Description

Technical Field

[0001] The invention relates to tooling, in particular to a tubular motor assembly device. Background Art

[0002] Rolling shutter doors and windows are usually installed with tubular motors, which drive the opening and closing of doors and windows, greatly facilitating people's lives and therefore have been widely used.

[0003] The tubular motor installation process involves using a push rod to push the travel mechanism, motor, reduction gear, and brake components, all assembled in sequence, from one end of the outer tube into the inner tube. Traditionally, installation is done manually on a horizontal workbench. After positioning the motor horizontally, a rocker arm and reduction gear combination are used to increase thrust, pushing the motor assembly into the outer tube to complete the assembly.

[0004] There are also some automated devices that push the motor assembly into the outer tube through hydraulic actuators. For example, Chinese patent application number 202320168646.5 discloses a pressing device for assembling a tubular motor, which includes: a base; a guide drive device, which includes a positioning block provided on the base, a slide provided on the positioning block, a guide block slidingly provided on the slide, and a moving actuator that drives the guide block to move along the slide; a pressing positioning device, which includes a fixed base provided on the base, a pressure block located above the fixed base, and a pressing actuator that drives the pressure block to press against the fixed base, the fixed base being provided with a first pressing groove, the pressure block being provided with a second pressing groove that cooperates with the first pressing groove, and the first pressing groove and the slide groove being distributed in sequence along the length direction of the tubular motor.

[0005] Due to the limitations of the slide groove and the pressing groove, the above-mentioned pressing device can only be used to assemble tubular motors of one diameter. Therefore, when facing the assembly needs of tubular motors of different diameters, only devices of different sizes can be used, which increases costs and reduces assembly efficiency. In addition, for tubular motors of different lengths, the position of the positioning block needs to be manually adjusted, which also leads to low assembly efficiency. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a tubular motor assembly device to improve versatility and reduce costs in view of the deficiencies in the above-mentioned prior art.

[0007] The technical solution adopted by the present invention to solve the above technical problems is: a tubular motor assembly device, comprising an operating table, an outer tube base and a first linear drive mechanism, wherein the motor assembly and the outer tube of the tubular motor to be assembled are arranged between the outer tube base and the first linear drive mechanism, and the device is characterized in that:

[0008] The operating table is provided with a sliding table, and a first sliding groove and a second sliding groove are formed on the sliding table. The first sliding groove and the second sliding groove extend respectively along the axial direction of the tubular motor to be assembled, and the two sliding grooves are arranged side by side along the width direction of the operating table. The width direction of the operating table is perpendicular to the axial direction of the tubular motor to be assembled. The width of the first sliding groove is greater than the width of the second sliding groove. The motor assembly can be placed in the adapted first sliding groove or the second sliding groove. The outer tube is supported between the outer tube base and the end of the motor assembly.

[0009] The operating table is also provided with a first push block and a second push block. The first push block can slide along the first slide groove and is adapted in size. The second push block can slide along the second slide groove and is adapted in size. The first linear drive mechanism selectively drives the first push block and the second push block to push the motor combination in the corresponding slide groove into the outer tube.

[0010] By providing first and second chutes of different sizes, and push blocks respectively matching the chutes, chutes and corresponding push blocks of matching sizes can be selected according to the size of the tubular motor currently to be assembled, without the need to place tubular motors of different sizes in different assembly devices, thereby improving the versatility of the assembly device, greatly reducing costs, and facilitating operator operation and improving production efficiency.

[0011] Furthermore, in order to facilitate the pushing block to push the motor assembly into the outer tube and make the ends flush, the first pushing block and the second pushing block have the same structure, each pushing block includes a first pushing part and a second pushing part, and the first pushing part and the second pushing part together constitute a blind hole for inserting the output shaft of the power supply combination, the first pushing part is used to abut against the outer tube, and the second pushing part is used to abut against the end of the motor assembly.

[0012] Furthermore, in order to facilitate the first linear drive mechanism to selectively connect and disengage with one of the push blocks, the first linear drive mechanism includes an output end and a coupling for selectively connecting the output end with one of the push blocks, a connecting groove is formed at the end of each push block that cooperates with the coupling, the connecting groove is recessed from a side of each push block close to the other push block to a side away from the other push block, and the connecting groove passes through the end surface facing the output end, the connecting groove includes a first groove portion and a second groove portion that are interconnected, the size of the second groove portion is larger than the first groove portion, and the connecting groove is T-shaped along the axial cross-section of the tubular motor, and the first groove portion is located close to the output end, and the second groove portion is located away from the output end, and the second groove portion and the blind hole are spaced apart in each push block;

[0013] The coupling includes a first connecting portion, a second connecting portion and a third connecting portion which are coaxially arranged in sequence, wherein the first connecting portion is connected to the output end, the second connecting portion passes through the connecting groove, and the third connecting portion constitutes a stop portion and is axially confined within the second groove portion.

[0014] In order to limit the sliding track of the push block, each push block has a positioning block at the bottom, which cooperates with the second positioning groove formed in the corresponding slide groove. The second positioning groove is formed at the bottom of the corresponding slide groove and is located on both sides in the width direction.

[0015] In order to stably support the motor assembly, limit the movement trajectory of the motor assembly when it is pushed, and prevent it from rotating, each slide groove is formed by being recessed from the side of the sliding platform away from the operating platform toward the operating platform, and each slide groove has supporting walls arranged opposite to each other in the width direction, and the two supporting walls gradually approach each other from the side away from the operating platform toward the operating platform, and the motor assembly is supported on the supporting walls;

[0016] A first positioning groove is further formed at the corresponding position of the sliding platform and each sliding groove. A protrusion is provided on the peripheral wall of the end portion of the motor assembly, and the protrusion can be inserted into the first positioning groove.

[0017] In order to enable the outer tube base to adapt to outer tubes of different diameters and lengths, the outer tube base and the corresponding ends of the outer tube are formed with a first step portion and a second step portion, both of which are annular. The first step portion is farther away from the motor assembly than the second step portion, and the size of the first step portion is larger than the second step portion.

[0018] In order to prevent the outer tube from being ejected due to force during assembly, the assembly device further comprises a block capable of linearly reciprocating along a direction perpendicular to the axial direction. The block can be moved to the side of the outer tube away from the operating table to block the outer tube.

[0019] Furthermore, a screwdriver is provided at a position on the operating table corresponding to the end of the outer tube facing the motor assembly, and the feeding direction of the screwdriver is perpendicular to the axial direction of the tubular motor. A first screw hole is formed on the circumferential wall of the end of the motor assembly facing the corresponding push block, and a second screw hole is formed on the circumferential wall of the end of the outer tube facing the motor assembly. The angles of the first screw hole and the second screw hole correspond to each other, and the screwdriver can also move back and forth in a straight line in a direction perpendicular to the axial direction to approach or move away from the outer tube, thereby further fixing the motor assembly and the outer tube.

[0020] Furthermore, a support base is fixedly provided on the operating table, and the end of the outer tube facing the motor assembly is supported on the support base. The support base or the operating table is also provided with an elastic member, and a slot is formed on the end of the outer tube facing the motor assembly. The elastic member is rotatably provided on the support base or the operating table, and the direction in which the rotation axis of the elastic member extends is in the same direction as the axial direction of the tubular motor. The elastic member has a first end and a second end located at opposite ends of the rotation center. The first end constitutes a snap portion that can be snapped into the slot, and the elastic member maintains the tendency of the snap portion to snap into the slot. This automatically locks the outer tube, ensuring that the second screw hole of the outer tube is aligned with the screwdriver bit, without the need for additional positioning and operation.

[0021] Furthermore, in order to reduce the force required when placing the tubular motor, the operating table is placed in a state inclined with respect to the vertical direction, and the first pushing block and the second pushing block are arranged near the upper end of the operating table.

[0022] Compared with the prior art, the advantages of the present invention are that: by providing first chutes and second chutes of different sizes, and push blocks respectively matching the chutes, chutes and corresponding push blocks of matching sizes can be selected according to the size of the tubular motor currently to be assembled, without the need to place tubular motors of different sizes in different assembly devices, thereby improving the versatility of the assembly device, greatly reducing costs, and facilitating operator operation and improving production efficiency.

[0038] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions.

[0039] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Since the embodiments disclosed in the present invention can be set in different directions, these terms indicating directions are only for illustration and should not be regarded as limitations. For example, "up" and "down" are not necessarily limited to directions opposite to or consistent with the direction of gravity. In addition, features defined as "first" and "second" may explicitly or implicitly include one or more of such features.

[0040] See also Figures 1 to 11 A tubular motor assembly device includes an operating table 1, a first push block 21, a second push block 22, a first slide groove 31, a second slide groove 32, an outer tube base 4, a screwdriver 5 and a first linear drive mechanism 6.

[0041] The operating table 1 is in the form of a platform. When actually working, it is placed in a state of being tilted from the vertical direction. Figure 1 As shown in ( Figure 1 (This is merely an example; a consistent tilt angle is not strictly required.) Since tubular motors are generally heavy, this tilting arrangement facilitates their placement on the operating table 1. The operating table 1 is elongated, providing ample space for the tubular motor to be assembled. The tubular motor to be assembled comprises two components: a motor assembly 100 and an outer tube 200. The motor assembly 100 typically includes a travel device, a motor core, a speed reduction mechanism, a brake mechanism, and other components. Both the motor assembly 100 and the outer tube 200 are similar to those of the prior art.

[0042] The first push block 21 and the second push block 22 are positioned near the upper end of the operating platform 1. A first linear drive mechanism 6 is disposed above the operating platform 1 and can be a commonly used electric push rod, pneumatic cylinder, or hydraulic cylinder. Its output end 61 extends to the upper end of the operating platform 1 and can be extended and retracted along the length of the operating platform 1. The length of the operating platform 1 corresponds to the axial direction X of the tubular motor.

[0043] The first push block 21 and the second push block 22 have the same structure and are arranged along the width direction of the operating table 1 (the width direction refers to the width direction of the operating table 1). Figure 4The first and second pushing portions 211, 212 are arranged side by side (in the left and right directions) and are perpendicular to the axial direction X of the tubular motor. Each pushing block includes a first pushing portion 211 and a second pushing portion 212, which are preferably integrally formed and combined into a generally hollow cylindrical shape. The first pushing portion 211 is located on the side away from the operating table 1, and the second pushing portion 212 is located on the side close to the operating table 1. The blind hole 213 in the middle is for the output shaft 101 of the motor assembly 100 of the tubular motor to pass through. The cross-sections of the first and second pushing portions 211, 212 (the cross-sections perpendicular to the axial direction X of the tubular motor) are both fan-shaped, with the same inner diameter. The central angles of the first and second pushing portions 211, 212 are not limited, as long as they have two parts. The outer diameter of the first pushing portion 211 is larger than the outer diameter of the second pushing portion 212, and the outer diameter of the first pushing portion 211 is greater than the outer diameter of the tubular motor outer tube 200, which is greater than the outer diameter of the motor assembly 100. The outer diameter of the second pushing portion 212 is substantially the same as the outer diameter of the motor assembly 100, so that it can abut against the end of the motor assembly 100 and push the motor assembly 100. The outer diameter of the first pushing portion 211 of the second pushing block 22 is smaller than the outer diameter of the first pushing portion 211 of the first pushing block 21, and the outer diameter of the second pushing portion 212 of the second pushing block 22 is smaller than the outer diameter of the second pushing portion 212 of the first pushing portion 21. Thus, the first pushing block 21 and the second pushing block 22 can adapt to tubular motors of different diameters.

[0044] The motor assembly 100 of the tubular motor is placed close to the first push block 21 (or the second push block 22 ), while the outer tube 200 is placed at one end of the motor assembly 100 away from the corresponding push block.

[0045] The surface of the operating table 1 is provided with a sliding table 33, and the sliding table 33 and the above-mentioned first push block 21 and second push block 22 are located on the same side surface of the operating table 1. The sliding table 33 is recessed away from the surface of the operating table 1 to form the above-mentioned first slide groove 31 and second slide groove 32. The first slide groove 31 and the second slide groove 32 extend respectively along the axial direction X of the tubular motor, and the first slide groove 31 and the second slide groove 32 are arranged side by side along the width direction of the operating table 1. The first slide groove 31 corresponds to the first push block 21, and the second slide groove 32 corresponds to the second push block 22. The correspondence here means that the positions correspond respectively, and the width of each slide groove also corresponds to the outer diameter of the corresponding push block. That is, in this embodiment, the width of the first slide groove 31 is greater than the width of the second slide groove 32. The end portion of the first push block 21 facing the motor assembly 100 is located in the first slide groove 31, and the end portion of the second push block 22 facing the motor assembly 100 is located in the second slide groove 32. The motor assembly 100 is placed in the first slide groove 31 or the second slide groove 32, as shown Figure 1 As shown, the motor assembly 100 of the tubular motor with a diameter of 45 mm to be assembled is placed in the first slide groove 31, and as shown in FIG. Figure 15 As shown, the motor assembly 100 of a tubular motor with a diameter of 35 mm to be assembled is placed in the second sliding groove 32 .

[0046] The first chute 31 and the second chute 32 have the same structure. Each chute has support walls 311 arranged opposite each other in the width direction. The two support walls 311 gradually approach each other from the side away from the operating table 1 to the direction close to the operating table 1. The support walls 311 can preferably be curved surfaces, so that when the motor assembly 100 is placed, it can be better clamped on the outer side of the peripheral wall of the motor assembly 100, thereby achieving the positioning of the motor assembly 100, even if the size of the motor assembly 100 is slightly deviated. A first positioning groove 331 is also formed at the corresponding position of the sliding table 33 and each chute. A protrusion 102 is provided on the peripheral wall of the end of the motor assembly 100. The protrusion 102 can be snapped into the first positioning groove 331, thereby positioning the motor assembly 100 and preventing it from deflecting or rotating when the motor assembly 100 is pushed.

[0047] In this embodiment, the first positioning groove 331 corresponding to the first chute 31 is arranged on a side of the first chute 31 away from the second chute 32 in the width direction, while the first positioning groove 331 corresponding to the second chute 32 is arranged on the bottom of the second chute 32 near the operating table 1. This is determined by the fixed placement angle of the motor assembly 100 during installation. The factors that determine the placement angle will be described in detail below. Of course, the first positioning grooves 331 can also be arranged at the bottom or side of the corresponding chute, or the first positioning groove 331 corresponding to the first chute 31 can be arranged at its bottom, while the first positioning groove 331 corresponding to the second chute 32 can be arranged at its side.

[0048] The first push block 21 slides in engagement with the first chute 31, while the second push block 22 engages with the second chute 32. Each push block may have a positioning block 215 at its bottom. This positioning block 215 engages with a second positioning groove 312 formed in the corresponding chute, achieving both positioning and sliding engagement. The second positioning groove 312 is formed at the bottom of the corresponding chute and may be located on both sides of the chute in its width direction. Each push block also has two positioning blocks 215.

[0049] The operating table 1 is also provided with a support base 34, which is arranged at the end of the sliding table 33 away from the first linear drive mechanism 6. One end of the outer tube 200 is placed on the support base 34 and aligned with the motor assembly 100. The other end of the outer tube 200 abuts the outer tube base 4, which is fixed to the operating table 1. To facilitate the placement of the outer tube 200, the support base 34 can be formed with grooves corresponding to the first and second chute 31 and 32, and the ends of the outer tube 200 can be snapped into these grooves. The ends of the outer tube base 4 corresponding to the outer tube 200 are formed with a first step 41 and a second step 42, both of which are annular. The first step 41 is closer to the lower end of the operating table 1 than the second step 42. The first step 41 is larger than the second step 42. The first step 41 is suitable for tubular motors with large diameters (e.g., 45 mm), while the second step 42 is suitable for tubular motors with small diameters (e.g., 35 mm). The end of the outer tube 200 may abut against one of the corresponding step portions, so that the position of the outer tube 200 is fixed.

[0050] Since the outer tube base 4 is fixed, the position of the outer tube 200 is fixed during assembly, and the adaptation is performed by adjusting the position of the sliding table 33. The sliding table 33 can move back and forth in a straight line along the width direction of the operating table 1. The moving direction is shown in FIG. Figure 4 As shown by the arrow Y, which is perpendicular to the axial direction Y of the tubular motor, the output end 61 of the first linear motion mechanism 6 can selectively cooperate with the first push block 21 or the second push block 22. In the initial state, the output end 61 can be located between the two push blocks. The driving mechanism of the sliding table 33 is not shown, but is a commonly used linear driving mechanism. Figure 12 and Figure 13To facilitate the connection of the first and second push blocks 21, 22 to the output end 61 after they are moved into position, the first linear drive mechanism 6 further includes a coupling 62, which can be independently provided relative to the output end 61 or integrally formed. The coupling 62 is provided at the end of the output end 61 facing each push block. A connecting groove 214 is formed at the end of each push block that mates with the coupling 62. The connecting groove 214 is recessed from the side of each push block proximal to the other push block toward the side distal to the other push block and extends through the end surface facing the output end 61. The connecting groove 214 includes a first groove portion 2141 and a second groove portion 2142 that are interconnected. The second groove portion 2142 is larger than the first groove portion 2141. Along the cross-section of the tubular motor along the axial direction (X), the connecting groove 214 is T-shaped. The first groove portion 2141 is located proximal to the output end 61, while the second groove portion 2142 is located distal to the output end 61. The second groove portion 2142 and the blind hole 213 are spaced apart within each push block. The coupling 62 includes a first connecting portion 621, a second connecting portion 622, and a third connecting portion 623, which are coaxially arranged in sequence. The first connecting portion 621 is connected to the output end 61, the second connecting portion 622 can pass through the connecting groove 214, and the third connecting portion 623 serves as a stop, confined within the second groove 2142, preventing it from disengaging from the corresponding push block by movement along the axial direction X of the tubular motor. Because the second groove 2142 is larger than the first groove 2141, the third connecting portion 623 can abut against the wall of each push block at the transition point between the first groove 2141 and the second groove 2142, allowing each push block to reciprocate axially with the coupling 62.

[0051] A screwdriver 5 is provided on the operating table 1 at a position corresponding to the end of the outer tube 200 facing the motor assembly 100 (the upper end in the placed state), which is preferably an electric screwdriver. The feeding direction of the screwdriver 5 is perpendicular to the axial direction X of the tubular motor, that is, Figure 4 The left direction is indicated by the arrow Y. A first screw hole 103 is formed on the peripheral wall of the end of the motor assembly 100 facing the corresponding push block, and a second screw hole 201 is formed on the peripheral wall of the end of the outer tube 200 facing the motor assembly 100. The angles of the first screw hole 103 and the second screw hole 201 correspond to each other, so that when the motor assembly 100 is pushed into the outer tube 200, the first screw hole 103 and the second screw hole 201 can overlap, and the second screw hole 201 is coaxially arranged with the blade of the screwdriver 5. The different opening angles of the screw holes determine the placement angle of the motor assembly 100 and the outer tube 200 mentioned above. The screwdriver 5 can move back and forth along the straight line indicated by the arrow Y to approach or move away from the outer tube 200, and its driving mechanism also adopts the existing linear driving mechanism.

[0052] The end of the outer tube 200 facing the motor assembly 100 also has a slot 202 formed. This slot 202 is formed by the end surface of the outer tube 200 being recessed away from the motor assembly 100. It is generally U-shaped and engages with the raised portion 102 of the motor assembly 100 to position the motor assembly 100 and the outer tube 200. There may be multiple slots 202, spaced apart along the circumference of the outer tube 200. The raised portion 102 of the motor assembly 100 may also be a matching U-shape, allowing for fine adjustment of the angle during insertion.

[0053] An elastic member 7 is also provided on the support base 34 or the operating table 1. The elastic member 7 and the screwdriver 5 are located on opposite sides of the outer tube 200. The position of the elastic member 7 corresponds to one of the slots 202. The elastic member 7 is rotatably mounted on the support base 34 or the operating table 1, with its rotational axis extending in the same direction as the axial direction X of the tubular motor. The elastic member 7 has a first end 71 and a second end 72 located at opposite ends of the rotational center. The first end 71 forms a snap portion that snaps into the slot 202, and the elastic member 7 maintains the snap portion's tendency to snap into the slot 202. In this embodiment, the elastic member 7 is mounted on the support base 34. The support base 34 is formed with a mounting slot 341 extending through the outer tube 200. The second end 72 of the elastic member 7 abuts the mounting slot 341, ensuring that the first end 71 of the elastic member 7 remains exposed from the mounting slot 341 and is thus inclined to snap into the slot 202. Thereby, the outer tube 200 is automatically locked, ensuring that the second screw hole 202 of the outer tube 200 is aligned with the blade of the screwdriver 5 without the need for additional positioning and operation.

[0054] The assembly device also includes a first stopper 81 and a second stopper 82, which can be set at a position corresponding to the end of the outer tube 200 facing the motor assembly 100. The first stopper 81 and the second stopper 82 can move back and forth in a straight line along the direction indicated by the arrow Y. The first stopper 81 corresponds to the first chute 31, that is, corresponds to the large-diameter tubular motor, and the second stopper 82 corresponds to the second chute 32, that is, corresponds to the small-diameter tubular motor. The first stopper 81 and the second stopper 82 can both be moved to the side of the outer tube 200 away from the operating table 1 to block the outer tube 200 and prevent the outer tube 200 from being repelled by force during the assembly process, causing danger. When the assembly is completed, each stopper leaves the outer tube 200 and resets. There can also be only one stopper, and its stroke can be set appropriately.

[0055] To facilitate automatic driving of the first stopper 81 and the second stopper 82 , the assembly device further includes a second linear drive mechanism 9 , which may be the same as the first linear drive mechanism 6 . The first stopper 81 and the second stopper 82 may be driven independently or synchronously.

[0056] The assembly device of the present invention operates as follows when assembling a tubular motor:

[0057] 1) The assembly device is started, and the type of tubular motor to be assembled is selected (e.g., whether the tube diameter is 45mm or 35mm);

[0058] 2) driving the sliding table 33 to automatically switch so that the push block and the slide groove corresponding to the current pipe diameter move to a position aligned with the first linear drive mechanism 6;

[0059] 3) The operator places the outer tube 200 of the tubular motor to be assembled, and the elastic member 7 automatically snaps into the slot 202 of the outer tube 200. Then the motor assembly 100 is placed in, with the bottom of the motor assembly 100 entering the outer tube 200.

[0060] 4) Start the first linear drive mechanism 6 and the second linear drive mechanism 9. First, the second linear drive mechanism 9 moves the corresponding block to the outside of the outer tube 200. Then the first linear drive mechanism 6 pushes the currently connected push block until the motor assembly 100 is completely pushed into the outer tube 200. The end of the motor assembly 100 is flush with the outer tube 200 and stops automatically. Figure 14 At this time, the first pushing portion 211 of the current pushing block contacts the end surface of the outer tube 200 (the first linear driving mechanism 6 can automatically stop when detecting that the resistance becomes larger). Through this contact, the end surface of the motor assembly 100 is flush with the end surface of the outer tube 200, and no manual adjustment of any components is required to adapt to tubular motors of different lengths (tubular motors with different diameters usually have different lengths).

[0061] Since the upper and lower positions are fixed and the position of the outer tube 200 is fixed, the pushing distance is basically within a small error range. When the distance exceeds the limit, an error can be set to avoid safety accidents.

[0062] Then, the screwdriver 5 can be driven close to the outer tube 200. After it is in place, the screwdriver 5 is started to screw the screws into the first screw hole 103 and the second screw hole 201 to further fix the motor assembly 100 and the outer tube 200.

[0063] 5) The block on the outside of the outer tube 200 is reset, and the operator takes out the assembled tubular motor.
