Description

Technical Field

[0001] This invention relates to the field of automation equipment technology, and specifically to a printer core motor mounting machine. Background Technology

[0002] Generally, during the assembly of a motor and its bracket, after the motor and bracket are pre-positioned along the axial direction, they are fixed together using two or more screws. A motor assembly machine for this purpose includes a positioning device and a robotic arm. The positioning device secures one of the bracket and the motor, while the robotic arm grasps and transports the other of the bracket and the motor. After transport, the bracket is aligned with the motor shaft, and then they are aligned axially to complete the assembly of the bracket and the motor.

[0003] See Figure 1 The motor 92 needs to be installed onto the bracket 91 of the printer core. To reduce the number of steps, only one screw is needed to fix the motor 92 to the bracket 91 after it is installed.

[0004] Specifically, the base plate 910 of the bracket 91 is provided with a central hole 911 and a second hole 912. The bracket 91 is also provided with a structure 914 that is higher than the base plate 910. A bayonet 913 is formed between the structure 914 and the base plate 910. The bayonet 913 opens toward the center line of the central hole 911 and extends circumferentially along the central hole 911. The bayonet 913 and the second hole 912 are located at different circumferential positions of the central hole 911. The motor 92 includes a main body 920, a positioning boss 921 and an output shaft 929 arranged sequentially along its own axial direction. The outer periphery of the main body 920 is provided with a first plate 922 and a second plate 923 at different circumferential positions. The first plate 922 is provided with a first hole 9220.

[0005] When the motor 92 and the bracket 91 are assembled, the positioning boss 921 is installed in the center hole 911 to restrict the movement of the motor 92 in a plane perpendicular to the axial direction. The output shaft 929 passes through the center hole 911 and exits the base plate 910. The first plate 22 and the second plate 923 are both stacked on the base plate 910. The second plate 923 is embedded in the bayonet 913 to restrict the axial movement of the motor 92 on the other side. The first hole 9220 is connected to the second hole 912. After the screw passes through the first hole 9220 and the second hole 912 to lock, it can restrict the rotation of the motor 92 and restrict the axial movement of one side of the motor 92.

[0006] However, in order to form the bayonet 913, the bracket 91 must have a structure 914. This structure 914 will obstruct the second plate 923 from advancing further. If an existing motor mounting machine is used for assembly, when the motor 92 approaches the bracket 91 axially, the obstruction of the structure 914 will prevent the motor 92 from moving forward. Figure 1As shown, the motor is installed directly in the upward straight line, making it difficult for existing motor installation machines to automatically install this type of printer core motor that is fixed with a single screw. Summary of the Invention

[0007] The purpose of this invention is to provide a printer core motor installation machine that automates the installation of a single-screw motor, specifically as described in the background art.

[0008] The printer core motor mounting machine provided by this invention includes a positioning device and an adjustment device. The positioning device includes a fixed base and a rotating base. The rotating base is rotatably connected to the fixed base along a vertical first axis. The fixed base has a bracket placement position, and the rotating base has a motor placement position. A drive insertion hole is provided on the circumferential position of the rotating base, with the opening of the drive insertion hole facing upward. The adjustment device includes a drive mechanism, which includes a rotating component and a drive pin. The rotating component is rotatably arranged along a vertical second axis, and the drive pin is connected to the rotating component and located on the circumferential position of the rotating component. When the adjustment device moves to the working position, the second axis is aligned with the first axis, the drive pin is inserted into the drive insertion hole, and the rotating component can drive the rotating base to rotate synchronously.

[0009] As can be seen from the above scheme, combined with Figure 1 The principle of installing the printer cartridge motor of the present invention is as follows: First, the second plate 923 of the motor 92 and the structure 914 of the bracket 91 are misaligned in the circumferential direction, allowing the motor 92 and the bracket 91 to be inserted into place axially. Then, the motor 92 is rotated to align the first hole 9220 with the second hole 912, and the second plate 923 is inserted into the slot 913. Therefore, the printer cartridge motor installation machine of the present invention places the motor in the motor placement position, and then places the bracket in the bracket placement position. At this time, the motor and the bracket are axially installed in place, but the angle of the motor needs to be adjusted. At this time, the driving pin of the adjusting device is inserted into the driving insertion hole, and the rotating component drives the rotating seat to rotate synchronously. The bracket remains stationary while the motor is driven to rotate, thus completing the angle adjustment of the motor. Finally, the first hole and the second hole are aligned, and the second plate is inserted into the slot. Then, the screws are driven in to complete the motor installation.

[0010] A further embodiment includes an unlocking socket on the fixed base and a first locking socket and a second locking socket on the rotating base. The unlocking socket extends vertically through the base, while the openings of both the first and second locking sockets face downwards. All three sockets are located circumferentially around the first axis, and are arranged sequentially along the circumferential direction of the axis. The positioning device also includes a locking structure and a resetting component. The locking structure includes an unlocking pin and a locking pin, both vertically aligned, and is movably mounted vertically on the fixed base. The resetting component connects the locking structure to the fixed base. Between the fixed seats, the spring force of the reset member tends to bring the locking structure to a higher locking position; when the locking structure is in the locked position and the rotating seat is in the first position, the unlocking pin is inserted into the unlocking socket and the locking pin is inserted into the first locking socket; when the locking structure is in the locked position and the rotating seat is in the second position, the unlocking pin is inserted into the unlocking socket and the locking pin is inserted into the second locking socket; the adjusting device includes a pressure rod, when the adjusting device moves to the working position, the pressure rod is inserted into the unlocking socket and forces the unlocking pin to leave the unlocking socket, while simultaneously driving the locking pin to leave the first locking socket or the second locking socket.

[0011] As can be seen from the above, if the rotating seat is allowed to rotate freely without restriction, a slight deflection of the rotating seat may cause the driving hole to deviate from the predetermined position for insertion with the driving pin. This would not only prevent subsequent actions from being performed, but the driving pin and the rotating seat may also be damaged due to collisions. To ensure the smooth insertion of the pin hole and to protect the components, this invention also includes a locking mechanism. The locking pin can lock the rotating seat in the first or second position, ensuring accurate and smooth insertion of the driving pin hole. Furthermore, since the unlocking pin and the locking pin rise and fall synchronously, when the pressure rod of the adjusting device presses down on the unlocking pin, the locking pin disengages from the rotating seat, unlocking the rotating seat and restoring its rotational freedom, allowing it to be driven to rotate by the driving pin.

[0012] A further proposed solution is that the adjustment device includes a lifting drive unit, a first lifting seat, a second lifting seat, and an elastic element; the lifting drive unit drives the first lifting seat to rise and fall, the second lifting seat is movably connected to the first lifting seat, the elastic element is disposed between the first and second lifting seats, and the elastic force of the elastic element tends to keep the second lifting seat in the lower limit position; the pressure rod is connected to the first lifting seat, the driving mechanism is connected to the second lifting seat, and when the second lifting seat is in the lower limit position, the position of the driving pin is lower than the position of the pressure rod.

[0013] As can be seen from the above, to ensure accurate insertion of the drive pin, a better sequence of actions would be to insert the drive pin first and then unlock the rotating seat. However, setting up two drive units for these two sequential actions would increase machine costs. This invention cleverly utilizes the fact that both the insertion and unlocking actions are downward movements. By employing a double lifting seat, the height difference between the pressure rod and the drive pin, and the reset function of the elastic element, only one lifting drive unit is needed to achieve the sequential movement of the drive pin and pressure rod. Driven by the lifting drive unit, the lower drive pin inserts into the drive hole first until the drive pin hole reaches the bottom and can no longer descend. At this point, the pressure rod can continue to descend until unlocking is complete. After the adjusting device rises, under the elastic force of the elastic element's deformation recovery, the drive pin naturally returns to its lower limit position below the pressure rod.

[0014] Another further embodiment is that the rotating component includes a downwardly protruding clamping part, and the adjusting device also includes a downwardly positioned clamping part. The clamping part is located at the second axis, and the clamping part is positioned circumferentially at the second axis. When the adjusting device is in the working position, the clamping part is positioned opposite the motor placement position from above, and the clamping part is positioned opposite the motor placement position from above.

[0015] As can be seen above, the clamping part is used to clamp the motor output shaft below it to prevent the motor from loosening; the clamping component is used to clamp the bracket below it. Since the bracket cooperates with the motor, the rotation of the motor may drive the bracket, so the clamping component can stabilize the bracket and prevent it from loosening. Therefore, this setting ensures that the process of rotating and adjusting the motor angle is carried out stably and effectively.

[0016] A further improvement is that the clamping element is made of cushioning material; the fixing base is also equipped with a pad, which is located below the bracket placement position and is made of cushioning material.

[0017] As can be seen from the above, the clamping parts and pads stabilize the bracket from both the top and bottom. Whether it is during the motor angle adjustment stage or the screw-driving stage, the bracket can be kept stable. Moreover, the clamping parts and pads made of buffer material can better protect the bracket.

[0018] Another further design is that the motor placement position includes a motor body placement area, the center of which coincides with the rotation axis of the rotating seat; the motor placement position also includes a motor side restriction area, which is located on the outer periphery of the motor body placement area and is radially connected to the motor body placement area, and the rotating seat blocks the motor side restriction area from the front and rear sides of its own rotation direction.

[0019] As can be seen above, after the first plate of the motor is placed in the restricted area on the side of the motor, it is restricted from rotating by the rotating seat, thereby ensuring that the motor and the rotating seat rotate synchronously and that the motor angle can be accurately adjusted after the rotating seat rotates.

[0020] A further improvement is that the rotating base is also provided with a motor side clearance opening, which is located on the outer periphery of the motor body placement area and is connected to the motor body placement area radially. The motor side clearance opening is connected to the bracket placement position along the rotation direction.

[0021] As can be seen from the above, the motor angle adjustment action also needs to simultaneously complete the insertion of the second plate of the motor into the bracket slot. Therefore, the motor side clearance slot should be located on the outer periphery of the motor body placement area, which can also communicate with the bracket placement position. After the motor is accurately placed, the second plate will be located in the motor side clearance slot. The setting of the motor side clearance slot avoids the rotating seat from blocking or hindering the second plate from entering the bracket slot, ensuring that the second plate is smoothly inserted into the slot.

[0022] A further embodiment is that the fixed base includes a platform and a support structure for supporting the platform. The fixed base also includes a setting space formed below the platform, and the platform has a mounting recess recessed on its upper side. The rotating seat is set in the mounting recess, and the mounting recess restricts the rotation range of the rotating seat between a first position and a second position. A locking structure and a reset component are set in the setting space.

[0023] As can be seen from the above, the design of the mounting recess not only limits the rotation range of the rotating seat, but also makes the upper part of the platform flatter, which is more conducive to the placement and positioning of the bracket; while the locking mechanism is set in the space below the platform, avoiding the motor placement position and the bracket placement position. The distribution of each area is reasonable, making better use of the three-dimensional space, and the positioning device structure is more compact.

[0024] A further proposed solution is that the platform has a notch, and the platform blocks the notch from opposite sides in the horizontal direction; the support structure includes two supports arranged opposite each other in the horizontal direction, and the fixing seat forms a vertical extension between the two supports and below the notch; the bracket mounting position includes the notch and the vertical extension.

[0025] As can be seen from the above, under this configuration, by setting up the platform and support structure, a bracket placement position is formed that allows the long bracket to be positioned in a vertical posture, thus meeting the motor installation and positioning requirements.

[0026] Another further solution is that the platform is provided with a first through hole and a second through hole along the vertical direction; the positioning device also includes a first guide tube and a second guide tube, both of which are vertically arranged in the setting space and connected to the lower side of the platform. The first guide tube is vertically connected to the first through hole, and the second guide tube is vertically connected to the second through hole; the unlocking pin passes through the first guide tube and the first through hole, and the locking pin passes through the second guide tube and the second through hole.

[0027] As can be seen from the above, this setup further makes effective use of the space by installing a first conduit and a second conduit to improve the straightness and smoothness of the vertical movement of the unlocking pin and the locking pin, ensuring that the action remains effective.

[0038] See Figure 2 The printer core motor mounting machine of this embodiment includes a positioning device 1 and an adjustment device 2. The bracket 91 and motor 92 to be assembled are both transferred and placed on the positioning device 2 by a robot (not shown), and then the angle of the motor 92 is adjusted by the adjustment device 2.

[0039] See Figures 3 to 6The positioning device 1 includes a fixed base 3, a rotating base 4, and a locking mechanism. The locking mechanism includes a locking structure 5, a first conduit 38, a second conduit 39, a reset component 61, and a traction component 69.

[0040] The fixed base 3 includes a platform 31, a support structure, and a base 33 arranged sequentially from top to bottom. The support structure includes two support bodies 32 arranged opposite each other along the second horizontal direction (shown in the y-axis direction in the figure), and the platform 31 is supported by the two support bodies 32. The platform 31 has a mounting recess 310 recessed on its upper side. The rotating seat 4 is rotatably connected to the fixed base 3 along the first vertical axis 40 and is disposed in the mounting recess 310, and the mounting recess 310 also restricts the rotation range of the rotating seat 4 between the first position and the second position.

[0041] The fixed base 3 also forms a setting space 500, which is located below the platform 31, between the two supports 32, and above the base 33. The locking structure 5, the reset member 61, the first conduit 38, and the second conduit 39 are all located in the setting space 500.

[0042] Combined Figure 3 , Figure 7 and Figure 8 The mounting base 3 has a bracket placement position 300. The bracket placement position 300 is the location where the bracket 91 is placed on the mounting base 3. Further, the platform 31 has a notch 319, which is blocked by the platform 31 from opposite sides in the second horizontal direction. The mounting recess 310, the notch 319, and the outside of the platform 31 are connected sequentially along the first horizontal direction (x-axis direction in the figure). The mounting base 3 forms a vertical extension 329 between the two supports 32 and below the notch 319. The bracket placement position 300 includes a portion of space above the mounting recess 310, the notch 319, and the vertical extension 329.

[0043] The rotating base 4 is provided with a motor placement position 400. The motor placement position 400 is the location where the motor 92 is placed on the rotating base 4. Further, the motor placement position 400 includes a motor body placement area 401, which is used to accommodate the motor body 920 (…). Figure 1 (As shown). The center of the motor body placement area 401 coincides with the first axis 40.

[0044] The motor placement position 400 also includes a motor side restriction area 402, which is located on the outer periphery of the motor body placement area 401 and communicates with the motor body placement area 401 radially. The rotating seat 4 blocks the motor side restriction area 402 from the front and rear sides in its own rotation direction. The motor side restriction area 402 is used to accommodate the first plate 922 of the motor 92 and restrict the rotation of the first plate 922.

[0045] The rotating base 4 is also provided with a motor side clearance opening 403. The motor side clearance opening 403 is located on the outer periphery of the motor body placement area 401 and communicates with the motor body placement area 401 radially. The motor side clearance opening 403 communicates with the notch 319 of the bracket placement position 300 in the rotation direction. The motor side clearance opening 403 is used to accommodate the second plate 923 of the motor 92. More importantly, the opening and communication design of the motor side clearance opening 403 prevents the rotating base 4 from blocking or hindering the second plate 923 from entering the bayonet 913 of the bracket 91, ensuring that the second plate 923 can be smoothly inserted into the bayonet 913.

[0046] See also Figures 3 to 6 The rotating base 4 is provided with a drive socket 41, a first locking socket 42, and a second locking socket 43 on its circumferential position. In this embodiment, the first locking socket 42, the drive socket 41, and the second locking socket 43 are arranged sequentially along the circumference of the first axis 40.

[0047] Furthermore, the opening of the drive socket 41 faces upward, while the openings of the first locking socket 42 and the second locking socket 43 face downward. In this embodiment, in order to conform to the above-mentioned opening rules and facilitate processing, the drive socket 41, the first locking socket 42, and the second locking socket 43 all penetrate the rotating seat 4 vertically.

[0048] Platform 31 is provided with an unlocking socket 311, a first through hole 312, and a second through hole 313 arranged vertically. All three are located circumferentially around the first axis 40. The unlocking socket 311 extends vertically and communicates vertically with the first through hole 312, situated above the first through hole 312. The unlocking socket 311 has a bottom wall 3119 with a connecting hole of a smaller inner diameter, through which it connects to the first through hole 312 below it. The second through hole 313 is closer to the first axis 40 than the first through hole 312.

[0049] The first conduit 38 and the second conduit 39 are both vertically arranged in the setting space 500 and connected to the lower side of the platform 31. The first conduit 38 is vertically connected to the first through hole 312, and the second conduit 39 is vertically connected to the second through hole 313. The traction component 69 is fixedly connected to the lower side of the platform 31, and the traction component 69 is located between the first conduit 38 and the second conduit 39.

[0050] The locking structure 5 includes a base 50 and an unlocking pin 51 and a locking pin 52 connected to the base 50. Both the unlocking pin 51 and the locking pin 52 extend vertically upward from the base 50. The unlocking pin 51 passes through the first conduit 38, the first through hole 312, the connecting hole and the unlocking insertion hole 311 from bottom to top. The locking pin 52 passes through the second conduit 39 and the second through hole 313 from bottom to top. In this way, the locking structure 5 is movably mounted on the fixed base 3 vertically.

[0051] The reset member 61 is a tension spring. The reset member 61 is connected between the locking structure 5 and the fixed base 3. More specifically, the reset member 61 is pulled vertically between the traction member 69 and the base 50. Under the action of the rebound force of the reset member 61, the locking structure 5 tends to be in a higher locking position.

[0052] When the locking structure 5 is in the locked position and the rotating seat 4 is in the first position, the unlocking pin 51 is inserted into the unlocking socket 311, and the locking pin 52 is inserted into the first locking socket 42; when the locking structure 5 is in the locked position and the rotating seat 4 is in the second position, the unlocking pin 51 is inserted into the unlocking socket 311, and the locking pin 52 is inserted into the second locking socket 43. Figures 3 to 6 As shown, the locking structure 5 is in the locked position and the rotating seat 4 is in the first position. It can be seen that, when not unlocked, the rotating seat 4 can be locked in its current position regardless of whether it is in the first or second position, under the action of the locking mechanism.

[0053] See Figure 8 When the rotating seat 4 is in the first position, the motor 92 and the bracket 91 can be placed in place, and there is no structural obstruction due to the angle being offset. The motor 92 and the bracket 91 are axially fitted in place, but the first plate 922 of the motor 92 is offset from the base plate 910 of the bracket 91, and the second hole 912 is offset from the first hole 9220.

[0054] See Figure 9 and Figure 10The adjusting device 2 includes a lifting drive unit 28, a third lifting seat 27, a first lifting seat 261, a second lifting seat 262, a first elastic element 62, a second elastic element 63, a pressure rod 25, a drive pin 24, a rotating element 23, a rotation drive unit 239, and a clamping element 22. The lifting drive unit 28 is a cylinder, and the end of the cylinder drives the third lifting seat 27 to move up and down. The first lifting seat 261 is slidably connected to the third lifting seat 27, and the first elastic element 62 is connected between the first lifting seat 261 and the third lifting seat 27. Under the action of the rebound force of the first elastic element 62, the first lifting seat 261 tends to be held at its lower limit position. The second lifting seat 262 is slidably connected to the first lifting seat 261, and the second elastic element 63 is disposed between the first lifting seat 261 and the second lifting seat 262. The elastic force of the second elastic element 63 tends to keep the second lifting seat 262 at its lower limit position. Wherein, the first elastic element 62 and the second elastic element 63 are both compression springs, and the second elastic element 63 is the elastic element of the present invention.

[0055] The pressure rod 25 is connected to the first lifting seat 261 and extends downward. The driving mechanism, including the driving pin 24, the rotating component 23, and the rotary drive unit 239, is connected to the second lifting seat 262. The rotary drive unit 239 is a vertically positioned motor that drives the rotating component 23 to rotate along the second axis 20. The driving pin 24 is connected to the rotating component 23 and located on its circumferential side. The driving pin 24 extends downward, and when both the first lifting seat 261 and the second lifting seat 262 are at their respective lower limit positions, the lower end of the driving pin 24 is lower than the lower end of the pressure rod 25.

[0056] Combination Figure 1 , Figure 5 , Figure 6 and Figure 8 When the adjusting device 2 moves to the working position, the pressure rod 25 inserts into the unlocking socket 311 and forces the unlocking pin 51 out of the unlocking socket 311, while simultaneously driving the locking pin 52 out of the first locking socket 42 or the second locking socket 43. It can be seen that after placing the motor 92 in the motor placement position 400 and the bracket 91 in the bracket placement position 300, the motor 92 and the bracket 91 are axially installed in place. Next, the rotating component 23 can drive the motor 91 to rotate to adjust the angle of the motor 91. During the process, the driving pin 24 inserts into the driving socket 41, and after the rotating component 23 drives the rotating seat 4 to rotate synchronously, the bracket 91 remains stationary while the motor 92 is driven to rotate, thus completing the angle adjustment of the motor 92. Finally, the first hole 9220 is aligned with the second hole 912, and the second plate 923 is inserted into the bayonet 913. Then, the screws are driven in to complete the installation of the motor 92.

[0057] Furthermore, this invention considers the locking of the rotating seat 4. To ensure the smooth completion of the pin insertion and to protect the components, this invention also provides a locking mechanism. The locking pin 52 can lock the rotating seat 4 in the first or second position, ensuring that the drive pin 24 can be inserted accurately and smoothly. Since the unlocking pin 51 and the locking pin 52 rise and fall synchronously, the pressure rod 25 of the adjusting device 2 presses down the unlocking pin 51, and the locking pin 52 then exits the rotating seat 4, unlocking the rotating seat 4. This allows the rotating seat 4 to regain its rotational freedom and be driven to rotate by the drive pin 24.

[0058] See also: Figure 3 and Figure 10 The clamping part 231 is located at the second axis 20, and the clamping member 22 is positioned circumferentially on the second axis 20. A pad 331 is also provided on the fixed base 3, positioned on the base 33 and below the bracket placement position 300. The clamping part 231, clamping member 22, and pad 331 are all made of cushioning material. The clamping part 231 clamps the output shaft of the motor below it to prevent the motor from loosening. The clamping member 22 clamps the bracket below it. Since the bracket cooperates with the motor, the motor rotation may drive the bracket; therefore, the clamping member 22 can stabilize the bracket and prevent it from loosening. Thus, this arrangement ensures that the process of rotating and adjusting the motor angle is carried out stably and effectively. The clamping member 22 and the pad stabilize the bracket from both the top and bottom, ensuring bracket stability during both motor angle adjustment and screw tightening stages. Furthermore, the use of cushioning material in these clamping and pad structures better protects the motor and bracket.

[0059] Finally, it should be emphasized that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
