Description

Technical Field

[0001] This utility model relates to the field of wire production technology, and in particular to a terminal feeding and conveying device. Background Technology

[0002] In the field of wire processing and manufacturing, the assembly of wires and terminals is often involved. Precise feeding and positioning of terminals are crucial for ensuring crimping quality. Traditional terminal feeding methods generally rely on vibratory feeders or simple conveyor belts. While these devices can achieve batch transfer of terminals, they also have significant drawbacks: vibratory feeders use high-frequency vibration to arrange and transport terminals, but this can easily lead to unstable terminal postures, requiring subsequent complex positioning and handling devices for secondary positioning and handling to achieve terminal-wire connection; simple conveyor belts lack limiting structures, making terminals prone to displacement and overturning during transport, also requiring additional positioning mechanisms for secondary positioning and handling. Furthermore, equipping the equipment with vibratory feeders / conveyor belts or positioning and handling devices makes the overall structure larger, hindering compact design. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a terminal feeding and conveying device that can realize the orderly conveying of terminals one by one without the need for an additional positioning and handling mechanism, and can also simplify the equipment structure and achieve a compact design.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A terminal material transfer device includes: a terminal strip and a material transfer assembly. The terminal strip includes a limiting band and terminals mounted on the limiting band. The material transfer assembly includes a positioning fixture, a driving component, and a material transfer component.

The terminal strip is located inside the terminal strip positioning cavity. The clearance opening corresponds to a terminal mating area. The material transfer component is connected to the driving component, and the material transfer end of the material transfer component extends into the terminal strip positioning cavity. The driving component drives the material transfer component to move the terminals on the terminal strip one by one to the terminal mating area.

[0006] In one embodiment, a terminal strip positioning component is further included. The feeding assembly is connected to the discharge end of the terminal strip positioning component. A limiting channel is formed in the terminal strip positioning component, and the limiting channel is used to limit the conveying of the terminal strip.

The terminal strip positioning cavity includes a feeding positioning cavity and a discharging positioning cavity. The feeding positioning cavity is formed on the feeding positioning block, and the discharging positioning cavity is formed on the discharging positioning block. The feeding positioning block and the discharging positioning block are spaced apart to form the clearance opening. The material pusher is used to push the terminal strip from the feeding positioning cavity through the clearance opening and the discharging positioning cavity in sequence.

[0008] In one embodiment, a limiting strip positioning groove is formed on the terminal strip positioning cavity. The limiting strip positioning groove extends from the feeding side of the positioning fixture to the discharging side of the positioning fixture, and the limiting strip on the terminal strip is located in the limiting strip positioning groove.

[0009] In one embodiment, the material feeding component includes a material feeding fork, the driving component is connected to the material feeding fork, and the material feeding fork extends to one end of the terminal strip positioning cavity and has a clamping groove.

[0010] In one embodiment, guide ramps are provided on both sides of the clamping groove.

[0011] In one embodiment, two feeding forks are provided, and the two feeding forks are respectively located in the feeding positioning cavity and the discharging positioning cavity.

[0012] In one embodiment, the two feed forks are an integral structure.

[0013] In one embodiment, the positioning fixture is further provided with a fork relief groove and a fork relief hole.

[0015] Compared with the prior art, the present invention has at least the following advantages:

[0016] This utility model's terminal feeding and conveying device precisely limits the terminal strip's position using a positioning cavity within a positioning fixture, avoiding the terminal misalignment and flipping problems caused by traditional vibratory feeders or conveyor belts. Simultaneously, a feeding component moves the terminals one by one to the terminal mating area, reducing the cumulative error of alignment across multiple stages, thereby lowering the risk of misalignment and ensuring the mating accuracy between the terminals and the wire.

[0024] To facilitate understanding of this utility model, a more comprehensive description of this utility model will be given below with reference to the accompanying drawings.

[0025] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the terminal material transfer device includes: a terminal strip 1000 and a material transfer assembly 2200. The terminal strip 1000 includes a limiting band 1100 and wiring terminals 1200 installed on the limiting band 1100. The material transfer assembly 2200 includes a positioning fixture 2210, a driving member 2220 and a material transfer member 2230. The positioning fixture 2210 has a terminal strip positioning cavity 2211 and a clearance opening. The terminal strip positioning cavity 2211 is connected to the clearance opening. The terminal strip 1000 is located in the terminal strip positioning cavity 2211. The clearance opening corresponds to the terminal docking area. The material transfer member 2230 is connected to the driving member 2220, and the material transfer end of the material transfer member 2230 extends into the terminal strip positioning cavity 2211. The driving member 2220 is used to drive the material transfer member 2230 to move the wiring terminals 1200 on the terminal strip 1000 one by one to the terminal docking area.

[0026] It should be noted that the positioning cavity of the terminal strip in the positioning fixture 2210 further improves the positioning accuracy of the terminal strip 1000 during feeding, reduces the shaking and displacement of the strip during feeding, and avoids the terminal misalignment and flipping problems caused by traditional vibratory feeders or conveyor belts. The feeding component 2230 moves precisely under the drive of the drive component 2220, realizing the sequential feeding of the terminal strip 1200, ensuring that each terminal strip 1200 can pass through the avoidance port and enter the terminal mating area one by one. The purpose of setting the terminal mating area is to facilitate the material handling of the terminal crimping device, reduce the cumulative error of multi-stage alignment, thereby reducing the risk of misalignment and improving the quality of mating and crimping. In other words, the orderly feeding of terminals is achieved by sequential feeding, avoiding the congestion or misalignment problems that may occur in traditional feeding methods. At the same time, compared with traditional vibratory feeders and conveyor belts with complex positioning devices, it simplifies the equipment structure and facilitates compact equipment design. In this embodiment, the limiting strip is provided with positioning holes 1100, and the terminals are placed in the positioning holes 1100.

[0027] In one embodiment, the terminal feeding and transferring device 2000 further includes a terminal strip positioning member 2100. The feeding assembly 2200 is connected to the discharge end of the terminal strip positioning member 2100, and the feeding assembly 2200 is located near the terminal mating area. The terminal strip 1000 enters the feeding assembly 2200 through the terminal strip positioning member 2100. The feeding assembly 2200 is used to move the terminals 1200 on the terminal strip 1000 one by one to the terminal mating area.

[0028] It should be noted that the terminal strip positioning component 2100 reduces the offset and swaying of the terminal strip 1000 during the conveying process, ensuring that the terminal strip 1000 can be stably conveyed along a preset trajectory before entering the feeding assembly 2200. Simultaneously, setting the terminal mating area on the feeding assembly 2200 improves the positional accuracy of the terminals 1200 reaching the terminal mating area. Furthermore, the orderly conveying of terminals through sequential feeding avoids congestion or misalignment problems that may occur in traditional feeding methods. Compared to vibratory feeders or complex positioning devices, it simplifies the equipment structure and facilitates a more compact design.

[0029] In this embodiment, a limiting channel is provided on the terminal strip positioning member 2100, and the terminal strip 1000 is located within the limiting channel.

[0030] It should be noted that the purpose of setting up the limiting channel is to effectively prevent the material strip from shifting left and right, jumping up and down, or flipping during the conveying process, ensuring the straightness and stability of the terminal strip 1000 conveying, and reducing material picking errors caused by the unstable position of the terminal strip 1000. Specifically, the limiting channel includes a terminal limiting groove and a material strip limiting groove. The material strip limiting groove is used to limit the limiting strip 1100, and the terminal limiting groove is used to limit the wiring terminal 1200. In this way, by limiting different components on the terminal strip 1000 in sections, relative movement between the limiting strip 1100 and the wiring terminal 1200 can be avoided, preventing the wiring terminal 1200 from becoming loose or falling off the limiting strip 1100.

[0031] In one embodiment, a sensor 2110 is provided at the connection end between the terminal strip positioning member 2100 and the feeding assembly 2200. For example, the sensor 2110 is an infrared photodiode sensor 2110. By setting the sensor 2110 to detect and identify the position of the terminal strip 1000 in real time, the accuracy of the operation is ensured.

[0032] Please see Figure 3As shown, in one embodiment, the positioning fixture 2210 is provided with a feeding positioning block 2212 and a discharging positioning block 2213. The terminal strip positioning cavity 2211 includes a feeding positioning cavity and a discharging positioning cavity. The feeding positioning cavity is formed on the feeding positioning block 2212, and the discharging positioning cavity is formed on the discharging positioning block 2213. The feeding positioning block 2212 and the discharging positioning block 2213 are spaced apart to form a clearance opening. The material-pushing component 2230 is used to push the terminal strip 1000 from the feeding positioning cavity through the clearance opening and the discharging positioning cavity in sequence. In this way, the segmented positioning cavity design enhances the limiting effect on the terminal strip 1000 at different conveying stages, ensuring the stability of the movement of the limiting band 1100 whether it is carrying the terminal 1200 into the terminal docking area or carrying wire waste out of the terminal docking area, thus preventing positional displacement between the terminal 1200 or the wire waste and the limiting band 1100. In addition, position sensors are also provided on the feed positioning block 2212 and the discharge positioning block 2213 to identify the insertion position of the wire.

[0033] Please see Figure 3 and Figure 4 As shown, furthermore, a limiting strip positioning groove 2211a is formed on the terminal strip positioning cavity 2211. The limiting strip positioning groove 2211a extends from the feeding side of the positioning fixture to the discharging side of the positioning fixture, and the limiting strip 1100 on the terminal strip 1000 is located within the limiting strip positioning groove 2211a. In this way, the stability of the entire conveying trajectory of the limiting strip 1100 can be guaranteed, reducing the positional deviation or deformation of the limiting strip 1100 during movement, ensuring that the terminal 1200 smoothly enters the terminal mating area, and at the same time ensuring that the wire insulation waste smoothly leaves the equipment, avoiding interference with the normal operation of the equipment.

[0034] Please see Figure 5 and Figure 6 As shown, the material feeding component 2230 further includes a material feeding fork 2231, a driving component 2220 connected to the material feeding fork 2231, and a clamping groove 2231a is provided at one end of the material feeding fork 2231 extending to the terminal strip positioning cavity 2211. The driving component 2220 is used to drive the clamping groove 2231a on the material feeding fork 2231 to engage with one end of the terminal 1200 and drive the terminal strip 1000 to move forward.

[0035] It should be noted that the engaging structure between the clamping groove 2231a and the terminal block 1200 ensures reliable force transmission between the feeding fork 2231 and the terminal block 1200, avoids slippage during feeding, and ensures that the terminal belt 1000 can be effectively moved each time feeding, thereby improving the accuracy and stability of the movement of the terminal block 1200 and ensuring that each terminal block 1200 can move according to the preset distance.

[0036] In this embodiment, guide ramps are provided on both sides of the clamping groove 2231a. In this way, the guide ramps can guide one end of the terminal 1200 to slide smoothly into the clamping groove 2231a, reducing the difficulty of alignment between the feed fork 2231 and the terminal 1200, and also reducing the risk of damage caused by rigid collision between the clamping groove 2231a and the terminal 1200.

[0037] In one embodiment, two feeding forks 2231 are provided, located in the feeding positioning cavity and the discharging positioning cavity respectively. Thus, through the coordinated movement of the two feeding forks 2231, the feeding force is more evenly distributed on the terminal strip 1000, resulting in smoother transport of the terminal strip 1000. Furthermore, the positions of the two feeding forks 2231 are fixed, ensuring that the wiring terminal 1200 accurately enters the terminal mating area during feeding, improving the accuracy of crimping. In this embodiment, the two feeding forks 2231 are an integral structure.

[0038] Please see Figure 4 As shown, in one embodiment, the positioning fixture 2210 also has a fork-avoiding groove 2214 and a fork-avoiding hole. The fork-avoiding hole connects the fork-avoiding groove 2214 and the terminal strip positioning cavity 2211, so that the clamping groove 2231a of the fork 2231 extends through the fork-avoiding hole into the terminal strip positioning cavity 2211. Thus, the fork-avoiding groove 2214 and the fork-avoiding hole provide space for the movement of the fork 2231, preventing interference between the fork 2231 and the positioning fixture 2210 during swinging or moving, ensuring that the fork 2231 can move freely and smoothly, and guaranteeing the integrity and accuracy of the material handling action. Furthermore, the fork-avoiding hole provides a certain guiding effect on the movement of the fork 2231.

[0039] Please see Figure 5 and Figure 6 As shown, in one embodiment, the driving component 2220 includes a gear drive structure 2221, a feeding shaft 2222, a feeding drive block 2223, and a feeding slide shaft 2224. The feeding drive block 2223 has a shaft hole and a slide shaft hole 2223a. One end of the feeding shaft 2222 is connected to the gear drive structure 2221, and the other end of the feeding shaft 2222 passes through the shaft hole. The feeding slide shaft 2224 passes through the slide shaft hole 2223a, and the feeding component 2230 is connected to the feeding slide shaft 2224.

[0040] During the rotation of the gear drive structure 2221, the feeding drive block 2223 is driven to rotate and swing, causing the feeding component 2230 to swing and push the terminal strip 1000 forward to the terminal mating area. Specifically, the feeding drive block 2223 is similar to an eccentric wheel structure, with the sliding shaft hole 2223a offset from the rotating shaft hole. At the same time, the sliding shaft hole 2223a has an elongated structure, allowing the feeding sliding shaft 2224 to move along the sliding shaft hole 2223a. In addition, to prevent the feeding sliding shaft 2224 from falling off during the swinging process, a limiting protrusion is provided on the end of the feeding sliding shaft 2224 away from the feeding component 2230 to limit the feeding sliding shaft 2224.

[0041] It should also be noted that the gear drive structure 2221 includes a large gear 2221a, a connecting gear 2221b, and two drive gears 2221c. The connecting gear 2221b meshes with the two drive gears 2221c respectively, and the large gear 2221a meshes with the connecting gear 2221b. When the large gear 2221a rotates, it drives the connecting gear 2221b to rotate. There are also two sets of material feeding drive blocks 2223, material feeding shafts 2222, and material feeding sliding shafts 2224. The two material feeding drive blocks 2223 are connected to the two drive gears 2221c respectively through the material feeding shafts 2222. Therefore, when the connecting gear 2221b rotates, the two drive gears 2221c also rotate, thereby driving the two material feeding drive blocks 2223 to rotate and swing, and thus driving the material feeding component 2230 to swing. For example, when the feeder 2230 swings downwards, the clamping groove 2231a on the feeder fork 2231 gradually engages with one end of one of the terminals 1200 of the terminal strip 1000. Then, when the feeder 2230 swings upwards from the lowest point, the clamping groove 2231a on the feeder fork 2231 gradually moves away from the terminal 1200 and pushes one of the terminals 1200 into the terminal mating area. That is, when the feeder fork 2231 rotates and swings once, it moves one terminal 1200, ensuring the accuracy of the position of the terminal 1200 in the terminal mating area. Then the feeder fork 2231 returns to its original position.

[0042] It should also be noted that since the material-picking component is not always in a picking state, intermittent material picking can be achieved by setting an intermittent gear in conjunction with the rotary drive structure on the terminal stripping and crimping device. Alternatively, an intermittent gear can be used in conjunction with a geared motor to drive the gear drive structure to rotate, thus achieving intermittent material picking. In other words, one picking action is completed when a portion of the teeth on the intermittent gear meshes with the gear drive structure.

[0043] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
