Description

Technical Field

[0001] This utility model belongs to the field of injection molding door panel production technology, and in particular relates to an injection molding door panel production line. Background Technology

[0002] In cabinet or box structures, injection-molded door panels typically achieve closure and locking via magnetic attraction. Therefore, during the injection molding process, mounting holes must be pre-drilled at specific locations on the door panel to embed magnets or magnetic conductors.

[0003] However, due to the requirements of the injection molding demolding process, door panels must have a draft angle. This design results in the side of the door panel with the mounting holes generally facing downwards after injection molding. This forces operators to flip each door panel before assembling magnets or magnetic conductors, adjusting the mounting holes to an easily accessible position before installation. However, frequent manual flipping is time-consuming and labor-intensive, resulting in high labor intensity for workers and low production efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, an injection molding door panel production line is provided that reduces the labor intensity of workers and improves production efficiency.

[0005] This utility model is achieved using the following technical solution: an injection-molded door panel production line, comprising:

[0006] A slide rail, on which a slide table is slidably connected;

[0007] The slide rail is provided with the following components along its conveying direction:

[0008] The door panel loading station is located at the first end of the slide rail. The door panel loading station includes a first lifting device for completing the loading of the door panel and a placement platform for receiving the door panel from the first lifting device.

[0009] A door panel flipping station is set up adjacent to the door panel loading station. It includes a flipping arm, which is used to perform a flipping operation during the process of transferring the injection-molded door panel on the placement table to the slide table, so that the mounting holes on the door panel are in a vertically upward position.

[0010] The installation station includes an installation assembly that automatically screws or presses magnets or magnetic conductors into the mounting holes.

[0011] The door panel unloading station, located at the end of the slide rail, is used to receive the installed injection-molded door panel. The door panel unloading station includes a second lifting device for unloading and transferring the door panel.

[0012] During the operation of the production line, the first lifting device transfers the injection-molded door panel to a placement table. Then, the flipping arm at the door panel flipping station transfers the injection-molded door panel from the placement table to a sliding table. During the transfer, the door panel is flipped so that the mounting holes are facing upwards. The sliding table then slides to the installation station, where the installation mechanism automatically screws or presses the magnet or magnetic conductor into the mounting holes. Finally, the sliding table slides to the installation station, where the second lifting device transfers the door panel for unloading, thus completing the assembly of the magnet or magnetic conductor on the entire injection-molded door panel.

[0013] This solution eliminates the need for workers to actively operate the door panel loading, flipping, magnet or magnetic conductor installation, and door panel cutting, reducing labor intensity and making production faster, easier, and more efficient.

[0014] Preferably, the flipping arm is equipped with a pneumatic suction cup, and the placement platform is equipped with a through groove for the flipping arm to pass through.

[0015] When the flipping arm is in standby mode, it is located below the placement platform, and the pneumatic suction cup is located in the clearance groove.

[0016] When performing the door panel transfer and flipping operation, the pneumatic suction cup adsorbs the door panel, and the flipping arm performs a flipping motion.

[0017] The pneumatic suction cups ensure good stability of the door panel during the flipping process, and the pneumatic suction method will not damage the injection-molded door panel.

[0018] Preferably, the height of the sliding table is lower than the height of the placement platform, so that after the pneumatic suction cup adsorbs the door panel and completes a 180° rotation, the door panel is horizontally suspended above the sliding table, and when the door panel is released, its lower end face does not interfere with the upper surface of the sliding table.

[0019] Due to the inherent structural height of the pneumatic suction cup, a natural height difference exists between the actual gripping position of the injection-molded door panel and the target placement plane after the flipping arm performs the door panel suction and flipping operation. This solution actively compensates for this height difference by pre-setting the upper surface of the slide table to be lower than the upper surface of the placement platform. This design ensures that when the flipping arm completes its 180° flipping motion and descends to the release position: the lower surface of the door panel automatically aligns with the upper surface of the slide table, achieving precise horizontal placement; eliminating spatial interference caused by the structural height of the pneumatic suction cup, and ensuring no risk of mechanical collision between the door panel and the slide table during release.

[0020] Preferably, the slide table is provided with fixing blocks extending along the length and width directions of the door panel, and clamping blocks moving along the length and width directions of the door panel, respectively; when the door panel is placed on the slide table, the clamping blocks clamp the door panel, so that the door panel is in close contact with the fixing blocks.

[0021] The above settings can be used to position the door panel, ensuring that the installation mechanism can smoothly screw or press the magnet or magnetic conductor into the mounting hole during subsequent installation, and that the door panel will not jump or shift when the magnet or magnetic conductor is installed.

[0022] Preferably, the door panel loading station is equipped with a first photoelectric sensing component to detect the position of the door panel on the placement table, so as to control the pneumatic suction cup to adsorb the door panel and the flipping arm to flip the door panel.

[0023] The slide is equipped with a second photoelectric sensor component to detect the positioning status of the door panel in order to control the clamping block to clamp the door panel.

[0024] The slide rail is equipped with a third photoelectric sensing component to control the sliding position of the slide table.

[0025] Preferably, the mounting assembly includes a mounting mechanism and a magnetically conductive vibrating feeding tray or a magnet separator;

[0026] The mounting mechanism includes a vertical drive device and a pressing or screwing device. The vertical drive device drives the pressing or screwing device to move vertically to press or screw the magnet or magnetic conductor into the mounting hole.

[0027] The vertical drive device includes a vertically movable push rod and a spring sleeved on the push rod. One side of the pressing device or screwing device is sleeved on the push rod and pressed against by the spring.

[0028] When the push rod moves downward, the pressing or screwing device can generate an adaptive buffered vertical displacement when installing the magnet or magnetic conductor to complete the installation of the magnet or magnetic conductor.

[0029] The above configuration ensures that the pressing or screwing device does not move rigidly during vertical movement. The spring provides adaptive space for the pressing or screwing device during vertical movement, preventing damage to the injection-molded door panel during magnet or magnetic guide component installation. The magnetic guide component vibratory feeding tray or magnet separator can be any existing mechanism capable of vibratory feeding of magnetic guide components, or any existing mechanism capable of separating magnets one by one.

[0030] Preferably, the magnetically conductive vibrating feeding tray includes:

[0031] Collection box, used to hold magnetic components;

[0032] The transport trough is located inside the collection box, and its channel width is configured to allow only a single row of magnetic conductors to pass through;

[0033] A rotating disc is located at the bottom of the collection box. Several material pockets are distributed around its inner wall. The magnetic conductive parts are poured into the transport trough by rotating the disc.

[0034] A swinging screening plate is suspended above the transport trough and uses a reciprocating swinging motion to screen out stacked magnetic conductive parts;

[0035] A vibration generating device is connected to a transport trough and directionally transports the magnetic conductive component to the area below the mounting mechanism.

[0036] Preferably, a V-shaped baffle is provided at one end of the transport trough corresponding to the rotating disk, and the V-shaped baffle is used to receive the magnetic conductive parts that fall from the material bag.

[0037] By setting up a V-shaped baffle, the falling magnetic components can be received more effectively.

[0038] Preferably, both the first and second lifting devices are pneumatic suction cup lifting devices.

[0039] Using a pneumatic suction cup to lift the door panel avoids damage to the door panel compared to clamping it with a claw.

[0040] Compared with the existing technology, the beneficial effects of this utility model are: the door panel loading, door panel flipping, magnet or magnetic conductive part installation and door panel unloading of this solution do not require workers to operate actively, reducing the labor intensity of workers, and making production faster and more labor-saving, thus improving production efficiency.

[0051] The present invention will now be further described with reference to the accompanying drawings and specific embodiments.

[0052] like Figure 9 As shown, Figure 9 The injection-molded door panel 100 required for this utility model has two mounting holes 101 on one side edge of the reverse side of the injection-molded door panel 100. The mounting holes 101 are used to install magnets or magnetic conductive parts.

[0053] like Figures 1 to 4 As shown, this embodiment discloses an injection-molded door panel production line, including a frame 1. A slide rail 44 is provided on the frame 1, and a slider 45 slides on the slide rail 44, supporting a slide table 4 so that the slide table 4 can slide onto the slide rail 44. A conveyor belt 43 is also provided below the slide table 4, and the lower end of the slide table 4 is connected to the conveyor belt 43. When the conveyor belt 43 rotates, the slide table 4 can slide on the slide rail 44. Along the conveying direction of the slide rail 44, a door panel loading station 2, a door panel flipping station 3, an installation station 5, and a door panel unloading station 6 are sequentially arranged.

[0054] like Figure 3As shown, the door panel loading station 2 is located at the first end of the slide rail 44. The door panel loading station 2 includes a first lifting device (not shown in the figure) for completing the loading of the door panel and a placement platform 21 for receiving the door panel from the first lifting device. The first lifting device adopts an existing pneumatic suction cup lifting device, which transports the door panel and places it on the placement platform 21 by adsorbing the door panel.

[0055] The door panel flipping station 3, located adjacent to the door panel loading station 2, includes a flipping arm 32 with a pneumatic suction cup 31. The flipping arm 32 achieves a 180° flip via a rotary cylinder 33. The placement table 21 has a through-hole 211 for the flipping arm 32 to pass through. When the flipping arm 32 is in standby mode, it is located below the placement table 21, and the pneumatic suction cup 31 is positioned within the through-hole. During the door panel transfer and flipping operation, the pneumatic suction cup 31 adheres to the door panel, and the flipping arm 32 performs a flipping motion to transfer the door panel onto the slide table 4. During the transfer, the door panel is flipped so that the mounting holes 101 of the door panel are vertically upward.

[0056] A first photoelectric sensing component 22 is provided below the placement platform 21. The first photoelectric sensing component 22 is located below the clearance groove 211 and detects the door panel's positioning status on the placement platform 21 in order to control the pneumatic suction cup 31 to adsorb the door panel and the flipping arm 32 to flip the door panel.

[0057] The slide table 4 slides to one side of the door panel flipping station 3 to receive the door panel from the door panel loading station 2. The height of the slide table 4 is lower than the height of the placement table 21, so that after the pneumatic suction cup 31 adsorbs the door panel and completes a 180° flip, the door panel is horizontally suspended above the slide table 4, and when the door panel is released, its lower end face does not interfere with the upper surface of the slide table 4.

[0058] The slide table 4 is provided with a fixing block 46 extending along the length and width directions of the door panel, and a clamping block 41 moving along the length and width directions of the door panel. The clamping block 41 is connected to a cylinder, and the cylinder moves the clamping block 41 along the length and width directions of the door panel, thereby clamping the door panel on the slide table 4 and making the door panel tightly against the fixing block 46.

[0059] The slide table 4 is equipped with a second photoelectric sensor component 42, which is used to detect the positioning status of the door panel in order to control the clamping block 41 to clamp the door panel.

[0060] like Figures 5 to 8As shown, this embodiment uses a method of installing magnetic components within mounting holes 101. The mounting station 5 includes a mounting assembly that automatically screws or presses the magnetic components into the mounting holes 101 of the door panel. The mounting assembly includes a mounting mechanism 52 and a vibrating loading tray 53 for the magnetic components. The vibrating loading tray 53 is located on one side of the slide rail 44, and the mounting mechanism 52 is slidably mounted on the transverse track 51 to install the magnetic components on the vibrating loading tray 53 onto the door panel.

[0061] The mounting mechanism 52 includes a vertical drive device and a screwing device. The vertical drive device is a vertical cylinder 524, and the screwing device is a motor 521. The vertical cylinder 524 can drive the motor 521 to move vertically, and the motor 521 is slidably mounted on a vertically positioned track. A drive rod 522 is connected to the output end of the motor 521, and a pneumatic suction head 523 is provided at the lower end of the drive rod 522. The pneumatic suction head 523 can attract the magnetic component, and the drive rod 522 can pass downward through the pneumatic suction head 523 to screw the magnetic component into the mounting hole 101 of the door plate. A push rod 525 is connected to the output end of the vertical cylinder 524, and a spring 526 is sleeved on the push rod 525. A slip ring 527 is fixed on one side of the motor 521, and the slip ring 527 is sleeved on the push rod 525 and pressed against by the spring 526. When push rod 525 moves downward, motor 521 can generate adaptive buffered vertical displacement during the installation of the magnetic guide component to complete the installation. In this embodiment, the magnetic guide component uses existing screws. In other embodiments, if bolts are used to install the magnet or magnetic guide component, the magnet or bolt needs to be pressed into the mounting hole 101 by pressing, in which case motor 521 is not required.

[0062] like Figure 7 and Figure 8As shown, the vibrating feeding tray 53 for magnetic components includes a collection box 531 for accommodating the magnetic components. The collection box 531 is arranged at a horizontal angle, and a rotating disk 532 is provided at the bottom of the collection box 531. A horizontally arranged transport trough 534 is provided in the axial direction inside the collection box 531. The width of the transport trough 534 is configured to allow only a single row of magnetic components to pass through. Several material pockets 5321 are distributed circumferentially on the inner wall of the rotating disk 532. The rotating disk 532 lifts the magnetic components at the bottom of the collection box 531 through the material pockets 5321 by rotating. When it reaches the highest position, the magnetic components are poured into the transport trough 534. The transport trough 534 is provided with V-shaped baffles 5341 at opposite positions to better receive the falling magnetic components. The collection box 531 is also equipped with a swing screening plate 533 suspended above the transport trough 534. The swing screening plate 533 swings through a linkage mechanism 5331, thereby screening out the magnetic conductive parts stacked in the transport trough 534. A vibration generating device 537 is provided at the end of the transport trough 534. The vibration generating device 537 causes the transport trough 534 to directionally transport the magnetic conductive parts to below the mounting mechanism. A horizontal cylinder 535 is provided at the end of the transport trough 534. The horizontal cylinder 535 drives the discharge block 536 to move. The discharge block 536 has a placement slot for placing a magnetic conductive part. The movement of the discharge block 536 can block the transport trough 534 and transport a magnetic conductive part directly below the pneumatic suction head 523.

[0063] If magnets are required to be installed, the entire magnetic guide vibrating feeding tray 53 needs to be replaced with any existing magnet separator, so as to separate individual magnets and transport them directly below the pneumatic suction head 523.

[0064] The slide rail 44 is equipped with a third photoelectric sensing component (not shown in the figure) to control the sliding position of the slide table 4, so that the door panel can be smoothly placed on the slide table 4, and at the same time, the magnetic conductor or magnet can be smoothly installed in the mounting hole 101 of the door panel.

[0065] The door panel unloading station 6 is equipped with a second lifting device. The second lifting device adopts the existing pneumatic suction cup lifting device, which picks up the door panel from the slide table 4 by adsorbing the door panel and realizes the unloading of the door panel.
