Description

Technical Field

[0001] The invention belongs to the field of coreless motor rotor processing equipment, and more specifically, relates to a carrier conveying mechanism of an automatic baking device for baking coreless motor rotors. Background Art

[0002] With the development of science and technology and the increase in labor costs, production automation has become more and more in line with the current situation. Replacing manual production with fully automatic production lines has become the choice of more and more manufacturing companies.

[0003] Hollow cup motors are widely used in military, aerospace, civil appliances, industrial products and other fields because of their outstanding features such as high energy conversion efficiency, rapid starting and braking, stable and reliable operation, and small speed fluctuation.

[0004] The conventional structure of the coreless rotor includes a wire cup, a rotor frame, a rotor shaft and a commutator. The rotor frame is fixedly mounted on the rotor shaft, the commutator is mounted on the rotor frame, the wire cup is sleeved around the rotor frame, and the wire ends on the wire cup are welded to the commutator segments of the commutator.

[0005] In the prior art, before welding the coreless motor rotor, it is necessary to perform multiple glue dispensing operations on the coreless motor rotor to allow the various parts of the coreless motor rotor to stick together first, which is convenient for welding. Gluing is also required after welding to better fix the welded parts together. At present, the coreless motor rotor is generally placed on the tooling and the glue is allowed to dry naturally, which makes the production efficiency low. Moreover, after a long time, the wire cup on the rotor frame is also easy to fall down and shift under its own weight, affecting the subsequent welding of the wire end of the wire cup on the commutator. If the carrier is placed in an oven for drying, the carrier needs to be manually placed in the oven and taken out after the set drying time. Moreover, since the volume of the coreless motor rotor is generally small, a small oven is generally used, and only a small number of coreless motor rotors can be dried at a time. All these make the production efficiency low. Summary of the invention

[0035] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0036] Reference Figure 1 to Figure 4, a carrier conveying mechanism of an automatic baking device for baking a hollow cup motor rotor, comprising a heat-insulating shell, a chain plate conveyor belt 15, a carrier entry and exit seat, a motor 1 and a gear transmission mechanism, wherein:

[0037] The chain plate conveyor belt 15 is located inside the heat-insulating shell and includes a chain 38 and a chain plate 22. The chain 38 is arranged horizontally and movably mounted on the heat-insulating shell. The chain plate 22 is mounted on the chain 38. A plurality of chain plates 22 are fixedly mounted on the chain 38. The chain plates 22 are used to keep the chain plate conveyor belt 15 flat so that when the chain plate conveyor belt 15 is running, the carrier will not be violently shaken to cause the hollow cup motor rotor to be baked to fall from the carrier.

[0038] The motor 1 is mounted on the heat-insulating shell, and the motor 1 shell of the motor 1 is located outside the heat-insulating shell. The motor 1 is connected to the chain 38 through the gear transmission mechanism to drive the chain 38 to move; the motor 1 is preferably a reduction motor, and an encoder 2 for obtaining the rotational speed of the motor 1 is installed on the motor shaft of the motor 1.

[0039] There are two carrier access seats, each of which is installed on the side wall of the heat-insulating shell, each of which is provided with a carrier access channel, and each of which is located above the chain plate conveyor belt 15; if a carrier enters the heat-insulating shell from one of the carrier access channels, it will exit the heat-insulating shell from the other carrier access channel. The two carrier access channels are the first carrier access channel and the second carrier access channel.

[0040] Each of the carrier access channels is arc-shaped to guide the movement of the carrier, and the carrier moves onto the chain and leaves the chain along the arc-shaped carrier access channel.

[0041] One end of each of the carrier entrance and exit channels is close to the chain-plate conveyor belt 15 and the other end is away from the chain-plate conveyor belt 15. The end of each of the carrier entrance and exit channels away from the chain-plate conveyor belt 15 is respectively arranged with a slide 45 for receiving the carrier so that the carrier can slide on the slide 45. The slide 45 is relatively smooth, which facilitates the sliding of the carrier on the slide and can be squeezed off the slide by the next carrier; the end of each of the carrier entrance and exit channels close to the chain-plate conveyor belt 15 is through-connected from top to bottom, so that the carrier can slide onto the chain-plate conveyor belt 15 through the slide 45 of one of the carrier entrance and exit channels for transportation, and the carrier transported on the chain-plate conveyor belt 15 can leave the chain 38 through the slide 45 of the carrier entrance and exit channel of another carrier entrance and exit seat. Therefore, the arc-shaped carrier access channel has two arc-shaped inner side walls for guidance, and a part of the bottom wall has a slide 45 to receive the carrier, and a part close to the chain plate conveyor belt 15 is empty and through-through, and the inner side wall extends to the through-through part for guidance, so as to facilitate the movement of the carrier onto the chain plate conveyor belt 15. There can be at most two carriers in each carrier access channel at a time, one of which is on the slide 45 of the carrier access channel, and the other is on the through-through part of the carrier access channel (the carrier at the through-through part has also fallen onto the chain plate conveyor belt 15), so that it is convenient to squeeze the carriers one by one onto the chain plate conveyor belt 15, or squeeze out of the slide of the carrier access channel to be transported away.

[0042] Two notches 8 are provided on the side wall of the heat-insulating shell, corresponding to the first carrier access channel and the second carrier access channel, so as to facilitate the access of the carriers.

[0043] Before entering the heat-insulating housing, a carrier carrying a coreless motor rotor can be placed on an external track, and the carrier on the external track can be pushed onto one of the slideways 45 by an external material-pushing device, wherein the material-pushing device includes a two-dimensional motion platform and a material-pushing hand driven by the two-dimensional motion platform, and the two-dimensional motion platform drives the material-pushing hand to move horizontally to push the frontmost carrier on the external track onto one of the slideways 45; thereafter, the material-pushing hand pushes another carrier on the external track onto the slideway 45, thereby squeezing the previous carrier on the slideway 45 to the vertically connected part of the carrier access channel, which corresponds to the chain plate conveyor belt 15, and the carrier will just fall on the chain plate conveyor belt 15. Since each of the carrier access channels is arc-shaped, the carrier can be guided along the arc-shaped carrier access channel, move to the vertically connected part of the carrier access channel, and just slide onto the chain plate conveyor belt 15. The carrier also slides along the arc-shaped carrier access channel when leaving the chain plate conveyor belt 15, and slides onto the slideway 45 after leaving the chain plate conveyor belt 15, and then can be taken away by the robot, or moved by the next carrier under inertia from the slideway 45 and squeezed onto the external conveyor belt for transportation. The electric heating device 100 is arranged in the heat-insulating shell, so that the hollow cup motor rotor carried by the carrier can be heated when the carrier is transported.

[0044] Furthermore, the chain 38 has a serpentine section, a rounded transition section and a straight connecting section, and the straight connecting section is connected to each end of the serpentine section through a rounded transition section. The serpentine section greatly expands the path of carrier baking, so that the glue of the hollow cup motor rotor carried on the carrier can be fully baked.

[0045] Further, the gear transmission mechanism includes a driving gear 5, a rotating shaft 37, a driven gear 12 and a transmission gear 34, wherein the driving gear 5 is mounted on the output shaft of the motor 1, the driven gear 12 is meshed with the driving gear 5, the driven gear 12 is mounted on the rotating shaft 37, the rotating shaft 37 is vertically arranged and rotatably mounted on the heat-insulating shell, the transmission gear 34 is fixedly mounted on the rotating shaft 37, and the transmission gear 34 is meshed with one of the arc transition sections of the chain 38. Therefore, by using a motor 1 as a power source, in conjunction with a gear transmission mechanism, the entire plate chain conveyor belt can be driven to move to transport the carrier. Preferably, the present invention also includes a passive gear 19 rotatably mounted on the heat-insulating shell and meshed with another arc transition section. The passive gear 19 is driven without a power source and rotates by meshing with the chain 38, and the passive gear 19 and the transmission gear 34 are respectively meshed with one arc transition section. The arc transition section is equivalent to the transition point of the chain plate conveyor belt 15. The driving gear 34 and the passive gear 19 are arranged at the turning part. The driving gear 34 and the passive gear 19 cooperate to support the chain plate conveyor belt 15 and tighten the chain 38. Preferably, the motor 1 is a reduction motor, with a gear box 3 at the front end and an encoder 2 at the rear end. The gear box 3 is fixedly installed with the mounting plate 4 through a flange, and the driving gear 5 is fixedly installed with the output shaft of the gear box 3.

[0046] After the motor 1 is powered on, it drives the driving gear 5 to rotate. The driving gear 5 drives the driven gear 12 meshing with the driving gear 5 to rotate. The driven gear 12 drives the rotating shaft 37 and the transmission gear 34 to rotate. The transmission gear 34 drives the chain 38 to move. The movement of the chain 38 drives the entire chain conveyor belt 15 to move.

[0047] Furthermore, it also includes a bearing mounting seat 35 and a bearing 33. The bearing mounting seat 35 is fixedly mounted on the heat-insulating shell. The rotating shaft 37 is mounted on the bearing mounting seat 35 through the bearing 33. An external thread is set on the rotating shaft 37. The locking nut is connected to the external thread of the rotating shaft 37 and locks the rotating shaft 37 on the inner ring of the bearing 33. The bearing 33 ensures the normal rotation of the rotating shaft 37.

[0048] Furthermore, a plurality of bearings 33 are provided, and they are distributed along the vertical direction. Gaskets 36 are provided at the upper and lower ends of the bearing mounting seat 35, respectively. Each gasket 36 is fixed to the bearing mounting seat 35 and abuts against one of the bearings 33, respectively, so as to limit the position of the bearing 33 at the upper end of the bearing 33 seat and the bearing 33 at the lower end of the bearing 33 seat. The plurality of bearings 33 cooperate with the gaskets 36 to ensure the reliability of the rotation of the rotating shaft 37.

[0049] The rotating shaft 37, the transmission gear 34, the driven gear 12, the bearing 33, and the bearing mounting seat 35 are coaxially mounted.

[0050] Preferably, the heat-insulating outer shell is provided with limit bars 23 at positions corresponding to both sides of the straight connecting section, and the limit bars 23 are fixed to the heat-insulating outer shell through connecting blocks 24 .

[0051] Furthermore, the heat-insulating outer shell is provided with inner limit blocks 40 and outer limit blocks 39 on the inner and outer sides of each turning part of the serpentine section, respectively. The inner limit blocks 40 and outer limit blocks 39 are supported by first support blocks 41 and second support blocks 42, respectively. The first support blocks 41 and second support blocks 42 are respectively fixedly mounted on the heat-insulating outer shell. The inner limit blocks 40 and outer limit blocks 39 can make the chain 38 bend into a serpentine shape and ensure the stability of the serpentine section, so that the chain 38 can reliably transport the carrier.

[0052] A horizontal mounting surface 20 is provided on the heat-insulating housing, which serves as a mounting base, for example, a mounting base for parts such as a chain plate conveyor belt 15 and a gear transmission mechanism.

[0053] Further, the chain tensioning mechanism includes a base 210, a moving block 212, a cushion block 211, a chain adjusting wheel 21 and an adjusting bolt 216, wherein:

[0054] The base 210 is provided with a horizontal slide groove 218, and a connection block is provided at the bottom of the base 210. Preferably, the base 210 and the connection block are integrally formed. The base 210 is provided with a connection hole so as to connect the base 210 to an external mounting surface.

[0055] The movable block 212 is T-shaped as a whole, and has a structure that is larger at the top and smaller at the bottom. It has an integrally formed first part 2121 and a second part 2122. Each end of the first part 2121 along the width direction of the slide groove 218 exceeds the slide groove 218, so that the first part 2121 of the movable block 212 is placed on the top of the base 210; the second part 2122 of the movable block 212 extends into the slide groove 218 of the base 210 so as to slide along the slide groove 218. The slide groove 218 serves as a guide groove for the movement of the movable block 212, and can guide the movement of the second part 2122. A movable rod 215 is provided at the bottom of the movable block 212, and the movable block 212 and the movable rod 215 are preferably integrally formed.

[0056] The cushion block 211 is mounted on the first portion 2121 of the moving block 212 .

[0057] The center line of the chain adjusting wheel 21 is vertically arranged, and the chain adjusting wheel 21 is rotatably mounted on the cushion block 211. The chain adjusting wheel 21 is preferably located above the cushion block 211. The chain adjusting wheel 21 has external teeth evenly arranged circumferentially for inserting into the gap of the chain 38. Then, the chain adjusting wheel 21 is meshed with the chain 38 and does not affect the normal movement of the chain 38.

[0058] The adjusting bolt 216 includes an integrally formed bolt head and a bolt rod, the bolt rod includes a threaded portion 217 and a smooth portion (the smooth portion has a cylindrical surface, the cylindrical surface is smooth and has no threads), and the thread of the threaded portion 217 protrudes relative to the smooth portion, the threaded portion 217 is threadedly connected to the connecting block, the smooth surface of the smooth portion abuts against the moving rod 215, and the thread of the threaded portion 217 has a certain depth to drive the moving block to move. By screwing the adjusting bolt 216, the moving block 212 can be moved, and the movement of the moving block 212 drives the chain adjusting wheel 21 to move, so that the position of the chain adjusting wheel 21 can be adjusted, so that the chain adjusting wheel 21 is pressed on the chain 38 to tighten the chain 38, prevent the chain 38 from becoming loose, and ensure the normal conveying work of the chain 38.

[0059] Furthermore, the bolt rod is provided with at least two threaded portions 217 , and a smooth portion is provided between the two threaded portions 217 . Then, the adjusting bolt 216 can drive the moving rod 215 to move regardless of forward or reverse rotation, thereby adjusting the tightness of the chain 38 .

[0060] Further, the cushion block 211 includes a fixed block and a connecting rod mounted on the fixed block, and the chain adjusting wheel 21 is mounted on the connecting rod through a bearing 219, so that the chain adjusting wheel 21 can rotate. The cushion block 211 keeps the chain adjusting wheel 21 and the chain 38 at the same height.

[0061] Furthermore, one end of the connecting rod protrudes out of the bearing 219, and the end of the connecting rod protruding out of the bearing 219 is threadedly connected with a locking nut (not shown in the figure), and the locking nut locks the chain adjusting wheel 21 on the outer ring of the bearing 219 to prevent the chain adjusting wheel 21 from shaking after a long period of use.

[0062] Furthermore, a hollow hole is provided on the first portion 2121 of the moving block 212 , which can reduce the weight of the moving block 212 and make it easier to turn the adjusting bolt 216 to adjust the position of the chain adjusting wheel 21 .

[0063] Furthermore, the moving rods 215 are arranged in pairs and are symmetrically arranged front and back, and the pair of moving rods 215 sandwich the smooth surface portion, so that the contact between the thread and the moving rod 215 is more reliable, preventing one moving rod 215 from being unable to be pushed by the adjustment bolt 216 after being worn, thereby affecting the normal adjustment of the chain adjustment wheel 21. The pair of moving rods 215 are arranged on the boss, so that the pair of moving rods 215 and the boss together form an inverted U-shaped block.

[0064] By screwing the adjusting bolt 216, the moving rod 215 and the moving block 212 are pushed to move forward and backward. The forward and backward movement of the moving block 212 drives the chain adjusting wheel 21 to move forward and backward, which is used to tighten or loosen the chain so that the chain is neither too tight nor too loose.

[0065] Furthermore, the heat-insulating outer shell includes an inner heat-insulating layer, a middle heat-insulating layer and an outer heat-insulating layer arranged from the inside to the outside, the inner heat-insulating layer and the outer heat-insulating layer are fixedly connected, and the inner heat-insulating layer and the outer heat-insulating layer cooperate to wrap the middle heat-insulating layer. The heat-insulating outer shell is divided into three layers for heat insulation, which can effectively prevent heat loss and isolate heat, and effectively prevent heat from being conducted to the motor 1 outside and damaging the motor 1.

[0066] The working process of the present invention is as follows:

[0067] After the motor 1 is powered on, it drives the driving gear 5 to rotate. The driving gear 5 drives the driven gear 12 meshing with the driving gear 5 to rotate. The driven gear 12 drives the rotating shaft 37 and the transmission gear 34 to rotate. The transmission gear 34 drives the chain 38 to move. The movement of the chain 38 drives the entire chain plate conveyor belt 15 to move.

[0068] After the electric heating device 100 in the heat-insulating shell is in operation, the heat is isolated in the heat-insulating shell.

[0069] The carrier carrying the coreless motor rotor to be baked flows in from one of the carrier access channels and flows out from the other carrier access channel after being baked. The temperature sensor 14 installed in the heat-insulating shell senses the real-time temperature in the oven and displays it on a display screen outside the heat-insulating shell. If the temperature is higher or lower than the required temperature range, the desired effect can be achieved by adjusting the electric heating device or by adjusting the running speed of the chain plate conveyor belt 15.

[0070] It will be easily understood by those skilled in the art that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
