Description

Technical Field

[0001] This technical solution relates to the field of motor assembly equipment technology, specifically a barrel-type motor assembly equipment. Background Technology

[0002] A barrel motor is a type of motor with a cylindrical (barrel-shaped) housing design. Its compact structure helps to achieve efficient power transmission in a limited space.

[0003] Currently, in the assembly and production of barrel motors, the installation of coils, bases, rotors, bolts, and housings is all done manually by operators. Manual installation is time-consuming, labor-intensive, and costly, and the installation process is cumbersome, resulting in low efficiency and overall low production efficiency, which needs to be improved. Summary of the Invention

[0004] This technical solution aims to improve the low production efficiency caused by the manual operation of existing barrel motors by providing a barrel motor assembly equipment.

[0005] The purpose of this technical solution is achieved as follows:

[0006] A barrel-type motor assembly device for mounting coils, bases, rotors, and bolts onto a housing, including a frame and further comprising:

[0007] The station transfer device is installed on the frame and has several material carriers. The station transfer device is used to drive the material carriers to pass through each station in the circumferential direction.

[0008] A heating device, which is mounted on the frame, is used to heat the casing;

[0009] An assembly device, which is movably mounted on the frame and erected above the heating device, is used to heat-fit and press the heated housing onto the corresponding coil.

[0010] Pressing device 1 is movably mounted on the frame and erected above the material carrier, and is used to press and assemble the housing equipped with the base and rotor.

[0011] A bolt assembly device, which is mounted on the frame, is used to bolt the press-fitted housing and the base together;

[0012] Pressing device two, which is mounted on the frame and erected above the material carrier, is used to press the fan blades onto the housing bolted to the base; and

[0013] A feeding device, which is mounted on the frame, is used to remove and feed the casing equipped with fan blades.

[0014] Through the above technical solution, when a barrel-type motor assembly equipment is in normal use, the station transfer device first drives several material carriers on it to move circumferentially. At the initial first station, the coil is manually placed into the material carrier and the housing is manually placed into the heating device. The material carrier first passes through the second station, and the assembly device moves to the top of the heating device, grabs the housing that has expanded after heating, transfers it and precisely heat-presses it onto the coil of the material carrier. After turning around once, it returns to the initial station, inserts the base with the rotor, and transfers the housing with the coil onto the base. Pressing device one applies pressure to the housing with the pre-configured base and rotor at the second station to complete the press assembly; bolt assembly device at the third station automatically screws in the bolts to achieve a tight connection between the housing and the base; pressing device two at the fourth station presses the fan blades onto the assembled housing assembly; finally, the unloading device removes the fully assembled motor product from the carrier and unloads it. The entire process, through the orderly spatial layout and precise temporal coordination of each device, achieves automated assembly line operation from parts to finished products, thereby improving product production efficiency.

[0015] Preferably, the frame is slidably connected to a movable base, the frame is provided with a moving drive component, and the assembly device is disposed on the movable base. The assembly device includes:

[0016] An assembly frame, which is movably mounted on the movable base;

[0017] An assembly fixture is disposed at the lower end of the assembly frame; and

[0018] An assembly drive unit is mounted on the movable base and its output end is connected to the assembly frame. It is used to drive the assembly frame to move up and down. The movable drive unit is used to drive the movable base to move. The moving direction of the movable base is perpendicular to that of the assembly frame, so as to drive the assembly fixture to move the assembly housing and the coil.

[0019] Through the above technical solution, the moving drive component drives the moving seat to slide horizontally, and the assembly drive component drives the assembly frame to move up and down. Through the cooperation of the two vertical movements, the assembly fixture can operate flexibly in a two-dimensional plane. The assembly fixture can clamp the heated and expanded housing, thereby accurately fitting the hot housing into the coil and applying pressure to complete the heat fitting, simplifying the movement path of the mechanism and improving the assembly accuracy and efficiency of the housing and the coil.

[0020] Preferably, the movable seat is provided with the pressing device one, which includes:

[0021] The first pressing frame is movably mounted on the movable base;

[0022] A pressing block one is disposed at the lower end of the pressing frame one; and

[0023] A pressing drive component 1 is mounted on the movable base and its output end is connected to the pressing frame 1. It is used to drive the pressing frame 1 to move up and down, so as to drive the pressing block 1 to approach and press against the machine housing and the base.

[0024] Through the above technical solution, the moving drive component drives the moving seat to slide horizontally, and the pressing drive component drives the pressing frame to move up and down. Through the cooperation of the two vertical movements, the pressing block can operate flexibly in a two-dimensional plane, ensuring the stability of the pressing process and thus improving the pressing efficiency.

[0025] Preferably, the material carrier is provided with a pin holder, the pin holder having a insertion hole into which a pin for positioning through the through hole of the housing and the through hole of the base is inserted; the pressing frame is provided with a material release assembly, the material release assembly comprising:

[0026] The substrate is mounted on the pressing frame;

[0027] A stripping slider is slidably disposed on the substrate, and the substrate is provided with a stripping drive unit for driving the stripping slider to move;

[0028] A stripping clamp is movable relative to the stripping slider. The stripping slider is equipped with a second stripping drive component. The stripping clamp is connected to the output end below the second stripping drive component. The second stripping drive component drives the stripping clamp to move. The moving direction of the stripping clamp is perpendicular to that of the stripping slider. The stripping clamp grips the pin component through a clearance groove.

[0029] A push rod, which is fixed on the base plate and is confined within the relief groove, causes the push rod to push the pin along the relief groove to disengage and fall into the insertion hole when the stripping slider moves the stripping clamp.

[0030] Through the above technical solution, the four through holes of the housing are aligned and assembled with the four through holes of the base. The pin is manually removed from the insertion hole of the pin holder and inserted into one of the connecting holes. After the housing and the base are pressed together, the first ejector drive unit drives the ejector slider to move, so that the ejector clamp lifts the pin through the relief groove. The second ejector drive unit drives the ejector clamp to lift up, pull the pin out of the hole, and move it above the insertion hole for alignment. The push rod fixed on the base plate is embedded in the relief groove. As the ejector slider moves horizontally, the push rod pushes the pin along the relief groove. The pin leaves the relief groove and falls into the insertion hole for the next manual insertion. This realizes the automatic and non-destructive removal and return of the pin, improving the ejection accuracy and the continuity of operation.

[0031] Preferably, the bolt assembly device includes:

[0032] Frame;

[0033] A bolt feeding assembly includes a feeding frame, a feeding slider sliding on the feeding frame, and a feeding drive. The feeding frame has at least two pre-loading holes for preparing bolts. The feeding slider has pre-loading holes corresponding to the pre-loading holes. The feeding drive drives the feeding slider to move, thereby feeding bolts to the bolt mounting assembly via the pre-loading holes.

[0034] The bolt mounting assembly includes an assembly frame that slides on the frame body, a loading component set on the assembly frame, and a lifting drive component. At least four loading components are provided. The lifting drive component is used to drive the assembly frame to move up and down. The loading component picks up the bolts in the corresponding material preparation hole and tightens the bolts through the through hole of the housing into the through hole of the base.

[0035] Through the above technical solution, bolts are continuously fed from the conveying pipe to each material preparation hole 1. At least one bolt falls into the material preparation hole 2 each time. The feeding drive drives the feeding slider to move. The feeding slider carries the bolt to the assembly station. The lifting drive drives the assembly frame to use negative pressure to suck up the corresponding bolt. The feeding slider resets, the assembly frame descends, and the material preparation component drives the bolt to pass through the corresponding through holes of the machine housing and the base in sequence, and performs the tightening operation. By combining the intermittent feeding of the feeding slider with the multi-point synchronous assembly of the assembly frame, continuous and precise bolt feeding and efficient synchronous tightening are achieved, thereby improving assembly efficiency.

[0036] Preferably, the heating device includes:

[0037] An air blowing assembly, used to blow air into the interior of the housing;

[0038] Heating components, used to heat the interior of the casing; and

[0039] The transfer assembly includes a transfer frame mounted on the frame, a transfer slide mounted on the transfer frame, and a transfer clamp mounted on the transfer slide. The transfer frame is provided with a first transfer drive for driving the transfer slide to move, and the transfer slide is provided with a second transfer drive for driving the transfer clamp to move. The transfer clamp is perpendicular to the moving direction of the transfer slide and is used to clamp the blown casing to the heating assembly.

[0040] Through the above technical solution, the air blowing assembly cleans the inside of the housing, removing debris and impurities from the internal assembly surfaces. The first transfer drive component drives the transfer slide plate to slide horizontally, and the second transfer drive component drives the transfer clamp to move up and down. Through the cooperation of the two vertical movements, the transfer clamp can operate flexibly in a two-dimensional plane. The transfer clamp picks up the air-blown housing and places it into the heating assembly component. The heating assembly heats and expands the housing to facilitate the subsequent assembly of the housing and coil by the assembly device.

[0041] Preferably, the transfer frame is equipped with a positioning clamp, which is configured to clamp and position the housing in a manner corresponding to the heating component;

[0042] The frame is also equipped with a temperature detector, the detection end of which faces the heating assembly to detect the casing temperature.

[0043] With the above technical solution, when the housing is transported to the heating station, the positioning fixture clamps the housing to ensure that the housing maintains a precise positioning posture during the heating process; the temperature detector monitors and feeds back the temperature of the housing in real time, accurately controls the heating process parameters, and ensures that the temperature of the housing is in the optimal range when the heat-fitting is assembled, thereby improving the stability of the entire equipment operation and the assembly accuracy.

[0044] Preferably, the second pressing device includes:

[0045] The second pressing frame is movable and mounted on the frame.

[0046] Pressing block two, which is disposed at the lower end of the pressing frame two; and

[0047] The second pressing drive component is mounted on the frame and its output end is connected to the second pressing frame. It is used to drive the second pressing frame to move up and down, so as to move the second pressing block closer to and press against the fan blade and the housing.

[0048] Through the above technical solution, the second pressing drive component drives the second pressing frame to move up and down, so that the second pressing block presses the fan blade against the housing for assembly, ensuring that the fan blade and the housing are tightly pressed together.

[0049] Preferably, the feeding device includes:

[0050] A feeding rack, which is mounted on the frame;

[0051] The unloading seat is movably disposed at the top of the unloading frame. The unloading seat is provided with an unloading drive component, which is used to drive the unloading seat to move.

[0052] A feeding arm is movably mounted on the feeding base, which is equipped with a second feeding drive component. This second feeding drive component drives the feeding arm to move, and the direction of movement of the feeding arm is perpendicular to the direction of movement of the feeding base; and

[0053] The unloading clamp is located at the lower part of the unloading arm and is used to clamp the machine housing.

[0054] Through the above technical solution, the first feeding drive unit drives the feeding seat to move horizontally at the top of the feeding frame, and the second feeding drive unit drives the feeding arm to move vertically. The cooperation of the two vertical movements enables the feeding fixture to operate flexibly in a two-dimensional plane. The feeding fixture picks up the assembled motor housing and moves it to the feeding area to complete the placement of the housing, thereby improving the degree of automation and feeding efficiency.

[0055] Preferably, the workstation material transfer device includes:

[0056] A transfer table, which is rotatably connected to the frame;

[0057] The material carrier is disposed on the transfer platform. Several material carriers are circumferentially distributed around the rotation axis of the transfer platform. Each material carrier is divided into a first material carrier and a corresponding second material carrier. The first material carrier has a protruding positioning ring for engaging and positioning the machine housing. The second material carrier has a protruding positioning post one and a positioning post two for engaging and positioning the base.

[0058] A turntable drive unit, which is mounted on the frame, is used to drive the turntable to rotate.

[0059] Through the above technical solution, the turntable drive drives the material transfer table to rotate intermittently (90°) on the frame, so that several material carriers fixed on it pass through the heating, assembly, pressing, bolt assembly and unloading stations in sequence along the circumference. Each material carrier adopts a split design. The first material carrier is equipped with a positioning protrusion ring for the snap-fit ​​positioning of the machine housing, and the second material carrier achieves precise locking of the base through positioning post one and positioning post two, ensuring that the machine housing and the base maintain a stable relative position during the transfer process. This provides a precise benchmark for subsequent automated assembly, realizes the automatic transfer and precise docking of materials between each station, and improves the continuity of equipment operation and production efficiency.

[0060] The key and beneficial technical effects of this technical solution compared to existing technologies are:

[0061] This technical solution integrates heating devices, assembly devices, pressing devices, bolt assembly devices, and unloading devices along the circumference of the workstation transfer device to construct a coherent automated assembly system. Through multi-station collaboration and precise positioning, it ensures that components such as the base and rotor maintain stable alignment during transfer, reducing errors in manual assembly. It integrates the original scattered processes that relied on manual labor into continuous flow operations, improving assembly accuracy and production efficiency. Attached Figure Description

[0072] The specific implementation of this technical solution will be further described in detail below with reference to the accompanying drawings.

[0073] Example:

[0074] See Figure 1 A barrel-type motor assembly equipment for mounting coils, bases, rotors and bolts onto a machine housing includes a frame 1 and a station material transfer device 2, and also includes a heating device 3, an assembly device 4, a pressing device 1 5, a bolt assembly device 6, a pressing device 2 7 and a feeding device 8 arranged around the station material transfer device 2.

[0075] See Figure 2The workstation transfer device 2 includes a transfer table 21, several material carriers 22, and a turntable drive 23. The transfer table 21 is rotatably connected to the worktable surface of the frame 1, and its rotation axis is arranged vertically. There are four sets of material carriers 22, all mounted on the upper surface of the transfer table 21 and evenly distributed around its circumference. Adjacent material carriers 22 are spaced at a 90° angle. Each material carrier 22 is divided into a first material carrier 221 and a second material carrier 222. The first material carrier 221 is located at the... On the inner side of the two material seats 222, the first material seat 221 has a protruding positioning ring 2211 that matches the opening at the lower end of the machine housing. The machine housing is positioned by inserting into the positioning ring 2211. The second material seat 222 has a protruding positioning post 1 2221 and a positioning post 2222 for the base to be snapped into position. The turntable drive 23 is used to drive the turntable 21 to rotate intermittently around its vertical axis by 90° each time, so that each material seat 22 is driven to pass through various heating, assembly, pressing, bolt assembly and unloading stations in the circumferential direction.

[0076] See Figure 3 The heating device 3 includes an air blowing assembly 31, a heating assembly 32, and a transfer assembly 33. The air blowing assembly 31 is positioned at the front relative to the heating assembly 32. The machine housing is inserted into the air blowing assembly 31 by manual or automated robotic arm. The air blowing assembly 31 blows air into the interior of the machine housing through several air holes to remove debris and impurities. In this embodiment, a dust suction device can also be installed on the frame 1 to suck up the debris generated after air blowing. The heating assembly 32 typically includes a heating frame fixed to the frame 1, a heating drive component, and a heater. The heater is installed at the top of the heating frame. The heating drive component drives the heating frame to slide, thereby driving the heater through the through hole on the frame 1 into the interior of the machine housing to achieve the heating treatment of the workpiece.

[0077] The transfer assembly 33 includes a transfer frame 331, a transfer slide plate 332, and a transfer clamp 333. The transfer frame 331 is mounted on the frame 1. The transfer slide plate 332 is located on the side of the transfer frame 331 closest to the air blowing assembly 31 and the heating assembly 32. It is slidably connected to the transfer frame 331 via a guide rail slider structure, and its sliding direction is vertical. The transfer clamp 333 is located on the side of the transfer slide plate 332 opposite to the transfer frame 331. It is slidably connected to the transfer slide plate 332 via a guide rail slider structure, and its sliding direction is perpendicular to the transfer slide plate 332. Sliding direction; the transfer frame 331 is provided with a transfer drive component 171, the output end of which is connected to the transfer slide plate 332 for driving the vertical lifting of the transfer slide plate 332. The side of the transfer slide plate 332 is fixed with a transfer drive component 172, the output end of which is connected to the transfer clamp 333 for driving the horizontal movement of the transfer clamp 333. Thus, the transfer clamp 333 can move in coordination in two mutually perpendicular directions. The transfer clamp 333 grabs the machine casing after air cleaning through the clamping end at the lower end and transfers it to the heating component 32 for further processing.

[0078] The transfer frame 331 is equipped with a positioning clamp 18, which is installed on the transfer frame 331 and positioned corresponding to the position of the heating component 32. The positioning clamp 18 is used to clamp and position the housing, ensuring that the housing can maintain a precise positioning posture during the heating process when the heater is pushed out. The frame 1 is also equipped with a temperature detector 19, whose detection end faces the heating component 32, to monitor and provide feedback on the temperature of the housing in real time, accurately control the heating process parameters, and ensure that the housing temperature is within the optimal range required by the heat sleeve.

[0079] See Figure 4 The frame 1 is equipped with a movable seat 9, which is slidably connected to the top of the frame 1 via a guide rail slider structure, and the sliding direction is set horizontally. The frame 1 is equipped with a moving drive 10, the output end of which is connected to the movable seat 9 to drive the movable seat 9 to move horizontally. The assembly device 4 includes an assembly frame 41, an assembly fixture 42, and an assembly drive 43. The assembly frame 41 is slidably connected to the movable seat 9, and its moving direction is perpendicular to the sliding direction of the movable seat 9. The assembly fixture 42 is installed at the lower end of the assembly frame 41, and the assembly drive 43 is installed on the upper end face of the movable seat 9, and its output end is connected to the assembly frame 41 to drive the assembly frame 41 to move up and down, so that the assembly fixture 42 can move in two mutually perpendicular directions. A manual or automatic robotic arm places the coil on the first material seat 221 located in the first working position at the front. After the first material seat 221 rotates to the second working position on the side of the heating component 32, the assembly fixture 42 grabs the heated housing and transfers and heat-presses it onto the coil.

[0080] See Figure 5 and Figure 6The material carrier 22 is equipped with a pin holder 11, which is specifically installed on the second material carrier 222. The pin holder 11 has a socket 12, and a pin 111 can be inserted into the socket 12. During the second rotation of the transfer table 21, the housing and coil assembly return to the position of the first station. The base is placed on the second material carrier 222 by manual or automatic robotic arm, the rotor is placed in the base, and then the housing and coil assembly is taken out. The housing is installed on the base, and the four through holes on the periphery of the housing are aligned with the corresponding four through holes on the base. The pin 111 is taken out and inserted into one of the through holes of the housing and the base to achieve initial positioning.

[0081] The pressing device 5 is located in the second working position. It includes a pressing frame 51, a pressing block 52, and a pressing drive 53. The pressing frame 51 is movably mounted on the movable seat 9, and its moving direction is parallel to the moving direction of the assembly frame 41. The pressing block 52 is installed at the lower end of the pressing frame 51. The pressing drive 53 is installed on the upper end face of the movable seat 9, and its output end is connected to the pressing frame 51 for driving the pressing frame 51 to move up and down. When the base and the housing are combined and moved to the second working position in the second circle, the pressing block 52 is correspondingly mounted above the second material seat 222. The pressing drive 53 drives the pressing frame 51 to descend, so as to drive the pressing block 52 to press the housing and the base for further pressing and fixing.

[0082] The pressing frame 51 is provided with a stripping assembly 13, which includes a base plate 131, a stripping slider 132, a stripping clamp 133, and a push rod 134. The base plate 131 is fixedly installed at the lower end of the pressing frame 51. The stripping slider 132 is slidably connected to the upper end surface of the base plate 131 through a guide rail slider structure. Its sliding direction is set horizontally. A stripping drive unit 141 is installed on the rear side of the base plate 131. Its output end is connected to the stripping slider 132 and is used to drive the stripping slider 132 to move horizontally.

[0083] The stripping slider 132 is mounted on the side opposite to the stripping drive component 141, and the output end of the stripping slider 132 is connected to the stripping clamp 133. The stripping clamp 133 is located below the stripping drive component 142 and is used to drive the stripping clamp 133 to move. The moving direction is perpendicular to the sliding direction of the stripping slider 132, so that the stripping clamp 133 can move in two mutually perpendicular directions. The groove width of the clearance groove 15 is greater than the rod body of the pin 111 and smaller than the rod cap of the pin 111. The stripping clamp 133 has a clearance groove 15. The push rod 134 is fixed on the lower end face of the base plate 131. Its diameter is smaller than the groove width of the clearance groove 15, so that the push rod 134 passes through the clearance groove 15.

[0084] When the stripping clamp 133 lifts the pin 111 upward through the relief groove 15 and pulls it out, the stripping clamp 133 moves in the opposite direction to align with the insertion hole 12. As the stripping slider 132 moves horizontally, the push rod 134 pushes the pin along the relief groove 15. The pin disengages from the relief groove 15 and falls into the insertion hole 12, so that it can be inserted for the next time. This realizes the automatic and non-destructive removal and return of the pin, improving stripping accuracy and operation continuity.

[0085] See Figure 7 and Figure 8 The bolt assembly device 6 is located at the third station and includes a frame 61, a bolt feeding assembly 62, and a bolt mounting assembly 63. The frame 61 is installed on the rear side of the frame 1. Two sets of bolt feeding assemblies 62 are configured, located symmetrically on both sides of the bolt mounting assembly 63. Each bolt feeding assembly 62 includes a feeding frame 621, a feeding slider 622, and a feeding drive component 623. The feeding frame 621 is fixedly installed on the front side of the frame 61 and has two material preparation holes 161 for connecting a conveying pipe. The conveying pipe continuously feeds bolts into the material preparation holes 161. Two feeding sliders 622 are provided, and both sliders 622 are slidably connected to the lower part of the feeding frame 621 via a guide rail slider structure. Each feeding slider 622 has a second feeding hole 162, which corresponds one-to-one with the two first feeding holes 161. The diameter of the first feeding hole 161 is larger than the diameter of the bolt head, and the diameter of the second feeding hole 162 is larger than the diameter of the bolt shank but smaller than the diameter of the bolt head, so that the bolt can completely pass through the first feeding hole 161 and fall into the second feeding hole 162, with the bolt head abutting against the upper end face of the edge of the second feeding hole 162. Two feeding drive units 623 are installed on the feeding frame 621, which drive the two feeding sliders 622 to move to the bottom of the bolt mounting assembly 63. At this time, each of the two second feeding holes 162 carries two bolts, and the two bolt feeding assemblies 62 cooperate to feed out four bolts for subsequent bolt assembly.

[0086] The bolt mounting assembly 63 includes an assembly frame 631, loading components 632, and a lifting drive 633. The assembly frame 631 is slidably connected to the top of the frame 61, and its sliding direction is perpendicular to the sliding direction of the feeding slider 622. At least four loading components 632 are installed at the lower end of the assembly frame 631, and the four loading components 632 are arranged one-to-one with the four feeding sliders 622. The lifting drive 633 is installed on the top of the frame 1, and its output end is connected to the assembly frame 631 for driving the assembly frame 631 to move up and down. The lifting drive component 633 drives the assembly frame 631 to descend, thereby bringing the four loading components 632 closer to the four feeding sliders 622. The loading components 632 suck up the bolts in the corresponding material preparation holes 162 through negative pressure. Then the feeding sliders 622 move back, and the assembly frame 631 continues to descend. The four bolts pass through the four through holes that connect the machine housing and the base one by one. The loading components 632 rotate to perform the bolt tightening operation, screwing them into the threaded through holes in the base, thereby fixing the base and the machine housing with bolts.

[0087] See Figure 9 The pressing device 2 7 is located in the fourth working position. It includes a pressing frame 2 71, a pressing block 2 72, and a pressing drive component 2 73. The pressing frame 2 71 is movably mounted on the top of the frame 1, and its moving direction is parallel to the moving direction of the pressing frame 1 51. The pressing block 2 72 is installed at the lower end of the pressing frame 2 71.
