Description

Technical Field

[0001] The present invention relates to the technical field of capacitive displacement sensors, in particular to an automatic assembly device for capacitive displacement sensors. Background Art

[0002] The capacitive displacement sensor is composed of a sensor back cover 100, a positioning ring 200, a fixed electrode plate 300, a fixed electrode plate fixing frame 400, a sensor housing 500, a sensor front cover 600 and other structures (such as Figure 1 As shown in the figure, the working principle is that one end of the measuring rod is connected to the moving electrode plate, and the other end is in contact with the object being measured. When the object being measured moves, the measuring rod drives the moving electrode plate to move, and displacement is generated synchronously between the moving electrode plate and the fixed electrode plate, causing the capacitance to change accordingly. By sensing the change in capacitance, the displacement can be measured. Because the front cover of the capacitive displacement sensor needs to be equipped with a positioning block, it has an additional thread compared to the rear end cover. The positioning rings and fixed electrode plates on the left and right ends are completely symmetrical in design. The fixed electrode plate and the fixing bracket use a clearance fit, making assembly relatively simple. The positioning ring uses an interference fit, and its assembly process requires the design of a dedicated stamping structure. The fixing bracket is located at the innermost part of the sensor and is used to fix the two fixed electrode plates. The threads on the left and right ends of the housing are asymmetrical. The structure of the right end cover is longer, so the corresponding threads are also longer than those on the left. The housing connects the front and rear end covers and protects the internal structure of the sensor.

[0003] A capacitive displacement sensor is a type of displacement sensor. Its detection principle is to change the distance between the two plates of a capacitor through displacement, converting the displacement into a change in capacitance for measurement. It offers many advantages, including low power consumption, high impedance, excellent dynamic characteristics, and non-contact measurement. It is widely used in aerospace engines and ultra-precision machining. Currently, the assembly of capacitive displacement sensors is mainly manual, which is not only inefficient but also affects assembly accuracy. Therefore, an automatic assembly device for capacitive displacement sensors has been invented. Summary of the Invention

DETAILED DESCRIPTION

[0016] To make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0017] The present invention provides an automatic assembly device for capacitive displacement sensors. Figures 1-6, including a table body, two groups of step loading modules are provided on the left side of the top of the table body, a magazine loading module is provided on the rear side of the top of the table body on the right side of the step loading module, an assembly module is provided on the top of the table body in front of the magazine loading module, an industrial robot 50 is provided on the top of the table body on the right side between the magazine loading module and the assembly module, a tooling fixture module is provided on the top of the table body in front of the industrial robot 50, and a flat warehouse 40 with a plurality of circular grooves formed thereon is fixedly installed on the top of the table body on the right side of the industrial robot 50. The step loading module, magazine loading module, assembly module, industrial robot 50 and tooling fixture module are all electrically connected to the programmable logic controller.

[0018] Among them: the flat warehouse 40 serves as a storage mechanism for the front and rear end covers. Each flat warehouse 40 has 9 circular grooves, which can accommodate nine end covers and can also be positioned. The diameter of the circular groove is 29 mm, forming a clearance fit with the end cover. The clearance fit can achieve more accurate positioning of the end cover and allow the industrial robot to smoothly clamp it.

[0019] The step loading module includes: a loading machine housing 10, a cylinder base 11, a first pushing cylinder 12, a support plate 13, a movable plate 14, a fixed plate 15, a first silo 16, and a silo partition 17; The loader housing 10 is fixedly mounted on the top of the table body, the cylinder base 11 is fixedly mounted on the top of the inner cavity of the loader housing 10, the pushing cylinder 12 is fixedly mounted on the cylinder base 11, and the piston rod of the pushing cylinder 12 is fixedly mounted on the support plate 13, and a number of movable plates 14 are fixedly mounted on the top of the support plate 13. The inner cavity of the loader housing 10 is fixedly mounted with a number of fixed plates 15, and the fixed plates 15 and the movable plates 14 are arranged alternately, specifically, the fixed plates 15 and the movable plates 14 are connected by slide rails, the first hopper 16 is fixedly mounted in the loader housing 10, and the first hopper 16 is located on one side of the fixed plate 15, and the hopper partition 17 is fixedly mounted on the top of the first hopper 16.

[0020] Among them: the loader housing 10 is composed of two side panels, the side panels are connected to an aluminum plate inclined at 15° to form a first hopper 16, the area of ​​the first hopper 16 is 37 cm2, and it can accommodate about 15 shells or 15 fixing frames and 25 fixed plates at a time; the fixed plate 15 can not only load materials, but also form a part of the loader housing 10 by being fixedly connected with the two side panels; the movable plate 14 and the fixed plate 15 cooperate as the core of the step loading module, which plays the role of loading and orienting the materials.

[0021] The working principle of the step loading module is differentiated according to the diameter of the material. The radius range of the material is 9 to 14.5 mm, and the width of the movable plate 14 is 20 mm. Since the movable plate 14 and the fixed plate 15 are connected by a slide rail, a 2 mm gap is left in the middle to reduce friction. The width of the fixed plate 15 is 19 mm, and the length of the movable plate 14 is 200 mm. Theoretically, each loading can accommodate one fixed frame and three fixed plates at the same time. The fixed plate 15 must be connected to the loader housing 10 and has a width of 210 mm. In order for the material to slide smoothly to the fixed plate 15, the angle between the step loading module and the horizontal ground is 45°, and the angle between the first hopper 16 and the horizontal ground is 15°.

[0022] When the stepped loading module is working, the first pushing cylinder 12 retracts first, and a part of the material slides onto the first movable plate 14 by free fall. At this time, the first pushing cylinder 12 drives the movable plate 14 to extend, and the material is sorted for the first time during this period (sorting means placing the material horizontally). Then it retracts again, and the material slides to the second movable plate 14. The stepped loading module will sort the material three times. At this time, all the materials are placed horizontally. The last extension of the first pushing cylinder 12 will push the material to the conveying component to realize the loading of the fixed frame and the shell.

[0023] A conveying assembly is provided on the right side of the loader housing 10; The conveying assembly includes: a belt conveyor 20, a material baffle 21, a second pushing cylinder 22, an optical fiber sensor 23, an inductive sensor 24, and a material slide rail 25; The belt conveyor 20 is arranged on the top right side of the loader housing 10. A material baffle 21 is provided on one side of the top of the belt conveyor 20. The second pushing cylinder 22 is fixedly installed on the left side of the opposite ends of the two groups of belt conveyors 20. A material slide rail 25 is fixedly installed on the belt conveyor 20 on the right side of the second pushing cylinder 22. An optical fiber sensor 23 is fixedly installed on the belt conveyor 20 on one side of the second pushing cylinder 22. An inductive sensor 24 is fixedly installed on the belt conveyor 20 on one side of the second pushing cylinder 22.

[0024] Among them: After the stepped loading module pushes out the cylindrical material, it is necessary to use a conveying component to transport the material to the fixture module and distinguish and position it, so that the industrial robot can accurately transport the material for assembly. When the belt conveyor 20 transports the material, its second pushing cylinder 22 can cooperate with the optical fiber sensor 23 and the inductive sensor 24 to achieve material differentiation. In addition, the maximum diameter of the three materials is 29mm, the bandwidth is 30mm, the conveyor belt of the belt conveyor 20 is 379mm long, and a maximum of four shells can be transported on the conveyor belt at the same time. The conveyor belt at the fixed frame and the fixed electrode plate is 474mm long, and a maximum of four fixed frames and five fixed electrodes can be transported at the same time.

[0025] The magazine loading module includes: a reduction motor 31, a material brush 32, a second hopper 33 with a second through hole at its bottom end, a frame 34 with a first through hole at its top end, a slide 35 with a circular countersunk hole, a first slide cylinder 36, and a bottom plate 37; The base plate 37 is fixedly mounted on the top of the table body, the frame 34 is fixedly mounted on the top of the base plate 37, the first slide cylinder 36 is fixedly mounted on the inner cavity of the frame 34, the slide 35 is slidably connected to the first slide cylinder 36, the second silo 33 is fixedly mounted on the top of the frame 34, the reduction motor 31 is fixedly mounted on the top of the second silo 33, the output shaft of the reduction motor 31 passes through the second silo 33 to fix the material brush 32, and the material brush 32 is located in the second silo 33.

[0026] The thickness of the positioning ring is 5.5mm and the maximum diameter is 19.5mm. It is placed on both ends of the fixing frame and can play the role of positioning the electrode plate after being glued. The present invention uses a clip loading module to store and load the positioning ring.

[0027] The inner diameter of the second silo 33 is 170mm. In order to facilitate intuitive observation of the amount of material in the silo, the second silo 33 is made of PC. There is a brush structure inside the second silo 33, and its effective depth is about 87.5mm, which means that theoretically it can accommodate more than 1,200 positioning rings at one time. There is a through hole at the bottom of the second silo 33 with a diameter of 19.5mm and a depth of 14mm. Combined with the gap with the first slide cylinder 36, it can just accommodate three positioning rings. During operation, the output shaft of the reduction motor 31 is connected to the material brush 32 through a flat key, so that the material brush 32 can rotate synchronously with the reduction motor. The slowly rotating material brush 32 will sweep the positioning rings in the silo into the through hole and arrange them in sequence. The slide 35 at the top of the first slide cylinder 36 is provided with a circular countersunk hole with a diameter consistent with that of the positioning ring and a depth of 2.5 mm. When the first slide cylinder 36 is retracted, it becomes coaxial with the through hole of the second hopper 33. At this time, the positioning ring will perform free fall and fall into the circular countersunk hole. The distance between the slide 35 and the top of the frame 34 is 3.5 mm. Combined with the circular countersunk hole on the slide 35, the depth reaches 6 mm, which can only accommodate one positioning ring.

[0028] The fixture module includes: a clamping table 51, a clamping jaw, a dispensing simulation pen tip, and an end cap clamping jaw; The clamping platform 51 is fixedly installed on the top of the table body. A clamping claw is provided on the left side of the top of the clamping platform 51, a dispensing simulation pen tip is provided in the middle of the top of the clamping platform 51, and an end cover clamping claw is provided on the right side of the top of the clamping platform 51.

[0029] The assembly module includes: a guide rod cylinder 521, a stamping die 522, a conical mandrel 523, a second slide cylinder 524, a frame 525, a double-axis cylinder 526, and a V-shaped block 527 with a semicircular hole on its top; The frame 525 is fixedly mounted on the top of the table body, and the guide rod cylinder 521 is fixedly mounted on the top of the U-shaped plate on the right side of the frame 525, and the piston rod of the guide rod cylinder 521 is fixedly mounted on the stamping die 522. The second slide cylinder 524 is fixedly mounted on the top of the frame 525 directly below the stamping die 522, and the slide on the second slide cylinder 524 is fixedly mounted on the conical mandrel 523. The dual-axis cylinder 526 is fixedly mounted on the top left side of the frame 525, and the piston rod of the dual-axis cylinder 526 is fixedly mounted on a block with a semicircular hole in the middle thereof. The V-block 527 is fixedly mounted on the top left side of the frame 525, and the block and the V-block 527 are in contact with each other.

[0030] The dual-axis cylinder 526 and the V-block 527 form a fixture for the outer shell, fully positioning it. To avoid interfering with the industrial robot's material placement, the stroke of the dual-axis cylinder 526 is 60mm. The second slide cylinder 524, in conjunction with the conical mandrel 523, forms a fixture for the fixed frame. The second slide cylinder 524 has a stroke of 75mm and is connected to a conical mandrel 523 at the top for positioning the fixed frame. When the second slide cylinder 524 retracts, the stamping die 522 connected to the bottom of the guide rod cylinder 521 becomes coaxial with the conical mandrel 523.

[0031] During specific use, the operating steps of those skilled in the art are as follows: During assembly, the second slide cylinder 524 extends, and after the fixing frame is assembled, the industrial robot 50 picks up the fixed electrode plate from the step loading module and directly assembles it on the fixing frame; After the fixed electrode plate is assembled, the locating ring needs to be assembled. At this point, the magazine loading module has already delivered a locating ring to the second through-hole. The industrial robot 50 first places the locating ring on the fixed frame, but the locating ring and the fixed frame have an interference fit, so the industrial robot 50 cannot assemble the locating ring in one step. At this time, the second slide cylinder 524 will retract and send a signal to the programmable logic controller. After receiving the signal, the guide rod cylinder 521 is controlled to extend with a stroke of 40mm, completing the final reinforcement of the locating ring. After the work is completed, the guide rod cylinder 521 retracts and the second slide cylinder 524 extends. The industrial robot 50 replaces the gripper with a dispensing simulation pen tip to simulate the dispensing process of the locating ring. The dispensing simulation pen tip is then replaced with a gripper, and the half-assembled fixed frame is clamped and flipped 180°. The previous assembly process is repeated to complete the assembly of the fixed electrode plate and the locating ring at the other end. Stamping process and assembled parts.

[0032] After the mounting bracket is assembled, it needs to be placed inside the housing. The industrial robot 50 moves to the stepped loading module, clamps it onto the V-block 527, and places it. At this point, the programmable logic controller extends the dual-axis cylinder 526 to clamp the housing through the cooperation of the block and the V-block 527, limiting its z-axis rotational freedom. After the housing is clamped, the industrial robot 50 moves the mounting bracket to the housing for assembly. The clamping jaws are then replaced and the end cap is clamped to the flat storage 40. The end cap is tightened on the housing, and the housing is flipped 180° before repeating the process. Once the cap is tightened, assembly is complete.

In particular, as long as there are no structural conflicts, the various features of the embodiments disclosed herein may be combined with each other in any manner, and the omission of an exhaustive description of such combinations in this specification is solely for the sake of space and resource conservation.
