[0002] A pressure sensor is a device that can convert a pressure signal into an electrical signal. When assembling a pressure sensor, after placing an inductive element in a housing, glue is injected into the housing to fix and encapsulate the internal components of the housing. In the existing documents, the sensor glue injection robot consists of an upper cover mechanism and a lifting mechanism. The upper cover mechanism includes a sealing plate, a sealing frame, and a bracket. An air pipeline is provided inside the sealing frame and is connected to a vacuum generating device. The lifting mechanism includes a cylinder plate, a positioning plate, a support, a connecting block, a positioning pin, a positioning diamond pin, a stop block, a linear bearing, a sliding column, and a cylinder, which are used to precisely control the glue injection process, assemble the pressure sensor, connect the connecting wires, place the sensor in an injection mold, close the mold, perform glue injection operations through a glue injection head at the opening of the metal housing, and take out the sensor after the mold is opened when the glue is full. Based on the retrieval of the above patents and the discovery of equipment in the prior art, for the existing sensor assembly robots, when assembling pressure sensors, glue injection and shaping and encapsulation are required. The existing glue injection structures of robots often result in unstable glue injection amounts due to insufficient or uneven injection pressure, which affects product quality. During the glue injection process, glue waste is easily caused due to inaccurate control of the glue injection amount. After glue injection, glue is easily left at the bottom of the injection head, which is difficult to clean and easily blocked. Summary of the Invention

Specific embodiments

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0018] Please refer to Figure 1 , Figures 5 - 8 As shown in the figure, the present invention is a sensor automatic assembly robot, including a robot bracket 1. A drive motor is installed on the top side of the robot bracket 1. A drive shaft 2 is installed on the output shaft of the drive motor. A loading tray 5 is installed on the drive shaft 2. A storage tank 4 is provided on the loading tray 5. The assembled sensor body 6 is placed in the storage tank 4; An industrial robot fuselage 8 is installed on the robot bracket 1. A mounting bracket 11 is installed on the industrial robot fuselage 8. An injection head 10 is vertically installed inside the mounting bracket 11; When assembling the pressure sensor, after placing the inductance element in the housing, the housing is fixed and encapsulated by injecting glue into the housing. When performing the encapsulation, the housing filled with the inductance element is placed in the storage tank 4. Under the drive cooperation of the drive motor and with the cooperation of the drive shaft 2, the loading tray 5 is driven to rotate, which can realize the transportation of the sensor body 6. The sensor body 6 is transported to directly below the injection head 10, and the injection of the glue material is realized through the injection head 10, so as to realize the encapsulation operation of the sensor; At the top of the industrial robot body 8, a transfer structure 9 and a driving tooth plate 13 are installed. The transfer structure 9 is used for the pressurized transportation of canned rubber material. The transfer structure 9 includes a transfer cylinder 91. The transfer cylinder 91 is installed on the top side of the industrial robot body 8. A slide rail 93 is fixed on the inner wall of the middle part of the transfer cylinder 91. One side of the positioning plate 96 is fixed with a limiting rod 95. A slide rail 93 is arranged inside the pushing piston 92. A rod hole is opened in the slide rail 93. One end of the limiting rod 95 is inserted into the rod hole of the slide rail 93. A second spring 94 is fixedly connected between the slide rail 93 and the positioning plate 96. The second spring 94 is sleeved on the limiting rod 95. The positioning plate 96 is provided with a mounting hole. A pull rod 99 is inserted into the mounting hole. One end of the pull rod 99 is fixed with a pushing piston 92. A chute is arranged inside the slide rail 93. A notch is arranged on the side of the pushing piston 92. The notch of the pushing piston 92 corresponds to the chute of the slide rail 93. A transfer motor 97 is installed on the top side of the industrial robot body 8. A driving disc 98 is installed on the output shaft of the transfer motor 97. A connecting rod 910 is connected to the eccentric position of the driving disc 98. One end of the connecting rod 910 is connected to one end of the pull rod 99. One end side wall of the transfer cylinder 91 is provided with a feed inlet. A diversion pipe 22 is connected to the feed inlet. The diversion pipe 22 is connected to the bottom of the storage hopper 21. The slide rail 93 slides horizontally to the inside of the feed inlet.

[0019] When injecting material into the sensor body 6, in order to ensure the stability and accuracy of the injection volume, the injection operation is carried out through the transfer structure 9. During the injection, through the operation of the transfer motor 97, the driving disc 98 is driven to operate. With the cooperation of the connecting rod 910, the pulling and pushing of the pull rod 99 can be realized. With the cooperation of the pulling and pushing, the pushing piston 92 can be driven to move. When the pushing piston 92 moves, the cavity space near the one-way valve 14 gradually becomes larger. Since the space in the cavity on one side of the pushing piston 92 becomes larger and no gas enters, the pressure in the cavity on one side of the rotating disc 19 becomes smaller. When the pushing piston 92 slides along the chute position of the slide rail 93, the position of the slide rail 93 does not change, and the slide rail 93 temporarily blocks the feed inlet of the diversion pipe 22. When the pushing piston 92 moves to the end of the chute on the slide rail 93, with the pulling cooperation of the pushing piston 92, the slide rail 93 can be pushed along the limiting rod 95, so that the slide rail 93 is misaligned with the feed inlet. Since the pressure in the cavity on one side of the pushing piston 92 is relatively small, when the feed inlet is opened instantaneously, the rubber material in the driving tooth plate 13 is quickly sucked into the cavity inside one side of the pushing piston 92 through the diversion pipe 22. During the subsequent rotation of the drive disk 98, the connecting rod 910 can cooperate to push the pull rod 99. When the pull rod 99 is pushed in the reverse direction, under the rebound effect of the second spring 94, the slide rail 93 can block the feed port. During the continuous pushing process of the push piston 92, the rubber material sucked into the cavity on one side of the push piston 92 can be pushed out through the connecting pipe 15. The rubber material can be injected into the sensor body 6 through the injection head 10, which can achieve the pressurized discharge of the colloid, avoid pipeline blockage during colloid injection, and at the same time can quantitatively inject glue, avoid waste of rubber material, and improve the utilization rate of rubber material.

[0020] Please refer to Figure 4 As shown, the other end of the transfer cylinder 91 is connected to a connecting pipe 15. A one-way valve 14 is installed at the top of the connecting pipe 15. The bottom end of the connecting pipe 15 is connected to the injection head 10. The one-way valve 14 acts on the connecting pipe 15, which can prevent the rubber material in the connecting pipe 15 from flowing back. At the same time, through pressurized ejection, it is convenient for subsequent pipeline cleaning.

[0021] A support frame 3 is installed on the top side of the robot bracket 1. A bearing is installed on the support frame 3. The feeding tray 5 is connected to the outer circle of the bearing, and the support frame 3 is connected to the inner circle of the bearing.

[0022] Please refer to Figures 2 - 3 As shown, drive tooth plates 13 are intermittently fixed on the circumferential outer side of the feeding tray 5. A rotating shaft 25 is vertically installed on the middle cross plate of the industrial robot body 8. A drive gear 26 is installed at the bottom end of the rotating shaft 25. A first bevel gear 24 is installed at the top end of the rotating shaft 25. A mounting shaft is horizontally installed on the middle vertical plate of the industrial robot body 8. A second bevel gear 23 is fixed at one end of the mounting shaft. The second bevel gear 23 and the first bevel gear 24 are meshed with each other at a right angle. The drive gear 26 and the drive tooth plate 13 are meshed with each other. The other end of the horizontally installed shaft is fixed with a rotating disk 19. Scrapers 16 are intermittently fixed on the rotating disk 19. The inner wall of the scraper 16 is located at the bottom port of the injection head 10 after rotation.

[0023] A collection box 18 is suspended from the bottom side of the mounting frame 11. A cleaning blade 17 is installed above the collection box 18. The cutting edge of the cleaning blade 17 is attached to the inner side of the scraper 16. During operation, to avoid waste of the rubber compound and ensure the cleanliness of the rubber head of the injection head 10, when injecting glue, when the driving motor drives the driving shaft 2 to rotate, it drives the sensor body 6 to feed materials. When the feeding tray 5 rotates, it can drive the driving gear 26 to rotate under the cooperation of the driving tooth plate 13. Under the rotation of the driving gear 26, the first bevel gear 24 is driven to rotate by the rotating shaft 25. Under the cooperation of the second bevel gear 23, the mounting shaft can be driven to move, driving the rotating disk 19 to rotate. After injecting glue through the injection head 10, when the rotating disk 19 rotates, the rubber head at the bottom of the injection head 10 after injection can be scraped and cleaned by the scraper 16, which can clean the bottom of the injection head 10, avoid the rubber compound from solidifying and sticking to the bottom of the injection head 10 to cause blockage, and ensure the smoothness of glue injection; After cleaning the bottom port of the injection head 10 by the scraper 16, during the continuous rotation of the scraper 16, the rubber compound on the inner wall of the scraper 16 is cleaned by the cleaning blade 17, which can ensure that when the cleaning blade 17 rotates, the bottom of the injection head 10 can be continuously cleaned. The waste materials cleaned fall freely into the collection box 18 through the gap between the two scrapers 16, which can ensure the continuous and effective cleaning of the bottom of the injection head 10 and ensure the canning effect.

[0024] Please refer to Figure 9 As shown, a limiting structure 7 is installed on the outside of the mounting frame 11. The limiting structure 7 includes a connecting plate 71, which is fixed on the outside of the mounting frame 11. A sliding hole is vertically opened inside the connecting plate 71. A positioning hole is provided on one side of the sliding hole. A sliding rod 77 slides vertically in the sliding hole. A limiting strip 74 is fixed on one side of the sliding rod 77, and the limiting strip 74 is arranged in the positioning hole. A rubber cap 76 is fixed at the bottom end of the sliding rod 77, and an electrode cap 72 is fixed at the top end of the sliding rod 77. A first spring 75 is fixedly connected between the connecting plate 71 and the rubber cap 76. The limiting structure 7 further includes an electrode dial 73, and the electrode cap 72 is in sliding contact with the electrode dial 73. A warning light is arranged on one side of the mounting frame 11, and the electrode cap 72, the electrode dial 73, the warning light and the power supply are connected; When injecting glue, in order to ensure the stable glue injection state of the sensor body 6 and to achieve accurate glue injection, when the sensor body 6 is conveyed by the rotation of the loading tray 5, the sensor body 6 being conveyed enters below the limit structure 7. When the sensor body 6 enters below the rubber cap 76, it can lift the rubber cap 76 and compress the first spring 75. After the rubber cap 76 is lifted, with the cooperation of the sliding rod 77, the electrode cap 72 can be brought into contact with the electrode dial 73. After the electrode cap 72 contacts the electrode dial 73, the warning light can be powered on. After the power-on signal of the warning light is powered on and received by the control panel 12, the control panel 12 can control the driving disk 98 to operate again to achieve the glue injection operation; When the sensor body 6 on the loading tray 5 is missing, the rubber cap 76 will not be subjected to the lifting force and will not trigger the warning light, and there is no need to perform the glue injection operation. It can accurately inject glue into the sensor body 6 to ensure the accuracy of glue injection, avoid waste at the same time, and at the same time, through the reverse pressing of the rubber cap 76, the posture of the circular sensor body 6 can be corrected to ensure that after glue injection, the glue is evenly spread in the sensor body 6 to achieve the plastic sealing of the sensor.

[0025] Please refer to Figure 2 、 Figure 6 As shown, a control panel 12 is installed on one side of the industrial robot body 8. The control panel 12 is used for starting and stopping control of the driving motor and the driving disk 98, and the control panel 12 is used for receiving signals of the warning light.

[0026] Working principle: When assembling the pressure sensor, after placing the inductive element in the housing, glue is injected into the housing to fix and encapsulate the internal components of the housing. During encapsulation, the housing filled with the inductive element is placed in the storage tank 4. Under the driving cooperation of the driving motor and with the cooperation of the driving shaft 2, the loading tray 5 is driven to rotate, which can convey the sensor body 6 and convey the sensor body 6 directly below the injection head 10. Through the injection head 10, glue is injected to achieve the encapsulation operation of the sensor; When injecting material into the sensor body 6, in order to ensure the stability and accuracy of the injection volume, the injection operation is carried out through the transfer structure 9; When injecting material, the transfer motor 97 operates to drive the driving disk 98 to operate. With the cooperation of the connecting rod 910, the pull rod 99 can be pulled and drawn. With the pull and draw, the push piston 92 can be driven to move. When the push piston 92 moves, the cavity space near one end of the one-way valve 14 gradually becomes larger. Since the space in the cavity on one side of the push piston 92 becomes larger and no gas enters, the pressure in the cavity on one side of the rotating disk 19 becomes smaller; When the pushing piston 92 slides along the chute position on the slide rail 93, the position of the slide rail 93 remains unchanged, and the slide rail 93 temporarily seals the feed port of the diversion pipe 22; When the pushing piston 92 moves to the end of the chute on the slide rail 93, under the pulling cooperation of the pushing piston 92, the slide rail 93 can be pushed along the limit rod 95, so that the slide rail 93 is misaligned with the feed port. Since the pressure in the cavity on one side of the pushing piston 92 is relatively small, when the feed port is opened instantaneously, the rubber material in the driving gear plate 13 is quickly sucked into the cavity on one side of the pushing piston 92 through the diversion pipe 22; During the subsequent rotation of the driving disc 98, with the cooperation of the connecting rod 910, the pull rod 99 can be pushed. When the pull rod 99 is pushed in the reverse direction, under the rebound effect of the second spring 94, the slide rail 93 seals the feed port. During the continuous pushing process of the pushing piston 92, the rubber material sucked into the cavity on one side of the pushing piston 92 can be pushed out through the connecting pipe 15, and the rubber material can be injected into the sensor body 6 through the injection head 10, which can realize the pressurized discharge of the colloid, avoid pipeline blockage during colloid injection, and at the same time can quantitatively inject the glue, avoid waste of the rubber material, and improve the utilization rate of the rubber material.

[0027] The other end of the transfer cylinder 91 is connected with a connecting pipe 15. A one-way valve 14 is installed at the top end of the connecting pipe 15, and the bottom end of the connecting pipe 15 is connected with the injection head 10. The one-way valve 14 acts on the connecting pipe 15, which can prevent the rubber material in the connecting pipe 15 from flowing back, and at the same time, through pressurized pushing, it is convenient for subsequent pipeline cleaning; In order to avoid waste of the rubber material and ensure the cleanliness of the rubber head of the injection head 10, when injecting glue, when the driving motor drives the driving shaft 2 to rotate, the sensor body 6 is driven for feeding. When the feeding tray 5 rotates, with the cooperation of the driving gear plate 13, the driving gear 26 can be driven to rotate. With the rotation of the driving gear 26, the first bevel gear 24 is driven to rotate through the rotating shaft 25. With the cooperation of the second bevel gear 23, the installation shaft can be driven to move, driving the rotating disc 19 to rotate. After injecting glue through the injection head 10, when the rotating disc 19 rotates, the rubber head at the bottom of the injection head 10 after injecting glue can be scraped and cleaned by the scraper 16, which can clean the bottom of the injection head 10, avoid the rubber material from solidifying and sticking to the bottom end of the injection head 10, causing blockage, and ensure the smoothness of glue injection; After the bottom port of the injection head 10 is cleaned by the scraper 16, during the continuous rotation of the scraper 16, the rubber material on the inner wall of the scraper 16 is cleaned by the cleaning blade 17, which can ensure that when the cleaning blade 17 rotates, it can continuously clean the bottom of the injection head 10. The waste materials cleaned fall freely into the collection box 18 through the gap between the two scrapers 16, which can ensure the continuous and effective cleaning of the bottom of the injection head 10 and ensure the canning effect; When injecting glue, to ensure the stable glue injection state of the sensor body 6 and to achieve accurate glue injection, when the sensor body 6 is conveyed by the rotation of the loading tray 5, the sensor body 6 being conveyed enters below the limiting structure 7. When the sensor body 6 enters below the rubber cap 76, the rubber cap 76 can be lifted, and the first spring 75 can be compressed. After the rubber cap 76 is lifted, with the cooperation of the sliding rod 77, the electrode cap 72 can be brought into contact with the electrode paddle 73. After the electrode cap 72 contacts the electrode paddle 73, the warning light can be powered on. After the power-on signal of the warning light is powered on and received by the control panel 12, the control panel 12 can control the driving disk 98 to operate again to achieve the glue injection operation; When the sensor body 6 on the loading tray 5 is missing, the rubber cap 76 will not be subjected to a lifting force, the warning light will not be triggered, and there is no need to perform the glue injection operation. Glue can be accurately injected into the sensor body 6 to ensure the accuracy of glue injection and avoid waste at the same time. At the same time, through the reverse pressing of the rubber cap 76, the posture of the circular sensor body 6 can be corrected, ensuring that after glue injection, the glue material is evenly spread in the sensor body 6 to achieve the plastic sealing of the sensor.
