Description

Technical Field

[0001] The present invention relates to the technical field of switch panel production, in particular to a production line for household switches. Background Art

[0002] As consumers' demands for switch panels increase, they often require additional decorative processing, such as hot stamping. Especially for products such as switch panels that are produced in large quantities, production efficiency is particularly important.

[0003] Because the production efficiency of the hot stamping process is different from that of the assembly process, the existing hot stamping process for switch panels generally involves first performing hot stamping on the components that need hot stamping in batches, and then manually transferring them to the assembly equipment for assembly production. This results in a long production cycle. Summary of the Invention

[0004] The technical problem to be solved by the embodiments of the present invention is to provide a production line for household switches, which can automatically and continuously complete the hot stamping and assembly processes of the switch panel with high production efficiency.

[0005] To solve the above technical problems, an embodiment of the present invention provides a production line for household switches, comprising a hot stamping device for hot stamping keys, a switch assembly device for assembling keys and a panel holder, and a key dispensing device for transporting and arranging keys. The keys processed by the hot stamping device are passed through the key dispensing device in a preset quantity and arrangement state to be received by the switch assembly device.

A key waiting station for limiting the position of the key is formed on the transport mechanism between the side pressing edge, the side guard edge and the limit strip, so that the switch assembly device can remove the key on the key waiting station at a fixed point.

[0010] As an improvement to the above solution, the key feeding mechanism includes a hot stamping workpiece rotating disk and a workpiece translation clamping mechanism for moving the key to the transport mechanism, and the hot stamping workpiece rotating disk is provided with a key mold for fixing and placing the key;

[0011] The key mold passes through the hot stamping station of the hot stamping device and the hot stamping clamping station of the workpiece translation clamping mechanism in sequence through the hot stamping workpiece rotating disk, so that the key placed on the key mold is sequentially hot stamped and removed by the workpiece translation clamping mechanism.

[0012] As an improvement to the above solution, the stop top pressure block and the lifting baffle are combined into a partition mechanism for controlling the passage of the key, and the partition mechanism is provided with at least one;

[0015] The key mold on the ornament rotating disk passes through the ornament station of the ornament assembly device and the ornament clamping station of the key transfer mechanism in sequence through the ornament rotating disk.

[0016] As an improvement to the above solution, the ornament assembly device includes a swing arm for receiving the ornament, a swing arm driving mechanism for driving the swing arm to swing, and a swing arm lifting mechanism, wherein the swing arm is mounted on the swing arm lifting mechanism via the swing arm driving mechanism so as to be driven to move up and down by the swing arm lifting mechanism;

[0017] The swing arm is swung toward the decoration feeding place and the decoration workpiece respectively through the swing arm driving mechanism to move the decoration at the decoration feeding place to the decoration workstation.

[0018] As an improvement to the above solution, one end of the swing arm is connected to the swing arm drive mechanism, and the other end is provided with a notch for receiving the decorative part;

[0019] A negative pressure channel for connecting to a negative pressure pipeline is provided in the swing arm, and the negative pressure channel is communicated with the notch.

[0020] As an improvement of the above solution, the key transfer mechanism includes a workpiece translation clamping mechanism and a rotation buffer transfer mechanism;

[0021] The rotary cache transfer mechanism includes a rotary arm and a rotary arm driving mechanism for driving the rotary arm to rotate, and key cache molds for placing keys are provided at both ends of the rotary arm;

[0022] The workpiece translation clamping mechanism is provided on both sides of the rotary cache transfer mechanism to respectively move the buttons on the ornament rotary disk to the button cache mold and move the buttons on the button cache mold to the button mold on the hot stamping workpiece rotary disk.

[0023] As an improvement of the above solution, the workpiece translation clamping mechanism includes a guide rail frame provided with a translation slide rail, a slide rail seat provided on the translation slide rail, and a first driving mechanism for driving the slide rail seat to move;

[0024] The slide rail seat is provided with a lifting mechanism and a clamping claw driven to move up and down by the lifting mechanism.

[0025] As an improvement of the above-mentioned scheme, the hot stamping device includes a hot stamping lifting frame, a hot stamping roller arranged on the hot stamping lifting frame, a heating device for heating the hot stamping roller and a hot stamping lifting mechanism. The hot stamping lifting frame is provided with a coiling mechanism for retracting and releasing the hot stamping tape. The coiling mechanism is arranged corresponding to the hot stamping roller so that the hot stamping coil released by the coiling mechanism passes between the hot stamping roller and the hot stamping station, and the hot stamping lifting mechanism drives the hot stamping lifting frame to move toward the hot stamping station.

[0026] As an improvement to the above solution, the switch assembly device includes an assembly workpiece rotating disk provided with a plurality of assembly molds, and a panel assembly device. The workbench is provided with a plurality of assembly stations for the panel assembly device to work. The assembly molds rotate along with the assembly workpiece rotating disk to circulate through each of the assembly stations.

[0027] The assembly mold is provided with a key station for placing keys and a base station for placing the panel seat;

[0028] The panel assembly device includes a component transport mechanism, an accessory assembly mechanism, and a lifting pressure head for moving the buttons and the panel seat into corresponding stations respectively. The assembly mold passes through the component transport mechanism, the accessory assembly mechanism, and the lifting pressure head in sequence. The button on the button station is moved to the panel seat on the base station through the accessory assembly mechanism to be pressed down by the lifting pressure head.

[0029] The keys on the key waiting station are moved to the key station of the assembly mold through the component carrying mechanism.

[0030] The implementation of the present invention has the following beneficial effects:

[0031] An embodiment of the present invention discloses a production line for household switches, comprising a hot stamping device, a switch assembly device for assembling keys and a panel holder, and a key dispensing device for transporting and arranging keys. The keys processed by the hot stamping device pass through the key dispensing device in a preset quantity and arrangement state to be received by the switch assembly device, thereby coordinating the problem of different production efficiencies between the switch assembly device and the hot stamping device.

[0032] The key arrangement device includes a key loading mechanism, a transport mechanism and an arrangement mechanism. The keys processed by the hot stamping device are moved to the transport mechanism through the key loading mechanism so that the hot stamped keys can be cached on the transport mechanism.

[0033] The arrangement mechanism includes a limit bar, a stop and top pressure block, a lifting baffle for blocking the movement of the key, and a positioning top member provided on both sides of the transport mechanism. The positioning top member includes a side pressure edge for pressing the key toward one side of the limit bar and a side retaining edge for blocking the movement of the key. The side pressure edge presses against the limit bar. The side pressure edge, the side retaining edge, and the limit bar form a key waiting station on the transport mechanism that defines the position of the key, so that the switch assembly device can remove the key on the key waiting station at a fixed point.

[0034] The stopping top pressure block, the lifting baffle and the positioning top piece are arranged in sequence along the transport direction of the transport mechanism. Therefore, when the key on the key-taking station is taken away, the lifting baffle is raised to release the key between the stopping top pressure block and the lifting baffle. At the same time, the stopping top pressure block presses the corresponding key sideways to limit the movement of the key, thereby preventing the subsequent key from entering between the stopping top pressure block and the lifting baffle before the lifting baffle falls.

[0035] The key released by the lifting baffle will be stopped by the extended side baffle, and under the side pressure of the side pressing edge, the key will eventually be constrained in the key waiting position. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] In order to make the objectives, technical solutions and advantages of the present invention more clear, the present invention will be described in further detail below with reference to the accompanying drawings.

[0044] See also Figure 1 The embodiment of the present invention provides a production line for household switches, comprising a hot stamping device 1 for hot stamping keys, a switch assembly device 2 for assembling keys and a panel seat, and a key dispensing device 3 for transporting and arranging keys. The keys processed by the hot stamping device 1 are passed through the key dispensing device 3 in a preset quantity and arrangement state to be received by the switch assembly device 2.

[0045] The key arrangement device 3 includes a key loading mechanism 31, a transport mechanism 32, and an arrangement mechanism provided on the transport mechanism 32. The keys processed by the hot stamping device 1 are moved to the transport mechanism 32 via the key loading mechanism 31.

[0046] The arrangement mechanism includes a limit bar 33, a stop and push block 34, a lifting baffle 35 for blocking the movement of the key, and a positioning top piece 36, which are arranged on both sides of the transport mechanism 32. The stop and push block 34, the lifting baffle 35 and the positioning top piece are arranged in sequence along the transport direction of the transport mechanism 32.

[0047] The stop pressing block 34 limits the movement of the key by pressing the key toward the limit bar 33 on one side;

[0048] The positioning top member 36 includes a side pressure edge 361 for pressing the key toward one side of the limit strip 33 and a side retaining edge 362 for blocking the movement of the key. The side pressure edge 361 presses toward the limit strip 33. A key waiting station for limiting the key position is formed on the transport mechanism 32 between the side pressure edge 361, the side retaining edge 362 and the limit strip 33, so that the switch assembly device 2 can remove the key on the key waiting station at a fixed point.

[0049] Specifically, the key loading mechanism 31 includes a hot stamping workpiece rotating disk 311 and a workpiece translation clamping mechanism 4 for moving the key to the transport mechanism 32. The hot stamping workpiece rotating disk 311 is provided with a key mold 3111 for fixing and placing the key.

[0050] The button mold 3111 passes through the hot stamping station of the hot stamping device 1 and the hot stamping clamping station of the workpiece translation clamping mechanism 4 in turn through the hot stamping workpiece rotating disk 311, so that the button placed on the button mold 3111 is hot stamped and taken away by the workpiece translation clamping mechanism 4 in turn.

[0051] See also Figure 2 and Figure 3 The workpiece translation and clamping mechanism 4 includes a guide rail frame 41 equipped with a translation rail 42, a rail seat 43 mounted on the translation rail 42, and a first drive mechanism 44 for driving the rail seat 43. A clamping jaw lifting mechanism 45 is mounted on the rail seat 43, and a clamping jaw 46 is driven by the clamping jaw lifting mechanism 45. Driven by the first drive mechanism 44, the clamping jaw 46 moves back and forth along the translation rail 42 between the transport mechanism 32 and the hot stamping clamping station. Furthermore, driven by the clamping jaw lifting mechanism 45, the clamping jaw 46 can grasp a key to separate it from the key mold 3111.

[0052] It should be noted that the stopper and pressure block 34, the lifting baffle 35, and the positioning member 36 are all equipped with drive mechanisms, which can be pneumatic telescopic rod mechanisms, electric push rods, or screw transmission mechanisms. These drive mechanisms are all conventional technologies, and their structural principles are not detailed here. Correspondingly, the first drive mechanism 44 and the gripper lifting mechanism 45 can also be pneumatic telescopic rod mechanisms, electric push rods, or screw transmission mechanisms. The transport mechanism 32 is preferably a belt transport mechanism.

[0053] Preferably, the driving mechanisms of the stopping and pressing block 34 , the lifting baffle 35 and the positioning top member 36 are pneumatic telescopic rod mechanisms, and the first driving mechanism 44 and the clamping jaw 46 lifting mechanism 45 are both pneumatic telescopic rod mechanisms.

[0054] Furthermore, for ease of description, the stopper and pressure block and lift plate 35 are combined to form a partitioning mechanism for controlling key access. Within each partitioning mechanism, space is left between the stopper and pressure block 34 and the lift plate 35 to accommodate at least one key. Therefore, this space can be adjusted based on the size of the keys and the number of keys required to be released at a time. Similarly, when the partitioning mechanism is used to control access to a panel holder or other component, this space can accommodate at least one panel holder or corresponding component.

[0055] Therefore, in order to improve the overall assembly efficiency of the switch panel, at least one partitioning mechanism is provided, and the number of partitioning mechanisms provided can be adjusted according to the assembly efficiency of the switch assembly 2. Thus, the buttons can be moved to the positioning top member 36 according to the required number and spacing.

[0056] Accordingly, the number of positioning members 36 is equal to the number of separating mechanisms. Based on the orderly and spaced release of the separating mechanisms by the keys, the positioning members 36 can be extended in an orderly manner to respectively constrain the keys released by each separating mechanism to their respective preset key access positions. This enables the switch assembly device 2 to achieve assembly conditions for accurately accessing multiple keys at a time.

[0057] Switch panels on the market are typically equipped with a luminous coating or luminous particles. However, the luminous coating can fade and have a limited lifespan. Furthermore, the cost of luminous particles, their small size, and the difficulty of installation lead to low production efficiency and high costs for these switch panels.

[0058] So see Figure 4 The embodiment of the present invention further includes a decoration installation machine 5 for installing decorations on buttons. The decoration installation machine 5 includes a decoration assembly device 51 for installing decorations on buttons, a decoration rotating disk 52, and a button transfer mechanism 53 for transferring buttons on the decoration rotating disk 52 to the hot stamping workpiece rotating disk 311. The decoration rotating disk 52 is provided with the button mold 3111.

[0059] The button mold 3111 on the ornament rotating disk 52 passes through the ornament station of the ornament assembly device 51 and the ornament clamping station of the button transfer mechanism 53 in sequence via the ornament rotating disk 52. Accordingly, the ornament can be a luminous particle.

[0060] See also Figure 5 In terms of assembling the ornament and the button, the ornament assembly device 51 includes a swing arm 511 for receiving the ornament, a swing arm driving mechanism 512 for driving the swing arm 511 to swing, and a swing arm lift 513. The swing arm 511 is mounted on the swing arm lift 513 via the swing arm driving mechanism 512 so as to be lifted and lowered by the swing arm lift 513.

[0061] The swing arm 511 is swung toward the trim feeding area and the trim working station via the swing arm driving mechanism 512 to move the trim from the trim feeding area to the trim working station. The trim feeding area may be equipped with a vibration plate specifically for trims to provide the trim to the swing arm 511 at a fixed point at the trim working station.

[0062] To access the decorative component, one end of the swing arm 511 is connected to the swing arm drive mechanism 512, and the other end is provided with a notch 514 for receiving the decorative component. When the notch 514 is located at the decorative component station, the opening of the notch 514 faces upward to accommodate the entry of the decorative component. Then, driven by the swing arm drive mechanism 512, the notch 514 swings to the decorative component station, where it faces downward and is pressed down by the swing arm lifting mechanism 513, pressing the decorative component into the corresponding assembly position on the button. Furthermore, to prevent the decorative component from falling during the swinging and flipping process, a negative pressure channel for connecting to a negative pressure pipeline is provided within the swing arm 511. This negative pressure channel communicates with the notch 514 to prevent the decorative component from falling through suction.

[0063] Furthermore, the key transfer mechanism 53 includes a workpiece translation clamping mechanism 4 and a rotary cache transfer mechanism; the rotary cache transfer mechanism includes a rotary arm 531 and a rotary arm driving mechanism 532 for driving the rotary arm 531 to rotate, and key cache molds 533 for placing keys are provided at both ends of the rotary arm 531;

[0064] The workpiece translation gripping mechanisms 4 are located on either side of the rotary buffer transfer mechanism to respectively transfer the keys on the ornament rotating disk 52 to the key buffer mold 533 and the keys on the key buffer mold 533 to the key mold 3111 on the hot stamping workpiece rotating disk 311. The provision of these rotary buffer transfer mechanisms simplifies the coordination and debugging between the ornament installation machine 5 and the hot stamping device 1, eliminating the need for fully synchronized operation between the ornament rotating disk 52 and the hot stamping workpiece rotating disk 311. If the workpiece translation gripping mechanisms 4 are used for round-trip transfer, the longer the distance between the ornament assembly device 51 and the hot stamping device 1, the longer the key transfer cycle, which in turn limits the efficiency of both the ornament assembly machine and the hot stamping device 1.

[0065] Preferably, the driving mechanism of the rotating arm 531 is a motor, and the middle portion of the rotating arm 531 is mounted on the output shaft of the motor.

[0066] See also Figure 6 The hot stamping device 1 includes a hot stamping lifting frame 11, a hot stamping roller 12 arranged on the hot stamping lifting frame 11, a heating device for heating the hot stamping roller 12 and a hot stamping lifting mechanism 111. The hot stamping lifting frame 11 is provided with a coiling mechanism for retracting and releasing the hot stamping tape. The coiling mechanism is arranged corresponding to the hot stamping roller 12 so that the hot stamping coil released by the coiling mechanism passes between the hot stamping roller 12 and the hot stamping station, and the hot stamping lifting mechanism drives the hot stamping lifting frame 11 to move toward the hot stamping station.

[0067] The hot pressing lifting frame 11 is provided with a hot pressing adjustment mechanism for adjusting the position of the hot pressing roller 12. The hot pressing adjustment mechanism includes a hot pressing seat 13, a rotating shaft 14 mounted on the hot pressing seat 13, a threaded sleeve 15 sleeved on the rotating shaft 14, and a fixed block 16 threadedly connected to the threaded sleeve 15. The hot pressing roller 12 is provided with a roller hole for the threaded sleeve 15 to pass through. The hot pressing roller 12 is clamped between the two fixed blocks 16 to limit the movement of the hot pressing roller 12, thereby achieving the fixation of the hot pressing roller 12. Accordingly, when the position of the hot pressing roller 12 needs to be adjusted, the fixed block 16 is twisted to move on the threaded sleeve 15, thereby changing the position of the restriction on the movement of the hot pressing roller 12. In addition, the hot pressing lifting frame 11 is provided with a rotating shaft drive mechanism for controlling the rotation of the rotating shaft 14, thereby controlling the rotation of the hot pressing roller 12.

[0068] The heating device includes a heat-insulating cover 17 covering the hot stamping roller 12 and a heating element 18 corresponding to the hot stamping roller 12. The heating element 18 is disposed within the heat-insulating cover 17 to heat the hot stamping roller 12. Furthermore, the shaft drive mechanism is configured to control the heated surface of the hot stamping roller 12 to face the hot stamping station, so that the surface, after a certain number of hot stampings, faces the heating element 18 for reheating, thereby ensuring effective hot stamping of the hot stamping roller 12. Preferably, the heating element 18 is a heating tube. The heating tube coil is arranged along the inner wall of the heat-insulating cover 17.

[0069] Preferably, the shaft driving mechanism can be a servo motor to directly drive the rotation of the ironing roller 12. More preferably, the rotation driving mechanism can indirectly drive the rotation of the ironing roller 12 through a sprocket transmission, thereby reducing the high temperature operation caused by the heat dissipation of the heating element 18 on the rotation driving mechanism.

[0070] The winding mechanism includes a drawing roller 19 for winding the hot stamping tape, a feeding roller 110 for placing the hot stamping tape roll, and a drawing drive mechanism for driving the drawing roller 19 to rotate. The drawing roller 19 and the feeding roller 110 are respectively arranged on both sides of the hot stamping lifting frame 11, and the hot stamping roller 12 is located between the drawing roller 19 and the feeding roller 110. Therefore, the movement of the hot stamping tape can be controlled by controlling the rotation of the drawing roller 19, coordinating with the rotation of the hot stamping workpiece rotating disk 311, so as to carry out the hot stamping work in an orderly manner. Preferably, the drawing drive mechanism can be a servo motor to directly drive the rotation of the drawing roller. More preferably, the drawing drive mechanism can indirectly drive the rotation of the drawing roller by sprocket drive or belt drive, so as to facilitate the drawing drive mechanism to select a suitable installation position on the hot stamping lifting frame 11.

[0071] See also Figure 7The switch assembly device 2 includes an assembly workpiece rotating disk 21 provided with a plurality of assembly molds 211, and a panel assembly device. The workbench of the switch assembly device is provided with a plurality of assembly stations for the working activities of the panel assembly device. The assembly molds 211 rotate along with the assembly workpiece rotating disk 21 to circulate through each of the assembly stations.

[0072] The assembly mold 211 is provided with a key station for placing keys and a base station for placing a panel seat;

[0073] The panel assembly device includes a component carrier mechanism 22, an accessory assembly mechanism 23, and a lifting head 24 for moving the buttons and the panel seat into corresponding stations respectively. The assembly mold 211 passes through the component carrier mechanism 22, the accessory assembly mechanism 23, and the lifting head 24 in sequence. The buttons on the button station are moved to the panel seat on the base station by the accessory assembly mechanism 23, and are pressed downward by the lifting head 24.

[0074] The keys on the key waiting station are moved to the key station of the assembly mold 211 through the component carrying mechanism 22 .

[0075] The component transport mechanism 22 and the accessory assembly mechanism 23 both include a transport translation mechanism 2a for traveling back and forth between workstations, a transport lifting mechanism 2b, and a 2c for receiving workpieces. The receiving head 2c is arranged on the transport lifting mechanism 2b to be driven by the lifting and lowering of the transport lifting mechanism 2b. The transport lifting mechanism 2b is arranged on the transport translation mechanism 2a to be driven by the translation of the transport translation mechanism 2a.

[0076] The transport and translation mechanism 2a includes a transport frame 2a1, a transport rail 2a2 mounted on the frame, a transport slide 2a3 mounted on the transport rail 2a2, and a translation transport and telescopic mechanism 2a4 for driving the transport slide 2a3. The transport slide 2a3 is provided with a boom 2a5 for suspending the transport and lifting mechanism 2b. The transport and lifting mechanism 2b includes a connector base plate 2b1 for mounting the receiving head 2c and a lifting and transport telescopic mechanism 2b2 for driving the connector base plate 2b1 in an upward and downward direction. The lifting and telescopic mechanism 2b2 is mounted on the boom 2a5 to allow the receiving head 2c to be suspended above the assembly mold 211.

[0077] Conventional components of the switch panel, such as buttons and panel seats, generally have a relatively flat surface for the suction cup to adsorb. Therefore, the connecting head 2c includes a connecting rod 2c1 and a suction cup 2c2. One end of the connecting rod 2c1 is connected to the connector substrate 2b1, and the other end is connected to the suction cup 2c2. Preferably, in order to facilitate the adjustment of the height position of the suction cup 2c2 to facilitate the normal adsorption process, the connecting rod 2c1 is a screw rod, and the connector substrate 2b1 is provided with a screw hole that is compatible with the screw rod. Therefore, by turning the knob of the connecting rod 2c1, the extension length of the suction cup 2c2 relative to the connector substrate 2b1 can be controlled. Preferably, the suction cup 2c2 can be equipped with a vacuum pump to enhance the adsorption force.

[0078] To make the present invention more compact, the number of panel assembly devices can be increased to improve assembly efficiency. This embodiment of the present invention also includes a fixed baseplate 25 for mounting the lifting and lowering head 24. The fixed baseplate 25 is positioned above the assembly workpiece rotating disk 21. The fixed baseplate 25 is smaller than the assembly workpiece rotating disk 21, so that the periphery of the assembly workpiece rotating disk 21 forms an exposed annular working area for positioning the assembly mold 211. The fixed baseplate 25 can be suspended above the assembly workpiece rotating disk 21 via a hanger (not shown). Correspondingly, the lifting pressure head 24 is equipped with a pressure head telescopic mechanism 241 for driving the lifting pressure head 24 to rise and fall, and the fixed base plate 25 is provided with a cantilever 251. The lifting pressure head 24 is installed on the cantilever 251 through the pressure head telescopic mechanism 241, so that the lifting pressure head 24 is suspended at a preset position in the annular working area, so that the lifting pressure head 24 can press down the assembly mold 211 on the annular working area, thereby pressing the combined workpiece on the assembly mold 211, such as the pressing between the button and the panel seat.

[0079] It should be noted that, compared to buttons, the panel base does not require hot stamping, decorative assembly, or other processing. Therefore, the panel base can be placed on the base station of the assembly mold 211 and loaded manually. Alternatively, an additional panel arrangement device can be added to achieve the panel base loading process.

[0080] The panel arrangement device includes the above-mentioned transport mechanism 32 and an arrangement mechanism arranged on the transport mechanism 32. The automatic loading of the panel seat can be completed by simply placing the panel seat on the transport mechanism 32. Its arrangement principle is the same as the working principle of the above-mentioned button arrangement device, and its structural principle will not be described here one by one.

[0081] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
