Description

Technical Field

[0001] The present invention relates to the technical field of automation equipment, and more specifically, to an assembly production line for an oil pump motor. Background Art

[0002] The oil pump motor is a specific motor used to drive the oil pump. With the development of automation equipment, the joints of industrial robots and manipulators may need to be equipped with miniaturized hydraulic systems, thus creating a demand for micro oil pump motors in the industry.

[0003] What makes a micro oil pump motor different from a traditional motor is that its size is often only the size of an adult's palm. Under the extreme miniaturization, its own assembly and installation face great difficulties. Conventional manual assembly and installation are no longer possible, and existing assembly equipment often requires a large amount of manpower to assist. The labor cost is high, the efficiency is low, and it is difficult to meet the assembly precision requirements of the product.

[0004] Therefore, a new technical solution is urgently needed to solve the above technical problems. Summary of the invention

[0005] In view of the deficiencies in the prior art, an object of the present invention is to provide an assembly production line for an oil pump motor.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions: an assembly production line for an oil pump motor, comprising a magnetic sheet assembly device, an end cover pre-treatment device and an end cover assembly device;

[0007] The magnetic sheet assembly device comprises a magnetic sheet assembly platform and a rotating disk arranged on the surface of the magnetic sheet assembly platform, the rotating disk is provided with a plurality of positioning fixtures at equal angles, the surface of the assembly platform is provided with a six-axis manipulator, a dispensing mechanism, an image sensor, a magnetic sheet feeding mechanism and a height detection mechanism in sequence around the rotating disk, and also comprises a feeding and conveying mechanism arranged on the surface of the assembly platform on one side of the rotating disk;

[0008] The end cap pre-processing device comprises a pre-processing workbench and an end cap feeding mechanism, a substrate feeding mechanism, a laser engraving mechanism, a flipping and transporting mechanism and a substrate pressing mechanism arranged on the pre-processing workbench;

[0009] The end cap assembly device comprises an assembly workbench and an end cap conveying mechanism, a main body conveying mechanism, a pre-assembly mechanism, a five-axis translation manipulator, a horizontal riveting mechanism and a vertical riveting mechanism arranged on the surface of the assembly workbench;

[0010] It also includes a program burning and sealing device, which includes a burning assembly platform and a burning feeding mechanism, a program burning mechanism, a burning interface gluing mechanism, a gluing cover transfer mechanism, a burning interface cover mechanism, a burning discharging mechanism, and a burning conveying mechanism.

[0011] By adopting the above technical solution, when the present application is working normally, the six-axis manipulator grabs the oil pump motor to be assembled with the magnetic sheet and places it on an empty positioning fixture. After the placement is completed, the rotating disk rotates the rated angle to transport the oil pump motor on multiple positioning fixtures forward one station. After the angle rotation is completed, the dispensing mechanism applies anaerobic glue to the end face of the motor output shaft. At the same time, the magnetic sheet feeding mechanism places and presses the magnetic sheet on the end face of the motor output shaft. At the same time, the six-axis manipulator removes the oil pump motor and places it on the feeding and conveying mechanism and conveys it to the assembly end cover assembly device;

[0012] Workers place the power supply end cap and substrate on the manual end cap loading seat and the manual substrate loading seat respectively; the end cap loading clamping and conveying assembly delivers the end cap to the laser engraving mechanism, and after the laser engraving mechanism completes the engraving of the identification QR code, the flipping and conveying mechanism flips the power supply end cap to face the opening downward and delivers it to the substrate pressing mechanism. At the same time, the substrate loading and sucking assembly delivers the substrate to the substrate pressing mechanism; when the power supply end cap and the substrate are in place, the substrate pressing mechanism completes the crimping assembly of the two; the power supply end cap with the substrate installed is delivered to the end cap assembly device by the flipping and conveying mechanism;

[0013] The end cover conveying mechanism and the main body conveying mechanism respectively send the power supply end cover and the motor main body into the pre-installation mechanism. After the pre-clamping of the two is completed by the pre-installation mechanism, the five-axis translation manipulator sends the pre-installed power supply end cover and motor main body into the horizontal riveting mechanism. After the horizontal riveting mechanism completes the inward bending of the riveted deformed plate, the five-axis translation manipulator sends the water-riveted power supply end cover and motor main body into the vertical riveting mechanism. After the vertical riveting mechanism completes the downward bending of the horizontal section of the riveted deformed plate, the five-axis translation manipulator sends out the assembled oil pump motor.

[0077] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0078] The same parts are denoted by the same reference numerals. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the drawings, and the words "bottom" and "top", "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0079] An assembly production line for an oil pump motor comprises a magnetic sheet assembly device, an end cover pre-processing device, an end cover assembly device and a program burning and sealing device.

[0080] like Figure 1 , Figure 2 and Figure 3 As shown, the magnetic sheet assembly device includes a magnetic sheet assembly platform 1, which is provided with a rotating disk 1-11, and a plurality of positioning fixtures 1-12 are installed at equal angles on the rotating disk 1-11; a six-axis manipulator 1-2, a dispensing mechanism, an image sensor 1-4, a magnetic sheet feeding mechanism and a height detection mechanism are sequentially arranged around the rotating disk 1-11; the magnetic sheet assembly platform 1 is provided with a feeding and conveying mechanism, and a plurality of conveying fixtures 1-71 are arranged at equal intervals on the feeding and conveying mechanism, and each conveying fixture 1-71 is provided with a pressure maintaining component 1-72, and the magnetic sheet assembly platform 1 is provided with a pressure unlocking mechanism at the starting end and the end end of the feeding and conveying mechanism.

[0081] When the present application is working normally, the six-axis manipulator 1-2 grabs the oil pump motor with the magnetic sheet to be assembled and places it on an empty positioning fixture 1-12; after the placement is completed, the rotating disk 1-11 rotates the rated angle to synchronously transport the oil pump motors on multiple positioning fixtures 1-12 forward one workstation.

[0082] After the angle rotation is completed, the dispensing mechanism applies anaerobic glue to the end face of the motor output shaft.

[0083] At the same time, image sensors 1-4 (Keyence IV-150 image recognition sensor can be selected) take pictures of the output shaft end face after glue dispensing, and send the picture electrical signal to the computer, which completes the image comparison.

[0084] At the same time, the magnetic sheet feeding mechanism places and presses the magnetic sheet onto the end face of the motor output shaft (if the glue coating of the previous oil pump motor detected by the image sensor 1-4 is abnormal, the magnetic sheet feeding mechanism will not work).

[0085] At the same time, the height detection mechanism detects the relative height between the upper end surface of the magnetic sheet and the selected end surface of the oil pump motor (if the magnetic sheet feeding mechanism has not installed the magnetic sheet on the previous oil pump motor, the height detection mechanism will not work).

[0086] At the same time, the oil pump motor is removed by the six-axis robot 1-2. The removed oil pump motor has three placement points. If there is no abnormality in the height detection, it is placed on the conveying fixture 1-71. If there is an abnormality in the height detection, it is placed in the defective product position A. If there is an abnormality in the dispensing, it is placed in the defective product position B.

[0087] The conveying jig 1-71 at the initial end of the feed conveying mechanism has the pressure holding component restricted by the pressure unlocking mechanism, forcing it to be in a loosened state to avoid interference with the placement of the oil pump motor. When the six-axis manipulator 1-2 places the oil pump motor that has completed the magnetic sheet assembly and inspection on the conveying jig 1-71, the pressure unlocking mechanism releases the restriction on the pressure holding component 1-72, and the pressure holding component 1-72 presses the magnetic sheet; the conveying jig 1-71 that is sent to the end of the feed conveying mechanism has the pressure holding component 1-72 controlled by the pressure unlocking mechanism to be loosened, ensuring that the oil pump motor is smoothly removed.

[0088] To summarize, the present application realizes the automated assembly of magnetic sheets by cooperating with the glue dispensing mechanism and the magnetic sheet feeding mechanism, and utilizes the image sensors 1-4 and the height detection mechanism to ensure the installation of the magnetic sheets and the reliability of the gluing, thereby effectively preventing the occurrence of the problem of missing magnetic sheets. After the installation of the magnetic sheets is completed, the oil pump motor is sent to the next process by the feeding and conveying mechanism, and the pressure on the magnetic sheets is maintained during the conveying process to avoid the displacement of the magnetic sheets during the curing process of the anaerobic adhesive, thereby eliminating the missing installation caused by the falling of the magnetic sheets.

[0089] It should be noted that if Figure 4 As shown, the specific number of the positioning jigs 1-12 is five, and the rotating disk 1-11 rotates 72° each time, so that after each rotation of the rotating disk 1-11, the oil pump motors on the five positioning jigs 1-12 correspond one by one to the five stations of the six-axis manipulator 1-2, the dispensing mechanism, the image sensor 1-4, the magnetic sheet feeding mechanism and the height detection mechanism, thereby ensuring the simultaneous operation of the five stations and effectively improving the efficiency of magnetic sheet assembly and detection.

[0090] The specific structure of the dispensing mechanism is as follows: Figure 5As shown, the glue dispensing mechanism includes a glue dispensing slide cylinder 1-31, a glue bottle 1-32 driven to rise and fall by the glue dispensing slide cylinder 1-31, a glue dispensing air pump 1-33 for filling compressed air into the glue bottle 1-32, and a glue dispensing needle nozzle 1-34 connected to the outlet at the bottom end of the glue bottle 1-32; when glue dispensing is required, the glue dispensing slide cylinder 1-31 pushes the glue bottle 1-32 down until the bottom end of the glue dispensing needle nozzle 1-34 approaches the end face of the motor shaft, and the glue dispensing air pump 1-33 fills compressed air into the glue bottle 1-32, so that the anaerobic glue is squeezed out of the glue bottle 1-32 and is applied to the end face of the motor shaft through the glue dispensing needle nozzle 1-34, thereby realizing close-range glue dispensing and effectively ensuring the glue dispensing accuracy. After the glue dispensing is completed, the glue bottle 1-32 and the glue dispensing needle nozzle 1-34 are pulled up by the glue dispensing slide cylinder 1-31 to avoid interference with the forward movement of the oil pump motor.

[0091] The specific structure of the magnetic sheet feeding mechanism is as follows: Figure 6 As shown, the magnetic sheet feeding mechanism includes a magnetic sheet feeding platform 1-51, a magnetic sheet delivery assembly arranged on the magnetic sheet feeding platform 1-51, and a pick-and-place assembly for grabbing the delivered magnetic sheet and crimping it to the end face of the motor shaft.

[0092] The magnetic disk delivery assembly includes a linear slide 1-52 formed on a magnetic disk feeding platform 1-51, a vertically arranged pipe 1-53 sliding along the linear slide 1-52, and a magnetic disk delivery push cylinder 1-54 for pushing the vertically arranged pipe 1-53. The front end of the linear slide 1-52 is formed with a positioning delivery groove 1-55 that can only accommodate one magnetic disk.

[0093] The pick-and-place assembly includes a servo electric cylinder 1-56 installed on the magnetic sheet feeding platform 1-51, a pick-and-place lifting cylinder 1-57 driven by the servo electric cylinder 1-56, and a vacuum claw driven by the pick-and-place lifting cylinder 1-57.

[0094] When the magnetic sheet feeding mechanism is working normally, the magnetic sheet delivery push cylinder 1-54 pushes the vertical arrangement pipe 1-53 forward along the linear slide 1-52 until the bottom end of the vertical arrangement pipe 1-53 is aligned and connected to the positioning delivery groove 1-55, so that the lowest one of the multiple magnetic sheets arranged in the vertical arrangement pipe 1-53 falls into the positioning delivery groove 1-55 under the action of gravity, and the magnetic sheet delivery push cylinder 1-54 pulls the vertical arrangement pipe 1-53 backward, so that the lowest magnetic sheet is blocked and retained in the positioning delivery groove 1-55, realizing the pick-up and placement of the component pick-up point Positioning; after a single magnetic piece is sent out, the servo electric cylinder 1-56 drives the pick-up and placement lifting cylinder 1-57 to move to the vacuum claw part aligned with the positioning and sending groove 1-55, and the pick-up and placement lifting cylinder 1-57 is lowered to the vacuum claw part to fit the magnetic piece, and the vacuum claw part absorbs and picks up the magnetic piece. After the magnetic piece is taken, the height is reset, and the servo electric cylinder 1-56 drives the pick-up and placement lifting cylinder 1-57 to align the taken magnetic piece with the end face of the motor shaft, and the pick-up and placement lifting cylinder 1-57 pushes the vacuum claw part to descend until the magnetic piece fits the end face of the motor shaft, and the installation of the magnetic piece is completed. In summary, the magnetic piece delivery assembly is used to deliver the magnetic pieces one by one, thereby overcoming the mutual adsorption force between the magnetic pieces, ensuring that a single magnetic piece is taken each time, and the installation of the magnetic piece is completed by the pick-up and placement assembly, and the control program is simple and efficient.

[0095] The present application found in the experiment that in order to ensure the installation progress of the magnetic sheet, it is necessary to minimize the gap between the magnetic sheet and the vacuum claw. However, after the gap is reduced, the friction between the magnetic sheet and the hollow claw will increase, which may cause the magnetic sheet to fail to be smoothly removed, resulting in the magnetic sheet being missed. Figure 5 As shown, the vacuum claw member includes an embedded mold 1-581 for embedding the magnetic sheet in the lower end surface, a vacuum tube 1-582 coaxially connected to the embedded mold 1-581, and a demolding cylinder 1-583 for pushing the vacuum tube 1-582 downward to eject; when the magnetic sheet is delivered to the end surface that fits the motor shaft, the vacuum tube 1-582 stops pumping air, and while the vacuum claw member is pulled upward as a whole, the demolding cylinder 1-583 pushes the vacuum tube 1-582 downward, and the downward extension speed of the vacuum tube 1-582 is equal to the overall rising speed of the vacuum claw member, thereby achieving auxiliary demolding of the magnetic sheet and effectively preventing the magnetic sheet from being carried away due to friction.

[0096] The specific structure of the height detection mechanism is as follows: Figure 7As shown, the height detection mechanism includes a height measuring slide cylinder 1-61, a height measuring assembly plate 1-62 driven by the height measuring slide cylinder 1-61, and a height measuring reference plate 1-63 connected to the height measuring assembly plate 1-62 by a slide column; the height measuring assembly plate 1-62 is installed with a first distance sensor 1-64 and a second distance sensor 1-65, the first distance sensor 1-64 is opposite to the upper end surface of the magnetic sheet, and the second distance sensor 1-65 is opposite to the boss of the height measuring reference plate 1-63; a plurality of height measuring pillars 1-66 are arranged on the bottom surface of the height measuring reference plate 1-63, and the plurality of height measuring pillars 1-66 are abutted against a specific plane of the oil pump motor.

[0097] When it is necessary to detect the height of the magnetic sheet, the height measuring slide cylinder 1-61 pushes the height measuring assembly plate 1-62 and the height measuring reference plate 1-63 to descend as a whole. After descending to the moving height, multiple height measuring pillars 1-66 abut against the corresponding surface of the oil pump motor, and the height measuring slide cylinder 1-61 pushes the height measuring assembly plate 1-62 to continue to descend. During this process, the height measuring assembly plate 1-62 and the height measuring reference plate 1-63 gradually approach each other. When the distance detected by the second distance sensor 1-65 reaches a predetermined value, the height measuring slide cylinder 1-61 pushes the height measuring assembly plate 1-62 to continue to descend. Cylinder 1-61 stops pushing the height measuring assembly plate 1-62 down. At this time, the distance between the first distance sensor 1-64 and the corresponding surface of the oil pump motor is a constant A. The first distance sensor 1-64 measures the distance value B from the upper end surface of the magnetic sheet to obtain the relative distance between the magnetic sheet and the corresponding surface of the oil pump motor. The relative distance = constant A-distance value B, that is, the height of the magnetic sheet. It should be noted here that the corresponding surface of the oil pump motor selected in this application is the assembly surface of the oil pump motor. This height detection can ensure the smooth progress of the subsequent processes.

[0098] To prevent the height reference plate 1-63 from being unable to smoothly move down and reset after being separated from the oil pump motor, Figure 6 As shown, a reset spring 1-67 is provided between the height measuring assembly plate 1-62 and the height measuring reference plate 1-63, so as to utilize the combined effect of the spring potential energy of the reset spring 1-67 and the self-gravity of the height measuring reference plate 1-63 to ensure the smooth falling and reset of the height measuring reference plate 1-63, and at the same time, it can also avoid the rigid contact between the height detection mechanism and the oil pump motor, avoiding the hidden danger of collision damage between them.

[0099] The specific structure of the feeding and conveying mechanism is as follows: Fig. 9As shown, the feed conveying mechanism includes a double-row circulating guide rail 1-73 that is repeatedly circling when viewed from above, a synchronous belt 1-74 that is arranged parallel to the double-row circulating guide rail 1-73, and a conveying motor 1-75 for driving the synchronous belt 1-74 to circulate. The output shaft of the conveying motor 1-75 is connected to a driving wheel 1-76 that is connected to the synchronous belt 1-74. The feed conveying mechanism is rotatably installed with a driven wheel 1-77 at each turning point of the double-row circulating guide rail 1-73. A plurality of conveying jigs 1-71 rollers are movably connected to the double-row circulating guide rail 1- 73, and the bottom end is fixed to the synchronous belt 1-74; the feed conveying mechanism limits the moving trajectory of the conveying fixture 1-71 through the double-row circulating guide rail 1-73, and drives the synchronous belt 1-74 through the conveying motor 1-75 to realize the circulating drive of the conveying fixture 1-71, and by limiting the double-row circulating guide rail 1-73 to repeatedly detour, the stroke is increased within a limited area. On the one hand, the temporary storage capacity of the oil pump motor that completes the installation of the magnetic sheet is increased, and on the other hand, the curing time of the anaerobic adhesive under the pressure holding state is increased to ensure the assembly accuracy of the magnetic sheet.

[0100] The specific structure and matching relationship between the pressure holding component 1-72 and the pressure unlocking mechanism are as follows: Figure 8 As shown, the pressure maintaining assembly 1-72 includes a pressure maintaining slide rail 1-721 longitudinally slidably installed on the conveying fixture 1-71, a pressure maintaining pressure arm 1-722 vertically fixed to the top of the pressure maintaining slide rail 1-721, and a pressure maintaining tension spring 1-723 that releases the downward tension of the pressure maintaining pressure arm 1-722; the pressure unlocking mechanism includes a pressure unlocking cylinder 1-81, and a pressure unlocking block 1-82 controlled to rise and fall by the pressure unlocking cylinder 1-81, and the rear end of the pressure maintaining pressure arm 1-722 is provided with an additional force block 1-83 that is inverted L-shaped when viewed from the side, and a groove is formed between the additional force block 1-83 and the pressure maintaining pressure arm 1-722 for the pressure unlocking block 1-82 to extend into.

[0101] When the conveying jig 1-71 is conveyed to the initial end or the final end of the feed conveying mechanism, the groove formed by the additional force block 1-83 and the pressure holding arm 1-722 forms a gap to clamp the pressure unlocking block 1-82, and the pressure unlocking cylinder 1-81 pushes the pressure unlocking block 1-82 upward, and the force transmission of the additional force block 1-83 pushes the pressure holding arm 1-722 upward, thereby ensuring that the oil pump motor is smoothly placed in or taken out of the conveying jig 1-71; when the conveying jig 1-71 is at other positions except the initial end or the final end, the pressure holding tension spring 1-723 releases its elastic potential energy to tighten the pressure holding arm 1-722, thereby ensuring that the pressure holding arm 1-722 is pressed tightly against the magnetic sheet.

[0102] like Fig. 20The figure shows a schematic diagram of the structure of the power supply end cover to be processed, which includes a main structure 91, the main structure 91 is open at one end, and the open end is provided with a mounting lug 92, and the mounting lug 92 is provided with a through hole 93. The bottom surface of the opening of the main structure 91 is provided with a plurality of deformable pins 94, and the main structure 91 is fixed and electrically connected to a substrate 95 by the deformable pins 94.

[0103] like Figure 1 , Fig.10 , Fig.11 , Fig.13 As shown, the end cap pre-processing device includes a pre-processing workbench 2, and the pre-processing workbench 2 is provided with an end cap feeding mechanism, a substrate feeding mechanism, a laser engraving mechanism, a flipping and transferring mechanism and a substrate pressing mechanism; the end cap feeding mechanism includes a manual end cap feeding seat 2-11, and an end cap feeding clamping and feeding assembly, the manual end cap feeding seat 2-11 has a horizontal surface for the surface of the assembly lug 92 to fit, and the manual end cap feeding seat 2-11 is provided with an end cap positioning pin 2-12 which is interference-fitted with the through hole 93; the substrate feeding mechanism includes a manual substrate feeding seat 2-21, and a substrate feeding suction and feeding assembly, the manual substrate feeding seat 2-21 is provided with at least two planar positioning columns 2-22, the end faces of the two planar positioning columns 2-22 are abutted against the same horizontal plane of the substrate 95, and the top of the planar positioning column 2-22 is provided with a substrate positioning pin 2-23 which is interference-fitted with two holes corresponding to the substrate 95.

[0104] When the present application is in normal operation, workers place the power supply end cover and the substrate 95 on the manual end cover loading seat 2-11 and the manual substrate loading seat 2-21 respectively; the end cover loading clamping and conveying assembly delivers the end cover to the laser engraving mechanism, and after the laser engraving mechanism completes the engraving of the identification QR code, the flipping and conveying mechanism flips the power supply end cover to the opening facing downward and delivers it to the substrate pressing mechanism. At the same time, the substrate loading suction and conveying assembly delivers the substrate 95 to the substrate pressing mechanism; when the power supply end cover and the substrate 95 are in place, the substrate pressing mechanism completes the crimping assembly of the two; the power supply end cover with the substrate 95 installed is delivered by the flipping and conveying mechanism; in order to ensure the smooth progress of the automated assembly, the present application performs the following steps on the power supply end cover: The source end cover and the substrate 95 are positioned by manual loading. The power supply end cover is positioned horizontally by fitting the plane of the manual end cover loading seat 2-11 with the surface of the lug 92. The angle of the power supply end cover is positioned by plugging the end cover positioning pin 2-12 into the through hole 93. The substrate 95 is positioned horizontally by fitting with the top end surface of the plane positioning column 2-22. The angle of the substrate is positioned by plugging the substrate positioning pin 2-23 into the corresponding hole. The horizontal and angle positioning of the substrate 95 and the power supply end cover are completed in the manual loading stage, and the loading and positioning of the two are achieved, effectively ensuring the assembly accuracy in the press-fitting stage.

[0105] The present application has found in the experiment that the power supply end cover and the substrate 95 need to be manually loaded by workers, which may cause the risk of collision between the end cover loading clamping and feeding components and the substrate loading suction and feeding components. Figure 1 , Figure 2 As shown, the end cover loading mechanism and the substrate loading mechanism also include a manual loading slide cylinder 2-13, which is used to drive the manual end cover loading seat 2-11 and the manual substrate loading seat 2-21 to move forward and backward; when the power supply end cover or the substrate 95 is taken away, the manual end cover loading seat 2-11 or the manual substrate loading seat 2-21 is pushed to the worker at this workstation by the manual loading slide cylinder 2-13, which reduces the safety hazard of collision on the one hand, and reminds the worker that the power supply end cover or the substrate 95 has been taken away (especially the substrate 95 is small in size and easy to be missed).

[0106] The specific structure of the end cover feeding clamping assembly is as follows: Figure 3 As shown, the end cover feeding clamping assembly includes an end cover feeding servo electric cylinder 2-14, an end cover feeding lifting cylinder 2-15 driven by the end cover feeding servo electric cylinder 2-14, and an end cover feeding pneumatic clamp 2-16; the end cover feeding servo electric cylinder 2-14 is used to control the Y-axis movement, and the feeding lifting cylinder 2-15 is used to control the Z-axis movement, and the end cover feeding pneumatic clamp 2-16 is used to clamp and release the power supply end cover, and the above three actions are combined to realize the feeding of the end cover, and the structure is simple and the control is easy.

[0107] The specific structure of the substrate feeding suction and delivery component is as follows: Figure 4 As shown, the substrate loading suction and transporting assembly includes a substrate loading servo electric cylinder 2-24, a substrate loading lifting cylinder 2-25 driven by the substrate loading servo electric cylinder 2-24, a substrate loading suction cup 2-26 driven by the substrate loading lifting cylinder 2-25, and a substrate horizontal transport structure; the substrate horizontal transport structure includes a substrate horizontal transport seat 2-27, a substrate horizontal transport cylinder 2-28 for driving the substrate horizontal transport seat 2-27, and a substrate pushing cylinder 2-29 installed on the substrate horizontal transport seat 2-27 and applying an upward thrust to the substrate, and the substrate horizontal transport seat 2-27 is provided with a plane positioning column 2-22 and a substrate positioning pin column 2-23.

[0108] When the manual substrate loading seat 2-21 is pushed to the loading position by the manual loading slide cylinder 2-13, the substrate loading suction cup 2-26 is driven by the substrate loading servo electric cylinder 2-24 and the substrate loading lifting cylinder 2-25 to move to the suction position for sucking the substrate 95; after the substrate 95 is sucked, the substrate loading suction cup 2-26 is driven by the substrate loading servo electric cylinder 2-24 and the substrate loading lifting cylinder 2-25 to move until the substrate 95 is attached to the substrate horizontal feeding seat 2-27, and at the same time, the substrate 95 is sucked. A plane positioning column 2-22 and a substrate positioning pin 2-23 are arranged on the substrate horizontal feeding seat 2-27 to realize the re-positioning of the substrate 95; the substrate 95 on the substrate horizontal feeding seat 2-27 is driven by the displacement of the substrate horizontal feeding cylinder 2-28 and the substrate pushing cylinder 2-29, and is sent into the pressing part of the substrate pressing mechanism; in summary, the substrate loading and suction assembly is provided with a substrate horizontal feeding structure, which realizes feeding from bottom to top on the one hand, and realizes the secondary positioning of the substrate 95 on the other hand.

[0109] The specific structure of the laser engraving mechanism is as follows: Fig.12 , Fig.14 As shown, the laser engraving mechanism includes a darkroom box 2-31, a laser marking machine 2-32 (the optional model is Keyence mdx1000) fixed to the darkroom box 2-31 and through which light is injected from top to bottom, a marking carrier 2-33 for positioning and placing the power supply end cover, and a marking electric cylinder 2-34 for driving the marking carrier 2-33 to enter and exit the darkroom box 2-31. The entrance and exit of the darkroom box 2-31 are provided with a lifting box door 2-35 controlled by a cylinder, and the marking carrier 2-33 is provided with an end cover positioning pin 2-12.

[0110] When the end cover loading and clamping assembly delivers the power end cover to the marking carrier 2-33, the marking electric cylinder 2-34 drives the marking carrier 2-33 to load the power end cover into the darkroom box 2-31, and the lifting box door 2-35 of the darkroom box 2-31 is closed, and the laser marking machine 2-32 completes the engraving of the identification QR code on the power end cover; after the engraving of the identification QR code is completed, the lifting box door 2-35 is opened, and the marking electric cylinder 2-34 drives the marking carrier 2-33 to reset, waiting for the flipping and transfer mechanism to take the marked power end cover; in summary, laser marking is completed in the darkroom box 2-31, which effectively prevents the laser light from affecting the workers' eye health, and the marking carrier 2-33 is additionally provided with an end cover positioning pin 2-12 to realize the secondary positioning and restriction of the power end cover, which effectively prevents the power end cover from losing its positioning during the marking process.

[0111] The specific structure of the flip transfer mechanism is as follows: Fig.16As shown, the flip transfer mechanism includes a flip transfer slide 2-41, a flip transfer electric cylinder 2-42 for driving the flip transfer slide 2-41 to slide along the track, a flip feed component installed on the flip transfer slide 2-41, and a delivery component installed on the flip transfer slide 2-41; the power supply end cover pre-processing device for the oil pump motor production line also includes an end cover processing connection carrier 2-61, and the end cover processing connection carrier 2-61 is connected to the connection electric cylinder 2-62 for driving; the spacing between the flip feed component and the delivery component is equal to the power supply end cover by the laser engraving machine The transfer distance from the structure to the substrate pressing mechanism is equal to the transfer distance from the power supply end cover from the substrate pressing mechanism to the end cover processing connection carrier 2-61; the flip feeding component includes a feeding lifting cylinder 2-43, a feeding rotating cylinder 2-44 driven by the feeding lifting cylinder 2-43, and a feeding pneumatic clamp 2-45 driven by the feeding rotating cylinder 2-44; the delivery component includes a delivery lifting cylinder 2-46, a delivery feeding cylinder 2-47 driven by the delivery lifting cylinder 2-46, and a delivery pneumatic clamp 2-48 driven by the delivery feeding cylinder 2-47.

[0112] When the flip transfer mechanism is working normally, the flip transfer electric cylinder 2-42 drives the flip transfer slide 2-41 to retreat and reset; the inlet lifting cylinder 2-43 drives the inlet pneumatic clamp 2-45 to descend to complete clamping and then ascend and reset; at the same time, the outlet feeding cylinder 2-47 drives the outlet pneumatic clamp 2-48 to feed, and the outlet lifting cylinder 2-46 drives the outlet feeding cylinder 2-47 to descend to complete clamping, then ascend and retreat and reset; the flip transfer electric cylinder 2-42 drives the flip transfer slide 2-41 to move forward, and the inlet rotating cylinder 2-44 drives the inlet pneumatic clamp 2-45 to move forward. After the flipping of the power supply end cover is completed, the power supply end cover that has completed laser engraving is sent to the substrate pressing mechanism by the sending-in lifting cylinder 2-43, and the power supply end cover that has completed substrate 95 pressing is sent to the end cover processing connection carrier 2-61 by the sending-out feed cylinder 2-47 and the sending-out lifting cylinder 2-46. In summary, the flipping and transfer mechanism adopts the flipping and transfer slide plate 2-41 to control the synchronous displacement of the flipping and feeding assembly and the sending-out assembly, thereby realizing the flipping of the power supply end cover, the sending-in of the power supply end cover, and the sending-out of the power supply end cover. The three steps are carried out simultaneously, which effectively improves production efficiency.

[0113] The specific structure of the substrate pressing mechanism is as follows: Fig.17As shown, the substrate pressing mechanism includes a substrate pressing frame 2-51, an end cover lifting and positioning assembly installed at the lower part of the substrate pressing frame 2-51, and a substrate pressing assembly installed at the upper part of the substrate pressing frame 2-51; the end cover lifting and positioning assembly includes a lifting reference panel 2-52, a lifting and positioning seat 2-53, and a lifting cylinder 2-54 for driving the lifting and positioning seat 2-53, the lifting reference panel 2-52 has a pressing through hole 2-55, and the lifting and positioning seat 2-53 is provided with an end cover positioning pin 2-12; the substrate pressing assembly includes a lower pressing frame 2-56, a pressing cylinder 2-57 for driving the lower pressing frame 2-56 to rise and fall, and a pressing suction cup 2-58 fixed to the bottom surface of the lower pressing frame 2-56, the lower pressing suction cup 2-58 is opposite to the pressing through hole 2-55, and the substrate positioning pin 2-23 is provided on its bottom surface.

[0114] When the substrate pressing mechanism is working normally, the lifting and positioning seat 2-53 receives the power end cover sent in, and the lifting and positioning seat 2-53 is pushed up by the lifting cylinder 2-54 until the surface of the assembly lug 92 of the power end cover is in contact with the lower surface of the lifting reference panel 2-52; at the same time, the substrate 95 sent in is received by the pressing cup 2-58, and the pressing frame 2-56 is pushed down by the pressing cylinder 2-57 until the substrate 95 passes through the pressing through hole 2-55 and the deformable pin 94 is inserted; the pressing cup 2-58 stops sucking air, Resetting the lower press frame 2-56 and the lifting and positioning seat 2-53 can complete the assembly of the base plate 95 and the power supply end cover; in summary, the lifting reference panel 2-52 is used to perform the final horizontal plane positioning of the power supply end cover before press-fitting, and the positioned horizontal plane is the same plane as the horizontal plane when the end cover is manually loaded, that is, both are the planes of the assembly lugs 92, which effectively ensures the positioning accuracy of the horizontal plane, and uses the end cover positioning pins 2-12 and the base plate positioning pins 2-23 to perform the final angular positioning of the power supply end cover and the base plate 95, further ensuring the assembly accuracy of the two.

[0115] The power supply end cover of the oil pump motor with high-precision control needs to be equipped with an insulator, and an insulator installation mechanism is also provided; Fig.18 , Fig.19 As shown, the insulator installation mechanism includes an insulator assembly turntable 2-71, a three-axis lifting robot 2-72 arranged in sequence around the insulator assembly turntable 2-71, an insulator feeding assembly, a multi-point laser sensor 2-74 (optional model is Keyence ix-150), a first hot melt assembly, a second hot melt assembly, and a CCD detection camera 2-77 (optional model is Keyence CA-035M).

[0116] After the power end cover assembled on the substrate 95 is placed on the end cover processing and connection carrier 2-61, the three-axis lifting robot 2-72 takes the power end cover and places it on an empty station of the insulator assembly turntable 2-71. The insulator assembly turntable 2-71 rotates 60° as a whole, driving the six power end covers to move forward one station synchronously.

[0117] After the insulator assembly turntable 2-71 completes rotation, the insulator feeding assembly places the insulator at the corresponding position of the power supply end cover.

[0118] At the same time, the multi-point laser sensor 2-74 detects the flatness of the placement of the insulator.

[0119] At the same time, the first hot melt component completes the melting of part of the top of the riveted column. It should be noted here that if the multi-point laser sensor 2-74 detects that the flatness of the previous insulator does not meet the requirements, the first hot melt component will not work.

[0120] At the same time, the second hot melt component completes the melting of the remaining part of the top of the riveted column. It should be noted here that if the multi-point laser sensor 2-74 detects that the flatness of the first two insulators does not meet the requirements, the second hot melt component will not work.

[0121] At the same time, the CCD detection camera 2-77 detects the shape of the top of the riveted column after re-solidification. It should be noted here that only the power end cover that has been melted by the second hot melt component is inspected.

[0122] At the same time, the three-axis lifting robot 2-72 removes and places the power supply end cover at the corresponding position. There are three specific prevention positions. The first is the placement point for qualified products detected by the CCD detection camera 2-77, the second is the placement point for unqualified product A detected but unqualified by the CCD detection camera 2-77, and the third is the placement point for unqualified product B detected by the CCD detection camera 2-77.

[0123] In summary, this embodiment realizes the automated installation and detection of insulators by adding an insulator installation mechanism.

[0124] The specific structure of the insulator feeding assembly is as follows: Fig.19As shown, the insulator feeding assembly includes a circulating conveyor belt 2-731, insulator carriers 2-732 arranged in double rows on the circulating conveyor belt 2-731, an insulator three-axis motion structure 2-733, and an insulator suction cup 2-734 driven by the insulator three-axis motion structure 2-733; when the insulator feeding assembly is in operation, a worker places the insulator on the insulator carrier 2-732, and the insulator carrier 2-732 is circulated by the circulating conveyor belt 2-731. When any insulator carrier 2-732 carrying an insulator is at the end of the circulating conveyor belt 2-731, the circulating conveyor belt 2-731 stops running, and the insulator suction cup 2-734 is driven by the insulator three-axis motion structure 2-733, and the insulator suction cup 2-734 sucks the insulator, and then the insulator is placed at the corresponding position of the power supply end cover; with the above structure, only one worker is needed to complete the supply of insulators, effectively reducing labor costs.

[0125] The specific structures of the first hot melt component and the second hot melt component are as follows: Fig.19 As shown, the first hot melt component and the second hot melt component both include a hot melt lifting structure 2-755, and a plurality of riveted hot melt heads 2-756 driven by the hot melt lifting structure 2-755. The first hot melt component is provided with three riveted hot melt heads 2-756, and the second hot melt component is provided with two riveted hot melt heads 2-756. Five riveted hot melt heads 2-756 are allocated to the first hot melt component and the second hot melt component, which effectively ensures that the melting requirements of the five riveted columns are completed in a small space.

[0126] like Figure 1 , Fig.21 , Fig. 22 , Fig.23 The end cover assembly device includes an assembly workbench 3, and the assembly workbench 3 is provided with an end cover conveying mechanism, a main body conveying mechanism, a pre-installation mechanism, a five-axis translation manipulator 3-4, a horizontal riveting mechanism and a vertical riveting mechanism; the horizontal riveting mechanism includes a horizontal riveting turntable 3-51 driven by a rotating cylinder, a horizontal riveting slide 3-52 relatively sliding on both sides of the horizontal riveting turntable 3-51, a horizontal riveting pusher 3-53 fixed to the horizontal riveting slide 3-52, and a horizontal riveting cylinder 3-54 for driving the horizontal riveting slide 3-52; the vertical riveting mechanism includes a vertical riveting turntable 3-61 driven by a rotating cylinder, a vertical riveting slide 3-62 that moves up and down just above the vertical riveting turntable 3-61, a vertical riveting head 3-63 relatively fixed to the lower end surface of the vertical riveting slide 3-62, and a vertical riveting electric cylinder 3-64 for driving the vertical riveting slide 3-62.

[0127] When the present application is in normal operation, the end cover conveying mechanism and the main body conveying mechanism respectively send the power supply end cover and the motor main body into the pre-installation mechanism. After the pre-clamping of the two is completed by the pre-installation mechanism, the five-axis translation manipulator 3-4 sends the pre-installed power supply end cover and the motor main body into the horizontal riveting mechanism. After the horizontal riveting mechanism completes the inward bending of the riveted deformed plate 98, the five-axis translation manipulator 3-4 sends the water-riveted power supply end cover and the motor main body into the vertical riveting mechanism. After the vertical riveting mechanism completes the downward bending of the horizontal section of the riveted deformed plate 98, the five-axis translation manipulator 3-4 The assembled oil pump motor is sent out; the specific working process of the horizontal riveting mechanism is to complete the pre-installed power supply end cover and the motor body to be embedded in the horizontal riveting turntable 3-51, and the horizontal riveting cylinder 3-54 pushes the horizontal riveting slide 3-52 to approach the horizontal riveting turntable 3-51 until the two horizontal riveting push heads 3-53 push the corresponding two riveted deformation plates 98 to bend inward 90°. After the deformation of the two riveted deformation plates 98 is completed, the horizontal riveting cylinder 3-54 pulls the horizontal riveting slide 3-52 to reset, and the power supply end cover and the motor body are driven by the horizontal riveting turntable 3-51 to rotate 6 0°, repeat the above horizontal riveting process, after completing the bending of the third and fourth riveted deformed plates 98, the horizontal riveting turntable 3-51 drives the power supply end cover and the motor body to rotate 60° again, and repeat the above horizontal riveting process to complete the bending of the fifth and sixth riveted deformed plates 98; the specific working process of the vertical riveting mechanism is that the power supply end cover and the motor body that have completed horizontal riveting are embedded in the vertical riveting turntable 3-61, and the vertical riveting electric cylinder 3-64 drives the vertical riveting slide 3-62 and the vertical riveting head 3-63 to descend, completing the secondary shaping of the two riveted deformed plates 98 Change, that is, bend downward and embed into the embedding groove 97, and be driven by the vertical riveting turntable 3-61 to rotate 60° twice, and complete the secondary deformation of two riveted deformed plates 98 twice, so as to realize the riveting and bending of six riveted deformed plates 98, and ensure the assembly strength of the power supply end cover and the motor body; in summary, the present application rivets the riveted deformed plate 98 twice through the horizontal riveting mechanism and the vertical riveting mechanism respectively, and combines the rotation to realize the two riveting of multiple riveted deformed plates 98 at multiple angles, so as to realize the technical requirements of automated riveting and fixing the power supply end cover and the oil pump motor body.

[0128] The horizontal riveting mechanism uses two sides to rivet at the same time. It is found in the experiment that there may be a problem that the two riveted deformed plates 98 are bent inwards unevenly, such as Figure 2As shown, the horizontal riveting slide 3-52 is connected to the horizontal riveting movable frame 3-55. The horizontal riveting movable frame 3-55 utilizes a slide rail slider and has mobility along the direction of the line connecting the two horizontal riveting push heads 3-53; so that the horizontal riveting slide 3-52 and the horizontal riveting cylinder 3-54 on both sides have overall sliding mobility, so that when the forces on both sides are uneven, the horizontal riveting movable frame 3-55 slides accordingly, so that the two relative riveted deformation plates 98 are subjected to the same force, thereby ensuring the consistency of the inward bending deformation amount of the two relative riveted deformation plates 98.

[0129] In order to prevent the relative movement between the oil pump motor body and the power supply end cover during the horizontal riveting process, the horizontal riveting mechanism also includes a downward pressure limiting component, such as Fig. 22 As shown, the downward pressure limiting assembly includes a downward pressure limiting frame 3-56, a downward pressure limiting cylinder 3-57 for driving the downward pressure limiting frame 3-56 to rise and fall, and a downward pressure limiting rotating head 3-58 rotatably connected to the downward pressure limiting frame 3-56; before horizontal riveting, the downward pressure limiting cylinder 3-57 drives the downward pressure limiting frame 3-56 to move downward until the downward pressure limiting rotating head 3-58 presses the top surface of the power supply end cover, thereby limiting the relative movement of the power supply end cover and the oil pump motor body, and the downward pressure limiting rotating head 3-58 contacts the power supply end cover, thereby preventing the rotation of the oil pump motor body and the power supply end cover from being interfered.

[0130] In order to achieve the restrictions on the oil pump motor body and power supply end cover during the vertical riveting process, such as Fig.23 , Fig.24 As shown, the vertical riveting slide 3-62 slides between the two vertical riveting heads 3-63 and is rotatably connected with an elastic limiting disk 3-65, and the elastic limiting disk 3-65 is fixedly installed with a plug-in column 3-66 and is slidably and rotatably connected with the vertical riveting slide 3-62, and a compression spring 3-67 is provided between the plug-in column 3-66 and the vertical riveting slide 3-62; during the downward movement of the vertical riveting slide 3-62, the elastic limiting disk 3-65 first presses the power supply end cover, and then the vertical riveting head 3-63 presses the riveted deformation plate 98, thereby avoiding relative displacement of the oil pump motor body and the power supply end cover during the vertical riveting process, and at the same time, the plug-in column 3-66 gives the elastic limiting disk 3-65 the degree of rotation and extension, thereby avoiding interference with the rotation of the oil pump motor body and the power supply end cover and the maximum descending distance of the vertical riveting slide 3-62.

[0131] It should be noted that if Fig.23 As shown, the vertical riveting mechanism also includes an image sensor 3-68 (Keyence IV-150 image recognition sensor can be selected) for detecting whether there are cracks in the riveted deformed plate 98 after bending. If cracks are detected in the riveted deformed plate 98 after bending, the five-axis translation robot 3-4 will place it in the defective grade.

[0132] The five-axis translation manipulator 3-4 needs to complete the loading of the pre-installed oil pump motor, the transfer of the oil pump motor between the horizontal riveting mechanism and the vertical riveting mechanism, and the unloading of the oil pump motor. There are many tasks to be undertaken and may not be able to adapt to the efficiency of other mechanisms. For this reason, Fig.25 As shown, the picking end of the five-axis translation manipulator 3-4 is provided with a conversion rotary cylinder 3-41, and the conversion rotary cylinder 3-41 drives a conversion connecting plate 3-42, and conversion pneumatic clamps 3-43 are respectively installed at both ends of the conversion connecting plate 3-42, so that the five-axis translation manipulator 3-4 is equipped with two conversion pneumatic clamps 3-43, which improves its working efficiency and achieves the technical effect of adapting the efficiency of other mechanisms.

[0133] Compared with the prior art glue-fixed assembly, the assembly of the oil pump motor body and the power supply end cover by riveting has the advantage of being detachable, but the disadvantage of poor sealing. In order to improve the sealing of the assembly, the assembly device of the oil pump motor body and the power supply end cover also includes a sealing ring assembly mechanism, such as Figure 6 As shown, the sealing ring assembly mechanism includes a sealing ring feeding turntable 3-71, three sealing ring sleeve columns 3-72 vertically fixed at equal angles to the sealing ring feeding turntable 3-71, a sealing ring pushing assembly, a sealing ring two-axis motion structure 3-73, a sealing ring suction cup 3-74 driven by the sealing ring two-axis motion structure 3-73, and a sealing ring assembly carrier 3-75.

[0134] When the sealing ring assembly mechanism is working, the sealing ring feeding turntable 3-71 rotates to drive the sealing ring sleeve column 3-72 full of sealing rings to rotate to the taking position of the sealing ring suction cup 3-74, and the sealing ring two-axis motion structure 3-73 drives the sealing ring suction cup 3-74 to take the sealing ring, and then drives the sealing ring suction cup 3-74 to the sealing ring assembly carrier 3-75 to complete the installation of the sealing ring, and then after taking a sealing ring each time, the sealing ring pusher assembly pushes the sealing ring on the corresponding sealing ring sleeve column 3-72 to move up one as a whole height to ensure that the picking point of the sealing ring suction cup 3-74 is constant. When the sealing rings on one sealing ring column 3-72 are used up, the sealing ring feeding turntable 3-71 rotates 120°, and the sealing rings are supplied by another sealing ring column 3-72. In summary, the present application adds a sealing ring assembly mechanism to install the sealing ring on the power supply end cover, which effectively ensures the assembly sealing of the power supply end cover and the oil pump motor body. At the same time, the sealing rings are supplied in turn by three sealing ring columns 3-72, thereby ensuring the continuity of the sealing ring supply.

[0135] The specific structure of the sealing ring push assembly is as follows: Fig.26As shown, the sealing ring pushing assembly includes a sealing ring pushing ring 3-76 that slides along the sealing ring column 3-72, a sealing ring pushing two-axis motion structure 3-77, and a sealing ring pushing clamp 3-78 driven by the sealing ring pushing two-axis motion structure 3-77. The sealing ring pushing clamp 3-78 clamps the sealing ring column 3-72 in a gap and abuts against the lower end surface of the sealing ring pushing ring 3-76.

[0136] When the sealing ring feeding turntable 3-71 rotates the sealing ring column 3-72 full of sealing rings into place, the sealing ring pushing two-axis motion structure 3-77 pushes the sealing ring pushing clamp 3-78 to move to the bottom of the sealing ring pushing ring 3-76. When a sealing ring is taken away, the sealing ring pushing two-axis motion structure 3-77 pushes the multiple sealing rings mounted on the sealing ring column 3-72 upward by a distance as a whole via the sealing ring pushing clamp 3-78 and the sealing ring pushing ring 3-76, so that the position of the top sealing ring remains inconvenient, thereby ensuring the convenience of taking the sealing ring.

[0137] The specific structure of the end cover handling mechanism is as follows: Fig.26 As shown, the end cap transport mechanism includes an end cap feeding carrier 3-11, a sealing ring detection carrier 3-12, a defective product carrier 3-13, an end cap transport long plate 3-14 driven by a servo electric cylinder, three end cap transport two-axis motion structures 3-15 fixed on the end cap transport long plate 3-14 at equal intervals, and an end cap transport clamping claw cylinder 3-16 driven by the end cap transport two-axis motion structure 3-15. An image sensor 3-68 (Keyence IV-150 image recognition sensor can be used) is arranged opposite to the sealing ring detection carrier 3-12 to detect whether the sealing ring is installed in place. The defective product carrier 3-13 is driven by the servo electric cylinder for translation; thereby realizing the simultaneous transport of three power supply end caps, the first one is the feeding of the power supply end caps, the second one is the detection of the installation of the power supply end cap sealing rings, and the third one is the discharge of defective products or sending them to the pre-installation mechanism, which effectively improves the transport efficiency of the power supply end caps.

[0138] The specific structure of the main transport mechanism is as follows: Fig.21 As shown, the main body transporting mechanism includes a main body transporting two-axis motion structure 3-21, a main body transporting turning cylinder 3-22 driven by the main body transporting two-axis motion structure 3-21, and a main body transporting pneumatic clamp 3-23 driven by the main body transporting turning cylinder 3-22. On the premise of realizing the transport of the oil pump motor body, the turning of the oil pump motor body is completed to ensure the smooth pre-installation of the oil pump motor body and the power supply end cover.

[0139] The specific structure of the pre-installation mechanism is as follows: Fig.21As shown, the preloading mechanism includes a preloading platform 3-31 driven by a servo electric cylinder, a preloading lower press seat 3-32, and a preloading cylinder 3-33 for driving the preloading lower press seat 3-32 to rise and fall. The preloading platform 3-31 is driven to move by the servo electric cylinder, and after receiving the power supply end cover and the oil pump motor body in turn, they are carried to the bottom of the preloading lower press seat 3-32, and the preloading lower press seat 3-32 is driven to descend by the preloading cylinder 3-33, thereby completing the crimping preloading of the power supply end cover and the oil pump motor body.

[0140] like Figure 1 , Fig.29 , Fig.30 , Fig.31 As shown, the program burning sealing device includes a burning workbench 4, and the burning workbench 4 is provided with a burning feeding mechanism, a program burning mechanism, a burning interface gluing mechanism, a gluing capping transfer mechanism, a burning interface capping mechanism, a burning discharging mechanism and a burning conveying mechanism; the burning interface gluing mechanism includes a burning gluing seat 4-31 driven by a servo electric cylinder, a burning gluing lifting cylinder 4-32 with a column installed on the burning gluing seat 4-31, an air pressure gluing bottle 4-33 driven by the burning gluing lifting cylinder 4-32, and a burning gluing carrier 4-34 driven by a servo electric cylinder; the burning interface capping mechanism includes a capping feeding vibration plate 4-51, a capping two-axis motion structure 4-52, a capping vacuum suction cup 4-53 driven by the capping two-axis motion structure 4-52, and a capping positioning seat 4-54.

[0141] When the present application is in normal operation, the program burning mechanism completes the burning of the control program. After the program burning is completed, the burning feeding mechanism sends the oil pump motor to the burning interface gluing mechanism. After the burning interface gluing mechanism completes the gluing of the burning interface, the gluing capping transport mechanism sends the glued oil pump motor into the burning interface capping mechanism. After the burning interface capping mechanism completes the installation of the sealing cover, the gluing capping transport mechanism sends the capped oil pump motor out, and the burning discharging mechanism sends the oil pump motor into the burning conveying mechanism, and finally sends it out by the burning conveying mechanism. The specific working process of the burning interface gluing mechanism is that when the oil pump motor is in the burning gluing carrier 4-31, the burning gluing carrier 4-31 sends the oil pump motor to the gluing position, and the burning gluing seat 4-34 moves to the air pressure gluing bottle 4-33. Located just above the burning interface of the oil pump motor, the burning glue coating lifting cylinder 4-32 pushes the pneumatic glue coating bottle 4-33 down to approach the oil pump motor. After the pneumatic glue coating bottle 4-33 applies glue to the burning interface, the pneumatic glue coating bottle 4-33 rises and retreats to reset, preventing the removal and delivery of the oil pump motor from being interfered with; the specific working process of the burning interface capping mechanism is that when the oil pump motor is in the capping positioning seat 4-54, the sealing cover is delivered by the capping feeding vibration plate 4-51, and the movement of the capping vacuum suction cup 4-53 is controlled by the capping two-axis motion structure 4-52. After grabbing the sealing cover, the sealing cover is pressed and fixed to the program recording entrance of the oil pump motor; in summary, the present application adopts glue coating combined with pressure capping to achieve sealing of the program burning port of the oil pump motor, effectively ensuring the actual protection level of the oil pump motor.

[0142] To ensure stable gripping of the sealing cap, Fig.31 As shown, the two-axis motion structure for cover installation is equipped with a cover installation assembly seat 4-55, and the cover installation assembly seat 4-55 is slidably connected to two cover installation telescopic columns 4-56, and a cover installation telescopic plate 4-57 is fixed to the bottom end of the two cover installation telescopic columns 4-56. The specific number of the cover installation vacuum suction cup 4-53 is two, and they are symmetrically installed on the cover installation telescopic plate 4-57, so as to realize the suction of both sides of the sealing cover, and effectively improve the grasping stability; to ensure the press-fitting accuracy, a pressure detection block 4-58 is fixed on the upper surface of the cover installation telescopic plate 4-57, and the cover installation assembly seat 4-55 is fixedly equipped with a pressure sensor 4-59, and the pressure sensor 4-59 is abutted and matched with the pressure detection block 4-58, so that when the sealing cover is press-fitted, the pressure sensor 4-59 detects the downward pressure applied to the sealing cover through the pressure detection block 4-58, which effectively improves the accuracy of the press-fitting sealing cover.

[0143] The specific structure of the burning feeding mechanism is as follows: Fig.32As shown, the burning feeding mechanism includes a burning feeding translation seat 4-11 driven by a servo electric cylinder, a burning feeding lifting seat 4-12 moving in the vertical direction of the burning feeding translation seat 4-11 and driven by the servo electric cylinder, and a burning feeding pneumatic clamp 4-13 installed on the burning feeding lifting seat 4-12, and the burning feeding mechanism also includes a program fault carrier 4-14 driven by a slide cylinder; when the oil pump motor completes the burning of the control program, the displacement of the burning feeding translation seat 4-11 and the burning feeding lifting seat 4-12 cooperates with the clamping and release of the burning feeding pneumatic clamp 4-13 to achieve the removal and prevention of the oil pump motor, and a program fault carrier 4-14 is added, so that the oil pump motor that has not successfully completed the program burning can be placed on the program fault carrier 4-14, and the oil pump motor that has successfully completed the program burning is placed on the burning glue coating carrier 4-34.

[0144] The specific structure of the program burning mechanism is as follows: Fig.33 As shown, the program burning mechanism includes a burning positioning clamp 4-21 for clamping the oil pump motor, a program burning feed seat 4-22 driven by a cylinder, a program burning main lifting seat 4-23 connected to the program burning feed seat 4-22 and driven by a cylinder, a high-precision slide cylinder 4-24 installed on the program burning main lifting seat 4-23, and an electrical signal connection needle 4-25 installed on the high-precision slide cylinder 4-24; when the oil pump motor to be burned is placed on the burning positioning clamp 4-21, the program burning feed seat 4-22 moves forward to the electrical signal connection needle 4-25 Directly above the program burning interface, after the program burning main lifting seat 4-23 descends to a predetermined height, the high-precision slide cylinder 4-24 pushes the electrical signal connecting needle 4-25 to slowly insert it into the program burning interface. When the program burning is completed, the electrical signal connecting needle 4-25 moves up and resets, the program burning main lifting seat 4-23 moves up and resets, and the program burning feed seat 4-22 moves back and resets; in summary, the program burning mechanism adopts a two-stage descending motion to push the electrical signal connecting needle 4-25, which effectively reduces the risk of the electrical signal connecting needle 4-25 being damaged by collision while ensuring the lifting efficiency.

[0145] To further ensure the installation accuracy of the sealing cover, Fig.34 As shown, the oil pump motor program burning and sealing device also includes an image sensor 4-60 (Keyence IV-150 image recognition sensor can be selected), so that the image sensor 4-60 detects the sealing cover to ensure the installation accuracy of the sealing cover.

[0146] The specific structure of the glue coating and capping transfer mechanism is as follows: Fig.34As shown, the glue coating and capping transfer mechanism includes a glue cover transfer plate 4-41 driven by a servo electric cylinder, three glue cover transfer two-axis motion structures 4-42 fixed on the glue cover transfer plate 4-41 at equal intervals, and a glue cover transfer pneumatic clamp 4-43 driven by the glue cover transfer two-axis motion structure 4-42; thereby, the simultaneous transfer of oil pump motors at three workstations can be achieved at one time, effectively ensuring the transfer efficiency of the glue coating and capping transfer mechanism.

[0147] The specific structure of the burning and discharging mechanism is as follows: Fig.35 As shown, the burning and discharging mechanism includes a defective capping product carrier 4-61 driven by a slide cylinder, a burning and discharging two-axis motion structure 4-62 supported and installed by a column, and a burning and discharging pneumatic clamp 4-63 driven by the burning and discharging two-axis motion structure 4-62; when the image sensor 4-60 detects that the qualified oil pump motor is on the defective capping product carrier 4-61, the burning and discharging pneumatic clamp 4-63 is driven by the burning and discharging two-axis motion structure 4-62 to pick up and place it on the burning conveying mechanism; when the image sensor 4-60 detects that the unqualified oil pump motor is on the defective capping product carrier 4-61, it is directly sent away from the defective capping product carrier 4-61, and the defective product is taken down by the worker.

[0148] The specific structure of the burning and conveying mechanism is as follows: Fig.36 As shown, the burning conveying mechanism includes a burning conveying double-row guide rail 4-71 that is repeatedly circled and enclosed, a burning conveying carrier 4-72 that is densely slidably arranged along the burning conveying double-row guide rail 4-71, and a burning conveying belt assembly for driving the burning conveying carrier 4-72; the burning conveying belt assembly drives the multiple burning conveying carriers 4-72 to circulate along the burning conveying double-row guide rail 4-71, so that the oil pump motor is placed on the burning conveying carrier 4-72, and the oil pump motor can be unloaded and conveyed, and it has a strong material storage capacity.

[0149] The specific structure of the burning conveyor belt assembly is as follows: Fig.36 As shown, the burning conveyor belt assembly includes a burning conveyor belt 4-73 arranged along the center line of the burning conveyor double-row guide rail 4-71, each burning conveyor wheel 4-74 located at the turning position of the burning conveyor belt 4-73, and a burning conveyor motor 4-75 for driving the burning conveyor wheel 4-74. The burning conveyor belt 4-73 is fixed to the bottom of the burning conveyor carrier 4-72; the burning conveyor wheel 4-74 limits the trajectory of the burning conveyor belt 4-73, and the burning conveyor motor 4-75 drives any burning conveyor wheel 4-74 to rotate, thereby realizing the driving of the burning conveyor carrier 4-72.

[0150] To prevent the sealing cover from loosening when the glue is not completely cured, Fig.37As shown, the burning conveying carrier 4-72 is provided with a capping clamping assembly, which includes a capping clamping slide rail 4-76 slidably connected to the burning conveying carrier 4-72, a capping clamping cross plate 4-77 horizontally fixed to the top of the capping clamping slide rail 4-76, and a capping clamping tension spring 4-78 arranged between the capping clamping cross plate 4-77 and the burning conveying carrier 4-72; when the oil pump motor is on the burning conveying carrier 4-72, the capping clamping tension spring 4-78 releases elastic potential energy to pull down the capping clamping cross plate 4-77, so that the capping clamping cross plate 4-77 is pressed against the sealing end cover, which effectively prevents the sealing cover from loosening when the glue is not completely cured.

[0151] To prevent the cover clamping assembly from interfering with the oil pump motor being placed in and taken out of the burner transport carrier 4-72, as Fig. 9 As shown, both the insertion end and the removal end of the burning conveying mechanism are provided with a cover pressing and unlocking assembly, which includes a cover unlocking force block 4-81 fixed to the cover pressing horizontal plate 4-77, and a cover unlocking force block 4-82 driven to rise and fall by a cylinder. The cover unlocking force block 4-81 is in an inverted L shape when viewed from the side, and cooperates with the cover pressing horizontal plate 4-77 to form a slot for the cover unlocking force block 4-82 to extend into; when the burning conveying carrier 4-72 moves to When the burning and conveying mechanism is at the insertion end or the removal end, the cover unlocking force block 4-82 is in the groove of the cover unlocking force block 4-82. When the oil pump motor needs to be taken out or put in, the cylinder pushes the cover unlocking force block 4-82 upward, and after the force is transmitted by the cover unlocking force block 4-8, the cover clamping cross plate 4-77 can be pushed up and loosened on the sealing end cover, thereby preventing the cover clamping assembly from interfering with the oil pump motor being put in and taken out of the burning and conveying carrier 4-72.
