Description

Technical Field

[0001] This invention belongs to the field of hollow cup motor rotor processing equipment, and more specifically, relates to a carrier conveying mechanism for an automatic baking equipment for baking hollow cup motor rotors. Background Technology

[0002] With the development of technology and the rise in labor costs, production automation has become increasingly suitable for the current situation, and replacing manual production with fully automated production lines has become the choice of more and more manufacturing companies.

[0003] Coreless motors are widely used in military, aerospace, civilian electrical appliances, and industrial products due to their outstanding characteristics such as high energy conversion efficiency, rapid starting and braking, stable and reliable operation, and small speed fluctuation.

[0004] The conventional structure of a hollow cup motor rotor includes a spool, 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 spool covers the rotor frame, and the wire end on the spool is welded to the commutator segment of the commutator.

[0005] In existing technologies, before welding the rotor of a coreless motor, multiple adhesive application operations are required to bond the rotor components together for easier welding. Adhesive application is also necessary after welding to further secure the welded parts. Currently, the coreless motor rotor is typically placed on a fixture to allow the adhesive to dry naturally. This method is inefficient, and over time, the coils mounted on the rotor frame are prone to shifting due to their own weight, affecting subsequent welding of the coil ends to the commutator. If the fixture is placed in an oven for drying, it must be manually placed in and removed after a set drying time. Furthermore, because coreless motor rotors are generally small, small ovens are typically used, allowing only a small number of rotors to be dried at a time, all contributing to low production efficiency. Summary of the Invention

[0006] To address the aforementioned deficiencies or improvement needs of existing technologies, this invention provides a carrier conveying mechanism for an automatic baking device for baking hollow cup motor rotors. This mechanism allows the carrier to move up and down a chain conveyor belt via a carrier inlet / outlet channel, thereby baking the hollow cup motor rotor mounted on the carrier during the conveyor belt transport process. This automated feeding improves production efficiency.

After entering the heat insulation shell through one carrier entry and exit channel, it can be conveyed on the chain plate conveyor belt and baked inside the heat insulation shell while being conveyed, thereby drying the glue on the carrier.

[0019] 3) The carrier conveying mechanism of the automatic baking equipment for baking hollow cup motor rotor of the present invention has a chain with a serpentine segment, which greatly expands the baking path of the carrier and can fully bake the glue of the hollow cup motor rotor mounted on the carrier.

[0022] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. Furthermore, the technical features involved in the various embodiments of this invention described below can be combined with each other as long as they do not conflict with each other.

[0023] Reference Figures 1-4The carrier conveying mechanism for an automatic baking equipment used for baking hollow cup motor rotors includes a heat-insulating shell, a chain conveyor belt 15, a carrier inlet / outlet seat, a motor 1, and a gear transmission mechanism, wherein: The chain conveyor belt 15 is located inside the heat insulation shell and includes a chain 38 and chain plates 22. The chain 38 is arranged horizontally and is movably mounted on the heat insulation shell. The chain plates 22 are mounted on the chain 38. Several chain plates 22 are fixedly mounted on the top of the chain 38. The chain plates 22 are used to keep the chain conveyor belt 15 flat so that the carrier will not experience violent shaking when the chain conveyor belt 15 is running, which would cause the hollow cup motor rotor that needs to be baked to fall off the carrier.

[0024] The motor 1 is mounted on the heat insulation shell, and the motor housing of the motor 1 is located outside the heat insulation 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 geared motor, and an encoder 2 for obtaining the rotational speed of the motor 1 is mounted on the motor shaft of the motor 1.

[0025] There are two carrier entry / exit seats, each mounted on the side wall of the heat-insulating shell. Each carrier entry / exit seat has a carrier entry / exit channel, and each channel is located above the chain conveyor belt 15. If a carrier enters the heat-insulating shell through one channel, it exits through the other. The two channels are designated as the first and second channels.

[0026] Each of the vehicle entry / exit channels is arc-shaped to guide the movement of the vehicle along the arc-shaped vehicle entry / exit channel onto and off the chain.

[0027] Each of the vehicle entry / exit channels has one end close to the chain conveyor belt 15 and the other end away from the chain conveyor belt 15. Each of the vehicle entry / exit channels has a slide 45 for receiving the vehicle at the end away from the chain conveyor belt 15, so that the vehicle can slide on the slide 45. The slide 45 is relatively smooth, which facilitates the sliding of the vehicle on the slide and allows the next vehicle to be squeezed off the slide. The end of each vehicle entry / exit channel close to the chain conveyor belt 15 is vertically connected, so that the vehicle can slide onto the chain conveyor belt 15 via the slide 45 of one of the vehicle entry / exit channels for transportation, and the vehicle transported on the chain conveyor belt 15 can leave the chain conveyor belt 15 via the slide 45 of the vehicle entry / exit channel of another vehicle entry / exit channel. Therefore, the arc-shaped vehicle entry / exit channel has two arc-shaped inner sidewalls for guidance, and a portion of the bottom wall has a slide 45 to receive the vehicle. The portion near the chain conveyor belt 15 is open and vertically connected, with the inner sidewalls extending to the vertically connected portion for guidance, facilitating the movement of the vehicle onto the chain conveyor belt 15. Each vehicle entry / exit channel can hold a maximum of two vehicles at a time, one vehicle on the slide 45 of the vehicle entry / exit channel, and the other on the vertically connected portion of the vehicle entry / exit channel (the vehicle at the vertically connected portion has already fallen onto the chain conveyor belt 15). This facilitates the sequential pushing of vehicles onto the chain conveyor belt 15 or pushing them out of the slide of the vehicle entry / exit channel for transport.

[0028] Two notches 8 are provided on the side wall of the heat insulation shell, corresponding to the first vehicle access passage and the second vehicle access passage, to facilitate vehicle entry and exit.

[0029] Before entering the heat-insulating shell, a carrier equipped with a hollow cup motor rotor can be placed on an external track. An external feeding device, comprising a two-dimensional motion platform and a feeding hand driven by the platform, moves the foremost carrier on the external track horizontally to one of the slide rails 45. Subsequently, the feeding hand moves another carrier from the external track to slide rail 45, thus pushing the previous carrier on slide rail 45 onto the vertically connected portion of the carrier inlet / outlet channel. This vertically connected portion corresponds to the chain conveyor belt 15, allowing the carrier to land precisely on the chain conveyor belt 15. Since each carrier inlet / outlet channel is arc-shaped, the carrier can be guided along this arc-shaped channel to the vertically connected portion, where it slides precisely onto the chain conveyor belt 15. The carrier slides along the arc-shaped carrier entry / exit channel after leaving the chain conveyor belt 15. After leaving the chain conveyor belt 15, it slides onto the slide rail 45, where it can be picked up by a robotic arm, or it can be pushed off the slide rail 45 by the next carrier under inertia and transported onto the external conveyor belt. An electric heating device 100 is installed inside the heat-insulating shell to heat the hollow cup motor rotor mounted on the carrier during carrier transport.

[0030] Furthermore, the chain 38 has a serpentine section, a rounded transition section, and a straight connecting section, with each end of the serpentine section connected to the straight connecting section via a rounded transition section. The serpentine section greatly expands the baking path of the vehicle, allowing the adhesive on the hollow cup motor rotor mounted on the vehicle to be fully baked.

[0031] Furthermore, the gear transmission mechanism includes a driving gear 5, a rotating shaft 37, a driven gear 12, and a transmission gear 34. The driving gear 5 is mounted on the output shaft of the motor 1. The driven gear 12 meshes with the driving gear 5 and 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 meshes with one of the rounded transition sections of the chain 38. Therefore, by using a motor 1 as a power source and cooperating with the gear transmission mechanism, the entire plate chain conveyor belt can be driven to move to transport the carrier. Preferably, the invention also includes a passive gear 19 rotatably mounted on the heat-insulating shell and meshing with another rounded transition section. The passive gear 19 is not driven by a power source and rotates by meshing with the chain 38. The passive gear 19 and the transmission gear 34 each mesh with a rounded transition section. The rounded transition section corresponds to the turning point of the chain conveyor belt 15. A drive gear 34 and a driven gear 19 are installed at the turning point. The drive gear 34 and driven gear 19 cooperate to support the chain conveyor belt 15 and tension the chain 38. Preferably, the motor 1 is a geared motor with a gearbox 3 at the front and an encoder 2 at the rear. The gearbox 3 is fixedly installed to the mounting plate 4 via a flange, and the drive gear 5 is fixedly installed to the output shaft of the gearbox 3.

[0032] When motor 1 is powered on, it drives the drive gear 5 to rotate. The rotation of drive gear 5 drives the driven gear 12, which meshes with drive gear 5, to rotate. The rotation of driven gear 12 drives the rotating shaft 37 and the transmission gear 34 to rotate. The rotation of transmission gear 34 drives the chain 38 to move. The movement of chain 38 drives the entire chain conveyor belt 15 to move.

[0033] Furthermore, it also includes a bearing mounting base 35 and a bearing 33. The bearing mounting base 35 is fixedly mounted on the heat insulation shell. The rotating shaft 37 is mounted on the bearing mounting base 35 through the bearing 33. The rotating shaft 37 is provided with an external thread. A lock nut is connected to the external thread of the rotating shaft 37 and locks the rotating shaft 37 onto the inner ring of the bearing 33. The bearing 33 ensures the normal rotation of the rotating shaft 37.

[0034] Furthermore, multiple bearings 33 are provided and distributed along the vertical direction. The upper and lower ends of the bearing mounting base 35 are respectively provided with shims 36. Each shim 36 is fixed to the bearing mounting base 35 and abuts against one of the bearings 33 to limit the position of the bearings 33 at the upper end and the bearings 33 at the lower end of the bearing mounting base 33. The multiple bearings 33 cooperate with the shims 36 to ensure the reliability of the rotation of the rotating shaft 37.

[0035] The rotating shaft 37, the transmission gear 34, the driven gear 12, the bearing 33, and the bearing mounting base 35 are coaxially mounted.

[0036] Preferably, the heat insulation shell is provided with limiting strips 23 on both sides corresponding to the straight connecting section, and the limiting strips 23 are fixed to the heat insulation shell by connecting blocks 24.

[0037] Furthermore, the heat-insulating shell is provided with an inner limiting block 40 and an outer limiting block 39 on the inner and outer sides of each bend of the serpentine section, respectively. The inner limiting block 40 and the outer limiting block 39 are supported by a first support block 41 and a second support block 42, respectively. The first support block 41 and the second support block 42 are fixedly installed on the heat-insulating shell. The inner limiting block 40 and the outer limiting block 39 allow the chain 38 to bend into a serpentine shape and ensure the stability of the serpentine section, thereby enabling the chain 38 to reliably transport the vehicle.

[0038] The heat-insulating shell has a horizontal mounting surface 20, which can be used as a mounting base, such as a chain conveyor belt 15, gear transmission mechanism and other parts.

[0039] Furthermore, the chain tensioning mechanism includes a base 210, a moving block 212, a pad 211, a chain adjusting wheel 21, and an adjusting bolt 216, wherein: The base 210 is provided with a horizontal sliding groove 218, and a connecting block is provided at the bottom of the base 210. Preferably, the base 210 and the connecting block are integrally formed. The base 210 is provided with a connecting hole so as to connect the base 210 to an external mounting surface.

[0040] The movable block 212 is T-shaped, with 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. The first part 2121 extends beyond the slide groove 218 at each end along the width direction of 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. The movable block 212 and the movable rod 215 are preferably integrally formed.

[0041] The pad 211 is mounted on the first part 2121 of the movable block 212.

[0042] The centerline of the chain adjusting wheel 21 is vertically arranged, and the chain adjusting wheel 21 is rotatably mounted on the pad 211. The chain adjusting wheel 21 is preferably located above the pad 211. The chain adjusting wheel 21 has circumferentially evenly arranged external teeth for engaging with the gap of the chain 38. Thus, the chain adjusting wheel 21 and the chain 38 are engaged, and the normal movement of the chain 38 is not affected.

[0043] The adjusting bolt 216 includes an integrally formed bolt head and bolt shank. The bolt shank includes a threaded portion 217 and a smooth portion (the smooth portion has a cylindrical surface, which is smooth and without threads). 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 is in contact with the moving rod 215. The thread of the threaded portion 217 has a certain depth to drive the moving block to move. By turning the adjusting bolt 216, the moving block 212 can be moved. The movement of the moving block 212 drives the chain adjusting wheel 21 to move, thereby adjusting the position of the chain adjusting wheel 21. This allows the chain adjusting wheel 21 to press against the chain 38 to tighten the chain 38, preventing it from becoming loose and ensuring the normal operation of the chain 38's conveying function.

[0044] Furthermore, the bolt rod has at least two threaded portions 217, and a smooth portion is provided between the two threaded portions 217. Thus, the adjusting bolt 216 can drive the moving rod 215 to move whether it rotates clockwise or counterclockwise, thereby adjusting the tension of the chain 38.

[0045] Furthermore, the pad 211 includes a fixing block and a connecting rod mounted on the fixing block. The chain adjusting wheel 21 is mounted on the connecting rod via a bearing 219, thereby allowing the chain adjusting wheel 21 to rotate. The pad 211 keeps the chain adjusting wheel 21 at the same height as the chain 38.

[0046] Furthermore, one end of the connecting rod extends beyond the bearing 219, and a locking nut (not shown in the figure) is threaded onto the end of the connecting rod extending beyond the bearing 219. The locking nut locks the chain adjusting wheel 21 onto the outer ring of the bearing 219 to prevent the chain adjusting wheel 21 from shaking after prolonged use.

[0047] Furthermore, the first part 2121 of the movable block 212 is provided with a hollow hole, which can reduce the weight of the movable block 212 and make it easier to turn the adjusting bolt 216 to adjust the position of the chain adjusting wheel 21.

[0048] Furthermore, the movable rods 215 are arranged in pairs and symmetrically front to back, with one pair of movable rods 215 sandwiching the smooth portion. This makes the contact between the thread and the movable rods 215 more reliable, preventing one movable rod 215 from becoming unusable due to wear and thus affecting the normal adjustment of the chain adjusting wheel 21. The pair of movable rods 215 are mounted on the boss, so that the pair of movable rods 215 and the boss together form an inverted U-shaped block.

[0049] By turning the adjusting bolt 216, the moving rod 215 and the moving block 212 are pushed to move back and forth. The back and forth movement of the moving block 212 drives the chain adjusting wheel 21 to move back and forth, which is used to tighten or loosen the chain so that the chain is in a state that is neither too tight nor too loose.

[0050] Furthermore, the heat-insulating shell includes an inner heat-insulating layer, a middle heat-insulating layer, and an outer heat-insulating layer arranged from the inside out. 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 around the middle heat-insulating layer. The heat-insulating shell provides heat insulation in three layers, which can effectively prevent heat loss and insulate against heat, effectively preventing heat from being conducted to the motor 1 on the outside and damaging the motor 1.

[0051] The working process of this invention is as follows: When the motor 1 is powered on, it drives the drive gear 5 to rotate. The rotation of the drive gear 5 drives the driven gear 12, which meshes with the drive gear 5, to rotate. The rotation of the driven gear 12 drives the rotating shaft 37 and the transmission gear 34 to rotate. The rotation of 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.

[0052] After the electric heating device 100 inside the heat insulation shell is activated, the heat is isolated inside the heat insulation shell.

[0053] The carrier carrying the hollow cup motor rotor to be baked flows in through one carrier inlet / outlet channel and flows out through the other carrier inlet / outlet channel after baking. A temperature sensor 14 installed inside the heat-insulating shell senses the real-time temperature inside 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 conveyor belt 15.

[0054] Those skilled in the art will readily understand that the above description is merely 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 within the scope of protection of the present invention.
