Description

Technical Field

[0001] This utility model relates to the field of automation equipment technology, specifically to a terminal feeding mechanism for automatic assembly of DC brushed switches. Background Technology

[0002] In the production and assembly process of DC brushed switches, the assembly of terminals and switch housing is one of the key steps. Currently, the loading of terminals in this process mainly relies on manual operation.

[0003] Specifically, operators need to manually pick up the terminals from the terminal storage area and then align them with the installation position on the switch housing for placement and initial fixation. During this process, due to the small size and delicate structure of the terminals, manual picking can easily result in unstable handling and positioning deviations, requiring a significant amount of time for adjustments each time the terminals are loaded.

[0004] Meanwhile, manual operation has inherent limitations in speed, making it difficult to achieve high-speed, continuous material loading. As production demands increase, this reliance on manual terminal loading severely restricts the rhythm of the entire switch assembly process, failing to meet the high-efficiency requirements of automated production, directly leading to low production efficiency and making it difficult to meet the needs of large-scale production.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0034] This utility model provides a terminal feeding mechanism for automatic assembly of DC brushed switches.

[0035] In this embodiment, refer to Figure 1-9 The terminal feeding mechanism for automatic assembly of the DC brushed switch includes a frame 1, a switch housing vibration mechanism 2, a conveying track 3, and a terminal feeding mechanism 4. The terminal feeding mechanism includes a terminal vibration mechanism, a blocking mechanism 5, a positioning detection mechanism 6, a flipping mechanism, and a lateral movement mechanism.

[0036] The terminal vibration mechanism includes a terminal vibration disk 7 and a linear vibration feed rail 8 connected to the terminal vibration disk 7. The linear vibration feed rail 8 is provided with a terminal conveying groove 9, and the end of the terminal linear vibration feed rail is provided with a baffle hole 10 that connects to the terminal conveying groove.

[0037] The material blocking mechanism is fixed to the end of the linear vibrating feed rail, and the output end of the material blocking mechanism is connected to a material blocking rod 11, which is positioned directly opposite the material blocking hole 10.

[0038] The arrival detection mechanism is located at the tail of the terminal conveying groove and is used to detect whether the terminal has been conveyed to the designated position.

[0039] The flipping mechanism includes a rotary cylinder 12 and a receiving rod 13 connected to the output end of the rotary cylinder 12. The top of the receiving rod 13 is provided with a terminal receiving groove, and a detection hole 15 is provided on the receiving rod located on one side of the positioning detection mechanism.

[0040] The traversing mechanism is used to clamp and transfer the terminal 16 on the flipping mechanism and install it into the switch housing 17 on the conveying track.

[0041] In the above technical solution, the terminal feeding mechanism consists of a frame, a switch housing vibration mechanism, a conveying rail, and a terminal feeding mechanism. In the terminal feeding mechanism, the vibration mechanism conveys terminals via a vibrating plate and the conveying groove of the vibration feeding rail. The blocking mechanism's blocking rod blocks the preceding terminal through a blocking hole until the last terminal is received by the terminal receiving groove of the flipping mechanism. A positioning detection mechanism (such as a conventional infrared detection device or photoelectric detection device in automated equipment) detects whether the terminal is in position. The receiving rod of the flipping mechanism receives the terminal through the receiving groove, and a rotary cylinder drives it to flip. A traversing mechanism clamps, transfers, and installs the flipped terminal into the switch housing. All mechanisms work together to complete the automatic feeding and assembly of the terminals.

[0042] This achieves a fully automated process from terminal feeding to installation onto the switch housing, eliminating the need for manual intervention, solving the problem of low efficiency in manual feeding, significantly improving the assembly efficiency of DC brushed switches, and meeting the needs of large-scale production.

[0043] The material blocking mechanism is a cylinder, and the output end of the cylinder is connected to the material blocking rod.

[0044] Specifically, the linear vibrating feed rail includes a base plate 18, a cover plate 19, a base 20, and a base cover 21. A terminal conveying groove for conveying terminals is formed between the base plate and the cover plate, and between the base and the base cover. An installation step 22 for installing a positioning detection mechanism is provided on the side of the base away from the base plate.

[0045] In this embodiment, the linear vibrating feed rail consists of a base plate, a cover plate, a base, and a base cover, forming terminal conveying grooves between each pair to ensure stable terminal conveying. The mounting steps on the base provide a stable mounting position for the arrival detection mechanism, ensuring that the detection mechanism can accurately align with the terminal conveying path, improving the accuracy of terminal arrival detection, and further ensuring the smooth progress of subsequent processes.

[0046] Specifically, the transverse movement mechanism includes a column 23, a horizontal plate 24 fixed on the column 23, a transverse movement cylinder 25 fixed on the horizontal plate 24, a vertical plate 26 connected to the horizontal plate via a slide rail slider assembly, a lifting cylinder 27 fixed on the vertical plate, an output block 28 connected to the vertical plate via a slide rail slider assembly, a cylinder clamp 29 fixed on the output block, and a terminal positioning foot 30 fixed on the cylinder clamp. The bottom of the terminal positioning foot is provided with a bayonet 31 for terminal insertion. The output end of the transverse movement cylinder is connected to the vertical plate, and the output end of the lifting cylinder is connected to the output block.

[0047] In this embodiment, in the lateral movement mechanism, the lateral movement cylinder drives the vertical plate to move along the horizontal plate, achieving lateral displacement and moving the terminal from one side of the terminal vibration mechanism to the side of the conveying track. The lifting cylinder drives the output block to lift and lower the cylinder clamp and the terminal positioning foot. After the terminal moves into the switch housing on the side of the conveying track, the lifting cylinder presses the terminal into the switch housing. The positioning foot's locking jaws secure the positioning terminal, improving its stability. Through the coordination of lateral movement, lifting, and clamping actions, the transfer and pressing installation of the terminal are completed.

[0048] Specifically, it also includes an assembly base plate 32, on which the base and column are fixed, and the rotary cylinder is fixed to the assembly base plate via a cylinder plate 33.

[0049] In this embodiment, the assembly base plate fixes the base and column, and the rotary cylinder is also fixed to the assembly base plate via a cylinder plate, making the linear vibrating feed rail, lateral movement mechanism, and tilting mechanism a single integrated structure. This reduces vibration and displacement deviation of each component during operation, ensures the coordination accuracy between mechanisms, improves the reliability of equipment operation, and extends the service life of the equipment.

[0050] Specifically, a limit block 34 is provided above the cylinder plate.

[0051] In this embodiment, a limiting block is provided above the cylinder plate. When the rotary cylinder drives the receiving rod to rotate, the limiting block will block and limit the receiving rod when it rotates to a specific position.

[0052] Specifically, the receiving rod includes a main rod 35 and a secondary rod 36, which are fixed together by bolts, forming the aforementioned terminal receiving groove between the main rod and the secondary rod.

[0053] In this embodiment, the receiving rod consists of a main rod and a secondary rod fixed together by bolts, forming a terminal receiving groove between them. This allows the size of the receiving groove to be changed by adjusting the bolts according to the terminal size.

[0054] The working principle of this device is as follows:

[0055] After the terminal vibration mechanism is started, the terminal vibrating plate arranges the terminals in an orderly manner and feeds them into the terminal conveying groove of the linear vibration feed rail. The terminals move along the conveying groove towards the end. When the terminals are conveyed to the arrival detection mechanism, the arrival detection mechanism detects whether the terminals have reached the designated position.

[0056] During terminal conveying, the blocking mechanism controls the movement of the blocking rod, which blocks the terminals through the blocking hole. When the receiving rod of the flipping mechanism is not flipped over to receive the terminal, it prevents the terminal from sliding out of the conveying trough. When the receiving rod of the flipping mechanism flips over to receive the terminal, it prevents the penultimate terminal from continuing to advance.

[0057] The rotating cylinder of the flipping mechanism drives the receiving rod to move, so that the terminal receiving groove at the top of the receiving rod is aligned with the tail of the terminal conveying groove. The terminal enters the terminal receiving groove under the push of the subsequent terminal or its own inertia.

[0058] Subsequently, the rotary cylinder operates, causing the receiving rod to rotate and flip the terminal to a position that meets the installation requirements.

[0059] Finally, the lateral movement mechanism is activated, clamping the terminal that has been adjusted in position on the flipping mechanism, transferring it from the receiving rod, and installing it into the switch housing on the conveying track, thus completing the assembly of the terminal and the switch housing.

[0060] Through the coordinated efforts of the aforementioned mechanisms, an automated process from terminal feeding to installation has been achieved, eliminating the need for manual intervention and significantly improving the efficiency and accuracy of terminal assembly.

[0061] Attention all technical personnel: Although this utility model has been described according to the specific embodiments above, the concept of this utility model is not limited to this utility model. Any modification that utilizes the concept of this utility model will be included within the scope of protection of this patent right.
