Description

Technical Field

[0001] The present application relates to the technical field of coreless motors, and in particular to a paint stripping and clamping device for producing coreless motors. Background Art

[0002] The coreless motor is a DC permanent magnet servo and control motor, and can also be classified as a micro motor. It has outstanding energy-saving characteristics, sensitive and convenient control characteristics, and stable operating characteristics. Its technological advancement is very obvious. As a high-efficiency energy conversion device, it represents the development direction of motors in many fields.

[0003] The production of coils for coreless motors requires multiple steps, including enameling the wire, winding, heating and shaping, paint stripping, connecting the common line, and installing the coil. Among them, paint stripping is one of the important steps to ensure the quality of the coil. Paint stripping can remove the paint film on the coil, exposing the copper body, thereby improving the conductivity and insulation performance of the coil. Specifically, paint stripping is usually done by holding a clamp. The rotor core cup is clamped with the clamp and placed in a paint stripping furnace filled with a latent solvent (the main components include N-methyldiethanolamine, ammonia organic compounds, alkane derivatives, surfactants, and aluminum corrosion inhibitors, etc.). After the rotor core cup stays in the paint stripping furnace for a certain period of time, the part of the rotor core cup to be stripped is removed from the paint stripping furnace by the clamp. In this way, the paint stripping treatment of the part of the rotor core cup to be stripped is achieved under the combined action of the latent solvent in the paint stripping furnace and the high temperature in the paint stripping furnace. In the process of manually clamping the rotor core cup, the latent solvent in the paint stripping furnace is easily splashed out and burns the person holding the clamp. Utility Model Content

A top plate is arranged near the top end of the pressure rod. The spring is sleeved on the extrusion rod between the top plate and the first through hole, and its top end is connected to the lower surface of the top plate.

[0012] Optionally, each clamping component includes a fixing plate, a push-pull rod, and a clamping plate;

[0013] The top end of the fixing plate is arranged on the lower surface of the connecting plate. The fixing plate is inclined and a second through hole is formed near its bottom end. The two ends of the push-pull rod are respectively hinged to the side wall of the bottom end of the pressure rod and the clamping plate. One end of the clamping plate penetrates through the second through hole and can move back and forth obliquely in the second through hole.

[0014] Optionally, the clamping plate includes an integrally formed inclined plate and a vertical plate;

[0015] The top end of the vertical plate is connected to the bottom end of the inclined plate, and the included angle between the two is an obtuse angle. The top end of the inclined plate penetrates through the second through hole and can move back and forth in the second through hole. The top end of the vertical plate is hinged to the bottom end of the push-pull rod.

[0016] Optionally, a first arc-shaped plate is vertically arranged at the bottom end of each clamping plate, and a plurality of the first arc-shaped plates enclose a first cylindrical barrel for internally supporting the rotor core cup.

[0017] Optionally, a second arc-shaped plate is arranged at the bottom end of each first arc-shaped plate, and a plurality of the second arc-shaped plates enclose a second cylindrical barrel for internally supporting the rotor core cup;

[0018] The inner diameter of the second cylindrical barrel is smaller than the inner diameter of the first cylindrical barrel.

[0019] Optionally, a limiting component for limiting the lever is further included;

[0020] The limiting component includes a limiting block, a vertical limiting rod, and a horizontal limiting rod;

After the paint stripping process is completed, drive the lower support plate to move vertically upwards along the support legs by rotating the lead screw, so that the rotor core cup clamped by the clamping components comes out of the paint stripping furnace. After the painted rotor core cup is cooled, lift the end of the lever away from the elastic component upwards again, so that the end of the lever directly above the elastic component presses the elastic component downwards. At this time, multiple clamping components connected to the bottom end of the elastic component approach and close to each other, so that the rotor core cup is separated from multiple clamping components (during this process, the separated rotor core cup by multiple clamping components can be caught by a tray), and the paint stripping process is completed. Repeat the above process to realize the batch paint stripping operation of the rotor core cup. The above paint stripping process avoids holding the rotor core cup with a hand-held clamp, avoids the potential solvent splashing and scalding the hands and arms of the staff, etc., and improves the safety of the paint stripping process of the rotor core cup. In addition, drive the lower support plate to move vertically up and down along the support legs by the lead screw, so as to realize the rotor core cup entering or coming out of the paint stripping furnace, and realize the precise adjustment of the depth of the rotor core cup entering the paint stripping furnace, thereby improving the precision and stability of the operation during the paint stripping process of the rotor core cup.

Detailed implementation manners

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the following clearly and completely describes the technical solutions in the embodiments of this application. Obviously, the described embodiments are some, but not all, of the embodiments of this application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without making creative efforts also belong to the scope of protection of this application.

[0036] Referring Figures 1 to 8 , this application provides a paint stripping clamping device for the production of coreless motors, including:

[0037] An upper support plate 100, on the lower surface of which a plurality of support legs 101 are vertically arranged. A lower support plate 200 is arranged below the upper support plate 100 on the support legs 101. A plurality of connecting rods 201 are vertically arranged on the lower surface of the lower support plate 200 and a lever 202 is hinged thereto. The bottom ends of the plurality of connecting rods 201 are horizontally provided with a connecting plate 2011; wherein, the top ends of the plurality of connecting rods 201 are fixed to the lower surface of the lower support plate 200, and their bottom ends are fixedly connected to the upper surface of the connecting plate 2011.

[0038] A lead screw 300, the bottom end of which sequentially passes through the upper support plate 100 in a threaded manner and is rotatably connected to the lower support plate 200 (the bottom end of the lead screw 300 is connected to the lower support plate 200 through a bearing, and the bearing can be a ball bearing), and is used to drive the lower support plate 200 to move vertically up and down along the support legs 200; wherein, the plurality of support legs 101 are arranged on the lower surface of the upper support plate 100 at equal intervals and close to the circumferential side of the upper support plate 100, which ensures the stability of the support of the plurality of support legs 101 on the upper support plate 100. The plurality of support legs 101 can be placed on the outer periphery of the paint stripping furnace 1000.

[0039] A plurality of clamping assemblies 400 are arranged on the lower surface of the connecting plate 2011 and are hinged to the outer peripheral wall of the bottom end of the elastic assembly 500 passing through the connecting plate 2011. The top end of the elastic assembly 500 is fixedly connected to one end of the lever 202. Among them, by lifting the end of the lever 202 far from the elastic assembly 500 upward, the end of the lever 202 located directly above the elastic assembly 500 presses the elastic assembly 500 downward. After the bottom end of the elastic assembly 500 drives the clamping assembly 400 to descend to a certain height (during the descent of the elastic assembly 500, the plurality of clamping assemblies 400 approach and close to each other), the bottom end of the elastic assembly 500 extends into the rotor core cup 800. At the same time, release the end of the lever 202 far from the elastic assembly 500, so that the elastic assembly 500 moves upward under its own elastic force and drives the plurality of clamping assemblies 400 to move upward and open. During the upward movement of the clamping assembly 400, the rotor core cup 800 is driven by an external force to move upward with the plurality of clamping assemblies 400, so that the plurality of clamping assemblies 400 are internally supported on the inner wall of the rotor core cup 800, thereby realizing the clamping of the rotor core cup 800 by the plurality of clamping assemblies 400. Furthermore, driven by the rotation of the lead screw 300, the lower support plate 200 moves vertically downward along the support leg 101, so that the rotor core cup 800 clamped by the clamping assembly 400 enters the paint stripping furnace 1000 for paint stripping treatment of the rotor core cup 800. After the paint stripping process is completed, the lower support plate 200 is driven by the rotation of the lead screw 300 to move vertically upward along the support leg 101, so that the rotor core cup 800 clamped by the clamping assembly 400 exits from the paint stripping furnace 1000. After the painted rotor core cup 800 is cooled, lift the end of the lever 202 far from the elastic assembly 500 upward again, so that the end of the lever 202 located directly above the elastic assembly 500 presses the elastic assembly 500 downward. At this time, the plurality of clamping assemblies 400 connected to the bottom end of the elastic assembly 500 approach and close to each other, so that the rotor core cup 800 is separated from the plurality of clamping assemblies 400 (during this process, the rotor core cup 800 separated by the plurality of clamping assemblies 400 can be caught by the tray). The paint stripping process is completed, and the above process is repeated to realize the batch paint stripping operation of the rotor core cup 800.

[0040] During the paint stripping process of the rotor core cup 800 by the paint stripping clamping device for the production of the coreless motor provided in the present application, the situation of holding the rotor core cup 800 with a hand-held clamp is avoided, and the situation that the latent solvent splashes and scalds the hands and arms of the staff is avoided, improving the safety of the paint stripping process of the rotor core cup 800. In addition, by driving the lower support plate 200 to move vertically up and down along the support leg 101 by the lead screw 300, the rotor core cup 800 is realized to enter or exit from the paint stripping furnace 1000, and the precise adjustment of the depth of the rotor core cup 800 entering the paint stripping furnace 1000 is realized, thereby improving the precision and stability of the operation during the paint stripping process of the rotor core cup 800.

[0041] In some embodiments, referring to Figure 4 , the elastic component 500 in the present application includes a pressure rod 501 and a spring 502; specifically, a first through hole 600 with a diameter smaller than the outer diameter of the spring 502 is formed in the middle of the connecting plate 2011, which ensures that the spring 502 can give an upward acting force to the pressure rod 501 during the downward movement of the pressure rod 501. The bottom end of the pressure rod 501 penetrates through the first through hole 600 and can move vertically up and down along the first through hole 600. A top plate 5011 is provided near the top end of the pressure rod 501. The spring 502 is sleeved on the pressure rod 501 between the top plate 5011 and the first through hole 600, and its top end is connected to the lower surface of the top plate 5011.

[0042] In the above embodiment, when the lead screw 300 is rotated, the bottom end of the lead screw 300 presses the lever 202 downward towards one end in the middle of the lower support plate 200. One end of the lever 202 towards the middle of the lower support plate 200 contacts the top end of the pressure rod 501, and the pressure rod 501 moves vertically downward in the first through hole 600, thereby realizing the opening of the plurality of clamping components 400 hinged on the outer peripheral wall of the bottom end of the elastic component 500, and realizing the clamping of the rotor core cup 800 by the plurality of clamping components 400. During the downward movement of the pressure rod 501, the top plate 5011 presses the spring 502 downward, and the spring 502 will give an upward reaction force to the top plate 5011, thereby slowing down the downward movement rate of the pressure rod 501, and thus improving the stability of the rotor core cup being clamped. It should be specifically noted here that a vertical hinge shaft can be provided on the lower surface of the lower support plate 200, and the lever 202 is hinged to the hinge shaft. A preset distance is provided between the top of the lever 202 and the lower surface of the lower support plate 200. The specific value of the preset distance can ensure that one end of the lever 202 away from the elastic component 500 is lifted upward, so that the plurality of clamping components 400 can be closed or opened. Therefore, the specific value of the preset distance can be set according to actual needs, and the present application does not specifically limit it here.

[0043] In some embodiments, referring to Figures 1 to 4 and Figure 6 、 Figure 7 and Figure 8 , each clamping component 400 in the present application includes a fixing plate 401, a push-pull rod 402, and a clamping plate 403; specifically, the top end of the fixing plate 401 is provided on the lower surface of the connecting plate 2011. The fixing plate 401 is inclined and a second through hole 4011 is formed near its bottom end. The two ends of the push-pull rod 402 are respectively hinged to the side wall of the bottom end of the pressure rod 501 and the clamping plate 403. One end of the clamping plate 403 penetrates through the second through hole 4011 and can move back and forth obliquely in the second through hole 4011. Among them, the top end of the fixing plate 401 is fixedly connected to the lower surface of the connecting plate 2011.

[0044] In the above embodiments, during the downward movement of the pressure rod 501, since both ends of the push-pull rod 402 are hinged to the pressure rod 501 and the clamping plate 403 respectively, the end of the push-pull rod 402 hinged to the pressure rod 501 moves downward along with the pressure rod 501. Also, since the clamping plate 403 penetrates through the inclined fixed plate 401, the fixed plate 401 restricts the movement range of the clamping plate 403, causing the clamping plate 403 to move obliquely along the second through hole 4011. Therefore, the end of the pull rod 402 hinged to the clamping plate 402 will push the clamping plate 403 to move obliquely downward along the second through hole 4011, so that the lower ends of the clamping plates 403 approach each other, that is, the multiple clamping plates 403 are closed and the clamping plates 403 that are internally supported on the inner wall of the rotor core cup 800 are separated from the rotor core cup 800.

[0045] During the upward movement of the pressure rod 501, since both ends of the push-pull rod 402 are hinged to the pressure rod 501 and the clamping plate 403 respectively, the end of the push-pull rod 402 hinged to the pressure rod 501 moves upward along with the pressure rod 501. Also, since the clamping plate 403 penetrates through the inclined fixed plate 401, the fixed plate 401 restricts the movement range of the clamping plate 403, causing the clamping plate 403 to move obliquely along the second through hole 4011. Therefore, the end of the pull rod 402 hinged to the clamping plate 402 will pull the clamping plate 403 to move obliquely upward along the second through hole 4011, so that the lower ends of the clamping plates 403 move away from each other, and further, the multiple clamping plates 403 abut against the inner wall of the rotor core cup 800, realizing the internal support of the multiple clamping plates 403 on the rotor core cup 800.

[0046] In some embodiments, referring to Figures 1 to 4 , the clamping plate 403 in the present application includes an integrally formed inclined plate 4031 and a vertical plate 4032; specifically, the top end of the vertical plate 4032 is connected to the bottom end of the inclined plate 4031 and the included angle between them is obtuse. The top end of the inclined plate 4031 penetrates through the second through hole 4011 and can move back and forth in the second through hole 4011, and the top end of the vertical plate 4032 is hinged to the bottom end of the push-pull rod 402. Among them, the setting of the inclined plate 4031 can adjust the tension of the vertical plate 4032, that is, the vertical up and down movement of the pressure rod 501, realizing that the push-pull rod 402 hinged to the pressure rod 501 and the vertical plate 4032 drives the vertical plate 4032 to move. Through the inclined movement of the inclined plate 4031 in the second through hole 4011, the mutual approach and separation of the multiple vertical plates 4032 are realized, thereby realizing the clamping of the multiple vertical plates 4032 on the rotor core cup 800 and the separation of the rotor core cup 800 from the multiple vertical plates 4032.

[0047] In some embodiments, referring to Figure 2 and Figure 3, at the bottom end of each clamping plate 403 in the present application, a first arc-shaped plate 700 is vertically arranged, and a plurality of first arc-shaped plates 700 enclose a first cylindrical tube for internally supporting the rotor core cup 800, so that the first arc-shaped plate 700 can better fit the inner wall of the rotor core cup 800, facilitating the clamping of the rotor core cup 800 by the first arc-shaped plate 700, thereby improving the stability of the rotor core cup 800 being clamped.

[0048] In some embodiments, referring to Figure 2 and Figure 3 , at the bottom end of each first arc-shaped plate 700 in the present application, a second arc-shaped plate 701 is arranged, and a plurality of second arc-shaped plates 701 enclose a second cylindrical tube for internally supporting the rotor core cup 800; wherein, the inner diameter of the second cylindrical tube is smaller than the inner diameter of the first cylindrical tube. That is to say, the first cylindrical tube enclosed by a plurality of first arc-shaped plates 700 can be used to clamp the rotor core cup 800 with a larger inner diameter, and the second cylindrical tube enclosed by a plurality of second arc-shaped plates 701 can be used to clamp the rotor core cup 800 with a smaller inner diameter. Therefore, the arrangement of the first arc-shaped plate 700 and the second arc-shaped plate 701 enables the paint stripping clamping device for the production of the coreless motor provided in the present application to be used to clamp rotor core cups 800 of multiple specifications, thereby improving the applicability of the paint stripping clamping device for the production of the coreless motor.

[0049] In some embodiments, referring to Figure 3 , the paint stripping clamping device in the present application further includes a limiting component 900 for limiting the lever 202; due to the elastic force of the elastic component 500, after the elastic component 500 is pressed down by one end of the lever 202, it will rebound upward. By limiting the lever 202 through the limiting component 900, the one end of the lever 202 is prevented from tilting up or pressing down, thereby improving the stability of the lever 202, and also preventing the one end of the lever 202 that can contact the elastic component 500 from tilting up due to the upward rebound of the elastic component 500, thereby improving the stability of the elastic component 500 during the paint stripping process of the rotor core cup 800.

[0050] In addition, referring to Figure 5, the limiting component 900 includes a limiting block 901, a vertical limiting rod 902, and a horizontal limiting rod 903; specifically, the limiting block 901 is arranged on the upper surface of the lower support plate 200, the bottom end of the vertical limiting rod 902 sequentially penetrates through the upper support plate 100, the limiting block 901, and the lower support plate 200 and can abut against the top of the lever 202, one end of the horizontal limiting rod 903 penetrates through the limiting block 901 and abuts against the vertical limiting rod 902 located inside the limiting block 901, lifting the end of the lever 202 away from the elastic component 500 upward, so that the end of the lever 202 directly above the elastic component 500 presses the elastic component 500 downward, causing the elastic component 500 to move downward and drive the plurality of clamping components 400 to close. At this time, the vertical limiting rod 902 is inserted into the limiting block 901, so that the bottom end of the vertical limiting rod 902 abuts against the top end of the lever 202, and then the horizontal limiting rod 903 is inserted into the limiting block 901, so that the horizontal limiting rod 903 abuts against the vertical limiting rod 902, thereby realizing the fixation of the lever 202 and enabling the plurality of clamping components 400 to be in a closed state. At this time, take the rotor core cup 800 that needs to be degreased, and make the bottom ends of the closed plurality of clamping components 400 extend into the interior of the rotor core cup 800, realizing the cross - carrying out of the experimental operations, thereby improving the experimental efficiency.

[0051] In some embodiments, referring to Figure 3 , one end of the lever 202 in contact with the top end of the elastic component 500 in this application is provided with an abutting head 2021. Among them, the abutting head 2021 is arranged downward, and the abutting head 2021 increases the contact area between the lever 202 and the top end of the elastic component 500. In this way, when the end of the lever 202 provided with the abutting head 2021 moves downward, the abutting head 2021 first contacts the top end of the elastic component 500, and the elastic component 500 is relatively easy to be pressed downward.

[0052] In some embodiments, referring to Figure 1 , Figure 2 and Figure 3 , the top end of the lead screw 300 in this application is provided with a handwheel 301. Among them, by rotating the handwheel 301, the rotation of the lead screw 300 is realized, which is convenient for operation, thereby improving the rotation efficiency of the lead screw 300.

[0053] Finally, it should be noted that the above - mentioned embodiments are only used to illustrate the technical solutions of this application, rather than to limit them; although this application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of this application.
