Description

Technical Field

[0001] The present invention relates to the technical field of potting devices, and more particularly, to a bubble-free and environmentally friendly potting device for the main structure of a linear motor. Background Art

[0002] A linear motor is a transmission device that directly converts electrical energy into linear motion. During the processing, a potting device is required to pot the main structure thereof. The potting technology process is a very important manufacturing technology. It uses a solid medium to fill the interface between two components after removing air before curing, bonding each part together to form an integral structure, achieving the functions of shock absorption, reinforcement, sealing, shaping, and improving the dielectric strength.

[0003] However, when the existing equipment performs potting operations on the main structure of the linear motor, it is easy for dust or debris to fall into the potting box during the process of opening the potting seal cover and placing the workpiece. As a result, when potting, the colloid flowing to the bottom of the potting box forms bubbles at the dust, which will not only affect the appearance of the product but also may affect the performance of the product. Therefore, we have made improvements and proposed a bubble-free and environmentally friendly potting device for the main structure of the linear motor. Summary of the Invention

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. A first moving slot and a third moving slot are arranged on the inner wall of the bottom end of the box body. By driving the support frame to move inside the moving slot through the first cylinder, it is convenient to eject the workpiece after potting. By arranging a dust removal assembly inside the support frame, before placing the workpiece, the dust removal roller is moved upward above the moving slot to make the dust removal roller contact the inner wall of the bottom end of the box body. The workpiece is placed inside the box body, with one end of the workpiece falling on the dust removal roller and the other end falling on the support frame. By starting the first motor to drive the rotation of the first lead screw, the first moving block drives the fixed block and the first gear to move synchronously through the threaded cooperation between the first lead screw and the first moving block. Then, through the meshing between the first gear and the rack, the first gear rotates, so that the dust removal roller rotates during the movement, and further cleans the dust attached to the inner wall of the bottom end of the box body and the lower surface of the workpiece, avoiding the formation of bubbles by the dust falling into the inner wall of the bottom end of the box body during potting and affecting the appearance and performance of the product.

[0018] 2. A first sealing assembly is provided on the sealing cover. The second motor is started to drive the second gear and the third gear to rotate in the same direction, thereby driving the first chain and the second chain to rotate in the same direction, causing the fourth gear and the fifth gear to rotate in the same direction simultaneously, and further driving the first threaded rod and the second threaded rod to rotate in the same direction simultaneously. Through the threaded engagement between the first threaded rod and the second threaded rod and the threaded grooves, the first sealing block can be driven to gradually insert into the sealing groove. Among them, the pitch at the bottom of the first threaded rod and the second threaded rod corresponds to that of the second lead screw, which can ensure that when the second motor and the third motor are started, the distances moved by the sealing cover and the second movable block are the same. Through the above technical solution, automatic sealing of the workpiece can be achieved, and the tightness of the connection between the sealing cover and the box body can be improved, preventing loosening of the connection between the sealing cover and the box body during the glue filling process. In addition, this setting can fix and seal the workpiece when there are certain differences in the workpiece specifications, avoiding the problem of increased glue filling thickness caused by the reduction of the workpiece specifications, and ensuring the performance of the product.

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts belong to the scope of protection of the present invention.

[0031] Specifically refer to Figure 1 、 Figure 3 、 Figure 10, An air - bubble - free and environment - friendly glue - pouring device for the main structure of a linear motor, including a box body 1. The top of the box body 1 is hermetically provided with a sealing cover 5 through a first sealing component 3. Lifting components 4 for driving it are arranged on both sides of the sealing cover 5. A number of glue - pouring ports 6 are arranged on the sealing cover 5. A cavity for placing the main structure of the linear motor is arranged inside the box body 1. A first moving slot 8 is opened at the bottom of the box body 1. A jacking mechanism 2 is movably arranged in the first moving slot 8. The jacking mechanism 2 includes a jacking component 201 for jacking out the workpiece. A dust - removing component 202 for removing dust from the workpiece is arranged on the jacking component 201. The dust - removing component 202 includes a first gear 2026 rotatably arranged inside the jacking component 201, and dust - removing rollers 2027 are respectively arranged on both sides of the first gear 2026.

[0032] Specifically refer to Figure 2 , Figure 3 , Figure 4 , Figure 7 , An integrally - formed first sealing block 9 is arranged on the lower surface of the sealing cover 5. A sealing groove 7 corresponding to the first sealing block 9 is opened at the upper end of the box body 1. The first sealing block 9 is inserted into the sealing groove 7. A first limiting groove 14 and an installation groove 15 are communicated and opened inside the sealing cover 5. A second sealing block 10 for sealing the sealing cover 5 is slidably arranged inside the first limiting groove 14. A telescopic rod 11 and a spring 12 for driving the second sealing block 10 to move are fixedly installed inside the installation groove 15.

[0033] When specifically set, a number of glue - flowing grooves corresponding to the glue - pouring positions on the main structure of the linear motor are respectively arranged on the inner walls of the box body 1 and the sealing cover 5. The first sealing block 9 is slidably connected to the inner wall of the sealing groove 7. A threaded groove 16 is located below the sealing groove 7 and communicated with the sealing groove 7. Before the sealing cover 5 is covered, the upper end of the second sealing block 10 abuts against the lower - end inner wall of the first limiting groove 14 under the action of the spring 12. During the installation of the sealing cover 5, the first sealing block 9 is inserted into the sealing groove 7, and the second sealing block 10 abuts against the groove on one side of the sealing groove 7, causing the telescopic rod 11 and the spring 12 to contract correspondingly. By setting the second sealing block 10, the sealing performance of the device can be improved, and the glue is prevented from flowing into the sealing groove 7.

[0034] Specifically refer to Figure 1 , Figure 3 , The lifting component 4 includes a fixed box 401 fixedly installed on one side of the box body 1 and a third motor 402. The output end of the third motor 402 penetrates through the bottom of the fixed box 401 and is fixedly connected to a second lead screw 403. The second lead screw 403 is rotatably installed inside the fixed box 401. Second moving blocks 404 are respectively fixedly connected to both sides of the sealing cover 5. One second moving block 404 is movably sleeved outside the rod body of the second lead screw 403, and the other second moving block 404 is slidably sleeved outside the rod body of the guide rod 405.

[0035] In this embodiment, the second movable block 404 sleeved outside the rod body of the second lead screw 403 is in threaded engagement with the second lead screw 403, and the second movable block 404 sleeved outside the rod body of the guide rod 405 is in sliding engagement with the guide rod 405. By starting the third motor 402 to drive the second lead screw 403 to rotate, the second movable block 404 moves up and down inside the fixed box 401, thereby driving the sealing cover 5 to move synchronously, realizing the lifting of the sealing cover 5.

[0036] Specifically refer to Figure 2 、 Figure 3 、 Figure 7 、 Figure 8 As shown in

[0037] During specific installation, the second motor 301 is fixedly installed on the upper surface of the limit block 310 through a bracket. On one side of the limit block 310 close to the first chain 304 and the second chain 307, there is an integrally formed convex block for restricting the up-and-down movement of the first chain 304 and the second chain 307. The first chain 304 and the second chain 307 are cross-arranged and the first chain 304 is located above the second chain 307. The first threaded rod 306 and the second threaded rod 309 have the same specifications. By starting the second motor 301 to drive the second gear 302 and the third gear 303 to rotate in the same direction, the first chain 304 and the second chain 307 are driven to rotate in the same direction, so that the fourth gear 305 and the fifth gear 308 rotate in the same direction at the same time, and then the first threaded rod 306 and the second threaded rod 309 are driven to rotate in the same direction at the same time. Through the threaded cooperation between the first threaded rod 306 and the second threaded rod 309 and the thread groove 16, the first sealing block 9 can be gradually inserted into the sealing groove 7. Among them, the pitch at the bottom of the first threaded rod 306 and the second threaded rod 309 corresponds to the second lead screw 403, which can ensure that when the second motor 301 and the third motor 402 are started, the moving distances of the sealing cover 5 and the second movable block 404 are the same. Through the above technical solution, the automatic closing of the workpiece, that is, the linear motor main structure, can be realized, and the tightness of the connection between the sealing cover 5 and the box body 1 can be improved, preventing the connection between the sealing cover 5 and the box body 1 from loosening during the potting process. In addition, this setting can fix and seal the workpiece when there are certain differences in the workpiece specifications, avoiding the problem that the potting thickness increases due to the decrease in the workpiece specifications, and ensuring the performance of the product.

[0038] For specific reference Figure 1 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 10 Specifically referring to

[0039] In this embodiment, the first movable groove 8 is in a mouth shape, the third movable groove 17 is arranged in the middle of the first movable groove 8 and is connected with the first movable groove 8, the third movable groove 17 and the first movable groove 8 are in a sun shape, the output shaft of the first cylinder 2011 is located in the middle of the third movable groove 17, the support frame 2012 is in a sun shape as a whole, the fourth movable groove 2013, the rack 2014, and the second limiting groove 2015 are all arranged on the support frame 2012 inside the third movable groove 17, the two sides of the middle part of the support frame 2012 are respectively slidably fitted with the inner wall of the third movable groove 17, and the inner side of the outer frame of the support frame 2012 is slidably fitted with the inner wall of one side of the first movable groove 8. Through this arrangement, it can play a role in limiting the support frame 2012 during its up and down movement, thereby improving the stability of the support frame 2012 during the lifting process.

[0040] Specific reference Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 10 The dust removal assembly 202 includes a first screw rod 2023 rotatably mounted inside the support frame 2012 and a first motor 2021 for driving the first screw rod 2023 to rotate. The first motor 2021 is located outside the box body 1 and is fixedly mounted on the first mounting seat 2022. A second movable groove 13 for the first screw rod 2023 to move is provided on one side of the box body 1. One end of the first screw rod 2023 passes through the support frame 2012 and the second movable groove 13 and is fixedly connected to the output end of the first motor 2021. The first screw rod 2023 023 A movable sleeve outside the rod body is provided with a first movable block 2024 corresponding to the second limiting groove 2015, the upper end of the first movable block 2024 is fixedly connected to a fixed block 2025, the first gear 2026 is rotatably mounted on the fixed block 2025 and meshes with the rack 2014, the outer sides of the two first gears 2026 are respectively fixedly connected to dust removal rollers 2027, the ends of the dust removal rollers 2027 away from the first gears 2026 are respectively rotatably connected to rollers 2028, and the rollers 2028 are rollingly arranged inside the third limiting groove 2016.

[0041] During the specific setting, the specifications of the second movable groove 13 correspond to the movement trajectory of the first screw rod 2023 in the vertical direction. The support frame 2012 will drive the dust removal assembly 202 to move synchronously during the up and down movement. The final state of the upward movement is that the lower end of the dust removal roller 2027 is flush with the inner wall of the bottom end of the box body 1, which can ensure that the dust removal roller 2027 rolls normally on the inner wall of the box body 1. The final state of the downward movement is that the upper surface of the support frame 2012 is flush with the inner wall of the bottom end of the box body 1, ensuring that the bottom of the colloid is flat.

[0042] It can be understood that in the present application, the first movable block 2024 is in sliding fit with the fixed block 2025. A connecting rod is integrally arranged in the middle of the two first gears 2026. The connecting rod is rotatably sleeved on the upper end of the fixed block 2025. When the lower end of the dust removal roller 2027 moves flush with the inner wall of the bottom end of the box body 1, the first motor 2021 is started to drive the first lead screw 2023 to rotate, so that the first movable block 2024 drives the fixed block 2025 and the first gear 2026 to move in the direction close to the first motor 2021. Through the meshing between the first gear 2026 and the rack 2014, the first gear 2026 rotates around the connecting rod during the movement, thereby driving the two dust removal rollers 2027 to rotate. By arranging rollers 2028 corresponding to the third limiting grooves 2016 at both ends of the dust removal roller 2027, the two ends of the dust removal roller 2027 can be guided and limited, avoiding the inclination of the dust removal roller 2027. During use, the workpiece is placed on the dust removal roller 2027. Through the rolling of the dust removal roller 2027, the dust attached to the lower surface of the workpiece and the upper surface of the inner wall of the box body 1 can be cleaned, thereby avoiding the appearance of air bubbles in the colloid at the bottom of the workpiece during the subsequent glue filling process, avoiding the influence on the product performance, and improving the product quality.

[0043] Specifically refer to Figure 1 、 Figure 3 、 Figure 5 、 Figure 9 On the four side surfaces of the box body 1, second sealing assemblies 203 for sealing the inner wall of the box body 1 are respectively arranged. The second sealing assembly 203 includes second cylinders 2031 respectively fixedly installed on the side surfaces of the box body 1 through second mounting seats 2032. The output ends of the second cylinders 2031 respectively extend into the first movable groove 8 and are fixedly connected with third sealing blocks 2033. A guiding block 2036 slidably connected with the box body 1 is fixedly connected to one side of the third sealing block 2033. Corresponding clamping grooves 2034 are respectively formed in the third sealing block 2033 corresponding to the inner wall of the top end of the first movable groove 8. A guiding groove 2035 for guiding the first mounting seat 2022 is formed in the second mounting seat 2032 close to one side of the first mounting seat 2022. The inner wall of the guiding groove 2035 is slidably connected with the first mounting seat 2022.

[0044] When specifically setting, a convex block integrally formed with the box body 1 is arranged on one side of the top end of the first movable groove 8 and close to the inner wall of the box body 1. The clamping groove 2034 abuts against the convex block, and the lower surface of the clamping groove 2034 is slidably connected with the upper surface of the support frame 2012. After dust removal of the workpiece, by starting the second air cylinder 2031 to drive the third sealing block 2033 to move, the clamping groove 2034 is tightly abutted against the convex block, playing a role in blocking the upper end of the first movable groove 8, so that the inner wall of the box body 1 is in an overall closed state except for the glue flowing groove. By arranging the guide block 2036 to be slidably connected with the box body 1, it can play a guiding role for the third sealing block 2033 and improve the connection accuracy between the third sealing block 2033 and the convex block. By opening a guide groove 2035 at one end of the second mounting seat 2032, it can play a guiding and limiting role for the first mounting seat 2022 during the up and down movement of the first motor 2021, thereby making the first motor 2021 operate smoothly.

[0045] The working principle of the bubble-free environmental protection glue filling device for the linear motor main structure:

[0046] During use, first start the first cylinder 2011 to drive the support frame 2012 and the dust removal component 202 to move upward until the bottom end of the dust removal roller 2027 is moved to be flush with the inner wall of the bottom end of the box body 1. Then start the first motor 2021 to drive the first lead screw 2023 to rotate, so that the first movable block 2024 moves in the direction close to the first motor 2021. The fixed block 2025 is synchronously driven to move through the first movable block 2024. Through the meshing between the first gear 2026 and the rack 2014, the first gear 2026 rotates, thereby driving the dust removal roller 2027 to rotate. Thus, the dust removal roller 2027 rotates while following the movement of the first movable block 2024 until the dust removal roller 2027 moves out of the first movable groove 8. Then turn off the first motor 2021. Subsequently, start the third motor 402 to drive the second lead screw 403 to rotate, so that the second movable block 404 moves upward inside the fixed box 401 until the linear motor main body structure can be placed inside the box body 1, so that one end of the lower surface of the workpiece, i.e., the linear motor main body structure, contacts the dust removal roller 2027, and the other end contacts the upper surface of the support frame 2012. Then continue to start,The first motor 2021 drives the dust removal roller 2027 to move, so that the dust removal roller 2027 rolls on the lower surface of the workpiece and the inner wall of the bottom end of the box body 1, thereby cleaning the dust attached to the bottom of the workpiece and the inner wall of the bottom end of the box body 1. When the dust removal roller 2027 moves to one end of the first motor 2021, the first cylinder 2011 is closed, so that the support frame 2012 drives the dust removal roller 2027 to move downward, making the upper surface of the support frame 2012 flush with the inner wall of the bottom end of the box body 1. At this time, the dust removal roller 2027 moves into the first movable groove 8, and the lower surface of the workpiece fits with the inner wall of the bottom end of the box body 1 and the upper surface of the support frame 2012. Subsequently, four second cylinders 2031 are started simultaneously, and the second cylinders 2031 drive the third sealing block 2033 to move towards the workpiece until the clamping groove 2034 abuts against the convex block at the upper end of the first movable groove 8, so that the third sealing block 2033 fits with the outer side surface of the workpiece. Then, the second motor 301 and the third motor 402 are started, and the second motor 301 drives the second gear 302 and the third gear 303 to rotate synchronously, so that the first chain 304 and the second chain 307 drive the two fourth gears 305 and the fifth gear 308 to rotate simultaneously, making the first threaded rod 306 and the second threaded rod 309 rotate in the same direction at the same time. Through the threaded fit between the second threaded rod 309 and the threaded groove 16, the second threaded rod 309 drives the sealing cover 5 to move downward gradually. At the same time, the third motor 402 drives the second lead screw 403 to rotate at the same speed as the second threaded rod 309, so that the second movable block 404 moves downward by the same distance as the sealing cover 5 until the lower surface of the sealing cover 5 abuts against the upper surface of the workpiece. Subsequently, sealant is poured into the box body 1 through the glue filling port 6, so that the sealant flows along the glue flowing grooves formed on the box body 1 and the sealing cover 5 to the outer surface of the workpiece, and the workpiece is sealed with glue. After the glue cools down, the second motor 301 and the third motor 402 drive the sealing cover 5 to move upward, the second cylinder 2031 is closed, so that the third sealing block 2033 moves away from the workpiece, and the first cylinder 2011 is started to drive the support frame 2012 to move upward, thereby ejecting the workpiece, and finally the workpiece can be taken out.,
