Description

Technical Field

[0001] The utility model relates to the technical field of terminal processing, in particular to a chain-type terminal feeding device. Background Art

[0002] Ultrasonic welding uses high-frequency vibration waves to transmit to the surface of the wire harness and the terminal. Under pressure, the wire harness and the terminal surface rub against each other to form a fusion between the molecular layers.

[0003] Usually the incoming materials are loose terminals (the terminals exist independently), and the operator needs to manually place the loose terminals one by one into the fixed tooling for welding. This loading method is time-consuming and labor-intensive, and has safety hazards. Therefore, chain terminals are used to load materials using a tray (the terminal chain and the separator paper tape are wound on the tray at intervals). When loading the tray in the prior art, the terminal chain is generally only directly dragged by subsequent equipment to rotate the tray and release the terminal chain. This can easily cause the terminal chain to be subjected to excessive force, resulting in the terminal chain being broken, affecting processing efficiency.

[0004] In view of this, a chain terminal feeding device is urgently needed to solve the above problems. Summary of the Invention

[0005] In order to help solve the problems existing in the prior art, the present invention provides a chain-type terminal feeding device, which adopts the following technical solution: comprising: a material tray mechanism, a guiding mechanism, and a spacer paper tape winding mechanism, wherein the material tray mechanism includes a material tray, and the terminal chain and the spacer paper tape are both wound around the material tray, and the terminal chain and the spacer paper tape are arranged at intervals in the radial direction of the material tray;

[0006] The guide mechanism includes a guide, a floating plate, and a sensor. The guide is arranged below the material tray and is provided with a guide channel. The terminal chain is arranged in the guide channel. One side of the floating plate is rotatably connected to the guide. The floating plate is arranged above the feed end of the guide channel. The sensor is used to detect whether the floating plate rotates away from the feed end of the guide channel.

[0007] The separator paper tape winding mechanism includes a separator paper winding disk and a drive assembly. When the sensor detects that the floating plate rotates toward the side away from the feed end of the guide channel, the drive assembly drives the separator paper winding disk to rotate, so that the separator paper winding disk winds up the separator paper.

[0008] It is further characterized in that

[0009] The sensor is arranged on one side of the guide, the sensor is a slot-type optical coupler, and the floating plate is provided with a photoelectric baffle adapted to the slot-type optical coupler.

[0010] The guide is provided with a first arc-shaped plate below the feed end of the guide channel.

[0011] The floating plate is arc-shaped, and the floating plate and the first arc-shaped plate extend away from each other on a side away from the terminal chain conveyance.

[0012] The guide is provided with second arc-shaped plates above and below the discharge end of the guide channel, extending in directions away from each other.

[0013] A mounting bracket is provided on the guide.

[0014] The material tray mechanism also includes a first rotating shaft and two quick-release rods inserted in the circumferential direction of the first rotating shaft. The material tray is sleeved on the first rotating shaft, and the two quick-release rods are respectively arranged on both sides of the material tray.

[0015] The separator paper tape winding mechanism further includes a second rotating shaft and a nut. The separator paper winding disc is sleeved on the second rotating shaft, and the nut is threadedly connected to the suspension end of the second rotating shaft.

[0016] The driving component is a motor, and the output end of the motor is coaxially connected to the second rotating shaft.

[0017] A turning handle is provided on the nut.

[0018] The above structure of the utility model can achieve the following beneficial effects:

[0019] When in use, the terminal chain is tightened, the relative angle between the terminal chain and the guide changes, and a thrust is applied to the floating plate, causing the floating plate to rotate to the side away from the feed end of the guide channel. At this time, the sensor detects that the state of the floating plate has changed, and the drive component drives the separator paper reel to rotate, causing the separator paper reel to reel up the separator paper. The separator paper is tightened until the material tray rotates, and the terminal chain is released, so that the terminal chain returns to an untensioned state, ensuring the continuity of the feeding, avoiding the terminal chain from breaking, and ensuring the continuity of the processing.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0025] It should be noted that the terms "including" and "having" and any variations thereof in the specification and claims of the present invention and the above-mentioned drawings are intended to cover non-exclusive inclusions. For example, a process, method, apparatus, product or equipment that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or are inherent to these processes, methods, products or equipment.

[0026] The following is combined with Figure 1-3 The utility model is described in further detail.

[0027] Reference Figure 1-3, a chain terminal feeding device includes: a material tray mechanism, a guiding mechanism and a separator paper tape winding mechanism, the material tray mechanism includes a material tray 1, the terminal chain and the separator paper tape are both wound on the material tray 1, and the terminal chain and the separator paper tape are arranged at radial intervals on the material tray 1; the guiding mechanism includes a guide 2, a floating plate 3 and a sensor 4, the guide 2 is arranged below the material tray 1, a guide channel 21 is provided on the guide 2, the terminal chain is passed through the guide channel 21, one side of the floating plate 3 is rotatably connected to the guide 2, the floating plate 3 is arranged above the feeding end of the guide channel 21, and the sensor 4 is used to detect whether the floating plate 3 rotates toward the side away from the feeding end of the guide channel 21; the separator paper tape winding mechanism includes a separator paper winding disk 5 and a driving component, when the sensor 4 detects that the floating plate 3 rotates toward the side away from the feeding end of the guide channel 21, the driving component drives the separator paper winding disk 5 to rotate, so that the separator paper winding disk 5 When the terminal chain is in an untensioned state, the top side of the terminal chain does not contact the floating plate 3 or the force exerted by the terminal chain on the floating plate 3 is insufficient to rotate the floating plate 3. When the terminal chain is dragged during subsequent processing, the terminal chain is tightened. At this time, the relative angle between the terminal chain and the guide 2 changes, and a thrust is applied to the floating plate 3 to rotate the floating plate 3 to the side away from the feed end of the guide channel 21. At this time, the sensor 4 detects that the state of the floating plate 3 has changed, and the drive component drives the separator paper winding drum 5 to rotate, so that the separator paper winding drum 5 winds up the separator paper. The separator paper is tightened until the material tray 1 rotates and the terminal chain is released, so that the terminal chain is restored to an untensioned state, ensuring the continuity of the feeding, avoiding the terminal chain from being disconnected, and ensuring the continuity of the processing.

[0028] like Figure 1 and Figure 2 As shown, the sensor 4 is arranged on one side of the guide 2. The sensor 4 is a slot-type optical coupler. A photoelectric baffle 31 adapted to the slot-type optical coupler is provided on the floating plate 3. When the terminal chain is not tightened, the photoelectric baffle 31 is in the slot-type optical coupler. When the terminal chain is tightened, the floating plate 3 rotates to make the photoelectric baffle 31 leave the slot-type optical coupler, thereby completing the detection of the terminal chain status.

[0029] Further optimization is, Figure 2As shown, in order to avoid the terminal chain being cut off at the inlet and outlet of the guide channel 21, the guide 2 is provided with a first curved plate 22 below the feed end of the guide channel 21, and the floating plate 3 is curved. The floating plate 3 and the first curved plate 22 extend in directions away from each other on the side away from the terminal chain conveying, and the guide 2 is provided with second curved plates 23 extending in directions away from each other above and below the discharge end of the guide channel 21. In this way, the openings at both ends of the guide channel 21 are trumpet-shaped, which reduces the occurrence of the terminal chain being cut off and is also convenient for passing the terminal chain. At the same time, in order to facilitate the installation of the guide 2, a mounting bracket 24 is provided on the guide 2, and the guide 2 is mounted on the equipment through the mounting holes on the mounting bracket 24.

[0030] like Figure 1 As shown, the material tray mechanism also includes a first rotating shaft 6 and two quick-release rods 7 inserted in a circumferential direction on the first rotating shaft 6. The material tray 1 is sleeved on the first rotating shaft 6, and the two quick-release rods 7 are respectively arranged on both sides of the material tray 1. In this way, the convenience of disassembling and assembling the material tray 1 is improved by the two quick-release rods 7.

[0031] like Figure 3 As shown, in order to facilitate the disassembly and assembly of the separator paper reel 5, the separator paper tape reeling mechanism also includes a second rotating shaft 8 and a nut 9. The separator paper reel 5 is sleeved on the second rotating shaft 8, and the nut 9 is threadedly connected to the suspended end of the second rotating shaft 8. In this way, the separator paper reel 5 is clamped on the second rotating shaft 8 by screwing the nut 9, and the nut 9 is screwed to disengage the nut 9 from the second rotating shaft 8, so that the disassembly and assembly of the separator paper reel 5 can be completed. A turning handle is provided on the nut 9 to facilitate the screwing of the nut 9, and the driving component can be a motor, and the output end of the motor is coaxially connected to the second rotating shaft 8. In this way, the motor drives the second rotating shaft 8 to rotate, so that the separator paper reel 5 can be rotated.

[0032] In summary, when in use, the terminal chain on the material tray 1 is passed through the guide channel 21, and one end of the separator paper tape is wound on the separator paper winding disk 5. When the terminal chain is in an untightened state, the top side of the terminal chain does not contact the floating plate 3 or the force applied by the terminal chain on the floating plate 3 is insufficient to rotate the floating plate 3. When the terminal chain is dragged during subsequent processing, the terminal chain is tightened. At this time, the relative angle between the terminal chain and the guide 2 changes, and a thrust is applied to the floating plate 3 to rotate the floating plate 3 to the side away from the feed end of the guide channel 21 (upward rotation). At this time, the sensor 4 detects that the state of the floating plate 3 has changed, and the drive component drives the separator paper winding disk 5 to rotate, so that the separator paper winding disk 5 winds up the separator paper. The separator paper is tightened until the material tray 1 rotates and the terminal chain is released, so that the terminal chain is restored to an untightened state, ensuring the continuity of the feeding, avoiding the terminal chain from being disconnected, and ensuring the continuity of the processing.

[0033] This specific embodiment is merely an explanation of the present invention and is not intended to limit the present invention. After reading this specification, those skilled in the art may make non-creative modifications to this embodiment as needed. However, as long as such modifications are within the scope of the claims of the present invention, they are protected by patent law.
