensor assembly.

[0067] After the extrusion is completed, the second hydraulic cylinder is reset, and the extrusion plate 24 is separated from the surface of the sealing cover. At this time, the air suction port 19 is still performing the extraction operation. During the extraction process, the flow meter converts the air flow signal into an electrical signal and transmits it to the controller. If there is still a large gas flow fluctuation after the extrusion plate 24 is separated, the sensor assembly is not sealed in place, so that the gas in the sensor assembly and the sealing cover is discharged from the gap between the sealing cover and the sensor assembly. If there is no obvious gas flow fluctuation after the extrusion plate 24 is separated, the sensor assembly is sealed in place, thereby completing the inspection of the glue coating quality.

[0068] After completing the self-test, the first hydraulic cylinder drives the push plate 23 to reset, so that the sealed and assembled sensor component returns to the first feed port 11 again, and is finally output to the outside through the first feed port 11.

[0069] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
