Description

Technical Field

[0001] The invention relates to the technical field of wire conveying, and in particular to a wire conveying device and liquid level sensor manufacturing equipment. Background Art

[0002] As a medium for transmitting current or signals, wires are widely used in many workpieces with electrical components. The reliability and accuracy of wire assembly by welding methods such as soldering are crucial to the high-quality work of the workpiece, so there are high requirements for the reliability and accuracy of wire transmission to electrical components. Taking the existing contact-type liquid level sensor as an example, it uses the contacts on the reed that can rotate relative to the resistor to change the resistance value to achieve the output of the sensing signal. The liquid level sensor is generally configured in the fuel tank of a fuel vehicle, and the oil level in the tank is obtained according to the sensing signal, so that the car fuel gauge indicates the oil level accordingly. The liquid level sensor includes a wire, a frame and a resistor. The resistor is first assembled in the frame, and then a fixed end of each wire is transported to each preset wire end of the resistor, and each corresponding fixed end and preset wire end are welded and assembled by welding. However, in the prior art, for conveying the wires to the corresponding positions of the workpieces for assembly, either a traditional manual method is used, which has extremely low conveying efficiency, or a simple tooling semi-automatic method is used, which still requires a large degree of operator participation. Moreover, the operator is prone to bending the wires during the participation process, which has an adverse effect on the reliability and accuracy of the wire transportation. In particular, for the assembly of multiple wires relative to the same workpiece, the tooling semi-automatic method requires manual participation in the transfer of the relative positions of the workpiece and each wire, and it is difficult to ensure that each wire can be highly and accurately assembled with multiple different preset wire ends of the same workpiece.

[0003] In summary, the prior art has technical problems of low wire transmission efficiency, low assembly reliability and low precision. Summary of the invention

[0012] Furthermore, the flipping mechanism also includes a third rotating plate and a seventh driving cylinder. The seventh driving cylinder is arranged at one end of the second rotating plate relatively away from the clamping assembly. When the clamping assembly is rotated to a horizontal state by the rotating driver, the two piston rods of the seventh driving cylinder are extended so that the wire that has been assembled to the workpiece enters the gap between the two extended piston rods in the vertical direction. When the clamping assembly is further rotated to a vertical state by the rotating driver until it is another relative level, in the process of the wire following the rotation of the workpiece, the two piston rods are extended to prevent the wire from being deflected, so that the clamped workpiece is rotated to another wire conveying module so that the wire in the other wire conveying module is further assembled to the workpiece, and the two piston rods are shortened to prepare for the next extension.

[0029] refer to Figures 1 to 8As an object of the present invention, a wire conveying device is provided, including a wire feeding mechanism 1, a wiring mechanism 2, a wire pushing mechanism 3, a wire clamping mechanism 4 and a clamping mechanism 5. The wire feeding mechanism 1 includes a driving component 11, a wire taking-up component 12 and a limiting component 13 corresponding to the wire taking-up component 12, the wire taking-up component 12 is used to receive the wire 20, and the limiting component 13 limits the position of the wire 20. The wiring mechanism 2 includes a wiring groove 211, the driving component 11 drives the wire 20 to move above the wiring groove 211, and the limiting component 13 releases the limitation of the wire 20 so that the wiring groove 211 receives the wire 20 after falling. The wire pushing mechanism 3 is used to fix and push the wire 20 located in the wiring groove 211. The wire clamping mechanism 4 is used to clamp the wire 20 pushed therein by the wire pushing mechanism 3. The clamping mechanism 5 is used to install and clamp the workpiece to which the wire 20 is assembled. In the present invention, the workpiece is described by taking the liquid level sensor as an example. Therefore, the wire conveying device provided by the embodiment of the present invention realizes highly automated conveying of the wire 20 by setting various functional mechanisms that realize corresponding functions and cooperating with each other, and in particular, the wire feeding mechanism 1 can accurately accommodate and convey the wire 20, the wiring mechanism 2 can reliably receive the wire 20 conveyed and dropped by the wire feeding mechanism 1, the clamping mechanism 5 can reliably clamp the tooling to accurately align the free end of the wire 20 to be assembled, and the wire pushing mechanism 3 and the wire clamping mechanism 4 can cooperate to accurately deliver the free end of the wire 20 to the predetermined position of the tooling. Therefore, the wire conveying device of the present invention has the advantages of high conveying efficiency and high assembly reliability and accuracy for the wire 20.

[0030] Please refer to Figure 3 and Figure 4Specifically, the driving assembly 11 includes a first driving cylinder 111 and a first driving block 112 that are drivingly connected, a second driving cylinder 113 and a second driving block 114 that are drivingly connected, a support 115, a driving arm 116, a wire lifting rod 117 and a wire lifting arm 118. The support 115 is fixedly connected to the first driving block 112. The first driving cylinder 111 drives the first driving block 112 to reciprocate along a first direction toward or away from the wiring mechanism 2. The second driving cylinder 113 is arranged on the support 115. The driving arm 116 is fixedly connected to the second driving block 114. The wire lifting rod 117 is fixedly connected to the driving arm 116. One end of the wire lifting arm 118 is fixedly connected to the wire lifting rod 117 and the other end is initially located in the wiring groove 211. The wire take-up assembly 12 includes a wire take-up block 121 and a baffle 122. The wire take-up block 121 is provided with a wire take-up groove 1211 for accommodating the wire. The baffle 122 blocks the front end of the wire 20 and is arranged at the end of the wire take-up block 121 away from the wire take-up groove 1211. The limiting assembly 13 includes a first driver 131, a limiting block 132, and a pair of limiting clips 133 relatively located on both sides of the limiting block 132. A gap for a wire 20 to enter can be formed between the limiting block 132 and the limiting clips 133 adjacent thereto. The first driver 131 drives the pair of limiting clips 133 to approach or move away from each other relative to the sides of the adjacent limiting blocks 132, so that when they are relatively close, the pair of limiting clips 133 clamp and fix the wire 20 located in the gap. When they are relatively far away, a gap is formed to allow the wire 20 to enter. The driving arm 116 is fixedly connected to the first driver 131. After the pair of limit clamps 133 have clamped and fixed the wire 20, the second driving cylinder 113 drives the second driving block 114 to drive the driving arm 116 to rise along the second direction so that the limit clamp 133 and the wire lifting arm 118 jointly lift the wire 20 away from the wire receiving groove 1211, and the first driving cylinder 111 then drives the first driving block 112 to drive the support 115 to move toward the wiring mechanism 2 along the first direction, the first direction is perpendicular to the second direction, and after the wire 20 is located above the corresponding wiring groove 211, the first driver 131 drives the pair of limit clamps 133 to move away from each other, so that the wire 20 falls into the wiring groove 211. In this case, the pair of limit clamps 133 of the wire feeding mechanism 1 cannot be highly automated under the drive of the corresponding driving cylinder to both reliably clamp and release the wire 20 and accurately move to the top of the corresponding wiring groove 211, so that the wiring groove 211 accurately receives the falling wire 20.

[0031] Please refer to Figure 5Specifically, the wiring mechanism 2 includes a wiring board 21, a pair of guide posts 22, a support block 23 and a third driving cylinder 24. A wiring slot 211 is provided on the wiring board 21. The number of pairs of guide posts 22 is the same as the number of wire receiving slots 1211. The guide posts 22 restrict the movement of the wires 20 in the wiring slots 211 passing therethrough in the second direction. The support block 23 is located above the third driving cylinder 24. The wiring board 21 is relatively fixedly connected to the support block 23, and the third driving cylinder 24 drives the support block 23 to reciprocate parallel to the first direction. In this way, each wire 20 located on the wiring board 21 is not only reliably positioned by the wiring slot 211 and the guide posts 22, but can also be accurately transported to the clamping mechanism 4 and the clamping mechanism 5 by the third driving cylinder 24.

[0032] Please refer to Figure 5 Specifically, the wire pushing mechanism 3 includes a second driver 31, a holding block 32, a pair of holding plates 33 and a pair of driving frames 34. The pair of holding plates 33 are respectively fixed on a driving frame 34. A holding plate 33 is provided on each side of the holding block 32. A holding groove 331 connected to the wiring groove 211 is provided in each holding plate 33. When the wire receiving groove 1211 and the wire receiving groove 1211 are both set to two and two vertical planes parallel to the first direction pass through the pair of wire receiving grooves 1211 and the wire receiving groove 1211 respectively, a holding block 32 is provided at one end of the wiring board 21 closer to the wire clamping mechanism 4. The wire 20 passes through the holding plate 33 and the holding block 32 through the holding groove 331. The second driver 31 is arranged on the support block 23. The wiring board 21 passes through the second driver 31 and the fixed The column 25 is relatively fixedly connected to the support block 23, and the second driver 31 drives a pair of driving frames 34 to drive a pair of retaining plates 33 to approach or move away from the side of the retaining block 32 adjacent thereto, thereby correspondingly fixing or releasing the position of the wire 20. Alternatively, when the wire taking-up groove 1211 and the wire taking-up groove 1211 are both set to one and a vertical plane parallel to the first direction passes through the wire taking-up groove 1211 and the wire taking-up groove 1211 respectively, a pair of retaining plates 33 are respectively provided with a retaining groove 331 facing each other, and the wire 20 passes through the pair of retaining plates 33 through the two retaining grooves 331, and the second driver 31 drives a pair of driving frames 34 to drive a pair of retaining plates 33 to approach or move away from each other, thereby correspondingly fixing or releasing the position of the wire 20.

[0033] For both the wire taking-up slots 1211 and the wire taking-up slots 1211, there are two or only one of them, when the wiring mechanism 2 is located at the initial wiring position corresponding to the wiring slot 211 receiving the fallen wire 20 and the second driver 31 drives a pair of retaining plates 33 to be relatively close so that the position of the wire 20 remains fixed, the third driving cylinder 24 drives the wiring board 21 and the wire pushing mechanism 3 to move in the direction close to the wire clamping mechanism 4, so that the wiring mechanism 2 moves to the wire clamping receiving position. After the wire 20 is clamped by the wire clamping mechanism 4, the second driver 31 drives a pair of retaining plates 33 to be relatively away from each other so that the position of the wire 20 is released, and the third driving cylinder 24 drives the wiring board 21 and the wire pushing mechanism 3 to move in the direction away from the wire clamping mechanism 4 and return to the initial wiring position.

[0034] It should be noted that in the present invention, there are two wire conveying modules as described below, in which one of the wire conveying modules has one wire receiving groove 1211 of the receiving block and one wire receiving groove 1211 of the wiring board 21, and in the other wire conveying module, two wire receiving grooves 1211 of the receiving block and two wire receiving grooves 1211 of the wiring board 21 are provided. Therefore, the wire pushing mechanism 3 uses a pair of retaining plates 33 to maintain and release the position of the wire 20.

[0035] Please refer to Figure 6 and Figure 7Specifically, the wire conveying device clamping mechanism 4 includes a supporting plate 401, a first clamping plate 402 and a second clamping plate 403. The first clamping plate 402 of the wire conveying device is provided with two first clamping half holes 4021, and the second clamping plate 403 of the wire conveying device is provided with two second clamping half holes 4031. The first clamping half holes 4021 of the wire conveying device and the second clamping half holes 4031 of the wire conveying device are arranged alternately and oppositely. The first clamping plate 402 of the wire conveying device and the second clamping plate 403 of the wire conveying device are respectively connected to the first elastic member 404 by a first elastic member 404. The support plate 401 of the wire conveying device is elastically connected. Under the action of the first elastic member 404 of the wire conveying device, the first clamping plate 402 of the wire conveying device and the second clamping plate 403 of the wire conveying device are initially separated from each other, so that a first wire passing groove 405 is formed between the first clamping half hole 4021 of the wire conveying device and the second clamping half hole 4031 of the wire conveying device, and a pressure guide wheel 406 is respectively provided on the outer side of the first clamping plate 402 of the wire conveying device and the second clamping plate 403 of the wire conveying device. A first guide rail 407 is provided on the support plate 401, and a first guide block 408 slidably connected to the first guide rail 407 is provided on the first clamping plate 402 and the second clamping plate 403, respectively. A pressing plate 409 is fixed on each of the two outer sides of the wire conveying device support block 23. When the third driving cylinder 24 of the wire conveying device drives the wire conveying device support block 23 to move toward the wire conveying device clamping mechanism 4 in parallel with the first direction of the wire conveying device, the two wire conveying device pressing plates 409 press against a wire conveying device guide pressure wheel 406, respectively. The first wire clamping plate 402 of the wire conveying device and the second wire clamping plate 403 of the wire conveying device respectively overcome the elastic force of the corresponding first elastic member 404 of the wire conveying device and abut against each other, so that the first wire clamping half hole 4021 of the wire conveying device and the second wire clamping half hole 4031 of the wire conveying device each form a wire clamping through hole. At the same time, the third driving cylinder 24 of the wire conveying device drives the wire 20 held in a fixed position by a pair of wire conveying device holding plates 33 to pass through the wire conveying device clamping through hole and be clamped in the wire conveying device clamping through hole. In this way, the first wire clamping plate 402 and the second wire clamping plate 403 can be linked to clamp and release the wire with the movement of the pressing plate 409, thereby facilitating the conveyance of the wire and the subsequent transfer with the workpiece.

[0036] Please refer to Figures 5 to 7Specifically, the clamping mechanism 4 also includes a threading assembly 410, which is arranged between the two clamping plates and the terminal board 21. The threading assembly 410 includes a threading block 4101, a threading detector 4102 and a fourth driving cylinder 4103. The threading detector 4102 can be an infrared detector. The threading block 4101 is provided with a second wire groove 41011 connected to the threading hole. The threading hole and the wire receiving groove 1211 have the same number. The fourth driving cylinder 4103 drives the threading block 4101 to rise and fall to ensure that the wire 20 passes through the threading hole and enters the corresponding clamping through hole under the drive of the third driving cylinder 24. Each threading hole is equipped with a threading detector 4102, and the threading detector 4102 detects whether the wire 20 passes through the threading hole accurately. Therefore, the threading assembly 410 can further ensure that the wire 20 passes through the threading hole accurately and enters the clamping through hole.

[0037] Please refer to Figure 2 , Figures 5 to 7 Specifically, the wire clamping mechanism 4 also includes a fifth driving cylinder 411 and a mounting support plate 412. The mounting support plate 412 is provided with a second guide rail 413 on the first side facing the support plate 401. The support plate 401 is provided with a second guide block 414 slidably connected to the second guide rail 413. The fifth driving cylinder 411 drives the support plate 401 to rise and fall to ensure that the wire 20 accurately passes through the corresponding wire clamping through hole. The clamping mechanism 5 includes a third driver 51 and a pair of claws 52. The third driver 51 is installed on the second side of the mounting support plate 412 facing away from the first side. The third driver 51 drives the pair of claws 52 to be relatively close or relatively far away, so that when the pair of claws 52 are relatively close, they can be used to clamp a workpiece to assemble the wire 20 on the workpiece. After the wire 20 is assembled on the workpiece, the pair of claws 52 are relatively far away, thereby loosening the workpiece so that the workpiece can be transferred. In this case, the pair of claws 52 can not only reliably clamp the workpiece to ensure that the wire 20 is assembled on the workpiece, but also automatically loosen the workpiece so that the workpiece assembled with the wire 20 can be promptly transferred to another wire conveying module by, for example, the flipping mechanism 6.

[0038] Please refer to Figure 1 , Figure 2 , Figure 8 and Fig. 9Specifically, the wire feeding mechanism 1, the wiring mechanism 2, the wire pushing mechanism 3, the wire clamping mechanism 4 and the clamping mechanism 5 are all set to two and each of the various mechanisms constitutes a wire conveying module, and there are two wire conveying modules. It should be noted that the embodiments of the present invention are all described by taking two wire conveying modules as an example, so that one or two wires 20 can be assembled by welding on both sides of the resistor sheet 30 of the liquid level sensor relative to the workpiece, thereby having a high wire assembly efficiency. The wire conveying device also includes a flipping mechanism 6, which flips the workpiece assembled by a wire conveying module and transfers it to another wire conveying module to be assembled again. The flipping mechanism 6 includes a movable plate 61, a sixth driving cylinder 62, a rotating driver 63, a first rotating plate 64, a second rotating plate 65 and a clamping assembly 66. The sixth driving cylinder 62 drives the movable plate 61 to move in a direction parallel to the first direction. The movable plate 61 supports the rotating driver 63. The second rotating plate 65 is fixed to the first rotating plate 64. The rotating driver 63 drives the first rotating plate 64 to drive the second rotating plate 65 to rotate The first rotating plate 64 and the second rotating plate 65 can be split or integrated, so that the workpiece clamped by the clamping mechanism 5 of one wire conveying module can be rotated and transferred to the clamping mechanism 5 of another wire conveying module. The clamping assembly 66 includes a pair of fixedly connected clamping blocks 661 and clamping claws 662 and a second elastic member 663. The second elastic member 663 applies an elastic force to the pair of clamping blocks 661 to move closer to each other. The second elastic member 663 and the first elastic member 404 are specifically springs. A third guide rail 664 is provided on the second rotating plate 65. The extension direction of the third guide rail 664 is opposite to the extension direction of the first guide rail 407. The two clamping blocks 661 are slidably connected to the third guide rail 664 through a third guide block 665, and each of the two clamping blocks 661 is provided with a force block 666. The free ends of the two clamping jaws 662 are provided with a tapered wedge-shaped portion 521. The two clamping jaws 662 are driven by the sixth driving cylinder 62 to move toward the direction of the workpiece clamped by the pair of clamping jaws 662. When the pair of clamping jaws 662 are relatively close to each other under the drive of the third driver 51, when the workpiece is clamped by the pair of clamping jaws 662, the two force blocks 666 respectively move away from each other under the action of the inclined surfaces of the two wedge-shaped portions 521, so that the two clamping jaws 662 are located at the workpiece. In addition to the two clamped parts of the workpiece, after the wire 20 is assembled on the workpiece, the two clamping jaws 662 are driven by the sixth driving cylinder 62 to move in the direction away from the workpiece clamped by the pair of clamping jaws 662 and the pair of clamping jaws 662 are driven by the third driver 51 to move relatively away from each other. At the same time when the workpiece is relaxed by the pair of clamping jaws 662, the two force blocks 666 are gradually no longer subjected to the force of the inclined surfaces of the two wedge-shaped portions 521, and the two clamping blocks 661 are acted on by the elastic force of the second elastic member 663 so that the two clamping jaws 662 approach each other to clamp the two clamped parts of the workpiece, and the clamped workpiece can be rotated toward another wire conveying module.Therefore, the turning mechanism 6 can be provided to transfer the workpiece between different wire conveying modules with high automation and reliability, so as to realize accurate wire assembly on different surfaces of the workpiece.

[0039] Please refer to Figure 8 Specifically, the flipping mechanism 6 also includes a third rotating plate 667 and a seventh driving cylinder 668. The seventh driving cylinder 668 is arranged at one end of the second rotating plate 65 relatively away from the clamping assembly 66. When the clamping assembly 66 is rotated to a horizontal state by the rotating driver 63, the two piston rods of the seventh driving cylinder 668 are extended so that the wire 20 that has been assembled to the workpiece enters the gap between the two extended piston rods in the vertical direction. Then, when the clamping assembly 66 is further rotated to a vertical state by the rotating driver 63 until another relative level, in the process of the wire 20 rotating with the workpiece, the two piston rods are extended to prevent the wire 20 from being deflected, so that the clamped workpiece is rotated to another wire conveying module so that the wire 20 in the other wire conveying module is further assembled to the workpiece, and the two piston rods are shortened to prepare for the next extension. Therefore, the extension of the two piston rods can prevent the wire 20 from being deflected and hooked on other external components during the rotation of the workpiece, and the shortening of the two piston rods can prevent the wire 20 from interfering with the two piston rods before entering the gap between the two piston rods in the vertical direction.

[0040] As another object of the present invention, the present invention further provides a liquid level sensor manufacturing device (not shown), which includes any of the above wire conveying devices, the liquid level sensor manufacturing device includes a plurality of stations, the wire conveying device is correspondingly located at the wire conveying station, Fig. 9The liquid level sensor manufactured by the liquid level sensor manufacturing equipment is shown. The liquid level sensor includes a frame 30, a resistor 30 mounted in the frame 40, and a wire 20 mounted on the resistor. More specifically, the liquid level sensor also includes a rocker arm 50, a spring 60, and a reed 70. The reed 70 is fixed on the rocker arm 50 and the rocker arm 50 is rotatably arranged on the resistor 30. The spring 60 is arranged between the frame 40 and the rocker arm 50 so as to apply an elastic force to the relative position of the reed 70 and the resistor 30. The rocker arm 50 receives, for example, changes in the buoyancy of gasoline in the fuel tank and rotates to different angles relative to the resistor 30, thereby causing the contact on the reed 70 to change the resistance value, thereby achieving the purpose of outputting the sensing signal. The liquid level sensor manufacturing equipment can obtain the beneficial effects brought by any wire conveying device, which will not be repeated here. Therefore, the liquid level sensor manufacturing equipment conveys the wire 20 to the resistor 30 assembled in the skeleton 40 through the wire conveying device, and assembles the fixed end of each wire, that is, the conductive end, with the preset wire end of the resistor 30 in an electrical contact manner such as soldering, so that the liquid level sensor can obtain power supply and output sensing signals through each wire 20, which has the advantages of high wire conveying efficiency and high assembly reliability and accuracy.
