Description

Technical Field

[0001] This invention relates to the field of product assembly equipment technology, and in particular to an assembly machine. Background Technology

[0002] Currently, there is an electronic cigarette product that requires a rubber cap. The rubber cap is mainly composed of a semi-circular arched plate-shaped workpiece and foam and rubber rings pasted inside the arch of the workpiece. This product is usually packaged by pasting foam and rubber rings inside the arch of the workpiece and then inverting it into a blister tray.

[0003] Previously, when attaching rubber rings and foam to the workpiece, loading, attaching, and unloading all relied on manual operation by workers on the assembly line. Especially during unloading, the workpiece with attached foam and rubber rings needed to be turned upside down before being output. Manual operation was cumbersome, prone to errors, and inefficient. Summary of the Invention

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes an assembly machine that can improve the assembly efficiency and quality of rubber caps.

[0005] An assembly machine according to an embodiment of the present invention includes a turntable, on which a plurality of fixtures are evenly distributed along the circumference of the turntable. The turntable rotates such that the fixtures sequentially correspond to a feeding device, a rubber ring transfer device, a foam transfer device, and a discharging device on the outer periphery of the turntable. The feeding device is used to transfer workpieces into the corresponding fixtures; the rubber ring transfer device is used to transfer rubber rings onto the workpieces in the corresponding fixtures and attach the rubber rings to the workpieces; the foam transfer device is used to transfer foam onto the workpieces to which the rubber rings have been attached; the discharging device includes a first transfer mechanism, a reversing mechanism, and a discharge mechanism. The system includes a material handling mechanism, a transfer platform, and an output mechanism. The first transfer mechanism is equipped with a vision detector. The first transfer mechanism is used to pick up workpieces with rubber rings and foam attached. When the vision detector detects that the rubber rings and foam are attached to the workpiece in a qualified position, the first transfer mechanism places the workpiece into a reversing mechanism. When the vision detector detects that the rubber rings and foam are not attached to the workpiece in a qualified position, the first transfer mechanism places the workpiece into a discharge mechanism. The reversing mechanism is used to flip the workpiece 180° and place the workpiece in an inverted position on the transfer platform. The output mechanism is used to remove the workpiece from the transfer platform.

[0006] It has at least the following beneficial effects: The turntable, in conjunction with the feeding device, rubber ring transfer device, foam transfer device, and unloading device, realizes the entire process from workpiece feeding to rubber ring and foam bonding, eliminating the tedious manual bonding of rubber rings and foam and improving efficiency. In addition, the first transfer mechanism uses a vision detector to detect the assembly quality in real time, rejecting unqualified workpieces through the unloading mechanism, while qualified workpieces can be rotated 180° with the reversing mechanism. The central transfer platform supports the inverted workpieces to prevent them from being flipped back by human touch, avoiding the directional errors and missed inspections that are prone to occur during manual unloading. The turntable forms a production line from feeding to bonding to unloading, significantly improving production efficiency and product qualification rate, filling the technological gap in assembly machines in this field.

[0007] According to some embodiments of the present invention, the reversing mechanism includes a linear drive module, a lifting cylinder, a rotary cylinder, and a support block. The lifting cylinder is disposed on the linear drive module and is used to drive the lifting cylinder to move between the turntable and the rotary table. The rotary cylinder is connected to the main shaft of the lifting cylinder and is used to drive the rotary cylinder to lift and lower. The support block is connected to the main shaft of the rotary cylinder and is used to drive the support block to rotate. The support block is used to place the workpiece transferred from the first transfer mechanism. When a workpiece is placed on the support block, the rotary cylinder drives the support block to rotate and flip the workpiece 180°. The linear drive module drives the support block to move above the turntable, and the lifting cylinder drives the support block to descend, so that the flipped workpiece on the support block is placed on the turntable.

[0008] According to some embodiments of the present invention, the support block includes at least a pair of mounting slots disposed opposite each other in the vertical direction, the mounting slots being used to load workpieces transferred from the first transfer mechanism.

[0009] According to some embodiments of the present invention, the output mechanism includes a frame, a lifting frame, a receiving unit, an output unit, and a transfer module. The lifting frame is slidably connected to the frame vertically. Several sets of receiving units are vertically and equidistantly arranged within the lifting frame. Both the receiving units and the transfer module are disposed on the frame. The lifting frame is used to drive the receiving units to correspond with the output units. The output unit is used to place a tray, which is used to place a blister pack. The transfer module is used to transfer the workpiece on the transfer table to the blister pack on the tray of the output unit. The output unit is configured to transport the tray to the corresponding receiving unit.

[0010] According to some embodiments of the present invention, the output mechanism includes a connecting transmission component and a power component, both of which are mounted on the frame. The connecting transmission component is connected to the output unit and configured to connect to or disconnect from the receiving unit. When the connecting transmission component is connected to the receiving unit, the power component drives the output unit to operate, the output unit drives the connecting transmission component to operate, and the connecting transmission component drives the receiving unit to operate. The output unit transports the pallet to the corresponding receiving unit, and the receiving unit receives the pallet transported by the output unit. When the receiving unit is loaded with a pallet, the connecting transmission component disconnects from the receiving unit, and the lifting frame moves to align the unloaded receiving unit with the output unit so as to receive the pallet delivered by the output unit.

[0011] According to some embodiments of the present invention, the connecting transmission component includes a connecting gear, a rotating arm, and a thrust cylinder. A first gear is provided on the output unit, which can drive the first gear to rotate. A second gear is provided on the receiving unit, which can drive the receiving unit to operate. The rotating arm is rotatably connected to the output unit, and the connecting gear is rotatably connected to the rotating arm. The connecting gear meshes with the first gear. One end of the thrust cylinder is hinged to the frame, and the other end of the thrust cylinder is hinged to the rotating arm. The thrust cylinder is used to drive the rotating arm to rotate so as to drive the connecting gear to revolve around the first gear, thereby causing the connecting gear to mesh with or disengage from the second gear on the corresponding receiving unit.

[0012] According to some embodiments of the present invention, both the receiving unit and the output unit are synchronous belts. Each receiving unit and the output unit has a drive shaft at one end opposite to the other. The synchronous belt is wound around the corresponding drive shaft, which drives the corresponding synchronous belt to rotate. The drive shaft of the output unit is connected to a power component, which drives the drive shaft of the output unit to rotate to drive the corresponding synchronous belt to rotate. A first gear is disposed on the drive shaft of the output unit, and a rotating arm is rotatably connected to the drive shaft of the output unit. A second gear is disposed on the drive shaft of the receiving unit. When the connecting gear meshes with the second gear, the drive shaft of the output unit drives the drive shaft of the receiving unit to rotate through the connecting gear and the second gear, thereby causing the drive shaft of the receiving unit to drive the corresponding synchronous belt to rotate. The synchronous belt is used to support the pallet.

[0013] According to some embodiments of the present invention, a pressing device is also included, which is disposed between the foam transfer device and the feeding device. The pressing device includes a bracket and a pressing cylinder. The pressing cylinder is disposed on the bracket. The free end of the output shaft of the pressing cylinder is provided with a first conforming pressing block and a second conforming pressing block. When the turntable rotates to make the tooling correspond to the pressing device, the first conforming pressing block is used to press the rubber ring in the workpiece, and the second conforming pressing block is used to press the foam in the workpiece.

[0014] According to some embodiments of the present invention, a laser detector is also included, which is disposed between the clamping device and the unloading device. When the turntable rotates to align the tooling with the laser detector, the laser detector is used to detect the bonding position of the foam and rubber ring in the workpiece.

[0015] According to some embodiments of the present invention, the discharge mechanism is a conveyor belt, which is disposed between the reversing mechanism and the turntable.

[0016] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Detailed Implementation

[0019] In the description of this invention, it should be understood that the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0020] In the description of this invention, the use of "first" and "second" is for the purpose of distinguishing technical features only, and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated or the order of the technical features indicated.

[0021] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0022] Reference Figures 1 to 12 This invention discloses an assembly machine, including a turntable 100. The turntable 100 is provided with a plurality of tooling fixtures 110 evenly distributed along the circumference of the turntable 100. The rotation of the turntable 100 causes the tooling fixtures 110 to correspond sequentially to a feeding device 200, a rubber ring transfer device 300, a foam transfer device 400, and a discharging device 500 on the outer periphery of the turntable 100. The feeding device 200 is used to transfer a workpiece 800 into the corresponding tooling fixture 110. The rubber ring transfer device 300 is used to transfer a rubber ring 810 onto the workpiece 800 in the corresponding tooling fixture 110 and attach the rubber ring 810 to the workpiece 800. The foam transfer device 400 is used to transfer foam 820 onto the workpiece 800 to which the rubber ring 810 is attached. It is understandable that the rotation of turntable 100 refers to its circular motion around its own axis. The rotation of turntable 100 is mainly driven by a motor or other components that can output torque. Besides a motor, these components can also be pneumatic motors, hydraulic motors, or internal combustion engines. These components are primarily connected to the turntable via transmission components such as belts, chains, or gears, thus driving the turntable to rotate. It is also understandable that rubber ring 810 and foam 820 refer to rubber rings and foam blocks suitable for installation within the arch of workpiece 800.

[0023] Reference Figure 12 The tooling 110 includes a base 111 and a cover 112. The upper end of the base is provided with a guide post 113, and the cover 112 is provided with a corresponding guide hole 114. The guide post 113 is used to insert into the guide hole 114 on the cover 112. The upper end of the base 111 is provided with a receiving groove 115 for accommodating the workpiece 800. The cover 112 is also provided with a clearance opening 116. The cover 112 is used to block the edge of the workpiece 800, and the clearance opening 116 is used to expose the arch of the workpiece 800, thereby facilitating the operation of attaching the rubber ring 810 and foam 820. When unloading, the cover removal component 120 picks up and transfers the cover 112, so that the first transfer mechanism 510 can successfully remove the workpiece 800 with the rubber ring 810 and foam 820 attached.

[0024] Reference Figure 1The cap removal assembly 120 specifically includes a first cylinder 121, a second cylinder 122, and a fourth suction nozzle 123. A mounting plate 130 is located at the center of the turntable 100. The mounting plate 130 does not rotate. The first cylinder 121 is mounted on the mounting plate 130 and corresponds to the first transfer mechanism 510. The first cylinder 121 is mounted on the turntable 100. The second cylinder 122 is connected to the main shaft of the first cylinder 121. The first cylinder 121 is used to drive the second cylinder 122 to move radially along the turntable 100. The fourth suction nozzle 123 is mounted on the main shaft of the second cylinder 122. The second cylinder 122 is used to drive the fourth suction nozzle 123 to move up and down. The fourth suction nozzle 123 is used to pick up the cap 112.

[0025] Reference Figure 13 The rubber ring transfer device 300 includes a loading platform 310 supporting the rubber ring 810 and a second transfer mechanism 320 for transferring the rubber ring 810. The execution end of the second transfer mechanism 320 is provided with a second suction nozzle 321. The second transfer mechanism 320 is used to drive the second suction nozzle 321 to pick up the rubber ring 810 on the loading platform 310 and transfer it into the arch of the workpiece 800.

[0026] Reference Figure 14 The foam transfer device 400 includes a foam conveyor belt 410 and a third transfer mechanism 420. The foam conveyor belt 410 is used to transport foam. The execution end of the third transfer mechanism 420 is provided with a third suction nozzle 421. The third transfer mechanism 420 is used to drive the third suction nozzle 421 to pick up the foam 820 on the foam conveyor belt 410 and transfer it into the arch of the workpiece 800.

[0027] Reference Figures 1 to 6The unloading device 500 includes a first transfer mechanism 510, a reversing mechanism 520, a discharge mechanism 530, a transfer table 540, and an output mechanism 550. The first transfer mechanism 510 is equipped with a vision detector 513. The first transfer mechanism 510 is used to pick up the workpiece 800 with rubber rings 810 and foam 820 pasted on it. When the vision detector 513 detects that the rubber rings 810 and foam 820 are pasted on the workpiece 800 in a qualified position, the first transfer mechanism 510 puts the workpiece 800 into the reversing mechanism 520. When the vision detector 513 detects that the rubber rings 810 and foam 820 are pasted on the workpiece 800 in a qualified position, the first transfer mechanism 510 puts the workpiece 800 into the discharge mechanism 530. The reversing mechanism 520 is used to flip the workpiece 800 180° and place the workpiece 800 in an inverted position on the transfer table 540. The output mechanism 550 is used to remove the workpiece 800 from the transfer table 540. It should be noted that the so-called qualified position of the rubber ring 810 and foam 820 on the workpiece 800 means that the rubber ring 810 and foam 820 are attached to the designated position of the workpiece 800 without deviating from the designated position. Otherwise, the attachment position is unqualified. The workpiece 800 with unqualified attachment of the rubber ring 810 and foam 820 is output from the discharge mechanism 530.

[0028] It should be noted that both the second transfer mechanism 320 and the third transfer mechanism 420 are three-axis motion modules. These three-axis motion modules are common in automation design, primarily used to change the position of their actuators in space through three-axis movement. A robotic arm can also be used instead of a three-axis motion module. "Pick-up" refers to the operation of removing the workpiece 800, including but not limited to suction, adhesion, or clamping. The first transfer mechanism 510 includes a two-axis motion module 511 and a first suction nozzle 512. The first suction nozzle 512 is connected to the actuator of the two-axis motion module 511. The two-axis motion module 511 drives the first suction nozzle 512 to pick up the workpiece 800 with the rubber ring 810 and foam 820 adhered to it. The two-axis motion module 511 is a conventional device.

[0029] It should be noted that the first suction nozzle 512, the second suction nozzle 321, the third suction nozzle 421 and the fourth suction nozzle 123 are all components used to perform suction or release actions. This action cannot be completed by a single suction nozzle. The suction nozzle needs to be connected to conventional pneumatic components in the fields of negative pressure generator to achieve the suction or release action. That is, how the suction nozzle generates suction is a conventional technical means in this field.

[0030] It should be understood that the turntable 100, in conjunction with the feeding device 200, rubber ring transfer device 300, foam transfer device 400, and unloading device 500, realizes the entire process of workpiece 800 from feeding to attaching rubber rings and foam, eliminating the tedious manual attachment of rubber rings and foam and improving efficiency. In addition, the first transfer mechanism 510 uses a vision detector 513 to detect the assembly quality in real time, and rejects unqualified workpieces 800 through the unloading mechanism 530. Qualified workpieces 800 can be rotated 180° with the reversing mechanism 520. The intermediate transfer table 540 carries the upside-down workpieces 800 to prevent them from being flipped back by human touch, avoiding directional errors and missed inspections that are prone to occur during manual unloading. The turntable 100 forms a production line from feeding to attaching to unloading, significantly improving production efficiency and product qualification rate, filling the technological gap in assembly machines in this field.

[0031] Reference Figure 3 and Figure 4 The reversing mechanism 520 includes a linear drive module 521, a lifting cylinder 522, a rotary cylinder 523, and a support block 524. The lifting cylinder 522 is mounted on the linear drive module 521 and is used to drive the lifting cylinder 522 to move between the central turntable 540 and the turntable 100. The rotary cylinder 523 is connected to the main shaft of the lifting cylinder 522 and is used to drive the rotary cylinder 523 to move up and down. The support block 524 is connected to the main shaft of the rotary cylinder 523. Rotary cylinder 523 drives the support block 524 to rotate. The support block 524 is used to place the workpiece 800 transferred from the first transfer mechanism 510. When the workpiece 800 is placed on the support block 524, the rotary cylinder 523 drives the support block 524 to rotate, flipping the workpiece 800 by 180°. The linear drive module 521 moves the support block 524 above the transfer platform 540. The lifting cylinder 522 drives the support block 524 to descend, so that the flipped workpiece 800 on the support block 524 is placed on the transfer platform 540. It can be understood that the linear drive module 521 can be an electric cylinder, a pneumatic cylinder, a hydraulic cylinder, or a motor-driven linkage mechanism, etc.

[0032] Reference Figure 4The support block 524 includes at least one pair of mounting grooves 524a arranged opposite each other in the vertical direction. The mounting grooves 524a are used to load the workpiece 800 transferred from the first transfer mechanism 510. It should be noted that the opening of the mounting groove 524a extends radially along the rotation axis of the rotary cylinder 523. The mounting groove 524a is provided with a plurality of suction holes. The mounting groove 524a is used to load the workpiece 800, and the suction holes are used to suction the workpiece 800. It is understood that the suction holes are not independent, but are connected to a conventional negative pressure emitter in the field. How the suction holes generate suction is a conventional technical means in the field. It should be noted that an air gap top block 830 is provided at the arched back of the workpiece 800. After the workpiece 800 is installed in the mounting groove 524a, because the arched back of the workpiece 800 is installed in close contact with the mounting groove 524a, the air gap top block 830 is needed to balance the pressure at the contact surface to prevent the workpiece 800 from becoming difficult to release. Understandably, if the workpiece 800 is a sheet metal part made of iron, an electromagnet can also be installed in the mounting slot 524a to attract and release the workpiece 800 by switching the power on and off.

[0033] Reference Figure 1 , Figure 2 , Figure 5 and Figure 6 The output mechanism 550 includes a frame 551, a lifting frame 552, a receiving unit 553, an output unit 554, and a transfer module 555. The lifting frame 552 is vertically slidably connected to the frame 551. Several sets of receiving units 553 are vertically and equidistantly arranged within the lifting frame 552. Both the receiving units 553 and the transfer module 555 are located on the frame 551. The lifting frame 552 is used to drive the receiving units 553 to correspond with the output units 554. The output unit 554 is used to place a tray 900, and the tray 900 is used to place a blister tray 910. The transfer module 555 is used to transfer the workpiece 800 on the transfer table 540 to the blister tray 910 of the tray 900 on the output unit 554. The output unit 554 is configured to transport the tray 900 to the corresponding receiving unit 553. It should be noted that the receiving unit 553 is a synchronous belt, which is distributed on both sides of the lifting frame 552 along the direction perpendicular to the output direction. The tray 900 serves as a transfer medium to transport the blister tray, while the blister tray 910 is the component that loads the workpiece 800 when unloading. Each layer of receiving unit 553 is equipped with a tray 900.

[0034] Reference Figure 5The output mechanism 550 includes a connecting transmission component 556 and a power component 557, both of which are mounted on the frame 551. The connecting transmission component 556 is connected to the output unit 554. The connecting transmission component 556 is configured to either connect to or disconnect from the receiving unit 553. When the connecting transmission component 556 is connected to the receiving unit 553, the power component 557 drives the output unit 554 to operate, and the output unit 554 drives the connecting transmission component 556. When the device is in operation, the connecting transmission component 556 drives the receiving unit 553 to operate, and the output unit 554 transports the pallet 900 to the corresponding receiving unit 553. The receiving unit 553 receives the pallet 900 transported by the output unit 554. When the receiving unit 553 is loaded with the pallet 900, the connecting transmission component 556 disengages from the receiving unit 553, and the lifting frame 552 moves to position so that the unloaded receiving unit 553 corresponds to the output unit 554, so as to receive the pallet 900 delivered by the output unit 554. It should be noted that during material unloading, the lifting frame 552 is in the raised state. At this time, the lowermost receiving unit 553 in the lifting frame 552 corresponds to the output unit 554. Driven by the power component 557 and the transmission component 556, the tray 900 on the receiving unit 553 is transported to the output unit 554. After the tray 900 on the output unit 554 is loaded with the workpiece 800, the power component 557 reverses and transports the tray 900 back to the lowermost receiving unit 553 in the lifting frame 552. Then the lifting frame 552 descends a predetermined distance so that the receiving unit 553 on the upper level corresponds to the output unit 554. At this time, the process of transporting the tray 900, loading the workpiece 800 on the tray, outputting the tray 900, and lowering the lifting frame 552 continues until each receiving unit 553 has received the workpiece 800. Only then can the blister tray 910 on the tray 900 be manually removed.

[0035] It should be noted that the power component 557 is a three-phase asynchronous motor, synchronous motor, servo motor, or other power component that can drive the output unit 554 to operate.

[0036] In some embodiments, the connecting transmission member 556 includes a connecting gear 556a, a rotating arm 556b, and a thrust cylinder 556c. The output unit 554 is provided with a first gear 554a, which can drive the first gear 554a to rotate. The receiving unit 553 is provided with a second gear 553a, which can drive the receiving unit 553 to operate. The rotating arm 556b is rotatably connected to the output unit 554, and the connecting gear 556a is rotatably connected to the rotating arm 556b. The connecting gear 556a meshes with the first gear 554a. One end of the thrust cylinder 556c is hinged to the frame 551, and the other end of the thrust cylinder 556c is hinged to the rotating arm 556b. The thrust cylinder 556c is used to drive the rotating arm 556b to rotate so as to drive the connecting gear 556a to revolve around the first gear 554a, thereby causing the connecting gear 556a to mesh with or disengage from the second gear 553a on the corresponding receiving unit 553. The term "revolution" refers to the fact that the connecting gear 556a always remains engaged with the first gear 554a, but the rotating arm 556b can drive the connecting gear 556a to revolve and roll on the first gear 554a. When the rotating arm 556b stops moving, the first gear 554a can drive the connecting gear 556a to rotate. When the connecting gear 556a engages with the second gear 553a, the power component 557 can simultaneously drive the output unit 554 and the receiving unit 553 to operate.

[0037] In some embodiments, both the receiving unit 553 and the output unit 554 are synchronous belts. Each receiving unit 553 and output unit 554 has a drive shaft 558 at one opposite end. The synchronous belt is wound around the corresponding drive shaft 558, which drives the corresponding synchronous belt to rotate. The drive shaft 558 of the output unit 554 is connected to a power component 557, which drives the drive shaft 558 of the output unit 554 to rotate, thereby driving the corresponding synchronous belt to rotate. A first gear 554a is disposed in the output unit 554. On the drive shaft 558, the rotating arm 556b is rotatably connected to the drive shaft 558 of the output unit 554.
